                         13% Senior Discount Notes due
                   April 15, 2007 for any and all outstanding
                  13% Senior Discount Notes due April 15, 2007
                               ------------------
 
THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M., NEW YORK CITY TIME ON             ,
1997 UNLESS EXTENDED.
 
     McCAW INTERNATIONAL, LTD., a Washington corporation (the "Company"), is
hereby offering (the "Exchange Offer"), upon the terms and subject to the
conditions set forth in this Prospectus and in the accompanying Letter of
Transmittal (the "Letter of Transmittal"), to exchange its 13% Senior Discount
Notes due April 15, 2007 (the "Exchange Notes"), which have been registered
under the Securities Act of 1933, as amended (the "Securities Act"), pursuant to
a registration statement of which this Prospectus is a part (together with all
amendments and exhibits thereto, the "Registration Statement"), for an equal
principal amount at maturity of its outstanding 13% Senior Discount Notes due
April 15, 2007 (the "Private Notes"), of which approximately $951.5 million
aggregate principal amount at maturity was issued on March 6, 1997 and is
outstanding on the date hereof.
 
     The Private Notes were sold by the Company in an offering by the Company
(the "Initial Offering") of 951,463 Units (the "Units") exempt from the
registration requirements of the Securities Act, which was consummated on March
6, 1997 (the "Closing Date"). Each Unit issued in the Initial Offering consisted
of one Private Note and one warrant (collectively, the "Warrants") to purchase
 .10616 shares of common stock, without par value, of the Company. The Private
Notes and Warrants will be separately tradeable upon the effectiveness of this
Registration Statement. The Private Notes and Warrants are sometimes
collectively referred to herein as the "Private Securities."
 
   
     The form and terms of the Exchange Notes are identical in all material
respects to those of the Private Notes, except for certain transfer restrictions
and registration rights relating to the Private Notes and except for certain
interest provisions related to such registration rights. The Exchange Notes will
evidence the same indebtedness as the Private Notes (which they replace) and
will be entitled to the benefits of an Indenture dated as of March 6, 1997,
governing the Private Notes and the Exchange Notes (the "Indenture"). The
Exchange Notes will mature on April 15, 2007. No cash interest will be payable
on the Exchange Notes prior to October 15, 2002. Interest on the Exchange Notes
will accrue from April 15, 2002 and will be payable in cash on each April 15 and
October 15, commencing October 15, 2002. The Exchange Notes and payments due in
respect thereof are solely the obligation of the Company and will not be
guaranteed by the Operating Companies (as defined herein). The Private Notes and
the Exchange Notes are sometimes collectively referred to herein as the "Notes."
See "The Exchange Offer" and "Description of the Notes."
    
 
     The Exchange Notes may be redeemed, at the option of the Company, in whole
or in part, at any time on or after April 15, 2002, at the redemption prices set
forth herein, plus accrued and unpaid interest, if any, to the date of
redemption. In addition, prior to April 15, 2000, the Company may redeem up to
35% of the aggregate principal amount at maturity of the Notes with the proceeds
of one or more sales of Capital Stock (other than Redeemable Stock) (each as
defined herein) at the redemption price set forth herein; provided, however,
that after any such redemption at least $618.5 million aggregate principal
amount at maturity of the Notes remains outstanding.    [continued on next page]

                               ------------------
   THE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
 EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
   AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
                               CRIMINAL OFFENSE.

[continued from front cover]
 
    The Exchange Notes will be senior unsecured indebtedness of the Company,
will rank pari passu in right of payment with all unsubordinated unsecured
indebtedness of the Company and will be senior in right of payment to all
subordinated indebtedness of the Company. After giving pro forma effect to the
Transactions (as defined herein) and the Initial Offering, as of December 31,
1996, the Company would have had no indebtedness outstanding other than the
Exchange Notes. All existing and future liabilities (including trade payables)
of the Company's Restricted Group Members (as defined herein) will be
effectively senior to the Exchange Notes. As of December 31, 1996, after giving
effect to the Transactions, the Company's Restricted Group Members would have
had approximately $79.7 million of liabilities, including $25.0 million of
indebtedness.
 
    The Company will accept for exchange any and all validly tendered Private
Notes not withdrawn prior to 5:00 p.m., New York City time, on            ,
1997, unless the Exchange Offer is extended by the Company in its sole
discretion (the "Expiration Date"). Tenders of Private Notes may be withdrawn at
any time prior to the Expiration Date. Private Notes may be tendered only in
integral multiples of $1,000 at maturity. The Exchange Offer is subject to
certain customary conditions. See "The Exchange Offer."
 
   
    The Exchange Notes are being offered hereunder in order to satisfy certain
obligations of the Company under the Registration Rights Agreement, dated as of
March 3, 1997 (the "Registration Rights Agreement"), between the Company and the
Placement Agents (as defined herein). The Company believes that the Exchange
Notes issued pursuant to the Exchange Offer in exchange for the Private Notes
may be offered for resale, resold and otherwise transferred by a holder thereof
(other than (i) a broker-dealer who purchased such Private Notes directly from
the Company to resell pursuant to Rule 144A or any other available exemption
under the Securities Act or (ii) a person that is an affiliate of the Company
within the meaning of Rule 405 under the Securities Act), without compliance
with the registration and prospectus delivery requirements of the Securities
Act; provided, that the holder is acquiring Exchange Notes in the ordinary
course of its business and is not participating, does not intend to participate,
and has no arrangement or understanding with any person to participate, in the
distribution of the Exchange Notes. Holders of Private Notes wishing to accept
the Exchange Offer must represent to the Company that such conditions have been
met. Each broker-dealer that receives Exchange Notes for its own account in
exchange for Private Notes, where such Private Notes were acquired by such
broker-dealer as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a prospectus meeting the
requirements of the Securities Act in connection with any resale of such
Exchange Notes, which contains a plan of distribution with respect to such
resale transactions. The Letter of Transmittal states that by so acknowledging
and by delivering a prospectus, a broker-dealer will not be deemed to admit that
it is an "underwriter" within the meaning of the Securities Act. This
Prospectus, as it may be amended or supplemented from time to time, may be used
by a broker-dealer in connection with any resale of the Exchange Notes received
for Private Notes where such Private Notes were acquired by a broker-dealer as a
result of market-making or other trading activities (other than Private Notes
acquired directly from the Company). The Company has agreed that, for a period
of 180 days after the Expiration Date, it will make this Prospectus available to
any broker-dealer for use in connection with any such resales. See "Plan of
Distribution." The Company believes that none of the registered holders of the
Private Notes is an affiliate (as such term is defined in Rule 405 under the
Securities Act) of the Company.
    
 
   
    The Private Securities have been designated eligible for trading in the
Private Initial Offerings, Resales and Trading through Automated Linkages
("PORTAL") Market of the National Association of Securities Dealers, Inc. (the
"NASD"). The Company does not intend to apply for listing of the Exchange Notes
on any securities exchange or to seek approval through any automated quotation
system nor do the Placement Agents intend to make a market in the Exchange
Notes. There can be no assurance regarding the future development of a market
for the Exchange Notes, or the ability of holders of the Exchange Notes to sell
their Exchange Notes or the price at which such holders may be able to sell
their Exchange Notes. If such a market were to develop, the Exchange Notes could
trade at prices that may be higher or lower than the initial public offering
price depending on many factors, including prevailing interest rates, the
Company's operating results and the market for similar securities. See "Risk
Factors -- Lack of Public Market."
    
 
    Holders of Private Notes whose Private Notes are not tendered and accepted
in the Exchange Offer will continue to hold such Private Notes and will be
entitled to all the rights and preferences and will be subject to the
limitations applicable thereto under the Indenture. Following consummation of
the Exchange Offer, the holders of Private Notes will continue to be subject to
the existing restrictions upon transfer thereof and the Company will have no
further obligation to such holders to provide for the registration under the
Securities Act of the Private Notes held by them.
 
    The Company will not receive any proceeds from, and has agreed to bear all
registration expenses of, the Exchange Offer. No underwriter is being used in
connection with the Exchange Offer. See "The Exchange Offer -- Resale of the
Exchange Notes."

America and two of the largest cities in Asia. The Company's markets cover
approximately 230 million people ("POPs"), approximately 120 million of which
are in Latin America. McCaw International is the largest SMR service provider in
Brazil and Mexico, and holds the largest SMR channel position in Argentina.
McCaw International's strategy is focused on leveraging its leading analog
dispatch or SMR channel positions in its principal markets and using Nextel's
experience and supplier relationships to upgrade its services from analog
dispatch to digital enhanced specialized mobile radio ("ESMR") services. 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.
 
     McCaw International believes that wireless communications opportunities in
emerging markets, particularly in Latin America and Asia, are very attractive
compared to the market in the United States due to the poor telecommunications
infrastructure, low teledensity, favorable competitive environments and greater
expected economic growth rates in those markets. The Company believes that the
low cost of its wireless spectrum relative to cellular and personal
communications services ("PCS"), as well as the large and growing demand for
wireless communications services in its markets, provides it with a significant
opportunity to expand its subscriber base in an efficient and cost-effective
manner.
 
     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 25.2% of the profits generated by a
Global System for Mobile communications ("GSM") network in Shanghai, China (the
"Shanghai GSM System")
 
                                        4

and has a 3.7% interest in Clearnet, a Canadian wireless communications services
company. The foregoing companies and right are referred to in this Prospectus as
the "Operating Companies." The Operating Companies have networks in some of the
largest cities in their respective countries, including Sao Paulo, Mexico City,
Buenos Aires and Rio de Janeiro, which are the four largest cities in Latin
America, and Shanghai and Manila, which are two of the largest cities in Asia.
The subscriber base of the Operating Companies has grown 59% from approximately
111,000 subscribers at December 31, 1995 to approximately 177,000 subscribers at
December 31, 1996.
 
     The Company believes it has established the leading position in terms of
the number of SMR channels in its principal markets. The Company's asset base
includes (i) 5,190 SMR channels in the 800 MHz band (which is adjacent to and
functionally equivalent to cellular frequencies) and the related licenses to
provide wireless communications services over such channels and (ii) deployed
networks in the markets where it operates. The Company's licenses and assets at
January 31, 1997 were acquired for approximately $365 million as of January 31,
1997, or approximately $3.72 per POP, which is significantly less than the
prices paid for cellular and PCS licenses in comparable markets around the
world.
 
     McCaw International currently markets its wireless communications services
primarily to business customers with mobile work forces, such as service
companies, security firms, contractors and delivery services. Companies with
mobile work forces represent growing sectors of the economies in the Company's
markets. These types of businesses often have the need to provide their
personnel with the ability to communicate directly with one another, either on a
one-to-one or a one-to-many basis. By upgrading its operations to provide ESMR
services, the Company will increase capacity significantly and be in a position
to target a broader customer base. The Company currently plans to launch ESMR
commercial service in the Philippines by the end of 1997, in Brazil during the
first quarter of 1998 and in Argentina and Mexico later in 1998. McCaw
International differentiates itself from its competitors by (i) providing
superior quality telecommunications services, (ii) focusing on customer service
and (iii) targeting primarily business customers.
 
     The following table provides a brief overview of each of the Company's
wireless communications systems.

     McCaw International has a senior management team comprised of experienced
executives, most of whom have had substantial experience in the
telecommunications industry and many of whom have been involved in the
development of other telecommunications businesses both in the United States and
in emerging markets. In addition, senior management teams at the Operating
Companies are comprised of both nationals of the countries in which the
Operating Companies are located, most of whom have experience in the
telecommunications industry, as well as U.S. nationals, most of whom have
experience in emerging markets.
 
     McCaw International is an indirect wholly owned subsidiary of Nextel, which
is the largest provider of SMR and ESMR services in the United States with
revenues of approximately $333 million for the year ended December 31, 1996. As
of December 31, 1996, Nextel provided service to approximately 300,000 ESMR
subscriber units. As of February 1, 1997, Nextel had invested approximately $365
million in the Company. A company controlled by Craig O. McCaw, the founder of
McCaw Cellular Communications, Inc. (now AT&T Wireless Services, Inc.), and his
family (collectively, the "McCaw Investor") and Motorola, Inc. ("Motorola") are
significant investors in Nextel.
 
THE MARKETS
 
     The Company has and will continue to target emerging markets characterized
by large unsatisfied demand for telecommunications services, strong long-term
economic growth prospects, highly-concentrated population centers and favorable
competitive environments.
 
     Large, Unsatisfied Demand for Telecommunications Services. The emerging
markets in which the Company operates are characterized by large, unsatisfied
demand for telecommunications services, resulting in long wait lists for phone
lines that range from nine months in Mexico to approximately 3.5 years in Brazil
and as long as nearly nine years in the Philippines. In these markets, wireless
communications are often a substitute for landline telephone service. The
following comparative market estimates illustrate the differences between
telecommunications services in the emerging markets in which the Company
operates and the United States:
 
     - Average of 6.9 access lines per 100 people, compared to 59.4.
 
     - Cellular penetration rate of .7% and SMR penetration rate of .03%,
       compared to 12.8% and 7.0%, respectively.
 
     - Average annual estimated growth rates of cellular subscribers from 1996
       through 2001 of 37% in Latin America and 34% in the Asia Pacific region,
       compared to 17%.
 
     - Average monthly revenue per cellular subscriber and per SMR user of
       approximately $90 and $45, respectively, compared to approximately $51
       and $16, respectively.
 
     Strong Economic Growth Prospects. The Company operates primarily in
emerging markets that it believes offer more favorable long-term economic growth
prospects than developed markets such as the United States. The average real GDP
growth for 1996 in the countries in which McCaw International operates is
projected to be between 5% and 6%, compared to approximately 2% in the United
States.
 
     Highly-Concentrated Population Centers. The Company focuses its operations
in major population centers of emerging markets, including Sao Paulo, Rio de
Janeiro, Buenos Aires, Mexico City, Manila and Shanghai. These cities are
characterized by extremely high population densities and a relatively high
concentration of the country's wealth. In addition, vehicle traffic congestion,
low landline penetration and unreliability of the telecommunications
infrastructure encourage the use of wireless communications services in these
cities.
 
     Favorable Competitive Environments. Although there is large unsatisfied
demand for telecommunications services in the emerging markets in which the
Company operates, there are fewer licensed wireless communications service
providers in most of its markets compared to the United States.
 
STRATEGY
 
     The Company's strategy is to grow by upgrading and expanding its existing
networks to incorporate digital wireless communications services, which will
enable the Company to increase its subscriber base and
 
                                        6
<PAGE>   9
 
revenues, and to pursue new investment opportunities in markets which satisfy
the characteristics described above. The key elements of the Company's strategy
are:
 
     Capitalize on Leading Position. In most of its markets, the Company has a
larger SMR channel position than any other SMR service provider, which allows it
to compete effectively with other wireless communications service providers. Its
large channel positions also reduce the capital expenditures required to upgrade
to digital networks and create operating synergies.
 
     Expand by Providing Digital Enhanced Services. The Company intends to
upgrade its analog SMR networks to digital ESMR networks using Motorola's
integrated digital enhanced network ("iDEN") technology. The upgrade to digital
networks will allow the Company to increase capacity significantly and also
offer additional services and features, which the Company believes will lead to
increases in its subscriber base and average monthly revenue per subscriber.
 
     Develop Cost-Efficient Networks. The Company's strategy of investing in SMR
channels has enabled it to acquire spectrum in its markets at a much lower cost
than cellular and PCS providers have paid in comparable markets around the
world. As a result, the Company believes it has an important competitive
advantage relative to cellular and PCS providers.
 
     Leverage Nextel and Motorola Relationships. Nextel is the largest SMR and
ESMR provider in the United States. The Company intends to access Nextel's
technology, operations, supplier relationships, network development and
marketing expertise in upgrading its SMR networks to ESMR in its existing
markets and to leverage its relationship with Nextel in entering new markets. In
addition, the Company believes that it will benefit from Nextel's relationship
with Motorola, which is expected to supply the Company with iDEN equipment and
services. The Company will have access to financing for iDEN equipment on
substantially similar terms as Nextel under a vendor financing commitment among
Nextel, the Company and Motorola. By utilizing Nextel's expertise and
relationships with suppliers, in particular with Motorola, the Company believes
that it will be able to deploy networks that are competitive with cellular and
PCS networks.
 
     Partner with Strong Local Groups.  McCaw International seeks financially
strong local groups to invest as equity holders at the operating level. The
Company's local partners often own or have access to an existing strategic asset
base (such as real estate for cell sites or distribution outlets) that the
Operating Companies can use to reduce capital expenditures, operating costs and
network deployment time. Local partners also frequently play an active role in
securing licenses, obtaining necessary regulatory approvals and managing
governmental relations for the Operating Companies.
 
     Maintain Active Management Role. The Company seeks to acquire controlling
ownership and management positions in its principal markets to the extent local
law does not restrict foreign ownership or management. Where the Company holds
less than a majority interest in an Operating Company, it manages its investment
through contractual arrangements that, other than in China and Canada, ensure
board representation and enable it to veto certain corporate actions. The
Company actively participates in the management of the Operating Companies,
other than in China and in Canada, by (i) selecting the key members of the local
management team, (ii) developing the system's technology and infrastructure,
(iii) developing business plans and marketing plans together with local
management, and (iv) maintaining close working relationships with local
partners.
 
     Pursue New Investments in Attractive Markets. The Company is continuing to
pursue new investment opportunities in geographic areas that offer attractive
market fundamentals. At present, the Company plans to focus on emerging markets
in Asia and Latin America. The Company believes that such markets offer
favorable long-term economic growth prospects and that geographic concentration
may provide significant business synergies.
 
   
SIGNIFICANT OPERATING LOSSES AND CAPITAL REQUIREMENTS
    
 
   
     For the year ended December 31, 1996, on a pro forma basis after giving
effect to the Transactions (as hereinafter defined) and the Initial Offering,
the Company had negative cash flow from operating activities of $6.0 million,
negative EBITDA of $25.5 million and net losses of $114.2 million. During the
next several years, the Company expects to continue to incur significant and
increasing operating and net losses, negative
    
 
                                        7
<PAGE>   10
 
   
EBITDA and negative cash flow from operations due to the expansion of its
operations and continued build-out and upgrade of its wireless communications
systems. Expansion and upgrade of the Company's existing wireless communications
systems, development of the Company's new systems and the continued funding of
operating losses will require substantial additional cash. See "Risk
Factors -- Short Operating History; Historical and Future Net Operating Losses;
Negative EBITDA" and "-- Significant Capital Requirements for Operations."
    
RECENT EVENTS
   
     Initial Offering. On March 6, 1997, the Company completed the sale of its
Private Notes and Warrants for aggregate net proceeds to the Company of
approximately $482 million. Through April 30, 1997, approximately $36.1 million
of the $482 million in net proceeds to the Company from the Initial Offering of
Private Securities have been used to fund capital expenditures, operating losses
and to make additional investments in the Operating Companies. The remaining net
proceeds are expected to be used for working capital and general corporate
purposes, to fund Partner Contingencies (as defined herein) and to fund
potential acquisitions and investments in existing and new markets.
    
   
     Brazil. On January 30, 1997, Nextel acquired an 81% equity interest in
McCaw Brazil for a purchase price of $186.3 million, which was paid with shares
of Nextel Class A Common Stock ("Nextel Class A Common Stock"), and
simultaneously contributed its interest in McCaw Brazil to the Company. McCaw
Brazil is currently the largest SMR operator in Brazil both in terms of the
number of channels and the number of subscribers in its licensed service areas.
The Company is currently in discussions with several large Brazilian corporate
groups regarding the possible sale of up to a 15% equity interest in a holding
company (the "Brazil Holding Company") to be formed by McCaw Brazil (the "Brazil
Equity Sale"). The proceeds from any such sale will be applied to the build-out
of McCaw Brazil's ESMR network. There can be no assurance that the Company will
be able to consummate any such transaction.
    
   
     On April 26, 1997 and in the beginning of June 1997, news reports appeared
in Brazilian newspapers and international wire services that an anonymous source
had forwarded to the Brazilian Ministry of Communications (the "Ministry of
Communications") a copy of the Company's offering memorandum prepared in
connection with the Initial Offering and a letter alleging that the Company was
operating in Brazil without authorization from the Ministry of Communications.
Based upon these allegations, the Ministry of Communications sent the Company a
letter requesting its comments to the allegations and the Company sent the
Ministry of Communications a letter responding to such allegations. Further,
certain members of the Brazilian Congress introduced legislation that would
eliminate the guaranteed right of SMR providers to interconnect to the public
telecommunications network. Such legislation was enacted on July 16, 1997.
Additionally, on May 15, 1997 and June 25, 1997, the Ministry of Communications
issued proposed regulations for public comment that, if approved as drafted,
would impose limitations on the Company's ability to (i) obtain direct telephone
numbers for all of its subscriber units in Brazil and (ii) interconnect with the
public telecommunications network. Although the Company believes that the
current regulatory framework permits the operation of its existing business in
Brazil, the proposed regulations, if enacted as drafted, may limit the Company's
current and future operations in Brazil. Furthermore, there can be no assurance
that the Brazilian Congress or the Ministry of Communications will not modify
the existing regulatory framework, or that the Ministry of Communications will
not initiate administrative proceedings to impede the Company from providing the
existing SMR services or launch ESMR services.
    
   
     Argentina. The Company consummated the Argentina Transaction on May 6,
1997. As a result of the Argentina Transaction, the Company doubled its spectrum
position in Argentina, became the largest SMR channel holder in Argentina and
became the holder of a nationwide paging business that currently has
approximately 4,000 subscribers. The Company currently owns a 50% interest in
McCaw Argentina.
    
   
     Indonesia. The Company has entered into an agreement in principle with one
of the twenty largest companies in Indonesia (the "Indonesian Partner") to form
a joint venture to pursue construction and operation of a nationwide SMR system
(the "Indonesian Joint Venture"). Indonesia has a population of approximately
197 million persons. The Company expects to finalize a definitive agreement by
the end of the
    
 
                                        8
<PAGE>   11
 
   
third quarter of 1997. The Company is also in discussions with the Indonesian
Partner to bid for regional PCS licenses in Indonesia in the near term. No
assurance can be given that the Company will be able to consummate the
Indonesian Joint Venture or any other transaction with the Indonesian Partner.
    
 
   
     Mexico. On February 26, 1997, Mobilcom shareholders approved a $27 million
capital call (the "Mobilcom Capital Call"). Nextel funded the Company's pro rata
share of the Mobilcom Capital Call (approximately $10 million) with a cash
contribution. Additionally, because not all of the Mobilcom shareholders funded
their pro rata share of the Mobilcom Capital Call, the Company had the
opportunity to purchase additional shares of Mobilcom by funding the
unsubscribed portion of the Mobilcom Capital Call (approximately $10 million).
The Company thereby increased its equity interest in Mobilcom from approximately
38% to approximately 46.3%. The Company funded its purchase of the unsubscribed
shares from the net proceeds of the Initial Offering. The funds from the
Mobilcom Capital Call were used by Mobilcom to satisfy certain overdue
obligations (approximately $11 million), to purchase the remaining 51% of
Nacional de Telecomunicaciones S.A. de C.V. ("Natel") that Mobilcom did not own
and to fund operations. The Natel acquisition was consummated on April 16, 1997.
    
 
   
     On June 30, 1997, the Company purchased shares representing approximately
1.8% of Mobilcom's issued and outstanding capital from a then-current
shareholder of Mobilcom for approximately $3.2 million. As a result of such
transaction, the Company's equity interest in Mobilcom increased to 48.1%.
    
 
   
     Canada. On June 26, 1997, Nextel announced that it completed its
solicitation process whereby Nextel received the consent of the holders of its
public notes to certain amendments to the indentures governing such notes. The
Nextel noteholders agreed, among other things, to permit Nextel to transfer its
equity interest in Clearnet to McCaw International. If Nextel effects such
transfer, McCaw International will hold an aggregate of 8,373,845 shares of
Clearnet, representing approximately 19% of the outstanding common stock of
Clearnet, which represents a 1.7% voting interest. As of June 30, 1997, based on
the closing price of Clearnet stock on the Nasdaq Stock Market, Nextel's equity
interest in Clearnet had a market value of approximately $82 million. Although
Nextel is permitted to transfer its interest in Clearnet to the Company, there
can be no assurance that Nextel will effect such transfer or, should such
transfer occur, that the market value of Nextel's equity interest in Clearnet on
the date of any such transfer will not be less than the market value of such
equity interest as of June 30, 1997.
    
 
   
     Stock Option Plan. On June 23, 1997, the board of the directors of the
Company adopted, subject to the approval of Nextel, the Company's sole
shareholder, the McCaw International, Ltd. 1997 Stock Option Plan (the "1997
Stock Option Plan") and approved a plan to terminate the McCaw International,
Ltd. Stock Appreciation Rights Plan (the "SAR Plan"). Each holder of stock
appreciation rights ("SARs") granted previously under the SAR Plan has been
given the right to exchange his or her SARs for options to be granted under the
1997 Stock Option Plan. The Company has agreed to grant additional stock options
to SAR holders who exchange their SARs for stock options as an inducement to
such SAR holders. The Company expects holders representing a substantial
majority of the outstanding SARs, including all of the members of the Company's
senior management team, to exchange their SARs for options granted under the
1997 Stock Option Plan. See "Management -- Benefit Plans."

                             maturity of Private Notes outstanding. See "The
                             Exchange Offer."
 
                             Based on interpretations by the staff of the
                             Commission set forth in no-action letters issued to
                             third parties, the Company believes that the
                             Exchange Notes issued pursuant to the Exchange
                             Offer in exchange for Private Notes may be offered
                             for resale, resold and otherwise transferred by a
                             holder thereof without compliance with the
                             registration and prospectus delivery provisions of
                             the Securities Act, provided that the holder is
                             acquiring Exchange Notes in the ordinary course of
                             its business, is not participating, does not intend
                             to participate and has no arrangement or
                             understanding with any person to participate in the
                             distribution of the Exchange Notes and is not an
                             "affiliate" of the Company within the meaning of
                             Rule 405 under the Securities Act. Each
                             broker-dealer who holds Private Notes acquired for
                             its own account as a result of market-making or
                             other trading activities and who receives Exchange
                             Notes pursuant to the Exchange Offer for its own
                             account in exchange therefor must acknowledge that
                             it will deliver a prospectus in connection with any
                             resale of such Exchange Notes.
 
                             This Prospectus, as it may be amended or
                             supplemented from time to time, may be used by a
                             broker-dealer in connection with resales of
                             Exchange Notes received in exchange for Private
                             Notes acquired by such broker-dealer as a result of
                             market-making activities or other trading
                             activities. The Letter of Transmittal that
                             accompanies this Prospectus states that by so
                             acknowledging and by delivering a prospectus, a
                             broker-dealer will not be deemed to admit that it
                             is an "underwriter" within the meaning of the
                             Securities Act. Any holder of Private Notes who
                             tenders in the Exchange Offer with the intention to
                             participate in a distribution of the Exchange Notes
                             could not rely on the above-referenced position of
                             the staff of the Commission and, in the absence of
                             an exemption under the Securities Act, would have
                             to comply with the registration and prospectus
                             delivery requirements therein in connection with
                             any resale transaction. Failure to comply with such
                             requirements in such instance could result in such
                             holder incurring liability under the Securities Act
                             for which the holder is not indemnified by the
                             Company. See "The Exchange Offer -- Resale of the
                             Exchange Notes."

                             Agents") pursuant to a Placement Agreement, dated
                             as of March 3, 1997 (the "Placement Agreement"),
                             between the Company and the Placement Agents.
                             Pursuant to the Placement Agreement, the Company
                             entered into the Registration Rights Agreement with
                             the Placement Agents, which agreement grants the
                             holders of Private Notes certain exchange and
                             registration rights. The Exchange Offer is intended

                             satisfy, as to all Notes, such rights, which will
                             terminate upon the consummation of the Exchange
                             Offer. The holders of the Exchange Notes will not
                             be entitled to any exchange or registration rights
                             with respect to the Exchange Notes. Holders of
                             Private Notes who do not participate in the
                             Exchange Offer may thereafter hold a less liquid
                             security. See "The Exchange Offer -- Termination of
                             Certain Rights." The Company will not receive any
                             proceeds from and has agreed to bear the expenses
                             of the Exchange Offer.

                             sole discretion, in which case the term "Expiration
                             Date" shall mean the latest date and time to which
                             the Exchange Offer is extended. See "The Exchange
                             Offer -- Expiration Date; Extensions; Amendments."

                             and therein, and mail or otherwise deliver such
                             Letter of Transmittal, or such facsimile, together
                             with such Private Notes and any other required
                             documentation to The Bank of New York, as Exchange

                             forth herein. By executing the Letter of
                             Transmittal, the holder will represent to and agree
                             with the Company that, among other things, (i) the

                             Private Notes in connection with the Exchange Offer
                             are being acquired by such holder in the ordinary

                             will receive Exchange Notes for its own account in
                             exchange for Private Notes that were acquired as a
                             result of market-making or other trading
                             activities, such holder will be required to
                             acknowledge in the Letter of Transmittal that such
                             holder will deliver a prospectus in connection with
                             any resale of such Exchange Notes; however, by so
                             acknowledging and by delivering a prospectus, such
                             holder will not be deemed to admit that it is an
                             "underwriter" within the meaning of the Securities
                             Act. See "The Exchange Offer -- Procedures for

  Beneficial Owners........  Any beneficial owner whose Private Notes are
                             registered in the name of a broker, dealer,
                             commercial bank, trust company or other nominee and

                             owner's own behalf, such owner must, prior to
                             completing and executing the Letter of Transmittal

                             maturity of the Notes remains outstanding. See

                             right of payment to all subordinated indebtedness
                             of the Company. After giving pro forma effect to
                             the Transactions and the Initial Offering as of
                             December 31, 1996, the Company would have had no
                             indebtedness outstanding other than the Notes. All
                             existing and future liabilities (including trade
                             payables) of the Company's Restricted Group Members
                             (as defined under "Description of the Notes") will
                             be effectively senior to the Notes. As of December
                             31, 1996 after giving effect to the Transactions,
                             the Company's Restricted Group Members would have
                             had $79.7 million of liabilities, including $25.0
                             million of indebtedness. See "Risk
                             Factors -- Substantial Indebtedness; Ability to
                             Service Debt; Refinancing Risks" and "-- Holding
                             Company Structure; Effective Subordination; Secured
                             Indebtedness."
 
Change of Control..........  Upon a Change of Control (as defined under
                             "Description of the Notes -- Certain Definitions"),
                             the Company will be required to make an offer to
                             purchase the Notes at a purchase price equal to
                             101% of their Accreted Value on the date of
                             purchase, plus accrued interest. There can be no
                             assurance that the Company will have sufficient
                             funds available at the time of any Change of
                             Control to make any required debt repayment
                             (including repurchases of the Notes). See
                             "Description of the Notes -- Repurchase of Notes
                             Upon a Change of Control."
 
Certain Covenants..........  The Indenture contains certain covenants for the
                             benefit of the holders of the Notes (the "Holders")
                             which, among other things, restrict the ability of
                             the Company and each Restricted Group Member to
                             incur additional indebtedness, create liens, engage
                             in sale-leaseback transactions, pay dividends or
                             make distributions in respect of their capital
                             stock, make investments or certain other restricted
                             payments, sell assets, issue or sell stock of
                             Restricted Group Members, enter into transactions
                             with stockholders or affiliates or effect a
                             consolidation or merger. These limitations will,
                             however, be subject to important qualifications and
                             exceptions. See "Description of the
                             Notes -- Covenants."

Book-Entry, Delivery
  and Form.................  It is expected that delivery of the Exchange Notes
                             will be made in book-entry or certificated form.
                             The Company expects that Exchange Notes exchanged
                             for Private Notes currently represented by Global
                             Notes (as defined under "Description of Exchange
                             Notes") deposited with, or on behalf of The
                             Depository Trust Company (the "Depository" or
                             "DTC") and registered in the name of Cede & Co.,
                             its nominee, will be represented by Global Notes
                             and deposited upon issuance with the Depository and
                             registered in its name or the name of its nominee.
                             Beneficial interests in Global Note(s) representing
                             the Notes will be shown on, and transfers thereof
                             will be effected through, records maintained by the
                             Depository and its participants.
 
     For additional information regarding the Notes, see "Description of the
Notes" and "Certain U.S. Federal Income Tax Considerations."
 
                        NO CASH PROCEEDS TO THE COMPANY
 
     This Exchange Offer is intended to satisfy certain obligations of the
Company under the Registration Rights Agreement. The Company will not receive
any proceeds from the issuance of the Exchange Notes offered hereby and has
agreed to pay the expenses of the Exchange Offer. In consideration for issuing
the Exchange Notes as contemplated in this Prospectus, the Company will receive,
in exchange, the Private Notes representing an equal aggregate principal amount
at maturity. The form and terms of the Exchange Notes are identical in all
material respects to the form and terms of the Private Notes, except as
otherwise described herein under "The Exchange Offer Terms of the Exchange
Offer." The Private Notes surrendered in exchange for Exchange Notes will be
retired and canceled and cannot be reissued. Accordingly, issuance of the
Exchange Notes will not result in any increase in the outstanding indebtedness
of the Company.

                      SUMMARY CONSOLIDATED FINANCIAL DATA
   
     The following table sets forth summary consolidated financial and operating
data of the Company for the year ended December 31, 1996, the three months ended
March 31, 1996, and as of and for the three months ended March 31, 1997. The
summary consolidated financial data of the Company for the year ended December
31, 1996, with the exception of data presented under Other Financial Data, were
derived from the consolidated financial statements of the Company and the notes
thereto, which have been audited by Deloitte & Touche LLP, independent auditors,
whose report has been included herein. The summary consolidated historical
financial data of the Company for the three months ended March 31, 1996, and as
of and for the three months ended March 31, 1997 and the pro forma data are
unaudited and are derived from the Company's unaudited consolidated financial
statements. The pro forma consolidated statements of operations give effect to
the Transactions (as defined herein) and the Offering as if they occurred on
January 1, 1996, and the pro forma consolidated balance sheet data give effect
to the Argentina Transaction and the capital contribution that increased the
Company's interest in Mobilcom from 38% to 46.3% as if they occurred on March
31, 1997. The pro forma data are not necessarily indicative of the results that
would have been achieved by the Company, nor are they indicative of the
Company's future results.
    
   
     The summary consolidated financial and operating data should be read in
conjunction with "Selected Consolidated Historical Financial Data," "Pro Forma
Consolidated Financial Statements," including the notes thereto, "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
the consolidated financial statements of the Company, WVB and Mobilcom including
the notes thereto, and the other financial and operating information appearing
elsewhere in this Prospectus.

</TABLE>
    
 
- ---------------
   
(1) The pro forma data give effect to the following transactions (collectively,
    the "Transactions") in each case as if they had occurred on January 1, 1996:
    (i) Nextel's acquisition of an 81.0% interest in WVB for $186.3 million in
    market value of Nextel Class A Common Stock and the simultaneous
    contribution of such interest to the Company; (ii) the Company's acquisition
    of an approximately 38% interest in Mobilcom for $76.9 million, and the
    subsequent capital contribution that increased the Company's interest in
    Mobilcom from 38% to 46.3%, which are accounted for using the equity method;
    (iii) the Company's acquisition of a 30.0% interest in Infocom
    Communications Network, Inc. ("Infocom"), accounted for using the equity
    method; (iv) The Argentina Transaction; and (v) the pre-merger transfer to
    Nextel of NIC's assets and liabilities not associated with the Company's
    investments in Mobilcom and Clearnet. The pro forma data also give effect to
    the Initial Offering as if it had occurred on January 1, 1996. See "The
    Company."
    
   
(2) Under U.S. GAAP, approximately $14.8 million of the proceeds of the Initial
    Offering has been allocated to the Warrants and $485.2 million of the
    proceeds has been allocated to the Notes.
    
   
(3) "EBITDA" consists of loss before interest expense, income tax benefit
    (provision) and depreciation and amortization. EBITDA is provided because it
    is a measure commonly used in the telecommunications industry. It is
    presented to enhance an understanding of the Company's operating results and
    is not intended to represent cash flow or results of operations for the
    periods presented. EBITDA is not a measurement under U.S. GAAP and may not
    be similar to EBITDA measures of other companies. See the Company's
    consolidated financial statements and the notes thereto appearing elsewhere
    in this Prospectus.
    
   
(4) For the purpose of computing the ratio of earnings to fixed charges,
    earnings consist of loss before income taxes, plus fixed charges, less
    income (loss) from equity method investments. Fixed charges consist of
    interest on all indebtedness, amortization of debt expense, and that portion
    of rental expense which the Company believes to be representative of
    interest. The deficiency for purposes of calculating the ratio of earnings
    to fixed charges for the year ended December 31, 1996 for actual and pro
    forma was $11,121,352 and $114,981,457, respectively, for the three months
    ended March 31, 1996 was $958,247 and for the three months ended March 31,
    1997 for actual and pro forma was $10,309,587 and $27,200,856, respectively.
    
   
(5) Gives pro forma effect to the Argentina Transaction and the capital
    contribution that increased the Company's interest in Mobilcom from 38% to
    46.3% as if they occurred on March 31, 1997.

                                  RISK FACTORS
 
     In addition to the other information contained in this Prospectus, the
following risk factors should be carefully considered in evaluating the Company
and its business before deciding whether or not to tender Private Notes in
exchange for Exchange Notes pursuant to the Exchange Offer. A number of the
matters and subject areas discussed in this Prospectus are not historical or
current facts but rather address potential future circumstances and
developments. The discussion of such matters and subject areas is qualified by
the inherent risks and uncertainties surrounding future expectations generally,
and also may materially differ from the Company's actual future experience
involving any one or more of such matters and subject areas. The Company has
attempted to identify certain of the factors that it currently believes may
cause actual future experience and results to differ from the Company's current
expectations regarding the relevant matter or subject area. The operation and
results of the Company's wireless communications operations also may be subject
to the effect of other risks and uncertainties in addition to the relevant
qualifying factors identified elsewhere herein, including, but not limited to,
general economic conditions in the countries and markets in which the Operating
Companies offer their wireless communications services, the availability of
adequate quantities of system infrastructure and subscriber equipment and
components to meet the Company's service deployment and marketing plans and
customer demand, the successful deployment of the technologies chosen by the
Operating Companies, the ability to achieve market penetration and average
subscriber revenue levels sufficient to provide financial viability to the
Operating Companies, access to sufficient debt or equity capital to meet the
Company's operating and financing needs, the quality and price of similar or
comparable wireless communications services offered or to be offered by the
Company's competitors, future legislative or regulatory actions relating to
wireless communications services in the countries in which the Operating
Companies are offering their services and other risks and uncertainties
described throughout this Prospectus.
 
   
     SHORT OPERATING HISTORY; HISTORICAL AND FUTURE NET OPERATING LOSSES;
NEGATIVE EBITDA. Each of the Operating Companies has a short operating history.
Additionally, the Company plans to acquire or commence additional operations in
markets in which it currently does not operate and any such additional
operations will likely have either a limited or no operating history. The
Company's prospects must therefore be considered in light of the risks,
expenses, uncertainties and obstacles inherent in establishing a new business in
an evolving industry. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations." For the year ended December 31, 1996, on a
pro forma basis after giving effect to the Transactions and the Initial
Offering, the Company had negative cash flow from operating activities of $6.0
million, negative EBITDA of $25.5 million and net losses of $114.2 million. In
particular, Mobilcom has incurred significant operating and net losses. The
Company has recently taken steps that are intended to improve the operating
performance of Mobilcom and expects to take additional steps in the future,
although no assurance can be given that such efforts will be successful. In some
of the Operating Companies, the Company has experienced relatively high rates of
churn and bad debt expenses. However, the Company has taken a number of steps to
reduce these levels including tightening the credit screening process,
instituting the requirement of longer term contracts and formulating more
aggressive collection processes. During the next several years, the Company
expects to continue to incur significant and increasing operating and net
losses, negative EBITDA and negative cash flow from operations due to the
expansion of its operations and continued build-out and upgrade of its wireless
communications systems. There can be no assurance that the Company will achieve
or sustain profitability or positive cash flow from operations in the future. If
the Company cannot achieve operating profitability or positive cash flow from
operations, it may not be able to meet its debt service or working capital
requirements (including its obligations with respect to the Notes).
    
 
   
     SUBSTANTIAL INDEBTEDNESS; ABILITY TO SERVICE DEBT; REFINANCING RISKS. At
December 31, 1996, on a pro forma basis after giving effect to the Transactions
and the Initial Offering, the Company would have had no indebtedness outstanding
other than the Notes. The accretion of original issue discount on the Notes will
cause an increase in liabilities from the Closing Date of approximately $466.3
million by April 15, 2002. Additionally, on the same pro forma basis, for the
year ended December 31, 1996, the Company's deficiency of earnings before fixed
charges to cover fixed charges would have been $115.0 million and EBITDA would
have been negative $25.5 million. The Indenture limits, but does not prohibit,
the incurrence of additional indebtedness by the Company and certain of its
affiliates and subsidiaries. The Company anticipates that it
    
 
                                       17
<PAGE>   20
 
and the Operating Companies will incur substantial additional indebtedness in
the future. Indebtedness incurred by the Operating Companies includes and is
expected to continue to include financing provided by Motorola to fund the
purchase of equipment from Motorola (the "Motorola Financing") as well as other
vendor financing. The Indenture does not limit the amount of vendor financing
indebtedness that may be incurred. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
     The Indenture restricts, among other things, the Company's, and certain of
its subsidiaries' and affiliates', ability to incur indebtedness, create liens,
pay dividends or make certain other restricted payments, sell assets, enter into
certain transactions with affiliates or merge or consolidate with any other
person. In addition, the Motorola Financing includes and any other vendor
financing (including additional Motorola Financing) is expected to include
restrictive covenants, including prohibitions on the Operating Companies'
ability to pay dividends. It is expected that all of an Operating Company's
assets and capital stock will be pledged to secure such Operating Company's
obligations under the Motorola Financing. Because the Motorola Financing may
mature after the time that cash interest payments on the Notes are required, as
long as any Motorola Financing at an Operating Company remains outstanding, such
Operating Company will be unable to pay dividends to the Company as a source of
cash to make interest payments on the Notes and the Company would therefore need
to obtain funds from other sources.
 
   
     The level of the Company's indebtedness could have important consequences
to Holders, including the following: (i) the debt service requirements of any
additional indebtedness could make it more difficult for the Company to make
payments of interest on the Notes; (ii) the ability of the Company to obtain any
necessary financing in the future for working capital expenditures, debt service
requirements or other purposes may be limited or at terms which are not
favorable to the Company; (iii) a substantial portion of the Company's cash flow
from operations, if any, must be dedicated to the payment of principal and
interest on its indebtedness and other obligations, and will not be available
for use in its business; (iv) the Company's level of indebtedness could limit
its flexibility in planning for, or reacting to, changes in its business; (v)
the Company is more highly leveraged than some of its competitors, which may
place it at a competitive disadvantage; and (vi) the Company's high degree of
indebtedness will make it more vulnerable in the event of a downturn in its
business.
    
 
   
     The Company believes that cash flows from the planned expansion of its
existing operations will be sufficient to meet its debt service obligations;
however, there can be no assurance in this regard. The Company must
substantially increase its net cash flow in order to meet its debt service
obligations, including its obligation under the Notes. If the Company is unable
to generate sufficient cash flow or otherwise obtain funds necessary to make
required payments, or if it otherwise fails to comply with the various covenants
in its indebtedness, it would be in default under the terms thereof, which would
permit the holders of such indebtedness to accelerate the maturity of the
indebtedness and could cause defaults under other indebtedness of the Company.
Such defaults could result in a default on the Notes and could delay or preclude
payment of interest or principal thereon. The Company's ability to meet its
obligations will depend on its future performance, which will be subject to
prevailing economic conditions and to financial, business and other factors,
including factors beyond the Company's control.
    
 
     The Motorola Financing matures and other financing (including additional
Motorola Financing) may mature prior to the maturity of the Notes. The Company
also expects that existing and future Motorola Financing and other financing may
need to be refinanced at their respective maturities and that the Notes also may
need to be refinanced when cash interest becomes payable. The Company's ability
to refinance its indebtedness will depend, among other factors, on its financial
condition at the time, the restrictions contained in the instruments governing
its other indebtedness and other factors beyond the Company's control, including
market conditions. There can be no assurance that the Company will be able to
refinance any existing or future Motorola Financing, any other financing or the
Notes. If the Motorola Financing or such other financing cannot be refinanced,
it may cause a default under the Notes and the Company may be unable to meet its
obligations under the Notes.
 
     SIGNIFICANT CAPITAL REQUIREMENTS FOR OPERATIONS. Expansion and upgrade of
the Company's existing wireless communications systems, development of the
Company's new systems and the continued funding of
 
                                       18
<PAGE>   21
 
   
operating losses will require substantial additional cash. The Company believes
that the net proceeds from the Initial Offering, together with borrowings
expected to be available under vendor financing, including the Motorola
Financing and the estimated proceeds from the Brazil Equity Sale, if
consummated, will be sufficient to fund the Company's current operations,
including the planned expansion of its existing operations, for approximately 36
to 48 months from the Closing Date; however, there can be no assurance in this
regard. Thereafter, the Company will need substantial additional cash. If the
Company's plans or assumptions change, if its assumptions prove to be
inaccurate, if it consummates investments or acquisitions in addition to those
currently contemplated, if it experiences unanticipated costs or competitive
pressures, if the Brazil Equity Sale is not consummated, or if the net proceeds
from the Initial Offering, together with the proceeds of any such borrowings
otherwise prove to be insufficient, the Company may be required to seek
additional capital sooner than currently anticipated. The Company may seek to
raise such additional capital from public or private equity or debt sources.
There can be no assurance that the Company will be able to raise such capital on
satisfactory terms, if at all. If the Company decides to raise additional funds
through the incurrence of debt, it may become subject to additional or more
restrictive financial covenants and its interest obligations will increase. In
the event that the Company is unable to obtain such additional capital or to
obtain it on acceptable terms, it may be required to reduce the scope of its
presently anticipated expansion, which could have a material adverse effect on
its ability to compete, and its ability to meet its obligations on the Notes.
The terms of any borrowings under the Motorola Financing are subject to
negotiation and execution of definitive agreements. The Company does not have a
revolving credit facility or any other credit facility providing funding for the
Company. Nextel is not obligated to provide any additional funds to the Company.
    
 
     CONTINGENT CAPITAL REQUIREMENTS. The need for significant additional
capital may also be affected by arrangements the Company has with other
investors in the Operating Companies. In order to retain the contractual right
to designate a majority of the board of directors of Mobilcom, a member of the
Technology Committee of such board of directors and to block certain significant
actions of Mobilcom, the Company must have invested approximately $76.8 million
(the "Minimum Amount") in Mobilcom through certain qualified capital
transactions by March 1998. See "Business -- Operations and
Investments -- Corporate Governance -- Mexico." As of April 30, 1997 the Company
had invested approximately $63.7 million in such qualified capital transactions.
In addition, beginning on October 24, 1997, holders of approximately 37% of the
outstanding capital stock of Mobilcom have the right for two years to put (the
"Mobilcom Put") the entire amount of their holdings to the Company at its
appraised fair market value for cash. The Mobilcom Put is exercisable if
Mobilcom takes any of the following corporate actions and the directors
designated to Mobilcom's board of directors by the holders of the Mobilcom Put
voted against such action: (i) a material amendment of the charter or bylaws;
(ii) issuance of voting securities with disproportionately larger voting rights
or a class vote; (iii) certain issuance of shares in excess of 15% of the
outstanding shares during a 36-month period; (iv) making any investment, loaning
any amount, or selling assets in excess of $20 million; (v) the adoption of, or
material deviation from, any business plan, operating budget or capital
expenditure plan; and (vi) making capital expenditures that would exceed 125% of
the capital expenditure budget approved by the shareholders (collectively, the
"Mobilcom Put Events"). In addition, the Mobilcom Put is exercisable in the
event that the holders of the Mobilcom Put are no longer entitled to designate
in the aggregate at least two directors. The Mobilcom Put is also automatically
exercisable on October 24, 1999 whether or not a Mobilcom Put Event occurs.
Valuation of Mobilcom for purposes of the Mobilcom Put will be based on an
appraisal by an investment bank, with the minimum appraisal for 100% of Mobilcom
equal to $150 million. To the extent such appraisal exceeds $250 million, 50% of
such excess will be included in the valuation. In connection with a capital call
on June 7, 1996, Mobilcom shareholders purchased additional shares of Mobilcom
based on a $200 million valuation of Mobilcom (which values the Mobilcom Put at
approximately $66 million). If the Company does not pay the Minimum Amount and
to the extent the Company does not otherwise acquire a majority of the
outstanding capital stock of Mobilcom, the Company will lose its right to
designate a majority of the board of directors of Mobilcom and a member of the
Technology Committee and its ability to block certain significant actions of
Mobilcom. The Company has the option to purchase, before March 3, 1998, up to an
additional 29.5% of Mobilcom's common stock. To the extent the Company owns a
majority of the voting stock in Mobilcom after giving effect to the exercise of
the Mobilcom Put, the Company will not be affected by the failure to have
invested the Minimum Amount by
 
                                       19
<PAGE>   22
 
March 1998 because its equity ownership will entitle it to elect a majority of
the board of directors of Mobilcom. As of April 30, 1997, the Company owned
approximately 46.3% of the voting stock of Mobilcom. See "Business
 -- Operations and Investments -- Corporate Governance -- Mexico."
 
     The other shareholder in McCaw Brazil has the right between October 31,
2001 and November 1, 2003, to require McCaw Brazil to redeem such shareholder's
19% interest in McCaw Brazil at fair market value as determined pursuant to an
appraisal procedure (the "McCaw Brazil Put"). The Minimum Amount and any amounts
required to satisfy the Company's obligations with respect to the Mobilcom Put
and the McCaw Brazil Put are collectively referred to as the "Partner
Contingencies."
 
     The Company anticipates funding the Partner Contingencies with the net
proceeds of the Initial Offering, issuances of additional debt and equity
securities at the Company and Operating Company levels, future equity
investments in the Operating Companies by new local partners and capital
contributions from Nextel in the form of cash or Nextel common stock. Nextel has
no obligation to provide any such financing and there can be no assurance that
the Company will be able to fund the Partner Contingencies. The failure to fund
a Partner Contingency may have a material adverse effect on the Company.
 
     HOLDING COMPANY STRUCTURE; EFFECTIVE SUBORDINATION; SECURED INDEBTEDNESS.
The Company intends to invest or loan substantially all of the net proceeds from
the Initial Offering in or to the Operating Companies. As of April 30, 1997, the
Company had invested approximately $36.1 million of the net proceeds from the
Initial Offering in the Operating Companies. The Company is a holding company
and therefore must rely on dividends and other payments from the Operating
Companies to generate the funds necessary to meet its obligations, including the
payment of principal and interest on the Notes. The Operating Companies are
legally distinct from the Company and have no obligation, contingent or
otherwise, to pay amounts due with respect to the Notes, or to make funds
available for such payments. The Operating Companies will not guarantee the
Notes. Additionally, the Operating Companies and subsidiaries through which the
Company holds its interests in certain of the Operating Companies are organized
in jurisdictions outside the United States. The ability of the Operating
Companies to make distributions to the Company will be subject to, among other
things, the availability of funds, contractual restrictions and applicable local
laws. Certain of the Operating Companies have entered into financing facilities
that prohibit or restrict the payment of dividends. It is expected that each
Operating Company that is party to the Motorola Financing will be prohibited
from paying dividends until such Motorola Financing is repaid, which may occur
after the time cash interest is required to be paid on the Notes. In addition,
the payment of dividends by each of the Operating Companies other than McCaw
Brazil requires the approval of certain of the other equity holders in such
companies.
 
   
     Claims of creditors of the Operating Companies, including trade creditors,
will generally have priority as to the assets of such Operating Companies over
the claims of the Company and the holders of the Company's indebtedness.
Accordingly, the Notes will be effectively subordinated to the liabilities of
the Operating Companies. Any right of the Company to receive assets of any
Operating Company upon the liquidation or reorganization of such Operating
Company (and the consequent right of the Holders to participate in those assets)
will be effectively subordinated to the claims of such Operating Company's
creditors, except to the extent that the Company is itself recognized as a
creditor, in which case the claims of the Company would still be subordinate to
any security in the assets of such Operating Company (including the assets of
such Operating Company securing its Motorola Financing) and any indebtedness of
such Operating Company senior to that held by the Company. In addition, holders
of secured indebtedness of the Company would have a claim on the assets securing
such indebtedness that is prior to the Holders of the Notes and would have a
claim that is pari passu with the Holders of the Notes to the extent such
security did not satisfy such indebtedness. As of April 30, 1997, the Company
has no significant assets other than the stock of the Operating Companies and
approximately $445.9 of the net cash proceeds from the Initial Offering which
has been invested in short term investments. It is expected that the stock of
the Operating Companies owned by the Company will be pledged to secure the
Motorola Financing or other indebtedness and that substantially all of the net
cash proceeds from the Initial Offering will be invested in or loaned to the
Operating Companies. A substantial portion of the assets of the Operating
Companies consists of goodwill, licenses and other intangibles. As of December
31, 1996, after giving effect to the Transactions, the Company's Restricted
Group Members would have had approximately $79.7 million of liabilities,
including $25.0 million of indebtedness.

     MINORITY INTERESTS; SHAREHOLDER CONSENT REQUIREMENTS. The Company intends
to invest or loan substantially all of the net proceeds from the Initial
Offering in or to the Operating Companies. As of April 30, 1997, the Company had
invested approximately $36.1 of the net proceeds from the Initial Offering in
the Operating Companies. The Company currently has, and anticipates that it will
make in the future, minority investments in international wireless
communications operations, partly because of limitations on foreign ownership in
telecommunications companies in some countries. The Company's ability to
withdraw funds from the Operating Companies other than from McCaw Brazil,
including through the payment of dividends, depends in all cases on receiving
the consent of certain other stockholders of those companies, over which the
Company has no control. In addition, although the Company owns a majority of
McCaw Brazil, the other shareholders have the ability to veto certain other
corporate actions. While the terms of the arrangements vary, the Company's
investments in the Operating Companies may be adversely affected in the event
that the Company's partners have economic or business interests or goals that
are inconsistent with those of the Company or take actions that are contrary to
the Company's policies or objectives. If certain Operating Companies that are
Restricted Group Members take actions that violate the covenants contained in
the Indenture, it may result in an event of default under the Indenture. See
"Description of the Notes." In addition, disagreements may arise between the
Company and any of its partners, which, in some cases, could lead to the Company
being required to purchase its partners' interest in the Operating Company.
 
     The Company may owe a fiduciary duty to the holders of various minority
interests in its subsidiaries. Accordingly, the Company may not have the right
to exercise unfettered control over such subsidiaries and may be required to
deal with such subsidiaries on terms no less favorable to such subsidiaries than
could be obtained from unaffiliated third parties. In addition, dividends or
other distributions paid or made by such subsidiaries must be paid or made on a
pro rata basis to all stockholders.
 
   
     GOVERNMENT REGULATION. The licensing, construction, ownership and operation
of wireless communications systems, and the grant, maintenance and renewal of
applicable licenses and radio frequency allocations, are regulated by
governmental entities in the markets in which the Company operates. In addition,
such matters and certain other aspects of wireless communications system
operations, including rates charged to customers and the resale of wireless
communications services, may be subject to public utility regulation in the
jurisdiction in which service is provided. Further, statutes and regulations in
certain of the markets in which the Company operates impose limitations on the
ownership of telecommunications companies by foreign entities. Changes in the
current regulatory environments in the countries in which the Company operates
or future judicial intervention, including with respect to interconnection
arrangements, requirements for increased capital investments, regulations
affecting prices the Company is able to charge for its services or foreign
ownership limitations, could have a material adverse effect on the Company. For
a more detailed description of the regulatory environment in each of the
countries in which the Operating Companies operate, see the "Regulatory and
Legal Overview" discussion for each Operating Company under "Business."
    
 
     Wireless communications licenses and spectrum allocations are subject to
ongoing review and, in some cases, to modification or early termination for
failure to comply with applicable regulations. Most of the Company's wireless
communications licenses have fixed terms and are not automatically renewable. In
cases where license terms are fixed, there can be no assurance that license
renewal will be effected, or if effected that renewal will be on acceptable
economic terms.
 
   
     Because of the uncertainty as to the interpretation of regulations in
certain jurisdictions, there can be no assurance the Company can provide planned
services in each jurisdiction and it may be possible that the Company may be
prohibited from providing services it intends to provide in the future in
certain jurisdictions, including ESMR services. See also "-- Possible Delay in
Offering ESMR Services in Brazil."
    
 
   
     Before McCaw Brazil can launch commercial iDEN-based ESMR services in
Brazil, it will need to obtain the following approvals from the Ministry of
Communications: (i) project installation approval; and (ii) post-installation
operating approval. In addition, before McCaw Brazil can commence ESMR service,
"type certifications" must be obtained from the Ministry of Communications with
respect to the equipment to be deployed in Brazil. Motorola has received type
certification for most of its iDEN equipment, however, the Nortel switch and the
subscriber units that are used with iDEN networks have not yet been type
certified. The
    
 
                                       21
<PAGE>   24
 
Company believes that it will receive these approvals on a timely basis. No
assurance can be given that the Ministry of Communications will grant the
approvals or that the Company's planned roll-out of ESMR will not be delayed.
 
   
     On April 26, 1997 and in the beginning of June 1997, news reports appeared
in the Brazilian newspapers and international wire services that an anonymous
source had forwarded to the Ministry of Communications a copy of the Company's
offering memorandum prepared in connection with the Initial Offering and a
letter alleging that the Company was operating in Brazil without authorization
from the Ministry of Communications. Based upon these allegations, the Ministry
of Communications sent the Company a letter requesting its comments to the
allegations and the Company sent the Ministry of Communications a letter
responding to such allegations. Further, certain members of the Brazilian
Congress introduced legislation that would eliminate the guaranteed right of SMR
providers to interconnect to the public telecommunications network. Such
legislation was enacted on July 16, 1997. Additionally, on May 15, 1997 and June
25, 1997, the Ministry of Communications issued proposed regulations for public
comment that, if approved as drafted, would impose limitations on the Company's
ability to (i) obtain direct telephone numbers for all of its subscriber units
in Brazil and (ii) interconnect with the public telecommunications network.
Although the Company believes that the current regulatory framework permits the
operation of its existing business in Brazil, the proposed regulations, if
enacted as drafted, may limit the Company's current and future operations in
Brazil. Furthermore, there can be no assurance that the Brazilian Congress or
the Ministry of Communications will not modify the existing regulatory
framework, or that the Ministry of Communications will not initiate
administrative proceedings, to impede the Company from providing the existing
SMR services or launch ESMR services.
    
 
   
     Compliance with the terms of the Operating Companies' licenses and certain
regulatory requirements, such as installation deadlines and minimum loading
requirements, can be difficult. There can be no assurance that such requirements
will be met or that the Company will not lose any applicable wireless
communications licenses as a result of its failure to meet such requirements.
The Company currently is not in compliance with applicable installation
deadlines and minimum loading requirements with respect to certain channels
located in various parts of Brazil outside Sao Paulo. Failure to comply with
such requirements may subject the licenses relating to such channels to
forfeiture by the Ministry of Communications. Requests for extensions of the
relevant deadlines in most of the major cities have been filed with the Ministry
of Communications; however, no responses have been received. There can be no
assurance that the Ministry of Communications will not take action in response
to such failure to comply that would have an adverse effect on McCaw Brazil.
Additionally, in June 1997, the Ministry of Communications ordered the Company
to discontinue the operation of two cell sites in the state of Sao Paulo based
on the Ministry's assertion that such sites were operating outside of the
geographical area covered by the Sao Paulo City license. Although the Company
believes that these cell sites are consistent with the applicable license, there
can be no assurance that the Ministry of Communications will agree with the
Company's interpretation of the area covered by the applicable license.
Additionally, because many of the regulatory frameworks are relatively new and
still developing in the countries in which the Company operates and the
enforcement of such regulations is often uncertain, it is difficult to determine
how regulators will interpret the rules or judge compliance, and what degree of
flexibility will be available.
    
 
   
     In Brazil, the transfer of control of an SMR licensee is subject to the
prior approval of the Ministry of Communications. Because of these license
transfer restrictions, McCaw Brazil's interest in 1,180 of its 1,700 channels is
structured pursuant to a number of option agreements entered into with the
shareholders of the respective corporate licensees of such channels (the "Option
Agreements"). Pursuant to the Option Agreements, McCaw Brazil has acquired a
minority interest in each such licensee not exceeding 49% and holds the option
to acquire the balance of the ownership interest in each such licensee upon the
payment of an option exercise price. The closing of each such option would be
conditioned upon securing the approval of the Ministry of Communications for the
transfer of control of the relevant licensees. The aggregate amount of the
exercise price if all the options are exercised is not material. A licensee is
not eligible to request approval for change of control until system installation
has been completed and approved by the Ministry of Communications, and many of
the channels subject to the Option Agreements have not been installed. While the
    
 
                                       22
<PAGE>   25
 
   
Company believes it will receive Ministry of Communications approval when it has
met the installation requirements, no assurance can be given that such approval
will be obtained. To the extent the Company is not able to exercise its option
to acquire the balance of the ownership interest in a particular licensee, the
Company believes that AirLink Service e Comercio Ltda. ("Airlink"), an indirect
wholly owned subsidiary of McCaw Brazil, would be able to continue to maintain
its existing contractual right to manage the operations subject to the license
held by such licensee pursuant to a service agreement and receive fees under
such service agreement. However, the Company would not own such licensee and the
Company's rights with respect to such license could be limited. There can be no
assurance that the Ministry of Communications would not challenge the validity
of such service agreements. All of McCaw Brazil's channels in Sao Paulo are
indirectly owned entirely by it and are not held pursuant to the Option
Agreements.
    
 
   
     The Company owns or has options to acquire licensees with multiple channels
in each of its service areas in Brazil, which have been acquired from private
parties rather than the Ministry of Communications. Under an administrative
ruling of the Ministry of Communications ("Administrative Ruling No. 478"), one
entity may not "receive" more than one SMR license in a given service area. Such
ruling also provides that an entity may not receive an SMR license if such
entity is a member of a commonly controlled or commonly managed group where
another member of such group already holds a license in the same service area.
The Company believes that Administrative Ruling No. 478 does not restrict an
entity from acquiring prior to July 13, 1994 more than one licensee in the same
service area from private parties and holding such licensee directly or
indirectly.
    
 
   
     Administrative Ruling No. 478 also is unclear as to whether, in the event
of a transfer of multiple licensees, it would be permissible to consolidate such
licensees under the ownership of one entity. In any event, the Company believes
that any limitation on acquiring or holding multiple SMR licensees in the same
service area or consolidation of multiple licensees would not affect those
licensees who held SMR licensees prior to July 13, 1994, the effective date of
Administrative Ruling No. 478. All of McCaw Brazil's licenses in Sao Paulo were
issued prior to July 13, 1994. There can be no assurance that the Ministry of
Communications will approve transfers of majority control of licensees in the
same service area. Furthermore, Decree No. 2197, effective April 4, 1997,
provides that any transfer of control can only occur after the period of time
established in the rules to be issued by the Ministry of Communications. Any
failure to approve such a transfer could have a material adverse effect on the
Company.
    
 
     In the Philippines, cellular mobile operators are required to install at
least 400,000 local exchange lines. The Company does not believe that Infocom is
subject to this requirement however no assurance can be given that this will be
the case. If this requirement were found to be applicable to Infocom, it would
require a significant capital investment.
 
   
     Each of the jurisdictions in which the Operating Companies operate permit
wireless communications companies to interconnect to the landline telephone
service provider in each market. Although interconnection services are currently
being provided in Brazil and Argentina, the Operating Companies in those
countries have not entered into definitive interconnection agreements with the
landline telephone service providers. The Company is currently negotiating
interconnection agreements to increase interconnect capacity in connection with
the upgrade to ESMR services in Brazil, Argentina and the Philippines. There can
be no assurance that interconnection agreements will be entered into or if
entered into or, whether such agreements will be on terms favorable to such
Operating Companies. The failure to enter into interconnection agreements on
favorable terms could have a material adverse effect on the Company's results of
operations. In many of the countries in which the Company operates,
telecommunications services are subject to value-added taxes.
    
 
   
     POSSIBLE DELAY IN OFFERING ESMR SERVICES IN BRAZIL. In June 1997 and July
1997, the Government of Brazil awarded Band B cellular licenses covering two of
the ten areas throughout Brazil, including the City of Sao Paulo, pursuant to
the rules governing the bidding process (the "Band B Rules"), which rules were
released by the Ministry of Communications on January 13, 1997. The Band B Rules
contain a provision which prohibits the initiation of operations by certain
other mobile telecommunications service providers in the areas covered by the
Band B licenses until December 31, 1999. It is unclear whether this provision of
the Band B Rules will prevent the Company from providing iDEN-based ESMR
services in Brazil before December 31, 1999. The Company does not believe that
the Band B Rules are applicable to its current SMR
    
 
                                       23
<PAGE>   26
 
operations in Brazil. There can be no assurance, however, that either the
Ministry of Communications or companies bidding for the Band B licenses will not
attempt to prevent the Company from offering ESMR services before December 31,
1999. In addition, companies bidding for the Band B licenses may request that
the December 31, 1999 date be extended or seek clarification as to the
applicability of the Band B Rules to iDEN-based ESMR services. Any significant
delay in offering ESMR services would have a material adverse effect on the
Company's competitive position in Brazil and on its business and results of
operations.
 
     TECHNOLOGY RISKS. In most of its markets, the Company plans to implement
ESMR networks using iDEN technology developed by Motorola. Prior to the second
quarter of 1996, Nextel, the principal user of iDEN technology, implemented its
ESMR networks using Motorola's "first generation" iDEN technology. Nextel
encountered certain system performance issues that resulted in a significant
postponement of its aggressive marketing efforts in the United States with
respect to its ESMR network utilizing iDEN technology, and particularly its
mobile telephone services. Nextel, together with Motorola, has pursued a
significant program directed toward the development and deployment of
modifications to the "first generation" iDEN technology platform designed
principally to produce improvements in audio quality for telephone interconnect
service. Although Nextel has deployed the modified iDEN technology successfully
in several of its markets to date, including Chicago, Detroit, Boston, Denver,
Atlanta, New York, Washington/Baltimore, Los Angeles, Northern California and
the Pacific Northwest, and has announced its intention to pursue an aggressive
roll-out of its ESMR networks in additional markets, its new systems have only
been in commercial use for a limited period and there can be no assurance that
the modified iDEN technology will satisfactorily continue to address the system
performance issues encountered in the deployment of the first generation
technology.
 
   
     COMPETITION. The Company's success will depend on the Operating Companies'
ability to compete effectively with other communications services providers,
including landline telephone companies and other wireless communications
companies, in the markets in which the Operating Companies offer services. Many
of the Company's competitors are well-established companies with substantially
greater financial and marketing resources, larger customer bases, and better
name recognition than the Company, and in certain markets may be able to provide
coverage to a larger number of subscribers. Because of their financial
resources, these competitors may be able to reduce prices in order to gain
market share. In Brazil, some of the largest telecommunications companies in the
world have been granted licenses in the on-going auctions to provide cellular
service, which will result in significant competition when those services are
launched. In addition, the Argentine and Mexican governments have announced
their intention to auction a number of licenses to provide wireless
communications service, and, as a result, the Company expects competition in
these countries to increase. The Company expects that the prices it charges for
its products and services will decline over the next few years as competition
intensifies in its markets. Because iDEN technology is not compatible with
cellular or PCS technology, the Company's customers will not be able to roam on
cellular or PCS systems. There can be no assurance that the Company will be able
to compete effectively in the future. For a more detailed description of the
competitive factors affecting each Operating Company, see the "Competition"
discussion for each Operating Company under "Business -- Operations and
Investments."
    
 
   
     On February 20, 1997, the Ministry of Communications released new SMR rules
(the "New SMR Rules") (i) permitting the combination of adjacent channels in
certain frequencies in the 400 MHz, 800 MHz and 900 MHz band and (ii) requiring
the use of digital technology for SMR systems operating in channels 401 to 600
of the 806-821 MHz and 851-866 MHz bands. The New SMR Rules also provide that
channels which have already been assigned to licensees, including the Company,
will be the object of a study addressing the prospective regrouping of such
channels for application in systems using digital technology. Because the New
SMR Rules allow SMR operators to combine adjacent channels to create contiguous
blocks and may provide for a regrouping of SMR channels to create more
contiguous blocks in the future, SMR operators may have additional technology
choices available to them. Although the Company does not believe that the New
SMR Rules will materially affect its technology decisions or the attractiveness
of McCaw Brazil's product or service offerings, the New SMR Rules and technology
decisions by other SMR operators, including existing and future competitors, may
increase competition in Brazil. The proposed regulations issued on May 15, 1997
and June 25, 1997, if enacted by the Ministry of Communications as
    
 
                                       24
<PAGE>   27
 
   
drafted, would impose limitations on the Company's ability to (i) obtain direct
telephone numbers for all of its subscriber units in Brazil and (ii)
interconnect with the public telecommunications network, and therefore, may
limit the Company's ability to compete effectively with other wireless
communications service providers in Brazil, including the operators of the Band
B cellular licenses.
    
 
     In addition, many existing telecommunications enterprises in the markets in
which the Company operates have successfully attracted significant investments
from multinational communications companies. These multinational communications
companies, which have invested in local landline, wireless communications and
paging entities, have substantially greater financial resources than the Company
and are attempting to accelerate the modernization of the telecommunications
sector in the regions in which they operate by bringing their operating and
financial resources to bear.
 
     The Company continuously reviews opportunities to acquire additional
licenses in new markets, primarily in emerging countries. In each new market,
the Company expects to face competition for such licenses from major
international telecommunications entities, as well as from local competitors.
 
     RAPID TECHNOLOGICAL CHANGES. The telecommunications industry is subject to
rapid and significant changes in technology, which could lead to new products
and services that compete with those offered by the Company or lower the cost of
current competing products and services to the point where the Company's
products and services could become noncompetitive, thereby requiring the Company
to reduce the prices of its services. While the Company is not aware of any
proposed changes that will materially affect the attractiveness of its product
and service offerings, the effect of technological changes on the Company's
businesses cannot be predicted. In the future, the Company expects to experience
competition from new technologies such as PCS and possibly satellite technology,
as well as from advances with respect to existing technologies such as ESMR,
cellular, paging and mobile data transmission. There can be no assurance that
the Company will be able to adopt new technologies or to keep pace with ongoing
advances in existing technology.
 
     RELIANCE ON LIMITED NUMBER OF EQUIPMENT SUPPLIERS. Motorola is expected to
provide most of the infrastructure and subscriber handset equipment to the
Company for its ESMR systems for the foreseeable future. It is expected that for
the first few years of the Company's ESMR operations, Motorola and competing
manufacturers who are licensed by Motorola (including Matsushita Communication
Industrial Co., Ltd., which has executed a definitive license agreement with
Motorola to employ Motorola's proprietary technology) will be the only
manufacturers of subscriber equipment that is compatible with the Company's ESMR
networks. In addition, the Company sources all of its switching equipment from
Nortel. Although the Company believes that it has or will be able to secure
contractual rights to procure sufficient equipment for its anticipated
requirements, there can be no assurance that such equipment will continue to be
available to the Company. Compania de Radiocomunicaciones Moviles S.A.,
operating under the name Movicom ("Movicom"), one of the two cellular service
providers in Argentina, has an agreement with Motorola pursuant to which
Motorola has agreed not to sell iDEN to any other operator in Argentina until
September 15, 1997. See "Business -- Operations and Investments -- Argentina."
 
     EXPANSION; MANAGEMENT OF GROWTH. The Company has experienced rapid growth
through acquisitions and intends to continue to grow through further expansion
and upgrade of its existing operations, through acquisitions and joint ventures
and through the establishment of new operations. The Company continually seeks
additional opportunities in its existing and new markets. The Company's future
success and its ability to meet its debt service obligations depends on the
expansion of its operations and development of a large subscriber base on a
timely basis.
 
     The Company's planned expansion projects will be subject to numerous risks,
any of which could require substantial changes to proposed plans or otherwise
alter the time frames or budgets currently contemplated. Such risks include (i)
securing the necessary channel grants and adhering to regulatory requirements
relating thereto; (ii) locating suitable sites for the Company's towers,
obtaining any required zoning variances or other governmental or local
regulatory approvals, and negotiating acceptable purchase, lease, joint venture
or other agreements; (iii) negotiating favorable interconnection agreements;
(iv) delays that may be caused by frequency cross-interference with other radio
spectrum users, such as television stations; and (v) risks
 
                                       25
<PAGE>   28
 
typically associated with any construction project, including possible shortages
of equipment or skilled labor, engineering or environmental problems, work
stoppages, weather interference and unanticipated cost increases. There can be
no assurance that the Company's currently planned expansion will be successful.
Moreover, numerous factors could cause the Company not to proceed with all or a
portion of its expansion plans or otherwise delay or alter its current expansion
plans.
 
     Once the Company's operations are in place in a particular market, the
Company's development of a significant subscriber base depends on the success of
its sales and marketing efforts and the receptiveness of the marketplace. In
most of its markets, the Company has limited experience in marketing its
wireless communications services and in tailoring its sales and marketing to
local conditions, and there can be no assurance that the Company's sales and
marketing teams will be able to successfully establish a large subscriber base
in its markets. In most of its markets, the Company will need to rely in part on
the efforts of independent dealers and distributors to market its services.
 
     As a result of the Company's aggressive expansion plans, the Company faces
significant challenges in managing its expanded operations. The Company must
hire and train a number of key personnel to manage its growth, and its expansion
plans will place substantial burdens on the Company's current management
resources, information systems and financial controls. The Company intends to
adopt a decentralized management strategy in each country in which it operates.
While the Company believes this decentralized approach will result in efficient
and effective operations, the management, information, internal control,
reporting and accounting issues involved in any decentralized organization can
be significant. In addition, the Company expects to face significant challenges
in integrating newly acquired businesses with its existing operations. There can
be no assurance that the Company will be able to manage its growth effectively.
Failure to do so would have a material adverse effect on the Company's results
of operations.
 
   
     CONTROL BY NEXTEL AND ITS SIGNIFICANT STOCKHOLDERS; CONFLICTS OF INTEREST;
DEPENDENCE ON NEXTEL. The Company is a wholly owned subsidiary of Nextel and
Nextel therefore has the power to elect all the directors of the Company. Of the
six directors that comprise the board of directors of the Company, four are also
directors and/or officers of Nextel. Nextel and directors and officers of Nextel
who are also directors of the Company are in positions that may result in
conflicts of interests with respect to transactions involving the Company. The
Company currently engages in and expects, in the future, to continue to engage
in transactions with Nextel and its affiliates. See "Certain Relationships and
Related Transactions."
    
 
     Based on securities ownership information relating to Nextel, and after
giving effect to the conversion of the outstanding shares of Nextel's preferred
stock and the exercise in full of outstanding options and warrants held by the
McCaw Investor and Motorola, the McCaw Investor and Motorola would beneficially
own approximately 26.3% and approximately 14.2% of the Nextel Class A Common
Stock, respectively, outstanding as of March 21, 1997. Pursuant to the
Securities Purchase Agreement dated as of April 4, 1995, as amended, among
Nextel, the McCaw Investor and Craig O. McCaw (the "McCaw Securities Purchase
Agreement"), the McCaw Investor has the right to designate not less than 25% of
the board of directors of Nextel (the "Nextel Board"). Additionally, the McCaw
Investor is effectively entitled to designate a majority of the members of the
Operations Committee (the "Operations Committee") of the Nextel Board and has
the authority to formulate key aspects of Nextel's business strategy. As a
result, the McCaw Investor is in a position to exert significant influence over
Nextel's, and thereby McCaw International's, affairs.
 
     Certain decisions concerning the operations or financial structure of the
Company may present conflicts of interest between Nextel as the owner of the
Company's capital stock and the Holders of the Notes. Nextel may have an
interest in pursuing acquisitions, divestitures, financings or other
transactions which, in its judgment, could enhance the value of its equity, even
though such transactions might involve risk to the Holders of the Notes.
 
     The Company and Nextel have entered into a right-of-first-opportunity
agreement (the "Non-Compete Agreement") effective as of the Closing Date of the
Initial Offering pursuant to which Nextel has agreed that neither Nextel nor any
Affiliate (as defined in the agreement) controlled by Nextel will in the future
participate in the ownership or operation of two-way terrestrial-based mobile
wireless communications systems ("Wireless Entities") anywhere other than in the
United States and Canada (for so long as Nextel owns an
 
                                       26
<PAGE>   29
 
equity interest in Clearnet) unless such opportunities ("Future Wireless
Opportunity") have first been presented to the Company. Such restriction will
not apply to, among other things, any commercial relationship with any Wireless
Entity (including channel or frequency sharing, roaming, purchase or sale of
goods or services, licensing of intellectual property or other intangible rights
or similar business related arrangement) that does not involve the directing or
participating in the management of such Wireless Entity. The Company has agreed
that, without the consent of Nextel, neither it, its Restricted Affiliates nor
any of its Unrestricted Affiliates (each as defined in the "Description of the
Notes") will participate in the ownership or management of any wireless
communications service business in the United States or Canada other than with
respect to its interest in Clearnet. Such restrictions terminate upon the
earliest to occur of (i) April 15, 2007 and (ii) the date on which a Change of
Control occurs (as defined in the "Description of the Notes").
 
     If Nextel gives the Company notice (the "Initial Notice") of a Future
Wireless Opportunity, the Company will have 60 days to notify Nextel that it
intends to pursue such opportunity and how it intends to finance its
participation. The Company must have secured a financing commitment within 90
days of the date of the Initial Notice and the Future Wireless Opportunity must
be consummated within nine months of the date of the Initial Notice. In the
event the Company fails to respond to Nextel within the 60 and 90 day time-
frames or fails to consummate the transaction within the nine-month period,
Nextel will be free to pursue the Future Wireless Opportunity.
 
     The Company has agreed not to amend the Non-Compete Agreement if such
amendment is material and adverse to the holders of the Notes or the Warrants
and to provide such holders with written notice 30 days prior to any amendment.
 
     Each of the McCaw Investor and Motorola has and (subject to the terms of
applicable agreements between such parties and Nextel) may have an investment or
interest in entities that provide wireless communications services that could
potentially compete with Nextel and the Company. Under the McCaw Securities
Purchase Agreement, the McCaw Investor, Craig O. McCaw and their Controlled
Affiliates (as defined in the McCaw Securities Purchase Agreement) may not, for
a period of time, participate in other two-way terrestrial-based mobile wireless
communications systems in the region that includes any part of North America or
South America unless such opportunities have first been presented to and
rejected by Nextel. Such restrictions terminate on the later to occur of July
28, 2000 and one year after the termination of the Operations Committee.
 
     The Company also depends on Nextel to provide it with various services
including technology assistance, as well as certain administrative services.
Such services are provided on a cost-basis pursuant to an overhead services
agreement. See "Certain Relationships and Related Transactions."
 
   
     In November 1996, Nextel, McCaw International and Motorola entered into a
binding memorandum of understanding regarding the Motorola Financing (the
"Motorola MOU"). Under the Motorola MOU, Motorola agreed to provide an aggregate
of $400 million in vendor financing to Nextel and McCaw International for the
worldwide purchase of iDEN equipment and services and ancillary products (such
as switches). In March 1997, Motorola and Nextel entered into a term sheet
increasing the maximum worldwide vendor financing available to Nextel and McCaw
International to $650 million, with a maximum non-U.S. amount outstanding of
$400 million, subject to certain per country limits as agreed in the Motorola
MOU. The Motorola MOU sets a limit of $125 million per country (other than the
United States and Canada) on the amount that may be borrowed under the Motorola
Financing. Nextel, McCaw International and Motorola agreed to an initial
commitment to McCaw Brazil, McCaw Argentina and Infocom under the Motorola
Financing of $125 million, $81 million and $15 million, respectively.
Commitments provided by Motorola to provide financing to any Operating Company
count 100% against Motorola's $650 million aggregate commitment. Currently,
Motorola has not committed any financing for Mexico. The Motorola MOU
contemplates that the loans under the Motorola Financing will bear interest at a
rate of 2% to 4% over prime rate, depending on the Operating Company placing the
order and the country in which such company is installing the iDEN equipment and
is likely to have a maturity of up to six years. Borrowings by an Operating
Company will be secured by all the assets and stock of such Operating Company
and it is expected that the Company will guarantee such borrowings on a pro rata
basis based on the equity interest of such Operating
    
 
                                       27
<PAGE>   30
 
Company owned by the Company (with the exception of Brazil where the Company
will be required to guarantee 100% of such borrowings).
 
     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 March 31, 1997, Nextel had borrowed $110
million pursuant to the Motorola Financing. Accordingly, there can be no
assurance that more than $95 million of the Motorola Financing will be available
to fund the Operating Companies' equipment purchases. 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, McCaw 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.
 
     Nextel has provided a substantial amount of financing to the Company, but
it is under no obligation to do so in the future.
 
   
     DEPENDENCE ON KEY PERSONNEL. The success of the Company and its growth
strategy depends in large part on the Company's ability to attract and retain
key management, marketing, finance and operating personnel, both at the Company
and the Operating Companies. In many of the countries in which the Company
operates, experienced management and other highly skilled personnel are in great
demand. There can be no assurance that the Company will continue to attract and
retain the qualified personnel necessary for its business. In addition, the loss
of the services of one or more members of its senior management team, in
particular Keith D. Grinstein, the Company's President and Chief Executive
Officer, could have a material adverse effect on the Company. The Company does
not maintain key person life insurance.
    
 
     RISKS ASSOCIATED WITH EMERGING MARKETS; UNCERTAINTIES ASSOCIATED WITH A NEW
INDUSTRY. Most of the Company's markets are considered to be "emerging markets."
Although political, economic and social conditions differ in each country in
which the Company currently operates, developments in one country may affect the
market value and liquidity of the Notes, Warrants and Warrant Shares and the
Company's access to international capital markets. The Company currently does
not have political risk insurance in the countries in which it conducts
business.
 
     The success of the Company's operating strategies is subject to factors
that are beyond the Company's control and impossible to predict due, in part, to
the limited history of wireless communications services in the Company's
existing and targeted markets. Consequently, the size of these markets for
wireless communications services, the rates of penetration of these markets, the
sensitivity and ability of potential subscribers to pay subscription and other
fees, the extent and nature of the competitive environment and the immediate and
long-term viability of wireless communications services in these markets are
uncertain.
 
     CURRENCY RISKS AND EXCHANGE CONTROLS. All of the Company's revenues will be
denominated in non-U.S. currencies, although a significant portion of its
capital and operating expenditures, including imported infrastructure equipment,
and the interest expense on the Notes and under the Motorola Financing, will be
denominated in U.S. dollars. Fluctuations in exchange rates relative to the U.S.
dollar may have a material adverse effect on the Company's earnings or assets.
To the extent the Operating Companies distribute dividends in local currencies
in the future, the amount of cash to be received by the Company will be affected
by fluctuations in exchange rates. In addition, certain of the countries in
which the Company has operations restrict the expatriation or conversion of
currency.
 
     LOCAL ECONOMIES; POTENTIAL INFLATION. The Company's operations depend on
the economies of the markets in which it has interests. These markets are in
countries with economies in various stages of development or structural reform,
some of which are subject to rapid fluctuations in terms of consumer prices,
 
                                       28
<PAGE>   31
 
employment levels, gross domestic product and interest and foreign exchange
rates. The Company may be subject to such fluctuation in the local economies. To
the extent such fluctuations have an effect on the ability of customers to pay
for the Operating Companies' services, the growth of the Company's wireless
services could be impacted negatively. Many of the countries in which the
Company operates do not have established credit bureaus, thereby making it more
difficult for the Company to ascertain the creditworthiness of potential
customers. Accordingly, the Company may experience a higher level of bad debt
expense than otherwise would be the case. In particular, the Company's bad debt
expense as a percentage of revenues in Brazil and Mexico has been significantly
higher than in the Company's other markets.
 
     Certain of the Operating Companies operate in countries in which the rate
of inflation is significantly higher than that of the United States. There can
be no assurance that any significant increase in the rate of inflation in such
countries could be offset, in whole or in part, by corresponding price increases
by the Operating Companies, even over the long term.
 
     IMPORT DUTIES ON NETWORK EQUIPMENT AND HANDSETS. The Company's operations
are highly dependent upon the successful and cost-efficient importation of
infrastructure equipment and handsets from North America and, to a lesser
extent, Europe and Japan. In the countries in which the Company operates,
network equipment and handsets are subject to significant import duties and
other taxes that can be as high as 50%. Although the Company believes there is a
trend away from increased import duties, any significant increase in the future
could have a material adverse effect on the Company's results of operations.
 
     INTERNATIONAL TAX RISKS. Distributions of earnings and other payments
(including interest) received from the Company's operating subsidiaries and
affiliates may be subject to withholding taxes imposed by the jurisdictions in
which such entities are formed or operating, which will reduce the amount of
after-tax cash the Company can receive from the Operating Companies. In general,
a U.S. corporation may claim a foreign tax credit against its federal income tax
expense for such foreign withholding taxes and for foreign income taxes paid
directly by foreign corporate entities in which the Company owns 10% or more of
the voting stock. The ability to claim such foreign tax credits and to utilize
net foreign losses is, however, subject to numerous limitations, and the Company
may incur incremental tax costs as a result of these limitations or because the
Company is not in a tax-paying position in the United States.
 
     The Company may also be required to include in its income for U.S. federal
income tax purposes its proportionate share of certain earnings of those foreign
corporate subsidiaries that are classified as "controlled foreign corporations"
without regard to whether distributions have been actually received from such
subsidiaries.
 
     LEGAL ENFORCEMENT. A number of the agreements the Company enters into with
the Operating Companies are governed by the laws of, and are subject to dispute
resolution in the courts of, or through arbitration proceedings in, the country
or region in which the operation is located. The Company cannot accurately
predict whether such forum will provide it with an effective and efficient means
of resolving disputes that may arise in the future. Even if the Company is able
to obtain a satisfactory decision through arbitration or a court proceeding, it
could have difficulty enforcing any award or judgment on a timely basis. The
Company's ability to obtain or enforce relief in the United States is uncertain.
 
     ORIGINAL ISSUE DISCOUNT CONSEQUENCES. The Private Notes were issued with
original issue discount for U.S. federal income tax purposes. The Exchange Notes
should be treated as a continuation of the Private Notes. Consequently, Holders
of the Exchange Notes generally will be required to include amounts in gross
income for U.S. federal income tax purposes in advance of receipt of the cash
payments to which the income is attributable. The Exchange Notes may be subject
to the high-yield discount obligation rules, which will defer and may, in part,
eliminate the Company's ability to deduct for U.S. federal income tax purposes
the original issue discount attributable to the Exchange Notes. Accordingly, the
Company's after-tax cash flow might be less than if the original issue discount
on the Exchange Notes was deductible when it accrued. See "Certain U.S. Federal
Income Tax Considerations" for a more detailed discussion of the U.S. federal
income tax consequences resulting from the Exchange Offer.
 
                                       29
<PAGE>   32
 
     If a bankruptcy case is commenced by or against the Company under the U.S.
Bankruptcy Code after the issuance of the Notes, the claim of a Holder with
respect to the principal amount thereof may be limited to an amount equal to the
sum of (i) the initial offering price and (ii) that portion of the original
issue discount that is not deemed to constitute "unmatured interest" for
purposes of the U.S. Bankruptcy Code. Any original issue discount that was not
amortized as of any such bankruptcy filing would constitute "unmatured
interest."
 
     FOREIGN CORRUPT PRACTICES ACT. As a domestic corporation and a wholly owned
subsidiary of Nextel, the Company is subject to the Foreign Corrupt Practices
Act (the "FCPA"), which generally prohibits U.S. companies and their
intermediaries from bribing foreign officials for the purpose of obtaining or
keeping business. Although the Company has taken precautions to comply with the
FCPA, there can be no assurance that such precautions will protect the Company
against liability under the FCPA, particularly as a result of actions which may
in the past have been taken or which may be taken in the future by agents and
other intermediaries for whom the Company may have exposure under the FCPA. In
particular, the Company may be held responsible for actions taken by its local
partners even though the Company has no ability to control them. Any
determination that the Company had violated the FCPA could have a material
adverse effect on the Company.
 
     RADIO FREQUENCY EMISSION CONCERNS. Allegations have been made, but not
proven, that the use of portable mobile communications devices may pose health
risks due to radio frequency emissions from such devices. Studies performed by
wireless telephone equipment manufacturers have rebutted these allegations, and
a major industry trade association and certain governmental agencies have stated
publicly that the use of such phones poses no undue health risk. Certain
consumers have alleged that serious health risks have resulted from the use of
certain mobile communications devices. The actual or perceived health risks of
mobile communications devices could adversely affect mobile communications
services providers, including the Company, through reduced subscriber growth,
reduced network usage, the threat of product liability suits or limitations on
financing available to the mobile communications industry.
 
     LACK OF PUBLIC MARKET. The NASD has designated the Private Notes as
securities eligible for trading in the PORTAL market of the NASD. However, the
Exchange Notes are new securities for which there is currently no active trading
market. The Company does not intend to list the Exchange Notes on any national
securities exchange or to seek the admission thereof to trading in the Nasdaq
National Market System and there can be no assurance as to the development of
any market or liquidity of any market that may develop for the Exchange Notes.
If a market for the Exchange Notes does develop, the price of such Exchange
Notes may fluctuate and liquidity may be limited. If a market for the Exchange
Notes does not develop, purchasers may be unable to resell such Exchange Notes
for an extended period of time, if at all. Historically, the market for
non-investment grade debt has been subject to disruptions that have caused
substantial volatility in the prices of securities similar to the Exchange
Notes. There can be no assurance that, if a market for the Exchange Notes were
to develop, such market would not be subject to similar disruptions.
 
     FAILURE TO EXCHANGE PRIVATE NOTES. The Exchange Notes will be issued in
exchange for Private Notes only after timely receipt by the Exchange Agent of
such Private Notes, a properly completed and duly executed Letter of Transmittal
and all other required documentation. Therefore, holders of Private Notes
desiring to tender such Private Notes in exchange for Exchange Notes should
allow sufficient time to ensure timely delivery. Neither the Exchange Agent nor
the Company are under any duty to give notification of defects or irregularities
with respect to tenders of Private Notes for exchange. Private Notes that are
not tendered or are tendered but not accepted will, following consummation of
the Exchange Offer, continue to be subject to the existing restrictions upon
transfer thereof. In addition, any holder of Private Notes who tenders in the
Exchange Offer for the purpose of participating in a distribution of the
Exchange Notes will be required to comply with the registration and prospectus
delivery requirements of the Securities Act in connection with any resale
transaction. Each broker-dealer who holds Private Notes acquired for its own
account as a result of market making or other trading activities and who
receives Exchange Notes for its own account in exchange for such Private Notes
pursuant to the Exchange Offer, must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Notes. To the extent
that Private Notes are tendered and accepted in the Exchange Offer, the trading
market for untendered and tendered but unaccepted Private Notes could be
adversely affected due to the limited amount, or "float," of the Private Notes
that are expected
 
                                       30
<PAGE>   33
 
to remain outstanding following the Exchange Offer. Generally, a lower "float"
of a security could result in less demand to purchase such security and could,
therefore, result in lower prices for such security. For the same reason, to the
extent that a large amount of Private Notes are not tendered or are tendered and
not accepted in the Exchange Offer, the trading market for the Exchange Notes

                                  THE COMPANY
 
     McCaw International was founded in February 1995 by Craig O. McCaw to
invest in and manage international wireless communications operations. In August
1995, a wholly owned subsidiary of Nextel purchased all the outstanding shares
of the Company from Craig O. McCaw, who was at the time and remains, a
significant shareholder of Nextel.
 
   
     The chart below sets forth the summary of the corporate ownership structure
of the Company and the Operating Companies as of April 30, 1997.
    
 
                                   [CHART]

- ---------------
(1) After giving effect to the Argentina Transaction. Under U.S. GAAP in effect
    on the date hereof, McCaw Argentina will be accounted for under the equity
    method. Prior to the consummation of the Argentina Transaction, the Company
    owned 100% of McCaw Argentina S.A., an Argentine corporation ("McCaw
    Argentina S.A."), which became a subsidiary of McCaw Argentina upon
    consummation of the Argentina Transaction.
 
   
(2) On June 30, 1997, the Company increased its interest to 48.1% by purchasing
    all of the shares of Mobilcom held by a then-current shareholder.
    
 
   
(3) Represents the right to receive 25.2% of the profits generated by the
    Shanghai GSM System.
    
 
   
     Brazil. On January 30, 1997, Nextel acquired an 81% equity interest in
McCaw Brazil for a purchase price of $186.3 million, which was paid with Nextel
Class A Common Stock, and simultaneously contributed its equity interest in
McCaw Brazil to the Company. McCaw Brazil commenced commercial operations in
October 1994 and grew quickly through a series of acquisitions of Brazilian SMR
license-holding companies. McCaw Brazil is currently the largest SMR operator in
Brazil both in terms of the number of channels and the number of subscribers in
its licensed service areas. McCaw Brazil owns or has options to purchase
licenses for 1,700 SMR channels in Brazil, including 195 in Sao Paulo
(representing 9.75 MHz) and 160 in Rio de Janeiro (representing 8.0 MHz). These
licenses cover more than 59 million POPs, including the 10 largest cities in
Brazil. McCaw Brazil currently offers SMR services in 27 cities, including Sao
Paulo, Rio de Janeiro, Belo Horizonte, Brasilia, Porto Alegre and Curitiba.
    
 
     Telcom Ventures, LLC ("Telcom Ventures") and certain other entities
(together the "Telcom Group") own the remaining 19% equity interest in McCaw
Brazil. Telcom Ventures is the indirect majority shareholder of LCC
International, Inc., a leading wireless engineering consulting services firm,
and is owned by the family of Dr. Rajendra Singh and affiliates of the Carlyle
Group, a United States based principal investment firm.
 
                                       32
<PAGE>   35
 
   
     The Company is currently in discussions with several large Brazilian
corporate groups regarding the possible sale of up to a 15% equity interest in
the Brazil Holding Company. The proceeds from the Brazil Equity Sale will be
applied to the build-out of McCaw Brazil's ESMR network. There can be no
assurance that the Company will be able to consummate any such transaction.
    
 
   
     Argentina. In 1995, McCaw Argentina S.A. (formerly known as Com Control
Comunicacion Controlada, S.A.) purchased and obtained a license to operate 100
SMR channels in each of Buenos Aires, Cordoba, Rosario and Mendoza, the four
largest cities in Argentina. McCaw Argentina S.A. commenced commercial SMR
operations in February 1997. Following the Argentina Transaction, McCaw
Argentina became the largest SMR channel holder in Argentina, with twice as many
SMR channels as the second largest SMR operator. McCaw Argentina has 180 SMR
channels (9 MHz) in Buenos Aires, 200 SMR channels (10 MHz) in each of the three
other major cities and 20 additional SMR channels in each of Mar del Plata and
Tucuman. The Company's licenses cover over 17.6 million POPs. As part of the
Argentina Transaction, McCaw Argentina became the holder of a nationwide paging
business with approximately 4,000 subscribers. The Company and WVA each own 50%
of McCaw Argentina.
    
 
   
     Mexico. Mobilcom was formed in 1993 by an affiliate of Grupo Comunicaciones
San Luis S.A. de C.V. ("Grupo San Luis") to pursue SMR opportunities in Mexico
and began commercial operations in September 1993. In March 1995, Nextel made
its first investment in Mobilcom by purchasing a 16.5% equity interest. During
the last two years, through a series of transactions, Nextel increased its
ownership interest in Mobilcom, as well as its involvement in the management of
Mobilcom and currently has the right to nominate a majority of the board of
directors of Mobilcom. The Company must invest substantial additional amounts in
Mobilcom to maintain such right. The Company currently owns a 48.1% equity
interest in Mobilcom. See "Risk Factors -- Contingent Capital Requirements."
    
 
     Mobilcom is the leading SMR provider in Mexico and offers, through its
subsidiaries and management agreements, SMR services throughout Mexico,
including in its three largest cities, and along a number of important highways.
The cities in which Mobilcom holds SMR licenses include Mexico City (with a
total of 204 channels representing approximately 10 MHz), Guadalajara (with a
total of 60 channels representing approximately 3 MHz) and Monterrey (with a
total of 25 channels representing approximately 1.25 MHz). The Company's
licenses cover over 42 million POPs.
 
   
     The Company's strategic partners in Mobilcom include Grupo San Luis, which
currently owns 21% of Mobilcom, Wireless Ventures of Mexico, Inc. ("WVM"), a
wholly owned subsidiary of Telcom Ventures, which owns approximately 11.6% and
Associated SMR, Inc. ("Associated SMR"), an international operator of wireless
communications systems, which owns approximately 11.3%. The Company has options
to acquire up to an additional 29.5% of Mobilcom, which expire on March 3, 1998.
    
 
     Philippines. In August 1996, McCaw International acquired a 30% equity
interest in Infocom. Infocom owns nationwide licenses (with a total of 100
channels representing approximately 5 MHz), covering more than 67 million POPs,
to provide SMR, ESMR and paging services. Infocom began commercial service of
its paging network in February 1995 under the brand name "Infopage" and plans to
launch commercial iDEN-based ESMR services by the end of 1997.
 
     The Company's partners in Infocom include the Gotesco Group, a leading
diversified conglomerate engaged in retail, real estate, banking, manufacturing
and trading in the Philippines headed by Jose C. Go, which owns a 20% interest
in Infocom. Affiliates of American International Group Inc. (collectively "AIG")
recently purchased a 10% interest in Infocom from an existing Infocom
shareholder at a significantly higher implied valuation than that paid by the
Company for its interest in Infocom. Other shareholders include a 32% holder and
an 8% holder.
 
   
     Shanghai. The Company has a contractual right to receive 25.2% of the
profits generated by the Shanghai GSM System operated by China United
Telecommunications, Ltd. ("Unicom") through its Shanghai branch ("Shanghai
Unicom"). The Company's interest in the Shanghai GSM System is held through its
60% equity interest in a Chinese joint venture, Shanghai McCaw
Telecommunications Co. Ltd. ("Shanghai McCaw"). Shanghai McCaw participates in
the Shanghai GSM System through a profit-sharing arrangement (the
    
 
                                       33
<PAGE>   36
 
"Unicom Agreement") between Unicom and Shanghai Science & Technology Investment
Corp. Ltd. ("SSTIC"), the Company's 40% partner in Shanghai McCaw. SSTIC is also
a shareholder of Unicom. The Shanghai GSM System covers the greater Shanghai
area, which is comprised of more than 14 million POPs. The Company's interest in
the Shanghai GSM System has been structured as a profit-sharing arrangement
because current Chinese laws prohibit a foreign party from direct participation
in the ownership and operation of telecommunications systems. The Company made
its investment in Shanghai McCaw in 1995. In addition to its equity investment,
the Company loaned Shanghai McCaw a portion of the funds necessary to fund the
Shanghai GSM System. At December 31, 1996, the outstanding balance of this loan
was $10.5 million. On March 29, 1997, the arrangements under the Unicom
Agreement were modified pursuant to the China Unicom Shanghai GSM Phase III
Cooperation Agreement (the "Phase III Agreement") between Unicom and Shanghai
McCaw. The Phase III Agreement requires Shanghai McCaw to provide 60% of the
funds required to expand the Shanghai GSM System. The profit sharing
arrangements under the Unicom Agreement were retained for a period until the
date the 50,001st subscriber is activated and are, thereafter, subject to change
as provided in the Phase III Agreement. See "Business -- Operations and
Investments -- Corporate Governance -- China."
 
     Unicom was established in 1994 by the Ministry of Electronics Industry, the
Ministry of Railways, the Ministry of Power and 13 other shareholders including
SSTIC. SSTIC is an investment holding company established by the Municipal
Government of Shanghai, six major Shanghai banks as well as two major
diversified Shanghai conglomerates for the purpose of developing the Shanghai
high-technology industry.
 
   
     Canada. The Company owns 1,596,067 shares of common stock of Clearnet, a
Nasdaq-listed company, representing approximately 3.7% of the outstanding common
stock of Clearnet. On June 30, 1997 the Company's Clearnet common stock had a
market value of approximately $19 million. Clearnet is the largest SMR operator
in Canada as measured by the number of current subscribers, the number of 800
MHz channels and the number of POPs it covers. Additionally, Clearnet holds one
of the two national 30 MHz licenses to provide PCS in Canada. Clearnet currently
offers SMR services in more than 40 cities throughout Canada and ESMR services
in Ontario and Quebec. Clearnet plans to launch its PCS network in Canada's
largest urban centers in mid-1997. The Company has one representative on
Clearnet's board of directors.
    
 
     Nextel made its initial investment in Clearnet in October 1994. The shares
of Clearnet contributed to the Company by NIC were the maximum number of shares
Nextel was permitted to transfer under certain agreements relating to its
indebtedness. Nextel continues to hold approximately 15.6% of Clearnet and also
has one representative on the board of directors of Clearnet.
 
   
     On June 26, 1997, Nextel announced that it received the consent of the
holders of its public notes regarding certain amendments to the indentures
governing such notes. The Nextel noteholders agreed, among other things, to
permit Nextel to transfer its equity interest in Clearnet to McCaw
International. If Nextel effects such transfer, McCaw International will hold an
aggregate of 8,373,845 shares of Clearnet, representing approximately 19% of the
outstanding common stock of Clearnet, which represents a 1.7% voting interest.
As of June 30, 1997, based on the closing price of Clearnet stock on the Nasdaq
Stock Market, Nextel's equity interest in Clearnet had a market value of
approximately $82 million. Although Nextel is permitted to transfer its interest
in Clearnet to the Company, there can be no assurance that Nextel will effect
such transfer or, should such transfer occur, that the market value of Nextel's
equity interest in Clearnet on the date of any such transfer will not be less
than the market value of such equity interest as of June 30, 1997.
    
 
   
     Nextel Investment Company. On February 28, 1997, NIC was merged with an
indirect wholly owned subsidiary of the Company, with NIC as the surviving
corporation. Prior to the consummation of the merger, NIC held approximately 38%
of Mobilcom, 3.7% of Clearnet, a note receivable related to Mobilcom and cash
and short-term investments at December 31, 1996 of $52.9 million. Prior to
consummation of the merger, the cash and short-term investments were distributed
to Nextel.
    
 
     The Company's principal executive and administrative offices are located at
1191 Second Avenue, Suite 1600, Seattle, Washington 98101 and its telephone
number at that location is (206) 749-8000.

                               THE EXCHANGE OFFER
 
PURPOSE OF THE EXCHANGE OFFER
 
     The Private Notes were sold by the Company on the Closing Date to the
Placement Agents pursuant to the Placement Agreement. The Placement Agents
subsequently sold the Private Notes to (i) "qualified institutional buyers"
("QIBs"), as defined in Rule 144A under the Securities Act ("Rule 144A"), in
reliance on Rule 144A, (ii) other investors in offshore transactions in reliance
on Regulation S under the Securities Act and (iii) a limited number of
institutional "accredited investors", as defined in Rule 501(a)(1), (2), (3) or
(7) under the Securities Act. As a condition to the sale of the Private Notes,
the Company and the Placement Agents entered into the Registration Rights
Agreement on March 3, 1997. Pursuant to the Registration Rights Agreement, the
Company agreed that (i) it would use its bests efforts to cause to be filed with
the Commission within 60 days after the Closing Date an exchange offer
registration statement under the Securities Act with respect to the Exchange
Notes, (ii) to cause such Registration Statement to remain effective under the
Securities Act until the closing of the Exchange Offer and (iii) it would use
its best efforts to have the Exchange Offer consummated not later than 60 days
after the effective date of the Registration Statement. The Company agreed to
issue and exchange Exchange Notes for all Private Notes validly tendered and not
withdrawn before the Expiration Date of the Exchange Offer. A copy of the
Registration Rights Agreement has been filed as an exhibit to the Registration
Statement of which this Prospectus is a part. The Registration Statement is
intended to satisfy the Company's obligations under the Registration Rights
Agreement.

TERMS OF THE EXCHANGE OFFER
 
     Upon the terms and subject to the conditions set forth in this Prospectus
and in the Letter of Transmittal, the Company will accept any and all Private
Notes validly tendered and not withdrawn prior to the Expiration Date.
 
     The Company will issue Exchange Notes in exchange for an equal aggregate
principal amount at maturity of outstanding Private Notes validly tendered
pursuant to the Exchange Offer and not withdrawn prior to the Expiration Date.
Private Notes may be tendered only in integral multiples of $1,000 principal
amount at maturity.
 
     The form and terms of the Exchange Notes are the same as the form and terms
of the Private Notes except that (i) the exchange will be registered under the
Securities Act and, therefore, the Exchange Notes will not bear legends
restricting the transfer thereof and (ii) holders of the Exchange Notes will not
be entitled to any of the registration rights of holders of Private Notes under
the Registration Rights Agreement, which rights will terminate upon the
consummation of the Exchange Offer. The Exchange Notes will evidence the same
indebtedness as the Private Notes (which they replace) and will be issued under,
and be entitled to the benefits of, the Indenture, which also authorized the
issuance of the Private Notes, such that both series of Notes will be treated as
a single class of debt securities under the Indenture.
 
     As of the date of this Prospectus, approximately $951.5 million in
aggregate principal amount at maturity of the Private Notes was outstanding.
Only a registered holder of the Private Notes (or such holder's legal
representative or attorney-in-fact), as reflected on the records of the Trustee
under the Indenture may participate in the Exchange Offer. Solely for reasons of
administration, the Company has fixed the close of business on          , 1997
as the record date for the Exchange Offer for purposes of determining the
persons to whom this Prospectus and the Letter of Transmittal will be mailed
initially. There will be no fixed record date for determining registered holders
of the Private Notes entitled to participate in the Exchange Offer.
 
     Holders of the Private Notes do not have any appraisal or dissenters'
rights under the Washington Business Corporation Act Law or the Indenture in
connection with the Exchange Offer. The Company intends to conduct the Exchange
Offer in accordance with the provisions of the Registration Rights Agreement and
the applicable requirements of the Securities Act and the rules and regulations
of the Commission thereunder.
 
     The Company shall be deemed to have accepted validly tendered Private Notes
when, and if, the Company has given oral or written notice thereof to the
Exchange Agent. The Exchange Agent will act as agent for the tendering holders
of Private Notes for the purposes of receiving the Exchange Notes from the
Company.
 
     Holders who tender Private Notes in the Exchange Offer will not be required
to pay brokerage commissions or fees or, subject to the instructions in the
Letter of Transmittal, transfer taxes with respect to the exchange of Private
Notes pursuant to the Exchange Offer. The Company will pay all charges and
expenses, other than certain applicable taxes described below, in connection
with the Exchange Offer. See "-- Fees and Expenses."
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
     The term "Expiration Date" shall mean 5:00 p.m., New York City time on
         , 1997, unless the Company, in its sole discretion, extends the
Exchange Offer, in which case the term "Expiration Date" shall mean the latest
date and time to which the Exchange Offer is extended.
 
     In order to extend the Exchange Offer, the Company will notify the Exchange
Agent of any extension by oral or written notice and mail to the registered
holders an announcement thereof, each prior to 9:00 a.m., New York City time, on
the next business day after the previously scheduled Expiration Date.
 
     The Company reserves the right, in its sole discretion, (i) to delay
accepting any Private Notes, (ii) to extend the Exchange Offer or (iii) if, in
the opinion of counsel for the Company, the consummation of the Exchange Offer
would violate any applicable law, rule or regulation or any applicable
interpretation of the staff of the Commission, to terminate or amend the
Exchange Offer by giving oral or written notice of such delay,
 
                                       37
<PAGE>   40
 
extension, termination or amendment to the Exchange Agent. Any such delay in
acceptance, extension, termination or amendment will be followed as promptly as
practicable by oral or written notice thereof to the registered holders. If the
Exchange Offer is amended in a manner determined by the Company to constitute a
material change, the Company will promptly disclose such amendment by means of a
prospectus supplement that will be distributed to the registered holders, and
the Company will extend the Exchange Offer for a period of five to ten business
days, depending upon the significance of the amendment and the manner of
disclosure to the registered holders, if the Exchange Offer would otherwise
expire during such five to ten business day period.
 
     Without limiting the manner in which the Company may choose to make a
public announcement of any delay, extension, amendment or termination of the
Exchange Offer, the Company shall have no obligation to publish, advertise, or
otherwise communicate any such public announcement, other than by making a
timely release to an appropriate news agency.
 
INTEREST ON THE EXCHANGE NOTES
 
     The Exchange Notes will not bear interest prior to April 15, 2002. From and
after April 15, 2002, the Private Notes bear interest and the Exchange Notes
will bear interest, which will be payable in cash, at a rate of 13% per annum,
on each April 15 and October 15, commencing October 15, 2002 to holders of
record on the immediately preceding April 1 and October 1, respectively.
 
RESALE OF THE EXCHANGE NOTES
 
     With respect to the Exchange Notes, based upon interpretations by the staff
of the Commission set forth in certain no-action letters issued to third
parties, the Company believes that a holder who exchanges Private Notes for
Exchange Notes in the ordinary course of business, who is not participating,
does not intend to participate, and has no arrangement with any person to
participate in a distribution of the Exchange Notes, and who is not an
"affiliate" of the Company within the meaning of Rule 405 of the Securities Act,
will be allowed to resell Exchange Notes to the public without further
registration under the Securities Act and without delivering to the purchasers
of the Exchange Notes a prospectus that satisfies the requirements of Section 10
of the Securities Act. However, if any holder acquires Exchange Notes in the
Exchange Offer for the purpose of distributing or participating in the
distribution of the Exchange Notes, such holder cannot rely on the position of
the staff of the Commission enumerated in certain no-action letters issued to
third parties and must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with any resale transaction,
unless an exemption from registration is otherwise available. Each broker-dealer
that receives Exchange Notes for its own account in exchange for Private Notes
acquired by such broker-dealer as a result of market-making or other trading
activities must acknowledge that it will deliver a prospectus in connection with
any resale of Exchange Notes. The Letter of Transmittal states that by so
acknowledging and by delivering a prospectus, a broker-dealer will not be deemed
to admit that it is an "underwriter" within the meaning of the Securities Act.
This Prospectus, as it may be amended or supplemented from time to time, may be
used by a broker-dealer in connection with resales of any Exchange Notes
received in exchange for Private Notes acquired by such broker-dealer as a
result of market-making or other trading activities. Pursuant to the
Registration Rights Agreement, the Company has agreed to make this Prospectus,
as it may be amended or supplemented from time to time, available to any such
broker-dealer that requests copies of such Prospectus in the Letter of
Transmittal for use in connection with any such resale for a period not to
exceed 180 days after the closing of the Exchange Offer. See "Plan of
Distribution."
 
PROCEDURES FOR TENDERING
 
     Only a registered holder of Private Notes may tender such Private Notes in
the Exchange Offer. To tender in the Exchange Offer, a holder of Private Notes
must complete, sign and date the Letter of Transmittal, or a facsimile thereof,
have the signatures thereon guaranteed if required by the Letter of Transmittal,
and mail or otherwise deliver such Letter of Transmittal or such facsimile to
the Exchange Agent at the address set forth below under "-- Exchange Agent" for
receipt prior to the Expiration Date. In addition, either (i) certificates for
such Private Notes must be received by the Exchange Agent along with the Letter
of
 
                                       38
<PAGE>   41
 
Transmittal, (ii) a timely confirmation of a book-entry transfer (a "Book-Entry
Confirmation") of such Private Notes, if such procedure is available, into the
Exchange Agent's account at the Depository pursuant to the procedure for
book-entry transfer described below, must be received by the Exchange Agent
prior to the Expiration Date or (iii) the holder must comply with the guaranteed
delivery procedures described below.
 
     The tender by a holder that is not withdrawn prior to the Expiration Date
will constitute an agreement among such holder and the Company in accordance
with the terms and subject to the conditions set forth herein and in the Letter
of Transmittal.
 
     THE METHOD OF DELIVERY OF PRIVATE NOTES AND THE LETTER OF TRANSMITTAL AND
ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK
OF THE HOLDER. INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS USE
AN OVERNIGHT OR HAND DELIVERY SERVICE, PROPERLY INSURED. IN ALL CASES,
SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE AGENT
BEFORE THE EXPIRATION DATE. DO NOT SEND THE LETTER OF TRANSMITTAL OR ANY PRIVATE
NOTES TO THE COMPANY. HOLDERS MAY REQUEST THEIR RESPECTIVE BROKERS, DEALERS,
COMMERCIAL BANKS, TRUST COMPANIES OR NOMINEES TO EFFECT THE ABOVE TRANSACTIONS
FOR SUCH HOLDERS.
 
     Any beneficial owner(s) of the Private Notes whose Private Notes are
registered in the name of a broker, dealer, commercial bank, trust company or
other nominee and who wish(es)(s) to tender should contact the registered holder
promptly and instruct such registered holder to tender on such beneficial
owner's behalf. If such beneficial owner wishes to tender on such owner's own
behalf, such owner must, prior to completing and executing the Letter of
Transmittal and delivering such owner's Private Notes, either make appropriate
arrangements to register ownership of the Private Notes in such owner's name or
obtain a properly completed bond power from the registered holder. The transfer
of registered ownership may take considerable time.
 
     Signatures on a Letter of Transmittal or a notice of withdrawal described
below (see "-- Withdrawal of Tenders"), as the case may be, must be guaranteed
by an Eligible Institution (as defined below) unless the Private Notes tendered
pursuant thereto are tendered (i) by a registered holder who has not completed
the box titled "Special Delivery Instructions" on the Letter of Transmittal or
(ii) for the account of an Eligible Institution. In the event that signatures on
a Letter of Transmittal or a notice of withdrawal, as the case may be, are
required to be guaranteed, such guarantee must be made by a member firm of a
registered national securities exchange or of the National Association of
Securities Dealers, Inc., a commercial bank or trust company having an office or
correspondent in the United States or an "eligible guarantor institution"
(within the meaning of Rule 17Ad-15 under the Exchange Act) that is a member of
one of the recognized signature guarantee programs identified in the Letter of
Transmittal (an "Eligible Institution").
 
     If the Letter of Transmittal is signed by a person other than the
registered holder of any Private Notes listed therein, such Private Notes must
be endorsed or accompanied by a properly completed bond power, signed by such
registered holder exactly as such registered holder's name appears on such
Private Notes.
 
     If the Letter of Transmittal or any Private Notes are signed by trustees,
executors, administrators, guardians, attorneys-in-fact, officers of
corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and, unless waived by the Company,
evidence satisfactory to the Company of their authority to so act must be
submitted with the Letter of Transmittal.
 
     The Exchange Agent and the Depository have confirmed that any financial
institution that is a participant in the Depository's system may utilize the
Depository's Automated Tender Offer Program to tender Private Notes.
 
     All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of tendered Private Notes will be determined
by the Company in its sole discretion, which determination will be final and
binding. The Company reserves the absolute right to reject any and all Private
Notes not properly tendered or any Private Notes the Company's acceptance of
which would, in the opinion of counsel for the Company, be unlawful. The Company
also reserves the right to waive any defects, irregularities or conditions of
tender as to particular Private Notes. The Company's interpretation of the terms
and conditions of the
 
                                       39
<PAGE>   42
 
Exchange Offer (including the instructions in the Letter of Transmittal) will be
final and binding on all parties. Unless waived, any defects or irregularities
in connection with tenders of Private Notes must be cured within such time as
the Company shall determine. Although the Company intends to notify holders of
defects or irregularities with respect to tenders of Private Notes, neither the
Company, the Exchange Agent nor any other person shall incur any liability for
failure to give such notification. Tenders of Private Notes will not be deemed
to have been made until such defects or irregularities have been cured or
waived.
 
     While the Company has no present plan to acquire any Private Notes that are
not tendered in the Exchange Offer or to file a registration statement to permit
resales of any Private Notes that are not tendered pursuant to the Exchange
Offer, the Company reserves the right in its sole discretion to purchase or make
offers for any Private Notes that remain outstanding subsequent to the
Expiration Date and, to the extent permitted by applicable law, purchase Private
Notes in the open market, in privately negotiated transactions or otherwise. The
terms of any such purchases or offers could differ from the terms of the
Exchange Offer.
 
     By tendering, each holder of Private Notes will represent to the Company
that, among other things, (i) the Exchange Notes to be acquired by such holder
of Private Notes in connection with the Exchange Offer are being acquired by
such holder in the ordinary course of business of such holder, (ii) such holder
has no arrangement or understanding with any person to participate in the
distribution of the Exchange Notes, (iii) such holder acknowledges and agrees
that any person who is participating in the Exchange Offer for the purposes of
distributing the Exchange Notes must comply with the registration and prospectus
delivery requirements of the Securities Act in connection with a secondary
resale transaction of the Exchange Notes acquired by such person and cannot rely
on the position of the staff of the Commission set forth in certain no-action
letters, (iv) such holder understands that a secondary resale transaction
described in clause (iii) above and any resales of Exchange Notes obtained by
such holder in exchange for Private Notes acquired by such holder directly from
the Company should be covered by an effective registration statement containing
the selling security holder information required by Item 507 or Item 508, as
applicable, of Regulation S-K of the Commission and (v) such holder is not an
"affiliate," as defined in Rule 405 under the Securities Act, of the Company. If
the holder is a broker-dealer that will receive Exchange Notes for such holder's
own account in exchange for Private Notes that were acquired as a result of
market-making activities or other trading activities, such holder will be
required to acknowledge in the Letter of Transmittal that such holder will
deliver a prospectus in connection with any resale of such Exchange Notes;
however, by so acknowledging and by delivering a prospectus, such holder will
not be deemed to admit that it is an "underwriter" within the meaning of the
Securities Act.
 
RETURN OF PRIVATE NOTES
 
     If any tendered Private Notes are not accepted for any reason set forth in
the terms and conditions of the Exchange Offer or if Private Notes are
withdrawn, such unaccepted, withdrawn or non-exchanged Private Notes will be
returned without expense to the tendering holder thereof (or, in the case of
Private Notes tendered by book-entry transfer into the Exchange Agent's account
at the Depository pursuant to the book-entry transfer procedures described
below, such Private Notes will be credited to an account maintained with the
Depository) as promptly as practicable.
 
BOOK-ENTRY TRANSFER
 
     The Exchange Agent will make a request to establish an account with respect
to the Private Notes with the Depository for purposes of the Exchange Offer
within two business days after the date of this Prospectus, and any financial
institution that is a participant in the Depository's systems may make
book-entry delivery of Private Notes by causing the Depository to transfer such
Private Notes into the Exchange Agent's account at the Depository in accordance
with the Depository's procedures for transfer. However, although delivery of
Private Notes may be effected through book-entry transfer at the Depository, the
Letter of Transmittal or facsimile thereof, with any required signature
guarantees and any other required documents, must, in any case, be transmitted
to and received by the Exchange Agent at the address set forth below under
"-- Exchange Agent" on or prior to the Expiration Date or pursuant to the
guaranteed delivery procedures described below.
 
                                       40

GUARANTEED DELIVERY PROCEDURES
 
     Holders who wish to tender their Private Notes and (i) whose Private Notes
are not immediately available or (ii) who cannot deliver their Private Notes,
the Letter of Transmittal or any other required documents to the Exchange Agent
prior to the Expiration Date, may effect a tender if:
 
     (a) The tender is made through an Eligible Institution;
 
     (b) Prior to the Expiration Date, the Exchange Agent receives from such
         Eligible Institution a properly completed and duly executed Notice of
         Guaranteed Delivery substantially in the form provided by the Company
         (by facsimile transmission, mail or hand delivery) setting forth the
         name and address of the holder and the certificate number(s) of such
         Private Notes, stating that the tender is being made thereby and
         guaranteeing that, within three business days after the Expiration
         Date, the Letter of Transmittal (or a facsimile thereof), together with
         the certificate(s) representing the Private Notes in proper form for
         transfer or a Book-Entry Confirmation, as the case may be, and any
         other documents required by the Letter of Transmittal, will be
         deposited by the Eligible Institution with the Exchange Agent; and
 
     (c) Such properly executed Letter of Transmittal (or facsimile thereof) as
         well as the certificate(s) representing all tendered Private Notes in
         proper form for transfer and all other documents required by the Letter
         of Transmittal are received by the Exchange Agent within three business
         days after the Expiration Date.
 
     Upon request to the Exchange Agent, a Notice of Guaranteed Delivery will be
sent to holders who wish to tender their Private Notes according to the
guaranteed delivery procedures set forth above.
 
WITHDRAWAL OF TENDERS
 
     Except as otherwise provided herein, tenders of Private Notes may be
withdrawn at any time prior to the Expiration Date. To withdraw a tender of
Private Notes in the Exchange Offer, a written or facsimile transmission notice
of withdrawal must be received by the Exchange Agent at its address set forth
herein prior to the Expiration Date. Any such notice of withdrawal must (i)
specify the name of the person having deposited the Private Notes to be
withdrawn, (ii) identify the Private Notes to be withdrawn (including the
certificate number or numbers) and (iii) be signed by the holder in the same
manner as the original signature on the Letter of Transmittal by which such
Private Notes were tendered (including any required signature guarantees). All
questions as to the validity, form and eligibility (including time of receipt)
of such notices will be determined by the Company, in its sole discretion, whose
determination shall be final and binding on all parties. Any Private Notes so
withdrawn will be deemed not to have been validly tendered for purposes of the
Exchange Offer, and no Exchange Notes will be issued with respect thereto unless
the Private Notes so withdrawn are validly retendered. Properly withdrawn
Private Notes may be retendered by following one of the procedures described
above under "The Exchange Offer -- Procedures for Tendering" at any time prior
to the Expiration Date.
 
TERMINATION OF CERTAIN RIGHTS
 
     All registration rights under the Registration Rights Agreement accorded to
holders of the Private Notes (and all rights to receive additional interest on
the Notes to the extent and in the circumstances specified therein) will
terminate upon consummation of the Exchange Offer except with respect to the
Company's duty to keep the Registration Statement effective until the closing of
the Exchange Offer and, for a period of 180 days after the closing of the
Exchange Offer, to provide copies of the latest version of the Prospectus to any
broker-dealer that requests copies of such Prospectus in the Letter of
Transmittal for use in connection with any resale by such broker-dealer of
Exchange Notes received for its own account pursuant to the Exchange Offer in
exchange for Private Notes acquired for its own account as a result of
market-making or other trading activities.

        The Bank of New York also serves as Trustee under the Indenture.
 
FEES AND EXPENSES
 
     The expenses of soliciting tenders will be borne by the Company. The
principal solicitation is being made by mail; however, additional solicitation
may be made by telegraph, facsimile transmission, telephone or in person by
officers and regular employees of the Company and their affiliates.
 
     The Company has not retained any dealer-manager in connection with the
Exchange Offer and will not make any payments to brokers, dealers or others
soliciting acceptances of the Exchange Offer. The Company, however, will pay the
Exchange Agent reasonable and customary fees for its services and will reimburse
it for its reasonable, out-of-pocket expenses in connection therewith.
 
   
     The cash expenses to be incurred in connection with the Exchange Offer will
be paid by the Company and are estimated in the aggregate to be approximately
$500,000. Such expenses include registration fees, fees and expenses of the
Exchange Agent and the Trustee, accounting and legal fees and printing costs,
among others.
    
 
     The Company will pay all transfer taxes, if any, applicable to the exchange
of Private Notes pursuant to the Exchange Offer. If, however, a transfer tax is
imposed for any reason other than the exchange of the Private Notes pursuant to
the Exchange Offer, then the amount of any such transfer taxes (whether imposed
on the registered holder or any other persons) will be payable by the tendering
holder. If satisfactory evidence of payment of such taxes or exemption therefrom
is not submitted with the Letter of Transmittal, the amount of such transfer
taxes will be billed directly to such tendering holder.
 
CONSEQUENCE OF FAILURE TO EXCHANGE
 
     Participation in the Exchange Offer is voluntary. Holders of the Private
Notes are urged to consult their financial and tax advisors in making their own
decisions on what action to take.
 
     Private Notes that are not exchanged for the Exchange Notes pursuant to the
Exchange Offer will remain "restricted securities" within the meaning of Rule
144(a)(3)(iv) of the Securities Act. Accordingly, such Private Notes may not be
offered, sold, pledged or otherwise transferred except (i) to a person whom the
seller reasonably believes is a "qualified institutional buyer" within the
meaning of Rule 144A under the Securities Act purchasing for its own account or
for the account of a qualified institutional buyer in a transaction meeting the
requirements of Rule 144A, (ii) in an offshore transaction complying with Rule
903 or Rule 904 of Regulation S under the Securities Act, (iii) pursuant to an
exemption from registration under the Securities Act provided by Rule 144
thereunder (if available), (iv) pursuant to an effective registration statement
under the Securities Act or (v) to institutional accredited investors in a
transaction exempt from the registration requirements of the Securities Act,
and, in each case, in accordance with all other applicable securities laws and
the transfer restrictions set forth in the Indenture.
 
ACCOUNTING TREATMENT
 
     For accounting purposes, the Company will recognize no gain or loss as a
result of the Exchange Offer. The expenses of the Exchange Offer will be
amortized over the remaining term of the Notes.

                SELECTED CONSOLIDATED HISTORICAL FINANCIAL DATA
 
   
    The following table sets forth certain selected financial and operating data
on a consolidated historical basis for the Company as of December 31, 1994, 1995
and 1996 and March 31, 1997, and for the years ended December 31, 1994, 1995 and
1996 and the three months ended March 31, 1996 and 1997. The selected
consolidated historical financial data of the Company as of and for the years
ended December 31, 1994, 1995 and 1996, with the exception of data presented
under Other Financial Data, were derived from the consolidated financial
statements and the notes thereto of the Company, which have been audited by
Deloitte & Touche LLP, independent auditors, whose report has been included
herein. The selected consolidated historical financial data of the Company for
the three months ended March 31, 1996 and as of and for the three months ended
March 31, 1997 are derived from the unaudited consolidated financial statements
of the Company. In the opinion of management, the unaudited consolidated
financial statements include all adjustments, consisting of normal recurring
accruals, that are necessary for a fair presentation of the financial position
and results of operations for these periods.
    
 
   
    On January 1, 1997 and March 3, 1997, respectively, McCaw International
(Services), Ltd. (formerly Special Purpose Company No. 1) and McCaw
International (CANMEX), Ltd. (formerly Nextel Investment Company), both wholly
owned subsidiaries of Nextel, were merged into the Company. As these mergers
represent transfers between companies under common control, they have been
accounted for similar to poolings of interests; accordingly, the historical
financial statements for the periods presented prior to the mergers are restated
as though the companies had been combined from inception.
    
 
    The selected consolidated historical financial data should be read in
conjunction with "Pro Forma Consolidated Financial Statements" and the notes
thereto, "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and the Company's consolidated financial statements,
including the notes thereto, appearing elsewhere in this Prospectus.

(1) EBITDA consists of loss before interest expense, income tax benefit and
    depreciation and amortization. EBITDA is provided because it is a measure
    commonly used in the telecommunications industry. It is presented to enhance
    an understanding of the Company's operating results and is not intended to
    represent cash flow or results of operations for the periods presented.
    EBITDA is not a measurement under U.S. GAAP and may not be similar to EBITDA
    measures of other companies. See the Company's consolidated financial
    statements and the notes thereto appearing elsewhere in this Prospectus.
 
   
(2) For the purpose of computing the ratio of earnings to fixed charges,
    earnings consist of loss before income taxes, plus fixed charges, less
    income (loss) from equity method investments. Fixed charges consist of
    interest on all indebtedness, amortization of debt expense, and that portion
    of rental expense which the Company believes to be representative of
    interest. The deficiency (excess) for purposes of calculating the ratio of
    earnings to fixed charges for the years ended December 31, 1996, 1995 and
    1994, and the three months ended March 31, 1997 and 1996 was $11,121,352,
    $15,918,233, $(2,685,849), $10,309,587 and $958,247, respectively.

                  PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS
 
   
     The following unaudited pro forma consolidated financial statements present
the historical consolidated balance sheets and statements of operations after
giving effect to the Transactions and the Initial Offering. The unaudited pro
forma consolidated balance sheet as of March 31, 1997 gives effect to the
Argentina Transaction and the capital contribution that increased the Company's
interest in Mobilcom from 38% to 46.3% as if they had occurred at March 31,
1997. The unaudited pro forma consolidated statements of operations for the year
ended December 31, 1996 and for the three months ended March 31, 1997 give
effect to the Transactions and the Initial Offering as if they had occurred on
January 1, 1996. The following pro forma consolidated financial statements have
been derived from, and should be read in conjunction with, the consolidated
historical financial statements of the Company, Mobilcom and WVB including the
notes thereto, and the other financial and operating information appearing
elsewhere in this Prospectus. The pro forma adjustments are described in the
notes to the pro forma consolidated financial statements and investors are
encouraged to read such information carefully. The pro forma consolidated
financial statements are not necessarily indicative of the operating results or
financial position that would have been achieved by the Company, nor are they
indicative of the Company's future operating results or financial position.
    
 
   
     The Transactions which the pro forma consolidated financial statements give
effect to include: (i) Nextel's acquisition on January 30, 1997 of an 81.0%
interest in WVB for $186.3 million in market value of Nextel Class A Common
Stock and the simultaneous contribution of such interest to the Company; (ii)
the Company's acquisition of an approximately 38% interest in Mobilcom for $76.9
million and the capital contribution that increased the Company's ownership
interest in Mobilcom from 38% to 46.3%, which are accounted for using the equity
method; (iii) the Company's acquisition of a 30.0% interest in Infocom which is
accounted for using the equity method; (iv) the Argentina Transaction; and (v)
the pre-merger transfer to Nextel of NIC's assets and liabilities not associated
with the Company's investments in Mobilcom and Clearnet.

                          SELECTED PROPORTIONATE DATA
    
 
   
     The following table is not required by generally accepted accounting
principles ("GAAP") and is not intended to replace the Consolidated Financial
Statements prepared in accordance with GAAP. It is presented to provide
supplemental data. Because significant assets of the Company are not
consolidated and because of the substantial effect the formation of certain
joint ventures will have on the year-to-year comparability of the Company's
consolidated financial results, the Company believes that proportionate
financial and operating data facilitates the understanding and assessment of its
Consolidated Financial Statements.
    
 
   
     Under GAAP, the Company consolidates the entities in which it has a
controlling interest and uses the equity method to account for entities over
which the Company has significant influence but does not have a controlling
interest. In contrast, proportionate accounting reflects the Company's relative
ownership interests in operating revenues and expenses for both its consolidated
and equity method entities. Investments that are accounted for under the cost
method or are classified as available-for-sale are not subject to proportionate
accounting. Accordingly, total proportionate results show the Company's share of
significant operations over which it has the ability to exert significant
influence.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion and analysis should be read in conjunction with
the Company's consolidated financial statements and the notes thereto and the
pro forma financial information appearing elsewhere in this Prospectus.
 
OVERVIEW
 
     GENERAL
 
     McCaw International is a leading wireless communications services company
based on the number of people and the number of SMR channels in its licensed
service areas. The Company provides wireless communications services in the four
largest cities in Latin America and two of the largest cities in Asia. The
Company's markets cover approximately 230 million POPs, approximately 120
million of which are in Latin America. McCaw International is the largest SMR
service provider in Brazil and Mexico, and holds the largest SMR channel
position in Argentina. McCaw International's strategy is focused on leveraging
its leading analog dispatch or SMR channel positions in its principal markets
and using Nextel's experience and supplier relationships to upgrade its services
from analog dispatch to ESMR services. 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.
 
   
     On January 1, 1997 and March 3, 1997, respectively, McCaw International
(Services), Ltd. (formerly Special Purpose Company No. 1 ("SPC#1")) and McCaw
International (CANMEX), Ltd. (formerly Nextel Investment Company ("NIC")), both
wholly owned subsidiaries of Nextel, were merged into the Company. As these
mergers represent transfers between companies under common control, they have
been accounted for in a manner similar to poolings of interests; accordingly,
the historical financial statements reflect the combined financial position and
results of operations of the Company, SPC#1 and NIC (collectively referred to as
the "Company") for all periods presented.
    
 
   
     As of December 31, 1996, the Company owned 100% of McCaw Argentina, 30.1%
of Mobilcom, 3.7% of Clearnet, 30% of Infocom and the right to receive 25.2% of
the profits of the Shanghai GSM System. Accordingly, at December 31, 1996, the
Company's consolidated financial statements consolidate the accounts of the
Company and McCaw Argentina. The Company's 30.1% interest in Mobilcom and 30%
interest in Infocom are accounted for using the equity method. The Company's
3.7% investment in Clearnet is considered an investment in marketable securities
and is reflected at fair market value, and the Company's right to receive 25.2%
of the profits of the Shanghai GSM System is accounted for using the cost
method. Upon consummation of the Argentina Transaction on May 6, 1997, the
Company's ownership interest in McCaw Argentina was reduced to 50%. Under U.S.
GAAP in effect on the date thereof, McCaw Argentina will be accounted for under
the equity method.
    
 
   
     On January 30, 1997, Nextel acquired 81% of WVB, a Brazilian SMR provider,
and concurrently contributed the interest to the Company. Accordingly, the
Company's pro forma financial statements consolidate and the Company's
historical financial statements for 1997 and thereafter will consolidate, McCaw
Brazil.
    
 
   
     As of April 30, 1997, the Company owned approximately 46.3% of the
outstanding equity of Mobilcom. On June 30, 1997, the Company increased its
ownership interest in Mobilcom to 48.1%. Beginning on October 24, 1997 and for a
two-year period thereafter, pursuant to the Mobilcom Put, holders of
approximately 37% of the outstanding capital stock of Mobilcom have the right to
put such stock to the Company at its fair market value upon the occurrence of
certain events. In addition, the Company has options to acquire up to an
additional 29.5% of Mobilcom, which expire on March 3, 1998 (collectively, the
"Mobilcom Options"). To the extent the Mobilcom Put or the Mobilcom Options are
exercised and the Company thereafter owns more than 50% of the equity of
Mobilcom, Mobilcom would be consolidated for accounting purposes. There

can be no assurance that either of the foregoing transactions will occur. See
"Risk Factors -- Contingent Capital Requirements."
 
     REVENUES
 
     The Company derives its revenues primarily from (i) activation fees, which
are the initial charges paid by a new subscriber for service, (ii) monthly fixed
access charges, which vary depending on the plan chosen by the subscriber, (iii)
airtime charges, which are billed based on usage, (iv) monthly rental charges,
which are derived from the leasing of wireless equipment, (v) the sale of
handsets to subscribers and (vi) in certain markets, various local taxes and
fees which are passed on to customers. The Company sets the pricing of the
different components of its services in accordance with its marketing plan in
each of the countries in which it operates, taking into account, among other
things, competitive factors. Usage revenues are accrued for during the month
incurred and billed at the end of the monthly billing cycle. Rental fee revenues
and monthly fixed access charges are billed in advance and recognized in the
period service was delivered. Equipment sales are recognized at the time of
sale.
 
     In general, revenue per subscriber is higher in the Company's markets than
in the United States. In 1995 the average monthly SMR revenue per subscriber in
the United States was approximately $16 compared to $45 in the Company's Latin
American markets. In 1995 the average monthly cellular revenue per subscriber in
the United States was approximately $51 compared to $90 in the Company's markets
($90 represents the combined average monthly cellular bill for Argentina,
Brazil, China, Mexico and the Philippines). In part, this is due to the poor
quality of landline service and unsatisfied demand for telephony services
generally found in emerging markets. In many emerging markets, including most of
those in which the Company has operations, wireless service is often used as a
substitute for landline service, which increases the relative usage per
subscriber and the revenue per subscriber. As the Company upgrades its existing
networks to ESMR networks and begins to offer enhanced services and features, it
expects increased revenue per subscriber. Over time, the Company expects such
increases will be partially offset by a decline in rates resulting from
increased competition and lower average usage per subscriber.
 
     By principally targeting business customers, the Company believes it
experiences lower customer turnover, acquisition costs per subscriber and bad
debt expense and a generally more stable customer base than if it targeted
customers in the general population. In addition, customers using the Company's
iDEN-based ESMR systems will be required to have ESMR handsets which will not be
compatible with a cellular system. The Company believes that the cost of
switching to a competing cellular service may also result in lower turnover.
 
   
     In some of the Operating Companies, however, the Company has experienced
relatively high rates of churn and bad debt expenses. However, the Company has
taken a number of steps to reduce these levels including tightening the credit
screening process, instituting the requirement of longer term contracts and
formulating more aggressive collection processes.
    
 
   
     The Company expects the revenues of the Operating Companies to increase
significantly over the next few years due to the following factors: (i) the
launch of commercial SMR service in Argentina in February 1997, (ii) the
continued expansion of the nationwide paging service acquired as part of the
Argentina Transaction and (iii) the planned launch of commercial ESMR services
in the Philippines by the end of 1997, in Brazil in the first quarter of 1998,
and in Argentina and Mexico later in 1998. In addition, as the Company upgrades
its existing networks to ESMR networks, it anticipates its revenues will
increase substantially due to the large increase in subscriber capacity that
results from ESMR and the expected increase in average revenue per subscriber
that results from the Company's ability to offer enhanced services and features.
    
 
   
     The Company is subject to the laws and regulations governing
telecommunication services in effect in each of the countries in which it
operates. These laws and regulations cover, among other things, the number of
licenses that can be used in any one service area by affiliated companies, the
construction and loading requirements necessary to retain a license, the number
of telephone numbers that can be assigned to an individual licensee and the
rights of a licensee to interconnect with a public telecommunications network.
    
 
                                       49
<PAGE>   52
 
   
Each of these factors can have a significant influence on the Company's ability
to generate revenues and are subject to change by the governmental agency
responsible for determining the laws and regulations in the respective
countries. The Company cannot predict what future laws and regulations might be
passed that could have a material effect on the Company's results of operations.
The Company assesses the impact of significant changes in laws and regulations
on a regular basis.
    
 
     COSTS AND EXPENSES RELATED TO REVENUES
 
     Costs and expenses related to revenues include both the cost of service and
the cost of sales. Cost of service represents the cost of maintaining networks,
interconnection charges, site lease costs, technical expenses and utilities. The
Company anticipates the cost of service will increase with the expansion of its
wireless networks. However, as a percentage of revenue, the Company anticipates
that cost of service will decrease over time as a result of economies of scale
in operations and efficiencies achieved through digital technology. Cost of
sales represents the cost of equipment sold or leased. As the Company expands,
its business will experience an overall increase in cost of sales offset in part
by a decrease in the cost of handsets and other wireless communications
equipment. Cost of sales as a percentage of revenue are expected to decrease
over time as a result of the expected decrease in the cost of handsets and other
wireless communications equipment.
 
     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
 
     At the corporate level, selling, general and administrative expenses
consist primarily of compensation expenses and to a lesser extent include
expenses such as rent, professional fees and other general corporate expenses.
At the Operating Company level, selling, general and administrative expenses
consist primarily of customer acquisition costs, advertising and to a lesser
degree, salaries and office expenses. On a historical basis, substantially all
of selling, general and administrative expenses have been incurred at the
corporate level. As the consolidated Operating Companies expand their wireless
communications networks and add subscribers, the Company expects a larger
portion of selling, general and administrative expenses to be incurred at the
Operating Company level. The Company expects selling, general and administrative
expenses to increase over time as it continues to expand its operations. As a
percentage of revenues, however, the Company expects these expenses will
decrease as a result of anticipated revenue growth as the number of subscribers
increases.
 
     The Company is billed directly on a monthly basis by landline telephone
companies for interconnect services and by various governments for taxes. The
Company bills its subscribers for these charges and is responsible for
collecting the charges from them. Many of the countries in which the Company
operates do not have established credit bureaus, thereby making it more
difficult for the Company to ascertain the creditworthiness of potential
customers. Accordingly, the Company experiences a relatively high level of bad
debt expense in most of its markets. In particular, the Company's bad debt
expense as a percentage of revenue and customer turnover in Brazil and Mexico
have been significantly higher than that in the Company's other markets.
 
     DEPRECIATION AND AMORTIZATION
 
   
     Historically, the Company's depreciation and amortization expense has been
primarily attributable to the depreciation of property, plant and equipment at
its corporate headquarters. As a result of the acquisition of WVB, the Company
expects depreciation and amortization to increase significantly. In particular,
licenses and goodwill totaling $263.7 million has been recognized in this
transaction and will be amortized over 20 years using the straight-line method.
    
 
   
     INTEREST INCOME (EXPENSE), NET
    
 
   
     Interest income represents income earned on notes receivable and cash and
cash equivalents. Interest income is expected to increase in future periods as
the approximately $482 million of Initial Offering proceeds are invested.
Historically, interest expense has consisted of amounts payable on notes payable
to Nextel. Interest expense is expected to increase significantly in future
periods as a result of the Initial Offering.

<PAGE>   53
 
   
     LOSS FROM EQUITY METHOD INVESTMENTS
    
 
   
     Loss from equity method investments represents the Company's proportionate
share of net income or loss from its investments in companies of which it owns
between 20% and 50%. As of December 31, 1996, loss from equity method
investments consisted of the Company's proportionate share of net income or loss
from its 30.1% interest in Mobilcom and 30% interest in Infocom. After the
Argentina Transaction, income from equity method investments will include the
Company's 50% interest in McCaw Argentina. Loss from equity method investments
also includes amortization of the excess purchase price over net assets acquired
in its investments in entities accounted for under the equity method.
    
 
   
     OTHER, NET
    
 
   
     Other, net is comprised of both other income and other expenses. Other
income consists of fees received by the Company for management services provided
to Shanghai McCaw and Infocom and salary and expense reimbursement for the
Company's employees who are working at Infocom. In 1995, other expenses included
a $15.0 million charge to operations representing an other than temporary
decline in its Mobilcom investment as a result of the decline in the Mexican
Peso.
    
 
   
     MINORITY INTEREST
    
 
   
     Minority interest represents the 19% interest in McCaw Brazil not owned by
the Company.
    
 
   
     INCOME TAX BENEFIT (PROVISION)
    
 
   
     The Company is subject to income taxes in the United States and in each of
the jurisdictions in which it operates. In the United States, the Company is
included in the consolidated tax return of Nextel; however, the tax accounts are
stated as if the Company filed a separate return.
    
 
   
     In the periods prior to the Company's merger with NIC, the Company was
precluded from recognizing income tax benefits associated with its U.S. net
operating losses because it was not reasonably certain that the Company would
generate taxable income. Historically on a stand-alone basis, NIC generated
taxable income from the interest earned on its investments of cash and cash
equivalents. As accounting rules related to the pooling-of-interest method of
accounting preclude the offsetting of the Company's historical net operating
losses against NIC's historical taxable income, the Company has recognized only
the NIC income tax expense in the combined financial statements presented prior
to the merger date. Subsequent to the merger occurring in the first quarter of
1997, the Company is allowed to combine the tax attributes of the merged
companies. As the combined enterprise expects to continue recognizing U.S. net
operating losses in the foreseeable future, no U.S. income tax benefits are
expected to be realized until the Company generates taxable income.
    
 
   
     Subsequent to the acquisition of WVB, the Company recognized income tax
benefit related to its operations in Brazil. Certain of the Brazilian
subsidiaries have taxable temporary differences allowing for the recognition of
the tax benefits derived from net operating losses. The Company expects that the
tax benefits from net operating losses in these Brazilian subsidiaries will
continue to be recognized in its financial statements throughout 1997.
    
 
   
HISTORICAL RESULTS OF OPERATIONS
    
 
   
THREE MONTHS ENDED MARCH 31, 1997 AND 1996
    
 
   
     The Company acquired WVB on January 30, 1997 and commenced commercial SMR
operations in Argentina in February 1997. Accordingly, there were no revenues or
costs and expenses related to revenues in the three months ended March 31, 1996.
For the first quarter of 1997, substantially all of the revenues and costs and
expenses related to revenues result from the two months of Brazilian SMR
operations included in the Company's consolidated financial statements.
    
 
   
     Selling, general and administrative expenses increased $3.0 million to $3.9
million for the three months ended March 31, 1997 from $0.8 million for the
three months ended March 31, 1996. Approximately
    
 
                                       51
<PAGE>   54
 
   
$2.0 million of the increase is attributable to the WVB operations which have
been included in the Company's consolidated results of operations commencing
January 30, 1997. The remaining increase can be attributed to a $0.5 million
increase in Argentina start-up costs and a $0.4 million increase in staffing and
expenses associated with the corporate oversight function.
    
 
   
     Depreciation and amortization increased to $2.6 million for the three
months ended March 31, 1997 from $0.0 million for the three months ended March
31, 1996. Approximately $2.4 million of the increase is attributable to the
amortization of licenses and goodwill recognized in the acquisition of WVB. The
remaining increase is due to $0.2 million of amortization of licenses in
Argentina which commenced commercial operations in February, 1997.
    
 
   
     Interest income increased $1.7 million to $2.8 million for the three months
ended March 31, 1997 from $1.1 million for the three months ended March 31,
1996. The increase was primarily attributable to income recognized on the
investment of the proceeds from the Initial Offering.
    
 
   
     Interest expense of $5.6 million was recognized during the three months
ended March 31, 1997 of which $4.9 million represented accretion on the Initial
Offering and amortization of associated debt issue costs. Additionally, NIC
recognized $0.4 million of interest on a note payable to Nextel, and WVB
incurred approximately $0.3 million of interest on short term borrowings. No
interest expense was recognized during the three months ended March 31, 1996.
    
 
   
     Loss from equity method investments increased $0.6 million to $1.9 million
for the three months ended March 31, 1997 from $1.3 million for the three months
ended March 31, 1996. The increase was primarily attributable to an increase in
amortization expense of $0.5 million of the excess purchase price over net
assets acquired in its Infocom and additional Mobilcom investments. The amount
of loss recognized in connection with the Company's investment in Mobilcom
increased $0.3 million to $0.8 million during the three months ended March 31,
1997 due to the increase in the Company's ownership percentage. Additionally,
during the three months ended March 31, 1997, the Company recognized $0.2
million in income from its 30% equity interest in Infocom that was acquired in
June, 1996.
    
 
   
     Minority interest in the net loss of WVB totaled $0.4 million during the
three months ended March 31, 1997. The amount is attributable to the minority
shareholder's interest in WVB subsequent to the acquisition of an 81% interest
in WVB by the Company on January 30, 1997.
    
 
   
     The Company recognized an income tax benefit of $0.5 million during the
three months ended March 31, 1997 compared to an income tax provision of $0.4
million during the three months ended March 31, 1996. The income tax benefit
recognized during the three months ended March 31, 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 March 31, 1996 was primarily attributable
to the taxes associated with NIC's interest income.
    
 
   
YEAR ENDED DECEMBER 31, 1996 AND 1995
    
 
   
     WVB was acquired in January, 1997 and commercial operations in Argentina
began in February, 1997. Accordingly, there were no revenues or costs and
expenses related to revenues for the years ended December 31, 1996 and 1995.
    
 
   
     Selling, general and administrative expenses increased $9.0 million to $9.3
million for the year ended December 31, 1996 from $0.3 million for the year
ended December 31, 1995. The increase is attributable to $6.3 million of
additional expenses related to the increase in staffing and expenses associated
with the corporate oversight function, $1.3 million related to McCaw Argentina
start-up costs, and $1.4 million of inventory write-offs at McCaw Argentina.
    
 
   
     Depreciation and amortization expense increased to $0.2 million for the
year ended December 31, 1996 from $0.0 million for the year ended December 31,
1995. The increase is primarily attributable to depreciation from property,
plant and equipment associated with the corporate oversight function.
    
 
                                       52
<PAGE>   55
 
   
     Interest income decreased $1.9 million to $4.3 million for the year ended
December 31, 1996 from $6.2 million for the year ended December 31, 1995. The
decrease is primarily due to lower amounts of cash and cash equivalents on hand
during 1996.
    
 
   
     Interest expense of $0.3 million represents interest accrued on an
intercompany note payable to Nextel outstanding during the fourth quarter of
1996. No interest-bearing intercompany notes existed during 1995.
    
 
   
     Loss from equity method investments decreased $0.9 million to $6.0 million
for the year ended December 31, 1996 from $6.9 million for the year ended
December 31, 1995. The decrease is primarily attributable to the net loss of
Mobilcom decreasing from $31.3 million for the year ended December 31, 1995 to
$11.8 million for the year ended December 31, 1996. The decrease in the net loss
of Mobilcom was partially offset by the Company's increase in ownership
percentage during 1996 and $1.3 million at additional amortization of the excess
purchase price over net assets acquired in its Infocom and additional Mobilcom
investments. The decrease in the net loss of Mobilcom was primarily due to
foreign currency exchange losses incurred in 1995 and interest expense
reductions during 1996.
    
 
   
     Other, net consisted of income of $0.4 million for the year ended December
31, 1996 compared to expense of $15.0 million for the year ended December 31,
1995. Income recognized during 1996 primarily relates to amounts recognized
under technical services agreements with Infocom and Shanghai McCaw. Other
expenses recognized during 1995 consists primarily of a $15.0 million write down
of the Company's investment in Mobilcom, which represented an other than
temporary decline in value resulting from the decline in the Mexican Peso.
    
 
   
     Income tax expense decreased $0.7 million to $1.4 million for the year
ended December 31, 1996 from $2.1 million for the year ended December 31, 1995.
The decrease in income tax expense is attributable to NIC's interest income
decreasing during 1996 as a result of lower amounts of cash and cash equivalents
on hand throughout the year.
    
 
   
YEAR ENDED DECEMBER 31, 1995 AND 1994
    
 
   
     Selling, general and administrative expenses of $0.3 million for the year
ended December 31, 1995 represents the initial formation the Company's corporate
oversight function during the fourth quarter of 1995. No selling, general and
administrative expenses occurred in 1994 as the Company was an investment
holding entity prior to the establishment of the corporate oversight function.
    
 
   
     Depreciation and amortization was insignificant during the years ended
December 31, 1995 and 1994.
    
 
   
     Interest income increased $3.5 million to $6.2 million for the year ended
December 31, 1995 from $2.7 million for the year ended December 31, 1994. The
increase is primarily due to higher amounts of cash and cash equivalents on hand
during 1995.
    
 
   
     Loss from equity method investments of $6.9 million for the year ended
December 31, 1995 is comprised of $2.4 million of amortization of the excess
purchase price over net assets acquired in its Mobilcom investment and $4.5
million of the Company's proportionate share of the net loss of Mobilcom, which
was acquired during 1995. No equity method investments existed during 1994.
    
 
   
     Other expense recognized during 1995 consists primarily of a $15.0 million
write down of the Company's investment in Mobilcom which represented an other
than temporary decline in value resulting from the decline in the Mexican Peso.
    
 
   
     Income tax expense increased $1.2 million to $2.1 million for the year
ended December 31, 1995 from $0.9 million for the year ended December 31, 1994.
The increase in income tax expense is attributable to NIC's interest income
increasing during 1995 as a result of lower amounts of cash and cash equivalents
on hand throughout the year.

LIQUIDITY AND CAPITAL RESOURCES
 
   
     The Company has incurred historical net losses of approximately $38.6
million since inception through March 31, 1997. These losses result from
expenditures required for the development of the Company's wireless
communications networks, other start-up costs and the fact that as of December
31, 1996 no consolidated revenues had been recorded. On a pro forma basis giving
effect to the Transactions and the Initial Offering, for the year ended December
31, 1996 and the three months ended March 31, 1997, the Company's EBITDA would
have been negative $25.5 million and negative $5.7 million, respectively. 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. Through December 31, 1996, funds necessary to finance
the Company's activities have been provided to the Company primarily by its
parent, Nextel, in the form of equity contributions. Nextel is not obligated to
provide any additional funding to the Company.
    
 
   
     Net cash used by operating activities for 1996 equaled $3.0 million. Net
cash used by investing activities equaled $72.3 million for 1996. Net cash
provided by financing activities equaled $43.0 million for 1996.
    
 
   
     The Company currently estimates its proportionate share of funding
requirements at the Operating Companies for 1997 and 1998 to be approximately
$319 million and $187 million, respectively. These amounts consist primarily of
the purchase of switches and other equipment, the acquisition of cell sites, the
cost of constructing the network and operating losses. The Company currently
estimates that approximately $319 million of such requirements will be related
to expenditures in Brazil, $74 million in Argentina, $68 million in Mexico and
$18 million in the Philippines. The Company expects approximately $195 million
of the capital expenditures for equipment will be funded at the Operating
Company level through the Motorola Financing, however, the amount of borrowings
under the Motorola Financing that Nextel has agreed to make available to the
Company is limited to $95 million. Based on discussions with Nextel and
Motorola, the Company believes that it will be able to obtain sufficient funding
under the Motorola Financing to meet its business plan. The Company expects to
fund the balance of its requirements with the net proceeds from the Initial
Offering.
    
 
     The Company's capital requirements may also be affected by arrangements the
Company has with other investors in the Operating Companies. In order to retain
the contractual right to designate a majority of the board of directors of
Mobilcom and a member of the Technology Committee of such board of directors,
the Company must have invested approximately $76.8 million in Mobilcom through
certain qualified capital transactions by March 1998. As of April 30, 1997, the
Company had invested approximately $64.9 million in such qualified capital
transactions. In addition, beginning on October 24, 1997, pursuant to the
Mobilcom Put, holders of approximately 37% of the outstanding capital stock of
Mobilcom have the right for two years to put the entire amount of their holdings
to the Company at its appraised fair market value for cash in the event of a
Mobilcom Put Event. The Mobilcom Put is automatically exercisable on October 24,
1999 whether or not a Mobilcom Put Event occurs. Valuation of Mobilcom for
purposes of the Mobilcom Put will be based on an appraisal by an investment
bank, with the minimum appraisal for 100% of Mobilcom equal to $150 million. To
the extent such appraisal exceeds $250 million, 50% of such excess will be
included in the valuation. In connection with a capital call on June 7, 1996
Mobilcom shareholders purchased additional shares of Mobilcom based on a $200
million valuation of Mobilcom (which values the Mobilcom Put at approximately
$66 million). If the Company does not pay the Minimum Amount and to the extent
the Company does not otherwise acquire a majority of the outstanding capital
stock of Mobilcom, the Company will lose its right to designate a majority of
the board of directors of Mobilcom and a member of the Technology Committee and
its ability to block certain significant actions of Mobilcom. The Company has
the option to purchase, before March 3, 1998, up to an additional 29.5% of
Mobilcom's common stock. To the extent the Company owns a majority of the voting
stock in Mobilcom after giving effect to the exercise of the Mobilcom Put, the
Company will not be affected by the failure to have invested the Minimum Amount
by March 1998 since its equity ownership will entitle it to elect a majority of
the board of directors of Mobilcom. As of April 30, 1997, the Company owned
approximately 46.3% of the voting stock of Mobilcom.
 
     On February 26, 1997, Mobilcom shareholders approved the $27 million
Mobilcom Capital Call. Nextel funded the Company's pro rata share of the
Mobilcom Capital Call (approximately $10 million) with a cash
 
                                       54

contribution. Additionally, because not all of the Mobilcom shareholders funded
their pro rata share of the Mobilcom Capital Call, the Company had the
opportunity to purchase additional shares of Mobilcom by funding the
unsubscribed portion of the Mobilcom Capital Call (approximately $10 million).
The Company thereby increased its equity interest in Mobilcom from approximately
38% to approximately 46.3%. The Company funded its purchase of the unsubscribed
shares from the proceeds of the Initial Offering. The funds from the Mobilcom
Capital Call were used by Mobilcom to satisfy certain overdue obligations
(approximately $11 million), to purchase the remaining 51% of Natel that
Mobilcom does not own and to fund operations. The Natel acquisition was
consummated on April 16, 1997.
 
     The other shareholder in McCaw Brazil has the right between October 31,
2001 and November 1, 2003, to require McCaw Brazil to redeem such shareholder's
interest in McCaw Brazil at fair market value as determined pursuant to an
appraisal procedure.
 
     The Company anticipates funding the Partner Contingencies with the net
proceeds of the Initial Offering, issuances of additional debt and equity
securities at the Company and Operating Company levels, future equity
investments in the Operating Companies by new local partners and capital
contributions from Nextel in the form of cash or Nextel common stock. Nextel has
no obligation to provide any such financing and there can be no assurance that
the Company will be able to fund Partner Contingencies. The failure to fund a
Partner Contingency may have a material adverse effect on the Company. See "Risk
Factors -- Contingent Capital Requirements."
 
     The Company believes that the net proceeds from the Initial Offering,
together with borrowings expected to be available under vendor financing,
including the Motorola Financing, and the estimated proceeds from the Brazil
Equity Sale will be sufficient to fund the Company's current operations,
including the planned expansion of its existing operations for approximately 36
to 48 months from the Closing Date; however, there can be no assurance in this
regard. Thereafter, the Company will need substantial additional capital. If the
Company's plans or assumptions change, if its assumptions prove to be
inaccurate, if it consummates investments or acquisitions in addition to those
currently contemplated, if it experiences unanticipated costs or competitive
pressures, if the Brazil Equity Sale is not consummated or if the net proceeds
from the Initial Offering, together with the proceeds of any such borrowings,
otherwise prove to be insufficient, the Company may be required to seek
additional capital sooner than currently anticipated. The terms of any
borrowings under the Motorola Financing are subject to negotiation and execution
of definitive agreements. The Company may seek to raise such additional capital
from public or private equity or debt sources. There can be no assurance that
the Company will be able to raise such capital on satisfactory terms, if at all.
See "Risk Factors -- Significant Capital Requirements."
 
     In the future, the Company may consider obtaining financing from various
sources, including 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. 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.
 
     In November 1996, Nextel, McCaw International and Motorola entered into the
Motorola MOU. Under the Motorola MOU, Motorola agreed to provide an aggregate of
$400 million in vendor financing to Nextel and McCaw International for the
worldwide purchase of iDEN equipment and services and ancillary products (such
as switches). In March 1997, Motorola and Nextel entered into a term sheet
increasing the maximum worldwide vendor financing available to Nextel and McCaw
International to $650 million, with a maximum non-U.S. amount outstanding of
$400 million, subject to certain per country limits as agreed in the Motorola
MOU. The Motorola MOU sets a limit of $125 million per country (other than the
United States and Canada) on the amount that may be borrowed under the Motorola
Financing. Nextel, McCaw International and Motorola agreed to an initial
commitment to McCaw Brazil, McCaw Argentina and Infocom under the Motorola
Financing of $125 million, $81 million and $15 million, respectively.
Commitments provided by Motorola to provide financing to any Operating Company
count 100% against Motorola's $650 million aggregate commitment. Currently
Motorola has not committed any financing for Mexico. The Motorola
 
                                       55
<PAGE>   58
 
MOU contemplates that the loans under the Motorola Financing will bear interest
at a rate of 2% to 4% over prime rate, depending on the Operating Company
placing the order and the country in which such company is installing the iDEN
equipment and is likely to have a maturity of up to six years. Borrowings by an
Operating Company will be secured by all the assets and stock of such Operating
Company and it is expected that the Company will guarantee such borrowings on a
pro rata basis based on the equity interest of such Operating Company owned by
the Company (with the exception of Brazil where the Company will be required to
guarantee 100% of such borrowings).
 
     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 March 31, 1997, Nextel had borrowed $110
million pursuant to the Motorola Financing. Accordingly, there can be no
assurance that more than $95 million under the Motorola Financing will be
available to fund the Operating Companies' equipment purchases. 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, McCaw 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. Nextel has agreed with the Company not
to cause a Forced Repayment.
 
   
     In May 1997, Infocom and Motorola entered into a term sheet (the
"Philippines Motorola Financing"), pursuant to which Motorola will provide up to
$15 million of vendor financing to Infocom. The Philippines Motorola Financing
provides for a maturity of two years and an annual interest rate of prime plus
250 basis points or, at Infocom's option, LIBOR plus 463 basis points. Pursuant
to the Philippines Motorola Financing the 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.
    
 
     McCaw International intends to structure its future capital contributions
to the Operating Companies as equity contributions and/or loans and thereafter
to rely on the payment of dividends and/or interest and principal payments as a
means of obtaining cash from the Operating Companies. The Company will evaluate
on an on-going basis which means of contributing cash to the Operating Companies
is most effective.
 
     The Company holds a majority interest in McCaw Brazil and a 50% interest in
McCaw Argentina. The Company's other assets consist of minority ownership
interests in the Operating Companies and approximately $482 million of the net
cash proceeds from the Initial Offering which have been invested in short-term
investments. Even though the Company participates in the management of the
Operating Companies, except in China and Canada, it cannot control the outcome
of matters submitted to the shareholders of the Operating Companies in which it
has less than a majority interest. In addition, the Company may be unable to
access the cash flow of its affiliated companies because (i) it does not have
the requisite control to cause such entities to pay dividends, and (ii)
substantially all of such entities are parties to or expected to become parties
to vendor financing or other borrowing agreements that severely restrict or
prohibit the payment of dividends, and such entities are likely to continue to
be subject to such restrictions and prohibitions for the foreseeable future. The
Motorola Financing will prohibit the payment of dividends to the Company by the
Operating Companies that have debt outstanding under the Motorola Financing. To
the extent any Motorola Financing is outstanding in 2002, when cash interest
payments on the Notes are required to be made, the Company would need to obtain
funds for such interest payments from other sources. The Company does not have a
revolving credit or other facility providing for funding of the Company. In
addition, to the extent the Company contributes capital to the Operating
Companies in the form of loans, interest payments to the Company may be subject
to withholding taxes. See "Risk Factors -- Substantial Indebtedness; Ability to
Service Debt; Refinancing Risks."

INFLATION AND FOREIGN CURRENCY EXCHANGE
 
     The net monetary assets of the Company's subsidiaries are subject to
foreign currency exchange risks since they are maintained in local currency.
Certain of the Company's subsidiaries operate in countries in which the rate of
inflation is significantly higher than that of the United States. The Company
will attempt to protect its earnings from inflation and possible currency
devaluation by trying to periodically adjust its prices in local currencies and
in some cases setting its prices in direct relation to the U.S. dollar. However,
there can be no assurance that any significant devaluation against the U.S.
dollar could be offset, in whole or in part, by a corresponding price increase.
 
     The countries in which the Company's subsidiaries now conduct business
generally do not restrict the repatriation or conversion of local or foreign
currency. There can be no assurance, however, that this will be the case in each
market that the Company may enter in the future or that this situation will
continue in the Company's existing markets. See "Risk Factors -- Currency Risks
and Exchange Controls." The Company's subsidiaries are all directly affected by
their respective countries' governmental, economic, fiscal and monetary policies
and other political factors.
 
NET OPERATING LOSS CARRYFORWARDS
 
   
     As of December 31, 1996, the Company had approximately $6.0 million of net
operating loss carryforwards ("NOLs") available in the United States, which
expire commencing in 2010. See "Certain Relationships and Related
Transactions -- Tax Sharing Agreement." The Company may be limited in its
ability to use NOLs in any one year depending on its ability to generate
sufficient taxable income. A number of other factors may also have an effect on
the Company's ability to fully utilize these NOLs, such as U.S. tax law
provisions limiting the use of the NOLs if certain changes in the Company's
ownership occur. In addition, as of December 31, 1996 there were the following
NOLs at the Operating Company level: (i) $15.7 million in Brazil; (ii) $1.9
million in Argentina and (iii) $57.5 million in Mexico. Such NOLs are only
available to be utilized as a potential future reduction of taxes at the
Operating Company level.

                               INDUSTRY OVERVIEW
 
DEMAND FOR COMMUNICATIONS SERVICES IN EMERGING MARKETS
 
     The rapid expansion and modernization of economies in many emerging markets
have resulted in a significant increase in demand for telecommunications
services. Telecommunications services are viewed as essential to sustaining
rapid economic growth and to improving productivity and competitiveness in
emerging markets. Telephone service and system quality in most of these markets,
however, remains poor due to under investment in landline infrastructure. In
addition, telecommunications providers have been unable to meet the rising
demand for telecommunications service which has resulted in long waiting lists
for the installation of telephone lines and service. Countries in which the
Company operates currently have an average of 6.9 access lines per 100 people
compared to 59.4 access lines per 100 people in the United States. Waiting time
for the installation of a landline telephone is estimated to range from nine
months in Mexico to approximately 3.5 years in Brazil and as long as nearly nine
years in the Philippines.
 
     While wireless communications in the United States provides an attractive
supplemental service to a well developed and reliable landline telephone system,
in many emerging markets wireless communications have become an important
alternative to the relatively antiquated, overburdened and unreliable landline
telephone systems. Furthermore, in most of the emerging markets where the
Company operates, wireless communications services tend to be more readily
available and in many cases provide higher quality service than landline
systems. In addition, wireless networks can be constructed relatively quickly
and are less expensive to install than landline networks. In 1995, the average
cellular penetration rate in the emerging markets in which the Company operates
was .7% (compared to a cellular penetration rate of 12.8% in the United States).
By 2000, the average cellular penetration rate in those countries is expected to
increase to 3.9% representing an average annual growth rate of 39.1%, compared
to 17% in the United States. In terms of regional cellular growth from 1996
through the year 2001, the number of cellular subscribers is estimated to grow
an average of 37% per year in Latin America and 34% per year in the Asia Pacific
region.
 
     The following table sets forth certain information with respect to the
emerging markets in which the Company operates, together with comparative
information for the United States.

WIRELESS TECHNOLOGY
 
     Currently, three systems dominate the market for wireless communications
services: SMR/ESMR, cellular/PCS and paging. The Operating Companies utilize one
or more of each of these forms of wireless communications. The following is a
brief description of each type of wireless communications system.
 
     SMR/ESMR
 
     SMR, also referred to as "trunked radio" or wireless dispatch
communications, is primarily a business communications tool which provides cost
effective point-to-multipoint or "one-to-many" voice communications. This
service allows reliable, flexible and convenient communications among a defined
group of users typically within a business or "work group."
 
     Historically, SMR operators have generally been unable to provide mobile
telephone service competitive with that provided by cellular operators because
of various factors affecting SMR system capacity and voice quality. The primary
factors affecting capacity and voice quality have included: the smaller portion
of the radio spectrum allocated to SMR; regulations and procedures that
initially served to spread ownership of SMR licenses among a large number of
operators in each market, thereby limiting the amount of SMR spectrum available
to any particular operator; and the limitations of traditional SMR technology
which employs analog transmission and a single site, high power transmitter
configuration which precludes the use of any given SMR frequency by more than
one caller at a time within a given service area.
 
     Partially as a result of the constraints on capacity, SMR operators,
including the Operating Companies that offer SMR services, have traditionally
emphasized radio dispatch service, which involves shorter duration
communications than mobile telephone service and places less demand on system
capacity. The traditional SMR market, therefore, has been oriented primarily to
business customers such as contractors, service companies, security firms and
delivery services that have significant field operations and need to provide
their personnel with the ability to communicate directly with one another,
either on a one-to-one or on a one-to-many basis. The broader market of
businesses and individuals that are primarily interested in mobile telephone
service has been largely beyond the reach of traditional SMR operators.
 
     The 800 MHz SMR spectrum in the United States and in other countries is
generally adjacent and functionally equivalent to cellular frequencies. As a
result, ESMR technology has been developed specifically to provide digital
service using the SMR frequency band.
 
     Similar to cellular telephone technology, ESMR technology is based upon the
division of a given geographical area into a number of cells and the
simultaneous re-use of radio channels in non-contiguous cells within the system.
Each cell contains a low power transmitter-receiver at a base station that
communicates by central switching point or mobile switching center that controls
the routing of calls and that, in turn, is connected to the public switched
telephone network. The switch enables ESMR mobile telephone users to move freely
from cell to cell while continuing their calls. In general, an ESMR network
requires fewer sites than are needed for a PCS network.
 
     ESMR technology provides the capability to offer integrated wireless
communications services over one network utilizing common cell and digital
switching infrastructures as well as multi-functional handsets. Historically,
the mobile telephone, paging, dispatch and mobile data market segments were
served by discrete networks utilizing separate technologies, handsets and phone
numbers despite the fact that a number of users subscribed to one or more of
these services. In contrast to this historical segmentation of the wireless
industry, the Company believes that ESMR technology will make it possible to
integrate all such segments of wireless mobile communications.
 
     Motorola has developed a proprietary digital technology for use in SMR
networks, known as iDEN, that allows analog SMR networks to be upgraded to
digital ESMR networks offering enhanced services such as instant conferencing
(enhanced dispatch), mobile telephone (interconnect), short-text messaging with
acknowledgment (alphanumeric paging) and data transmission. The iDEN technology
uses a version of the Time Division Multiple Access ("TDMA") digital
transmission technology used by certain providers of digital cellular services.
The iDEN technology carries up to three voice and/or control paths per channel
for
 
                                       59
<PAGE>   62
 
the ESMR network's mobile telephone function and up to six voice and/or control
paths per channel for the instant conferencing function.
 
     During the third and fourth quarters of 1996, Nextel launched commercial
service of its iDEN-based ESMR networks in several markets in the United States,
including Chicago, Detroit, Boston, Denver, Atlanta, New York,
Washington/Baltimore, Los Angeles, Northern California and the Pacific
Northwest, under the "PowerFone" brand name. Additionally, during the fourth
quarter of 1996, Clearnet launched commercial services of its iDEN-based ESMR
network in the Ontario-Quebec market under the "MiKE" brand name. Both Nextel
and Clearnet have announced their plans to launch their iDEN-based ESMR networks
in additional markets during 1997 and 1998. As of December 31, 1996, Nextel
provided services to approximately 300,000 ESMR subscriber units and Clearnet
provided services to approximately 5,000 ESMR subscriber units. See "Risk
Factors -- Technology Risks."
 
     The implementation of an ESMR network utilizing iDEN involves upgrading
existing 800 MHz SMR systems via two fundamental changes in system architecture.
First, the analog transmission format of traditional SMR systems is replaced by
a digital TDMA transmission format. Second, the single high-powered transmitter
typical of traditional SMR systems is replaced or augmented by a number of low
powered transmitters, dispersed across the coverage area, enabling frequency
reuse. Additionally, the ESMR frequency reuse system uses a mobile switching
office to enable the hand-off of transmissions from one transmitter to another
as subscribers move across the coverage area.
 
     Cellular/PCS
 
     Cellular telephone systems are capable of providing high quality, high
capacity voice and data communications to and from vehicle-mounted and hand-held
radio telephones. Cellular telephone systems are capable of handling thousands
of calls at any one time and providing service to hundreds of thousands of
subscribers in any particular area.
 
     Cellular telephone technology is based upon the division of a given
geographical area into a number of cells and the simultaneous re-use of radio
channels in non-contiguous cells within the system. Each cell contains a low
power transmitter-receiver at a base station that communicates by a switch that
controls the routing of calls and that, in turn, is connected to the public
switched telephone network. The switch enables cellular telephone users to move
freely from cell to cell while continuing their calls.
 
     Cellular telephone systems generally offer subscribers the features offered
by the most up-to-date landline telephone services. Cellular telephone systems
are interconnected with the landline telephone network which allows subscribers
to receive and originate local, long-distance and international calls from their
cellular telephones. As a result, cellular telephone system operators require an
interconnection arrangement with the local landline telephone companies and the
terms of such arrangements are material to the economic viability of the system.
 
     A cellular telephone system's capacity can be increased in various ways.
Initially, increasing demand may be satisfied by adding available channel
capacity to cells. When all available channels are used, further growth can be
accomplished through a process known as cell splitting. Cell splitting entails
dividing a single cell into a number of smaller cells allowing for greater
channel re-use, thereby increasing the number of calls that can be handled in a
given area.
 
     Currently, the three most widely deployed analog air-interface cellular
standards include Advanced Mobile Phone System ("AMPS"), Nordic Mobile Telephone
("NMT"), and Total Access Communications System ("TACS"). The AMPS and TACS
systems currently operate in the 800 and 900 MHz frequency band and the NMT
systems can operate in either the 450 or 900 MHz ranges. The most prevailing
air-interface standards utilizing digital technology include GSM and Digital
Advanced Mobile Phone System ("DAMPS"). DAMPS systems are currently deployed in
the 800 MHz frequency range and soon will be constructed on the 1.8-1.9 GHz
frequency ranges. DAMPS utilizes either TDMA or Code Division Multiple Access
transmission techniques. Both AMPS and DAMPS are the most widely deployed
systems in the
 
                                       60
<PAGE>   63
 
Americas. GSM, which is widely deployed in Europe and Asia, can operate at
either the 900 MHz or 1.8-2.0 GHz frequency ranges.
 
     Paging
 
     Paging is a well-established wireless technology, and is widely available
in many countries. A paging system typically consists of a number of transmitter
sites connected to a central messaging center. The messaging center receives
incoming messages from the public telephone network and prepares batches of
messages for transmission to subscribers. There are two basic types of paging
services: numeric (digital display) and alphanumeric, which allows subscribers
to receive and store messages of up to 5,000 characters consisting of both
letters and numbers. Historically, paging was a one-way communication service;
however, technological advances in wireless messaging have made two-way
communications possible. Two-way paging systems allow message acknowledgment
responses and the transmission of short data messages by the paging subscriber.
In emerging markets where telephone penetration is low, paging often provides an
affordable alternative to public telephone service.
 
     The table below illustrates some of the main differences between SMR/ESMR,
cellular/PCS and paging.

     McCaw International is a leading international wireless communications
services company based on the number of people and the number of SMR channels in
its licensed service areas. The Company provides wireless communications
services in the four largest cities in Latin America and two of the largest
cities in Asia. The Company's markets cover approximately 230 million POPs,
approximately 120 million of which are in Latin America. McCaw International,
through the Operating Companies, is the largest SMR service provider in Brazil
and Mexico, and holds the largest SMR channel position in Argentina. McCaw
International's strategy is focused on leveraging its leading analog dispatch or
SMR channel positions in its principal markets and using Nextel's experience and
supplier relationships to upgrade its services from analog dispatch to digital
ESMR services. 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.
 
     McCaw International believes that wireless communications opportunities in
emerging markets, particularly in Latin America and Asia, are very attractive
compared to the market in the United States due to the poor telecommunications
infrastructure, low teledensity, favorable competitive environments and greater
expected economic growth rates in those markets. The Company believes that the
low cost of its wireless spectrum relative to cellular and PCS, as well as the
large and growing demand for wireless communications services in its markets,
provides it with a significant opportunity to expand its subscriber base in an
efficient and cost-effective manner.
 
     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 has a contractual right through its
Chinese joint venture to receive 25.2% of the profits generated by the Shanghai
GSM System and has a 3.7% interest in Clearnet, a Canadian wireless
communications services company. The Operating Companies have networks in some
of the largest cities in their respective countries, including Sao Paulo, Mexico
City, Buenos Aires and Rio de Janeiro, which are the four largest cities in
Latin America, and Shanghai and Manila, which are two of the largest cities in
Asia. The subscriber base of the Operating Companies has grown 59% from
approximately 111,000 subscribers at December 31, 1995 to approximately 177,000
subscribers at December 31, 1996.

     The Company believes it has established the leading position in terms of
the number of SMR channels in its principal markets. The Company's asset base
includes (i) 5,190 SMR channels in the 800 MHz band (which is adjacent to and
functionally equivalent to cellular frequencies) and the related licenses to
provide wireless communications services over such channels and (ii) deployed
networks in the markets where it operates. At January 31, 1997, the Company's
licenses and assets were acquired for approximately $365 million, or
approximately $3.72 per POP, which is significantly less than the prices paid
for cellular and PCS licenses in comparable markets around the world.

     McCaw International currently markets its wireless communications services
primarily to business customers with mobile work forces, such as service
companies, security firms, contractors and delivery services. In general, the
Company markets its services through a direct sales force, dealers and
independent agents. Companies with mobile work forces represent growing sectors
of the economy in the Company's markets. These types of businesses often have
the need to provide their personnel with the ability to communicate directly
with one another, either on a one-to-one or a one-to-many basis. By upgrading
its operations to provide ESMR services, the Company will increase capacity
significantly and be in a position to target a broader customer base. The
Company currently plans to launch ESMR commercial service in the Philippines by
the end of 1997, in Brazil during the first quarter of 1998 and in Argentina and
Mexico later in 1998. McCaw International differentiates itself from its
competitors by (i) providing superior quality telecommunications services, (ii)
focusing on customer service and (iii) targeting primarily business customers.

STRATEGY
 
     The Company's strategy is to grow by upgrading and expanding its existing
networks to incorporate digital wireless communications services, which will
enable the Company to increase its subscriber base and revenues, and to pursue
new investment opportunities in markets which satisfy the characteristics
described above. The key elements of the Company's strategy are:
 
     Capitalize on Leading Position. In most of its markets, the Company has a
larger SMR channel position than any other SMR service provider, which allows it
to compete effectively with other wireless communications service providers. Its
large channel positions also reduce the capital expenditures required to upgrade
to digital networks and create operating synergies.
 
     Expand by Providing Digital Enhanced Services. The Company intends to
upgrade its analog SMR networks to digital ESMR networks using Motorola's iDEN
technology. The upgrade to digital networks will allow the Company to increase
capacity significantly and also offer additional services and features, which
the Company believes will lead to increases in its subscriber base and average
monthly revenue per subscriber.
 
     Develop Cost-Efficient Networks. The Company's strategy of investing in SMR
channels has enabled it to acquire spectrum in its markets at a much lower cost
than cellular and PCS providers have paid in comparable markets around the
world. As a result, the Company believes it has an important competitive
advantage relative to cellular and PCS providers.
 
     Leverage Nextel and Motorola Relationships. Nextel is the largest SMR and
ESMR provider in the United States. The Company intends to access Nextel's
technology, operations, supplier relationships, network development and
marketing expertise in upgrading its SMR networks to ESMR in its existing
markets and to leverage its relationship with Nextel in entering new markets. In
addition, the Company believes that it will benefit from Nextel's relationship
with Motorola, which is expected to supply the Company with iDEN equipment and
services. The Company will have access to financing for iDEN equipment on
substantially similar terms as Nextel under a vendor financing commitment among
Nextel, the Company and Motorola. By utilizing Nextel's expertise and
relationships with suppliers, in particular with Motorola, the Company believes
that it will be able to deploy networks that are competitive with cellular and
PCS networks.
 
     Partner with Strong Local Groups. McCaw International seeks financially
strong local groups to invest as equity holders at the operating level. The
Company's local partners often own or have access to an existing strategic asset
base (such as real estate for cell sites or distribution outlets) that the
Operating Companies can use to reduce capital expenditures, operating costs and
network deployment time. Local partners also frequently play an active role in
securing licenses, obtaining necessary regulatory approvals and managing
governmental relations for the Operating Companies.
 
     Maintain Active Management Role. The Company seeks to acquire controlling
ownership and management positions in its principal markets to the extent local
law does not restrict foreign ownership or management. Where the Company holds
less than a majority interest in an Operating Company, it manages its investment
through contractual arrangements that, other than in China and Canada, ensure
board representation and enable it to veto certain corporate actions. The
Company actively participates in the management of the Operating Companies,
other than in China and in Canada, by (i) selecting the key members of the local
management team, (ii) developing the system's technology and infrastructure,
(iii) developing business plans and marketing plans together with local
management, and (iv) maintaining close working relationships with local
partners.
 
     Pursue New Investments in Attractive Markets. The Company is continuing to
pursue new investment opportunities in geographic areas that offer attractive
market fundamentals. At present, the Company plans to focus on emerging markets
in Asia and Latin America. The Company believes that such markets offer
favorable long-term economic growth prospects and that geographic concentration
may provide significant business synergies.

SPECTRUM POSITION
 
     The Operating Companies' current license holdings represent one of the
largest international wireless footprints, covering a total of 230 million POPs.
Based on its proportionate equity ownership, the Company's investments cover
approximately 98 million proportionate POPs.
 
   
     The Company's spectrum strategy in the short-term is to strengthen its
channel position in its existing markets. For example, the Argentina Transaction
doubled the Company's spectrum position in Argentina. The Company will also seek
to acquire SMR channels or other wireless communications spectrum in other
selected urban centers in emerging markets on an opportunistic basis. See
"Summary -- Recent Developments."
    
 
   
     In order to construct a digital network utilizing iDEN technology, the
Company believes that at least 100 SMR channels are necessary in any given
market. Generally, the Company estimates that each SMR channel has the capacity
to provide service to approximately 100 subscribers using analog SMR technology.
Deploying digital technology on these SMR channels will increase subscriber
capacity significantly. Moreover, the Company believes its large channel
position reduces capital expenditures required to upgrade to digital networks.
McCaw International owns or has options to acquire at least 100 channels in each
of the markets in which it intends to construct digital networks. In smaller
markets, McCaw International will continue to focus its efforts on growing its
SMR subscriber base. The Company's licenses and assets were acquired for
approximately $365 million as of January 31, 1997, or approximately $3.72 per
POP, which is significantly less than the prices paid for cellular or PCS
licenses in comparable markets around the world.

NETWORK IMPLEMENTATION, DESIGN AND CONSTRUCTION
 
     The Company's networks are in various stages of development. In 1996, the
Company began to build-out its ESMR network in the Philippines and its SMR
network in Argentina, and continued to build-out its SMR network in Brazil. In
1997, the Company intends to begin the design and development of its ESMR
network in Argentina, Brazil and Mexico and to continue to build-out its ESMR
network in the Philippines. The Company plans to launch commercial ESMR services
in the Philippines by the end of 1997, in Brazil during the first quarter of
1998 and in Argentina and Mexico later in 1998.
 
     As the Company builds out its ESMR networks primarily using iDEN, it
intends to leverage Nextel's expertise and relationships in converting its
United States SMR networks to ESMR networks. Nextel is the largest operator of
SMR and ESMR services in the United States.
 
     The Company's critical design criteria for its upgrade to ESMR include:
 
     - Contiguous wide area coverage of substantially all of the major
       population areas and traffic corridors in its licensed areas;
 
     - Signal quality comparable to that currently provided by existing cellular
       carriers;
 
     - Call "hand-off" for mobile telephone service throughout the ESMR
       networks;
 
     - Minimization of blocked and dropped calls;
 
     - The ability to offer advanced features such as data transmission and
       message services; and
 
     - Cost-efficient routing of calls to minimize local interconnection costs
       and toll charges and to provide maximum utilization of the Company's ESMR
       network facilities.
 
     The Company believes careful frequency planning is necessary prior to
commencing network construction in order to ensure seamless coverage over the
entire network. Frequency planning involves the selection of specific areas in
the Company's markets for the placement of transmitter sites and the
identification of specific frequencies that will be employed at each site in the
initial configuration. Sites will be selected on the basis of their coverage and
on frequency propagation characteristics.
 
     In addition to frequency planning and system design, the implementation of
the proposed digital wireless networks requires site acquisition, equipment
procurement, construction and equipment installation, testing and optimization.
Sites are selected on the basis of their proximity to targeted customers, the
ability to acquire and build the site and frequency propagation characteristics.
Site procurement efforts include obtaining leases and permits and, in many
cases, zoning approvals. Once the requisite governmental approvals are obtained,
the preparation of each site, including grounding, ventilation, air conditioning
and construction, typically takes three months, while equipment installation,
testing and optimization generally takes an additional four weeks. Following
commencement of system operations in a selected market, the Company expects to
add new sites to its networks continually in order to improve coverage and
capacity.
 
                                       67
<PAGE>   70
 
     One of the Company's objectives is to reduce the risk of delays during the
initial build-out of its ESMR networks while maintaining the integrity of the
system design. During the initial implementation, the Company intends, where
feasible, to use its existing sites, sites already occupied by other
communications service providers and other sites where zoning approvals and
other necessary permits are likely to be obtained easily. The Company also plans
to pursue concurrently access to multiple sites to mitigate delays resulting
from any permit denials and to use prefabricated buildings and pre-installed
equipment where possible in order to accelerate the installation process.
 
     In certain instances, the Company's ability to proceed with the build-out
of its ESMR networks in its coverage areas or elsewhere may be subject to
successful negotiation of site acquisitions or leases, the availability of
equipment and receiving necessary governmental approvals. In addition, the
timing of the scheduled build-out will be subject to obtaining additional
financing on a timely basis, and typical construction and other delays. See
"Risk Factors -- Significant Capital Requirements for Operations" and "--
Expansion; Management of Growth."
 
BUSINESS DEVELOPMENT
 
     The Company's business development objective is to pursue undervalued
license opportunities in major population centers in emerging markets throughout
the world. Consistent with this objective, the Company intends to expand its
subscriber base by building high-quality digital wireless networks in select
countries. The Company will pursue such opportunities by acquiring or investing
in projects in emerging markets that meet the Company's investment criteria. The
Company's criteria for investment include: (i) large, unsatisfied demand for
telecommunications; (ii) favorable economic growth, business and regulatory
climate; (iii) the availability of strong local equity partners; (iv) the
ability to have an active management role; (v) emerging market economies and
high-density population areas; and (vi) favorable SMR/ESMR investment
opportunities.
 
     Although the Company plans to direct its business development efforts
primarily toward SMR/ESMR opportunities, it intends to make technology and
spectrum decisions based on (i) the relative cost and availability of spectrum
in each market, (ii) the nature of its existing operations in nearby
geographical areas, (iii) appropriateness of a given technology in a specific
market, and (iv) return on investment.
 
OPERATIONS AND INVESTMENTS
 
     The Operating Companies offer wireless communications services in Latin
America (Brazil, Argentina and Mexico), Asia (Philippines and Shanghai, China)
and Canada.
 
BRAZIL
 
   
     The Company has an 81% equity interest in McCaw Brazil, the largest SMR
service provider in Brazil with over a 50% market share by subscribers and owns
or has options to purchase licenses for 1,700 SMR channels in Brazil, the
largest SMR channel position of any SMR provider in the country. McCaw Brazil
provides service under the tradename "AirLink."
    
 
     Country Overview. With a population of approximately 160 million, Brazil is
the largest country in Latin America and the fifth largest in the world. Over
77% of Brazil's inhabitants reside in urban areas. The two largest cities in
Brazil are Sao Paulo, with a population of approximately 18.4 million and Rio de
Janeiro, with a population of approximately 12 million. Brazil has the highest
GDP in Latin America, accounting for approximately 40% of Latin America's
aggregate GDP. Sao Paulo and Rio de Janeiro, urban areas in which McCaw Brazil
has the largest SMR channel positions, account for over 50% of the economic
activity in Brazil.
 
     Beginning in December 1993, the Brazilian government launched an economic
stabilization plan called the Real Plan (the "Real Plan"), which was intended to
reduce inflation by decreasing certain public expenditures, collecting
liabilities owed to the Brazilian government, increasing tax revenues,
continuing a privatization program and introducing a new currency, the Real.
Following the implementation of the Real Plan, inflation dropped significantly
from previous levels, which at times had exceeded 40% per month, to
 
                                       68
<PAGE>   71
 
monthly rates of between 1% and 3%, and the value of the Brazilian Real has been
relatively stable since its introduction.
 
     Although Brazil is the fifth most populated country in the world, it ranks
only thirty-ninth in terms of telephone density. Less than 2% of the rural
population and only 19% percent of all residences have telephone service,
compared to 94% in the United States. In addition, 45% of Brazilian businesses
do not own a telephone. The waiting list for landline telephone service in
Brazil can be as long as approximately 3.5 years.
 
     Although Brazil was the last major country in Latin America to grant
cellular licenses, it is now Latin America's largest cellular market, with more
than 1.5 million subscribers as of December 31, 1995, which represented 33% of
the total Latin American cellular subscriber base. Despite the large number of
cellular subscribers in Brazil, the country's cellular penetration rate is only
 .8%, which is well below the United States 1995 cellular penetration rate of
12.8%. Driven by the backlogged demand for telecommunications, Brazil's cellular
market has experienced substantial growth over the past few years, making it one
of the fastest growing wireless markets in Latin America. The number of cellular
subscribers in Brazil increased from 22,500 in 1992 to 1.5 million in 1995, a
compound annual growth rate of over 300%. Over 40% of all subscribers were in
Sao Paulo. Brazil's subscriber growth is expected to continue, with the number
of subscribers projected to increase to over nine million in 2000, an average
annual growth rate of 46%. By the year 2000, Brazil's penetration rate is
expected to be 5.5% and the country's share of Latin America subscribers is
expected to reach 42%. At an average revenue per subscriber of $119 per month,
Brazil's revenue per cellular subscriber is more than two times the average in
the United States.
 
     The SMR business in Brazil is underdeveloped compared to the U.S. market.
In 1995, Brazil had approximately 34,000 SMR subscribers or a .02% SMR
penetration rate compared to 7.0% in the U.S. The average revenue per SMR
subscriber per month of $67 is four times the comparable U.S. average.
 
   
     Operating Company Overview. McCaw Brazil provides SMR services in 10 of
Brazil's largest cities including Sao Paulo, Rio de Janeiro, Belo Horizonte and
Brasilia.
    
 
     McCaw Brazil has over 460 SMR channels installed and operational in Brazil.
It has 30 radio sites, five of which are in Sao Paulo and six in Rio de Janeiro.
McCaw Brazil has a centralized customer service and installation center located
in Sao Paulo.
 
   
     The Company acquired McCaw Brazil's operations in January 1997 and has
performed a review of McCaw Brazil's business operations, billing and reporting
practices. Based on its review to date, the Company has determined that McCaw
Brazil's past reporting practices may have resulted in an overstatement in the
number of revenue-generating subscriber units for the relevant periods.
Specifically, the number of subscriber units reported may have included (i)
units used by customers who were intermittent or seasonal users of McCaw
Brazil's SMR services, but were not active during the periods reported, (ii)
units issued to persons who had canceled or otherwise terminated their active
use of McCaw Brazil's SMR services, but had not returned their subscriber units,
and (iii) units issued as demonstration units, but not activated as revenue-
generating units.
    
 
   
     The Company has determined that the previously reported number of SMR units
for McCaw Brazil as of December 31, 1996, which was reported to be more than
16,000, including more than 12,000 in Sao Paulo, may be overstated by
approximately 15%. The overstatement in the number of SMR subscriber units for
McCaw Brazil does not have any impact on the accuracy of the revenue, expense or
other financial data reported by the Company with respect to McCaw Brazil's
operations (other than in the context of any information expressed as a "per
subscriber unit" amount).
    
 
   
     McCaw Brazil intends to upgrade to ESMR in Sao Paulo, Rio de Janeiro and
Belo Horizonte, the three largest metropolitan cities in Brazil. This will
increase system capacity and allow McCaw Brazil to offer a broader range of
services to a broader set of business customers. Preliminary system design for
the greater Sao Paulo area and Rio de Janeiro are currently underway and the
Company has entered into iDEN equipment purchase contracts with Motorola with
respect to iDEN equipment for each city. McCaw Brazil plans to launch ESMR
commercial service in Sao Paulo in the first quarter of 1998. The Company
intends to evaluate the timing of any steps in connection with an upgrade to
ESMR in Belo Horizonte and any other cities in
    
 
                                       69

Brazil based on the then-current competitive and regulatory environment. See
"Risk Factors -- Wireless Communications Operations -- Government Regulation"
and "-- Possible Delay in Offering ESMR Services in Brazil."
    
 
   
     McCaw Brazil offers its customers a broad range of services and pricing
plans designed to meet the specific needs of its customers. It offers dispatch
and integrated service plans (dispatch and interconnect). As of March 6, 1997,
approximately 22% of McCaw Brazil's subscribers were primarily interconnect
users, 34% were dispatch users and 44% were users of both dispatch and
interconnect. These plans include the sale or rental of various models of
handsets. The basic price package consists of a monthly fee of approximately
$40, interconnect rates per minute ranging from $.24 to $.31 and dispatch rates
per minute ranging from $.15 to $.23.
    
 
     McCaw Brazil's sales and marketing efforts currently focus primarily on
providing cost-effective local and regional integrated services (dispatch and
interconnect). Its target markets are businesses engaged in transportation,
construction, security, services and also include utilities and government
agencies. McCaw Brazil utilizes both a direct sales force as well as dealers and
independent agents. It currently has over 13 direct sales representatives and 57
dealers and independent agents.
 
     McCaw Brazil is headquartered in Sao Paulo and has branch offices in seven
other major cities. As of December 31, 1996, McCaw Brazil had 137 employees. Of
these, 115 were based in Sao Paulo.

     acquired 94 percent, and in July 1994, the remaining 6 percent, of the
     capital stock of Via Radio-1 Telecomunicacoes, S.A., ("VR-1"). In November
     1994, the ownership of VR-1 was transferred from McCaw Brazil to VRA.
    
 
   
          - ATG-Telecomunicacoes a Comercio Ltda. and Radio Telecomunicacoes do
     Brasil Ltda. In November 1993, VRA acquired all of the outstanding capital
     stock of ATG Telecomunicacoes e Comercio, Ltda. ("ATG"), and its 70 percent
     owned subsidiary, Radio Telecomunicacoes do Brazil, Ltda.
     ("Radio-Telecom"). In July 1994, VRA acquired the remaining 30 percent of
     capital stock of Radio-Telecom.
    
 
   
          - Air-fone Participacoes e Empreendimentos S/C Ltda. In July 1994,
     McCaw Brazil indirectly acquired all the outstanding capital stock of
     Air-fone Participacoes e Empreendimentos S/C Ltda.

     ("Airfone") which, in turn, held all of the outstanding capital stock of
     Airfone Comercio e Servicos de Radiofonia, Ltda. and SOW Comercio e
     Servicos de Radiofonia, Ltda.
    
 
   
          - Master-Tec Industria e Comercio de Produtos. In September 1994,
     McCaw Brazil indirectly acquired 49 percent of the capital stock of
     Master-Tec with an option to acquire the remaining 51 percent interest.
    
 
   
     Competition. McCaw Brazil is the largest SMR service provider in Brazil. In
addition, it has the largest SMR channel position of any service provider in
Brazil. There are a number of SMR competitors in Brazil, including MComCast (a
joint venture between Comcast Corporation and Banco Garantia), MCS and Radio
Movil Digital Americas, Inc.
    
 
   
     On February 20, 1997, the Ministry of Communications released the new SMR
Rules (the "New SMR Rules") (i) permitting the combination of adjacent channels
in certain frequencies in the 400 MHz, 800 MHz and 900 MHz band and (ii)
requiring the use of digital technology for SMR systems operating in channels
401 to 600 of the 806-821 MHz and 851-866 MHz bands. The New SMR Rules also
provide that channels which have already been assigned to licensees, including
the Company, will be the object of a study addressing the prospective regrouping
of such channels for application in systems using digital technology. Because
the New SMR Rules allow SMR operators to combine adjacent channels to create
contiguous blocks and may provide for a regrouping of SMR channels to create
more contiguous blocks in the future, SMR operators may have additional
technology choices available to them. Although the Company does not believe that
the New SMR Rules will materially affect its technology decisions or the
attractiveness of McCaw Brazil's product or service offerings, the New SMR Rules
and technology decisions by other SMR operators, including existing and future
competitors, may increase competition in Brazil. The proposed regulations issued
on May 15, 1997 and June 25, 1997, if enacted by the Ministry of Communications
as drafted, would impose limitations on the Company's ability to (i) obtain
direct telephone numbers for all of its subscriber units in Brazil and (ii)
interconnect with the public telecommunications network, and therefore, may
limit the Company's ability to compete effectively with other wireless
communications service providers in Brazil, including the operators of the Band
B cellular licenses.
    
 
     Brazil is one of the last major emerging countries to have only one
cellular provider per market. Telebras, the government-owned holding company
that controls the local telephone operators, is currently the only provider of
cellular service in Brazil. The current waiting list for a cellular telephone is
estimated to be three million people, with more than one million in Sao Paulo
where the average waiting time for a cellular telephone is two years. Due to the
demand for cellular telephony, the average price of a new cellular telephone on
the secondary market is estimated to be $3,000. In addition, there is reported
to be a 3.5 year waiting list for a landline phone. The average price on the
secondary market for a landline in Sao Paulo is estimated to be between $3,000
and $6,000.
 
   
     In June 1997 and July 1997, the Government of Brazil awarded Band B
cellular licenses covering two of the ten areas throughout Brazil, including Sao
Paulo, pursuant to the Band B Rules. The Band B Rules divide the country into
ten regions for the auction of Band B cellular licenses. The total of the
minimum bids required by the Brazilian government for each of Brazil's ten
regions is $3.7 billion. This equates to a value of approximately $23 per POP in
Brazil. The minimum bid for the city of Sao Paulo is $600 million or
approximately $33 per POP in Sao Paulo. However, under the Band B Rules, a
cellular license winner can provide service in only one major Brazilian market
and one secondary market (e.g., the winner of the Sao Paulo license will be
precluded from owning the Rio de Janeiro license). In addition, future licensing
and commencement of cellular services will not be permitted until December 31,
1999. Some of the largest telecommunications companies in the world are expected
to be granted cellular licenses in the Band B auction, which will result in
significant competition in the Company's Brazilian markets. See "Risk
Factors -- Possible Delay in Offering ESMR Services in Brazil."
    
 
     Partner Description. On January 30, 1997, Nextel acquired an 81% equity
interest in McCaw Brazil for a purchase price of $186.3 million, which was paid
with shares of Nextel Class A Common Stock, and simultaneously contributed its
interest in McCaw Brazil to the Company. The Telcom Group owns the remaining 19%
equity interest in McCaw Brazil.

     The Company is currently in discussions with several large Brazilian
corporate groups regarding the possible sale of up to a 15% equity interest in
the Brazil Holding Company. The proceeds from any such sale will be applied to
the upgrade of McCaw Brazil's network to ESMR. There can be no assurance that
the Company will be able to consummate any such transaction.
    
 
   
     Regulatory and Legal Overview.  The Ministry of Communications is the
Brazilian telecommunications authority responsible for administering and
regulating the SMR industry. In particular, the Ministry of Communications
regulates SMR licensing procedures and enforces both industry-wide and
contract-specific operating requirements. Notwithstanding the above, the
President of Brazil has announced that, as a result of the upcoming
privatization of the entire public telecommunications system, the Government of
Brazil may eliminate the Ministry of Communications and transfer its functions
to a new regulatory agency.
    
 
   
     Before McCaw Brazil can launch commercial iDEN-based ESMR services in
Brazil, it will need to obtain the following approvals from the Ministry of
Communications: (i) project installation approval; and (ii) post-installation
operating approval. In addition, before McCaw Brazil can commence ESMR service,
"type certifications" must be obtained from the Ministry of Communications with
respect to the equipment to be deployed in Brazil. Motorola has received type
certification for most of its iDEN equipment, however, the Nortel switch and the
subscriber units that are used with iDEN networks have not yet been type
certified. The Company believes that these approvals will be obtained on a
timely basis. No assurance can be given that the Ministry of Communications will
grant the approvals or that the Company's planned roll-out of ESMR will not be
delayed.
    
 
   
     Since July 13, 1994, it had been the Ministry of Communication's practice
to grant SMR licenses for a 15-year period and to renew such licenses for an
equal period upon submission of an application to the Ministry of
Communications. Certain of the Company's licenses granted prior to July 13, 1994
were granted for a term of five years and the Company believes that such
licenses have been automatically extended for a term of 15 years from their
original issuance date in accordance with Administrative Ruling No. 478.
Effective July 20, 1996, however, Law No. 9295 (the "Minimum Law"), modified
existing law so that SMR licenses granted after such effective date are issued
for a period of ten years and renewable for an additional ten-year period upon
submission of an application to the Ministry of Communications. The reduction to
ten years of the term and renewal periods for the licenses was confirmed by
Decree No. 2197, effective April 19, 1997. In either case, a license will be
renewed absent existing violations of applicable rules and regulations and upon
application 18 months prior to the expiration of the license. The Company
believes the legal doctrine of vested right ("direito adquirido") under
Brazilian law should insulate the existing terms of SMR licenses issued prior to
July 20, 1996, from the changes effected by the Minimum Law. All of the
Company's licenses were granted prior to July 20, 1996. Notwithstanding the
Minimum Law, a bill was signed into law on July 16, 1997 (the "General Law"),
which, among other things, revokes several provisions of the Minimum Law,
including the ten-year license term. Pursuant to the General Law, absent any new
regulations, existing SMR licenses will remain valid for the term for which they
were issued, however, to be renewed or extended, the term of the licenses must
be adapted to comply with the General Law. The General Law does not specify the
term of renewal or extension of SMR licenses. There can be no assurance that the
Ministry of Communications or a Brazilian court would invoke the doctrine of
vested right to insulate the existing terms of SMR licenses issued prior to July
20, 1996, from the reduced duration periods of SMR licenses as provided in the
Minimum Law.
    
 
   
     The Ministry of Communications has established comprehensive operating
standards and requirements applicable to SMR licensees. A license holder of SMR
channels is required to meet certain installation and minimum loading
requirements. Failure to comply with such requirements may subject the licenses
relating to such channels to revocation by the Ministry of Communications.
Certain SMR equipment must be installed within 12 months after receiving an SMR
license from the Ministry of Communications. Additional installation time may be
permitted if more than four repeater stations are being installed. The
installation time also may be extended in the discretion of the Ministry of
Communications if circumstances beyond the control of the licensee contribute to
the delay. Under proposed regulations released for public comment on May 16,
    
 
                                       72
<PAGE>   75
 
   
1997 ("Regulation No. 16"), the period for installation of the equipment would
be fixed in the proposal submitted to the Ministry of Communications by the
licensee, but no longer than 24 months from the date of issuance of the license.
Further, installation cannot be extended for longer than 6 months after the
agreed upon installation date. The Ministry of Communications requires each
channel to be loaded with 30 SMR radios within six months of the completion of
the installation, and with 70 SMR radios within four years of such date. McCaw
Brazil currently is not in compliance with applicable installation deadlines and
minimum loading requirements with respect to licenses covering 545 channels, all
of which are outside of Sao Paulo. Requests for extensions of the relevant
deadlines have been filed with the Ministry of Communications, except for
channels where McCaw Brazil failed to comply with applicable installations
requirements due to television frequency interference, for which extensions were
granted automatically by statute. No responses, however, have been received to
date with respect to such requests. There can be no assurance that the Ministry
of Communications will not take action in response to such failure to comply
which would have an adverse effect on McCaw Brazil.
    
 
   
     Under the regulations of the Ministry of Communications, an SMR license is
not transferable before the installation of the SMR system infrastructure is
completed and the transfer of a majority interest in a licensee is also
restricted until installation is completed. Under the proposed regulations
issued on June 25, 1997, the transfer may only be effected after the actual
commencement of commercial operation of service, except for transfers between
entities under common control. The transfer of the license or the controlling
interest of a licensee also requires prior authorization from the Ministry of
Communications. Under Decree No. 2197, however, a transfer of the controlling
interest in the licenseholder to a controlled or controlling company does not
require prior approval from the Ministry of Communications if such transfer is
by succession or as a result of a stock split. Sales of shares comprising less
than a majority interest may be made at any time, provided notification is
submitted to the Ministry of Communications within 30 days after the
effectuation of the transfer. The Ministry of Communications has not established
clear procedures governing the transfer of SMR licenses or the time frame within
which it may approve such requests for transfer.
    
 
   
     In Brazil, the transfer of control of an SMR licensee is subject to the
prior approval of the Ministry of Communications, except as noted above with
regard to stock splits. Because of these license transfer restrictions, McCaw
Brazil's interest in 1,180 of its 1,700 channels in Brazil is structured
pursuant to a number of option agreements entered into with the shareholders of
the respective corporate licensees of such channels. Pursuant to the Option
Agreements, McCaw Brazil has acquired a minority interest in each such licensee
not exceeding 49% and holds the option to acquire the balance of the ownership
interest in each such licensee upon the payment of an option exercise price. The
closing of each such option would be conditioned upon securing the approval of
the Ministry of Communications for the transfer of control of the relevant
licensees. The aggregate amount of the exercise price if all the options are
exercised is not material. A licensee is not eligible to request approval for
change of control until system installation has been completed, and many of the
channels that are the subject of the Option Agreements have not been installed.
The Company is currently conducting analog SMR system installation with regard
to a significant portion of the channels that are the subject of the Option
Agreements. While the Company believes it will receive Ministry of
Communications approval when it has met the installation requirements, no
assurance can be given that such approval will be obtained. Under the proposed
regulations issued on June 25, 1997, the transfer may only be effected after the
actual commencement of commercial operation of service. To the extent the
Company is not able to exercise its option to acquire the balance of the
ownership interest in a particular licensee, the Company believes that AirLink
would be able to continue to maintain its contractual right to manage the
operations subject to the license held by such licensee pursuant to a service
agreement and receive fees under such service agreement. However, the Company
would not own such license and the Company's rights with respect to such license
could be limited. There can be no assurance that the Ministry of Communications
would not challenge the validity of such service agreements. All of McCaw
Brazil's channels in Sao Paulo are indirectly owned entirely by the Company and
are not held pursuant to Option Agreements.
    
 
     The Company owns or has options to acquire multiple channels in each of its
service areas in Brazil, which have been acquired from private parties rather
than the Ministry of Communications. Under Administrative Ruling No. 478, one
entity may not "receive" more than one SMR license in a given service area. Such
ruling also provides that an entity may not receive an SMR license if such
entity is a member of a
 
                                       73
<PAGE>   76
 
commonly controlled or commonly managed group where another member of such group
already holds a license in the same service area. The Company believes that
Administrative Ruling No. 478 does not restrict an entity from acquiring prior
to July 13, 1994 more than one license in the same service area from private
parties and holding such licenses directly or indirectly.
 
   
     Administrative Ruling No. 478 also is unclear as to whether, in the event
of a transfer of multiple licenses, it would be permissible to consolidate such
licenses under the ownership of one entity. In any event the Company believes
that any limitation on acquiring or holding multiple SMR licenses in the same
service area or consolidation of multiple licenses would not affect those
licensees who held SMR licenses prior to July 13, 1994, the effective date of
Administrative Ruling No. 478. All of McCaw Brazil's licenses in Sao Paulo were
issued prior to July 13, 1994. There can be no assurance that the Ministry of
Communications will approve transfers of majority control of licensees in the
same service area. Furthermore, Decree No. 2197 effective April 9, 1997 provides
that any transfers of control can only occur after the period of time
established in rules to be issued by the Ministry of Communications.
Notwithstanding Ruling No. 478, proposed Regulation No. 16 would prohibit the
performance of SMR services in the same service area by an affiliate, a
controlled or controlling entity of an existing licensee or by a licensee that
is already the holder of an SMR license in the same service area. Any failure to
approve such transfers could have a material adverse effect on the Company.
    
 
     Any Brazilian company headquartered in Brazil is eligible to obtain
licenses to operate SMR services and there are no limitations on foreign
ownership of such companies. However, under Decree No. 2197, licenses can only
be obtained pursuant to a public bid.
 
   
     Brazil has recently made efforts to restructure its telecommunications
laws. The adoption of the Minimum Law, which is designed to rationalize
telecommunications services, including SMR, is an example of such efforts. The
Minimum Law provides that telecommunications services should be provided in such
a manner as to ensure interconnectivity, interoperability, fair competition
among service providers and equitable use of telephone numbers. In addition, the
Minimum Law requires public telecommunications service providers to allow for
interconnection of their networks with mobile cellular service networks. McCaw
Brazil is in the process of negotiating interconnection agreements with relevant
parties. Under Decree No. 2197, an SMR licensee may interconnect with the public
telecommunications network system at any convenient point of interconnection in
its service area. The General Law, however, revokes Article 12 of the Minimum
Law, which guaranteed SMR licensees the right to interconnect with the public
telecommunications network, and provide that interconnection for SMR services
will be subject to regulation by the Ministry of Communications or the newly
created regulatory agency.
    
 
     The Government of Brazil received on April 7, 1997, bids for the auction of
Band B cellular licenses covering ten areas throughout Brazil, including Sao
Paulo and Rio de Janeiro. On January 13, 1997, the Ministry of Communications
released the Band B Rules, which contain a provision prohibiting the initiation
of operations by certain other mobile telecommunications service providers in
the areas covered by the Band B licenses until December 31, 1999. It is unclear
whether this provision of the Band B Rules will prevent the Company from
providing iDEN-based ESMR services in Brazil before December 31, 1999. The
Company does not believe that the Band B Rules are applicable to its current SMR
operations in Brazil. There can be no assurance, however, that either the
Ministry of Communications or companies bidding for the Band B licenses will not
attempt to prevent the Company from offering ESMR services before December 31,
1999. In addition, companies bidding for the Band B licenses may request that
the December 31, 1999 date be extended or seek clarification as to the
applicability of the Band B Rules to iDEN-based ESMR services. Any significant
delay in offering ESMR services would have a material adverse effect on the
Company's competitive position in Brazil and on its business and results of
operations.
 
   
     On April 26, 1997 and in the beginning of June 1997, news reports appeared
in Brazilian newspapers and international wire services that an anonymous source
had forwarded to the Ministry of Communications a copy of the Company's offering
memorandum prepared in connection with the Initial Offering and a letter
alleging that the Company was operating in Brazil without authorization from the
Ministry of Communications. Based upon these allegations, the Ministry of
Communications sent to the Company a letter requesting its comments regarding
the allegations. On June 6, 1997, the Company sent to the Minister of Communica-
    
 
                                       74
<PAGE>   77
 
   
tions a letter in response to the allegations. Although the Company believes
that the current regulatory framework permits the operation of its existing
business in Brazil, there can be no assurance that the Ministry of
Communications will not modify the existing regulatory framework, or initiate
administrative proceedings, to impede the Company from providing the existing
SMR services or launching ESMR services. Further, certain members of the
Brazilian Congress introduced an amendment, which was enacted as part of the
General Law, to revoke Article 12 of the Minimum Law, which provided for
interconnectivity on a nondiscriminatory basis and guarantees the right of SMR
service providers, such as the Company, to interconnect with the public
telecommunications network. Any actions by the Ministry of Communications or the
Brazilian Congress 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.
    
 
   
     On June 25, 1997, the Ministry of Communications issued proposed
regulations for public comment. Regulation No. 20 of June 25, 1997 ("Regulation
20"), if approved as drafted, would impose limitations on the Company's ability
to obtain direct telephone numbers for all of its subscriber units and
interconnect with the public telecommunications network. Under Regulation 20,
the public service company must apply to the Ministry of Communications to
obtain blocks of telephone numbers to be used for the SMR services and the
telephone numbers granted by the Ministry of Communications cannot exceed 50
percent of the total number of SMR stations projected to be in operation, as
provided in the schedule for the deployment of the services. Within the SMR
network, the volume of traffic interconnected with the public telecommunications
network cannot exceed 33 percent of the total of the intra-network traffic
volume plus calls interconnected to the public telecommunications network. The
evaluation of the traffic volumes for the purposes of the above restrictions is
to take place on a quarterly basis. In connection with the transfer of licenses,
or of the controlling interest in SMR licensees, such transfers still must be
approved by the Ministry of Communications and may take place only after the
effective commencement of commercial operations of the service of the
transferee. Notwithstanding the proposed limitations, Regulation 20 may allow
for the licensee to hold more than one SMR license in the same geographic area
and to aggregate the channels corresponding to each such licenses under one SMR
license, subject to the prior approval of the Ministry of Communications.
    
 
     The purchase and sale of foreign currency in Brazil are subject to
governmental control. There are two foreign exchange markets in Brazil that are
subject to Central Bank regulations. The first is the commercial/ financial
floating exchange rate market which is reserved generally for: (i) trade related
transactions, such as import and export transactions; (ii) registered foreign
currency investments in Brazil; and (iii) certain other transactions involving
remittances abroad. The second is the tourism floating exchange rate market.
While both of these markets operate at floating rates freely negotiated between
the parties, the commercial/financial exchange market is restricted to
transactions which require prior approval of the Brazilian monetary authorities.
The purchase of currency for repatriation of capital invested in the country and
for payment of dividends to foreign shareholders of Brazilian companies is made
in the commercial/financial floating market.
 
   
     Provided that the original investment of foreign capital and capital
increases were registered with the Brazilian monetary authorities, there are no
significant restrictions on the repatriation of share capital and dividends.
Application has been made to register a substantial portion of the foreign
capital invested by McCaw Brazil and its subsidiaries with the Brazilian
monetary authorities. The majority of the capital of AirLink, the Brazilian
subsidiary through which any dividends are expected to flow, has been registered
with the Brazilian monetary authorities, and McCaw Brazil intends to structure
future capital contributions to Brazilian subsidiaries to maximize the amount of
share capital and dividends that can be repatriated through the Brazilian
monetary authority. There can be no assurance that McCaw Brazil can repatriate
share capital and dividends on foreign investments that have not been registered
with Brazilian monetary authorities. Dividends paid out of profits generated
after 1996 are currently not subject to withholding tax.
    
 
     Under current law, there is a 15% withholding tax on interest payment and
no withholding tax on dividends.

ARGENTINA
 
   
     The Company currently owns a 50% interest in McCaw Argentina. As a result
of the Argentina Transaction, the Company doubled its spectrum position, became
the largest SMR channel holder in Argentina, owning 820 SMR channels, which is
twice as many SMR channels as the second largest SMR operator and became the
holder of a nationwide paging business.
    
 
     Country Overview. With a population of approximately 34 million, Argentina
is the fourth most populous country in Latin America. In 1995, over 86% of the
country's inhabitants resided in urban areas and over 50% of the total
population resided in the three largest metropolitan areas: Buenos Aires
metropolitan area (11.3 million POPs), Cordoba (2.4 million POPs) and Rosario
(2.0 million POPs). Argentina is characterized by above-average income levels
relative to other Latin American countries and had a GDP per capita of
approximately $8,167 in 1995, the highest in Latin America. The high penetration
of passenger vehicles in Argentina, approximately 18 per 100 population, is
another indication of the relative wealth of Argentines and the demand for
mobile communications services.
 
     In 1991, the Argentine government implemented a stabilization and
structural reform program. Such efforts resulted in a sharp turnaround in
economic conditions. Real GDP growth accelerated to an average of approximately
5.0% a year from 1991 to 1996, up from .2% in the previous six years. The annual
rate of inflation declined to 1.6% in 1995 from 2,300% in 1990. The government
also carried out a substantial privatization program which included politically
sensitive sectors such as telecommunications, public utilities, oil, railroads,
provincial banks and the pension system.
 
     The Argentine government was the first Latin American government to issue a
cellular license to a private entity. In July 1988, the Secretary of
Communications granted the first cellular license to Movicom.
 
     Despite the relative maturity of the Argentine cellular market, it is one
of the fastest growing cellular markets in Latin America. From 1994 to 1995,
cellular subscribers grew 79%, reaching approximately 418,000 at the end of
1995, at which time, cellular penetration levels reached 2.6% in Buenos Aires,
 .5% in the northern and southern interiors, and 1.3% for the entire country, as
compared to 12.8% cellular penetration in the United States. Strong cellular
growth is expected to continue, with 2.3 million projected subscribers
nationwide by 2000, reflecting a penetration rate of 6.2% for the entire
country. On a regional basis, Buenos Aires is projected to reach 10.6% market
penetration by the year 2000 and account for 65% of Argentina's total subscriber
base. At a monthly average of $130, Argentina's revenue per cellular subscriber
is one of the highest in Latin America. By comparison, average monthly revenue
per cellular subscriber is $51 in the United States.
 
     The SMR business in Argentina is underdeveloped compared to the U.S.
market. In 1995, there were approximately 12,200 SMR subscribers in Argentina (a
penetration rate of less than .04%), compared to over 18 million SMR subscribers
in the United States (a penetration rate of 7.0%). Argentina's monthly average
revenue per SMR subscriber is approximately $50 compared to $16 in the United
States.
 
     Operating Company Overview. McCaw Argentina has 180 SMR channels (9 MHz) in
Buenos Aires, 200 SMR channels (10 MHz) in each of Cordoba, Rosario and Mendoza
and an additional 20 SMR channels in each of Mar del Plata and Tucuman. The
Company believes its channel position will allow McCaw Argentina to compete more
effectively with other wireless communications providers. McCaw Argentina also
operates a nationwide paging business with approximately 4,000 subscribers under
a nationwide paging license.
 
     In February 1997, McCaw Argentina launched commercial SMR service in Buenos
Aires. The company intends to begin offering commercial SMR service in Cordoba,
Mendoza and Rosario during the second quarter of 1997.
 
     McCaw Argentina plans to construct a digital ESMR network in Buenos Aires,
Cordoba, Rosario and Mendoza utilizing Motorola's iDEN technology. The company
expects to launch commercial ESMR service later in 1998. While migrating its
analog customers to the digital network, the company intends to operate parallel
digital and analog networks. As part of the migration process, the company will
encourage its higher usage customers to convert to the digital network so they
can benefit from the broader range of service
 
                                       76

offerings. Digital service offerings will include interconnect services,
dispatch radio and paging using one multi-functional handset. Initially, the
company will target the mobile workforce, which it believes will be the most
likely users of iDEN's integrated service offerings.
 
     McCaw Argentina currently offers analog dispatch and interconnect service
utilizing both Motorola and Ericsson equipment. Service offerings include
private call, call alert and scanning. The company plans to differentiate itself
from other SMR providers by offering superior voice quality, providing extensive
service coverage and maintaining a high level of customer service. The company
has a centralized customer service and installation center located in Buenos
Aires.
 
     The company's SMR service is designed to be a business tool for the mobile
workforce. The company intends to focus its marketing efforts on businesses that
have a need for mobile communications such as trucking and transportation
companies, real estate firms, construction companies, suppliers and distributors
and security companies. McCaw Argentina is in the process of developing a
distribution network and believes a strong direct sales force is essential to
reaching potential business customers. The company is currently building a
direct sales force and expects to have 26 direct sales representatives by the
end of 1997. In addition, the company has contracted with independent dealers to
market McCaw Argentina's products and is providing extensive training to each of
its distribution channels in order to ensure a high level of customer
satisfaction. The company expects 25% of new customers will be added through
independent dealers.
 
     McCaw Argentina will offer multiple pricing plans tailored for the business
user and will maintain broad flexibility on its pricing decisions. Unlike many
of its competitors, McCaw Argentina sells its SMR handsets instead of leasing
them. The sale of handsets provides a more stable revenue stream and tends to
reduce customer churn. Currently, the average retail price for an analog handset
is $429.
 
     To establish brand identity, the company has begun a promotional
advertising campaign which targets the business segment of the market. In
addition to advertising, the company initially will rely heavily on its direct
sales force to educate potential customers on the benefits of using McCaw
Argentina's service.
 
     McCaw Argentina is headquartered in Buenos Aires. As of December 31, 1996,
McCaw Argentina had 23 employees.
 
   
     Operating Company Subsidiaries. The following are subsidiaries of McCaw

     McCaw Argentina S.A. holds trunking licenses for Buenos Aires, Cordoba,
     Mendoza and Rosario and shares management and operations, including billing
     and selling of handsets, with Airlink S.A. The Company plans to transfer
     the management and operations functions currently performed by Airlink S.A.
     to McCaw Argentina S.A.
    
 
   
          - Buenos Aires Trunking S.A. Incorporated in Buenos Aires on September

     Competition. The two largest SMR providers in Argentina, as measured by
subscribers, are owned by Movicom and Miniphone S.A. ("Miniphone") (the two
cellular providers in Buenos Aires) and operate under the tradenames "Movilink"
and "Starcom," respectively. Movicom owns 100 channels in Buenos Aires and 40
SMR channels in each of the three other major cities. In addition to operating
various SMR networks, Movicom also operates an iDEN-based system in Buenos
Aires. Movicom's iDEN system utilizes the higher capacity "first-generation"
voice algorithm system. Movicom has an arrangement with Motorola that gives it
 
                                       77
<PAGE>   80
 
exclusive use of iDEN in Argentina until September 15, 1997. Based on
discussions between the Company and Motorola, the Company does not believe that
this exclusivity period will be extended. Starcom owns and operates 60 channels
in Buenos Aires and additional SMR channels in two other major cities. There are
two cellular service providers in each of the major markets in Argentina. In
Buenos Aires, the two service providers are Movicom (a joint venture among
BellSouth Corporation, Motorola and others) and Miniphone (a joint venture among
the two Argentine telephone companies, Telefonica de Argentina S.A. and Telecom
Argentina STET-France Telecom S.A.). Over 300,000, or 70%, of Argentina's
cellular subscribers are located in Buenos Aires. In the northern region of
Argentina, the two service providers are Compania de Telefonos del Interior S.A.
("CTI") (a joint venture that includes GTE and Lucent Technologies) and Telecom
Personal S.A. (a wholly owned subsidiary of Telecom Argentina STET-France
Telecom S.A.). In the southern region of Argentina, the two service providers
are CTI and Telefonica Comunicaciones Personales S.A., a wholly owned subsidiary
of Telefonica de Argentina S.A., which operates under the name UNIFON.
 
     The Company expects additional competition following the auction of PCS
licenses and the auction of an additional 220 SMR channels in Buenos Aires and
other major cities, which are expected to occur during 1997.
 
     Partner Description. The Company and WVA each own 50% of McCaw Argentina.
 
     Regulatory and Legal Overview. The Comision Nacional de Comunicaciones
("CNC") and the Secretary are the Argentine telecommunications authorities
responsible for administration and regulation of the SMR industry.
 
     CNC regulations require SMR operators to build-out their channels within 12
months of the channel authorization issuance if the system is multi-site and to
guarantee their performance by posting a bond equivalent to the price paid in
the spectrum auction. The bond is released once the installation and activation
of the SMR site or sites have been verified by the CNC. McCaw Argentina S.A. has
built out its channels in a timely fashion and the bonds posted by McCaw
Argentina S.A. and WVA in connection with its build-out obligation have expired
and are not required to be replaced.
 
   
     SMR licenses have an indefinite term, but are subject to revocation for
violation of applicable regulatory rules as discussed below. SMR service must
commence within six months to one year after receipt of the channel assignment
(depending on the type of network configuration). Failure to meet service or
loading requirements can result in revocation of the channel authorizations. The
CNC will revoke the licensee's license upon the finding of a third breach by a
licensee of service requirements. Licenses and channel authorizations may be
revoked for violation of other regulatory authority rules and regulations. All
SMR channel holders, including McCaw Argentina S.A. and WVA's Argentine
subsidiaries, that received their channel authorizations pursuant to the
November 1995 SMR auction were granted an extension to December 1997 from the
original December 1996 deadline to meet initial loading requirements. The
Company has been loading subscribers to its analog SMR network since the
commencement of service in February 1997 and expects to meet the initial loading
requirements by the deadline. Argentina imposes no limitation on foreign
ownership of SMR licenses.
    
 
     SMR providers are assured unlimited interconnect pursuant to the terms of
the tender rules under which the channels were awarded, as well as pursuant to
applicable laws. Furthermore, interconnection with the public switched telephone
network must be on a nondiscriminatory basis. McCaw Argentina S.A. is in the
process of negotiating interconnect agreements with the applicable parties.
 
     Under current law, Argentine currency is convertible into U.S. dollars
without restrictions, and Argentina has a free exchange market for all foreign
currency transactions.
 
     Under applicable Argentine corporate law, dividends may be paid only from
liquid and realized profits as shown on the company's financial statements
prepared in accordance with Argentine generally accepted accounting principles.
Five percent of such profits must be set aside until a reserve equal to twenty
percent of the company's capital stock has been established. Subject to these
requirements, the balance of profits may be declared as dividends and paid in
cash pursuant to a majority vote of the shareholders. Under current law, there
is a 13.2% withholding tax on interest payments and no withholding taxes on
dividends.

MEXICO
 
   
     The Company owns an approximately 48.1% equity interest in Mobilcom.
Mobilcom is the largest SMR service provider in Mexico.
    
 
     Country Overview. Mexico is the second most populated country in Latin
America, with a population of 92 million. Mexico's population is 75% urban, and
approximately 18 million people, or more than one-fifth of the country's total
population, reside in the Mexico City metropolitan area. Other major
metropolitan population centers include Guadalajara (3.4 million POPs) and
Monterrey (3.1 million POPs). In addition, Mexico's income level is above
average relative to other countries in Latin America.
 
     The Mexican government's fiscal and monetary policies since the 1994 peso
devaluation have been credited with preventing a deeper economic crisis and have
stabilized the country's economic recovery. After contracting 6.2% in 1995, the
economy is expected to grow 4.4% in 1996 and nearly 5.9% in 1997. Inflation is
estimated to have fallen to 27.0% in 1996 from 52.0% in 1995, and is projected
to decline to 17.0% in 1997.
 
     Mexico has a relatively low teledensity, with approximately 9.2 lines per
100 inhabitants. Mexico's cellular market is the second largest in Latin America
based on the number of subscribers, but with a penetration rate of 0.8% in 1995,
cellular penetration in the Mexican market is still significantly below the U.S.
cellular penetration rate of 12.8% and the Latin American cellular penetration
rate of 1.3%. In a country where fewer than 10 out of every 100 inhabitants have
a telephone line, cellular telephony can serve as a landline substitute.
 
     Mexico has experienced very rapid growth in the number of wireless
subscribers. Over the last five years, annual growth has averaged 62%. Cellular
subscribers are projected to grow from 686,000 at the end of 1995 to
approximately 2.9 million at the end of 2000, an annual growth rate of 33%. The
principal factor driving demand over the next five years will be the expected
accelerated growth of the Mexican economy. By 2000, cellular penetration in
Mexico is expected to reach 3.5%. Currently, over 48% of cellular subscribers in
Mexico are located in Mexico City.
 
     Mexico has an SMR penetration rate of approximately .05%. Unlike many SMR
providers, the company sells the majority of its handsets instead of leasing
handsets. The average revenue per subscriber per month for cellular and SMR in
Mexico is $78 and $19, respectively, which is higher than the average monthly
U.S. revenue for cellular $51 and for SMR $16.
 
     Operating Company Overview. Mobilcom began commercial SMR operations in
September 1993 under the brand name "Tricom." Mobilcom, through its subsidiaries
and management agreements, provides SMR services in 15 cities and along a number
of major highways. As of December 31, 1996, the company had approximately 24,000
subscribers. The cities in which Mobilcom, through its subsidiaries and
management agreements, holds SMR licenses include: Mexico City (with a total of
204 channels representing approximately 10 MHz), Guadalajara (with a total of 60
channels) and Monterrey (with a total of 25 channels). As of December 31, 1996,
Mobilcom had 43 transmitter sites. Mobilcom has deployed Motorola, Uniden, Nokia
and General Electric technology in its analog SMR networks.
 
     Mobilcom initially intends to construct a digital ESMR network in Mexico
City utilizing Motorola's iDEN technology. The company expects to launch
commercial service on its digital ESMR network later in 1998. While migrating
its analog customers to the digital network, the company intends to operate
parallel digital and analog networks, but within two years of commercial
implementation of ESMR services the company anticipates all of its customers
will be migrated to digital. As part of the migration process, the company will
encourage its higher usage customers to convert to the digital network so they
can benefit from the broader range of service offerings. Digital service
offerings will include interconnect services, dispatch radio and paging using
one multi-functional handset. Initially, the company will target the mobile
workforce which it believes will be the most likely users of iDEN's integrated
services.
 
     Mobilcom's assets also include 1,040 channels in the 400 MHz frequency band
covering central and northern Mexico. Mobilcom currently is considering a sale
of its 400 MHz channels because this frequency is not central to Mobilcom's
business plan. In addition, Mobilcom is building a digital microwave network
 
                                       79
<PAGE>   82
 
   
throughout central and northern Mexico to provide regional dispatch radio
services. The Company is also contemplating leasing excess capacity on its
digital microwave network to one or more of the recently licensed long distance
providers in Mexico, including Telecomunicaciones Globales, S.A. de C.V., a
company in which the Company holds a 13% equity interest ("Globales"). Mobilcom
and Globales have entered into certain arrangements pursuant to which Globales
leases access to Mobilcom's microwave network.
    
 
     In 1995 and 1996, Mobilcom experienced high rates of churn (reaching an
average of 3.7% per month over the two-year period) which the Company believes
was caused primarily by the economic downturn in Mexico. Further, the company
suffered from a high level of bad debt expense. To address these problems,
Mobilcom's board of directors appointed a new chief operating officer in the
fourth quarter of 1996. The primary short-term objectives of the company are to:
(i) implement a plan to reduce overall operating expenses; (ii) build a high
quality customer base and focus on maximizing profitability rather than building
market share; and (iii) establish a high level of customer service, comparable
in quality to the customer service provided by wireless communications companies
in the United States.
 
     Mobilcom offers its customers a broad range of services and pricing plans
designed to meet the specific needs of its customers. Mobilcom offers dispatch
only and integrated service plans (dispatch and interconnect). These plans
include sale or rental of various models of handsets. The basic price package
consists of a monthly fee and interconnect and dispatch charges depending on
minutes of use.
 
   
     Mobilcom's sales and marketing efforts focus primarily on providing
cost-effective local and regional dispatch radio services to its target
customers, which are businesses engaged in manufacturing and distribution.
Mobilcom markets its services through a multichannel distribution network
including direct sales representatives and independent dealers. Direct sales
representatives account for 40% of new customers and distributors account for
60%. In the future, the company expects to increase sales through the
distributor channel because it believes this channel will be the most effective
in targeting small businesses.
    
 
   
     Mobilcom is headquartered in Mexico City and has branch offices in
Guadalajara, Monterrey and Tijuana. As of December 1996, Mobilcom had
approximately 150 employees in Mexico.

     Competition. Mexico currently has only 85,000 commercial SMR subscribers,
compared to more than 18 million in the United States. Mobilcom is the largest
SMR provider in Mexico, both in terms of channels and subscribers. The Mexican
cellular market is divided into nine regions and there are two cellular licenses
per region. Telefonos de Mexico, S.A. de C.V. ("Telmex"), Mexico's national
telephone company, has a nationwide cellular license. In the Mexico City region
and throughout most of the southern portion of Mexico, the second cellular
carrier is Iusacell, S.A. de C.V. (a joint venture between Bell Atlantic and
Grupo Iusacell). In the northern part of Mexico, cellular carriers include
Movitel, Cedetel and Baja Cellular Mexicana. Poctatel del Sureste is also active
in Southern Mexico.
    
 
     As part of its drive to improve and increase Mexican telecommunications
services, the Mexican government has announced its intention to auction a number
of licenses to provide wireless communications services, including licenses for
dispatch services in the 900 MHz frequency band, for narrowband dispatch
services in the 220 MHz frequency band and PCS. Such auctions, which are
anticipated to occur during 1997, will increase the number of actual and
potential competitors that Mobilcom will face.
 
   
     Partner Description. The Company's strategic partners in Mobilcom include
Grupo San Luis, WVM and Associated SMR, which hold approximately 21%, 11.6% and
11.3% interests, respectively. The remaining interests in Mobilcom are held by
the Carlyle Group, one smaller shareholder and a number of individuals.
    
 
     Regulatory and Legal Overview. The Secretary of Communications and
Transportation regulates the telecommunications industry in Mexico. Since early
1994, the Mexican government has been deregulating the telecommunications
industry in order to improve the quality and expand the coverage of
telecommunications services. The Mexican government has stated its intention to
increase competition within the telecommunication industries and its desire to
attract foreign investment for the purpose of improving Mexico's
telecommunications infrastructure. Mexico's Federal Telecommunications Law (the
"Mexican Federal Telecommunications Law"), which became effective in June 1995,
outlines the broad rules for opening the local and long distance service markets
to competition.
 
     The Mexican Federal Telecommunications Law requires that all
telecommunications licenses (referred to as "concesiones" in Mexico) must be
owned by entities that do not have more than 49% of their voting
 
                                       81
<PAGE>   84
 
   
equity interest owned by non-Mexican entities. Although such 49% limitation
existed prior to the enactment of the Mexican Federal Telecommunications Law for
certain types of telecommunications licenses, SMR licenses issued prior to the
effectiveness of the legislation could be owned by entities wholly owned by
non-Mexicans. Mobilcom believes that in accordance with the terms of the Mexican
Federal Telecommunications Law and Mexican constitutional law principles, the
49% limitation on non-Mexican participation does not apply to the SMR licenses
in which it had an interest at the time of the effectiveness of the Mexican
Federal Telecommunications Law. Consistent with this view, in May 1996, the
Mexican Secretary of Communications and Transportation amended all of the 800
MHz SMR licenses issued prior to the effective date of the Mexican Federal
Telecommunications Law in which Mobilcom had an interest to delete a provision
limiting non-Mexican participation to 49%. Accordingly, all of Mobilcom's 800
MHz SMR licenses, except for one license covering 10 channels along a major
highway from Mexico City to Guadalajara, were amended to remove the 49%
foreign-ownership limitation. The provisions of the Mexican Federal
Telecommunications Law restricting foreign ownership of telecommunications
licenses may, however, have an impact on future acquisitions of licenses by
Mobilcom, including licenses for channels needed to build-out digital mobile
networks in Mexico, and renewal of existing licenses. Although licenses to
provide cellular services are also subject to the 49% limitation on foreign
ownership, the Mexican Federal Telecommunications Law explicitly provides for a
waiver procedure of such limitations for cellular providers upon receipt of a
favorable opinion from the Mexican National Foreign Investments Commission.
    
 
     The Mexican Federal Telecommunications Law provides all wireless services
providers with the right to interconnect to the public switched network operated
by Telmex. Mobilcom has entered into an interconnection agreement with Telmex
and currently provides interconnection services through Telmex to a limited
number of its subscribers. Mobilcom plans to increase subscriber interconnection
significantly as it upgrades its SMR network.
 
     Mexican companies may remit dividends and profits outside of Mexico if the
Mexican company meets certain distribution and legal reserve requirements. A
Mexican company must distribute 10% of its pretax profits to employees and
allocate 5% of net profits to the legal reserve until 20% of the stated capital
is set aside. Although the Company's investment in Mobilcom is registered with
the Mexican National Registry of Foreign Investments, registration is no longer
a prerequisite for the remittance of dividends and profits outside of Mexico.
Under Mexican corporate law, approval of a majority of shareholders of a
corporation is required to pay dividends. Dividends paid by Mobilcom to its U.S.
shareholders are subject to a 10% withholding tax unless Mobilcom chooses to pay
the Mexican corporate income tax on the net earnings from which the dividends
are being paid. Interest paid by Mobilcom to U.S. residents is subject to a 10%
withholding tax.
 
PHILIPPINES
 
   
     In August, 1996, McCaw International acquired a 30% equity interest in
Infocom, a company organized under the laws of the Republic of the Philippines.
Infocom owns nationwide licenses (with a total of 100 channels representing
approximately 5 MHz), to provide SMR, ESMR and paging services. Infocom began
commercial service of its paging network in February 1995 under the brandname
"Infopage" and plans to begin commercial service of an iDEN-based ESMR network
by the end of 1997.
    
 
     Country Overview. The Philippines has a population of approximately 67
million people and population density of 228 people per square kilometer,
compared to a population density of 29 people per square kilometer in the United
States. The principal cities include Manila, Quezon City, Davao City, Caloocan
City and Cebu City. The country has experienced strong economic growth. In 1995,
GDP increased by 4.8% and by 4.3% in 1994.
 
     The Philippines has one of the lowest teledensities in Southeast Asia, with
approximately one line per 100 inhabitants. It is estimated that only 45% of
total demand has been satisfied. Further, metropolitan Manila, the country's
most urban area, has 80% of all telephone lines with approximately two per 100
inhabitants. The waiting list for landline telephone service contains
approximately 800,000 names and it can take nearly nine years to get a landline
telephone. Current efforts to increase landline installation are expected to
bring teledensity to ten lines per 100 inhabitants by the year 2000.
 
                                       82
<PAGE>   85
 
     The demand for wireless telephone services has grown significantly,
principally due to low teledensity, competition and rising income levels
resulting from strong economic growth in the country. In 1994 and 1995 the
market for wireless services grew by nearly 110% and 150%, respectively. Despite
this growth, the Philippines has one of the lowest cellular penetration rates in
Southeast Asia at .5%. Comparatively, Singapore and Malaysia have penetration
rates of 10.0% and 5.0%, respectively. Currently, there are more than 500,000
cellular subscribers nationwide, with most of this base concentrated in
metropolitan Manila. The continuing economic prosperity in the Philippines is
expected to drive the demand for wireless services over the next decade.
According to industry estimates, the number of cellular subscribers should grow
at a compounded annual rate of 47% to reach 3.3 million subscribers, or a 4.4%
penetration rate, by the end of the decade.
 
     The Philippine paging market has experienced substantial growth over the
past few years. From 1993 to 1995, paging subscribers grew 202%, reaching
325,000 subscribers at the end of 1995. Despite the rapid growth of the
Philippine paging market, it remains largely underdeveloped with a penetration
rate of only .5%. Strong paging growth is expected to continue, with 1.4 million
paging subscribers projected in the year 2000, reflecting a five year compound
annual growth rate of 35% and a penetration rate of 1.8%. The Philippine SMR
market is underdeveloped as well, with only 18,000 SMR subscribers at the end of
1995, or a penetration rate of .03%.
 
     Operating Company Overview. Infocom commercially launched paging services
in February 1995 under the brand name "Infopage." The company has approximately
42,000 subscribers at December 31, 1996 and the Company believes that it was the
fourth largest paging company in the country. Infocom currently offers coverage
across metropolitan Manila and Subic Bay and expects to offer nationwide
coverage by the end of 1997.
 
     Infocom offers both alphanumeric and numeric paging services utilizing
Motorola's FLEX technology and differentiates itself from its competitors by
offering a variety of value-added services including secretarial services, voice
mail, call forwarding, fax mail and group call. Moreover, the company places
considerable emphasis on providing a high level of customer service through its
customer service center located at the company's headquarters in Manila. Unlike
many of its competitors, Infocom does not lease or rent its pagers and currently
its average retail sale price for alphanumeric units exceeds $250. The company's
monthly subscription rate for alphanumeric paging services is currently
approximately $12.
 
     Paging services in the Philippines are targeted at both the business and
consumer segments. Infocom has developed a comprehensive and diverse
distribution network and believes that such a diverse distribution mix will
contribute to an increased growth in its subscriber base. In order to capture
the consumer segment and create brand awareness, Infocom has ten owned and
operated retail outlets, primarily located within large shopping malls, that
exclusively carry the company's products. The company intends to expand this
channel to twenty retail locations by the end of 1997. To target the business
segment, the company has a direct sales force of 130 people, which it intends to
increase to 200 by the end of 1997. Finally, the company has contracted with ten
major dealers and 70 independent dealers to market Infopage's products. The
company expects this independent channel to grow to over 100 dealers by the end
of 1997.
 
     Infocom has a nationwide SMR license and is currently constructing a
digital ESMR network utilizing Motorola's iDEN technology. Infocom currently
does not have any ESMR subscribers, but expects to launch commercial ESMR
service in metropolitan Manila during 1997. In December 1996, Infocom signed an
equipment purchase contract with Motorola. At present, the company has acquired
12 of the 44 proposed radio cell sites and has begun construction of its switch
facility.
 
     Infocom's ESMR business will initially target the larger business customers
in its markets. The company intends to focus on building profitability rather
than building market share in a similar fashion to its efforts in its paging
business. Within the business segment, the company believes the mobile workforce
including construction, service, real estate and sales companies will be the
most likely users of iDEN's integrated service offerings.

     Although the company intends to fully utilize its established paging
distribution network and leverage Infopage's brand recognition, the company also
intends to substantially augment its direct sales force in order to effectively
target other business customers. The company has begun to formulate a strategy
for its pricing plans and aims to charge a premium to low usage subscribers and
a slight discount to high usage subscribers while offering a significantly
greater number of services.
 
     Infocom is headquartered in Manila. As of December 31, 1996, Infocom had
456 employees of which 320 were operators serving its paging customers. In
addition to designating three of the 11 members of Infocom's board of directors
as well as having one of its directors serve as an advisor to Infocom's
executive committee (which is a management committee that under Philippine law
may only have Philippine nationals as members), the Company has seconded two of
its managers as full time employees of Infocom with responsibility for leading
Infocom's marketing and technical efforts.
 
     Competition. There are two major SMR license holders in the Philippines,
each owning 100 channels nationwide, and 10 licensed paging operators. Infocom
believes that it is uniquely positioned to compete effectively in the
Philippines as a result of its nationwide SMR license and its fast-growing
paging business. In addition, the Joint Operating Agreement would enable Infocom
to jointly operate the largest SMR system in the Philippines. There are
currently five cellular providers with nationwide licenses in the Philippines,
two of which are AMPS operators, one of which is a TACS operator and two of
which are GSM operators. Pilipino Telephon Corporation ("Piltel"), the operator
of the public switched telephone network, is the largest cellular provider, with
over 50% market share. As part of its effort to improve teledensity, the
government requires cellular providers to meet certain landline buildout
requirements, which require the installation of 400,000 telephone lines. This
represents a significant investment for each of these providers. See
"-- Regulatory and Legal Overview."
 
     Partner Description. The Company's partners in Infocom include the Gotesco
Group, a leading diversified conglomerate engaged in retail, real estate,
banking, manufacturing and trading in the Philippines headed by Jose C. Go,
which owns a 20% interest in Infocom. Affiliates of AIG recently purchased a 10%
interest in Infocom from an existing Infocom shareholder at a significantly
higher implied valuation than that paid by the Company for its interest in
Infocom. Other shareholders include a 32% holder and an 8% holder.
 
     Regulatory and Legal Overview. In the Philippines, the telecommunications
industry is principally governed by Republic Act No. 7925 (the "Telecoms Act")
enacted on March 1, 1995. Under the Telecoms Act, the National
Telecommunications Commission (the "National Commission"), an agency under the
Department of Transportation and Communications, is mandated to regulate the
telecommunications industry.
 
     Engaging in telecommunications operations requires a franchise from the
Philippine Congress, which is the country's legislative body. After securing a
Congressional franchise, a franchise holder must apply to the National
Commission for an operating license called a Certificate of Public Convenience
and Necessity ("CPCN"). The grant of a CPCN goes through a process of public
notice and hearing. After receipt of an application for a CPCN for a particular
telecommunications service, and pending its legal, technical and financial
evaluation through a public hearing, the National Commission will initially
issue a Provisional Authority ("PA"), which serves as a temporary operating
permit for the particular telecommunications services applied for. Pursuant to
the PA an applicant can commence construction and commercial operations.
Infocom's PA authorizes it to operate a nationwide digital trunked radio
dispatch communications system. It is subject to revocation for failure to (i)
operate continuously for two years or (ii) commence operations within two years
of the issuance of the PA. Pursuant to Infocom's PA, as amended, it is required
to commence operations by January 20, 1998.
 
     The Telecoms Act provides that a telecommunications entity with regulated
types of services must make a public offering of at least 30% of its aggregate
common stock within a period of five years from the effective date of the
Telecoms Act or the entity's first start of commercial operations, whichever
occurs later. Accordingly, Infocom is mandated to make a public offering of 30%
of its common stock by March 1, 2000.
 
                                       84
<PAGE>   87
 
     Under Philippine law, foreign entities' direct ownership of a public
utility telecommunications company is limited to 40% of the company's capital
stock. Philippine law also limits the participation of foreign investors in the
governing body of any public utility enterprise to their proportionate share in
its capital; therefore, a foreign investor's participation in the management of
a telecommunications company is limited solely to membership on its board of
directors. Accordingly, all the executive and managing officers (e.g.,
president, chief executive officer, treasurer) are required to be citizens of
the Philippines.
 
     Presidential Executive Order No. 59 (1993) prescribes, as a matter of
national policy, for the compulsory and nondiscriminatory interconnection of
authorized public telecommunications carriers. Interconnection is negotiated and
effected through bilateral negotiations between the parties involved subject to
certain technical/operational and traffic settlement rules of the National
Commission. Infocom is discussing an interconnection agreement with Piltel.
 
     Presidential Executive Order No. 109 Series of 1993, and, subsequently, the
Telecoms Act (as implemented by the National Commission's Memorandum Circular
No. 8-9-25) require cellular mobile operators to install at least 400,000 local
exchange lines. The Company does not believe that Infocom is subject to such
requirement, however, there can be no assurance that this will be the case. If
this requirement were found to be applicable to Infocom, it would require a
significant capital investment.
 
     Under current regulations of the Central Bank of the Philippines (the
"Central Bank"), foreign exchange may be freely sold and purchased outside the
Philippine banking system. Restrictions exist on the sale and purchase of
foreign exchange in the banking system. The Philippine monetary authority, with
the approval of the President of the Philippines, has the statutory authority,
during a foreign exchange crisis or in times of national emergency, to
temporarily suspend or restrict sales of foreign exchange, require licensing of
foreign exchange transactions or require delivery of foreign exchange in the
Central Bank or its designee.
 
     Foreign investments need not be registered with the Central Bank. The
registration of a foreign investment with the Central Bank is only required if
the foreign exchange needed to service the repatriation and the remittance of
capital and dividends are to be sourced from the Philippine banking system.
Nevertheless, even without Central Bank registration, foreign exchange needed
for capital repatriation and remittance of dividends of unregistered investments
can be sourced lawfully outside of the Philippine banking system. The Company's
investment in Infocom has been registered with the Central Bank.
 
     Under current law there is a 15% withholding tax on dividends and a 20%
withholding tax on interest payments.
 
SHANGHAI, PEOPLE'S REPUBLIC OF CHINA
 
     The Company currently has a contractual right to receive 25.2% of the
profits generated by the Shanghai GSM System, which is operated by Unicom. The
Shanghai GSM System covers the greater Shanghai area comprising over 14 million
POPs. Unicom is one of only two licensed cellular operators in Shanghai. See
"-- Corporate Governance -- China."
 
     Country Overview. With a population of approximately 1.2 billion, the
People's Republic of China is the most populous country in the world and the
third largest behind Russia and Canada in terms of geographic size. Shanghai is
one of China's leading cities. It is one of four cities in China which has been
accorded provincial level status and also has the largest port in China. The
city covers an area of over 6,000 square kilometers and has a population of
approximately 14 million. Shanghai's GDP experienced a growth rate approaching
15% per year in both 1993 and 1994, and its GDP per capita was $1,303 in 1995,
over two times the national average of $517.
 
     In 1990, the State Council approved the establishment of a new economic
trade zone in the "Pudong New Area" section of Shanghai. The Pudong New Area is
similar to China's Special Economic Zones, which have been established to
attract foreign investment, and is expected to be the region's primary
international business conduit.
 
                                       85

     The demand for telecommunications services continues to grow and
teledensity remains at one of the lowest levels in the world at less than one
line per 100 inhabitants. China was the fifth largest cellular market in the
world in 1995, with over 3.7 million subscribers, and was the second largest
paging market in the world with over 26.1 million subscribers. The cellular
market has grown at a compounded annual growth rate of 175% over the last 5
years. Although China has one of the lowest cellular penetration rates in the
world at .3%, its cellular penetration rate is expected to reach 2% by the end
of the decade.
 
     Operating Company Overview. The Shanghai GSM System is a cooperative
project established by Unicom and SSTIC to construct and operate a GSM cellular
network in Shanghai. The Shanghai GSM System has grown quickly since the
commencement of commercial operations in July 1995 and as of December 31, 1996
had approximately 28,000 subscribers. The current network has 55 cell sites
covering the greater Shanghai region (including the Pudong New Area). Under the
current laws of the People's Republic of China, foreign investors are not
permitted to be involved directly in the ownership or operation of
telecommunications services. In the event that such laws change, the Company may
seek to convert its contractual right to share profits generated by the Shanghai
GSM System to a direct ownership interest, although there can be no assurance
that this would be possible.
 
     In August 1995, the Company formed a joint venture with SSTIC called
Shanghai McCaw pursuant to which the Company provided financial support to the
Shanghai GSM System for construction of the initial phases of the system in
exchange for a contractual right to share profits from the system with SSTIC.
Through its joint venture arrangements, the Company provides advice and
direction to the Shanghai GSM System in the key areas of engineering, customer
care, billing practices, quality assurance and system performance.
 
     Shanghai McCaw currently employs seven people. Of these seven employees,
the General Manager is an employee of McCaw International who has been seconded
to the joint venture. The remainder of the joint venture's personnel are native
Chinese.
 
     Shanghai McCaw initially provided technical advice to the Shanghai GSM
System during the construction phase of the network. Shanghai McCaw has
continued to provide technical support in the ongoing process of upgrading the
quality and coverage of the GSM network and has become increasingly involved in
supporting the development of a diversified sales and marketing plan to compete
with the systems operated by the Ministry of Post and Telecommunications (the
"MPT").
 
     Competition. There are only two authorized cellular providers in Shanghai,
Unicom and the Shanghai PTA (the local branch of the MPT). The Shanghai PTA has
been in operation since 1989 and operates three cellular networks (two TACS
systems and one GSM system).
 
     Partner Description. SSTIC, the Company's partner in Shanghai McCaw, is an
investment holding company which was established for the purpose of developing
the Shanghai high-technology industry. SSTIC was formed by the Municipal
Government of Shanghai, six major Shanghai banks as well as two major
diversified Shanghai conglomerates. SSTIC was one of the original shareholders
of Unicom.
 
     Regulatory and Legal Overview. Until 1994, the MPT was the sole entity
authorized to provide public telecommunications services in China. In July 1994,
the State Council established Unicom with the authority to provide public
telecommunications services. In addition, pursuant to a 1995 agreement the MPT
and the Peoples Liberation Army (the "PLA") agreed to jointly develop 800 MHz
cellular communications networks to provide wireless communications services to
the public using spectrum originally allocated to the PLA for military
communications use. Accordingly, there are three entities in China authorized to
provide cellular telecommunications services to the public. The MPT continues in
its role as the central government's regulatory authority over the
telecommunications sector.
 
     Under current Chinese law, foreign investors are not permitted to be
involved directly in the ownership or operation of telecommunications services.
 
     Renminbi, the currency of China, is not freely convertible. The stated goal
of the government is to achieve full convertibility by the year 2000. Under
current laws, a foreign invested enterprise is permitted to convert its Renminbi
earnings to foreign currencies for the purpose of enabling its foreign investors
to receive
 
                                       86
<PAGE>   89
 
dividends and interest payments. Conversion of Renminbi to foreign currencies
for the purpose of repatriating foreign investors' capital contributions to, and
principal payments from, a foreign invested enterprise is subject to approval by
relevant government authorities, which approval will be granted upon showing
that the foreign invested enterprise has been lawfully terminated and dissolved
or the loan has been properly registered, as the case may be. The Company's loan
to Shanghai McCaw has been properly registered with the relevant governmental
authority. Under current law there is a 10% withholding tax on interest payments
and no withholding tax on dividends.
 
CANADA
 
   
     Operating Company Overview. The Company owns 1,596,067 shares of common
stock of Clearnet, a Nasdaq-listed company, representing approximately 3.7%
interest. On June 30, 1997, the Company's Clearnet common stock had a market
value of approximately $19 million. Clearnet is the largest SMR operator in
Canada as measured by the number of current subscribers, the number of 800 MHz
channels and the population of its service territory. As of December 31, 1996,
Clearnet provided analog SMR services in over 40 cities across Canada to
approximately 54,000 subscriber units and ESMR services in Ontario and Quebec to
approximately 5,000 subscriber units. In addition, Clearnet holds one of the two
national 30 MHz licenses to provide PCS in Canada. Clearnet plans to launch its
PCS network in Canada's largest urban centers in mid-1997.
    
 
   
     The Company has one representative on the Clearnet board of directors.
Nextel owns additional shares of common stock of Clearnet representing an
approximate 15.3% interest and also has one representative on the Clearnet board
of directors.
    
 
   
     On June 26, 1997, Nextel announced that it received the consent of the
holders of its public notes regarding certain amendments to the indentures
governing such notes. The Nextel noteholders agreed, among other things, to
permit Nextel to transfer its equity interest in Clearnet to McCaw
International. If Nextel effects such transfer, McCaw International will hold an
aggregate of 8,373,845 shares of Clearnet, representing approximately 19% of the
outstanding common stock of Clearnet, which represents a 1.7% voting interest.
Additionally, McCaw International will have the right to nominate an additional
director to Clearnet's board of directors. As of June 30, 1997, based on the
closing price of Clearnet stock on the Nasdaq Stock Market, Nextel's equity
interest in Clearnet had a market value of approximately $82 million. Although
Nextel is permitted to transfer its interest in Clearnet to the Company, there
can be no assurance that Nextel will effect such transfer or, should such
transfer occur, that the market value of Nextel's equity interest in Clearnet on
the date of any such transfer will not be less than the market value of such
equity interest as of June 30, 1997.
    
 
CORPORATE GOVERNANCE
 
     The following is a description of the Company's contractual relationships
with its partners in the Operating Companies.
 
     Brazil. The Company owns 81% of the Class A voting stock of McCaw Brazil,
which entitles it to 90% of the voting rights. The Company, therefore, has the
right to make management and operating decisions of McCaw Brazil. The Telcom
Group owns 19% of the Class B voting stock, which entitles it to 10% of the
voting rights. The Telcom Group has the right to designate candidates
representing at least 10% of the directors of McCaw Brazil, but at least one
candidate so long as the Telcom Group owns at least 10% of McCaw Brazil. The
Telcom Group holds veto rights with respect to the following actions: (i)
amending the articles of incorporation or bylaws of McCaw Brazil; (ii) creating
any equity senior to the existing shares of McCaw Brazil or changing or
adversely affecting any provisions or rights of the existing shares of McCaw
Brazil; (iii) permitting or causing McCaw Brazil or any of its material
subsidiaries to issue voting securities with voting rights different from those
to which then-issued securities are entitled; (iv) entering into a merger, a
sale of substantially all of the assets, a dissolution, a liquidation or a
spinoff of McCaw Brazil or any of its material subsidiaries; (v) permitting
McCaw Brazil or any of its subsidiaries to enter into a material contract with
the Company or its affiliates other than on an arm's-length, fair-market-value
basis; or (vi) permitting McCaw Brazil or any of its affiliates to issue or
dispose of securities of the Company other than for cash at fair
 
                                       87
<PAGE>   90
 
market value. If the Telcom Group exercises its veto rights, McCaw Brazil has
the right to purchase (upon vote of a simple majority of its board of directors)
all of the Telcom Group's shares of McCaw Brazil then owned by them at their
appraised fair market value. The repurchase price can be paid in cash or in
shares of Nextel common stock or a combination thereof. McCaw Brazil has the
right to declare dividends without the approval of the Telcom Group.
 
     The Telcom Group has the right to forego making its pro rata share of any
capital calls that may arise until April 1999 without suffering any dilution of
its right to receive dividends and other cash or noncash distributions;
provided, however, the failure by the Telcom Group to ultimately make such
capital contributions (and interest thereon) by April 1999 will result in the
proportionate dilution of its economic interest in McCaw Brazil. The Telcom
Group has the right at any time between October 31, 2001 and November 1, 2003,
or at any time after a change of control of McCaw Brazil, to require McCaw
Brazil to redeem the Telcom Group's entire interest at its appraised fair market
value. The redemption price is payable in cash, or, at McCaw Brazil's election,
publicly-traded common stock of any entity owning 50% or more of McCaw Brazil or
a combination thereof. In the event that McCaw Brazil issues additional shares
of its common stock to such a third party and, as a result, the Telcom Group's
interest in McCaw Brazil is reduced to less than 17%, the Telcom Group has the
right to purchase additional shares in McCaw Brazil such that after the issuance
to a third party, the Telcom Group would own no more than 17% of the outstanding
common stock.
 
     The Company has a right of first refusal with respect to proposed transfers
by members of the Telcom Group of their respective interests in McCaw Brazil and
has the right to compel the Telcom Group to join in any proposed transfer by the
Company of its entire interest in McCaw Brazil. The Telcom Group has the right
to join in any proposed transfer by the Company of its entire interest in McCaw
Brazil.
 
     Argentina. As long as the Company holds at least a 30% interest in McCaw
Argentina and WVA holds at least a 40% interest in McCaw Argentina, the
six-member board of McCaw Argentina will be equally divided. If one party fails
to maintain such level of ownership (while the other maintains it), the party
failing to maintain its ownership will lose the right to designate one of its
three members of the board of directors. Failure to maintain at least a 10%
ownership interest will result in loss of all board seats held by such party.
 
     As long as WVA maintains at least a 40% ownership interest, McCaw Argentina
will be operated in accordance with a three-year business plan adopted by its
board of directors. As long as the Company owns at least 30% of McCaw Argentina,
the following actions will require the approval of two-thirds of the board of
directors: (i) appoint McCaw Argentina's chief executive officer, president and
senior executives in charge of technology, finance and marketing; (ii) amend or
adopt any three-year business plan; or (iii) issue equity securities
representing 5% or more of the shares of McCaw Argentina. The declaration of
dividends also requires the approval of WVA.
 
     As long as each of the Company and WVA own at least 10% of the outstanding
shares of McCaw Argentina the following actions will require the approval of
two-thirds of the directors: (i) creating any equity senior to the existing
shares of McCaw Argentina or changing or adversely affecting any provisions or
rights of the existing shares of McCaw Argentina; (ii) permitting or causing
McCaw Argentina or any of its material subsidiaries to issue voting securities
with voting rights different from those to which then-issued securities are
entitled; (iii) permitting McCaw Argentina or any of its subsidiaries to enter
into a material contract with the Company or its affiliates other than on an
arm's-length, fair-market-value basis; or (iv) permitting McCaw Argentina or any
of its affiliates to issue or dispose of securities of the company other than
for cash at fair market value. In addition, for as long as the Company and WVA
each own at least 10% of the outstanding shares of McCaw Argentina, the
following actions require approval of the holders of two-thirds of McCaw
Argentina's shares: (i) amending the organizational documents of McCaw
Argentina; and (ii) entering into a merger, a sale of substantially all of the
assets, a dissolution, a liquidation or a spinoff of McCaw Argentina or any of
its material subsidiaries.
 
     If (i) WVA exercises its veto power or (ii) at a time when the Company owns
less than 30% and WVA owns at least 40% of the outstanding shares of McCaw
Argentina, respectively, the Company exercises its veto power, McCaw Argentina
shall have the right, upon approval of a majority of the directors of McCaw
Argentina (excluding the directors nominated by the party that exercised its
veto), to repurchase the shares of
 
                                       88
<PAGE>   91
 
the party exercising its veto right at their appraised fair market value. The
repurchase price is payable, at McCaw Argentina's option, in cash, Nextel common
stock or in any combination thereof.
 
     The Company has a right of first refusal with respect to transactions by
WVA of its shares of McCaw Argentina and has the right to compel WVA to join in
any proposed transfer by the Company of its entire interest in McCaw Argentina.
WVA has the right to join in any proposed transfer by the Company of its entire
interest in McCaw Argentina.
 
     Mexico. In accordance with agreements with other principal shareholders of
Mobilcom, so long as the Company owns 27.5% of the outstanding voting stock of
Mobilcom, the Company has the right to designate a majority of Mobilcom's board
of directors. The Company, therefore, subject to the business plan adopted by
the Mobilcom shareholders, has control over Mobilcom's day-to-day operational
decisions, such as the selection of senior management, sales and marketing
decisions and acquisitions or disposition of assets (up to $20 million). Under
these same agreements, Grupo San Luis, so long as it owns at least 5% of
Mobilcom (15% of Mobilcom in the event that it has disposed of any of its
current shareholdings) has the right to designate two members of the Mobilcom
board of directors. The other board members are elected by a cumulative voting
process and currently are representatives of each of WVM and Associated SMR. The
Company also has the right to designate one of the two members of the Technology
Committee of the Mobilcom board of directors. The Technology Committee has sole
and exclusive authority to make all technology decisions relating to the
Company's digital mobile systems including technology decisions related to
vendor selection and build-out and system design. The other member of the
Technology Committee is a designee of WVM.
 
     Under the agreements relating to the governance of Mobilcom, so long as
Grupo San Luis owns at least 5% and the Company owns at least 20% of Mobilcom,
the following matters require a supermajority vote of the shareholders: (i)
amendments to Mobilcom's and its subsidiaries' charter; (ii) issuance of shares
with disproportionate voting rights; (iii) adoption of any stockholders rights
plan to disadvantage any shareholder on the basis of this size of its holding;
(iv) issuances of shares aggregating to more than 15% of the outstanding shares
at the commencement of any 36-month period, subject to certain exceptions; (v)
the establishment of an executive or special committee of the board of directors
other than the Technology Committee; (vi) acquisition, disposition, loan and
certain other transactions having a value in excess of $20 million; (vii)
adoption of and approval of any material deviation of business plans, marketing
plans, capital expenditure plan or operating budget; (viii) incurrence of
capital expenditures in excess of 125% of the capital expenditure budget
approved by shareholders; (ix) a decision to change the core business; and (x)
approval of any offer for subscription of treasury shares in respect of which
shareholders preemptive rights have been waived.
 
     In order to maintain its right to designate a majority of the board of
directors, to designate one of the two members of the Technology Committee and
to block certain significant actions of Mobilcom, the Company must invest a
minimum of approximately $76.8 million in Mobilcom by March 3, 1998. As of April
30, 1997, the Company had invested approximately $64.9 million in Mobilcom. The
Company may satisfy its remaining commitment by (i) making capital contributions
to Mobilcom, provided that such capital contributions are not part of the pro
rata capital contributions to Mobilcom in which the other principal shareholders
of Mobilcom participate; (ii) making a capital contribution to Mobilcom to be
used for the purchase of Radiocel; or (iii) exercising the Mobilcom Options.
 
     Pursuant to one of the Mobilcom Options, the Company has an option to
purchase up to 19.5% of the common stock of Mobilcom outstanding as of June 6,
1996, for an aggregate exercise price of $76.8 million. The other Mobilcom
option gives the Company the right to purchase up to an additional 9.98% of the
outstanding common stock of Mobilcom for an aggregate exercise price of $67.5
million.
 
     Beginning on October 24, 1997, pursuant to the Mobilcom Put the holders of
approximately 37% of the outstanding common stock of Mobilcom have the right for
two years to put the entire amount of their holdings to the Company at its
appraised fair market value for cash. The Mobilcom Put is exercisable if
Mobilcom takes any of the following corporate actions and the directors
designated to Mobilcom's board of directors by the holders of the Mobilcom Put
vote against such action: (i) a material amendment of the charter or bylaws;
(ii) issuance of voting securities with disproportionately larger voting rights
or a class vote; (iii) certain
 
                                       89
<PAGE>   92
 
issuance of shares in excess of 15% of the outstanding shares during a 36-month
period; (iv) making any investment, loaning any amount, or selling assets in
excess of $20 million; (v) the adoption of material deviations from any business
plan, operating budget or capital expenditure plan; and (vi) making capital
expenditures that would exceed 125% of the capital expenditure budget approved
by the shareholders. In addition, the Mobilcom Put is exercisable in the event
that the holders of the Mobilcom Put are no longer entitled to designate in the
aggregate at least two directors. The Mobilcom Put is automatically exercisable
on October 24, 1999 whether or not a Mobilcom Put Event occurs. Valuation of
Mobilcom for purposes of the Mobilcom Put will be based on an appraisal by an
investment bank, with the minimum appraisal for 100% of Mobilcom equal to $150
million. To the extent that such appraisal exceeds $250 million, 50% of such
excess will be included in the valuation. In connection with a June 7, 1996
capital call, Mobilcom shareholders purchased additional shares of Mobilcom
based on a $200 million valuation (which values the Mobilcom Put at
approximately $66 million). If the Mobilcom Put is not exercised by October 24,

     China. Under current Chinese law, foreign entities or individuals are
prohibited from participating directly in the ownership and operation of
telecommunications services. Because of this limitation, the Company's interest
in the Shanghai GSM System is held through its 60% equity interest in a Chinese
equity joint venture, Shanghai McCaw. Shanghai McCaw participates in the
Shanghai GSM System through a profit-sharing arrangement entered into originally
between SSTIC, its Chinese partner, and Unicom (the "Unicom Agreement"). SSTIC,
holds a 40% equity interest in Shanghai McCaw.
 
     Pursuant to the Unicom Agreement, Shanghai McCaw receives 42% of the net
revenues of the Shanghai GSM System. The Unicom Agreement is structured to
provide the financing for the construction of a system that can service 50,000
subscribers. As of December 31, 1996, the Shanghai GSM System had 28,000
subscribers. The Unicom Agreement expires on February 25, 2007.
 
     Pursuant to a joint venture agreement and other agreements entered into
between the Company and SSTIC (the "Shanghai McCaw Agreements"), the Company and
SSTIC have equal representation on the board of directors of Shanghai McCaw. In
addition, the Company has the right to appoint Shanghai McCaw's

general manager and chief engineer, subject to SSTIC's approval. Certain
significant corporate actions require unanimous approval of the board of
directors, including: (i) an amendment to the articles of association; (ii)
changes in the ratio of the partners' capital contribution; and (iii) the merger
or dissolution of Shanghai McCaw. Certain other matters require the approval of
at least six of eight members of the board of directors. Those matters include
the following: (i) allowing a third party to participate in the ownership of
McCaw Shanghai; (ii) changes in capitalization; (iii) borrowing money; (iv)
paying dividends; (v) approving operating and capital budgets; (vi) changing the
management structure; (vii) entering into transactions with affiliates; (viii)
the purchase and sale of capital equipment; and (ix) any action not in the
ordinary course of business of Shanghai McCaw. Neither party is permitted to
sell its interest in Shanghai McCaw without the consent of the other party.
 
     In addition to its capital contribution, the Company was responsible for
providing a $13.2 million loan facility to Shanghai McCaw to fund the Shanghai
GSM System. At December 31, 1996, the outstanding balance of this loan was $10.5
million. In the event of an overrun in the budget for the Shanghai GSM System,
the Company agreed to lend an additional $2.2 million to Shanghai McCaw.
 
     On March 29, 1997, Unicom and Shanghai McCaw entered into the Phase III
Unicom Agreement, which modifies certain arrangements under the Unicom
Agreement. Pursuant to the Phase III Unicom Agreement (i) Shanghai McCaw has
agreed to provide 60% of the funds required to expand the capacity of the
Shanghai GSM System to provide service for an additional 100,000 subscribers.
Shanghai McCaw's share of the funds is estimated to be equal to approximately
RMB 386.4 million (approximately US$46.4 million). Pursuant to the Phase III
Unicom Agreement (i) the 42% profit sharing arrangements under the Unicom
Agreement were retained for the period up to the date on which the 50,001st
subscriber (currently, there are approximately 30,000 subscribers) of the
Shanghai GSM System is activated (the "Phase III Commencement Date"); (ii)
following the Phase III Commencement Date the allocation of profit sharing
arrangement between the parties is revised to provide Unicom with a greater
percentage resulting in Shanghai McCaw receiving 40.2% of the profits of the
Shanghai GSM System; (iii) the Phase III Unicom Agreement expires 14 1/3 years
after the Phase III Commencement Date.

(3) The Company's common stock is not registered or publicly traded and
    therefore a public market price for the common stock is not available. Net
    realizable value of the SARs is based on a fair market value of $10 per
    share as of the date of grant. The base price per share is based on the
    Board of Directors' estimate of fair market value at the time of grant. The
    actual value, if any, an employee may realize will depend on the excess of
    fair market value of McCaw International common stock over the base price on
    the date the SAR is exercised. The dollar amounts under these columns are
    the result of calculations at the 5% and 10% rates set by the Commission
    and, therefore, are not intended to forecast future appreciation, if any, of
    the SARs.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     The Company's Board of Directors does not currently have a compensation
committee. The Company's Board of Directors is responsible for executive
compensation matters. During 1996, Mr. Grinstein served on the Company's Board
of Directors and as Chief Executive Officer and President of the Company.
 
BENEFIT PLANS
 
     Nextel Incentive Equity Plan.  All officers, key employees of and
consultants to Nextel and its subsidiaries, including McCaw International, are
eligible to participate in the Nextel Incentive Equity Plan (the "Incentive
Equity Plan"). The Compensation Committee of the Nextel Board (the "Nextel
Compensation Committee") may grant each eligible participant options entitling
the optionee to purchase shares of Nextel Class A Common Stock at a price equal
to or greater than market value on the date of grant, except that the option
price of an option that is granted in exchange for the surrender and
cancellation of an option to purchase shares of another corporation that has
been acquired by the Nextel or one of its subsidiaries ("Replacement Options")
or options granted to a consultant may be less than the market value on the date
of grant. Replacement Options and options granted to consultants are otherwise
subject to the same terms, conditions and discretion as other options granted
under the Incentive Equity Plan.
 
     The option price is payable at the time of exercise (i) in cash, (ii) by
the transfer to Nextel of nonforfeitable, nonrestricted shares of Nextel Class A
Common Stock that are already owned by the optionee and have a value at the time
of exercise equal to the option price, (iii) with any other legal consideration
the Nextel Compensation Committee may deem appropriate or (iv) by any
combination of the foregoing methods of payment. Any grant of options may
provide for deferred payment of the option price from the proceeds of sale
through a bank or broker on the date of exercise of some or all of the shares of
Nextel Class A Common Stock to which the exercise relates.
 
     No option may be exercised more than 10 years from the date of grant. Each
option must specify the vesting period and other terms for the exercise of such
option and may provide for the earlier exercise of the options in the event of a
change in control of Nextel or other similar transaction or event. Options
granted under the Incentive Equity Plan may be designated as "incentive stock
options" within the meaning of Section 422 of the Internal Revenue Code of 1986,
as amended (the "Code"), or may be designated as options that are not intended
to so qualify.
 
     The Nextel Compensation Committee may also grant eligible participants in
the Incentive Equity Plan Appreciation Rights, Restricted Shares, Deferred
Shares, Performance Shares or Performance Units (each as defined in the
Incentive Equity Plan). The Nextel Compensation Committee must specify at the
time of grant the vesting period and other terms of any such award.
 
     No option, appreciation right or other "derivative security" within the
meaning of Rule 16b-3 under the Exchange Act is transferable by a recipient
except by will or the laws of descent and distribution. Options and Appreciation
Rights may not be exercised during a recipient's lifetime except by the
recipient or, in the event of his or her incapacity, by his or her guardian or
legal representative acting in a fiduciary capacity on behalf of the recipient
under state law and court supervision. The Nextel Compensation Committee may
specify at the date of grant that all or any part of the shares of Nextel Class
A Common Stock that are to be issued or transferred by Nextel pursuant to the
Incentive Equity Plan shall be subject to further restrictions on transfer.
 
     The Incentive Equity Plan is administered by the Nextel Compensation
Committee, which consists of not less than three nonemployee directors who are
"disinterested persons" within the meaning of Rule 16b-3 under the Exchange Act.
The Nextel Compensation Committee may make grants to participants under any or a
combination of all of the various categories of awards that are authorized under
the Incentive Equity Plan and may provide for special terms for awards to
participants who either are foreign nationals or are employed by or provide
consulting services to Nextel or any of its subsidiaries outside of the United
States, as the Nextel Compensation Committee may consider necessary or
appropriate to accommodate differences in local law, tax policy or custom.
 
                                       96
<PAGE>   99
 
     The Incentive Equity Plan may be amended from time to time by the Nextel
Compensation Committee, but without further approval by the stockholders of
Nextel no such amendment may (i) increase the aggregate number of shares of
Nextel Class A Common Stock that may be issued or transferred and covered by
outstanding awards, or increase the aggregate number of Performance Units that
may be granted, thereunder or (ii) otherwise cause Rule 16b-3 under the Exchange
Act to cease to be applicable to the Incentive Equity Plan.
 
     Nextel Stock Purchase Plan.  All employees of Nextel and its subsidiaries,
including McCaw International, who are customarily employed for more than 20
hours per week are eligible to elect to be granted options under the Nextel
Stock Purchase Plan (the "Stock Purchase Plan"). Section 423 of the Code,
however, prohibits the granting of an option to any employee who would own stock
possessing five percent or more of the total combined voting power or value of
all classes of stock of Nextel or any of its subsidiaries following the granting
of the option. For purposes of the foregoing, shares of stock that are subject
to outstanding options or other vested or contingent rights to acquire the same
are deemed to be owned by the optionee.
 
     The option price per share upon exercise of an option granted under the
Stock Purchase Plan is an amount equal to 85 percent of the lesser of (i) the
fair market value of a share of Nextel Class A Common Stock on the date of grant
or (ii) the fair market value of a share of Nextel Class A Common Stock on the
date of exercise. For purposes of the Stock Purchase Plan, "fair market value"
means the closing price of the Nextel Class A Common Stock on the Nasdaq
National Market on the last trading date preceding the date of the grant or the
date of exercise, as the case may be.
 
     The option price is payable by the optionee on the date of exercise with
funds accumulated through payroll withholding over the term of the option or, at
the discretion of the Nextel Compensation Committee, with funds paid to Nextel
by the optionee in a lump sum on or before the date of exercise. An optionee may
elect to have not less than one percent and not more than ten percent of his or
her "basic compensation," which includes base salary and any commissions paid
pursuant to an ongoing sales incentive compensation program but does not include
cash bonuses or any form of noncash compensation, withheld from payroll and
applied to the purchase of Nextel Class A Common Stock upon the exercise of
options granted under the Stock Purchase Plan.
 
     The maximum number of shares of Nextel Common Stock that an optionee may
purchase upon exercise of an option granted under the Stock Purchase Plan is
equal to ten percent of his or her basic compensation divided by an amount equal
to 85 percent of the lesser of (i) the fair market value of a share of Nextel
Class A Common Stock on the date of grant or (ii) the fair market value of a
share of Nextel Class A Common Stock on the date of exercise, subject to further
limitations imposed by Section 423 of the Code. Section 423 of the Code provides
that, among other things, the right of an optionee to purchase stock under all
"employee stock purchase plans" (as defined in Section 423 of the Code) of a
corporation and its subsidiaries may not accrue at a rate that exceeds $25,000
of fair market value (determined at the time of grant) for each calendar year in
which the option is outstanding at any time.
 
     Options granted under the Stock Purchase Plan may have terms of not less
than three months and not more than one year, as determined by the Nextel
Compensation Committee in its sole discretion, provided that all options granted
pursuant to any particular offering under the Stock Purchase Plan must have the
same term for all optionees. The first day of the relevant term of an option
granted under the Stock Purchase Plan is the grant date with respect to such
option, and the date of exercise of an option granted under the Stock Purchase
Plan is the last day of its term. No option granted under the Stock Purchase
Plan may be transferred by the optionee.
 
     The Stock Purchase Plan is administered by the Nextel Compensation
Committee, which may establish such policies or procedures and adopt such rules
for the operation and administration of the Stock Purchase Plan as it deems
appropriate. Nextel may engage the services of a professional plan administrator
on such terms and conditions as the Nextel Compensation Committee deems
appropriate for the purposes of establishing and maintaining custodial accounts
and holding shares of Nextel Common Stock acquired by employees upon the
exercise of options granted under the Stock Purchase Plan and otherwise
operating the
 
                                       97
<PAGE>   100
 
Stock Purchase Plan. The Nextel Compensation Committee also has the authority to
promulgate terms and conditions (to the extent not inconsistent with the terms
and conditions prescribed in the Stock Purchase Plan) applicable to grants made
under the Stock Purchase Plan, including, without limitation, holding periods
for shares of Nextel Class A Common Stock purchased upon the exercise of an
option granted under the Stock Purchase Plan beyond those required to obtain
favorable tax treatment under Section 423 of the Code and sanctions for failing
to comply with the terms and conditions applicable to particular grants (in
addition to those otherwise imposed by law or the terms of the Stock Purchase
Plan).
 
     The Stock Purchase Plan will terminate the tenth anniversary of its
adoption by the Nextel Board, unless sooner terminated by the Nextel Board, and
no options will thereafter be granted thereunder. The Stock Purchase Plan may be
amended from time to time by the Board of Directors, but without further
approval by the stockholders of Nextel, no such amendment may (i) increase the
aggregate number of shares of Nextel Class A Common Stock covered by the Stock
Purchase Plan, except for adjustments to reflect the effects of stock dividends,
stock splits, combinations of shares or other changes in the capital structure
of Nextel, (ii) permit the granting of options under the Stock Purchase Plan to
persons other than employees of Nextel and its subsidiaries who are customarily
employed for more than 20 hours per week, (iii) cause options granted under the
Stock Purchase Plan to fail to satisfy any of the conditions of Section 423 of
the Code or (iv) cause Rule 16b-3 under Section 16(b) of the Exchange Act (or
any successor rule to the same effect) to cease to be applicable to the Stock
Purchase Plan.
 
   
     McCaw International Stock Appreciation Rights Plan.  The Company has
granted to selected employees and agents SARs in accordance with the Company's
SAR Plan. The surrender of a SAR, in accordance with the terms of the SAR Plan,
entitles the holder thereof to receive the increase in fair market value of one
share of the Company's Common Stock between the date of its grant and the date
of surrender. The SAR Plan contains provisions establishing how the fair market
value of the Company's Common Stock will be determined. As of December 31, 1996,
1,235,000 SARs had been granted pursuant to the SAR Plan. SARs vest on a monthly
basis over a four-year period and once vested may be surrendered by a holder in
installments of 20% per year; provided, however, that no more than a maximum of
$5 million in the aggregate will be paid out in any one year to all SAR holders.
Certain of the senior officers of the Company have been granted rights whereby
their SARs will automatically vest upon a change of control of the Company (as
defined in the SAR Plan).
    
 
   
     On June 23, 1997, the board of the directors of the Company adopted,
subject to the approval of Nextel, the Company's sole shareholder, the Company's
1997 Stock Option Plan and approved a plan to terminate the SAR Plan. Each
holder of SARs granted previously under the SAR Plan has been given the right to
exchange his or her SARs for options to be granted under the 1997 Stock Option
Plan. The Company has agreed to grant additional stock options to SAR holders
who exchange their SARs for stock options as an inducement to such SAR holders.
The Company expects holders representing a substantial majority of the
outstanding SARs, including all of the members of the Company's senior
management team, to exchange their SARs for options granted under the 1997 Stock
Option Plan.
    
 
   
     McCaw International Stock Option Plan.  All employees, officers, directors,
agents, independent contractors of and advisors and consultants to McCaw
International, its subsidiaries and affiliates are eligible to participate in
the 1997 Stock Option Plan. The McCaw International Board of Directors or a
committee designated thereby (the "Plan Administrator") may grant each eligible
participant options entitling the optionee to purchase shares of McCaw
International common stock at a price equal to at least 100% of the market value
on the date of grant.
    
 
   
     The option price is payable at the time of exercise (i) in cash, (ii) by
the transfer to the Company of shares of McCaw International common stock
already owned by the optionee for at least six months and having a value at the
time of exercise equal to the aggregate option exercise price, (iii) with any
other legal consideration the Plan Administrator may deem appropriate or (iv) at
the discretion of the Plan Administrator, by any combination of the foregoing
methods of payment.
    
 
   
     No option may be exercised more than 10 years from the date of grant. Each
option must specify the vesting period and other terms for the exercise of such
option. Options granted under the 1997 Stock Option
    
 
                                       98
<PAGE>   101
 
   
Plan vest over four years but may not be exercised prior to two years following
the date of grant. Options granted under the 1997 Stock Option Plan may be
designated as "incentive stock options" within the meaning of Section 422 of the
Internal Revenue Code of 1986, as amended (the "Code"), or may be designated as
options that are not intended to so qualify.
    
 
   
     Each optionee has the right to sell any shares acquired pursuant to the
exercise of an option to the Company or an affiliate of the Company after such
shares have been held for at least six months. The sale price for such shares is
the fair market value as of the date of sale. Additionally, the Company has a
right of first refusal on any proposed sale of shares acquired pursuant to the
exercise of an option. Options are not transferable by a recipient except by
will or the laws of descent and distribution. Options may not be exercised
during a recipient's lifetime except by the recipient or, in the event of his or
her incapacity, by his or her guardian or legal representative acting in a
fiduciary capacity on behalf of the recipient under state law and court
supervision. The Plan Administrator may specify at the date of grant that all or
any part of the shares of the McCaw International common stock are to be issued
pursuant to the 1997 Stock Option Plan shall be subject to further restrictions
on transfer.
    
 
   
     The Plan Administrator may provide for special terms for awards to
participants who either are foreign nationals or are employed by or provide
consulting services to the Company or any of its subsidiaries outside of the
United States, as the Plan Administrator may consider necessary or appropriate
to accommodate differences in local law, tax policy or custom.
    
 
   
     The 1997 Stock Option Plan may be amended from time to time by the Board of
Directors of McCaw International; provided, however, to the extent required for
compliance with any applicable law or regulation, shareholder approval will be
required for any amendment that will (i) increase the aggregate number of shares
of McCaw International common stock as to which options may be granted under the
plan; (ii) modify the class of persons eligible to receive options; or (iii)
otherwise require shareholder approval under any applicable law or regulations.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
TAX SHARING AGREEMENT
 
     The Tax Sharing Agreement effective as of January 1, 1997, between Nextel
and the Company (the "Tax Sharing Agreement") provides that the Company must pay
Nextel its federal income tax liability computed as if the Company had filed a
separate federal income tax return. Such computation would take into account any
carryovers and carrybacks of losses and credits that would be allowed if the
Company had filed a separate federal income tax return except that, in making
such computation for any taxable year, such liability will be determined at the
highest corporate tax rate, and without an exemption for purposes of calculating
the alternative minimum tax and the environmental tax. The Tax Sharing Agreement
further provides that the Company may be included in any consolidated, combined,
or unitary state or local income or franchise tax return or report, and the
Company's liability with respect to such taxes will be computed in a manner
similar to and consistent with the calculation of the Company's federal income
tax liability.
 
     Furthermore, the Tax Sharing Agreement provides that Nextel is entitled to
utilize on behalf of the consolidated group all of the tax attributes and other
items of income, gain, loss, deduction, expense, credit and similar treatments
of the Company arising in the current taxable year or another taxable year or
years and which properly may be carried back or carried forward to such taxable
year. The Company is not entitled to receive any compensation by reason of
Nextel's utilization of such attributes or items on behalf of the group in
determining for any taxable year or years the consolidated taxable income and
consolidated tax liability for such taxable year or years.
 
     Nextel will not be required to compensate the Company for the benefit of
loss or credit carryback from the Company's separate filing to the consolidated
group should the Company leave the Nextel consolidated group.
 
     Under the U.S. consolidated income tax rules, the Company and each other
member of the U.S. consolidated tax group of which it is a member will be
jointly and severally liable for the U.S. tax liabilities of each other member
of such group.
 
OVERHEAD SERVICES AGREEMENT
 
     Pursuant to an Overhead Services Agreement effective as of the Closing Date
between the Company and Nextel (the "Services Agreement"), Nextel has agreed to
provide to the Company certain services, including those relating to accounts
payable, cash management, payroll, human resources, finance reporting and audit
and legal, engineering and technical and marketing and sales assistance. The fee
for services provided pursuant to the Services Agreement is the actual cost
incurred by Nextel, which is billed monthly and payable in 45 days. Pursuant to
the Services Agreement, Nextel has agreed to apportion the aggregate cost
incurred by it to provide such services to the Company and Nextel's other
subsidiaries on the basis that Nextel determines in good faith, from time to
time, represents the relative portion of such services provided by Nextel and
used by each such subsidiary, including the Company, for the relevant period.
The Company has the right to review Nextel's determination and to discuss with
Nextel adjustments that the Company considers appropriate in light of the
services provided to the Company. Nextel's good faith determination after such
consultation is final and binding. The Services Agreement has a ten-year term
and, with the consent of Nextel, the Company may elect to discontinue a
particular service or services provided by Nextel and/or obtain any service from
an independent third party.
 
     Pursuant to the Services Agreement the Company has agreed that the legal
counsel employed by Nextel as parttime or full-time employees will provide legal
services to Nextel as well as to other subsidiaries of Nextel and potentially to
other entities in which Nextel holds an ownership interest. The Company has
agreed that such legal counsel may represent the Company as well as Nextel or
any such other subsidiary or any other entity.
 
                                       100
<PAGE>   103
 
NONCOMPETE AGREEMENT
 
     The Company and Nextel entered into the Non-Compete Agreement effective as
of the Closing Date pursuant to which Nextel has agreed that neither Nextel nor
any Affiliate (as defined in the agreement) controlled by Nextel will in the
future participate in the ownership or operation of two-way terrestrial-based
mobile wireless communications systems anywhere other than in the United States
and Canada (for so long as Nextel owns an equity interest in Clearnet) unless
such opportunities have first been presented to the Company. Such restriction
does not apply to, among other things, any commercial relationship with any
Wireless Entity (including channel or frequency sharing, roaming, purchase or
sale of goods or services, licensing of intellectual property or other
intangible rights or similar business related arrangement) that does not involve
the directing or participating in the management of such Wireless Entity. The
Company has agreed that, without the consent of Nextel, neither it, its
Restricted Affiliates nor any of its Unrestricted Affiliates (each as defined in
the "Description of the Notes") will participate in the ownership or management
of any wireless communications service business in the United States or Canada
other than with respect to its interest in Clearnet. Such restrictions terminate
upon the earliest to occur of (i) April 15, 2007 and (ii) the date on which a
Change of Control (as defined in the "Description of the Notes") occurs.
 
     If Nextel gives the Company an Initial Notice of a Future Wireless
Opportunity, the Company will have 60 days to notify Nextel that it intends to
pursue such opportunity, and how it intends to finance its participation. The
Company must have secured a financing commitment within 90 days of the date of
the Initial Notice and the Future Wireless Opportunity must be consummated
within nine months of the date of the Initial Notice. In the event the Company
fails to respond to Nextel within the 60 and 90 day time frames or fails to
consummate the transaction within the nine-month period, Nextel will be free to
pursue the Future Wireless Opportunity.
 
     Nextel and the Company have agreed not to amend the Non-Compete Agreement
if such amendment is material and adverse to the holders of the Notes or the
Warrants and to provide such holders with written notice 30 days prior to any
amendment.
 
MOTOROLA RELATIONSHIPS
 
     Motorola, a significant shareholder of Nextel, provides equipment and
vendor financing to the Operating Companies. For a description of the Motorola
Financing, see "Management's Discussion and Analysis of Financial Condition and
Results of Operations."
 
     Nextel and the Company have entered into an agreement relating to the
Motorola Financing pursuant to which Nextel has agreed to make at least $95
million of the $400 million of vendor financing available to the Company. Nextel
is not obligated to make any additional amounts available to the Company under
the Motorola Financing. However, based on discussions with Nextel the Company
believes that it will be able to obtain sufficient funding under the Motorola
Financing to meet its business plan.

                       DESCRIPTION OF THE EXCHANGE NOTES
 
     The Private Notes were, and the Exchange Notes will be, issued under the
Indenture, dated as of March 6, 1997, between the Company, as issuer, and The
Bank of New York, as Trustee. A copy of the Indenture has been filed as an
Exhibit to the Registration Statement of which this Prospectus is a part. The
following summary of certain provisions of the Indenture does not purport to be
complete and is subject to, and is qualified in its entirety by reference to,
all the provisions of the Indenture, including the definitions of certain terms
therein and those terms made a part thereof by reference to the Trust Indenture
Act of 1939, as amended. Whenever particular defined terms of the Indenture not
otherwise defined herein are referred to, such defined terms are incorporated
herein by reference. For definitions of certain capitalized terms used in the
following summary, see "-- Certain Definitions."
 
GENERAL
 
     The Exchange Notes will be unsecured unsubordinated obligations of the
Company and will mature on April 15, 2007. Although for federal income tax
purposes a significant amount of original issue discount, taxable as ordinary
income, will be recognized by a Holder as such discount accrues from the issue
date of the Exchange Notes, no interest will be payable on the Exchange Notes
prior to October 15, 2002. From and after April 15, 2002, interest on the
Exchange Notes will accrue at the rate shown on the front cover of this
Prospectus from April 15, 2002 or from the most recent interest payment date to
which interest has been paid or provided for, payable semiannually (to Holders
of record at the close of business on the April 1 or October 1 immediately
preceding the interest payment date) on April 15 and October 15 of each year,
commencing October 15, 2002. Interest will be computed on the basis of a 360-day
year of twelve 30-day months.
 
     Principal of, premium, if any, and interest on the Exchange Notes will be
payable, and the Exchange Notes may be exchanged or transferred, at the office
or agency of the Company in the Borough of Manhattan, the City of New York
(which initially will be the corporate trust office of the Trustee at 101
Barclay Street, 21 West, New York, New York 10286); provided, that, at the
option of the Company, payment of interest may be made by check mailed to the
address of the Holders as such address appears in the Security Register.
 
     The Company may, subject to the covenants described below under "Covenants"
and applicable law, issue additional Notes under the Indenture. The Exchange
Notes offered hereby and any additional Notes subsequently issued would be
treated as a single class for purposes of the Indenture.
 
BOOK-ENTRY; DELIVERY AND FORM
 
     Exchange Notes issued in exchange for the Private Notes currently
represented by one or more fully registered global notes will be represented by
one or more fully registered global notes (collectively, the "Global Note"), and
will be deposited upon issuance with The Depository Trust Company (the
"Depository") or an agent of the Depository and registered in the name of the
Depository or a nominee of the Depository (the "Global Note Registered Owner").
Except as set forth below, the Global Note may be transferred, in whole and not
in part, only to another nominee of the Depository or to a successor of the
Depository or its nominee.
 
     Exchange Notes issued in exchange for other Private Notes will be issued in
registered, certificated form without interest coupons.
 
     The Depository has advised the Company that the Depository is a
limited-purpose trust company created to hold securities for its participating
organizations (collectively, the "Participants") and to facilitate the clearance
and settlement of transactions in those securities between Participants through
electronic book-entry changes in the accounts of its Participants. The
Participants include securities brokers and dealers, banks, trust companies,
clearing corporations and certain other organizations. Access to the
Depository's system is also available to other entities such as banks, brokers,
dealers and trust companies that clear through or maintain a custodial
relationship with a Participant, either directly or indirectly (collectively,
the "Indirect Participants"). Persons who are not Participants or Indirect
Participants may beneficially own securities held by or
 
                                       102
<PAGE>   105
 
on behalf of the Depository only through the Participants or the Indirect
Participants. The ownership interests and transfer of ownership interests of
such persons held by or on behalf of the Depository are recorded on the records
of the Participants and Indirect Participants.
 
     The Depositary has also advised the Company that pursuant to procedures
established by it, (i) upon deposit of the Global Note, the Depository will
credit the accounts of its Participants with portions of the principal amount of
the Global Note representing the Exchange Notes issued in exchange for the
Private Notes that each such Participant has instructed the Depository to
surrender for exchange and (ii) ownership of such interests in the Global Note
will be shown on, and the transfer of ownership thereof will be effected only
through, records maintained by the Depository (with respect to the Participants)
or by the Participants and the Indirect Participants (with respect to other
owners of beneficial interests in the Global Note).
 
     Under the terms of the Indenture, the Company and the Trustee will treat
the persons in whose names the Exchange Notes, including the Global Note, are
registered as the owners thereof for the purpose of receiving payments in
respect of the principal of and premium, if any, and interest on any Exchange
Notes and for any and all other purposes whatsoever. Payments on any Exchange
Notes registered in the name of the Global Note Registered Owner will be payable
by the Trustee to the Global Note Registered Owner in its capacity as the
registered holder under the Indenture. Consequently, neither the Company, the
Trustee nor any agent of the Company or the Trustee has or will have any
responsibility or liability for (i) any aspect of the Depository's records or
the records of any Participant or Indirect Participant relating to or payments
made on account of beneficial ownership interests in the Global Note, or for
maintaining, supervising or reviewing any of the Depository's records or records
of any Participant or Indirect Participant relating to the beneficial ownership
interests in the Global Note or (ii) any other matter relating to the actions
and practices of the Depository or any of its Participants or Indirect
Participants. The Depository has advised the Company that its current practice,
upon receipt of any payment in respect of securities such as the Exchange Notes
(including principal and interest), is to credit the accounts of the relevant
Participants with the payment on the payment date, in amounts proportionate to
their respective holdings in principal amount of beneficial interests in the
relevant security as shown on the records of the Depository unless the
Depository has reason to believe it will not receive payment on such payment
date. Payments by the Participants and the Indirect Participants to the
beneficial owners of Exchange Notes will be governed by standing instructions
and customary practices and will be the responsibility of the Participants or
the Indirect Participants and will not be the responsibility of the Depository,
the Trustee or the Company. Neither the Company nor the Trustee will be liable
for any delay by the Depository or any of its Participants or Indirect
Participants in identifying the beneficial owners of the Exchange Notes, and the
Company and the Trustee may conclusively rely on and will be protected in
relying on instructions from the Global Note Registered Owner for all purposes.
 
OPTIONAL REDEMPTION
 
     The Exchange Notes will be redeemable, at the Company's option, in whole or
in part, at any time or from time to time, on or after April 15, 2002 and prior
to maturity, upon not less than 30 nor more than 60 days' prior notice mailed by
first class mail to each Holder's last address as it appears in the Security
Register, at the following Redemption Prices (expressed in percentages of
principal amount at maturity), plus accrued and unpaid interest, if any, to the
Redemption Date (subject to the right of Holders of record on the relevant
Regular Record Date that is on or prior to the Redemption Date to receive
interest due on an Interest Payment Date), if redeemed during the 12-month
period commencing April 15, of the years set forth below:

</TABLE>
 
     In addition, at any time prior to April 15, 2000, the Company may redeem up
to 35% of the principal amount at maturity of the Exchange Notes with the Net
Cash Proceeds of one or more sales by the Company of its Capital Stock (other
than Redeemable Stock), at any time as a whole or from time to time in part, at
a

<PAGE>   106
 
Redemption Price (expressed as a percentage of Accreted Value on the Redemption
Date) of 113%, plus accrued and unpaid interest, if any, to the Redemption Date
(subject to the right of Holders of record on the relevant Regular Record Date
that is on or prior to the Redemption Date to receive interest due on an
Interest Payment Date); provided that at least $618.5 million aggregate
principal amount at maturity of Exchange Notes remains outstanding after each
such redemption.
 
     In the case of any partial redemption, selection of the Exchange Notes for
redemption will be made by the Trustee in compliance with the requirements of
the principal national securities exchange, if any, on which the Exchange Notes
are listed or, if the Exchange Notes are not listed on a national securities
exchange by lot or by such other method as the Trustee in its sole discretion
shall deem to be fair and appropriate; provided that no Note of $1,000 in
principal amount at maturity or less shall be redeemed in part. If any Note is
to be redeemed in part only, the notice of redemption relating to such Note
shall state the portion of the principal amount at maturity thereof to be
redeemed. A new Note in principal amount equal to the unredeemed portion thereof
will be issued in the name of the Holder thereof upon cancellation of the
original Note.
 
REGISTRATION RIGHTS
 
     Pursuant to the Registration Rights Agreement, the Company agreed, for the
benefit of the Holders, that it would use its best efforts, at its cost, to
consummate this Exchange Offer. In satisfaction of this obligation, the Company
is hereby offering the Exchange Notes in return for surrender of the Private
Notes. It is intended by the Company that the Exchange Offer will satisfy these
registration rights, which will terminate upon the consummation of the Exchange
Offer. For each Private Note surrendered to the Company pursuant to the Exchange
Offer, the Holder will receive an Exchange Note of equal principal amount at
maturity. The Accreted Value of each Exchange Note shall be identical to, and
shall be determined in the same manner as, the Accreted Value of the Private
Notes so surrendered and exchanged therefor. Interest on each Exchange Note
shall be calculated and paid in the same manner as interest on the Private Notes
so surrendered and exchanged therefor.
 
RANKING
 
     The indebtedness evidenced by the Exchange Notes will rank pari passu in
right of payment with all existing and future unsubordinated unsecured
indebtedness of the Company and senior in right of payment to all existing and
future indebtedness of the Company that by its terms is subordinated to the
Exchange Notes. After giving pro forma effect to the Transactions and the
Initial Offering, as of December 31, 1996, the Company would have had no
indebtedness outstanding other than the Exchange Notes. All existing and future
liabilities (including trade payables) of the Company's Restricted Group Members
will be effectively senior to the Exchange Notes. As of December 31, 1996, after
giving effect to the Transactions, the Company's Restricted Group Members would
have had approximately $79.7 million of liabilities, including $25 million of
indebtedness.

     The Indenture contains, among others, the following covenants.
 
  Limitation on Indebtedness
 
     (a) The Company will not, and will not permit any Restricted Group Member
to, Incur any Indebtedness (other than the Exchange Notes and Indebtedness
existing on the Closing Date); provided that the Company may Incur Indebtedness,
and any Restricted Group Member may Incur Acquired Indebtedness, if, after
giving effect to the Incurrence of such Indebtedness and the receipt and
application of the proceeds therefrom, the Consolidated Leverage Ratio would be
less than 9 to 1, for Indebtedness Incurred on or prior to December 31, 1999, or
7 to 1, for Indebtedness Incurred thereafter.
 
     Notwithstanding the foregoing, the Company and any Restricted Group Member
(except as specified below) may Incur each and all of the following: (i)

provided under the "Limitation on Asset Sales" covenant described below; (ii)
Indebtedness (A) to the Company evidenced by an unsubordinated promissory note
or (B) to any Restricted Group Member; provided that any event which results in
any such Restricted Group Member ceasing to be a Restricted Group Member or any
subsequent transfer of such Indebtedness (other than to the Company or another
Restricted Group Member) shall be deemed, in each case, to constitute an
Incurrence of such Indebtedness not permitted by this clause (ii); (iii)
Indebtedness of the Company or any Restricted Group Member issued in exchange
for, or the net proceeds of which are used to refinance or refund, then
outstanding Indebtedness of the same Person (other than Indebtedness Incurred
under clause (i), (ii), (iv) or (vi) of this paragraph) or any refinancings
thereof in an amount not to exceed the amount so refinanced or refunded (plus

proceeds of which are used to refinance or refund the Exchange Notes or
Indebtedness that is pari passu with, or subordinated in right of payment to,
the Exchange Notes shall only be permitted under this clause (iii) if (A) in
case the Exchange Notes are refinanced in part or the Indebtedness to be
refinanced is pari passu with the Exchange Notes, such new Indebtedness, by its
terms or by the terms of any agreement or instrument pursuant to which such new
Indebtedness is outstanding, is expressly made pari passu with, or subordinate
in right of payment to, the
 
                                       116
<PAGE>   119
 
remaining Exchange Notes, (B) in case the Indebtedness to be refinanced is
subordinated in right of payment to the Exchange Notes, such new Indebtedness,
by its terms or by the terms of any agreement or instrument pursuant to which
such new Indebtedness is issued or remains outstanding, is expressly made
subordinate in right of payment to the Exchange Notes at least to the extent
that the Indebtedness to be refinanced is subordinated to the Exchange Notes and
(C) such new Indebtedness, determined as of the date of Incurrence of such new
Indebtedness, does not mature prior to the Stated Maturity of the Indebtedness
to be refinanced or refunded, and the Average Life of such new Indebtedness is
at least equal to the remaining Average Life of the Indebtedness to be
refinanced or refunded; (iv) Indebtedness (A) in respect of performance, surety
or appeal bonds provided in the ordinary course of business, (B) under Currency
Agreements and Interest Rate Agreements; provided that such agreements (a) are
designed solely to protect the Company or its Restricted Group Members against
fluctuations in foreign currency exchange rates or interest rates and (b) do not
increase the Indebtedness of the obligor outstanding at any time other than as a
result of fluctuations in foreign currency exchange rates or interest rates or
by reason of fees, indemnities and compensation payable thereunder; and (C)
arising from agreements providing for indemnification, adjustment of purchase
price or similar obligations, or from Guarantees or letters of credit, surety
bonds or performance bonds securing any obligations of the Company or any
Restricted Group Member pursuant to such agreements, in any case Incurred in
connection with the disposition of any business, assets or Restricted Group
Member (other than Guarantees of Indebtedness Incurred by any Person acquiring
all or any portion of such business, assets or Restricted Group Member for the
purpose of financing such acquisition), in a principal amount not to exceed the
gross proceeds actually received by the Company or any Restricted Group Member
in connection with such disposition; (v) Indebtedness of the Company, to the
extent the net proceeds thereof are promptly (A) used to purchase Exchange Notes
tendered in an Offer to Purchase made as a result of a Change in Control or (B)
deposited to defease the Exchange Notes as described below under "Defeasance";
(vi) Guarantees of the Exchange Notes and Guarantees of Indebtedness of the
Company by any Restricted Group Member provided the Guarantee of such
Indebtedness is permitted by and made in accordance with the "Limitation on

its Capital Stock (other than Redeemable Stock) to a Person that is not a
Subsidiary of the Company or a Restricted Affiliate, to the extent such Net Cash
Proceeds have not been used pursuant to clause (C)(2) of the first paragraph of
the "Limitation on Restricted Payments" covenant described below to make a
Restricted Payment and (y) 80% of the fair market value of property other than
cash received by the Company after the Closing Date from contributions of

Stock) to a Person that is not a Subsidiary of the Company or a Restricted
Affiliate.
 
     (b) Notwithstanding any other provision of this "Limitation on
Indebtedness" covenant, the maximum amount of Indebtedness that the Company or a
Restricted Group Member may Incur pursuant to this "Limitation on Indebtedness"
covenant shall not be deemed to be exceeded, with respect to any outstanding
Indebtedness due solely to the result of fluctuations in the exchange rates of
currencies.
 
     (c) For purposes of determining any particular amount of Indebtedness under
this "Limitation on Indebtedness" covenant, (1) Indebtedness Incurred under the

criteria of more than one of the types of Indebtedness described in the above
clauses (other than Indebtedness referred to in clause (1) of the preceding
sentence), the Company, in its sole discretion, shall
 
                                       117

or restrictions that are then in effect and that are being extended, refinanced,
renewed or replaced; (ii) existing under or by reason of applicable law; (iii)
existing with respect to any Person or the property or assets of such Person
acquired by the Company or any Restricted Group Member, existing at the time of

and the Company determines that any such encumbrance or restriction will not
materially affect the Company's ability to make principal or interest payments
on the Exchange Notes; (vii) contained in any stockholders or similar agreement,
so long as such encumbrance or restriction is not materially more
disadvantageous to the Holders of the Exchange Notes than the encumbrances and
restrictions contained in comparable agreements entered into in the past by the

entered into after the Closing Date, so long as such encumbrance or restriction
is not materially more disadvantageous to the Holders of the Exchange Notes than

shares or sales to foreign nationals of shares of Capital Stock of a foreign

the "Limitation on Indebtedness" covenant or (II) pursuant to clause (vii) of
the second paragraph of the "Limitation on Indebtedness" covenant. If the
Guaranteed Indebtedness is (A) pari passu with the Exchange Notes, then the
Guarantee of such Guaranteed Indebtedness shall be pari passu with, or
subordinated to, the Subsidiary Guarantee or (B) subordinated to the Exchange
Notes, then the Guarantee of such Guaranteed Indebtedness shall be subordinated
to the Subsidiary Guarantee at least to the extent that the Guaranteed
Indebtedness is subordinated to the Exchange Notes.

Affiliate.

properties of any character, or any shares of Capital Stock or Indebtedness of
any Restricted Group Member, without making effective provision for all of the
Exchange Notes and all other amounts due under the Indenture to be directly
secured equally and ratably with (or, if the obligation or liability to be
secured by such Lien is subordinated in right of payment to the Exchange Notes,
prior to) the obligation or liability secured by such Lien.

Closing Date; (ii) Liens granted after the Closing Date on any assets or Capital

Restricted Group Member sells or transfers such assets or properties and then or
thereafter leases such assets or properties or any part thereof or any other
assets or properties which the Company or such Restricted Group Member, as the
case may be, intends to use for substantially the same purpose or purposes as
the assets or properties sold or transferred.
 
     The foregoing restriction does not apply to any sale-leaseback transaction
if (i) the lease is for a period, including renewal rights, of not in excess of
three years; (ii) the lease secures or relates to industrial revenue or
pollution control bonds; (iii) the transaction is solely between the Company and
any Wholly Owned Restricted Subsidiary of the Company or solely between Wholly
Owned Restricted Subsidiaries of the Company; or (iv) the Company or such
Restricted Group Member, within twelve months after the sale or transfer of any
assets or properties is completed, applies an amount not less than the net
proceeds received from such sale in accordance with clause (A) or (B) of the
first paragraph of the "Limitation on Asset Sales" covenant described below.
 
  Limitation on Asset Sales
 
     The Company will not, and will not permit any Restricted Group Member to,
consummate any Asset Sale, unless (i) the consideration received by the Company
or such Restricted Group Member is at least equal to the fair market value of
the assets sold or disposed of and (ii) at least 75% of the consideration
received consists of cash or Temporary Cash Investments or the assumption of
Indebtedness of the Company or any Restricted Group Member relating to such
assets, provided that the Company or such Restricted Group Member is irrevocably
released and discharged from such Indebtedness. In the event and to the extent
that the Net Cash Proceeds received by the Company or any Restricted Group
Member from one or more Asset Sales occurring on or after the Closing Date in
any period of 12 consecutive months exceed $5 million, then the Company shall or
shall cause the relevant Restricted Group Member to (i) within twelve months
after the
 
                                       122
<PAGE>   125
 
date Net Cash Proceeds so received exceed $5 million (A) apply an amount equal
to such excess Net Cash Proceeds to permanently repay unsubordinated
Indebtedness of the Company or any Restricted Group Member providing a
Subsidiary Guarantee pursuant to the "Limitation on Issuances of Guarantees by
Restricted Group Members" covenant described above or Indebtedness of any other
Restricted Group Member, in each case owing to a Person other than the Company
or any Restricted Group Member, provided that in the event Indebtedness of a
Restricted Group Member is repaid, only the Company's pro rata portion
(determined as provided in the definition of "Indebtedness") of such repaid
Indebtedness shall be deemed to have been repaid in accordance with this clause
(A), or (B) invest an equal amount, or the amount not so applied pursuant to
clause (A) (or enter into a definitive agreement committing to so invest within
twelve months after the date of such agreement), in property or assets (other
than current assets) of a nature or type or that are used in a business (or in a
company having property and assets of a nature or type, or engaged in a
business) similar or related to the nature or type of the property and assets
of, or the business of, the Company and its Restricted Group Members existing on
the date of such investment and (ii) apply (no later than the end of the
twelve-month period referred to in clause (i)) such excess Net Cash Proceeds (to
the extent not applied pursuant to clause (i)) as provided in the last paragraph
of this "Limitation on Asset Sales" covenant. The amount of such excess Net Cash
Proceeds required to be applied (or to be committed to be applied) during such
twelve-month period as set forth in clause (i) of the preceding sentence and not
applied as so required by the end of such period shall constitute "Excess
Proceeds."
 
     Notwithstanding the foregoing, to the extent that any or all of the Net
Cash Proceeds of any Asset Sale of assets based outside the United States are
prohibited or delayed by applicable local law from being repatriated to the
United States and such Net Cash Proceeds are not actually applied in accordance
with the foregoing paragraphs, the Company shall not be required to apply the
portion of such Net Cash Proceeds so affected but may permit the applicable
Restricted Group Members to retain such portion of the Net Cash Proceeds so
long, but only so long, as the applicable local law will not permit repatriation
to the United States (the Company hereby agreeing to cause the applicable
Restricted Group Member to promptly take all actions required by the applicable
local law to permit such repatriation) and once such repatriation of any such
affected Net Cash Proceeds is permitted under the applicable local law, such
repatriation will be immediately effected and such repatriated Net Cash Proceeds
will be applied in the manner set forth in this covenant as if the Asset Sale
had occurred on such date; provided that to the extent that the Company has
determined in good faith that repatriation of any or all of the Net Cash
Proceeds of such Asset Sale would have a material adverse tax cost consequence,
the Net Cash Proceeds so affected may be retained by the applicable Restricted
Group Member for so long as such material adverse tax cost event would continue.
 
     If, as of the first day of any calendar month, the aggregate amount of
Excess Proceeds not theretofore subject to an Offer to Purchase pursuant to this
"Limitation on Asset Sales" covenant totals at least $5 million, the Company
must commence, not later than the fifteenth Business Day of such month, and
consummate an Offer to Purchase from the Holders on a pro rata basis an
aggregate Accreted Value of Exchange Notes on the relevant Payment Date equal to
the Excess Proceeds on such date, at a purchase price equal to 101% of the
Accreted Value of the Exchange Notes on the relevant Payment Date, plus, in each
case, accrued interest (if any) to the Payment Date.
 
REPURCHASE OF EXCHANGE NOTES UPON A CHANGE OF CONTROL
 
     The Company must commence, within 30 days of the occurrence of a Change of
Control, and consummate an Offer to Purchase for all Exchange Notes then
outstanding, at a purchase price equal to 101% of the Accreted Value thereof on
the relevant Payment Date, plus accrued interest (if any) to the Payment Date.
 
     There can be no assurance that the Company will have sufficient funds
available at the time of any Change of Control to make any debt payment
(including repurchases of Exchange Notes) required by the foregoing covenant (as
well as may be contained in other securities of the Company which might be
outstanding at the time). The above covenant requiring the Company to repurchase
the Exchange Notes will, unless consents are obtained, require the Company to
repay all indebtedness then outstanding which by its terms would prohibit such
Note repurchase, either prior to or concurrently with such Note repurchase.
 
                                       123
<PAGE>   126
 
COMMISSION REPORTS AND REPORTS TO HOLDERS
 
     At all times from and after the date of the commencement of this Exchange
Offer, the Company shall file with the Commission all such reports and other
information as it would be required to file with the Commission by Sections
13(a) or 15(d) under the Exchange Act if it were subject thereto. The Company
shall supply the Trustee and each Holder or shall supply to the Trustee for
forwarding to each such Holder, without cost to such Holder, copies of such
reports and other information.
 
EVENTS OF DEFAULT
 
     The following events will be defined as "Events of Default" in the
Indenture: (a) default in the payment of principal of (or premium, if any, on)
any Note when the same becomes due and payable at maturity, upon acceleration,
redemption or otherwise; (b) default in the payment of interest on any Note when
the same becomes due and payable, and such default continues for a period of 30
days; (c) default in the performance or breach of the provisions of the
Indenture applicable to mergers, consolidations and transfers of all or
substantially all of the assets of the Company or the failure to make or
consummate an Offer to Purchase in accordance with the "Limitation on Asset
Sales" or "Repurchase of Exchange Notes upon a Change of Control" covenant;
provided that a default or breach of the "Limitation on Asset Sales" covenant
arising from an Involuntary Event shall not constitute an Event of Default
unless such Involuntary Event continues for 90 days; (d) the Company defaults in
the performance of or breaches any other covenant or agreement of the Company in
the Indenture or under the Exchange Notes (other than a default specified in
clause (a), (b) or (c) above) and such default or breach continues for a period
of 60 consecutive days after written notice by the Trustee or the Holders of 25%
or more in aggregate principal amount at maturity of the Exchange Notes,
provided that a default or breach of a covenant or agreement arising from a
Restricted Affiliate ceasing to observe any covenant applicable to it resulting
from an Involuntary Event shall not constitute an Event of Default unless such
Involuntary Event continues for 90 days; (e) there occurs with respect to any
issue or issues of Indebtedness of the Company or any Significant Group Member
having an outstanding principal amount of $5 million or more in the aggregate
for all such issues of all such Persons, whether such Indebtedness now exists or
shall hereafter be created, (I) an event of default that has caused the holder
thereof to declare such Indebtedness to be due and payable prior to its Stated
Maturity and such Indebtedness has not been discharged in full or such
acceleration has not been rescinded or annulled within 30 days of such
acceleration and/or (II) the failure to make a principal payment at the final
(but not any interim) fixed maturity and such defaulted payment shall not have
been made, waived or extended within 30 days of such payment default; provided
that an acceleration or payment default arising from an Involuntary Event shall
not constitute an Event of Default unless such Involuntary Event continues for
90 days; (f) any final judgment or order (not covered by insurance) for the
payment of money in excess of $5 million in the aggregate for all such final
judgments or orders against all such Persons (treating any deductibles,
self-insurance or retention as not so covered) shall be rendered against the
Company or any Significant Group Member and shall not be paid or discharged, and
there shall be any period of 30 consecutive days following entry of the final
judgment or order that causes the aggregate amount for all such final judgments
or orders outstanding and not paid or discharged against all such Persons to
exceed $5 million during which a stay of enforcement of such final judgment or
order, by reason of a pending appeal or otherwise, shall not be in effect;
provided that a final judgment or order arising from an Involuntary Event shall
not constitute an Event of Default unless such Involuntary Event continues for
90 days; (g) a court having jurisdiction in the premises enters a decree or
order for (A) relief in respect of the Company or any Significant Group Member
in an involuntary case under any applicable bankruptcy, insolvency or other
similar law now or hereafter in effect, (B) appointment of a receiver,
liquidator, assignee, custodian, trustee, sequestrator or similar official of
the Company or any Significant Group Member or for all or substantially all of
the property and assets of the Company or any Significant Group Member or (C)
the winding up or liquidation of the affairs of the Company or any Significant
Group Member and, in each case, such decree or order shall remain unstayed and
in effect for a period of 60 consecutive days; or (h) the Company or any
Significant Group Member (A) commences a voluntary case under any applicable
bankruptcy, insolvency or other similar law now or hereafter in effect, or
consents to the entry of an order for relief in an involuntary case under any
such law, (B) consents to the appointment of or taking possession by a receiver,
liquidator, assignee, custodian, trustee, sequestrator or similar official of
the
 
                                       124
<PAGE>   127
 
Company or any Significant Group Member or for all or substantially all of the
property and assets of the Company or any Significant Group Member or (C)
effects any general assignment for the benefit of creditors.
 
     If an Event of Default (other than an Event of Default specified in clause
(g) or (h) above that occurs with respect to the Company) occurs and is
continuing under the Indenture, the Trustee or the Holders of at least 25% in
aggregate principal amount at maturity of the Exchange Notes, then outstanding,
by written notice to the Company (and to the Trustee if such notice is given by
the Holders), may, and the Trustee at the request of such Holders shall, declare
the Accreted Value of, premium, if any, and accrued interest on the Exchange
Notes to be immediately due and payable. Upon a declaration of acceleration,
such Accreted Value of, premium, if any, and accrued interest shall be
immediately due and payable. In the event of a declaration of acceleration
because an Event of Default set forth in clause (e) above has occurred and is
continuing, such declaration of acceleration shall be automatically rescinded
and annulled if the event of default triggering such Event of Default pursuant
to clause (e) shall be remedied or cured by the Company or the relevant
Significant Group Member or waived by the holders of the relevant Indebtedness
within 60 days after the declaration of acceleration with respect thereto. If an
Event of Default specified in clause (g) or (h) above occurs with respect to the
Company, the principal of, premium, if any, and accrued interest on the Exchange
Notes then outstanding shall ipso facto become and be immediately due and
payable without any declaration or other act on the part of the Trustee or any
Holder. The Holders of at least a majority in principal amount at maturity of
the outstanding Exchange Notes by written notice to the Company and to the
Trustee, may waive all past defaults and rescind and annul a declaration of
acceleration and its consequences if (i) all existing Events of Default, other
than the nonpayment of the principal of, premium, if any, and interest on the
Exchange Notes that have become due solely by such declaration of acceleration,
have been cured or waived and (ii) the rescission would not conflict with any
judgment or decree of a court of competent jurisdiction. For information as to
the waiver of defaults, see "-- Modification and Waiver."
 
     The Holders of at least a majority in aggregate principal amount at
maturity of the outstanding Exchange Notes may direct the time, method and place
of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power conferred on the Trustee. However, the Trustee may
refuse to follow any direction that conflicts with law or the Indenture, that
may involve the Trustee in personal liability, or that the Trustee determines in
good faith may be unduly prejudicial to the rights of Holders of Exchange Notes
not joining in the giving of such direction and may take any other action it
deems proper that is not inconsistent with any such direction received from
Holders of Exchange Notes. A Holder may not pursue any remedy with respect to
the Indenture or the Exchange Notes unless: (i) the Holder gives the Trustee
written notice of a continuing Event of Default; (ii) the Holders of at least
25% in aggregate principal amount at maturity of outstanding Exchange Notes make
a written request to the Trustee to pursue the remedy; (iii) such Holder or
Holders offer the Trustee indemnity satisfactory to the Trustee against any
costs, liability or expense; (iv) the Trustee does not comply with the request
within 60 days after receipt of the request and the offer of indemnity; and (v)
during such 60-day period, the Holders of a majority in aggregate principal
amount at maturity of the outstanding Exchange Notes do not give the Trustee a
direction that is inconsistent with the request. However, such limitations do
not apply to the right of any Holder of a Note to receive payment of the
principal of, premium, if any, or interest on, such Note or to bring suit for
the enforcement of any such payment, on or after the due date expressed in the
Exchange Notes, which right shall not be impaired or affected without the
consent of the Holder.
 
     The Indenture will require certain officers of the Company to certify, on
or before a date not more than 90 days after the end of each fiscal year, that a
review has been conducted of the activities of the Company and its Restricted
Group Members and the Company's and its Restricted Group Members' performance
under the Indenture and that the Company has fulfilled all obligations
thereunder, or, if there has been a default in the fulfillment of any such
obligation, specifying each such default and the nature and status thereof. The
Company will also be obligated to notify the Trustee of any default or defaults
in the performance of any covenants or agreements under the Indenture.
 
                                       125
<PAGE>   128
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
     The Company will not consolidate with, merge with or into, or sell, convey,
transfer, lease or otherwise dispose of all or substantially all of its property
and assets (as an entirety or substantially an entirety in one transaction or a
series of related transactions) to, any Person or permit any Person to merge
with or into the Company unless: (i) the Company shall be the continuing Person,
or the Person (if other than the Company) formed by such consolidation or into
which the Company is merged or that acquired or leased such property and assets
of the Company shall expressly assume, by a supplemental indenture, executed and
delivered to the Trustee, all of the obligations of the Company on all of the
Exchange Notes and under the Indenture; (ii) immediately after giving effect to
such transaction, no Default or Event of Default shall have occurred and be
continuing; (iii) immediately after giving effect to such transaction on a pro
forma basis, the Company or any Person becoming the successor obligor of the
Exchange Notes shall have a Consolidated Net Worth equal to or greater than the
Consolidated Net Worth of the Company immediately prior to such transaction;
(iv) immediately after giving effect to such transaction on a pro forma basis
the Company, or any Person becoming the successor obligor of the Exchange Notes,
as the case may be, shall have a Consolidated Leverage Ratio not greater than
110% of the Consolidated Leverage Ratio of the Company immediately prior to the
transaction; and (v) the Company delivers to the Trustee an Officers'
Certificate (attaching the arithmetic computations to demonstrate compliance
with clauses (iii) and (iv)) and Opinion of Counsel, in each case stating that
such consolidation, merger or transfer and such supplemental indenture complies
with this provision, that all conditions precedent provided for herein relating
to such transaction have been complied with and, in the event that the
continuing Person is organized under the laws of any jurisdiction other than the
United States of America or any jurisdiction thereof, that the indenture and the
Exchange Notes constitute legal, valid and binding obligations of the continuing
Person, enforceable in accordance with their terms; provided, however, that
clauses (iii) and (iv) above do not apply if, in the good faith determination of
the Board of Directors of the Company, whose determination shall be evidenced by
a Board Resolution, the principal purpose of such transaction is to change the
state of incorporation of the Company; and provided further that any such
transaction shall not have as one of its purposes the evasion of the foregoing
limitations.
 
DEFEASANCE
 
     Defeasance and Discharge.  The Indenture will provide that the Company will
be deemed to have paid and will be discharged from any and all obligations in
respect of the Exchange Notes on the 123rd day after the deposit referred to
below, and the provisions of the Indenture will no longer be in effect with
respect to the Exchange Notes (except for, among other matters, certain
obligations to register the transfer or exchange of the Exchange Notes, to
replace stolen, lost or mutilated Exchange Notes, to maintain paying agencies
and to hold monies for payment in trust) if, among other things, (A) the Company
has deposited with the Trustee, in trust, money and/or U.S. Government
Obligations that through the payment of interest and principal in respect
thereof in accordance with their terms will provide money in an amount
sufficient to pay the principal of, premium, if any, and accrued interest on the
Exchange Notes on the Stated Maturity of such payments in accordance with the
terms of the Indenture and the Exchange Notes, (B) the Company has delivered to
the Trustee (i) either (x) an Opinion of Counsel to the effect that Holders will
not recognize income, gain or loss for federal income tax purposes as a result
of the Company's exercise of its option under this "Defeasance" provision and
will be subject to federal income tax on the same amount and in the same manner
and at the same times as would have been the case if such deposit, defeasance
and discharge had not occurred, which Opinion of Counsel must be based upon (and
accompanied by a copy of) a ruling of the Internal Revenue Service to the same
effect unless there has been a change in applicable federal income tax law after
the Closing Date such that a ruling is no longer required or (y) a ruling
directed to the Trustee received from the Internal Revenue Service (the "IRS")
to the same effect as the aforementioned Opinion of Counsel and (ii) an Opinion
of Counsel to the effect that the creation of the defeasance trust does not
violate the Investment Company Act of 1940 and after the passage of 123 days
following the deposit, the trust fund will not be subject to the effect of
Section 547 of the United States Bankruptcy Code or Section 15 of the New York
Debtor and Creditor Law, (C) immediately after giving effect to such deposit on
a pro forma basis, no Event of Default, or event that after the giving of notice
or lapse of time or both would become an Event of Default, shall have occurred
and be continuing on the date of such deposit or during the period ending on the
 
                                       126
<PAGE>   129
 
123rd day after the date of such deposit, and such deposit shall not result in a
breach or violation of, or constitute a default under, any other agreement or
instrument to which the Company or any of its Subsidiaries is a party or by
which the Company or any of its Subsidiaries is bound, and (D) if at such time
the Exchange Notes are listed on a national securities exchange, the Company has
delivered to the Trustee an Opinion of Counsel to the effect that the Exchange
Notes will not be delisted as a result of such deposit, defeasance and
discharge.
 
     Defeasance of Certain Covenants and Certain Events of Default.  The
Indenture further will provide that the provisions of the Indenture will no
longer be in effect with respect to clauses (iii) and (iv) under "Consolidation,
Merger and Sale of Assets" and all the covenants described herein under
"Covenants," clauses (c) and (d) under "Events of Default" with respect to such
clauses (iii) and (iv) under "Consolidation, Merger and Sale of Assets" and such
covenants and clauses (e) and (f) under "Events of Default" shall be deemed not
to be Events of Default, upon, among other things, the deposit with the Trustee,
in trust, of money and/or U.S. Government Obligations that through the payment
of interest and principal in respect thereof in accordance with their terms will
provide money in an amount sufficient to pay the principal of, premium, if any,
and accrued interest on the Exchange Notes on the Stated Maturity of such
payments in accordance with the terms of the Indenture and the Exchange Notes,
the satisfaction of the provisions described in clauses (B)(ii), (C) and (D) of
the preceding paragraph and the delivery by the Company to the Trustee of an
Opinion of Counsel to the effect that, among other things, the Holders will not
recognize income, gain or loss for federal income tax purposes as a result of
such deposit and defeasance of certain covenants and Events of Default and will
be subject to federal income tax on the same amount and in the same manner and
at the same times as would have been the case if such deposit and defeasance had
not occurred.
 
     Defeasance and Certain Other Events of Default.  In the event the Company
exercises its option to omit compliance with certain covenants and provisions of
the Indenture with respect to the Exchange Notes as described in the immediately
preceding paragraph and the Exchange Notes are declared due and payable because
of the occurrence of an Event of Default that remains applicable, the amount of
money and/or U.S. Government Obligations on deposit with the Trustee will be
sufficient to pay amounts due on the Exchange Notes at the time of their Stated
Maturity but may not be sufficient to pay amounts due on the Exchange Notes at
the time of the acceleration resulting from such Event of Default. However, the
Company will remain liable for such payments.
 
MODIFICATION AND WAIVER
 
     Modifications and amendments of the Indenture may be made by the Company
and the Trustee with the consent of the Holders of not less than a majority in
aggregate principal amount at maturity of the outstanding Exchange Notes;
provided, however, that no such modification or amendment may, without the
consent of each Holder affected thereby, (i) change the Stated Maturity of the
principal of, or any installment of interest on, any Note, (ii) reduce the
Accreted Value of, or premium, if any, or interest on, any Note, (iii) change
the place or currency of payment of principal of, or premium, if any, or
interest on, any Note, (iv) impair the right to institute suit for the
enforcement of any payment on or after the Stated Maturity (or, in the case of a
redemption, on or after the Redemption Date) of any Note, (v) reduce the
above-stated percentage of outstanding Exchange Notes the consent of whose
Holders is necessary to modify or amend the Indenture, (vi) waive a default in
the payment of principal of, premium, if any, or interest on the Exchange Notes
or (vii) reduce the percentage or aggregate principal amount at maturity of
outstanding Exchange Notes the consent of whose Holders is necessary for waiver
of compliance with certain provisions of the Indenture or for waiver of certain
defaults.
 
NO PERSONAL LIABILITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS, DIRECTORS, OR
EMPLOYEES
 
     The Indenture provides that no recourse for the payment of the principal
of, premium, if any, or interest on any of the Exchange Notes or for any claim
based thereon or otherwise in respect thereof, and no recourse under or upon any
obligation, covenant or agreement of the Company in the Indenture, or in any of
the Exchange Notes or because of the creation of any Indebtedness represented
thereby, shall be had against any
 
                                       127
<PAGE>   130
 
incorporator, stockholder, officer, director, employee or controlling person of
the Company or of any successor Person thereof. Each Holder, by accepting the
Exchange Notes, waives and releases all such liability.
 
CONCERNING THE TRUSTEE
 
     The Indenture provides that, except during the continuance of a Default,
the Trustee will not be liable, except for the performance of such duties as are
specifically set forth in such Indenture. If an Event of Default has occurred
and is continuing, the Trustee will use the same degree of care and skill in its
exercise as a prudent person would exercise under the circumstances in the
conduct of such person's own affairs.
 
     The Indenture and provisions of the Trust Indenture Act of 1939, as
amended, incorporated by reference therein contain limitations on the rights of
the Trustee, should it become a creditor of the Company, to obtain payment of
claims in certain cases or to realize on certain property received by it in
respect of any such claims, as security or otherwise. The Trustee is permitted
to engage in other transactions; provided, however, that if it acquires any
conflicting interest, it must eliminate such conflict or resign.
 
CERTAIN TAX CONSIDERATIONS
 
     Perkins Coie, special tax counsel to the Company, has advised the Company
that because the Exchange Notes should not be considered to differ materially
from the Private Notes, the exchange of the Private Notes for the Exchange Notes
pursuant to the Exchange Offer should not result in any material federal income
tax consequences to Holders. For a full description of the basis of, and
limitations on, this opinion, see "Certain U.S. Federal Income Tax
Considerations."
 
                 CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS
 
     The following discussion, which was prepared by Perkins Coie, special tax
counsel to the Company, summarizes the material U.S. federal income tax
consequences of the exchange of the Private Notes for the Exchange Notes
pursuant to the Exchange Offer. This discussion is based on provisions of the
Internal Revenue Code of 1986, as amended (the "Code"), its legislative history,
judicial authority, current administrative rulings and practice, and existing
and proposed Treasury Regulations, all as in effect and existing on the date
hereof. Legislative, judicial or administrative changes or interpretations after
the date hereof could alter or modify the validity of this discussion and the
conclusions set forth below. Any such changes or interpretations may be
retroactive and could adversely affect a Holder of the Private Notes or the
Exchange Notes.
 
     This discussion does not purport to deal with all aspects of U.S. federal
income taxation that might be relevant to particular Holders in light of their
personal investment or tax circumstances or status, nor does it discuss the U.S.
federal income tax consequences to certain types of Holders subject to special
treatment under the U.S. federal income tax laws, such as certain financial
institutions, insurance companies, dealers in securities or foreign currency,
tax-exempt organizations, foreign corporations or non-resident alien
individuals, or persons holding Private Notes or Exchange Notes that are a hedge
against, or that are hedged against, currency risk or that are part of a
straddle or conversion transaction, or persons whose functional currency is not
the U.S. dollar. Moreover, the affect of any state, local or foreign tax laws is
not discussed.
 
     THE FOLLOWING DISCUSSION IS FOR GENERAL INFORMATION ONLY. EACH HOLDER OF A
PRIVATE NOTE THAT IS PARTICIPATING IN THE EXCHANGE OFFER IS STRONGLY URGED TO
CONSULT WITH ITS OWN TAX ADVISORS TO DETERMINE THE IMPACT OF SUCH HOLDER'S
PARTICULAR TAX SITUATION ON THE ANTICIPATED TAX CONSEQUENCES, INCLUDING THE TAX
CONSEQUENCES UNDER STATE, LOCAL, FOREIGN OR OTHER TAX LAWS OF THE EXCHANGE OF
THE PRIVATE NOTES FOR THE EXCHANGE NOTES PURSUANT TO THE EXCHANGE OFFER.
 
                                       128
<PAGE>   131
 
EXCHANGE OFFER
 
     The exchange of the Private Notes by any Holder for the Exchange Notes
pursuant to the Exchange Offer should not be treated as an "exchange" for
federal income tax purposes because the Exchange Notes should not be considered
to differ materially in kind or extent from the Private Notes. Rather, the
Exchange Notes received by any Holder should be treated as a continuation of the
Private Notes in the hands of such Holder. As a result, there should be no
federal income tax consequences to Holders exchanging the Private Notes for the
Exchange Notes pursuant to the Exchange Offer, and the federal income tax
consequences of holding and disposing of the Exchange Notes should be the same
as the federal income tax consequences of holding and disposing of the Private
Notes. Accordingly, a Holder's adjusted tax basis in the Exchange Notes will be
the same as its adjusted tax basis in the Private Notes exchanged therefor and
its holding period for the Private Notes will be included in its holding period
for the Exchange Notes. Thus, the determination of gain on a sale or other
disposition of the Exchange Notes will be the same as for the Private Notes. In
addition, the Holders must, among other things, continue to include original
issue discount in income as if the exchange had not occurred.
 
                              PLAN OF DISTRIBUTION
 
     This Prospectus, as it may be amended or supplemented from time to time,
may be used by a broker-dealer in connection with resales of any Exchange Notes
received in exchange for Private Notes acquired by such broker-dealer as a
result of market-making or other trading activities. Each broker-dealer that
receives Exchange Notes for its own account in exchange for such Private Notes
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Notes. The Company has
agreed that for a period of up to 180 days after the closing of the Exchange
Offer, it will make this Prospectus, as amended or supplemented, available to
any such brokerdealer that requests copies of this Prospectus in the Letter of
Transmittal for use in connection with any such resale.
 
     The Company will not receive any proceeds from any sale of Exchange Notes
by broker-dealers or any other persons. Exchange Notes received by
broker-dealers for their own account pursuant to the Exchange Offer may be sold
from time to time in one or more transactions in the over-the-counter market, in
negotiated transactions or through the writing of options on the Exchange Notes,
or a combination of such methods of resale, at market prices prevailing at the
time of resale or negotiated prices. Any such resale may be made directly to
purchasers or to or through brokers or dealers who may receive compensation in
the form of commissions or concessions from any such broker-dealer and/or the
purchasers of any such Exchange Notes. Any broker-dealer that resells Exchange
Notes that were received by it for its own account pursuant to the Exchange
Offer in exchange for Private Notes acquired by such broker-dealer as a result
of market-making or other trading activities and any broker-dealer that
participates in a distribution of such Exchange Notes may be deemed to be an
"underwriter" within the meaning of the Securities Act and any profit on any
such resale of Exchange Notes and any commissions or concessions received by any
such persons may be deemed to be underwriting compensation under the Securities
Act. The Letter of Transmittal states that by acknowledging that it will deliver
and by delivering a prospectus, a broker-dealer will not be deemed to admit that
it is an "underwriter" within the meaning of the Securities Act.
 
     The Company has agreed to pay all expenses incident to the Company's
performance of, or compliance with, the Registration Rights Agreement and will
indemnify the holders of Private Notes (including any broker-dealers), and
certain parties related to such holders, against certain liabilities, including
liabilities under the Securities Act.

                          INDEPENDENT AUDITORS' REPORT
 
Board of Directors and Stockholder of
McCaw International, Ltd.
Seattle, Washington
 
   
     We have audited the accompanying balance sheets of McCaw International,
Ltd. and subsidiaries (the Company) as of December 31, 1996 and 1995, and the
related consolidated statements of operations, stockholder's equity, and cash
flows for the years ended December 31, 1996, 1995 and 1994. These consolidated
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audit.
    
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
   
     In our opinion, such financial statements present fairly, in all material
respects, the financial position of the Company at December 31, 1996 and 1995,
and the results of its operations and its cash flows for the years ended
December 31, 1996, 1995 and 1994 in conformity with generally accepted
accounting principles.
    
 
   
     The financial statements give retroactive effect to the mergers of McCaw
International (Services), Ltd. (formerly Special Purpose Company No. 1) and
McCaw International (CANMEX), Ltd. (formerly Nextel Investment Company), with
the Company on January 1, 1997 and March 3, 1997, respectively, which have been
accounted for in a manner similar to poolings of interests as described in Note
1 to the financial statements.

                   MCCAW INTERNATIONAL, LTD. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
              FOR THE YEARS ENDED DECEMBER 31, 1996, 1995 AND 1994
    
 
1.  SIGNIFICANT ACCOUNTING POLICIES
 
   
     BUSINESS ORGANIZATION AND NATURE OF OPERATIONS:  McCaw International, Ltd.
is an indirect, wholly owned subsidiary of Nextel Communications Inc. (Nextel
and its wholly owned subsidiaries are referred to herein as "Nextel"). McCaw
International, Ltd. and subsidiaries (the "Company" or "McCaw") is an
international wireless telecommunications service company. As of December 31,
1996 the Company owns a 100% interest in McCaw Argentina S.A. (McCaw Argentina),
a 30% interest in Infocom Communications Network, Inc. (Infocom), a Philippine
company, accounted for using the equity method, and a contractual right to
receive 25.2% of the profits of the Shanghai GSM System accounted for as a cost
method investment (see note 2).
    
 
   
     As described in Note 2, on January 1, 1997 and March 3, 1997, respectively,
McCaw International (Services), Ltd. (formerly Special Purpose Company No. 1
("SPC#1")) and McCaw International (CAN/MEX), Ltd. (formerly Nextel Investment
Company ("NIC")) became wholly owned subsidiaries of the Company. As these
transactions represent transfers between companies under common control, these
consolidated financial statements have been prepared under a method similar to
the pooling-of-interests method of accounting and reflect the combined financial
position and operating results of the Company, SPC#1 and NIC (collectively
referred to as the "Company") for all periods presented. Accordingly, subsequent
to their issuance, these consolidated financial statements will become the
historical financial statements of the Company.
    
 
     The Company's efforts are primarily directed towards acquiring, developing
and operating wireless communications systems. The Company's ability to generate
positive cash flow and operating profits will depend on a number of factors,
including the ability to attract and retain subscribers, and the successful
deployment and upgrade of its wireless systems in its existing and new markets.
Future results may also be effected by regulatory policies in the various
countries in which the Company operates.
 
     PRINCIPLES OF CONSOLIDATION:  The consolidated financial statements include
the accounts of the Company and its wholly owned subsidiaries. All significant
intercompany transactions and balances have been eliminated in consolidation.
 
     USE OF ESTIMATES:  The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosures of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.
 
   
     The Company is subject to the laws and regulations governing
telecommunication services in effect in each of the countries in which it
operates. These laws and regulations cover, among other things, the number of
licenses that can be used in any one service area by affiliated companies, the
construction and loading requirements necessary to retain a license, the number
of telephone numbers that can be assigned to an individual licensee and the
rights of a licensee to interconnect with the public telecommunications network.
Each of these factors can have a significant influence on the Company's results
of operations and are subject to change by the governmental agency responsible
for determining the laws and regulations in the respective countries. The
financial statements as presented reflect certain assumptions based on laws and
regulations currently in effect in each of the various countries. The Company
cannot predict what future laws and regulations might be passed that could have
a material effect on the Company's results of operations. The Company assesses
the impact of significant changes in laws and regulations on a regular basis and
updates the assumptions used to prepare its financial statements accordingly.

                   MCCAW INTERNATIONAL, LTD. AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
1.  SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)
   
     CASH AND EQUIVALENTS:  The Company considers all highly liquid investments
with an original maturity of three months or less to be cash equivalents. There
was no cash paid for interest or taxes for the years ended December 31, 1996,
1995 or 1994.
    
 
     RADIOS AND ACCESSORIES:  Radios and accessories are held for sale to
customers. Radios and accessories are stated at the lower of cost or market.
Cost is determined using the first-in, first-out method.
 
   
     INTANGIBLE ASSETS:  Intangible assets consist primarily of wireless
licenses which are recorded at cost. Licenses in the countries in which the
Company operates are issued conditionally for various periods of time. The
licenses are generally renewable providing the licensee has complied with
applicable rules and policies. In most instances, the Company believes it has
complied and intends to comply with these standards and is amortizing the
related costs using the straight line method over 20 years. In some cases, the
Company currently is not in compliance with applicable requirements and has
filed requests for extensions with the appropriate government agency. The
Company expects that such extension requests will be granted and the risk of
having these or any other licenses revoked is remote. The Company begins
amortizing the cost of wireless licenses upon commencement of commercial
operations in each market.
    
 
     The carrying value of intangible assets is reviewed for impairment on a
regular basis.
 
   
     INVESTMENTS:  The Company's investment in Clearnet is included in
investments and other assets and classified as available-for-sale as of the
balance sheet date. Accordingly, it is reported at fair value, with unrealized
gains and losses, net of tax, recorded in stockholder's equity. Investments
where the Company does not have the ability to exercise significant influence
over operating and financial policies and that are not considered marketable
instruments are recorded at the lower of cost or market. Realized gains or
losses and declines in value, if any, judged to be other than temporary are
reported in other income or expense.
    
 
   
     Investments where the Company has the ability to exercise significant
influence over operating and financial policies and possesses a voting interest
of less than 50% are accounted for using the equity method. The excess of the
cost of the Company's investments over the net assets acquired is being
amortized over 20 years. Amortization of this excess of $3,677,415, $2,361,428
and $0 for the years ended December 31, 1996, 1995 and 1994, respectively, is
reflected in the accompanying statements of operations in loss from equity
method investments.
    
 
     PROPERTY, PLANT AND EQUIPMENT:  Property, plant and equipment are stated at
cost. Depreciation is provided using the straight line method over estimated
useful lives as follows:
 
<TABLE>
    <S>                                                                       <C>
    Equipment..............................................................   3-10 years
    Computer equipment and software........................................   3-5 years
    Furniture and fixtures.................................................   3 years
    Leasehold improvements.................................................   Life of lease
</TABLE>
 
     Construction in progress includes labor, material, transmission and related
equipment, engineering, site development, capitalized interest, and other costs
relating to the construction and development of wireless networks. The Company
will begin depreciating the cost of the wireless networks over a 10-year period
upon commencement of commercial operations in each market.
 
   
     Expenditures which increase value or extend useful lives are capitalized,
while maintenance and repairs are charged to operations as incurred.
    
 
     The carrying value of property, plant and equipment is reviewed for
impairment on a regular basis.
 
     FOREIGN EXCHANGE:  Financial statement amounts of the Company are expressed
in U.S. dollars. Assets and liabilities are translated at the rate in effect at
the balance sheet date. Revenues and expenses are
 
                                       F-8

translated at the weighted average rate during the period. There were no
translation gains or losses for the years ended December 31, 1996, 1995 and
1994.
    
 
     REVENUE RECOGNITION:  Service revenue will be recorded as revenue when
earned. Sales of equipment and related services will be recorded when goods and
services are delivered. Monthly access charges will be billed in advance and
will be recognized as revenue when the services are provided. Rental fee revenue
and monthly fixed access charges will be recognized in the period service was
provided.
 
     INCOME TAXES:  The Company accounts for U.S. federal income taxes under the
asset and liability method. Under this method, deferred income taxes are
recorded for the temporary differences between the financial reporting basis and
tax basis of the Company's assets and liabilities. These deferred taxes are
measured by the provisions of currently enacted tax laws. The Company is
included in the consolidated tax return of Nextel. However, the income tax
accounts of McCaw International are stated as if the Company filed a separate
return.
 
   
     NET LOSS PER SHARE:  Net loss per share is computed based on the weighted
average number of common shares outstanding during the period.
    
 
   
     NEW ACCOUNTING STANDARDS:  The Financial Accounting Standards Board (FASB)
issued FAS No. 128, entitled "Earnings per Share" and FAS No. 129, entitled
"Disclosure of Information about Capital Structure," which are both effective
for the fiscal year ending December 31, 1997. The Company does not expect any
significant impact on the Company's financial position or results of operations
as a result of adopting these standards.
    
 
   
2.  BUSINESS COMBINATIONS AND INVESTMENTS
    
 
   
     SPECIAL PURPOSE COMPANY NO. 1 AND NEXTEL INVESTMENT COMPANY:  On January 1,
1997, Special Purpose Company No. 1, a wholly owned subsidiary of Nextel, was
merged into the Company and renamed McCaw International (Services), Ltd. ("McCaw
Services"). McCaw Services includes all amounts associated with the Company's
expatriate employees. Subsequent to the merger, all intercompany liabilities
were converted to contributed capital.
    
 
   
     On March 3, 1997, Nextel Investment Company, a wholly owned subsidiary of
Nextel, was merged into the Company and renamed McCaw International (CANMEX),
Ltd. ("Canmex"). Canmex is primarily an investment and asset holding company.
    
 
   
     Immediately prior to the merger, all of Canmex's assets were transferred to
Nextel with the exception of an investment in 38% of the outstanding common
stock of Corporacion Mobilcom, S.A. de C.V. ("Mobilcom") and related assets and
3.7% of the outstanding common stock of Clearnet Communications ("Clearnet").
The remaining intercompany liability was converted to contributed capital
subsequent to the merger.
    
 
   
     As the mergers described above represent transfers of companies under
common control, they have been accounted for in a manner similar to poolings of
interests. The poolings-of-interests method of accounting is intended to present
as a single interest two or more common shareholders' interests which were
previously independent; accordingly, the historical financial statements for the
periods presented prior to the mergers are restated as though the companies had
been combined.

     MCCAW ARGENTINA S.A.:  On August 6, 1996, Nextel contributed its investment
in McCaw Argentina formerly Com Control Comunicacion Controlada S.A., to the
Company, including licenses with a cost of $10.4 million.
 
     As the contribution of McCaw Argentina to the Company is deemed a
reorganization of an entity under common control, the Company's financial
statements reflect the contribution as of November 21, 1995, the date McCaw
Argentina was acquired by Nextel. Accordingly, the financial statements include
the financial position and results of operations of McCaw Argentina beginning
November 21, 1995.
 
     McCaw Argentina has licenses to provide specialized mobile radio (SMR)
services in the Argentine cities of Buenos Aires, Cordoba, Rosario, and Mendoza.
 
   
     On May 6, 1997, the Company contributed its interest in McCaw Argentina
into a joint venture between the Company and Wireless Ventures of Argentina LLC
("WVA"). WVA's contribution included all of the outstanding common stock of a
paging company in Argentina and two companies that own SMR licenses in
Argentina. The Company will have a 50% voting interest and will share equally in
the profits and losses of the joint venture. Capital contributions are to be
made equally by the two parties unless otherwise agreed to by both the Company
and Wireless Ventures of Argentina LLC. The Company will account for its
investment in the joint venture using the equity method.
    
 
   
     INFOCOM COMMUNICATIONS NETWORK, INC.:  On June 14, 1996, the Company
acquired a 30% interest in a Philippine wireless telecommunications company,
Infocom, for $16 million in cash. Infocom provides paging services to
subscribers in the Philippines through a nationwide license granted by the
Philippine government. In addition, Infocom has a nationwide license to provide
ESMR services. The Company's investment in Infocom is accounted for using the
equity method. The excess purchase price over the net assets acquired totaled
$16.2 million and is being amortized over 20 years.

     SHANGHAI GSM SYSTEM:  On October 26, 1995, the Company and Shanghai Science
& Technology Investment Company (SSTIC) formed Shanghai McCaw Telecommunications
Co. Ltd. (Shanghai McCaw), a Chinese equity joint venture in which the Company
maintains a 60% ownership interest. The joint venture's sole purpose is to
facilitate the Company's investment in the Shanghai GSM System. The Company
contributed $9.7 million to Shanghai McCaw to fund the joint venture's
investment in the Shanghai GSM System.
    
 
   
     Under current Chinese law, foreign entities or individuals are prohibited
from participating directly in the ownership and operations of
telecommunications services. Because of this limitation, Shanghai McCaw
participates in the Shanghai GSM System through a profit-sharing arrangement
(the "Unicom Agreement") entered into originally between SSTIC and China United
Telecommunications, Ltd. (Unicom). Accordingly, the Company does not have the
ability to significantly influence the operations of the Shanghai GSM System and
therefore accounts for its investment in Shanghai McCaw under the cost method
(See Note 9).
    
 
   
     Pursuant to the Unicom Agreement, Shanghai McCaw is to receive 42% of the
Shanghai GSM System's net earnings, of which the Company is entitled to 60%.
Accordingly, the Company currently has a contractual right to receive 25.2% of
the earnings of the Shanghai GSM System, representing the consideration for its
cash investments. All assets of the Shanghai GSM System are owned by Unicom. The
Company is not obligated to participate in future capital calls, although
failure to contribute its pro rata share could dilute the Company's right to the
Shanghai GSM System's earnings. Cash payments are made to the Company from
Shanghai McCaw in the form of distributions which are made at the discretion of
the joint venture's Board of Directors. As of March 31, 1997, the Company has
received distributions totaling $1,218,047 which have been remitted to Shanghai
McCaw in the form of a loan (See Note 9).
    
 
   
     On March 29, 1997, Unicom and Shanghai McCaw entered into the Phase III
Unicom Agreement, which modified certain arrangements under the Unicom
Agreement. Pursuant to the Phase III Unicom Agreement (i) Shanghai McCaw has
agreed to provide 60% of the funds required to expand the capacity of the
Shanghai GSM System to provide service for an additional 100,000 subscribers,
which is estimated to be equal to approximately RMB 386.4 million (approximately
US$46.4 million). Pursuant to the Phase III Unicom Agreement (i) the 42% profit
sharing arrangements under the Unicom Agreement were retained for the period up
to the date on which the 50,001st subscriber (currently, there are approximately
25,000 subscribers) of the Shanghai GSM System is activated (the "Phase III
Commencement Date"); (ii) following the Phase III Commencement Date the
allocation of profit sharing arrangement between the parties is revised to
provide Unicom with a greater percentage resulting in Shanghai McCaw receiving
40.2% of the profits of the Shanghai GSM System; (iii) the Phase III Unicom
Agreement expires 14 1/4 years after the Phase III Commencement Date.
    
 
   
     MOBILCOM:  Through a series of investments, from March, 1995 to December,
1996, NIC acquired approximately 30.1% of the outstanding shares of Mobilcom. On
October 24, 1996, as a result of NIC's ownership percentage increasing from
18.5% to 30.1%, the accounting method used to account for this investment was
changed from the cost method to the equity method. The excess purchase price
over net assets acquired recognized as a result of the investments will be
amortized over a period of 20 years.

     During the year ended December 31, 1995, the Company recorded a $15.0
million charge to operations representing an other than temporary decline in
this investment as a result of the decline in the Mexican peso.
    
 
     Mobilcom has licenses to provide SMR services in various cities in Mexico,
including Mexico City, Guadalajara, Monterey, and Tijuana.
 
   
     In January 1997, NIC purchased additional common shares of Mobilcom at a
cost of $16.5 million, in exchange for shares of Nextel Class A Common Stock.
Such purchase increased NIC's ownership interest to approximately 38%.
    
 
     NIC has the right to appoint a majority of Mobilcom board members. In order
to retain the contractual right to designate a majority of the board of
directors of Mobilcom, NIC must invest approximately $76.8 million in Mobilcom
through certain qualified capital transactions by March 1998. As of April 16,
1997, NIC had invested $63.7 million in such qualified capital transactions. NIC
has the option to purchase before March 1998, up to an additional 29.5% of
Mobilcom's common stock. Certain shareholders of Mobilcom retain the right to
approve certain significant transactions such as acquisitions and dispositions,
and the approval of business plans of Mobilcom. In addition, beginning on
October 24, 1997, holders of approximately 33% of the outstanding capital stock
of Mobilcom have the right for two years to put (the Mobilcom Put) the entire
amount of their holding to the company at its appraised fair market value for
cash upon occurrence of certain events. The Mobilcom Put is automatically
exercisable on October 24, 1999.
 
   
     On February 6, 1997, Mobilcom notified each of its shareholders of a $27
million capital call to be funded by March 11, 1997. The Company's pro rata
share of the capital call was approximately $10 million, which was funded by
Nextel. The Company funded an additional $10 million, which increased its equity
interest to approximately 46.3%.
    
 
     Summarized financial information for Mobilcom as of and for the year ended
December 31, 1996 is as follows:
 
<TABLE>
    <S>                                                                       <C>

    Liabilities............................................................    32,856,000

</TABLE>
 
     Effective January 1, 1997, Mobilcom's operations will be considered to be
in a "highly inflationary" economy, as defined in Statement of Financial
Accounting Standards No. 52, Foreign Currency Translations. Accordingly,
Mobilcom will use the U.S. dollar as its functional currency. Mobilcom's income
and expenses will be remeasured at monthly average exchange rates, except for
those related to balance sheet accounts, which will be remeasured at historical
rates. The net gain or loss on remeasurement will be recognized in the results
of operations currently.
 
   
     CLEARNET:  NIC owns 1,596,067 shares of common stock representing 3.7% of
Clearnet. Clearnet provides analog SMR and ESMR services in Canada and holds a
nationwide license to provide PCS services in Canada. The Company's 3.7%
interest in Clearnet is accounted for at fair market value. The market value of
Clearnet common stock at December 31, 1996 was $11 per share.
    
 
     WIRELESS VENTURES OF BRAZIL, INC. AND SUBSIDIARIES (WVB):  On January 30,
1997, Nextel purchased 81% of WVB for $186.3 million in Nextel Class A Common
Stock. Nextel's investment in WVB was simultaneously contributed to the Company.
WVB provides SMR services throughout Brazil. WVB holds licenses for channels in
23 cities in Brazil including Sao Paulo, Rio de Janeiro, Belo Horizonte,
Curitiba, and Brasilia. The acquisition of WVB has been accounted for as a
purchase and is included in McCaw International's fiscal year 1997 consolidated
financial statements.

     On August 23, 1996, the Company advanced Grupo Comunicaciones San Luis,
S.A. de C.V., an investor in Mobilcom, $12.0 million. The principal and interest
outstanding as of December 31, 1996 was $3.4 million. The note bears interest at
a rate of 14.5% and is payable in full on January 13, 1998.
    
 
   
     On September 17, 1996 the Company entered into an agreement with SRI, Inc.
("SRI") and Spectrum Resources of the Northeast ("SRNE") to loan up to $5.0
million to purchase certain specialized mobile radio ("SMR") equipment and
finance other costs related to constructing SMR channels. The note bears
interest at a rate equal to 10.0% per annum and is collateralized with the SMR
equipment and other assets used in construction of the SMR channels. The note
and accrued interest are due in full on the date SRI and SRNE merge with Nextel.
The merger closing date is anticipated to be during the second half of 1997. SRI
and SRNE have borrowed $1.9 million under this loan as of December 31, 1996.
    
 
   
     Notes due from officers of the Company and Nextel earn interest at a rate
of 6% compounded annually. Principal and interest are due at various dates
through January 2000.
    
 
   
     All of the balances outstanding as of December 31, 1996 plus accrued
interest were transferred to Nextel prior to the merger of NIC and the Company.
Accordingly, they have been classified as current.
    
 
   
5.  DUE TO NEXTEL
    
 
   
     The intercompany balance due to Nextel represents costs paid by Nextel on
behalf of the Company since the Company's inception, primarily to fund operating
activities. Included in the balance at December 31, 1996 is a $23.1 million note
payable to Nextel that bears interest at a rate of 7% compounded semi-annually
and is payable in full in October 2006. The remainder of the advance is
non-interest bearing.

5.  DUE TO NEXTEL -- (CONTINUED)
   
     In October 1996, the Company received from Nextel 1.3 million shares of
Nextel Class A Common Stock valued at $23.1 million in exchange for a promissory
note. The stock was subsequently used as consideration to obtain an additional
11.6% interest in Mobilcom. (See Note 2.)
    
 
   
     In February 1997, the Company transferred all of NIC's assets with the
exception of its Clearnet and Mobilcom investment and related assets to Nextel
as repayment for the note payable and intercompany advances received from
Nextel. The remaining outstanding liability due to Nextel was converted to an
additional equity contribution to the Company in connection with the merger of
NIC into the Company. (See Note 2.) Accordingly, they have been classified as
current.
    
 
   
6.  FAIR VALUE OF FINANCIAL INSTRUMENTS
    
 
   
     The estimated fair value amounts have been determined by the Company, using
available market information and appropriate valuation methodologies. However,
considerable judgment is required in interpreting market data to develop the
estimates of fair value. Accordingly, the estimates presented herein are not
necessarily indicative of the amounts that the Company could realize in a
current market exchange. The use of different market assumptions and/or
estimation methodologies may have a material effect on the estimated fair value
amounts.
    
 
   
     The carrying amounts and fair values of the Company's financial instruments
at December 31, 1996 and 1995 are as follows:
    
 
   
     CURRENT ASSETS AND CURRENT LIABILITIES:  The carrying amounts approximate
fair value due to the short-term maturity of these instruments.
    
 
   
     NOTES RECEIVABLE:  The fair value of these noncurrent receivables
approximate book value and are estimated by discounting future cash flows using
current rates at which similar notes would be issued to similar borrowers and
quoted market prices, as applicable.
    
 
   
     INVESTMENTS AND OTHER ASSETS:  Included in investments and others assets is
the Company's investment in Clearnet, which approximates its fair value of
$17,607,000 and $25,505,000 as of December 31, 1996 and 1995, respectively. The
balance also includes the Company's 1.3% interest in non-marketable equity
securities of foreign entities. There is no market for the foreign entities'
common shares, and it was impracticable to estimate the fair market value of the
Company's investment. The investments are carried on the balance sheet at
original cost.
    
 
   
     DUE TO NEXTEL:  The fair value of the $23.1 million note included in due to
Nextel approximates book value and is based on current rates at which the
Company could borrow funds with a similar maturity.
    
 
   
7.  LEASES
    
 
     The Company leases office facilities under operating leases with terms
ranging from 1 to 5 years.
 
     Future minimum lease payments for years ending after December 31, 1996
under operating leases that have initial noncancelable lease terms exceeding one
year are as follows:

     At December 31, 1996, the Company had approximately $6.0 million of
consolidated net operating loss carryforwards for federal income tax purposes
which expire during 2010 and 2011. In addition at December 31, 1996, the Company
had approximately $1.9 million of consolidated net operating loss carryforwards
for Argentinean income tax purposes which expire in 2000 and 2001. The Company
may be limited in its ability to use tax net operating losses in any one year
depending on its ability to generate sufficient taxable income.
    
 
   
9.  RELATED PARTIES
    
 
   
     In 1996, the Company loaned Shanghai McCaw $10.5 million to fund the
buildout of the Shanghai GSM System. The note receivable is part of a total
commitment of $13.2 million, bears interest at 7% per annum and requires
payments of principal and interest in four annual installments, commencing
December 31, 1997. Due to the lack of significant control over the Company's
investment in Shanghai McCaw, the note is recorded as an addition to the
Company's investment in Shanghai McCaw. In addition to the $13.2 million
commitments the Company has committed to lend Shanghai McCaw $2.2 million in the
event of a budget overrun.
    
 
   
     During the year ended December 31, 1996, Nextel has performed certain
administrative functions for the Company, consisting of accounting, legal and
other services, for approximately $504,084, which has been treated as a capital
contribution by the parties. No amounts were incurred for the years ended
December 31, 1995 or 1994 due to the limited operations of the Company.
    
 
     Infocom and the Company have entered into a technical services agreement
pursuant to which the Company has agreed to provide Infocom with engineering and
other technical services, market assistance and system operation assistance. The
agreement was effective beginning, September, 1996 and provides for monthly
payments of $36,000 and has a three year renewal period.
 
     In 1996, the Company entered into a loan agreement (the Argentina SMR
Equipment Financing) with Motorola, Inc., (Motorola) a significant shareholder
of Nextel common stock, to purchase analog SMR equipment in Argentina for $4.1
million. The agreement is collateralized by 100% of McCaw Argentina S.A.
outstanding stock and all of the assets of McCaw Argentina. The loan was due on
March 30, 1997 with interest accruing at 12% per annum unless McCaw Argentina
places an order for iDEN equipment. In such

case, principal is due in October 1999 and interest will be forgiven. As McCaw
Argentina has ordered iDEN equipment from Motorola, the loan has been classified
as long-term.
 
   
     On March 27, 1997, Nextel and Motorola reached agreement on terms and
conditions pursuant to which the Company could access up to $400.0 million of
equipment financing through Motorola, subject to certain per country limits. No
amounts have been borrowed under this agreement by Nextel or the Company to
date.
    
 
   
10.  STOCKHOLDER'S EQUITY
    
 
   
     In connection with the Offering of High-Yield Debt Securities (see Note
13), the board of directors approved a 100,000 for 1 stock split effective prior
to the Initial Offering which resulted in 10 million shares issued and
outstanding. To complete the transaction, the Company increased its authorized
shares from 10,000 to 20 million. Earnings per share for all periods presented
reflect this stock split.
    
 
   
11.  EMPLOYEE BENEFIT PLANS
    
 
   
  Employee Stock Option Plan
    
 
   
     Certain of the Company's employees participate in Nextel's Incentive Equity
Plan (the "Nextel Plan"). Generally, options outstanding under the Nextel Plan
(i) are granted at prices equal to or exceeding the market value of Nextel's
stock on the grant date; (ii) vest ratably over either a four or five year
service period; and (iii) expire ten years subsequent to award.
    
 
   
     A summary of the Nextel Plan activity related to the Company's employees is

     In October 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" ("SFAS 123"). This Statement encourages but does not require
companies to account for employee stock compensation awards based on their
estimated fair value at the grant date with the resulting cost charged to
operations. The Company has elected to continue to account for stock-based
compensation using the intrinsic value method prescribed in Accounting
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees," and
related Interpretations. The effect of applying the fair value method to the
Company's stock-based awards results in net income and earnings per share that
are not materially different from amounts reported.
    
 
  Stock Appreciation Rights
 
   
     On November 1, 1996, the Company adopted a Stock Appreciation Rights Plan
(the "SAR Plan"), which was effective as of November 1, 1995, whereby selected
employees and agents of the Company may be granted rights to share in the future
appreciation in the value of the Company. Such rights do not represent an equity
interest in the Company, only a right to compensation under the terms of the
plan.

11.  EMPLOYEE BENEFIT PLANS -- (CONTINUED)
   
     The Company retroactively granted 1,140,000 rights under the plan, at an
exercise price of $10.00 per right, on dates ranging from October 1, 1995 to
December 31, 1996, with vesting periods of 4 years. Under the provisions of the
plan, the number of shares used in calculating the fair value per share is
adjusted periodically to reflect capital contributed to the Company by its
parent. This adjustment is generally only for purposes of valuing the SAR's. It
does not necessarily reflect the actual issuance of additional shares of common
stock. Rights under the plan may not be exercised until the employee has vested
50% of the grants. As of December 31, 1996 and 1995, there were 1,240,000 and
755,000 rights outstanding, respectively. None of those rights were exercisable
under the terms of the plan. No compensation expense had been recognized and the
Company had no commitment to make payments under the plan at December 31, 1996
and 1995 because there had not been any appreciation in the value of the rights
from the time of issuance to December 31, 1996.
    
 
   
     On June 23, 1997, the board of directors adopted, subject to the approval
of Nextel, the Company's sole shareholder, the 1997 Stock Option Plan and
approved a plan to terminate the SAR Plan. Each holder of SARs granted
previously has been given the right to exchange the SARs for options to be
granted at approximately fair value under the 1997 Stock Option Plan. The
Company expects holders representing a substantial majority of the outstanding
SARs, including all of the members of the Company's senior management team, to
exchange their SARs for options granted under the 1997 Stock Option Plan.
    
 
   
12.  GEOGRAPHIC SEGMENT INFORMATION
    
 
   
     McCaw Argentina represents $22,362,474 and $10,153,502 of total assets as
of December 31, 1996 and 1995, respectively, and operating losses of $2,738,697,
$23,889 and $0 for the years ended December 31, 1996, 1995 and 1994,
respectively.
    
 
   
13.  OFFERING OF HIGH-YIELD DEBT SECURITIES
    
 
   
     In March, 1997, the Company issued through a private placement 951,463
units, each unit representing one senior discount note due 2007 (the Notes) and
one warrant to purchase .10616 shares of common stock (the Warrant). The Notes
are unsecured obligations of the Company and will carry a market interest rate
of 13%. The indenture governing the Notes contains substantial covenants and
restrictions of which the Company currently is in compliance. Proceeds of the
offering, net of issue costs of $16.8 million, were $482 million, with $14.8
million allocated to the Warrants.
    
 
   
     The Warrants may be exercised for $36.45 per share. Interest on the Notes
is payable in cash on each April 15 and October 15, commencing October 15, 2002.
The Notes are redeemable at the option of the Company, in whole or in part, at
any time on or after April 15, 2002.
    
 
   
     On May 7, 1997, the Company filed a registration statement with the
Securities and Exchange Commission in connection with an exchange offer whereby
the holders of the Notes issued in the private placement will be offered the
opportunity to exchange their Notes for publicly tradeable notes.

(1) BASIS OF PRESENTATION
    
 
   
     In the opinion of management, the accompanying unaudited condensed
consolidated financial statements reflect all adjustments, consisting of only
normal recurring accruals, necessary for a fair presentation of the consolidated
financial position of McCaw International, Ltd. and Subsidiaries (the "Company")
as of March 31, 1997, and the results of its operations and cash flows for the
three months ended March 31, 1997 and 1996. The results of operations for the
three months ended March 31, 1997 and 1996 are not necessarily indicative of the
results that may be expected for the full year. These condensed financial
statements are unaudited, and do not include all related footnote disclosures.
    
 
   
     The interim unaudited condensed financial statements should be read in
conjunction with the audited financial statements of the Company.
    
 
   
(2) BUSINESS ACQUISITIONS
    
 
   
  McCaw Brazil
    
 
   
     On January 30, 1997, Nextel purchased 81% of the issued and outstanding
capital stock of Wireless Ventures of Brazil, Inc. ("WVB") from Telcom Ventures,
Inc. and affiliates (Telcom Ventures) in exchange for $186.3 million in Nextel
Class A Common Stock. Nextel's investment in WVB was simultaneously contributed
to the Company, and the Company changed its name to McCaw International
(Brazil), Ltd. ("McCaw Brazil"). McCaw Brazil and its subsidiaries hold licenses
for 1700 channels and provide SMR services in 23 cities in Brazil including Sao
Paulo, Rio de Janiero, Belo Horzonte, Curitiba, and Brazilia. 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 the Company by $215.7.
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. The following summarized pro forma (unaudited) information assumes
the acquisition had occurred on January 1, 1996.

     The above amounts combine the historical results of operations prior to the
merger and reflect adjustments for interest on notes payable forgiven in
connection with the purchase agreement, the recognition of the minority interest
and the amortization of licenses and goodwill.

The Board of Directors of
Wireless Ventures of Brazil, Inc.
Washington, D.C.:
 
     We have audited the accompanying consolidated balance sheet of Wireless
Ventures of Brazil, Inc. and subsidiaries (the Company) as of December 31, 1996,
and the related consolidated statements of operations, stockholders' equity, and
cash flows for the year then ended. These consolidated financial statements are
the responsibility of the Company's management. Our responsibility is to express
an opinion on these consolidated financial statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Wireless Ventures of Brazil,
Inc. and subsidiaries as of December 31, 1996, and the results of their
operations and their cash flows for the year then ended in conformity with
generally accepted accounting principles.

               WIRELESS VENTURES OF BRAZIL, INC. AND SUBSIDIARIES
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                      FOR THE YEAR ENDED DECEMBER 31, 1996
 
1.  DESCRIPTION OF OPERATIONS AND LIQUIDITY
 
   
     Wireless Ventures of Brazil, Inc. (WVB), a Virginia corporation whose
majority stockholder on December 31, 1996 is Telcom Ventures, L.L.C. (Telcom
Ventures), which is a Delaware limited liability company, was organized in
August 1993 for the purpose of pursuing wireless communications investment
opportunities in Brazil. As of December 31, 1996, WVB, through Brazilian
licensee companies, holds licenses to provide a class of mobile
telecommunications services known as specialized mobile radio (SMR) or trunking
services in the 800 MHz frequency band in Brazil. SMR services use radio
frequencies to allow multiple subscribers to communicate between remote portable
or mobile radios.
    
 
     As of December 31, 1996, WVB's subsidiaries held licenses for a total of
1,400 SMR channels in 23 cities in Brazil, including 195 channels in Sao Paulo
and channels in Rio de Janeiro, Belo Horizonte, Curitiba, and Brasilia. The
initial term for such licenses is 15 years, although such licenses are issued at
the sole discretion of the Brazilian Ministry of Communications (the Ministry),
which can seek to cancel the Company's licenses if certain license requirements
are not met. In addition, licensees are required by the Ministry to complete
build-out of the channels and loading of subscribers by a certain date. Failure
to comply with the requirements could result in the revocation of the licenses
by the Ministry. At December 31, 1996, WVB had several channels that had not
been constructed and loaded with subscribers within the specified time frame.
Although there can be no assurance that the Ministry will not revoke these or
any other licenses, the management of WVB has either filed for extensions from
the Ministry or has taken other corrective action and believes the risk of loss
of the licenses due to noncompliance is remote.
 
     In September 1994, WVB formed an indirect wholly owned subsidiary, a
Brazilian service company, AirLink Service e Comercio. Ltda (AirLink). AirLink
holds no licenses but owns equipment and, pursuant to service contracts,
provides technical support, billing, and other administrative functions to the
licensee companies in Brazil.
 
     WVB and its subsidiaries (collectively, "the Company") expect to expand
their operations through continued capital investment in current analog and
future digital technologies to create a national mobile telecommunications
system in Brazil. The Company currently is not generating sufficient cash flows
from operations to support its current operating and capital requirements. The
Company has and will continue to be dependent upon its stockholders to fund
these requirements. The Company's future profitability is dependent upon its
ability to further develop its existing system and successfully market its
mobile radio services in its primary Brazilian markets.
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     PRINCIPLES OF CONSOLIDATION:  The consolidated financial statements include
the accounts of WVB and its direct and indirect wholly owned subsidiaries, Via
Radio Administracao e Participacoes Ltda. (VRA), Air-fone Participacoes e
Empreendimentos Ltda. (Airfone), and AirLink, and its indirect 49 percent
interest in Master-Tec Industria e Comercio de Produtos Eletronicos Ltda.
(Master-Tec), Telemobile Telecomunicacoes Ltda. (Telemobile), Promobile
Telecomunicacoes Ltda. (Promobile), LMP Consultoria e Representacoes Ltda. (LMP)
and Telecomunicacoes Brastel S/C Ltd. (Brastel). VRA wholly owns seven Brazilian
subsidiaries, the accounts of which are consolidated with the accounts of the
Company. In addition, Airfone wholly owns two Brazilian subsidiaries, the
accounts of which are consolidated with the accounts of the Company. WVB
acquired indirect 49 percent interests in MasterTec, Telemobile, Promobile, LMP
and Brastel and has the right to obtain the remaining 51 percent for nominal
consideration when it receives approval from the Ministry. As WVB has effective
control of these five companies, the accounts of Master-Tec, Telemobile,
Promobile, LMP and Brastel are consolidated with the accounts of the Company and
no minority interest is recorded. All significant intercompany balances and
transactions have been eliminated in consolidation.

- ---------------
     (a) Under the respective purchase agreements, the Company has the
         right to obtain the remaining 51 percent for nominal consideration
         when the Ministry approves the transfer of the license rights. As
         of December 31, 1996, these companies had no significant
         operations and their principal assets recorded were represented by
         license rights.
 
     CASH EQUIVALENTS:  For purposes of the statement of cash flows, the Company
considers all highly liquid investments with original maturities of three months
or less to be cash equivalents. Cash equivalents consisted of approximately
$218,111 in overnight investments and short-term deposits as of December 31,
1996.
 
     INVENTORY, NET:  Inventory, which consists primarily of telecommunications
equipment (radios), is stated at the lower of cost or market. Cost is determined
using the first-in, first-out method. The inventory of the Company is subject to
rapid technological changes that could have an adverse financial impact on its
full realization in future periods.
 
     PROPERTY AND EQUIPMENT:  Property and equipment are stated at cost.
Depreciation is computed using the straight-line method over the estimated
useful lives of the assets, which range from 3 to 10 years. Depreciation on
constructed assets, which includes radio towers and analog mobile radio systems,
begins when the assets are substantially completed and ready for their intended
use.
 
     For constructed assets, all costs necessary to bring such assets to the
condition and location necessary for their intended use are initially
capitalized as construction-in-progress and are subsequently transferred to
telecommunications equipment.
 
     LICENSE RIGHTS:  License rights consist of licenses to operate channels for
the provision of SMR services in Brazil. Amortization is calculated on the
straight-line method over 15 years, the initial term of the licenses. The
amortization is also calculated for the licenses of those companies that have
not yet started their operations.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)

     The license rights are held by the Brazilian subsidiaries that WVB has
acquired directly and indirectly, through its holding companies both inside and
outside Brazil from 1993 to 1996. The acquisitions have been accounted for using
the purchase method of accounting. At the time of such acquisitions, a
substantial portion of the purchase cost was allocated to the license rights.
These costs have no basis for income tax reporting purposes. Therefore, the
Company has established a deferred tax liability. This deferred tax liability
was offset by an increase in the acquisition costs of the license rights and is
being amortized over 15 years.
 
     INTANGIBLE ASSETS:  Intangible assets consist of the cost allocated to a
covenant not to compete associated with an acquisition. Amortization is
calculated on the straight-line method over 5 years, the term of the noncompete
arrangement.
 
     REVENUE RECOGNITION:  The Company's principal sources of revenue are the
provision of mobile telecommunications services to businesses and individuals
and the sale and rental of telecommunications equipment (radios) to its service
subscribers. Service revenue consists of a usage fee based on the number of
minutes the subscriber uses each month (airtime revenues) plus a fixed monthly
service fee. Revenue for equipment sales is recognized at the time the
merchandise is shipped. Service and rental revenue are recognized ratably over
the term of the agreements.
 
     FOREIGN CURRENCY TRANSLATION:  The Company accounts for translation of
foreign currency in accordance with Statement of Financial Accounting Standards
No. 52 (SFAS No. 52), Foreign Currency Translations. During the year ended
December 31, 1996, the Company's Brazilian operations were considered to be in a
"highly inflationary" economy, as defined in SFAS No. 52. Accordingly, the
Company uses the U.S. dollar as the functional currency. Therefore, certain
assets and liabilities are remeasured at historical exchange rates while other
assets and liabilities are remeasured at current exchange rates, as follows:
 
     -  Inventories, property and equipment, license rights, and stockholders'
        equity are remeasured at their appropriate current exchange rates.
 
     -  Accounts receivable, other assets, accounts payable and other
        liabilities denominated in U.S. dollars are stated at their actual U.S.
        dollar amounts.
 
     -  Accounts receivable, certain other assets, accounts payable, and other
        liabilities denominated in Brazilian reais are remeasured at the
        commercial transaction foreign exchange rate published by the Brazilian
        Central Bank at the balance sheet date.
 
     -  Income and expenses are remeasured at monthly average exchange rates,
        except for those related to balance sheet accounts remeasured at
        historical rates.
 
     -  The net gain or loss on remeasurement is recognized in the results of
        operations currently.
 
     The remeasurement into U.S. dollar equivalent should not be construed as
representation that the Brazilian real amounts actually represent or have been
or could be converted into U.S. dollars at these or any other rates.
 
     INCOME TAXES:  In accordance with Statement of Financial Accounting
Standards No. 109, Accounting for Income Taxes, the Company uses the asset and
liability method to recognize deferred tax assets and liabilities. Under the
asset and liability method, deferred tax assets and liabilities are recognized
for the future tax consequences attributable to differences between the
financial statement carrying amounts of existing assets and liabilities and
their respective tax bases. Deferred tax assets and liabilities are measured
using enacted tax rates expected to apply to taxable income in the years in
which those temporary differences are expected to be recovered or settled. The
effect on deferred tax assets and liabilities of a change in tax rates is
recognized in income in the period that includes the enactment date.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)

     VAT (ICMS AND ISS TAXES):  The provision of telecommunication services by
the Company's Brazilian subsidiaries is subject to ICMS taxes, a state-level
value-added tax (VAT) levied at a rate of 25 percent. Non-telecommunication
services provided by the Brazilian subsidiaries are subject to ISS taxes, a
municipal service tax levied at rates of five percent or less depending on the
Brazilian city in which the services are provided. The Brazilian subsidiaries
generate revenues that encompass both aspects of telecommunication services and
non-telecommunication services. The management of the Company has adopted an
allocation method for segregating the revenue for tax reporting purposes. The
allocation method utilized by the Company could be subjected to review by the
Brazilian tax authorities and could be altered as a result of such examination.
Accordingly, the Company could be assessed additional taxes by the Brazilian tax
authorities. The management of the Company periodically reviews its allocation
method and accrues additional reserves for taxes to cover such exposure.
Management believes that such assessments, if any, by the Brazilian taxing
authorities would not have a material impact on the financial statements.
 
     CONCENTRATIONS OF RISKS:  Financial instruments that potentially subject
the Company to significant concentrations of credit risk consist principally of
trade accounts receivable. The Company sells its products to commercial and
individual customers in Brazil, and extends credit, generally without requiring
collateral. The Company monitors its exposure for credit losses and maintains
allowances for anticipated losses. Since its inception the Company has suffered
significant credit losses, and these losses could continue in the future. Also,
the Company's core business is in Brazil and its operations may be adversely
affected by economic fluctuations.
 
     USE OF ESTIMATES:  The preparation of the consolidated financial statements
in conformity with generally accepted accounting principles requires management
to make estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenue and expenses during
the reporting period. Actual results could differ from those estimates.
 
     LONG-LIVED ASSETS:  Effective January 1, 1996, the Company adopted
Statement of Financial Accounting Standards No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of."
Long-lived assets and identifiable intangibles held and used are reviewed for
impairment whenever events or changes in circumstances indicate that the
carrying amounts may not be recoverable. Impairment is measured by comparing the
carrying value of the long-lived asset to the estimated undiscounted future cash
flows expected to result from use of the assets and their eventual disposition.
The Company determined that as of December 31, 1996, there had been no
impairment in the carrying value of long-lived assets.

Company entered into an agreement to purchase 49 percent of the capital stock of
Telemobile and Promobile for a total of approximately $6,782,000 with an option
to acquire the remaining 51 percent for no additional purchase price. Prior to
December 31, 1994, $3,000,000 of such purchase price was paid. Telemobile and
Promobile collectively hold licenses to operate 540 channels for the provision
of trunking services in Brazil. Of the remaining balance of the purchase price,
$3,282,000 was paid during 1995 and 1996. The remaining amount of $500,000 is
included in current liabilities within the accompanying consolidated financial
statements, and is expected to be paid prior to December 31, 1997.
 
     The acquisition of Telemobile and Promobile has been accounted for using
the purchase method of accounting. Accordingly, the purchase price was allocated
to the licenses for the 540 channels held by Telemobile and Promobile.
Additionally, the Company established a deferred tax liability in connection
with the acquisition since the license rights acquired have no basis for tax
reporting purposes in Brazil. Such amount has been allocated as an increase in
the license rights acquired.
 
     ACQUISITION OF INTEREST IN LMP:  In May 1996, the Company entered into an
agreement to purchase all of the capital stock of LMP for a total of $900,000.
As of December 31, 1996, $450,000 of such purchase price is included in current
liabilities. Under the terms of the purchase agreement, the remaining purchase
price will be due and payable upon approval from the Ministry for transfer of
control of the licenses. LMP holds licenses to operate 220 SMR channels in
Brazil.

     PURCHASE OF AUGUSTUS AND MULTIPONTO:  In September 1995, the Company
entered into a purchase agreement with Augustus Administracao e Participacoes
S.A. (Augustus) to purchase its 100 SMR channels in Brazil. The total purchase
price is approximately $408,000. Once the Ministry has approved transfer of
control of the SMR licenses from Augustus to the Company, the purchase price
will become due and payable.
 
     In September 1995, the Company entered into a purchase agreement with
Multiponto Telecomunicacoes, Ltda. (Multiponto) to purchase its 200 SMR channels
in Brazil. The total purchase price is approximately $856,800. Once the Ministry
has approved transfer of control of the SMR licenses from Multiponto to the
Company, the purchase price will become due and payable.
 
     These transactions will be reflected in the financial statements on
approval from the Ministry. The Company expects to receive approval for both
transfers from the Ministry by December 31, 1997.

</TABLE>
 
     At December 31, 1996, short-term notes payable consisted of four unsecured
loans from financial institutions in Brazil. These notes are due on various
dates up to June 1997, and carry interest at rates of 4.8 percent and 4.96
percent per month.
 
     At December 31, 1996, the Company had an outstanding bank loan in the
amount of $521,314 from a financial institution in Brazil. This note was
collateralized by discounting with recourse an equal amount of the Company's
trade accounts receivable. The Company must pay a discount rate of 4.5 percent
per month on the outstanding balance.
 
9.  OTHER TAXES PAYABLE
 
     Certain taxes have not been paid at their initial due date. The Company's
management has negotiated with the tax authorities payment extensions in monthly
installments. For the taxes due in 1995, agreements were reached with the tax
authorities for payments in 24 to 68 monthly installments (see detail below).
Such balances are subject to monetary adjustments based on the Brazilian
inflation rates, plus interest at a rate of 1% per month. The taxes due in 1996
are under negotiation and management believes that agreements for payment
extension will be reached with the tax authorities in the near future. Fines and

10.  SHORT-TERM NOTE PAYABLE TO MAJORITY STOCKHOLDER
 
     At December 31, 1996, the Company has a revolving unsecured promissory note
payable to its majority stockholder, Telcom Ventures, in the amount of
$16,973,004. The note bears interest at the rate of 9 percent per annum, and
principal and interest are due on demand. During 1996, the Company recognized
interest expense of $1,378,657 related to this note payable. The note can be
converted to shares of capital stock of WVB at the option of the noteholder.
 
11.  DISTRIBUTION TO SHAREHOLDER
 
     During 1996, the Company distributed to a shareholder $458,000 that
represented contributions made in the prior years in excess of amounts required
under certain capitalization arrangements.

12.  CONTINGENCIES
 
     GENERAL:  There are contingent liabilities of a general nature with respect
to taxes. The Company's tax returns filed in previous years are subject to final
approval by tax authorities. The application of U.S. and Brazilian tax laws to
the Company can be subjective and is dependent upon administrative
interpretations which are subject to change.
 
     RISK OF LICENSE CANCELLATIONS:  As discussed in Note 1, licenses are issued
at the sole discretion of the Brazilian Ministry of Communications, which can
seek to cancel the Company's licenses if certain license requirements are not
met. The Company's strategy is to install the required minimum number of
channels and load them as dictated by the applicable rules and edicts,
particularly when dealing with major cities like the capitals of the various
states. In certain instances, the Company has filed for extensions to the
pre-established installation dates. Management has received no reply to its
extension requests and believes that the Ministry has tacitly approved the
extensions.
 
     Revocation of licenses must be performed by the Ministry in accordance with
applicable rules, which require that the following two conditions be met prior
to revocation:
 
     - The licensee company has not installed and loaded the channels as
       required; and
 
     - Third parties have applied for channels in the same area and the Ministry
       does not have other available radio spectrum to fulfill the application
       requirements.
 
     In certain cases, spectrum has not been available as a result of conflicts
with TV link service providers, who were provided frequencies that have been
subsequently granted to trunking operators. This conflict is regulated by edict
number 1267 dated August 31, 1993, which requires the TV link service providers
to clear these frequencies by established deadlines to permit their use by the
granted trunking operators. The edict established a deadline for the clearing of
channels 70, 77, 78, and 80 by December 1996 and a clearing deadline for
channels 71, 72, and 79 by August 1998. For channels where this conflict exists,
the time period for determining compliance with the channel installation and
loading requirements begins from the date the corresponding channels are cleared
out, rather than the date of grant. Management believes the risk of having these
or any other licenses revoked is remote.
 
13.  FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The following table presents the carrying amounts and estimated fair values
of the Company's financial instruments at December 31, 1996. Statement of
Financial Accounting Standards No. 107, Disclosure about Fair Value of Financial
Instruments, defines the fair value of a financial instrument as the amount at
which the instrument could be exchanged in a current transaction between willing
parties:

13.  FAIR VALUE OF FINANCIAL INSTRUMENTS -- (CONTINUED)

     The following methods and assumptions were used to estimate the fair value
of each class of financial instruments:
 
     - Cash and cash equivalents, trade accounts receivables, due from officers
       and employees, other accounts receivable, accounts payable and accrued
       expenses, bank loans payable, amounts payable for business acquisitions,
       due to affiliates and short-term note payable to majority stockholder:
       the carrying amounts approximate fair values because of the short
       maturity of those instruments.
 
     - Prepaid expenses and other current assets: It is not practicable to
       estimate the fair value since this balance includes amounts related to
       recoverable VAT, which are not transferable, and other prepaid expenses
       that do not have market values.
 
14.  SUBSEQUENT EVENTS
 
     AGREEMENT AND PLAN OF MERGER:  On October 29, 1996, the Company entered
into an Agreement and Plan of Merger (the Merger Agreement) with Nextel
Communications, Inc. (Nextel) and Dial Call Indimich, Inc., a direct wholly
owned subsidiary of Nextel. Pursuant to this Merger Agreement which was
consummated on January 30, 1997, Nextel acquired 81% of the issued and
outstanding capital stock of the Company in exchange for $186,300,000 worth of
Nextel Class A Common Stock in a tax-free reorganization. Under this Merger
Agreement, the existing Company stockholders retained the remaining 19% interest
in the Company. In addition, the Company's common stock was reclassified into
two classes with different voting rights: 1) Nextel acquired 100% of the Class A
common stock, which have 90% of the voting rights, and 2) the existing
stockholders received the Class B common stock, which have 10% of the voting
rights. On the closing date, Nextel contributed its equity interest in the
Company to McCaw International, Ltd. and the Company was renamed McCaw
International (Brazil), Ltd.
 
     STOCK OPTIONS:  The Company had entered into individual stock option
agreements with certain employees of the Company and an affiliate company. These
agreements allowed for such individuals to purchase Company common stock at an
exercise price equal to a pro rata share of the total capital contribution per
share on the option exercise date. The agreements had a five year vesting
period, as well as provisions for immediate vesting in the event of a change of
control. The Merger Agreement, as described above, qualified as a change of
control. Accordingly, these employees would have been entitled to receive a
total of 163,733 shares of Nextel Communications, Inc. common stock, based on an
assumed value of the Company at the time of the merger (i.e., the difference
between the assumed exercise price and the assumed value of the Nextel shares
purchasable as of the merger date), and would not receive any shares of the
Company's common stock. On January 23, 1997, such options were canceled and,
therefore, no compensation expense amounts were recorded for the year ended
December 31, 1996.
 
     REPAYMENT OF NOTE PAYABLE AND RELATED INTEREST PAYABLE:  Pursuant to the
Merger Agreement, the short-term note payable to majority stockholder and the
related interest payable in the amounts of $16,973,004 and $2,060,377,
respectively as of December 31, 1996, were forgiven at the time of the closing
on January 30, 1997.
 
     INFUSION OF CAPITAL:  On February 28, 1997, McCaw International, Ltd.,
infused $5,000,000 of additional paid-in capital to AirLink Servicos e Comercio
Ltda. to repay bank loans and trade payables of the Brazilian subsidiaries.

               WIRELESS VENTURES OF BRAZIL, INC. AND SUBSIDIARIES
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
FOR THE YEAR ENDED DECEMBER 31, 1995 AND THE SIX MONTHS ENDED DECEMBER 31, 1994
 
(1) DESCRIPTION OF OPERATIONS AND LIQUIDITY
 
   
     Wireless Ventures of Brazil, Inc. (WVB), a Virginia corporation whose
majority stockholder on December 31, 1995 is Telcom Ventures, L.L.C. (Telcom
Ventures), a Delaware limited liability company, was organized in August 1993
for the purpose of pursuing wireless communications investment opportunities in
Brazil. As of December 31, 1995, WVB, through Brazilian licensee companies,
holds licenses to provide a class of mobile telecommunications services known as
specialized mobile radio (SMR) or trunking services in the 800 MHz frequency
band in Brazil. SMR services use radio frequencies to allow multiple subscribers
to communicate between remote portable or mobile radios.
    
 
     As of December 31, 1995, WVB's subsidiaries held licenses for a total of
1,140 SMR channels in 23 cities in Brazil, including 195 channels in Sao Paulo,
and channels in Rio de Janeiro, Belo Horizonte, Curitiba, and Brasilia. The
initial term for such licenses is 15 years, although such licenses are issued at
the sole discretion of the Brazilian Ministry of Communications (the Ministry),
which can seek to cancel the Company's licenses at any time. In addition,
licensees are required by the Ministry to complete build-out of the channels and
loading of subscribers by a certain date. Failure to comply with the
requirements could result in the revocation of the licenses by the Ministry. At
December 31, 1995, WVB had several channels which had not been constructed and
loaded with subscribers within the specified timeframe. Although there can be no
assurance that the Ministry will not revoke these or any other licenses, the
management of WVB has either filed for extensions from the Ministry or has taken
other corrective action and believes the risk of loss of the licenses due to
noncompliance is remote.
 
     In September 1994, WVB formed an indirect wholly owned subsidiary, a
Brazilian service company, AirLink Servicos e Comercio, Ltda. (AirLink). AirLink
holds no licenses, but owns equipment and, pursuant to service contracts,
provides technical support, billing, and other administrative functions to the
licensee companies in Brazil.
 
     WVB and its subsidiaries (collectively, the Company) expect to expand their
operations through continued capital investment in current analog and future
digital technologies to create a national mobile telecommunications system in
Brazil. The Company currently is not generating sufficient cash flows from
operations to support its current operating and capital requirements. The
Company has and will continue to be dependent upon its stockholders to fund
these requirements. During 1995 and the six months ended December 31, 1994,
WVB's majority stockholder contributed approximately $800,000 and $13,000,000 to
the Company. Additionally, in 1995 WVB's majority stockholder provided
approximately $12,600,000 to the Company under a short-term unsecured note
payable. Subsequent to year-end, WVB borrowed an additional $3,000,000 under the
note payable agreement (see note 9). The Company's future profitability is
dependent upon its ability to further develop its existing system and
successfully market its mobile radio services in its primary Brazilian markets.
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Principles of Consolidation
 
     The consolidated financial statements include the accounts of WVB and its
direct and indirect wholly owned subsidiaries, Via Radio Administradora e
Participacoes Ltda. (VRA), Airfone Participacoes e Empreendimentos Ltda.
(Airfone), and AirLink, and its indirect 49 percent interest in Master-Tec
Telecomunicacoes Ltda. (Master-Tec), Telemobile-Telecomunicacoes Ltda.
(Telemobile) and Promobile-Telecomunicacoes Ltda. (Promobile). VRA wholly owns
seven Brazilian subsidiaries, the accounts of which are consolidated with the
accounts of the Company. In addition, Airfone wholly owns two Brazilian
subsidiaries, the accounts of which are consolidated with the accounts of the
Company. WVB acquired

indirect 49 percent interests in Master-Tec, Telemobile, and Promobile, and has
the right to obtain the remaining 51 percent when it receives approval from the
Ministry at no additional cost to WVB. As WVB has effective control of these
three companies, the accounts of Master-Tec, Telemobile, and Promobile are
consolidated with the accounts of the Company. All significant intercompany
balances and transactions have been eliminated in consolidation.
    
 
  Cash Equivalents
 
     For purposes of the statement of cash flows, the Company considers all
highly liquid investments with original maturities of 3 months or less to be
cash equivalents. Cash equivalents consisted of approximately $3,686 and $2,460
in overnight investments and short-term deposits as of December 31, 1995 and
1994.
 
  Inventory, Net
 
     Inventory, which consists primarily of telecommunications equipment
(radios), is stated at the lower of cost or market. Cost is determined using the
first-in, first-out (FIFO) method. The inventory of the Company is subject to
rapid technological changes which could have an adverse financial impact on its
full realization in future periods.
 
     Inventory at December 31, 1995 and 1994, includes approximately $786,000
and $328,000, respectively, in rental radios, that have been shipped to
customers under short-term rental agreements. Rental radios are depreciated
using the straight-line method over the estimated useful life of the radios,
which is 5 years.
 
  Property and Equipment
 
     Property and equipment are stated at cost. Depreciation is computed using
the straight-line method over the estimated useful lives of the assets which
range from 3 to 10 years. Depreciation on constructed assets, which include
radio towers and analog mobile radio systems, begins when the assets are
substantially completed and ready for their intended use.
 
     For constructed assets, all costs necessary to bring such assets to the
condition and location necessary for their intended use are initially
capitalized as construction-in-progress and are subsequently transferred to
telecommunications equipment.
 
  License Rights
 
     License rights consist of licenses to operate channels for the provision of
SMR services in Brazil, which had been issued to the licensee companies acquired
(see notes 1 and 4). Amortization is calculated on the straight-line method over
15 years, the initial term of the licenses.
 
  Intangible Assets
 
     Intangible assets consist of the cost allocated to a covenant not to
compete associated with an acquisition. Amortization is calculated on the
straight-line method over 5 years, the term of the non-compete arrangement.
 
  Revenue Recognition
 
     The Company's principal sources of revenue are the provision of mobile
telecommunications services to businesses and individuals and the sale and
rental of telecommunications equipment (radios) to its service subscribers.
Service revenues consist of a usage fee based on the number of minutes the
subscriber uses the system each month (airtime revenues) plus a fixed monthly
service fee, which are recognized when the

merchandise is shipped. Rental revenue is recorded monthly over the term of each
rental agreement.
 
  Foreign Currency Translation
 
     The Company accounts for translation of foreign currency in accordance with
Statement of Financial Accounting Standards No. 52, Foreign Currency
Translations (Statement No. 52). During the year ending December 31, 1995 and
the six months ended December 31, 1994, the Company's Brazilian operations were
considered to be in a "highly inflationary" economy, as such term is defined in
Statement No. 52. Accordingly, the Company uses the U.S. dollar as the
functional currency. Therefore, certain assets and liabilities are translated at
historical exchange rates while other assets and liabilities are translated at
current exchange rates.
 
  Income Taxes
 
     The Company uses the asset and liability method to recognize deferred tax
assets and liabilities. Under the asset and liability method, deferred tax
assets and liabilities are recognized for the future tax consequences
attributable to differences between the financial statement carrying amounts of
existing assets and liabilities and their respective tax bases. Deferred tax
assets and liabilities are measured using enacted tax rates expected to apply to
taxable income in the years in which those temporary differences are expected to
be recovered or settled. The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in income in the period that includes the
enactment date.
 
  ICMS and ISS Taxes
 
     The provision of telecommunication services by the Company's Brazilian
subsidiaries is subject to ICMS taxes, a state level value-added tax (VAT)
levied at a rate of 25 percent. Non-telecommunication services provided by the
Brazilian subsidiaries are subject to ISS taxes, a municipal service tax levied
at rates of 5 percent or less depending on the Brazilian city in which the
services are provided. The Brazilian subsidiaries generate revenues that
encompass both aspects of telecommunication services and non-telecommunication
services. The management of the Company has adopted an allocation method for
segregating the revenue for tax reporting purposes. The allocation method
utilized by the Company could be subjected to review by the Brazilian tax
authorities and could be altered as result of such examination. Accordingly, the
Company could be assessed additional taxes by the Brazilian tax authorities. The
management of the Company periodically reviews its allocation method and accrues
additional reserves for taxes to account for such exposure. Management believes
that such assessments, if any, by the Brazilian taxing authorities would not
have a material impact on the financial statements.
 
  Concentration of Credit Risk
 
     Financial instruments that potentially subject the Company to significant
concentrations of credit risk consist principally of trade accounts receivable.
The Company sells its products to commercial and individual customers in Brazil,
and extends credit, generally without requiring collateral. The Company monitors
its exposure for credit losses and maintains allowances for anticipated losses.
Since inception the Company has suffered significant credit losses, and these
losses could continue in the future.
 
  Pervasiveness of Estimates
 
     The preparation of the consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements

(4) BUSINESS ACQUISITIONS
 
  Acquisition of VR-1
 
     In August 1993, the Company acquired 94 percent, and in July 1994, the
remaining 6 percent, of the capital stock of Via Radio-1 Telecommunicacoes,
S.A., (VR-1), which holds licenses to operate 20 SMR channels in the city of Sao
Paulo, Brazil. The acquisition has been accounted for using the purchase method
of accounting. Accordingly, the purchase price of approximately $743,000,
including acquisition costs, was allocated to assets and liabilities acquired
based on estimates of the fair values of the assets and liabilities as of the
acquisition date, with approximately $555,000 of the purchase price allocated to
the license rights acquired. Such intangible license rights have no basis for
income tax reporting purposes in Brazil thus giving rise to a deferred tax
liability of approximately $454,000, which amount was allocated as an increase
in the value of the license rights acquired (see note 6).
 
     In conjunction with the initial acquisition, in consideration for a
covenant not to compete with the Company for a 5 year period, the Company paid
the former shareholders $250,000. This amount has been included in intangible
assets within the accompanying consolidated financial statements. In November
1994, the ownership of VR-1 was transferred from WVB to VRA.
 
  Acquisition of VRA
 
     In October 1993, WVB, through a holding company, acquired all the
outstanding capital stock of VRA and the four Brazilian subsidiaries that it
then substantially wholly owned. The acquisition has been accounted for using
the purchase method of accounting. The purchase price of approximately
$3,477,000, including acquisition costs, was allocated to the licenses for 80
SMR channels held by VRA's four Brazilian subsidiaries, which have no basis for
income tax reporting purposes in Brazil. Accordingly, the Company established a
deferred tax liability in connection with this acquisition totaling
approximately $2,845,000 (see note 6). Such amount was allocated as an increase
in the value of the license rights acquired.
 
     In November 1993, VRA acquired all of the outstanding capital stock of two
commonly controlled Brazilian companies, K-Tel and ATG Telecommunicacoes e
Comercio, Ltda. (ATG), and its 70 percent

owned subsidiary, Radio Telecommunicacoes do Brazil, Ltda. (Radio-Telecom). ATG
holds licenses to operate 140 SMR channels for the provision of SMR services in
Sao Paulo and several nearby cities. K-Tel held no licenses, but provided
equipment, technical support, and other administrative functions to
approximately 2,300 subscribers as of the acquisition date. The acquisition has
been accounted for using the purchase method of accounting and, accordingly, the
purchase price of approximately $10,300,000 for both companies was allocated to
assets and liabilities acquired based on estimates of fair values as of the date
of acquisition, with approximately $9,021,000 and $1,080,000 of the purchase
price allocated to the ATG license rights and certain telecommunications
equipment maintained by ATG, respectively, with the remaining $199,000 allocated
to the net assets of K-Tel. The intangible license rights acquired have no basis
for income tax reporting purposes in Brazil thus giving rise to deferred tax
liabilities of $8,021,000 (see note 6). Such amounts were allocated as an
increase in the value of the license rights acquired.
 
     In July 1994, VRA acquired the remaining 30 percent of capital stock of
Radio-Telecom for approximately $99,000. The purchase price and the value of
deferred tax liabilities assumed of approximately $81,000 were allocated to the
intangible license rights acquired.
 
     On June 30, 1994, the Company sold all the outstanding shares of capital
stock of K-Tel to Telcom Ventures, the Company's majority shareholder, for its
book value of approximately $199,000.
 
     In connection with the acquisition, the Company became aware of certain tax
contingencies which arose prior to the acquisition. Based on discussion with
legal counsel, management of the Company believes that the probability of a
material impact on the financial statements is remote.
 
  Acquisition of Airfone
 
     In July 1994, the Company indirectly acquired all the outstanding capital
stock of Airfone, which, in turn, held all of the outstanding capital stock of
Airfone Comercio e Servicos de Radiofonia, Ltda. and SOW Comercio e Servicos de
Radiofonia, Ltda. (collectively, the Airfone Affiliates), in exchange for 11.43
percent of the issued and outstanding shares of WVB, the value of which was
determined to be approximately $2,084,000, and the sum of approximately
$5,470,000 in additional purchase price. At the date of acquisition, the Company
had a note receivable of $5,000,000 plus accrued interest of $177,000 due from
the principal stockholders of Airfone. This amount was offset against the
purchase price. The remaining balance of the purchase price of approximately
$293,000 was paid in 1995. The Airfone Affiliates are Brazilian corporations,
which, directly or indirectly, hold licenses to operate a total of 280 SMR
channels in several Brazilian cities.
 
     The acquisition has been accounted for using the purchase method of
accounting. Accordingly, the purchase price totaling approximately $7,555,000,
was allocated to assets and liabilities acquired based on estimates of the fair
values of the assets and liabilities as of the acquisition date, with
approximately $8,161,000 of the purchase price allocated to the license rights
acquired, approximately $566,000 allocated to telecommunications equipment,
accounts receivable and other current assets acquired, and approximately
$1,172,000 allocated to the liabilities assumed. The intangible license rights
acquired have no basis for income tax reporting purposes in Brazil thus giving
rise to deferred tax liabilities of approximately $6,400,000 (see note 6). Such
amount has been allocated as an increase in the license rights acquired.
 
  Acquisition of Interest in Master-Tec
 
     In September 1994, the Company indirectly acquired 49 percent of the
capital stock of Master-Tec for $3,000,000 with an option to acquire the
remaining 51 percent interest for no additional purchase price. Master-Tec is a
Brazilian corporation which holds licenses to operate 100 SMR channels in
several major cities in Brazil. The acquisition has been accounted for using the
purchase method of accounting. Accordingly, the purchase price was allocated to
the licenses for the 100 SMR channels held by Master-Tec. Additionally,

the Company established a deferred tax liability in connection with the
acquisition in the amount of approximately $2,455,000 (see note 6), since the
license rights acquired have no basis for tax reporting purposes in Brazil. Such
amount has been allocated as an increase in the license rights acquired.
 
  Acquisition of Interest in Telemobile and Promobile
 
     In November 1994, the Company entered into an agreement to purchase 49
percent of the capital stock of Telemobile and Promobile for a total of
approximately $6,782,000 with an option to acquire the remaining 51 percent for
no additional purchase price. Prior to December 31, 1994, $3,000,000 of such
purchase price was paid. Telemobile and Promobile collectively hold licenses to
operate 540 channels for the provision of trunking services in Brazil. The
remaining balance of the purchase price of $3,782,000 is included in current
liabilities within the accompanying 1994 consolidated financial statements. Of
the remaining balance, $2,782,000 was paid in 1995, and the Company expects the
remaining amount of $1,000,000 to be paid prior to December 31, 1996.
 
     The acquisition of Telemobile and Promobile has been accounted for using
the purchase method of accounting. Accordingly, the purchase price was allocated
to the licenses for the 540 channels held by Telemobile and Promobile.
Additionally, the Company established a deferred tax liability in connection
with the acquisition in the amount of approximately $5,549,000 (see note 6)
since the license rights acquired have no basis for tax reporting purposes in
Brazil. Such amount has been allocated as an increase in the license rights
acquired.
 
(5) RELATED PARTY TRANSACTIONS
 
     In 1994, LCC, L.L.C. (LCC), an affiliate of Telcom Ventures, performed
design engineering services to develop the Company's mobile radio communications
system in Brazil. Systems development activities included development of terrain
databases, channel loading, preliminary site design, initial frequency planning,
and candidate site evaluation. The cost of such services for the six months
ended December 31, 1994, which was paid by the Company's majority shareholder,
Telcom Ventures, on behalf of the Company, amounted to $524,618 and has been
included in construction-in-progress with a corresponding increase in additional
paid-in capital within the accompanying consolidated financial statements.
 
     During 1995 and the six months ended December 31, 1994, Telcom Ventures
paid certain expenses including salaries, travel, consulting fees, and overhead
expenses totaling $747,450 and $581,809 on behalf of the Company. These amounts
have been reported as selling, general and administrative expenses with a
corresponding increase in additional paid-in capital within the accompanying
consolidated financial statements. During the six months ended 1994, Telcom
Ventures also purchased certain telecommunication equipment and inventory
totaling $472,451 on behalf of the Company. This amount has been reported as an
increase in additional paid-in capital within the accompanying consolidated
financial statements.
 
     In October 1994, LCC licensed its software to the Company for $200,000 per
year over the next five years. The Company's management intends to use such
software to aid in the development of a digital mobile radio communications
system. In March 1996, the software license agreement was amended to make the
software license fee a total of $200,000 for the period commencing October 21,
1994 until December 31, 1997. Accordingly, the license fee of $200,000, which is
due in four installments from June 1996 to December 1996, has been included in
telecommunications equipment and due to affiliates within the accompanying
consolidated financial statements, and is being amortized using the straight
line method over the three year license period. Amortization expense associated
with this software was $24,000 for the year ended December 31, 1995.

     At December 31, 1995, short-term notes payable consisted of three unsecured
loans from financial institutions in Brazil, due on various dates in January
1996 and carrying interest at rates varying from 4.8 percent to 5.1 percent per
month. All principal and interest was repaid in full on the due dates. At
December 31, 1994, short-term notes payable consisted of two unsecured loans
from financial institutions in Brazil carrying interest at rates varying from
9.8 percent to 12.0 percent per month. These loans were repaid during 1995.
 
     At December 31, 1995, the Company had an outstanding bank loan in the
amount of $314,302 from a financial institution in Brazil. This note was
collateralized by discounting with recourse an equal amount of the Company's
trade accounts receivable. The Company must pay a discount rate of 4.5 percent
per month on the outstanding balance. During 1996, the Company has continued to
discount portions of its trade accounts receivable to obtain short-term
financing.
 
     At December 31, 1995, the Company had bank overdrafts of $155,364. At
December 31, 1994, the Company had obtained a bank overdraft facility from a
financial institution in Brazil in the amount of $42,280. This note was
unsecured and carried interest at the rate of 8 percent per month and was repaid
during 1995.
 
(9) SHORT-TERM NOTE PAYABLE TO MAJORITY STOCKHOLDER
 
     At December 31, 1995, the Company has a revolving unsecured promissory note
payable to its majority stockholder, Telcom Ventures, in the amount of
$12,559,670. The note bears interest at the rate of 9 percent per annum and
principal and interest are due on demand. During 1995, the Company recognized

expense of $671,020 related to this note payable. The note can be converted to
shares of capital stock of WVB at the option of the noteholder. As of May 31,
1996, the Company had borrowed an additional $3,051,538 against the promissory
note.
 
(10) PURCHASE OF AUGUSTUS AND MULTIPONTO
 
     In September 1995, the Company entered into a purchase agreement with
Augustus Administracao e Participacoes S.A. (Augustus) to purchase its 100 SMR
channels in Brazil. The total purchase price is approximately $408,000. Once the
Ministry has approved transfer of control of the SMR licenses from Augustus to
the Company, the purchase price will become due and payable.
 
     In September 1995, the Company entered into a purchase agreement with
Multiponto Telecomunicacoes, Ltda. (Multiponto) to purchase its 200 SMR channels
in Brazil. The total purchase price is approximately $856,800. Once the Ministry
has approved transfer of control of the SMR licenses from Multiponto to the
Company, the purchase price will become due and payable.
 
     These transactions will be reflected in the financial statements on
approval from the Ministry. The Company expects to receive approval for both
transfers from the Ministry by December 31, 1996.

          Cash and cash equivalents, trade accounts receivables, due from
     officers and employees, other accounts receivable, trade accounts payable,
     bank loans payable, due to affiliates, and other short-term payables: the
     carrying amounts approximate fair values because of the short maturity of
     those instruments.

          Short-term note payable to majority stockholder: It is not practicable
     to estimate the fair value since the note payable is due to the majority
     stockholder, and although the repayment term is due on demand, the actual
     timing of repayment is uncertain.
 
(12) COMMON STOCK
 
  Stock Split
 
     On August 16, 1994, the Articles of Incorporation of WVB were amended to
increase the authorized capital from 10,000 to 1,000,000 shares of common stock
with the stated par value remaining at $.01 per share. At the same time, WVB
effected a one hundred for one stock split whereby each outstanding share of
common stock was subdivided and reclassified into 100 shares of common stock.
 
  Stock Options
 
     The Company has entered into individual stock option agreements with
certain employees of the Company and an affiliated company. These agreements
allow for such individuals to purchase a total of 1,303 shares, or approximately
2 percent, of the common stock of the Company at an exercise price equal to a
pro rata share of the total capital contribution per share on the option
exercise date, which management believes approximates market value. At December
31, 1995, the per share capital contribution was approximately $428. The
agreements expire in November 1996 and April 1997. As of December 31, 1995, both
options were exercisable and neither had been exercised.
 
(13) STOCK GRANT
 
     In January 1995, the Company entered into an agreement with an employee of
Telcom Ventures, whereby the Company granted such employee 31 shares of common
stock of WVB. The Company recognized compensation expense in the amount of
$12,500, which management believes approximates fair value of the shares
granted. This amount has been reported as selling, general, and administrative
expenses with a corresponding increase in additional paid-in capital within the
accompanying consolidated financial statements.
 
(14) SUBSEQUENT EVENTS
 
     In May 1996, WVB entered into a purchase agreement to acquire the
outstanding capital stock of LMP Consultoria Representcoes Ltd. (LMP) for
$900,000. LMP holds licenses to operate 220 SMR channels in Brazil. By
agreement, payment of one-half of the purchase price is due upon WVB building
out the channels and the balance is due upon obtaining approval from the
Ministry for the transfer of control of the SMR licenses.
 
     In May 1996, WVB entered into a purchase agreement to acquire the
outstanding capital stock of Telecomunicacoes Brastel S/C Ltd. (Brastel) for
$240,000. Brastel holds licenses to operate 40 SMR channels in Brazil. WVB paid
$50,000 of the purchase price upon signing the agreement. The remainder of the
purchase price is due upon WVB building out the channels and obtaining approval
from the Ministry for the transfer of control of the SMR licenses.
 
(15) PENDING SALE OF THE COMPANY
 
     In June 1996, the stockholders of WVB entered into a preliminary agreement
to sell all of the outstanding capital stock of the Company to a U.S. publicly
traded company. Pursuant to the agreement, the shareholders of WVB would receive
common stock of the purchaser as consideration for the sale. The negotiations
are in the preliminary stages, and therefore, are subject to the completion of
due diligence procedures by the purchaser.

(1) BASIS OF PRESENTATION
 
   
     In the opinion of management, the accompanying unaudited condensed
financial statements reflect all adjustments, consisting of only normal
recurring accruals, necessary for a fair presentation of the consolidated
financial position of McCaw International (Brazil), Ltd. and Subsidiaries (the
"Company" or "McCaw Brazil") as of March 31, 1997, and the results of its
operations and cash flows for the three months ended March 31, 1997 and 1996.
The results of operations for the three months ended March 31, 1997 and 1996 are
not necessarily indicative of the results that may be expected for the full
year. These condensed financial statements are unaudited, and do not include all
related footnote disclosures.
    
 
   
     The interim unaudited condensed financial statements should be read in
conjunction with the audited consolidated financial statements of the Company.
    
 
   
(2) MERGER OF COMPANY.
    
 
   
     On October 29, 1996, the Company entered into an Agreement and Plan of
Merger (the Merger Agreement) with Nextel Communications, Inc. (Nextel) and Dial
Call Indimich, Inc., a direct wholly owned subsidiary of Nextel. Pursuant to
this Merger Agreement which was consummated on January 30, 1997, Nextel acquired
81% of the issued and outstanding capital stock of the Company in exchange for
$186.3 million worth of Nextel Class A Common Stock in a tax-free
reorganization. Under this Merger Agreement, the existing Company stockholders
retained the remaining 19% interest in the Company. In addition, the Company's
common stock was reclassified into two classes with different voting rights: 1)
Nextel acquired 100% of the Class A common stock, which have 90% of the voting
rights and 2) the existing stockholders received the Class B common stock, which
have 10% of the voting rights. On the closing date, Nextel contributed its
equity interest in the Company to McCaw International Ltd. and the Company was
renamed McCaw International (Brazil), Ltd.
    
 
   
     The total cost of acquisition, which was accounted for as a purchase, was
$187.2 million and exceeded the net liabilities of the Company by $215.7
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. The following summarized pro forma (unaudited)
information assumes the acquisition had occurred on January 1, 1996.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Stockholders of
  Corporacion Mobilcom, S. A. de C. V. and Subsidiaries:
 
     We have audited the accompanying consolidated balance sheets of Corporacion
Mobilcom, S. A. de C. V. and Subsidiaries as of December 31, 1996 and 1995, and
the related consolidated statements of operations, stockholders' equity and cash
flows for the years then ended (all expressed in thousands of U.S. dollars).
These consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.
 
     We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statements presentation. We believe that our audits provide a
reasonable basis for our opinion.
 
     The accompanying financial statements have been translated in accordance
with the standards set forth in Statements of Financial Accounting Standards No.
52 from Mexican pesos (the functional currency of the Company) into U.S. dollars
(the reporting currency of the Company) for purposes of incorporation into the
consolidated financial statements of McCaw International, Ltd. by the equity
method.
 
     In our opinion, for the purpose of incorporation into the consolidated
financial statements of McCaw International, Ltd. by the equity method, the
translated consolidated financial statement referred to above present fairly, in
all material respects, the financial position of Corporacion Mobilcom, S. A. de
C. V. and Subsidiaries as of December 31, 1996 and 1995, and the results of
their operations, the changes in their stockholders' equity and the changes in
their financial position for the years then ended in conformity with accounting
principles generally accepted in the United States of America.

                 FOR THE YEARS ENDED DECEMBER 31, 1996 AND 1995
                          (THOUSANDS OF U. S. DOLLARS)
 
1.  OPERATIONS
 
     Corporacion Mobilcom, S. A. de C. V. (Mobilcom), is a holding company,
established in 1993. The principal operations of the subsidiary companies of
Mobilcom (the companies) consist of providing specialized mobile radio (SMR)
services to users (subscribers) through licenses granted by the Mexican
Department of Communications and Transportation (SCT) under the terms of the Ley
Federal de Telecomunicaciones (Federal Telecomunications Law) and Ley de Vias
Generales de Comunicacion (General Communications Law and Regulations),
establishing, constructing and exploting, public communication networks for the
transmission of signals between the subscribers' terminal SMR equipment and
interfacing with telecommunication networks authorized by the SCT.
 
     The Companies have licenses that were granted for periods primarily of 15
years and that may be extended under the terms of the licenses granted covering
the principal cities and routes (roads) of Mexico. The terms of the contracts
stipulate that the grantee register the rates of services rendered with the STC.
There is also an obligation to pay the Mexican Federal Government 5% of gross
revenues from the services licensed, as well as an obligation to comply with the
terms established in the licenses granted.
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Significant accounting policies and practices followed by Mobilcom and
subsidiaries (the Company) in the preparation of consolidated financial
statements are described below:
 
          a. PRINCIPLES OF CONSOLIDATION -- The consolidated financial
     statements include the assets, liabilities and results of operations of
     subsidiaries in which Mobilcom owns more than 50% of the voting stock. For
     all periods presented, Mobilcom owns over 99% of the voting stock of its
     consolidated subsidiaries. All significant intercompany balances and
     transactions have been eliminated in consolidation.
 
          The investment in affiliate of which Mobilcom owns less than 50% of
     the stock, is accounted for using the equity method.
 
          b. FOREIGN CURRENCY TRANSLATION -- The Company's accounting records
     are maintained in its functional currency, the Mexican peso. The financial
     statements have been translated into U. S. dollars using the exchange rate
     at each balance sheet date for assets and liabilities and a weighted
     average exchange rate for each period for revenues, expenses, gains, and
     losses. The resulting translation adjustments are recorded as a separate
     component of stockholders' equity.
 
          c. FOREIGN CURRENCY TRANSACTIONS -- Transactions denominated in
     foreign currencies are initially recorded at the prevailing exchange rate
     on the transaction date. Assets and liabilities denominated in foreign
     currencies at year end are recorded at the prevailing exchange rate on the
     balance sheet date. Fluctuations in exchange rates from the transaction
     date to the settlement date or year end are charged to operations.
 
          d. CASH AND CASH EQUIVALENTS -- The Company considers all highly
     liquid, temporary cash investments with original maturities of three months
     or less to be cash equivalents.
 
          e. INVENTORIES -- Inventories are stated at the lower of cost or
     market, as determined using the average cost method.

          f. PROPERTY, FURNITURE AND EQUIPMENT -- Property, furniture and
     equipment are stated at cost. Depreciation is calculated using the
     straight-line method over the estimated useful lives of the assets, as
     follows:

                                                                        USEFUL LIFE
                                                                        -----------
            <S>                                                         <C>

            Computer equipment.......................................      3 years
            Transportation equipment.................................      7 years
</TABLE>
 
          g. REVENUE RECOGNITION -- Service revenue is recognized at the time
     service is rendered. Revenue from the sale of terminal equipment is
     recognized when the goods are delivered and rental from leasing of terminal
     equipment is recognized as rental income is earned.
 
          h. INCOME TAXES -- Income taxes are provided for in accordance with
     Statements of Financial Accounting Standards No. 109, "Accounting for
     Income Taxes" ("SFAS 109"). Under SFAS 109, deferred tax assets and
     liabilities are determined based on differences between the financial
     reporting and tax basis of assets and liabilities and are measured by
     applying enacted tax rates.
 
          i. SENIORITY PREMIUMS AND SEVERANCE COMPENSATION -- Seniority premiums
     and severance compensation which employees are entitled, upon retirement
     after fifteen years or more of service, in accordance with the Mexican
     Federal Labor Law, are recognized as costs during the years in which the
     related services are rendered, based on actuarial calculations. Net
     periodic expense recognized in 1996 and 1995 was $77, and $115
     respectively.
 
          j. CONCENTRATION OF CREDIT RISKS -- The companies provide SMR services
     to subscribers in geographic areas throughout Mexico. The companies do not
     have any single customer which accounts for a significant amount of
     revenues or significant accounts receivables at December 31, 1996 and 1995.
     The companies perform evaluations of their customers' credit histories and
     establish an allowance for doubtful accounts based upon the credit risk of
     specific customers and historical trends.
 
          k. USE OF ESTIMATES -- The preparation of financial statements in
     conformity with generally accepted accounting principles in the United
     States of America requires management to make estimates and assumptions
     that affect the amounts reported in the consolidated financial statements
     and related notes to financial statements. Actual results in such estimated
     may affect amounts reported in future periods.
 
          l. GOODWILL AND COSTS OF LICENSES -- The excess of cost over fair
     value of net assets acquired of subsidiaries and the costs of licenses are
     amortized on a straight-line basis over the estimated economic useful life
     of 25 years.
 
          m. RECLASSIFICATIONS -- Certain 1995 amounts have been reclassified to
     conform with 1996 presentation.
 
3.  FAIR VALUE OF FINANCIAL INSTRUMENT DISCLOSURE
 
     U. S. Statement of Financial Accounting Standards No. 107 ("SFAS No. 107"),
"Disclosures Fair Value of Financial Instruments", requires disclosure of the
estimated fair value of certain financial instruments. The estimated fair value
amounts have been determined using available market information or other
appropriate valuation methodologies that require considerable judgment in
interpreting market data and

developing estimates. Accordingly, the estimates presented herein are not
necessarily indicative of the amounts that the Company could realize in a
current market exchange. The use of different market assumptions and/or
estimation methodologies may have a material effect on the estimated fair value
amounts.
 
     The carrying amounts of the Company's cash equivalents, accounts receivable
and short-term notes payable approximate their fair values. Cash equivalents and
accounts receivable are short-term, in nature and notes payable have relatively
short maturities and bear interest at variable rates tied to market indicators.
The Company's long-term debt consists of debt instruments which bear interest at
fixed rates and variable rates tied to market indicators. Except for long-term
debt due to related parties, the fair value of long-term debt is estimated by
discounting future cash flow amounts using current interest rates at which
similar notes would be issued to similar borrowers. The fair value of these
amounts approximated the carrying value at December 31, 1996 and 1995.
 
     The fair value information presented herein is based on information
available to management as of the above presented dates. Although management is
not aware of any factors that would significantly affect the estimated fair
value, amounts have not been comprehensively revalued for purposes of these
financial statements since those dates and, therefore, the current estimates of
fair value may difference significantly from the amounts presented herein.

(1) During 1994 a Mexican bank made a loan in the amount of U. S. $8,365 to the
    Company collateralized by fixed assets. Additionally in 1994, Arrendadora,
    which is a leasing company, advanced U. S. $14,428 to the Company which was
    used to pay off the loan from the Mexican bank plus accrued interest. The
    advance was made by Arrendadora in anticipation of a sale leaseback
    transaction involving the collateralized equipment. At December 31, 1995,
    the Company was in arrears on accrued interest related to the notes payable
    to Arrendadora in the amount of $1,331 and accordingly the amount was
    classified as current liabilities. The anticipated sale leaseback
    transaction occurred as of June 10, 1996. (See Note 10).

     (2) On February 1997 the capital lease was signed with an effective date of
         June 1996. It establishes some covenants which are not fully complied
         with. See also footnote 9.
    
 
         At December 31, 1996 and 1995, substantially all of the Company's
         property, furniture and equipment was pledged as collateral under the
         Company's notes payable and long-term debt agreements. Additionally, at
         December 31, 1996 and 1995, the shares of one of the Company's
         subsidiaries were pledged as collateral for loans in Mexican pesos. The
         liabilities of such subsidiary exceeded the book value of its assets at
         December 31, 1996 and 1995.
 
11.  STOCKHOLDERS' EQUITY
 
   
     In June 1996, the Company's board of directors agreed to increase the
variable portion of common stock through a 2.65 to 1 stock split, resulting in
the issuance of 292,117 series "B" shares, with a par value of 1,000 Mexican
pesos each. Share data for all periods presented reflect this stock split.
    
 
   
     At December 31, 1996 and 1995 1,304,481 and 971,637 shares of series "B"
shares with a par value of 1,000 Mexican pesos were authorized of which 509,908
and 468,886 shares were issued and outstanding respectively. Prior to March
1995, the company also had series "A" and "C" shares outstanding, all of which
conferred the same rights and privileges to stockholders as series "B" shares.
During 1995 the company exchanged all outstanding series "A" and "C" shares for
series "B" shares.
    
 
   
     During 1996, the following transactions occurred:
    
 
   
        -- The variable portion of common stock was increased through issuance
           of 19,995 series "B" shares, with a par value of 1,000 Mexican pesos
           each. The total subscription value was $8,240, including a premium of
           $5,562, paid in cash and by capitalizing liabilities for $1,030.
    
 
   
        -- The Company's board of directors also agreed to increase the variable
           portion, through issuance of 16,427 series "B" shares, with a par
           value of 1,000 Mexican pesos each; 811 shares were subscribed and
           paid-in by employees, under certain conditions.
    
 
   
        -- Common stock, was increased through payment for 4,600 series "B"
           shares, with a par value of 1,000 Mexican pesos each, in the amount
           of $1,896, including a premium of $1,281.
    
 
   
     During 1995, 87,924 additional shares of common stock were acquired by
Nextel. In conjunction with this purchase, the Company received $12,519 in cash
and contributed $43,625 of debt to capital.

     The Company had net operating loss carryforwards of approximately $57,536

     The Company and its subsidiaries file their tax returns individually and a
consolidated tax return is not prepared.
 
     Even though the Company has incurred tax losses for the past 5 years,
management believes that it is more likely than not that it will generate
taxable income sufficient to realize the portion of the tax benefit associated
with the net deferred tax asset of $2,916 and $3,140 respectively. The belief is
based upon, among other factors, the expected reversal of existing deferred tax
liabilities. If the company is unable to generate sufficient taxable income in
the future through operating results, increases in valuation allowance will be
required through a charge to expense. However, if the Company achieves
sufficient profitability to utilize a greater portion of the deferred tax asset,
the valuation allowance will be reduced through a credit to income.
 
     The actual income tax expense attributable to earnings for the years ended
December 31, 1996 and 1995 differ from the amounts computed by applying the
Mexican income tax rate of 34 percent to losses before income taxes and equity
in the results of affiliate as a result of the following:

13.  ASSOCIATION WITH NEXTEL COMMUNICATIONS, INC. (NEXTEL)
 
   
     On March 3, 1995 Mobilcom had closed a share purchase and subscription
agreement with Nextel, pursuant to which Nextel Investment Company a subsidiary
of Nextel, acquired 16.5% minority interest in Mobilcom. This transaction
reflects the renegotiation of the terms associated with a previously
contemplated transaction involving Nextel, Nextel Investment Company, Mobilcom
and certain stockholders of Mobilcom which was initially announced in October
1994. Pursuant to this transaction, Nextel Investment Company purchased newly
issued shares comprising 16.5% of the shares of capital stock of Mobilcom
(calculated after issuance of such shares) for a cash payment of $12,519 and
$43,625 of notes representing funds advanced to Mobilcom in 1994.
    
 
   
     In addition, Nextel made additional investments in January 1996 for an
additional 1.5% of the shares of capital stock of Mobilcom. (See Note 11). As
part of this transaction, Nextel also received two options to increase its
ownership of Mobilcom equity. The first option was an 18 month option to acquire
an additional 19.5% of Mobilcom for $76,800 and a second option is a three-year
option to acquire an additional 10% of Mobilcom for $67,500.
    
 
     The agreement grants the following privileges to Nextel: (1) certain
preferred rights to acquire additional shares of Mobilcom, in order to maintain
its equity percentage; (2) certain rights to subscribe the shares proposed to be
issued in the transaction; (3) the right to designate members of the Board of
Mobilcom; and (4) veto rights with regard to various matters presented to the
Board of Directors of Mobilcom, including acquisitions, disposals, business
plans and technology rights. This agreement also set the rules for Nextel and
Mobilcom's other stockholders to acquire or dispose of their equity interests in
Mobilcom. Also executed at closing of the Mobilcom transaction were agreement
related to an interpretability relationship between Nextel and Mobilcom and the
sharing between Nextel and Mobilcom of channels along the United States-Mexican
border.
 
   
     At January 31, 1997 Nextel owns 38% of the outstanding shares, of Mobilcom
and still has the option to purchase before March 1998, up to an additional
29.5% of Mobilcom's common stock. Furthermore, certain shareholders of Mobilcom,
holders of approximately 37% of Mobilcom's common stock retain the right for a
period of two years commencing October 24, 1997 to put (the "Mobilcom Put") the
entire amount of their holdings to Nextel at its appraised fair market value for
cash upon the occurrence of certain events (the "Put Events"). The Mobilcom Put
is automatically exercisable on October 24, 1999 whether or not a Put Event
occurs.

14.  SUBSEQUENT EVENTS
 
     (a) On March 10, 1997 the Company has signed a purchase agreement to
acquire the remaining 51% interest in its equity investee, Natel for $6,500,
subject to the approval of the SCT. The company is exploring the possibility of
acquiring additional channels in other markets.
 
   
     On February 6, 1997 the Company requested from its shareholders a capital
call of $27,000 by April 14, 1997. The funds obtained through the capital call
will be used to assist the Company to meet its cash obligations and make certain
strategic investments as follows:

</TABLE>
    
 
   
     Nextel's pro rata share of the capital call is approximately $10,000 which
Nextel has committed to fund. Nextel also expects to fund an additional $12,000
which would increase its equity interest in Mobilcom by approximately 10%.
    
 
   
     (b) At the March 10, 1997 Board meeting, the Company decided to explore the
possibility of disposing of its 400 mhz business which has a net book value of
licenses and equipment of approximately $6,500 as of December 31, 1996. As the
negotiations with potential buyers are in the early stages, there can be no
assurance that a sale will be consummated. Management believes that the disposal
will not result in losses and expects to utilize the proceeds to reduce debt.
Disposition of the 400 mhz business will allow the Company to more effectively
focus on its core business.

               CORPORACION MOBILCOM S.A. DE C.V. AND SUBSIDIARIES
    
 
   
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
    
   
                                  (UNAUDITED)
    
   
                            MARCH 31, 1997 AND 1996
    
   
                          (THOUSANDS OF U.S. DOLLARS)
    
 
   
(1) BASIS OF PRESENTATION
    
 
   
     In the opinion of management, the accompanying unaudited condensed
consolidated financial statements reflect all adjustments, consisting of only
normal recurring accruals, necessary for a fair presentation of the consolidated
financial position of Corporacion Mobilcom. S.A. de C.V. and Subsidiaries (the
"Company") as of March 31, 1997, and the statements of operations and statements
of cash flows for the three months ended March 31, 1997 and 1996. The results of
operations for the three months ended March 31, 1997 and 1996 are not
necessarily indicative of the results that may be expected for the full year.
These condensed consolidated financial statements are unaudited, and do not
include all related footnote disclosures.
    
 
   
     The interim unaudited condensed consolidated financial statements should be
read in conjunction with the audited consolidated financial statements of the
Company.
    
 
   
(2) FOREIGN CURRENCY TRANSLATION
    
 
   
     In accordance with Statement of Financial Accounting Standards No. 52
Foreign Currency Translation the Mexican economy, in which the Company primarily
conducts operations, is considered to be highly inflationary as of January 1,
1997. Accordingly the financial statements have been remeasured to reflect the
U.S. dollar as the functional currency of the Company. Pursuant to SFAS No. 52
the translated December 31, 1996 balance sheet has become the accounting basis
for subsequent periods. Transactions subsequent to January 1, 1997 will be
recorded at current exchange rates with translation gains and losses recorded as
a component of net income before taxes.
    
 
   
     For the three months ended March 31, 1997 net foreign currency gains of
$447 have been recognized as a component of net income.
    
 
   
(3) NOTES PAYABLE AND LONG-TERM DEBT
    
 
   
     The Company was in arrears with respect to principal and interest payments
on certain notes payable and long-term debt agreements as of March 31, 1997.
Consequently certain long-term debt agreements were in technical default as the
Company had not made payment of all of the required installments pursuant to
debt agreements, in addition to non-compliance with other debt covenants.
    
 
   
     During February 1997 the Company placed a capital call to shareholders
requesting $27,000 in additional capital of which $13,619 was contributed during
March 1997. The remaining $13,381 was contributed during April 1997. Portions of
the funds obtained as a result of the capital call were used to make payments on
the portions of debt in arrears and to make advanced payments in anticipation of
certain debt service requirements. As a result of the payments, the Company is
in compliance with its debt covenants.
    
 
   
     Long-term debt has been classified as a non-current liability with the
applicable current portions classified as current liabilities as of March 31,
1997.
    
 
   
(4) SUBSEQUENT EVENTS
    
 
   
     In April 1997 the Company acquired the remaining 51% interest in its equity
investee, Natel. In order to accomplish this transaction the Company contributed
cash to Natel in the amount of $5,356. Concurrently, the other shareholders
holding a 51% interest in Natel received $6,500 from Natel for their interest in
Natel. As a result of the transaction the Company became a 100% owner of Natel.
The excess of the cost to acquire 100% of Natel over the fair value of net
assets acquired of $11,098 is expected to be attributed to the cost of licenses
to be amortized over a period of 25 years. The Company will consolidate Natel
using purchase accounting in subsequent periods.

                                    PART II
 
                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Article TENTH of the Registrant's Articles of Incorporation, as amended
(the "Articles of Incorporation"), provides that no director of the Registrant
shall be personally liable for any monetary damages for any breach of fiduciary
duty as a director, except to the extent that the Washington Business
Corporation Act prohibits the elimination or limitation of liability of
directors for breach of fiduciary duty.
 
     Article ELEVENTH of the Registrant's Articles of Incorporation provides
that a director or officer of the Registrant shall be indemnified by the
Registrant to the fullest extent of the law against all expense, liability and
loss (including attorneys' fees, judgments, fines, ERISA excise taxes or
penalties and amounts to be paid in settlement) actually and reasonably incurred
in connection with any litigation or other legal proceeding brought against him
or her or otherwise involving him or her (including as a witness) by virtue of
his or her position as a director or officer of the Registrant. Notwithstanding
the foregoing, the Registrant shall indemnify an officer or director in
connection with a proceeding initiated by such director or officer only if such
proceeding was authorized by the board of directors of the Registrant. The right
to indemnification includes the right to be paid expenses incurred in defending
any proceeding in advance of its final disposition, provided that such director
or officer undertakes to repay all amounts advanced if it is ultimately
determined that he or she is not entitled to indemnification under Article
ELEVENTH.
 
     If the Registrant fails to make an indemnification payment within 60 days
(20 days in the case of a claim for expenses incurred in defending any
proceeding in advance of its final disposition) after receipt of a written claim
for such payment, the director or officer may bring suit against the Registrant
to recover the unpaid amount of the claim, and to the extent successful, may
also recover the expense of prosecuting such claim. A director or officer will
be presumed to be entitled to indemnification upon submission of a written
claim, and the Registrant will have the burden of proof to overcome such
presumption. Neither failure of the Registrant to make a prior determination
that indemnification is proper nor an actual determination that such director or
officer is not so entitled shall be a defense to such an action or create a
presumption that the director or officer is not so entitled.
 
     Article ELEVENTH of the Registrant's Articles of Incorporation further
provides that the indemnification therein is not exclusive, and provides that in
the event that the Washington Business Corporation Act is amended to expand the
indemnification permitted to directors and officers, the Registrant must
indemnify those persons to the fullest extent permitted by such law as so
amended.
 
     Chapter 23B.08.510 of the Washington Business Corporation Act provides that
a corporation has the power to indemnify a director of the corporation against
amounts paid and expenses incurred in connection with a proceeding to which he
or she is made a party by reason of such position, if such person shall have
acted in good faith and reasonably believed, in the case of conduct in the
director's official capacity, that such conduct was in the best interests of the
corporation, and in all other cases, that such person's conduct was not opposed
to the best interests of the corporation, and, in any criminal proceeding, that
such person had no reasonable cause to believe his conduct was unlawful;
provided that, in the case of actions brought by or in the right of the
corporation, no indemnification shall be made with respect to any matter as to
which such person shall have been adjudged to be liable to the corporation or in
connection with any proceeding charging improper personal benefit to the
director, whether or not involving action in the director's official capacity,
in which the director was adjudged liable on the basis of an improper personal
benefit.
 
     Chapter 23B.08.570 of the Washington Business Corporation Act provides that
the corporation may indemnify an officer, employee or agent of the corporation
for expenses to the same extent as a director.

ITEM 22.  UNDERTAKINGS
 
     1. The undersigned Registrant hereby undertakes as follows: that prior to
any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.
 
     2. The Registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (1) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415, will be filed as a part of an
amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
 
     3. The undersigned Registrant hereby undertakes that insofar as
indemnification for liabilities arising under the Securities Act of 1933 may be
permitted to directors, officers and controlling persons of the Registrant
pursuant to the foregoing provisions, or otherwise, the Registrant has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim of indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
 
     4. The undersigned Registrant hereby undertakes that, for the purposes of
determining any liability under the Securities Act of 1933, each post-effective
amendment that contains a form of prospectus shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

expire and all rights of the Holders of such Warrants shall terminate.
Additionally, pursuant to Section 4.1(j)(ii) hereof, the Warrants shall expire
and all rights of the Holders of such Warrants shall terminate in the event the
Company merges or consolidates with or sells all or substantially all of its
property and assets to a Person (other than an Affiliate of the Company) if the
consideration payable to holders of Common Stock in exchange for their Common
Stock in connection with such merger, consolidation or sale consists solely of
cash or in the event of the dissolution, liquidation or winding up of the
Company.

                 Section 3.3.  Method of Exercise; Payment of Exercise Price.
In order to exercise all or any of the Warrants represented by a Warrant
Certificate, the Holder thereof must surrender for exercise the Warrant
Certificate to the Warrant Agent at its corporate trust office address set
forth in Section 12.5 hereof, with the Subscription Form set forth on the
reverse of the Warrant Certificate duly executed, together with payment in full
of the Exercise Price then in effect for each Common Share (or other
securities) issuable upon exercise of the Warrants as to which a Warrant is
exercised; such payment may be made in cash or by certified or official bank or
bank cashier's check payable to the order of the Company and shall be made to
the Warrant Agent at its corporate trust office address set forth in Section
12.5 hereof prior to the close of business on the date the Warrant Certificate
is surrendered to the Warrant Agent for exercise.  Notwithstanding the
foregoing, if the Common Shares (or other securities) issuable upon exercise of
the Warrants are registered under the Exchange Act, the Exercise Price may be
paid by surrendering additional Warrants to the Warrant Agent having an
aggregate Spread equal to the aggregate Exercise Price of the Warrants being
exercised.  All payments received upon exercise of Warrants shall be delivered
to the Company by the Warrant Agent as instructed in writing by the Company.
If less than all the Warrants represented by a Warrant Certificate are
exercised, such Warrant
<PAGE>   17
                                       13


Certificate shall be surrendered and a new Warrant Certificate of the same
tenor and for the number of Warrants which were not exercised shall be executed
by the Company and delivered to the Warrant Agent and the Warrant Agent shall
countersign the new Warrant Certificate, registered in such name or names as
may be directed in writing by the Holder, and shall deliver the new Warrant
Certificate to the Person or Persons entitled to receive the same.  Upon the
exercise of any Warrants following the surrender of a Warrant Certificate in
conformity with the foregoing provisions, the Warrant Agent shall instruct the
Company to transfer promptly to the Holder or, upon the written order of the
Holder of such Warrant Certificate, appropriate evidence of ownership of any
Common Shares or other security or property to which it is entitled, registered
or otherwise placed in such name or names as may be directed in writing by the
Holder, and to deliver such evidence of ownership to the Person or Persons
entitled to receive the same and fractional shares, if any, or an amount in
cash, in lieu of any fractional shares, as provided in Section 4.5 hereof;
provided that the Holder of such Warrant shall be responsible for the payment
of any transfer taxes required as the result of any change in ownership of such
Warrants or the issuance of such Common Shares other than to the Holder of such
Warrants.  Upon the exercise of a Warrant or Warrants, the Warrant Agent is
hereby authorized and directed to requisition from any transfer agent of the
Common Shares (and all such transfer agents are hereby irrevocably authorized
to comply with all such requests) certificates (bearing the legend set forth in
Section 12.10 hereof, if applicable, unless a Registration Statement relating
to such Common Shares shall then be in effect or the Company and the Holder
exercising such Warrant or Warrants otherwise agree) for the necessary number
of Common Shares to which said Holder may be entitled.  The Company shall
enter, or shall cause any transfer agent of the Common Shares to enter, the
name of the Person entitled to receive the Common Shares upon exercise of the
Warrants into the Company's register of shareholders within 14 days of such
exercise.  A Warrant shall be deemed to have been exercised immediately prior
to the close of business on the date of the surrender for exercise, as provided
above, of the Warrant Certificate representing such Warrant and, for all
purposes under this Agreement, the Person entitled to receive any Common Shares
deliverable upon such exercise shall, as between such Person and the Company,
be deemed to be the Holder of such Common Shares of record as of the close of
business on such date and shall be entitled to receive, and the Warrant Agent
shall deliver to such Person, any Common Shares  to which such Person would
have been entitled had such Person been the registered holder on such date.

                 Section 3.4.  Repurchase Offers.  (a)  Notice of Repurchase
Event.  Within five Business Days following the occurrence of a Repurchase
Event, the Company shall give notice (a "Repurchase Notice") to the Holders of
the Warrants and the Warrant Agent that such event has occurred.

                 (b)      Repurchase Offers Generally.  Following the
occurrence of a Repurchase Event, the Company shall offer to repurchase for
cash all outstanding Warrants pursuant to the provisions of this Section 3.4 (a
"Repurchase Offer").  The Company shall
<PAGE>   18
                                       14


give notice of a Repurchase Offer in accordance with Section 3.4(f) hereof.
Each date on which the Company gives any such notice is referred to as the
"Notice Date."  The Repurchase Offer shall commence on the Notice Date for such
Repurchase Offer and shall expire at 5:00 p.m., New York City time, on a date
determined by the Company (the "Final Surrender Time") that is at least 30 but
not more than 60 days after the Notice Date.  Once a Repurchase Event has
occurred, there is no limit on the number of Repurchase Offers that the Company
may make.

                 (c)      Repurchase Offers.  (i)  In any Repurchase Offer, the
Company shall offer to purchase for cash at the Repurchase Price all Warrants
outstanding on the Notice Date for such Repurchase Offer that are properly
tendered to the Warrant Agent on or prior to the Final Surrender Time for such
Repurchase Offer.

                 (ii)     Each Holder may, but shall not be obligated to,
accept such Repurchase Offer by tendering to the Warrant Agent, on or prior to
the Final Surrender Time for such Repurchase Offer, the Warrant Certificates
evidencing the Warrants such Holder desires to have repurchased in such offer,
together with a completed Certificate for Surrender in substantially the form
attached to the Warrant Certificate.  A Holder may withdraw all or a portion of
the Warrants tendered to the Warrant Agent at any time prior to the Final
Surrender Time for such Repurchase Offer.  If less than all the Warrants
represented by a Warrant Certificate shall be tendered, such Warrant
Certificate shall be surrendered and a new Warrant Certificate of the same
tenor and for the number of Warrants which were not tendered shall be executed
by the Company and delivered to the Warrant Agent and the Warrant Agent shall
countersign the new Warrant Certificate, registered in such name or names as
may be directed in writing by the Holder, and shall deliver the new Warrant
Certificate to the Person or Persons entitled to receive the same; provided
that the Holder of such Warrants shall be responsible for the payment of any
transfer taxes required as the result of any change in ownership of such
Warrants.

                 (d)      Repurchase Price.  (i)  The purchase price (the
"Repurchase Price") for each Warrant properly tendered to the Warrant Agent
pursuant to a Repurchase Offer shall be equal to the value (the "Relevant
Value") on the Valuation Date of the Common Shares issuable, and other
securities or property of the Company which would have been delivered, upon
exercise of Warrants had the Warrants been exercised (regardless of whether the
Warrants are then exercisable), less the Exercise Price in effect on the Notice
Date for such Repurchase Offer.

                 (ii)     The Relevant Value of the Common Shares and other
securities or property issuable upon exercise of all the Warrants, on any
Valuation Date shall be:

                 (1)      (A) If the Common Shares (or other securities) are
         registered under the Exchange Act, deemed to be the average of the
         daily market prices (on the stock
<PAGE>   19
                                       15


         exchange that is the primary trading market for the Common Shares (or
         other securities)) of the Common Shares (or other securities) for the
         20 consecutive trading days immediately preceding such Valuation Date
         or, (B) if the Common Shares (or other securities) have been
         registered under the Exchange Act for less than 20 consecutive trading
         days before such date, then the average of the daily market prices for
         all of the trading days before such date for which daily market prices
         are available, in the case of each of (A) and (B), as certified to the
         Warrant Agent by the President, any Vice President or the Chief
         Financial Officer of the Company (the "Value Certificate").  The
         market price for each such trading day shall be:  (A) in the case of a
         security listed or admitted to trading on any national securities
         exchange, the closing sales price on such day, or if no sale takes
         place on such day, the average of the closing bid and asked prices on
         such day, (B) in the case of a security not then listed or admitted to
         trading on any national securities exchange, the last reported sale
         price on such day, or if no sale takes place on such day, the average
         of the closing bid and asked prices on such day, as reported by a
         reputable quotation source designated by the Company, (C) in the case
         of a security not then listed or admitted to trading on any national
         securities exchange and as to which no such reported sale price or bid
         and asked prices are available, the average of the reported high bid
         and low asked prices on such day, as reported by a reputable quotation
         service, or a newspaper of general circulation in the Borough of
         Manhattan, City and State of New York customarily published on each
         Business Day, designated by the Company, or, if there shall be no bid
         and asked prices on such day, the average of the high bid and low
         asked prices, as so reported, on the most recent day (not more than 30
         days prior to the date in question) for which prices have been so
         reported and (D) if there are no bid and asked prices reported during
         the 30 days prior to the date in question, the Relevant Value shall be
         determined as if the Common Shares (or other securities) were not
         registered under the Exchange Act; or

                 (2)      If the Common Shares (or other securities) are not
         registered under the Exchange Act or if the value cannot be computed
         under clause (1) above, deemed to be equal to the value set forth in
         the Value Report (as defined below) as determined by an Independent
         Financial Expert, which shall be selected by the Board of Directors in
         accordance with Section 3.4(e) hereof, and retained on customary terms
         and conditions, using one or more valuation methods that the
         Independent Financial Expert, in its best professional judgment,
         determines to be most appropriate but without giving effect to any
         discount for lack of liquidity, the fact that the Company has no class
         of equity securities registered under the Exchange Act or the fact
         that the Common Shares and other securities or property issuable upon
         exercise of the Warrants represent a minority interest in the Company.
         The Company shall cause the Independent Financial Expert to deliver to
         the Company, with a copy to the Warrant Agent, within 45 days of the
         appointment of the Independent Financial Expert in accordance with
         Section 3.4(e) hereof, a value report (the "Value Report") stating the
<PAGE>   20
                                       16


         Relevant Value of the Common Shares and other securities or property
         of the Company, if any, being valued as of the Valuation Date and
         containing a brief statement as to the nature and scope of the
         methodologies upon which the determination of Relevant Value was made.
         The Warrant Agent shall have no duty with respect to the Value Report
         of any Independent Financial Expert, except to keep it on file and
         available for inspection by the Holders.  The determination as to
         Relevant Value in accordance with the provisions of this Section
         3.4(d) shall be conclusive on all Persons.  The Independent Financial
         Expert shall consult with management of the Company in order to allow
         management to comment on the proposed Relevant Value prior to delivery
         to the Company of any Value Report of the Independent Financial
         Expert.

                 (e)      Selection of Independent Financial Expert.  If clause
(d)(ii)(2) is applicable, the Board of Directors of the Company shall select an
Independent Financial Expert not more than five Business Days following a
Repurchase Event.  Within two days after such selection of the Independent
Financial Expert, the Company shall deliver to the Warrant Agent a notice
setting forth the name of such Independent Financial Expert.

                 (f)      Notice of Repurchase Offer.  Each notice of a
Repurchase Offer (an "Offer Notice") given by the Company pursuant to Section
3.4(b)(i) shall be given by the Company directly to all Holders of the
Warrants, with a copy to the Warrant Agent, shall be given simultaneously with
the Repurchase Notice (or, in the event that the Relevant Value of the Common
Shares or other securities or property issuable upon exercise of all the
Warrants cannot be determined pursuant to Section 3.4(d)(ii)(1), then such
Offer Notice shall be given within five Business Days after the Company
receives the Value Report with respect to such offer) and shall specify (A) the
Final Surrender Time for such Repurchase Offer, (B) the manner in which
Warrants may be surrendered to the Warrant Agent for repurchase by the Company,
(C) the Repurchase Price at which the Warrants will be repurchased by the
Company, (D) if applicable, the name of the Independent Financial Expert whose
valuation of the Common Shares and other securities or property was utilized in
connection with determining such Repurchase Price and (E) that payment of the
Repurchase Price will be made by the Warrant Agent.  Each such notice shall be
accompanied by a Certificate for Surrender for Repurchase Offer in
substantially the form attached to the Warrant Certificate and a copy of the
Value Report, if any.

                 (g)      Payment for Warrants.  Upon surrender for repurchase
of any Warrants in conformity with the provisions of this Section 3.4, the
Warrant Agent shall thereupon promptly notify the Company of such surrender.
On or before the Final Surrender Time for any Repurchase Offer, the Company
shall deposit with the Warrant Agent funds sufficient to make payment for the
Warrants tendered to the Warrant Agent and not withdrawn.  After receipt of
such deposit from the Company, the Warrant Agent shall make payment, by
delivering a check in such amount as is appropriate, to such Person or
<PAGE>   21
                                       17


Persons as it may be directed in writing by the Holder surrendering such
Warrants, net of any transfer taxes required to be paid in the event that the
check is to be delivered to a Person other than the Holder.

                 (h)      Compliance with Laws.  Notwithstanding anything
contained in this Section 3.4, if the Company is required to comply with laws
or regulations in connection with making any Repurchase Offer, such laws or
regulations shall govern the making of such Repurchase Offer.

                                   ARTICLE IV

                                  ADJUSTMENTS

                 Section 4.1.  Adjustments.  The Exercise Price and the number
of Common Shares issuable upon exercise of each Warrant shall be subject to
adjustment from time to time as follows:

                 (a)      Divisions; Consolidations; Reclassifications.  In
case the Company shall, on or before the Expiration Date, (i) issue any Common
Shares in payment of a dividend or other distribution with respect to its
Common Shares, (ii) subdivide its issued and outstanding Common Shares, (iii)
consolidate its issued and outstanding Common Shares into a smaller number of
shares, or (iv) reclassify or convert the Common Shares (other than a
reclassification in connection with a merger, consolidation or other business
combination which will be governed by Section 4.1(j)), then the number of
Common Shares purchasable upon exercise of each Warrant immediately prior to
the record date for such issue or distribution or the effective date of such
subdivision, consolidation, reclassification or conversion shall be adjusted so
that the Holder of each Warrant shall thereafter be entitled to receive the
kind and number of Common Shares which such Holder would have been entitled to
receive after the happening of any of the events described above had such
Warrant been exercised immediately prior to the happening of such event or any
record date with respect thereto.  An adjustment made pursuant to this Section
4.1(a) shall become effective immediately after the effective date of such
event retroactive to the record date, if any, for such event.

                 (b)      Rights; Options; Warrants.  In case the Company shall
issue rights, options, warrants or convertible or exchangeable securities
(other than an issuance of convertible or exchangeable securities subject to
Section 4.1(a)) to all holders of its Common Shares, entitling them to
subscribe for or purchase Common Shares at a price per share which is lower (at
the record date for such issuance) than the then Current Market Value per
Common Share, then the Company shall ensure that at the time of such issuance,
the same or a like offer or invitation is made to the Holders of the Warrants
as if their Warrants had been exercised on the day immediately preceding the
record date of such offer or invitation
<PAGE>   22
                                       18


on the terms (subject to any adjustment pursuant to Section 4.1(a) for a prior
event) on which such Warrants could have been exercised on such date; provided
that if the Board so resolves, the Company shall not be required to ensure that
the same offer or invitation is made to the Holders of the Warrants, but the
number of Common Shares thereafter purchasable upon the exercise of each
Warrant shall instead be adjusted and shall be determined by multiplying the
number of Common Shares theretofore purchasable upon exercise of each Warrant
by a fraction, the numerator of which shall be the sum of (i) the number of
Common Shares outstanding immediately prior to the issuance of such rights,
options, warrants or convertible or exchangeable securities plus (ii) the
number of additional Common Shares which may be purchased or subscribed for
upon exercise, exchange or conversion of such rights, options, warrants or
convertible or exchangeable securities and the denominator of which shall be
the sum of (x) the number of Common Shares outstanding immediately prior to the
issuance of such rights, options, warrants or convertible or exchangeable
securities plus (y) the number of shares which the total consideration received
by the Company for such rights, options, warrants or convertible or
exchangeable securities so offered would purchase at the then Current Market
Value per Common Share.  Except as otherwise provided above, such adjustment
shall be made whenever such rights, options, warrants or convertible or
exchangeable securities are issued, and shall become effective retroactively
immediately after the record date for the determination of shareholders
entitled to receive such rights, options, warrants or convertible or
exchangeable securities.

                 (c)      Issuance of Common Shares at Lower Values.  In case
the Company shall sell and issue any Common Share or Right (as defined below)
(excluding (i) any Right issued in any of the transactions described in Section
4.1(a) or (b) above, (ii) Common Shares issued pursuant to (x) any Rights
outstanding on the date of this Agreement or any Right issued in any
transaction described in Section 4.1(a) or (b) above and (y) a Right, if on the
date such Right was issued, the exercise, conversion or exchange price per
Common Share with respect thereto was at least equal to the then Current Market
Value per Common Share and (iii) any Common Shares or Right issued as
consideration when any corporation or business is acquired, merged into or
becomes part of the Company or a subsidiary of the Company in an arm's-length
transaction between the Company and a Person other than an Affiliate of the
Company) at a price per Common Share (determined in the case of any such Right,
by dividing (x) the total consideration receivable by the Company in
consideration of the sale and issuance of such Right, plus the total
consideration payable to the Company upon exercise, conversion or exchange
thereof, by (y) the total number of Common Shares covered by such Right) that
is lower than the Current Market Value per Common Share in effect immediately
prior to such sale or issuance, then the number of Common Shares thereafter
purchasable upon the exercise of each Warrant shall be determined by
multiplying the number of Common Shares theretofore purchasable upon exercise
of such Warrant by a fraction, the numerator of which shall be the number of
Common Shares outstanding immediately after such sale or issuance and the
denominator of which shall be the number of Common Shares outstanding
immediately prior to such sale or issuance plus the number of
<PAGE>   23
                                       19


Common Shares which the aggregate consideration received (determined as
provided below) for such sale or issuance would purchase at such Current Market
Value per Common Share.  For purposes of this Section 4.1(c), the Common Shares
which the holder of any such Right shall be entitled to subscribe for or
purchase shall be deemed to be issued and outstanding as of the date of such
sale and issuance and the consideration received by the Company therefor shall
be deemed to be the consideration received by the Company for such Right, plus
the consideration or premiums stated in such Right to be paid for the Common
Shares covered thereby.  In case the Company shall sell and issue any Right
together with one or more other securities as part of a unit at a price per
unit, then in determining the "price per Common Share" and the "consideration
received by the Company" for purposes of the first sentence of this Section
4.1(c), the Board shall determine, in good faith, the fair value of the Right
then being sold as part of such unit.  For purposes of this paragraph, a
"Right" shall mean any right, option, warrant or convertible or exchangeable
security containing the Right to subscribe for or acquire one or more Common
Shares, excluding the Warrants.  This Section 4.1(c) shall not apply to: (i)
the exercise of Warrants, or the conversion or exchange of other securities
convertible or exchangeable for Common Shares; or (ii) Common Shares issued
upon the exercise of Rights or warrants issued to all holders of Common Shares.

                 (d)      Distributions of Debt, Assets, Subscription Rights or
Convertible Securities.  In case the Company shall make a distribution to all
holders of its Common Shares of evidences of its indebtedness, or assets, or
other distributions (excluding any issuance of Common Shares referred to in
Section 4.1(a) above and excluding distributions in connection with the
dissolution, liquidation or winding-up of the Company which shall be governed
by Section 4.1(j) and distributions of securities referred to in Section
4.1(a), Section 4.1(b) or Section 4.1(c)), then, in each case, the number of
Common Shares purchasable after such record date upon the exercise of each
Warrant shall be determined by multiplying the number of Common Shares
purchasable upon the exercise of such Warrant immediately prior to such record
date by a fraction, the numerator of which shall be the Current Market Value
per Common Share immediately prior to the record date for such distribution and
the denominator of which shall be the Current Market Value per Common Share
immediately prior to the record date for such distribution less the then fair
value (as determined in good faith by the Board) of the evidences of its
indebtedness, or assets or other distributions so distributed attributable to
one Common Share.  Such adjustment shall be made whenever any such distribution
is made, and shall become effective on the date of distribution retroactive to
the record date for the determination of shareholders entitled to receive such
distribution.

                 (e)      Expiration of Rights, Options and Conversion
Privileges.  Upon the expiration of any rights, options, warrants or conversion
or exchange privileges (including without limitation any Rights) that have
previously resulted in an adjustment hereunder, if any thereof shall not have
been exercised, exchanged or converted, the Exercise Price and the number of
Common Shares issuable upon the exercise of each Warrant shall, upon such
<PAGE>   24
                                       20


expiration, be readjusted and shall thereafter, upon any future exercise, be
such as they would have been had they been originally adjusted (or had the
original adjustment not been required, as the case may be) as if (i) the only
Common Shares so issued were the Common Shares, if any, actually issued or sold
upon the exercise, exchange or conversion of such rights, options, warrants or
conversion or exchange rights (including without limitation any Rights) and
(ii) such Common Shares, if any, were issued or sold for the consideration
actually received by the Company upon such exercise, exchange or conversion
plus the consideration, if any, actually received by the Company for issuance,
sale or grant of all such rights, options, warrants or conversion or exchange
rights (including without limitation any Rights) whether or not exercised.

                 (f)      Current Market Value.  For the purposes of any
computation under this Article IV, the "Current Market Value" per Common Share
or of any other security (herein collectively referred to as a "security") at
any date herein specified shall be:

                 (i)      if the security is not registered under the Exchange
         Act, the value of the security (1) most recently determined as of a
         date within the six months preceding such date by an Independent
         Financial Expert selected by the Company in accordance with the
         criteria for such valuation set out in Section 4.1(k), or (2) if no
         such determination shall have been made within such six-month period
         or if the Company so chooses, determined as of such a date by an
         Independent Financial Expert selected by the Company in accordance
         with the criteria for such valuation set out in Section 4.1(k), or

                 (ii)     if the security is registered under the Exchange Act,
         the average of the daily market prices of the security for the 20
         consecutive trading days immediately preceding such date or, if the
         security has been registered under the Exchange Act for less than 20
         consecutive trading days before such date, then the average of the
         daily market prices for all of the trading days before such date for
         which daily market prices are available.  The market price for each
         such trading day shall be:  (A) in the case of a security listed or
         admitted to trading on any national securities exchange, the closing
         sales price, regular way, on such day, or if no sale takes place on
         such day, the average of the closing bid and asked prices on such day
         on the principal national securities exchange on which such security
         is listed or admitted, as determined by the Board, in good faith, (B)
         in the case of a security not then listed or admitted to trading on
         any national securities exchange, the last reported sale price on such
         day, or if no sale takes place on such day, the average of the closing
         bid and asked prices on such day, as reported by a reputable quotation
         source designated by the Company, (C) in the case of a security not
         then listed or admitted to trading on any national securities exchange
         and as to which no such reported sale price or bid and asked prices
         are available, the average of the reported high bid and low asked
         prices on such day, as reported by a reputable quotation service, or a

         general circulation in the Borough of Manhattan, City and State of New
         York customarily published on each Business Day, designated by the
         Company, or, if there shall be no bid and asked prices on such day,
         the average of the high bid and low asked prices, as so reported, on
         the most recent day (not more than 30 days prior to the date in
         question) for which prices have been so reported and (D) if there are
         no bid and asked prices reported during the 30 days prior to the date
         in question, the Current Market Value of the security shall be
         determined as if the security were not registered under the Exchange
         Act.

                 (g)      Consideration Received.  For purposes of any
computation respecting consideration received pursuant to this Section 4.1, the
following shall apply:

                 (i)      in the case of the issuance of Common Shares for
         cash, the consideration shall be the amount of such cash, provided
         that in no case shall any deduction be made for any commissions,
         discounts or other expenses incurred by the Company for any
         underwriting of the issue or otherwise in connection therewith;

                 (ii)     in the case of the issuance of Common Shares for a
         consideration in whole or in part other than cash, the consideration
         other than cash shall be deemed to be the fair market value thereof as
         determined in good faith by the Board (irrespective of the accounting
         treatment thereof), whose determination shall be conclusive and
         described in reasonable detail in a board resolution which shall be
         provided as soon as practicable thereafter to the Warrant Agent; and

                 (iii)    in the case of the issuance of rights, options,
         warrants or securities convertible into or exchangeable for Common
         Shares (including any Rights), the aggregate consideration received
         therefor shall be deemed to be the consideration received by the
         Company for the issuance of such rights, options, warrants or
         securities convertible into or exchangeable for Common Shares, plus
         the additional minimum consideration, if any, to be received by the
         Company upon the exercise, conversion or exchange thereof (the
         consideration in each case to be determined in the same manner as
         provided in clauses (i) and (ii) of this Section 4.1(g)).

                 (h)      De Minimis Adjustments.  No adjustment in the number
of Common Shares purchasable hereunder shall be required unless such adjustment
would require an increase or decrease of at least one percent (1%) in the
number of Common Shares purchasable upon the exercise of each Warrant;
provided, however, that any adjustments which by reason of this Section 4.1(h)
are not required to be made shall be carried forward and taken into account in
any subsequent adjustment.  All calculations shall be made to the nearest
one-thousandth of a share.

                 (i)      Adjustment of Exercise Price.  Whenever the number of
Common Shares purchasable upon the exercise of each Warrant is adjusted, as
herein provided, the Exercise Price per Common Share payable upon exercise of
such Warrant shall be adjusted (calculated to the nearest $.01) so that it
shall equal the price determined by multiplying such Exercise Price immediately
prior to such adjustment by a fraction the numerator of which shall be the
number of Common Shares purchasable upon the exercise of each Warrant
immediately prior to such adjustment and the denominator of which shall be the
number of Common Shares so purchasable immediately thereafter.  Following any
adjustment to the Exercise Price pursuant to this Article IV, the amount
payable, when adjusted, shall never be less than the par value per Common Share
at the time of such adjustment.

                 If after an adjustment, a Holder of a Warrant upon exercise of
it may receive shares of two or more classes in the capital of the Company, the
Company shall determine the allocation of the adjusted Exercise Price between
such classes of shares in a manner that the Board deems fair and equitable to
the Holders.  After such allocation, the exercise privilege and the Exercise
Price of each class of shares shall thereafter be subject to adjustment on
terms comparable to those applicable to Common Shares in this Article IV.

                 Such adjustment shall be made successively whenever any event
listed above shall occur.

                 (j)      Consolidation, Merger, Etc.  (i)  Subject to the
provisions of Subsection (ii) below of this Section 4.1(j), in case of the
consolidation of the Company with, or merger of the Company with or into, or of
the sale of all or substantially all of the properties and assets of the
Company to, any Person, and in connection therewith consideration is payable to
holders of Common Shares (or other securities or property purchasable upon
exercise of Warrants) in exchange therefor, the Warrants shall remain subject
to the terms and conditions set forth in this Agreement and each Warrant shall,
after such consolidation, merger or sale, entitle the Holder to receive upon
exercise the number of shares in the capital or other securities or property
(including cash) of or from the Person resulting from such consolidation or
surviving such merger or to which such sale shall be made or of the parent of
such Person, as the case may be, that would have been distributable or payable
on account of the Common Shares if such Holder's Warrants had been exercised
immediately prior to such merger, consolidation or sale (or, if applicable, the
record date therefor); and in any such case the provisions of this Agreement
with respect to the rights and interests thereafter of the Holders of Warrants
shall be appropriately adjusted by the Board in good faith so as to be
applicable, as nearly as may reasonably be, to any shares, other securities or
any property thereafter deliverable on the exercise of the Warrants.

                 (ii)     Notwithstanding the foregoing, (x) if the Company
         merges or consolidates with, or sells all or substantially all of its
         property and assets to, another Person (other than an Affiliate of the
         Company) and consideration is payable to holders of Common Shares in
         exchange for their Common Shares in connection with such merger,
         consolidation or sale which consists solely of cash, or (y) in the
         event of the dissolution, liquidation or winding up of the Company,
         then the Holders of Warrants shall be entitled to receive
         distributions on the date of such event on an equal basis with holders
         of Common Shares (or other securities issuable upon exercise of the
         Warrants) as if the Warrants had been exercised immediately prior to
         such event, less the Exercise Price.  Upon receipt of such payment, if
         any, the rights of a Holder shall terminate and cease and such
         Holder's Warrants shall expire.  If the Company has made a Repurchase
         Offer that has not expired at the time of such transaction, the
         holders of the Warrants will be entitled to receive the higher of (i)
         the amount payable to the holders of the Warrants described above and
         (ii) the Repurchase Price payable to the holders of the Warrants
         pursuant to such Repurchase Offer.  In case of any such merger,
         consolidation or sale of assets, the surviving or acquiring Person
         and, in the event of any dissolution, liquidation or winding up of the
         Company, the Company shall deposit promptly with the Warrant Agent the
         funds, if any, necessary to pay the Holders of the Warrants.  After
         receipt of such deposit from such Person or the Company and after
         receipt of surrendered Warrant Certificates, the Warrant Agent shall
         make payment by delivering a check in such amount as is appropriate
         (or, in the case of consideration other than cash, such other
         consideration as is appropriate) to such Person or Persons as it may
         be directed in writing by the Holder surrendering such Warrants.

                 (k)      If required pursuant to Section 4.1(f)(i), the
Current Market Value shall be deemed to be equal to the value set forth in the
Value Report (as defined below) as determined by an Independent Financial
Expert, which shall be selected by the Board in its sole discretion, and
retained on customary terms and conditions, using one or more valuation methods
that the Independent Financial Expert, in its best professional judgment,
determines to be most appropriate.  The Company shall cause the Independent
Financial Expert to deliver to the Company, with a copy to the Warrant Agent,
within 45 days of the appointment of the Independent Financial Expert, a value
report (the "Value Report") stating the value of the Common Shares and other
securities or property of the Company, if any, being valued as of the Valuation
Date and containing a brief statement as to the nature and scope of the
examination or investigation upon which the determination of value was made.
The Warrant Agent shall have no duty with respect to the Value Report of any
Independent Financial Expert, except to keep it on file and available for
inspection by the Holders.  The determination as to Current Market Value in
accordance with the provisions of this Section 4.1(k) shall be conclusive on
all Persons.  The Independent Financial Expert shall consult with management of
the Company in order to allow management to comment on the proposed value prior
to delivery to the Company of any Value Report.

                 (l)      When No Adjustment Required.  No adjustment need be
                          made for:

                 (i)      grants or exercises of Rights granted to employees of
                          the Company or any of its subsidiaries or Common
                          Shares issued or granted to such employees, whether
                          or not upon the exercise, exchange or conversion of
                          any such Rights (to the extent that all such
                          securities do not have an aggregate value in excess
                          of 15% of the equity value of the Company on a fully
                          diluted basis, as determined in good faith by the
                          Board);

                 (ii)     options, warrants or other agreements or rights to
                          purchase capital stock of the Company entered into
                          prior to the date of the issuance of the Warrants;

                 (iii)    rights to purchase Common Shares pursuant to a
                          Company plan for reinvestment of dividends or 
                          interest; and

                 (iv)     a change in the par value of the Common Shares
                          (including a change from par value to no par value 
                          or vice versa).

                 To the extent the Warrants become convertible into cash, no
adjustment need be made thereafter as to the cash.  Interest will not accrue on
the cash.

                 Section 4.2.  Notice of Adjustment.  Whenever the number of
Common Shares purchasable upon the exercise of each Warrant or the Exercise
Price is adjusted, as herein provided, the Company shall cause, so far as it is
able, the Warrant Agent promptly to mail, at the expense of the Company, to
each Holder notice of such adjustment or adjustments and shall deliver to the
Warrant Agent a certificate of the Auditors setting forth the number of Common
Shares purchasable upon the exercise of each Warrant and the Exercise Price
after such adjustment, setting forth a brief statement of the facts requiring
such adjustment and setting forth the computation by which such adjustment was
made.  Such certificate shall be conclusive evidence of the correctness of such
adjustment except in the case of manifest error.  The Warrant Agent shall be
entitled to rely on such certificate and shall be under no duty or
responsibility with respect to any such certificate, except to exhibit the
same, from time to time, to any Holder desiring an inspection thereof during
reasonable business hours upon reasonable notice.  The Warrant Agent shall not
at any time be under any duty or responsibility to any Holders to determine
whether any facts exist which may require any adjustment of the Exercise Price
or the number of Common Shares purchasable on exercise of the Warrants or any
of the other adjustments set forth in Section 4.1, or with respect to the
nature or extent of any such adjustment when made, or with respect to the
method employed in making such adjustment, or the validity or value (or the
kind or amount) of any Common Shares which may be purchasable on exercise of
the Warrants.  The Warrant Agent shall not be responsible for any failure of
the Company to
<PAGE>   29
                                       25


make any cash payment or to issue, transfer or deliver any Common Shares or
share certificates upon the exercise of any Warrant.

                 Section 4.3.  Statement on Warrants.  Irrespective of any
adjustment in the Exercise Price or the number or kind of shares purchasable
upon the exercise of the Warrants, Warrants theretofore or thereafter issued
may continue to express the same price and number and kind of shares as are
stated in the Warrants initially issuable pursuant to this Agreement.

                 Section 4.4.  Notice of Consolidation, Merger, Etc.  In case
at any time after the date hereof and prior to 5:00 p.m. (New York City time)
on the Expiration Date, there shall be any (i) consolidation or merger
involving the Company or sale, transfer or other disposition of all or
substantially all of the Company's property, assets or business (except a
merger or other reorganization in which the Company shall be the surviving
corporation and holders of Common Shares receive no consideration in respect of
their shares) or (ii) any other transaction contemplated by Section 4.1(j)(ii)
above then, in any one or more of such cases, the Company shall cause to be
mailed to the Warrant Agent and shall cause the Warrant Agent to mail, at
Company's expense, to each Holder of a Warrant, at the earliest practicable
time (and, in any event, not less than 20 days before any date set for
definitive action), notice of the date on which such reorganization, sale,
consolidation, merger, dissolution, liquidation or winding up shall take place,
as the case may be.  Such notice shall also set forth such facts as shall
indicate the effect of such action (to the extent such effect may be known at
the date of such notice) on the Exercise Price and the kind and amount of the
Common Shares and other securities, money and other property deliverable upon
exercise of the Warrants.  Such notice shall also specify the date as of which
the holders of record of the Common Shares or other securities or property
issuable upon exercise of the Warrants shall be entitled to exchange their
shares for securities, money or other property deliverable upon such
reorganization, sale, consolidation, merger, dissolution, liquidation or
winding up, as the case may be.

                 Section 4.5.  Fractional Interests.  If more than one Warrant
shall be presented for exercise in full at the same time by the same Holder,
the number of full Common Shares which shall be issuable upon such exercise
thereof shall be computed on the basis of the aggregate number of Common Shares
purchasable on exercise of the Warrants so presented.  The Company shall not be
required to issue fractional Common Shares upon the exercise of Warrants.  If
any fraction of a Common Share would, except for the provisions of this Section
4.5, be issuable on the exercise of any Warrant (or specified portion thereof),
the Company may pay an amount in cash calculated by it to be equal to the then
Current Market Value per Common Share multiplied by such fraction computed to
the nearest whole cent.

                                       26


                 Section 4.6.  When Issuance or Payment May Be Deferred.  In
any case in which this Article IV shall require that an adjustment in the
Exercise Price be made effective as of a record date for a specified event, the
Company may elect to defer until the occurrence of such event (i) issuing to
the holder of any Warrant exercised after such record date the Common Shares
and other shares in the capital of the Company, if any, issuable upon such
exercise over and above the Common Shares and other shares in  the capital of
the Company, if any, issuable upon such exercise and (ii) paying such holder
any amount in cash in lieu of a fractional share; provided, however, that the
Company shall deliver to such Holder a due bill or other appropriate instrument
evidencing such Holder's right to receive such additional Common Shares, other
shares and cash upon the occurrence of the event requiring such adjustment.

                 Section 4.7.  Initial Public Offering.  Notwithstanding
anything to the contrary herein contained, if the Company conducts an initial
public offering of equity securities (other than nonconvertible preferred
shares), the Company will give the Holders the opportunity to convert such
Warrants into warrants to purchase such equity securities (other than
nonconvertible preferred shares) and such Common Shares or such other
securities that have been received by the Holders upon the exercise of Warrants
into such equity securities (other than nonconvertible preferred shares).  Such
conversion opportunity will be on terms and conditions determined to be fair
and reasonable by the Company's Board of Directors.

                                   ARTICLE V

                           DECREASE IN EXERCISE PRICE

                 The Board, in its sole discretion, shall have the right at any
time, or from time to time, to decrease the Exercise Price of the Warrants
and/or increase the number of shares issuable upon the exercise of the
Warrants.

                                   ARTICLE VI

                               LOSS OR MUTILATION

                 Upon receipt by the Company and the Warrant Agent of evidence
satisfactory to them of the ownership and the loss, theft, destruction or
mutilation of any Warrant Certificate and of indemnity or bond satisfactory to
them and (in the case of mutilation) upon surrender and cancellation thereof,
then, in the absence of notice to the Company or the Warrant Agent that the
Warrants represented thereby have been acquired by a bona fide purchaser, the
Company shall execute and the Warrant Agent shall countersign and deliver to
the registered Holder of the lost, stolen, destroyed or mutilated Warrant
Certificate, in
<PAGE>   31
                                       27


exchange for or in lieu thereof, a new Warrant Certificate of the same tenor
and for a like aggregate number of Warrants.  Upon the issuance of any new
Warrant Certificate under this Article VI, the Company may require the payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in relation thereto and other expenses (including the fees and expenses
of the Warrant Agent) in connection therewith.  Every new Warrant Certificate
executed and delivered pursuant to this Article VI in lieu of any lost, stolen
or destroyed Warrant Certificate shall constitute a contractual obligation of
the Company whether or not the allegedly lost, stolen or destroyed Warrant
Certificates shall be at any time enforceable by anyone and shall be entitled
to the benefits of this Agreement equally and proportionately with any and all
other Warrant Certificates duly executed and delivered hereunder.  The
provisions of this Article VI are exclusive and shall preclude (to the extent
lawful) all other rights or remedies with respect to the replacement of
mutilated, lost, stolen, or destroyed Warrant Certificates.

                                  ARTICLE VII

                         RESERVATION AND AUTHORIZATION
                                OF COMMON SHARES

                 The Company shall at all times reserve and keep available such
number of its authorized but unissued Common Shares deliverable upon exercise
of Warrants as will be sufficient to permit the exercise in full of all
outstanding Warrants and will cause appropriate evidence of ownership of such
Common Shares to be delivered to the Warrant Agent upon its request for
delivery thereof upon the exercise of Warrants.  The Company covenants that all
Common Shares of the Company that may be issued upon the exercise of the
Warrants will, upon issuance, be duly authorized, validly issued, fully paid
and not subject to any calls for funds and free from pre-emptive rights and all
taxes, liens, charges and security interests with respect to the issue thereof.

                                  ARTICLE VIII

                WARRANT TRANSFER BOOKS; RESTRICTIONS ON TRANSFER


                 Section 8.1.  Transfer and Exchange.  The Warrant Certificates
shall be issued in registered form only.  The Warrant Agent shall keep at its
office a register for the registration of Warrant Certificates and transfers or
exchanges of Warrant Certificates as herein provided and other appropriate data
as determined by the Warrant Agent.  The Company shall, upon reasonable notice
to the Warrant Agent, have access to such register during the Warrant Agent's
regular business hours.  All Warrant Certificates issued upon
<PAGE>   32
                                       28


any registration of transfer or exchange of Warrant Certificates shall be the
valid obligations of the Company, evidencing the same obligations, and entitled
to the same benefits under this Agreement, as the Warrant Certificates
surrendered for such registration of transfer or exchange.

                 The Warrants shall initially be issued as part of the issuance
of the Units.  Prior to the Separation Date, the Warrants may not be
transferred or exchanged separately from, but may be transferred or exchanged
only together with, the Notes issued as part of such Units.

                 A Holder may transfer its Warrants only by written application
to the Warrant Agent stating the name of the proposed transferee and otherwise
complying with the terms of this Agreement.  No such transfer shall be effected
until, and such transferee shall succeed to the rights of a Holder only upon,
final acceptance and registration of the transfer by the Warrant Agent in the
register.  Prior to the registration of any transfer of Warrants by a Holder as
provided herein, the Company, the Warrant Agent, and any agent of the Company
may treat the person in whose name the Warrants are registered as the owner
thereof for all purposes and as the person entitled to exercise the rights
represented thereby, any notice to the contrary notwithstanding.  Furthermore,
any holder of a Global Warrant shall, by acceptance of such Global Warrant,
agree that transfers of beneficial interests in such Global Warrant may be
effected only through a book-entry system maintained by the holder of such
Global Warrant (or its agent), and that ownership of a beneficial interest in
the Warrants represented thereby shall be required to be reflected in a
book-entry.  When Warrant Certificates are presented to the Warrant Agent with
a request to register the transfer or to exchange them for an equal amount of
Warrants of other authorized denominations, the Warrant Agent shall register
such transfer or make such exchange as requested if its requirements for such
transactions are met.  To permit registrations of transfers and exchanges, the
Company shall execute Warrant Certificates at the Warrant Agent's request.  No
service charge shall be made for any registration of transfer or exchange of
Warrants, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge that may be imposed in connection with any
registration of transfer of Warrants.

                 Section 8.2.  Book-Entry Provisions for the Global Warrants.
(a)  The Global Warrants initially shall (i) be registered in the name of the
Depositary for such Global Warrant or the nominee of such Depositary, (ii) be
delivered to the Warrant Agent as custodian for such Depositary and (iii) bear
legends as set forth in Section 2.2 hereof.

                 Members of, or participants in, the Depositary ("Agent
Members") shall have no rights under this Agreement with respect to the Global
Warrants held on their behalf by the Depositary or the Warrant Agent as its
custodian, and the Depositary may be treated by the Company, the Warrant Agent
and any agent of the Company or the Warrant Agent as the
<PAGE>   33
                                       29


absolute owner of such Global Warrant for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the Company, the
Warrant Agent or any agent of the Company or the Warrant Agent, from giving
effect to any written certification, proxy or other authorization furnished by
the Depositary or impair, as between the Depositary and its Agent Members, the
operation of customary practices governing the exercise of the rights of a
Holder of any Warrants.

                 (b)      Transfers of a Global Warrant shall be limited to
transfers of such Global Warrant in whole, but not in part, to the Depositary,
its successors or their respective nominees.  Interests of beneficial owners in
the Global Warrants may be transferred in accordance with the rules and
procedures of the Depositary and the provisions of Section 8.3 hereof.  U.S.
Certificated Warrants and Offshore Certificated Warrants shall be transferred
to beneficial owners in exchange for their beneficial interests in the
Restricted Global Warrant or the Regulation S Global Warrant, as the case may
be, (i) if the Depositary notifies the Company that it is unwilling or unable
to continue as Depositary for any such Global Warrant and a successor
depositary is not appointed by the Company within 90 days of such notice, (ii)
if there is a Default or (iii) upon the request of the beneficial owner in
accordance with the rules and procedures of the Depositary and the provisions
of Section 8.3 hereof; provided that Offshore Certificated Warrants shall not
be transferred in exchange for the Legended Regulation S Global Note prior to
one year after the Closing Date.

                 (c)      Any beneficial interest in one of the Global Warrants
that is transferred to a person who takes delivery in the form of an interest
in any other Global Warrant will, upon transfer, cease to be an interest in
such Global Warrant and become an interest in such other Global Warrant and,
accordingly, will thereafter be subject to all transfer restrictions, if any,
and other procedures applicable to beneficial interests in such other Global
Warrant for as long as it remains such an interest.

                 (d)      In connection with the transfer of the entire
Restricted Global Warrant or Regulation S Global Warrant to beneficial owners
pursuant to paragraph (b) of this Section 8.2, the Restricted Global Warrant or
the Regulation S Global Warrant, as the case may be, shall be surrendered to
the Warrant Agent for cancellation, and the Company shall execute, and the
Warrant Agent shall countersign and deliver, to each beneficial owner
identified by the Depositary in exchange for its beneficial interest in the
Restricted Global Warrant or the Regulation S Global Warrant, as the case may
be, U.S. Certificated Warrants or Offshore Certificated Warrants, as the case
may be, of authorized denominations representing, in the aggregate, the number
of Warrants theretofore represented by the Restricted Global Warrant or the
Regulation S Global Warrant, as the case may be.

                 (e)      In connection with the transfer of a portion of the
beneficial interests in the Restricted Global Warrant or the Unlegended
Regulation S Global Warrant to beneficial owners pursuant to paragraph (b) of

books and records the date and a decrease in the amount of Warrants represented
by the Restricted Global Warrant or Unlegended Regulation S Global Warrant in
an amount equal to the amount of Warrants represented by the beneficial
interest in the Restricted Global Warrant or Unlegended Regulation S Global
Warrant to be transferred, and the Company shall execute, and the Warrant Agent
shall countersign and deliver, to each beneficial owner identified by the
Depositary in exchange for its beneficial interest in the Restricted Global
Warrant or the Unlegended Regulation S Global Warrant, as the case may be, U.S.
Certificated Warrants or Offshore Certificated Warrants, as the case may be, of
like tenor and amount.

                 (f)      Any Certificated Warrant delivered in exchange for an
interest in a Global Warrant pursuant to paragraph (b), (d) or (e) of this
Section shall, except as otherwise provided by paragraph (d) of Section 8.3

                 (g)      The registered holder of a Global Warrant may grant

         Certificated Warrants or by an interest in the Regulation S Global
         Warrant, the Warrant Agent shall register the transfer if such
         transfer is being made by a proposed transferor who has checked the
         box provided for on the form of Warrant Certificate stating, or has
         otherwise advised the Company and the Warrant Agent in writing, that
         the sale has been made in compliance with the provisions of Rule 144A
         to a transferee who has signed the certification provided for on the
         form of Warrant Certificate stating, or has otherwise advised the
         Company and the Warrant Agent in writing, that it is purchasing the
         Warrants for its own account or an account with respect to which it
         exercises sole investment discretion and that it and any such account
         is a QIB within the meaning of Rule 144A, and is aware that the sale
         to it is being made in reliance on Rule 144A and acknowledges that it
         has received such information regarding the Company as it has
         requested pursuant to Rule 144A or has determined not to request such
         information and that it is aware that the transferor is relying upon

<PAGE>   35
                                       31


         representations in order to claim the exemption from registration
         provided by Rule 144A.

                 (ii)     If the proposed transferee is an Agent Member, and

         Warrants or an interest in the Regulation S Global Warrant, upon
         receipt by the Warrant Agent of the documents referred to in clause
         (i) above and instructions given in accordance with the Depositary's
         and the Warrant Agent's procedures, the Warrant Agent shall reflect on
         its books and records the date and an increase in the amount of
         Warrants represented by the Restricted Global Warrant in an amount
         equal to the amount of Warrants represented by the Certificated
         Warrants or the interest in the Regulation S Global Warrant, as the
         case may be, to be transferred, and the Warrant Agent shall cancel the
         Certificated Warrants or decrease the amount of the Regulation S
         Global Warrant so transferred.

                 (b)      Transfers to Non-U.S. Persons at Any Time.  The
following provisions shall apply with respect to the registration of any
proposed transfer of Warrants to a Non-U.S. Person:

                 (i)      The Warrant Agent shall register any proposed
         transfer of Warrants to a Non-U.S. Person only upon receipt of a
         certificate substantially in the form of Exhibit B from the proposed
         transferor.

                 (ii)     If the proposed transferee is an Agent Member and the
         Warrants to be transferred are represented by Certificated Warrants or
         an interest in the Restricted Global Warrant, upon receipt by the
         Warrant Agent of the documents referred to in clause (i) above and
         instructions given in accordance with the Depositary's and the Warrant
         Agent's procedures, the Warrant Agent shall reflect on its books and
         records the date and an increase in the number of Warrants represented
         by the Regulation S Global Warrant in an amount equal to the number of
         Warrants represented by the Certificated Warrants or the Restricted
         Global Warrant, as the case may be, to be transferred, and the Warrant
         Agent shall cancel the Certificated Warrant or decrease the amount of
         Warrants represented by the Restricted Global Warrant so transferred.

                 (c)      Transfers to Any Other Person.  The following

                 (i)      The Warrant Agent shall register any proposed
         transfer of Warrants to any such Person if (x) the transferor has
         delivered to the Warrant Agent and the Company a certificate

         paragraph (d) thereof, an Opinion of Counsel to the effect set forth
         therein and
<PAGE>   36
                                       32


         (y) the proposed transferee has delivered to the Warrant Agent and the
         Company a certificate substantially in the form of Exhibit C-2 hereto
         if such transferee is an Institutional Accredited Investor that is not
         a QIB.

                 (ii)     If the proposed transferor is an Agent Member holding
         a beneficial interest in the Restricted Global Warrant or the
         Regulation S Global Warrant, upon receipt by the Warrant Agent and the
         Company of the documents referred to in clause (i) above and
         instructions given in accordance with the Depositary's and the Warrant
         Agent's procedures, the Company shall execute and the Warrant Agent
         shall countersign Certificated Warrants in an amount equal to the
         number of Warrants represented by the Restricted Global Warrant or the
         Regulation S Global Warrant, if any, as the case may be, to be
         transferred and the Warrant Agent shall decrease the number of
         Warrants represented by the Restricted Global Warrant or the
         Regulation S Global Warrant so transferred.

                 (d)      Private Placement Legend.  Upon the transfer,
exchange or replacement of Warrant Certificates not bearing the Private
Placement Legend, the Warrant Agent shall deliver Warrant Certificates that do
not bear the Private Placement Legend.  Upon the transfer, exchange or
replacement of Warrant Certificates bearing the Private Placement Legend, the
Warrant Agent shall deliver only Warrant Certificates that bear the Private
Placement Legend unless either (i) the circumstances contemplated by the third
sentence of the third paragraph of Section 2.1 exist or (ii) there is delivered
to the Warrant Agent an opinion of counsel reasonably satisfactory to the
Company and its Counsel and the Warrant Agent to the effect that neither such
legend nor the related restrictions on transfer are required in order to
maintain compliance with the provisions of the Securities Act.

                 (e)      Transfers of Interests in the Legended Regulation S
Global Warrant.  The following provisions shall apply with respect to
registration of any proposed transfer of interests in the Legended Regulation S
Global Warrant:

                 (i)      The Registrar shall register the transfer of any
         Warrant (x) if the proposed transferee is a Non-U.S. Person and the
         proposed transferor has delivered to the Registrar a certificate
         substantially in the form of Exhibit B hereto or (y) if the proposed
         transferee is a QIB and the proposed transferor has checked the box
         provided for on the form of Warrant stating, or has otherwise advised
         the Company and the Warrant Agent in writing, that the sale has been
         made in compliance with the provisions of Rule 144A to a transferee
         who has signed the certification provided for on the form of Warrant
         stating, or has otherwise advised the Company and the Warrant Agent in
         writing, that it is purchasing the Warrant for its own account or an
         account with respect to which it exercises sole investment discretion
         and that it and any such account is a QIB within the meaning of Rule
         144A, and is aware that the sale to it is being made in reliance on
         Rule 144A and acknowledges that it has
<PAGE>   37
                                       33


         received such information regarding the Company as it has requested
         pursuant to Rule 144A or has determined not to request such
         information and that it is aware that the transferor is relying upon
         its foregoing representations in order to claim the exemption from
         registration provided by Rule 144A.

                 (ii)     If the proposed transferee is an Agent Member, upon
         receipt by the Warrant Agent of the documents referred to in clause
         (i)(y) above and instructions given in accordance with the
         Depositary's and the Warrant Agent's procedures, the Warrant Agent
         shall reflect on its books and records the date and an increase in the
         number of Warrants represented by the Restricted Global Warrant, in an
         amount equal to the number of Warrants represented by the Legended
         Regulation S Global Warrant to be transferred, and the Warrant Agent
         shall decrease the number of Warrants represented by the Legended
         Regulation S Global Warrant.

                 (f)      Transfers of Interests in the Unlegended Regulation S
Global Note or Unlegended Offshore Certificated Warrants.  The following
provisions shall apply with respect to any transfer of interests in the
Unlegended Regulation S Global Warrant or unlegended Offshore Certificated
Warrants:  The Warrant Agent shall register the transfer of any such Warrant
without requiring any additional certification.

                 (g)      General.  (i)  By its acceptance of any Warrants
represented by a Warrant Certificate bearing the Private Placement Legend, each
Holder of such Warrants acknowledges the restrictions on transfer of such
Warrants set forth in this Agreement and in the Private Placement Legend and
agrees that it will transfer such Warrants only as provided in this Agreement.
The Warrant Agent shall not register a transfer of any Warrants unless such
transfer complies with the restrictions on transfer of such Warrants set forth
in this Agreement.  In connection with any transfer of Warrants, each Holder
agrees by its acceptance of Warrants to furnish the Warrant Agent or the
Company such certifications, legal opinions or other information as either of
them may reasonably require to confirm that such transfer is being made
pursuant to an exemption from, or a transaction not subject to, the
registration requirements of the Securities Act; provided that the Warrant
Agent shall not be required to determine (but may rely on a determination made
by the Company with respect to) the sufficiency of any such certifications,
legal opinions or other information.

                 (ii)     The Warrant Agent shall retain copies of all letters,
         notices and other written communications received pursuant to Section
         8.2 hereof or this Section 8.3.  The Company shall have the right to
         inspect and make copies of all such letters, notices or other written
         communications at any reasonable time upon the giving of reasonable
         written notice to the Warrant Agent.

                 Section 8.4.  Surrender of Warrant Certificates.  Any Warrant
Certificate surrendered for registration of transfer, exchange or exercise of
the Warrants represented
<PAGE>   38
                                       34


thereby shall, if surrendered to the Company, be delivered to the Warrant
Agent, and all Warrant Certificates surrendered or so delivered to the Warrant
Agent shall be promptly cancelled by the Warrant Agent and shall not be
reissued by the Company and, except as provided in this Article VIII in case of
an exchange, Article III hereof in case of the exercise of less than all the
Warrants represented thereby or Article VI in case of a mutilated Warrant
Certificate, no Warrant Certificate shall be issued hereunder in lieu thereof.
The Warrant Agent shall deliver to the Company from time to time or otherwise
dispose of such cancelled Warrant Certificates as the Company may direct in
writing.


                                   ARTICLE IX

                                WARRANT HOLDERS

                 Section 9.1.  Warrant Holder Deemed Not a Shareholder.  The
Company and the Warrant Agent may deem and treat the registered Holder(s) of
the Warrant Certificates as the absolute owner(s) thereof (notwithstanding any
notation of ownership or other writing thereon made by anyone), for the purpose
of any exercise thereof and for all other purposes, and neither the Company nor
the Warrant Agent shall be affected by any notice to the contrary.
Accordingly, the Company and/or the Warrant Agent shall not, except as ordered
by a court of competent jurisdiction as required by law, be bound to recognize
any equitable or other claim to or interest in the Warrants on the part of any
person other than such registered Holder, whether or not it shall have express
or other notice thereof.  Prior to the exercise of the Warrants, no Holder of a
Warrant Certificate, as such, shall be entitled to any rights of a shareholder
of the Company, including, without limitation, the right to vote or to consent
to any action of the shareholders, to receive dividends or other distributions,
to exercise any preemptive right or to receive any notice of meetings of
shareholders and, except as otherwise provided in this Agreement, shall not be
entitled to receive any notice of any proceedings of the Company.

                 Section 9.2.  Right of Action.  All rights of action with
respect to this Agreement are vested in the Holders of the Warrants, and any
Holder of any Warrant, without the consent of the Warrant Agent or the Holders
of any other Warrant, may, on such Holder's own behalf and for such Holder's
own benefit, enforce, and may institute and maintain any suit, action or
proceeding against the Company suitable to enforce, or otherwise in respect of,
such Holder's right to exercise such Warrants in the manner provided in the
Warrant Certificate representing such Warrants and in this Agreement.

                                    REMEDIES

                 Section 10.1.  Defaults.  It shall be deemed to be a "Default"
with respect to the Company's (or its successor's) obligations under this
Agreement if:

                 (a)      a Repurchase Event occurs and the Company (or its
         successor) shall fail to make a Repurchase Offer pursuant to Section
         3.4 hereof; or

                 (b)      the Company (or its successor) shall fail to purchase
         the Warrants pursuant to the Repurchase Offer in accordance with the
         provisions of Section 3.4 hereof.

                 Section 10.2.  Payment Obligations.  Upon the happening of a
Default under this Agreement, the Company shall be obligated to increase the
amount otherwise payable pursuant to Section 3.4(d) hereof in respect of the
Repurchase Offer to which such Default relates by an amount equal to interest
thereon at a rate per annum equal to 13% from the date of the Default to the
date of payment, which interest shall compound quarterly (all such payment
obligations in respect of such Repurchase Offer, together with all such
increased amounts, being the "Repurchase Obligation").

                 Section 10.3.  Remedies; No Waiver.  Notwithstanding any other
provision of this Warrant Agreement, if a Default occurs and is continuing, the
Holders of the Warrants may pursue any available remedy to collect the
Repurchase Obligation or to enforce the performance of any provision of this
Warrant Agreement.  A delay or omission by any Holder of a Warrant in
exercising, or a failure to exercise, any right or remedy arising out of a
Default shall not impair the right or remedy or constitute a waiver of or
acquiescence in the Default. All remedies are cumulative to the extent
permitted by law.

                                   ARTICLE XI

                               THE WARRANT AGENT

                 Section 11.1.  Duties and Liabilities.  The Warrant Agent
hereby accepts the agency established by this Agreement and agrees to perform
the same upon the terms and conditions herein set forth, by all of which the
Company and the Holders of Warrants, by their acceptance thereof, shall be
bound.  The Warrant Agent shall not, by countersigning Warrant Certificates or
by any other act hereunder, be deemed to make any representations as to the
validity or authorization of the Warrants or the Warrant Certificates (except
as to its countersignature thereon) or of any Common Shares issued upon
exercise of any Warrant, or as to the accuracy of the computation of the
Exercise Price or the number or kind or amount of Common Shares deliverable
upon exercise of any Warrant or the correctness of
<PAGE>   40
                                       36


the representations of the Company made in the certificates that the Warrant
Agent receives.  The Warrant Agent shall not be accountable for the use or
application by the Company of the proceeds of the exercise of any Warrant.  The
Warrant Agent shall not have any duty to calculate or determine any adjustments
with respect to either the Exercise Price or the kind and amount of Common
Shares receivable by Holders upon the exercise of Warrants required from time
to time and the Warrant Agent shall have no duty or responsibility in
determining the accuracy or correctness of such calculation.  The Warrant Agent
shall not be (a) liable for any recital or statement of fact contained herein
or in the Warrant Certificates or for any action taken, suffered or omitted by
it in good faith in the belief that any Warrant Certificate or any other
documents or any signatures are genuine or properly authorized, (b) responsible
for any failure on the part of the Company to comply with any of its covenants
and obligations contained in this Agreement or in the Warrant Certificates or
(c) liable for any act or omission in connection with this Agreement except for
its own gross negligence, bad faith or willful misconduct.  The Warrant Agent
is hereby authorized to accept instructions with respect to the performance of
its duties hereunder from the Chairman of the Board, Chief Executive Officer,
any Vice President or other executive officer of the Company and to apply to
any such officer for instructions (which instructions will be promptly given in
writing when requested) and the Warrant Agent shall not be liable for any
action taken or suffered to be taken by it in good faith in accordance with the
instructions of any such officer; however, in its discretion, the Warrant Agent
may, in lieu thereof, accept other evidence of such or may require such further
or additional evidence as it may deem reasonable.  The Warrant Agent shall not
be liable for any action taken with respect to any matter in the event it
requests instructions from the Company as to that matter and does not receive
such instructions within a reasonable period of time after the request
therefor.

                 The Warrant Agent may execute and exercise any of the rights
and powers hereby vested in it or perform any duty hereunder either itself or
by or through its attorneys, agents or employees, and the Warrant Agent shall
not be answerable or accountable for any act, default, neglect or misconduct of
any such attorneys, agents or employees; provided reasonable care has been
exercised with respect to the retention of any such attorney, agent or
employee.  The Warrant Agent shall not be under any obligation or duty to
institute, appear in or defend any action, suit or legal proceeding in respect
hereof, unless first indemnified to its reasonable  satisfaction.  The Warrant
Agent shall promptly notify the Company in writing of any claim made or action,
suit or proceeding instituted against it arising out of or in connection with
this Agreement.

                 The Company will perform, execute, acknowledge and deliver or
cause to be delivered all such further acts, instruments and assurances as are
consistent with this Agreement and as may reasonably be required by the Warrant
Agent in order to enable it to carry out or perform its duties under this
Agreement.
<PAGE>   41
                                       37


                 The Warrant Agent shall act solely as agent of the Company
hereunder.  The Warrant Agent shall not be liable except for the failure to
perform such duties as are specifically set forth herein, and no implied
covenants or obligations shall be read into this Agreement against the Warrant
Agent, whose duties and obligations shall be determined solely by the express
provisions hereof.

                 Section 11.2.  Right to Consult Counsel.  The Warrant Agent
may at any time consult with legal counsel (who may be legal counsel for the
Company), and the opinion or advice of such counsel shall be full and complete
authorization and protection to the Warrant Agent and the Warrant Agent shall
incur no liability or responsibility to the Company or to any Holder for any
action taken, suffered or omitted by it in good faith in accordance with the
opinion or advice of such counsel.

                 Section 11.3.  Compensation; Indemnification.  The Company
agrees promptly to pay the Warrant Agent from time to time and in any case
within 30 days of receipt of an invoice, compensation for its services
hereunder as the Company and the Warrant Agent may agree from time to time, and
to reimburse it upon its request for reasonable fees or expenses and reasonable
counsel fees and expenses incurred in connection with the execution and
administration of this Agreement, and further agrees to indemnify the Warrant
Agent and save it harmless against any losses, liabilities or expenses arising
out of or in connection with the acceptance and administration of this
Agreement, including, without limitation, the reasonable costs and expenses of
investigating or defending any claim of such liability, except that the Company
shall have no liability hereunder to the extent that any such loss, liability
or expense results from the Warrant Agent's own gross negligence, bad faith or
willful misconduct.  The obligations of the Company under this Section 11.3
shall survive the exercise and the expiration of the Warrants, the termination
of this Agreement and the resignation or removal of the Warrant Agent in
respect of services or expenses incurred in connection with the Warrants or
this Agreement.

                 Section 11.4.  No Restrictions on Actions.  Nothing in this
Agreement shall be deemed to prevent the Warrant Agent and any shareholder,
director, officer or employee of the Warrant Agent from buying, selling or
dealing in any of the Warrants or other securities of the Company or becoming
pecuniarily interested in transactions in which the Company may be interested,
or contracting with or lending money to the Company or otherwise acting as
fully and freely as though it were not the Warrant Agent under this Agreement.
Nothing herein shall preclude the Warrant Agent from acting in any other
capacity for the Company or for any other legal entity.

                 Section 11.5.  Discharge or Removal; Replacement Warrant
Agent.  The Warrant Agent may resign from its position as such and be
discharged from all further duties and liabilities hereunder (except liability
arising as a result of the Warrant Agent's own gross negligence, bad faith or
willful misconduct), after giving one month's prior written notice to
<PAGE>   42
                                       38


the Company.  The Company may at any time remove the Warrant Agent upon one
month's written notice specifying the date when such discharge shall take
effect, and the Warrant Agent shall thereupon in like manner be discharged from
all further duties and liabilities hereunder, except as aforesaid.  The Warrant
Agent shall mail to each Holder of a Warrant, at the Company's expense, a copy
of said notice of resignation or notice of removal, as the case may be.  Upon
such resignation or removal the Company shall appoint in writing a new warrant
agent.  If the Company shall fail to make such appointment within a period of
30 days after it has been notified in writing of such resignation by the
resigning Warrant Agent or after such removal, then the resigning or removed
Warrant Agent or the Holder of any Warrant may apply to any court of competent
jurisdiction for the appointment of a new warrant agent.  After 30 days from
receipt of, or giving, notice, as the case may be, and pending appointment of a
successor to the original Warrant Agent, either by the Company or by such a
court, the duties of the Warrant Agent shall be carried out by the Company.
Any new warrant agent, whether appointed by the Company or by such a court,
shall be a bank or trust company doing business under the laws of the United
States or any state thereof, in good standing and having a combined capital and
surplus of not less than $25,000,000.  The combined capital and surplus of any
such new warrant agent shall be deemed to be the combined capital and surplus
as set forth in the most recent annual report of its condition published by
such warrant agent prior to its appointment, provided that such reports are
published at least annually pursuant to law or to the requirements of a federal
or state supervising or examining authority.  After acceptance in writing of
such appointment by the new warrant agent, it shall be vested with the same
powers, rights, duties and responsibilities as if it had been originally named
herein as the Warrant Agent, without any further assurance, conveyance, act or
deed; however, the original Warrant Agent shall in all events deliver and
transfer to the successor Warrant Agent all property (including, without
limitation, documents and recorded information), if any, at the time held
hereunder by the original Warrant Agent and if for any reason it shall be
necessary or expedient to execute and deliver any further assurance,
conveyance, act or deed, the same shall be done at the expense of the Company
and shall be legally and validly executed and delivered by the resigning or
removed Warrant Agent.  Not later than the effective date of any such
appointment, the Company shall file notice thereof with the resigning or
removed Warrant Agent and shall forthwith cause a copy of such notice to be
mailed by the successor Warrant Agent to each Holder of a Warrant.  Failure to
give any notice provided for in this Section 11.5, however, or any defect
therein, shall not affect the legality or validity of the resignation of the
Warrant Agent or the appointment of a new warrant agent, as the case may be.
No Warrant Agent hereunder shall be liable for any acts or omissions of any
successor Warrant Agent.

                 Section 11.6.  Successor Warrant Agent.  Any corporation into
which the Warrant Agent or any new warrant agent may be merged or converted, or
any corporation resulting from any consolidation to which the Warrant Agent or

                                 MISCELLANEOUS

                 Section 12.1.  Monies Deposited with the Warrant Agent.  The
Warrant Agent shall not be required to pay interest on any monies deposited
pursuant to the provisions of this Agreement except such as it shall agree in
writing with the Company to pay thereon.  Any monies, securities or other
property which at any time shall be deposited by the Company or on its behalf
with the Warrant Agent pursuant to this Agreement shall be and are hereby
assigned, transferred and set over to the Warrant Agent in trust for the
purpose for which such monies, securities or other property shall have been
deposited; but such monies, securities or other property need not be segregated
from other funds, securities or other property except to the extent required by
law.  Any monies, securities or other property deposited with the Warrant Agent
for payment or distribution to the Holders that remains unclaimed for one year
after the date the monies, securities or other property was deposited with the
Warrant Agent shall be delivered to the Company upon its request therefor.

                 Section 12.2.  Payment of Taxes.  Subject to Article VI
hereof, all Common Shares issuable upon the exercise of Warrants shall be
validly issued, fully paid and not subject to any calls for funds, and the
Company shall pay any taxes and other governmental charges that may be imposed
under the laws of the United States of America or any political subdivision or
taxing authority thereof or therein in respect of the issue or delivery thereof
upon exercise of Warrants (other than income taxes imposed on the Holders).
The Company shall not be required, however, to pay any tax or other charge
imposed in connection with any transfer involved in the issue of any
certificate for Common Shares (including other securities or property issuable
upon the exercise of the Warrants) or payment of cash to any Person other than
the Holder of a Warrant Certificate surrendered upon the exercise of a Warrant
and in case of such transfer or payment, the Warrant Agent and the Company
shall not be required to issue any share certificate or pay any cash until such
tax or charge has been paid or it has been established to the Warrant Agent's
and the Company's satisfaction that no such tax or charge is due.

                 Section 12.3.  No Merger, Consolidation or Sale of Assets of
the Company.  Except as otherwise provided herein, the Company will not merge
into or consolidate with
<PAGE>   44
                                       40


any other Person, or sell or otherwise transfer its property, assets and
business substantially as an entirety to a successor of the Company, unless the
Person resulting from such merger or consolidation, or such successor of the
Company, shall expressly assume, by supplemental agreement satisfactory in form
to the Warrant Agent and executed and delivered to the Warrant Agent, the due
and punctual performance and observance of each and every covenant and
condition of this Agreement or contained in the Warrants to be performed and
observed by the Company.

                 Section 12.4.  Reports to Holders.  At all times from and
after the earlier of (i) the Separation Date and (ii) September 6, 1997, in
either case, whether or not the Company is then required to file reports with
the Commission, the Company shall file with the Commission all such reports and
other information it would be required to file with the Commission by Section
13(a) or 15(d) under the Exchange Act if it were subject thereto.  The Company
shall supply the Warrant Agent and each Holder or shall supply to the Warrant
Agent for forwarding to each such Holder, without cost to such Holder, copies
of such reports and other information.  The Warrant Agent's receipt of such
reports and other information shall not constitute constructive notice of any
information contained therein or determinable from information contained
therein, including the Company's compliance with any of its covenants hereunder
(as to which the Warrant Agent is entitled to rely exclusively on Officers'
Certificates).  In addition, at all times prior to the earlier of the
Separation Date and September 6, 1997, the Company shall, at its cost, deliver
to each Holder quarterly and annual reports substantially equivalent to those
which would be required by the Exchange Act.  In addition, at all times, upon
the request of any Holder or any prospective purchaser of the Warrants
designated by a Holder, the Company shall supply to such Holder or such
prospective purchaser the information required under Rule 144A under the
Securities Act.

                 Section 12.10.  Common Shares Legend.  Unless and until the
Common Shares issuable upon the exercise of the Warrants are registered under
the Securities Act, or unless otherwise agreed by the Company and the Holder
thereof, such Common Shares will bear a legend to the following effect:

         THE COMMON SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
         REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE
         "SECURITIES ACT"), AND ACCORDINGLY, MAY NOT BE OFFERED, SOLD, PLEDGED
         OR OTHERWISE TRANSFERRED WITHIN THE UNITED STATES OR TO, OR FOR THE
         ACCOUNT OR BENEFIT OF, U.S. PERSONS EXCEPT AS SET FORTH IN THE
         FOLLOWING SENTENCE.  BY ITS ACQUISITION HEREOF, THE HOLDER (1)
         REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL BUYER" (AS
         DEFINED IN RULE 144A UNDER THE SECURITIES ACT) OR (B) IT IS AN
         INSTITUTIONAL "ACCREDITED INVESTOR" (AS DEFINED IN RULE 501(a)(1),
         (2), (3) OR (7) OF REGULATION D UNDER THE SECURITIES ACT) (AN
         "INSTITUTIONAL ACCREDITED INVESTOR") OR (C) IT IS NOT A U.S. PERSON
         AND IS ACQUIRING THE COMMON SHARES REPRESENTED BY THIS CERTIFICATE IN
         AN OFFSHORE TRANSACTION IN COMPLIANCE WITH REGULATION S UNDER THE
         SECURITIES ACT, (2) AGREES THAT IT WILL NOT, WITHIN THE TIME PERIOD
         REFERRED TO UNDER RULE 144(k) TAKING INTO ACCOUNT THE PROVISIONS OF
         RULE 144(d), IF APPLICABLE, UNDER THE SECURITIES ACT AS IN EFFECT WITH
         RESPECT TO SUCH TRANSFER, RESELL OR OTHERWISE TRANSFER THE COMMON
         SHARES REPRESENTED BY THIS CERTIFICATE EXCEPT (A) TO MCCAW
         INTERNATIONAL, LTD. (THE "COMPANY") OR ANY SUBSIDIARY THEREOF, (B) TO
         A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE
         SECURITIES ACT, (C) INSIDE THE UNITED STATES TO AN INSTITUTIONAL

<PAGE>   47
                                       43


         FURNISHES TO THE TRANSFER AGENT AND REGISTRAR A SIGNED LETTER
         CONTAINING CERTAIN REPRESENTATIONS AND AGREEMENTS RELATING TO THE
         RESTRICTIONS ON TRANSFER OF THE COMMON SHARES REPRESENTED BY THIS
         CERTIFICATE (THE FORM OF WHICH LETTER CAN BE OBTAINED FROM THE
         TRANSFER AGENT AND REGISTRAR) AND AN OPINION OF COUNSEL ACCEPTABLE TO
         THE COMPANY THAT SUCH TRANSFER IS IN COMPLIANCE WITH THE SECURITIES
         ACT, (D) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN
         COMPLIANCE WITH RULE 904 UNDER THE SECURITIES ACT, (E) PURSUANT TO THE
         EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES
         ACT (IF AVAILABLE) OR (F) PURSUANT TO AN EFFECTIVE REGISTRATION
         STATEMENT UNDER THE SECURITIES ACT AND (3) AGREES THAT IT WILL DELIVER
         TO EACH PERSON TO WHOM THE COMMON SHARES REPRESENTED BY THIS
         CERTIFICATE ARE TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF
         THIS LEGEND.  IN CONNECTION WITH ANY TRANSFER OF THE COMMON SHARES
         REPRESENTED BY THIS CERTIFICATE WITHIN THE TIME PERIOD REFERRED TO
         ABOVE, THE HOLDER MUST CHECK THE APPROPRIATE BOX SET FORTH ON THE
         REVERSE HEREOF RELATING TO THE MANNER OF SUCH TRANSFER AND SUBMIT THIS
         CERTIFICATE TO THE TRANSFER AGENT AND REGISTRAR.  IF THE PROPOSED
         TRANSFEREE IS AN INSTITUTIONAL ACCREDITED INVESTOR, THE HOLDER MUST,
         PRIOR TO SUCH TRANSFER, FURNISH TO EACH OF THE TRANSFER AGENT AND
         REGISTRAR AND THE COMPANY SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER
         INFORMATION AS EITHER OF THEM MAY REASONABLY REQUIRE TO CONFIRM THAT
         SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A
         TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE
         SECURITIES ACT.  AS USED HEREIN, THE TERMS "OFFSHORE TRANSACTION,"
         "UNITED STATES" AND "U.S. PERSON" HAVE THE MEANINGS GIVEN TO THEM BY
         REGULATION S UNDER THE SECURITIES ACT.  THE WARRANT AGREEMENT CONTAINS
         A PROVISION REQUIRING THE TRANSFER AGENT AND REGISTRAR TO REFUSE TO
         REGISTER ANY TRANSFER OF THE SHARES OF COMMON STOCK REPRESENTED BY
         THIS CERTIFICATE IN VIOLATION OF THE FOREGOING RESTRICTIONS.

                 Section 12.11.  Third Party Beneficiaries.  The Holders shall

Company, on the one hand, and
<PAGE>   48
                                       44


the Warrant Agent, on the other hand, and each Holder shall have the right to
enforce such agreements directly to the extent it deems such enforcement
necessary or advisable to protect its rights or the rights of Holders
hereunder.  By acquiring Warrants, each Holder agrees to be bound by the
obligations of Holders generally as set forth herein and as such obligations
may be applicable to such Holder.

                 Section 12.12.  Termination.  Except as otherwise specified
herein, this Agreement shall terminate at 5:00 p.m. (New York City time) on the
tenth anniversary of the Closing Date.  Notwithstanding the foregoing, this
Agreement shall terminate on any earlier date as of which all Warrants have
been exercised.

                 Section 12.13.  Right of First Opportunity Agreement.  The
Company agrees not to amend the Right of First Opportunity Agreement in any
respect material and adverse to the Holders of the Warrants.  If the Company
proposes to amend the Right of First Opportunity Agreement, it shall notify the
Warrant Agent in writing 30 days prior to the effectiveness of such amendment
of such proposal to amend and such notice shall include a written copy of the
contents of such proposed amendment (the "Right of First Opportunity Notice").

         Within five days of receipt of a Right of First Opportunity Notice,
the Warrant Agent shall give written notice to the Holders of the Right of
First Opportunity Notice.  Such notice by the Warrant Agent shall include a
copy of the Right of First Opportunity Notice.

be duly executed, as of the day and year first above written.

                       WARRANTS TO PURCHASE COMMON SHARES

                 This certifies that ______________, or its registered assigns,
is the owner of ___________ Warrants, each of which represents the right to
purchase, after March 6, 1998, from MCCAW INTERNATIONAL, LTD., a Washington
corporation (the "Company"), 0.10616 common shares, without par value, of the
Company (the "Common Shares") at an exercise price (the "Exercise Price") of
$36.45 per Common Share (subject to adjustment as provided in the Warrant
Agreement hereinafter referred to below), upon surrender hereof at the office
of The Bank of New York, or to its successor, as the warrant agent under the
Warrant Agreement (any such warrant agent being herein called the "Warrant
Agent"), with the Subscription Form on the reverse hereof duly executed, with
signature guaranteed as therein specified and simultaneous payment in full by
wire transfer or by certified or official bank or bank cashier's check payable
to the order of the Company.  Notwithstanding the foregoing, if the Common
Shares (or other securities) issuable upon exercise of the Warrants are
registered under the Exchange Act, the Exercise Price may be paid by
surrendering additional Warrants to the Warrant Agent having an aggregate
Spread equal to the aggregate Exercise Price of the Warrants being exercised.
At any time after one year after the Closing Date and on or before the
Expiration Date, any outstanding Warrants may be exercised on any Business Day;
provided that the Warrant Registration Statement is, at the time of exercise,
effective and available for the exercise of Warrants or the exercise of such
Warrants is exempt from the registration requirements of the Securities Act.

                 This Warrant Certificate is issued under and in accordance
with a Warrant Agreement dated as of March 6, 1997 (the "Warrant Agreement"),
between the Company and The Bank of New York and a Registration Rights
Agreement dated as of March 3, 1997 (the "Warrant Registration Rights
Agreement"), between the Company and The Bank of New York, as Warrant Agent,
and is subject to the Articles of Incorporation and Bylaws of the Company and
to the terms and provisions contained therein, to all of which terms and
provisions the Holder of this Warrant Certificate consents by acceptance
hereof.  The terms of the Warrant Agreement  and the Warrant Registration
Rights Agreement are hereby incorporated herein by reference and made a part
hereof.  Reference is hereby made to the Warrant Agreement and the Warrant
Registration Rights Agreement for a full description of the rights, limitations
of rights, obligations, duties and immunities thereunder of the Company and the
Holders of the Warrants.  The summary of the terms of the Warrant
<PAGE>   51
                                      A-2


Agreement and the Warrant Registration Rights Agreement contained in this
Warrant Certificate is qualified in its entirety by express reference to the
Warrant Agreement and the Warrant Registration Rights Agreement.  All terms
used in this Warrant Certificate that are defined in the Warrant Agreement and
the Warrant Registration Rights Agreement shall have the meanings assigned to
them in such agreements.

                 Copies of the Warrant Agreement and the Warrant Registration
Rights Agreement are on file at the office of the Warrant Agent and may be
obtained by writing to the Warrant Agent at the following address:

                 The Bank of New York
                 101 Barclay Street
                 21 West
                 New York, NY  10286

                 Attention:  Corporate Trust Administration

                 A "Repurchase Event", as defined in the Warrant Agreement,
shall be deemed to occur on any date when the Company consolidates with or
merges into or with (but only where holders of the Common Stock receive
consideration in exchange for all or part of such Common Stock), or sells all
or substantially all of its assets to, another Person which does not have a
class of equity securities registered under the Exchange Act or a wholly owned
subsidiary of such Person, if the consideration for such transaction does not
consist solely of cash or such merger or consolidation is not effected solely
for the purpose of changing the Company's state of incorporation.

            Following a Repurchase Event, the Company must make an offer to
repurchase for cash all outstanding Warrants (a "Repurchase Offer").  If the
Company makes a Repurchase Offer, Holders may, until the expiration date of
such offer, surrender all or part of their Warrants for repurchase by the
Company.

                 Warrants received by the Warrant Agent in proper form during a
Repurchase Offer will, except as otherwise provided in the Warrant Agreement,
be repurchased by the Company at a price in cash (the "Repurchase Price") equal
to the value on the Valuation Date relating thereto of the Common Shares and
other securities or property of the Company which would have been delivered
upon exercise of the Warrants had the Warrants been exercised, less the
Exercise Price (whether or not the Warrants are then exercisable).  The value
of such Common Shares and other securities will be (i) if the Common Shares (or
other securities) are registered under the Exchange Act, determined based upon
the average of the daily market prices (as determined pursuant to Section
3.4(d)(ii)(1) of the Warrant Agreement) of the Common Shares (or other
securities) for the 20 consecutive trading days immediately preceding such
Valuation Date or (ii) if the Common Shares (or other securities)
<PAGE>   52
                                      A-3


are not registered under the Exchange Act or if the value cannot be computed
under clause (i) above, determined by the Independent Financial Expert (as
defined in the Warrant Agreement), in each case as set forth in the Warrant
Agreement.

                 The "Valuation Date" as defined in the Warrant Agreement shall
be deemed to occur on the date five Business Days prior to the date notice of
the Repurchase Offer is first given.

                 If the Company fails to make or complete a Repurchase Offer (a
"Default") as required by the Warrant Agreement, it shall be obligated to
increase the amount otherwise payable pursuant to the Warrant Agreement in
respect of the Repurchase Offer by an amount equal to interest thereon at a
rate per annum of 13% from the date of the Default to the date of payment,
which interest shall compound quarterly.

                 If the Company merges or consolidates with or into, or sells
all or substantially all of its property and assets to, another Person and the
consideration received by holders of Common Shares consists solely of cash, the
Holders of Warrants shall be entitled to receive distributions on the date of
such event on an equal basis with holders of Common Shares (or other securities
issuable upon exercise of the Warrants) as if the Warrants had been exercised
immediately prior to such event (less the Exercise Price).  Upon receipt of
such payment, if any, the rights of a Holder shall terminate and cease and such
Holder's Warrants shall expire.

                 The number of Common Shares purchasable upon the exercise of
each Warrant and the price per share are subject to adjustment as provided in
the Warrant Agreement.  Except as stated in the immediately preceding
paragraph, in the event the Company merges or consolidates with, or sells all
or substantially all of its assets to, another Person, each Warrant will, upon
exercise, entitle the Holder thereof to receive the number of shares of capital
stock or other securities or the amount of money and other property which the
holder of an Common Share (or other securities or property issuable upon
exercise of a Warrant) is entitled to receive upon completion of such merger,
consolidation or sale.

                 As to any final fraction of a share which the same Holder of
one or more Warrant Certificates would otherwise be entitled to purchase upon
exercise thereof in the same transaction, the Company may pay the cash value
thereof determined as provided in the Warrant Agreement.

                 Subject to Article VI of the Warrant Agreement, all Common
Shares issuable by the Company upon the exercise of Warrants shall be validly
issued, fully paid and not subject to any calls for funds, and the Company
shall pay any taxes and other governmental charges that may be imposed under
the laws of the United States of America or any political subdivision or taxing
authority thereof or therein in respect of the issue or delivery thereof
<PAGE>   53
                                      A-4


upon exercise of Warrants (other than income taxes imposed on the Holders).
The Company shall not be required, however, to pay any tax or other charge
imposed in connection with any transfer involved in the issue of any
certificate for Common Shares (including other securities or property issuable
upon the exercise of the Warrants) or payment of cash to any Person other than
the Holder of a Warrant Certificate surrendered upon the exercise of a Warrant
and in case of such transfer or payment, the Warrant Agent and the Company
shall not be required to issue any share certificate or pay any cash until such
tax or charge has been paid or it has been established to the Warrant Agent's
and the Company's satisfaction that no such tax or charge is due.

                 Subject to the restrictions on and conditions to transfer set
forth in Article VIII of the Warrant Agreement, this Warrant Certificate and
all rights hereunder are transferable by the registered Holder hereof, in whole
or in part, on the register of the Company maintained by the Warrant Agent for
such purpose at the Warrant Agent's office in New York, New York, upon
surrender of this Warrant Certificate duly endorsed, or accompanied by a
written instrument of transfer in form satisfactory to the Company and the
Warrant Agent duly executed, with signatures guaranteed as specified in the
attached Form of Assignment, by the registered Holder hereof or his attorney
duly authorized in writing and by such other documentation required pursuant to
the Warrant Agreement and upon payment of any necessary transfer tax or other
governmental charge imposed upon such transfer.  Upon any partial transfer, the
Company will sign and issue and the Warrant Agent will countersign and deliver

Holder of this Warrant Certificate, as such, shall not be entitled to any
rights of a shareholder of the Company, including, without limitation, the
right to vote or to consent to any action of the shareholders, to receive any
distributions, to exercise any pre-emptive right or to receive any

Agreement.

                 This Warrant Certificate shall be void and all rights
evidenced hereby shall cease on March 6, 2007, unless sooner terminated by the

                     MOTOROLA VENDOR FINANCING TEMPLATE
                         MEMORANDUM OF UNDERSTANDING


- -   Motorola agrees that nothing in this Memorandum of Understanding ("MOU") is
    intended or shall operate to amend any provision of, or to restrict, limit,
    increase or otherwise affect any rights or obligations of the parties under
    or pursuant to, that certain Amended, Restated and Consolidated Credit
    Agreement dates as of September 27, 1996 among Nextel Communications, Inc.,
    Nextel Finance Company, the other Restricted Companies named therein,
    Motorola, Inc. and NTFC Capital Corporation, as he same may be amended from
    time to time (the "U.S. Vendor Agreement").  McCaw International Limited
    agrees that certain actions taken under such U.S. Vendor Agreement may
    limit the amount of financing available outside the U.S. to entities
    affiliated with Nextel, or may require McCaw International to make
    repayments of non-U.S. borrowings outstanding, all as more fully provided
    in this MOU.  It is expressly understood and acknowledged by Motorola that
    Nextel and the Restricted Companies shall have no obligation or liability
    of any type or description, contingent or otherwise, on or in respect of
    any amount outstanding pursuant to financing made available, committed or
    extended by Motorola to any Nextel affiliate for use outside the U.S.
    (pursuant to or as contemplated by this MOU).

- -   Motorola desires and intends to provide vendor financing to
    carriers/customers for the roll out-expansion of iDEN systems in the U.S.
    and in certain non-U.S. countries.

- -   Motorola's policy will be to establish a Worldwide limit on the amount of
    vendor financing that can be OUTSTANDING with respect to certain non-U.S.
    countries, for iDEN products, with any particular customer and its
    affiliates or in any particular non-U.S.  country at any point in time,
    that will be based on a ceiling amount of OUTSTANDING vendor financing to
    such customer and its affiliates under both U.S. and non-U.S. facilities.

- -   The issuance of a financing commitment for any specific country shall be in
    Motorola's sole discretion.

- -   Due to this timing of roll outs, drawdowns or loan repayments it is
    possible that the total amount of Motorola vendor financing COMMITMENTS may
    - at times - exceed the worldwide OUTSTANDINGS limit to a customer and its
    affiliates.  In no case, however, can the drawdowns on such commitments
    cause the amounts outstanding to exceed the worldwide OUTSTANDINGS limit.
    Accordingly, drawdowns under the U.S. portion of such commitments may
    result in required repayments of amounts OUTSTANDING under the non-U.S.
    portion of such commitment so that the applicable worldwide OUTSTANDINGS
    limit for the relevant customer and its affiliates is not exceeded.

- -   The worldwide combined OUTSTANDINGS limit for Motorola provide vendor
    financing for Nextel/(i) Nextel and the Restricted Companies under the U.S.
    Vendor Agreement and (ii) McCaw International and its designated affiliates
    has been established, by Motorola, at $400 million, with no more than $125
    million outstanding in any specific country (other than the United States.)
    (See attachment 1 for a description of amounts currently
    outstanding/committed with each of Nextel and McCaw International).

- -   Each worldwide customer financing limit will be reviewed every 2 years and
    adjusted, if desired, prospectively.

- -   Given these objectives/targets, the general terms of all Motorola provide
    vendor financing commitments (other than under the U.S. Vendor Agreement)
    for iDEN products will be as follows:
<PAGE>   2



- -   Vendor Financing will be provided only for the purchase of Motorola iDEN
    good and services and ancillary products and services (such as, without
    limitations, switches which have been ordered from and provided by
    Motorola) to the extent indicated in the relevant definitive financing
    documents.

- -   Working capital loans will not be provided by Motorola - except where
    Motorola is an equity partner and guarantees its % ownership of joint
    venture borrowing.

- -   Appropriate collateral will be required for all vendor financing (i.e.
    channels, licenses, asset pledges, proportionate shareholders guarantees,
    etc.)

- -   Vendor Financing must be Senior Secured Debt.

- -   Vendor Financing will be denominated in and payable in U.S. dollars (and
    will be extended to the relevant borrowing entity in U.S. dollars).

- -   Interest rate for loans will be 2% to 4% over prime depending on the
    country/business plan risk.

- -   There shall be no restriction whatsoever (other than any imposed pursuant
    to relevant law) on Motorola's right to sell, syndicate or assign any
    borrowings made under these non-U.S. vendor financing arrangements.

- -   Political risk insurance will be required on all non-U.S. vendor finance
    unless waived by Motorola.  Fees to be paid by borrower.

- -   There will be no commitment fees on unused commitment amounts.

- -   Arrangement fees on non-U.S. borrowing facilities will be priced at
    approximate market price (generally 1%).

- -   Additional debt will be allowed under the non-U.S. borrowing facilities to
    cover working capital needs within agreed financial covenants.  In certain
    specific, mutually agreed situations Motorola may agree to allow debt that
    is paripassu with Motorola.

- -   All non-U.S. vendor financing provided will be subject to Motorola's
    receipt/approval of acceptable Business Plan(s) and normal due diligence.

ATTACHMENT I


- -   Motorola currently has a debt commitment to the Restricted Companies (as
    defined in the U.S. Vendor Agreement) in the U.S. - as a result of the U.S.
    Vendor Agreement of $305 million.

- -   The amount currently outstanding on this U.S. commitment is $110 million.

- -   Once the other banks party to the Credit Agreement dated as of September
    27, 1996 - entered into in connection with the U.S.  Vendor Agreement -
    have loaned Nextel $827.5 million, Motorola is committed to provide
    additional vendor financing in the U.S.  on a prorate basis with the other
    banks, until the Motorola total amount of outstanding reached a maximum of
    $305 million.

- -   McCaw International has requested that Motorola provide vendor financing,
    for the purchase of Motorola iDEN equipment in the following amounts with
    respect to the following countries during the year 1997, 1998 and 1999.

         - Brazil         $173.5 million
         - Argentina      $ 81.0 million
         - Mexico         $107.5 million
         - Philippines    $ 30.0 million

- -   Motorola has agreed to provide initial financing commitments, contingent on
    the execution of this MOU, for the purchase of Motorola iDEN in the
    following amounts and countries:

         - Brazil         $125 million
         - Philippines    $ 30 million
         - Argentina      $ 81 million

- -   Motorola will continue to review McCaw International's request for
    financing in Mexico to determine the amount of financing, if any, Motorola
    will commit to provide.

- -   Subject to the $400 million limit on Worldwide OUTSTANDINGS to a particular
    customer and its affiliates noted in the Memorandum of Understanding (or
    the $125 million limit to a particular country outside the U.S.), Motorola
    commits to provide vendor financing for the purchase of Motorola iDEN
    equipment, in these 3 countries, PROVIDED THAT


         If the Amount OUTSTANDING in the U.S. under the U.S. Vendor Agreement

                                    PLUS

         The amount OUTSTANDING on non-U.S. vendor financing in these countries

                                    PLUS

         A request for more vendor financing in the U.S. under the Vendor
         Financing Agreement dated September 7, 1996 WHICH CAN NOT BE REFUSED
         PER OUR AGREEMENT WITH THE BANKS

         Would cause the total OUTSTANDINGS amount to exceed $400 million.

         Then McCaw International will repay or cause to repay sufficient
OUTSTANDING non-U.S. loans/borrowings such that after and giving effect to such
repayment, the total amount of loans outstanding from Motorola to Nextel/under
the U.S. Vendor Facility plus the loans outstanding from Motorola to McCaw
International under the non-U.S. facilities will no exceed $400 million.

                       MCCAW INTERNATIONAL (BRAZIL), LTD.

                             SHAREHOLDERS AGREEMENT

<PAGE>   2



         1.2     RESTRICTIVE LEGEND

         Each certificate representing (a) Shares or (b) any other securities
issued in respect of the Shares upon any stock split, stock dividend,

imposed by this Agreement and applicable law as required by Section 10.2.  The
Shareholders consent to the Company' making a notation on its records and
giving instructions to any transfer agent of the Shares in order to implement
the restrictions on Transfer established in this Section 1.

         1.3      RIGHT OF FIRST REFUSAL

                  1.3.1   TRANSFERS BY SHAREHOLDERS

                  Except as otherwise provided in this Agreement, no
Founder may Transfer any interest, direct or indirect, in all or any part of
the Shares owned by such Shareholder (a) during the period beginning on the
date hereof and ending on the date two years and 90 days after the date hereof
(the "Grace Period") and (b) after the expiration of the Grace Period, unless,
in the case of this clause (b) only, (i) the Selling Shareholder shall have
made an offer to sell such Shares to the other Shareholders and the Company as
provided in this Section 1.3 and (ii) such offer shall not have been accepted
in the manner described in this Section 1.3.  No Shareholder (including the
Founders collectively) having beneficial ownership of less than 10% of the
Common Stock at the time of any proposed Transfer by any other Shareholder
shall have rights of first refusal as provided in this Section 1.3.

                  1.3.2   OFFER BY SELLING SHAREHOLDER

                  The offer referred to in Section 1.3.1 shall consist
of a written offer (the "Offer") to the other Shareholders entitled to rights
of first refusal (the "Offerees") to sell the Shares proposed to be Transferred
(the "Offered Shares").  The Offer shall set forth (a) a statement of intention
to effect a Transfer, (b) the number and class of Offered Shares, (c) the terms
and conditions of the proposed Transfer, including (i) the purchase price for
the Offered Shares and (ii) the identity and beneficial ownership of the third
party or parties having made a bona fide offer to purchase the Offered Shares
on  such terms and conditions, and (d) the desired closing date of the
transaction.

                  1.3.3   ACCEPTANCE OF OFFER

                  Within 30 days after its receipt of the Offer, the
Offerees may, at their option, accept the Offer as to all or less than all of
the Offered Shares by giving irrevocable written notice to the Selling
Shareholder, the Company and the other Shareholders prior to the expiration of
such 30-day period.

                  1.3.4    PRO RATA PORTION

                  The Offered Shares shall first be allocated to the
Offerees.  If the Offerees shall not have offered to purchase all the Offered
Shares, the Company may elect to





                                     -2-
<PAGE>   3


purchase any remaining Offered Shares.  To the extent that more than one
Offeree shall have elected to purchase Offered Shares pursuant to Section
1.3.3, each such Offeree may purchase up to its pro rata portion of such
Offered Shares as determined in accordance with this Section 1.3.4.  Each
Offeree's pro rata portion of the Offered Shares is that proportion of the
Offered Shares as the number of shares of voting capital stock of the Company
held by such Offeree bears to the aggregate number of shares of voting capital
stock of the Company held by such Offeree and all other Offerees who have
exercised their rights of first refusal under this Section 1.3.

                  1.3.5   CLOSING

                  If the Offer is accepted as to all the Offered Shares, the
parties shall use their best efforts to complete the closing of such purchase
within 30 days after acceptance of the Offer.  If, after expiration of such
30-day period, the closing of such purchase of all Offered Shares shall not
have occurred (unless closing is subject only to receipt of required
governmental or regulatory approvals) through no fault of the Selling
Shareholder, then the Selling Shareholder may treat the Offer as having been
rejected in its entirety.  If the Offer is not accepted as to all the Offered
Shares as provided in this Section 1.3, or is deemed to be rejected as set
forth in the previous sentence, the Selling Shareholder may for a period of 60
days after such nonacceptance or deemed rejection Transfer the Offered Shares
to the third party or parties designated in the Offer and on the terms and
conditions specified in the Offer.  A proposed Transfer after the expiration of
such 60-day period or on any other terms shall again be subject to the rights
of first refusal and other provisions of this Section 1.

         1.4     TAG-ALONG RIGHTS

                 1.4.1   TRANSFERS BY MIL

                 Except as otherwise provided in this Agreement, neither MIL
nor any Affiliate of MIL may Transfer all or any part of the Shares owned by
MIL or such Affiliate unless (a) MIL or such Affiliate shall have sent to each
other Shareholder (each a "Tag-Along Offeree") a written offer (the "Tag-Along
Offer") to include in such Transfer all or any portion of such Tag-Along
Offeree's Tag-Along Shares (as defined below) at the same price and on the same
terms as MIL or such Affiliate shall Transfer its Shares and (b) such offer
shall not have been accepted in the manner described in this Section 1.4.  Each
Tag-Along Offeree's "Tag-Along Shares," which shall be calculated separately
for each class of Shares included in the Offered Shares, shall mean that number
of Shares of such class as is equal to the number of Shares of such class then
owned by such Tag-Along Offeree multiplied by a fraction, the numerator of
which is the number of Shares of such class being sold by MIL and its
Affiliates and the denominator of which is the number of Shares of such class
then owned by MIL and its Affiliates.

                 1.4.2   TAG-ALONG OFFER

                 The Tag-Along Offer shall consist of a written offer to the
Tag-Along Offerees to include Tag-Along Shares in the Shares proposed to be
Transferred (the "Proposed Shares").  The Tag-Along Offer shall set forth (a) a
statement of intention to effect such a Transfer, (b) the number and class of
Proposed Shares, (c) the terms and conditions of the proposed Transfer,
including the purchase price for the Proposed Shares, and (d) the desired
closing date of the transaction.

                 1.4.3   ACCEPTANCE OF TAG-ALONG OFFER

                 Within 30 days after its receipt of the Tag-Along Offer, each
Tag-Along Offeree may, at its option, accept the Tag-Along Offer as to all or
less than all of such Tag-Along Offeree's Tag-Along Shares by giving
irrevocable written notice to MIL, the Company and the other Shareholders prior
to the expiration of such 30-day period.  Any Tag-Along Shares to be
Transferred by Tag-Along Offerees shall be substituted for an equal number of
Proposed Shares.

                 1.4.4   CLOSING

                 MIL and those Tag-Along Offerees having accepted the Tag-Along
Offer shall use their best efforts to complete the closing of any such Transfer
within 30 days after the end of the 30-day offering period.  If MIL and the
Tag-Along Offerees shall fail to complete such Transfer within such 30-day
closing period (unless closing is delayed due to the need for required
governmental or regulatory approvals), or if MIL and the Tag-Along Offerees
propose to effect a Transfer on different terms than those permitted by the
Tag-Along Offer pursuant to Section 1.4.2, then any proposed Transfer shall
again be subject to all the Transfer restrictions set forth in this Section 1.

         1.5     DRAG-ALONG RIGHTS OF MIL

                 1.5.1   RIGHT TO REQUIRE SALE OF THE COMPANY

                 Notwithstanding the other provisions of this Section 1, if MIL
and its Affiliates seek to effect a transaction involving a bona fide sale of
their entire interest in the Company to an unrelated third party or parties (a
"Buyer"), whether by sale of shares, sale of all or substantially all assets,
merger or otherwise (a "Sale"), the other Shareholders will, upon notice from
MIL after compliance with the provisions of this Section 1.5, take all
commercially reasonable actions required to assist in effecting such Sale,
including, without limitation, Transferring or agreeing to Transfer the Shares
owned by them at a price equal to that at which MIL is Transferring Shares and
otherwise on identical terms and voting in favor of a transaction that results
in such a Transfer. 

                 1.5.2   PROCEDURE

                 MIL shall give written notice to the Company's Board of
Directors (the "Board") and the other Shareholders of MIL's intent to effect a
Sale of the Company.





                                     -4-
<PAGE>   5


MIL may for a period of 180 days after such notice seek to effect a Sale of the
Company to a Buyer.  If such Sale shall not have closed within such 180-day
period (unless closing is delayed due to the need for required governmental or
regulatory approval), any proposed Transfer shall again be subject to all the
Transfer restrictions set forth in this Section 1.

         1.6     NO OTHER TRANSFER EFFECTIVE

         Except as provided in this Section 1, no Transfer of any right, title
or interest in the Shares shall be effective, and the Company shall not record
or recognize any such Transfer, until there has been compliance with the
provisions of this Agreement.  If no Offer is made as herein required, the
Shareholders may nevertheless exercise their rights hereunder as to the Shares
subject to any proposed Transfer, and they may do so at any time, including
after the Transfer of the Shares.

2.       VOTING

         2.1     VOTING OF SHARES

         Each Shareholder shall vote all Shares owned by such Shareholder, or
as to which such Shareholder has voting power, pursuant to the provisions of
this Agreement.


         2.2     ELECTION OF DIRECTORS

         In elections of directors of the Company, the Shareholders shall vote
in favor of (a) one or more candidates designated by the Founders, which
candidates would represent no more than 10% of the directors of the Company;
provided that so long as the Founders shall collectively own 10% or more of the
Common Stock, the Founders shall have the right to designate at least one
candidate for election to the Board and (b) all other candidates, all of whom
shall have been designated by MIL.  If at any time the Founders shall
collectively own less than 10% of the Common Stock, the director or directors
designated for election to the Board by the Founders (the "Founder Director")
shall resign as a director.  The Founders shall not have the right to designate
any candidates for election to the board of directors or comparable governing
body of any subsidiary of the Company.





                                     -5-
<PAGE>   6


         2.3     VOTING TRUST

         If MIL and its Affiliates shall at any time have beneficial ownership
of less than 50% but more than 25% of the Common Stock, the Founders and the
Founder Director shall, subject to their fiduciary duties to the Company and
all Shareholders, execute any legal document required by appropriate law, and
thereafter cast all votes in favor of or against matters to be approved by the
shareholders of the Company or the Board, as the case may be, in the same
manner as MIL and its Affiliates and the directors nominated thereby,
respectively; provided that this Section 2.3 shall not diminish any rights
which the Founders otherwise have under Article Seven of the Company's Articles
of Incorporation.


3.       REPURCHASE AT OPTION OF COMPANY OF COMMON STOCK OWNED BY FOUNDERS

         (a)     If the Founder Director fails to approve any action proposed
to the Board pursuant to Article Seven of the Company's Articles of
Incorporation, or if the holders of Class B Common Stock fail to approve any
such action proposed to the shareholders of the Company, the Company shall have
the right, by written notice to the Founders given within 30 days of the vote
of the Board, and upon approval of a simple majority of the directors of the
Company (excluding the Founder Director), to repurchase all, but not less than
all, of the Common Stock then owned by the Founders.  Such repurchase shall
close within 30 days of the final determination of Fair Market Value, subject
only to completion of the appraisal process and receipt of required
governmental or regulatory approvals.  The repurchase price (the "Repurchase
Price") shall equal the Appraised Fair Market Value (as defined below) of the
Company as of the exercise date multiplied by a fraction, the numerator of
which is the number of shares of Common Stock then owned by the Founders and
the denominator of which is the total number of Shares (calculated on a fully
diluted basis at the stated exercise price of all options).  The Repurchase
Price shall, at the Company's election, be payable in cash, common stock of
Nextel Communications, Inc. ("Nextel Common Stock") or any combination thereof.
Any Nextel Common Stock used as part of the Repurchase Price shall be either
registered with the U.S. Securities and Exchange Commission (the "SEC") or
registrable at the election of the Founders, exercisable by Telcom on behalf of
the Founders, within 30 days after closing of the repurchase right.  The Nextel
Common Stock shall be valued at the average of the closing price of the Nextel
Common Stock on the principal trading market on which such shares are traded
over the 20 trading days prior to closing of the repurchase transaction.  If
paid in cash, the Repurchase Price shall be payable in four equal quarterly
installments, beginning on the date of closing of the repurchase right and on
each three-month anniversary thereof, with interest accruing on the unpaid
principal at an annual rate equal to the annual rate of interest publicly
announced by The Chase Manhattan Bank, N.A., or any successor thereto, in New
York City as its prime rate from time to time (the "Prime Rate") plus 1%.

         (b)     For purposes of this Agreement, "Fair Market Value" means the
price that an unrelated third party would pay if it were to acquire all
outstanding Shares (including all outstanding vested options at the stated
exercise price thereof) in an arm's-length





                                     -6-
<PAGE>   7


transaction, assuming that the Shares were being sold in a manner designed to
attract all possible participants and without taking into consideration a
control premium or minority discount.  The "Appraised Fair Market Value" shall
be determined in accordance with the following procedures:  MIL shall select an
investment banking firm of recognized national standing (the "First
Appraiser"), which shall appraise the Fair Market Value and deliver its
appraisal to the Company, Telcom and MIL, within 60 days of its engagement.  If
Telcom shall disagree with the Fair Market Value determined by such appraiser,
then Telcom shall have the right to appoint an additional investment banking
firm of recognized national standing (the "Second Appraiser").  If Telcom does
not engage a Second Appraiser within 30 days of the First Appraiser's delivery
of its appraisal, the First Appraiser's appraisal shall be the Appraised Fair
Market Value.  If Telcom engages a Second Appraiser, the Second Appraiser will
appraise the Fair Market Value, and deliver its appraisal to the Company,
Telcom and MIL, within 60 days of its engagement.  If such difference between
the two appraisals is less than 20% of the lower appraised value, then the
Appraised Fair Market Value shall be the average of the two appraisals.  If the
difference is greater than or equal to 20% of the lower appraised value, the
two appraisers shall engage a third independent investment banking firm of
recognized national standing (the "Third Appraiser"), which shall appraise the
Fair Market Value within 60 days of its engagement.  The Appraised Fair Market
Value shall be the average of the two appraised values which are closest in
absolute U.S. dollars.  All appraisals of Fair Market Value shall be as of the
date of notice of exercise of the right.  The expenses of the First Appraiser
shall be borne by the Company; the expenses of the Second Appraiser, if any,
shall be borne by the Founders; and the expenses of the Third Appraiser, if
any, shall be borne equally by the Company and the Founders.


4.       FOREIGN OWNERSHIP RULES

         If at any time Brazilian law requires a reduction in the ownership of
the Company by any parties then owning Shares, then

                 (a)     Shares shall be sold on the same date pro
rata by all Shareholders required to sell Shares on the same terms;

                 (b)     such sales shall be at Appraised Fair Market
Value, or as close thereto as achievable under the then-current regulatory
conditions;

                 (c)     such sales shall be made only to purchasers
acceptable to MIL, which acceptance shall not be unreasonably withheld; and

                 (d)     the parties shall use their reasonable best efforts 
to sell such Shares for cash.

5.       CAPITAL CALLS, PREEMPTIVE RIGHTS AND PLEDGES OF COMPANY STOCK

         5.1     GRACE PERIOD FOR FOUNDERS





                                     -7-
<PAGE>   8



         Notwithstanding any capital contributions by any Shareholder to the
Company during the Grace Period, the Founders shall have no obligation to make
any pro rata capital contribution to the Company, and the Shares held by the
Founders as of the date hereof shall retain an aggregate interest in dividends
and other cash or noncash distributions by the Company equal to their aggregate
percentage ownership of the  Common Stock (19% as of the date hereof, as such
percentage may be reduced by the issuance of additional shares of Common Stock
to any third party in accordance with Section 5.2) (the "Founders'
Percentage").  The issuance of Common Stock to MIL or its Affiliates in
connection with any such capital contributions shall not reduce the Founders'
Percentage.

         5.2     PREEMPTIVE RIGHTS

         The Company may at any time issue additional shares of Common Stock to
any third party at fair market value, as determined in good faith by a majority
of the directors of the Company, so long as, after such issuance, the Founders'
Percentage is not reduced to less than 17%.  If the Company intends to issue
additional shares of Common Stock to a third party such that the Founders would
own in the aggregate less than 17% of the Common Stock, the Company shall
deliver to the Founders a written notice at least 30 days prior to such
proposed issuance.  The Founders shall have the right, exercisable upon
irrevocable written notice delivered to the Company at least 10 days prior to
the date of proposed issuance, to purchase additional shares of Common Stock
such that after such issuance, the Founders would own in the aggregate no more
than 17% of the Common Stock; provided that the Founders may exercise their
preemptive rights only if the Founders in the aggregate exercise such rights
with respect to the maximum number of shares of Common Stock permitted
hereunder.  If some but not all of the Founders exercise such right, the number
of shares issuable to each exercising Founder shall bear the same proportion to
the aggregate number of shares issuable to all exercising Founders as the
number of shares held by such exercising Founder prior to such issuance bears
to the aggregate of shares held by all exercising Founders.

         5.3     FOUNDERS' "TRUE-UP" OPTION

         On or prior to the last day of the Grace Period, the Founders shall
have the option, exercisable by Telcom on behalf of the Founders, to pay to the
Company an amount (the "Antidilution Payment") equal to:

         FP x CC
        ---------
          1 - FP

where
"FP" is the Founders' Percentage; and
"CC" is the sum of (a) the aggregate amount of all capital contributions made
to the Company by shareholders other than the Founders during the Grace Period
and (b) the amount of each such capital contribution, multiplied by the Prime
Rate plus 1%, per





                                     -8-
<PAGE>   9


annum, for each capital contribution from the date such contribution was made
to the date of payment of the Antidilution Payment.

         The Company shall deliver to Telcom a notice setting forth the
calculation of the Antidilution Payment at least 30 days prior to the last day
of the Grace Period; provided that the failure of the Company to deliver such
calculation in a timely manner shall not affect the parties' rights and
obligations hereunder; provided, further, that if such notice is not delivered
in a timely manner, Telcom shall pay the Antidilution Payment upon the later of
the last day of the Grace Period and 15 days after delivery of such notice.
Any Antidilution Payment shall be free of all withholding with respect to taxes
of any nature, and if the Founders are required by applicable law to make any
such withholding with respect to any such payment, such Antidilution Payment
shall be increased so that after making all required withholdings, the Company
shall receive an amount equal to the amount it would have received had such
withholdings not been made.  Upon receipt in full of the Antidilution Payment,
the Company shall issue to the Founders on a pro rata basis, based on the
number of shares then owned by each Founder, shares of Common Stock such that
the percentage of the Common Stock owned by the Founders after such transfer
equals the Founders' Percentage.  If Telcom does not make the Antidilution
Payment on the last day of the Grace Period, the Founders' interests in
dividends and other cash or noncash distributions by the Company shall
thereafter be proportionate to their respective shareholdings in the Company.

         If, within the 30-day period prior to the last day of the Grace
Period, (a) MIL shall have offered to sell shares of Common Stock owned by MIL
to Telcom for a price that is the economic equivalent of the transaction
contemplated by the first paragraph of this Section 5.3, (b) Telcom shall have
declined such offer and shall have made the Antidilution Payment to the
Company, resulting in the Company being, in the judgment of a majority of the
Board of Directors, over-capitalized, and (c) the Company immediately makes a
dividend payment to the Shareholders in an aggregate amount less than or equal
to the Antidilution Payment, then Telcom shall immediately make an additional
payment to each Shareholder so that such Shareholder shall have received an
amount equal to the dividend to which such Shareholder would be entitled if no
taxes of any nature were payable with respect to such dividend payment.

         5.4     PLEDGES OF COMMON STOCK

         If the Company or any of the WVB Affiliates shall enter into a
financing arrangement pursuant to which the lender requires the pledge of all
of the Common Stock as security for such financing, and MIL and its  Affiliates
agree to pledge the Common Stock owned by them, then the Founders shall
simultaneously pledge the Common Stock owned by them on the same terms and
conditions as MIL and its Affiliates; provided that such lender shall have no
recourse against the Founders in connection with such financing other than to
the Common Stock so pledged and such pledge shall expressly permit the exercise
and consummation of any repurchase right held by a holder of Class B Common
Stock pursuant to the Company's Articles of Incorporation.

6.       INTEREST OF SPOUSE

         6.1     INTEREST OF SPOUSE SUBJECT TO AGREEMENT

         Any property interest in the Shares now owned or hereafter acquired by
the spouse of a Shareholder shall be subject to the terms of this Agreement and
shall be subject to the same restrictions on Transfer described in Section 1 as
if such interests were owned by a Shareholder and as if such spouse were a
Shareholder.

         6.2     SIGNATURE OF SPOUSES

         Each Shareholder's spouse signing this Agreement acknowledges that he
or she has read this Agreement and understands its contents, specifically this
Section 6.  Notwithstanding the foregoing, absence of a spouse's signature
hereto shall not alter the effectiveness hereof or the enforceability of the
provisions contained herein as against such spouse or any Shareholder.

         Each spouse acknowledges that he or she has had the opportunity to
obtain separate and independent counsel of his or her own choosing prior to
signing this Agreement and has waived such right.  Each spouse agrees that the
Shares and any interest, community or otherwise, he or she has in them are
subject to the provisions of this Agreement.  Each spouse also agrees that his
or her Shareholder-spouse may join in any future amendments or modifications of
this Agreement without any further signature, acknowledgment, agreement or
consent on his or her part and he or she designates his or her
Shareholder-spouse attorney-in-fact for this purpose.  Furthermore, each spouse
agrees to take no action at any time to hinder the operation of this Agreement
as to the Shares in which he or she has an interest.

7.       TERMINATION

         This Agreement shall lapse and be of no further force or effect upon
the first of the following to occur:

                 (a)     Merger, Sale or Liquidation.  The approval by
the Board and the Shareholders, as required by law and by the Company's
Articles of Incorporation and Bylaws, of the merger of the Company with any
other company as a result of which securities representing all or substantially
all of the voting power of the Company are held by Persons that had less than a
majority interest, directly or indirectly, in such securities prior to such
merger, or of the sale of all or substantially all of the assets of the
Company, or of its liquidation.

                 (b)     Agreement of Shareholders.  The written
agreement of holders of not less than 97% of the Common Stock to the
termination of this Agreement.

                 (c)     Public Offering.  The closing of an offering
by the Company of its equity securities to the public pursuant to a
registration statement filed pursuant to the





                                    -10-
<PAGE>   11


U.S. Securities Act of 1933, as amended (the "Act"), or the equivalent
legislation of another country.

                 (d)     Lapse of Time.  The expiration of 21 years
after the death of the last to die of the individual Shareholders named herein.

8.       REGISTRATION RIGHTS

         8.1     DEFINITIONS

                 For purposes of these registration rights:

                 (a)     The terms "register," "registered" and
"registration" refer to a registration effected by preparing and filing a
registration statement or similar document in compliance with the Act, and the
declaration or ordering of effectiveness of such registration statement or
document;

                 (b)     The term "Registrable Securities" means any
Common Stock held by the Holders, including Common Stock issued as (or issuable
upon the conversion or exercise of any warrant, right or other security which
is issued as) a dividend or other distribution with respect to, or in exchange
for or in replacement of, such Common Stock, excluding in all cases, however,
any Registrable Securities sold by a Person in a transaction in which its
rights under this Agreement are not assigned;

                 (c)     The number of shares of "Registrable
Securities then outstanding" shall be determined by the number of shares of
Common Stock outstanding which are, and the number of shares of Common Stock
issuable pursuant to then exercisable or convertible securities which are,
Registrable Securities;

                 (d)     The term "Holder" means MIL, the Founders or any of 
their Affiliates or permitted transferees; and

                 (e)     The term "Initiating Holders" means the
Holders who initiate the request for registration under Section 8.2(a).

         8.2     REQUEST FOR REGISTRATION

         (a)     If at any time following six months after the closing of the
Company's initial public offering, the Company shall receive a written request
from MIL or any of its Affiliates or from Holders of at least 50% of the
Registrable Securities then held by the Founders that the Company file a
registration statement under the Act covering the registration for an
underwritten public offering of Registrable Securities with estimated aggregate
gross proceeds of at least $10,000,000, based on a good-faith estimate of the
market price of the Common Stock, then the Company shall, within 10 days of the
receipt thereof, give written notice of such request to all Holders and shall,
subject to the limitations contained in this Section 8, effect the registration
under the Act of all Registrable Securities which the Holders request to be
registered by their giving written





                                    -11-
<PAGE>   12


notice to the Company within 20 days of the mailing by the Company of its
previous notice to the Holders.

         (b)     The right of any Holder to include its Registrable Securities
in such registration shall be conditioned upon such Holder's participation in
such underwriting and the inclusion of such Holder's Registrable Securities in
the underwriting to the extent provided herein.  All Holders proposing to
distribute their securities through such underwriting shall (together with the
Company as provided in Section 8.4(e)) enter into an underwriting agreement in
customary form with the underwriter or underwriters selected for such
underwriting by a majority in interest of the Initiating Holders, which
underwriter must also be reasonably acceptable to the Company.  Notwithstanding
any other provision of this Section 8.2, if the underwriter advises the Company
in writing that marketing factors require a limitation of the number of shares
to be underwritten, then the Company shall so advise all Holders of Registrable
Securities which would otherwise be underwritten pursuant hereto, and the
number of shares of Registrable Securities that may be included in the
underwriting shall be allocated among all Holders thereof, including the
Initiating Holders, in proportion (as nearly as practicable) to the amount of
Registrable Securities of the Company owned by each Holder.

         (c)     The Company is obligated to effect only one registration
pursuant to this Section 8.2 on behalf of MIL and its Affiliates and one
registration pursuant to this Section 8.2 on behalf of the Founders, their
Affiliates and permitted transferees; provided that, if the number of
Registrable Securities to be registered by either such group is reduced
pursuant to Section 8.2(b) to less than 75% of the Registrable Securities
requested to be registered by such group, such registration shall not be deemed
to be such group's demand registration pursuant to this Section 8.2(c).

         (d)     Notwithstanding the foregoing, if the Company shall furnish to
Holders requesting a registration statement pursuant to this Section 8.2 a
certificate signed by the President of the Company stating that, in the good
faith judgment of the Board, it would be seriously detrimental to the Company
and its shareholders for such registration statement to be filed and it is
therefore essential to defer the filing of such registration statement, the
Company shall have the right to defer such filing for a period of not more than
90 days after receipt of the request of the Initiating Holders.



         8.3     COMPANY REGISTRATION

         If (but without any obligation to do so) the Company proposes to
register (including for this purpose a registration effected by the Company for
shareholders other than the Holders) any of its stock or other securities under
the Act in connection with the public offering of such securities solely for
cash (other than a registration relating solely to the sale of securities to
participants in a Company stock plan, or a registration on any form that does
not include substantially the same information as would be required to be
included in a registration statement covering the sale of the Registrable
Securities), the





                                    -12-
<PAGE>   13


Company shall, at each such time, promptly give each Holder written notice of
such registration.  Upon the written request of each Holder given within 20
days after mailing of such notice by the Company, the Company shall, subject to
the provisions of Section 8.7, cause to be registered under the Act all of the
Registrable Securities that each such Holder has so requested.

         8.4     OBLIGATIONS OF THE COMPANY

         Whenever required under this Agreement to effect the registration of
any Registrable Securities, the Company shall, as expeditiously as reasonably
possible:

                 (a)     Prepare and file with the SEC a registration
statement with respect to such Registrable Securities and use its best efforts
to cause such registration statement to become effective;

                 (b)     Prepare and file with the SEC such amendments
and supplements to such registration statement and the prospectus used in
connection with such registration statement as may be necessary to comply with
the provisions of the Act with respect to the disposition of all securities
covered by such registration  statement;

                 (c)     Furnish to the Holders such numbers of copies
of a prospectus, including a preliminary prospectus, in conformity with the
requirements of the Act, and such other documents as they may reasonably
request in order to facilitate the disposition of all securities covered by
such registration statement;

                 (d)     Use its best efforts to register and qualify
the securities covered by such registration statement under such other
securities or blue sky laws of such jurisdictions as shall be reasonably
requested by the Holders; provided that the Company shall not be required in
connection therewith or as a condition thereto to qualify to do business or to
file a general consent to service of process in any such states or
jurisdictions;

                 (e)     In the event of any underwritten public
offering, enter into and perform its obligations under an underwriting
agreement, in usual and customary form, with the managing underwriter of such
offering.  Each Holder participating in such underwriting shall also enter into
and perform its obligations under such an agreement; and

                 (f)     Notify each Holder of Registrable Securities
covered by such registration statement, at any time when a prospectus relating
thereto covered by such registration statement is required to be delivered
under the Act, of the happening of any event as a result of which the
prospectus included in such registration statement, as then in effect, includes
an untrue statement of a material fact or omits to state a material fact
required to be stated therein or necessary to make the statements therein not

         8.5     FURNISH INFORMATION

         It shall be a condition precedent to the obligations of the Company to
take any action pursuant to this Agreement that the selling Holders shall
furnish to the Company such information regarding themselves, the Registrable
Securities held by them and the intended method of disposition of such
securities as shall be reasonably required to effect the registration of their
Registrable Securities and to execute such documents in connection with such
registration as the Company may reasonably request.

         8.6     EXPENSES OF REGISTRATION

         In connection with any registration pursuant to this Agreement, the
Company shall be responsible for the payment of all expenses of the
registration, with the exception of underwriting commissions and discounts
which shall be paid by the Company, the Holders and any other selling security
holders in proportion to the aggregate value of the securities offered for sale
by each of them.  Notwithstanding the preceding sentence, Holders participating
in a registration pursuant to Section 8.2 shall be responsible for the payment
of all expenses directly related to such registration.

         8.7     UNDERWRITING REQUIREMENTS

         The Company shall not be required under Section 8.3 to include any of
the Holders' securities in an underwritten offering of the Company's securities
unless such Holders accept the terms of the underwriting as agreed upon between
the Company and the underwriters selected by it.  If the total amount of
securities, including Registrable Securities, requested by Holders to be
included in such offering exceeds the amount of securities that the
underwriters reasonably believe compatible with the success of the offering,
then the Company shall be required to include in the offering only that number
of such securities, including Registrable Securities, that the underwriters
believe will not jeopardize the success of the offering.  The securities to be
included in the registration in the event of such a reduction shall be
apportioned first to the Company, then pro rata among the selling Holders
according to the total amount of securities requested to be sold in such
registration by such Holders, or in such other proportions as shall mutually be
agreed to by such selling Holders.

         8.8     DELAY OF REGISTRATION

         No Holder shall have any right to obtain or seek an injunction
restraining or otherwise delaying any such registration as the result of any
controversy that might arise with respect to the interpretation or
implementation of this Agreement.

         8.9     INDEMNIFICATION

         In the event any Registrable Securities are included in a registration
statement under this Agreement:





                                    -14-
<PAGE>   15


                 (a)     To the extent permitted by law, the Company
will indemnify and hold harmless each Holder, the partners, officers, agents,
employees and directors of each Holder, any underwriter (as defined in the Act)
for such Holder and each Person, if any, who Controls (as defined in the Merger
Agreement) such Holder or underwriter within the meaning of the Act or the U.S.
Securities Exchange Act of 1934, as amended (the "1934 Act"), against any
losses, claims, damages or liabilities (joint or several) to which  they may
become subject under the Act, the 1934 Act or other federal or state law,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any of the following statements,
omissions or violations (collectively, a "Violation"):  (i) any untrue
statement or alleged untrue statement of a material fact contained in such
registration statement, including any preliminary prospectus or final
prospectus contained therein, in light of the circumstances under which they
were made, or any amendments or supplements thereto, (ii) the omission or
alleged omission to state therein a material fact required to be stated
therein, or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, or (iii) any
violation or alleged violation by the Company of the Act, the 1934 Act, any
state securities law or any rule or regulation promulgated under the Act, the
1934 Act or any state securities law; and the Company will reimburse each such
Holder, partner, officer, agent, employee or director, underwriter or
Controlling Person for any legal or other expenses reasonably incurred by them
in connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the indemnity agreement contained
in this Section 8.9(a) shall not apply to amounts paid in settlement of any
such loss, claim, damage, liability or action if such settlement is effected
without the consent of the Company, which consent shall not be unreasonably
withheld, nor shall the Company be liable in any such case for any such loss,
claim, damage, liability or action to the extent that it arises out of or is
based upon a Violation occurring in reliance upon and in conformity with
written information furnished expressly for use in connection with such
registration by, or on behalf of, any such Holder, underwriter or Controlling
Person.

                 (b)     To the extent permitted by law, each selling
Holder will indemnify and hold harmless the Company, each of its officers,
directors, agents or employees, each Person, if any, who Controls the Company
within the meaning of the Act, any underwriter and any other Holder selling
securities in such registration statement or any of its partners, officers,
directors, agents or employees or any Person who Controls such Holder, against
any losses, claims, damages or liabilities (joint or several) to which the
Company or any such officer, director, agent, employee, Controlling Person, or
underwriter, or other such Holder or its partner, officer, director, agent,
employee or Controlling Person may become subject, under the Act, the 1934 Act
or other federal or state law, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
Violation, in each case to the extent (and only to the extent) that such
Violation occurs in reliance upon and in conformity with written information
furnished by, or on behalf of, such Holder expressly for use in connection with
such registration; and each such Holder will reimburse any legal or other
expenses reasonably incurred by the Company or any such partner, officer,
director, agent, employee, Controlling Person, underwriter or other such
Holder, partner, officer, director, agent, employee or





                                    -15-
<PAGE>   16


Controlling Person in connection with investigating or defending any such loss,
claim, damage, liability or action; provided, however, that the indemnity
agreement contained in this Section 8.9(b) shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of the Holder, which consent shall
not be unreasonably withheld.

                 (c)     Promptly after receipt by an indemnified
party under this Section 8.9 of notice of the commencement of any action
(including any governmental action), such indemnified party will, if a claim in
respect thereof is to be made against any indemnifying party under this Section
8.9, deliver to the indemnifying party a written notice of the commencement
thereof, and the indemnifying party shall have the right to participate in,
and, to the extent the indemnifying party so desires, jointly with any other
indemnifying party similarly notified, to assume the defense thereof with
counsel mutually satisfactory to the parties; provided, however, that an
indemnified party shall have the right to retain its own counsel, with the fees
and expenses to be paid by the indemnifying party, if, in the opinion of
counsel for the indemnifying party, representation of such indemnified party by
the counsel retained by the indemnifying party would be inappropriate due to
actual or potential differing interests between such indemnified party and any
other party represented by such counsel in such proceeding.  The failure to
deliver written notice to the indemnifying party within a reasonable period of
time of the commencement of any such action shall relieve such indemnifying
party of any liability to the indemnified party under this Section 8.9 to the
extent prejudicial to its ability to defend such action, but the omission so to
deliver written notice to the indemnifying party will not relieve it of any
liability that it may have to any indemnified party otherwise than under this
Section 8.9.

         8.10    "MARKET STAND-OFF" AGREEMENT

         The Holders hereby agree that they shall not, to the extent reasonably
requested by the Company and an  underwriter of Common Stock (or other
securities) of the Company, sell or otherwise transfer or dispose of (other
than to donees who agree to be similarly bound) any Registrable Securities for
180 days following the effective date of a registration statement of the
Company filed under the Act; provided, however, that all officers and directors
of the Company and all other Persons with registration rights (whether or not
pursuant to this Agreement) enter into similar agreements.  In order to enforce
the foregoing covenant, the Company may impose stop-transfer instructions with
respect to the Registrable Securities of the Holders (and the shares or
securities of every other Person subject to the foregoing restriction) until
the end of such period.

         8.11    RIGHT TO TERMINATE REGISTRATION

         The Company shall have the right to terminate or withdraw any
registration initiated by it under this Section 8 prior to the effectiveness of
such registration whether or not any Holder has elected to include securities
in such registration.

Controlled by such Shareholder to control of policymaking or day-to-day

         votes per share and each share of Class B Common Stock having 10/19
         votes per share.

                          B.      Board of Directors.  The holders of the
         outstanding shares of Class A Common Stock ("Class A Holders") shall
         have the right, as a class, to elect nine Directors.  The holders of
         the outstanding shares of Class B Common Stock ("Class B Holders")
         shall have the right, as a class, to elect one Director.

                          C.      Redemption Right of Class B Common Stock.
         Class B Holders shall be entitled to cause the Corporation to redeem
         all outstanding shares of Class B Common Stock on the terms set forth
         below.

                                  (i)      At any time after October 31, 2001
         and prior to November 1, 2003, or at any time after a Change of
         Control shall have occurred, the holder or holders of a majority of
         the then outstanding shares of Class B Common Stock may deliver a
         request for redemption to the Corporation, and upon receipt of such a
         request the Corporation shall be required to redeem all outstanding
         shares of Class B Common Stock on the terms specified below.

                                  (ii)     The Corporation shall schedule a
         closing (the "Closing") for such redemption on a date selected by the
         Corporation within six months of delivery of such notice, subject only
         to receipt of all required governmental or regulatory approvals, and
         shall promptly notify all Class B Holders of the time, date and place
         of the Closing.

                                  (iii)    At the Closing, the Corporation
         shall redeem all outstanding shares of Class B Common Stock for a
         price (the "Redemption Price") equal to the Appraised Fair Market
         Value of the Corporation as of the exercise date, multiplied by a
         fraction, the numerator of which is the number of shares of Class B
         Common
<PAGE>   24
         Stock outstanding and the denominator of which is the number of shares
         of Common Stock (calculated on a fully-diluted basis at the stated
         exercise price of all options) then outstanding.  The Redemption Price
         shall, at the Corporation's election, be payable in cash,
         publicly-traded common stock of any entity owning not less than 50% of
         the outstanding shares of Class A Common Stock ("Public Company Common
         Stock") or any combination thereof.  Any Public Company Common Stock
         transferred as part of the Redemption Price shall be shares that are
         registered with the Securities and Exchange Commission or that are
         required to be so registered within 30 days after the Closing.  The
         Public Company Common Stock shall be valued at the average of the
         closing prices on the principal market on which such stock is traded
         during the 20 trading days prior to the Closing.  If paid in cash, the
         Redemption Price shall be payable in four equal quarterly
         installments, beginning on the date of closing of the repurchase right
         and on each three-month anniversary thereof, with interest accruing on
         the unpaid principal at the Prime Rate plus 1%.

                          For purposes of these Articles of Incorporation, a
         "Change of Control" means the acquisition by any person, entity or
         group after January 31, 1997 of the power, directly or indirectly, to
         elect a majority of the Corporation's Directors.

                          For purposes of these Articles of Incorporation,
         "Fair Market Value" means the price that an unrelated third party
         would pay if it were to acquire all outstanding equity interests of
         the Corporation (including all outstanding vested options) in an
         arm's-length transaction, assuming that such interests were being sold
         in a manner designed to attract all possible participants and without
         taking into consideration a control premium or minority discount.  The
         "Appraised Fair Market Value" shall be determined in accordance with
         the following procedures:  the Corporation shall select an investment
         banking firm of recognized national standing which has not provided
         services to the Corporation or any affiliate of the  Corporation (an
         "Independent Appraiser") within the preceding 24 months (the "First
         Appraiser") which shall appraise the Fair Market Value and deliver its
         appraisal to the Corporation and the Class B Holders within 60 days of
         its engagement.  If the majority of the Class B Holders shall disagree
         with the Fair Market Value determined by such Independent Appraiser
         then the majority of Class B Holders shall have the right to appoint
         an additional Independent appraiser (the "Second Appraiser").  If the
         Class B Holders do not engage a Second Appraiser within 30 days of the
         First Appraiser's delivery of its appraisal, the First Appraiser's
         appraisal shall be the Appraised Fair Market Value.  If the Class B
         Holders engage a Second Appraiser, the Second Appraiser will appraise
         the Fair Market Value, and deliver its appraisal to the Corporation
         and the Class B Holders within 60 days of its engagement.  If such
         difference between the two appraisals is 20% or less of the lower
         appraised value, the Appraised Fair Market Value will be the average
         of the two appraisals.  If such difference between the two appraisals
         is more than 20% of the lower appraised value, the two appraisers
         shall engage a third Independent Appraiser (the "Third Appraiser"),
         which shall appraise the Fair Market Value within 60 days of its
         engagement.  The Appraised Fair Market Value
<PAGE>   25
         shall be the average of the two appraised values which are closest in
         absolute dollars.  All appraisals of Fair Market Value shall be as of
         the date of receipt by the Corporation of the request for redemption
         right.  The expenses of the First Appraiser shall be borne by the
         Corporation; the expenses of the Second Appraiser, if any, shall be
         borne by the Class B Holders, and the expenses of a Third Appraiser,
         if any, shall be borne equally by the Corporation on the one hand and
         the Class B Holders on the other hand.

                          For purposes of these Articles of Incorporation,
         "Prime Rate" means the rate announced by The Chase Manhattan Bank,
         N.A., or any successor thereto, in New York City from time to time as
         its "base" or "prime" rate.

                          D.      No Preemptive Rights.  The Class A Holders
         and the Class B Holders shall have no preemptive right to purchase or
         subscribe for any shares of capital stock of the Corporation of any
         class whether now or hereafter authorized or any securities
         convertible into or exchangeable for shares of Common Stock.

                          E.      Other Rights.  Except as otherwise stated
         herein, the rights of shares of Class A Common Stock and Class B
         Common Stock shall be equal in all respects.

         THIRD:  The purpose of the corporation is to engage in any lawful
activity for which corporations may be organized under the Virginia Stock
Corporation Act.

         FOURTH:  No officer or Director shall be personally liable to the
Corporation or its shareholders in any proceedings brought by a shareholder in
the right of the Corporation or brought by or on behalf of shareholders of the
Corporation, for monetary damages assessed against an officer or Director
arising out of a single transaction, occurrence or course of conduct.
Notwithstanding the foregoing sentence, an officer or Director shall be liable
to the extent provided by applicable law for (i) willful misconduct, (ii) a
knowing violation of criminal law, (iii) a knowing violation of federal or
state securities law, including, without limitation, insider trading or
manipulation of the market for any security, or (iv) any transaction from which
the officer or Director derived an improper personal benefit.  Neither the
subsequent amendment or repeal of this Article FOURTH shall apply to or have
any effect on the liability of any officer or Director of the Corporation for
or with respect to any acts or omissions of such officer or Director occurring
prior to the date of any amendment or repeal of this Article FOURTH.

         FIFTH:  The following actions shall require the affirmative vote of
two-thirds of the number of Directors in office, including the Director elected
by the Class B holders:

                          (a)     The amendment of the Articles of
Incorporation or Bylaws of the Corporation other than in the ordinary course of
business.

                          (b)     The creation of any equity security senior to
the existing Common Stock or the amendment of any provision or rights of the
existing classes of capital stock.
<PAGE>   26
                          (c)     Permitting or causing the Corporation or any
of its material subsidiaries to issue voting securities that have voting rights
different from those to which then-issued voting securities are entitled.

                          (d)     The dissolution, liquidation or spin-off of
the Corporation or any material WVB Affiliates (as defined in the Agreement and
Plan of Merger relating to the Corporation dated as of October 28, 1996 (the
"Merger Agreement")) or any portion thereof, or merging or effecting any
acquisition involving the Corporation or any material WVB Affiliates, or
selling all or substantially all of the Corporation's (or any material WVB
Affiliate's) assets, except (i) as provided in the Merger Agreement or (ii) in
transactions involving only the Corporation and Affiliates of the Corporation.

                          (e)     Permitting or causing the Corporation or any
of its subsidiaries (or any other Person to the extent the  Corporation
directly or indirectly controls such Person) to enter into any material
contract, agreement or undertaking with McCaw International, Ltd. or any of its
Affiliates (other than the Corporation or its subsidiaries) other than on an
arm's-length, fair-market-value basis.

                          (f)     Permitting or causing the Corporation or any
of its Affiliates to issue, allot or dispose of securities or rights to receive
securities of the Company, including options (but excluding employee options),
other than for cash at fair market value.

         For purposes of these Articles of Incorporation, "Affiliate" of any
Person (the "Subject") shall mean any other Person that, directly or
indirectly, Controls or is Controlled by or is under common Control with the
Subject.

         For purposes of these Articles of Incorporation, "Control" (including,
with correlative meanings, the terms "Controlled by" and "under common Control
with"), as used with respect to any Person, means the possession, directly or
indirectly, of the power to direct or cause the direction of the management and
policies of such Person, whether through the ownership of voting securities or
by contract or otherwise.

any individual, partnership, joint-stock company, limited liability company,

                     MCCAW INTERNATIONAL (ARGENTINA), LTD.

                               MEMBERS AGREEMENT

         THIS MEMBERS AGREEMENT (this "Agreement") is made as of May 6, 1997,
by and among McCaw International (Argentina), Ltd., a Cayman Islands company
(the "Company"), and the persons listed as Members on Exhibit I attached
hereto, as amended from time to time, including McCaw International (Holdings),
Ltd., a Cayman Islands company ("MIL"), and Wireless Ventures of Argentina,
L.L.C., a Delaware limited liability company ("WVA") (collectively, the
"Members" and, individually, a "Member").

                                    RECITALS

         A.      The Members are the owners of all the Company's issued share
capital (the "Ordinary Shares").  The Members desire to enter into certain
agreements relating to transfers of Ordinary Shares and the corporate
governance of the Company.

         B.      It is the intent of the parties that MIL and its Affiliates
(as defined in the Company's Articles of Association) shall have operational
control of the Company in accordance with and subject to the provisions of this
Agreement and the Memorandum and Articles of Association of the Company, so
long as MIL and its Affiliates own at least 30% of the then issued Ordinary
Shares, including any other securities issued with respect to the Ordinary
Shares by way of a dividend or split or in connection with a combination of
shares, recapitalization, merger, consolidation or other reorganization and any
other securities convertible into or exercisable for any such securities
(collectively, the "Shares").

                                   AGREEMENT

         NOW, THEREFORE, for good and valuable consideration the receipt and
sufficiency of which are acknowledged and to further the interests of the
Company and its present and future Members, the parties agree as follows:

1.       DEFINED TERMS

         All capitalized terms used but not defined herein have the meanings
set forth in the Company's Memorandum and Articles of Association, as they may
be amended from time to time (the "Articles").

         For purposes of this Agreement, "Affiliate" of any Person (the
"Subject") shall mean any other Person that, directly or indirectly, Controls
or is Controlled by or is under common Control with the Subject.

         For purposes of this Agreement, "Control" (including, with correlative
meanings, the terms "Controlled by" and "under common Control with"), as used
with respect to any Person, means the possession, directly or indirectly, of
the power to direct or cause the direction of the management and policies of
such Person, whether through the ownership of voting securities or by contract
or otherwise.





<PAGE>   2



         For purposes of this Agreement, "Person" shall mean any individual,
partnership, joint-stock company, limited liability company, firm, corporation,
association, unincorporated organization, joint venture, trust or other entity.

2.       VOTING

         2.1     VOTING TRUST

                 If MIL and its Affiliates shall at any time have beneficial
ownership of less than 50% but more than 25% of the Shares, WVA and its
Affiliates shall and shall cause the WVA Directors to, subject to their
fiduciary duties to the Company and all Members, execute any legal document
required by appropriate law, and thereafter cast all votes in favor of or
against matters to be approved by the Members or the Board, as the case may be,
in the same manner as MIL and its Affiliates and the directors nominated
thereby, respectively; provided, however, that this Section 2 shall be subject
to and shall not diminish any rights which WVA and its Affiliates otherwise
have under this Agreement and the Articles; provided, further, that the
provisions of this Section 2 shall not apply to any vote of the directors of
the Company with respect to the redemption by the Company of all the Shares
held by MIL and its Affiliates pursuant to Article 11(c) of the Articles.

         2.2     DRAG-ALONG RIGHTS

         MIL and WVA agree to take all commercially reasonable actions required
to assist in effecting a Sale pursuant to Article 9(d)(i) of the Company's
Articles of Association including but not limited to voting in favor of such
Sale and causing the Directors appointed by MIL and WVA, subject to their
fiduciary duties to the Company and to all of the Members, to vote in favor of
such Sale.

3.       BUSINESS PLANS; CAPITAL CALLS; DEBT

         The Company shall adopt the Initial Plan substantially in the form
presented by MIL to WVA on October 25, 1996 and a new Business Plan upon the
expiration of each prior Business Plan, and shall operate the business in
compliance with each Business Plan.  Each Member shall be deemed to have
consented to any capital calls reasonably required by each Business Plan, so
long as (i) the earnings before interest, tax, depreciation and amortization of
the Company ("EDITDA") for the period beginning at the commencement of such
Business Plan and ending as of the last day of such fiscal year are greater
than 70% of the EDITDA projected for such period in such Business Plan and (ii)
the consolidated capital expenditures of the Company for the period beginning
at the commencement of such Business Plan at any time are less than the amount
of capital expenditures projected in such Business Plan for the three years of
such Business Plan.  Each Member may contribute its pro rata share of any such
capital call by the Company in exchange for the issuance by the Company to such
Member of fully paid and non-assessable shares in the share capital of the
Company, with the price of such shares being equal to their fair value as
determined by the Board.  To the extent any Member fails to contribute its pro
rata share of any such capital call, such failure shall not create any debt,
liability or engagement to or with the Company by such Member; however, such
Member's percentage ownership in the Company shall be diluted as a result of
the issuance of new share capital of the Company pursuant to the





                                     -2-
<PAGE>   3


third sentence of this Section 3, based on the  valuation of the Invested
Capital contributed or deemed to have been contributed by the parties pursuant
to Section 2.1 of the Joint Venture Agreement dated as of October 28, 1996, as
amended as of April 25, 1997, among McCaw International, Ltd., McCaw
International (Delaware), Ltd., McCaw International (Holdings), Ltd., MIL,
Telcom Ventures, LLC and WVA and, without double-counting, the full face value
of subsequent capital contributions made by the Members.  In furtherance of the
foregoing, the Members agree to exercise their voting rights to increase the
authorized share capital of the Company from time to time as may be necessary
to ensure that the Company has an adequate number of authorized but unissued
shares available for issuance pursuant to the Business Plan.  The Company shall
seek to maintain a debt-to-equity ratio of at least 1.5 to 1, subject to the
availability of debt financing on commercially reasonable terms.

4.       TERMINATION

         This Agreement shall lapse and be of no further force or effect upon
the first of the following to occur:

                          (a)     Merger, Sale or Liquidation.  The approval by
the Board and the Members, as required by law and by the Articles, of the
merger of the Company with any other company as a result of which Shares
representing all or substantially all of the voting power of the Company are
held by Persons that had less than a majority interest, directly or indirectly,
in such securities prior to such merger, or of the sale of all or substantially
all of the assets of the Company, or of its liquidation.

                          (b)     Agreement of Members.  The written agreement
of holders of not less than 90% of the Shares to the termination of this
Agreement.

                          (c)     Public Offering.  The closing of an offering
by the Company of its equity securities to the public pursuant to a
registration statement filed pursuant to the U.S. Securities Act of 1933, as
amended, or the equivalent legislation of another country.

                          (d)     Lapse of Time.  The final expiration or
termination of all paging and trunking licenses owned by the direct and
indirect subsidiaries of the Company.

                          (e)     Share Ownership.  At such time as (i) MIL and
its Affiliates collectively own less than 10% of the Shares and (ii) WVA and
its Affiliates collectively own less than 10% of the Shares.

5.       NONCOMPETITION

         Each Member agrees that, until one year following termination of this
Agreement with respect to such Member, neither such Member nor any Affiliate
Controlled by such Member shall in any way, by action or inaction, directly or
indirectly, for itself or for the benefit of any other Person, own, manage,
operate, join, Control or participate in the ownership, management, operation
or Control of any Person that competes with the Company or any Affiliate
thereof, or agrees to do any of the foregoing, in the business of paging or

manufacture and sale of related software and hardware products.  In addition,
neither any Member nor any Affiliate Controlled by such Member may maintain an
equity interest in any Person (other than the Company) in which it owns an
equity interest as of the date hereof, which equity interest entitles any
Member or any Affiliate Controlled by such Member to control of policymaking or
day-to-day operations of such Person or in connection with which any Member or
any Affiliate Controlled by such Member has a representative on the board of
directors, if such Person elects to engage in the business of cellular
communications or personal communications systems in Argentina.

6.       OPTION

         The Company hereby grants each of MIL and WVA an option to require the
Company to repurchase at a price of US$1.00 per share the number of shares of
its share capital equal to the amount of any Shortfall (as defined in the Joint
Venture Agreement dated as of October 28, 1996 and amended as of April 25, 1997
by and among McCaw International, Ltd., McCaw International (Delaware), Ltd.,
MIL, McCaw International (Argentina) LLC, Telcom Ventures, LLC and WVA, (the
"Joint Venture Agreement")) owed to the JVC by MIL or WVA, as the case may be,
divided by $1.00, in exchange for the termination of the obligation of MIL or
WVA, as the case may be, to pay the Shortfall.  Such option may be exercised by
MIL or WVA, as the case may be, giving the Company at least ten days' prior
written notice specifying the date (which shall be a Business Day not more than
20 days after the date of such notice) on which the repurchase shall be made
and the number of shares to be repurchased.  Such options shall terminate upon
the satisfaction of the obligations of MIL and WVA under Section 2.3 of the
Joint Venture Agreement.

                               THE JOINT VENTURE

2.1      ESTABLISHMENT OF THE JOINT VENTURE

         2.1.1    CORPORATE STRUCTURE

         The parties acknowledge that the apparent preferred structure for the
transactions contemplated hereby is (in descending order of preference): (i) a
business combination of the parties' respective Argentina operating companies
pursuant to a joint venture, merger or partnership; (ii) the creation of a
non-U.S. entity to which the parties would contribute their 

                                     -5-

<PAGE>   12

respective Argentina holdings; (iii) the acquisition by each party of a 50%
interest in the other party's operating companies in Argentina; or (iv) a
business combination of the parties' respective Argentina holding companies
outside of the United States and outside of Argentina. In the event that a party
(the "First Party") to this Agreement shall determine prior to Closing that the
structure of the transaction contemplated hereby can be accomplished by means of
an alternate structure that is more tax-efficient for such party, or that does
not require governmental or other approvals, and if such alternate structure is
advantageous or neutral to the other party, then the First Party shall propose
to restructure the alternate structure. If the parties are unable to agree on an
alternate structure after negotiating in good faith, then the transaction shall
be consummated using the structure described in clause (i) of this Section
2.1.1.

         2.1.2    TRANSFERS

         On a date (the "Closing Date") as soon as reasonably practicable after

common Control to own at least 200 SMR channels in a single Argentine city (the
"Authorization"), the following shall occur simultaneously, upon the terms and
subject to the conditions of this Agreement:

                  (a)      MIL and Telcom shall implement the structure
mutually agreed upon pursuant to Section 2.1.1.

                  (b)      MIL Holdings or Telcom, as the case may be, shall
contribute cash (the "True-Up") to MIL Argentina, such that after such cash
capital contribution, (i) the sum of (x) $10,000,000 (the value of the McCaw
S.A. Assets as of the date hereof), (y) all cash equity investments by MIL and
its Affiliates in McCaw S.A. and the Paging Joint Venture, less any cash
dividends or other cash or noncash distributions to MIL Holdings and its
Affiliates by McCaw S.A. and the Paging Joint Venture, in each case between the
date hereof and the Closing Date, and (z) the True-Up paid by MIL Holdings, if
any (the "MIL Invested Capital"), is equal to (ii) the sum of (x) $10,000,000
(the value of the WVA Assets as of the date hereof), (y) all cash equity
investments by the WVA Securityholders and their Affiliates in the WVA
Subsidiaries and the Paging Joint Venture, less any cash dividends or other
cash or noncash distributions to the WVA Securityholders and their Affiliates
by WVA and the Paging Joint Venture, in each case between the date hereof and
the Closing Date, and (z) the True-Up paid by Telcom, if any (the "Telcom
Invested Capital"; together with the MIL Invested Capital, the "Invested
Capital"); provided that "Invested Capital" shall exclude contributed services
or intangible rights in excess of the cash would have been paid to the party
contributing such services or rights in an arm's-length transaction with a
non-affiliate.

                  (c)      The note payable by MIL Argentina to WVA in
connection with the joint venture in the Paging Agreement shall have been
cancelled.

consolidated long-term liabilities; the consolidated current liabilities of MIL
Argentina shall not exceed the consolidated current assets of MIL Argentina by
more than $1,000,000, and the consolidated current liabilities of WVA shall not
exceed the consolidated current assets of WVA by more than $1,000,000.

         2.1.3    MEMORANDUM OF ASSOCIATION

         On the Closing Date, the Shareholders of MIL Argentina shall cause the
Memorandum of Association of MIL Argentina to be amended as necessary to effect
the transactions contemplated by this Agreement and the Shareholders Agreement,
and shall be the Memorandum of Association of MIL Argentina after the Closing

MIL Argentina and McCaw S.A. as of the Closing Date (the "MIL Closing Balance
Sheet), both of which shall have been reviewed by MIL Argentina's regular
independent accountants, together with detailed support for such calculation,
and Telcom shall provide to MIL (i) a statement certifying its calculation of
Telcom Invested Capital and (ii) a consolidated balance sheet of WVA and the
WVA Subsidiaries as of the Closing Date (the "WVA Closing Balance Sheet"), both

support for such calculation. All calculations shall be derived from the
consolidated financial statements of MIL Argentina and WVA, which shall have
been prepared in accordance with U.S. generally accepted accounting principles
and with accounting policies and practices consistent with those used in
preparation of the MIL Argentina Financial Statements and the WVA Financial
Statements, respectively. MIL Argentina's regular independent accountants shall
verify that MIL had no liabilities and KPMG Peat Marwick shall verify that WVA

<PAGE>   14

         (b) To the extent that the MIL Closing Balance Sheet indicates that
the consolidated current liabilities of MIL Argentina and McCaw S.A. exceeded
the consolidated current assets of MIL Argentina and McCaw S.A. as of the
Closing Date by more than US$1,000,000 (any such excess being referred to
herein as the "MIL Working Capital Excess"), MIL shall pay MIL Argentina the
MIL Working Capital Excess in cash within 15 days of MIL's delivery of the MIL
Closing Balance Sheet. To the extent that the WVA Closing Balance Sheet
indicates that the consolidated current liabilities of WVA and the WVA
Subsidiaries exceeded the consolidated current assets of WVA and the WVA
Subsidiaries as of the Closing Date by more than US$1,000,000 (any such excess
being referred to herein as the "WVA Working Capital Excess"), Telcom shall pay
MIL Argentina the WVA Working Capital Excess in cash within 15 days of Telcom's
delivery of the WVA Closing Balance Sheet.

         (c) If MIL disagrees with Telcom's calculation of the WVA Working
Capital Excess, MIL may, within 15 days of the delivery of the WVA Closing
Balance Sheet, deliver a notice to Telcom disagreeing with such calculation and
setting forth its calculation. Any such notice of disagreement shall specify
those items or amounts as to which MIL disagrees, and MIL shall be deemed to
have agreed with all other items and amounts contained in the WVA Closing
Balance Sheet and the calculation of the WVA Working Capital Excess delivered
pursuant to Section 2.3(b).

         (d) If Telcom disagrees with MIL's calculation of the MIL Working
Capital Excess, Telcom may, within 15 days of the delivery of the MIL Closing
Balance Sheet, deliver a notice to MIL disagreeing with such calculation and
setting forth its calculation. Any such notice of disagreement shall specify
those items or amounts as to which Telcom disagrees, and Telcom shall be deemed
to have agreed with all other items and amounts contained in the MIL Closing
Balance Sheet and the calculation of the MIL Working Capital Excess delivered
pursuant to Section 2.3(b).

         (e) If a notice of disagreement shall be delivered by MIL pursuant to
Section 2.3(c), MIL and Telcom shall, during the 15 days following such
delivery, use their best efforts to reach agreement on the disputed items or
amounts in order to determine, as may be required, the amount of the WVA
Working Capital Excess, which amount shall not be less than the amount thereof
shown in Telcom's calculations delivered pursuant to Section 2.3(b) or more
than the amount thereof shown in MIL's calculation delivered pursuant to
Section 2.3(c). If, during such period, MIL and Telcom are unable to reach such
agreement, they shall promptly thereafter cause an independent accounting firm
of nationally recognized standing reasonably satisfactory to MIL and Telcom
(which shall not have any material relationship with MIL or Telcom or any of
their Affiliates (the "Accountants")), promptly to review this Agreement and
the disputed items or amounts for the purpose of calculating the WVA Working
Capital Excess. Telcom, WVA and the WVA Subsidiaries shall provide all detailed
documentation necessary to support the computation underlying Telcom's
calculation of the WVA Working Capital Excess. In making such calculation, the
Accountants shall consider only those items or amounts in the WVA Closing
Balance Sheet or 

                                     -8-

<PAGE>   15

Telcom's calculation of the WVA Working Capital Excess as to which MIL has
disagreed. The Accountants shall deliver to MIL and Telcom, as promptly as
practicable, a report setting forth such calculation. Such report shall be final
and binding upon MIL and Telcom. The cost of such review and report shall be
borne (i) by MIL if the difference between the WVA Working Capital Excess and
MIL's calculation of the WVA Working Capital Excess delivered pursuant to
Section 2.3(c) is greater than the difference between the WVA Working Capital
Excess and Telcom's calculation of the WVA Working Capital Excess delivered
pursuant to Section 2.3(b), (ii) by Telcom if the first such difference is less
than the second such difference, and (iii) otherwise equally by MIL and Telcom.

         (f) If a notice of disagreement shall be delivered by Telcom pursuant
to Section 2.3(d), MIL and Telcom shall, during the 15 days following such
delivery, use their best efforts to reach agreement on the disputed items or
amounts in order to determine, as may be required, the amount of the MIL
Working Capital Excess, which amount shall not be less than the amount thereof
shown in MIL's calculations delivered pursuant to Section 2.3(b) or more than
the amount thereof shown in Telcom's calculation delivered pursuant to Section
2.3(d). If, during such period, MIL and Telcom are unable to reach such
agreement, they shall promptly thereafter cause the Accountants promptly to
review this Agreement and the disputed items or amounts for the purpose of
calculating the MIL Working Capital Excess. MIL, MIL Argentina and McCaw S.A.
shall provide all detailed documentation necessary to support the computation
underlying MIL's calculation of the MIL Working Capital Excess. In making such
calculation, the Accountants shall consider only those items or amounts in the
MIL Closing Balance Sheet or MIL's calculation of the MIL Working Capital
Excess as to which Telcom has disagreed. The Accountants shall deliver to MIL
and Telcom, as promptly as practicable, a report setting forth such
calculation. Such report shall be final and binding upon MIL and Telcom. The
cost of such review and report shall be borne (i) by Telcom if the difference
between the MIL Working Capital Excess and Telcom's calculation of the MIL
Working Capital Excess delivered pursuant to Section 2.3(d) is greater than the
difference between the MIL Working Capital Excess and Telcom's calculation of
the MIL Working Capital Excess delivered pursuant to Section 2.3(d), (ii) by
MIL if the first such difference is less than the second such difference, and
(iii) otherwise equally by MIL and Telcom.

         (g) MIL Argentina shall engage, at its expense, the Accountants
to review the information provided by MIL and Telcom pursuant to Section 2.3(a)
with respect to the calculations of Invested Capital.  Within 30 days after the
Closing Date, the Accountants shall provide to MIL Argentina a verification of
the calculations of the Invested Capital.

         (h) To the extent the Accountants' calculations differ from those used
in Section 2.1.2(b) such that one party would have been required to make an
additional cash contribution pursuant to Section 2.1.2(b) (the "Shortfall"),
the party owing the Shortfall shall make such additional cash contribution to
MIL Argentina within 10 days of the Accountants' delivery of their
calculations. If the party owing the Shortfall shall fail to make such
additional cash contribution, MIL Argentina shall issue additional equity
interests to the other party 

                                     -9-

<PAGE>   16

hereto such that each party's interest is proportionate to its capital
contributions pursuant to Section 2.1.2(b), taking into account the Accountants'
calculation of the Invested Capital, MIL Working Capital Excess and WVA Working
Capital Excess.

         (i) MIL and Telcom agree that they will, and agree to cause their
respective independent accountants, McCaw S.A., WVA and the WVA Subsidiaries
to, cooperate and assist in the Accountants' review of the Invested Capital,
the MIL Closing Balance Sheet, the WVA Closing Balance Sheet, the MIL Working
Capital Excess and the WVA Working Capital Excess, including, without
limitation, the making available to the extent necessary of books, records,
work papers and personnel.

material adverse effect on McCaw S.A.

         Where registration of the intellectual property listed in clauses (a)
and (b) above is necessary in order to have full and unrestricted rights to
such intellectual property, such intellectual property has been duly registered
with the proper authorities in Argentina. McCaw S.A. as a result of the

                  (e)      other employment contract or other compensation
agreement or arrangement, oral or written, affecting or relating to current or
former employees of WVA or any WVA Subsidiary.

        All such contracts and other agreements and arrangements set forth on

Subsidiary has performed all material obligations imposed upon it thereunder,
and there are, under any of such contracts, agreements or arrangements, no
defaults or events of default by WVA or any WVA Subsidiary or, to the knowledge
of Telcom, any other party thereto that would materially adversely affect the
business, assets or financial condition of WVA or any WVA Subsidiary, that
would materially adversely affect the relationship of WVA, any WVA Subsidiary
or MIL Argentina with any employee of WVA or any WVA Subsidiary or that could
reasonably be expected to materially adversely affect the business prospects of
WVA or any WVA Subsidiary.

        From September 30, 1996 to and including the Closing Date, neither WVA
nor any WVA Subsidiary has made any loans to any of its officers or employees
or any of the officers or employees of Telcom and its Affiliates.

<PAGE>   34




                  (a)      all material trademarks, trade names and copyrights,
including, but not limited to, "AirLink," now used by WVA or the WVA
Subsidiaries, as the case may be, and

                  (b)      all material formulae, franchises, processes,
techniques and manufacturing know-how and all trademarks, trade names and
copyrights used in connection with services now being or intended to be offered
and sold by WVA or the WVA Subsidiaries, as the case may be, except in each
case where the failure to own or have full and unrestricted rights within
Argentina to such items would not have a material adverse effect on WVA and the
WVA Subsidiaries, taken as a whole.

         Where registration of the intellectual property listed in clauses (a)
and (b) above is necessary in order to have full and unrestricted rights to
such intellectual property, such intellectual property has been duly registered
with the proper authorities in Argentina. WVA and the WVA Subsidiaries as a
result of the execution of this Agreement or the performance of their
obligations hereunder will not be deprived of any rights which they would
otherwise possess in any of the intellectual property listed in clauses (a) and
(b) above.

         A true and complete list of (i) all patents, patent applications,
patent agreements, license agreements, proprietary information agreements,
confidentiality agreements, invention agreements, consulting agreements,
trademark registrations and applications therefor, trade names, service marks
and copyright registrations and applications therefor to which WVA or any WVA
Subsidiary is a party or that are used in the operation of the WVA Business and
(ii) any interference actions or adverse claims made or threatened in respect
thereof and any claims made or threatened for alleged infringement thereof are
specifically set forth on Schedule 4.18. To the best knowledge of Telcom or
WVA, neither WVA nor any WVA Subsidiary, in its operations, infringes any valid
patent, trademark, trade name, service mark or copyright of any other Person.
Except as set forth on Schedule 4.18, all agreements listed on Schedule 4.18
are valid and enforceable, WVA and the WVA Subsidiaries have performed all
material obligations imposed upon them thereunder, and neither WVA nor any WVA
Subsidiary nor, to the knowledge of Telcom, any other party thereto is in
default thereunder in any material respect, nor is there any event that with
the giving of notice or lapse of time, or both, would constitute a material
default thereunder by WVA, any WVA Subsidiary or, to the knowledge of Telcom,
any other party thereto. Neither Telcom, WVA nor any WVA Subsidiary has
received notice that any party to any such agreement intends to cancel,
terminate or refuse to renew the same or to exercise or decline to exercise any
option or other right thereunder. Neither WVA nor any WVA Subsidiary has
entered into any agreement to indemnify any Person against any claim or charge
of infringement of any patents, trademarks, trade names, copyrights,
technology, know-how, processes or other intangible rights.

complied, and are in compliance with, all presently existing local and national
Argentine laws, rules, ordinances, decrees and orders applicable to the

or past unremedied failure by any WVA Securityholder, WVA or any WVA
Subsidiary, as the case may be, to comply with any such laws, rules,
ordinances, decrees and orders, other than actions or omissions which such WVA
Securityholder, WVA or WVA Subsidiary reasonably believes are not failures to
comply. No director, officer, agent, employee or other Person acting on behalf
of any WVA Securityholder, WVA or any WVA Subsidiary has used any funds or
given anything of value, directly or indirectly, for contributions, payments,
gifts or entertainment or made any expenditures, directly or indirectly, to any

and records accurately reflect corporate transactions and the disposition of
assets to the extent relating to the WVA Securityholders, WVA or the WVA

         Telcom agrees to indemnify and hold harmless, on an after-tax basis,
the MIL Parties, their respective successors and permitted assigns, and the
officers, directors, affiliates, employees, Controlling Persons and agents of

provided that Telcom shall not be obligated to make any payments under this

                                     -37-

<PAGE>   44


8.2      INDEMNIFICATION BY MIL

         The MIL Parties agree to indemnify and hold harmless, on an after-tax
basis, WVA, the WVA Securityholders, their successors and permitted assigns,
and the officers, directors, affiliates, employees, Controlling Persons and
agents of the foregoing and to hold each such party harmless against and in
respect of any and all Damages incurred by such party by reason of (a) breach
of any of the representations or warranties made in this Agreement by the MIL
Parties, (b) the breach of any covenant contained herein by the MIL Parties
prior to the Closing, or (c) the breach of undertakings of the MIL Parties in
any other document, supplement, instrument, agreement, letter, amendment or

provided that the MIL Parties shall not be obligated to make any payments under
this Section 8.2 unless and until the amount of Damages exceeds $100,000, after
which the MIL Parties shall be obligated to pay the entire amount of such
Damages, including the first $100,000.

8.3      PROCEDURE

         With respect to the claims made by third parties, if any of the MIL
Parties or the WVA Securityholders are threatened with any claim, or any claim
is presented to or any action or proceeding is commenced against any of the MIL
Parties or the WVA Securityholders, that may give rise to the right of
indemnification hereunder, the MIL Parties or the WVA Securityholders, as the
case may be (the "Indemnitee"), will give written notice thereof promptly (and
in no event later than the last survival date of the representation and
warranty for the breach of which indemnification is sought) to the party or
parties bearing the indemnification obligation (the "Indemnifying Party");
provided that the failure to give notice in accordance with this Section 8.3
shall not prevent enforcement hereunder if such failure is not prejudicial to
the Indemnifying Party. The Indemnifying Party shall have the right to
participate in the defense of such claim, action or proceeding, and, to the
extent the Indemnifying Party so desires, jointly with any other Indemnifying
Party similarly notified, to assume the defense thereof with counsel mutually
satisfactory to such parties and the Indemnitee, in which case every Indemnitee
shall have the right to participate through counsel of its own choosing (and
whose fees shall be paid by such Indemnitee). If the Indemnifying Party and the
Indemnitee agree upon mutually satisfactory counsel to assume the defense, the
Indemnifying Party shall assume the expense of such counsel's fees and shall no
longer assume the expense of the Indemnitee's attorneys' fees. In the event the
Indemnifying Party undertakes to compromise or defend any such liability, the
Indemnifying Party shall so notify the Indemnitee in writing promptly of its
intention to do so, and the Indemnitee shall cooperate with the Indemnifying
Party and its counsel in the compromising of or the defending against any such
liabilities or claims, at the expense of the Indemnifying Party. Such
cooperation shall include, but shall not be limited to, the provision to the
Indemnifying Party of reasonable access to the Indemnitee's business records,
research, documents and employees as they relate to the defense of any
indemnified claim. In response to a bona fide settlement offer, the
Indemnifying Party may settle the monetary portion of an indemnifiable 

                                     -38-

<PAGE>   45

matter that it has duly elected to contest without the consent of the Indemnitee
unless such settlement has an adverse effect upon the Indemnitee, in which case
such matters shall be settled only with the consent of the Indemnitee; provided,
however, that the Indemnifying Party shall not have the right to agree to a
settlement involving injunctive or other equitable relief without obtaining the
prior written consent of the Indemnitee. In the event the Indemnitee declines to
consent to the monetary settlement described in the preceding sentence, then the
Indemnitee shall have no right to indemnification beyond, and the Indemnifying
Party shall have no obligation to pay damages and attorneys' fees hereunder in
excess of, the amount of the proposed settlement.

8.4      FORM OF PAYMENT

         The Indemnifying Party may satisfy its obligations under this Article
VIII in cash or at its option in MIL Argentina Securities, based on the value
of the sum of Invested Capital divided by the number of MIL Argentina
Securities then outstanding.

8.5      SURVIVAL

         The covenants, agreements, representations and warranties made by the
parties in or pursuant to this Agreement shall survive the Closing for two
years, except as otherwise set forth herein, and except that (a) the
representations and warranties contained in Sections 3.11 and 4.11 shall
survive until expiration of the statute of limitations applicable to the
matters covered thereby (giving effect to any waiver, mitigation or extension
thereof), if later, and (b) the agreements contained in this Article VIII shall
survive indefinitely.

         delivered within 15 days after its receipt of notice pursuant to
         clause (i), to become a party to such Contract with an economic
         interest equal to the Contracting Party's economic interest under such
         Contract and voting rights, as between the Contracting Party and the
         Tag-Along Party, comparable to those set forth in the form of
         Shareholders Agreement; and

                          (iii) if either or both of MIL and Telcom would be
         required by applicable law or regulation to divest all or any portion
         of their respective Licenses or Channels as a result of the
         consummation of the transactions contemplated by the Contract, MIL and
         Telcom shall share equally in the net proceeds of such sale;

provided, further, that nothing in this Agreement shall prevent either MIL or
the WVA Securityholders from transferring their entire interests in McCaw S.A.
or the WVA Subsidiaries, respectively, to a third party at any time after the
first anniversary of the date hereof;

                  (c) by either MIL or Telcom if a court of competent
jurisdiction or governmental authority shall have issued a nonappealable final
order, decree or ruling or taken any other action, in each case having the
effect of permanently restraining, enjoining or otherwise prohibiting the
transactions contemplated hereby;

                  (d) by MIL following a breach of any representation,
warranty, covenant or agreement on the part of the WVA Securityholders or WVA
set forth in this Agreement such that the conditions set forth in Section 6.1
or 6.2 would not be satisfied; or by Telcom following a breach of any
representation, warranty, covenant or agreement on the part of the MIL Parties
set forth in this Agreement such that the conditions set forth in Section 7.1
or 7.2 would not be satisfied, which breach shall not have been cured within 20
business days following receipt by any of the MIL Parties of notice of such
breach; or

                  (e) by MIL if any representation or warranty of the WVA
Securityholders and WVA shall have become untrue such that the conditions set
forth in Article VI cannot reasonably be expected to be satisfied by the date
set forth in Section 9.1(b); or by Telcom if any representation or warranty of
the MIL Parties shall have become untrue such that the conditions set forth in
Article VII cannot reasonably be expected to be satisfied by the date set forth
in Section 9.1(b).

9.2      EFFECT OF TERMINATION

         (a) In the event of any termination pursuant to this Article IX (other
than pursuant to Section 9.1(a)), written notice setting forth the reasons
therefor shall forthwith be given by the terminating party to the other party
hereto and neither party shall have any liability to the other party of any
nature whatsoever due to such termination, except for damages resulting from a

hereof, MIL shall provide written notice to Telcom as far in advance as

authorization to use their respective Channels, to the extent feasible, located
contiguously; provided that at least 30 days prior to the Deployment Date, (i)
Telcom shall have provided to MIL evidence reasonably satisfactory to MIL that
such Channels are cleared and are not subject to any interference and (ii) all
necessary regulatory approvals relating to such exchange, if any, shall have

previous sentence shall not have been satisfied at least 30 days prior to the

McCaw S.A. Channels. The parties hereto will take all commercially reasonable
steps required to effect such exchange of channels, including, but not limited
to, making any required filings with the CNT.

                 2.3      POST-CLOSING ADJUSTMENTS

                          (a)     As promptly as practicable, but no later than
                 30 days after the Closing Date, MIL shall provide to Telcom
                 (i) a statement certifying its calculation of the MIL Holdings
                 Invested Capital and (ii) a balance sheet of McCaw S.A. as of
                 the Closing Date (the "MIL Closing Balance Sheet"), both of
                 which shall have been reviewed by McCaw S.A.'s regular
                 independent accountants, together with detailed support for
                 such calculation, and Telcom shall provide to MIL (i) a
                 statement certifying its calculation of the WVA Invested
                 Capital and (ii) a consolidated balance sheet of the WVA
                 Subsidiaries as of the Closing Date (the "WVA Closing Balance
                 Sheet," and together with the MIL Closing Balance Sheet, the
                 "Closing Balance Sheets"), both of which shall have been
                 reviewed by KPMG Peat Marwick, together with detailed support
                 for such calculation.  All calculations shall be derived from
                 the respective financial statements of McCaw S.A. and the WVA
                 Subsidiaries, which shall have been prepared in accordance
                 with U.S. generally accepted accounting principles and with
                 accounting policies and practices consistent with those used
                 in preparation of the MIL Argentina Financial Statements and
                 the WVA Financial Statements, respectively.  MIL Holdings'
                 regular independent accountants shall verify that McCaw S.A.
                 had no long-term liabilities and KPMG Peat Marwick shall
                 verify that the WVA Subsidiaries had no long-term liabilities,
                 in each case as of the Closing Date.

                          (b)     To the extent that the either party's (i)
                 Closing Balance Sheet indicates that the sum of the current
                 liabilities and long-term liabilities of such party exceeded
                 the current assets of such party as of the Closing Date by
                 more than US$1,000,000 and/or (ii) certified statement of
                 Invested Capital indicates that the amount of such party's
                 Invested Capital used for purposes of the calculations set
                 forth in Section 2.1.2(b)(iii) exceeded the amount of such
                 party's Invested Capital as of the Closing Date as shown on
                 such certified statement of Invested Capital (the aggregate
                 amount of such party's excesses being referred to herein as
                 such party's "Shortfall," and such party being referred to
                 herein as the "Deficient Party"), the Deficient Party shall,
                 subject to paragraphs (c) through (f) below, pay the JVC an
                 amount equal to the Deficient Party's Shortfall in cash within
                 15 days of the Deficient Party's delivery of its Closing
                 Balance Sheet.

                          (c)     If one party (the "Disagreeing Party")
                 disagrees with the other party's calculations described in
                 Section 2.3(b), the





                                     -6-
<PAGE>   7
                 Disagreeing Party may, within 30 days of the delivery of the
                 other party's Closing Balance Sheet, deliver a notice to the
                 other party disagreeing with such calculation and setting
                 forth its calculation.  Any such notice of disagreement shall
                 specify those items or amounts as to which the Disagreeing
                 Party disagrees, and the Disagreeing Party shall be deemed to
                 have agreed with all other items and amounts contained in the
                 other party's Closing Balance Sheet.

                          (d)     If a notice of disagreement shall be
                 delivered by a Disagreeing Party pursuant to Section 2.3(c),
                 MIL and Telcom shall, during the 15 days following such
                 delivery, use their best efforts to reach agreement on the
                 disputed items or amounts in order to determine, as may be
                 required, the amount of the other party's Shortfall, which
                 amount shall not be less than the amount thereof shown in the
                 other party's calculations delivered pursuant to Section
                 2.3(b) or more than the amount thereof shown in the
                 Disagreeing Party's calculation delivered pursuant to Section
                 2.3(c).  If, during such period, MIL and Telcom are unable to
                 reach such agreement, the MIL Parties, on the one hand, and
                 Telcom and WVA, on the other hand, shall promptly thereafter
                 cause the JVC to engage an independent accounting firm of
                 nationally recognized standing reasonably satisfactory to MIL
                 and Telcom (which shall not have any material relationship
                 with MIL or Telcom or any of their Affiliates (the
                 "Accountants")) promptly to review this Agreement and the
                 disputed items or amounts for the purpose of calculating the
                 other party's Shortfall.  The other party and its Affiliates
                 shall provide all detailed documentation necessary to support
                 the computation underlying the other party's calculation of
                 the other party's Shortfall.  In making such calculation, the
                 Accountants shall consider for change only those items or
                 amounts in the other party's Closing Balance Sheet or
                 statement of Invested Capital or the other party's calculation
                 of its own Shortfall as to which the Disagreeing Party has
                 disagreed.  The Accountants shall deliver to MIL and Telcom,
                 as promptly as practicable, a report setting forth such
                 calculation.  Such report shall be final and binding upon MIL
                 and Telcom.  The cost of such review and report shall be borne
                 (i) by the Disagreeing Party if the difference between the
                 Accountants' calculation of the other party's Shortfall and
                 the Disagreeing Party's calculation of the other party's
                 Shortfall delivered pursuant to Section 2.3(c) is greater than
                 the difference between the Accountants' calculation of the
                 other party's Shortfall and the other party's calculation of
                 the other party's Shortfall delivered pursuant to Section
                 2.3(b), (ii) by the other party if the




                                     -7-
<PAGE>   8

                 first such difference is less than the second such difference,
                 and (iii) otherwise equally by MIL and Telcom.

                          (e)     If the Accountants shall have calculated
                 MIL's or Telcom's Shortfall, MIL or Telcom, as the case may
                 be, agrees to pay the JVC the amount of any Shortfall, as
                 calculated by the Accountants pursuant to Section 2.3(d), in
                 cash within ten days of receipt of the Accountants'
                 calculation, to the extent such payment has not already been
                 made pursuant to Section 2.3(b).  Any Shortfall may be
                 satisfied, at the option of the party having an obligation to
                 pay a Shortfall, by payment of cash to the JVC or by the
                 exercise of the option to require the Company to repurchase
                 shares of the Company's share capital pursuant to Section 6 of
                 the Members Agreement.

                          (f)     MIL and Telcom agree that they will, and
                 agree to cause their respective independent accountants, MIL
                 Holdings, MIL Argentina, McCaw S.A., WVA and the WVA
                 Subsidiaries to, cooperate and assist in the Accountants'
                 review of the Closing Balance Sheets, including, without
                 limitation, the making available to the extent necessary of
                 books, records, work papers and personnel.

         (c)     Section 3.7 of the Agreement is hereby amended and restated to
read in its entirety as follows:

                 leases, subleases, rental agreements, contracts of sale or
                 licenses of any portion of the personal property (the "WVA
                 Personal Property") owned, leased or rented by the WVA
                 Subsidiaries.  The WVA Subsidiaries have legal ownership or
                 other legal rights to use all property used in the conduct of
                 the WVA Business as presently conducted.  Schedule 4.12(a)
                 lists all leased WVA Personal Property with a monthly lease
                 payment (or annual lease payment prorated on a monthly basis)

                 (d)      Except as listed on Schedule 4.12(d), the WVA Assets
                 are free and clear of all Liens (other than Permitted Liens),
                 and, other than leased WVA Assets, each of the WVA
                 Subsidiaries has good and marketable title thereto.  The WVA
                 Subsidiaries have valid leasehold interests in all leased
                 assets.

                 (g)      No assets used by the WVA Subsidiaries are owned by
                 any Affiliate of the WVA Subsidiaries (excluding the WVA
                 Subsidiaries).

         (l)     Section 4.15 of the Agreement is hereby amended and restated
to read in its entirety as follows:

                 Telcom has provided or will provide MIL prior to the Closing
                 Date a copy of, and has made available or will make available
                 for review by MIL prior to the Closing Date originals of, all
                 material contracts, oral or written, to which the WVA
                 Subsidiaries are a party,

                 including, without limitation, security agreements,
                 conditional sale agreements and instruments relating to the
                 borrowing of money and all material contracts to which WVA is
                 a party that directly relate to the WVA Business or the WVA
                 Assets.  Schedule 4.15 lists all such contracts.  All such
                 contracts are valid and in full force and effect, each of WVA
                 and the WVA Subsidiaries, as the case may be, has performed
                 all material obligations imposed upon it thereunder, and there
                 are, under any of such contracts, no defaults or events of
                 default by WVA or any WVA Subsidiary, as the case may be, or,
                 to the knowledge of Telcom, or any other party thereto, that
                 would materially adversely affect the business, assets or
                 financial condition of the WVA Subsidiaries, taken as a whole,
                 or which could reasonably be expected to materially adversely
                 affect the business prospects of the WVA Subsidiaries, taken
                 as a whole.  None of the WVA Securityholders, WVA or any WVA
                 Subsidiary has received notice, nor is any WVA Securityholder,
                 WVA or any WVA Subsidiary otherwise aware, that any party to
                 any such contract intends to cancel, terminate or refuse to
                 renew such contract or to exercise or decline to exercise any
                 option or right thereunder.


         (m)     Section 4.16 of the Agreement is hereby amended and restated
to read in its entirety as follows:

                 Except as described on Schedule 4.16, there are no claims
                 pending or, to the knowledge of the WVA Securityholders, WVA
                 or any WVA Subsidiary, threatened against any WVA
                 Securityholder, WVA or any WVA Subsidiary with respect to the
                 WVA Business, before or by any governmental or nongovernmental
                 department, commission, board, bureau, agency, instrumentality
                 or any other Person, which Claims are reasonably likely to be
                 resolved adversely to any of the WVA Securityholders, WVA or
                 any of the WVA Subsidiaries, and which if so resolved would
                 have a material adverse effect on the WVA Subsidiaries, taken
                 as a whole.  There are no outstanding or unsatisfied
                 judgments, orders, decrees or stipulations to which any WVA
                 Securityholder, WVA or any WVA Subsidiary is a party that
                 involve the transactions contemplated hereby or that could
                 individually or in the aggregate have a material adverse
                 effect upon the business, assets, financial condition or
                 business prospects of the WVA Subsidiaries, taken as a whole.

         (n)     The first two paragraphs and the first sentence of the third
paragraph of Section 4.18 of the Agreement are hereby amended and restated to

                 The WVA Subsidiaries own, or have full and unrestricted rights
                 within Argentina (to the extent available under Argentine law)
                 to:

                          (a)     all material trademarks, trade names and
                 copyrights, including, but not limited to, "AirLink," now used
                 by the WVA Subsidiaries, and

                          (b)     all material formulae, franchises, processes,
                 techniques and manufacturing know-how and all trademarks,
                 trade names and copyrights used in connection with services
                 now being or intended to be offered and sold by the WVA
                 Subsidiaries, as the case may be, except in each case where
                 the failure to own or have full and unrestricted rights within
                 Argentina to such items would not have a material adverse
                 effect on the WVA Subsidiaries, taken as a whole.

                 Where registration of the intellectual property listed in
                 clauses (a) and (b) above is necessary in order to have full
                 and unrestricted rights to such intellectual property, such
                 intellectual property has been duly registered with the proper
                 authorities in Argentina.  The WVA Subsidiaries as a result of
                 the execution of this Agreement or the performance of their
                 obligations hereunder will not be deprived of any rights which
                 the WVA Subsidiaries would otherwise possess in any of the
                 intellectual property listed in clauses (a) and (b) above.

                 A true and complete list of (i) all patents, patent
                 applications, patent agreements, license agreements,
                 proprietary information agreements, confidentiality
                 agreements, invention agreements, consulting agreements,
                 trademark registrations and applications therefor, trade
                 names, service marks and copyright registrations and
                 applications therefor to which any WVA Subsidiary is a party
                 or that are used in the operation of the WVA Business and (ii)
                 any interference actions or adverse claims made or threatened
                 in respect thereof and any claims made or threatened for
                 alleged infringement thereof are specifically set forth on
                 Schedule 4.18.

         (o)     The second sentence of Section 4.20 of the Agreement is hereby
amended and restated to read in its entirety as follows:

                 Except where noncompliance would not individually or in the
                 aggregate have a material adverse effect on the WVA
                 Subsidiaries, taken as a whole, the WVA Securityholders, WVA
                 and the WVA Subsidiaries have complied, and are in compliance
                 with, all presently existing local and national Argentine
                 laws, rules,

                 delivered by Telcom or any officer thereof to any MIL Party,
                 and each such certificate shall be deemed to be a
                 representation by the WVA Securityholders as to the matters
                 set forth therein.  All representations and warranties herein

                 which were incurred by reason of the matters described in

                 remedied by the indemnification of the JVC pursuant to this
                 Section 8.1.

                 8.2      INDEMNIFICATION BY MIL

                          Subject to and in accordance with Section 8.4, the

                 unless and until the amount of Damages exceeds US$100,000,
                 after which the MIL Parties, jointly and severally, shall be

                 8.3      PROCEDURE

                          Promptly after receipt by any indemnified party of
                 notice of any claim, action or proceeding which may give rise
                 to a right of indemnification hereunder, such indemnified
                 party (the "Indemnitee") will give written notice thereof (the
                 "Claim Notice") promptly (and, if the matter for which the
                 Indemnitee is seeking indemnification hereunder arises from a
                 breach of a representation and warranty, in no event later
                 than the last survival date of the representation and warranty
                 for the breach of which indemnification is sought) to the
                 party or parties bearing the indemnification obligation (the
                 "Indemnifying Party"); provided that the failure to give
                 notice in accordance with this Section 8.3 shall not prevent
                 enforcement hereunder if such failure is not prejudicial to
                 the Indemnifying Party.  If any of the MIL Parties believes
                 that the JVC has a right of indemnification hereunder from
                 Telcom or WVA, or if Telcom or WVA believes that the JVC has a
                 right of indemnification hereunder from any of the MIL
                 Parties, then the MIL Parties, Telcom and WVA shall cause the
                 JVC to take all action necessary to enforce such right.  The
                 Indemnifying Party shall have the right to participate in the
                 defense of any claim, action or proceeding which may give rise
                 to a right of indemnification hereunder, and, to the extent
                 the Indemnifying Party so desires, jointly with any other
                 Indemnifying Party similarly notified, to assume the defense
                 thereof with counsel mutually satisfactory to such parties and
                 the Indemnitee, in which case every Indemnitee shall have the
                 right to participate through counsel of its own choosing (and
                 whose fees shall be paid by such Indemnitee).  If the
                 Indemnifying Party and the Indemnitee agree upon mutually
                 satisfactory counsel to assume the defense, the Indemnifying
                 Party shall assume the reasonable fees and expenses of such
                 counsel and shall no longer assume the fees and expenses of
                 any other attorney representing the Indemnitee.  If the
                 Indemnifying Party undertakes to compromise or defend any such
                 liability, the Indemnifying Party shall so notify the
                 Indemnitee in writing promptly of its intention to do so, and
                 the Indemnitee shall cooperate with the Indemnifying Party and
                 its counsel in the compromising of or the defending against
                 any such liabilities or claims, at the expense of the
                 Indemnifying Party.  Such cooperation shall include, but shall
                 not be limited to, the provision to the Indemnifying Party of
                 reasonable access to the Indemnitee's business records,
                 research, documents and employees as they relate to the
                 defense of any indemnified claim.  In response to a bona fide
                 settlement offer, the Indemnifying Party may settle the
                 monetary portion of an indemnifiable matter without the
                 consent of the Indemnitee provided that such settlement





                                    -19-
<PAGE>   20
                 (i) includes as an unconditional term thereof the giving by
                 the plaintiff or claimant to the Indemnitee of a release from
                 all liability in respect of such claim or litigation, (ii)
                 provides that the Indemnitee does not admit any guilt or fault
                 with respect to the subject matter of such claim or
                 litigation, and (iii) does not involve injunctive or other
                 equitable relief.

         (ff)    Section 8.4 of the Agreement is hereby amended and restated to
read in its entirety as follows:

                 8.4      METHOD OF PAYMENT

                          The Indemnifying Party may satisfy its obligations
                 under this Article VIII in cash or at its option in shares in
                 the share capital of the JVC at their Appraised Fair Market
                 Value (as defined below).  The Indemnifying Party and the
                 Indemnitees agree that in any case of indemnification
                 hereunder where the JVC is damaged, payment will be made to
                 the JVC; provided, however, that to the extent any Indemnitee
                 is not made whole by such payment, such Indemnitee shall still
                 retain a right to indemnification under this Section 8.

                          For purposes of this Agreement, "Fair Market Value"
                 of any of the share capital of the JVC means the price that an
                 unrelated third party would pay if it were to acquire all
                 outstanding equity interests of the JVC on the date the Claim
                 Notice is deemed to be received by the Indemnifying Party in
                 an arm's-length transaction, assuming that such equity
                 interests were being sold in a manner designed to attract all
                 possible participants and without taking into consideration a
                 control premium or minority discount, multiplied by the
                 percentage of the aggregate share capital represented by the
                 amount of share capital in question on a fully-diluted basis.
                 The "Appraised Fair Market Value" shall be determined in
                 accordance with the following procedures:  the Indemnifying
                 Party shall select an investment banking firm of recognized
                 national standing (the "First Appraiser"), which shall
                 appraise the Fair Market Value and deliver its appraisal to
                 the JVC, every Indemnitee and the Indemnifying Party, within
                 60 days of its engagement.  If the Indemnitees (represented by
                 one Person designated by the mutual consent of the Indemnitees
                 (the "Representative")) shall disagree with the Fair Market
                 Value determined by such appraiser, then the Representative
                 shall have the right to appoint an additional investment
                 banking firm of recognized national standing (the "Second
                 Appraiser").  If the Representative does not engage a Second
                 Appraiser within 30 days of the First





                                    -20-
<PAGE>   21
                 Appraiser's delivery of its appraisal, the First Appraiser's
                 appraisal shall be the Appraised Fair Market Value.  If the
                 Representative engages a Second Appraiser, the Second
                 Appraiser will appraise the Fair Market Value, and deliver its
                 appraisal to the JVC, the Indemnitees and the Indemnifying
                 Party, within 60 days of its engagement.  If the difference
                 between the two appraisals is less than 20% of the lower
                 appraised value, then the Appraised Fair Market Value shall be
                 the average of the two appraisals.  If such difference is
                 greater than or equal to 20% of the lower appraised value, the
                 two appraisers shall engage a third independent investment
                 banking firm of recognized national standing (the "Third
                 Appraiser"), which shall appraise the Fair Market Value within
                 60 days of its engagement.  The Appraised Fair Market Value
                 shall be the average of the two appraised values that are
                 closest in absolute U.S. dollars.  All appraisals of Fair
                 Market Value shall be as of the date of notice of exercise of
                 the right.  The expenses of the First Appraiser shall be borne
                 by the Indemnifying Party; the expenses of the Second
                 Appraiser, if any, shall be borne by the Indemnitees, jointly
                 and severally; and the expenses of the Third Appraiser, if
                 any, shall be borne equally by the Indemnifying Party on the
                 one hand and the Indemnitees, jointly and severally among
                 themselves, on the other hand.

         (gg)    The following Section 8.5 is hereby inserted at the end of
Article VIII of the Agreement:

                 8.5      THIRD PARTY BENEFICIARY

                          The JVC is intended to be a third party beneficiary
                 of (i) the representations, warranties and covenants in this
                 Agreement of each of Telcom, WVA and the MIL Parties and (ii)
                 the undertakings of each of Telcom, WVA and the MIL Parties in
                 any other document, supplement, instrument, agreement, letter,
                 amendment or assignment executed in connection herewith or in
                 any officers' certificate delivered to the JVC, Telcom or its
                 Affiliates or MIL or its Affiliates at or in connection with
                 the Closing.  As such, the JVC shall be entitled to enforce
                 any such representation, warranty, covenant or undertaking as
                 if it were a party to this Agreement, and the JVC shall be
                 entitled to seek indemnification for, and to recover any
                 damages suffered by it, in respect of any breach of any such
                 representation, warranty, covenant or undertaking, including
                 without limitation, recovery for any breach that results in
                 the value of the JVC as of the Closing Date being less than
                 the sum of the MIL Holdings Invested Capital and the WVA
                 Invested Capital.

         (hh)    The following new Article X is inserted after Article IX and
the former Article X is renumbered to be Article XI and Sections 10.1 to 10.9
are renumbered to be Sections 11.1 to 11.9.

                                   ARTICLE X

                                 NONCOMPETITION

                 10.1     NONCOMPETITION

                          Each of MIL and Telcom agree that, until one year
                 following termination of the Members Agreement with respect to
                 all Affiliates Controlled by such party, neither such party
                 nor any Affiliate Controlled by such party shall in any way,
                 by action or inaction, directly or indirectly, for itself or
                 for the benefit of any other Person, own, manage, operate,
                 join, Control or participate in the ownership, management,
                 operation or Control of any Person that competes with the JVC
                 or any Affiliate thereof, or agrees to do any of the
                 foregoing, in the business of paging or SMR in Argentina,
                 other than wireless radio engineering, design or program
                 management services and the manufacture and sale of related
                 software and hardware products.  In addition, neither any
                 party nor any Affiliate Controlled by such party may maintain
                 an equity interest in any Person (other than the JVC) in which
                 it owns an equity interest as of the date hereof, which equity
                 interest entitles any such party or any Affiliate Controlled
                 by such party to control of policymaking or day-to-day
                 operations of such Person or in connection with which any such

                 representative on the board of directors, if such Person
                 elects to engage in the business of cellular communications or
                 Personal Communications Systems in Argentina.

                 10.2     SPECIFIC PERFORMANCE

                 The parties hereto acknowledge that it may be impossible to
                 measure in money the damages that any party may incur as a
                 result of another party's violation of any provision of this
                 Article X.  Consequently, in any action specifically to
                 enforce any provision of this Agreement, each party hereby
                 waives any claim or defense therein that an adequate remedy at
                 law or in damages exists.  Each party further agrees that the
                 other parties shall be entitled to injunctive relief, specific
                 performance or other equitable relief to prevent violation of
                 any provision of this Agreement.

         (ii)    Renumbered Section 11.1 of the Agreement is hereby amended and

SECTION 2.       ACQUISITIONS BY THE NEXTEL GROUP

         2.1     [Intentionally Omitted]

         2.2     [Intentionally Omitted].

         2.3     Nextel's First Merger Right.  (a) In the event (i) a proposal
for a tender or exchange offer to acquire a majority of the outstanding Voting
Securities or to effect a Business Combination of the Company has been
presented to the Company by a Person other than Nextel or any of its Affiliates
(a "Third Party Merger Proposal"), (ii) the Board of Directors is considering,
and has not rejected, such proposal and (iii) the Fully Diluted Ownership
Percentage of Nextel and its Qualified Affiliates is at least 20%, then the
Company shall give Nextel prompt written notice of such Third Party Merger
Proposal.  If such Third Party Merger Proposal provides for non-cash
consideration that can reasonably be given a fair cash value by an investment
banking firm of national standing in the United States or Mexico (a "Fair Cash
Value"), then the Company shall promptly engage an investment banking firm to
determine the Fair Cash Value of the Third Party Merger Proposal.  Such
investment banking firm shall be selected by a Majority Vote of the
Disinterested Directors from a list of four nominees proposed by Nextel from
the list of investment banks set forth on Annex D; provided that if Nextel does
not submit to the Company a list of four nominees from Annex D within five days
of notice to Nextel of the Third Party Merger Proposal, then the Disinterested
Directors shall be free to select any investment bank listed on Annex D.  If,
on or prior to the later of the fifth day after notice from the Company of the
Fair Cash Value of the Third Party Merger Proposal (as determined by the
investment banking firm engaged by the Company) and the twentieth day following
notice to Nextel of the Third Party Merger Proposal, Nextel shall have
submitted to the Board of Directors an alternative proposal providing for (x) a
Fair Cash Value equal to or greater than the Third Party Merger Proposal
(provided that this condition shall not be satisfied if the investment banking
firm engaged by the Company has advised the Board that, in its opinion, the
Fair Cash





                                       14
<PAGE>   18
Value of the Third Party Merger proposal is greater than the Fair Cash Value of
the Nextel proposal) and (y) all other terms and conditions are substantially
comparable to those of the Third Party Merger Proposal (it being understood
that Nextel shall not be required, in order to satisfy this condition, to
submit an alternative proposal providing for a closing of the proposed
transaction prior to the ninetieth day after the submission of the Third Party
Merger Proposal), then (unless the alternative offer made by Nextel expires or
is otherwise terminated or the transactions contemplated thereby fail to be
consummated in accordance with the terms thereof as a result of any action or
omission by a member of the Nextel Group) each Principal Shareholder (i) shall
not permit any of its Nominees to vote to accept or recommend approval of such
Third Party Merger Proposal and (ii) may (but shall not be required to) cause
each of its Nominees to vote to accept or recommend approval of Nextel's
proposal.  Each Principal Shareholder shall vote against, shall take whatever
action is reasonably necessary in respect of the Control Trust  to cause the
Voting Securities related to its Beneficiary Rights therein to be voted against
and shall not permit any of its Nominees to vote to accept or recommend,
approval of any resolution, process, procedure, requirement or other action
considered by the Board of Directors or any committee thereof with respect to
any Third Party Merger Proposal that provides the Person that has made a Third
Party Merger Proposal with any information regarding, or access to, or any
direct or indirect payment of any expense or conferral of any break-up fee or
lock-up option in any auction or bidding process from, the Company in
connection with such Third Party Merger Proposal that is not also available to
Nextel; provided, however, that any Principal Shareholder may vote for, may
take whatever action is necessary in respect of the Control Trust to cause the
Voting Securities underlying its Beneficiary Rights therein to be voted for and
may permit any of its Nominees to vote to accept or recommend any such
resolution, process, procedure or requirement in the event that (A) Nextel has
not satisfied the conditions set forth in clauses (x) and (y) above on or prior
to the later of the fifth day after notice from the Company of the Fair Cash
Value of the Third Party Merger Proposal (as determined by the investment
banking firm engaged by the Company) and the twentieth day following notice to
Nextel of the Third Party Merger Proposal or (B) the alternative offer made by
Nextel expires or is otherwise terminated or the transactions contemplated
thereby fail to be consummated in accordance with the terms thereof as a result
of any action or omission by a member of the Nextel Group.

         (b)  In the event that the Board accepts or recommends a Third Party
Merger Proposal in accordance with this Section 2.3 and such Third Party Merger
Proposal does not close within one year of the date of such acceptance or
recommendation, then such Third Party Merger Proposal shall be subject to
compliance again with the provisions of this Section 2.3.





                                       15
<PAGE>   19
         (c)  In the event that Nextel submits an alternative proposal pursuant
to Section 2.3(a), each Principal Shareholder shall cause its Nominees to
extend reasonable cooperation to Nextel in connection with the review and
evaluation of such proposal.

         (d)  Nothing in this Section 2.3 shall be construed to preclude the
Board of Directors from soliciting or considering proposals from Persons other
than Nextel or any of its Affiliates (including new or modified proposals from
any Person that has made a Third Party Merger Proposal) in addition or as
alternatives to a Third Party Merger Proposal or any proposal made by Nextel or
any of its Affiliates pursuant to this Section 2.3 or otherwise (provided that
the Company shall comply with the provisions of this Section 2.3 with respect
to any such new or modified proposal that is a Third Party Merger Proposal).
Notwithstanding any other provisions of subsections (a), (b) and (c) of this
Section 2.3, any member of the Board of Directors may take any actions that
such member determines in good faith, based on the advice of legal counsel, to
be legally required, and no Principal Shareholder shall be in breach of this
Section as a result of any such actions.

SECTION 3.       TREASURY SHARES; PREEMPTIVE RIGHTS

         3.1     Agreement to Issue Treasury Shares.  Each of the Original
Shareholder Parties and Nextel Investment hereby consents to the issuance of
508,492 Shares of N$1,000 par value (made pursuant to a shareholders'
resolution attached hereto in Annex G) to be held in the treasury of the
Company for the purpose of subsequent resale in one or more public offerings or
private placements (the "Treasury Stock") (it being understood that such
consent to the issuance into treasury does not extend to subsequent transfers
of such shares by the Company except as provided herein).  Each of the Original
Shareholder Parties and Nextel Investment hereby waives (and shall cause each
of its Affiliates to waive) any pre-emptive rights it has with respect to the
issuance of the Treasury Stock, whether arising under the Estatutos, Mexican
law or otherwise.  Each of the Original Shareholder Parties and Nextel
Investment agrees to take (and to cause its Affiliates to take) such actions,
including, without limitation, any actions in respect of the Control Trust, as
are necessary or reasonably requested by the Company to effect such issuance of
Treasury Stock into the treasury of the Company and waiver of pre-emptive
rights.

         3.2     Certain Antidilution Rights.  (a)  Notwithstanding Section
3.1, in the event that the Company transfers any Shares of the Treasury Stock
or any rights, warrants or options to acquire, Shares of Treasury Stock (any
such Shares, rights, warrants or options being "Treasury Securities" and any
such transfer being a "Market Issuance"), the Company shall provide each
Principal Shareholder Group with a Fully Diluted Ownership Percentage of at
least 10% (an "Antidilution Purchaser") the





                                       16
<PAGE>   20
right to acquire a number of Shares, rights, warrants or options to acquire
Shares (corresponding to the form of the Treasury Securities) of Treasury Stock
(the "Antidilution Securities"), equal to the sum of (x) the product of (i) the
number of Treasury Securities being transferred in the Market Issuance
multiplied by (ii) the percentage of outstanding Shares of the Company owned by
such Antidilution Purchaser as of a date (the "Calculation Date") occurring 10
Business Days prior to the earlier of (A) the date of the notice by the Company
of the Antidilution Exercise Date referred to below and (B) the closing date of
the Market Issuance plus (y) such additional amount of Shares as will result in
such Antidilution Purchaser owning, after giving effect to the Market Issuance
and the delivery of Shares to all Antidilution Purchasers in connection with
the exercise of antidilution rights under this Section, a percentage of such
Treasury Securities and all such additional Shares delivered pursuant to this
Section equal to the percentage of outstanding shares owned by such
Antidilution Purchaser on the Calculation Date.  Notwithstanding the foregoing,
the term "Treasury Securities" shall not include the Revised Option Shares, the
Three Year Option Shares, Shares issued under the employee stock option plan in
effect as of the date hereof or Shares issued under the Subscription Agreement.

         (b)  In order to exercise its right under this Section 3.2 to acquire
a number of Antidilution Securities as specified in Section 3.2(a) hereof each
Antidilution Purchaser must:  (i) on or prior to the Antidilution Exercise Date
(as defined below) provide a written undertaking to the Company, accompanied by
such guaranties and/or collateral as the Company may reasonably require, to
purchase all or any portion (expressed as a percentage) of the Antidilution
Securities to which such Antidilution Purchaser will have the right to purchase
under Section 3.2(a) hereof at the same purchase price, at which, and on the
other terms and conditions (except for the timing of closing or otherwise as
provided in this Section 3.2) pursuant to which, such Treasury Securities are
initially sold to the underwriter(s) or, in the case of a private placement, to
the initial purchaser(s); and (ii) comply with any restrictions on resale or
other transfer of such Antidilution Securities and such other terms and
conditions in respect of the purchase of such Antidilution Securities, as shall
be reasonably requested by the Company and/or, in the case of a public
offering, the managing underwriter(s) or, in the case of a private placement,
the manager(s) for the initial purchaser(s).  As used herein, "Antidilution
Exercise Date" means a date selected by the Company and notified to each
Antidilution Purchaser on at least five Business Days' written notice, which
notice shall be given not earlier than the date of the pricing of the Market
Issuance and not later than the closing of the Market Issuance.  Any such
notice of the Antidilution Exercise Date shall also include the type and number
of Treasury Securities included in the Market Issuance, the terms and
conditions of the Market Issuance and the number of Antidilution Securities the
Antidilution Purchaser would be entitled to purchase under this Section 3.2.





                                       17
<PAGE>   21
         (c)  The closing for the purchase of Antidilution Securities by any
Antidilution Purchaser exercising its rights under this Section 3.2 shall occur
on the closing date of such Market Issuance or on such later date selected by
the Company on at least five Business Days' notice to the Antidilution
Purchasers provided that such date is not earlier than the closing date of the
Market Issuance and not more than five Business Days following the closing date
of the Market Issuance; it being understood that the closing of the purchase of
the Antidilution Securities may occur on the Antidilution Exercise Date.  Such
closing shall occur in the Company's principal offices in Mexico City or at
such other place or on such other date as to which the Company and such
Antidilution Purchaser may mutually agree.  In connection with such closing,
the Company and such Antidilution Purchaser shall deliver to each other such
customary closing certificates and legal opinions as may be reasonably
requested by such other party.

         3.3     Notice of Estatutos Pre-Emptive Rights.  At least fifteen days
prior to each deadline for the exercise of pre-emptive rights under Article
Seven of the Company's Estatutos, the Company shall provide each Original
Shareholder Party with notice of such Principal Shareholder's opportunity to
exercise its pre-emptive right under Article Seven of the Company's Estatutos
and any other information relevant to such opportunity to exercise pre-emptive
rights that, pursuant to such Article Seven, the Company has either published
in the Diario Oficial de la Federacion and in a newspaper of general
circulation in the Company's domicile or announced at a shareholders meeting at
which all of the Shares representing the capital stock of the Company were
represented; provided, however, that in the event the Company receives a
written opinion from counsel experienced in such matters that provision of such
notice would violate applicable Requirements of Law, the Company shall be
released from its obligations to provide such notice hereunder.

SECTION 4.       REGISTRATION RIGHTS

         The Principal Shareholders shall have the registration rights set
forth in Annex A, subject to the requirement that all transfers be made in

with respect to any vote or other action taken by such board of directors (or
similar governing body) or committee thereof on any matter specified in clauses

power to control Natel's book and record keeping, Natel's) conduct of business
in such country may be maintained in the official language of such country.
Each Director and Principal Shareholder Group shall be permitted to bring an

to the reporting requirements of the Exchange Act, the Company shall maintain
and make available to each Principal Shareholder all books, records, accounts
and reports required by (and compiled in accordance with) applicable Exchange
Act reporting requirements.

         such financial year) other than the last such three-month period of
         such financial year, copies of the consolidated and consolidating
         financial statements of the Company and its Subsidiaries (and, prior

<PAGE>   26
unreasonable effort or expense by the Company (it being understood that after

Company becomes subject to the reporting requirements of the Exchange Act, such
information would include, without limitation, financial information concerning
the Company conformed to U.S. GAAP standards), and shall certify to Nextel and

         (a)     If, at any time following the occurrence of a Change of Control
Date and prior to the termination of the Control Trust, Nextel would, but for
the occurrence of such Change of Control Date, be entitled to designate at least
one representative on the Technology Committee pursuant to Section 12 of the
Control Trust, the Company shall not make any technology decision relating to
the Company's digital mobile systems including, without limitation, technology
decisions related to vendor selection, build-out and system design, without the
consent of Nextel, such consent not to be unreasonably withheld. Notwithstanding
the foregoing, no such consent shall be required if the decision involves (i)
the selection of any mobile communications technology when one of the
alternatives under consideration is a Proprietary Technology (as defined below)
of Nextel or a Majority Affiliate (each being a "Nextel Supplier") or (ii) the
selection of a manufacturer of any mobile communications equipment when one of
the manufacturers under consideration is a Nextel Supplier; provided that the
foregoing consent right shall be reinstated at any time that all Nextel
Suppliers have been eliminated from consideration.  As used herein, "Proprietary
Technology" means any technology (or component or embodiment thereof) that is
not made generally available by license or otherwise to manufacturers of
telecommunications equipment.

         (b)     After the termination of the Control Trust and so long as (i)
the Control Trust Modification Date has not occurred, (ii) Nextel and its
Qualified Affiliates Beneficially Own at least 10% of the Outstanding Voting
Securities and (iii) WVM has not waived its rights under Section 5.9 hereof, no
Principal Shareholder shall vote at a shareholders meeting or permit any of its
Nominees to vote at a Board of Directors meeting to approve any technology
decisions relating to the Company's digital mobile systems, including, without
limitation, technology decisions related to vendor selection, build-out and
system design, without the consent of Nextel, such consent not to be
unreasonably withheld.  Notwithstanding the foregoing, no consent shall be
required if the decision involves (A) the selection of any mobile communications
technology when one of the alternatives under consideration is a Proprietary
Technology of a Nextel Supplier or (B) the selection of a manufacturer of any
mobile communications equipment when one of the manufacturers under
consideration is a Nextel Supplier (provided that the foregoing consent right
shall be reinstated at any time that all Nextel Suppliers have been eliminated
from consideration).

         (c)  Notwithstanding the provisions of Sections 5.8(a) and 5.8(b)
hereof, any Principal Shareholder or member of the Board of Directors may take
any action that it determines in good faith, based on the advice of legal
counsel, to be legally required, and no Principal Shareholder shall be in
breach of Section 5.8(a) or 5.8(b) hereof as a result of such action.

         5.9     WVM's Technology Consent.  After the termination of the
Control Trust and so long as WVM and its Qualified Affiliates Beneficially Own

shall vote at a shareholders meeting or permit any of its Nominees to vote at a
Board of Directors meeting to approve any technology decisions relating to the
Company's digital mobile systems, including, without limitation, technology
decisions related to vendor selection, build-out and system design, without the
consent of WVM, such consent not to be unreasonably withheld.  Notwithstanding
the foregoing, (i) no consent shall be required if the decision involves (a)
the selection of any mobile communications technology when one of the
alternatives under consideration is a Proprietary Technology of a member of the
WVM Group (a "WVM Supplier") or (b) the selection of a manufacturer of any
mobile communications equipment when one of the manufacturers under
consideration is a WVM Supplier (provided that the foregoing consent right
shall be reinstated at any time that all WVM Suppliers have been eliminated
from consideration) and (ii) any Principal Shareholder or member of the Board
of Directors may take any action that it determines in good faith, based on the
advice of legal counsel, to be legally required, and no Principal Shareholder
shall be in breach of this Section 5.9 as a result of such action.

         5.10    Business Plans.  A Shareholders meeting or a Board meeting of
the Company shall be held annually at which a vote will be taken on the
adoption of a new business plan for the Company.

         5.11    Transfer of Beneficial Ownership of Voting Securities.

         (a)     Notwithstanding anything to the contrary in this Agreement or
the Control Trust Agreement, the parties hereto hereby agree that the transfer
of Beneficial Ownership of Voting Securities by Grupo to the Mexican
Individuals shall not be subject to any provision of this Agreement or the
Control Trust Agreement, provided, that such transfer to the Mexican
Individuals consists solely of Voting Securities that are in turn transferred
immediately by the Mexican Individuals to Nextel Investment under the terms and
conditions of the Share Purchase and Call Option Agreement.

         (b)     Notwithstanding anything to the contrary in this Agreement or
the Control Trust Agreement, the parties hereto hereby agree that the
redemption by the Company of Voting Securities Beneficially Owned by Grupo
pursuant to the resolutions attached hereto as Annex G shall not be subject to
any provision of this Agreement or the Control Trust Agreement.

own expenses, including the fees and expenses of any attorneys, accountants,
investment bankers, brokers, finders or other intermediaries or other Persons

agreements contemplated hereby.

         7.3     Benefits; Assignment.  (a)  The provisions of this Agreement
shall be binding upon, and inure to the benefit of the Parties.  Nothing in
this Agreement, express or implied, is intended to confer upon any Person
(other than the Parties) any rights, remedies or obligations under or by reason
of this Agreement.

         (b)     None of the Principal Shareholders or the Company shall assign
or delegate any of its rights or obligations hereunder or any interest herein
without obtaining the written consent of each of the Principal Shareholders and
the Company and any purported assignment or delegation made without obtaining
such written consent shall be null and void; provided, that the foregoing shall
not be deemed to prevent assignments to other members of a Principal
Shareholder's Principal Shareholder Group and assignments pursuant to Section
A.15 of Annex A hereto, each of which are expressly permitted hereunder.
Notwithstanding the foregoing Nextel may assign and transfer its rights and
obligations hereunder, without the consent of the other Parties, in connection

other Person being herein referred to as the "New Person"), provided that the

deemed to refer to the New Person.

includes the Annexes hereto), the Amendment, dated as of the date hereof, among
each of the Parties hereto and Banco del Atlantico, S.A. and the Control Trust
Agreement constitute the entire agreement among the Parties with respect to the
subject matter hereof and thereof and supersede all prior agreements and
understandings, both written and oral, among the Parties with respect to the
subject matter hereof and thereof.  This Agreement may not be amended,
supplemented or otherwise modified except by an instrument in writing signed by
each of the Parties.  No waiver by any Party of any of the provisions hereof
shall be effective unless explicitly set forth in writing and executed by such
Person.  Any waiver of a breach of this Agreement by any Party shall not
operate or be construed as a waiver by such Party of any subsequent breach.

         7.5     Headings.  The headings in this Agreement are for convenience
only and shall not affect the construction hereof.

         7.6     Governing Law.  THE VALIDITY, CONSTRUCTION, ENFORCEABILITY AND
INTERPRETATION OF THIS AGREEMENT (OTHER THAN THE PROVISIONS OF ANNEX A) SHALL
BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF MEXICO, WITHOUT
GIVING EFFECT TO ANY CHOICE OF LAW OR CONFLICT OF LAW PROVISION OR RULE
(WHETHER OF MEXICO OR ANY OTHER JURISDICTION) THAT WOULD CAUSE THE APPLICATION
OF THE LAWS OF ANY JURISDICTION OTHER THAN THE LAWS OF MEXICO.  THE VALIDITY,
CONSTRUCTION, ENFORCEABILITY AND INTERPRETATION OF THE PROVISIONS OF ANNEX A
SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE
OF NEW YORK, UNITED STATES OF AMERICA, WITHOUT GIVING EFFECT TO ANY CHOICE OF
LAW OR CONFLICT OF LAW PROVISION OR RULE (WHETHER OF NEW YORK OR ANY OTHER
JURISDICTION) THAT WOULD CAUSE THE APPLICATION OF THE LAWS OF ANY JURISDICTION
OTHER THAN THE LAWS OF NEW YORK.

         7.7     Arbitration.  (a)  Except for obtaining a temporary
restraining order or preliminary injunction to prevent immediate irreparable
harm, any controversy, conflict or dispute of any nature that arises in
relation to this Agreement shall be settled exclusively and finally by
arbitration, which will be carried out in conformity with the Rules of
Conciliation and Arbitration of the International Chamber of Commerce (the
"ICC") in effect on the date of this Agreement (the "ICC Rules").  The
arbitration will be carried out by three arbitrators.  In the event that there
are two sides to any such arbitration, one arbitrator shall be appointed by
each side in accordance with Article 4.4 of the ICC Rules as if each side were
a "party" (as such term is used in Article 4.4 of the ICC Rules) and the third
arbitrator shall be selected by the two party-appointed arbitrators or, failing
agreement within 45 days after the notice of intention to arbitrate is filed
with the ICC (or such other period as may be agreed by the two sides to such
arbitration), by the ICC in accordance with the ICC Rules; provided that any
such third arbitrator selected by the ICC shall not be a national of either the
United States or Mexico.  If there are more than two sides to any such
arbitration, then the parties to such arbitration shall appoint the three
arbitrators directly by delivering a written notice of appointment, signed by
all parties to the arbitration, to the ICC within 45 days after the notice of
intention to arbitrate is filed with the ICC (or such other period as may be
agreed by all the parties to such arbitration).  In the event the parties to
the arbitration shall fail so to appoint three mutually acceptable arbitrators,
the arbitrators (or those that have not been appointed) shall be appointed by
the ICC.  Unless all of the parties to such arbitration otherwise agree, all
arbitrators appointed in any such arbitration shall be bilingual in English and
Spanish; provided that in the event that the ICC appoints all three
arbitrators, unless all the parties to such arbitration otherwise agree, one
such arbitrator shall be a national of Mexico, one such arbitrator shall be a
national of





                                       29
<PAGE>   33
the United States and the chairman of such arbitration panel shall be a
national of a country other than the United States or Mexico.

         (b)     The arbitration will be carried out in Mexico D.F., Mexico, in
the English language in conformity with the substantive law set forth in
Section 7.6 and the procedural rules set forth in this Section 7.7 and in
Section 7.8 hereof; provided, however, that any party to the arbitration
proceeding with reasonable prior notice to the other parties to such
arbitration may submit testimony or documentary evidence in Spanish, and shall,
upon request of any other party to the arbitration proceeding, furnish a
translation into English of any such testimony or documentary evidence.  Any
translation of documentary evidence shall be provided a reasonable period of
time before its submission in the proceeding.

         (c)     In order to facilitate the comprehensive resolution of related
disputes between or among any of the parties hereto, and upon request by any
party to the arbitration proceeding, the arbitration panel may at any time
before the first oral hearing of evidence, consolidate the arbitration
proceeding with any other arbitration proceedings between or among all or any
of the parties to this Agreement arising under the Control Trust Agreement.

         (d)     At any oral hearing of evidence, each party to the arbitration
proceeding or its legal counsel shall have the right to examine its witnesses
and to cross-examine the witnesses of an opposing party.  No evidence of any
witness shall be presented in written form unless the opposing party or parties
shall have the opportunity to cross-examine such witness, except as the parties
to the arbitration proceeding otherwise agree in writing or except under
extraordinary circumstances where the interests of justice require a different
procedure.

         (e)     Any decision or award of the arbitrators shall be final and
binding upon the parties to such arbitration, and judgment upon any such
arbitral award may be entered in any court of competent jurisdiction.  The
Parties hereby waive, to the fullest extent permitted by applicable law, any
rights to appeal or to review of such decision or award by any court or
tribunal.

         (f)     To the extent that any Party has or hereafter may acquire any
immunity (sovereign or otherwise) from jurisdiction of any court or from any
legal process (whether through service or notice, attachment prior to judgment,
attachment in aid of execution, execution or otherwise) with respect to itself
or its property, each such Party hereby, to the fullest extent permitted by
applicable law, irrevocably waives such immunity in respect of its obligations
under this Agreement, in connection with any application for judicial
acceptance and an order of enforcement of any such decision or award.





                                       30

         7.8     Remedies.  It is agreed that irreparable damage could occur in
the event that any of the provisions of this Agreement were not performed in
accordance with its specific terms or were otherwise breached and that in
addition to a party's right to seek a temporary restraining order or
preliminary injunction to prevent immediate irreparable harm, an arbitration
panel convened under Section 7.7 shall have the power to grant an injunction or
injunctions to prevent breaches of this Agreement, to the extent that such an
injunction may be granted by a court of competent jurisdiction of the United
States, and the parties shall be entitled to enforce specifically the terms and
provisions of an award of such arbitration panel providing for such an
injunction or injunctions in any such court having jurisdiction, this being in
addition to any other remedy to which they are entitled at law or in equity.
All rights, powers and remedies provided under this Agreement or otherwise
available in respect hereof or at law or in equity shall be cumulative and not
alternative, and the exercise of any thereof by any Party shall not preclude
the simultaneous or later exercise of any other such right, power or remedy by
such Party.

         7.9     Severability.  In the event that any provision of this
Agreement shall be invalid, illegal or unenforceable, the validity, legality
and enforceability of the remaining provisions shall not in any way be affected
or impaired thereby as long as the remaining provisions do not fundamentally
alter the relations among the Parties.

         7.10    Counterparts.  This Agreement may be executed in any number of
counterparts, each of which when so executed and delivered, shall constitute an
original and all together shall constitute one instrument.

         7.11    English Version Governs.  This Agreement, following its
execution and delivery, may be translated into Spanish for the convenience of
the Parties; provided that in the event of any issue of interpretation, the
English version shall always govern and prevail.

         7.12    Further Assurances.  Each Principal Shareholder agrees to
exercise its Beneficiary Rights, if any, and to take such other actions
(including, without limitation, under the Control Trust Agreement) as are
reasonably necessary to implement the provisions of this Agreement.

         7.13    Relationship to Estatutos.  In the event of any conflict or
inconsistency between the provisions of the Estatutos and the provisions of
this Agreement, then as among the parties hereto, the provisions of this
Agreement shall govern.

         7.14    Nextel to Act as Agent and Primary Obligor.

         (a)     Whenever it is provided in this Agreement or the Control Trust
Agreement that any communication is to be made to





                                       31
<PAGE>   35
Nextel, Nextel Investment or any Qualified Affiliate of Nextel Investment, it
shall be sufficient if such communication is made only to Nextel, which shall
act as agent (the "Agent") for Nextel Investment and all Qualified Affiliates
thereof, and, notwithstanding anything to the contrary contained in this
Agreement or the Control Trust Agreement, no such communication need be
delivered to Nextel Investment or any Qualified Affiliate thereof.  Any
instrument signed by the Agent, on behalf of Nextel, Nextel Investment or any
Qualified Affiliate of Nextel Investment, shall be binding on Nextel, Nextel
Investment and such Qualified Affiliate, respectively, and neither any party
hereto nor any other Person shall be required to inquire into the authority of
the Agent in so acting.

         (b)     Nextel shall be and remain obligated under this Agreement and
the Control Trust Agreement as a primary obligor (and not merely as a surety)
in respect of the obligations of Nextel Investment.  Nextel hereby agrees that
for so long as Nextel Investment or any Qualified Affiliate thereof
Beneficially Owns Shares, Nextel shall own all of the shares of Nextel
Investment.

         7.15    Termination of Joint Venture Agreement.  Each of the Company,
Grupo, WVM, and ACC hereby consents to (i) the termination of the Agreement of
Association and Joint Venture in Corporation Mobilcom (the "Joint Venture
Agreement") of April 20, 1993 among Comunicaciones Troncales, S.A. de C.V.,
WVM, ACC, International Wireless Communications ("IWC") and Far East
Agrobusiness Consultants, Limited ("FEAC") as of March 3, 1995 which was the
date upon which each of the other parties thereto consented to termination of
the Joint Venture Agreement and (ii) to the substitution of this Agreement in
its entirety for the Joint Venture Agreement with respect to its relations with
each of the other Parties that is a party to the Joint Venture Agreement.

         7.16    Representations and Warranties.  Each party hereto makes the
representations and warranties set forth in Annex E to the other parties hereto
as of the date it becomes a party to this Agreement and, in the case of the
parties hereto on the Closing Date, as of the Closing Date.

         7.17    Subordinated Amount.  Each of the parties hereto agrees that,
notwithstanding the terms of indebtedness in respect of the Subordinated Amount
(as defined in the Nextel Purchase Agreement), payments shall be made by the
Company in respect of such indebtedness only to the extent that they are
permitted by Section 4.2(b) of the Nextel Purchase Agreement; it being
understood and agreed that the Company shall, upon receipt of the entire $11.4
million capital increase approved by the Company's shareholders meeting
resolution dated June 7, 1996, use the second installment of payments to the
Company from the shareholders participating in the capital increase approved at
such shareholders meeting to repay in its entirety such





                                       32
<PAGE>   36
indebtedness, and such repayment shall be considered to be permitted by Section
4.2(b) of the Nextel Purchase Agreement.

         7.18    Company Covenant Regarding Certain Actions.  The Company
covenants and agrees with the other parties hereto that so long as the Control
Trust Agreement is in effect, it will not take any of the actions referred to
in Section 6.3(d) of the Control Trust Agreement unless such action has been
previously approved by a vote of the Company's shareholders at a duly convened
meeting or unless both (a) Nextel and Grupo, to the extent their consent is
required pursuant to Section 6.3(d) of the Control Trust Agreement, have
expressly consented in writing to the taking of such actions without a
shareholders meeting and (b) each Principal Shareholder Group has received
prior notice of such action.  The Company shall be entitled to assume that the
Control Trust Agreement is in effect unless otherwise notified in writing by
the Control Trustee or a Qualified IPO has occurred.

         7.19    [Intentionally Deleted.]

         7.20    Termination of Rights.  From and after the Transfer by any

                                    - 7 -
<PAGE>   10

any Requirement of Law to effect the transfer to Nextel Investment of such
Selling Shareholder's Equity Interest in accordance with this Section 2(b),
(ii) if Nextel Investment elects to make payment using Nextel Common Stock, the

the Representatives deliver a notice to Nextel Investment that the Selling
Shareholders are willing to receive Nextel Common Stock without there being an
effective registration statement under which to make resales, the date for the
Put Closing shall not be deferred pursuant to this clause (ii) for a period
greater than ten (10) days after the date Nextel Investment receives such
notice), and (iii) if applicable, to the extent necessary to complete the
appraisal procedure described in Section 6 hereof.  The date on which a Put
Closing occurs is referred to herein as a "Put Closing Date".  Each Put Closing
shall be held at such location within New York, New York as shall be designated
in the Put Notice.  At any Put Closing, Nextel Investment shall deliver to each
Selling Shareholder, subject to the continuing accuracy of such Selling

deliver to Nextel Investment a certificate or certificates representing the
Shares constituting such Selling Shareholder's Equity Interest, free and clear
of all Liens (other than arising solely as a result of the existence of the
Shareholders Agreement and the Control Trust Agreement), duly endorsed or

Investment of such Selling Shareholder's Equity Interest.  It is understood and
agreed that (i) with respect to any Shares included in a Selling Shareholder's
Equity Interest which are held in the Control Trust, such Selling Shareholder
shall be deemed to have satisfied its obligations to deliver certificates under
the immediately preceding sentence if it delivers to Nextel Investment the
instructions and certification referred to in clauses (a) and (b) of Section
5.2 of the Control Trust Agreement with respect to such Selling Shareholder's
Beneficiary Rights relating to such Shares, and (ii) failure of any Selling
Shareholder to perform any of its obligations or the inaccuracy of any

action taken by Nextel Investment to exercise any of its rights in respect
thereof, shall not affect the rights of any other Selling Shareholder or the
rights of Nextel Investment under this Agreement, including without limitation
the right of other Selling Shareholders to sell their Shares to Nextel
Investment or the right of Nextel Investment to purchase the Shares of other
Selling Shareholders.  It is similarly understood and agreed that Nextel
Investment's failure to perform any of its obligations





                                     - 8 -

with respect to any Selling Shareholder will not affect its right to purchase
the Shares of any other Selling Shareholder.

                 (c)    Lapse of Put Right.  If, with respect to a particular
occurrence of any particular Put Event, the Selling Shareholders fail to
exercise the Put Right in accordance with Section 2(b) hereof, the Selling
Shareholders' Put Right shall, with respect to such particular occurrence of
such Put Event, automatically lapse and shall be of no further force or effect
with respect to such Put Event.  However, the Selling Shareholders' failure to
exercise the Put Right in accordance with Section 2(b) hereof with respect to a
particular occurrence of a particular Put Event shall not be deemed to be or
construed as a further or continuing waiver of any other occurrence of such Put
Event or any other Put Event, and the Put Right shall continue to be
exercisable in accordance with the terms hereof with respect to any other
occurrence of such Put Event or any other Put Event.

                 (d)    Other Shareholders.  Upon the exercise of the Put
Right, each Other Shareholder shall have the right, and the obligation, to sell
such Other Shareholder's Equity Interest to Nextel Investment at the Put
Closing with respect thereto, at the same Put Price and on the other terms and
conditions provided herein with respect to such exercise, and for such purpose
each Other Shareholder shall be treated as the Selling Shareholders.

3.               Call Rights.

                 (a)    Nextel Investment's Right to Call Shares.  Upon the
terms and subject to the conditions of this Agreement, 1095 days after the
Effective Date, Nextel Investment shall have the right to require Selling
Shareholders to sell to Nextel Investment, and upon exercise by Nextel
Investment of its Call Right in accordance with the terms hereof, the Selling
Shareholders agree to sell to Nextel Investment, all, but not less than all of
the Selling Shareholders' Equity Interest (the "Call Right") at a purchase
price equal to the Call Price.

                 (b)    Exercise of Call Right; Call Closings.  If Nextel
Investment is entitled to exercise its Call Right and desires to do so, Nextel
Investment shall, within 1155 days after the Effective Date, deliver a written
notice (a "Call Notice") to the Representatives specifying a place and date not
earlier than thirty (30) nor later than ninety (90) days from the date such
Call Notice is given for the closing of the purchase by Nextel Investment of
the Selling Shareholders' Equity Interest (a "Call Closing"), provided that
such date shall be deferred to the later of (i) ten (10) days after the date of
obtaining any consents or approvals of any Governmental Authority which are
required by any Requirement of Law to effect the transfer to Nextel Investment
of such Selling Shareholder's Equity Interest in accordance with this Section
3(b), (ii) if Nextel Investment elects to make payment using Nextel Common
Stock, the date a registration





                                     - 9 -
<PAGE>   12
statement is declared effective permitting resales of such Nextel Common Stock
for a thirty (30) day period thereafter (provided that if the Representatives
deliver a notice to Nextel Investment that the Selling Shareholders are willing
to receive Nextel Common Stock without there being an effective registration
statement under which to make resales, the date for the Call Closing shall not
be deferred pursuant to this clause (ii) for a period greater than ten (10)
days after the date Nextel Investment receives such notice) and (iii) if
applicable, to the extent necessary to complete the appraisal procedure
described in Section 6 hereof.  The date on which a Call Closing occurs is
referred to herein as a "Call Closing Date."  Any Call Closing shall be held at
such location within New York, New York as shall be designated in the Call
Notice.  At any Call Closing, Nextel Investment shall deliver to each Selling
Shareholder, subject to the continuing accuracy of such Selling Shareholder's
representations and warranties in Section 8, the applicable Call Price as
contemplated by Section 7 hereof, and each Selling Shareholder shall deliver to
Nextel Investment a certificate or certificates representing the Shares
constituting such Selling Shareholder's Equity Interest, free and clear of all
Liens (other than arising solely as a result of the existence of the
Shareholders Agreement and the Control Trust Agreement), duly endorsed or
accompanied by appropriate stock powers to effect the transfer to Nextel
Investment of such Selling Shareholder's Equity Interest.  It is understood and
agreed that (i) with respect to any Shares included in a Selling Shareholder's
Equity Interest which are held in the Control Trust, such Selling Shareholder
shall be deemed to have satisfied its obligations to deliver certificates under
the immediately preceding sentence if it delivers to Nextel Investment the
instructions and certification referred to in clauses (a) and (b) of Section
5.2 of the Control Trust Agreement with respect to such Selling Shareholder's
Beneficiary Rights relating to such Shares, and (ii) the failure of any Selling
Shareholder to perform its obligations or the inaccuracy of any representations
and warranties in Section 8, and any action taken by Nextel Investment to
exercise any of its rights in respect thereof, shall not affect the rights of
any other Selling Shareholders or the rights of Nextel Investment under this
Agreement, including without limitation the right of other Selling Shareholders
to sell their Shares to Nextel Investment or the right of Nextel Investment to
purchase the Shares of other Selling Shareholders.  It is similarly understood
and agreed that Nextel Investment's failure to perform any of its obligations
with respect to any Selling Shareholder will not affect its right to purchase
the Shares of any other Selling Shareholder.

                 (c)    Other Shareholders.  Upon the exercise of the Call
Right, each Other Shareholder shall have the right, and the obligation, to sell
such Other Shareholder's Equity Interest to Nextel Investment at the Call
Closing with respect thereto, at the same Call Price and on the other terms and
conditions provided herein with respect to such exercise, and for such





                                     - 10 -
<PAGE>   13
purpose each Other Shareholder shall be treated as the Selling Shareholders as
to which Nextel Investment has exercised its Call Right.

4.       Put Events.

                 (a)    Events Constituting Put Events.  A "Put Event" shall be
deemed to have occurred (i) automatically on the date which is 1095 days after
the Effective Date or (ii) if after 365 days after the Effective Date, and
prior to, 1095 days after the Effective Date, any of the events set forth in
clause (1) or (2) below shall have occurred:

                 (1)  The Board or the Company's shareholders shall have taken
action with respect to any of the items listed on Exhibit A hereto and any
Director directly or indirectly designated by one or more of the Selling
Shareholders or all the Shares held by any Selling Shareholder shall not have
voted in favor of such action; or

                 (2)  Solely as a result of the Selling Shareholders' failure
to participate in a capital call approved by the Board in a vote in which any
Director directly or indirectly designated by one or more of the Selling
Shareholders shall not have voted in favor, the Selling Shareholders shall
cease to be entitled to directly or indirectly designate (or shall cease to
have the voting power to elect) at least two Directors on the Board.

5.       Put Price.

                 (a)    Calculation of Put Price.  The Put Price for a Selling
Shareholder's or Other Shareholder's Equity Interest shall be the greater of
the amounts determined in accordance with paragraphs (i) and (ii) below:

                 (i)      The product of (A) the Fair Market Value of a Share
as of the date of the Put Event (the "Put Price Determination Date") and (B)
such Selling Shareholder's Ownership Number as of the Put Closing Date; and

                 (ii)     The product of (A) $150 million and (B) the product
of (1) the Ownership Percentage of such Selling Shareholder as of the date of
this Agreement and (2) a fraction, (x) the numerator of which is the Ownership
Number of such Selling Shareholder as of the Put Closing Date and (y) the
denominator of which is the Ownership Number of such Selling Shareholder as of
the date of this Agreement.

                 (b)    Fair Market Value of a Share.  For purposes of this
Section 5, the "Fair Market Value of a Share" means, as of the applicable
Determination Date:

                 (i)      if thirty percent (30%) or more of the Outstanding
Shares are then held by Persons who are not Affili-





                                     - 11 -
<PAGE>   14
ates or Associates of the Company and if such Shares are of the same or an
equivalent class and series as those that comprise the Selling Shareholders'
Equity Interest (or into which the Selling Shareholders' Equity Interest is
then convertible) and such class(es) or series of Shares is(are) then listed
and traded on a Trading Market, the Current Market Price per share of such
Shares as of such date, provided that if the product of the Fair Market Value
of a Share as of the applicable Determination Date multiplied by the
Outstanding Shares as of such date is a number which exceeds $250 million, then
the "Fair Market Value a Share" (determined as provided in this clause (i))
shall mean such number, reduced by an amount equal to the quotient of (x)
one-half of the amount by which such number exceeds $250 million, divided by
(y) the Outstanding Shares as of such date; or

                 (ii)     if the class(es) and series of Shares which comprise
the Selling Shareholder's or Other Shareholder's, as the case may be, Equity
Interest (or into which the Selling Shareholders' Equity Interest is then
convertible) is (are) not then listed and traded on a Trading Market or if
fewer than thirty percent (30%) of such Shares are then held by Persons who are
not Affiliates or Associates of the Company, the quotient obtained by dividing
the Fair Value of the Company, determined as provided in Section 6, as of the
Put Price Determination Date, by the Outstanding Shares as of the Put Price
Determination Date.

                 (c)    If the Shares, as a result of a dividend or other
distribution, combination, recapitalization, reclassification, exchange,
merger, consolidation or any other change or adjustment in respect of such
capital stock, consist of more than one class or series of capital stock and
each such Share of a different class or series does not have the same value or
is not then convertible into the same class and series, Nextel Investment and
the Representatives shall adjust the foregoing provisions in order to achieve
the same economic result contemplated by this Agreement.

6.       Determination of Fair Value of the Company.

                 The "Fair Value of the Company" as of the applicable
Determination Date shall be (A) the fair value of the Company as of such date
determined by mutual agreement of Nextel Investment and the Representatives or
(B) if no such agreement is reached within ten (10) days after the date a Put
Notice or a Call Notice, as applicable, is delivered (such date of delivery
being referred to as a "Notice Date"), the fair value of the Company as of such
date determined as follows:

                 (a)    Selection of Appraisers.  The Selling Shareholders
collectively through the Representatives, and Nextel Investment, shall each
designate by written notice to the other a firm of recognized national standing
familiar with appraisal techniques applicable to an evaluation of the Company
to serve as an Appraiser pursuant to this Section 6 (the firms designated by
the





                                     - 12 -
<PAGE>   15
Selling Shareholders and Nextel Investment being referred to herein as the
"Selling Shareholders Appraiser" and the "Nextel Appraiser," respectively)
within fifteen (15) days after the applicable Notice Date (or such later date
as to which Nextel Investment and the Representatives agree in writing).  In
the event that either the Selling Shareholders or Nextel Investment fails to
designate its Appraiser within the foregoing fifteen (15)-day time period, the
Appraiser designated shall deliver an Appraiser Certificate as described in
Section 6(b) and the Fair Value of the Company shall be determined on the basis
of such Appraiser Certificate.

                 (b)    Evaluation Procedures.  Each Appraiser shall be
directed to determine the fair value of the Company (which for purposes of such
determination shall be what a willing buyer would pay a willing seller in an
arm's length transaction without application of any minority, liquidity or
other discounts or any control or other premiums) as of the applicable
Determination Date.  Each Appraiser will be directed to deliver an appraiser's
certificate to the Selling Shareholders and Nextel Investment on or before the
forty-fifth (45th) day after the last date by which Nextel Investment and the
Representatives must designate an Appraiser pursuant to Section 6(a) (the
"Certificate Date"), upon the conclusion of its evaluation, which appraiser's
certificate shall set forth such Appraiser's determination of such fair value
of the Company as of such Determination Date (an "Appraiser Certificate").
Each Appraiser will keep confidential all information disclosed by the Company
in the course of conducting its evaluation and, to that end, will execute such
customary documentation as any party or the Company may reasonably request with
respect to such confidentiality obligation.  The Company will provide each
Appraiser with such information concerning the Company as may be reasonably
requested in writing by each Appraiser for purposes of its evaluation
hereunder.  The same information shall be provided to each Appraiser.  The
Appraisers may, but shall be under no obligation to, consult with each other in
the course of conducting their respective evaluations.  Each Appraiser will be
directed to comply with the provisions of this Section 6, and to that end, the
Selling Shareholders and Nextel Investment will provide to their respective
Appraisers a complete and correct copy of this Section 6 (and the definitions
of capitalized terms used in this Section 6 that are defined elsewhere in this
Agreement).

                 (c)    Fair Value Determination.  On the first Business Day
after the Certificate Date, the Fair Value of the Company shall be determined
on the basis of the respective Appraisers' Certificates in accordance with the
provisions of this Section 6(c).  The higher of the values set forth on the
Appraisers' Certificates is hereinafter referred to as the "Higher Value" and
the lower of such values is hereinafter referred to as the "Lower Value".  If
the Higher Value is not more than one hundred ten percent (110%) of the Lower
Value, the Fair Value of the Company will be the arithmetic average of such two
values.  If the Higher





                                     - 13 -
<PAGE>   16
Value is more than one hundred ten percent (110%) of the Lower Value, a third
appraiser shall be selected in accordance with the provisions of Section 6(d)
below, and the Fair Value of the Company will be determined in accordance with
the provisions of Section 6(e) below.

                 (d)    Selection of and Procedure for Third Appraiser.  If the
Higher Value is more than one hundred ten percent (110%) of the Lower Value,
within seven (7) days of the Certificate Date the Selling Shareholders
Appraiser and the Nextel Appraiser shall agree and jointly designate by written
notice to each party a third firm of recognized national standing familiar with
appraisal techniques applicable to an evaluation of the Company, and which has
not been engaged by any of the Selling Shareholders or Nextel Investment or
their respective Affiliates within the immediately preceding 18 months to
perform material services, to serve as an appraiser pursuant to this Section
6(d) (the "Third Appraiser").  If for any reason a Third Appraiser is not so
designated within such seven (7) day period, either Appraiser, or any party
hereto, shall have the right to request that the AAA promptly designate a Third
Appraiser which satisfies the criteria set forth above.  The parties shall
direct the Third Appraiser to determine the fair value of the Company as of the
Determination Date (the "Third Value") in accordance with the provisions of
Section 6(b) above, and to deliver to the parties an Appraiser's Certificate on
or before the 30th day after the designation of such Third Appraiser.  The
Third Appraiser will be directed to comply with the provisions of this Section
6(d), and to that end the parties will provide to the Third Appraiser a
complete and correct copy of this Section 6(d) (and the definitions of
capitalized terms used in this Section 6(d) that are defined elsewhere in this
Agreement).

                 (e)    Alternative Determination of Fair Value.  On the first
Business Day after the date of delivery of the Appraiser's Certificate of the
Third Appraiser, the Fair Value of the Company will be determined as provided
in this Section 6(e).  The Fair Value of the Company will be (w) the Lower
Value, if the Third Value is less than the Lower Value, (x) the Higher Value,
if the Third Value is greater than the Higher Value, (y) the arithmetic average
of the Third Value and the other Value (Lower or Higher) that is closer to the
Third Value if the Third Value falls within the range between (and including)
the Lower Value and the Higher Value and (z) the Third Value, if the Lower
Value and the Higher Value are equally close to the Third Value.

                 (f)    Fair Value if Appraiser Valuation Exceeds $250 Million.
Notwithstanding the foregoing provisions of this Section 6, if the Fair Value
of the Company determined in accordance with such provisions is a number which
exceeds $250 million, then the Fair Value of the Company will be such number,
reduced by one-half of the amount by which such number exceeds $250 million.





                                     - 14 -
<PAGE>   17
                 (g)    Costs.  The Selling Shareholders and Nextel Investment,
respectively, will bear the cost of the respective Appraisers designated.  If
the Higher Value is not more than one hundred fifteen percent (115%) of the
Lower Value, or if the Higher Value and the Lower Value are equally close to
the Third Value, the Selling Shareholders collectively, and Nextel Investment,
shall each bear fifty percent (50%) of the cost of the Third Appraiser, if any;
otherwise, the party (which for this purpose shall mean the Selling
Shareholders collectively or Nextel Investment) whose Appraiser's determination
of the fair value of the Company is further away from the Third Value shall
bear the entire cost of the Third Appraiser.  The parties agree to pay when due
the fees and expenses of the Appraisers in accordance with the foregoing
provisions.

                 (h)    Conclusive Determination.  To the fullest extent
permitted by law, the determination of the Fair Value of the Company made
pursuant to this Section 6 shall be final and binding on the parties hereto,
and such determination shall not be appealable to any court; provided that the
foregoing shall not limit a party's rights to seek judicial enforcement of the
obligations of the other parties hereunder, including enforcement of a party's
right to receive the Put Price or Call Price as determined pursuant to this
Agreement.

7.       Payment of Put Price and Call Price.

                 (a)    Form of Payment.  Subject to the further provisions of
this Section 7, Nextel Investment shall pay the Put Price or Call Price to each
Selling Shareholder or Other Shareholder at any Put Closing or Call Closing in
any combination that Nextel Investment may elect (such combination to be the
same combination with respect to each such Selling Shareholder, but which
combination may differ with respect to each such Other Shareholder) of (i) cash
in United States dollars delivered, with respect to amounts of or in excess of
one million dollars ($1,000,000), by wire transfer of immediately available
funds to the account or accounts designated at least five (5) Business Days
prior to such Put Closing or Call Closing by such Selling Shareholder to Nextel
Investment, or with respect to amounts of less than one million dollars
($1,000,000) by bank check and (ii) a certificate or certificates representing
duly authorized, validly issued, fully paid and nonassessable shares of Nextel
Common Stock, which upon delivery at the Put Closing or the Call Closing, as
applicable, shall be free and clear of any Liens and (unless the
Representatives have delivered a notice to Nextel Investment that the Selling
Shareholders are willing to receive Nextel Common Stock without there being an
effective registration statement under which to make resales) shall be freely
transferable for a thirty (30) day period after the Put Closing or the Call
Closing (subject to the terms of Section 7(d)) by such Selling Shareholder or
Other Shareholder pursuant to an effective registration statement under the
Securities Act covering the resale by such Selling Shareholder or Other
Shareholder of such





                                     - 15 -
<PAGE>   18
shares and which shares shall have been approved for listing and trading on a
United States national securities exchange or the NNM (the "Nextel Stock
Consideration"), having a total value equal to the applicable Put Price.
Notwithstanding the foregoing, if Nextel Investment does not make payment in
whole in cash at the Put Closing or Call Closing, Nextel Investment will be
deemed to have elected (as of the date of the Put Notice or Call Notice, as
applicable) to pay the Put Price or Call Price in Nextel Common Stock to the
extent payment is not made in cash.  Each of the Selling Shareholders and Other
Shareholder will pay all stamp and other similar taxes, if any, which may be
payable in respect of the sale and delivery by such Selling Shareholder or
Other Shareholder to Nextel Investment of any of its Shares and will save
Nextel Investment harmless against any loss or liability resulting from
nonpayment or delay in payment of any such tax.  All payments to be made by
Nextel Investment may be reduced by any taxes or other fees that Nextel
Investment is required to withhold, under any applicable Requirement of Law.

                 (b)    Valuation of Nextel Common Stock.  For purposes of this
Section 7, the value of the Nextel Stock Consideration shall be the product of
the Current Market Price per share of the shares of Nextel Common Stock
comprising the Nextel Stock Consideration as of the Put Closing Date or the
Call Closing Date, as applicable, times the number of such shares.

                 (c)    Definition of "Nextel Common Stock".  For purposes of
this Agreement, "Nextel Common Stock" means and includes (i) the class of stock
designated on the date hereof as the Class A common stock, par value $0.001 per
share, of Nextel and (ii) any other class of stock of Nextel or equity
securities of another corporation or other business entity resulting from any
changes of or to such common stock as a result of any dividend or other
distribution, split-up, combination, recapitalization, reclassification,
exchange, merger, consolidation or any other change or adjustment in respect of
such common stock.

                 (d)    Registration Mechanics.  If Nextel Investment elects
(or is deemed to have elected) to make payment of the Put Price or Call Price
using Nextel Common Stock, Nextel shall as soon as practicable after delivery
of the Put Notice or Call Notice use all reasonable efforts to cause a
registration statement to be filed and declared effective permitting the
Selling Shareholders and the Other Shareholders to transfer for a thirty (30)
day period after the Put Closing or Call Closing, as the case may be, the
Nextel Stock Consideration to be received by such Selling Shareholder or Other
Shareholder hereunder, provided that, Nextel may postpone filing a registration
statement at any time when:  (i) financial statements meeting the requirements
of the Commission cannot with reasonable efforts be obtained; (ii) Nextel is in
possession of material non-public information, the disclosure of which at that
time Nextel's Board of Directors determines in good faith would not be in the
best interests of Nextel or (iii) such registration would adversely affect in a





                                     - 16 -
<PAGE>   19
significant manner (including, without limitation, through the premature
disclosure thereof) a proposed financing, reorganization, recapitalization,
merger, consolidation or similar transaction involving Nextel or its
Affiliates; provided, however, that Nextel may postpone filing a registration
statement pursuant to clauses (i), (ii) or (iii) for such reasons only for up
to one hundred twenty (120) days from the date of receipt of the Put Notice or
Call Notice.  If during the 30-day period after the Put Closing or Call Closing
there occurs any development or event which requires the making of any change
in such registration statement or the related prospectus (in each case as
amended or supplemented) so that they will not contain any untrue statement of
a material fact or omit to state a material fact required to be stated therein
or necessary to make the statements contained therein, in light of the
circumstances under which they were made, not misleading:  (i) Nextel shall
immediately notify each Selling Shareholder or Other Shareholder; (ii) upon
receipt of such notice, such persons shall discontinue dispositions of the
Nextel Stock Consideration until such persons shall have received copies of the
amended or supplemented prospectus contemplated above or have been advised by
Nextel in writing that use of the prospectus may be resumed; (iii) as promptly
as practicable, but not later than one hundred twenty (120) days after such
notice, Nextel shall take such action as is necessary to amend or supplement
the registration statement to permit sales of the Nextel Stock Consideration to
be made thereunder and shall furnish such amended or supplemented prospectus in
reasonable quantities (as thereafter deliverable to the purchasers of shares of
Nextel Common Stock comprising the Nextel Stock Consideration) to each such
Selling Shareholder or Other Shareholder so that such prospectus will not
contain any untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements
contained therein, in light of the circumstances under which they were made,
not misleading; and (iv) the 30-day period shall be extended by the number of
days during which the Selling Shareholder and Other Shareholders are required
to discontinue dispositions of the Nextel Stock Consideration.  Each Selling
Shareholder or Other Shareholder agrees that in undertaking the registration of
Nextel Common Stock contemplated hereby Nextel shall comply with the applicable
requirements of the agreements relating to the registration of Nextel Common
Stock listed on Exhibit B hereto, as in effect on the date hereof, as well as
other registration rights agreements entered into the future, provided such
future agreements do not prohibit, or restrict in a manner which deprives the
Selling Shareholders or the Other Shareholders of the overall material benefits
of their rights with respect to, the registration of Nextel Common Stock under
this Agreement, (such agreements on Exhibit B and future agreements being
herein referred to as the "Registration Rights Agreements"), including without
limitation, rights of parties to the Registration Rights Agreements to include
Shares under the registration statement contemplated by this Agreement; it
being further agreed that, subject to the immediately preceding





                                     - 17 -
<PAGE>   20
proviso, the Registration Rights Agreements, shall, to the extent any
inconsistency exists between this Agreement and the Registration Rights
Agreements, govern the registration process.  Nextel represents and warrants to
each of the Selling Shareholders that as of the date hereof the Registration
Rights Agreements listed on Exhibit B hereto are the only agreements to which
Nextel is a party or by which it is bound relating to the registration of
Nextel Common Stock.  Each Selling Shareholder or Other Shareholder shall be
solely responsible for and shall pay or cause to be paid, as appropriate, all
underwriting discounts and commissions and brokerage fees attributable to the
sale of such Selling Shareholder's Nextel Common Stock and the fees and
disbursements of any counsel or other advisors or experts retained by such
Selling Shareholder, it being understood and agreed that Nextel shall be solely
responsible for and shall pay or cause to be paid all other expenses and fees
incurred by Nextel in connection with the registration of Nextel Common Stock
pursuant to this Section 7(d).

                 (e)    Securities Law Restrictions.

                 (i) Unless it sells Nextel Common Stock to be acquired under
this Agreement, pursuant to an effective registration statement that is
declared effective at the Put Closing or Call Closing, each Selling Shareholder
and Other Shareholder agrees that it shall not sell, transfer, assign, pledge
or otherwise dispose of Nextel Common Stock unless such sale, transfer,
assignment, pledge or other disposition has been registered (with respect to
which Nextel has no obligation to undertake any such registration except as
expressly provided in Section 7) or is exempt under the Securities Act and has
been registered or  qualified or is exempt from registration or qualification
under applicable state securities laws and each such Selling Shareholder and
Other Shareholder provides to Nextel an opinion of counsel reasonably
satisfactory to Nextel that a sale, transfer, assignment, pledge or other
disposition of such Nextel Common Stock may be made without registration.

                 (ii)     Each Selling Shareholder and Other Shareholder
acknowledges that until such time as the Nextel Common Stock to be acquired by
such Selling Shareholder or Other Shareholder hereunder has been sold in a
public offering pursuant to an effective registration statement under the
Securities Act, or Rules 144 or 145 thereunder (or any successor rules), each
certificate representing such Nextel Common Stock shall be endorsed with the
following legend:

                 THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
                 REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
                 UNDER ANY STATE SECURITIES LAWS, AND MAY NOT BE SOLD,
                 ASSIGNED, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF UNLESS
                 THEY HAVE FIRST BEEN REGISTERED UNDER SUCH ACT AND APPLICABLE
                 STATE SECURITIES LAWS OR UNLESS AN

                 EXEMPTION FROM SUCH REGISTRATION IS AVAILABLE AND NEXTEL
                 COMMUNICATIONS, INC. SHALL HAVE RECEIVED, AT THE EXPENSE OF
                 THE HOLDER HEREOF, EVIDENCE OF SUCH EXEMPTION REASONABLY
                 SATISFACTORY TO THE CORPORATION (WHICH MAY INCLUDE, AMONG
                 OTHER THINGS, AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO
                 NEXTEL COMMUNICATIONS, INC.).

                 (iii)  Each Selling Shareholder and Other Shareholder
acknowledges that Nextel may place stop transfer orders against the
registration or transfer of any Nextel Common Stock until such time as the
requirements of the foregoing legend are satisfied.

                 (iv)  At the request of a Selling Shareholder or Other
Shareholder, Nextel will promptly cause the foregoing legend to be removed and
any stop transfer orders rescinded with respect to any shares of Nextel Common
Stock acquired by such Selling Shareholder or Other Shareholder hereunder, upon
presentation to Nextel of evidence reasonably satisfactory to it (which may
include, among other things, an opinion of counsel reasonably satisfactory to
it) that such legend is no longer applicable to such shares.

8.       Representations and Warranties.

                 (a)     Selling Shareholders.  Each Selling Shareholder and
Other Shareholder hereby represents and warrants (severally and not jointly,
solely with respect to such Selling Shareholder or Other Shareholder) to Nextel
Investment as follows as of the date hereof and as of the Put Closing or Call
Closing (and Nextel Investment's obligation to acquire such Selling
Shareholder's or Other Shareholder's Shares at the Put Closing or Call Closing
shall be subject to such representations and warranties being true and accurate
as of such date):

                 (i)      Corporate Organization.  Such Selling Shareholder or
any Other Shareholder that is a corporation is a corporation (or, in the case
of Carlyle, limited liability company and in the case of Other Shareholders
that are partnerships or limited partnerships, partnership or limited
partnership) duly organized and validly existing under the laws of its
jurisdiction of organization.

                 (ii)     Corporate Power and Authority.  Such Selling
Shareholder or any Other Shareholder that is a corporation has the requisite
corporate (or, in the case of Carlyle, limited liability company and in the
case of Other Shareholders that are partnerships or limited partnerships,
partnership or limited partnership) power and authority to enter into this
Agreement, to perform its obligations hereunder and to consummate the
transactions contemplated hereby.  The execution, delivery and performance by
such Selling Shareholder or any Other Shareholder that is not a natural person
of this Agreement and the consummation by





                                     - 19 -
<PAGE>   22
such Selling Shareholder or Other Shareholder of the transactions contemplated
hereby have been duly authorized by all requisite corporate (or, in the case of
Carlyle, limited liability company and in the case of Other Shareholders that
are partnerships or limited partnerships, partnership or limited partnership)
action on the part of such Selling Shareholder or Other Shareholder, and no
other corporate (or, in the case of Carlyle, limited liability company and in
the case of Other Shareholders that are partnerships or limited partnerships,
partnership or limited partnership) proceedings on the part of such Selling
Shareholder or Other Shareholder or its stockholders (or, in the case of
Carlyle, members and in the case of Other Shareholders that are partnerships or
limited partnerships, partners) are necessary to authorize this Agreement and
transactions contemplated hereby.  This Agreement has been duly executed and
delivered by, and constitutes the valid and binding obligation of, such Selling
Shareholder or Other Shareholder, enforceable against such Selling Shareholder
or Other Shareholder in accordance with its terms.

                 (iii)    Shares Free of Liens.  As of the Put Closing or Call
Closing, as the case may be, the transfer of such Selling Shareholder's or
Other Shareholder's Shares pursuant to this  Agreement (A) (1) does not and
will not result in the creation or imposition of any Lien (other than any Lien
solely created by action of Nextel Investment or any of its Affiliates) upon
any of such Selling Shareholder's or Other Shareholder's Shares, (2) does not
and will not violate any Requirement of Law applicable to it and (3) does not
and will not conflict with or result in any breach of any term, condition or
provision of, or constitute (with due notice or lapse of time or both) a
default under, or pursuant to the terms of, any mortgage, deed of trust or
other agreement or instrument to which it is a party or by which it or any of
its properties is bound, other than the Control Trust Agreement and
Shareholders Agreement, and (B) if applicable, does not and will not conflict
with its charter documents.  As of the Put Closing or Call Closing, as the case
may be, each of such Selling Shareholder's or Other Shareholder's Shares to be
sold to Nextel Investment hereunder will be (i) duly authorized, validly
issued, fully paid and non-assessable Shares, (ii) delivered free and clear of
all Liens (other than any Lien solely created by action of Nextel Investment or
any of its Affiliates), and not be subject to any voting or trust agreement,
proxy, buy-sell agreement, right of first refusal, preemptive-right or similar
restriction, except in the case of a Selling Shareholder, as expressly
contemplated by the Control Trust Agreement and the Shareholders Agreement.

                 (iv)     No Conflict.  The execution, delivery and performance
by it of this Agreement, and the consummation by it of the transactions
contemplated hereby (A)(1) does not and will not violate any Requirement of Law
applicable to it and (2) does not and will not conflict with or result in any
breach of any term, condition or provision of, or constitute (with due notice





                                     - 20 -
<PAGE>   23
or lapse of time or both) a default under, or pursuant to the terms of, any
mortgage, deed of trust or other agreement or instrument to which it is a party
or by which it or its properties is bound, other than the Control Trust
Agreement and Shareholders Agreement and (B) does not and will not conflict
with its organizational documents.

                 (v)      Consents/Approvals.  As of the Put Closing or Call
Closing, as the case may be, (A) no consents of, filings with, authorizations
or other actions of, any Governmental Authority will be required to be
received, made or filed by, or taken on behalf of, such Selling Shareholder's
or Other Shareholder's transfer of the Shares pursuant to this Agreement, other
than those that have or will have been received, made, filed or taken, and (B)
no consent, approval, waiver or other action by any Person under any contract,
agreement, indenture, lease or other similar document to which such Selling
Shareholder or Other Shareholder or any of its properties is bound is required
for the transfer of the Shares pursuant to the Agreement, except for any such
consents, approvals, waivers or other actions (x) required under the Control
Trust Agreement or Shareholders Agreement, if any, and (y) that have been or
will have been previously obtained or completed.

                 (vi)     Share Ownership.  As of the date hereof, such Selling
Shareholder or Other Shareholder Beneficially Owns the Shares set forth next to
its name on Schedule II hereto.  As of the date hereof, such Selling
Shareholder or Other Shareholder has entered into no agreements or arrangements
to dispose of or grant any interest in such Shares or to otherwise acquire any
Shares or any interest in any Shares, except for this Agreement and, with
respect to each Selling Shareholder, the Stockholders Agreement and the Control
Trust Agreement.

                 (vii)    Compliance With Securities Act.  Any right or Nextel
Common Stock to be acquired by such Selling Shareholder or Other Shareholder
pursuant to this Agreement will be acquired for such Selling Shareholder's or
Other Shareholder's own account and not with a view to, or present intention
of, distribution thereof in violation of the Securities Act, or any applicable
state securities laws and will not be disposed of in contravention of the
Securities Act or any applicable state securities laws.  Each Selling
Shareholder or Other Shareholder is an "Accredited Investor" as such term is
defined in Rule 501 promulgated under the Securities Act.  Each Selling
Shareholder or Other Shareholder understands that as a result of executing this
Agreement, it may be forced to sell its Shares in exchange for Nextel Common
Stock under this Agreement, based on decisions made by the Representatives and
Nextel Investment and is knowledgeable about Nextel and its operations, is
capable of evaluating the risks and merits of entering into this Agreement and
its possible investment in Nextel Common Stock and has had an opportunity to
ask questions and receive answers concerning Nextel and the Nextel Common
Stock.  Each Selling Shareholder or Other





                                     - 21 -
<PAGE>   24
Shareholder is able to bear the economic risk of any investment in the Nextel
Common Stock for an indefinite period of time.

                 (b)    Nextel and Nextel Investment.  Each of Nextel and
Nextel Investment hereby represents and warrants to each of the Selling
Shareholders as follows as of the date hereof and as of the Put Closing or Call
Closing:

                 (i)      Corporate Organization.  They are corporations duly

of them, and no other corporate proceedings on the part of either of them or
their respective stockholders are necessary to authorize this Agreement and the
transactions contemplated hereby.  This Agreement has been duly executed and
delivered by each of them and constitutes the valid and binding obligation of
each of them, enforceable against each of them in accordance with its terms.

                 (iii)    No Conflict.  The execution, delivery and performance
by them of this Agreement, and the consummation by them of the transactions
contemplated hereby (A)(1) does not and will not violate any Requirement of Law

9.       Termination.

         This Agreement shall terminate and be of no further force or effect
upon the consummation of an IPO in one or more of a series of public offerings
in which Shares are sold to parties other than Nextel and its Affiliates at a
price to the public resulting in gross proceeds to the Company in the aggregate
of not less than $100 million and as a result of which the class(es) and series
or equivalent class(es) and series of Shares owned by the Selling Shareholders
(including without limitation classes and series into which such Shares are
then convertible) are listed and traded on any Trading Market.  This Agreement
shall also terminate if the Effective Date has not occurred on or before 1095
days after the date of this Agreement.

10.      Miscellaneous.

                 (a)    Further Assurances.  Subject to the terms and
conditions herein provided, each of the parties hereto agrees to use all
reasonable efforts to take, or cause to be taken, all actions and to do, or
cause to be done, all things necessary, proper or advisable under applicable
laws and regulations to perform its obligations hereunder and to consummate and
make effective the transactions contemplated to be consummated by such party
under this Agreement.  Without limitation of the generality of the foregoing,
each party hereto agrees to cooperate with the other parties in obtaining as
promptly as practicable after the exercise of a Put Right or Call Right,
respectively, any and all consents or approvals of any Governmental Authority
referred to in Sections 2(b) or 3(b), respectively, with respect to such
exercise and the related Put Closing or Call Closing, respectively.

                 (b)    Binding Effect; Obligations Several and Not Joint.
This Agreement shall be binding upon and inure to the benefit of the respective
successors, heirs, personal representatives and permitted assigns of the
parties hereto, provided that neither this Agreement nor any rights or
obligations hereunder may be assigned or delegated by Nextel Investment, the
Selling Shareholders or the Other Shareholders without the prior written
consent of Nextel Investment and the Representatives except that (i) Nextel
Investment may assign in whole or in part its rights and obligations to any
Affiliate of Nextel, provided that Nextel Investment continues to be bound by
its obligations hereunder (ii) Nextel Investment may assign its rights and
obligations to any Affiliate of Nextel into which Nextel Investment is merged,
consolidated or otherwise combined and (iii) subject to the terms of the
immediately following sentence, any Selling Shareholder  may assign in whole
its rights and obligations hereunder to any Person in connection with a
transfer of Shares held by such Selling Shareholder to such Person, provided
such Person agrees with Nextel Investment in writing reasonably acceptable to
Nextel Investment to be bound by all of the terms of this Agreement applicable
to such Selling Shareholder and provided such transfer





                                     - 23 -
<PAGE>   26
or disposition complies with the requirements of the Control Trust Agreement,
Shareholders Agreement and Estatutos and all applicable laws, including without
limitation the Securities Act.  Notwithstanding the foregoing, (i) each of the
Selling Shareholders and Other Shareholders shall not transfer or otherwise
dispose of any interest in the Shares without obtaining a written commitment,
reasonably acceptable to Nextel Investment, from the acquiror of such interest
in the Shares that it and any other future subsequent acquirors of any interest
in such Shares shall be obligated to sell any Shares upon the exercise of the
Call Right by Nextel Investment in accordance with the terms of this Agreement
applicable to the Selling Shareholders or Other Shareholders, as the case may
be, and prior to any such transfer or disposition, a legend will be placed on
the Shares in both English and Spanish indicating that the Shares are subject
to the obligations of the Call Right under this Agreement; and (ii) the rights
of any Selling Shareholder under this Agreement shall be assignable only in
connection with a transfer of all of such Selling Shareholder's Shares to a
single Person who or which agrees with Nextel Investment in writing reasonably
acceptable to Nextel Investment to be bound by all of the terms of this
Agreement applicable to such Selling Shareholder.  The obligations of the
parties hereunder shall be several and not joint, and the failure of any party
to perform its obligations hereunder shall not limit or impair the obligations
of any other party or the right of any other party to enforce such obligations.
In the event of any inconsistency or conflict between the provisions of this
Agreement and the provisions of the Shareholders Agreement or the Control Trust
Agreement which would (x) prevent, impair or delay the Selling Shareholders'
exercise of the Put Right and receipt of the Put Price (y) prevent, impair or
delay Nextel Investment's exercise of the Call Right (and upon such exercise,
the Selling Shareholders receipt of the Call Price) or (z) limit Nextel
Investment's ability to purchase Shares under this Agreement without having to
purchase Shares of other persons or waive any rights under the provisions of
the Shareholders Agreement or the Control Trust Agreement, such provisions in
the Shareholders Agreement or the Control Trust Agreement shall be deemed to be
superseded by this Agreement to the extent necessary to eliminate such
inconsistency or conflict.

                 (c)    Entire Agreement.  This Agreement and the other
agreements and instruments entered into in connection herewith constitute the
entire agreement of the parties hereto with respect to the subject matter
hereof and thereof (other than certain representations with respect to matters
related to compliance with the Securities Act obtained from the Other
Shareholders) and shall supersede any prior expressions of intent or
understanding with respect to the transactions provided for herein and therein,
provided that, except as set forth in this Section 10(c), this Section 10(c) is
not intended to and shall not alter or affect in any manner the rights and
obligations of





                                     - 24 -
<PAGE>   27
the parties pursuant to the Transaction Agreements, as the same have been or
may be amended.

                 (d)    Costs and Expenses.  Except as otherwise set forth
herein, each party agrees to bear its own expenses, fees and costs incurred in
connection with the transactions contemplated by this Agreement.

                 (e)    Brokerage.  There are no valid claims for brokerage
commissions, finder's fees or similar compensation in connection with the
transactions contemplated by this Agreement based on any arrangement or
agreement made by or on behalf of any party hereto and each party will
indemnify and hold the other party harmless against any liability or expense to
it arising out of such a claim.

                 (f)    Amendment.  Any amendment hereto shall be effective
only if in writing and signed by each of Nextel Investment and the
Representatives.

                 (g)    Waiver; Cumulative Rights.  No provision of this
Agreement shall be deemed to have been waived by any act or knowledge of any
party or of such party's agents, officers or employees, but only by an
instrument in writing specifying such waiver signed by Nextel Investment and
delivered to the Representatives, if Nextel or Nextel Investment is the waiving
party, or in writing signed by such party or the Representatives and delivered
to Nextel Investment, if any of the Selling Shareholders or Other Shareholders
is the waiving party.  The failure or delay of any party to require performance
by another party of any provision hereof shall not affect its right to require
performance of such provision unless and until such performance has been waived
in writing.  Each and every right hereunder is cumulative and may be exercised
in whole or in part from time to time.

                 (h)    Notices.  All notices, demands, requests, certificates
or other communications under this Agreement shall be in writing and shall be
mailed by certified or registered mail (return receipt requested) with charges
prepaid, hand delivered or sent by facsimile transmission or by commercial
courier to the address set forth below for each of the parties (or at such
other address as shall be specified by a party by like notice to all of the

interpreted in accordance with the internal laws of the State of New York,
without reference to its conflicts of law principles.

                 (j)    Counterparts.  This Agreement may be signed in two or

of this Agreement.

                 (l)    Representatives.  Each of the Selling Shareholders and

"a party", "each of the parties", "any party", "all parties" or similar
reference), and except for the representations of Nextel set forth in Section
8(b), the provisions of this Agreement shall create no obligations on the part

         convertible but the Shares into which such options, warrants and other
         securities are exercisable or convertible shall not be included and,

hereby acknowledged by the parties, the parties agree as follows:

                 1.       Definitions.  Capitalized terms not defined herein
shall have the meanings given to such terms in the Put-Call Agreement.

                 2.       Effective Date.  The parties hereby acknowledge that
the Effective Date shall occur upon a closing under each of the Share Purchase
and Call Option Agreement, dated as of the date hereof, among certain
shareholders of Grupo and Nextel Investment and the Subscription Agreement,
dated as of the date hereof, among the Company and Nextel Investment.

                 3.       Amendment to "Current Market Price" Definition.  The
definition of "Current Market Price" in the Put-Call Agreement is hereby
amended and restated as follows:

                 "Current Market Price" per share of common stock of an issuer
                 as of the applicable Determination Date shall be deemed to be
                 the average of the daily closing price per share of such
                 common stock for the 30 consecutive Trading Days immediately
                 prior to such date; provided, however, that in the event that
                 during such 30-Trading Day period (and for purposes of Section
                 7(b), in the event that during such 30-Trading Day period and
                 after such 30-Trading Day period and prior to the Put Closing
                 or the Call Closing, as the case may be) there occurs a record
                 date or effective date in respect of any changes of or to such
                 common stock as a result of any dividend or other distribution,
                 split-up, combination, recapitalization, reclassification,
                 exchange, merger, consolidation or any other change or
                 adjustment in respect of such common stock (including without
                 limitation an extraordinary cash dividend) then the "Current
                 Market Price" shall be adjusted appropriately.  The closing
                 price for each such Trading Day shall be the last sale price,
                 regular way, or, in case no such sale takes place on such day,
                 the average of the

                 closing bid and asked prices, regular way, on the Trading
                 Market, as reported in the principal consolidated transaction
                 reporting system or by the NNM with respect to securities
                 listed or admitted to trading on such Trading Market,
                 respectively.

                 4.       Put Events.  Section 4(a) of the Put-Call Agreement
is hereby amended and restated in its entirety to read as follows: 

                          "(a)  Events Constituting Put Events.  A "Put Event"
                 shall be deemed to have occurred (i) automatically on the date
                 which is 1095 days after the Effective Date or (ii) if after
                 365 days after the Effective Date, and prior to 1095 days after
                 the Effective Date, any of the events set forth in clauses (1),
                 (2), (3) or (4) below shall have occurred:
                    
                 (1)      The Company has taken action with respect to any of
                          the items listed on Exhibit A hereto and any Director
                          directly or indirectly designated by one or more of
                          the Selling Shareholders shall have voted against
                          such action or any Selling Shareholder shall have
                          voted all the Shares held by such Selling Shareholder
                          against such action; provided that if the Company
                          takes any of the actions listed on Exhibit A without
                          a vote of the Board or the Company's shareholders,
                          such action shall constitute a "Put Event" unless the
                          Company prior to taking such action has provided
                          written notice to the Selling Shareholders of its
                          intention to take such action, in which case a "Put
                          Event" shall only be deemed to occur, if within
                          fifteen days after provision of such written notice,
                          Associated and WVM indicate in writing their
                          disagreement with such proposed action; or

                 (2)      The Selling Shareholders shall cease to be entitled
                          to directly or indirectly designate (or shall cease
                          to have the voting power to elect) at least two
                          Directors on the Board for any reason other than as a
                          result of the sale or other transfer of the Shares
                          Beneficially Owned by one or more of the Selling
                          Shareholders; provided that to the extent the event
                          resulting in the Selling Shareholders ceasing to be
                          entitled to directly or indirectly designate (or
                          ceasing to have the voting power to elect) at least
                          two Directors, resulted in a "Put Event" occurring
                          under clause (1) of Section 4(a), no "Put Event"
                          shall deem to occur under this clause (2);

                 (3)      Section 5.10 of the Shareholders Agreement shall have
                          been breached; or

                 (4)      Neither the Board nor the Company's shareholders
                          shall have voted on the adoption of, or approval of
                          any material deviation from, a business plan,
                          marketing plan, capital expenditure plan or operating
                          budget of the Company or of its direct or indirect,

                          days after the date which is 365 days after the
                          Effective Date, unless during such 90 day period one
                          of the events listed in clauses (1), (2) or (3) of
                          this Section 4(a) has occurred."

the Put-Call Agreement shall be amended and restated in its entirety to read as
follows:

any time after January 1, 1999, requesting a Liquidity Event, referencing this
Agreement and designating a number of Shares Beneficially Owned (as defined in
the Shareholders Agreement) by Grupo and its Qualified Affiliates to be
included in such Liquidity Event (which number may not exceed the Post-Transfer
Number), Nextel Investment shall cause a Liquidity Event in respect of such
number of Shares specified in the Liquidity Request to close within one year
after the delivery of the Liquidity Request; provided, that Grupo shall (i)
have used its, and caused its Qualified Affiliates to have used their,
reasonable best efforts to further the occurrence of the Liquidity Event,
including, without limitation, by negotiating in good faith with third parties
with respect to the terms and Fair Cash Value for such Liquidity Event and (ii)
not be in breach under the Control Trust Agreement, if in effect, and the
Shareholders Agreement (other than such breaches which would not be considered
material).  In the case of a Liquidity Event other than one in which Grupo has
negotiated the terms thereof with a third party, Nextel Investment shall
provide Grupo with reasonable advance notice (the "Closing Notice") of the
closing and the other material details of the Liquidity Event.

                 (b)  If such Liquidity Event is other than an Offering and
Qualified Securities constitute all or part of the consideration used in such
Liquidity Event, then Nextel Investment or any purchaser of the Shares
designated by Nextel Investment shall reimburse Grupo for one-half of any
Resale Costs; provided, that such reimbursement amount shall not exceed one
percent of the proceeds from the resale of Qualified Securities during the

in connection with such Offering shall be borne in accordance with the
provisions of the Registration Rights Agreement and Grupo shall otherwise take
such actions as are customary for secondary sellers in a registered public
offering and are reasonably requested by the Underwriter.





                                       7
<PAGE>   8
                 (d)  It is understood and agreed that (i) Nextel Investment
shall be obligated to cause only one Liquidity Event hereunder and (ii) in the
event that Nextel Investment fails to cause a Liquidity Event to close within
one year after the delivery of the Liquidity Request, Grupo shall have a right
to demand registration under Section A.5 of the Registration Rights Agreement.

                 Section 3.  Fair Cash Value.  Fair Cash Value for the number
of Shares specified in the Liquidity Request shall be the U.S. dollar cash
amount equal to (i) an amount determined by mutual agreement of Grupo and
Nextel Investment or a buyer designated by Nextel Investment; and (ii) if such
an agreement under clause (i) cannot be reached within 60 days after the date
of delivery of the Liquidity Request (such date of delivery being, the
"Liquidity Request Date"), an amount determined upon the request of either
Nextel Investment or Grupo (the date of the first such request being, the
"Appraisal Request Date") as follows:

                 (a)  Selection of Appraisers.  Grupo shall designate by
written notice to Nextel the Grupo Appraiser and Nextel Investment shall
designate by written notice to Grupo the Nextel Appraiser.  In the event that
only one Appraiser is designated within 15 days after the Appraisal Request
Date (either as the result of both Party's designating the same Appraiser or
one Party failing to designate an Appraiser within such 15-day period), the
Appraiser designated shall deliver an Appraiser Certificate as described in
Section 3(b), the Fair Cash Value shall be determined on the basis of such
Appraiser Certificate and the Parties shall each pay one-half of such
Appraiser's fees and expenses.  If the Grupo Appraiser and the Nextel Appraiser
are not the same, then Grupo shall pay all of the Grupo Appraiser's fees and
expenses and Nextel Investment shall pay all of the Nextel Appraiser's fees and
expenses.

                 (b)   Evaluation Procedures.  Each Appraiser shall be directed
to determine the value (which for purposes of such determination shall be what
a willing buyer would have paid a willing seller on the Liquidity Request Date
in an arm's length transaction) of all outstanding Shares and then designate
the Fair Cash Value by multiplying such valuation by the percentage of the
outstanding Shares represented by the number of Shares specified in the
Liquidity Request.  Each Appraiser will be directed to deliver an appraiser's
certificate (an "Appraiser's Certificate") to Grupo and Nextel Investment on or
before the 45th day (the "Certificate Date") after the last date by which Grupo
and Nextel Investment must designate an Appraiser pursuant to Section 3(a),
upon the conclusion of its evaluation, which appraiser's certificate shall set
forth such appraiser's determination hereunder of the Fair Cash Value.

                 (c)  Fair Cash Value Determination.  On the first Business Day
after the Certificate Date, the Fair Cash Value





                                       8
<PAGE>   9
shall be determined on the basis of the respective Appraisers' Certificates in
accordance with the provisions of this Section 3(c).  The higher of the values
set forth in the Appraisers' Certificates is hereinafter referred to as the
"Higher Value" and the lower of such values is hereinafter referred to as the
"Lower Value".  If the Higher Value is not more than 110% of the Lower Value,
the Fair Cash Value will be the arithmetic average of such two values.  If the
Higher Value is more than 110% of the Lower Value, a third Appraiser shall be
selected from Annex D to the Shareholders Agreement in accordance with the
provisions of Section 3(d) below, and the Fair Cash Value will be determined in
accordance with the provisions of Section 3(d) below.

                 (d)  Selection of and Procedure for Third Appraiser.  If the
Higher Value is more than 110% of the Lower Value, the Grupo Appraiser and the
Nextel Appraiser shall be directed by the Parties to jointly designate, within
seven days of the Certificate Date, by written notice to each Party a third
Appraiser from Annex D to the Shareholders Agreement (other than the Grupo
Appraiser and the Nextel Appraiser) to serve as an Appraiser pursuant to this
Section 3(d) (the "Third Appraiser").  The Parties shall direct the Third
Appraiser to determine in writing within 30 days after the selection of the
Third Appraiser, which Appraiser's Certificate more accurately states the Fair
Cash Value pursuant to Section 3(b) and the Fair Cash Value will be as set
forth in such Appraiser's Certificate.  Each of the Parties shall pay one-half
of the Third Appraiser's fees and expenses.

                 (e)  Conclusive Determination.  To the fullest extent
permitted by law, the determination of the Fair Cash Value made pursuant to
this Section 3 shall be final and binding on the Parties for purposes of this
Agreement.

                 (f)  Appraiser Procedures.  The Parties shall take all
reasonable action to cause the Issuer to provide each Appraiser with such
information concerning the Issuer as may be reasonably requested in writing by
each Appraiser for purposes of its evaluation hereunder.  Each Appraiser will
be obligated to keep confidential all information disclosed by the Issuer in
the course of conducting its evaluation and, to that end, to execute such
customary documentation as any Party or the Issuer may reasonably request with
respect to such confidentiality obligation.  The same information shall be
provided to the Grupo Appraiser and the Nextel Appraiser and all such
information shall be provided to the Third Appraiser.  The Appraisers may, but
shall be under no obligation to, consult with each other in the course of
conducting their respective evaluations.  Each Appraiser will be directed to
comply with the provisions of this Section 3, and to that end, the Parties will
provide the respective Appraisers with a complete and correct copy of this
Section 3 (and the definitions of capitalized terms used in this Section 3 that
are defined elsewhere in this Agreement).

                 Section 4.  Effective Date.  This Agreement shall be effective
from the first date by which a closing has occurred under both the Share
Purchase and Call Option Agreement and the Subscription Agreement.
Notwithstanding the foregoing, in the event that a Termination Offering or an
Alternate Offering has closed prior to January 1, 1999, or the Post-Transfer
Number with respect to Grupo and its Qualified Affiliates is less than 1% of
the outstanding Shares on the date of the Liquidity Request, then the Parties
shall have no obligations hereunder.

                 Section 5.  Governing Law. This Agreement shall be construed
and enforced in accordance with and shall be governed by the laws of the State
of New York, United States of America (including, without limitation, New York
General Obligations Law Section 5-1401) without giving effect to any choice of
law or conflict of law provision or rule (whether of New York or any other
jurisdiction) that would cause the application of the laws of any jurisdiction
other than the laws of the State of New York, except that Section 6 shall be
governed by and construed in accordance with the United States Federal
Arbitration Act and the 1958 United Nations Convention on the Recognition and
Enforcement of Foreign Arbitral Awards to the exclusion of any state or
municipal law of arbitration.  This Agreement may be translated into the
Spanish language, but if there is any inconsistency between the English and
Spanish versions hereof, the English version hereof shall be controlling.

                 Section 6.  Arbitration.  (a)  Except for obtaining a
temporary restraining order or preliminary injunction to prevent immediate
irreparable harm, any controversy, conflict or dispute of any nature that
arises in relation to this Agreement shall be settled exclusively and finally
by arbitration, which will be carried out in conformity with the Rules of
Conciliation and Arbitration of the International Chamber of Commerce (the
"ICC") in effect on the date of this Agreement (the "ICC Rules").  The
arbitration will be carried out by three arbitrators.  One arbitrator shall be
appointed by each side in accordance with Article 4.4 of the ICC Rules as if
each side were a "party" (as such term is used in Article 4.4 of the ICC Rules)
and the third arbitrator shall be selected by the two party-appointed
arbitrators or, failing agreement within 45 days after the notice of intention
to arbitrate is filed with the ICC (or such other period as may be agreed by
the two sides to such arbitration), by the ICC in accordance with the ICC
Rules; provided that any such third arbitrator selected by the ICC shall not be
a national of either the United States or Mexico.  Unless all of the parties to
such arbitration otherwise agree, all arbitrators appointed in any such
arbitration shall be bilingual in English and Spanish.

                 (b)      The arbitration will be carried out in Mexico D.F.,
Mexico, in the English language in conformity with the substantive law set
forth in Section 5 and the procedural rules set forth in this Section 6 and
Section 7 hereof; provided, however, that any party to the arbitration
proceeding with





                                       10
<PAGE>   11
reasonable prior notice to the other parties to such arbitration may submit
testimony or documentary evidence in Spanish, and shall, upon request of any
other party to the arbitration proceeding, furnish a translation into English
of any such testimony or documentary evidence.  Any translation of documentary
evidence shall be provided a reasonable period of time before its submission in
the proceeding.

                 (c)      At any oral hearing of evidence, each party to the
arbitration proceeding or its legal counsel shall have the right to examine its
witnesses and to cross-examine the witnesses of an opposing party.  No evidence
of any witness shall be presented in written form unless the opposing party or
parties shall have the opportunity to cross-examine such witness, except as the
parties to the arbitration proceeding otherwise agree in writing or except
under extraordinary circumstances where the interests of justice require a
different procedure.

                 (d)      Any decision or award of the arbitrators shall be
final and binding upon the parties to such arbitration, and judgment upon any
such arbitral award may be entered in any court of competent jurisdiction.  The
Parties hereby waive, to the fullest extent permitted by applicable law, any
rights to appeal or to review of such decision or award by any court or
tribunal.

                 (e)      To the extent that any Party has or hereafter may
acquire any immunity (sovereign or otherwise) from jurisdiction of any court or
from any legal process (whether through service or notice, attachment prior to
judgment, attachment in aid of execution, execution or otherwise) with respect
to itself or its property, each such Party hereby, to the fullest extent
permitted by applicable law, irrevocably waives such immunity in respect of its
obligations under this Agreement, in connection with any application for
judicial acceptance and an order of enforcement of any such decision or award.

                 Section 7.  Remedies.  It is agreed that irreparable damage
could occur in the event that Section 2(d) of this Agreement were not performed
in accordance with its specific terms or were otherwise breached and that in
addition to a party's right to seek a temporary restraining order or
preliminary injunction to prevent immediate irreparable harm, an arbitration
panel convened under Section 6 shall have the power to grant an injunction or
injunctions to prevent breaches of Section 2(d) and the parties shall be
entitled to enforce specifically the terms and provisions of an award of such
arbitration panel providing for such an injunction or injunctions in any such
court having jurisdiction, this being in addition to any other remedy to which
they are entitled at law or in equity.  All rights, powers and remedies
provided under this Agreement or otherwise available in respect hereof or at
law or in equity shall be cumulative and not alternative, and the exercise of
any thereof by any Party shall not preclude the simultaneous or later exercise
of any other such right, power or remedy by such Party.

2.       NONCOMPETITION

         Except for Gotesco Properties, Inc. or any Affiliate thereof
("Gotesco"), so long as any Stockholder owns any capital stock of the Company
or an Affiliate of the Company, such Stockholder or any Affiliate thereof shall
not in any way, by action or inaction, directly or indirectly, for itself or
for the benefit of any other Person, own, manage, operate, join or Control, or
participate in the ownership, management, operation or Control of, any Person
that competes with the Company or any Affiliate thereof, or agree to do any of
the foregoing in mobile telecommunications services in the Republic of the
Philippines for a period ending two years after the closing of the Company's
initial public offering; provided that any of the parties and its Affiliates
may invest in any such competitor whose securities are publicly traded to the
extent such investment by such party and its Affiliates in the aggregate does
not exceed 1% of the voting securities of any class of securities of such
party.  Without limiting the generality of the foregoing, any party shall be
deemed to be related to or connected with a Person that competes with the
Company or any Affiliate thereof if, among other things, such Person is (a) a
partnership in which such party is a general or limited partner, (b) a
corporation or association of which such party is a stockholder or for which a
director or officer of such party is an officer, employee or director, or (c) a
partnership, corporation or association for which such party is a consultant or
agent.  "Affiliate" of any Person (the "Subject") means any other Person that,
directly or indirectly, Controls or is Controlled by or is under common Control
with the Subject.  "Control" (including, with correlative meanings, the terms
"Controlled by" and "under common Control with"), as used with respect to any
Person, means the possession, directly or indirectly, of the power to direct or
cause the direction of the management and policies of such Person, whether
through the ownership of voting securities or by contract or otherwise.
"Person" means any individual, partnership, joint-stock company, firm,
corporation, association, unincorporated organization, joint venture, trust or
other entity.

3.       LOANS

         The Company shall use its best efforts to only enter into loan
agreements or other obligations on a nonrecourse basis.  However, to the extent
a Stockholder is required to provide a guaranty or other form of security to
support any loan or other obligation of the Company (a "Guaranty"), the
obligation of such Stockholder shall be several and not joint, and shall not
exceed such Stockholder's pro rata portion (as defined in Section 6.2)) of such
loan or other obligation.  For the purposes of this Section 3, in the event
such a Guaranty is necessary, William Ngai Wai Lun ("Ngai") hereby agrees to
provide such Guaranty on Gotesco's and its Affiliates' behalf to the full
extent of Gotesco's and its Affiliates' pro rata portion, such Guaranty to be
in addition to the Guaranty given by Ngai in relation to the pro rata portion
of Ngai and his Affiliates.

4.       REGISTRATION RIGHTS

         4.1     DEFINITIONS

                 For purposes of these registration rights:





                                     -2-
<PAGE>   3



                 (a)      The terms "register," "registered" and "registration"
refer to a registration effected by preparing and filing a registration
statement or similar document in compliance with the U.S. Securities Act of
1933, as amended (the  "Act"), and the declaration or ordering of effectiveness
of such registration statement or document;

                 (b)      The term "Registrable Securities" means any Common
Stock of the Company (the "Common Stock") issued as (or issuable upon the
conversion or exercise of any warrant, right or other security which is issued
as) a dividend or other distribution with respect to, or in exchange for or in
replacement of, such Common Stock, excluding in all cases, however, any
Registrable Securities sold by a person in a transaction in which its rights
under this Agreement are not assigned;

                 (c)      The number of shares of "Registrable Securities then
outstanding" shall be determined by the number of shares of Common Stock
outstanding which are, and the number of shares of Common Stock issuable
pursuant to then exercisable or convertible securities which are, Registrable
Securities;

                 (d)      The term "Holder" means any person owning or having
the right to acquire Registrable Securities who is a holder of Common Stock as
of the close of business on June 21, 1996; and

                 (e)      The term "Initiating Holders" means the Holders who
initiate the request for registration under section 4.2(a);

         4.2     REQUEST FOR REGISTRATION

                 (a)      If at any time after six months after the closing of
the Company's initial public offering, the Company shall receive a written
request from Holders of at least 30% of the Registrable Securities that the
Company file a registration statement under the Securities Act covering the
registration for an underwritten public offering of Registrable Securities with
estimated aggregate gross proceeds of at least $10,000,000, based on a
good-faith estimate of the market price of the Common Stock, then the Company
shall, within 10 days of the receipt thereof, give written notice of such
request to all Holders and shall, subject to the limitations contained in this
Section 4, effect the registration under the Securities Act of all Registrable
Securities which the Holders request to be registered by their giving written
notice to the Company within 20 days of the mailing by the Company of its
previous notice to the Holders.

                 (b)      The Initiating Holders must distribute the
Registrable Securities covered by their request by means of an underwritten
public offering.  The right of any Holder to include its Registrable Securities
in such registration shall be conditioned upon such Holder's participation in
such underwriting and the inclusion of such Holder's Registrable Securities in
the underwriting to the extent provided herein.  All Holders proposing to
distribute their securities through such underwriting shall (together with the
Company as provided in subsection 4.4(e)) enter into an underwriting agreement
in customary form with the underwriter or underwriters selected for such
underwriting by a majority in interest of the Initiating Holders, which
underwriter must also be reasonably acceptable to the Company.  Notwithstanding
any other provision of this Section 4.2,




                                     -3-
<PAGE>   4


if the underwriter advises the Company in writing that marketing factors
require a limitation of the number of shares to be underwritten, then the
Company shall so advise all Holders of Registrable Securities which would
otherwise be underwritten pursuant hereto, and the number of shares of
Registrable Securities that may be included in the underwriting shall be
allocated among all Holders thereof, including the Initiating Holders, in
proportion (as nearly as practicable) to the amount of Registrable Securities
of the Company owned by each Holder.

                 (c)      The Company is obligated to effect only one such
registration pursuant to this Section 4.2.

                 (d)      Notwithstanding the foregoing, if the Company shall
furnish to Holders requesting a registration statement pursuant to this Section
4.2, a certificate signed by the President of the Company stating that, in the
good faith judgment of the Board of Directors of the Company, it would be
seriously detrimental to the Company and its stockholders for such registration
statement to be filed and it is therefore essential to defer the filing of such
registration statement, the Company shall have the right to defer such filing
for a period of not more than 90 days after receipt of the request of the
Initiating Holders.

         4.3     COMPANY REGISTRATION

                 If (but without any obligation to do so) the Company proposes
to register (including for this purpose a registration effected by the Company
for stockholders other than the Holders) any of its stock or other securities
under the Act in connection with the public offering of such securities solely
for cash (other than a registration relating solely to the sale of securities
to participants in a Company stock plan, or a registration on any form that
does not include substantially the same information as would be required to be
included in a registration statement covering the sale of the Registrable
Securities), the Company shall, at each such time, promptly give each Holder
written notice of such registration.  Upon the written request of each Holder
given within 20 days after mailing of such notice by the Company, the Company
shall, subject to the provisions of Section 4.7, cause to be registered under
the Act all of the Registrable Securities that each such Holder has so
requested.

         4.4     OBLIGATIONS OF THE COMPANY

                 Whenever required under this Agreement to effect the
registration of any Registrable Securities, the Company shall, as expeditiously
as reasonably possible:

                 (a)      Prepare and file with the U.S. Securities and
Exchange Commission (the "U.S. SEC") a registration statement with respect to
such Registrable Securities and use its best efforts to cause such registration
statement to become effective, and, upon the request of the Holders of a
majority of the Registrable Securities registered thereunder, keep such
registration statement effective for up to 90 days.

                 (b)      Prepare and file with the U.S. SEC such amendments
and supplements to such registration statement





                                     -4-
<PAGE>   5


and the prospectus used in connection with such registration statement as may
be necessary to comply with the provisions of the Act with respect to the
disposition of all securities covered by such registration statement.

                 (c)      Furnish to the Holders such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the Act, and such other documents as they may reasonably
request in order to facilitate the disposition of all securities covered by
such registration statement.

                 (d)      Use its best efforts to register and qualify the
securities covered by such registration statement under such other  securities
or blue sky laws of such jurisdictions as shall be reasonably requested by the
Holders, provided that the Company shall not be required in connection
therewith or as a condition thereto to qualify to do business or to file a
general consent to service of process in any such states or jurisdictions.

                 (e)      In the event of any underwritten public offering,
enter into and perform its obligations under an underwriting agreement, in
usual and customary form, with the managing underwriter of such offering.  Each
Holder participating in such underwriting shall also enter into and perform its
obligations under such an agreement.

                 (f)      Notify each Holder of Registrable Securities covered
by such registration statement, at any time when a prospectus relating thereto
covered by such registration statement is required to be delivered under the
Act, of the happening of any event as a result of which the prospectus included
in such registration statement, as then in effect, includes an untrue statement
of a material fact or omits to state a material fact required to be stated
therein or necessary to make the statements therein not misleading in the light
of the circumstances then existing.

         4.5     FURNISH INFORMATION

                 It shall be a condition precedent to the obligations of the
Company to take any action pursuant to this Agreement that the selling Holders
shall furnish to the Company such information regarding themselves, the
Registrable Securities held by them and the intended method of disposition of
such securities as shall be reasonably required to effect the registration of
their Registrable Securities and to execute such documents in connection with
such registration as the Company may reasonably request.

         4.6     EXPENSES OF REGISTRATION

                 In connection with any registration pursuant to this
Agreement, the Company shall be responsible for the payment of all expenses of
the registration, with the exception of underwriting commissions and discounts
which shall be paid by the Company, the Holders and any other selling security
holders in proportion to the aggregate value of the securities offered for sale
by each of them.  Notwithstanding the preceding sentence, Holders participating
in a registration pursuant to Section 4.2 shall be responsible for the payment
of all expenses directly related to such registration.





                                     -5-
<PAGE>   6



         4.7     UNDERWRITING REQUIREMENTS

                 The Company shall not be required under Section 4.3 to include
any of the Holders' securities in an underwritten offering of the Company's
securities unless such Holders accept the terms of the underwriting as agreed
upon between the Company and the underwriters selected by it.  If the total
amount of securities, including Registrable Securities, requested by Holders to
be included in such offering exceeds the amount of securities that the
underwriters reasonably believe compatible with the success of the offering,
then the Company shall be required to include in the offering only that number
of such securities, including Registrable Securities, that the underwriters
believe will not jeopardize the success of the offering.  The securities to be
included in the registration in the event of such a reduction shall be
apportioned first to the Company, then pro rata among the selling Holders
according to the total amount of securities requested to be sold in such
registration by such Holders and then pro rata among any other selling Holders
according to the total amount of securities otherwise entitled to be included
therein owned by each such other selling Holder, or in such other proportions
as shall mutually be agreed to by such selling Holders.

         4.8     DELAY OF REGISTRATION

                 No Holder shall have any right to obtain or seek an injunction
restraining or otherwise delaying any such registration as the result of any
controversy that might arise with respect to the interpretation or
implementation of this Agreement.

         4.9     INDEMNIFICATION

                 In the event any Registrable Securities are included in a
registration statement under this Agreement:

                 (a)      To the extent permitted by law, the Company will
indemnify and hold harmless each Holder, the partners, officers, agents,
employees and directors of each Holder, any underwriter (as defined in the Act)
for such Holder and each person, if any, who controls such Holder or
underwriter within the meaning of the Act or the U.S. Securities Exchange Act
of 1934, as amended (the "1934 Act"), against any losses, claims, damages or
liabilities (joint or several) to which they may become subject under the Act,
the 1934 Act or other federal or state law, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are
based upon any of the following statements, omissions or violations
(collectively, a "Violation"): (i) any untrue statement or alleged untrue
statement of a material fact contained in such registration statement,
including any preliminary prospectus or final prospectus contained therein, in
light of the circumstances under which they were made, or any amendments or
supplements thereto, (ii) the omission or alleged omission to state therein a
material fact required to be stated therein, or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading, or (iii) any violation or alleged violation by the Company of
the Act, the 1934 Act, any state securities law or any rule or regulation
promulgated under the Act, the 1934 Act or any state securities law; and the
Company will reimburse each such Holder, partner, officer, agent, employee or
director, underwriter or controlling person for any legal or other expenses
reasonably incurred by them in connection with investigating or





                                     -6-
<PAGE>   7


defending any such loss, claim, damage, liability or action; provided, however,
that the indemnity agreement contained in this Section 4.9(a) shall not apply
to amounts paid in settlement of any such loss, claim, damage, liability or
action if such settlement is effected without the consent of the Company, which
consent shall not be unreasonably withheld, nor shall the Company be liable in
any such case for any such loss, claim, damage, liability or action to the
extent that it arises out of or is based upon a Violation occurring in reliance
upon and in conformity with written information furnished expressly for use in
connection with such registration by, or on behalf of, any such Holder,
underwriter or controlling person.

                 (b)      To the extent permitted by law, each selling Holder
will indemnify and hold harmless the Company, each of its  officers, directors,
agents or employees, each person, if any, who controls the Company within the
meaning of the Act, any underwriter and any other Holder selling securities in
such registration statement or any of its partners, officers, directors, agents
or employees or any person who controls such Holder, against any losses,
claims, damages or liabilities (joint or several) to which the Company or any
such officer, director, agent, employee, controlling person, or underwriter, or
other such Holder or its partner, officer, director, agent, employee or
controlling person may become subject, under the Act, the 1934 Act or other
federal or state law, insofar as such losses, claims, damages or liabilities
(or actions in respect thereof) arise out of or are based upon any Violation,
in each case to the extent (and only to the extent) that such Violation occurs
in reliance upon and in conformity with written information furnished by, or on
behalf of, such Holder expressly for use in connection with such registration;
and each such Holder will reimburse any legal or other expenses reasonably
incurred by the Company or any such partner, officer, director, agent,
employee, controlling person, underwriter or other such Holder, partner,
officer, director, agent, employee or controlling person in connection with
investigating or defending any such loss, claim, damage, liability or action;
provided, however, that the indemnity agreement contained in this Section
4.9(b) shall not apply to amounts paid in settlement of any such loss, claim,
damage, liability or action if such settlement is effected without the consent
of the Holder, which consent shall not be unreasonably withheld.

                 (c)      Promptly after receipt by an indemnified party under
this Section 4.9 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect
thereof is to be made against any indemnifying party under this Section 4.9,
deliver to the indemnifying party a written notice of the commencement thereof,
and the indemnifying party shall have the right to participate in, and, to the
extent the indemnifying party so desires, jointly with any other indemnifying
party similarly notified, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the fees and expenses to be paid
by the indemnifying party, if, in the opinion of counsel for the indemnifying
party, representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by
such counsel in such proceeding.  The failure to deliver written notice to the
indemnifying party within a reasonable period of time of the commencement of
any such action shall relieve such indemnifying party of any liability to the
indemnified party under this Section 4.9 to the extent prejudicial to its
ability to defend such action, but the omission so to deliver written notice to
the indemnifying party will not relieve it of any liability that it may have to
any indemnified party otherwise than under this Section 4.9.

         4.10    "MARKET STAND-OFF" AGREEMENT

         The Holders hereby agree that they shall not, to the extent requested
by the Company and an underwriter of Common Stock (or other securities) of the
Company, sell or otherwise transfer or dispose of (other than to donees who
agree to be similarly bound) any Registrable Securities for 180 days following
the effective date of a registration statement of the Company filed under the
Act; provided, however, that all officers and directors of the Company and all
other persons with registration rights (whether or not pursuant to this
Agreement) enter into similar agreements.

         In order to enforce the foregoing covenant, the Company may impose
stop-transfer instructions with respect to the Registrable Securities of the
Holders (and the shares or securities of every other person subject to the
foregoing restriction) until the end of such period.

         4.11    RIGHT TO TERMINATE REGISTRATION

         The Company shall have the right to terminate or withdraw any
registration initiated by it under this Section 4 prior to the effectiveness of
such registration whether or not any Stockholder has elected to include
securities in such registration.

         4.12    PHILIPPINE REGISTRATION RIGHTS

         To the extent necessary for the public sale of shares of Common Stock
under or permitted by Philippine law (or the law of any other jurisdiction the
Company elects), the Company shall provide the Stockholders substantially
similar rights to those provided by this Section 4 with respect to the
Company's public offering of Common Stock in the Philippines (or such other
jurisdiction), if the Company elects to make such offerings.

5.       RESTRICTIONS ON TRANSFER

         5.1     TRANSFERS

         Except as otherwise provided in the Articles of Incorporation or
By-laws, Stockholders may not sell, assign, transfer, pledge, hypothecate,
mortgage, encumber or dispose of (collectively, "Transfer") all or any part of
any shares of Common Stock or other securities of the Company convertible into
Common Stock (collectively, the "Shares") unless such Stockholder has complied
with the provisions of this Section 5.

         5.2     OFFER BY A STOCKHOLDER

         If a Stockholder of the Company desires to sell, assign, transfer,
pledge, hypothecate, mortgage, encumber or dispose of (collectively,
"Transfer") any or all of its Shares (the "Offered Shares") pursuant to a bona
fide offer received by such Stockholder (the "Selling Stockholder") from a
third party, it shall make a written offer to sell the Offered Shares (the
"Offer") to all other Stockholders.  A statement attached to the Offer shall
set forth a full disclosure of the Offer, including (a) a statement of
intention to Transfer, (b) the name and address of the prospective transferee,
(c) the number of Offered Shares and (d) the terms and conditions of the
Transfer, including the purchase price for the Offered Shares.





                                     -8-
<PAGE>   9



         5.3     ACCEPTANCE OF OFFER

         Within 30 days after its receipt of the Offer, each Stockholder (a
"Purchasing Stockholder") may elect to  purchase, at the price and on the terms
specified in the Offer, such number of Offered Shares equal to its pro rata
portion (as defined below) of the Common Stock by giving written notice to the
Selling Stockholder and to the other Stockholders of the number of shares that
such Purchasing Stockholder is electing to purchase.  If any Stockholder or
Stockholders elect not to purchase all or any part of its or their pro rata
portion of the Offered Shares, each Purchasing Stockholder may elect to
purchase within five days after such 30th day such portion of the Offered
Shares that such Stockholder or Stockholders elected not to purchase equal to
such Purchasing Stockholder's pro rata portion.

         The closing of such purchase shall occur on a date mutually acceptable
to the parties thereto within 30 days after such acceptance.  At such closing,
the Purchasing Stockholders shall pay the Selling Stockholder the purchase
price in accordance with Section 5.2(d), and the Selling Stockholder shall
simultaneously deliver the certificates representing the shares being
transferred and all other evidence of transfer as may reasonably be requested
by the transferee.

         5.4     OFFER NOT ACCEPTED

         If any of the Offered Shares remain unpurchased following the time
periods specified above, the Selling Stockholder may Transfer such remaining
Offered Shares to the prospective transferee named in the statement attached to
the Offer as provided in Section 5.2, such transfer to be made only in strict
accordance with the terms set forth in such statement and to be completed
within 90 days following the expiration of the time provided for the purchase
of the Offered Shares by the Purchasing Stockholders, after which time any such
transfer shall again become subject to all the restrictions of this Agreement,
the By-laws and the Articles of Incorporation.  The transferee shall agree in
writing to be bound by the terms of this Agreement.

         5.5     NO OTHER TRANSFER EFFECTIVE

         No Transfer of any right, title or interest in the Shares shall be
effective, and the Company shall not record or recognize any such Transfer,
until there has been compliance with the provisions of this Agreement, the
By-laws and the Articles of Incorporation.  If no Offer is made as herein
required, the Company and the Stockholders may nevertheless exercise their
rights hereunder as to the transferred Shares, and they may do so at any time,
even after the purported Transfer of the Shares.

         5.6     FURTHER RESTRICTIONS ON TRANSFER

         Prior to the initial public offering of Common Stock, no Stockholder
which is a partnership, joint-stock company, corporation, association,
unincorporated organization, joint venture, trust or other entity (other than
Gotesco Corporation) may Transfer, in one or more transactions, more than 40%
of its own capital stock to any person other than one of its Affiliates;
provided, however, this Section 5 shall not apply in the case of any Transfer
by MIL pursuant to which (a) Craig McCaw shall no longer Control Nextel
Communications, Inc., a Delaware





                                     -9-
<PAGE>   10


corporation and an Affiliate of McCaw International, Ltd., a Washington
corporation ("MIL"), or (b) the management of MIL retains substantially the
same operational and management control over MIL.

6.       COSALE PROVISIONS

         6.1     RIGHT OF PARTICIPATION

         In addition to the rights under Section 5, if Stockholders holding
more than 51% of the outstanding Common Stock (the "Transferring Stockholders")
propose to transfer 51% or more of the outstanding Common Stock to any third
party, such Transferring Stockholders shall provide written notice to all other
Stockholders (the "Remaining Stockholders") setting forth (a) a statement of
intent to transfer, (b) the name and address of the prospective transferee, (c)
the number of shares of Common Stock proposed to be transferred, and (d) the
terms and conditions of the transfer, including the proposed purchase price.
The Remaining Stockholders shall have the right, as a condition to any transfer
by the Transferring Stockholders, to transfer to any purchaser of the offered
Common Stock a pro rata portion (as defined below) of its Common Stock at the
same price per share and on the same terms and conditions as stated in the
notice of the Transferring Stockholder.  If and to the extent that any
Remaining Stockholder exercises its rights under this Section 6.1, the offered
Common Stock of the Transferring Stockholders shall be reduced and the Common
Stock being sold by the Remaining Stockholders shall be substituted therefor.

         6.2     PRO RATA PORTION

         For purposes of this Agreement, a Stockholder's pro rata portion shall
be the proportion that the number of shares of Common Stock such Stockholder
owns or Controls immediately prior to the time of calculation bears to the
total number of Shares of Common Stock outstanding (including in each case
shares of Common Stock and Common Stock issuable upon the conversion of
convertible securities (other than options) of the Company).

         6.3     STOCKHOLDER'S NOTICE

         If any Remaining Stockholder wishes to exercise its rights under this
Section 6 to participate in a Transfer, it shall notify the Transferring
Stockholders in writing of such intention as soon as practicable after its
receipt of the notice pursuant to Section 6.1, and in any event within 30 days
after the date of such notice.  Such notification of exercise shall be
delivered in person or mailed to the Transferring Stockholders at the address
set forth on the signature pages hereto.

7.       CREATION OF SEPARATE CLASS OF STOCK

         The Stockholders shall vote in favor of amendments to the Company's
Articles of Incorporation and Bylaws to create a separate class of stock (the
"Gotesco Stock") which shall be offered to Gotesco and its Affiliates in
exchange for shares of Common Stock owned by them.  The Gotesco Stock shall not
be subject to the restrictions on transfer set forth in Sections 5 and 6 (the
"Restrictions") of this Agreement, but shall otherwise have the same rights,
privileges,


                                    -10-
<PAGE>   11
preferences and restrictions as the Common Stock.  The Stockholders shall also
vote in favor of amendments to the Company's Articles of Incorporation and
By-laws which shall make the Restrictions applicable to all shares of Common
Stock other than the Gotesco Stock.

8.       MISCELLANEOUS

         8.1     TERM

         This Agreement shall terminate on the fifth anniversary hereof and

Mr. Keith Grinstein
2345 43rd Avenue East
Seattle, WA 98112
Dear Keith:

         We are very pleased to offer you a position with McCaw International,
Ltd. ("McCaw International") as its President and Chief Executive Officer to be
based in Kirkland, Washington.

         Outlined below are the terms and conditions regarding the offered
position:

         -   Your employment with McCaw International will start on or about
             January 1, 1996.

         -   Your beginning compensation will be a salary of $150,000 per year
             and will be subject to review through an annual performance
             evaluation.  You will be paid bi-monthly, with paychecks delivered
             to you one week following the end of the pay period.  Your next
             performance review for salary adjustment will be in January of
             1997.

         -   You will be eligible to receive an annual bonus, determined at
             year-end based upon your performance against objectives.  We will
             work together to mutually determine those objectives within 30
             days of your start date.  McCaw International recognizes that in
             the first two years it will be difficult to measure performance
             objectively and we will gauge our criteria for those year's
             performance objectives accordingly.  This bonus is paid in the
             month of January for the prior year's performance.  You will have
             no bonus for any portion of calendar year 1995.

         -   You will be President and Chief Executive Officer of McCaw
             International, reporting as specified from time to time by the
             Board of Directors of McCaw International; although you will
             remain subject to the direction and control of the Board of
             Directors of

             McCaw International and will report directly to such Board on a
             periodic basis for such purposes, initially you also will have a
             reporting relationship to the Operations Committee of the Board of
             Directors of Nextel Communications, Inc.  ("Nextel"), the ultimate
             parent of McCaw International, in connection with such Operations
             Committee's role in developing and assessing the overall
             international business strategy and plan for the Nextel
             consolidated group.

         -   You will be awarded options to acquire shares of the Class A
             Common Stock ("Shares") of Nextel in accordance with the Option
             Plan of Nextel.  These options constitute qualified options under
             the Internal Revenue Code.  The number of options which you will
             be granted will be at the market price as of close on the later of
             the date on which your employment was agreed and the date your
             option grant is approved by the Nextel Compensation Committee, and
             the number of the options you will receive is 50,000.  These
             options will vest over 4 years in accordance with the Nextel
             Option Plan.

         -   You will receive a Stock Appreciation Right in McCaw International
             in accordance with a Stock Appreciation Right Plan for McCaw
             International which has yet to be documented but which shall be in
             accordance with mutually acceptable terms.  The number of SARs
             which you will receive is 400,000 at par.  They will vest over 4
             years on a prorated monthly basis commencing upon employment.  The
             SAR Plan will contemplate a grant to you of all appreciation in
             the units that you receive, over and above a prime plus two
             interest rate.  While the number of units that you have will not
             be diluted, you realize that as additional equity is injected into
             McCaw International, your percentage SAR interest will decline.

         -   The initial term of your employment with McCaw International shall
             terminate June 30, 1997, and shall automatically be renewed for a
             subsequent one year term commencing July 1, 1997 unless during
             December 1996 either party elects by written notice not to renew.

             If you are terminated (or not renewed) other than for cause by
             McCaw International, you will receive (upon and assuming your
             execution of a suitable claims release in favor of McCaw
             International) a termination payment equal to (a) salary for the
             remaining initial term of your

             employment but (b) no less than 6 months salary and in either case
             excluding bonus but including Cobra rights.

         -   So long as your employment with McCaw International continues and
             McCaw International continues to be a subsidiary of Nextel, you
             will be eligible to participate in the on going Nextel Option
             Program.  The current Nextel Option Plan is as described in a
             brochure which I have not yet had a chance to obtain, but which I
             will give you as soon as I do obtain it.  It will change in an
             undetermined fashion soon, however, and may not reflect the
             current terms of the plans; additionally, it may be amended from
             time to time or terminated by Nextel.

         -   You will be eligible to receive the benefits package offered by
             McCaw International, a summary of which is attached.  McCaw
             International reserves the right to alter this benefit package at
             any time.

         -   You will accrue vacation with pay at a rate of 20 days per year.

         Keith, we believe that you will make a valuable addition to our team
and look forward to working with you.  Please don't hesitate to contact me if

          While the number of units that you have will not be diluted, you

          terminate June 30, 1997, and shall automatically be renewed for a
          subsequent one year term commencing July 1, 1997 unless during

          If you are terminated (or not renewed) other than for cause by

          McCaw International, you will receive (upon and assuming your
          execution of a suitable claims release in favor of McCaw
          International) a termination payment equal to (a) salary for the
          remaining initial term of your employment but (b) no less than 6
          months salary and in either case excluding bonus but including Cobra
          rights.

     -    So long as your employment with McCaw International continues and
          McCaw International continues to be a subsidiary of Nextel you will
          be eligible to participate in the on going Nextel Option Program
          which has been described to you by Tom Sidman in oral terms.  The

                                   injected into McCaw International, your

                                   Committee and the Board of Directors of the
                                   Company have acted and specific terms and
                                   provisions of the plans have been approved.

Termination:                       The initial term of your employment with the
                                   Company shall be one year from the date you
                                   start.  Thereafter, your employment with
                                   McCaw International will be of indefinite
                                   duration, terminable at will by either
                                   party, without cause.  This means that you
                                   may elect to terminate your employment with
                                   McCaw International at any time, and McCaw
                                   International retains the same rights.  This
                                   "employment at-will" paragraph operates
                                   notwithstanding any other provision of this
                                   letter, and no officer or employee of McCaw
                                   International is authorized to offer any
                                   employment relationship other than the
                                   "at-will" relationship provided for in this
                                   paragraph.  If either party terminates this
                                   Agreement, except for COBRA benefits and
                                   repatriation, all rights and liabilities
                                   hereunder will cease.  You and McCaw
                                   International agree that the terms of your
                                   employment will be governed by the laws of
                                   the State of Washington, not by the laws of
                                   any foreign country.

                                   If prior to the first anniversary of your
                                   commencing employment with the Company you
                                   elect to terminate your employment without
                                   cause, you agree to reimburse the Company
                                   for that portion of the out-of-pocket
                                   expenses the Company has incurred in
                                   connection with relocating you, your family
                                   and your personal goods and effects to
                                   Seattle, as well as any storage costs which
                                   is derived by dividing the number of days
                                   remaining until the first anniversary of
                                   your commencement of employment by 365.

Relocation Expenses:               McCaw International will pay for the cost of

                                   figure is neither a ceiling nor minimum

                                   with a Stock Appreciation Rights Plan from
                                   McCaw International.  The number of SARs
                                   which you will receive is 50,000 at par.
                                   They will vest over four years on a

                                   be diluted, you must realize that as

                                   International, your percentage SAR interest
                                   will decline.

                          MCCAW INTERNATIONAL, LTD.
                                      
                            1997 STOCK OPTION PLAN
                                      
                            SECTION 1.     PURPOSE

         The purpose of this McCaw International, Ltd. 1997 Stock Option Plan
(this "Plan") is to provide a means whereby selected employees, directors,
officers, consultants, agents, advisors and independent contractors of McCaw
International, Ltd., a Washington corporation (the "Company"), and its
Subsidiaries (as defined in Section 4) may be granted options to purchase
shares of the common stock of the Company (the "Common Stock") and thereby
share in any future appreciation in the value of the Common Stock.

                         SECTION 2.     ADMINISTRATION

         This Plan shall be administered by the Board of Directors of the
Company (the "Board") or a committee designated by the Board in its discretion,
which must include two or more members of the Board.  If and so long as the
Common Stock is registered under Section 12(b) or 12(g) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), the Board shall consider
in selecting the Plan Administrator and the membership of any committee acting
as Plan Administrator, with respect to any persons subject or likely to become
subject to Section 16 of the Exchange Act, the provisions regarding (a)
"outside directors" as contemplated by Section 162(m) of the Internal Revenue
Code of 1986, as amended (the "Code"), and (b) "nonemployee directors" as
contemplated by Rule 16b-3 under the Exchange Act.  The Board may delegate the
responsibility for administering this Plan with respect to designated classes
of eligible persons to different committees consisting of two or more members
of the Board, subject to such limitations as the Board deems appropriate.
Committee members shall serve for such term as the Board may determine, subject
to removal by the Board at any time.  The Board (or the designated committee,
if applicable) shall hereinafter be referred to as the "Plan Administrator."
The Board may also authorize a senior executive officer of the Company to
administer this Plan within limits specifically prescribed by the Board.
Except for the terms and conditions explicitly set forth in this Plan, the Plan
Administrator shall have the authority, in its discretion, to determine all
matters relating to the options to be granted under this Plan, including
selection of the individuals to be granted options, the number of options to be
granted, and all other terms and conditions of the options.  The options
granted under this Plan need not be identical in any respect, even when made
simultaneously.

   
                                   PAGE 1     
    
                                   
<PAGE>   2
         The Plan Administrator shall be responsible for interpreting and
construing the terms and provisions of this Plan, any options issued hereunder,
or any rule or regulation promulgated in connection with this Plan and
associated options.  All actions of the Plan Administrator shall, to the
maximum extent permitted under law, be determined in its good faith discretion,
and subject to appeal or dispute only as to its failure to adhere to such good
faith discretion standard.  Any party disagreeing with the Plan Administrator's
interpretation or decision may request the Plan Administrator to reexamine its
action.  A request for a reexamination must be made in writing within 60 days
of the Plan Administrator's decision or action, and must specify the reasons
why the Plan Administrator's decision or action was wrong or inappropriate.
Within 90 days of its receipt of a request to reexamine a decision or action,
the Plan Administrator will respond in writing to the disputing party.  The
Plan Administrator's response shall either reverse or reconfirm its initial
decision or action.  If the response reconfirms the initial decision or action,
the Plan Administrator shall state why it disagrees with the points raised by
the disputing party.

         A continuing dispute between the Plan Administrator and a recipient of
options about the proper interpretation of this Plan or the Stock Purchase
Agreement to be entered into between the Company and the holder of an option
upon exercise of an option (the "Stock Purchase Agreement"), or the correct
amount of benefits available under this Plan or the Stock Purchase Agreement
shall be settled in Seattle, Washington, or such other location reasonably
selected by the Company, by arbitration in accordance with the procedures
utilized by Commercial Arbitration Rules of the American Arbitration
Association (the "AAA Rules").  The arbitrator shall be either selected by the
mutual agreement of the parties or chosen in accordance with the AAA Rules.
Judgment upon the award rendered by the arbitrator may be entered in any court
having jurisdiction thereof.  Notwithstanding anything in the AAA Rules to the
contrary, the prevailing parties shall not be entitled to costs, expenses or
attorneys' fees.

                   SECTION 3.     STOCK SUBJECT TO THIS PLAN

3.1      AUTHORIZED NUMBER OF SHARES

   
         Subject to adjustment from time to time as provided in Section 7, a
maximum of $1,825,000 shares of Common Stock shall be available for
issuance under this Plan.  Shares issued under this Plan shall be drawn from
authorized and unissued shares or shares now held or subsequently acquired by
the Company.
    

3.2      REUSE OF SHARES

         Any shares of Common Stock that have been made subject to an option
that cease to be subject to the option (other than by reason of exercise of the
option to the extent it is exercised for shares) shall again be available for
issuance in connection with future grants of options under this Plan.

<PAGE>   3
                         SECTION 4.     ELIGIBILITY

         An option may be granted to any employee, director, officer,
consultant, agent, advisor or independent contractor of the Company or its
Subsidiaries that the Plan Administrator from time to time selects.  For
purposes of this Plan, except as provided below, the term "Subsidiary" means
any entity that is directly or indirectly controlled by the Company or in which
the Company has a significant ownership interest, as determined by the Plan
Administrator.  In addition, an option may be granted to any person who was
granted a stock appreciation right under the Company's Stock Appreciation
Rights Plan and who is an employee of Nextel Communications, Inc. ("Nextel") on
the date of grant.  Anyone to whom an option is granted under this Plan shall
be referred to hereinafter as an "Optionee."

         Notwithstanding anything in this Plan to the contrary, the Plan
Administrator may grant options under this Plan in substitution for awards
issued under other plans, or assume under this Plan awards issued under other
plans, if the other plans are or were plans of other acquired entities
("Acquired Entities") (or the parent of the Acquired Entity) and the new option
is substituted, or the old award is assumed, by reason of a merger,
consolidation, acquisition of property or of stock, reorganization or
liquidation (the "Acquisition Transaction").  In the event that a written
agreement pursuant to which the Acquisition Transaction is completed is
approved by the Board and said agreement sets forth the terms and conditions of
the substitution for or assumption of outstanding awards of the Acquired
Entity, said terms and conditions shall be deemed to be the action of the Plan
Administrator without any further action by the Plan Administrator, except as
may be required for compliance with Rule 16b-3 under the Exchange Act, and the
persons holding such awards shall be deemed to be Optionees.

                 SECTION 5.     TERMS AND CONDITIONS OF OPTIONS

         The Plan Administrator shall have the authority, in its sole
discretion, to determine the awards to be made under this Plan.  Such awards
shall consist of incentive stock options that are intended to qualify under
Section 422 of the Code or nonqualified stock options.

         Options granted under this Plan shall be evidenced by individual
written agreements ("option letter agreements"), which shall contain such
terms, conditions, limitations and restrictions as the Plan Administrator shall
deem advisable and consistent with this Plan.  Notwithstanding the foregoing,
all options shall include or incorporate by reference the following terms and
conditions, except as provided otherwise in the applicable option letter
agreement:

<PAGE>   4
5.1      NUMBER OF OPTIONS AND EXERCISE PRICE

         At the time a grant of an option is made, the Plan Administrator shall
establish the maximum number of shares of Common Stock subject to the option
contained in the grant.  Also at the time an option is granted, the
corresponding option letter agreement shall designate the exercise price for
shares purchased under the option, which shall be as determined by the Plan
Administrator, but shall not be less than 100% of the fair market value (as
determined below) of a single share of Common Stock on the date of grant with
respect to incentive stock options.

5.2      DETERMINATION OF FAIR MARKET VALUE

         The per share fair market value shall be established by the Plan
Administrator as follows:

         5.2.1

         Within 90 days following the close of the Company's fiscal year, the
Plan Administrator shall establish the fair market value of a share of the
Common Stock for purposes of this Plan, based on financial data dated as of the
end of the most recently closed fiscal year, and shall deliver written notice
of such value to each Optionee within a reasonable period of time of
determining such value (the "Year-End Valuation Notice").  Within 90 days
following the close of the second fiscal quarter of the Company's fiscal year,
the Plan Administrator shall establish the per share fair market value of a
share of the Common Stock for purposes of this Plan, based on financial data
dated as of the end of the second quarter of the fiscal year, and shall deliver
written notice of such value to each Optionee within a reasonable period of
time of determining such value (the "Six-Month Valuation Notice") (the Year-End
Valuation Notice and the Six-Month Valuation Notice are each a "Valuation
Notice").  For purposes of determining the per share fair market value of the
Common Stock on a date other than during a Semi-Annual Exercise Period (as
defined in Section 5.4 below) each year, the Plan Administrator shall determine
the per share fair market value of a share of the Common Stock in good faith,
consistently using formulas and other valuation techniques generally used in
purchasing and selling business similar to the Company.  The determination of
fair market value by the Plan Administrator shall be conclusive and binding on
all parties; provided, in the event of a dispute over the valuation, the
arbitration process discussed in Section 2 shall not affect or alter the Plan
Administrator's determination if the arbitrator concludes the Plan
Administrator (i) acted in good faith and (ii) based its determination on
formulas and other valuation techniques generally used in the purchase and sale
of businesses similar to the Company.

<PAGE>   5
         5.2.2

         Notwithstanding the preceding paragraph of this Section 5.2, in the
event the grant and/or exercise of options or the exercise of certain put
rights to sell to the Company shares acquired upon exercise of an option (a
"Put Right") as described in Section 12.2 occurs in connection with the sale of
the Company, an initial public offering, merger, or other similar event that
utilizes or produces a purchase value for the Company or for individual shares
of the Common Stock, then that value shall be used for computing the per share
fair market value under this Plan.

         5.2.3

         Notwithstanding the foregoing, if the Common Stock is listed on the
Nasdaq National Market, the per share fair market value shall be the average of
the high and low per share sales prices for the Common Stock as reported by the
Nasdaq National Market for a single trading day or, if the Common Stock is
listed on the New York Stock Exchange or the American Stock Exchange, the per
share fair market value shall be the average of the high and low per share
sales prices for the Common Stock as such price is officially quoted in the
composite tape of transactions on such exchange for a single trading day.  If
there is no such reported price for the Common Stock for the date in question,
then such price on the last preceding date for which such price exists shall be
determinative of the per share fair market value.

5.3      TERM AND VESTING

         The term of each option shall be ten years from the date of grant,
unless a different term is established by the Plan Administrator and set forth
in the option letter agreement issued to the individual Optionee.  The Plan
Administrator may, in its discretion, extend the term period of an option.  In
addition, the term of an option shall expire, if earlier than ten years or the
different term specified in the option letter agreement, earlier in accordance
with the provisions of Section 5.8 if the Optionee's employment or service
relationship with the Company terminates before the end of ten years from the
date of grant or the different term specified in the option letter agreement.
To the extent not exercised within the applicable time period provided herein,
options shall become null and void.

         To ensure that the Company achieves the purpose and receives the
benefits contemplated in this Plan, any option granted to any person hereunder
shall, unless the condition of this sentence is waived or modified by the Plan
Administrator in the individual option letter agreement or at any later time,
vest on a monthly basis over a four-year period, with the Optionee becoming
vested in 1/48th of the option grant after the completion of each full calendar
month of employment or service relationship with the Company following the date
as of which the option was granted.

<PAGE>   6
5.4      EXERCISE

         After an Optionee becomes at least 50% vested with respect to any
single option grant, the Optionee may exercise vested options included in that
grant; provided that, an Optionee may not exercise more than 20% of the options
conveyed in a specific grant in a single fiscal year of the Company.  This 50%
threshold shall apply separately to each separate grant of options.  The Plan
Administrator may in its discretion increase the percentage of options which
may be exercised.  To the extent options are exercised upon a termination of
employment or service relationship with the Company (as described in Section
5.8), the preceding 50% and 20% limits shall not apply.  During an Optionee's
lifetime, any options granted under this Plan are personal to him or her and
may be exercised solely by such Optionee except as permitted under Section 5.7.

         To the extent that the right to purchase shares has accrued
thereunder, an option may be exercised only during a Semi-Annual Exercise
Period by delivering during such Semi-Annual Exercise Period written notice to
the Company, in accordance with procedures established by the Plan
Administrator, setting forth the number of shares with respect to which the
option is being exercised and accompanied by payment in full as described
below.  "Semi-Annual Exercise Periods" means the 30-day periods commencing each
year on each of the dates the Plan Administrator delivers to the Optionee the
Year-End Valuation Notice and the Six-Month Valuation Notice pursuant to
Section 5.2.1, during which periods an Optionee is entitled to exercise his or
her options pursuant to the terms hereof.

         The limitations on exercisability contained in this Section 5.4 shall
not apply at any time during which the Common Stock is registered under Section
12(b) or 12(g) of the Exchange Act.  The Plan Administrator may determine at
any time that an option may not be exercised as to less than 100 shares at any
one time (or the lesser number of remaining shares covered by the option).

5.5      PAYMENT OF THE EXERCISE PRICE

         The exercise price for shares purchased under an option shall be paid
in full to the Company by delivery of consideration equal to the product of the
option exercise price and the number of shares purchased.  Such consideration
must be paid in cash or by check or, unless the Plan Administrator in its sole
discretion determines otherwise, either at the time the option is granted or at
any time before it is exercised, a combination of cash and/or check (if any)
and any of the following alternative forms: (a) tendering (either actually or,
if and so long as the Common Stock is registered under Section 12(b) or 12(g)
of the Exchange Act, by attestation) Common Stock already owned by the Optionee
for at least six months (or any shorter period necessary to avoid a charge to
the Company's earnings for financial reporting purposes) having a fair market
value on the day prior to the exercise date equal to the aggregate option
exercise price; or (b) if and so




   
                                   PAGE 6                             
    
                               
<PAGE>   7
long as the Common Stock is registered under Section 12(b) or 12(g) of the
Exchange Act, delivery of a properly executed exercise notice, together with
irrevocable instructions, to (i) a brokerage firm designated by the Company to
deliver promptly to the Company the aggregate amount of sale or loan proceeds
to pay the option exercise price and any withholding tax obligations that may
arise in connection with the exercise and (ii) the Company to deliver the
certificates for such purchased shares directly to such brokerage firm, all in
accordance with the regulations of the Federal Reserve Board.  In addition, the
price for shares purchased under an option may be paid, either singly or in
combination with one or more of the alternative forms of payment authorized by
this Section 5.5, by such other consideration as the Plan Administrator may
permit.

5.6      STOCK PURCHASE AGREEMENT

         Prior to and as a condition to the exercise of an option, the Optionee
shall become a party to and agree to the terms of a Stock Purchase Agreement,
which agreement provides terms and conditions regarding the ownership and
disposition of the Common Stock issued upon the exercise of an option.  A copy
of the Stock Purchase Agreement, in its substantial form, shall be provided to
the Optionee upon the grant of an option to the Optionee.

5.7      NON-TRANSFERABILITY OF OPTIONS

         Options granted under this Plan and the rights and privileges
conferred thereby may not be transferred, assigned, pledged or hypothecated in
any manner (whether by operation of law or otherwise) other than by will or by
the applicable laws of descent and distribution, and shall not be subject to
execution, attachment or similar process.  Upon any attempt to transfer,
assign, pledge, hypothecate or otherwise dispose of any option under this Plan
or of any right or privilege conferred thereby, contrary to the provisions
hereof, or upon the sale or levy or any attachment or similar process upon the
options or rights and privileges conferred thereby, such option shall terminate
and become null and void.  Notwithstanding the foregoing, and to the extent
permitted by Section 422 of the Code, the Plan Administrator, in its sole
discretion, may permit the assignment or transfer of an option and may permit
an Optionee to designate a beneficiary who may exercise the option after the
Optionee's death; provided, however, that any option so assigned or transferred
shall be subject to all the same terms and conditions contained in the option
letter agreement.

5.8      TERMINATION OF EMPLOYMENT OR SERVICE RELATIONSHIP WITH THE COMPANY

         If the Optionee terminates his or her employment or service
relationship with the Company for any reason (including retirement, death,
disability or otherwise), the Optionee may exercise the vested portion of his
or her options, as governed by the vesting schedule defined in Section 5.3.
The unvested portion of his or her options shall be forfeited.  In addition, an
Optionee whose employment or service relationship with the





   
                                   PAGE 7                             
    
                                   
<PAGE>   8
Company is terminated for cause shall forfeit all outstanding options,
including vested and unvested portions.  A termination shall be considered for
"cause" if the Plan Administrator determines that the Optionee's termination of
employment or service relationship with the Company was for one of the
following reasons:  (a) proven embezzlement by the Optionee of the Company's
assets, or other crimes by the Optionee against or directly involving the
Company's property; (b) material violation by the Optionee, whether or not an
employee, of the policies applicable to employees of the Company; (c) the
Optionee acting in any fashion as an independent consultant or employee, for
himself or herself or any other business or employer other than the Company, in
any endeavor that in any way competes with the Company; or (d) the Optionee's
willful engaging in conduct that is materially injurious to Nextel, the Company
or their subsidiaries, financially or otherwise.  For purposes of this Section
5.8, no act, or failure to act, on the Optionee's part shall be considered
"willful" unless done, or omitted to be done, by the Optionee not in good faith
and without reasonable belief that such action or omission was in the best
interest of Nextel, the Company or their subsidiaries.

         The portion of the Optionee's options that are vested and
nonforfeitable on the date of the Optionee's termination of employment or
service relationship with the Company for any reason other than total
disability or death may be immediately exercised for a period of 90 days
following the Optionee's termination of employment or service relationship with
the Company.  If termination of employment or service relationship with the
Company is due to an Optionee's total disability (as defined in Section
5.12.4), then the right to exercise the Optionee's vested and nonforfeitable
options under this Section 5.8 shall extend to one year from the date of
termination of employment or service relationship.  If termination of
employment or service relationship with the Company is due to an Optionee's
death (or the Optionee dies within 90 days following a termination of
employment or service relationship with the Company, but prior to exercising
his or her options), then the right to exercise the Optionee's vested and
nonforfeitable options under this Section 5.8 shall pass to the Optionee's
personal representative or estate, and the period for exercise shall extend to
one year from the date of death.  The Plan Administrator, may, in its
discretion, waive or extend these exercise periods.  Following these exercise
periods, any remaining unexercised options shall automatically terminate and be
forfeited.

         For purposes of this Section 5.8, employment or service relationship
with the Company shall be deemed to continue while the Optionee is on military
leave, sick leave or other bona fide leave of absence (as determined by the
Plan Administrator).  The foregoing notwithstanding, employment or service
relationship with the Company shall not be deemed to continue beyond the first
90 days of such leave, unless the Optionee's reemployment rights are guaranteed
by statute or contract.

5.9      CONTINUATION OF EMPLOYMENT OR SERVICE RELATIONSHIP WITH THE COMPANY

         Nothing in this Plan or in any options granted pursuant to this Plan
shall confer upon any Optionee any right to continue in the employment or
service relationship of the Company or of any Subsidiary, or to interfere in
any way with the right of the Company or of any Subsidiary to terminate the
Optionee's employment or other relationship with the Company or the Subsidiary
at any time.

5.10     MODIFICATION AND AMENDMENT OF OPTIONS

         Subject to the terms and conditions and within the limitations of this
Plan, the Plan Administrator may modify or amend outstanding options granted
under this Plan.  Except as expressly provided under the terms of this Plan as
in effect at the time of granting the relevant option, the modification or
amendment of an outstanding option shall not, without the consent of the
Optionee, impair or diminish any of his or her options that have been granted,
or any of the obligations of the Company under such options.

5.11     BUYOUT PROVISIONS

         The Plan Administrator may at any time offer to buy out for a payment
in cash an option previously granted and held by an Optionee whose employment
or service relationship with the Company has been terminated, based on such
terms and conditions as the Plan Administrator shall establish and communicate
to the Optionee at the time such offer is made.

5.12     INCENTIVE STOCK OPTION LIMITATIONS

         To the extent required by Section 422 of the Code, incentive stock
options shall be subject to the following additional terms and conditions:

         5.12.1  DOLLAR LIMITATION

         To the extent the aggregate fair market value (determined as of the
grant date) of Common Stock with respect to which incentive stock options held
by an individual Optionee are exercisable for the first time during any
calendar year (under this Plan and all other stock option plans of the Company)
exceeds $100,000, such portion in excess of $100,000 shall be treated as a
nonqualified stock option.  In the event an Optionee holds two or more such
options that become exercisable for the first time in the same calendar year,
such limitation shall be applied on the basis of the order in which such
options are granted.





   
                                   PAGE 9                             
    
                                   
<PAGE>   10
         5.12.2  10% SHAREHOLDERS

         If an individual owns more than 10% of the total voting power of all
classes of the Company's stock, then the exercise price per share of an
incentive stock option shall not be less than 110% of the fair market value of
the Common Stock on the grant date and the option term shall not exceed five
years.  The determination of 10% ownership shall be made in accordance with
Section 422 of the Code.

         5.12.3  ELIGIBLE EMPLOYEES

         Individuals who are not employees of the Company or one of its
subsidiary corporations or parent corporations may not be granted incentive
stock options.  For purposes of this Section 5.12.3, "parent corporation" and
"subsidiary corporation" shall have the meanings attributed to those terms for
the purposes of Section 422 of the Code.

         5.12.4  TERM

         The term of an incentive stock option shall not exceed ten years.

         5.12.5  EXERCISABILITY

         To qualify for incentive stock option tax treatment, an option
designated as an incentive stock option must be exercised within three months
after termination of employment for reasons other than death, except that, in
the case of termination of employment due to total disability, such option must
be exercised within one year after such termination.  Employment shall not be
deemed to continue beyond the first 90 days of a leave of absence unless the
Optionee's reemployment rights are guaranteed by statute or contract.  For
purposes of this Section 5.12, "total disability" shall mean a mental or
physical impairment of the Optionee that is expected to result in death or that
has lasted or is expected to last for a continuous period of 12 months or more
and that causes the Optionee to be unable, in the opinion of the Company and
two independent physicians, to perform his or her duties for the Company and to
be engaged in any substantial gainful activity.  Total disability shall be
deemed to have occurred on the first day after the Company and the two
independent physicians have furnished their opinion of total disability to the
Plan Administrator.

         5.12.5  TAXATION OF INCENTIVE STOCK OPTIONS

         In order to obtain certain tax benefits afforded to incentive stock
options under Section 422 of the Code, the Optionee must hold the shares issued
upon the exercise of an incentive stock option for two years after the grant
date of the incentive stock option and one year from the date of exercise.  An
Optionee may be subject to the alternative minimum tax at the time of exercise
of an incentive stock option.  The Plan Administrator may require an Optionee
to give the Company prompt notice of any disposition of shares





   
                                   PAGE 10

acquired by the exercise of an incentive stock option prior to the expiration
of such holding periods.

                     SECTION 6.     STATUS AS SHAREHOLDERS

         Neither the Optionee nor any person or persons to whom the Optionee's
options and related privileges under this Plan may pass shall be or have any of
the rights and privileges of a shareholder of the Company except to the extent
that shares are acquired upon exercise of an option, and provided that nothing
in this Plan prohibits or prevents an Optionee from otherwise becoming a
shareholder of the Company.

                     SECTION 7.     CAPITALIZATION CHANGES

         The aggregate number and kind of securities subject to this Plan as
set forth in Section 3, the number and kind of securities subject to any
outstanding options granted under this Plan and the per share option exercise
price (without any change in the aggregate exercise price to be paid therefor)
shall all be proportionately adjusted for any increase or decrease in the
number of issued shares of Common Stock of the Company resulting from a
split-up or consolidation of shares or other similar capital adjustment, or the
payment of any stock dividend, or any other increase or decrease in the number
of shares of Common Stock of the Company without the Company's receipt (or
release) of consideration, proportionately equivalent to the added or
eliminated shares.  In the event of any adjustment in the number of such
securities, any fractional shares of Common Stock resulting from the adjustment
shall be disregarded.

                    SECTION 8.     AMENDMENT AND TERMINATION

         The Board may at any time suspend, amend or terminate this Plan;
provided, however, to the extent required for compliance with any applicable
law or regulation, shareholder approval will be required for any amendment that
will (a) increase the total number of shares as to which options may be granted
under this Plan, (b) modify the class of persons eligible to receive options,
or (c) otherwise require shareholder approval under any applicable law or
regulation.  No option may be granted after such termination, or during any
suspension of this Plan.  No incentive stock option may be granted more than
ten years after this Plan's adoption by the Board.  The amendment or
termination of this Plan shall not, without the consent of the Optionee, alter
or impair any options or obligations under any option previously granted under
this Plan.

                          SECTION 9.     GOVERNING LAW

         The provisions of this Plan shall be construed and interpreted
according to the laws of the State of Washington, without regard to its
conflicts of laws principles.

<PAGE>   12
                            SECTION 10.     VALIDITY

         In case any provision of this Plan is deemed illegal or invalid for
any reason, the illegal or invalid portion shall not affect the remaining parts
of this Plan, and this Plan shall be construed and enforced as if the illegal
or invalid provision had never been inserted.

                     SECTION 11.     TAXES AND WITHHOLDING

         The Company may withhold from any payment under this Plan or require
the Optionee to pay in cash any and all employment and income taxes that are
required to be withheld under applicable law.  Subject to this Plan and
applicable law, the Plan Administrator may, in its sole discretion, permit the
Optionee to satisfy withholding obligations, in whole or in part, by paying
cash, by electing to have the Company withhold shares of Common Stock or by
transferring shares of Common Stock to the Company, in such amounts as are
equivalent to the fair market value of the withholding obligation.  The Company
shall have the right to withhold from any shares of Common Stock issuable
pursuant to an option or from any cash amounts otherwise due or to become due
from the Company to the Optionee an amount equal to such taxes.  The Company
may also deduct from any option any other amounts due from the Optionee to the
Company or a Subsidiary.

         SECTION 12.     FIRST REFUSAL AND PUT RIGHTS; MARKET STAND-OFF

12.1     FIRST REFUSAL RIGHTS

         Until the date on which the initial registration of the Common Stock
under Section 12(b) or 12(g) of the Exchange Act first becomes effective, the
Company shall have the right of first refusal with respect to any proposed sale
or other disposition by the holder of any shares of Common Stock issued
pursuant to an option granted under this Plan.  Such right of first refusal
shall be exercisable in accordance with the terms and conditions established by
the Plan Administrator and set forth in the Stock Purchase Agreement evidencing
such right.

12.2     PUT RIGHTS

         Until the date on which the initial registration of the Common Stock
under Section 12(b) or 12(g) of the Exchange Act first becomes effective, the
shares of Common Stock issued pursuant to the exercise of an option shall be
entitled to certain "Put Rights" by the Optionee to compel the purchase of such
shares (the "Purchased Shares") by the Company or an affiliate pursuant to the
terms and conditions established by the Plan Administrator and set forth in the
Stock Purchase Agreement.  Such Put Rights may be exercised, except as provided
in the Stock Purchase Agreement with respect to the sale of a portion of the
Purchased Shares to the Company or an affiliate to




   
                                   PAGE 12                            
    
                                   
<PAGE>   13
satisfy the tax withholding obligations relating to the exercise of the Put
Right, only after the Purchased Shares have been held for at least six months
and only during a Semi-Annual Exercise Period.

12.3     MARKET STAND-OFF

         In connection with any underwritten public offering by the Company of
its equity securities pursuant to an effective registration statement filed
under the Securities Act of 1933, as amended (the "Securities Act"), including
the Company's initial public offering, a person shall not sell, or make any
short sale of, loan, hypothecate, pledge, grant any option for the purchase of,
or otherwise dispose or transfer for value or otherwise agree to engage in any
of the foregoing transactions with respect to, any shares issued pursuant to an
option granted under this Plan without the prior written consent of the Company
or its underwriters.  Such limitations shall be subject to the terms and
conditions established by the Plan Administrator and set forth in the Stock
Purchase Agreement.

                          SECTION 13.     REGISTRATION

         The Company shall be under no obligation to any Optionee to register
for offering or resale or to qualify for exemption under the Securities Act, or
to register or qualify under state securities laws, any shares of Common Stock,
security or interest in a security paid or issued under, or created by, this
Plan, or to continue in effect any such registrations or qualifications if
made.  The Company may issue certificates for shares with such legends and
subject to such restrictions on transfer and stop-transfer instructions as
counsel for the Company deems necessary or desirable for compliance by the
Company with federal and state securities laws.

         Inability of the Company to obtain, from any regulatory body having
jurisdiction, the authority deemed by the Company's counsel to be necessary for
the lawful issuance and sale of any shares hereunder or the unavailability of
an exemption from registration for the issuance and sale of any shares
hereunder shall relieve the Company of any liability in respect of the
nonissuance or sale of such shares as to which such requisite authority shall
not have been obtained.

         As a condition to the exercise of an option, the Company may require
the Optionee to represent and warrant at the time of any such exercise or
receipt that such shares are being purchased or received only for the
Optionee's own account and without any present intention to sell or distribute
such shares if, in the opinion of counsel for the Company, such a
representation is required by any relevant provision of the aforementioned
laws.  At the option of the Company, a stop-transfer order against any such
shares may be placed on the official stock books and records of the Company,
and a legend indicating that such shares may not be pledged, sold or otherwise
transferred, unless an opinion of counsel is provided (concurred in by counsel
for the Company) stating that such transfer is not in violation of any
applicable law or regulation, may be stamped on stock

certificates to ensure exemption from registration.  The Plan Administrator may
also require such other action or agreement by the Optionee as may from time to
time be necessary to comply with the federal and state securities laws.

                   SECTION 14.     EFFECTIVENESS OF THIS PLAN

         This Plan shall become effective upon adoption by the Board, so long
as it is approved by the Company's shareholders at any time within 12 months of
such adoption.

   
         Approved by the Board on June 23, 1997.
    

         Approved by the shareholders on               , 1997.

         (q)   "Separate Return Tax Liability," in the case of any Member, for
any Taxable Year of the Group means the liability of such Member hereunder for
federal income tax for such Taxable Year computed as if such Member had filed a
separate federal income tax return for such Taxable Year and for all prior

had filed a separate federal income tax return for all such taxable years or
periods, except that, in making such computation for any such taxable year,
such liability will be determined:

                  (i)      on the basis of the highest rate of corporate tax in

                           effect for such taxable year,

                  (ii)     on the assumption that the "exemption amount"

                           applicable to such Member for such taxable year is
                           zero,

                  (iii)    on the further assumption that the amount specified
                           in Section 59A(a)(2) of the Code which is applicable
                           to such Member for such taxable year is zero.

                           Return Tax Liability for such Taxable Year. The
                           amount of each such quarterly payment will be
                           determined by such Member, and such determination
                           will be made no later than ten days prior to the
                           date on which payment of the respective quarterly
                           estimate of the Group's Consolidated Tax Liability
                           for such Taxable Year must be made to the I.R.S. The
                           amount of each such quarterly payment determined by
                           such Member will equal the amount which such Member
                           would be required under Section 6655(d) of the Code
                           (or under any successor Section of the Code) to pay
                           to the I.R.S. for such quarter were such Member to

                           accordance with the provisions of such Section.

                  (ii)     If the actual Separate Return Tax Liability of any
                           such Member for such Taxable Year exceeds the total
                           estimated payments, if any, which such Member made
                           pursuant to Section 2(a)(i) for such Taxable Year,
                           such Member will pay an amount equal to the
                           difference between its actual Separate Return Tax
                           Liability for such Taxable Year and the sum of the
                           estimated payments, if any, that such Member made
                           pursuant to Section 2(a)(i) for such Taxable Year.

                  (iii)    In the case of any Member, each of the quarterly
                           payments required to be made by such Member pursuant
                           to Section 2(a)(i) will be made in the manner
                           provided in Section 5(a) on or before the due date
                           for the payment of the respective quarterly estimate
                           of the Group's Consolidated Tax Liability for such
                           Taxable Year. Any amount required to be paid by such
                           Member for such Taxable Year pursuant to Section
                           2(a)(ii) will be paid by such Member in the manner
                           provided in Section 5(a), as follows: (A) on the
                           fourteenth day of the third month after the end of
                           such Taxable Year such Member will pay an amount
                           equal to such Member's best estimate, as determined
                           by such Member, of the amount, if any, that such
                           Member owes pursuant to Section 2(a)(ii) for such
                           Taxable Year, and (B) on the thirtieth day after
                           Completion for such Taxable Year an amount equal to
                           the difference, if any, between (x) the amount
                           determined for such Taxable Year as the amount
                           payable by such Member pursuant to Section 2(a)(ii)
                           for such Taxable Year and (y) the amount, if any,
                           paid by such Member for such Taxable Year pursuant
                           to clause

                           amount at the rate specified in Section 5(b) from
                           the date on which the payment referred to in clause
                           (A) above was made to such thirtieth day following
                           Completion.

         (b)   If for any Taxable Year of the Group, any Member of the Group
has a Loss Item which the Common Parent for such Taxable Year is unable, due to
limitations prescribed by the Code, to utilize in computing the Group's
Consolidated Tax Liability for such Taxable Year or any prior Taxable Year, and
if such Member in such circumstance is able to carry back such Loss Item to a
prior taxable year or taxable years of such Member and to obtain a refund in
federal income tax as a result of such carryback, such Member will have no
obligation to remit the amount of such refund to the Common Parent.

3.       PAYMENTS TO MEMBERS AND CREDITING OF MEMBERS' ACCOUNTS

         (a)   For each Taxable Year of the Group, the payments and crediting

                           Separate Return Tax Liability for such Taxable Year,
                           such Member will be paid an amount equal to the
                           difference between (A) the payments that such Member
                           made pursuant to Section 2 for such Taxable Year and
                           (B) the amount of its actual Separate Return Tax
                           Liability for such Taxable Year, together with
                           interest thereon on such amount at the rate
                           specified in Section 5(b) from the date on which
                           payment was made under Section 2 to the date of
                           repayment under this Section 3.

                  (ii)     If any Member for a Taxable Year has a Loss Item
                           that such Member on a separate return tax basis
                           would be entitled under the applicable provisions of
                           the Code to carry back to a prior taxable year or
                           taxable years, an account established for such
                           Member will be credited with an amount equal to the
                           refund in federal income tax that such Member would
                           have been entitled to claim and receive had such
                           Member filed a separate federal income tax return
                           for such prior taxable year or taxable years. A
                           Member will not be entitled to receive any credit
                           pursuant to this Section 3(a)(ii) with respect to a
                           Loss Item to the extent such Loss Item is eligible

<PAGE>   8


                           prior taxable year or taxable years for which such
                           Member either (A) actually filed a separate federal
                           income tax return or (B) was included in the
                           consolidated return of another Affiliated Group, and
                           as to which such Member accordingly is entitled to
                           file, or have filed on its behalf, a claim for a
                           refund of federal income tax previously paid.

         (b)   In the case of any Member, any payment that such Member may be

Year and (ii) 30 calendar days after Completion.

         (c)   Any amounts credited to a Member's account pursuant to Section
3(a)(ii) will bear interest at the rate specified from time to time pursuant to
Section 6621(a)(2). Any amount credited to a Member's account will be paid to
the Member as follows:

                  (i)      If, with respect to any Taxable Year for which a
                           Member has a positive balance in its account (taking
                           into account any credits to such account with
                           respect to such Taxable Year), the Common Parent
                           receives a refund from the I.R.S., the Common Parent
                           shall pay to such Member an amount (not in excess of
                           the positive balance in such Member's account) equal
                           to the product of (x) the refund received by the
                           Common Parent and (y) a fraction, whose numerator is
                           the positive balance in such Member's account and
                           the denominator of which is the aggregate positive
                           balance in the accounts of all Members that have
                           positive balances in their accounts. Any amount so
                           paid by the Common Parent to a Member shall reduce
                           the Member's account.

                  (ii)     Any remaining amount in a Member's account shall be
                           used only to reduce the amount of any payment due
                           from such Member pursuant to Section 2. Any amount
                           so used shall reduce the Member's account.

         (d)   Any Member that receives a payment or other benefit pursuant to
Section 3(c)(i) or Section 3(c)(ii) will repay such benefit in the event such
Member ceases (other than as a result of a transaction to which Section 381 of
the Code applies and in which the surviving or resulting corporation is also a
Member) to be a Member before the Common Parent has utilized in full the Loss
Item that generated the reduction in determining the Group's Consolidated
Taxable Income or Consolidated

                                      -6-

Tax Liability for any Taxable Year or Taxable Years of the Group. If, as of the
end of the last Taxable Year of the Group in which such Member is a Member, the
Common Parent will have partially utilized such Loss Item in determining the
Group's Consolidated Taxable Income or Consolidated Tax Liability for any
Taxable Year or Taxable Years of the Group, such Former Member will repay a
proportionate part of such benefit, determined by multiplying the amount of
such benefit by a fraction, the numerator of which will be equal to the amount
of such Loss Item which the Common Parent has not so utilized and the
denominator of which will be equal to the aggregate amount of such Loss Item.
For purposes of the two preceding sentences, the extent, if any, to which any
such Loss Item has been utilized by the Common Parent in determining the
Group's Consolidated Taxable Income or Consolidated Tax Liability for the
Taxable Year or Taxable Years of the Group referred to in such sentences will
be determined in accordance with the provisions of Section 1.1502-79 of the
Consolidated Return Regulations. Any payment due from a Former Member pursuant
to this Section 3(d) will be made in the manner provided in Section 5(a) by
such Former Member within 15 days of the date on which such Former Member
receives written notice of the amount payable by such Former Member pursuant to
this Section 3(d).

         (e)   If a Member receives a payment pursuant to Section 3(c)(i) and
the Common Parent subsequently is required to remit part or all of the refund,
plus interest, to the I.R.S., the Member shall pay to the Common Parent an
amount (not in excess of the payment previously received by the Member pursuant
to Section 3(c)(i), plus interest at the rate specified in Section 5(b)) equal
to the product of (x) the remittance by the Common Parent to the I.R.S. and (y)
a fraction, whose numerator is the payment the Member received under Section
3(c)(i) for such Taxable Year and the denominator is the aggregate payment
received by all Members pursuant to Section 3(c)(i) for such Taxable Year. Any
amount so remitted by the Member to the Common Parent shall increase the
Member's account.

4.       ADDITIONAL OBLIGATIONS OF MEMBERS

                  (i)      a Member generates for any Taxable Year a Loss Item

                  (ii)     such credits or deductions cannot be utilized by the
                           Common Parent for such Taxable Year in determining

                           2(b) or Section 3(a)(ii), to any prior taxable year
                           or taxable years; and

                  (iii)    such Member ceases, for any reason (other than as a

         (d)   If either Section 4(a), Section 4(b) or Section 4(c) is
applicable to a Member or a Former Member, such Member or Former Member will
pay in the manner provided in Section 4(f) an amount equal to the difference
between (i) the Separate Return Tax Liability of such Member for the Taxable
Year or Taxable Years involved computed without regard to the Loss Item,
credit, or deduction referred to in Section 4(a), Section 4(b) or Section 4(c),
respectively, minus the Separate Return Tax Liability of such Member for such
Taxable Year or Taxable Years and (ii) the amount, if any, of the total
reduction in Consolidated Tax Liability for the then current and all prior
Taxable Years of the Group attributable to the Common Parent's utilization on
behalf of the Group of such Loss Item, credit, or deduction in determining the
Group's Consolidated Taxable Income and Consolidated Tax Liability for such
Taxable Year or Taxable Years.

         (e)   Any payment due pursuant to Section 4(d) from a Member or Former
Member will, in any case in which a Member ceases to be a Member of the Group,
be made within 15 days of the date on which the Member or Former Member
receives written notice of the amount payable by it pursuant to Section 4(d),
or, in any case in which a loss or credit carryover or deduction expires unused
be made on or before the fifteenth day of the third month following the close
of the Taxable Year in which the loss or credit carryover or deduction referred
to in Section 4(d), expires unused. Any

                                      -9-

<PAGE>   12

payment due pursuant to this Section 4(e) from a Member or Former Member will
be made by such Member or Former Member in the manner provided in Section 5(a).

         (f)   If a Member at any time acquires the assets and properties of
another Member pursuant to a transaction to which Section 381 of the Code
applies, the acquiring Member will, from and after the date of such
acquisition, be responsible for all of the undertakings and obligations of such
other Member hereunder and will, from and after such date, be entitled to
receive any and all payments that such other Member would be entitled to
receive hereunder. Provided such other Member ceases to exist solely as a
result of such transaction, such event will not, except as expressly provided
herein, in any way result in any acceleration of the time at which any payments
hereunder are due to or from such other Member, and, except as expressly
provided herein to the contrary, all such payments will be made to or by the
acquiring Member at the same time or times that such payments would be payable
to or by such other Member had such other Member continued to exist as a Member
hereunder.

         (g)   Any repayment obligation of a Member triggered by a Member's
ceasing to be a Member under Section 3(d) or this Section 4 shall not apply in
the event that a Member ceases to be a Member by reason of a foreclosure or
other exercise of remedies by a lender (or collateral agent or trustee for any
such lender) with respect to a pledge of the stock of such Member.

         (h)   For purposes of this Section 4, the term "utilize" for any
taxable year includes to the extent that the Common Parent makes an election
for such taxable year under Section 1.1502-20(g) of the Consolidated Return
Regulations to reattribtue to itself any portion of a Loss Item, credit or
deduction attributable to the Member (whether or not such item actually reduces
the tax liability of the Group for that year (or any other year)).

5.       REMITTANCES BY AND TO MEMBERS

         (a)   Until such time, if ever, as the Common Parent notifies each
other Member of the Group in writing to the contrary, any and all payments that
each such other Member agrees to make hereunder will be made and remitted by
each such Member directly to Common Parent. The Common Parent will be
responsible for making all payments required to be made hereunder to Members.

         (b)   Any payment required to be made pursuant to Section 5(a) by a
Member or the Common Parent which is not made on or before the date on which
such payment is due under the terms of this Agreement will bear interest at the
rate specified from time to time pursuant to Section 6621(a)(2) of the Code,
and any Member to whom such payment is due will be entitled to receive interest
computed at 

                                     -10-

<PAGE>   13

such rate upon the late payment of any such amount which is required at any
time to be paid hereunder.

6.       SUBSEQUENT ADJUSTMENTS

         If any adjustment is made to any item of income, gain, loss,
deduction, expense or credit of any Member of the Group for a Taxable Year
ending after the Effective Date during which such Member is a Member of the
Group by reason of the filing of an amended Consolidated Return, a claim for
refund with respect to such Taxable Year or an audit with respect to such
Taxable Year by the I.R.S., the amounts, if any, due to or from such Member
under this Agreement will be redetermined by taking into account any such
adjustment. If, as a result of such redetermination, any amounts due to or from
a Member under this Agreement differ from the amounts previously paid, then
except as herein provided, payment of such difference will be made to such
Member or by such Member in the manner provided in Section 5(a) as follows: (a)
in the case of an adjustment resulting in a credit or refund of tax, within ten
calendar days of the date on which such refund or notice of such credit is
received by the Common Parent or such Member with respect to such adjustment,
or (b) in the case of an adjustment resulting in the assessment of a deficiency
in tax, within ten calendar days of the date on which such deficiency is paid.
Any amounts due under this Section 6 will include any interest attributable
thereto under Sections 6601 or 6611 of the Code and any penalties or additional
amounts which may be imposed. Any amount due pursuant to this Section 6 from a
Former Member will nevertheless be paid by such Former Member at the time
indicated above and in the manner provided in Section 5(a) unless the Common
Parent has agreed in writing prior to the date on which any such payment would
be due to release such Former Member from such obligation. In the event the
redetermination referred to in this Section results in a Former Member being
entitled to receive a payment pursuant to this Section, such Former Member will
not be entitled to receive any amount pursuant to this Section 6 unless the
Common Parent has agreed in writing prior to the date on which any such payment
would be due to permit such Former Member to receive such payment.

7.       CARRYBACKS FROM SEPARATE RETURN YEARS

         If, for any Taxable Year in the future of a Former Member, such Former
Member has a net operating loss, a net capital loss, or is entitled to credits
against tax which such Former Member, under applicable provisions of the Code
or the Consolidated Return Regulations, may carry back to a Taxable Year or
Taxable Years of the Group during which such Former Member was a Member of the
Group, the Common Parent will have no obligation to pay to such Former Member
the amount of any refund or credit of federal income tax that the Common Parent
may receive as a

                                     -11-

<PAGE>   14

result of the carryback by such Former Member of any such losses or credits;
provided, that the foregoing shall not apply in the event that a Member ceases
to be a Member of the Group by reason of a foreclosure or other exercise of
remedies by a lender (or collateral agent or trustee for any such lender) with
respect to a pledge of the stock of such Member.

8.       DETERMINATIONS AND COMPUTATIONS

         (a)   All determinations and computations required to be made 
hereunder, including without limitation all computations of (i) Consolidated
Taxable Income and Consolidated Tax Liability for each Taxable Year of the
Group and (ii) the Separate Return Tax Liability for each such Taxable Year of
each Member will be made by the independent public accountants regularly
employed by the Common Parent at the time that any such determination or
computation is required to be made. The results of any such determination or
computation so made by such independent public accountants will be binding and
conclusive upon the parties hereto for all purposes hereof.

         (b)   The purpose of this Agreement is to ascertain in a reasonable 
and equitable manner the income tax liability of each Member. If a fact pattern
arises in the administration of this Agreement which requires a calculation or
determination that is not dealt with in the specific provisions hereof, the
independent public accountants regularly employed by the Common Parent will be
responsible for performing such calculations or making such determinations. In
making any such calculation or determination, such independent public
accountants will attempt to follow as closely as possible the general concepts
set forth in this Agreement by analogizing to the specific provisions hereof.
The results of any such determination or computation so made by such
independent public accountants will be binding and conclusive upon each of the
parties hereto for all purposes hereof.

         (c)   For each Taxable Year of the Group, each Member of the Group 
will compute its Separate Return Tax Liability consistent with any elections
made by the Common Parent.

9.       PROCEDURAL MATTERS

         (a)   The Common Parent will be solely responsible for making any
estimated or final payments to the I.R.S. in satisfaction of the federal income
tax liability (including additions to tax, penalties, and interest) of the
Group and each of its Members for each Taxable Year of the Group.

         (b)   The Common Parent will prepare and file, or will cause the
independent public accountants that it regularly employs on behalf of the Group
to prepare and on

                                     -12-

<PAGE>   15


its behalf file, the Consolidated Return and any other returns, documents or
statements required to be filed with the I.R.S. which pertain to the
determination of the Consolidated Tax Liability of the Group for each Taxable
Year of the Group. In its sole and absolute discretion, the Common Parent will
have the right with respect to any Consolidated Return that it or such
independent public accountants has filed or will file: (i) to determine (A) the
manner in which such Consolidated Return, as well as any other documents or
statements incidental or related thereto, will be prepared and filed, including
without limitation the manner in which any item of income, gain, loss,
deduction, expense, or credit of any Member will be reported therein or
thereon, (B) whether any extensions with respect to any such Consolidated
Return will be requested, and (C) the elections that will be made in any such
Consolidated Return by any Member; (ii) to contest, compromise, or settle any
adjustment or deficiency proposed, asserted, or assessed as a result of any
audit of such Consolidated Return by the I.R.S.; (iii) to file an amended
Consolidated Return and to prosecute, compromise or settle any claim for refund
set forth therein; and (iv) to determine whether any refunds to which the Group
may be entitled will be paid by way of cash refund or credited against the
Consolidated Tax Liability of the Group for any Taxable Year or Taxable Years
of the Group. Each Member hereby irrevocably appoints the Common Parent as its
agent and attorney-in-fact to take any action (including the execution of
documents) as the Common Parent may deem appropriate to effect the foregoing.

         (c)   The Common Parent will prepare, or will cause the independent
public accountants that it regularly employs on behalf of the Group to prepare,
on behalf of each Member any and all Corporation Applications for Tentative
Refund (Form 1139), Amended U.S. Corporation Income Tax Returns (Form 112OX),
or Claims for Refund (Form 843) that such Member is eligible to file with the
I.R.S. with respect to any prior taxable year or taxable years of such Member.
The Common Parent will deliver, or will cause such public accountants to
deliver, to such Member any such completed Form as soon as practicable after
such Form has been completed, and such Member will, within ten days of
receiving such Form, sign such Form and file the same with the appropriate
office of the I.R.S. If any such Member fails to file any such Form with the
I.R.S. within such 10-day period, such Member will, as hereinafter provided,
pay an amount equal to the amount of interest that such Member would have
received from the I.R.S. had such Member filed such Form with the I.R.S. within
such 10-day period but which such Member fails to receive as a consequence of
its delinquency in the filing of such Form; provided, however, that if any such
delay in the filing of such Form causes the claim for refund of tax made by
such Form to be disallowed by the I.R.S. on the ground that the period of
limitations prescribed in Section 6511 of the Code for claiming such refund has
expired as of the date such Form actually was filed with the I.R.S., such
Member will, in lieu of making the above-described payment, pay as hereinafter
provided an amount equal to the sum of


                                     -13-

<PAGE>   16

(i) the amount of the refund of tax claimed on such Form, plus (ii) an amount
equal to the amount of interest that such Member would have received from the
I.R.S. had the claim for refund of tax evidenced by such Form been allowed by
the I.R.S. on the day before the date on which the period of limitations for
claiming such refund expired. Any payment due pursuant to this Section 9(c)
from a Member will be made in the manner provided in Section 5(a) within ten
days of the date on which such Member receives written notice from the Common
Parent that such Member is required to make a payment pursuant to this Section
9(c). Any amount payable pursuant to this Section 9(c) by a Former Member
which, on the date on which any Form referred to in this Section 9(c) was
delivered to such Former Member was a Member of the Group, will be paid by such
Former Member at the time and in the manner indicated above unless the Common
Parent has agreed in writing prior to the date on which such payment would be
due to release such Former Member from the obligations imposed on it under this
Section 9(c).

         (d)   Each Member which at any time makes a determination pursuant to
Section 2(a)(i) of its estimated Separate Return Tax Liability for any Taxable
Year will, immediately after making any such determination, send a copy of such
determination to the independent public accountants that the Common Parent
regularly employs on behalf of the Group.

10.      UTILIZATION OF MEMBER TAX ATTRIBUTES, ETC. IN DETERMINING CONSOLIDATED
         TAX LIABILITY

         In determining the Consolidated Taxable Income and Consolidated Tax
Liability and in preparing the Consolidated Return of the Group for any Taxable
Year of the Group, the Common Parent will be entitled, and hereby is
authorized, to utilize on behalf of the Group all of the tax attributes and
other items of income, gain, loss, deduction, expense, credit, etc. of each
such Member arising in such Taxable Year or which arose in another Taxable Year
or Taxable Years (or other period or periods) and which properly may be carried
back or carried forward to such Taxable Year. Except as expressly provided for
herein, no Member of the Group will in any manner be entitled to receive any
form of compensation by reason of the Common Parent's utilization of such
Member's tax attributes and items of income, gain, loss, deduction, expense,
credit, etc. on behalf of the Group in determining for any Taxable Year or
Taxable Years the Group's Consolidated Taxable Income and Consolidated Tax
Liability for such Taxable Year or Taxable Years.

11.      ADDITIONS TO GROUP

         If any Member of the Group will at any time organize or acquire any
other corporation, provided that such corporation becomes a Member of the
Group, the 

                                     -14-

<PAGE>   17


Member of the Group that organizes such corporation or consummates such
acquisition will obtain the agreement of such newly organized or acquired
corporation to join in this Agreement and to be bound by all of the terms
hereof and will cause such corporation to execute a written consent,
substantially in the form of the consent attached hereto as Attachment A,
evidencing its agreement to join in this Agreement and to be bound by the terms
hereof. Each of the parties hereto, and each corporation that subsequently
becomes a party to this Agreement, consents to such corporation joining in this
Agreement.

12.      STATE TAXES

         (a)   Each Member agrees that upon the request of the Common Parent it
will join with such other Members as are designated by the Common Parent in any
consolidated, combined, or unitary state or local income or franchise tax
return or report for any taxable year.

         (b)   For any taxable year for which such a return is filed that
includes a Member, this Agreement will be applied to all matters relating to
the taxes relating to such return in a manner similar to and consistent with
its application to federal income tax matters.

13.      EFFECTIVE DATE

         This Agreement will be effective for all Taxable Years of the Group
ending after the Effective Date.

14.      AMENDMENT AND WAIVER

         This Agreement may be amended, modified, waived, discharged, or
terminated only by an instrument in writing signed by each of the parties
hereto.

15.      SUCCESSORS AND ASSIGNS

         This Agreement will be binding upon and inure to the benefit of the
parties hereto and their respective successors and permitted assigns, but will
not be assignable or delegable by any party without the prior written consent
of each other party. In the absence of such prior written consent, any
purported assignment or delegation of any right or obligation hereunder will be
null and void.

16.      RIGHTS OF THE PARTIES

         Except as provided in Section 15, nothing expressed or implied in this
Agreement is intended or will be construed to confer upon or give any person or
entity 

                                     -15-

<PAGE>   18


other than the parties hereto any rights or remedies under or by reason of this
Agreement or any transaction contemplated hereby.

17.      EXPENSES

Agreement and the transactions contemplated hereby.

agreement among the parties hereto with respect to the subject matter hereof,
and there are no agreements among the parties hereto with respect thereto
except as expressly set forth herein.

20.      SEVERABILITY

          In case any provision contained in this Agreement is invalid,
illegal, or unenforceable, the validity, legality, and enforceability of the
remaining provisions will not in any way be affected or impaired thereby.

21.      GOVERNING LAW

         This Agreement will be governed by and construed in accordance with
the laws of the State of Delaware, without giving effect to the principles of
conflict of laws thereof.

22.      COUNTERPARTS

                                    OVERHEAD
                               SERVICES AGREEMENT



         This is the Overhead Services Agreement (the "Agreement") dated March
3, 1997, between Nextel Communications, Inc., a Delaware corporation (the
"Parent"), and McCaw International, Ltd., a Washington corporation (the
"Subsidiary").

         In consideration of the mutual covenants and agreements of the
parties, the parties agree as follows:

1.       SERVICES TO BE PROVIDED.

         1.1     Parent shall provide the services set forth on Exhibit A to
Subsidiary.  With the written consent of Parent, Subsidiary may elect to
discontinue a service or services provided by Parent and/or obtain any service
listed on Exhibit A from an independent third party.

         1.2     The fee for any service provided by Parent hereunder for any
fiscal year shall be the actual cost incurred by Parent for the service
provided to Subsidiary.

         1.3     Parent undertakes to provide the services required hereunder
with the same degree of care and diligence, and using the same procedures and
policies, that it uses in providing services for its own operation and for its
other subsidiaries.

2.       PAYMENT OF COMPENSATION.

         2.1     Parent shall apportion the aggregate cost incurred by Parent
to provide each service listed on Exhibit A among its subsidiaries (including
the Subsidiary) on the basis that Parent determines in good faith, from time to
time, represents the relative portion of the services provided by Parent and
used by each such subsidiary (including the Subsidiary) for the relevant
period.  Subsidiary shall have the right to review Parent's determination and
to discuss with Parent adjustments that Subsidiary considers appropriate in
light of the services provided to Subsidiary.  Parent's good faith and
determination after such consultation shall be final and binding on such
Subsidiary.

         2.2     Nextel will charge such Subsidiary monthly and amounts due
shall be paid in not less than 45 days.

3.       TERM OF AGREEMENT AND TERMINATION.

         3.1     TERM.  This Agreement shall be effective as of its date and
shall remain effective until March 3, 2007.


                                      1
<PAGE>   2
         3.2     FORCE MAJEURE.  No party shall be liable in any manner for
failure or delay in performance of all or any part of this Agreement, directly
or indirectly, owing to acts or God, governmental orders or restrictions,
strikes or other labor disturbances, riots, embargoes, revolutions, wars,
sabotage, fire, floods, or any other cause or circumstance or a combination
thereof beyond the control of the parties.  The party suffering any such delay
or failure shall give prompt notice to the other party responsible to perform
and shall exert best efforts to remove the causes or circumstances of
non-performance as promptly as practicable.

         3.3     ACCRUED PAYMENT.  Termination of this Agreement shall not
affect the right of Parent to any sums accrued prior to the date of
termination.

4.       GENERAL PROVISIONS.

         4.1     OTHER SERVICES.  Nothing in this Agreement shall restrict the
Parent from undertaking to provide additional services to Subsidiary not
described in this Agreement on terms and conditions satisfactory to the Parent
and Subsidiary.

         4.2     CONFLICTS OF INTEREST.  Subsidiary acknowledges that the legal
counsel employed by Parent as part-time or full-time employees will provide
legal services to Parent as well as to a variety of subsidiaries of Parent and
potentially to other entities in which Parent holds an ownership interest.
Subsidiary agrees that such legal counsel may represent Subsidiary as well as
Parent or any other such subsidiary or other entity.  In situations in which
the interests of Subsidiary and Parent are adverse to each other, Subsidiary
agrees that it shall make no attempt to disqualify or prohibit such legal
counsel from representing Subsidiary solely because of such legal counsel's
prior or present representation of Parent.

         4.3     COUNTERPARTS.  This Agreement may be executed by the parties
in separate counterparts, each of which when so executed and delivered shall be
an original, but all counterparts shall together constitute but one and the
same document.

         4.4     GOVERNING LAW.  This Agreement shall in all respects be
governed by, and construed in accordance with, the internal laws of the State
of Delaware, applicable to Agreements made and to be performed within that
state, without regard to the conflicts of laws and principals of that state.

         4.5     ASSIGNMENT.  Subsidiary may not assign its rights or
obligations under this Agreement without the prior written consent of Parent.

         IN WITNESS WHEREOF, the parties have caused this Agreement to be
executed by their duly authorized representatives.

                  Re:  Motorola International Financing

Dear Sirs:

                  We refer to that certain Memorandum of Understanding entered
into on or about November 12, 1996 (the "Memorandum of Understanding")
captioned "MOTOROLA VENDOR FINANCING TEMPLATE", by and between McCaw
International, Ltd. ("MIL") and Motorola, Inc. ("Motorola"), acknowledged and
agreed to by Nextel Communications, Inc. ("Nextel"). Such Memorandum of
Understanding, together with all attachments thereto and any and all term
sheets or definitive agreements entered into to establish or reflect the terms
and conditions of any credit available or indebtedness outstanding thereunder
(being referred to collectively as the "Motorola International Financing
Documents"). On the date hereof, the existing Motorola International Financing
Documents contemplate that the worldwide amount of vendor equipment financing
provided by Motorola (i) to Nextel and certain of its subsidiaries that are
"Restricted Companies" (Nextel and such subsidiaries collectively, the "U.S.
Borrowers") under the U.S. Vendor Agreement (as defined in the Memorandum of
Understanding) and (ii) to MIL and certain of its designated affiliates (MIL
and such affiliates collectively, the "MIL Group") under the Motorola
International Financing Documents will be subject to a maximum aggregate limit
of $400 million.

                  We hereby state our mutual understanding and agreement as
follows:

         (1)      Nextel commits that none of the U.S. Borrowers will borrow
                  amounts under the U.S. Vendor Facility if, at the time of and
                  giving effect to such borrowing and all other amounts then
                  outstanding under the U.S. Vendor Facility, either (a)
                  amounts borrowed from Motorola thereunder would exceed $400
                  million or (b) as a result of such borrowing, the total of
                  all amounts outstanding or then


<PAGE>   6

                  remaining available to the MIL Group under the Motorola
                  International Financing Documents would be less than $95
                  million; and

         (2)      MIL commits that no member of the MIL Group will, without the
                  prior written consent of the Chief Financial Officer of
                  Nextel, (a) borrow amounts under the Motorola International
                  Financing Documents if, at the time of and giving effect to
                  such borrowing and all other amounts then outstanding
                  thereunder and all other amounts borrowed from Motorola and
                  then outstanding under the U.S. Vendor Facility, the total of
                  all amounts so borrowed from Motorola by members of the MIL
                  Group and by the U.S. Borrowers, as appropriate, would exceed
                  $400 million or (b) change, or consent to any change, in the
                  $400 million aggregate worldwide outstandings limit set forth
                  in the Memorandum of Understanding.

                  MIL and Nextel each understand and acknowledge that
borrowings and access to funds under the U.S. Vendor Facility and under the
Motorola International Financing Documents will be subject to the applicable
terms and conditions set forth in those documents, and MIL specifically
understands and agrees that, except as expressly set forth above, Nextel has no
obligation, express or implied, to act or refrain from acting to assure
satisfaction of any of the conditions to borrowing under any of the Motorola
International Financing Documents or otherwise to assure that any member of the
MIL Group will have or retain access any amount of financing thereunder.

                      RIGHT OF FIRST OPPORTUNITY AGREEMENT


                  RIGHT OF FIRST OPPORTUNITY AGREEMENT, dated as of March 6,
1997 (the "Agreement"), between NEXTEL COMMUNICATIONS, INC., a Delaware
corporation ("Nextel") and MCCAW INTERNATIONAL, LTD., a Washington corporation
and wholly owned subsidiary of Nextel ("MIL").


                             W I T N E S S E T H :


                  WHEREAS, MIL is offering 951,463 Units, each Unit consisting
of one 13% Senior Discount Note due 2007 of MIL (the "Notes") and one warrant
(the "Warrants") to purchase .10616 shares of common stock, no par value, of
MIL at an exercise price of $36.45 per share, subject to adjustment (the
"Offering"); and

                  WHEREAS, to facilitate the Offering, the parties hereto
desire to provide for certain matters concerning Nextel's and MIL's respective
involvement in the international wireless telecommunications industry.

                  NOW, THEREFORE, in consideration of the foregoing and other
good and valuable consideration, receipt of which is acknowledged, the parties,
intending to be legally bound hereby, hereto agree as follows:

                  SECTION 1. First Opportunity Procedures. Nextel hereby agrees
that until the earliest to occur of (i) April 15, 2007 and (ii) the date on
which a Change of Control (as such term is defined in the Indenture pursuant to
which the Notes were issued; the "Indenture") occurs, neither Nextel nor any
Affiliate that is controlled by Nextel (other than MIL or any Restricted Group
Member (as such term is defined in the Indenture; collectively, the "MIL
Group")) shall be a party to any Future Wireless Opportunity (as such term is
defined below) except in compliance with the procedures set forth in this
Section. A "Future Wireless Opportunity" shall mean any transaction in which
Nextel or any Affiliate that is controlled by Nextel would hold any equity
securities or similar instrument representing an ownership interest ("Equity
Interest") in another Wireless Entity (as such term is defined below), or would
direct or otherwise participate in the management of another Wireless Entity;
provided that the term "Future


<PAGE>   2


Wireless Opportunity" shall not mean or include any of the following: (i)
holding any Equity Interest in any member of the MIL Group or directing or
participating in the management of any member of the MIL Group, (ii) holding
any securities in or issued by any Wireless Entity which are not convertible
into or exercisable or exchangeable for any Equity Interest in a Wireless
Entity, (iii) holding any Equity Interest (or securities that are convertible
into or exercisable or exchangeable for any Equity Interest) in a Wireless
Entity that represents, on a fully-diluted basis, five percent (5%) or less of
the total fully-diluted Equity Interests in such Wireless Entity, (iv)
continuing to hold any investment in a wireless communications service business
with operations outside the United States of America (including its
territories, possessions and protectorates) that was made by Nextel prior to
the date hereof and was not contributed to MIL prior to the date on which the
Offering is consummated, or continuing to exercise rights to direct or
participate in the management of any such business or (v) any commercial
relationship with any Wireless Entity (including, without limitation, channel
or frequency sharing, roaming, the purchase, sale or exchange of goods and/or
services, licensing of intellectual property or other intangible rights or
similar business related arrangement) that does not involve directing or
participating in the management of such Wireless Entity. A "Wireless Entity"
shall mean any corporation, partnership, trust, association or other form of
business organization ("Entity") whose principal business activity involves the
direct or indirect ownership or operation of two-way terrestrial-based mobile
wireless communications systems anywhere in the world other than (A) the United
States of America (including its territories, possessions and protectorates)
and (B) so long as Nextel has any direct or indirect Equity Interest (other
than those held by or through a member of the MIL Group) in Clearnet
Communications, Inc. (including any successor to such entity or to all of the
specialized mobile radio communications business activities conducted by such
entity or its subsidiaries; "Clearnet"), in any of the provinces and
territories that, on the date of this Agreement, collectively constitute Canada
(the areas described in the foregoing clauses (A) and (B), the "Excluded
Areas"), but shall not mean or include any such Entity in which Nextel or its
controlled Affiliates (other than any member of the MIL Group) first acquired
an Equity Interest or first became entitled to direct or participate in the
management of following compliance with the procedures set forth in the next
paragraph of this Section. Except at Nextel's specific

                                       2

<PAGE>   3

request or with Nextel's prior written consent, no member of the MIL Group
shall hold, acquire or direct or otherwise participate in the management of any
wireless communications service business (other than Clearnet) having any
operations in the Excluded Areas.

                  If Nextel or any of its controlled Affiliates becomes aware
of any Future Wireless Opportunity, it shall promptly notify the Chief
Executive Officer and the Board of Directors of MIL of such Future Wireless
Opportunity and, to the extent known, of the terms, conditions and
circumstances applicable to such Future Wireless Opportunity (such notice the
"Initial Notice"). If either (i) the Board of Directors of MIL (or of the
appropriate member of the MIL Group) thereafter notify Nextel that such member
of the MIL Group is not able or elects not to pursue such Future Wireless
Opportunity or (ii) the appropriate member of the MIL Group has not notified
Nextel, within sixty (60) days after the date of the Initial Notice, that such
member intends to pursue the Future Wireless Opportunity (provided that if such
Future Wireless Opportunity involves any financial commitment to be made by an
MIL Group member, Nextel will not be deemed to have been notified that an MIL
Group member intends to pursue the Future Wireless Opportunity unless the
notification of such intent ("Notice of Intent") is either preceded or
accompanied by (A) a statement, in reasonable detail, of the sources of
financing reasonably available to such MIL Group member that will be used to
satisfy such financial commitment and that such financing is permitted under
the Indenture and the other loan documents, if any, to which the applicable MIL
Group members are parties or by which they are bound (a "Financing Statement")
or (B) a good faith written undertaking to identify the source and nature of
such financing in a writing to be delivered to Nextel within 30 days after the
date on which the Notice of Intent is delivered ("Proposed Financing Notice"),
and to deliver a Financing Statement consistent with the Proposed Financing
Notice within 60 days after the Notice of Intent is delivered; provided that a
failure to timely deliver a Proposed Financing Notice or the related Financing
Statement will be treated as an election by the MIL Group not to pursue such
Future Wireless Opportunity) or (iii) thereafter ceases to pursue such Future
Wireless Opportunity diligently and in good faith or fails to consummate such
Future Wireless Opportunity within nine months of the date of the Initial
Notice (extended as may be reasonably required to obtain any necessary
governmental approval or clearances) then, and in any such event, Nextel or any
of its controlled

                                       3

<PAGE>   4

Affiliates may pursue for itself and consummate, without further obligation,
condition or restriction under this Section, such Future Wireless Opportunity
on substantially the same terms and conditions as were set forth in the Initial
Notice (or, if applicable and at Nextel's election, on terms and conditions in
the aggregate no more favorable to Nextel or its appropriate controlled
Affiliate than those (if any) advanced by any member of the MIL Group that
previously elected to pursue such Future Wireless Opportunity as acceptable to
such member). Nothing in this Section shall obligate Nextel or any of its
controlled Affiliates to provide any financing or any other assistance to any
member of the MIL Group in connection with such member's consideration and/or
pursuit of any such Future Wireless Opportunity.

                  For purposes of this Section 1:

                  "Affiliate" as applied to any Person, means any other Person
         directly or indirectly controlling, controlled by, or under direct or
         indirect common control with, such Person. For purposes of this
         definition, "control" (including, with correlative meanings, the terms
         "controlling," "controlled by" and "under common control with"), as
         applied to any Person, means the possession, directly or indirectly,
         of the power to direct or cause the direction of the management and
         policies of such Person, whether through the ownership of voting
         securities, by contract or otherwise.

                  SECTION 2. Third Party Beneficiaries. The holders of Notes
and the Warrants shall be third party beneficiaries of the agreements made
hereby between Nextel, on the one hand, and MIL on the other hand, and each
holder of Notes and Warrants shall have the right to enforce such agreements
directly to the extent it deems such enforcement necessary or advisable to
protect its rights or the rights of holders of the Notes and the Warrants
thereunder, provided, that such rights may only be exercised through the
Trustee under the Indenture or the Warrant Agent under the Warrant Agreement,
or another reasonably acceptable representative authorized to act by holders of
a majority of the outstanding Notes or Warrants, as the case may be, with the
power to bind all holders of Notes and Warrants.

                  SECTION 3. Severability. In the event that any one or more of
the provisions contained herein, or the

                                       4

<PAGE>   5

application thereof in any circumstances, is held invalid, illegal or
unenforceable in any respect for any reason, the validity, legality and
enforceability of any such provision in every other respect and of the
remaining provisions contained herein shall not be in any way impaired thereby,
it being intended that all of the rights and privileges of the parties hereto
shall be enforceable to the fullest extent permitted by law.

                  SECTION 4. Specific Performance. Without limiting the rights
of each party hereto to pursue any and all other legal and equitable rights
available to such party for the other parties' failure to perform their
obligations under this Agreement, the parties hereto acknowledge and agree that
the remedy at law for any failure to perform their obligations hereunder would
be inadequate and that each of them, respectively, shall be entitled to
specific performance, injunctive relief or other equitable remedies in the
event of any such failure.

                  SECTION 5. Amendments. Subject to the next succeeding
sentence this Agreement may be amended at any time by MIL and Nextel. MIL and
Nextel agree, for the benefit of the holders of Notes and Warrants, not to
amend this Agreement in any respect material and adverse to the holders of
Notes or Warrants and to give written notice of any proposed amendment to the
Trustee and the Warrant Agent at least 30 days prior to the effectiveness
thereof.

                  SECTION 6.  Assignment.  Neither this Agreement nor any of the
rights, interests or obligations of any party hereto may be assigned by such
party without the prior written consent of the other party.
 

                  SECTION 7.  Counterparts.  This Agreement may be executed in
one or more counterparts, all of which together shall constitute a single
agreement, and all of which shall constitute an original for all purposes.

BY AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW

                 Re:  Motorola International Financing

Dear Sirs:

                 We refer to that certain Memorandum of Understanding entered 
into on or about November 12, 1996 (the "Memorandum of Understanding")  
captioned "MOTOROLA VENDOR FINANCING TEMPLATE", by and between McCaw
International, Ltd. ("MIL") and Motorola, Inc. ("Motorola"), acknowledged and
agreed to by Nextel Communications, Inc. ("Nextel").  Such Memorandum of
Understanding, together with all attachments thereto and any and all term
sheets or definitive agreements entered into to establish or reflect the terms
and conditions of any credit available or indebtedness outstanding thereunder
(being referred to collectively as the "Motorola International Financing
Documents").  On the date hereof, the existing Motorola International Financing
Documents contemplate that the worldwide amount of vendor equipment financing
provided by Motorola (i) to Nextel and certain of its subsidiaries that are
"Restricted Companies" (Nextel and such subsidiaries collectively, the "U.S.
Borrowers") under the U.S. Vendor Agreement (as defined in the Memorandum of
Understanding) and (ii) to MIL and certain of its designated affiliates (MIL
and such affiliates collectively, the "MIL Group") under the Motorola
International Financing Documents will be subject to a maximum aggregate limit
of $400 million.

                 We hereby state our mutual understanding and agreement as 
follows:
<PAGE>   2
         (1)     Nextel commits that none of the U.S. Borrowers will borrow
                 amounts under the U.S. Vendor Facility if, at the time of and
                 giving effect to such borrowing and all other amounts then
                 outstanding under the U.S. Vendor Facility, either (a) amounts
                 borrowed from Motorola thereunder would exceed $400 million or
                 (b) as a result of such borrowing, the total of all amounts
                 outstanding or then remaining available to the MIL Group under
                 the Motorola International Financing Documents would be less
                 than $95 million; and

         (2)     MIL commits that no member of the MIL Group will, without the
                 prior written consent of the Chief Financial Officer of
                 Nextel, (a) borrow amounts under the Motorola International
                 Financing Documents if, at the time of and giving effect to
                 such borrowing and all other amounts then outstanding
                 thereunder and all other amounts borrowed from Motorola and
                 then outstanding under the U.S. Vendor Facility, the total of
                 all amounts so borrowed from Motorola by members of the MIL
                 Group and by the U.S. Borrowers, as appropriate, would exceed
                 $400 million or (b) change, or consent to any change, in the
                 $400 million aggregate worldwide outstandings limit set forth
                 in the Memorandum of Understanding.

                 MIL and Nextel each understand and acknowledge that borrowings
and access to funds under the U.S. Vendor Facility and under the Motorola
International Financing Documents will be subject to the applicable terms and
conditions set forth in those documents, and MIL specifically understands and
agrees that, except as expressly set forth above, Nextel has no obligation,
express or implied, to act or refrain from acting to assure satisfaction of any
of the conditions to borrowing under any of  the Motorola International
Financing Documents or otherwise to assure that any member of the MIL Group
will have or retain access any amount of financing thereunder.
