     On July 28, 1995, NEXTEL Communications, Inc., a corporation organized
under the laws of the State of Delaware in 1987 ("Old Nextel"), was merged with
ESMR, Inc. ("ESMR"), until then a wholly owned subsidiary of Motorola, Inc.
("Motorola"). ESMR was the surviving corporation in the merger (the "Motorola
Transaction") and succeeded to Old Nextel's assets and liabilities. ESMR changed
its name to Nextel Communications, Inc., effective upon consummation of the
Motorola Transaction. References herein to Nextel for periods prior to July 28,
1995 refer to Old Nextel as the predecessor to the business and operations of
Nextel. Unless the context requires otherwise, references to Nextel are intended
to include Nextel Communications, Inc. and its consolidated subsidiaries.
 
     Information contained herein gives effect to the acquisition of
approximately 1,220,000 shares of Common Stock by Digital Radio L.L.C. (the
"McCaw Investor") on April 5, 1995, an additional acquisition of 8,163,265
shares of Nextel's Class A Convertible Redeemable Preferred Stock, par value
$.01 per share (the "Class A Preferred Stock"), and 82 shares of Nextel's Class
B Convertible Preferred Stock, par value $.01 per share (the "Class B Preferred
Stock"), by the McCaw Investor and the consummation of related transactions on
July 28, 1995 (the "McCaw Transaction"), the merger of OneComm Corporation
("OneComm") with and into Nextel on July 28, 1995 (the "OneComm Transaction"),
the consummation of the Motorola Transaction on July 28, 1995, the merger of a
subsidiary of Nextel with American Mobile Systems Incorporated ("AMS") on July
31, 1995 (the "AMS Transaction") and the merger of Dial Page with and into
Nextel on January 30, 1996 (the "Dial Page Transaction").
 
                                  THE COMPANY
 
OVERVIEW
 
     Nextel's business consists principally of providing a wide array of digital
and analog wireless communications services to its customers in the United
States, in each case utilizing frequencies licensed to its subsidiaries by the
Federal Communications Commission ("FCC"). Nextel provides a differentiated
package of integrated digital wireless communications services under the Nextel
brand name to customers of the various networks constructed and operated by
Nextel's subsidiaries in and around major metropolitan population centers
throughout the country. Collectively, Nextel's operations constitute one of the
largest integrated wireless communications networks utilizing a single digital
transmission technology currently offering commercial service in the United
States. Through its digital and analog wireless communications networks, Nextel
is the leading provider of specialized mobile radio ("SMR") wireless
communications services in nearly all 48 states in the continental United States
and in Hawaii. Nextel has significant SMR spectrum holdings in and around every
major business and population center in the country, including all of the top 50
metropolitan market areas in the United States.
 
     Nextel's operating revenues primarily arise from its digital and analog
wireless communications businesses in the United States, particularly the mobile
telephone service and two-way radio service and, to a lesser extent, from sales
and maintenance of related equipment. Nextel's business plans and efforts are to
a large extent directed toward replacing the traditional analog SMR systems that
it currently operates with advanced mobile communications systems employing
digital technology with a multi-site configuration permitting frequency reuse
("Digital Mobile networks"). A customer using Nextel's Digital Mobile network is
able to access mobile telephone services, two-way dispatch (marketed as Nextel's
Direct Connect(SM) service), paging and alphanumeric short-messaging service,
and in the future is expected to be able to access data transmission. Nextel is
implementing its Digital Mobile networks utilizing digital technology developed
by Motorola (such technology is referred to as the "integrated Digital Enhanced
Network" or "iDEN"). As of June 30, 1997, Nextel's Digital Mobile networks were
operating in major metropolitan market areas throughout the United States in
which approximately 50% of the total United States population lives or works.

<PAGE>   8
 
     Prior to the second quarter of 1996, Nextel implemented its Digital Mobile
networks in its market areas using Motorola's first generation iDEN technology.
During that time frame, Nextel encountered certain technology and system
performance issues relating primarily to the voice transmission quality of the
mobile telephone service. In response to these issues, Nextel and Motorola took
action on several fronts to address system performance issues in general, and
voice transmission quality concerns in particular. See "Risk
Factors -- Implementation of Digital Mobile Networks Subject to Risks of
Developing Technology." Additionally, Nextel, together with Motorola, in 1995
began pursuing a program directed toward the development and deployment of
modifications to the first generation iDEN technology platform, which
modifications were targeted specifically at improving the voice transmission
quality of the mobile telephone service. Nextel commenced the full-scale
commercial launch of its first Digital Mobile networks incorporating the
modified iDEN technology (referred to herein as "Reconfigured iDEN") in the
Chicago metropolitan market late in the third quarter of 1996 and has since
deployed the Reconfigured iDEN technology throughout its Digital Mobile
networks. To date, the Company's Digital Mobile network is operational in
markets in which over 50% of the United States population lives or works,
providing coverage in and around major metropolitan areas, including New York,
Los Angeles, Chicago, Washington, D.C., Atlanta, Boston, Denver, Detroit,
Dallas/Fort Worth, Houston, San Francisco, Miami/Fort Lauderdale, Tampa/St.
Petersburg, Orlando, Jacksonville, Pittsburgh, Cleveland, Columbus and Salt Lake
City. Later in 1997, the Company plans to expand network coverage to other major
metropolitan areas, including San Antonio, Cincinnati and Austin. Based on its
current plans and construction schedules, the Company expects that its Digital
Mobile network will be operational in markets in which approximately 85% of the
United States population lives or works by the end of 1998.
 
     Since December 31, 1994, the number of subscriber units in service on
Nextel's Digital Mobile network has increased significantly, reflecting the
commencement of Digital Mobile network service in certain markets, increased
sales in markets in which Digital Mobile network services are provided and, to a
limited extent, acquisitions. As a result, the number of subscriber units in
service on Nextel's Digital Mobile network increased from 13,500 at December 31,
1994, to 85,000 at December 31, 1995, to 300,300 at December 31, 1996 and to
624,400 at June 30, 1997. Nextel's business and marketing strategy for its
Digital Mobile networks continues to be based on, and reflect, a principal focus
on multi-service business users in its markets with Digital Mobile networks.
 
     During 1996 and 1997, Nextel also significantly expanded its operations and
investments involving wireless communications service providers outside the
United States, which are conducted under or are coordinated by or through Nextel
International, Inc. (formerly known as McCaw International, Ltd., "Nextel
International"), an indirect, wholly owned subsidiary of Nextel. With the
exception of the equity interests held by Nextel and by Nextel International in
Clearnet Communications, Inc. ("Clearnet"), a major provider of analog and
digital SMR wireless communications services throughout Canada, and the holder
of one of the two nationwide 30 MHz personal communications services ("PCS")
licenses awarded in Canada, Nextel International's subsidiaries or other
entities in which Nextel International holds equity or equivalent interests own
and operate wireless communications systems in Latin America and Asia. Nextel
International's operating companies currently provide a variety of analog or
digital wireless communications services in certain major metropolitan areas in
Argentina, Brazil, Mexico, the Philippines and Shanghai, China.
 
     Nextel's principal executive and administrative facility is located at 1505
Farm Credit Drive, McLean, Virginia 22102, and its telephone number is (703)
394-3000.
 
BUSINESS PLAN
 
     Nextel is implementing its recently revised business plan, which
contemplates an accelerated deployment during 1997 and 1998 of the Reconfigured
iDEN technology platform throughout markets in the United States in which the
Company intends to establish Digital Mobile networks (including primary
connecting routes between certain markets). Nextel estimates that system
infrastructure and other system capital costs to be incurred during the period
from March 31, 1997 through the end of 1998 to implement the business plan would
be approximately $1,450,000,000. See "Risk Factors -- Nextel to Require
Additional Financing." Nextel believes that the implementation of the
accelerated build-out contemplated by its business plan will
                                        6
<PAGE>   9
 
better position Nextel both to achieve its strategic objectives relating to its
U.S. operations and to prepare for emerging competition in the wireless
communications industry, especially from certain current operators that, on
their existing cellular frequencies or on PCS frequencies, are in the process of
converting their wireless communications systems to digital technology formats
and are moving to provide "nationwide coverage" on the resulting systems. Nextel
believes that a significant strategic advantage may exist in being "first to
market," particularly in comparison to the new "entrepreneur block" PCS
licensees and other existing or potential regional wireless communications
service providers, which may encounter significant financial and other
challenges in replicating or overtaking Nextel's industry position assuming
Nextel successfully concludes its nationwide Digital Mobile network build-out
plan and develops a sufficient customer base in its markets. Nextel already has
taken a number of significant steps to implement this business plan (including
obtaining modifications to certain terms contained in the Old Indentures (as
herein defined) to provide the flexibility required to assemble and utilize the
necessary financing for such business plan), and further actions currently are
underway to reach that objective. Nextel's ability to fully implement its
business plan will depend, among other things, on certain actions by third
parties, which cannot be assured. See "Risk Factors -- Nextel to Require
Additional Financing" and "-- Forward Looking Statements."
 
RECENT DEVELOPMENTS
 
     New Senior Notes Issuance.  On September 17, 1997, Nextel completed the
sale of $840,000,000 principal amount at maturity of Senior Redeemable Discount
Notes due 2007 (the "New Senior Notes"). The issue price of the New Senior
Notes, which mature on September 15, 2007, was $595.57 per $1,000 principal
amount at maturity (generating approximately $500,300,000 in aggregate gross
proceeds), representing a yield to maturity of 10.65% computed on a semi-annual
bond equivalent basis from the date of issuance. Nextel received approximately
$486,000,000 in net cash proceeds from the sale of the New Senior Notes (the
"New Senior Notes Proceeds").
 
     Cash interest will not accrue on the New Senior Notes prior to September
15, 2002. Commencing September 15, 2002, cash interest on the New Senior Notes
will be payable on March 15 and September 15 of each year at a rate of 10.65%
per annum. The New Senior Notes are redeemable, at the option of Nextel at any
time, in whole or in part, on or after September 15, 2002, at specified
redemption prices plus accrued and unpaid interest. In addition, in the event of
one or more sales by Nextel prior to September 15, 2000 of at least $125,000,000
of its capital stock, a portion of the New Senior Notes not to exceed a maximum
of 33 1/3% of the aggregate accreted value of the outstanding New Senior Notes
may be redeemed at Nextel's option within 180 days after such sale from the net
cash proceeds thereof at 110.65% of such accreted value to the date of
redemption. The New Senior Notes are senior unsecured indebtedness of Nextel and
rank pari passu in right of payment with all unsubordinated, unsecured
indebtedness of Nextel, including indebtedness evidenced by the Old Notes (as
defined below), and will be senior in right of payment to all subordinated
indebtedness of Nextel.
 
     The New Senior Notes were issued in a private placement transaction and
have not been registered with the Commission under the Securities Act, and may
not be sold absent registration or an applicable exemption from the registration
requirements. In connection with the issuance of the New Senior Notes, Nextel
has agreed to use its best efforts to file with the Commission and cause to
become effective a registration statement with respect to a registered offer to
exchange the then outstanding New Senior Notes for notes of equal value that
have been registered pursuant to the Securities Act (the "Senior Notes Exchange
Offer"). In the event that the Senior Notes Exchange Offer is not consummated
prior to specified dates, additional incremental interest on the accreted value
of the New Senior Notes will accrue until the Senior Notes Exchange Offer is
consummated or certain other requirements are met.
 
     The terms of the New Senior Notes are set forth in the related indenture
(the "New Indenture") which has been filed with the Commission and is
incorporated by reference herein.
 
     Additional Credit Facilities.  Nextel, Nextel Finance Company, a wholly
owned subsidiary of Nextel ("NFC"), and certain subsidiaries of Nextel have
entered into definitive agreements which became effective on September 4, 1997
with respect to $500,000,000 in additional financing, increasing Nextel's total
secured
                                        7
<PAGE>   10
 
financing capacity under its financing agreements to $2,500,000,000. These
agreements provided for (i) amendments to the existing secured credit facility
with certain banks (as so amended, the "Bank Credit Facility") pursuant to which
$250,000,000 in additional term loans (the "Additional Bank Borrowings") were
made to the Company, (ii) amendments to the existing secured credit facility
with Motorola, NTFC Capital Corporation and certain other lenders (as so
amended, the "Vendor Credit Facility") pursuant to which $50,000,000 in
additional term loans (the "Additional Vendor Borrowings") will be made
available to the Company, subject to the satisfaction or waiver of applicable
borrowing conditions, and (iii) a new credit facility pursuant to which up to
$200,000,000 in additional secured term loans (that are to be second in ranking
to the borrowings made pursuant to the Bank Credit Facility and the Vendor
Credit Facility) will be made available to the Company by Motorola through March
31, 1999 (the "Second Secured Borrowings"), subject to the satisfaction or
waiver of applicable borrowing conditions. Borrowings under the Bank Credit
Facility and the Vendor Credit Facility are ratably secured by liens on assets
of Nextel's domestic operating subsidiaries. The Second Secured Borrowings are
secured (on a second priority basis) by the same collateral package securing
amounts outstanding under the Bank Credit Facility and Vendor Credit Facility.
 
     Giving effect to these amendments and the new credit facility, the
agreement related to the Bank Credit Facility (the "Bank Credit Agreement")
provides for up to $1,905,000,000 of secured financing (consisting of a
$1,085,000 revolving loan and $820,000,000 in term loans), the agreement related
to the Vendor Credit Facility (the "Vendor Credit Agreement") provides for up to
$395,000,000 of secured financing (consisting of a $195,000,000 revolving loan
and $200,000,000 in term loans), and the agreement related to the Second Secured
Borrowings (the "Second Vendor Financing Agreement") provides for up to
$200,000,000 of Second Secured Borrowings, for a total of up to $2,500,000,000
in secured financing.
 
     Exercise of First Motorola Option by McCaw Investor.  On September 3, 1997,
the McCaw Investor acquired 2,000,000 shares of Common Stock from Motorola
pursuant to the exercise of an option granted by Motorola, at a per share price
of $15.50 (the "First Motorola Option"). The First Motorola Option was granted
to the McCaw Investor by Motorola in 1995 in connection with the consummation of
the McCaw Transaction, together with additional options covering 2,000,000 and
5,000,000 shares of Common Stock owned by Motorola, at per share exercise prices
of $18.50 and $21.50, respectively, which will become exercisable by the McCaw
Investor in 1999 and 2001, respectively. There can be no assurance that such
additional options will be exercised in whole or in part by the McCaw Investor.
 
     Preferred Stock Issuance.  On July 21, 1997, Nextel completed the sale of
500,000 shares of 13% Series D Exchangeable Preferred Stock (the "Series D
Preferred Stock") with a liquidation preference of $1,000 per share. Nextel
received approximately $482,000,000 in net cash proceeds from the sale of the
Series D Preferred Stock (the "Preferred Stock Proceeds").
 
     Dividends on the Series D Preferred Stock accrue at an annual rate of 13%
of the liquidation preference, are cumulative from the date of issuance and are
payable quarterly in cash or, on or prior to July 15, 2002, at the sole option
of Nextel, in additional shares of Series D Preferred Stock. The Series D
Preferred Stock is mandatorily redeemable on July 15, 2009 at the liquidation
preference plus accrued and unpaid dividends, and is redeemable in whole or in
part, at the option of Nextel, at any time after December 15, 2005, at a price
equal to the liquidation preference plus accrued and unpaid dividends, and, in
certain circumstances, after July 15, 2002 at specified redemption prices. Up to
35% of the Series D Preferred Stock may be redeemed on or prior to July 15,
2000, in whole or in part, at the option of Nextel in certain circumstances, at
113% of the liquidation preference plus accrued and unpaid dividends from the
proceeds of one or more sales of Common Stock. The Series D Preferred Stock is
also exchangeable, in whole but not in part, at the option of Nextel at any time
after December 15, 2005 and in certain circumstances sooner, into Nextel
subordinated debentures.
 
     The shares of Series D Preferred Stock were issued in a private placement
transaction and have not been registered with the Commission under the
Securities Act, and may not be sold absent registration or an applicable
exemption from the registration requirements. In connection with the issuance of
the Series D Preferred Stock, Nextel has agreed to use its best efforts to file
with the Commission and cause to become effective a registration statement with
respect to a registered offer to exchange the then outstanding Series D
Preferred Stock for an equal number of shares of 13% Series D Exchangeable
Preferred Stock that have been
                                        8
<PAGE>   11
 
registered pursuant to the Securities Act (the "Preferred Stock Exchange
Offer"). In the event that the Preferred Stock Exchange Offer is not consummated
prior to specified dates, the dividend accrual rate applicable to the Series D
Preferred Stock will increase by specified amounts until the Preferred Stock
Exchange Offer is consummated or certain other requirements are met.
 
     Terms of the Series D Preferred Stock are set forth in the Certificate of
Designation which has been filed with the Commission and is incorporated by
reference herein.
 
     Consent Solicitation.  Under the terms of Nextel's five outstanding issues
of Senior Redeemable Discount Notes outstanding prior to 1997 (the "Old Senior
Notes") issued pursuant to respective public indentures as in effect prior to
June 13, 1997 (the "Former Version Indentures"), Nextel and its subsidiaries
that are "restricted subsidiaries" for purposes of such indentures (the
"restricted subsidiaries") could not have incurred debt (other than certain
categories of "Permitted Debt" (as defined in such indentures)) unless certain
tests were met. Because such terms of the Former Version Indentures could have
had the effect of limiting Nextel's ability to borrow the funds necessary to
implement its business plan, Nextel sought the consent of the holders of the Old
Senior Notes to certain amendments to the Former Version Indentures pursuant to
a consent solicitation (the "Consent Solicitation"). On June 13, 1997, Nextel
obtained the consent of the requisite number of holders of the Old Senior Notes
to certain amendments and waivers to specific provisions of the Former Version
Indentures. Also on that date, Nextel and the Trustee under such Former Version
Indentures executed supplemental indentures (the "Supplemental Indentures") to
each of the Former Version Indentures implementing such amendments and waivers.
The Former Version Indentures, as amended and modified by their respective
Supplemental Indentures, are referred to herein as the "Old Indentures" and are
referred to collectively with the New Indenture as the "Nextel Indentures." The
amendments include, among other things, certain modifications to the debt
incurrence limitations of such indentures to allow Nextel to incur additional
indebtedness, by (i) increasing the amount of permitted debt by $350,000,000 and
providing additional flexibility to allocate the total amount of permitted debt
among the existing categories of permitted debt, (ii) allowing Nextel to incur
indebtedness in excess of such permitted debt, in the period prior to January 1,
2000, based on the amount and timing of any net cash proceeds received by Nextel
from new equity issuances (such new equity issuances include the net cash
proceeds received by Nextel in connection with the issuance of the Series D
Preferred Stock, but would exclude equity funds from several identified sources,
including most significantly equity investment proceeds received from affiliates
of Craig O. McCaw in connection with the exercise of the First Option (as
defined below)), and (iii) making Nextel's ability to incur additional
indebtedness on and after January 1, 2000 a function of satisfaction of a new
interest coverage ratio test. See "Risk Factors -- Nextel to Require Additional
Financing." The Supplemental Indentures also authorize Nextel to transfer to its
unrestricted subsidiary group the equity interest in Clearnet currently held
directly by Nextel and also implemented certain technical amendments.
 
     The foregoing statements relating to the Old Indentures are summaries of
the relevant provisions and do not purport to be complete. Where reference is
made to particular provisions of the Old Indentures, such provisions, including
the definitions of certain terms, are incorporated by reference as part of such
summaries, and are qualified in their entirety by such reference. Each of the
Former Version Indentures and the Supplemental Indentures has previously been
filed with the Commission, and each of the Former Version Indentures, as amended
and supplemented by the appropriate Supplemental Indenture, is incorporated by
reference herein.
 
     In connection with the Consent Solicitation, Nextel made consent payments
totalling approximately $67,151,000 to validly consenting holders of the Old
Senior Notes (the "Consenting Holders"). On August 8, 1997, the Commission
declared effective Nextel's registration statement on Form S-3 relating to the
offering of approximately 4,161,000 shares of Common Stock exclusively to
Consenting Holders. Pursuant to such registration statement, Nextel offered such
Common Stock to the Consenting Holders at a per share cash price of $16.14. Such
offering expired on September 9, 1997 and approximately 3,940,000 of the offered
shares of Common Stock were subscribed for by Consenting Holders for an
aggregate purchase price of approximately $63,500,000.

     McCaw Investor Option Exercise.  In April 1997, Nextel and the McCaw
Investor reached a preliminary agreement (which was confirmed in definitive
agreements entered into in June 1997) pursuant to which the McCaw Investor
committed to exercise in full the outstanding option that was scheduled to
expire on July 28, 1997 (the "First Option") to purchase 15,000,000 shares of
Common Stock for an aggregate purchase price of $232,500,000 (the "McCaw Option
Proceeds"). The McCaw Investor exercised the First Option on July 28, 1997. In
connection with the foregoing, the McCaw Investor also agreed to provide up to
$50,000,000 in debt financing (subject to certain conditions) to Nextel (the
"McCaw Investor Borrowings"). See "Risk Factors -- Nextel to Require Additional
Financing." At the present time, however, Nextel is not taking steps to meet the
conditions to access the McCaw Investor Borrowings.
 
     On March 20, 1997, Nextel completed the purchase from an affiliate of
Comcast Corporation ("Comcast") of an option to acquire 25,000,000 shares of
Common Stock, at an exercise price of $16.00 per share (the "Comcast Option"),
for an aggregate purchase price of $25,000,000. In connection with the
agreements relating to the commitment to exercise the First Option, Nextel
reached an agreement with an affiliate of Craig O. McCaw (such affiliate, the
"Purchaser"), pursuant to which the Purchaser acquired, for an aggregate
purchase price of $25,000,000, an option, in replacement of the Comcast Option,
to purchase 25,000,000 shares of Common Stock (the "New Option"), 15,000,000 of
which are purchasable at an exercise price of $16.00 per share and the remaining
10,000,000 of which are purchasable at an exercise price of $18.00 per share, at
any time through July 28, 1998. The New Option, and any shares of Common Stock
issued upon exercise thereof, are transferable, subject to certain limitations.
In addition, one direct transferee of the Purchaser will be entitled to
designate one nominee for election to Nextel's Board of Directors, provided that
such party (i) has exercised the transferred portion of the New Option and
continues to own at least 10,000,000 shares of Common Stock obtained on such
exercise, (ii) is not an affiliate of Craig O. McCaw and (iii) does not hold a
5% or greater equity ownership interest in any entity that provides
terrestrial-based wireless communications services in competition with Nextel in
any of its markets. Shares issuable upon exercise of the New Option will be
entitled to certain demand and piggyback registration rights, which would be
assignable to transferees in certain circumstances. There can be no assurance
that the Purchaser or any transferee will elect to exercise the New Option. See
"Risk Factors -- Forward Looking Statements." The arrangements pertinent to the
New Option, the exercise of the First Option and the McCaw Investor Borrowings
are set forth in definitive agreements entered into among the relevant parties,
which definitive agreements have been filed with the Commission and are
incorporated herein by reference.

                                  RISK FACTORS
 
     The following risk factors may affect the value of the Common Stock and
therefore should be considered by prospective investors, in conjunction with the
other information included and incorporated by reference in this Prospectus,
before making an investment decision. See also "-- Forward Looking Statements."
 
HISTORY OF AND FUTURE EXPECTATIONS OF LOSSES AND NEGATIVE CASH FLOW
 
     The activities of Nextel since its inception in 1987 have been concentrated
on the acquisition and operation of SMR businesses and the development of
Digital Mobile networks. Nextel has incurred net losses since its inception,
including net losses of approximately $556,020,000 for the year ended December
31, 1996 and approximately $482,473,000 for the six months ended June 30, 1997.
Nextel had an accumulated deficit totalling approximately $1,617,724,000 at June
30, 1997. Nextel anticipates that it will continue to experience significant net
losses and significant negative net cash flow during the ongoing start up phase
of the Digital Mobile networks over the next several years. Nextel's ability to
arrange sufficient equity and/or debt financing or to generate sufficient
revenue to cover its operating and capital needs is subject to a number of risks
and contingencies. Accordingly, there can be no assurance as to whether or when
Nextel's operations will become profitable. See "-- Nextel to Require Additional
Financing" and "-- Forward Looking Statements."
 
RISKS OF IMPLEMENTATION OF DIGITAL MOBILE NETWORKS
 
     The implementation of Digital Mobile networks involves systems design, site
procurement, construction, electronics installation, receipt of necessary FCC
and other regulatory approvals, channel recovery (freeing a certain number of
800 MHz frequencies from SMR analog traffic) and initial systems optimization
prior to commencing commercial service. Each stage can take from several weeks
to several months and involves various risks and contingencies, the outcome of
which cannot be predicted. There can be no assurance that Nextel will be able to
implement Digital Mobile networks (where such networks are not already in
commercial operation) in any particular market in accordance with its current
plans and schedules. See "-- Forward Looking Statements."
 
IMPLEMENTATION OF DIGITAL MOBILE NETWORKS SUBJECT TO RISKS OF DEVELOPING
TECHNOLOGY
 
     Currently, there are three principal digital technology formats that are
being assessed or proposed for deployment or deployed currently by providers of
cellular telephone service or by certain entities that have been awarded PCS
licenses to provide wireless communications services in the United States. Such
formats are known as Time Division Multiple Access ("TDMA") digital transmission
technology, Code Division Multiple Access ("CDMA") digital transmission
technology and GSM-PCS, which is an updated, upbanded PCS version of the
TDMA-based digital technology format known as Global System for Mobile
Communications ("GSM"). Although TDMA, CDMA and GSM-PCS are digital transmission
technologies, and thus share certain basic characteristics and areas of contrast
to analog transmission technology, TDMA, CDMA and GSM-PCS are not compatible or
interchangeable with each other.
 
     The Motorola proprietary first generation iDEN technology originally
incorporated in Nextel's Digital Mobile networks is known as "six-time slot
TDMA." Although based on the TDMA technology format, this first generation iDEN
technology differs in a number of significant respects from the TDMA technology
versions being assessed or deployed by cellular operators and PCS licensees in
the United States, which differences may have important consequences.
Additionally, unlike the three-time slot TDMA technology format being utilized
for the mobile telephone function in the Reconfigured iDEN technology platform
or the three-time slot TDMA technology format being utilized by certain cellular
providers, the first generation iDEN technology, as well as the "six-time slot
TDMA" technology utilized for the two-way dispatch function in the Reconfigured
iDEN technology platform, can carry up to six (rather than three) voice and/or
control paths per channel.
 
     Although Nextel believes that TDMA technology, on balance, is superior to
analog technology that is used in traditional SMR systems, the use of digital
technology in general involves certain performance trade-offs, for example, in
various characteristics affecting voice quality and fidelity. These trade-offs
may have an
 
                                       13
<PAGE>   16
 
effect on customer acceptance of iDEN technology. The use of six-time and
three-time slot TDMA technology in combination with Nextel's re-use of its
licensed frequencies in a cellular-type system design permits Nextel to utilize
its current holdings of spectrum more efficiently. Efficient utilization of
spectrum is an important objective generally because less spectrum is available
in the SMR band than is or will be licensed to each cellular and certain PCS
operators in each market. Reconfigured iDEN, which is designed to use three time
slots per channel for the mobile telephone service, results in a reduction in
channel capacity compared to the capacity achievable using first generation iDEN
technology for mobile telephone service.
 
     Any difference that may from time to time exist between the technology
deployed in Nextel's Digital Mobile networks and competitive technologies then
deployed by other wireless communications service providers, such as analog,
CDMA, TDMA, GSM-PCS or other transmission technology formats that may be
developed in the future, may affect customer acceptance of the services offered
by Nextel. In the future, a digital transmission technology other than TDMA may
gain acceptance sufficient to adversely affect the resources devoted by third
parties to developing or improving TDMA-based technologies. In addition,
existing digital cellular technology formats including cellular TDMA cannot
currently be utilized on Nextel's present SMR spectrum holdings. Accordingly, if
any improvements were to be made to such currently existing digital cellular
technology formats, the prospect of achievement of parallel improvements in the
TDMA-based iDEN technology presently utilized by Nextel is not certain. See
"-- Forward Looking Statements."
 
     Customer acceptance of the services offered by Nextel will be affected not
only by technology-based differences, but also by the operational performance
and reliability of system transmissions on Nextel's Digital Mobile networks.
Nextel implemented Digital Mobile networks in its market areas using Motorola's
first generation iDEN technology prior to the second quarter of 1996. During
that time frame, Nextel encountered certain technology and system performance
issues with respect to system reliability (the percentage of time the system is
operating), system access (how often a user can gain access to the system) and
various characteristics affecting voice transmission quality of mobile telephone
services utilizing Nextel's Digital Mobile networks. Nextel provided discounts
and gave credits to customers in an effort to foster satisfactory customer
relations and delayed both its planned deployment of its Digital Mobile networks
and commencement of aggressive product and service marketing efforts pending
resolution of such system performance and voice quality issues. During this
period Nextel and Motorola also took actions to address system performance
issues in general, and voice transmission quality concerns in particular. These
actions consisted of efforts to enhance the performance of the first generation
iDEN networks in a number of areas that were believed to adversely affect system
performance, perceived voice transmission quality and customer satisfaction, and
included measures as diverse as improvements in system infrastructure and
subscriber equipment design and interaction, adjustments in cell site locations
and in radio frequency planning, development of enhanced network load and
traffic management and control systems, and development and deployment of more
sophisticated diagnostic and error correction software. These and other
measures, most of which can be categorized as systems optimization, are expected
to be ongoing activities connected with Nextel's operation of its Digital Mobile
networks. Moreover, Nextel expects that systems optimization, software loading
and planned maintenance activities will be ongoing components of its operation
of the Digital Mobile networks that will periodically require the scheduled
turndown of selected subsystems in Nextel's Digital Mobile networks during
periods of very low system traffic, typically at night or on weekend days. See
"-- Forward Looking Statements."
 
     Nextel's objectives in carrying out the initial phase of system development
and technology enhancements were to achieve satisfactory performance levels in
the areas of system reliability and system access. Nextel believes that its
existing Digital Mobile networks as operated at June 30, 1997, were
demonstrating acceptable performance levels in these areas. Nextel also believes
that the successful national deployment throughout Nextel's Digital Mobile
networks of the Reconfigured iDEN technology, with its accompanying improvements
in the voice quality of the mobile telephone service provided on Nextel's
Digital Mobile networks, should enable Nextel to aggressively market such
services as part of a competitive wireless communications services alternative
to existing cellular telephone and PCS wireless communications services in its
markets. See "-- Forward Looking Statements."
 
                                       14
<PAGE>   17
 
     Motorola has advised Nextel that it contemplates continuing to install
software upgrades and Nextel anticipates it will continue to advise and consult
with Motorola concerning potential measures that could be taken to address any
issues concerning system performance and/or expressed customer satisfaction
levels as revealed by Nextel's continuing system testing and customer surveys.
To the extent Nextel's experience has been derived based on customers in its
markets employing the first generation iDEN technology, who are primarily
oriented to the two-way dispatch service, such experience should not necessarily
be regarded as an accurate predictor of Nextel's experience in the future,
particularly as Nextel continues to implement its planned nationwide roll-out of
the Reconfigured iDEN technology and as Nextel's customer base expands beyond
such group of initial customers. Any inability to address and resolve
satisfactorily performance issues that affect customer acceptance of Digital
Mobile network service could delay or adversely affect the successful
commercialization of the Digital Mobile networks and could adversely affect the
business and financial prospects of Nextel. If Nextel for any reason is unable
to implement Digital Mobile networks and provide service to its target customers
that is competitive with the services of other wireless communications
providers, Nextel would be unable, utilizing its existing analog SMR systems, to
provide mobile telephone services comparable to those provided by other wireless
communications services providers or to achieve significant further subscriber
growth. See "-- Forward Looking Statements."
 
     Nextel anticipates that there will be an ongoing focus on systems and
technology optimization activities directed at achieving improvements in the
overall performance of the Digital Mobile networks and such technology
optimization activities will be a continuing component of normal Digital Mobile
network operation. Moreover, the satisfactory resolution of certain system
performance issues in a particular market or at a particular stage of operation
will not necessarily preclude the need to address those issues again, for
example, as a result of a significant increase in the number of subscribers
using the Digital Mobile networks, and future upgrades or modifications to the
Digital Mobile networks may have unexpected adverse effects on performance
issues previously addressed and resolved. Each of Motorola and Nextel believes,
however, that a large portion of the hardware and software adjustments developed
in the course of system development and technology optimization activities to
address particular issues, and the resulting system performance improvements
realized, should be applicable to similar issues in different markets.
Nevertheless, as is often the case in the deployment of wireless communications
networks, it should be expected that there will be market-specific
characteristics, such as local terrain, topography, the number of licensed
frequencies, the utilization of adjacent radio frequencies and other factors,
that will require customized optimization activities to address related system
performance issues successfully. See "-- Forward Looking Statements."
 
     Pursuant to the second amendment to the existing equipment purchase
agreements between Nextel and Motorola entered into in connection with the McCaw
Transaction (the "Second Equipment Agreement Amendment"), Motorola agreed to use
its best efforts to develop, and Nextel agreed to implement, Reconfigured iDEN.
The Reconfigured iDEN development and deployment activities to date have
proceeded in a timely and satisfactory manner, and Nextel believes that the
Reconfigured iDEN development program contemplated by the Second Equipment
Agreement Amendment is substantially complete. However, no assurance can be
given that any further modifications or enhancements to the Reconfigured iDEN
technology will be developed successfully, or that any such modifications or
enhancements, if developed, would be deployed in Nextel's Digital Mobile
networks or, if deployed, would perform successfully. Moreover, no assurance can
be given that the Reconfigured iDEN technology, as it currently exists or as it
may be further modified or enhanced in the future, will satisfy customer
requirements, or that Nextel's mobile telephone services utilizing such
Reconfigured iDEN technology will be regarded as competitive in the wireless
communications services markets as such markets currently exist and as they are
expected to develop in the future. See "-- Forward Looking Statements."
 
NEXTEL TO REQUIRE ADDITIONAL FINANCING
 
     Nextel anticipates that, for the foreseeable future, it will be utilizing
significant amounts of its available cash for capital expenditures for the
construction of Digital Mobile networks, operating expenses relating both to the
Digital Mobile networks and to the analog SMR networks, potential acquisitions
(including the acquisition of rights to spectrum through the contemplated 800
MHz spectrum auction process), debt service
 
                                       15
<PAGE>   18
 
requirements and other general corporate expenditures. Nextel anticipates that
its cash utilization for capital expenditures and other investing activities and
operating losses will continue to exceed its cash flows from operating
activities over the next several years. During fiscal year 1996, Nextel's
average monthly cash utilization rate for investing activities (principally
attributable to capital expenditures for the build-out of the Digital Mobile
networks) was approximately $33,390,000, and its average monthly operating
losses (exclusive of non-cash items) was approximately $20,400,000. Such average
monthly amounts are not necessarily representative of Nextel's anticipated
experience in such areas and are expected to increase during 1997 and 1998 in
connection with the implementation of Nextel's business plan and the related
accelerated construction of its Digital Mobile networks. During the ongoing
start up phase of its Digital Mobile networks, Nextel expects that it will need
to utilize its existing cash and funding from outside sources to meet its cash
needs resulting from such activities and losses. Nextel's aggregate cash, cash
equivalents and marketable securities at June 30, 1997 totalled approximately
$611,495,000 (however, approximately $449,038,000 of such amount represents
cash, cash equivalents and marketable securities held by Nextel International
and its subsidiaries, which items are not available, due to restrictions
contained in the provisions of the NI Indenture, to fund any of the cash needs
of Nextel's domestic Digital Mobile and analog SMR businesses).
 
     To fully implement an accelerated deployment of its Digital Mobile networks
in the period between March 31, 1997 and December 31, 1998 as described under
"Summary -- The Company -- Business Plan," Nextel would need to obtain
additional amounts of debt or equity financing beyond that available under the
Bank Credit Facility and Vendor Credit Facility (together, the "Bank and Vendor
Credit Facilities") and the Second Vendor Financing Agreement currently in
place. The Bank Credit Agreement currently provides for up to $1,905,000,000 of
secured financing, the Vendor Credit Agreement currently provides for up to
$395,000,000 of secured financing and the Second Vendor Financing Agreement
currently provides for up to $200,000,000 in Second Secured Borrowings, subject
in each case to the satisfaction or waiver of applicable borrowing conditions.
At June 30, 1997, Nextel had drawn $1,441,000,000 of its available financing
under the Bank Credit Facility, and had drawn $227,000,000 of its available
financing under the Vendor Credit Facility. Subsequent to June 30, 1997, Nextel
has applied the aggregate of approximately $1,514,000,000 in Preferred Stock
Proceeds, New Senior Notes Proceeds, the McCaw Option Proceeds, proceeds of the
Additional Bank Borrowings and proceeds from the sale of Common Stock to
Consenting Holders to repay a portion of the borrowings outstanding under such
Bank and Vendor Credit Facilities (to the extent the amounts so repaid would be
available for future borrowings thereunder) with the remaining net proceeds
available for general corporate purposes. The remaining funds available for
borrowings under the Bank and Vendor Credit Facilities may be drawn prior to the
final maturity of such facilities in 2003, although the amount available under
such facilities will be reduced to reflect scheduled amortization commencing in
2001. The $200,000,000 in additional funds available under the Second Vendor
Financing Agreement may be drawn as term loans prior to March 31, 1999 and will
mature in 2003.
 
     Nextel has also reached an understanding with Motorola regarding the terms
and conditions pursuant to which Nextel could access up to an additional
$200,000,000 in borrowings that would be required to be ratably secured on an
equal ranking with borrowings pursuant to the Bank Credit Agreement and the
Vendor Credit Agreement (the "Senior Secured Borrowings"). The availability of
the Senior Secured Borrowings is subject to a number of additional conditions,
including the unanimous approval of the secured parties under the Bank Credit
Agreement and the Vendor Credit Agreement. Nextel is not currently taking steps
to meet such additional conditions and, accordingly, Nextel has assumed for
planning purposes that none of the funds constituting the Senior Secured
Borrowings will be available during 1997 and 1998.
 
     The availability of all of such existing and additional financing is
subject to Nextel's satisfying certain requirements under the Old Indentures,
which require Nextel to issue new equity for cash as a condition to obtaining
access to all amounts not constituting "Permitted Debt" (as such term is defined
in the Old Indentures) under the Bank Credit Facility, the Vendor Credit
Facility and the Second Secured Borrowings referred to above. Nextel's receipt
of the $482,000,000 in Preferred Stock Proceeds was sufficient to enable Nextel
to issue the New Senior Notes and still have access to the funding available
under the Bank Credit Facility, the Vendor Credit Facility and the Second Vendor
Financing Agreement under the requirements of the Old Indentures.
 
                                       16
<PAGE>   19
 
     To the extent any of the aforementioned proceeds from equity issuances or
financing arrangements are not available or are not sufficient to meet Nextel's
funding needs, it will be necessary for Nextel to obtain alternate sources of
financing. See "-- Forward Looking Statements." Assuming that Nextel secures
access to all of the available funds under the Bank Credit Facility, the Vendor
Credit Facility and the Second Vendor Financing Agreement and that the New
Option is exercised and Nextel receives the $420,000,000 in proceeds therefrom
(the "New Option Proceeds"), the Company believes that such amounts, coupled
with the Company's available cash and cash equivalents (including the Preferred
Stock Proceeds, the McCaw Option Proceeds, the New Senior Notes Proceeds and the
proceeds from the sale of Common Stock to Consenting Holders), will provide
funds that in the aggregate are expected to be sufficient to implement the
Company's business plan and meet the other cash needs of its domestic business
activities through the end of 1998. Thereafter, Nextel may require substantial
additional financing. See -- "Forward Looking Statements."
 
     The availability of borrowings pursuant to the Bank Credit Facility, the
Vendor Credit Facility and the Second Vendor Financing Agreement is subject to
certain conditions, and there can be no assurance that such conditions will be
met. Moreover, there can be no assurance that the New Option will be exercised
and that Nextel will receive the proceeds therefrom, or that any of the other
outstanding options will be exercised. The Bank Credit Facility, the Vendor
Credit Facility, the Second Vendor Financing Agreement, the Nextel Indentures
and the terms of the Certificate of Designation relating to the Series D
Preferred Stock contain and will continue to contain provisions that operate to
limit the amount of borrowings that may be incurred by Nextel. In addition,
Nextel's capital needs, and its ability to adequately address those needs
through debt or equity funding sources, are subject to a variety of factors that
cannot presently be predicted with certainty, such as the commercial success of
Nextel's Digital Mobile networks incorporating the Reconfigured iDEN technology,
the amount and timing of Nextel's capital expenditures and operating losses and
the market price of the Common Stock. See "-- Forward Looking Statements."
 
     Nextel currently is aware of numerous factors and considerations, any one
or more of which could have a material effect on the timing and/or amount of the
future funding to be required by Nextel, but Nextel cannot currently quantify
with precision either the magnitude or the certainty of the effects associated
with any such factors. These factors include: (i) the timing of the anticipated
800 MHz spectrum auction process (which is currently scheduled to commence in
the fall of 1997), and the amounts required to be bid to acquire any or all of
the available spectrum blocks in the major metropolitan market areas where
Nextel currently operates, or currently plans to operate, its Digital Mobile
network and the amounts that may be required to accomplish retuning or
acquisition of 800 MHz incumbent channels in spectrum blocks that may be
acquired by Nextel in the 800 MHz spectrum auction process; (ii) the uncertainty
with respect to the success and/or timing of the continuing development and
deployment activities relating to the Reconfigured iDEN technology format and,
assuming successful and timely completion of such efforts, the uncertainty with
respect to the success of commercial introduction and customer acceptance of
Nextel's Digital Mobile network services in new market areas using such
technology; (iii) the potential commercial opportunities and risks associated
with implementation of Nextel's accelerated business plan; and (iv) the net
impact on Nextel's capital budget of certain developments currently expected to
increase capital needs (e.g., the additional capital needed if Nextel acquires
for cash additional spectrum in certain markets to increase the capacity and/or
efficiency of Nextel's operating Digital Mobile networks in such markets, the
additional capital needed for more extensive construction of Digital Mobile
networks in additional market areas acquired or that may be acquired in the
future and the expenditures associated with analog SMR station construction
requirements under the currently effective FCC 800 MHz channel licensing
approach) that may be offset (whether wholly or partially) by other developments
anticipated to (or to have the potential to) reduce capital needs (e.g., co-
location of antenna and/or transmitter sites with other providers of wireless
services in the relevant markets, reductions in infrastructure and subscriber
unit prices obtained from Motorola pursuant to the Second Equipment Agreement
Amendment and an agreement entered into on March 27, 1997, alternative and more
economical means for increasing system capacity, other than constructing
additional cell sites and/or installing additional base radios, such as use of
so-called "smart antennas," mini-cells and software-driven and/or system design
performance enhancements). Many of the foregoing involve elements wholly or
partially beyond Nextel's control or influence. Other considerations in addition
to the factors identified above may significantly affect Nextel's decisions to
seek additional financing, including general economic conditions,
 
                                       17
<PAGE>   20
 
conditions in the telecommunications and/or wireless communications industry and
the feasibility and attractiveness of structuring particular financings for
specific purposes (e.g., separate capital-raising activities with respect to
international activities and opportunities). See "-- Forward Looking
Statements."
 
     Nextel has had and may in the future have discussions with third parties
regarding potential equity investments and debt financing arrangements to
satisfy actual or anticipated financing needs. Pursuant to the Motorola
Transaction, Nextel has agreed, under certain circumstances, not to grant
superior governance rights to any third-party investor without Motorola's
consent, which may make securing equity investments more difficult. The ability
of Nextel to incur additional indebtedness (including, in certain circumstances,
indebtedness incurred under the Bank Credit Agreement, the Vendor Credit
Agreement and/or the Second Vendor Financing Agreement) is and will be limited
by the terms of the Nextel Indentures, the Certificate of Designation relating
to the Series D Preferred Stock, the Bank Credit Agreement, the Vendor Credit
Agreement and the Second Vendor Financing Agreement. The Bank Credit Agreement,
the Vendor Credit Agreement and the Second Vendor Financing Agreement also
require Nextel and its relevant subsidiaries at specified times to maintain
compliance with certain financial covenants or ratios including certain
covenants and ratios specifically related to leverage.
 
     At present, other than the existing equity or debt financing arrangements
that have been consummated and/or disclosed, Nextel has no commitments or
understandings with any third parties to obtain any material amount of
additional equity or debt financing. Moreover, no assurances can be made that
Nextel will be able to obtain any such additional financing in the amounts or at
the times such financing may be required, or that, if obtained, any such
financing would be on acceptable terms. Nextel also anticipates that it will
continue to experience significant operating losses and negative net cash flows
during the ongoing start up phase of the Digital Mobile networks over the next
several years. Accordingly, there can be no assurances as to whether or when the
operations of Nextel will become profitable. As a result of Nextel's anticipated
continuing losses, the uncertainty regarding the exercise of options and
warrants and the availability of financing under the Bank and Vendor Credit
Facilities and the Second Vendor Financing Agreement, and the impact of
Reconfigured iDEN and other matters discussed above, there can be no assurance
that Nextel will have adequate capital to implement the nationwide build-out of
its Digital Mobile networks in accordance with its business plan. Failure to
obtain such financing could result in the delay or abandonment of some or all of
the Company's acquisition, development and expansion plans and expenditures,
which could have a material adverse effect on its business prospects. See
"-- Forward Looking Statements."
 
SUCCESS OF NEXTEL IS DEPENDENT ON ITS ABILITY TO COMPETE
 
     Nextel's success depends on its Digital Mobile networks' ability to compete
with other wireless communications systems in each relevant market and its
ability to successfully market integrated wireless communications services.
Nextel is continuing to focus its marketing efforts on attracting customers from
its previously identified targeted groups of potential subscribers, chiefly its
existing analog SMR subscribers and other business users, including current
users of multiple wireless communications services and those new users who may
be attracted to the combination of services made possible by its Digital Mobile
networks.
 
     Following implementation of its Digital Mobile networks and completion of
related system optimization activities, Nextel's Digital Mobile networks will
compete with established and future wireless communications operators in its
efforts to attract customers, dealers and possibly resellers to its service in
each of the markets in which it operates a Digital Mobile network. Nextel
believes that following software upgrades and additional system optimization
efforts and equipment and technology enhancements that occurred during 1996 and
the commercial deployment of the Reconfigured iDEN technology, Nextel's Digital
Mobile networks will have the capacity, functionality and quality of service
necessary to be competitive with current wireless communications services in the
markets in which Nextel operates Digital Mobile networks. Nextel's ability to
compete effectively with other wireless communications service providers,
however, will depend on a number of factors, including the successful deployment
of the Reconfigured iDEN technology platform in its market areas, the continued
satisfactory performance of such technology, the establishment of roaming
service among such market areas and the development of cost effective direct and
indirect channels of distribution for its products and services. Although Nextel
has made significant progress in these areas to date, no assurance can be given
 
                                       18
<PAGE>   21
 
that such objectives will be achieved. See "-- Ability to Manage Growth" and
"-- Forward Looking Statements."
 
     While Nextel believes that the mobile telephone service provided on its
Digital Mobile networks utilizing the Reconfigured iDEN technology is similar in
function to and achieves performance levels competitive with those being offered
by other current wireless communications services providers in Nextel's market
areas, there are (and will in certain cases continue to be) differences between
the services provided by Nextel and by cellular and/or PCS system operators and
the performance of their respective systems. As a result of these differences,
there can be no assurance that services provided on Nextel's Digital Mobile
networks will be competitive with those available from other providers of mobile
telephone services. As part of its marketing strategy, Nextel will continue to
emphasize the benefits to its customers of obtaining an integrated package of
services consisting of mobile telephone service, two-way dispatch, paging and
alphanumeric short-messaging service, and in the future, data transmission.
Neither PCS system operators nor cellular operators currently provide such
integrated services, but recent FCC rulings permit cellular operators to offer
two-way dispatch services. If either PCS system or cellular operators do provide
two-way dispatch services in the future, Nextel's competitive advantage from
using such a marketing strategy may be impaired.
 
     Nextel currently offers its mobile telephone customers the ability to
"roam" among Nextel's existing Digital Mobile network market areas, which as of
June 30, 1997 represented coverage of areas in which approximately 50% of the
United States population lives or works. Accordingly, Nextel will not be able to
provide roaming service comparable to that currently available from cellular
operators, which have roaming agreements covering each other's markets
throughout the United States, unless and until nationwide Digital Mobile
networks build-out is substantially completed. Additionally, certain PCS
operators throughout the United States have announced their intention to
implement agreements to permit roaming among their markets. Moreover, the
cellular systems in each of Nextel's markets, as well as in the markets in which
Nextel expects to provide services in the future, have been operational for a
number of years, currently service a significant subscriber base and typically
have significantly greater financial and other resources than those available to
Nextel. As is true for cellular operators, the interconnection of subscriber
units with the public switched telephone network requires Nextel to purchase
certain exchange and inter-exchange services from telephone companies and
certain other common carriers.
 
     Subscriber units on the Digital Mobile networks are not compatible with
cellular or PCS systems, and vice versa. This lack of interoperability may
impede Nextel's ability to attract cellular or PCS subscribers or those new
mobile telephone subscribers that desire the ability to access different service
providers in the same market. Nextel currently markets a multi-function
subscriber unit that is (and is likely to remain) significantly more expensive
than analog handsets and is (and is likely to remain) somewhat more expensive
than digital cellular or PCS handsets that do not incorporate a comparable
multi-function capability. Accordingly, the prices expected to be charged to
Nextel for the subscriber handsets to be used by Nextel's customers will be
higher than those charged to operators for analog cellular handsets and may be
higher than those charged to operators for digital cellular handsets. Nextel's
multi-function subscriber units, however, are competitively priced compared to
multi-function (mobile telephone service and alphanumeric short-text messaging)
digital cellular and PCS handsets. During the transition to digital technology,
certain participants in the United States cellular industry are offering
subscriber units with dual mode (analog and digital) compatibility. There can be
no assurances that existing analog SMR customers will be willing to invest in
new subscriber equipment necessary to migrate to the Digital Mobile networks.
Over the past several years as the number of wireless communications providers
in Nextel's market areas has increased, the prices of such providers' wireless
service offerings to customers in those markets have generally been decreasing.
The Company may encounter further market pressures to reduce its service
offering prices to respond to particular short term, market specific situations
(such as special introductory pricing packages that may be offered by new
providers launching their service in a market) or to remain competitive in the
event that wireless service providers generally continue to reduce the prices
charged to their customers. Moreover, because many of the cellular operators and
certain of the PCS operators in Nextel's markets have substantially greater
financial resources than Nextel, such operators may be able to offer prospective
customers equipment subsidies or discounts that are substantially greater than
those, if any, that could be offered by Nextel and may be able to offer services
to
 
                                       19
<PAGE>   22
 
customers at prices that are below prices that Nextel is able to offer for
comparable services. Thus, Nextel's ability to compete based on the price of
subscriber units and service offerings will be limited. Nextel cannot predict
the competitive effect that any of these factors, or any combination thereof,
will have on Nextel. See "-- Forward Looking Statements."
 
     Cellular operators and certain PCS operators and entities that have been
awarded PCS licenses each control more spectrum than is allocated for SMR
service in each of the relevant market areas. Each cellular operator is licensed
to operate 25 MHz of spectrum and certain PCS licensees have been licensed for
30 MHz of spectrum in the markets in which they are licensed, while no more than
21.5 MHz is available in the 800 MHz band to all SMR systems, including Nextel's
systems, in those markets. The control of more spectrum gives cellular operators
and such PCS licensees the potential for more system capacity, and, therefore,
more subscribers, than SMR operators, including Nextel. Nextel believes that it
generally has adequate spectrum to provide the capacity needed on its Digital
Mobile networks for the foreseeable future. See "-- Forward Looking Statements."
 
     Each of the markets in which Nextel's Digital Mobile networks operate or
will operate is serviced by multiple other wireless communications service
providers. In each of the markets where Nextel's Digital Mobile networks
operate, Nextel may compete with the two established cellular licensees in such
market and as many as six PCS licensees. The FCC has described PCS as a digital,
wireless communications system consisting of a variety of new mobile and
portable services and technologies, using small, lightweight units. PCS services
may include portable, two-way voice and data services. A substantial number of
the entities that have been awarded PCS licenses are current cellular
communications service providers and joint ventures of current and potential
wireless communications service providers, many of which have financial
resources, subscriber bases and name recognition greater than Nextel. PCS
operators will likely compete with Nextel in providing some or all of the
services available through Nextel's Digital Mobile networks. Additionally,
Nextel expects that existing cellular service providers, some of which have been
operational for a number of years and have significantly greater financial and
technical resources, subscriber bases and name recognition than Nextel, will
continue to upgrade their systems to provide digital wireless communications
services competitive with Nextel's Digital Mobile networks. Nextel also expects
to face competition from other technologies and services developed and
introduced in the future. Nextel cannot predict how these technologies will
develop or what impact, if any, they will have on Nextel's ability to compete
for wireless communications services customers. See "-- Forward Looking
Statements."
 
     The Company currently anticipates that it will rely more heavily on
indirect distribution channels to achieve greater market penetration for its
digital wireless service offerings. As the Company expands its retail subscriber
base through increased reliance on indirect distribution channels, the average
revenue per subscriber unit may decrease.
 
ABILITY TO MANAGE GROWTH
 
     As a result of the commencement of Digital Mobile network service in
certain markets, increased sales in markets in which Digital Mobile network
services are provided and, to a limited extent, acquisitions, the number of
subscriber units in service on Nextel's Digital Mobile network has increased
substantially over the past several years.
 
     The ability of Nextel to continue to add increasing numbers of subscribers
on its Digital Mobile network is dependent on a variety of factors. Among the
more important of such factors is Nextel's ability to successfully plan for
additional system capacity in its market areas at levels adequate to accommodate
anticipated new subscribers and the related increases in system usage. One
important factor influencing system capacity is the amount of spectrum available
to Nextel in a particular market area. Although Nextel intends to continue to
pursue opportunities to acquire additional SMR spectrum in its market areas,
Nextel believes that its present holdings of 800 MHz spectrum are generally
adequate for the current and reasonably foreseeable operation of its Digital
Mobile network.
 
     Additionally, Nextel requires that a sufficient quantity of cell sites,
system infrastructure equipment and subscriber units, of the appropriate models
and types, be available to meet the demands and preferences of
 
                                       20
<PAGE>   23
 
potential subscribers to the Digital Mobile network. To date, Nextel has been
able to secure sufficient cell sites at appropriate locations in its markets to
meet planned system coverage and capacity targets, and also has been able to
obtain adequate quantities of base radios and other system infrastructure
equipment from Motorola and other suppliers, and adequate volumes and mix of
subscriber units and related accessories from Motorola, to meet subscriber and
system loading rates. Although Nextel does not currently foresee (based on,
among other factors, its scheduled system construction and expansion activities
and its anticipated rates of customer and service usage growth) any significant
supply problems in the near term, Motorola is the sole supplier of system
infrastructure equipment and subscriber units and most of the related equipment
required by the Company to construct and operate its Digital Mobile network, and
there can be no assurance that such supply problems or related issues will not
occur in the future.
 
     Nextel's ability to successfully add customers on its Digital Mobile
network depends upon the adequacy and efficiency of its information systems,
business processes and related support functions. Nextel relies on its own
fulfillment processes and related information system resources to accomplish
tasks necessary to initiate service for prospective customers, such as
identifying and provisioning from inventory appropriate subscriber units and
desired accessories, programming subscriber units to support desired functions
and features, registering subscriber units to appropriate authorized users of
the Digital Mobile network and setting up appropriate customer accounts and
other billing records and data.
 
     Due to the multiple wireless service offering packages and the need to
create customized applications (for instance, programming multiple talk groups
for the Direct Connect service), the length of time from customer order to
commencement of service (the "activation cycle") on the Digital Mobile network
has been longer than the activation cycle typically encountered for "off the
shelf" cellular and PCS wireless service offerings. The Company is currently
taking steps to refine, improve and scale-up its customer and service
information reporting, subscriber unit fulfillment, service activation and
billing systems and processes to meet the increased demands that are expected to
be associated with anticipated increases in subscriber growth and Digital Mobile
network wireless systems and service utilization. The Company also is exploring
alternatives to shorten its Digital Mobile network activation cycle, such as
"pre-programming" subscriber units with standardized talk groups and potential
development with Motorola of an "over the air" programming capability for
digital subscriber units. Finally, the Company's customer service functions must
continue to improve the efficiency and speed of their processes to adequately
respond to the needs of a growing customer base on the Digital Mobile network.
Customer reliance on Nextel's customer service functions may increase as more
Digital Mobile network customers are added through indirect distribution
channels.
 
     There can be no assurance that the back-office and support systems and
processes discussed above will achieve levels of capacity, or improvements in
speed and efficiency, sufficient to meet actual customer and network growth and
demands, or will be able to do so on a timely basis. Any inability of the
Company to timely meet Digital Mobile network capacity needs, to have access to
suitable cell sites and infrastructure and subscriber equipment in any one or
more of its market areas, or to develop when and as required improvements or
expansions to its systems and processes adequate to meet desired levels of
customer activation and demand for wireless services on the Digital Mobile
network could decrease or postpone subscriber growth, thereby adversely
affecting Nextel's revenues, business and prospects.
 
RELIANCE ON ONE PRINCIPAL SUPPLIER IN IMPLEMENTATION OF DIGITAL MOBILE NETWORKS
 
     Pursuant to existing equipment purchase agreements first entered into in
1991, as subsequently amended (such equipment purchase agreements, as amended,
being referred to herein as the "Equipment Purchase Agreements"), between Nextel
and Motorola, Motorola provides the iDEN infrastructure and subscriber handset
equipment to Nextel throughout its markets. Nextel expects that it will need to
rely on Motorola for the manufacture of a substantial portion of the equipment
necessary to construct its Digital Mobile networks and handset equipment for the
foreseeable future. The Equipment Purchase Agreements include a commitment from
Nextel to purchase from Motorola a significant amount of system infrastructure
equipment. Nextel has, among other things, agreed (subject to certain
conditions) to purchase and install iDEN equipment during the four-year and
six-year periods beginning on August 4, 1994 sufficient to cover 70% and 85%,
respectively, of the United States population. In addition, subject to the
applicable terms and conditions under
 
                                       21
<PAGE>   24
 
the Second Equipment Agreement Amendment, Nextel has agreed to deploy
Reconfigured iDEN technology and, until August 4, 1999 and subject to certain
conditions, to purchase from Motorola at least 50% of the base radios Nextel
purchases in any calendar year. See "-- Success of Nextel is Dependent on its
Ability to Compete" and "-- Forward Looking Statements." Such commitments are in
addition to amounts purchased from Motorola or for which Nextel or companies
acquired by Nextel had placed orders with Motorola prior to August 4, 1994,
which orders have become obligations of Nextel.
 
     The Second Equipment Agreement Amendment limits Nextel's ability to deploy
a "Switch in Technology" which, under the Second Equipment Agreement Amendment,
is defined to mean a decision by Nextel before August 4, 1999 to install and use
digital radio frequency technology as an alternative to iDEN on more than 25% of
its SMR channels in the 806-824 MHz band in one or more of its top 20 domestic
markets, or the utilization by Nextel of any of its SMR channels for voice
interconnect on certain United States cellular and/or PCS radio telephony
standards. Nextel may not implement such a Switch in Technology unless (1)
Nextel determines that the iDEN or Reconfigured iDEN equipment fails to meet
certain performance specifications established in the Second Equipment Agreement
Amendment, which failure materially adversely affects the commercial viability
of the technology to provide reliable services as intended by Motorola and
Nextel, and Motorola does not cure such failure within six months after
receiving notice thereof, or (2) Nextel or the McCaw Investor offers to acquire
the remainder of Motorola's shares of Common Stock at a per share price of at
least 110% of the average of the closing prices of the Common Stock over the 30
trading days preceding the public announcement by Nextel of the decision to
implement such a Switch in Technology. In either case, if Motorola manufactures
(or elects to manufacture) the alternate technology Nextel elects to deploy,
Nextel must purchase 50% of its infrastructure requirements and 25% of its
subscriber equipment requirements from Motorola for three years, provided such
equipment is competitive in price and performance to the equipment utilizing or
incorporating such alternate technology then offered by other manufacturers.
 
     It is expected that for the next few years of Digital Mobile network
operations by Nextel, Motorola and competing manufacturers who are licensed by
Motorola will be the only manufacturers of subscriber equipment that is
compatible with Nextel's Digital Mobile networks. The Equipment Purchase
Agreements between Nextel and Motorola first entered into in 1991, as
subsequently amended by, among others, the amendment entered into in connection
with the Motorola Transaction (the "Prior Equipment Agreement Amendment")
provide for the licensing by Motorola of interfaces relating to infrastructure
and subscriber equipment and of additional manufacturers for subscriber
equipment. In connection with the Second Equipment Agreement Amendment, Motorola
further agreed to negotiate to enter into licenses with at least one alternative
manufacturer of iDEN infrastructure equipment. Currently, however, there are no
arrangements in effect with any additional manufacturers to supply Nextel with
alternative sources for either iDEN system infrastructure or subscriber
equipment.
 
NEXTEL'S PROSPECTS ARE DEPENDENT ON GOVERNMENTAL REGULATION
 
     The licensing, operation, acquisition and sale of Nextel's SMR businesses
are regulated by the FCC. FCC regulations have undergone significant changes
during the last three years and continue to evolve as new FCC rules and
regulations are adopted pursuant to the Omnibus Budget Reconciliation Act of
1993 and the Telecommunications Act of 1996. Nextel's ability to conduct its
business is dependent, in part, on its compliance with FCC rules and
regulations. Future changes in regulations or legislation affecting Digital
Mobile network service and Congress' and the FCC's recent allocation of
additional Commercial Mobile Radio Services spectrum could materially adversely
affect Nextel's business. See "-- Forward Looking Statements."
 
NEXTEL'S ASSETS PRIMARILY CONSIST OF INTANGIBLE FCC LICENSES
 
     Nextel's assets consist primarily of intangible assets, principally FCC
licenses, the value of which will depend significantly upon the success of
Nextel's business and the growth of the SMR and wireless communications
industries in general. In the event of default on indebtedness or liquidation of
Nextel, there
 
                                       22
<PAGE>   25
 
can be no assurance that the value of these assets will be sufficient to satisfy
its obligations. Nextel had a negative net tangible book value of approximately
$1,665,584,000 as of June 30, 1997.
 
NEXTEL SUSCEPTIBLE TO CONTROL BY SIGNIFICANT STOCKHOLDERS
 
     Based on securities ownership information relating to Nextel as of July 31,
1997, and giving effect (on such date) to the conversion of the outstanding
shares of Nextel's preferred stock and Class B Non-Voting Common Stock, par
value $0.001 per share (the "Non-Voting Common Stock"), and the exercise in full
of (i) two separate options held by the McCaw Investor exercisable for periods
of four and six years, respectively, from July 28, 1995, to acquire an aggregate
of up to 20,000,000 shares of Common Stock at exercise prices ranging from
$18.50 to $21.50 per share, (the "McCaw Options"), (ii) the option held by Eagle
River, Inc., an affiliate of the McCaw Investor ("Eagle River"), to purchase an
aggregate of 1,000,000 shares of Common Stock at an exercise price of $12.25,
which option vests over a five-year period from April 4, 1995 (the "Incentive
Option"), (iii) the New Option issued to an affiliate of Mr. McCaw to acquire
15,000,000 shares at $16.00 per share and 10,000,000 shares at $18.00 per share
prior to July 29, 1998, (iv) the options granted on July 28, 1995 to the McCaw
Investor by Motorola to purchase up to 9,000,000 shares of Common Stock over a
six-year period (the "McCaw Investor/Motorola Options"), including the 2,000,000
shares of Common Stock that the McCaw Investor acquired by exercise of the First
Motorola Option in a transaction that closed on September 3, 1997, and (v) a
warrant held by Motorola to purchase 2,890,000 shares of Common Stock, the McCaw
Investor would hold approximately 30.2% and Motorola would hold approximately
15.7% of the Common Stock that would be outstanding as of such date.
 
     In connection with the consummation of the McCaw Transaction and pursuant
to the Securities Purchase Agreement dated as of April 4, 1995, as amended,
among Nextel, the McCaw Investor and Mr. 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. Additionally, the McCaw Investor is entitled
to have a majority of the members of the Operations Committee of the Board of
Directors selected from the McCaw Investor's representatives on the Board of
Directors. The Operations Committee has the authority to formulate key aspects
of Nextel's business strategy, including decisions relating to the technology
used by Nextel (subject to existing equipment purchase agreements),
acquisitions, the creation and approval of operating and capital budgets and
marketing and strategic plans, approval of financing plans, endorsement of
nominees to the Board of Directors and committees thereof and nomination and
oversight of certain executive officers. As a result, based upon the McCaw
Investor's stock ownership position, as well as its ability to designate at
least 25% of the members of the Board of Directors and control the Operations
Committee, the McCaw Investor is in a position to exert significant influence
over Nextel's affairs. The Board of Directors retains the authority to override
actions taken or proposed to be taken by the Operations Committee, subject, in
certain circumstances, to certain financial consequences. The creation and
existence of the Operations Committee does not change the normal fiduciary
duties of the Board of Directors, including fiduciary duties in connection with
any proposal to override any action of or to terminate the Operations Committee,
whether or not such action would give rise to such financial consequences.
Although Motorola is entitled to nominate two directors to the Board of
Directors, presently only one person designated by Motorola is a Nextel
director. Pursuant to an amendment to the Plan of Contribution and Merger dated
as of April 4, 1995, by and among Nextel, Motorola and certain subsidiaries of
Motorola (the "Motorola Amendment"), Motorola has agreed to support the
decisions and recommendations of the Operations Committee and to vote the shares
of Common Stock held by it accordingly, subject to (1) the right of any Motorola
designated Nextel directors to vote in a manner consistent with their fiduciary
duties and (2) the right of Motorola to vote its shares as it determines
necessary with respect to issues that conflict with Motorola's corporate ethics
or that present conflicts of interest, or in order to protect the value or
marketability of the shares of Common Stock held by it.
 
     Based upon their respective ownership positions, if the McCaw Investor and
Motorola chose to act together, such parties could have a sufficient voting
interest in Nextel, among other things, to (1) exert effective control over the
approval of amendments to Nextel's Restated Certificate of Incorporation, as
amended, mergers, sales of assets or other major corporate transactions as well
as other matters submitted for stockholder vote, (2) defeat a takeover attempt
and (3) otherwise control whether particular matters are
 
                                       23
<PAGE>   26
 
submitted for a vote of the stockholders of Nextel. Although Motorola has made
certain commitments as described in the last sentence of the preceding
paragraph, Nextel is not aware of any current agreements among the McCaw
Investor and Motorola with respect to the ownership or voting of Common Stock
and neither Motorola nor the McCaw Investor has indicated to Nextel that it has
any present intention to seek to exercise such control. Pursuant to the McCaw
Securities Purchase Agreement, the McCaw Investor has agreed that it will not
vote for any nominee to the Board of Directors other than persons it is entitled
to designate under the terms of the securities it owns or of the McCaw
Securities Purchase Agreement. Upon request of Nextel, the McCaw Investor has
also agreed to cause shares of Common Stock, the voting of which is controlled
by it or its affiliates, to be voted in a manner proportionate to the votes of
other holders of Common Stock in the election of directors so designated by the
Board of Directors.
 
     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 telecommunications services that
could potentially compete with Nextel. Under the McCaw Securities Purchase
Agreement, the McCaw Investor, Mr. McCaw and their Controlled Affiliates (as
defined in the McCaw Securities Purchase Agreement) may not, for a period of
time after consummation of the McCaw Transaction, 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 in accordance with the
provisions of the McCaw Securities Purchase Agreement. Such limitation is
subject to certain limited exceptions, including certain existing securities
holdings and relationships (and expressly including Mr. McCaw's investment in
AT&T resulting from AT&T's acquisition of McCaw Cellular Communications, Inc.,
which investment may not exceed 3% of the outstanding stock of AT&T). Such
restrictions terminate on the later to occur of July 28, 2000 or one year after
the termination of the Operations Committee. See "-- Potential Conflict of
Interest Relationship with Motorola."
 
POTENTIAL DILUTION FROM PENDING AND FUTURE TRANSACTIONS
 
     As indicated elsewhere in this Prospectus, Nextel has commitments, and from
time to time may enter into additional commitments, to issue a substantial
number of new shares of Common Stock. The shares that are subject to such
issuance commitments, to a large degree, either will be issued in registered
transactions and thus will be freely tradeable, or will be subject to grants of
registration rights which, if and when exercised, would result in such shares
becoming freely tradeable. Additionally, to incur debt in excess of permitted
debt levels prior to January 1, 2000, pursuant to the amendments to the Nextel
Indentures as described above (see "Summary -- The Company -- Recent
Developments -- Consent Solicitation"), Nextel would be required to issue new
equity.
 
     As of July 31, 1997, there were approximately 282,311,634 shares of Common
Stock outstanding (assuming the conversion of the outstanding shares of Nextel's
Non-Voting Common Stock and Nextel's preferred stock), on a primary, rather than
a fully diluted, basis, and approximately 354,900,135 shares of Common Stock
would have been outstanding assuming the exercise of all options (including
employee options, warrants initially issued to Motorola to purchase 3,000,000
shares, the options to purchase an aggregate of 21,000,000 shares pursuant to
the McCaw Options and the Incentive Option and an aggregate of 25,000,000 shares
pursuant to the New Option), warrants and other existing rights to acquire
Common Stock outstanding on such date.
 
     On April 29, 1996, the Commission declared effective Nextel's registration
statement on Form S-4, covering 10,000,000 shares of Common Stock, or warrants
to acquire such shares, which contemplates issuances from time to time on a
"shelf" basis in accordance with Rule 415(a)(1)(viii) promulgated under the
Securities Act in connection with acquisitions of other businesses, properties
or securities in business combination transactions. As of the date hereof,
Nextel has issued 186,621 shares of Common Stock pursuant to such registration
statement. In addition, on August 7, 1997, the Commission declared effective
Nextel's registration statement on Form S-4 covering up to 9,221,523 shares of
Common Stock in connection with the pending acquisition of Pittencrieff
Communications, Inc., which is expected to close in the fourth quarter of 1997.
 
                                       24
<PAGE>   27
 
     Pursuant to the McCaw Securities Purchase Agreement, the McCaw Investor was
granted anti-dilutive rights with respect to certain Nextel share issuances (the
"McCaw Purchase Right"). An increase in the number of shares of Common Stock
that will become available for sale in the public market may adversely affect
the market price of Common Stock.
 
SHARES ELIGIBLE FOR FUTURE SALE
 
     Existing holders of Common Stock generally may freely resell their shares
except to the extent that they are deemed to be affiliates of Nextel or certain
predecessor companies for purposes of Rule 144 or Rule 145 promulgated under the
Securities Act. Nextel has also granted registration rights with respect to a
significant number of its shares outstanding on a fully diluted basis, including
shares of Common Stock issuable upon conversion of securities issued in, or upon
exercise of options granted in, the Motorola Transaction and the McCaw
Transaction. The exercise of registration rights by persons entitled thereto
would permit such persons to sell such shares without regard to the limitations
of Rule 144. An increase in the number of shares of Common Stock that will
become available for sale in the public market may adversely affect the market
price of Common Stock.
 
DIVIDEND POLICY LIMITS EXPECTATION OF FUTURE DIVIDENDS
 
     Nextel has not paid any dividends on Common Stock and does not plan to pay
dividends on Common Stock for the foreseeable future. The Nextel Indentures, the
Bank Credit Agreement, the Vendor Credit Agreement and the Second Vendor
Financing Agreement presently prohibit, and are expected to operate so as to
continue to prohibit, Nextel from paying dividends. In addition, the collateral
security mechanisms and related provisions associated with the Bank and Vendor
Credit Facilities and the Second Vendor Financing Agreement limit the amount of
cash available to make dividends, loans and cash distributions to Nextel from
Nextel's subsidiaries that operate Digital Mobile networks in Nextel's markets.
Accordingly, while such restrictions are in place, any profits generated by such
subsidiaries will not be available to Nextel for, among other purposes, payment
of dividends.
 
POTENTIAL CONFLICT OF INTEREST RELATIONSHIP WITH MOTOROLA
 
     Motorola and its affiliates have and currently are engaged in wireless
communications businesses, and may in the future engage in additional such
businesses, which are or may be competitive with some or all of the services
offered by Nextel's Digital Mobile networks, although the Motorola Land Mobile
Products Sector ("Motorola LMPS") may not, prior to July 28, 1998, make use
(with certain limited exceptions) of the customer lists conveyed by Motorola to
ESMR in connection with the Motorola Transaction to solicit subscribers for any
800 MHz SMR commercial mobile voice business owned or managed by Motorola LMPS
in the continental United States. Pursuant to the Second Equipment Agreement
Amendment, Motorola has agreed that until July 1998, Motorola LMPS will not
solicit other iDEN customers and neither Motorola LMPS nor Motorola's credit
corporation subsidiary will make any equity investment in, or provide
equipment/vendor financing to, certain iDEN customers with respect to purchases
of iDEN equipment.
 
     In light of the competitive posture of Motorola, Nextel and Motorola have
agreed that any information relating to Nextel's business plans and projections
will be used by Motorola only for purposes of ensuring compliance with Nextel's
obligations under the various equipment purchase agreements and financing
agreements between Nextel and Motorola. Motorola has designated one director to
the Board of Directors and, hence, such director has access to Nextel's business
plans subject to certain confidentiality restrictions.
 
     Although Nextel believes that its equipment purchase and financing
relationship with Motorola has been structured to reflect the realities of
purchasing and borrowing from a competitor, there can be no assurance that the
potential conflict of interest will not adversely affect Nextel in the future.
Moreover, Motorola's role as a significant stockholder of Nextel, in addition to
its role as a major creditor and supplier, also creates potential conflicts of
interest, particularly with regard to significant transactions.

CONCERNS ABOUT MOBILE COMMUNICATIONS HEALTH RISK MAY AFFECT PROSPECTS OF NEXTEL
 
     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 investigated 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. The actual or perceived risk of
mobile communications devices could adversely affect Nextel through a reduced
subscriber growth rate, a reduction in subscribers, reduced network usage per
subscriber or through reduced financing available to the mobile communications
industry.
 
FORWARD LOOKING STATEMENTS
 
     "SAFE HARBOR" STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT
OF 1995:  A number of the matters and subject areas discussed in the foregoing
"Risk Factors" section of this Prospectus that are not historical or current
facts deal with 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 Nextel's actual future experience involving any one or more of such
matters and subject areas. Nextel has attempted to identify, in context, certain
of the factors that it currently believes may cause actual future experience and
results to differ from Nextel's current expectations regarding the relevant
matter or subject area. The operation and results of Nextel's wireless
communications business also may be subject to the effect of other risks and
uncertainties in addition to the relevant qualifying factors identified
elsewhere in the foregoing "Risk Factors" section, including, but not limited
to, general economic conditions in the geographic areas and occupational market
segments that Nextel is targeting for its Digital Mobile network service, the
availability of adequate quantities of system infrastructure and subscriber
equipment and components to meet Nextel's service deployment and marketing plans
and customer demand, the success of efforts to improve and satisfactorily
address any issues relating to Digital Mobile system performance, the successful
nationwide deployment of the Reconfigured iDEN technology, the ability to
achieve market penetration and average subscriber revenue levels sufficient to
provide financial viability to the Digital Mobile network business, Nextel's
ability to timely and successfully accomplish required scale-up of its billing,
customer care and similar back-room operations to keep pace with customer growth
and increased system usage rates, access to sufficient debt or equity capital to
meet Nextel's operating and financing needs, the quality and price of similar or
comparable wireless communications services offered or to be offered by Nextel's
competitors, including providers of cellular and PCS service, future legislative
or regulatory actions relating to SMR services, other wireless communications
services or telecommunications generally and other risks and uncertainties
described from time to time in Nextel's reports filed with the Commission,
including the Annual Report on Form 10-K for the fiscal year ended December 31,
1996 and the Quarterly Reports on Form 10-Q for the quarters ended March 31,
1997 and June 30, 1997.
 
                                USE OF PROCEEDS
 
     Assuming all of the Warrants are exercised, the net proceeds of the
Offering are estimated to be approximately $52,738,745 after deducting estimated
expenses of the Offering of $85,000. The Company intends to use the net proceeds
of the Offering for general corporate purposes. The net proceeds to the Company
from the Offering will be realized only if and to the extent any of the Warrants
are exercised. There can be no assurance that any of the Warrants will be
exercised or as to the timing of such exercises.
 
                                    DILUTION
 
     The following tables set forth certain information concerning net tangible
book value and dilution as of June 30, 1997. The net tangible book value of the
Common Stock as of June 30, 1997 was $(1,665,584,000) or $(6.25) per share. Net
tangible book value per share represents the amount of the Company's
stockholders' equity, less intangible assets, divided by 266,553,585 shares of
Common Stock outstanding on June 30, 1997, after giving effect to the conversion
of the outstanding shares of Nextel's Non-Voting Common Stock, the Class A
Preferred Stock and the Class B Preferred Stock.

     For purposes hereof, net tangible book value dilution per share represents
the difference between (i) $24.25, the weighted average exercise price of the
Warrants, and (ii) the net tangible book value per share of Common Stock as of
June 30, 1997. After giving effect to the net proceeds to be received by the
Company upon exercise of the Warrants (assuming exercise of all of the Warrants
and taking into account the expenses to the Company), the net tangible book
value per share of the Company as of June 30, 1997 would have been $(6.00). The
following table illustrates this pro forma per share dilution.

  relates.
 
ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Set forth below is a description of certain provisions of the Restated
Certificate of Incorporation, (the "Nextel Charter"), of Nextel Communications,
Inc. ("New Nextel," and, together with "Old Nextel," its predecessor corporation
of the same name, "Nextel"), the Amended and Restated By-laws of Nextel (the
"Nextel By-laws") and the Delaware General Corporation Law (the "DGCL"). This
description is intended as a summary only and is qualified in its entirety by
reference to the Nextel Charter, the Nextel By-laws and the DGCL.
 
     Elimination of Liability in Certain Circumstances.  The Nextel Charter
provides that, to the full extent provided by law, a director will not be
personally liable to Nextel or its stockholders for or with respect to any acts
or omissions in the performance of his or her duties as a director. The DGCL
provides that a corporation may limit or eliminate a director's personal
liability for monetary damages to the corporation or its stockholders, except
for liability (i) for any breach of the director's duty of loyalty to such
corporation or its stockholders, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii) for
paying a dividend or approving a stock repurchase in violation of Section 174 of
the DGCL or (iv) for any transaction from which the director derived an improper
personal benefit.
 
     While Article 7 of the Nextel Charter provides directors with protection
from awards for monetary damages for breaches of the duty of care, it does not
eliminate the directors' duty of care. Accordingly, Article 7 will have no
effect on the availability of equitable remedies such as an injunction or
rescission based on a director's breach of the duty of care. The provisions of
Article 7 as described above apply to officers of Nextel only if they are
directors of Nextel and are acting in their capacity as directors, and does not
apply to officers of Nextel who are not directors.
 
     Indemnification and Insurance.  Under the DGCL, directors and officers as
well as other employees and individuals may be indemnified against expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement in
connection with specified actions, suits or proceedings, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of the corporation as a derivative action) if they acted in good faith and
in a manner they reasonably believed to be in or not opposed to the best
interest of the corporation and, with respect to any criminal action or
proceeding, had no reasonable cause to believe their conduct was unlawful.
 
     Article 6 of the Nextel Charter and Article VII of the Nextel By-laws
provide to directors and officers indemnification to the full extent provided by
law, thereby affording the directors and officers of Nextel the protections
available to directors and officers of Delaware corporations. Article VII of the
Nextel By-laws also provides that expenses incurred by a person in defending a
civil or criminal action, suit or proceeding by reason
 
                                      II-1
<PAGE>   34
 
of the fact that he or she is or was a director or officer shall be paid in
advance of the final disposition of such action, suit or proceeding upon receipt
of an undertaking by or on behalf of such director or officer to repay such
amount if it shall ultimately be determined that he or she is not entitled to be
indemnified by Nextel as authorized by relevant Delaware law. Nextel has
obtained directors and officers liability insurance providing coverage to its
directors and officers.
 
     On September 12, 1991, the Board of Directors of Nextel unanimously adopted
resolutions authorizing Nextel to enter into an Indemnification Agreement (the
"Indemnification Agreement") with each director of Nextel. Nextel has entered
into an Indemnification Agreement with each of its directors and officers.
 
     One of the purposes of the Indemnification Agreements is to attempt to
specify the extent to which persons entitled to indemnification thereunder (the
"Indemnitees") may receive indemnification under circumstances in which
indemnity would not otherwise be provided by the DGCL. Pursuant to the
Indemnification Agreements, an Indemnitee is entitled to indemnification as
provided by Section 145 of the DGCL and to indemnification for any amount which
the Indemnitee is or becomes legally obligated to pay relating to or arising out
of any claim made against such person because of any act, failure to act or
neglect or breach of duty, including any actual or alleged error, misstatement
or misleading statement, which such person commits, suffers, permits or
acquiesces in while acting in the Indemnitee's position with Nextel. The
Indemnification Agreements are in addition to and are not intended to limit any
rights of indemnification which are available under the Nextel Charter or the
Nextel By-laws, any policy of insurance or otherwise. Nextel is not required
under the Indemnification Agreements to make payments in excess of those
expressly provided for in the DGCL in connection with any claim against the
Indemnitee:
 
          (i) which results in a final, nonappealable order directing the
     Indemnitee to pay a fine or similar governmental imposition which Nextel is
     prohibited by applicable law from paying; or
 
          (ii) based upon or attributable to the Indemnitee gaining in fact a
     personal profit to which he was not legally entitled including, without
     limitation, profits made from the purchase and sale by the Indemnitee of
     equity securities of Nextel which are recoverable by Nextel pursuant to
     Section 16(b) of the Securities Exchange Act of 1934, as amended (the
     "Exchange Act") and profits arising from transactions in publicly traded
     securities of Nextel which were effected by the Indemnitee in violation of
     Section 10(b) of the Exchange Act or Rule 10b-5 promulgated thereunder.
 
     In addition to the rights to indemnification specified therein, the
Indemnification Agreements are intended to increase the certainty of receipt by
the Indemnitee of the benefits to which he or she is entitled by providing
specific procedures relating to indemnification.
 
     The Indemnification Agreements are also intended to provide increased
assurance of indemnification by prohibiting Nextel from adopting any amendment
to the Nextel Charter or the Nextel By-laws which would have the effect of
denying, diminishing or encumbering the Indemnitee's rights pursuant thereto or
to the DGCL or any other law as applied to any act or failure to act occurring
in whole or in part prior to the effective date of such amendment.
 
ITEM 16.  EXHIBITS.
 
     Pursuant to Item 601 of Regulation S-K, 17 C.F.R.
sec. 229.601(b)(4)(iii)(A), Nextel has excluded from Exhibit No. 4 instruments
defining the rights of holders of long-term debt with respect to debt that does
not exceed 10% of the total assets of Nextel. Nextel agrees to furnish copies of
such instruments to the Commission upon request.

ITEM 17.  UNDERTAKINGS.
 
     The undersigned registrant hereby undertakes:
 
          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement:
 
             (i) To include any prospectus required by Section 10(a)(3) of the
        Securities Act of 1933;
 
             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) if, in the aggregate, the
        changes in volume and price represent no more than a 20% change in the
        maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement; and
 
             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the registration statement
        or any material change to such information in the registration
        statement;
 
provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
registration statement is on Form S-3 or Form S-8, and the information required
to be included in a post-effective amendment by those paragraphs is contained in
periodic reports filed with or furnished to the Commission by the registrant
pursuant to Sections 13 or 15(d) of the Securities Exchange Act of 1934 that are
incorporated by reference in the registration statement.
 
          (2) That, for the purpose 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) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.
 
          (4) That, for purposes of determining any liability under the
     Securities Act of 1933, each filing of the registrant's annual report
     pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934
     (and, where applicable, each filing of an employee benefit plan's annual
     report pursuant to Section 15(d) of the Securities Exchange Act of 1934)
     that is incorporated by reference in the registration statement 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.
 
          (5) 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 for 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 Securities Act and will be governed by the final adjudication of such
     issue.

     Pursuant to the requirements of the Securities Act of 1933, the registrant
certifies that is has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-3 and has duly caused this post-effective
amendment to its registration statement to be signed on its behalf by the
