     Nextel Communications, Inc., a Delaware corporation ("Nextel" or the
"Company"), hereby offers, upon the terms and subject to the conditions set
forth in this Prospectus and in the accompanying Letter of Transmittal (the
"Letter of Transmittal"), to exchange (the "Exchange Offer") its 9.75% Senior
Serial Redeemable Discount Notes due 2007 (the "Exchange Senior Notes"), which
have been registered under the Securities Act of 1933, as amended (the
"Securities Act"), for an equal principal amount at maturity of its outstanding
9.75% Senior Serial Redeemable Discount Notes due 2007 (the "Private Notes"), of
which $1,129,100,000 in principal amount at maturity was issued on October 22,
1997 and is outstanding on the date hereof. See "The Exchange Offer." The form
and terms of the Exchange Senior Notes are identical in all material respects to
those of the Private Notes, except for certain transfer restrictions and
registration rights relating to the Private Notes and except for certain
interest provisions related to such registration rights. The Exchange Senior
Notes will evidence the same indebtedness as the Private Notes (which they
replace) and will be entitled to the benefits of an Indenture dated as of
October 22, 1997, governing the Private Notes and the Exchange Senior Notes (the
"Indenture"). The Exchange Senior Notes and the Private Notes are sometimes
referred to collectively as the "Notes."
 
     The Exchange Senior Notes will mature on October 31, 2007. Cash interest
will not accrue on the Exchange Senior Notes prior to October 31, 2002 and will
be payable on April 30 and October 31 of each year, commencing April 30, 2003,
at a rate of 9.75% per annum. See "Description of Exchange Senior Notes" and
"Certain United States Federal Income Tax Considerations." The Exchange Senior
Notes will be redeemable, at the option of the Company at any time, in whole or
in part, on or after October 31, 2002, at the redemption prices set forth
herein, plus accrued and unpaid interest, if any, to the date of redemption. See
"Description of Exchange Senior Notes -- Optional Redemption." In addition, in
the event of one or more sales by the Company prior to October 31, 2000 of at
least $125,000,000 of its Capital Stock (as defined in "Description of Exchange
Senior Notes -- Certain Definitions"), up to a maximum of 33 1/3% of the
aggregate Accreted Value (as defined in "Description of Exchange Senior
Notes -- Certain Definitions") of outstanding Exchange Senior Notes may be
redeemed at the Company's option within 180 days after such sale from the net
cash proceeds thereof at 109.75% of such Accreted Value to the date of
redemption. Upon a Change of Control (as defined in "Description of Exchange
Senior Notes -- Certain Definitions"), the Company will be required to make an
offer to purchase the Exchange Senior Notes at 101% of the Accreted Value
thereof, or, in the case of any such repurchase on or after October 31, 2002,
101% of the principal amount thereof, plus accrued and unpaid interest, if any,
to the date of repurchase. There can be no assurance that the Company will have
the financial resources necessary to repurchase the Exchange Senior Notes upon a
Change of Control.

     SEE "RISK FACTORS" COMMENCING ON PAGE 17 FOR CERTAIN INFORMATION THAT
SHOULD BE CONSIDERED IN CONNECTION WITH THE EXCHANGE OFFER.
 
  THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
 EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
   AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
                               CRIMINAL OFFENSE.
 
                            ------------------------
 
                     This Prospectus is dated        , 1997
<PAGE>   3
 
     The Exchange Senior Notes will be senior unsecured indebtedness of the
Company, will rank pari passu in right of payment with all unsubordinated,
unsecured indebtedness of the Company, and will be senior in right of payment to
all subordinated indebtedness of the Company. As of September 30, 1997, after
giving pro forma effect to certain transactions described herein, the Company
would have had approximately $2,726,907,000 of indebtedness outstanding
(excluding (i) indebtedness evidenced by the Private Notes, (ii) guaranties of
subsidiary indebtedness of $970,741,000 (such guaranty obligations would rank
pari passu in right of payment with the Exchange Senior Notes but the underlying
guaranteed indebtedness is assumed to be satisfied from the assets of the
primary obligors), and (iii) trade payables and other accrued liabilities) that
ranks pari passu in right of payment with the Exchange Senior Notes. The Company
is a holding company that conducts substantially all of its business through
subsidiaries. The Exchange Senior Notes will be obligations of the Company only,
and its operating subsidiaries will have no obligation to pay amounts due
pursuant to the Exchange Senior Notes. The Exchange Senior Notes will be
effectively subordinated to all liabilities of the Company's subsidiaries,
including trade payables and other accrued liabilities. As of September 30,
1997, after giving pro forma effect to certain transactions described herein,
the Company's subsidiaries would have had approximately $1,502,858,000 of
indebtedness outstanding, excluding trade payables and other accrued
liabilities. The Company and its subsidiaries are expected to incur substantial
additional indebtedness in the next several years. See "Risk Factors -- Risk
Factors Relating to Nextel -- Nextel to Require Additional Financing," "The
Exchange Offer," and "Description of Exchange Senior Notes."
 
     The Company will accept for exchange any and all Private Notes that are
properly tendered in the Exchange Offer and not withdrawn prior to 5:00 p.m.,
New York City time, on               , 1998, (such date if and as it may be
extended, the "Expiration Date"). Tenders of Private Notes may be withdrawn at
any time prior to 5:00 p.m., New York City time, on the Expiration Date. In the
event the Exchange Offer is terminated, the Private Notes not accepted for
exchange will be returned without expense to the tendering holders as promptly
as practicable. See "The Exchange Offer."
 
     Based on a previous interpretation by the staff of the Securities and
Exchange Commission (the "Commission") set forth in no-action letters to third
parties, including "Exxon Capital Holdings Corporation" (available May 13,
1988), "Morgan Stanley & Co. Incorporated" (available June 5, 1991) (the "Morgan
Stanley Letter"), "Mary Kay Cosmetics, Inc." (available June 5, 1991), "Warnaco,
Inc." (available October 11, 1991), and "K-III Communications Corp." (available
May 14, 1993), the Company believes that the Exchange Senior Notes issued
pursuant to the Exchange Offer in exchange for the Private Notes may be offered
for resale, resold, and otherwise transferred by a holder thereof (other than
(i) a broker-dealer who purchased such Exchange Senior Notes directly from the
Company or (ii) a person that is an affiliate of the Company (within the meaning
of Rule 405 under the Securities Act)), without compliance with the registration
and prospectus delivery requirements of the Securities Act; provided, that the
holder is acquiring Exchange Senior Notes in the ordinary course of its business
and is not participating, does not intend to participate, and has no arrangement
or understanding with any person to participate, in the distribution of the
Exchange Senior Notes. Holders of Private Notes wishing to accept the Exchange
Offer must represent to the Company that such conditions have been met. Holders
of Private Notes who tender their Private Notes in the Exchange Offer with the
intention to participate in a distribution of the Exchange Senior Notes may not
rely upon the Morgan Stanley Letter or other similar letters.
 
     Each broker-dealer that receives Exchange Senior Notes for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Senior Notes. The
Letter of Transmittal states that by so acknowledging and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act, in connection with such
resales of Exchange Senior Notes received in exchange for Private Notes where
such Private Notes were acquired by such broker-dealer as a result of
market-making activities or other trading activities. Nextel has agreed, subject
to certain conditions, that, for a period of 90 days after the Expiration Date,
it will make this Prospectus available to any broker-dealer for use in
connection with any such resale. See "The Exchange Offer -- Resale of the
Exchange Senior Notes" and "Plan of Distribution."
 
     Nextel believes that none of the registered holders of the Private Notes is
an affiliate (as such term is defined in Rule 405 under the Securities Act) of
Nextel. Prior to this Exchange Offer, there has been no public market for the
Private Notes. The Private Notes have traded on the Private Offerings, Resales
and Trading through Automated Linkages ("PORTAL") market. Nextel does not intend
to list the Exchange Senior Notes on any securities exchange. There can be no
assurance that an active market for the Exchange Senior Notes will develop. To
the extent that a market for the Exchange Senior Notes does develop, the market
value of the Exchange Senior Notes will depend on market conditions
<PAGE>   4
 
(including yields on alternative investments), general economic conditions,
Nextel's financial condition and other conditions. Such conditions may cause the
Exchange Senior Notes, to the extent actively traded, to trade at a significant
discount from their accreted value. Nextel has not entered into any arrangement
or understanding with any person to distribute the Exchange Senior Notes to be
received in the Exchange Offer.
 
     Holders of Private Notes whose Private Notes are not tendered and accepted
in the Exchange Offer will continue to hold such Private Notes and will be
entitled to all the rights and preferences and subject to the limitations
applicable thereto under the Indenture. Following consummation of the Exchange
Offer, the holders of Private Notes will continue to be subject to the existing
restrictions upon transfer thereof, and the Company will have no further
obligation to such holders to provide for the registration under the Securities
Act of the Private Notes held by them.
 
     The Company will not receive any proceeds from, and has agreed to bear all
registration expenses of, the Exchange Offer. No underwriter is being used in
connection with the Exchange Offer. See "The Exchange Offer -- Resale of the
Exchange Senior Notes."

                                  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 remaining 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
 
                                        1
<PAGE>   9
 
September 30, 1997, Nextel's Digital Mobile networks were operating in major
metropolitan market areas throughout the United States in which approximately
60% of the total United States population lives or works.
 
     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 -- Risk
Factors Relating to Nextel -- 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 approximately 60% 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, Salt Lake
City/ Provo, Phoenix, Tucson, Spokane, Cincinnati, Dayton, San Antonio, and
Austin. Based on its current plans and construction schedules, by the end of
1998, 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.
 
     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
946,600 at September 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 significantly expanded its business activities
to include operations and investments involving wireless communications service
providers outside of the United States that 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 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 revised business plan that 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) in its domestic markets during 1997 and 1998. Nextel has
estimated that system
 
                                        2
<PAGE>   10
 
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 $1.45 billion. Such estimate is based on a significant number
of assumptions and may be increased in connection with Nextel's development of
its capital and operating budgets for 1998 based, in part, on Nextel's
experience in 1997, including its rapid subscriber growth and increased demand
for its services. Nextel currently expects that the 1998 budgeting process will
not be finalized until late December 1997 or early 1998. See "Risk
Factors -- Risk Factors Relating to Nextel -- Nextel to Require Additional
Financing." Nextel believes that the implementation of the accelerated build-out
contemplated by its business plan will 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. Furthermore, Nextel believes that, assuming
the Company successfully concludes its nationwide Digital Mobile network
build-out plan and develops a sufficient customer base in its markets, 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
that may encounter significant financial and other challenges in replicating or
overtaking Nextel's industry position. 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 defined
herein) 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 -- Risk Factors Relating to
Nextel -- Nextel to Require Additional Financing" and "-- Forward Looking
Statements."
 
RECENT DEVELOPMENTS
 
     PCI Merger.  Nextel entered into an Agreement of Merger and Plan of
Reorganization dated as of October 2, 1996, as amended, with Pittencrieff
Communications, Inc. ("PCI") providing for the merger of PCI with a wholly-owned
indirect subsidiary of Nextel. PCI has approximately 6,000 800 MHz SMR channels
covering a total population of over 27 million people, predominantly in the
states of Texas, Oklahoma, New Mexico, and Arizona. The closing of such merger
transaction occurred on November 12, 1997, resulting in the issuance (or
reservation for issuance) of approximately 6,235,000 shares of Common Stock.
 
     Private Notes Issuance.  On October 22, 1997, Nextel completed the sale of
$1,129,100,000 principal amount at maturity of the Private Notes. Nextel
received approximately $682,000,000 in net cash proceeds from the sale of the
Private Notes (the "Private Notes Proceeds"). Such proceeds may be used for
general corporate purposes, including either to refinance a portion of the
indebtedness outstanding under the Old Senior Notes (as defined herein) (which
the Company may effect through repurchases, by way of a tender offer, open
market or privately negotiated purchases, redemption of the Old Senior Notes
pursuant to their terms, or any combination thereof) or to refinance a portion
of the cost of implementing its business plan that otherwise would have been
funded by borrowings pursuant to the Bank Credit Facility, the Vendor Credit
Facility, and/or the Second Vendor Financing Agreement (each as defined herein).
 
     The terms of the Notes are set forth in the Indenture which has been filed
with the Commission and is incorporated by reference herein. The Indenture and
the September Indenture are referred to collectively as the "New Indentures."
 
     September Notes Issuance.  On September 17, 1997, Nextel completed the sale
of $840,000,000 in principal amount at maturity of its 10.65% Senior Redeemable
Discount Notes due September 15, 2007 (such securities issued originally and any
securities issued in exchange therefor in the September Notes Exchange Offer (as
defined herein) collectively, the "September Notes" and together with the Notes,
the "New Senior Notes"). Nextel received approximately $486,000,000 in net cash
proceeds from the sale of the September Notes (the "September Notes Proceeds").
Such proceeds were principally used to repay a portion of the
 
                                        3
<PAGE>   11
 
outstanding borrowings under the Bank and Vendor Credit Facilities (as defined
herein) with the remaining proceeds available for general corporate purposes.
 
     Cash interest will not accrue on the September Notes prior to September 15,
2002 and will be payable on March 15 and September 15 of each year, commencing
March 15, 2003, at a rate of 10.65% per annum. The September 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 September Notes not to exceed a maximum of 33 1/3% of the aggregate accreted
value of the outstanding September Notes may be redeemed at Nextel's option
within 180 days after such sale from the net cash proceeds thereof at 109.75% of
such accreted value on the date of redemption. The September 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 Senior Notes (as defined herein) and the September Notes,
and will be senior in right of payment to all subordinated indebtedness of
Nextel.
 
     The September Notes were initially issued in a private placement
transaction that was not registered with the Commission under the Securities
Act. On December 8, 1997, the Commission declared effective Nextel's
registration statement with respect to a registered offer to exchange the then
outstanding September Notes for an equal principal amount at maturity of 10.65%
Senior Redeemable Discount Notes due September 15, 2007 that have been
registered pursuant to the Securities Act (the "September Notes Exchange
Offer"). In the event that the September Notes Exchange Offer is not consummated
prior to specified dates, additional incremental interest on the accreted value
of the September Notes will accrue until the September Notes Exchange Offer is
consummated or certain other requirements are met.
 
     The terms of the September Notes are set forth in the related indenture
(the "September 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 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 (together, the "Bank and
Vendor Credit Facilities") 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 the Vendor Credit Facility.
 
     Giving effect to these amendments and to the agreement relating to Second
Secured Borrowings (the "Second Vendor Financing Agreement"), 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 $1,085,000,000
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 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. The indebtedness incurred upon issuance
of the Private Notes may, under certain circumstances
 
                                        4
<PAGE>   12
 
described elsewhere herein, limit the Company's ability to incur indebtedness
otherwise available for incurrence pursuant to the Bank Credit Facility, the
Vendor Credit Facility, and/or the Second Vendor Financing Agreement. See "Risk
Factors -- Risk Factors Relating to Nextel -- Nextel to Require Additional
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.
 
     Issuance of Series D Preferred Stock.  On July 21, 1997, Nextel completed
the sale of 500,000 shares of its 13% Series D Exchangeable Preferred Stock (the
shares of such stock so issued originally, any shares of such stock issued in
exchange therefor in the Preferred Stock Exchange Offer (as defined herein) and
any shares of such stock issued as payment in kind dividends thereon,
collectively, 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. Nextel elected to
pay the first quarterly dividend on the Series D Preferred Stock in kind,
resulting in the issuance of an additional 15,167 shares of Series D Preferred
Stock on October 15, 1997. 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 initially issued in a private
placement transaction that was not registered with the Commission under the
Securities Act. On November 12, 1997, the Commission declared effective Nextel's
registration statement with respect to a registered offer to exchange the then
outstanding shares of Series D Preferred Stock for an equal number of shares of
13% Series D Exchangeable Preferred Stock that have been 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
(which is not currently expected), 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 related
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
 
                                        5
<PAGE>   13
 
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 Indentures as the
"Nextel Indentures." The Old Senior Notes are referred to collectively with the
New Senior Notes as the "Nextel Notes." 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 proceeds of new equity issuances include the Preferred
Stock Proceeds, but would exclude equity funds from several identified sources,
including most significantly equity investment proceeds received from affiliates
of Craig O. McCaw ("Mr. McCaw") in connection with the exercise of the First
Option (as defined herein) and also the Subscription Proceeds (as defined
herein) received by Nextel), 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 -- Risk Factors Related
to Nextel -- 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
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
totaling 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.
Approximately 3,945,000 of the offered shares of Common Stock were subscribed
for by Consenting Holders for an aggregate purchase price of approximately
$63,700,000 (the "Subscription Proceeds").
 
     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 -- Risk Factors Relating to
Nextel -- 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 Mr. 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, at any time through July 28, 1998, 25,000,000 shares of Common
Stock (the "New Option"), 15,000,000 shares of which are purchasable at an
exercise price of $16.00 per share and the remaining 10,000,000 shares of which
 
                                        6

are purchasable at an exercise price of $18.00 per share. 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 transferee (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
Mr. 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, that 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.

THE EXCHANGE OFFER.........  The Company is offering, upon the terms and
                             conditions set forth herein and in the Letter of
                             Transmittal, to exchange Exchange Senior Notes for
                             an equal principal amount at maturity of Private
                             Notes that are properly tendered and accepted in
                             the Exchange Offer. The Company will issue
                             Exchange Senior Notes on or as promptly as
                             practicable after the Expiration Date. As of the
                             date hereof, $1,129,100,000 in principal amount at
                             maturity of Private Notes is outstanding. See "The
                             Exchange Offer."
 
RESALE OF EXCHANGE SENIOR
  NOTES....................  Based on an interpretation by the staff of the
                             Commission set forth in no-action letters issued to
                             third parties, including "Exxon Capital Holdings
                             Corporation" (available May 13, 1988), the Morgan
                             Stanley Letter, "Mary Kay Cosmetics, Inc."
                             (available June 5, 1991), "Warnaco, Inc."
                             (available October 11, 1991), and "K-III
                             Communications Corp." (available May 14, 1993), the
                             Company believes that Exchange Senior Notes issued
                             pursuant to the Exchange Offer in exchange for
                             Private Notes may be offered for resale, resold, or
                             otherwise transferred by any holder thereof (other
                             than any such holder that is an "affiliate" of the
                             Company within the meaning of Rule 405 under the
                             Securities Act) without compliance with the
                             registration and prospectus delivery provisions of
                             the Securities Act, provided that such Exchange
                             Senior Notes are acquired in the ordinary course of
                             such holder's business and that such holder has no
                             arrangement or understanding with any person to
                             participate in the distribution of such Exchange
                             Senior Notes. Holders of Private Notes who tender
                             their Private Notes in the Exchange Offer with the
                             intention to participate in a distribution of the
                             Exchange Senior Notes may not rely upon the Morgan
                             Stanley Letter or other similar letters. In the
                             event that the Company's belief is inaccurate,
                             holders of Exchange Senior Notes who transfer
                             Exchange Senior Notes in violation of the
                             prospectus delivery provisions of the Securities
                             Act and without an exemption from registration
                             thereunder may incur liability thereunder. The
                             Company does not assume or indemnify holders
                             against such liability. The Exchange Offer is not
                             being made to, nor will Nextel accept surrenders
                             for exchange from, holders of Private Notes (i) in
                             any jurisdiction in which the Exchange Offer or the
                             acceptance thereof would not be in compliance with
                             the securities or blue sky laws of such
                             jurisdiction or (ii) if any holder is engaged or
                             intends to engage in a distribution of the Exchange
                             Senior Notes. Each broker-dealer that receives
                             Exchange Senior Notes for its own account in
                             exchange for Private Notes, where such Private
                             Notes were acquired by such broker-dealer as a
                             result of market-making activities or other trading
                             activities, must, among other things, acknowledge
                             that it will deliver a prospectus in connection
                             with any resale of such Exchange Senior Notes. The
                             Company has not entered into any arrangement or
                             understanding with any person to distribute the
                             Exchange Senior Notes to be received in the
                             Exchange Offer. See "The Exchange Offer -- Resale
                             of the Exchange Senior Notes" and "Plan of

                             consummation of the Exchange Offer except with
                             respect to the Company's duty to keep the
                             Registration Statement effective until closing of
                             the Exchange Offer and, subject to certain
                             conditions, for a period not to exceed 90 days
                             after the Expiration Date, to provide copies of the

                             acquired for its own account as a result of
                             market-making or other trading activities. See "The

                             its sole discretion, in which case the term

CONDITIONS TO THE EXCHANGE
  OFFER....................  The Company may terminate the Exchange Offer if it
                             determines that its ability to proceed with the
                             Exchange Offer would be materially impaired due to
                             any legal or governmental action, any new law,
                             statute, rule or regulation, any interpretation by
                             the staff of the Commission of any existing law,
                             statute, rule or regulation, or the failure to
                             obtain any necessary approvals of governmental
                             agencies or holders of Private Notes. The Company
                             does not expect any of the foregoing conditions to
                             occur, although there can be no assurance that such
                             conditions will not occur. See "The Exchange
                             Offer -- Conditions."

                             Exchange Offer must complete, sign, and date the
                             Letter of Transmittal, or a facsimile thereof, in

                             of Transmittal, the holder will represent to and
                             agree with the Company that, among other things,
                             (i) the Exchange Senior Notes to be acquired by
                             such holder of Private Notes in connection with the

                             participate and has no arrangement or understanding
                             with any person to participate in a distribution of
                             the Exchange Senior Notes, and (iii) such holder is
                             not an "affiliate," as defined in Rule 405 under

                             is a broker-dealer that will receive Exchange
                             Senior Notes for its own account in exchange for
                             Private Notes that were acquired as a result of
                             market-making or other trading activities, such

<PAGE>   17
 
                             holder will be required to acknowledge in the
                             Letter of Transmittal that such holder will deliver
                             a prospectus in connection with any resale of such
                             Exchange Senior Notes, however, by so acknowledging
                             and by delivering a prospectus, such holder will
                             not be deemed to admit that it is an "underwriter"
                             within the meaning of the Securities Act. See "The
                             Exchange Offer -- Procedures for Tendering."
 
SPECIAL PROCEDURES FOR
BENEFICIAL OWNERS..........  Any beneficial owner whose Private Notes are
                             registered in the name of a broker, dealer,
                             commercial bank, trust company or other nominee and
                             who wishes to tender such Private Notes in the
                             Exchange Offer should contact such registered
                             holder promptly and instruct such registered holder
                             to tender on such beneficial owner's behalf. If
                             such beneficial owner wishes to tender on such
                             owner's own behalf, such owner must, prior to
                             completing and executing the Letter of Transmittal
                             and delivering such owner's Private Notes, either
                             make appropriate arrangements to register ownership
                             of the Private Notes in such owner's name or obtain
                             a properly completed bond power from the registered
                             holder. The transfer of registered ownership may
                             take considerable time and may not be able to be
                             completed prior to the Expiration Date. See "The
                             Exchange Offer -- Procedures for Tendering."

RANKING....................  The Exchange Senior Notes will be senior unsecured
                             indebtedness of the Company, will rank pari passu
                             in right of payment with all unsubordinated,
                             unsecured indebtedness of the Company, and will be
                             senior in right of payment to all subordinated
                             indebtedness of the Company. As of September 30,
                             1997, after giving pro forma effect to certain
                             transactions described herein, the Company would
                             have had approximately $2,726,907,000 of
                             indebtedness outstanding (excluding (i)
                             indebtedness evidenced by the Private Notes, (ii)
                             guaranties of subsidiary indebtedness of
                             $970,741,000 (such guaranty obligations would rank
                             pari passu in right of payment with the Notes but
                             the underlying guaranteed indebtedness is assumed
                             to be satisfied from the assets of the primary
                             obligors), and (iii) trade payables and other
                             accrued liabilities) that ranks pari passu in right
                             of payment with the Exchange Senior Notes. The
                             Company is a holding company that conducts
                             substantially all of its business through
                             subsidiaries. The Notes will be obligations of the
                             Company only, and its operating subsidiaries will
                             have no obligation to pay amounts due pursuant to
                             the Notes. The Notes will be effectively
                             subordinated to all liabilities of the Company's
                             subsidiaries, including trade payables and other
                             accrued liabilities. As of September 30, 1997,
                             after giving pro forma effect to certain
                             transactions described herein, the Company's
                             subsidiaries would have had approxi-

                             mately $1,502,858,000 of indebtedness outstanding,
                             excluding trade payables and other accrued
                             liabilities. The Company and its subsidiaries are
                             expected to incur substantial additional
                             indebtedness in the next several years. See "Risk
                             Factors -- Risk Factors Related to Exchange Senior
                             Notes and Exchange Offer -- Dependence of Company
                             on Subsidiaries for Cash to Pay Interest on and for
                             Repayment of Notes," "-- Effect of Holding Company
                             Structure," "-- Effect of Substantial Existing and
                             Additional Indebtedness; Refinancing Risk" and
                             "Description of Exchange Senior Notes -- Certain
                             Covenants -- Limitation on Consolidated Debt."
 
ORIGINAL ISSUE DISCOUNT....  The Private Notes were issued with original issue
                             discount for United States Federal income tax
                             purposes. The Exchange Senior Notes should be
                             treated as a continuation of the Private Notes.
                             Consequently, holders of Exchange Senior Notes
                             generally will be required to include amounts in
                             advance of receipt of the cash payments to which
                             the income is attributable for United States
                             Federal income tax purposes. See "Certain United
                             States Federal Income Tax
                             Considerations -- Original Issue Discount."
 
CERTAIN COVENANTS..........  The Indenture contains certain covenants for the
                             benefit of the holders of the Notes which, among
                             other things, restrict the ability of the Company
                             and each Restricted Subsidiary (as defined in
                             "Description of Exchange Senior Notes -- Certain
                             Definitions") to: incur additional indebtedness;
                             pay dividends or make distributions in respect of
                             the Company's Capital Stock other than dividend,
                             penalty or other mandated payments on or in respect
                             of any class or series of the Company's currently
                             authorized and designated preferred stock; redeem,
                             repurchase, or make payments on any subordinated
                             Debt (as defined in "Description of Exchange Senior
                             Notes -- Certain Definitions") of the Company prior
                             to its scheduled maturity, repayment or sinking
                             fund payment, as applicable; make investments or
                             certain other restricted payments; enter into
                             transactions with affiliates; engage in any
                             business other than the telecommunications business
                             and related activities and services; or effect a
                             merger or consolidation or sale of all or
                             substantially all of its assets. Also, the Company
                             must provide certain annual and quarterly financial
                             information reports to the Trustee, to holders of
                             the Notes, and to the Commission. These limitations
                             will, however, be subject to important
                             qualifications and exceptions. See "Description of
                             Exchange Senior Notes -- Certain Covenants."
 
CHANGE OF CONTROL..........  Upon a Change of Control, the Company will be
                             required to make an offer to purchase the Notes at
                             a purchase price equal to 101% of the Accreted
                             Value thereof, or, in the case of any purchase date
                             on or after October 31, 2002, 101% of the principal
                             amount thereof, plus accrued and unpaid interest,
                             if any, to the date of purchase. There can be no
                             assurance that the Company will have sufficient
                             funds available at the time of any Change of
                             Control to make any required debt repayment
                             (including repurchases of the Notes). See
                             "Description of Exchange Senior Notes -- Change of
                             Control."
 
BOOK-ENTRY, DELIVERY
  AND FORM.................  It is expected that delivery of the Exchange Senior
                             Notes will be made in book-entry form. The Company
                             expects that Exchange Senior Notes exchanged for
                             Private Notes currently represented by a restricted
                             global

                             of Cede & Co., its nominee, will be represented by
                             a global notes certificate and deposited upon
                             issuance with the Depository and registered in its
                             name or the name of its nominee. Beneficial
                             interests in the global notes certificate
                             representing the Exchange Senior Notes will be
                             shown on, and transfers thereof will be effected
                             through, records maintained by the Depository and
                             its participants.
 
     For additional information regarding the Notes, see "Description of the
Exchange Senior Notes" and "Certain United States Federal Income Tax
Considerations."
 
                        NO CASH PROCEEDS TO THE COMPANY
 
     The Company will not receive any proceeds from the issuance of the Exchange
Senior Notes offered hereby. The form and terms of the Exchange Senior Notes are
identical in all material respects to the form and terms of the Private Notes,
except as otherwise described herein under "The Exchange Offer -- Terms of the
Exchange Offer." The Private Notes surrendered in exchange for Exchange Senior
Notes will be retired and canceled and cannot be reissued. Accordingly, issuance
of the Exchange Senior Notes will not result in any increase in the outstanding
indebtedness of the Company.

                                  RISK FACTORS
 
     An investment in the Exchange Senior Notes offered hereby involves a high
degree of risk. The specific factors set forth below, as well as the other
information included and incorporated by reference in this Prospectus, should be
considered when evaluating an investment in the Exchange Senior Notes. See also
"-- Forward Looking Statements."
 
RISK FACTORS RELATING TO NEXTEL
 
  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 $788,607,000 for the nine months ended September 30,
1997. Nextel had an accumulated deficit totaling approximately $1,923,858,000 at
September 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.
 
                                       17
<PAGE>   25
 
     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
have had and may in the future have an 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 and the market
acceptance of TDMA-based technologies, such as iDEN. 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 September 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
 
                                       18
<PAGE>   26
 
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."
 
     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 FCC's 800 MHz
spectrum auction process), debt service 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 September 30, 1997
totaled approximately $563,300,000 (however, approximately $379,600,000 of such
amount represents cash, cash equivalents and marketable securities held by
Nextel International and its subsidiaries, which items are not available to fund
any of the cash needs of Nextel's domestic Digital Mobile and analog SMR
businesses due to restrictions contained in the provisions of the NI Indenture).
 
     The Company is currently implementing its business plan to accelerate and
expand the deployment of its Digital Mobile networks in domestic markets during
1997 and 1998. Nextel has estimated that the external funding required to meet
the cash needs of its domestic business activities during the period from March
31, 1997 through the end of 1998, including principally the funding of
anticipated capital expenditures and potential acquisitions (including potential
acquisitions of licenses in the FCC's 800 MHz spectrum auction) and operating
losses, will be approximately $2,500,000,000, which includes approximately
$1,450,000,000 of system infrastructure and other system capital costs expected
to be incurred during the period. Such estimates were based on a number of
significant assumptions. The Company currently is in the process of developing
its capital and operating budgets for 1998, and as part of such process will be
reviewing a number of such matters in light of its experience with respect to
the Digital Mobile system construction and commercialization efforts during
1997. Nextel currently expects that the 1998 budgeting process will not be
finalized until late December 1997 or early 1998. However, based on the results
of that process to date, the Company anticipates that both its aggregate
domestic business cash needs and its domestic capital expenditure requirements
will be in excess of those previously estimated amounts. Such expected increase
likely will be necessary to accommodate increased system capacity requirements
resulting from the Company's rapid subscriber growth (which exceeded the levels
of assumed growth used in developing the prior estimates) and increased demand
for the Company's wireless services and to make improvements to existing Digital
Mobile system infrastructure to expand and improve systems coverage and
performance to address competitive pressures faced by the Company. Because such
budgeting process is not yet completed, the Company is not currently able to
estimate the extent of the impact that these factors or any other factors may
have on its level of domestic system capital expenditures and/or overall
domestic financing requirements during 1998. See "-- Forward Looking
Statements."
 
     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 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, for an aggregate availability of $2,500,000,000, subject in each
case to the satisfaction or waiver of applicable borrowing conditions. At
September 30, 1997, Nextel had drawn $820,000,000 of its available financing
under the Bank
 
                                       20
<PAGE>   28
 
Credit Facility and had drawn $150,000,000 of its available financing under the
Vendor Credit Facility. Prior to September 30, 1997, Nextel applied the
aggregate of approximately $1,494,800,000 in Preferred Stock Proceeds, September
Notes Proceeds, McCaw Option Proceeds, the portion of the Subscription Proceeds
received to such date, and the proceeds of the Additional Bank Borrowings to
repay a portion of the borrowings outstanding under the Bank and Vendor Credit
Facilities (to the extent the amounts so repaid would be available for future
borrowings thereunder) with the balance of such aggregate net proceeds remaining
available for general corporate purposes. Disregarding any limitations imposed
pursuant to the Old Indentures on the Company's ability to incur debt under the
Bank and Vendor Credit Facilities and/or the Second Vendor Financing Agreement
by reason of the indebtedness incurred upon issuance of the Private Notes, as of
September 30, 1997, a total of $1,530,000,000 (giving effect to the repayment of
all revolving, but no term, loan amounts outstanding under the Bank and Vendor
Credit Facilities) of such $2,500,000,000 in aggregate availability would be
available for future borrowings by the Company. The remaining funds available
for borrowing under the Bank and Vendor Credit Facilities may be drawn upon
prior to the final maturity date 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 also has 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 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 the above-described 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 Vendor Financing Agreement referred to above.
Nextel's receipt of the $482,000,000 in Preferred Stock Proceeds and option and
warrant exercise proceeds in the period from June 1, 1997 (the "Exercise
Proceeds") enabled Nextel to issue the September Notes and still have access to
the full $2,500,000,000 in funding available under the Bank Credit Facility, the
Vendor Credit Facility, and the Second Vendor Financing Agreement under the
limitations on indebtedness contained in the Old Indentures. However, under such
limitations the issuance of the Private Notes will restrict the Company's
ability to access, on approximately a dollar for dollar basis, the amount of
additional funding that would be available under the Bank and Vendor Credit
Facilities and the Second Vendor Financing Agreement unless either (i) the
proceeds from the issuance of the Private Notes are applied to refinance a
portion of the Old Senior Notes in accordance with the Old Indentures (in which
case the indebtedness under the Private Notes, to the extent the proceeds
thereof are applied to effect such refinancing, would constitute "permitted
debt" under the Old Indentures that would not reduce the amounts available under
the Bank and Vendor Credit Facilities or the Second Vendor Financing Agreement)
or (ii) the Company issues additional equity for cash that would support the
incurrence of additional debt under the Old Indentures. In the event the
proceeds from the issuance of the Private Notes are not applied to refinance a
portion of the Old Senior Notes, such proceeds may be utilized to meet the
Company's funding requirements for the implementation of its business plan to
replace a portion of the borrowings available under the Bank and Vendor Credit
Facilities and/or the Second Vendor Financing Agreement, to the extent such
borrowings would be limited by the Old Indentures.
 
     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." Subject to the determination of
the potential impact on financing requirements associated with an increase in
the Company's overall domestic
 
                                       21
<PAGE>   29
 
cash needs, including its domestic capital expenditures as described above, and
assuming (i) 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 (or such funds are replaced with the Private Notes Proceeds
as described above) and (ii) 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 September Notes Proceeds and the Subscription Proceeds), will
provide funds that in the aggregate are expected to be sufficient to implement
the Company's business plan and meet the other currently anticipated 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 800 MHz spectrum auction
process (the first bidding phase of which commenced on October 28, 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, conditions in the telecommunications and/or wireless
communications industry and the feasibility and
 
                                       22
<PAGE>   30
 
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, 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 and limit
the Company's ability to make payments of principal and interest on the Notes,
or to make principal and interest payments on its other indebtedness, including
the amounts from time to time outstanding under the Bank and Vendor Credit
Facilities and the Second Vendor Financing Agreement, and amounts due on or in
respect of any or all of the other Nextel Notes. 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
 
                                       23
<PAGE>   31
 
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 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
September 30, 1997, represented coverage of areas in which approximately 60% 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.
Additionally, certain analog cellular system operators that directly or through
their affiliates also are constructing and operating digital PCS systems, have
announced their intention to make available to their customers dual mode/dual
band (800 MHz cellular/1900 MHz PCS) subscriber units, to combine the enhanced
feature set available on digital PCS systems within their digital service
coverage areas with the broader wireless coverage area available on the analog
cellular network. Nextel does not currently have comparable hybrid subscriber
units available to its customers.
 
     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, nor can there be any assurance that
 
                                       24
<PAGE>   32
 
a sufficient number of customers or potential customers of Nextel's Digital
Mobile systems will be willing to accept system coverage limitations as a
trade-off for the enhanced multi-function wireless communications package
provided by the Company on its nationwide network. 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 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 currently and for the reasonably 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 and increased sales in markets in which Digital Mobile network
services are provided, and, to a limited extent, acquisitions,
 
                                       25
<PAGE>   33
 
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 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 subscriber units and
certain system infrastructure equipment 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 continuing to
take 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 have been experienced as a
result of the increases in subscriber growth and Digital Mobile network wireless
systems and service utilization that have occurred and are currently anticipated
to continue. 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 or anticipated 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
 
                                       26

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. See "-- Forward Looking Statements."
 
  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 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 (i)
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 (ii) 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.
 
                                       27
<PAGE>   35
 
  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 can be no assurance that the value of these assets will be
sufficient to satisfy its obligations. Nextel had a net tangible book value
deficit of approximately $1,829,581,000 as of September 30, 1997.
 
  Nextel Susceptible to Control by Significant Stockholders
 
     Based on securities ownership information relating to Nextel as of
September 30, 1997, giving effect to the November 1997 amended Schedule 13D
filings by Craig O. McCaw and Wendy P. McCaw, 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 15,082,722 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
5,430,803 shares of Common Stock over a six-year period, and (v) a warrant held
by Motorola to purchase 2,890,000 shares of Common Stock, entities controlled by
the McCaw Investor would hold approximately 25.2% and Motorola would hold
approximately 15.6% 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
 
                                       28
<PAGE>   36
 
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 Agreement and 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 (i) the right of any
Motorola-designated Nextel directors to vote in a manner consistent with their
fiduciary duties and (ii) 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 (i) exert effective control over the
approval of amendments to the Certificate of Incorporation, mergers, sales of
assets or other major corporate transactions as well as other matters submitted
for stockholder vote, (ii) defeat a takeover attempt, and (iii) otherwise
control whether particular matters are 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 Corp. ("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."
 
  Commitments to Issue Additional Common Stock May Impair Ability to Raise
Capital
 
     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. Nextel has also granted registration rights with
respect to a significant number of its outstanding shares, including shares of
Common Stock issuable upon conversion of securities issued 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 under the Securities Act. An increase in
the number of shares of Common Stock that
 
                                       29
<PAGE>   37
 
will become available for sale in the public market may adversely affect the
market price of Common Stock and, as a result, could impair Nextel's ability to
raise additional capital through the sale of its equity securities.
 
  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.
 
RISK FACTORS RELATED TO EXCHANGE SENIOR NOTES AND EXCHANGE OFFER
 
  Ability of Nextel to Pay Cash Interest and Other Cash Amounts in Respect of
the Notes
 
     Cash interest will not accrue on the Notes prior to October 31, 2002 and
thereafter will be payable semi-annually on April 30 and October 31 of each
year, commencing April 30, 2003 at a rate of 9.75% per annum. 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 domestic markets, and provisions contained in certain financing
arrangements to which Nextel International and its subsidiaries are parties
operate to restrict transfers of funds between Nextel International and its
subsidiaries and the Company, so that, while such restrictions are in place, any
profits generated by such subsidiaries will not be available to Nextel for,
among other purposes, payment of cash interest on the Notes. There can be no
assurance that Nextel's existing or future financing agreements will permit
Nextel to obtain access to sufficient sums to make cash interest payments when
required on the Notes. In the event that any of Nextel's financing agreements
limit Nextel's ability to pay cash interest on the Notes when required, Nextel
will need to refinance amounts outstanding under such agreements to make such
cash interest payments. There can be no assurance that Nextel will be able to
refinance amounts outstanding under such financing agreements. The failure of
Nextel to pay cash interest on
 
                                       30
<PAGE>   38
 
the Notes when required could result in a Default (as defined herein) under the
Indenture, and also could result in parallel defaults under the other Nextel
Indentures and Nextel's other debt agreements, including the agreements relating
to the Bank and Vendor Credit Facilities and the Second Vendor Financing
Agreement. The successful implementation of Nextel's strategy, including the
accelerated roll out of the Digital Mobile networks, obtaining and retaining a
significant number of subscribers and increasing market share, and achieving
significant and sustained growth in the Company's revenues and earnings from
operations are necessary for the Company to be able to meet the cash interest
and other payment requirements in respect of its indebtedness, including the
Notes. There can be no assurance that the Company will be able to successfully
implement its strategy or that the Company will generate sufficient cash flow to
meet such cash interest and other payment requirements. If sufficient funds to
meet such cash interest and other payment requirements are not generated by the
Company's operations, Nextel may need to seek additional financing or refinance
some or all of its existing or future financing, including the Notes. There can
be no assurance that the Company will be able to obtain such financing or
refinancing on acceptable terms, or at all. See "-- Dependence of Company on
Subsidiaries for Cash to Pay Interest on and for Repayment of Notes" and
"Description of Exchange Senior Notes."
 
  Dependence of Company on Subsidiaries for Cash to Pay Interest on and for
Repayment of the Notes
 
     Because substantially all of the operations of the Company are conducted
through subsidiaries, the Company's cash flow and, consequently, its ability to
pay interest in cash and to service its debt, including the Notes, is dependent
upon the cash flow of its subsidiaries and the payment of funds by those
subsidiaries to Nextel in the form of loans, dividends or otherwise. The
subsidiaries are separate and distinct legal entities and will have no
obligation, contingent or otherwise, to pay any amounts due pursuant to the
terms of the Notes or to make cash available for such purpose. The Bank Credit
Agreement, the Vendor Credit Agreement, and the Second Vendor Financing
Agreement currently impose significant limits on, and are expected to continue
to significantly limit, the amount of cash available to pay dividends or make
loans and cash distributions to Nextel from Nextel's subsidiaries that operate
Digital Mobile networks in Nextel's market areas in the United States.
Similarly, the NI Indenture contains certain restrictive covenants that impose,
and financing arrangements to be entered into by Nextel International and the
entities in which Nextel International holds investments are expected to contain
certain restrictive covenants that impose, restrictions on dividends, loans,
advances, and other payments to Nextel by Nextel International and such
subsidiaries. Accordingly, while such limitations are in place, profits
generated by such subsidiaries may not be available to Nextel (whether in the
form of loans, dividends or otherwise) for, among other purposes, the payment of
cash interest on the Notes or any amounts due pursuant to the terms of the
Notes. The Notes and the Indenture permit the Company and its subsidiaries to
enter into financing arrangements in the future, which may impose restrictions
on dividends, loans, advances, and other payments by those subsidiaries. The
Bank Credit Agreement, the Vendor Credit Agreement, the Second Vendor Financing
Agreement, the Nextel Indentures, and the Certificate of Designation relating to
the Series D Preferred Stock each contain certain restrictive covenants
applicable to the Company and certain of its subsidiaries, such as a limitation
on debt that may be incurred by the Company and its restricted subsidiaries,
that may limit the Company's ability to borrow funds to pay any amounts due
pursuant to the Notes, which may operate to restrict or prohibit the payment of
amounts of cash interest or other amounts that the Company may be required to
pay on the Notes, even if sufficient funds for that purpose otherwise could be
borrowed by the Company. See "-- Effect of Substantial Existing and Additional
Indebtedness; Refinancing Risk."
 
  Effect of Holding Company Structure
 
     Because the Company is a holding company that conducts its business through
its subsidiaries, all existing and future liabilities of the Company's
subsidiaries, including borrowings under the Bank Credit Facility, the Vendor
Credit Facility, and the Second Vendor Financing Agreement, indebtedness
evidenced by the NI Notes and trade payables, will be effectively senior to the
Notes. As of September 30, 1997, the Company's subsidiaries had outstanding
indebtedness and trade payables and other accrued liabilities of approximately
$1,793,577,000. Borrowings under the Bank Credit Facility, the Vendor Credit
Facility, and the Second Vendor Financing Agreement are secured by liens on
assets of Nextel's restricted subsidiaries.
 
                                       31
<PAGE>   39
 
Borrowings by Nextel International or its subsidiaries or affiliates under any
bank or vendor credit facilities that such entities may enter into from time to
time likewise may be secured by liens on assets of Nextel International or of
such subsidiaries and affiliates, and may be guaranteed by such entities as
well. See "-- Risk Factors Relating to Nextel -- Nextel to Require Additional
Financing."
 
     The Notes and the Indenture permit the incurrence of additional
indebtedness by the Company and its subsidiaries. Additional indebtedness of the
Company may rank pari passu with or subordinate to the Notes, while additional
indebtedness of the subsidiaries effectively will rank senior to the Notes. The
Company's subsidiaries will have no obligation to pay amounts due under the
Notes. Earnings generated by any of the Company's subsidiaries, as well as the
existing assets of each such subsidiary, will be used by such subsidiary to
fulfill its own direct debt service requirements, particularly where the
collateral security mechanisms associated with the debt agreements of such
subsidiary may restrict its ability to pay dividends or to make loans, advances
or other distributions to the Company or where the debt of such subsidiary may
be secured by its assets. See "-- Dependence of Company on Subsidiaries for Cash
to Pay Interest on and for Repayment of Notes" and "-- Effect of Substantial
Existing and Additional Indebtedness; Refinancing Risk."
 
  Effect of Substantial Existing and Additional Indebtedness; Refinancing Risk
 
     At September 30, 1997, the Company had approximately $4,242,498,000 of
long-term debt, including current portion, of which approximately $2,725,801,000
is represented by the Old Senior Notes and the September Notes. The Private
Notes, at the date of their issuance, evidenced approximately $699,997,000 in
long term debt. The accretion of original issue discount on the Nextel Notes
will cause an increase in recorded liabilities from September 30, 1997 of
approximately $1,262,462,000. Cash interest payments will commence with respect
to the Old Senior Notes beginning in 1999. The Bank Credit Agreement, the Vendor
Credit Agreement, the Second Vendor Financing Agreement, the Certificate of
Designation relating to the Series D Preferred Stock, and the Nextel Indentures
each limit, but do not prohibit, the incurrence of additional indebtedness by
the Company and certain of its subsidiaries. The Company anticipates that it and
its subsidiaries will incur substantial additional indebtedness in the future in
connection with the construction of its Digital Mobile networks and funding cash
flow deficits, including additional borrowings pursuant to the terms of the Bank
Credit Facility, the Vendor Credit Facility, and the Second Vendor Financing
Agreement.
 
     The level of the Company's and its subsidiaries' indebtedness could have
important consequences to the holders of the Notes, including the following: (i)
the debt service requirements of any additional indebtedness could make it more
difficult for the Company to make payments of cash interest and other amounts on
the Notes; (ii) a substantial portion of the Company's cash flow from
operations, if any, must be dedicated to the payment of principal and interest
on its indebtedness and other obligations, and will not be available for use in
its business; (iii) the level of indebtedness and related cash debt service
needs could limit the Company's flexibility in planning for, or reacting to,
changes in its business; (iv) the Company is expected to be more highly
leveraged than some of its competitors, which may place it at a competitive
disadvantage; and (v) the Company's high degree of indebtedness and related cash
debt service needs will make it more vulnerable in the event of a downturn in
its business.
 
     The Old Senior Notes, the September Notes, the NI Notes, the Bank Credit
Facility, the Vendor Credit Facility, and the Second Secured Borrowings will
mature prior to the maturity of the Notes. In addition, cash interest on the Old
Senior Notes must be paid beginning in 1998, cash dividends on the Series D
Preferred Stock must be paid beginning in 2002 and cash interest on the
September Notes must be paid beginning March 15, 2003. The Company expects that
it may be necessary to refinance the Old Senior Notes, the September Notes, the
NI Notes, the Bank Credit Facility, the Vendor Credit Facility, and the Second
Secured Borrowings at their respective maturities. The Company's ability to
refinance its indebtedness will depend, among other factors, on its financial
condition at the time of the refinancing, the restrictions contained in the
instruments governing its other indebtedness then outstanding, and other factors
beyond the Company's control, including market conditions. There can be no
assurance that the Company will be able to refinance the Old Senior Notes, the
September Notes, the NI Notes, the Bank Credit Facility, the Vendor Credit
Facility, or the Second Secured Borrowings. If the Old Senior Notes, the
September Notes, the NI Notes, the Bank Credit Facility, the Vendor Credit
Facility, or the Second Secured Borrowings cannot be refinanced,
 
                                       32
<PAGE>   40
 
payments required to be made on the Notes may be effectively prohibited, which
in turn may cause a default under the Notes and the Indenture, and under the
Company's other outstanding indebtedness (including the Old Senior Notes, the
September Notes, the Old Indentures, and the September Indenture) and the
Company may not, in such circumstances, be able to meet its obligations on the
Notes or under the Indenture. In addition, the terms of the Indenture do not
prohibit dividends, penalties, or other mandated payments, including mandatory
repurchases, on or of the Company's preferred stock.
 
 Original Issue Discount May Have Unfavorable Tax and Other Legal Consequences
 for Holders of Exchange Senior Notes and the Company
 
     The Private Notes were issued at a substantial discount from their
principal amount at maturity. The Exchange Senior Notes should be treated as a
continuation of the Private Notes. Consequently, holders of the Exchange Senior
Notes should be aware that, although cash interest will not accrue on the
Exchange Senior Notes prior to October 31, 2002, and there will be no periodic
payments of cash interest on the Exchange Senior Notes prior to April 30, 2003,
original issue discount will accrue from the issue date of the Private Notes and
will be includible as interest income periodically (including for periods ending
prior to October 31, 2002) in a holder's gross income for United States Federal
income tax purposes in advance of receipt of the cash payments to which the
income is attributable. See "Certain United States Federal Income Tax
Considerations" for a more detailed discussion of the United States Federal
income tax consequences to the holders of the Exchange Senior Notes regarding
the ownership and disposition of the Exchange Senior Notes.
 
     If a bankruptcy case is commenced by or against Nextel under the United
States Bankruptcy Code after the issuance of the Exchange Senior Notes, the
claim of a holder of Exchange Senior Notes with respect to the principal amount
thereof may be limited to an amount equal to the sum of (i) the initial offering
price and (ii) that portion of the original issue discount which is not deemed
to constitute "unmatured interest" for purposes of the United States Bankruptcy
Code. Any original issue discount that was not amortized as of any such
bankruptcy filing would constitute "unmatured interest."
 
  Absence of Public Market
 
     The Exchange Senior Notes are a new issue of securities for which there is
currently no active trading market. If any such securities are traded after
their initial issuance, they may trade at a discount from their initial offering
price, depending upon the liquidity of such securities, the market for similar
securities, and other factors, including general economic conditions and the
financial condition, performance of, and prospects for the Company. The Private
Notes were sold pursuant to an exemption from registration under applicable
securities laws and are subject to certain transfer restrictions; accordingly,
no public trading market for the Private Notes has developed.
 
  Failure to Exchange Private Notes
 
     The Exchange Senior Notes will be issued in exchange for Private Notes only
after timely receipt by the Exchange Agent of such Private Notes, a properly
completed and duly executed Letter of Transmittal and all other required
documents. Therefore, holders of Private Notes desiring to tender such Private
Notes in exchange for Exchange Senior Notes should allow sufficient time to
ensure timely delivery. Neither the Exchange Agent nor the Company are under any
duty to give notification of defects or irregularities with respect to tenders
of Private Notes for exchange. Private Notes that are not tendered or that are
tendered but not accepted will, following consummation of the Exchange Offer,
continue to be subject to the existing restrictions upon transfer thereof and
will not retain any rights to registration. See "The Exchange Offer --
Consequences of Failure to Exchange." In addition, any holder of Private Notes
who tenders in the Exchange Offer for the purpose of participating in a
distribution of the Exchange Senior Notes will be required to comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any resale transaction. Each broker-dealer who holds Private
Notes acquired for its own account as a result of market-making or other trading
activities and who receives Exchange Senior Notes for its own account in
exchange for such Private Notes pursuant to the Exchange Offer must acknowledge
that it will deliver a prospectus in connection with any resale of such Exchange
Senior Notes. To the extent that Private Notes are
 
                                       33
<PAGE>   41
 
tendered and accepted in the Exchange Offer, the trading market for untendered
and tendered but unaccepted Private Notes could be adversely affected due to the
limited number of Private Notes that are expected to remain outstanding
following the Exchange Offer. See "Plan of Distribution" and "The Exchange
Offer."

     "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,

                               THE EXCHANGE OFFER
 
PURPOSE AND EFFECT OF THE EXCHANGE OFFER
 
     On October 22, 1997, the Company sold $1,129,100,000 in principal amount at
maturity of the Private Notes in a private placement through the Placement
Agents to a limited number of "Qualified Institutional Buyers" and
"Institutional Accredited Investors" (as such terms are defined under the
Securities Act) (collectively, the "Purchasers"). In connection with the sale of
the Private Notes, the Company and the Placement Agents entered into the
Registration Rights Agreement that requires the Company, among other things, to
use its best efforts to file with the Commission a registration statement under
the Securities Act covering the offer by the Company to exchange all of the
Private Notes for the Exchange Senior Notes and to cause such registration
statement to become effective under the Securities Act. The Company is further
obligated, upon the effectiveness of that registration statement, to offer each
Holder of the Private Notes the opportunity to exchange such Private Notes for
an equal principal amount at maturity of Exchange Senior Notes. A copy of the
Registration Rights Agreement has been filed as an exhibit to the Registration
Statement of which this Prospectus is a part. Such Registration Statement has
been filed with the Commission, and the Exchange Offer is being made pursuant to
the Registration Rights Agreement to satisfy the Company's obligations
thereunder. The term "Holder" with respect to the Exchange Offer means any
person in whose name Private Notes are registered on the Company's books or any
other person who has obtained a properly completed assignment from the
registered holder.
 
     In order to participate in the Exchange Offer, a Holder must represent to
the Company, among other things, that (i) the Exchange Senior Notes acquired
pursuant to the Exchange Offer are being obtained in the ordinary course of
business of the person receiving such Exchange Senior Notes, whether or not such
person is the Holder, (ii) neither the Holder nor any such other person is
engaging in or intends to engage in a distribution of such Exchange Senior
Notes, (iii) neither the Holder nor any such other person has an arrangement or
understanding with any person to participate in the distribution of such
Exchange Senior Notes, and (iv) neither the Holder nor any such other person is
an "affiliate" (as defined in Rule 405 of the Securities Act) of the Company. In
exchange for properly tendered Private Notes, the Exchange Senior Notes will be
issued without a restrictive legend and may be reoffered and resold by the
Holder without restrictions or limitations under the Securities Act.
 
RESALE OF THE EXCHANGE SENIOR NOTES
 
     Based on a previous interpretation by the staff of the Commission set forth
in no-action letters issued to third parties, including "Exxon Capital Holdings
Corporation" (available May 13, 1988), the Morgan Stanley Letter, "Mary Kay
Cosmetics, Inc." (available June 5, 1991), "Warnaco, Inc." (available October
11, 1991), and "K-III Communications Corp." (available May 14, 1993), the
Company believes that the Exchange Senior Notes issued pursuant to the Exchange
Offer may be offered for resale, resold, and otherwise transferred by any Holder
of such Exchange Senior Notes (other than any such Holder that is an "affiliate"
of the Company within the meaning of Rule 405 under the Securities Act) without
compliance with the registration and prospectus delivery provisions of the
Securities Act, provided that such Exchange Senior Notes are acquired in the
ordinary course of such Holder's business and such Holder has no arrangement or
understanding with any person to participate in the distribution of such
Exchange Senior Notes. Any Holder who tenders in the Exchange Offer with the
intention of participating in a distribution of the Exchange Senior Notes cannot
rely on such interpretation by the staff of the Commission as set forth in the
Morgan Stanley Letter and other similar letters and must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with a secondary resale transaction. In the event that the Company's
belief regarding resale is inaccurate, Holders of the Exchange Senior Notes who
transfer Exchange Senior Notes in violation of the prospectus delivery
provisions of the Securities Act and without an exemption from registration
thereunder may incur liability thereunder. The Company does not assume or
indemnify Holders against such liability. The Exchange Offer is not being made
to, nor will the Company accept surrenders for exchange from, Holders of Private
Notes in any jurisdiction in which the Exchange Offer or the acceptance thereof
would not be in compliance with the securities or blue sky laws of such
jurisdiction. Each broker-
 
                                       35
<PAGE>   43
 
dealer that receives Exchange Senior Notes for its own account in exchange for
Private Notes, where such Private Notes were acquired by such broker-dealer as a
result of market-making activities or other trading activities ("Participating
Broker-Dealers"), must acknowledge that it will deliver a prospectus in
connection with any resale of such Exchange Senior Notes. In order to facilitate
the disposition of Exchange Senior Notes by Participating Broker-Dealers, the
Company has agreed, subject to certain conditions, to make this Prospectus, as
it may be amended or supplemented from time to time, available for delivery by
Participating Broker-Dealers to satisfy their prospectus delivery obligations
under the Securities Act. The Company is obligated to deal with only one entity
representing Participating Broker-Dealers (the "Representative"), which shall be
Morgan Stanley & Co. Incorporated unless it elects not to act as the
Representative. Accordingly, any Holder that is a Participating Broker-Dealer
must notify the Representative at the telephone number set forth in the Letter
of Transmittal and comply with the procedures for Participating Brokers-Dealers.
Among other things, the Representative is required to confirm with the Company
on a weekly basis that the Prospectus is available. Accordingly, Participating
Broker-Dealers will be required to confirm such availability with the
Representative on a weekly basis. Pursuant to the Registration Rights Agreement,
the Company is not required to amend or supplement the Prospectus for a period
exceeding 90 days after the Expiration Date except in certain circumstances
involving the suspension of the use thereof by the Company. The Company has not
entered into any arrangement or understanding with any person to distribute the
Exchange Senior Notes to be received in the Exchange Offer. See "Plan of
Distribution."
 
TERMS OF THE EXCHANGE OFFER
 
     Upon the terms and subject to the conditions set forth in this Prospectus
and in the Letter of Transmittal, the Company will accept any and all Private
Notes validly tendered and not withdrawn prior to 5:00 p.m., New York City time,
on the Expiration Date.
 
     As of the date of this Prospectus, $1,129,100,000 in principal amount at
maturity of the Private Notes are outstanding. This Prospectus, together with
the Letter of Transmittal, is being sent to all registered Holders of the
Private Notes on the date hereof. There will be no fixed record date for
determining registered holders of the Private Notes entitled to participate in
the Exchange Offer; however, Holders of the Private Notes must tender their
certificates therefor or cause their Private Notes to be tendered by book-entry
transfer prior to the Expiration Date to participate.
 
     The form and terms of the Exchange Senior Notes will be the same as the
form and terms of the Private Notes except that the Exchange Senior Notes will
be registered under the Securities Act and hence will not bear legends
restricting the transfer thereof. Following consummation of the Exchange Offer,
all rights under the Registration Rights Agreement accorded to holders of
Private Notes, including the right to receive additional incremental interest on
the Private Notes to the extent and in the circumstances specified therein, will
terminate.
 
     The Company intends to conduct the Exchange Offer in accordance with the
provisions of the Registration Rights Agreement and the applicable requirements
of the Securities Act and the rules and regulations of the Commission
thereunder. Private Notes that are not tendered for exchange under the Exchange
Offer will remain outstanding and will be entitled to the rights as set forth in
the Indenture. Any Private Notes not tendered for exchange will not retain any
rights under the Registration Rights Agreement and will remain subject to
certain transfer restrictions. See "-- Consequences of Failure to Exchange."
 
     The Company shall be deemed to have accepted validly tendered Private Notes
when, as and if the Company shall have given oral or written notice thereof to
the Exchange Agent. The Exchange Agent will act as agent for the tendering
Holders for the purposes of receiving the Exchange Senior Notes from the
Company. If any tendered Private Notes are not accepted for exchange because of
an invalid tender, the occurrence of certain other events set forth herein, or
otherwise, certificates for any such unaccepted Private Notes will be returned
(or, in the case of Private Notes tendered by book-entry transfer, such
unaccepted Private Notes will be credited to an account maintained at DTC),
without expense, to the tendering Holder thereof as promptly as practicable
after the Expiration Date. See "-- Procedures for Tendering."
 
                                       36
<PAGE>   44
 
     Holders who tender Private Notes in the Exchange Offer will not be required
to pay brokerage commissions or fees or, subject to the instructions in the
Letter of Transmittal, transfer taxes with respect to the exchange pursuant to
the Exchange Offer. The Company will pay all charges and expenses, other than
certain applicable taxes described below, in connection with the Exchange Offer.
See "-- Fees and Expenses."
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
     The term "Expiration Date," shall mean 5:00 p.m., New York City time on
                    , 1998, unless the Company, in its sole discretion, extends
the Exchange Offer, in which case the term "Expiration Date" shall mean the
latest date and time to which the Exchange Offer is extended.
 
     In order to extend the Exchange Offer, the Company will notify the Exchange
Agent of any extension by oral or written notice prior to 9:00 a.m., New York
City time, on the next business day after the previously scheduled Expiration
Date and will make a public announcement thereof.
 
     The Company reserves the right, in its sole discretion, (i) to delay
accepting any Private Notes, to extend the Exchange Offer or to terminate the
Exchange Offer if any of the conditions set forth below under "Conditions" shall
not have been satisfied by giving oral or written notice of such delay,
extension, or termination to the Exchange Agent or (ii) to amend the terms of
the Exchange Offer in any manner consistent with the Registration Rights
Agreement. Any such delay in acceptances, extension, termination, or amendment
will be followed as promptly as practicable by oral or written notice thereof to
the registered Holders. If the Exchange Offer is amended in a manner determined
by the Company to constitute a material change, the Company will promptly
disclose such amendment by means of a prospectus supplement that will be
distributed to the registered Holders, and the Company will extend the Exchange
Offer for a period of five to ten business days, depending upon the significance
of the amendment and the manner of disclosure to the registered Holders, if the
Exchange Offer would otherwise expire during such five to ten business day
period.
 
     Without limiting the manner in which the Company may choose to make a
public announcement of any delay, extension, amendment, or termination of the
Exchange Offer, the Company shall have no obligation to publish, advertise, or
otherwise communicate any such public announcement, other than by making a
timely release to an appropriate news agency.
 
     Upon satisfaction or waiver of all the conditions to the Exchange Offer,
the Company will accept, promptly after the Expiration Date, all Private Notes
properly tendered and will issue the Exchange Senior Notes promptly after
acceptance of the Private Notes. See "-- Conditions" below. For purposes of the
Exchange Offer, the Company shall be deemed to have accepted properly tendered
Private Notes for exchange when, as and if the Company shall have given oral or
written notice thereof to the Exchange Agent.
 
     In all cases, issuance of the Exchange Senior Notes for Private Notes that
are accepted for exchange pursuant to the Exchange Offer will be made only after
timely receipt by the Exchange Agent of certificates for such Private Notes or a
timely Book-Entry Confirmation of such Private Notes into the Exchange Agent's
account at DTC, a properly completed and duly executed Letter of Transmittal,
and all other required documents; provided, however, that the Company reserves
the absolute right to waive any defects or irregularities in the tender or
conditions of the Exchange Offer. If any tendered Private Notes are not accepted
for any reason set forth in the terms and conditions of the Exchange Offer, the
Holder withdraws such previously tendered Private Notes, or if Private Notes are
submitted for a greater principal amount of Private Notes than the Holder
desires to exchange, then such unaccepted, withdrawn or portion of non-exchanged
Private Notes, as appropriate, will be returned as promptly as practicable after
the expiration or termination of the Exchange Offer (or, in the case of Private
Notes tendered by book-entry transfer, such unaccepted, withdrawn or portion of
non-exchanged Private Notes, as appropriate, will be credited to an account
maintained with DTC) without expense to the tendering Holder thereof.
 
                                       37
<PAGE>   45
 
CONDITIONS
 
     Notwithstanding any other term of the Exchange Offer, the Company will not
be required to exchange any Exchange Senior Notes for any Private Notes and may
terminate the Exchange Offer before the acceptance of any Private Notes for
exchange, if:
 
          (i) any action or proceeding is instituted or threatened in any court
     or by or before any governmental agency with respect to the Exchange Offer
     which, in the Company's reasonable judgment, might materially impair the
     ability of the Company to proceed with the Exchange Offer; or
 
          (ii) any law, statute, rule or regulation is proposed, adopted or
     enacted, or any interpretation of any existing law, statute, rule or
     regulation is issued by the staff of the Commission, which, in the
     Company's reasonable judgment, might materially impair the ability of the
     Company to proceed with the Exchange Offer; or
 
          (iii) any governmental approval or approval by Holders of the Private
     Notes has not been obtained, which approval the Company shall, in its
     reasonable judgment, deem necessary for the consummation of the Exchange
     Offer as contemplated hereby.
 
     If the Company determines in its sole discretion that any of these
conditions are not satisfied, the Company may (i) refuse to accept any Private
Notes and return all tendered Private Notes to the tendering Holders (or, in the
case of Private Notes tendered by book-entry transfer, credit such Private Notes
at an account maintained with DTC), (ii) extend the Exchange Offer and retain
all Private Notes tendered prior to the expiration of the Exchange Offer,
subject, however, to the rights of Holders who tendered such Private Notes to
withdraw their tendered Private Notes, or (iii) waive such unsatisfied
conditions with respect to the Exchange Offer and accept all properly tendered
Private Notes that have not been withdrawn. If such waiver constitutes a
material change to the Exchange Offer, the Company will promptly disclose such
waiver by means of a prospectus supplement that will be distributed to the
registered Holders, and the Company will extend the Exchange Offer for a period
of five to ten business days, depending upon the significance of the waiver and
the manner of disclosure to the registered Holders, if the Exchange Offer would
otherwise expire during such five to ten business day period.
 
PROCEDURES FOR TENDERING
 
     To tender in the Exchange Offer, a Holder must complete, sign and date the
Letter of Transmittal, or facsimile thereof, have the signatures thereon
guaranteed if required by the Letter of Transmittal, and mail or otherwise
deliver such Letter of Transmittal or such facsimile to the Exchange Agent prior
to the Expiration Date. In addition, either (i) certificates for such Private
Notes must be received by the Exchange Agent along with the Letter of
Transmittal, or (ii) a timely confirmation of book-entry transfer (a "Book-Entry
Confirmation") of such Private Notes, if such procedure is available, into the
Exchange Agent's account at DTC pursuant to the procedure for book-entry
transfer described below must be received by the Exchange Agent prior to the
Expiration Date, or (iii) the Holder must comply with the guaranteed delivery
procedures described below. To be tendered effectively, the Letter of
Transmittal and other required documents must be received by the Exchange Agent
at the address set forth below under "Exchange Agent" prior to the Expiration
Date.
 
     The tender by a Holder of Private Notes that is not withdrawn prior to the
Expiration Date will constitute an agreement between such Holder and the Company
in accordance with the terms and subject to the conditions set forth herein and
in the Letter of Transmittal.
 
     THE METHOD OF DELIVERY OF PRIVATE NOTES AND THE LETTER OF TRANSMITTAL AND
ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK
OF THE HOLDER. INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS USE
AN OVERNIGHT OR HAND DELIVERY SERVICE, PROPERLY INSURED. IN ALL CASES,
SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE AGENT
BEFORE THE EXPIRATION DATE. NO LETTER OF TRANSMITTAL OR PRIVATE NOTES SHOULD BE
SENT TO THE COMPANY. HOLDERS MAY
 
                                       38
<PAGE>   46
 
REQUEST THEIR RESPECTIVE BROKERS, DEALERS, COMMERCIAL BANKS, TRUST COMPANIES, OR
NOMINEES TO EFFECT THE ABOVE TRANSACTIONS FOR SUCH HOLDERS.
 
     Any beneficial owner whose Private Notes are registered in the name of a
broker, dealer, commercial bank, trust company, or other nominee and who wishes
to tender its Private Notes should contact the registered Holder promptly and
instruct such registered Holder to tender such Private Notes on such beneficial
owner's behalf. If such beneficial owner wishes to tender its Private Notes on
such owner's own behalf, such owner must, prior to completing and executing the
Letter of Transmittal and delivering such owner's Private Notes, either make
appropriate arrangements to register ownership of the Private Notes in such
owner's name or obtain a properly completed assignment from the registered
Holder. The transfer of registered ownership of Private Notes may take
considerable time.
 
     Signatures on a Letter of Transmittal or a notice of withdrawal, as the
case may be, must be guaranteed by an Eligible Institution (as defined herein)
unless the Private Notes tendered pursuant thereto are tendered (i) by a
registered Holder who has not completed the box entitled "Special Payment
Instructions" or "Special Delivery Instructions" on the Letter of Transmittal or
(ii) for the account of an Eligible Institution. In the event that signatures on
a Letter of Transmittal or a notice of withdrawal, as the case may be, are
required to be guaranteed, such guarantor must be a member firm of a registered
national securities exchange or of the National Association of Securities
Dealers, Inc., a commercial bank or trust company having an office or
correspondent in the U.S. or an "eligible guarantor institution" within the
meaning of Rule 17Ad-15 under the Exchange Act (each, an "Eligible
Institution").
 
     If the Letter of Transmittal is signed by a person other than the
registered Holder of any Private Notes listed therein, such Private Notes must
be endorsed or accompanied by a properly completed bond power, signed by such
registered Holder as such registered Holder's name appears on such Private
Notes.
 
     If the Letter of Transmittal or any Private Notes or bond powers are signed
by trustees, executors, administrators, guardians, attorneys-in-fact, officers
of corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and unless waived by the Company,
evidence satisfactory to the Company of their authority to so act must be
submitted with the Letter of Transmittal.
 
     All questions as to the validity, form, eligibility (including time of
receipt), acceptance of tendered Private Notes, and withdrawal of tendered
Private Notes will be determined by the Company in its sole discretion, which
determination will be final and binding. The Company reserves the absolute right
to reject any and all Private Notes not properly tendered or any Private Notes
the Company's acceptance of which would, in the opinion of counsel for the
Company, be unlawful. The Company also reserves the right to waive any defects,
irregularities, or conditions of tender as to particular Private Notes. The
Company's interpretation of the terms and conditions of the Exchange Offer
(including the instructions in the Letter of Transmittal) will be final and
binding on all parties. Unless waived, any defects or irregularities in
connection with tenders of Private Notes must be cured within such time as the
Company shall determine. Although the Company intends to notify Holders of
defects or irregularities with respect to tenders of Private Notes, none of the
Company, the Exchange Agent or any other person shall incur any liability for
failure to give such notification. Tenders of Private Notes will not be deemed
to have been made until such defects or irregularities have been cured or
waived. Any Private Notes received by the Exchange Agent that are not properly
tendered and as to which the defects or irregularities have not been cured or
waived will be returned by the Exchange Agent to the tendering Holders, unless
otherwise provided in the Letter of Transmittal, as soon as practicable
following the Expiration Date.
 
     In addition, the Company reserves the right in its sole discretion, to
purchase or make offers for any Private Notes that remain outstanding subsequent
to the Expiration Date or, as set forth above under "-- Conditions," to
terminate the Exchange Offer and, to the extent permitted by applicable law and
the terms of its agreements relating to its outstanding indebtedness, purchase
Private Notes in the open market, in privately negotiated transactions or
otherwise. The terms of any such purchases or offers could differ from the terms
of the Exchange Offer.
 
                                       39
<PAGE>   47
 
     By tendering, each Holder will represent to the Company that, among other
things, (i) the Exchange Senior Notes acquired pursuant to the Exchange Offer
are being obtained in the ordinary course of business of the person receiving
such Exchange Senior Notes, whether or not such person is the Holder, (ii)
neither the Holder nor any such other person is engaging in or intends to engage
in a distribution of such Exchange Senior Notes, (iii) neither the Holder nor
any such other person has an arrangement or understanding with any person to
participate in the distribution of such Exchange Senior Notes, and (iv) neither
the Holder nor any such other person is an "affiliate" (as defined in Rule 405
of the Securities Act) of the Company. If the Holder is a Participating
Broker-Dealer that will receive Exchange Senior Notes for such Holder's own
account in exchange for Private Notes that were acquired as a result of
market-making activities or other trading activities, such Holder will be
required to acknowledge in the Letter of Transmittal that such Holder will
deliver a prospectus in connection with any resale of such Exchange Senior Notes
and otherwise agree to comply with the procedures described above under
"-- Resale of the Exchange Senior Notes"; however, by so acknowledging and
delivering a prospectus, such holder will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.
 
     In all cases, issuance of Exchange Senior Notes pursuant to the Exchange
Offer will be made only after timely receipt by the Exchange Agent of
certificates for such Private Notes or a timely Book-Entry Confirmation of such
Private Notes into the Exchange Agent's account at DTC, a properly completed and
duly executed Letter of Transmittal, and all other required documents. If any
tendered Private Notes are not accepted for any reason set forth in the terms
and conditions of the Exchange Offer or if Private Notes are submitted for a
greater principal amount of Private Notes than the Holder desires to exchange,
such unaccepted or portion of non-exchanged Private Notes will be returned as
promptly as practicable after the expiration or termination of the Exchange
Offer (or, in the case of Private Notes tendered by book-entry transfer into the
Exchange Agent's account at DTC pursuant to the book-entry transfer procedures
described below, such unaccepted or portion of non-exchanged Private Notes will
be credited to an account maintained with DTC) without expense to the tendering
Holder thereof.
 
BOOK-ENTRY TRANSFER
 
     The Exchange Agent will make a request to establish an account with respect
to the Private Notes at DTC for the purposes of the Exchange Offer within two
business days after the date of this Prospectus, and any financial institution
that is a participant in DTC's systems may make book-entry delivery of Private
Notes by causing DTC to transfer such Private Notes into the Exchange Agent's
account at DTC in accordance with DTC's procedures for transfer. However,
although delivery of Private Notes may be effected through book-entry transfer
at DTC, the Letter of Transmittal or facsimile thereof, with any required
signature guarantees and any other required documents, must, in any case, be
transmitted to and received by the Exchange Agent at the address set forth below
under "Exchange Agent" on or prior to the Expiration Date (unless the Holder
complies with the guaranteed delivery procedures described below).
 
GUARANTEED DELIVERY PROCEDURES
 
     Holders who wish to tender their Private Notes and (x) whose Private Notes
are not immediately available or (y) who cannot deliver their Private Notes, the
Letter of Transmittal, or any other required documents to the Exchange Agent
prior to the Expiration Date, may effect a tender if:
 
          (i) The tender is made through an Eligible Institution;
 
          (ii) Prior to the Expiration Date, the Exchange Agent receives from
     such Eligible Institution a properly completed and duly executed Notice of
     Guaranteed Delivery substantially in the form provided by the Company (by
     facsimile transmission, mail or hand delivery) setting forth the name and
     address of the Holder, the certificate number(s) of such Private Notes and
     the principal amount of Private Notes tendered and stating that the tender
     is being made thereby and guaranteeing that, within three New York Stock
     Exchange trading days after the Expiration Date, the Letter of Transmittal
     (or facsimile thereof) together with the certificate(s) representing the
     Private Notes in proper form for transfer or a Book-Entry
 
                                       40
<PAGE>   48
 
     Confirmation, as the case may be, and any other documents required by the
     Letter of Transmittal will be deposited by the Eligible Institution with
     the Exchange Agent; and
 
          (iii) Such properly completed and executed Letter of Transmittal (or
     facsimile thereof), as well as the certificate(s) representing all tendered
     Private Notes in proper form for transfer and other documents required by
     the Letter of Transmittal are received by the Exchange Agent within three
     New York Stock Exchange trading days after the Expiration Date.
 
     Upon request to the Exchange Agent, a Notice of Guaranteed Delivery will be
sent to Holders who wish to tender their Private Notes according to the
guaranteed delivery procedures set forth above.
 
WITHDRAWAL OF TENDERS
 
     Except as otherwise provided herein, tenders of Private Notes may be
withdrawn at any time prior to 5:00 p.m., New York City time, on the Expiration
Date.
 
     To withdraw a tender of Private Notes in the Exchange Offer, a written or
facsimile transmission notice of withdrawal must be received by the Exchange
Agent at its address set forth herein prior to 5:00 p.m., New York City time, on
the Expiration Date. Any such notice of withdrawal must (i) specify the name of
the person having deposited the Private Notes to be withdrawn (the "Depositor"),
(ii) identify the Private Notes to be withdrawn (including the certificate
number(s)), (iii) be signed by the Holder in the same manner as the original
signature on the Letter of Transmittal by which such Private Notes were tendered
(including any required signature guarantees) or be accompanied by documents of
transfer sufficient to have the Exchange Agent register the transfer of such
Private Notes in the name of the person withdrawing the tender, and (iv) specify
the name in which any such Private Notes are to be registered, if different from
that of the Depositor. All questions as to the validity, form, and eligibility
(including time of receipt) of such notices will be determined by the Company,
whose determination shall be final and binding on all parties. Any Private Notes
so withdrawn will be deemed not to have been validly tendered for purposes of
the Exchange Offer, and no Exchange Senior Notes will be issued with respect
thereto unless the Private Notes so withdrawn are validly retendered. Any
Private Notes that have been tendered but that are not accepted for payment will
be returned to the Holder thereof (or, in the case of Private Notes tendered by
book-entry transfer, will be credited to an account maintained with DTC),
without cost to such Holder as soon as practicable after withdrawal, rejection
of tender or termination of the Exchange Offer. Properly withdrawn Private Notes
may be retendered by following one of the procedures described above under
"-- Procedures for Tendering" at any time prior to the Expiration Date.
 
TERMINATION OF CERTAIN RIGHTS
 
     All rights under the Registration Rights Agreement accorded to Holders of
Private Notes will terminate upon the consummation of the Exchange Offer except
with respect to the Company's duty to keep the Registration Statement effective
until the closing of the Exchange Offer and, for a period not to exceed 90 days
after the Expiration Date, to provide copies of the latest version of this
Prospectus to any broker-dealer that requests copies of such Prospectus for use
in connection with any resale by such broker-dealer of Exchange Senior Notes
received for its own account pursuant to the Exchange Offer in exchange for
Private Notes acquired for its own account as a result of market-making or other
trading activities, subject to the conditions described above under "-- Resale
of the Exchange Senior Notes."

FEES AND EXPENSES
 
     The expenses of soliciting tenders in connection with the Exchange Offer
will be paid by the Company. The principal solicitation is being made by mail;
however, additional solicitation may be made by telecopier, telephone, or in
person by officers and regular employees of the Company and its affiliates.
 
     The Company has not retained any dealer-manager in connection with the
Exchange Offer and will not make any payments to broker-dealers or others
soliciting acceptances of the Exchange Offer. The Company, however, will pay the
Exchange Agent reasonable and customary fees for its services and will reimburse
it for its reasonable out-of-pocket expenses in connection therewith.
 
     The cash expenses to be incurred in connection with the Exchange Offer will
be paid by the Company and are estimated in the aggregate to be approximately
$225,000. Such expenses include registration fees, fees and expenses of the
Exchange Agent, accounting and legal fees, and printing costs, among others.
 
     The Company will pay all transfer taxes, if any, applicable to the exchange
of the Private Notes pursuant to the Exchange Offer. If, however, certificates
representing Private Notes not tendered or accepted for exchange are to be
delivered to, or are to be issued in the name of, any person other than the
registered Holder of Private Notes tendered, or, if tendered, the certificates
representing Private Notes are registered in the name of any person other than
the person signing the Letter of Transmittal, or if a transfer tax is imposed
for any reason other than the exchange of the Private Notes pursuant to the
Exchange Offer, then the amount of any such transfer taxes (whether imposed on
the registered Holder or any other persons) will be payable by the tendering
Holder. If satisfactory evidence of payment of such transfer taxes or exemption
therefrom is not submitted with the Letter of Transmittal, the amount of such
transfer taxes will be billed directly to such tendering Holder.
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
     Participation in the Exchange Offer is voluntary. Holders of the Private
Notes are urged to consult their financial and tax advisors in making their own
decisions on what action to take.
 
     Private Notes that are not exchanged for the Exchange Senior Notes pursuant
to the Exchange Offer will not retain any rights under the Registration Rights
Agreement and will remain "restricted securities" within the meaning of Rule
144(a)(3)(iv) of the Securities Act. Accordingly, such Private Notes may not be
offered, sold, pledged, or otherwise transferred except (i) to Nextel or any
subsidiary thereof, (ii) to a "qualified institutional buyer" within the meaning
of Rule 144A under the Securities Act purchasing for its own account or for the
account of a qualified institutional buyer in a transaction meeting the
requirements of Rule 144A, (iii) in an offshore transaction complying with Rule
904 of Regulation S under the Securities Act,
 
                                       42
<PAGE>   50
 
(iv) pursuant to an exemption from registration under the Securities Act
provided by Rule 144 thereunder (if available), (v) to "institutional accredited
investors" in a transaction exempt from the registration requirements of the
Securities Act, or (vi) pursuant to an effective registration statement under
the Securities Act, and, in each case, in accordance with all other applicable
securities laws.
 
ACCOUNTING TREATMENT
 
     For accounting purposes, the Company will recognize no gain or loss as a
result of the Exchange Offer. The Exchange Senior Notes will be recorded at the
same carrying value as the Private Notes, as reflected in the Company's
accounting records on the date of the exchange. The expenses of the Exchange
Offer will be amortized over the term of the Exchange Senior Notes.
 
TAX CONSEQUENCES
 
     For a description of certain United States Federal income tax consequences
to holders of Private Notes tendering in the Exchange Offer, see "Certain United
States Federal Income Tax Consequences."

                      DESCRIPTION OF EXCHANGE SENIOR NOTES
 
     The Private Notes were, and the Exchange Senior Notes will be, issued under
the Indenture, dated as of October 22, 1997, between the Company, as issuer, and
Harris Trust and Savings Bank, as Trustee. The form and terms of the Exchange
Senior Notes will be the same as the form and terms of the Private Notes except
that the Exchange Senior Notes will be registered under the Securities Act and
hence will not bear legends restricting the transfer thereof. Following
consummation of the Exchange Offer, all rights under the Registration Rights
Agreement accorded to holders of Private Notes, including the right to receive
additional incremental interest on the Private Notes, to the extent and in the
circumstances specified therein, will terminate. The terms of the Notes include
those stated in the Indenture and those made part of the Indenture by reference
to the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). The
Notes are subject to all such terms, and holders of the Notes are referred to
the Indenture and the Trust Indenture Act for a statement of such terms. The
following summary of certain provisions of the Indenture does not purport to be
complete and is subject to, and is qualified in its entirety by reference to,
the Trust Indenture Act and to all of the provisions of the Indenture, including
the definitions of certain terms therein and those terms made a part of the
Indenture by reference to the Trust Indenture Act. A copy of the Indenture has
been filed as an exhibit to the Registration Statement of which this Prospectus
is a part.
 
CERTAIN DEFINITIONS
 
     Set forth below is a summary of certain of the defined terms used in the
covenants and other provisions of the Exchange Senior Notes and Indenture.
Reference is made to the terms of the Exchange Senior Notes and Indenture for
the full definitions of all such terms as well as any other capitalized terms
used herein for which no definition is provided.
 
     Whenever the Indenture requires that a particular ratio or amount be
calculated with respect to a specified period after giving effect to certain
transactions or events on a pro forma basis, such calculation will be made as if
the transactions or events occurred on the first day of such period, unless
otherwise specified. All accounting terms not otherwise defined in the Indenture
shall have the meanings ascribed to them in accordance with generally accepted
accounting principles (whether or not such is indicated in the Indenture) and,
except as otherwise expressly provided in the Indenture, the term "generally
accepted accounting principles," with respect to any computation required or
permitted by the Indenture shall mean such accounting principles as are
generally accepted at the date of such computation.
 
     "Accreted Value" of any outstanding Note as of or to any date of
determination means an amount equal to the sum of (i) the issue price of such
Note as determined in accordance with Section 1273 of the Internal Revenue Code
of 1986, as amended (the "Code") (which issue price is the same for the Exchange
Senior Notes as the issue price of the Private Notes since the Exchange Senior
Notes should be treated as a continuation of the Private Notes for United States
Federal income tax purposes) plus (ii) the aggregate of the portions of the
original issue discount (the excess of the amounts considered as part of the
"stated redemption price at maturity" of such Note within the meaning of Section
1273(a)(2) of the Code or any successor provisions, whether denominated as
principal or interest, over the issue price of such Note) that shall theretofore
have accrued pursuant to Section 1272 of the Code (without regard to Section
1272(a)(7) of the Code) from the date of issue of the Private Note (a) for each
six-month or shorter period ending April 30 or October 31 prior to the date of
determination (each a "Semi-Annual Accrual Date") and (b) for the shorter
period, if any, from the end of the immediately preceding six-month or shorter
period, as the case may be, to the date of determination, plus (iii) accrued and
unpaid interest to the date such Accreted Value is paid (without duplication of
any amount set forth in (ii) above), minus all amounts theretofore paid in
respect of such Note, which amounts are considered as part of the "stated
redemption price at maturity" of such Note within the meaning of Section
1273(a)(2) of the Code or any successor provisions (whether such amounts paid
were denominated principal or interest).
 
     "Acquired Debt" means Debt of a Person existing at the time such Person
becomes a Restricted Subsidiary or assumed by the Company or a Restricted
Subsidiary in connection with the acquisition of assets from such Person.
 
                                       47
<PAGE>   55
 
     "Affiliate" of any specified Person means any other Person directly or
indirectly controlling or controlled by or under direct or indirect common
control with such Person. "Affiliate" shall be deemed to include, but only for
purposes of the "Transactions with Affiliates" covenant and without limiting the
application of the preceding sentence for the purpose of such or any other
section, any Person owning, directly or indirectly, (i) 10% or more of the
Company's outstanding Common Stock or (ii) securities having 10% or more of the
total voting power of the Company's Voting Stock. For the purposes of this
definition, "control" when used with respect to any specified Person means the
power to direct the management and policies of such Person, directly or
indirectly, whether through the ownership of voting securities, by contract or
otherwise; and the terms "controlling" and "controlled" have meanings
correlative to the foregoing. No individual shall be deemed to be controlled by
or under common control with any specified Person solely by virtue of his or her
status as an employee or officer of such specified Person or of any other Person
controlled by or under common control with such specified Person.
 
     "Annualized Operating Cash Flow" means, for any fiscal quarter, the
Operating Cash Flow for such fiscal quarter multiplied by four.
 
     "Average Life" means, at any date of determination with respect to any
Debt, the quotient obtained by dividing (i) the sum of the products of (a) the
number of years from such date of determination to the dates of each successive
scheduled principal payment of such Debt and (b) the amount of such principal
payment by (ii) the sum of all such principal payments.
 
     "Beneficial Owner" means a beneficial owner as defined in Rules 13d-3 and
13d-5 under the Exchange Act (or any successor rules), including the provision
of such Rules that a person shall be deemed to have beneficial ownership of all
securities that such person has a right to acquire within 60 days, provided that
a person shall not be deemed a beneficial owner of, or to own beneficially, any
securities if such beneficial ownership (i) arises solely as a result of a
revocable proxy delivered in response to a proxy or consent solicitation made
pursuant to, and in accordance with, the Exchange Act and the applicable rules

     In addition, on or prior to October 31, 2000, the Company may redeem Notes
having an aggregate principal amount of up to 33 1/3% of the aggregate Accreted
Value of the outstanding Notes at a redemption price equal to 109.75% of the
Accreted Value thereof to the redemption date, out of the net proceeds of one or
more sales of at least $125,000,000 of its Capital Stock (other than Redeemable
Stock), provided that such redemption occurs within 180 days after consummation
of such sale.
 
  Selection
 
     In the case of any partial redemption, selection of the Notes for
redemption will be made by the Trustee in compliance with the requirements of
the principal national securities exchange, if any, on which the Notes are
listed or, if the Notes are not listed on a national securities exchange, on a
pro rata basis, by lot or by such other method as the Trustee in its sole
discretion shall deem to be fair and appropriate; provided that no Notes of
$1,000 in principal amount or less shall be redeemed in part. If any Notes are
to be redeemed in part only, the notice of redemption relating to such Notes
shall state the portion of the principal amount thereof to be redeemed. A new
Note in principal amount equal to the unredeemed portion thereof will be issued
in the name of the Holder thereof upon cancellation of the original Note.
 
CHANGE OF CONTROL
 
     Upon the occurrence of a Change of Control, the Company will be required to
make an Offer to Purchase to each Holder of Notes to repurchase all or any part
of such Holder's Notes at a cash purchase price equal to 101% of the Accreted
Value thereof on any purchase date prior to October 31, 2002 or 101% of the
principal amount thereof, plus accrued and unpaid interest to the date of
purchase on or after October 31, 2002 (the "Change of Control Payment"). The
Offer to Purchase must be made within 30 days following a Change of
 
                                       61
<PAGE>   69
 
Control, must remain open for at least 30 and not more than 60 days, and must
comply with the requirements of Rule 14e-1 under the Exchange Act and any other
applicable securities laws and regulations.
 
     None of the provisions in the Indenture relating to a purchase upon a
Change of Control are waivable by the Board of Directors. The Company could, in
the future, enter into certain transactions, including certain recapitalizations
of the Company, that would not constitute a Change of Control, but would
increase the amount of indebtedness outstanding at such time. If a Change of
Control were to occur, the Company would be obligated to offer to purchase
outstanding shares of the Exchangeable Preferred Stock, as well as to purchase
all Debt which then would be entitled to receive a comparable offer to purchase
by reason of such Change of Control, in addition to making an offer to
repurchase the Notes. There can be no assurance that the Company would have
sufficient funds to pay the purchase price for all Notes that the Company would
be required to purchase if a Change of Control were to occur. In the event that
the Company were required to purchase the outstanding Notes pursuant to an Offer
to Purchase, the Company expects that it would need to seek third-party
financing to the extent it does not have available funds to meet its purchase
obligations. However, there can be no assurance that the Company would be able
to obtain such financing. In addition, the Company's ability to purchase the
Notes may be limited by other then-existing agreements.
 
CERTAIN COVENANTS
 
  Limitation on Consolidated Debt
 
     The Company shall not, and shall not permit any Restricted Subsidiary to,
Incur any Debt (including Acquired Debt), other than Permitted Debt, unless (i)
with respect to Debt Incurred under this clause (i), the Debt so Incurred and
outstanding is in an aggregate principal amount that does not exceed 2.25 times,
with respect to Capital Stock sales after June 1, 1997, and on or prior to March
31, 1998, or 2.00 times, with respect to Capital Stock sales after March 31,
1998, the aggregate amount of net cash proceeds (or 80% of the Fair Market Value
of property other than cash) received by the Company after June 1, 1997, from
the issuance and sale (other than to a Restricted Subsidiary) of shares of its
Capital Stock (other than Redeemable Stock), or any options, warrants, or other
rights to purchase such Capital Stock (other than Redeemable Stock), other than
(x) proceeds applied for use as a Directed Investment (unless such designation
has been revoked by the Board of Directors and the Company either abandons its
plans to make such Investment or is able to make such Investment pursuant to the
"Limitation on Restricted Payments" covenant (other than as a Directed
Investment)) and (y) proceeds which have been included in the computation of the
amounts available for Restricted Payments pursuant to clause (c)(2) of the
"Limitation on Restricted Payments" covenant, to the extent the inclusion
thereof was necessary to allow a subsequent Restricted Payment to be made, or
(ii) on the date of such Incurrence, after giving effect to the Incurrence of
such Debt (or Acquired Debt) and the receipt and application of the net proceeds
thereof (and, if the net proceeds of such new Debt are used to acquire a Person
that becomes a Restricted Subsidiary or an operating business of the Company or
a Restricted Subsidiary, to all terms of such acquisition) on a pro forma basis,
the Operating Cash Flow to Consolidated Interest Expense Ratio would equal or
exceed 1.75 to 1.
 
  Limitation on Restricted Payments
 
     The Company shall not, directly or indirectly:
 
          (i) declare or pay any dividend on, or make any distribution to the
     holders of, any shares of its Capital Stock (other than dividends or
     distributions payable solely in its Capital Stock (other than Redeemable
     Stock) or in options, warrants, or other rights to purchase any such
     Capital Stock (other than Redeemable Stock));
 
          (ii) purchase, redeem, or otherwise acquire or retire for value, or
     permit any Restricted Subsidiary to, directly or indirectly, purchase,
     redeem, or otherwise acquire or retire for value (other than value
     consisting solely of Capital Stock of the Company that is not Redeemable
     Stock or options, warrants, or other rights to acquire such Capital Stock
     that is not Redeemable Stock), any Capital Stock of the Company (including
     options, warrants, or other rights to acquire such Capital Stock);
 
                                       62
<PAGE>   70
 
          (iii) redeem, repurchase, defease, or otherwise acquire or retire for
     value, or permit any Restricted Subsidiary to, directly or indirectly,
     redeem, repurchase, defease or otherwise acquire or retire for value (other
     than value consisting solely of Capital Stock of the Company that is not
     Redeemable Stock or options, warrants or other rights to acquire such
     Capital Stock that is not Redeemable Stock), prior to any scheduled
     maturity, scheduled repayment or scheduled sinking fund payment, any Debt
     that is subordinate (whether pursuant to its terms or by operation of law)
     in right of payment to the Notes; or
 
          (iv) make, or permit any Restricted Subsidiary, directly or
     indirectly, to make, any Investment (other than any Permitted Investment)
     in any Person (other than in a Restricted Subsidiary or a Person that
     becomes a Restricted Subsidiary as a result of such Investment);
 
(each of the foregoing actions set forth in clauses (i) through (iv), other than
any such action that is a Permitted Investment or a Permitted Distribution,
being referred to as a "Restricted Payment") unless, at the time of such
Restricted Payment, and after giving effect thereto:
 
          (a) no Default or Event of Default shall have occurred and be
     continuing;
 
          (b) except with respect to Investments, after giving effect, on a pro
     forma basis, to such Restricted Payment and the Incurrence of any Debt the
     net proceeds of which are used to finance such Restricted Payment, the
     Consolidated Debt to Annualized Operating Cash Flow Ratio would not have
     exceeded 7.0 to 1; and
 
          (c) after giving effect to such Restricted Payment on a pro forma
     basis, the aggregate amount of all Restricted Payments made on or after
     February 15, 1994, shall not exceed:
 
             (1) 50% of the Consolidated Net Income (or, in the case of a
        Consolidated Net Loss, minus 100% of such deficit) of the Company for
        the period (taken as one accounting period) from April 1, 1994, to the
        last day of the last fiscal quarter preceding the date of the proposed
        Restricted Payment, plus
 
             (2) the aggregate net proceeds, including the fair market value of
        property other than cash (as determined by the Board of Directors, whose
        good faith determination shall be conclusive and evidenced by a Board
        Resolution), received by the Company from the issuance and sale (other
        than to a Restricted Subsidiary) on or after February 15, 1994, of
        shares of its Capital Stock (other than Redeemable Stock), or any
        options, warrants or other rights to purchase such Capital Stock (other
        than Redeemable Stock), other than (x) (except for purposes of
        determining whether an Investment under clause (iv) above is permitted)
        shares of Capital Stock or options, warrants, or other rights to
        purchase Capital Stock (or shares issuable upon exercise thereof) issued
        or sold in the PowerFone Merger, Questar/AMI Share Exchanges, Motorola
        Transaction, and NTT transactions as defined and described in the
        Company's prospectus, dated February 9, 1994, relating to the Company's
        Senior Redeemable Discount Notes due 2004 and (y) shares of Capital
        Stock or options, warrants, or other rights to purchase Capital Stock
        (or shares issuable upon exercise thereof), the proceeds of the issuance
        of which is used (A) to make a Directed Investment (unless such
        designation has been revoked by the Board of Directors and the Company
        is able to make such Investment pursuant to this "Limitation on
        Restricted Payments" covenant (other than as a Directed Investment)) or
        (B) to Incur Debt under clause (i) of the "Limitation on Consolidated
        Debt" covenant (unless and until the amount of any such Debt (I) is
        treated as newly issued Debt and could be Incurred in accordance with
        the "Limitation on Consolidated Debt" covenant (other than under clause
        (i) thereof) or (II) has been repaid or refinanced with the proceeds of
        Debt Incurred in accordance with the "Limitation on Consolidated Debt"
        covenant (other than under clause (i) thereof) or (III) has otherwise
        been repaid), plus
 
             (3) the aggregate net proceeds, including the fair market value of
        property other than cash (as determined by the Board of Directors, whose
        good faith determination shall be conclusive and evidenced by a Board
        Resolution), received by the Company from the issuance or sale (other
        than to a Restricted Subsidiary) after February 15, 1994, of any Capital
        Stock of the Company (other than Redeemable Stock), or any options,
        warrants, or other rights to purchase such Capital Stock (other
 
                                       63
<PAGE>   71
 
        than Redeemable Stock), upon the conversion of, or exchange for, Debt of
        the Company or a Restricted Subsidiary.
 
     The foregoing limitations in this "Limitation on Restricted Payments"
covenant do not limit or restrict the making of any Permitted Distribution,
Permitted Investment, or Directed Investment, and none of a Permitted
Distribution, Permitted Investment, or Directed Investment shall be counted as a
Restricted Payment for purposes of clause (c) above. In addition, the foregoing
limitations do not prevent the Company from (I) paying a dividend on Capital
Stock of the Company within 60 days after the declaration thereof if, on the
date when the dividend was declared, the Company could have paid such dividend
in accordance with the provisions of the Indenture, (II) repurchasing Capital
Stock of the Company (including options, warrants, or other rights to acquire
such Capital Stock) from employees or former employees of the Company or any
Subsidiary thereof for consideration not to exceed $500,000 in the aggregate in
any fiscal year (with repurchases pursuant to this clause (II) not being counted
as Restricted Payments for purposes of clause (c) above) or (III) the
repurchase, redemption, or other acquisition for value of Capital Stock of the
Company to the extent necessary to prevent the loss or secure the renewal or
reinstatement of any license or franchise held by the Company or any of its
Subsidiaries from any governmental agency; or (IV) Investments in Unrestricted
Subsidiary Funding Company so long as (x) such Investments are invested in
Nextel International and (y) Nextel International is a Subsidiary of the
Company.
 
     Notwithstanding the foregoing limitations in this "Limitation on Restricted
Payments" covenant, the Company is permitted to make any Investment in a Person
that is not (either before or after giving effect thereto) a Subsidiary of the
Company, provided that, immediately after giving effect thereto, the amount
equal to (i) the aggregate amount of all Investments made pursuant to this
paragraph minus (ii) all cash received by the Company or any Restricted
Subsidiary from the sale, transfer or other disposition to a Person that is not
a Subsidiary of the Company of any such Investment (or portion thereof) included
in such aggregate amount (with the amount of cash to be counted for this purpose
not to exceed the amount of such Investment (or portion thereof) so included),
shall not exceed the greater of (x) $250 million and (y) 2% of the Total Market
Value of Equity of the Company as of such time. For purposes of determining the
aggregate amount of Investments referred to in clause (i), the amount of any
Investment shall be deemed to equal the cash portion thereof plus the fair
market value of any non-cash portion thereof (to the extent such portion
constitutes an Investment) at the time such Investment is made, as determined by
the Board of Directors (whose good faith determination shall be conclusive and
evidenced by a Board Resolution).
 
     Notwithstanding the foregoing, no Investment in a Person that immediately
thereafter would be a Restricted Subsidiary shall be counted as a Restricted
Payment. In addition, if any Person in which an Investment is made, which
Investment constitutes a Restricted Payment when made, thereafter becomes a
Restricted Subsidiary, all such Investments previously made in such Person shall
no longer be counted as Restricted Payments for purposes of calculating the
aggregate amount of Restricted Payments pursuant to clause (c) of the third
preceding paragraph or the aggregate amount of Investments pursuant to clause
(i) of the immediately preceding paragraph, in each case to the extent such
Investments would otherwise be so counted.
 
     For purposes of clause (c)(3) above, the net proceeds received by the
Company from the issuance or sale of its Capital Stock either upon the
conversion of, or exchange for, Debt of the Company or any Restricted Subsidiary
shall be deemed to be an amount equal to (i) the sum of (a) the principal amount
or accreted value (whichever is less) of such Debt on the date of such
conversion or exchange and (b) the additional cash consideration, if any,
received by the Company upon such conversion or exchange, less any payment on
account of fractional shares, minus (ii) all expenses incurred in connection
with such issuance or sale. In addition, for purposes of clause (c)(3) above,
the net proceeds received by the Company from the issuance or sale of its
Capital Stock upon the exercise of any options or warrants of the Company or any
Restricted Subsidiary shall be deemed to be an amount equal to (x) the
additional cash consideration, if any, received by the Company upon such
exercise, minus (y) all expenses incurred in connection with such issuance or
sale.
 
     For purposes of this "Limitation on Restricted Payments" covenant, if a
particular Restricted Payment involves a noncash payment, including a
distribution of assets, then such Restricted Payment shall be deemed
 
                                       64
<PAGE>   72
 
to be an amount equal to the cash portion of such Restricted Payment, if any,
plus an amount equal to the fair market value of the non-cash portion of such
Restricted Payment, as determined by the Board of Directors (whose good faith
determination shall be conclusive and evidenced by a Board Resolution).
 
  Restricted Subsidiaries
 
     The Company shall not designate any Restricted Subsidiary as an
Unrestricted Subsidiary, and shall not itself, and shall not permit any
Restricted Subsidiary to, sell, convey, transfer, or otherwise dispose of any
assets, other than in the ordinary course of business, to any Unrestricted
Subsidiary or any Person that becomes an Unrestricted Subsidiary as part of such
transaction, unless, after giving effect to any such action, the assets (not
including any assets so sold, conveyed, transferred, or otherwise disposed of,
other than in the ordinary course of business, to any Unrestricted Subsidiary or
any Person that becomes an Unrestricted Subsidiary as part of such transaction)
and business of the Company and its remaining Restricted Subsidiaries generated
at least 90% of Digital Mobile-SMR Operating Cash Flow in the fiscal quarter of
the Company most recently completed prior to the date of such action.
 
     The Board of Directors may designate any existing Unrestricted Subsidiary
or any Person that is about to become a Subsidiary of the Company as a
Restricted Subsidiary if, after giving effect to such action (and, if such
designation is made in connection with the acquisition of a Person or an
operating business that is about to become a Subsidiary of the Company, after
giving effect to all terms of such acquisition) on a pro forma basis, on the
date of such action, the Debt, if any, of such Unrestricted Subsidiary or Person
outstanding immediately prior to such designation would have been permitted to
be Incurred (and shall be deemed to have been Incurred) for all purposes of the
Indenture.
 
     Subject to the second preceding paragraph and compliance with the
"Limitation on Restricted Payments" covenant, the Board of Directors may
designate any Restricted Subsidiary as an Unrestricted Subsidiary.
 
     The designation by the Board of Directors of a Restricted Subsidiary as an
Unrestricted Subsidiary shall, for all purposes of the "Limitation on Restricted
Payments" covenant (including clause (b) thereof), be deemed to be a Restricted
Payment of an amount equal to the fair market value of the Company's ownership
interest in such Subsidiary (including, without duplication, such indirect
ownership interest in all Subsidiaries of such Subsidiary), as determined by the
Board of Directors in good faith and evidenced by a Board Resolution.
 
     Notwithstanding the foregoing provisions of this "Restricted Subsidiaries"
covenant, the Board of Directors may not designate a Subsidiary of the Company
to be an Unrestricted Subsidiary if, after such designation, (i) the Company or
any of its other Restricted Subsidiaries (a) provides credit support for, or a
Guarantee of, any Debt of such Subsidiary (including any undertaking, agreement,
or instrument evidencing such Debt) or (b) is directly or indirectly liable for
any Debt of such Subsidiary, (ii) a default with respect to any Debt of such
Subsidiary (including any right which the holders thereof may have to take
enforcement action against such Subsidiary) would permit (upon notice, lapse of
time or both) any holder of any other Debt of the Company or any Restricted
Subsidiary to declare a default on such other Debt or cause the payment thereof
to be accelerated or payable prior to its final scheduled maturity or (iii) such
Subsidiary owns any Capital Stock of, or owns or holds any Lien on any property
of, any Restricted Subsidiary which is not a Subsidiary of the Subsidiary to be
so designated.
 
     The Board of Directors, from time to time, may designate any Person that is
about to become a Subsidiary of the Company as an Unrestricted Subsidiary, and
may designate any newly-created Subsidiary as an Unrestricted Subsidiary, if at
the time such Subsidiary is created it contains no assets (other than such de
minimis amount of assets then required by law for the formation of corporations)
and no Debt. Subsidiaries of the Company that are not designated by the Board of
Directors as Restricted or Unrestricted Subsidiaries shall be deemed to be
Restricted Subsidiaries. Notwithstanding any provisions of this "Restricted
Subsidiaries" covenant, all Subsidiaries of an Unrestricted Subsidiary shall be
Unrestricted Subsidiaries. The Board of Directors shall not change the
designation of a Subsidiary of the Company more than twice in any period of five
years.

<PAGE>   73
 
  Transactions with Affiliates
 
     The Company shall not, and shall not permit any Restricted Subsidiary to,
directly or indirectly, enter into any transaction (including the purchase,
sale, lease, or exchange of any property or the rendering of any service) or
series of related transactions with any Affiliate of the Company on terms that
are less favorable to the Company or such Restricted Subsidiary, as the case may
be, than those that might be obtained at the time of such transaction from a
Person that is not such an Affiliate; provided, however, that this "Transactions
with Affiliates" covenant shall not limit, or be applicable to, (i) any
transaction between Unrestricted Subsidiaries not involving the Company or any
Restricted Subsidiary, (ii) any transaction between the Company and any
Restricted Subsidiary or between Restricted Subsidiaries, or (iii) any Permitted
Transactions. In addition, any transaction or series of related transactions,
other than Permitted Transactions, between the Company or any Restricted
Subsidiary and any Affiliate of the Company (other than a Restricted Subsidiary)
involving an aggregate consideration of $5 million or more must be approved in
good faith by a majority of the Company's Disinterested Directors (of which
there must be at least one) and evidenced by a Board Resolution. For purposes of
this "Transactions with Affiliates" covenant, any transaction or series of
related transactions between the Company or any Restricted Subsidiary and an
Affiliate of the Company that is approved by a majority of the Disinterested
Directors (of which there must be at least one) and evidenced by a Board
Resolution shall be deemed to be on terms as favorable as those that might be
obtained at the time of such transaction (or series of transactions) from a
Person that is not such an Affiliate and thus shall be permitted under this
"Transactions with Affiliates" covenant.
 
  Activities of the Company and Restricted Subsidiaries
 
     The Company shall not, and shall not permit any Restricted Subsidiary to,
engage in any business other than the telecommunications business and related
activities and services, including such businesses, activities, and services in
which the Company and the Restricted Subsidiaries were engaged on the Closing
Date.
 
  Provision of Financial Information
 
     Whether or not the Company is subject to Section 13(a) or 15(d) of the
Exchange Act, or any successor provision thereto, the Company shall file with
the Commission the annual reports, quarterly reports, and other documents which
the Company would have been required to file with the Commission pursuant to
such Section 13(a) or 15(d) or any successor provision thereto if the Company
were subject thereto, such documents to be filed with the Commission on or prior
to the respective dates (the "Required Filing Dates") by which the Company would
have been required to file them. The Company shall also in any event (i) within
15 days of each Required Filing Date (a) transmit by mail to all Holders, as
their names and addresses appear in the Security Register, without cost to such
Holders, and (b) file with the Trustee copies of the annual reports, quarterly
reports and other documents which the Company would have been required to file
with the Commission pursuant to Section 13(a) or 15(d) of the Exchange Act or
any successor provisions thereto if the Company were subject thereto and (ii) if
filing such documents by the Company with the Commission is not permitted under
the Exchange Act, promptly upon written request supply copies of such documents
to any prospective holder. The Trustee's receipt of such reports, information,
and documents shall not constitute constructive notice of any information
contained therein or determinable from information contained therein.
 
  Merger, Sale of Assets, Etc.
 
     The Company (x) shall not, in any transaction or series of related
transactions, merge or consolidate with or into, or sell, assign, convey,
transfer, lease, or otherwise dispose of its properties and assets substantially
as an entirety to, any Person, and (y) shall not permit any of its Restricted
Subsidiaries to enter into any such transaction or series of transactions if
such transaction or series of transactions, in the aggregate, would result in a
sale, assignment, conveyance, transfer, lease, or other disposition of the
properties and assets of the Company and its Restricted Subsidiaries, taken as a
whole, substantially as an entirety to any Person, unless, in each case (x) or
(y), at the time and after giving effect thereto (i) either: (a) if the
transaction or series of transactions is a consolidation of the Company with or
a merger of the Company with or into any other Person, the Company shall be the
surviving Person of such merger or consolidation, or (b) the Person formed by
any
 
                                       66
<PAGE>   74
 
consolidation with or merger with or into the Company, or to which the
properties and assets of the Company or the Company and its Restricted
Subsidiaries, taken as a whole, as the case may be, substantially as an entirety
are sold, assigned, conveyed, leased, or otherwise transferred (any such
surviving Person or transferee Person referred to in this clause (b) being the
"Surviving Entity"), shall be a corporation, partnership, or trust organized and
existing under the laws of the United States of America, any state thereof, or
the District of Columbia and shall expressly assume by a supplemental indenture
executed and delivered to the Trustee, in form satisfactory to the Trustee, all
the obligations of the Company under the Notes and the Indenture and, in each
case, the Indenture, as so supplemented, shall remain in full force and effect,
and (ii) immediately before and immediately after giving effect to such
transaction or series of transactions on a pro forma basis (including any Debt
Incurred or anticipated to be Incurred in connection with or in respect of such
transaction or series of transactions), no Default or Event of Default shall
have occurred and be continuing, and (iii) the Consolidated Net Worth of the
Company or the Surviving Entity, as the case may be, shall be equal to or
greater than that of the Company immediately prior to such transaction or series
of transactions; provided, however, that the foregoing requirements shall not
apply to any transaction or series of transactions involving the sale,
assignment, conveyance, transfer, lease, or other disposition of the properties
and assets by any Restricted Subsidiary to any other Restricted Subsidiary, or
the merger or consolidation of any Restricted Subsidiary with or into any other
Restricted Subsidiary.
 
     In connection with any consolidation, merger, sale, assignment, conveyance,
transfer, lease, or other disposition contemplated by the foregoing provisions,
the Company shall deliver, or cause to be delivered, to the Trustee, in form and
substance reasonably satisfactory to the Trustee, an Officers' Certificate
stating that such consolidation, merger, sale, assignment, conveyance, transfer,
lease, or other disposition and the supplemental indenture in respect thereof
(required under clause (i)(b) of the preceding paragraph) comply with the
requirements of the Indenture and an opinion of counsel stating that the
conditions of the Indenture have been complied with. Each such Officers'
Certificate shall set forth the manner of determination of the Consolidated Net
Worth in accordance with clause (iii) of the preceding paragraph.
 
     For all purposes of the Indenture and the Notes (including the provisions
described in the two immediately preceding paragraphs and the "Limitation on
Consolidated Debt" and "Restricted Subsidiaries" covenants), Subsidiaries of any
Surviving Entity will, upon such transaction or series of transactions, become
Restricted Subsidiaries or Unrestricted Subsidiaries as provided pursuant to the
"Restricted Subsidiaries" covenant, and all Debt of the Surviving Entity and its
Subsidiaries that was not Debt of the Company and its Subsidiaries immediately
prior to such transaction or series of transactions shall be deemed to have been
Incurred upon such transaction or series of transactions.
 
EVENTS OF DEFAULT
 
     The following constitute Events of Default under the Indenture: (i) failure
to pay principal of (or premium, if any, on) any Note when due; (ii) failure to
pay any interest on any Note when due, continued for 30 days; (iii) default in
the payment of principal of, and premium and interest, if any, on Notes required
to be purchased pursuant to an Offer to Purchase as described under "Change of
Control" when due and payable, or failure to make an Offer to Purchase as
required thereunder; (iv) failure to perform or comply with the provisions
described under "Merger, Sale of Assets, Etc."; (v) failure to perform any other
covenant or agreement of the Company under the Indenture or in the Notes
continued for 60 days after written notice to the Company by the Trustee or
Holders of at least 25% in aggregate principal amount of the outstanding Notes;
(vi) failure to pay when due (subject to any applicable grace period) the
principal of, or acceleration of, any Debt of the Company or any Restricted
Subsidiary having an outstanding principal amount of at least $25,000,000,
individually or in the aggregate; (vii) the rendering of a final judgment or
judgments against the Company or any Restricted Subsidiary in an amount in
excess of $25,000,000 which remains undischarged or unstayed for a period of 60
days after the date on which the right to appeal has expired; and (viii) certain
events of bankruptcy, insolvency, or reorganization affecting the Company or any
Restricted Subsidiary.
 
     If an Event of Default (other than an Event of Default described in clause
(viii) above) shall occur and be continuing, either the Trustee or the Holders
of at least 25% in aggregate principal amount at Stated Maturity of the
outstanding Notes may accelerate the Default Amount of all Notes; provided
however that
 
                                       67
<PAGE>   75
 
after such acceleration, but before a judgment or decree based on acceleration,
the Holders of a majority in aggregate principal amount at Stated Maturity of
outstanding Notes may, under certain circumstances, rescind and annul such
acceleration if all Events of Default, other than the nonpayment of the Default
Amount of the Notes, have been cured or waived as provided in the Indenture. If
an Event of Default specified in clause (viii) above occurs, the Default Amount
and any accrued interest on the outstanding Notes will ipso facto become
immediately due and payable without any declaration or other act on the part of
the Trustee or any Holder. For information as to waiver of defaults, see
"Modification and Waiver."
 
     Subject to the provisions of the Indenture relating to the duties of the
Trustee in case an Event of Default shall occur and be continuing, the Trustee
will be under no obligation to exercise any of its rights or powers under the
Indenture at the request or direction of any of the Holders, unless such Holders
shall have offered to the Trustee reasonable security or indemnity. Subject to
such provisions for the indemnification of the Trustee, the Holders of a
majority in aggregate principal amount at Stated Maturity of the outstanding
Notes will have the right to direct the time, method, and place of conducting
any proceeding for any remedy available to the Trustee or exercising any trust
or power conferred on the Trustee.
 
     No Holder of any Notes will have any right to institute any proceeding with
respect to the Indenture or for any remedy thereunder, unless such Holder shall
have previously given to the Trustee written notice of a continuing Event of
Default and unless also the Holders of at least 25% in aggregate principal
amount at Stated Maturity of the outstanding Notes shall have made written
request, and offered reasonable security or indemnity, to the Trustee to
institute such proceeding as trustee, and the Trustee shall not have received
from the Holders of a majority in aggregate principal amount at Stated Maturity
of the outstanding Notes a direction inconsistent with such request and shall
have failed to institute such proceeding within 60 days. However, such
limitations do not apply to a suit instituted by a Holder of a Note for
enforcement of payment of the principal of, premium and interest, if any, on
such Note on or after the respective due dates expressed in such Note.
 
     The Company will be required to furnish to the Trustee annually a statement
as to the performance by it of certain of its obligations under the Indenture
and as to any default in such performance.
 
DEFEASANCE AND COVENANT DEFEASANCE
 
     The Company may elect, at its option at any time, to have the provisions of
the Indenture relating to defeasance and discharge of indebtedness or the
provisions relating to defeasance of certain restrictive covenants in the
Indenture, applied to the outstanding Notes (as a whole and not in part).
 
     Defeasance and Discharge.  The Indenture provides that, upon the Company's
exercise of its option to have the provisions relating to defeasance and
discharge applied to the outstanding Notes, the Company will be discharged from
all its obligations with respect to the Notes (except for certain obligations to
exchange or register the transfer of Notes, to replace stolen, lost, or
mutilated Notes, to maintain paying agencies, and to hold moneys for payment in
trust) upon the deposit in trust for the benefit of the Holders of such Notes of
money or U.S. Government Obligations, or both, which, through the payment of
principal and interest in respect thereof in accordance with their terms, will
provide money in an amount sufficient to pay the principal of and any
installment of interest on such Notes on the respective Stated Maturities
thereof in accordance with the terms of the Indenture and the Notes. Such
defeasance or discharge may occur only if, among other things, the Company has
delivered to the Trustee an opinion of counsel to the effect that the Company
has received from, or there has been published by, the Internal Revenue Service
(the "IRS") a ruling, or there has been a change in tax law, in either case to
the effect that Holders of such Notes will not recognize gain or loss for
Federal income tax purposes as a result of such deposit, defeasance and
discharge and will be subject to Federal income tax on the same amount, in the
same manner, and at the same times as would have been the case if such deposit,
defeasance and discharge were not to occur.
 
     Defeasance of Certain Covenants.  The Indenture provides that, upon the
Company's exercise of its option to defease certain restrictive covenants
applied to the outstanding Notes, the Company may omit to comply with certain
restrictive covenants, including those described under "Covenants" and clause
(iii) under "Merger, Sale of Assets, Etc.," and the occurrence of certain Events
of Default, which are described above in
 
                                       68
<PAGE>   76
 
clause (iv) (with respect to such clause (iii)), clause (v) (with respect to
such restrictive covenants), clause (vi) and clause (vii) under "Events of
Default," will be deemed not to be or result in an Event of Default, in each
case with respect to such Notes. The Company, in order to exercise such option,
will be required to deposit, in trust for the benefit of the Holders of such
Notes, money or U.S. Government Obligations, or both, which, through the payment
of principal and interest in respect thereof in accordance with their terms,
will provide money in an amount sufficient to pay the principal of and any
installment of interest on such Notes on the respective Stated Maturities
thereof in accordance with the terms of the Indenture and the Notes. The Company
will also be required, among other things, to deliver to the Trustee an opinion
of counsel to the effect that Holders of such Notes will not recognize gain or
loss for Federal income tax purposes as a result of such deposit and defeasance
of certain obligations and will be subject to Federal income tax on the same
amount, in the same manner, and at the same times as would have been the case if
such deposit and defeasance were not to occur. In the event the Company
exercised this option with respect to the outstanding Notes and such Notes were
declared due and payable prior to their Stated Maturity because of the
occurrence of any Event of Default or become payable on any redemption date at
the option of the Company, the amount of money and U.S. Government Obligations
so deposited in trust would be sufficient to pay amounts due on such Notes at
the time of their respective Stated Maturities, but may not be sufficient to pay
amounts due on such Notes upon such acceleration or redemption. In such case,
the Company would remain liable for such payments.
 
MODIFICATION AND WAIVER
 
     Modifications and amendments of the Indenture may be made by the Company
and the Trustee with the consent of the Holders of not less than a majority in
aggregate principal amount at Stated Maturity of the outstanding Notes;
provided, however, that no such modification or amendment may, without the
consent of each Holder affected thereby, (i) change the Stated Maturity of the
principal of, or any installment of interest on, any Note, (ii) reduce the
principal amount of, premium, if any, or interest on, any Note, (iii) change the
place or currency of payment of principal or premium, if any, or interest on,
any Note, (iv) impair the right to institute suit for the enforcement of any
payment on or after the Stated Maturity (or, in the case of a redemption, on or
after the Redemption Date) of any Note, (v) reduce the above stated percentage
of outstanding Notes the consent of whose Holders is necessary to modify or
amend the Indenture, (vi) waive a default in the payment of principal of,
premium, if any, or interest on, the Notes, (vii) reduce the percentage of
aggregate principal amount of outstanding Notes the consent of whose Holders is
necessary for waiver of compliance with certain provisions of the Indenture or
for waiver of certain defaults, (viii) modify any provisions of the Indenture
relating to the calculation of Accreted Value of the Notes or (ix) following the
mailing of an Offer to Purchase, modify the provisions of the Indenture with
respect to such Offer to Purchase in a manner adverse to such Holders.
 
NO PERSONAL LIABILITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS, DIRECTORS OR
EMPLOYEES
 
     The Indenture provides that no recourse for the payment of the principal
of, premium, if any, or interest on, any of the Notes, or for any claim based
thereon or otherwise in respect thereof, and no recourse under or upon any
obligation, covenant or agreement of the Company contained in the Indenture or
in any of the Notes, or because of the creation of any Debt represented thereby,
shall be had against any incorporator or past, present or future stockholder,
officer, director, employee, or controlling person of the Company. Each Holder,
by accepting such Notes, waives and releases all such liability.
 
CONCERNING THE TRUSTEE
 
     The Indenture provides that, except during the continuance of an Event of
Default, the Trustee performs only such duties as are specifically set forth in
the Indenture. If an Event of Default has occurred and is continuing, the
Trustee will exercise those rights and powers vested in it under such Indenture
and use the same degree of care and skill in its exercise of such rights and
powers as a prudent person would exercise under the circumstances in the conduct
of such person's own affairs.
 
     The Indenture and provisions of the Trust Indenture Act, incorporated by
reference in the Indenture, contain limitations on the rights of the Trustee
thereunder, should it become a creditor of the Company, to
 
                                       69
<PAGE>   77
 
obtain payment of claims in certain cases or to realize on certain property
received by it in respect of any such claims, as security or otherwise. The
Trustee is permitted to engage in other transactions; provided, however, that if
it acquires any conflicting interest, it must eliminate such conflict or resign.
 
BOOK-ENTRY; DELIVERY AND FORM
 
     The Exchange Senior Notes will initially be issued in the form of one
global certificate (the "Global Exchange Senior Note"). The Global Exchange
Senior Note will be deposited on the date of the consummation of the Exchange
Offer (the "Exchange Offer Closing Date") with or on behalf of DTC and
registered in the name of DTC or its nominee.
 
     The Company understands that DTC is a limited purpose trust company
organized under the laws of the State of New York, a "banking organization"
within the meaning of New York Banking Law, a member of the Federal Reserve
System, a "clearing corporation" within the meaning of the Uniform Commercial
Code, and a "Clearing Agency" registered pursuant to the provisions of Section
17A of the Exchange Act. DTC was created to hold securities for its participants
and facilitate the clearance and settlement of securities transactions between
participants through electronic book-entry changes in accounts of its
participants, thereby eliminating the need for physical movement of
certificates. Participants include securities brokers and dealers, banks, trust
companies, and clearing corporations and may include certain other
organizations. Indirect access to the DTC system is available to others such as
banks, brokers, dealers, and trust companies that clear through or maintain a
custodial relationship with a participant, either directly or indirectly
("indirect participants").
 
     So long as DTC, or its nominee, is the registered owner or holder of the
Global Exchange Senior Note, DTC or such nominee, as the case may be, will be
considered the sole owner or holder of the Exchange Senior Notes represented by
such Global Exchange Senior Note for all purposes under the Indenture. The
Company understands that pursuant to procedures established by DTC (i) upon
deposit of the Global Exchange Senior Note, DTC will credit the accounts of
participants exchanging the Private Notes for Exchange Senior Notes in amounts
proportionate to the respective beneficial interests in the principal amount of
the Global Exchange Senior Note and (ii) ownership of the Exchange Senior Notes
evidenced by the Global Exchange Senior Note will be shown on, and the transfer
of ownership thereof will be effected only through, records maintained by DTC
(with respect to the interests of DTC's participants), DTC's participants and
DTC's indirect participants. No beneficial owner of an interest in the Global
Exchange Senior Note will be able to transfer that interest except in accordance
with DTC's applicable procedures, in addition to those provided for under the
Indenture.
 
     Payments made with respect to the Global Exchange Senior Note will be made
to DTC or its nominee, as the case may be, as the registered owner thereof. The
Company will have no responsibility or liability for any aspect of the records
relating to or payments made on account of beneficial ownership interests in the
Global Exchange Senior Note or for maintaining, supervising, or reviewing any
records relating to such beneficial ownership interests.
 
     The Company expects that DTC or its nominee, upon receipt of any payments
made with respect to the Global Exchange Senior Note, will credit participants'
accounts with payments in amounts proportionate to their respective beneficial
interests in the amount of such Global Exchange Senior Note as shown on the
records of DTC or its nominee. The Company also expects that payments by
participants to owners of beneficial interests in such Global Exchange Senior
Note held through such participants will be governed by standing instructions
and customary practices, as is now the case with securities held for the
accounts of customers registered in the names of nominees for such customers.
Such payments will be the responsibility of such participants.
 
     Transfers between participants in DTC will be effected in the ordinary way
in accordance with DTC rules and will be settled in same-day funds.
 
     Although DTC is expected to follow the foregoing procedures in order to
facilitate transfers of interests in the Global Exchange Senior Note among
participants of DTC, it is under no obligation to perform or continue
 
                                       70
<PAGE>   78
 
to perform such procedures, and such procedures may be discontinued at any time.
The Company will have no responsibility for the performance by DTC or its
respective participants or indirect participants of its respective obligations
under the rules and procedures governing their operations.
 
CERTIFICATED NOTES
 
     If DTC is at any time unwilling or unable to continue as a depositary for
the Global Exchange Senior Note and a successor depositary is not appointed by
the Company within 90 days, the Company will issue a physical certificate for
such Notes ("Certificated Notes") in exchange for the Global Exchange Senior
Note. In addition, if there is an Event of Default under the Notes, DTC may
exchange the Global Exchange Senior Note for Certificated Notes and distribute
such Certificated Notes to its participants. Finally, beneficial owners whose
interests are represented by the Global Exchange Senior Note may request a
physical certificate.

            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS
 
     The following discussion is a summary of the principal United States
Federal income tax consequences of the Exchange Offer and the purchase,
ownership, and disposition of the Notes and does not purport to be a complete
analysis of all of the potential tax effects of such purchase, ownership, or
disposition. This summary deals only with Notes held as "capital assets" within
the meaning of Section 1221 of the Code by U.S. Holders (as defined herein). It
does not address all aspects of the United States Federal income tax
consequences of purchasing, holding, or disposing of the Notes that may be
relevant to a particular investor in the context of such investor's individual
investment circumstances or to investors in special situations, such as life
insurance companies, financial institutions, tax-exempt organizations, traders
or dealers in securities and currencies, persons holding Notes as a part of a
hedging or conversion transaction or a straddle, U.S. Holders whose "functional
currency" is not the United States dollar, or Non-U.S. Holders (as defined
herein). This summary also does not discuss tax consequences under state, local,
or foreign tax laws. Persons considering the purchase of the Notes should
consult their own tax advisors concerning the application of and the potential
changes in United States Federal income tax laws, as well as the laws of any
state, local, or foreign taxing jurisdiction, to their particular situation.
Furthermore, the discussion below is based upon the provisions of the Code and
existing and proposed Treasury regulations, administrative rulings, and judicial
decisions thereunder as of the date hereof, and such authorities may be
repealed, revoked, or modified, possibly with retroactive effect, so as to
result in United States Federal income tax consequences different from those
discussed below.
 
     As used herein, a "U.S. Holder" means a beneficial owner that is a citizen
or resident of the United States, a corporation, partnership, or other entity
created or organized in or under the laws of the United States or any political
subdivision thereof, or an estate the income of which is subject to United
States Federal income taxation regardless of its source, or a trust over which a
court within the United States is able to exercise primary supervision and as to
which one or more United States fiduciaries have the authority to control all
substantial decisions. An individual may, subject to certain exceptions, be
deemed to be a resident (as opposed to a non-resident alien) of the United
States for certain purposes by virtue of being present in the United States on
at least 31 days in the calendar year and for an aggregate of at least 183 days
during a three-year period ending in the current calendar year (counting for
such purposes all of the days present in the current year, one-third of the days
present in the immediately preceding year, and one-sixth of the days present in
the second preceding year). A "Non-U.S. Holder" is a holder that is not a U.S.
Holder.
 
     ALL PROSPECTIVE INVESTORS ARE ADVISED TO CONSULT THEIR OWN TAX ADVISORS
REGARDING THE FEDERAL, STATE, LOCAL, AND FOREIGN TAX CONSEQUENCES OF THE
OWNERSHIP AND DISPOSITION OF THE NOTES.
 
THE EXCHANGE OF PRIVATE NOTES FOR EXCHANGE SENIOR NOTES
 
     The exchange of Private Notes for Exchange Senior Notes should not be
treated as a taxable transaction for United States Federal income tax purposes
because the Exchange Senior Notes should not be considered to differ materially
in kind or extent from the Private Notes. Rather, the Exchange Senior Notes
received by a U.S. Holder of Private Notes should be treated as a continuation
of the Private Notes in the hands of such U.S. Holder. As a result, there should
be no material Federal income tax consequences to U.S. Holders exchanging
Private Notes for Exchange Senior Notes.
 
ORIGINAL ISSUE DISCOUNT
 
     Because the Private Notes were issued at a discount from their "stated
redemption price at maturity," the Exchange Senior Notes will have original
issue discount ("OID") for Federal income tax purposes and U.S. Holders of
Exchange Senior Notes will be subject to special tax accounting rules, as
described in greater detail below. U.S. Holders of Exchange Senior Notes should
be aware that they generally must include OID in gross income for Federal income
tax purposes on an annual basis under a constant yield accrual method regardless
of their method of accounting. As a result, U.S. Holders will include OID in
income in advance of the receipt of cash attributable to such income. However,
U.S. Holders of Notes generally will not be required
 
                                       72
<PAGE>   80
 
to include separately in income cash payments received on such notes, even if
denominated as interest, to the extent such payments do not constitute qualified
stated interest (as defined herein).
 
     The amount of OID, if any, on a debt instrument is the excess of its
"stated redemption price at maturity" over its "issue price," subject to a
statutorily defined de minimis exception. The "stated redemption price at
maturity" of a debt instrument is the sum of its principal amount plus all other
payments required thereunder, other than payments of "qualified stated
interest." For this purpose, "qualified stated interest" generally means stated
interest that is unconditionally payable in cash or in property (other than the
debt instruments of the issuer), at least annually at a single fixed rate during
the entire term of the debt instrument that appropriately takes into account the
length of intervals between payments. Subject to the discussion set forth below
in respect of Nextel's option to redeem the Notes at a percentage of par plus
accrued interest after October 31, 2002, the interest payments on the Notes will
not constitute qualified stated interest, and thus will be included along with
principal in the stated redemption price at maturity of the Notes. As a result,
subject to such discussion, each Note will bear OID in an amount equal to the
excess of (i) the sum of its principal amount and all stated interest payments,
over (ii) its issue price. Because the Exchange Senior Notes should be treated
as a continuation of the Private Notes, the issue price of the Exchange Senior
Notes will be the first price to the public (excluding bond houses and brokers)
at which a substantial amount of Private Notes was sold.
 
     The amount of OID includible in income by an initial U.S. Holder of a Note
is the sum of the "daily portions" of OID with respect to the Note for each day
during the taxable year or portion of the taxable year in which such U.S. Holder
holds such note ("accrued OID"). The daily portion is determined by allocating
to each day in any "accrual period" a pro rata portion of the OID allocable to
that accrual period. The "accrual period" for a Note may be of any length and
may vary in length over the term of the OID note, provided that each accrual
period is no longer than one year and each scheduled payment of principal or
interest occurs on the first day or final day of an accrual period. The amount
of OID allocable to any accrual period is an amount equal to the excess, if any,
of (i) the product of the Note's adjusted issue price at the beginning of such
accrual period and its yield to maturity (determined on the basis of compounding
at the close of each accrual period and properly adjusted for the length of the
accrual period) over (ii) the sum of any qualified stated interest allocable to
the accrual period. OID allocable to a final accrual period is the difference
between the amount payable at maturity (other than a payment of qualified stated
interest) and the adjusted issue price at the beginning of the final accrual
period. Special rules will apply for calculating OID for an initial short
accrual period. The "adjusted issue price" of a Note at the beginning of any
accrual period is equal to its issue price increased by the accrued OID for each
prior accrual period (determined without regard to the amortization of any
acquisition bond premium, as described below) and reduced by any payments made
on such note (other than qualified stated interest) on or before the first day
of the accrual period.
 
     The Notes may be redeemed prior to their stated maturity at the option of
Nextel. For purposes of computing the yield of such instruments, Nextel will be
deemed to exercise or not exercise its option to redeem the Notes in a manner
that minimizes the yield on the Notes. It is not anticipated that Nextel's
ability to redeem prior to stated maturity would affect the yield of a Note.
 
OPTIONAL REDEMPTION
 
     Nextel's option to redeem the Notes at any time on or after October 31,
2002 at a percentage of par plus accrued but unpaid interest would be treated as
a "call option" within the meaning of the income tax regulations. As a result,
Nextel would be presumed to exercise its option to redeem the Notes if, by
utilizing the date of exercise of the call option as the maturity date and the
amount for which the Notes could be redeemed in accordance with the terms of the
redemption feature, plus interest which, under the terms of the Notes, would
have been paid as of such redemption date, as the stated redemption price at
maturity, the yield on the Notes would be lower than such yield would be if the
option were not exercised.
 
     If Nextel's option to redeem the Notes were presumed exercised on a given
date (the "Presumed Exercise Date"), the Notes would bear OID in an amount equal
to the excess of the amount for which the Notes could be redeemed on the
Presumed Exercise Date (the "Redemption Amount") plus interest which,
 
                                       73
<PAGE>   81
 
under the terms of the Notes, would have been paid as of such redemption date,
over their issue price, and for purposes of calculating the current inclusion of
such OID, their yield would be computed on their issue date by treating the
Presumed Exercise Date as the maturity date of the Notes and the Redemption
Amount plus interest which, under the terms of the Notes, would have been paid
as of such redemption date, as their stated redemption price at maturity. If
Nextel's option to redeem the Notes were presumed exercised but were not
exercised in fact on the Presumed Exercise Date, the yield and maturity of the
Notes, solely for purposes of the accrual of OID, would be redetermined by
treating the Notes as if the option were exercised and new debt instruments were
issued on the Presumed Exercise Date for an amount of cash equal to the Notes'
adjusted issue price on the Presumed Exercise Date. In such case, although the
matter is not clear, it appears that any payment of stated interest due under
the Notes after the Presumed Exercise Date would represent qualified stated
interest (rather than OID). Qualified stated interest is includible by a U.S.
Holder as interest income in accordance with such U.S. Holder's regular method
of accounting.
 
     In addition to the optional redemption described above, on or prior to
October 31, 2000 Nextel will have the right to redeem up to 33 1/3% in aggregate
Accreted Value of the outstanding Notes out of the net cash proceeds of any one
or more sales of at least $125,000,000 of its Capital Stock. Furthermore,
holders will have the right to tender Notes to Nextel for redemption should
Nextel experience a Change of Control and be required to make an Offer to
Purchase the Notes. Such optional redemption rights should not affect, and will
not be treated by Nextel as affecting, the determination of the yield or
maturity of the Notes. If Nextel exercises its right to redeem the Notes using
the proceeds of a sale of Common Stock, the United States Federal income tax
treatment of the redemption should be governed by the rules for dispositions
generally. See "-- Redemption, Sale or Exchange of Notes" below.
 
MARKET DISCOUNT ON NOTES
 
     If a U.S. Holder acquires a Note for an amount less than its revised issue
price, the amount of the difference will be treated as "market discount" for
United States Federal income tax purposes, unless such difference is less than a
specified de minimis amount. The Code provides that, for these purposes, the
revised issue price of a Note generally equals its issue price, increased by the
amount of any OID that has accrued on the Note. Under the market discount rules,
a U.S. Holder will be required to treat any principal payment on a Note or any
gain on the sale, exchange, retirement or other disposition of a Note as
ordinary income to the extent of the market discount which has not previously
been included in income and is treated as having accrued on such Note at the
time of such payment or disposition. In addition, the U.S. Holder may be
required to defer, until the maturity of the Note or its earlier disposition in
a taxable transaction, the deduction of all or a portion of the interest expense
on any indebtedness incurred or continued to purchase or carry such Note.
 
     Any market discount will be considered to accrue ratably during the period
from the date of acquisition to the maturity date of the Note, unless the U.S.
Holder elects to accrue on a constant interest method. A U.S. Holder of a Note
may elect to include market discount in income currently as it accrues (on
either a ratable or constant interest method), in which case the rule described
above regarding deferral of interest deductions will not apply. This election to
include market discount in income currently, once made, applies to all market
discount obligations acquired on or after the first taxable year to which the
election applies and may not be revoked without the consent of the IRS.
 
ACQUISITION PREMIUM; AMORTIZABLE BOND PREMIUM
 
     A U.S. Holder that is treated as acquiring a Note for an amount that is
greater than its adjusted issue price but equal to or less than the sum of all
amounts payable on the Note after the purchase date, other than qualified stated
interest, will be considered to have purchased such Note at an "acquisition
premium." Under the acquisition premium rules, the amount of OID, if any, which
such U.S. Holder must include in its gross income with respect to such Note for
any taxable year will be reduced by the portion of such acquisition premium
properly allocable to such year.
 
                                       74
<PAGE>   82
 
     If immediately after the time a subsequent U.S. Holder acquires a Note, the
U.S. Holder's tax basis in any such Note exceeds the sum of all amounts payable
on the Note after the exchange date or purchase date, other than qualified
stated interest, such excess may constitute "premium" and such U.S. Holder will
not be required to include any OID in income. A U.S. Holder generally may elect
to amortize bond premium over the remaining term of the Note on a constant yield
method. The amount amortized in any year will be treated as a reduction of the
U.S. Holder's interest income, including OID, from the Note.
 
     Bond premium on a Note held by a U.S. Holder that does not make such an
election will decrease the gain or increase the loss otherwise recognized on
disposition of the Note. The election to amortize bond premium on a constant
yield method, once made, applies to all debt obligations held or subsequently
acquired by the electing U.S. Holder on or after the first day of the first
taxable year to which the election applies and may not be revoked without the
consent of the IRS.
 
REDEMPTION, SALE OR EXCHANGE OF NOTES
 
     In general, upon the redemption, sale, exchange, or retirement of a Note, a
U.S. Holder will recognize gain or loss equal to the difference between the
amount realized upon the redemption, sale, exchange, or retirement (less any
accrued qualified stated interest, not previously taken into account, which will
be taxable as such) and the adjusted tax basis of the Note. The adjusted tax
basis of a U.S. Holder in a Note will, in general, initially equal the cost of
the Note to such U.S. Holder, increased by OID and market discount previously
included in income by the U.S. Holder and reduced by any amortized premium and
any cash payments on the Note other than qualified stated interest received by
such U.S. Holder. Except with respect to accrued market discount, such gain or
loss will be either long-term or short-term capital gain depending on the U.S.
Holder's holding period for the Note at the time of redemption, sale, exchange,
or retirement of the Note.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
     In general, information reporting requirements will apply to certain
payments of principal, interest, OID, and premium and to the proceeds of sales
of Notes made to U.S. Holders other than certain exempt recipients (such as
corporations). A 31% backup withholding tax will apply to such payments if the
U.S. Holder fails to provide a correct taxpayer identification number or
certification of exempt status or, with respect to certain payments, the U.S.
Holder fails to report in full dividend and interest income and the IRS notifies
the payor of such underreporting.
 
     Any amounts withheld under the backup withholding rules will be allowed as
a credit against such U.S. Holder's United States Federal income tax liability
and may entitle such U.S. Holder to a refund, provided the required information
is furnished to the IRS.
 
                              PLAN OF DISTRIBUTION
 
     The Exchange Senior Notes will be offered by Nextel to the holders of the
Private Notes in exchange for the Private Notes pursuant to the Exchange Offer.
 
     Except as described below, a broker-dealer may not participate in the
Exchange Offer in connection with a distribution of the Exchange Senior Notes.
Each broker-dealer that receives Exchange Senior Notes for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Senior Notes. This
Prospectus, as it may be amended or supplemented from time to time, may be used
by a broker-dealer in connection with resales of Exchange Senior Notes received
for its own account in exchange for Private Notes where such Private Notes were
acquired as a result of market-making activities or other trading activities.
The Company has agreed that for a period of 90 days after the Expiration Date,
it will make this Prospectus, as amended or supplemented, available to any
broker-dealer for use in connection with any such resale subject to the
conditions described under "The Exchange Offer -- Resale of the Exchange Senior
Notes."
 
                                       75
<PAGE>   83
 
     The Company will not receive any proceeds from any sale of Exchange Senior
Notes by broker-dealers. Exchange Senior Notes received by broker-dealers for
their own account pursuant to the Exchange Offer may be sold from time to time
in one or more transactions in the over-the-counter market, in negotiated
transactions, through the writing of options on the Exchange Senior Notes or a
combination of such methods of resale, at market prices prevailing at the time
of resale, at prices related to such prevailing market prices, or negotiated
prices. Any such resale may be made directly to purchasers or through brokers or
dealers who may receive compensation in the form of commissions or concessions
from any such broker-dealer and/or the purchasers of any such Exchange Senior
Notes. Any broker or dealer that participates in a distribution of such Exchange
Senior Notes may be deemed to be an "underwriter" within the meaning of the
Securities Act, and any profit on any such resale of Exchange Senior Notes and
any commissions or concessions received by any such persons may be deemed to be
underwriting compensation under the Securities Act. The Letter of Transmittal
states that by acknowledging that it will deliver and by delivering a prospectus
a broker-dealer will not be deemed to admit that it is an "underwriter" within
the meaning of the Securities Act.
 
     The Company has agreed to pay all expenses incident to the Exchange Offer
other than commissions or concessions of any brokers or dealers and expenses of
counsel for the holders of the Exchange Senior Notes and will indemnify the
holders of the Exchange Senior Notes (including any broker-dealers) against
certain liabilities, including liabilities under the Securities Act.
 
                                 LEGAL MATTERS
 
     The legality of the Exchange Senior Notes offered hereby will be passed
upon for Nextel by Jones, Day, Reavis & Pogue, Dallas, Texas.

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. 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 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
 
                                      II-1
<PAGE>   85
 
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 21. 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 22. UNDERTAKINGS.
 
     (a) 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
 
                                      II-6
<PAGE>   90
 
                (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 posteffective 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.
 
     (b) The undersigned registrant hereby undertakes 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 Section 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.
 
     (c) 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 Act and will be governed by the final adjudication of
such issue.
 
     (d) The undersigned registrant hereby undertakes to file an application for
the purpose of determining the eligibility of the trustee to act under
subsection (a) of Section 310 of the Trust Indenture Act in accordance with the
rules and regulations prescribed by the Commission under Section 305(b)(2) of
the Act.
 
     (e) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11, or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.
 
     (f) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

SECTION 101.  Definitions.

                 For all purposes of this Indenture, except as otherwise

                 (3)      whenever this Indenture requires that a particular
         ratio or amount be calculated with respect to a specified period after

<PAGE>   4
         period, unless otherwise specified herein, and all accounting terms
         not otherwise defined herein have the meanings assigned to them in
         accordance with generally accepted accounting principles (whether or
         not such is indicated herein), and, except as otherwise herein
         expressly provided, the term "generally accepted accounting
         principles" with respect to any computation required or permitted
         hereunder shall mean such accounting principles as are generally
         accepted at the date of such computation;

         set forth in (ii) above), minus all amounts theretofore paid in

         management and policies of such Person, directly or indirectly,
         whether through the ownership of voting securities, by contract or

the Trust Indenture Act.  Each such certificate or opinion shall be given in

SECTION 103.  Form of Documents Delivered to Trustee.

                 In any case where several matters are required to be certified
by, or covered by an opinion of, any specified Person, it is not necessary that
all such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

                 Any certificate or opinion of an officer of the Company may be
based, insofar as it relates to legal matters, upon a certificate or opinion
of, or representations by, counsel, unless such officer knows, or in the
exercise of reasonable care should know, that the certificate or opinion or
representations with respect to the matters upon which his certificate or
opinion is based are erroneous.  Any such certificate or opinion of counsel may
be based, insofar as it relates to factual matters, upon a certificate or
opinion of, or representations by, an officer or officers of the Company
stating that the information with respect to such factual matters is in the
possession of the Company, unless such counsel knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to such matters are erroneous.

more applications, requests, consents, certificates, statements, opinions or
other instruments under this Indenture, they may, but need not, be consolidated
and form one instrument.


SECTION 104.  Acts of Holders; Record Dates.

                 Any request, demand, authorization, direction, notice,
consent, waiver or other action provided or permitted by this Indenture to be
given or taken by Holders may be embodied in and evidenced by one or more
instruments of substantially similar tenor signed by such Holders in person or
by agent duly appointed in writing; and, except as herein otherwise expressly
provided, such action shall become effective when such instrument or
instruments are delivered to the Trustee and, where it is hereby expressly
required, to the Company.  Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the
"Act" of the Holders signing such instrument or instruments.  Proof of
execution of any such instrument or of a writing appointing any such agent
shall be sufficient for any purpose of this Indenture and (subject to Section
601) conclusive in favor of the Trustee and the Company, if made in the manner
provided in this Section.





                                       33
<PAGE>   36
                 The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof.  Where
such execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority.  The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner which the Trustee deems sufficient.

                 The ownership of Securities shall be proved by the Security
Register.

                 Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Security shall bind every
future Holder of the same Security and the Holder of every Security issued upon
the registration of transfer thereof or in exchange therefor or in lieu thereof
in respect of anything done, omitted or suffered to be done by the Trustee or
the Company in reliance thereon, whether or not notation of such action is made
upon such Security.

                 The Company may set any day as a record date for the purpose
of determining the Holders of Outstanding Securities entitled to give or take
any request, demand, authorization, direction, notice, consent, waiver or other
action provided or permitted by this Indenture to be given or taken by Holders
of Securities, provided that the Company may not set a record date for, and the
provisions of this paragraph shall not apply with respect to, the giving or
making of any notice, declaration, request or direction referred to in the next
paragraph.  If any record date is set pursuant to this paragraph, the Holders
of Outstanding Securities on such record date, and no other Holders, shall be
entitled to take the relevant action, whether or not such Holders remain
Holders after such record date; provided that no such action shall be effective
hereunder unless taken on or prior to the applicable Record Expiration Date by
Holders of the requisite principal amount of Outstanding Securities on such
record date; and provided, further, that for the purpose of determining whether
Holders of the requisite principal amount of such Securities have taken such
action, no Security shall be deemed to have been Outstanding on such record
date unless it is also Outstanding on the date such action is to become
effective. Nothing in this paragraph shall prevent the Company from setting a
new record date for any action for which a record date has previously been set
pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be canceled and of no effect),
nor shall anything in this paragraph be construed to render ineffective any
action





                                       34
<PAGE>   37
taken by Holders of the requisite principal amount of Outstanding Securities on
the date such action is taken.  Promptly after any record date is set pursuant
to this paragraph, the Company, at its own expense, shall cause notice of such
record date, the proposed action by Holders and the applicable Record
Expiration Date to be given to the Trustee in writing and to each Holder of
Securities in the manner set forth in Section 106.

                 The Trustee may set any day as a record date for the purpose
of determining the Holders of Outstanding Securities entitled to join in the
giving or making of (i) any Notice of Default, (ii) any declaration of
acceleration referred to in Section 502, (iii) any request to institute
proceedings referred to in Section 507(2), (iv) any direction referred to in
Section 512 or (v) the Required Consent.  If any record date is set pursuant to
this paragraph, the Holders of Outstanding Securities on such record date, and
no other Holders, shall be entitled to join in such notice, declaration,
request or direction, whether or not such Holders remain Holders after such
record date; provided that no such action shall be effective hereunder unless
taken on or prior to the applicable Record Expiration Date by Holders of the
requisite principal amount of Outstanding Securities on such record date; and
provided, further, that for the purpose of determining whether Holders of the
requisite principal amount of such Securities have taken such action, no
Security shall be deemed to have been Outstanding on such record date unless it
is also Outstanding on the date such action is to become effective.  Nothing in
this paragraph shall be construed to prevent the Trustee from setting a new
record date for any action (whereupon the record date previously set shall
automatically and without any action by any Person be canceled and of no
effect), nor shall anything in this paragraph be construed to render
ineffective any action taken by Holders of the requisite principal amount of
Outstanding Securities on the date such action is taken.  Promptly after any
record date is set pursuant to this paragraph, the Trustee, at the Company's
expense, shall cause notice of such record date, the matter(s) to be submitted
for potential action by Holders and the applicable Record Expiration Date to be
given to the Company in writing and to each Holder of Securities in the manner
set forth in Section 106.

                 With respect to any record date set pursuant to this Section,
the party hereto that sets such record date may designate any day as the
"Record Expiration Date" and from time to time may change the Record Expiration
Date to any earlier or later day, provided that no such change shall be
effective unless notice of the proposed new Record Expiration Date is given to
the other party hereto in writing, and to each Holder of Securities in the
manner set forth in Section 106, on or before the existing Record Expiration
Date.  If a Record Expiration Date is not designated with respect to any record
date set pursuant to this





                                       35
<PAGE>   38
Section, the party hereto that set such record date shall be deemed to have
initially designated the 180th day after such record date as the Record
Expiration Date with respect thereto, subject to its right to change the Record
Expiration Date as provided in this paragraph.  Notwithstanding the foregoing,
no Record Expiration Date shall be later than the 180th day after the
applicable record date.

                 Without limiting the foregoing, a Holder entitled hereunder to
take any action hereunder with regard to any particular Security may do so with
regard to all or any part of the principal amount of such Security or by one or
more duly appointed agents each of which may do so pursuant to such appointment
with regard to all or any part of such principal amount.


SECTION 105.  Notices, Etc., to Trustee and Company.

                 Any request, demand, authorization, direction, notice,
consent, waiver or Act of Holders or other document provided or permitted by
this Indenture to be made upon, given or furnished to, or filed with,

                 (1)      the Trustee by any Holder or by the Company shall be
         sufficient for every purpose hereunder if made, given, furnished or
         filed in writing and mailed, first-class postage prepaid, to or with
         the Trustee at its Corporate Trust Office, Attention: Indenture Trust
         Division, or

                 (2)      the Company by the Trustee or by any Holder shall be
         sufficient for every purpose hereunder (unless otherwise herein
         expressly provided) if in writing and mailed, first- class postage
         prepaid, to the Company addressed to it at the address of its
         principal office specified in the first paragraph of this instrument
         or at any other address previously furnished in writing to the Trustee
         by the Company.


SECTION 106.  Notice to Holders; Waiver.

                 Where this Indenture provides for notice to Holders of any
event, such notice shall be sufficiently  given (unless otherwise herein
expressly provided) if in writing and mailed, first-class postage prepaid, to
each Holder affected by such event, at his address as it appears in the
Security Register, not later than the latest date (if any), and not earlier
than the earliest date (if any), prescribed for the giving of such notice. In
any case where notice to Holders is given by mail, neither the failure to mail
such notice, nor any defect in any notice so mailed, to any particular Holder
shall affect the sufficiency of





                                       36
<PAGE>   39
such notice with respect to other Holders.  Where this Indenture provides for
notice in any manner, such notice may be waived in writing by the Person
entitled to receive such notice, either before or after the event, and such
waiver shall be the equivalent of such notice.  Waivers of notice by Holders
shall be filed with the Trustee, but such filing shall not be a condition
precedent to the validity of any action taken in reliance upon such waiver.

                 In case by reason of the suspension of regular mail service or
by reason of any other cause it shall be impracticable to give such notice by
mail, then such notification as shall be made with the approval of the Trustee
shall constitute a sufficient notification for every purpose hereunder.


SECTION 107.  Conflict with Trust Indenture Act.

                 If any provision hereof limits, qualifies or conflicts with a
provision of the Trust Indenture Act that is required under such Act to be part
of and govern this Indenture, the latter provision shall control.  If any
provision of this Indenture modifies or excludes any provision of the Trust
Indenture Act that may be so modified or excluded, the latter provision shall
be deemed to apply to this Indenture as so modified or to be excluded, as the
case may be.


SECTION 108.  Effect of Headings and Table of Contents.

                 The Article and Section headings herein and the Table of
Contents are for convenience only and shall not affect the construction hereof.


SECTION 109.  Successors and Assigns.

                 All covenants and agreements in this Indenture by the Company
shall bind its successors and assigns, whether so expressed or not.


SECTION 110.  Separability Clause.

existing under the laws of the State of Delaware (herein called the "Company",
which term includes any successor Person under the Indenture hereinafter
referred to), for value received, hereby promises to pay to __________________,

principal upon acceleration, redemption or repurchase and, in such case, the

or duly provided for.  Interest on any overdue principal or premium shall be
payable on demand.  Any such interest on overdue principal or premium which is
not paid on demand shall bear interest at the rate of 9.75% per annum (to the
extent that the payment of such interest on interest shall be legally
enforceable), from the date of such demand until the amount so demanded is paid

issue discount during the period ending October 31, 2002 and in addition to the
interest otherwise due on the Securities after such date) will accrue from

will accrue from July 31, 1998 at an annual rate of 0.5% of Accreted Value on
the preceding Semiannual Accrual Date) payable in cash semiannually, in
arrears, on each April 30 and October 31, commencing October 31, 1998, until
the earlier of the date upon which (i) the exchange offer is consummated, (ii)
a Shelf Registration Statement with respect to all Registrable Securities (as
defined in the Registration Rights Agreement) is declared effective, or (iii)
the Securities become fully tradeable without registration under the Securities
Act, provided that upon the request of any Holder of the Securities, the
Company will deliver to such Holder certificates evidencing such Holder's
Securities without the Private Placement Legend.  The Holder of this Security
is entitled to the benefits of such Registration Rights Agreement.

                 Payment of the principal of (and premium, if any) and any
interest on this Security will be made at the office or

have the meaning assigned to it in such instrument), between the Company and
Harris Trust and Savings Bank, as Trustee (herein called the "Trustee", which
term includes any successor trustee under the Indenture), and reference is
hereby made to the Indenture for a statement of the respective rights,
limitations of rights, duties and immunities thereunder of the Company, the
Trustee and the Holders of the Securities and of the terms upon which the
Securities are, and are to be, authenticated and delivered.

                 The Securities may be redeemed at any time on or after October
31, 2002, at the Company's option, in whole or in part, upon not less than 30
nor more than 60 days' prior written notice mailed by first class mail to each
holder's last address as it appears in the Security Register, at the Redemption
Prices (expressed as a percentage of the principal amount at maturity thereof)
set forth below, plus an amount in cash equal to all accrued and unpaid
interest, if any, to the Redemption Date, if redeemed during the 12-month
period beginning October 31 of each of the years set forth below.

                      2003                       102.4375%
</TABLE>

                 On or after October 31, 2004, the Company may redeem the
Securities at a Redemption Price equal to 100% of the principal amount at
maturity thereof, together in the case of any such redemption with accrued
interest, if any, to the Redemption Date, but interest installments whose
Stated Maturity is on or prior to such Redemption Date will be payable to the
Holders of such Securities, or one or more Predecessor Securities, of record at
the close of business on the relevant Record Dates referred to on the face
hereof, all as provided in the Indenture.

                 In addition to any redemption provided for in the immediately
preceding paragraphs, in the event of the sale by the Company after the Closing
Date and prior to October 31, 2000 of its Capital Stock (other than Redeemable
Stock) in a single transaction or series of transactions for an aggregate
purchase price equal to or exceeding $125 million, up to a maximum of 33 1/3%
of the aggregate Accreted Value of the Outstanding Securities will, within 180
days of such sale, at the option of the Company, upon not less than 30 nor more
than 60 days' notice by mail, be redeemable from the net proceeds thereof (but
only to the extent such proceeds consist of cash or readily marketable cash
equivalents received in respect of the Company's Capital Stock so sold, in each
case net of all commissions, discounts, fees, expenses and taxes incurred in
respect thereof) at a Redemption Price equal to 109.75% of the Accreted Value
of the Securities to be redeemed to the Redemption Date.

                 For purposes of this Security and the Indenture, Accreted
Value of any Outstanding Security as of or to any date of determination means
an amount equal to the sum of (i) the issue price of such Security as
determined in accordance with Section 1273 of the Code plus (ii) the aggregate
of the portions of the original issue discount (the excess of the amounts
considered as part of the "stated redemption price at maturity" of such
Security within the meaning of Section 1273(a)(2) of the Code or any successor
provisions, whether denominated as principal or interest, over the issue price
of such Security)





                                       43
<PAGE>   46
that shall theretofore have accrued pursuant to Section 1272 of the Code
(without regard to Section 1272(a)(7) of the Code) from the date of issue of
such Security (a) for each six-month or shorter period ending April 30 or
October 31 prior to the date of determination and (b) for the shorter period,
if any, from the end of the immediately preceding six-month or shorter period,
as the case may be, to the date of determination, plus (iii) accrued and unpaid
interest to the date such Accreted Value is paid (without duplication of any
amount set forth in (ii) above), minus all amounts theretofore paid in respect
of such Security, which amounts are considered as part of the "stated
redemption price at maturity" of such Security within the meaning of Section
1273(a)(2) of the Code or any successor provisions (whether such amounts paid
were denominated principal or interest).

                 The Securities do not have the benefit of any sinking fund
obligations.

                 In the event of redemption, or purchase pursuant to an Offer
to Purchase, of this Security in part only, a new Security or Securities for
the unredeemed or unpurchased portion hereof will be issued in the name of the
Holder hereof upon the cancellation hereof.

                 The Indenture contains provisions for defeasance at any time
of the entire indebtedness of this Security or certain restrictive covenants
and Events of Default with respect to this Security, in each case upon
compliance with certain conditions set forth in the Indenture.

                 If an Event of Default shall occur and be continuing, there
may be declared due and payable the Default Amount of the Securities, in the
manner and with the effect provided in the Indenture.  Prior to October 31,
2002, the Default Amount in respect of this Security as of any particular date
shall equal the Accreted Value of this Security as of such date.  On and after
October 31, 2002, the Default Amount in respect of this Security as of any
particular date shall equal 100% of the principal amount payable in respect of
this Security at the Stated Maturity hereof.  Upon payment of (i) the Default
Amount so declared due and payable and any overdue installment of interest in
respect of this Security, (ii) any overdue principal or premium payable on
redemption or repurchase of this Security and (iii) as provided on the face
hereof, any interest on any overdue Default Amount, principal, premium or
interest in respect of this Security (to the extent that the payment of such
interest shall be legally enforceable), all of the Company's obligations in
respect of the payment of the principal of and any premium and interest on this
Security shall terminate.

<PAGE>   47
                 The Indenture provides that, subject to certain conditions, if
a Change of Control occurs, the Company shall be required to make an Offer to
Purchase for all of the Securities.

                 Unless the context otherwise requires, references herein to
the principal amount of any Security mean, as of any day, (i) with respect to
any portion thereof required hereunder to be redeemed or repurchased on any
redemption or repurchase date on or prior to such day, the amount due and
payable in respect of such portion upon such redemption or repurchase date
(excluding premium and interest), (ii) with respect to any portion thereof not
required to be so redeemed or repurchased, but which has been declared due and
payable prior to the Stated Maturity thereof as provided in the Indenture, the
Default Amount in respect of such portion asof such day and (iii) with respect
to any portion thereof not required so to be redeemed or repurchased and not so
declared due and payable, such portion of the principal amount of such Security
payable at Stated Maturity thereof.

                 The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Company and the rights of the Holders of the Securities
under the Indenture at any time by the Company and the Trustee after having
received the Required Consent (defined as follows).  The Indenture also
contains provisions permitting those Persons giving the Required Consent, on
behalf of the Holders of all the Securities, to waive compliance by the Company
with certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences.  Any such consent or waiver by the Holder of
this Security shall be conclusive and binding upon such Holder and upon all
future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Security.

                 As used herein, "Required Consent" means, except as otherwise
expressly provided in the Indenture with respect to matters requiring the
consent of each holder of Securities affected thereby: (i) the consent of
holders of not less than a majority in aggregate principal amount at Stated
Maturity of the Securities for any action to (x) direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee, or
exercising any power conferred upon such Trustee, or (y) consent to or waive,
on behalf of the holders of all the Securities, any past default and its
consequences, and (ii) with respect to all other actions requiring the consent
of holders of the Securities, the consent of either (x) a majority in aggregate
principal amount at Stated Maturity of the Securities or (y) a majority in
aggregate principal amount at Stated Maturity of (I) the Securities, (II) the
September Notes, if the holders of





                                       45
<PAGE>   48
the September Notes are being requested to consent to such action with respect
to the terms of the September Notes or the September Indenture, and (III) any
other issue of unsubordinated, unsecured notes issued by the Company, if such
notes or the indenture pursuant to which such notes were issued both (A)
require the consent of the holders of such notes to such action and (B) provide
that the holders thereof will vote with the holders of the Securities with
respect to such action.

                 As provided in and subject to the provisions of the Indenture,
the Holder of this Security shall not have the right to institute any
proceeding with respect to the Indenture or for the appointment of a receiver
or trustee or for any other remedy thereunder, unless such Holder shall have
previously given the Trustee written notice of a continuing Event of Default
with respect to the Securities, the Holders of not less than 25% in principal
amount at Stated Maturity of the Securities at the time Outstanding shall have
made written request to the Trustee to institute proceedings in respect of such
Event of Default as Trustee and offered the Trustee reasonable indemnity and
the Trustee shall not have received from the Holders of a majority in principal
amount at Stated Maturity of Securities at the time Outstanding a direction
inconsistent with such request, and shall have failed to institute any such
proceeding, within 60 days after receipt of such notice, request and offer of
indemnity. The foregoing shall not apply to certain suits described in the
Indenture, including any suit instituted by the Holder of this Security for the
enforcement of any payment of principal hereof or any premium or interest
hereon on or after the respective due dates expressed herein (or, in the case
of redemption, on or after the Redemption Date or, in the case of any purchase
of this Security required to be made pursuant to an Offer to Purchase, on or
after the Purchase Date.)

                 No reference herein to the Indenture and no provision of this
Security or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of (and
premium, if any) and interest on this Security at the times, place and rate,
and in the coin or currency, herein prescribed.

the Securities are exchangeable for a like aggregate principal amount of
Securities of like tenor of a different authorized denomination, as requested
by the Holder surrendering the same.

                 No service charge shall be made for any such registration of
transfer or exchange, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge payable in connection therewith.

transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Security is registered as the owner

                                 ARTICLE THREE

                                 The Securities

SECTION 301.  Title and Terms.

                 The aggregate principal amount at Stated Maturity of
Securities which may be authenticated and delivered under this Indenture is
limited to $1,129,100,000, except for Securities authenticated and delivered
upon registration of transfer of, or in exchange for, or in lieu of, other
Securities pursuant to Section 304, 305, 308, 906 or 1108 or in connection with
an Offer to Purchase pursuant to Section 1013.

                 The Securities shall be known and designated as the "Senior
Serial Redeemable Discount Notes due 2007" of the Company.  Their Stated
Maturity shall be October 31, 2007 and they shall bear cash interest at the
rate of 9.75% per annum, from October 31, 2002 or from the most recent Interest
Payment Date to which interest has been paid or duly provided for, as the case
may be, payable semi-annually on April 30 and October 31,





                                       52
<PAGE>   55
commencing April 30, 2003 until the principal thereof is paid or made available
for payment.

                 The principal of (and premium, if any) and interest on the
Securities shall be payable at the office or agency of the Company in the
Borough of Manhattan, The City of New York maintained for such purpose and at
any other office or agency maintained by the Company for such purpose;
provided, however, that at the option of the Company payment of interest, may
be made by check mailed to the address of the Person entitled thereto as such
address shall appear in the Security Register.

                 The Company may be required to make an Offer to Purchase the
Securities as provided in Section 1013.

                 The Securities shall be redeemable as provided in Article Two
and Article Eleven.

                 The Securities shall be subject to Defeasance and/or Covenant
Defeasance as provided in Article Twelve.


SECTION 302.  Denominations.

                 The Securities shall be issuable only in registered form
without coupons and only in denominations of  $1,000 principal amount and any
integral multiple thereof.


SECTION 303.  Execution, Authentication, Delivery and Dating.

                 The Securities shall be executed on behalf of the Company by
its Chairman of the Board, its President or one of its Vice Presidents, under
its corporate seal reproduced thereon attested by its Secretary or one of its
Assistant Secretaries. The signature of any of these officers on the Securities
may be manual or facsimile.

                 Securities bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company shall bind
the Company, notwithstanding that such individuals or any of them have ceased
to hold such offices prior to the authentication and delivery of such
Securities or did not hold such offices at the date of such Securities.

                 At any time and from time to time after the execution and
delivery of this Indenture, the Company may deliver Securities executed by the
Company to the Trustee for authentication, together with a Company Order for
the authentication and delivery of such Securities; and the Trustee in
accordance with such Company Order shall authenticate and





                                       53
<PAGE>   56
deliver such Securities as in this Indenture provided and not otherwise.

                 Each Security shall be dated the date of its authentication.

                 No Security shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on
such Security a certificate of authentication substantially in the form
provided for herein executed by the Trustee by manual signature, and such
certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered
hereunder.


SECTION 304.  Temporary Securities.

                 Pending the preparation of definitive Securities, the Company
may execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities which are printed, lithographed, typewritten, mimeographed
or otherwise produced, in any authorized denomination, substantially of the
tenor of the definitive Securities in lieu of which they are issued and with
such appropriate insertions, omissions, substitutions and other variations as
the officers executing such Securities may determine, as evidenced by their
execution of such Securities.

                 If temporary Securities are issued, the Company will cause
definitive Securities to be prepared without unreasonable delay.  After the
preparation of definitive Securities, the temporary Securities shall be
exchangeable for definitive Securities upon surrender of the temporary
Securities at any office or agency of the Company designated pursuant to
Section 1002, without charge to the Holder.  Upon surrender for cancellation of
any one or more temporary Securities the Company shall execute and the Trustee
shall authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of authorized denominations and of a like tenor. Until so
exchanged the temporary Securities shall in all respects be entitled to the
same benefits under this Indenture as definitive Securities.


SECTION 305.    Registration, Registration of Transfer and Exchange.

                 The Company shall cause to be kept at the Corporate Trust
Office of the Trustee a register (the register maintained in such office and in
any other office or agency designated pursuant to Section 1002 being herein
sometimes collectively referred to as the "Security Register") in which,
subject to such





                                       54
<PAGE>   57
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and of transfers of Securities.  The Trustee is
hereby appointed "Security Registrar" for the purpose of registering Securities
and transfers of Securities as herein provided.

                 Upon surrender for registration of transfer of any Security at
an office or agency of the Company designated pursuant to Section 1002 for such
purpose, the Company shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Securities of any authorized denominations and of a like aggregate
principal amount and tenor.  No such transfer shall be effected until, and such
transferee shall succeed to the rights of a Holder only upon, final acceptance
and registration of the transfer by the Security Registrar in the Security
Register. Prior to the registration of any transfer by a Holder as provided
herein, the Company, the Trustee and any agent of the Company shall treat the
person in whose name the Security is registered as the owner thereof for all
purposes whether or not the Security shall be overdue, and neither the Company,
the Trustee, nor any such agent shall be affected by notice to the contrary.
Furthermore, any Holder of a Global Security shall, by acceptance of such
Global Security, agree that transfers of beneficial interests in such Global
Security may be effected only through a book entry system maintained by the
Holder of such Global Security (or its agent) and that ownership of a
beneficial interest in the Security shall be required to be reflected in a book
entry.

                 At the option of the Holder, Securities may be exchanged for
other Securities (including an exchange of securities for Exchange Securities)
of any authorized denominations and of a like aggregate principal amount and
tenor, upon surrender of the Securities to be exchanged at such office or
agency provided, that no exchange of Securities for Exchange Securities shall
occur until a Registration Statement shall have been declared effective by the
Commission and that Securities that are exchanged for Exchange Securities
pursuant to such Registration Statement shall be canceled by the Trustee.
Whenever any Securities are so surrendered for exchange, the Company shall
execute, and the Trustee shall authenticate and deliver, the Securities which
the Holder making the exchange is entitled to receive.

                 All Securities issued upon any registration of transfer or
exchange of Securities shall be the valid obligations of the Company,
evidencing the same debt, and entitled to the same benefits under this
Indenture, as the Securities surrendered upon such registration of transfer or
exchange.





                                       55
<PAGE>   58
                 Every Security presented or surrendered for registration of
transfer or for exchange shall (if so required by the Company or the Trustee)
be duly endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed, by the
Holder thereof or his attorney duly authorized in writing.

                 No service charge shall be made for any registration of
transfer or exchange of Securities, but the Company may require payment of a
sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any registration of transfer or exchange of
Securities, other than exchanges pursuant to Section 304, 906 or 1108 or in
accordance with any Offer to Purchase pursuant to Section 1013, and in any such
case not involving any transfer.

                 The Company shall not be required (i) to issue, register the
transfer of or exchange any Security during a period beginning at the opening
of business 15 days before the day of the mailing of a notice of redemption of
Securities selected for redemption under Section 1104 and ending at the close
of business on the day of such mailing, or (ii) to register the transfer of or
exchange any Security so selected for redemption in whole or in part, except
the unredeemed portion of any Security being redeemed in part.

SECTION 306.    Book-Entry Provisions for Global Security.

                 (a) The Global Security initially shall (i) be registered in
the name of the Depository for such Global Security or the nominee of such
Depository; (ii) be delivered to the Trustee as custodian for such Depository;
and (iii) bear legends as set forth in Section 205.

                 Members of, or participants in, the Depository ("Agent
Members") shall have no rights under this Indenture with respect to any Global
Security held on their behalf by the Depository, or the Trustee as its
custodian, or under the Global Security and the Depository may be treated by
the Company, the Trustee and any agent of the Company or the Trustee as the
absolute owner of such Global Security for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the Company, the
Trustee or any agent of the Company or the Trustee, from giving effect to any
written certification, proxy or other authorization furnished by the Depository
or impair, as between the Depository and its Agent Members, the operation of
customary practices governing the exercise of the rights of a holder of any
Security.

                 (b) Transfers of a Global Security shall be limited to
transfers of such Global Security in whole, but not in part, to the Depository,
its successors or their respective nominees. Interests of beneficial owners in
a Global Security may be





                                       56
<PAGE>   59
transferred in accordance with the rules and procedures of the Depository and
the provisions of Section 307.  In addition, U.S.  Physical Securities and
Offshore Physical Securities shall be transferred to all beneficial owners in
exchange for their beneficial interests in the U.S. Global Securities or
Offshore Global Securities, respectively, if (i) the Depository notifies the
Company that it is unwilling or unable to continue as Depository for the U.S.
Global Securities or Offshore Global Securities, as the case may be, and a
successor depository is not appointed by the Company within 90 days of such
notice, (ii) an Event of Default has occurred and is continuing and the
Security Registrar has received a request therefor from the Depository or (iii)
in accordance with the rules and procedures of the Depository and the
provisions of Section 307.

                 (c) In connection with any transfer of a portion of the
beneficial interests in the Global Security to beneficial owners pursuant to
paragraph (b) of this Section, the Security Registrar shall reflect on the
Security Register the date and a decrease in the principal amount of the Global
Security in an amount equal to the principal amount of the beneficial interest
in the Global Security to be transferred, and the Company shall execute, and
the Trustee shall authenticate and deliver, one or more Physical Securities of
like tenor and amount.

                 (d) In connection with the transfer of an entire U.S. Global
Security or Offshore Global Security to beneficial owners pursuant to paragraph
(b) of this Section, such U.S. Global Security or Offshore Global Security
shall be deemed to be surrendered to the Trustee for cancellation, and the
Company shall execute, and the Trustee shall authenticate and deliver, to each
beneficial owner identified by the Depository in exchange for its beneficial
interest in such U.S. Global Security or Offshore Global Security, as the case
may be, an equal aggregate principal amount of U.S. Physical Securities or
Offshore Physical Securities of authorized denominations.

                 (e) Any Physical Security delivered in exchange for an
interest in the Global Security pursuant to paragraph (b), (c) or (d) of this
Section shall, except as otherwise provided by paragraph (d) of Section 307
bear the legend regarding transfer restrictions applicable to the Physical
Securities set forth in Section 205.

                 (f) The registered holder of a Global Security may grant
proxies and otherwise authorize any person, including Agent Members and persons
that may hold interests through Agent Members, to take any action which a
Holder is entitled to take under this Indenture or the Securities.

<PAGE>   60
                 Unless and until a Security is exchanged for an Exchange

pursuant to the Registration Rights Agreement, the following provisions shall
apply:

                 (a)      Transfers to QIBs.  The following provisions shall

         U.S. Physical Securities or (B) an interest in an Offshore Global
         Security  prior to the removal of the Private Placement Legend, the
         Security Registrar shall register the transfer if such transfer is
         being made by a proposed transferor who has checked the box provided
         for on the form of security stating, or has otherwise advised the
         Company and the Security Registrar in writing, that the sale has been
         made in compliance with the provisions of Rule 144A, to a transferee
         who has signed the certification provided for on the form of Security
         stating, or has otherwise advised the Company and the Security
         Registrar in writing, that it is purchasing the Security for its own
         account or an account with respect to which it exercises sole
         investment discretion and that it and any such account is a QIB within
         the meaning of Rule 144A, and is aware that the sale to it is being
         made in reliance on Rule 144A and acknowledges that it has received
         such information regarding the Company as it has requested pursuant to
         Rule 144A or has determined not to request such information and that
         it is aware that the transferor is relying upon its foregoing
         representations in order to claim the exemption from registration
         provided by Rule 144A or (y) an interest in a U.S. Global Security,
         the transfer of such interest may be effected only through the book
         entry system maintained by the Depository.

                 (ii)     If the proposed transferee is an Agent Member, and
         the Security to be transferred consists of U.S. Physical Securities,
         upon receipt by the Security Registrar of the documents referred to in
         clause (i) and instructions given in accordance with the Depository's
         and the Security Registrar's procedures, the Security Registrar shall

         principal amount at maturity of the U.S. Global Security in an amount
         equal to the principal amount at maturity of the U.S. Physical
         Securities to be transferred, and the Trustee shall cancel the U.S.
         Physical Securities so transferred.

                 (b)      Transfers to Non-QIB Institutional Accredited
Investors. The following provisions shall apply with respect to

Accredited Investor which is not a QIB (excluding Non-U.S. Persons):

                 (i)      The Security Registrar shall register the transfer of
         any Security, whether or not such Security bears the Private Placement
         Legend, if (x) the requested transfer is after the time period
         referred to in Rule 144(k) under the Securities Act as in effect with
         respect to such transfer or (y) the proposed transferee has delivered
         to the Security Registrar (A) a certificate substantially in the form
         of Exhibit B hereto and (B) if the aggregate principal amount of the
         Notes being transferred is less than $250,000 at the time of such
         transfer, an Opinion of Counsel acceptable to the Company that such
         transfer is in compliance with the Securities Act.

                 (ii)     If the proposed transferor is an Agent Member holding
         a beneficial interest in the U.S. Global Security, upon receipt by the
         Security Registrar of (x) the documents, if any, required by the
         preceding paragraph (i), and (y) instructions given in accordance with
         the Depositary's and the Security Registrar's procedures, the Security
         Registrar shall reflect on its books and records the date and a
         decrease in the principal amount of the U.S. Global Security in an
         amount equal to the principal amount of the beneficial interest in the
         U.S. Global Security to be transferred, and the Company shall execute,
         and the Trustee shall authenticate and deliver, one or more U.S.
         Physical Securities of like tenor and amount.

                 (c)      Transfers of Interests in the Offshore Global
Securities or Offshore Physical Securities.  The following provisions shall
apply with respect to any transfer of interests in the Offshore Global
Securities or Offshore Physical Securities:

                 (i)      prior to removal of the Private Placement Legend from
         an Offshore Global Security or Offshore Physical Security pursuant to
         Section 205, the Security Registrar shall refuse to register such
         transfer unless such transfer complies with Section 307(a) or Section
         307(d), as the case may be; and

                 (ii)     after such removal, the Security Registrar shall
         register the transfer of any such Security without requiring any
         additional certification.

                 (d)      Transfers to Non-U.S. Persons at Any Time.  The
following provisions shall apply with respect to any transfer of a Security to
a Non-U.S. Person:





                                       59
<PAGE>   62
                 (i)      The Security Registrar shall register any proposed
         transfer to any Non-U.S. Person if the Security to be transferred is a
         U.S. Physical Security or an interest in a U.S. Global Security only
         upon receipt of a certificate substantially in the form of Exhibit C
         hereto from the proposed transferor.

                 (ii)     (A)     If the proposed Transferor is an Agent Member
         holding a beneficial interest in a U.S. Global Security, upon receipt
         by the Security Registrar of (x) the documents required by paragraph
         (i) and (y) instructions in accordance with the Depositary's and the
         Security Registrar's procedures, the Security Registrar shall reflect
         on its books and records the date and a decrease in the principal
         amount of such U.S. Global Security in an amount equal to the
         principal amount of the beneficial interest in the U.S. Global
         Security to be transferred, and (B) if the proposed transferee is an
         Agent Member, upon receipt by the Security Registrar of instructions
         given in accordance with the Depositary's and the Security Registrar's
         procedures, the Security Registrar shall reflect on its books and
         records the date and an increase in the principal amount of the
         Offshore Global Security in an amount equal to the principal amount of
         the U.S. Physical Securities or the U.S. Global Security, as the case
         may be, to be transferred, and the Trustee shall cancel the Physical
         Security, if any, so transferred or decrease the amount of the U.S.
         Global Security.

                 (e)      Private Placement Legend.  Upon the transfer,
exchange or replacement of Securities not bearing the Private Placement Legend,
the Security Registrar shall deliver Securities that do not bear the Private
Placement Legend.  Upon the transfer, exchange or replacement of securities
bearing the Private Placement Legend, the Security Registrar shall deliver only
Securities that bear the Private Placement Legend unless either (i) the
circumstances contemplated by Section 205 exist or (ii) there is delivered to
the Trustee an Opinion of Counsel reasonably satisfactory to the Company and
the Trustee to the effect that neither such legend nor the related restrictions
on transfer are required in order to maintain compliance with the provisions of
the Securities Act.

                 (f)      General.  By its acceptance of any Security bearing
the Private Placement Legend, each Holder of such a Security acknowledges the
restrictions on transfer of such Security set forth in this Indenture and in
the Private Placement Legend and agrees that it will transfer such Security
only as provided in this Indenture.  The Security Registrar shall not register
a transfer of any Security unless such transfer complies with the restrictions
on transfer of such Security set forth in the Private Placement Legend and in
this Indenture.  In





                                       60
<PAGE>   63
connection with any transfer of Securities, each Holder agrees by its
acceptance of the Securities to furnish the Trustee or the Company such
certifications, legal opinions or other information as either of them may
reasonably require to confirm that such transfer is being made pursuant to an
exemption from, or a transaction not subject to, the registration requirements
of the Securities Act; provided that the Trustee shall not be required to
determine (but may rely on a determination made by the Company with respect to)
the sufficiency of any such certifications, legal opinions or other
information.

                 The Trustee shall retain copies of all letters, notices and
other written communications received pursuant to Section 306 or this Section
307.  The Company shall have the right to inspect and make copies of all such
letters, notices or other written communications at any reasonable time upon
the giving of reasonable written notice to the Trustee.

SECTION 308.  Mutilated, Destroyed, Lost and Stolen Securities.

                 If any mutilated Security is surrendered to the Trustee, the
Company shall execute and the Trustee shall authenticate and deliver in
exchange therefor a new Security of like tenor and principal amount and bearing
a number not contemporaneously outstanding.

                 If there shall be delivered to the Company and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any
Security and (ii) such security or indemnity as may be required by them to save
each of them and any agent of either of them harmless, then, in the absence of
notice to the Company or the Trustee that such Security has been acquired by a
bona fide purchaser, the Company shall execute and upon its request the Trustee
shall authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security, a new Security of like tenor and principal amount and bearing a
number not contemporaneously outstanding.

                 In case any such mutilated, destroyed, lost or stolen Security
has become or is about to become due and payable, the Company in its discretion
may, instead of issuing a new Security, pay such Security.

                 Upon the issuance of any new Security under this Section, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

                 Every new Security issued pursuant to this Section in lieu of
any destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Company,





                                       61
<PAGE>   64
whether or not the destroyed, lost or stolen Security shall be at any time
enforceable by anyone, and shall be entitled to all the benefits of this
Indenture equally and proportionately with any and all other Securities duly
issued hereunder.

                 The provisions of this Section are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Securities.


SECTION 309.  Payment of Interest; Interest Rights Preserved.

                 Interest on any Security which is payable, and is punctually
paid or duly provided for, on any Interest Payment Date shall be paid to the
Person in whose name that Security (or one or more Predecessor Securities) is
registered at the close of business on the Regular Record Date for such
interest.

                 Any interest on any Security which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in Clause (1) or (2) below:

                 (1)      The Company may elect to make payment of any
         Defaulted Interest to the Persons in whose names the Securities (or
         their respective Predecessor Securities) are registered at the close
         of business on a Special Record Date for the payment of such Defaulted
         Interest, which shall be fixed in the following manner.  The Company
         shall notify the Trustee in writing of the amount of Defaulted
         Interest proposed to be paid on each Security and the date of the
         proposed payment, and at the same time the Company shall deposit with
         the Trustee an amount of money equal to the aggregate amount proposed
         to be paid in respect of such Defaulted Interest or shall make
         arrangements satisfactory to the Trustee for such deposit prior to the
         date of the proposed payment, such money when deposited to be held in
         trust for the benefit of the Persons entitled to such Defaulted
         Interest as in this Clause provided.  Thereupon the Trustee shall fix
         a Special Record Date for the payment of such Defaulted Interest which
         shall be not more than 15 days and not less than 10 days prior to the
         date of the proposed payment and not less than 10 days after the
         receipt by the Trustee of the notice of the proposed payment.  The
         Trustee shall promptly notify the Company of such Special Record Date
         and, in the name and at the expense of the Company, shall cause notice
         of the proposed payment of such Defaulted Interest and the Special
         Record Date therefor to





                                       62
<PAGE>   65
         be given to each Holder in the manner specified in Section 106, not
         less than 10 days prior to such Special Record Date.  Notice of the
         proposed payment of such Defaulted Interest and the Special Record
         Date therefor having been so mailed, such Defaulted Interest shall be
         paid to the Persons in whose names the Securities (or their respective
         Predecessor Securities) are registered at the close of business on
         such Special Record Date and shall no longer be payable pursuant to
         the following Clause (2).

                 (2)      The Company may make payment of any Defaulted
         Interest in any other lawful manner not inconsistent with the
         requirements of any securities exchange on which the Securities may be
         listed, and upon such notice as may be required by such exchange, if,
         after notice given by the Company to the Trustee of the proposed
         payment pursuant to this Clause, such manner of payment shall be
         deemed practicable by the Trustee.

                 Subject to the foregoing provisions of this Section, each
Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other
Security.


SECTION 310.  Persons Deemed Owners.

                 Prior to due presentment of a Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Security is registered as the owner of
such Security for the purpose of receiving payment of principal of (and
premium, if any) and (subject to Section 309) interest on such Security and for
all other purposes whatsoever, whether or not such Security be overdue, and
neither the Company, the Trustee nor any agent of the Company or the Trustee
shall be affected by notice to the contrary.


SECTION 311.  Cancellation.

                 All Securities surrendered for payment, redemption,
registration of transfer or exchange or for credit against any Offer to
Purchase pursuant to Section 1013 shall, if surrendered to any Person other
than the Trustee, be delivered to the Trustee and shall be promptly canceled by
it.  The Company may at any time deliver to the Trustee for cancellation any
Securities previously authenticated and delivered hereunder which the Company
may have acquired in any manner whatsoever, and all Securities so delivered
shall be promptly canceled by the Trustee.  No Securities shall be
authenticated in lieu of or in





                                       63
<PAGE>   66
exchange for any Securities canceled as provided in this Section, except as
expressly permitted by this Indenture.  All canceled Securities held by the
Trustee shall be disposed of as directed by a Company Order; provided, however,
that the Trustee shall not be required to destroy canceled Securities.

SECTION 312.  Computation of Interest.

                 Interest on the Securities shall be computed on the basis of a
360-day year of twelve 30-day months.


SECTION 313.  CUSIP, CINS and ISIN Numbers.

                 The Company in issuing the Securities may use "CUSIP," "CINS"
and "ISIN" numbers (if then generally in use), and, if so, the Trustee shall
use the "CUSIP," "CINS" and "ISIN" numbers in notices of redemption or
repurchase as a convenience to Holders; provided that any such notice may state
that no representation is made as to the correctness of such numbers either as
printed on the Securities or as contained in any notice of a redemption or
repurchase and that reliance may be placed only on the other identification
numbers printed on the Securities, and any such redemption or repurchase shall
not be affected by any defect in or omission of such numbers.

                          Company,

                 and the Company, in the case of (i), (ii) or (iii) above, has

                 such deposit (in the case of Securities which have become due
                 and payable) or to the Stated Maturity or Redemption Date, as
                 the case may be;

         Certificate and an Opinion of Counsel, each stating that all

SECTION 502.  Acceleration of Maturity; Rescission and Annulment.

                 If an Event of Default (other than an Event of Default
specified in Section 501(8) or (9)) occurs and is continuing, then and in every
such case the Trustee or the Holders of not less than 25% in principal amount
at Stated Maturity of the Outstanding Securities may declare the Default Amount
of all the Securities to be due and payable immediately, by a notice in writing
to the Company (and to the Trustee if given by Holders), and upon any such
declaration such Default Amount and any accrued interest shall become
immediately due and payable.  If an Event of Default specified in Section
501(8) or (9) occurs, the Default Amount of and any accrued interest on the
Securities then Outstanding shall ipso facto become immediately due and payable
without any declaration or other Act on the part of the Trustee or any Holder.

                 Prior to October 31, 2002, the "Default Amount" in respect of
any particular Security as of any particular date shall equal the Accreted
Value of the Security as of such date. On and after October 31, 2002, the
Default Amount in respect of any particular Security as of any particular date
shall equal 100% of the principal amount payable in respect of the Security at
the Stated Maturity thereof.

                 At any time after such a declaration of acceleration has been
made and before a judgment or decree for payment of the money due has been
obtained by the Trustee as hereinafter in this Article provided, the Holders of
a majority in principal amount at Stated Maturity of the Outstanding
Securities, by written





                                       68
<PAGE>   71
notice to the Company and the Trustee, may rescind and annul such declaration
and its consequences if

                 (1)      the Company has paid or deposited with the Trustee a
         sum sufficient to pay

                          (A)     all overdue interest on all Securities
                 (without duplication of any amount thereof paid or deposited
                 pursuant to Clause (B) or (C) below),

                          (B)     the principal of (and premium, if any, on)
                 any Securities which have become due otherwise than by such
                 declaration of acceleration (including any Securities required
                 to have been purchased on the Purchase Date pursuant to an
                 Offer to Purchase made by the Company) and, to the extent that
                 payment of such interest is lawful, interest thereon at the
                 rate provided by the Securities (without duplication of any
                 amount thereof paid or deposited pursuant to Clause (A) above
                 or Clause (C) below),

                          (C)     to the extent that payment of such interest
                 is lawful, interest upon overdue interest at the rate provided
                 by the Securities (without duplication of any amount thereof
                 paid or deposited pursuant to Clause (A) or (B) above), and

                          (D)     all sums paid or advanced by the Trustee
                 hereunder and the reasonable compensation, expenses,
                 disbursements and advances of the Trustee, its agents and
                 counsel;

         and

                 (2)      all Events of Default, other than the non-payment of
         the principal of Securities which have become due solely by such
         declaration of acceleration, have been cured or waived as provided in
         Section 513.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.

                 Unless the context otherwise requires, references in this
Indenture to the principal amount of any Security mean, as of any day, (i) with
respect to any portion thereof required thereunder to be redeemed or
repurchased on any redemption or repurchase date on or prior to such day, the
amount due and payable in respect of such portion upon such redemption or
repurchase date (excluding premium and interest), (ii) with respect to any
portion thereof not required to be so redeemed or repurchased, but which has
been declared due and payable prior to the Stated Maturity thereof, the Default
Amount in respect of





                                       69
<PAGE>   72
such portion as of such day and (iii) with respect to any portion thereof not
required so to be redeemed or repurchased and not so declared due and payable,
such portion of the principal amount of such Security payable at Stated
Maturity thereof.


SECTION 503.     Collection of Indebtedness and Suits for
                 Enforcement by Trustee.

                 The Company covenants that if

                 (1)      default is made in the payment of any interest on any
         Security when such interest becomes due and payable and such default
         continues for a period of 30 days, or

                 (2)      default is made in the payment of the principal of
         (or premium, if any, on) any Security at the Maturity thereof or, with
         respect to any Security required to have been purchased pursuant to an
         Offer to Purchase made by the Company, at the Purchase Date thereof,

the Company will, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities, the whole amount then due and
payable on such Securities for principal (and premium, if any) and interest,
and, to the extent that payment of such interest shall be legally enforceable,
interest on any overdue principal (and premium, if any) and on any overdue
interest, at the rate provided by the Securities, and, in addition thereto,
such further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

                 If an Event of Default occurs and is continuing, the Trustee
may in its discretion proceed to protect and enforce its rights and the rights
of the Holders by such appropriate judicial proceedings as the Trustee shall
deem most effectual to protect and enforce any such rights, whether for the
specific enforcement of any covenant or agreement in this Indenture or in aid
of the exercise of any power granted herein, or to enforce any other proper
remedy.


SECTION 504.  Trustee May File Proofs of Claim.

                 In case of any judicial proceeding relative to the Company (or
any other obligor upon the Securities), its property or its creditors, the
Trustee shall be entitled and empowered, by intervention in such proceeding or
otherwise, to take any and all actions authorized under the Trust Indenture Act
in order to have claims of the Holders and the Trustee allowed in any such
proceeding.  In particular, the Trustee shall be authorized to





                                       70
<PAGE>   73
collect and receive any moneys or other property payable or deliverable on any
such claims and to distribute the same; and any custodian, receiver, assignee,
trustee, liquidator, sequestrator or other similar official in any such
judicial proceeding is hereby authorized by each Holder to make such payments
to the Trustee and, in the event that the Trustee shall consent to the making
of such payments directly to the Holders, to pay to the Trustee any amount due
it for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 607.

                 No provision of this Indenture shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or the rights of any Holder thereof or to authorize
the Trustee to vote in respect of the claim of any Holder in any such
proceeding; provided, however, that the Trustee may, on behalf of the Holders,
vote for the election of a trustee in bankruptcy or similar official and be a
member of a creditors' or other similar committee.


SECTION 505.     Trustee May Enforce Claims Without Possession of
                 Securities.

                 All rights of action and claims under this Indenture or the
Securities may be prosecuted and enforced by the Trustee without the possession
of any of the Securities or the production thereof in any proceeding relating
thereto, and any such proceeding instituted by the Trustee shall be brought in
its own name as trustee of an express trust, and any recovery of judgment
shall, after provision for the payment of the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, be
for the ratable benefit of the Holders of the Securities in respect of which
such judgment has been recovered.


SECTION 506.  Application of Money Collected.

                 Any money collected by the Trustee pursuant to this Article
shall be applied in the following order, at the date or dates fixed by the
Trustee and, in case of the distribution of such money on account of principal
(or premium, if any) or interest, upon presentation of the Securities and the
notation thereon of the payment if only partially paid and upon surrender
thereof if fully paid:

                 FIRST:  To the payment of all amounts due the Trustee under
         Section 607; and





                                       71
<PAGE>   74
                 SECOND:  To the payment of the amounts then due and unpaid for
         principal of (and premium, if any) and interest on the Securities in
         respect of which or for the benefit of which such money has been
         collected, ratably, without preference or priority of any kind,
         according to the amounts due and payable on such Securities for
         principal (and premium, if any) and interest, respectively.


SECTION 507.  Limitation on Suits.

                 No Holder of any Security shall have any right to institute
any proceeding, judicial or otherwise, with respect to this Indenture, or for
the appointment of a receiver or trustee, or for any other remedy hereunder,
unless

                 (1)      such Holder has previously given written notice to
         the Trustee of a continuing Event of Default;

                 (2)      the Holders of not less than 25% in principal amount
         at Stated Maturity of the Outstanding Securities shall have made
         written request to the Trustee to institute proceedings in respect of
         such Event of Default in its own name as Trustee hereunder;

                 (3)      such Holder or Holders have offered to the Trustee
         reasonable indemnity against the costs, expenses and liabilities to be
         incurred in compliance with such request;

                 (4)      the Trustee for 60 days after its receipt of such
         notice, request and offer of indemnity has failed to institute any
         such proceeding; and

                 (5)      no direction inconsistent with such written request
         has been given to the Trustee during such 60-day period by the Holders
         of a majority in principal amount at Stated Maturity of the
         Outstanding Securities;

it being understood and intended that no one or more Holders shall have any
right in any manner whatever by virtue of, or by availing of, any provision of
this Indenture to affect, disturb or prejudice the rights of any other Holders,
or to obtain or to seek to obtain priority or preference over any other Holders
or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and ratable benefit of all the Holders.





                                       72
<PAGE>   75
SECTION 508.   Unconditional Right of Holders to Receive
               Principal, Premium and Interest.

                 Notwithstanding any other provision in this Indenture, the
Holder of any Security shall have the right, which is absolute and
unconditional, to receive payment of the principal of (and premium, if any) and
(subject to Section 309) interest on such Security on the respective Stated
Maturities expressed in such Security (or, in the case of redemption, on the
Redemption Date or in the case of an Offer to Purchase made by the Company and
required to be accepted as to such Security, on the Purchase Date) and to
institute suit for the enforcement of any such payment, and such rights shall
not be impaired without the consent of such Holder.


SECTION 509.  Restoration of Rights and Remedies.

                 If the Trustee or any Holder has instituted any proceeding to
enforce any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders
shall be restored severally and respectively to their former positions
hereunder and thereafter all rights and remedies of the Trustee and the Holders
shall continue as though no such proceeding had been instituted.


SECTION 510.  Rights and Remedies Cumulative.

                 Except as otherwise provided with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities in the last
paragraph of Section 308, no right or remedy herein conferred upon or reserved
to the Trustee or to the Holders is intended to be exclusive of any other right
or remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise.  The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent
the concurrent assertion or employment of any other appropriate right or
remedy.


SECTION 511.  Delay or Omission Not Waiver.

                 No delay or omission of the Trustee or of any Holder of any
Security to exercise any right or remedy accruing upon any Event of Default
shall impair any such right or remedy or constitute a waiver of any such Event
of Default or an acquiescence therein.  Every right and remedy given by this





                                       73
<PAGE>   76
Article or by law to the Trustee or to the Holders may be exercised from time
to time, and as often as may be deemed expedient, by the Trustee or by the
Holders, as the case may be.


SECTION 512.  Control by Holders.

                 By giving the Required Consent, those Persons giving the
Required Consent shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or exercising
any trust or power conferred on the Trustee, provided that

                 (1)      such direction shall not be in conflict with any rule
         of law or with this Indenture, and

                 (2)      the Trustee may take any other action deemed proper
         by the Trustee which is not inconsistent with such direction.


SECTION 513.  Waiver of Past Defaults.

                 By giving the Required Consent, those Persons giving the
Required Consent may, on behalf of the Holders of all the Securities, waive any
past default hereunder and its consequences, except a default

                 (1)      in the payment of the principal of (or premium, if
         any) or interest on any Security (including any Security which is
         required to have been purchased pursuant to an Offer to Purchase which
         has been made by the Company), or

                 (2)      in respect of a covenant or provision hereof which
         under Article Nine cannot be modified or amended without the consent
         of the Holder of each Outstanding Security affected.

                 Upon any such waiver, such default shall cease to exist, and
any Event of Default arising therefrom shall be deemed to have been cured, for
every purpose of this Indenture; but no such waiver shall extend to any
subsequent or other default or impair any right consequent thereon.


SECTION 514.  Undertaking for Costs.

                 In any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, a court may require any party litigant in
such suit to file an undertaking to pay the costs of such suit, and may assess
costs against any such party litigant, in the manner and to the extent provided
in the





                                       74
<PAGE>   77
Trust Indenture Act; provided, that neither this Section nor the Trust
Indenture Act shall be deemed to authorize any court to require such an
undertaking or to make such an assessment in any suit instituted by the
Company.


SECTION 515.  Waiver of Stay or Extension Laws.

                 The Company covenants (to the extent that it may lawfully do
so) that it will not at any time insist upon, or plead, or in any manner
whatsoever claim or take the benefit or advantage of, any usury, stay or
extension law wherever enacted, now or at any time hereafter in force, which
may affect the covenants or the performance of this Indenture; and the Company
(to the extent that it may lawfully do so) hereby expressly waives all benefit
or advantage of any such law and covenants that it will not hinder, delay or
impede the execution of any power herein granted to the Trustee, but will
suffer and permit the execution of every such power as though no such law had
been enacted.


                                  ARTICLE SIX

                                  The Trustee

SECTION 601.  Certain Duties and Responsibilities.

                 The duties and responsibilities of the Trustee shall be as
provided by the Trust Indenture Act.  Notwithstanding the foregoing, no
provision of this Indenture shall require the Trustee to expend or risk its own
funds or otherwise incur any financial liability in the performance of any of
its duties hereunder, or in the exercise of any of its rights or powers, if it
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to
it.  Whether or not therein expressly so provided, every provision of this
Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee shall be subject to the provisions of this Section.


SECTION 602.  Notice of Defaults.

                 The Trustee shall give the Holders notice of any Default
hereunder as and to the extent provided by the Trust Indenture Act; provided,
however, that in the case of any Default of the character specified in Section
501(5), no such notice to Holders shall be given until at least 30 days after
the occurrence thereof.

         or refraining from acting upon any resolution, certificate, statement,
         instrument, opinion, report, notice, request, direction, consent,
         order, bond, debenture, note, other evidence of indebtedness or other
         paper or document believed by it to be genuine and to have been signed
         or presented by the proper party or parties;

                 (b)      any request or direction of the Company mentioned
         herein shall be sufficiently evidenced by a Company Request or Company
         Order and any resolution of the Board of Directors may be sufficiently
         evidenced by a Board Resolution;

                 (c)      whenever in the administration of this Indenture the
         Trustee shall deem it desirable that a matter be proved or established
         prior to taking, suffering or omitting any action hereunder, the
         Trustee (unless other evidence be herein specifically prescribed) may,
         in the absence of bad faith on its part, rely upon an Officers'
         Certificate;

                 (d)      the Trustee may consult with counsel and the advice
         of such counsel or any Opinion of Counsel shall be full and complete
         authorization and protection in respect of any action taken, suffered
         or omitted by it hereunder in good faith and in reliance thereon;

                 (e)      the Trustee shall be under no obligation to exercise
         any of the rights or powers vested in it by this Indenture at the
         request or direction of any of the Holders pursuant to this Indenture,
         unless such Holders shall have offered to the Trustee reasonable
         security or indemnity against the costs, expenses and liabilities
         which might be incurred by it in compliance with such request or
         direction;

                 (f)      the Trustee shall not be bound to make any
         investigation into the facts or matters stated in any resolution,
         certificate, statement, instrument, opinion, report, notice, request,
         direction, consent, order, bond, debenture, note, other evidence of
         indebtedness or other paper or document, but the Trustee, in its
         discretion, may make such further inquiry or investigation into such
         facts or matters as it may see fit, and, if the Trustee shall
         determine to make such further inquiry or investigation, it shall be
         entitled (subject to reasonable confidentiality arrangements as may be
         proposed by the Company) to examine the books, records and premises of
         the Company, personally or by agent or attorney; and

         hereunder or perform any duties hereunder either directly or by or
         through agents or attorneys and the Trustee shall not be responsible
         for any misconduct or negligence on the part of any agent or attorney
         appointed with due care by it hereunder.


SECTION 604.    Not Responsible for Recitals or Issuance of
                Securities.

                 The recitals contained herein and in the Securities, except
the Trustee's certificates of authentication, shall be taken as the statements
of the Company, and the Trustee assumes no responsibility for their
correctness.  The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Securities.  The Trustee shall not be
accountable for the use or application by the Company of Securities or the
proceeds thereof.


SECTION 605.  May Hold Securities.

                 The Trustee, any Authenticating Agent, any Paying Agent, any
Security Registrar or any other agent of the Company, in its individual or any
other capacity, may become the owner or pledgee of Securities and, subject to
Sections 608 and 613, may otherwise deal with the Company with the same rights
it would have if it were not Trustee, Authenticating Agent, Paying Agent,
Security Registrar or such other agent.


SECTION 606.  Money Held in Trust.

                 Money held by the Trustee in trust hereunder need not be

         compensation as the Company and the Trustee shall from time to time
         agree in writing for all services rendered by it hereunder (which
         compensation shall not be limited by any provision of law in regard to
         the compensation of a trustee of an express trust);





                                       77
<PAGE>   80
                 (2)      except as otherwise expressly provided herein, to
         reimburse the Trustee upon its request for all reasonable expenses,
         disbursements and advances incurred or made by the Trustee in
         accordance with any provision of this Indenture (including the
         reasonable compensation and the expenses and disbursements of its
         agents and counsel), except any such expense, disbursement or advance
         as may be attributable to its negligence or bad faith; and

                 (3)      to indemnify the Trustee for, and to hold it harmless
         against, any and all loss, damage, claim, liability or expense
         incurred without negligence or bad faith on its part, including taxes
         (other than taxes based upon, measured by or determined by the revenue
         or income of the Trustee), arising out of or in connection with the
         acceptance or administration of this trust, including the costs and
         expenses of defending itself against any claim or liability in
         connection with the exercise or performance of any of its powers or
         duties hereunder.

                 The Trustee shall have a lien prior to the Securities as to
all property and funds held by it hereunder for any amount owing to it pursuant
to this Section 607, except with respect to funds held in trust for the benefit
of the Holders of particular Securities.

                 When the Trustee incurs expenses or renders services in
connection with an Event of Default specified in Section 501(8) or Section
501(9), the expenses (including the reasonable charges and expenses of its
counsel) and the compensation for the services are intended to constitute
expenses of administration under any applicable Federal or state bankruptcy,
insolvency or other similar law.

                 The provisions of this Section shall survive any termination
of this Indenture.


SECTION 608.  Conflicting Interests.

                 If the Trustee has or shall acquire a conflicting interest
within the meaning of the Trust Indenture Act, the Trustee shall either
eliminate such interest or resign, to the extent and in the manner provided by,
and subject to the provisions of, the Trust Indenture Act and this Indenture.


SECTION 609.  Corporate Trustee Required; Eligibility.

                 There shall at all times be a Trustee hereunder which shall be
a Person that is eligible pursuant to the Trust Indenture Act to act as such
and has a combined capital and





                                       78
<PAGE>   81
surplus of at least $50,000,000 and its Corporate Trust Office in Chicago,
Illinois or the Borough of Manhattan, The City of New York.  If such Person
publishes reports of condition at least annually, pursuant to law or to the
requirements of said supervising or examining authority, then for the purposes
of this Section and to the extent permitted by the Trust Indenture Act, the
combined capital and surplus of such Person shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published.  If at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section, it shall resign immediately in the manner
and with the effect hereinafter specified in this Article.

SECTION 610.  Resignation and Removal; Appointment of Successor.

                 (a)      No resignation or removal of the Trustee and no
appointment of a successor Trustee pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 611.

                 (b)      The Trustee may resign at any time by giving written
notice thereof to the Company.  If an instrument of acceptance by a successor
Trustee in accordance with the applicable requirements of Section 611 shall not
have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of
competent jurisdiction for the appointment of a successor Trustee.

                 (c)      The Trustee may be removed at any time by Act of the
Holders of a majority in principal amount at Stated Maturity of the Outstanding
Securities, delivered to the Trustee and to the Company.  If an instrument of
acceptance by a successor Trustee in accordance with the applicable
requirements of Section 611 shall not have been delivered to the Trustee within
30 days after the giving of such notice of removal, the Trustee may petition
any court of competent jurisdiction for the appointment of a successor Trustee.

                 (d)      If at any time:

                 (1)      the Trustee shall fail to comply with Section 608
         after written request therefor by the Company or by any Holder who has
         been a bona fide Holder of a Security for at least six months, or

                 (2)      the Trustee shall cease to be eligible under Section
         609 and shall fail to resign after written request therefor by the
         Company or by any such Holder, or





                                       79
<PAGE>   82
                 (3)      the Trustee shall become incapable of acting or shall
         be adjudged a bankrupt or insolvent or a receiver of the Trustee or of
         its property shall be appointed or any public officer shall take
         charge or control of the Trustee or of its property or affairs for the
         purpose of rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee, or (ii) subject to Section 514, any Holder who has been a bona fide
Holder of a Security for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee.

                 (e)      If the Trustee shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of Trustee for
any cause, the Company, by a Board Resolution, shall promptly appoint a
successor Trustee.  If, within one year after such resignation, removal or
incapability, or the occurrence of such vacancy, a successor Trustee shall be
appointed by Act of the Holders of a majority in principal amount at Stated
Maturity of the Outstanding Securities delivered to the Company and the
retiring Trustee, the successor Trustee so appointed shall, forthwith upon its
acceptance of such appointment in accordance with the applicable requirements
of Section 611, become the successor Trustee and supersede the successor
Trustee appointed by the Company.  If no successor Trustee shall have been so
appointed by the Company or the Holders and accepted appointment in accordance
with the applicable requirements of Section 611, any Holder who has been a bona
fide Holder of a Security for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for
the appointment of a successor Trustee.

                 (f)      The Company shall give notice of each resignation and
each removal of the Trustee and each appointment of a successor Trustee to all
Holders in the manner provided in Section 106.  Each notice shall include the
name of the successor Trustee and the address of its Corporate Trust Office.


SECTION 611.  Acceptance of Appointment by Successor.

                 Every successor Trustee appointed hereunder shall execute,
acknowledge and deliver to the Company and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on request of
the Company or the successor Trustee, such retiring





                                       80
<PAGE>   83
Trustee shall, upon payment of its charges, execute and deliver an instrument
transferring to such successor Trustee all the rights, powers and trusts of the
retiring Trustee and shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder.  Upon
request of any such successor Trustee, the Company shall execute any and all
instruments for more fully and certainly vesting in and confirming to such
successor Trustee all such rights, powers and trusts.

                 No successor Trustee shall accept its appointment unless at
the time of such acceptance such successor Trustee shall be qualified and
eligible under this Article.


SECTION 612.    Merger, Conversion, Consolidation or Succession to
                Business.

                 Any corporation into which the Trustee may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Trustee shall be a
party, or any corporation succeeding to all or substantially all the corporate
trust business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto.  In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.


SECTION 613.  Preferential Collection of Claims Against Company.

                 If and when the Trustee shall be or become a creditor of the
Company (or any other obligor upon the Securities), the Trustee shall be
subject to the provisions of the Trust Indenture Act regarding the collection
of claims against the Company (or any such other obligor).


SECTION 614.  Appointment of Authenticating Agent.

                 The Trustee may appoint an Authenticating Agent or Agents
which shall be authorized to act on behalf of the Trustee to authenticate
Securities issued upon original issue and upon exchange, registration of
transfer or partial redemption or partial purchase or pursuant to Section 308,
and Securities so authenticated shall be entitled to the benefits of this
Indenture





                                       81
<PAGE>   84
and shall be valid and obligatory for all purposes as if authenticated by the
Trustee hereunder.  Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent.  Each Authenticating Agent shall be acceptable to the
Company and shall at all times be a corporation organized and doing business
under the laws of the United States of America, any State thereof or the
District of Columbia, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $50,000,000 and
subject to supervision or examination by Federal or State authority.  If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time
an Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

                 Any corporation into which an Authenticating Agent may be
merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which such
Authenticating Agent shall be a party, or any corporation succeeding to the
corporate agency or corporate trust business of an Authenticating Agent, shall
continue to be an Authenticating Agent, provided such corporation shall be
otherwise eligible under this Section, without the execution or filing of any
paper or any further act on the part of the Trustee or the Authenticating
Agent.

                 An Authenticating Agent may resign at any time by giving
written notice thereof to the Trustee and to the Company.  The Trustee may at
any time terminate the agency of an Authenticating Agent by giving written
notice thereof to such Authenticating Agent and to the Company.  Upon receiving
such a notice of resignation or upon such a termination, or in case at any time
such Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give notice of such
appointment in the manner provided in Section 106, to all Holders as their
names and addresses appear in the Security Register. Any successor
Authenticating Agent upon acceptance of its appointment hereunder shall become
vested with all the rights, powers and duties of its predecessor hereunder,
with like effect





                                       82
<PAGE>   85
as if originally named as an Authenticating Agent.  No successor Authenticating
Agent shall be appointed unless eligible under the provisions of this Section.

                 The Company agrees to pay to each Authenticating Agent from
time to time reasonable compensation for its services under this Section.

                 If an appointment is made pursuant to this Section, the
Securities may have endorsed thereon, in addition to the Trustee's certificate
of authentication, an alternative certificate of authentication in the
following form:

                 This is one of the Securities described in the within-
mentioned Indenture.

Holders under this Indenture; provided, however, that no such supplemental

affected thereby,

         any installment of interest on, any Security, or reduce the principal
         amount thereof or the rate of interest thereon or any premium payable
         thereon, or reduce the Default Amount that would be due and payable on

                 (2)      reduce the percentage in principal amount at Stated
         Maturity of the Outstanding Securities, the consent of whose Holders
         is required for any such supplemental indenture, or the consent of
         whose Holders is required for any waiver (of compliance with certain
         provisions of this Indenture or certain defaults hereunder and their
         consequences) provided for in this Indenture, or

                 (3)      modify any of the provisions of this Section, Section
         513 or Section 1018, except to increase any such percentage or to
         provide that certain other provisions of this Indenture cannot be
         modified or waived without the consent of the Holder of each
         Outstanding Security affected thereby, or

                 (4)      modify any provisions of this Indenture relating to
         the calculation of Accreted Value, or

                 (5)      following the mailing of an Offer with respect to an
         Offer to Purchase pursuant to Section 1013, modify the provisions of
         this Indenture with respect to such Offer to Purchase in a manner
         adverse to such Holder.

                 It shall not be necessary for any Act of Holders under this
Section to approve the particular form of any proposed supplemental indenture,
but it shall be sufficient if such Act shall approve the substance thereof.

SECTION 903.  Execution of Supplemental Indentures.

                 In executing, or accepting the additional trusts created by,
any supplemental indenture permitted by this Article or the modifications
thereby of the trusts created by this Indenture, the Trustee shall be entitled
to receive, and (subject to Section 601) shall be fully protected in relying
upon, an Opinion of Counsel stating that the execution of such supplemental
indenture is authorized or permitted by this Indenture.  The Trustee may, but
shall not be obligated to, enter into any such supplemental indenture which
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise.


SECTION 904.  Effect of Supplemental Indentures.

                 Upon the execution of any supplemental indenture under this
Article, this Indenture shall be modified in accordance therewith, and such
supplemental indenture shall form a part of this Indenture for all purposes;
and every Holder of Securities theretofore or thereafter authenticated and
delivered hereunder shall be bound thereby.


SECTION 905.  Conformity with Trust Indenture Act.

                 Every supplemental indenture executed pursuant to this Article
shall conform to the requirements of the Trust Indenture Act.


SECTION 906.  Reference in Securities to Supplemental Indentures.

                 Securities authenticated and delivered after the execution of
any supplemental indenture pursuant to this Article may, and shall if required
by the Trustee, bear a notation in form approved by the Trustee as to any
matter provided for in such supplemental indenture.  If the Company shall so
determine, new Securities so modified as to conform, in the opinion of the
Trustee and the Company, to any such supplemental indenture may be prepared and
executed by the Company and authenticated and delivered by the Trustee in
exchange for Outstanding Securities.

                                  ARTICLE TEN

                                   Covenants

SECTION 1001.  Payment of Principal, Premium and Interest.

                 The Company will duly and punctually pay the principal of (and
premium, if any) and interest on the Securities in accordance with the terms of
the Securities and this Indenture.


SECTION 1002.  Maintenance of Office or Agency.

                 The Company will maintain in the Borough of Manhattan, The
City of New York, an office or agency where Securities may be presented or
surrendered for payment, where Securities may be surrendered for registration
of transfer or exchange and where notices and demands to or upon the Company in
respect of the Securities and this Indenture may be served.  The Company will
give prompt written notice to the Trustee of the location, and any change in
the location, of such office or agency.  If at any time the Company shall fail
to maintain any such required office or agency or shall fail to furnish the
Trustee with the address thereof, such presentations, surrenders, notices and
demands may be made or served at the Corporate Trust Office of the Trustee, and
the Company hereby appoints the Trustee as its agent to receive all such
presentations, surrenders, notices and demands. In the event any such notice or
demands are so made or served on the Trustee, the Trustee will promptly forward
copies thereof to the Company.

                 The Company may also from time to time designate one or more
other offices or agencies (in or outside the Borough of Manhattan, The City of
New York) where the Securities may be presented or surrendered for any or all
such purposes and may from time to time rescind such designations; provided,
however, that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency in the Borough of
Manhattan, The City of New York, for such purposes.  The Company will give
prompt written notice to the Trustee of any such designation or rescission and
of any change in the location of any such other office or agency.


SECTION 1003.  Money for Security Payments to be Held in Trust.

                 If the Company shall at any time act as its own Paying Agent,
it will, on or before each due date of the principal of (and premium, if any)
or interest on any of the Securities, segregate and hold in trust for the
benefit of the Persons entitled thereto a sum sufficient to pay the principal
(and premium, if any) or interest so becoming due until such sums





                                       90
<PAGE>   93
shall be paid to such Persons or otherwise disposed of as herein provided and
will promptly notify the Trustee of its action or failure so to act.

                 Whenever the Company shall have one or more Paying Agents, it
will, prior to each due date of the principal of (and premium, if any) or
interest on any Securities, deposit with a Paying Agent a sum sufficient to pay
the principal (and premium, if any) or interest so becoming due, such sum to be
held as provided by the Trust Indenture Act, and (unless such Paying Agent is
the Trustee) the Company will promptly notify the Trustee of its action or
failure so to act.

                 The Company will cause each Paying Agent other than the
Trustee to execute and deliver to the Trustee an instrument in which such
Paying Agent shall agree with the Trustee, subject to the provisions of this
Section, that such Paying Agent will: (i) comply with the provisions of the
Trust Indenture Act applicable to it as Paying Agent and (ii) during the
continuance of any default by the Company (or any other obligor upon the
Securities) in the making of any payment in respect of the Securities, upon the
written request of the Trustee, forthwith pay to the Trustee all sums held in
trust by such Paying Agent as such.

                 The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held
in trust by the Company or such Paying Agent, such sums to be held by the
Trustee upon the same trusts as those upon which such sums were held by the
Company or such Paying Agent; and, upon such payment by any Paying Agent to the
Trustee, such Paying Agent shall be released from all further liability with
respect to such money.

                 Any money deposited with the Trustee or any Paying Agent, or
then held by the Company, in trust for the payment of the principal of (and
premium, if any) or interest on any Security and remaining unclaimed for two
years after such principal (and premium, if any) or interest has become due and
payable shall be paid to the Company on Company Request, or (if then held by
the Company) shall be discharged from such trust; and the Holder of such
Security shall thereafter, as an unsecured general creditor, look only to the
Company for payment thereof, and all liability of the Trustee or such Paying
Agent with respect to such trust money, and all liability of the Company as
trustee thereof, shall thereupon cease; provided, however, that the Trustee or
such Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once, in a newspaper published in
the English language, customarily published on each Business Day and of general
circulation in The City of New York, notice that such money remains unclaimed
and that, after a date specified therein, which





                                       91
<PAGE>   94
shall not be less than 30 days from the date of such publication, any unclaimed
balance of such money then remaining will be repaid to the Company.


SECTION 1004.  Existence.

                 Subject to Article Eight, the Company will do or cause to be
done all things necessary to preserve and keep in full force and effect its
existence, rights (charter and statutory) and material franchises; provided,
however, that the Company shall not be required to preserve any such right or
franchise if the Board of Directors in good faith shall determine that the
preservation thereof is no longer desirable in the conduct of the business of
the Company and that the loss thereof is not disadvantageous in any material
respect to the Holders.


SECTION 1005.  Maintenance of Properties.

                 The Company will cause all material properties used or useful
in the conduct of its business or the business of any Restricted Subsidiary to
be maintained and kept in good condition, repair and working order and supplied
with all necessary equipment and will cause to be made all necessary repairs,
renewals, replacements, betterments and improvements thereof, all as in the
judgment of the Company may be necessary so that the business carried on in
connection therewith may be properly and advantageously conducted at all times;
provided, however, that nothing in this Section shall prevent the Company from
discontinuing the operation or maintenance of any of such material properties
if such discontinuance is, as determined by the Board of Directors in good
faith, desirable in the conduct of its business or the business of any
Restricted Subsidiary and not disadvantageous in any material respect to the
Holders.


SECTION 1006.  Payment of Taxes and Other Claims.

                 The Company will pay or discharge or cause to be paid or
discharged, before the same shall become delinquent,  (1) all taxes,
assessments and governmental charges levied or imposed upon the Company or any
of its Restricted Subsidiaries or upon the income, profits or property of the
Company or any of its Restricted Subsidiaries, and (2) all lawful claims for
labor, materials and supplies which, if unpaid, might by law become a lien upon
the property of the Company or any of its Restricted Subsidiaries; provided,
however, that the Company shall not be required to pay or discharge or cause to
be paid or discharged any such tax, assessment, charge or claim whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings.





                                       92
<PAGE>   95
SECTION 1007.  Maintenance of Insurance.

                 The Company shall, and shall cause its Restricted Subsidiaries
to, keep at all times all of their properties which are of an insurable nature
insured against loss or damage with insurers believed by the Company to be
responsible to the extent that property of similar character is usually so
insured by corporations similarly situated and owning like properties in
accordance with good business practice.  The Company shall, and shall cause its
Restricted Subsidiaries to, use the proceeds from any such insurance policy to
repair, replace or otherwise restore all material properties to which such
proceeds relate, provided, however, that the Company shall not be required to
repair, replace or otherwise restore any such material property if the Board of
Directors in good faith determines that such inaction is desirable in the
conduct of the business of the Company or any Restricted Subsidiary and not
disadvantageous in any material respect to the Holders.


SECTION 1008.  Limitation on Consolidated Debt.

         The Company shall not, and shall not permit any Restricted Subsidiary
to, Incur any Debt (including Acquired Debt), other than Permitted Debt, unless
(i) with respect to Debt Incurred under this clause (i), the Debt so Incurred
and outstanding is in an aggregate principal amount that does not exceed 2.25
times, with respect to Capital Stock sales after June 1, 1997 and on or prior
to March 31, 1998, or 2.00 times, with respect to Capital Stock sales after
March 31, 1998, the aggregate amount of net cash proceeds (or 80% of the Fair
Market Value of property other than cash) received by the Company after June 1,
1997 from the issuance and sale (other than to a Restricted Subsidiary) of
shares of its Capital Stock (other than Redeemable Stock), or any options,
warrants or other rights to purchase such Capital Stock (other than Redeemable
Stock), other than (x) proceeds applied for use as a Directed Investment
(unless such designation has been revoked by the Board of Directors and the
Company either abandons its plans to make such Investment or is able to make
such Investment pursuant to Section 1009 (other than as a Directed Investment))
and (y) proceeds which have been included in the computation of the amounts
available for Restricted Payments pursuant to clause (c)(2) of Section 1009, to
the extent the inclusion thereof was necessary to allow a subsequent Restricted
Payment to be made, or (ii) on the date of such Incurrence, after giving effect
to the Incurrence of such Debt (or Acquired Debt) and the receipt and
application of the net proceeds thereof (and, if the net proceeds of such new
Debt are used to acquire a Person that becomes a Restricted Subsidiary or an
operating business of the Company or a Restricted Subsidiary, to all terms of
such acquisition) on a pro forma basis, the





                                       93
<PAGE>   96
Operating Cash Flow to Consolidated Interest Expense Ratio would equal or
exceed 1.75 to 1.


SECTION 1009.  Limitation on Restricted Payments.

         The Company shall not, directly or indirectly:

                 (i)  declare or pay any dividend on, or make any distribution
         to the holders of, any shares of its Capital Stock (other than
         dividends or distributions payable solely in its Capital Stock (other
         than Redeemable Stock) or in options, warrants or other rights to
         purchase any such Capital Stock (other than Redeemable Stock));

                 (ii)  purchase, redeem or otherwise acquire or retire for
         value, or permit any Restricted Subsidiary to, directly or indirectly,
         purchase, redeem or otherwise acquire or retire for value (other than
         value consisting solely of Capital Stock of the Company that is not
         Redeemable Stock or options, warrants or other rights to acquire such
         Capital Stock that is not Redeemable Stock), any Capital Stock of the
         Company (including options, warrants or other rights to acquire such
         Capital Stock);

                 (iii)  redeem, repurchase, defease or otherwise acquire or
         retire for value, or permit any Restricted Subsidiary to, directly or
         indirectly, redeem, repurchase, defease or otherwise acquire or retire
         for value (other than value consisting solely of Capital Stock of the
         Company that is not Redeemable Stock or options, warrants or other
         rights to acquire such Capital Stock that is not Redeemable Stock),
         prior to any scheduled maturity, scheduled repayment or scheduled
         sinking fund payment, any Debt that is subordinate (whether pursuant
         to its terms or by operation of law) in right of payment to the
         Securities; or

                 (iv)  make, or permit any Restricted Subsidiary, directly or
         indirectly, to make, any Investment (other than any Permitted
         Investment) in any Person (other than in a Restricted Subsidiary or a
         Person that becomes a Restricted Subsidiary as a result of such
         Investment);

(each of the foregoing actions set forth in clauses (i) through (iv), other
than any such action that is a Permitted Investment or a Permitted
Distribution, being referred to as a "Restricted Payment") unless, at the time
of such Restricted Payment, and after giving effect thereto:





                                       94
<PAGE>   97
                 (a)  no Default or Event of Default shall have occurred and be
         continuing;

                 (b)  except with respect to Investments, after giving effect,
         on a pro forma basis, to such Restricted Payment and the Incurrence of
         any Debt the net proceeds of which are used to finance such Restricted
         Payment, the Consolidated Debt to Annualized Operating Cash Flow Ratio
         would not have exceeded 7.0 to 1; and

                 (c)  after giving effect to such Restricted Payment on a pro
         forma basis, the aggregate amount of all Restricted Payments made on
         or after February 15, 1994 shall not exceed:

                          (1)  50% of the Consolidated Net Income (or, in the
                 case of a Consolidated Net Loss, minus 100% of such deficit)
                 of the Company for the period (taken as one accounting period)
                 from April 1, 1994 to the last day of the last fiscal quarter
                 preceding the date of the proposed Restricted Payment, plus

                          (2)  the aggregate net proceeds, including the fair
                 market value of property other than cash (as determined by the
                 Board of Directors, whose good faith determination shall be
                 conclusive and evidenced by a Board Resolution), received by
                 the Company from the issuance and sale (other than to a
                 Restricted Subsidiary) on or after February 15, 1994 of shares
                 of its Capital Stock (other than Redeemable Stock), or any
                 options, warrants or other rights to purchase such Capital
                 Stock (other than Redeemable Stock), other than (x) (except
                 for purposes of determining whether an Investment under clause
                 (iv) above is permitted) shares of Capital Stock or options,
                 warrants or other rights to purchase Capital Stock (or shares
                 issuable upon exercise thereof) issued or sold in the
                 PowerFone Merger, Questar/AMI Share Exchanges, Motorola
                 Business Acquisition and NTT transactions as defined and
                 described in the Company's prospectus, dated February 9, 1994,
                 relating to the Company's Senior Redeemable Discount Notes due
                 2004 and (y) shares of Capital Stock or options, warrants or
                 other rights to purchase Capital Stock (or shares issuable
                 upon exercise thereof), the proceeds of the issuance of which
                 is used (A) to make a Directed Investment (unless such
                 designation has been revoked by the Board of Directors and the
                 Company is able to make such Investment pursuant to this
                 Section 1009 (other than as a Directed Investment)) or (B) to
                 Incur Debt under clause (i) of Section 1008 (unless and until
                 the amount of any such Debt (I) is treated as newly issued
                 Debt

                 and could be Incurred in accordance with the Section 1008
                 (other than under clause (i) thereof) or (II) has been repaid
                 or refinanced with the proceeds of Debt Incurred in accordance
                 with Section 1008 (other than under clause (i) thereof) or
                 (III) has otherwise been repaid), plus

                          (3)  the aggregate net proceeds, including the fair
                 market value of property other than cash (as determined by the
                 Board of Directors, whose good faith determination shall be
                 conclusive and evidenced by a Board Resolution), received by
                 the Company from the issuance or sale (other than to a
                 Restricted Subsidiary) after February 15, 1994 of any Capital
                 Stock of the Company (other than Redeemable Stock), or any
                 options, warrants or other rights to purchase such Capital
                 Stock (other than Redeemable Stock), upon the conversion of,
                 or exchange for, Debt of the Company or a Restricted
                 Subsidiary.

         The foregoing limitations in this Section 1009 do not limit or
restrict the making of any Permitted Distribution, Permitted Investment or
Directed Investment, and none of a Permitted Distribution, Permitted Investment
or Directed Investment shall be counted as a Restricted Payment for purposes of
clause (c) above.  In addition, the foregoing limitations do not prevent the
Company from (I) paying a dividend on Capital Stock of the Company within 60
days after the declaration thereof if, on the date when the dividend was
declared, the Company could have paid such dividend in accordance with the
provisions of this Indenture, (II) repurchasing Capital Stock of the Company
(including options, warrants or other rights to acquire such Capital Stock)
from employees or former employees of the Company or any Subsidiary thereof for
consideration not to exceed $500,000 in the aggregate in any fiscal year (with
repurchases pursuant to this clause (II) not being counted as Restricted
Payments for purposes of clause (c) above) or (III) the repurchase, redemption
or other acquisition for value of Capital Stock of the Company to the extent
necessary to prevent the loss or secure the renewal or reinstatement of any
license or franchise held by the Company or any of its Subsidiaries from any
governmental agency; or (IV) Investments in Unrestricted Subsidiary Funding
Company so long as (x) such Investments are invested in Nextel International,
Inc. and (y) Nextel International, Inc. is a Subsidiary of the Company.

         Notwithstanding the foregoing limitations in this Section 1009, the
Company will be permitted to make any Investment in a Person that is not
(either before or after giving effect thereto) a Subsidiary of the Company,
provided that, immediately after giving effect thereto, the amount equal to (a)
the aggregate amount of all Investments made pursuant to this





                                       96
<PAGE>   99
paragraph minus (b) all cash received by the Company or any Restricted
Subsidiary from the sale, transfer or other disposition to a Person that is not
a Subsidiary of the Company of any such Investment (or portion thereof)
included in such aggregate amount (with the amount of cash to be counted for
this purpose not to exceed the amount of such Investment (or portion thereof)
so included), shall not exceed the greater of (i) $250 million and (ii) 2% of
the Total Market Value of Equity of the Company as of such time.  For purposes
of determining the aggregate amount of Investments referred to in clause (a),
the amount of any Investment shall be deemed to equal the cash portion thereof
plus the fair market value of any non-cash portion thereof (to the extent such
portion constitutes an Investment) at the time such Investment is made, as
determined by the Board of Directors (whose good faith determination shall be
conclusive and evidenced by a Board Resolution).

         Notwithstanding the foregoing, no Investment in a Person that
immediately thereafter would be a Restricted Subsidiary will be a Restricted
Payment.  In addition, if any Person in which an Investment is made, which
Investment constitutes a Restricted Payment when made, thereafter becomes a
Restricted Subsidiary, all such Investments previously made in such Person
shall no longer be counted as Restricted Payments for purposes of calculating
the aggregate amount of Restricted Payments pursuant to clause (c) of the third
preceding paragraph or the aggregate amount of Investments pursuant to clause
(a) of the immediately preceding paragraph, in each case to the extent such
Investments would otherwise be so counted.

         For purposes of clause (c)(3) above, the net proceeds received by the
Company from the issuance or sale of its Capital Stock either upon the
conversion of, or exchange for, Debt of the Company or any Restricted
Subsidiary shall be deemed to be an amount equal to (a) the sum of (i) the
principal amount or accreted value (whichever is less) of such Debt on the date
of such conversion or exchange and (ii) the additional cash consideration, if
any, received by the Company upon such conversion or exchange, less any payment
on account of fractional shares, minus (b) all expenses incurred in connection
with such issuance or sale.  In addition, for purposes of clause (c)(3) above,
the net proceeds received by the Company from the issuance or sale of its
Capital Stock upon the exercise of any options or warrants of the Company or
any Restricted Subsidiary shall be deemed to be an amount equal to (a) the
additional cash consideration, if any, received by the Company upon such
exercise, minus (b) all expenses incurred in connection with such issuance or
sale.

         For purposes of this Section 1009, if a particular Restricted Payment
involves a non-cash payment, including a distribution of assets, then such
Restricted Payment shall be





                                       97
<PAGE>   100
deemed to be an amount equal to the cash portion of such Restricted Payment, if
any, plus an amount equal to the fair market value of the non-cash portion of
such Restricted Payment, as determined by the Board of Directors (whose good
faith determination shall be conclusive and evidenced by a Board Resolution).


SECTION 1010.  Restricted Subsidiaries.

         The Company shall not designate any Restricted Subsidiary as an
Unrestricted Subsidiary, and shall not itself, and shall not permit any
Restricted Subsidiary to, sell, convey, transfer or otherwise dispose of any
assets, other than in the ordinary course of business, to any Unrestricted
Subsidiary or any Person that becomes an Unrestricted Subsidiary as part of
such transaction, unless, after giving effect to any such action, the assets
(not including any assets so sold, conveyed, transferred or otherwise disposed
of, other than in the ordinary course of business, to any Unrestricted
Subsidiary or any Person that becomes an Unrestricted Subsidiary as part of
such transaction) and business of the Company and its remaining Restricted
Subsidiaries generated at least 90% of Digital Mobile-SMR Operating Cash Flow
in the fiscal quarter of the Company most recently completed prior to the date
of such action.

         The Board of Directors may designate any existing Unrestricted
Subsidiary or any Person that is about to become a Subsidiary of the Company as
a Restricted Subsidiary if, after giving effect to such action (and, if such
designation is made in connection with the acquisition of a Person or an
operating business that is about to become a Subsidiary of the Company, after
giving effect to all terms of such acquisition) on a pro forma basis, on the
date of such action, the Debt, if any, of such Unrestricted Subsidiary or
Person outstanding immediately prior to such designation would have been
permitted to be Incurred (and shall be deemed to have been Incurred) for all
purposes of this Indenture.

         Subject to the second preceding paragraph and compliance with Section
1009, the Board of Directors may designate any Restricted Subsidiary as an
Unrestricted Subsidiary.

         The designation by the Board of Directors of a Restricted Subsidiary
as an Unrestricted Subsidiary shall, for all purposes of Section 1009
(including clause (b) thereof), be deemed to be a Restricted Payment of an
amount equal to the fair market value of the Company's ownership interest in
such Subsidiary (including, without duplication, such indirect ownership
interest in all Subsidiaries of such Subsidiary), as determined by the Board of
Directors in good faith and evidenced by a Board Resolution.

         Notwithstanding the foregoing provisions of this Section 1010, the
Board of Directors may not designate a Subsidiary of the Company to be an
Unrestricted Subsidiary if, after such designation, (a) the Company or any of
its other Restricted Subsidiaries (i) provides credit support for, or a
Guarantee of, any Debt of such Subsidiary (including any undertaking, agreement
or instrument evidencing such Debt) or (ii) is directly or indirectly liable
for any Debt of such Subsidiary, (b) a default with respect to any Debt of such
Subsidiary (including any right which the holders thereof may have to take
enforcement action against such Subsidiary) would permit (upon notice, lapse of
time or both) any holder of any other Debt of the Company or any Restricted
Subsidiary to declare a default on such other Debt or cause the payment thereof
to be accelerated or payable prior to its final scheduled maturity or (c) such
Subsidiary owns any Capital Stock of, or owns or holds any Lien on any property
of, any Restricted Subsidiary which is not a Subsidiary of the Subsidiary to be
so designated.

         The Board of Directors, from time to time, may designate any Person
that is about to become a Subsidiary of the Company as an Unrestricted
Subsidiary, and may designate any newly-created Subsidiary as an Unrestricted
Subsidiary, if at the time such Subsidiary is created it contains no assets
(other than such de minimis amount of assets then required by law for the
formation of corporations) and no Debt.  Subsidiaries of the Company that are
not designated by the Board of Directors as Restricted or Unrestricted
Subsidiaries shall be deemed to be Restricted Subsidiaries.  Notwithstanding
any provisions of this Section 1010, all Subsidiaries of an Unrestricted
Subsidiary shall be Unrestricted Subsidiaries.  The Board of Directors shall
not change the designation of a Subsidiary of the Company more than twice in
any period of five years.


SECTION 1011.  Transactions with Affiliates.

         The Company shall not, and shall not permit any Restricted Subsidiary
to, directly or indirectly, enter into any transaction (including the purchase,
sale, lease or exchange of any property or the rendering of any service) or
series of related transactions with any Affiliate of the Company on terms that
are less favorable to the Company or such Restricted Subsidiary, as the case
may be, than those which might be obtained at the time of such transaction from
a Person that is not such an Affiliate; provided, however, that this Section
1011 shall not limit, or be applicable to, (i) any transaction between
Unrestricted Subsidiaries not involving the Company or any Restricted
Subsidiary, (ii) any transaction between the Company and any Restricted
Subsidiary or between Restricted Subsidiaries or (iii) any Permitted
Transactions.  In addition, any transaction or series of related transactions,
other than Permitted





                                       99
<PAGE>   102
Transactions, between the Company or any Restricted Subsidiary and any
Affiliate of the Company (other than a Restricted Subsidiary) involving an
aggregate consideration of $5 million or more must be approved in good faith by
a majority of the Company's Disinterested Directors (of which there must be at
least one) and evidenced by a Board Resolution.  For purposes of this Section
1011, any transaction or series of related transactions between the Company or
any Restricted Subsidiary and an Affiliate of the Company that is approved by a
majority of the Disinterested Directors (of which there must be at least one)
and evidenced by a Board Resolution shall be deemed to be on terms as favorable
as those that might be obtained at the time of such transaction (or series of
transactions) from a Person that is not such an Affiliate and thus shall be
permitted under this Section 1011.


SECTION 1012.  [Intentionally Omitted]


SECTION 1013.  Change of Control.

         Upon the occurrence of a Change of Control, the Company shall be

prior to October 31, 2002 or 101% of the principal amount thereof, plus accrued
and unpaid interest, if any, to any Purchase Date on and after October 31,
2002.  The Offer to Purchase must be made within 30 days following a Change of
Control, must remain open for at least 30 and not more than 60 days and must
comply with the requirements of Rule 14e-1 under the Exchange Act and any other
applicable securities laws and regulations.

SECTION 1015.   Activities of the Company and Restricted
                Subsidiaries.

         The Company shall not, and shall not permit any Restricted Subsidiary
to, engage in any business other than the telecommunications business and
related activities and services, including such businesses, activities and
services as the Company and the Restricted Subsidiaries are engaged in on the
Closing Date.

the Commission the annual reports, quarterly reports and other documents which
the Company would have been required to file with the Commission pursuant to
such Section 13(a) or 15(d) or any successor provision thereto if the Company
were subject thereto, such documents to be filed with the Commission on or

annual reports, quarterly reports and other documents which the Company would
have been required to file with the Commission pursuant to Section 13(a) or
15(d) of the Exchange Act or any successor provisions thereto if the Company
were subject thereto and (b) if filing such documents by the Company with the
Commission is not permitted under the Exchange Act, promptly upon written
request supply copies of such documents to any prospective Holder.  The
Trustee's receipt of such reports, information and documents shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein.


SECTION 1017.   Statement by Officers as to Default; Compliance
                Certificates.

                 (a)      The Company shall deliver to the Trustee, within 120
days after the end of each fiscal year of the Company ending after the date
hereof an Officers' Certificate, stating whether or not to the best knowledge
of the signers thereof the Company is in default in the performance and
observance of any of the terms, provisions and conditions of this Indenture
(without regard to any period of grace or requirement of notice provided
hereunder), and if the Company shall be in default, specifying all such
defaults and the nature and status thereof of which they may have knowledge.

                 (b)      The Company shall deliver to the Trustee, as soon as
possible and in any event within 10 days after the Company becomes aware of the
occurrence of a Default or an Event of Default, an Officers' Certificate
setting forth the details of such Default or Event of Default, and the action
which the Company proposes to take with respect thereto.

SECTION 1018.  Waiver of Certain Covenants.

                 The Company may omit in any particular instance to comply with
any covenant or condition set forth in Section 801, provided pursuant to
Section 901(2) and set forth in Sections 1004 to 1016, inclusive, if before the
time for such compliance the Holders of at least a majority in principal amount
at Stated Maturity of the Outstanding Securities shall, by Act of such Holders,
either waive such compliance in such instance or generally waive compliance
with such covenant or condition, but no such waiver shall extend to or affect
such covenant or condition except to the extent so expressly waived, and, until
such waiver shall become effective, the obligations of the Company and the
duties of the Trustee in respect of any such covenant or condition shall remain
in full force and effect; provided, however, with respect to an Offer to
Purchase as to which an Offer has been mailed, no such waiver may be made or
shall be effective against any Holder tendering Securities pursuant to such
Offer, and the Company may not omit to comply with the terms of such Offer as
to such Holder.


SECTION 1019.  Company to Supply Information Concerning
               Original Issue Discount.

                 The Company shall provide to the Trustee on a timely basis

Service and the Holders of the Securities relating to original issue discount,
including without limitation, Form 1099-OID or any successor form.

                 On or after October 31, 2004, the Company may redeem the
Securities at a Redemption Price equal to 100% of the principal amount at
maturity thereof, together in the case of any such redemption with accrued

Stated Maturity is on or prior to such Redemption Date will be payable to the
Holders of such Securities, or one or more Predecessor Securities, of record at
the close of business on the relevant Record Dates for the payment of such
interest installments.

                 In addition to any redemption provided for in the immediately
preceding paragraphs, in the event of the sale by the Company after the Closing
Date and prior to October 31, 2000 of its Capital Stock (other than Redeemable
Stock) in a single transaction or series of transactions for an aggregate
purchase price equal to or exceeding $125 million, up to a maximum of 33 1/3%
of the aggregate Accreted Value of the Outstanding Securities will, within 180
days of such sale, at the option of the Company, upon not less than 30 nor more
than 60 days' notice by mail, be redeemable from the net proceeds thereof (but
only to the extent such proceeds consist of cash or readily marketable cash
equivalents received in respect of the Company's Capital Stock so sold, in each
case net of all commissions, discounts, fees, expenses and taxes incurred in
respect thereof) at a Redemption Price equal to 9.75% of the Accreted Value of
the Securities to be redeemed to the Redemption Date.

                 Redemption of Securities at the election of the Company, as

SECTION 1103.  Election to Redeem; Notice to Trustee.

                 The election of the Company to redeem any Securities pursuant
to Section 1101 shall be evidenced by a Board Resolution.  In case of any
redemption at the election of the Company pursuant to Section 1101, the Company
shall, at least 60 days prior to the Redemption Date fixed by the Company
(unless a shorter notice shall be satisfactory to the Trustee), notify the
Trustee of such Redemption Date and of the principal amount of Securities to be

SECTION 1104.  Selection by Trustee of Securities to Be Redeemed.

                 In the case of any partial redemption, selection of the
Securities for redemption will be made by the Trustee in compliance with the
requirements of the principal national securities exchange, if any, on which
the Securities are listed or, if the Securities are not listed on a national
securities exchange, on a pro rata basis, by lot or by such other method as the
Trustee in its sole discretion shall deem to be fair and appropriate; provided
that no Security of $1,000 in principal amount or less shall be redeemed in
part.

                 The Trustee shall promptly notify the Company and each
Security Registrar in writing of the Securities selected for redemption and, in
the case of any Securities selected for partial redemption, the principal
amount thereof to be redeemed.

                 For all purposes of this Indenture and of the Securities,
unless the context otherwise requires, all provisions relating to the
redemption of Securities shall relate, in the case of any Securities redeemed
or to be redeemed only in part, to the portion of the principal amount of such
Securities which has been or is to be redeemed.


SECTION 1105.  Notice of Redemption.

                 Notice of redemption shall be given by first-class mail,
postage prepaid, mailed not less than 30 nor more than 60 days prior to the
Redemption Date, to each Holder of Securities to be redeemed, at his address
appearing in the Security Register.

                 All notices of redemption shall state (including CUSIP, CINS
and ISIN numbers, if any):

                 (1)      the Redemption Date,

                 (2)      the Redemption Price,

                 (3)      if less than all the Outstanding Securities are to be
         redeemed, the identification (and, in the case of partial redemption,
         the principal amounts) of the particular Securities to be redeemed,
         including CUSIP, CINS and ISIN numbers,

                 (4)  that on the Redemption Date the Redemption Price will
         become due and payable upon each such Security to be redeemed and (i)
         that, in the case of a Redemption Date on or after October 31, 2002,
         cash interest thereon will cease to accrue on and after said
         Redemption Date and (ii) that, in the case of a Redemption Date prior
         to October 31, 2002,





                                      104
<PAGE>   107
         the Accreted Value thereof will not increase after said Redemption
         Date,

                 (5) the place or places where such Securities are to be
         surrendered for payment of the Redemption Price, and

                 (6) if the redemption is being made pursuant to the provisions
         of the Securities set forth in the third paragraph of Section 203, a
         brief description of the nature and amount of Capital Stock sold by
         the Company, the aggregate purchase price thereof and the net cash
         proceeds therefrom available for such redemption, the date or dates on
         which such sale was completed and the percentage of the aggregate
         Accreted Value of Outstanding Securities being redeemed.

                 Notice of redemption of Securities to be redeemed at the
election of the Company shall be given by the Company or, at the Company's
request, by the Trustee in the name and at the expense of the Company and shall
be irrevocable.


SECTION 1106.  Deposit of Redemption Price.

                 Prior to any Redemption Date, the Company shall deposit with
the Trustee or with a Paying Agent (or, if the Company is acting as its own
Paying Agent, segregate and hold in trust as provided in Section 1003) an
amount of money sufficient to pay the Redemption Price of, and (except if the
Redemption Date shall be an Interest Payment Date) any applicable accrued
interest on, all the Securities which are to be redeemed on that date.


SECTION 1107.  Securities Payable on Redemption Date.

                 Notice of redemption having been given as aforesaid, the
Securities so to be redeemed shall, on the Redemption Date, become due and
payable at the Redemption Price therein specified, and from and after such date
(unless the Company shall default in the payment of the Redemption Price and
any applicable accrued interest) such Securities shall not bear interest and
the Accreted Value of such Securities shall thereupon and thereafter
conclusively be deemed to be their Accreted Value determined on and as of such
Redemption Date.  Upon surrender of any such Security for redemption in
accordance with said notice, such Security shall be paid by the Company at the
Redemption Price, together with any applicable accrued and unpaid interest to
the Redemption Date; provided, however, that installments of interest whose
Stated Maturity is on or prior to the Redemption Date shall be payable to the
Holders of such Securities, or one or more Predecessor Securities, registered
as such at the close of





                                      105
<PAGE>   108
business on the relevant Record Dates according to their terms and the
provisions of Section 309.

                 If any Security called for redemption in accordance with the
election of the Company made pursuant to Section 1101 shall not be so paid upon
surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate provided by the
Security.


SECTION 1108.  Securities Redeemed in Part.

                 Any Security which is to be redeemed only in part shall be
surrendered at an office or agency of the Company designated for that purpose
pursuant to Section 1002 (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing), and the Company shall execute, and the Trustee
shall authenticate and deliver to the Holder of such Security without service
charge, a new Security or Securities, of any authorized denomination as
requested by such Holder, in aggregate principal amount at Stated Maturity
equal to and in exchange for the unredeemed portion of the principal amount at
Stated Maturity of the Security so surrendered.

SECTION 1201.   Company's Option to Effect Defeasance or Covenant
                Defeasance.

                 The Company may elect, at its option at any time, to have
Section 1202 or Section 1203 applied to the Outstanding Securities (as a whole
and not in part) upon compliance with the conditions set forth below in this
Article.  Any such election shall be evidenced by a Board Resolution.


SECTION 1202.  Defeasance and Discharge.

                 Upon the Company's exercise of its option to have this Section
applied to the Outstanding Securities (as a whole and not in part), the Company
shall be deemed to have been discharged from its obligations with respect to
such Securities as provided in this Section on and after the date the
conditions set forth in Section 1204 are satisfied (hereinafter called
"Defeasance"), and thereafter such Securities shall not be subject to
redemption pursuant thereto.  For this purpose, such Defeasance means that the
Company shall be deemed to have paid and discharged the





                                      106
<PAGE>   109
entire indebtedness represented by such Securities and to have satisfied all
its other obligations under such Securities and this Indenture insofar as such
Securities are concerned (and the Trustee, at the expense of the Company, shall
execute proper instruments acknowledging the same), subject to the following
which shall survive until otherwise terminated or discharged hereunder: (1) the
rights of Holders of such Securities to receive, solely from the trust fund
described in Section 1204 and as more fully set forth in such Section, payments
in respect of the principal of and any premium and interest on such Securities
when payments are due, (2) the Company's obligations with respect to such
Securities under Sections 304, 305, 308, 1002 and 1003, (3) the rights, powers,
trusts, duties and immunities of the Trustee hereunder and (4) this Article.
Subject to compliance with this Article, the Company may exercise its option to
have this Section applied to the Outstanding Securities (as a whole and not in
part) notwithstanding the prior exercise of its option to have Section 1203
applied to such Securities.


SECTION 1203.  Covenant Defeasance.

                 Upon the Company's exercise of its option to have this Section
applied to the Outstanding Securities (as a whole and not in part), (1) the
Company shall be released from its obligations under Section 801(iii), Sections
1005 through 1016, inclusive, and any covenant provided pursuant to Section
901(2) and (2) the occurrence of any event specified in Section 501(4) (with
respect to Section 801(iii)), Section 501(5) (with respect to any of Sections
1005 through 1016, inclusive, and any such covenants provided pursuant to
Section 901(2)), Section 501(6) or Section 501(7) shall be deemed not to be or
result in an Event of Default, in each case with respect to such Securities as
provided in this Section on and after the date the conditions set forth in
Section 1204 are satisfied (hereinafter called "Covenant Defeasance").  For
this purpose, such Covenant Defeasance means that, with respect to such
Securities, the Company may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such specified
Section (to the extent so specified in the case of Sections 501(4) and 501(5)),
whether directly or indirectly by reason of any reference elsewhere herein to
any such Section or by reason of any reference in any such Section to any other
provision herein or in any other document, but the remainder of this Indenture
and such Securities shall be unaffected thereby.

SECTION 1204.  Conditions to Defeasance or Covenant Defeasance.

                 The following shall be the conditions to the application of
Section 1202 or Section 1203 to the Outstanding Securities:

                 (1)      The Company shall irrevocably have deposited or
         caused to be deposited with the Trustee (or another trustee which
         satisfies the requirements contemplated by Section 609 and agrees to
         comply with the provisions of this Article applicable to it) as trust
         funds in trust for the purpose of making the following payments,
         specifically pledged as security for, and dedicated solely to, the
         benefits of the Holders of such Securities, (A) money in an amount, or
         (B) U.S.  Government Obligations which through the scheduled payment
         of principal and interest in respect thereof in accordance with their
         terms will provide, not later than one day before the due date of any
         payment, money in an amount, or (C) a combination thereof, in each
         case sufficient, in the opinion of a nationally recognized firm of

         shall be applied by the Trustee (or any such other qualifying trustee)
         to pay and discharge, the principal of and any installment of interest
         on such Securities on the respective Stated Maturities thereof, in
         accordance with the terms of this Indenture and such Securities.  As
         used herein, "U.S. Government Obligation" means (x) any security which

         which, in either case (i) or (ii), is not callable or redeemable at
         the option of the issuer thereof, and (y) any depository receipt

                 (2)      In the event of an election to have Section 1202
         apply to the Outstanding Securities, the Company shall have delivered
         to the Trustee an Opinion of Counsel stating that (A) the Company has
         received from, or there has been published by, the Internal Revenue
         Service a ruling or (B) since the Closing Date there has been a change
         in the applicable Federal income tax law, in either case (A) or (B) to
         the effect that, and based thereon such opinion shall confirm that,
         the Holders of such Securities will not recognize gain or loss for
         Federal income tax purposes as a result of the deposit, Defeasance and
         discharge to be effected with respect to such Securities and will be
         subject to Federal income tax on the same amount, in the same manner
         and at the same times as would be the case if such deposit, Defeasance
         and discharge were not to occur.

                 (3)      In the event of an election to have Section 1203
         apply to the Outstanding Securities, the Company shall have delivered
         to the Trustee an Opinion of Counsel to the effect that the Holders of
         such Securities will not recognize gain or loss for Federal income tax
         purposes as a result of the deposit and Covenant Defeasance to be
         effected with respect to such Securities and will be subject to
         Federal income tax on the same amount, in the same manner and at the
         same times as would be the case if such deposit and Covenant
         Defeasance were not to occur.

                 (4)      No Default with respect to the Outstanding Securities
         shall have occurred and be continuing at the time of such deposit or,
         with regard to any such event specified in Sections 501(8) and (9), at
         any time on or prior to the 90th day after the date of such deposit
         (it being understood that this condition shall not be deemed satisfied
         until after such 90th day).

                 (5)      Such Defeasance or Covenant Defeasance shall not
         cause the Trustee to have a conflicting interest within the meaning of
         the Trust Indenture Act (assuming all Securities are in default within
         the meaning of such Act).

                 (6)      Such Defeasance or Covenant Defeasance shall not
         result in a breach or violation of, or constitute a default under, any
         other agreement or instrument to which the Company is a party or by
         which it is bound.

                 (7)      Such Defeasance or Covenant Defeasance shall not
         result in the trust arising from such deposit constituting an
         investment company within the meaning of the Investment Company Act
         unless such trust shall be registered under such Act or exempt from
         registration thereunder.

                 (8)      The Company shall have delivered to the Trustee an
         Officers' Certificate and an Opinion of Counsel, each stating that all

         Defeasance have been complied with.


SECTION 1205.   Deposited Money and U.S. Government Obligations to
                Be Held in Trust; Miscellaneous Provisions.

                 Subject to the provisions of the last paragraph of Section
1003, all money and U.S. Government Obligations (including the proceeds
thereof) deposited with the Trustee or other qualifying trustee (solely for
purposes of this Section and Section 1206, the Trustee and any such other
trustee are referred to collectively as the "Trustee") pursuant to Section 1204
in respect of the Outstanding Securities shall be held in trust and applied by
the Trustee, in accordance with the provisions of such Securities and this
Indenture, to the payment, either directly or through any such Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities, of all sums due and to become due
thereon in respect of principal and any premium and interest, but money so held
in trust need not be segregated from other funds except to the extent required
by law.

                 The Company shall pay and indemnify the Trustee against any
tax, fee or other charge imposed on or assessed against the U.S. Government
Obligations deposited pursuant to Section 1204 or the principal and interest
received in respect thereof other than any such tax, fee or other charge which
by law is for the account of the Holders of Outstanding Securities.

                 Anything in this Article to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or U.S. Government Obligations held by it as provided in
Section 1204 which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect the Defeasance or Covenant Defeasance, as
the case may be, with respect to the Outstanding Securities.


SECTION 1206.  Reinstatement.

                 If the Trustee or the Paying Agent is unable to apply any
money in accordance with this Article with respect to any Securities by reason
of any order or judgment of any court or governmental authority enjoining,
restraining or otherwise prohibiting such application, then the obligations
under this Indenture and such Securities from which the Company has been





                                      110
<PAGE>   113
discharged or released pursuant to Section 1202 or 1203 shall be revived and
reinstated as though no deposit had occurred pursuant to this Article with
respect to such Securities, until such time as the Trustee or Paying Agent is
permitted to apply all money held in trust pursuant to Section 1205 with
respect to such Securities in accordance with this Article; provided, however,
that if the Company makes any payment of principal of or any premium or
interest on any such Security following such reinstatement of its obligations,
the Company shall be subrogated to the rights (if any) of the Holders of such
Securities to receive such payment from the money so held in trust.

                                        5

           (iv)   that Holders electing to have Registrable Securities exchanged
       pursuant to the Exchange Offer will be required to surrender such
       Registrable Securities, together with the enclosed letters of
       transmittal, to the institution and at the address (located in the
       Borough of Manhattan, The City of New York) specified in the notice prior
       to the close of business on the last Exchange Date; and

           (v)    that Holders will be entitled to withdraw their election, not
       later than the close of business on the last Exchange Date, by sending to
       the institution and at the address (located in the Borough of Manhattan,
       The City of New York) specified in the notice a telegram, telex,
       facsimile transmission or letter setting forth the name of such Holder,
       the number of shares of Registrable Securities delivered for exchange and
       a statement that such Holder is withdrawing his election to have such
       Registrable Securities exchanged.

           As soon as practicable after the last Exchange Date, the Company
       shall:

           (i)    accept for exchange Registrable Securities or portions thereof
       tendered and not validly withdrawn pursuant to the Exchange Offer; and

           (ii)   deliver, or cause to be delivered, to the Trustee for
       cancellation all Registrable Securities or portions thereof so accepted
       for exchange by the Company and issue, and cause the Trustee to promptly
       countersign and register and mail to each Holder, Exchange Securities
       with an aggregate liquidation preference equal to the aggregate
       liquidation preference of the Registrable Securities surrendered by such
       Holder.

The Company shall use its best efforts to complete the Exchange Offer as
provided above and shall comply with the applicable requirements of the 1933
Act, the 1934 Act and other applicable laws and regulations in connection with
the Exchange Offer. The Company shall inform the Placement Agents of the names
and addresses of the Holders to whom the Exchange Offer is made, and the
Placement Agents shall have the right, subject to applicable law, to contact
such Holders and otherwise facilitate the tender of Registrable Securities in
the Exchange Offer.

           (b)    In the event that the Exchange Offer has been completed and in
the opinion of counsel for the Placement Agents a Registration Statement must be
filed and a Prospectus must be delivered by the Placement Agents in connection
with any offering or sale of Registrable Securities held by them that constitute
an unsold allotment, the Company shall use its best efforts to cause to be filed
as soon as practicable after such determination, date or notice of such opinion
of counsel is given to the Company, as the case may be, a Shelf Registration
Statement providing for the sale by the Placement Agents of such Registrable
Securities and to have such Shelf Registration Statement declared effective by
the SEC. The Placement Agents shall sell out their unsold allotments before
making sales of any other Registrable Securities and the Placement Agents shall
notify the Company upon the sale of all of their unsold allotments. The Company
agrees to use its best efforts to keep the Shelf Registration Statement
continuously effective for the period referred to in Rule 144(k) or until all of
the Registrable Securities covered by the Shelf




<PAGE>   6


                                        6

Registration Statement have been sold pursuant to the Shelf Registration
Statement. The Company further agrees to supplement or amend the Shelf
Registration Statement if required by the rules, regulations or instructions
applicable to the registration form used by the Company for such Shelf
Registration Statement or by the 1933 Act or by any other rules and regulations
thereunder for shelf registration or if reasonably requested by a Holder with
respect to information relating to such Holder, and to use its best efforts to
cause any such amendment to become effective and such Shelf Registration
Statement to become usable as soon as thereafter practicable. The Company agrees
to furnish to the Holders of Registrable Securities copies of any such
supplement or amendment promptly after its being used or filed with the SEC.

           (c)    The Company shall pay all Registration Expenses in connection
with the registration pursuant to Section 2(a) or Section 2(b). Each Holder
shall pay all underwriting discounts and commissions and transfer taxes, if any,
relating to the sale or disposition of such Holder's Registrable Securities
pursuant to the Shelf Registration Statement.

           (d)    An Exchange Offer Registration Statement pursuant to Section 
2(a) hereof or a Shelf Registration Statement pursuant to Section 2(b) hereof
will not be deemed to have become effective unless it has been declared
effective by the SEC; provided, however, that if, after it has been declared
effective, the offering of Registrable Securities pursuant to a Shelf
Registration Statement is interfered with by any stop order, injunction or other
order or requirement of the SEC or any other governmental agency or court, such
Registration Statement will be deemed not to have become effective during the
period of such interference until the offering of Registrable Securities
pursuant to such Registration Statement may legally resume. As provided for in
the Indenture, in the event the Exchange Offer is not consummated on or prior to
April 30, 1998, thereafter an additional incremental interest amount will accrue
at an annual rate of 0.5% of the Accreted Value of the Securities as of the most
recent Semi-Annual Accretion Date (as defined in the Indenture), beginning on
May 1, 1998, and, if the Exchange Offer is not consummated on or prior to July
31, 1998, thereafter an additional incremental interest amount will accrue at an
annual rate of 0.5% of the Accreted Value of the Securities as of the most
recent Semi-Annual Accretion Date, beginning on May 1, 1998, until the earlier
of the date upon which (i) the Exchange Offer is consummated, (ii) a Shelf
Registration Statement with respect to all Registrable Securities is declared
effective or (iii) the Securities become freely tradeable without registration
under the 1933 Act; provided that, upon the request of any Holder of the
Securities, the Company will deliver to such Holder certificates evidencing such
Holder's Securities without the legends restricting the transfer thereof.

           (e)    Without limiting the remedies available to the Placement 
Agents and the Holders, the Company acknowledges that any failure by the Company
to comply with its obligations under Section 2(a) and Section 2(b) hereof may
result in material irreparable injury to the Placement Agents or the Holders for
which there is no adequate remedy at law, that it will not be possible to
measure damages for such injuries precisely and that, in the event of any such
failure, the Placement Agents or any Holder may obtain such relief as may be
required to specifically enforce the Company's obligations under Section 2(a)
and Section 2(b) hereof.

           3.     Registration Procedures.

           In connection with the obligations of the Company with respect to the
Registration Statements pursuant to Section 2(a) and Section 2(b) hereof, the
Company shall as expeditiously as possible:

           (a)    prepare and file with the SEC a Registration Statement on the
appropriate form under the 1933 Act, which form (x) shall be selected by the
Company and (y) shall, in the case of a Shelf Registration, be available for the
sale of the Registrable Securities by the selling Holders thereof and (z) shall
comply as to form in all material respects with the requirements of the
applicable form and include all financial statements required by the SEC to be
filed therewith, and use its best efforts to cause such Registration Statement
to become effective and remain effective in accordance with Section 2 hereof;

           (b)    prepare and file with the SEC such amendments and 
post-effective amendments to each Registration Statement as may be necessary to
keep such Registration Statement effective for the applicable period and cause
each Prospectus to be supplemented by any required prospectus supplement and,
as so supplemented, to be filed pursuant to Rule 424 under the 1933 Act; to
keep each Prospectus current during the period described under Section 4(3) and
Rule 174 under the 1933 Act that is applicable to transactions by brokers or
dealers with respect to the Registrable Securities or Exchange Securities;

           (c)    in the case of a Shelf Registration, furnish to each Holder of
Registrable Securities, to counsel for the Placement Agents, to counsel for the
Holders and to each Underwriter of an Underwritten Offering of Registrable
Securities, if any, without charge, as many copies of each Prospectus, including
each preliminary Prospectus, and any amendment or supplement thereto and such
other documents as such Holder or Underwriter may reasonably request, in order
to facilitate the public sale or other disposition of the Registrable
Securities; and the Company consents to the use of such Prospectus and any
amendment or supplement thereto in accordance with applicable law by each of the
selling Holders of Registrable Securities and any such Underwriters in
connection with the offering and sale of the Registrable Securities covered by
and in the manner described in such Prospectus or any amendment or supplement
thereto in accordance with applicable law;

           (d)    use its best efforts to register or qualify the Registrable
Securities under all applicable state securities or "blue sky" laws of such
jurisdictions as any Holder of Registrable Securities covered by a Registration
Statement shall reasonably request in writing by the time the applicable
Registration Statement is declared effective by the SEC, to cooperate with such
Holder in connection with any filings required to be made with the National
Association of Securities Dealers, Inc. and do any and all other acts and things
which may be reasonably necessary or advisable to enable such Holder to
consummate the disposition in each such jurisdiction of such Registrable
Securities owned by such Holder; provided, however, that the Company shall not
be required to (i) qualify as a foreign corporation or as a dealer in securities
in any jurisdiction where




<PAGE>   8


                                        8

it would not otherwise be required to qualify but for this Section 3(d), (ii)
file any general consent to service of process or (iii) subject itself to
taxation in any such jurisdiction if it is not so subject;

           (e)    in the case of a Shelf Registration, notify each Holder of
Registrable Securities, counsel for the Holders and counsel for the Placement
Agents promptly and, if requested by any such Holder or counsel, confirm such
advice in writing (i) when a Registration Statement has become effective and
when any post-effective amendment thereto has been filed and becomes effective,
(ii) of any request by the SEC or any state securities authority for amendments
and supplements to a Registration Statement and Prospectus or for additional
information after the Registration Statement has become effective, (iii) of the
issuance by the SEC or any state securities authority of any stop order
suspending the effectiveness of a Registration Statement or the initiation of
any proceedings for that purpose, (iv) if, between the effective date of a
Registration Statement and the closing of any sale of Registrable Securities
covered thereby, the representations and warranties of the Company contained in
any underwriting agreement, securities sales agreement or other similar
agreement, if any, relating to the offering cease to be true and correct in all
material respects or if the Company receives any notification with respect to
the suspension of the qualification of the Registrable Securities for sale in
any jurisdiction or the initiation of any proceeding for such purpose, (v) of
the happening of any event during the period a Shelf Registration Statement is
effective which makes any statement made in such Shelf Registration Statement or
the related Prospectus untrue in any material respect or which requires the
making of any changes in such Shelf Registration Statement or Prospectus in
order to make the statements therein not misleading and (vi) of any
determination by the Company that a post-effective amendment to a Registration
Statement would be appropriate;

           (f)    make every reasonable effort to obtain the withdrawal of any
order suspending the effectiveness of a Registration Statement at the earliest
possible moment and provide immediate notice to each Holder of the withdrawal of
any such order;

           (g)    in the case of a Shelf Registration, upon request, furnish to
each Holder of Registrable Securities, without charge, at least one conformed
copy of each Registration Statement and any post-effective amendment thereto
(without documents incorporated therein by reference or exhibits thereto, unless
requested);

           (h)    in the case of a Shelf Registration, cooperate with the 
selling Holders of Registrable Securities to facilitate the timely preparation
and delivery of certificates representing Registrable Securities to be sold and
not bearing any restrictive legends and enable such Registrable Securities to
be in such denominations (consistent with the provisions of the Indenture) and
registered in such names as the selling Holders may reasonably request at least
two business days prior to the closing of any sale of Registrable Securities;

           (i)    in the case of a Shelf Registration, upon the occurrence of 
any event contemplated by Section 3(e)(v) hereof, use its best efforts to
prepare and file with the SEC a supplement or post-effective amendment to a
Registration Statement or the related Prospectus or any document incorporated
therein by reference or file any other required document so that, as




<PAGE>   9


                                        9

thereafter delivered to the purchasers of the Registrable Securities, such
Prospectus will not contain any untrue statement of a material fact or omit to
state a material fact necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading. The Company agrees to
notify the Holders to suspend use of the Prospectus as promptly as practicable
after the occurrence of such an event, and the Holders hereby agree to suspend
use of the Prospectus until the Company has amended or supplemented the
Prospectus to correct such misstatement or omission;

           (j)    a reasonable time prior to the filing of any Registration
Statement, any Prospectus, any amendment to a Registration Statement or
amendment or supplement to a Prospectus or any document which is to be
incorporated by reference into a Registration Statement (other than filings
pursuant to the 1934 Act) or a Prospectus after the initial filing of a
Registration Statement, provide copies of such document to the Placement Agents
and their counsel (and, in the case of a Shelf Registration Statement, the
Holders and their counsel) and make such of the representatives of the Company
as shall be reasonably requested by the Placement Agents or their counsel (and,
in the case of a Shelf Registration Statement, the Holders or their counsel)
available for discussion of such document, and shall not at any time file or
make any amendment to the Registration Statement, any Prospectus or any
amendment of or supplement to a Registration Statement or a Prospectus or any
document which is to be incorporated by reference into a Registration Statement
(other than filings pursuant to the 1934 Act) or a Prospectus, of which the
Placement Agents and their counsel (and, in the case of a Shelf Registration
Statement, the Holders and their counsel) shall not have previously been advised
and furnished a copy or to which the Placement Agents or their counsel (and, in
the case of a Shelf Registration Statement, the Holders or their counsel) shall
object;

           (k)    obtain a CUSIP number and a CINS number for all Exchange
Securities or Registrable Securities, as the case may be, not later than the
effective date of a Registration Statement;

           (l)    in the case of a Shelf Registration, make available for
inspection by a representative of the Holders of the Registrable Securities, any
Underwriter participating in any disposition pursuant to such Shelf Registration
Statement, and attorneys and accountants designated by the Holders, at
reasonable times and in a reasonable manner, all financial and other records,
pertinent documents and properties of the Company, and cause the respective
officers, directors and employees of the Company to supply all information
reasonably requested by any such representative, Underwriter, attorney or
accountant in connection with a Shelf Registration Statement;

           (m)    in the case of a Shelf Registration, use its best efforts to
cause all Registrable Securities to be listed on any securities exchange or any
automated quotation system on which similar securities issued by the Company are
then listed if requested by the Majority Holders, to the extent such Registrable
Securities satisfy applicable listing requirements;



<PAGE>   10


                                       10

           (n)    use its best efforts to cause the Exchange Securities or
Registrable Securities, as the case may be, to be rated by two nationally
recognized statistical rating organizations (as such term is defined in Rule
436(g)(2) under the 1933 Act);

           (o)    if reasonably requested by any Holder of Registrable 
Securities covered by a Registration Statement, (i) promptly incorporate in a
Prospectus supplement or post-effective amendment such information with respect
to such Holder as such Holder reasonably requests to be included therein and
(ii) make all required filings of such Prospectus supplement or such
post-effective amendment as soon as the Company has received notification of
the matters to be incorporated in such filing; and

           (p)    in the case of a Shelf Registration, enter into such customary
agreements and take all such other actions in connection therewith (including
those requested by the Holders of a majority of the Registrable Securities being
sold) in order to expedite or facilitate the disposition of such Registrable
Securities including, but not limited to, an Underwritten Offering and in such
connection, (i) to the extent possible, make such representations and warranties
to the Holders and any Underwriters of such Registrable Securities with respect
to the business of the Company and its subsidiaries, the Registration Statement,
Prospectus and documents incorporated by reference or deemed incorporated by
reference, if any, in each case, in form, substance and scope as are customarily
made by issuers to underwriters in underwritten offerings and confirm the same
if and when requested, (ii) obtain opinions of counsel to the Company (which
counsel and opinions, in form, scope and substance, shall be reasonably
satisfactory to the Holders and such Underwriters and their respective counsel)
addressed to each selling Holder and Underwriter of Registrable Securities,
covering the matters customarily covered in opinions requested in underwritten
offerings, (iii) obtain "cold comfort" letters from the independent certified
public accountants of the Company (and, if necessary, any other certified public
accountant of any subsidiary of the Company, or of any business acquired by the
Company for which financial statements and financial data are or are required to
be included in the Registration Statement) addressed to each selling Holder and
Underwriter of Registrable Securities, such letters to be in customary form and
covering matters of the type customarily covered in "cold comfort" letters in
connection with underwritten offerings, and (iv) deliver such documents and
certificates as may be reasonably requested by the Holders of a majority of the
Registrable Securities being sold or the Underwriters, and which are customarily
delivered in underwritten offerings, to evidence the continued validity of the
representations and warranties of the Company made pursuant to clause (i) above
and to evidence compliance with any customary conditions contained in an
underwriting agreement.

           In the case of a Shelf Registration Statement, the Company may
require each Holder of Registrable Securities to furnish to the Company such
information regarding the Holder and the proposed distribution by such Holder of
such Registrable Securities as the Company may from time to time reasonably
request in writing.

           In the case of a Shelf Registration Statement, each Holder agrees
that, upon receipt of any notice from the Company of the happening of any event
of the kind described in






<PAGE>   11


                                       11

Section 3(e)(v) hereof, such Holder will forthwith discontinue disposition of
Registrable Securities pursuant to a Registration Statement until such Holder's
receipt of the copies of the supplemented or amended Prospectus contemplated by
Section 3(i) hereof, and, if so directed by the Company, such Holder will
deliver to the Company (at its expense) all copies in its possession, other than
permanent file copies then in such Holder's possession, of the Prospectus
covering such Registrable Securities current at the time of receipt of such
notice. The Company shall not suspend the disposition of Registrable Securities
pursuant to a Shelf Registration Statement for more than an aggregate of 120
days during any 365 day period. If the Company shall suspend the disposition of
Registrable Securities pursuant to a Shelf Registration Statement for more than
an aggregate of 60 days during any 365 day period, then the Company shall pay
each Holder of Registrable Securities that are registered pursuant to the Shelf
Registration Statement and have not been sold pursuant thereto an illiquidity
fee in an amount equal to one half of one percent per annum (calculated at an
annual rate for the actual number of days of suspension in excess of 60 days in
such 365 day period) of the Accreted Value of such Registrable Securities held
by such Holder as of the most recent Semi-Annual Accretion Date.

           The Holders of Registrable Securities covered by a Shelf Registration
Statement who desire to do so may sell such Registrable Securities in an
Underwritten Offering. In any such Underwritten Offering, the investment banker
or investment bankers and manager or managers (the "Underwriters") that will
administer the offering will be selected by the Majority Holders of the
Registrable Securities included in such offering.

           4.     Participation of Broker-Dealers in Exchange Offer.

           (a)    The Staff of the SEC has taken the position that any
broker-dealer that receives Exchange Securities for its own account in the
Exchange Offer in exchange for Securities that were acquired by such
broker-dealer as a result of market-making or other trading activities (a
"Participating Broker-Dealer"), may be deemed to be an "underwriter" within the
meaning of the 1933 Act and must deliver a prospectus meeting the requirements
of the 1933 Act in connection with any resale of such Exchange Securities.

           The Company understands that it is the Staff's position that if the
Prospectus contained in the Exchange Offer Registration Statement includes a
plan of distribution containing a statement to the above effect and the means by
which Participating Broker-Dealers may resell the Exchange Securities, without
naming the Participating Broker-Dealers or specifying the amount of Exchange
Securities owned by them, such Prospectus may be delivered by Participating
Broker-Dealers to satisfy their prospectus delivery obligation under the 1933
Act in connection with resales of Exchange Securities for their own accounts, so
long as the Prospectus otherwise meets the requirements of the 1933 Act.

           (b)    In light of the above, notwithstanding the other provisions of
this Agreement, the Company agrees that the provisions of this Agreement as they
relate to a Shelf Registration shall also apply to an Exchange Offer
Registration to the extent, and with such reasonable modifications thereto as
may be, reasonably requested by the Placement Agents or by






<PAGE>   12


                                       12

one or more Participating Broker-Dealers, in each case as provided in clause
(ii) below, in order to expedite or facilitate the disposition of any Exchange
Securities by Participating Broker-Dealers consistent with the positions of the
Staff recited in Section 4(a) above; provided that:

           (i)    the Company shall not be required to amend or supplement the
       Prospectus contained in the Exchange Offer Registration Statement, as
       would otherwise be contemplated by Section 3(i) of this Agreement, for a
       period exceeding 90 days after the last Exchange Date (as such period may
       be extended pursuant to the penultimate paragraph of Section 3 of this
       Agreement) and Participating Broker-Dealers shall not be authorized by
       the Company to deliver and shall not deliver such Prospectus after such
       period in connection with the resales contemplated by this Section 4;

           (ii)   the application of the Shelf Registration procedures set forth
       in Section 3 of this Agreement to an Exchange Offer Registration, to the
       extent not required by the positions of the Staff of the SEC or the 1933
       Act and the rules and regulations thereunder, will be in conformity with
       the reasonable request to the Company by the Placement Agents or with the
       reasonable request in writing to the Company by one or more
       broker-dealers who certify to the Placement Agents and the Company in
       writing that they anticipate that they will be Participating
       Broker-Dealers; and provided further that, in connection with such
       application of the Shelf Registration procedures set forth in Section 3
       of this Agreement to an Exchange Offer Registration, the Company shall be
       obligated (x) to deal only with one entity representing the Participating
       Broker-Dealers, which shall be MS unless it elects not to act as such
       representative and (y) to cause to be delivered only one, if any, "cold
       comfort" letter with respect to the Prospectus in the form existing on
       the last Exchange Date and with respect to each subsequent amendment or
       supplement, if any, effected during the period specified in clause (i)
       above; and

           (iii)  on a weekly basis, the representative of the Participating
       Broker-Dealers will confirm with the Company that the Shelf Registration
       Statement is available.

           (c)    The Placement Agents shall have no liability to the Company or
any Holder with respect to any request that it may make pursuant to Section 4(b)
above.

           5.     Indemnification and Contribution.

           (a)    The Company agrees to indemnify and hold harmless the 
Placement Agents, each Holder, each Participating Broker-Dealer, each
Underwriter and each Person, if any, who controls any Holder or Underwriter
within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act
as follows:

           (i)    against any and all loss, liability, claim, damage and expense
       whatsoever, as incurred, arising out of any untrue statement or alleged
       untrue statement of a material fact contained in any Registration
       Statement (or any amendment or supplement thereto)




<PAGE>   13


                                       13

       pursuant to which Exchange Securities or Registrable Securities were
       registered under the 1933 Act, including all documents incorporated
       therein by reference, or the omission or alleged omission therefrom of a
       material fact necessary to make the statements therein not misleading, or
       arising out of any untrue statement or alleged untrue statement of a
       material fact contained in any Prospectus (or any amendment or supplement
       thereto) or the omission or alleged omission therefrom of a material fact
       necessary in order to make the statements therein, in the light of the
       circumstances under which they were made, not misleading;

           (ii)   against any and all loss, liability, claim, damage and expense
       whatsoever, as incurred, to the extent of the aggregate amount paid in
       settlement of any litigation, or any investigation or proceeding by any
       governmental agency or body, commenced or threatened, or of any claim
       whatsoever based upon any such untrue statement or omission, or any such
       alleged untrue statement or omission; provided that (subject to Section
       5(d) below) any such settlement is effected with the written consent of
       the Company; and

           (iii)  against any and all expense whatsoever, as incurred (including
       the fees and disbursements of counsel chosen by any indemnified party),
       reasonably incurred in investigating, preparing or defending against any
       litigation, or any investigation or proceeding by any governmental agency
       or body, commenced or threatened, or any claim whatsoever based upon any
       such untrue statement or omission, or any such alleged untrue statement
       or omission, to the extent that any such expense is not paid under
       subparagraph (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company by the
Placement Agents, such Holder or Underwriter expressly for use in a Registration
Statement (or any amendment thereto) or any Prospectus (or any amendment or
supplement thereto); provided further, however, that the foregoing indemnity
agreement with respect to any prospectus shall not inure to the benefit of any
Placement Agent or Holder from whom the person asserting any such losses,
claims, damages or liabilities purchased Securities, or any person controlling
such Placement Agent or Holder, if a copy of the final prospectus (as then
amended or supplemented if the Company shall have furnished any amendments or
supplements thereto) was not sent or given by or on behalf of such Placement
Agent or Holder to such person, if required by law so to have been delivered, at
or prior to the written confirmation of the sale of the Securities to such
person, and if the final prospectus (as so amended or supplemented) would have
cured the defect giving rise to such losses, claims, damages or liabilities,
unless such failure is the result of noncompliance by the Company with Section
3(c) hereof.

           (b)    Each Holder severally, but not jointly, agrees to indemnify 
and hold harmless the Company and the other selling Holders, and each of their
respective directors and officers, and each Person, if any, who controls the
Company or any other selling Holder within the meaning of Section 15 of the
1933 Act or Section 20 of the 1934 Act, against any and all loss,






<PAGE>   14


                                       14

liability, claim, damage and expense to the same extent as described in Section
5(a) hereof, as incurred, but only with respect to untrue statements or
omissions, or alleged untrue statements or omissions, made in the Shelf
Registration Statement (or any amendment thereto) or any Prospectus included
therein (or any amendment or supplement thereto) in reliance upon and in
conformity with written information furnished to the Company by such Holder
expressly for use in the Shelf Registration Statement (or any amendment thereto)
or such Prospectus (or any amendment or supplement thereto); provided, however,
that no such Holder shall be liable for any claims hereunder in excess of the
amount of net proceeds received by such Holder from the sale of Registrable
Securities pursuant to such Shelf Registration Statement.

           (c)    Each indemnified party shall give notice as promptly as
reasonably practicable to each indemnifying party of any action commenced
against it in respect of which indemnity may be sought hereunder, but failure to
so notify an indemnifying party shall not relieve such indemnifying party from
any liability hereunder to the extent it is not materially prejudiced as a
result thereof and in any event shall not relieve it from any liability which it
may have otherwise than on account of this indemnity agreement. Upon request of
the indemnified party, the indemnifying party shall retain counsel reasonably
satisfactory to the indemnified party to represent the indemnified party. In any
such proceeding, any indemnified party shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of
such indemnified party unless (i) the indemnifying party and the indemnified
party shall have mutually agreed to the retention of such counsel or (ii) the
named parties to any such proceeding (including any impleaded parties) include
both the indemnifying party and the indemnified party and representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them, in which case the indemnifying party shall pay
the expenses of the separate counsel of such indemnified party. In the case of
parties indemnified pursuant to Section 5(a) above, such counsel to the
indemnified parties shall be selected by MS, and, in the case of parties
indemnified pursuant to Section 5(b) above, such counsel to the indemnified
parties shall be selected by the Company. In no event shall the indemnifying
party or parties be liable for the fees and expenses of more than one counsel
(in addition to any local counsel) separate from their own counsel for all
indemnified parties in connection with any one action or separate but similar or
related actions in the same jurisdiction arising out of the same general
allegations or circumstances. No indemnifying party shall, without the prior
written consent of the indemnified parties, settle or compromise or consent to
the entry of any judgment with respect to any litigation, or any investigation
or proceeding by any governmental agency or body, commenced or threatened, or
any claim whatsoever in respect of which indemnification or contribution could
be sought under this Section 5 (whether or not the indemnified parties are
actual or potential parties thereto), unless such settlement, compromise or
consent (i) includes an unconditional release of each indemnified party from all
liability arising out of such litigation, investigation, proceeding or claim and
(ii) does not include a statement as to or an admission of fault, culpability or
a failure to act by or on behalf of any indemnified party; provided, that such
unconditional release may be subject to a parallel release of a claimant or
plaintiff by such indemnified party from all liability in respect of claims or
counterclaims asserted by such indemnified party arising out of the same subject
matter.






<PAGE>   15


                                       15

           (d)    If at any time an indemnified party shall have requested an
indemnifying party to reimburse the indemnified party for fees and expenses of
counsel, such indemnifying party agrees that it shall be liable for any
settlement of the nature contemplated by Section 5(a)(ii) effected without its
written consent if (i) such settlement is entered into more than 45 days after
receipt by such indemnifying party of the aforesaid request, (ii) such
indemnifying party shall have received notice of the terms of such settlement at
least 30 days prior to such settlement being entered into and (iii) such
indemnifying party shall not have reimbursed such indemnified party in
accordance with such request prior to the date of such settlement.

           (e)    If the indemnification provided for in this Section 5 is for
any reason unavailable to or insufficient to hold harmless an indemnified party
in respect of any losses, liabilities, claims, damages or expenses referred to
therein, then each indemnifying party shall contribute to the aggregate amount
of such losses, liabilities, claims, damages and expenses incurred by such
indemnified party, as incurred, in such proportion as is appropriate to reflect
the relative fault of the Company on the one hand and the Holders and the
Placement Agents on another hand in connection with the statements or omissions
which resulted in such losses, liabilities, claims, damages or expenses, as
well as any other relevant equitable considerations.

           The relative fault of the Company on the one hand and the Holders and
the Placement Agents on the other hand shall be determined by reference to,
among other things, whether any such untrue or alleged untrue statement of a
material fact or omission or alleged omission to state a material fact relates
to information supplied by the Company, the Holders or the Placement Agents and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission.

           The Company, the Holders and the Placement Agents agree that it would
not be just and equitable if contribution pursuant to this Section 5 were
determined by pro rata allocation (even if the Placement Agents were treated as
one entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to above in this Section
5. The aggregate amount of losses, liabilities, claims, damages and expenses
incurred by an indemnified party and referred to above in this Section 5 shall
be deemed to include any legal or other expenses reasonably incurred by such
indemnified party in investigating, preparing or defending against any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever based upon any such
untrue or alleged untrue statement or omission or alleged omission.

           Notwithstanding the provisions of this Section 5, no Placement Agent
shall be required to contribute any amount in excess of the amount by which the
total price at which the Securities sold by it were offered exceeds the amount
of any damages which such Placement Agent has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission.

                                       16

           No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the 1933 Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation.

           For purposes of this Section 5, each person, if any, who controls a
Placement Agent or Holder within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act shall have the same rights to contribution as such
Placement Agent or Holder, and each director of the Company, and each person, if
any, who controls the Company within the meaning of Section 15 of the 1933 Act
or Section 20 of the 1934 Act shall have the same rights to contribution as the
Company. The Placement Agents' respective obligations to contribute pursuant to
this Section 5 are several in proportion to the principal amount of Securities
set forth opposite their respective names in Schedule I(a) to the Purchase
Agreement and not joint.

           6.     Miscellaneous.

           (a)    No Inconsistent Agreements. The Company has not entered into,
and on or after the date of this Agreement will not enter into, any agreement
which is inconsistent with the rights granted to the Holders of Registrable
Securities in this Agreement or otherwise conflicts with the provisions hereof.
The rights granted to the Holders hereunder do not in any way conflict with and
are not inconsistent with the rights granted to the holders of the Company's
other issued and outstanding securities under any such agreements.

           (b)    Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given unless the Company has obtained the written consent of Holders
of at least a majority in aggregate principal amount of the outstanding
Registrable Securities affected by such amendment, modification, supplement,
waiver or consent; provided, however, that no amendment, modification,
supplement, waiver or consents to any departure from the provisions of Section 5
hereof shall be effective as against any Holder of Registrable Securities unless
consented to in writing by such Holder.

           (c)    Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, registered
first-class mail, telex, telecopier, or any courier guaranteeing overnight
delivery (i) if to a Holder, at the most current address given by such Holder to
the Company by means of a notice given in accordance with the provisions of this
Section 6(c), which address initially is, with respect to the Placement Agents,
the address set forth in the Purchase Agreement; and (ii) if to the Company,
initially at the Company's address set forth in the Purchase Agreement and
thereafter at such other address, notice of which is given in accordance with
the provisions of this Section 6(c).

           All such notices and communications shall be deemed to have been duly
given: at the time delivered by hand, if personally delivered; two business days
after being deposited in the mail, postage prepaid, if mailed; when answered
back, if telexed; when receipt is acknowledged, if






<PAGE>   17


                                       17

telecopied; and on the next business day if timely delivered to an air courier
guaranteeing overnight delivery.

           Copies of all such notices, demands, or other communications shall be
concurrently delivered by the person giving the same to the Trustee under the
Indenture, at the address specified in such Indenture.

           (d)    Successors and Assigns. This Agreement shall inure to the 
benefit of and be binding upon the successors, assigns and transferees of each
of the parties, including, without limitation and without the need for an
express assignment, subsequent Holders; provided that nothing herein shall be
deemed to permit any assignment, transfer or other disposition of Registrable
Securities in violation of the terms of the Purchase Agreement. If any
transferee of any Holder shall acquire Registrable Securities, in any manner,
whether by operation of law or otherwise, such Registrable Securities shall be
held subject to all of the terms of this Agreement, and by taking and holding
much Registrable Securities such person shall be conclusively deemed to have
agreed to be bound by and to perform all of the terms and provisions of this
Agreement and such person shall be entitled to receive the benefits hereof. The
Placement Agents (in their capacity as Placement Agents) shall have no
liability or obligation to the Company with respect to any failure by a Holder
to comply with, or any breach by any Holder of, any of the obligations of such
Holder under this Agreement.

           (e)    Purchases and Sales of Securities. The Company shall not, and
shall use its best efforts to cause its affiliates (as defined in Rule 405 under
the 1933 Act) not to, purchase and then resell or otherwise transfer any
Securities.

           (f)    Third Party Beneficiary. The Holders shall be third party
beneficiaries to the agreements made hereunder between the Company, on the one
hand, and the Placement Agents, on the other hand, and each Holder shall have
the right to enforce such agreements directly to the extent it deems such
enforcement necessary or advisable to protect its rights or the rights of
Holders hereunder.

           (g)    Counterparts. This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

           (h)    Headings. The headings in this Agreement are for convenience
of reference only and shall not limit or otherwise affect the meaning hereof.

           (i)    Governing Law. This Agreement shall be governed by and 
construed in accordance with the laws of the State of New York.

           (j)    Severability. In the event that any one or more of the 
provisions contained herein, or the application thereof in any circumstance, is
held invalid, illegal or unenforceable, the






<PAGE>   18


                                       18

validity, legality and enforceability of any such provision in every other
respect and of the remaining provisions contained herein shall not be affected
or impaired thereby.

Ladies and Gentlemen:

        We are acting as counsel to Nextel Communications, Inc. (the
"Company"), a corporation organized under the laws of the State of Delaware, in
connection with the offer to exchange (the "Exchange Offer") one $1,000
principal amount at maturity of the Company's 9.75% Senior Serial Redeemable
Discount Notes due October 31, 2007 (the Exchange Senior Notes") for each $1,000
principal amount at maturity of the Company's outstanding 9.75% Senior Serial
Redeemable Discount Notes due October 31, 2007 (the "Private Notes"), and in
connection with the preparation of the prospectus (the "Prospectus") contained
in the registration statement on Form S-4 (the "Registration Statement") (No.
333-41097) filed with the Securities and Exchange Commission by the Company for
the purpose of registering the Exchange Senior Notes under the Securities Act of
1933, as amended (the "Act").  The Private Notes have been, and the Exchange
Senior Notes will be, issued pursuant to an Indenture, dated as of October 22,
1997 (the "Indenture"), among the Company and Harris Trust and Savings Bank, as
Trustee. Unless otherwise defined herein, terms defined in the Prospectus are
used herein as defined therein.

        We have examined originals or copies, certified or otherwise identified
to our satisfaction, of such corporate records, agreements, documents, and
other instruments and such certificates or comparable documents of public
officials and representatives of the Company and have made such other and
further investigations as we have deemed relevant and necessary as a basis for
the opinion hereinafter set forth.  In such examination, we have assumed the
genuineness of all signatures, the legal capacity of natural persons, the
authenticity of all documents submitted to us as originals, the conformity to
original documents of all documents submitted to us as certified or photostatic
copies, and the authenticity of the originals of such latter documents.

        Based on the foregoing, and subject to the qualifications and
limitations stated herein, we are of the opinion that, assuming the due
authorization, execution, and delivery by the Trustee of the Indenture, when
the Exchange Senior Notes, substantially in the form as set forth

in an exhibit to the Indenture filed as Exhibit 4.54 to the Registration
Statement, have been duly executed by the Company and authenticated by the
Trustee in accordance with the Indenture and duly delivered in exchange for the
Private Notes in accordance with the Exchange Offer in the manner described in
the Registration Statement, the Exchange Senior Notes will constitute valid and
legally binding obligations of the Company enforceable in accordance with their
terms, except to the extent enforceability may be limited by bankruptcy,
insolvency, fraudulent conveyance, reorganization, moratorium and other similar
laws relating to or affecting creditors' rights generally and general equitable
principles (whether considered in a proceeding in equity or at law).

        We hereby consent to the use of our name under the caption "Legal
Matters" in the Prospectus forming part of the Registration Statement and to
the filing of this opinion as Exhibit 5 to the Registration Statement.

                                        Very truly yours,

         Re:  Exchange Offer for 9.75% Senior Serial Redeembable Discount 
              Notes due 2007

Dear Sirs:

        We have acted as counsel to Nextel Communications, Inc. in connection
with the Registration Statement on Form S-4, to which this opinion appears as
Exhibit 8, which includes the Prospectus of the Company relating to the
Exchange Offer (as such term is defined in the Prospectus).  Unless otherwise
indicated, any capitalized terms used herein shall have the same meanings that
such terms have in the Prospectus.

        On the basis of the foregoing and upon consideration of applicable law,
we are of the opinion that, subject to the qualifications stated therein, the
discussion of the Unites States federal income tax matters set forth under the
caption "Certain United States Federal Income Tax Considerations" in the
Prospectus contained in the Registration Statement summarizes the principal
United States federal income tax consequences relevant to the Exchange Offer
and to purchase, ownership and disposition of the Exchange Senior Notes.

        We hereby consent to the filing with the Securities and Exchange
Commission of this opinion as an exhibit to the Registration Statement and to
the reference to this firm in the Prospectus constituting part of the
Registration Statement.

                                        Very truly yours,

Ladies and Gentlemen:
 
     Subject to the terms and conditions of the Exchange Offer, the undersigned
hereby tenders to the Company the principal amount of Private Notes indicated
above. Subject to and effective upon the acceptance for exchange of the
principal amount of Private Notes tendered in accordance with this Letter of
Transmittal, the undersigned sells, assigns, and transfers to, or upon the order
of, the Company all right, title and interest in and to the Private Notes
tendered hereby. The undersigned hereby irrevocably constitutes and appoints the
Exchange Agent as its agent and attorney-in-fact (with full knowledge that the
Exchange Agent also acts as the agent of the Company) with respect to the
tendered Private Notes with full power of substitution to (i) deliver
certificates for such Private Notes, or transfer ownership of such Private Notes
on the account books maintained by DTC, to the Company and deliver all
accompanying evidences of transfer and authenticity to, or upon the order of,
the Company, and (ii) present such Private Notes for transfer on the books of
the Company and receive all benefits and otherwise exercise all rights of
beneficial ownership of such Private Notes, all in accordance with the terms of
the Exchange Offer. The power of attorney granted in this paragraph shall be
deemed to be irrevocable and coupled with an interest.
 
     The undersigned hereby represents and warrants that he or she has full
power and authority to tender, sell, assign, and transfer the Private Notes
tendered hereby and that the Company will acquire good and unencumbered title
thereto, free and clear of all liens, restrictions, charges, and encumbrances
and not subject to any adverse claim, when the same are acquired by the Company.
The undersigned hereby further represents that (i) any Exchange Senior Notes
acquired in exchange for Private Notes tendered hereby will have been acquired
in the ordinary course of business of the person receiving such Exchange Senior
Notes, whether or not such person is the undersigned, (ii) neither the
undersigned nor any such other person is engaging in or intends to engage in a
distribution of the Exchange Senior Notes, (iii) neither the Holder nor any such
other person has an arrangement or understanding with any person to participate
in the distribution of such Exchange Senior Notes, and (iv) neither the Holder
nor any such other person is an "affiliate" (as defined in Rule 405 under the
Securities Act) of the Company.
 
     The undersigned also acknowledges that this Exchange Offer is being made in
reliance upon interpretations contained in letters issued to third parties by
the staff of the Securities and Exchange Commission (the "SEC") that the
Exchange Senior Notes issued in exchange for the Private Notes pursuant to the
Exchange Offer may be offered for resale, resold, and otherwise transferred by
Holders thereof (other than any such Holder that is an "affiliate" of the
Company within the meaning of Rule 405 under the Securities Act), without
compliance with the registration and prospectus delivery provisions of the
Securities Act, provided that such Exchange Senior Notes are acquired in the
ordinary course of such Holder's business and such Holder is not engaging in and
does not intend to engage in a distribution of the Exchange Senior Notes and has
no arrangement or understanding with any person to participate in a distribution
of such Exchange Senior Notes. If the undersigned is not a broker-dealer, the
undersigned represents that it is not engaged in, and does not intend to engage
in, a distribution of Exchange Senior Notes. If the undersigned is a
broker-dealer that will receive Exchange Senior Notes for its own account in
exchange for Private Notes that were acquired as a result of market-making
activities or other trading activities (a "Participating Broker-Dealer"), it
acknowledges that it will deliver a prospectus in connection with any resale of
such Exchange Senior Notes; however, by so acknowledging and by delivering a
prospectus, the undersigned will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act. If the undersigned is a
Participating Broker-Dealer, it acknowledges that during the 90-day period
following the Expiration Date (or such longer applicable period if use of the
Prospectus has been suspended by the Company) it will contact counsel to the
Placement Agents at (212) 848-7961 on a weekly basis to confirm the availability
of the Prospectus for delivery in connection with such resales.
 
     The undersigned will, upon request, execute and deliver any additional
documents deemed by the Exchange Agent or the Company to be necessary or
desirable to complete the assignment, transfer, and purchase of the Private
Notes tendered hereby.
 
     For purposes of the Exchange Offer, the Company shall be deemed to have
accepted validly tendered Private Notes when, as and if the Company has given
oral or written notice thereof to the Exchange Agent.

     If any tendered Private Notes are not accepted for exchange pursuant to the
Exchange Offer for any reason, certificates for any such unaccepted Private
Notes will be returned, without expense, to the undersigned at the address shown
below or at a different address as may be indicated herein under "Special
Delivery Instructions" or, in the case of Private Notes tendered by book-entry
transfer, such unaccepted Private Notes will be credited to an account at DTC,
as promptly as practicable after the Expiration Date.
 
     All authority conferred or agreed to be conferred by this Letter of
Transmittal shall survive the death, incapacity or dissolution of the
undersigned, and every obligation of the undersigned under this Letter of
Transmittal shall be binding upon the undersigned's heirs, personal
representatives, successors, and assigns.
 
     The undersigned understands that tenders of Private Notes pursuant to the
procedures described under the caption "The Exchange Offer -- Procedures for
Tendering" in the Prospectus and in the instructions hereto will constitute a
binding agreement between the undersigned and the Company upon the terms and
subject to the conditions of the Exchange Offer.
 
     Unless otherwise indicated under "Special Issuance Instructions," please
issue the certificates representing the Exchange Senior Notes issued in exchange
for the Private Notes accepted for exchange and return any Private Notes not
tendered or not exchanged in the name(s) of the undersigned. Similarly, unless
otherwise indicated under "Special Delivery Instructions," please send the
certificates representing the Exchange Senior Notes issued in exchange for the
Private Notes accepted for exchange and any certificates for Private Notes not
tendered or not exchanged (and accompanying documents, as appropriate) to the
undersigned at the address shown below the undersigned's signature(s). In the
event that both "Special Payment Instructions" and "Special Delivery
Instructions" are completed, please issue the certificates representing the
Exchange Senior Notes issued in exchange for the Private Notes accepted for
exchange in the name(s) of, and return any Private Notes not tendered or not
exchanged and send said certificates to, the person(s) so indicated. The
undersigned recognizes that the Company has no obligation pursuant to the
"Special Payment Instructions" and "Special Delivery Instructions" to transfer
any Private Notes from the name of the registered Holder(s) thereof if the
Company does not accept for exchange any of the Private Notes so tendered.
 
     Holders of Private Notes who wish to tender their Private Notes and (i)
whose Private Notes are not immediately available, or (ii) who cannot deliver
their Private Notes, this Letter of Transmittal or any other documents required
hereby to the Exchange Agent prior to the Expiration Date (or who cannot comply
with the book-entry transfer procedures on a timely basis), may tender their
Private Notes according to the guaranteed delivery procedures set forth in the
Prospectus under the caption "The Exchange Offer -- Guaranteed Delivery
Procedures." See Instruction 1 regarding the completion of this Letter of
Transmittal.

         FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER
 
     1. DELIVERY OF THIS LETTER OF TRANSMITTAL AND PRIVATE NOTES.  The tendered
Private Notes or any confirmation of a book-entry transfer (a "Book-Entry
Confirmation"), as well as a properly completed and duly executed copy of this
Letter of Transmittal or facsimile hereof and any other documents required by
this Letter of Transmittal must be received by the Exchange Agent at its address
set forth herein prior to 5:00 p.m., New York City time, on the Expiration Date.
THE METHOD OF DELIVERY OF THE TENDERED PRIVATE NOTES, THIS LETTER OF TRANSMITTAL
AND ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND
RISK OF THE HOLDER AND, EXCEPT AS OTHERWISE PROVIDED BELOW, THE DELIVERY WILL BE
DEEMED MADE ONLY WHEN ACTUALLY RECEIVED OR CONFIRMED BY THE EXCHANGE AGENT.
INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT THE HOLDER USE AN OVERNIGHT
OR HAND DELIVERY SERVICE. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO
ASSURE DELIVERY TO THE EXCHANGE AGENT BEFORE THE EXPIRATION DATE. NO LETTER OF
TRANSMITTAL OR PRIVATE NOTES SHOULD BE SENT TO THE COMPANY. HOLDERS MAY REQUEST
THEIR RESPECTIVE BROKERS, DEALERS, COMMERCIAL BANKS, TRUST COMPANIES, OR
NOMINEES TO EFFECT THE ABOVE TRANSACTIONS FOR SUCH HOLDERS.
 
     Holders who wish to tender their Private Notes and (i) whose Private Notes
are not immediately available, or (ii) who cannot deliver their Private Notes,
this Letter of Transmittal, or any other documents required hereby to the
Exchange Agent prior to the Expiration Date, or (iii) who are unable to complete
the procedure for book-entry transfer on a timely basis, must tender their
Private Notes according to the guaranteed delivery procedures set forth in the
Prospectus. Pursuant to such procedure: (i) such tender must be made by or
through an Eligible Institution; (ii) prior to the Expiration Date, the Exchange
Agent must have received from the Eligible Institution a properly completed and
duly executed Notice of Guaranteed Delivery (by facsimile transmission, mail or
hand delivery) setting forth the name and address of the Holder of the Private
Notes, the certificate number or numbers of such Private Notes and the aggregate
principal amount of Private Notes tendered, stating that the tender is being
made thereby and guaranteeing that, within three New York Stock Exchange trading
days after the Expiration Date, this Letter of Transmittal (or facsimile hereof)
together with the certificate(s) representing the Private Notes or a Book-Entry
Confirmation and any other required documents will be deposited by the Eligible
Institution (as hereinafter defined) with the Exchange Agent; and (iii) such
properly completed and executed Letter of Transmittal (or facsimile thereof), as
well as all other documents required by this Letter of Transmittal and the
certificate(s) representing all tendered Private Notes (or a Book-Entry
Confirmation) in proper form for transfer, must be received by the Exchange
Agent within three New York Stock Exchange trading days after the Expiration
Date, all as provided in the Prospectus under the caption "The Exchange
Offer -- Guaranteed Delivery Procedures." Any Holder of Private Notes who wishes
to tender his Private Notes pursuant to the guaranteed delivery procedures
described above must ensure that the Exchange Agent receives the Notice of
Guaranteed Delivery prior to 5:00 p.m., New York City time, on the Expiration
Date. Upon request of the Exchange Agent, a Notice of Guaranteed Delivery will
be sent to Holders who wish to tender their Private Notes according to the
guaranteed delivery procedures set forth above.
 
     All questions as to the validity, form, eligibility (including time of
receipt), acceptance of tendered Private Notes, and withdrawal of tendered
Private Notes will be determined by the Company in its sole discretion, which
determination will be final and binding. The Company reserves the absolute right
to reject any and all Private Notes not properly tendered or any Private Notes
the Company's acceptance of which would, in the opinion of counsel for the
Company, be unlawful. The Company also reserves the right to waive any
irregularities or conditions of tender as to particular Private Notes. The
Company's interpretation of the terms and conditions of the Exchange Offer,
including the instructions in this Letter of Transmittal and those set forth in
the Prospectus under the caption "The Exchange Offer -- Conditions," shall be
final and binding on all parties. Unless waived, any defects or irregularities
in connection with tenders of Private Notes must be cured within such time as
the Company shall determine. Neither the Company, the Exchange Agent nor any
other person shall be under any duty to give notification of defects or
irregularities with respect to tenders of Private Notes, nor shall any of them
incur any liability for failure to give such notification. Tenders of Private
Notes will not be deemed to have been made until such defects or irregularities
have been cured or waived. Any Private Notes received by the Exchange Agent that
are not properly tendered and as to which the defects or irregularities have not
been cured or waived will be returned by the Exchange Agent to the tendering
Holders of Private Notes, unless otherwise provided in this Letter of
Transmittal, as soon as practicable following the Expiration Date.
 
     2. TENDER BY HOLDER.  Only a Holder of Private Notes may tender such
Private Notes in the Exchange Offer. Any beneficial holder of Private Notes who
is not the registered Holder and who wishes to tender should arrange with the
registered Holder to execute and deliver this Letter of Transmittal on his
behalf or must, prior to completing and executing this Letter of Transmittal and
delivering his Private Notes, either make appropriate arrangements to register
ownership of the Private Notes in such holder's name, or obtain a properly
completed bond power from the registered Holder. The transfer of registered
ownership of Private Notes may take considerable time.

     3. PARTIAL TENDERS.  If less than the entire principal amount of Private
Notes represented by a certificate is tendered, the tendering Holder should fill
in the aggregate principal amount tendered in the third column of the box
entitled "Description of Private Notes" above. The entire principal amount of
Private Notes set forth on the certificate delivered to the Exchange Agent will
be deemed to have been tendered unless otherwise indicated. If the entire
principal amount of all Private Notes is not tendered, then a Private Notes
certificate for the principal amount of Private Notes not tendered and a
certificate or certificates representing Exchange Senior Notes issued in
exchange for any Private Notes accepted will be sent to the Holder at his or her
registered address, unless a different address is provided in the appropriate
box on this Letter of Transmittal, promptly after the Private Notes are accepted
for exchange, or in the case of Private Notes tendered by book-entry transfer,
such untendered Private Notes and Exchange Senior Notes issued in exchange for
any Private Notes accepted will be credited to accounts at DTC.
 
     4. SIGNATURES ON THE LETTER OF TRANSMITTAL; BOND POWERS AND ENDORSEMENTS;
GUARANTEE OF SIGNATURES.  If this Letter of Transmittal (or facsimile hereof) is
signed by the record Holder(s) of the Private Notes tendered hereby, the
signature must correspond with the name(s) as written on the face of the Private
Notes without alteration, enlargement, or any change whatsoever.
 
     If this Letter of Transmittal (or facsimile hereof) is signed by the
registered Holder or Holders of Private Notes tendered and the certificate or
certificates for Exchange Senior Notes issued in exchange therefor are to be
issued (or if certificates representing the principal amount of Private Notes
not tendered are to be reissued) to the registered Holder, the said Holder need
not and should not endorse any tendered Private Notes, nor provide a separate
bond power. In any other case, such Holder must either properly endorse the
Private Notes tendered or transmit a properly completed separate bond power with
this Letter of Transmittal, with the signatures on the endorsement or bond power
guaranteed by an Eligible Institution.
 
     If this Letter of Transmittal (or facsimile hereof) is signed by a person
other than the registered Holder or Holders of any Private Notes listed, such
Private Notes must be endorsed or accompanied by appropriate bond powers, in
each case signed as the name of the registered Holder or Holders appears on the
Private Notes.
 
     If this Letter of Transmittal (or facsimile hereof) or any Private Notes or
bond powers are signed by trustees, executors, administrators, guardians,
attorneys-in-fact, officers of corporations, or others acting in a fiduciary or
representative capacity, such persons should so indicate when signing, and,
unless waived by the Company, evidence satisfactory to the Company of their
authority so to act must be submitted with this Letter of Transmittal.
 
     Endorsements on Private Notes or signatures on bond powers required by this
Instruction 4 must be guaranteed by an Eligible Institution.
 
     Except as otherwise provided below, all signatures on this Letter of
Transmittal must be guaranteed by a participant in a Recognized Signature
Guarantee Medallion Program (an "Eligible Institution"). Signatures on this
Letter of Transmittal need not be guaranteed if (i) this Letter of Transmittal
is signed by the registered Holder(s) of the Private Notes tendered herewith and
such Holder(s) have not completed the box set forth herein entitled "Special
Payment Instructions" or the box entitled "Special Delivery Instructions," or
(ii) if such Private Notes are tendered for the account of an Eligible
Institution.
 
     5. SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS.  Tendering Holders should
indicate, in the applicable box or boxes, the name and address to which Exchange
Senior Notes or substitute Private Notes for the principal amount of Private
Notes not tendered or not accepted for exchange are to be issued or sent, if
different from the name and address of the person signing this Letter of
Transmittal. In the case of issuance in a different name, the taxpayer
identification or social security number of the person named must also be
indicated.
 
     6. TRANSFER TAXES.  The Company will pay all transfer taxes, if any,
applicable to the exchange of Private Notes pursuant to the Exchange Offer. If,
however, certificates representing Exchange Senior Notes or Private Notes (for
any principal amount of Private Notes not tendered or accepted for exchange) are
to be delivered to, or are to be registered or issued in the name of, any person
other than the registered Holder of the Private Notes tendered hereby, or if
tendered Private Notes are registered in the name of any person other than the
person signing this Letter of Transmittal, or if a transfer tax is imposed for
any reason other than the exchange of Private Notes pursuant to the Exchange
Offer, then the amount of any such transfer taxes (whether imposed on the
registered Holder or on any other persons) will be payable by the tendering
Holder. If satisfactory evidence of payment of such taxes or exemption therefrom
is not submitted with this Letter of Transmittal, the amount of such transfer
taxes will be billed directly to such tendering Holder.
 
     Except as provided in this Instruction 6, it will not be necessary for
transfer tax stamps to be affixed to the Private Notes listed in this Letter of
Transmittal.
 
     7. FORM W-9.  Any Holder who tenders his Private Notes is required to
provide the Exchange Agent with a correct Taxpayer Identification Number ("TIN")
on the Form W-9 which is enclosed herewith. If such Holder is an individual, the
TIN is his or her social security number. Failure to provide the information on
the Form W-9 may subject

<PAGE>   10
 
the surrendering Holder to 31% Federal income tax withholding on any payment
made to Holders of the Exchange Senior Notes. Exempt Holders (including, among
others, all corporations and certain foreign individuals) are not subject to
these backup withholding and reporting requirements. For additional information
in this regard, please refer to the enclosed Guidelines for Certification of TIN
on Substitute Form W-9. In order to satisfy the Exchange Agent that a foreign
individual qualifies as an exempt recipient, the Holder must submit a Form W-8,
signed under penalties of perjury, attesting to that individual's exempt status.
A Form W-8 may be obtained from the Exchange Agent.
 
     8. WAIVER OF CONDITIONS.  The Company reserves the absolute right to amend,
waive, or modify specified conditions in the Exchange Offer, set forth in the
Prospectus under the caption "The Exchange Offer -- Conditions," in the case of
any Private Notes tendered.
 
     9. MUTILATED, LOST, STOLEN OR DESTROYED PRIVATE NOTES.  Any tendering
Holder whose Private Notes have been mutilated, lost, stolen, or destroyed
should contact the Exchange Agent at the address indicated herein for further
instructions.
 
     10. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Questions and requests
for assistance and requests for additional copies of the Prospectus or this
Letter of Transmittal may be directed to the Exchange Agent at the address
specified in the Prospectus. Holders may also contact their broker, dealer,

not furnish a Taxpayer Identification Number to a payer. Certain penalties may
also apply.

(1) PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER -- If you fail

    reasonable cause and not to willful neglect.
 
(2) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING -- If you
    make a false statement with no reasonable basis which results in no
    imposition of backup withholding, you are subject to a penalty of $500.
 
(3) CRIMINAL PENALTY FOR FALSIFYING INFORMATION -- Falsifying certifications or
    affirmations may subject you to criminal penalties including fines and/or
    imprisonment. FOR ADDITIONAL INFORMATION CONTACT YOUR TAX CONSULTANT OR THE
    IRS.
