II.  SUMMARY

     This summary highlights basic information about Nextel and the exchange
offer, but does not contain all information important to you. You should read
the more detailed information and consolidated financial statements and the
related notes appearing elsewhere in this prospectus and incorporated by
reference into this prospectus.

  A.  NEXTEL

     Nextel provides a wide array of digital wireless communications services
throughout the United States. Nextel offers a differentiated, integrated package
of digital wireless communications services under the Nextel brand name,
primarily to business users. Nextel's digital mobile network constitutes one of
the largest integrated wireless communications systems utilizing a single
transmission technology in the United States.

     A customer using Nextel's digital mobile network is able to access:

        - digital mobile telephone service;

        - digital two-way radio dispatch service, which provides instant
          conferencing capabilities and is marketed as "Nextel Direct Connect"
          service;

        - paging; and

        - short-messaging service.

     Nextel refers to the handset device on which it delivers these services as
a subscriber unit.

        As of September 30, 1999:

        - Nextel provided service to about 4,050,900 digital subscriber units in
          the United States; and

        - Nextel's digital mobile network or the compatible digital mobile
          network of Nextel Partners, Inc., a joint venture in which Nextel is a
          participant, was operational in areas in and around 92 of the top 100
          metropolitan statistical areas in the United States.

     Nextel has also announced its plans to offer its customers access to new
digital two-way mobile data and Internet connectivity services. Three new
handsets developed and manufactured by Motorola, the "i1000plus," the "i500plus"
and the "i700plus," have been introduced since May 1999. These new handsets are
expected to be the first in a product line that incorporates micro-browsers and
wireless Internet capability, which is planned to be combined with other mobile
data applications to be used in connection with Nextel's planned wireless data
service offering. Nextel has begun testing the underlying technology for these
services in several U.S. markets and currently plans to commercially launch the
wireless data service offering in mid-2000.

     In addition to its domestic operations, Nextel has ownership interests in
international wireless companies through its subsidiary, Nextel International,
Inc. The subsidiaries of Nextel International, Inc., or other entities in which
Nextel International, Inc. holds equity or equivalent interests, own and operate
wireless communications systems in and around various major metropolitan market
areas in Latin America, Asia and Canada. Nextel International, Inc., together
with Nextel, provides services in ten of the world's 25 largest cities.

     Nextel's principal executive and administrative facility is located at 2001
Edmund Halley Drive, Reston, Virginia 20191, and its telephone number is (703)
433-4000.

  B.  USE OF PROCEEDS

      Nextel will not receive any cash proceeds from the exchange offer.

  C.  THE EXCHANGE OFFER

The Exchange Offer.........  Nextel offers to exchange $2.0 billion in principal
                             amount of its 9.375% senior serial redeemable notes
                             due November 15, 2009, which have been registered
                             under the federal securities laws, for $2.0 billion
                             principal amount of its outstanding unregistered
                             9.375% senior serial redeemable notes due November
                             15, 2009 which Nextel issued on November 12, 1999
                             in a private placement. You have the right to
                             exchange your outstanding notes for an equal
                             principal amount of exchange notes with
                             substantially identical terms.

                             In order for your outstanding notes to be
                             exchanged, you must properly tender them prior to
                             the expiration of the exchange offer. All
                             outstanding notes that are validly tendered and not
                             validly withdrawn before the expiration of the
                             exchange offer will be exchanged. Nextel will issue
                             the exchange notes on or promptly after the
                             expiration of the exchange offer.

Registration Rights
Agreement..................  Nextel sold the outstanding notes on November 12,
                             1999 in a private placement. At that time, Nextel
                             signed a registration rights agreement with the
                             initial purchasers of the notes, which requires
                             Nextel to conduct this exchange offer.

                             This exchange offer is intended to satisfy those
                             registration rights set forth in the registration
                             rights agreement. After the exchange offer is
                             complete, you will no longer be entitled to
                             registration rights with respect to outstanding
                             notes you do not exchange.

If You Fail to Exchange
Your Outstanding Notes.....  If you do not exchange your outstanding notes for
                             exchange notes in the exchange offer, you will
                             continue to be subject to the restrictions on
                             transfer as provided in the outstanding notes and
                             the indenture governing those notes. In general,
                             you may not offer or sell your outstanding notes
                             unless the offer or sale is registered under the
                             federal securities laws or unless those notes are
                             sold in a transaction exempt from or not subject to
                             the registration requirements of the federal
                             securities laws and applicable state securities
                             laws.


Expiration Date............  The exchange offer will expire at 5:00 p.m., New
                             York City time, on February 10, 2000 unless Nextel
                             decides to extend the expiration date.


Conditions to the Exchange
Offer......................  The exchange offer is subject to conditions which
                             Nextel may waive. The exchange offer is not
                             conditioned upon any minimum amount of outstanding
                             notes being tendered for exchange.

                             Nextel reserves the right, subject to applicable
                             law, at any time and from time to time:

                                  - to delay the acceptance of the outstanding

                                    respect.

                                    either (1) with the outstanding notes to be
                                    tendered or (2) in compliance with the
                                    specified procedures for guaranteed delivery
                                    of the outstanding notes.

                             Brokers, dealers, commercial banks, trust companies
                             and other nominees may also effect tenders by
                             book-entry transfer.

                             Please do not send your letter of transmittal or
                             certificates representing your outstanding notes to
                             Nextel. Those documents should only be sent to the
                             exchange agent. Questions regarding how to tender
                             and requests for information should be directed to
                             the exchange agent.

Special Procedures for
Beneficial Owners..........  If your outstanding notes are registered in the
                             name of a broker, dealer, commercial bank, trust
                             company or other nominee, Nextel urges you to
                             contact that person promptly if you wish to tender
                             your outstanding notes pursuant to the exchange
                             offer.

                             notes at any time prior to the expiration date of
                             the exchange offer by delivering a written notice
                             of your withdrawal to the exchange agent. You must
                             also follow the withdrawal procedures as described
                             under the heading "V.I. The Exchange
                             Offer -- Withdrawal of Tenders."

Resales of Exchange
Notes......................  Nextel believes that you will be able to offer for
                             resale, resell or otherwise transfer exchange notes
                             issued in the exchange offer without compliance
                             with the registration and prospectus delivery
                             provisions of the federal securities laws, provided
                             that:

                                  - you are acquiring the exchange notes in the
                                    ordinary course of business;

                                  - you are not participating, and have no
                                    arrangement or understanding with any person
                                    to participate, in the distribution of the
                                    exchange notes; and

                                  - you are not an affiliate of Nextel. An
                                    affiliate of Nextel is a person that
                                    "controls or is controlled by or is under
                                    common control with" Nextel.

                             Nextel's belief is based on interpretations by the
                             Staff of the Commission, as set forth in no-action
                             letters issued to third parties unrelated to
                             Nextel. The Staff has not considered this exchange
                             offer in the context of a no-action letter, and
                             Nextel cannot assure you that the Staff would make
                             a similar determination with respect to this
                             exchange offer.

<PAGE>   8

                             If Nextel's belief is not accurate and you transfer
                             an exchange note without delivering a prospectus
                             meeting the requirements of the federal securities
                             laws or without an exemption from these laws, you
                             may incur liability under the federal securities
                             laws. Nextel does not and will not assume or
                             indemnify you against this liability.

                             Each broker-dealer that receives exchange notes for
                             its own account in exchange for outstanding notes
                             which were acquired by such broker-dealer as a
                             result of market-making or other trading activities
                             must agree to deliver a prospectus meeting the
                             requirements of the federal securities laws in
                             connection with any resale of the exchange notes by
                             that broker-dealer.

Exchange Agent.............  The exchange agent for the exchange offer is Harris
                             Trust and Savings Bank. The address, telephone
                             number and facsimile number of the exchange agent
                             are set forth in "V.K. The Exchange
                             Offer -- Exchange Agent" and in the letter of
                             transmittal.

  D.  THE EXCHANGE NOTES

Exchange Notes.............  $2.0 billion principal amount of Nextel's 9.375%
                             senior serial redeemable notes due November 15,
                             2009.

Interest Payment Dates.....  Interest on the notes accrues at the rate of 9.375%
                             per year, payable in cash every six months on May
                             15 and November 15, with the first payment on May
                             15, 2000.

Optional Redemption........  On or after November 15, 2004, Nextel may redeem
                             some or all of the notes at the redemption prices
                             set forth in this prospectus, plus accrued and
                             unpaid interest, if any, to the date of redemption.
                             In addition, if Nextel sells on or before November
                             15, 2002 at least $50 million of qualifying capital
                             stock, it may redeem up to 35% in principal amount
                             of the notes at a price of 109.375% of their
                             principal amount, plus accrued and unpaid interest,
                             if any, to the date of redemption with the proceeds
                             from that sale as long as any redemption occurs
                             within 180 days of the sale of the capital stock.

Ranking....................  The exchange notes will not be secured debt of
                             Nextel and:

                                  - will rank equal in right of payment to all
                                    Nextel's existing and future senior
                                    unsecured debt;

                                  - will effectively rank equal in right of
                                    payment with obligations arising out of
                                    Nextel's unsecured guarantees of debt of its
                                    subsidiaries;

                                  - will be senior in right of payment to all
                                    existing and future subordinated debt of
                                    Nextel;

                                  - will be effectively subordinated to all
                                    existing and future debt of Nextel's
                                    subsidiaries; and

                                  - will be subordinated to all existing and
                                    future secured debt of Nextel.

                             At September 30, 1999, Nextel had about $5.1
                             billion of outstanding debt that ranked equally
                             with the notes. At September 30, 1999,

                                        7
<PAGE>   9

                             Nextel's subsidiaries had about $4.7 billion of
                             outstanding debt and current liabilities, including
                             trade payables.

Covenants..................  The indenture governing the notes contains
                             covenants which restrict, among other things, the
                             ability of Nextel and some of its subsidiaries to:

                                  - incur more debt;

                                  - pay dividends or make distributions on their
                                    stock, other than Nextel's currently
                                    authorized preferred stock;

                                  - make investments or restricted payments;

                                  - enter into specified transactions with
                                    affiliates;

                                  - merge or consolidate; and

                                  - transfer and sell assets.

Change of Control..........  Upon a change of control, as defined later in this
                             prospectus, Nextel will be required to offer to
                             repurchase your notes at a price equal to 101% of
                             their principal amount plus accrued and unpaid
                             interest, if any, to the date of purchase.

     See "VI. The Exchange Notes" for more detailed information concerning the
exchange notes.

Risk Factors...............  You should read the "Risk Factors" section
                             beginning on page 11 of this prospectus, as well as
                             other cautionary statements throughout the entire
                             prospectus, to ensure that you understand the risks
                             associated with the notes.

  E.  SUMMARY FINANCIAL INFORMATION


     The financial information below for the nine months ended December 31,
1994, which reflects the change in Nextel's fiscal year end from March 31 to
December 31, and the years ended December 31, 1995, 1996, 1997 and 1998 have
been derived from the audited consolidated financial statements of Nextel. The
financial information for the nine months ended September 30, 1998 and 1999 has
been derived from the unaudited financial statements of Nextel and reflects only
normal recurring adjustments necessary for the fair presentation of this
information. You should not expect the results of operations of interim periods
to be an indication of results for a full year. This information is only a
summary and should be read in conjunction with Nextel's historical financial
statements contained in reports filed with the Commission. See "XI.A. Where You
Can Get More Information -- Available Information."


     Acquisitions. Nextel's results were affected by business combinations,
acquisitions and investments involving both domestic and international
companies. In July 1995, Nextel completed the acquisition of substantially all
of Motorola's 800 MHz specialized mobile radio licenses in the continental
United States and mergers with OneComm Corporation and American Mobile Systems,
Incorporated. Additional information regarding acquisitions completed in 1996,
1997 and 1998 can be found in note 2 to the consolidated financial statements in
Nextel's Annual Report on Form 10-K for the year ended December 31, 1998.

     Income Tax Provision. As a result of operating results and the change in
useful lives of some intangible assets, Nextel increased its valuation allowance
for deferred tax assets resulting in a tax provision of about $259 million in
1997. Additional information can be found in note 10 to the consolidated
financial statements in Nextel's Annual Report on Form 10-K for the year ended
December 31, 1998.

     Ratio of Earnings to Fixed Charges.  For the purpose of computing the ratio
of earnings to fixed charges, earnings consist of loss before income taxes plus
fixed charges less capitalized interest and less income (loss) from equity
method investments and loss (income) attributable to minority interests. Fixed
charges consist of:

        - interest on all indebtedness and amortization of deferred financing
          costs and amortization of original issue discount; and

        - that portion of rental expense which Nextel believes to be
          representative of interest.

The deficiency of earnings to cover fixed charges for the nine months ended
December 31, 1994 was $218 million, for the year ended December 31, 1995 was
$563 million, for the year ended December 31, 1996 was $885 million, for the
year ended December 31, 1997 was $1,342 million, for the year ended December 31,
1998 was $1,771 million, for the nine months ended September 30, 1998 was $1,319
million and for the nine months ended September 30, 1999 was $1,041 million.


     As Adjusted. At September 30, 1999, the as adjusted balance sheet data
reflects the receipt of the estimated net proceeds from the sale of 33,781,785
shares of Class A common stock of about $2.8 billion in a public offering
completed on November 5, 1999, as well as the estimated net proceeds of the
offering of the outstanding notes on November 12, 1999 of about $2.0 billion,
but does not reflect the expected repurchase or redemption of Nextel's public
notes that were issued prior to 1997, nor the expected extraordinary loss that
would result from the extinguishment of that debt. As of December 31, 1999, in
accordance with the provisions of the relevant indentures, Nextel redeemed all
outstanding senior notes in three of the series of senior notes and Nextel
delivered notices and other appropriate documents to the trustee commencing the
redemption of all outstanding senior notes in the remaining two series issued
prior to 1997. The notes redeemed and called for redemption represented an
aggregate carrying value of $1,617 million in long term indebtedness on Nextel's
September 30, 1999 balance sheet, and the remaining two redemptions are
scheduled for closing on January 15, 2000 and February 15, 2000.



     You should review notes 12 and 13 to the consolidated financial statements
in Nextel's Annual Report on Form 10-K for the year ended December 31, 1998 for
a detailed discussion of Nextel's capital stock.

III.  RISK FACTORS

     You should carefully consider the risk factors discussed below, as well as
other information included and incorporated by reference in this prospectus in
connection with an investment in the exchange notes.

  A.  RISK FACTORS RELATING TO NEXTEL

     1. NEXTEL HAS A HISTORY OF NET LOSSES AND NEGATIVE CASH FLOW AND MAY NEVER
        BE ABLE TO SATISFY ITS CASH NEEDS FROM OPERATIONS.

     Nextel has never been profitable and has experienced negative cash flow
since its start in 1987. If these losses continue, Nextel's ability to pay cash
interest and to make scheduled principal repayments, on its indebtedness,
including the notes, may be adversely affected. Nextel had net losses
attributable to common stockholders of about $1.8 billion during 1998 and about
$1.2 billion for the nine months ended September 30, 1999. Nextel's accumulated
deficit was about $5.4 billion at September 30, 1999. Nextel expects that losses
will continue over the next several years. Nextel cannot know when, if ever, net
cash generated by its internal business operations will support its growth and
continued operations.

     2. IF NEXTEL DOES NOT OBTAIN SUFFICIENT ADDITIONAL FINANCING COMMITMENTS TO
        MEET ITS LONG-TERM NEEDS, NEXTEL'S ABILITY TO PAY INTEREST AND TO MAKE
        PRINCIPAL PAYMENTS ON THE NOTES MAY BE ADVERSELY AFFECTED.

          A. REASONS NEXTEL WILL NEED CASH.

     Nextel anticipates that it will need substantial amounts of cash for:

     - capital expenditures to build and enhance its digital mobile network;

     - operating expenses relating to its digital mobile network;

     - potential acquisitions, including negotiated acquisitions of spectrum
       from third parties and any future Federal Communications Commission
       auctions of spectrum;

     - debt service requirements; and

     - other general corporate expenditures.

     If Nextel can't fund these needs, its growth plans and operations, and
Nextel's ability to pay cash interest, and to make scheduled principal
repayments, on its indebtedness, including the notes, may be adversely affected.
Nextel expects its cash needs will exceed its cash flows from operating
activities through 2000. In addition, Nextel may need to revise its business
plan to respond to competitive and other factors, so its need for cash may
increase.

          B. NEXTEL'S CURRENT CREDIT FACILITIES ARE LIMITED AND CONTAIN
             RESTRICTIONS ON ADDITIONAL FINANCINGS THAT MAY RESTRICT GROWTH AND
             ADVERSELY AFFECT OPERATIONS.

     Nextel's long-term cash needs may be much greater than its cash on hand and
availability under its existing financing agreements. As a result, Nextel may
have to raise substantial amounts of additional funds, in the form of equity or
debt, in the future to support its growth and operations. If it is unable to do
so, Nextel may not be able to expand the coverage and capacity of its network to
meet the demands of Nextel's anticipated growth. Nextel's inability to achieve
contemplated levels of growth would adversely affect its financial results and
may adversely affect Nextel's ability to pay cash interest, and to make
scheduled principal repayments, on its indebtedness, including the notes.

     Under its bank credit agreement as amended effective November 12, 1999,
Nextel may borrow up to $5.0 billion in secured financing from its bank lenders
provided that Nextel satisfies financial and other conditions. As of September
30, 1999, about $1.8 billion of this secured financing had been drawn under the
bank credit agreement as in effect prior to its amendment. As of November 12,
1999, Nextel had about $2.7 billion of debt outstanding under the amended bank
credit agreement. The availability of this financing is also subject to Nextel
satisfying covenants under indentures relating to Nextel's other public
                                       11
<PAGE>   13

notes. Nextel's access to additional funds may be limited by the terms of its
existing financing agreements, including:

     - covenants that restrict the amount of additional borrowings, including
       additional borrowings under existing financing arrangements;

     - covenants that restrict Nextel's grant of liens on assets that affect
       Nextel's ability to obtain new secured financing; and

     - existing debt service requirements.

          c. FUNDING REQUIREMENTS FOR INTERNATIONAL OPERATIONS AND GROWTH MAY
             CAUSE EVEN GREATER CASH NEEDS, WHICH MAY RESULT IN LESS FUNDING
             AVAILABLE FOR NEXTEL'S DOMESTIC GROWTH AND OPERATIONS.


     Based on Nextel International, Inc.'s assessment of the business activity
and related cash needs of its operating subsidiaries that are controlled by or
that rely substantially on Nextel International, Inc. for further funding,
Nextel International, Inc. believes that it will have adequate funding to
continue its operations only through the early portion of 2000. Nextel,
therefore, currently expects that it may need to fund a significant portion of
Nextel International, Inc.'s funding needs in 2000. This would increase Nextel's
own cash needs, which could result in a lesser amount of cash available to
Nextel for domestic use.



          d. FUNDING REQUIREMENTS FOR A NEXTEL-SPONSORED REORGANIZATION OF THE
             NEXTWAVE ENTITIES OR ACQUISITION OF SPECTRUM INITIALLY AWARDED TO
             NEXTWAVE MAY REQUIRE NEXTEL TO RAISE ADDITIONAL CAPITAL.



     If a Nextel-sponsored plan of reorganization of the NextWave entities is
implemented, or if Nextel were otherwise to acquire spectrum initially awarded
to NextWave, Nextel anticipates that it would need to raise a substantial amount
of additional capital to finance the cash distributions under that plan or
acquisition and to pursue the business opportunities arising from any such
transaction. Nextel cannot assure you that any plan involving Nextel in a
reorganization of the NextWave entities or acquisition of spectrum initially
awarded to NextWave will be implemented or that the necessary additional capital
for that purpose will be available on acceptable terms, or at all. If sufficient
additional capital is not available, Nextel may be unable to complete any such
reorganization or acquisition or the amount of funding available to Nextel for
its existing businesses would be reduced.


          e. OTHER FACTORS MAY ADVERSELY AFFECT NEXTEL'S ACCESS TO ADDITIONAL
             FINANCING AND NEXTEL MAY HAVE TO CURTAIL ITS BUSINESS IF IT CANNOT
             ACCESS ADDITIONAL FUNDING.

     Nextel's access to additional funds also may be limited by:

        - general market conditions that adversely affect the availability or
          cost of financings;

        - market conditions affecting the telecommunications industry in
          general; and

        - specific factors affecting Nextel's attractiveness as a borrower or
          investment vehicle, including:

           (1) the terms of Nextel's arrangements with Motorola that relate to
               Motorola's ownership interest in Nextel, and the terms of options
               and warrants issued to others, that may make equity financings
               more difficult;

           (2) the ability to relocate current spectrum licensees from some
               frequencies in order to remove them from spectrum as to which
               Nextel was the highest bidder at an auction;

           (3) the potential commercial opportunities and risks associated with
               implementation of Nextel's business plan;

           (4) the market's perception of Nextel's performance and assets; and

           (5) the actual amount of cash needed by Nextel to pursue its business
               strategy.
                                       12
<PAGE>   14

          F. FUNDING FOR NEXTEL'S CAPITAL NEEDS IS NOT ASSURED AND NEXTEL MAY
             HAVE TO CURTAIL ITS BUSINESS IF IT CANNOT FIND ADEQUATE FUNDING.

     Currently, Nextel has no legally binding commitments or understandings with
any third parties to obtain any material amount of additional equity or debt
financing. Nextel cannot assure you that it will be able to obtain any
additional financing in the amounts or at the times that it may require the
financing, or if Nextel does obtain any financing, that it would be on
acceptable terms. As a result, Nextel cannot assure you that it will have
adequate capital to implement the contemplated expansion and enhancement of its
digital mobile network, to maintain its current levels of operation or to pursue
strategic acquisitions or other opportunities to increase its spectrum holdings.
Nextel's failure to obtain sufficient additional financing could result in the
delay or abandonment of some or all of its development, expansion and
acquisition plans and expenditures, which could have an adverse effect on Nextel
and on Nextel's ability to pay cash interest, and to make scheduled principal
repayments, on its indebtedness, including the notes.

     3. NEXTEL'S FUTURE PERFORMANCE WILL DEPEND ON ITS ABILITY TO SUCCEED IN THE
        HIGHLY COMPETITIVE WIRELESS COMMUNICATIONS INDUSTRY.

     Nextel's ability to compete effectively with established and prospective
wireless communications service providers depends on many factors, including:

     - IF NEXTEL'S WIRELESS COMMUNICATIONS TECHNOLOGY DOES NOT PERFORM IN A
       MANNER THAT MEETS CUSTOMER EXPECTATIONS, NEXTEL WILL BE UNABLE TO ATTRACT
       AND RETAIN CUSTOMERS, WHICH WOULD ADVERSELY AFFECT NEXTEL'S ABILITY TO
       PAY INTEREST AND TO MAKE PRINCIPAL PAYMENTS ON THE NOTES. Customer
       acceptance of the services Nextel offers is and will continue to be
       affected by technology-based differences and by the operational
       performance and reliability of system transmissions on Nextel's digital
       mobile network. If Nextel is unable to address and resolve satisfactorily
       performance or other transmission quality issues as they arise, or if
       these issues limit Nextel's ability to expand its network coverage or
       capacity as currently planned, or if these issues were to place Nextel at
       a competitive disadvantage to other wireless service providers in its
       markets, Nextel may have difficulty attracting and retaining customers,
       which would adversely affect Nextel's ability to pay cash interest, and
       to make scheduled principal repayments, on its indebtedness, including
       the notes.

     - IF NEXTEL CANNOT EXPAND, PROVIDE AND MAINTAIN ITS SYSTEM COVERAGE, THEN
       ITS GROWTH AND OPERATIONS, AND NEXTEL'S ABILITY TO PAY INTEREST AND TO
       MAKE PRINCIPAL PAYMENTS ON THE NOTES, WOULD BE ADVERSELY AFFECTED. Nextel
       will not be able to provide roaming system coverage comparable to that
       currently available through roaming arrangements from cellular and some
       personal communication services operators, unless and until a nationwide
       digital mobile network build-out is substantially completed. This places
       Nextel at a competitive disadvantage, as some other providers currently
       have roaming agreements that provide coverage of each other's markets
       throughout the United States, including areas where Nextel's network has
       not been or will not be built. In addition, some of Nextel's competitors
       provide their customers with subscriber units with both digital and
       analog capability, which expands their coverage, while Nextel has only
       digital capability. Nextel cannot assure you that it will be able to
       achieve sufficient system coverage or that a sufficient number of
       customers or potential customers will be willing to accept system
       coverage limitations as a trade-off for the enhanced multi-function
       wireless communications package Nextel provides on its nationwide digital
       mobile network.

     - NEXTEL DOES NOT HAVE THE EXTENSIVE DIRECT AND INDIRECT CHANNELS OF
       DISTRIBUTION FOR ITS DIGITAL MOBILE NETWORK PRODUCTS AND SERVICES THAT
       SOME OF ITS COMPETITORS HAVE, WHICH MAY ADVERSELY AFFECT NEXTEL'S
       OPERATING RESULTS AND COULD ADVERSELY AFFECT NEXTEL'S ABILITY TO PAY
       INTEREST AND TO MAKE PRINCIPAL PAYMENTS ON THE NOTES. Many of Nextel's
       competitors have established extensive networks of retail locations and
       multiple distribution channels, and so enjoy a competitive advantage over
       Nextel in these areas. Nextel has increased the proportion of its digital
       mobile network customers that it obtains through its indirect distributor
       network, and Nextel currently anticipates that it will rely more heavily
       on indirect distribution channels to achieve greater market penetration
                                       13
<PAGE>   15

       for its digital wireless service offerings. However, as Nextel expands
       its retail subscriber base through increased reliance on indirect
       distribution channels and as price competition in the wireless industry
       intensifies, Nextel's average revenue per digital subscriber unit may
       decrease and Nextel's customer retention may be adversely affected.

     - NEXTEL'S INABILITY TO MAINTAIN PRICING PACKAGES ATTRACTIVE TO CUSTOMERS
       MAY ADVERSELY AFFECT OPERATING RESULTS, WHICH COULD ADVERSELY AFFECT
       NEXTEL'S ABILITY TO PAY INTEREST AND TO MAKE PRINCIPAL PAYMENTS ON THE
       NOTES.

             A. SOME OF NEXTEL'S COMPETITORS ARE FINANCIALLY STRONGER THAN
                NEXTEL, WHICH ALLOWS THEM TO PRICE THEIR SERVICE PACKAGES AT
                LEVELS BELOW THOSE THAT NEXTEL CAN OR IS WILLING TO MATCH.

         Nextel's ability to compete based on the price of its digital mobile
      network subscriber units and service offerings will be limited. This could
      adversely affect Nextel's growth and Nextel's ability to pay cash
      interest, and to make scheduled principal repayments, on its indebtedness,
      including the notes.

             B. NEXTEL'S EQUIPMENT IS MORE EXPENSIVE THAN SOME COMPETITORS'
                WHICH MAY ADVERSELY AFFECT GROWTH AND OPERATING RESULTS.

         Nextel currently markets multi-function digital subscriber handsets,
      providing mobile telephone and private and group dispatch service, in
      addition to paging and alphanumeric short-text messaging. Nextel's
      handsets are, and are likely to remain, significantly more expensive than
      analog handsets and are, and are likely to remain, somewhat more expensive
      than digital cellular or personal communication services handsets that do
      not incorporate a comparable multi-function capability. Although Nextel
      believes that its multi-function subscriber handsets currently are
      competitively priced compared to multi-function digital cellular and
      personal communication services handsets, the higher cost of Nextel's
      equipment may make it more difficult or less profitable to attract
      customers who do not place a high value on Nextel's unique multi-service
      offering. This may reduce Nextel's growth opportunities or profitability
      and may adversely affect Nextel's ability to pay cash interest, and to
      make scheduled principal repayments, on its indebtedness, including the
      notes.

                 C. NEXTEL MAY FACE CONTINUING PRESSURE TO REDUCE PRICES, WHICH
                    WOULD ADVERSELY AFFECT OPERATING RESULTS AND NEXTEL'S
                    ABILITY TO PAY INTEREST AND TO MAKE PRINCIPAL PAYMENTS ON
                    THE NOTES.

         Over the past several years as the number of wireless communications
      providers in Nextel's market areas has increased, its competitors' prices
      in these markets have generally decreased. Nextel may encounter further
      market pressures to:

         - reduce its digital mobile network service offering prices;

         - restructure its digital mobile network service offering packages to
           offer more value;

         - respond to particular short term, market specific situations, for
           example, special introductory pricing or packages that may be offered
           by new providers launching their service in a particular market; or

         - remain competitive if wireless service providers generally continue
           to reduce the prices charged to their customers.

     - NEXTEL'S EFFORTS TO KEEP PACE WITH TECHNOLOGICAL CHANGE MAY BE
       UNSUCCESSFUL OR MAY ADVERSELY AFFECT OPERATING RESULTS, WHICH WOULD
       ADVERSELY AFFECT NEXTEL'S ABILITY TO PAY INTEREST AND TO MAKE PRINCIPAL
       PAYMENTS ON THE NOTES.  Nextel's digital technology could become
       obsolete. Nextel relies

                                       14
<PAGE>   16

       on digital technology that is not compatible with, and competes with,
       other forms of digital and non-digital voice communication technology.
       Competition among these differing technologies can:

         - segment the user markets, which could reduce demand for specific
           technologies, including Nextel's;

         - reduce the resources devoted by third party suppliers, including
           Motorola, which supplies all of Nextel's current digital technology,
           in developing or improving the technology for Nextel's systems; and

         - adversely affect market acceptance of Nextel's services.

         Nextel cannot assure you that its digital voice technology will
      successfully compete with the other forms of digital and non-digital voice
      communication systems. Further, new digital or non-digital voice
      communication transmission technology may develop that will cause Nextel's
      existing systems technology to be obsolete or otherwise impair market
      acceptance of its technology.

     - NEXTEL'S GROWTH MAY EXCEED THE CAPABILITIES OF ITS SYSTEMS, HURTING ITS
       PERFORMANCE AND NEXTEL'S ABILITY TO PAY INTEREST AND TO MAKE PRINCIPAL
       PAYMENTS ON THE NOTES.

                 A. NEXTEL FACES LIMITATIONS ON ITS ABILITY TO INCREASE
                    SUBSCRIBERS, WHICH CAN LIMIT ITS GROWTH AND PERFORMANCE.

         Nextel's ability to continue to increase the number of subscribers on
      its digital mobile network depends on a variety of factors, including:

         - the ability to successfully plan for additional system capacity at
           levels needed to meet anticipated new subscribers and the related
           increases in system usage;

         - the ability to obtain additional radio spectrum when and where
           required; and

         - the availability of a sufficient quantity of cell sites, system
           infrastructure equipment and subscriber units, of the appropriate
           models and types, to meet the demands and preferences of potential
           subscribers to the digital mobile network.

                 B. NEXTEL MAY FACE LIMITATIONS ON AVAILABILITY OF CELL SITES
                    AND EQUIPMENT, WHICH MAY ADVERSELY AFFECT ITS GROWTH AND
                    PERFORMANCE.

         Although Nextel believes it has secured sufficient cell sites at
      appropriate locations in its markets to meet planned system coverage and
      capacity targets, Nextel cannot assure you that it will meet those needs
      in the future. Nextel generally 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, but Nextel cannot assure you that quantities will be
      sufficient in the future. Additionally, Nextel has contractual
      arrangements with Nextel International, Inc. and Nextel Partners, Inc.
      that contemplate that, in the event of shortages of that equipment,
      available supplies would be allocated proportionately among Nextel and
      those entities.

                 C. NEXTEL HAS POTENTIAL SYSTEMS LIMITATIONS ON ADDING
                    CUSTOMERS, WHICH MAY ADVERSELY AFFECT ITS GROWTH AND
                    PERFORMANCE.

         Other factors affecting Nextel's ability to successfully add customers
      to its digital mobile network include:

         - the adequacy and efficiency of Nextel's information systems, business
           processes and related support functions;

         - the length of time between customer order to activation of service on
           the digital mobile network, which currently is much longer than that
           of some of its competitors; and

                                       15
<PAGE>   17

         - Nextel's ability to improve the efficiency and speed of the processes
           for Nextel's customer service and accounts receivable collection
           functions.

         Customer reliance on Nextel's customer service functions may increase
      as Nextel adds digital mobile network customers through indirect
      distribution channels and through direct sales channels not involving
      direct face-to-face contact with a sales representative, for example,
      phone order sales or sales through web sites. Nextel's inability to timely
      and efficiently meet the demands for its services could decrease or
      postpone subscriber growth, or delay or otherwise impede billing and
      collection of amounts owed, which would adversely affect Nextel, and could
      adversely affect Nextel's ability to pay cash interest, and to make
      scheduled principal repayments, on its indebtedness, including the notes.

     - IF COMPETITORS PROVIDE TWO-WAY RADIO DISPATCH SERVICES, NEXTEL WILL LOSE
       A COMPETITIVE ADVANTAGE. Nextel's two-way radio dispatch services are
       currently not available through traditional cellular or personal
       communication services providers; however, if either personal
       communication services or cellular operators provide two-way radio
       dispatch or comparable services in the future, Nextel's competitive
       advantage may be impaired.

     Nextel cannot predict the competitive effect that any of these factors, or
any combination of these factors, will have on it or whether it will compete
successfully in the future.

     4. REGULATORY AND OTHER FACTORS COULD DELAY OR PREVENT NEXTEL FROM OFFERING
        SERVICES IN NEW MARKET AREAS, WHICH MAY ADVERSELY AFFECT NEXTEL'S
        ABILITY TO PAY INTEREST AND TO MAKE PRINCIPAL PAYMENTS ON THE NOTES.

     Before fully implementing Nextel's digital mobile network in a new market
area or expanding coverage in an existing market area, Nextel must complete
systems design work, find appropriate sites and construct necessary transmission
structures, receive regulatory approvals, free up frequency channels now devoted
to non-digital transmissions and begin systems optimization. These processes
take weeks or months to complete, and may be hindered or delayed by many
factors, including unavailability of antenna sites at optimal locations, land
use and zoning controversies and limitations of available frequencies. Nextel
cannot know when, if ever, its digital technology will be available for
commercial use in new markets.

     5. NEXTEL RELIES ON MOTOROLA FOR SUBSTANTIALLY ALL OF ITS EQUIPMENT AND
        TECHNOLOGY AND ANY FAILURE OF MOTOROLA TO PERFORM WOULD ADVERSELY AFFECT
        NEXTEL'S OPERATING RESULTS AND NEXTEL'S ABILITY TO PAY INTEREST AND TO
        MAKE PRINCIPAL PAYMENTS ON THE NOTES.

     There is a risk that the failure by Motorola to deliver necessary
technology improvements and enhancements and system infrastructure and
subscriber equipment on a timely, cost-effective basis would have an adverse
effect on Nextel's growth and operations and would adversely affect Nextel's
ability to pay interest and to make principal payments on the notes. Motorola is
currently Nextel's sole source for the infrastructure and subscriber handset
equipment used by Nextel throughout its markets. Nextel expects to rely
principally on Motorola for the manufacture of a substantial portion of the
equipment necessary to construct its digital mobile network and handset
equipment for the next several years. If Motorola does not provide the necessary
equipment to Nextel, then Nextel may not be able to service its existing
subscribers or add new subscribers. Nextel expects that for the next few years,
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 network. Recently, Nextel and Kyocera Corporation of Japan
entered into a memorandum of understanding with the intent to have Kyocera
manufacture a handset compatible with Nextel's digital mobile network. It is
anticipated that Motorola will license its technology to Kyocera to enable
Kyocera to manufacture those handsets. However, Nextel cannot predict when or
whether Kyocera and Motorola will enter into an appropriate license agreement or
that Nextel and Kyocera will be able to negotiate a mutually acceptable
definitive agreement for Kyocera's manufacture and Nextel's purchase of those
handsets.

                                       16
<PAGE>   18

     6. AGREEMENTS WITH MOTOROLA REDUCE NEXTEL'S OPERATIONAL FLEXIBILITY AND MAY
        ADVERSELY AFFECT ITS GROWTH, OR OPERATING RESULTS, WHICH WOULD ADVERSELY
        AFFECT NEXTEL'S ABILITY TO PAY INTEREST AND TO MAKE PRINCIPAL PAYMENTS
        ON THE NOTES.

     Nextel's agreements with Motorola impose limitations and conditions on
Nextel's ability to use other technologies. These terms may operate to delay or
prevent Nextel from employing new or different technologies that perform better
or are available at a lower cost because of the additional economic costs and
other impediments to change arising under the Motorola agreements. For example,
Nextel's equipment purchase agreement with Motorola provides that Nextel must
provide Motorola with notice of its determination that Motorola's technology is
no longer suited to Nextel's needs at least six months before publicly
announcing or entering into a contract to purchase an alternate technology.

     In addition, if Motorola manufactures, or elects to manufacture, the
alternate technology that Nextel elects to deploy, Nextel must give Motorola the
opportunity to supply 50% of its infrastructure requirements for the alternate
technology for three years. Finally, if after a switch to an alternate
technology Nextel does not maintain operational Motorola infrastructure
equipment at the majority of its cell sites that are deployed at the date the
switch to an alternate technology is first publicly announced, Motorola may
require that all financing provided by Motorola to Nextel be repaid.

     7. NEXTEL'S INTERESTS MAY CONFLICT WITH THOSE OF MOTOROLA. ANY CONFLICT
        COULD ADVERSELY AFFECT NEXTEL'S GROWTH, OPERATING RESULTS OR STRATEGIC
        FLEXIBILITY AND NEXTEL'S ABILITY TO PAY INTEREST AND TO MAKE PRINCIPAL
        PAYMENTS ON THE NOTES.

     Motorola and its affiliates engage in wireless communications businesses,
and may in the future engage in additional businesses, which do or may compete
with some or all of the services Nextel offers through its digital mobile
network. Although Nextel believes that its relationship with Motorola reflects
the realities of purchasing from a competitor, Nextel cannot assure you that the
potential conflict of interest will not adversely affect Nextel in the future.
In addition, Motorola is a significant stockholder of Nextel, which creates
potential conflicts of interest, particularly with regard to significant
transactions.

     8. NEXTEL, WHICH OPERATES IN A REGULATED INDUSTRY, MAY BE ADVERSELY
        AFFECTED BY GOVERNMENTAL REGULATION.

     The Federal Communications Commission regulates the licensing, operation,
acquisition and sale of Nextel's specialized mobile radio businesses. Future
changes in regulation or legislation and Congress' and the Federal
Communications Commission's continued allocation of additional commercial mobile
radio services spectrum could impose significant additional costs on Nextel
either in the form of direct out of pocket costs or additional compliance
obligations. These regulations can also have the effect of introducing
additional competitive entrants to the already crowded wireless communications
marketplace.

     Nextel International, Inc.'s operations are subject to similar effects
caused by operating in a regulated industry, since its operations are regulated
by the foreign countries in which its business is conducted and are also subject
to regional and local regulation. Additional information regarding government
regulation can be found in Nextel's Annual Report on Form 10-K for the year
ended December 31, 1998 and Nextel's other filings made under the Securities
Exchange Act of 1934.

     9. NEXTEL HAS SIGNIFICANT INTANGIBLE ASSETS, WHICH MAY NOT BE ADEQUATE TO
        SATISFY ITS OBLIGATIONS IN THE EVENT OF A LIQUIDATION.

     If Nextel defaults on debt or if Nextel were liquidated, Nextel cannot
assure you that the value of its assets will be sufficient to satisfy its
obligations, including its obligations in respect of the notes. Nextel has a
significant amount of intangible assets, such as licenses granted by the Federal
Communications Commission. The value of these licenses will depend significantly
upon the success of Nextel's digital mobile network business and the growth of
the specialized mobile radio and wireless communications industries in general.
Nextel had a net tangible book value deficit of about $2.1 billion as of
September 30, 1999, as adjusted to reflect the receipt of about $2.8 billion in
net proceeds from the public offering of Nextel's common stock, which was
completed on November 5, 1999.

                                       17
<PAGE>   19

     10. NEXTEL IS SUSCEPTIBLE TO CONTROL BY SIGNIFICANT STOCKHOLDERS.

     Significant blocks of Nextel's outstanding stock are held by Motorola and
entities controlled by Mr. Craig O. McCaw. In addition, an affiliate of Mr.
McCaw may designate at least one fourth of the board of directors of Nextel and
may select, from their representatives on the board of directors, a majority of
the operations committee of Nextel's board of directors, which has significant
authority relating to Nextel's business strategy, budgets, financing
arrangements and in the nomination and oversight of specified executive
officers. As a result, Mr. McCaw may exert significant influence over Nextel's
affairs. Presently, three of the ten members of Nextel's board of directors are
designees of Mr. McCaw's affiliates. In addition, Daniel F. Akerson, formerly an
executive officer of Nextel, currently holds positions with Eagle River, Inc.
and NEXTLINK Communications, Inc., each of which is controlled by Mr. McCaw. Mr.
Akerson continues to serve as chairman of Nextel's board of directors and as a
member of the operations committee of the board, but he is not a designee of Mr.
McCaw's affiliates. Under its agreements with Nextel, Motorola may nominate two
directors to the board of directors of Nextel. In addition, Motorola has agreed
to support the decisions and recommendations of the operations committee and to
vote its shares of common stock accordingly, subject to specified limitations.

     If Mr. McCaw and Motorola choose to act together, they could have a
sufficient number of members on Nextel's board of directors and voting interest
in Nextel to, among other things:

     - exert effective control over the approval of amendments to Nextel's
       certificate of incorporation, mergers, sales of assets or other major
       corporate transactions as well as other matters submitted for stockholder
       vote;

     - defeat a takeover attempt; and

     - otherwise control whether particular matters are submitted for a vote of
       the stockholders of Nextel.

     Mr. McCaw and his affiliates have and, subject to the terms of applicable
agreements, may acquire an investment or other interest in entities that provide
wireless telecommunications services that could potentially compete with Nextel.
Under the relevant agreements, Mr. McCaw and his controlled affiliates may not,
for a period of time, participate in other two-way terrestrial-based mobile
wireless communications systems in the region that includes any part of North
America or South America unless these opportunities have first been presented to
and waived or rejected by Nextel.

     11. CONCERNS ABOUT HEALTH RISKS RELATING TO THE USE OF PORTABLE HANDSETS
         MAY AFFECT NEXTEL'S PROSPECTS AND NEXTEL'S ABILITY TO PAY INTEREST AND
         TO MAKE PRINCIPAL PAYMENTS ON THE NOTES.

     Portable communications devices have been alleged to pose health risks due
to radio frequency emissions from these devices. Studies performed by wireless
telephone equipment manufacturers have investigated these allegations, and a
major industry trade association and governmental agencies have stated publicly
that the use of these phones poses no undue health risk. The actual or perceived
risk of portable 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.

     12. IF NEXTEL'S OPERATIONS ARE DISRUPTED DUE TO YEAR 2000 READINESS ISSUES,
         THERE WOULD BE AN ADVERSE EFFECT ON ITS GROWTH AND OPERATING RESULTS
         AND ON NEXTEL'S ABILITY TO PAY INTEREST AND TO MAKE PRINCIPAL PAYMENTS
         ON THE NOTES.

     Nextel may be subject to risks associated with Year 2000 readiness,
including those associated with third parties. Nextel has not yet finally
determined its need for, or, if and where likely to be needed, finally
developed, contingency plans for resolving issues that may be identified and for
which remediation is not possible on a timely or cost-effective basis. If any of
these third parties, or Nextel, is unable to resolve material Year 2000
readiness issues on a timely or cost-effective basis, there would be an adverse
effect on Nextel, and on Nextel's ability to pay interest and to make principal
payments on the notes.

                                       18
<PAGE>   20

     13. RISKS RELATING TO NEXTEL'S JOINT INVESTMENTS MAY ADVERSELY AFFECT
         NEXTEL'S GROWTH AND OPERATING RESULTS AND NEXTEL'S ABILITY TO PAY
         INTEREST AND TO MAKE PRINCIPAL PAYMENTS ON THE NOTES.

     Nextel has entered into a contractual joint venture regarding its ownership
interests in and arrangements with Nextel Partners, Inc., and may enter into
other joint ventures or similar arrangements in the future. Outside the United
States, several of Nextel's international operations are conducted through
entities having one or more third-party owners, and some of these entities are
not controlled by Nextel. There are risks in participating in arrangements of
these types, including the risk that the other participants may at any time have
economic, business or legal interests or goals that are inconsistent with those
of the joint enterprise or Nextel. There also is the risk that a participant may
be unable to meet its economic or other obligations to the joint enterprise and
that Nextel may be required to fulfill some or all of those obligations. Nextel
also may be or become obligated to acquire all or a portion of the ownership
interest of some or all of the other participants in these joint enterprises. In
addition, to the extent that Nextel participates in international arrangements
of these types, the operations of the relevant entity will be subject to various
additional risks not present in domestic joint enterprises.

     14. RISKS RELATING TO NEXTEL'S FOREIGN OPERATIONS MAY ADVERSELY AFFECT
         NEXTEL'S GROWTH AND OPERATING RESULTS AND NEXTEL'S ABILITY TO PAY
         INTEREST AND TO MAKE PRINCIPAL PAYMENTS ON THE NOTES.

     Nextel owns interests in and operates international wireless companies
through Nextel International, Inc. The risks that relate to these foreign
operations include:

     - political, economic and social conditions in the foreign countries where
       Nextel conducts operations;

     - currency risks and exchange controls;

     - potential inflation in the applicable foreign economies;

     - the impact of import duties on the cost or prices of infrastructure
       equipment and subscriber handsets;

     - foreign taxation of earnings and payments received by Nextel
       International, Inc. from its operating subsidiaries;

     - regulatory changes affecting the telecommunications industry and wireless
       communications; and

     - operations being disrupted due to Year 2000 readiness issues affecting
       Nextel International, Inc.

     Nextel cannot assure you that the risks associated with its foreign
operations will not adversely affect its or Nextel International, Inc.'s
operating results or prospects, particularly as these operations expand in
scope, scale and significance.

  B.  RISK FACTORS RELATING TO THE NOTES

     1. NEXTEL MAY BE UNABLE TO PAY INTEREST OR REPAY THE NOTES.

               A. NEXTEL IS A HOLDING COMPANY AND ITS SUBSIDIARIES HAVE NO
                  OBLIGATIONS TO THE HOLDERS OF THE NOTES.

     Nextel conducts substantially all of its business through its subsidiaries.
Nextel's cash flow and, consequently, its ability to pay interest in cash and to
service its debt, including the notes, are dependent upon the cash flow of its
subsidiaries and the payment of funds by those subsidiaries in the form of
loans, dividends or otherwise. Nextel's subsidiaries are separate and distinct
legal entities and will have no obligation, contingent or otherwise, to pay any
amounts due on the notes or to make cash available for that purpose.

                                       19
<PAGE>   21

               B. NEXTEL'S SUBSIDIARIES HAVE RESTRICTIONS ON WHAT THEY CAN PAY
                  TO NEXTEL.

     Nextel and its subsidiaries have entered into financing agreements that
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 its subsidiaries that operate the digital mobile
network in Nextel's market areas in the United States. Similarly, financing
arrangements and indentures entered and to be entered into by Nextel
International, Inc. and the entities in which Nextel International, Inc. holds
investments contain and are expected to impose restrictions on dividends, loans,
advances and other payments to Nextel by Nextel International, Inc. and its
subsidiaries. As long as these limitations are in place, money generated by
these subsidiaries may not be available to Nextel for the payment of interest on
the notes or to repay the notes. If Nextel's financing arrangements limit its
ability to pay interest on the notes when required, Nextel will need to
refinance amounts outstanding under those arrangements to make interest
payments. Nextel cannot assure you that it will be able to refinance this debt.
The failure of Nextel to pay interest on the notes when required could result in
defaults under some of Nextel's debt agreements. Nextel may enter into financing
arrangements in the future that could impose additional restrictions on
dividends, loans, advances and other payments by its subsidiaries. Some of
Nextel's existing financing arrangements contain restrictive covenants
applicable to Nextel and some of its subsidiaries, including a limitation on the
amount of debt that Nextel may incur that may limit its ability to borrow funds
to pay any amounts due pursuant to the notes. Finally, some of these agreements
also contain limitations on some "restricted payments," which could represent
amounts Nextel would need to receive to meet its cash interest and debt service
obligations, including those relating to the notes.

     2. THE SUCCESSFUL IMPLEMENTATION OF NEXTEL'S STRATEGY IS NECESSARY FOR
        NEXTEL TO MEET ITS DEBT SERVICE REQUIREMENTS.

     The successful implementation of Nextel's strategy, including the
continuing build-out, expansion and enhancement of its digital mobile network,
obtaining and retaining a significant number of subscribers and increasing
market share and achieving significant growth in revenues and earnings, is
necessary for Nextel to be able to meet its working capital, capital expenditure
and debt service requirements.

     3. THE LIABILITIES OF NEXTEL'S SUBSIDIARIES AND UNDER NEXTEL'S SECURED DEBT
        ARE EFFECTIVELY SENIOR TO THE NOTES.

     As of September 30, 1999, Nextel's subsidiaries had outstanding
indebtedness and current liabilities of about $4.7 billion, including trade
payables. Assets of some of Nextel's operating subsidiaries secure some of its
senior borrowings. Borrowings by Nextel International, Inc. or its subsidiaries
or affiliates under any bank or vendor financing agreements that may be entered
into from time to time likewise may be secured by liens on assets of Nextel
International, Inc. or of those subsidiaries and affiliates and also may be
guaranteed by those entities as well.

     Nextel and its subsidiaries may incur additional debt, subject to
limitations, and that additional debt may be secured. Secured debt of Nextel and
debt of its subsidiaries will be effectively senior to the notes. Nextel's
subsidiaries have no obligation to pay amounts due on the notes. These
subsidiaries may use the earnings they generate, as well as their existing
assets, to fulfill their own direct debt service requirements, particularly
because the agreements relating to their debt may restrict their ability to pay
dividends or to make loans, advances or other distributions to Nextel or because
the debt of these subsidiaries may be secured by their assets.

     4. NEXTEL'S HIGH LEVEL OF INDEBTEDNESS COULD ADVERSELY AFFECT ITS ABILITY
        TO REPAY THE NOTES.

     At September 30, 1999, Nextel had about $8.4 billion of long term debt,
including the current portion. Furthermore, subject to restrictions in the
indenture for the notes and in its other financing agreements, Nextel, along
with its subsidiaries, may incur additional indebtedness from time to time to
finance further deployment of its digital mobile network, provide for working
capital or capital expenditures or for other purposes. Nextel anticipates that
it and its subsidiaries will incur substantial additional indebtedness in the
future in connection with the further build-out, expansion and enhancement of
its

                                       20
<PAGE>   22

digital mobile network and funding cash flow deficits, including principally
additional borrowings under the terms of the bank financing agreements.

     Nextel's high level of indebtedness could have important consequences to
holders of the notes, including, but not limited to, the following:

     - limiting Nextel's ability to obtain additional financing for
       acquisitions, working capital, capital expenditures or other purposes;

     - limiting Nextel's ability to use operating cash flow in other areas of
       its business because it must dedicate a substantial portion of these
       funds to make cash interest payments and fund required principal payments
       on its debt;

     - limiting Nextel's ability to borrow additional funds or to dispose of
       assets;

     - limiting Nextel's ability to compete with others in its industry who are
       not as highly leveraged; and

     - limiting Nextel's ability to react to changing market conditions, changes
       in its industry and economic downturns.

     5. IF NEXTEL IS UNABLE TO REFINANCE ITS EXISTING INDEBTEDNESS, THERE COULD
        BE AN ADVERSE EFFECT ON NEXTEL'S ABILITY TO PAY INTEREST AND TO MAKE
        PRINCIPAL REPAYMENTS ON THE NOTES.

     Nextel currently has substantial debt obligations that will mature before
the maturity of the notes. In addition, Nextel has preferred stock that it is
required to redeem before the maturity of the notes. Nextel has begun payment of
cash interest on some of its public notes and also must begin to pay cash
interest on some other outstanding debt and cash dividends on some outstanding
shares of preferred stock before the maturity of the notes. Nextel may not be
able to generate sufficient funds from operations to repay all of those
obligations as they are currently scheduled to become due. Accordingly, it will
be necessary to refinance some of those obligations at or before their
respective maturities or mandatory redemption dates. In addition, if Nextel is
prohibited under the terms of any of its debt from paying dividends on its
preferred stock, Nextel will have to refinance that debt or, to the extent
permitted under the terms of its debt, refinance the preferred stock before the
time the dividends would need to be paid. Nextel's ability to refinance these
obligations will depend on, among other factors, its financial condition at the
time of the refinancing, the restrictions contained in its remaining financing
agreements and market conditions. Nextel cannot assure you that it will be able
to refinance those obligations. If Nextel is unable to refinance those
obligations, or unable to obtain satisfactory terms, there could be an adverse
effect on Nextel, including on Nextel's ability to pay cash interest, and to
make scheduled principal repayments on its indebtedness, including the notes.
This risk compounds the risks associated with Nextel's need for additional
financing in order to maintain its growth.

     6. THE INDENTURE CONTAINS RESTRICTIVE DEBT COVENANTS THAT COULD IMPEDE
        NEXTEL IN OBTAINING NECESSARY FINANCING.

     The indenture governing the notes limits what Nextel, and most of its
subsidiaries, may do. The provisions of the indenture limit Nextel's ability to:

     - incur more debt;

     - pay dividends or make distributions of stock other than in or in respect
       of Nextel's preferred stock;

     - issue stock of subsidiaries;

     - make investments or payments;

     - enter into specified transactions with affiliates;

     - merge or consolidate; and

     - transfer and sell substantial assets.

                                       21
<PAGE>   23

     Although there are a number of important exceptions to these covenants,
which are more fully described under "VI. The Exchange Notes," these limitations
could adversely affect Nextel's flexibility.

     Nextel's existing financing agreements contain many similar limitations.
Under specific circumstances, all amounts borrowed under its financing
agreements, plus interest, may be declared to be due and payable, which would be
an event of default under the indenture governing the notes. Nextel cannot
assure you that it would have sufficient assets to pay indebtedness then
outstanding under its other financing agreements and the indenture governing the
notes.

     7. NEXTEL MAY BE UNABLE TO REPURCHASE YOUR NOTES UPON A CHANGE OF CONTROL.

     If Nextel experiences a "Change of Control" as defined in the indenture, it
must offer to purchase the notes at 101% of their face amount, plus accrued
interest. A Change of Control may also trigger similar repurchase obligations
under some of Nextel's other financing arrangements. Nextel may not be able to
pay you the required price for notes you present to it at the time of a Change
of Control, because Nextel might not have enough funds at that time or the terms
of its other financing agreements may prevent it from making those payments.

     8. THERE IS NO PUBLIC MARKET FOR THE EXCHANGE NOTES.

     There is no existing trading market for the outstanding notes. Nextel
cannot assure you that any trading market for the exchange notes will develop.
If such a market were to develop, the outstanding notes and the exchange notes
could trade at prices that may be lower than the initial offering price of the
notes depending on many factors, including prevailing interest rates, Nextel's
operating results and the market for similar securities.

     9. IF YOU DO NOT EXCHANGE YOUR OUTSTANDING NOTES YOU MAY HAVE DIFFICULTY IN
        TRANSFERRING THEM AT A LATER TIME.

     Nextel will issue exchange notes in exchange for the outstanding notes
after the exchange agent receives your outstanding notes, the letter of
transmittal and all related documents before the expiration of the exchange
offer. You should allow adequate time for delivery if you choose to tender your
outstanding notes for exchange. Outstanding notes that are not exchanged will
remain subject to restrictions on transfer and will not have any rights to
registration.

     If you do participate in the exchange offer for the purpose of
participating in the distribution of the exchange notes, you must comply with
the registration and prospectus delivery requirements of the Securities Act of
1933 for any resale transaction. Each broker-dealer who holds outstanding notes
for its own account due to market-making or other trading activities and who
receives exchange notes for its own account must acknowledge that it will
deliver a prospectus in connection with any resale of the exchange notes. If any
outstanding notes are not tendered in the exchange or are tendered but not
accepted, the trading market for such outstanding notes could be negatively
affected due to the limited number of outstanding notes expected to remain
outstanding following the completion of the exchange offer.

  C.  NEXTEL'S FORWARD LOOKING STATEMENTS ARE SUBJECT TO A VARIETY OF FACTORS
      THAT COULD CAUSE ACTUAL RESULTS TO DIFFER MATERIALLY FROM CURRENT BELIEFS.

     "Safe Harbor" Statement under the Private Securities Litigation Reform Act
of 1995: A number of the statements made or incorporated by reference in this
prospectus are not historical or current facts, but deal with potential future
circumstances and developments. Those statements are qualified by the inherent
risks and uncertainties surrounding expectations generally, and also may
materially differ from Nextel's actual experience involving any one or more of
these matters and subject areas. Nextel has attempted to identify, in context,
some 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

                                       22
<PAGE>   24

other risks and uncertainties in addition to the relevant qualifying factors
identified elsewhere in the above "Risk Factors" section and elsewhere in this
prospectus, 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, Nextel's digital mobile network performance;

     - the continued successful performance of the technology being deployed in
       Nextel's various market areas;

     - the ability to achieve and maintain market penetration and average
       subscriber revenue levels sufficient to provide financial viability to
       Nextel's digital mobile network business;

     - Nextel's ability to timely and successfully accomplish required scale-up
       of its billing, collection, customer care and similar back-room
       operations to keep pace with customer growth, increased system usage
       rates and growth in levels of accounts receivables being generated by the
       digital mobile network customer base;

     - 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 personal communication services;

     - the ability to successfully develop or obtain from third parties, and
       implement, Year 2000 readiness solutions in systems that are critical to
       Nextel's business operations;

     - future legislation or regulatory actions relating to specialized mobile
       radio services, other wireless communications services or
       telecommunications generally; and

     - other risks and uncertainties described from time to time in Nextel's
       reports and, with specific reference to risk factors relating to
       international operations, in Nextel International, Inc.'s reports, filed
       with the Securities and Exchange Commission, including the Annual Reports
       on Form 10-K for the fiscal year ended December 31, 1998 and the
       Quarterly Reports on Form 10-Q for the quarters ended March 31, 1999,
       June 30, 1999 and September 30, 1999 of Nextel and Nextel International,
       Inc.

IV.  USE OF PROCEEDS

     Nextel will not receive any cash proceeds from the issuance of the exchange
notes. Because Nextel is exchanging the exchange notes for the outstanding
notes, which have substantially identical terms, the issuance of the exchange
notes will not result in any increase in the indebtedness of Nextel.

V.  THE EXCHANGE OFFER

  A.  PURPOSE AND EFFECT OF THE EXCHANGE OFFER

     On November 12, 1999, Nextel sold $2.0 billion in principal amount of the
outstanding notes in a private placement through Goldman, Sachs & Co., as
representative of the initial purchasers, to a limited number of "Qualified
Institutional Buyers," as defined under the Securities Act of 1933, and to a
limited number of persons outside the United States. In connection with the sale
of the outstanding notes, Nextel and Goldman, Sachs & Co., as representative of
the initial purchasers, entered into a registration rights agreement, dated as
of November 12, 1999. Under that agreement, Nextel must, among other things, use
its best efforts to file with the Commission a registration statement under the
Securities Act of 1933 covering the exchange offer and to cause that
registration statement to become effective under the

                                       23
<PAGE>   25

Securities Act of 1933. Upon the effectiveness of that registration statement,
Nextel must also offer each holder of the outstanding notes the opportunity to
exchange its outstanding notes for an equal principal amount of exchange notes.
You are a holder with respect to the exchange offer if you are a person in whose
name any outstanding notes are registered on Nextel's books or if you have
obtained a properly completed assignment of outstanding notes from the
registered holder.

     Nextel is making the exchange offer to comply with its obligations under
the registration rights agreement. A copy of the registration rights agreement
has been filed as an exhibit, by incorporation by reference, to the registration
statement of which this prospectus is a part.

     In order to participate in the exchange offer, you must represent to
Nextel, among other things, that:

     - the exchange notes being acquired pursuant to the exchange offer are
       being obtained in the ordinary course of business of the person receiving
       the exchange notes,

     - neither you nor any other person is engaging in or intends to engage in a
       distribution of those exchange notes,

     - neither you nor any other person has an arrangement or understanding with
       any third person to participate in the distribution of the exchange
       notes, and

     - neither you nor any other person is an affiliate of Nextel. An affiliate
       is any person who "controls or is controlled by or is under common
       control with" Nextel.

  B.  RESALE OF THE EXCHANGE 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), Morgan Stanley & Co. Incorporated
(available June 5, 1991), Mary Kay Cosmetics, Inc. (available June 5, 1991),
Warnaco, Inc. (available October 11, 1991), and K-III Communications Corp.
(available May 14, 1993), Nextel believes that the exchange notes issued in the
exchange offer may be offered for resale, resold, and otherwise transferred by
you, except if you are an affiliate of Nextel, without compliance with the
registration and prospectus delivery provisions of the Securities Act of 1933,
provided that the representations set forth above in "-- Purpose and Effect of
the Exchange Offer" apply to you.

     If you tender in the exchange offer with the intention of participating in
a distribution of the exchange notes, you cannot rely on the interpretation by
the Staff of the Commission as set forth in the Morgan Stanley & Co.
Incorporated no-action letter and other similar letters and you must comply with
the registration and prospectus delivery requirements of the Securities Act of
1933 in connection with a secondary resale transaction. In the event that
Nextel's belief regarding resale is inaccurate, those who transfer exchange
notes in violation of the prospectus delivery provisions of the Securities Act
of 1933 and without an exemption from registration under the federal securities
laws may incur liability under these laws. Nextel does not assume or indemnify
you against this liability.

     The exchange offer is not being made to, nor will Nextel accept surrenders
for exchange from, holders of outstanding 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 the particular jurisdiction. Each broker-dealer
that receives exchange notes for its own account in exchange for outstanding
notes, where the outstanding notes were acquired by that broker-dealer as a
result of market-making activities or other trading activities, must acknowledge
that it will deliver a prospectus in connection with any resale of the exchange
notes by that broker-dealer. In order to facilitate the disposition of exchange
notes by broker-dealers participating in the exchange offer, Nextel has agreed,
subject to specific conditions, to make this prospectus, as it may be amended or
supplemented from time to time, available for delivery by those broker-dealers
to satisfy their prospectus delivery obligations under the Securities Act of
1933.

     Nextel is obligated to deal with only one entity representing the
broker-dealers participating in the exchange offer, which is Goldman, Sachs &
Co. unless it elects not to act as the representative of the broker-dealers. Any
holder that is a broker-dealer participating in the exchange offer must notify
Goldman,
                                       24
<PAGE>   26

Sachs & Co. at the telephone number set forth in the enclosed Letter of
Transmittal and must comply with the procedures for brokers-dealers
participating in the exchange offer. Among other things, Goldman, Sachs & Co. is
required to confirm with Nextel on a weekly basis that the prospectus is
available. In addition, broker-dealers participating in the exchange offer will
be required to confirm this availability with Goldman, Sachs & Co. on a weekly
basis. Under the registration rights agreement, Nextel is not required to amend
or supplement the prospectus for a period exceeding 90 days after the expiration
date of the exchange offer, except in limited circumstances where Nextel
suspends use of the registration statement. Nextel has not entered into any
arrangement or understanding with any person to distribute the exchange notes to
be received in the exchange offer. See "VIII. Plan of Distribution."

  C.  TERMS OF THE EXCHANGE OFFER

     Upon the terms and subject to the conditions set forth in this prospectus
and in the Letter of Transmittal, Nextel will accept any and all outstanding
notes validly tendered and not withdrawn prior to 5:00 p.m., New York City time,
on the day the exchange offer expires.

     As of the date of this prospectus, $2.0 billion in principal amount of the
notes are outstanding. This prospectus, together with the Letter of Transmittal,
is being sent to all registered holders of the outstanding notes on this date.
There will be no fixed record date for determining registered holders of the
outstanding notes entitled to participate in the exchange offer; however,
holders of the outstanding notes must tender their certificates therefor or
cause their outstanding notes to be tendered by book-entry transfer prior to the
expiration date of the exchange offer to participate.

     The form and terms of the exchange notes will be the same as the form and
terms of the outstanding notes except that the exchange notes will be registered
under the Securities Act of 1933 and therefore will not bear legends restricting
their transfer. Following consummation of the exchange offer, all rights under
the registration rights agreement accorded to holders of outstanding notes,
including the right to receive additional incremental interest on the
outstanding notes, to the extent and in the circumstances specified in the
registration rights agreement, will terminate.

     Nextel intends to conduct the exchange offer in accordance with the
provisions of the registration rights agreement and applicable federal
securities laws. Outstanding notes that are not tendered for exchange under the
exchange offer will remain outstanding and will be entitled to the rights under
the related indenture. Any outstanding notes not tendered for exchange will not
retain any rights under the registration rights agreement and will remain
subject to transfer restrictions. See "-- Consequences of Failure to Exchange."

     Nextel will be deemed to have accepted validly tendered outstanding notes
when, as and if Nextel will have given oral or written notice of its acceptance
to the exchange agent. The exchange agent will act as agent for the tendering
holders for the purposes of receiving the exchange notes from Nextel. If any
tendered outstanding notes are not accepted for exchange because of an invalid
tender, the occurrence of other events set forth in this prospectus, or
otherwise, certificates for any unaccepted outstanding notes will be returned,
or, in the case of outstanding notes tendered by book-entry transfer, those
unaccepted outstanding notes will be credited to an account maintained with The
Depository Trust Company, without expense to the tendering holder of those
outstanding notes as promptly as practicable after the expiration date of the
exchange offer. See "-- Procedures for Tendering."

     Those who tender outstanding 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. Nextel will pay all charges and expenses, other than
applicable taxes described below, in connection with the exchange offer. See
"-- Fees and Expenses."

  D.  EXPIRATION DATE; EXTENSIONS; AMENDMENTS


     The expiration date is 5:00 p.m., New York City time on February 10, 2000,
unless Nextel, in its sole discretion, extends the exchange offer, in which
case, the expiration date will be the latest date and


                                       25
<PAGE>   27

time to which the exchange offer is extended. Nextel may, in its sole
discretion, extend the expiration date of, or terminate, the exchange offer.

     To extend the exchange offer, Nextel must notify the exchange agent 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 make a public
announcement of the extension.

     Nextel reserves the right:

     - to delay accepting any outstanding notes, to extend the exchange offer or
       to terminate the exchange offer if any of the conditions set forth below
       under "-- Conditions" are not satisfied, by giving oral or written notice
       of the delay, extension, or termination to the exchange agent; or

     - to amend the terms of the exchange offer in any manner consistent with
       the registration rights agreement.

     Any delay in acceptances, extension, termination, or amendment will be
followed as promptly as practicable by oral or written notice of the delay to
the registered holders of the outstanding notes. If Nextel amends the exchange
offer in a manner that constitutes a material change, Nextel will promptly
disclose the amendment by means of a prospectus supplement that will be
distributed to the registered holders of the outstanding notes, and Nextel 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 of the outstanding notes, if the exchange offer would
otherwise expire during the five to ten business day period following that
amendment and its disclosure.

     Without limiting the manner in which Nextel may choose to make a public
announcement of any delay, extension, amendment, or termination of the exchange
offer, Nextel will have no obligation to publish, advertise, or otherwise
communicate that 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,
Nextel will accept, promptly after the expiration date of the exchange offer,
all outstanding notes properly tendered and will issue the exchange notes
promptly after acceptance of the outstanding notes. See "-- Conditions" below.
For purposes of the exchange offer, Nextel will be deemed to have accepted
properly tendered outstanding notes for exchange when, as and if Nextel will
have given oral or written notice of its acceptance to the exchange agent.

     In all cases, issuance of the exchange notes for outstanding 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 those outstanding notes
or a timely confirmation of book-entry transfer of the outstanding notes into
the exchange agent's account at The Depository Trust Company, a properly
completed and duly executed Letter of Transmittal, and all other required
documents; provided, however, that Nextel reserves the absolute right to waive
any defects or irregularities in the tender of outstanding notes or in the
satisfaction of conditions of the exchange offer by holders of the outstanding
notes. If any tendered outstanding notes are not accepted for any reason set
forth in the terms and conditions of the exchange offer, if the holder withdraws
such previously tendered outstanding notes, or if outstanding notes are
submitted for a greater principal amount of outstanding notes than the holder
desires to exchange, then the unaccepted, withdrawn or portion of non-exchanged
outstanding notes, as appropriate, will be returned as promptly as practicable
after the expiration or termination of the exchange offer, or, in the case of
outstanding notes tendered by book-entry transfer, those unaccepted, withdrawn
or portion of non-exchanged outstanding notes, as appropriate, will be credited
to an account maintained with The Depository Trust Company, without expense to
the tendering holder thereof.

                                       26
<PAGE>   28

  E.  CONDITIONS

     Without regard to other terms of the exchange offer, Nextel will not be
required to exchange any exchange notes for any outstanding notes and may
terminate the exchange offer before the acceptance of any outstanding notes for
exchange, if:

     - 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 Nextel's reasonable judgment, might materially impair the
       ability of Nextel to proceed with the exchange offer;

     - the Staff of the Commission proposes, adopts or enacts any law, statute,
       rule or regulation or issues any interpretation of any existing law,
       statute, rule or regulation, which, in Nextel's reasonable judgment,
       might materially impair the ability of Nextel to proceed with the
       exchange offer; or

     - any governmental approval or approval by holders of the outstanding notes
       has not been obtained, which approval Nextel will, in its reasonable
       judgment, deem necessary for the consummation of the exchange offer.

     If Nextel determines that any of these conditions are not satisfied, Nextel
may

     - refuse to accept any outstanding notes and return all tendered
       outstanding notes to the tendering holders, or, in the case of
       outstanding notes tendered by book-entry transfer, credit those
       outstanding notes to an account maintained with The Depository Trust
       Company,

     - extend the exchange offer and retain all outstanding notes tendered prior
       to the expiration of the exchange offer, subject, however, to the rights
       of holders who tendered the outstanding notes to withdraw their tendered
       outstanding notes, or

     - subject to applicable law, waive unsatisfied conditions with respect to
       the exchange offer and accept all properly tendered outstanding notes
       that have not been withdrawn. If the waiver constitutes a material change
       to the exchange offer, Nextel will promptly disclose the waiver by means
       of a prospectus supplement that will be distributed to the registered
       holders of the outstanding notes, and Nextel 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 of the outstanding notes, if the exchange offer would otherwise
       expire during this period following such waiver and its disclosure.

  F.  PROCEDURES FOR TENDERING

     To tender in the exchange offer, you must complete, sign and date an
original or facsimile Letter of Transmittal, have the signatures thereon
guaranteed if required by the Letter of Transmittal, and mail or otherwise
deliver the Letter of Transmittal to the exchange agent for receipt before the
expiration date of the exchange offer. In addition, either:

     - certificates for the outstanding notes must be received by the exchange
       agent, along with the Letter of Transmittal, or

     - a timely confirmation of transfer by book-entry of those outstanding
       notes, if the book-entry procedure is available, into the exchange
       agent's account at The Depository Trust Company, as set forth in the
       procedure for book-entry transfer described below, which the exchange
       agent must receive prior to the expiration date of the exchange offer, or

     - you must comply with the guaranteed delivery procedures described below.

     To be tendered effectively, the exchange agent must receive the Letter of
Transmittal and other required documents at the address set forth below under
"-- Exchange Agent" prior to the expiration of the exchange offer.

                                       27
<PAGE>   29

     If you tender your outstanding notes and do not withdraw them prior to the
expiration date of the exchange offer, you will be deemed to have an agreement
with Nextel in accordance with the terms and subject to the conditions set forth
in this prospectus and in the Letter of Transmittal.

     THE METHOD OF DELIVERY OF OUTSTANDING NOTES AND THE LETTER OF TRANSMITTAL
AND ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT YOUR RISK. INSTEAD
OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT YOU 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 OF
THE EXCHANGE OFFER. NO LETTER OF TRANSMITTAL OR OUTSTANDING NOTES SHOULD BE SENT
TO NEXTEL. YOU MAY REQUEST YOUR RESPECTIVE BROKERS, DEALERS, COMMERCIAL BANKS,
TRUST COMPANIES, OR NOMINEES TO EFFECT THE ABOVE TRANSACTIONS FOR YOU.

     Any beneficial owner whose outstanding notes are registered in the name of
a broker, dealer, commercial bank, trust company, or other nominee and who
wishes to tender its outstanding notes should contact the registered holder
promptly and instruct that registered holder to tender the outstanding notes on
the beneficial owner's behalf. If the beneficial owner wishes to tender its
outstanding notes on the owner's own behalf, that owner must, prior to
completing and executing the Letter of Transmittal and delivering its
outstanding notes, either make appropriate arrangements to register ownership of
the outstanding notes in that owner's name or obtain a properly completed
assignment from the registered holder. The transfer of registered ownership of
outstanding 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 unless the
outstanding notes tendered pursuant thereto are tendered:

     - by a registered holder who has not completed the box entitled "Special
       Payment Instructions" or "Special Delivery Instructions" on the Letter of
       Transmittal; or

     - 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, each of the
following is deemed an eligible institution:

     - a member firm of a registered national securities exchange or of the
       National Association of Securities Dealers, Inc.,

     - a commercial bank,

     - a trust company having an office or correspondent in the United States or

     - an eligible guarantor institution as provided by Rule 17Ad-15 of the
       Securities Exchange Act of 1934.

     If the Letter of Transmittal is signed by a person other than the
registered holder of any outstanding notes, the outstanding notes must be
endorsed or accompanied by a properly completed bond power, signed by the
registered holder as his, her or its name appears on the outstanding notes.

     If trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity sign the Letter of Transmittal or any outstanding notes or bond power,
those persons should so indicate when signing, and evidence satisfactory to
Nextel of their authority to so act must be submitted with the Letter of
Transmittal, unless Nextel waives that requirement.

     Nextel will determine all questions as to the validity, form, eligibility,
including time of receipt, acceptance of tendered outstanding notes, and
withdrawal of tendered outstanding notes, in its sole discretion. All of these
determinations by Nextel will be final and binding. Nextel reserves the absolute
right to reject any and all outstanding notes not properly tendered or any
outstanding notes Nextel's acceptance of which would, in the opinion of counsel
for Nextel, be unlawful. Nextel also reserves the right to waive any defects,
irregularities or conditions of tender as to particular outstanding notes.
Nextel'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

                                       28
<PAGE>   30

connection with tenders of outstanding notes must be cured within the time
Nextel determines. Although Nextel intends to notify holders of outstanding
notes of defects or irregularities with respect to tenders of outstanding notes,
neither Nextel, nor the exchange agent, or any other person will incur any
liability for failure to give this notification. Tenders of outstanding notes
will not be deemed to have been made until defects or irregularities have been
cured or waived. Any outstanding 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 outstanding notes, unless otherwise provided in the Letter of
Transmittal, as soon as practicable following the expiration date of the
exchange offer.

     In addition, Nextel reserves the right, in its sole discretion, to purchase
or make offers for any outstanding notes that remain outstanding subsequent to
the expiration date of the exchange offer 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 outstanding notes in the open market, in privately
negotiated transactions or otherwise. The terms of any purchases or offers could
differ from the terms of the exchange offer.

     If the holder of outstanding notes is a broker-dealer participating in the
exchange offer that will receive exchange notes for its own account in exchange
for outstanding notes that were acquired as a result of market-making activities
or other trading activities, that broker-dealer will be required to acknowledge
in the Letter of Transmittal that it will deliver a prospectus in connection
with any resale of the exchange notes and otherwise agree to comply with the
procedures described above under "-- Resale of the Exchange Notes"; however, by
so acknowledging and delivering a prospectus, that broker-dealer will not be
deemed to admit that it is an "underwriter" within the meaning of the Securities
Act of 1933.

     In all cases, issuance of exchange notes pursuant to the exchange offer
will be made only after timely receipt by the exchange agent of certificates for
the outstanding notes or a timely confirmation of book-entry transfer of
outstanding notes into the exchange agent's account at The Depository Trust
Company, a properly completed and duly executed Letter of Transmittal, and all
other required documents. If any tendered outstanding notes are not accepted for
any reason set forth in the terms and conditions of the exchange offer or if
outstanding notes are submitted for a greater principal amount of outstanding
notes than the holder of outstanding notes desires to exchange, the unaccepted
or portion of non-exchanged outstanding notes will be returned as promptly as
practicable after the expiration or termination of the exchange offer, or, in
the case of outstanding notes tendered by book-entry transfer into the exchange
agent's account at The Depository Trust Company pursuant to the book-entry
transfer procedures described below, the unaccepted or portion of non-exchanged
outstanding notes will be credited to an account maintained with The Depository
Trust Company, without expense to the tendering holder of outstanding notes.

  G.  BOOK-ENTRY TRANSFER


     The exchange agent will make a request to establish an account with respect
to the outstanding notes at The Depository Trust Company 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 The Depository Trust
Company's systems may make book-entry delivery of outstanding notes by causing
The Depository Trust Company to transfer the outstanding notes into the exchange
agent's account at The Depository Trust Company in accordance with The
Depository Trust Company's procedures for transfer. However, although delivery
of outstanding notes may be effected through book-entry transfer at The
Depository Trust Company, the Letter of Transmittal or a manually signed
facsimile thereof, with any required signature guarantees or an Agent's Message,
in the case of a book-entry transfer, 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 of
the exchange offer, unless the holder complies with the guaranteed delivery
procedures described below.


                                       29
<PAGE>   31

  H.  GUARANTEED DELIVERY PROCEDURES

     Holders who wish to tender their outstanding notes and (1) whose
outstanding notes are not immediately available or (2) who cannot deliver their
outstanding notes, the Letter of Transmittal, or any other required documents to
the exchange agent prior to the expiration date, may effect a tender if:

     - the tender is made through an eligible institution;


     - before the expiration date of the exchange offer, the exchange agent
       receives from such 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, the
       certificate number(s) of the outstanding notes and the principal amount
       of outstanding notes tendered and stating that the tender is being made
       thereby and guaranteeing that, within three New York Stock Exchange
       trading days after the date of execution of the Notice of Guaranteed
       Delivery, the Letter of Transmittal, together with the certificate(s)
       representing the outstanding notes in proper form for transfer or a
       confirmation of book-entry transfer, 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



     - the exchange agent receives the properly completed and executed Letter of
       Transmittal, as well as the certificate(s) representing all tendered
       outstanding notes in proper form for transfer and other documents
       required by the Letter of Transmittal within three New York Stock
       Exchange trading days after the date of execution of the Notice of
       Guaranteed Delivery.


     Upon request to the exchange agent, a Notice of Guaranteed Delivery will be
sent to holders who wish to tender their outstanding notes according to the
guaranteed delivery procedures set forth above.

  I.  WITHDRAWAL OF TENDERS

     Except as otherwise provided, tenders of outstanding notes may be withdrawn
at any time prior to 5:00 p.m., New York City time, on the expiration date of
the exchange offer.

     To withdraw a tender of outstanding 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 of the exchange offer. Any such notice of withdrawal must

     - specify the name of the person having deposited the outstanding notes to
       be withdrawn,

     - identify the outstanding notes to be withdrawn,

     - be signed by the holder in the same manner as the original signature on
       the Letter of Transmittal by which the outstanding notes were tendered or
       be accompanied by documents of transfer sufficient to have the exchange
       agent register the transfer of the outstanding notes in the name of the
       person withdrawing the tender, and

     - specify the name in which any outstanding notes are to be registered, if
       different from that of the person who deposited the outstanding notes to
       be withdrawn.

     Nextel will determine all questions as to the validity, form, and
eligibility of the notices, which determination will be final and binding on all
parties. Any outstanding notes so withdrawn will be deemed not to have been
validly tendered for purposes of the exchange offer, and no exchange notes will
be issued with respect to those outstanding notes unless the outstanding notes
so withdrawn are validly retendered.

     Any outstanding notes that have been tendered but that are withdrawn or not
accepted for payment will be returned to the holder of those outstanding notes,
or in the case of outstanding notes tendered by book-entry transfer, will be
credited to an account maintained with The Depository Trust Company, without
cost to the holder as soon as practicable after withdrawal, rejection of tender
or termination of the exchange offer. Properly withdrawn outstanding notes may
be retendered by following one of the

                                       30
<PAGE>   32

procedures described above under "-- Procedures for Tendering" at any time
before the expiration date of the exchange offer.

  J.  TERMINATION OF CERTAIN RIGHTS

     All rights given to holders of outstanding notes under the registration
rights agreement will terminate upon the consummation of the exchange offer
except with respect to Nextel'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 of the exchange offer, and

     - to provide copies of the latest version of this prospectus to any
       broker-dealer that requests copies of this prospectus for use in
       connection with any resale by that broker-dealer of exchange notes
       received for its own account pursuant to the exchange offer in exchange
       for outstanding 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 Notes."

  L.  FEES AND EXPENSES

     Nextel will pay the expenses of soliciting tenders in connection with the
exchange offer. 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 Nextel and its affiliates.

     Nextel 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. Nextel, however, will pay the exchange agent
reasonable and customary fees for its services and will reimburse the exchange
agent for its reasonable out-of-pocket expenses in connection with the exchange
offer.

     Nextel estimates that its cash expenses in connection with the exchange
offer will be about $300,000. These expenses include registration fees, fees and
expenses of the exchange agent, accounting and legal fees, and printing costs,
among others.

     Nextel will pay all transfer taxes, if any, applicable to the exchange of
the outstanding notes for exchange notes. The tendering holder of outstanding
notes, however, will pay applicable taxes if certificates representing
outstanding 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 outstanding notes tendered, or

     - if tendered, the certificates representing outstanding notes are
       registered in the name of any person other than the person signing the
       Letter of Transmittal, or

                                       31
<PAGE>   33

     - if a transfer tax is imposed for any reason other than the exchange of
       the outstanding notes in the exchange offer.

     If satisfactory evidence of payment of the transfer taxes or exemption from
payment of transfer taxes is not submitted with the Letter of Transmittal, the
amount of the transfer taxes will be billed directly to the tendering holder and
the exchange notes need not be delivered until the transfer taxes are paid.

  M.  CONSEQUENCES OF FAILURE TO EXCHANGE

     Participation in the exchange offer is voluntary. Holders of the
outstanding notes are urged to consult their financial and tax advisors in
making their own decisions on what action to take.

     Outstanding notes that are not exchanged for the exchange notes in the
exchange offer will not retain any rights under the registration rights
agreement and will remain restricted securities for purposes of the federal
securities laws. Accordingly, the outstanding notes may not be offered, sold,
pledged, or otherwise transferred except:

     - to Nextel or any subsidiary thereof;

     - to a "Qualified Institutional Buyer" within the meaning of Rule 144A
       under the Securities Act of 1933 purchasing for its own account or for
       the account of a qualified institutional buyer in a transaction meeting
       the requirements of Rule 144A;

     - in an offshore transaction complying with Rule 904 of Regulation S under
       the Securities Act of 1933;

     - pursuant to an exemption from registration under the Securities Act of
       1933 provided by Rule 144 thereunder, if available;

     - to "Institutional Accredited Investors" in a transaction exempt from the
       registration requirements of the Securities Act of 1933; or

     - pursuant to an effective registration statement under the Securities Act
       of 1933, and, in each case, in accordance with all other applicable
       securities laws.

  N.  ACCOUNTING TREATMENT

     For accounting purposes, Nextel will recognize no gain or loss as a result
of the exchange offer. The exchange notes will be recorded at the same carrying
value as the outstanding notes, as reflected in Nextel's accounting records on
the date of the exchange. The expenses of the exchange offer will be amortized
over the remaining term of the exchange notes.

VI.  THE EXCHANGE NOTES

     The outstanding notes were, and the exchange notes will be, issued under
the indenture, dated as of November 12, 1999 between Nextel, as issuer, and
Harris Trust and Savings Bank, as trustee. 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. The following summary 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 terms used in the indenture and those
terms made a part of the indenture by reference to the Trust Indenture Act.

  A.  GLOSSARY OF DEFINED TERMS

     Whenever the notes or 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, the calculation will be
made as if the transactions or events occurred on the first day of the period,
unless otherwise specified. All accounting terms not otherwise defined in the
notes or the indenture have the meanings ascribed to them in accordance with
generally accepted accounting principles. Except as otherwise expressly provided
in the notes or the indenture, the term "generally accepted accounting

any specified Person means the power to direct the management and policies of

with that specified Person.

                 of each successive scheduled principal payment of the Debt, and

             (b) the amount of the principal payment,

                 Moody's for a period of at least 90 consecutive days, beginning
                 on the date of the event, which period will be extended up to
                 90 additional days for as long as the rating of those debt
                 securities is under publicly announced consideration for
                 possible downgrading by the applicable rating agency, or

             (b) if the person is a corporation:

                - that is not, and does not have any outstanding debt securities
                  that are, rated by Moody's or any other rating agency of
                  national standing at any time during a period of 90

                  period will be extended up to an additional 90 days for as
                  long as any applicable rating agency has publicly announced
                  that the corporation or debt thereof will be rated, unless
                  after that date, but during that period debt securities of the
                  corporation having a maturity at original issuance of at least
                  one year are rated Investment Grade by S&P or Moody's and

                  that, solely for the purpose of calculating Total Common
                  Equity as of the later Trading Day, the average Closing Price
                  of the common stock of the person will be deemed to equal the

                 Voting Stock or Total Common Equity of the surviving or
                 transferee Person;

             provided that no Change of Control will be deemed to occur under
        this clause (2),

                - if the surviving or transferee Person or the person referred
                  to in clause (2)(b) is a corporation with outstanding debt

                  period will be extended up to 90 additional days for as long
                  as the rating of the debt securities is under publicly
                  announced consideration for possible downgrading by the
                  applicable rating agency, or

                - if the surviving or transferee Person or other person is a

                      rating agency of national standing at any time during a
                      period of 90 consecutive days beginning on the date of
                      that event, which period will be extended up to an
                      additional 90 days for as long as any applicable rating
                      agency has publicly announced that the corporation or debt
                      thereof will be rated, unless after that date, but during
                      the period debt securities of the corporation having a
                      maturity at original issuance of at least one year are
                      rated Investment Grade by S&P or Moody's and remain so
                      rated for the remainder of the period referred to in the
                      clause above, and

                    - that, when determined as of the Trading Day immediately

                      the event, has Total Common Equity of at least $10
                      billion, provided that, solely for the purpose of
                      calculating Total Common Equity as of the later Trading
                      Day, the average Closing Price of the common stock of that
                      person will be deemed to equal the Closing Price of the
                      common stock on the later Trading Day, subject to the last
                      sentence of the definition of "Total Common Equity"; or

     (3) during any consecutive two-year period, individuals who at the
         beginning of that period constituted the board of directors, together
         with any directors who are members of the board of directors on the
         Closing Date and any new directors whose election by that board of
         directors or whose nomination for election by the stockholders of
         Nextel was approved by a vote of 66 2/3% of the directors then still in
         office who were either directors at the beginning of the period or
         whose election or nomination for election was previously so approved,
         cease for any reason to constitute a majority of the board of directors
         then in office.

Any event that would constitute a Change of Control pursuant to clause (1) or
(2) above:

     - but for the proviso thereto will not be deemed to be a Change of Control
       until the time, if any, as the conditions described in that proviso cease
       to have been met, and

     - if and to the extent resulting from any restructuring transaction or any
       sale or assignment of all or substantially all of the assets and
       liabilities of Nextel to, or merger or consolidation of Nextel with,

                                       35
<PAGE>   37

       any Person, any such transaction, a "Restructuring Transaction", effected
       at substantially the same time as and in connection with any of the
       Permitted Transactions described in clause (1) of the definition of the
       term "Permitted Transactions" will not constitute a Change of Control so
       long as the Persons who, immediately prior to the closing of the
       Restructuring Transaction and the particular Permitted Transaction being
       consummated at substantially the same time and in connection therewith,
       the "Restructuring Closing", were the Beneficial Owners, directly or
       indirectly, of more than 50% of the total Voting Stock and more than 50%

       securities in the Restructuring Transaction and related Permitted
       Transaction), the Beneficial Owners, directly or indirectly, of more than
       50% of the total Voting Stock and more than 50% of the Total Common
       Equity of Nextel (or the surviving or transferee Person, as the case may
       be). Immediately after any transaction or combination of transactions
       described in this bulleted point, no Person may be the ultimate
       Beneficial Owner of more than 50% of the total Voting Stock or more than
       50% of the Total Common Equity of Nextel, or the surviving or transferee
       Person, as the case may be, unless the Person was the Beneficial Owner of
       more than 50% of the total Voting Stock and more than 50% of the Total
       Common Equity of Nextel immediately before the transaction or combination
       of transactions.

to trading on any national securities exchange, on the Nasdaq Stock Market or,
if no shares Capital of Stock are listed or admitted to trading on any national
securities exchange or quoted on the Nasdaq Stock Market, but the issuer is a
Foreign Issuer, as defined in Rule 3b-4(b) under the Securities Exchange Act of
1934, and the principal securities exchange on which the shares are listed or

     "ZERO COUPON PREFERRED STOCK" means the Zero Coupon Convertible Preferred
Stock due 2013 of Nextel issued on December 23, 1998.

  B.  GENERAL

     The exchange notes will be general, unsecured obligations of Nextel limited
in aggregate principal amount to $2.0 billion and will mature on November 15,
2009. The exchange notes will be issued in fully registered form only in
denominations and integral multiples of $1,000. The exchange notes will be
senior, unsecured indebtedness of Nextel, will rank equally in right of payment
with all unsubordinated, unsecured indebtedness of Nextel, including, without
limitation, the indebtedness evidenced by the Existing Senior Notes, and will be
senior in right of payment to all subordinated indebtedness of Nextel. The
exchange notes will be effectively subordinated to all current and future
indebtedness of Nextel's subsidiaries, including trade payables and other
accrued liabilities. Substantially all of this subsidiary indebtedness presently
is, and is expected to be, secured by the assets of Nextel's subsidiaries and/or
guaranteed by Nextel and its subsidiaries.

     Principal of, premium, if any, and interest on the notes will be payable,
and the notes may be presented for registration of transfer or exchange, at the
office of the Paying Agent and Registrar. At Nextel's option, interest may be
paid by check mailed to the registered address of holders of the notes as shown
on the register for the notes. The Trustee will initially act as Paying Agent
and Registrar. Nextel may change any Paying Agent and Registrar without prior
notice to holders of the notes. Holders of the notes must surrender notes to the
Paying Agent to collect principal payments.

     Cash interest on the notes will be payable at a rate of 9.375% per year,
semi-annually in arrears on each May 15 and November 15, with the first payment
on May 15, 2000 to holders of record of such notes at the close of business on
the May 1 and November 1 next preceding the interest payment date. Cash interest
will accrue from the most recent interest payment date to which interest has
been paid or duly provided for or, if no interest has been paid or duly provided
for, from the Closing Date. Cash interest will be computed on a basis of a
360-day year of twelve 30-day months. Some of Nextel's existing debt agreements
restrict the ability of Nextel's subsidiaries to pay dividends to enable Nextel
to pay interest on the notes.

     The notes are not subject to any sinking fund.

  C.  OPTIONAL REDEMPTION

     The notes may be redeemed at any time on or after November 15, 2004, at
Nextel's option, in whole or in part, upon not less than 30 or 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 thereof, set forth below, plus
an amount in cash equal to all accrued and unpaid interest to the redemption
date, if redeemed during the twelve-month period beginning November 15 of each
of the years set forth below.

<TABLE>
<CAPTION>
                       YEAR                         PERCENTAGE
                       ----                         ----------
<S>                                                 <C>

2006..............................................   101.563
2007 and thereafter...............................   100.000
</TABLE>

     In addition, in the event of one or more sales by Nextel on or before
November 15, 2002 of at least $50 million of its Capital Stock, other than
Redeemable Stock, Nextel may redeem up to a maximum of 35% of the original
principal amount of the notes at a redemption price equal to 109.375% of their
principal amount plus accrued and unpaid interest to the redemption date;
provided that the redemption occurs within 180 days after consummation of any
such sale of Capital Stock.

                                       50
<PAGE>   52

     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 any other method as the Trustee in its sole
discretion deems 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 those notes will
state the portion of the principal amount of those notes to be redeemed. A new
note in principal amount equal to the unredeemed portion of the notes will be
issued in the name of the holder of the notes upon cancellation of the original
note.

  D.  CHANGE OF CONTROL

     Upon the occurrence of a Change of Control, Nextel will be required to make
an Offer to Purchase to each holder of the notes to repurchase all or any part
of the holder's notes at a cash purchase price equal to 101% of the principal
amount of those notes, plus accrued and unpaid interest to the date of purchase.
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
applicable securities laws.

     None of the provisions in the indenture relating to a purchase upon a
Change of Control are waivable by the board of directors. Nextel could, in the
future, enter into transactions, including recapitalizations of Nextel, that
would not constitute a Change of Control, but would increase the amount of
indebtedness outstanding at that time. If a Change of Control were to occur,
Nextel would be obligated:

     - for a Change of Control occurring on or after December 15, 2005, or any
       earlier refinancing of, or termination of the covenants with respect to,
       all of the Old Senior Notes, the 11 1/2% Senior Redeemable Discount Notes
       due 2003 of Nextel and the 12 1/4% Senior Redeemable Dial Page Discount
       Notes due 2004, to offer to purchase outstanding shares of the Series D
       Preferred Stock and the Series E Preferred Stock,

     - for a Change of Control occurring before December 23, 2005 or any earlier
       refinancing of, or termination of the covenants with respect to, all of
       the Old Senior Notes, to either offer to purchase outstanding shares of
       the Zero Coupon Preferred Stock or increase the conversion rate of the
       Zero Coupon Preferred Stock,

     - for a Change of Control occurring on or after December 23, 2005 or any
       earlier refinancing of, or termination of the covenants with respect to,
       all of the Old Senior Notes, to offer to purchase outstanding shares of
       the Zero Coupon Preferred Stock,

     - to offer to purchase all Debt which then would be entitled to receive a
       comparable offer to purchase by reason of the Change in Control,
       including, without limitation, the Existing Senior Notes, and

     - to offer to repurchase the notes.

     There can be no assurance that Nextel would have sufficient funds to pay
the purchase price for all notes that Nextel would be required to purchase if a
Change of Control were to occur. In the event that Nextel were required to
purchase outstanding notes pursuant to an Offer to Purchase, Nextel 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 Nextel
would be able to obtain the financing. In addition, Nextel's ability to purchase
the notes may be limited by other then-existing agreements.

  E.  CERTAIN COVENANTS

     LIMITATION ON CONSOLIDATED DEBT

     Nextel will not, and will not permit any Restricted Subsidiary to, Incur
any Debt, including Acquired Debt, other than Permitted Debt, unless

     (1) with respect to Debt Incurred under this clause (1), 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 Nextel after June 1, 1997 from the issuance and
         sale, other than a Restricted Subsidiary, of shares of its Capital
         Stock, other than Redeemable Stock, or any options, warrants or other
         rights to purchase the Capital Stock other than Redeemable Stock, other
         than

          (a) proceeds applied for use as a Directed Investment, unless the

              make the Investment pursuant to the "Limitation on Restricted
              Payments" covenant, other than as a Directed Investment, and

          (b) proceeds which have been included in the computation of the
              amounts available for Restricted Payments pursuant to clause 3(b)

              covenant, to the extent the inclusion thereof was necessary to
              allow a subsequent Restricted Payment to be made, or

     (2) on the date of the Incurrence, after giving effect to the Incurrence of
         the Debt or Acquired Debt and the receipt and application of the net
         proceeds thereof, and, if the net proceeds of the new Debt are used to
         acquire a Person that becomes a Restricted Subsidiary or an operating
         business of Nextel or a Restricted Subsidiary, to all terms of the
         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

     Nextel will not, directly or indirectly:

     (1) 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 of the Capital Stock, other than Redeemable Stock;

     (2) purchase, redeem or otherwise acquire or retire for value, or permit
         any Restricted Subsidiary to, directly or indirectly, purchase, redeem

         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

     (4) 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 the Investment;

                                       52
<PAGE>   54

     (each of the foregoing actions set forth in clauses (1) through (4), other
than an action that is a Permitted Investment or a Permitted Distribution, is a
"Restricted Payment") unless, at the time of the Restricted Payment, and after
giving effect thereto:

     (1) no Default or Event of Default will have occurred and be continuing;

     (2) except with respect to Investments, after giving effect, on a pro forma
         basis, to the Restricted Payment and the Incurrence of any Debt the net

              the last day of the last fiscal quarter preceding the date of the
              proposed Restricted Payment, plus

          (b) 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 Nextel from the issuance and
              sale, other than to a Restricted Subsidiary, on or after February
              15, 1994 of shares of its Capital Stock, except for Redeemable
              Stock, or any options, warrants or other rights to purchase that
              Capital Stock, except for Redeemable Stock, other than

               clause (4) 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

             - 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

                - to make a Directed Investment, unless the designation has been
                  revoked by the board of directors and Nextel is able to make

                  Payments" covenant, other than as a Directed Investment or

                - to Incur Debt under clause (1) of the "Limitation on
                  Consolidated Debt" covenant, unless and until the amount of
                  the Debt

                    - is treated as newly issued Debt and could be Incurred in
                      accordance with the "Limitation on Consolidated Debt"
                      covenant, other than under clause (1) thereof, or

                    - has been repaid or refinanced with the proceeds of Debt
                      Incurred in accordance with the "Limitation on
                      Consolidated Debt" covenant, other than under clause (1)
                      thereof, or

                    - has otherwise been repaid, plus

          (c) 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 will be conclusive and evidenced by
              a Board Resolution, received by Nextel from the issuance or sale,
              other than to a Restricted Subsidiary, after February 15, 1994 of
              any Capital Stock of Nextel, other than Redeemable Stock, or any
              options, warrants or other rights to purchase Capital Stock, other

                                       53
<PAGE>   55

          than Redeemable Stock, upon the conversion of, or exchange for, Debt
          of Nextel 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 will be counted as a
Restricted Payment for purposes of clause (3) in the preceding paragraph. In
addition, the foregoing limitations do not prevent Nextel from

     (1) paying a dividend on Capital Stock of Nextel within 60 days after the
         declaration thereof if, on the date when the dividend was declared,
         Nextel could have paid the dividend in accordance with the provisions
         of the indenture,

     (2) repurchasing Capital Stock of Nextel, including options, warrants or
         other rights to acquire the Capital Stock from employees or former
         employees of Nextel or any Subsidiary thereof for consideration not to
         exceed $500,000 in the aggregate in any fiscal year, with repurchases
         pursuant to this clause (2) not being counted as Restricted Payments
         for purposes of clause (3) in the preceding paragraph, or

     (3) the repurchase, redemption or other acquisition for value of Capital
         Stock of Nextel to the extent necessary to prevent the loss or secure
         the renewal or reinstatement of any license or franchise held by Nextel
         or any of its Subsidiaries from any governmental agency; or

     (4) Investments in Unrestricted Subsidiary Funding Company so long as

          (a) the Investments are invested in Nextel International, Inc. and

          (b) Nextel International, Inc. is a Subsidiary of Nextel.

     Notwithstanding the foregoing limitations in this "Limitation on Restricted
Payments" covenant, Nextel will be permitted to make any Investment in a Person
that is not, either before or after giving effect thereto, a Subsidiary of
Nextel, provided that, immediately after giving effect thereto, the amount equal
to

     (1) the aggregate amount of all Investments made pursuant to this paragraph
         minus

     (2) all cash received by Nextel or any Restricted Subsidiary from the sale,
         transfer or other disposition to a Person that is not a Subsidiary of
         Nextel, of any Investment, or portion thereof, included in the
         aggregate amount, with the amount of cash to be counted for this
         purpose not to exceed the amount of the Investment, or portion thereof,
         so included,

     will not exceed the greater of

          (a) $250 million and

          (b) 2% of the Total Market Value of Equity of Nextel as of the time.

For purposes of determining the aggregate amount of Investments referred to in
clause (1), the amount of any Investment will be deemed to equal the cash
portion thereof plus the fair market value of any non-cash portion thereof, to
the extent the portion constitutes an Investment, at the time the Investment is
made, as determined by the board of directors, whose good faith determination
will 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 Investments previously made in the Person shall no longer be
counted as Restricted Payments for purposes of calculating the aggregate amount
of Restricted Payments pursuant to clause (3) of the third preceding paragraph
or the aggregate amount of Investments pursuant to clause (1) of the immediately
preceding paragraph, in each case to the extent the Investments would otherwise
be so

                                       54
<PAGE>   56

counted. For purposes of clause (3)(c) above, the net proceeds received by
Nextel from the issuance or sale of its Capital Stock either upon the conversion
of, or exchange for, Debt of Nextel or any Restricted Subsidiary will be deemed
to be an amount equal to

     (1) the sum of

          (a) the principal amount or accreted value, whichever is less, of Debt
              on the date of the conversion or exchange and

          (b) the additional cash consideration, if any, received by Nextel upon
              the conversion or exchange, less any payment on account of
              fractional shares, minus

     (2) all expenses incurred in connection with the issuance or sale.

     In addition, for purposes of clause (3)(c) above, the net proceeds received
by Nextel from the issuance or sale of its Capital Stock upon the exercise of
any options or warrants of Nextel or any Restricted Subsidiary will be deemed to
be an amount equal to

     (1) the additional cash consideration, if any, received by Nextel upon the
         exercise, minus

     (2) all expenses incurred in connection with the issuance or sale.

     For purposes of this "Limitation on Restricted Payments" covenant, if a
particular Restricted Payment involves a non-cash payment, including a
distribution of assets, then the Restricted Payment will be deemed to be an
amount equal to the cash portion of the Restricted Payment, if any, plus an
amount equal to the fair market value of the non-cash portion of the Restricted
Payment, as determined by the board of directors, whose good faith determination
will be conclusive and evidenced by a Board Resolution.

     RESTRICTED SUBSIDIARIES

     Nextel will not designate any Restricted Subsidiary as an Unrestricted
Subsidiary, and will not itself, and will 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 the transaction, unless, after
giving effect to any 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 the transaction, and business of Nextel and
its remaining Restricted Subsidiaries generated at least 90% of Digital
Mobile-SMR Operating Cash Flow in the fiscal quarter of Nextel most recently
completed prior to the date of the action.

     The board of directors may designate any existing Unrestricted Subsidiary
or any Person that is about to become a Subsidiary of Nextel as a Restricted
Subsidiary if, after giving effect to the action (and, if the designation is
made in connection with the acquisition of a Person or an operating business
that is about to become a Subsidiary of Nextel, after giving effect to all terms
of the acquisition) on a pro forma basis, on the date of the action, the Debt,
if any, of the Unrestricted Subsidiary or Person outstanding immediately prior
to the designation would have been permitted to be Incurred, and will 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 will, for all purposes of the "Limitation on Restricted
Payments" covenant, including the second clause (2) thereof, be deemed to be a
Restricted Payment of an amount equal to the fair market value of Nextel's
ownership interest in the Subsidiary, including, without duplication, such
indirect ownership interest in all Subsidiaries of the Subsidiary, as determined
by the board of directors in good faith and evidenced by a Board Resolution.

                                       55
<PAGE>   57

     Notwithstanding the foregoing provisions of this "Restricted Subsidiaries"
covenant, the board of directors may not designate a Subsidiary of Nextel to be
an Unrestricted Subsidiary if, after that designation,

     (1) Nextel or any of its other Restricted Subsidiaries

          (a) provides credit support for, or a Guarantee of, any Debt of the
              Subsidiary, including any undertaking, agreement or instrument
              evidencing the Debt, or

          (b) is directly or indirectly liable for any Debt of the Subsidiary,

     (2) a default with respect to any Debt of the Subsidiary, including any
         right which the holders thereof may have to take enforcement action
         against the Subsidiary, would permit, upon notice, lapse of time or
         both, any holder of any other Debt of Nextel or any Restricted
         Subsidiary to declare a default on the other Debt or cause the payment
         thereof to be accelerated or payable prior to its final scheduled
         maturity or

     (3) the 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 Nextel as an Unrestricted Subsidiary, and may
designate any newly-created Subsidiary as an Unrestricted Subsidiary, if at the
time that Subsidiary is created it contains no assets, other than the de minimis
amount of assets then required by law for the formation of corporations, and no
Debt. Subsidiaries of Nextel that are not designated by the board of directors
as Restricted or Unrestricted Subsidiaries will 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 may not change the designation of a
Subsidiary of Nextel more than twice in any period of five years.

     TRANSACTIONS WITH AFFILIATES

     Nextel will not, and will 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 Nextel on terms that are less
favorable to Nextel or such Restricted Subsidiary, as the case may be, than
those that might be obtained at the time of the transaction from a Person that
is not an Affiliate; provided, however, that this "Transactions with Affiliates"
covenant will not limit, or be applicable to,

     (1) any transaction involving one or more Unrestricted Subsidiaries and not
         involving Nextel or any Restricted Subsidiary,

     (2) any transaction between Nextel and any Restricted Subsidiary or between
         Restricted Subsidiaries or

     (3) any Permitted Transactions.

     In addition, any transaction or series of related transactions, other than
Permitted Transactions, between Nextel or any Restricted Subsidiary and any
Affiliate of Nextel, other than a Restricted Subsidiary, involving an aggregate
consideration of $5 million or more must be approved in good faith by a majority
of Nextel'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
Nextel or any Restricted Subsidiary and an Affiliate of Nextel that is approved
by a majority of the Disinterested Directors, of which there must be at least
one, and evidenced by a Board Resolution will be deemed to be on terms as
favorable as those that might be obtained at the time of the transaction, or
series of transactions, from a Person that is not an Affiliate and thus will be
permitted under this covenant.

     ACTIVITIES OF NEXTEL AND RESTRICTED SUBSIDIARIES

     Nextel will not, and will not permit any Restricted Subsidiary to, engage
in any business other than the telecommunications business and related
activities and services, including those businesses, activities and services as
Nextel and the Restricted Subsidiaries were engaged in on the Closing Date.

     PROVISION OF FINANCIAL INFORMATION

     Regardless of whether Nextel is subject to Section 13(a) or 15(d) of the
Securities Exchange Act of 1934, or any successor provision, Nextel will file
with the Commission the annual reports, quarterly reports and other documents
which Nextel would have been required to file with the Commission pursuant to
Section 13(a) or 15(d) or any successor provision thereto if Nextel were subject
thereto, the documents to be filed with the Commission on or prior to the
respective dates by which Nextel would have been required to file them. Nextel
will also in any event:

     (1) 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 those holders,
              and

          (b) file with the Trustee

        copies of the annual reports, quarterly reports and other documents
        which Nextel 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 Nextel were subject thereto and

     (2) if filing the documents by Nextel with the Commission is not permitted
         under the Securities Exchange Act of 1934, promptly upon written
         request supply copies of the documents to any prospective holder.

     The Trustee's receipt of the reports, information and documents will not
constitute constructive notice of any information contained in or determinable
from information in the applicable report or document.

     MERGER, SALE OF ASSETS, ETC.

     Nextel

     (1) will 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

     (2) will not permit any of its Restricted Subsidiaries to enter into any
         transaction or series of transactions if the 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 Nextel and its Restricted Subsidiaries, taken as a whole,
         substantially as an entirety to any Person,

unless, in each case (1) or (2), at the time and after giving effect thereto

          (a) either:

             - if the transaction or series of transactions is a consolidation
               of Nextel with or a merger of Nextel with or into any other
               Person, Nextel is the surviving Person of the merger or
               consolidation, or

             - the Person formed by any consolidation with or merger with or
               into Nextel, or to which the properties and assets of Nextel or
               Nextel 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 surviving Person
               or transferee Person referred to in this clause being the
               "Surviving Entity") must be a corporation, partnership or trust
               organized and existing under the laws of the United States, any
               state or the District of Columbia

                                       57
<PAGE>   59

             and must expressly assume by a supplemental indenture executed and
             delivered to the Trustee, in form satisfactory to the Trustee, all
             the obligations of Nextel under the notes and the indenture and, in
             each case, the indenture, as so supplemented, will remain in full
             force and effect, and

          (b) immediately before and immediately after giving effect to the
              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 the transaction or series of
              transactions), no Default or Event of Default may have occurred
              and be continuing, and

          (c) the Consolidated Net Worth of Nextel or the Surviving Entity, as
              the case may be, will be equal to or greater than that of Nextel
              immediately prior to the transaction or series of transactions;

        provided, however, that the foregoing requirements will 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,
Nextel will deliver, or cause to be delivered, to the Trustee, in form and
substance reasonably satisfactory to the Trustee, an Officers' Certificate
stating that the consolidation, merger, sale, assignment, conveyance, transfer,
lease or other disposition and the supplemental indenture in respect thereof,
required under second bullet point under clause (a) 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 Officers'
Certificate will set forth the manner of determination of the Consolidated Net
Worth in accordance with clause (c) 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 the 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 Nextel and its Subsidiaries immediately prior
to the transaction or series of transactions will be deemed to have been
Incurred upon the transaction or series of transactions.

  F.  EVENTS OF DEFAULT

     The following will be Events of Default under the indenture:

     (1) failure to pay principal of, or premium, if any, on, any notes when
         due;

     (2) failure to pay any interest on any notes when due, continued for 30
         days;

     (3) default in the payment of principal of, and premium and interest, if
         any, on the 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;

     (4) failure to perform or comply with the provisions described under
         "Merger, Sale of Assets, Etc.";

     (5) failure to perform any other covenant or agreement of Nextel under the
         indenture or the notes continued for 60 days after written notice to
         Nextel by the Trustee or holders of at least 25% in aggregate principal
         amount of outstanding notes;

     (6) failure to pay when due (subject to any applicable grace period) the
         principal of, or acceleration of, any Debt of Nextel or any Restricted
         Subsidiary having an outstanding principal amount of at least $25.0
         million, individually or in the aggregate;

                                       58
<PAGE>   60

     (7) the rendering of a final judgment or judgments against Nextel or any
         Restricted Subsidiary in an amount in excess of $25.0 million which
         remains undischarged or unstayed for a period of 60 days after the date
         on which the right to appeal has expired; and

     (8) specified events of bankruptcy, insolvency or reorganization affecting
         Nextel or any Restricted Subsidiary.

     If an Event of Default (other than an Event of Default described in clause
(8) above) occurs and is 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 principal amount of all the notes; provided however
that after the acceleration, but before a judgment or decree based on
acceleration, the holders by Required Consent may, under some circumstances,
rescind and annul the acceleration if all Events of Default, other than the
nonpayment of the principal amount of the notes, have been cured or waived as
provided in the indenture. If an Event of Default specified in clause (8) above
occurs, the principal amount of the outstanding notes will automatically 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, if an Event of Default occurs and is 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 the holders shall have
offered to the Trustee reasonable security or indemnity. Subject to the
provisions for the indemnification of the Trustee, the holders by Required
Consent 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

     - the holder has previously given to the Trustee written notice of a
       continuing Event of Default,

     - the holders of at least 25% in aggregate principal amount at Stated
       Maturity of the Outstanding Securities have made written request to the
       Trustee to institute the proceeding as trustee,

     - the holder or holders have offered reasonable indemnity to the Trustee
       for expenses of the proceeding,

     - the Trustee failed to institute the proceeding within 60 days after
       receiving the request, and

     - the Trustee has not received from the holders of a majority in aggregate
       principal amount at Stated Maturity of the Outstanding Securities a
       direction inconsistent with the request.

However, those 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 the note on or after the respective due dates set forth in the note.

     Nextel will be required to furnish to the Trustee annually a statement as
to the performance by it of some of its obligations under the indenture and as
to any default in the performance.

  G.  DEFEASANCE AND COVENANT DEFEASANCE

     Nextel 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 some restrictive covenants in the indenture, applied
to the Outstanding Securities, as a whole and not in part.

                                       59
<PAGE>   61

     Defeasance and Discharge.  Upon Nextel's exercise of its option to have the
provisions relating to defeasance and discharge applied to the Outstanding
Securities, Nextel will be discharged from all its obligations with respect to
the notes, except for obligations to:

        - exchange or register the transfer of the notes,

        - replace stolen, lost or mutilated notes,

        - maintain paying agencies and

        - hold moneys for payment in trust,

upon the deposit in trust for the benefit of the holders of the notes of money
or United States 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 the notes on the respective Stated Maturities thereof
in accordance with the terms of the indenture and the notes. This defeasance or
discharge may occur only if, among other things, Nextel has delivered to the
Trustee an opinion of counsel to the effect that Nextel 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 the notes will not recognize gain or loss for federal income tax purposes as
a result of the 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.  Upon Nextel's exercise of its option to
defease the restrictive covenants applied to the Outstanding Securities, Nextel
may omit to comply with specified restrictive covenants, including those
described under "Covenants" and clause (2)(c) under "Merger, Sale of Assets,
Etc.," and the occurrence of specified Events of Default, which are described
above in clause (4), with respect to clause (2)(c)), clause (5), with respect to
the restrictive covenants, clause (6) and clause (7) under "Events of Default,"
will be deemed not to be or result in an Event of Default, in each case with
respect to the notes. Nextel, in order to exercise the option, will be required
to deposit, in trust for the benefit of the holders of the 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 the notes on the respective Stated Maturities thereof in accordance with the
terms of the indenture and the notes. Nextel will also be required, among other
things, to deliver to the Trustee an opinion of counsel to the effect that
holders of the notes will not recognize gain or loss for federal income tax
purposes as a result of the deposit and defeasance of some 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 the deposit and defeasance were
not to occur.

     In the event Nextel exercised this option with respect to the Outstanding
Securities and these 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 Nextel, the amount of money and United
States Government Obligations so deposited in trust would be sufficient to pay
amounts due on the notes at the time of their respective Stated Maturities but
may not be sufficient to pay amounts due on the notes upon the acceleration or
redemption. In this case, Nextel would remain liable for the payments.

  H.  MODIFICATION AND WAIVER

     Modifications and amendments of the indenture may be made by Nextel and the
Trustee with Required Consent; provided, however, that no such modification or
amendment may, without the consent of each holder of the notes affected thereby:

     (1) change the Stated Maturity of the principal of, or any installment of
         interest on, any note,

     (2) reduce the principal amount of, premium, if any, or interest on, any
         note,

                                       60
<PAGE>   62

     (3) change the place or currency of payment of principal or premium, if
         any, or interest on, any note,

     (4) 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,

     (5) reduce the above-stated percentage of Outstanding Securities the
         consent of whose holders is necessary to modify or amend the indenture,

     (6) waive a default in the payment of principal of, premium, if any, or
         interest on, the notes,

     (7) reduce the percentage of aggregate principal amount of Outstanding
         Securities the consent of whose holders is necessary for waiver of
         compliance with provisions of the indenture or for waiver of defaults
         or

     (8) following the mailing of an Offer to Purchase, modify the provisions of
         the indenture with respect to the Offer to Purchase in a manner adverse
         to those holders.

  I.  NO PERSONAL LIABILITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS, DIRECTORS
      OR EMPLOYEES

     There will be no recourse against any incorporator or past, present or
future stockholder, officer, director, employee or controlling person of Nextel

        - for the payment of the principal of, premium, if any, or interest on,
          any of the notes, or

        - for any claim and no recourse under or upon any obligation, covenant
          or agreement of Nextel contained in the indenture or in any of the
          notes, or

        - because of the creation of any Debt represented thereby.

     Each holder, by accepting the notes, waives and releases all the liability.

  J.  CONCERNING THE TRUSTEE

     Except during the continuance of an Event of Default, the Trustee will
perform only those 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 the indenture and use the same degree of
care and skill in its exercise of these rights and powers as a prudent person
would exercise under the circumstances in the conduct of the 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
should it become a creditor of Nextel, to obtain payment of claims in some cases
or to realize on property received by it in respect of any 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 the conflict or resign.

  K.  BOOK ENTRY; DELIVERY AND FORM

     The exchange notes will initially be issued in the form of one global
certificate. The global exchange note will be deposited on the date of the
consummation of the exchange offer with or on behalf of The Depository Trust
Company and registered in the name of The Depository Trust Company or its
nominee.

     Nextel understands that The Depository Trust Company 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 Securities Exchange Act of 1934. The Depository
Trust Company 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 other organizations. Indirect access to The
                                       61
<PAGE>   63

Depository Trust Company system is available to other banks, brokers, dealers
and trust companies that clear through or maintain a custodial relationship with
a participant, either directly or indirectly.

     So long as The Depository Trust Company, or its nominee, is the registered
owner or holder of the global exchange note, The Depository Trust Company or the
nominee, as the case may be, will be considered the sole owner or holder of the
exchange notes represented by the global exchange note for all purposes under
the indenture. No beneficial owner of an interest in a global exchange note will
be able to transfer that interest except in accordance with The Depository Trust
Company's applicable procedures, in addition to those provided for under the
indenture.

     Payments made with respect to a global exchange note will be made to The
Depository Trust Company or its nominee, as the case may be, as the registered
owner thereof. Nextel will have no responsibility or liability for any aspect of
the records relating to or payments made on account of beneficial ownership
interests in a global exchange note or for maintaining, supervising or reviewing
any records relating to such beneficial ownership interests.

     Nextel expects that The Depository Trust Company or its nominee, upon
receipt of any payments made with respect to a global exchange note, will credit
participants' accounts with payments in amounts proportionate to their
respective beneficial interests in the principal amount of such global exchange
note as shown on the records of The Depository Trust Company or its nominee.
Nextel also expects that payments by participants to owners of beneficial
interests in such global exchange 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. These payments will be the responsibility of the
participants.

     Transfers between participants in The Depository Trust Company will be
effected in the ordinary way in accordance with The Depository Trust Company
rules and will be settled in same-day funds.

     Although The Depository Trust Company is expected to follow the foregoing
procedures in order to facilitate transfers of interests in the global exchange
note among participants of The Depository Trust Company, it is under no
obligation to perform or continue to perform such procedures, and such
procedures may be discontinued at any time. Nextel will have no responsibility
for the performance by The Depository Trust Company or its respective
participants or indirect participants of its respective obligations under the
rules and procedures governing their operations.

  L.  CERTIFICATED NOTES

     If The Depository Trust Company is at any time unwilling or unable to
continue as a depositary for the global exchange note and a successor depositary
is not appointed by Nextel within 90 days, Nextel will issue a physical
certificate for such notes in exchange for the global exchange note. In
addition, if there is an Event of Default under the notes, The Depository Trust
Company may exchange the global exchange note for certificated notes and
distribute these certificated notes to its participants. Finally, beneficial
owners whose interests are represented by the global exchange note may request a
physical certificate.

VII.  PRINCIPAL UNITED STATES FEDERAL TAX CONSIDERATIONS TO NON-U.S. HOLDERS

     The following is a summary of specified United States federal income and
estate tax matters. In the case of Non-U.S. Holders, as defined below, this
discussion summarizes the principal United States Federal income tax
considerations of the exchange offer and of the purchase, ownership and
disposition of the notes. In the case of U.S. Holders, as defined below, this
discussion addresses only the United States federal income tax consequences of
the exchange offer. This summary is based on the Internal Revenue Code of 1986,
existing and proposed Treasury regulations promulgated under that Code, and
administrative and judicial interpretations of the regulations, all as of the
date of this prospectus and all of which are subject to change, possibly with
retroactive effect.

     This summary deals only with notes held as capital assets within the
meaning of Section 1221 of the Code. It does not discuss all of the tax
considerations that may be relevant to holders of the notes in light
                                       62
<PAGE>   64

of their particular circumstances or to holders of the notes subject to special
rules, for example, banks, insurance companies, tax-exempt organizations,
dealers in securities or foreign currencies, persons holding the notes as part
of a hedging transaction, "straddle," conversion transaction, or other
integrated transaction, or foreign currency effects on holders of the notes
whose functional currency, as defined in Section 985 of the Code, is not the
United States dollar. Persons considering the purchase of the notes should
consult with their own tax advisors about the application of the United States
federal income tax laws to their particular situations as well as any tax
considerations under the laws of any state, local or foreign jurisdiction.

     As used in this prospectus, the term "U.S. Holder" means a beneficial owner
of notes that is, for United States federal income tax purposes:

     - a citizen or individual resident of the United States;

     - a corporation, or other entity treated as a corporation, created in or
       under the laws of the United States or of any state;

     - an estate the income of which is subject to United States federal income
       taxation regardless of its source;

     - a trust over which a court within the United States is able to exercise
       primary supervision over the administration of the trust and one or more
       United States persons have the authority to control all substantial
       decisions of the trust, including certain trusts in existence on August
       20, 1996 and treated as United States persons prior to this date that
       timely elected to continue to be treated as United States persons; or

     - a partnership, or other entity treated as a partnership, created or
       organized in or under the laws of the United States or of any state,
       except as Treasury regulations may provide.

     The term "Non-U.S. Holder" means any holder that is not a U.S. Holder.

EXCHANGE OFFER

     The exchange of the outstanding notes for exchange notes should not be
treated as a taxable transaction to U.S. Holders or to Non-U.S. Holders for
United States federal income tax purposes. Rather, the exchange notes received
should be treated as a continuation of the outstanding notes surrendered in
exchange. As a result, there should be no material United States federal income
tax consequences to U.S. Holders or to Non-U.S. Holders exchanging outstanding
notes for exchange notes.

OWNERSHIP AND DISPOSITION OF NOTES BY NON-U.S. HOLDERS

     Under present United States federal law, and subject to the discussion
below concerning backup withholding:

          (a) payments of principal, interest and premium, if any, on the notes
              by Nextel or its paying agent to any Non-U.S. Holder will not be
              subject to 30% United States federal withholding tax, provided
              that, in the case of interest,

           - the holder does not own, actually or constructively, 10% or more of
             the total combined voting power of all classes of stock of Nextel
             entitled to vote and is not a controlled foreign corporation
             related, directly or indirectly, to Nextel through stock ownership,
             and

           - the certification requirement set forth in Section 871(h) or
             Section 881(c) of the Code has been fulfilled with respect to the
             beneficial owner, as discussed below;

          (b) a Non-U.S. Holder of a note will not be subject to United States
              federal income tax on gain realized on the sale, exchange or other
              disposition of that note, unless

           - the Non-U.S. Holder is an individual who is present in the United
             States for 183 days or more in the taxable year of the disposition
             and specific other conditions are met, or
                                       63
<PAGE>   65

           - the gain is effectively connected with the conduct by this Non-U.S.
             Holder of a trade or business in the United States; and

          (c) under Code Section 2105(b) with respect to United Stated federal
              estate tax law, a note held by an individual who is not, for
              United States estate tax purposes, a citizen or resident of the
              United States at the time of his death generally will not be
              subject to United States federal estate tax as a result of that
              individual's death, provided that the individual does not own,
              actually or constructively, 10% or more of the total combined
              voting power of all classes of stock of Nextel entitled to vote
              and, at the time of that individual's death, payments with respect
              to the note would not have been effectively connected with the
              conduct by that individual of a trade or business in the United
              States.


     The certification requirement referred to in the second bullet point of
paragraph (a) will be fulfilled if the beneficial owner of a note certifies on a
properly executed Internal Revenue Service ("IRS") Form W-8, IRS Form W-8BEN or
successor form under penalties of perjury, that it is not a United States person
and provides its name and address, and


           - that beneficial owner files IRS Form W-8, IRS Form W-8BEN or
             successor form with the withholding agent or

           - in the case of a note held by a securities clearing organization,
             bank or other financial institution holding customers' securities
             in the ordinary course of its trade or business holding the note on
             behalf of the beneficial owner, that financial institution files
             with the withholding agent a statement that it has received the IRS
             Form W-8, IRS Form W-8BEN or successor form from the holder and
             furnishes the withholding agent with a copy thereof. With respect
             to notes held by a foreign partnership, under current law, the IRS
             Form W-8 may be provided by the foreign partnership. However, for
             interest and disposition proceeds paid with respect to a note after
             December 31, 2000, unless the foreign partnership has entered into
             a withholding agreement with the IRS, a foreign partnership will be
             required, in addition to providing an intermediary IRS Form W-8IMY
             or successor form, to attach an appropriate certification by each
             partner. Prospective investors, including foreign partnerships and
             their partners, should consult their tax advisers regarding
             possible additional reporting requirements.

     If a Non-U.S. Holder is engaged in a trade or business in the United
States, and if interest on the note is effectively connected with the conduct of
such trade or business, the Non-U.S. Holder, although exempt from the
withholding tax discussed in the preceding paragraphs, will generally be subject
to regular United States income tax on interest and on any gain realized on the
sale, exchange or disposition of a note on a net income basis in the same manner
as if it were a United States person. In lieu of the certificate described in
the preceding paragraph, such a holder will be required to provide to the
withholding agent a properly executed IRS Form 4224, IRS Form W-8ECI or
successor form, to claim an exemption from withholding tax. In addition, if such
Non-U.S. Holder is a foreign corporation, it may be subject to a 30% branch
profits tax for the taxable year, subject to adjustments. For purposes of the
branch profits tax, interest or any gain recognized on the sale, exchange or
other disposition of a note will be included in the effectively connected
earnings and profits of the Non-U.S. Holder if such interest or gain, as the
case may be, is effectively connected with the conduct by the Non-U.S. Holder of
a trade or business in the United States.

     BACKUP WITHHOLDING AND INFORMATION REPORTING. Nextel will, where required,
report to Non-U.S. Holders of notes and to the IRS the amount of any interest
paid on the notes. Under current United States federal income tax law, backup
withholding tax of 31% will not apply to payments on a note if the
certifications required by Sections 871(h) and 881(c) of the Code are received,
provided in each case that the payer, including a bank or its paying agent, as
the case may be, does not have actual knowledge that the payee is a United
States person.

                                       64
<PAGE>   66

     Under current Treasury regulations, payments on the sale, exchange or other
disposition of a note made to or through a foreign office of a broker generally
will not be subject to information reporting or backup withholding. However, if
such broker is a United States person, a controlled foreign corporation for
United States federal income tax purposes, a foreign person 50% or more of whose
gross income is effectively connected with a United States trade or business for
a specified three-year period or, in the case of payments made after December
31, 2000, a foreign partnership with specific connections to the United States,
then information reporting will be required unless the broker has in its records
documentary evidence that the beneficial owner otherwise establishes an
exemption. Backup withholding may apply to any payment that the broker is
required to report if the broker has actual knowledge that the payee is a United
States person. Payments to or through the United States office of a broker will
be subject to backup withholding and information reporting unless the holder
certifies, under penalties of perjury, that it is not a United States person or
otherwise establishes an exemption.

     Treasury regulations recently issued by the IRS, which are generally
effective for payments made after December 31, 2000, make certain modifications
to the certification procedures applicable to Non-U.S. Holders. Non-U.S. Holders
of notes should consult their tax advisers regarding the application of
information reporting and backup withholding in their particular situations, the
availability of an exemption therefrom, and the procedure for obtaining that
exemption, if available. Any amounts withheld from a payment to a Non-U.S.
Holder under the backup withholding rules will be allowed as a credit against
the holder's United States federal income tax liability and may entitle the
holder to a refund, provided that the required information is furnished to the
IRS.

VIII.  PLAN OF DISTRIBUTION

     Except as described below, a broker-dealer may not participate in the
exchange offer in connection with a distribution of the exchange notes. Each
broker-dealer that receives exchange notes for its own account pursuant to the
exchange offer must acknowledge that it will deliver a prospectus in connection
with any resale of the exchange notes by such broker-dealer. This prospectus, as
it may be amended or supplemented from time to time, may be used by a
broker-dealer in connection with resales of exchange notes received for its own
account in exchange for outstanding notes where those outstanding notes were
acquired as a result of market-making activities or other trading activities.
Nextel has agreed that for a period of 90 days after the expiration date of the
exchange offer, it will make this prospectus, as amended or supplemented,
available to any broker-dealer for use in connection with any resale subject to
the conditions described under "V.B. The Exchange Offer -- Resale of the
Exchange Notes."

     Nextel will not receive any proceeds from any sale of exchange notes by
broker-dealers. Exchange notes received by broker-dealers for their own account
pursuant to the exchange offer may be sold from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions, through
the writing of options on the exchange notes or a combination of those methods
of resale, at market prices prevailing at the time of resale, at prices related
to the prevailing market prices, or negotiated prices. Any 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 broker-dealer
and/or the purchasers of any exchange notes. Any broker or dealer that
participates in a distribution of the exchange notes may be deemed to be an
"underwriter" within the meaning of the Securities Act of 1933, and any profit
on the resale of exchange notes and any commissions or concessions received by
those persons may be deemed to be underwriting compensation under the Securities
Act of 1933. 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 of
1933.

     Nextel 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 notes and will indemnify the holders of
the exchange notes, including any broker-dealers, against some liabilities,
including some liabilities under the Securities Act of 1933.

                     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, as amended (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

                                      II-1
<PAGE>   70

Indemnification Agreements, an Indemnitee is entitled to indemnification as
provided by Section 145 of the DGCL and to indemnification for any amount which
the Indemnitee is or becomes legally obligated to pay relating to or arising out
of any claim made against such person because of any act, failure to act, or
neglect or breach of duty, including any actual or alleged error, misstatement,
or misleading statement, which such person commits, suffers, permits, or
acquiesces in while acting in the Indemnitee's position with Nextel. The
Indemnification Agreements are in addition to and are not intended to limit any
rights of indemnification which are available under the Nextel Charter or the
Nextel By-laws, any policy of insurance or otherwise. Nextel is not required
under the Indemnification Agreements to make payments in excess of those
expressly provided for in the DGCL in connection with any claim against the
Indemnitee:

          (i) which results in a final, nonappealable order directing the
     Indemnitee to pay a fine or similar governmental imposition which Nextel is
     prohibited by applicable law from paying; or

          (ii) based upon or attributable to the Indemnitee gaining in fact a
     personal profit to which he was not legally entitled including, without
     limitation, profits made from the purchase and sale by the Indemnitee of
     equity securities of Nextel which are recoverable by Nextel pursuant to
     Section 16(b) of the Securities Exchange Act of 1934, as amended (the
     "Exchange Act") and profits arising from transactions in publicly traded
     securities of Nextel which were effected by the Indemnitee in violation of
     Section 10(b) of the Exchange Act or Rule 10b-5 promulgated thereunder.

     In addition to the rights to indemnification specified therein, the
Indemnification Agreements are intended to increase the certainty of receipt by
the Indemnitee of the benefits to which he or she is entitled by providing
specific procedures relating to indemnification.

     The Indemnification Agreements are also intended to provide increased
assurance of indemnification by prohibiting Nextel from adopting any amendment
to the Nextel Charter or the Nextel By-laws which would have the effect of
denying, diminishing or encumbering the Indemnitee's rights pursuant thereto or
to the DGCL or any other law as applied to any act or failure to act occurring
in whole or in part prior to the effective date of such amendment.

ITEM 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

             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the registration statement
        or any material change to such information in the registration
        statement; provided, however, that paragraphs (1)(i) and (1)(ii) do not
        apply if the registration statement is on Form S-3 or Form S-8, and the
        information required to be included in a post-effective amendment by
        those paragraphs is contained in periodic reports filed with or
        furnished to the Commission by the registrant pursuant to Sections 13 or
        15(d) of the Securities Exchange Act of 1934 that are incorporated by
        reference in the registration statement.

          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.

          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.

     (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

                                      II-6
<PAGE>   75

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 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.

     (e) 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.

       Re:    Registration Statement for 9.375% Senior Serial Redeemable Notes
              due 2009

Ladies and Gentlemen:

       We are acting as counsel to Nextel Communications, Inc., a Delaware
corporation (the "Company") in connection with the preparation of the Company's
registration statement on Form S-4 (the Form S-4, including any amendments and
supplements thereto, is referred to herein as the "Registration Statement") as
filed with the Securities and Exchange Commission on December 16, 1999 under
the Securities Act of 1933, as amended (the "Securities Act"). The Registration
Statement relates to the Company's offer to exchange (the "Exchange Offer") up
to $2,000,000,000 aggregate principal amount of its 9.375% Senior Serial
Redeemable Notes due 2009, which have been registered under the Securities Act
(the "Exchange Notes") for any and all of its outstanding 9.375% Senior Serial
Redeemable Notes due 2009, which were issued on November 12, 1999 in a private
placement (the "Private Notes"). The Private Notes were, and the Exchange Notes
will be, issued pursuant to the Indenture, dated as of November 12, 1999 by and
among the Company and Harris Trust and Savings Bank, as Trustee (the
"Indenture").

       As counsel for the Company, and for purposes of this opinion, we have
made those examinations and investigations of legal and factual matters as we
have deemed advisable and have examined originals or copies, certified or
otherwise, identified to our satisfaction as true copies of originals, of those
corporate records, agreements, certificates, 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, necessary or appropriate to enable us
to render the opinion expressed below. We have assumed, without independent
verification, the genuineness and authorization of all signatures, the
conformity to the originals of all copies submitted to us or inspected by us as
certified, conformed, or photostatic copies.

       Based upon the foregoing, and subject to the qualifications and
limitations stated herein, we are of the opinion that the Exchange Notes have
been duly authorized, and when executed by


<PAGE>   2

authorized officers of the Company, authenticated by the trustee, and issued in
accordance with the Indenture and as described in the Registration Statement,
will constitute valid and legally binding obligations of the Company enforceable
in accordance with their terms and entitled to the benefits of the Indenture,
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 filing of this opinion as an exhibit to the
Registration Statement and to the reference to us with respect to this opinion
under the heading "Legal Matters" in the prospectus which is part of the
Registration Statement.

                                         Very truly yours,

       Re:    Exchange Offer for 9.375% Senior Serial Redeemable Notes due 2009

Ladies and Gentlemen:

       We have acted as counsel to Nextel Communications, Inc. (the "Company")
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 offer by the Company to exchange (the "Exchange Offer") the Company's 9.375%
Senior Serial Redeemable Notes due 2009 (the "Exchange Notes") for the Company's
outstanding 9.375% Senior Serial Redeemable Notes due 2009 (the "Outstanding
Notes" and together with the Exchange Notes, the "Notes").

       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 as to the United States federal tax matters set forth under the
caption "United States Federal Tax Consequences" in the prospectus contained in
the registration statement summarizes the principal United States federal income
tax consequences relevant to the Exchange Offer and to the purchase, ownership
and disposition of the 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,

                        INDEPENDENT AUDITORS' CONSENT

We consent to the incorporation by reference in this Amendment No. 1 to
Registration Statement No. 333-92895 of Nextel Communications, Inc. on Form S-4
of our report dated February 22, 1999, appearing in the Annual Report on Form
10-K of Nextel Communications, Inc. for the year ended December 31, 1998, and

Ladies and Gentlemen:

     According to the terms and conditions of the Exchange Offer, I hereby
tender to Nextel the principal amount of Outstanding Notes indicated above. At
the time these notes are accepted by Nextel, and exchanged for the same
principal amount of Exchange Notes, I will sell, assign, and transfer to Nextel
all right, title and interest in and to the Outstanding Notes I have tendered. I
am aware that the exchange agent also acts as the agent of Nextel. By executing
this document, I irrevocably appoint the exchange agent as my agent and
attorney-in-fact for the tendered Outstanding Notes with full power of
substitution to:

          1.  deliver certificates for the Outstanding Notes, or transfer
     ownership of the Outstanding Notes on the account books maintained by DTC,
     to Nextel and deliver all accompanying evidences of transfer and
     authenticity to Nextel, and

          2.  present the Outstanding Notes for transfer on the books of Nextel,
     receive all benefits and exercise all rights of beneficial ownership of
     these Outstanding Notes, according to the terms of the Exchange Offer. The
     power of attorney granted in this paragraph is irrevocable and coupled with
     an interest.

     I represent and warrant that I have full power and authority to tender,
sell, assign, and transfer the Outstanding Notes that I am tendering. I
represent and warrant that Nextel will acquire good and unencumbered title to
the Outstanding Notes, free and clear of all liens, restrictions, charges and
encumbrances and that the Outstanding Notes will not be subject to any adverse
claim at the time Nextel acquires them. I further represent that:

          1.  any Exchange Notes I will acquire in exchange for the Outstanding
     Notes I have tendered will be acquired in the ordinary course of business;

          2.  I have not engaged in, do not intend to engage in, and have no
     arrangement with any person to engage in, a distribution of any Exchange
     Notes issued to me; and

          3.  I am not an "affiliate" (as defined in Rule 405 under the
     Securities Act) of Nextel.

     I understand that the Exchange Offer is being made in reliance on
interpretations contained in letters issued to third parties by the staff of the
Securities and Exchange Commission ("Commission"). These letters provide that
the Exchange Notes issued in exchange for the Outstanding Notes in the Exchange
Offer may be offered for resale, resold, and otherwise transferred by a Holder
of Exchange Notes, unless that person is an "affiliate" of Nextel within the
meaning of Rule 405 under the Securities Act, without compliance with the
registration and prospectus delivery provisions of the Securities Act. The
Exchange Notes must be acquired in the ordinary course of the Holder's business
and the Holder must not be engaging in, must not intend to engage in, and must
not have any arrangement or understanding with any person to participate in, a
distribution of the Exchange Notes.

     If I am a broker-dealer that will receive Exchange Notes for my own account
in exchange for Outstanding Notes that were acquired as a result of
market-making activities or other trading activities (a "Participating
Broker-Dealer"), I acknowledge that I will deliver a prospectus in connection
with any resale of the Exchange Notes. However, by this acknowledgment and by
delivering a prospectus, I will not be deemed to admit that I am an
"underwriter" within the meaning of the Securities Act. If I am a Participating
Broker-Dealer, I will, on a weekly basis during the 90-day period following the
Expiration Date, or any longer period required if use of the prospectus has been
suspended by Nextel, contact counsel to the Initial Purchasers of the
Outstanding Notes at (212) 848-7293 to confirm the availability of the
prospectus for delivery in connection with resales.

     Upon request, I will execute and deliver any additional documents deemed by
the exchange agent or Nextel to be necessary or desirable to complete the
assignment, transfer, and purchase of the Outstanding Notes I have tendered.

     I understand that Nextel will be deemed to have accepted validly tendered
Outstanding Notes when Nextel gives oral or written notice of acceptance to the
exchange agent.

<PAGE>   5

     If, for any reason, any tendered Outstanding Notes are not accepted for
exchange in the Exchange Offer, certificates for those unaccepted Outstanding
Notes will be returned to me without charge at the address shown below or at a
different address if one is listed under "Special Delivery Instructions." Any
unaccepted Outstanding Notes which had been tendered by book-entry transfer will
be credited to an account at DTC, as soon as reasonably possible after the
Expiration Date.

     All authority granted or agreed to be granted by this letter of transmittal
will survive my death, incapacity or, if I am a corporation or institution, my
dissolution and every obligation under this letter of transmittal is binding
upon my heirs, personal representatives, successors, and assigns.

     I understand that tenders of Outstanding Notes according to the procedures
described in the prospectus under the heading "V.F. The Exchange
Offer -- Procedures for Tendering" and in the instructions included in this
document constitute a binding agreement between myself and Nextel subject to the
terms and conditions of the Exchange Offer.


     Unless I have described other instructions in this letter of transmittal
under the section "Special Issuance Instructions," please issue the certificates
representing Exchange Notes issued in exchange for my tendered and accepted
Outstanding Notes in my name, and issue any replacement certificates for
Outstanding Notes not tendered or not exchanged in my name. Similarly, unless I
have instructed otherwise under the section "Special Delivery Instructions,"
please send the certificates representing the Exchange Notes issued in exchange
for tendered and accepted Outstanding Notes and any certificates for Outstanding
Notes that were not tendered or not exchanged, as well as any accompanying
documents, to me at the address shown below my signature. If the "Special
Issuance Instructions" and/or "Special Delivery Instructions" are completed,
please issue the certificates representing the Exchange Notes issued in exchange
for my tendered and accepted Outstanding Notes in the name(s) of, and/or return
any Outstanding Notes that were not tendered or exchanged and send such
certificates to, the person(s) so indicated. I understand that if Nextel does
not accept any of the tendered Outstanding Notes for exchange, Nextel has no
obligation to transfer any Outstanding Notes from the name of the registered
Holder(s) according to my instructions in the "Special Issuance Instructions"
and "Special Delivery Instructions" sections of this document.

                                  INSTRUCTIONS
                    PART OF THE TERMS AND CONDITIONS OF THE
                                 EXCHANGE OFFER


     1. DELIVERY OF THIS LETTER OF TRANSMITTAL AND OUTSTANDING NOTES.  The
tendered Outstanding Notes or a confirmation of book-entry delivery, as well as
a properly completed and a manually signed executed copy or facsimile of this
letter of transmittal and any other required documents must be received by the
exchange agent at its address listed on the cover of this document before 5:00
p.m., New York City time, on the Expiration Date. YOU ARE RESPONSIBLE FOR THE
DELIVERY OF THE OUTSTANDING NOTES, THIS LETTER OF TRANSMITTAL AND ALL REQUIRED
DOCUMENTS TO THE EXCHANGE AGENT. EXCEPT UNDER THE LIMITED CIRCUMSTANCES
DESCRIBED BELOW, THE DELIVERY OF THESE DOCUMENTS WILL BE CONSIDERED TO HAVE BEEN
MADE ONLY WHEN ACTUALLY RECEIVED OR CONFIRMED BY THE EXCHANGE AGENT. WHILE THE
METHOD OF DELIVERY IS AT YOUR RISK AND CHOICE, NEXTEL RECOMMENDS THAT YOU USE AN
OVERNIGHT OR HAND DELIVERY SERVICE RATHER THAN REGULAR MAIL. YOU SHOULD SEND
YOUR DOCUMENTS WELL BEFORE THE EXPIRATION DATE TO ENSURE RECEIPT BY THE EXCHANGE
AGENT. YOU MAY REQUEST THAT YOUR BROKER, DEALER, COMMERCIAL BANK, TRUST COMPANY
OR NOMINEE DELIVER YOUR OUTSTANDING NOTES, THIS LETTER OF TRANSMITTAL AND ALL
REQUIRED DOCUMENTS TO THE EXCHANGE AGENT. DO NOT SEND YOUR OUTSTANDING NOTES TO
NEXTEL.


     If you wish to tender your Outstanding Notes, but:

          (a) your Outstanding Notes are not immediately available;

          (b) you cannot deliver your Outstanding Notes, this letter of
     transmittal and all required documents to the exchange agent before the
     Expiration Date; or

          (c) you are unable to complete the book-entry tender procedure before
     the Expiration Date,

you must tender your Outstanding Notes according to the guaranteed delivery
procedure. A summary of this procedure follows, but you should read the section
in the prospectus titled "V.H. The Exchange Offer -- Guaranteed Delivery
Procedures" for more complete information. As used in this letter of
transmittal, an "Eligible Institution" is any participant in a Recognized
Signature Guarantee Medallion Program within the meaning of Rule 17Ad-15 of the
Exchange Act.

     For a tender made through the guaranteed delivery procedure to be valid,
the exchange agent must receive a properly completed and executed Notice of
Guaranteed Delivery or a facsimile of that notice before 5:00 p.m., New York
City time, on the Expiration Date. The Notice of Guaranteed Delivery must be
delivered by an Eligible Institution and must:

          (a) state your name and address;

          (b) list the certificate numbers and principal amounts of the
     Outstanding Notes being tendered;

          (c) state that tender of your Outstanding Notes is being made through
     the Notice of Guaranteed Delivery; and


          (d) guarantee that this letter of transmittal, or a manually signed
     facsimile of it, or an Agent's Message, in the case of a book-entry
     transfer, the certificates representing the Outstanding Notes, or a
     confirmation of DTC book-entry transfer, and all other required documents
     will be deposited with the exchange agent by the Eligible Institution
     within three New York Stock Exchange trading days after the date of
     execution of the Notice of Guaranteed Delivery.



     The exchange agent must receive your Outstanding Notes certificates, or a
confirmation of DTC book entry, in proper form for transfer, this letter of
transmittal and all required documents within three New York Stock Exchange
trading days after the date of execution of the Notice of Guaranteed Delivery or
your tender will be invalid and may not be accepted for exchange.


     Nextel has the sole right to decide any questions about the validity, form,
eligibility, time of receipt, acceptance or withdrawal of tendered Outstanding
Notes, and its decision will be final and binding. Nextel's interpretation of
the terms and conditions of the Exchange Offer, including the instructions
contained in this

                                        8
<PAGE>   9

letter of transmittal and in the prospectus under the heading "V.E. The Exchange
Offer -- Conditions," will be final and binding on all parties.

     Nextel has the absolute right to reject any or all of the tendered
Outstanding Notes if

          (1) the Outstanding Notes are not properly tendered or

          (2) in the opinion of counsel, the acceptance of those Outstanding
     Notes would be unlawful.

     Nextel may also decide to waive any conditions, defects, or invalidity of
tender of Outstanding Notes and accept such Outstanding Notes for exchange. Any
defect or invalidity in the tender of Outstanding Notes that is not waived by
Nextel must be cured within the period of time set by Nextel.

     It is your responsibility to identify and cure any defect or invalidity in
the tender of your Outstanding Notes. Tender of your Outstanding Notes will not
be considered to have been made until any defect is cured or waived. Neither
Nextel, the exchange agent nor any other person is required to notify you that
your tender was invalid or defective, and no one will be liable for any failure
to notify you of such a defect or invalidity in your tender of Outstanding
Notes. As soon as reasonably possible after the Expiration Date, the exchange
agent will return to the Holder any Outstanding Notes that were invalidly
tendered if the defect of invalidity has not been cured or waived.

     2. TENDER BY HOLDER.  You must be a Holder of Outstanding Notes in order to
participate in the Exchange Offer. If you are a beneficial holder of Outstanding
Notes who wishes to tender, but you are not the registered Holder, you must
arrange with the registered Holder to execute and deliver this letter of
transmittal on his, her or its behalf. Before completing and executing this
letter of transmittal and delivering the registered Holder's Outstanding Notes,
you must either make appropriate arrangements to register ownership of the
Outstanding Notes in your name, or obtain a properly executed bond power from
the registered Holder. The transfer of registered ownership of Outstanding Notes
may take a long period of time.

     3. PARTIAL TENDERS.  If you are tendering less than the entire principal
amount of Outstanding Notes represented by a certificate, you should fill in the
principal amount you are tendering in the last column of the box entitled
"Description of Outstanding Notes." The entire principal amount of Outstanding
Notes listed on the certificate delivered to the exchange agent will be deemed
to have been tendered unless you fill in the appropriate box. If the entire
principal amount of all Outstanding Notes is not tendered, a certificate will be
issued for the principal amount of those untendered Outstanding Notes not
tendered.

     Unless a different address is provided in the appropriate box on this
letter of transmittal, certificate(s) representing Exchange Notes issued in
exchange for any tendered and accepted Outstanding Notes will be sent to the
registered Holder at his or her registered address, promptly after the
Outstanding Notes are accepted for exchange. In the case of Outstanding Notes
tendered by book-entry transfer, any untendered Outstanding Notes and any
Exchange Notes issued in exchange for tendered and accepted Outstanding Notes
will be credited to accounts at DTC.

     4. SIGNATURES ON THE LETTER OF TRANSMITTAL; BOND POWERS AND ENDORSEMENTS;
GUARANTEE OF SIGNATURES.

     - If you are the registered Holder of the Outstanding Notes tendered with
       this document, and are signing this letter of transmittal, your signature
       must match exactly with the name(s) written on the face of the
       Outstanding Notes. There can be no alteration, enlargement, or change in
       your signature in any manner. If certificates representing the Exchange
       Notes, or certificates issued to replace any Outstanding Notes you have
       not tendered are to be issued to you as the registered Holder, do not
       endorse any tendered Outstanding Notes, and do not provide a separate
       bond power.

     - If you are not the registered Holder, or if Exchange Note or any
       replacement Outstanding Note certificates will be issued to someone other
       than you, you must either properly endorse the Outstanding Notes you have
       tendered or deliver with this letter of transmittal a properly completed
       separate bond power. Please note that the signatures on any endorsement
       or bond power must be guaranteed by an Eligible Institution.

                                        9
<PAGE>   10

     - If you are signing this letter of transmittal but are not the registered
       Holder(s) of any Outstanding Notes listed on this document under the
       "Description of The Exchange Notes," the Outstanding Notes tendered must
       be endorsed or accompanied by appropriate bond powers, in each case
       signed in the name of the registered Holder(s) exactly as it appears on
       the Outstanding Notes. Please note that the signatures on any endorsement
       or bond power must be guaranteed by an Eligible Institution.

     - If this letter of transmittal, any Outstanding Notes tendered or any bond
       powers are signed by trustees, executors, administrators, guardians,
       attorneys-in-fact, officers of corporations, or others acting in a
       fiduciary or representative capacity, that person must indicate their
       title or capacity when signing. Unless waived by Nextel, evidence
       satisfactory to Nextel of that person's authority to act must be
       submitted with this letter of transmittal. Please note that the
       signatures on any endorsement or bond power must be guaranteed by an
       Eligible Institution.

     - ALL SIGNATURES ON THIS LETTER OF TRANSMITTAL MUST BE GUARANTEED BY AN
       ELIGIBLE INSTITUTION UNLESS ONE OF THE FOLLOWING SITUATIONS APPLY:


      - If this letter of transmittal is signed by the registered Holder(s) of
        the Outstanding Notes tendered with this letter of transmittal and such
        Holder(s) has not completed the box titled "Special Issuance
        Instructions" or the box titled "Special Delivery Instructions;" or


      - If the Outstanding Notes are tendered for the account of an Eligible
        Institution.


     5. SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS.  If different from the name
and address of the person signing this letter of transmittal, you should
indicate, in the applicable box or boxes, the name and address where Outstanding
Notes issued in replacement for any untendered or tendered but unaccepted
Outstanding Notes should be issued or sent. If replacement notes for Outstanding
Notes are to be issued in a different name, you must indicate the taxpayer
identification or social security number of the person named.


     6. TRANSFER TAXES.  Nextel will pay all transfer taxes, if any, applicable
to the exchange of Outstanding Notes in the Exchange Offer. However, transfer
taxes will be payable by you (or by the tendering Holder if you are signing this
letter on behalf of a tendering Holder) if:

     - certificates representing Exchange Notes or notes issued to replace any
       Outstanding Notes not tendered or accepted for exchange are to be
       delivered to, or are to be registered or issued in the name of, a person
       other than the registered Holder;

     - tendered Outstanding Notes are registered in the name of any person other
       than the person signing this letter of transmittal; or

     - a transfer tax is imposed for any reason other than the exchange of
       Outstanding Notes according to the Exchange Offer. If satisfactory
       evidence of the payment of those taxes or an exemption from payment is
       not submitted with this letter of transmittal, the amount of those
       transfer taxes will be billed directly to the tendering Holder. Until
       those transfer taxes are paid, Nextel will not be required to deliver any
       Exchange Notes required to be delivered to, or at the direction of, such
       tendering Holder.

     Except as provided in this Instruction 6, it is not necessary for transfer
tax stamps to be attached to the Outstanding Notes listed in this letter of
transmittal.

     7. FORM W-9.  You must provide the exchange agent with a correct Taxpayer
Identification Number ("TIN") for the Holder on the enclosed Form W-9. If the
Holder is an individual, the TIN is his or her social security number. If you do
not provide the required information on the Form W-9, you may be subject to 31%
Federal income tax withholding on certain payments made to the Holders of
Exchange Notes. Certain Holders, such as corporations and certain foreign
individuals, are not subject to these backup withholding and reporting
requirements. For additional information, please read the enclosed Guidelines
for Certification of TIN on Substitute Form W-9. To prove to the exchange agent
that a foreign individual qualifies as an exempt Holder, the foreign individual
must submit a Form W-8, Form W-8 BEN or other similar statement, signed under
penalties of perjury, certifying as to that individual's exempt status. You can
obtain the appropriate form from the exchange agent.

     8. WAIVER OF CONDITIONS.  Nextel may choose, at any time and for any
reason, to amend, waive or modify certain of the conditions to the Exchange
Offer. The conditions applicable to tenders of Outstanding Notes in the Exchange
Offer are described in the prospectus under the heading "V.E. The Exchange
Offer -- Conditions."

     9. MUTILATED, LOST, STOLEN OR DESTROYED OUTSTANDING NOTES.  If your
Outstanding Notes have been mutilated, lost, stolen or destroyed, you should

document for further instructions.

bank, trust company, or other nominee for assistance concerning the Exchange

  identification purposes. Payers must be given the numbers whether or not
  recipients are required to file tax returns. Payers must generally withhold

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

PENALTIES
(1) PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER. -- If you
fail to furnish your Taxpayer Identification Number to a payer, you are subject
to a penalty of $50 for each such failure unless your failure is due to
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.
