Item 5.  Other Events.

McCAW INVESTOR TRANSACTIONS.

     Nextel Communications, Inc. ("Nextel"), Digital Radio L.L.C., an entity
controlled by Craig O. McCaw (the "McCaw Investor") and Option Acquisition,
L.L.C.,  an entity  also  controlled  by Craig O.  McCaw  (the  "Purchaser"  and
collectively with the McCaw Investor,  the "McCaw  Companies") have entered into
the  definitive  agreements  implementing  the  terms  of  the  April  11,  1997
agreements reached between Nextel and the McCaw Companies as earlier reported in
Nextel's  Current  Report  on Form 8-K  dated  April 15,  1997,  filed  with the
Securities and Exchange Commission (the "Commission") on April 16, 1997.

     The principal definitive agreements include the Option Exercise and
Lending  Commitment  Agreement dated as of June 16, 1997 between Nextel and
the McCaw Investor (the "Option  Exercise  Agreement"),  the  Contingent  Equity
Instrument  dated as of June 16, 1997 between Nextel and the McCaw Investor (the
"CEI"),  the Option  Purchase  Agreement dated as of June 16, 1997 among Nextel,
Unrestricted  Subsidiary  Funding  Company,  a  subsidiary  of  Nextel,  and the
Purchaser (the "Option Purchase  Agreement"),  two Option Agreements dated as of
June 18, 1997 between Nextel and the Purchaser,  a Registration Rights Agreement
dated as of June 18, 1997 between  Nextel and the Purchaser  (the  "Registration
Rights Agreement") and a First Amendment to Registration  Rights Agreement dated
as of June 18, 1997 among Nextel, the McCaw Investor and the Purchaser,  each of
which is  attached  to this  Current  Report as an exhibit  and is  incorporated
herein by reference.

     Pursuant to the Option Exercise Agreement, the McCaw Investor has
committed  (the  "Option  Commitment")  to exercise  in full its  currently
outstanding  option  (the  "First  Option")  to  purchase  15 million  shares of
Nextel's  Class A Common Stock,  par value $.001 per share (the "Common  Stock")
for an aggregate purchase price of $232.5 million, with the consummation thereof
scheduled  to occur on or  before  July 28,  1997  (the  "Option  Closing").  In
consideration  for the Option  Commitment  and a payment  of a nominal  purchase
price,  Nextel issued to the McCaw Investor the CEI,  which, at any time between
the Option Closing and July 28, 1999,  may be converted,  without any additional
consideration,  into a number of shares of Common Stock to be determined using a
formula based upon the average  closing price for a share of Common Stock during
the 20 trading days  immediately  preceding  the Option  Closing  (the  "Average
Trading Price").  The number of shares of Common Stock into which the CEI may be
converted ranges from no shares, if the Average Trading Price is equal to $15.50
or more,  to a maximum of  approximately  1.6  million  shares,  if the  Average
Trading  Price is $14.00 or less.  The  Option  Closing  is  subject  to certain
limited conditions, as set forth in the Option Exercise Agreement. In connection
with the foregoing,  the McCaw Investor also agreed to provide up to $50 million
in debt financing (subject to certain conditions) to Nextel (the "McCaw Investor
Borrowings").  At the present time, however,  Nextel is not taking steps to meet
the conditions to access the McCaw Investor Borrowings.

     Pursuant to the Option Purchase Agreement, the Purchaser acquired, for an
aggregate  purchase  price of $25 million,  options (which are evidenced by
the Option Agreements attached to this Current Report as Exhibits 10.4 and 10.5)
to purchase a total of 25 million shares of

<PAGE>

Common Stock (the "New Options"), 15 million of which are purchasable at an
exercise  price of $16.00  per share and the  remaining  10 million of which are
purchasable at an exercise  price of $18.00 per share,  at any time through July
28, 1998.  The New Options,  and any shares of Common Stock issued upon exercise
thereof,  are transferrable  subject to certain  limitations.  In addition,  one
direct transferee of the Purchaser will be entitled to designate one nominee for
election  to  Nextel's  Board of  Directors,  provided  that such  party (i) has
exercised  the  transferred  portion of the New Options and  continues to own at
least 10 million shares of Common Stock  obtained on such exercise,  (ii) is not
an  affiliate  of Mr.  McCaw  and  (iii)  does not hold a 5% or  greater  equity
ownership  interest  in any  entity  that  provides  terrestrial-based  wireless
communications services in competition with Nextel in any of its markets. Shares
issuable upon exercise of the New Options will be entitled to certain demand and
piggyback  registration  rights pursuant to the Registration  Rights  Agreement,
which would be assignable to transferees in certain  circumstances  specified in
the Registration Rights Agreement.

NETWORK COVERAGE AND OPERATING MATTERS

     On July 8, 1997, Nextel announced the rollout of its digital wireless
network in Houston  and its  earlier  rollout of such  networks in Oklahoma
City and Tulsa.  Nextel also announced that it added 201,500 digital subscribers
during  the  second  quarter  of 1997 and that as of June 30,  1997  Nextel  had
approximately 624,400 digital subscriber units in service. Nextel also announced
that the average  monthly revenue per unit was  approximately  $63 in the second
quarter of 1997 as compared to approximately $59 in the first quarter. A copy of
the press release  containing  such  announcements  is attached to this Current
Report as Exhibit 99.4 and is incorporated herein by reference.

PROPOSED PREFERRED STOCK OFFERING

     On July 2, 1997, Nextel announced that it proposes to offer 350,000 shares
of Series D Exchangeable  Preferred Stock which are mandatorily  redeemable
in 2009 with a liquidation  preference of $1,000 per share.  A copy of the press
release  containing  such  announcement  is attached to this  Current  Report as
Exhibit 99.3.

FINANCING REQUIREMENTS AND SOURCES

     OVERVIEW.  Nextel is currently implementing a business plan that
contemplates the accelerated and expanded deployment of its advanced mobile
communications   systems   employing   digital   technology  with  a  multi-site
configuration  permitting  frequency  reuse ("Digital  Mobile  networks") in its
domestic  markets  during 1997 and 1998.  Nextel  believes that the  accelerated
deployment  of Digital  Mobile  networks  that  utilize the  digital  technology
developed by Motorola (such technology is referred to as the "integrated Digital
Enhanced Network" or "iDEN",  and the modifications to the first generation iDEN
technology  are  referred to as  "Reconfigured  iDEN") as  contemplated  by this
business  plan  will  better  position  Nextel  both to  achieve  its  strategic
objectives  relating to its United States operations and to prepare for emerging
competition in the wireless  communications  industry,  especially  from certain
current  operators that, on their existing  cellular  frequencies or on personal
communication  services  ("PCS")  frequencies,  are in the process of converting
their  wireless  communications  systems to

<PAGE>

digital technology formats and are moving to provide "nationwide  coverage"
on the resulting systems. To implement such business plan, Nextel estimates that
the external  funding  required to meet the cash needs of its domestic  business
activities  during  the  period  from March 31,  1997  through  the end of 1998,
including  principally  the  funding of  anticipated  capital  expenditures  and
potential  acquisitions  (including  potential  acquisitions  of licenses in the
FCC's  proposed  800  MHz  spectrum  auction)  and  operating  losses,  will  be
approximately $2.5 billion. Nextel estimates that approximately $1.45 billion of
system  infrastructure  and other system capital costs would be incurred  during
the same  period.  As noted  below,  such  estimates  are  based on a number  of
significant assumptions.

     Nextel plans to meet these funding needs from a variety of existing and
proposed or potential  funding  sources  described below including (i) $676
million in borrowings  available as of March 31, 1997 under the existing secured
credit  facility  with  certain  banks (the "Bank Credit  Facility"),  (ii) $195
million in borrowings  available as of March 31, 1997 under the existing secured
credit facility with Motorola,  Inc. and NTFC Capital  Corporation  (the "Vendor
Credit  Facility");  (iii) $250  million in  additional  secured  borrowings
proposed  to be  made  available  pursuant  to the  Bank  Credit  Facility  (the
"Additional Bank Borrowings"); (iv) $50 million in additional secured borrowings
proposed to be made available by Motorola pursuant to the Vendor Credit Facility
(the  "Additional  Vendor  Borrowings");  (v) up to $200  million in  additional
secured  borrowings  (that are to be second in  ranking to the  borrowings  made
pursuant to the Bank Credit  Facility and the Vendor Credit  Facility)  that are
proposed to be made  available by Motorola  (the "Second  Secured  Borrowings");
(vi) $232.5  million in  proceeds  from the  contemplated  exercise of the First
Option by the McCaw Investor (the "McCaw Option  Proceeds";  see "McCaw Investor
Transactions");  (vii) $420 million in proceeds that would be received by Nextel
upon an  exercise  in full of the New Options on or prior to their July 28, 1998
expiration  date (the "New  Options  Proceeds");  (viii)  available  cash,  cash
equivalents and marketable securities totaling  approximately $163 million as of
March 31, 1997;  and (ix) net cash  proceeds  from  qualifying  equity  issuance
transactions  that Nextel is required to  consummate as a condition to obtaining
access to certain of the foregoing funding sources, which involve incurrences of
indebtedness,  under the  terms of  Nextel's  Existing  Indentures  (as  defined
below). The availability of financing pursuant to certain of the funding sources
identified  above  is  subject  to  a  number  of  conditions.   See  "Financing
Requirements and Sources -- Existing and Proposed Funding Sources" below.

     The terms of the indentures relating to Nextel's five outstanding
issues of Senior  Redeemable  Discount Notes (the "Senior Notes"),  as such
indentures  have been amended to date,  including  pursuant to the  supplemental
indentures (the "Supplemental  Indentures") dated June 13, 1997 (the indentures,
as so amended,  the "Existing  Indentures"),  require Nextel to issue new equity
for cash as a condition  to  obtaining  access to all  amounts not  constituting
"Permitted  Indebtedness"  (as such term is defined in the Existing  Indentures)
under the Bank Credit  Facility and the Vendor Credit  Facility,  the Additional
Bank  Borrowings,  the  Additional  Vendor  Borrowings  and the  Second  Secured
Borrowings  referred to above.  Assuming that Nextel is able to raise sufficient
new equity  proceeds  to allow full  access to such  financing  sources,  Nextel
believes that such financing  sources and new equity proceeds,  coupled with the
Nextel's  cash on hand,  the $232.5  million in McCaw  Option  Proceeds,  and an
assumed exercise in full of the New Options resulting in receipt of $420 million
in New  Options  Proceeds  will  provide  funds  that in

<PAGE>

the  aggregate  will be substantially  sufficient to implement  Nextel's
business plan and meet the cash needs of its other domestic business activities
through 1998.

     If, among other things, Nextel's plans change, its assumptions regarding
its funding needs  associated  with the  deployment  of its Digital  Mobile
networks prove to be inaccurate,  it consummates  acquisitions or investments in
addition to those  currently  contemplated  or at prices  higher than  currently
contemplated,  it experiences  growth in its business or subscriber base greater
than it  presently  is  anticipating,  it  experiences  unanticipated  costs  or
competitive  pressures,  the New Options are not  exercised  in full and the New
Options  Proceeds are not received,  or if the net proceeds from the issuance of
new equity are not sufficient to permit full access to such financing sources or
if such new equity  proceeds  together  with the proceeds from the other sources
referred to above  otherwise  prove to be  insufficient  to meet such cash needs
through 1998,  Nextel would be required to seek additional  capital.  Nextel may
also require significant  additional capital in years subsequent to 1998 to fund
further deployment of its Digital Mobile networks and for other purposes. Nextel
may seek to raise such additional  capital from public or private equity or debt
sources.  There  can be no  assurance  that  Nextel  will be able to raise  such
capital on  satisfactory  terms,  if at all.  See  "Financing  Requirements  and
Sources -- Existing and Proposed Funding Sources" below.

     EXISTING AND PROPOSED FUNDING SOURCES.  The following is a summary of
certain of the existing and proposed funding sources presently contemplated to
be used by Nextel to meet its funding needs.

     The Bank Credit Facility provides for up to $1,655 million of financing
consisting  of $1,085  million  revolving  loans and $570  million  in term
loans.  Borrowings  under the Bank  Credit  Facility  are ratably  secured  with
borrowings  under the  Vendor  Credit  Facility  by liens on assets of  Nextel's
domestic  operating   subsidiaries,   bear  interest  payable  quarterly  at  an
adjustable  rate  calculated  based  either on the prime rate or LIBOR (8.19% to
8.81% as of June 30,  1997) and mature over  periods from March 31, 2001 to June
30, 2003. At June 30, 1997, Nextel had drawn approximately $1,441 million of its
available  financing  under the Bank Credit  Facility,  leaving an  aggregate of
approximately  $214 million  available for borrowing under such facility subject
to the satisfaction or waiver of customary borrowing conditions.

     The Vendor Credit Facility provides for up to $345 million of financing
consisting of a $195 million revolving loan and $150 million in term loans.
The Vendor Credit Facility provides  financing for the purchase of equipment and
ancillary products (such as switches) and related services. Borrowings under the
Vendor Credit Facility are ratably secured with borrowings under the Bank Credit
Facility by liens on assets of Nextel's domestic  operating  subsidiaries,  bear
interest  payable  quarterly  at 2% over the prime  rate  (10.50% as of June 30,
1997) and mature over periods from March 31, 2001 to March 31, 2003. At June 30,
1997,  Nextel had drawn  approximately  $227 million of its available  financing
under the Vendor  Credit  Facility  leaving an aggregate of  approximately  $118
million  available for borrowing under such facility subject to the satisfaction
or waiver of customary borrowing conditions.

     The agreement related to the Bank Credit Facility (the "Bank Credit
Agreement")  contemplates  that,  with the consent of the lenders holding a
majority of the outstanding  loan

<PAGE>

amounts  and  the  remaining  commitment  amounts  under  the  Bank  Credit
Agreement  and under the agreement  related to the Vendor  Credit  Facility (the
"Vendor Credit  Agreement"),  Nextel may borrow up to $250 million in Additional
Bank  Borrowings  (subject to certain  limitations)  pursuant to the Bank Credit
Facility. Nextel has received a proposal from certain banks with respect to $250
million in  Additional  Bank  Borrowings  which would  consist  entirely of term
loans,  would be secured  ratably  with other  borrowings  under the Bank Credit
Facility and Vendor Credit  Facility,  would bear interest at an adjustable rate
based on either the prime rate or LIBOR and would mature on June 30, 2003.

     The Bank Credit Agreement and the Vendor Credit Agreement also contemplate
that borrowings under the Vendor Credit Facility may be increased up to $50
million in Additional Vendor Borrowings (subject to certain limitations). Nextel
and Motorola have reached an  understanding  regarding the terms on which Nextel
may  borrow  $50  million  in  Additional  Vendor  Borrowings  in the form of an
additional  term loan that will be secured ratably with other  borrowings  under
the Vendor Credit Facility and borrowings under the Bank Credit  Facility,  will
bear interest at 2% over the prime rate and will mature on March 31, 2003.

     Nextel has also reached an understanding with Motorola regarding the terms
and conditions  pursuant to which Nextel could access up to $200 million in
Second Secured Borrowings and up to an additional $200 million in Senior Secured
Borrowings.  Such understanding  contemplates that the Second Secured Borrowings
will be in the form of secured term loans available prior to March 31, 1999 that
will be second in ranking  to  borrowings  under the Bank  Credit  Facility  and
Vendor  Credit  Facility,  will bear  interest at a rate equal to .75% below the
previous  months' average yield of Nextel's 11-1/2% Senior  Redeemable  Discount
Notes due 2003 and will mature on June 30, 2003. Availability of such additional
financing  from Motorola is subject to a number of conditions  including,  among
others,  with respect to the Second Secured  Borrowings,  the prior borrowing of
all amounts  available  under the Vendor  Credit  Agreement  (including  the $50
million in Additional  Vendor  Borrowings  pursuant thereto described above) and
pursuant to Nextel's existing Bank Credit Agreement (including,  with respect to
the second $100 million of the Second Secured Borrowings,  the borrowing of $250
million in Additional Bank  Borrowings),  Nextel's receipt of the $232.5 million
in McCaw Option  Proceeds,  and the receipt of the approval of a majority of the
secured parties under the Vendor Credit Agreement and the Bank Credit Agreement.
The  availability  of the Senior  Secured  Borrowings  is subject to a number of
additional  conditions,  including the unanimous approval of the secured parties
under the Bank Credit Agreement and the Vendor Credit  Agreement.  Nextel is not
currently  taking steps to meet such  additional  conditions  and,  accordingly,
Nextel has assumed for planning purposes that the Senior Secured Borrowings will
not be available during 1997 and 1998.

     Nextel has obtained written proposals or commitments from the relevant
lending  parties  relating  to, and has  obtained  certain of the  required
consents and approvals of third parties required to access,  the Additional Bank
Borrowings,  the Additional Vendor Borrowings and the Second Secured Borrowings.
Nextel and the relevant  lending  parties  contemplate  negotiating and entering
into appropriate  definitive agreements  implementing the terms of the financing
arrangements  relating to the Additional Bank Borrowings,  the Additional Vendor
Borrowings and the Second Secured Borrowings,  as described above, and Nextel is
now or shortly  will

<PAGE>

commence  seeking the  remaining  consents  and  approvals required to gain
access to such additional financing.

     To the extent any of the proceeds from equity issuances or financing
arrangements  described  above are not  available or are not  sufficient to
meet Nextel's funding needs, it will be necessary for Nextel to obtain alternate
sources of  financing.  If such  additional  financing  were in the form of debt
rather  than  equity,  Nextel's  receipt  of net cash  proceeds  from new equity
investments  may be  required  to permit the  incurrence  of such debt under the
Existing Indentures.

     The availability of borrowings pursuant to the Bank Credit Facility and
the Vendor Credit Facility is, and the  availability of the Additional Bank
Borrowings,  the Additional Vendor Borrowings and the Second Secured Borrowings,
if structured  successfully,  is expected to be, subject to certain  conditions,
and there can be no assurance that such conditions will be met. Moreover,  there
can be no assurance that the Additional Bank Borrowings,  the Additional  Vendor
Borrowings or the Second  Secured  Borrowings  will be  available,  that the New
Options will be exercised  and that Nextel will receive the proceeds  therefrom,
or that any of the other outstanding  options,  including the First Option, will
be  exercised.  The Bank Credit  Facility,  the Vendor  Credit  Facility and the
Existing Indentures contain and will continue to contain provisions that operate
to limit the amount of borrowings  that may be incurred by Nextel.  In addition,
Nextel's  capital  needs,  and its  ability to  adequately  address  those needs
through debt or equity funding sources, are subject to a variety of factors that
cannot presently be predicted with certainty,  such as the commercial success of
Nextel's  Digital  Mobile  networks,  the amount and timing of Nextel's  capital
expenditures  and operating losses and the market price of the Common Stock. See
"Forward Looking Statements."

     Nextel currently is aware of numerous factors and considerations, any one
or more of which could have a material  effect on the timing  and/or amount
of the future  funding to be required  by Nextel,  but Nextel  cannot  currently
quantify  with  precision  either the  magnitude or the certainty of the effects
associated with any such factors.  These factors include:  (i) the timing of the
anticipated 800 MHz spectrum auction process, and the amounts required to be bid
to acquire any or all of the available spectrum blocks in the major metropolitan
market areas where Nextel currently operates, or currently plans to operate, its
Digital  Mobile  networks  and the amounts  that may be  required to  accomplish
retuning or  acquisition of 800 MHz incumbent  channels in spectrum  blocks that
may be acquired by Nextel in the 800 MHz spectrum auction process; (ii) the cash
amounts,  if any,  received by Nextel in connection  with its offering of Common
Stock to holders of Nextel's  Senior Notes who consented to the  amendments  and
waivers contained in the Supplemental  Indentures (assuming consummation of such
offering);  (iii) the  uncertainty  with respect to the success and/or timing of
the  continuing   development   and  deployment   activities   relating  to  the
Reconfigured  iDEN  technology  format  and,  assuming   successful  and  timely
complection  of such  efforts,  the  uncertainty  with respect to the success of
commercial  introduction  and customer  acceptance  of Nextel's  Digital  Mobile
network services in new market areas using such  technology;  (iv) the potential
commercial  opportunities  and  risks  associated  with  implementation  of  the
accelerated  business  plan that Nextel  currently is pursuing;  and (v) the net
impact on Nextel's capital budget of certain developments  currently expected to
increase capital needs (e.g.,  the additional  capital needed if Nextel acquires
for cash additional  spectrum in certain markets to increase the capacity and/or
efficiency of Nextel's  operating

<PAGE>

Digital Mobile networks in such markets,  the additional capital needed for
more  extensive  construction  of Digital Mobile  networks in additional  market
areas  acquired  or that may be  acquired  in the  future  and the  expenditures
associated with analog SMR station construction requirements under the currently
effective FCC 800 MHz channel  licensing  approach) that may be offset  (whether
wholly  or  partially)  by  other  developments  anticipated  to (or to have the
potential  to)  reduce  capital  needs  (e.g.,  co-location  of  antenna  and/or
transmitter  sites with other  providers  of wireless  services in the  relevant
markets,  reductions in infrastructure  and subscriber unit prices obtained from
Motorola pursuant to the equipment  purchase  agreements with Motorola including
the  new  agreement  entered  into on  March  27,  1997,  alternative  and  more
economical  means  for  increasing  system  capacity,  other  than  constructing
additional cell sites and/or installing  additional base radios,  such as use of
so-called "smart antennas," mini-cells and software-driven  and/or system design
performance  enhancements).  Many of the foregoing  involve  elements  wholly or
partially beyond Nextel's control or influence. Other considerations in addition
to the factors  identified above may significantly  affect Nextel's decisions to
seek additional financing, including general economic conditions,  conditions in
the  telecommunications   and/or  wireless   communications   industry  and  the
feasibility and attractiveness of structuring particular financings for specific
purposes   (e.g.,   separate   capital-raising   activities   with   respect  to
international activities and opportunities). See "Forward Looking Statements."

     Nextel has had and may in the future have discussions with third parties
regarding  potential equity investments and debt financing  arrangements to
satisfy actual or anticipated  financing needs. Nextel has agreed, under certain
circumstances,  not to  grant  superior  governance  rights  to any  third-party
investor without Motorola's consent,  which may make securing equity investments
more  difficult.   The  ability  of  Nextel  to  incur  additional  indebtedness
(including,  in  certain  circumstances,  indebtedness  incurred  under the Bank
Credit  Agreement  and/or  under the  Vendor  Credit  Agreement)  is and will be
limited by the terms of the Existing  Indentures,  the Bank Credit Agreement and
the Vendor  Credit  Agreement.  The Bank Credit  Agreement and the Vendor Credit
Agreement also require Nextel and its relevant  subsidiaries  at specified times
to comply with certain financial covenants or ratios including certain covenants
and ratios specifically related to leverage.

     At present, other than the proposed preferred stock offering described in
"Proposed Preferred Stock Offering," and the existing or proposed equity or
debt financing arrangements that have been consummated and/or disclosed,  Nextel
has no  commitments  or  understandings  with any third  parties  to obtain  any
material amount of additional equity or debt financing.  Moreover, no assurances
can be made that Nextel will be able to obtain any such additional  financing in
the  amounts  or at the  times  such  financing  may be  required,  or that,  if
obtained,  any  such  financing  would  be  on  acceptable  terms.  Nextel  also
anticipates that it will continue to experience significant operating losses and
negative net cash flows during the ongoing start up phase of the Digital  Mobile
networks over the next several years. Accordingly, there can be no assurances as
to whether or when the operations of Nextel will become profitable.  As a result
of  Nextel's  anticipated  continuing  losses,  the  uncertainty  regarding  the
exercise of options and warrants,  the  availability of financing under the Bank
and Vendor Credit  Facilities and, if successfully  structured and  established,
under the Additional Bank Borrowings,  the Additional  Vendor Borrowings and the
Second Secured Borrowings, and the impact of Reconfigured iDEN

<PAGE>

and other matters  discussed  above,  there can be no assurance that Nextel
will have adequate capital to implement the nationwide  build-out of its Digital
Mobile  networks in accordance  with its business  plan.  Failure to obtain such
financing  could result in the delay or  abandonment  of some or all of Nextel's
acquisition,  development and expansion plans and expenditures, which could have
a material  adverse  effect on Nextel's  business  prospects and limit  Nextel's
ability  to make  principal  and  interest  payments  on its  indebtedness.  See
"Forward Looking Statements."

FORWARD LOOKING STATEMENTS

     "SAFE HARBOR" STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT
OF 1995:  A number of the  matters  and  subject  areas  discussed  in this
Current  Report that are not  historical  or current  facts deal with  potential
future  circumstances  and  developments.  The  discussion  of such  matters and
subject areas is qualified by the inherent risks and  uncertainties  surrounding
future  expectations  generally,  and also may  materially  differ from Nextel'
actual future  experience  involving any one or more of such matters and subject
areas. Nextel has attempted to identify, in context, certain of the factors that
it currently  believes may cause actual future  experience and results to differ
from Nextel's  current  expectations  regarding  the relevant  matter or subject
area.  The operation and results of Nextel's  wireless  communications  business
also may be subject to the effect of other risks and  uncertainties  in addition
to the relevant qualifying factors identified  elsewhere in this Current Report,
including,  but not limited to,  general  economic  conditions in the geographic
areas and occupational  market segments that Nextel is targeting for its Digital

<PAGE>

"Option Purchase Agreement") that, among other things, entitles Option
Acquisition to acquire two options to purchase up to 25 million shares of
Common Stock (the "New Options").

                               Agreement

      NOW THEREFORE, in consideration of the recitals and the mutual
covenants of this Agreement, the parties agree:


      Article 1.  Commitment to Exercise Option and Issuance of CEI.

          1.1  Commitment to Exercise Option.  The Option Agreement (First
Tranche) issued by the Company to Investor on July 28, 1995 (the "First
Option") will be exercised, in full, at the Closing.

          1.2   Payment for CEI.  Upon the execution and delivery hereof,
Investor shall pay the Company $1,610 in cash, as payment in full of the
purchase price for the CEI (as described in Section 1.3 below), and the
Company, shall issue and deliver the CEI to Investor.

          1.3   Issuance of CEI.  Upon the execution and delivery hereof, the
Company shall issue to Investor a Contingent Equity Instrument substantially in
the form of Exhibit A (the "CEI") that is potentially exercisable at and after
the Closing until July 28, 1999 for up to that number of shares as determined
at the Closing in accordance with Exhibit B; provided, that if the CEI would
(under Exhibit B) be exchangeable for zero shares, the CEI shall expire
automatically and shall be of no further force or effect at the Closing, and
shall be delivered by the Investor at the Closing to the Company for
cancellation.  The CEI, when issued, will be free and clear of all Encumbrances
(other than as expressly provided in this Agreement or the CEI).

          1.4    Pre-Closing.  Upon obtaining the Noteholder Consents, the
Company will notify Investor (and will provide confirmation from the Trustee of
the receipt of such Consents and copies of the related supplemental indentures)
and Investor will promptly execute and deliver to the Company the exercise
notice

CLCORP01 Doc:230313_4                  2

<PAGE>

for the First Option in the form attached to the First Option (the "Exercise
Notice").

          1.5   Closing.  (a)  The closing of the exercise of the First Option
and the determination of the number of shares of Common Stock issuable upon
exercise of the CEI (the "Closing") is to occur after all of the conditions
(assuming all such conditions have been fulfilled or waived) set forth in
Article 2 have either been fulfilled or waived, but in no event later than
Monday, July 28, 1997.  At the Closing,

                 (i) Investor will pay, by wire transfer of immediately
          available funds to an account designated in writing by the Company,
          $232,500,000 to exercise the First Option;

                 (ii) if the proviso of the first sentence of Section 1.3
          applies, Investor will deliver the CEI to the Company for
          cancellation; in any other case, Investor and the Company shall
          execute and deliver a written instrument confirming the number of
          shares issuable upon exercise of the CEI determined in accordance
          with Exhibit B, which written instrument shall be attached to the
          CEI;

                 (iii) the Company will cause its transfer agent to issue to
          investor a certificate for 15,000,000 shares of Common Stock; and

                  (iv) at the request of either party, the parties will execute
          and deliver any agreements or other documents necessary to evidence
          the satisfaction or, if appropriate, the waiver  of any conditions to
          Closing set forth in Article 2.

          (b)  If no request is made under Section 1.5(a)(iv), the consummation
of the Transactions described in Section 1.5(a) is conclusive evidence that the
parties consider that all conditions to Closing have been satisfied or the
appropriate party or parties have waived the failure of a condition to be
satisfied and neither party after such Closing shall be allowed to assert
non-satisfaction or invalid waiver of any of such conditions for any purpose.
The preceding sentences shall not apply to the extent that a party
intentionally conceals facts or

CLCORP01 Doc:230313_4                    3

<PAGE>
intentionally misrepresents facts that, if disclosed, would have resulted in
one or more conditions to the other party's obligations not having been
satisfied.

          1.6   Legend.   The shares certificate issued to Investor at the
Closing as contemplated in Section 1.5(a)(iii), and any instrument(s) or
certificate(s) representing the CEI (or any part thereof, including
any shares issued upon exercise of any part of the CEI) shall bear the
following legend, together with any and all other legends as may be required
pursuant to applicable law (and the Company may issue appropriate corresponding
stop transfer instructions to any transfer agent for any of such securities):

          (the "Act"),  or under any applicable state law and may not be
          transferred,  sold or otherwise disposed of in the absence of an
          effective  registration under the Act or such laws or an opinion of
          counsel reasonably satisfactory to the Company that such registration
          is not  required  under  the Act or such  laws and the rules and
          regulations promulgated thereunder.

          The securities represented by this certificate or instrument are
          subject to certain restrictions on transfer and voting as set forth
          in the Securities Purchase Agreement, dated as of April 4, 1995, as
          amended, a copy of which is on file at the principal executive
          offices of the Company.  Any registration of transfer of such
          securities on the books of the Company will be subject to compliance
          with such restrictions.

          1.7    Stamp Tax.   The Company shall pay all stamp and other taxes,
if any, which may be payable in respect to the issuance, sale and delivery to
Investor of the CEI and shall save Investor harmless against any loss or
liability resulting from nonpayment or delay in payment of any such tax.

CLCORP01 Doc:230313_4                   11

<PAGE>

          4.1 Status, Power and Authority.  Investor is a limited liability
company duly formed and validly existing under the laws of the State of
Washington and has all requisite corporate or other power and authority to own
or lease and operate its properties, to carry on its business as now conducted

and similar amounts due to the State of Washington and has prepared and filed
with the appropriate authorities of the State of Washington all reports,
returns and similar items as required by, and is substantially in compliance
with, the requirements of applicable laws. To Investor's knowledge, there are
no existing conditions or circumstances that could result in the revocation of
Investor's status, qualification or existence as a limited liability Company
under the laws of the State of Washington.  Investor is duly qualified and in
good standing in each jurisdiction in which the property owned, leased or
operated by it or the nature of the business conducted by it makes such
qualification necessary, except where the failure to be in good standing or so
qualified would not, in the aggregate, have a material adverse effect on the
ability of Investor or any of its Affiliates to perform its obligations under
this Agreement or any other Transaction Agreement to which it is a party.

          4.2  Non-Contravention. (a)  The execution, delivery and performance
of this Agreement and the other Transaction Agreements and the consummation
of the Transactions in accordance with the terms hereof and thereof by Investor
and by each Affiliate of Investor who is a party thereto will not result in any
violation of or conflict with, constitute a default (with or without notice or
the lapse of time) under, or give rise to a right of termination, cancellation,
or  acceleration  of, or result in the imposition of any Encumbrance under, or
require any consent (other  than such  consents as are listed in the Investor
Disclosure Statement), under, any term of (i) the limited liability company or
operating agreement of Investor, or (ii) any  note,  bond,  debt  instrument,
mortgage, indenture or other agreement or instrument or, except as set forth in
Section 4.3,  any Law or  Order, by which Investor  or any such  Affiliate  of
Investor may be bound, except where such violation,  conflict or

CLCORP01 Doc:230313_4                  12

<PAGE>

default,  right of termination,  cancellation or  acceleration,  imposition of
an Encumbrance or failure to obtain such consent, individually or in the
aggregate, would not have a material adverse effect on the ability of Investor
or any such Affiliate of Investor to perform its obligations under this
Agreement and the other Transaction Agreements to which it is a party.

          (b) Each consent identified on the Investor Disclosure Statement has
been obtained and is in full force and effect.

          4.3 Consents and Approvals. (a) The Investor Disclosure Statement
lists (i) all Authorizations that to the knowledge of Investor are required
to be made, filed, given or obtained by Investor or its Affiliates with, to or
from any Governmental Authority in connection with the Transactions contemplated
to  occur  at or  prior to the Closing  to  which  it is a party  and (ii) all
consents, approvals and waivers required to be given by, or obtained from, any
other Persons to or by Investor or its Affiliates  in  connection  with the
consummation of any of the other Transactions contemplated to occur at or prior
to the  Closing  to which it is a  party, other  than  those  Authorizations,
consents, approvals and waivers as to which the failure to make,  file, give or
obtain, individually or in the aggregate, would not have  a material  adverse
effect on the  ability of Investor or any of its  Affiliates to  perform  its
obligations under this Agreement and the other Transaction Agreements to which
it or any such Affiliate is a party.

          (b) Investor and each of its Affiliates has made, filed, given or
obtained all Authorizations and has been given or obtained all consents,
approvals or waivers of any other Persons necessary for Investor or such
Affiliate to perform its obligations under this Agreement and the Transaction
Agreements at or prior to the Closing, and no further Authorizations or
consents, approvals or waivers of any other Persons are required of Investor or
any such Affiliate to perform its obligations under this Agreement and the
Transaction Agreements at or prior to the Closing.

          4.4  Investment Intent. Investor is acquiring the CEI, and will be
acquiring the Common Stock upon exercise of the CEI for its own account and
with no present intention of distributing or selling the CEI or Common Stock
received upon conversion or exercise of any thereof, in violation of the
Securities Act or

CLCORP01 Doc:230313_4                  13

<PAGE>

any applicable state securities law.  Investor will not sell or otherwise
dispose of the CEI.  Investor will not sell or otherwise dispose of shares
of Common Stock received upon exercise of the CEI, unless such sale or other
disposition has been registered or is exempt from registration under
the Securities Act and has been registered or qualified or is exempt from
registration or qualification under applicable state securities laws. Investor
understands that the CEI has not been registered under the Securities Act by
reason of its contemplated issuance in transactions exempt from the
registration and prospectus delivery requirements of the Securities Act
pursuant to Section 4(2) thereof including Rule 506 of Regulation D, and that
the reliance of the Company on this exemption is predicated in part on these
representations and warranties of Investor.

as such term is defined in Rule 501 of Regulation D promulgated under the
Securities Act and has such knowledge and experience in financial and business
matters that it is capable of evaluating the merits and risks of the
investments to be made by it hereunder.

          4.6   Authorization of Agreements. (a) This Agreement and each of the
other Transaction Agreements to which Investor or any of its Affiliates is a
party and the consummation of the Transactions have been approved by all
requisite action of the members of Investor (no other action, including,
without limitation, action of any managers of Investor, being necessary) and by
each other Affiliate of Investor who is a party thereto.

          (b) This Agreement has been and, when executed, each of the other
Transaction Agreements to which Investor or any of its Affiliates is a party
will have been, duly executed and delivered by an authorized member of Investor
and by each other Affiliate of Investor and constitutes a valid and binding
agreement of Investor or of such Affiliate, enforceable against Investor or
such Affiliate of Investor  in  accordance  with its terms,  except as may be
limited by applicable bankruptcy,  insolvency,  reorganization,  moratorium and
other similar laws of general application  which may affect the  enforcement of
creditors' rights generally and by general equitable principles.

          4.7  Brokers and Finders.  Neither Investor nor any of its Affiliates
has employed any investment banker, broker, finder, consultant or intermediary
in connection with the transactions contemplated by this Agreement, and no such
Person would be entitled, pursuant to the terms of any agreement or arrangement
with Investor or any of its Affiliates, to any investment banking, brokerage,
finder's or similar fee or commission in connection with this Agreement or the
transactions contemplated hereby.

          4.8  Acquisition of Voting Securities.  Except as expressly provided

Exchange Act) of any securities of the Company that are entitled to vote in the
election of Directors or (b) with respect to corporate governance matters

condition or contingency), in amounts sufficient to permit Investor to perform
its obligations under this Agreement and the other Transaction Agreements.

          Article 5.  Certain Covenants.

          5.1  Public Announcements. Except as required by Law, the exercise of

NASDAQ-NM) on which the Company's securities are listed, prior to the Closing
Date, the form and content of all press releases or other public communications
of any sort relating to the subject matter of this Agreement or any other
Transaction Agreement, and the method of their release, or publication thereof
by any of the parties hereto or their

CLCORP01 Doc:230313_4                  15

<PAGE>

respective Affiliates, shall be subject to the prior approval of each of the
parties hereto, which approval shall not be unreasonably withheld or delayed.
To the extent reasonably requested by any party hereto, following the Closing

cooperation to the other parties in connection with the issuance of further
press releases or other public documents describing the Transactions.

          5.2  Further Assurances. Each party shall execute and deliver such
     additional  instruments  and other documents  and shall take such  further
actions as may be necessary or appropriate  to effectuate, carry out and comply
with all of the terms of each of the  Transaction Agreements to which it or any
of its Affiliates is a party and the transactions contemplated thereby. Without
limiting the generality of the preceding sentence, the Company and the Investor
shall not (and shall not permit their Affiliates to) take any action or actions
at or prior to the  Closing  that would (a) cause or reasonably  be expected to
cause any  Authorization or any consent, approval or waiver of any other Person
that has been made, filed, given or obtained in connection with the Transactions
to be withdrawn or terminated or to otherwise cease to be effective, (b) require
any additional  Authorization or any additional  consent, approval or waiver of
any other Person to be made,  filed, given or obtained in connection  with the
Transactions or (c) cause any financing sources contemplated by Section 4.10 to
be unavailable or cause the availability of the funding thereunder to be subject
to any material condition or contingency.

          5.3  Cooperation.  The Company and Investor each agree to (and to
cause their Affiliates to) cooperate with the other to consummate the
Transactions.

           Article 6.  Investor Loan Commitment.

          6.1  Lending Commitment. (a) Investor commits to enter into a loan
facility (the "Loan Facility") with a Subsidiary of the Company providing for
principal advances of up to $50,000,000 (the "Commitment Amount").  The terms
and conditions of the loan facility will parallel the terms and conditions of
the Motorola Trance E Senior Secured Loan facility in a principal amount up to
$200,000,000 and will rank pari passu with such facility.  The terms will be
consistent with the Term Sheet for Debt Financing,

CLCORP01 Doc:230313_4                  16

<PAGE>

dated as of March 26, 1997, between the Company and Motorola filed as Exhibit
10.36 to the Company report on Form 10-K for the fiscal year ended December 31,
1996, as the same may be amended, from time to time, by the Company and
Motorola, and this Agreement.

          (b) On the date of the first borrowing pursuant to the Loan Facility,
the Company will issue to Investor warrants to purchase up to 250,000 shares of
Common Stock at an exercise price equal to the average closing price for a
share of Common Stock on the NASDAQ-NM during the twenty (20) trading days
immediately preceding the date of the first borrowing pursuant to the Loan
Facility.  Such warrants shall contain other customary terms and shall be
exercisable from the date on which the first borrowing pursuant to the Loan
Facility occurs until the fifth anniversary of such date.

          6.2  Reduction in Commitment. The Commitment Amount is to be reduced
by $20 for every $100 of Qualifying Equity Proceeds received by the Company
after the date hereof and before the Company has drawn down the Commitment
Amount.  "Qualifying Equity Proceeds" means cash received by the Company upon
issuance of equity securities but does not include (i) amounts received as a
result of the exercise of the "First Option," or the "Second Option," "Third
Option" or "Incentive Option" (as those terms are defined in the Securities
Purchase Agreement), (ii) amounts received in connection with the purchase
(but not the exercise) of the New Options, or (iii) amounts received as a
result of the exercise of options to purchase up to 3 million shares of Common
Stock originally issued to Motorola in connection with equipment purchase and
financing arrangements entered into in 1991 between the Company and Motorola.

          6.3  Deemed Waiver For Investor. Investor, its Affiliates and the
Directors elected by Investor to the Board (acting as members of the Board as a
whole or on its committees) may be required to act to satisfy or to take action
that will bring about the satisfaction of one or more conditions to the
Motorola Tranche E Senior Secured Financing or the financing described in
Section 6.1(a).  If any condition to the financing described in Section 6.1(a)
has not been satisfied, in whole or in part, because of any action or inaction
by Investor, by any of its Affiliates or by any Director elected by Investor,
that condition (by such action or inaction) shall be deemed waived by

CLCORP01 Doc:230313_4                  17

<PAGE>

Investor.  If any waiver occurs under this Section 6.3, Investor must fund its
financing commitment despite the failure of the conditions, and  Investor
cannot raise the condition as the basis for any claim under this Agreement,
under the financing contemplated by Section 6.1(a) or for any other purpose
whatsoever nor can Investor seek any remedy for the failure.

          6.4  Further Documents. As promptly as practicable after the
execution  of loan  documents  evidencing the Motorola  Tranche  E Senior
Secured  Loan,  the  Company and  Investor will each  execute and deliver loan
documents to effectuate Investor's commitment made in Section 6.1, together
with such other agreements and documents as are, in the reasonable judgment of
either party, necessary to carry out the intent of this Article 6.

          Article 7.  Amendment to Securities Purchase Agreement.

          7.1  End of Lock-Up Period. Effective upon the Closing, the
Securities Purchase Agreement is amended to delete Section 8.3(g).  From and
after the Closing, Section 8.3(g) is void and has no further force or effect.

          7.2   No Transfer of CEI.  Effective upon the Closing, Section 8.3(f)
of the Securities Purchase Agreement is amended to add the CEI to the list of
Company securities owned by Investor that are subject to restriction on
Transfer by deleting the word "or" before item (D) and adding, before the word
except: "or  (E) the Contingent Equity Instrument issued under the Option
Exercise and Lending Commitment Agreement dated June 16, 1997".

                              EXHIBIT A



          This Contingent Exercise Instrument ("CEI") will be issued to be
exchangeable for a number ("N") of shares of Nextel Common Stock determined in
accordance with the following formula:

          (a)  if X is $14.00 or less, N equals 1,607,143 shares;

          (b)  if X is $15.50 or more, N equals zero shares; and

          (c)  in any other case, N equals the number of shares resulting
               from the equation [D multiplied by 15,000,000], divided by X.,

where X is the average  closing price for a share of Nextel Common Stock on
the  NASD-National Market during the 20 trading days immediately  preceding the
date  of the  Closing  (as defined  in  Section 1.5),  and D is the  result  of
subtracting X from $15.50. By way of example, if X is $14.50, then N
(determined in accordance  with clause (c) above) would be 1,034,482  shares
(rounded up to the nearest whole share),  i.e., 1.00 times
15,000,000 = 15,000,000  divided by 14.50 = 1,034,482.76.

Agreement, $1,610.00 paid to the Company upon the execution and delivery of
this CEI, and other good and valuable consideration, the sufficiency and
receipt of which is hereby acknowledged, the Company agrees with Buyer as

          1. GRANT OF CEI.

          1.1  Grant.  The Company hereby grants to Buyer this CEI, exercisable
as provided herein in whole or in part at any time and from time to time during
the period from (A) the date that Investor has paid the exercise price and
exercised, in full, the Investor's First Option, through (B) 6:00 p.m., local

shall be attached to this CEI (as such number may be adjusted pursuant to

consideration is to be paid or given upon exercise of the CEI.  Buyer and its
permitted successors and assigns are hereinafter referred to as "Holder."

          1.2 Shares To Be Issued; Reservation of Shares. The Company covenants
and agrees that all CEI Shares will,  upon  issuance,  be duly  authorized,
validly issued and outstanding, fully paid and non-assessable, and free from all
taxes,  liens and  charges  with  respect  to the  issuance  thereof,  except as
otherwise  provided in the Commitment  Agreement.  The Company further covenants
and agrees  that it will from time to time take all  actions  required to assure

CEI is at all times equal to or less than $1610.  The Company further  covenants
and agrees that, during the Exercise Period,  the Company will at all times have
authorized  and  reserved  sufficient  shares of Common Stock to provide for the

          2.  ADJUSTMENTS TO CEI RIGHTS.  ADJUSTMENTS TO OPTION RIGHTS.

          2.1  Stock Combinations.  If the Company combines all of the
outstanding Common Stock proportionately into a smaller number of shares, the
number of CEI Shares issuable to the Holder

<PAGE>

                                                                           3

effective date of such combination.

          2.2  Reorganizations. If any of the following transactions (each, a
"Special Transaction") becomes effective: (i) a capital reorganization or
reclassification of the capital stock of the Company, (ii) a consolidation or
merger of the Company with another entity or (iii) a sale or conveyance of all
or substantially all of the Company's assets, then, as a condition of any such
Special Transaction, lawful and adequate provision shall be made whereby the
Holder shall thereafter have the right to acquire and receive, at any time
after the consummation of such transaction until the expiration of the Exercise
Period, upon the basis and upon the terms and conditions specified herein, and
in lieu of the CEI Shares immediately theretofore issuable upon exercise of
this CEI, such shares of stock, other securities, cash or other assets as may
be issued or payable in and pursuant to the terms of such Special Transaction
with respect to or in exchange for a number of outstanding shares of Common
Stock equal to the number of CEI Shares immediately theretofore issuable upon
exercise in full of this CEI had such Special Transaction not taken place (pro
rated in the case of any partial exercises).  In connection with any Special
Transaction, appropriate provision will be made with respect to the rights and
interests of the Holder to the end that the provisions of this CEI (including
without limitation provisions for adjustment of the Exercise Price and the
number of CEI Shares issuable upon the exercise of the CEI), will thereafter be
applicable, as nearly as may be, to any shares of stock, other securities, cash
or other assets thereafter deliverable upon the exercise of this CEI.  The
Company will not effect any Special Transaction unless prior to or
simultaneously with the closing the successor entity (if other than the
Company), if any, resulting from such consolidation or merger or the entity
acquiring such assets assumes by a written instrument executed and mailed by
certified mail or delivered to the Holder (which instrument shall be in form
and substance reasonably satisfactory to Holder) at the address of the Holder
appearing on the books of the Company, the obligation of the Company or such
successor corporation to deliver to such Holder such shares of stock,
securities, cash or other assets as, in accordance with the foregoing
provisions, such Holder has rights to acquire.

          2.3  Adjustment Upon Changes in Capitalization. In the event of any
change in the Common Stock by reason of stock dividends, stock splits,
recapitalizations, reclassifications or

                                                                           4

the like, the type and number of CEI Shares issuable upon exercise of this CEI
will be adjusted appropriately, immediately upon such change. No such
adjustment will be made on account of any dividend payable other than in stock
of the Company.

          2.4  Notice.  Whenever this CEI or the CEI Shares is to be adjusted
     as  provided  herein or a  dividend  or  distribution  (in  cash,  stock or
otherwise and including,  without limitation,  any liquidating distributions) is
to be declared by the Company, or a Special Transaction is deemed by the Company
to be substantially  certain to occur (other than a Special Transaction in which
the Company is the surviving entity and which would not require the execution of
a written instrument  pursuant to Section 2.2 above), the Company will forthwith
cause to be sent to the Holder at the last  address  of the Holder  shown on the
books of the Company,  by first-class mail,  postage prepaid,  at least ten (10)
days prior to the record  date  specified  in (A) below or at least  twenty (20)
days before the date  specified  in (B) below,  a notice  stating in  reasonable
detail the facts  requiring such  adjustment  and the  calculation  thereof,  if
applicable, and stating (if applicable):

               (A)  the record date of such dividend, distribution, subdivision
     or  combination,  or, if a record is not to be taken,  the date as of which
the  holders  of  Common  Stock  of  record  to be  entitled  to such  dividend,
distribution, subdivision or combination are to be determined (provided, that in
the event the Company  institutes  a policy of  declaring  cash  dividends  on a
periodic basis,  the Company need only provide the relevant  information  called
for in this  clause (A) with  respect to the first cash  dividend  payment to be
made pursuant to such policy and  thereafter  provide only notice of any changes
in the amount or the frequency of any subsequent dividend payments),  or

               (B) the date on which a Special  Transaction  is expected to
become  effective,  and the date as of which it is  expected  that  holders  of
Common  Stock of record  are entitled  to  exchange  their  shares of Common
Stock for  securities  or other property deliverable upon consummation of the
Special Transaction.

          2.5  Fractional Interests. This CEI may be exercised only for a whole
number of shares of Common Stock, other than any fraction of a share of Common
Stock which would result upon this CEI being exercised in full; provided,
however that the Company is not required to issue fractions of shares of Common
Stock on the exercise in full of this CEI.  If any fraction of a share of

                                                                           5

     Common  Stock  would,  except for the  provisions  of this  Section 2.5, be
issuable  upon the  exercise  in full of this CEI,  the  Company may (in lieu of
issuing such  fractional  share) either (A) purchase such fraction for an amount
in cash equal to the current value of such fraction,  computed (i) if the Common
Stock is listed  or  admitted  to  unlisted  trading  privileges  on the  NASDAQ
National  Market  System or any  securities  exchange,  on the basis of the last
reported  sale price of the Common Stock on such  exchange on the last  business
day  prior to the date of  exercise  upon  which  such a sale  shall  have  been
effected  (or,  if the Common  Stock  shall be listed or  admitted  to  unlisted
trading privileges on more than one such exchange, on the basis of such price on
the  exchange  designated  from  time to time for such  purpose  by the Board of
Directors  of the  Company)  or (ii) if the  Common  Stock is not so  listed  or
admitted to unlisted trading privileges,  on the basis of the last bid price, or
if there is no reported last bid, the average of the bid prices,  for the Common
Stock on the last business day prior to the date of exercise, as reported by the
National  Association of Securities  Dealers  Automated  Quotation System or any
successor thereto, or, if such computations cannot be made as aforesaid,  as the
Board of  Directors  of the Company may in good faith  determine  or (B) issue a
number of whole shares determined by rounding up to the nearest whole share.

          3.  EXERCISE.

          3.1  Exercise of this CEI. Subject to compliance with federal and
     state securities laws and to Section 1.1, the Holder may exercise this CEI,
in whole or in part, at any time during the Exercise Period by surrendering this
CEI,  with the form of  exercise  notice  attached  hereto as  Exhibit  "A" duly
executed by Holder.  Upon any partial exercise of this CEI, the Company,  at its
expense,  will  forthwith  issue to the  Holder for this CEI a  replacement  CEI
identical  in all  respects  to this CEI,  except  that the number of CEI Shares
shall be reduced accordingly.

          3.2  Issuance of CEI Shares. The CEI Shares acquired will be issued
     to the Holder  exercising  this CEI as of the close of business on the date
on which all actions  required to be taken by Holder,  pursuant to Section  3.1,
have been taken.  Certificates for the CEI Shares so purchased will be delivered
to the Holder within a reasonable  time,  not exceeding ten (10) days after this
CEI is surrendered.

          4.  NO DILUTION OR IMPAIRMENT.  The Company will not, by amendment
     of its Certificate of  Incorporation  or Bylaws or through  reorganization,
reclassification,  consolidation,  merger,  dissolution,  sale of  assets or any
other voluntary action,  avoid or seek to avoid the observance or performance of
any of the terms of this CEI,  but will at all times in good faith assist in the
carrying  out of all such terms and in the  taking of all such  action as may be
necessary or  appropriate  in order to protect the rights of the Holder  against
dilution or other impairment.  Without limiting the generality of the foregoing,
the  Company  will not  increase  the par value of any  shares  of Common  Stock
receivable  upon the exercise of this CEI above the Exercise  Price,  and at all
times will take all such action as may be necessary or appropriate in order that
the Company may validly and legally issue fully paid and  non-assessable  shares
of Common  Stock upon the  exercise of this CEI. In the event of actions,  other
than those specified herein,  affecting  adversely the rights of the Holder, the
Board of  Directors  of the  Company  will  make  such  adjustments  as shall be
equitable in the circumstances to preserve for Holder the benefits of this CEI.

          5.  RIGHTS OF HOLDER.  Holder is not, solely by virtue of this CEI
and prior to the issuance of the CEI Shares upon due exercise thereof, entitled
to any rights of a stockholder in the Company.

          6.  TRANSFERABILITY. Holder may not sell, assign, transfer or
     otherwise  dispose of this CEI,  except in accordance with the terms of the
Commitment  Agreement.  Subject to compliance with federal and state  securities
laws and with the  Commitment  Agreement,  if  applicable,  the Holder may sell,
assign,  transfer  or  otherwise  dispose  of any CEI Shares  acquired  upon any
exercise hereof at any time and from time to time.

          7.  LEGEND ON CEI SHARES. Certificates evidencing the CEI Shares
     will  bear  the  following  legend:  "THE  SECURITIES  REPRESENTED  BY THIS
CERTIFICATE OR INSTRUMENT HAVE NOT BEEN  REGISTERED  UNDER THE SECURITIES ACT OF

                          CONTINGENT EQUITY INSTRUMENT

          This CONTINGENT EQUITY INSTRUMENT (the "CEI") is dated as of June 16,
1997, by and between Nextel Communications, Inc., a Delaware corporation (the
"Company") and Digital Radio, L.L.C., a Washington limited liability company
("Buyer").  Capitalized terms used herein and not otherwise defined herein
shall have the meanings ascribed to them in the Commitment Agreement (as
defined below).

                                   RECITALS

          The Company and Buyer have entered into an Option Exercise and
Lending Commitment Agreement dated as of June 16, 1997 (the "Commitment
Agreement") pursuant to which, among other things, Seller agreed to sell, and
Buyer agreed to purchase this CEI, which, under certain circumstances, entitles
Buyer to acquire shares of the Company's Class A Common Stock, par value $.001
per share (the "Common Stock"), on the terms set forth in this CEI.

                                                                           2

                                    AGREEMENT

          NOW, THEREFORE, for the consideration set forth in the Commitment
Agreement, $1,610.00 paid to the Company upon the execution and delivery of
this CEI, and other good and valuable consideration, the sufficiency and
receipt of which is hereby acknowledged, the Company agrees with Buyer as
follows:

          1. GRANT OF CEI.

          1.1  Grant.  The Company hereby grants to Buyer this CEI, exercisable
as provided herein in whole or in part at any time and from time to time during
the period from (A) the date that Investor has paid the exercise price and
exercised, in full, the Investor's First Option, through (B) 6:00 p.m., local
time in New York, New York, on July 28, 1999 (the "Exercise Period") to acquire
the number of shares of Common Stock determined at the Closing in accordance
with Section 1.3 of the Commitment Agreement (as set forth in the instrument
executed pursuant to Section 1.5(a)(ii) of the Commitment Agreement which is or
shall be attached to this CEI (as such number may be adjusted pursuant to
Section 2 hereof, the "CEI Shares")).  No additional payment or other
consideration is to be paid or given upon exercise of the CEI.  Buyer and its
permitted successors and assigns are hereinafter referred to as "Holder."

          1.2 Shares To Be Issued; Reservation of Shares. The Company covenants
and agrees that all CEI Shares will,  upon  issuance,  be duly  authorized,
validly issued and outstanding, fully paid and non-assessable, and free from all
taxes,  liens and  charges  with  respect  to the  issuance  thereof,  except as
otherwise  provided in the Commitment  Agreement.  The Company further covenants
and agrees  that it will from time to time take all  actions  required to assure
that the aggregate par value of the Common Stock  issuable upon exercise of this
CEI is at all times equal to or less than $1610.  The Company further  covenants
and agrees that, during the Exercise Period,  the Company will at all times have
authorized  and  reserved  sufficient  shares of Common Stock to provide for the
exercise of this CEI in full.

          2.  ADJUSTMENTS TO CEI RIGHTS.  ADJUSTMENTS TO OPTION RIGHTS.

          2.1  Stock Combinations.  If the Company combines all of the
outstanding Common Stock proportionately into a smaller number of shares, the
number of CEI Shares issuable to the Holder

cei.doc

<PAGE>

                                                                           3

upon exercise of this CEI will be proportionately decreased, as of the
effective date of such combination.

          2.2  Reorganizations. If any of the following transactions (each, a
"Special Transaction") becomes effective: (i) a capital reorganization or
reclassification of the capital stock of the Company, (ii) a consolidation or
merger of the Company with another entity or (iii) a sale or conveyance of all
or substantially all of the Company's assets, then, as a condition of any such
Special Transaction, lawful and adequate provision shall be made whereby the
Holder shall thereafter have the right to acquire and receive, at any time
after the consummation of such transaction until the expiration of the Exercise
Period, upon the basis and upon the terms and conditions specified herein, and
in lieu of the CEI Shares immediately theretofore issuable upon exercise of
this CEI, such shares of stock, other securities, cash or other assets as may
be issued or payable in and pursuant to the terms of such Special Transaction
with respect to or in exchange for a number of outstanding shares of Common
Stock equal to the number of CEI Shares immediately theretofore issuable upon
exercise in full of this CEI had such Special Transaction not taken place (pro
rated in the case of any partial exercises).  In connection with any Special
Transaction, appropriate provision will be made with respect to the rights and
interests of the Holder to the end that the provisions of this CEI (including
without limitation provisions for adjustment of the Exercise Price and the
number of CEI Shares issuable upon the exercise of the CEI), will thereafter be
applicable, as nearly as may be, to any shares of stock, other securities, cash
or other assets thereafter deliverable upon the exercise of this CEI.  The
Company will not effect any Special Transaction unless prior to or
simultaneously with the closing the successor entity (if other than the
Company), if any, resulting from such consolidation or merger or the entity
acquiring such assets assumes by a written instrument executed and mailed by
certified mail or delivered to the Holder (which instrument shall be in form
and substance reasonably satisfactory to Holder) at the address of the Holder
appearing on the books of the Company, the obligation of the Company or such
successor corporation to deliver to such Holder such shares of stock,
securities, cash or other assets as, in accordance with the foregoing
provisions, such Holder has rights to acquire.

                                                                           4

the like, the type and number of CEI Shares issuable upon exercise of this CEI
will be adjusted appropriately, immediately upon such change. No such
adjustment will be made on account of any dividend payable other than in stock
of the Company.

          2.4  Notice.  Whenever this CEI or the CEI Shares is to be adjusted
     as  provided  herein or a  dividend  or  distribution  (in  cash,  stock or
otherwise and including,  without limitation,  any liquidating distributions) is
to be declared by the Company, or a Special Transaction is deemed by the Company
to be substantially  certain to occur (other than a Special Transaction in which
the Company is the surviving entity and which would not require the execution of
a written instrument  pursuant to Section 2.2 above), the Company will forthwith
cause to be sent to the Holder at the last  address  of the Holder  shown on the
books of the Company,  by first-class mail,  postage prepaid,  at least ten (10)
days prior to the record  date  specified  in (A) below or at least  twenty (20)
days before the date  specified  in (B) below,  a notice  stating in  reasonable
detail the facts  requiring such  adjustment  and the  calculation  thereof,  if
applicable, and stating (if applicable):

               (A)  the record date of such dividend, distribution, subdivision
     or  combination,  or, if a record is not to be taken,  the date as of which
the  holders  of  Common  Stock  of  record  to be  entitled  to such  dividend,
distribution, subdivision or combination are to be determined (provided, that in
the event the Company  institutes  a policy of  declaring  cash  dividends  on a
periodic basis,  the Company need only provide the relevant  information  called
for in this  clause (A) with  respect to the first cash  dividend  payment to be
made pursuant to such policy and  thereafter  provide only notice of any changes
in the amount or the frequency of any subsequent dividend payments),  or

               (B) the date on which a Special  Transaction  is expected to
become  effective,  and the date as of which it is  expected  that  holders  of
Common  Stock of record  are entitled  to  exchange  their  shares of Common
Stock for  securities  or other property deliverable upon consummation of the
Special Transaction.

          2.5  Fractional Interests. This CEI may be exercised only for a whole
number of shares of Common Stock, other than any fraction of a share of Common
Stock which would result upon this CEI being exercised in full; provided,
however that the Company is not required to issue fractions of shares of Common
Stock on the exercise in full of this CEI.  If any fraction of a share of

                                                                           5

     Common  Stock  would,  except for the  provisions  of this  Section 2.5, be
issuable  upon the  exercise  in full of this CEI,  the  Company may (in lieu of
issuing such  fractional  share) either (A) purchase such fraction for an amount
in cash equal to the current value of such fraction,  computed (i) if the Common
Stock is listed  or  admitted  to  unlisted  trading  privileges  on the  NASDAQ
National  Market  System or any  securities  exchange,  on the basis of the last
reported  sale price of the Common Stock on such  exchange on the last  business
day  prior to the date of  exercise  upon  which  such a sale  shall  have  been
effected  (or,  if the Common  Stock  shall be listed or  admitted  to  unlisted
trading privileges on more than one such exchange, on the basis of such price on
the  exchange  designated  from  time to time for such  purpose  by the Board of
Directors  of the  Company)  or (ii) if the  Common  Stock is not so  listed  or
admitted to unlisted trading privileges,  on the basis of the last bid price, or
if there is no reported last bid, the average of the bid prices,  for the Common
Stock on the last business day prior to the date of exercise, as reported by the
National  Association of Securities  Dealers  Automated  Quotation System or any
successor thereto, or, if such computations cannot be made as aforesaid,  as the
Board of  Directors  of the Company may in good faith  determine  or (B) issue a
number of whole shares determined by rounding up to the nearest whole share.

          3.  EXERCISE.

          3.1  Exercise of this CEI. Subject to compliance with federal and
     state securities laws and to Section 1.1, the Holder may exercise this CEI,
in whole or in part, at any time during the Exercise Period by surrendering this
CEI,  with the form of  exercise  notice  attached  hereto as  Exhibit  "A" duly
executed by Holder.  Upon any partial exercise of this CEI, the Company,  at its
expense,  will  forthwith  issue to the  Holder for this CEI a  replacement  CEI
identical  in all  respects  to this CEI,  except  that the number of CEI Shares
shall be reduced accordingly.

          3.2  Issuance of CEI Shares. The CEI Shares acquired will be issued
     to the Holder  exercising  this CEI as of the close of business on the date
on which all actions  required to be taken by Holder,  pursuant to Section  3.1,
have been taken.  Certificates for the CEI Shares so purchased will be delivered
to the Holder within a reasonable  time,  not exceeding ten (10) days after this
CEI is surrendered.

          4.  NO DILUTION OR IMPAIRMENT.  The Company will not, by amendment
     of its Certificate of  Incorporation  or Bylaws or through  reorganization,
reclassification,  consolidation,  merger,  dissolution,  sale of  assets or any
other voluntary action,  avoid or seek to avoid the observance or performance of
any of the terms of this CEI,  but will at all times in good faith assist in the
carrying  out of all such terms and in the  taking of all such  action as may be
necessary or  appropriate  in order to protect the rights of the Holder  against
dilution or other impairment.  Without limiting the generality of the foregoing,
the  Company  will not  increase  the par value of any  shares  of Common  Stock
receivable  upon the exercise of this CEI above the Exercise  Price,  and at all
times will take all such action as may be necessary or appropriate in order that
the Company may validly and legally issue fully paid and  non-assessable  shares
of Common  Stock upon the  exercise of this CEI. In the event of actions,  other
than those specified herein,  affecting  adversely the rights of the Holder, the
Board of  Directors  of the  Company  will  make  such  adjustments  as shall be
equitable in the circumstances to preserve for Holder the benefits of this CEI.

          5.  RIGHTS OF HOLDER.  Holder is not, solely by virtue of this CEI
and prior to the issuance of the CEI Shares upon due exercise thereof, entitled
to any rights of a stockholder in the Company.

          6.  TRANSFERABILITY. Holder may not sell, assign, transfer or
     otherwise  dispose of this CEI,  except in accordance with the terms of the
Commitment  Agreement.  Subject to compliance with federal and state  securities
laws and with the  Commitment  Agreement,  if  applicable,  the Holder may sell,
assign,  transfer  or  otherwise  dispose  of any CEI Shares  acquired  upon any
exercise hereof at any time and from time to time.

          7.  LEGEND ON CEI SHARES. Certificates evidencing the CEI Shares
     will  bear  the  following  legend:  "THE  SECURITIES  REPRESENTED  BY THIS
CERTIFICATE OR INSTRUMENT HAVE NOT BEEN  REGISTERED  UNDER THE SECURITIES ACT OF
1933, AS AMENDED (THE "ACT"),  OR UNDER ANY APPLICABLE STATE LAWS AND MAY NOT BE

                             PURCHASE AGREEMENT

          This Option Purchase Agreement (this "Agreement") is entered into as
of June 16, 1997, by and among Nextel Communications, Inc., a Delaware
corporation (the "Company"), Unrestricted Subsidiary Funding Company, a
Delaware corporation and a wholly owned subsidiary of the Company ("USFC"),
and Option Acquisition, L.L.C., a Washington limited liability company
("Option Acquisition").

          Unless the context otherwise requires, terms capitalized and not
otherwise defined in context have the meanings set forth or cross-referenced in
Article 9 of this Agreement.

                                 Recitals

          On March 21, 1997, USFC paid $25 million to acquire from an affiliate
of Comcast Corporation options held by the Comcast affiliate to acquire 25
million shares of Common Stock (the "Comcast Options").

          Option Acquisition wishes to enter into a transaction with the
Company and USFC in which Option Acquisition would obtain from USFC the Comcast
Options, which would in turn be exchanged for two new options from the Company
entitling Option Acquisition to acquire 25 million shares of Common Stock, as
more fully set forth herein.

          Option Acquisition is controlled by Craig O. McCaw ("Individual").

          Simultaneously with the execution and delivery of this Agreement,
Digital Radio, L.L.C., a Washington limited liability company ("Investor")
controlled by Individual, is entering into an agreement by which Investor is
committing to exercise an

CLCORP01 Doc: 229734_4                     1

<PAGE>

option it holds to purchase Common Stock and Investor is committing, subject to
certain terms and conditions, to loan up to $50 million to affiliates of the
Company.

                                  Agreement

          NOW THEREFORE, in consideration of the recitals and the mutual
covenants of this Agreement, the parties agree:

          1.2  Exchange of Comcast Options. At the Closing, upon delivery of
the Comcast Options by USFC to Option Acquisition pursuant to Section 1.1,
Option Acquisition will thereupon deliver the Comcast Options to the Company
(together with appropriate instruments assigning the Comcast Options to the
Company) in exchange for the issuance of the Options described in Section 1.3.

          1.3  Issuance of New Options. At the Closing, in exchange for the

          1.5  Adjustment Upon the Occurrence of Certain Events.  Prior to the
Closing, the First New Option and the Second New Option (the "New Options") are
subject to adjustment from time to time as follows:

          (a)  If the Company at any time prior to the Closing declares a
dividend or makes any  distribution  on its Common Stock  payable in Common
Stock, or subdivides,  combines or consolidates its outstanding shares of Common
Stock,  the Company  shall notify Option  Acquisition  of such event and (i) the
number of  shares  of  Common  Stock  purchasable  under  the New  Options  (the
"Reserved  Common  Shares")  shall be  adjusted  by  multiplying  the  number of
Reserved Common Shares  immediately prior to such event by a fraction,  of which
the  numerator  shall be the  number  of  outstanding  shares  of  Common  Stock
immediately  following  such  event and the  denominator  shall be the number of
outstanding shares of Common Stock immediately prior to such event, and (ii) the
exercise  price for each Reserved  Common Share  purchasable  under a New Option
shall be  adjusted  by  multiplying  such  price  by a  fraction,  of which  the
numerator  is one and the  denominator  is the fraction  determined  pursuant to
clause (i) above. Such adjustments will become effective  immediately  following
the record date for  determination of the stockholders  entitled to receive such
dividend  or  distribution  in  the  case  of  a  dividend  or  distribution  or
immediately  after the effective date in the case of a subdivision,  combination
or consolidation.

          (b) If the Company at any time prior to the Closing reclassifies or
otherwise  changes its  outstanding  shares of Common  Stock  (other than a
change  in par  value,  or from par  value to no par  value,  or a  subdivision,
combination or consolidation referred to in Section 1.5(a)) or if the Company at
any time  prior to the  Closing  merges or  consolidates  with or into any other
corporation  (other  than a  merger  in  which  the  Company  is  the  surviving
corporation and in connection with which there is no  reclassification  or other
change of Common Stock or any issuance of stock,  securities  or property to the
holders of the Company's  outstanding shares of Common Stock),  then the Company

change,  merger or  consolidation,  each Reserved Common Share purchasable under
the New  Options  shall be deemed to  consist  solely of the kind and  amount of

the  consolidated  financial  position  of  the  Company  and  its  consolidated
Subsidiaries  as of March 31,  1997,  and each of the other  related  statements
included in such Company  Financial  Statements  present fairly, in all material

investment banker, broker, finder, consultant or intermediary in connection with
the  transactions  contemplated by this Agreement which would be entitled to any
investment  banking,  brokerage,  finder's  or  similar  fee  or  commission  in
connection with this Agreement or the transactions contemplated hereby.

          3.9 Permitted Assumptions.  Each of the representations and
warranties above that are identified as being made "based on the Permitted

effect on (X) the Business  Condition of the Company and its Subsidiaries  taken

consents,  approvals  or  waivers of any  other  Person  necessary  for  Option
Acquisition  or such Affiliate to perform its obligations  under this Agreement
and the  Transaction Agreements at or prior  to the  Closing,  and no  further
Authorizations  or consents,  approvals  or  waivers of any other  Persons  are

actions as may be necessary or appropriate  to effectuate,  carry out and comply
with all of the terms of each of the  Transaction  Agreements to which it or any
of its Affiliates is a party and the transactions  contemplated thereby. Without
limiting  the  generality  of the  preceding  sentence,  the  Company and Option
Acquisition shall not (and shall not permit their Affiliates to) take any action
or actions at or prior to the Closing that would (a) cause any  Authorization or

given or  obtained  in  connection  with the  Transactions  to be  withdrawn  or
terminated  or to otherwise  cease to be effective,  (b) require any  additional

          (THE "ACT"),  OR UNDER ANY APPLICABLE STATE LAWS AND MAY NOT BE

          EFFECTIVE  REGISTRATION UNDER THE ACT OR SUCH LAWS OR AN OPINION OF
          COUNSEL REASONABLY SATISFACTORY TO THE COMPANY THAT SUCH
          REGISTRATION IS NOT REQUIRED UNDER THE ACT OR SUCH LAWS AND THE RULES
          AND REGULATIONS PROMULGATED THEREUNDER.

          THE SECURITIES REPRESENTED BY THIS CERTIFICATE OR INSTRUMENT ARE
          SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER AND VOTING AS SET FORTH
          IN THE OPTION PURCHASE AGREEMENT, DATED AS OF JUNE 16, 1997, A COPY
          OF WHICH IS ON FILE AT THE PRINCIPAL EXECUTIVE OFFICES OF THE
          COMPANY. ANY REGISTRATION OF TRANSFER OF SUCH SECURITIES ON THE BOOKS
          OF THE COMPANY WILL BE SUBJECT TO COMPLIANCE WITH SUCH RESTRICTIONS.


                                 OPTION AGREEMENT
                                (First New Option)

          This OPTION AGREEMENT (First New Option) (the "Option") is dated
               , 1997, by and between Nextel Communications, Inc., a Delaware
corporation (the "Company") and Option Acquisition, L.L.C., a Washington
limited liability company ("Buyer").  Capitalized terms used herein and not
otherwise defined herein shall have the meanings ascribed to them in the Option
Purchase Agreement (as defined below).

                                RECITALS

          The Company, Buyer and Unrestricted Subsidiary Funding Company, a
Delaware corporation and a wholly owned subsidiary of the Company ("USFC"),
have entered into an Option Purchase

<PAGE>

                                                                           2

Agreement dated as of June 16, 1997 (the "Option Purchase Agreement") pursuant
to which, among other things, the Buyer agreed to purchase from USFC certain
options (the "Old Options") to acquire up to 25,000,000 shares of the Company's
Class A Common Stock, par value $.001 per share (the "Common Stock") and the
Buyer and the Company agreed to exchange the Old Options for two options to
purchase shares of Common Stock, on the terms set forth in the Option Purchase
Agreement, this Option, and the Second New Option.

           An affiliate of Buyer, Digital Radio, L.L.C. ("Investor"), is a
stockholder of the Company and holds an Option Agreement (First Tranche) issued
by the Company to Investor on July 28, 1995 (the "Investor's First Option") to
purchase Common Stock of the Company.

                                 AGREEMENT

          NOW, THEREFORE, for the consideration set forth in the Option
Purchase Agreement and other good and valuable consideration, the sufficiency
and receipt of which is hereby acknowledged, the Company agrees with Buyer as
follows:

          1. GRANT OF OPTION.

          1.1  Grant.  The Company hereby grants to Buyer this Option,
exercisable  as  provided  herein  in whole or in part at any time and from
time to time  during the period from  (A) the  date that  Investor  has paid the
exercise price and exercised,  in full,  the  Investor's  First Option,  through
(B) 6:00 p.m., local time in New York, New York, on July 28, 1998 (the "Exercise
Period") to purchase an aggregate of up to Fifteen Million  (15,000,000)  shares
of Common  Stock (as such number may be  adjusted  pursuant to Section 2 hereof,
the "Option  Shares"),  at an exercise  price of $16.00 per share (as such price
may be adjusted pursuant to Section 2 hereof, the "Exercise  Price").  Buyer and
its permitted successors and assigns are hereinafter referred to as "Holder."

          1.2  Shares To Be Issued; Reservation of Shares.  The Company
covenants and agrees that all Option Shares will, upon issuance, be duly
authorized, validly issued and outstanding, fully paid and non-assessable, and
free from all taxes, liens and charges with respect to the issuance thereof,
except as otherwise provided in the Option Purchase Agreement.  The Company
further

CLCORP01 Doc: 229672_4

                                                                           3

<PAGE>

covenants and agrees that it will from time to time take all actions required
to assure that the par value per share of the Common Stock is at all times
equal to or less than the effective Exercise Price.  The Company further
covenants and agrees that, during the Exercise Period, the Company will at all
times have authorized and reserved sufficient shares of Common Stock to provide
for the exercise of this Option in full.

          2. ADJUSTMENTS TO OPTION RIGHTS.

          2.1 Stock Combinations. If the Company combines all of the
outstanding Common Stock  proportionately  into a smaller number of shares,
the Exercise  Price per Option Share  hereunder in effect  immediately  prior to
such  combination  will be  proportionately  increased  and the number of Option
Shares   issuable  to  the  Holder   upon   exercise  of  this  Option  will  be
proportionately decreased, as of the effective date of such combination.

          2.2  Reorganizations.  If any of the following transactions (each, a
"Special  Transaction") becomes effective:  (i) a capital reorganization or
reclassification  of the capital stock of the Company,  (ii) a consolidation  or
merger of the Company with another  entity or (iii) a sale or  conveyance of all
or substantially all of the Company's  assets,  then, as a condition of any such
Special  Transaction,  lawful and adequate  provision  shall be made whereby the
Holder shall  thereafter  have the right to purchase  and  receive,  at any time
after the consummation of such transaction  until the expiration of the Exercise
Period,  upon the basis and upon the terms and conditions  specified herein, and
in lieu of the Option Shares immediately  theretofore  issuable upon exercise of
this Option for the aggregate Exercise Price in effect immediately prior to such
consummation,  such shares of stock,  other securities,  cash or other assets as
may be  issued  or  payable  in  and  pursuant  to the  terms  of  such  Special
Transaction with respect to or in exchange for a number of outstanding shares of
Common  Stock  equal to the  number of  Option  Shares  immediately  theretofore
issuable upon exercise in full of this Option had such Special  Transaction  not
taken place (pro rated in the case of any partial exercises). In connection with
any Special Transaction,  appropriate provision will be made with respect to the
rights and interests of the Holder to the end that the provisions of this Option
(including  without  limitation  provisions for adjustment of the Exercise

CLCORP01 Doc: 229672_4

<PAGE>

                                                                           4

Price and the number of Option  Shares  issuable  upon the  exercise of the
Option),  will  thereafter be applicable,  as nearly as may be, to any shares of
stock,  other securities,  cash or other assets thereafter  deliverable upon the
exercise of this  Option.  The Company  will not effect any Special  Transaction
unless  prior to or  simultaneously  with the closing the  successor  entity (if
other than the Company),  if any, resulting from such consolidation or merger or
the entity  acquiring such assets assumes by a written  instrument  executed and
mailed by certified mail or delivered to the Holder (which  instrument  shall be
in form and substance  reasonably  satisfactory to Holder) at the address of the
Holder  appearing on the books of the Company,  the obligation of the Company or
such  successor  corporation  to deliver to such  Holder  such  shares of stock,
securities,   cash  or  other  assets  as,  in  accordance  with  the  foregoing
provisions, such Holder has rights to purchase.

          2.3  Adjustment Upon Changes in Capitalization.  In the event of any
change in the  Common  Stock by reason of stock  dividends,  stock  splits,
recapitalizations,  reclassifications or the like, the type and number of Option
Shares  issuable upon exercise of this Option,  and the Exercise  Price,  as the
case may be, will be adjusted  appropriately,  immediately upon such change.  No
such  adjustment  will be made on account of any dividend  payable other than in
stock of the Company.

          2.4  Notice.  Whenever this Option, the Option Shares or the Exercise
Price is to be adjusted as  provided  herein or a dividend or  distribution
(in cash, stock or otherwise and including,  without limitation, any liquidating
distributions)  is to be declared by the Company,  or a Special  Transaction  is
deemed by the Company to be substantially certain to occur (other than a Special
Transaction  in which the  Company is the  surviving  entity and which would not
require the execution of a written  instrument  pursuant to Section 2.2  above),
the Company will forthwith cause to be sent to the Holder at the last address of
the Holder  shown on the books of the  Company,  by  first-class  mail,  postage
prepaid,  at least ten (10) days prior to the record date specified in (A) below
or at least twenty (20) days before the date  specified  in (B) below,  a notice
stating  in  reasonable  detail  the facts  requiring  such  adjustment  and the
calculation thereof, if applicable, and stating (if applicable):

                                                                           5

          (A) the record date of such dividend, distribution, subdivision or
combination,  or, if a record is not to be taken,  the date as of which the
holders of Common Stock of record to be entitled to such dividend, distribution,
subdivision or combination are to be determined (provided, that in the event the
Company institutes a policy of declaring cash dividends on a periodic basis, the
Company need only provide the relevant information called for in this clause (A)
with  respect to the first cash  dividend  payment to be made  pursuant  to such
policy and  thereafter  provide  only notice of any changes in the amount or the
frequency of any subsequent dividend payments), or

          (B) the date on which a Special Transaction is expected to become
effective, and the date as of which it is expected that holders of Common Stock
of record are entitled to exchange their shares of Common Stock for securities
or other property deliverable upon consummation of the Special Transaction.

          2.5  Fractional Interests.  This Option may be exercised only for a
whole number of shares of Common Stock,  other than any fraction of a share
of Common  Stock which would  result upon this Option  being  exercised in full;
provided,  however that the Company is not required to issue fractions of shares
of Common  Stock on the  exercise in full of this  Option.  If any fraction of a
share of Common Stock would,  except for the  provisions of this Section 2.5, be
issuable  upon the exercise in full of this Option,  the Company may (in lieu of
issuing such  fractional  share) either (A) purchase such fraction for an amount
in cash equal to the current value of such fraction,  computed (i) if the Common
Stock is listed  or  admitted  to  unlisted  trading  privileges  on the  NASDAQ
National  Market  System or any  securities  exchange,  on the basis of the last
reported  sale price of the Common Stock on such  exchange on the last  business
day  prior to the date of  exercise  upon  which  such a sale  shall  have  been
effected  (or,  if the Common  Stock  shall be listed or  admitted  to  unlisted
trading privileges on more than one such exchange, on the basis of such price on
the  exchange  designated  from  time to time for such  purpose  by the Board of
Directors  of the  Company)  or (ii) if the  Common  Stock is not so  listed  or
admitted to unlisted trading privileges,  on the basis of the last bid price, or
if there is no reported last bid, the average of the bid prices,  for the Common
Stock on the last business day prior to the date of exercise, as reported by the
National  Association of

Securities  Dealers  Automated  Quotation System or any successor thereto, or,
if such computations cannot be made as aforesaid, as the Board of  Directors of
the Company may in good faith  determine  or (B) issue a number of whole shares
determined by rounding up to the nearest whole share.

          3.  EXERCISE.

          3.1  Exercise of Option. Subject to compliance with federal and state
securities laws and to Section 1.1, the Holder may exercise this Option, in
whole or in part,  at any time during the  Exercise  Period by (i)  surrendering
this Option,  with the form of exercise  notice  attached  hereto as Exhibit "A"
duly  executed  by Holder,  and (ii) either  electing  cashless  exercise  under
Section 3.2 or making payment to the Company of the aggregate Exercise Price for
the  applicable  Option Shares by wire transfer to an account  designated by the
Company.  Upon any partial exercise of this Option, the Company, at its expense,
will  forthwith  issue to the  Holder  for  this  option  a  replacement  Option
identical  in all  respects  to this  Option,  except  that the number of Option
Shares shall be reduced accordingly.

          3.2  Cashless Exercise.  Instead of making payment under Section
3.1(ii) this Option may be exercised on a net basis, such that,  without an
exchange of any funds,  the Holder  receives  upon exercise the number of shares
designated  on the  exercise  notice less that number of shares of Common  Stock
having an aggregate  value  computed on the basis of the Average Market Price at
the time of  exercise  equal to  Exercise  Price for the  shares so  designated.
"Average  Market Price" means the arithmetic  average of the closing sales price
for a share of Common Stock on the NASDAQ-NM for the 20 trading days immediately
preceding the date on which the price is to be determined.

          3.3  Issuance of Option Shares.  The Option Shares purchased will
be issued to the Holder  exercising this Option as of the close of business
on the date on which all  actions and  payments  required to be taken or made by
Holder,  pursuant to Section 3.1, have been taken or made.  Certificates for the
Option  Shares so purchased  will be delivered to the Holder within a reasonable
time, not exceeding ten (10) days after this Option is surrendered.

          4. NO DILUTION OR IMPAIRMENT.  The Company will not, by amendment
of its Certificate of  Incorporation  or Bylaws or through  reorganization,
reclassification,  consolidation,  merger,  dissolution,  sale of  assets or any
other voluntary action,  avoid or seek to avoid the observance or performance of
any of the terms of this  Option,  but will at all times in good faith assist in
the  carrying  out of all such terms and in the taking of all such action as may
be necessary or appropriate in order to protect the rights of the Holder against
dilution or other impairment.  Without limiting the generality of the foregoing,
the  Company  will not  increase  the par value of any  shares  of Common  Stock
receivable upon the exercise of this Option above the Exercise Price, and at all
times will take all such action as may be necessary or appropriate in order that
the Company may validly and legally issue fully paid and  non-assessable  shares
of Common Stock upon the exercise of this Option. In the event of actions, other
than those specified herein,  affecting  adversely the rights of the Holder, the
Board of  Directors  of the  Company  will  make  such  adjustments  as shall be
equitable  in the  circumstances  to  preserve  for Holder the  benefits of this
Option.

          5. RIGHTS OF HOLDER.  Holder is not, solely by virtue of this Option
and prior to the issuance of the Option Shares upon due exercise thereof,
entitled to any rights of a stockholder in the Company.

          6.  TRANSFERABILITY.  Holder may sell, assign, transfer or otherwise
     dispose  of this  Option  only in  accordance  with the terms of the Option
Purchase Agreement. Subject to compliance with federal and state securities laws
and with the Option  Purchase  Agreement,  if  applicable,  the Holder may sell,
assign,  transfer or otherwise  dispose of any Option  Shares  acquired upon any
exercise hereof at any time and from time to time.

          7.  LEGEND ON OPTION SHARES.  Certificates evidencing the Option
Shares will bear the following legend: "THE SECURITIES  REPRESENTED BY THIS
CERTIFICATE OR INSTRUMENT HAVE NOT BEEN  REGISTERED  UNDER THE SECURITIES ACT OF
1933, AS AMENDED (THE "ACT"),  OR UNDER ANY APPLICABLE STATE LAWS AND MAY NOT BE

                                  (Second New Option)


          This OPTION AGREEMENT (Second New Option) (the "Option") is dated
              , 1997, by and between Nextel Communications, Inc., a Delaware

                                       RECITALS

          The Company, Buyer and Unrestricted Subsidiary Funding Company, a
Delaware corporation and a wholly owned subsidiary of the Company ("USFC"),

                                                                           2

to acquire up to 25,000,000  shares of the Company's  Class A Common Stock,
par value  $.001 per share (the  "Common  Stock")  and the Buyer and the Company
agreed to exchange the Old Options for two options to purchase  shares of Common
Stock, on the terms set forth in the Option Purchase Agreement, this Option, and
the First New Option.

          An affiliate of Buyer, Digital Radio, L.L.C. ("Investor"), is a
stockholder of the Company and holds an Option Agreement (First Tranche) issued
by the Company to Investor on July 28, 1995 (the "Investor's First Option") to
purchase Common Stock of the Company.

                                AGREEMENT

          NOW, THEREFORE, for the consideration set forth in the Option
Purchase Agreement and other good and valuable consideration, the sufficiency
and receipt of which is hereby acknowledged, the Company agrees with Buyer as
follows:

          1.  GRANT OF OPTION.

          1.1  Grant.  The Company hereby grants to Buyer this Option,
exercisable  as  provided  herein  in whole or in part at any time and from
time to time  during the period from  (A) the  date that  Investor  has paid the
exercise  price and  exercised  in full the  Investor's  First  Option,  through
(B) 6:00 p.m., local time in New York, New York, on July 28, 1998 (the "Exercise
Period") to purchase an aggregate of up to  Ten Million  (10,000,000)  shares of
Common Stock (as such number may be adjusted  pursuant to Section 2 hereof,  the
"Option Shares"), at an exercise price of $18.00 per share (as such price may be
adjusted  pursuant to Section 2 hereof,  the  "Exercise  Price").  Buyer and its
permitted successors and assigns are hereinafter referred to as "Holder."

          1.2  Shares To Be Issued; Reservation of Shares.  The Company
covenants and agrees that all Option Shares will, upon issuance, be duly
authorized, validly issued and outstanding, fully paid and non-assessable, and
free from all taxes, liens and charges with respect to the issuance thereof,
except as otherwise

CLCORP01 Doc:229875_4

<PAGE>

                                                                           3

provided in the Option Purchase  Agreement.  The Company further  covenants
and agrees  that it will from time to time take all  actions  required to assure
that the par  value per share of the  Common  Stock is at all times  equal to or
less than the effective Exercise Price. The Company further covenants and agrees
that, during the Exercise Period,  the Company will at all times have authorized
and  reserved  sufficient  shares of Common Stock to provide for the exercise of
this Option in full.

          2. ADJUSTMENTS TO OPTION RIGHTS.

          2.1  Stock Combinations.  If the Company combines all of the
outstanding Common Stock proportionately into a smaller number of shares, the
Exercise Price per Option Share hereunder in effect immediately prior to such
combination will be proportionately increased and the number of Option Shares
issuable to the Holder upon exercise of this Option will be proportionately
decreased, as of the effective date of such combination.

          2.2 Reorganizations.  If any of the following transactions (each, a
     "Special  Transaction") becomes effective:  (i) a capital reorganization or
reclassification  of the capital stock of the Company,  (ii) a consolidation  or
merger of the Company with another  entity or (iii) a sale or  conveyance of all
or substantially all of the Company's  assets,  then, as a condition of any such
Special  Transaction,  lawful and adequate  provision  shall be made whereby the
Holder shall  thereafter  have the right to purchase  and  receive,  at any time
after the consummation of such transaction  until the expiration of the Exercise
Period,  upon the basis and upon the terms and conditions  specified herein, and
in lieu of the Option Shares immediately  theretofore  issuable upon exercise of
this Option for the aggregate Exercise Price in effect immediately prior to such
consummation,  such shares of stock,  other securities,  cash or other assets as
may be  issued  or  payable  in  and  pursuant  to the  terms  of  such  Special
Transaction with respect to or in exchange for a number of outstanding shares of
Common  Stock  equal to the  number of  Option  Shares  immediately  theretofore
issuable upon exercise in full of this Option had such Special Transaction not

CLCORP01 Doc:229875_4

<PAGE>

                                                                           4

taken place (pro rated in the case of any partial exercises). In connection
with any Special Transaction, appropriate provision will be made with respect to
the rights and  interests of the Holder to the end that the  provisions  of this
Option (including without  limitation  provisions for adjustment of the Exercise
Price and the number of Option Shares issuable upon the exercise of the Option),
will  thereafter  be  applicable,  as nearly as may be, to any  shares of stock,
other securities,  cash or other assets thereafter deliverable upon the exercise
of this Option. The Company will not effect any Special Transaction unless prior
to or  simultaneously  with the closing the successor  entity (if other than the
Company),  if any,  resulting  from such  consolidation  or merger or the entity
acquiring  such assets  assumes by a written  instrument  executed and mailed by
certified mail or delivered to the Holder (which instrument shall be in form and
substance  reasonably  satisfactory  to  Holder)  at the  address  of the Holder
appearing on the books of the  Company,  the  obligation  of the Company or such
successor   corporation  to  deliver  to  such  Holder  such  shares  of  stock,
securities,   cash  or  other  assets  as,  in  accordance  with  the  foregoing
provisions, such Holder has rights to purchase.

          2.3  Adjustment Upon Changes in Capitalization.  In the event of any
change in the  Common  Stock by reason of stock  dividends,  stock  splits,
recapitalizations,  reclassifications or the like, the type and number of Option
Shares  issuable upon exercise of this Option,  and the Exercise  Price,  as the
case may be, will be adjusted  appropriately,  immediately upon such change.  No
such  adjustment  will be made on account of any dividend  payable other than in
stock of the Company.

          2.4  Notice. Whenever this Option, the Option Shares or the Exercise
Price is to be adjusted as  provided  herein or a dividend or  distribution
(in cash, stock or otherwise and including,  without limitation, any liquidating
distributions)  is to be declared by the Company,  or a Special  Transaction  is
deemed by the Company to be substantially certain to occur (other than a Special
Transaction  in which the  Company is the  surviving  entity and which would not
require the execution of a written  instrument  pursuant to Section 2.2  above),
the Company will forthwith cause to be sent to the Holder at the last address of
the Holder shown on the books of the Company, by first-class mail, postage

                                                                           5

prepaid,  at least ten (10) days prior to the record date  specified in (A)
below or at least  twenty (20) days before the date  specified  in (B) below,  a
notice stating in reasonable  detail the facts requiring such adjustment and the
calculation thereof, if applicable, and stating (if applicable):

          (A) the record date of such dividend, distribution, subdivision or
combination,  or, if a record is not to be taken,  the date as of which the
holders of Common Stock of record to be entitled to such dividend, distribution,
subdivision or combination are to be determined (provided, that in the event the
Company institutes a policy of declaring cash dividends on a periodic basis, the
Company need only provide the relevant information called for in this clause (A)
with  respect to the first cash  dividend  payment to be made  pursuant  to such
policy and  thereafter  provide  only notice of any changes in the amount or the
frequency of any subsequent dividend payments), or

          (B)  the date on which a Special Transaction is expected to become
     effective,  and the date as of which it is expected  that holders of Common
Stock of record  are  entitled  to  exchange  their  shares of Common  Stock for
securities  or other  property  deliverable  upon  consummation  of the  Special
Transaction.

          2.5  Fractional Interests.  This Option may be exercised only for a
whole number of shares of Common Stock,  other than any fraction of a share
of Common  Stock which would  result upon this Option  being  exercised in full;
provided,  however that the Company is not required to issue fractions of shares
of Common  Stock on the  exercise in full of this  Option.  If any fraction of a
share of Common Stock would,  except for the  provisions of this Section 2.5, be
issuable  upon the exercise in full of this Option,  the Company may (in lieu of
issuing such  fractional  share) either (A) purchase such fraction for an amount
in cash equal to the current value of such fraction,  computed (i) if the Common
Stock is listed  or  admitted  to  unlisted  trading  privileges  on the  NASDAQ
National  Market  System or any  securities  exchange,  on the basis of the last
reported  sale price of the Common Stock on such  exchange on the last  business
day  prior to the date of  exercise  upon  which  such a sale  shall  have  been
effected (or, if the Common Stock shall be listed or admitted to 

CLCORP01 Doc:229875_4

<PAGE>

                                                                           6

     unlisted trading privileges on more than one such exchange, on the basis of
such price on the exchange  designated from time to time for such purpose by the
Board of  Directors of the Company) or (ii) if the Common Stock is not so listed
or admitted to unlisted trading privileges,  on the basis of the last bid price,
or if there is no reported  last bid,  the  average of the bid  prices,  for the
Common Stock on the last business day prior to the date of exercise, as reported
by the National  Association of Securities Dealers Automated Quotation System or
any successor thereto, or, if such computations cannot be made as aforesaid,  as
the Board of Directors of the Company may in good faith determine or (B) issue a
number of whole shares determined by rounding up to the nearest whole share.

          3.  EXERCISE.

          3.1  Exercise of Option. Subject to compliance with federal and state
securities laws and to Section 1.1, the Holder may exercise this Option, in
whole or in part,  at any time during the  Exercise  Period by (i)  surrendering
this Option,  with the form of exercise  notice  attached  hereto as Exhibit "A"
duly  executed  by Holder,  and (ii) either  electing  cashless  exercise  under
Section 3.2 or making payment to the Company of the aggregate Exercise Price for
the  applicable  Option Shares by wire transfer to an account  designated by the
Company.  Upon any partial exercise of this Option, the Company, at its expense,
will  forthwith  issue to the  Holder  for  this  option  a  replacement  Option
identical  in all  respects  to this  Option,  except  that the number of Option
Shares shall be reduced accordingly.

          3.2  Cashless Exercise.  Instead of making payment under Section
3.1(ii) this Option may be exercised on a net basis, such that,  without an
exchange of any funds,  the Holder  receives  upon exercise the number of shares
designated  on the  exercise  notice less that number of shares of Common  Stock
having an aggregate  value  computed on the basis of the Average Market Price at
the time of exercise  equal to the Exercise  Price for the shares so designated.
"Average  Market Price" means the arithmetic  average of the closing sales price
for a share of Common Stock on the NASDAQ-NM for the 20 trading days immediately
preceding the date on which the price is to be determined.

          3.3  Issuance of Option Shares.  The Option Shares purchased will
be issued to the Holder  exercising this Option as of the close of business
on the date on which all  actions and  payments  required to be taken or made by
Holder,  pursuant to Section 3.1, have been taken or made.  Certificates for the
Option  Shares so purchased  will be delivered to the Holder within a reasonable
time, not exceeding ten (10) days after this Option is surrendered.

amendment  of  its  Certificate  of  Incorporation  or  Bylaws  or  through
reorganization,  reclassification,  consolidation,  merger, dissolution, sale of
assets or any other voluntary  action,  avoid or seek to avoid the observance or
performance  of any of the terms of this  Option,  but will at all times in good
faith assist in the carrying out of all such terms and in the taking of all such
action as may be necessary or  appropriate in order to protect the rights of the
Holder against dilution or other impairment.  Without limiting the generality of
the  foregoing,  the Company  will not  increase  the par value of any shares of
Common  Stock  receivable  upon the  exercise of this Option  above the Exercise
Price,  and at all  times  will  take all such  action  as may be  necessary  or
appropriate  in order that the Company may validly and legally  issue fully paid
and  non-assessable  shares of Common Stock upon the exercise of this Option. In
the event of actions, other than those specified herein, affecting adversely the
rights of the  Holder,  the Board of  Directors  of the  Company  will make such
adjustments  as shall be equitable in the  circumstances  to preserve for Holder
the benefits of this Option.

          5. RIGHTS OF HOLDER.  Holder is not, solely by virtue of this Option
and prior to the issuance of the Option Shares upon due exercise thereof,
entitled to any rights of a stockholder in the Company.

          6. TRANSFERABILITY. Holder may sell, assign, transfer or otherwise
dispose  of this  Option  only in  accordance  with the terms of the Option
Purchase Agreement. Subject to compliance with federal and state securities laws
and with the Option  Purchase  Agreement,  if  applicable,  the Holder may sell,
assign,  transfer or otherwise  dispose of any Option  Shares  acquired upon any
exercise hereof at any time and from time to time.

          If the Requested Registration is a Cutback  Registration, the Issuer
shall register in such  registration (1) first, the Registrable  Securities
which any Requesting Holder seeks to include in such registration, on a pro rata
basis based upon the number of such Issuer Common Shares each Requesting  Holder
seeks to include in such  registration and (2) second,  the Issuer Common Shares
held by each Electing Holder,  (i) if such Issuer Common Shares are sought to be
included in such registration pursuant to contractual  obligations of the Issuer
in existence on July 28,  1995, in accordance  with the  respective  contractual
rights of the holder of such Issuer Common Shares,  and (ii) in all other cases,
on a pro rata basis based upon the number of shares each  Electing  Holder seeks
to include in such registration.

          (b) Underwriting.  If the Requesting Holders intend to distribute the
Registrable Securities covered by such request by means of an underwriting,
such Requesting Holders shall so advise the Issuer as a part of the request made
pursuant to this Section 2.2 and, in such event,  the  Requesting  Holders shall
select an  underwriter  of their  choice,  which  choice shall be subject to the
approval of the Board of Directors of the Issuer,  and which  approval shall not
be unreasonably withheld. The Issuer and such Requesting Holders shall negotiate
in good faith and enter into an  underwriting  agreement in customary  form with
the underwriter or underwriters selected for such underwriting.  If a Requesting
Holder disapproves of the terms of the underwriting,  such Requesting Holder may
elect to withdraw  therefrom  by written  notice to the Issuer and the  managing
underwriter,  and each of the remaining  Requesting Holders shall be entitled to
increase the number of shares being  registered,  to the extent permitted by the
managing  underwriter,   in  the  proportion  which  the  number  of  shares  of
Registrable  Securities being registered by such Requesting  Holder bears to the
total  number  of  shares  being  registered  by all such  remaining  Requesting
Holders.

          2.3 Expenses of Registration.  Except as otherwise provided herein,
all expenses  incurred by the Issuer in connection with any  registration ,
qualification,  or compliance  pursuant to this  Agreement,  including,  without
limitation, all registration,  filing and qualification fees, printing expenses,
fees and  disbursements of counsel for the Issuer and the holders of Registrable
Securities, and the expenses of any audits required by such registration,  shall
be borne by the  Issuer.  However,  (a) the Issuer  shall not be required to pay
underwriters' fees, discounts or commissions relating to Registrable  Securities
and (b) the Issuer shall not be obligated to pay the fees and  disbursements  of
more than one legal counsel to the Requesting Holders.

          2.4 Registration Procedures. (a)  In the case of each registration
effected by the Issuer  pursuant to this  Article 2, the Issuer  shall keep
each holder of Registrable  Securities included in such registration  advised in
writing as to the initiation, progress, and effective date of each registration,
qualification  and  compliance,  and, at its  expense to the extent  provided in
Section 2.3, the Issuer will:

          (i) subject to Section 2.4(b) below, keep each registration effective
     for a period of 90 days (plus any number of

CLCORP01 Doc: 230115_4                 11

<PAGE>

     days that the Qualified Holders are unable to use a prospectus pursuant to
     Section 2.4(b) below) or until each such holder shall have completed the
     distribution described in the registration statement relating thereto,
     whichever first occurs (the "Registration Period"); and

          (ii) furnish such number of prospectuses (including preliminary
     prospectuses) and other documents filed with the Securities and Exchange
     Commission (the "Commission") as part of the registration statement as
     such holders from time to time may request.

          (b) If, within the Registration Period, there occurs any development
or any event which makes any statement in the registration statement or any
post-effective  amendment  thereto,  or any  document  incorporated  therein  by
reference,  untrue in any material  respect or which  requires the making of any
changes in the registration  statement or  post-effective  amendment  thereto or
prospectus or amendment or supplement thereto, so that they will not contain any
untrue  statement of a material fact or omit to state any material fact required
to be stated therein or necessary to make the statements therein (in the case of
any prospectus,  in the light of the  circumstances  under which they

CLCORP01 Doc: 230115_4                  12

<PAGE>

were  made) not  misleading,  the  Issuer  shall  immediately  notify  each
Qualified Holder included in such registration of the occurrence thereof and, as
soon as  reasonably  practicable,  prepare  and furnish to each such  holder,  a
reasonable number of copies of a prospectus  supplemented or amended so that, as
thereafter  delivered to purchasers of Registrable  Securities,  such prospectus
shall not  contain an untrue  statement  of a  material  fact or omit to state a
material fact required to be stated  therein or necessary to make the statements
therein,  in the light of the  circumstances  under  which they were  made,  not
misleading.  Each Qualified  Holder agrees that, upon receipt of any notice from
the  Issuer  pursuant  to this  Section  2.4(b),  such  holder  shall  forthwith
discontinue  disposition of Registrable  Securities until it shall have received
copies of such amended or  supplemented  prospectus,  and, if so directed by the
Issuer,  shall  deliver to the  Issuer all  copies,  other than  permanent  file
copies, then in its possession of the prospectus covering Registrable Securities
at the time of receipt of such notice.

          (c) Each Qualified Holder participating in any Cutback Registration
shall, as among all holders of Registrable Securities, be entitled to exercise
its rights hereunder pro rata

CLCORP01 Doc: 230115_4                  13

<PAGE>

according to the number of shares of Registrable Securities held by such
Qualified Holder and any Electing Holders.

          (d) If requested by the underwriters for any underwritten offering
of Registrable  Securities pursuant to a registration  requested under this
Agreement,  the  Issuer  will  enter into an  underwriting  agreement  with such
underwriters for such offering,  such agreement to contain such  representations
and  warranties  by the  Issuer  and such  other  terms  and  provisions  as are
customarily  contained  in  underwriting  agreements  with  respect to secondary
distributions,  including,  without limitation,  indemnities and contribution to
the effect and to the extent  provided  in Section  2.5 hereof and an opinion of
counsel  for the Issuer  dated the date of the  closing  under the  underwriting
agreement, and providing that the Issuer shall use its best efforts to furnish a
"cold comfort"  letter signed by the  independent  public  accountants  who have
audited  the  Issuer's  financial   statements  included  in  such  registration
statement,  in each such  case  covering  substantially  the same  matters  with
respect to such registration  statement (and the prospectus included therein) as
are  customarily  covered in opinions of  Issuer's  counsel and in  accountants'
letters delivered to underwriters in underwritten public offerings of securities
and

CLCORP01 Doc: 230115_4                  14

<PAGE>

such other matters as the underwriters  reasonably  request and, in the case
of such  accountants'  letter,  with respect to events subsequent to the date of
such financial statements. The holders of Registrable Securities on whose behalf
the Registrable  Securities are to be distributed by such underwriters  shall be
parties to any such underwriting agreement.

          (e) In connection with the preparation and filing of each
registration   statement  registering   Registrable  Securities  under  the
Securities Act, the Issuer will give the underwriters, if any, and their counsel
and  accountants,  such reasonable and customary access to its books and records
and such  opportunities  to discuss the business of the Issuer with its officers
and the independent public accountants who have certified the Issuer's financial
statements as shall be necessary,  in the opinion of such  underwriters or their
respective counsel, to conduct a reasonable  investigation within the meaning of
the Securities Act.

          2.5 Indemnification. (a) With respect to any registration which has
been effected pursuant to this Article 2, the Issuer shall indemnify each
Qualified Holder whose securities are included therein, each such holder's
directors and officers, each underwriter (as defined in the Securities Act) of
the securities

CLCORP01 Doc: 230115_4                  15

<PAGE>

sold by such a holder,  each other Person who  participates in the offering
of such holder's securities, and each Person who controls (within the meaning of
the Securities Act) any such holder,  underwriter,  or participating Person from
and against all claims,  losses,  damages and liabilities (or actions in respect
thereof) arising out of or based on:

               (i) any untrue statement (or alleged untrue statement) of a
               material fact contained in any prospectus, offering circular or
               other document (including any related registration statement)
               incident to any such registration effected pursuant to this
               Article 2,

               (ii) any omission (or alleged omission) to state therein a
               material fact required to be stated therein or necessary to make
               the statements therein not misleading, or

               (iii) any violation by the Issuer of the Securities Act or any
               rule or regulation promulgated thereunder applicable to the
               Issuer, or any blue sky or state securities laws or any rule or
               regulation promulgated thereunder applicable to the Issuer,

in each case relating to action or inaction required of the Issuer in
connection with any such registration, and will

CLCORP01 Doc: 230115_4                  16

<PAGE>

     reimburse  each such Person  entitled to indemnity  hereunder for any legal
and other  expenses  reasonably  incurred in connection  with  investigating  or
defending any such claim, loss, damage,  liability or action; provided that, the
foregoing indemnity and reimbursement obligation is not applicable to the extent
that any such claim,  loss, damage or liability arises out of or is based on any
untrue statement (or alleged untrue statement) or omission (or alleged omission)
made in reliance upon and in conformity  with written  information  furnished to
the  Issuer  by or on  behalf  of such a holder  or by or on  behalf  of such an
underwriter specifically for use in such prospectus,  offering circular or other
document;  and further  provided that,  with respect to any untrue  statement or
omission  or  alleged  untrue  statement  or  omission  made in any  preliminary
prospectus,  the indemnity  agreement  contained in this Section 2.5(a) will not
inure to the  benefit of any  underwriter  to the extent  that any such  losses,
claims,  damages or  liabilities of such  underwriter  result from the fact that
there was not sent or given to any person who purchased  Registrable  Securities
in connection with such registration, at or prior to the written confirmation of
the sale of  Registrable  Securities  to such person,  a copy of the  prospectus
relating to such  registration,  as then amended or

CLCORP01 Doc: 230115_4                  17

<PAGE>

supplemented  (exclusive of material  incorporated  by reference),  if the
Issuer had  previously  furnished copies thereof to such underwriter.

          (b) Each holder of Registrable Securities which are included in such
registration, qualification or compliance shall indemnify the Issuer, its
directors and officers, each underwriter (as defined in the Securities Act) of
the securities of such holder, each other person who participates in the
offering of such holder's securities and each Person who controls (within the
meaning of the Securities Act) the Issuer or any such underwriter or
participating Person from and against all claims, losses, damages and
liabilities (or actions in respect thereof) arising out of or based on:

               (i) any untrue statement (or alleged untrue statement) of a
               material fact contained in any prospectus, offering circular or
               other document (including any related registration statement)
               incident to any such registration effected pursuant to this
               Article 2,

               (ii) any omission (or alleged omission) to state therein a
               material fact required to be stated therein or necessary to make
               the statements therein not misleading, or

CLCORP01 Doc: 230115_4                  18

<PAGE>

               (iii)any violation by such holder of the Securities Act or any
               rule or regulation promulgated thereunder applicable to such
               holder, or of any blue sky or other state securities law or any
               rule or regulation promulgated thereunder applicable to such
               holder,

in each case,  relating  to action or  inaction  required of such holder in
connection  with  any  registration,   qualification  or  compliance,  and  will
reimburse  each such Person  entitled to indemnity  hereunder  for any legal and
other expenses reasonably incurred in connection with investigating or defending
any such claim,  loss,  damage,  expense,  liability or action, but in each case
only to the extent that such untrue  statement (or alleged untrue  statement) or
omission (or alleged omission) is made in such prospectus,  offering circular or
other  document in reliance  upon and in  conformity  with  written  information
furnished  to the  Issuer by or on behalf of such  holder  specifically  for use
therein;  and further  provided  that,  with respect to any untrue  statement or
omission  or  alleged  untrue  statement  or  omission  made in any  preliminary
prospectus,  the indemnity  agreement  contained in this Section 2.5(b) will not
inure to the  benefit of any  underwriter  to the extent  that any such  losses,
claims,  damages or  liabilities of such  underwriter  result from the fact

CLCORP01 Doc: 230115_4                  19

<PAGE>

that there was not sent or given to any person  who  purchased  Registrable
Securities  in  connection  with such  registration,  at or prior to the written
confirmation of the sale of Registrable Securities to such person, a copy of the
prospectus  relating  to such  registration,  as then  amended  or  supplemented
(exclusive of material incorporated by reference),  if the Issuer had previously
furnished copies thereof to such underwriter.

          (c) Each party entitled to indemnification under this Section 2.5 (an
"Indemnified  Party")  shall give  notice to the party  required to provide
indemnification (the "Indemnifying  Party") promptly after the Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the  Indemnifying  Party to assume  the  defense of any such claim or any
litigation resulting  therefrom;  provided that

               (i) counsel for the Indemnifying Party who shall conduct the
     defense of any such claim or any litigation shall be approved by the
     Indemnified Party,

               (ii) the Indemnified Party may participate in such defense at
     the Indemnified Party's expense (provided that the Indemnified Party or
     Indemnified Parties have the right to employ one counsel to represent it
     or them if, in the reasonable judgment of the Indemnified Party or

CLCORP01 Doc: 230115_4                  20

<PAGE>

     Indemnified Parties, it is advisable for it or them to be represented
     by separate counsel by reason of having legal defenses which are different
     from or in addition to those available to the Indemnifying Party, and in
     that event the fees and expenses of such one counsel will be paid by
     the Indemnifying Party), and

               (iii) failure of any Indemnified Party to give notice as
     provided herein will not relieve the Indemnifying Party of its obligations
     under this Section 2.5.

No  Indemnifying  Party,  in the  defense of any such claim or  litigation,
will, except with the consent of each Indemnified Party, consent to entry of any
judgment or enter into any  settlement  (which  judgment or settlement  would be
adverse to and binding upon such Indemnified  Party) of any claim for which such
Indemnified Party may seek indemnification hereunder;  provided that, as to each
Indemnified  Party  withholding such consent,  the maximum amount of the losses,
damages or  liabilities  in respect  of which  such  Indemnified  Party may seek
indemnification  hereunder  with  respect to such claim is limited to the amount
which the Indemnifying Party would have paid to or on behalf of such Indemnified
Party had such Indemnified Party consented to such judgment or settlement.

CLCORP01 Doc: 230115_4                  21

<PAGE>

          (d) If the indemnification provided for in this Section 2.5 is for
any  reason  unavailable  to an  Indemnified  Party in respect to any loss,
claim,  damage or  liability,  or any action in  respect  thereof,  referred  to
herein,  then  each  Indemnifying  Party  will,  in  lieu of  indemnifying  such
Indemnified Party,  contribute to the amount paid or payable by such Indemnified
Party as a result of such loss, claim, damage or liability, or action in respect
thereof,  in such  proportion  as shall be  appropriate  to reflect the relative
fault of the Indemnifying Party on the one hand and the Indemnified Party on the
other with respect to the  statements or omissions  which resulted in such loss,
claim,  damage or liability,  or action in respect thereof, as well as any other
relevant  equitable  considerations.  The relative  fault will be  determined by
reference to whether the untrue or alleged  untrue  statement of a material fact
or omission or alleged  omission to state a material fact relates to information
supplied by the Indemnifying  Party on the one hand or the Indemnified  Party on
the other,  the intent of the parties and their  relative  knowledge,  access to
information  and  opportunity  to correct or prevent such statement or omission,
but not by reference to any  Indemnified  Party's stock ownership in the Issuer.
In no event,  however,  will a holder of  Registrable

CLCORP01 Doc: 230115_4                  22

<PAGE>

Securities  be  required to  contribute  in excess of the amount of the net
proceeds  received by such  holder in  connection  with the sale of  Registrable
Securities in the offering which is the subject of such loss,  claim,  damage or
liability. The amount paid or payable by an Indemnified Party as a result of the
loss,  claim,  damage or liability,  or action in respect  thereof,  referred to
above in this paragraph includes,  for purposes of this paragraph,  any legal or
other expenses  reasonably incurred by such Indemnified Party in connection with
investigating  or  defending  any such  action  or claim.  No  Person  guilty of
fraudulent  misrepresentation  (within  the  meaning  of  Section  11(f)  of the
Securities Act)) is entitled to contribution  from any Person who was not guilty
of such fraudulent misrepresentation.

          2.6 Information by Holders.  If Registrable  Securities  owned by a
Qualified Holder are included in any registration, such holder will furnish to
the Issuer such information regarding itself and the distribution proposed by
such holder as the Issuer may reasonably request and as is required in
connection with any registration, qualification or compliance referred to in
this Article 2.

          2.7 Rule 144 Reporting. With a view to making available to each
Qualified Holder the benefits of certain rules

CLCORP01 Doc: 230115_4                  23

<PAGE>

and  regulations  of the  Commission  which  may  permit  the  sale  of the
Registrable  Securities to the public  without  registration,  the Issuer agrees
that so long as a holder owns any Registrable Securities,  the Issuer shall, (a)
make and keep available public  information,  as those terms are contemplated by
Rule 144 under the  Securities  Act;  (b) timely  file with the  Commission  all
reports and other  documents  required to be filed under the  Securities Act and
the  Securities  Exchange Act of 1934 (the "Exchange  Act");  and (c) furnish to
each holder  forthwith upon request a written  statement by the Issuer as to its
compliance  with  the  reporting  requirements  of the  Securities  Act  and the
Exchange  Act,  a copy of the most  recent  annual  or  quarterly  report of the
Issuer,  and such other  information  as such holder may  reasonably  request in
order to avail itself of any rule or regulation of the Commission  allowing such
holder to sell any Registrable Securities without registration.

          2.8 Future Registration Rights.  (a)  The Issuer will not hereafter
agree with the holders of any securities issued or to be issued by the Issuer
to register such securities under the Securities Act unless such agreement
specifically provides that (i) such holder of securities may not participate in
any Piggyback Registration except as provided in Section 2.1, (ii)

CLCORP01 Doc: 230115_4                  24

<PAGE>

the  holder  of  such  securities  may  not  participate  in any  Requested
Registration  except as provided in Section 2.2,  (iii) unless in the opinion of
the managing underwriter or underwriters,  if any, of any Piggyback Registration
or Requested  Registration  the public offering or sale of such other securities
would not interfere with the successful  public offering and sale of Registrable
Securities requested to be included in such Piggyback  Registration or Requested
Registration,  such other  securities  will not be  included  in a  registration
statement in which such shares of Registrable  Securities  are so included,  and
(iv) such  securities  may not be  publicly  offered  or sold for a period of at
least  ninety  (90) days after the date upon which such  registration  statement
becomes  effective.  This  Section 2.8 is not  violated by the future  grants of
registration   rights   provided  such  rights  are  subject  to  the  foregoing
restrictions  and are  exercisable on a pro rata basis with all other holders of
such  rights,  and the Issuer is not be  required  to obtain the  consent of any
party hereto with respect to such future grants.

          (b) From and after the date hereof, the Issuer shall not enter into
any agreement with any holder or prospective holder of any securities of the
Issuer providing for the granting to such holder of registration rights
(including demand

CLCORP01 Doc: 230115_4                  25

<PAGE>

registration rights which, by their terms, do not permit the inclusion of
shares of parties other than the holders of such demand registration rights)
that entitle such holder to priority over a Qualified Holder with respect to
registration of the securities of the Issuer.

          2.9  Permitted Interruption.  Notwithstanding any provision of this
Article  2,  the  Issuer  shall  not  be  required  to  prepare  or  file a
registration  statement,   amendment  or  post-effective  amendment  thereto  or
prospectus  supplement or to supplement or amend any  registration  statement or
otherwise facilitate the resale of Registrable Securities,  and the Issuer shall
be free to take or omit to take  any  other  action  that  would  result  in the
impracticality  of any such filing,  supplement  or  amendment,  if such filing,
supplement or amendment (and any required disclosure therein), in the good faith
and  reasonable  judgment of the Issuer,  would  jeopardize  the completion of a
material  investment in the Issuer,  or any  acquisition,  divestiture  or other
similar transaction that the Issuer is at such time in negotiations therefor, so
long as the Issuer shall,  as promptly as  practicable  after the  conclusion of
such negotiations,  make such filing, supplement or amendment and so long as the
Issuer  shall,   as  promptly  as  practicable   thereafter,   comply  with  the
requirements

CLCORP01 Doc: 230115_4                  26

<PAGE>

of this  Article 2, if  applicable  (any period  described in this
Section  2.9 during  which the  Company  is not  required  to make such  filing,
amendment or supplement being herein a "Permitted Interruption"). If a Qualified
Holder has  requested  registration  of New Shares in a Requested  Registration,
Piggyback  Registration  or Cutback  Registration  and a Permitted  Interruption
affects that  registration,  the Issuer  agrees to notify each of the Holders so
affected  by  a  Permitted  Interruption  upon  each  of  the  commencement  and
termination of each Permitted Interruption.  The Issuer shall not be required in
the notice of a Permitted  Interruption to disclose the cause for such Permitted
Interruption. The Permitted Interruption terminates upon the termination of such
negotiations or the public disclosure thereof.

                                   Article 3

                                 MISCELLANEOUS

          3.1  Notices.  Except as otherwise specifically provided in this
Agreement, all communications hereunder shall be sent in the manner and to the
addresses set forth in Section 11.1 of the Option Purchase Agreement and, as to
any Qualified Holder, to an address provided to Issuer by such Holder for
purposes of notices hereunder.

CLCORP01 Doc: 230115_4                  27

<PAGE>

          3.2  Non-Waiver of Remedies and Actions By Holders.  No course of
dealing between the Issuer and any Qualified Holder or any delay on the part of
such holder in exercising any rights available to such holder operates as a
waiver of any right of such holder, except to the extent expressly waived in
writing by such holder.

          3.3  Headings.  The headings in this Agreement are for purposes of
reference only and are not to be considered in construing this Agreement.

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

          3.5  Successors and Assigns.  This Agreement binds and inures to the
benefit of the successors of any Qualified Holders and the Issuer.  Except for
Option Acquisition's right to designate up to two other Qualified Holders as
expressly provided herein, no Qualified Holder may assign any of the rights
created by this Agreement.

          3.6  Consent of Holders; Waiver.  (a)  Whenever, by the terms hereof,
anything is required to be done to the satisfaction of the Qualified Holders,
or such Holders are to appoint a

CLCORP01 Doc: 230115_4                  28

<PAGE>

representative, if such satisfaction, or appointment is necessary in connection
with a specific registration being effected hereunder, it will be effective
when done by the Qualified Holders holding a majority of the Registrable
Securities held by Qualified Holders that are being included in such
registration.

          (b) Except as provided in Section 3.6(a), whenever, by the terms
hereof,  the  consent of the  Qualified  Holders is  required,  anything is
required to be done to the satisfaction of such holders,  or if such holders are
to appoint a  representative,  such consent,  satisfaction,  or  appointment  is
effective when done by Qualified  Holders  holding a majority of the Registrable
Securities held by Qualified Holders.

          (c) All rights and remedies hereunder for the benefit of the
Qualified Holders are intended to be for the benefit of each holder of

                                      Agreement

          NOW, THEREFORE, in consideration of the foregoing, the covenants of
the Option Purchase Agreement and this Amendment, the parties agree as follows:

          1. Expand Definition of Registrable Securities.  Recital D of the
Original Agreement is hereby amended to delete the parentheses and

     and Secondary Option Shares received upon exercise of the Supplier
     Option; and (C) Qualified New Option Shares; but does not include any
     other Issuer Common Shares or other securities of the Issuer which may
     now or hereafter be held or acquired by any holder of Registrable
     Securities.  Securities will cease to be Registrable Securities upon the
     first to occur of the following:  (i) such securities have been sold
     pursuant to a registration or pursuant to Rule 144 promulgated by the
     Securities and Exchange Commission (or any similar rule then in force);
     (ii) with respect to Issuer Common Shares issued upon exercise of the
     Incentive Stock Options, to the extent such securities have been
     previously registered if they may be resold by the holder thereof without
     registration or limitation; and (iii) such securities have been exchanged,
     substituted or replaced by securities which have been registered under the
     Securities Act.  For all purposes of this Agreement, a holder of
     Registrable Securities shall be deemed to hold any Registrable Securities
     issuable to such holder upon conversion or exercise of, or in exchange
     for, Convertible Securities of the types described in clause (A) or (B) of
     this Section (x), disregarding any legal, regulatory or

     contractual restrictions on such conversion, exercise or exchange.

          2. Add Definition of Qualified New Option Shares.  Section 1(xiii) of
the Original Agreement is hereby renumbered to be Section 1(ix), Section 1(x)

     New Option, except that (A) no such shares are Qualified New Option Shares
     until January 1, 1999, (B) any such shares shall cease being Qualified New
     Option Shares from and after the first day that Individual and/or Members
     of the McCaw Family (as defined in Section 4 of the First Amendment to
     Registration Rights Agreement dated as of June 16, 1997 among the Issuer,
     Investor and Option Acquisition) no longer control Option Acquisition, (C)
     no such shares are Qualified New Option Shares from and after the time
     that the number of Issuer Common Shares held by Option Acquisition is less
     than 1% of the outstanding Issuer Common Shares and the holding period
     under Rule 144 of the Securities Act applicable to Option Acquisition has
     been satisfied.

          3. Notices to Option Acquisition.  From and after January 1, 1999,
the Issuer will send to Option Acquisition (at the address specified for
notices under the Option Purchase Agreement) a copy of any notice that the
Issuer sends to the Investor under the Original Agreement (as amended by this
Amendment, and as the same may be further amended, the "Investor Registration
Rights Agreement").

          4. Change in Control of Option Acquisition. (a) If Option Acquisition
becomes aware that it is no longer controlled by Individual and/or Members of
the McCaw Family (as defined below), Option Acquisition will notify Issuer of
that fact and this Amendment will be void and without further force or effect.
Solely for purposes of the Introductory Statement (as it relates to control of
Option Acquisition) and Section 4 of this Amendment, and for purposes of
Section 1 (viii) (B) of the Original Agreement (as amended by this Amendment),
the terms "controls" and "controlled by" shall mean that Individual and/or
Members of the McCaw Family have the sole possession of at least 2/3 of the
voting and investment power over management and policies of Option Acquisition
including, without limitation, the sole authority to make all decisions with

securities of the Company owned or available for purchase by Option
Acquisition pursuant to the Option Purchase Agreement and the New Options. For
purposes of Section 4 of this Amendment and Section 1(viii) of the Original
Agreement (as amended by this Amendment), "Members of the McCaw Family" means

foundation established by any such persons that holds all or any part of
such persons' interests in Option Acquisition either during the lifetime or
upon the death of any such persons.

          (b) At any time that Option acquisition is exercising any rights as a
holder of Registrable Securities pursuant to the Investor Registration Rights
Agreement, the Issuer may require Option Acquisition and Individual (or a
Member of the McCaw Family if Individual is deceased on incapacitated at the
time) to certify that Individual and/or Members of the McCaw Family control
Option Acquisition. 

          5. Reaffirmation of Original Agreement.  Except as expressly stated
in this Amendment, the Original Agreement remains in full force and effect.

          IN WITNESS WHEREOF, the parties have caused this Amendment to be duly
executed on their behalf, as of the day and year first above written.

have entered into an Option Purchase

<PAGE>

                                                                           2

Agreement dated as of June 16, 1997 (the "Option Purchase Agreement") pursuant
to which, among other things, the Buyer agreed to purchase from USFC certain
options (the "Old Options") to acquire up to 25,000,000 shares of the Company's

Buyer and the Company agreed to exchange the Old Options for two options to
purchase shares of Common Stock, on the terms set forth in the Option Purchase
Agreement, this Option, and the Second New Option.

           An affiliate of Buyer, Digital Radio, L.L.C. ("Investor"), is a
stockholder of the Company and holds an Option Agreement (First Tranche) issued
by the Company to Investor on July 28, 1995 (the "Investor's First Option") to
purchase Common Stock of the Company.

                                 AGREEMENT

          NOW, THEREFORE, for the consideration set forth in the Option
Purchase Agreement and other good and valuable consideration, the sufficiency
and receipt of which is hereby acknowledged, the Company agrees with Buyer as
follows:

          1. GRANT OF OPTION.

          1.1  Grant.  The Company hereby grants to Buyer this Option,
exercisable  as  provided  herein  in whole or in part at any time and from
time to time  during the period from  (A) the  date that  Investor  has paid the
exercise price and exercised,  in full,  the  Investor's  First Option,  through
(B) 6:00 p.m., local time in New York, New York, on July 28, 1998 (the "Exercise
Period") to purchase an aggregate of up to Fifteen Million  (15,000,000)  shares
of Common  Stock (as such number may be  adjusted  pursuant to Section 2 hereof,
the "Option  Shares"),  at an exercise  price of $16.00 per share (as such price
may be adjusted pursuant to Section 2 hereof, the "Exercise  Price").  Buyer and
its permitted successors and assigns are hereinafter referred to as "Holder."

          1.2  Shares To Be Issued; Reservation of Shares.  The Company
covenants and agrees that all Option Shares will, upon issuance, be duly
authorized, validly issued and outstanding, fully paid and non-assessable, and
free from all taxes, liens and charges with respect to the issuance thereof,
except as otherwise provided in the Option Purchase Agreement.  The Company
further

                                                                           3

<PAGE>

covenants and agrees that it will from time to time take all actions required
to assure that the par value per share of the Common Stock is at all times
equal to or less than the effective Exercise Price.  The Company further
covenants and agrees that, during the Exercise Period, the Company will at all
times have authorized and reserved sufficient shares of Common Stock to provide
for the exercise of this Option in full.

          2. ADJUSTMENTS TO OPTION RIGHTS.

          2.1 Stock Combinations. If the Company combines all of the
outstanding Common Stock  proportionately  into a smaller number of shares,
the Exercise  Price per Option Share  hereunder in effect  immediately  prior to
such  combination  will be  proportionately  increased  and the number of Option
Shares   issuable  to  the  Holder   upon   exercise  of  this  Option  will  be
proportionately decreased, as of the effective date of such combination.

          2.2  Reorganizations.  If any of the following transactions (each, a
"Special  Transaction") becomes effective:  (i) a capital reorganization or
reclassification  of the capital stock of the Company,  (ii) a consolidation  or
merger of the Company with another  entity or (iii) a sale or  conveyance of all
or substantially all of the Company's  assets,  then, as a condition of any such
Special  Transaction,  lawful and adequate  provision  shall be made whereby the
Holder shall  thereafter  have the right to purchase  and  receive,  at any time
after the consummation of such transaction  until the expiration of the Exercise
Period,  upon the basis and upon the terms and conditions  specified herein, and
in lieu of the Option Shares immediately  theretofore  issuable upon exercise of
this Option for the aggregate Exercise Price in effect immediately prior to such
consummation,  such shares of stock,  other securities,  cash or other assets as
may be  issued  or  payable  in  and  pursuant  to the  terms  of  such  Special
Transaction with respect to or in exchange for a number of outstanding shares of
Common  Stock  equal to the  number of  Option  Shares  immediately  theretofore
issuable upon exercise in full of this Option had such Special  Transaction  not
taken place (pro rated in the case of any partial exercises). In connection with
any Special Transaction,  appropriate provision will be made with respect to the
rights and interests of the Holder to the end that the provisions of this Option
(including  without  limitation  provisions for adjustment of the Exercise

Option),  will  thereafter be applicable,  as nearly as may be, to any shares of
stock,  other securities,  cash or other assets thereafter  deliverable upon the
exercise of this  Option.  The Company  will not effect any Special  Transaction
unless  prior to or  simultaneously  with the closing the  successor  entity (if
other than the Company),  if any, resulting from such consolidation or merger or
the entity  acquiring such assets assumes by a written  instrument  executed and
mailed by certified mail or delivered to the Holder (which  instrument  shall be
in form and substance  reasonably  satisfactory to Holder) at the address of the
Holder  appearing on the books of the Company,  the obligation of the Company or
such  successor  corporation  to deliver to such  Holder  such  shares of stock,
securities,   cash  or  other  assets  as,  in  accordance  with  the  foregoing
provisions, such Holder has rights to purchase.

          2.3  Adjustment Upon Changes in Capitalization.  In the event of any
change in the  Common  Stock by reason of stock  dividends,  stock  splits,
recapitalizations,  reclassifications or the like, the type and number of Option
Shares  issuable upon exercise of this Option,  and the Exercise  Price,  as the
case may be, will be adjusted  appropriately,  immediately upon such change.  No
such  adjustment  will be made on account of any dividend  payable other than in
stock of the Company.

          2.4  Notice.  Whenever this Option, the Option Shares or the Exercise
Price is to be adjusted as  provided  herein or a dividend or  distribution
(in cash, stock or otherwise and including,  without limitation, any liquidating
distributions)  is to be declared by the Company,  or a Special  Transaction  is
deemed by the Company to be substantially certain to occur (other than a Special
Transaction  in which the  Company is the  surviving  entity and which would not
require the execution of a written  instrument  pursuant to Section 2.2  above),
the Company will forthwith cause to be sent to the Holder at the last address of
the Holder  shown on the books of the  Company,  by  first-class  mail,  postage
prepaid,  at least ten (10) days prior to the record date specified in (A) below
or at least twenty (20) days before the date  specified  in (B) below,  a notice
stating  in  reasonable  detail  the facts  requiring  such  adjustment  and the
calculation thereof, if applicable, and stating (if applicable):

                                                                           5

          (A) the record date of such dividend, distribution, subdivision or
combination,  or, if a record is not to be taken,  the date as of which the
holders of Common Stock of record to be entitled to such dividend, distribution,
subdivision or combination are to be determined (provided, that in the event the
Company institutes a policy of declaring cash dividends on a periodic basis, the
Company need only provide the relevant information called for in this clause (A)
with  respect to the first cash  dividend  payment to be made  pursuant  to such
policy and  thereafter  provide  only notice of any changes in the amount or the
frequency of any subsequent dividend payments), or

          (B) the date on which a Special Transaction is expected to become
effective, and the date as of which it is expected that holders of Common Stock
of record are entitled to exchange their shares of Common Stock for securities
or other property deliverable upon consummation of the Special Transaction.

          2.5  Fractional Interests.  This Option may be exercised only for a
whole number of shares of Common Stock,  other than any fraction of a share
of Common  Stock which would  result upon this Option  being  exercised in full;
provided,  however that the Company is not required to issue fractions of shares
of Common  Stock on the  exercise in full of this  Option.  If any fraction of a
share of Common Stock would,  except for the  provisions of this Section 2.5, be
issuable  upon the exercise in full of this Option,  the Company may (in lieu of
issuing such  fractional  share) either (A) purchase such fraction for an amount
in cash equal to the current value of such fraction,  computed (i) if the Common
Stock is listed  or  admitted  to  unlisted  trading  privileges  on the  NASDAQ
National  Market  System or any  securities  exchange,  on the basis of the last
reported  sale price of the Common Stock on such  exchange on the last  business
day  prior to the date of  exercise  upon  which  such a sale  shall  have  been
effected  (or,  if the Common  Stock  shall be listed or  admitted  to  unlisted
trading privileges on more than one such exchange, on the basis of such price on
the  exchange  designated  from  time to time for such  purpose  by the Board of
Directors  of the  Company)  or (ii) if the  Common  Stock is not so  listed  or
admitted to unlisted trading privileges,  on the basis of the last bid price, or
if there is no reported last bid, the average of the bid prices,  for the Common
Stock on the last business day prior to the date of exercise, as reported by the
National  Association of

Securities  Dealers  Automated  Quotation System or any successor thereto, or,
if such computations cannot be made as aforesaid, as the Board of  Directors of
the Company may in good faith  determine  or (B) issue a number of whole shares
determined by rounding up to the nearest whole share.

          3.  EXERCISE.

          3.1  Exercise of Option. Subject to compliance with federal and state
securities laws and to Section 1.1, the Holder may exercise this Option, in
whole or in part,  at any time during the  Exercise  Period by (i)  surrendering
this Option,  with the form of exercise  notice  attached  hereto as Exhibit "A"
duly  executed  by Holder,  and (ii) either  electing  cashless  exercise  under
Section 3.2 or making payment to the Company of the aggregate Exercise Price for
the  applicable  Option Shares by wire transfer to an account  designated by the
Company.  Upon any partial exercise of this Option, the Company, at its expense,
will  forthwith  issue to the  Holder  for  this  option  a  replacement  Option
identical  in all  respects  to this  Option,  except  that the number of Option
Shares shall be reduced accordingly.

          3.2  Cashless Exercise.  Instead of making payment under Section
3.1(ii) this Option may be exercised on a net basis, such that,  without an
exchange of any funds,  the Holder  receives  upon exercise the number of shares
designated  on the  exercise  notice less that number of shares of Common  Stock
having an aggregate  value  computed on the basis of the Average Market Price at
the time of  exercise  equal to  Exercise  Price for the  shares so  designated.
"Average  Market Price" means the arithmetic  average of the closing sales price
for a share of Common Stock on the NASDAQ-NM for the 20 trading days immediately
preceding the date on which the price is to be determined.

          3.3  Issuance of Option Shares.  The Option Shares purchased will
be issued to the Holder  exercising this Option as of the close of business
on the date on which all  actions and  payments  required to be taken or made by
Holder,  pursuant to Section 3.1, have been taken or made.  Certificates for the
Option  Shares so purchased  will be delivered to the Holder within a reasonable
time, not exceeding ten (10) days after this Option is surrendered.

          4. NO DILUTION OR IMPAIRMENT.  The Company will not, by amendment
of its Certificate of  Incorporation  or Bylaws or through  reorganization,
reclassification,  consolidation,  merger,  dissolution,  sale of  assets or any
other voluntary action,  avoid or seek to avoid the observance or performance of
any of the terms of this  Option,  but will at all times in good faith assist in
the  carrying  out of all such terms and in the taking of all such action as may
be necessary or appropriate in order to protect the rights of the Holder against
dilution or other impairment.  Without limiting the generality of the foregoing,
the  Company  will not  increase  the par value of any  shares  of Common  Stock
receivable upon the exercise of this Option above the Exercise Price, and at all
times will take all such action as may be necessary or appropriate in order that
the Company may validly and legally issue fully paid and  non-assessable  shares
of Common Stock upon the exercise of this Option. In the event of actions, other
than those specified herein,  affecting  adversely the rights of the Holder, the
Board of  Directors  of the  Company  will  make  such  adjustments  as shall be
equitable  in the  circumstances  to  preserve  for Holder the  benefits of this
Option.

          5. RIGHTS OF HOLDER.  Holder is not, solely by virtue of this Option
and prior to the issuance of the Option Shares upon due exercise thereof,
entitled to any rights of a stockholder in the Company.

          6.  TRANSFERABILITY.  Holder may sell, assign, transfer or otherwise
     dispose  of this  Option  only in  accordance  with the terms of the Option
Purchase Agreement. Subject to compliance with federal and state securities laws
and with the Option  Purchase  Agreement,  if  applicable,  the Holder may sell,
assign,  transfer or otherwise  dispose of any Option  Shares  acquired upon any
exercise hereof at any time and from time to time.

          7.  LEGEND ON OPTION SHARES.  Certificates evidencing the Option
Shares will bear the following legend: "THE SECURITIES  REPRESENTED BY THIS
CERTIFICATE OR INSTRUMENT HAVE NOT BEEN  REGISTERED  UNDER THE SECURITIES ACT OF
1933, AS AMENDED (THE "ACT"),  OR UNDER ANY APPLICABLE STATE LAWS AND MAY NOT BE

          8.4  No Implied Waiver; Rights Are Cumulative.  The failure to
exercise or the delay in exercising by either party of any right, remedy, power
or privilege under this Option, will not operate as a waiver thereof.  The

          1.1  Grant.  The Company hereby grants to Buyer this Option,
exercisable  as  provided  herein  in whole or in part at any time and from
time to time  during the period from  (A) the  date that  Investor  has paid the
exercise  price and  exercised  in full the  Investor's  First  Option,  through
(B) 6:00 p.m., local time in New York, New York, on July 28, 1998 (the "Exercise
Period") to purchase an aggregate of up to  Ten Million  (10,000,000)  shares of
Common Stock (as such number may be adjusted  pursuant to Section 2 hereof,  the
"Option Shares"), at an exercise price of $18.00 per share (as such price may be
adjusted  pursuant to Section 2 hereof,  the  "Exercise  Price").  Buyer and its
permitted successors and assigns are hereinafter referred to as "Holder."

          1.2  Shares To Be Issued; Reservation of Shares.  The Company
covenants and agrees that all Option Shares will, upon issuance, be duly
authorized, validly issued and outstanding, fully paid and non-assessable, and
free from all taxes, liens and charges with respect to the issuance thereof,
except as otherwise

                                                                           3

provided in the Option Purchase  Agreement.  The Company further  covenants
and agrees  that it will from time to time take all  actions  required to assure
that the par  value per share of the  Common  Stock is at all times  equal to or
less than the effective Exercise Price. The Company further covenants and agrees
that, during the Exercise Period,  the Company will at all times have authorized
and  reserved  sufficient  shares of Common Stock to provide for the exercise of
this Option in full.

          2. ADJUSTMENTS TO OPTION RIGHTS.

          2.1  Stock Combinations.  If the Company combines all of the
outstanding Common Stock proportionately into a smaller number of shares, the
Exercise Price per Option Share hereunder in effect immediately prior to such
combination will be proportionately increased and the number of Option Shares
issuable to the Holder upon exercise of this Option will be proportionately
decreased, as of the effective date of such combination.

          2.2 Reorganizations.  If any of the following transactions (each, a
     "Special  Transaction") becomes effective:  (i) a capital reorganization or
reclassification  of the capital stock of the Company,  (ii) a consolidation  or
merger of the Company with another  entity or (iii) a sale or  conveyance of all
or substantially all of the Company's  assets,  then, as a condition of any such
Special  Transaction,  lawful and adequate  provision  shall be made whereby the
Holder shall  thereafter  have the right to purchase  and  receive,  at any time
after the consummation of such transaction  until the expiration of the Exercise
Period,  upon the basis and upon the terms and conditions  specified herein, and
in lieu of the Option Shares immediately  theretofore  issuable upon exercise of
this Option for the aggregate Exercise Price in effect immediately prior to such
consummation,  such shares of stock,  other securities,  cash or other assets as
may be  issued  or  payable  in  and  pursuant  to the  terms  of  such  Special
Transaction with respect to or in exchange for a number of outstanding shares of
Common  Stock  equal to the  number of  Option  Shares  immediately  theretofore
issuable upon exercise in full of this Option had such Special Transaction not

<PAGE>

                                                                           4

taken place (pro rated in the case of any partial exercises). In connection
with any Special Transaction, appropriate provision will be made with respect to
the rights and  interests of the Holder to the end that the  provisions  of this
Option (including without  limitation  provisions for adjustment of the Exercise
Price and the number of Option Shares issuable upon the exercise of the Option),
will  thereafter  be  applicable,  as nearly as may be, to any  shares of stock,
other securities,  cash or other assets thereafter deliverable upon the exercise
of this Option. The Company will not effect any Special Transaction unless prior
to or  simultaneously  with the closing the successor  entity (if other than the
Company),  if any,  resulting  from such  consolidation  or merger or the entity
acquiring  such assets  assumes by a written  instrument  executed and mailed by
certified mail or delivered to the Holder (which instrument shall be in form and
substance  reasonably  satisfactory  to  Holder)  at the  address  of the Holder
appearing on the books of the  Company,  the  obligation  of the Company or such
successor   corporation  to  deliver  to  such  Holder  such  shares  of  stock,
securities,   cash  or  other  assets  as,  in  accordance  with  the  foregoing
provisions, such Holder has rights to purchase.

          2.3  Adjustment Upon Changes in Capitalization.  In the event of any
change in the  Common  Stock by reason of stock  dividends,  stock  splits,
recapitalizations,  reclassifications or the like, the type and number of Option
Shares  issuable upon exercise of this Option,  and the Exercise  Price,  as the
case may be, will be adjusted  appropriately,  immediately upon such change.  No
such  adjustment  will be made on account of any dividend  payable other than in
stock of the Company.

          2.4  Notice. Whenever this Option, the Option Shares or the Exercise
Price is to be adjusted as  provided  herein or a dividend or  distribution
(in cash, stock or otherwise and including,  without limitation, any liquidating
distributions)  is to be declared by the Company,  or a Special  Transaction  is
deemed by the Company to be substantially certain to occur (other than a Special
Transaction  in which the  Company is the  surviving  entity and which would not
require the execution of a written  instrument  pursuant to Section 2.2  above),
the Company will forthwith cause to be sent to the Holder at the last address of
the Holder shown on the books of the Company, by first-class mail, postage

                                                                           5

prepaid,  at least ten (10) days prior to the record date  specified in (A)
below or at least  twenty (20) days before the date  specified  in (B) below,  a
notice stating in reasonable  detail the facts requiring such adjustment and the
calculation thereof, if applicable, and stating (if applicable):

          (A) the record date of such dividend, distribution, subdivision or
combination,  or, if a record is not to be taken,  the date as of which the
holders of Common Stock of record to be entitled to such dividend, distribution,
subdivision or combination are to be determined (provided, that in the event the
Company institutes a policy of declaring cash dividends on a periodic basis, the
Company need only provide the relevant information called for in this clause (A)
with  respect to the first cash  dividend  payment to be made  pursuant  to such
policy and  thereafter  provide  only notice of any changes in the amount or the
frequency of any subsequent dividend payments), or

          (B)  the date on which a Special Transaction is expected to become
     effective,  and the date as of which it is expected  that holders of Common
Stock of record  are  entitled  to  exchange  their  shares of Common  Stock for
securities  or other  property  deliverable  upon  consummation  of the  Special
Transaction.

          2.5  Fractional Interests.  This Option may be exercised only for a
whole number of shares of Common Stock,  other than any fraction of a share
of Common  Stock which would  result upon this Option  being  exercised in full;
provided,  however that the Company is not required to issue fractions of shares
of Common  Stock on the  exercise in full of this  Option.  If any fraction of a
share of Common Stock would,  except for the  provisions of this Section 2.5, be
issuable  upon the exercise in full of this Option,  the Company may (in lieu of
issuing such  fractional  share) either (A) purchase such fraction for an amount
in cash equal to the current value of such fraction,  computed (i) if the Common
Stock is listed  or  admitted  to  unlisted  trading  privileges  on the  NASDAQ
National  Market  System or any  securities  exchange,  on the basis of the last
reported  sale price of the Common Stock on such  exchange on the last  business
day  prior to the date of  exercise  upon  which  such a sale  shall  have  been
effected (or, if the Common Stock shall be listed or admitted to

                                                                           6

     unlisted trading privileges on more than one such exchange, on the basis of
such price on the exchange  designated from time to time for such purpose by the
Board of  Directors of the Company) or (ii) if the Common Stock is not so listed
or admitted to unlisted trading privileges,  on the basis of the last bid price,
or if there is no reported  last bid,  the  average of the bid  prices,  for the
Common Stock on the last business day prior to the date of exercise, as reported
by the National  Association of Securities Dealers Automated Quotation System or
any successor thereto, or, if such computations cannot be made as aforesaid,  as
the Board of Directors of the Company may in good faith determine or (B) issue a
number of whole shares determined by rounding up to the nearest whole share.

          3.  EXERCISE.

          3.1  Exercise of Option. Subject to compliance with federal and state
securities laws and to Section 1.1, the Holder may exercise this Option, in
whole or in part,  at any time during the  Exercise  Period by (i)  surrendering
this Option,  with the form of exercise  notice  attached  hereto as Exhibit "A"
duly  executed  by Holder,  and (ii) either  electing  cashless  exercise  under
Section 3.2 or making payment to the Company of the aggregate Exercise Price for
the  applicable  Option Shares by wire transfer to an account  designated by the
Company.  Upon any partial exercise of this Option, the Company, at its expense,
will  forthwith  issue to the  Holder  for  this  option  a  replacement  Option
identical  in all  respects  to this  Option,  except  that the number of Option
Shares shall be reduced accordingly.

          3.2  Cashless Exercise.  Instead of making payment under Section
3.1(ii) this Option may be exercised on a net basis, such that,  without an
exchange of any funds,  the Holder  receives  upon exercise the number of shares
designated  on the  exercise  notice less that number of shares of Common  Stock
having an aggregate  value  computed on the basis of the Average Market Price at
the time of exercise  equal to the Exercise  Price for the shares so designated.
"Average  Market Price" means the arithmetic  average of the closing sales price
for a share of Common Stock on the NASDAQ-NM for the 20 trading days immediately
preceding the date on which the price is to be determined.

          3.3  Issuance of Option Shares.  The Option Shares purchased will
be issued to the Holder  exercising this Option as of the close of business
on the date on which all  actions and  payments  required to be taken or made by
Holder,  pursuant to Section 3.1, have been taken or made.  Certificates for the
Option  Shares so purchased  will be delivered to the Holder within a reasonable
time, not exceeding ten (10) days after this Option is surrendered.

          4.  NO DILUTION OR IMPAIRMENT. The Company will not, by
amendment  of  its  Certificate  of  Incorporation  or  Bylaws  or  through
reorganization,  reclassification,  consolidation,  merger, dissolution, sale of
assets or any other voluntary  action,  avoid or seek to avoid the observance or
performance  of any of the terms of this  Option,  but will at all times in good
faith assist in the carrying out of all such terms and in the taking of all such
action as may be necessary or  appropriate in order to protect the rights of the
Holder against dilution or other impairment.  Without limiting the generality of
the  foregoing,  the Company  will not  increase  the par value of any shares of
Common  Stock  receivable  upon the  exercise of this Option  above the Exercise
Price,  and at all  times  will  take all such  action  as may be  necessary  or
appropriate  in order that the Company may validly and legally  issue fully paid
and  non-assessable  shares of Common Stock upon the exercise of this Option. In
the event of actions, other than those specified herein, affecting adversely the
rights of the  Holder,  the Board of  Directors  of the  Company  will make such
adjustments  as shall be equitable in the  circumstances  to preserve for Holder
the benefits of this Option.

          5. RIGHTS OF HOLDER.  Holder is not, solely by virtue of this Option
and prior to the issuance of the Option Shares upon due exercise thereof,
entitled to any rights of a stockholder in the Company.

          6. TRANSFERABILITY. Holder may sell, assign, transfer or otherwise
dispose  of this  Option  only in  accordance  with the terms of the Option
Purchase Agreement. Subject to compliance with federal and state securities laws
and with the Option  Purchase  Agreement,  if  applicable,  the Holder may sell,
assign,  transfer or otherwise  dispose of any Option  Shares  acquired upon any
exercise hereof at any time and from time to time.

          7. LEGEND ON OPTION SHARES.  Certificates evidencing the Option
Shares will bear the following legend: "THE SECURITIES  REPRESENTED BY THIS
CERTIFICATE OR INSTRUMENT HAVE NOT BEEN  REGISTERED  UNDER THE SECURITIES ACT OF
1933, AS AMENDED (THE "ACT"),  OR UNDER ANY APPLICABLE STATE LAWS AND MAY NOT BE
TRANSFERRED,  SOLD OR  OTHERWISE  DISPOSED  OF IN THE  ABSENCE  OF AN  EFFECTIVE
REGISTRATION  UNDER THE ACT OR SUCH LAWS OR AN  OPINION  OF  COUNSEL  REASONABLY
SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE ACT
OR SUCH  LAWS  AND THE  RULES  AND  REGULATIONS  PROMULGATED  THEREUNDER."  Such
certificates  will  also be  legended  as  appropriate  to  reflect  any and all
restrictions  on transfer of such Option Shares that are contained in the Option
Purchase Agreement.

          8. MISCELLANEOUS.

          8.1 Amendments.  The parties may, from time to time, enter into
     written amendments,  supplements or modifications hereto for the purpose of
adding any  provisions  to this  Option or  changing in any manner the rights of

authorized  representative  of  each  party  and  effected  in  compliance  with

sent by giving notice of the change of address under this Section 8.2.

          8.3  Waiver By Consent.  The Holder may execute and deliver to the
Company a written instrument waiving, on such terms and conditions as the
Holder may specify in such instrument, any of the requirements of this Option
otherwise imposed on the Company.

          8.4  No Implied Waiver; Rights Are Cumulative.  The failure to
exercise or the delay in exercising  by either party of any right,  remedy,
power or privilege under this Option, will not operate as a waiver thereof.  The
single or partial exercise of any right,  remedy,  power or privilege under this
Option will not preclude any other or further  exercise  thereof or the exercise
of any other right, remedy, power or privilege. The rights, remedies, powers and
privileges  herein  provided  are  cumulative  and not  exclusive of any rights,
remedies, powers and privileges provided by law.

          8.5 Governing Law.  This Option and rights and obligations of the

concerning  the subject  matter  hereof and whether or not executed by Buyer and

                       REGISTRATION RIGHTS AGREEMENT
                            (Option Acquisition)

          THIS REGISTRATION RIGHTS AGREEMENT (this "Agreement") is entered into
June 18, 1997 by and among Nextel Communications, Inc., a Delaware
corporation (the "Issuer"), and Option Acquisition, L.L.C., a Washington
limited liability company ("Option Acquisition").  Capitalized terms that are
used but not otherwise defined herein are defined in Section 1.1.

                                     RECITALS

          A. Pursuant to an Option Purchase Agreement dated June 16, 1997,

registration,  and (B) second,  the Registrable  Securities  held by each
Qualified Holder and the Issuer Common Shares held by the Electing Holders,

               (1) if such Registrable Securities and/or Issuer Common Shares
               are sought to be included in such registration pursuant to
               contractual registration rights in existence on July 28, 1995,

               Shares, and

               (2) in all other cases, on a pro rata basis, based upon the

               Electing Holders originally sought to include in such
               registration.

          2.2 Requested Registration.

CLCORP01 Doc: 230115_4                  7

<PAGE>

qualifications  and  compliances   (including,   without  limitation,   the
execution  of an  undertaking  to  file  post-effective  amendments)  as  may be
requested  by the  Qualified  Holder who made the  original  request  and by the
Qualified  Holders who make written  request to the Issuer  within 20 days after
the giving of the aforesaid notice by the Issuer  ("Requesting  Holders") and as
would  permit  or  facilitate  the  sale  and  distribution  of the  Registrable
Securities as are specified in any such request; provided that the Issuer is not
obligated to take any action to effect a Requested  Registration  or any related
qualification or compliance pursuant to this Section 2.2:

               (i) if, within 60 days after receipt of the initial request
               pursuant to this Section 2.2, the Issuer elects to include in
               such registration Issuer Common Shares for its own account,
               whereupon the Issuer shall notify each Requesting Holder that it
               has elected to effect a Piggyback Registration and shall
               thereafter diligently proceed to do so, including therein the
               Registrable Securities as to which notice was given by the
               Requesting Holders pursuant to this Section 2.2 but subject to
               the limitations set forth in Section 2.1;

CLCORP01 Doc: 230115_4                  8

<PAGE>

               (ii) if the Requesting Holders do not request to include in such
               registration, in the aggregate, at least 3 million Registrable
               Securities; or

               (iii) if the Issuer has effected two Requested Registrations on
               behalf of Qualified Holder(s), which Requested Registrations
               have been declared or ordered effective and which effectiveness
               has not been suspended or stopped by any governmental or
               judicial authority.

          If the Requested Registration is a Cutback  Registration, the Issuer
shall register in such  registration (1) first, the Registrable  Securities
which any Requesting Holder seeks to include in such registration, on a pro rata
basis based upon the number of such Issuer Common Shares each Requesting  Holder
seeks to include in such  registration and (2) second,  the Issuer Common Shares
held by each Electing Holder,  (i) if such Issuer Common Shares are sought to be
included in such registration pursuant to contractual  obligations of the Issuer
in existence on July 28,  1995, in accordance  with the  respective  contractual
rights of the holder of such Issuer Common Shares,  and (ii) in all other cases,
on a pro rata basis based upon the number of shares each  Electing  Holder seeks
to include in such registration.

          (b) Underwriting.  If the Requesting Holders intend to distribute the
Registrable Securities covered by such request by means of an underwriting,
such Requesting Holders shall so advise the Issuer as a part of the request made
pursuant to this Section 2.2 and, in such event,  the  Requesting  Holders shall
select an  underwriter  of their  choice,  which  choice shall be subject to the
approval of the Board of Directors of the Issuer,  and which  approval shall not
be unreasonably withheld. The Issuer and such Requesting Holders shall negotiate
in good faith and enter into an  underwriting  agreement in customary  form with
the underwriter or underwriters selected for such underwriting.  If a Requesting
Holder disapproves of the terms of the underwriting,  such Requesting Holder may
elect to withdraw  therefrom  by written  notice to the Issuer and the  managing
underwriter,  and each of the remaining  Requesting Holders shall be entitled to
increase the number of shares being  registered,  to the extent permitted by the
managing  underwriter,   in  the  proportion  which  the  number  of  shares  of
Registrable  Securities being registered by such Requesting  Holder bears to the
total  number  of  shares  being  registered  by all such  remaining  Requesting
Holders.

Section 2.3, the Issuer will:

          (i) subject to Section 2.4(b) below, keep each registration effective

CLCORP01 Doc: 230115_4                 11

<PAGE>

     days that the Qualified Holders are unable to use a prospectus pursuant to
     Section 2.4(b) below) or until each such holder shall have completed the
     distribution described in the registration statement relating thereto,
     whichever first occurs (the "Registration Period"); and

          (ii) furnish such number of prospectuses (including preliminary
     prospectuses) and other documents filed with the Securities and Exchange
     Commission (the "Commission") as part of the registration statement as
     such holders from time to time may request.

          (b) If, within the Registration Period, there occurs any development
or any event which makes any statement in the registration statement or any
post-effective  amendment  thereto,  or any  document  incorporated  therein  by
reference,  untrue in any material  respect or which  requires the making of any
changes in the registration  statement or  post-effective  amendment  thereto or
prospectus or amendment or supplement thereto, so that they will not contain any
untrue  statement of a material fact or omit to state any material fact required
to be stated therein or necessary to make the statements therein (in the case of
any prospectus,  in the light of the  circumstances  under which they

CLCORP01 Doc: 230115_4                  12

<PAGE>

were  made) not  misleading,  the  Issuer  shall  immediately  notify  each
Qualified Holder included in such registration of the occurrence thereof and, as
soon as  reasonably  practicable,  prepare  and furnish to each such  holder,  a
reasonable number of copies of a prospectus  supplemented or amended so that, as
thereafter  delivered to purchasers of Registrable  Securities,  such prospectus
shall not  contain an untrue  statement  of a  material  fact or omit to state a
material fact required to be stated  therein or necessary to make the statements
therein,  in the light of the  circumstances  under  which they were  made,  not
misleading.  Each Qualified  Holder agrees that, upon receipt of any notice from
the  Issuer  pursuant  to this  Section  2.4(b),  such  holder  shall  forthwith
discontinue  disposition of Registrable  Securities until it shall have received
copies of such amended or  supplemented  prospectus,  and, if so directed by the
Issuer,  shall  deliver to the  Issuer all  copies,  other than  permanent  file
copies, then in its possession of the prospectus covering Registrable Securities
at the time of receipt of such notice.

          (c) Each Qualified Holder participating in any Cutback Registration
shall, as among all holders of Registrable Securities, be entitled to exercise
its rights hereunder pro rata

CLCORP01 Doc: 230115_4                  13

<PAGE>

according to the number of shares of Registrable Securities held by such
Qualified Holder and any Electing Holders.

          (d) If requested by the underwriters for any underwritten offering
of Registrable  Securities pursuant to a registration  requested under this
Agreement,  the  Issuer  will  enter into an  underwriting  agreement  with such
underwriters for such offering,  such agreement to contain such  representations
and  warranties  by the  Issuer  and such  other  terms  and  provisions  as are
customarily  contained  in  underwriting  agreements  with  respect to secondary
distributions,  including,  without limitation,  indemnities and contribution to
the effect and to the extent  provided  in Section  2.5 hereof and an opinion of
counsel  for the Issuer  dated the date of the  closing  under the  underwriting
agreement, and providing that the Issuer shall use its best efforts to furnish a
"cold comfort"  letter signed by the  independent  public  accountants  who have
audited  the  Issuer's  financial   statements  included  in  such  registration
statement,  in each such  case  covering  substantially  the same  matters  with
respect to such registration  statement (and the prospectus included therein) as
are  customarily  covered in opinions of  Issuer's  counsel and in  accountants'
letters delivered to underwriters in underwritten public offerings of securities
and

CLCORP01 Doc: 230115_4                  14

<PAGE>

such other matters as the underwriters  reasonably  request and, in the case
of such  accountants'  letter,  with respect to events subsequent to the date of
such financial statements. The holders of Registrable Securities on whose behalf
the Registrable  Securities are to be distributed by such underwriters  shall be
parties to any such underwriting agreement.

          (e) In connection with the preparation and filing of each
registration   statement  registering   Registrable  Securities  under  the
Securities Act, the Issuer will give the underwriters, if any, and their counsel
and  accountants,  such reasonable and customary access to its books and records
and such  opportunities  to discuss the business of the Issuer with its officers
and the independent public accountants who have certified the Issuer's financial
statements as shall be necessary,  in the opinion of such  underwriters or their
respective counsel, to conduct a reasonable  investigation within the meaning of
the Securities Act.

          2.5 Indemnification. (a) With respect to any registration which has
been effected pursuant to this Article 2, the Issuer shall indemnify each
Qualified Holder whose securities are included therein, each such holder's
directors and officers, each underwriter (as defined in the Securities Act) of
the securities

of such holder's securities, and each Person who controls (within the meaning of
the Securities Act) any such holder,  underwriter,  or participating Person from
and against all claims,  losses,  damages and liabilities (or actions in respect
thereof) arising out of or based on:

               (i) any untrue statement (or alleged untrue statement) of a
               material fact contained in any prospectus, offering circular or
               other document (including any related registration statement)
               incident to any such registration effected pursuant to this
               Article 2,

               (ii) any omission (or alleged omission) to state therein a
               material fact required to be stated therein or necessary to make
               the statements therein not misleading, or

               (iii) any violation by the Issuer of the Securities Act or any
               rule or regulation promulgated thereunder applicable to the
               Issuer, or any blue sky or state securities laws or any rule or
               regulation promulgated thereunder applicable to the Issuer,

in each case relating to action or inaction required of the Issuer in
connection with any such registration, and will

CLCORP01 Doc: 230115_4                  16

<PAGE>

     reimburse  each such Person  entitled to indemnity  hereunder for any legal
and other  expenses  reasonably  incurred in connection  with  investigating  or
defending any such claim, loss, damage,  liability or action; provided that, the
foregoing indemnity and reimbursement obligation is not applicable to the extent
that any such claim,  loss, damage or liability arises out of or is based on any
untrue statement (or alleged untrue statement) or omission (or alleged omission)
made in reliance upon and in conformity  with written  information  furnished to
the  Issuer  by or on  behalf  of such a holder  or by or on  behalf  of such an
underwriter specifically for use in such prospectus,  offering circular or other
document;  and further  provided that,  with respect to any untrue  statement or
omission  or  alleged  untrue  statement  or  omission  made in any  preliminary
prospectus,  the indemnity  agreement  contained in this Section 2.5(a) will not
inure to the  benefit of any  underwriter  to the extent  that any such  losses,
claims,  damages or  liabilities of such  underwriter  result from the fact that
there was not sent or given to any person who purchased  Registrable  Securities
in connection with such registration, at or prior to the written confirmation of
the sale of  Registrable  Securities  to such person,  a copy of the  prospectus
relating to such  registration,  as then amended or

CLCORP01 Doc: 230115_4                  17

<PAGE>

supplemented  (exclusive of material  incorporated  by reference),  if the
Issuer had  previously  furnished copies thereof to such underwriter.

          (b) Each holder of Registrable Securities which are included in such
registration, qualification or compliance shall indemnify the Issuer, its
directors and officers, each underwriter (as defined in the Securities Act) of
the securities of such holder, each other person who participates in the
offering of such holder's securities and each Person who controls (within the
meaning of the Securities Act) the Issuer or any such underwriter or
participating Person from and against all claims, losses, damages and
liabilities (or actions in respect thereof) arising out of or based on:

               (i) any untrue statement (or alleged untrue statement) of a
               material fact contained in any prospectus, offering circular or
               other document (including any related registration statement)
               incident to any such registration effected pursuant to this
               Article 2,

               (ii) any omission (or alleged omission) to state therein a
               material fact required to be stated therein or necessary to make
               the statements therein not misleading, or

CLCORP01 Doc: 230115_4                  18

<PAGE>

               (iii)any violation by such holder of the Securities Act or any
               rule or regulation promulgated thereunder applicable to such
               holder, or of any blue sky or other state securities law or any
               rule or regulation promulgated thereunder applicable to such
               holder,

in each case,  relating  to action or  inaction  required of such holder in
connection  with  any  registration,   qualification  or  compliance,  and  will
reimburse  each such Person  entitled to indemnity  hereunder  for any legal and
other expenses reasonably incurred in connection with investigating or defending
any such claim,  loss,  damage,  expense,  liability or action, but in each case
only to the extent that such untrue  statement (or alleged untrue  statement) or
omission (or alleged omission) is made in such prospectus,  offering circular or
other  document in reliance  upon and in  conformity  with  written  information
furnished  to the  Issuer by or on behalf of such  holder  specifically  for use
therein;  and further  provided  that,  with respect to any untrue  statement or
omission  or  alleged  untrue  statement  or  omission  made in any  preliminary
prospectus,  the indemnity  agreement  contained in this Section 2.5(b) will not
inure to the  benefit of any  underwriter  to the extent  that any such  losses,
claims,  damages or  liabilities of such  underwriter  result from the fact

CLCORP01 Doc: 230115_4                  19

<PAGE>

that there was not sent or given to any person  who  purchased  Registrable
Securities  in  connection  with such  registration,  at or prior to the written
confirmation of the sale of Registrable Securities to such person, a copy of the
prospectus  relating  to such  registration,  as then  amended  or  supplemented
(exclusive of material incorporated by reference),  if the Issuer had previously
furnished copies thereof to such underwriter.

          (c) Each party entitled to indemnification under this Section 2.5 (an
"Indemnified  Party")  shall give  notice to the party  required to provide
indemnification (the "Indemnifying  Party") promptly after the Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the  Indemnifying  Party to assume  the  defense of any such claim or any
litigation resulting  therefrom;  provided that

               (i) counsel for the Indemnifying Party who shall conduct the
     defense of any such claim or any litigation shall be approved by the
     Indemnified Party,

               (ii) the Indemnified Party may participate in such defense at
     the Indemnified Party's expense (provided that the Indemnified Party or
     Indemnified Parties have the right to employ one counsel to represent it
     or them if, in the reasonable judgment of the Indemnified Party or

CLCORP01 Doc: 230115_4                  20

<PAGE>

     or Indemnified Parties, it is advisable for it or them to be represented
     by separate counsel by reason of having legal defenses which are different
     from or in addition to those available to the Indemnifying Party, and in
     that event the fees and expenses of such one counsel will be paid by
     the Indemnifying Party), and

               (iii) failure of any Indemnified Party to give notice as
     provided herein will not relieve the Indemnifying Party of its obligations
     under this Section 2.5.

No  Indemnifying  Party,  in the  defense of any such claim or  litigation,
will, except with the consent of each Indemnified Party, consent to entry of any
judgment or enter into any  settlement  (which  judgment or settlement  would be
adverse to and binding upon such Indemnified  Party) of any claim for which such
Indemnified Party may seek indemnification hereunder;  provided that, as to each
Indemnified  Party  withholding such consent,  the maximum amount of the losses,
damages or  liabilities  in respect  of which  such  Indemnified  Party may seek
indemnification  hereunder  with  respect to such claim is limited to the amount
which the Indemnifying Party would have paid to or on behalf of such Indemnified
Party had such Indemnified Party consented to such judgment or settlement.

          (d) If the indemnification provided for in this Section 2.5 is for
any  reason  unavailable  to an  Indemnified  Party in respect to any loss,
claim,  damage or  liability,  or any action in  respect  thereof,  referred  to
herein,  then  each  Indemnifying  Party  will,  in  lieu of  indemnifying  such
Indemnified Party,  contribute to the amount paid or payable by such Indemnified
Party as a result of such loss, claim, damage or liability, or action in respect
thereof,  in such  proportion  as shall be  appropriate  to reflect the relative
fault of the Indemnifying Party on the one hand and the Indemnified Party on the
other with respect to the  statements or omissions  which resulted in such loss,
claim,  damage or liability,  or action in respect thereof, as well as any other
relevant  equitable  considerations.  The relative  fault will be  determined by
reference to whether the untrue or alleged  untrue  statement of a material fact
or omission or alleged  omission to state a material fact relates to information
supplied by the Indemnifying  Party on the one hand or the Indemnified  Party on
the other,  the intent of the parties and their  relative  knowledge,  access to
information  and  opportunity  to correct or prevent such statement or omission,
but not by reference to any  Indemnified  Party's stock ownership in the Issuer.
In no event,  however,  will a holder of  Registrable

CLCORP01 Doc: 230115_4                  22

<PAGE>

Securities  be  required to  contribute  in excess of the amount of the net
proceeds  received by such  holder in  connection  with the sale of  Registrable
Securities in the offering which is the subject of such loss,  claim,  damage or
liability. The amount paid or payable by an Indemnified Party as a result of the
loss,  claim,  damage or liability,  or action in respect  thereof,  referred to
above in this paragraph includes,  for purposes of this paragraph,  any legal or
other expenses  reasonably incurred by such Indemnified Party in connection with
investigating  or  defending  any such  action  or claim.  No  Person  guilty of
fraudulent  misrepresentation  (within  the  meaning  of  Section  11(f)  of the
Securities Act)) is entitled to contribution  from any Person who was not guilty
of such fraudulent misrepresentation.

          2.6 Information by Holders.  If Registrable  Securities  owned by a
Qualified Holder are included in any registration, such holder will furnish to
the Issuer such information regarding itself and the distribution proposed by
such holder as the Issuer may reasonably request and as is required in
connection with any registration, qualification or compliance referred to in
this Article 2.

          2.7 Rule 144 Reporting. With a view to making available to each
Qualified Holder the benefits of certain rules

CLCORP01 Doc: 230115_4                  23

<PAGE>

and  regulations  of the  Commission  which  may  permit  the  sale  of the
Registrable  Securities to the public  without  registration,  the Issuer agrees
that so long as a holder owns any Registrable Securities,  the Issuer shall, (a)
make and keep available public  information,  as those terms are contemplated by
Rule 144 under the  Securities  Act;  (b) timely  file with the  Commission  all
reports and other  documents  required to be filed under the  Securities Act and
the  Securities  Exchange Act of 1934 (the "Exchange  Act");  and (c) furnish to
each holder  forthwith upon request a written  statement by the Issuer as to its
compliance  with  the  reporting  requirements  of the  Securities  Act  and the
Exchange  Act,  a copy of the most  recent  annual  or  quarterly  report of the
Issuer,  and such other  information  as such holder may  reasonably  request in
order to avail itself of any rule or regulation of the Commission  allowing such
holder to sell any Registrable Securities without registration.

          2.8 Future Registration Rights.  (a)  The Issuer will not hereafter
agree with the holders of any securities issued or to be issued by the Issuer
to register such securities under the Securities Act unless such agreement
specifically provides that (i) such holder of securities may not participate in
any Piggyback Registration except as provided in Section 2.1, (ii)

CLCORP01 Doc: 230115_4                  24

<PAGE>

the  holder  of  such  securities  may  not  participate  in any  Requested
Registration  except as provided in Section 2.2,  (iii) unless in the opinion of
the managing underwriter or underwriters,  if any, of any Piggyback Registration
or Requested  Registration  the public offering or sale of such other securities
would not interfere with the successful  public offering and sale of Registrable
Securities requested to be included in such Piggyback  Registration or Requested
Registration,  such other  securities  will not be  included  in a  registration
statement in which such shares of Registrable  Securities  are so included,  and
(iv) such  securities  may not be  publicly  offered  or sold for a period of at
least  ninety  (90) days after the date upon which such  registration  statement
becomes  effective.  This  Section 2.8 is not  violated by the future  grants of
registration   rights   provided  such  rights  are  subject  to  the  foregoing
restrictions  and are  exercisable on a pro rata basis with all other holders of
such  rights,  and the Issuer is not be  required  to obtain the  consent of any
party hereto with respect to such future grants.

          (b) From and after the date hereof, the Issuer shall not enter into
any agreement with any holder or prospective holder of any securities of the
Issuer providing for the granting to such holder of registration rights
(including demand

CLCORP01 Doc: 230115_4                  25

<PAGE>

registration rights which, by their terms, do not permit the inclusion of
shares of parties other than the holders of such demand registration rights)
that entitle such holder to priority over a Qualified Holder with respect to
registration of the securities of the Issuer.

          2.9  Permitted Interruption.  Notwithstanding any provision of this
Article  2,  the  Issuer  shall  not  be  required  to  prepare  or  file a
registration  statement,   amendment  or  post-effective  amendment  thereto  or
prospectus  supplement or to supplement or amend any  registration  statement or
otherwise facilitate the resale of Registrable Securities,  and the Issuer shall
be free to take or omit to take  any  other  action  that  would  result  in the
impracticality  of any such filing,  supplement  or  amendment,  if such filing,
supplement or amendment (and any required disclosure therein), in the good faith
and  reasonable  judgment of the Issuer,  would  jeopardize  the completion of a
material  investment in the Issuer,  or any  acquisition,  divestiture  or other
similar transaction that the Issuer is at such time in negotiations therefor, so
long as the Issuer shall,  as promptly as  practicable  after the  conclusion of
such negotiations,  make such filing, supplement or amendment and so long as the
Issuer  shall,   as  promptly  as  practicable   thereafter,   comply  with  the
requirements

CLCORP01 Doc: 230115_4                  26

<PAGE>

of this  Article 2, if  applicable  (any period  described in this
Section  2.9 during  which the  Company  is not  required  to make such  filing,
amendment or supplement being herein a "Permitted Interruption"). If a Qualified
Holder has  requested  registration  of New Shares in a Requested  Registration,
Piggyback  Registration  or Cutback  Registration  and a Permitted  Interruption
affects that  registration,  the Issuer  agrees to notify each of the Holders so
affected  by  a  Permitted  Interruption  upon  each  of  the  commencement  and
termination of each Permitted Interruption.  The Issuer shall not be required in
the notice of a Permitted  Interruption to disclose the cause for such Permitted
Interruption. The Permitted Interruption terminates upon the termination of such
negotiations or the public disclosure thereof.

                                   Article 3

                                 MISCELLANEOUS

          3.1  Notices.  Except as otherwise specifically provided in this

<PAGE>

          3.2  Non-Waiver of Remedies and Actions By Holders.  No course of
dealing between the Issuer and any Qualified Holder or any delay on the part of
such holder in exercising any rights available to such holder operates as a
waiver of any right of such holder, except to the extent expressly waived in
writing by such holder.

          3.3  Headings.  The headings in this Agreement are for purposes of
reference only and are not to be considered in construing this Agreement.

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

          3.5  Successors and Assigns.  This Agreement binds and inures to the
benefit of the successors of any Qualified Holders and the Issuer.  Except for
Option Acquisition's right to designate up to two other Qualified Holders as
expressly provided herein, no Qualified Holder may assign any of the rights
created by this Agreement.

          3.6  Consent of Holders; Waiver.  (a)  Whenever, by the terms hereof,
anything is required to be done to the satisfaction of the Qualified Holders,
or such Holders are to appoint a

CLCORP01 Doc: 230115_4                  28

<PAGE>

representative, if such satisfaction, or appointment is necessary in connection
with a specific registration being effected hereunder, it will be effective
when done by the Qualified Holders holding a majority of the Registrable
Securities held by Qualified Holders that are being included in such
registration.

          (b) Except as provided in Section 3.6(a), whenever, by the terms
hereof,  the  consent of the  Qualified  Holders is  required,  anything is
required to be done to the satisfaction of such holders,  or if such holders are
to appoint a  representative,  such consent,  satisfaction,  or  appointment  is
effective when done by Qualified  Holders  holding a majority of the Registrable
Securities held by Qualified Holders.

          (c) All rights and remedies hereunder for the benefit of the
Qualified Holders are intended to be for the benefit of each holder of
Registrable Securities and, unless otherwise specified to the contrary, may be
exercised by the Qualified Holders together or by each such holder separately.

          3.7 Enforceability.  If any term or provision of this Agreement, or
the application thereof to any Person or circumstance, is, to any extent,
invalid or unenforceable, the remaining terms and provisions of this
Agreement or application to other Persons and circumstances are not invalidated
thereby,

CLCORP01 Doc: 230115_4                  29

<PAGE>

and each term and provision hereof is to be construed with all other remaining
terms and provisions hereof to effect the intent of the parties hereto to the
fullest extent permitted by law.

          3.8 Law Governing.  This Agreement is to be construed and enforced in
accordance with and shall be governed by the laws of the State of Delaware
applicable to contracts executed in and to be fully performed in that state.

          3.9  Effectiveness.  The effectiveness of this Agreement is
conditioned upon, and the obligations and rights of the parties hereunder will
come into force and effect at, the Closing as contemplated in the Option
Purchase Agreement.

          IN WITNESS WHEREOF, the parties hereto have caused this Agreement to
be duly executed and delivered as of the day and year first above written.

                          Registration Rights Agreement

          This is First Amendment to Registration Rights Agreement, dated as of
June 18, 1997, (this "Amendment") by and among Nextel Communications, Inc., a
Delaware corporation (the "Issuer"), Digital Radio, L.L.C., a Washington

                             Introductory Statement

Common Stock, par value $.001 per share ("Issuer Common Stock") acquired by
Option  Acquisition  upon the  exercise  of two options  being  issued to Option
Acquisition  on the date of this  Amendment (the "New Options") will be entitled
to the benefits of the Original  Agreement under certain  circumstances,  as set
forth in this Agreement.

                                      Agreement

          NOW, THEREFORE, in consideration of the foregoing, the covenants of
the Option Purchase Agreement and this Amendment, the parties agree as follows:

          1. Expand Definition of Registrable Securities.  Recital D of the
Original Agreement is hereby amended to delete the parentheses and
parenthetical text, and Section 1(ix) of the Original Agreement is hereby
amended to read in its entirety:

          (x) "Registrable Securities" means, except as otherwise stated in
     this Section (x), (A) Issuer Common Shares that the Investor and/or any of
     the Qualified Controlled Affiliates may purchase from the Issuer or
     receive upon conversion of any of its Issuer Preferred Shares or upon
     exercise of any of the Options; (B) Secondary Common Shares that the
     Investor and/or any of the Qualified Controlled Affiliates may purchase
     form Supplier

                                                                           3

     and Secondary Option Shares received upon exercise of the Supplier
     Option; and (C) Qualified New Option Shares; but does not include any
     other Issuer Common Shares or other securities of the Issuer which may
     now or hereafter be held or acquired by any holder of Registrable
     Securities.  Securities will cease to be Registrable Securities upon the
     first to occur of the following:  (i) such securities have been sold
     pursuant to a registration or pursuant to Rule 144 promulgated by the
     Securities and Exchange Commission (or any similar rule then in force);
     (ii) with respect to Issuer Common Shares issued upon exercise of the
     Incentive Stock Options, to the extent such securities have been
     previously registered if they may be resold by the holder thereof without
     registration or limitation; and (iii) such securities have been exchanged,
     substituted or replaced by securities which have been registered under the
     Securities Act.  For all purposes of this Agreement, a holder of
     Registrable Securities shall be deemed to hold any Registrable Securities
     issuable to such holder upon conversion or exercise of, or in exchange
     for, Convertible Securities of the types described in clause (A) or (B) of
     this Section (x), disregarding any legal, regulatory or

                                                                           4

     contractual restrictions on such conversion, exercise or exchange.

          2. Add Definition of Qualified New Option Shares.  Section 1(xiii) of
the Original Agreement is hereby renumbered to be Section 1(ix), Section 1(x)
is hereby renumbered Section 1(xi).  A new Section 1(viii) is added as follows:

          (viii) "Qualified New Option Shares" means Issuer Common Shares, if
     any, owned by Option Acquisition acquired as a result of the exercise of a
     New Option, except that (A) no such shares are Qualified New Option Shares
     until January 1, 1999, (B) any such shares shall cease being Qualified New
     Option Shares from and after the first day that Individual and/or Members
     of the McCaw Family (as defined in Section 4 of the First Amendment to
     Registration Rights Agreement dated as of June 16, 1997 among the Issuer,
     Investor and Option Acquisition) no longer control Option Acquisition, (C)
     no such shares are Qualified New Option Shares from and after the time
     that the number of Issuer Common Shares held by Option Acquisition is less
     than 1% of the outstanding Issuer Common Shares and the holding period
     under Rule 144 of the Securities Act applicable to Option Acquisition has
     been satisfied.

          3. Notices to Option Acquisition.  From and after January 1, 1999,
the Issuer will send to Option Acquisition (at the address specified for
notices under the Option Purchase Agreement) a copy of any notice that the
Issuer sends to the Investor under the Original Agreement (as amended by this
Amendment, and as the same may be further amended, the "Investor Registration
Rights Agreement").

          4. Change in Control of Option Acquisition. (a) If Option Acquisition
becomes aware that it is no longer controlled by Individual and/or Members of
the McCaw Family (as defined below), Option Acquisition will notify Issuer of
that fact and this Amendment will be void and without further force or effect.
Solely for purposes of the Introductory Statement (as it relates to control of
Option Acquisition) and Section 4 of this Amendment, and for purposes of
Section 1 (viii) (B) of the Original Agreement (as amended by this Amendment),
the terms "controls" and "controlled by" shall mean that Individual and/or
Members of the McCaw Family have the sole possession of at least 2/3 of the
voting and investment power over management and policies of Option Acquisition
including, without limitation, the sole authority to make all decisions with
respect to the Option Purchase Agreement and the purchase, sale and voting of
any

securities of the Company owned or available for purchase by Option
Acquisition pursuant to the Option Purchase Agreement and the New Options. For
purposes of Section 4 of this Amendment and Section 1(viii) of the Original
Agreement (as amended by this Amendment), "Members of the McCaw Family" means
Bruce R. McCaw, John E. McCaw, Keith O. McCaw, Marion O. Williams, their
respective lineal descendants, any entity controlled by any such persons
(including, without limitation, KMMK Limited Partnership), and any trust or
foundation established by any such persons that holds all or any part of
such persons' interests in Option Acquisition either during the lifetime or
upon the death of any such persons.

          (b) At any time that Option acquisition is exercising any rights as a
holder of Registrable Securities pursuant to the Investor Registration Rights
Agreement, the Issuer may require Option Acquisition and Individual (or a
Member of the McCaw Family if Individual is deceased on incapacitated at the
time) to certify that Individual and/or Members of the McCaw Family control
Option Acquisition. 

          5. Reaffirmation of Original Agreement.  Except as expressly stated
in this Amendment, the Original Agreement remains in full force and effect.

          IN WITNESS WHEREOF, the parties have caused this Amendment to be duly
executed on their behalf, as of the day and year first above written.

dated as of March 24, 1997 between  NEXTEL FINANCE  COMPANY,  a corporation
duly organized and validly existing under the laws of the State of Delaware (the

the "Restricted  Companies");  and THE CHASE MANHATTAN BANK, as collateral agent
for the Vendors and Lenders party to the Loan  Agreements  referred to below (in
such capacity,  together with its successors in such capacity,  the  "Collateral

     Nextel Communications, Inc. and the Restricted Companies are parties to
(i) an Amended,  Restated and  Consolidated  Credit  Agreement  dated as of
September  27, 1996 (as  modified  and  supplemented  and in effect from time to

Parties as required by Section 7.02(b) of the Restricted  Company  Guarantee and

follows:

     A.  References in the Restricted Company Guarantee and Security Agreement

amended to read in its entirety as follows:

     action from time to time as shall be necessary so that all leasehold and
     other real property interests of the Restricted Companies are

     subjected to Liens in favor of the Collateral Agent as collateral security
     for the Secured Obligations.  In that connection, the Restricted Companies
     will

          (a)  obtain appropriate consents of landlords, in form and substance
     satisfactory to the Collateral Agent, with respect to (i) 100% of all
     leasehold interests arising after the date hereof and used by any
     Restricted Company as a main switching site and (ii) 95% of all
     leasehold interests in properties used by the Restricted Companies as
     radio transmitter sites arising after the date hereof in each Market (as
     defined in Annex 4) in which a Restricted Company operates a Mobile
     Communications Business (but excluding, in the case of this clause
     (ii), (w) Analog Site Leases acquired in connection with an acquisition of
     a Mobile Communications Business consummated after the date hereof, (x)
     renewals and expansions of Analog Site Leases (as defined below) existing
     on the date hereof or acquired in connection with an acquisition of a
     Mobile Communications Business consummated after the date hereof and
     (y) new Analog Site Leases entered into after the date hereof with respect
     to real property subject to an Analog Site Lease existing on the date
     hereof or acquired in connection with an acquisition of a Mobile
     Communications Business consummated after the date hereof) and

          (b)  use its best efforts to obtain such consents with respect to all
     such leasehold interests existing on the date hereof and all such
     leasehold interests arising after the date hereof as to which consents are
     not required pursuant to the foregoing clause (a).

     In addition, each Restricted Company agrees (i) to use its reasonable best
     efforts, when entering into any new leases or acquiring any new leasehold
     interests after the date hereof, to cause such lease or leasehold interest
     (or a memorandum thereof) to be recorded prior to the time at which any
     Restricted Company places equipment on such leasehold interest and (ii)
     otherwise to comply with its obligations under the Collateral Assignment
     of Leasehold Interests dated as of September 27, 1996 by the Restricted
     Companies parties thereto in favor of the Collateral Agent, as modified
     and supplemented and in effect from time to time.

     As used in this Section 6.13, "Analog Site Lease" means any leasehold
     interest that is used by any Restricted Company as a radio transmitter
     site that employs solely analog technology."

     D.  The Restricted Company Guarantee and Security Agreement is hereby
amended by inserting a new Annex 4 thereto in the form of Annex 4 to this
Amendment No. 1 to Restricted Company Guarantee and Security Agreement.

represents  and warrants to the Secured  Parties and the  Collateral  Agent
that  the  representations  and  warranties  set  forth  in  Article  III of the
Restricted Company Guarantee and Security Agreement are true and complete on the
date  hereof  as if  made  on  and  as of  the  date  hereof  (or  if  any  such

necessary to conform to said sentence.

Company Guarantee and Security Agreement shall remain unchanged and in full
force and effect.  This  Amendment  No. 1 to  Restricted  Company  Guarantee and

No. 1 to Restricted  Company Guarantee and Security  Agreement shall be governed
by, and construed in accordance with, the law of the State of New York.

     subjected to Liens in favor of the Collateral Agent as collateral security
     for the Secured Obligations.  In that connection, the Restricted Companies

          substance satisfactory to the Collateral Agent, with respect to (i)
          100% of all leasehold interests arising after the date hereof and
          used by any Restricted Company as a main switching site and (ii) 95%
          of all leasehold interests in properties used by the Restricted
          Companies as radio transmitter sites arising after the date hereof in
          each Market (as defined in Annex 4) in which a Restricted Company
          operates a Mobile Communications Business (but excluding, in the case

               (b)  use its best efforts to obtain such consents with respect
          to all such leasehold interests existing on the date hereof and all
          such leasehold interests arising after the date hereof as to which
          consents are not required pursuant to the foregoing clause (a).

     In addition, each Restricted Company agrees (i) to use its reasonable best
     efforts, when entering into any new leases or acquiring any new leasehold
     interests after the date hereof, to cause such lease or leasehold interest
     (or a memorandum thereof) to be recorded prior to the time at which any
     Restricted Company places equipment on such leasehold interest and (ii)
     otherwise to comply with its obligations under the Collateral Assignment
     of Leasehold Interests dated as of September 27, 1996 by the Restricted
     Companies parties thereto in favor of the Collateral Agent, as modified
     and supplemented and in effect from time to time.

                    Nextel Now in Top 10 U.S. Markets

               - Company Announces Record Subscriber Growth,
                 Increased ARPU and Continued Low Churn -


McLEAN, Va., July 8, 1997 -- Nextel Communications, Inc. (NASDAQ: NXTL) today
announced the rollout of its enhanced all-digital wireless network in Houston.
With the addition of Houston, Nextel now serves more than 250 cities across the
United States and is currently positioned in twenty of the country's top
twenty-five markets. The company also noted that Oklahoma City and Tulsa
markets were added June 30.

Nextel also announced that it added a record 201,500 digital subscribers during
the second quarter of 1997, an increase of 64 percent over first quarter's
results when a record 122,600 digital subscriber units were added.  As of June
30, 1997, Nextel has approximately 624,400 digital subscriber units in service
across the Nextel National Network. The company also announced an increase in
the average monthly revenue per unit (ARPU) to approximately $63 in the second
quarter from $59 in the first quarter and continued to experience a low churn
rate in the second quarter of approximately one percent.

"As we continue the roll out of our national network, we are experiencing
record subscriber growth, increased ARPU and low churn.  These are the drivers
of success in wireless," said Tim Donahue, Nextel's president and chief
operating officer.  "We've added a total of  324,100 digital subscriber units
in 1997 alone.  And, I am confident that if we sustain this growth, we will
emerge as one of the true leaders in the wireless marketplace."

Nextel's record growth in the second quarter was helped by the launch of 8
major markets in early April, including New York, Los Angeles and Washington,
D.C., as well as by the initiation of the company's national television
advertising campaign.  A total of 14 markets were launched by the company in
the second quarter. Nextel expects to announce a few additional market launches
in the third quarter.

Nextel Communications, based in McLean, VA, is the nation's leading provider of
fully integrated wireless communications and has built the largest guaranteed
all-digital wireless network in the United States.  Nextel plans to cover 85
percent of where America's population lives or works by the end of 1998.  To
