2. REGISTRATION.

      (a) DEMAND REGISTRATION.  At any time and from time totime (i) if the
          Closing has  occurred  under the Merger  Agreement  on or prior to the
          date  hereof,  after 180 days  following  the  Closing  Date under the

          hereof, upon written request by the Requisite Holders that the Company
          effect the registration under the Securities Act of all or part of the
          Registrable  Securities  (a "Demand  Request"),  the Company  will use
          reasonable best efforts to register the Registrable  Securities  which
          the Company has been so requested to register by the Holders under the
          Securities Act for resale by the Holders in an  underwritten  offering
          (a  "Demand  Offering")  pursuant  to a  registration  statement  (the
          "Demand  Registration  Statement") that has been declared

                                      -2-



          effective by the Commission, which  registration  statement shall be
          kept effective  by the Company  until the earlier of such time as the
          Demand  Offering is completed or the  expiration of 60 days  following
          the effectiveness of the Demand Registration Statement;  provided that
          the Company shall not be obligated to effect a Demand Offering that is
          underwritten for Requisite Holders hereunder, but instead may effect a
          Demand  Offering  by  registering  resale  transactions   involving  a
          non-underwritten   distribution  of  Registrable  Securities,  if  the
          Registrable  Securities  sought to be included in such Demand Offering
          by such Requisite  Holders have an aggregate  Reference  Value of less
          than $30,000,000. The Company will use reasonable best efforts to have
          each  Demand   Registration   Statement   declared  effective  by  the
          Commission  within  ninety (90) days after  receipt of such request or
          within sixty (60) days after receipt of such request if the Company is
          qualified to file a registration statement on Commission Form S-3, S-2
          or  any  successor  or  similar  short-form   registration   statement
          (collectively, "Commission Form S-3"). Subject to subdivision (g), the
          Company may include in such Demand  Registration  Statement and Demand
          Offering  other  securities of the Company for sale, for the Company's
          account or for the  account  of any other  person.  Upon  receipt of a
          Demand Request, the Company shall promptly give written notice of such
          request  to all  Holders,  and  all  Holders  shall  be  afforded  the
          opportunity  to  participate  in such  request as follows:  subject to
          subdivision (f), the Company will include in each Demand  Registration
          Statement and Demand Offering such number of Registrable Securities of
          any Holder  joining  in such  request  as are  specified  in a written
          request by the Holder  received  by the  Company  within 20 days after
          receipt of such written notice from the Company.

     (b)  INCIDENTAL REGISTRATION.  For so long as  Registrable  Securities  are
          outstanding,  if the Company for itself or any of its security holders
          shall at any time or times after the date hereof determine to register
          under the  Securities  Act any  shares of its  capital  stock or other
          securities  (other than:  (i) the  registration  of an offer,  sale or
          other  disposition  of  securities  solely to  employees  of, or other
          persons providing services to, the Company, or any subsidiary pursuant
          to an  employee  or similar  benefit  plan;  or (ii) the  issuance  of
          securities in a merger,  acquisition or other  transaction of the type
          described  in Rule 145 under the  Securities  Act or a  comparable  or
          successor rule, registered on Form S-4 or similar or successor forms),
          on  each  such  occasion  the  Company  will  notify  each  Holder  of
          Registrable Securities of such determination at least thirty (30) days
          prior  to the  filing  of such  registration  statement,  and upon the
          request of any Holder given in writing  within  twenty (20) days after
          the  receipt  of  such  notice,  the  Company  will  cause  any of the
          Registrable  Securities specified by any such Holder to be included in
          such  registration  statement  to  the  extent  such  registration  is
          permissible  under the Securities Act and subject to the conditions of
          the Securities Act and subdivision (g) (an "Incidental Registration").

     (c)  REGISTRATION STATEMENT FORM.  The Company shall,  if permitted by law,
          effect any  registration  requested under Section 2 by the filing of a
          registration statement on Commission Form S-3.

     (d)  EXPENSES.  The Company shall pay all Registration Expenses incurred in
          connection with any Demand  Registration  Statement and any Incidental
          Registration  Statement.   Those  Holders  of  Registrable  Securities
          participating  in any Demand

                                      -3-



          Offering and any Incidental Registration shall bear their respective
          pro  rata  share  of  any   applicable   underwriting   discounts  and
          commissions;  such  participating  Holders  agree  that  the  proceeds
          received by them upon  consummation  of any such offering shall be net
          of any and all such discounts and commissions.

     (e)  EFFECTIVE REGISTRATION STATEMENT.   Neither   a  Demand   Registration
          Statement,  nor an Incidental  Registration requested pursuant to this
          Section 2 shall be deemed to have been  effected  until it has  become
          effective  with  the  Commission.  Notwithstanding  the  foregoing,  a
          registration  statement  will not be deemed to have been  effected if:
          (i)  after  it  has  become   effective  with  the  Commission,   such
          registration  is  interfered  with by any stop order,  injunction,  or
          other order or  requirement  of the  Commission or other  governmental
          agency  or  any  court   proceeding   for  any  reason  other  than  a
          misrepresentation or omission by any Holder; or (ii) the conditions to
          consummation  of any Demand  Offering  contained  in the  underwriting
          agreement  entered into in connection with such  registration  are not
          satisfied,  other than solely by reason of some act or omission by any
          Holder.

     (f)  PRIORITY IN UNDERWRITTEN REGISTRATIONS.  If a  registration  is  an
          underwritten  registration and the managing  underwriters give written
          advice to the  Company and the Persons  requesting  such  registration
          that, in their opinion,  market conditions dictate that no more than a
          specified maximum number of securities could  successfully be included
          in such registration,  then the maximum number of securities  included
          in such  registration  statement  shall be limited  to such  specified
          number,  and  the  rights  of  the  Holders  to  participate  in  such
          registration will the subject to the following cutback provisions:

          (i)  In the case of the initial Demand Offering, the securities sought
               to be included in such offering by the Holders shall be excluded
               on a pro rata basis with the securities sought to be included in
               the Demand Offering by the Company and all other Persons seeking
               inclusion of securities in such offering (including pursuant to
               so-called piggyback registration rights), based upon the
               Holder's, the Company's and the other Persons' relative number
               of securities sought to be so included until the aggregate market
               value of the securities sought to be included in such offering by
               the Holders has been reduced to a number of shares constituting
               Registrable Securities equal to (A) 70% of the amount of the
               Registrable Securities initially subject to this Agreement less,
               if any portion of the Remaining Purchase Price under the Purchase
               Agreement was paid in cash ("Cash Payment"), (B) a number of
               shares constituting Registrable Securities given by the following
               formula:  X/Y, where X is the amount of the Cash Payment and Y is
               the Reference Value (as adjusted for stock splits, stock
               dividends, recapitalizations or similar events), after which any
               additional securities required to be excluded from such offering
               in order to comply with the advice of the managing underwriter
               shall be securities that were to have been offered for the
               Company's account until the offering includes no such securities,
               after which the securities sought to be included in such offering
               by the Holders shall be excluded on a pro rata basis with the
               securities sought to be included in the Demand Offering by all
               other Persons seeking inclusion of securities in such offering
               (including pursuant to so-called piggyback registration rights),
               based upon the

                                      -4-



               Holder's and the other Persons' relative number of securities
               sought to be so included; and

         (ii)  If the  registration is an Incidental  Registration, (a) the
               securities  sought to be registered by the Company for its own
               account shall have priority for inclusion,  (b) the securities
               sought to be registered for the account of other Persons
               exercising  demand  registration  rights shall have priority for
               inclusion to the extent such rights  require such priority and
               (c) Registrable Securities held by the Holders may be  excluded
               on a pro rata  basis  with all other  Persons seeking  inclusion
               of  securities  in such  registration  pursuant to the  exercise
               of so-called piggyback  registration  rights,  based upon such
               Holder's and other Persons'  relative number of securities sought
               to be so included.

     (g)  BLACKOUT AND POSTPONEMENT.  Notwithstanding anything in paragraphs (a)
          and (b) of this  Section  2, the  Company  shall have the right (i) to
          delay any registration of Registrable Securities requested pursuant to
          paragraph (a) or (b) of this Section 2 or (ii) upon written  notice to
          the  Holders,   to  prohibit  the  Holders  from  selling  Registrable
          Securities under any Demand  Registration  Statement or any Incidental
          Registration,  in any case for up to 120 days if such  registration or
          sale,  as  applicable,  would,  in  the  judgment  of the  Company  as
          reflected  in an  officer's  certificate  delivered  to  the  Holders,
          require  disclosures  that would not be in the Company's best interest
          to  make  at  such  time,  as  applicable;   provided,  however,  that
          registrations  shall not be delayed and/or sale prohibitions  relating
          to offerings shall not be in effect pursuant to the provisions of this
          paragraph  (g) for more than 270 days  during  any period of 365 days.
          The time period during which any sale prohibition relating to a Demand
          Registration  Statement  is in effect under this Section 2(g) shall be
          added to the time period for which a Demand Registration  Statement is
          otherwise required to remain effective under this Agreement.

               such registration statement and to require the insertion therein
               of material, furnished to the Company in writing,  which in the
               reasonable  judgment of such Holder and its counsel  should be
               included and which is not reasonably objected to by the Company

               methods of disposition  by the seller or sellers  thereof set
               forth in such  registration  statement or the  expiration of 60

               sold under registration statement shall reasonably  request,  to
               keep such registration or qualification in effect for so long as

               included in such registration  statement  for sale in any

                                      -6-


               of such  registration, addressed to the  underwriters, if  any,
               and to the  Holders  making  such  request,  stating  that  such
               registration  statement has become  effective  under the
               Securities Act and that (i) to the best knowledge of such
               counsel,  no stop order  suspending the  effectiveness  thereof
               has been issued and no proceedings  for that purpose have been
               instituted or are pending or  contemplated  under the Securities
               Act; (ii) the registration statement,  the related prospectus,
               and each amendment or supplement  thereto,  comply as to form in
               all material  respects with the requirements of the Securities
               Act and the applicable  rules and  regulations of the Commission
               thereunder  (except that such counsel need express no opinion as
               to financial statements and related schedules and other projected
               financial or statistical  data contained  therein);  (iii) the
               descriptions in the  registration  statement or the prospectus,
               or any amendment or supplement  thereto,  of all legal and
               governmental  matters and  contracts  and other legal  documents
               or  instruments  are accurate and fairly present the information
               required to be shown;  and (v) such counsel does not know of any
               legal  or  governmental  proceedings,  pending  or  contemplated,
               required  to be described in the registration  statement or
               prospectus,  or any amendment or supplement  thereto, which are
               not  described as required  nor of any  contracts  or  documents
               or instruments of a character  required  to be  described  in
               the  registration  statement  or  prospectus,  or  any amendment
               or supplement  thereto or to be filed as exhibits to the
               registration  statement which are not  described  and filed as
               required.  Such counsel  shall also opine that, in the course of
               assisting  the  Company  in  preparing  the  Registration
               Statement,  nothing  has come to their attention  that would
               cause them to  believe  that the  Registration  Statement
               (excluding  the financial and  statistical  information
               contained  therein)  contains any untrue statement of a material
               fact or omits a material fact  necessary to make the  statements
               therein,  in light of the circumstances under which they were
               made not misleading.

          (ix) furnish  to the  Holders of  Registrable  Securities  to be sold
               under the  Registration Statement  a letter, dated the effective
               date  of  the  registration  statement, from the independent
               certified public accountants of the Company,  addressed to the
               underwriters,  if any, and to the Holders  making such  request,
               stating  that they are independent certified  public accountants
               within  the  meaning  of the  Securities  Act  and  that in the
               opinion  of  such accountants,  the financial  statements and
               other financial data of the Company included in the registration
               statement or the prospectus,  or any amendment or supplement
               thereto, comply as to form in all material  respects with the
               applicable  accounting  requirements  of the  Securities  Act.
               Such letter from the independent  certified  public  accountants
               shall  additionally  cover such other financial  matters
               (including  information as to the period ending not more than
               five business  days prior to the date of such letter) with
               respect to the  registration  in respect of which such letter is
               being given as the Holders may reasonably request.

           (x) immediately notify the Holders of Registrable Securities included
               in such registration statement at any time when a prospectus
               relating  thereto is required to be delivered  under the
               Securities Act, of the happening of any event as a result of
               which the  prospectus included in such registration  statement,
               as then in effect,

                                      -7-



               includes an untrue statement of material fact or omits to state
               any  material  fact  required  to be stated  therein or
               necessary  to make the statements  therein not misleading in the
               light of the circumstances  under which they were made, and at
               the request of the  Holders  promptly  prepare  and  furnish to
               the  Holders a  reasonable number of copies of a supplement  to
               or an amendment  of such  prospectus  as may be necessary so
               that, as thereafter  delivered to the purchasers of such
               securities, such prospectus shall not include 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
               not  misleading in the light of the circumstances under which
               they were made;

          (xi) otherwise use all  reasonable  best  efforts to comply  with all
               applicable  rules and regulations  of the  Commission, and  make
               available  to  its  security  holders,  as  soon  as reasonably
               practicable,  an earnings  statement  covering the period of at
               least twelve  months, but not more than  eighteen  months,
               beginning  with the first  full  calendar  month  after the 
               effective  date of such  registration  statement,  which
               earnings  statement  shall  satisfy the provisions  of Section
               11(a) of the  Securities  Act and Rule 158  thereunder,  and not
               file any amendment or  supplement to such registration statement
               or prospectus to which any Holder shall have  reasonably objected
               in writing on the grounds that such  amendment or supplement does
               not comply in all material  respects with the  requirements  of
               the Securities Act or of the rules or regulations  thereunder,
               having been  furnished  with a copy thereof at least two business
               days prior to the filing thereof to the extent reasonably
               possible;

         (xii) provide a transfer agent for all Registrable Securities covered
               by such registration statement not later than the effective date
               of such registration statement;

        (xiii) use all  reasonable  best  efforts  to cause to be  quoted  or
               listed  all  Registrable Securities  covered by such
               registration  statement  on NASDAQ and any  securities  exchange
               on  which any of the Registrable Securities are then quoted or
               listed;

         (xiv) confer with NSAC as to mutually beneficial and appropriate time
               to schedule the first Demand  Offering  and  make  available the
               Company's  management  to  participate in roadshow presentations
               and conference calls with respect to such offerings; and 

          (xv) confer with NSAC as to mutually beneficial and  appropriate time
               to schedule any other underwritten  offerings of Company Common
               Stock that will include Registrable  Securities and use all
               reasonable  best efforts to work with NSAC to schedule such
               offerings so that the Company's management  will be able to
               participate  in roadshow presentations and conference calls with
               respect to any additional  Demand  Offerings in excess of $100
               million,  the  availability of its senior management, however,
               being subject to conflicting business necessities.

                                      -8-



     (b)  As a condition  to the  Company's  obligation  under this Section with
          respect  to any  Holder,  the  Company  may  require  such  Holder  of
          Registrable  Securities to be sold under such registration  statement,
          at the Company's expense, to furnish the Company with such information
          and  undertakings as it may reasonably  request  regarding such Holder
          and the  distribution  of such securities as the Company may from time
          to time reasonably request in writing.

     (c)  Each  Holder,  by execution  of this  Agreement,  agrees (A) that upon
          receipt of any notice of the Company of the  happening of any event of
          the kind  described  in  subdivision  (a)(x) of this  Section  3, such
          Holder will  forthwith  discontinue  its  disposition  of  Registrable
          Securities  pursuant to the  registration  statement  relating to such
          Registrable  Securities until the receipt by such Holder of the copies
          of the supplemented or amended prospectus  contemplated by subdivision
          (a)(x) of this  Section 3 and,  if so directed  by the  Company,  will
          deliver to the Company all copies (other than  permanent file copies),
          then in possession of the Holders of the  prospectus  relating to such
          Registrable  Securities  current at the time of receipt of such notice
          and (B) that it will immediately notify the Company,  at any time when
          a  prospectus   relating  to  the  registration  of  such  Registrable
          Securities is required to be delivered  under the  Securities  Act, of
          the happening of any event as a result of which information previously
          furnished  in writing by such Holder to the Company for  inclusion  in
          such  prospectus  contains an untrue  statement of a material  fact or
          omits to state any  material  fact  required  to be stated  therein or
          necessary to make the  statements  therein not misleading in the light
          of the  circumstances  under  which they were  made.  In the event the
          Company  or any such  Holder  shall give any such  notice,  the period
          referred  to in  subdivision  (a)(iii)  of this  Section  3  shall  be
          extended  by a number of days equal to the  number of days  during the
          period from and including the giving of notice pursuant to subdivision
          (a)(x) of this  Section 3 to and  including  the date when such Holder
          shall  have  received  the  copies  of  the  supplemented  or  amended
          prospectus contemplated by subdivision (a)(x) of this Section 3.

4.  UNDERWRITTEN OFFERINGS.

     (a)  UNDERWRITTEN OFFERING.  In connection with any  underwritten  offering
          pursuant to a  registration  under  Section 2, the Company  will enter
          into  an  underwriting   agreement  with  the  underwriters  for  such
          offering,  such  agreement  to be in  form  and  substance  reasonably
          satisfactory  to all Holders  requesting  such  registration  and such
          underwriters  in  their  reasonable   judgment  and  to  contain  such
          representations  and warranties by the Company and such other terms as
          are  customarily  contained  in  agreements  of that type,  including,
          without  limitation,  indemnities  to the  effect  and  to the  extent
          provided  in  Section  5.  Each such  Holder  shall be a party to such
          underwriting agreement and may, at its option, require that any or all
          of the  representations and warranties by, and the other agreements on
          the part of, the Company to and for the  benefit of such  underwriters
          shall also be made to and for the benefit of each such Holder and that
          any or all of the  conditions  precedent  to the  obligations  of such
          underwriters under such underwriting agreement be conditions precedent
          to the obligations of each such Holder. No Holder shall be required to
          make any  representations  or  warranties  to or  agreements  with the
          Company or the underwriters other than representations,  warranties or
          agreements

                                      -9-




          regarding such Holder and its intended method of distribution and any
          other representation required by law.

     (b)  SELECTION OF  UNDERWRITERS.  The Company  shall  select its  customary
          underwriter  or,  alternatively,  an  underwriting  firm  of  national
          reputation,  with  expertise  in  comparable  offerings  by  companies
          engaged  in  businesses  similar  to  that  of  the  Company  that  is
          reasonably  satisfactory  to NSAC,  for any  Demand  Offering  and any
          underwritten offering pursuant to an Incidental Registration.

     (c)  HOLDBACK AGREEMENTS.  Each Holder agrees,  if required by the managing
          underwriter  in any  offering,  not  to  effect  any  public  sale  or
          distribution  of  Registrable  Securities,  any  sale or  distribution
          thereof  pursuant to Rule 144 or 145 under the Securities  Act, or any
          short sale thereof or any transaction or series of transactions having
          a substantially  similar  economic effect during the period  beginning
          (i) if the Closing under the Merger Agreement has occurred on or prior
          to the date hereof, on the date hereof and ending on the date 180 days
          after the Initial  Registration  Statement (as defined in that certain
          Registration   Rights   Agreement   between   Purchaser   and  certain
          stockholders  of WNP  Communications,  Inc.,  dated  January 14, 1999)
          shall have been  declared  effective or (ii) in the case of any Demand
          Registration or Incidental Registration, beginning seven days prior to
          the effective date of such registration  statement,  and ending on the
          date 180 days after any such  registration  statement  shall have been
          declared effective.

     (d)  PREPARATION, REASONABLE INVESTIGATION.

               In   connection  with  the  preparation  and  filing  of each
          registration  statement  under the  Securities  Act,  the Company will
          give Nextel, the underwriters, if any, and their respective counsel
          and accountants, drafts and final copies of such registration
          statement, each prospectus included therein or filed with the
          Commission and each amendment  thereof or  supplement  thereto,  at
          least 5 business  days prior to the filing thereof with the
          Commission, and will give each of them such access to its books and
          records  and such  opportunities  to discuss  the  business  of the
          Company  with  its  officers  and  the independent  public
          accountants  who  have  certified  its  financial statements as shall
          be necessary,  in the opinion of such Holders' and such  underwriters'
          respective  counsel,  to  conduct  a  reasonable investigation within
          the meaning of the Securities Act.


5. INDEMNIFICATION AND CONTRIBUTION.

     (a)  INDEMNIFICATION BY THE COMPANY. In the event of any registration under
          the Securities Act pursuant to Section 2 of any Registrable Securities
          covered by such  registration,  the  Company  will,  and hereby  does,
          indemnify and hold harmless each Holder of  Registrable  Securities to
          be sold under such  registration  statement,  each such Holder's legal
          counsel,  each other person who  participates as an underwriter in the
          offering  or  sale  of  such   securities  (if  so  required  by  such
          underwriter as a condition to including the Registrable  Securities of
          the Holders in such  registration)  and each other person, if any, who
          controls any such Holder or any such underwriter within the meaning


                                      -10-



          of the Securities Act (collectively, the "Indemnified Parties"),
          against any losses, claims, damages or liabilities, joint or several,
          to which the Holders or underwriter  or  controlling  person may
          become subject under the Securities Act or otherwise, insofar as such
          losses, claims, damages or liabilities (or actions or proceedings,
          whether  commenced or threatened,  in respect thereof) arise out of or
          are based upon any untrue statement or alleged untrue statement of any
          material  fact  contained in any  registration  statement under which
          such securities  were   registered   under  the Securities Act,  any
          preliminary  prospectus,  final prospectus or summary prospectus
          contained  therein  or  any  document   incorporated   therein  by
          reference,  or  any  amendment  or  supplement  thereto, or  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 arise out of  any  violation  by the
          Company  of  any  rule  or  regulation   promulgated  under  the
          Securities Act or state  securities law applicable   to the Company
          and  relating  to action or  inaction  required of  the Company in
          connection  with  any such  registration,  and  the  Company  will
          reimburse  the  Indemnified  Parties  for any  legal  or any other
          expenses   reasonably   incurred  by  them  in  connection   with
          investigating  or  defending  any such  loss,  claim,  liability,
          action or proceeding;  provided,  however, that  the Company shall
          not be  liable to any  Indemnified  Party  in  any such case to the
          extent that any such loss, claim, damage,  liability (or action or
          proceeding  in respect  thereof)  or expense  arises out of or is
          based upon any untrue  statement or alleged   untrue  statement or
          omission or alleged omission made in such   registration statement,
          any  such  preliminary  prospectus,  final   prospectus,   summary
          prospectus,  amendment  or  supplement  in   reliance   upon and in
          conformity with written  information  furnished to  the Company by
          such Indemnified Party specifically for use therein.

     (b)  INDEMNIFICATION BY THE HOLDERS.   The  Company  may   require,   as  a
          condition to including any Registrable Securities of any Holder in any
          registration  statement  filed pursuant to Section 2, that the Company
          shall have received an undertaking reasonably  satisfactory to it from
          such Holder to indemnify  and hold harmless (in the same manner and to
          the same extent as set forth in subdivision (a) of this Section 5) the
          Company, each director of the Company, each officer of the Company and
          each other person, if any, who controls the Company within the meaning
          of the  Securities  Act,  with  respect  to any  statement  or alleged
          statement in or omission or alleged  omission  from such  registration
          statement,  any preliminary  prospectus,  final  prospectus or summary
          prospectus  contained therein, or any amendment or supplement thereto,
          if,  and only if,  and only to the  extent  that,  such  statement  or
          alleged statement or omission or alleged omission was made in reliance
          upon and in conformity  with  information  furnished in writing to the
          Company  directly  by  such  Holder   specifically  for  use  therein;
          provided,  however,  that the obligation of any Holder hereunder shall
          be limited to an amount  equal to the net  proceeds  received  by such
          Holder upon the sale ofRegistrable Securities sold in the offering
          covered by such registration.

     (c)  NOTICES OF CLAIMS, ETC.   Promptly   after   receipt  by  an 
          Indemnified  Party  of  notice  of the  commencement  of any action
          or  proceeding  involving a claim  referred to in the preceding
          subdivisions of this Section 5, such  Indemnified Party  will,  if a
          claim in  respect  thereof  is to be made against a party  required
          to  provide  indemnification  (an "Indemnifying  Party"), give
          written notice to the latter of the commencement of such

                                      -11-



          action,  provided,  however,  that the failure of any Indemnified
          Party  to give  notice  as  provided  herein  shall  not  relieve  the
          Indemnifying Party of its obligation under the preceding  subdivisions
          of this Section 5, except to the extent that the Indemnifying Party is
          actually  prejudiced by such failure to give notice.  In case any such
          action  is  brought  against  an  Indemnified  Party,  unless  in such
          Indemnified Party's reasonable judgment a conflict of interest between
          such Indemnified and indemnifying parties may exist in respect of such
          claim, the Indemnifying  Party shall be entitled to participate in and
          to assume the defense  thereof,  jointly  with any other  Indemnifying
          Party similarly  notified to the extent that it may wish, with counsel
          reasonably  satisfactory to such  Indemnified  Party, and after notice
          from the Indemnifying  Party to such Indemnified Party of its election
          so to assume the defense thereof,  the Indemnifying Party shall not be
          liable  to such  Indemnified  Party  for any  legal or other  expenses
          subsequently  incurred  by the latter in  connection  with the defense
          thereof other than reasonable costs of investigation.  No Indemnifying
          Party  shall  consent  to entry  of any  judgment  or  enter  into any
          settlement without the consent of the Indemnified Party which does not
          include as an unconditional term thereof the giving by the claimant or
          plaintiff to such Indemnified Party of a release from all liability in
          respect to such claim or litigation.

     (d)  OTHER INDEMNIFICATION.   Indemnification  substantially equivalent to
          that  specified in the preceding  subdivisions  of this Section 5
          (with  appropriate  modifications)  shall be given by the  Company and
          each Holder of  Registrable  Securities  included in any  registration
          statement  with  respect  to  any  required   registration   or  other
          qualification  of  securities  under  any  Federal  or  state  law  or
          regulation of any  governmental  authority,  other than the Securities
          Act.

      (e) INDEMNIFICATION PAYMENT. The indemnification required by this Section
          5 shall be made by  periodic  payments  of the amount  thereof
          during the course of the  investigation or defense,  as and when bills
          are received or expense, loss, damage or liability is incurred.

      (f) SURVIVAL OF OBLIGATIONS.  The  obligations  of the Company and of the
          Holders under this Section 5 shall survive the completion of any
          offering of Registrable Securities under this Agreement.

      (g) CONTRIBUTION.  If  the  indemnification  provided  for  in  this
          Section 5 is  unavailable  or  insufficient  to hold  harmless an
          Indemnified  Party, then each  Indemnifying  Party shall contribute to
          the amount  paid or payable to such  Indemnified  Party as a result of
          the losses, claims, damages or liabilities referred to in this Section
          5 an  amount  or  additional  amount,  as the  case  may  be,  in such
          proportion  as is  appropriate  to reflect the  relative  fault of the
          Indemnifying  Party or  parties  on the one  hand and the  Indemnified
          Party on the other in  connection  with the  statements  or  omissions
          which resulted in such losses,  claims, demands or liabilities as well
          as any other  relevant  equitable  considerations.  The relative fault
          shall be determined  by reference to, among other things,  whether the
          untrue or alleged untrue  statement of a material fact or the omission
          or alleged  omission to state a material  fact relates to  information
          supplied by the  Indemnifying  Party or parties on the one hand or the
          Indemnified  Party on the other  and the  parties' relative,  intent,
          knowledge, access to information and opportunity to correct or prevent
          such untrue  statement or omission.  The amount paid to an Indemnified
          Party as a result of the losses,

                                      -12-


          claims,  damages or liabilities referred to in the first sentence of
          this  Section  5(g) shall be deemed to  include  any legal or other
          expenses  reasonably  incurred by such Indemnified Party in connection
          with  investigating  or  defending  any  action or claim  which is the
          subject   of  this   Section  5.  No  person   guilty  of   fraudulent
          misrepresentation   within  the  meaning  of  Section   11(f)  of  the
          Securities Act shall be entitled to  contribution  from any Person who
          was not guilty of such fraudulent misrepresentation.

6.  COVENANTS RELATING TO RULE 144.

               With a view to making available the benefits of certain rules and
          regulations of the Commission which may at any time permit the sale of
          securities  of the Company to the public  without  registration  after
          such  time as a  public  market  exists  for the  Common  Stock of the
          Company, the Company agrees:

          (a) to make and keep public information available, as those terms
          are understood  and defined in Rule 144 under the  Securities  Act, at
          all times after the date of the Closing;

          (b) to use all  reasonable  best  efforts  to then  file with the
          Commission in a timely manner all reports and other documents required
          of the  Company  under the  Securities  Act and the  Exchange  Act, as
          amended; and

          (c) so long as a  Holder  owns  any  Registrable  Securities,  to
          furnish to the Holder  forthwith  upon request a written  statement by
          the Company as to its compliance  with the reporting  requirements  of
          said Rule 144 and of the  Securities  Act and the Exchange Act, a copy
          of the most recent annual or quarterly report of the Company, and such
          other reports and documents of the Company as a Holder may  reasonably
          request in availing itself of any rule or regulation of the Commission
          allowing a Holder to sell any such securities without registration.

7. OTHER REGISTRATION RIGHTS.

               The Company  represents  and warrants that it has not granted any
          registration  rights to any Person other than as described pursuant to
          the Purchase Agreement.  The Company shall not grant to any Person any
          registration  rights  inconsistent with any of those contained herein,

          in effect.

8. MISCELLANEOUS.

          (a) SPECIFIC PERFORMANCE.  The parties hereto  acknowledge  that
          there may be no  adequate  remedy at law if any party fails to perform
          any  of  its  obligations   hereunder  and  that  each  party  may  be
          irreparably  harmed by any such failure,  and  accordingly  agree that
          each  party,  in  addition  to any  other  remedy  to  which it may be
          entitled at law or in equity,  shall be  entitled  to compel  specific

          construed in  accordance  with the  internal  laws of the State of New
          York, without regard to conflicts of law principles thereof.

          (d) HEADINGS.  The descriptive  headings of the several  sections
          and  paragraphs of this Agreement are inserted for  convenience  only,
          and do not constitute a part of this Agreement and shall not affect in
          any way the meaning or interpretation of this Agreement.

          (e)  ENTIRE AGREEMENT; AMENDMENTS.  This  Agreement and the other
          writings referred to herein or delivered  pursuant hereto which form a
          part hereof  contain  the entire  understanding  of the  parties  with
          respect to its subject  matter.  This  Agreement  supersedes all prior
          agreements and understandings  between the parties with respect to its
          subject  matter.  This  Agreement may be amended and the observance of
          any term of this  Agreement  may be waived  (either  generally or in a
          particular instance and either retroactively or prospectively) only by
          a written instrument duly executed by the Company and Nextel on behalf
          of the Holders. Each Holder of any Registrable  Securities at the time
          or  thereafter  outstanding  shall be bound by an  amendment or waiver
          authorized by this Section 8(e),  whether or not any such  Registrable

          (f)  ASSIGNABILITY.  This  Agreement  and  all of the  provisions
          hereof will be assigned,  without the consent of the  Company,  by any

          transferee  or assignee of any  Registrable  Security to the extent of
          the securities so  transferred or assigned,  provided that the seller,
          transferor  or  assignor  does  not  affirmatively  restrict  in -461-
          writing the transfer or assignment of rights hereunder with respect to
          such  securities.  However,  the  Company  shall  not be  required  to
          recognize any such purchaser, transferee or assignee as a Holder under
          this  Agreement  unless and until  either (i) such person  becomes the
          holder of record of Series A Common Stock or (ii) the Company receives
          written notice of such purchase,  transfer or assignment and a written
          agreement by the purchaser,  assignee or transferee to be bound by the
          provisions of this Agreement.

          (g)  COUNTERPARTS.  This Agreement may be executed in two or more
          counterparts,  each of which shall be deemed an  original,  but all of

               (h) STOCK SPLITS,  ETC. If the Company at any time subdivides (by
          any stock split,  stock dividend,  recapitalization  or otherwise) its
          outstanding  shares of Common Stock into a greater number of shares or
          if the  outstanding  shares  of Common  Stock  shall be  combined  (by
          reverse stock split or otherwise) into a smaller number of shares, all
          numbers,  percentages,  computations  and the  like in this  Agreement
          shall be deemed  modified as necessary to give  appropriate  effect to
          such subdivision or combination.

     IN WITNESS  WHEREOF,  the parties have  executed this  Registration  Rights
Agreement as of the date first above written.
