         WHEREAS,  the Company  and the  Trustee  heretofore  executed  and
delivered  an  Indenture,  dated as of August 15, 1993, as heretofore amended

         WHEREAS,  pursuant to the  Indenture,  the  Company  issued and the
Trustee  authenticated  and  delivered $525,855,000  aggregate  principal
amount at maturity of the Company's Senior  Redeemable  Discount Notes due 2003

         WHEREAS,  the Company has  delivered,  or caused to be  delivered, to

                                 ARTICLE 1
               WAIVERS OF CERTAIN PROVISIONS OF INDENTURE

         Section 1.01.  Waiver of Compliance with Certain Provisions of the
Indenture in  Connection With the Clearnet Transfer.  Subject to Section 3.01
hereof,  compliance by the Company with Section 1010 of the Indenture
(including  clause (iv) of the first  paragraph thereof),  to the extent that
such Section would apply to limit the ability of the Company to transfer all of
the capital  stock of Clearnet  that is held  directly by the Company on the
date hereof to McCaw  International,  Ltd. ("MIL"), a wholly owned Unrestricted
Subsidiary of the Company, or to any direct or indirect wholly owned subsidiary
of MIL that is  designated by MIL as the intended recipient of such equity
interest in Clearnet,  is hereby  waived.  As a result of such waiver, any such
transfer shall not be deemed a Restricted Payment under Section 1010 of the
Indenture.

                                  ARTICLE 2
                AMENDMENTS TO CERTAIN PROVISIONS OF INDENTURE

         Section 2.01.  Amendment of Certain Sections of the Indenture. Subject
to Section 3.01 hereof, the Indenture is hereby amended in the following
respects:

          (a) The  definition  of "Credit  Facility"  contained in  Section 101
     of the Indenture is hereby amended to read in its entirety as follows:

                 "'Credit  Facility' means any credit facility (whether a term
          or revolving type) of the type customarily entered into with banks,
          between the  Company  and/or any of its  Restricted Subsidiaries, on
          the one  hand, and any  banks or other lenders, on the other hand
          (and any renewals, refundings, extensions or replacements of any such
          credit facility), which credit facility is designated by the Company
          as a "Credit  Facility" for purposes of this Indenture, to the extent
          that the aggregate  principal  balance of Debt that is Incurred and
          outstanding under all Credit Facilities at any time does not exceed
          $1,905,000,000."

          (b) The  definition of "Incur" contained in Section 101 of the
     Indenture is hereby amended to read in its entirety as follows:

                 "'Incur' means, with respect to any Debt or other obligation
          of any Person, to create, issue, incur (by conversion, exchange or
          otherwise), assume (pursuant to a merger, consolidation, acquisition
          or other transaction), Guarantee or otherwise become liable in
          respect of such Debt or other obligation or the recording, as
          required  pursuant to generally accepted  accounting  principles  or
          otherwise, of any such Debt or other obligation on the balance sheet
          of such Person (and "Incurrence", "Incurred", "Incurrable" and
          "Incurring" shall have meanings correlative to the foregoing);
          provided,  however,  that a change in generally accepted accounting
          principles that results in an obligation of such Person that exists
          at such time becoming Debt shall not be deemed an Incurrence of such
          Debt; provided further, however, that the accretion of original issue
          discount on Debt shall not be deemed to be an  Incurrence of Debt.
          Debt otherwise Incurred by a Person before it becomes a Subsidiary of
          the Company shall be deemed to have been Incurred at the time it
          becomes such a Subsidiary."

          (c) The definition of "Investment" contained in Section 101 of the
     Indenture is hereby amended to read in its entirety as follows:

                "'Investment' by any Person means any direct or indirect loan,
          advance or other extension of credit or capital contribution to (by
          means of transfers of cash or other property to others or payments
          for property or services for the account or use of others,  or
          otherwise), or purchase or acquisition  of Capital Stock,  bonds,
          notes, debentures or other securities or evidence of Debt issued  by,
          any other Person; provided that a transaction will not be an
          Investment to the extent it involves (i) an Asset  Disposition,
          (ii) the issuance or sale by the Company of its Capital Stock (other
          than  Disqualified  Stock), including options, warrants or other
          rights to acquire such Capital Stock (other than  Disqualified Stock)
          or (iii) a transfer, assignment or  contribution by the Company of
          shares of Capital Stock (or any options, warrants or rights to
          acquire Capital Stock), or all or substantially all of the assets of,
          any Unrestricted Subsidiary of the Company to another Unrestricted
          Subsidiary of the Company."

          (d) The definitions of "Motorola  Agreements" and "Northern  Telecom
     Agreements" contained in Section 101 of the Indenture are hereby deleted,
     and the phrase "a Motorola Agreement or a Northern Telecom  Agreement"
     contained in clause (ii) of the definition of "Permitted  Lien" is hereby

     and replaced with the phrase "a Vendor Financing Agreement or any
     Lien (including Liens on Capital Stock of any Restricted Subsidiary) to
     the extent it secures Debt outstanding under a Credit Facility."

                              RECITALS OF THE COMPANY

         WHEREAS,  the Company  and the  Trustee  heretofore  executed  and
delivered  an  Indenture,  dated as of February 15, 1994, as heretofore amended

         WHEREAS, pursuant to the Indenture, the Company issued and the Trustee

         WHEREAS,  Section 902 of the Indenture provides that with the consent
of the Holders of not less than a majority in principal amount at Stated

Consents"), the Company, when authorized by a resolution of its Board of
Directors, and the Trustee may enter into an indenture or indentures

         WHEREAS, the Company has obtained the Requisite Amendment Consents to

         WHEREAS, the Company has delivered, or caused to be delivered, to the

         NOW, THEREFORE, the Company hereby covenants and agrees with the
Trustee for the equal and proportionate benefit of all Holders of the
Securities, as follows:

                                ARTICLE 1
               WAIVERS OF CERTAIN PROVISIONS OF INDENTURE

         Section 1.01. Waiver of Compliance with Certain Provisions of the
Indenture in Connection With the Clearnet Transfer. Subject to Section 3.01
hereof, compliance by the Company with Section 1009 of the Indenture
(including clause (iv) of the first paragraph thereof), to the extent that such
Section would apply to limit the ability of the Company to transfer  all of the
capital stock of Clearnet that is held directly by the Company on the date
hereof to McCaw  International,  Ltd. ("MIL"), a wholly owned Unrestricted
Subsidiary of the Company, or to any direct or indirect wholly owned subsidiary
of MIL that is  designated by MIL as the intended  recipient of such equity
interest in Clearnet,  is hereby  waived.  As a result of such waiver, any such
transfer shall not be deemed a Restricted Payment under Section 1009 of the
Indenture.

                                ARTICLE 2
              AMENDMENTS TO CERTAIN PROVISIONS OF INDENTURE

to Section 3.01 hereof, the Indenture is hereby amended in the following
respects:

          (a) The definition of "Credit Facility" contained in Section 101 of
     the Indenture is hereby amended to read in its entirety as follows:

                 "'Credit Facility' means any credit facility (whether a term
          or revolving type) of the type customarily entered into with banks,
          between the Company and/or any of its Restricted Subsidiaries, on the
          one hand, and any banks or other lenders, on the other hand (and any
          renewals, refundings, extensions or replacements of any such credit
          facility), which credit facility is designated by the Company as a
          "Credit Facility" for purposes of this Indenture, to the extent that
          the aggregate principal balance of Debt that is Incurred and
          outstanding under all Credit Facilities at any time does not exceed
          $1,905,000,000."

          (b) The definition of "Incur" contained in Section 101 of the
    Indenture is hereby amended to read in its entirety as follows:

                 "'Incur' means, with respect to any Debt or other obligation
          of any Person, to create, issue, incur (by conversion, exchange or

          required pursuant to generally accepted accounting principles or
          otherwise, of any such Debt or other obligation on the balance sheet
          of such Person (and "Incurrence", "Incurred", "Incurrable" and
          "Incurring" shall have meanings correlative to the foregoing);
          provided, however, that a change in generally accepted accounting
          principles that results in an obligation of such Person that exists
          at such time becoming Debt shall not be deemed an Incurrence of such
          Debt; provided further, however, that the accretion of original issue
          discount on Debt shall not be deemed to be an  Incurrence of Debt.
          Debt otherwise Incurred by a Person  before it becomes a Subsidiary
          of the Company shall be deemed to have been Incurred at the time it
          becomes such a Subsidiary."

          (c) The definition of "Investment" contained in Section 101 of
    the Indenture is hereby amended to read in its entirety as follows:

          otherwise), or purchase or acquisition of Capital Stock, bonds,
          notes, debentures or other securities or evidence of Debt issued by,
          any other Person; provided that a transaction will not be an
          Investment to the extent it involves (i) an Asset Disposition, (ii)
          the issuance or sale by the Company of its Capital Stock (other than
          Disqualified Stock), including options, warrants or other rights to
          acquire such Capital Stock (other than Disqualified Stock) or (iii)
          a transfer, assignment or contribution by the Company of shares of
          Capital Stock (or any options, warrants or rights to acquire Capital
          Stock), or all or substantially all of the assets of, any
          Unrestricted Subsidiary of the Company to another Unrestricted
          Subsidiary of the Company."

          (d) The definitions of "Motorola Agreements" and "Northern Telecom
    Agreements" contained in Section 101 of the Indenture are hereby deleted,
    and the phrase "a Motorola Agreement or a Northern Telecom Agreement"

          Financing Agreement; (ii) (A) any other Debt (including Guarantees

          by the Securities and the Senior Redeemable Discount Notes due 2003
          issued by NEXTEL Communications, Inc.), (B) any Debt (including
          Guarantees thereof) of OneComm Corporation and its Subsidiaries
          outstanding on July 28, 1995 (including the OneComm Notes), and (C)

          expenditure and working capital requirements; (iv) any Debt

          with the renewal, refunding or extension, provided that such renewal,

          the extent that it does not result in an increase in the aggregate
          principal amount (or, if such Debt provides for an amount less than
          the principal amount thereof to be due and payable upon a declaration
          of acceleration of the maturity thereof, in an amount not greater

          the Securities on subordination terms no less favorable to the

          be renewed, refunded or extended; provided, however, that in no event
          shall the aggregate amount of Debt that is Incurred and  outstanding
          under clauses (i), (iii) and (iv) at any time exceed $1,910,000,000;
          provided further, however, that no Debt that is represented by
          unsecured notes originally issued by the Company on or after June 1,
          1997 and ranking pari passu with the Securities ("New Notes") shall

          at such time becoming Debt shall not be deemed an Incurrence  of such
          Debt; provided further, however, that the  accretion of original
          issue discount on Debt shall not be deemed to be an Incurrence of

          Unrestricted Subsidiary, and may designate any newly-created
          Subsidiary as an Unrestricted Subsidiary, if at the time such
          Subsidiary is created it contains no assets (other than such de
          minimis amount of assets then required by law for the formation of
          corporations) and no Debt. Subsidiaries of the Company that are not

          Subsidiaries. The Board of Directors shall not change the designation
          of a Subsidiary of the Company more than twice in any period of five
          years."

          provided, however, that a change in generally accepted accounting
          principles that results in an obligation of such Person that exists
          at such time becoming Debt shall not be deemed an Incurrence of such
          Debt; provided further, however, that the accretion of original issue
          discount on Debt shall not be deemed to be an Incurrence of Debt.
          Debt otherwise  Incurred  by a Person  before it becomes a Subsidiary

          for an amount less than the  principal  amount  thereof to be due and
          payable upon a declaration of acceleration of the maturity  thereof,
          in an amount not greater than such lesser amount) of such Debt
          (except as permitted by clause (A) or (B) above), (b) to the extent
          such renewed, refunded or extended Debt does not require the payment
          of all or a portion  of the principal thereof (whether  pursuant  to
          repurchase, redemption, repayment, defeasance, retirement, sinking
          fund payment, payment at stated maturity or otherwise) prior to the
          final stated maturity of the Debt being renewed, refunded or extended
          and (c) if the Debt to be so renewed, refunded or extended is Debt of
          the Company that is subordinate  in right of payment to the 
          Securities, then the new Debt is subordinated in right of payment to
          the Securities on subordination terms no less favorable to the
          Holders of the Securities in their capacities as such than the
          subordination  terms (or other  arrangement)  applicable to the Debt
          to be renewed, refunded or extended;  provided,  however,  that in no
          event shall the  aggregate amount of Debt that is Incurred and
          outstanding  under clauses (i),  (iii) and (iv) at any time exceed
          $1,910,000,000; provided further, however, that no Debt that is
          represented by unsecured notes originally issued by the Company on or
          after June 1, 1997 and ranking pari passu with the Securities ("New
          Notes") shall be Incurred under  clause (iii)  above,  unless the
          amount of Debt represented  by the issue of New  Notes  could  have
          been Incurred, on or after June 1, 1997, pursuant to the provisions
          of Section 1008."

          Restricted Payment and the  Incurrence  of any Debt the net  proceeds
          of which  are used to  finance such Restricted  Payment,  then, in
          the case of any Restricted  Payment  described in clause (i), (ii) or
          (iii) above,  the  Consolidated  Debt to  Annualized  Operating Cash
          Flow Ratio  would  not have  exceeded  5.0 to 1 and,  in the case of
          any  Restricted  Payment described in clause (iv) above,  the Company

          it contains no assets (other than such de minimis amount
          of assets then required by law for the formation of
          corporations) and no Debt. Subsidiaries  of the Company that are not
          designated by the Board of Directors as Restricted or Unrestricted
          Subsidiaries shall be deemed to be Restricted Subsidiaries.
          Notwithstanding any provisions of this Section 1011, all
          Subsidiaries of a Restricted  Subsidiary  shall be Restricted
          Subsidiaries and all Subsidiaries of an Unrestricted Subsidiary shall

    the Indenture is hereby amended to read in its entirety as follows:

                 "'Credit Facility' means any credit facility (whether a term
          or revolving type) of the type customarily entered into with banks,
          between the Company and/or any of its Restricted Subsidiaries, on the
          one hand, and any  banks or other lenders, on the other hand (and any
          renewals, refundings, extensions or replacements of any such credit
          facility), which credit facility is designated by the Company as a
          "Credit  Facility" for purposes of this Indenture, to the extent that
          the aggregate  principal  balance of Debt that is Incurred and

          provided,  however,  that a change in generally accepted  accounting
          principles that results in an obligation of such Person that exists
          at such time becoming Debt shall not be deemed an Incurrence  of such
          Debt;  provided  further,  however, that the  accretion of original
          issue discount on Debt shall not be deemed to be an  Incurrence of
          Debt. Debt otherwise Incurred  by a Person  before it becomes a
          Subsidiary of the Company shall be deemed to have been Incurred at
          the time it becomes such a Subsidiary."

          the issuance or sale by the Company of its Capital Stock (other than
          Disqualified  Stock),  including  options,  warrants or other rights
          to acquire such Capital Stock (other than  Disqualified  Stock) or
