provided that, with the prior written consent of the Required Lenders, the
amount set forth above for any December 31 may be reduced (x) to the extent the
amount of Capital Expenditures by the Borrower and its Subsidiaries through
such December 31 are less than the maximum amount of Capital Expenditures
permitted through such December 31 by Section 7.08(c) of the Credit Agreement
and on the condition that the maximum amounts of Capital Expenditures permitted
by said Section are reduced by an equivalent amount or (y) to the extent the
operating performance of the Borrower or the expected operating performance of
the Borrower would indicate an excess amount in the Equity Contribution
Account.

                 The amounts set forth above shall be referred to in this
Agreement as the "Equity Holder Commitments" of the Parent Equity Holders.  The
Parent may from time to time, upon not less than 10 days' prior written notice,
require that the Parent Equity Holders make the New Equity Contributions
contemplated hereby in advance of any date specified above, and if any such
notice is given, the Parent Equity Holders shall so make such New Equity
Contributions on the date and in the amount so required in such notice.

                 (d)  Acceleration of New Equity Contributions.  If an Event of
Default shall have occurred and be continuing at any time hereafter, the Parent
shall be entitled, on demand, to accelerate the due date of any and/or all New
Equity Contributions thereafter to be made pursuant to Section 2(c) as shall be
necessary so that the aggregate amount of New Equity Contributions made after
the date hereof through and including the date of such demand shall be at least
equal to 65% of the aggregate outstanding principal amount of the Loans under
the Credit Agreement on the date of such demand.  Any such demand shall be made
by written notice to the Parent Equity Holders, whereupon such New Equity
Contributions shall be immediately due and payable, without further notice or
demand, all of which are hereby waived.  Such accelerated New Equity
Contributions shall be deemed applied to the obligations to make New Equity
Contributions provided in Section 2(c) in inverse order of the due date
thereof.

                 (e)  Obligations Not Released Upon Joinder of New Holders.  In
the event any New Holder joins in this Agreement as provided in Section 3, the
obligations of any other party hereto who is then a Parent Equity Holder to
make New Equity Contributions under this

<PAGE>   5
                                     - 5 -

Section 2 shall not by virtue thereof be released, reduced, discharged or
otherwise affected.  If and to the extent that on any date a New Holder
actually makes any New Equity Contributions to be made by it as provided in the
Joinder Agreement pursuant to which it becomes a Parent Equity Holder, such New
Equity Contributions so made shall be deemed to have satisfied, in an
equivalent amount, the requirements for New Equity Contributions to be made by
the other Parent Equity Holders, with such amount being applied among such
Persons pro rata in accordance with their respective Equity Holder Commitments,
or otherwise in such manner as may be provided in such Joinder Agreement.

                 (f)  Borrower Equity Contributions.  To the extent that, under
Section 4.03 of the Undertaking and Security Agreement, any amounts held in the
Equity Contribution Account are remitted to or upon the order of the Borrower,
the amount so remitted shall constitute an Equity Contribution by the Parent in
the Borrower.

                 SECTION 3.  Issuance and Transfer of Capital Stock; Joinder of
New Holders.

                 (a)  Issuance of Capital Stock.  Neither the Parent nor the

Capital Stock, except as follows:

                 (i)  either the Parent or the Borrower may issue shares or
         quotas, respectively, of its Capital Stock to any Person who is at
         such time already a Parent Equity Holder or Borrower Equity Holder, as
         the case may be; and

                 (ii)  if after giving effect thereto no Change of Control
         would occur, either the Parent or the Borrower may issue shares or
         quotas, respectively, of its Capital Stock to any other Person (a "New
         Holder"), provided that (A) if such New Holder is to become a Parent
         Equity Holder, such New Holder executes and delivers to the Parent and
         the Administrative Agent a Joinder Agreement (a "Joinder Agreement")
         substantially in the form of Annex A hereto, pursuant to which, among
         other things, such New Holder becomes a Parent Equity Holder hereunder
         and undertakes to make New Equity Contributions hereunder as specified
         in such Joinder Agreement, (B) if such New Holder is to become a
         Borrower Equity Holder, such New Holder executes and delivers to the
         Administrative Agent a pledge agreement or other security document or
         documents, in form and substance satisfactory to the Administrative
         Agent, providing for the pledge of the shares or quotas, as the case
         may be, of Capital Stock to be acquired by such New Holder to the
         Administrative Agent, for the benefit of the Lenders, and (C) such New
         Holder contemporaneously therewith also so delivers to the Parent, the
         Borrower and the Administrative Agent (x) evidence as to the corporate
         or other organizational existence of such New Holder, (y) evidence as
         to the due authorization, execution, legality, validity,

<PAGE>   6
                                     - 6 -

         binding effect and enforceability of the documents referred to above,
         and compliance with any applicable laws or other governmental
         requirements (including any required governmental approvals, filings
         or other requirements) in connection therewith, and (z) a favorable
         legal opinion of counsel, reasonably satisfactory to the
         Administrative Agent, covering such matters and such other matters as
         may be reasonably requested by the Borrower or the Parent, as
         applicable, and/or the Administrative Agent.

                 (b)  Transfers of Capital Stock.  No Equity Holder shall,
directly or indirectly (by merger, consolidation, amalgamation or otherwise),
sell, assign, transfer or otherwise dispose of all or any portion of the
Capital Stock of the Parent or the Borrower, as applicable, owned by it, except
as follows:

                 (i)  a Parent Equity Holder may transfer shares of Capital
         Stock of the Parent owned by it to any other Person who is at such
         time already a Parent Equity Holder;

                 (ii)  a Borrower Equity Holder may transfer quotas of Capital
         Stock of the Borrower owned by it to any other Person who is at such

                 (iii)  an Equity Holder may merge, consolidate or amalgamate
         with, or sell, transfer or otherwise dispose of all or substantially
         all of its properties and assets as an entirety (including the Capital
         Stock of the Parent or the Borrower, as the case may be, owned by it)
         to, any Person, provided that (A) no Change of Control would result
         therefrom, and (B) the surviving or resulting Person (if other than
         such Equity Holder) or acquiring Person expressly assumes the
         obligations of such Equity Holder under this Agreement and each other
         Loan Document to which it is a party pursuant to an assumption
         agreement satisfactory in form and substance to the Administrative
         Agent; and

                 (iv)  if after giving effect thereto no Change of Control
         would occur, an Equity Holder may transfer shares or quotas of the
         Capital Stock of the Parent or the Borrower, as applicable, owned by
         it to any New Holder who delivers documents and otherwise complies
         with the requirements specified in Section 3(a)(ii) which are
         applicable in the case of issuance of Capital Stock to a New Holder.

                 SECTION 4.  Representations and Warranties.  Each Equity
Holder represents and warrants to the Borrower as follows:

Enforceability.  It has all necessary corporate power and authority to execute,
deliver and perform its obligations under this Agreement; the execution,
delivery and performance by it of this Agreement has been duly authorized by
all necessary corporate action on its part; and this Agreement has been duly

binding obligation, enforceable in accordance with its terms (except as the
enforceability thereof may be limited by (a) applicable bankruptcy, insolvency,
moratorium or other similar laws affecting the enforcement of creditor's rights
generally and (b) the application of general principles of equity (regardless
of whether such enforceability is considered in a proceeding at law or in
equity)).

                 (c)  No Breach.  Except for consents and approvals already
received, none of the execution and delivery of this Agreement, the
consummation of the transactions herein contemplated and compliance with the
terms and provisions hereof will conflict with or result in a breach of, or
require any consent under, (a) its charter, by-laws and other constitutive
documents, (b) any applicable rule or approval of a Governmental Authority, (c)
any material order, writ, injunction or decree of any Governmental Authority,

such Equity Holder is not in violation of any such rule, approval, order, writ,
injunction or decree or such charter, by-laws or other constitutive documents,
except such violations of rules and governmental approvals that could not
reasonably be expected to have a Material Adverse Effect.

                 (d)  Governmental Approvals.  No consent, approval or
authorization of, or registration, filing, or declaration with, any
Governmental Authority is required in connection with the execution, delivery
or performance by it of this Agreement.  It is not necessary to ensure the
legality, validity, enforceability or admissibility into evidence of this
Agreement in Argentina, the Cayman Islands or the jurisdiction of organization

Governmental Authority in Argentina, the Cayman Islands or such other
jurisdiction or that any such agreement or document be stamped with any stamp,
registration or similar transaction tax; provided, however, that a nominal
Cayman Islands stamp duty will be payable if this Agreement is brought to or

reduction or any other legal or equitable defense which such Equity Holder has
or hereafter may have, against any other person (including that Administrative
Agent or any of the Lenders) for any reason whatsoever (including, without

obligations under the Credit Agreement, in bankruptcy or otherwise).

Facility, and (iv) Lender shall have no obligation to make any requested Advance
if, after giving effect thereto and any Advances made under the other Borrowing
Affiliate Notes, the aggregate amount of all Advances made by the Lender would
exceed its Available Commitment. The aggregate obligation of the Lender to make
Advances to the Borrowing Affiliate under this Note is called its "Commitment."

            (b) Subject to and upon the terms and conditions of this Agreement,
the Borrowing Affiliate may, at its option, avail itself of the Commitment in
one or more drawdowns in the amount of the relevant Invoice (in the case of
Invoice Advances) or the relevant Refinancing Advance, but in any event not in
excess of the remaining aggregate amount of the Commitment and in all cases
subject to the limitations in Sections 2.1(a) and 2.2(a).

SECTION 2.2.  PROCEDURE FOR BORROWING; ADVANCES.

            (a) The Borrowing Affiliate shall deliver to the Lender at the
address listed in the first sentence hereof, at least five (5) Business Days
prior to each proposed financing hereunder, (i) a Request for Financing, for
each Advance which shall specify (A) the date of the financing, (B) the
principal amount to be financed, and (C) the recipient of such Advance, which
shall be either the Vendor or MCC. Upon receipt of such documentation and
subject to the limitations set forth herein (including, without limitation,
subsection 2.1(a) hereof), the Lender shall advance to the Borrowing Affiliate
(or otherwise as directed by the Borrowing Affiliate pursuant hereto) a
principal amount which shall equal the least of (x) the amount requested as an
Advance pursuant to such Request for Financing, (y) the amount paid or due and
payable as reflected in the Invoice submitted in connection with such Request
for Financing, exclusive of import taxes and/or other duties, or (z) the
remaining Attributable Borrowing Sublimit. Any Request for Financing, once
delivered to the Lender, shall be irrevocable and shall commit the Borrowing
Affiliate to receive the amount to be advanced by the Borrowing Affiliate
pursuant to the immediately preceding sentence on the date specified therein.

            (b) Not later than 2:30 p.m., Chicago time, on the date specified in
the Request for Financing, but subject to the terms and conditions hereof and to
the fulfillment of all applicable conditions set forth in subsection 2.2(a) and
Section 4 hereof, the Lender shall pay the amount described in the second
sentence of subsection 2.2(a) hereof, directly to Vendor (in the case of Invoice
Advances) or MCC (in the case of Refinancing Advances) at the account specified
in the Request for Financing. The Borrowing Affiliate authorizes and directs the
Lender to, without any further action or instruction to disburse the proceeds of
such Advance directly to the Vendor or MCC, as applicable, as specified in the
Request for Financing. The Borrowing Affiliate

<PAGE>   4

acknowledges that disbursement of funds to a Person other than the Borrowing
Affiliate in accordance with the Request for Financing pursuant to the
immediately preceding sentence shall be deemed receipt by the Borrowing
Affiliate of the proceeds of the Advances made hereunder.

SECTION 2.3.  REPAYMENT OF PRINCIPAL OF ADVANCES.

            (a) The Borrowing Affiliate shall pay to the Lender the principal of
the Advances made by the Lender outstanding at the close of business on the
Commitment Termination Date in eight (8) consecutive semi-annual installments on
the Payment Dates (provided that the last such payment shall be in an amount
sufficient to repay in full the principal amount of such Advances), with the
amount of the installment paid on each Payment Date to be equal to the
respective percentages of the principal of such Advances outstanding at the
close of business on the Commitment Termination Date as set forth below:

            (b) The Advances shall be repaid as and when necessary to cause the
aggregate principal amount of the Advances outstanding not to exceed the
Attributable Borrowing Sublimit and as required by subsection 2.4(a) hereof.

SECTION 2.4.  PREPAYMENTS.

            (a) Mandatory Prepayment.

            Not later than the date 90 days after the end of each fiscal year of
the Borrowing Affiliate (commencing with the fiscal year ending on December 31,
2000), the Borrowing Affiliate shall prepay Advances in an aggregate amount
equal to 50% of the Borrowing Affiliate's Excess Cash Flow (determined on a
consolidated basis) for such fiscal year, if positive.

            (b) Optional Prepayment.
<PAGE>   5

            The Borrowing Affiliate may prepay Advances, in whole or in part, in
integral multiples of $100,000 upon not less than five (5) days prior written
notice to the Lender of the principal amount to be prepaid and the date of such
prepayment; provided that the Borrowing Affiliate and the Lender agree that any
Advances so prepaid shall be immediately applied to the outstanding advances of
the Lender payable under the Master Agreement, unless deposited by the Lender
into the Prepayment Escrow Deposit Account to the extent permitted by and in
accordance with Section 2.5(a)(ii) of the Master Agreement; and provided further
that no prepayment of any Advances shall be made by the Borrowing Affiliate
after the occurrence and during the continuance of a Default or an Event of
Default under the Master Agreement without the prior written consent of MCC. On
the date specified for prepayment, the Borrowing Affiliate shall pay such
principal amount plus accrued interest on such principal amount prepaid to the
date of such prepayment.

            (c) Effect of Prepayment.

            All Advances prepaid, whether by mandatory or optional prepayment,
may not be reborrowed other than pursuant to a Rollover Loan to the extent
permitted by and in accordance with Section 2.5(a)(ii) of the Master Agreement
and the Commitment shall automatically be reduced by the amount of such
prepayment. Such prepayments shall be applied pro rata to reduce each subsequent
principal payment due under Section 2.3.

            (d) Certain Reimbursements In Respect of Prepayments.

            Without affecting the obligations of the Borrowing Affiliate set
forth above in subsection 2.4(a), in the event that the Borrowing Affiliate is
prohibited by applicable law from obtaining the funds necessary to make the
prepayment or requires the approval of a Governmental Authority in order to do
so (which has not theretofore been obtained) and therefore is unable to make the
prepayment within the period specified above (notwithstanding the reasonable
efforts of the Borrowing Affiliate), the Borrowing Affiliate shall establish a
restricted escrow account, established for the benefit of MCC (which pursuant
hereto and pursuant to the Master Agreement is a third party beneficiary and
collateral assignee of this Note), into which such funds shall be deposited and
the period for making such prepayment shall be extended by up to 270 days (i.e.,
a total of 360 days from the end the relevant fiscal year) with such funds
released to MCC from escrow on the earlier of the end of such extended
prepayment period and the date the necessary consents and/or waivers are
obtained. At the sole discretion of the Lender and with the consent of MCC and
in lieu of the escrow account referred to in the preceding sentence, the Lender
may require, if the Borrowing Affiliate is unable to make the prepayment
required above due to the circumstances described in the immediately preceding
sentence, the Borrowing Affiliate to make such prepayment to the Lender in the
local currency of the Borrowing Affiliate in an amount equal, at the then
prevailing spot rates (as determined by the Lender and MCC) for conversion of
such currency into Dollars, to the required prepayment amount in Dollars.

SECTION 2.5.  INTEREST; FEES.

            (a) Except as otherwise consented to by MCC, the Borrowing Affiliate
shall pay to

<PAGE>   6

the Lender interest on the outstanding principal amount of each Advance made by
the Lender, for the period commencing on the date of such Advance until such
Advance is paid in full, at the a rate per annum equal to the rate payable by
the Lender to MCC with respect to each corresponding Advance to the Lender
constituting an Attributable Borrowing for the Borrowing Affiliate under the
Master Agreement. Interest shall be computed as provided in the Master
Agreement.

            Accrued interest on each Advance shall be paid in arrears on the
Interest Payment Dates. Notwithstanding the foregoing, Interest that is payable
at the Post-Default Rate shall be payable from time to time on demand of the
Lender; provided that the Lender is then paying interest on Advances at the
Post-Default Rate and MCC has demanded such amount from Lender. All payments of
interest under this Note made to the Lender by the Borrowing Affiliate shall be
immediately applied to Lender's obligation under the Master Agreement.

            Without prejudice to the provisions of Section 6.2 hereof, in the
event of default by the Borrowing Affiliate in payment of any principal amount
of the Advances or interest thereon when due (whether at the stated maturity, by
acceleration or otherwise), the Borrowing Affiliate shall pay to the Lender
interest on such past due and unpaid principal amount and (to the extent
permitted by applicable law) on such defaulted interest from the due date until
the date of payment in full (both before as well as after judgment), at the
Post-Default Rate. In addition, the Borrowing Affiliate shall indemnify the
Lender against any actual loss or expense which it may sustain or incur as a
direct consequence of the default by the Borrowing Affiliate in payment of any
principal amount of the Advances or interest thereon. Each determination of any
loss or expense by the Lender under this paragraph (b) shall be conclusive in
the absence of manifest error.

SECTION 2.6.  PAYMENTS.

            Except as otherwise provided herein, all payments whatsoever by the
Borrowing Affiliate to the Lender hereunder shall be made in Dollars in same-day
funds to the order of the Lender at New York, U.S.A., ABA# 021000021, for the
account of Motorola/Nextel, Account # E12713A (or such other place as the Lender
shall have designated in writing to the Borrowing Affiliate at least five (5)
Business Days prior to the scheduled payment date), not later than 1:00 p.m.
Chicago time, on the day on which such payment shall become due. Any amounts
received after such time on any date may, in the discretion of the Lender, be
deemed to have been received on the next succeeding Business Day for purposes of
calculating interest thereon.

            If any payment hereunder would otherwise be due on a day that is not
a Business Day, such payment shall be made on the next succeeding day that is a
Business Day and including the additional days elapsed in the computation of the
interest payable on such next succeeding Business Day.

SECTION 2.7.  USE OF PROCEEDS.

            The Borrowing Affiliate agrees that the proceeds of the Advances
will be used by the Borrowing Affiliate to finance the purchase of iDen
Equipment and Services acquired pursuant

<PAGE>   7

to the iDEN Equipment and Service Agreements (including, without limitation,
down payments, milestone payments and other payments due under the iDEN
Equipment and Service Agreements) to be used in connection with the System of
the Borrowing Affiliate and related transportation and shipping costs but
excluding import taxes and/or duties related thereto; it being understood that
the proceeds of the Refinancing Advances may be used to repay Indebtedness owing
under the 1997 Infocom Facility and the Infocom Bridge Facility. The proceeds of
each Advance shall be paid, subject to the last sentence of Section 2.2(b), by
the Lender directly to either (a) Motorola Credit Corporation if such Advance is
a Refinancing Advance, or (b) the Vendor in the case of an Invoice Advance.

                    SECTION 3. REPRESENTATIONS AND WARRANTIES

            The Borrowing Affiliate hereby acknowledges that under the terms of

Affiliate Security Deposit Agreement") and execution and delivery of all related

                              SECTION 5. COVENANTS

            So long as this Note shall remain outstanding or any Obligations or
obligations of the Lender under the Master Agreement shall remain unpaid, the
