      SECTION 2.01 Purchase and Sale. Upon the terms and subject to the
conditions of this Agreement, Seller agrees to issue and sell to each Buyer and
each Buyer irrevocably agrees in its own name severally and not jointly, to
purchase from Seller the Securities set forth opposite such Buyer's name on
Schedule A hereto at the Closing. In the event that any DLJ Entity fails to

Schedule A hereto at the Closing, DLJMB agrees to purchase such Securities at
the Closing. The aggregate purchase price for the Securities (the "Purchase
Price") payable by each Buyer is the amount in cash or in assets specified
opposite such Buyer's name on Schedule A hereto. The Purchase Price shall be
paid as provided in Section 2.02.

      SECTION 2.02 Closing. The closing (the "Closing") of the purchase and sale
of the Securities hereunder shall take place at the offices of Mayer, Brown &
Platt, 1675 Broadway, New York, NY 10019, as soon as possible, but in no event
later than five business days, after

                                       4
<PAGE>

satisfaction of the conditions set forth in Article 5, or at such other time or
place as Buyers and Seller may agree. At the Closing:

      (a) Each Cash Investor shall deliver to Seller, in immediately available
funds, one-third (1/3) of the Purchase Price (the "Initial Cash Contribution")
set forth opposite such Buyer's name on Schedule A hereto, by wire transfer (or
other means acceptable to Seller) to the account of Seller described on Schedule
B.

      (b) NWIP will (i) execute and deliver to the Custodian one or more stock
certificates, together with stock powers duly executed in blank, representing
all the outstanding stock of Expansion Co., together with irrevocable
instructions to release the stock of Expansion Co. to Seller upon receipt of a
written notice from Seller and NWIP that FCC approval of the License Transfer

transfer of the stock of Expansion Co. to Seller will occur immediately upon
receipt by the Custodian of the notice referred to above.

      (c) Motorola will execute and deliver to the Company Supplement No.1 to
the Infrastructure Equipment Purchase Agreement by and between Opco and
Motorola, in substantially the form of Exhibit A.

      (d) Seller shall deliver to each Buyer certificates, or other appropriate
documentation, for the relevant Securities duly registered in the name of such
Buyer.

      SECTION 2.03 Subsequent Payments. (a) Each Cash Investor shall deliver
additional payments of one-third (1/3) of such Cash Investor's Purchase Price
(each, a "Subsequent Cash Contribution") to Seller in immediately available
funds, by wire transfer (or other means acceptable to Seller) to the account
described on Schedule B (or such other account as the Seller may from time to
time designate) on each of September 9, 2000 and September 9, 2001 (each, a
"Subsequent Payment Date").

      (b) Seller has the right to (i) accelerate payment of each of the
Subsequent Cash Contributions by up to 60 days prior to the relevant Subsequent
Payment Date by providing the relevant Buyers with notice at least 30 days
before the proposed payment date and (ii) assign the right to receive any unpaid
Subsequent Cash Contribution to a lender as security for an interim advance to
the Company by such lender.

      (c) Each Cash Investor acknowledges and agrees that, if the Closing
occurs, its obligation to make payments to Seller of the relevant Subsequent
Cash Contributions constitutes an absolute, irrevocable and unconditional
obligation, and shall not be subject to claim, set-off, or other rights which
such Buyer may have at any time against the Seller. If a Buyer fails to pay a
Subsequent Cash Contribution to the Seller more than two business days after the
Subsequent Payment Date: (i) such defaulting party will be subject to liquidated
damages in the amount of

                                       5
<PAGE>

25% of its Company Capital Stock (including all of the Company Capital Stock
acquired under the Original Subscription Agreement) (which liquidated damages,
in the case of the DLJ Entities, shall be paid to DLJMB (in lieu of the
Company), if DLJMB timely paid (or caused to be paid timely) the Subsequent Cash
Contribution), (ii) all remaining Subsequent Cash Contributions of such
defaulting party shall become immediately due and payable in full, (iii) the
outstanding amount shall accrue interest at a rate per annum equal to 200 basis
points over the highest rate of interest charged from time to time by the
Seller's senior lenders, (iv) the rights of such defaulting party under the
Shareholders' Agreement but none of its obligations will terminate and (v) the
Series A Preferred of such defaulting party (including all of the Series A
Preferred acquired under the Original Subscription Agreement) will convert to
Class A Common Stock and, in the case of NWIP, the Series C Preferred (including
all of the Series C Preferred acquired under the Original Subscription
Agreement) will convert to Class B Common Stock, in each case in accordance with
the Restated Certificate.

      (d) (i) Without limiting Section 2.03(c), in the event that any DLJ Entity
fails to make any Subsequent Cash Contribution on the applicable Subsequent
Payment Date, DLJMB shall make (or shall cause to be made) such Subsequent Cash
Contribution within two business days of such Subsequent Payment Date. DLJMB
acknowledges and agrees that, if the Closing occurs, its obligation to make
payments to Seller of Subsequent Cash Contributions of other DLJ Entities
pursuant to the preceding sentence constitutes an absolute, irrevocable and
unconditional obligation, and shall not be subject to claim, set-off, or other
rights which DLJMB may have at any time against the Seller nor shall the Seller
be required to exhaust any remedies against the defaulting party before
proceeding against DLJMB to enforce this Section 2.03(d) against DLJMB. In the
event of a payment default by DLJMB under this paragraph (d), (i) all remaining
Subsequent Cash Contributions of DLJMB shall become immediately due and payable
in full, (ii) the outstanding amount shall accrue interest at a rate per annum
equal to 200 basis points over the highest rate of interest charged from time to
time by the Seller's senior lenders, (iii) the Series A Preferred of DLJMB
(including all of the Series A Preferred acquired under the Original
Subscription Agreement) will convert to Class A Common Stock in accordance with
the Restated Certificate and (iv) the rights of DLJMB but none of its
obligations under the Shareholders' Agreement will terminate.

            (ii) Without limiting Section 2.03(c), in the event that NWIP fails
to make any Subsequent Cash Contribution on the applicable Subsequent Payment
Date, Seller shall have the right, until all remaining Subsequent Cash
Contributions of NWIP are made in accordance with the terms hereof, to set-off
the full amount of all remaining Subsequent Cash Contributions of NWIP against
any and all amounts which Seller, Opco or any subsidiary thereof owes to NWIP
under the Collateral Agreements (as such term is defined in the Joint Venture
Agreement), regardless of whether any such amounts owed to NWIP arose prior to
or following NWIP's failure to make a Subsequent Cash Contribution hereunder.

                                       6
<PAGE>

      (e) In the event that a Cash Investor transfers all or part of its
Securities in advance of completing its payment obligations under Article 2,
such Cash Investor shall remain primarily liable for the transferee's remaining
Subsequent Cash Payments.

      (f) NWIP covenants and agrees that it will cause the representations and
warranties in Section 4.12 to remain true and correct at all times from the date
hereof until the License Transfer has been consummated and shall also use its
commercially reasonable best efforts to cause the representations and warranties
set forth in Section 4.11 to remain true and correct at all times from the date
hereof until the License Transfer has been consummated. NWIP agrees that, upon
such approval of the FCC as will permit the License Transfer to be lawfully
consummated, such transfer will thereupon be deemed to be accomplished without
any further action on the part of NWIP, and the Company and the Custodian are
hereby irrevocably authorized at such time to deliver the stock certificates and
completed stock power in such manner as necessary and appropriate to consummate
(i) the License Transfer and (ii) the pledge of the stock of Expansion Co. to
Opco's senior lenders as contemplated by the terms of the Credit Facility.

      SECTION 2.04 Remedies. Each Buyer acknowledges that the Seller is a
start-up company and agrees that as such the Seller would suffer irreparable
harm, including great harm to its ability to operate in accordance with its
business plan during its critical start-up phase, in the event that such Buyer
failed to pay in full, as and when due, its portion of the Purchase Price. The
parties agree that if any provision of this Article 2 is not performed by a
Buyer in accordance with its specific terms or is otherwise breached,
irreparable damage to the Seller would occur, no adequate remedy at law would
exist and damages would be difficult to determine, and that the Seller will
therefore be entitled to (i) specific performance of the terms of this Article
2, (ii) the remedies set forth in Sections 2.03(c) and 2.03(d), including,
liquidated damages in the amount of 25% of such Buyer's Securities (which
damages are intended by the parties to compensate the Seller for the harm
suffered by reason of such Buyer's failure to pay when due its portion of the
Purchase Price, it being understood and agreed that recovery of damages in an
amount equal to such portion of the Purchase Price plus accrued interest thereon
shall not be sufficient to adequately compensate the Seller for such harm) and
(iii) any other remedy available under this Agreement or otherwise at law or in
equity.

                                   ARTICLE 3

                    REPRESENTATIONS AND WARRANTIES OF SELLER

Co.) is entitled under any provision of any agreement or other instrument
binding upon such Buyer (or, in the case of NWIP, NWIP or Expansion Co.) or any
of its assets or properties, to the extent that any of the foregoing would have
a material adverse effect on such Buyer or would prevent or otherwise render
such Buyer unable to perform its obligations under this Agreement or any other

imposition of any material Lien on any property or asset of such Buyer (or, in

      SECTION 4.06 Private Placement. (a) Such Buyer understands that (i) the
offering and sale of the Securities hereby is intended to be exempt from
registration under the 1933 Act and (ii) there is only a limited market for the
Securities, and there can be no assurance that any Buyer will be able to sell or
dispose of the Securities to be purchased by such Buyer.

      (b) Such Buyer's financial situation is such that such Buyer can afford to
bear the economic risk of holding the relevant Securities acquired hereunder for

loss of the investment in such Securities.

                                       11
<PAGE>

      (c) Such Buyer's knowledge and experience in financial and business
matters are such that it is capable of evaluating the merits and risks of the
investment in the relevant Securities, or such Buyer has been advised by a
representative possessing such knowledge and experience.

      (d) Such Buyer understands that the Securities acquired hereunder are a
speculative investment which involves a high degree of risk of loss of the
entire investment therein, that there are substantial restrictions on the
transferability of the Securities as set forth in the Shareholders' Agreement,
and that for an indefinite period following the date hereof there will be no (or
only a limited) public market for the Securities and that, accordingly, it may
not be possible for such Buyer to sell the Securities in case of emergency or
otherwise.

      (e) Such Buyer and its representatives, including, to the extent it deems
appropriate, its professional, financial, tax and other advisors, have reviewed
all documents provided to them in connection with the investment in the
Securities, and such Buyer understands and is aware of the risks related to such
investment.

      (f) Such Buyer and its representatives have been given the opportunity to
examine all documents and to ask questions of, and to receive answers from,
Seller and its representatives and Nextel and its representatives concerning the
terms and conditions of the acquisition of the Securities and related matters
and to obtain all additional information which such Buyer or its representatives
deem necessary.

      (g) All written information which such Buyer has provided to Seller and
its representatives and Nextel and its representatives concerning such Buyer and
such Buyer's financial position was true, complete and correct at the time it
was provided.

Regulation D under the 1933 Act.

      (i) Such Buyer is not relying on and acknowledges that no representation
is being made by any other Buyer, or any of its officers, employees, Affiliates,
agents or representatives, the Seller or any of its officers, employees,
Affiliates, agents or representatives, Nextel or any of its officers, employees,
Affiliates, agents or representatives, or any Management Stockholder, except for
representations and warranties expressly set forth in this Agreement and the

      SECTION 4.07 Litigation. There is no action, suit, investigation or
proceeding pending against, or to the knowledge of such Buyer threatened against
or affecting, such Buyer before any court or arbitrator or any governmental

adverse effect on its ability to consummate the transactions contemplated by
this Agreement or the other Transaction Documents.

      SECTION 4.08 Brokers or Finders' Fees. There is no investment banker,
broker, finder or other intermediary which has been retained by, will be

      SECTION 4.09 Capital of DLJMB. DLJ Merchant Banking II, Inc. ("DLJMB II,
Inc.") is an indirect wholly-owned subsidiary of Donaldson Lufkin & Jenrette,
Inc. ("DLJ") and is the managing general partner of DLJMB and certain affiliated
investment vehicles that coinvest with DLJMB. DLJMB and the other DLJ Entities
were organized with committed capital of $3 billion, of which approximately 25%
remains available for investment. The scheduled term of DLJMB extends through
2005 and no event or circumstance has occurred that would reasonably be expected
to cause the term of DLJMB to expire or be subject to termination prior to the
last Subsequent Payment Date. Through DLJMB and the other DLJ Entities, DLJMB
II, Inc. has access to freely available cash in an amount sufficient to make in
full and in a timely manner all committed investments contemplated to be made by
it (including its transferees, if any) hereunder, including the Subsequent Cash
Contributions, in the aggregate amount of $7,951,499. As of the date hereof,
each of the DLJ Entities is an Affiliate of DLJ.

      SECTION 4.10 Capital Commitment. Each Cash Investor has, and will have on

Contribution, as the case may be, in accordance with the terms of Article 2.

      SECTION 4.11 FCC Compliance; NWIP FCC Licenses. (a) Expansion Co. is the
holder of the NWIP FCC Licenses. Except as disclosed in Schedule 4.11, each of
the NWIP FCC Licenses is valid and in full force and effect. Except as disclosed
in Schedule 4.11, there are no conditions on the NWIP FCC Licenses that would
likely have a material adverse effect on such licenses or their use in an ESMR
network in the Territories as contemplated by the Joint Venture Agreement other
than those as set forth on the face of the NWIP FCC Licenses or in statutes and
FCC rules and policies of general applicability to the commercial mobile radio
industry. Except as disclosed in Schedule 4.11, there is no complaint,
investigation, notice of violation, or other proceeding against, or otherwise
relating to, the NWIP FCC Licenses, Expansion Co. or any member of the Nextel
Controlled Group pending or, to the knowledge of Expansion Co. or any member of
the Nextel Controlled Group, threatened by or before the FCC (i) that would
likely have a material adverse effect on the NWIP FCC Licenses or their use in
an ESMR network in the Territories as contemplated by the Joint Venture
Agreement, (ii) which questions or contests the validity of, or assignment to
the Company or any member of the Nextel Controlled Group, or seeks the
revocation, non-renewal or suspension of, any of the NWIP FCC Licenses, (iii)
which seeks the imposition of any modification or amendment with respect to any
of the NWIP FCC Licenses, or (iv) which could reasonably be expected to
adversely affect the ability of Seller to build and operate an iDEN system after
the Closing Date substantially as contemplated by the

                                       13
<PAGE>

relevant Transaction Documents other than proceedings which generally affect the
commercial mobile radio industry. Except as disclosed in Schedule 4.11,
Expansion Co. and the Nextel Controlled Group are in compliance in all material
respects with the FCC Law, and the rules and regulations of the FCC, including
without limitation all applicable eligibility criteria for holding the NWIP FCC
Licenses, except to the extent that noncompliance would not likely have a
material adverse effect on the NWIP FCC Licenses or their use in an ESMR Network
in the Territories as contemplated by the Joint Venture Agreement.

            (b) NWIP reaffirms the representations and warranties set forth in
Section 4.11(a) as of the date of the License Transfer, provided, that the
Seller acknowledges that NWIP is not responsible for a breach of such
representations and warranties under Section 4.11(a) resulting from any action
or inaction by the Seller or any of its subsidiaries with respect to such NWIP
FCC Licenses.

            (c) NWIP has waived the requirement set forth in Section 6.2B of the
Joint Venture Agreement that, prior to the expansion of the Territory to include
some or all of the non-Special Option Sections, the Company shall have completed
the Build Out of all Year One Build Areas in the Initial Sections before the end
of the Election Period (as such terms are defined in the Joint Venture
Agreement).

      SECTION 4.12 Newly Formed Corporation. Expansion Co. was incorporated on
August 11, 1999 in the State of Delaware solely for the purpose of effectuating
the transactions contemplated in this Agreement and the other Transaction
Documents and has not conducted any business or entered into any agreements or
commitments except with respect to the foregoing and has no obligations or
liabilities other than (i) those arising under, or contemplated by, the

common stock, no par value. The outstanding capital stock of Expansion Co. is
100 shares of common stock, all of which shares have been duly and validly
authorized, and are fully paid and nonassessable. NWIP owns all the outstanding
capital stock of Expansion Co. free and clear of any liens, and Expansion Co.
has no subsidiaries. Except as set forth in this Section 4.12, there are no
outstanding (i) shares of capital stock or voting securities of Expansion Co.,
(ii) securities of Expansion Co. convertible into or exchangeable for shares of
capital stock or voting securities of Expansion Co., (iii) options or other
rights to acquire from Expansion Co., or other obligation of Expansion Co. to
issue, any capital stock, voting securities or securities convertible into or
exchangeable for capital stock or voting securities of Expansion Co., or (iv)
obligation of Expansion Co. to repurchase or otherwise acquire or retire any
shares of capital stock or any convertible securities, rights or options of the
type described in (i), (ii), or (iii). Expansion Co. (x) has obtained such
proper authorization as may be required from its Board of Directors and its
shareholders of all corporate action taken by Expansion Co., (y) keeps its
assets and liabilities

                                       14
<PAGE>

separate from those of other entities (including Nextel and the Affiliates
thereof) and (z) does not hold itself out as being liable for the debts of
Nextel or any Affiliate thereof.

                                                                   SCHEDULE 4.11

                             SCHEDULE OF EXCEPTIONS

      Pursuant to Section 4.1 of the Agreement, the following sets forth certain
disclosures and other exceptions to the representations made at Section 4.1 of
the Agreement regarding the validity of the FCC Licenses. This schedule is
divided into two parts: Part I addresses issues that may affect multiple
licenses among the FCC Licenses, while Part II addresses issues that affect only
individual licenses among the FCC Licenses.

                   Part I: Issues Affecting Multiple Licenses

      1. Different Types of Licenses Carry Different FCC Obligations: The
licensee rights and obligations applicable to the FCC Licenses are not uniform
but rather depend upon the conditions under which each license was granted. The
FCC Licenses generally fall into three categories as follows:

      a. EA Licenses: Some of the FCC Licenses are authorizations, or
geographically "partitioned" portions of authorizations, that were issued to
Nextel as a result of an FCC spectrum auction.

      b. Wide Area Licenses: Other licenses among the FCC Licenses were granted
at specific sites, as opposed to Economic Areas. These licenses authorized
Nextel to build out the related channels in analog or digital mode and were
granted five-year waivers of the traditional one-year construction deadline
applicable to site-specific licenses. These site-specific, five-year,
analog/digital authorizations are known as Nextel's "wide-area" licenses. On May
20, 1997 the FCC issued an order (DA 97-1059) finding that the wide-area
licenses of Nextel and other parties qualified for "rejustification" of their
extended construction periods but also shortened the length of the construction
periods from five years to two with a final deadline of May 20, 1999 or the
earlier expiration date of the license, whichever comes first. On April 15,
1999, the FCC announced through a Public Notice (DA 99-698) that the FCC was
temporarily suspending the May 20, 1999 construction deadline for wide-area
licensees due to a decision by the U.S. Court of Appeals for the District of
Columbia in Fresno Mobile Radio v. FCC, 165 F.3d 965 (D.C. Cir., Feb 5, 1999).
On May 21, 1999, the FCC solicited comments on the construction requirements for
800 MHz wide area licensees (Public Notice, DA 99-974). The FCC has not released
a decision in this proceeding.
<PAGE>

      c. Analog Licenses: Another group of licenses reflected among the FCC
Licenses were granted on a site-specific basis and authorized only analog
operations. No waiver of the traditional one-year construction deadline was
requested or granted. Other analog licenses among the FCC Licenses may appear on
the FCC's database as owned by Nextel, but because Nextel has not yet closed on
the purchase and sale of the facility, it may still be deemed subject to a
Nextel management agreement and therefore not qualified for assignment from
Nextel to any third party. Nextel is currently working to resolve these issues
by closing on the related transactions.

      2. Chadmoore Request for Finders Preference against Southeast Wide Area
Licenses: On September 18, 1995 Chadmoore Communications ("Chadmoore") filed a
request for a finder's preference (the "Chadmoore Request") against the
"wide-area" authorizations initially granted to Transit Communications
("Transit"), which were subsequently assigned to Dial Call, Inc. and then
assigned to Nextel. (Case No. 95F860). The Chadmoore Request alleged that
Transit misrepresented the number of analog channels it had constructed on
several analog stations, and that therefore the resulting wide-area grants on
the same channels were improper. Chadmoore claimed that it should be awarded all
of the wide-area licenses that were granted to Transit and now held by Nextel.
Thus, if successful, Chadmoore may become a short-spaced co-channel licensee or
an incumbent licensee in areas where Nextel is either assigning wide-area
licenses or EA licenses as part of the FCC Licenses. In support of the Chadmoore
Request, Chadmoore incorporated by reference numerous finder's preference
requests filed against Transit's analog stations. The individual analog requests
were filed by Chadmoore itself and by Peacock's Radio and Wild's Computer,
Partnership ("Peacock"). On November 22, 1995, Dial Call, Inc. filed a Motion to
Dismiss demonstrating numerous procedural defects with Chadmoore's filing.
Chadmoore opposed the Motion. On January 31, 1997, the FCC requested further
information from Nextel regarding Chadmoore's substantive allegations. On March
18, 1997, Nextel responded. Chadmoore replied to Nextel's filing on April 7,
1997. The Motion to Dismiss has not been ruled upon by the FCC and the FCC has
not reached a decision in this proceeding. Further, through an agreement between
Nextel and Peacock, Peacock has withdrawn 33 of the analog finder's preference
requests that it had filed against the Transit stations. The FCC announced the
withdrawal of the 33 Peacock cases by Public Notice, dated June 30, 1999 (DA
99-1123).

                  Part II: Issues Affecting Individual Licenses

1.    WPDX385 in Worthington, IN (861, 863, 864, 865.1125, 862.6125): Nextel and
      the former licensee have not yet consummated the transaction. Thus, Nextel
      is not yet the legal owner of the subject facility. Nextel expects to
      close the transaction in due course. Until consummation of the underlying
      transaction, Partner is subject to the FCC's rules regarding protection of
      "incumbent" SMR licensees.

2.    WPLM745 (C Block EA License)/KNRU551, Clay City, IN (865.7375): The
      KNRU551 865.7375 MHz channel is not on the list of assets to be assigned.
      On July 16, 1997, Nextel filed an informal request for reinstatement of
      channel 865.7375 MHz due to an error by the FCC in superseding the
      license. The FCC has yet to act on this request. However, Nextel was
      awarded and is assigning the C Block EA license (WPLM745) to Partner. To
      moot this issue, Nextel will withdraw its informal request for action with
      the FCC to clear use of this channel pursuant to the EA license and to
      make clear that the KNRU551 license is no longer subject to any
      reinstatement request.

                               Supplement No. 1 to
                iDEN Infrastructure Equipment Purchase Agreement

      This SUPPLEMENT NO. 1 TO iDEN INFRASTRUCTURE EQUIPMENT PURCHASE AGREEMENT
(this "Supplement") is made as of the 9th day of September, 1999, between
Motorola, Inc., a Delaware corporation, by and through its Network Solutions

Delaware corporation, with offices at 4500 Carillon Pt., Kirkland, Washington
98033 ("Customer").

      WHEREAS, Motorola and Customer are all of the parties to that certain iDEN
Infrastructure Equipment Purchase Agreement dated January 29, 1999 (the
"Agreement"), which provides for the sale to and purchase by Customer from
time-to-time of certain equipment, products and services;

      WHEREAS, Section 7.6 of the Agreement grants to Customer the Equipment
Credit in the amount and to purchase the items set forth therein in exchange for
the issuance to Motorola of equity interests of Customer, all in accordance with
the terms of the Subscription and Contribution Agreement of even date therewith
between Nextel Partners, Inc., a Delaware corporation and the parent of Customer
("Partners"), and each of the investors named therein;

      WHEREAS, each of Motorola and Customer currently desires to supplement the
Agreement to grant to Customer an additional equipment credit in the amount and
to purchase the items set forth herein in exchange for the issuance to Motorola
of additional equity interests of Customer, all in accordance with the terms of
the Expansion Subscription and Contribution Agreement of even date herewith
between Partners and each of the investors named therein (the "Expansion
Subscription Agreement");

      The parties hereto agree to supplement the Agreement as follows:

shall have the meanings ascribed to them under the Agreement.

      2. Additional In-Kind Capital Contribution. As a result of the issuance of

<PAGE>

Forty Four Thousand Seventy-Nine and 00/000 Dollars ($3,644,079.00) that may be
used as set forth below:

Upon the placing of each order in accordance with the terms of the Agreement,
the parties shall calculate the percentage of the total dollar value of the

payment thereafter on such order, for as long as either the Equipment Credit or
the Additional Equipment Credit is still in existence, shall be made by a
combination of cash and either the Equipment Credit or the Additional Equipment
Credit. The cash amount shall be (100% - EBTS percentage) x payment due. The
Equipment Credit or the Additional Equipment Credit shall be the EBTS percentage
x payment due, and the Equipment Credit or the Additional Equipment Credit shall
be reduced by a like amount. Customer may at any time choose to apply less than
the above stated maximum Equipment Credit amount or the above stated maximum
Additional Equipment Credit amount to any order and increase the cash portion.

      3. Expansion Subscription Agreement. The execution and delivery of the
Expansion Subscription Agreement by each of Motorola and Customer is a condition
precedent to the obligations of the parties hereunder.

      4. Ratification of Agreement. As supplemented hereby, the Agreement and
its terms and provisions are hereby ratified and confirmed for all purposes and
