                               EXPANSION TERRITORY
                              MANAGEMENT AGREEMENT
                                    (Interim)

      THIS MANAGEMENT AGREEMENT (the "Agreement") is made and entered into as of
September 9, 1999, by and between Nextel Partners Operating Corp., a Delaware
corporation, on behalf of itself and its wholly owned subsidiaries (the
"Manager"), and Nextel WIP Corp., a Delaware corporation (the "Licensee").
Licensee is an indirect wholly owned subsidiary of Nextel Communications, Inc.
("Nextel"). Manager and Licensee are hereinafter collectively referred to as the
"Parties."

                                    RECITALS

      A. Licensee has the right to use Federal Communications Commission (the
"FCC") Licenses (as defined below), held by one or more direct or indirect,
wholly owned subsidiaries of Nextel, to operate on the frequencies identified on
Attachment A hereto.

      B. On January 29, 1999, the Parties and Nextel Partners, Inc., a Delaware
corporation that owns all of the outstanding stock of Manager ("NPI") entered
into the JV Agreement (as defined below) and other Operating Agreements (as
defined below) to enable Nextel to expand and enhance the geographic coverage of
its existing nationwide digital iDEN Specialized Mobile Radio ("SMR") network.

      C. Manager and NPI have elected to expand and market Nextel's iDEN
wireless telecommunications services in the Expansion Territory (as defined
below) pursuant to the JV Agreement.

      D. Simultaneously with the execution of the Agreement, Licensee will file
an appropriate application with the FCC for approval to transfer all the capital
stock of Expansion Co. (as defined below) to Manager.

      E. Pursuant to other agreements, Nextel will maintain its approximate 34
percent equity interest in NPI in exchange for (among other things) authorizing
Manager, pursuant to prescribed terms, conditions, standards and procedures, to
manage the use of the frequencies authorized by the Licenses to build and
operate in the Expansion Territory an iDEN digital wireless communications
system interoperable with Nextel's national network, and to provide roaming
services to each other's customers

      F. The corporate governance of NPI is by a Board of Directors (the
"Board") with a minimum of five members. Nextel has the right to designate one
Board member.

      G. Pursuant to NPI's Restated Certificate of Incorporation and the JV
Agreement, for so long as Licensee owns an equity interest in NPI, without
Licensee's prior written approval neither NPI nor Manager will make any
decision: (1) to make a material change in technology;
<PAGE>


(2) to allow a sale, exchange or other disposition of all or substantially all
of its assets; or (3) to expand or broaden the scope of NPI's business beyond
the business described in Section 2.1 of the JV Agreement, including without
limitation, any decision to make any acquisition other than 800 MIHz or 900 MHz
SMR acquisitions within the term or renewal term of the JV Agreement.

      H. Licensee has the option to acquire all ownership of NPI under certain
circumstances, and Licensee may have the right to acquire additional equity
interests in NPI, or be required to make additional contributions in exchange
for additional equity interests in NPI.

      I. Licensee and Manager have each independently determined that their
respective business interests are best served by entering into this Agreement;
that Manager, in accordance with this Agreement, can build and implement iDEN
service in mid-sized and smaller cities more rapidly than Nextel acting alone,
and that the joint venture will expeditiously bring Nextel's unique wireless
communications services to persons living and working in the Expansion Territory
(as defined below) thereby facilitating expeditious deployment of Nextel's brand
of services on a ubiquitous nationwide basis.

      J. The Parties are familiar with the FCC's rules and policies concerning
the responsibilities of SMR and Commercial Mobile Radio Service ("CMRS")
licensees and have structured this Agreement to be in compliance therewith.

                                    AGREEMENT

      NOW, THEREFORE, in consideration of the covenants hereinafter set forth,

acknowledgment of such renewal.

            3. System Management Responsibilities. Pursuant to this Agreement,

Expansion Territory pursuant to the specifications, operating and quality
standards and implementation timelines established by Licensee and set forth in

                                     - 3 -
<PAGE>

      4. Brand Name.

            a. Manager is required to use the Nextel brand name and other Nextel
trademarks to market digital iDEN services provided on Licensee's spectrum in
the Expansion Territory, subject to Nextel's standards and restrictions for use
of this intellectual property. In the event Nextel makes a material change in
its brand identity, Manager is required to implement such change as set forth in
the JV Agreement.

            b. Nextel retains the exclusive right to advertise in national
publications or other national media. Manager's advertising is required to be
consistent with specific creative standards for advertising, which will be
substantially identical to those used by Nextel and its subsidiaries operating
an iDEN network in the United States. Manager may not deviate from such creative
standards unless it obtains Licensee's prior approval.

      5. Licensee's System Standards. In carrying out the responsibilities
described in Paragraph (3) above, Manager must comply with the JV Agreement and
the other Operating Agreements setting forth Licensee's performance standards
and requirements to assure compatibility with Nextel's nationwide iDEN network
and a consistent level of customer service and satisfaction for services and
products using frequencies authorized to the Licensee and using the Nextel
brand. Subject to the more specific terms and conditions set forth in the JV
Agreement and the Collateral Agreements, Manager must comply with the
Licensee-specified standards and requirements described below (as they may be
modified from time to time pursuant to the JV Agreement and the Collateral
Agreements).

            a. Required Services. Manager is required to offer all customers
operating in the Expansion Territory the products, services and capabilities
specified in Exhibit 6.1 of the JV Agreement as fundamental to Nextel's overall
product and service strategy. If Nextel provides a required service nationally,
Manager must implement the service; if Nextel provides the service in selected
areas, Manager must provide the service in comparable service areas in the
Expansion Territory, in each case no more than six months from Licensee
designating it a required service, or whenever a Nextel subsidiary implements
the service in comparable service areas, whichever occurs last.

            b. Build-Out and Target Launch Dates. Manager must comply with
specific target dates for initial build out and for launching service in areas
within the Expansion Territory. This includes providing coverage to specific
areas and corridors. Prior to offering commercial service in an area, Manager
must notify Licensee at least 60 days prior to the proposed launch date at which
time Licensee has the right to promptly review Manager's operations for that
area in order to validate Manager's compliance with all launch criteria.

            c. Frequency Design Standards. Manager is required to adhere to
Nextel-specified standards for use of the radio frequencies subject to the
licenses in the Expansion Territory. Licensee has the right to regularly monitor
the frequency designs and actual frequency signal performance levels to assure
compliance with such standards.


                                     - 4 -
<PAGE>

            d. Site Acquisition Standards. Manager must adhere to
Nextel-specified site acquisition standards. Licensee will have the right to
regular review of internal documents relating to such sites, including site
leases, title documents and other compliance documents to assure compliance with
such standards.

            e. System Construction Standards. Manager must adhere to
Nextel-specific cell site construction standards, and, subject to the provisions
of the JV Agreement, Manager is required to choose from among a group of
Nextel-approved cell site equipment vendors. Licensee has the right to inspect
cell sites in the Expansion Territory to ensure compliance.

            f. Telco Standards. Manager is required to comply with telephone
network interconnection requirements including the types of interconnection
permitted, the requirements for contracts with interconnecting
telecommunications providers and the manner in which such interconnections are
made both from cell sites to Nextel's mobile switching centers ("MSCs") and
DAPs, and to the public switched telephone network.

            g. Access to Switching Facilities. Manager and Licensee will
cooperate to establish the optimum switch configuration for the Territory
(including the Expansion Territory) and to deploy DAPs so as to allow both
parties to provide seamless Direct Connect coverage to logical communities of
interest. This may include sharing switches or DAPs. Manager will participate in
regular meetings and planning with Licensee for overall network configuration
and will provide monthly forecasts of expected cell site build out and customer
traffic growth as described in the JV Agreement.

            h. Network Performance Requirements. To maintain the integrity of
Nextel's national network and reputation in the marketplace, Manager must meet
specific criteria as specified in the Collateral Agreement or JV Agreement
related to the performance of the iDEN network and the level of customer
satisfaction. Manager will be required to measure and provide periodic reporting
of its performance in a format satisfactory to Licensee.

            i. Customer Care Standards. Manager is responsible for providing a
minimum level of care to its customers and to use customer satisfaction
monitoring systems or vendors to carry out this function as specified in the JV
Agreement. Additionally, in order to maintain a consistent "back office"
operating process and exchange of network, operating and customer information,
Manager may be required to use Nextel's "back office" systems platform for
activities such as order entry, order management, inventory management, customer
provisioning, and the production of call detail records for billing purposes.

            j. Service and Equipment Pricing. Manager is permitted to manage the
use of the Licenses only for services that adhere to the service pricing
structure specified in the JV Agreement that Nextel considers fundamental to its
brand identity and that differentiates Nextel's services among wireless
communications providers. Manager will have the opportunity to participate in
discussions concerning modifications to the specific pricing structures and
introducing new specific pricing structures, but final decisions relating to
pricing structures will


                                     - 5 -
<PAGE>

be in Licensee's sole discretion. Manager will be responsible for setting local
pricing plans consistent with Licensee's service pricing structure, as described
above.

      6. FCC Compliance. The parties will comply with all applicable FCC rules
and regulations governing the Licenses or the Systems. Without limiting the
generality of the foregoing:

            a. Licensee, at all times during which it continues to hold the
Licenses through its ownership of all of the capital stock of Expansion Co.,
retains ultimate supervisory control over the use of the Licenses. Manager will
not represent itself as the federal licensee of SMR service offered on the iDEN
systems in the Expansion Territory or otherwise on Nextel's nationwide iDEN
network.

            b. With appropriate notice to, consultation with and participation
by Manager, Licensee will represent Manager (i) before all state regulatory
agencies with respect to matters within such agencies' jurisdiction that require
the representation or appearance of the owner of the Licenses and that have not
been or cannot be delegated to Manager pursuant to paragraph c. below; and (ii)
before the FCC with respect to any matters relating to the Licenses, the
operation of the systems in the Expansion Territory as it relates to any FCC
rules, regulations, policies or provisions of the Communications Act of 1934, as
amended, and any FCC correspondence and filings. Licensee will, with the
assistance and cooperation of Manager, take all actions necessary to keep the
Licenses in force and shall timely prepare and submit to the FCC or any other
relevant governmental authority all reports, applications, renewals, filings or
other documents necessary to keep the Licenses and any certificates of public
convenience and necessity or other state regulatory approvals in force and in
good standing.

            c. Nothing in the preceding paragraph precludes Licensee from
delegating to Manager responsibility to obtain and maintain in good standing all
business licenses required by state, local or municipal governments, to file
annual or other reports required by such governments, and to prepare and file
all federal, state and local tax returns and tax payments. Additionally,
Licensee will require Manager to assure that the iDEN systems in the Expansion
Territory comply with all applicable governmentally-mandated regulatory programs
including, but not limited to, Federal Universal Service Fund assessments, state
universal service programs, Enhanced 911, Telecommunications Relay Services for
the Speech and Hearing Impaired, local number portability, calling party pays
services, and priority access requirements. Such compliance may include
collecting applicable fees from subscribers and payment of governmental
assessments for such programs.

            d. Nothing in this Agreement or the Operating Agreements is intended
to diminish or restrict Licensee's (or any other wholly owned Nextel
subsidiary's) obligations as an FCC licensee and both parties desire that this
Agreement be in compliance with the rules and regulations of the FCC. In the
event that the FCC determines that any provision of this Agreement violates any
FCC rule, policy or regulation, both parties will implement in good faith the
provisions of the Operating Agreements consistent with the intent of this
Agreement to be in compliance with FCC rules, policies and regulations. In the
event of a dispute between the parties about such implementation, the dispute
will be resolved under the applicable provisions


                                     - 6 -
<PAGE>

of the JV Agreement (which may, depending on the relevant circumstances, include
Section 4.12C and/or Article 12 of the JV Agreement).

      7. Systems Revenues and Expenses. Manager will independently finance its
build-out and operations. Manager will collect all revenues from the operation
of the iDEN systems in the Expansion Territory, subject to the terms of the
Operating Agreements. Licensee will benefit from these revenues by virtue of its
equity interest in NPI.

      8. Termination. This Agreement will terminate upon the occurrence of any
of the following:

            a. If Licensee acquires all equity ownership of NPI under the
Shareholders' Agreement, or the charter documents of NPI or otherwise.

            b. Termination of the JV Agreement.

            c. The FCC approves the transfer of all of the capital stock of
Expansion Co. to Manager, or Manager otherwise becomes the holder, or the
beneficial owner of all of the capital stock of the holder, of the Licenses.

      9. Notices. Any notice, request or other communication required or
permitted hereunder must be in writing and shall be deemed given: (a) when
received if personally delivered; (b) within 5 days after being sent by
registered or certified mail, return receipt requested, postage prepaid; (c)

within 1 business day of being sent by priority delivery by established
overnight courier, to the parties at their respective addresses set forth below.

9 may change the address or the persons to whom notices or copies thereof are to

      10. Waivers; Amendment. Except as otherwise provided in this Agreement,
any party may waive, in writing, compliance by the other party thereto (to the
extent such compliance is for the benefit of the party giving such waiver) with
any of the terms, covenants or conditions contained in this Agreement (except as
may be imposed by law). Any waiver by any party of any violations of, breach of,
or default under, any provision of any of this Agreement, by any other party
will not be construed as, or constitute, a continuing waiver of such provision,
or waiver of any other violation of, breach of, or default under, any other
provision of this Agreement. This Agreement may be amended only by a writing
executed by the parties.

      11. Successors and Assigns. Manager's rights and obligations under this
Agreement are personal to Manager and Manager may not assign any rights or
delegate any duties under this Agreement except to a direct or indirect wholly
owned subsidiary (with which Manager agrees to remain jointly and severally
liable for performance of its obligations hereunder). Licensee may not assign
its rights herein except to a wholly-owned subsidiary of Licensee, or in
accordance with the provisions of Section 13.7 of the JV Agreement.

      12. Governing Law; Severability. This Agreement is governed by and is to
be construed in accordance with the laws of the State of New York, except as to
matters governed by the rules and regulations of the FCC or the Communications
Act of 1934, as amended, which shall be governed thereby. In the event that any
provision herein is held to be invalid, void or illegal by the FCC or any court
of competent jurisdiction, the remaining provisions of this Agreement shall
remain in full force and effect and this Agreement is to be construed to
preserve the original intent of the parties hereto insofar as practical.

      13. Counterparts. This Agreement may be executed in one or more
counterparts, each of which is an original, but all of which together constitute
one and the same instrument.

      14. Interpretation. a. This Agreement has been prepared and negotiations
in connection herewith have been carried on by the joint efforts of the parties.
This Agreement is to be construed fairly and simply and not strictly for or
against either of the parties hereto.

            b. The headings contained in this Agreement are solely for
convenience of reference and are not given any effect in the construction or
interpretation of this Agreement.

            c. This Agreement, including, without limitation, Sections 4 and 5,
contains descriptions of certain rights and obligations of the parties that are
more specifically detailed in the JV Agreement, the Operating Agreements and the
Shareholders' Agreement (together with the JV Agreement and the Operating
Agreements, the "Other Agreements"). In the event of any inconsistency between
the summary descriptions (including, without limitation, those in Sections 4 and
5 of this Agreement), and the corresponding provisions in the Other Agreements,
the provisions of the Other Agreements control. In the event that there are
additional provisions in the Other Agreements that supplement the summary
descriptions of this Agreement, the additional provisions of the Other
Agreements control.

      15. Entire Agreement This Agreement and the Other Agreements embody the
entire agreement and understanding between the parties hereto relating to the
subject matter
