      such released Shares and shall deliver such certificate to the Purchaser.

      Escrowed Shares only in accordance with this Agreement or upon receipt of
      instructions signed by both parties. In the event further instructions are
      desired by the Escrow Agent, he shall be entitled to rely upon directions
      executed by a majority of the authorized number of the Company's directors
      (excluding the Purchaser if he is then a member of the Board). The Escrow
      Agent shall have no liability for any act or omission hereunder while
      acting in good faith in the exercise of his own judgment, and shall be
      entitled to indemnification from the Company to the full extent permitted
      by applicable law in respect of his service as Escrow Agent.

            (c) If the Company or any assignee repurchases Shares pursuant to
      Section 4, the Escrow Agent, upon receipt of written notice of such
      exercise from the proposed transferee, shall take all steps necessary to
      accomplish such transfer.

            (d) Subject to the terms hereof, the Purchaser and each of his
      permitted assigns shall, as a record owner of Shares, have all the rights
      of a stockholder with respect to the Escrowed Shares while they are held
      in escrow or otherwise held in accordance with this Section 5, including

      accordance with this Section 5. If, from time to time prior to the
      termination of the Company's repurchase rights, there is (i) any stock

                                                                               8

      sale of all or substantially all of the assets or other acquisition of the
      Company, any and all new, substituted or additional securities to which
      the Purchaser is entitled by reason of his ownership of Escrowed Shares

      the following legend (and any other legend required to be placed thereon
      by applicable state securities laws):

      THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
      INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR
      DISTRIBUTION THEREOF. NO SUCH SALE OR DISPOSITION MAY BE EFFECTED WITHOUT
      AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF
      COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED
      UNDER THE SECURITIES ACT OF 1933.

      In addition, the certificates evidencing the Escrowed Shares shall be
endorsed with the following legend:

      THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY IN
      ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY AND THE
      STOCKHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY.

            (b) Except as otherwise permitted by, and subject to the provisions
      of each of, this Agreement, any stockholders' agreement to which the
      Purchaser is a party, the restated certificate of incorporation of the
      Company, as amended from time to time, or the Purchaser's employment
      agreement with the Company or a subsidiary of the Company, none of the
      Escrowed Shares (or any beneficial interest therein) shall be transferred,
      encumbered or otherwise disposed of in any way.

      7. Adjustments for Splits, Etc. All references to the number of Shares and
the purchase price of the Shares in this Agreement shall be automatically
adjusted to reflect any stock split, stock dividend or like change in the shares
of Class A Common Stock which may be made by the Company after the date of
purchase of the Shares.

      8. Investment Representations; Restriction on Transfer. In connection with
the purchase of the Shares, the Purchaser represents to the Company the
following:

            (a) He is aware of the Company's business affairs and financial
      condition and has acquired sufficient information about the Company to
      reach an informed and knowledgeable decision to acquire the Shares. He is
      purchasing these securities for

                                                                               9
<PAGE>

      investment for his own account only and not with a view to, or for resale
      in connection with, any "distribution" thereof within the meaning of the
      Securities Act.

            (b) He understands that the Shares have not been registered under
      the Securities Act by reason of a specific exemption therefrom, which
      exemption depends upon, among other things, the bona fide nature of his
      investment intent as expressed herein. In this connection, he understands
      that, in the view of the SEC, the statutory basis for such exemption may
      not be present if his representations meant that his present intention was
      to hold these securities for a minimum capital gains period under the tax
      statutes, for a deferred sale, for a market rise, for a sale if the market
      does not rise, or for a year or any other fixed period in the future.

            (c) He further acknowledges and understands that the Shares must be
      held indefinitely unless they are subsequently registered under the
      Securities Act or an exemption from such registration is available. He
      understands that the certificate evidencing the Shares will be imprinted
      with a legend which prohibits the transfer of the Shares unless they are
      registered or such registration is not required in the opinion of counsel
      for the Company.

            (d) The Purchaser is an "accredited investor" within the meaning of
      Regulation 501 under the Securities Act of 1933, as amended, in that he is
      an "executive officer" as defined in Regulation 501 or otherwise is an
      "accredited investor", the Purchaser is aware that the Company is a
      "development stage" company with no significant business operations or
      history and may be dependent for its future success on matters that cannot
      now be foreseen or predicted, and the Purchaser is not making this
      investment in the Company based on any representation or warranty made to
      him by the Company.

            (e) The Purchaser's financial situation is such that the Purchaser
      can afford to bear the economic risk of holding the Shares acquired
      hereunder for an indefinite period of time, the Purchaser has adequate
      means for providing for his needs and contingencies and can afford to
      suffer the complete loss of the investment in the Shares.

            (f) The Purchaser's knowledge and experience in financial and
      business matters are such that he is capable of evaluating the merits and
      risks of the investment in the Shares, or the Purchaser has been advised
      by a representative possessing such knowledge and experience.

            (g) The Purchaser understands that the Shares 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 Shares, and that for an indefinite period
      following the date hereof there will be no (or only a limited) public
      market for the Shares and that, accordingly, it may not be possible for
      Purchaser to sell the Shares in case of emergency or otherwise.

                                                                              10
<PAGE>

            (h) The Purchaser and his representatives, including his
      professional, financial, tax and other advisors, have carefully reviewed
      all documents available to them in connection with the investment in the
      Shares, and the Purchaser understands and has taken cognizance of all the
      risks related to such investment.

            (i) The Purchaser and his representatives have been given the
      opportunity to examine all documents and to ask questions of, and to
      receive answers from, the Company and its representatives concerning the
      terms and conditions of the acquisition of the Shares and related matters
      and to obtain all additional information which the Purchaser or his
      representatives deem necessary.

            (j) All information that the Purchaser has provided to the Company
      and its representatives concerning the Purchaser and his financial
      position is true, complete and correct.

      9. General Provisions.

            (a) This Agreement shall be governed by the internal laws of the
      State of Delaware without regard to conflicts of law principles.

            (b) This Agreement, as amended and restated, represents the entire
      agreement between the parties with respect to the purchase of the Shares
      by the Purchaser and may be modified or amended only by a writing signed
      by both parties.

            (c) All notices given hereunder shall be in writing and shall be
      deemed to have been duly given and received (i) when delivered personally,

      paid, return receipt requested), (iii) one business day after being sent
      by a reputable overnight delivery service, postage or delivery charges
      prepaid, or (iv) on the date on which a facsimile is transmitted, in each
      case to the parties at their respective addresses stated below; provided,
      that if the intended recipient of any notice hereunder refuses to
      acknowledge receipt thereof in writing, such notice shall be deemed to
      have been duly given on the date of such refusal. Any party may change its
      address for notice by giving notice of the new address to the other party
      in accordance with the provisions of this paragraph.

                If to Executive:

                    Barry L. Rowan

            (d) The rights and obligations of the Purchaser under this Agreement
      may be assigned only with the prior written consent of the Company.

            (e) Either party's failure to enforce any provision of this
      Agreement shall not in any way be construed as a waiver of any such
      provision, nor prevent that party thereafter from enforcing each and every
      other provision of this Agreement. The rights granted both parties herein
      are cumulative and shall not constitute a waiver of either party's right
      to assert all other legal remedies available to it under the
      circumstances.

            (f) Each party agrees, upon the reasonable request of the other
      party, to execute any further documents or instruments necessary or
      desirable to carry out the purposes or intent of this Agreement.

            (g) Except as otherwise provided herein, any controversies or claims
      arising out of, or relating to this Agreement or the breach thereof, shall
      be settled by arbitration in accordance with the commercial rules of the
      American Arbitration Association, which decision shall be final and
      binding on the parties, and judgment upon the award rendered shall be
      entered in any court having jurisdiction thereof. The arbitrator shall be
      selected in a manner that is mutually agreeable to the Company and the
      Purchaser. Any party may demand such arbitration in accordance with the
      procedures set out in those rules. The arbitration shall be conducted in
      New York, New York, or such other location as may be mutually agreed upon
      by the parties. Special, consequential, or punitive damages shall not be
      awarded by the arbitrator. In the event of any arbitration proceeding
      hereunder, the Company will (x) pay the fees and expenses of the
      arbitrator and (y) advance the Purchaser's documented out-of-pocket costs
      (including reasonable counsel fees and expenses) on a current basis,
      provided, that if the Purchaser is determined not to be the substantially
      prevailing party on the matters submitted for arbitration (which
      determination shall be made by the arbitrator and included in his or her
      decision), the Purchaser will promptly reimburse the Company for any
      expenses so advanced. The Purchaser acknowledges that the Company is
      agreeing to make advances to him pursuant to the preceding sentence in
      consideration of his agreement to reimburse the Company for any such
      advances to the extent required by the preceding sentence. The Company
      will in all events pay its own costs (including counsel fees and expenses)
      in connection with any arbitration proceeding hereunder.

            (h) The Purchaser understands that he (and not the Company) shall be
      responsible for his own federal, state, local or foreign tax liability and
      any of his other tax consequences that may arise as a result of the
      transactions contemplated by this

                                                                              12
<PAGE>

      Agreement. The Purchaser shall rely solely on the determinations of his
      tax advisors or his own determinations, and not on any statements or
      representations by the Company or any of its agents, with regard to all
      such tax matters. The Purchaser shall notify the Company and Nextel
      Partners Operating Corp. in writing if the Purchaser files an election
      pursuant to Section 83(b) of the Internal Revenue Code of 1986, as
      amended, with the Internal Revenue Service within 30 days from the date of
      the sale of the Shares hereunder; and the Company shall file its tax
      returns and reports in a manner consistent with such election, provided
      that such election is made on the basis disclosed to the Company. The
      Company intends, in the event it does not receive from the Purchaser
      evidence of a proper filing, to claim a tax deduction for and to calculate
      and withhold taxes on any amount which would be taxable to the Purchaser
      in the absence of such an election.

            (i) To the extent legally required, the Company shall have the right
      and is authorized to withhold from any payments due or transfers in
      connection with the purchase of the Shares hereunder or from any
      compensation or other amount owing to the Purchaser the amount (in cash,
      Shares, other securities or other property) of any applicable withholding
      taxes in respect of the Shares and to take such other action as may be
      necessary in the opinion of the Company to satisfy all obligations for the
      payment of such taxes, if applicable.

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

                  AMENDED AND RESTATED AS OF FEBRUARY 24, 2005

      This Employment Agreement, dated as of February 24, 2005 is entered into
between Nextel Partners Operating Corp., a Delaware corporation, Nextel
Partners, Inc., a Delaware corporation (collectively the "Company"), and Dave
Aas, ("Executive").

      WHEREAS, the Company desires to employ Executive and to enter into an
agreement embodying the terms of such employment (the "Agreement"), and
Executive desires to accept such employment and enter into this Agreement.

      NOW, THEREFORE, in consideration of the mutual covenants herein contained,
the Company and Executive, intending to be legally bound, hereby agree as
follows:

      1. Employment.

            (a) Agreement to Employ. Upon the terms and subject to the
conditions hereof the Company shall employ Executive as Vice President and Chief
Technology Officer of Nextel Partners, Inc. and Nextel Partners Operating Corp.
until the Expiration Date (as defined in Section 1(b)), any date to which this
Agreement shall have been extended pursuant to section 1(b) or any earlier
termination of this Agreement pursuant to the provisions hereof. Executive's
office shall be located in the Seattle, Washington metropolitan area. During the
term of his employment hereunder, Executive will devote substantially all of his
business time to the performance of his duties hereunder.

            (b) Employment Period. Unless earlier terminated pursuant to the
provisions hereof, the initial term of Executive's employment with the Company
shall be for a period of one year commencing on the date of this Agreement and
continuing until February 24, 2006 (the "Expiration Date"). The term of this
Agreement shall automatically extend for successive one-year terms commencing on
the Expiration Date unless Executive or the Company's board of directors
provides written notice to the other party at least thirty (30) calendar days
prior to the end of the then current term indicating that the party giving
notice does not wish to extend the Agreement. In such event, the Agreement shall
terminate at the end of the then current term.

      2. Responsibility. Executive shall be responsible for the establishment,
maintenance and operation of all engineering, system development, information
technology and technical operations at the Company and for such other duties
commensurate with his position that may be assigned from time to time by the
Company's board of directors or the Company's chief executive officer (to the
extent not inconsistent with the duties assigned to him by the board of
directors). Executive shall report directly to the chief executive officer and
shall be subject to his supervision and the overall supervision of the board of
directors.

<PAGE>

      3. Compensation and Benefits.

            (a) Salary, Bonus and Benefits.

                  (i) The Company shall pay Executive a base salary in the
annual amount of $290,000 payable bi-weekly or in such other manner as is
consistent with the Company's normal payroll practices.

                  (ii) The Company shall (subject to the review and approval by
the compensation committee of the board of directors) establish a performance
based program pursuant to which Executive shall receive, if performance targets
are met, an additional annual cash payment of up to seventy-five percent (75%)
of Executive's then current base salary (or such higher amount as the
compensation committee may approve).

                  (iii) The Company shall offer to Executive a benefits package
equivalent to that provided to the Company's other employees and senior-level
executives (including, without limitation, participation in the Company's
medical, dental, vision, life and disability insurance programs, the Company's
401(k) plan, the Company's stock purchase program, and such other plans or
programs as may be made available). In addition, the Company shall maintain a
life insurance policy on the life of Executive and payable upon death of the
Executive to a beneficiary or beneficiaries designated by Executive, in an
amount not less than $500,000.

                  (iv) For so long as this Agreement is renewed, the
compensation committee of the board of directors shall each year on or before
the anniversary date of this Agreement review the Executive's base salary and
bonus payment in light of the performance of Executive and the Company, and may
increase (but not decrease) such base salary and bonus payment by an amount it
determines to be appropriate.

            (b) Expenses. Executive shall maintain his own automobile and shall
carry liability insurance in the minimum amount of $300,000. The Company shall
reimburse Executive monthly for business use of his automobile at the prevailing
IRS rate per mile. Executive shall also be reimbursed monthly for all other
reasonable out-of-pocket expenses incurred or paid by Executive while
representing the Company or conducting Company business. Executive shall be
responsible for maintaining records reasonably satisfactory to support all
claimed business usage of his automobile and to substantiate all out-of-pocket
expenses incurred for which reimbursement is sought and shall furnish such
records to the Company in accordance with its policies.

            (c) Vacation. Executive shall be entitled to 15 vacation days each
calendar year, any or all of which may be carried over into a new calendar year,
for a maximum accrual of 30 days. Executive shall also be entitled to any paid
or unpaid holidays provided by the Company in accordance with its generally
applicable personnel policies. Upon termination of Executive's services under
this Agreement, Executive will

<PAGE>

be paid for unused and accrued vacation time earned through the last completed
day of service.

            (d) Indemnification. The Company shall indemnify and hold Executive
harmless in accordance with the terms of the Company's certificate of
incorporation and bylaws, in each case as in effect on the date hereof.

            (e) D&O Insurance. The Company shall maintain directors and
officers' liability insurance coverage covering Executive in amounts customary
for similarly situated companies in the telecommunications industry and with
reputable insurers. All such policies shall provide for coverage to Executive on
the same terms and conditions applicable to the coverage provided under such
policies to the Company's other directors and officers.

      4. Nondisclosure of Proprietary and Confidential Information.

            (a) Confidential Information. Executive agrees to refrain (whether
during or after his employment with the Company) from disclosing or using,
except as permitted by this Agreement or otherwise authorized by the Company's
board of directors, any secrets or confidential information with respect to the
Company or any of the Company's direct or indirect wholly owned subsidiaries
(collectively the "Covered Entities"), including without limitation its trade
secrets, patents, affairs, business plans, strategic, commercial or financial
information other than information that is or becomes publicly available through
no fault of Executive (the "Confidential Information"). Confidential Information
may be used solely for the benefit of the Company, and Executive shall not make
any other use of such information. Executive agrees that all materials relating
to the business of any Covered Entity that are provided or made available to
Executive, or created by Executive, during the course of Executive's services to
the Company shall be and remain the property of the Company and/or the
applicable Covered Entity (subject to the terms of any separate agreement
between the Company and/or the affected Covered Entity), whether or not such
materials constitute or contain Confidential Information, and all copies of such
materials shall be returned to the Company immediately upon the termination of
Executive's services to the Company. In the event that the Company notifies the
Executive that it has entered into a confidentiality agreement with a Covered
Entity or with any affiliate of the Company with respect to confidential
information provided to the Company, the Executive shall comply with such
reasonable obligations thereunder as are applicable to the Executive.

            (b) Innovations; Inventions. Executive hereby sells, transfers and
assigns to the Company all right, title and interest of Executive in and to any
and all inventions, ideas, disclosures and improvements of any kind or nature
whatsoever, whether patented or unpatented, and any and all copyrightable
materials, in either case whether made or conceived in whole or in part by
Executive alone or together with others during the initial term of this
Agreement or any renewal term, that (i) relate to any methods, designs,
products, processes, apparatus, service or devices sold, leased used or under
construction or development by the Company or the Covered Entities, (ii) relate
to the business,

<PAGE>

functions or operations of the Company or the Covered Entities, or (iii) arise
from, in whole or in part, the efforts of Executive on behalf of the Company.
Executive will communicate and disclose to the Company promptly all information,
data and details pertaining to any inventions, ideas, disclosures and
improvements described above, in such form or format as the Company may
reasonably request. During the term of this Agreement or any renewal term and
thereafter, Executive will execute, acknowledge or deliver to the Company (at
the Company's expense) such formal transfers and assignments and such other
papers and documents as may be required of Executive to permit the Company to
file and prosecute any patent applications the Company desires to file and
prosecute relating to any of the foregoing, and, as to copyrightable material,
to obtain copyright thereon. Notwithstanding the foregoing, Executive
understands that this Agreement requires disclosure, but not assignment, of any
invention that qualifies under Section 49.44.140 of the Revised Code of
Washington, which provides, in part:

            (1) A provision in an employment agreement which provides that an
      employee shall assign or offer to assign any of the employee's rights in
      an invention to the employer does not apply to an invention for which no
      equipment, supplies, facilities, or trade secret information of the
      employer was used and which was developed entirely on the employee's own
      time, unless (a) the invention relates (i) directly to the business of the
      employer, or (ii) to the employer's actual or demonstrably anticipated
      research or development, or (b) the invention results from any work
      performed by the employee for the employer. Any provision which purports
      to apply to such an invention is to that extent against the public policy
      of this state and is to that extent void and unenforceable.

            (c) Notwithstanding the foregoing provisions of this Section 4 or
any other provision of this Agreement, nothing in this Agreement shall prohibit
or restrict Executive from: (i) providing information to, testifying or
otherwise assisting in any investigation or proceeding brought by any federal
regulatory or law enforcement agency or legislative body, or any self-regulatory
organization; (ii) providing information to or assisting in an investigation by
the Company's designated legal, compliance and/or human resources officers; or
(iii) testifying, participating or otherwise assisting in a proceeding relating
to an alleged violation of any federal, state or municipal law relating to fraud
or any rule or regulation of the Securities and Exchange Commission or any
self-regulatory organization.

      5. Non-Competition; Non-Solicitation.

            (a) In view of the unique value to the Company of Executive's
services and because of the Confidential Information to be obtained by or
disclosed to Executive as described above, Executive agrees that, during the
term of this Agreement and for a period of one year thereafter, provided that
this Agreement is not terminated by the Company without Cause (as defined below)
or by the Executive for Good Reason (as defined below):

<PAGE>

                  (i) Executive will not directly or indirectly assist or become
associated with any Communication Service Provider (as defined below) in any
business of such provider that competes in any of the markets of any of the
Covered Entities, whether as a principal, partner, employee, consultant or
shareholder (other than as a holder of less than 5% of the outstanding voting
shares of any publicly traded company);

                  (ii) Executive will not directly or indirectly solicit for
employment or employ any employee of any of the Covered Entities, unless such
solicited person shall have ceased to be employed by any such entity for a
period of at least six months; and

                  (iii) Executive will not directly or indirectly solicit
business from customers of any of the Covered Entities, provided that the
foregoing shall not restrict Executive or any entity with which Executive is
associated from soliciting or doing business with any customer of any of the
Covered Entities, if such solicitation does not interfere with any business
relationship between such solicited customer and any of the Covered Entities.

                  (iv) For purposes of this Agreement, the term "Communication
Service Provider" means and includes any entity that derives twenty-five percent
or more of its revenues from the provision of voice and/or data communication
services to businesses and/or consumers regardless of the technology used to
provide such services and specifically includes, without limitation, internet
service providers, cable, wireless, satellite, landline, voice over internet
protocol and fixed mobile entities.

            (b) If Executive violates any provision of Section 4 or Section
5(a), the Company shall be entitled to receive provable damages caused by such
breach, provided that Executive shall not be liable for indirect, special,
consequential or punitive damages (it being understood and agreed that this
remedy is in addition to, and not a limitation on, any injunctive relief or
other rights or remedies to which the Company is or may be entitled to at law or
in equity). Executive acknowledges and agrees that the Company's (and as
applicable, each Covered Entity's) remedies at law for a breach of any provision
of Section 4 or Section 5(a) would be inadequate and, in recognition of this
fact, Executive agrees that, in the event of such a breach, in addition to any
remedies at law, the Company and, as to Section 4, each Covered Entity, without
posting any bond, shall be entitled to obtain equitable relief in the form of
specific performance, temporary restraining order, temporary or permanent
injunction or any other equitable remedy which may then be available. As
provided in Section 10(i) hereof, the equitable remedies referenced in this
Section 5(b) shall be in addition to, and not in substitution for or exclusion
of, any other remedies available at law or in equity for any breach of either or
both of Sections 4 or 5. Executive and the Company each specifically acknowledge
and agree that the provisions of Sections 4 and 5 are for the express benefit of
each Covered Entity and that (i) no waiver, amendment or other modification of
Sections 4 or 5 with respect to a Covered Entity shall be effective unless it
has been consented to in writing by such Covered Entity, and (ii) each such
Covered Entity shall be entitled to enforce the provisions of Section 4 and/or 5
hereof (as appropriate) as fully and with the same rights and effect as if such
Covered Entity were a signatory party to this Agreement.

<PAGE>

            (c) If any provisions of Section 4 or Section 5(a) are held to be
invalid or unenforceable, the remaining provisions shall nevertheless continue
to be valid and enforceable as though the invalid or unenforceable parts had not
been included.

      6. Noncontravention. Executive represents and warrants to the Company that
Executive is free to enter into this Agreement and has no commitment,
arrangement or understanding to or with any party that restrains or is in
conflict with Executive's performance of the covenants, services and duties
provided for in this Agreement. Executive agrees to indemnify the Company and to
hold it harmless against any and all liabilities or claims arising out of any
unauthorized act or acts by Executive that, the foregoing representation and
warranty to the contrary notwithstanding, are in violation, or constitute a
breach of, any such commitment, arrangement or understanding.

      7. Termination. This Agreement shall automatically terminate (and the term
of this Agreement shall thereupon terminate) upon the occurrence of any one of
the following events:

            (a) Death. This Agreement shall terminate upon the death of
Executive.

            (b) Disability. This Agreement shall terminate upon the Executive's
disability if Executive shall have been incapacitated from illness, accident or
other disability and unable to perform his normal duties hereunder for a
cumulative period of three months in any period of six consecutive months, and
no reasonable accommodation being available, upon either party giving the other
party not less than 30 days written notice. In the event of a disagreement over
the nature of Executive's disability or the determination of whether Executive
is disabled, Executive agrees to be examined by a licensed physician that is
mutually agreeable to Executive and the Company.

            (c) Expiration of the Agreement. This Agreement shall terminate upon
the Expiration Date or the scheduled expiration date of any renewal or extension
thereof in compliance with Section 1(b).

            (d) Termination by the Company With Cause. This Agreement shall
terminate upon the Company's termination of Executive for Cause.

            (e) Voluntary Termination by Executive. This Agreement shall
terminate upon Executive's voluntary resignation; provided that Executive shall
provide the Company with no less than 30 days' written notice; provided,
further, that such voluntary resignation shall not relieve or release Executive
from any breach of this Agreement at or prior to the time of such resignation.

            (f) Termination by the Company Without Cause. This Agreement shall
terminate upon the Company's termination of Executive for any reason other than
for Cause; provided, that the Company shall provide Executive with no less than
30 days' written notice of any such termination. For purposes of this Agreement,
the Company's

<PAGE>

failure to renew the Agreement for any subsequent one-year term shall be deemed
to be a termination of Executive without Cause.

      (g) Termination by Executive for Good Reason. Upon the occurrence of any
event or the existence of any condition or circumstance constituting Good
Reason, Executive may by notice to the Board of Directors, deem a constructive
termination of this Agreement to have occurred.

      8. Effect of Termination.

            (a) Upon termination of this Agreement pursuant to Sections 7(a)
through (e), the Company shall compensate Executive (or, in the event of
Executive's death, his surviving spouse, if any, or his estate) for (x) accrued
but unused vacation time, (y) any base salary earned, but unpaid, for services
rendered to the Company on or prior to the date of termination and (z) amounts
which the Executive is otherwise entitled to receive under the terms of or in
accordance with any plan, policy, practice or program of, or contract or
agreement with the Company (including, without limitation, the plans and
programs made available to Executive pursuant to Section 3(a)(iii)), as in
effect immediately prior to the date of such termination, at or subsequent to
the date of termination without regard to the performance by Executive of
further services or the resolution of any contingency, but subject to any and
all rights, remedies and claims of the Company against Executive.

            (b) Subject to section 8(c) below, if Executive resigns for Good
Reason pursuant to Section 7(g) or his employment with the Company is terminated
without Cause pursuant to Section 7(f), the Company shall thereupon pay
Executive the following amounts and benefits as severance benefits: (i) all
amounts payable pursuant to Section 8(a), and (ii) a lump sum equal to one
year's base salary hereunder plus an amount equal to the most recent annual
bonus, if any, received by Executive pursuant to Section 3(a)(ii), and (iii)
continued coverage for one year under the Company's benefit plans made available
to Executive in accordance with Section 3(a)(iii) (other than the Company's
401(k) and stock purchase plans and any life insurance policy previously
maintained by the Company on the life of Executive) on the same terms as other
similarly situated employees of the Company. If coverage under one or more of
the Company's benefit plans may not be continued because such continuation would
adversely affect the tax-qualified status of such benefit plans, Company may pay
Executive a cash payment that is equal to the value of such continued coverage.

            (c) Notwithstanding anything in this Agreement to the contrary,
Executive shall be eligible to receive a retention bonus, severance payment and
any other benefits set forth in that certain Nextel Partners Inc. Retention and
Severance Plan adopted by the Compensation Committee of the Board of Directors
of the Company on or about January 27, 2005, a copy of which is attached hereto
as Exhibit A and incorporated herein by this reference (the "Retention and
Severance Plan"), in accordance with the terms and conditions set forth in the
Retention and Severance Plan. If Executive qualifies for severance and the
continuation of benefits under the Retention and Severance Plan

<PAGE>

and also qualifies for severance and the continuation of benefits as set forth
in Section 8(b)(ii) and (iii) of this Agreement, Executive shall receive the
severance and benefits under the Retention and Severance Plan and not the
severance and benefits set forth in Section 8(b)(ii) and (iii) of this
Agreement; provided, however, that Executive shall be entitled to receive the
amounts set forth in Section 8(b)(i) of this Agreement and shall be eligible for
any retention bonus under the Retention and Severance Plan in addition to any
other applicable severance and benefits received. The retention bonus, severance
and other benefits which Executive is eligible to receive under the Retention
and Severance Plan are hereby incorporated into and made a part of this
Agreement and may not be modified, altered or amended in any manner that is
adverse to Executive without Executive's prior written consent. Any
modifications or amendments to the Retention and Severance Plan that are
consistent with this Agreement and are favorable to Executive shall be
automatically incorporated into this Agreement and made a part hereof.

            (d) In accordance with the resolutions adopted by the Compensation
Committee of the Board of Directors of the Company on April 15, 2005, the
Company shall make any necessary additional payments (the "Gross-up Payments")
to Executive such that the net amount of the retention and severance payments
and other benefits (whether pursuant to the Retention and Severance Plan, this
Agreement or otherwise) (the "Compensation Payments") received by Executive,
after deduction of any tax imposed by Section 4999 of the Internal Revenue Code
or any successor to Section 4999 on the Compensation Payments and any U.S.
federal, state, and local income or payroll tax imposed on the Gross-up
Payments, but before any deduction for U.S. federal, state and local income or
payroll tax on the Compensation Payments, is equal to the Compensation Payments,
provided that the Company meets or exceeds the operating cash flow objectives
for 2005 adopted at the January 2005 meeting of the Compensation Committee of
the Board of Directors of the Company.

      9. Definitions. As used herein, the following terms shall have the
