Spectrum Sharing and Microwave Relocation Services
--------------------------------------------------

Entel, utilizing the Comsearch IQ Clear spectrum sharing tool, procured and
provided by Entel, will supply to Triton all labor, services, resources, and
consultation necessary to perform the spectrum sharing study and analysis, drive
test frequency selection, and prior coordination notices described below
("Spectrum Sharing Services"). Entel will also provide Triton with the Microwave
Relocation Services described below.

1. Spectrum Sharing Study and Analysis

Entel will perform spectrum-sharing studies, as required by Triton, for the
selected frequency, in each assigned BTA. The studies will initially be
based on the generic traffic cell based design, which will be modified
subsequently to include RF design information provided by Triton. Entel
will identify all paths that could be affected by Triton's proposed PCS
systems, based on FCC guidelines on interference avoidance. Entel will
perform multiple interference studies for each assigned frequency and BTA,
as required, over the course of the design and buildout phases.

2. Drive Test Frequency Selection

On a continuous basis as frequencies are assigned, Entel will complete the
spectrum sharing study and analysis and provide Triton with the required
drive test frequencies for the assigned BTS locations (if a non-interfering
frequency is available).

3. Prior Coordination Notices

Entel will prepare Prior Coordination Notices (PCN(s)), mail PCNs to
incumbents and clearinghouses, and coordinate responses and objections to
PCNs, as required. Typically one PCN mailing will be required for each BTA,
unless considerable RF engineering design changes occur later in the pre-
launch phase. As a result of RF design changes, additional PCN(s) will be
performed as required.

4. Microwave Relocation Services

Phased Delivery of Services
---------------------------

Entel shall provide Triton with microwave relocation services (the

and will perform the following steps as required to complete assessment of
interfering paths/incumbents as identified in the spectrum sharing study
and analysis.

A. Service Description
-------------------

1. Review and Catalog Path Data. Review information from the
----------------------------
spectrum sharing study and analysis on a per market and per
incumbent basis for both co-channel and adjacent channel paths.
Information such as number of links, equipment and modulation
type, capacity, site names and locations for each path will be
logged for use during negotiations and relocation

program management.

3. Path Prioritization. Entel will develop technical parameters for
-------------------
the interfering co and adjacent channel paths to establish
negotiation and relocation strategies and path priorities.

4. Review of Incumbent Data. Entel will review incumbent system data
------------------------
on a per link basis and compare the information against FCC
database information to determine whether the incumbent is
operating on a primary status with a current license.

5. Path Status Verification and Initial Incumbent Assessment. Entel
---------------------------------------------------------
will contact each incumbent to confirm database information,
verify path status, i.e. active, negotiated, or decommissioned.
If the incumbent has not entered into an agreement with another
PCS licensee, then Entel will assess the incumbent's willingness
to negotiate, identify strategic information, and discuss
preliminary relocation options.

6. Assessment of Previously Negotiated Paths. Entel will attempt to
-----------------------------------------
obtain the terms and status of each relocation agreement entered
into between an incumbent and other PCS licensee(s). Entel will
attempt to obtain a copy of the agreement, provided that it is
not protected by a non-disclosure agreement. Entel will determine
whether the dates agreed upon in the relocation agreement meet
Triton's requirements.

7. Estimate Comparable Relocation Costs. Estimate relocation costs
------------------------------------
on a per incumbent and per market basis for paths that are
determined to be active or co-channel paths that have been
negotiated and/or relocated. Information such as system type and
architecture, number of links required to be relocated, tower
heights and typical system usage will be used to develop the cost
estimates.

8. Route Mapping. Develop route maps on a per incumbent and per
-------------
market basis delineating co-channel and adjacent channel active
paths.

B. Deliverables
------------

Entel will provide to Triton a written report containing the following
information:

and negotiation contact for each incumbent and send an
introductory mailing packet containing general information on
microwave relocation and specific information about Triton and
its proposed course of action.

2. Negotiation Parameters. Entel will work with Triton to develop
----------------------
negotiation parameters. These parameters should be established
prior to the commencement of negotiations so that settlements may
be negotiated expeditiously.

3. Development of Negotiation Strategies. Entel will work with
-------------------------------------
Triton to develop optimal negotiation strategies for each
incumbent and market. These strategies will be based upon the
size and location of each incumbent's network, considering
whether the incumbent is present in multiple Triton markets,
Triton's priorities and its willingness to provide various
relocation alternatives.

4. Initiate Negotiations. Entel will negotiate with incumbent to
---------------------
reach an agreement that conforms to Triton's relocation schedule
and cost parameters.

5. Additional Negotiation and Finalization of Agreement for Amended
----------------------------------------------------------------
Relocation Dates. If a path has been negotiated by another PCS
----------------
licensee, but the relocation date(s) are unacceptable to Triton,
then Entel will initiate negotiations with the incumbent, other
PCS licensee(s) or both to alter the unacceptable relocation
dates and bring them into conformity with Triton's relocation
priorities.

6. Negotiation Strategy. Entel will re-assess negotiation parameters
--------------------
and strategies as required based on discussions with incumbents,
additional information obtained from incumbent meeting, and any
modifications to Triton's deployment schedule.

Comparable Cost Appraisal and Cost-Sharing Negotiations
-------------------------------------------------------
Scope of Services
-----------------

Phased Delivery of Services
---------------------------

WFI will supply to Customer all labor, services, resources, and consultation
necessary to perform the 2 GHz microwave cost-sharing negotiation services
described more particularly below. These services are in regard to negotiating
on behalf of the Customer with the PCS Relocator seeking reimbursement from the
Customer through a designated FCC Clearinghouse. The goal of these services is
to reduce the cost-sharing reimbursement amount paid by the Customer to the PCS
Relocator.

The Services shall be delivered to Customer in two phases:

Phase I: Comparable System Cost Appraisal
--------

Phase II: Cost-Sharing Negotiations
--------

The steps required for each of the three phases are described in detail
below.

Phase I: Comparable System Cost Appraisal
-----------------------------------------

WFI will utilize FCC database information and information obtained from
microwave incumbents as required to complete an appraisal of the cost associated
with the replacement of a relocated co-channel path that is subject to cost-
sharing reimbursement as per the FCC's cost-sharing rules.

A. Service Description
-------------------

1. Review of FCC Data. WFI will review system data for each link
------------------
assigned as included in the FCC database prior to the relocation
of the path. WFI will reference this data in the relocation cost
appraisal.

2. Incumbent Contact and Replacement System Verification. WFI will
-----------------------------------------------------
contact each incumbent and attempt to confirm database
information and request information concerning the actual
replacement system installed by the incumbent or the PCS
Relocator. WFI will utilize such information in determining the
appropriate allowable reimbursement as required by the FCC's
cost-sharing rules.

3. Replacement System Design and Cost Appraisal. WFI will complete
---------------------------------------------
the design of a microwave replacement system for each assigned
link. This design will be based on a replacement system that is
comparable to the original 2 GHz link, as defined by the FCC's
cost-sharing rules. Information such as system type and
architecture, tower heights, and typical system usage will be
used to develop these cost estimates. Additionally, if available,
WFI will utilize actual replacement system data, as provided by
incumbents, in order to determine what premiums the PCS Relocator
provided to the microwave incumbent.

B. Deliverables
------------

WFI will provide a written report to Customer containing the following
information:

1. Copies of FCC licenses for actual replacement systems, if available;

2. System data (antenna types/sizes, radio manufacture/model, antenna
heights, etc.) for each 2 GHz link subject to cost-sharing;

3. Detailed comparable replacement system design, and;

4. Comparable system replacement cost documentation.

Phase II: Cost-Sharing Negotiations and Final Cost-Sharing Contract Execution
------------------------------------------------------------------------------

A. Service Description
-------------------

A step-by-step outline of the negotiation and information-gathering
efforts to be performed by WFI in this phase is as follows:

1. Introductory Mailing. WFI will identify the proper technical and
--------------------
negotiation contact for each PCS Relocator and send an
introductory mailing packet containing general information on
microwave relocation and specific information about Customer and
its proposed course of action.

2. Negotiation Parameters. WFI will work with Customer to develop
----------------------
negotiation parameters. These parameters should be established
prior to the commencement of negotiations so that settlements may
be negotiated expeditiously.

3. Development of Negotiation Strategies. WFI will work with
-------------------------------------
Customer to develop optimal negotiation strategies for each PCS
Relocator. These strategies will be based upon the reimbursement
amount requested by the PCS Relocator, the estimated cost of
comparable facilities, and the architecture and cost of the
actual replacement system, if available.

4. Initiate Negotiations. WFI will negotiate with the PCS Relocator
---------------------
to obtain an optimal cost-sharing settlement and agreement that
are acceptable to the Customer.

5. Negotiation Strategy. WFI will re-assess negotiation parameters
--------------------
and strategies as required, based on discussions with the PCS
Relocator(s), and additional information obtained from incumbents
and/or the PCS Relocator(s).

6. Contract Templates. If Customer requires such contact, WFI shall
------------------
develop and provide a cost-sharing contract template for the
Customer's review. Customer's inside counsel shall review and
modify the contract template as required.

7. Finalize Cost-Sharing Terms. WFI will provide the proposed
---------------------------
business terms to Customer for approval.

8. Finalize Cost-Sharing Agreement. Once Customer has approved the
-------------------------------
business terms, WFI shall work with Customer's counsel to
facilitate the negotiation and

Proprietary and Confidential
Page 2 of 4

execution of the final cost-sharing agreement between Customer
and the PCS Relocator.

B. Deliverables
------------

WFI will provide Customer with the following deliverables:

1. Signed cost-sharing offer letter;

2. Executed contract between PCS Relocator and Customer, if required;

3. Copies of any correspondence that Customer may request;

Additionally, WFI will submit periodic reports to Customer, detailing the status
of each negotiation and summarizing the information obtained on each path
assigned for negotiation.
