     WHEREAS,   Bright   PCS  is  in  the   business   of   providing   wireless
telecommunications services; and

     WHEREAS,  BTS Company is in the  business of  erecting,  owning and leasing
tower facilities for equipment used in providing such services; and

     WHEREAS,  Bright PCS desires to use BTS  Company's  services  to  identify,
evaluate, and acquire sites for such tower facilities; and

     WHEREAS,  BTS  Company  desires  to  construct  a  network  of  such  tower
facilities  within Bright PCS's  service areas in a manner that will  coordinate
with Bright PCS's needs for tower facilities; and

     WHEREAS,  the parties  desire that in most cases a site  identified  by the
procedures set forth herein will result in a tower  facility  constructed by BTS
Company  and  leased to Bright PCS for the  installation  and  operation  of its
equipment; and

     WHEREAS,  this  Agreement  sets forth the  manner in which  Bright PCS will
identify the general  location of potential sites, BTS Company will evaluate and
make recommendations as to specific sites and Bright PCS will lease space on any
such site for the installation  and operation of its equipment  pursuant to this
Agreement.

     NOW,  THEREFORE,  for and in consideration of the mutual promises set forth
herein, the parties hereto agree as follows:

                           1. RELATIONSHIP OF PARTIES

     1.1  INDEPENDENT  CONTRACTOR  RELATIONSHIP.  The  parties  intend  by  this
Agreement to establish an independent contractor relationship. Neither party nor
their employees shall be agents or legal  representatives of the other party for
any purpose.  Neither party shall have the authority to act for, bind, or commit
the other party.  BTS Company and Bright PCS agree that this  Agreement does not
establish or create a relationship of employer-employee,  principal-agent,  or a
franchise, joint venture, or partnership for any purpose whatsoever.

     1.2 CONTRACTS WITH AFFILIATES.  BTS Company may contract with any Affiliate
(as  hereinafter  defined)  of BTS Company to provide  goods or services  beyond
those which its employees would perform, if it deems the same to be necessary or

defined).

     1.3  LANDLORD  AND TENANT  RELATIONSHIP.  BTS  Company and Bright PCS shall
execute  contemporaneously  with the execution of this Agreement,  a Master Site
Agreement  ("MSA") which governs the  relationship of BTS Company,  as landlord,
and Bright PCS, as tenant,  on those BTS Sites which are  accepted by Bright PCS
pursuant  to Section  2.7(b) of this  Agreement.  A copy of the MSA is  attached
hereto as Exhibit "A."

     1.4  EXCLUSIVITY.  During the term of this Agreement,  BTS Company shall be
the exclusive  build-to-suit,  site acquisition,  line and antenna installation,
and construction company for wireless  telecommunications tower sites for Bright
PCS and its Affiliates in Region 1 (as defined in the MSA). For purposes of this
Agreement, "Affiliates" with respect to either party, shall mean companies which
are controlled by that party. For purposes of this Agreement, the word "control"
shall mean the  ownership,  directly  or  indirectly,  or the power to direct or
cause the direction of the management and policies of an entity, or the power to
veto major policy decisions of any such entity, whether through the ownership of
voting securities, by contract or otherwise.  During the term of this Agreement,
Bright PCS shall not engage any third party or Affiliate  directly or indirectly
to  perform  build-to-suit,   site  acquisition,   construction,   or  equipment
installation  services  described in this  Agreement and will not enter into any
discussions  with any  third  party or  Affiliate  concerning,  or  furnish  any
information  relating to such services to any third party or Affiliate,  for the
purpose of  considering,  soliciting  or inducing any offer by such third party.
Notwithstanding  the foregoing,  in the event that Bright PCS and BTS Company do
not agree  upon the  payment  amount  for a CMS Site (as  hereinafter  defined),
Bright PCS shall be entitled to utilize a different  contractor or subcontractor
or its own personnel  for  construction  services.  In the event that Bright PCS
elects to utilize a different  contractor or  subcontractor  as provided herein,
Bright PCS shall first offer BTS Company the right to perform  such  services on
the same terms and conditions as offered by the contractor or subcontractor.

                          II. SITE ACQUISITION SERVICES

     2.1 SITE ACQUISITION SERVICES.

          (a) Bright PCS shall establish small  geographic  areas within which a
     cell site or  transmission  tower  shall be  located,  based on the network
     grid's RF design (a "Search Ring").  For each Search Ring, Bright PCS shall
     provide (i) minimum tower  specifications,  (ii) desired  mounting  height,
     (iii) a description  of the equipment that Bright PCS intends to put on the
     tower, and (iv) any other technical data necessary to permit BTS Company to
     effectively  identify  the  candidate  sites that meet Bright  PCS's needs.
     Bright PCS will provide to BTS Company its system  network  grid,  with the
     established  Search Rings overlaid  thereon.  Bright PCS will, from time to
     time,  assign  Search Rings to BTS Company.  BTS Company  shall provide the
     personnel and facilities which are necessary to locate and lease or license
     existing towers, buildings or other structures by Bright PCS to be used for
     the construction  and installation of Bright PCS's equipment  ("Collocation
     Sites") or  unimproved  real  property  suitable for the  construction  and
     installation of a communications  tower ("Tower") and related facilities by
     BTS Company  ("BTS  Site").  As used  herein,  "Sites"  shall refer to both
     Collocation Sites and BTS Sites,  where  appropriate.  The Site Acquisition


                                       2

     Services are more  particularly  described in and shall be performed by BTS
     Company in accordance  with the scope of work  attached  hereto as Schedule
     "A"  which  is   incorporated  by  reference   herein  ("Site   Acquisition
     Services").  BTS Company shall be entitled to compensation  from Bright PCS
     for the Site Acquisition Services as set forth on Schedule "C".

          (b) Upon its receipt of a Search Ring  designated  hereunder by Bright
     PCS, BTS Company shall promptly,  diligently and professionally perform the
     Site  Acquisition  Services  with respect to such Search Ring.  BTS Company
     shall  perform  the Site  Acquisition  Services  in  accordance  with  this
     Agreement, including, without limitation, the objectives and procedures set
     forth in Schedule "A" ("Objectives and  Procedures").  Provided that Bright
     PCS does not  materially  increase  BTS  Company's  duties  or  impair  BTS
     Company's  rights  hereunder,  Bright PCS shall have the right from time to
     time upon written  notice to BTS Company to adjust,  modify,  or supplement
     the  Objectives and Procedures and the form of documents to be generated or
     provided by BTS Company pursuant thereto.

          (c) Except as  expressly  authorized  in this  Agreement  or otherwise
     expressly  authorized  by Bright PCS in writing,  BTS Company shall provide
     all labor,  equipment,  material and supplies  necessary or  appropriate to
     perform Site Acquisition  Services. In the event that BTS Company elects to
     subcontract any Site Acquisition Services,  BTS Company shall obtain Bright
     PCS's prior written consent to utilize such  subcontractors,  which consent
     shall not be unreasonably conditioned, delayed or withheld.

          (d) During the performance of Site  Acquisition  Services with respect
     to any  designated  Search  Ring,  BTS Company  shall at all times  apprise
     Bright  PCS of any  expressed  opposition,  protest,  litigation  or  other
     efforts, whether by an individual, group, neighborhood association or other
     organization, to restrict, alter or prohibit the construction, installation
     or operation of any structure,  structures or other  facilities that Bright
     PCS or BTS Company proposes to construct or operate on any Site within such
     Search Ring.

     2.2  WITHDRAWAL  OF SITE.  In the event  Bright  PCS  elects to  withdraw a
Collocation  Site at any  time  or a BTS  Site  pursuant  to the  terms  of this
Agreement, Bright PCS shall give BTS Company notice of such withdrawal and shall
pay BTS Company [***] of the milestone  instrument that would be due if the work
currently in progress was completed,  [***] of the reimbursable costs which were
incurred prior to the date on which BTS Company receives notice of the withdrawn
Site,  and [***] of all other amounts due  hereunder  for work  completed on the
Site as of the date BTS Company  receives  Bright  PCS's  withdrawal  notice and
substitute the withdrawn  Site with an  alternative  site within sixty (60) days
("Alternative Site"), if available.  In the event that a withdrawn Site is a BTS
Site,  Bright  PCS  shall  pay BTS  Company  for Site  Acquisition  Services  in
connection with such Site as set forth in Schedule "C" attached hereto.

     2.3 SEARCH RINGS DESIGN. Bright PCS shall have the right at any time in its
sole and absolute  discretion to expand or  reconfigure a previously  designated
Search Ring.  In the event that Bright PCS  redesigns a search ring beyond [***]
miles of an urban or suburban  Site or [***] miles of a rural Site for which BTS
Company has begun but not yet  completed  all Site  Acquisition  Services,  then
Bright  PCS  shall  pay BTS  Company  [***]  for all Site  Acquisition  Services
completed  at the time that the notice of redesign  is received by BTS  Company,
[***] of the  reimbursable  costs which were incurred prior to the date on which
BTS Company receives notice of such  reconfigured  Search Ring, and [***] of the
milestone  installment  that would be due if the work  currently in progress was
completed.  In the event that such Site was a BTS Site, Bright PCS shall pay BTS
Company for such Site Acquisition Services as set forth on Schedule "C". For all
Site Acquisition  Services rendered for the redesigned Search Ring, in the event
that the Site in the redesigned  Search Ring is not a BTS Site, Bright PCS shall
pay BTS Company an additional  [***] of the milestone  installments  due for all
milestone  installments to be performed and [***] of all milestone  installments
to be performed for the first time and [***] of the reimbursable costs which are
incurred.  Bright PCS agrees not to develop  any site within any  redesigned  or
withdrawn  Search  Rings as a tower site and further  agrees not to transfer the
associated Work Product to any third party, including Affiliates.

     2.4 TERM OF SITE ACQUISITION SERVICES AGREEMENT. The term of this Agreement
(the "Site  Acquisition  Term") shall commence on the date of this Agreement and
shall expire on December 31, 2001.

          (a) This Agreement may be terminated as to any particular  Search Ring
     upon written  notice by either party  following the other party's breach of
     an obligation or covenant on such party's part to be performed with respect
     to that Search  Ring,  which  breach is not cured  within  thirty (30) days
     after the breaching party's receipt of written notice;  provided,  however,
     that so long as the defaulting party commenced  appropriate curative action
     within  such thirty (30) day period and  thereafter  diligently  prosecutes
     such cure to  completion  as promptly as possible,  the cure period will be
     extended  until the cure is  completed.  If a party  fails to cure a breach
     within this thirty (30) day period as it may be extended, the party will be
     in default  under this  Agreement  as it applies to the  applicable  Search
     Ring; and

          (b) Neither a termination  nor the expiration of this Agreement  shall
     affect:

               (i) the  term  of the MSA or any  SLA,  as that  term is  defined
          herein,  which has been entered into by the parties  prior to the date
          of termination of this  Agreement,  which shall continue in accordance
          with its terms and conditions;

               (ii) the terms of this  Agreement that apply to any SLA which has
          been entered into by the parties prior to the date of  termination  of
          this Agreement;

               (iii) any duties or obligations  for payment or performance  that
          are or become  owing  hereunder  prior to the  effective  date of such
          termination;

               (iv) the terms of this  Agreement  that apply to any Search  Ring
          which was issued prior to the date of termination  of this  Agreement;
          or



                                       4
<PAGE>
                                        [***] - CONFIDENTIAL TREATMENT REQUESTED


               (v) any other duties or obligations  that  expressly  survive the
          termination or expiration hereof.

          (c) A default regarding one Search Ring shall not constitute a default
     under this Agreement;  however, a default under the greater of [***] Search
     Rings; or [***] or more of the Search Rings which have been issued pursuant
     to this Agreement, shall constitute a default under every Search Ring and a
     default under this  Agreement.  In the event of such a default,  Bright PCS
     shall be entitled to terminate  the services of BTS Company and complete or
     engage a third party to complete BTS Company's  responsibilities under this
     Agreement pursuant to the Plans and Specifications (as hereinafter defined)
     provided by BTS Company.  In such event,  Bright PCS shall convey the Tower
     Facilities  (as  hereinafter  defined) and any site  development  materials
     including ground leases and title,  environmental and geotechnical  reports
     to BTS Company upon completion,  lien free, and BTS Company shall reimburse
     Bright PCS for the reasonable costs of completing its  responsibilities and
     pay Bright PCS the applicable  site  development  fee set forth in the Site
     Development Agreement (as hereinafter defined).

     2.5 GROUND LEASES.  The acquisition of BTS Sites by BTS Company pursuant to
this Agreement  shall be accomplished  using a lease agreement in  substantially
the same form as the  Option and Lease  Agreement  which is  attached  hereto as
Exhibit "B" (hereafter the "Ground Lease").  In no event shall BTS Company agree
to material  modifications  to the  provisions  set forth in paragraph 35 of the
Ground Lease without  Bright PCS's prior written  approval.  The  acquisition of
Collocation   Sites  by  BTS  Company   pursuant  to  this  Agreement  shall  be
accomplished  using a lease  agreement  which  Bright  PCS shall  provide to BTS
Company  or on such other form  which  Bright PCS may,  in its sole  discretion,
approve.

     2.6.  ACCEPTANCE AND REJECTION OF COLLOCATION SITES.  Bright PCS may at any
time  in its  sole  and  absolute  discretion  accept  or  reject  any  proposed
Collocation  Site.  Without limiting the foregoing,  Bright PCS may withdraw its
prior acceptance of a Collocation Site and thereby reject such Collocation Site.
A withdrawal or a rejection by Bright PCS of a Collocation Site shall not affect
its  obligation  for  fees  earned  through  the  date of  termination  for Site
Acquisition Services as more particularly described in Section 2.2.

     2.7 ACCEPTANCE AND REJECTION OF BTS SITES; EXECUTION AND DELIVERY OF SLAS

          (a) A BTS Site  shall be  deemed to be an  accepted  BTS Site from and
     after the date that the Candidate  Site which  corresponds  to the BTS Site
     has been  approved by Bright PCS pursuant to Section 2(a) of Schedule A and
     shall  continue to be deemed an accepted  BTS Site unless and until  Bright
     PCS rejects the BTS Site pursuant to Section 2.7(b) hereof.

          (b)  Bright PCS may at any time prior to the  parties'  execution  and
     delivery  of an SLA  corresponding  thereto,  and in Bright  PCS's sole and
     absolute discretion, reject any BTS Site. In the case of a BTS Site that is
     accepted by Bright PCS, the following shall apply:



                                       5
<PAGE>

               (i)  BTS  Company  shall  continue  the  diligent,  thorough  and
          professional  prosecution of Site Acquisition  Services (including the
          completion of Ground Lease negotiations and required zoning,  land use
          and  permitting   matters)   necessary  for  the   construction  of  a
          communications  tower  and  related  facilities  consistent  with  the
          criteria theretofore identified by Bright PCS;

               (ii) Subject to Section 2.7(b)(iii) below, BTS Company and Bright
          PCS  shall  prepare  and  finalize  the  SLA  (and  exhibits  thereto)
          applicable to such BTS Site;

               (iii) Within thirty (30) days following BTS Company's  receipt of
          all necessary zoning or other land use permits or approvals applicable
          to the  improvements  to be constructed by BTS Company on the BTS Site
          and the completion of Site Acquisition Services in accordance with the
          Objectives and Procedures,  but subject to Section  2.7(b)(iv)  below,
          Bright  PCS  and  BTS  Company  shall  execute  and  deliver  the  SLA
          applicable thereto.  Unless Bright PCS rejects the applicable BTS Site
          within  thirty  (30)  days  following  notice  by BTS  Company  of BTS
          Company's receipt of all necessary zoning or other land use permits or
          approvals applicable to the landlord improvements to be constructed by
          BTS  Company  on the BTS Site  and BTS  Company's  completion  of Site
          Acquisition Services in accordance with the Objectives and Procedures,
          BTS Company shall be  unconditionally  obligated to enter into the SLA
          with  respect  thereto  upon  receipt  of the  foregoing  permits  and
          approvals,  and shall thereafter perform its obligations thereunder in
          accordance  with  the  SLA and  this  Agreement.  Notwithstanding  any
          provision of this Agreement to the contrary,  in the event that Bright
          PCS neither  accepts  nor  rejects the BTS Site within  thirty days as
          provided herein, BTS Company may, at BTS Company's sole option, either
          (1) deem the BTS Site  approved  (in which event BTS Company  shall be
          entitled to compel Bright PCS to execute a SLA with respect to the BTS
          Site) or (2) deem the BTS Site to be denied and make  demand on Bright
          PCS for payment of the fees earned for Site Acquisition Services.

               (iv) Bright PCS may in its sole and absolute  discretion withdraw
          its prior  acceptance of a BTS Site, and thereby reject said BTS Site,
          at any time prior to the BTS Company  parties'  execution and delivery
          of the SLA for such BTS Site.

          (c) In the event of a rejection by Bright PCS of a BTS Site, including
     a rejection after a prior acceptance  thereof as described above in Section
     2.7(b) hereof,  Bright PCS's only obligation for such BTS Site shall be for
     the payment of Site Acquisition  Services  incurred prior to such rejection
     with respect to the Search Ring containing such BTS Site in accordance with
     Section  2.2. In such event,  Bright PCS agrees not to develop the rejected
     BTS Site as a tower site and further  agrees not to transfer the associated
     Work Product to any third party, including Affiliates.



                                       6
<PAGE>

          (d) In the  event of a  rejection  by Bright  PCS of a BTS  Site,  BTS
     Company may elect to forego the  compensation  set forth in Section 2.2 and
     retain the Work  Product.  In such event,  Bright PCS shall have the right,
     but  not  the  obligation,  for a  period  of one (1)  year  following  the
     construction  of a tower on such  Site to enter  into an SLA for such  Site
     pursuant to the MSA as if such Site were  constructed  as an  accepted  BTS
     Site.

          (e) This  Section  2.7 shall not be  deemed to limit or  restrict  any
     rights of  termination  of an SLA as expressly  set forth  therein.  Bright
     PCS's  rights of  rejection  with  respect to a BTS Site  contained in this
     Section  2.7  shall  be in  addition  to,  and  not in  lieu  of,  any  SLA
     termination rights.

          (f) In the event that BTS Company's due diligence  investigation  of a
     BTS Site  reveals  any  defect in such Site  which BTS  Company  reasonably
     believes would materially  adversely affect BTS Company's  multi-tenant use
     or  ownership  of such Site,  BTS Company  shall be entitled to reject such
     Site upon notice to Bright  PCS.  In such event,  Bright PCS shall have the
     right to designate another candidate site as the preferred  candidate.  BTS
     Company shall bear all costs  associated with Site  Acquisition  Activities
     and all costs associated with the due diligence investigation,  zoning, and
     permitting of such Site.

     2.8 CONTINUED  PERFORMANCE  OF SITE  ACQUISITION  SERVICES  FOLLOWING  SITE
ACCEPTANCE OR REJECTION.  Unless  otherwise  notified by Bright PCS, BTS Company
shall:

          (a) Following Bright PCS's acceptance of any Site, continue to perform
     Site Acquisition  Services with respect to such accepted Site in accordance
     with this  Agreement,  including,  without  limitation,  the Objectives and
     Procedures; and

          (b)  Following  Bright  PCS's  rejection  of  any  Site  (including  a
     rejection after Bright PCS's prior acceptance thereof), continue to perform
     Site  Acquisition  Services  with  respect  to the Search  Ring  pertaining
     thereto (including a modified Search Ring as described above in Section 2.3
     hereof) in  accordance  with the terms and  conditions  of this  Agreement,
     including, without limitation, the Objectives and Procedures.

     2.9 NO CONFLICTING OBLIGATIONS.

          (a)  Neither  BTS  Company  nor any  Affiliate  of BTS  Company  shall
     hereafter  during  the Site  Acquisition  Term  enter  into any  agreement,
     contract  or other  arrangement  with any  Competitor  other  than  Horizon
     Personal  Communications  Services,  Inc. For  purposes of this  Agreement,
     "Competitor"  shall mean an entity whose business includes the provision of
     wireless  telecommunications  services to the public  pursuant to which BTS
     Company or any  Affiliate of BTS Company  agrees to provide to or on behalf
     of such  Competitor site  acquisition  services that: (i) may result in the
     leasing  (or  other  acquisition)  of real  property  and the  construction
     thereon by BTS  Company  or such  Affiliate  of a  wireless  communications


                                       7
<PAGE>

     facility designed to meet such Competitor's  specifications and (ii) affect
     or may affect any real property  located  within a Search Ring. BTS Company
     shall provide to Bright PCS during the Site  Acquisition Term BTS Company's
     primary duty of loyalty and  professionalism  in the performance within the
     geographic area of Site Acquisition  Services hereunder.  BTS Company shall
     not perform, or undertake to perform, any services that would conflict with
     BTS Company's loyal,  professional  and diligent  performance of its duties
     hereunder.  The foregoing provisions of this Section 2.9(a) shall not apply
     if BTS  Company  notifies  Bright PCS of a  preexisting  conflict  upon BTS
     Company's  receipt  of a Search  Ring,  nor will it apply to a Search  Ring
     after BTS  Company  has  completed  construction  of a BTS Site within such
     Search Ring.

          (b) In the course of performing Site Acquisition Services or otherwise
     in conducting its activities under or with respect to this Agreement or any
     SLA,  BTS  Company  shall  not  publish  or  distribute  any  materials  or
     documentation  using Bright PCS's name without  Bright PCS's  express prior
     written permission  specifically  relating to such use; provided,  however,
     that BTS  Company  shall be  entitled  to utilize  Bright  PCS's name where
     reasonably necessary to facilitate zoning and other governmental approvals.

     2.10  COMPLIANCE  WITH LAWS.  BTS Company  represents  and warrants that it
shall:  (a) comply  with all  federal,  state and local  laws,  regulations  and
ordinances with respect to its performance of the Site Acquisition Services; (b)
file all reports  relating to the Site  Acquisition  Services and required under
applicable law (including,  without limitation, tax returns); (c) pay all filing
fees and federal,  state and local taxes applicable to BTS Company's business as
the same shall become due; and (d) pay all amounts  required under local,  state
and federal workers' compensation,  disability benefit,  unemployment insurance,
and other  employee  benefit laws and  regulations  when due. BTS Company  shall
provide Bright PCS with such documents and other supporting  materials as Bright
PCS may reasonably request to evidence BTS Company's continuing  compliance with
this Section 2.10.

     2.11  INSURANCE.  BTS Company and Bright PCS shall each maintain in effect,
without interruption, on an annual basis, during the term of this Agreement, the
following insurance policies:

          (a) Commercial  General Liability (Bodily Injury and Property Damage).
     Insurance  coverage with  endorsement  evidencing  coverage for contractual
     liability. The limits of this insurance shall not be less than:

               (i) Each Occurrence Limit $1,000,000

               (ii) General Aggregate Limit $2,000,000

     3.1 CONSTRUCTION AND CONSTRUCTION MANAGEMENT. BTS Company shall perform the
services  set forth on  Schedule  "B"  attached  hereto  (all of which  shall be
hereinafter referred to collectively as the "Construction  Management Services")
for Bright PCS, for each site chosen  within each of the Search Rings  assigned.
All sites for which BTS Company will perform  Construction  Management  Services
shall hereinafter be referred to as the "CMS Sites."

     3.2 PROGRAM MANAGEMENT SERVICES.  In connection with, and as a tracking and
indexing  mechanism  for its  provision  of Site  Acquisition  and  Construction
Management  Services  pursuant to this  Agreement,  BTS Company  shall  develop,
implement and maintain a deployment  plan which tracks all  activities and costs
associated with the performance of Site  Acquisition  Services and  Construction
Management Services for each Site in accordance with the following procedures:

          (a) BTS  Company  shall  develop  and  implement  a quality  assurance

     standards as may be established from time to time by Sprint Spectrum, L.P.

          (b) BTS Company shall develop and  implement  comprehensive  reporting
     mechanisms so that detailed site progress is tracked on a weekly basis, and

                                       10
<PAGE>

          (c) BTS Company  shall develop and  implement a  comprehensive  filing
     system that ensures that all relevant  site  information  is organized  and
     available.  BTS  Company  shall  seek  to  use  electronic  means  whenever
     available.  BTS Company  shall ensure the  physical  security of the filing
     system.

          (d) BTS Company  shall manage and  coordinate  interaction  among site
     acquisition construction, management, and the A&E firm.

          (e) BTS Company shall manage and coordinate  interactions  between the

systems,  power and telephone  connections to a central demarcation point within
the tower compound,  and a concrete  equipment pad as specified by site diagrams
for Bright PCS's equipment and battery back-up ("Tower Facilities"). BTS Company
shall  prepare  and  deliver  to Bright  PCS for its  approval  three  copies of
prototype,    standard   plans   ("Plans")   and   construction   specifications
("Specifications") for the construction of prototype Tower Facilities. The Plans

objections  thereto.  Bright PCS shall approve the Plans and  Specifications  if
they meet the minimum specifications set forth by Bright PCS in its Search Ring;
provided,  however,  that  Bright PCS shall not be required to approve the Plans
and Specifications if BTS Company's Plans and  Specifications  contemplate tower
height or loading in excess of what was contemplated in Bright PCS's Search Ring
minimum  specifications,  and such excess  would  cause a material  delay in BTS
Company  obtaining  governmental  approvals with respect to the applicable Site,
and such delay would materially delay Bright PCS's anticipated installation date

     4.2 CHANGE  ORDERS.  Bright  PCS shall  have the right to issue  reasonable

the Tower Facilities are to be constructed. BTS Company shall have no obligation
to commence construction of the Tower Facility at a Site unless and until an SLA
has been  properly  executed by Bright PCS for that Site.  In the event that BTS
Company  reasonably  anticipates  that the  construction  of a particular  Tower
Facility at a Site cannot be completed within sixty (60) days after execution of
an SLA,  BTS Company  and Bright PCS shall act  reasonably  in agreeing  upon an
alternate number of days which will be required to complete construction. In the
event that BTS Company fails to complete the  construction of any Tower Facility
within  thirty  (30)  days of the date on which  such Site was  scheduled  to be
completed (as such scheduled  completion date may have been extended pursuant to
the  previous  sentence),  BTS  Company  shall pay to Bright  PCS as  liquidated
damages the sum of [***] for each day on which the Tower  Facility  has not been


                                       12

completed after the scheduled completion date (as such scheduled completion date
may have been  extended  pursuant to the previous  sentence)  unless  Bright PCS
elects to terminate this Agreement pursuant to Section 2.4(c) in which event the
liquidated  damages  provided for herein shall cease to accrue on the  effective
date of such  termination.  Except as provided in Section 2.4(c)  herein,  these
liquidated  damages  shall be Bright  PCS's sole  remedy,  in the event that BTS
Company fails to meet such construction deadline.

     4.6. MANNER OF CONSTRUCTION.  BTS Company  represents,  warrants and agrees
that the Tower Facilities shall be constructed in a good and workmanlike  manner
and at a minimum in accordance with Bright PCS's minimum  specifications and all

and that such  construction  will be of good quality in accordance with industry
standards, free from faults and patent defects. The warranties contained in this
Section 4.6 shall run for a period of six (6) months  from the SLA  Commencement
Date, as defined in the MSA.

     4.7. NO LIENS.  BTS  Company  shall keep the Tower  Facilities  free of all
liens  and  claims  arising  out  of  or  related  to  the  performance  of  the
construction,  all liens and claims of any contractor,  subcontractor,  laborer,
mechanic or materialman for labor  performed or material  finished in connection
with the performance of the construction. In the event any such lien is recorded
against  the Site,  the BTS  Company  shall,  within  thirty (30) days after its
receipt of notice that such a lien has been recorded,  either (a) have such lien
released of record,  or (b) deliver to Bright PCS a bond,  in form,  content and

Company a list of items ("Punch List") that Bright PCS deems necessary, that BTS
Company complete or correct in order for the Tower Facilities to be completed in
accordance with Bright PCS's minimum  specifications  for the applicable  Search
Ring.  The Tower  Facilities  shall be deemed  accepted by Bright PCS if a Punch
List is not received by BTS Company  within three (3) business  days of the date
of Notice of  Completion.  In the event that Bright PCS delivers a Punch List to
BTS  Company,  the  notification  process  set  forth in this  section  shall be

                             VII. DISPUTE RESOLUTION

     7.1 ARBITRATION  PROCEDURE.  If the parties in this Agreement are unable to
resolve any dispute arising out of or relating to this Agreement,  either party,
may refer such  dispute for  resolution  by final and binding  arbitration.  The
party  submitting  a dispute to  arbitration  shall give notice  thereof to each
other party to such dispute and to the  President  of the  American  Arbitration
Association,  who shall  select an  arbitrator  (the  "Arbitrator")  who (i) has
expertise and at least five years'  experience in matters directly involved with
the type of services to be performed under this Agreement in the geographic area
in which the  obligations  hereunder are to be performed,  (ii) certifies to all
parties  that  he/she is  independent  of the parties to the dispute and will be
able to render an impartial decision,  and (iii) agrees to proceed in accordance
with the applicable provisions of this Section 7.1.

     The Arbitrator shall hold one or more hearings to begin within fifteen (15)
days of his/her  selection,  shall furnish a written decision within  forty-five
(45) days of his/her selection,  and shall provide an opinion  demonstrating the
basis for such decision.  The Arbitrator may also attempt to mediate the dispute
between parties if requested to do so by both of the parties.

     The  parties  hereto  agree  to  exchange  promptly  any and  all  relevant
documentation as the Arbitrator may order. All arbitration proceedings hereunder
shall be  conducted  in private,  and each party  hereby  agrees to maintain the
confidentiality  of the enforcement of the award.  All  arbitration  hearings or
mediation sessions are to be held in the Chillicothe, Ohio area unless otherwise
agreed  by the  parties,  and  arbitration  hearings  need not be  conducted  in
accordance with formal rules of evidence.



                                       17

     The Arbitrator may determine the procedure for hearings which may, but need
not,  include  (a) direct  testimony  of  witnesses;  (b)  cross-examination  of
witnesses; (c) submission of sworn statement or affidavits; (d) consideration of
relevant documents;  and (e) consideration of other matters which the Arbitrator
considers to be helpful in making his/her decision.

     7.2  COST  OF  ARBITRATION.   The  Arbitrator's  fees  and  other  expenses
associated with  arbitration  shall be borne equally by the parties,  unless the
Arbitrator finds that the position of one party is frivolous or unreasonable, in
which case the  Arbitrator  may require the offending  party to pay all fees and
expenses (or some disproportionate amount) associated with the arbitration.

     7.3 CONTINUED  PERFORMANCE.  At all times during the course of  arbitration
proceedings,  the  parties  shall  continue  in  good  faith  to  perform  their
respective obligations under this Agreement,  to the extent such obligations are
not in dispute. If a disputed issue is impeding continued  performance by either
party,  the  Arbitrator  may adopt an expected  schedule  upon request of either
party.  Notwithstanding the foregoing,  should BTS Company not be paid in timely
fashion  for any Site  Acquisition  Service  not  disputed  and not  subject  to
arbitration  proceedings,  BTS Company may suspend its  performance of such Site
Acquisition Service.

     7.4 AWARD  ENFORCEMENT.  The arbitrator  may award monetary  damages and/or
make a  binding  order,  and the  parties  hereby  agree  that an  award  of the
Arbitrator  hereunder  may be  enforced  by either  party in the  United  States
District Court which has jurisdiction over matters arising in Chillicothe, Ohio.

     7.5 THIRD PARTY  GUARANTEES AND WARRANTIES.  If any of the Site Acquisition

materials or the  procurement  of services,  BTS Company  shall make  reasonable
efforts to obtain from all vendors and  subcontractors  commercially  reasonable
guarantees  and  Warranties  with  respect  to  such  equipment,  materials  and
services.  BTS Company's  liability with respect to such equipment and materials
obtained  from  vendors  or  services  from  subcontractors  shall be limited to
procuring  guarantees  from such vendors or  subcontractors  and  rendering  all
reasonable assistance to Bright PCS as part of the Site Acquisition Services for
the purpose of enforcing the same.

     7.6 PERMITS.  BTS Company  shall  (without  additional  compensation)  keep
current all governmental  permits (other than Building  Permits),  certificates,
and  licenses  (including  professional  licenses)  required by law to be in BTS
Company's name necessary to perform the Site Acquisition Services.

     7.7  PUBLICITY.  Neither  party  shall make news  releases  or issue  other
advertising  pertaining  to the  Site  Acquisition  Services  or this  Agreement
without prior written approval of the other party; provided,  however, that both
parties agree to either approve or deny such news release or advertising  within
two (2) business days of the request for approval  from the other party.  In the
event a party fails to either approve or deny such news release or advertisement
