ITEM 1.  BUSINESS

THE COMPANY

  The Company intends to become a leading provider of wireless broadband
personal communications services (commonly referred to as PCS) in the
southeastern United States. The Company was established by Michael Kalogris,
Steven Skinner and other former executives of Horizon Cellular Group, along with
various equity investors, with the intent to develop and operate a leading PCS
network in the Southeast. In October 1997, the Company entered into a joint
venture agreement with AT&T PCS, a wholly-owned subsidiary of AT&T Corp.
(together with affiliates "AT&T"), whereby the Company will be the exclusive pr
ovider of wireless mobility services under the AT&T consumer brand name in a
contiguous area covering approximately 11 million Pops (each person in a defined
market area) in the southeastern United States the ("Licensed Area"). AT&T PCS
contributed certain PCS licenses to the Company covering the Licensed Area in
exchange for an equity interest in the Company. Additionally, the Company is a
party to agreements with AT&T that, among other things, allow the Company to
benefit from AT&T's nationwide wireless footprint and promotional and marketing
efforts and provide the Company with favorable roaming and long distance rates
for services on AT&T's wireless and long distance networks. See "Certain
Relationships and Related Transactions--The AT&T Agreements." The PCS Licenses
authorize the Company to provide PCS services to such major population and
business centers as Charleston, SC, Columbia, SC, Greenville/Spartanburg, SC,
Richmond, VA and Augusta, GA, as well as major destination resorts such as
Myrtle Beach, SC, Hilton Head, SC and Kiawah Island, SC. The Company commenced
commercial operations in the first quarter of 1999 in an initial area covering
approximately 40% of the Pops in the Licensed Area (the "Initial
Configuration").

  The Company believes the Licensed Area has outstanding demographic
characteristics, including strong population growth and favorable population
density and traffic patterns. According to Paul Kagan Associates, Inc., from
1995 to 2000, population growth in the Company's markets is expected to be
nearly double the national average. Additionally, the population density in the
Company's markets is 57% above the national average, and traffic density in the
Company's markets (measured by daily car miles per interstate highway miles) is
7% above the national average. See "--Summary Market Data." The Company believes
that its Licensed Area, together with AT&T's recently launched wireless systems
located in the adjacent cities of Washington, DC, Charlotte, NC and, Atlanta,
GA, creates a large, contiguous area which provides numerous cost and other
synergistic benefits.

  The Company intends to offer customers affordable, reliable, high-quality
mobile telecommunications services. Specific service offerings will include
single number service and advanced features such as call screening and caller
ID. As the market for wireless telecommunications services and the Company's
technological capabilities continue to develop, the Company expects to offer
additional wireless applications such as high-speed data transmission to and
from computers, "wireless office," advanced paging, facsimile and Internet
access services.

  The Company has chosen to build its PCS network using Time Division Multiple
Access ("TDMA") technology based upon the IS-136 standard ("TDMA/IS-136") which
is the technology utilized by AT&T's nationwide wireless network, thus allowing
the Company's network to be compatible with AT&T's and other TDMA/IS-136
networks immediately upon launch of operations. TDMA/IS-136, among other things,
allows service providers to offer enhanced integrated services not currently
offered by traditional analog cellular providers, including integrated
voicemail, custom-calling and short-messaging. Currently three of the top four
wireless telecommunications companies in the U.S., based on current customers,
utilize TDMA/IS-136 technology. 

  On June 30, 1998, the Company acquired an existing cellular system which
serves Myrtle Beach, SC and the surrounding area, from Vanguard Cellular System
of South Carolina, Inc. for a purchase price of approximately $164.5 million.
The Company believes it will seamlessly integrate the Myrtle Beach system, which
uses digital TDMA/IS-136 cellular technology, into its planned PCS network as
part of the Initial Configuration. Since the Myrtle Beach system is within the
Licensed Area, it operates under the AT&T agreements. The Company believes that
the Myrtle Beach acquisition has (i) provided the Company with a system that
currently generates positive cash flow, (ii) accelerated the ability of the
Company to capture roaming traffic generated by Myrtle Beach's highly transitory
population, (iii) accelerated the Company's time-to-market in South Carolina and
(iv) rendered a PCS build-out in the Myrtle Beach region unnecessary.

                                       1

  On December 31, 1998, the Company acquired from AT&T (i) an FCC license to use
20 MHz of authorized frequencies to provide broadband PCS services throughout
the entirety of the Norfolk, Virginia BTA and (ii) certain assets of AT&T PCS
used in the operation of the PCS system in such BTA for an aggregate purchase
price of $111 million. The build-out of the network relating to the Norfolk
Acquisition, including the installation of a switch, has been substantially
completed and the Norfolk BTA commenced commercial operations in the first
quarter of 1999. With the Norfolk Acquisition, coverage within the Company's
contiguous footprint totals approximately 13 million Pops.

  In addition to the contribution by AT&T of the PCS Licenses, the Company has
raised $140 million of irrevocable equity commitments payable over a three-year
period, $80 million of which has been received by the Company as of, March 26,
1999, from, or from entities managed by, Chase Capital Partners, J.P. Morgan
Investment Corporation, Desai Capital Management Incorporated, Toronto Dominion
Capital (USA), Inc., First Union Capital Partners, Inc. and Duff Ackerman
Goodrich & Assoc., L.P. See "Certain Relationships and Related Transactions--The
Securities Purchase Agreement." The Company has also received from the cash
equity investors (i) an additional $35 million in connection with the Myrtle
Beach Acquisition and (ii) approximately $16.5 million in connection with the
Norfolk Acquisition.

STRATEGIC ALLIANCE WITH AT&T

  AT&T holds FCC licenses to provide wireless telecommunications service in
areas covering 96% of the U.S. population. In order to effectively and rapidly
construct its PCS markets and commence offering wireless services, AT&T has
focused on building out selected cities within its coverage area, while entering
into agreements with certain independent wireless operators, such as the
Company, to build out and operate the remainder of its PCS markets. AT&T
contributed the PCS licenses, covering 20 MHz of spectrum in the Licensed Area,
in exchange for an equity interest in the Company and certain other rights
including preemptive rights and the right to appoint one board member. AT&T has
retained 10 MHz of spectrum in the Licensed Area for use as a non-mobile
wireless provider. The terms of the joint venture between the Company and AT&T,
including those governing the 10 MHz of spectrum retained by AT&T, are set forth
in the AT&T agreements described below. See "Certain Relationships and Related
Transactions--The AT&T Agreements."

  The Company believes its alliance with AT&T will enable the Company to benefit
from AT&T's brand name recognition and marketing efforts and provides numerous
other strategic advantages, including the following:

     LICENSE RIGHTS. The Company will market its PCS services as "Member, AT&T
  Wireless Network" and will use the globally recognized AT&T logo.

     COMPANY EXCLUSIVITY. The Company will be AT&T's exclusive provider of
  wireless mobility services for people residing within the Licensed Area.

     AT&T EXCLUSIVITY. The Company will use AT&T as its provider of
  telecommunications services, other than wireless mobility, for its ancillary
  or bundled services, including long distance and, where applicable, local
  service to the Company.

     ROAMING. AT&T's and the Company's customers who own dual-band/dual-mode
  phones will roam on each other's mobile wireless systems. 

     PRODUCTS AND SERVICES. The Company expects to continue to benefit from AT&T
  related discounts on such products and services as handsets, infrastructure
  equipment and billing services. For example, the Company has entered into an
  agreement with Nokia to supply mobile telephone equipment, software and
  services at the discounted prices set for AT&T affiliates.

     RESALE BY AT&T. The Company's network will be utilized by AT&T to provide
  the Company's service to accounts that reside in the Licensed Area. See
  "Certain Relationships and Related Transactions--The Stockholders' Agreement--
  Exclusivity."

BUSINESS STRATEGY

     The Company intends to become a leading provider of wireless broadband
   communications services in its markets. To achieve its objective, the Company
   will pursue the following business strategies:

     LEVERAGE RELATIONSHIP WITH AT&T.   The Company intends to capitalize on the
  marketing opportunities derived from its relationship with AT&T, including (i)
  co-branding with the AT&T logo, (ii) nationwide coverage, (iii) an expansive
  home calling area and (iv) bundling of AT&T telecommunications products and
  service offerings. The Company believes its affiliation with AT&T will also
  yield the following benefits: (a) favorable vendor contracts, (b) long-term
  roaming arrangements with prescribed pricing, including preferred carrier
  status for AT&T-affiliated roaming traffic, and (c) availability of AT&T's
  Network Operating Centers and customer service centers.

     EXECUTE INTEGRATED MARKETING PLAN.   The Company intends to adopt a
  marketing approach that leverages AT&T's nationwide presence and brand name.
  The Company expects to capitalize on its regional focus and its ability, as a
  small, entrepreneurial company, to respond quickly and creatively to changing
  customer needs. In all of its marketing efforts, the Company intends to
  emphasize the improved quality, enhanced features and favorable pricing of its
  PCS system. Its marketing strategy has been designed to increase overall
  wireless communications penetration with an emphasis on mass marketing
  concepts designed to appeal to a broad demographic base.

     CAPITALIZE ON EXTENSIVE TERRITORIAL REACH.   The Licensed Area covers a
  significant percentage of the population of Virginia, virtually all of South
  Carolina, the Augusta region of northeast Georgia and large sections of the
  eastern and western portions of North Carolina. The Company believes that it
  will have an advantage over its competitors, which have less extensive and/or
  non-contiguous coverage by offering regional and state-wide PCS services using
  100% of its own network facilities. Thus, the Company will not need to use a
  third party long-distance carrier, and will therefore be able to complete
  almost any call, within its region, without incurring roaming charges. The
  Company has designed its network to minimize its interconnect expenses and
  reduce infrastructure costs. In addition, the Company operates its entire
  system utilizing only two regional offices, thereby reducing its general and
  administrative expenses.

     PROVIDE SUPERIOR CUSTOMER SERVICE. The Company's strategy is predicated on
  building strong, enduring relationships with customers. The Company is
  developing an organization in which each employee views his or her function in
  terms of the impact on the customer. In support of this strategy, the Company
  has developed a compensation plan tied to the attainment of customer quotas
  and customer retention rates. Furthermore, the Company intends to effectively
  manage its customer relationships through the use of sophisticated information
  systems that best meet the evolving needs of individual customers.

     DEPLOY STATE-OF-THE-ART TECHNOLOGY.   The Company's choice of TDMA
  technology utilizing the IS-136 platform provides the Company with the
  opportunity to capitalize on certain advantages, such as higher voice quality,
  greater security and enhanced features, relative to analog cellular service
  providers. This technology also provides for more powerful error correction,
  less susceptibility to fading and reduced interference (which results in fewer
  dropped calls) and increased customer capacity relative to a typical analog
  system. In addition, the TDMA dual-band/dual-mode handsets provide operating
  capability in both digital mode at 1900 MHz and 800 MHz and analog mode at 800
  MHz, thereby increasing the customer's roaming capabilities. Furthermore, TDMA
  utilizes a hierarchical cell structure that allows for cost-effective capacity
  enhancement and greater customization of calling plans.

     EXECUTE HIGH QUALITY BUILD-OUT PLAN.   The Company plans to construct a
  state-of-the-art, high quality network. The Company's radio frequency design
  has a high density of cell sites which, together with the use of digital
  technology, will allow the Company's system to handle higher traffic demand
  than cellular operators, thereby allowing the Company to offer lower per-
  minute rates. The Company's network design will also allow extensive use of
  micro- and mini-cell sites to service expensive, difficult to reach locations
  and coverage gaps within the Company's wireless network.

                                       3

POTENTIAL EXCHANGE   

On March 24, 1998, the Company entered into a non-binding letter of intent
related to certain transactions, including the potential acquisition of 1.9
million additional net incremental Pops, and the exchange of the Hagarstown, MD
and Cumberland, MD BTAs. The agreement has been modified to only include the
exchange of 512,000 Pops located in the Hagerstown, MD and Cumberland, MD BTAs
for 517,000 Pops located in certian countries in Savannah, GA and Athens, GA
BTAs, all of which are contiguous to the Company's existing service area. Due to
the difference in value per Pop of the BTAs exchanged, consideration of
approximately $9.7 million, all of which is expected to be represented by non-
cash equity interests in Triton PCS Holdings Company, Inc. (Holdings) will be
issued to AT&T. The transaction is subject to execution of a definitive exchange
agreement and closing conditions typical in transactions of this nature. If the
transaction is consummated, Holdings intends to contribute the Savannah, GA and
Athens, GA licenses to the Company. The Savannah and Athens Pops have not been
built, however, the Company expects that the Pops will be included in the
current build-out plan developed for the Company's existing footprint.

SERVICES AND FEATURES

  The Company intends to provide affordable, reliable, high-quality mobile
telecommunications service. Through its digital PCS network, the Company plans
to introduce a wide array of services and features that are designed to provide
customers with greater capabilities in call management and increase usage for
both outgoing and incoming calls.

  CONTIGUOUS FOOTPRINT.   The Company believes that its large contiguous
footprint, which is adjacent to AT&T's recently launched wireless network
markets of Washington, DC, Charlotte, NC and Atlanta, GA, will be a substantial
competitive advantage. The Company's affiliation with the "AT&T Wireless
Services Network" will provide the Company with access to nationwide coverage,
while its sizable home area, which will include adjacent AT&T wireless markets,
will allow the Company to offer cost-effective, competitive calling plans
stretching down much of the Mid-Atlantic and Southeastern coastal regions.

  IMPROVED QUALITY AND TECHNOLOGY.   As the quality of digital wireless
telephony networks continues to approach that of wireline systems, increased
customer usage is expected. The Company believes that PCS providers will in
general be the first to offer mass market all-digital mobile networks. In
addition, the Company believes PCS providers will be the first to be able to
offer mass market wireless applications in competition with switched and direct
access local telecommunications services.

  SINGLE NUMBER SERVICE.   This service will transfer all incoming calls between
primary landline and wireless locations automatically. When a customer's handset
is activated, the Company's network will route all incoming calls to the
customer's wireless number. When the handset is deactivated, all calls will be
directed to the customer's primary landline location. This advanced intelligent
network service application makes it possible for the customer to receive all
his or her calls and text messages through a single telephone number, enhancing
the "anytime, anywhere" functionality of the Company's wireless
telecommunications. This increased reachability will be managed through a set of
advanced features such as selective call screening, rejection, routing and
forwarding screening, caller ID, message waiting and call hold.

  CALLER ID, VOICEMAIL, MESSAGE WAITING INDICATOR, SHORT MESSAGING.   Caller ID
enables users to choose which calls to accept and which to send to voicemail, a
feature that will boost customer willingness to leave the phone on for incoming
calls. Digital voicemail is available at a very cost effective rate and allows
for fewer missed calls. Digital handset displays with message waiting indicators
will eliminate the need to "dial-in" to check voicemail, and will permit the
delivery of short messages similar to E-mail or alpha-numeric paging.

  MULTIMODE HANDSETS. Through multimode PCS handsets, the Company will offer
customers the ability to make and receive calls on both PCS and cellular
frequency bands utilizing both digital and analog technology. These advanced
handsets allow seamless roaming on cellular networks where compatible PCS
service is not offered and can be equipped for a variety of enhanced features
and applications.

  EXTENDED BATTERY LIFE.   New digital handsets are capable of operating in
"sleep mode" while powered on but not in use, thus improving efficiency and
extending battery life. The estimated effect of this capability is to extend

                                       6
<PAGE>
 
battery life to five to six times that of analog handsets. The Company expects
that this feature will increase usage, especially for incoming calls, as the
phone can be left on for longer periods.

  AUTHENTICATION, VOICE PRIVACY.    Through the use of an authentication key,
the digital technology eliminates the need for "PINs or Personal Identification
Numbers." Digital technology also offers enhanced privacy of calls. Each voice
signal is converted into a stream of data bits, which is encoded and then
separated. Greater privacy results, as it is more difficult for a call to be
decoded.

  WIRELESS DATA EXCHANGE.    The Company believes that, as data transmission
technologies develop, a number of potential uses for such services will emerge,
including short message service, mobile office applications (e.g., facsimile,
electronic mail and connecting notebook computers with the Internet and other
computer/data networks), access to stock quote services, transmission of text
such as maps and manuals, transmission of photographs, connections of wireless
point-of-sale terminals to host computers, monitoring of alarm systems,
automation of meter reading and monitoring of status and inventory levels of
vending machines.


MARKETING STRATEGY

  The Company intends to adopt a marketing approach that leverages AT&T's
nationwide presence and brand name. The Company expects to capitalize on its
regional focus and its ability, as a small, entrepreneurial company, to respond
quickly and creatively to changing customer needs. In all of its marketing
efforts, the Company intends to emphasize the improved quality, enhanced
features and favorable pricing of its PCS system. Its marketing strategy has
been designed to increase overall wireless communications penetration with an
emphasis on mass marketing concepts designed to appeal to a broad demographic
base.

  AFFILIATION WITH AT&T.   The Company intends to capitalize on the marketing
opportunities derived from the AT&T relationship, including (i) co-branding with
the AT&T logo, (ii) nationwide coverage, (iii) an expansive home calling area
and (iv) bundling of AT&T telecommunications products and service offerings.
See "Certain Relationships and Related Transactions--The AT&T Agreements."

  LOCAL FOCUS/CUSTOMER SERVICE.   The Company expects to benefit from its
intense focus on the Virginia, South Carolina, North Carolina and Georgia
markets. Operational executives will be close to the customer and better able to
build ties with the local community by emphasizing its regional identification.
The Company will employ full-time customer service representatives that are
extensively trained and authorized to solve customer's concerns/questions about
PCS services, activation, changing personal options, and other service
information. Customer service representatives will be accessible from any of the
Company's handsets at no charge.

  PRICING.   The Company's pricing strategy will be based upon simplified,
customer-friendly service plans allowing for customer preferred options and
"usage friendly" features. "Usage friendly" features will include long distance
throughout the continental U.S., caller ID, free first incoming minute and
selective routing to voicemail. The Company's consumer pricing strategy is
expected to result in low monthly access charges, region wide calling, usage-
enhancing features and low per-minute rates. Lower per-minute rates relative to
analog cellular providers are possible because digital cell and switch sites
have greater capacity, thereby enabling the Company to market high use customer
plans at significantly lower prices. Simultaneously, the Company will be able to
offer the business user substantial economic savings on such features as: home
regional roaming rates; free long distance throughout the contiguous United
States; messaging; and reduced rates for incoming calls.

  ADVERTISING.   The ability to benefit from the AT&T name and reputation will
allow the Company to achieve customer growth more efficiently than competitors
with low brand awareness. AT&T has spent billions of dollars nationally in
advertising to build its brand name. In addition to participating in nationwide
advertising campaigns promoting the AT&T brand name, the Company intends,
subject to the terms of the License Agreement, to advertise its products and
services using television, radio, print advertisements, outdoor advertising and
promotional displays in retail stores. The Company will market its products and
services under a local company name as "Member, AT&T Wireless Network" with the
AT&T logo. The focus of its advertising campaign will be "local folks providing
national wireless services."

  BUNDLING OF SERVICES.   In addition to its basic and enhanced wireless service
packages, the Company may bundle its wireless services with other
telecommunications services, including long distance services, through strategic
alliances and resale agreements. The Company may also seek to provide bundled
service options in partnership with local businesses and affinity marketing
groups. Examples include bundling wireless service with 

                                       7
<PAGE>
 
local telephone or utility services, banking services, cable television,
Internet access or alarm monitoring services, or with local information services
(permitting the customer to access information such as account status, weather
and traffic reports, stock quotes and sports scores as text messages from any
location).

  WIRELESS OFFICE.   The Company expects that one of its future product
orientations will be the "wireless office" plan featuring (i) a wireless PBX
with one handset for both on-premises and mobile use and (ii) separate pricing
plans for calls within and outside such premises. The interconnection through
PBX equipment provides (i) security through voice privacy and authentication,
(ii) all connections through least-cost routing, (iii) private-four-digit
dialing that can reach regional or national end-users, (iv) concurrent ringing
of landline and mobile phone, and (v) caller control to select the routing if no
answer. The flexibility in available pricing plans offered by wireless office is
expected to give the Company the opportunity to attract high volume end users to
its services. See "--TDMA Digital Technology."


SALES AND DISTRIBUTION

  The Company plans to target a broad range of consumer and business markets
utilizing a multi-channel sales plan. While the Company plans to have access to
AT&T's national sales channels, the Company also plans to offer its services and
products through traditional cellular channels, such as company retail stores,
mass merchandisers and retail outlets, a direct sales force and a third party
independent agent program, as well as through new, lower-cost channels such as a
corporate website and telemarketing. The Company is planning 7 to 12 retail
points of presence per 100,000 Pops. In total, the Company estimates that
approximately 60% to 70% of its gross additions will be generated by retail
distribution.

  RETAIL STORES.   The Company plans to open between 90 and 110 retail stores.
These stores are expected to provide the Company with the strong local presence
required to achieve high penetration in suburban and rural areas. Sales
representatives in corporate stores will receive in-depth training which will
allow them to explain PCS service in an informed and persuasive manner. The
Company believes that these representatives will foster effective and enduring
customer relationships.

  MASS MERCHANDISERS AND OUTLETS.   The Company's retail store strategy will be
complemented with mass market retail outlets in specifically identified areas in
which the Company believes that established retailers offer the highest
likelihood for success in reaching target customers. The Company also plans on
utilizing small in-line stores and kiosks in smaller areas of 8,000 Pops or
more.

  THIRD PARTY INDEPENDENT AGENT PROGRAM.   The Company's independent agent
strategy will create opportunities for distribution in areas that may not be
served by retail stores and mass merchandisers.

  AT&T MAJOR ACCOUNT TEAMS.   The Company plans on utilizing AT&T's Business
Marketing Division as a primary source of generating customers. Through
developing and implementing a cross sell services strategy, and creating an
administrative tracking system for referrals, the Company plans on providing
compensatory incentives for the AT&T Major Account Teams to promote and sell the
Company's product.

  DIRECT SALES FORCE.   The Company plans on servicing major accounts through a
direct sales force. The focus will be on those business accounts not covered by
AT&T's Business Marketing Division.

  WEBSITE AND TELEMARKETING.   The Company plans on developing these less
expensive and more innovative sales channels to complement the retail presence
within the Licensed Area as the build-out of the Initial Configuration nears
completion. The primary concept of sales through the website is to communicate
with customers in the way most preferred by that category of customer.

  Distribution of the Company's product can be divided into a two step process-
sale and activation. The Company's management intends to take advantage of the
technological features intrinsic to TDMA/IS-136 technology to separate the
activation of the phone from the sale of the phone. This separation will provide
several advantages to the Company, including: (i) higher quality service
activation than is normally the case through mass merchandising retail channels;
(ii) the opportunity for the Company to sell additional features, products or
customized services at the time of activation; and (iii) reduced churn because
customer expectations are set appropriately as basic training can be provided at
the time of activation.

                                       8

TDMA DIGITAL TECHNOLOGY

  The Company has selected TDMA digital technology utilizing the state-of-the-
art IS-136 standard for its PCS network. The Company selected TDMA on the IS-136
standard because it (i) offers quality digital service with enhanced service
capability, (ii) is compatible with AT&T's wireless network and (iii), in
comparison to CDMA technology, allows the Company to take advantage of
hierarchical cell sites to enhance coverage and create customized billing plans.

  The Company believes that systems using TDMA digital technology on the IS-136
standard offer three times the capacity of analog cellular systems and offer
enhanced transmission and routing capabilities, thus providing significantly
improved sound clarity relative to analog systems. TDMA digital technology also
allows the Company to offer an enhanced package of services to its customers,
including message waiting indicator, caller ID, sleep mode, voice privacy, short
message services, data communications, authentication and others.

  Since the Company has chosen the TDMA/IS-136 standard, its network will be
compatible with AT&T's nationwide network immediately upon launch of operations.
AT&T's network, together with that of the Company and other affiliates of AT&T,
is expected to span more than 80% of the United States.

  Finally, the Company has also chosen TDMA/IS-136 because it is capable of
providing a hierarchical cell site structure which allows cost-effective
capacity enhancement and greater customization of calling plans. An area covered
by a macro-cell site can be overlapped with the addition of micro-cells and
pico-cells to provide enhanced coverage within the same area. In addition, the
technology allows for customized billing by cell site, if necessary. This is
especially important in offering wireless office services. A pico-cell will
provide coverage within an office building and can be billed on a specialized
rate plan. As a user leaves the building, a micro-cell will provide localized
coverage for a "campus-based" environment that will be billed accordingly. When
the user leaves the specialized coverage area and is picked up by a macro-cell
site, they will then be billed as a traditional mobile customer.


NETWORK BUILD-OUT

  The build-out of the Company's network involves systems design, acquisition of
cell sites, equipment procurement, relocation of existing microwave users,
interconnection with other communications providers, construction of cell sites,
installation of switches, and testing, optimization and implementation of
advanced management information and billing systems. A planning, acquisition and
engineering team, composed of approximately 200 engineering employees,
independent contractors and consultants, is designing and constructing the
Company's digital PCS network based on the regional marketing and product
requirements to meet the Company's targets for consistency, uniformity and
reliability.

  The Company's principal objective is to maximize population coverage levels
within targeted demographic segments and geographic areas, rather than building
out wide-area cellular-like networks. The Company has commenced commercial
operations in the Initial Configuration and expects to cover 60% of the Pops in
the Licensed Area by the end of 1999. The Company expects to extend its coverage
to approximately 80% of the Pops in the Licensed Area by the end of the fourth
quarter of 2002.

  RF DESIGN. The Company, along with Wireless Facilities Inc., a radio frequency
engineering firm, developed the RF design for the initial build-out of its
digital PCS network in the Initial Configuration and will continue this
development for the 1999 build out plan. This process includes cell site design,
frequency planning and network optimization for each such market. Radio
frequency engineering also allocates voice channels and assigns frequencies to
cell sites taking into consideration both PCS and microwave interference issues.

  PROPERTY ACQUISITION. Four experienced vendors, Entel, Whalen, Crown
Communications, Inc. and American Tower Corporation are responsible for
identifying and obtaining the required property for build-out of the PCS
network, including securing all zoning, permitting and surveying approvals and
licenses. The cell site selection process will require the lease or acquisition
of approximately 500 sites prior to commencement of commercial operations of the
Company's PCS network in the Initial Configuration, an additional 500 sites in
the Company's 1999 build out plan and approximately 1,600 sites prior to full
operation in the Licensed Area, many of which are likely to require the Company
to obtain zoning variances or other local governmental or third-party approvals
or permits. As of February 28, 1999, the Company had signed leases or options
for 431 sites, 19 of which were awaiting required zoning approvals.

                                       9
<PAGE>
 
  CONSTRUCTION AND INSTALLATION.   The Company, along with Pacific 17, Inc.,
American Tower and Midwest Wireless Inc, will oversee the deployment of its
digital PCS network. These companies will act as construction management
contractors and employ local construction firms to build the cell sites.

  BUILD-TO-SUIT AGREEMENTS. The Company has entered into agreements with Crown 
Communications, Inc. ("Crown") and American Tower Corporation ("American"), 
whereby the Company will lease from Crown and American a portion of property and
communications facilities specific to areas to be built-out in the Company's 
Licensed Area.

  MICROWAVE RELOCATION.   The Company must clear its spectrum by relocating
certain commercial microwave service users within the Licensed Areas to become
operational. The Company has contracted with Entel to assist in the microwave
relocation process. Recently, the FCC adopted a microwave relocation cost-
sharing plan that limits permissible relocation costs and outlines new
procedures for the sharing of relocation costs where the relocation of private
microwave facilities benefits multiple broadband PCS licensees. See "--
Regulation."

  Analysis of the markets included in the 1999 build out plan has been completed
for all but 5 markets with no relocation required. The remaining markets are 
currently being analyzed which is expected to be completed by 1999.

  INTERCONNECTION.   The Company's digital PCS network will connect to local
exchange carriers. The Company has negotiated or intends to negotiate,
interconnection agreements with telephone companies operating or providing
service in the areas where the Company is deploying its digital PCS network. The
Company intends to use AT&T as its interexchange (long-distance) carrier as
provided in our stockholders' agreement.

  ROAMING.   Wireless service providers are able to offer service to customers
from other systems who are traveling in or through their service area. Customers
typically pay higher rates while "roaming" outside of their home market. Roaming
is made possible in today's analog and digital cellular environment by virtue of
common frequency and signaling technology. PCS and analog cellular systems
operate on different frequencies and with different signaling technologies.

  In areas where TDMA-based PCS service is not available, the Company offers a
roaming option on the traditional analog cellular and digital cellular systems
via dual-band/multi-mode handsets capable of transmitting over either cellular
or PCS frequencies. Access to cellular coverage is provided through the use of
dual-band/multi-mode handsets which first became commercially available in June
of 1997. Pursuant to the AT&T agreements, the Company's customers who own dual-
band/multi-mode handsets roam on AT&T's wireless network. In addition, pursuant
to the stockholders' agreement, AT&T has used commercially reasonable efforts to
enable the Company to become a party to the roaming agreements between AT&T and
other operators of cellular or PCS systems.

  INFORMATION TECHNOLOGY.   The Company has developed advanced and sophisticated
management information systems to handle customer care, billing, network
management and financial and administrative services. The systems are focused on
three primary areas: (i) customer care, including billing systems and customer
service and support systems, (ii) network management, including service
activation, traffic and usage monitoring, trouble management and operational
support systems and (iii) business systems, including financial, purchasing,
human resources and other administrative systems.

  The Company, together with its equipment vendors, has also introduced
sophisticated network management and operations support systems which facilitate
network fault detection, correction and management, performance and usage
monitoring and security. System capabilities are being developed which will
allow over-the-air activation of the handset and provision of services.

COMPETITION

   Competition for subscribers among wireless licensees is based principally
upon the services and features offered, the technical quality of the wireless
system, customer service, system coverage, capacity and price. Such competition
may increase to the extent that licenses are transferred from smaller, stand-
alone operators to larger, better capitalized and more experienced wireless
communications operators who may be able to offer subscribers certain network
advantages similar to those to be offered by the Company.

   Except in Myrtle Beach, the Company will initially compete directly with two
cellular providers in each of its Licensed Areas. The existing cellular
providers in the Company's markets, most of which have an infrastructure in
place and have been operational for a number of years, and several of which have
significantly greater financial and technical resources than the Company, may
upgrade their networks to provide comparable services in competition with the
Company. The technologies employed by these competitors are CDMA, whose relative
strengths as compared to TDMA include good voice quality and longer battery
life, and GSM, whose relative strengths as compared to TDMA include larger
system capacity, a low cost infrastructure, and international roaming
capabilities due to worldwide deployment.

   The Company will also compete with PCS license holders in each of its
markets. The Company believes that the ownership structure of PCS licenses in
the Licensed Area is fragmented. However, Sprint Corporation and BellSouth
Corporation, among others, hold licenses that overlap large portions of the
Licensed Area. The Company believes that most PCS license holders have not
commenced the roll-out of their networks in the Licensed Area. However, the
Company does expect to compete directly with one or more PCS service providers
in each of its markets in the future. 

   The Company expects to also face competition from other existing
communications technologies such as SMR and ESMR, currently employed by Nextel
in the Company's Licensed Area. Although SMR was originally created by the FCC
as a non-interconnected service principally for fleet dispatch, in the last
decade it has liberalized the rules to permit ESMR to offer services that are
functionally equivalent to cellular and PCS, and may be less expensive to build
and operate than PCS systems.

   The FCC requires all cellular and PCS licensees to provide service to
"resellers." A reseller provides wireless service to customers but does not hold
an FCC license or own facilities. Instead, the reseller buys blocks of wireless
telephone numbers and capacity from a licensed carrier and resells service
through its own distribution network to the public. Thus, a reseller is both a
customer of a wireless licensee's services and also a competitor of that
licensee. Several small resellers currently operate in competition with the
Company. Several years ago the FCC initiated an administrative proceeding
seeking comment on whether resellers should be permitted to install separate
switching facilities in cellular systems, although it tentatively concluded not
to require such interconnections; this issue remains pending at the FCC.
Presently the FCC does not require CMRS providers to offer interconnection to
all other CMRS providers, but it has stated that it will consider
interconnection complaints on a case-by-case basis and that it may consider in
the future whether to impose more general interconnection obligations on CMRS
providers. The FCC is also considering whether resellers should receive direct
assignments of telephone numbers from the North American Numbering Plan
Administrator. With respect to PCS licensees, the resale obligations terminate
five years after the last group of initial licenses of currently allotted PCS
spectrum is awarded.

   It is likely that the FCC will offer additional spectrum for wireless mobile
licenses in the future. Applicants also have received and others are seeking FCC
authorization to construct and operate global satellite networks to provide
domestic and international mobile communications services from geostationary and
low earth orbit satellites. One such system, the Iridium system, began
commercial operations in 1998.The Company anticipates that market prices for 
two-way wireless services generally will decline in the future based upon 
increased competition. The Company's ability to compete successfully will 
depend, in part, on its ability to anticipate and respond to various competitive
factors affecting the industry, including new services that may be introduced,
changes in consumer preferences, demographic trends, economic conditions and
competitors' discount pricing strategies, all of which could adversely affect
the Company's operating margins. The Company plans to use its digital feature
offerings, national network through its AT&T affiliations, contiguous footprint
providing an expanded home rate billing area, and local presence in secondary
markets, to combat potential competition. The Company expects that its extensive
digital network, once deployed, will provide the cost effective means to react
effectively to any price competition.


REGULATION

   The FCC regulates the licensing, construction, operation, acquisition and
sale of PCS systems in the United States pursuant to the Communications Act, as
amended from time to time, and the rules, regulations and policies promulgated
by the FCC thereunder.

 Licensing of PCS Systems

   A broadband PCS system operates under a protected geographic service area
license granted by the FCC for a particular market on one of six frequency
blocks allocated for broadband PCS service. Narrowband PCS is for non-voice
applications such as paging and data service and is separately licensed. The FCC
has segmented the United States into PCS markets as follows: 51 large regions
called MTAs, which in turn are comprised of 493 smaller regions called BTAs. Two
licenses are awarded for each MTA and four for each BTA, so that generally six
licensees will be authorized to compete in each area. The two MTA licenses
authorize the use of 30 MHz of spectrum. One of the BTA licenses is for 30 MHz
of spectrum, and the other three are for 10 MHz each. The FCC permits licensees
to split their licenses and assign a portion, on either a geographic or
frequency basis or both, to a third party. It was in this fashion that AT&T
assigned to the Company 20 MHz of its 30 MHz licenses covering the Licensed
Area.

   The FCC awards initial PCS licenses by auction. Auctions began with the 30
MHz, MTA-wide licenses, and concluded last year with the last of the BTA
licenses. In March, 1998, the FCC adopted an order that allows financially
troubled entities that won C-Block licenses at auction to obtain financial
relief from their payment obligations and to return some or all of their C-Block
licenses to the FCC for reauctioning. The FCC began the reauction of the
returned licenses in March, 1999. This action will place additional spectrum in
the hands of potential competitors of the Company. The FCC may reauction other
licenses that are returned by bidders or that are subject to default.

   Under the FCC's current rules specifying spectrum aggregation limits
affecting broadband PCS licensees, no entity may hold "attributable" interests
(generally 20% or more of the equity, or an officer or director position) in
licenses for more than 45 MHz of PCS, cellular and certain SMR services where
there is significant overlap in any geographic area. Significant overlap will
occur when at least ten percent of the population of the PCS licensed service
area is within the cellular and/or SMR service area(s).

   All PCS licenses have a 10-year term, at the end of which they must be
renewed. The FCC will award a "renewal expectancy" to a PCS licensee that (i)
has provided substantial service during its past license term and (ii) has
substantially complied with applicable FCC rules and policies and the
Communications Act. All PCS licensees must satisfy certain coverage
requirements. In the Company's case, it must construct facilities that offer
coverage to one-third of the population of its service area within five years of
the original license grants to AT&T and to two-thirds of the population within
ten years. Licensees that fail to meet the coverage requirements may be subject
to forfeiture of the license.

   For a period of up to five years after the grant of a PCS license (subject to
extension), a PCS licensee will be required to share spectrum with existing
licensees that operate certain fixed microwave systems within its Licensed Area.
To secure a sufficient amount of unencumbered spectrum to operate its PCS
systems efficiently and with adequate population coverage, the Company will need
to relocate many of these incumbent licensees. In an effort to balance the
competing interests of existing microwave users and newly authorized PCS
licensees, the FCC has adopted (i) a transition plan to relocate such microwave
operators to other spectrum blocks and (ii) a cost sharing plan so that if the
relocation of an incumbent benefits more than one PCS licensee, the benefiting
PCS licensees will share the cost of the relocation. Initially, this transition
plan allowed most microwave users to operate in the PCS spectrum for a two-year
voluntary negotiation period and an additional one-year mandatory negotiation
period. For public safety entities dedicating a majority of their system
communications for police, fire or emergency medical services operations, the
voluntary negotiation period is three years, with an additional two-year
mandatory negotiation period. The FCC has recently shortened the voluntary
negotiation period by one year (without lengthening the mandatory negotiation
period) for non-public safety PCS licensees in the C, D, E and F Blocks. Parties
unable to reach agreement within these time periods may refer the matter to the
FCC for resolution, but the incumbent microwave user is permitted to continue
its operations until final FCC resolution of the matter. The transition and cost
sharing plans expire on April 4, 2005, at which time remaining incumbents in the
PCS spectrum will be responsible for their costs to relocate to alternate
spectrum locations.

   PCS systems are subject to certain FAA regulations governing the location,
lighting and construction of transmitter towers and antennas and may be subject
to regulation under the National Environmental Policy Act and the environmental
regulations of the FCC. State or local zoning and land use regulations also
apply to the Company's activities. The Company expects to use common carrier
point to point microwave facilities to connect Cell Sites and to link them to
the main switching office. These facilities are separately licensed by the FCC
and are subject to regulation as to technical parameters and service.

   The Communications Act preempts state and local regulation of the entry of,
or the rates charged by, any provider of CMRS, which includes PCS and cellular
service, or any private mobile radio service ("PMRS"), and the FCC does not
regulate such rates.


 Transfers and Assignments of PCS Licenses

   The Communications Act and FCC rules require the FCC's prior approval of the
assignment or transfer of control of a license for a PCS or cellular system. In
addition, the FCC has established transfer disclosure requirements that require
licensees who transfer control of or assign a PCS license within the first three
years of their license term to file associated contracts for sale, option
agreements, management agreements or other documents disclosing the total
consideration that the licensee would receive in return for the transfer or
assignment of its license. Non-controlling interests in an entity that holds a
FCC license generally may be bought or sold without FCC approval. Any
acquisition or sale by the Company of PCS or cellular interests may also require
the prior approval of the Federal Trade Commission and the Department of
Justice, if over a certain size, as well as state or local regulatory
authorities having competent jurisdiction.


 Foreign Ownership

   Under existing law, no more than 20% of an FCC licensee's capital stock may
be owned, directly or indirectly, or voted by non-US citizens or their
representatives, by a foreign government or its representatives or by a foreign
corporation. If an FCC licensee is controlled by another entity, as is the case
with the Company's ownership structure, up to 25% of that entity's capital stock
may be owned or voted by non-US. citizens or their representatives, by a foreign
government or its representatives or by a foreign corporation. Foreign ownership
above the 25% level may be allowed should the FCC find such higher levels not
inconsistent with the public interest. The FCC has recently issued an order in
which it ruled that higher levels of foreign ownership (even up to 100%) are
presumptively consistent with the public interest with respect to investors from
most nations. If foreign ownership of the Company were to exceed the permitted
level, the FCC could revoke the Company's FCC licenses, although the Company
could seek a declaratory ruling from the FCC allowing the foreign ownership or
take other actions to reduce the Company's foreign ownership percentage in order
to avoid the loss of its licenses. The Company has no knowledge of any present
foreign ownership in violation of these restrictions.


 Recent Industry Developments

   The FCC has announced rules for making emergency 911 services available by
cellular, PCS and other mobile service providers, including "enhanced 911"
services that provide the caller's telephone number, location and other useful
information. The original timetable required PCS providers to be able to process
and transmit 911 calls (without call validation), including those from callers
with speech or hearing disabilities, by late 1997, to take actions enabling them
to relay a caller's automatic number identification and cell site by mid-1998,
and by 2001 to be able to identify the location of a 911 caller within 125
meters in 67% of all cases. The FCC is currently considering a revised
implementation schedule for these requirements State actions incompatible with
the FCC rules are subject to preemption.

   On August 1, 1996, the FCC released a Report and Order expanding the
flexibility of cellular, PCS and other CMRS providers to provide fixed as well
as mobile services. Such fixed services include, but need not be limited to,
"wireless local loop" services, e.g., to apartment and office buildings, and
wireless backup to PBXs and local area networks, to be used in the event of
interruptions due to weather or other emergencies. The FCC has not yet decided
whether such fixed services should be subjected to universal service
obligations, or how they should be regulated, but it has proposed a presumption
that they be regulated as CMRS services.

   On August 8, 1996, the FCC released its order implementing the
interconnection provisions of the Telecommunications Act. The FCC's decision is
lengthy and complex and is still subject to further review, and its precise
impact is difficult to predict with certainty. Although many of the provisions
of this order were struck down by the United States Court of Appeals for the
Eighth Circuit, the rationale of the order has been adopted by many states'
public utility commissions, with the result that the charges that cellular and
PCS operators pay to interconnect their traffic to the public switched telephone
network are expected to decline significantly from pre-1996 levels.

     In its implementation of 1996 Act, the FCC established federal universal
service requirements that affect CMRS operators.  Under the FCC's rules,
wireless service providers potentially are eligible to receive universal service
subsidies for the first time; however, they also are required to contribute to
both federal and state universal service funds.  Many states are also moving
forward to develop state universal service fund programs.  A number of these
state funds require contributions, varying greatly from state to state, from
CMRS carriers.  Multiple parties have challenged various aspects the FCC's
universal service order and the cases have been consolidated in the United
States Court of Appeals for the Fifth Circuit in New Orleans.  A judicial
determination adverse to the FCC, as well as any further modification to the
FCC's universal service rules, could affect the CMRS carrier support payments
required for federal and state universal service programs.

   The FCC recently adopted rules on telephone number portability which will
enable customers to migrate their landline and cellular telephone numbers to a
PCS or cellular carrier and from a PCS or cellular carrier to another service
provider. The FCC has also adopted rules requiring PCS and cellular operators to
provide functions to facilitate electronic surveillance by law enforcement
officials. Representatives of the cellular and PCS industry are challenging both
sets of rules.

     The FCC has determined that the interstate, interexchange (commonly
referred to as long distance) offerings of CMRS providers are subject to the
interstate, interexchange rate averaging and integration provisions of the
Communications Act.  Rate averaging requires the Company to average its
interstate long distance CMRS rates between high cost and urban areas.  The FCC
has delayed implementation of the rate integration requirements with respect to
"wide area" rate plans offered by the Company pending further reconsideration of
its rules.  The FCC also delayed the requirement that there be CMRS long
distance rate integration among the Company's CMRS affiliates.  On December 31,
1998, the FCC reaffirmed on reconsideration that its interexchange rate
integration rules apply to interexchange CMRS services.  The FCC announced it
would initiate a further proceeding to determine how integration requirements
apply to typical CMRS offerings, including "One-Rate" plans.  Until this further
proceeding is concluded, the FCC will enforce only CMRS long distance rate
integration on the Company's services where an interstate toll charge is
separately stated and billed to CMRS customers.  To the extent that the Company
offers services subject to the FCC's rate integration and averaging
requirements, these requirements generally reduce the Company's pricing
flexibility for its services. There can be no assurance that the FCC will
decline to impose rate integration or averaging requirements on the Company or
decline to require the Company to integrate its CMRS long distance rates across
its CMRS affiliates.

     The FCC recently adopted new rules limiting the use of customer proprietary
network information ("CPNI") by telecommunications carriers, including the
Company, in marketing a broad range of telecommunications and other services to
their customers, and the customers of affiliated companies.  The FCC has
received numerous petitions for reconsideration of its CPNI rules, the majority
of them from CMRS carriers.  The FCC has stayed portions of its rules that
relate to how carriers identify CPNI that a customer has restricted,
particularly the portion of the rules that requires all carriers to develop an
electronic auditing and compliance system.  This stay will extend for six months
after the date that the CPNI rules are reconsidered.  The Company does not
anticipate that the rules will result in a significant adverse impact on its
financial position, results of operation or liquidity.

     In addition, state commissions have become increasingly aggressive in their
efforts to conserve numbering resources.  These efforts may disproportionately
impact wireless service providers by imposing additional costs or limiting
access to numbering resources.  Examples of state conservation methods include
number pooling, number rationing and transparent overlays. Number pooling is
especially problematic for wireless providers because it is dependent on number
portability technology.  In addition, transparent overlays have been rejected by
the FCC, although that decision is currently being reconsidered by the FCC.
Recently, the FCC released a public notice soliciting comment on proposed number
optimization methods discussed in a report prepared by the Resource Optimization
Working Group of the North American North American Numbering Council.  Adoption
of some of the methods discussed in the report could have a disproportionate
impact on CMRS operators.

     The FCC is also considering adopting rules to govern customer billing by
telecommunications services providers such as the Company.  The FCC proposed
that more billing detail be provided to consumers, which could add to the
expense of the billing process as systems are modified to conform to any new
requirements.  Additionally, the FCC is also considering whether carriers, such
as the Company, that decide to pass through their mandatory universal service
contributions to their customers, should be required to provide a full
explanation of the program and ensure that the carriers that pass through their
contribution do not over recover their mandatory contributions from their
customers.  Adoption of some of the FCC's proposals could increase the
complexity of the Company's billing processes and restrict the Company's ability
to bill customers for services in the most commercially advantageous way.

     In April, 1998, the FCC initiated an administrative rulemaking proceeding
to determine the obligations of  telecommunications carriers to make their
services accessible to individuals with disabilities.  The FCC has proposed
regulations implementing statutory requirements governing accessibility of
telecommunications services like those offered by the Company to persons with
disabilities, and could adopt proposals requiring modifications to existing
customer equipment as well as requirements governing new equipment and carrier
networks.


STATE REGULATION AND LOCAL APPROVALS

     The states in which the Company presently operates currently do not
regulate wireless service.  In the 1993 Budget Act, Congress gave the FCC the
authority to preempt states from regulating rates or entry into CMRS, including
PCS and cellular.  The FCC, to date, has denied all state petitions to regulate
the rates charged by CMRS providers.  States may, however, regulate the "other
terms and conditions" of CMRS service.  The siting of cells also remains subject
to state and local jurisdiction, although petitions seeking clarification of
states' siting authority are currently pending at the FCC.

INTELLECTUAL PROPERTY

   The AT&T globe design logo is a service mark registered with the United
States Patent and Trademark Office. The service mark is owned by AT&T. The
Company expects, pursuant to the License Agreement, to use, royalty-free, the
AT&T and globe design logo and certain other service marks of AT&T in connection
with marketing, offering and providing Licensed Services (as defined herein) to
end-users and resellers, solely within the Licensed Area. The License Agreement
also grants to the Company the right and license to use the Licensed Marks on
certain permitted mobile phones.

   Except in certain instances, AT&T has agreed not to grant to any other person
a right or license to provide or resell, or act as agent for any person
offering, Licensed Services under the Licensed Marks. In all other instances,
AT&T reserves for itself and its affiliates the right to use the Licensed Marks
in providing its services (subject to its exclusivity obligations described
above), whether within or without the Licensed Area.

   The License Agreement contains numerous restrictions with respect to the use
and modification of any of the Licensed Marks. 

EMPLOYEES

   As of February 28, 1998, the Company had approximately 493 employees.  The
Company anticipates that the continued development of its Licensed Area will
require the hiring of a substantial number of new employees.  The Company's
management considers its employee relations to be good.

ITEM 2.  PROPERTIES

  The Company maintains its corporate headquarters in Malvern, PA.  The Company
leases this space. The Company maintains two regional headquarters, in Richmond,
VA and Charleston, SC, also leasing theses spaces. In addition to its corporate
and regional headquarters, the Company leases sales and administrative offices,
and leases and owns locations for cell sites and switching equipment. The
Company reviews these leases from time to time and may, in the future, lease or
acquire new facilities as needed. The Company does not anticipate that it will
encounter any material difficulties in meeting needs for any leased space.

FORWARD-LOOKING STATEMENTS

   When used in this Form 10-K and in future filings by the Company with the
SEC, in the Company's press releases and in oral statements made with the
approval of an authorized executive officer of the Company, the words or phrases
"will likely result," "management expects" or "the Company expects," "will
continue," "is anticipated," "estimated" or similar expressions (including
confirmations by an authorized executive officer of the Company or any such
expressions made by a third party with respect to the Company) are intended to
identify "forward-looking statements" within the meaning of the Private
Securities Litigation Reform Act of 1995. Readers are cautioned not to place
undue reliance on any such forward-looking statements, each of which speaks only
as of the date made. Such statements are subject to certain risks and
uncertainties that could cause actual results to differ materially from
historical earnings and those presently anticipated or projected. The Company
has no obligation to release publicly the result of any revisions, which may be
made to any forward-looking statements to reflect anticipated or unanticipated
events or circumstances occurring after the date of such statements.

GENERAL

   The following discussion and analysis is based upon the combined financial
statements of the Company and its predecessor, Triton L.L.C. for the periods
presented herein, and should be read in conjunction with the combined financial
statements.

   On March 6, 1997, Triton L.L.C. was formed to explore various business
opportunities in the wireless telecommunications industry, principally related
to PCS and cellular activities.  During the period March 6, 1997 through October
1, 1997, Triton L.L.C.'s activities consisted principally of hiring a management
team, raising capital, and negotiating strategic business relationships,
primarily related to PCS business opportunities.  Subsequent to October 2, 1997,
these activities continued but were conducted primarily through the Company.
Consequently, for purposes of the accompanying financial statements, L.L.C. has
been treated as a "predecessor" entity. As a result of certain financing
relationships and the similar nature of the business activities conducted by
each respective legal entity, Triton L.L.C. and the Company are considered
companies under common control.

OVERVIEW

   The Company intends to become a leading provider of wireless broadband PCS in
the southeastern United States. The Company was established by Michael Kalogris,
Steven Skinner and other former executives of Horizon, along with various equity
investors, with the intent to develop and operate a leading PCS network in the
Southeast. In October 1997, the Company entered into a joint venture agreement
with AT&T, whereby the Company will be the exclusive provider of wireless
mobility services under the AT&T consumer brand name in a contiguous area
covering approximately 11 million Pops in the southeastern United States. AT&T
contributed the PCS Licenses to Triton covering the Licensed Area in exchange
for an equity interest in Holdings. Additionally, the Company is a party to
agreements with AT&T that, among other things, allow the Company to benefit from
AT&T's nationwide wireless footprint and promotional and marketing efforts and
provide the Company with favorable roaming and long distance rates for services
on AT&T's wireless and long distance networks. See "Certain Relationships and
Related Transactions--The AT&T Agreements." The PCS Licenses authorize the
Company to provide PCS services to such major population and business centers as
Charleston, SC, Columbia, SC, Greenville/Spartanburg, SC, Richmond, VA and
Augusta, GA, as well as major resort destinations such as Myrtle Beach, SC,
Hilton Head, SC and Kiawah Island, SC. The Company commenced commercial
operations in the first quarter of 1999.

     On June 30, 1998, the Company acquired an existing cellular system which
serves Myrtle Beach, SC and the surrounding area, from Vanguard Cellular System
of South Carolina, Inc. for a purchase price of approximately $164.5 million.
The Company believes it will seamlessly integrate the Myrtle Beach system, which
uses digital TDMA/IS-136 cellular technology, into its planned PCS network as
part of the Initial Configuration. Since the Myrtle Beach system is within the
Licensed Area, it operates under the AT&T agreements. The Company believes that
the Myrtle Beach acquisition has (i) provided the Company with a system that
currently generates positive cash flow, (ii) accelerated the ability of the
Company to capture roaming traffic generated by Myrtle Beach's highly transitory
population, (iii) accelerated the Company's time-to-market in South Carolina and
(iv) rendered a PCS build-out in the Myrtle Beach region unnecessary.

   On December 31, 1998, the Company acquired from AT&T (i) an FCC license to
use 20 MHz of authorized frequencies to provide broadband PCS services
throughout the entirety of the Norfolk, Virginia BTA and (ii) certain assets of
AT&T used in the operation of the PCS system in such BTA for an aggregate
purchase price of approximately $111 million. The build-out of the network
relating to the Norfolk Acquisition, including the installation of a switch, has
been substantially completed and the Norfolk BTA commenced commercial operations
in the first quarter of 1999. With the Norfolk Acquisition, the Company's
contiguous footprint totals approximately 13 million Pops.

POTENTIAL EXCHANGE

   On March 24, 1998, the Company entered in a non-binding letter of intent
related to certain transactions, including the potential acquisition of 1.9
million additional net incremental Pops, and the exchange of the Hagarstown, MD
and Cumberland, MD BTAs. The agreement has been modified to only include the
exchange of 512,000 Pops located in the hagerstown, MD and Cumberland, MD BTAs
for 517,000 Pops located in certain countries in Savannah, GA and Athens, GA
BTAs, all of which are contiguous to the Company's existing service area. Due to
the difference in value per Pop of the BTAs exchanged, consideration of
approximately $9.7 million, all of which is expected to be represented by non-
cash equity interests in Triton PCS Holdings Company, Inc. (Holdings) will be
issued to AT&T. The transaction is subject to execution of a definitive exchange
agreement and closing conditions typical in transactions of the nature. If the
agreement and closing condition typical in transactions of this nature. If the
transaction is consummated, Holdings intends to contribute to the Savannah, GA
and Athens, GA licenses to the Company. The Savannah and Athens Pops have not
been built, however, the Company expects that the Pops will be included in the
current build-out plan developed for the Company's existing footprint.

   To date, the Company has incurred expenditures in connection with the
establishment of its business, raising capital, the initial design and
construction of its PCS network, and engineering, marketing, administrative and
other start-up related expenses. The Company has commenced commercial operations
in the Initial Configuration during the first quarter of 1999. Upon completion
of the Initial Configuration, the Company intends to target the remaining
cities, connecting highway corridors and counties along the interstates with
population densities of 50 or more per square mile. The Company expects to
extend its coverage to approximately 80% of the Pops in the Licensed Area by the
end of the fourth quarter of 2002, which the Company believes will generally
provide greater coverage than current cellular operators in such markets. The
extent to which the Company is able to generate operating revenues and earnings
is dependent on a number of business factors, including construction of the
network at or below its estimated costs, successfully deploying the PCS network
and attaining profitable levels of market demand for the Company's products and
services.

RESULTS OF OPERATIONS

YEAR ENDED DECEMBER 31, 1998 COMPARED TO THE PERIOD FROM MARCH 6, 1997 TO
DECEMBER 31, 1997

     Revenues for year ended December 31, 1998 were $16.6 million related
primarily to services provided in the Myrtle Beach area.  Service revenues were
$15.8 million for the year and equipment revenues were $0.8 million.

     Total operating expenses were $36.0 million for the year ended December 31,
1998 as compared to $2.7  million for the period from March 6, 1997 to December
31, 1997.  Cost of service revenues and equipment revenues were $4.3 million and
$1.7 million, respectively, and relate primarily to services provided in the
Myrtle Beach area.  Cost of operations were $13.0 million and relate primarily
to the operation and maintenance of the Myrtle Beach network as well as the
initial operating costs in the Company's remaining Licensed Area.

     Sales and marketing expenses were $1.7 million for the year ended December
31, 1998, and relate primarily to advertising, marketing and promotional
activities associated with the Myrtle Beach area.

     General and administrative expenses increased $5.9 million to $8.6 million
for the year ended December 31, 1998 as compared to the period from March 6,
1997 to December 31, 1997.  The increase was due primarily to administrative
costs associated with Myrtle Beach and the establishment of the Company's
corporate and regional operational infrastructure.

     For the year ended December 31, 1998, depreciation and amortization expense
was $6.7 million. This amount relates primarily to the depreciation of the
tangible and intangible assets acquired in the Myrtle Beach transaction and
amortization attributable to certain agreements acquired in the AT&T
transaction.

     For the year ended December 31, 1998, interest expense was $30.4 million,
net of capitalized interest of $3.5 million as compared to $1.2 million during
the period from March 6, 1997 to December 31, 1997. The Company had borrowings
of $463.6 million as of December 31, 1998, with a weighted average interest rate
of 10.33%.

                                       13
<PAGE>
 
     For the year ended December 31, 1998, interest and other income was $10.6
million.  This amount relates primarily to interest income on the Company's cash
and cash equivalents.  Available cash increased significantly during 1998 due
primarily to net proceeds of $291 million from the issuance of subordinated
debt, borrowings of $150 million under the Company's bank credit facility, and
$82.7 million of capital contributions.

     For the year ended December 31, 1998, the Company recorded a tax benefit of
$ 7.5 million related to temporary deductible differences, primarily net
operating losses, arising during the current and prior year.

     For the year ended December 31, 1998, the net loss was $31.6 million as
compared to $4.0 million during the period from March 6, 1997 to December 31,
1997. The net loss increased $27.6 million, resulting primarily from the items
discussed above.

LIQUIDITY AND CAPITAL RESOURCES

Net Cash Used In Operating Activities

   For the year ended December 31, 1998, net cash used in operating activities
increased $3.0 million to $4.1 million as compared to the period from March 6,
1997 to December 31, 1997. The increase is due primarily to an increase in the
Company's net loss, as adjusted to cash used in operating activities before
changes in working capital, of $9.8 million, offset by a positive change in
working capital of $5.7 million due to increases in accounts payable and accrued
expenses related to the operations in the Myrtle Beach area and the ongoing
establishment of the Company's corporate and regional operational
infrastructures.

Net Cash Used in Investing Activities

   For the year ended December 31, 1998, net cash used in investing activities
increased $371.9 million to $372.3 million as compared to the period from March
6, 1997 to December 31, 1997.  The increase is due primarily to capital
expenditures related to the initial network build-out and establishment of
administrative operations, payments of $164.5 million attributable to the Myrtle
Beach Acquisition completed on June 30, 1998, and payments of $96.6 million
related to the Norfolk Acquisition completed on December 31, 1998.  The Company
also made investments in marketable securities of $23.6 million during the year.

Net Cash Provided By Financing Activities

   For the year ended December 31, 1998, net cash provided by financing
activities increased $498.4 million to $511.3 million as compared to the period
from March 6, 1997 to December 31, 1997. The increase was due primarily to
proceeds from borrowings under our bank credit facility of $150 million;
proceeds from the issuance of subordinated debt of $291 million, net of an
initial purchasers discount of $9.0 million; and capital contributions of $82.7
million from Holdings related to funding of capital commitments by the initial
cash equity investors and receipt of additional capital commitments related to
the Myrtle Beach and Norfolk acquisitions.

Liquidity

   The build-out of the Company's PCS network and the marketing of the Company's
PCS services will require substantial capital. As it completes its build-out,
the Company will be highly leveraged. The Company currently estimates that its
capital requirements (including capital expenditures, working capital, debt
service requirements and anticipated operating losses) for the period from
inception through year-end 2002 (assuming substantial completion of the
Company's network build-out to cover 80% of the Pops in the Licensed Area by
such time) will total approximately $715.1 million. Actual amounts of the funds
required may vary materially from these estimates.

   As part of the Company's network build-out, the Company expects to spend
$272.0 million in 1999 related to the completion of the build-out of its initial
coverage area and its continued build out of the Company's Licensed Area toward
coverage of 80% which is expected in 2002. The build-out of the initial coverage
area included the installation of two switches and the lease or acquisition of
approximately 500 cell sites, as well as spectrum clearing costs, retail store
fitout, and administrative systems. The continuation of the build out of the
Company Licensed Area in 1999 includes completion of an additional 513 cell
sites. Other capital expenditures budgeted for 1999 include an aggregate of $19
million to be spent on administrative systems, spectrum clearing and switch
software. The preceding capital forecasts exclude internal engineering and
capitalized interest costs.

   The Cash Equity Investors have severally made irrevocable commitments to
contribute $140 million in cash to the Company through January 2001 in exchange
for 1.4 million shares of Series C preferred stock. The Cash Equity Investors,
have contributed $80 million of these commitments and are obligated to
contribute the balance as follows: $35 million on February 4, 2000 and $25
million on February 4, 2001. In addition, the Company has received additional
equity contributions of $35.0 million and $16.5 million from Holdings related to
the Myrtle Beach and Norfolk acquisitions, respectively.

   On February 3, 1998, the Company entered into a bank credit facility. This
credit facility provides for (i) a $175 million, eight and one-half year Tranche
A term loan, (ii) a $150 million, nine and one-quarter year Tranche B term loan
and (iii) a $100 million, eight and one-half year revolving credit facility. The
commitment to make revolving credit loans is reduced automatically beginning on
August 3, 2004 and the term loans must be repaid beginning on February 3, 2002.
In addition, the credit facility requires the Company to make mandatory
prepayments of outstanding borrowings under the credit facility commencing with
the fiscal year ending December 31, 2001 based on a percentage of excess cash
flow, and contains customary financial and other covenants. To date, $150
million of the Tranche B term loans have been drawn by the Company, which are
expected to fund the Company's future operations. Borrowings under the
facilities are secured by a first priority pledge of all assets of the Company,
including the capital stock of the Company and its subsidiaries that hold the
PCS licenses.

   On May 7, 1998, the Company completed an offering of $512 million aggregate
principal amount at maturity of 11% senior subordinated discount notes due 2008,
pursuant to Rule 144A of the Securities Act of 1933, as amended. The proceeds of
the offering (after deducting an initial purchaser's discount of $9 million) was
$291 million. The Company has used or intends to use the net proceeds from the
offering, together with the capital contributions and borrowings under the
credit facility, to fund: (i) capital expenditures, including the build-out of
its PCS network; (ii) the acquisition of the Myrtle Beach system; (iii) the
Norfolk acquisition; (iv) working capital as required; (v) operating losses;
(vi) general corporate purposes; and (vii) potential acquisitions.

   The Company believes that the proceeds from the notes, together with the
availability under the credit facility and the Equity Investments, provide
the Company with funds sufficient to complete the build-out of the Company's
planned network within the Licensed Area.

NEW ACCOUNTING PRONOUNCEMENTS

   In April 1998, the Accounting Standards Executive Committee of the AICPA
issued Statement of Position  98-5, Reporting on the Costs of Start-up
Activities ("SOP 98-5").  This statement requires that the costs of start-up
activities, including organization costs, be expensed as incurred and is
effective for fiscal years beginning after December 31, 1998.  The Company has
elected early adoption of this statement as of January 1, 1998.  The initial
application of the statement did not have a material effect on the Company's
financial statements.

   In June 1997, the FASB issued Statement No. 131, "Disclosure About Segments
of an Enterprise and Related Information" ("SFAS 131"). This statement
establishes additional standards for segment reporting in the financial
statements and is effective for fiscal years beginning after December 15, 1997.
The Company adopted SFAS 131 and determined that there are no separate segments,
as defined by the standards.

   In June 1998, the FASB issued Statement No. 133, "Accounting for Derivative
Instruments and Hedging Activities" ("SFAS 133") which establishes accounting
and reporting standards for derivative instruments, including certain derivative
instruments imbedded in other contracts and for hedging activities. SFAS 133 is
effective for fiscal years beginning after June 15, 1999. The application of
this statement is not expected to have a material effect on the Company's
financial statements.

INTEREST RATE RISK MANAGEMENT POLICIES

The Company's interest rate risk management program focuses on minimizing 
exposure to interest rate movements, setting an optimal mixture of floating and 
fixed rate debt, and minimizing liquidity risk. To the extent possible, the 
Company manages interest rate exposure and the floating and fixed ratio through 
its borrowings, but sometimes uses interest rate swaps to adjust its risk 
profile. The Company selectively enters into interest rate swaps to manage 
interest rate exposure only.

YEAR 2000 DISCLOSURE

   The Year 2000 issue is the result of computer programs being written using
two digits rather than four digits to define the applicable year. Computer
programs that have time-sensitive software may recognize a date using "00" as
the year 1900 rather than the year 2000. This could result in a system failure
or miscalculations causing disruptions of operations, a temporary inability to
process transactions, send invoices, or engage in normal business activities.

                                       15
<PAGE>
 
   Currently, the Company is actively taking measures to eliminate or mitigate
the impact of any issues associated with the Year 2000.  To that end, a project
team with senior management sponsorship has been established to provide
centralized coordination for the Company's Year 2000 related activities.

   This team is currently conducting the inventory and assessment phase of the
program. Although the majority of the software, hardware and firmware deployed
as part of our start-up operation was procured to the latest revision levels and
believed to be year 2000 capable, our process requires a re-verification of the
Year 2000 readiness capabilities with the vendors, suppliers and third party
providers.  All suppliers and third-party vendors deemed critical to the
function of the Company are being surveyed to ensure readiness and non-
disruption to the Company's operations.  Through this assessment and surveying
process, we are identifying those remediation efforts necessary to ensure our
systems and applications will continue to operate without interruption prior to,
during and after the Year 2000.  However, we can provide no assurance that the
information provided by the vendors, suppliers and third party providers, upon
whom we rely for our services, is accurate. As such, we can make no guarantee
that inaccurate information provided to us could not have a material effect upon
our Company.

   To date, our assessments have shown that the Company's main switching and
transmission equipment, with the exception of the Myrtle Beach operational
systems, is capable of correctly recognizing and processing date sensitive
information. This capability was further demonstrated through inter-operability
testing conducted by the Cellular Telecommunications Industry Association. In
addition to the wireless operational infrastructure, initial assessments of
support system providers have revealed some products and applications that are
not currently in a conforming status. In all identified instances to date, the
supplier(s) of those products or applications have identified that their
product(s) will be compliant by the end of the second quarter of 1999. However,
there can be no guarantee that the systems of other companies which the Company
relies on will be converted on a timely basis, or that a failure to convert by
another company would not have a material adverse effect on the Company.

   As part of the Myrtle Beach acquisition, the operational and financial
systems were to be migrated to the systems being deployed as part of the
Company's PCS start-up plan. The Myrtle Beach financial systems were
successfully migrated to those systems in the first quarter of 1999.
Additionally, the Company is developing plans to upgrade or replace the existing
operational systems with compliant versions. This remediation effort is expected
to be completed by the end of the third quarter of 1999. The failure to upgrade
the Myrtle Beach operational systems to a compliant version could have a
material adverse effect on the Company.

   Initial assessments of our Information Technology have shown that our network
hardware, software and firmware was procured and deployed at a compliant version
level. Some previously deployed Information Technology hardware in the Myrtle
Beach markets is non-compliant. However, these non-compliant applications are
planned for upgrade, and given the nature of the Company's operations, potential
failures of these applications are not expected to have a material adverse
effect on the Company.

   The Company has not yet fully developed a comprehensive contingency plan to
address situations that may result if the Company is unable to achieve Year 2000
readiness of its critical operations.  There can be no assurance that the
Company will be able to develop a contingency plan that will adequately address
issues that may arise in the year 2000.  The failure of the Company to
successfully resolve such issues could result in a disruption of the Company's
service and operations, which would have a material adverse effect on the
Company.

   The costs associated with the Year 2000 issues are estimated to be
approximately $200,000, of which $48,000 has been spent to date. These costs are
not material to the Company's business operations or financial position. The
costs of the plan and the date on which the Company believes it will complete
the Year 2000 modification are based on management's best estimates, which were
derived utilizing numerous assumptions regarding future events, including the
continued availability of certain resources, third-party modification plans and
other factors. There can be no assurance that these estimates will be achieved
and actual results could differ materially from those anticipated.

INFLATION

   The Company does not believe that inflation has had a material impact on
operations.

ITEM 7A  Quantitative and Qualitative Disclosure about Market Risk

   The Company's debt structure is leveraged and, as a result, its cash flows
and earnings are exposed to fluctuations in interest rates. The Company's debt
obligations are U.S. dollar denominated. The Company's market risk therefore is
the potential loss arising from adverse changes in interest rates. The debt can
be categorized as follows:

   Fixed interest rates:
           Senior subordinated debt         $313,648

   Subject to interest rate fluctuations:
           Bank credit facility             $150,000


   The Company's interest rate risk management program focuses on minimizing 
exposure to interest rate movements, setting an optional mixture of floating and
fixed rate debt, and minimizing liquidity risk. (see Note 12 to Notes to the 
Combined Financial Statements).

standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the combined financial statements referred to above present
fairly, in all material respects, the financial position of Triton PCS, Inc. and
predecessor company as of December 31, 1998 and 1997, and the results of their
operations and their cash flows for the year ended December 31, 1998 and the

generally accepted accounting principles. Also in our opinion, the related 
financial statement schedule, when considered in relation to the basic combined 
financial statements taken as a whole, presents fairly, in all material 
respects, the information set forth therein.

                    NOTES TO COMBINED FINANCIAL STATEMENTS
      FOR THE PERIOD FROM MARCH 6, 1997 (INCEPTION) TO DECEMBER 31, 1998


(1)  DESCRIPTION OF BUSINESS

     Triton PCS, Inc. (formerly Triton PCS License Company, Inc. with its
     subsidiaries referred to as the "Company") was formed on October 2, 1997 as
     a wholly-owned subsidiary of Triton PCS Holdings, Inc. (formerly Triton
     PCS, Inc. referred to as "Holdings" or "Parent"). The Company is the
     exclusive provider of wireless mobility services in the AT&T Corporation
     (together with affiliates "AT&T") mid-Atlantic and southeast regions.  The
     Company intends to become the leading provider of broadband PCS in
     Virginia, South Carolina, North Carolina, northern Georgia, and surrounding
     areas.  The Company is authorized to provide PCS Service in major
     population and business centers such as Charleston, SC, Columbia, SC,
     Greenville / Spartansburg, SC, Richmond, VA and Augusta, GA, as well as
     major resort destinations such as Myrtle Beach, SC, Hilton Head, SC, and
     Kiawah Island, SC.  On June 30, 1998, the Company acquired an existing
     cellular system in Myrtle Beach, and on December 31, 1998, the Company
     extended its PCS Service into the Norfolk, Virginia BTA through the
     acquisition of licenses and assets from AT&T (see note 4).


(2)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     BASIS OF PRESENTATION

     On March 6, 1997, Triton Communications L.L.C. ("L.L.C.") was formed to
     explore various business opportunities in the wireless telecommunications
     industry, principally related to personal communications services ("PCS")
     and cellular activities.  During the period March 6, 1997 through October
     1, 1997, L.L.C.'s activities consisted principally of hiring a management
     team, raising capital, and negotiating strategic business relationships,
     primarily related to PCS business opportunities.  Subsequent to October 2,
     1997, these activities continued but were conducted primarily through the
     Company.  Consequently, for purposes of the accompanying financial
     statements, L.L.C. has been treated as a "predecessor" entity. As a result
     of certain financing relationships and the similar nature of the business
     activities conducted by each respective legal entity, L.L.C. and the
     Company are considered companies under common control.

     The combined financial statements incorporate the PCS-related business
     activities of L.L.C. and the activities of the Company.  The consolidated
     accounts of the Company include Triton PCS Inc.; Triton PCS Holdings
     Company L.L.C.; Triton Management Company, Inc.; Triton PCS Property
     Company L.L.C.; Triton PCS Equipment Company L.L.C.; Triton PCS Operating
     Company L.L.C.; and Triton PCS License Company L.L.C.  All significant
     intercompany accounts or balances have been eliminated in consolidation.

     USE OF ESTIMATES

     The preparation of financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the reported amounts of assets and liabilities and
     disclosure of contingent assets and liabilities, at the date of the
     financial statements and the reported amount of revenues and expenses
     during the reporting period.  Actual results could differ from those
     estimates.

     CASH AND CASH EQUIVALENTS

     Cash and cash equivalents includes cash on hand, demand deposits and short
     term investments with maturities of three months or less.

                    NOTES TO COMBINED FINANCIAL STATEMENTS
      FOR THE PERIOD FROM MARCH 6, 1997 (INCEPTION) TO DECEMBER 31, 1998


     MARKETABLE SECURITIES

     Marketable securities at December 31, 1998, consist of debt securities with
     maturities between three and ten months.  The Company has adopted the
     provisions of Statement of Financial Accounting Standards No. 115,
     "Accounting for Certain Investments in Debt and Equity Securities"
     ("Statement No. 115") in fiscal 1998.  Under Statement No. 115, the Company
     classifies all of its debt securities as available for sale and records
     them at fair value with unrealized holding gains and losses to be included
     as a separate component of other comprehensive income until realized.
     Realized gains and losses from the sale of available for sale securities
     are determined on the specific identification basis.

     INVENTORIES

     Inventories, consisting primarily of wireless handsets and accessories held
     for resale, are valued at lower of cost or market.  Cost is determined by
     the first-in, first-out method.

     PROPERTY AND EQUIPMENT

     Property and equipment is stated at original cost and includes primarily
     computer equipment, software, and office equipment.  Depreciation is
     calculated based on the straight-line method over the estimated useful
     lives of the respective assets.  In connection with the construction of the
     PCS network, the Company capitalizes expenditures related to the design,
     construction, and microwave relocation.  In addition, the Company
     capitalizes interest on expenditures related to the buildout of the
     network.  Expenditures for repairs and maintenance are charged to expense
     as incurred.

     CONSTRUCTION IN PROGRESS

     Construction in progress includes expenditures for the design, construction
     and testing of the Company's PCS network and also includes costs associated
     with developing information systems.  The Company capitalizes interest on
     certain of its construction in progress activities.  Interest capitalized
     for the year ended December 31, 1998 totaled $3.5 million.  When the assets
     are placed in service, the Company transfers the assets to the appropriate
     property and equipment category and depreciates these assets over their
     respective estimated useful lives.

     INVESTMENT IN PCS LICENSES

     Investments in PCS Licenses are recorded at their estimated fair value at
     the time of acquisition (See Notes 3 and 4). Licenses are amortized on a
     straight line basis over 40 years.

     DEFERRED TRANSACTION COSTS

     Costs incurred in connection with the negotiation and documentation of the
     AT&T transaction, are deferred and included in the aggregate purchase price
     allocated to the net assets acquired upon completion of the transaction.

     Costs incurred in connection with the negotiation and documentation of the
     bank financing and the Company's issuance of senior subordinated discount
     notes are deferred and amortized over the terms of the bank financing and
     notes using the effective interest rate method.

      FOR THE PERIOD FROM MARCH 6, 1997 (INCEPTION) TO DECEMBER 31, 1998

     LONG-LIVED ASSETS

     In accordance with SFAS No. 121, "Accounting for the Impairment of Long-
     Lived Assets and for Long-Lived Assets to be Disposed Of," the Company
     periodically evaluates the carrying value of long-term assets when events
     and circumstances warrant such review. The carrying value of a long lived
     asset is considered impaired when the anticipated undiscounted cash flow
     from such asset is separately identifiable and is less than the carrying
     value. In that event a loss is recognized based on the amount by which the
     carrying value exceeds the fair market value of the long lived asset. Fair
     market value is determined by using the anticipated cash flows discounted
     at a rate commensurate with the risk involved. Measurement of the
     impairment, if any, will be based upon the difference between carrying
     value and the fair value of the asset. The Company has identified no such
     impairment losses.

     REVENUE RECOGNITION

     Revenues from operations primarily consist of charges to customers for
     monthly access, airtime, roaming charges, long-distance charges, and
     equipment sales.  Revenues are recognized as services are rendered net of
     sales allowance.  Unbilled revenues result from service provided from the
     billing cycle date to the end of the month and from other carrier's
     customers using the Company's systems for the last half of each month.
     Equipment sales are recognized upon delivery to the customer and reflect
     charges to customers for wireless handset equipment purchases.

     INCOME TAXES

     The Company accounts for income taxes in accordance with Statement of
     Financial Accounting Standards ("SFAS") No. 109, "Accounting for Income
     Taxes".  Under the asset and liability method of SFAS No. 109, deferred
     income tax assets and liabilities are recognized for the future tax
     consequences attributable to differences between the financial statement
     carrying amounts of existing assets and liabilities and their respective
     tax bases.  Deferred income tax assets and liabilities are measured using
     statutory tax rates expected to apply to taxable income in the years in
     which those temporary differences are expected to be recovered or settled.

     FINANCIAL INSTRUMENTS

     The Company utilized derivative financial instruments to reduce its
     exposure resulting from fluctuations in interest rates.  Amounts to be paid
     or received under interest rate swap agreements are accrued as interest
     rates change and are recognized over the life of the swap agreements as an
     adjustment to interest expense.

      FOR THE PERIOD FROM MARCH 6, 1997 (INCEPTION) TO DECEMBER 31, 1998


     ADVERTISING COSTS

     The Company expenses advertising costs when the advertisement occurs.
     Total advertising expense amounted to $643,000 in 1998.

     COMPREHENSIVE INCOME (LOSS)

     The Company adopted Statement of Financial Accounting Standard No. 130,
     "Reporting Comprehensive Income" (SFAS 130), effective January 1, 1998.
     SFAS 130 establishes standards for reporting and display of comprehensive
     income and its components in a full set of general-purpose financial
     statements.  Comprehensive income is the change in equity of a business
     enterprise during a period from certain transactions and the events and
     circumstances from non-owner sources.  For the periods presented in the
     accompanying combined statements of operations, comprehensive loss equals
     the amounts of net loss reported on the accompanying  combined statements
     of operations.

     NEW ACCOUNTING PRONOUNCEMENTS

     In April 1998, the Accounting Standards Executive Committee (AcSEC) of the
     AICPA issued Statement of Position (SOP) 98-5, Reporting on the Costs of
     Start-up Activities ("SOP 98-5").  This statement requires that the costs
     of start-up activities, including organization costs, be expensed as
     incurred and is effective for fiscal years beginning after December 31,
     1998.  The Company has elected early adoption of this statement as of
     January 1, 1998.  The initial application of the statement did not have a
     material effect on the Company's combined financial statements.

     In June 1997, the FASB issued Statement No. 131, "Disclosure About Segments
     of an Enterprise and Related Information" ("SFAS 131").  This statement
     establishes additional standards for segment reporting in the financial
     statements and is effective for fiscal years beginning after December 15,
     1997.  The Company adopted SFAS 131 and determined that there are no
     separate reportable segments, as defined by the standards.

     In June 1998, the FASB issued Statement No. 133, "Accounting for Derivative
     Instruments and Hedging Activities ("SFAS 133") which establishes
     accounting and reporting standards for derivative instruments, including
     certain derivative  instruments imbedded in other contracts and for hedging
     activities.  SFAS 133 is effective for fiscal years beginning after June
     15, 1999.  The initial application of this statement is not expected to
     have a material effect on the Company's financial statements.


(3)  AT&T TRANSACTION

     On October 8, 1997, Holdings entered into a Securities Purchase Agreement
     with AT&T Wireless PCS, Inc, a subsidiary of AT&T Corp.,and the other
     stockholders of Holdings, whereby the Company became the exclusive provider
     of wireless mobility services in the AT&T Southeast regions.

     On February 4, 1998, Holdings executed the Closing Agreement with AT&T and
     the other stockholders of Holdings, finalizing the transactions
     contemplated in the Securities Purchase Agreement. In accordance with the
     Closing Agreement, Holdings and AT&T and the other stockholders of Holdings
     consented that one or more of Holdings' subsidiaries shall enter into
     certain agreements or conduct certain operations on the condition that such
     subsidiaries shall at all times be direct or indirect wholly-owned
     subsidiaries of Holdings and Holdings shall cause such subsidiaries to
     perform the obligations and conduct such operations required to be
     performed or conducted under those agreements.

                    NOTES TO COMBINED FINANCIAL STATEMENTS
      FOR THE PERIOD FROM MARCH 6, 1997 (INCEPTION) TO DECEMBER 31, 1998


     Under the Closing Agreement, Holdings issued equity to AT&T in exchange for
     20 MHz A and B Block PCS licenses, which were contributed to the Company
     and certain other agreements covering certain areas in the southeastern
     United States. The fair value of the FCC licenses, as determined by an
     independent appraisal, was $92.8 million with an estimated useful life of
     40 years.

     In connection with the closing of the AT&T transaction, the Company
     executed or was a party to certain agreements, including the following:


     STOCKHOLDERS' AGREEMENT

     Resale Agreement

     Pursuant to the Stockholders' Agreement, the Company is required to enter
     into a Resale Agreement at the request of AT&T. Under this agreement, AT&T
     will be granted the right to purchase and resell on a nonexclusive basis
     access to and usage of the Company's services in the Company's Licensed
     Area. The Company will retain the continuing right to market and sell its
     services to customers and potential customers in competition with AT&T.

     The Resale Agreement will have a term of ten years and will renew
     automatically for successive one-year periods unless, after the eleventh
     anniversary thereof, either party elects to terminate the Resale Agreement.
     Furthermore, AT&T may terminate the Resale Agreement at any time for any
     reason on 180 days written notice.

     The Company has agreed that the rates, terms, and conditions of service,
     taken as a whole, provided by the Company to AT&T pursuant to the Resale
     Agreement, shall be at least as favorable as (or if permitted by applicable
     law, superior to) the rates, terms, and conditions of service, taken as a
     whole, provided by the Company to any other customer. Without limiting the
     foregoing, the rate plans offered by the Company pursuant to the Resale
     Agreement shall be designed to result in a discounted average actual rate
     per minute paid by AT&T for service below the weighted average actual rate
     per minute billed by the Company to its subscribers generally for access
     and air time.

     Neither party may assign or transfer the Resale Agreement or any of its
     rights thereunder without the other party's prior written consent, which
     will not be unreasonably withheld, except (a) to an affiliate of that party
     at the time of execution of the Resale Agreement, (b) by the Company to any
     of its operating subsidiaries, and (c) to the transferee of a party's stock
     or substantially all of its assets, provided that all FCC and other
     necessary approvals have been received.

     The Company expects to enter into the Resale Agreement upon commencement of
     its operations in the initial configuration or shortly thereafter.

     Exclusivity

     Under the Stockholders' Agreement, none of the Stockholders will provide or
     resell, or act as the agent for any person offering, within the Territory
     mobile wireless telecommunications services initiated or terminated using
     Time Division Multiple Access and frequencies licensed by the FCC ("Company
     Communications Services"), except AT&T and its affiliates may (i) resell or
     act as agent for the Company in connection with the provision of Company
     Communications Services, (ii) provide or resell wireless telecommunications
     services to or from certain specific locations, and (iii) resell Company
     Communications Services for another person in any area where the Company
     has not placed a system into commercial service, provided that AT&T PCS has
     provided the Company with prior written notice of

      FOR THE PERIOD FROM MARCH 6, 1997 (INCEPTION) TO DECEMBER 31, 1998


     AT&T PCS' intention to do so and only dual band/dual mode phones are used
     in connection with such resale activities . Additionally, with respect to
     the markets listed in the Roaming Agreement, each of the Company and AT&T
     agreed to cause their respective affiliates in their home carrier
     capacities to program and direct the programming of customer equipment so
     that the other party in its capacity as the serving carrier is the
     preferred provider in such markets, and refrain from inducing any of its
     customers to change such programming.

     Build-out

     The Company is required to conform to certain requirements regarding the
     construction of the Company's PCS system. In the event that the Company
     breaches these requirements, AT&T may terminate its exclusivity provisions.

     Disqualifying Transactions

     In the event of a merger, asset sale, or consolidation, as defined,
     involving AT&T and another person that derives annual revenues in excess of
     $5.0 billion, derives less than one third of its aggregate revenues from
     wireless telecommunications, and owns FCC licenses to offer mobile wireless
     telecommunication services to more than 25% of the population within the
     Company's territory, AT&T and the Company have certain rights. AT&T may
     terminate its exclusivity in the territory in which the other party
     overlaps that of the Company. In the event that AT&T proposes to sell,
     transfer, or assign to a non-affiliate its PCS system owned and operated in
     Charlotte, NC; Atlanta, GA; Baltimore, MD; and Washington, DC, BTAs, then
     AT&T will provide the Company with the opportunity for a 180 day period to
     have AT&T jointly market the Company's licenses that are included in the
     MTA that AT&T is requesting to sell.

     The Stockholders' Agreement expires on February 4, 2009. Certain provisions
     expire upon an initial public offering.

     LICENSE AGREEMENT

     Pursuant to a Network Membership License Agreement, dated February 4, 1998
     (the "License Agreement"), between AT&T and the Company, AT&T granted to
     the Company a royalty-free, nontransferable, nonsublicensable, limited
     right, and license to use certain Licensed Marks solely in connection with
     certain licensed activities. The Licensed Marks include the logo containing
     the AT&T and globe design and the expression "Member, AT&T Wireless
     Services Network." The "Licensed Activities" include (i) the provision to

     Commercial Mobile Radio Services ("CMRS") provided in accordance with the
     AT&T Agreement (collectively, the "Licensed Services") and (ii) marketing
     and offering the Licensed Services within the Territory. The License
     Agreement also grants to the Company the right and license to use Licensed
     Marks on certain permitted mobile phones.

     The License Agreement contains numerous restrictions with respect to the
     use and modification of any of the Licensed Marks. Furthermore, the Company
     is obligated to use commercially reasonable efforts to cause all Licensed
     Services marketed and provided using the Licensed Marks to be of comparable
     quality to the Licensed Services marketed and provided by AT&T and its
     affiliates in areas that are comparable to the Territory taking into
     account, among other things, the relative stage of development of the
     areas. The License Agreement also sets forth specific testing procedures to
     determine compliance with these standards, and affords the Company with a
     grace period to cure any instances of alleged noncompliance therewith.

     The Company may not assign or sublicense any of its rights under the
     License Agreement; provided, however, that the License Agreement may be
     assigned to the Company's lenders under the Credit Facility (see note 9)
     and after the expiration of any applicable grace and cure periods under the
     Credit Facility, such lenders may enforce the Company's rights under the
     License Agreement and assign the License Agreement to any person with
     AT&T's consent.

     The term of the License Agreement is for five years (the "Initial Term")
     and renews for an additional five-year period if neither party terminates
     the Agreement. The License Agreement may be terminated by AT&T at any time
     in the event of a significant breach by the Company, including the
     Company's misuse of any Licensed Marks, the Company licensing or assigning
     any of the rights in the License Agreement, the Company's failure to
     maintain AT&T's quality standards, or a change in control of the Company
     occurs.

     After the Initial Term, AT&T may also terminate the License Agreement upon
     the occurrence of certain transactions described in the Stockholders'
     Agreement.

     The License Agreement, along with the Exclusivity and Resale Agreements,
     have a fair value of $20.3 million, as determined by an independent
     appraisal, with an estimated useful life of 10 years.   Amortization
     commenced upon the effective date of the agreement.

     ROAMING AGREEMENT

     Pursuant to the Intercarrier Roamer Service Agreement, dated as of February
     4, 1998 (as amended the "Roaming Agreement"), between AT&T Wireless
     Services, Inc. and the Company, each of AT&T and the Company agrees to
     provide (each in its capacity as serving provider, the "Serving Provider")
     mobile wireless radiotelephone service for registered customers of the
     other party's (the "Home Carrier") customers while such customers are out
     of the Home Carrier's geographic area and in the geographic area where the
     Serving Carrier (itself or through affiliates) holds a license or permit to
     construct and operate a mobile wireless radio/telephone system and station.
     Each Home Carrier whose customers receive service from a Serving Carrier
     shall pay to such Serving Carrier 100% of the Serving Carrier's charges for
     wireless service and 100% of pass-through charges (i.e., toll or other
     charges).   Except with respect to the Norfolk BTA, each Service Carrier's
     service charges per minute or partial minute for the first 3 years will be
     fixed at a declining rate, and thereafter will be equal to an adjusted
     average home rate or such lower rate as the parties negotiate from time to
     time; provided, however, that with respect to the Norfolk BTA, the service
     rate is equal to the lesser of (a) $0.25 per minute and (b) the applicable
     home rate of AT&T PCS, or such other rate as agreed to by the parties.
     Each Service Carrier's toll charges per minute of use for the first 3 years
     will be fixed at a declining rate and thereafter, such other rates as the
     parties negotiate from time to time.

     The Roaming Agreement has a term of 20 years, unless earlier terminated by
     a party due to the other party's uncured breach of any term of the Roaming
     Agreement, the other party's license or permit to provide CMRS.

     Neither party may assign or transfer the Roaming Agreement or any of its
     rights thereunder except to an assignee of all or part of its license or
     permit to provide CMRS, provided that such assignee expressly assumes all
     or the applicable part of the obligations of such party under the Roaming
     Agreement.

     The fair value of the Roaming Agreement, as determined by an independent
     appraisal, was $5.5 million, with an estimated useful life of 20 years.
     Amortization commenced upon the effective date of  the agreement.

(4)  ACQUISITIONS

     Myrtle Beach Acquisition
     ------------------------

     On June 30, 1998, the Company acquired an existing cellular system (the
     "Myrtle Beach System") which serves the South Carolina 5--Georgetown Rural
     Service Area (the "SC-5") for a purchase price of approximately $164.5
     million from Vanguard Cellular Systems. The Company has integrated the
     Myrtle Beach System into its planned PCS Network. As a result of the
     acquisition, the Company is no longer considered a development stage
     enterprise under SFAS No. 7. The effects of the acquisition have been
     presented using the purchase method and, accordingly, the purchase price
     was allocated to the assets acquired and liabilities assumed based upon
     management's best estimate of their fair value.

     The purchase price was allocated to the net assets acquired with
     approximately $116 million allocated to Licenses with a useful life of 40
     years and approximately $20 million allocated to Subscriber List with a
     useful of 5 years.

     Results of operations after the acquisition date are included in the
     Statement of Operations from July 1, 1998.  The following  unaudited pro
     forma information has been prepared assuming that this acquisition had
     taken place on January 1, 1997.  The pro forma information includes
     adjustments to interest expense that would have been incurred to finance
     the purchase, additional depreciation based on the fair market value of the
     property, plant and equipment acquired, and the amortization of intangibles
     arising from the transaction.

     Norfolk Acquisition

     On December 31, 1998, the Company acquired from AT&T (the "Norfolk
     Acquisition") (i) an FCC license to use 20MHz of authorized frequencies to
     provide broadband PCS services throughout the entirety of the Norfolk,
     Virginia BTA and (ii) certain assets of AT&T used in the operation of the
     PCS system in such BTA for an aggregate purchase price of approximately
     $111 million, including $14.6 million of Series D Preferred Stock of
     Holdings, which was subsequently contributed to the Company. The excess of
     the aggregate purchase price over the fair market value of tangible net
     assets acquired of approximately $46.3 million is attributed to licenses
     and is being amortized over 40 years. The build-out of the network relating
     to the Norfolk Acquisition, including the installation of a switch, has
     been substantially completed. The Company has commenced PCS service in the
     Norfolk BTA in the first quarter 1999. The purchase price allocation is
     preliminary at December 31, 1998 and is expected to be finalized in the
     first quarter of 1999.

(7)  SHORT-TERM DEBT

     Convertible Notes

     At various dates in 1997, certain private equity investors provided $1.6
     million in financing to L.L.C. in the form of convertible promissory notes.
     The notes originally bore interest at 14% annually, payable at maturity. On
     January 15, 1998, L.L.C. assigned the notes to the Company. The Company, in
     conjunction with Holdings and the noteholders, subsequently negotiated a
     revised arrangement under which no interest

     would be paid on the notes, which became convertible into approximately
     $3.2 million worth of Holdings' Series C preferred stock. The conversion of
     L.L.C. notes into Holdings equity occurred on February 4, 1998. The $1.6
     million preferred return to the investors was accounted for as a financing
     cost during the period the notes were outstanding.

     Noninterest bearing loans

     During 1997, Holding's Cash Equity Investors provided short-term financing
     in the form of $11.8 million noninterest-bearing loans, which were advanced
     to the Company. Pursuant to the Closing Agreement, such loans were
     converted to equity of Holdings as a reduction of the requirements of the
     initial cash contribution. Concurrently, Holdings contributed these funds
     to the Company, which has recorded the transaction as additional paid in
     capital on the date of the contribution.

(9)  BANK CREDIT FACILITY

     On February 3, 1998, (the "Credit Facility Effective Date"), the Company
     entered into a Credit Agreement (as amended from time to time, the "Credit
     Facility"), with Holdings, The Chase Manhattan Bank, as Administrative
     Agent, and certain banks and other financial institutions party thereto.
     The Credit Facility provides for (i) a $175.0 million senior secured term
     loan (the "Tranche A Term Loan") which may be drawn in installments at any
     time through the third anniversary of the Credit Facility Effective Date
     and matures on the date that is eight and one-half years from the credit
     Facility Effective Date, (ii) a $150.0 million senior secured term loan
     (the "Tranche B Term Loan" and, together with the Tranche A Term Loan, the
     "Term Loans") which matures on the date that is nine and one-quarter years
     from the "Credit Facility Effective Date," and (iii) a $100.0 million
     senior secured revolving credit facility (the "Revolving Credit Facility"
     and, together with the commitments to make the Term Loans, the
     "Facilities") which matures on the date that is eight and one-half years
     from the Credit Facility Effective Date.

     The commitment to make loans under the Revolving Credit Facility
     ("Revolving Credit Loans" and, together with the Term Loans, the "Loans")
     automatically and permanently reduces, beginning on the date that is six
     years and six months after the Credit Facility Effective Date, in eight
     quarterly reductions (the amount of each of the first two reductions, $5.0
     million, the next four reductions, $10.0 million, and the last two
     reductions, $25.0 million). The Tranche A Term Loans are required to be
     repaid, beginning on the date that is four years after the Credit Facility
     Effective Date, in eighteen consecutive quarterly installments (the amount
     of each of the first four installments, $4,375,000, the next four
     installments, $6,562,500, the next four installments $8,750,000, the next

     $375,000, the next four installments $7.5 million, and the last
     installment, $114.0 million).

     Interest on all loans accrue, at the Company's option, either at (i) (a) a
     LIBOR rate, a defined in the Credit Facility plus (b) the Applicable Rate
     (as defined below) (Loans bearing interest described in (i), "Eurodollar
     Loans") or (ii) (a) the higher of (1) the Administrative Agent's prime rate
     and (2) the Federal Funds Effective Rate (as defined in the Credit
     Facility) plus 0.5%, plus (b) the Applicable Rate (Loans bearing interest
     described in (ii), "ABR Loans"). Interest on any overdue amounts will be at
     a rate per annum equal to 2% plus the rate otherwise applicable to such
     amounts. The Applicable Rate means, with respect to Tranche B Term Loans,
     1.75% per annum, in the case of an ABR Loan, and 3.00% per annum, in the
     case of a Eurodollar Loan, and, with respect to Tranche A Term Loans and
     Revolving Credit Loans, a rate between 0.0% to 1.25% per annum (depending
     on the level of the Company's ratio of debt to earnings before income
     taxes, depreciation, and amortization (EBITDA) in the case of an ABR Loan,
     and a rate between 1.00% and 2.25% per annum (depending on the level of the
     Company's ratio of debt to EBITDA), in the case of a Eurodollar Loan.

     The Credit Facility requires an annual commitment fee of between 0.375% and
     0.50% (depending on the level of the Company's ratio of debt to EBITDA) of
     the unused portion of the Facilities payable quarterly in arrears and a
     separate agent's fee payable to the Administrative Agent. The Credit
     Facility also requires the Company to fix or limit the interest cost with
     respect to at least 60% (as amended in  July 1998) of the total amount of
     the outstanding indebtedness of the Company.  The Company incurred
     commitment fees of $2.0 million in 1998.  At December 31, 1998,
     approximately 84% of the Company's outstanding debt was fixed.

     The Term Loans are required to be prepaid and commitments under the
     Revolving Credit Facility reduced in an aggregate amount equal to (i) 50%
     of excess cash flow of each fiscal year commencing the fiscal year ending
     December 31, 2001, (ii) 100% of the net proceeds of asset sales, in excess
     of a yearly threshold, outside the ordinary course of business or unused
     insurance proceeds, (iii) 100% of the net cash proceeds in excess of the
     initial $150.0 million of issuances of debt obligations and (iv) 50% of the
     net cash proceeds of issuances of equity securities (other than in
     connection with the Equity Commitments); provided, that the prepayments and
     reductions set forth under clauses (iii) and (iv) will not be required if,
     after giving effect to such issuance, (a) the Company's ratio of senior
     debt to EBITDA would be less than 5 to 1 and (b) the Company would be in
     pro forma compliance with certain covenants in the Credit Facility.

     All obligations of the Company under the Facilities are unconditionally and
     irrevocably guaranteed (the "Bank Facility Guarantees") by Holdings and
     each existing and subsequently acquired or organized domestic subsidiary of
     the Company. The Facilities and the Bank Facility Guarantees, and any
     related hedging contracts provided by the lenders under the Credit
     Facility, are secured by substantially all of the assets of the Company and
     each existing and subsequently acquired or organized domestic subsidiary of
     the Company, including a first priority pledge of all of the capital stock
     held by the Company or any of its subsidiaries; provided that the pledge of
     shares of foreign subsidiaries may be limited to 65% of the outstanding
     shares of such foreign subsidiaries. The PCS Licenses will be held by one
     or more single purpose subsidiaries of the Company and will not be pledged
     to secure the obligations of the Company under the Credit Facility,
     although the equity interests of such subsidiaries will be pledged
     thereunder. Each single purpose subsidiary will not be allowed by the
     Company to incur any liabilities or obligations other than the Bank
     Facility Guarantee issued by it, the security agreement entered into by it
     in connection with the Credit Facility, and, in the case of any single
     purpose subsidiary established to hold real estate, liabilities incurred in
     the ordinary course of business of such subsidiary which are incident to
     being the lessee of real property of the purchaser, owner of lessee of
     equipment and taxes and other liabilities incurred in the ordinary course
     in order to maintain its existence.

                   TRITON PCS, INC. AND PREDECESSOR COMPANY 
                    NOTES TO COMBINED FINANCIAL STATEMENTS
      FOR THE PERIOD FROM MARCH 6, 1997 (INCEPTION) TO DECEMBER 31, 1998


     The Credit Facility contains covenants customary for facilities and
     transactions similar to the Credit Facility, including covenants relating
     to the amounts of indebtedness that the Company may incur, limitations on
     dividends and distributions on, and redemptions and repurchases of, capital
     stock and other similar payments and various financial maintenance
     covenants. The Credit Facility also contains covenants relating to the
     population covered by the Company's network and number of customers and
     customary representations, warranties, indemnities, conditions precedent to
     borrowing, and events of default.

     Loans under the Credit Facility are available to fund capital expenditures
     related to the construction of the Company's PCS network, the acquisition
     of related businesses, working capital needs of the Company, and customer
     acquisition costs. All indebtedness under the Credit Facility will
     constitute Senior Debt under the Company's 11% Senior Subordinated Discount
     Notes.

     The terms of the Credit Facility originally allowed the Company to incur
     only $150 million of indebtedness pursuant to the issuance of Subordinated
     Debt (as defined in the Credit Facility). In April 1998, the Company
     negotiated an amendment to the Credit Facility, which included provisions
     that (i) permit certain acquisitions (note 4); (ii) permit up to a total of
     $450 million in high yield debt; and (iii) exclude the equity issuances
     associated with certain acquisitions from the mandatory prepayment
     requirement.
     
(10) SUBORDINATED DEBT

     On May 7, 1998, the Company completed an offering (the "Offering") of $512
     million of 11% Senior Subordinated Discount Notes ("the Notes"), pursuant
     to Rule 144A of the Securities Act of 1933, as amended. The net proceeds of
     the Offering (after deducting an Initial Purchaser's Discount of $9
     million) were approximately $291 million. The Company has used and intends
     to use the net proceeds from the Offering, together with the Capital
     Contributions (note 15) and borrowings under the Credit Facility, to fund:
     (i) capital expenditures, including the build-out of its PCS network; (ii)
     the Myrtle Beach acquisition and the Norfolk acquisition (note 4); (iii)
     working capital as required; (iv) operating losses; (v) general corporate
     purposes, and (vi) potential acquisitions.

     Cash interest will not accrue prior to May 1, 2003.  Commencing on November
     1, 2003, cash interest will be payable semiannually.  Each Note was offered
     at an original issue discount (Initial Purchaser's Discount).  Although
     cash interest will not be paid prior to May 1, 2003, the original issue
     discount will accrue from the issue date to May 1, 2003.

     The Notes are not redeemable prior to May 1, 2003, except as set forth
     below.  The Notes will be redeemable at the option of the Company, in whole
     or in part, at any time on or after May 1, 2003 and prior to maturity at
     the following redemption prices (expressed as percentages of principal
     amount), plus accrued interest, if any, up to but excluding the redemption
     date, if redeemed during the 12-month period beginning on May 1 of the
     years indicated:

</TABLE>

     In addition, on or prior to May 1, 2001, the Company may redeem up to 35%
     of the principal amount at maturity of Notes issued under the Indenture at
     a redemption price equal to 111% of the accreted value at the redemption
     date with the net proceeds of one or more equity offerings of qualified
     stock of (a) the Company, (b) Holdings, or (c) a special purpose
     corporation formed to own qualified stock of the Company

     or Holdings, provided that at least 65% of the aggregate principal amount
     at maturity of Notes issued under the Indenture would remain outstanding
     immediately after giving effect to such redemption.

     Upon a change in control, each holder of the Notes may require the Company
     to repurchase such Holder's Notes, in whole or in part, at a purchase price
     equal to 101% of the accreted value thereof or the principal amount at
     maturity, as applicable plus accrued and unpaid interest to the purchase
     date.  

     The debt principal begins to mature in 2003 and is fully repaid in 2008.

     In assessing the realizability of deferred tax assets, management considers
     whether it is more likely than not that some portion or all of the deferred
     tax assets will not be realized.  The ultimate realization of deferred tax
     assets is dependent upon the generation of future taxable income during the
     periods in which those

     temporary differences become deductible. Because the Company does not have
     an operating history, management has only considered the scheduled reversal
     of deferred tax liabilities and tax planning strategies in making this
     assessment. Based upon the assessment, management believes it is more
     likely than not the Company will realize the benefits of the deferred tax
     assets, net of the existing valuation allowance at December 31, 1998. The
     Company recorded a Deferred tax liability of $17,771 in connection with the
     contribution of licenses pursuant to the AT&T Transaction (note 3).


(12) FAIR VALUE OF FINANCIAL INSTRUMENTS

     Fair value estimates, assumptions, and methods used to estimate the fair
     value of the Company's financial instruments are made in accordance with
     the requirements of Statement of Financial Accounting Standards No. 107,
     "Disclosures about Fair Value of Financial Instruments."  The Company has
     used available market information to derive its estimates.  However,
     because these estimates are made as of a specific point in time, they are
     not necessarily indicative of amounts the Company could realize currently.
     The use of different assumptions or estimating methods may have a material
     effect on the estimated fair value amounts.

     term loan, and capital leases.  The fair value of subordinated debt is
     stated at quoted market value.  The carrying amount of the bank term loan
     is a reasonable estimate of its fair value.  Capital leases are recorded at
     their net present value, which approximates fair value.

      FOR THE PERIOD FROM MARCH 6, 1997 (INCEPTION) TO DECEMBER 31, 1998 

 
     INTEREST RATE RISK MANAGEMENT AGREEMENTS - The Company enters into interest
     rate protection agreements to lock in interest rates on the variable
     portion of its debt. The Company does not use these agreements for trading
     or other speculative purposes, nor is it a party to any leveraged
     derivative instrument.  Although these agreements are subject to
     fluctuations in value, they are generally offset by fluctuations in the
     value of the underlying instrument or anticipated transaction.

     In an interest rate swap, the Company agrees to exchange, at specified
     intervals, the difference between a variable interest rate (based on 3
     month Libor) and either a fixed or another variable interest rate
     calculated by reference to an agreed-upon notional principal amount. The
     resulting rate differential is reflected as an adjustment to interest
     expense over the life of the swap. The Company did not exercise this swap
     during 1998; at December 31, 1998, the Company would receive $23,000 to
     settle these agreements.

     The following table summarizes the Company's off-balance sheet interest
     rate swap agreements at December 31, 1998:

shares, 398,000 shares, 99,000 shares, 50,000 shares and 50,000 shares,
respectively, of Series C preferred stock, and Michael Kalogris and Steven
Skinner have severally made irrevocable commitments to contribute to Holdings
$500,000 and $250,000, respectively, in cash in exchange for 5,000 shares and
2,500 shares, respectively, of Series C preferred stock. The Cash Equity
Investors, together with the Management Stockholders, have contributed an
aggregate of $80 million of their $140 million commitment as of December 31,
1998. The Cash Equity Investors and the Management Stockholders are required to
contribute the unfunded portion of their respective commitments under the
securities purchase agreement (the "Unfunded Commitment Amount") to Holdings on
the second, and third anniversary dates of the securities purchase closing
Date. Each Cash Equity Investor's obligation to make capital contributions to
Holdings after the securities purchase closing Date in respect of its unfunded
commitment amount is (i) an unconditional and irrevocable obligation, and is not
subject to counterclaim, set-off, deduction or defense, or to abatement,
suspension, deferment, diminution or reduction for any reason whatsoever and
(ii) secured by a pledge of all shares of Series C preferred stock issued to
such party under the securities purchase agreement pursuant to a pledge
agreement between Holdings and such party.


THE MYRTLE EQUITY CONTRIBUTION

  Pursuant to a preferred stock purchase agreement, dated as of June 29, 1998,
Holdings received additional equity contributions of approximately $10.2
million, $10.0 million, $9.8 million, $2.5 million, $1.2 million and $1.2
million, respectively, from Chase Capital Partners, J.P. Morgan Investment
Corporation, Desai Capital Management Incorporated, Toronto Dominion Capital

shares, 25,000 shares, 12,000 shares and 12,000 shares, respectively, of Series
C preferred stock on terms substantially similar to those set forth in the 1997
securities purchase agreement. These contributions were concurrently contributed
to Triton.


THE NORFOLK CONTRIBUTION

Pursuant to the terms of a Norfolk Preferred Stock Purchase agreement dated as
of December 31, 1998, Holdings received an additional contribution of $16.5
million from certain of the Cash Equity Investors in order to fund a portion of
the $111 million purchase price for the Norfolk Acquisition.  In consideration
therefor, at the closing of such acquisition, Holdings issued to such Cash
Equity Investors an additional $16.5 million of Holdings' Series C preferred
stock which it contributed to the Company.  At closing, Holdings also issued to
AT&T PCS an additional $14.6 million of Holdings' Series D preferred stock.  The
balance of the purchase price was financed through use of $96.6 million from the
net proceeds of the Private Offering.

THE AT&T AGREEMENTS

 The Stockholders' Agreement

  General.   Pursuant to a stockholders' agreement, dated as of February 4,
1998, by and among AT&T PCS, the Cash Equity Investors, the Management
Stockholders, David Clark, Clyde Smith, Patricia Gallagher, David Standig and
Michael Mears (collectively the "Other Management Stockholders") and 

                                       46
<PAGE>
 
Holdings, the stockholders and Holdings have agreed to certain matters in
connection with the management and operations of the Company and the sale,
transfer or other disposition of the capital stock of Holdings.

  Board of Directors.   Holdings is governed by a Board of Directors consisting
of seven persons, and, unless otherwise required, actions of the Board of
Directors require the affirmative vote of a majority of the entire Board of
Directors. The stockholders have agreed to vote for the seven persons as
follows: (i) two directors selected by a majority in interest of common stock
and securities convertible into common stock held by the Cash Equity Investors
in their sole discretion, (ii) two directors selected by a majority in interest
of common stock and securities convertible into common stock held by the Cash
Equity Investors, which directors shall be acceptable to Michael Kalogris and
Steven Skinner, on the one hand, and AT&T PCS, on the other hand, each in their
sole discretion, (iii) Michael Kalogris so long as he is an officer of Holdings,
(iv) Steven Skinner so long as he is an officer of Holdings, and (v) one
director selected by AT&T PCS in its capacity as holder of the Series A
preferred stock so long as it has the right to elect one director in accordance
with the Restated Certificate of Incorporation (as defined herein).
Representatives of AT&T PCS and certain Cash Equity Investors also have the
right to attend each meeting of the Board of Directors as observers, provided
that certain capital stock ownership thresholds are met. Any transactions
between the Company and the stockholders (other than the AT&T Agreements and
other arms-length agreements or transactions entered into from time to time
between the Company and AT&T) must be approved by a majority of disinterested
directors. Under the stockholders' agreement, the two directors selected
pursuant to clause (ii) above of this paragraph are deemed not to have been
designated by any of the stockholders. If an executive committee of the Board of
Directors is formed, it must consist of at least the Series A Director, one of
the directors selected pursuant to clause (i) above of this paragraph and
Michael Kalogris (so long as he is an officer of Holdings). The Cash Equity
Investors also have agreed to contribute all or part of the unfunded commitment
amount at any time to Holdings upon 20 business days' notice from the Board of
Directors.

  Restrictions on Transfer.   The stockholders' agreement imposes numerous
restrictions with respect to the sale, transfer or other disposition of the
capital stock of Holdings. Generally, prior to the date on which Holdings
receives in excess of $20 million in gross proceeds from the sale of common
stock pursuant to a registration statement under the Securities Act (the "IPO
Date"), no Transfers are permitted except: (i) Series C preferred stock, Series
D preferred stock and common stock may be transferred (at any time) (A) to an
affiliate of a person that is a transferee or a successor in interest to any or
all of such person's capital stock of Holdings and that is required to become a
party to the stockholders' agreement in accordance with the terms thereof (an
"Affiliated Successor") or (B) in the case of a transfer by a Cash Equity
Investor, to any partners, limited partners or members of a Cash Equity Investor
that are transferees of Series C preferred stock or common stock pursuant to
distributions in accordance with the partnership agreement or operating
agreement of such Cash Equity Investor (an "Equity Investor Affiliate"), (ii)
after the third anniversary of the securities purchase closing date, the Cash
Equity Investors may Transfer Series C preferred stock or common stock to
another Cash Equity Investor, and (iii) after the third anniversary of the
securities purchase closing date, Series C preferred stock and common stock may
be transferred to any person (except a prohibited transferee), subject to
certain rights of first refusal of the non-transferring stockholders (the
"Rights of First Refusal"). Additionally, prior to the IPO Date, (x) no Cash
Equity Investor nor AT&T PCS may Transfer less than all of its Series C
preferred stock or common stock to any person except an Affiliated Successor or
a Equity Investor Affiliate unless after giving effect to such Transfer, the
transferor and the transferee will each own at least the lesser of (A) 5% of
common stock and (B) one-half of the common stock beneficially owned by such
transferor on the date of Transfer, and (y) no Management Stockholder or Other
Management Stockholder (together, the "Employee Stockholders") may effect more
that one Transfer of its common stock during any 12-month period to any person
other than an Affiliated Successor.

  On and after the IPO Date, no Transfers of Series D preferred stock or common
stock are generally permitted except: (i) after the third anniversary of the
securities purchase closing date, the Cash Equity Investors may Transfer Series
C preferred stock or common stock to another Cash Equity Investor, (ii) Series D
preferred stock and common stock may be transferred (at any time) to an
Affiliated Successor or 

                                       47
<PAGE>
 
an Equity Investor Affiliate and (iii) common stock may be transferred to any
person, subject to certain rights of first refusal.

  AT&T PCS is subject to all of the foregoing restrictions with respect to its
Series C preferred stock and common stock. AT&T PCS may not Transfer any of its
Series D preferred stock at any time other than to an Affiliated Successor.
Finally, with respect to AT&T PCS' Series A preferred stock, (a) prior to the
IPO Date, no Transfers are permitted except (i) to an Affiliated Successor or
(ii) to any person after first complying with certain provisions relating to the
rights of first refusal, and (b) on or after IPO Date, no Transfer restrictions
exist.

  In addition to the foregoing transfer restrictions, each stockholder has
agreed, subject to certain exceptions, not to Transfer any Series A preferred
stock, Series B preferred stock, Series D preferred stock or common stock to a
Prohibited Transferee. A "Prohibited Transferee" is defined generally as one of
the three largest carriers (other than AT&T, or any person that derives a
material portion of its business from wireless communications systems and
utilizes TDMA technology in a substantial majority of those systems) of
telecommunications services that currently constitute interexchange services.

  Registration Rights.   The stockholders' agreement grants certain demand and
piggyback registration rights to the Stockholders. On or after the 91st day
after the IPO Date, the following Stockholders may cause an underwritten demand
registration, subject to customary pro rata cutback and blackout restrictions,
so long as such registration is reasonably expected to result in aggregate
proceeds of at least $10 million: (a) AT&T PCS, (b) a holder of shares of Series
C preferred stock or common stock (if such registration is reasonably expected
to result in aggregate gross proceeds of at least $25 million) or (c) Employee
Stockholders beneficially owning at least 50.1% of the shares of common stock
then beneficially owned by the Employee Stockholders. In addition to such demand
registration rights, any Stockholder may piggyback on a registration by Holdings
at any time (other than registrations on Forms S-4 or S-8 of the Securities
Act), subject to customary pro rata cutback restrictions. The demand and
piggyback registration rights and obligations survive 20 years.

  Furthermore, if the IPO Date has not occurred by the fifth anniversary of the
securities purchase closing date, Holdings, at the request of (i) any holders
beneficially owning in the aggregate greater than one-third of the Series C
preferred stock and common stock then outstanding or (ii) AT&T PCS for so long
as it beneficially owns greater than two-thirds of the initial issuance to AT&T
PCS of Series A preferred stock, shall undertake a registration of common stock
that results in the IPO Date.

  Preemptive Rights.   The stockholders' agreement grants preemptive rights in
certain circumstances to the Stockholders. If, on or prior to the IPO Date,
Holdings proposes to issue any equity security (including in an initial public
offering, but excluding pursuant to any stock option or stock appreciation
rights plan), for cash, each Stockholder shall have a preemptive right to
purchase its pro rata portion of such securities.

  Exclusivity.   Holdings and the stockholders have also reached several
agreements regarding operational matters pertaining to the Company. The
Stockholders have agreed that during the term of the Stockholders' Agreement,
none of the Stockholders nor their respective affiliates will provide or resell,
or act as the agent for any person offering, within the Territory (as defined in
the stockholders' agreement) mobile wireless telecommunications services
initiated or terminated using TDMA and frequencies licensed by the FCC ("Company
Communications Services"), except AT&T PCS and its affiliates may (i) resell or
act as agent for the Company in connection with the provision of Company
Communications Services, (ii) provide or resell wireless telecommunications
services to or from certain specific locations, and (iii) resell Company
Communications Services for another person in any area where the Company has not
yet placed a system into commercial service; provided that AT&T PCS has provided
the Company with prior written notice of AT&T PCS' intention to do so and only
dual band/dual mode phones are used in connection with such resale activities.
Additionally, with respect to the markets listed in the roaming agreement, each
of the Company and AT&T PCS agrees to cause their respective affiliates in their
home carrier capacities to (a) program and direct the programming of customer
equipment so that the other party in its capacity as the

                                       48
<PAGE>
 
serving carrier is the preferred provider in such markets, and (b) refrain from
inducing any of its customers to change such programming.

  Build-Out.   The Company is bound to certain operational obligations,
including meeting the construction requirements set forth in an agreed-upon
minimum build-out plan, ensuring compatibility of the Company's PCS systems with
the majority of systems in the southeastern region of the United States,
satisfying the FCC construction requirements in the Territory, offering certain
core service features with respect to its systems, causing the Company's systems
to comply with AT&T PCS' TDMA quality standards, and refraining from providing
or reselling interexchange services other than interexchange services that
constitute Company Communications Services or that are procured from AT&T. In
the event that the Company materially breaches any of the foregoing operational
obligations or if, in the event AT&T PCS decides to adopt in a majority of its
markets a new technology standard and the Company declines to adopt such new
technology, AT&T PCS may terminate its exclusivity obligations.

  Certain Transactions.   In the event a merger, consolidation, asset
acquisition or disposition or other business combination involving (i) AT&T and
(ii) a person that (a) derives from telecommunications businesses annual
revenues in excess of $5 billion, (b) derives less than one-third of its
aggregate revenues from the provision of wireless telecommunications and (c)
owns FCC licenses to offer (and does offer) mobile wireless telecommunications
services serving more than 25% of the Pops within the Territory (such person,
the "Other Party"), the Company and AT&T have certain rights, including the
following: (i) AT&T may, upon written notice, terminate certain of its
obligations described above under the caption "--Exclusivity" in the portion of
the Territory in which the Other Party owns an FCC license to offer CMRS;
provided, that, upon such termination, the Company has the right to cause AT&T
PCS to exchange (A) certain shares of its Series A preferred stock into Series B
preferred stock and (B) certain shares of its Series D preferred stock (or
Series C preferred stock or common stock into which such Series D preferred
stock has been converted) into Series B preferred stock; (ii) if AT&T PCS
proposes to sell, transfer or assign to any non-affiliate any PCS system owned
and operated by AT&T PCS and its affiliates in any of the Charlotte, NC,
Atlanta, GA, Baltimore/Washington, D.C. or Richmond, VA BTAs (the "Subject
Markets"), then AT&T PCS will provide the Company with the opportunity for a
180-day period to have AT&T PCS joint market with the applicable Subject Markets
the portion of the Territory included in the MTA that includes such Subject
Markets.

  Without the prior written consent of AT&T PCS, Holdings and its subsidiaries
may not effect any sale of substantially all of the assets of Holdings or any of
its subsidiaries or liquidation, merger or consolidation of Holdings or any of
its subsidiaries, with certain limited exceptions.

  Acquisition of Licenses.   The Company may acquire cellular licenses that the
Board of Directors has determined are demonstrably superior alternatives to
constructing a PCS system in the applicable area within the Territory, provided
that: (i) a majority of the cellular Pops are within the Territory, (ii) AT&T
PCS and its affiliates do not own Commercial Mobile Radio Service licenses in
such area, and (iii) the Company's ownership of such cellular license will not
cause AT&T PCS or any affiliate to be in breach of any law or contract.

  Equipment, Discounts and Roaming.   If requested by the Company, AT&T PCS has
agreed to use all commercially reasonable efforts (i) to assist the Company in
obtaining discounts from any vendor with whom the Company is negotiating for the
purchase of any infrastructure equipment or billing services and (ii) to enable
the Company to become a party to the roaming agreements between AT&T PCS and its
affiliates and operators of other cellular and PCS systems.

  Resale Agreements.   The Company, upon the request of AT&T PCS, will enter
into resale agreements relating to the Territory. The rates, terms and
conditions of service provided by the Company shall be at least as favorable to
AT&T PCS, taken as a whole, as the rates, terms and conditions provided by the
Company to other customers.

                                       49
<PAGE>
 
  Subsidiaries.   All of Holdings' subsidiaries must be direct or indirect
wholly-owned subsidiaries of Holdings.

  Amendments.   Amendments to the stockholders' agreement require the consent of
holders of (i) a majority of the shares of each class of capital stock,
including AT&T PCS, (ii) two-thirds of the common stock beneficially owned by
the Cash Equity Investors, and (iii) 60.1% of the common stock beneficially
owned by the Employee Stockholders; provided however, that in the event any
party thereto ceases to own any shares of Equity Securities, such party ceases
to be a party to the stockholders' agreement and the rights and obligations of
such party thereunder terminates.

  Termination.   The stockholders' agreement terminates upon the earliest to
occur of (i) the written consent of each party thereto, (ii) the eleventh
anniversary of the securities purchase closing date, and (iii) one Stockholder
owning all the Common Stock; provided, some provisions expire on the IPO Date
and certain consent rights of AT&T PCS expire when it fails to own the requisite
amount of capital stock of Holdings.

 License Agreement

  Pursuant to the Network Membership License Agreement, dated as of February 4,
1998, between AT&T Corp. and Operating LLC, AT&T Corp. has granted to the
Company a royalty-free, non-transferable, non-sublicensable, non-exclusive,
limited right and license to use the Licensed Marks solely in connection with
Licensed Activities. The Licensed Marks include the logo containing the AT&T and
globe design and the expression "Member, AT&T Wireless Services Network." The
"Licensed Activities" include (i) the provision to end-users and resellers,
solely within the Territory, of Company Communications Services on frequencies
licensed to the Company for Commercial Mobile Radio Service provided in
accordance with the AT&T Agreements (collectively, the "Licensed Services") and
(ii) marketing and offering the Licensed Services within the Territory. The
License Agreement also grants to the Company the right and license to use
Licensed Marks on certain permitted mobile phones.

  Except in certain instances, AT&T has agreed not to grant to any other person
a right or license to provide or resell, or act as agent for any person
offering, Company Communications Services within the Territory under the
Licensed Marks. In all other instances, AT&T reserves for itself the right to
use the Licensed Marks in the providing of its services (subject to its
exclusivity obligations described above), whether within or without the
Territory.

  The license agreement contains numerous restrictions with respect to the use
and modification of any of the Licensed Marks. Furthermore, the Company is
obligated to use commercially reasonable efforts to cause all Licensed Services
marketed and provided using the Licensed Marks to be of comparable quality to
the Licensed Services marketed and provided by AT&T in areas that are comparable
to the Territory taking into account, among other things, the relative stage of
development of the areas. The license agreement also sets forth specific testing
procedures to determine compliance with these standards, and affords the Company
with a grace period to cure any instances of alleged noncompliance therewith.
Following the cure period, the Company must cease using the Licensed Marks until
the Company is back in compliance.

  The Company may not assign or sublicense any of its rights under the license
agreement; provided, however, that the License Agreement may be, and has been,
assigned to the Company's lenders under our Credit Facility and after the
expiration of any applicable grace and cure periods under the Credit Facility,
such lenders may enforce the Company's rights under the license agreement and
assign the License Agreement to any person with AT&T's consent.

  The term of the license agreement is for five years (the "Initial Term") and
renews for an additional five-year period if neither party terminates the
Agreement. The license agreement may be terminated by AT&T at any time in the
event of a significant breach by the Company, including the Company's misuse 

                                       50
<PAGE>
 
of any Licensed Marks, the Company licensing or assigning any of the rights in
the license agreement, the Company's failure to maintain AT&T's quality
standards or a change in control of the Company occurs. After the Initial Term,
in the event AT&T converts any shares of Series A preferred stock into common
stock in connection with a transaction described above under the caption "--
Stockholders' Agreement--" the license agreement terminates on the later of (i)
two years from the date of such conversion and (ii) the then existing expiration
date of the license agreement. After the Initial Term, AT&T may also terminate
the license agreement upon the occurrence of certain transactions described
above under the caption "--Stockholders' Agreement--."

 Roaming Agreement

  Pursuant to the Intercarrier Roamer Service Agreement, dated as of February 4,
1998, between AT&T Wireless Service, Inc. (on behalf of its affiliates) and
Operating LLC (on behalf of the Company), each of AT&T and the Company agrees to
provide (each in its capacity as serving provider, the "Serving Provider")
mobile wireless radiotelephone service for registered customers of the other
party's (the "Home Carrier") customers while such customers are out of the Home
Carrier's geographic area and in the geographic area where the Serving Carrier
(itself or through affiliates) holds a license or permit to construct and
operate a mobile wireless radiotelephone system and station. Each Home Carrier
whose customers receive service from a Serving Carrier shall pay to such Serving
Carrier 100% of the Serving Carrier's charges for wireless service and 100% of
pass-through charges (i.e., toll or other charges). Each Service Carrier's
service charges per minute or partial minute for the use for the first 3 years
will be fixed at a declining rate, and thereafter will be equal to an adjusted
average home rate or such lower rate as the parties negotiate from time to time;
provided, however, that with respect to the Norfolk BTA, the service rate is
equal to the lesser of (a) $0.25 per minute and (b) the applicable home rate of
AT&T PCS, or such other rate as agreed to by the parties. Each Serving Carrier's
toll charges per minute of use for the first 3 years will be fixed at a
declining rate, and thereafter such other rates as the parties negotiate from
time to time.

  The roaming agreement has a term of 20 years, unless earlier terminated by a
party due to the other party's uncured breach of any term of the roaming
agreement, the other party's voluntary liquidation or dissolution or the FCC
revoking or denying renewal of the other party's license or permit to provide
CMRS.

  Neither party may assign or transfer the roaming agreement or any of its
rights thereunder except to an assignee of all or part of its license or permit
to provide Commercial Mobile Radio Service, provided that such assignee
expressly assumes all or the applicable part of the obligations of such party
under the Roaming Agreement.

 Resale Agreement

  Pursuant to the terms of the stockholders' agreement, the Company is required
to enter into a Resale Agreement, substantially in the form of Exhibit C to the
securities purchase agreement (together with the stockholders' agreement, the
license agreement and the roaming agreement, the "AT&T Agreements"), at the
request of AT&T. Pursuant to the resale agreement, AT&T PCS will be granted the
right to purchase and resell on a nonexclusive basis access to and usage of the
Company's services in the Territory. AT&T PCS will pay to the Company the
charges, including usage and roaming charges, associated with services requested
by AT&T PCS under the Resale Agreement. The Company will retain the continuing
right to market and sell its services to customers and potential customers.

  The resale agreement will have a term of ten years and will renew
automatically for successive one-year periods unless either party elects to
terminate the resale agreement. Following the eleventh anniversary of the Resale
Agreement, either party may terminate on 90 days prior written notice.
Furthermore, AT&T PCS may terminate the resale agreement at any time for any
reason on 180 days written notice.

                                       51
<PAGE>
 
  Pursuant to the stockholders' agreement, Holdings has agreed that the rates,
terms and conditions of service, taken as a whole, provided by the Company to
AT&T PCS pursuant to the resale agreement shall be at least as favorable as (or
if permitted by applicable law, superior to) the rates, terms and conditions of
service, taken as a whole, provided by the Company to any other customer.
Without limiting the foregoing, the rate plans offered by the Company pursuant
to the resale agreement will be designed to result in a discounted average
actual rate per minute paid by AT&T PCS for service below the weighted average
actual rate per minute billed by the Company to its customers generally for
access and air time.

  Neither party may assign or transfer the resale agreement or any of its rights
thereunder without the other party's prior written consent, which will not be
unreasonably withheld, except (a) to an affiliate of that party at the time of
execution of the Resale Agreement, (b) by the Company to any of its operating
subsidiaries, and (c) to the transferee of a party's stock or substantially all
of its assets, provided that all FCC and other necessary approvals have been
received.


OTHER RELATED PARTY TRANSACTIONS

  The Company is associated with Triton Cellular Partners L.P. by virtue of
certain management overlap and the sharing of leased facilities. As part of this
association, certain costs are incurred on behalf of Triton Cellular and
subsequently reimbursed to the Company. Such costs totaled $482,000 during 1998.
In addition, under agreement between the Company and Triton Cellular,
allocations for management services rendered are charged to Triton Cellular.
Such allocations totaled $469,000 during 1998. The outstanding balance at
December 31, 1998 was $951,000. The Company expects settlement of these
outstanding charges during 1999.

  Over the course of fiscal year 1997, Triton L.L.C., a predecessor of Triton
License Company, incurred certain costs on behalf of Triton Cellular. Such costs
totaled $148,100 and will be reimbursed by Triton Cellular in 1998.   In
addition, the Company purchased $22,800 of equipment from Horizon Cellular
Telephone Company, L.P. , an entity affiliated with the Company by virtue of
management overlap and the sharing of leased facilities.

  On February 3, 1998, the Company entered into the credit facility. Certain
affiliates of each of J.P. Morgan Investment Corporation, a holder of
approximately 17% of the issued and outstanding capital stock of the Company,
and CB Capital Investors, a holder of approximately 20% of the issued and
outstanding capital stock of the Company, serve as agent and lenders under the
credit facility. Each of the agent and lenders under the credit facility have
received and will continue to receive customary fees and expenses in connection
with the execution of the credit facility. To date, affiliates of J.P. Morgan
Investment Corporation and CB Capital Investors, have received approximately $98
and $106, respectively, in their capacity as agent and lender under such
facility.

  On February 4, 1998, Holdings entered into letter agreements with Messrs.
Clark, Standig and Mears, and Ms. Gallagher in connection with their employment.
Pursuant to such letter agreements they were issued shares of common stock which
vest at 20 percent per year over a five year period. Messrs. Clark, Standig, and
Mears received 7,053.77, 3,526.89, and 2,351.26, respectively, and Ms. Gallagher
received 3,526.89. See "Security Ownership."

  On March 7, 1997, each of Chase Venture Capital Associates, L.P., an affiliate
of Chase Capital Partners, and J.P., Morgan Investment Corporation provided
$550,000 in financing, and on July 3, 1997, each of Chase Venture Capital
Associates, L.P. and J.P. Morgan Investment Corporation provided an additional
$250,000 in financing, to Triton L.L.C. in the form of convertible promissory
notes in order to fund Triton L.L.C.'s start-up costs. The $1.6 million in notes
originally bore interest at 14% annually, payable at maturity. On January 15,
1998, Triton L.L.C. assigned the notes to the Company. Triton, in 

                                       52
<PAGE>
 
conjunction with Holdings and the noteholders, subsequently negotiated a revised
arrangement under which no interest would be paid on the notes and, in lieu of
repaying the promissory notes in cash, the amount owed under such notes would be
convertible into approximately $3.2 million worth of Holdings' Series C
preferred stock. The conversion of the Triton L.L.C. notes into 16,000 shares
each of Series C preferred stock occurred on February 4, 1998. The $1.6 million
preferred return to the investors has been accounted for as a financing cost
during the period the notes were outstanding. Accordingly, the Company has
accrued $1.2 million in financing costs on the notes as of December 31, 1997.
The remaining $0.4 million financing costs were recognized in the first quarter
of calendar 1998.

  On January 19, 1998, Operating LLC entered into the Master Services Agreement
with Wireless Facilities Inc. ("WFI") pursuant to which WFI will provide radio
frequency design and system optimization support services to the Company. The

stock, acted as initial purchasers in connection with the private offering and
received a placement fee of $6.3 million in connection therewith.

          THIS MASTER BUILD TO SUIT LEASE AGREEMENT (the "Agreement") is entered
into as of the ______ day of November, 1998, by and between Crown Communication
Inc., a Delaware corporation ("CROWN"), and Triton PCS Property Company L.L.C.,

                                   --------

          CROWN will own, lease or otherwise control real property on which
CROWN will have constructed a wireless communications facility, including an
antenna support structure for the attachment of communications equipment. TRITON
wishes to lease from CROWN certain portions of such real property and the
wireless communications facility for the operation of TRITON's communications
facility. Each location for which TRITON, pursuant to this Agreement, enters
into a lease for a portion of the property and the wireless communications
facility will be referred to individually as a "Site" and collectively as
"Sites".

          TRITON is an affiliate of a provider of wireless communications
services which operates networks of wireless communications facilities. CROWN
and TRITON are desirous of establishing terms and conditions that will apply to
the leasing of certain Sites by CROWN to TRITON in the areas described in
Exhibit "A" to this Agreement.

          NOW, THEREFORE, in consideration of the mutual covenants contained in
this Agreement and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, CROWN and TRITON agree as follows:


                          1.  MASTER LEASE AGREEMENT
                          --------------------------

This Agreement contains the basic terms and conditions upon which each Site
shall be leased by CROWN to TRITON. When the parties agree on the particular
terms for a Site, the parties will execute a completed Site Lease Acknowledgment
in the form attached hereto as Exhibit "B" ("SLA"). Each executed SLA is deemed
to be a part of this Agreement. The terms and conditions of the SLA will govern
and control if there is a conflict or inconsistency between the terms and
conditions of a SLA and this Agreement. The SLA shall become effective and
become part of this Agreement upon its execution by both CROWN and TRITON. The
parties agree that an SLA shall terminate and have no force and effect if,
despite the reasonable efforts of Crown and Triton, a building permit for the
applicable Site is not issued or the Site Acquisition Package is not delivered
within a reasonable timeframe after the timeframes contemplated by this
Agreement. The parties acknowledge and agree that, notwithstanding any other
language in this Agreement to the contrary, TRITON's use of a Site pursuant to
this Agreement does not constitute a conveyance of any interest in real estate
to TRITON. The

5
<PAGE>
 
relationship between CROWN and TRITON is not one of tenancy and no leasehold
interest or other interest in real estate has been or will be created.

                  2.  SITE APPROVAL AND CONSTRUCTION PROCESS
                  ------------------------------------------

                            2.1 TRITON'S PROPOSALS
                            ----------------------

TRITON shall make CROWN aware of an opportunity to construct a group of Sites in
the areas identified in Exhibit "A" pursuant to this Agreement by providing
CROWN with a written proposal ("Proposal"), identifying the applicable search
areas for the potential Sites. TRITON and CROWN shall agree within twenty-one
(21) days of the execution of this Agreement upon the schedule to be set forth
on Exhibit "F".

As more fully described herein, CROWN will provide "Site Acquisition Services"
and "Construction Services" for the "A Sites" identified on Exhibit "A" (the "A
Sites") and "Construction Services" for the "B Sites" identified on Exhibit "A"
(the "B Sites"). CROWN will also be providing site development services to
TRITON for approximately 45 Sites pursuant to a Site Development Agreement
executed by the parties on November ____, 1998 (the "SDA"). The parties
expressly agree that if, at anytime during the term of this Agreement, CROWN
notifies TRITON of CROWN's preference to co-locate TRITON on an existing
structure in any of the areas described in Exhibit "A", rather than building a
Site pursuant to the terms of this Agreement, then TRITON agrees to co-locate on
such Sites if such Sites meet the requirements of Viable Co-Locate Candidates as
described in Exhibit "C-3, paragraph 5". In the event that the parties mutually
agree, as described in the preceding sentence, then their respective rights and
obligations with respect to such Sites, shall be governed by the SDA and they
shall have no further obligations hereunder with respect to such Sites.

                     2.2 COMMENCEMENT OF WORK; SLA PACKAGE
                     -------------------------------------

                                2.2.1  A SITES:
                                ---------------
                                        
Upon release of Search Areas CROWN will perform the Site Acquisition Services
set forth in Section 2.4. Thirty (30) days prior to the anticipated building
permit issue date CROWN will deliver a completed SLA to TRITON. Within ten (10)
days of receipt, TRITON will provide a response ( an "SLA Response") consisting
of: (i) return an executed SLA or; (ii) reject the SLA for reasons noted on the
SLA transmittal or; (iii) request an extension of review time as noted on the
SLA transmittal. TRITON shall provide for CROWN's engineering services, after
designation of a Primary Site, an RF site build specification (antenna and cable
size, type, and location information).

                                2.2.2  B SITES:
                                ---------------

6
<PAGE>
 
Upon TRITON's delivery or anticipated delivery of a Site Acquisition Package to
CROWN, no later than thirty (30) days prior to the anticipated building permit
issue date, CROWN will deliver a completed SLA to TRITON. Within ten (10) days
of receipt, TRITON will provide an SLA Response. The "Site Acquisition Package"
shall contain: (i) a ground lease and/or other instruments such as an easement
evidencing CROWN's real estate interest in the Site; (ii) a title abstract;
(iii) a Federal Aviation Administration ("FAA") approval; and (iv) a final non-
appealable zoning permit.

TRITON shall provide for CROWN's engineering services, after designation of a
Primary Site, an engineering information package (a "Tech Team Visit Checklist")
that includes: a site survey report, a sketch of the BTS, antenna and cable
locations, existing drawings and surveys (to the extent reasonably possible), a
deed, tax map, zoning map, zoning ordinance, applicable zoning application and
drawing preparation checklists (where they exist), RF site build specifications
(antenna and cable size, type, and location information) and site directions.

                             2.2.3  A AND B SITES

Upon designation of a "Primary Site", a Viable Candidate selected by TRITON,
CROWN will proceed with all required engineering services including but not
limited to surveys, drawings, geotechnical evaluations and environmental studies
unless otherwise directed by TRITON.

Failure of TRITON to provide CROWN with an SLA Response within ten (10) days
shall be deemed termination by TRITON pursuant to Section 2.4.2.

TRITON recognizes that the successful completion of CROWN's scope of work in
accordance with the schedules set forth in Exhibit "F", for B sites, depends on
the successful completion of Site Acquisition Services provided by independent
contractors engaged by TRITON who are not affiliated with CROWN. TRITON will
cause such contractors to cooperate with CROWN in the sharing information
required for the procurement of building permits included in CROWN's scope of
work.

                      2.3 SUBSTANTIAL COMPLETION OF SITE
                      ----------------------------------

Upon anticipated or actual receipt of the executed SLA, CROWN shall proceed to
perform the Services required by this Agreement by the dates identified in
Exhibit "F".
 
For the purposes of this Agreement, "Substantial Completion" of a Site and
Improvements is defined as the Site being constructed to TRITON standards (as
set forth in Exhibit "I") and the site being capable of transmitting and
receiving RF signal at it's designed and licensed frequency range without
violating equipment warrantees or any statute, law, or ordinance of any federal,
state, or local agency having jurisdiction. Substantial Completion is evidenced
by receipt and approval by TRITON of a Site Acceptance Package in a form
acceptable to TRITON. Unless otherwise specified in the applicable SLA,
Substantial Completion of a Site and Improvements specifically excludes
installation of TRITON's BTS (which will be performed by independent

7
<PAGE>
 
contractors), the provision of telephone service to TRITON's equipment, but
includes any CROWN service extension required to provide telephone service to
the Site and the utility work set forth in Section 2.4.3.3. The Substantial
Completion date may be extended by reason of an event of "Force Majeure" which
is defined as being any of the following events: delays in delivery of TRITON
provided construction materials, strikes, walk-outs, labor disputes, embargoes,
flood, earthquake, storm, dust storm, lightening, fire and any other weather
conditions that prevent construction (according to the tower construction
industry's standard of prudence), epidemic, acts of God, war, national
emergency, civil disturbance or disobedience, riot, sabotage, terrorism, threats
of sabotage or terrorism, restraint by court order or order of public authority,
and similar occurrences beyond the reasonable control of CROWN, and such non-
performance shall be excused for the period of time any such Force Majeure
causes such non-performance. The Substantial Completion period may also be
extended by mutual agreement of the parties.

            2.4 SITE ACQUISITION SERVICES AND CONSTRUCTION SERVICES
            -------------------------------------------------------

Services to be provided by CROWN shall include the Site Acquisition Services and
Construction Services described below:

                        2.4.1 SITE ACQUISITION SERVICES
                        -------------------------------

For the A Sites, CROWN will perform the "Site Acquisition Services" more fully
described in Exhibits "C-1", "C-2", "C-3", "C-4", "C-8" and "C-9".

The parties acknowledge that TRITON intends to engage independent third party
contractors not affiliated with CROWN to perform Site Acquisition Services for
the B Sites. TRITON agrees to cause such independent third party contractor to
meet both TRITON's site acquisition standards and the "Crown Site Acquisition
Standards" identified in Exhibit "E", to the extent possible, without delaying
the schedule set forth in Exhibit "F". TRITON further agrees to permit CROWN's
active participation in the candidate review process related to the B Sites
Furthermore, CROWN will reimburse TRITON for the actual site acquisition service
costs incurred for engaging such independent third party contractors up to a
maximum of $30,000 per B Site for which a building permit has been issued.

The parties acknowledge that from time to time during the zoning or building
permitting process, CROWN may want to reasonably continue with a proceeding that
TRITON either is not required to or is not desirous of continuing. In such
event, the parties agree that CROWN may continue to do so at its sole cost, so
long as such continuation by CROWN is not likely to delay the time frame set
forth on Exhibit "F", as determined within TRITON's reasonable discretion.

The parties also acknowledge that CROWN may desire to obtain zoning approval at
greater heights than required by TRITON to accommodate other tenants on the
tower. However, in no event shall CROWN attempt to obtain initial zoning
approval for a tower at such greater height if doing so in any way causes delay
in the approval of any permits required for TRITON's Improvements.

                          2.4.2 TERMINATION BY TRITON
                          ---------------------------

Notwithstanding any provision to the contrary, TRITON has the right of
termination of any Site or SLA at any time prior to the issuance of a building
permit for such Site by providing written notice of the same to CROWN. If CROWN
has not completed Services in accordance with the schedule set forth in Exhibit
"F" or the maximum average cycle times identified in Exhibit "F-2", and such
failure was not caused by TRITON or TRITON's contractor, CROWN will not be
compensated for the work performed prior to such Site termination and TRITON
shall have no further obligation hereunder with respect to such Site. In the
event of any termination without cause, TRITON shall pay to CROWN a termination
fee according to the schedule set forth in Exhibit "G" and shall have no further
obligations hereunder with respect to such Site. TRITON expressly agrees that it
shall have no right to terminate this Agreement with respect to a Site at any
time after CROWN commences construction on such Site, unless CROWN materially
breaches under this Agreement. TRITON may terminate this Agreement and any or
all SLAs executed in connection herewith upon executing an agreement with CROWN
to sell CROWN any communications tower owned by TRITON. Such termination upon
sale shall not apply to Sites for which a construction permit has been granted
and which is currently under construction.

                              ------------------------- 

TRITON may make changes at any time to the general scope of the Services
contained herein only by means of a written order (a "Change Order") issued by
CROWN and approved by TRITON. Any Change Order that exceeds the scope of
Services and which requires additional services on the part of CROWN shall
result in an adjustment of the price to be paid to CROWN. CROWN shall, upon
receipt of a written request for a Change Order from TRITON, provide TRITON with
an estimate of additional charges required to complete the proposed Change
Order. Prior to commencement of additional work, the proposed Change Order shall
be approved in writing by a TRITON representative. Any charges for additional
work commenced by CROWN without a written Change Order approved by a TRITON
representative may be denied by TRITON, in full or in part, in its sole
discretion.

                                2.5.3  SCHEDULE
                                ---------------

Within 21 days after execution of this Agreement, TRITON and CROWN shall agree
upon the schedule for the completion of Services on a site-by-site basis which
will replace Exhibit "F" to this Agreement. The schedule will contain milestone
dates for completion by CROWN of the following milestones: Site Selection, Site
Leasing and Site Zoning for A Sites, and Building Permit, Construction Start and
Construction Complete (Substantial Completion) for A and B sites. This Agreement
shall terminate upon notice by either party to the other if the parties are

TRITON has the right at any time upon written notice to require the removal of
any employee of CROWN or subcontractor utilized or supervised by CROWN in
TRITON's sole discretion. Resumes will be provided for review and approval prior
to CROWN's employees starting work on this project. CROWN will not add or remove
any personnel once assigned to the project and accepted by TRITON without prior
written agreement with TRITON. CROWN will use the necessary quantity and quality

                       --------------------------------

At the time each SLA is executed, the Site described in the SLA will be
undeveloped real estate. In accordance with Sections 2.3, 2.4 and 2.5 above,
CROWN will provide the Site Acquisition Services and the Construction Services
to TRITON. To enable TRITON to use the Site as a communications facility, CROWN
further agrees to substantially complete construction on each Site the
improvements described in Exhibit "D" (the "Improvements") on or before the
Substantial Completion date specified in Exhibit "F" for that Site. The timely
Substantial Completion of the Improvements is of the essence in this Agreement
and the SLA and, by execution of the SLA, CROWN confirms that the Substantial
Completion date is a reasonable period for the completion of the Improvements.
Construction of the Improvements will be completed (a) in a good and workmanlike
manner; (b) in accordance with all applicable governmental laws, codes, rules
and regulations; and (c) in accordance with the building plans. CROWN agrees
that it will be responsible for obtaining and maintaining any permits, zoning
approvals, variances or similar governmental requirements or approvals necessary
for the construction and operation of a wireless communications facility at the
Site, excluding, however, any FCC or other licenses related specifically to
TRITON's operations ("Government Approvals"). TRITON shall cooperate with CROWN
in obtaining Government Approvals, including acting as applicant, if necessary,
and executing documents reasonably needed to obtain the Government Approvals.
The parties agree that CROWN shall not be responsible for installing TRITON's

of the SLA. TRITON must, at TRITON's sole expense, comply with all laws, orders,
ordinances, regulations and directives of applicable federal, state, county and
municipal authorities or regulatory agencies including, without limitation, the
Federal Communications Commission (the "FCC"). TRITON shall operate and maintain
its equipment within its licensed frequency and power such that it does not
interfere with the operations at the communications facility or any other prior
existing users of the communications facility. CROWN agrees to cooperate with
TRITON, at TRITON's expense, in executing such documents or applications
required in order for TRITON to obtain such licenses, permits or other
Governmental Approvals needed for TRITON's permitted use of the Site.

                                ---------------

Each Site leased by CROWN to TRITON pursuant to a SLA shall be leased for an
initial term of twelve (12) years with the commencement date as of the date of
full execution of the particular SLA ("Commencement Date"). The term of each
particular SLA shall automatically be extended for up to three (3) additional
five (5) year terms unless TRITON terminates it at the end of the then current
term by giving CROWN written notice of the intent to terminate at least six (6)
months prior to the end of the then current term. Notwithstanding the foregoing,
if CROWN's rights in the Site are derived from a prime lease or other agreement
with a third party ("Prime Lease") and such Prime Lease has a shorter term or
extension terms than those provided for under this paragraph, then TRITON's
right to extend any particular SLA shall only be for as long as CROWN retains
its interest in the same applicable property pursuant to said Prime Lease.

                         6.  SITE APPROVAL TERMINATION
                         -----------------------------

In the event any previously approved zoning or governmental permit affecting the
use of the property or the Site as a communications facility is withdrawn or
terminated, the SLA relating to the property covered by said permit or approval
shall be deemed to have been terminated effective the date of the termination of
the permit or approval. In addition to any other rights to terminate an SLA,
CROWN has a right to terminate an SLA, and TRITON's rights related to

13

                                   --------

                            8.1 NO LIENS BY TRITON
                            ----------------------

TRITON must keep the Site free from any liens arising from any work performed or
materials furnished by or at the request of TRITON. If any such lien is filed
against the Site as a result of the acts or omissions of TRITON's employees,
agents or contractors, TRITON must discharge the lien or bond the lien off in a
manner reasonably satisfactory to CROWN within thirty (30) days after TRITON
receives written notice from any party that the lien has been filed. If TRITON
fails to discharge or bond any such lien within such period, then, in addition
to any other right or remedy of CROWN, CROWN may, at CROWN's election, discharge
the lien by either paying the amount claimed to be due or obtaining the
discharge by deposit with a court or a title company or by bonding. TRITON must
pay on demand any amount paid by CROWN for the discharge or satisfaction of any
lien, and all reasonable attorneys' fees and other legal expenses of CROWN
incurred in defending any such action or in obtaining the discharge of such
lien, together with all necessary disbursements in connection therewith.

                          --------------------------

CROWN hereby waives any and all lien rights it may have, statutory or otherwise,
concerning TRITON's equipment or any portion thereof, which shall be deemed
personal property for the purposes of this Agreement, regardless of whether or
not same is deemed real or personal property under applicable laws, and CROWN
gives TRITON the right to remove all or any portion of same from time to time in
TRITON's sole discretion and without CROWN'S consent.

<PAGE>
 
CROWN represents and warrants with respect to each Site that, upon Substantial
Completion of the Site and the Improvements for a period of one year thereafter,
such Site and Improvements will be in good operating condition, suitable for
their intended purpose. The foregoing representation and warranty shall not
extend to any materials or equipment provided by TRITON or for services properly
performed by CROWN within the stricter of CROWN, TRITON, and Ericsson standards
described herein or any applicable codes, statutes ordinances, regulations or
other requirements of any government unit or authority having jurisdiction.

                             10.  SITE ALTERATIONS
                             ---------------------

                              10.1 APPROVED SITE
                              ------------------

TRITON has the right to erect, maintain, replace and operate at the Site only
that communications equipment specified on the SLA. It is understood that TRITON
shall have the right at each and every Site, subject to compliance with the
terms of this Agreement and particularly those set forth in this Section, to
replace the equipment described in a SLA with similar and comparable equipment
so long as: (a) there is no greater wind loading, structural loading, size,
weight or height; and (b) the equipment operates at the frequency or range of
frequencies designated in the applicable SLA, or at the frequency or range of
frequencies identified in TRITON's current FCC licensee or successor licensee
thereto, for the transmission of wireless communications signals at that given
Site. It is understood that any such replacement equipment must be frequency
compatible with then existing uses of the Site. Prior to commencing any material
alteration at a Site and prior to accessing the communications tower structure
for any reason whatsoever, TRITON must obtain CROWN's approval of:

          (a)  TRITON's plans for material alteration work; and

          (b)  the contractor performing the material alteration or in any way
               accessing the tower structure itself.

CROWN's approval must not be unreasonably withheld, conditioned or delayed. All
of TRITON's alteration work must be performed:

          (a)  at TRITON's sole cost and expense;

          (b)  in a good and workmanlike manner, using the care and skill
               ordinarily used by members of the profession practicing under
               similar conditions at the same time and in the same geographic
               area;

          (c)  in accordance with applicable building codes and with the
               provisions of Exhibit "I"; and

16
<PAGE>
 
          (d)  must not adversely affect the structural integrity or maintenance
               of the Site or any structure on or use of the Site.

Any alterations to a structure at the Site must be designed, at TRITON's sole
cost and expense, by a structural engineer licensed in the jurisdiction where
the Site is located. Notwithstanding the foregoing, for any structural
alterations of the communications facility, such structural engineer must be
approved by CROWN which approval will not be unreasonably withheld, conditioned
or delayed. For structural alterations requiring a municipal permit, the
structural engineer must be satisfactory to the local municipality.

Following the initial installation at a Site, any installation, maintenance,
material alteration or removal of equipment at a Site by TRITON and any
activities whatsoever requiring access to a tower structure, must be performed
by a contractor reasonably acceptable to CROWN (which acceptance may
specifically include a requirement that all such contractors provide to CROWN,
in advance of any such work, certificates of insurance consistent with the
provisions of this Agreement). CROWN's consent thereto shall not be unreasonably
withheld, conditioned or delayed.

Said erection, maintenance, replacement and operation will in no way damage or
mechanically interfere with CROWN's use of or any operations at the
communications facility. If damage or mechanical interference is caused by
TRITON and TRITON fails to make such repairs immediately after notice by CROWN,
CROWN may make the repairs and the reasonable costs thereof shall be payable to
CROWN by TRITON upon written notice. If TRITON does not make payment to CROWN
within thirty (30) days after such notice, CROWN shall have the right to
immediately terminate the applicable SLA. No materials may be used in the
installation of the antennas or transmission lines that will cause corrosion or
rust or deterioration of the tower structure or its appurtenances.

                                11.  UTILITIES
                                --------------

TRITON acknowledges that CROWN's obligation as to utility service is indicated
above in Section 2.4.3.3. TRITON has the right, at TRITON's sole cost and
expense, to obtain electrical and telephone service to TRITON's equipment at the
Site subject to the terms and conditions of this Agreement and any limitations
contained in underlying real estate interests, including the Prime Lease. TRITON
understands and acknowledges that:

          (a)  the Site includes such non-exclusive easements as necessary to
               enable TRITON to connect utility wires, cables, fibers and
               conduits to its equipment; and

          (b)  CROWN does have the right to approve the route and the manner of
               installation which approval shall not be unreasonably withheld,
               conditioned or delayed.

                                  -----------

TRITON shall have free access during the term of a SLA to the Site twenty-four
(24) hours per day, seven (7) days per week. TRITON acknowledges that the
foregoing access rights are subject to any restrictions identified in the
underlying real estate interests related to the communications facility,
including but not limited to any restrictions identified in the Prime Lease.
CROWN shall furnish TRITON with necessary devices for the purpose of ingress and
egress to the said Site and communications facility. It is agreed, however, that
only authorized engineers, employees or properly authorized contractors of
TRITON or persons under their direct supervision will be permitted to enter said
Site. TRITON will retain ownership of all buildings, equipment and appurtenances
TRITON installs at any Site; provided, however, that the removal of said
equipment will not adversely affect the integrity of any structures.

                           13.  MEMORANDUM OF LEASE
                           ------------------------

After execution of a SLA, each party, at the request of the other, will sign a
recordable Memorandum of Lease for the Site described in the SLA. CROWN, at its
sole expense, shall record the Memorandum of Lease in the land records of the
recording office(s) responsible for notice purposes.

CROWN covering the Site, any overall improvements thereon, or the Site; or (b)
will increase the existing premiums for any such policy beyond that contemplated
for the addition of TRITON's communications equipment.

                           ------------------------

TRITON and CROWN agree to review the insurance requirements set forth in sub-

                             ---------------------

All insurers will be rated A-IX(9) or better and must be licensed to do business
in the jurisdiction where the respective Sites are located. The provision of
insurance required in this Agreement shall not be construed to limit or

its subcontractors', servants', agents' or invitees' use or occupancy of the
Site, including but not limited to any claim of liability or loss associated
with any Environmental Hazards as defined in this Agreement, excepting, however,
such claims or damages as may be due to or caused by the negligence or willful
misconduct of CROWN, or its subcontractors, servants, agents or invitees. If
CROWN is made a party to any litigation commenced by or against TRITON for any
of the above reasons, then TRITON shall protect and hold CROWN harmless and pay
all costs, penalties, charges, damages, expenses and reasonable attorneys' fees
incurred or paid by CROWN in connection therewith.

                           16.1 ASSIGNMENT BY TRITON
                           -------------------------

This Agreement may not be sold, assigned or transferred, in whole or in part, by
TRITON without prior approval or consent of CROWN (such approval and consent not
to be unreasonably withheld, conditioned, or delayed); provided, however, that,
notwithstanding anything to the

20
<PAGE>
 
contrary contained herein, TRITON may sell, assign or transfer this Agreement or
any SLA without the written approval or consent of CROWN to (i) any affiliate of
TRITON or (ii) any person or entity that acquires, through merger, purchase or
otherwise, all or substantially all of the assets of TRITON. Additionally,
TRITON may, upon notice to CROWN, mortgage or grant a security interest in this
Agreement and TRITON's equipment, and may assign this Agreement and such
equipment to any such mortgagees or holders of security interests including
their successors or assigns (hereinafter collectively referred to as
"Mortgagees"). In such event, CROWN shall execute such consent to leasehold
financing as may reasonably be required by Mortgagees.

                           16.2 ASSIGNMENT BY CROWN
                           ------------------------

This Agreement may not be sold, assigned or transferred, in whole or in part, by
CROWN without prior approval or consent of TRITON, which consent may not be
unreasonably witheld, conditioned or delayed. Furthermore, CROWN may assign its
interest herein without TRITON's approval once all sites under this agreement
are accepted by TRITON. Without limiting the foregoing, TRITON acknowledges that
CROWN intends to assign its rights and obligations with respect as to Site
Acquisition Services, Construction Services and any services related to the
Improvements to its wholly-owned subsidiary Crown Network Systems, Inc., a
Pennsylvania corporation. Additionally, CROWN may, upon notice to TRITON,
mortgage or grant a security interest in this Agreement or any of its assets
related to this Agreement, and may assign this Agreement and such assets to any
such mortgagees or holders of security interests including their successors and
assigns (hereinafter collectively referred to as "Mortgagees"). In such event,
TRITON shall execute such consent to leasehold financing as may reasonably be
required by Mortgagees.

                         17.  CASUALTY OR CONDEMNATION
                         -----------------------------

                                 17.1 CASUALTY
                                 -------------

If there is a casualty to any structure upon which a TRITON communications
facility is located, CROWN must within forty-five (45) days repair or restore
the structure. During said period of repair or restoration, fees identified in
this Agreement applicable to that Site shall be abated. Upon completion of such
repair or restoration, TRITON is entitled to reinstall TRITON's communications
equipment. In the event such repairs or restoration will reasonably require more
than forty-five (45) days to complete, TRITON is entitled to terminate the
applicable SLA upon thirty (30) days prior written notice. Notwithstanding the
foregoing, TRITON may elect to pursue on its own, or through CROWN, an alternate
Site if such Site can be constructed in a shorter timeframe as reasonably
determined by TRITON.

                               17.2 CONDEMNATION
                               -----------------

If there is a condemnation of the Site, including without limitation a transfer
of the Site by consensual deed in lieu of condemnation, then the SLA for the
condemned Site will terminate upon transfer of title to the condemning
authority, without further liability to either party under this Agreement.
TRITON is entitled to pursue a separate condemnation award for TRITON's
communications equipment from the condemning authority.

                            18.  SURRENDER OF SITE
                            ----------------------

TRITON, upon termination of the Agreement or the applicable SLA, shall have
removed its equipment, personal property and all fixtures and have restored the
Site to its original condition, reasonable wear and tear excepted. If such time
for removal causes TRITON to remain on the Site after termination of this
Agreement or the applicable SLA, the annual fee shall be increased to one and
one-half times the then existing annual fee until such time as the removal of
all equipment is completed. Nothing in this provision shall be construed as
providing TRITON the right to hold over and CROWN, immediately upon the
termination or expiration of the Agreement or the applicable SLA, shall have the
right to remove TRITON from the Site.

                               19.  INTERFERENCE
                               -----------------

TRITON agrees to have installed transmitting and receiving equipment of the
type, power and frequency consistent with its licenses. In the event TRITON'S
equipment fails to operate within such licensed power or frequency, and causes
interference, TRITON will take steps customary and reasonably necessary within
48 hours to eliminate such interference in a timely manner. CROWN agrees that
any future users of the Site who take possession after the date of execution of
any SLA will have properly installed transmitting and receiving equipment of the
type and frequency which will not cause interference to TRITON as defined by the
FCC. This provision shall not apply to test periods where the source of the
interference is being determined for purposes of suppression. IN THE EVENT THAT
ANY DEVICES INSTALLED ON A SITE AFTER THE DATE OF TRITON'S INSTALLATION AT SUCH
SITE, BY ANY AUTHORIZED USER SHALL INTERFERE WITH TRITON'S TRANSMISSION OR
RECEPTION, CROWN SHALL CAUSE THE INTERFERENCE TO BE ELIMINATED AS SOON AS
REASONABLY POSSIBLE AT NO COST TO TRITON. In the event such interference to
TRITON caused by a future user on a site is not analyzed with corrections
initiated within 48 hours, and does not cease within a reasonable period, the
parties acknowledge that continuing interference will cause irreparable injury
to TRITON and TRITON shall have the right, in addition to any other rights that
it may have at law or equity, to bring action to enjoin the interference or to
terminate the applicable SLA.

                             ---------------------

The occurrence of any one or more of the following events constitutes an "Event
of Default" by TRITON under this Agreement:

          (a)  if TRITON fails with respect to any Site to pay any fee or other
               sums payable by TRITON within thirty (30) business days of
               TRITON's receipt of written request for payment;

          (b)  breach of any agreement, representation, warranty or covenant set
               forth in this Agreement including any SLA, with the exception of
               the non-payment of any fee or other sums by TRITON, which is not
               cured within thirty (30) days of receipt of written notice,
               except such thirty (30) day cure period will be extended as
               reasonably necessary to permit TRITON to complete the cure so
               long as TRITON commences the cure within such thirty (30) day
               period and thereafter continuously and diligently pursues and
               completes such cure;

          (c)  if any petition is filed by or against TRITON, under any section
               or chapter of the present or any future federal Bankruptcy Code
               or under any similar law or statute of the United States or any
               state thereof (and with respect to any petition filed against
               TRITON, such petition is not dismissed within sixty (60) days
               after the filing thereof), or TRITON is adjudged bankrupt or
               insolvent in proceedings filed under any section or chapter of
               the present or any future Bankruptcy Code or under any similar
               law or statute of the United States or any state thereof;

          (d)  if a receiver, custodian or trustee is appointed for TRITON or
               for any of the assets of TRITON and such appointment is not
               vacated within sixty (60) days of the date of appointment; or

          (e)  if TRITON makes a transfer in fraud of creditors.

                             20.2 CROWN'S REMEDIES
                             ---------------------

If an Event of Default occurs, CROWN (without notice or demand except as
expressly required above) may terminate this Agreement including applicable
SLAs, in which event TRITON will immediately surrender the Sites to CROWN.
TRITON will become liable for damages equal to the total of:

23
<PAGE>
 
          (a)  the amounts owed hereunder; and

          (b)  the amount of any fees and other benefits that CROWN would have
               received under the applicable SLAs for the remainder of the term
               under the applicable SLA.

CROWN may elect any one or more of the foregoing remedies with respect to this
Agreement or to any particular SLA. CROWN agrees to forego seeking any
consequential damages.

                  20.3 CROWN'S DEFAULT AND TRITON'S REMEDIES
                  ------------------------------------------

If CROWN is in breach of any representation, warranty or covenant set forth in
this Agreement or any Exhibit hereto and such breach is not cured within thirty
(30) days of receipt of written notice thereof, except such thirty (30) day cure
period will be extended as reasonably necessary to permit CROWN to complete the
cure so long as CROWN commences the cure within such thirty (30) day period and
thereafter continuously and diligently pursues and completes such cure, TRITON
may, at TRITON's option and upon written notice:

          (a)  terminate the applicable SLA; or

          (b)  incur any expense reasonably necessary to perform the obligation
               of CROWN specified in such notice and invoice CROWN for the
               actual expenses, together with interest as set forth herein from
               the date named. (Any invoice shall be accompanied by
               documentation reasonably detailing actual expenses. If CROWN
               fails to reimburse the costs within thirty (30) days of receipt
               of written notice, then TRITON is entitled to offset and deduct
               such expenses from the fees or other charges next becoming due
               under any SLA.)

TRITON agrees to forego seeking any consequential damages.

and performance of all the material terms, covenants and conditions under this
Agreement, will have, hold and enjoy each Site leased under a SLA during the

take any action not expressly permitted under the terms of this Agreement that
will interfere with TRITON's intended use of the Site nor will CROWN fail to
take any action or perform any obligation identified in this Agreement to
fulfill CROWN's aforesaid covenant of quiet enjoyment in favor of TRITON.

                          --------------------------

CROWN represents and warrants that to the best of CROWN's knowledge there are no
Environmental Hazards on any Site. Nothing in this Agreement or in any SLA will
be construed or interpreted to require that TRITON remediate any Environmental
Hazards located at any Site unless TRITON or TRITON's officers, employee, agents
or contractors placed the Environmental Hazards on the Site. TRITON will not
bring to, transport across or dispose of any Environmental Hazards on any
particular premises or Site without CROWN's prior written approval, which
approval shall not unduly be withheld or delayed. TRITON's use of any approved
substances constituting Environmental Hazards must comply with all applicable
laws, ordinances and regulations governing such use.

The term "Environmental Hazards" means hazardous substances, hazardous wastes,
pollutants, asbestos, polychlorinated biphenyl (PCB), petroleum or other fuels
(including crude oil or any fraction or derivative thereof) and underground
storage tanks. The term "Hazardous Substances" shall be defined in the
Comprehensive Environmental Response, Compensation, and Liability Act, and any
regulations promulgated pursuant thereto. The term "Pollutants" shall be as
defined in the Clean Water Act, and any regulations promulgated pursuant

                               ----------------

The parties acknowledge that CROWN's rights in a Site may be derived from a
separate agreement with a third party hereinafter referred to generally as a
"Prime Lease," in which CROWN is lessee, grantee or licensee therein. If this is
the case, a copy of said Prime Lease shall be attached as Exhibit "4" to the
SLA, and the following provisions shall be applicable. In the event approval of
the prime lessor, grantor or licensor is required in the Prime Lease, the
effectiveness of any SLA concerning such property shall be specifically subject
to the obtaining of such approval. Further, all the terms, conditions and
covenants contained in this Agreement shall be specifically subject to and
subordinate to the terms and conditions of any Prime Lease affecting the Site
that is the subject of the particular SLA. In the event any of the provisions of
the Prime Lease supersede or contradict the terms of this Agreement, such terms
of this Agreement shall be deemed deleted or superseded to the extent of the
contradiction as applicable to the Site utilized by TRITON. Further, TRITON
agrees to be bound by and agrees to perform all the acts and responsibilities
required of the lessee, grantee or licensee pursuant to the Prime Lease as are
applicable to the access and occupancy of the premises utilized by TRITON.
Lastly, in the event the Prime Lease terminates for any reason, the SLA relating
to the Site covered by said Prime Lease, shall be deemed to have terminated
effective the date of the termination of the Prime Lease.

                             25.  ENTIRE AGREEMENT
                             ---------------------
It is agreed and understood that this Agreement, including all SLAs, contain all
the agreements, promises and understandings between CROWN and TRITON as to the
Build to Suit services set forth herein and that no verbal or oral agreements,
promises or understandings shall be binding upon either CROWN or TRITON in any
dispute, controversy or proceeding at law, and any addition, variation or
modification to this Agreement shall be void and ineffective unless made in
writing signed by the parties. As such, this Agreement revokes and supersedes
any other oral or written agreements between the parties, whether or not in
writing, that pertain to the subject matter described herein. Notwithstanding
the foregoing, the parties agree to continue to be bound by that Confidentiality
Agreement dated November 12, 1998.

                               26.  SEVERABILITY
                               -----------------

If any provision of this Agreement or any SLA is invalid or unenforceable with
respect to any party, the remainder of this Agreement, or the application of
such provision to persons other than those as to whom it is held invalid or
unenforceable, is not to be affected and each provision of this Agreement is
valid and enforceable to the fullest extent permitted by law.

                              27.  BINDING EFFECT

                            -----------------------

In the event that TRITON desires to add equipment for new services under a new

in accordance with Section 2.3), TRITON will cooperate with CROWN to identify
and resolve any non-compliance with FCC exposure limits prior to construction or
as required by the FCC.

                           ------------------------

CROWN agrees not to permit any subsequent installation and/or modification on or
to the Site if such installation and/or modification would put any user of the
Site into non-compliance with the FCC's exposure limits for radio frequency
radiation. CROWN further agrees to limit access to the general public in areas
where the FCC's exposure limits are exceeded and agrees to post appropriate
signs warning the general population of such limited access. CROWN also agrees
to create and maintain a site safety plan including limits to RFE exposure as
required by OSHA.

the safety plans to its employees who have the potential to be exposed to RF
emissions in excess of FCC prescribed limits; and, (iii) its employees have been
directed to comply with the safety plan. Furthermore, CROWN and TRITON agree

                                  EXHIBIT C-4

                    SITE ACQUISITION (A & B SITES AS NOTED)


1. GENERAL (A SITES)

   1.1.  CROWN shall coordinate closely all site acquisition work with any Third
         Party and TRITON.

   1.2.  CROWN shall coordinate (and attend if necessary) with owners, TRITON,
         and contractors to provide site access for drive tests, RF evaluation,
         construction evaluations, or any other reasonable evaluation.

   1.3.  CROWN shall provide an Inventory (RF Emissions Inventory), to the
         extent reasonably possible, of all antennas and microwave dishes on
         collocation sites providing the carrier, technology, number of
         channels, transmit and receive frequency, power, antenna gain and type.
         As part of this inventory CROWN shall provide a sketch locating
         (dimensioning) each antenna or microwave dish on the structure
         including rad center. CROWN is not obligated to climb any antenna
         support facilities or perform any tower mapping to fulfill its
         obligation under this Section.

2. LEASING AND SITE ACQUISITION (A SITES)


   2.1.  CROWN will use CROWN's standard form of lease Agreement as approved by
         TRITON. CROWN will pursue raw land candidates only when such candidates
         are a better choice from a cost and time to market prospective as
         defined by TRITON, or as a backup candidate. Search rings where there
         are better choice candidates (candidates better than raw land from a
         time to market prospective) will be removed from the scope of this
         contract and completed under the Site Development Agreement between
         TRITON and CROWN dated November 12,1998, if an A site, or be removed
         from the scope of this contract and completed by others if a B site.

48
<PAGE>
 
   2.2.  TRITON shall select one primary and one secondary candidate site per
         search area for which CROWN shall secure a leasehold or other ownership
         interest in the primary and the secondary if so requested by TRITON. At
         its sole discretion, TRITON may reduce the required three candidate
         sites per search area to one or two sites, as well as require two
         leasehold interests to be secured.

   2.3.  CROWN shall provide a lease summary that provides a summary of all
         changes to CROWN's standard lease, all language that is not consistent
         with CROWN's standard lease in the case of an Owner lease, all business
         terms including but not limited to rate, escalation, access limitations
         and construction requirements, and a search area analysis that clearly
         identifies why the lease should be accepted by TRITON.

   2.4.  CROWN shall identify and procure any additional easements or secondary
         ground leases needed for ingress or egress to each site.

3. TITLE & OWNERSHIP (A SITES)

   3.1.  Due diligence with respect to title of all sites to be acquired by
         TRITON (by lease, purchase or otherwise) shall be performed at the
         option of TRITON as follows:

                      Environmental Policy Act.

        1.1.4.  Site Reconnaissance

            1.1.4.1.  A site reconnaissance will be conducted to obtain
                      information indicating the likelihood of identifying
                      recognized environmental conditions in connection with the
                      property. An environmental professional will visit the
                      site and visually and physically observe the property and
                      any structures on the property. The interiors of any
                      structures will be inspected. The methodology used and any
                      limitations to the observations will be documented. Uses
                      and conditions to be evaluated include current and past
                      use of the property and adjoining properties and
                      surrounding area; geologic, hydrogeologic, hydrologic, and
                      topographic conditions; structures; roads; potable water
                      supply; sewage disposal; hazardous substances to include
                      asbestos and petroleum products; storage tanks; odors;
                      pools of liquid; drums; containers; polychlorinated
                      biphenyls (PCBs); heating/cooling; stains or corrosion;
                      drains and sumps; pits, ponds, or lagoons; stained soil or
                      pavement; stressed vegetation; solid waste; waste water;
                      wells; and septic systems. In addition, threatened or
                      endangered species, and wetlands will be identified during
                      the site reconnaissance.

        1.1.5.  Interviews

            1.1.5.1.  An environmental professional will conduct interviews with
                      the property owner and occupants and local government
                      officials to obtain information indicating recognized
                      environmental conditions in connection with the property.
                      The information sought during the interviews will be the
                      same as the uses and conditions to be observed during the
                      site reconnaissance. The transaction screen questionnaire
                      in ASTM Standard E 1528-93 Environmental Site Assessments:
                      Transaction Screen Process will be used during the
                      interviews. Prior to the site visit the property owner,
                      site manager, or user will be contacted to obtain any
                      helpful documents, such as environmental audit reports,
                      environmental permits, registrations for

2.   At TRITON's option and expense, CROWN will oversee and cause to be
     performed activities required to complete the Environmental Screening
     requirement on radio frequency emissions to determine whether the proposed
     facilities are located where an operator or transmitter would cause human
     exposure to levels of radio frequency radiation in excess of the limits
     specified in Subsections 1.1310 and 2.1093, 47 C.F.R. (Applications to the
     FCC for construction permits, licenses to transmit or renewals thereof,
     equipment authorizations or modifications in existing facilities must
     contain a statement confirming compliance with the radio frequency limits
     unless the facility, operation or transmitter is categorically excluded as
     discussed in Subsection 1.1307.  Technical information showing the basis
     for this statement must be submitted to the FCC upon request.)  This
     particular Environmental Screening requirement shall be sufficient to
     uncover the impact or potential impact of any such jurisdictional
     requirements, including but not limited to, regulatory filings, hearings,
     approvals, and/or fees, site sampling, testing, or relocation of the site
     requirements.

3.   CROWN agrees that the results of any and all Environmental Screening
performed by sub-contractor or third party ("Third Party") shall be timely
reported to TRITON.  CROWN acknowledges that the timely reporting of such
information may influence the site acquisition decision, and CROWN shall pro-
actively work in good faith with TRITON to arrive at the optimal site
acquisition decision in light of such information.  CROWN agrees to seek
indemnification for TRITON from the Third Party for any costs, including
reasonable attorney fees associated with any environmental remediation, fine or
other penalty imposed on TRITON as the direct or indirect result of Third
Party's failure to detect such impact or requirement as described in this
Exhibit C-6.  Should CROWN not obtain this indemnification for TRITON in
CROWN/Third party agreement, CROWN agrees to indemnify TRITON for any costs,
including reasonable attorney fees associated with any environmental
remediation, fine or other penalty imposed on TRITON as the direct or indirect
result of Third party's failure to detect such impact or requirement as
described in this Exhibit C-6.

          (3)  Each of the Company and each of its Subsidiaries is duly
qualified to do business in each jurisdiction where the character of its
properties owned or held under lease or the nature of its activities makes such

"Claim") for indemnification under the terms of Sections 8.3, 8.4, 8.5 or 8.6.

prejudiced by reason of such delay or failure. The Indemnified Party shall have
the right to approve any counsel selected by the Indemnifying Party and to

unreasonably delayed or withheld (unless such settlement provides only, as to
the Indemnified Party, the payment of money damages actually paid by the
Indemnifying Party and a complete release of the Indemnified Party in respect of
the claim in question). Notwithstanding any of the foregoing to the contrary,
the provisions of this Article VIII shall not be construed so as to provide for

limited to, promptly furnishing the Indemnified Party with copies of all
material documents filed or served in connection therewith.

          (3)  In the event that the Indemnifying Party fails to assume the
defense of any Claim within ten Business Days after receiving written notice
thereof, the Indemnified Party shall have the right, subject to the Indemnifying
Party's right to assume the defense pursuant to the provisions of this Article
                                                                       --------
VIII, to undertake the defense, compromise or settlement of such Claim for the

Indemnified Party any of its reasonable attorneys' fees and other costs and
expenses incurred in connection with the defense of any such action or
proceeding. Each Indemnified Party shall agree in writing prior to any such
advancement that, in the event he or it receives any such advance, such
Indemnified Party shall reimburse the Indemnifying Party for such fees, costs
and expenses to the extent that it shall be determined that he or it was not
entitled to indemnification under this Article VIII.

                       ---------------------------------

                           NATURE OF THE ENGAGEMENT
                           ------------------------


          3.01  SCOPE OF WORK.  Client hereby engages American Tower to perform
                -------------                                                  
the Work and Services as set forth in Exhibit A, "Scope of Work".  American
Tower hereby accepts such engagement in accordance with the terms and conditions
of this Agreement.

In addition to the scope of services defined in the Exhibits, American Tower is
responsible for every item identified in the Responsibility Matrix (Exhibit C-6)
as a American Tower responsibility. American Tower shall devote such time and
resources as are necessary to ensure proper and expeditious completion of its
duties hereunder and shall make available to Client the full range of its
expertise and experience in constructing wireless systems, using the methods for
wireless site development that will ensure speed of delivery and simplification
of the required work.

The scope includes approximately 115 Build to Suit Sites and includes the Site
Development work associated with these Build to Suit Sites.  Any Sites that
become collocations in accordance with Exhibit A-4, paragraph 2.1 will be
removed from the scope of this Agreement and be completed under the separate
Site Acquisition, Zoning and Construction Supervision Master Services Agreement,
Amendment No. 1, dated September 30, 1998, between American Tower and Client.

          3.02  PAYMENTS.  American Tower's compensation for the Project or any
                --------                                                       
part thereof shall be as set forth in Exhibit B, "Payments".

          3.03  SCHEDULE.
                ---------

Within 21 days after execution of this Agreement, Client and American Tower
shall agree upon the schedule for the completion of Services on a site-by-site
basis which will replace Exhibit C to this Agreement. The schedule will contain
milestone dates for completion by American Tower of the following milestones:
Site Selection, Site Acquisition, Site Zoning, Building Permit, Construction
Start and Construction Complete.  This Agreement shall terminate upon notice by
either party to the other if the parties are unable, after good faith
negotiations, to agree to a schedule within the allotted 21 days.
Notwithstanding the foregoing, American Tower agrees to proceed working under
this Agreement, including deploying necessary personnel, immediately after
execution of this Agreement as set forth in Exhibits C-4 and C-5, provided,
however, that Client shall reimburse American Tower for all reasonable costs
incurred in so proceeding, should the Agreement be terminated on account of the
parties' inability to agree on a schedule as provided above.

Following approval of the schedule by Client, American Tower shall thereafter,
for the term of this Agreement, provide Client with not less than a written
weekly report outlining the progress made to attain the previously-agreed to
schedule, which reports must include the information required by Exhibit A-12.

                                       5
<PAGE>
 
Any proposed change in schedule which results in a time extension of one week or
greater on an individual site basis shall be clearly noted and the reasons
therefore shall be explained in writing. Client may, in its sole discretion,
agree to a time extension from the detailed schedule originally provided.
Notwithstanding the foregoing, American Tower shall be entitled to a reasonable
time extension for any delay caused by Client, and delay caused by an event of
Force Majeure shall be governed by Article 9 of the Agreement. American Tower
shall attend all project meetings reasonably requested by Client. American Tower
further agrees to the maximum average cycle times set forth in Exhibit C-2.

Within 5 days after execution of this agreement, American Tower will provide an
Organization Chart and Staffing Plan that will replace Exhibit C-5.  Within 10
days after execution of this agreement American Tower will provide a revised
Exhibit C-4 indicating at minimum all Managers by name.  Within 20 days of the
execution of this agreement Exhibit C-4 will be revised by American Tower to
indicate the names of all personnel set forth on Exhibit C-4.

The term of this Agreement shall commence on the Effective Date, and shall
continue until (i) terminated as provided herein; or (ii) performance of the
Agreement is extended as a result of an Excusable Delay.

          3.04  WITHDRAW OF SITES.  If American Tower has not completed Services
                -----------------                                               
in accordance with the Schedule identified in Exhibit C or the Maximum Average
Cycle Times identified in Exhibit C-2, with respect to a Site, then, in addition
to any other remedy allowed under the Agreement, Client may withdraw that Site
if American Tower fails to cure such default within fifteen (15) days of receipt
of written notice thereof; provided, however, that if such failure shall
necessitate longer to cure than fifteen (15) days, then such cure period shall
be extended for such time as is reasonably necessary to cure such default (not
to exceed sixty (60) days). American Tower will not be compensated for work
performed prior to such withdrawal.

          3.05  RELATIONSHIP.  The parties agree to reasonably cooperate with
                ------------                                                 
each other in the performance of this Agreement.  Client and American Tower, in
the performance of this Agreement, will be acting in their individual capacities
and not as employees, partners, joint venturers, agents or associates of one
another.  In the performance of this Agreement, American Tower is, and shall at
all times during the term of this Agreement be, an independent contractor.
Nothing contained in this Agreement creates the relationship of a joint venture,
partnership, association or agency between the parties.  No party shall have any
authority to bind or otherwise obligate the other.  Persons retained by either
party as employees or agents shall not be deemed to be employees or agents of
the other party.

                ----------------- 

                (A) American Tower shall employ only competent and able

obligations under this Agreement.

                (B)  American Tower will be responsible to Client for the
actions and conduct of all American Tower's employees, agents, consultants,
advisors, contractors and subcontractors employed in the performance of this
Agreement, including their compliance with Governmental Requirements.

                (C)  Notwithstanding the foregoing, Client has the right at any
time upon written notice to require the removal of any employee of American
Tower or subcontractor utilized or supervised by American Tower for reasonable
cause in Client's sole discretion. Resumes will be provided for review and
approval prior to American Tower's employees starting work on this project.
American Tower will not remove any personnel once assigned to the project and
accepted by Client without prior written agreement with Client, except for
personal and compassionate reasons upon mutual agreement by American Tower and
Client. Further, personnel involved in site acquisition activities may be
reassigned at American Tower's discretion and Client's consent, after five (5)
or fewer site rings remain to be administered.

          3.07  QUALITY STANDARD.  American Tower agrees to perform its
                ----------------                                       
obligations and furnish its Work and Services hereunder properly, diligently,
and in good faith, in accordance with the standards of its industry, to Client's
reasonable satisfaction and in accordance with all applicable Governmental
Requirements.  American Tower shall implement quality control procedures
sufficient to ensure compliance with the Specifications and shall otherwise
maintain quality standards for the Work and Services at least equal to the
normal quality standards applied by American Tower prior to the date of this
Agreement.

          3.08  EXPANSION IN SCOPE OF PROJECT.  The parties may agree to add
                -----------------------------                               
additional cell sites to this Agreement (the "Additional Sites"), within
Georgia, North Carolina, and south Carolina, on the same terms and conditions as
are applicable to the original Sites.

          Client may make changes at any time to the general scope of the
Services contained herein only by means of a written order (a "Change Order")
issued by American Tower and approved by Client. Any Change Order that exceeds
the scope of Services and which requires additional services on the part of
American Tower may result in an adjustment of the price to be paid to American
Tower. American Tower shall, upon receipt of a written request for a Change
Order from Client, provide Client with an estimate of additional charges
required to complete the proposed Change Order. Prior to commencement of
additional work, the proposed Change Order shall be approved in writing by a
Client representative. Any charges for additional work commenced by American
Tower without a written Change Order approved by a Client representative may be
denied by Client, in full or in part, in its sole discretion.

after receipt of any such proposal as to any potential cell site, Client shall

before Completion to examine Work already completed, American Tower shall, on

           (A)  Either party shall be in default under this Agreement if the
party fails to perform any material duty or obligations under this Agreement and
does not cure or remedy such failure to perform within fifteen (15) days after
receipt of written notice with respect thereto; provided, however, that, if such
                                                --------  -------               
failure to perform shall necessitate longer to cure than fifteen (15) days, then
such cure period shall be extended for such time as is reasonably necessary to
cure such failure to perform (not to exceed 60 days), but only so long as such
efforts to cure are commenced within fifteen (15) days after receipt of written
notice from the other party and thereafter proceed diligently and in good faith.
In no event shall the time within which a party may cure a default in the
payment of money be extended beyond the initial fifteen (15) day period in this
Section.

           (B)  Upon the occurrence of a default the nondefaulting party may
pursue any and all remedies available under applicable law and any one or more
of the following remedies, separately or concurrently or in any combination,
without further notice or demand whatsoever:

accrued under this Agreement prior to the effective date of such termination.

           (D)  Client may terminate this Agreement and any or all Site Leases
executed in connection herewith upon executing an agreement with American Tower

withheld or delayed.  Failure of the parties to agree on the appropriate
adjustment in a Site Schedule or the Project Schedule shall be treated as a

               mediator may meet with the affected parties separately.

               (III)  No minutes shall be kept and the comments and/or findings
               of the mediator, together with any written statements prepared,
               shall be non-binding, confidential, and without prejudice to the

               the parties agree otherwise in writing.  If the dispute is
               settled through the mediation process, it will be implemented by
               written agreement signed by all affected parties.  The cost of
               mediation shall be borne equally by the parties.

       (B)  ARBITRATION:
            ----------- 


               (I)  As a condition precedent to arbitration, the parties shall
               endeavor to resolve their disputes using business-like
               negotiation and mediation, as provided for above.  Any claim,
               dispute, or controversy arising out of or relating to the
               Agreement not so resolved shall be decided by arbitration in
               accordance with the Commercial Rules of the American Arbitration
               Association.  The locale for such arbitration shall be the City
               of Philadelphia, Commonwealth of Pennsylvania, and the demand for
               arbitration must be filed with, and the arbitration administered
               by, the Atlanta Tribunal of the American Arbitration Association.
               The foregoing agreement to arbitrate shall be specifically
               enforceable in any court of competent jurisdiction.  Upon its
               request, a party shall be entitled to 

                                       20
<PAGE>
 
               consolidation or joinder of any arbitration related arbitrations
               involving other parties. The award rendered by the arbitrators
               shall be final and judgment may be entered upon it in accordance
               with applicable law in any court of competent jurisdiction.

               (II)   Any demand for arbitration hereunder must be filed within
               a reasonable time of the occurrence of the facts giving rise to
               the dispute. In no event shall any demand for arbitration be
               filed after the running of any applicable statutes of limitation.

               (III)  The parties shall promptly proceed with performance of
               their respective obligations under the Agreement pending
               resolution of any claim or dispute, and failure to do so is a
               material breach of the Agreement.

     10.11  ENTIRE AGREEMENT.  This Agreement contains the entire agreement of
            ----------------

     preference to sites available under Client's existing master lease
     agreements entered into by Client ("Master Leases"). If American Tower
     cannot utilize sites under Master Leases, written documentation must be
     provided to Client giving justification as to why sites under Master Leases
     cannot be used.

4.   American Tower will visit each search area for the purpose of identifying
     candidates, catalog ALL viable candidates, prioritize the candidates, and
     submit the 3 most viable candidates for Client approval.

5.   A Viable Candidate is a site that meets the following criteria:

     5.1. The Candidate meets or exceeds RF design requirements based on
          acceptable drive tests and/or propagation model results.

          in accordance with local ordinances within the agreed upon timeline
          set forth in Exhibit C.

          and can be completed within the time limits set forth in Exhibit C.

6.   American Tower will prioritize the candidates submitted based on leasing
     and zoning prognosis to identify the relative viability of the candidates.
     American Tower will not submit candidates that cannot be leased and zoned
     within the agreed upon timeline set forth in Exhibit C.

7.   American Tower will identify a minimum of three (3) viable candidates for
     each search area within 20 work days after receipt of the search area from
     Client. American Tower shall have an additional 10 days to identify
     potential candidates for additional search areas if Client has delivered
     more than 50 search areas to American Tower within a calendar week. If
     three (3) such candidates are not available, American Tower will furnish to
     Client a written explanation of American Tower's reason(s) why unavailable.

8.   American Tower will provide search area reports containing the following
     minimum information:

     established scheduled time lines in accordance with this Agreement.

12.  Notwithstanding the foregoing, upon request from American Tower, Client may
     modify its requirements to decrease the number of site candidates for each
     search area to less than three, if Client reasonably believes such
     reduction will facilitate the objectives of the Agreement.

                                  EXHIBIT A-4

                               SITE ACQUISITION


1.   GENERAL
     -------
     1.1. American Tower shall coordinate closely all site acquisition work with
          any Third Party and Client.

     1.2. American Tower shall coordinate (and attend if necessary) with owners
          and Client American Towers or Staff to provide site access for drive
          tests, RF evaluation, construction evaluations, or any other
          reasonable evaluation.

     1.3. American Tower shall provide an Inventory (RF Emissions Inventory), to
          the extent reasonably possible, of all antennas and microwave dishes
          on collocation sites providing the carrier, technology, number of
          channels, transmit and receive frequency, power, antenna gain and
          type. As part of this inventory American Tower shall provide a sketch
          locating (dimensioning) each antenna or microwave dish on the
          structure including rad center. American Tower is not obligated to
          climb any antenna support facilities or perform any tower mapping to
          fulfill its obligation under this Section.

2.   LEASING AND SITE ACQUISITION
     ----------------------------
     2.1. If the site is to be acquired by lease, American Tower will be
          responsible for securing proper execution by the site owner/landlord
          of the appropriate form of lease with respect to each proposed site.
          American Tower must use best efforts to use Client's standard forms of
          Master Lease Agreement, PCS Site Agreement or other lease forms to
          acquire rights to proposed sites and will use lease agreements
          provided by an owner/landlord only as a last resort. American Tower
          must also use best efforts to use sites available under negotiated
          Master Leases. American Tower will obtain and follow all negotiating
          guidelines provided by Client and augment and formalize those
          guidelines for distribution and training of Site Acquisition
          personnel.

     2.2. American Tower will use Client's standard form of lease Agreement as
          approved by Client. American Tower will pursue raw land candidates
          only when such candidates are a better choice from a cost and time to
          market prospective as defined by Client, or as a backup candidate.
          Search rings where there are better choice candidates (candidates
          better than raw land from a time to market prospective) will be
          removed from the scope of this Agreement and be completed under the
          separate Site Acquisition, Zoning and Construction Supervision Master
          Services Agreement, Amendment No. 1, dated September 30, 1998, between
          American Tower and Client.

     2.3. Client shall select one primary and one secondary candidate site per
          search area for which American Tower shall secure a leasehold or other
          ownership interest in the primary and the secondary if so requested by
          Client. At its sole discretion, Client may 

                                       30
<PAGE>
 
          reduce the required three candidate sites per search area to one or
          two sites, as well as require two leasehold interests to be secured.

     2.4. American Tower shall provide a lease summary that provides a summary
          of all changes to Client's standard lease, all language that is not
          consistent with Client's standard lease in the case of an Owner lease,
          all business terms including but not limited to rate, escalation,
          access limitations and construction requirements, and a search area
          analysis that clearly identifies why the lease should be accepted by
          Client.

     2.5. American Tower shall identify and procure any additional easements or
          secondary ground leases needed for ingress or egress to each site.

3.   TITLE & OWNERSHIP
     -----------------
     3.1. Due diligence with respect to title of all sites to be acquired by
          Client (by lease, purchase or otherwise) shall be performed at the
          option of Client as follows:

          3.1.1.  Acquire an ownership and encumbrance report ("O&E Report")
                  from a nationally known title insurance company satisfactory
                  to Client which sets forth the same information as required
                  for an ALTA title insurance policy described below relating to
                  the proposed site (to the extent ascertainable by the title
                  company);

          3.1.2.  Acquire an ALTA title insurance policy on ground leases,
                  insuring that Client is the owner of the leasehold estate
                  created by the lease covering the site in question, such
                  policy to be issued by a nationally recognized title insurance
                  company acceptable to Client and to be in such amount and to
                  contain such exceptions to title as are satisfactory to Client
                  in Client's sole discretion and in this regard the title
                  insurance requirements to be followed by American Tower with
                  respect to the insuring of the leasehold shall be
                  substantially the same as the title insurance requirements set
                  forth by Client.

     3.2. American Tower shall manage all title curative work identified in the
          title report analysis.

4.   THIRD-PARTY SERVICES
     --------------------
     4.1  Perform or coordinate with the third party to ensure that all
          applicable due diligence tests and studies have been performed prior
          to the start of site construction to determine to Client's reasonable

           1.1.1.   Schedule: All Phase I shall be completed within ten (10)
                    business days from "Notice to Proceed".

           1.1.2.   The purpose of a Phase I ESA is to identify and define
                    recognized environmental conditions within the range of
                    contaminants within the scope of the Comprehensive
                    Environmental Response, Compensation, and Liability Act
                    (CERCLA) and petroleum products. As such, the Phase I ESA
                    satisfies one of the requirements to qualify for the
                    innocent Companydefense to CERCLA liability: that is, the
                    practices that constitute "all appropriate inquiry into the
                    previous Ownership and uses of the property consistent with
                    good commercial or customary practice," as defined in 42 USC
                    9601(35)(B). The ESAs will be conducted in accordance with
                    American Society for Testing and Materials (ASTM) Standard:
                    E 1527-94 Practice for Environmental Site Assessments for
                    Commercial Real Estate, and will consist of four components:
                    records review, site reconnaissance, interviews, and a Phase
                    I report. In addition, the Federal Communication
                    Commission's (FCC) checklist for the National Environmental
                    Policy Act (NEPA) will be completed as part of the Phase I
                    ESA report. Each of the Phase I ESA components is discussed
                    in the following subsections.

          8.   Qualifications/Signatures of Environmental Professionals

     1.1.6.2  The report appendices will include the USGS map; the environmental
              database search report; any documentation of past use, such as
              property tax files and land title records; photographs; any
              documentation such as previous environmental reports; and copies
              of the ESA transaction screen questionnaire used during
              interviews.

     1.1.6.3  The FCC checklist for NEPA investigations will also be provided as
              an appendix in the Phase I ESA report. This FCC checklist will
              include answering the following questions:

              1.   Is the proposed facility located in an officially designated
                   wilderness area?
              2.   Is the proposed facility located in an officially designated
                   wilderness preserve?
              3.   Will the proposed facility likely affect threatened or
                   endangered species or designated critical habitats?
              4.   Will the proposed facility likely jeopardize the continued
                   existence of any proposed endangered or threatened species?
              5.   Will the proposed facility likely result in the destruction
                   or adverse modification of proposed critical habitats (as
                   determined by the Endangered Species Act of 1973)?
              6.   Will the facility affect districts, sites, buildings,
                   structures or objects, significant in American history,
                   architecture, archeology, engineering or culture, that are
                   listed (or eligible for listing) in the National Register of
                   Historic Places?
              7.   Will the facility affect Indian religious site(s)?
              8.   Is the facility located in a flood plain?
              9.   Will construction of the proposed facility involve
                   significant change in surface features (e.g., wetland fill,
                   deforestation or water diversion)?
              10.  Is the proposed facility located in a residential
                   neighborhood and is required to be equipped with high
                   intensity white lights (as defined by local zoning law)?

     1.1.6.4  The RF Exposure Screening Under NEPA will not be included as part
              of this work. Specifically the following questions will not be
              answered.

                    1.   Will the proposed NON-ROOFTOP facility equal or exceed
                         total power (of all channels) of 2000 Watts ERP (3280
                         Watts EIRP) and have antennae located less than 10
                         meters above ground level?

                    2.   Will the proposed ROOFTOP facility equal or exceed
                         total power (of all channels) of 2000 Watts ERP (3280
                         Watts EIRP)?

2.   At Client's option, American Tower will oversee and cause to be performed
     activities required to complete the Environmental Screening requirement on
     radio frequency emissions to determine whether the proposed facilities are
     located where an operator or transmitter would cause human exposure to
     levels of radio frequency radiation in excess of the limits specified in
     Subsections 1.1310 and 2.1093, 47 C.F.R. (Applications to the FCC for
     construction permits, licenses to transmit or renewals thereof, equipment
     authorizations or modifications in existing facilities must contain a
     statement confirming compliance with the radio frequency limits unless the
     facility, operation or transmitter is categorically excluded as discussed
     in Subsection 1.1307.  Technical information showing the basis for this
     statement must be submitted to the FCC upon request.)  This particular
     Environmental Screening requirement shall be sufficient to uncover the
     impact or potential impact of any such jurisdictional requirements,
     including but not limited to, regulatory filings, hearings, approvals,
     and/or fees, site sampling, testing, or relocation of the site
     requirements.

3.   American Tower agrees that the results of any and all Environmental
     Screening performed by sub-contractor or third party ("Third Party") shall
     be timely reported to Client. American Tower acknowledges that the timely
     reporting of such information may influence the site acquisition decision,
     and American Tower shall pro-actively work in good faith with Client to
     arrive at the optimal site acquisition decision in light of such
     information. American Tower agrees to seek indemnification for Client from
     the Third Party for any costs, including reasonable attorney fees
     associated with any environmental remediation, fine or other penalty
     imposed on Client as the direct or indirect result of Third Party's failure
     to detect such impact or requirement as described in this Exhibit A-6.
     Should American Tower not obtain this indemnification for Client in
     American Tower/Third party agreement, American Tower agrees to indemnify
     Client for any costs, including reasonable attorney fees associated with
     any environmental remediation, fine or other penalty imposed on Client as
     the direct or indirect result of Third party's failure to detect such
     impact or requirement as described in this Exhibit A-6.
