ITEM 1. BUSINESS

INTRODUCTION

        Western Wireless Corporation ("Western Wireless") provides wireless
communications services in the United States principally through the ownership
and operation of cellular and personal communications services ("PCS") systems.
The cellular operations are primarily in rural areas and the PCS operations are
primarily in urban areas due to Western Wireless' belief that there are certain
strategic advantages to operating each technology in these respective areas. As
of December 31, 1998, Western Wireless provides cellular services in 17 western
states under the Cellular One(R) brand name. Western Wireless provides PCS
services through its 80.1% ownership in VoiceStream Wireless Corporation
("VoiceStream"). VoiceStream had commenced commercial operations in ten markets
under the VoiceStream(R) brand name as of December 31, 1998 (an eleventh market
commenced commercial operations in February 1999). VoiceStream PCS services are
also offered in three additional markets in conjunction with joint ventures (a
fourth market commenced commercial operations in February 1999).

        On February 8, 1999, Western Wireless announced its intention to
separate VoiceStream from Western Wireless' other operations (the "Spin-off").
Western Wireless has received a favorable ruling by the Internal Revenue Service
for a tax free spin-off, and the approval by its board of directors to take the
necessary steps to complete the Spin-off. Western Wireless will distribute all
of its interest in VoiceStream to its shareholders upon the Spin-off. Although
VoiceStream has been operated separately from Western Wireless' other operations
and has been a separate legal entity since its inception, the Spin-off will
establish VoiceStream as a stand-alone entity with objectives separate from
those of Western Wireless. The Spin-off is subject to numerous conditions
including, among others, the receipt of certain government and third party
approvals. There is no assurance that such conditions will be met to complete
the Spin-off.

BACKGROUND

THE WIRELESS COMMUNICATIONS INDUSTRY

        OVERVIEW

        Wireless communications systems use a variety of radio frequencies to
transmit voice and data. Broadly defined, the wireless communications industry
includes one-way radio applications, such as paging or beeper services, and
two-way radio applications, such as cellular, PCS and Enhanced Specialized
Mobile Radio ("ESMR") networks. Each such application is licensed in a distinct
radio frequency block.


                                       3
<PAGE>   4

        Since its introduction in 1983, wireless service has grown dramatically.
As of June 30, 1998, according to the Cellular Telecommunications Industry
Association ("CTIA") there were over 60.8 million wireless subscribers in the
United States, representing a penetration rate of 22.4%.

        In the wireless communications industry, there are two principal
frequency bands licensed by the Federal Communications Commission ("FCC") for
transmitting two way voice and data signals, "cellular" and "PCS." Cellular
systems are generated at 824 to 899 MHz and can be either analog or digital.
Although all cellular systems provide analog capabilities, digital technology
has been introduced by most carriers in urban markets. Analog technology has
several limitations, including lack of privacy and limited capacity. Digital
systems convert voice or data signals into a stream of digits that is compressed
before transmission, enabling a single radio channel to carry multiple
simultaneous signal transmissions. This enhanced capacity, along with
improvements in digital signaling, allows digital-based wireless technologies to
offer new and enhanced services, such as greater call privacy, and robust data
transmission features, such as "mobile office" applications (including
facsimile, electronic mail and wireless connections to computer/data networks,
including the internet).

        PCS is a term commonly used in the United States to describe a portion
of radio spectrum from 1850 to 1990 MHz. PCS spectrum was auctioned by the FCC
in six frequency blocks (A-F) beginning with the A and B Blocks in late 1994 and
1995. In late 1995 and in 1996 the C Block was auctioned and the FCC concluded
simultaneous auctions of the D, E and F Blocks in 1997. In 1999, the FCC intends
to reauction portions of the C, D, E and F Blocks returned to the FCC. This
portion of radio spectrum is to be used by PCS licensees to provide wireless
communications services. PCS competes directly with existing cellular telephone,
paging and specialized mobile radio ("SMR") services. PCS includes features
that are not generally offered by analog cellular providers, such as data
transmissions to and from computers, advanced paging services and facsimile
services. In addition, wireless providers may eventually offer mass market
wireless local loop applications in competition with wired local communications
services.

OPERATION OF WIRELESS COMMUNICATIONS SYSTEMS

        Wireless communications system service areas, whether cellular or PCS,
are divided into multiple cells. Due to the frequencies in which they operate, a
single cell in a cellular system generally transmits over a wider radius than a
comparable PCS cell. In both cellular and PCS systems, each cell contains a
transmitter, a receiver and signaling equipment (the "Cell Site"). The Cell Site
is connected by microwave or landline telephone lines to a switch that uses
computers to control the operation of the wireless communications system for the
entire service area. The system controls the transfer of calls from cell to cell
as a subscriber's handset travels, coordinates calls to and from handsets,
allocates calls among the cells within the system and connects calls to the
local landline telephone system or to a long distance telephone carrier.
Wireless communications providers establish interconnection agreements with
local exchange carriers and inter-exchange carriers, thereby integrating their
system with the existing landline communications system.

        Because the signal strength of a transmission between a handset and a
Cell Site declines as the handset moves away from the Cell Site, the switching
office and the Cell Site monitor the signal strength of calls in progress. When
the signal strength of a call declines to a predetermined level, the switching
office may "hand off" the call to another Cell Site where the signal strength is
stronger. If a handset leaves the service area of a cellular or PCS system, the
call is disconnected unless there is a technical connection with the adjacent
system.

        Wireless system operators normally agree to provide service to
subscribers from other compatible wireless systems who are temporarily located
in or traveling through their service areas in a practice called "roaming."
Agreements among system operators provide that the carrier that normally
provides services to the roaming subscriber pays the serving carrier at rates
prescribed by the serving carrier. Analog cellular handsets are functionally
compatible with cellular systems in all markets within the United States. As a
result, analog cellular handsets may be used wherever a subscriber is located,
as long as a cellular system is operational in the area and necessary roaming
arrangements exist. Although PCS and cellular systems utilize similar
technologies and hardware, they operate on different frequencies and use
different technical and network standards. Dual mode phones, however, make it
possible for users of one type of system to "roam" on a different type of system
outside of their service area.

        PCS systems operate under one of three principal digital signal
transmission technologies, or standards, that have been deployed by various
operators and vendors for use in PCS systems: GSM, TDMA or CDMA. GSM is the most
widely used digital wireless standard in the world serving over 120 million
subscribers in approximately 130 


                                       4
<PAGE>   5

countries. A benefit associated with GSM technology is its use of an open system
architecture that allows operators to purchase network equipment from a variety
of vendors that share standard interfaces for operation.

        GSM and TDMA are both based upon time-division of spectrum and are
currently incompatible with each other and with CDMA. Accordingly, a subscriber
of a system that utilizes GSM technology is currently unable to use a GSM
handset when traveling in an area not served by GSM-based PCS operators, unless
the subscriber carries a dual-mode handset that permits the subscriber to use
the analog cellular system in that area. Under a memorandum of understanding
between GSM operators in the United States and Canada and the association of
TDMA operators in the United States and Canada, there are plans to promote the
interoperability of GSM and TDMA standards.

        The TDMA-based PCS standard offers the same features and services
offered by the time division-based digital cellular standard currently in use by
certain cellular operators in the United States, including AT&T Wireless
Services Inc. ("AT&T Wireless") and Southwestern Bell Wireless ("Southwestern
Bell"). Both the CDMA- and TDMA-based PCS standards use a closed system
architecture that will limit PCS operators' choices of equipment vendors. The
CDMA standard is the most widely adopted digital standard in the United States.
CDMA-based PCS systems offer the same features and services offered by
CDMA-based cellular systems.

THE CELLULAR BUSINESS OF WESTERN WIRELESS

        After the Spin-off Western Wireless will continue to operate domestic
cellular services, paging and competitive local exchange services in select U.S.
markets and international telecommunications operations through joint ventures.

        GENERAL

        Western Wireless operates high quality cellular systems in 17 western
states, serving over 660,000 cellular subscribers under the Cellular One brand
name. To support its rapidly growing subscriber base, Western Wireless operates
and maintains extensive centralized management, back office functions and a call
center in the state of Washington. Western Wireless also operates paging systems
in eight western states serving 35,900 paging customers at December 31, 1998.

        Through international joint ventures, Western Wireless has interests in
(and in certain cases manages) wireless licenses in several foreign countries,
including Ghana, Iceland, Haiti, Croatia and the Republics of Latvia and
Georgia. In addition, Western Wireless has interests in entities which have made
wireless license applications in certain other foreign countries. Western
Wireless does not own a controlling interest in any of these joint ventures. As
such each of these joint ventures is accounted for using the equity method as of
December 31, 1998. A joint venture which Western Wireless controls has been
notified by the Irish Government that it is the preferred applicant for a
DCS-1800/GSM 900 mobile communication license in Ireland. The license has not
yet been issued, as the decision by the Irish Government is subject to a pending
legal proceeding.

        CELLULAR STRATEGY

        Western Wireless' principal focus is on the operation of cellular
systems in rural markets in the United States. Western Wireless believes that
analog cellular is the optimum technology for these rural areas because they are
less susceptible to competition and have a greater capacity for future growth
than most major markets.

        Western Wireless' operating strategy is to position itself as the
premier rural communications provider in the United States. This strategy
requires that it: (i) maintain and operate high quality systems with extensive
coverage; (ii) expand operations through increased subscriber growth and usage;
(iii) utilize centralized management, back office functions and its own sales
force to improve operating efficiencies and generate greater economies of scale;
and (iv) acquire additional cellular licenses in rural areas.

        Western Wireless is implementing its strategy by: (i) continually
upgrading and maintaining its present systems to allow for more functionality
and quality performance; (ii) offering a targeted range of products and services
to complement today's business and personal lifestyles at competitive prices;
and (iii) providing a superior level of customer service.


                                       5
<PAGE>   6
 

        Western Wireless has roaming arrangements with virtually every cellular
carrier in North America including roaming arrangements with certain cellular
carriers adjacent to Western Wireless' markets that provide attractive rates to
Western Wireless' customers when roaming in these surrounding areas. In
addition, Western Wireless has roaming arrangements with several wireless
service providers, including AT&T Wireless, Sprint PCS L.P. ("Sprint PCS"),
AirTouch Communications, Inc. ("AirTouch"), Southwestern Bell and U.S. West 
Wireless ("U.S. West") that allow their customers to roam in Western Wireless' 
cellular markets. Western Wireless allows PCS subscribers to roam in its 
markets through the use of dual and tri-mode handsets.

        WESTERN WIRELESS FORMATION

        Western Wireless was formed in July 1994 as the result of a business
combination (the "Business Combination") among various companies, including
Markets Cellular Limited Partnership d/b/a Pacific Northwest Cellular, a
Delaware limited partnership ("MCLP"), and General Cellular Corporation, a
Delaware corporation ("GCC"). GCC commenced operations in 1989 and MCLP was
formed in 1992. As a result of the Business Combination and a series of related
transactions, Western Wireless became the owner of all of the assets of MCLP.
Accordingly, all financial data relating to Western Wireless herein with respect
to periods after the date of the Business Combination reflect the operations of
GCC and MCLP and all such data with respect to prior periods reflect only the
operations of GCC, which, for accounting purposes, is considered Western
Wireless' predecessor.

        CELLULAR MARKETS AND SYSTEMS

        Western Wireless operates cellular systems in 16 smaller Metropolitan
Statistical Areas ("MSA") and 76 Rural Service Areas ("RSA"), and generally owns
100% of each of its cellular licenses that cover approximately 7.6 million
people. See "-- Cellular Governmental Regulation, Licensing of Cellular
Systems." Western Wireless' experience is that several inherent attributes of
RSAs and small MSAs make such markets attractive. Such attributes include high
subscriber growth rates, population bases of customers with substantial needs
for wireless communications, the ability to cover larger geographic areas with
fewer Cell Sites than is possible in urban areas, less intense competitive
environments and less vulnerability to PCS competition.

        See the summarized financial results of Western Wireless' cellular
operations in the footnotes to the consolidated financial statements located in
Part II of this Form 10-K.

        Population data in the following table is estimated for 1999 based upon
1998 estimates by Equifax Marketing Decision Systems, Inc. ("Equifax") adjusted
by Western Wireless by applying Equifax's growth factors from 1997 to 1998.

        CELLULAR PRODUCTS AND SERVICES

        Western Wireless offers its subscribers high quality cellular
communications, as well as several custom calling services, such as call
forwarding, call waiting, conference calling, voice message storage and
retrieval, data services and no-answer transfer. In addition, all subscribers
can access local government emergency services from their cellular handsets
(with no air time charge) by dialing 911. Western Wireless will continue to
evaluate new products and services that may be complementary to its wireless
operations. Western Wireless has designed several pricing options to meet the
varied needs of its customer base. Most options consist of a fixed monthly
charge (with varying allotments of included minutes, in some cases), plus
additional variable charges per minute of use. In addition, in most cases
Western Wireless separately charges for its custom calling features.

        Western Wireless provides extended regional and national service to
cellular subscribers in its markets, through its membership in North American
Cellular Network ("NACN") and other regional networking arrangements, thereby
allowing them to make and receive calls while in other cellular service areas
without dialing special access codes. NACN is the largest wireless telephone
network system in the world, linking non-wireline cellular operators throughout
the United States, Canada, Puerto Rico and the Virgin Islands. Western Wireless
also has special roaming arrangements with certain cellular carriers in areas
adjacent to Western Wireless' markets that provide Western Wireless' customers
attractive rates when roaming in these surrounding areas.

        CELLULAR MARKETING, SALES AND CUSTOMER SERVICE

        Western Wireless' sales and marketing strategy is to generate continued
net subscriber growth and increased subscriber revenues. In addition, Western
Wireless targets a customer base which it believes is likely to generate higher
monthly service revenues, while attempting to achieve a low cost of adding new
subscribers.

        Marketing - Western Wireless markets its cellular products and services
in all markets under the name Cellular One. Cellular One, the first national
brand name in the cellular industry, is currently utilized by a national
coalition of cellular licensees in 48 states with a combined estimated
population of over 115 million. The national advertising campaign conducted by
the Cellular One Group enhances Western Wireless' advertising exposure at a
lesser cost than what could be achieved by Western Wireless alone.

        Sales - Western Wireless sells its products and services through a
combination of direct and indirect channels. Western Wireless operates 165
retail sales locations under the Cellular One brand name and utilizes a direct
sales force of over 1,000 persons based out of these offices, who are trained to
educate new customers on the features of its products. Sales commissions
generally are linked both to subscriber revenue and subscriber retention, as
well as activation levels.

        Western Wireless believes that its local sales offices provide the
physical presence in local markets necessary to position Cellular One as a
quality local service provider, and give Western Wireless greater control over
both its costs and the sales process. Western also utilizes indirect sales
through an extensive network of national and local merchant and specialty
retailers. Western Wireless intends to continue to use a combination of direct
and indirect sales channels, with the mix depending on the demographics of each
particular market.

        In addition, Western Wireless acts as a retail distributor of handsets
and maintains inventories of handsets. Although subscribers generally are
responsible for purchasing or otherwise obtaining their own handsets, Western
Wireless has historically sold handsets below cost to respond to competition and
general industry practice and expects to continue to do so in the future.

        Customer Service - Customer service is a significant element of Western
Wireless' operating philosophy. Western Wireless is committed to attracting and
retaining subscribers by providing consistently superior customer service. In
Issaquah, Washington, Western Wireless maintains a highly sophisticated
monitoring and control system, a staff of customer service personnel and a
well-trained technical staff to handle both routine and complex questions as
they arise, 24 hours a day, 365 days a year. Western Wireless has announced its
intention to open a new call center in Manhattan, Kansas during 1999, to support
its growing subscriber base.

        Western Wireless implements credit check procedures at the time of sale
and continuously monitors customer churn (the rate of subscriber attrition).
Western Wireless believes that it helps manage its churn through an outreach
program by its sales force and customer service personnel. This program not only
enhances subscriber loyalty, but 


                                       8
<PAGE>   9

also increases add-on sales and customer referrals. The outreach program allows
the sales staff to check customer satisfaction, as well as to offer additional
calling features, such as voice mail, call waiting and call forwarding.

        CELLULAR SUPPLIERS AND EQUIPMENT VENDORS

        Western Wireless does not manufacture any of the handsets or Cell Site
equipment used in its operations. The high degree of compatibility among
different manufacturers' models of handsets and Cell Site equipment allows
Western Wireless to design, supply and operate its systems without being
dependent upon any single source of such equipment. The handsets and Cell Site
equipment used in the operations are available for purchase from multiple
sources, and anticipates that such equipment will continue to be available in
the foreseeable future. Western Wireless currently purchases handsets primarily
from Motorola, Inc., NEC Inc. and Nokia Telecommunications, Inc. ("Nokia") and
its Cell Site and switching equipment primarily from Northern Telecom, Inc. and
Lucent Technologies, Inc.

        CELLULAR 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. Under
current FCC rules, there may be up to seven PCS licensees in each geographic
area in addition to the two existing cellular licensees. Also, SMR dispatch
system operators have constructed digital mobile communications systems on
existing SMR frequencies, referred to as ESMR, in many cities throughout the
United States, including some of the markets in which Western Wireless operates.

        Western Wireless has one cellular competitor in each of its cellular
markets including AirTouch, Aliant Communications, Inc., CommNet Cellular Inc.,
Kansas Cellular, Southwestern Bell and United States Cellular Corporation.
Western Wireless has one PCS competitor in some of its largest markets. Western
Wireless also competes with paging, dispatch and conventional mobile telephone
companies, resellers and landline telephone service providers in its cellular
markets. Potential users of cellular systems may, however, find their
communications needs satisfied by other current and developing technologies. One
or two-way paging services that feature voice messaging and data display as well
as tone only service may be adequate for potential subscribers who do not need
to speak to the caller. In the future, cellular service may also compete more
directly with traditional landline telephone service providers.

        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 
Western Wireless.

        In the future, Western Wireless expects to face increased competition
from entities providing similar services using other communications
technologies, including satellite-based telecommunications systems. While some
of these technologies and services are currently operational, others are being
developed or may be developed in the future.

        CELLULAR INTELLECTUAL PROPERTY

        Cellular One is a service mark registered with the United States Patent
and Trademark Office. The service mark is owned by Cellular One Group, a
Delaware general partnership comprised of Cellular One Marketing, Inc., a
subsidiary of Southwestern Bell, together with Cellular One Development, Inc., a
subsidiary of AT&T and Vanguard Cellular Systems, Inc. Western Wireless uses the
Cellular One service mark to identify and promote its cellular telephone service
pursuant to licensing agreements with Cellular One Group. The licensing
agreements require Western Wireless to provide high-quality cellular telephone
service to its customers, and to maintain a certain minimum overall customer
satisfaction rating in surveys commissioned by Cellular One Group. The licensing
agreements that Western Wireless has entered into are for original five-year
terms expiring on various dates. Assuming compliance by Western Wireless with
the provisions of the agreements, each of these agreements may be renewed at
Western Wireless' option for three additional five-year terms.

        Western Wireless holds federal trademark registration of the mark
"Western Wireless" and has registered or applied for various other trade and
service marks with the United States Patent and Trademark Office.

        CELLULAR GOVERNMENTAL REGULATION

        The FCC regulates the licensing, construction, operation, acquisition
and sale of cellular systems in the United States pursuant to the Communications
Act of 1934 (the "Communications Act" ), as amended from time to time, and the
rules, regulations and policies promulgated by the FCC thereunder.

        LICENSING OF CELLULAR SYSTEMS

        A cellular communications system operates under a protected geographic
service area license granted by the FCC for a particular market on one of two
frequency blocks allocated for cellular service. One license for each market was
initially awarded to a company or group that was affiliated with a local
landline telephone carrier in such market and is called the wireline or "B" band
license and the other license is called the non-wireline or "A" band license.
Following notice of completion of construction, a cellular operator obtains
initial operating authority. Cellular authorizations are generally issued for a
10-year term beginning on the date of the initial notification of construction
by a cellular carrier. Under FCC rules, the authorized service area of a
cellular provider in each of its markets is referred to as the Cellular
Geographic Service Area or CGSA. A cellular licensee has the exclusive right to
serve the entire area that falls within the licensee's MSA or RSA for a period
of five years after grant of the licensee's construction permit. At the end of
the five-year period, however, the licensee's exclusive CGSA rights become
limited to the area actually served by the licensee as of that time, as
determined pursuant to a formula adopted by the FCC. After the five-year period
any entity may apply to serve portions of the MSA or RSA not being served by the
licensee. The five year exclusivity period has expired for most licensees and
parties have filed unserved area applications, including some in Western
Wireless markets.

        Near the conclusion of the 10-year license term, licensees must file
applications for renewal of licenses. The FCC has adopted specific standards to
apply to cellular renewals, under which standard the FCC will award a renewal
expectancy to a cellular 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. Violations of the
Communications Act or the FCC's rules could result in license revocations,
forfeitures or fines. Western Wireless has approximately 70 cellular licenses
which will be subject to renewal in the next three years. While Western believes
that each of its cellular licenses will be renewed, there can be no assurance
that all of the licenses will be renewed.

        Cellular radio service providers must also satisfy a variety of FCC
requirements relating to technical and reporting matters. One such requirement
is the coordination of proposed frequency usage with adjacent cellular users,
permittees and licensees in order to avoid electrical interference between
adjacent systems. In addition, the height and power of base station transmitting
facilities and the type of signals they emit must fall within specified
parameters. The FCC has also provided guidelines respecting cellular service
resale and roaming practices and the terms under which certain ancillary
services may be provided through cellular facilities.

        Under the FCC's current rules specifying spectrum ownership limits
affecting cellular licensees, no entity may hold licenses for more than 45
MHz of cellular, PCS and SMR services regulated as Commercial Mobile Radio
Service ("CMRS") 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 Geographic Service Area
(""CGSA'') and/or SMR service area, as defined by the FCC). The FCC is currently
reexamining these ownership limits.

        Western Wireless owns cellular licenses serving markets that are wholly
or partially within the Denver MTA and the Oklahoma City MTA, resulting in
Western Wireless exceeding the FCC's current 45 MHz of cellular, PCS and CMRS
cross ownership restriction described above. Western Wireless has filed waiver
requests with the FCC with respect to both MTAs, both of which are pending, and
has been allowed to delay compliance with the ownership restriction until the
FCC rules on the waiver requests. In the event that this restriction is not
waived or the rule itself revised, either VoiceStream or Western Wireless will
be obligated to divest sufficient portions of their markets in the Denver and
Oklahoma City MTA to come into compliance with the rules. Western Wireless does
not believe such restriction or any actions Western Wireless or Western Wireless
is required to take to comply therewith will have a material adverse effect on
Western Wireless due to the relatively minor geographic overlap.

        Cellular systems are subject to certain Federal Aviation Administration
("FAA") regulations respecting the location, lighting and construction of
transmitter towers and antennae 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 Western Wireless'
activities. Western Wireless uses, among other facilities, 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.



                                       10
<PAGE>   11
        The Communications Act preempts state and local regulation of the entry
of, or the rates charged by, any provider of commercial mobile radio service
("CMRS") or any private mobile radio service, which CMRS includes cellular
service.

        Western Wireless has purchased its Cellular licenses from private
parties or the federal government. Western Wireless has used a combination of
debt and equity financing to acquire such licenses.

        TRANSFERS AND ASSIGNMENTS OF CELLULAR LICENSES

        The Communications Act and FCC rules require the FCC's prior approval of
the assignment or transfer of control of a construction permit or license for a
cellular system (proforma transfer of control does not require prior FCC
approval). Subject to FCC approval, a license or permit may be transferred from
a non-wireline entity to a wireline entity, or vice versa. Non-controlling
interests in an entity that holds a cellular license or cellular system
generally may be bought or sold without prior FCC approval. Any acquisition or
sale by Western Wireless of 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 any state or local regulatory authorities having
competent jurisdiction.

        In addition, the FCC's rules prohibit the alienation of any ownership
interest in an RSA application, or an entity holding such an application, prior
to the grant of a construction permit. For unserved cellular areas, no change of
control may take place until after the FCC has granted both a construction
permit and a license and the licensee has provided service to the public for at
least one year. These restrictions affect the ability of prospective purchasers,
including Western Wireless, to enter into agreements for RSA and unserved area
acquisitions prior to the lapse of the applicable transfer restriction periods.
The restriction on sales of interests in RSA and unserved area applications and
on agreements for such sales should not have a greater effect on Western
Wireless or any other prospective buyer.

        WESTERN WIRELESS EMPLOYEES AND LABOR RELATIONS

        Western Wireless considers its labor relations to be good and, to
Western Wireless' knowledge, none of its employees is covered by a collective
bargaining agreement. As of December 31, 1998, Western Wireless, excluding
VoiceStream, employed a total of approximately 2,137 people in the following
areas:

THE BUSINESS OF WESTERN WIRELESS INTERNATIONAL

        After the Spin-off, Western Wireless International ("WWI") will continue
to operate as a subsidiary of Western Wireless.

        GENERAL OVERVIEW

        WWI has pursued a strategy of obtaining interests in licenses to 
provide telecommunications services in a variety of countries. The elements of 
WWI's strategy are to find opportunities where, with local partners, the 
company can leverage its operating knowledge and construction capabilities to 
bring wireless telecommunications to markets it believes are underserved by the 
existing, if any, wireless operators. In addition, it has been the strategy of 
WWI to pursue ventures that it believes will result in a minimal amount of 
license costs to be paid to the licensing authority.

        Operating companies in which WWI has a minority interest have begun 
operations in the Republics of Latvia and Georgia and Iceland and had a total 
of 75,000 subscribers as of December 31, 1998.

        In addition, WWI has minority interests in licenses in Ghana, Haiti and 
Croatia. WWI expects the operating companies to begin to provide wireless 
services in each of these countries during 1999.

        A joint venture which WWI controls has been notified by the Irish 
Government that it is the preferred applicant for a DCS-1800/GSM 900 mobile 
communication license in Ireland. The license has not yet been issued, as the 
decision by the Irish Government is subject to a pending legal proceeding.

THE PCS BUSINESS OF VOICESTREAM

        After the Spin-off, Western Wireless and VoiceStream will operate as
separate businesses. VoiceStream will continue to operate its PCS business in
urban areas in the United States.

        GENERAL

        VoiceStream provides PCS services under the VoiceStream brand name in 11
urban markets -- Denver, Seattle/Tacoma, Phoenix/Tucson, Portland, Salt Lake
City, Des Moines, Oklahoma City, Honolulu, El Paso, Albuquerque and Boise -- and
is currently constructing systems in San Antonio and Austin. VoiceStream holds
107 broadband PCS licenses covering approximately 62.6 million persons.
VoiceStream has experienced rapid growth of its operations since commencement in
February 1996. VoiceStream's subscribers have grown to 322,400 at December 31,
1998, and revenues have grown to $168.0 million for the year ended December 31,
1998. VoiceStream believes these results reflect the strong demand for wireless
services in its markets, the success of its marketing strategy and its
management capabilities.

        VoiceStream believes its PCS service offerings are more extensive than
those generally offered by cellular systems in VoiceStream's markets. Service
offerings include all of the services typically provided by cellular systems, as
well as paging, caller identification, text messaging, smart cards, voice mail,
over-the-air activation and over-the-air subscriber profile management.

        VoiceStream's goal is to achieve significant market penetration by
aggressively marketing competitively priced services under its proprietary
VoiceStream brand name, offering enhanced services not generally provided by
cellular operators and providing superior customer service. In addition,
VoiceStream is well-positioned to be a low-cost provider of PCS services by
utilizing centralized management, marketing, billing and customer service
functions, and by focusing on efficient customer acquisition and retention.

        VoiceStream selected GSM as the digital standard for its PCS systems
because it believes GSM has significant advantages over the other competing
digital standards. These advantages include the widest array of features, and an
open system architecture that provides cost advantages in choosing from a
variety of equipment options and providers, which result from the experience of
years of proven operability in Europe and Asia. GSM is the leading digital
wireless standard in the world, with over 120 million customers in 130
countries.

        VoiceStream has entered into roaming agreements with substantially all
of the licensees that have deployed the GSM standard in North America. Such
agreements will allow VoiceStream's subscribers to roam in these carriers' PCS
markets, and vice versa, when such systems are operational. VoiceStream also has
approximately 90 reciprocal roaming agreements with a variety of international
carriers who have chosen to deploy the GSM standard. In addition, VoiceStream
has entered into roaming agreements with several cellular carriers, including
Western Wireless.

        VOICESTREAM STRATEGY

        VoiceStream's principal focus is on the operation of PCS systems in
urban markets in the United States. VoiceStream believes that PCS is the optimum
technology for more densely populated urban areas where cellular systems are
generally more expensive to deploy and face potential capacity constraints.

        VoiceStream's operating strategy is to: (i) construct and operate high
quality systems with extensive coverage in urban areas; (ii) expand operations
through increased subscriber growth and usage; (iii) utilize centralized
management, back office functions and its own sales force to improve operating
efficiencies and generate greater economies of scale; and (iv) acquire
additional PCS licenses in urban markets.

        VoiceStream is implementing its strategy by: (i) expanding its present
systems and building new systems; (ii) offering a targeted range of products to
complement today's business and personal lifestyles at competitive prices; (iii)
continually upgrading the quality of its network; (iv) establishing brand
recognition through a strong sales and marketing program; and (v) providing a
superior level of customer service.

        VOICESTREAM FORMATION

        VoiceStream was formed in 1994 as "Western PCS Corporation" to
participate on behalf of Western Wireless and its shareholders in FCC auctions
of various PCS licenses. It was a wholly owned subsidiary of Western Wireless
until February 1998, when Hutchison Telecommunications PCS (USA) Limited
("Hutchison USA"), a subsidiary of Hutchison Whampoa Limited ("Hutchison"),
invested $248.4 million (the "Hutchison Investment") to purchase newly issued
shares of common stock representing a 19.9 percent interest in VoiceStream.

        VOICESTREAM MARKETS AND SYSTEMS

        VoiceStream owns 107 broadband PCS licenses, seven of which are for
Major Trading Area ("MTA") license areas and 100 of which are for Basic Trading
Area ("BTA") license areas, covering a total of approximately 62.6 million
persons. See "-- PCS Governmental Regulation, Licensing of PCS Systems." MTAs
and BTAs are based on the Rand McNally 1992 Commercial Atlas & Marketing Guide,
123rd Edition, at pages 38-39 ("BTA/MTA Map"). Rand McNally organizes the 50
States and the District of Columbia into 47 MTAs and 487 BTAs. The BTA/MTA Map
is available for public inspection at the Office of Engineering and Technology's
Information Center, 2000 M Street, NW., Washington, DC 20554.

        VoiceStream obtained its licenses as follows: (i) six MTA licenses in
the FCC's A Block auction in 1995; (ii) one MTA license from another carrier in
1996; (iii) 92 BTA licenses in the FCC's D and E Block auctions in 1997; and
(iv) eight BTA licenses from another carrier in October 1997. Cook Inlet Western
Wireless PV/SS PCS, LP ("Cook Inlet PCS"), in which VoiceStream owns a 49.9%
limited partnership interest, owns 18 PCS BTA licenses that were acquired in the
FCC's C and F Block auctions. Cook Inlet PCS provides service in the Spokane,
Tulsa, Phoenix/Tucson and Seattle/Tacoma markets. VoiceStream has also formed
another joint venture with some of the same Cook Inlet PCS partners to
participate in the FCC's reauction of C and F Block licenses. Through other
joint ventures in which VoiceStream has an interest, PCS service is available in
the Wichita market and certain markets in Iowa, and is anticipated to be
available in certain markets in southern Texas in 1999. All of these operational
markets use the internationally-proven GSM technology.

   
        See the summarized financial results of VoiceStream's PCS operations in
the footnotes to the consolidated financial statements located in Part II of
this Form 10-K.
    

        Population data in the following table is estimated for 1999 based upon
1998 estimates by Equifax adjusted by VoiceStream by applying Equifax's growth
factors from 1997 to 1998.

        COOK INLET/VOICESTREAM PCS LLC

        On February 12, 1999, VoiceStream formed a Delaware limited liability
company, Cook Inlet/ VoiceStream PCS LLC. This LLC, like Cook Inlet PCS, is
ultimately controlled by Cook Inlet Region, Inc., and is participating in FCC
reauctions of C Block and F Block licenses. 

        VOICESTREAM PRODUCTS AND SERVICES

        VoiceStream provides a variety of wireless products and services
designed to match a range of needs for business and personal use. VoiceStream
currently offers several distinct services and features in its PCS systems,
including:

o   Enhanced Features -- VoiceStream's systems offer caller identification, call
    hold, voice mail and numeric paging, as well as custom calling features such
    as call waiting, conference calling and call forwarding.

o   Messaging and Wireless Data Transmission -- Digital networks offer voice and
    data communications, including text messaging, through a single handset.
    VoiceStream believes that, as data transmission services develop, a number
    of uses for such services will emerge.

o   Call Security and Privacy -- Sophisticated encryption algorithms provide
    increased call security, encouraging users to make private, business and
    personal calls with significantly lower risk of eavesdropping than on
    analog-based systems.


                                       18
<PAGE>   19

o   Smart Card -- "Smart" cards, programmed with the user's billing information
    and a specified service package, allow subscribers to obtain PCS
    connectivity automatically, simply by inserting their smart cards into
    compatible PCS handsets.

o   Over-the-Air Activation and Over-the Air Subscriber Profile Management --
    VoiceStream is able to transmit changes in the subscriber's feature package,
    including mobile number assignment and personal directory numbers, directly
    to the subscriber's handset.

o   Roaming -- Subscribers are able to roam throughout the United States, either
    on other GSM-based PCS systems operated by current licensees or by using
    dual-mode handsets that can be used on existing cellular systems.
    VoiceStream has entered into roaming agreements which allow its customers to
    roam on cellular systems. Dual-mode handsets allow roaming onto analog
    cellular systems.

        VOICESTREAM MARKETING, SALES AND CUSTOMER SERVICE

        VoiceStream's sales and marketing strategy is to generate continued
subscriber growth and increased subscriber revenues. In addition, VoiceStream
targets a customer base which it believes is likely to generate higher monthly
service revenues, while attempting to achieve a low cost of adding new
subscribers. VoiceStream markets its services under a proprietary brand name,
and sells its products and services through a combination of direct and indirect
distribution channels.

        Marketing -- VoiceStream markets its PCS products and services under the
proprietary VoiceStream brand name. VoiceStream's objective is to develop brand
recognition of VoiceStream through substantial advertising and direct marketing
in each of its PCS markets. In marketing its PCS services, VoiceStream
emphasizes the enhanced features, privacy and competitive pricing of such
services. VoiceStream concentrates its marketing efforts primarily on businesses
and individuals "on-the-go," who benefit from integrated mobile voice, messaging
and wireless data transmission capabilities, and enhanced features and services.

        Sales -- VoiceStream sells its products and services through a
combination of direct and indirect channels. VoiceStream operates 90
company-owned retail sales locations and utilizes a direct sales force of over
680 persons. VoiceStream's training programs provide its sales employees with an
in-depth understanding of VoiceStream's system, products and services so that
they, in turn, can provide extensive information to prospective customers. Sales
commissions generally are linked both to subscriber revenue and subscriber
retention, as well as to activation levels.

        VoiceStream believes that its local sales offices provide the physical
presence in local markets necessary to position VoiceStream as a quality local
service provider, and give VoiceStream greater control over both its costs and
the sales process. VoiceStream also utilizes indirect sales through an extensive
network of national and local merchant and specialty retailers. VoiceStream
intends to continue to use a combination of direct and indirect sales channels,
with the mix depending on the retail needs of each particular market.

        In addition, VoiceStream acts as a retail distributor of handsets and
maintains inventories of handsets. Although subscribers generally are
responsible for purchasing or otherwise obtaining their own handsets,
VoiceStream has historically sold handsets below cost to respond to competition
and general industry practice and expects to continue to do so in the future.

        Customer Service -- Customer service is a significant element of
VoiceStream's operating philosophy. VoiceStream is committed to attracting and
retaining subscribers by providing consistently superior customer service. In
Albuquerque, New Mexico, VoiceStream maintains a highly sophisticated monitoring
and control system, a staff of customer service personnel and a well-trained
technical staff to handle both routine and complex questions as they arise, 24
hours a day, 365 days a year.

        VoiceStream implements credit check procedures at the time of sale and
continuously monitors customer churn (the rate of subscriber attrition).
VoiceStream believes that it helps manage its churn rate through an outreach
program implemented through its sales force and customer service personnel. This
program not only enhances subscriber loyalty, but also increases add-on sales
and customer referrals. The outreach program allows the sales staff to check
customer satisfaction, as well as to offer additional calling features, such as

        VOICESTREAM SUPPLIERS AND EQUIPMENT VENDORS

        VoiceStream does not manufacture any of the handsets or network
equipment used in its operations. The high degree of compatibility among
different manufacturers' models of handsets and network equipment allows
VoiceStream to design, construct and operate its systems without being dependent
upon any single source of such equipment. The handsets and network equipment
used in VoiceStream's operations are available for purchase from multiple
sources, and VoiceStream anticipates that such equipment will continue to be
available in the foreseeable future. VoiceStream currently purchases handsets
primarily from Motorola Inc., Ericsson Inc., Mitsubishi Wireless Communications,
Inc. and Nokia Mobile Phones, Inc. (together with its affiliate, Nokia).
VoiceStream currently purchases network equipment primarily from Northern
Telecom Inc. and Nokia.

        VOICESTREAM COMPETITION

        Competition for subscribers among wireless licensees is based
principally upon the services and features offered, the technical quality of the
wireless systems, customer service, system coverage, capacity and price. Under
current FCC rules, there may be up to seven PCS licensees in each geographic
area in addition to the two cellular licensees. Also, SMR dispatch system
operators have constructed digital mobile communications systems on existing SMR
frequencies, referred to as ESMR, in many cities throughout the United States,
including some of the markets in which VoiceStream operates.

        VoiceStream is a relatively new entrant in a highly competitive market.
VoiceStream's principal competitors are the cellular service providers in its
markets, many of which have been operational for a number of years, and national
PCS providers, many of which offer no or low cost roaming and toll calls. Many
of VoiceStream's competitors have significantly greater financial and technical
resources than those available to VoiceStream and provide comparable services in
competition with VoiceStream's PCS systems. These competitors include AirTouch,
AT&T Wireless, Bell Atlantic Moble, Inc., GTE Mobilnet Inc., Sprint PCS and US
West. VoiceStream also competes with paging, dispatch and conventional mobile
telephone companies, resellers and landline telephone service providers in its
PCS markets. Potential users of wireless systems may, however, find their
communications needs satisfied by other current and developing technologies. One
or two-way paging or beeper services that feature voice messaging and data
display as well as tone only service may be adequate for potential subscribers
who do not need to speak to the caller. In the future, wireless service may also
compete more directly with traditional landline telephone service providers.

        VoiceStream's principal PCS competitors use standards other than GSM. As
a result, VoiceStream's subscribers may not be able to conveniently use PCS
services while roaming in areas outside its markets. US West and Sprint PCS use
the CDMA standard, AT&T Wireless and Southwestern Bell use the TDMA standard.

        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. 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 VoiceStream. 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.

        In the future, VoiceStream expects to face increased competition from
entities providing similar services using other communications technologies.
While some of these technologies and services are currently operational, others
are being developed or may be developed in the future.

        VoiceStream recognizes that technological advances and changing
regulations have led to rapid evolution of the wireless telecommunications
industry. At the end of 1996, the FCC transferred 200 MHz of spectrum previously
allocated to federal government use to the private sector. In April of 1997, the
FCC auctioned 30 MHz of spectrum for Wireless Communications Services, which can
provide fixed or mobile telecommunications service. In late 1997, the FCC also
auctioned 10 MHz of spectrum for SMR service, another potential competitor with
PCS and cellular service. Moreover, in 1998, the FCC auctioned more than 1000
MHz of spectrum for Local Multipoint Distribution Service ("LMDS"). VoiceStream
acquired 16 licenses as a result of such auction. During 1998, the FCC auctioned
25 MHz of spectrum for the General Wireless Communications Service, plus
additional spectrum in the 220 MHz and 39 MHz bands. VoiceStream cannot foresee
how technological progress or economic incentive will affect competition from
these new services. In all instances, the FCC reserves the right to amend or
repeal its service regulations and auction schedule.

        VOICESTREAM INTELLECTUAL PROPERTY

        VoiceStream holds federal trademark registration of the marks
"VoiceStream" and "VoiceStream and Design," and has registered or applied for
various other trade and service marks with the United States Patent and
Trademark Office.

        VOICESTREAM ORGANIZATION

        VoiceStream holds its FCC licenses and conducts all operations through a
number of direct and indirect wholly-owned subsidiaries and through certain
affiliates. Indirect wholly-owned subsidiaries of VoiceStream are the 49.9%
limited partner of Cook Inlet PCS, the 38.0% limited partner of Iowa Wireless,
the 18.0% member of STPCS, and the non-controlling member of Cook
Inlet/VoiceStream LLC. In three BTAs, VoiceStream and Cook Inlet PCS each own a
license for 10 MHz of PCS spectrum that are the subject of agreements allowing
each of VoiceStream and Cook Inlet PCS to operate on the PCS systems built by
VoiceStream in those BTAs.

        PCS GOVERNMENTAL REGULATION

        The FCC regulates the licensing, construction, operation, acquisition
and sale of PCS systems in the United States pursuant to the Communications Act
of 1934, as amended from time to time, and the rules, regulations and policies
promulgated by the FCC thereunder.

        LICENSING OF PCS SYSTEMS

        In order to increase competition in wireless communications, promote
improved quality and service and make available the widest possible range of
wireless services, federal legislation was enacted directing the FCC to allocate
radio frequency spectrum for PCS by competitive bidding. A 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. The FCC has divided the United States and its possessions and
territories into PCS markets made up of 493 BTAs and 51 MTAs. Each MTA consists
of at least two BTAs. As many as seven licensees will compete in each PCS
service area. The FCC has allocated 120 MHz of radio spectrum in the 2 GHz band
for licensed PCS services. The FCC divided the 120 MHz of spectrum into six
individual blocks, each of which is allocated to serve either MTAs or BTAs. The
spectrum allocation includes two 30 MHz blocks (A and B Blocks) licensed for
each of the 51 MTAs, one 30 MHz block (C Block) (which has been split in some
BTAs into two 15 MHz blocks) licensed for each of the 493 BTAs, and three 10 MHz
blocks (D, E and F Blocks) licensed for each of the 493 BTAs. A PCS license will
be awarded for each MTA or BTA in every block, for a total of more than 2,000
licenses. During 1997, the last of these auctions was completed; however, a
reauction of certain C, D, E and F Block licenses is currently scheduled for
1999.

        Under the FCC's current rules specifying spectrum ownership limits
affecting broadband PCS licensees, no entity may hold licenses for more than 45
MHz of PCS, cellular and SMR services regulated as Commercial Mobile Radio
Service ("CMRS") 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 CGSA and/or SMR service area, as
defined by the FCC). The FCC is currently reexamining these ownership limits.

        Western Wireless owns cellular licenses serving markets that are wholly
or partially within the Denver MTA and the Oklahoma City MTA, resulting in
Western Wireless exceeding the FCC's current 45 MHz CMRS cross ownership
restriction described above. Western Wireless has filed waiver requests with the
FCC with respect to both MTAs, both of which are pending, and has been allowed
to delay compliance with the ownership restriction until the FCC rules on the
waiver requests. In the event that this restriction is not waived or the rule
itself revised, either VoiceStream or Western Wireless will be obligated to
divest sufficient portions of their markets in the Denver and Oklahoma City MTA
to come into compliance with the rules. VoiceStream does not believe such
restriction or any actions Western Wireless or VoiceStream is required to take
to comply therewith will have a material adverse effect on VoiceStream due to 
the relatively minor geographic overlap.

        All PCS licenses are granted for a ten year term, at the end of which
they must be renewed. The FCC has adopted specific standards to apply to PCS
renewals, under which 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 30 MHz PCS licensees, including VoiceStream, must
construct facilities that offer coverage to one-third of the population of their
service area within five 


                                       21
<PAGE>   22

years of their initial license grants 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.

        FCC rules restrict the voluntary assignments or transfers of control of
C and F Block licenses. During the first five years of the license term,
assignments or transfers affecting control are permitted only to assignees or
transferees that meet the eligibility criteria for participation in the
entrepreneur block auction at the time the application for assignment or
transfer of control is filed, or if the proposed assignee or transferee holds
other licenses for C and F Blocks and, at the time of receipt of such licenses,
met the same eligibility criteria. Any transfers or assignments during the
entire ten year initial license term are subject to an unjust enrichment penalty
of acceleration of any installment payment plans should the assignee or
transferee not qualify for the same benefits. Any transfers or assignments
during the first five years of the initial license term are subject to an unjust
enrichment penalty of forfeiture of bidding credits. In the case of the C and F
Blocks, the FCC will conduct random audits to ensure that licensees are in
compliance with the FCC's eligibility rules. Violations of the Communications
Act or the FCC's rules could result in license revocations, forfeitures or
fines.

        For a period of up to ten years after the grant of a PCS license
(subject to extension), a PCS licensee will share spectrum with existing
licensees that operate certain fixed microwave systems within its license area.
To secure a sufficient amount of unencumbered spectrum to operate its PCS
systems efficiently and with adequate population coverage, VoiceStream 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 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. The FCC has shortened the voluntary negotiation period by one year
(without lengthening the mandatory negotiation period) for PCS licensees in the
C, D, E and F Blocks. 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. 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 respecting the
location, lighting and construction of transmitter towers and antennae 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 VoiceStream's activities. VoiceStream uses, among
other facilities, 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.

        VoiceStream has purchased its PCS licenses from private parties and the
federal government. VoiceStream has used a combination of debt and equity
financing to acquire such licenses. Some joint ventures in which VoiceStream is
a member have utilized financing from the federal government to the extent
available.

        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 system (proforma
transfer of control does not require prior FCC approval). 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 PCS license or PCS
system generally may be bought or sold without FCC approval. Any acquisition or
sale by VoiceStream of PCS 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.

        VOICESTREAM EMPLOYEES AND LABOR RELATIONS

        VoiceStream considers its labor relations to be good and, to
VoiceStream's knowledge, none of its employees is covered by a collective
bargaining agreement. As of December 31, 1998, VoiceStream employed a total of
approximately 1,834 people in the following areas:

        VOICESTREAM FOREIGN OWNERSHIP

        Under the Communications Act, no more than 25% of an FCC licensee's
capital stock may be indirectly owned or voted by non-U.S. citizens or their
representatives, by a foreign government, or by a foreign corporation, absent an
FCC finding that a higher level of alien ownership is not inconsistent with the
public interest. In November 1997, the FCC adopted new rules, effective in
February 1998, in anticipation of implementation of the World Trade Organization
Basic Telecom Agreement ("WTO Agreement"). Formerly, potential licensees had to
demonstrate that their markets offered effective competitive opportunities in
order to obtain authorization to exceed the 25% indirect foreign ownership
threshold. Under the new rules, this showing now only applies to non-WTO
members. Applicants from WTO Agreement signatories have an "open entry"
standard: they are presumed to offer effective competitive opportunities.
However, the FCC reserves the right to attach additional conditions to a grant
of authority, and, in the exceptional case in which an application poses a very
high risk to competition, to deny the application. The limitation on direct
foreign ownership in an FCC licensee remains fixed at 20%, with no opportunity
to increase the percentage, and is unaffected by the FCC's new rules.
VoiceStream has applied for and received FCC approval for foreign ownership of
up to 39.9%. As of the December 31, 1998, foreign ownership of VoiceStream is
less than 30%.

        The WTO Agreement also obligates signatories to open their domestic
telecommunications markets to foreign investment and foreign corporations. The
WTO Agreement will increase investment and competition in the United States,
potentially leading to lower prices, enhanced innovation and better service. At
the same time, market access commitments from WTO Agreement signatories will
provide U.S. service suppliers opportunities to expand abroad.

TELECOMMUNICATIONS ACT OF 1996 AND OTHER RECENT INDUSTRY DEVELOPMENTS

        On February 8, 1996, the Telecommunications Act of 1996 (the
"Telecommunications Act") was signed into law, substantially revising the
regulation of communications. The goal of the Telecommunications Act is to
enhance competition and remove barriers to market entry, while deregulating the
communications industry to the greatest extent possible. To this end, local and
long-distance communications providers will, for the first time, be able to
compete in the other's market, and telephone and cable companies will likewise
be able to compete in each other's markets. To facilitate the entry of new
carriers into existing markets, the Telecommunications Act imposes certain
interconnection requirements on incumbent carriers. Additionally, all
telecommunications providers are required to make an equitable and
nondiscriminatory contribution to the preservation and advancement of universal
service. VoiceStream cannot predict the outcome of the FCC's rulemaking
proceedings to promulgate regulations to implement the new law or the effect of
the new regulations on cellular service or PCS, and there can be no assurance
that such regulations will not adversely affect VoiceStream's business or
financial condition.

        The Telecommunications Act codifies the policy that non-regional Bell
operating company CMRS providers will not be required to provide equal access to
long distance carriers, and relieved such CMRS providers of their existing equal
access obligations. The FCC, however, may require CMRS carriers to offer
unblocked access (i.e., implemented by the subscriber's use of a carrier
identification code or other mechanisms at the time of placing a call) to the
long distance provider of a subscriber's choice. The FCC has terminated its
inquiry into the imposition of equal access requirements on CMRS providers.


                                       23
<PAGE>   24
        On July 26, 1996, the FCC released a Report and Order establishing
timetables 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. Cellular
and PCS providers must be able to process and transmit 911 calls (without call
validation), including those from callers with speech or hearing disabilities.
If a cost recovery mechanism is in place and a Public Service Answering Point
("PSAP") requests and is capable of processing the caller's telephone number and
location information, cellular, PCS, and other mobile service provider must
relay a caller's automatic number identification and Cell Site location, and by
2001 they must be able to identify the location of a 911 caller within 125
meters in 67% of all cases. State actions incompatible with the FCC rules are
subject to preemption. On December 1, 1997, the FCC required wireless carriers
to transmit all 911 calls without regard to validation procedures intended to
identify and intercept calls from non-subscribers.

        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
how such fixed services 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 subject to petitions for reconsideration and judicial
review (as described below), and its precise impact is difficult to predict with
certainty. However, the FCC's order concludes that CMRS providers are entitled
to reciprocal compensation arrangements with local exchange carriers ("LECs")
and prohibits LECs from charging CMRS providers for terminating LEC-originated
traffic. Under the rules adopted by the FCC, states must set arbitrated rates
for interconnection and access to unbundled elements based upon the LECs'
long-run incremental costs, plus a reasonable share of forward-looking joint and
common costs. In lieu of such cost-based rates, the FCC has established proxy
rates to be used by states to set interim interconnection rates pending the
establishment of cost-based rates. The FCC has also permitted states to impose
"bill and keep" arrangements, under which CMRS providers would make no payments
for LEC termination of calls where LECs and CMRS providers have symmetrical
termination costs and roughly balanced traffic flows. However, the FCC has found
no evidence that these conditions presently exist. The relationship of these
charges to the payment of access charges and universal service contributions has
not yet been resolved by the FCC. LECs and state regulators filed appeals of the
interconnection order, which have been consolidated in the US Court of Appeals
for the Eighth Circuit. The Court has vacated many of the rules adopted by the
FCC, including those rules governing the pricing of interconnection services,
but specifically affirmed the FCC rules governing interconnection with CMRS
providers. In January 1998, the U.S. Supreme Court agreed to review the Eighth
Circuit decision. In January 1999, the U.S. Supreme Court reversed many aspects
of the Eighth Circuit's judgment, holding that: (i) the FCC has general
jurisdiction to implement the 1996 Act's local-competition provisions; (ii) the
FCC's rules governing unbundled access are consistent with the 1996 Act, except
for Rule 319, which gives requesting carriers blanket access to network
elements; and (iii) the "pick and choose" rule is a reasonable interpretation of
the 1996 Act. The FCC will now have to reexamine the list of unbundled network
elements that incumbent local exchange carriers must offer to competitors.
Furthermore, as a result of the Supreme Court's vacating and remanding the
Eighth Circuit's ruling that the FCC lacked authority to set local pricing
standards, the Eighth Circuit will have to decide whether the FCC's
total-element long-run incremental cost methodology for setting interconnection
and unbundled network element rates violates the 1996 Act.

        In its implementation of the Telecommunications Act, the FCC recently
established new federal universal service rules, under which wireless service
providers for the first time are eligible to receive universal service
subsidies, but also are required to contribute to both federal and state
universal service funds. For the first quarter of 1998, the FCC's universal
service assessments amount to 0.72% of interstate and intrastate
telecommunications revenues for schools, libraries and rural healthcare support
mechanisms and an additional 3.19% of interstate telecommunications revenues for
high cost and low income support mechanisms. Various parties have challenged the
FCC's universal service rules, and the cases have been consolidated in the U.S.
Court of Appeals for the Fifth Circuit. VoiceStream cannot predict the outcome
of this proceeding.

        The FCC has adopted rules on telephone number portability which will
enable subscribers to migrate their landline and cellular telephone numbers to a
PCS carrier and from a PCS carrier to another service provider. Various parties
have challenged the number portability requirements as they apply to CMRS
providers. These challenges are still pending at the FCC and in the courts.
VoiceStream can not predict the outcome of such challenges. In February 1999,
the FCC extended the deadline for CMRS carriers to implement service provider
local number portability until November 24, 2002.

                                       24
<PAGE>   25
        The 1996 Act applied the FCC's long-standing rate integration policy to
all providers of interstate, interexchange services, including CMRS. Generally,
rate integration requires interstate telecommunications companies to provide
interstate long distance services to their customers in each state, including
U.S. territories, at rates no higher than those they charge to their customers
in other states. The FCC is in the process of determining how best to encourage
CMRS providers to move forward with innovative pricing plans in light of the
rate integration mandate of the 1996 Act. The matter is currently the subject of
an appeal before the United States Court of Appeals for the District of Columbia
Circuit.

        The Compliance with Communications Assistance for Law Enforcement Act
("CALEA"), enacted by Congress on October 25, 1994, requires telecommunications
carriers to ensure that their facilities are technically capable of assisting
law enforcement officials to use wiretaps and like devices to intercept and/or
isolate subscriber communications. The compliance deadline has been extended
until June 30, 2000. Compliance with CALEA requirements could result in
substantial costs for CMRS carriers, including Western Wireless and VoiceStream.

</TABLE>

    

(1) The number of shares outstanding has been calculated based on the
    requirements of Statement of Financial Accounting Standards No. 128. Due to 
    the net loss incurred during the periods presented, all options outstanding 
    are anti-dilutive. Thus basic and diluted loss per share are equal.

(2) EBITDA represents operating income (loss) before depreciation and
    amortization. Management believes EBITDA provides meaningful additional
    information on Western Wireless' operating results and on its ability to
    service its long-term debt and other fixed obligations and to fund Western
    Wireless' continuing growth. EBITDA is considered by many financial analysts
    to be a meaningful indicator of an entity's ability to meet its future
    financial obligations, and growth in EBITDA is considered to be an indicator
    of future profitability, especially in a capital-intensive industry such as
    wireless telecommunications. EBITDA should not be construed as an
    alternative to operating income (loss) as determined in accordance with
    United States generally accepted accounting principles (GAAP), as an
    alternate to cash flows from operating activities (as determined in
    accordance with GAAP), or as a measure of liquidity. Because EBITDA is not
    calculated in the same manner by all companies, Western Wireless'
    presentation may not be comparable to other similarly titled measures of
    other companies. In 1994, Western Wireless recorded provisions for
    restructuring costs of $2.5 million. EBITDA before such provisions for
    restructuring costs would have been $4.6 million.

CONSOLIDATED OVERVIEW

        Western Wireless provides wireless communications services in the United
States principally through the ownership and operation of cellular and PCS
systems. The cellular operations are primarily in rural areas and the PCS
operations are primarily in urban areas due to Western Wireless' belief that
there are certain strategic advantages to operating each technology in these
respective areas. Western Wireless provides PCS services through its 80.1%
ownership of VoiceStream Wireless.

        On February 8, 1999, Western Wireless announced its intention to
separate VoiceStream from Western Wireless' other operations (the "Spin-off").
Western Wireless has received a favorable ruling by the Internal Revenue Service
for a tax free spin-off, and the approval by its board of directors to take the
necessary steps to complete the Spin-off. Western Wireless will distribute all
of its interest in VoiceStream to its shareholders upon the Spin-off. Although
VoiceStream has been operated separately from Western Wireless' other operations
and has been a separate legal entity since its inception, the Spin-off will
establish VoiceStream as a stand-alone entity with objectives separate from
those of Western Wireless. The Spin-off is subject to numerous conditions
including, among others, the receipt of certain government and third party
approvals. There is no assurance that such conditions will be met to complete
the Spin-off.

        Revenues consist primarily of subscriber revenues (including access
charges and usage charges), and equipment sales. The majority of revenues are
derived from subscriber revenues. Western Wireless expects to continue to sell
handsets below cost and regards these losses as a cost of building its
subscriber base. As used herein, "service revenues" include subscriber, roamer
and other revenue. Other revenues consist primarily of paging revenues.

        Cost of service consists of the cost of providing wireless service to
subscribers, primarily costs to access local exchange and long distance carrier
facilities and to maintain the wireless network. General and administrative
expenses include the costs associated with billing a subscriber and the
administrative costs associated with maintaining subscribers, including customer
service, accounting and other centralized functions. General and administrative
expenses also include provisions for unbillable fraudulent roaming charges and
subscriber bad debt. Sales and marketing costs include costs associated with
acquiring a subscriber, including direct and indirect sales commissions,
salaries, all costs of retail locations, advertising and promotional expenses.
Sales and marketing costs do not include the revenue or costs of handset sales.
However, when sales and marketing costs per net subscriber addition are
discussed, the revenue and costs from handset sales are included, because such
measure is commonly used in the wireless industry. Depreciation and amortization
primarily includes depreciation expense associated with the property and
equipment in service and amortization associated with its wireless licenses for
operational markets.

        Certain centralized general and administrative costs, including customer
service, accounting and other centralized functions, benefit all of Western
Wireless' operations including VoiceStream. These costs are allocated to those
operations in a manner which reflects management's judgment as to the nature of
the activity causing those costs to be incurred.

   
        EBITDA represents operating income (loss) before depreciation and
amortization. Management believes EBITDA provides meaningful additional
information on Western Wireless' operating results and on its ability to service
its long-term debt and other fixed obligations and to fund Western Wireless'
continuing growth. EBITDA is considered by many financial analysts to be a
meaningful indicator of an entity's ability to meet its future financial
obligations, and growth in EBITDA is considered to be an indicator of future
profitability, especially in a capital-intensive industry such as wireless
telecommunications. EBITDA should not be construed as an alternative to
operating income (loss) as determined in accordance with United States GAAP, as
an alternate to cash flows from operating activities (as determined in
accordance with GAAP), or as a measure of liquidity. Because EBITDA is not
calculated in the same manner by all companies, Western Wireless' presentation
may not be comparable to other similarly titled measures of other companies.
    

        In the comparisons that follow, Western Wireless has separately set
forth certain information relating to its cellular operations (including paging)
and VoiceStream's PCS operations.

WESTERN WIRELESS CELLULAR OVERVIEW

        Western Wireless provides cellular communications services in 17 western
states under the cellular one brand name. Western Wireless owns FCC licenses to
provide such services in 16 MSAs and 76 RSAs, including 12 RSAs acquired from
Triad Cellular Corporation, Triad Cellular L.P. and certain of their affiliates
(collectively "Triad") in October 1997. This purchase included RSAs in Texas,
Utah, Oklahoma and Minnesota.

        Western Wireless also holds interests in entities which own and operate
wireless licenses in certain foreign countries, including Georgia, Ghana,
Iceland and Latvia. In addition, Western Wireless has interests in entities
which have been awarded wireless licenses in Ireland, Croatia and Haiti. Western
Wireless does not own a controlling interest in any of the joint ventures
currently providing wireless services, therefore they are accounted for using
the equity method and are not included in the following discussions.

        RESULTS OF CELLULAR OPERATIONS FOR THE YEARS ENDED DECEMBER 31, 1998,
        1997, AND 1996

        Western Wireless had 660,400 cellular subscribers at December 31, 1998,
a 27.0% increase during 1998. Western Wireless had 520,000 cellular subscribers
at December 31, 1997, a 60.4% increase in 1997. Western Wireless had 324,200
cellular subscribers at December 31, 1996, a 54.7% increase during 1996. The net
number of subscribers added through system acquisitions was approximately 5,100
in 1998, 58,500 in 1997 and 4,900 in 1996. Removing the effect of the Triad
subscribers acquired in October 1997, the subscriber growth would have been
42.4% during 1997.

        The following table sets forth certain financial data as it relates to
Western Wireless' cellular operations:

</TABLE>
    

        CELLULAR REVENUES

        The increase in subscriber revenues each year is primarily due to the
growth in the number of subscribers offset slightly by a decrease in the average
monthly subscriber revenue per subscriber ("ARPU"). ARPU was $46.59 in 1998, an
8.9% decline from $51.13 in 1997, which was a 7.0% decline from $54.96 in 1996.
Over the past few years the cellular industry as a whole has also shown a
decline in the average monthly cellular subscriber revenue per subscriber.
Removing the effect of the Triad subscribers acquired in October 1997, the
average monthly cellular subscriber revenue per subscriber was $51.38 in 1997.

        The increase in roamer revenues over the past three years was caused by
an increase in roaming traffic and partially offset by decreases in the rates
charged between carriers. While Western Wireless expects total roamer minutes to
continue to increase, the decline in the rates charged between carriers may
limit the growth of roamer revenues. Excluding the effect of the Triad
acquisition, roaming revenue would have increased 35.2% in 1998 and 10.2% in
1997.


                                       31
<PAGE>   32

        Cellular equipment sales, which consists primarily of handset sales,
increased each year due to the growth in subscriber additions which resulted in
an increase in handsets sold. Offsetting this increase is a decrease in the
average handset selling price, which is the result of lower handset costs and
the competitive environment.

        CELLULAR OPERATING EXPENSES

        The increase in cost of service each year is primarily attributable to
the increased number of subscribers and the related increase in activity on the
wireless system. While cost of service increased in total dollars, it decreased
as a percentage of service revenues to 13.8% in 1998 from 16.2% in 1997 and
19.3% in 1996 due primarily to efficiencies gained from the growing subscriber
base. While Western Wireless expects cost of service dollars to continue to
increase in 1999 as a result of the growth in subscribers, Western Wireless
expects the cost of service as a percentage of service revenues to continue to
decline as greater economies of scale are realized.

        The increases in general and administrative costs each year are
primarily attributable to the increase in costs associated with supporting the
increased subscriber base. However, the general and administrative cost per
average subscriber continues to decrease as a result of efficiencies gained from
the growing subscriber base. The general and administrative cost per average
subscriber decreased to $12.55 in 1998 from $12.60 in 1997 and $14.58 in 1996.
Western Wireless expects general and administrative dollars to continue to
increase in 1999 as a result of the growth in subscribers, as well as increased
costs associated with the construction of a new call center. Initially, the
construction of the new call center may increase costs on a per subscriber
basis.

        Increases in sales and marketing costs each year are primarily due to
the increase in net subscriber additions. During 1998 the sales and marketing
cost per net subscriber added, including the loss on equipment sales, increased
to $752 from $574 in 1997. This increase is largely due to a growth in
disconnected subscribers causing the increase in costs to be spread over a
similar amount of net subscriber additions as in the prior year. The growth in
disconnected subscribers is a result of a similar churn rate (representing
customer attrition) applied to a larger subscriber base. Although sales and
marketing costs increased in 1997, sales and marketing cost per net subscriber
added, including the loss on equipment sales, decreased to $574 in 1997 from
$593 in 1996. Removing the effect of the Triad properties acquired in October
1997, sales and marketing costs would have been approximately $59.8 million in
1997 and the cost per net subscriber added, including the loss on equipment
sales, would have been $578.

        Cost of equipment sales increased each year due to the increase in the
number of handsets sold, offset by a decrease in the average cost of handsets
sold. VoiceStream expects this trend to continue in 1999. Although subscribers
generally are responsible for purchasing or otherwise obtaining their own
handsets, VoiceStream has historically sold handsets below cost to respond to
competition and general industry practice and expects to continue to do so in
the future.


        Increases in depreciation and amortization expense over the past three
years are primarily due to the purchase of additional wireless communications
system assets. In 1997, the increase in depreciation and amortization expense
caused by the purchase of additional assets, including the acquisition of the
Triad properties, was offset by the change in the life by which cellular
licenses are amortized. Effective January 1, 1997, Western Wireless
prospectively changed its amortization period for cellular licensing costs from
15 years to 40 years to conform more closely with industry practices. The effect
of this change in 1997 was to decrease net loss by approximately $15 million and
decrease the basic loss per share by $0.21.

        CELLULAR EBITDA

        The increase in cellular EBITDA is primarily a result of increased
revenues due to the increased subscriber base and the related cost efficiencies
gained. As a result, cellular operating margin (cellular EBITDA as a percentage
of cellular service revenues) increased to 38.7% in 1998 from 35.8% in 1997 and
28.3% in 1996.

        CELLULAR NET LOSS

        From 1997 to  1998, the increase in net loss is primarily attributable
to the increase in other expenses, offset by the continued improvements in
operating income. Western Wireless expects continued improvements in operating
income from 1998 to 1999. Net loss may not improve due to potential non-cash
stock option expenses related to the Spin-off. Net loss decreased in 1997 from
1996 due to the increase in revenues and operating efficiencies gained.



                                       32
<PAGE>   33
        CELLULAR OTHER INCOME (EXPENSE); NET OPERATING LOSS CARRYFORWARDS

        Interest and financing expense increased to $92.2 million in 1998 from
$41.4 million in 1997 and $41.1 million in 1996 due to the increase in long-term
debt. Long-term debt was incurred primarily to fund Western Wireless' capital
expenditures associated with the build-out and enhancements of the cellular
systems and the acquisition of wireless properties. The cellular weighted
average interest rate was 8.87% in 1998, 8.22% in 1997 and 7.79% in 1996.

        Western Wireless' cellular operations had available at December 31,
1998, net operating loss ("NOL") carryforwards of approximately $180 million
which will expire in the years 2002 through 2018. Western Wireless may be
limited in its ability to use these carryforwards in any one year due to
ownership changes that preceded the business combination that formed Western 
Wireless in July 1994. Management believes that, based on a number of factors,
there is sufficient uncertainty regarding the utilization of Western Wireless'
NOL carryforwards.

        CELLULAR LIQUIDITY AND CAPITAL RESOURCES

   
    

        Western Wireless has a credit facility (the "Cellular Credit Facility")
with a consortium of lenders providing for $750 million of revolving credit and
a $200 million term loan. As of December 31, 1998, $645 million was outstanding
under the Cellular Credit Facility. Indebtedness under the Cellular Credit
Facility matures on March 31, 2006, and bears interest at variable rates.
Substantially all the assets of Western Wireless, excluding the VoiceStream PCS
assets and certain other assets, are pledged as security for such indebtedness.
The terms of the Cellular Credit Facility restrict, among other things, the sale
of assets, distribution of dividends or other distributions and loans. Amounts
available for borrowing, which are limited by certain financial covenants and
other restrictions, were $305 million at December 31, 1998.

   
        Western Wireless has issued $200 million principal amount of 10-1/2% 
Senior Subordinated Notes Due 2006 (the "2006 Notes") at par and $200 million
principal amount of 10-1/2% Senior Subordinated Notes Due 2007 (the "2007 
Notes") at par. Indebtedness under the 2006 Notes and 2007 Notes matures in June
1, 2006 and February 1, 2007, respectively. The Credit Facility prohibits the 
repayment of all or any portion of the principal amounts of the 2006 Notes or 
2007 Notes prior to the repayment of all indebtedness under the Credit 
Facility. The 2006 and 2007 Notes contain certain restrictive covenants which 
impose limitations on the operations and activities of Western Wireless and 
certain of its subsidiaries, including the issuance of other indebtedness, the 
creation of liens, the sale of assets, issuance of preferred stock of 
subsidiaries and certain investments and acquisitions. Western Wireless will 
obtain the appropriate waivers from the holders of these notes prior to 
consummating the terms of the Spin-off.
    

        In February 1998, a subsidiary of Hutchison Telecommunications Limited
("HTL") purchased 19.9% of the outstanding capital stock of VoiceStream for an
aggregate purchase price of $248.4 million (the "Hutchison Investment").
Approximately $113 million of the proceeds were paid to Western Wireless as a
repayment of advances made to VoiceStream and were used by Western Wireless to
reduce amounts outstanding under the Cellular Credit Facility.

        Through the end of 1999, Western Wireless anticipates spending
significant capital resources for the acquisition of wireless assets and the
continued development of its existing infrastructure. In 1999, Western Wireless
expects to spend approximately $80 million for the continued expansion of its
cellular infrastructure and approximately $95 million for the purchase of the
cellular licenses and operations of the Brownsville, Texas and McAllen, Texas
MSAs. Western Wireless will utilize cash on hand, the Cellular Credit Facility
and other sources of funding, for purposes of funding its cellular and other
activities.

        In June 1998, WWI, through a controlling interest in a partnership (the
"Ireland Partnership"), was notified by the Irish Government that it was the
preferred applicant for a DCS-1800/GSM 900 mobile communication license in
Ireland. The amount bid by the Ireland Partnership on this license was $16.2
million, including related fees. The license has not yet been issued, as the
decision by the Irish Government is subject to a pending legal proceeding.

<PAGE>   34
        Adjustments to the $13.4 million cellular net loss to reconcile to net
cash used in operating activities primarily included $74.4 million of
depreciation and amortization, $44.0 million for the minority interest loss of
consolidated subsidiaries and $4.7 million for the equity in net loss of
unconsolidated affiliates due to the increase in activity in international
investments. Other adjustments included changes in operating assets and
liabilities, including: (i) an increase of $7.7 million in net accounts
receivable, due primarily to increased revenues; and (ii) a decrease of $5.0
million in inventory due to an effort to reduce inventory levels. Net cash used
in operating activities was $83.6 million in 1997 and $19.9 million in 1996.

        Cellular investing activities consisted primarily of: (i) purchases of
property and equipment of $73.4; (ii) investments in and advances to
unconsolidated affiliates of $15.5 million, primarily attributable to advances
to international joint ventures; (iii) $8.5 million of additions to licensing
costs and other intangible assets, primarily attributable to 36 Local Multipoint
Distribution Service (LMDS) licenses that Western Wireless acquired in an FCC
auction; and (iv) $35.3 million for acquisition of wireless properties in 1998
which consists primarily of Western Wireless' purchase of the cellular licenses
and operations of the Nebraska 5 and Colorado 4 RSAs in the second and third
quarters of 1998, respectively.

        Cellular financing activities primarily consisted of the net repayment
on long-term debt of $50.0 million.

        In the ordinary course of business, Western Wireless continues to
evaluate cellular acquisition opportunities, joint ventures and other potential
business transactions. Such acquisitions, joint ventures and business
transactions may be material. Such transactions may also require Western
Wireless to seek additional sources of funding through the issuance of
additional debt and/or additional equity at the parent or subsidiary level.
There can be no assurance that such funds will be available to Western Wireless
on acceptable or favorable terms.

        CELLULAR SEASONALITY

        Western Wireless, and the wireless communications industry in general,
have historically experienced significant subscriber growth during the fourth
calendar quarter. Accordingly, during such quarter Western Wireless experiences
greater losses on equipment sales and increases in sales and marketing expenses.
Western Wireless has historically experienced highest usage and revenue per
subscriber during the summer months. Western Wireless expects these trends to
continue.

VOICESTREAM PCS OVERVIEW

        VoiceStream did not commence operations in any of its markets until
February 1996. From that date through the end of 1996 VoiceStream launched
service in six markets: Honolulu, Portland, Salt Lake City, Albuquerque,
Oklahoma City and Des Moines. In 1997, VoiceStream launched service in El Paso,
Boise and Denver. In 1998, VoiceStream launched service in Phoenix/Tucson. Due
to the varying dates at which each of the markets became operational, the
expenses and revenues incurred during any period may not be comparable to
another period and may not be representative of future operations. Additionally,
during each period being discussed a portion of the operating expenses was
related to start-up costs incurred before the commencement of operations in each
of the markets. Exclusive of depreciation and amortization expense, which was
not material, approximately $7.7 million of start-up costs were incurred in
1998, $5.4 million in 1997 and $17.0 million in 1996.

        As Western Wireless owns its PCS operations through its 80.1% ownership
of VoiceStream, all discussion has been presented from the perspective of
VoiceStream, therefore, the following results of operations reflects 100% of
VoiceStream's consolidated PCS operations.

        RESULTS OF PCS OPERATIONS FOR THE YEARS ENDED DECEMBER 31, 1998, 1997,
AND 1996

        VoiceStream had 322,400 subscribers at December 31, 1998, a 150.7%
increase during 1998. VoiceStream had 128,600 subscribers at December 31, 1997,
a 262.3% increase during 1997. At December 31, 1996, VoiceStream had 35,500
subscribers.

</TABLE>
    

        PCS REVENUES

        The increase in subscriber revenues is due to the increase in the number
of subscribers. The increase in subscribers is due to the higher number of
operational markets during each period and the relative maturity of
VoiceStream's operations in these markets. Offsetting this increase is a
decrease in the average monthly subscriber revenue per average subscriber
("ARPU"). ARPU was $45.81 for 1998 compared to $57.48 for 1997 and $62.85 for
1996. The decrease in ARPU is primarily due to the change in strategy in 1998,
signified by the "Get More" advertising campaign. In this campaign, subscribers
get more value from their wireless service through lower priced rate plans that
include high minutes of use. Revenues from prepaid customers of $2.1 million are
included in subscriber revenues for 1998. VoiceStream does not expect that ARPU
will decline at the same rate in 1999 as it did in 1998.

        Roamer revenues are a result of VoiceStream's continuing effort to
procure domestic and international roaming agreements with other carriers. 
VoiceStream expects roamer revenues to increase in 1999 due to increased 
wireless subscribers and VoiceStream's expanded coverage.

        Equipment sales increased as a result of more handsets sold. The
increase in handsets sold is due to the number of operational markets during
each period and the relative maturity of VoiceStream's operations in these
markets. Offsetting this increase is a decrease in the average handset selling
price, which is the result of lower handset costs and the competitive
environment. VoiceStream anticipates continued growth in equipment sales as a
result of increases in subscriber additions and the commencement of commercial
operations in other markets.
        
        PCS OPERATING EXPENSES
        
        Cost of service expenses represent expenses incurred only by operational
markets. The increase in cost of service is primarily attributable to the
increased costs of maintaining the expanding wireless network as a result of new
markets becoming operational. Cost of service as a percentage of service
revenues declined to 40.0% in 1998 from 82.7% in 1997 and 160.0% in 1996 due to
efficiencies gained from the growing subscriber base. While cost of service
expenses are expected to grow in 1999 due to the growth in subscribers and
operating markets, VoiceStream expects the cost of service as a percentage of
service revenue to decline as greater economies of scale are realized.

        Cost of equipment sales increased each year due to the increase in
handsets sold, offset by a decrease in the average cost of handsets sold. 
VoiceStream expects this trend to continue in 1999. Although subscribers 
generally are responsible for purchasing or otherwise obtaining their own 
handsets, VoiceStream has historically sold handsets below cost to respond to 
competition and general industry practice and expects to continue to do so in 
the future.

        The increase in general and administrative expenses is primarily
attributable to the increased costs associated with supporting a larger
subscriber base. General and administrative costs per average subscriber were
$27.84 for 1998 compared to $56.74 for 1997 and $135.81 for 1996. This decrease
is largely the result of efficiencies gained from a larger subscriber base.
While general and administrative expenses are expected to grow in 1999 due to
the growth in subscribers and operating markets, VoiceStream expects the costs
per average subscriber to decline as greater economies of scale are realized.



                                       35


<PAGE>   36
        The increase in sales and marketing costs each year is primarily due to
the increase in subscribers added. Sales and marketing costs per net subscriber
added, including the loss on equipment sales, was $630 for 1998 compared to $943
for 1997 and $1,200 for 1996. This decrease is largely the result of
efficiencies gained from larger subscriber additions. Sales and marketing costs
are expected to increase in 1999 due to the anticipated growth in subscriber
additions.

        The increase in depreciation and amortization expenses is attributable
to the continued expansion of the wireless systems. FCC licenses are not
amortized until the related market is operational. These expenses will increase
as new markets become operational.

        PCS EBITDA

        From 1997 to  1998, the decrease in negative EBITDA is attributable to
the increase in revenues and operating efficiencies gained from the growing
subscriber base. VoiceStream expects a similar trend in EBITDA from 1999 for its
operational markets, however the commencement of operations in new markets will
slow and could reverse this trend. Negative EBITDA increased in 1997 from 1996
due to the commencement of operations in three new markets.

        PCS NET LOSS

        From 1997 to  1998, the decrease in net loss is attributable to the
increase in revenues, operating efficiencies gained from growing the subscriber
base and a decrease in other expense. VoiceStream expects a similar trend in net
loss from 1998 to 1999 for its operational markets, however the commencement of
operations in new markets will slow and could reverse this trend. Net loss
increased in 1997 from 1996 due to the commencement of operations in new
markets.

        PCS OTHER INCOME (EXPENSE); NET OPERATING LOSS CARRYFORWARDS

        Interest and financing expense, net of capitalized interest, decreased
in 1998 from 1997 due to the equity contributions from Western Wireless in
December 1997 and Hutchison USA in February 1998 (see "PCS Liquidity and 
Capital Resources"). The equity contribution from Western Wireless was a
conversion of debt that had previously incurred interest. The Hutchison
Investment allowed VoiceStream to repay the remaining debt to Western Wireless
and to forego additional borrowings until July 1998. The increase in interest
and financing expense in 1997 from 1996 was due to the increase in long-term
debt. Long-term debt was incurred primarily to fund the capital expenditures
associated with the build-out of the wireless systems. Interest expense will
increase in 1999 as a result of increased borrowings to fund the expansion of
the wireless network. The weighted average interest rate, before the effect of
capitalized interest, was 8.76% in 1998, 8.23% in 1997 and 8.12% in 1996. 
Interest income and other increased in 1998 from 1997 due to interest 
earned on the funds received in the Hutchison Investment.

        VoiceStream had $707 million of NOL carryforwards at December 31, 1998,
which will expire between 2010 and 2018. After the Spin-off, these NOL
carryforwards will remain with VoiceStream. Management believes that, based on a
number of factors, there is sufficient uncertainty regarding the utilization of
VoiceStream's NOL carryforwards.

        PCS LIQUIDITY AND CAPITAL RESOURCES

   
    

        VoiceStream, through a wholly-owned subsidiary, has a credit facility
with a consortium of lenders (the "PCS Credit Facility") consisting of $500
million in revolving credit and $500 million in term loans. As of December 31,
1998, $540 million was outstanding under the PCS Credit Facility. The amount 
which VoiceStream can borrow under the Credit Facility is reduced beginning on 
2001, the same year in which repayment of the Credit Facility begins. Debt under
the PCS Credit Facility matures on December 31, 2006, for the revolver and the
delayed draw term loan, and June 30, 2007, for the other $250 million term loan.
The borrowings under the PCS Credit Facility bear interest at variable rates.
Substantially all the assets of VoiceStream, other than certain PCS licenses
acquired in the FCC's D and E Block auctions and certain other assets, are
pledged as security for such debt. The terms of the PCS Credit Facility
restrict, among other things, the sale of assets, distribution of dividends or
other distributions and loans. As of January 1, 1999, the amount available to
borrow under the PCS Credit Facility, which is restricted by certain financial
covenants, was $277 million.


                                       36
<PAGE>   37
        The Hutchison Investment closed in February 1998. Approximately $135
million of the proceeds of the Hutchison Investment was used by VoiceStream for
the build-out of its systems during 1998. The remainder of the proceeds was paid
to Western Wireless as a repayment of loans made to VoiceStream.

   
        In 1999, VoiceStream anticipates spending approximately $150 million for
the continued expansion of its operating markets and $150 million for the
development and expansion of new markets (both amounts include VoiceStream's
anticipated spending by Cook Inlet PCS). VoiceStream will use cash on hand and
amounts available for borrowing under the PCS Credit Facility for such purposes.
In addition, further funds (which may be significant) will be required to
finance the continued growth of its operations, including the build-out of its
markets, provide for working capital and service debt. The build-out of
additional systems by VoiceStream will require substantial additional funds. The
capital cost of completing the project in any particular market, and overall,
could vary materially from current estimates. If adequate funds are not
available from its existing capital resources, VoiceStream may be required to
curtail its service operations or to obtain additional funds. The terms of any
additional funds may be less favorable than those contained in current
arrangements. In addition to the aforementioned capital expenditures,
VoiceStream expects to make in 1999, VoiceStream has noncancellable lease
agreements for various facilities, including cell-site locations, of
approximately $25 million in 1999. The sources of funding for such expenditures
will come from the same sources as discussed above. VoiceStream has reached an
agreement in principle with one of its infrastructure equipment vendors whereby
such vendor would purchase $400 million of VoiceStream's newly designated and
issued 12% cumulative senior exchangeable preferred stock. During the first five
years following issuance, dividends would be paid in cash or, at VoiceStream's
option, in additional shares of exchangeable preferred stock having an aggregate
liquidation preference equal to the amount of such dividends. After the fifth
anniversary, all dividends would be payable only in cash. In addition,
VoiceStream would modify its existing PCS supply agreement with such vendors.
The agreement in principle contemplates that the net proceeds of the sale of the
exchangeable preferred stock would be used to finance capital expenditures, for
working capital purposes and to finance permitted investments and acquisitions.
Although VoiceStream is working diligently with the vendor to prepare formal
contracts, there can be no assurance that formal contracts will be executed and
that such funds will be available to VoiceStream.
    

        A wholly owned subsidiary of VoiceStream holds a 49.9% interest in Cook
Inlet PCS. Cook Inlet PCS is subject to the FCC's build-out requirements and
will require significant additional amounts to complete the build-out of its PCS
systems and to meet the government debt service requirements on its C and F
Block licenses. No principal payments on these licenses are due in 1999. The
potential sources of such additional funding include vendor loans, loans or
capital contributions by the partners of Cook Inlet PCS or other third party
financing. To date, Western Wireless has funded the operations of Cook Inlet PCS
through the issuance of promissory notes. VoiceStream does not have any further
commitments to fund Cook Inlet PCS. At December 31, 1998, Western Wireless had
advanced funds totaling $65.3 million to Cook Inlet PCS under such promissory
notes. During the second quarter of 1998, Cook Inlet PCS participated in the C
Block restructuring options provided by the FCC. The options chosen by Cook
Inlet PCS had the effect of reducing its debt by $29.1 million.

   
        In January 1999, certain partners of Cook Inlet PCS, including
VoiceStream, formed another joint venture, Cook Inlet/VoiceStream PCS LLC
("CIVS") (of which 49.9% is owned by VoiceStream and 50.1% is owned by Cook
Inlet Region, Inc.) to participate in the FCC's reauction of C and F Block 
licenses in 1999. VoiceStream contributed $25 million in March of 1999, to the 
deposit required by the FCC to participate in the reauction. CIVS has reached 
an agreement in principle with one of its infrastructure equipment vendors 
whereby such vendor would provide to CIVS a $725 million senior credit facility
and a $100 million subordinated facility, and would agree to acquire certain 
equipment, software and services from such vendor. The agreement in principle 
contemplates that the net proceeds of the senior secured facility and the 
subordinated facility would be used to finance capital expenditures, for 
working capital and to finance permitted investments and acquisitions. The 
effectiveness of the senior secured facility and the subordinated facility will
be conditioned upon CIVS acquiring licenses for BTA's covering at least 2 
million persons. The amount available for borrowing pursuant to the senior 
credit facility and the subordinated facility will be based upon the aggregate
number of persons covered by licenses for BTA's acquired by CIVS, with $825 
million in the aggregate being available if CIVS acquires licenses for BTA's 
covering at least 15 million persons and such availability being ratably
reduced if CIVS acquired licenses for BTA's covering fewer than 15 million 
persons. Although CIVS is working diligently with the vendor to prepare formal
contracts, there can be no assurance that formal contracts will be executed or
that such funds will be available to CIVS.
    

        After the Spin-off, the NOL carryforwards resulting from VoiceStream's
cumulative tax losses will remain with VoiceStream. Pursuant to a tax sharing
agreement entered into at the time of the Hutchison Investment, VoiceStream will
pay Western Wireless in 1999 an amount representative of the tax benefit of NOLs
generated while VoiceStream was a wholly-owned subsidiary of Western Wireless.
This payment will not exceed $20 million, net of taxes.

        Net cash used in operating activities was $112.9 million in 1998.
Adjustments to the $254.3 million net loss to reconcile to net cash used in
operating activities included $83.8 million of depreciation and amortization,
and $24.1 million for equity in the net loss of unconsolidated subsidiaries.
Other adjustments included changes in operating assets and liabilities,
including: (i) an increase of $20.9 million in accrued liabilities, the largest
component of which is attributable to an increase in property taxes; and (ii) an
increase of $13.7 million in accounts payable, due to the growth of the
business. Net cash used in operating activities was $198.1 million in 1997 and
$81.3 million in 1996.

        Net cash used in investing activities was $253.6 million in 1998.
Investing activities consisted primarily of: (i) purchases of property and
equipment of $206.5 million, largely related to the build-out of the wireless
network; (ii) investments in and advances to unconsolidated affiliates of $34.3
million, primarily attributable to advances to Cook Inlet PCS for working
capital and purchases of property and equipment; and (iii) $12.9 million of
additions to licensing costs and other intangible assets, primarily attributable
to 16 Local Multipoint Distribution Service (LMDS) licenses acquired in an FCC
auction. Net cash used in investing activities was $370.2 million in 1997 and
$342.6 million 1996.

        Net cash provided by financing activities was $374.3 million in 1998.
Financing activities consisted of: (i) net proceeds from the Hutchison
Investment of $244.8 million, offset by the repayment of advances from Western
Wireless of $105.4 million; and (ii) net borrowings on long-term debt of $240.0
million, offset by $5.1 million of financing fees. Net cash provided by
financing activities was $563.3 million in 1997 and $429.3 million in 1996.

        In the ordinary course of business, VoiceStream continues to evaluate
acquisitions, joint ventures and other potential business transactions. Any such
transactions would be financed with the borrowings under the Credit Facility or
through the issuance of additional debt or the sale of additional equity. There
can be no assurance that such funds will be available to VoiceStream on
acceptable or favorable terms.

PCS SEASONALITY

        VoiceStream, and the wireless communications industry in general, have
historically experienced significant subscriber growth during the fourth
calendar quarter. Accordingly, during such quarter VoiceStream experiences
greater losses on equipment sales and increases in sales and marketing expenses.
VoiceStream expects this trend to continue.

WESTERN WIRELESS AND ITS SUBSIDIARIES YEAR 2000 ISSUES

   
     Western Wireless, like most businesses, will be required to modify
significant portions of its information technology ("IT") and non-IT systems so
that they will function properly in the year 2000. Any of Western Wireless', or
its vendors', IT and non-IT systems that have date-sensitive software may
recognize a date using "00" as the year 1900 rather than as the year 2000.
Western Wireless' IT and non-IT systems that are being addressed include: its
wireless networks; systems which interconnect its wireless networks with
landline systems; systems which allow verification and billing of roaming
traffic; internal communications and data processing systems; billing software
and related elements; and systems of third-party suppliers, including those of
financial institutions, payroll/benefits processors and credit bureaus.
    

     Much of Western Wireless' technology, including technology associated with
its critical systems, is purchased from third parties. Western Wireless is
dependent on those third parties to assess the impact of the year 2000 issue on
the technology and services they supply and to take any necessary corrective
action. Western Wireless cannot assure that these third parties will
have taken the necessary corrective action prior to the year 2000.

   
     Western Wireless has adopted a remediation plan to become year 2000
compliant. This plan consists of four key phases: (1) inventory of all systems,
(2) research, including obtaining information from third party suppliers
to determine whether they have accurately assessed the problem and taken
corrective action, (3) implementation and testing of remediation efforts, and
(4) development of contingency plans. Western Wireless has completed the first
two phases of its plan and is currently testing and remediating its critical
systems and developing contingency plans to address the year 2000 issue.
Western Wireless expects to substantially complete the third and fourth phases
by the end of the third quarter of 1999. Critical systems are those whose 
failure poses a risk of disruption to Western Wireless' ability to provide 
wireless services, to collect revenues, to meet safety standards, or to comply 
with legal requirements. Western Wireless expects to incur internal staff costs
as well as consulting and other expenses related to infrastructure and 
facilities enhancements necessary to complete the remediation of the systems 
for the year 2000. Western Wireless cannot assure that the remediation of its 
critical systems will be complete by the year 2000.
    


     While costs incurred to date to address the year 2000 issue have not been
significant, Western Wireless expects to incur incremental expenses of not more 
than $5 million through the end of 1999 to implement its plan for its critical
systems. In addition, Western Wireless has redeployed internal resources to
address the problem. The majority of these expenses will be incurred in the
first half of 1999. Additionally, Western Wireless will incur capitalized costs
that represent ongoing investment in new systems and system upgrades, 
the timing of which is being accelerated to facilitate year 2000 compliance and
which is not expected to have a material impact on Western Wireless' financial
position or results of operations. This estimate assumes that third party  
suppliers have accurately assessed the compliance of their products and that 
they will successfully correct the issue in non-compliant products. Because of 
the complexity of correcting the year 2000 issue, actual costs may vary from 
this estimate.

   
     Based on its current assessments and its remediation plan, which are based
in part upon certain representations of third parties, Western Wireless expects
that it will not experience a disruption of its operations as a result of the
arrival of the year 2000. However, there can be no assurance that either Western
Wireless or the third parties who have supplied technology used in Western
Wireless' critical systems will be successful in taking corrective action in a
timely manner. As part of its plan, Western Wireless has developed, and is
continuing to develop, contingency plans for its critical systems, which
include, among other things, identifying a core system of cell sites which are
being designed to operate for extended periods for mobile to mobile service 
independent of external power supplies and landline telephone services. Western
Wireless believes that these contingency plans will mitigate service
disruption; however, Western Wireless cannot guarantee this.

Western Wireless will continuously test and update these plans
and systems as long as necessary.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To the Board of Directors and Shareholders of
Western Wireless Corporation:

We have audited the accompanying consolidated balance sheets of Western Wireless
Corporation and subsidiaries as of December 31, 1998 and 1997, and the related
consolidated statements of operations and comprehensive loss, shareholders'
equity and cash flows for each of the three years in the period ended December
31, 1998. These financial statements and schedules referred to below are the
responsibility of Western Wireless management. Our responsibility is to express
an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
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 financial statements referred to above present fairly, in
all material respects, the financial position of Western Wireless Corporation
and subsidiaries as of December 31, 1998 and 1997, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1998, in conformity with generally accepted accounting principles.

Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The schedules listed in the index of
consolidated financial statements are presented for purposes of complying with
the Securities and Exchange Commission rules and are not a required part of the
basic financial statements. These schedules have been subjected to the auditing
procedures applied in our audits of the basic financial statements and, in our
opinion, are fairly stated in all material respects in relation to the basic
financial statements taken as a whole.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. ORGANIZATION:

        Western Wireless Corporation ("Western Wireless") provides wireless
communications services in the United States principally through the ownership
and operation of cellular and personal communications services ("PCS") systems.
Western Wireless provides cellular operations primarily in rural areas in 17
western states under the Cellular One(R) brand name. Western Wireless provides
PCS services through its 80.1% ownership in VoiceStream Wireless Corporation
("VoiceStream"). VoiceStream has commenced commercial operations in ten markets
under the VoiceStream(R) brand name using the GSM technology. Additionally,
VoiceStream PCS services are offered in three additional markets in conjunction
with joint ventures.

        Through international joint ventures, Western Wireless International
("WWI"), a subsidiary of Western Wireless, has interests in (and in some cases
manages) wireless licenses in certain foreign countries, including Gahna,
Iceland, Haiti, Croatia and the Republics of Latvia and Georgia. In addition,
WWI has interests in entities which have made wireless license applications in
certain other foreign countries.

        On February 8, 1999, Western Wireless announced its intention to
separate VoiceStream from Western Wireless' other operations (the "Spin-off").
Western Wireless has received a favorable ruling by the Internal Revenue Service
for a tax free spin-off, and the approval by its board of directors to take the
necessary steps to complete the Spin-off. Western Wireless will distribute all
of its interest in VoiceStream to its shareholders upon the Spin-off. Although
VoiceStream has been operated separately from Western Wireless' other operations
and has been a separate legal entity since its inception, the Spin-off will
establish VoiceStream as a stand-alone entity with objectives separate from
those of Western Wireless. The Spin-off is subject to numerous conditions
including, among others, the receipt of certain government and third party
approvals. There is no assurance that such conditions will be met to complete
the Spin-off.

        Western Wireless expects that VoiceStream will incur significant
operating losses and generate negative cash flows from operating activities
during the next several years while it expands its PCS systems and customer
base.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

        Principles of consolidation:

   
        The consolidated financial statements include the accounts of Western
Wireless, its wholly owned subsidiaries and its affiliate investments in which
Western Wireless has a greater than 50% interest. All affiliate investments in
which Western Wireless has between a 20% and 50% interest are accounted for
using the equity method. All significant intercompany accounts and transactions
have been eliminated.
    

        Cash and cash equivalents:

        Cash and cash equivalents generally consist of cash and marketable
securities that have original maturity dates not exceeding three months. Such
investments are stated at cost, which approximates fair value.

        Revenue recognition:

        Service revenues based on customer usage are recognized at the time the
service is provided. Access and special feature service revenues are recognized
when earned. Sales of equipment, primarily handsets, are recognized when the
goods are delivered to the customer.

        Inventory:

        Inventory consists primarily of handsets and accessories. Inventory is
stated at the lower of cost or market, determined on a first-in, first-out
basis.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED):

        Property and equipment and depreciation:

        Property and equipment are stated at cost. Depreciation commences once
the assets have been placed in service and is computed using the straight-line
method over the estimated useful lives of the assets which primarily range from
three to twenty years.

        Licensing costs and other intangible assets and amortization:

        Licensing costs primarily represent costs incurred to acquire Federal
Communication Commission's ("FCC") wireless licenses, including cellular
licenses principally obtained through acquisitions, and PCS licenses primarily
purchased from the FCC.

        Amortization of cellular licenses is computed using the straight-line
method. Effective January 1, 1997, Western Wireless prospectively changed its
amortization period for cellular licensing costs from 15 years to 40 years to
conform more closely with industry practices. The effect of this change in 1997
was to decrease net loss by approximately $15 million and decrease the loss per
share by $0.21. Amortization of PCS licenses begins with the commencement of
service to customers and is computed using the straight-line method over 40
years.

        Other intangible assets consist primarily of deferred financing costs.
Deferred financing costs are amortized using the effective interest method over
the terms of the respective loans.

        In accordance with Statement of Financial Accounting Standards ("SFAS")
No. 121, "Accounting for the Impairment of Long-lived Assets and for Long-lived
Assets to be Disposed of," Western Wireless periodically evaluates whether there
has been any indication of impairment of its long-lived assets, including its
licensing costs and other intangibles. As of December 31, 1998, there has been
no indication of such impairment.

        Capitalized Interest:

        VoiceStream PCS licenses and wireless communications systems represent
qualified assets pursuant to SFAS No. 34, "Capitalization of Interest Cost."
VoiceStream capitalized interest of $1.8 million in 1998 and $4.0 million in
1997.

        Income taxes:

        Deferred tax assets and liabilities are recognized based on temporary
differences between the financial statements and the tax bases of assets and
liabilities using enacted tax rates expected to be in effect when they are
realized. A valuation allowance against deferred tax assets is recorded, if,
based upon weighted available evidence, it is more likely than not that some or
all of the deferred tax assets will not be realized.

        Loss per common share:

        Loss per common share is calculated using the weighted average number of
shares of outstanding common stock during the period. The number of shares
outstanding has been calculated based on the requirements of SFAS No. 128,
"Earnings Per Share." Due to the net loss incurred during the periods presented,
all options outstanding are anti-dilutive, thus basic and diluted loss per share
are equal.

        Stock-based compensation plans:

        Western Wireless accounts for its stock-based compensation plans under
APB Opinion No. 25, "Accounting for Stock Issued to Employees." See Note 12 for
discussion of the effect on net loss and other related disclosures had Western
Wireless accounted for these plans under SFAS No. 123, "Accounting for
Stock-Based Compensation."

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED):

        Foreign currency translation:

        For operations outside the United States that prepare financial
statements in currencies other than the United States dollar, results of
operations and cash flows are translated at average exchange rates during the
period, and assets and liabilities are translated at end of period exchange
rates. Translation adjustments are included as a separate component of
shareholders' equity.

        Fair value of financial instruments:

        As required under the Cellular and PCS Credit Facilities (as defined in
Note 7), Western Wireless enters into interest rate swap and cap agreements to
manage interest rate exposure pertaining to long-term debt. Western Wireless has
only limited involvement with these financial instruments, and does not use them
for trading purposes. In addition, Western Wireless has historically held
derivative financial instruments to maturity and has never recognized a material
gain or loss on disposal. It is Western Wireless' intent to hold existing
derivatives to maturity. Interest rate swaps are accounted for on an accrual
basis, the income or expense of which is included in interest expense. Premiums
paid to purchase interest rate cap agreements are classified as an asset and
amortized to interest expense over the terms of the agreements. These
transactions do not subject Western Wireless to risk of loss because gains and
losses on these contracts are offset against losses and gains on the underlying
liabilities. No collateral is held in relation to financial instruments.

        The carrying value of short-term financial instruments approximates fair
value due to the short maturity of these instruments. The fair value of
long-term debt is based on incremental borrowing rates currently available on
loans with similar term and maturities. Western Wireless does not hold or issue
any financial instruments for trading purposes.

        Supplemental cash flow disclosure:

        Cash paid for interest (net of amounts capitalized) was $123.2 million
in 1998, $87.4 million in 1997 and $36.2 million in 1996.

        Non-cash investing and financing activities were as follows:

</TABLE>



        Estimates used in preparation of financial statements:

        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 amounts of revenues and expenses during the
reporting periods. Actual results could differ from those estimates.

        Reclassifications:

        Certain amounts in prior year's financial statements have been
reclassified to conform to the 1998 presentation.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED):

        Recently issued accounting standards:

        In June 1998, the Financial Accounting Standards Board issued SFAS No.
133, "Accounting for Derivative Instruments and Hedging Activities." It requires
the recognition of all derivatives as either assets or liabilities and the
measurement of those instruments at fair value. The required adoption period is
effective for the issuance of Western Wireless' March 31, 2000, quarterly
financial statements. The implementation of SFAS No. 133 is not expected to have
a material impact on Western Wireless' financial position or results of
operations.

        The American Institute of Certified Public Accountants recently issued
Statement of Position (SOP) 98-5, "Reporting on the Costs of Start-Up
Activities." This SOP provides guidance on the financial reporting of start-up
costs and organizational activities. It requires costs of start-up activities
and organizational costs to be expensed as incurred. SOP 98-5 is not expected to
materially affect the financial position or results of operations of Western
Wireless. The required adoption period is effective for the issuance of Western
Wireless' December 31, 1999, financial statements

        Western Wireless' ownership interest in these unconsolidated affiliates
range from 18% to 50%.
    

        VoiceStream Investments:

        A subsidiary of VoiceStream holds a 49.9% interest in Cook Inlet Western
Wireless PV/SS PCS, L.P. ("Cook Inlet PCS"). Cook Inlet PCS is subject to the
FCC build-out requirements and will require significant additional amounts to
complete the build-out of its PCS systems and to meet the government debt
service requirements on its C and F Block licenses. The potential sources of
such additional funding include vendor loans, loans or capital contributions by
the partners of Cook Inlet PCS or other third party financing. VoiceStream
funded the operations of Cook Inlet PCS during 1998 and 1997 through loans
evidenced by promissory notes which are due 180 days after the date of issuance.
The weighted average interest rate was 15% for 1998 and 1997. All promissory
notes that have come due were replaced with new promissory notes.

        During the second quarter of 1998, Cook Inlet PCS participated in the C
Block restructuring options provided by the FCC. The FCC provided for various
options, including: (1) to return to the FCC entire licenses purchased in the C
Block auction and be relieved of 100% of the related debt ("Amnesty"); and (2)
to return 15 MHz, from a total of 30 MHz, of the licenses purchased in the
auction and be relieved of one half of the related debt ("Disaggregation"). Of
the licenses purchased in the C Block auction, Cook Inlet PCS chose Amnesty for
two Basic Trading Area ("BTA") licenses and Disaggregation for 11 BTA licenses.
This resulted in a reduction of Cook Inlet PCS's debt of $29.1 million and a
gain of $3.9 million, due to the retroactive adjustment of interest accrued on
the related debt, the effect of which reduced the equity losses picked up by
VoiceStream for the second quarter.

        In September 1997, a wholly owned subsidiary of VoiceStream and a
subsidiary of Iowa Network Services, Inc., formed a limited partnership ("Iowa
Wireless") to build and operate a PCS network under the VoiceStream brand name
covering certain metropolitan areas in Iowa and the major interstate and state
highways linking such areas. In 1998, VoiceStream contributed certain licenses
that it purchased in the FCC's A and D Block auctions for approximately $12.3
million to the venture for an approximate 38% ownership interest.

        Western Wireless International Investments:

        In October 1998, a joint venture in which, WWI owns a 19.0% minority
interest was granted a license to provide wireless communication services in
Croatia. WWI contributed $3.3 million for the purchase of the license.

        In September 1998, a joint venture in which, WWI owns a 28.5% minority
interest was granted a license to provide wireless communication services in
Haiti. WWI contributed $8.5 million for the purchase of the license.

5. INVESTMENTS IN AND ADVANCES TO UNCONSOLIDATED AFFILIATES (CONTINUED):

        In June 1998, WWI, through a controlling interest in a partnership (the
"Ireland Partnership"), was notified by the Irish Government that it was the
preferred applicant for a DCS-1800/GSM 900 mobile communication license in
Ireland. The amount bid by the Ireland Partnership on this license was $16.2
million, including related fees. The license has not yet been issued, as the
decision by the Irish Government is subject to a pending legal proceeding.

</TABLE>

        Cellular Credit Facility:

        Western Wireless has a credit facility with a group of banks (the
"Cellular Credit Facility") pursuant to which the banks agreed to make loans to
Western Wireless, on a revolving-credit basis, in an aggregate principal amount
not to exceed $750 million (the "Cellular Revolver") and a term loan (the
"Cellular Term Loan") of $200 million. The Cellular Revolver is limited to the
principal amount outstanding on December 31, 2000. Western Wireless is required
to make quarterly payments on the outstanding principal of the Cellular Revolver
beginning March 31, 2001, and on the Cellular Term Loan beginning June 30, 2001.
These payments increase each year on the anniversary date of the initial
payment, until paid in full on December 31, 2005, for the Cellular Revolver and
March 31, 2006, for the Cellular Term Loan. The Cellular Credit Facility also
contains certain financial covenants, the most restrictive of which impose
limitations on the incurrence of indebtedness.

        Under the Cellular Credit Facility, interest is payable at an applicable
margin in excess of a prevailing base rate. The prevailing rate is based on the
prime rate, the CD rate or LIBOR. The applicable margin on the Cellular Revolver
is determined quarterly based on the leverage ratio of Western Wireless,
excluding certain of its subsidiaries. The applicable margin on the Cellular
Term Loan is 2.5%. During 1998 and 1997, all loans under the Cellular Credit
Facility had been borrowed using the LIBOR option. The weighted average interest
rate, including the appropriate applicable margin, was 7.57% in 1998 and 8.22%
in 1997. The Cellular Credit Facility also provides for an annual fee ranging
from 0.25% to 0.375% on the unused commitment, payable quarterly.

        The repayment of the Cellular Credit Facility is secured by, among other
things, the grant of a security interest in substantially all of the assets of
Western Wireless, excluding, among other items, the capital stock and assets of
VoiceStream.

        The Cellular Credit Facility requires Western Wireless to enter into
interest rate swap and cap agreements to manage the interest rate exposure
pertaining to borrowings under the Cellular Credit Facility. Western had entered
into interest rate caps and swaps with a total notional amount of $325 million
at December 31, 1998, and $365 million at December 31, 1997. Generally these
instruments have initial terms ranging from three to 3-1/2 years and effectively
convert variable rate debt to fixed rate. The weighted average interest rate
under these agreements was approximately 7.67% in 1998 and 7.40% in 1997. The
amount of unrealized loss attributable to changing interest rates at December
31, 1998 and 1997, was immaterial.

7. LONG-TERM DEBT - (CONTINUED):

        PCS Credit Facility:

        In June 1998, a wholly owned subsidiary of VoiceStream (the "PCS
Borrower") entered into a $1 billion credit facility with a consortium of
lenders (the "PCS Credit Facility"). The PCS Credit Facility consists of $500
million in revolving credit and $250 million in a delayed draw term loan
(collectively the "PCS Revolver"), and a term loan (the "PCS Term Loan") for
$250 million. Beginning September 2001, the amount available to borrow under the
PCS Revolver and the principal balance of the PCS Term Loan are to be reduced by
various percentages each year. The PCS Revolver and the PCS Term Loan are due in
their entirety on December 31, 2006, and June 30, 2007, respectively. The PCS
Credit Facility also contains certain financial covenants, which, among other
things, impose limitations on the amount of indebtedness, limit the amount of
capital spending and impose limitations on acquisitions and investments. The
repayment of the PCS Credit Facility is secured by, among other things, the
grant of a security interest in substantially all of the assets of the PCS
Borrower and its subsidiaries.

        Under the PCS Credit Facility, interest is payable at an applicable
margin in excess of a prevailing rate. The prevailing rate is based on the prime
rate or LIBOR at the PCS Borrower's option. The applicable margin on the PCS
Credit Facility is determined quarterly based on certain events and the leverage
ratio of the PCS Borrower. The weighted average interest rate on all of
VoiceStream's debt, including the appropriate margin, was 8.76% in 1998 and
8.20% in 1997. As of December 31, 1998, all loans under the PCS Credit Facility
had been borrowed using the LIBOR option. The PCS Credit Facility also provides
for an annual fee ranging from 0.375% to 0.5% on the unused commitment, payable
quarterly.

        The PCS Credit Facility requires VoiceStream to enter into interest rate
swap and cap agreements to manage the interest rate exposure pertaining to
borrowings under the PCS Credit Facility. VoiceStream had entered into interest
rate caps and swaps with a total notional amount of $295 million at December 31,
1998. Generally these instruments have initial terms ranging from 1 to 4 years
and effectively convert variable rate debt to fixed rate. The weighted average
interest rate under these agreements was approximately 6.11% in 1998. The amount
of unrealized gain or loss attributable to changing interest rates at December
31, 1998, was not material.

        Interest only payments are required through June 30, 2001. Commencing
September 30, 2001, and at the end of each calendar quarter thereafter,
VoiceStream is required to make payments on the principal amount outstanding
under the PCS Credit Facility in increasing quarterly installments.

        Immediately after entering into the PCS Credit Facility, VoiceStream
paid off, in its entirety, the balance owed under the $300 million PCS Vendor
Facility.

        10-1/2% Senior Subordinated Notes Due 2006:

        In May 1996, Western Wireless issued at par $200 million of 10-1/2%
Senior Subordinated Notes that mature on June 1, 2006 (the "2006 Notes").
Interest is payable semi-annually. The 2006 Notes may be redeemed at any time at
the option of Western Wireless, in whole or from time to time in part, at
varying redemption prices. The Cellular and PCS Credit Facilities prohibit the
repayment of all or any portion of the principal amount of the 2006 Notes prior
to the repayment of all indebtedness under each credit facility. The 2006 Notes
contain certain restrictive covenants which impose limitations on the operations
and activities of Western Wireless and certain of its subsidiaries, including
the incurrence of other indebtedness, the creation of liens, the sale of assets,
issuance of preferred stock of subsidiaries, and certain investments and
acquisitions. The 2006 Notes are subordinate in right of payment to the Cellular
Credit Facility and the PCS Credit Facility.

        10-1/2% Senior Subordinated Notes Due 2007:

        In October 1996, Western Wireless issued at par $200 million of 10-1/2%
Senior Subordinated Notes that mature on February 1, 2007 (the "2007 Notes").
Interest is payable semi-annually. The 2007 Notes were issued pari passu to the
2006 Notes. As such, the 2007 Notes may be redeemed at any time at the option of
Western Wireless, in whole or from time to time in part, at varying redemption
prices. The Cellular and PCS Credit Facilities prohibit repayment of all or any
portion of the principal amount of the 2007 Notes prior to the repayment of all
indebtedness under each credit facility. The 2007 Notes contain certain
restrictive covenants which are consistent with that of the 2006 Notes. The 2007
Notes are subordinate in right of payment to the Cellular Credit Facility and
the PCS Credit Facility.

8. COMMITMENTS:

        Western Wireless leases various facilities, cell site locations,
rights-of-way and equipment under operating lease agreements. The leases expire
at various dates through the year 2027. Some leases have options to renew for
additional periods up to 25 years. Certain leases require Western Wireless to
pay property taxes, insurance and normal maintenance costs. Substantially all of
Western Wireless' leases have fixed minimum lease payments. Western Wireless has
no significant capital lease liabilities.

        Future minimum payments required under operating leases and agreements
that have initial or remaining noncancellable terms in excess of one year as of
December 31, 1998, are summarized below (dollars in thousands):

        Aggregate rental expense for all operating leases was approximately
$33.5 million in 1998, $28.0 million in 1997 and $14.2 million in 1996.

        In order to ensure adequate supply and availability of certain inventory
requirements and service needs, Western Wireless has committed to purchase from
various suppliers wireless communications equipment and services. These
agreements expire at various dates through December 2005. The aggregate amount
of these commitments total approximately $550 million. At December 31, 1998,
Western Wireless has ordered approximately $409 million under all of these
agreements, of which approximately $14 million is outstanding.

</TABLE>

        Western Wireless had available at December 31, 1998, net operating loss
("NOL") carryforwards of approximately $887 million. Of this amount,
approximately $707 million is related to cumulative losses incurred by
VoiceStream from its PCS operations. The NOL carryforwards will expire between
2002 and 2018. Western Wireless may be limited in its ability to use these
carryforwards in any one year due to ownership changes that preceded the
business combination that formed Western Wireless in July 1994. The change in
the valuation allowance increased $103 million in 1998, $107 million in 1997 and
$56 million in 1996.

        Management believes that the available objective evidence creates 
sufficient uncertainty regarding the realization of the net deferred tax assets.
Such factors include recurring operating losses resulting primarily from the
development of VoiceStream's PCS business and expected increased competition
from new entrants into Western Wireless' cellular markets. Accordingly, a
valuation allowance has been provided for the net deferred tax assets of Western
Wireless.

        The difference between the statutory tax rate of approximately 40% (35%
federal and 5% state, net of federal benefits) and the tax benefit of zero
recorded by Western Wireless is primarily due to the full valuation allowance
against net deferred tax assets. Western Wireless' ability to utilize the NOL
carryforwards in any given year may be limited by certain events, including a
significant change in ownership interest.

        After the Spin-off, the NOL carryforwards resulting from VoiceStream's
cumulative tax losses will remain with VoiceStream. Pursuant to a tax sharing
agreement entered into at the time of the Hutchison Investment (as defined in
note 10), VoiceStream will pay Western Wireless an amount representative of the
tax benefit of NOLs generated while VoiceStream was a wholly-owned subsidiary of
Western Wireless. This payment will not exceed $20 million, net of taxes.

10. MINORITY INTEREST IN CONSOLIDATED SUBSIDIARIES:

   
        In February 1998, Hutchison Telecommunications Limited ("HTL") and a
subsidiary of HTL (the "HTL Sub") purchased 19.9% of VoiceStream for an
aggregate purchase price of $248.4 million (the "Hutchison Investment"). Western
Wireless and VoiceStream have amended certain outstanding financing agreements
to which they are subject, and unless otherwise agreed to by HTL Sub and Western
Wireless, neither Western Wireless nor VoiceStream shall have any liability
regarding any indebtedness of the other. The HTL Sub designated two directors to
a ten person Board of Directors of VoiceStream, who have approval rights over
certain transactions of VoiceStream. If any such transaction is not approved by
the directors designated by the HTL Sub and VoiceStream implements such
transaction, HTL's only recourse is to require Western Wireless, or at Western
Wireless' option, VoiceStream to purchase such shares at fair value.   
    

        The terms of the Hutchison Investment restrict, among other things, the
transfer of assets between Western Wireless and VoiceStream as well as the
distribution of dividends or other distributions by VoiceStream.

11. SHAREHOLDERS' EQUITY:

        Stock issuances:

        In May 1998, Western Wireless completed a secondary offering on form S-3
(the "Secondary Offering") of 13,915,000 Class A Common Stock shares (including
on over-allotment exercised by the underwriters). Western Wireless did not issue
any new primary shares and received no proceeds from the Secondary Offering. The
shares were offered by certain shareholders of Western Wireless who elected to
convert a portion of their Class B Common Stock into publicly traded Class A
Common Stock for sale pursuant to a registration statement. No member of
management of Western Wireless sold any shares in the Secondary Offering.

        Western Wireless issued 100,000 shares in 1998 and 90,000 in 1997, of
its Class A Common Stock to certain key executives pursuant to an Executives
Restricted Stock Plan. The vesting of these shares are subject to certain
performance thresholds as determined by the Board of Directors. Under this same
plan, 105,000 shares were issued in January of 1999.

        In November 1997, Western Wireless issued 3,888,888 shares of its Class
A common stock (approximately 5% of the then outstanding capital stock of
Western Wireless) to a subsidiary of HTL for a purchase price of approximately
$74 million.

        In October 1997, Western Wireless issued 1,600,000 shares of its Class A
Common Stock as a portion of the consideration to purchase the cellular business
and assets of Triad (see Note 13).

        Other transactions:

        In February 1998, Western Wireless received additional paid-in capital
of approximately $123.2 million related to the Hutchison Investment. This
represents the amount in excess of the book value of VoiceStream for the 19.9%
interest purchased by the HTL Sub.

12. STOCK-BASED COMPENSATION PLANS:

        The Management Incentive Stock Option Plan (the "MISOP"), which has been
effective since 1994, provides for the issuance of up to 5,890,000 shares of
common stock as either Nonstatutory Stock Options or as Incentive Stock Options,
the terms and conditions of which are at the discretion of the administrator of
the MISOP.

12. STOCK-BASED COMPENSATION PLANS (CONTINUED):

        The Employee Stock Purchase Plan (the "ESPP"), which has been effective
since 1997, provides for the issuance of up to 1,000,000 shares of Class A
Common Stock to eligible employees participating in the plan. The terms and
conditions of eligibility under the ESPP require that an employee must have been
employed by Western Wireless or its subsidiaries for at least three months prior
to participation. A participant may contribute up to 10% of their total annual
compensation toward the ESPP, not to exceed the IRS contribution limit each
calendar year. Shares are offered under this ESPP at 85% of market value at each
offer date. Participants are fully vested at all times.

        At December 31, 1998, 1997, and 1996 Western Wireless has accounted for
the above described MISOP and ESPP following the guidelines of APB Opinion No.
25 and related interpretations. Had compensation cost for the MISOP and the ESPP
been determined based upon the fair value at the grant dates for awards under
these plans consistent with the method defined in SFAS No. 123, Western
Wireless' net loss and basic loss per share would have increased to the pro
forma amounts indicated below:

        All options outstanding at December 31, 1998, have been issued by
Western Wireless. After the Spin-off, VoiceStream intends to have its own stock
option plans that are substantially similar to the plans that are currently
administered by Western Wireless. In connection with the Spin-off, (i) Western
Wireless option holders will receive one vested VoiceStream option and one
vested Western Wireless option for each existing vested Western Wireless option
at the Spin-off; and (ii) Western Wireless option holders who become VoiceStream
employees will receive for each unvested Western Wireless option at the Spin-off
a number of unvested VoiceStream options. It is anticipated the unvested options
will have materially the same vesting schedule and expiration dates as the
original options issued by Western Wireless. Proforma disclosures required under
SFAS 123 are not presented as the number of VoiceStream options as of the
Spin-off is not yet ascertainable.

13. ACQUISITIONS:

        All of these acquisitions were accounted for using the purchase method
of accounting.

        Cellular acquisitions:

        Subsequent to December 31, 1998, Western Wireless signed an agreement to
purchase the cellular licenses and operations of the Brownsville, TX and
McAllen, TX Metropolitan Statistical Areas ("MSA") for an aggregate amount of
approximately $95.0 million in cash. This purchase is pending approval from the
FCC. Additionally, Western Wireless has purchased the cellular license and
operations of the Wyoming 4 and Oklahoma 1 Rural Service Areas ("RSA") for an
aggregate amount of approximately $19.0 million in cash. Western Wireless had
previously operated the Wyoming 4 RSA under an Interim Operating Authority
("IOA") from the FCC.

        In August 1998, Western Wireless purchased the cellular license and
operations of the Colorado 4 RSA for approximately 18.5 million in cash.

        In June 1998, Western Wireless purchased the cellular license and
operations of the Nebraska 5 RSA for approximately $15.5 million in cash. Prior
to the purchase of the Nebraska 5 RSA, Western Wireless operated this market
under an IOA from the FCC.

        In March 1998, Western Wireless was granted 52 Local Multipoint
Distribution Service ("LMDS") licenses that it was the high bidder on in an FCC
auction. Western Wireless paid approximately $14.9 million for these licenses.

13. ACQUISITIONS (CONTINUED):

        In October 1997, Western Wireless consummated the purchase of the
cellular business and assets of Triad (the "Triad Acquisition") in the RSAs
designated as Texas 1, 2, 4, and 5, Utah 3, 4 and 6, Oklahoma 7 and 8 and
Minnesota 7, 8 and 9, for an aggregate purchase price of (I) approximately
$194.5 million, plus (ii) 1,600,000 shares of Western Wireless Class A Common
Stock. In accordance with its agreement with Triad, Western Wireless filed a
shelf Registration Statement on Form S-3 covering future resales of such shares.

        During 1996 Western Wireless acquired two cellular RSAs and one cellular
MSA in the western United States. The aggregate cash paid for these transactions
was $35.6 million. Substantially all of the purchase price of each acquisition
was allocated to licensing costs.

        PCS acquisitions:

        Of the 52 LMDS licenses purchased by Western Wireless in the first
quarter of 1998, 16 were purchased on behalf of VoiceStream. VoiceStream paid
approximately $8.7 million for these licenses.

        In October 1997, as part of the Triad Acquisition, Western Wireless
purchased on behalf of VoiceStream, various D and E Block PCS licenses for an
aggregate purchase price of approximately $4.6 million.

        In June 1996, Western Wireless purchased, on behalf of VoiceStream, a
Denver MTA PCS wireless license for $66.1 million.

15. SEGMENT INFORMATION:

        Western Wireless operations are classified into two principal reportable
segments: cellular and PCS. Western Wireless provides cellular services in rural
markets and VoiceStream provides PCS services in urban markets, both in the
western United States. The type of service provided in each segment is similar,
although PCS generally offers more features. Certain centralized general and
administrative costs and assets benefit all of Western Wireless' operations.
Such centralized items include the costs of customer service and accounting
as well as the assets to support these functions. These items are allocated to
the segments in a manner which reflects the relative time devoted to each of the
segments.
