                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by, and should be read
in conjunction with, the more detailed information and the consolidated
financial statements and the notes thereto appearing elsewhere in this
Prospectus. All share and per share data in this Prospectus assumes no exercise
of the Underwriters' over-allotment options. Unless otherwise noted, references
to "Western Wireless" or the "Company" include Western Wireless Corporation and
its direct and indirect subsidiaries, including Western PCS Corporation and its
direct and indirect subsidiaries("Western PCS"). In February 1998, Western PCS
issued and sold 19.9% of its outstanding capital stock to a subsidiary of
Hutchison Telecommunications Limited. Unless the context otherwise requires,
when used herein with respect to a licensed area, "persons" and "population" are
interchangeable and refer to the aggregate number of persons located in such
licensed area, and "pops" refers to the number of such persons in a licensed
area multiplied by a company's ownership interest in the license for such
licensed area. Persons, population and pops data are estimated for 1998 based
upon 1997 estimates by Equifax Marketing Decision Systems, Inc. ("Equifax")
adjusted by the Company by applying Equifax's growth factors from 1995 to 1997
to the 1990 U.S. Census Bureau population figures, unless otherwise specified.
 
                                  THE COMPANY
 
     Western Wireless provides wireless communications services in the western
United States. The Company owns an aggregate of 199 cellular and personal
communications services ("PCS") licenses for a geographic area covering
approximately 68.0 million persons (counting only once those persons that may be
served by both cellular and PCS systems owned by the Company). In addition,
Western Wireless is a partner in ventures owning 25 PCS licenses for a
geographic area covering approximately 15.5 million persons (some of which
overlap license areas owned by the Company). Western Wireless' combined cellular
and PCS licenses, together with licenses held by the ventures in which it is a
partner, cover approximately 59% of the land in the continental United States.
In its consolidated cellular and PCS markets, the Company served 648,600
subscribers at December 31, 1997.
 
     The Company operates its cellular systems under the CELLULAR ONE brand
name. It holds 88 cellular licenses and operates cellular systems in 72 Rural
Service Areas ("RSAs") and 16 Metropolitan Statistical Areas ("MSAs") with an
aggregate population of approximately 7.3 million persons. The Company's
cellular systems cover over 95% of such population. In its consolidated cellular
markets, the Company served approximately 520,000 subscribers at December 31,
1997.
 
     The Company operates its PCS systems under its proprietary VoiceStream
brand name. Through Western PCS, the Company holds an 80.1% interest in 111
broadband PCS licenses and operates PCS systems in seven Major Trading Areas
("MTAs") -- Honolulu, Salt Lake City, El Paso/Albuquerque, Portland, Oklahoma
City, Des Moines/Quad Cities and Denver -- covering an aggregate population of
approximately 20.2 million persons. The Company obtained 96 of its broadband PCS
licenses for Basic Trading Areas ("BTAs") in the Federal Communications
Commission's ("FCC") 1997 D and E Block auctions and acquired an additional
eight PCS licenses for BTAs through an acquisition; it has not yet commenced
operations in any of such BTA markets. Cook Inlet Western Wireless PV/SS PCS,
L.P. ("Cook Inlet PCS"), a partnership in which the Company holds a 49.9%
limited partnership interest, owns broadband PCS licenses in 21 BTAs, including
seven that were acquired in the FCC's F Block auction in 1997. Cook Inlet PCS
initiated service using the VoiceStream brand name in the Tulsa, Oklahoma BTA in
June 1997. Through a joint venture, PCS service is available under the
VoiceStream brand name in the Wichita, Kansas BTA market. In its PCS markets,
the Company uses the internationally-proven Global System for Mobile
Communications ("GSM") technology as the network standard. GSM is the leading
digital wireless standard worldwide, with systems operating in approximately 109
countries, including the
 
                                        4
<PAGE>   6
 
United States, and serving over 80 million subscribers. In its consolidated PCS
markets, the Company served approximately 128,600 subscribers at December 31,
1997.
 
     Western Wireless is also engaged in activities related to its principal
wireless communications business. The Company has interests in entities which
own wireless licenses in certain foreign countries, including Ghana, Iceland and
the Republics of Latvia and Georgia. During 1997, the ventures in Latvia and
Georgia commenced operations. In addition, the Company has interests in entities
which have made wireless license applications in certain other foreign
countries. Finally, the Company operates paging systems in eight western states
and at December 31, 1997 served 31,900 paging customers.
 
STRATEGY
 
     The Company's principal focus is on the operation of wireless
communications systems in the western United States. The Company believes that
cellular is the optimum technology for rural, less densely populated areas where
it can provide service on the most cost-effective basis, and that PCS is the
optimum technology for more densely populated urban areas where analog cellular
systems are more expensive to deploy and face potential capacity constraints.
The Company's acquisition of PCS licenses has enabled it to significantly expand
both its customer base and geographic coverage and to offer enhanced wireless
communications services. The Company's focus with its PCS licenses has been, and
will continue to be, to commence operations in the most densely populated areas
within its PCS systems.
 
     The Company's operating strategy is to (i) construct and commence
operations with high quality systems and extensive coverage in rural areas with
its cellular systems and in urban areas with its PCS systems; (ii) continue to
expand its operations through increased subscriber growth and usage; (iii)
utilize its centralized management and back office functions to support the
needs of its subscribers, thereby further improving operating efficiencies and
generating greater economies of scale; and (iv) strategically acquire cellular
and PCS properties. The Company is implementing its strategy by continuing to
build its PCS systems, offering a wide range of products and services at
competitive prices, continually upgrading the quality of its network,
establishing strong brand recognition, creating a strong sales and marketing
program tailored to local markets and providing a superior level of customer
service.
 
     The Company plans to continue to take advantage of opportunities to enter
new geographic markets, including international ventures. The Company also plans
to offer services as a Competitive Local Exchange Carrier (CLEC) in select
markets.
 
CELLULAR OPERATIONS
 
     The Company operates cellular systems in 72 RSAs and 16 smaller MSAs, and
generally owns 100% of each of its cellular licenses. In such rural markets, the
Company believes that its cellular systems, which can cover large geographic
areas with relatively few cell sites, provide the optimum cost efficient
wireless service technology. In contrast, PCS technology requires more closely
located cell sites to broadcast over extended geographic areas. Accordingly, PCS
service will be less efficient and more expensive to deploy in rural markets
than cellular service, making it likely that PCS competitors will delay or avoid
entry into such markets.
 
     The Company has experienced rapid growth of its cellular operations during
the last three years. The number of the Company's cellular subscribers grew to
520,000 at December 31, 1997 from 112,800 at December 31, 1994. Service
(subscriber, roamer and other) revenues grew to $290.5 million in 1997 from
$55.6 million in 1994 and operating income from cellular operations before
interest, taxes and depreciation and amortization increased to $103.9 million in
1997 from $2.1 million in 1994. The Company believes these results reflect the
strong demand for wireless services in its markets, the success of its marketing
strategy and its management capabilities. See

"Risk Factors," "Selected Consolidated Financial Data" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
     The Company believes based upon its experience that several attributes of
RSAs and small MSAs make such markets inherently 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 and less
competition.
 
     The Company 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 and no-answer transfer.
The Company provides extended regional and national service to cellular
subscribers in its markets, through its membership in North American Cellular
Network ("NACN"), 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.
 
     The Company has roaming arrangements with virtually every cellular carrier
in North America. The Company also has roaming arrangements with certain
cellular carriers in areas adjacent to the Company's markets that provide the
Company's customers attractive rates when roaming in these surrounding areas. In
addition, the Company has roaming arrangements with several PCS service
providers, including Sprint Spectrum L.P. ("Sprint Spectrum"), AT&T Wireless
Services, Inc. ("AT&T Wireless"), AirTouch Cellular Communications, Inc.
("AirTouch"), Southwestern Bell Mobile Systems ("Southwestern Bell") and PCS
PrimeCo. L.P. ("PrimeCo."), that allow their customers to roam in the Company's
cellular markets with dual-mode handsets.
 
PCS OPERATIONS
 
     Through Western PCS, the Company holds an 80.1% interest in 111 PCS
licenses, covering approximately 64.2 million persons. The Company operates PCS
systems in the Honolulu, Salt Lake City, El Paso/Albuquerque, Portland, Oklahoma
City, Des Moines/Quad Cities and Denver MTAs, and is constructing the initial
phase of its PCS systems in the Seattle-Tacoma, Phoenix and Tucson BTAs. The
Company has not yet finalized its construction plans for all of the licenses
purchased in the D and E Block auctions. Cook Inlet PCS provides service in the
Tulsa, Oklahoma BTA utilizing the VoiceStream brand name, and is in the planning
stage of developing a PCS system in the Spokane BTA. Through joint ventures, PCS
services are offered or will be offered under the VoiceStream brand name in the
Wichita, Kansas BTA with Omnipoint Corp. and certain BTAs in Iowa with Iowa
Network Services.
 
     The Company has experienced rapid growth of its PCS operations since
inception in February 1996. During such period, the number of the Company's PCS
subscribers grew to 128,600 at December 31, 1997 and service (subscriber, roamer
and other) revenues grew to $52.6 million for 1997. The Company believes these
results reflect the strong demand for wireless services in its markets, the
success of its marketing strategy and its management capabilities. See "Risk
Factors," "Selected Consolidated Financial Data" and "Management's Discussion
and Analysis of Financial Condition and Results of Operations."
 
     The Company believes its PCS service offerings are broader than those
generally offered by cellular systems in the Company's PCS markets. PCS 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.
 
     The Company's goal is to achieve significant market penetration by
aggressively marketing competitively priced PCS services under its proprietary
VoiceStream brand name, offering enhanced services not generally provided by
cellular operators and providing superior customer service. In
 
                                        6
<PAGE>   8
 
addition, the Company is well-positioned to be a low-cost provider of PCS
services by taking advantage of the existing business infrastructure, including
centralized management, marketing, billing and customer service functions, and
by focusing on efficient customer acquisition and retention.
 
     The Company's experience is that PCS technology is better suited to urban
areas than rural areas and has cost advantages relative to cellular technology
in urban areas. PCS cell sites operate at a higher frequency and lower power
than cellular cell sites and, therefore, typically have a smaller coverage area.
Unlike rural areas, wireless systems in urban areas require substantial
frequency "reuse" to provide high capacity. The coverage advantage that cellular
frequencies and analog technology enjoy in rural areas is not present in urban
areas because analog cellular technology does not provide efficient frequency
reuse. As a result, the higher frequency, lower power, digital PCS systems are
likely to provide greater capacity in urban areas.
 
     The Company selected GSM as the digital standard for its PCS system because
the Company believes it has significant advantages over the other competing
digital standards, including the experience of years of proven operability in
Europe and Asia, enhanced features and an open system architecture that will
allow the Company to choose from a variety of equipment options and providers.
GSM is the leading digital wireless standard in the world, with over 80 million
customers in 109 countries.
 
     The Company has entered into roaming agreements with substantially all of
the licensees that have chosen to deploy the GSM standard in their PCS markets
in the United States which will provide for roaming by the Company's PCS
subscribers into these carriers' PCS markets, and vice versa, when such systems
are operational. The Company also has over 70 reciprocal roaming agreements with
a variety of international carriers who have chosen to deploy the GSM standard.
 
RECENT DEVELOPMENTS; INVESTMENT IN WESTERN PCS
 
     In October 1997, the Company entered into an agreement with Hutchison
Telecommunications Limited ("HTL") and a subsidiary of HTL pursuant to which the
HTL subsidiary agreed to purchase approximately 5.1% of the outstanding Common
Stock of the Company for a purchase price of $74.3 million. This transaction
closed in November 1997. The proceeds from the sale of the Common Stock were
used to reduce amounts outstanding under the Company's revolving credit
facility.
 
     The Company and Western PCS also entered into an agreement with HTL and
another HTL subsidiary pursuant to which the HTL subsidiary purchased, in
February 1998, newly issued shares of stock of Western PCS constituting 19.9% of
the outstanding capital stock of Western PCS for an aggregate purchase price of
$248.4 million (the "HTL Investment"). Western PCS is the Company's subsidiary
that holds substantially all of the Company's PCS assets. Until the sale of
stock to the subsidiary of HTL, Western PCS had been a 100% owned subsidiary of
the Company. Approximately $135 million of the net proceeds will be used by
Western PCS for the continued build-out of its PCS systems during 1998. The
remainder of the proceeds was paid to the Company as a repayment of advances
made to Western PCS and was used by the Company, in turn, to reduce amounts
outstanding under its revolving credit facility.
 
     Western Wireless is a Washington corporation. Its principal executive
offices are located at 2001 NW Sammamish Road, Issaquah, Washington, 98027, and
its telephone number is (425) 313-5200.

                                  RISK FACTORS
 
     In addition to the other information contained in this Prospectus, the
following should be considered carefully in evaluating the Company and its
business before investing in the Class A Common Stock.
 
HIGH LEVERAGE; DEBT SERVICE; RESTRICTIVE COVENANTS
 
     The Company is, and will continue to be, highly leveraged and subject to
significant financial restrictions and limitations. As of December 31, 1997, the
Company's total indebtedness was $1,395 million or approximately 87.8% of its
total capitalization, and consisted of indebtedness under the Company's credit
facility (the "Credit Facility") with a consortium of lenders providing for $750
million of revolving credit and a $200 million term loan, indebtedness of a
subsidiary of Western PCS under a $300 million credit facility (the "PCS Vendor
Facility" and, together with the Credit Facility, the "Senior Secured
Facilities") and $200 million principal amount of senior subordinated notes due
2006 (the "2006 Notes") and $200 million principal amount of senior subordinated
notes due 2007 (the "2007 Notes"). Substantially all the assets of the Company,
other than the PCS licenses acquired in the FCC's D and E auctions, certain
licenses acquired in the FCC's A and B auctions and certain other assets, are
pledged as security under the Senior Secured Facilities, including the shares of
Western PCS held by the Company.
 
     For the year ended December 31, 1997, the Company had a negative ratio of
earnings to fixed charges and earnings coverage deficiency of approximately
$269.5 million. There can be no assurance that the Company will generate
sufficient cash flow from operating activities to meet its debt service and
working capital requirements. In such event, the Company may need to seek
additional financing. There can be no assurance that any such financing or
refinancing could be obtained on terms that are acceptable to the Company. In
the absence of such financing or refinancing, the Company could be materially
limited in its ability to build out PCS systems in its BTAs or be forced to
dispose of assets in order to make up for any shortfall in the payments due on
its indebtedness under circumstances that might not be favorable to the
realization of the highest price for such assets. Given that a substantial
portion of the Company's assets consists of intangible assets, principally
licenses granted by the FCC, the value of which will depend upon a variety of
factors (including the success of the Company's PCS and cellular businesses and
the wireless communications industry in general), there can be no assurance that
the Company's assets could be sold quickly enough, or for sufficient amounts, to
enable the Company to meet its obligations.
 
     During 1998, the Company anticipates spending approximately $275 million to
complete construction of the build-out of the Seattle-Tacoma, Phoenix and Tucson
BTA systems, to provide funds to Cook Inlet PCS for the build-out of certain BTA
markets and to expand the build-out of the Company's PCS MTA systems. The
Company will utilize $135 million of the net proceeds of the HTL Investment,
other cash on hand, amounts available for borrowing under the Credit Facility,
and, if available, other sources of funding, for such purposes. At December 31,
1997, the amount available for borrowings under the Credit Facility was $239
million and the total unused portion of the Credit Facility was $255 million,
only a portion of which is permitted to be utilized in connection with the
Company's PCS systems. In addition, further funds (which may be significant)
will be required to finance the continued growth of PCS operations, provide for
working capital and service debt. The Company continues to consider and expects
to pursue additional sources of funding to further development of the PCS
business. Such sources may include the issuance of additional indebtedness
and/or the sale of additional equity at the parent or a subsidiary level. To the
extent that the build-out of the PCS systems is faster than expected, the costs
are greater than anticipated or the Company takes advantage of acquisition
opportunities, including those that may arise through the reauction of BTAs by
the FCC, the Company may require additional funding to implement its business
strategy. There can be no assurance that the Company will be able to obtain such
financing on acceptable or favorable terms and in adequate amounts to accomplish
its objectives.
                                       11
<PAGE>   13
 
     The Senior Secured Facilities, the indenture under which the 2006 Notes
were issued (the "2006 Notes Indenture") and the indenture under which the 2007
Notes were issued (the "2007 Notes Indenture") contain, and any additional
financing agreements may contain, certain restrictive covenants. The Senior
Secured Facilities, the 2006 Notes Indenture and the 2007 Notes Indenture
require the Company to comply with certain financial and operational performance
covenants, and, while the Company expects to remain in compliance with such
covenants, there can be no assurance to that effect. The restrictions contained
in the Senior Secured Facilities, the 2006 Notes Indenture and the 2007 Notes
Indenture affect, and in some cases will significantly limit or prohibit, among
other things, the ability of the Company to incur indebtedness, make prepayments
of certain indebtedness, pay dividends, make investments, create liens, sell
assets and engage in mergers and consolidations. In addition to such covenants,
the Senior Secured Facilities require the Company or a subsidiary of Western
PCS, as the case may be, to maintain certain financial ratios, including, among
others, a limitation on the incurrence of indebtedness based on the ratio of the
Company's indebtedness to operating cash flow (as defined in the Credit
Facility), a requirement that the Company's ratio of operating cash flow to cash
interest expense be not less than specified levels, and covenants of a
subsidiary of Western PCS relating to minimum gross revenues and the ratio of
cash coverage to operating cash flow (as such terms are defined in the PCS
Vendor Facility). An event of default under the Senior Secured Facilities, the
2006 Notes Indenture or the 2007 Notes Indenture would allow the acceleration of
the maturities of the indebtedness thereunder. In such event, it is likely that
all of the Company's indebtedness would become immediately due and payable.
 
PAST AND FUTURE OPERATING LOSSES AND NEGATIVE CASH FLOW
 
     The Company sustained operating losses of approximately $159.7 million
(including $196.9 million of losses attributable to the Company's PCS
operations), $86.9 million (including $81.8 million of losses attributable to
the Company's PCS operations) and $23.9 million (including $3.7 million of
losses attributable to the Company's PCS operations) for the years ended
December 31, 1997, 1996 and 1995, respectively. At December 31, 1997, the
Company had a deficit of $479.8 million. The Company expects to incur
significant operating losses and to generate negative cash flow from operating
activities during the next several years, while it develops and constructs its
PCS systems and continues to build a PCS subscriber base. There can be no
assurance that the Company will achieve or sustain profitability or positive
cash flow from operating activities in the future or that it will generate
sufficient cash flow to service its debt requirements. See "-- High Leverage;
Debt Service; Restrictive Covenants."
 
COMPETITION
 
     Competition for subscribers among wireless licensees is based principally
upon the services and enhancements offered, the technical quality of the system,
customer service, system coverage, capacity and price. The Company currently
faces and expects to face increased competition from entities providing similar
services using other communications technologies and services. While some of
these technologies and services are currently operational, others are being
developed or may be developed in the future. The Company's PCS business in
markets in which it operates faces competition from providers of cellular
service and from other providers of PCS services as they enter such markets.
Under current FCC rules, there may be up to six PCS licenses granted in each
geographic area in addition to the two existing cellular licenses. The Company
has one cellular competitor in each of its cellular markets, including AirTouch,
Aliant Communications, Inc. ("Aliant"), CommNet Cellular, Inc. ("CommNet"),
Kansas Cellular, Southwestern Bell and United States Cellular Corporation ("US
Cellular"), and there are or will be up to six PCS licensees in each of its
markets. The Company's principal competitors in its PCS business are Sprint
Spectrum, PrimeCo. and AT&T Wireless Services, as well as the two existing
cellular providers in its PCS markets. These cellular competitors include AT&T
Wireless, US Cellular and AirTouch. The Company also competes with paging,
dispatch and conventional mobile telephone companies, resellers
                                       12
<PAGE>   14
 
and landline telephone service providers. Competition in the markets in which
the Company competes is intense. Given the rapid advances in the wireless
communications industry, there can be no assurance that new technologies will
not evolve that will compete with the Company's products and services. In
addition, a number of the Company's competitors may have substantially greater
financial, technical, marketing, sales, manufacturing and distribution resources
than those of the Company and have significantly greater experience than the
Company in testing new or improved communications products and services and
obtaining regulatory approvals. Some competitors are expected to market other
services, such as landline telephone and cable services, with their wireless
communications service offerings. Several of the Company's competitors are
operating, or planning to operate, through joint ventures and affiliation
arrangements, wireless communications systems that encompass most of the
continental United States. Also, the FCC has licensed Specialized Mobile Radio
("SMR") dispatch system operators to construct digital mobile communications
systems on existing SMR frequencies, referred to as Enhanced Specialized Mobile
Radio ("ESMR"), in many cities throughout the United States, including some of
the markets in which the Company operates. ESMR systems, including those
operated by Nextel Communications, Inc. ("Nextel"), are competitive with the
Company's cellular and PCS systems. See "-- Risks Relating to GSM Technical
Standard."
 
PCS BUILD-OUT AND CAPITAL EXPENDITURES
 
     Through Western PCS, the Company currently operates PCS systems in the
Honolulu, Salt Lake City, El Paso/Albuquerque, Portland, Oklahoma City, Des
Moines/Quad Cities and Denver MTAs. The Company's 30 MHz PCS licenses are
subject to a requirement that the Company construct network facilities that
offer coverage to at least one-third of the population in the relevant MTA by
June 2000, five years from the grant of the license, and to at least two-thirds
of the population by June 2005, 10 years from the grant of the license (the
"10-Year Build-out Requirement"). The Company anticipates that its build-out in
all of its MTA markets, if completed as currently planned by the end of 1998,
will satisfy the 10-Year Build-out Requirement. The Company's 10 MHz PCS
licenses are subject to a requirement that the Company construct network
facilities that offer coverage to at least one-quarter of the population in
their relevant BTA within five years from the grant of the license, or make a
showing of substantial service in their relevant BTA within five years from the
grant of the license. Should the Company fail to meet these coverage
requirements, it may be subject to forfeiture or nonrenewal of the license or
the imposition of fines by the FCC. The build-out of PCS systems in the
Company's BTAs will require substantial additional capital, which may include
the issuance of equity or debt by Western PCS or its subsidiaries. The PCS
build-out in each of its PCS markets is subject to successful completion of the
network design, site and facility acquisitions, the purchase and installation of
the network equipment, network testing and satisfactory accommodation of
microwave users currently using the spectrum. Delays in any of these areas could
have a material adverse effect on the Company's ability to complete the
build-out in a timely manner.
 
     The successful build-out of additional PCS systems by the Company will
depend to a significant degree upon the Company's ability to lease or acquire
appropriate sites for the location of its base station equipment. The Company
has begun the site selection and acquisition process for certain additional PCS
systems. The site selection process will require the continued successful
negotiation of use agreements for or acquisitions of numerous additional sites,
and may require the Company to obtain zoning variances or other governmental or
local regulatory approvals, which are beyond the Company's control. Delays in
the site selection process, as well as construction delays and other factors,
could adversely affect the timing of the commencement of commercial service in
such additional PCS systems.
 
     During 1998, the Company anticipates spending approximately $275 million to
complete the build-out of the Seattle-Tacoma, Phoenix and Tucson BTA systems, to
provide funds to Cook Inlet PCS for the build-out of its PCS systems and to
expand the build-out of the Company's PCS MTA
 
                                       13
<PAGE>   15
 
systems. The Company will utilize $135 million of the net proceeds of the HTL
Investment, other cash on hand, amounts available for borrowing under the Credit
Facility, and, if available, other sources of funding, for such purposes. In
addition, further funds (which may be significant) will be required to finance
the continued growth of its PCS operations, including the build-out of its BTAs,
provide for working capital and service debt. The build-out of additional PCS
systems by the Company will require substantial additional funds (including
borrowing at the Western PCS level) and the capital cost of completing the
project in any particular MTA or BTA and overall could vary materially from
current estimates. If adequate funds are not available from its existing capital
resources, the Company may be required to curtail its service operations or to
obtain additional funds on terms less favorable than those contained in the
Company's current arrangements.
 
     In addition, the implementation of the PCS build-out plan is subject to the
availability from suppliers of the infrastructure equipment and subscriber
equipment the Company plans to use. Accordingly, there are risks associated with
the completion of development, timely manufacture and successful implementation
of newly developed wireless equipment in the build-out of the Company's PCS
systems. The Company has entered into agreements for the supply of
infrastructure equipment with Northern Telecom Inc. ("NORTEL"), Nokia
Telecommunications Inc. (together with its affiliate, Nokia Mobile Phones, Inc.,
"Nokia") and Lucent Technologies Inc. ("Lucent Technologies").
 
DEPENDENCE UPON KEY PERSONNEL
 
     The Company is dependent to a large degree on the services of Mr. Stanton,
as Chairman of the Board and Chief Executive Officer, and other current members
of management. The Company and Mr. Stanton have entered into an employment
agreement which provides that Mr. Stanton's employment may be terminated at any
time by the Company. Loss of the services of Mr. Stanton or other members of
management could have a material adverse effect on the business of the Company
and qualified replacements may be difficult or impossible to find or retain. An
event of default under the Credit Facility would occur if Mr. Stanton (or a
suitable replacement) ceases, for any reason, to be the Chairman of the
Company's Board of Directors.
 
RISKS RELATING TO GSM TECHNICAL STANDARD
 
     When the FCC first licensed cellular systems in the United States, it
specified the technical standards of analog cellular system operation to ensure
nationwide compatibility between all analog cellular carriers. In contrast, the
FCC has not mandated the technology standard for digital cellular or PCS
operations, leaving each licensee free to select among several competing
technologies that have sufficient technological differences to preclude their
interoperability. The Company has deployed the GSM technical standard in its PCS
markets and believes that GSM offers the Company significant advantages over the
other competing technologies. There are, however, certain risks with respect to
the deployment of GSM.
 
     The Company, together with the other MTA and BTA PCS licensees who deploy
or who have announced their intent to deploy GSM-based systems, collectively
will cover markets containing approximately 260 million persons, representing
approximately 98% of the U.S. population (based on 1990 U.S. Census Bureau
figures used by the FCC for auction purposes) (including one licensee currently
in bankruptcy). In order for the Company's PCS subscribers to roam in other
markets, and vice versa, at least one PCS licensee in the other market must
utilize the GSM standard, or the subscribers must use dual-mode handsets that
permit the subscriber to use the cellular system in the other market. Dual-mode
GSM handsets which permit such usage, while currently commercially available
from Nokia, may not be available in adequate supply until the third quarter of
1998 and are more expensive than single-mode handsets. The lack of
interoperability, the comparatively higher cost or the potential lack of
consumer acceptance of such handsets may impede the Company's ability to retain
current cellular subscribers or attract potential new wireless communications
subscribers. There can be no assurance that PCS licensees who have announced
their intent to
                                       14
<PAGE>   16
 
deploy GSM-based systems will build out their respective markets, and,
accordingly, GSM-based systems may cover less than 98% of the U.S. population.
 
     The Company's principal PCS competitors have committed to standards other
than GSM. As a result, without adequate supplies of PCS handsets that can access
both GSM and competing systems, there is a risk that customers of the Company's
PCS services may not be able to conveniently use PCS services while roaming in
certain geographic areas outside the Company's PCS markets. PrimeCo and Sprint
Spectrum have deployed PCS systems based on a Code Division Multiple Access
("CDMA") standard. AT&T Wireless and Southwestern Bell have deployed systems
based on the Time Division Multiple Access ("TDMA") standard. It is estimated
that together, CDMA-based PCS providers, including competitors in several of the
Company's markets, own licenses covering approximately 100% of the U.S.
population (based on 1990 U.S. Census Bureau figures used by the FCC for auction
purposes) and AT&T Wireless and Southwestern Bell, with their TDMA standard, own
PCS licenses which cover approximately 94% of the U.S. population (based on 1990
U.S. Census Bureau figures used by the FCC for auction purposes). Licensees in
the FCC's completed C, D, E & F Block auctions of PCS licenses may or may not
select GSM technology; certain purchasers of licenses in such auctions have
announced their intention not to utilize the GSM standard in such markets.
Accordingly, certain major metropolitan areas may not be served by GSM-based PCS
systems, or there may be delays in deployment of GSM-based PCS systems in some
markets. The Company's ability to continue to build a PCS subscriber base and to
compete successfully in the PCS business with those operators offering greater
roaming capabilities may be adversely affected by the fact that the Company's
PCS subscribers will only be able to roam into regions served by GSM-based PCS
systems until dual-mode handsets permitting them to use the existing cellular
system become widely-available.
 
GOVERNMENTAL REGULATION
 
     The licensing, construction, operation, acquisition and sale of cellular
and PCS systems, as well as the number of cellular and other wireless licensees
permitted in each market, are regulated by the FCC. Changes in the regulation of
such activities, such as a decision by the FCC to issue new licenses or permit
more than two licenses in each market for cellular communications services,
could have a material adverse effect on the Company's operations. The FCC has
recently completed an auction of spectrum in other frequency bands which could
potentially be used for wireless communications. In addition, all cellular
licenses in the United States, including the Company's licenses, were granted
for an initial 10-year term and are subject to renewal. Licenses may be revoked
by the FCC at any time for cause. The Company has approximately 35 cellular
licenses which will be subject to renewal in the next three years. While the
Company believes that each of its cellular licenses will be renewed based upon
FCC rules establishing a presumption in favor of licensees that have provided
"substantial" service during their past license term and have substantially
complied with their regulatory obligations during the past license period, there
can be no assurance that all of the Company's cellular licenses will be renewed.
 
     All PCS licenses are granted for a 10-year period, at the end of which
period the licensee must apply for renewal. Licenses may be revoked by the FCC
at any time for cause. All 30 MHz broadband PCS licenses, including those of the
Company, are subject to the 10-Year Build-out Requirement. While the Company
believes that each of its PCS licenses will be renewed based upon FCC rules
establishing a presumption in favor of licensees that have provided
"substantial" service during the past license term and have substantially
complied with their regulatory obligations during the past license period, there
can be no assurance that all of the Company's PCS licenses will be so renewed.
See "-- PCS Build-out and Capital Expenditures."
 
     The Company must also obtain a number of approvals, licenses and permits in
the operation of its business, including authorizations from the Federal
Aviation Administration (the "FAA") in connection with cellular and PCS towers.
Additionally, the wireless communications industry is subject to certain state
and local governmental regulation. Operating costs are also affected by
                                       15
<PAGE>   17
 
other governmental actions that are beyond the Company's control. There is no
assurance that the various federal, state and local agencies responsible for
granting such licenses, approvals and permits will do so or that, once granted,
will not revoke or fail to renew them. The absence of such licenses, approvals
and permits would adversely affect existing operations and could delay
commencement of or prohibit certain business operations proposed by the Company.
 
     Because the Company has controlling interests in cellular markets that
overlap the Denver MTA and the Oklahoma City MTA, the Company must comply with
FCC rules that limit the aggregate amount of cellular and PCS spectrum that a
single entity may own or control in a given territory. Current rules would
require divestiture of certain cellular or PCS holdings. However, pending
administrative challenges may result in additional compliance options.
 
     The wireless communications industry also is subject to continually
evolving regulation. There are a number of issues on which modification to
existing regulation or new regulation has been or in the future may be
suggested, including the effect of wireless communications equipment on medical
equipment and devices, electromagnetic interference and cancer, as well as
interference between types of wireless systems. As new regulations are
promulgated on these subjects or other subjects, the Company may be required to
modify its business plans or operations in order to comply with any such
regulations. There can be no assurance that the Company will be able to do so in
a cost effective manner, if at all. See "-- Radio Frequency Emission Concerns;
Medical Device Interference."
 
HOLDING COMPANY STRUCTURE
 
     Substantially all of the Company's assets and operations are held by or
conducted through subsidiaries and, to that extent, the Company is effectively a
holding company. The Company relies on dividends, loan repayments and other
intercompany cash flows from its subsidiaries to generate the funds necessary to
meet its debt service obligations. The payment of dividends and the making and
repayment of loans and advances by the Company to its subsidiaries are subject
to statutory, contractual and other restrictions, are dependent upon the
earnings of such subsidiaries and are subject to various business
considerations. In addition, as a result of the HTL Investment, the Company will
be entitled to receive only 80.1% of dividends declared and other economic or
tax benefits realized by Western PCS, if any. Moreover, claims of creditors of
the Company's subsidiaries, including tax authorities and trade creditors, will
generally have a priority claim to the assets of such subsidiaries over the
claims of the Company and the holders of indebtedness of the Company.
 
INTELLECTUAL PROPERTY AND BRANDING
 
     The Company currently uses the registered service mark CELLULAR ONE to
market its cellular services. The Company's use of this service mark is governed
by five-year contracts between the Company and Cellular One Group, the owner of
the service mark. Each of these agreements may be renewed at the Company's
option for two additional five-year terms so long as the Company meets operating
and service quality standards for its cellular service areas. If these
agreements were not renewed upon expiration or if the Company were to fail to
meet the applicable operating or service quality standards, and, therefore, were
no longer permitted to use the CELLULAR ONE service mark, the Company's ability
to attract new subscribers and to retain existing subscribers could be
materially impaired. In addition, if for some reason beyond the Company's
control the name CELLULAR ONE were to suffer diminished marketing appeal, the
Company's ability both to attract new subscribers and retain existing
subscribers could be materially impaired. In such circumstances or otherwise,
the Company may explore development or acquisition of a new service mark.
 
     The Company currently uses its VoiceStream registered service mark to
market its PCS services in all of its operational PCS markets. There can be no
assurance that such registration will provide any meaningful benefit to the
Company. Competitors of the Company possess, and others
 
                                       16
<PAGE>   18
 
may develop over time, branding with significantly greater name recognition than
that of the Company. A failure by the Company to maintain existing rights to its
current cellular branding, to develop value in its VoiceStream mark or to
develop suitable alternatives thereto would have a material adverse effect on
the Company's ability to market its products and services and could require the
Company to invest significant additional funds to develop such alternatives.
 
RADIO FREQUENCY EMISSION CONCERNS; MEDICAL DEVICE INTERFERENCE
 
     Media reports have suggested that certain radio frequency ("RF") emissions
from wireless handsets may be linked to various health concerns, including
cancer, and may interfere with various electronic medical devices, including
hearing aids and pacemakers. Concerns over RF emissions may have the effect of
discouraging the use of wireless handsets, which could have an adverse effect
upon the Company's business. On August 25, 1997, the FCC further updated the
guidelines and methods it uses for evaluating RF emissions from radio equipment,
including wireless handsets. While the update imposes more restrictive standards
on RF emissions from lower power devices such as wireless handsets, the Company
believes that all wireless handsets currently marketed by the Company and in use
by the Company's subscribers already comply with the new standards.
 
     Certain interest groups have requested that the FCC investigate claims that
the GSM technology poses health concerns and causes interference with hearing
aids and other medical devices. The Center for the Study of Electromagnetic
Compatibility at the University of Oklahoma, which was founded in 1994 with
funds from the wireless industry, is studying this issue and in 1996 released
its findings with respect to the first phase of its study. Such phase of the
study, which was designed to examine extreme conditions, found that digital
technologies cause interference with hearing aids in certain instances. In
addition, the Personal Communications Industry Association ("PCIA") announced in
July 1995 that it was undertaking an industry-wide study to gather information
on possible PCS interference with medical devices for all PCS standards. There
can be no assurance that the findings of such studies will not have an adverse
effect on the Company's business (including its use of GSM technology) or that
such findings will not lead to governmental regulations that will have an
adverse effect on the Company's business.
 
FINALITY OF PCS AUCTIONS
 
     All of the MTA PCS licenses, including those of the Company, and most of
the BTA PCS licenses auctioned under the C, D, E and F Blocks, have been awarded
by the FCC and the holders of the licenses are permitted to construct their PCS
systems and commence operations. The Orders granting the Company and Cook Inlet
PCS their respective PCS licenses are final and non-appealable. Nevertheless,
there are certain unresolved actions before the FCC following remand by a
federal court challenging the validity of certain spectrum aggregation limits
which affected eligibility for the auction. As a result of the challenges,
although it currently appears unlikely, the Company could lose its PCS licenses
or have adverse conditions imposed on them which could have a material adverse
effect on the Company.
 
CONTROL BY MANAGEMENT AND EXISTING SHAREHOLDERS; ANTI-TAKEOVER EFFECT OF DUAL
CLASSES OF COMMON STOCK; CERTAIN CHARTER PROVISIONS AND WASHINGTON LAW
 
     Holders of Class A Common Stock are entitled to one vote per share and
holders of Class B Common Stock are entitled to ten votes per share. Each share
of Class B Common Stock is convertible at any time into one share of Class A
Common Stock. As of March 31, 1998, certain officers of the Company and certain
other holders of shares of Class B Common Stock (including certain Selling
Shareholders) who are parties to an agreement dated May 1996 (the "Voting
Agreement"), beneficially owned 262,174 shares of outstanding Class A Common
Stock and 48,432,853 shares of outstanding Class B Common Stock, which
represented approximately 64.2% of the outstanding shares of Common Stock and
87.7% of the combined voting power of the Common Stock. Of such shares of Class
B Common Stock, 11,000,000 shares will be converted into
                                       17
<PAGE>   19
 
the shares of Class A Common Stock sold in the Offerings. These shareholders
have agreed to vote their shares for each other's designees, subject to certain
ownership requirements, and are able to control the election of the entire Board
of Directors. Such voting control by such holders of Common Stock, and certain
provisions of Washington law affecting acquisitions and business combinations,
which have been incorporated by the Company into its Articles of Incorporation,
may discourage certain transactions involving an actual or potential change of
control of the Company, including transactions in which the holders of Class A
Common Stock might receive a premium for their shares over the then-prevailing
market price, and may have a depressive effect on the market price for Class A
Common Stock.
 
SEASONALITY
 
     The Company, and the wireless communications industry in general, have
historically experienced significant subscriber growth during the fourth
calendar quarter. Accordingly, during such quarter the Company experiences
greater losses on equipment sales and increases in sales and marketing expenses.
The Company has historically experienced highest usage and revenue per
subscriber during the summer months. The Company expects these trends to
continue.
 
POSSIBLE VOLATILITY OF PRICE OF CLASS A COMMON STOCK
 
     The market price of the Class A Common Stock may be extremely volatile.
Factors such as fluctuations in the valuation of wireless licenses, results of
future FCC auctions, acquisitions by the Company, significant announcements by
the Company and its competitors, quarterly fluctuations in the Company's
operating results and general conditions in the communications market may have a
significant impact on the market price of the Class A Common Stock. In addition,
in recent years the stock market has experienced extreme price and volume
fluctuations. These fluctuations have had a substantial effect on the market
prices for many high technology and communications companies, often unrelated to
the operating performance of the specific companies.
 
SHARES ELIGIBLE FOR FUTURE SALE
 
     Sales of substantial amounts of Class A Common Stock in the public market
could adversely affect prevailing market prices. Shares sold in the public
offerings of Class A Common Stock are freely tradable in the public market.
Shares of Class B Common Stock are convertible at any time into shares of Class
A Common Stock on a one-for-one basis and such shares generally convert
automatically into Class A Common Stock upon a transfer. In addition to the
22,871,401 outstanding shares of Class A Common Stock as of March 31, 1998,
41,946,762 additional outstanding shares of Class A Common Stock (assuming the
conversion of Class B Common Stock into Class A Common Stock on a one-for-one
basis) were eligible for sale in the public market (excluding the shares to be
sold by the Selling Shareholders in the Offerings). Also, up to an aggregate of
4,611,134 shares of Class A Common Stock issuable upon exercise of outstanding
stock options ("Option Shares"), and up to an aggregate of 1,000,000 shares of
Class A Common Stock purchased under the Company's Employee Stock Purchase Plan,
have been registered by the Company and are eligible for resale in the public
market at various times, depending upon when such shares are actually issued, if
at all. The Company is party to additional agreements and management incentive
plans which obligate it to issue additional shares of Class A Common Stock which
may become eligible for resale in the public market at various times. The
Company has registered all of the Option Shares and the shares issuable under
the Employee Stock Purchase Plan for resale in the public market. As of March
31, 1998 options with respect to 2,324,559 of the Option Shares were
exercisable, and 581,246 additional shares of Class A Common Stock were reserved
for issuance pursuant to future option grants under the Company's stock option
plan. The Company, the Selling Shareholders, the Company's executive officers
and directors and certain other shareholders of the Company have agreed during
the period beginning from the date of this Prospectus and continuing to and
including the date 90 days after the date of this Prospectus, subject to certain
exceptions, not to offer, sell,

substantially similar to the shares of Class A Common Stock or which are
convertible or exchangeable into securities which are substantially similar to
the shares of Class A Common Stock.

                      SELECTED CONSOLIDATED FINANCIAL DATA
 
     The following table sets forth certain selected consolidated financial and
operating data for the Company as of and for each of the five years in the
period ended December 31, 1997, which was derived from the Company's
consolidated financial statements and notes thereto that have been audited by
Arthur Andersen LLP, independent public accountants. All of the data should be
read in conjunction with "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and the Company's consolidated financial
statements and notes thereto. The Company 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 the Company 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.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
 
     The following is a discussion and analysis of the consolidated financial
condition and results of operations of the Company and should be read in
conjunction with the Company's consolidated financial statements and notes
thereto and other financial information included herein. As a result of
acquisitions, the Company's operating results for prior periods may not be
indicative of future performance.
 
OVERVIEW
 
     The Company provides wireless communications services in the western United
States through the ownership and operation of cellular communications systems in
88 RSAs and MSAs including 12 RSAs acquired from Triad Cellular Corporation,
Triad Cellular L.P. and certain of their affiliates (collectively "Triad") in
October 1997. The Company owns broadband PCS licenses in seven MTAs, each of
which has commenced commercial operations. During 1997, the Company was granted
100 additional PCS licenses in the FCC's D and E Block auctions and acquired
eight PCS licenses as part of its acquisition of Triad in October 1997. Cook
Inlet PCS, a partnership in which the Company holds a 49.9% limited partnership
interest, owns broadband PCS licenses in 21 BTAs including seven that were
acquired in the FCC F Block auction during the first quarter of 1997. The first
of these BTAs commenced commercial operations in June 1997.
 
     The Company's revenues consist primarily of subscriber revenues (including
access charges and usage charges), roamer revenues (fees charged for providing
services to subscribers of other cellular and PCS communications systems when
such subscribers, or "roamers," place or receive a phone call within one of the
Company's service areas) and equipment sales. The majority of the Company's
revenues are derived from subscriber revenues. The Company had no revenues from
its paging or PCS systems prior to February 1, 1996, and February 29, 1996,
respectively. Revenues from paging systems are included in other revenue. The
Company expects to continue to sell cellular and PCS 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 revenues.
 
     Cost of service consists of the cost of providing wireless service to
subscribers, primarily including costs to access local exchange and long
distance carrier facilities and maintain the Company's wireless network. General
and administrative expenses include the costs associated with billing a
subscriber and the administrative cost 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 sales offices and retail locations,
advertising and promotional expenses. Depreciation and amortization includes
primarily depreciation expense associated with the Company's 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 the
Company's operations. 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.
 
     As used herein, "EBITDA" represents operating income (loss) before
depreciation and amortization. EBITDA is a measure commonly used in the industry
and should not be construed as an alternative to operating income (loss) (as
determined in accordance with GAAP), as an alternative to cash flows from
operating activities (as determined in accordance with GAAP), or as a measure of
liquidity. Cellular EBITDA represents EBITDA from the Company's cellular
operations and PCS EBITDA represents EBITDA from the Company's PCS operations.
 
                                       24
<PAGE>   26
 
     In the comparisons that follow, the Company has separately set forth
certain information relating to cellular operations (including paging) and PCS
operations. The Company believes that this is appropriate because its cellular
systems have been operating for a number of years and operate in rural markets
while its PCS systems did not commence operations until 1996 and operate in
urban markets.
 
RESULTS OF OPERATIONS FOR THE YEARS ENDED DECEMBER 31, 1997, 1996 AND 1995
 
  CELLULAR OPERATIONS
 
     The Company had 520,000 cellular subscribers at December 31, 1997,
representing an increase of 195,800 or 60.4% during 1997. At December 31, 1996
and 1995, the Company had 324,200 and 209,500 cellular subscribers,
respectively, representing an increase of 54.7% during 1996 and 85.7% during
1995. In 1997, 1996, and 1995 the net number of subscribers added through system
acquisitions was approximately 58,500, 4,900 and 3,300, respectively. Removing
the effect of the Triad subscribers acquired in October 1997, the subscriber
growth would have been 42.4% during 1997.
 
     During the fourth quarter of 1997, the Company purchased from Triad the
cellular business and assets of 12 RSAs in Texas, Utah, Oklahoma and Minnesota.
This purchase was consummated on October 31, 1997. Therefore the operating
results of the Company's cellular business for the 12 months ended December 31,
1997 may not be indicative of future performance.
 
     The following table sets forth certain financial data as it relates to the
Company's cellular operations:

</TABLE>
 
  CELLULAR REVENUES
 
     Subscriber revenues have increased over the past three years due to the
growth in the number of subscribers offset slightly by a decrease in the average
monthly cellular subscriber revenue per subscriber. Average monthly cellular
subscriber revenue per subscriber was $51.13 in 1997, a 7.0% decline from $54.96
in 1996, which was a 4.0% decline from $57.25 in 1995. The Company anticipates
this downward trend will continue in 1998. 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.
 
                                       25
<PAGE>   27
 
     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 the Company expects total roamer minutes to
continue to increase, the decline in the rates charged between carriers will
limit the growth of roamer revenues.
 
     Cellular equipment sales, which consist primarily of handset sales,
decreased in 1997 primarily due to the decrease in the average cellular handset
sales price despite the increase in net subscriber additions.
 
  CELLULAR OPERATING EXPENSES
 
     The increase in cost of service is primarily attributable to the increased
number of subscribers. While cost of service increased in total dollars, it
decreased as a percentage of service revenues to 16.2% in 1997 from 19.3% in
1996 and 20.5% in 1995 due primarily to efficiencies gained from the growing
subscriber base.
 
     The Company's general and administrative costs are principally considered
to be variable costs, that is costs that will vary with the level of
subscribers. The increases in total dollars 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 $12.60
in 1997 from $14.58 in 1996 and $15.08 in 1995. While the Company has not
incurred material fraud or bad debt expenses to date and continues to develop
and invest in measures to minimize such expenses, there can be no assurance that
such expenses will not increase in the future.
 
     Increases in sales and marketing costs are primarily due to the increase in
net subscriber additions over the past three years. Although sales and marketing
costs have increased, sales and marketing cost per net subscriber added,
including the loss on equipment sales, declined to $574 in 1997 from $593 in
1996. This decrease is a result of strategically reduced advertising costs and
is partially offset by an increase in the churn (subscriber base attrition)
rate. Sales and marketing cost per net subscriber added increased to $593 in
1996 from $546 in 1995 largely due to an increase in the number of disconnected
subscribers relative to the number of gross subscriber additions. 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 primarily due to the increase in the
number of handsets sold in 1997 as compared to 1996 and 1995. Offsetting this
increase is a decrease caused by the decline in the average cost of handsets
sold.
 
     Increases in depreciation and amortization expense over the past three
years are primarily due to the purchase of additional wireless communications
system assets by the Company. 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, the Company
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.
 
  PCS OPERATIONS
 
     The Company's PCS business did not commence operations in any of its
markets until February 1996. From that date through the end of 1996, six of the
original seven MTA licenses purchased by the Company launched service at various
times. The last of the original seven MTA licenses, Denver, became operational
in May 1997. Due to the varying dates at which each of the
 
                                       26
<PAGE>   28
 
MTAs became operational, the expenses and revenues during any period may not be
representative of future operations. Additionally, during each period being
discussed a portion of the operating expenses incurred in the Company's PCS
operations were related to start-up costs incurred prior to the commencement of
operations in each of the systems. Exclusive of depreciation and amortization
expense, which was not material, approximately $5.4 million and $17.0 million of
start-up costs were incurred in 1997 and 1996, respectively.
 
     The Company had 128,600 PCS subscribers at December 31, 1997, representing
an increase of 262.3% during 1997. At December 31, 1996, the Company had 35,500
PCS subscribers.

</TABLE>
 
  PCS REVENUES
 
     PCS service revenues grew in 1997 primarily because all seven of the
original MTAs were operational during the majority of 1997 while these same MTAs
were only operational during a portion of 1996. Average monthly PCS subscriber
revenue per subscriber was $57.48 for 1997 as compared to $62.85 for 1996. As
the Company's PCS operations only began generating revenue during 1996, the year
over year trend is not necessarily representative of future trends.
 
     PCS equipment sales increased as a result of commercial operations in six
of the Company's PCS MTAs during the entire 12 months of 1997 and the Denver MTA
for eight months of 1997 as compared to only six MTAs having operations of
various lengths throughout 1996. The Company anticipates continued growth in
equipment sales as a result of increases in PCS subscriber additions and the
commencement of commercial operations in other PCS markets.
 
  PCS OPERATING EXPENSES
 
     Cost of service expenses, cost of equipment sales, and depreciation and
amortization expenses largely represent the expenses incurred by the operational
PCS systems. Six of the PCS MTAs were operational during the entire 12 months of
1997 and the Denver MTA was operational for eight months of that period. Six of
the PCS MTAs became operational during various times throughout 1996.
Accordingly, cost of service expenses, cost of equipment sales, and depreciation
and amortization expenses increased in 1997 over 1996. Similarly, general and
administrative costs increased due to the costs associated with supporting the
additional markets in which the Company has operations and sales and marketing
costs increased as a result of the effort to increase net subscriber additions
and promote the Company's PCS brand name. As the Company's PCS systems only
commenced operations during 1996, the year over year trend is not necessarily
representative of future trends.
 
                                       27
<PAGE>   29
 
OTHER INCOME (EXPENSE); EXTRAORDINARY LOSS; NET OPERATING LOSS CARRYFORWARDS
 
     Interest and financing expense, net of capitalized interest, increased in
1997 from 1996 and 1995 due to the increase in long-term debt. Long-term debt
was incurred primarily to fund the Company's capital expenditures associated
with the build-out of the Company's PCS systems. Interest expense will continue
to increase in 1998 as a result of increased borrowings the Company has
incurred, and will continue to incur, to fund this expansion. The weighted
average interest rate, before the effect of capitalized interest, was 10.2%,
9.8% and 9.2% in 1997, 1996 and 1995, respectively.
 
     Extraordinary loss on early extinguishment of debt of $6.6 million in 1995
represents the charge for the unamortized portion of financing costs incurred in
connection with the refinancing of the Company's then outstanding credit
facility.
 
     The Company had available at December 31, 1997, net operating loss
carryforwards ("NOLs") of approximately $640 million which will expire in the
years 2002 through 2012. The Company 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 the Company in July 1994. Approximately $17
million of such NOLs are subject to such limitations. Any amount of NOLs subject
to such limitation that the Company is not able to use in any one year may be
used in subsequent years prior to the expiration thereof. There is currently no
limitation on the remaining NOLs of $623 million. Management believes that,
based on a number of factors, there is sufficient uncertainty regarding the
utilization of all of the Company's NOLs. See Note 9 of the Company's Notes to
the consolidated financial statements.
 
EBITDA
 
     Consolidated EBITDA declined to negative $26.2 million in 1997 from
negative $7.1 million in 1996 and $25.5 million in 1995 primarily due to the
negative $130.1 million and negative $67.4 million EBITDA in 1997 and 1996,
respectively, attributable to PCS operations offset by an increase in cellular
EBITDA. Cellular EBITDA increased to $103.9 million in 1997 from $60.3 million
in 1996 and $28.9 million in 1995, primarily as 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 35.8% in 1997 from 28.3% in 1996 and
21.4% in 1995.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Credit Facility provides for $750 million of revolving credit and a
$200 million term loan. The PCS Vendor Facility provides for $300 million of
revolving credit. As of December 31, 1997, $695 million and $300 million were
outstanding under the Credit Facility and the PCS Vendor Facility, respectively.
As of December 31, 1997, $239 million were available for borrowing under the
Credit Facility, which availability is limited by certain financial covenants.
Indebtedness under the Credit Facility and the PCS Vendor Facility matures on
March 31, 2006, and December 31, 2003, respectively, and bears interest at
variable rates. Substantially all the assets of the Company, other than PCS
licenses acquired in the FCC's D and E auctions, certain licenses acquired in
the FCC's A and B auctions and certain other assets, are pledged as security for
such indebtedness. The terms of the PCS Vendor Facility restrict, among other
things, the sale of assets, distribution of dividends or other distributions and
loans by the subsidiary of Western PCS.
 
     In October 1997, the Company entered into an agreement with HTL and a
subsidiary of HTL pursuant to which the HTL subsidiary agreed to purchase
approximately 5.1% of the outstanding capital stock of the Company for a
purchase price of $74.3 million. This transaction closed in November 1997. The
proceeds from the sale of the stock were used to reduce amounts outstanding
under the Credit Facility. The Company and its subsidiary, Western PCS, also
entered into an agreement with HTL and another HTL subsidiary pursuant to which
the HTL subsidiary agreed to
                                       28
<PAGE>   30
 
purchase from Western PCS 19.9% of the outstanding capital stock of Western PCS
for an aggregate purchase price of $248.4 million. This transaction closed in
February 1998. Of such $248.4 million, approximately $113.4 million was paid to
the Company as a repayment of advances made to Western PCS as required by the
HTL Investment agreement which, in turn, was used by the Company to reduce
amounts outstanding under the Credit Facility.
 
     During 1998, the Company anticipates spending approximately $275 million to
complete construction of the build-out of the Seattle-Tacoma, Phoenix and Tuscon
BTA systems, to provide funds to Cook Inlet PCS for the build-out of certain BTA
markets and to expand the build-out of its PCS MTA systems. The Company will
utilize $135 million of the net proceeds of the HTL Investment, other cash on
hand, amounts available for borrowing under the Credit Facility, and if
available, other sources of funding, for such purposes. In addition, further
funds (which may be significant) will be required to finance the continued
growth of its PCS operations, provide for working capital and service debt. The
Company believes such sources will be sufficient for the operations of the
business. The Company continues to consider and expects to pursue additional
sources of funding to enable the further development of the PCS business. Such
sources may include the issuance of additional indebtedness and/or the sale of
additional equity at the parent or subsidiary level. There can be no assurance
that such funds will be available to the Company on acceptable or favorable
terms.
 
     Net cash used in operating activities was $114.5 million in 1997.
Adjustments to the $265.5 million net loss to reconcile to net cash used in
operating activities primarily included $133.5 million of depreciation and
amortization. Other adjustments included changes in operating assets and
liabilities, net of effects from consolidating acquired interests, consisting of
(i) an increase of $54.9 million in accrued liabilities, primarily attributable
to an increase in property taxes and interest, (ii) an increase of $23.9 million
in accounts receivable, net, as a result of the increase in total revenues, and
(iii) an increase of $16.9 million in prepaid expenses and other current assets,
primarily due to $15 million in escrow for the final payment to Triad which was
released in January 1998. Net cash used in operating activities was $61.3
million and $0.7 million in 1996 and 1995, respectively.
 
     Net cash used in investing activities was $652.3 million in 1997. Investing
activities for such period consisted primarily of (i) purchases of wireless
licenses and other intangible assets of $71.9 million, of which $71.6 was
attributable to the purchase of the PCS licenses for which the Company was the
high bidder in the FCC's D and E Block auctions, (ii) purchases of property and
equipment of $318.8 million, of which $264.4 million was attributable to PCS
capital expenditures incurred in relation to the build out and expansion of the
PCS MTAs, and (iii) acquisitions of wireless properties, net of cash acquired,
of $195.8 million, primarily attributable to the purchase of the Triad licenses
and properties during the fourth quarter of 1997. Net cash used in investing
activities was $489.1 million and $293.6 million in 1996 and 1995, respectively.
 
     Net cash provided by financing activities was $727.4 million in 1997.
Financing activities for such period consisted of $652 million of net additions
to long-term debt and the issuance of 3,888,888 shares of Class A Common stock
to HTL in November in consideration for $74.3 million. Net cash provided by
financing activities was $596.7 million and $295.1 million in 1996 and 1995,
respectively.
 
     In the ordinary course of business, the Company continues to evaluate
acquisition opportunities, joint ventures and other potential business
transactions. Such acquisitions, joint ventures and business transactions may be
material. Such transactions may also require the Company 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 the Company on acceptable or favorable terms.
 
     As previously mentioned, the Company 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
                                       29
<PAGE>   31
 
on the C and F Block license purchase prices. 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, the Company
has funded the operations of Cook Inlet PCS through the issuance of promissory
notes. At December 31, 1997, the Company had advanced funds totaling $36.0
million to Cook Inlet PCS under such promissory notes.
 
YEAR 2000 ISSUES
 
     The Company, like most owners and licensees of computer software, will be
required to modify significant portions of its software so that it will function
properly in the year 2000. Any of the Company's computer programs that have
date-sensitive software may recognize a date using "00" as the year 1900 rather
than the year 2000. This could result in a system failure or miscalculations
causing disruptions of operations, including, among other things, a temporary
inability to process transactions, send invoices or engage in similar normal
business activities. The Company is in the planning phase of its year 2000
compliance project and does not, as of yet, have a determinable estimate of the
costs to be incurred. The Company expects to incur internal staff costs as well
as consulting and other expenses related to infrastructure and facilities
enhancements necessary to prepare the systems for the year 2000. The Company
expects its year 2000 compliance project to be completed on a timely basis.
 
SEASONALITY
 
     The Company, and the wireless communications industry in general, have
historically experienced significant subscriber growth during the fourth
calendar quarter. Accordingly, during such quarter the Company experiences
greater losses on equipment sales and increases in sales and marketing expenses.
The Company has historically experienced highest usage and revenue per
subscriber during the summer months. The Company expects these trends to
continue.

                                    BUSINESS
INTRODUCTION
 
     Western Wireless provides wireless communications services in the western
United States. The Company owns an aggregate of 199 cellular and PCS licenses
for a geographic area covering approximately 68.0 million persons (counting only
once those persons that may be served by both cellular and PCS systems owned by
the Company). In addition, Western Wireless is a partner in ventures owning 25
PCS licenses for a geographic area covering approximately 15.5 million persons
(some of which overlap license areas owned by the Company). Western Wireless'
combined cellular and PCS licenses, together with licenses held by the ventures
in which it is a partner, cover approximately 59% of the land in the continental
United States. In its consolidated cellular and PCS markets, the Company served
648,600 subscribers at December 31, 1997.
 
     The Company operates its cellular systems under the CELLULAR ONE brand
name. It holds 88 cellular licenses and operates cellular systems in 72 RSAs and
16 MSAs with an aggregate population of approximately 7.3 million persons. The
Company's cellular systems cover over 95% of such population. In its
consolidated cellular markets, the Company served approximately 520,000
subscribers at December 31, 1997.
 
     The Company operates its PCS systems under its proprietary VoiceStream
brand name. Through Western PCS, the Company holds an 80.1% interest in 111
broadband PCS licenses and operates PCS systems in seven MTAs -- Honolulu, Salt
Lake City, El Paso/Albuquerque, Portland, Oklahoma City, Des Moines/Quad Cities
and Denver -- covering an aggregate population of approximately 20.2 million
persons. The Company obtained 96 of its broadband PCS licenses for BTAs in the
FCC's 1997 D and E Block auctions and acquired an additional eight PCS licenses
for BTAs through an acquisition; it has not yet commenced operations in any of
such BTA markets. Cook Inlet PCS, a partnership in which the Company holds a
49.9% limited partnership interest, owns broadband PCS licenses in 21 BTAs,
including seven that were acquired in the FCC's F Block auction in 1997. Cook
Inlet PCS initiated service using the VoiceStream brand name in the Tulsa,
Oklahoma BTA in June 1997. Through a joint venture, PCS service is available
under the VoiceStream brand name in the Wichita, Kansas BTA market. In its PCS
markets, the Company uses the internationally-proven GSM technology as the
network standard. GSM is the leading digital wireless standard worldwide, with
systems operating in approximately 109 countries, including the United States,
and serving over 80 million subscribers. In its consolidated PCS markets, the
Company served approximately 128,600 subscribers at December 31, 1997.
 
     Western Wireless is also engaged in activities related to its principal
wireless communications business. The Company has interests in entities which
own wireless licenses in certain foreign countries, including Ghana, Iceland and
the Republics of Latvia and Georgia. During 1997, the ventures in Latvia and
Georgia commenced operations. In addition, the Company has interests in entities
which have made wireless license applications in certain other foreign
countries. Finally, the Company operates paging systems in eight western states
and at December 31, 1997 served 31,900 paging customers.
 
  STRATEGY
 
     The Company's principal focus is on the operation of wireless
communications systems in the western United States. The Company believes that
cellular is the optimum technology for rural, less densely populated areas where
it can provide service on the most cost-effective basis, and that PCS is the
optimum technology for more densely populated urban areas where analog cellular
systems are more expensive to deploy and face potential capacity constraints.
The Company's acquisition of PCS licenses has enabled it to significantly expand
both its customer base and geographic coverage and to offer enhanced wireless
communications services. The Company's focus with its PCS licenses has been, and
will continue to be, to commence operations in the most densely populated areas
within its PCS systems.
 
                                       31
<PAGE>   33
 
     The Company's operating strategy is to (i) construct and commence
operations with high quality systems and extensive coverage in rural areas with
its cellular systems and in urban areas with its PCS systems; (ii) continue to
expand its operations through increased subscriber growth and usage; (iii)
utilize its centralized management and back office functions to support the
needs of its subscribers, thereby further improving operating efficiencies and
generating greater economies of scale; and (iv) strategically acquire cellular
and PCS properties. The Company is implementing its strategy by continuing to
build its PCS systems, offering a wide range of products and services at
competitive prices, continually upgrading the quality of its network,
establishing strong brand recognition, creating a strong sales and marketing
program tailored to local markets and providing a superior level of customer
service.
 
     The Company plans to continue to take advantage of opportunities to enter
new geographic markets, including international ventures. The Company also plans
to offer services as a Competitive Local Exchange Carrier (CLEC) in select
markets.
 
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 ESMR networks.
Historically, each application has been licensed and operates in a distinct
radio frequency block.
 
     Since its introduction in 1983, wireless service has grown dramatically. As
of June 30, 1997, according to Cellular Telecommunications Industry Association
("CTIA"), there were over 48.7 million wireless subscribers in the United
States, representing a penetration rate of 18% and a growth of 10.6% from
December 31, 1996.
 
     The following table sets forth certain domestic wireless industry
statistics derived from the data survey results published semi-annually by CTIA:

            SOURCE: CELLULAR TELECOMMUNICATIONS INDUSTRY ASSOCIATION
 
     In the wireless communications industry, there are two principal services
licensed by the FCC for transmitting voice and data signals, "cellular services"
and "PCS." Cellular service is the predominant form of wireless voice
communications service currently available. The FCC has made available for
cellular service a portion of the radio spectrum from 830-870 MHz. Cellular
service is capable of providing high quality, high capacity service to and from
mobile, portable and stationary telephones. Cellular handsets are affordable and
easy to use and offer important benefits to both business and residential
consumers. Fully equipped, multi-cell cellular systems are capable of handling
thousands of calls at any given time and thus are capable of providing service
to hundreds of thousands of subscribers in a given market. See "-- Products and
Services."
 
     Cellular systems are primarily analog based systems, although digital
technology has been introduced in certain markets. Analog technology currently
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). See "-- Operation of Wireless Communications Systems."
 
     PCS is a term commonly used in the United States to describe a portion of
radio spectrum (1850-1990 MHz). PCS spectrum was auctioned by the FCC beginning
with the A and B Blocks, which were auctioned by the FCC 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. 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 services. PCS also includes features that are not
generally offered by cellular providers, such as data transmissions to and from
portable computers, advanced paging services and facsimile services. In
addition, wireless providers may offer mass market wireless local loop
applications in competition with wired local communications services. See
"-- Governmental Regulation" for a discussion of the FCC auction process and
allocation of wireless licenses.

<PAGE>   35
 
     The Company, and the wireless communications industry in general, have
historically experienced significant subscriber growth during the fourth
calendar quarter. The Company has historically experienced highest usage and
revenue per subscriber during the summer months. The Company expects these
trends to continue.
 
  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,
cellular cells generally have a wider transmission radius than PCS cells. 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 cellular 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
interexchange 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.
 
     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. Cellular system operators normally agree to provide
service to subscribers from other cellular systems who are temporarily located
in or traveling through their service areas. 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.
 
     Although PCS and cellular systems utilize similar technologies and
hardware, they operate on different frequencies and use different technical and
network standards. As a result, and as discussed further below, it is often not
possible for users of one type of system to "roam" on a different type of system
outside of their service area, or to hand off calls from one type of system to
another. This is also true for PCS subscribers seeking to roam in a PCS service
area served by operators using different technical standards.
 
     PCS systems operate under one of three principal digital signal
transmission technologies, or standards, that have been proposed by various
operators and vendors for use in PCS systems: CDMA or TDMA. GSM and TDMA are
both "time division-based" standards but are incompatible with each other and
with CDMA. Accordingly, a subscriber of a system that utilizes GSM technology is
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. Such dual-mode
GSM handsets, while currently available from Nokia, may not be available in
adequate supply until the third quarter of 1998 and are more expensive than
single-mode handsets.
 
CELLULAR OPERATIONS
 
     The Company operates cellular systems in 72 RSAs and 16 smaller MSAs, and
generally owns 100% of each of its cellular licenses. In such rural markets, the
Company believes that its cellular systems, which can cover large geographic
areas with relatively few cell sites, provide the optimum
                                       34
<PAGE>   36
 
cost efficient wireless service technology. In contrast, PCS technology requires
more closely located cell sites to broadcast over extended geographic areas.
Accordingly, PCS service will be less efficient and more expensive to deploy in
rural markets than cellular service, making it likely that PCS competitors will
delay or avoid entry into such markets.
 
     The Company has experienced rapid growth of its cellular operations during
the last three years. The number of the Company's cellular subscribers grew to
520,000 at December 31, 1997 from 112,800 at December 31, 1994. Service
(subscriber, roamer and other) revenues grew to $290.5 million in 1997 from
$55.6 million in 1994 and operating income from cellular operations before
interest, taxes and depreciation and amortization increased to $103.9 million in
1997 from $2.1 million in 1994. The Company believes these results reflect the
strong demand for wireless services in its markets, the success of its marketing
strategy and its management capabilities. See "Risk Factors," "Selected
Consolidated Financial Data" and "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
     The Company believes based upon its experience that several attributes of
RSAs and small MSAs make such markets inherently 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 and less
competition.
 
     The Company 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 and no-answer transfer.
The Company provides extended regional and national service to cellular
subscribers in its markets, through its membership in NACN, 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.
 
     The Company has roaming arrangements with virtually every cellular carrier
in North America. The Company also has roaming arrangements with certain
cellular carriers in areas adjacent to the Company's markets that provide the
Company's customers attractive rates when roaming in these surrounding areas. In
addition, the Company has roaming arrangements with several PCS service
providers, including Sprint Spectrum, AT&T Wireless, AirTouch, Southwestern Bell
and PrimeCo., that allow their customers to roam in the Company's cellular
markets with dual-mode handsets.
 
CELLULAR MARKETS AND SYSTEMS
 
     The Company owns FCC licenses to provide wireless cellular communications
services in 88 separate markets. The Company's pops by cellular market are as

(2) Estimated 1998 populations are based on 1997 estimates by Equifax adjusted
    by the Company by a growth factor based upon Equifax's growth factors from
    1995 to 1997.
 
(3) The population for Idaho 2 includes 5,000 persons in Idaho 3 because the
    Company has construction permits under its Idaho 2 license to build Cell
    Cites to cover such persons.

(4) The Company has entered into a definitive purchase agreement for this
    market. The transaction is expected to close during the third quarter of
    1998. The Company previously operated this market under an IOA.
 
PCS OPERATIONS
 
     Through Western PCS, the Company holds an 80.1% interest in 111 PCS
licenses, covering approximately 64.2 million persons. The Company operates PCS
systems in the Honolulu, Salt Lake City, El Paso/Albuquerque, Portland, Oklahoma
City, Des Moines/Quad Cities and Denver MTAs, and is constructing the initial
phase of its PCS systems in the Seattle-Tacoma, Phoenix and Tucson BTAs. The
Company has not yet finalized its construction plans for all of the licenses
purchased in the D and E Block auctions. Cook Inlet PCS provides service in the
Tulsa, Oklahoma BTA utilizing the VoiceStream brand name, and is in the planning
stage of developing a PCS system in the Spokane BTA. Through joint ventures, PCS
services are offered or will be offered under the VoiceStream brand name in the
Wichita, Kansas BTA with Omnipoint Corp. and certain BTAs in Iowa with Iowa
Network Services.
 
     The Company has experienced rapid growth of its PCS operations since
inception in February 1996. During such period, the number of the Company's PCS
subscribers grew to 128,600 at December 31, 1997 and service (subscriber, roamer
and other) revenues grew to $52.6 million for 1997. The Company believes these
results reflect the strong demand for wireless services in its markets, the
success of its marketing strategy and its management capabilities. See "Risk
Factors," "Selected Consolidated Financial Data" and "Management's Discussion
and Analysis of Financial Condition and Results of Operations."
 
     The Company believes its PCS service offerings are broader than those
generally offered by cellular systems in the Company's PCS markets. PCS 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.
 
     The Company's goal is to achieve significant market penetration by
aggressively marketing competitively priced PCS services under its proprietary
VoiceStream brand name, offering enhanced services not generally provided by
cellular operators and providing superior customer service. In addition, the
Company is well-positioned to be a low-cost provider of PCS services by taking
advantage of the existing business infrastructure, including centralized
management, marketing, billing and customer service functions, and by focusing
on efficient customer acquisition and retention.
 
     The Company's experience is that PCS technology is better suited to urban
areas than rural areas and has cost advantages relative to cellular technology
in urban areas. PCS cell sites operate at a higher frequency and lower power
than cellular cell sites and, therefore, typically have a smaller coverage area.
Unlike rural areas, wireless systems in urban areas require substantial
frequency "reuse" to provide high capacity. The coverage advantage that cellular
frequencies and analog technology enjoy in rural areas is not present in urban
areas because analog cellular technology does not provide efficient frequency
reuse. As a result, the higher frequency, lower power, digital PCS systems are
likely to provide greater capacity in urban areas.
 
     The Company selected GSM as the digital standard for its PCS system because
the Company believes it has significant advantages over the other competing
digital standards, including the experience of years of proven operability in
Europe and Asia, enhanced features and an open system architecture that will
allow the Company to choose from a variety of equipment options and providers.
GSM is the leading digital wireless standard in the world, with over 80 million
customers in 109 countries.
 
     The Company has entered into roaming agreements with substantially all of
the licensees that have chosen to deploy the GSM standard in their PCS markets
in the United States which will
 
                                       38
<PAGE>   40
 
provide for roaming by the Company's PCS subscribers into these carriers' PCS
markets, and vice versa, when such systems are operational. The Company also has
over 70 reciprocal roaming agreements with a variety of international carriers
who have chosen to deploy the GSM standard.
 
PCS MARKETS AND SYSTEMS
 
     The Company owns 80.1% of Western PCS which holds 111 FCC licenses to

PRODUCTS AND SERVICES
 
     The Company provides a variety of wireless products and services designed
to match a range of needs for business and personal use.
 
  CELLULAR
 
     The Company 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 and no-answer transfer.
In addition, all subscribers can access local govern-
 
                                       42
<PAGE>   44
 
ment emergency services from their cellular handsets (with no air time charge)
by dialing 911 where coverage is available. The Company will continue to
evaluate new products and services that may be complementary to its wireless
operations. The Company 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 the Company separately
charges for its custom calling features.
 
     The Company provides extended regional and national service to cellular
subscribers in its markets, through its membership in NACN, 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. The Company also has
special roaming arrangements with certain cellular carriers in areas adjacent to
the Company's markets that provide the Company's customers attractive rates when
roaming in these surrounding areas.
 
  PCS
 
     The Company currently offers several distinct services and features in its
PCS systems, including:
 
     -  Enhanced Features -- The Company's PCS 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.
 
     -  Messaging and Wireless Data Transmission -- Digital networks offer voice
        and data communications, including text messaging, through a single
        handset. The Company believes that, as data transmission services
        develop, a number of uses for such services will emerge.
 
     -  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.
 
     -  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.
 
     -  Over-the-Air Activation and Over-the-Air Subscriber Profile
        Management -- The Company 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.
 
     -  Extended Battery Performance -- Digital handsets are capable of entering
        into a "sleep" mode when not in use, significantly extending the
        handset's battery performance. In addition, because the Company's PCS
        systems utilize tightly spaced, low power transmitters, less power is
        required to transmit calls, thereby further extending battery
        performance.
 
     -  Roaming -- Subscribers are able to roam in substantial portions of 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. The Company has entered into roaming agreements which
        allow its PCS customers to roam on cellular systems. Dual-mode handsets
        are commercially available from one manufacturer that allow roaming onto
        analog cellular systems.
 
MARKETING, SALES AND CUSTOMER SERVICE
 
     The Company's sales and marketing strategy is to generate continued net
subscriber growth and increased subscriber revenues. In addition, the Company
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. The Company markets its services under nationally recognized and
                                       43
<PAGE>   45
 
proprietary brand names, and sells its products and services through a
combination of direct and indirect distribution channels.
 
  MARKETING
 
     The Company markets its cellular products and services in all markets
principally 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 the 50 states with a combined estimated population of over
191 million. The national advertising campaign conducted by the Cellular One
Group enhances the Company's advertising exposure at a lesser cost than what
could be achieved by the Company alone.
 
     The Company markets its PCS products and services under its proprietary
VoiceStream brand name. The Company'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, the Company emphasizes the
enhanced features, privacy and competitive pricing of such services. The Company
concentrates its PCS marketing efforts primarily on businesses and individuals
"on-the-go," which benefit from integrated mobile voice, messaging and wireless
data transmission capabilities, and subscribers with substantial needs for
wireless communications, who benefit from enhanced features and services.
 
  SALES
 
     The Company sells its products and services through a combination of direct
and indirect channels. The Company operates 234 local sales offices (which also
serve as retail sales locations), including 149 under the CELLULAR ONE brand
name, 14 under the CelluarOne Express brand name and 71 under the VoiceStream
brand name, and utilizes a direct sales force of over 1,150 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.
 
     The Company believes that its local sales offices provide the physical
presence in local markets necessary to position the Company as a quality local
service provider, and give the Company greater control over both its costs and
the sales process. The Company also utilizes indirect sales through an extensive
network of national and local merchant and specialty retailers. The Company
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, the Company 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, the
Company has historically sold handsets below cost to respond to competition and
in accordance with general industry practice and expects to continue to do so in
the future.
 
  CUSTOMER SERVICE
 
     Customer service is a significant element of the Company's operating
philosophy. The Company is committed to attracting and retaining subscribers by
providing consistently superior customer service. At its headquarters in
Issaquah, Washington, the Company 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.
 
     The Company implements credit check procedures at the time of sale and
continuously monitors customer churn (the rate of subscriber attrition). The
Company believes that it helps manage its churn through an outreach program by
its sales force and customer service personnel.
 
                                       44
<PAGE>   46
 
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 voice mail, call waiting and call forwarding.
 
     The Company opened a customer call center in Albuquerque, New Mexico,
during the second half of 1997. This facility, along with the Company's customer
call center in Issaquah, Washington, supports the Company's current cellular and
PCS customers and will be able to support the Company's expected subscriber
growth for the foreseeable future. As these customer call centers are in
different regions of the country, they will also provide backup for one another
in case of natural disaster, which will allow the Company to maintain continuous
customer service.
 
SUPPLIERS AND EQUIPMENT VENDORS
 
     The Company does not manufacture any of the handsets or Cell Site equipment
used in the Company's operations. The high degree of compatibility among
different manufacturer's models of handsets and Cell Site equipment allows the
Company 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 Company's operations are available for purchase from multiple sources,
and the Company anticipates that such equipment will continue to be available in
the foreseeable future. The Company currently purchases handsets primarily from
Motorola, Inc., Ericsson Inc., Mitsubishi Wireless Communications, Inc., NEC of
America, Inc. and Nokia. GSM dual-mode handsets are currently only commercially
available from Nokia. The Company currently purchases Cell Site and switching
equipment primarily from NORTEL, Lucent Technologies and Nokia.
 
COMPETITION
 
     Competition for subscribers among wireless licensees is based principally
upon the services and features offered, the technical quality of the wireless
system, customer service, system coverage, capacity and price. Such competition
may increase to the extent that licenses are transferred from smaller,
stand-alone operators to larger, better capitalized and more experienced
wireless communications operators who may be able to offer subscribers certain
network advantages similar to those offered by the Company.
 
     Under current FCC rules, there may be up to six PCS licenses in each
geographic area in addition to the two existing cellular licenses. Also, the FCC
has licensed SMR dispatch system operators to construct 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 the
Company operates. The Company has one cellular competitor in each of its
cellular markets including AirTouch, Aliant, CommNet, Kansas Cellular,
Southwestern Bell Mobile Systems and US Cellular, and there may be as many as
six PCS licensees in each of its markets. Currently, the Company's principal
competitors in its PCS business are PrimeCo, Sprint Spectrum and AT&T Wireless,
as well as the two existing cellular providers in its PCS markets. ESMR systems,
including those operated by Nextel, are competitive with the Company's cellular
and PCS systems. The Company also competes with paging, dispatch and
conventional mobile telephone companies, resellers and landline telephone
service providers in its cellular and PCS markets. Potential users of cellular
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, cellular service may also compete more directly with traditional
landline telephone service providers.
 
     The Company's PCS business directly competes with existing cellular service
providers in its PCS markets, many of which have been operational for a number
of years and may have significantly greater financial and technical resources
than those available to the Company and who
 
                                       45
<PAGE>   47
 
may upgrade their systems to provide comparable services in competition with the
Company's PCS systems. These cellular competitors include AT&T Wireless,
AirTouch and US Cellular.
 
     The FCC requires all cellular and PCS licensees to provide service to
"resellers." A reseller provides wireless service to customers but does not hold
an FCC license or own facilities. Instead, the reseller buys blocks of wireless
telephone numbers and capacity from a licensed carrier and resells service
through its own distribution network to the public. Thus, a reseller is both a
customer of a wireless licensee's services and also a competitor of that
licensee. Several small resellers currently operate in competition with the
Company's systems. 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, the Company 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.
 
     The Company recognizes that technological advances and changing regulations
have led to rapid evolution of the wireless telecommunications industry. At the
end of 1996, the FCC, as required by the Omnibus Budget Reconciliation Act of
1993, transferred 200 MHz of spectrum previously allocated to Federal Government
use to the private sector. In April 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 April 1998, the FCC concluded the auction of more than
1000 MHz of spectrum for the Local Multipoint Distribution Service, in which the
Company was the winning bidder on 51 BTA licenses covering more than 11 million
pops within the geographic areas covered by its existing cellular and PCS
licenses. The FCC also plans in 1998 to auction 25 MHz of spectrum for the
General Wireless Communications Service, plus additional spectrum in the 220 MHz
and 39 GHz bands. The Company 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.
 
GOVERNMENTAL REGULATION
 
     The FCC regulates the licensing, construction, operation, acquisition and
sale of cellular and PCS 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 COMMUNICATIONS 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
 
                                       46
<PAGE>   48
 
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 the Company's
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. The Company has approximately 35 cellular licenses which
will be subject to renewal in the next three years. While the Company 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.
 
     Cellular and 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 the Company's activities. The Company 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.
 
     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 ("PMRS"), which CMRS includes
cellular (and PCS) service.
 
  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 (pro forma transfer of control does not require prior FCC
approval). Subject to FCC approval, a license or permit may be transferred from
a nonwireline 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 the Company 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 the Company, 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 the Company
than on any other prospective buyer.
 
                                       47

  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 six licensees will compete in each PCS service
area. The FCC has allocated 120 MHz of radio spectrum in the 2 GHz band for
licensed broadband 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) 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 has been or 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 Block licenses is
currently scheduled for the second half of 1998.
 
     Under the FCC's current rules specifying spectrum aggregation limits
affecting broadband PCS licensees, no entity may hold licenses for more than 45
MHz of PCS, cellular and SMR services regulated as CMRS where there is
significant overlap in any geographic area (significant overlap will occur when
at least 10% of the population of the PCS licensed service area is within the
CGSA(s) and/or SMR service area(s)).
 
     The Company owns cellular licenses serving markets that are wholly or
partially within the Denver MTA and the Oklahoma City MTA, resulting in the
Company exceeding the FCC's current 45 MHz CMRS crossownership restriction
described above. The Company 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, the Company will be obligated to divest sufficient portions of its
Denver and Oklahoma City PCS markets or its cellular holdings to come into
compliance with the rules. The Company does not believe such restriction or any
actions the Company is required to take to comply therewith will have a material
adverse effect on the Company.
 
     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 the Company, must
construct facilities that offer coverage to one-third of the population of their
service area within five years of their initial license grants and to two-thirds
of the population within ten years. All 10 MHz PCS licensees, including the
Company, must construct facilities that offer coverage to one-fourth of the
population of their service area within five years of their initial license
grants or make a showing of substantial service. 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 unjust enrichment penalties,
i.e., forfeiture of any
 
                                       48
<PAGE>   50
 
bidding credits and acceleration of any installment payment plans should the
assignee or transferee not qualify for the same benefits. 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 10 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, the Company will need to
relocate many of these incumbent licensees. In an effort to balance the
competing interests of existing microwave users and newly authorized PCS
licensees, the FCC has adopted (i) a transition plan to relocate such microwave
operators to other spectrum blocks and (ii) a cost sharing plan so that if the
relocation of an incumbent benefits more than one PCS licensee, the benefiting
PCS licensees will share the cost of the relocation. Initially, this transition
plan allowed most microwave users to operate in the PCS spectrum for a two-year
voluntary negotiation period and an additional one-year mandatory negotiation
period. 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.
 
  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 (pro forma
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 the Company 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.
 
  FOREIGN OWNERSHIP
 
     Under the Communications Act, no more than 25% of the capital stock of an
entity that controls an FCC licensee may be indirectly owned or voted by
non-U.S. citizens or their representatives, by a foreign government, or by a
foreign corporation, absent a 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
 
                                       49
<PAGE>   51
 
on foreign ownership in an FCC licensee itself remains fixed at 20%, with no
opportunity to increase the percentage, and is unaffected by the FCC's new
rules.
 
     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. The Company 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 the Company'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.
 
     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 providers 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
                                       50
<PAGE>   52
 
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 U.S. 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 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. The Company 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. The Company can
not predict the outcome of such challenges.

Common Stock.
 
COMMON STOCK
 
     The Company has two classes of authorized Common Stock, Class A Common
Stock, which is being offered in the Offerings, and Class B Common Stock. Other
than with respect to voting rights, the Class A and Class B have identical
rights. The Class A Common Stock has one vote per share and the Class B Common
Stock has ten votes per share. Shares of Class B Common Stock generally convert
automatically into shares of Class A Common Stock on a share-for-share basis
immediately upon any transfer of the Class B Common Stock other than a transfer
from an original holder of Class B Common Stock to certain affiliates of such
holder.
 
     Holders of Common Stock have no cumulative voting rights and no preemptive,
subscription or sinking fund rights. Subject to preferences that may be
applicable to any then outstanding Preferred Stock, holders of Common Stock will
be entitled to receive ratably such dividends as may be declared by the Board of
Directors out of funds legally available therefor. See "Price Range of Class A
Common Stock and Dividend Policy." In the event of a liquidation, dissolution or
winding up of the Company, holders of Common Stock will be entitled to share
ratably in all assets remaining after payment of liabilities and the liquidation
preference to any then outstanding Preferred Stock.
 
     The Company's Articles of Incorporation permit the redemption of the
Company's Common Stock from shareholders where necessary to protect the
Company's regulatory licenses.
 
PREFERRED STOCK
 
     Pursuant to its Articles of Incorporation, the Company is authorized to
issue 50,000,000 shares of Preferred Stock, which may be issued from time to
time in one or more classes or series or both upon authorization by the
Company's Board of Directors. The Board of Directors, without further approval
of the shareholders, is authorized to fix the dividend rights and terms,
conversion rights, voting rights, redemption rights and terms, liquidation
preferences and any other rights, preferences, privileges and restrictions
applicable to each class or series of Preferred Stock. The issuance of Preferred
Stock, while providing flexibility in connection with possible acquisitions and
other corporate purposes, could, among other things, adversely affect the voting
power of the holders of Common Stock and, under certain circumstances, make it
more difficult for a third party to gain control of the Company, discourage bids
for the Company's Common Stock at a premium or otherwise adversely affect the
market price of the Class A Common Stock.
 
     The Company has no current plans to issue any Preferred Stock.
 
CERTAIN ARTICLES OF INCORPORATION, BYLAWS AND STATUTORY PROVISIONS AFFECTING
SHAREHOLDERS
 
  SPECIAL MEETINGS OF SHAREHOLDERS; SHAREHOLDER ACTION BY WRITTEN CONSENT
 
     The Company's Bylaws provide that any action required or permitted to be
taken by the Company's shareholders may be effected at a duly called annual or
special meeting of shareholders or by unanimous consent in writing.
Additionally, the Articles of Incorporation and Bylaws provide that special
meetings of the shareholders of the Company may be called only by a majority of
the Board of Directors or an authorized committee thereof.
 
                                       56
<PAGE>   58
 
  ADVANCE NOTICE REQUIREMENTS FOR SHAREHOLDER PROPOSALS AND DIRECTOR NOMINATIONS
 
     The Company's Bylaws provide that shareholders seeking to bring business
before or to nominate directors at any meeting of shareholders must provide
timely notice thereof in writing. To be timely, a shareholder's notice must be
delivered to, or mailed and received at, the principal executive offices of the
Company not less than (i) with respect to an annual meeting, 120 calendar days
in advance of the one-year anniversary of the date that the Company's proxy
statement was released to shareholders in connection with the previous year's
annual meeting, except that if no annual meeting was held in the previous year
or if the date of the annual meeting has been changed by more than 30 calendar
days from the date contemplated at the time of the previous year's proxy
statement, such notice must be received by the Company a reasonable time before
the Company's proxy statement is to be released and (ii) with respect to a
special meeting of shareholders, a reasonable time before the Company's proxy
statement is to be released. The Bylaws also specify certain requirements for a
shareholder's notice to be in proper written form. These provisions may preclude
some shareholders from bringing matters before the shareholders or from making
nominations for directors.
 
  DIRECTOR AND OFFICER INDEMNIFICATION
 
     The Washington Business Act provides that a Washington corporation may
include provisions in its articles of incorporation relieving each of its
directors of monetary liability arising out of his or her conduct as a director
for breach of his or her fiduciary duty except liability for (i) acts or
omissions of a director that involve intentional misconduct or a knowing
violation of law, (ii) conduct in violation of Section 23B.08.310 of the
Washington Business Act (which section relates to unlawful distributions) or
(iii) any transaction from which a director personally received a benefit in
money, property or services to which the director was not legally entitled. The
Company's Articles of Incorporation include such provisions.
 
     The Company's Articles of Incorporation and Bylaws provide that the Company
shall, to the fullest extent permitted by the Washington Business Act, as
amended from time to time, indemnify and advance expenses to each of its
currently acting and former directors and officers, and may so indemnify and
advance expenses to each of its current and former employees and agents. The
Company believes the foregoing provisions are necessary to attract and retain
qualified persons as directors and officers. Prior to the consummation of the
Offerings, the Company intends to enter into separate indemnification agreements
with each of its directors and executive officers in order to effectuate such
provisions, which agreements will supersede prior indemnification agreements
entered into by the Company with each of its directors and executive officers.
 
  REGULATED SHAREHOLDERS
 
     The Articles of Incorporation contain provisions that would effectively
preclude each of Goldman Sachs and its affiliates from voting that number of
shares of Common Stock which results in such shareholder or its affiliates
having the right to vote more than 24.9% of the Company's total voting power.
 
  PROVISIONS AFFECTING ACQUISITIONS AND BUSINESS COMBINATIONS
 
     The Washington Business Act, Section 23B.19 of the Revised Code of
Washington, prohibits a "target corporation," with certain exceptions, from
engaging in certain "significant business transactions" (such as a merger or
sale of assets) with an "acquiring person" who acquires more than 10% of the
voting securities of the target corporation for a period of five years after
such acquisition, unless the transaction is approved by a majority of the
members of the target corporation's board of directors prior to the date of the
transaction or unless the aggregate amount of the cash and the market value of
non-cash consideration received by holders of outstanding shares of any class or
series of stock of the target corporation is equal to certain minimum amounts.
 
                                       57
<PAGE>   59
 
The Company's Articles of Incorporation provide that it will be subject to such
prohibitions and shall remain subject to such prohibitions even if they are ever
repealed. Such prohibitions do not apply to any shareholders who beneficially
own ten percent or more of the Company's outstanding voting securities prior to
the Offerings.
 
TRANSFER AGENT AND REGISTRAR
 
     The Company's transfer agent and registrar for its Class A Common Stock is
ChaseMellon Shareholder Services, New York, New York.
 
                        VALIDITY OF CLASS A COMMON STOCK

                    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, 1997 and 1996, and the
related consolidated statements of operations, shareholders' equity and cash
flows for each of the three years in the period ended December 31, 1997. These
financial statements and schedules referred to below are the responsibility of
the Company's 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, 1997 and 1996, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1997, 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 (the "Company") provides wireless
communications services in the western 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 the Company's belief that there
are certain strategic advantages to operating each technology in these
respective areas. As of December 31, 1997, the Company provides cellular
services in 72 Rural Service Areas ("RSA") and 16 Metropolitan Statistical Areas
("MSA") and PCS services in nine metropolitan markets in seven Metropolitan
Trading Areas ("MTA").
 
     The Company expanded its cellular footprint in 1997 by acquiring 12 RSAs
from Triad Corporation, Triad Cellular L.P. and certain of their affiliates
(collectively "Triad") (see Note 12). Also during 1997 the Company acquired 100
additional PCS licenses in the Federal Communication Commission's ("FCC") D and
E Block auctions and acquired eight more PCS licenses as part of its acquisition
of Triad. Cook Inlet Western Wireless PV/SS PCS, LP ("Cook Inlet PCS"), a
partnership in which the Company holds a 49.9% limited partnership interest,
owns broadband PCS licenses in 21 Basic Trading Areas ("BTA") including seven
that were acquired in the FCC F Block auction during the first quarter of 1997.
The first of these BTAs commenced commercial operations in June 1997 .
 
     The Company expects to incur significant operating losses and to generate
negative cash flows from operating activities during the next several years
while it develops and constructs its PCS systems and builds a PCS customer base.
 
 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Principles of consolidation
 
     The consolidated financial statements include the accounts of the Company,
its wholly owned subsidiaries and its affiliate investments in which the Company
has a greater than 50% interest that is not temporary. All affiliate investments
in which the Company has between a 20% and 50% interest and those that are
temporarily greater than 50% 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.

 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 ten years.
 
  Licensing costs and other intangible assets and amortization
 
     Licensing costs primarily represent costs incurred to acquire FCC wireless
licenses, including cellular licenses obtained by the Company, principally
through acquisitions, and PCS licenses which were primarily purchased from the
FCC.
 
     Amortization of cellular licenses is computed using the straight-line
method. During 1996 the Company amortized its cellular licensing costs over 15
years. Effective January 1, 1997, the Company 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 which have terms ranging from 9 to 10 years.
 
  Capitalized Interest
 
     The Company's PCS licenses represent qualified assets pursuant to Statement
of Financial Accounting Standards ("SFAS") No. 34, "Capitalization of Interest
Cost." For the years ended December 31, 1997, 1996, and 1995, the Company had
interest expense of $99.0 million, $44.7 million and $25.4 million,
respectively, net of capitalized interest in the amount of $4.0 million, $5.2
million and $0.4 million, respectively, pertaining to the build out of its PCS
markets.
 
  Income taxes
 
     The Company accounts for deferred taxes using the asset and liability
method.
 
  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
 
     The Company accounts for its stock-based compensation plans under APB
Opinion No. 25, "Accounting for Stock Issued to Employees." See Note 11 for
discussion of the effect on net loss and other related disclosures had the
Company accounted for these plans under SFAS No. 123, "Accounting for
Stock-Based Compensation."

 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
  Financial instruments
 
     As required under the Credit Facility (as defined in Note 7), the Company
enters into interest rate swap and cap agreements to manage interest rate
exposure pertaining to long-term debt. The Company has only limited involvement
with these financial instruments, and does not use them for trading purposes. In
addition, the Company has historically held derivative financial instruments to
maturity and has never recognized a gain or loss on disposal. It is the
Company's 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 the Company 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
the Company's financial instruments.
 
     The carrying value of the Company's 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. The Company does not hold
or issue any financial instruments for trading purposes.
 
  Supplemental cash flow disclosure
 
     Cash paid for interest (net of amounts capitalized) was $87.4 million,
$36.2 million, and $21.7 million for the years ended December 31, 1997, 1996 and
1995, respectively.
 
     Non-cash investing and financing activities were as follows:

  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 1997 presentation.

</TABLE>
 
 (a) Credit Facility
 
     The Company has a credit facility with a group of banks (the "Credit
Facility") pursuant to which the banks agreed to make loans to the Company, on a
revolving-credit basis, in an aggregate principal amount not to exceed $750
million (the "Revolving Loans") and a term loan (the "Term Loan") of $200
million. The Revolving Loans are limited to the principal amount outstanding on
December 31, 2000. The Company is required to make quarterly payments on the
outstanding principal of the Revolving Loans and Term Loan beginning March 31,
2001, and June 30, 2001, respectively. These payments increase each year on the
anniversary date of the initial payment, until paid in full on December 31,
2005, for the Revolving Loans and March 31, 2006, for the Term Loan. The Credit
Facility also contains certain financial covenants, the most restrictive of
which impose limitations on the incurrence of indebtedness.
 
     Any loan shall, at the option of the Company, be made as a Base Rate
Advance, Eurodollar Advance or CD Rate Advance. Under the Credit Facility,
interest is payable at an applicable margin in excess of the prevailing base
rate. The applicable margin on the Revolving Loans is determined quarterly based
on the leverage ratio of the Company, excluding certain of its subsidiaries. The
applicable margin on the Term Loan is 2.5%. During 1997 and 1996, all loans
under the Credit Facility had been borrowed using the Eurodollar option. The
weighted average interest rate, including the appropriate applicable margin, for
the years ended December 31, 1997 and 1996, was 8.22% and 7.79%, respectively.
The Credit Facility also provides for an annual fee ranging from 0.25% to 0.375%
on the unused commitment, payable quarterly. As of December 31, 1997 and 1996,
the unused portion of the commitment under the Credit Facility was $239 million
and $750 million, respectively.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
 7. LONG-TERM DEBT (CONTINUED)
     The Credit Facility requires the Company to enter into interest rate swap
and cap agreements to manage the interest rate exposure pertaining to borrowings
under the Credit Facility. At December 31, 1997 and 1996, the Company had
entered into interest rate caps and swaps with a total notional amount of $365
million and $205 million, respectively. 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 7.40% and 6.76% at December 31, 1997 and 1996, respectively.
The amount of unrealized loss attributable to changing interest rates at
December 31, 1997 and 1996, was immaterial.
 
     The repayment of the Credit Facility is secured by, among other things, the
grant of a security interest in substantially all of the assets of the Company,
excluding, among other items, the capital stock and assets of the PCS
subsidiaries.
 
     Upon execution of the Credit Facility, the Company repaid all of its
outstanding indebtedness under its then existing revolving/term loan agreement
(the "Previous Agreement"). The Company incurred an extraordinary loss of
approximately $6.6 million in connection with the early repayment of the
outstanding indebtedness under the Previous Agreement during 1995. The loss
primarily consisted of the write-off of the related financing costs which had
been deferred and only partially amortized.
 
  (b) 10 1/2% Senior Subordinated Notes Due 2006
 
     In May 1996, the Company issued $200 million principal amount of 10 1/2%
Senior Subordinated Notes Due 2006 (the "2006 Notes") at par. The 2006 Notes
mature on June 1, 2006. Interest is payable semi-annually. The 2006 Notes may be
redeemed at any time at the option of the Company, in whole or from time to time
in part, at varying redemption prices. The Credit Facility prohibits the
repayment of all or any portion of the principal amount of the 2006 Notes prior
to the repayment of all indebtedness under the Credit Facility. The 2006 Notes
contain certain restrictive covenants which impose limitations on the operations
and activities of the Company 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 Credit
Facility and the PCS Vendor Facility (see item (d) below).
 
  (c) 10 1/2% Senior Subordinated Notes Due 2007
 
     In October 1996, the Company issued $200 million principal amount of
10 1/2% Senior Subordinated Notes, which will mature on February 1, 2007 (the
"2007 Notes") at par. Interest is payable semi-annually commencing February 1,
1997. 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 the Company, in whole or from
time to time in part, at varying redemption prices. The Credit Facility
prohibits repayment of all or any portion of the principal amount of the 2007
Notes prior to the repayment of all indebtedness under the 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
Credit Facility and the PCS Vendor Facility.
 
  (d) PCS Vendor Facility
 
     A subsidiary of the Company has a credit facility (the "PCS Vendor
Facility" formerly known as the "NORTEL Facility") with a consortium of lenders
which expires on December 31, 2003. In the

 7. LONG-TERM DEBT (CONTINUED)
first quarter of 1997 this agreement was amended to increase the credit facility
from $200 million to $300 million. The PCS Vendor Facility bears interest at a
rate approximating the prime rate plus a margin of 1.5%, or the London Interbank
Offered Rate ("LIBOR") plus a margin of 2.5%. As of December 31, 1997, all
outstanding borrowings were drawn under the LIBOR rate option. The weighted
average interest rate, including margin, for the years ended December 31, 1997
and 1996, was 8.20% and 8.06%, respectively. The PCS Vendor Facility contains
certain financial covenants, the most restrictive of which impose a minimum cash
coverage and is collateralized by substantially all of the subsidiary's assets
and the stock of such subsidiary. The terms of this agreement restrict, among
other things, the sale of assets, distribution of dividends or other
distributions and loans by the subsidiary of the Company. Interest only payments
are required through September 30, 2000. Commencing September 30, 2000, and at
the end of each calendar quarter thereafter, the subsidiary is required to make
payments on the principal amount outstanding under the PCS Vendor Facility in
increasing quarterly installments.
 
     The aggregate amounts of principal maturities as of December 31, 1997, of
the Company's debt are as follows (dollars in thousands):

taxes, insurance and normal maintenance costs. Substantially all of the
Company's leases have fixed minimum lease payments.
 
     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, 1997, are summarized below (dollars in thousands):

 8. COMMITMENTS (CONTINUED)
     In order to ensure adequate supply and availability of certain inventory
requirements and service needs, the Company has committed to purchase from
various suppliers wireless communications equipment, handsets, and services.
These agreements expire at various dates through December 2005. The aggregate
amount of these commitments total approximately $401 million. At December 31,
1997, the Company has ordered approximately $246 million under all of these
agreements, of which approximately $16 million is outstanding.
 
     In March 1998, a subsidiary of the Company entered into an agreement with a
vendor to purchase $150 million of PCS equipment and services in relation to the
buildout of its Seattle and Phoenix BTAs.
 
     The Company has various other purchase commitments for materials, supplies
and other items incident to the ordinary course of business which are neither
significant individually nor in the aggregate. Such commitments are not at
prices in excess of current market value.

     For tax purposes, the Company had available at December 31, 1997, net
operating loss carryforwards for regular tax purposes of approximately $640
million which will expire in 2002 through 2012. The Company 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 the Company in July 1994. The
change in the valuation allowance was an increase of approximately $107 million,
$56 million and $16 million in 1997, 1996 and 1995, respectively.
 
     Management believes that, based on a number of factors, 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 the Company's PCS business and
expected increased competition from new entrants into the Company's existing
markets. Accordingly, a valuation allowance has been provided for the net
deferred tax assets of the Company.
 
     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 the Company is primarily due to the Company's full valuation
allowance against its net deferred tax assets.

10. SHAREHOLDERS' EQUITY
 
  (a) Business combinations
 
     On October 31, 1997, the Company issued 1,600,000 shares of its Class A
Common Stock as a portion of the consideration given to purchase the cellular
business and assets of Triad (see Note 12).
 
     On December 29, 1995, the shareholders of the Company, Palouse Paging Inc.
("Palouse"), and Sawtooth Paging Inc. ("Sawtooth") approved the merger of
Palouse and Sawtooth into wholly owned subsidiaries of the Company. During 1995,
certain officers, one of whom is a director, of the Company who are also
shareholders of Palouse and Sawtooth provided Palouse and Sawtooth with
short-term financing. During 1996, shareholders of Palouse and Sawtooth
exchanged their shares for 515,561 and 79,748 shares of the Company's common
stock, respectively. Certain shareholders of Palouse and Sawtooth were also
officers and non-controlling shareholders of the Company. The Company accounted
for the transaction as a stock purchase and paid approximately $3.1 million and
$0.3 million of outstanding debt, including the debt to shareholders noted
above, of Palouse and Sawtooth, respectively.
 
  (b) General Cellular Corporation minority interest
 
     During 1995 the Company completed a cash redemption of the remaining common
stock shares (the "Redemption") of General Cellular Corporation's ("GCC"'), the
Company's predecessor company, common stock. As part of this Redemption, the
Company issued 896,210 shares of the Company's common stock for GCC common stock
in a one-for-one exchange. This redemption eliminated all minority interest
positions in the equity of GCC. The cost in excess of the carrying amounts of
the minority interests acquired increased licensing costs and other intangible
assets by approximately $11 million during 1995.
 
  (c) Stock issuances
 
     In January 1998, the Company issued 100,000 shares of its Class A Common
Stock pursuant to an Executive Restricted Stock Plan to certain key executives.
The vesting of these shares are subject to certain performance thresholds as
determined by the Board of Directors.
 
     In November 1997, the Company issued 3,888,888 shares of its Class A common
stock (approximately 5% of the outstanding capital stock of the Company) to a
subsidiary of Hutchison Telecommunications Limited ("HTL") for a purchase price
of approximately $74 million.
 
     In January 1997, the Company issued 95,000 shares of its Class A Common
Stock to certain key executives pursuant to an Executive Restricted Stock Plan.
The vesting of these shares are subject to certain performance thresholds as
determined by the Board of Directors.
 
     During 1996, 10,664,800 shares of common stock were issued and
approximately $233.9 million in net proceeds were received by the Company under
a registration statement of the Company's Class A Common Stock filed with the
SEC. Prior to this, the Company sold 88,567 shares of its common stock to an
officer of the Company at $11.29 per share for aggregate proceeds of
approximately $1.0 million.
 
     In November 1995, the Board of Directors approved an increase in the number
of authorized shares of the Company's common stock from 25 million to 300
million.
 
     During 1995, a wholly owned subsidiary issued 4,300,001 shares of Series A
Preferred Stock to certain existing shareholders of the Company at $35.00 per
share for aggregate proceeds of

approximately $150 million, which was comprised of approximately $14 million of
converted debt of shareholders and approximately $136 million in cash. The
preferred stock in the subsidiary was converted into common stock of the Company
on a one for 3.1 basis. Additionally, the Company sold 581,901 shares of common
stock at $11.29 per share for cash during 1995 to existing shareholders.
 
11. STOCK-BASED COMPENSATION PLANS
 
     On September 20, 1994, the Board of Directors of the Company established
the 1994 Management Incentive Stock Option Plan (the "MISOP") which was later
amended and approved, as amended, by the shareholders of the Company on November
16, 1995. The MISOP, 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.
 
     During 1996, the Board of Directors of the Company approved the 1996
Employee Stock Purchase Plan (the "ESPP") which became effective January 1,
1997, which 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 the Company 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 will be offered under this ESPP at 85% of market value at
each offer date. Participants are fully vested at all times.
 
     At December 31, 1997, 1996, and 1995 the Company 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, the Company's
net loss and basic loss per share would have increased to the pro forma amounts
indicated below:

     On October 31, 1997, the Company consummated the purchase of the cellular
business and assets of Triad 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 the Company's Class A Common Stock. The transaction was accounted for using
the purchase method of accounting. In accordance with its agreement with Triad,
the Company filed a shelf Registration Statement on Form S-3 covering future
resales of such shares. The Company also acquired from Triad certain D and E
Block PCS licenses for an aggregate purchase price of approximately $4.6
million, such amount being the aggregate amount Triad paid the FCC in its
successful bids for such licenses in the FCC's auction of such licenses.

     During 1996 and 1995 the Company acquired six cellular RSAs and one
cellular MSA throughout the western United States, respectively. The aggregate
cash paid for these transactions was $35.6 million and $38.6 million, in 1996
and 1995, respectively. All of these transactions were accounted for using the
purchase method of accounting. Six of the transactions were asset purchases
while one was a stock purchase in which the Company issued 217,000 shares of
common stock at $11.29 per share. Substantially all of the purchase price of
each acquisition was allocated to licensing costs.
 
     In June 1996, the Company purchased a Denver MTA PCS wireless license for
$66.1 million. This transaction was accounted for as an asset purchase.
 
  Exchanges
 
     In July 1995, the Company exchanged its cellular assets in certain
Minnesota markets, its ownership interests in three other markets and $3.0
million in cash for the cellular assets and license of the Lubbock, TX MSA
market. There was no gain or loss recognized on the transaction.
 
13. SEGMENT INFORMATION
 
     The Company's operations are classified into two principal reportable
segments: cellular and PCS. The Company provides cellular services in rural
markets and 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 costs and assets benefit all
of the Company's operations. These items are allocated to the segments in a
manner which reflects management's judgment as to the nature of the activity
causing those items to be incurred.

16. HUTCHISON TRANSACTION
 
     In addition to the shares issued by the Company to a subsidiary of HTL (as
discussed in Note 10) during the fourth quarter of 1997, the Company and its
subsidiary, Western PCS Corporation ("Western PCS"), entered into an agreement
with HTL and another subsidiary of HTL (the "HTL Sub") pursuant to which the HTL
Sub agreed to purchase 19.9% of Western PCS for an aggregate purchase price of
$248.4 million. In the first quarter of 1998, this purchase received a favorable
declaratory ruling by the FCC granting a waiver from the indirect foreign
ownership restrictions under the Communications Act of 1934, as amended; and the
expiration or early termination of all applicable waiting periods under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended has passed. The
Company and Western PCS have amended certain outstanding financing agreements to
which they are subject, and unless otherwise agreed to by HTL Sub and the
Company, neither the Company nor Western PCS shall have any liability regarding
any indebtedness of the other. The HTL Sub has designated two directors to a ten
person Board of Directors of Western PCS who have certain rights with respect to
certain transactions and actions of Western PCS. Western PCS and the Company
received $248.4 million in February 1998 upon closing of this transaction.

</TABLE>
 
     Under the terms and conditions of the U.S. Underwriting Agreement, the U.S.
Underwriters are committed to take and pay for all of the shares offered hereby,
if any are taken.
 
     The U.S. Underwriters propose to offer the shares of Class A Common Stock
in part directly to the public at the initial public offering price set forth on
the cover page of this Prospectus, and in part to certain securities dealers at
such price less a concession of $     per share. The U.S. Underwriters may
allow, and such dealers may reallow, a concession not in excess of $     per
share to certain brokers and dealers. After the shares of Class A Common Stock
are released for sale to the public, the offering price and other selling terms
may from time to time be varied by the representatives.
 
     The Company has and the Selling Shareholders have entered into an
underwriting agreement (the "International Underwriting Agreement") with the
underwriters of the international offering (the "International Underwriters")
providing for the concurrent offer and sale of        shares of Class A Common
Stock in the international offering outside the United States. The initial
public offering price and aggregate underwriting discounts and commissions per
share for the Offerings are identical. The closing of the offering made hereby
is a condition to the closing of the international offering, and vice versa. The
representatives of the International Underwriters are Goldman Sachs
International, Donaldson, Lufkin & Jenrette International, Merrill Lynch
International and Salomon Smith Barney International.
 
     Pursuant to an Agreement between the U.S. and International Underwriting
Syndicates (the "Agreement Between Syndicates") relating to the Offerings, each
of the U.S. Underwriters named herein has agreed that, as a part of the
distribution of the shares offered hereby and subject to certain exceptions, it
will offer, sell or deliver the shares offered hereby, directly or indirectly,
only in the United States of America (including the States and the District of
Columbia), its territories, its possessions and other areas subject to its
jurisdiction (the "United States") and to U.S. persons, which term shall mean,
for purposes of this paragraph: (a) any individual who is a resident of the
United States or (b) any corporation, partnership or other entity organized in
or under the laws of the United States or any political subdivision thereof and
whose office most directly involved with the purchase is located in the United
States. Each of the International Underwriters has agreed pursuant to the
Agreement Between Syndicates that, as a part of the distribution of the shares
offered as a part of the international offering, and subject to certain
exceptions, it will (i) not, directly or
 
                                       U-1
<PAGE>   86
 
indirectly, offer, sell or deliver shares of Class A Common Stock (a) in the
United States or to any U.S. persons or (b) to any persons whom it believes
intends to reoffer, resell or deliver the shares in the United States or to any
U.S. persons, and (ii) cause any dealer to whom it may sell such shares at any
concession to agree to observe a similar restriction.
 
     Pursuant to the Agreement Between Syndicates, sales may be made between the
U.S. Underwriters and the International Underwriters of such number of shares of
Class A Common Stock as may be mutually agreed. The price of any shares so sold
shall be the initial public offering price, less an amount not greater than the
selling concession.
 
     Certain Selling Shareholders have granted the U.S. Underwriters an option
exercisable for 30 days after the date of this Prospectus to purchase up to an
aggregate of        additional shares of Class A Common Stock solely to cover
over-allotments, if any, at the initial public offering price less the
underwriting discount, as set forth on the cover page of this Prospectus. If the
U.S. Underwriters exercise their over-allotment option, the U.S. Underwriters
have severally agreed, subject to certain conditions, to purchase approximately
the same percentage thereof that the number of shares to be purchased by each of
them, as shown in the foregoing table, bears to the        shares of Class A
Common Stock offered hereby. The U.S. Underwriters may exercise such option only
to cover over-allotments in connection with the sale of the        shares of
Class A Common Stock offered hereby. Certain Selling Shareholders have granted
the International Underwriters a similar option to purchase up to an aggregate
of        additional shares of Class A Common Stock.
 
     The Company, the Selling Shareholders, the Company's executive officers and
directors and certain other shareholders of the Company have agreed that, during
the period beginning from the date of this Prospectus and continuing to and
including the date 90 days after the date of this Prospectus, they will not
offer, sell, contract to sell or otherwise dispose of any securities of the
Company (other than, with respect to the Company, pursuant to employee stock
option plans existing on, or upon the conversion of exchange of convertible or
exchangeable securities outstanding as of, the date of this Prospectus) that are
substantially similar to the shares of Class A Common Stock or which are
convertible or exchangeable into securities which are substantially similar to
the shares of Class A Common Stock, without the prior written consent of the
representatives of the U.S. Underwriters, except for the shares of Class A
Common Stock offered in connection with the concurrent U.S. and international
offerings and certain gift transactions.
 
     This Prospectus may be used by underwriters and dealers in connection with
offers and sales of the Class A Common Stock to persons located in the United
States.
 
     The Class A Common Stock is listed on the Nasdaq Stock Market under the
symbol "WWCA."
 
     Settlement for the Class A Common Stock will be made in immediately
available funds, and all secondary trading will settle in immediately available
funds.
 
     In connection with the Offerings, the Underwriters may purchase and sell
the Class A Common Stock in the open market. These transactions may include
over-allotment and stablizing transactions and purchases to cover syndicate
short positions created in connection with the Offerings. Stablizing
transactions consist of certain bids or purchases for the purpose of preventing
or retarding a decline in the market price of the Class A Common Stock; and
syndicate short positions involve the sale by the Underwriters of a greater
number of shares than they are required to purchase from the Selling
Shareholders in the Offerings. The Underwriters also may impose a penalty bid,
whereby selling concessions allowed to syndicate members or other broker-dealers
in respect of the Class A Common Stock sold in the Offerings for their account
may be reclaimed by the syndicate if such shares are repurchased by the
syndicate in stablizing or covering transactions. These activities may
stabilize, maintain or otherwise affect the market price of the Class A Common
Stock, which may be higher than the price that might otherwise prevail in the
open market; and these
 
                                       U-2
<PAGE>   87
 
activities, if commenced, may be discontinued at any time. These transactions
may be effected on the Nasdaq National Market, in the over-the-counter market or
otherwise.
 
     Under Rule 2720 of the Conduct Rules of the National Association of
Securities Dealers, Inc. (the "NASD"), the Company may be deemed to be an
affiliate of Goldman Sachs. The Offerings are being conducted in accordance with
the requirements of Rule 2720. The Underwriters may not confirm sales to any
accounts over which they exercise discretionary authority without the prior
specific written approval of the customer.
 
     The Company and the Selling Shareholders have agreed to indemnify the
several Underwriters against certain liabilities, including liabilities under
the Securities Act.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Section 23B.08.510 of the Revised Code of Washington authorizes Washington
corporations to indemnify their officers and directors under certain
circumstances against expenses and liabilities incurred in legal proceedings
involving such persons because of their being or having been an officer or
director. The Company's Articles of Incorporation and Bylaws require
indemnification of the Company's officers and directors to the fullest extent
permitted by Washington law. The Company also maintains directors' and officers'
liability insurance.
 
     The Company's By-laws and Articles of Incorporation provide that the
Company shall, to the full extent permitted by the Washington Business
Corporation Act (the "Washington Business Act") of the State of Washington, as
amended from time to time, indemnify all directors and officers of the Company.
In addition, the Company's Articles of Incorporation contains a provision
eliminating the personal liability of directors to the Company or its
shareholders for monetary damages arising out of a breach of fiduciary duty.
Under Washington law, this provision eliminates the liability of a director for
breach of fiduciary duty but does not eliminate the personal liability of any
director for (i) acts or omissions of a director that involve intentional
misconduct or a knowing violation of law, (ii) conduct in violation of Section
23B.08.310 of the Revised Code of Washington (which section relates to unlawful
distributions) or (iii) any transaction from which a director personally
received a benefit in money, property or services to which the director was not
legally entitled.
 
     The Company has entered into separate indemnification agreements with each
of its directors and executive officers.
 
ITEM 16. LIST OF EXHIBITS
 
     The Exhibits to this registration statement are listed in the Index to
Exhibits on page II-4.
 
ITEM 17. UNDERTAKINGS
 
     The undersigned registrant hereby undertakes:
 
          (1) For purposes of determining any liability under the 1933 Act, each
     filing of the registrant's annual report pursuant to Section 13(a) or
     Section 15(d) of the Exchange Act (and, where applicable, each filing of an
     employee benefit plan's annual report pursuant to Section 15(d) of the
     Exchange Act) that is incorporated by reference in the registration
     statement shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.
 
          (2) Insofar as indemnification for liabilities arising under the
     Securities Act of 1933 Act may be permitted to directors, officers and
     controlling persons of the registrant pursuant to the foregoing provisions,
     or otherwise, the registrant has been advised that in the opinion of the
     Securities and Exchange Commission such indemnification is against public
     policy as
                                      II-1
<PAGE>   90
 
     expressed in the 1933 Act and is, therefore, unenforceable. In the event
     that a claim for indemnification against such liabilities (other than the
     payment by the registrant of expenses incurred or paid by a director,
     officer or controlling person of the registrant in the successful defense
     of any action, suit or proceeding) is asserted by such director, officer or
     controlling person in connection with the securities being registered, the
     registrant will, unless in the opinion of its counsel the matter has been
     settled by controlling precedent, submit to a court of appropriate
     jurisdiction the question whether such indemnification by it is against
     public policy as expressed in the Act and will be governed by the final
     adjudication of such issue.

                      UNDERWRITING AGREEMENT (U.S. VERSION)

                                                                  April __, 1998


Goldman, Sachs & Co.,
[Name(s) of Co-Representative(s)]
 As representatives of the several Underwriters
    named in Schedule I hereto,
c/o Goldman, Sachs & Co.,
85 Broad Street,
New York, New York 10004.

Ladies and Gentlemen:

        Certain shareholders named in Schedule II hereto (the "Selling
Shareholders") of Western Wireless Corporation, a Washington corporation (the
"Company"), propose, subject to the terms and conditions stated herein, to sell
to the Underwriters named in Schedule I hereto (the "Underwriters") an aggregate
of ____ shares (the "Firm Shares") and, at the election of the Underwriters, up
to ___ additional shares (the "Optional Shares") of Class A Common Stock, no par
value per share ("Stock"), of the Company (the Firm Shares and the Optional
Shares that the Underwriters elect to purchase pursuant to Section 2 hereof are
herein collectively called the "Shares").

        It is understood and agreed to by all parties that the Company and the
Selling Shareholders are concurrently entering into an agreement (the
"International Underwriting Agreement") providing for the sale by the Selling
Shareholders of up to a total of _______ shares of Stock (the "International
Shares"), including the overallotment option thereunder, through arrangements
with certain underwriters outside the United States (the "International
Underwriters"), for whom Goldman Sachs International,
____________________________ , and _________________________________ are acting
as lead managers. Anything herein or therein to the contrary notwithstanding,
the respective closings under this Agreement and the International Underwriting
Agreement are hereby expressly made conditional on one another. The Underwriters
hereunder and the International Underwriters are simultaneously entering into an
Agreement between U.S. and International Underwriting Syndicates (the "Agreement
between Syndicates") which provides, among other things, for the transfer of
shares of Stock between the two syndicates. Two forms of prospectus are to be
used in connection with the offering and sale of shares of Stock contemplated by
the foregoing, one relating to the Shares hereunder and the other relating to
the International Shares. The latter form of prospectus will be identical to the
former except for certain substitute pages. Except as used in Sections 2, 3, 4,
9 and 11 herein, and except as the context may otherwise require, references
hereinafter to the Shares shall include all the shares of Stock which may be
sold pursuant to either this Agreement or the International Underwriting
Agreement, and references herein to any

prospectus whether in preliminary or final form, and whether as amended or
supplemented, shall include both the U.S. and international versions thereof.

        1. (a) The Company represents and warrants to, and agrees with, each of
the Underwriters that:

            (i) A registration statement on Form S-3 (File No. 333-____) (the
       "Initial Registration Statement") in respect of the Shares has been filed
       with the Securities and Exchange Commission (the "Commission"); the
       Initial Registration Statement and any post-effective amendment thereto,
       each in the form heretofore delivered to you, and, excluding exhibits
       thereto but including all documents incorporated by reference in the
       prospectus contained therein, to you for each of the other Underwriters,
       have been declared effective by the Commission in such form; other than a
       registration statement, if any, increasing the size of the offering (a
       "Rule 462(b) Registration Statement"), filed pursuant to Rule 462(b)
       under the Securities Act of 1933, as amended (the "Act"), which became
       effective upon filing, no other document with respect to the Initial
       Registration Statement or document incorporated by reference therein has
       heretofore been filed with the Commission; and no stop order suspending
       the effectiveness of the Initial Registration Statement, any
       post-effective amendment thereto or the Rule 462(b) Registration
       Statement, if any, has been issued and no proceeding for that purpose has
       been initiated or threatened by the Commission (any preliminary
       prospectus included in the Initial Registration Statement or filed with
       the Commission pursuant to Rule 424(a) of the rules and regulations of
       the Commission under the Act is hereinafter called a "Preliminary
       Prospectus"; the various parts of the Initial Registration Statement and
       the Rule 462(b) Registration Statement, if any, including all exhibits
       thereto and including (i) the information contained in the form of final
       prospectus filed with the Commission pursuant to Rule 424(b) under the
       Act in accordance with Section 5(a) hereof and deemed by virtue of Rule
       430A under the Act to be part of the Initial Registration Statement at
       the time it was declared effective or such part of the Rule 462(b)
       Registration Statement, if any, became or hereafter becomes effective and
       (ii) the documents incorporated by reference in the prospectus contained
       in the Initial Registration Statement at the time such part of the
       Initial Registration Statement became effective, in each of clause (i)
       and (ii) each as amended at the time such part of the Initial
       Registration Statement became effective, are hereinafter collectively
       called the "Registration Statement"; such final prospectus in the form
       first filed pursuant to Rule 424(b) under the Act, is hereafter called
       the "Prospectus"); and any reference herein to any Preliminary Prospectus
       or the Prospectus shall be deemed to refer to and include the documents
       incorporated by reference therein pursuant to Item 12 of Form S-3 under
       the Act, as of the date of such Preliminary Prospectus or Prospectus, as
       the case may be; any reference to any amendment or supplement to any
       Preliminary Prospectus or the Prospectus shall be deemed to refer to and
       include any documents filed after the date of such Preliminary Prospectus
       or Prospectus, as the case may be, under the Securities Exchange Act of
       1934, as amended (the "Exchange Act"), and incorporated by reference in
       such Preliminary Prospectus or Prospectus, as the case may be; and any
       reference to any amendment to the Registration Statement shall be deemed
       to refer to and include any annual report of the Company filed pursuant
       to Section 13(a) or 15(d) of the Exchange Act after the effective date of
       the Initial Registration Statement that is incorporated by reference in
       the Registration Statement);

<PAGE>   3



           (ii) No order preventing or suspending the use of any Preliminary
       Prospectus has been issued by the Commission, and each Preliminary
       Prospectus, at the time of filing thereof, conformed in all material
       respects to the requirements of the Act and the rules and regulations of
       the Commission thereunder, and did not contain an untrue statement of a
       material fact or omit to state a material fact required to be stated
       therein or necessary to make the statements therein, in the light of the
       circumstances under which they were made, not misleading; provided,
       however, that this representation and warranty shall not apply to any
       statements or omissions made in reliance upon and in conformity with
       information furnished in writing to the Company by an Underwriter through
       Goldman, Sachs & Co. expressly for use therein or by a Selling
       Shareholder expressly for use in the preparation of the answers therein
       to Item 7 of Form S-3;

          (iii) The documents incorporated by reference in the Prospectus, when
       they became effective or were filed with the Commission, as the case may
       be, conformed in all material respects to the requirements of the Act or
       the Exchange Act, as applicable, and the rules and regulations of the
       Commission thereunder, and none of such documents contained an untrue
       statement of a material fact or omitted to state a material fact required
       to be stated therein or necessary to make the statements therein not
       misleading; and any further documents so filed and incorporated by
       reference in the Prospectus or any further amendment or supplement
       thereto, when such documents become effective or are filed with the
       Commission, as the case may be, will conform in all material respects to
       the requirements of the Act or the Exchange Act, as applicable, and the
       rules and regulations of the Commission thereunder and will not contain
       an untrue statement of a material fact or omit to state a material fact
       required to be stated therein or necessary to make the statements therein
       not misleading; provided, however, that this representation and warranty
       shall not apply to any statements or omissions made in reliance upon and
       in conformity with information furnished in writing to the Company by an
       Underwriter through Goldman, Sachs & Co. expressly for use therein;

           (iv) The Registration Statement conforms, and the Prospectus and any
       further amendments or supplements to the Registration Statement or the
       Prospectus will conform, in all material respects to the requirements of
       the Act and the rules and regulations of the Commission thereunder and do
       not and will not, as of the applicable effective date as to the
       Registration Statement and any amendment thereto and as of the applicable
       filing date as to the Prospectus and any amendment or supplement thereto,
       contain an untrue statement of a material fact or omit to state a
       material fact required to be stated therein or necessary to make the
       statements therein not misleading; provided, however, that this
       representation and warranty shall not apply to any statements or
       omissions made in reliance upon and in conformity with information
       furnished in writing to the Company by an Underwriter through Goldman,
       Sachs & Co. expressly for use therein or by a Selling Shareholder
       expressly for use in the preparation of the answers therein to Item 7 of
       Form S-3;

            (v) Neither the Company nor any of its subsidiaries has sustained
       since the date of the latest audited financial statements included or
       incorporated by reference in the Prospectus any material loss or
       interference with its business from fire, explosion, flood or other
       calamity, whether or not covered by insurance, or from any labor dispute
       or court or governmental action, order or decree, otherwise than as set
       forth or



                                       3

       which information is given in the Registration Statement and the
       Prospectus, there has not been any change in the capital stock or
       partnership interests and there has not been any increase in the

       general affairs, management, financial position, shareholders' equity or
       results of operations of the Company and its subsidiaries (a "Material
       Adverse Effect"), otherwise than as set forth or contemplated in the

           (vi) The Company and its subsidiaries have valid title in fee simple
       to all real property and valid title to all personal property owned by
       them, in each case free and clear of all liens, encumbrances and defects
       except those that are described in the Prospectus, those that could not
       reasonably be expected to have a Material Adverse Effect and those that
       do not interfere with the use made and proposed to be made of such
       property by the Company and its subsidiaries; and any real property and
       buildings held under lease by the Company and its subsidiaries are held
       by them under valid, subsisting and enforceable leases with such
       exceptions as could not reasonably be expected to have a Material Adverse

       such property and buildings by the Company and its subsidiaries;

          (vii) The Company has been duly incorporated and is validly existing

       may be) has been duly incorporated and is validly existing as a
       corporation in good standing under the laws of its jurisdiction of
       incorporation;

         (viii) The Company has an authorized capitalization as set forth in the

       contained in the Prospectus; and all of the issued shares of capital
       stock or partnership interests of each Significant Subsidiary of the
       Company have been duly and validly authorized and issued, are fully paid

       Agreement and the International Underwriting Agreement and the
       consummation of the transactions herein and therein contemplated will not
       conflict with or result in a breach or violation of any of the terms or
       provisions of, or constitute a default under, any indenture, mortgage,
       deed of trust, loan agreement, shareholders agreement, registration
       rights agreement or other material agreement or instrument to which the
       Company or any of its subsidiaries is a party or by which the Company or
       any of its subsidiaries is bound or to which any of the property or

       Incorporation or By-laws of the Company or any statute or any order, rule
       or regulation of any court or governmental agency or body having
       jurisdiction over the Company or any of its subsidiaries or any of their
       properties; and no consent, approval, authorization, order, registration
       or qualification of or with any such court or governmental agency or body
       is required for the sale of the Shares or the consummation by the Company

       qualifications as may be required under state or foreign securities or
       Blue Sky laws in connection with the purchase and distribution of the
       Shares by the Underwriters and the International Underwriters;

            (x) Neither the Company nor any of its Significant Subsidiaries is
       (a) in violation of its Articles or Certificate of Incorporation, as the
       case may be, or By-laws or (b) in default in the performance or
       observance of any material obligation, agreement, covenant or condition
       contained in any indenture, mortgage, deed of trust, loan agreement,
       lease, shareholders agreement, registration rights agreement or other
       agreement or instrument to which it is a party or by which it or any of
       its properties may be bound, except, in the case of this clause (b), for
       defaults that individually or in the aggregate would not have a Material
       Adverse Effect;

           (xi) The statements set forth in the Prospectus under the caption
       "Description of Capital Stock," insofar as they purport to constitute a
       summary of the terms of the Stock and the Class B Common Stock, and under
       the captions "Underwriting," "Risk Factors--Competition," "--Intellectual
       Property and Branding," "--Governmental Regulation," "Description of
       Indebtedness," "Business--Competition" and "Business--Governmental
       Regulation" insofar as they purport to describe the provisions of the
       laws and documents to which the Company or any subsidiary is a party
       referred to therein are accurate, complete and fair in all material
       respects;

          (xii) Other than as set forth or contemplated in the Prospectus, there
       are no legal or governmental proceedings pending to which the Company or
       any of its subsidiaries is a party or of which any property of the
       Company or any of its subsidiaries is the subject which, if determined
       adversely to the Company or any of its subsidiaries, would individually
       or in the aggregate have a material adverse effect on the current or
       future consolidated financial position, shareholders' equity or results
       of operations of the Company and its subsidiaries taken as a whole; and,
       to the best of the Company's knowledge, no such proceedings are
       threatened or contemplated by governmental authorities or threatened by
       others;

       "controlled" by an "investment company," as such terms are defined in the
       Investment Company Act of 1940, as amended (the "Investment Company
       Act");

          (xiv) Arthur Andersen LLP, who have certified certain financial
       statements of the Company and its subsidiaries, are independent public
       accountants as required by the Act and the rules and regulations of the

       ("Permits"), including Permits issued by the Federal Communications
       Commission (the "FCC"), as are necessary to own their respective
       properties and to conduct their respective businesses substantially in
       the manner described in the Prospectus, except for any such Permits the
       absence of which could not reasonably be expected to result in a Material
       Adverse Effect; the Company and its subsidiaries have fulfilled all their
       material obligations with respect to such Permits and no event has
       occurred which allows (or after notice or lapse of time would allow)
       revocation or termination thereof or results in any other material
       impairment of the rights of the holder of any such Permit, in each case
       which could reasonably be expected to result in a Material Adverse
       Effect; and, except as described in the Prospectus, none of such Permits
       contains any restriction that is burdensome to the Company or any of its
       subsidiaries, except for restrictions that could not reasonably be
       expected to have a Material Adverse Effect; and

       registrations, service marks, service mark registrations, trade names,
       licenses relating to intellectual property, trade secrets and rights
       ("Intellectual Property") described in the Prospectus as being owned or
       possessed by them or any of them, and the Company is not aware of any
       claim to the contrary or any challenge by any other person to the rights
       of the Company or any of its subsidiaries with respect to the foregoing,
       which claim or challenge could reasonably be expected to have a Material
       Adverse Effect.

represents and warrants to, and agrees with, each of the Underwriters and the
Company that:

       Shares to be sold by such Selling Shareholder hereunder and under the
       International Underwriting Agreement, have been obtained; and such
       Selling Shareholder has full right, power and authority to enter into
       this Agreement, the International Underwriting Agreement, the Custody
       Agreement and Power of Attorney and to sell, assign, transfer and deliver
       the Shares to be sold by such Selling Shareholder hereunder and under the
       International Underwriting Agreement;

       breach or violation of any of the terms or provisions of, or constitute a
       default under any indenture, mortgage, deed of trust, loan agreement,
       shareholders agreement, registration rights agreement or other material
       agreement or instrument to which such Selling Shareholder is a party or
       by which such Selling Shareholder is bound, or to which any of the
       property or assets of such Selling Shareholder is subject, nor will such
       action result in any violation of the provisions of the Articles or
       Certificate of Incorporation, as the case may be, or By-laws of such
       Selling Shareholder if such Selling Shareholder is a corporation, the
       Partnership Agreement of such Selling Shareholder if such Selling
       Shareholder is a partnership, or any statute or any order, rule or
       regulation of any court or governmental agency or body having

       will have, valid title to the Shares to be sold by such Selling
       Shareholder hereunder and under the International Underwriting Agreement,
       free and clear of all liens, encumbrances, equities or claims; and, upon
       delivery of such Shares and payment therefor pursuant hereto and thereto,
       valid title to such Shares, free and clear of all liens, encumbrances,
       equities or claims, will pass to the several Underwriters or the
       International Underwriters, as the case may be;

           (iv) During the period beginning from the date hereof and continuing
       to and including the date 90 days after the date of the Prospectus, not
       to offer, sell, contract to sell or otherwise dispose of, except as
       provided hereunder or under the International Underwriting Agreement, any
       securities of the Company that are substantially similar to the Shares,
       including but not limited to any securities that are convertible into or
       exchangeable for, or that represent the right to receive, Stock or any
       such substantially similar securities (other than pursuant to employee
       stock option plans existing on, or upon the conversion or exchange of
       convertible or exchangeable securities outstanding as of, the date of
       this Agreement), except (a) as a gift or gifts, provided the donee or
       donees thereof agree to be bound by this restriction, or (b) with the
       prior written consent of the representatives of the Underwriters;

            (v) Such Selling Shareholder has not taken and will not take,
       directly or indirectly, any action which is designed to or which has
       constituted or which might reasonably be expected to cause or result in
       stabilization or manipulation of the price of any security of the Company
       to facilitate the sale or resale of the Shares;

           (vi) To the extent that any statements or omissions made in the
       Registration Statement, any Preliminary Prospectus, the Prospectus or any
       amendment or supplement thereto are made in reliance upon and in
       conformity with written information furnished to the Company by such
       Selling Shareholder expressly for use therein, such Preliminary
       Prospectus and the Registration Statement did, and the Prospectus and any
       further amendments or supplements to the Registration Statement



                                       7

       and the Prospectus, when they become effective or are filed with the
       Commission, as the case may be, will conform in all material respects to
       the requirements of the Act and the rules and regulations of the
       Commission thereunder and will not contain any untrue statement of a
       material fact or omit to state any material fact required to be stated
       therein or necessary to make the statements therein not misleading;

          (vii) In order to document the Underwriters' compliance with the

       extent set forth therein are irrevocable; the obligations of the Selling
       Shareholders hereunder shall not be terminated by operation of law,
       whether by the death or incapacity of any individual Selling Shareholder
       or, in the case of an estate or trust, by the death or incapacity of any
       executor or trustee or the termination of such estate or trust, or in the
       case of a partnership or corporation, by the dissolution of such
       partnership or corporation, or by the occurrence of any other event; if
       any individual Selling Shareholder or any such executor or trustee should
       die or become incapacitated, or if any such estate or trust should be
       terminated, or if any such partnership or corporation should be
       dissolved, or if any other such event should occur, before the delivery
       of the Shares hereunder, certificates representing the Shares shall be

       the terms and conditions of this Agreement, of the International
       Underwriting Agreement and of the Custody Agreement

       and Power of Attorney; and actions taken by the Attorneys-in-Fact
       pursuant to the Custody Agreement and Power of Attorney shall be as valid
       as if such death, incapacity, termination, dissolution or other event had
       not occurred, regardless of whether or not the Custodian, the
       Attorneys-in-Fact, or any of them, shall have received notice of such
       death, incapacity, termination, dissolution or other event.

        2. Subject to the terms and conditions herein set forth, (a) each of the
Selling Shareholders agrees, severally and not jointly, to sell to each of the
Underwriters, and each of the Underwriters agrees, severally and not jointly, to
purchase from each of the Selling Shareholders, at a purchase price per share of
$___________, the number of Firm Shares (to be adjusted by you so as to
eliminate fractional shares) determined by multiplying the aggregate number of
Firm Shares to be sold by each of the Selling Shareholders as set forth opposite
their respective names in Schedule II hereto by a fraction, the numerator of
which is the aggregate number of Firm Shares to be purchased by such Underwriter
as set forth opposite the name of such Underwriter in Schedule I hereto and the
denominator of which is the aggregate number of Firm Shares to be purchased by
all of the Underwriters from all of the Selling Shareholders hereunder and (b)
in the event and to the extent that the Underwriters shall exercise the election
to purchase Optional Shares as provided below, each of the Selling Shareholders
agrees, severally and not jointly, to sell to each of the Underwriters, and each
of the Underwriters agrees, severally and not jointly, to purchase from each of
the Selling Shareholders, at the purchase price per share set forth in clause
(a) of this Section 2, that portion of the number of Optional Shares as to which
such election shall have been exercised (to be adjusted by you so as to
eliminate fractional shares) determined by multiplying such number of Optional
Shares by a fraction, the numerator of which is the maximum number of Optional
Shares which such Underwriter is entitled to purchase as set forth opposite the
name of such Underwriter in Schedule I hereto and the denominator of which is
the maximum number of Optional Shares that all of the Underwriters are entitled
to purchase hereunder.

        The Selling Shareholders, as and to the extent indicated in Schedule II
hereto, hereby grant, severally and not jointly, to the Underwriters the right
to purchase at their election up to _________ Optional Shares, at the purchase
price per share set forth in the paragraph above, for the sole purpose of
covering overallotments in the sale of the Firm Shares. Any such election to
purchase Optional Shares shall be made in proportion to the number of Optional
Shares to be sold by each Selling Shareholder. Any such election to purchase
Optional Shares may be exercised by written notice from you to the
Attorneys-in-Fact, given within a period of 30 calendar days after the date of
this Agreement and setting forth the aggregate number of Optional Shares to be
purchased and the date on which such Optional Shares are to be delivered, as
determined by you but in no event earlier than the First Time of Delivery (as
defined in Section 4 hereof) or, unless you and the Attorneys-in-Fact otherwise
agree in writing, earlier than two or later than ten business days after the
date of such notice.

        3. Upon the authorization by you of the release of the Firm Shares, the
several Underwriters propose to offer the Firm Shares for sale upon the terms
and conditions set forth in the Prospectus.

        4. (a) The Shares to be purchased by each Underwriter hereunder, in

Underwriter, against payment by or on behalf of such Underwriter of the purchase
price therefor by wire transfer of Federal (same-day) funds to the account
specified by each of the Selling Shareholders, as their interests may appear, to
Goldman, Sachs & Co. at least forty-eight hours in advance. The Company will
cause the certificates representing the Shares to be made available for checking

custodian (the "Designated Office"). The time and date of such delivery and
payment shall be, with respect to the Firm Shares, 9:30 a.m., New York City
time, on April __, 1998 or such other time and date as Goldman, Sachs & Co. and
the Selling Shareholders may agree upon in writing, and, with respect to the
Optional Shares, 9:30 a.m., New York time, on the date specified by Goldman,
Sachs & Co. in the written notice given by Goldman, Sachs & Co. of the
Underwriters' election to purchase such Optional Shares, or such other time and
date as Goldman, Sachs & Co. and the Selling Shareholders may agree upon in
writing. Such time and date for delivery of the Firm Shares is herein called the
"First Time of Delivery," such time and date for delivery of the Optional
Shares, if not the First Time of Delivery, is herein called the "Second Time of
Delivery," and each such time and date for delivery is herein called a "Time of
Delivery".

        (b) The documents to be delivered at each Time of Delivery by or on
behalf of the parties hereto pursuant to Section 7 hereof, including the cross
receipt for the Shares and any additional documents requested by the
Underwriters pursuant to Section 7(n) hereof, will be delivered at the offices
of Preston Gates & Ellis, 701 Fifth Avenue, Seattle, Washington 98104-7078 (the

all at such Time of Delivery. A meeting will be held at the Closing Location at
1:00 p.m., Seattle time, on the New York Business Day next preceding such Time
of Delivery, at which meeting the final drafts of the documents to be delivered
pursuant to the preceding sentence will be available for review by the parties
hereto. For the purposes of this Section 4, "New York Business Day" shall mean

banking institutions in New York are generally authorized or obligated by law or
executive order to close.

        5. The Company agrees with each of the Underwriters:

qualification of the Shares for offering or sale in any jurisdiction, of the
initiation or threatening of any proceeding for any such purpose, or of any
request by the Commission for the amending or supplementing of the Registration

that in connection therewith the Company shall not be required to qualify as a
foreign corporation or to file a general consent to service of process in any

is required at any time in connection with the offering or sale of the Shares
and if at such time any events shall have occurred as a result of which the
Prospectus as then amended or supplemented would include an untrue statement of
a material fact or omit to state any material fact necessary in order to make
the statements therein, in the light of the circumstances under which they were
made when such Prospectus is delivered, not misleading, or, if for any other
reason it shall be necessary to amend or supplement the Prospectus or to file
under the Exchange Act any document incorporated by reference in the Prospectus
in order to comply with the Act or the Exchange Act, to notify you and upon your
request to file such document and to prepare and furnish without charge to each
Underwriter and to any dealer in securities as many copies as you may reasonably
request of an amended Prospectus or a supplement to the Prospectus which will
correct such statement or omission or effect such compliance, and in case any
Underwriter is required to deliver a prospectus in connection with sales of any
of the Shares at any time nine months or more after the time of issue of the
Prospectus, upon your request but at the expense of such Underwriter, to prepare

pursuant to employee stock option plans existing on, or upon the conversion or
exchange of convertible or exchangeable securities outstanding as of, the date
of this Agreement), without your prior written consent;

        (f) To furnish to its shareholders as soon as practicable after the end
of each fiscal year an annual report (including a balance sheet and statements

consolidated subsidiaries certified by independent public accountants) and, as

         pending to which the Company or any of its subsidiaries is a party or

         terms or provisions of, or constitute a default under, any indenture,
         mortgage, deed of trust, loan agreement, shareholders agreement,
         registration rights agreement or other material agreement or instrument
         known to such counsel to which the Company or any of its subsidiaries
         is a party or by which the Company or any of its subsidiaries is bound

         Company or any statute or any order, rule or regulation known to such
         counsel of any court or governmental agency or body having jurisdiction
         over the Company or any of its subsidiaries or any of their properties;

           (viii) No consent, approval, authorization, order, registration or

         the Shares or the consummation by the Company of the transactions
         contemplated by this Agreement and the International Underwriting
         Agreement, except the registration under the Act of the Shares, and
         such consents, approvals, authorizations, registrations or

         observance of any material obligation, agreement, covenant or condition
         contained in any indenture, mortgage, deed of trust, loan agreement,
         lease, shareholders agreement, registration rights agreement or other
         agreement or instrument, which such agreement or instrument is known to
         such counsel, to which it is a party or by which it or any of its
         properties may be bound, except, in the case of this clause (b), for
         defaults that individually or in the aggregate would not have a
         Material Adverse Effect;

            (x) The statements set forth in the Prospectus under the caption
         "Description of Capital Stock," insofar as they purport to constitute a
         summary of the terms of the Stock and the Class B Common Stock, and
         under the captions "Description of Indebtedness" and "Underwriting,"
         insofar as they purport to describe the provisions of the laws and

         "controlled" by an "investment company," as such terms are defined in
         the Investment Company Act;

          (xii) The documents incorporated by reference in the Prospectus or any
         further amendment or supplement thereto made by the Company prior to
         the Time of Delivery (other than the financial statements and related
         schedules therein, as to which such counsel need express no opinion),
         when they became effective or were filed with the Commission, as the
         case may be, complied as to form in all material respects with the



                                       15

         requirements of the Act or the Exchange Act, as applicable, and the
         rules and regulations of the Commission thereunder; and they have no
         reason to believe that any of such documents, when such documents
         became effective or were so filed, as the case may be, contained, in
         the case of a registration statement which became effective under the
         Act, an untrue statement of a material fact or omitted to state a
         material fact required to be stated therein or necessary to make the
         statements therein not misleading, or, in the case of other documents
         which were filed under the Exchange Act with the Commission, an untrue
         statement of a material fact or omitted to state a material fact
         necessary in order to make the statements therein, in the light of the
         circumstances under which they were made when such documents were so
         filed, not misleading; and

           (xiii) The Registration Statement and the Prospectus and any further
         amendments and supplements thereto made by the Company prior to such
         Time of Delivery (other than the financial statements and related

         need express no opinion) comply as to form in all material respects
         with the requirements of the Act and the rules and regulations
         thereunder, although they do not assume any responsibility for the
         accuracy, completeness or fairness of the statements contained in the
         Registration Statement or the Prospectus, except for those referred to
         in the opinion in subsection (x) of this Section 7(c).

                 In addition, such counsel shall state that nothing has come to
         their attention that would cause them to believe that, as of its
         effective date, the Registration Statement or any further amendment
         thereto made by the Company prior to such Time of Delivery (other than
         the financial statements and related schedules or other financial data
         therein, as to which such counsel need express no belief) contained an
         untrue statement of a material fact or omitted to state a material fact
         required to be stated therein or necessary to make the statements
         therein not misleading or that, as of its date, the Prospectus or any

         such Time of Delivery (other than the financial statements and related
         schedules or other financial data therein, as to which such counsel
         need express no belief) contained an untrue statement of a material
         fact or omitted to state a material fact necessary to make the
         statements therein, in the light of the circumstances under which they
         were made, not misleading or that, as of such Time of Delivery, either
         the Registration Statement or the Prospectus or any further amendment
         or supplement thereto made by the Company prior to such Time of
         Delivery (other than the financial statements and related schedules or
         other financial data therein, as to which such counsel need express no
         belief) contains an untrue statement of a material fact or omits to
         state a material fact necessary to make the statements therein, in the
         light of the circumstances under which they were made, not misleading;
         and they do not know of any amendment to the Registration Statement
         required to be filed or of any contracts or other documents of a
         character required to be filed as an exhibit to the Registration
         Statement or required to be incorporated by reference into the
         Prospectus or required to be described in the Registration Statement or

lease by the Company and its subsidiaries are held by them under valid,
subsisting and enforceable leases with such exceptions as could not reasonably
be expected to have a Material Adverse Effect;

subsidiaries, otherwise than as set forth or contemplated in the Prospectus, the
effect of which, in any such case described in Clause (i) or (ii), is in the
judgment of the Representatives so material and adverse as to make it
impracticable or inadvisable to proceed with the public offering or the delivery
of the Shares being delivered at such Time of Delivery on the terms and in the
manner contemplated in the Prospectus;

     (i) On or after the date hereof (i) no downgrading shall have occurred in
the rating according the Company's debt securities by any "national recognized
statistical rating organization", as that term is defined by the Commission for
purposes of Rule 436(g)(2) under the Act, and (ii) no such organization shall
have publicly announced that it has under surveillance or review, with possible
negative implications, its rating of any of the Company's debt securities.

     (j) On or after the date hereof there shall not have occurred any of the
following: (i) a suspension or material limitation in trading in securities
generally on the New York Stock Exchange or on NASDAQ; (ii) a suspension or
material limitation in trading in the Company's securities on NASDAQ; (iii) a
general moratorium on commercial banking activities declared



                                       19

by either Federal or New York or Washington State authorities; or (iv) the
outbreak or escalation of hostilities involving the United States or the
declaration by the United States of a national emergency or war, if the effect
of any such event specified in this Clause (iv) in the judgment of the
Representatives makes it impracticable or inadvisable to proceed with the public
offering or the delivery of the Shares being delivered at such Time of Delivery
on the terms and in the manner contemplated in the Prospectus;

     (k) The Shares to be sold by the Selling Shareholders at the Time of
Delivery shall have been duly listed for quotation on NASDAQ;

     (l) The Company has obtained and delivered to the Underwriters executed
copies of an agreement from each of the shareholders listed on Schedule III
substantially to the effect set forth in Section 5(e) hereof in form and
substance satisfactory to you;

     (m) The Company shall have complied with the provisions of Section 5(c)
hereof with respect to the furnishing of prospectuses on the New York Business
Day next succeeding the date of this Agreement; and

     (n) The Company and each of the Selling Shareholders shall have furnished
or caused to be furnished to you at such Time of Delivery certificates of
officers of the Company and of the Selling Shareholders, respectively,
satisfactory to you as to the accuracy of the representations and warranties of
the Company and each of the Selling Shareholders, respectively, herein at and as
of such Time of Delivery, as to the performance by the Company and each of the
Selling Shareholders of all of their respective obligations hereunder to be
performed at or prior to such Time of Delivery, and as to such other matters as
you may reasonably request, and the Company shall have furnished or caused to be
furnished certificates as to the matters set forth in subsections (a) and (h) of
this Section, and as to such other matters as you may reasonably request.

     8. (a) The Company will indemnify and hold harmless each Underwriter
against any losses, claims, damages or liabilities, joint or several, to which
such Underwriter may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon an untrue statement or alleged untrue statement of a
material fact contained in any Preliminary Prospectus, the Registration
Statement or the Prospectus, or any amendment or supplement thereto, or arise
out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and will reimburse each Underwriter for any legal or
other expenses reasonably incurred by such Underwriter in connection with
investigating or defending any such action or claim as such expenses are
incurred; provided, however, that the Company shall not be liable in any such
case to the extent that any such loss, claim, damage or liability arises out of
or is based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in any Preliminary Prospectus, the Registration Statement
or the Prospectus or any such amendment or supplement in reliance upon and in
conformity with written information furnished to the Company by any Underwriter
through Goldman, Sachs & Co. expressly for use therein.

     (b) Each of the Selling Shareholders severally and not jointly will
indemnify and hold harmless each Underwriter against any losses, claims, damages
or liabilities, joint or several, to which such Underwriter may become subject,
under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based



                                       20

<PAGE>   21

upon an untrue statement or alleged untrue statement of a material fact
contained in any Preliminary Prospectus, the Registration Statement or the
Prospectus, or any amendment or supplement thereto, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
in each case to the extent, but only to the extent, that such untrue statement
or alleged untrue statement or omission or alleged omission was made in any
Preliminary Prospectus, the Registration Statement or the Prospectus or any such
amendment or supplement in reliance upon and in conformity with written
information furnished to the Company by such Selling Stockholder expressly for
use therein; and will reimburse each Underwriter for any legal or other expenses
reasonably incurred by such Underwriter in connection with investigating or
defending any such action or claim as such expenses are incurred; provided,
however, that such Selling Stockholder shall not be liable in any such case to
the extent that any such loss, claim, damage or liability arises out of or is
based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in any Preliminary Prospectus, the Registration Statement
or the Prospectus or any such amendment or supplement in reliance upon and in
conformity with written information furnished to the Company by any Underwriter
through Goldman, Sachs & Co. expressly for use therein; provided, further, that
the liability of a Selling Shareholder pursuant to this subsection (b) shall not
exceed the product of the number of Shares sold by such Selling Shareholder and
the public offering price of the Shares as set forth in the Prospectus.

     (c) Each Underwriter will indemnify and hold harmless the Company and each
Selling Shareholder against any losses, claims, damages or liabilities, joint or
several, to which the Company or such Selling Shareholder may become subject,
under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in any
Preliminary Prospectus, the Registration Statement or the Prospectus, or any
amendment or supplement thereto, or arise out of or are based upon the omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, in each case
to the extent, but only to the extent, that such untrue statement or alleged
untrue statement or omission or alleged omission was made in any Preliminary
Prospectus, the Registration Statement or the Prospectus or any such amendment
or supplement in reliance upon and in conformity with written information
furnished to the Company by such Underwriter through Goldman, Sachs & Co.
expressly for use therein; and will reimburse the Company and each Selling
Shareholder for any legal or other expenses reasonably incurred by the Company
or such Selling Shareholder in connection with investigating or defending any
such action or claim as such expenses are incurred.

     (d) Promptly after receipt by an indemnified party under subsection (a),
(b) or (c) above of notice of the commencement of any action, such indemnified
party shall, if a claim in respect thereof is to be made against an indemnifying
party under such subsection, notify the indemnifying party in writing of the
commencement thereof; but the omission so to notify the indemnifying party shall
not relieve it from any liability which it may have to any indemnified party
otherwise than under such subsection. In case any such action shall be brought
against any indemnified party and it shall notify the indemnifying party of the
commencement thereof, the indemnifying party shall be entitled to participate
therein and, to the extent that it shall wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with
counsel satisfactory to such indemnified party (who shall not, except with the
consent of the indemnified party, be counsel to the indemnifying party), and,
after notice from



                                       21

<PAGE>   22

the indemnifying party to such indemnified party of its election so to assume
the defense thereof, the indemnifying party shall not be liable to such
indemnified party under such subsection for any legal expenses of other counsel
or any other expenses, in each case subsequently incurred by such indemnified
party, in connection with the defense thereof other than reasonable costs of
investigation. No indemnifying party shall, without the written consent of the
indemnified party, effect the settlement or compromise of, or consent to the
entry of any judgment with respect to, any pending or threatened action or claim
in respect of which indemnification or contribution may be sought hereunder
(whether or not the indemnified party is an actual or potential party to such
action or claim) unless such settlement, compromise or judgment (i) includes an
unconditional release of the indemnified party from all liability arising out of
such action or claim and (ii) does not include a statement as to or an admission
of fault, culpability or a failure to act, by or on behalf of any indemnified
party.

     (e) If the indemnification provided for in this Section 8 is unavailable to
or insufficient to hold harmless an indemnified party under subsection (a), (b)
or (c) above in respect of any losses, claims, damages or liabilities (or
actions in respect thereof) referred to therein, then each indemnifying party
shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages or liabilities (or actions in respect
thereof) in such proportion as is appropriate to reflect the relative benefits
received by the Company and the Selling Shareholders on the one hand and the
Underwriters on the other from the offering of the Shares. If, however, the
allocation provided by the immediately preceding sentence is not permitted by
applicable law or if the indemnified party failed to give the notice required
under subsection (d) above, then each indemnifying party shall contribute to
such amount paid or payable by such indemnified party in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of the Company and the Selling Shareholders on the one hand and the
Underwriters on the other in connection with the statements or omissions which
resulted in such losses, claims, damages or liabilities (or actions in respect
thereof), as well as any other relevant equitable considerations (including any
material prejudice as a result of any failure to give notice as required by
subsection (d) above). The relative benefits received by the Company and the
Selling Shareholders on the one hand and the Underwriters on the other shall be
deemed to be in the same proportion as the total net proceeds from the offering
of the Shares purchased under this Agreement (before deducting expenses)
received by the Company and the Selling Shareholders in the underwritten public
offering bear to the total underwriting discounts and commissions received by
the Underwriters with respect to the Shares purchased under this Agreement, in
each case as set forth in the table on the cover page of the Prospectus. The
relative fault shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by the
Company or the Selling Shareholders on the one hand or the Underwriters on the
other and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Company, each
of the Selling Shareholders and the Underwriters agree that it would not be just
and equitable if contributions pursuant to this subsection (e) were determined
by pro rata allocation (even if the Underwriters were treated as one entity for
such purpose) or by any other method of allocation which does not take account
of the equitable considerations referred to above in this subsection (e). The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to above
in this subsection (e) shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in



                                       22

<PAGE>   23

connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this subsection (e), no Underwriter shall be
required to contribute any amount in excess of the amount by which the total
price at which the Shares underwritten by it and distributed to the public were
offered to the public exceeds the amount of any damages which such Underwriter
has otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission and no Selling Shareholder shall be
required to contribute any amount in excess of the product of the number of
Shares sold by such Selling Shareholder and the public offering price of the
Shares as set forth in the Prospectus. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. The Underwriters' obligations in this subsection (e) to
contribute are several in proportion to their respective underwriting
obligations and not joint.

     (f) The obligations of the Company and the Selling Shareholders under this
Section 8 shall be in addition to any liability which the Company and the
respective Selling Shareholders may otherwise have and shall extend, upon the
same terms and conditions, to each person, if any, who controls any Underwriter
within the meaning of the Act; and the obligations of the Underwriters under
this Section 8 shall be in addition to any liability which the respective
Underwriters may otherwise have and shall extend, upon the same terms and
conditions, to each officer and director of the Company and to each person, if
any, who controls the Company or any Selling Shareholder within the meaning of
the Act.

     9. (a) If any Underwriter shall default in its obligation to purchase the
Shares which it has agreed to purchase hereunder at a Time of Delivery, you may
in your discretion arrange for you or another party or other parties to purchase
such Shares on the terms contained herein. If within thirty-six hours after such
default by any Underwriter you do not arrange for the purchase of such Shares,
then the Selling Shareholders shall be entitled to a further period of
thirty-six hours within which to procure another party or other parties
satisfactory to you to purchase such Shares on such terms. In the event that,
within the respective prescribed periods, you notify the Selling Shareholders
that you have so arranged for the purchase of such Shares, or the Selling
Shareholders notify you that they have so arranged for the purchase of such
Shares, you or the Selling Shareholders shall have the right to postpone such
Time of Delivery for a period of not more than seven days, in order to effect
whatever changes may thereby be made necessary in the Registration Statement or
the Prospectus, or in any other documents or arrangements, and the Company
agrees to file promptly any amendments to the Registration Statement or the
Prospectus which in your opinion may thereby be made necessary. The term
"Underwriter" as used in this Agreement shall include any person substituted
under this Section with like effect as if such person had originally been a
party to this Agreement with respect to such Shares.

     (b) If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Selling
Shareholders as provided in subsection (a) above, the aggregate number of such
Shares which remains unpurchased does not exceed one-eleventh of the aggregate
number of all the Shares to be purchased at such Time of Delivery, then the
Selling Shareholders shall have the right to require each non-defaulting
Underwriter to purchase the number of Shares which such Underwriter agreed to
purchase hereunder at such Time of Delivery and, in addition, to require each
non-defaulting Underwriter to purchase its pro rata share (based on the number
of Shares which such Underwriter agreed to purchase hereunder) of the Shares of
such defaulting Underwriter or 



                                       23

<PAGE>   24

Underwriters for which such arrangements have not been made; but nothing herein
shall relieve a defaulting Underwriter from liability for its default.

     (c) If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Selling
Shareholders as provided in subsection (a) above, the aggregate number of such
Shares which remains unpurchased exceeds one-eleventh of the aggregate number of
all the Shares to be purchased at such Time of Delivery, or if the Selling
Shareholders shall not exercise the right described in subsection (b) above to
require non-defaulting Underwriters to purchase Shares of a defaulting
Underwriter or Underwriters, then this Agreement (or, with respect to the Second
Time of Delivery, the obligations of the Underwriters to purchase and of the
Selling Shareholders to sell the Optional Shares) shall thereupon terminate,
without liability on the part of any non-defaulting Underwriter or the Company
or the Selling Shareholders, except for the expenses to be borne by the Company
and the Selling Shareholders and the Underwriters as provided in Section 6
hereof and the indemnity and contribution agreements in Section 8 hereof; but
nothing herein shall relieve a defaulting Underwriter from liability for its
default.

     10. The respective indemnities, agreements, representations, warranties and
other statements of the Company, the Selling Shareholders and the several
Underwriters, as set forth in this Agreement or made by or on behalf of them,
respectively, pursuant to this Agreement, shall remain in full force and effect,
regardless of any investigation (or any statement as to the results thereof)
made by or on behalf of any Underwriter or any controlling person of any
Underwriter, or the Company, or any of the Selling Shareholders, or any officer
or director or controlling person of the Company, or any controlling person of
any Selling Shareholder, and shall survive delivery of and payment for the
Shares.

     Anything herein to the contrary notwithstanding, the indemnity agreement of
the Company in subsection (a) of Section 8 hereof, the representations and
warranties in subsections (a)(ii), (a)(iii) or (a)(iv) of Section 1 hereof and
any representation or warranty as to the accuracy of the Registration Statement
or the Prospectus contained in any certificate furnished by the Company pursuant
to Section 7 hereof, insofar as they may constitute a basis for indemnification
for liabilities (other than payment by the Company of expenses incurred or paid
in the successful defense of any action, suit or proceeding) arising under the
Act, shall not extend to the extent of any interest therein of a controlling
person or partner of an Underwriter who is a director, officer or controlling
person of the Company when the Registration Statement has become effective or
who, with his or her consent, is named in the Registration Statement as about to
become a director of the Company, except in each case to the extent that an
interest of such character shall have been determined by a court of appropriate
jurisdiction as not against public policy as expressed in the Act. Unless in the
opinion of counsel for the Company the matter has been settled by controlling
precedent, the Company will, if a claim for such indemnification is asserted,
submit to a court of appropriate jurisdiction the question of whether the
extension of the indemnification by the Company to such interest is against
public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

     11. If this Agreement shall be terminated pursuant to Section 9 hereof,
neither the Company nor the Selling Shareholders shall then be under any
liability to any Underwriter except as provided in Sections 6 and 8 hereof; but,
if for any other reason any Shares are not delivered by or on behalf of the
Selling Shareholders as provided herein, the Company will reimburse the
Underwriters through you for all out-of-pocket expenses approved in writing by



                                       24

<PAGE>   25

you, including fees and disbursements of counsel, reasonably incurred by the
Underwriters in making preparations for the purchase, sale and delivery of the
Shares not so delivered, but the Company and the Selling Shareholders shall then
be under no further liability to any Underwriter in respect of the Shares not so
delivered except as provided in Sections 6 and 8 hereof.

     12. In all dealings hereunder, you shall act on behalf of each of the
Underwriters, and the parties hereto shall be entitled to act and rely upon any
statement, request, notice or agreement on behalf of any Underwriter made or
given by you jointly or by Goldman, Sachs & Co. on behalf of you as the
representatives; and in all dealings with any Selling Shareholder hereunder, you
and the Company shall be entitled to act and rely upon any statement, request,
notice or agreement on behalf of such Selling Shareholder made or given by any
or all of the Attorneys-in-Fact for such Selling Shareholder.

     All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Underwriters shall be delivered or sent by mail, telex or
facsimile transmission to you as the representatives in care of Goldman, Sachs &
Co., 85 Broad Street, New York, New York 10004, Attention: Registration
Department; if to any Selling Shareholder shall be delivered or sent by mail,
telex or facsimile transmission to counsel for such Selling Shareholder at its
address set forth in Schedule II hereto; and if to the Company shall be
delivered or sent by mail, telex or facsimile transmission to the address of the
Company set forth in the Registration Statement, Attention: Secretary; provided,
however, that any notice to an Underwriter pursuant to Section 8(d) hereof shall
be delivered or sent by mail, telex or facsimile transmission to such
Underwriter at its address set forth in its Underwriters' Questionnaire, or
telex constituting such Questionnaire, which address will be supplied to the
Company or the Selling Shareholders by you upon request. Any such statements,
requests, notices or agreements shall take effect upon receipt thereof.

     13. This Agreement shall be binding upon, and inure solely to the benefit
of, the Underwriters, the Company and the Selling Shareholders and, to the
extent provided in Sections 8 and 10 hereof, the officers and directors of the
Company and each person who controls the Company, any Selling Shareholder or any
Underwriter, and their respective heirs, executors, administrators, successors
and assigns, and no other person shall acquire or have any right under or by
virtue of this Agreement. No purchaser of any of the Shares from any Underwriter
shall be deemed a successor or assign by reason merely of such purchase.

     14. Time shall be of the essence of this Agreement. As used herein, the
term "business day" shall mean any day when the Commission's office in
Washington, D.C. is open for business.

     15. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF NEW YORK.

     16. This Agreement may be executed by any one or more of the parties hereto
in any number of counterparts, each of which shall be deemed to be an original,
but all such counterparts shall together constitute one and the same instrument.

     Pursuant to Section 7(g) of the Underwriting Agreement, the accountants
shall furnish letters to the Underwriters to the effect that:

    (i) They are independent certified public accountants with respect to the
Company and its subsidiaries within the meaning of the Act and the applicable
published rules and regulations thereunder;

   (ii) In their opinion, the financial statements and any supplementary
financial information and schedules (and, if applicable, financial forecasts
and/or pro forma financial information) examined by them and included or
incorporated by reference in the Registration Statement or the Prospectus comply
as to form in all material respects with the applicable accounting requirements
of the Act or the Exchange Act, as applicable, and the related published rules
and regulations thereunder; and, if applicable, they have made a review in
accordance with standards established by the American Institute of Certified
Public Accountants of the consolidated interim financial statements, selected
financial data, pro forma financial information, financial forecasts and/or
condensed financial statements derived from audited financial statements of the
Company for the periods specified in such letter, as indicated in their reports
thereon, copies of which have been separately furnished to the representatives
of the Underwriters (the "Representatives");

  (iii) They have made a review in accordance with standards established by the
American Institute of Certified Public Accountants of the unaudited condensed
consolidated statements of income, consolidated balance sheets and consolidated
statements of cash flows included in the Prospectus and/or included in the
Company's Quarterly Report on Form 10-Q incorporated by reference into the
Prospectus as indicated in their reports thereon copies of which have been
separately furnished to the Representatives; and on the basis of specified
procedures including inquiries of officials of the Company who have
responsibility for financial and accounting matters regarding whether the
unaudited condensed consolidated financial statements referred to in paragraph
(vi)(A)(i) below comply as to form in all material respects with the applicable
accounting requirements of the Act and the Exchange Act and the related
published rules and regulations, nothing came to their attention that caused
them to believe that the unaudited condensed consolidated financial statements
do not comply as to form in all material respects with the applicable accounting
requirements of the Act and the Exchange Act and the related published rules and
regulations;

   (iv) The unaudited selected financial information with respect to the
consolidated results of operations and financial position of the Company for the
five most recent fiscal years included in the Prospectus agrees with the
corresponding amounts (after restatements where applicable) in the audited
consolidated financial statements for such five fiscal years which were included
or incorporated by reference in the Company's Annual Reports on Form 10-K for
such fiscal years;

    (v) They have compared the information in the Prospectus under selected
captions with the disclosure requirements of Regulation S-K and on the basis of
limited procedures specified in such letter nothing came to their attention as a
result of the foregoing procedures that caused them to believe that this
information does not conform in all material respects with the disclosure
requirements of Items 301, 302, 402 and 503(d), respectively, of Regulation S-K;

<PAGE>   31



   (vi) On the basis of limited procedures, not constituting an examination in
accordance with generally accepted auditing standards, consisting of a reading
of the unaudited financial statements and other information referred to below, a
reading of the latest available interim financial statements of the Company and
its subsidiaries, inspection of the minute books of the Company and its
subsidiaries since the date of the latest audited financial statements included
in the Prospectus, inquiries of officials of the Company and its subsidiaries
responsible for financial and accounting matters and such other inquiries and
procedures as may be specified in such letter, nothing came to their attention
that caused them to believe that:

         (A) (i) the unaudited condensed consolidated statements of income,
     consolidated balance sheets and consolidated statements of cash flows
     included in the Prospectus and/or included or incorporated by reference in
     the Company's Quarterly Reports on Form 10-Q incorporated by reference in
     the Prospectus do not comply as to form in all material respects with the
     applicable accounting requirements of the Exchange Act and the related
     published rules and regulations, or (ii) any material modifications should
     be made to the unaudited condensed consolidated statements of income,
     consolidated balance sheets and consolidated statements of cash flows
     included in the Prospectus or included in the Company's Quarterly Reports
     on Form 10-Q incorporated by reference in the Prospectus, for them to be in
     conformity with generally accepted accounting principles;

         (B) any other unaudited income statement data and balance sheet items
     included in the Prospectus do not agree with the corresponding items in the
     unaudited consolidated financial statements from which such data and items
     were derived, and any such unaudited data and items were not determined on
     a basis substantially consistent with the basis for the corresponding
     amounts in the audited consolidated financial statements included or
     incorporated by reference in the Company's Annual Report on Form 10-K for
     the most recent fiscal year;

         (C) the unaudited financial statements which were not included in the
     Prospectus but from which were derived the unaudited condensed financial
     statements referred to in Clause (A) and any unaudited income statement
     data and balance sheet items included in the Prospectus and referred to in
     Clause (B) were not determined on a basis substantially consistent with the
     basis for the audited consolidated financial statements included or
     incorporated by reference in the Company's Annual Report on Form 10-K for
     the most recent fiscal year;

         (D) any unaudited pro forma consolidated condensed financial statements
     included or incorporated by reference in the Prospectus do not comply as to
     form in all material respects with the applicable accounting requirements
     of the Act and the published rules and regulations thereunder or the pro
     forma adjustments have not been properly applied to the historical amounts
     in the compilation of those statements;

         (E) as of a specified date not more than five days prior to the date of
     such letter, there have been any changes in the consolidated capital stock
     (other than issuances of capital stock upon exercise of options and stock
     appreciation rights, upon earn-outs of performance shares and upon
     conversions of convertible securities, in each case which were outstanding
     on the date of the latest balance sheet included or incorporated by
     reference in the Prospectus) or any increase in the consolidated long-term
     debt of the Company and its subsidiaries, or any decreases in consolidated
     net current assets or shareholders' equity or other items specified by the
     Representatives, or any increases in any items specified by the
     Representatives, in each case as compared with amounts

     shown in the latest balance sheet included or incorporated by reference in
     the Prospectus, except in each case for changes, increases or decreases
     which the Prospectus discloses have occurred or may occur or which are
     described in such letter; and

         (F) for the period from the date of the latest financial statements
     included or incorporated by reference in the Prospectus to the specified
     date referred to in Clause (E) there were any decreases in consolidated net
     revenues or operating profit or the total or per share amounts of
     consolidated net income or other items specified by the Representatives, or
     any increases in any items specified by the Representatives, in each case
     as compared with the comparable period of the preceding year and with any
     other period of corresponding length specified by the Representatives,
     except in each case for increases or decreases which the Prospectus
     discloses have occurred or may occur or which are described in such letter;
     and

  (vii) In addition to the examination referred to in their report(s) included
or incorporated by reference in the Prospectus and the limited procedures,
inspection of minute books, inquiries and other procedures referred to in
paragraphs (iii) and (vi) above, they have carried out certain specified
procedures, not constituting an examination in accordance with generally
accepted auditing standards, with respect to certain amounts, percentages and
financial information specified by the Representatives which are derived from
the general accounting records of the Company and its subsidiaries, which appear
in the Prospectus (excluding documents incorporated by reference) or in Part II
of, or in exhibits and schedules to, the Registration Statement specified by the
Representatives or in documents incorporated by reference in the Prospectus
specified by the Representatives, and have compared certain of such amounts,
percentages and financial information with the accounting records of the Company
and its subsidiaries and have found them to be in agreement.

     Re: Registration Statement on Form S-3
 
Ladies and Gentleman:
 
     In connection with the registration of shares of Class A Common Stock, no
par value per share (the "Shares"), of Western Wireless Corporation (the
"Company") with the Securities and Exchange Commission on a Registration
Statement on Form S-3 (the "Registration Statement"), relating to the sales of
the Shares by certain selling shareholders named in the Registration Statement,
we have examined such documents, records and matters of law as we have
considered relevant.
 
     Based on this review, it is our opinion that the Shares will be fully paid
and non-assessable under the Washington Business Corporation Act when
certificates representing the Shares shall have been duly executed,
countersigned and registered and duly delivered to the purchasers thereof
against payment of the agreed consideration therefor.
 
     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to all references to our firm included in or made a
part of the Registration Statement.
 
                                          Very truly yours,
 
                                          PRESTON GATES & ELLIS LLP
 
                                          By:    /s/ G. SCOTT GREENBURG

                   CONSENT OF INDEPENDENT PUBLIC ACCOUNTANTS

report included in this registration statement and to the incorporation by
reference in this registration statement of our report dated February 17, 1998
