ITEM 1. BUSINESS

Telephone and Data Systems, Inc. (the "Company" or "TDS"), is a diversified
telecommunications service company with cellular telephone, telephone and
personal communications services ("PCS") operations. At December 31, 1998, the
Company served approximately 3.0 million customer units in 35 states, including
2,183,000 cellular telephones, 547,500 telephone access lines and 311,900 PCS
telephones. For the year ended December 31, 1998, cellular operations provided
64% of the Company's consolidated revenues; telephone operations provided 27%;
and PCS operations provided 9%. The Company's long-term business development
strategy is to expand its existing operations through internal growth and
acquisitions and to explore and develop other telecommunications businesses that
management believes will utilize the Company's expertise in customer-based
telecommunications.

The Company conducts substantially all of its cellular operations through
its 81.0%-owned subsidiary, United States Cellular Corporation [AMEX: USM]. At
December 31, 1998, U.S. Cellular provided cellular telephone service to
2,183,000 customers through 138 majority-owned and managed ("consolidated")
cellular systems serving approximately 17% of the geography and approximately 9%
of the population of the United States. Since 1985, when U.S. Cellular began
providing cellular service in Knoxville, Tennessee, U.S. Cellular has expanded
its cellular networks and customer service operations to cover 145 managed
markets in 26 states as of December 31, 1998. In total, the Company operated
eight market clusters, of which four had a total population of more than two
million, and each of which had a total population of more than one million.
Overall, 90% of the Company's 26.2 million population equivalents were in
markets which were consolidated, 2% were in managed but not consolidated markets
and 8% were in markets in which the Company holds an investment interest.

The Company conducts substantially all of its telephone operations through
its wholly-owned subsidiary, TDS Telecommunications Corporation ("TDS Telecom").
At December 31, 1998, TDS Telecom operated 105 telephone companies serving
547,500 access lines in 28 states. TDS Telecom is expanding by offering
additional lines of telecommunications products and services to existing
customers and through the selective acquisition of local exchange telephone
companies serving rural and suburban areas. TDS Telecom has acquired 16
telephone companies and divested one telephone company since the beginning of
1994. These net acquisitions added 76,000 access lines during this five-year
period, while internal growth added 115,300 lines. TDS Telecom also began
offering services as a Competitive Local Exchange Carrier ("CLEC") in 1998 in
certain markets in Wisconsin and Minnesota. At December 31, 1998, TDS Telecom's
CLECs served 38,800 access lines.

The Company conducts substantially all of its broadband PCS operations
through its 82.3%-owned subsidiary, Aerial Communications, Inc. [NASDAQ: AERL].
Aerial provides PCS service in the Minneapolis, Tampa-St. Petersburg-Orlando,
Houston, Pittsburgh, Kansas City and Columbus Major

3
Trading Areas ("MTAs") (collectively, the "PCS Markets"). The PCS Markets
include approximately 27.7 million population equivalents. Aerial has commenced
service in all its markets and provided service to 311,900 PCS telephones as of
December 31, 1998.

The Company was incorporated in 1968 and changed its corporate domicile from
Iowa to Delaware in 1998. The Company's executive offices are located at 30
North LaSalle Street, Chicago, Illinois 60602. Its telephone number is
312-630-1900.

or a PCS system in such market.

PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995 SAFE HARBOR CAUTIONARY
STATEMENT

This Annual Report on Form 10-K, including exhibits, contains
"forward-looking" statements, as defined in the Private Securities Litigation
Reform Act of 1995, that are based on current expectations, estimates and
projections. Statements that are not historical facts, including statements
about the Company's beliefs and expectations are forward-looking statements.
These statements contain potential risks and uncertainties and, therefore,
actual results may differ materially. TDS undertakes no obligation to update
publicly any forward-looking statements whether as a result of new information,
future events or otherwise.

Important factors that may affect these projections or expectations include,
but are not limited to: changes in the overall economy; changes in competition
in markets in which TDS operates; advances in telecommunications technology;
changes in the telecommunications regulatory environment; pending and future
litigation; availability of future financing; unanticipated changes in growth in
cellular and PCS customers, penetration rates, churn rates; the mix of products
and services offered in the Company's markets; and unanticipated problems with
the Year 2000 Issue. Readers should evaluate any statements in light of these
important factors.

PROPOSED CORPORATE RESTRUCTURING

In December 1997, the Board of Directors of Telephone and Data Systems, Inc.
adopted a proposal, which was approved by the shareholders in April 1998, to
authorize three new classes of common stock and to change the state of
incorporation of TDS from Iowa to Delaware. The three new classes of stock were
intended to separately reflect the performance of the Company's cellular
telephone, telephone and personal communications services businesses ("Tracking
Stocks"). The reincorporation was completed May 1998.

The Company intended to: a) offer and sell Telecom Group Shares in a public
offering for cash, b) issue Cellular Group Shares in exchange for all of the
Common Shares of U.S. Cellular not owned by the Company, c) issue Aerial Group
Shares in exchange for all of the Common Shares of Aerial not owned by the
Company, and d) distribute one Cellular Group Share, two-thirds of a Telecom
Group Share and two-thirds of an Aerial Group Share in the form of a stock
dividend with respect to each outstanding Series A Common Share and Common Share
of the Company.

4
In December 1998, TDS announced the withdrawal of its offers to exchange
tracking stocks for the outstanding Common Shares of U.S. Cellular and Aerial
which it did not own. An integral part of the tracking stock plan was the
offering of shares in the Telecom Group, which TDS was not able to complete at a
reasonable offering price. In addition, TDS was unable to reach mutually
acceptable agreements with the special committees representing the minority
shareholders of U.S. Cellular and Aerial.

At the same time TDS announced that it was pursuing a tax-free spin-off of
its 82.3% interest in Aerial, as well as reviewing other alternatives. There are
a number of conditions that must be met for a spin-off to occur, including the
receipt of a favorable Internal Revenue Service ruling on the tax free status of
such a spin-off, final approval by the TDS Board of Directors, certain
government and third party approvals and review by the Securities and Exchange
Commission ("SEC") of appropriate SEC filings.

Prior to any spin-off, it is expected that Aerial will seek additional
financing so that Aerial would have the appropriate capitalization to operate as
a stand-alone entity. In connection with such financing, it is anticipated that
a substantial amount of Aerial's debt to TDS may be converted into equity. TDS
intends to seek shareholder approval of a proposal to distribute Aerial Series A
Common Shares, on a pro-rata basis, to holders of TDS Series A Common Shares and
Aerial Common Shares, on a pro-rata basis, to holders of TDS Common Shares.
There can be no assurance that a spin-off will be consummated or that other
alternatives will not be pursued.

In September 1998, pursuant to a purchase agreement between TDS, Aerial,
Aerial Operating Company, Inc. ("AOC"), and Sonera Ltd., a limited liability
company organized under the laws of Finland ("Sonera"), Sonera purchased 2.4
million shares of common stock of AOC representing a 19.423% equity interest in
AOC, subject to adjustment under certain circumstances, for an aggregate
purchase price of $200 million. Sonera has the right, subject to adjustment
under certain circumstances, to exchange each share of AOC, common stock which
it owns for 6.72919 Common Shares of Aerial. Upon the exchange of all of the AOC
shares, Sonera would own an 18.452% equity interest in Aerial, reflecting a
purchase price equivalent to $12.33 per Common Share of Aerial (the "Equivalent
Purchase Price").

Following the announcement by TDS in December 1998, that it intended to
distribute to its shareholders all of the capital stock of Aerial that it owns,
and that Aerial would seek additional financing from sources other than TDS in
connection therewith, Sonera contacted TDS to express certain concerns about the
announcement. Sonera has asserted that the TDS announcement reflects a change in
circumstances that warrant the renegotiation of certain matters related to its
investment in AOC, including an adjustment in the Equivalent Purchase Price, and
has raised the possibility of litigation in connection therewith. TDS and Aerial
intend to attempt to reach a mutually acceptable resolution of the concerns
raised by Sonera. There can be no assurance that this matter will not lead to
litigation, or that it will not have a material adverse effect on TDS or Aerial
or on the plans relating to the refinancing and spin-off of Aerial.

CELLULAR TELEPHONE OPERATIONS

The Company's cellular operations are conducted through U.S. Cellular and
its subsidiaries. U.S. Cellular is the eleventh largest wireless company in the
United States, based on the aggregate number of customers in its consolidated
markets. U.S. Cellular's corporate development strategy is to operate
controlling interests in cellular market licensees in areas adjacent to or in
proximity to its other markets, thereby building clusters of operating markets.
Customers benefit from larger service areas such as these, which provide longer
uninterrupted service and the ability to make outgoing calls and receive
incoming calls within the designated area without special roaming arrangements.
In addition, U.S. Cellular anticipates that clustering will continue to provide
it certain economies in its capital and operating costs. As the number of
opportunities for outright acquisitions has decreased in recent years, and as
U.S. Cellular's clusters have grown, U.S. Cellular's focus has shifted toward
exchanges and divestitures of managed and investment interests which are
considered less essential to U.S. Cellular's clustering strategy.

The following table summarizes the status of U.S. Cellular's interests in
cellular markets at December 31, 1998.

(1) Represents markets in which U.S. Cellular owns a minority or other
noncontrolling interest and which are managed by third parties; as of
December 31, 1998, U.S. Cellular accounted for its interests in 31 of these
markets using the equity method and accounted for the remaining seven
markets using the cost method.

Cellular systems in U.S. Cellular's 138 majority-owned and managed markets
served 2,183,000 customers at December 31, 1998, and contained 2,065 cell sites.
The average penetration rate in U.S. Cellular's consolidated markets was 8.84%
at December 31, 1998, and the churn rate in all consolidated markets averaged
1.9% per month for the twelve months ended December 31, 1998.

THE CELLULAR TELEPHONE INDUSTRY

Cellular telephone technology provides high-quality, high-capacity
communications services to in-vehicle and hand-held portable cellular
telephones. Cellular technology is a major improvement over earlier mobile
telephone technologies. Cellular telephone systems are designed for maximum
mobility of the customer. Access is provided through system interconnections to
local, regional, national and world-wide telecommunications networks. Cellular
telephone systems also offer a full range of ancillary services such as
conference calling, call-waiting, call-forwarding, voice mail, facsimile and
data transmission.

Cellular telephone systems divide each service area into smaller geographic
areas or "cells." Each cell is served by radio transmitters and receivers
operating on discrete radio frequencies licensed by the FCC. All of the cells in
a system are connected to a computer-controlled Mobile Telephone Switching
Office ("MTSO"). The MTSO is connected to the conventional ("landline")
telephone network and potentially other MTSOs. Each conversation on a cellular
phone involves a transmission over a specific set of radio frequencies from the
cellular phone to a transmitter/receiver at a cell site. The transmission is
forwarded from the cell site to the MTSO and from there may be forwarded to the
landline telephone network to complete the call. As the cellular telephone moves
from one cell to another, the MTSO determines radio signal strength and
transfers ("hands off") the call from one cell to the next. This hand-off is not
noticeable to either party on the phone call.

The FCC currently grants only two licenses to provide cellular telephone
service in each market. However, competition for customers includes competing
communications technologies such as conventional landline and mobile telephone,
Specialized Mobile Radio ("SMR") systems, radio paging and PCS. PCS has become
available in many areas of the United States, including U.S. Cellular's markets,
and U.S. Cellular expects PCS operators to continue deployment of PCS in
portions of all of U.S. Cellular's clusters through 1999. Additionally,
technologies such as Enhanced Specialized Mobile Radio ("ESMR") and mobile
satellite communication systems may prove to be competitive with cellular
service in the future in some or all of U.S. Cellular's markets.

The services available to cellular customers and the sources of revenue
available to cellular system operators are similar to those provided by
conventional landline telephone companies. Customers may be charged a separate
fee for system access, airtime, long-distance calls and ancillary services.
Cellular system operators often provide service to customers of other operators'
cellular systems while the customers are temporarily located within the
operators' service areas. Customers using service away from their home system
are called "roamers." Roaming is not limited to cellular customers and systems;

6
PCS customers and systems have this roaming capability as well. In all cases,
the system that provides the service to roamers will generate usage revenue.
Many operators, including U.S. Cellular, charge premium rates for this roaming
service.

There have been a number of technical developments in the cellular industry
since its inception. Currently, while most companies' MTSOs process information
digitally, on certain cellular systems the radio transmission is done on an
analog basis. During 1992, a new transmission technique was approved for
implementation by the cellular industry. Time Division Multiple Access ("TDMA")
technology was selected as one industry standard by the cellular industry and
has been deployed in several markets, including U.S. Cellular's operations in
portions of several clusters. Another digital technology, Code Division Multiple
Access ("CDMA"), is also being deployed by U.S. Cellular in portions of several
clusters. Digital radio technology offers several advantages, including greater
privacy, less transmission noise, greater system capacity and potentially lower
incremental costs to accommodate additional system usage. The conversion from
analog to digital radio technology is continuing on an industry-wide basis;
however, this process is expected to take a number of years. PCS operators have
deployed TDMA, CDMA and a third digital technology, Global System for Mobile
Communication ("GSM"), in the markets where they have begun operations.

The cellular telephone industry is characterized by high initial fixed
costs. Accordingly, if and when revenues less variable costs exceed fixed costs,
incremental revenues should yield an operating profit. The amount of profit, if
any, under such circumstances is dependent on, among other things, prices and
variable marketing costs which in turn are affected by the amount and extent of
competition. Until technological limitations on total capacity are approached,
additional cellular system capacity can normally be added in increments that
closely match demand and at less than the proportionate cost of the initial
capacity.

CELLULAR OPERATIONS

From its inception in 1983 until 1993, U.S. Cellular was principally in a
start-up phase. Until 1993, U.S. Cellular's activities had been concentrated
significantly on the acquisition of interests in cellular licensees and on the
construction and initial operation of cellular systems. The development of a
cellular system is capital-intensive and requires substantial investment prior
to and subsequent to initial operation. U.S. Cellular experienced operating
losses and net losses from its inception until 1993. During the past five years,
U.S. Cellular generated operations-driven net income and has significantly
increased its operating cash flows during that time. Management anticipates
further growth in cellular units in service and revenues as U.S. Cellular
continues to expand through internal growth. Marketing and system operations
expenses associated with this expansion may reduce the rate of growth in
operating cash flows and operating income during the period of additional
growth. In addition, U.S. Cellular anticipates that the seasonality of revenue
streams and operating expenses may cause U.S. Cellular's operating income to
vary from quarter to quarter.

While U.S. Cellular produced operating income and net income during the last
five years, changes in any of several factors may reduce U.S. Cellular's growth
in operating income and net income over the next few years. These factors
include: (i) the growth rate in U.S. Cellular's customer base; (ii) the usage
and pricing of cellular services; (iii) the churn rate; (iv) the cost of
providing cellular services, including the cost of attracting new customers; (v)
continued competition from PCS and other technologies; and (vi) continuing
technological advances which may provide additional competitive alternatives to
cellular service.

U.S. Cellular is building a substantial presence in selected geographic
areas throughout the United States where it can efficiently integrate and manage
cellular telephone systems. Its cellular interests include regional market
clusters in the following areas: Wisconsin/Illinois,
Iowa/Missouri/Illinois/Indiana, Eastern North Carolina/South Carolina, West
Virginia/Maryland/Pennsylvania/Ohio, Virginia/North Carolina,
Washington/Oregon/Idaho, Oregon/California, Maine/New Hampshire/Vermont,
Florida/Georgia,

7
Oklahoma/Missouri/Kansas, Texas/Oklahoma, Eastern Tennessee/Western North
Carolina and Southern Texas. See "U.S. Cellular's Cellular Interests." U.S.
Cellular has acquired its cellular interests through the wireline application
process (16%), including settlements and exchanges with other applicants, and
through acquisitions (84%), including acquisitions from TDS and third parties.

CELLULAR SYSTEMS DEVELOPMENT

ACQUISITIONS, DIVESTITURES AND EXCHANGES. U.S. Cellular assesses its
cellular holdings on an ongoing basis in order to maximize the benefits derived
from clustering its markets. As U.S. Cellular's clusters have grown, its focus
has shifted toward exchanges and divestitures of managed and investment
interests, with outright acquisitions becoming a decreasing portion of U.S.
Cellular's overall acquisition strategy. As a result, U.S. Cellular has not
substantially increased its population equivalents during the past five years,
but has shifted the balance of its holdings between investment and operating
interests so that currently over 90% of U.S. Cellular's interests are in markets
where it is the operator. This shift has resulted primarily because of U.S.
Cellular's recent focus on exchanges and divestitures of investment interests
and the acquisitions of interests in markets where it will become the operator.

U.S. Cellular has only increased its population equivalents by 5% in the
last five years, from approximately 24.8 million at December 31, 1993, to
approximately 26.1 million at December 31, 1998. However, during that period
U.S. Cellular has increased the percentage of those population equivalents which
are in markets U.S. Cellular operates. As of December 31, 1998, 92% of U.S.
Cellular's population equivalents represented interests in markets U.S. Cellular
operates compared to 81% at December 31, 1993. Also, the number of markets
operated by U.S. Cellular have increased to 145 markets at December 31, 1998
from 136 markets at December 31, 1993.

Recently, the pace of acquisitions, exchanges and divestitures has slowed as
industry-wide consolidation has reduced the number of markets available for
acquisition. U.S. Cellular may continue to make opportunistic acquisitions or
exchanges in markets that further strengthen its market clusters and in other
attractive markets. U.S. Cellular also seeks to acquire minority interests in
markets where it already owns the majority interest and/or operates the market.
There can be no assurance that U.S. Cellular, or TDS for the benefit of U.S.
Cellular, will be able to negotiate additional acquisitions or exchanges on
terms acceptable to it or that regulatory approvals, where required, will be
received. U.S. Cellular plans to retain minority interests in certain cellular
markets which it believes will earn a favorable return on investment. Other
minority interests may be exchanged for interests in markets which enhance U.S.
Cellular's market clusters or may be sold for cash or other consideration. U.S.
Cellular also continues to evaluate the disposition of certain managed interests
which are not essential to its corporate development strategy.

COMPLETED ACQUISITIONS. During 1998, U.S. Cellular, or TDS for the benefit
of U.S. Cellular, purchased majority interests in six markets and several
additional minority interests, representing approximately 1.3 million population
equivalents. The total consideration paid for these purchases, primarily in the
form of cash and U.S. Cellular Common Shares issued to TDS to reimburse TDS for
the value of TDS Common Shares issued to third parties, totaled $168.3 million.

COMPLETED DIVESTITURES. During 1998, U.S. Cellular and TDS sold a majority
interest in one market and several minority interests, representing
approximately 1.2 million population equivalents. In exchange, U.S. Cellular and
TDS received approximately 5.2 million AirTouch Communications, Inc.
("AirTouch") common shares and cash totaling $119.7 million.

PENDING ACQUISITIONS AND DIVESTITURE. At December 31, 1998, U.S. Cellular
had agreements pending to acquire minority interests in two markets in which
U.S. Cellular currently owns majority interests, representing 74,000 population
equivalents, for $8.1 million in cash. Also at December 31, 1998 U.S. Cellular
had an agreement pending to divest a majority interest in one market,
representing 264,000 population equivalents, for a total consideration of $35.2
million. U.S. Cellular expects all of the pending transactions to be completed
during the first half of 1999.

TDS and U.S. Cellular maintain shelf registrations of Common Shares and
Preferred Stock under the Securities Act of 1933 for issuance specifically in
connection with acquisitions.

8
U.S. Cellular is a majority-owned subsidiary of TDS. At December 31, 1998,
TDS owned 81.0% of the combined total of the outstanding Common Shares and
Series A Common Shares of U.S. Cellular and controlled 95.7% of the combined
voting power of both classes of common stock.

CELLULAR INTERESTS AND CLUSTERS

U.S. Cellular operates clusters of adjacent cellular systems in nearly all
of its markets, enabling its customers to benefit from larger service areas than
otherwise possible. Where U.S. Cellular offers wide-area coverage, its customers
enjoy uninterrupted service within the designated area. Customers may also make
outgoing calls and receive incoming calls within this area without special
roaming arrangements. In addition to benefits to customers, clustering also has
provided to U.S. Cellular certain economies in its capital and operating costs.
These economies are made possible through increased sharing of facilities,
personnel and other costs and have resulted in a reduction of U.S. Cellular's
per customer cost of service. The extent to which U.S. Cellular benefits from
these revenue enhancements and economies of operation is dependent on market
conditions, population size of each cluster and engineering considerations.

U.S. Cellular may continue to make opportunistic acquisitions and exchanges
which will complement its established market clusters. From time to time, U.S.
Cellular may also consider exchanging or selling its interests in markets which
do not fit well with its long-term strategies.

U.S. Cellular owned interests in cellular telephone systems in 183 markets
at December 31, 1998, representing 26.4 million population equivalents.
Including the minority interests to be purchased and the majority interest to be
sold during 1999, U.S. Cellular owned or had the right to acquire 182 markets,
representing 26.2 million population equivalents, at December 31, 1998. The
following table summarizes the growth in U.S. Cellular's population equivalents
in recent years and the development status of these population equivalents.

long-term goal of allowing delivery of cellular service to areas of economic
interest and along corridors of economic activity. The number of population
equivalents represented by U.S. Cellular's cellular interests may have no direct
relationship to the number of potential cellular customers or the revenues that
may be realized from the operation of the related cellular systems.

SYSTEM DESIGN AND CONSTRUCTION. U.S. Cellular designs and constructs its
systems in a manner it believes will permit it to provide high-quality service
to mobile, transportable and portable cellular telephones, based on market and
engineering studies which relate to specific markets. Engineering studies are
performed by U.S. Cellular personnel or independent engineering firms. U.S.
Cellular's switching equipment is digital, which reduces noise and crosstalk and
is capable of interconnecting in a manner which reduces costs of operation.
While digital microwave interconnections are typically made between the MTSO and
cell sites, both analog and digital radio transmissions are made between cell
sites and the cellular telephones themselves. Network reliability is given
careful consideration and extensive redundancy is employed in virtually all
aspects of U.S. Cellular's network design. Route diversity, ring topology and
extensive use of emergency standby power are also utilized to enhance network
reliability and minimize service disruption from any particular network failure.

10
In accordance with its strategy of building and strengthening market
clusters, U.S. Cellular has selected high capacity digital cellular switching
systems that are capable of serving multiple markets through a single MTSO. U.S.
Cellular's cellular systems are designed to facilitate the installation of
equipment which will permit microwave interconnection between the MTSO and the
cell site. U.S. Cellular has implemented such microwave interconnection in most
of the cellular systems it manages. In other systems in which U.S. Cellular owns
a majority interest and where it is believed to be cost-efficient, such
microwave technology will also be implemented. Otherwise, such systems will rely
upon landline telephone connections to link cell sites with the MTSO. Although
the installation of microwave network interconnection equipment requires a
greater initial capital investment, a microwave network enables a system
operator to avoid the current and future charges associated with leasing
telephone lines from the landline telephone company, while generally improving
system reliability. In addition, microwave facilities can be used to connect
separate cellular systems to allow shared switching, which reduces the aggregate
cost of the equipment necessary to operate multiple systems. Microwave
facilities can also be used to carry long-distance calls, which reduces the
costs of interconnecting to the landline network.

U.S. Cellular has continued to expand its Wide Area Network to accommodate
various business functions, including: automatic call delivery, intersystem
handoff, credit validation, fraud prevention, network management, long-distance
traffic, SS7 signaling and virtually all internal data communications between
various U.S. Cellular office locations and a significant number of U.S.
Cellular's retail locations.

Management believes that currently available technologies will allow
sufficient capacity on U.S. Cellular's networks to meet anticipated demand over
the next few years.

COSTS OF SYSTEM CONSTRUCTION AND FINANCING

Construction of cellular systems is capital-intensive, requiring substantial
investment for land and improvements, buildings, towers, MTSOs, cell site
equipment, microwave equipment, engineering and installation. U.S. Cellular,
consistent with FCC control requirements, uses primarily its own personnel to
engineer and oversee construction of each cellular system it owns and operates.
In so doing, U.S. Cellular expects to improve the overall quality of its systems
and to reduce the expense and time required to make them operational.

The costs (exclusive of license costs) of the systems in which U.S. Cellular
owns an interest have historically been financed through capital contributions
or intercompany loans from U.S. Cellular to the entities owning the systems, and
through certain vendor financing. In recent years, these funding requirements
have been met with cash generated from operations, proceeds from debt and equity
offerings and proceeds from the sales of cellular interests.

MARKETING

U.S. Cellular's marketing plan is centered around rapid penetration of its
market clusters, increasing customer awareness of cellular service and reducing
churn through both the building of brand awareness and the implementation of
marketing programs. The marketing plan stresses the value of U.S. Cellular's
service offerings and incorporates combinations of rate plans and cellular
telephone equipment which are designed to meet the needs of a variety of
customer segments and their usage patterns. U.S. Cellular's distribution
channels include direct sales personnel, agents and retail service centers in
the vast majority of its markets.

U.S. Cellular-owned and managed locations are designed to market cellular
service to the consumer segment in a familiar setting. In late 1997, U.S.
Cellular expanded its e-commerce site to offer three rate plans across the
country aimed at each of U.S. Cellular's three major segments. Sales are
relatively light at this time, but U.S. Cellular anticipates that as customers
become more comfortable with on-line purchasing the Internet will become more of
a robust marketing channel.

U.S. Cellular manages each cluster of markets with a local staff, including
sales, customer service, engineering and in some cases installation personnel.
Direct sales consultants market cellular service to business customers
throughout each cluster. Retail associates work out of the retail locations and
market cellular service primarily to the consumer and small business segment.
U.S. Cellular maintains

11
an ongoing training program to improve the effectiveness of sales consultants
and retail associates by focusing their efforts on obtaining customers and
maximizing the sale of high-user packages. These packages provide for customers
to obtain a minimum amount of usage at discounted rates per minute, at fixed
prices which are charged even if usage falls below a defined monthly minimum
amount.

U.S. Cellular continues to expand its relationships with agents, dealers and
non-U.S. Cellular retailers to obtain customers. Agents and dealers are
independent business people who obtain customers for U.S. Cellular on a
commission basis. U.S. Cellular's agents are generally in the business of
selling cellular telephones, cellular service packages and other related
products. U.S. Cellular's dealers include car stereo companies and other
companies whose customers are also potential cellular customers. The non-U.S.
Cellular retailers include car dealers, major appliance dealers, office supply
dealers and mass merchants.

U.S. Cellular opened its first retail locations in late 1993, expanding to
over 280 stand-alone retail stores by the end of 1998. These U.S. Cellular-owned
and operated businesses utilize rental facilities in high-traffic areas,
primarily in strip malls. U.S. Cellular has implemented a uniform appearance in
these stores, with all having similar displays and layouts. The retail centers'
hours of business match those of the retail trade in the local marketplace,
often staying open on weekends and later in the evening than a typical business
supplier. To fully serve customer needs, these stores sell accessories to
complement the phones and services U.S. Cellular has traditionally provided.
During 1998, U.S. Cellular further expanded its retail presence by opening
smaller retail kiosks within other larger merchandisers, called "stores within a
store," and had several of these locations in place at year-end. Additionally,
U.S. Cellular operates small kiosks within stores such as Wal-Mart and staffs
those kiosks with U.S. Cellular personnel. At December 31, 1998, U.S. Cellular
managed nearly 170 of these kiosks.

U.S. Cellular actively pursues national retail accounts, as agents of U.S.
Cellular, which yield new customer additions in multiple markets. Agreements
have been entered into with such national distributors as Ford Motor Company,
General Motors, Radio Shack, Best Buy, Circuit City, Staples, Office Depot,
Sears, TDS Telecom, TSR Wireless and Onstar in certain of U.S. Cellular's
markets. Upon the sale of a cellular telephone by one of these national
distributors, U.S. Cellular receives, often exclusively within the territories
served, the resulting cellular customer. U.S. Cellular created a new class of
agent during 1998, the Value Added Distributor agent channel. This channel's
initial focus was on the sale of U.S. Cellular's prepaid service product,
TalkTracker, to selected market segments, and complements U.S. Cellular's own
distribution channels.

U.S. Cellular uses a variety of direct mail, billboard, radio, television
and newspaper advertising to stimulate interest by prospective customers in
purchasing U.S. Cellular's cellular service and to establish familiarity with
U.S. Cellular's name. In 1998, U.S. Cellular increased its focus on brand
advertising, including the addition of several new television commercials, using
the tag line "The Way People Talk Around Here"-SM- to promote the United States
Cellular-Registered Trademark- brand. Additionally, U.S. Cellular began actively
advertising its digital service offerings through both television and radio
advertising during the year. Advertising is directed at gaining customers,
improving customers' awareness of the United States
Cellular-Registered Trademark- brand, increasing existing customers' usage and
increasing the public awareness and understanding of the cellular services
offered by U.S. Cellular. U.S. Cellular attempts to select the advertising and
promotion media that are most appealing to the targeted groups of potential
customers in each local market. U.S. Cellular utilizes local advertising media
and public relations activities and establishes programs such as its
CommunityCare programs to enhance public awareness of U.S. Cellular. These
programs are aimed at supporting the communities in which U.S. Cellular serves.
The programs range from loaning phones to support public service operations in
emergencies to assisting victims of domestic abuse.

CUSTOMERS AND SYSTEM USAGE

Cellular customers come from a wide range of demographic segments. Business
users typically include a large proportion of individuals who work outside of
their offices such as people in the construction, real estate, wholesale and
retail distribution businesses and professionals. Increasingly, U.S. Cellular is
providing cellular service to consumers and to customers who use their cellular
telephones for mixed business and personal use as well as for security purposes.
A major portion of U.S. Cellular's recent customer growth is from these lower
revenue segments. Although some of U.S. Cellular's customers still use
in-vehicle cellular telephones, most new customers are selecting portable
cellular telephones. These units have become more compact and fully featured as
well as more attractively priced, and they appeal to newer segments of the
customer population.

U.S. Cellular's cellular systems are used most extensively during normal
business hours between 7:00 AM and 6:00 PM. On average, the local retail
customers in U.S. Cellular's consolidated markets used their cellular systems
approximately 105 minutes per unit each month and generated retail revenue of
approximately $33 per month during 1998, compared to 103 minutes and $36 per
month in 1997. Revenue generated by roamers using U.S. Cellular's systems
("inbound roaming"), together with local retail, toll and other revenues,
brought U.S. Cellular's total average monthly service revenue per customer unit
in consolidated markets to $49 during 1998. Average monthly service revenue per
customer unit decreased approximately 10% during 1998. This decrease resulted
from decreases in average revenue per minute of use from both local retail
customers and inbound roamers. Competitive pressures and U.S. Cellular's
increasing use of pricing and other incentive programs that encourage weekend
and off-peak usage at reduced rates, in order to stimulate overall usage,
resulted in a decrease in average local retail revenue per minute of use in
1998. Although the introduction of "one rate" pricing plans by other wireless
companies has helped increase inbound roaming minutes of use on U.S. Cellular's
systems during 1998, the inbound roaming revenue per minute has decreased during
the year. The decrease is partially a result of the ongoing trend toward reduced
per minute prices for roaming negotiated between U.S. Cellular and other
cellular operators and also due to the additional minutes generated by customers
with "one rate" pricing plans, which are at lower than average rates. U.S.
Cellular anticipates that average monthly service revenue per customer unit will
continue to decline in the future. However, this effect is more than offset by
U.S. Cellular's increasing number of customers; therefore, U.S. Cellular expects
total revenues to continue to grow for the next few years.

13
U.S. Cellular's main sources of revenue are from its own customers and from
inbound roaming customers. U.S. Cellular's roaming service allows a customer to
place or receive a call in a cellular service area away from the customer's home
service area. U.S. Cellular has entered into "roaming agreements" with operators
of other cellular systems covering virtually all systems in the United States,
Canada and Mexico. U.S. Cellular also has roaming agreements with several PCS
operators. The charge for this service is typically at premium rates and is
billed by U.S. Cellular to the customer's home system, which then bills the
customer. U.S. Cellular has entered into agreements with other cellular carriers
to transfer roaming usage at agreed-upon rates. In some instances, based on
competitive factors, U.S. Cellular may charge a lower amount to its customers
than the amount actually charged to U.S. Cellular by another cellular carrier
for roaming.

The following table summarizes certain information about customers and
market penetration in U.S. Cellular's consolidated operations.

PRODUCTS AND SERVICES

CELLULAR TELEPHONES AND INSTALLATION. There are a number of different types
of cellular telephones, all of which are currently compatible with cellular
systems nationwide. U.S. Cellular offers a full range of vehicle-mounted,
transportable and portable cellular telephones. Features offered in some of the
cellular telephones include hands-free calling, repeat dialing, horn alert and
others. In the systems where U.S. Cellular offers digital service, additional
features such as caller ID and short messaging services are available on those
cellular telephones.

U.S. Cellular negotiates volume discounts from its cellular telephone
suppliers. U.S. Cellular discounts cellular telephones to meet competition or to
stimulate sales by reducing the cost of becoming a cellular customer. In these
instances, where permitted by law, customers are generally required to sign a
service contract with U.S. Cellular. U.S. Cellular also cooperates with cellular
equipment manufacturers in local advertising and promotion of cellular
equipment.

U.S. Cellular has established service and/or installation facilities in many
of its local markets to ensure quality installation and service of the cellular
telephones it sells. These facilities allow U.S. Cellular to improve its service
by promptly assisting customers who experience equipment problems. Additionally,
U.S. Cellular maintains a repair facility in Tulsa, Oklahoma, which handles more
complex service and repair issues.

14
CELLULAR SERVICES.  U.S. Cellular's customers are able to choose from a
variety of packaged pricing plans which are designed to fit different calling
patterns. The ability to help a customer find the right technology and the right
pricing plan is central to U.S. Cellular's brand positioning. During 1998, U.S.
Cellular focused its efforts on new products with the continued introduction of
its digital service offering, called Digital PCS, and its prepaid offering,
TalkTracker-Registered Trademark-. Both offerings were very successful, as many
higher revenue customers purchased U.S. Cellular's digital offering and new
market segments such as individuals with credit difficulties, were able to
purchase cellular service through U.S. Cellular's prepaid offering. U.S.
Cellular's customer bills typically show separate charges for custom-calling
features, airtime in excess of the packaged amount, and toll calls.
Custom-calling features provided by U.S. Cellular include wide-area call
delivery, call forwarding, call waiting, three-way calling and no-answer
transfer. U.S. Cellular also offers a voice message service in many of its
markets. This service, which functions like a sophisticated answering machine,
allows customers to receive messages from callers when they are not available to
take calls. Additional services, such as short messaging services, are available
in U.S. Cellular's markets where digital service is offered.

REGULATION

REGULATORY ENVIRONMENT. The operations of U.S. Cellular are subject to FCC
and state regulation. The cellular telephone licenses held by U.S. Cellular are
granted by the FCC for the use of radio frequencies and are an important
component of the overall value of the assets of U.S. Cellular. The construction,
operation and transfer of cellular systems in the United States are regulated to
varying degrees by the FCC pursuant to the Communications Act of 1934 (the
"Communications Act"). In 1996, Congress enacted the Telecommunications Act of
1996 (the "1996 Act"), which amended the Communications Act. The 1996 Act
mandates significant changes in existing telecommunications rules and policies
to promote competition, ensure the availability of telecommunications services
to all parts of the nation and to streamline regulation of the
telecommunications industry to remove regulatory burdens, as competition
develops. The FCC has promulgated regulations governing construction and
operation of cellular systems, licensing (including renewal of licenses) and
technical standards for the provision of cellular telephone service under the
Communications Act, and is implementing the legislative objectives of the 1996
Act, as discussed below.

LICENSING. For cellular telephone licensing purposes, the FCC has divided
the United States into separate geographic markets (MSAs and RSAs). In each
market, the allocated cellular frequencies are divided into two equal blocks.
During the application process, the FCC reserved one block of frequencies for
non-wireline applicants and another block for wireline applicants. Subject to
FCC approval, a cellular system may be sold to either a wireline or non-wireline
entity, but no entity which controls a cellular system may own an interest in
another cellular system in the same MSA or RSA.

The completion of acquisitions involving the transfer of control of a
cellular system requires prior FCC approval. Acquisitions of minority interests
generally do not require FCC approval. Whenever FCC approval is required, any
interested party may file a petition to dismiss or deny the application for
approval of the proposed transfer.

The FCC must be notified each time an additional cell is constructed which
enlarges the service area of a given market. The FCC's rules also generally
require persons or entities holding cellular construction permits or licenses to
coordinate their proposed frequency usage with neighboring cellular licensees in
order to avoid electrical interference between adjacent systems. The height and
power of base stations in the cellular system are regulated by FCC rules, as are
the types of signals emitted by these stations. In addition to regulation by the
FCC, cellular systems are subject to certain Federal Aviation Administration
("FAA") regulations with respect to the siting and construction of cellular
transmitter towers and antennas as well as local zoning requirements.

Beginning in 1996, the FCC has also imposed a requirement that all licensees
register and obtain FCC registration numbers for all of their antenna towers
which require prior FAA clearance. All new towers must be registered at the time
of construction and existing towers were required to be registered on a
staggered state-by-state basis, by May 1998. U.S. Cellular has completed the
registration of its existing towers.

15
Beginning in October 1997, cellular systems, which previously were
"categorically excluded" from having to evaluate their facilities to ensure
their compliance with federal "radio frequency" (RF) radiation requirements,
were made subject to those requirements (all cellular towers of less than 10
meters in height, building mounted antennas and cellular telephones must comply
with RF radiation guidelines). After October 1997, all new cellular facilities
must be in compliance when they are brought into service. Existing facilities
must be brought into compliance with the requirements when their licenses are
renewed. U.S. Cellular believes that the great majority of its existing
facilities already comply with the requirements, the remainder will be brought
into compliance as required and that the cellular telephones it sells comply
with the standards.

Initial cellular telephone licenses were granted for ten-year periods. The
FCC has established standards for conducting comparative renewal proceedings
between a cellular licensee seeking renewal of its license and challengers
filing competing applications. The FCC has: (i) established criteria for
comparing the renewal applicant to challengers, including the standards under
which a renewal expectancy will be granted to the applicant seeking license
renewal; (ii) established basic qualifications standards for challengers; and
(iii) provided procedures for preventing possible abuses in the comparative
renewal process. The FCC has concluded that it will award a renewal expectancy
if the licensee has (i) provided "substantial" performance, which is defined as
"sound, favorable and substantially above a level of mediocre service just
minimally justifying renewal," and (ii) complied with FCC rules, policies and
the Communications Act. If a renewal expectancy is awarded to an existing
licensee, its license is renewed and competing applications are not considered.
All of U.S. Cellular's licenses which it applied to have renewed in 1995, 1996,
1997, and 1998 were renewed.

U.S. Cellular conducts and plans to conduct its operations in accordance
with all relevant FCC rules and regulations and anticipates being able to
qualify for a renewal expectancy in its upcoming renewal filings. Accordingly,
U.S. Cellular believes that current regulations will have no significant effect
on its operations and financial condition. However, changes in the regulation of
cellular operators or their activities and of other mobile service providers
could have a material adverse effect on U.S. Cellular's operations.

The FCC has also provided that five years after the initial licenses are
granted, unserved areas within markets previously granted to licensees may be
applied for by both wireline and non-wireline entities and by third parties.
Accordingly, many unserved area applications have been filed by U.S. Cellular
and others and have generally been routinely granted. U.S. Cellular's strategy
with respect to system construction in its markets has been to build cells
covering areas within such markets that U.S. Cellular considers economically
feasible to serve or might conceivably wish to serve and to do so within the
five-year period following issuance of the license. In cases where applications
for unserved areas are filed which are mutually exclusive and would result in
overlapping service areas, the FCC decides between the competing applicants by
an auction process.

Pursuant to 1993 amendments to the Communications Act, cellular service is
classified as a Commercial Mobile Radio Service ("CMRS"), in that it is service
offered to the public, for a fee, which is interconnected to the public switched
telephone network. The FCC has determined that it will forebear from requiring
CMRS carriers to comply with a number of statutory provisions otherwise
applicable to common carriers, such as the filing of tariffs.

RECENT EVENTS. There are certain regulatory proceedings currently pending
before the FCC which are of particular importance to the cellular industry. In
one proceeding, the FCC has imposed new "enhanced 911" regulations on cellular
carriers. Enhanced 911 capabilities will enable cellular systems to determine
the precise location of persons making emergency calls. The new rules will
require cellular carriers to work with local public safety officials to process
911 calls, including those made from mobile telephones not registered with the
cellular system. Since April 1998, cellular carriers have had to be able to
identify the cell from which the call has been made. The rules will require
cellular systems to improve their ability to locate wireless 911 callers by
2001.

The FCC has adopted a limited expansion of the obligation of cellular
carriers to serve the roaming subscribers of broadband PCS providers, among
others, even though the subscribers involved have no pre-existing service
relationship with that carrier. Under these new policies, broadband PCS
providers

16
may offer their subscribers handsets which are capable of operating over
broadband PCS and cellular networks so that when their subscribers are out of
range of broadband PCS networks, they will be able to obtain non-automatic
access to cellular networks. The FCC expects that implementation of these
roaming capabilities will promote competition between broadband PCS and cellular
service providers.

The FCC has adopted requirements which will make it possible for subscribers
to retain, subject to certain geographic and other limitations, their existing
telephone numbers when they switch from one service provider to another. This
numbering portability will include switching between Local Exchange Carriers
("LECs") and other wireline providers, between wireless service providers and
between LEC/ wireline and wireless providers. LECs, in the 100 largest MSAs, had
implementation deadlines by the end of 1998 at those switches which received
specific requests for numbering portability. The FCC recently extended the
compliance date for cellular, broadband PCS, and certain other wireless
providers to November 2002.

In another proceeding, the FCC in 1996 adopted rules regarding the method by
which cellular carriers and LECs shall compensate each other for interconnecting
cellular and local exchange facilities. The FCC rules provided for symmetrical
and reciprocal compensation between LECs and cellular carriers, and also
prescribed interim interconnection proxy rates, which are much lower than the
rates formerly paid by cellular carriers to LECs. Symmetrical and reciprocal
compensation means they must pay each other at the same rate. Interconnection
rate issues will be decided by the states. Cellular carriers are now paying and
in the future can be expected to pay lower rates to LECs than they previously
paid. This result is expected to be favorable to the wireless industry and
somewhat unfavorable to LECs.

The FCC is also proceeding to implement other parts of the 1996 Act. The
1996 Act provides that implementing its legislative objectives will be the task
of the FCC, the state public utilities commissions and a Federal-state Joint
Board. Much of this implementation is proceeding in numerous, concurrent
proceedings with aggressive deadlines. The Company cannot predict the full
extent of, nature of and interrelationships among state and federal
implementation and other responses to the 1996 Act.

The primary purpose and effect of the new law is to open all
telecommunications markets to competition. The 1996 Act makes most direct or
indirect state and local barriers to competition unlawful. It directs the FCC to
preempt all inconsistent state and local laws and regulations, after notice and
comment proceedings. It also enables electric and other utilities to engage in
telecommunications service through qualifying subsidiaries.

Only narrow powers over competitive entry are left to state and local
authorities. Each state retains the power to impose competitively neutral
requirements that are consistent with the 1996 Act's universal service
provisions and necessary for universal services, public safety and welfare,
continued service quality and consumer rights.

The 1996 Act establishes principles and a process for implementing a
modified "universal service" policy. This policy seeks nationwide, affordable
service and access to advanced telecommunications and information services. It
calls for reasonably comparable urban and rural rates and services. The 1996 Act
also requires universal service to schools, libraries and rural health
facilities at discounted rates. Cellular carriers must provide such discounted
rates in accordance with federal regulations. The FCC has implemented the
mandate of the 1996 Act to create a new universal service support mechanism "to
ensure that all Americans have access to telecommunications services." The 1996
Act requires all interstate telecommunications providers, including wireless
service providers, to "make an equitable and non-discriminatory contribution" to
support the cost of providing universal service, unless their contribution would
be de minimis. At present, the provision of landline telephone service in high
cost areas is subsidized by access charges and other payments by interexchange
carriers to LECs. The obligation to make payments to support universal service
has been expanded to include other telecommunications service providers,
including cellular carriers. Such payments, based on a percentage of the total
"billed revenue" of carriers for a given previous half year and began in the
first quarter of 1998. Carriers are free to pass such charges on to their
customers. Cellular carriers are also eligible to receive universal service
support payments in certain circumstances under the new systems if they provide
specified services in "high cost" areas. U.S. Cellular has sought designation as
an "eligible telecommunications carrier" qualified to receive universal service
support in certain states.

17
Under a 1994 federal law, the Communications Assistance to Law Enforcement
Act, all telecommunications carriers, including U.S. Cellular and other wireless
licensees, were to have implemented, by October 1998, certain equipment changes
necessary to assist law enforcement authorities in achieving an enhanced ability
to conduct electronic surveillance of those suspected of criminal activity.
However, owing to disputes between the Federal Bureau of Investigation and the
relevant industry groups about the law's requirements, the FCC has not yet
adopted the necessary technical standards to enable carriers to meet those
requirements. Questions also exist regarding reimbursement by a federal fund of
certain of the costs involved. U.S. Cellular supported the efforts of industry
groups to obtain from the FCC a postponement of the October 1998 deadline on the
grounds that compliance with the originally proposed schedule was impossible. In
September 1998, the FCC postponed the compliance deadline until June 2000.

The FCC also has pending proceedings: (1) to ensure that the customers of
wireless providers, among others, receive complete, accurate, and understandable
bills; (2) to establish safeguards to protect against authorized access to
customer information; (3) to retain, relax or repeal its 45 megahertz ("MHz")
cap on the amount of spectrum which entities under common ownership and control
may hold in a single market and its related cellular cross-interest
restrictions; and (4) to implement requirements for wireless providers to set
interstate interexchange rates in each state at levels no higher than the rates
charged to subscribers in any other state.

The FCC has also allocated a total of 140 MHz to broadband PCS, 20 MHz to
unlicensed operations and 120 MHz to licensed operations, consisting of two 30
MHz blocks in each of the 51 Major Trading Areas ("MTAs") and one 30 MHz block
and three 10 MHz blocks in each of 493 Basic Trading Areas ("BTAs"). Cellular
operators and those entities under common ownership with them are permitted to
participate in the ownership of PCS licenses, except for those PCS licenses
reserved for small businesses, and licenses for PCS service areas in which the
cellular operator owns a 20% or greater interest in a cellular licensee, the
service area of which covers 10% or more of the population of the PCS service
area. In the latter case, the cellular license is limited to two 10 MHz PCS
channel blocks. As noted previously, the FCC is now reconsidering these
ownership limits.

PCS technology is similar in some respects to cellular technology. Where it
has become commercially available, this technology is capable of offering
increased capacity for wireless two-way and one-way voice, data and multimedia
communications services and has resulted in increased competition with U.S.
Cellular's operations in the markets where PCS systems have begun operations.
The ability of these PCS licensees to complement or compete with existing
cellular licensees will be affected by future FCC rule-makings. These and other
future technological and regulatory developments in the wireless
telecommunications industry and the enhancement of current technologies will
likely create new products and services that are competitive with the services
currently offered by U.S. Cellular. There can be no assurance that U.S. Cellular
will not be adversely affected by such technological and regulatory
developments.

STATE AND LOCAL REGULATION. U.S. Cellular is also subject to state and
local regulation in some instances. In 1981, the FCC preempted the states from
exercising jurisdiction in the areas of licensing, technical standards and
market structure. In 1993, Congress preempted states from regulating the entry
of cellular systems into service and the rates charged by cellular systems to
customers. The siting and construction of the cellular facilities, including
transmitter towers, antennas and equipment shelters are still subject to state
or local zoning and land use regulations. However, in 1996, Congress amended the
Communications Act to provide that states could not discriminate against
wireless carriers in tower zoning proceedings and had to decide on zoning
requests with reasonable speed. In addition, states may still regulate other
terms and conditions of cellular service.

The FCC is required to forbear from applying any statutory or regulatory
provision that is not necessary to keep telecommunications rates and terms
reasonable or to protect consumers. A state may not apply a statutory or
regulatory provision that the FCC decides to forbear from applying. In addition,
the FCC must review its telecommunications regulations every two years and
change any that are no longer necessary. Further, the FCC is empowered under
certain circumstances to preempt state regulatory authorities if a state is
obstructing the Communications Act's basic purposes.

18
U.S. Cellular and its subsidiaries have been and intend to remain active
participants in proceedings before the FCC and state regulatory authorities.
Proceedings with respect to the foregoing policy issues before the FCC and state
regulatory authorities could have a significant impact on the competitive market
structure among wireless providers and the relationships between wireless
providers and other carriers. U.S. Cellular is unable to predict the scope, pace
or financial impact of policy changes which could be adopted in these
proceedings.

COMPETITION

U.S. Cellular's principal competitor for cellular telephone service in each
market is the licensee of the second cellular system in that market. Since each
competitor operates its cellular system on a 25 MHz frequency block licensed by
the FCC using comparable technology and facilities, competition for customers
between the two systems in each market is principally on the basis of quality of
service, price, size of area covered, services offered, and responsiveness of
customer service. The competing entities in many of the markets in which U.S.
Cellular has an interest have financial resources which are substantially
greater than those of U.S. Cellular and its partners in such markets.

The FCC's rules require all operational cellular systems to provide, on a
nondiscriminatory basis, cellular service to resellers which purchase blocks of
mobile telephone numbers from an operational system and then resell them to the
public.

In addition to competition from the other cellular licensee in each market,
there is also competition from PCS providers and ESMR system providers, both of
which are able to connect with the landline telephone network. PCS providers
have initiated service in many markets across the United States, including
markets where U.S. Cellular has operations. PCS providers offer digital,
wireless communications services to their customers. U.S. Cellular expects PCS
operators to continue deployment of PCS in portions of all of U.S. Cellular's
clusters throughout 1999. ESMR, an enhanced SMR system, has cells and frequency
reuse like other wireless services, thereby eliminating any technological
limitation. In recent years, ESMR providers have initiated service in several of
U.S. Cellular's markets. Although less directly a substitute for cellular
service, wireless data services and paging services may be adequate for those
who do not need full two-way voice service. Similar technological advances or
regulatory changes in the future may make available other alternatives to
cellular service, thereby creating additional sources of competition.

Continuing technological advances in the communications field make it
difficult to predict the extent of additional future competition for cellular
systems. For example, the FCC has allocated radio channels to a mobile satellite
system in which transmissions from mobile units to satellites would augment or
replace transmissions to cell sites, and several consortia to provide such
service have been formed. Such a system is designed primarily to serve the
communications needs of remote locations and a mobile satellite system could
provide viable competition for land-based cellular systems in such areas. It is
also possible that the FCC may in the future assign additional frequencies to
cellular telephone service to provide for more than two cellular telephone
systems per market.

TELEPHONE OPERATIONS

OVERVIEW

The Company's telephone operations are conducted through TDS Telecom and its
subsidiaries. TDS Telecom is a full-service local exchange carrier providing
high-quality telecommunication services, including local and long-distance
telephone service and Internet access, to rural and suburban communities through
TDS Telecom's 105 telephone company subsidiaries. Each of these telephone
companies, ranging in size from less than 500 to more than 60,000 access lines,
is an Incumbent Local Exchange Carrier ("ILEC"). TDS Telecom served
approximately 547,500 access lines through its ILEC subsidiaries at December 31,
1998, in 28 states.

The table below sets forth, as of December 31, 1998, (i) the nine largest
states of operations of TDS Telecom based on the number of access lines and (ii)
the total number of access lines operated by all of the telephone subsidiaries
of TDS Telecom.

TDS Telecom provides consumers and businesses with landline local telephone
service through its switching and intra-city network. Long-distance or toll
service is provided through connections with long-distance carriers, primarily
AT&T and the Regional Bell Operating Companies ("RBOCs"), which purchase network
access from TDS Telecom. In 1998, TDS Telecom began providing telecommunications
services as a Competitive Local Exchange Carrier ("CLEC") in Madison, Appleton,
Green Bay, Menasha and Neenah, Wisconsin under the TDS METROCOM brand name and
in Minnesota markets including Brainerd, Duluth and St. Cloud under the USLink
brand name. TDS Telecom served approximately 38,800 customers through its CLEC
subsidiaries at December 31, 1998.

Future growth in telephone operations is expected to be derived from
providing service to new or presently unserved establishments, from business
expansion in the areas served by TDS Telecom and others, from upgrading existing
customers to higher grades of service, from increased usage of the network
through both local and long-distance calling, from providing additional services
made possible by advances in technology and from the acquisition of additional
telephone companies.

TDS Telecom is committed to offering its customers a full complement of
telecommunications services, and is bundling those services in customer friendly
packages in order to become a single source for their telecommunications needs.
TDS Telecom intends to provide its customers with an ever-growing range of
communications products and services covering their local, long distance, data,
video and wireless needs. In 1998, TDS Telecom grew its competitive market
offerings with products and services such as cellular telephone service (in
partnership with U.S. Cellular), Personal Number Services, Prepaid Calling
Cards, and a Commercial DISH Network (digital broadcast satellite) product.

(1) An "access line" is a single or multi-party circuit between the customer's
establishment and the central switching office.

TDS Telecom is a wholly-owned business unit of TDS, founded in 1968. TDS
Telecom's corporate headquarters are located in Madison, Wisconsin.

BUSINESS STRATEGY

TDS Telecom has historically produced revenue growth in its ILEC markets by
providing its customers with state-of-the-art telecommunications solutions,
maintaining a high quality of on-going service and selectively acquiring local
telephone companies. Management believes that TDS Telecom has a number of
advantages as an ILEC, including (i) a modern network substantially upgraded to
provide a variety of Advanced Calling Services ("ACS"), (ii) a strong local
presence and established brand name, (iii) economies of scale not available to
smaller independent operators and (iv) attractive, growing markets. However, the
competitive environment in the telecommunications industry has changed
significantly as a result of technological advances, increasing customer
requirements and regulatory changes, including the Telecommunications Act of
1996 ("the 1996 Act"). In response to this changing competitive environment, TDS
Telecom's business plan is designed to leverage TDS Telecom's strength as an
ILEC into a full-service telecommunications company. The business plan provides
for TDS Telecom to meet these challenges in three areas: (i) by growing and
protecting TDS Telecom's core ILEC business, (ii) by leveraging its strengths
into attractive new markets, and (iii) by creating a robust line of data
products and services, and selling them in existing and new markets.

GROW AND PROTECT CORE ILEC BUSINESS

Management of TDS Telecom believes that the key to growing and protecting
its existing ILEC markets is to continue to build customer loyalty by providing
superior customer service, offering a suite of standardized products and
services, including bundled service offerings, and rapidly developing new
products and services. Management of TDS Telecom believes that its
community-based business offices offering full face-to-face customer service are
a fundamental competitive advantage. That advantage was further enhanced in 1998
when TDS Telecom rolled out its Virtual Business Office ("VBO") initiative,
which links multiple business offices electronically, permitting TDS Telecom to
maintain its local presence while expanding hours and achieving certain
efficiencies of a consolidated call center. With respect to products and
services, TDS Telecom markets itself to consumers as a single telecommunications
provider offering bundled packages of advanced telecommunications services
including local, long distance, Internet and data services. These service
packages are all offered under the TDS Telecom

21
brand name in order to benefit from the brand equity in this name. In addition,
management of TDS Telecom believes it can achieve cost economies by refining its
acquisition strategy to focus on certain acquisitions which will increase the
geographic clustering of TDS Telecom's ILEC markets. See "--ILEC Telephone
Markets".

LEVERAGE STRENGTHS INTO CLEC MARKETS

TDS Telecom has begun its controlled entry into certain targeted midsized
communities, geographically proximate to existing TDS Telecom facilities and
service areas, for facilities-based entry as a CLEC (a term which depicts
companies that enter the operating areas of traditional telephone companies).
Management of TDS Telecom believes that the smaller size of these markets
reduces the likelihood of facing significant competition and it can offer a
significantly improved service level over that of the ILEC. Because it can
utilize the infrastructure (e.g. billing systems, network control center,
operating systems, financial and control accounting, technology planners, etc.)
built for the ILEC business, management believes that TDS Telecom can become
profitable in markets too small for start-ups and become profitable faster than
start-ups at the high end of its targeted range (about 200,000 population). As
in its ILEC markets, TDS Telecom intends to be the single source for customers'
telecommunications needs in its CLEC markets.

The geographic focus of TDS Telecom's CLEC strategy is designed to leverage
TDS Telecom's existing infrastructure to facilitate early entry into new CLEC
markets and to complement TDS Telecom's ILEC clustering strategy. Consistent
with this strategy, TDS Telecom initiated service as a CLEC in Madison,
Wisconsin, and in Brainerd, Duluth and St. Cloud, Minnesota, in January 1998 and
initiated service as a CLEC in Appleton, Green Bay, Menasha and Neenah,
Wisconsin, in June 1998. In Minnesota, TDS Telecom has adopted a slightly
different strategy by entering as a CLEC through its long-distance subsidiary,
USLink. USLink is able to build on its relationship developed as a long distance
reseller and now offers local and Internet access services to its long distance
customers in a number of locations in Minnesota. During 1999, USLink will be
converting customers in Brainerd, Duluth and St. Cloud to its facilities as part
of its long-term strategy. TDS Telecom plans to expand its CLEC operations to
additional markets if the results of operations in the aforementioned markets
prove successful. See "--CLEC Telephone Markets".

PURSUE EMERGING DATA MARKETS

Data communications is one of the fastest growing segments of the
telecommunications services industry. In light of the growth of Internet use and
rapid introduction of new telecommunications technology, TDS Telecom intends to
offer a suite of data products in all of its markets, thereby positioning itself
as a full-service data networking service provider. TDS Telecom currently
provides Internet access service to its ILEC and CLEC customers. Most of TDS
Telecom's data products are in the early stages of development. See "--Data
Initiatives".

ILEC TELEPHONE MARKETS

TDS Telecom's goal is to be a leading provider of electronically deliverable
products in its ILEC markets. According to published sources, at December 31,
1998 TDS Telecom was the 9th largest non-Bell local exchange telephone company
in the United States, based on the number of telephone access lines served. At
December 31, 1998, the telephone subsidiaries of TDS Telecom served
approximately 547,500 access lines in 28 states. TDS Telecom currently operates
over 435 central office and remote switching centers in its telephone operating
areas. Substantially all of TDS Telecom's access lines are served by digital
switching technology, which, in conjunction with other technologies, allows TDS
Telecom to offer additional premium services to its customers, including call
forwarding, conference calling, caller identification, selective call ringing
and call waiting. At December 31, 1998, TDS Telecom's telephone subsidiaries
also provided Internet services to approximately 4,000 customers.

As one of the major independent telephone companies in the United States,
TDS Telecom's ILECs provide both local telephone service and access to the long
distance network for customers in their respective service areas. The ILECs also
provide directory advertising through a contract with another

22
company and billing and collection services to interexchange carriers ("IXCs").
TDS Telecom provides centralized administrative and support services to field
operations from its corporate offices in Madison, Wisconsin.

RETAIL MARKETS

TDS Telecom's ILEC presence includes a Retail Markets Group and Wholesale
Markets Group. The Retail Markets Group is the customer-facing organization for
all retail sales with residential and commercial customers. The Retail Markets
Group includes 119 sales and service offices located in 28 states. The retail
customer base is a mix of rural and suburban customers, with significant
concentrations in the Upper Midwest and in the Southeast. Approximately 78% of
TDS Telecom's retail access lines serve residential customers and approximately
22% serve business customers. Most business customers could be described as
small business or small office/home office type customers.

The Retail Markets Group has three primary goals to support its grow and
protect strategy: (i) build customer loyalty, (ii) grow revenues, and (iii)
control costs. Management of TDS Telecom believes it can achieve these goals by
offering a continually updated flow of new products and services through value-
added packages and bundles, by building brand equity in the TDS Telecom brand
name, and by providing superior customer service to its retail customers.

VALUE ADDED PRODUCT BUNDLES AND PACKAGES. Management of TDS Telecom
believes that its consumer and business customers have a strong preference to
purchase all of their telecommunications services from a single provider. TDS
Telecom believes that by offering a full complement of telecommunication
services and bundling those services in customer-friendly packages it can build
customer loyalty and reduce customer churn. TDS Telecom added several new
services in 1998 by combining the services of its network with the services of
carefully selected strategic partners. These products include: cellular
telephone service (in partnership with U.S. Cellular), Personal Number Services,
Prepaid Calling Cards, and a Commercial DISH Network (digital broadcast
satellite) product. These products were sold both as stand-alone items and as
part of value-added product bundles and packages. TDS Telecom will continue to
pursue relationships with strategic partners to further develop the long
distance, video and wireless components of its product mix.

BRAND EQUITY. TDS Telecom continued the branding process started in 1996.
This process adopted the TDS Telecom name as a unified brand name across its
ILEC markets to build its brand image. TDS Telecom has continued its customer
awareness campaign to build awareness of the TDS Telecom name. TDS Telecom
continues to build name awareness through existing customer-facing vehicles such
as bill statements, and vehicle and company signage. Centralized media
purchasing has enabled higher reach and frequency at a lower cost. In 1998, TDS
Telecom focused on building a positive share of mind with current and
prospective customers. This was done by increasing the volume of public
relations messages and through linkage of company image with sales and marketing
messages. The strategy will continue through 1999. Management of TDS Telecom
believes that branding will increase the loyalty of its customers and also
reduce expenses through more cost-effective marketing.

CUSTOMER SERVICE. TDS Telecom makes a unique customer service offer to its
retail customers. TDS Telecom is a large national company with a local sales and
service office in each of its ILEC markets. This combination provides TDS
Telecom's retail customers with the economies of scale and product offers
generally associated with large companies. It also provides the high levels of
personal customer service generally associated with small companies, through
community-based professional service representatives and field representatives
who both live and work in the communities served. TDS Telecom's strength in two
key areas--product/price and customer service-- provides a fundamental
competitive advantage for TDS Telecom.

TDS Telecom began deploying a Virtual Business Office ("VBO") initiative in
1998. This initiative enables multiple local sales and service offices to
function as a single office. Management of TDS Telecom believes that VBO will
facilitate enhanced customer service at a lower cost. Cost savings are expected
to come through standardization of training and procedures and improved voice
and customer service application technology. Enhanced customer service will come
through expanded hours of

23
operation, improved product, service and sales training for all customer sales
and service representatives, and through improved customer access to company
personnel on the first call. Initial customer surveys show that customer
satisfaction with transactions in the VBO environment is equal to or better than
satisfaction with transactions in the prior environment. TDS Telecom plans to
complete deployment of VBO in 1999.

WHOLESALE MARKETS

The Wholesale Markets Group focuses on TDS Telecom's wholesale customers and
has traditionally provided a majority of TDS Telecom's revenues. TDS Telecom
receives much of its ILEC revenue from the sale of traditional wholesale
services, such as access service charges and billing and collections services to
the IXCs. As a result, TDS Telecom continues to provide a high level of service
to traditional IXC wholesale customers such as AT&T, MCI, Sprint and the RBOCs.

ACCESS REVENUES. TDS Telecom's operating telephone subsidiaries receive
access revenue as compensation for carrying interstate and intrastate
long-distance traffic on its network. The interstate and intrastate access rates
charged include the cost of providing service plus a fair rate of return. Access
revenues account for approximately 56% of the revenue generated by TDS Telecom's
ILEC subsidiaries.

TDS Telecom participates in the National Exchange Carrier Association
("NECA") interstate common line and traffic sensitive tariffs for all but one of
its ILEC subsidiaries. These operating companies participate in the access
revenue pools administered by NECA, which collect and distribute revenue from
interstate access services. The FCC created NECA and it is subject to FCC rules
and oversight.

The FCC regulates interstate toll rates and other matters relating to
interstate telephone service. On June 4, 1998, the FCC released a Notice of
Proposed Rulemaking (NPRM) on access reform for local exchange carriers subject
to rate of return regulation. In the NPRM, the FCC proposed changes similar to
those which were ordered for price cap local exchange carriers ("LECs") in 1997.
The proposed changes could negatively affect rural LECs' ability to recover
costs from the interstate jurisdiction. The FCC also released an NPRM on
jurisdictional separations reform on October 7, 1997. In the NPRM, the FCC
reviewed the current procedures for separating LECs' service costs between state
and federal jurisdictions. Many of the proposals in the NPRM seek to limit costs
assigned to the interstate jurisdiction and seek to assign greater costs to the
intrastate jurisdiction. To the extent that the costs are not made up in the
federal and state universal service mechanisms, TDS Telecom may seek rate
increases to offset any reductions in interstate revenues. The FCC has not yet
issued a final order on either of these two NPRMs.

TDS Telecom is also monitoring the effects of increasing volumes of Internet
traffic on the operating telephone subsidiaries' ability to appropriately
recover the network-related costs associated with this traffic. Unless changes
to the access charge methodology and/or to the separations process are made,
increasing costs will continue to be shifted to the intrastate jurisdiction for
recovery and TDS Telecom may need to seek rate increases to recover these costs.

Where applicable and subject to state regulatory approval, TDS Telecom's
ILEC subsidiaries utilize intrastate access tariffs and participate in
intrastate revenue pools. However, many intrastate toll revenue pooling
arrangements, a source of substantial revenues to TDS Telecom's ILECs, have been
replaced with access-charge-based arrangements. In these cases, access charges
are typically set to generate revenue flows similar to those realized in the
pooling process. To the extent that state-ordered access charge revisions reduce
revenues, TDS Telecom may seek adjustments in other rates. Some states are
utilizing a state high cost fund to offset access charge reductions.

FEDERAL FINANCING

TDS Telecom's primary sources of long-term financing for additions to
telephone plant and equipment have been the Rural Utilities Service ("RUS"), the
Rural Telephone Bank ("RTB") and the Federal Financing Bank ("FFB"), agencies of
the United States of America. The RUS has made primarily 35-year loans to
telephone companies since 1949, at interest rates of 2% and 5%, for the purpose
of improving telephone service in rural areas. Currently, the RUS is authorized
to issue hardship loans at a 5% interest

24
rate and other loans at an interest rate approximating the government's rate for
instruments of comparable maturity. The RTB, established in 1971, makes loans at
interest rates based on its average cost of money (5.71% for its fiscal year
ended September 30, 1998), and in some cases makes loans concurrently with RUS
loans. In addition, the RUS guarantees loans made to telephone companies by the
FFB at the federal cost of money. All such loans have a maturity date based on
the life of the assets being financed.

Substantially all of TDS Telecom's telephone plant is pledged under, or is
otherwise subject to, mortgages securing obligations of the operating telephone
companies to the RUS, RTB and FFB. The amount of dividends on common stock that
may be paid by the operating telephone companies is limited by certain financial
requirements set forth in the mortgages. In any calendar year, companies with
greater than 40% net worth to total assets can distribute the entire amount
above 40%. The majority of TDS Telecom's telephone subsidiaries exceed this
percentage. Approximately $400.9 million may be paid as dividends from the
operating subsidiaries to TDS Telecom and TDS.

At December 31, 1998, TDS Telecom's operating telephone companies had
unadvanced loan commitments under the RUS, RTB and FFB loan programs aggregating
approximately $116.4 million, at a weighted average annual interest rate of
5.10%, to finance specific construction activities in 1999 and future years.
These loan commitments are generally issued for five-year periods and may be
extended under certain circumstances. TDS Telecom's operating telephone
companies intend to make further applications for additional loans from the RUS,
RTB and FFB as their needs arise. There is no assurance that these applications
will be accepted or what the terms or interest rates of any future loan
commitments will be.

FEDERAL SUPPORT REVENUES

To promote universal service, the FCC developed a number of federal support
mechanisms to keep telephone rates affordable for both high-cost rural areas and
low-income customers. Many of TDS Telecom's ILEC subsidiaries provide telephone
service in rural areas and all of them offer service to low-income customers.

The 1996 Act codified universal service; set forth principles for ensuring
affordable access to modern telephone service nationwide; established discounts
for schools, libraries and rural health care facilities; and established a
federal-state joint board to make recommendations to the FCC regarding
implementation of the universal service provisions of the 1996 Act. On May 8,
1997, the FCC released its Order on universal service, adopting many of the
joint board's recommendations. The FCC adopted the use of forward-looking proxy
cost models to determine costs rather than relying on actual costs. However,
rural LECs will continue to receive support based on their actual costs through
at least December 31, 2000. Rural LECs will then transition to another method of
receiving support if it can be shown that the method will be sufficient to meet
the universal service needs of customers in the areas they serve. Proceedings to
resolve additional universal service issues, including what ILEC or CLEC lines
can receive support, petitions for reconsideration and judicial appeals of
portions of the FCC's universal service rules and policies remain pending.

The FCC's Order also mandated that all telecommunications providers
contribute to the universal service fund beginning January 1, 1998. However, the
Order allows LECs to recover these contributions through their interstate access
rates.

The final rules to implement the universal service provisions of the 1996
Act will involve development of new support mechanisms and changes in the
eligibility criteria. In addition, some of TDS Telecom's LEC subsidiaries
operate in states where support and rate structures are either being
re-evaluated or have already been changed. Full recovery of universal service
costs in the future through interstate and intrastate mechanisms is uncertain.
If interstate or intrastate support decreases, TDS Telecom's LEC subsidiaries
may pursue local service rate increases to recover the difference.

Historically, telephone company acquisition and investment decisions assumed
the ability to recover the cost and a reasonable rate of return through local
service, access and support revenues. Significant changes in the universal
service funding system could affect TDS's and TDS Telecom's acquisition and
investment strategy.

25
TELEPHONE ACQUISITIONS

TDS and TDS Telecom continually review attractive opportunities to acquire
operating telephone companies. Since January 1, 1994, TDS has acquired 16
telephone companies serving a total of 77,100 net access lines for an aggregate
consideration totaling $238.1 million, all of which were transferred to TDS
Telecom. The consideration paid by TDS consisted of $27.3 million in cash and
notes, 155,000 TDS Preferred Shares and 4.4 million TDS Common Shares. TDS sold
one telephone company serving 1,100 access lines in 1995.

Telephone holding companies and others actively compete for the acquisition
of telephone companies and such acquisitions are subject to the consent or
approval of regulatory agencies in most states and, in some cases, to federal
waivers that may affect the form of regulation or amount of interstate cost
recovery of acquired telephone exchanges. The Company has modified its
acquisition strategy to focus on geographic clustering of telephone companies to
achieve cost economies and to complement TDS Telecom's growth strategy. While
management believes that it will be successful in making additional
acquisitions, there can be no assurance that TDS or TDS Telecom will be able to
negotiate additional acquisitions on terms acceptable to it or that regulatory
approvals, where required, will be received.

It is TDS Telecom's policy to preserve, in so far as possible, the local
management of each telephone company it acquires. TDS Telecom provides the
telephone subsidiaries with centralized purchasing and general management and
other services, at cost plus a reasonable rate of return on invested capital.
These services afford the subsidiaries expertise in finance, accounting and
treasury services; marketing; customer service; traffic; network management;
engineering and construction; customer billing; rate administration; credit and
collection; and the development of administrative and procedural practices.

CLEC TELEPHONE MARKETS

The 1996 Act facilitates entry of TDS Telecom into new markets by requiring
non-exempted ILECs (e.g., RBOCs and GTE) to provide reasonable and
non-discriminatory interconnection services and access to unbundled network
elements to any CLEC that seeks to enter the markets in which the ILEC already
offers services. TDS Telecom, through TDS METROCOM and USLink, wholly owned
subsidiaries of TDS Telecom, has targeted certain midsized communities,
geographically proximate to existing TDS Telecom facilities and service areas
for facilities-based entry as a CLEC. Management of TDS Telecom believes that
the size of the target markets will sustain one or two facilities-based
competitors in addition to the ILEC. While additional competitors may enter such
markets as resellers, TDS Telecom believes only facility-based CLECs will be
profitable over the long term because facilities will provide a long-run cost
advantage, discourage further competitors from entry and enable an alternative
wholesale strategy for growth. To this end, TDS Telecom plans to build switching
and other network facilities in its targeted CLEC markets. TDS Telecom plans to
follow a "clustering" approach to building its CLECs which will allow it to seek
regional long distance traffic, share service and repair resources, and realize
marketing efficiencies. As in its ILEC markets, TDS Telecom intends to become an
Integrated Communications Provider ("ICP") in its chosen CLEC markets. It will
provide local, long distance, Internet access and other services through its own
facilities and via resale. TDS Telecom intends to resell mobile services in many
markets. TDS Telecom's CLEC strategy is currently focused on third-tier cities
in Wisconsin and Minnesota.

TDS Telecom's first CLEC in Madison, Wisconsin, became operational in
January 1998. The Madison CLEC is a facilities-based, full-service alternative
to Ameritech and Mid-Plains Telephone Companies, providing both voice and data
services to commercial and consumer accounts, as well as wholesale services to
IXCs and other carriers. TDS Telecom also began CLEC operations in Appleton,
Green Bay, Menasha and Neenah, Wisconsin. USLink began offering local service
(in addition to its long distance and Internet products) on a resale basis in
1998 in Minnesota, with a focus on the Brainerd, St. Cloud and Duluth markets.
USLink plans to deploy local facilities in these markets during 1999 to enhance
the operating margins. TDS Telecom will consider expanding into other markets if
the results of operations in the aforementioned markets prove successful.

26
The CLEC strategy will place primary emphasis on the small and medium-sized
commercial and wholesale customers such as Internet Service Providers ("ISP's"),
cellular, paging and PCS companies. Consumer markets will be pursued
approximately six months after the CLEC enters the commercial market. Wholesale
customers purchase transmission capacity and access services from CLECs. These
services will be available to wholesale customers shortly after network
completion. TDS Telecom believes that these customers are generally more
sophisticated and are more likely to switch providers to obtain network
reliability, redundancy and more flexible pricing. Medium-sized commercial
prospects are characterized by above-average access line to employee ratios,
heavier utilization of data services, and a focus on using telecommunications
for business improvement rather than on cost reduction concerns. The companies
are generally growth-oriented and may be underserved by the ILEC or major IXCs.
TDS Telecom will pursue a personal selling approach for its primary target
markets. This approach builds on customer preference for integrated
communication services and the customer's perception that the quality of the
product is in the personalized service.

While the CLEC is positioning itself as a high-quality provider, it expects
price competition from the ILECs as they attempt to retain and regain their
customers. The CLEC will seek to maintain an efficient cost structure to ensure
it can match price-based initiatives from competitors. The ILEC is likely to be
constrained in the short term by the existing regulatory environment; as a
result, TDS Telecom expects to be more flexible in responding to customer needs.
To effectively compete in this new environment, TDS Telecom will enhance its
efforts at product development to provide high-quality, cutting-edge services to
its customers.

TDS Telecom believes the targeted third-tier markets present a significant
opportunity to market data services, as the major carriers serving these
locations have typically underinvested in these markets despite the growing
demand. Switched data communications represents one of the fastest growing
segments of the telecommunications services market. Computer proliferation,
connectivity via local and wide area networks, the Internet and the emergence of
multimedia applications are all driving demand. As a result, the domestic
network infrastructure is strained at both the local and national levels. TDS
Telecom's CLEC initiative will add local capacity in its selected cities
designed to accommodate this growth.

DATA INITIATIVES

TDS Telecom is also seeking to recognize additional revenue opportunities in
adjacent areas of the telecommunications industry. In 1998, TDS Telecom
continued to expand its investments into data communications to offer a suite of
data products in its CLEC and in many of its ILEC markets. TDSNET, TDS Telecom's
Internet service provider, expanded its operation in 1998 to serve approximately
43,000 customers at December 31, 1998. As of December 31, 1998, TDS Telecom
integrated its Internet and developing data services into existing products and
services offered by its ILEC and CLEC business units. Alignment of the company's
growing Internet product line into its core business units, coupled with sales
and marketing strategies focused on in-territory and nearby markets, will allow
TDS Telecom to continue its Internet sales growth while benefiting from
operational and financial synergies. The FCC has proposed to reduce the dominant
carrier regulation on an ILEC's advanced network capabilities, but only if the
ILEC's basic telephone services and advanced operations follow strict standards
for structural and operational separation. During 1998, management determined
that the TDS Datacom structured wiring business did not fit well with the
Company's other lines of business and subsequently TDS Datacom was disposed of
through a combination of sales and market closings.

In furtherance of TDS Telecom's strategy to position itself as a
full-service, networking service provider, it plans to make high-speed Digital
Subscriber Loop ("DSL") based services available to customers in several of its
ILEC markets. TDS Telecom believes DSL technology will form the foundation for
new, high-speed data services and applications and has conducted trials of DSL
modems manufactured by several vendors. The first commercial offering of DSL
began in Wisconsin in 1998. This technology will be employed to offer high-speed
Internet access as well as high-speed LAN connectivity to remote users. In
addition, TDS Telecom plans to offer Frame Relay and asynchronous transfer mode
("ATM") services in select markets. TDS Telecom is expanding its business
offerings to include web hosting services and customized web content development
for various sized market segments. TDS

27
Telecom also plans to attract new Internet customers by offering Internet access
appliances. TDS Telecom is a provider of enterprise network management center
("ENMC") services to large businesses and government through expanded use of its
own network management facilities, and its knowledgeable personnel. Such
services would consist of centralized network monitoring as well as network
management. In 1997, the State of Wisconsin awarded TDS Telecom the "BadgerNet"
ENMC multi-year contract. The BadgerNet ENMC has been designed to provide a
focal point for the operational management of over 72 state agency and
university networks, services and equipment and began operations in 1998. TDS
Telecom believes it has developed substantial expertise in developing its ENMC
and has the capacity through existing facilities (and personnel) to provide ENMC
services to additional third parties.

Although TDS Telecom currently operates these businesses, they are in an
early stage of development. There can be no assurance that TDS Telecom will
expand these businesses.

SALES AND MARKETING

TDS Telecom seeks to leverage its networks through sales and marketing
activities targeted at two separate customer groups: retail and wholesale.
Retail customers are composed primarily of residential customers, businesses,
government and institutional telecommunications users. Wholesale customers
consist of IXCs and information service providers such as commercial data
processing service providers and ISPs.

RETAIL MARKETS

COMMERCIAL MARKETS. Businesses account for approximately 22% of TDS
Telecom's access lines. TDS Telecom focuses its marketing on
information-intensive industries such as financial services, health services,
realty, hotels and motels, education and government. TDS Telecom uses its direct
sales force, targeted mailings, and telemarketing to sell products and services
to the commercial markets, which are segmented into tiers based on size and
strategic importance. Different sales and distribution channels are employed for
each segment. Account executives focus on the most profitable customers by
staying in contact with them on a regular basis. TDS Telecom employs an
aggressive compensation plan for its account executives targeted at revenue and
customer satisfaction results.

CONSUMER MARKETS. TDS Telecom's promotional and sales strategy consists of
two major initiatives: building brand equity by creating awareness of the TDS
Telecom brand name; and using direct marketing to sell specific products and
product groupings. Approximately 78% of TDS Telecom's total access lines are
residential. Approximately 25% of TDS Telecom's residential customers live in
rural areas, while the other 75% are located in suburban settings. The nature of
TDS Telecom's markets has historically made direct marketing more effective than
mass media such as radio and television. In addressing its consumer markets, TDS
Telecom has made extensive and aggressive use of direct mail. It has been more
selective, though still active, in the use of telemarketing as a means of
generating awareness, qualified leads, and actual sales. Newspaper is used as
well. Uniform branding has made the use of mass media more attractive, and TDS
Telecom has increasingly incorporated these elements into its media mix.

In nearly all of its markets, TDS Telecom offers the complete family of
custom calling services including call waiting, call forwarding, three-way
calling, and speed dialing. In 1998, TDS Telecom sold 10,200 residential second
lines, an increase of 37% over 1997. TDS Telecom's advanced calling services
("ACS") family of products is centered around Caller ID service. In 1998, the
ACS family of services were available to 89% of the lines in service compared to
78% in 1997. Penetration of Caller ID increased from 16% to 19% of lines
equipped, and aggregate penetration of ACS increased from 30% to 35% of lines
equipped.

WHOLESALE MARKETS

Access charges, billing and collection services and other primarily
traditional wholesale offerings generated $275 million, or approximately 60%, of
TDS Telecom's revenue for the year ended December 31, 1998. Wholesale customers
are currently serviced by account teams in Madison, Wisconsin, and

28
Knoxville, Tennessee. These teams manage and coordinate the purchasing of access
services by the major IXC's and RBOCs on a national basis.

TDS Telecom also provides new wholesale offerings to non-traditional
customers. TDS Telecom has targeted wireline and wireless telecommunications
service providers and select vertical markets.

COMPETITION

ILEC MARKETS

The 1996 Act has helped to introduce a new wave of competition in the
telecommunications industry. The 1996 Act embraced competition in
telecommunications as a national policy and also started the process of
deregulation. The 1996 Act requires ILECs to provide reasonable and non-
discriminatory interconnection services and access to unbundled network elements
to any CLEC that seeks to enter the markets in which the ILEC already offers
services. The 1996 Act also allows CLECs to co-locate network equipment on the
ILEC's premises and prevents ILECs and CLECs from unduly restricting each other
from use of facilities or information that would allow other organizations to
effectively compete with them. The FCC has proposed adding further
interconnection requirements to spur competitive broadband development.

All 105 TDS Telecom ILEC companies are exempt from many of the provisions of
the 1996 Act. Specifically, they are exempt from the requirements imposed on the
ILECs until they receive a bona fide request for interconnection and the state
commission lifts the exemption. This, coupled with the economics of competing in
lower population density markets, may delay certain forms of competition
occurring in TDS Telecom ILEC service areas while additional regulatory issues
are resolved. However, some TDS Telecom ILECs already face interconnection
requests, filed by potential competitors, and TDS Telecom believes there will
eventually be open entry into nearly every aspect of the telephone industry,
including local service, interstate and intrastate toll, switched and special
access services and customer premises equipment.

TDS Telecom expects competition in the telephone business to be dynamic and
intense as a result of the entrance of new competitors and the development of
new technologies, products and services. Increased competition is expected from
competitive access providers, IXCs, out-of-territory RBOCs and independent
telephone companies, niche entrepreneurs, cable and utility companies, and
wireless and satellite providers. To face this increasing competition, TDS
Telecom's strategy is to build customer loyalty by providing superior customer
service, offering a suite of standardized products and services bundled in
response to customer preferences, and rapidly developing new data products and
services.

In the long-run, TDS Telecom believes that the wireless companies pose the
most significant threat to the local exchange industry. Wireless providers are
also seeking universal service support in various rural markets. Although
traditional analog cellular radio service currently cannot match the features or
the clarity of communications provided via wireline networks, and as a result of
high error rates and speed limitations is not suitable for data transmission,
advances in digital cellular and PCS technology may permit wireless companies to
match the functionality and clarity of wireline communication and still allow
customers the mobility of traditional wireless service. As the emerging PCS
companies compete directly with established cellular radio companies, flat-rate
pricing alternatives may drive wireless rates towards or below wireline rates.
In order to minimize the impact of wireless competition, TDS Telecom is pursuing
wholesale service agreements with wireless companies to provide services to them
and expects to provide wireless services through resale in many of its markets.

CLEC MARKETS

In Wisconsin and Minnesota and in each location in which TDS Telecom expands
as a CLEC, TDS Telecom faces, and expects to continue to face, significant
competition from the ILECs which currently dominate their local
telecommunications markets. TDS Telecom will compete with the ILECs on the basis
of price, reliability, state-of-the-art technology, product offerings, route
diversity, ease of ordering and customer service. However, the ILECs have
long-standing relationships with their customers, may have the potential to
subsidize competitive services from monopoly service revenues, and benefit from

29
some favorable state and federal regulations. TDS Telecom will seek to achieve
parity with the ILECs to be able to provide a full range of local
telecommunications services.

Although the ILECs generally are subject to greater pricing and regulatory
constraints than CLECs, ILECs are achieving increased pricing flexibility for
their services as a result of, among other things, the 1996 Act. Existing
competition for private line, special access and local exchange services is
based primarily on quality, capacity and reliability of network facilities,
customer service, response to customer needs, service features and price, and is
not based on any proprietary technology. As a result of the technology used in
its networks, TDS Telecom may have cost and service quality advantages over some
currently available ILEC networks. In addition, TDS Telecom believes that, in
general, it will provide more attention and responsiveness to its customers than
will its ILEC competitors.

TDS Telecom may face competition from other CLECs and other potential
competitors in certain of the cities in which TDS Telecom plans to offers its
services. Many of TDS Telecom's existing and potential competitors have
financial, personnel and other resources significantly greater than those of TDS
Telecom. However, TDS Telecom believes that its strategy of targeting third-tier
cities (midsized communities), and its capital, technical and management
resources will enable it to achieve its strategic objectives.

In addition to the ILECs and other CLECs, potential competitors capable of
offering private line, special access and local exchange services include long
distance carriers, cable television companies, electric utilities, microwave
carriers, wireless telephone system operators, and private networks built by
large end users. Previous impediments to certain utility companies entering
telecommunications markets under the Public Utility Holding Company Act of 1935
were removed by the 1996 Act.

CONSTRUCTION AND DEVELOPMENT PROGRAM

In 1998, TDS Telecom continued its program of enhancing and expanding its
service providing network. TDS Telecom intends to meet competition by providing
its customers with high-quality telecommunications services and building its
network to take full advantage of advanced telecommunications technologies such
as Signaling System 7 ("SS7"), fiber optic fed Digital Serving Areas ("DSAs"),
Integrated Services Digital Network ("ISDN"), and ACS. The following table shows
that TDS Telecom continues to make these advanced features available to a large
majority of its customers:

<TABLE>
<CAPTION>
AS OF DECEMBER 31, 1998
---------------------------------------------
# OF EQUIPPED LINES % OF EQUIPPED LINES
-------------------- -----------------------
<S> <C> <C>
Signaling System 7................................................... 509,331 96%
Advanced Calling Services............................................ 509,331 96%
Integrated Services Digital Network.................................. 400,715 76%
</TABLE>

As TDS Telecom upgrades and expands its network, it is also standardizing
equipment and processes to increase efficiency and has centralized the
monitoring and management of its network to reduce costs and improve service
reliability. TDS Telecom formed strategic alliances with Lucent Technologies and
Siemens Telecom Networks to modernize and standardize TDS Telecom's switching
platform with the Lucent 5ESS-2000 and Siemens EWSD switches. This standardized
switching platform assisted TDS Telecom in implementing its
24-hour-a-day/7-day-per-week Network Management Center. The Network Management
Center continuously monitors the network in an effort to proactively identify
and correct network faults prior to any customer impact. The Network Management
Center is proactively monitoring 100% of TDS Telecom's network.

TDS Telecom's total 1999 capital budget is $120 million compared to actual
capital expenditures of $143.1 million in 1998 and $151.5 million in 1997. The
telephone capital additions budget for 1999 includes approximately $12 million
for current CLEC markets, $45 million for outside plant facilities and $35
million for switching facilities in the ILEC markets. Financing for the 1999
capital additions will be primarily provided by internally generated funds and
supplemented by federal long-term financing.

30
REGULATION

TDS Telecom's ILEC subsidiaries are regulated by state regulatory agencies
and TDS Telecom seeks to maintain positive relationships with these regulators.
Rate setting, including local rates, intrastate toll rates and intrastate access
charges, are subject to state commission approval in most states. The state
regulators also establish and oversee any state universal service funds. TDS
Telecom will continue to pursue necessary changes in rate structures to ensure
affordable rates and reasonable earnings.

State regulators can approve service areas, service standards, and
accounting methods. In some states, construction plans, borrowing, depreciation
rates, affiliated charge transactions and certain other financial transactions
are also subject to regulatory approval. States have traditionally regulated
entry into local markets by designating a single carrier to be the universal
service provider. However, the 1996 Act has almost completely pre-empted state
authority over market entry. Each state retains the power to impose
competitively neutral requirements that are consistent with the 1996 Act's
universal service provision and necessary for universal services, public safety,
and welfare, continued service quality and consumer rights. While a state may
not impose requirements that effectively function as barriers to entry, and the
FCC must pre-empt challenged state requirements if they impose such barriers to
entry, a state retains limited authority to regulate certain competitive
practices in rural telephone company service areas. Proceedings to pre-empt laws
and policies in several states are pending before the FCC.

The 1996 Act establishes a general duty for all telecommunications carriers,
including wireless providers, to interconnect with other carriers. Congress
prescribed a more specific list of interconnection requirements for all LECs
including resale, number portability, dialing parity, access to rights-of-way
and reciprocal compensation. The FCC recently ruled that Internet access traffic
is primarily interstate, but left in place negotiated contracts and state
arbitrated arrangements for local reciprocal compensation between ILECs and
CLECs that provide interconnecting links between ISPs and their customers, as
well as the existing exemption from interstate access charges applicable to
ISPs. Challenges to these non-interstate arrangements for interstate traffic
will now continue at the federal appellate court level.

Unless exempted, or granted suspension or modification, ILECs have
additional obligations: (a) to negotiate in good faith terms of interconnection;
(b) to comply with more detailed interconnection terms, including
non-discrimination and unbundling their network and service components so
competitors may use only those elements they choose for providing their
services; (c) to offer their retail services at wholesale rates to facilitate
resale by their competitors; and (d) to allow other carriers to place equipment
necessary for interconnection or access on their premises.

The FCC has adopted or is considering rules and policies implementing the
provisions of the 1996 Act. Many of the FCC determinations made to implement the
1996 Act and to facilitate competition in local service and other telephone
services involve investment and upgrades to TDS Telecom LEC networks, and impose
greater costs and obligations on ILECs than on their competitors. These
investments and upgrades include requirements to implement local number
portability so subscribers may change to competitors' services without changing
their telephone numbers, network signaling information that must be provided to
certain other carriers and pay phone providers, requirements for preventing
unauthorized use of customer information gained from providing telephone service
for other purposes, and other changes that require additional investments and
expenses. TDS Telecom is seeking to comply with these requirements or to obtain
the necessary suspensions or modifications where appropriate, while at the same
time also pursuing policies that provide a fair opportunity to recover its
costs. A new law also requires LECs to provide certain communications for law
enforcement purposes. The full cost and the adequacy of the government
compensation are not yet known, but the LEC industry is pursuing regulatory
policies that cover any shortfall in available government compensation. The FCC
is also exploring how to comply with the requirement in the 1996 Act for federal
and state authorities to encourage nationwide advanced broadband infrastructure
development that could require extensive additional investment.

As defined in the 1996 Act, all of TDS Telecom's ILEC subsidiaries qualify
as rural telephone companies. Therefore, they are exempted from the ILEC
interconnection requirements until they receive a bona fide request for
interconnection and the state commission lifts the exemption. The FCC has also
adopted extensive rules for state commissions to follow in mediating and
arbitrating interconnection negotiations between incumbent LECs and carriers
requesting interconnection, services or network

31
elements. The 1996 Act establishes deadlines, standards for state commission
approval of interconnection agreements and recourse to the FCC if a state
commission fails to act. A federal appellate decision striking down FCC pricing
regulations for interconnection and several rules that limited TDS Telecom
telephone companies' ability to obtain regulatory relief from stricter
interconnection requirements for incumbent telephone companies was taken to the
U.S. Supreme Court in petitions for certiorari. On January 25, 1999, the Supreme
Court overturned most of the Eighth Circuit Court of Appeals decision that the
FCC's interconnection rules unlawfully infringed upon state regulatory
jurisdiction. Among the rulings the Supreme Court struck down were decisions
that the FCC had unlawfully increased the showings and changed the burden of
proof for retaining a rural ILEC's interconnection exemption and had misread the
1996 Act to allow an ILEC's competitors to demand piece parts of interconnection
agreements negotiated by other competitors with ILECs without agreeing to the
overall terms of the agreement.

TDS Telecom seeks to maintain and enhance existing revenue streams despite
heightened earnings review activity by state regulators and the advent of local
exchange competition sparked by the 1996 Act. TDS Telecom is preparing for
competition even though its operating subsidiaries remain governed by state
regulators. For example, TDS Telecom is seeking the necessary pricing
flexibility to adjust its rate structures to a more competitive model. TDS
Telecom is also participating in state regulatory and legislative processes to
urge that any telecommunications reform measures treat rural areas fairly and
continue to provide sufficient contributions to high cost rural service areas to
keep TDS Telecom ILECs' rates affordable and allow for the continued development
of rural infrastructure. The ongoing changes in public policy due to numerous
court proceedings and the introduction of competition may affect the earnings of
the operating subsidiaries, and TDS Telecom is not able to predict the impact of
these changes.

While the majority of TDS Telecom's ILEC subsidiaries continue to operate in
a rate-of-return environment, a number of state commissions are negotiating, or
have agreed to, alternative regulation plans with LECs. Price regulation, the
most common form of alternative regulation, focuses on the price of
telecommunication services. TDS Telecom's ILEC subsidiaries in Alabama,
Arkansas, Michigan and Pennsylvania are currently operating in a price-regulated
environment, whereby the commissions in those states no longer review earnings.
For several years, the RBOCs and some of the nation's larger LECs have operated
under an FCC "price cap" plan, modified in 1997, where earnings can be increased
only through productivity improvements.

For 1998, TDS Telecom's telephone subsidiaries did not elect either price
caps or an alternative FCC plan, which was designed for smaller LECs. Instead,
the operating subsidiaries plan to continue to abide by traditional
rate-of-return regulation for interstate purposes, unless those regulatory
requirements are changed. Since approximately one-third of TDS Telecom's
telephone subsidiaries serve high-cost areas, important averaging mechanisms
associated with the NECA pooling process would be lost if TDS Telecom elected
either of the alternatives to traditional rate-of-return regulation. However,
the FCC periodically considers whether to initiate a proceeding to lower the
allowed rate-of-return for rate-of-return LECs. On October 5, 1998, the FCC
released a Public Notice initiating a proceeding to represcribe the authorized
rate of return for interstate services provided by ILECs. Currently, this rate
is set at 11.25%. Reduction of the interstate rate of return would have
detrimental effects on ILECs and may impact the ability of ILECs to continue to
invest in infrastructure and economic development. TDS Telecom, along with the
rural industry associations, believes that it is inappropriate for the FCC to
represcribe the rate of return at this time, and that represcription should not
occur until after the FCC resolves other pending issues including universal
service, access reform, and separations reform. If the FCC proceeds with the
represcription, TDS Telecom may potentially be faced with a lower allowed
interstate rate of return, a reduction in universal service funds, and
potentially higher local rates.

Access to affordable long-distance service in rural areas was achieved
because the FCC ordered AT&T to provide nationwide average rates. As a result of
increasing competition, the FCC lifted all regulations relating to AT&T's
interstate services in 1996. However, the 1996 Act preserves interstate toll
rate averaging and endorses a nationwide policy that interstate and intrastate
long-distance rates of all long-distance carriers should not be higher in rural
areas than in urban areas they serve. TDS Telecom will continue to monitor
regulatory activities at both the federal and state levels to ensure continued
affordable long-distance and local rates for even its most remote exchanges.

BROADBAND PCS OPERATIONS

The Company's broadband PCS operations are conducted through Aerial and its
subsidiaries. Aerial is a provider of Personal Communications Services in the
Minneapolis, Tampa-St. Petersburg-Orlando, Houston, Pittsburgh, Kansas City and
Columbus Major Trading Areas (collectively, the "PCS Markets"). The PCS Markets
include approximately 27.7 million population equivalents. Aerial has
constructed networks for its PCS Markets using Global System for Mobile
Communication ("GSM") technology. Aerial served 311,900 PCS telephones at
December 31, 1998. At December 31, 1998, Aerial had expanded its system coverage
to total more than 80% of the six MTAs' total population.

PCS is the term used to describe the wireless telecommunications services
that are offered by those companies that acquired licenses for radio spectrum
(frequency range 1850-1990 MHz) in the Federal Communications Commission ("FCC")
auctions and are the newest entrants in the wireless telecommunications market.
PCS competes directly with existing cellular telephone, paging and specialized
mobile radio services. PCS providers were the first in most markets to offer
mass market all-digital mobile networks. In addition, Aerial believes PCS
providers may be among the first to be able to offer mass market wireless local
loop applications, in competition with switched and direct access local
telecommunications services.

Aerial's strategic goal is to take full advantage of the potential of
wireless telecommunications. Aerial sees an opportunity for significant growth
in the wireless telecommunications market through the shift of existing wireless
usage patterns from applications focused on business use, special occasions and
emergencies to much broader applications for everyday use. Aerial is structured
to meet the increasingly competitive challenges of the wireless
telecommunications marketplace, and has a marketing-oriented approach focused on
serving its customers and their needs. Since 1983, the demand for wireless
telecommunications services has grown dramatically as cellular, paging and other
emerging wireless personal communications services have become widely available
and increasingly affordable.

During 1996 and early 1997, Aerial contracted for network equipment, billing
systems, support software and the equipment and services necessary to launch
service. Additionally during this period, Aerial completed the design for its
PCS networks, acquired and built out the switching centers serving each market,
leased and built out a National Operations Center, leased or purchased the cell
sites required to launch service and commenced zoning and building the sites.
The Columbus MTA launched service on March 27, 1997. Aerial's five remaining
MTAs launched service during the second quarter of 1997. Across all six markets,
Aerial launched with approximately 600 cell sites in service. Aerial had 1,180
cell sites in service by the end of 1998. The coverage of Aerial's PCS networks
includes the major metropolitan areas within the PCS Markets, as well as
portions of the major highway corridors extending out from those areas.

In November 1996, the Company entered into a Member Control Agreement
("Agreement") forming a joint venture with Rural Cellular Corporation ("RCC"),
called the Wireless Alliance, LLC ("WALLC"), to build out certain rural areas
covering approximately 925,000 population equivalents in the Minneapolis MTA.
Aerial has contributed 20 MHz of its Minneapolis MTA license covering certain
territories as defined in the Agreement in return for a 49% equity interest in
the joint venture. RCC built the network and is responsible for the ongoing
operations. The WALLC launched service on in 1998. The joint venture purchases
services such as network switching from Aerial. The network uses GSM technology.

On September 8, 1998, pursuant to the terms of a Purchase Agreement dated
June 1, 1998, Sonera Ltd. ("Sonera"), formerly Telecom Finland Ltd., made a $200
million investment in Aerial Operating Company, Inc. ("AOC"), a then
wholly-owned subsidiary of Aerial. Sonera purchased approximately 2.4 million
shares of common stock of AOC at a price of approximately $83 per share
representing a 19.4% equity interest in AOC. Sonera's equity ownership amount in
AOC is subject to adjustment based on Aerial's 20-day average stock price during
the three years commencing September 8, 1998. Depending on the level of increase
in the stock price, Sonera's ownership amount in AOC could decline to
approximately 15%. In addition, after five years Sonera's equity in AOC becomes
incrementally

33
exchangeable for equity in Aerial Communications, Inc. or, in certain
circumstances, incrementally exchangeable for equity in TDS or cash. See
"--Proposed Corporate Restructuring".

WIRELESS TELECOMMUNICATIONS INDUSTRY

OVERVIEW. Wireless service is currently available using analog or digital
technology. Traditionally wireless services transmitted voice and data signals
over analog-based networks by varying the amplitude or frequency of one
continuous electronic signal transmitted over a single radio channel. Analog
technology currently has several limitations, including inconsistent service
quality, lack of privacy, limited capacity and less reliability in transferring
data without errors. Aerial has chosen GSM, which utilizes a digital technology,
for use in the PCS Markets. 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 additional
capacity, along with improvements in digital protocols, allows digital-based
wireless technologies to offer new and enhanced services, such as greater call
privacy and more robust data transmission features, such as "mobile office"
applications (including facsimile, electronic mail and wireless connections to
computer/data networks, including the Internet).

PCS spectrum differs from existing cellular and specialized mobile radio
("SMR") spectrum in three basic ways: frequency, spectrum and geographic
division. PCS networks will operate in a higher frequency range (1850-1990 MHz)
compared to the cellular and SMR frequency (800-900 MHz). PCS is comprised of 30
or 10 MHz spectrum versus 25 MHz spectrum for cellular networks. As a result of
the improved capacity of the infrastructure and large allocation of spectrum in
the A, B and C PCS frequency Blocks, PCS will have more capacity for new
wireless services such as data and video transmission. Finally, the geographic
areas for PCS licenses are divided differently than for cellular licenses. PCS
is segmented among 51 MTAs and 493 Basic Trading Areas ("BTAs") as opposed to
cellular's 306 MSAs and 428 RSAs. An MTA license generally covers a much larger
geographic area than a BTA, MSA or RSA license.

OPERATION OF WIRELESS NETWORKS. Wireless service areas are divided into
smaller geographic areas called "cells", each of which contains an antenna and a
base transceiver station ("BTS") consisting of a low-power transmitter, a
receiver and signaling equipment. The cells are typically configured on a grid
in a honeycomb-like pattern, although terrain factors (including natural and
man-made obstructions) and signal coverage patterns may result in irregularly
shaped cells and overlaps or gaps in coverage. The BTS in each cell is connected
by microwave, fiber optic cable or telephone wires to a switching office
("mobile switching center" or "MSC"). The MSC controls the operation of the
wireless telephone network for its entire service area, performing inter-BTS
hand-offs, managing call delivery to handsets, allocating calls among the cells
within the network and connecting calls to local landline telephone systems or
to long-distance telephone carriers. Wireless service providers have
interconnection agreements with various local exchange carriers and
interexchange carriers, thereby integrating the wireless telephone network with
landline telecommunications systems. Because two-way wireless networks are

34
fully interconnected with landline telephone networks and long-distance
networks, customers can receive and originate both local and long-distance calls
from their wireless telephones.

The signal strength of a transmission between a handset and a BTS antenna
declines as the handset moves away from the BTS antenna. The MSC and the BTSs
monitor the signal strength of calls in process. When the signal strength of a
call declines to a predetermined level, the MSC may "hand off" the call to
another BTS that can establish a stronger signal with the handset. If a handset
leaves the service area of the wireless service provider, the call is
disconnected unless an appropriate technical interface is established to hand
off the call to an adjacent service provider's system.

Operators of wireless networks frequently agree to provide service to
customers from other compatible networks who are temporarily located or
traveling through the operator's service area. Such customers are called
"roamers." Agreements among network operators allocate revenues received from
roamers. With automatic roaming, wireless customers are preregistered in certain
networks outside their home service area and receive service automatically while
they are roaming. Other roaming features permit calls to a customer to follow
the customer into different networks, so that the customer will continue to
receive calls in a different network just as if the customer were within his or
her service area.

Wireless customers generally are charged separately for monthly access, air
time, long-distance calls and custom-calling features (although custom-calling
features may be included in monthly access charges in certain pricing plans).
Wireless network operators pay fees to local exchange and long-distance
telephone companies for access to their networks and toll charges based on
standard or negotiated rates. When wireless operators provide service to roamers
from other networks, they generally charge roamer air-time usage rates, which
usually are higher than standard air-time usage rates for their own customers,
and additionally may charge daily access fees. Special, discounted rate roaming
arrangements, often between neighboring operators who wish to stimulate usage in
their respective territories, provide for reduced roaming fees and no daily
access fees.

TECHNOLOGY

With GSM technology, Aerial offers easy-to-use, interactive menu-driven
phones, and advanced features such as caller identification and a smart card, as
well as more complex features such as text messaging, which allows the GSM
handset to function as a two-way messaging device. In the future, Aerial intends
to increasingly emphasize services which are expected to increase the size and
scope of the wireless market, such as wireless data and information services as
well as wireless local loop services. Aerial anticipates that PCS will
ultimately offer a competitive alternative to wireline telephone service as PCS
networks are constructed and PCS operators form strategic alliances.

GSM is not compatible with other PCS or cellular technologies. However,
compatibility can be achieved through the use of handsets that support multiple
technologies. Aerial expects that compatibility between GSM and the existing
analog cellular systems will be achieved with the use of dual-mode handsets.
Aerial expects to launch its dual-mode service in 1999.

To date, seventeen North American PCS companies are providing commercial GSM
service. GSM systems are currently in commercial operation in over 2,400 North
American cities with more than 3 million customers. Aerial anticipates that its
customers will be able to roam substantially throughout the United States,
either on other GSM-based PCS networks or by using dual-mode handsets that can
also be used on existing cellular networks.

Aerial is a member of the North American GSM Alliance LLC ("GSM Alliance"),
an all-digital wireless PCS network of U.S. and Canadian carriers. The GSM
Alliance was established to create a national network and develop seamless
wireless communications for customers, whether at home, away or abroad. The GSM
Alliance's collaborative efforts focus on serving the wireless customer
efficiently by addressing the areas of roaming, customer care, national
distribution and data communications. Aerial is also a member of the GSM Capital
Limited Partnership. The partnership was formed to make investments in companies
mainly engaged in the wireless communications industry using the GSM platform,
that are in a development or expansion stage, or whose securities trade in an
organized market. Aerial is also a part of the GSM North America consortium,
which is the North American interest

35
group for the GSM Association. Formed in 1995, GSM North America brings together
service providers and equipment manufacturers to identify and resolve issues
related to making GSM the premier PCS digital technology.

SOURCES OF EQUIPMENT

Aerial does not manufacture any of the GSM network equipment, handsets or
accessories ("equipment") used or anticipated to be used in its operations. The
equipment Aerial uses or anticipates to use is available from multiple sources,
and Aerial anticipates such equipment will continue to be available to Aerial in
the foreseeable future, consistent with normal manufacturing and delivery lead
times. As GSM uses an open system architecture, and due to the fact that GSM has
well-developed features, software systems and equipment that are available "off
the shelf", Aerial is able to design its GSM networks and systems without being
dependent upon any single manufacturing source. Nokia Telecommunications Inc.
has been Aerial's sole supplier of digital radio channel and switching
infrastructure equipment during the initial build-out of its PCS networks.
Aerial's current handset vendors are Nokia Mobile Phones, Inc., Motorola Inc.,
and Mitsubishi Wireless Communications, Inc.

PRODUCTS AND SERVICES

Aerial offers coverage in those areas of the PCS Markets where most of the
population lives and works. Subsequent construction of its PCS networks will
provide coverage which, in combination with roaming services as described above,
is competitive with that of current cellular operators. Aerial provides roaming
capabilities through agreements with other GSM and cellular operators.

Aerial's two primary sources of revenues are similar to those available to
other cellular system providers. Service revenue primarily consists of charges
for access, airtime and value-added services provided to Aerial's retail
customers who use the network operated by Aerial, and charges for long-distance
calls made on Aerial's systems. Service revenue also consists of charges to
customers of other wireless carriers who use Aerial's PCS network when roaming
(outcollect roaming revenue). Equipment sales revenue consists of the sale of
handsets and related accessories to retailers, independent agents and end user
customers. At December 31, 1998, Aerial had 311,900 customers. Service revenues
and equipment sales revenues totaled $123.6 million and $31.5 million,
respectively, for the year ended December 31, 1998.

Aerial provides the following services and features:

THE SMART CARD. GSM technology employs a Smart Card which contains a
microchip containing detailed information about a customer's service profile.
The Smart Card allows Aerial to initiate services or change a customer's service
package from a remote location. The Smart Card also allows customers to roam
onto other participating GSM-based networks by using their cards in handsets
compatible with the local network.

FEATURE-RICH HANDSETS. As part of its basic service package, Aerial
provides easy-to-use, interactive menu-driven phones that enable customers to
utilize the features available in a GSM network. These handsets primarily use
words and easy-to-use menus rather than numeric codes to operate handset
functions such as call-forwarding, call-waiting and text messaging.

SHORT TEXT MESSAGING. GSM technology allows for the capability to send and
receive short text messages, similar to two-way radio paging services. This
service allows Aerial to offer a quicker and less expensive form of wireless
communication when a full conversation is not necessary.

ENHANCED SECURITY. Aerial's service provides greater security from
eavesdropping and cloning than analog wireless service. Greater conversation
security is provided by the encryption code of the digital GSM signal. Greater
fraud protection is provided because GSM handsets require the use of a Smart
Card with a sophisticated authentication scheme, the replication of which is
virtually impossible.

As the market for wireless telecommunications services continues to develop,
Aerial expects to offer advanced wireless applications such as mobile data
services, wireless private branch exchange applications, wireless local loop
services and other individually customized wireless products and services.

36
MARKETING AND DISTRIBUTION

Aerial's marketing objective is to create demand for its PCS service by
clearly differentiating its service offerings. Aerial believes the strength of
its marketing efforts is a key contributor to its success. Aerial has developed
overall marketing strategies as well as certain, specific local marketing
strategies for each PCS Market.

Aerial's mass marketing efforts emphasize the value of Aerial's services and
its "fairness" to customers and are supported by heavily promoting the Aerial
brand name. This is supported by a substantial advertising program.

Aerial offers its services and products through traditional cellular sales
channels as well as through new, lower cost channels which increase the quality
of the typical sale. Aerial utilizes traditional sales channels which include
mass merchandisers and retail outlets, company retail stores, sales agents and a
direct sales force. National distributors include Best Buy, Office Depot,
Staples and Ritz Camera. Aerial currently also distributes its services and
products through over 90 company retail locations (mall stores, strip mall
stores and kiosks). Based in part upon the remote activation feature of the GSM
Smart Card, Aerial also intends to develop distribution innovations such as
simplified retail sales processes and lower-cost channels which include inbound
telesales, affinity marketing programs, and via the Internet.

COMPETITION

The wireless telecommunications industry is experiencing significant
technological change, as evidenced by the increasing pace of digital upgrades to
existing analog cellular networks, evolving industry standards, ongoing
improvements in the capacity and quality of digital technology, shorter
development cycles for new products and enhancements, and changes in end-user
requirements and preferences. Accordingly, Aerial expects competition in the
wireless telecommunications business to be dynamic and intense as a result of
the entrance of new competitors and the development of new technologies,
products and services.

Aerial competes directly with up to five other PCS providers in each of its
PCS Markets. The other successful bidders in the FCC's broadband Block A and
Block B PCS auction in each of the six PCS Markets were PCS PrimeCo (Houston and
Tampa-St. Petersburg-Orlando), Sprint Spectrum (Minneapolis, Pittsburgh and
Kansas City) and AT&T Wireless Services, Inc. (Columbus). The existing cellular
providers in the PCS Markets, most of which have an infrastructure in place and
have been operational for a number of years, have, in most cases, upgraded their
networks to provide comparable services in competition with Aerial. Principal
cellular providers in the PCS Markets are AT&T Wireless Services, Inc.,
BellSouth Mobility, Inc., GTE Mobile Communications Corporation, AirTouch
Communications, Inc., Southwestern Bell, Bell Atlantic-NYNEX Mobile and
Ameritech Cellular. Additionally, the Company competes with SMR provider Nextel
Communications, Inc. in each of its six PCS Markets.

Aerial also competes with other communications technologies that now exist,
such as paging, enhanced specialized mobile radio ("ESMR") and global satellite
networks. In the future, cellular service and PCS will also compete more
directly with traditional landline telephone service providers and with cable
operators who expand into the offering of traditional communications services
over their cable systems.

All of such competition is intense. There can be no assurance that Aerial
will be able to compete successfully in this environment or that new
technologies and products that are more commercially effective than Aerial's
technologies and products will not be developed. In addition, many of Aerial's
competitors have substantially greater financial, technical, marketing, sales
and distribution resources than those of Aerial and have significantly greater
experience than Aerial in testing new or improved telecommunications products
and services and obtaining regulatory approvals. Some competitors are expected
to market other services, such as cable television access, with their wireless
telecommunications service offerings. Several of Aerial's competitors are
operating, or planning to operate, through joint ventures and affiliation
arrangements, wireless telecommunications networks that cover most of the United
States.

37
Aerial anticipates that market prices for two-way wireless services
generally will continue to decline in the future based on increased competition.
Aerial will compete to attract and retain customers principally on the basis of
services and enhancements, its customer service, the size and location of its
service areas and pricing. Aerial's ability to compete successfully will also
depend, in part, on its ability to anticipate and respond to various competitive
factors affecting the industry, including new services that may be introduced,
changes in consumer preferences, demographic trends, economic conditions and
discount pricing strategies by competitors, which could adversely affect
Aerial's operating margins.

REGULATION

REGULATORY ENVIRONMENT. The FCC regulates the licensing, construction,
operation and acquisition of wireless telecommunications systems in the United
States pursuant to the Communications Act of 1934, as amended, and the rules,
regulations and policies promulgated by the FCC thereunder. Under the
Communications Act, the FCC is authorized to allocate, grant and deny licenses
for PCS frequencies, establish regulations governing the interconnection of PCS
networks with wireline and other wireless carriers, grant or deny license
renewals and applications for transfer of control or assignment of PCS licenses,
and impose fines and forfeitures for any violations of FCC regulations.

In addition, the 1996 Act, which amended the Communications Act, mandates
significant changes in existing telecommunications rules and policies to promote
competition, ensure the availability of telecommunications services to all parts
of the nation and to streamline regulation of the telecommunications industry to
remove regulatory burdens, as competition develops, and makes regulation less
necessary. The FCC promulgated and continues to promulgate regulations governing
construction and operation of wireless carriers, licensing (including renewal of
licenses) and technical standards for the provision of PCS services under the
Communications Act, and is implementing the legislative objectives of the 1996
Act, as discussed below.

PCS LICENSING. The FCC established PCS service areas in the United States
and its possessions and territories based upon Rand McNally's market definition
of 51 MTAs comprised of 493 smaller BTAs. Each MTA consists of at least two
BTAs.

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 awarded for each MTA and substantially all
of the BTAs in every block, for a total of more than 1,500 licenses. This means
that in any PCS service area as many as six licensees could be operating
separate PCS networks. Under the FCC's rules, a broadband PCS licensee may own
combinations of licenses with total aggregate spectrum coverage of up to 45 MHz
in a single geographic area. The FCC adopted comprehensive rules that outlined
the bidding process, described the bidding application and payment process,
established penalties for certain bid withdrawals, default or disqualification
and established regulatory safeguards.

Several auction winners have filed for bankruptcy. Other winners tendered
approximately 450 licenses acquired in auctions to the FCC for cancellation in
1998. These licenses are scheduled to be reauctioned starting in March of 1999.

On November 9, 1995, in CINCINNATI BELL TELEPHONE CO. V. FCC (Case No.
94-3701/4113), the United States Court of Appeals for the Sixth Circuit granted
two petitions for review of an FCC order that had barred certain common
ownership of cellular and PCS interests in the same market, and remanded the
case to the FCC for further proceedings. Neither of the two petitioners had been
barred by cross interests from applying for any of the authorizations the FCC
later granted to Aerial. Aerial is watching the FCC proceedings closely.

The grants of licenses to Aerial are conditioned upon timely compliance with
the FCC's build-out requirements, I.E., coverage of one-third of the population
of a PCS market within five years of initial

38
license grant and coverage of two-thirds of that population within ten years.
Aerial has exceeded the buildout requirements for both the five year and ten
year stages for each of its MTAs.

The FCC also imposes a requirement that all licensees register and obtain
FCC registration numbers for all of their antenna towers which require prior FAA
clearance. All broadband PCS transmitting facilities of Aerial also must comply
with federal "radio frequency" (RF) radiation requirements. Aerial has complied
with and continues to comply with the antenna registration and RF radiation
requirements.

The FCC enhanced 911 ("E911") regulations require broadband PCS operators to
"be capable of transmitting 911 calls from individuals with speech or hearing
disabilities through the use of Text Telephone Devices ("TTY")." TTY equipment
currently, however, is not compatible with digital wireless systems such as
Aerial's. Consequently, on December 4, 1998, Aerial filed a petition with the
FCC requesting a waiver of the applicability of the TTY connectivity requirement
to Aerial's digital system. On December 30, 1998, the FFC granted Aerial, along
with over 100 other wireless operators, a temporary waiver of the regulation.
Equipment manufacturers are developing hardware and software that will make TTY
devices compatible with the digital wireless technologies used by Aerial and
other wireless service providers. Aerial is working with manufacturers and other
members of the wireless industry in developing solutions for users of TTY
devices.

The E911 regulations also require broadband PCS operators to determine the
approximate location of persons making the emergency calls. On February 5, 1999,
Aerial filed a petition requesting a waiver to clarify that handset based
location technology will meet the FCC's E911 location requirements. A waiver
will enable Aerial to be compliant with the location requirements by introducing
new handsets that have the capability of being located rather than installing
very expensive upgraded equipment throughout Aerial's entire network. Aerial's
waiver and dozens of other wireless operators' waiver requests are pending
before the FCC.

The FCC licenses granted to Aerial are issued for a ten-year period expiring
June 23, 2005 and may be renewed. In the event challengers file competing
applications in response to any of Aerial's renewal filings, the FCC has rules
and policies providing that the application of the licensee seeking renewal will
be granted and the application of the challenger will not be considered in the
event that the broadband PCS licensee involved has (i) provided "substantial"
service, which is defined as "sound, favorable and substantially above a level
of mediocre service just minimally justifying renewal" and (ii) substantially
complied with FCC rules, policies and the Communications Act. Although Aerial is
unaware of any circumstances which would prevent the approval of any future
renewal applications, there can be no assurance that Aerial's licenses will be
renewed by the FCC in the future. Moreover, although revocation and involuntary
modification of licenses are extraordinary regulatory measures, the FCC has the
authority to restrict the operation of licensed facilities or revoke or modify
licenses.

The FCC has proceedings in process which could open up other frequency bands
for wireless telecommunications and PCS-like services. There can be no assurance
that such proceedings will not result in additional wireless competition.

In addition, there are citizenship requirements, assignment requirements and
other federal regulations and requirements which may affect the business of
Aerial.

RECENT EVENTS. There are certain regulatory proceedings currently pending
before the FCC which are of particular importance to the broadband PCS industry.

The FCC is expected to give the telecommunications industry guidance as to
the implementation of the Communications Assistance for Law Enforcement Act
("CALEA"). Due to a conflict between manufacturing standards and law enforcement
requirements, the FCC extended the compliance date to June 30, 2000.

The FCC has adopted a limited expansion of the obligation of cellular
carriers to serve the subscribers of broadband PCS providers, among others, even
though neither the subscribers or the PCS providers involved have a pre-existing
service relationship with such cellular carrier. Under these new policies,
broadband PCS providers may offer their subscribers handsets which are capable
of operating over broadband PCS and cellular networks so that when their
subscribers are out of range of broadband

39
PCS networks, they will be able to obtain non-automatic access to cellular
networks. The FCC expects that implementation of these roaming capabilities will
promote competition between broadband PCS and cellular service providers. The
FCC is considering whether cellular, broadband PCS and certain SMR providers
instead should be required to provide "automatic" roaming service to other
providers (i.e., carrier-to-carrier roaming service) during a five year period
commencing after the last group of initial broadband PCS licenses are awarded,
which is expected to occur in 1999.

The FCC has adopted requirements which will make it possible for subscribers
to retain, subject to certain geographic and other limitations, their existing
telephone numbers when they switch from one service provider to another. This
numbering portability will include switching between LEC and other wireline
providers, between wireless service providers and between LEC/wireline and
wireless providers. LECs, in the 100 largest MSAs, had implementation deadlines
by the end of 1998 at those switches which received specific requests for
numbering portability. The FCC recently extended the compliance date for
cellular, broadband PCS, and certain other wireless providers to November 2002.

The FCC also has pending proceedings (1) to ensure that the customers of
wireless providers, among others, receive complete, accurate and understandable
bills, (2) to establish effective safeguards to protect against unauthorized
access to customer information, (3) to retain, relax or repeal its 45MHz
spectrum cap on the amount of broadband PCS and cellular spectrum which entities
under common ownership or control may hold in any single market and its related
cellular cross-interest restrictions, (4) to devise guidelines for the operation
and administration of universal service support mechanisms as applied to
wireless providers and (5) to implement requirements for wireless providers to
set rates for interstate interexchange services in each state at levels no
higher than the rates charged to subscribers in any other state.

The FCC is also continuing to implement the 1996 Act. The 1996 Act provides
that implementing its legislative objectives will be the task of the FCC, the
state public utilities commissions and a Federal-State Joint Board. Much of this
implementation has and continues to be proceeding in numerous, concurrent
proceedings with aggressive deadlines. Aerial cannot predict the full extent and
nature of developments of the 1996 Act, which will depend, in part, upon
interrelationships among state and federal regulators.

The primary purpose and effect of the 1996 Act is to open all
telecommunications markets to competition -- including local telephone service.
The 1996 Act makes most direct or indirect state and local barriers to
competition unlawful. It directs the FCC to preempt all inconsistent state and
local laws and regulations, after notice and comment proceedings. It also
enables electric and other utilities to engage in telecommunications service
through qualifying subsidiaries.

Only narrow powers over competitive entry are left to state and local
authorities. Each state retains the power to impose competitively neutral
requirements that are consistent with the 1996 Act's universal service provision
and necessary for universal services, public safety and welfare, continued
service quality and consumer rights.

The 1996 Act establishes principles and a process for implementing a
modified "universal service" policy. This policy seeks nationwide, affordable
service and access to advanced telecommunications and information services. It
calls for reasonably comparable urban and rural rates and services. The 1996 Act
also requires universal service to schools, libraries and rural health
facilities at discounted rates. In a series of orders adopted in 1997, the FCC
established universal service support mechanisms which require
telecommunications providers, including all wireless carriers, to contribute.
Aerial has made the required Universal Service Worksheet filings and makes the
required periodic payments.

Since enactment, the FCC has adopted orders implementing the local
competition provisions of the 1996 Act. The FCC found that broadband PCS and
certain other wireless providers that are entitled to reciprocal compensation,
may not be charged for LEC-originated traffic or for code opening/per-number
fees, and may obtain LEC interconnection subject to the terms of the 1996 Act.
Appeals were taken to the United States Supreme Court from these FCC orders by
numerous parties alleging that the FCC has exceeded its statutory mandate, among
other matters. On January 25, 1999, the U.S. Supreme Court upheld the FCC's
general jurisdiction to implement the local competition provisions of the 1996
Act.

40
STATE AND LOCAL REGULATION  The scope of state and local regulatory
authority covers such matters as the terms and conditions of interconnection
between LECs and wireless carriers with respect to intrastate services, customer
billing information and practices, billing disputes, other consumer protection
matters, facilities construction issues and transfers of control, among other
matters. In these areas, particularly the terms and conditions of
interconnection between LECs and wireless providers, the FCC and state
regulatory authorities share regulatory responsibilities with respect to
interstate and intrastate issues, respectively.

The FCC has pending numerous petitions for preemption of state and local
regulations which allege such regulations prohibit or impair the provision of
interstate or intrastate telecommunications services. It has also requested
public comment on a petition requesting preemption of moratoria imposed by state
and local governments on siting of telecommunications facilities, the imposition
of state taxes on the gross receipts of CMRS providers and other proposed state
taxes based on the asset value of CMRS licenses awarded by the FCC. The FCC has
been actively involved in educating state and local regulatory and zoning
authorities as to the prohibitions in the 1996 Act against the creation of
unreasonable and discriminatory zoning, taxation or other barriers to new
wireless providers.

The FCC is required to forbear from applying any statutory or regulatory
provision that is not necessary to keep telecommunications rates and terms
reasonable or to protect consumers. A state may not apply a statutory or
regulatory provision that the FCC decides to forbear from applying. In addition,
the FCC must review its telecommunications regulations every two years and
change any that are no longer necessary.

Aerial and its subsidiaries have been and intend to remain active
participants in proceedings before the FCC and before state regulatory and
zoning authorities. Proceedings with respect to the foregoing policy issues
before the FCC and state regulatory authorities could have significant impacts
on the competitive market structure among wireless providers and the
relationships between wireless providers and other carriers. Aerial is unable to
predict the scope, pace, or financial impact of policy changes which could be
adopted in these proceedings.

EMPLOYEES

The Notes to Consolidated Financial Statements, included in the Annual
Report, are an integral part of these statements.

Note A: The annual requirements for principal payments on long-term debt are
$248,000, $258,000, $270,000, $283,000 and $32.1 million for the years
1999 through 2003, respectively.

Note B: In 1998, TDS Capital II, a subsidiary trust ("Capital II") of TDS,
issued 6,000,000 of its 8.04% Company-Obligated Mandatorily Redeemable
Preferred Securities (the "1998 Preferred Securities") at $25 per
Preferred Security. Net proceeds totaled $144.9 million and were used to
reduce short-term debt. The sole asset of TDS Capital II is $154.6
million principal amount of TDS's 8.04% Subordinated Debentures due
March 31, 2038.

In 1997, TDS Capital I, a subsidiary trust ("Capital I") of TDS, issued
6,000,000 of its 8.5% Company-Obligated Mandatorily Redeemable Preferred
Securities (the "1997 Preferred Securities") at $25 per Preferred
Security. Net proceeds totaled $144.8 million and were used to reduce
short-term debt. The sole asset of TDS Capital I is $154.6 million
principal amount of TDS's 8.5% Subordinated Debentures due December 31,
2037.

The obligations of TDS Capital I and II under the 1998 Preferred
Securities and 1997 Preferred Securities (the "Preferred Securities")
issued by TDS Capital I and II are fully and unconditionally guaranteed
by TDS. However, TDS's obligations are subordinate and junior in right
of payment to certain other indebtedness of TDS. TDS has the right to
defer payments of interest on the Subordinated Debentures by extending
the interest payment period, at any time, for up to 20 consecutive
quarters. If interest payments on the Subordinated Debentures are so
deferred, distributions on the Preferred Securities will also be
deferred. During any deferral, distributions will continue to accrue
with interest thereon. In addition, during any such deferral, TDS may
not declare or pay any dividend or other distribution on, or redeem or
purchase, any of its common stock.

The 8.04% and 8.5% Subordinated Debentures are redeemable by TDS, in
whole or in part, from time to time, on or after March 31, 2003, and
November 18, 2002, respectively, or, in whole

51
but not in part, at any time in the event of certain income tax
circumstances. If the Subordinated Debentures are redeemed, TDS Capital
I and II must redeem Preferred Securities on a pro rata basis having an
aggregate liquidation amount equal to the aggregate principal amount of
the Subordinated Debentures so redeemed. In the event of the
dissolution, winding up or termination of TDS Capital I and II, the
holders of Preferred Securities will be entitled to receive, for each
Preferred Security, a liquidation amount of $25 plus accrued and unpaid
distributions thereon to the date of payment, unless, in connection with
the dissolution, winding up or termination, Subordinated Debentures are
distributed to the holders of the Preferred Securities.
