    As of February  28, 1997, the  aggregate market values  of the  registrant's
Common Shares, Series A Common Shares and Preferred Shares held by nonaffiliates
were  approximately $2.2 billion, $15.4 million and $40.8 million, respectively.
The closing price  of the Common  Shares on  February 28, 1997,  was $40.00,  as
reported by the American Stock Exchange. Because no market exists for the Series
A  Common Shares and  Preferred Shares, the registrant  has assumed for purposes
hereof that (i)  each Series  A Common  Share has a  market value  equal to  one
Common  Share because the  Series A Common  Shares were initially  issued by the
registrant in  exchange  for  Common  Shares on  a  one-for-one  basis  and  are
convertible   on  a  share-for-share   basis  into  Common   Shares,  (ii)  each
nonconvertible Preferred Share has a market  value of $100 because each of  such
shares  had  a stated  value of  $100  when issued,  and (iii)  each convertible
Preferred Share has a  value of $40.00  times the number  of Common Shares  into
which it was convertible on February 28, 1997.
 
    The  number of  shares outstanding  of each  of the  registrant's classes of
common stock,  as of  February 28,  1997, is  54,145,158 Common  Shares, $1  par
value, and 6,916,546 Series A Common Shares, $1 par value.

ITEM 1. BUSINESS
 
    Telephone  and Data Systems, Inc. (the "Company" or "TDS"), is a diversified
telecommunications service company  with established  cellular telephone,  local
telephone  and radio  paging operations  and developing  personal communications
services  ("PCS")  operations.  At  December   31,  1996,  the  Company   served
approximately  2.3  million customer  units  in 37  states,  including 1,073,000
cellular telephones, 484,500 telephone access lines and 777,400 pagers. For  the
year  ended December 31, 1996, cellular operations provided 58% of the Company's
consolidated revenues; telephone operations provided 33%; and paging  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 80.6%-owned subsidiary, United States Cellular Corporation [AMEX: USM]. U.S.
Cellular  provides cellular telephone service to 1,073,000 customers through 131
majority-owned   and   managed   ("consolidated")   cellular   systems   serving
approximately 16% of the geography and approximately 8% of the population of the
48  contiguous  United  States. Since  1985,  when the  Company  began providing
cellular service in Knoxville, Tennessee, the Company has expanded its  cellular
networks  and customer  service operations  to cover  140 managed  markets in 27
states as of December 31, 1996. In  total, the Company now operates nine  market
clusters,  of which five have  a total population of  more than two million, and
each of which has a  total population of more than  one million, plus one  other
unclustered  market.  Overall,  81%  of the  Company's  25.1  million population
equivalents are in  markets which are  consolidated, 1% are  in managed but  not
consolidated  markets  and 18%  are 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").
TDS  Telecom currently operates  105 telephone companies  serving 484,500 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 22 telephone companies and divested one
telephone  company since  the beginning  of 1992.  These net  acquisitions added
90,400 access lines during  this five-year period,  while internal growth  added
90,100 lines.
 
    The   Company  conducts   substantially  all   of  its   broadband  personal
communications services operations  through its  82.8%-owned subsidiary,  Aerial
Communications,  Inc. [NASDAQ:  AERL], formerly American  Portable Telecom, Inc.
[NASDAQ: APTI].  In March  1995,  Aerial was  the  successful bidder  for  eight
broadband  PCS  licenses.  The six  30  megahertz  PCS licenses  that  are being
developed
 
                                                                               3
<PAGE>
cover the  Major Trading  Areas  of Minneapolis,  Tampa-St.  Petersburg-Orlando,
Houston,  Pittsburgh, Kansas  City and  Columbus, and  account for  27.6 million
population equivalents.  Aerial has  sold  its licenses  covering the  Guam  and
Alaska MTAs.
 
    The  Company  conducts  substantially  all of  its  radio  paging operations
through its 82.3%-owned subsidiary, American Paging, Inc. [AMEX: APP].  American
Paging  offers radio paging and related services through its subsidiaries. Since
the beginning of 1992, the number of pagers in service increased from 236,800 to
777,400 at  December 31,  1996,  primarily from  internal growth.  APP  provides
service  in 21 states and the District  of Columbia through 51 sales and service
offices.  American  Paging's   service  areas  cover   a  total  population   of
approximately 76 million.
 
    The  Company  was  incorporated in  Iowa  in 1968.  The  Company's executive
offices are located  at 30 North  LaSalle Street, Chicago,  Illinois 60602.  Its
telephone number is 312-630-1900.

                         CELLULAR TELEPHONE OPERATIONS
 
    The Company's cellular  operations are conducted  through U.S. Cellular  and
subsidiaries.   U.S.   Cellular   serves   1,073,000   customers   through   131
majority-owned and managed cellular systems at December 31, 1996. Overall,  U.S.
Cellular owned 25.1 million population equivalents in 204 markets.
 
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
 
4
<PAGE>
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  and  radio paging.  PCS  has  become
available  in  certain areas  of the  United  States, including  U.S. Cellular's
markets, and U.S. Cellular expects PCS competitors to initiate service in all of
its markets in the  next one or two  years. Additionally, emerging  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 U.S. Cellular 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 are 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  available because technical standards require
that analog cellular telephones be compatible in all market areas in the  United
States.  The system  that provides  the service  to these  roamers will generate
usage revenue. Many operators, including U.S. Cellular, charge premium rates for
this roaming service.
 
    There are  a  number  of  recent  technical  developments  in  the  cellular
industry. Currently, while most of the MTSOs process information digitally, most
of  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 Tulsa, Oklahoma and its  Florida/Georgia
market  cluster.  Another  digital  technology,  Code  Division  Multiple Access
("CDMA"), is expected  to be  deployed by U.S.  Cellular in  a commercial  trial
during  1997. The Company  may also deploy  some CDMA digital  radio channels in
other markets on  a trial  basis in the  near future.  Digital radio  technology
offers  several advantages  including greater privacy,  less transmission noise,
greater system capacity and potentially  lower incremental costs for  additional
customers.  The conversion from analog to  digital radio technology has begun on
an industry-wide basis;  however this process  is expected to  take a number  of
years.
 
    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.
 
                                                                               5

CELLULAR OPERATIONS
 
    A significant portion of the aggregate  market value of TDS's Common  Shares
is  represented by the market value of TDS's interest in USM. From its inception
in 1983 until  1993, U.S.  Cellular has principally  been in  a start-up  phase.
Until  that time, 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  three years,  U.S. Cellular
generated operations-driven  net  income  and has  significantly  increased  its
operating  cash flows during that time. Management anticipates increasing 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 flow  and
operating  income during  the period  of accelerated  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  1994,
1995  and 1996,  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)
the introduction of competition  from PCS and  other emerging technologies;  and
(vi)   continuing   technological   advances  which   may   provide  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: Iowa,  Wisconsin/Illinois, Missouri,  Eastern
North  Carolina/South  Carolina, Virginia,  West Virginia/Maryland/Pennsylvania,
Oregon/California,  Washington/Oregon/Idaho,  Indiana/Kentucky/Ohio,   Maine/New
Hampshire/Vermont, Eastern Tennessee/Western North Carolina,
Oklahoma/Missouri/Kansas,   Texas/Oklahoma,  Florida/Georgia   and  Southwestern
Texas. See "U.S. Cellular's Cellular Interests." U.S. Cellular has acquired  its
cellular  interests through  the wireline  application process  (21%), including
settlements and exchanges with other applicants, and through acquisitions (79%),
including acquisitions from TDS and third parties.

    ACQUISITIONS.  During the  last five years, U.S.  Cellular has expanded  its
size, particularly in contiguous or adjacent markets, through acquisitions which
have  been  aimed  at strengthening  U.S.  Cellular's position  in  the cellular
industry. This growth has resulted  primarily from acquisitions of interests  in
mid-sized  and  rural markets  and has  been based  on obtaining  interests with
rights to manage the underlying market.
 
    U.S.  Cellular  has  increased  its  population  equivalents  by  31%   from
approximately  19.1 million at December 31,  1991, to approximately 25.1 million
at December 31, 1996.  Markets managed by U.S.  Cellular have increased from  91
markets  at  December 31,  1991,  to 140  markets at  December  31, 1996.  As of
December 31,  1996,  82% of  the  Company's population  equivalents  represented
interests in markets U.S. Cellular manages compared to 66% at December 31, 1991.
 
    Recently, the pace of acquisitions has slowed as industry-wide consolidation
has  reduced the  number of markets  available for  acquisition. U.S. Cellular's
population equivalents grew at a compound annual  rate of over 5% over the  last
five  years due to the increased number of exchange and divestiture transactions
in the past few years.
 
    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.  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

<PAGE>
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.
 
    U.S.  Cellular, or  TDS for the  benefit of U.S.  Cellular, has historically
negotiated acquisitions of  cellular interests from  third parties primarily  in
consideration for U.S. Cellular's or TDS's equity securities. Cellular interests
acquired  by TDS in these  transactions have been assigned  to U.S. Cellular. At
that time, U.S. Cellular reimbursed TDS  for the value of TDS securities  issued
in such transactions, generally by issuing Common Shares to TDS or by increasing
the  balance due TDS under U.S. Cellular's Revolving Credit Agreement in amounts
equal to the value of TDS securities delivered at the time the acquisitions were
completed. The fair market value of  the U.S. Cellular securities issued to  TDS
in  connection with these transactions was equal to the fair market value of the
TDS securities delivered in the transactions and was determined at the time  the
transactions were completed.
 
    In  the  past three  years, U.S.  Cellular  has also  negotiated substantial
divestitures and  exchanges  of  cellular  interests  with  third  parties.  The
consideration  received  from these  divestitures  of non-strategic  markets has
primarily been cash, which has been used to reduce debt or for general corporate
purposes. The exchanges have included  the divestiture of controlling  interests
in  non-strategic markets in exchange for controlling interests in markets which
further enhance U.S. Cellular's clusters.
 
    COMPLETED ACQUISITIONS.  During 1996, U.S. Cellular, or TDS for the  benefit
of  U.S. Cellular,  completed the  acquisition of  controlling interests  in two
markets and  several additional  minority interests  representing  approximately
400,000  population equivalents for an aggregate consideration of $56.1 million.
The consideration  consisted  of  1.1  million TDS  Common  Shares,  1,000  U.S.
Cellular  Common Shares and $13.6 million  in cash. U.S. Cellular reimbursed TDS
for TDS securities issued in the acquisitions through the issuance to TDS of 1.3
million U.S.  Cellular  Common  Shares.  U.S.  Cellular  also  acquired  several
minority  interests representing approximately 600,000  pops from TDS for $102.8
million in cash.
 
    COMPLETED DIVESTITURES AND EXCHANGES.  During 1996, U.S. Cellular  completed
the  divestiture  of  controlling interests  in  eight markets  plus  one market
partition and minority interests in two other markets representing approximately
1.2 million  population equivalents  for an  aggregate consideration  of  $176.5
million  in  cash.  Also  during  1996,  U.S.  Cellular  completed  an  exchange
transaction which resulted in the acquisition  of a controlling interest in  one
market,  representing 116,000 population equivalents, and the divestiture of one
market representing 97,000 population  equivalents. U.S. Cellular also  received
$11.3 million in cash pursuant to this exchange.
 
    PENDING  ACQUISITIONS, DIVESTITURES, AND  EXCHANGES.  At  December 31, 1996,
U.S. Cellular had entered into an  agreement to purchase a controlling  interest
in  one market  representing approximately 213,000  population equivalents. U.S.
Cellular has  also  entered into  an  agreement  with TDS  to  acquire  minority
interests  in two markets from  TDS representing 104,000 population equivalents.
These pending transactions are expected to be completed during 1997.
 
    In February  1997, U.S.  Cellular  announced that  it  had entered  into  an
exchange  agreement with BellSouth Corporation,  pursuant to which U.S. Cellular
will receive controlling interests in twelve contiguous markets adjacent to  its
Iowa  and Wisconsin/Illinois clusters. In exchange, U.S. Cellular will trade its
controlling interest in ten markets and  investment interests in 13 markets  and
pay cash, the amount of which is dependent upon certain factors. The transaction
is subject to various regulatory and other approvals.
 
    TDS and U.S. Cellular maintain shelf registration of their respective Common
Shares  and  Preferred Shares  under  the Securities  Act  of 1933  for issuance
specifically in connection with acquisitions.
 
    The Company has had  voting control of U.S.  Cellular since U.S.  Cellular's
incorporation.  TDS owned an  aggregate of 69,396,227 shares  of common stock of
U.S. Cellular at December 31, 1996, representing over 80% of the combined  total
of U.S. Cellular's outstanding Common and Series A Common Shares and over 95% of
their combined voting power.
 
                                                                               7

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
are not essential to its long-term strategies.
 
    U.S.  Cellular owned interests in cellular  telephone systems in 204 markets
at  December  31,  1996,  representing  25.1  million  population   equivalents.
Including the controlling interest to be acquired from a third party and the two
minority interests to be acquired from TDS, U.S. Cellular owned or had the right
to  acquire interests in  cellular telephone systems in  207 markets at December
31, 1996, representing 25.4 million population equivalents. The following  table
summarizes  the growth in U.S. Cellular's population equivalents in recent years
and the development status of these population equivalents.

(1)  Pursuant  to the  agreement  with BellSouth,  U.S.  Cellular has  agreed to
    transfer to BellSouth  a 100% interest  in these markets.  If U.S.  Cellular
    owns  less  than 100%  of these  markets at  the time  of completion  of the
    transaction, U.S.  Cellular  will pay  cash  to  BellSouth in  lieu  of  any
    interests U.S. Cellular does not own at the time.
 
(2)  In addition  to these  interests, U.S.  Cellular will  deliver to BellSouth
    interests in two markets which are currently owned by TDS.
 
(3) As a  result of  the transaction with  BellSouth, U.S.  Cellular expects  to
    divest its interest in these markets.
 
    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,  generally 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, primarily  analog radio transmission  is used between
cell sites and the cellular telephones themselves.
 
    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
or  has a right  to acquire 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 or microwave links
owned by others 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 both systems.
 
    U.S.  Cellular  has continued  to  expand its  internal  network in  1996 to
encompass all  of its  managed  markets. This  network provides  automatic  call
delivery for U.S. Cellular's customers and handoff between adjacent markets. The
network  has also been  extended through links with  certain systems operated by
several other carriers, including GTE, US West, Ameritech, BellSouth, Centennial
Cellular  Corp.,  Southwestern  Bell,  AT&T  Wireless  Communications,  Vanguard
Cellular  Systems and others.  Additionally, U.S. Cellular  has implemented four
Signal Transfer Points which  have allowed it  to interconnect efficiently  with
network providers such as Illuminet and the North American Cellular Network.
 
    During  1997, U.S. Cellular intends to  extend the network for its customers
through interconnection with additional system  operators for call delivery  and
hand-off.  This expanded network  will increase the area  in which customers can
automatically receive incoming calls,  and should also  reduce the incidence  of
"tumbling" electronic serial number fraud due to the pre-call validation feature
of  networked systems. In  addition, the extension of  these networks will allow
for the termination of wireless-to-wireless  traffic without the inherent  costs
that  are  otherwise incurred  if this  traffic is  routed through  the landline
network.
 
    U.S. Cellular  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.
 
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. In late 1996,  U.S. Cellular implemented its
new site on the WorldWideWeb to support its marketing efforts and to be a future
distribution channel.  These  U.S.  Cellular-owned  and  managed  locations  are
designed  to  market cellular  service  to the  consumer  segment in  a familiar
setting.
 
    U.S. Cellular manages each cluster of markets from an administrative  office
with   a  local  staff,  which   typically  includes  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 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
 
                                                                              11
<PAGE>
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
220  stand-alone retail stores by the end of 1996. These U.S. Cellular-owned and
operated businesses  utilize  rental  facilities  in  high-traffic  areas.  U.S.
Cellular  has implemented a uniform appearance  of 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 1996, U.S. Cellular further expanded
its  retail presence by opening smaller retail kiosks within larger merchandiser
and grocery stores.  At December  31, 1996, U.S.  Cellular had  opened over  150
"stores within a store" in Wal-Mart and Kroger locations.
 
    In  addition  to  its own  retail  centers, U.S.  Cellular  actively pursues
national retail accounts, as agents for U.S. Cellular, which yield new  customer
additions  in  multiple markets.  Agreements have  been  entered into  with such
national distributors  as  Chrysler  Corporation, Ford  Motor  Company,  General
Motors,  MCI, Radio Shack, Best Buy and Sears,  Roebuck & Co. 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 uses a  variety of direct  mail, billboard, radio,  television
and  newspaper  advertising to  stimulate interest  by prospective  customers in
purchasing  its  cellular  service  and  to  establish  familiarity  with   U.S.
Cellular's  name.  Advertising  is  directed  at  gaining  customers,  improving
customers' awareness of  the United States  Cellular 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  to
enhance  public awareness  of U.S.  Cellular, such  as providing  telephones and
service for public events and emergency uses.
 
CUSTOMERS AND SYSTEM USAGE
 
    Cellular customers come  from a  wide range of  occupations. They  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 security  purposes. Although  many 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 systems used  their cellular systems
approximately 107 minutes per  unit each month and  generated retail revenue  of
approximately  $43 per  month during  1996, compared to  95 minutes  and $44 per
month in 1995. Revenue  generated by roamers, 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  $66 during 1996.  Average
monthly  service  revenue per  customer unit  decreased approximately  8% during
1996. This decrease  is related to  the industry-wide trend  of newer  customers
tending  to use fewer minutes during peak  business hours, which has reduced the
average local  retail  revenue per  minute,  and to  declining  contribution  of
inbound  roaming revenue per customer. U.S.  Cellular believes that its customer
base is growing faster than that of the cellular industry as a whole, which  has
a  dilutive  effect  on  inbound roaming  revenue  per  customer.  U.S. Cellular
anticipates that average monthly service revenue per customer unit will continue
to decline  as  its  distribution  channels  provide  additional  customers  who
generate lower revenue per local minute of use and as roaming revenues grow more
slowly.  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 several years.
 
12
<PAGE>
    In addition to revenue from local retail customers, U.S. Cellular  generates
revenue  from  roaming customers  and  other services.  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  market area.  U.S.  Cellular has  entered into
"roaming agreements" with operators of other cellular systems covering virtually
all systems in the  United States and Canada.  These agreements offer  customers
the   opportunity  to  roam  in   these  systems.  These  reciprocal  agreements
automatically pre-register the customers of U.S. Cellular's systems in the other
carriers' systems.  Also, a  customer of  a participating  system roaming  (i.e.
traveling) in a U.S. Cellular market where this arrangement is in effect is able
to make and receive calls on U.S. Cellular's system. 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.

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 hand-held  portable cellular telephones.  Features offered  in
some of the cellular telephones include hands-free calling, repeat dialing, horn
alert and others.
 
    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.
 
    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. In 1996, the Company developed and introduced its new consumer line of
products under  the  CarryPhone brand.  These  products include  a)  Express,  a
pre-packaged   phone  plus  price  plan  aimed  at  the  convenience  buyer;  b)
TalkTracker, a  cellular phone  with usage  prepaid;  and c)  Home and  Away,  a
combination  cordless and  cellular phone in  a single  package. 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.
 
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 the Company. The  construction,
operation and transfer of cellular systems in the United States are regulated to
varying
 
14
<PAGE>
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 and makes regulation unnecessary.  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.
 
    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. U.S. Cellular is  currently engaged in  this
registration  process.  All  new  towers  must  be  registered  at  the  time of
construction  and  existing   towers  are  being   registered  on  a   staggered
state-by-state  basis,  to  be  concluded  in May  1998.  The  FCC  is currently
considering whether  to take  action to  pre-empt moratoria  imposed by  certain
localities  on the construction of wireless  towers. U.S. Cellular has supported
such FCC action.
 
    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.
U.S. Cellular's Tulsa  and Knoxville  licenses were  renewed in  1995, and  U.S.
Cellular's  Des Moines, Iowa;  Peoria, Illinois; and  Roanoke, Virginia licenses
were renewed  in 1996.  U.S. Cellular's  next renewal  applications for  several
markets are due to be filed in 1997.
 
    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
 
                                                                              15
<PAGE>
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. U.S. Cellular's strategy with respect to system construction in  its
markets  has been and will be 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 would  enable cellular systems to determine
the precise location of the person making the emergency call. 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, and will require cellular  systems to improve their ability  to
locate wireless 911 callers over a five-year period.
 
    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 the subscribers involved have  no pre-existing service relationship  with
that  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
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, at  the same  location, 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 have  implementation deadlines  by  the end  of 1998.
Broadband PCS,  cellular  and  certain  other  wireless  providers  have  phased
implementation deadlines in 1998 and 1999.
 
    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. The U.S. Court of
Appeals for the Eighth  Circuit has stayed the  effect of the rules  prescribing
interim  rates because it has  held that the 1996  Act requires that rate issues
are to be decided by the  states. However, the FCC's rules requiring  reciprocal
and  symmetrical compensation  remain in  effect. If  the U.S.  Court of Appeals
sustains its earlier ruling, interconnection rate issues will be decided by  the
states.  Whether the issue is  decided by the states  or the federal government,
cellular carriers 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 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-
 
16
<PAGE>
state Joint  Board.  Much of  this  implementation is  proceeding  in  numerous,
concurrent proceedings with aggressive deadlines. The Company cannot predict the
full   extent,   nature   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
tele-communications  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 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, it retains limited authority  to
regulate certain competitive practices in rural telephone company service areas.
 
    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. The FCC is now considering how to implement 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. It is expected that the obligation to make some
kind of payments to support universal service will be expanded to include  other
telecommunications  service providers,  including cellular  carriers. It  is not
known how those payments  may be calculated  or what revenue  base may be  used.
However,  it  is also  possible that  cellular carriers  may become  eligible to
receive universal service  support payments in  certain circumstances under  the
new system.
 
    The  FCC has also  allocated a total  of 140 megahertz  ("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.
 
    The FCC licensed the first two 30  MHz MTA frequency blocks in 1995 and  the
30  MHz block  which is reserved  for small  business entities in  1996, and has
announced the winning bidders in  the D, E and F  Block auctions in 1997.  TDS's
subsidiary,  Aerial Communications, Inc. ("Aerial"),  was licensed in eight MTAs
for 30 MHz blocks but has sold its licenses for the Guam and Alaska MTAs. It  is
now  constructing  PCS  systems  in  the  other  six  MTAs.  See  "Broadband PCS
Operations."
 
    In compliance  with FCC  restrictions on  common ownership  of cellular  and
broadband  PCS interests in overlapping market areas, U.S. Cellular entered into
a series of arrangements for the divestiture or restructuring of certain of  its
cellular  interests  in  market areas  where  Aerial was  awarded  broadband PCS
licenses. A  number of  these  proposed arrangements  required FCC  approval  of
assignment or transfer of control applications before they could be consummated.
All  of  these  applications  have  been  approved  by  the  FCC  and  have been
consummated. U.S. Cellular believes that it has taken reasonable steps to comply
with the FCC's cross-interest policies.
 
    PCS technology  is  currently  under  development and  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
 
                                                                              17
<PAGE>
services   and  will  result  in  increased  competition  with  U.S.  Cellular's
operations. The ability of these future  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.
 
    Media  reports have suggested that  certain radio frequency ("RF") emissions
from portable cellular telephones might be  linked to cancer. U.S. Cellular  has
reviewed  relevant scientific information and, based on such information, is not
aware of any credible evidence linking the usage of portable cellular telephones
with cancer. In 1996 the FCC announced rules, now scheduled to go into effect in
September 1997, dealing, INTER ALIA, with  RF emissions from cellular towers  of
less  than 10 meters in  height and cellular telephones.  It is anticipated that
U.S. Cellular will be able to comply  with RF tower emission standards and  U.S.
Cellular  believes that the  cellular telephones it  currently sells comply with
the standards.
 
    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. 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.
 
    U.S.  Cellular and  its subsidiaries have  been and intend  to remain active
participants in proceedings before the FCC and, through its membership in  state
associations   of  wireless  providers,  before  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, among other  technologies, conventional mobile
telephone and SMR systems, both of which  are able to connect with the  landline
telephone  network. U.S.  Cellular believes  that conventional  mobile telephone
systems and conventional SMR systems are competitively disadvantaged because  of
technological  limitations  on  the  capacity  of  such  systems.  The  FCC  has
previously given approval, through  waivers of its rules,  to ESMR, an  enhanced
SMR  system.  ESMR systems  may  have cells  and  frequency reuse  like cellular
thereby potentially eliminating any current technological limitation. The  first
 
18
<PAGE>
ESMR  systems were implemented in 1993 in  Los Angeles and are being implemented
in many other  cities across the  United States. ESMR  providers have  initiated
service in several areas where U.S. Cellular operates cellular systems. Although
less  directly a  substitute for  cellular service,  wireless data  services and
one-way paging  service (and  in the  future, two-way  paging services)  may  be
adequate for those who do not need full two-way voice service.
 
    PCS  providers have initiated  service in several  markets across the United
States, including  markets where  U.S. Cellular  has operations.  PCS  providers
offer  digital,  wireless communications  services  to their  customers. Similar
technological advances or regulatory  changes in the  future may make  available
other  alternatives to cellular service,  thereby creating additional sources of
competition. U.S. Cellular expects PCS operators to continue deployments of  PCS
across  all of the  U.S. Cellular markets over  the next one  or two years. U.S.
Cellular anticipates that PCS competitors will build out the larger metropolitan
areas before  the mid-sized  metropolitan and  rural areas  where U.S.  Cellular
operates.  As  a result,  the  effects of  PCS  competition may  not  reach U.S.
Cellular's markets as quickly as they may in other cellular operators' markets.
 
    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
 
    The Company's telephone operations are conducted through TDS Telecom and 105
telephone  subsidiaries. These  telephone companies,  ranging in  size from less
than 500 to  more than 40,000  access lines,  serve 484,500 access  lines in  28
states.
 
    TDS  Telecom provides modern, high-quality local and long-distance telephone
service.  Local  service  is  provided  by  TDS  Telecom's  operating  telephone
subsidiaries. Long-distance or toll service is provided through connections with
long-distance   carriers,  primarily  AT&T  and  the  Bell  Operating  Companies
("BOCs").
 
    Future growth in  telephone operations is  expected to be  derived from  the
acquisition  of additional telephone companies, from providing service to new or
presently unserved establishments, from business  expansion in the areas  served
by  TDS Telecom, from upgrading existing  customers to higher grades of service,
from increased usage of the network through both local and long-distance calling
and from providing additional services made possible by advances in technology.

TELEPHONE ACQUISITIONS
 
    TDS  continually  reviews  attractive  opportunities  to  acquire  operating
telephone  companies.  Since  January 1,  1992,  TDS has  acquired  22 telephone
companies serving a total of 90,400 access lines for an aggregate  consideration
totaling  $297.1 million. The  consideration consisted of  $59.5 million in cash
and notes,  155,000  Preferred Shares  and  5.2  million Common  Shares  of  the
Company. TDS also sold one telephone company serving 1,100 access lines in 1995.
 
    The  Company  continually  evaluates  acquisition  opportunities.  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.  While  management  believes  that  it  will  be
successful in making additional acquisitions, there can be no assurance that the
Company will be able to negotiate additional acquisitions on terms acceptable to
it or that regulatory approvals, where required, will be received.
 
    The  Company maintains shelf registration of its Common Shares and Preferred
Shares under the Securities Act of 1933 for issuance specifically in  connection
with acquisitions.
 
    It  is  the Company's  policy to  preserve, insofar  as possible,  the local
management of  each telephone  company  it acquires.  The Company  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  the  following areas:
finance, accounting and treasury services; marketing; customer service; traffic;
engineering and construction; customer billing; rate administration; credit  and
collection; and the development of administrative and procedural practices.
 
CONSTRUCTION AND DEVELOPMENT PROGRAM
 
    In  1996, and continuing in 1997, TDS  Telecom has expanded and upgraded its
service  providing  network  in  accordance  with  its  first-to-market  service
provisioning strategy. Utilizing state-of-the-art technologies such as Signaling
System  7  ("SS7"),  Advance  Calling Services  ("ACS"),  and  fiber-fed Digital
Serving Areas  ("DSA") to  condition  the network  for the  Integrated  Services
Digital Network ("ISDN"), TDS Telecom will bring cutting edge telecommunications
services to its predominantly rural markets. TDS Telecom intends to utilize this
world-class  network as a competitive advantage to protect and grow its customer
base in the  increasingly competitive telecommunications  industry. TDS  Telecom
made   significant  progress  in  1996  in  network  modernization  through  the
deployment of 425 miles of fiber optic  cable and 207 DSAs. TDS Telecom  further
embraced  its strategic alliance with  Lucent Technologies and Siemens Stromberg
Carlson by continuing its program of upgrading switching platforms. In 1996,  35
new  switching systems,  including eight  hosts, were  installed representing an
additional 50,900 lines
 
20
<PAGE>
and making  available an  additional 50,900  lines  of ISDN,  SS7 and  ACS.  TDS
Telecom  plans to  install 530  additional miles  of fiber  optic cable  and 214
additional DSAs in  1997. TDS  Telecom's 1997 switching  platform upgrade  plans
include  45  additional  switching  systems  including  eight  additional  hosts
representing 43,900  lines, to  bring the  cumulative total  Lucent and  Siemens
installed  lines to 276,000. As a result, TDS Telecom will make available to its
customers 45,300 additional lines of ISDN, SS7 and ACS. By the end of 1997,  TDS
Telecom  projects having 289,338  ISDN, 344,686 SS7,  and 320,183 ACS cumulative
equipped lines  representing 57%,  68% and  63%, respectively,  of all  equipped
lines.
 
    In  1996, TDS Telecom continued its  efforts to reduce costs while improving
its customer responsiveness  by further deployment  of its Transmission  Control
Protocol/Internet Protocol ("TCP/IP") data network to an additional 55 operating
locations.  The TCP/IP network is utilized  by TDS Telecom's centralized network
management center  ("NEMAC") to  monitor the  switching network  for errors  and
provide  corrective action  even before the  customer realizes that  a fault has
occurred. The  TCP/IP data  network also  provides transport  for TDS  Telecom's
support  and  service  centers,  allowing  for  increased  coverage  of customer
inquiries and their related customer care  systems. Rollout of the data  network
to additional operating locations is planned for 1997.
 
    TDS  Telecom  supplemented  its  revenue  in  1996  with  the  deployment of
additional Internet nodes through its wholly owned Internet subsidiary,  TDSNET.
TDSNET  deployed 61 additional operating nodes in  1996 and expects to deploy at
least 30 more nodes in 1997. In 1996, voicemail deployment continued to 16  more
serving  areas. TDS Telecom will continue to  enhance its voice mail revenues in
1997 through the installation of an additional seven systems.
 
    TDS Telecom's total 1997 capital budget is $130.0 million compared to actual
capital expenditures  of $144.4  million in  1996 and  $104.4 million  in  1995.
Financing  for  the  1997  capital  additions  will  be  primarily  provided  by
internally generated funds and supplemented by federal long-term financing.
 
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 make hardship loans at a 5% interest 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 (6.42% for its fiscal year ended September 30, 1996), 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 (6.72%
for a 35-year note at December 31, 1996).
 
    Substantially all of TDS Telecom's telephone plant is pledged or is  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.  Of  the  $301.6 million  of  underlying  retained
earnings  of telephone  subsidiaries at  December 31,  1996, $212.0  million was
available for the payment of dividends on the subsidiaries' common stock.
 
    At December  31,  1996,  TDS Telecom's  operating  telephone  companies  had
unadvanced loan commitments under the RUS, RTB and FFB loan programs aggregating
approximately  $129.8 million,  at a  weighted average  annual interest  rate of
6.15%, to finance  specific construction  activities in 1997  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.
 
ACCESS REVENUES
 
    TDS  Telecom's operating telephone subsidiaries  receive access revenue from
interstate  and  intrastate   long-  distance  carriers   as  compensation   for
originating and terminating their traffic. The interstate
 
                                                                              21
<PAGE>
and intrastate access rates charged include the cost of providing service plus a
fair  rate  of return.  Access  revenues account  for  approximately 55%  of the
revenue generated by TDS Telecom's local exchange carrier ("LEC") subsidiaries.
 
    TDS Telecom  will file  an interstate  access  rate tariff  for one  of  its
operating  subsidiaries in  1997. However  TDS Telecom  concurs in  the National
Exchange  Carrier  Association  ("NECA")  interstate  common  line  and  traffic
sensitive  tariffs for  the remainder of  its LEC  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 operates subject to FCC rules and oversight.
 
    The FCC  regulates  interstate toll  rates  and other  matters  relating  to
interstate telephone service. On December 23, 1996, the FCC released a notice of
proposed rulemaking regarding interstate access revenues. In the notice, the FCC
stated  its intention to reform the  existing interstate access charge rules and
policies and sought comment  from interested parties. The  FCC did not  indicate
what  changes it will propose; however, final rules are expected by May 8, 1997.
The outcome of this and other  rulemaking proceedings may affect the source  and
nature  of  the  operating  companies' recovery  of  costs  from  the interstate
jurisdiction. In the past, the FCC  has generally adopted transition rules  when
changing cost recovery mechanisms to prevent abrupt rate and revenue changes.
 
    The  1996  Act  provides  for reciprocal  compensation  for  parties  of any
interconnection  arrangement.  The  FCC  issued  a  1996  order  governing   the
compensation  arrangements between LECs and wireless providers. LECs must charge
wireless carriers cost-based rates and must  now pay access charges to  wireless
carriers  that  terminate  calls from  LEC  customers. Since  this  order raises
interconnection costs,  the  operating companies  may  adjust their  charges  to
recover such increased costs.
 
    The  FCC  has  also  stated  its intention  to  initiate  review  of current
procedures for separating incumbent  LECs' service costs  between the state  and
federal jurisdictions. To the extent that cost allocations have been used in the
past  to limit the costs a LEC must recover in local or intrastate access rates,
the proceeding may seek to  shift costs to the states.  To the extent that  such
support  is  not  made  up  in  the  new  federal  and  state  universal service
mechanisms, TDS Telecom  may seek  rate increases  to offset  any reductions  in
interstate revenues.
 
    Where applicable and subject to state regulatory approval, TDS Telecom's LEC
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 LECs,  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.
The impact  of the  1996 Act  is likely  to accelerate  the pace  of  regulatory
re-evaluation  at both the  state and federal  level. To the  extent that state-
ordered  access  charge  revisions  reduce   revenues,  TDS  Telecom  may   seek
adjustments  in other rates. Given the  many regulatory issues still unresolved,
TDS Telecom  cannot predict  the cumulative  nature or  extent of  impacts  from
regulatory reform.
 
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  LEC  subsidiaries provide
telephone service in  rural areas  and virtually all  of them  offer service  to
low-income  customers. To control the cost  of universal service, the FCC capped
and indexed the universal service fund through 1996.
 
    The 1996  Act codified  universal service;  set forth  clear principles  for
ensuring  affordable access to modern  telephone service nationwide; established
discounts  for  rural  schools,  libraries  and  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.
The  joint board convened and released its recommendation to the FCC on November
8, 1996. The joint  board and FCC are  considering controlling and reducing  the
total amount of universal service support. The joint board has proposed not only
using forward-looking proxy costs to measure high cost support, but also using a
nationwide
 
22
<PAGE>
average  revenues-per-line  benchmark that  has  the potential  to underestimate
rural LECs' high costs and thus limit their high cost support. The FCC opened  a
comment  cycle  on the  joint  board recommendation  and  TDS Telecom  has filed
comments and reply comments.
 
    One major  principle of  the 1996  Act is  that support  shall be  specific,
predictable  and sufficient. In its comments to  the FCC, TDS Telecom stated its
position that rural  telephone companies,  as defined  in the  1996 Act,  should
continue  to  base  their  costs  on  embedded  (historical)  rather  than proxy
(forward-looking) costs  proposed by  the joint  board. This  would ensure  that
support  is predictable and  sufficient. Because the 1996  Act also attempted to
eliminate implicit subsidies, TDS Telecom also suggested in its filing with  the
FCC  that the cost to support universal service  should be added to the end user
bills generated by all telecommunications  carriers. Such an explicit  surcharge
would  ensure adequate support and  eliminate the need for  LECs to pursue local
service rate increases for the potential  changes. The FCC is expected to  issue
an Order on universal service by May 8, 1997.
 
    The  final rules to  implement the universal service  provisions of the 1996
Act could  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  decrease,TDS Telecom's  LEC subsidiaries  may
pursue local service rate increases to recover the difference.
 
    Telephone company acquisition and investment decisions assume the ability to
recover  the cost and a  reasonable rate of return  though local service, access
and support  revenues.  Significant changes  in  the universal  service  funding
system  might affect the Company's acquisition strategy. TDS Telecom is pursuing
a strategy of network modernization  to maintain a strong competitive  position.
The  speed of  such network  modernization may  depend on  favorable support and
access policies on the federal and state levels.
 
REGULATION
 
    TDS Telecom's LEC  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, is subject to state commission  approval. 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,  accounting
and related matters. 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,  it
retains  limited authority  to regulate  certain competitive  practices in rural
telephone company service areas.
 
    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.
 
    Unless  exempted, or granted suspension or modification, incumbent LECs 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 provide only those elements they choose to provide; (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.
 
    As defined in the 1996 Act, TDS Telecom's LEC subsidiaries qualify as  rural
telephone  companies. Therefore, they enjoy an  exemption from the incumbent LEC
requirements until they receive a bonafide
 
                                                                              23
<PAGE>
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 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.
 
    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
ensure that any telecommunications reform measures treat rural areas fairly. The
ongoing  changes in public  policy and introduction  of competition might affect
the earnings  of the  operating subsidiaries  and  TDS Telecom  is not  able  to
predict the impact.
 
    While  the majority of TDS Telecom's LEC subsidiaries continue to operate in
a rate-of-return  environment, a  number of  state commissions  are  proactively
negotiating  alternative regulation plans with  LECs. Price regulation, the most
common form of alternative regulation, focuses on the price of telecommunication
services. TDS  Telecom's  LEC subsidiaries  in  both Alabama  and  Michigan  are
currently operating in a price-regulated environment, whereby the commissions in
those  states are no longer reviewing earnings. For several years, the RBOCs and
some of the nation's larger  LECs have operated under  an FCC "price cap"  plan,
where earnings can only be increased through productivity improvements. The LECs
determine the amount of productivity gains above an allowed return and then must
share the excess gains with their customers.
 
    For  1997, TDS Telecom's  telephone subsidiaries have  neither elected price
caps nor the alternative FCC plan, which was designed for smaller LECs. Instead,
the operating subsidiaries will continue to abide by traditional  rate-of-return
regulation  for  interstate  purposes.  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 is  currently considering whether to  initiate a proceeding  to
lower the allowed rate-of-return for rate-of-return LECs.
 
    NECA  filed  a Petition  for Rulemaking  with the  FCC, which  proposes rule
revisions to allow incentive settlement options  within the NECA pools. The  FCC
has  not acted on this petition yet. The settlement options allow LECs to remain
in the  NECA pools  and  still enjoy  incentives  previously available  only  to
non-NECA  participants. Management continues to evaluate opportunities under all
forms of regulation.
 
    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 should not be higher in rural areas than in urban areas. The
statute is intended  to ensure  affordable long  distance services  even in  TDS
Telecom's most remote exchanges.
 
COMPETITION
 
    The  1996  Act  will  help  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  applies  expanded   interconnection  and   other
requirements   to  local  exchange  telephone   companies  for  the  purpose  of
stimulating competition.  The  Act establishes  a  framework for  local  service
competition  and  it  establishes  different standards  for  different  types of
telecommunications carriers. The Act  defines rural telephone companies  ("RTC")
and  provides them with an exemption from certain incumbent LEC obligations. All
TDS Telecom LECs  meet the RTC  definition and  fall under the  exemption. At  a
minimum,  this likely will  delay certain forms of  competition occurring in our
LECs while additional regulatory issues are resolved.

<PAGE>
    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.  Accordingly,  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.  To
face  this  increasing  competition, TDS  Telecom  has  strategically positioned
itself to  provide  customer  intimacy  and to  provide  complete  solutions  to
customers' telecommunication needs.
 
    To  position TDS Telecom as a customer-intimate organization, TDS Telecom is
dedicating resources to establishing a Virtual Business Office ("VBO"). The  VBO
is an environment that is technically equipped to enable multiple local business
offices to perform customer contact functions as if they were a "virtual" office
in  the eyes of the  customer. VBO is TDS  Telecom's solution to connect offices
together to better use resources  and preserve local presence. Through  extended
availability that coincides with customers' schedules and expectations, VBO will
help  provide greater  market coverage  and customer  service on  the customer's
terms. It will  also enable the  business office teams  to deliver  high-quality
service  to  the customer  through more  efficient call  answering capabilities,
provide continued focused local service to walk-in customers, and leverage voice
and customer service application technology.
 
    TDS Telecom is  providing the  operating telephone companies  with the  most
advanced central office switching equipment possible in order to offer customers
up-to-date  technology such as ISDN,  Advanced Calling Services, High-Speed Data
access and  Internet  access.  TDS  Telecom  sees  expanded  competition  as  an
opportunity  to  provide a  broader range  of  services to  a greater  number of
potential customers. TDS Telecom plans to provide its customers bundled  service
offerings  and become a "one stop shop" for all its customers telecommunications
needs. In 1996,TDS Telecom  entered into new  competitive markets with  products
like  LAN and data structured wiring  (connecting computers in multiple customer
locations), and resale of Direct Broadcast Satellite. TDS Telecom also  expanded
its  Internet access  service through its  subsidiary, TDSNET.  TDS Telecom will
continue to seek additional attractive  opportunities in competitive markets  in
1997.
 
                            BROADBAND PCS OPERATIONS
 
    The   Company's  broadband  PCS  operations  are  conducted  through  Aerial
Communications, Inc. and  subsidiaries. Aerial is  currently developing its  PCS
licenses   covering  the  MTAs  of  Minneapolis,  Tampa-St.  Petersburg-Orlando,
Houston, Pittsburgh, Kansas City and Columbus. Aerial has commenced  development
of  a  marketing program,  intends to  launch commercial  services in  its first
market in March 1997,  and expects to complete  initial construction of its  PCS
networks within twelve months of launch of commercial service.
 
THE WIRELESS TELECOMMUNICATIONS INDUSTRY
 
    PCS  is the term  used to describe  the wireless telecommunications services
that will be offered by those  companies that acquired or will acquire  licenses
for  radio spectrum (frequency range 1850-1990 MHz)  in the FCC auctions and are
the  newest  entrants  in  the  wireless  telecommunications  market.  PCS  will
initially  compete directly with existing  cellular telephone, paging and mobile
radio services. PCS will also include features which have not traditionally been
offered by cellular providers, such as: (i) the provision of all services to one
untethered, mobile number; (ii) lower-priced  service options; and (iii) in  the
near  future, medium-speed  data transmissions  to and  from portable computers,
advanced paging  services and  facsimile services.  Aerial believes  that  these
enhanced  features will contribute to the acceleration of growth in the wireless
telecommunications market. Aerial believes that PCS providers will be the  first
wireless  direct competitors to  cellular providers and the  first to offer mass
market all-digital mobile networks. In addition, 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.
 
    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
 
                                                                              25
<PAGE>
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
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.
 
    Global System for Mobile Communications ("GSM"), Aerial's technology choice,
is  not directly  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.
Dual-mode  handsets are  expected to be  available in late  1997. Because analog
cellular service is available nationwide, Aerial expects the PCS customers  will
be able to roam into many service areas by analog cellular providers.
 
    To  date,  in North  America, nearly  20  PCS companies  have chosen  or are
expected to choose GSM. With the completion of the U.S. broadband PCS  auctions,
license  areas  of  GSM committed  operators  now  total more  than  260 million
population equivalents  (representing  98.3%  of the  U.S.  population).  Aerial
anticipates that its customers will be able to roam throughout the United States
and  Canada,  either  on other  GSM-based  PCS  networks or  by  using dual-mode
handsets that also can be used on existing cellular networks.
 
    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.
 
PRODUCTS AND SERVICES
 
    Aerial's  fundamental customer proposition will  be an affordable, reliable,
high-quality  mobile  voice  communications  service.  At  the  commencement  of
commercial  service, Aerial intends to offer 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 is competitive with that of current
cellular operators.  Aerial  will  also provide  roaming  capabilities,  through
agreements with other GSM operators and cellular operators.
 
26
<PAGE>
    Aerial will provide several distinct services and features, certain of which
are currently available only on PCS networks. These include:
 
    THE SMART CARD.  GSM technology employs a credit-card sized Smart Card which
contains  a microchip containing detailed information about a customer's service
profile. The  Smart Card  will allow  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 will
provide easy-to-use, interactive menu-driven  phones that will enable  customers
to  utilize  the  features  available  in a  GSM  network.  These  handsets will
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 will  provide greater  security  from
eavesdropping  and cloning than existing  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.
 
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  will be  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  will  emphasize  the  value  of Aerial's
high-quality, innovative services and will be supported by heavily promoting the
Aerial brand name. This will be supported by a substantial advertising program.
 
    Aerial plans to offer 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 will  utilize traditional  sales channels
which include  mass merchandisers  and retail  outlets, company  retail  stores,
sales  agents and a direct sales force. 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, neighborhood sales
and on-line sales.
 
AERIAL'S PCS MARKETS
 
    The  PCS   markets   cover   large   areas   with   attractive   demographic
characteristics   including  growing  populations,  high  population  densities,
favorable commuting  patterns,  high  median  household  incomes  and  favorable
business  climates. Aerial believes the geographic  diversity of the PCS markets
mitigates adverse consequences which may result from an economic slowdown in one
particular region.
 
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.
 
                                                                              27
<PAGE>
    Aerial   anticipates  that  market  prices  for  two-way  wireless  services
generally will decline in  the future based  upon 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.
 
    Aerial  will compete 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). Each  of these PCS
licensees is designing and constructing  its respective networks. PCS  PrimeCo's
networks  are commercially operational in Houston and Tampa. Sprint Spectrum has
launched commercial  service in  Pittsburgh.  The FCC  has awarded  the  initial
licenses for the Block C spectrum and has recently announced the winning bidders
for  the D, E and F Blocks. Aerial also expects that existing cellular providers
in the PCS markets, most of which have an infrastructure in place and have  been
operational  for  a number  of  years, will  upgrade  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.,  U  S  WEST
NewVector Group, Inc., Bell Atlantic-NYNEX Mobile and Ameritech Cellular.
 
    Aerial  also expects to compete  with other communications technologies that
now exist, such as  paging, ESMR and global  satellite networks, and expects  to
compete with cellular and PCS resellers. 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.  In addition, Aerial may face
competition from technologies that may be introduced in the future.
 
    All of such competition is expected to be 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.
 
    Handsets   used  for  GSM-based  PCS  networks  will  not  be  automatically
compatible with  cellular  systems, and  vice  versa. Aerial  expects  dual-mode
handsets  to be available in late 1997,  which will permit its customers to roam
by using the existing  cellular wireless network in  other markets. Until  then,
this  lack of  interoperability may impede  Aerial's ability  to attract current
cellular customers or potential new wireless communication customers that desire
the ability to access different service providers in the same market.
 
REGULATION
 
    REGULATORY ENVIRONMENT.   The  FCC  regulates the  licensing,  construction,
operation  and acquisition  of wireless  telecommunications systems  in the U.S.
pursuant to  the Communications  Act, 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 forfeitures for
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
 
28
<PAGE>
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  unnecessary. The FCC promulgated and
continues to  promulgate regulations  governing  construction and  operation  of
wireless  providers,  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  BTA in every
block, for a  total of  more than  2,000 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.  The FCC has awarded  the initial licenses for  the C Block spectrum
and has recently announced the winning bidders for the D, E and F Blocks.
 
    An appeal  has been  taken to  the  FCC from  the Bureau  order by  a  party
alleging  that  some of  the authorizations  were granted  to parties  which had
engaged in collusion  in the competitive  bidding process. That  party has  also
sought  review of the denial  of its motion for  a stay of the  grant of A and B
Block authorizations. No allegation of collusion was made against TDS or Aerial.
Aerial would defend vigorously any challenges to the authorizations it has  been
granted.
 
    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.
 
    In compliance  with FCC  restrictions on  common ownership  of cellular  and
broadband  PCS interests  in overlapping  market areas,  United States Cellular,
another subsidiary  of  TDS, entered  into  a  series of  arrangements  for  the
divestiture  or restructuring  of certain  of its  cellular interests  in market
areas where  Aerial  was awarded  broadband  PCS  licenses. A  number  of  these
proposed arrangements required FCC approval of assignment or transfer of control
applications  before  they could  be consummated.  These applications  have been
approved by the FCC and have been consummated.
 
    The grants of licenses to Aerial are also 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 license  grant and
coverage of two-thirds of that population within ten years. A significant factor
affecting the schedule and cost of  Aerial's network implementation will be  the
relocation  of existing private  microwave facilities which  operate on the same
frequencies to be used  for Aerial's broadband PCS  operations. Under the  FCC's
policies,  if  Aerial  decides  that any  existing  microwave  facility  must be
relocated, it is required to provide substitute facilities at its own expense so
that the companies using these existing  facilities may continue to have  access
to  the  same  or  equivalent  communications  capabilities.  The  FCC concluded
proceedings in 1996  clarifying and  changing its  requirements for  permissible
relocation  costs,  adopting  incentives  to  encourage  reliance  on  voluntary
relocation agreements and requiring  the sharing of  relocation costs where  the
relocation  of  private  microwave facilities  benefits  multiple  broadband PCS
licenses.
 
                                                                              29
<PAGE>
    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"
performance, 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.  The FCC adopted  certain significant decisions during 1996.
In one decision,  the FCC required  that all licensees  register and obtain  FCC
registration  numbers for  all of their  antenna towers which  require prior FAA
clearance. The FCC also amended its environmental protection rules to adopt  new
guidelines  and  procedures  for  evaluating  the  environmental  effects  of RF
emissions.
 
    The FCC has  also imposed new  "enhanced 911" regulations  in broadband  PCS
systems  to determine  the precise location  of the person  making the emergency
call. The new rules  require broadband PCS providers  to work with local  public
safety  officials  to  process  911  calls,  including  those  made  from mobile
telephones not registered with  the broadband PCS provider,  and to meet  phased
deadlines for implementing these capabilities.
 
    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 the subscribers involved have  no pre-existing service relationship  with
that  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
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, at  the same  location, 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  have
implementation deadlines by the end of 1998. Broadband PCS, cellular and certain
other wireless providers have phased implementation deadlines in 1998 and 1999.
 
    The  FCC is also proceeding 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 is proceeding in numerous, concurrent proceedings with aggressive
deadlines.  Aerial cannot predict the full extent, nature 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 -- 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
 
30
<PAGE>
quality  and consumer  rights. While  a state  may not  impose requirements that
effectively function  as barriers  to  entry, it  retains limited  authority  to
regulate certain competitive practices in rural telephone company service areas.
 
    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  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
have  been taken to  the United States  Court of Appeals  for the Eighth Circuit
from these FCC orders by numerous parties alleging that the FCC has exceeded its
statutory mandate, among other matters. The Eighth Circuit Court granted a  stay
of certain rules adopted in the FCC orders pending its decision on the merits of
these appeals.
 
    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.  The FCC  has  proceedings pending  to address
recommendations made by the  Joint Board with respect  to the implementation  of
the universal service provisions of the 1996 Act, including, among other issues,
the size of the universal service fund and the assessment mechanism to determine
how much individual wireless carriers will be required to contribute.
 
    STATE  AND LOCAL REGULATION.  The scope of state 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 pre-emption  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 pre-emption  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 and local 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.

WIRELESS MESSAGING INDUSTRY
 
    Paging  is  a wireless  communications  messaging technology  which  uses an
assigned radio frequency,  licensed by  the FCC,  to contact  a paging  customer
within  a geographic service  area. Pagers are  small, lightweight, easy-to-use,
battery-operated devices  which receive  messages by  the broadcast  of a  radio
signal.  To contact a  customer, a message  is initiated by  placing a telephone
call to the customer's pager number or through computer software which enables a
computer to transmit a text message via the modem line. The message is  received
by   a   computerized  paging   switch  which   generates   a  signal   sent  to
microprocessor-controlled radio  transmitters  within the  service  area.  These
radio transmitters are connected to the paging terminal either through land-line
or  satellite links. The transmitters broadcast  a digital or analog signal that
is received by the pager and delivered as alphanumeric text, numerical  display,
tone or voice message.
 
    The  paging industry  started in 1949  when the FCC  allocated certain radio
frequencies for exclusive use in providing  one-way and two-way types of  mobile
communications  services. The industry grew slowly during its first thirty years
as the quality and reliability of  equipment was developed and the market  began
to  perceive  the  benefits of  wireless  communications. Until  the  1980s, the
industry was highly fragmented  with a large number  of small, local  operators.
During  that decade, acquisitions of many  firms by regional telephone companies
and  others   greatly  consolidated   the  industry.   Several  large   industry
acquisitions   occurred  in  the  1990s  which   has  resulted  in  the  further
consolidation of the paging industry.
 
    Manufacturers of pagers and transmission equipment have produced  innovative
technological  advances which are expected to  continue to broaden the potential
market size for paging  services and support the  industry's rapid growth  rate.
Micro circuitry, liquid crystal display technology and digital signal processing
have  all expanded the capability and capacity of paging services while reducing
equipment and airtime  costs and  equipment size. Narrowband  PCS technology  is
expected  to greatly expand the messaging  capacity of the paging infrastructure
and provide  advanced  two-way  messaging  and  data  services.  Future  service
offerings  are expected to include acknowledgment paging, which allows customers
to confirm  a message  to the  originator, as  well as  digitized voice  paging,
two-way  data conveyance to highly mobile  devices such as lap-top computers and
Personal Digital Assistants ("PDA"), and other data transfer applications.
 
    The following table summarizes  certain information about American  Paging's
operations.

COMPANY DEVELOPMENT
 
    American  Paging's business  strategy is  to promote  above industry average
growth in customers, service  revenue and operating cash  flow by providing  the
highest  quality  service through  one  of the  industry's  most technologically
advanced digital transmission systems  with a focus  on strong customer  service
and competitive pricing.
 
    SPECTRUM  DEVELOPMENT.   American Paging  owns five  regional narrowband PCS
licenses which provide coverage equivalent to that of a nationwide license. Each
of the five licenses consists of a 50 kHz outbound channel on frequency  930.625
MHz  paired  with a  12.5 kHz  return  channel on  frequency 901.80625  MHz. The
licenses will eventually  enable American Paging  to introduce two-way  wireless
messaging  communications  services  including acknowledgment  paging,  data and
telemetry services, wireless e-mail and digitized voice messaging throughout the
United States. However, commerical unavailability of the
ReFLEX25-Registered  Trademark-   protocol   and  related   infrastructure   and
subscriber  device equipment necessary  to offer these  services has resulted in
American Paging suspending development of its PCS licenses. American Paging also
intends to  continue  exploring synergies  with  affiliated companies,  such  as
United States Cellular Corporation and Aerial Communications, Inc.
 
32
<PAGE>
    American  Paging also  owns an  exclusive nationwide  Private Carrier Paging
("PCP") channel on frequency 929.3375 MHz. American Paging believes this license
will enable it to offer  competitive regional and nationwide wireless  messaging
services.  American  Paging's Minnesota,  Oklahoma,  Texas and  Washington, D.C.
systems currently utilize this frequency.
 
    The narrowband PCS licenses and the PCP license will provide American Paging
with significant spectrum capacity upon which to offer future wireless messaging
services. Significant funds will be required when American Paging proceeds  with
development  of its  narrowband PCS  licenses and PCP  license. There  can be no
assurance that American Paging will  be successful in developing these  licenses
due  to  such factors  as  the inability  to  obtain sufficient  financing  at a
reasonable cost,  availability  of  the supporting  infrastructure  and  related
subscriber  device  equipment,  competition,  regulatory  developments  or other
factors.
 
    ALLIANCES AND AFFILIATES.  American Paging  is a joint venture partner  with
Nexus  Telecommunication Systems Ltd. of  Israel ("Nexus") in American Messaging
Services, LLC  ("AMS"). AMS  was  formed to  develop multiple  applications  and
distribution  channels  worldwide  for a  patented  communications  network that
provides two-way  paging, location  and telemetry  services. In  June 1996,  AMS
constructed  a  beta-test  system  in Chicago  to  perform  radio  frequency and
infrastructure tests. The system is still being tested, while also serving as  a
demonstration  system  for prospective  customers  of a  Nexus-based technology.
American Paging has notified Nexus that it will stop funding AMS as of June  30,
1997. As a result, American Paging's interest in AMS may be diluted.
 
    American  Paging also has an agreement with  Liazon, Inc. of Toronto for the
coordinated development and use  of narrowband PCS  and conventional PCP  paging
frequencies  in North  America. Under the  terms of the  agreement, each company
will pursue its own PCS  build out plans, but will  have the added potential  to
market  North American  coverage of advanced  wireless messaging  services. In a
related action,  both the  FCC  and Industry  Canada have  provided  conditional
authority for both companies to construct and operate transmitters in previously
restricted areas.
 
APP RESTRUCTURING
 
    During  the third quarter of 1995, American Paging began restructuring three
key operating areas: sales and marketing, administration, and customer  service.
The  impact on operations from these  restructuring efforts was more severe than
originally anticipated, and results from operations were negatively impacted  in
1995  and  1996. The  changes  implemented in  1996  caused disruptions  in many
aspects of the  business, and  also resulted in  additional restructuring  costs
being  recorded during 1996. These disruptions  led to several senior management
changes including the appointment of a new President and Chief Executive Officer
and a new  Vice President-Sales, Marketing  and Field Operations  in the  second
half   of  1996.  Additionally,  American  Paging  recently  added  a  new  Vice
President-Development and Engineering and a new Vice President-Finance and Chief
Financial Officer.
 
    The  first  goal  of  the   restructuring  effort  was  to  increase   sales
productivity  through improved direct  sales efforts and  improved customer mix.
Towards  this  end,  American  Paging  increased  the  number  of  direct  sales
representatives  with the goal of increasing growth in units in service, revenue
and average monthly  service revenue  per unit ("ARPU").  During 1996,  American
Paging  increased  the number  of employees  involved in  the sales  function to
approximately 60%  of total  employees, but  improvements in  units in  service,
service  revenue  and ARPU  growth were  not achieved  due to  dislocations from
restructuring-related activities within  the sales and  customer support  areas.
American  Paging's strategy  is to organize  the department on  a market segment
basis so that the sales and marketing  employees will be better able to  address
current  customer demands, and  also be more responsive  to changes within those
market segments.
 
    The second  and third  goals  of the  restructuring  effort were  to  reduce
administrative  expense  and  improve  customer  service.  An  integral  part of
achieving these two goals was  the consolidation of 17  geographically-dispersed
customer  service and administrative units  into a centralized Customer Telecare
Center ("CTC") located  in Oklahoma  City, Oklahoma.  The CTC,  opened in  April
1996,  now handles all back office  activities including customer service, order
fulfillment, customer billing and collections, and is available 24  hours-a-day,
seven  days-a-week. The process of implementing the CTC, as well as changing the
way American  Paging  sells,  services  and supports  its  customers,  was  very
disruptive  to  operations  during  1996.  As  a  result,  restructuring-related
expenses recorded during 1996 include a
 
                                                                              33
<PAGE>
write-down  of inventory identified as obsolete upon centralization of inventory
management at  the  CTC, as  well  as  costs for  duplicate  staffing,  employee
severance,  and consulting and legal fees. In addition, during the consolidation
of customer information databases at the  CTC, it became apparent that  American
Paging's  customer management and billing system did not provide the flexibility
necessary to support its future customer growth and retention. The creation  and
successful  operation  of the  CTC is  critical  to achieving  American Paging's
objective of growth in units, service revenue and ARPU.
 
PAGING OPERATIONS
 
    American Paging provides local, statewide, regional and nationwide advanced,
one-way digital wireless  messaging communications services  to customers in  21
states and the District of Columbia through its 51 sales and service offices. It
offers  local  and  regional  paging coverage  throughout  Florida,  the Midwest
(including all or  parts of Minnesota,  Wisconsin, Missouri, Illinois,  Indiana,
and   Kentucky),  the  Mid-Atlantic   (including  all  or   parts  of  Maryland,
Pennsylvania, Virginia,  and Washington,  D.C.), and  in portions  of  Oklahoma,
Texas, Arizona and Utah. One-way paging services are also offered in portions of
Ohio,   Iowa  and   Southern  California   through  various  transmitter-sharing
agreements with nonaffiliated service providers. Nationwide one-way and  two-way
paging   services  are   offered  through   American  Paging's   alliances  with
nonaffiliated service providers.
 
    Generally, a paging system  consists of a  control center, transmitters  and
dedicated  links (wire,  fiber optic, radio,  or satellite)  between the control
center and the  transmitters and the  pagers themselves. The  control center  is
interconnected  with the public switched telephone network ("PSTN") and receives
messages from landline telephones. Messages  received at the control center  are
matched  to each pager's unique telephone number, or "cap code," translated into
digital  signals  and  forwarded  over  dedicated  links  to  transmitters  that
broadcast  the message  over a  specified frequency. If  the pager  to which the
message is directed is in the  transmitter coverage area, it will recognize  its
"cap code" and indicate to its wearer that it has received a page.
 
    American  Paging  currently provides  four  types of  pagers  in all  of its
markets:  alphanumeric   text  display,   numeric  display,   tone  and   voice.
Alphanumeric  text  display  service  allows customers  to  receive,  store, and
display full text  messages, consisting of  both numbers and  letters up to  240
characters  long,  which  are sent  from  either  a data  entry  device, message
dispatch operator or via  computer modem through  messaging software. A  numeric
display  pager permits a  caller to transmit  to the customer  a numeric message
that may  consist of  a telephone  number, an  account number  or coded  numeric
information.  It has  the memory  capability to  store several  numeric messages
which can be recalled by  the customer when desired.  A tone pager notifies  the
customer  that  a  message  has  been  received  by  emitting  an  audible beep,
displaying a flashing  light or  vibrating. In the  case of  voice service,  the
notification is followed by a brief voice message.
 
MARKETING STRATEGY
 
    American  Paging directs  its marketing efforts  at value-oriented customers
who appreciate  its high  degree  of technical  reliability  and high  level  of
customer  service. American Paging's marketing  strategy is designed to increase
market share and operating  cash flow by achieving  rapid growth at modest  cost
per  net  customer unit  added. Continuing  quality improvements,  including new
services and products, help stimulate this growth while controlling costs.
 
    American Paging generates its  revenues from (i) service  usage billed on  a
flat-rate or measured-service basis, (ii) pager rentals, (iii) pager warranties,
maintenance  and  repair,  (iv)  loss  protection, (v)  voice  mail  usage  on a
flat-rate or measured-service  basis, (vi)  activation fees, (vii)  the sale  of
pager  accessories  and (viii)  service usage  of  value-added services  such as
information services, text dispatching, second telephone numbers or group calls.
Service to end users is provided directly by American Paging in most cases.
 
    American Paging  markets  its services  directly  through its  direct  sales
force,  company-owned retail stores and indirectly through third-party resellers
and agents. The direct sales staff  is responsible for the development of  large
and  medium  business  accounts  and  for  the  promotion  of  nationwide paging
services. Company-owned  retail  stores  focus on  serving  consumer  and  small
business accounts as do
 
34
<PAGE>
indirect agents. American Paging sells pagers to agents at a small mark-up or at
cost.  Agents  then  sell the  pagers  to  customers who  purchase  the services
directly from American  Paging. American  Paging provides sales  support to  its
agents, including promotional material and end-user information.
 
    American   Paging   provides  services   under  marketing   agreements  with
third-party marketing organizations, or resellers. American Paging offers paging
air time in bulk quantities at  wholesale rates to resellers who then  "re-sell"
the  air time  to end users  at a mark-up.  Resellers incur the  cost to acquire
customers as well as  to service, bill and  collect revenues from the  customer.
They  also assume  the cost of  the paging unit  for those who  rent rather than
purchase.
 
COMPETITION
 
    American Paging  faces  significant  competition  in  all  of  its  markets.
Competition for subscribers in most geographic markets American Paging serves is
based  primarily on price,  quality of services offered  and the geographic area
covered. A  number  of  American  Paging's  competitors,  which  include  local,
regional and national paging companies and certain regional telephone companies,
possess  greater financial, technical and  other resources than American Paging.
Moreover, certain competitors  in the  paging business offer  wider coverage  in
certain  geographic  areas than  does  American Paging  and  certain competitors
follow a low-price discounting strategy to  expand market share. If any of  such
companies were to devote additional resources to the paging business or increase
competitive  pressure in American Paging's markets, American Paging's results of
operations could be adversely affected.
 
    A  number  of  wireless   communication  technologies,  including   cellular
telephone service, broadband PCS, enhanced SMR and others, are competitive forms
of   technology  used  in,  or  projected  to  be  used  for,  wireless  two-way
communications.  Cellular   telephone   technology   provides   an   alternative
communications  system for customers who are  frequently away from fixed-wire or
landline communications  systems (i.e.,  ordinary telephones).  American  Paging
believes  that  paging will  remain  one of  the  lowest-cost forms  of wireless
messaging due to the low-cost infrastructure associated with paging systems,  as
well as advances in technology that will provide for reduced paging costs.
 
    Broadband  PCS  technology is  currently available  in selected  markets and
development continues  in  many  other markets  throughout  the  United  States.
Broadband  PCS Technology is  similar in design to  cellular technology and will
offer  increased  capacity  for  wireless  two-way  communication  as  well   as
short-text  messaging.  Accordingly, this  technology is  expected to  result in
increased competition for American Paging.
 
    American Paging believes the services  offered by narrowband PCS  technology
will  be  complementary  to  the  services  and  functionality  of  cellular and
broadband   PCS.   Future   technological    developments   in   the    wireless
telecommunications  industry and  the enhancement  of current  technologies will
likely create new  products and services  that are competitive  with the  paging
services  currently offered by  American Paging. There can  be no assurance that
American Paging would not be adversely affected by such technology changes.
 
REGULATION
 
    REGULATORY ENVIRONMENT.  American Paging's paging operations are subject  to
regulation  by the FCC and by state regulatory agencies. The FCC exercises broad
authority to regulate market  entry and rates  and shares responsibilities  with
state regulatory authorities over a broad range of other matters.
 
    The construction, operation and transfer of American Paging's systems in the
United  States  are regulated  to varying  degrees  by the  FCC pursuant  to the
Communications Act. 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 unnecessary.  The FCC has promulgated regulations
governing construction and operation  of wireless systems, licensing  (including
renewal  of  licenses) and  technical standards  for  the provision  of wireless
services under  the  Communications Act,  and  is implementing  the  legislative
objectives of the 1996 Act, as discussed below.
 
    LICENSING.    The  FCC  is  responsible  for  awarding  licenses  for  radio
frequencies used by American Paging and its subsidiaries to provide its  one-way
and two-way message and other service offerings. It
 
                                                                              35
<PAGE>
also establishes and enforces the licensing, technical and operating rules which
govern operations on those frequencies, the terms and conditions under which the
wireless systems of American Paging and its subsidiaries are interconnected with
and  obtain services and  facilities from other service  providers such as local
exchange carriers and others with respect to interstate services and adjudicates
any consumer or other complaints filed under the Communications Act with respect
to service providers subject to its jurisdiction.
 
    The FCC licenses granted to American Paging  are issued for up to ten  years
at  the end of which time renewal applications  must be filed with the FCC. Most
of American Paging's current licenses expire between 1998 and 2001. FCC renewals
are generally  granted so  long as  American Paging  is in  compliance with  FCC
regulations.  Although  American Paging  is unaware  of any  circumstances which
would prevent the  approval of any  pending or future  renewal applications,  no
assurance  can be given that  American Paging'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. No
license granted  to  American Paging  has  ever been  involuntarily  revoked  or
modified.
 
    The  Communications  Act requires  licensees,  such as  American  Paging, to
obtain prior approval from the FCC for the assignment or transfer of control  of
any  construction  permit  or station  license,  or any  rights  thereunder. The
Communications Act also requires  prior approval by the  FCC of acquisitions  of
other paging companies by American Paging. The FCC has approved all transfers of
control  for which  American Paging  has sought  approval. American  Paging also
routinely applies for  FCC authority  to use frequencies,  modify the  technical
parameters  of existing licenses,  expand its service  territory and provide new
services. Although  there can  be  no assurance  that  any future  requests  for
approval or applications filed by American Paging will be approved or acted upon
in  a timely manner by the FCC, or that the FCC will grant the relief requested,
American Paging has no reason to believe that any such requests, applications or
relief will not be approved or granted.
 
    Pursuant to 1993 amendments to the  Communications Act, a paging service  is
classified  as a CMRS, to the extent that it is a service offered to the public,
for a fee,  which is interconnected  to the public  switched telephone  network.
These  1993 amendments prohibit  state and local  authorities from limiting CMRS
market entry and regulating CMRS rates.
 
    RECENT EVENTS.  The FCC  adopted certain significant decisions during  1996.
In  one decision, the FCC  amended its rules to  allow paging and narrowband PCS
carriers to  offer fixed  wireless service  on a  co-primary basis  with  mobile
services.  In another decision, the FCC required that all licensees register and
obtain FCC registration numbers  for all of their  antenna towers which  require
prior  FAA clearance. The FCC also amended its environmental protection rules to
adopt new guidelines and procedures for evaluating the environmental effects  of
RF emissions.
 
    In  addition, the FCC  initiated proceedings proposing  to adopt market area
licensing to replace site-by-site licensing  of paging base stations, to  permit
geographic  partitioning and  spectrum disaggregation  in the  event market area
licensing is adopted, and to make  changes affecting the licensing of local  and
response  channels in  narrowband PCS services.  The FCC has  also announced its
intention to hold spectrum  auctions for paging and  narrowband PCS spectrum  in
1997 if its market area licensing and narrowband PCS rule revisions are adopted.
 
    The   FCC  also  established  a   phased  program  which  requires  per-call
compensation to be  paid to pay-phone  service providers by  subscribers to  800
numbers,  among others. American Paging and  numerous other paging providers who
offer 800 number calling features as a means of accessing their networks will be
required to compensate pay phone service providers under these new requirements.
 
    During 1996 the FCC implemented  significant changes in existing  regulation
of  the telecommunications industry  under the 1996 Act.  Some of these specific
changes, potentially affecting CMRS  providers, including paging and  narrowband
PCS providers, are summarized below.
 
    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
 
36
<PAGE>
proceeding  in numerous,  concurrent proceedings with  aggressive deadlines. The
Company cannot  predict the  full extent,  nature 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 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, it retains limited authority to
regulate certain competitive practices in rural telephone company service areas.
 
    Since  enactment,  the  FCC  has  adopted  orders  implementing  the   local
competition  provisions of  the 1996  Act. The  FCC found  that certain wireless
providers 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 have been taken to
the United States Court of Appeals for the Eighth Circuit from these FCC  orders
by  numerous parties alleging  that the FCC has  exceeded its statutory mandate,
among other  matters. The  Eighth Circuit  Court of  Appeals granted  a stay  of
certain  rules adopted in the  FCC orders pending its  decision on the merits of
these appeals.
 
    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.  The  FCC has  proceedings pending  to  address
recommendations  made by the  joint board with respect  to the implementation of
the universal service provisions of the 1996 Act, including, among other issues,
the size of the universal service fund and the assessment mechanism to determine
how much individual wireless carriers will be required to contribute.
 
    STATE AND LOCAL REGULATION.  The scope of state regulatory authority,  while
excluding market entry and rate regulation, covers such matters as the terms and
conditions  of  interconnection  between local  exchange  carriers  and wireless
carriers with respect to intrastate  services, customer billing information  and
practices, billing disputes, other consumer protection matters, facilities setup
issues   and  transfers  of  control,  among  other  matters.  In  these  areas,
particularly the terms and conditions of interconnection between local  exchange
carriers  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 pre-emption  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  pre-emption 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 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.
 
    American Paging and its subsidiaries have  been and intend to remain  active
participants  in proceedings before the FCC and, through its membership in state
associations  of  wireless  providers,  before  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
 
                                                                              37

among  wireless providers and  the relationships between  wireless providers and
other carriers.  American  Paging  is  unable to  predict  the  scope,  pace  or
financial impact of policy changes which could be adopted in these proceedings.
 
                               OTHER SUBSIDIARIES
 
    Subsidiaries  of the Company  provide custom printing  (Suttle Press, Inc.);

ITEM 2.  PROPERTIES
 
    The  property  of  TDS  consists  principally  of  switching  and  cell site
equipment related  to cellular  telephone operations;  telephone lines,  central
office  equipment,  telephone instruments  and related  equipment, and  land and
buildings related to  telephone operations;  and radio  pagers and  transmitting
equipment  related to  radio paging operations.  As of December  31, 1996, TDS's
gross property, plant and equipment  of approximately $2.7 billion consisted  of
the following:
 
<TABLE>
<S>                                          <C>
Cellular telephone...........................  31.8 %
Telephone....................................  48.9
PCS..........................................  12.2
Radio paging.................................   4.3
Other........................................   2.8
                                             ------
                                             100.0 %
                                             ------
                                             ------
</TABLE>
 
    The plant and equipment of TDS is maintained in good operating condition and
is  suitable and adequate for the  Company's business operations. The properties
of the operating telephone subsidiaries and  most of the tangible assets of  the
cellular  subsidiaries are  subject to  the lien  of the  mortgages securing the
funded debt of such companies. The Company owns substantially all of its central
office  buildings,  local  administrative  buildings,  warehouses,  and  storage
facilities  used in its telephone operations and  leases most of its offices and
transmitter sites  used  in its  cellular  and  paging businesses.  All  of  the
Company's  telephone lines and cell and  transmitter sites are located either on
private or public property. Locations on private land are by virtue of easements
or other arrangements.
 
- - --------------------------------------------------------------------------------
 
ITEM 3.  LEGAL PROCEEDINGS
 
    The Company is involved in a number of legal proceedings before the FCC  and
various  state  and  federal  courts. In  some  cases,  the  litigation involves
disputes regarding rights to certain landline or cellular telephone systems  and
other  interests. The Company  does not believe that  any such proceeding should
have a material adverse impact on the Company.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
                        ON FINANCIAL STATEMENT SCHEDULES
 
To the Shareholders and Board of Directors of Telephone and Data Systems, Inc.:
 
We  have audited in  accordance with generally  accepted auditing standards, the
consolidated financial statements included in  Telephone and Data Systems,  Inc.
and Subsidiaries Annual Report to Shareholders incorporated by reference in this
Form  10-K, and have  issued our report  thereon dated January  29, 1997 (except
with respect  to the  matter discussed  in  Note 16,  as to  which the  date  is
February 4, 1997). Our audits were made for the purpose of forming an opinion on
the  basic consolidated  financial statements  taken as  a whole.  The financial
statement schedules  listed  in Item  14(a)(2)  are the  responsibility  of  the
Company's  management  and  are presented  for  purposes of  complying  with the
Securities and  Exchange  Commission's rules  and  are  not part  of  the  basic
consolidated financial statements. These financial statement schedules have been
subjected  to  the  auditing  procedures  applied in  the  audits  of  the basic
consolidated financial  statements and,  in  our opinion,  fairly state  in  all
material  respects  the  financial data  required  to  be set  forth  therein in
relation to the basic consolidated financial statements taken as a whole.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF RESULTS OF OPERATIONS AND FINANCIAL CONDITION
 
    Telephone and Data Systems, Inc. ("TDS" or the "Company") provides
high-quality telecommunications services to over 2.3 million cellular telephone,
telephone and radio paging customer units in 37 states and the District of
Columbia.
 
    The accompanying financial statements present the results of operations of
the Company's three primary businesses: United States Cellular Corporation
("U.S. Cellular"), an 80.6%-owned subsidiary, TDS Telecommunications Corporation
("TDS Telecom"), a wholly owned subsidiary, and American Paging, Inc. ("American
Paging"), an 82.3%-owned subsidiary, as well as its developing personal
communications services ("PCS") business, Aerial Communications, Inc. ("Aerial",
formerly American Portable Telecom, Inc.), an 82.8%-owned subsidiary.
 
    TDS's long-term business development strategy is to expand its operations
through internal growth and acquisitions, and to explore and develop
telecommunications businesses that management believes utilize TDS's expertise
in customer-based telecommunications.
 
1996 MAJOR ACCOMPLISHMENTS
 
    The Company made substantial progress during 1996 with excellent growth in
the cellular business and the rapid build out of the PCS business. The telephone
business continues to produce steady returns and strong cash flow, while the
paging business posted disappointing results.
 
    U.S. Cellular continued its rapid growth during 1996. Customer units
increased 51%, exceeding the 1,000,000 mark, following a 69% increase in 1995.
The increase in customer units drove a 44% increase in revenues, a 48% increase
in cash flow and a 104% increase in operating income. The sale of non-strategic
cellular interests generated gains of $132.7 million and cash proceeds of $213.0
million. Capital expenditures to add cell sites, expand coverage and add
capacity totaled $219.4 million and expenditures for acquisitions totaled $56.1
million.
 
    Aerial made substantial progress building its business this year. The focus
for 1996 was directed toward recruiting an experienced management team,
developing and executing a business plan, raising capital, and designing and
constructing networks in each of its markets. These activities significantly
increased expenses in 1996. PCS development expenses (included in "Investment
and Other Income (Expense)") increased to $43.9 million in 1996 from $7.8
million in 1995. Aerial had no revenues in 1996 as commercial service is not
expected to begin until March 1997.
 
    Aerial's investment in property and equipment, including network design and
equipment, site acquisition and information system development costs, totaled
$312.6 million in 1996. To finance the development of its business, Aerial
completed an initial public offering in 1996 raising $195.3 million. Aerial also
negotiated a $200 million vendor financing arrangement for digital radio channel
and switching infrastructure equipment.
 
    TDS Telecom continues to provide steady growth in revenues and cash flow.
Telephone access lines increased 14% resulting in a 13% increase in operating
revenues, a 10% increase in cash flow and a 5% increase in operating income. TDS
Telecom's investment in outside plant facilities and upgrades of recently
acquired companies for new customer growth and new digital switches totaled
$144.4 million, and expenditures for acquisitions totaled $88.1 million.
 
    American Paging posted disappointing results for the year. During the third
quarter of 1995, American Paging launched a comprehensive restructuring
initiative relative to its sales and customer service organization. The
objectives of the restructuring were to increase sales through the direct
distribution channel, improve customer mix, lower administrative costs and
improve customer service.
 
    The disruptions caused by the restructuring were more severe than
anticipated. Customer service and sales support was affected due to the
elimination of field service employees and problems with the customer management
and billing system. Sales and marketing activities, hurt by a high level of
employee turnover, produced no customer growth resulting in a 3% decline in
revenue. The decline in revenues combined with a 21% increase in operating
expenses caused operating losses to jump to $36.6 million in 1996 from $9.0
million in 1995.
 
                                      -36-
<PAGE>
    To address these problems, American Paging appointed a new senior management
team, including a new President and CEO. The senior management team is in the
process of implementing a plan in 1997 centering on building a high quality,
focused sales and marketing organization, creating new, goal-oriented
distribution channel and pricing strategies, consolidating current systems to
reduce the cost of service and continually improving customer care practices.
 
RESULTS OF OPERATIONS
 
    Telephone and Data Systems, Inc. reported net income available to common of
$126.3 million, or $2.08 per share, in 1996 compared to $102.0 million, or $1.74
per share, in 1995 and $58.0 million, or $1.06 per share, in 1994. Results of
operations primarily reflects significant cellular business unit growth and
steady telephone operations growth. Results of operations were negatively
impacted by Aerial's development costs as it proceeds to develop and construct
its PCS networks, as well as the losses incurred by American Paging. Gains on
sales of non-strategic cellular interests and other investments had a
significant impact on net income in 1996 and 1995.
 
    Excluding PCS development costs and gains on the sales of cellular interests
and other investments, along with the related income taxes and minority
interest, net income available to common would have been $77.1 million or $1.27
per share, in 1996 compared to $68.1 million or $1.16 per share, in 1995 and
$53.2 million or $.98 per share in 1994.
 
    OPERATING REVENUES increased 27% ($260.3 million) during 1996 and 31%
($223.6 million) during 1995 primarily as a result of growth in the cellular
telephone operations.
 
    Cellular telephone revenues increased $215.4 million in 1996 and $160.0
million in 1995 on 51% and 69% increases in customer units, respectively, and
strong increases in inbound roaming revenues. Telephone revenues increased $47.8
million in 1996 and $48.5 million in 1995 as a result of acquisitions, increased
network usage, recovery of increased costs of providing long-distance services
and internal access line growth. Radio paging revenues decreased $3.0 million in
1996 and increased $15.1 million in 1995.
 
    Cellular made up 58% of consolidated revenue in 1996, up from 45% in 1994.
Telephone and paging operations were 33% and 9% of consolidated revenue in 1996
and 42% and 13% in 1994, respectively.
 
    OPERATING EXPENSES rose 29% ($238.2 million) in 1996 and 32% ($200.4
million) in 1995. Cellular telephone operating expenses increased $170.8 million
during 1996 and $134.6 million during 1995 due to the effects of additional
marketing and selling expenses to add new customers as well as the costs of
providing services to the larger customer base. Telephone operating expenses
increased $42.7 million during 1996 and $41.9 million during 1995 due to the
effects of acquisitions and growth in internal operations. Paging operating
expenses increased $24.7 million in 1996 and $23.9 million in 1995 due to
additional expenses to restructure certain business processes and additional
costs to serve current customers and to add new customers.

    OPERATING INCOME increased 17% ($22.1 million) in 1996 and 21% ($23.2
million) in 1995. Cellular telephone operating income increased 104% ($44.6
million) in 1996 and 146% ($25.4 million) in 1995 reflecting the increase in
customers and revenues. Telephone operating income increased $5.1 million in
1996 and $6.6 million in 1995. Paging operating loss increased $27.6 million in
1996 and $8.8 million in 1995.

</TABLE>
 
    In early 1997, Aerial expects to begin commercial service which will result
in Aerial's revenues and expenses being included in operating income. Operating
income is expected to decrease significantly in 1997 as a result of the
commencement of PCS operations.
 
    INVESTMENT AND OTHER INCOME totaled $140.5 million in 1996, $103.9 million
in 1995 and $33.7 million in 1994.
 
    CELLULAR INVESTMENT INCOME, the Company's share of income of cellular
markets in which the Company has a minority interest and follows the equity
method of accounting, increased 33% ($13.5 million) in 1996 and 56% ($14.6
million) in 1995 as income from the cellular markets increased. Cellular
investment income is net of amortization of license costs relating to these
minority interests.
 
    GAIN ON SALE OF CELLULAR INTERESTS AND OTHER INVESTMENTS totaled $138.7
million in 1996, $86.6 million in 1995 and $7.5 million in 1994. TDS and U.S.
Cellular continue to assess the makeup of cellular holdings in order to maximize
the benefits derived from clustering markets. Certain markets, identified as
non-strategic, were sold or traded in the past few years resulting in the
recognition of gains.
 
    PCS DEVELOPMENT COSTS totaled $43.9 million in 1996 and $7.8 million in
1995. Aerial has been devoting substantially all of its efforts to recruiting an
experienced management team, developing and executing a business plan, raising
capital, and designing and constructing its PCS networks. Costs incurred in the
development and administration of Aerial which do not relate to the design or
construction of specific identifiable assets have been expensed.
 
    MINORITY SHARE OF INCOME, the minority shareholders' share of U.S.
Cellular's, American Paging's and Aerial's net income or loss and other minority
shareholders' and partners' share of subsidiaries' net income or loss, increased
$800,000 in 1996 and $16.8 million in 1995.
 
    INTEREST EXPENSE decreased 16% ($8.0 million) in 1996 and increased 23%
($9.6 million) in 1995. Capitalized interest associated with expenditures for
PCS licenses and capitalized construction costs increased $14.4 million in 1996
and $13.2 million in 1995. Interest expense increased $6.9 million in 1996 and
$7.4 million in 1995 as a result of U.S. Cellular's convertible debt offering in
June of 1995. Interest expense from U.S. Cellular's vendor financing agreement
increased $5.3 million in 1995. TDS Telecom interest expense increased $1.2
million in 1996 and $1.4 million in 1995 due primarily to additional interest
expense of acquired telephone companies.
 
    Corporate interest expense decreased $2.0 million in 1996 and increased $8.6
million in 1995 reflecting primarily changes in average short-term debt
balances. See "Financial Resources and Liquidity" for a further discussion of
short- and long-term debt.

    TDS capitalized $27.6 million of interest expense in 1996 and $13.2 million
in 1995. Interest expense will increase significantly in 1997 when TDS
discontinues capitalizing interest upon commencement of Aerial's operations.
 
    INCOME TAX EXPENSE increased 53% ($42.6 million) in 1996 and 99% ($40.3
million) in 1995, reflecting primarily the 36% and 83% increases in pretax
income, respectively. The effective income tax rates were 49% in 1996, 44% in
1995 and 40% in 1994. The increase in the 1996 effective tax rate reflects
additional income tax expense of approximately $10.0 million due to tax gains in
excess of book gains associated with the sale of certain cellular interests. The
lower 1994 rate reflects deferred income taxes provided on the book/tax basis
difference related to certain telephone acquisitions and certain income excluded
due to the dividend exclusion rules.
 
    NET INCOME AVAILABLE TO COMMON was $126.3 million in 1996, $102.0 million in
1995 and $58.0 million in 1994. EARNINGS PER COMMON SHARE were $2.08 in 1996,
$1.74 in 1995 and $1.06 in 1994.
 
    Net income available to common for 1996 and 1995 included significant gains
from the sale of cellular interest and other investments as well as significant
PCS development costs. The table below summarizes the effects of the gains and
PCS development costs (along with the related impact on income taxes and
minority interest) on net income available to common and earnings per share.

    OPERATING REVENUES increased 44% ($215.4 million) in 1996 and 48% ($160.0
million) in 1995. The revenue increases in 1996 and 1995 were driven by the 51%
and 69% growth in customer units and the 31% and 42% growth in inbound roaming
revenues, respectively. Acquisitions, which were not material in 1996, increased
operating revenues 13% ($44.2 million) in 1995. Average monthly revenue per
customer was $66.36 in 1996, $72.48 in 1995 and $79.74 in 1994.
 
    LOCAL RETAIL REVENUE (charges to U.S. Cellular's customers for local system
usage) increased 53% ($153.0 million) in 1996 and 54% ($101.5 million) in 1995
due primarily to the 51% and 69% growth in customers, respectively. Local
minutes of use averaged 107 per month in 1996 and 95 per month in 1995 and 1994.
Average revenue per minute was $.40 in 1996, $.46 in 1995 and $.50 in 1994. U.S.
Cellular's use of incentive programs in 1996 and 1995 that encourage
lower-priced weekend and off-peak usage, in order to stimulate overall usage,
resulted in an increase in average minutes of use and a lower average revenue
per minute of use. Average monthly local retail revenue per customer was $42.54
in 1996, $44.03 in 1995 and $47.04 in 1994.

    INBOUND ROAMING REVENUE (charges to customers of other systems who use U.S.
Cellular's cellular systems when roaming) increased 31% ($45.3 million) in 1996
and 42% ($44.0 million) in 1995 due to increased minutes of use. Minutes of use
increased 38% in 1996 and 60% in 1995. Average revenue per minute of use was
$.94 in 1996, $.99 in 1995 and $1.11 in 1994. Average monthly inbound roaming
revenue per U.S. Cellular customer was $18.58, $22.51 and $26.03 in 1996, 1995
and 1994, respectively. The decrease is the result of roaming revenue growing at
a slower rate than U.S. Cellular's customer base and negotiated reductions in
roaming rates.
 
    LONG-DISTANCE AND OTHER REVENUE, including equipment sales, increased 31%
($17.1 million) in 1996 and 36% ($14.4 million) in 1995 primarily due to
increased long-distance revenue from the growth in the volume of long-distance
calls billed by U.S. Cellular.
 
    The industry trend of declining average monthly retail revenue per customer
is believed to be related to the tendency of early customers in a market to be
the heaviest users during peak business hours. Newer customers have been added
through continued penetration of the consumer market, which tends to include
fewer peak business hour usage customers.
 
    Management anticipates that average monthly revenue per customer will
continue to decrease as local retail revenue per minute of use declines due to
the usage patterns of incrementally added customers and as the growth rate of
the Company's customer base exceeds the growth rate of inbound roaming revenue,
diluting the roaming contribution per customer.
 
    OPERATING EXPENSES increased 38% ($170.8 million) in 1996 and 43% ($134.6
million) in 1995. Acquisitions, which were not material in 1996, increased
operating expenses 13% ($40.7 million) in 1995. The increase in operating
expenses, excluding acquisition effects, is primarily due to the costs to expand
the customer base ($66.7 million in 1996 and $33.6 million in 1995); cost of
providing service to the expanding customer base ($46.9 million in 1996 and
$16.0 million in 1995); increased administrative expenses ($37.8 million in 1996
and $27.1 million in 1995) additional depreciation on the increased investment
in cell sites and equipment ($17.3 million in 1996 and $13.2 million in 1995)
and additional fraud charges ($13.9 million in 1996).
 
    SYSTEM OPERATIONS EXPENSES increased 67% ($46.9 million) in 1996 and 50%
($23.6 million) in 1995 (34%, or $16.0 million excluding acquisitions) as a
result of increases in customer usage expenses, including significant increases
in fraud, and costs associated with operating the increased number of cell
sites.
 
    Customer usage expenses (charges from other service providers for land line
connection, toll and roaming costs incurred by customers' use of systems other
than their local systems) grew 86% ($26.6 million) in 1996 and 62% ($13.4
million) in 1995. The increase was due primarily to inbound roaming usage.
 
    Fraudulent use of U.S. Cellular's customers' telephone numbers increased
expenses $13.9 million to $18.0 million in 1996. U.S. Cellular continues to
implement procedures in its markets to combat this fraud, which is primarily
related to roaming usage.
 
    Maintenance, utility and cell site expenses grew 18% ($6.5 million) in 1996
and 40% ($10.2 million) in 1995 reflecting the 19% and 41% increase in the
number of cell sites, respectively. The number of cell sites operated increased
to 1,328 in 1996 from 1,116 in 1995 and 790 in 1994.
 
    MARKETING AND SELLING EXPENSES increased 47% ($47.6 million) in 1996 and 48%
($33.3 million) in 1995 (35%, or $24.3 million excluding acquisitions) due to
the increase in customer activations. COST OF EQUIPMENT SOLD increased 35%
($19.1 million) in 1996 and 39% ($15.5 million) in 1995 (23%, or $9.3 million
excluding acquisitions). Cost per gross customer addition (marketing and selling
expenses and cost of equipment sold less equipment revenues, divided by gross
customer additions) totaled $367 in 1996, $361 in 1995 and $408 in 1994.
 
    GENERAL AND ADMINISTRATIVE EXPENSES increased 29% ($37.8 million) in 1996
and 41% ($38.2 million) in 1995 (29%, or $27.1 million excluding acquisitions).
The increases include the effects of an increase in expenses required to serve
the growing customer base and an expansion of both local administrative office
and corporate staff, resulting from growth in U.S. Cellular's business.

    Operating cash flow increased 48% to $196.2 million in 1996 compared to a
60% increase to $132.2 million in 1995. The improvement was primarily due to the
growth in customers and revenue. U.S. Cellular continues to provide increasing
operating cash flow to support its operating and construction activities.
 
    DEPRECIATION EXPENSE increased 30% ($17.3 million) in 1996 and 45% ($17.8
million) in 1995 (33%, or $13.2 million excluding acquisitions), reflecting
increases in average fixed asset balances of 34% and 48%, respectively.
AMORTIZATION EXPENSE increased 6% ($2.1 million) in 1996 and 24% ($6.2 million)
in 1995 (15%, or $4.0 million excluding acquisitions) due to increases in
deferred systems development costs in both years and license costs in 1995.
 
    OPERATING INCOME was $87.4 million in 1996 compared to $42.8 million in 1995
and $17.4 million in 1994. Operating margins improved to 12.3% in 1996 from 8.7%
in 1995 and 5.2% in 1994. The improvement was primarily due to the substantial
growth in customers and revenue.
 
    Management believes there exists a seasonality at U.S. Cellular in both
service revenues, which tend to increase more slowly in the first and fourth
quarters, and operating expenses, which tend to be higher in the fourth quarter
due to increased marketing activities and customer growth. This seasonality may
cause operating income to vary from quarter to quarter.
 
    Competitors licensed to provide PCS services have initiated service in
certain U.S. Cellular markets in recent months. U.S. Cellular anticipates that
PCS operators will initiate service in several other of its markets in 1997 and
1998. U.S. Cellular's management is monitoring these and other PCS providers'
strategies, but cannot at this time anticipate what effect, if any, this
additional competition will have on U.S. Cellular's future strategies and
results.
 
TELEPHONE OPERATIONS
 
    TDS manages its telephone service through TDS Telecommunications Corporation
("TDS Telecom"). TDS Telecom served 484,500 access lines at the end of 1996
compared to 425,900 access lines at the end of 1995 and 392,500 access lines at
the end of 1994 ("telephone operations"). TDS Telecom also manages a
long-distance provider, an Internet access provider and certain other
non-telephone operations ("other operations").
 
    OPERATING REVENUE totaled $402.6 million in 1996, up 13% ($47.8 million)
from 1995 and totaled $354.8 million in 1995, up 16% ($48.5 million) from 1994.
The increases were due to the growth in telephone operations ($39.6 million in
1996 and $35.6 million in 1995) and additional other operations revenues ($8.0
million in 1996 and $13.3 million in 1995).
 
    OPERATING EXPENSES totaled $299.3 million in 1996, up 17% ($42.7 million)
from 1995 and totaled $256.6 million in 1995, up 19% ($41.9 million) from 1994.
The increases were due to the growth in telephone operations ($33.6 million in
1996 and $29.8 million in 1995) and additional other operations expenses ($8.9
million in 1996 and $12.3 million in 1995).
 
    Operating cash flow increased 10% to $192.3 million in 1996 compared to an
increase of 9% to $175.6 million in 1995 due primarily to the growth in
telephone operations. TDS Telecom continues to provide steadily growing
operating cash flow to support its construction activities.
 
    OPERATING INCOME increased 5% ($5.1 million) in 1996 and increased 7% ($6.6
million) in 1995. The reduction in the growth rate of operating income was
caused by the the reduction in the telephone operating margins and other
operations margins.
 
                                      -42-
<PAGE>
    Management expects TDS Telecom's revenues, operating income and operating
cash flow to increase modestly in 1997 from steady growth in operations. TDS
Telecom will continue to see pressures on revenue sources resulting from
regulatory changes and competitive pressures.

    OPERATING REVENUE from telephone operations increased 12% ($39.6 million) in
1996 and 12% ($35.6 million) in 1995. Acquisitions increased telephone revenues
$18.8 million in 1996 and $16.8 million in 1995. Internal growth and increases
in the sales of custom calling features increased revenue by $8.0 million in
1996 and $6.0 million in 1995. Increased network usage resulted in revenue
increases of $4.5 million in 1996 and $5.8 million in 1995. Recovery of
increased costs of providing long-distance services resulted in increases in
revenue of $8.1 million in 1996 and $4.5 million in 1995. Average monthly
revenue per access line was $67.12 in 1996, $66.87 in 1995 and $66.66 in 1994.
 
    OPERATING EXPENSES from telephone operations increased 14% ($33.6 million)
in 1996 and 15% ($29.8 million) in 1995. The effects of acquisitions increased
expenses 6% ($14.6 million) in 1996 and 7% ($13.8 million) in 1995. Depreciation
and amortization expenses increased 14% ($10.8 million) in 1996 and 10% ($6.8
million) in 1995 due primarily to increased investment in plant and equipment.
The development of a centralized network management center to provide more
effective network monitoring and maintenance and the development of groups to
explore new service offerings caused expenses to increase by $3.4 million and
$3.2 million, respectively, in 1996. These expenditures are expected to begin
producing cost efficiencies and new revenues in the next several quarters and
beyond. Additional routine maintenance activity and equipment write-offs
increased network expenses by $2.0 million in 1995. The remaining increase in
each year was due primarily to growth in internal operations.

    OPERATING INCOME from telephone operations increased 6% ($6.0 million) in
1996 and increased 6% ($5.7 million) in 1995. The effects of acquisitions
increased operating income 4% ($4.2 million) in 1996 and 3% ($3.0 million) in
1995. The telephone operating margin was 27.6% in 1996, 29.1% in 1995 and 30.7%
in 1994. The reduction in operating margin was caused by earnings pressures from
regulatory agencies and long-distance providers and increased costs associated
with the development of the centralized network management center.
 
    TDS Telecom is subject to the provisions of Statement of Financial
Accounting Standards ("SFAS") No. 71, "Accounting for the Effects of Certain
Types of Regulation." The Company periodically reviews the criteria for applying
these provisions to determine whether continuing application of SFAS No. 71 is
appropriate. The Company believes that such criteria are still being met and
therefore has no current plans to change its method of accounting.
 
    In analyzing the effects of discontinuing the application of SFAS No. 71,
management has determined that the useful lives of plant assets used for
regulatory and financial reporting purposes are consistent with generally
accepted accounting principles and therefore any adjustments to accumulated
depreciation would be immaterial, as would be the write-off of regulatory assets
and liabilities.
 
RADIO PAGING OPERATIONS
 
    TDS manages its radio paging business through American Paging, Inc. [AMEX:
APP]. American Paging provided wireless messaging communications through its
digital radio transmission systems to 777,400 subscribers at the end of 1996
compared to 784,500 subscribers at the end of 1995 and 652,800 subscribers at
the end of 1994.
 
    American Paging posted disappointing results for the year. During the third
quarter of 1995, American Paging launched a comprehensive restructuring
initiative relative to its sales and customer service organization. The
objectives of the restructuring were to increase sales through the direct
distribution channel, improve customer mix, lower administrative costs and
improve customer service. The restructuring initiative continued through 1996,
and had a more severe impact on American Paging's results of operations than
anticipated.
 
    An integral part of the restructuring plan included the creation of a
Customer Telecare Center ("CTC"). The consolidation and transfer of back office
and customer service operations from 17 offices to the CTC created many
disruptions throughout American Paging. The process of eliminating field
administrative personnel and moving their duties to the CTC hurt customer
service and sales support due to early inefficiencies encountered in the
operation of the CTC. During the consolidation, it also became apparent that the
customer management and information system did not provide the flexibility
needed to support future customer growth and retention. American Paging is
currently assessing two potential customer management and billing systems.
 
    Disruptions within the sales and marketing department led to an increase in
sales employee turnover which produced no customer growth and contributed to a
3% decline in revenue. The decline in revenues combined with a 21% increase in
expenses caused operating losses to jump to $36.6 million in 1996 from $9.0
million in 1995.
 
    To address these problems, American Paging appointed a new senior management
team, including a new President and CEO. The senior management team began
implementing a plan in 1997 centering on building a high quality, focused sales
and marketing organization, creating new, goal-oriented distribution channel and
pricing strategies, consolidating current systems to reduce the cost of service
and continually improving customer care practices.

</TABLE>
 
    OPERATING REVENUES decreased 3% ($3.0 million) in 1996 primarily as a result
of a 27% ($3.8 million) decline in equipment sales. Operating revenues increased
16% ($15.1 million) in 1995, primarily as a result of a 20% increase in the
number of pagers in service.
 
    Average monthly revenue per unit declined 7% to $9.88 in 1996 and 11% to
$10.57 in 1995. The decline in average revenue per unit reflects competitive
pressures in 1996 and 1995 as well as a shift to lower revenue producing
reseller channels in 1995. As a part of the restructuring efforts, American
Paging is refocusing its marketing strategy to the higher revenue producing
direct distribution channel.
 
    OPERATING EXPENSES increased 21% ($24.7 million) in 1996 and 26% ($23.9
million) in 1995. Restructuring costs totaled $9.3 million in 1996 and $2.9
million in 1995. Duplicate staffing, employee severance and legal and consulting
fees, included in selling, general and administrative expense, totaled $4.0
million in 1996 and $2.1 million in 1995. Write-offs of $5.3 million for
obsolete inventory, software and other assets, included in depreciation and
amortization expense, were recorded in 1996. During 1995, an $800,000 write-off
of assets retired was incurred as a result of the restructuring.
 
    Operating expenses, excluding restructuring costs, increased 16% ($18.2
million) in 1996 and 23% ($21.0 million) in 1995. Costs of serving the customer
base and maintaining systems to provide system reliability and coverage
increased 25% ($6.0 million) in 1996 and 24% ($4.7 million) in 1995. Selling,
general and administrative expense increased 23% ($11.8 million) in 1996 and 24%
($10.0 million) in 1995. The cost per gross customer addition, excluding
customers added through acquisitions, was $94 in 1996 compared to $50 in 1995
and $41 in 1994. The large increase was due to the slow unit growth caused by
high employee turnover in the sales function coupled with the increase in sales
and marketing costs. Depreciation and amortization charges increased 19% ($4.6
million) in 1996 and 39% ($6.7 million) in 1995, reflecting increased investment
in pagers and related equipment. A change in useful lives of pagers and
transmitters adopted in 1994 increased depreciation expense by approximately
$1.7 million in 1995.
 
    OPERATING LOSS was $36.6 million in 1996, $9.0 million in 1995 and $200,000
in 1994. Management expects American Paging to have modest success in attracting
and retaining new customers and holding down operating expenses. However,
management anticipates that American Paging will incur significant operating
losses again in 1997.
 
    BROADBAND PERSONAL COMMUNICATIONS SERVICES TDS manages its broadband
personal communications services business through Aerial Communications, Inc.
[NASDAQ: AERL], formerly American Portable Telecom, Inc. Aerial's licenses
include the Major Trading Areas ("MTAs") of Minneapolis, Tampa-St.
Petersburg-Orlando, Houston, Pittsburgh, Kansas City and Columbus with 27.6
million population equivalents.
 
    Aerial's focus in 1996 has been the development of its PCS business in its
MTAs. This focus will continue until the expected launch of commercial service
in early 1997. As of December 31, 1996, a total of 150
 
                                      -45-
<PAGE>
microwave paths have been cleared, with an additional 39 paths having agreements
with incumbents to be cleared. Management believes that sufficient paths have
been cleared to allow service launch in all six markets. Over 600 cell sites
have been secured as zoning and installation work continues. The National
Operations Center in Tampa is complete. Friendly user (customer) trials are
planned to conclude in the first quarter of 1997, with roll-out of commercial
service after successful customer trials.
 
    Upon commencement of commercial operations, Aerial's revenues and expenses
will be included in operating income. Management expects to incur significant
expenditures for the continued development of PCS activities and start-up
operating losses during 1997.
 
    To finance the development of its business, Aerial completed an initial
public offering in 1996 raising $195.3 million. Aerial also negotiated a $200
million vendor financing arrangement for digital radio channel and switching
infrastructure equipment. As part of the vendor financing arrangement, Aerial
issued 10-year 8.34% Series A Zero Coupon Notes due in 2006 for $100 million of
digital radio channel and switching equipment.
 
INFLATION
 
    Management believes that inflation affects TDS's business to no greater
extent than the general economy.
 
FINANCIAL RESOURCES
 
    TDS and its subsidiaries operate relatively capital-intensive businesses.
Rapid growth has caused expenditures for construction, expansion and acquisitio
programs to exceed internally generated cash flow. Accordingly, TDS has obtained
substantial funds from external sources to finance construction of cellular
telephone systems, to acquire PCS licenses, to build-out PCS markets and to fund
acquisitions. Although the steady internal cash flow from TDS Telecom and
increasing internal cash flow from U.S. Cellular have reduced the need for
external financing, Aerial's development and construction activities will
require substantial additional funds from external sources.
 
    CASH FLOWS FROM OPERATING ACTIVITIES.  TDS is generating substantial
internal funds from the rapid growth in customer units and revenues. Operating
cash flow (operating income plus depreciation and amortization) increased 19%
($62.2 million) to $385.7 million in 1996, and 24% ($63.2 million) to $323.5
million in 1995. The increases represent primarily cellular telephone operations
increases of 48% ($64.0 million) in 1996 and 60% ($49.4 million) in 1995. Cash
flows from other operating activities (investment and other income, interest and
income tax expense, and changes in working capital and other assets and
liabilities) required $90.7 million in 1996, $112.6 million in 1995, and $35.6
million in 1994.

    CASH FLOWS FROM FINANCING ACTIVITIES.  TDS' long-term strategy is to provide
a strong yet flexible financial foundation for each of its principal
subsidiaries. Consolidated equity capital (common equity, preferred stock and
minority interest) was 68% of total capitalization at December 31, 1996,
compared to 73% at December 31, 1994. The change is primarily a result of
significant increases in long-term debt at U.S. Cellular and Aerial as well as
increases in TDS short-term debt. TDS targets a ratio of equity to total capital
in the range of 55% to 65%.
 
                                      -46-
<PAGE>
    TDS has used short-term debt to finance its PCS, cellular telephone and
radio paging operations, for acquisitions and for general corporate purposes.
TDS takes advantage of attractive opportunities to retire short-term debt with
the proceeds from long-term debt, equity sales and sales of non-strategic
assets.
 
    In 1996, Aerial received $195.3 million in an initial public offering of
Common Shares. In 1995, U.S. Cellular received approximately $221.5 million from
the sale of 20-year 6% zero coupon convertible debt and TDS sold $39.2 million
of Medium-Term Notes. In 1994, American Paging received $45.6 million in an
initial public offering of its Common Shares and TDS sold Common Shares for cash
totaling $4.9 million.
 
    Aerial, U.S. Cellular and TDS Telecom have also used long-term debt to
finance their construction and development activities. In 1996, Aerial issued
10-year 8.34% zero coupon notes for $100 million of digital radio channel and
switching equipment. U.S. Cellular financed cellular system equipment and
construction costs totaling $59.5 million in 1995 and $18.0 million in 1994
under vendor financing arrangements. TDS Telecom telephone subsidiaries borrowed
$12.2 million in 1996, $12.0 million in 1995 and $16.8 million in 1994 under the
Rural Utility Service and the Rural Telephone Bank long-term federal government
loan programs to finance their telephone construction programs.
 
    CASH FLOWS FROM INVESTING ACTIVITIES.  TDS makes substantial investments
each year to acquire, construct, operate and maintain modern high-quality
communications networks and facilities with the intention of exceeding its
customers expectations as a basis for creating long-term value for shareowners.
In recent years, rapid changes in technology and new opportunities have required
substantial investments in revenue enhancing and cost reducing upgrades of the
Company's networks.
 
    Cash expenditures for property, plant and equipment additions totaled $550.2
million in 1996, $360.0 million in 1995 and $319.7 million in 1994. In addition,
the acquisition and development of broadband and narrowband PCS licenses
required $26.5 million in 1996, $326.0 million in 1995 and $31.6 million in
1994. Cash used for acquisitions, excluding cash acquired, totaled $31.0 million
in 1996, $53.8 million in 1995 and $37.6 million in 1994. The sale of
non-strategic cellular assets and other investments provided $221.5 million in
net proceeds in 1996, $197.6 million in 1995 and $6.0 million in 1994.
 
PROPERTY, PLANT AND EQUIPMENT
 
    The primary purpose of TDS's construction and expansion program is to
provide for significant customer growth, to upgrade service, to expand into new
communication areas, and to take advantage of service-
 
                                      -47-

enhancing and cost-reducing technological developments. In 1996, the Company
invested a significant amount of money to develop and construct Aerial's
systems. The following table summarizes the Company's investments in its
communications networks and related facilities during the past three years.

</TABLE>
 
    U.S. Cellular's capital additions include expenditures to add additional
cell sites and radio channels to expand coverage and add capacity. U.S. Cellular
constructed 242 cell sites in 1996, 292 in 1995 and 225 in 1994. TDS Telecom's
capital additions include expenditures for outside plant facilities and upgrades
of recently acquired companies for new customer growth and switch modernization.
TDS Telecom installed 35 digital switches in 1996, 39 in 1995 and 32 in 1994.
Aerial has completed the construction of the five planned switching centers and
the central Network Operations Center, cleared over 150 microwave paths and is
building over 600 cell sites.
 
    The Company's expected 1997 property, plant and equipment additions reflect
the Company's construction and expansion programs and are anticipated to
aggregate approximately $810 million. In addition, Aerial's working capital and
operating expenses will require an estimated $255 million.
 
    - The cellular capital additions budget totals approximately $300 million,
      including about $258 million for new cell sites and about $30 million for
      various information systems initiatives.
 
    - The telephone capital additions budget totals approximately $130 million,
      including about $56 million for new digital switches and other switching
      facilities and $56 million for improvements to outside plant facilities.
 
                                      -48-

    - The PCS capital additions budget totals approximately $345 million,
      including $255 million for switching equipment and $38 million for cell
      sites. In addition, Aerial's working capital and operating expenses will
      require an estimated $255 million.
 
    - The radio paging capital additions are anticipated to total about $35
      million, including $15 million for systems and transmitters and $16
      million for pagers.
 
    The Company expects to finance the budgeted additions to property, plant and
equipment primarily with internally generated cash, short-term and
intermediate-term financing, vendor financing and the sale of minority equity
interests in Aerial's MTAs to strategic investors.

    The Company continually reviews attractive opportunities for the acquisition
of additional cellular and telephone companies.
 
    TDS and U.S. Cellular continue to assess the makeup of cellular holdings in
order to maximize the benefits derived from clustering U.S. Cellular's markets.
As the number of opportunities for outright acquisitions of cellular interests
has decreased and as U.S. Cellular's clusters have grown to realize greater
economies of scale, U.S. Cellular's focus has shifted toward exchanges and sales
of non-strategic interests.
 
    In February 1997, U.S. Cellular announced that it had entered into an
exchange agreement with BellSouth Corporation, pursuant to which U.S. Cellular
will receive controlling interests in twelve contiguous markets adjacent to its
Iowa and Wisconsin/Illinois clusters. In exchange, U.S. Cellular will transfer
its controlling interests in ten markets, investment interests in 13 markets and
pay cash, the amount of which is dependent upon certain factors. U.S. Cellular
will receive controlling interests representing approximately 3.9 million
population equivalents ("pops") in the transaction, and will divest controlling
interests representing approximately 1.9 million pops and investment interests
representing 1.4 million pops. The transaction is subject to various regulatory
and other approvals.
 
    U.S. Cellular expects that the completion of this transaction will have a
positive effect on its consolidated operations after the transition of operators
is complete. The transaction is also expected to significantly reduce investment
income immediately after it is completed. Because of the uncertainty of the
regulatory approval process, U.S. Cellular cannot estimate when the transaction
will be completed.

LIQUIDITY
 
    The Company anticipates that the aggregate resources required for 1997 will
include approximately $810 million for capital spending and $255 million for
working capital and operating expenses for Aerial.
 
    The Company is generating substantial internal funds from the rapid growth
in customer units and revenues. Operating cash flow (operating income plus
depreciation and amortization), primarily from cellular and telephone
operations, increased to $385.7 million in 1996 from $323.5 million in 1995 and
$260.3 million in 1994.
 
    U.S. Cellular plans to finance its construction program primarily with
internally generated cash supplemented by short-term and intermediate-term
financing. TDS Telecom plans to finance its $130 million construction program
using internally generated cash supplemented by long-term financing from federal
government programs.
 
    Aerial plans to finance its construction expenditures and working capital
requirements with short-term and intermediate-term financing, vendor financing
and sales of minority equity interests in MTAs to strategic investors.
 
    TDS and its subsidiaries have cash and temporary investments totaling $119.3
million and longer-term investments totaling $32.4 million at December 31, 1996.
These investments are primarily the result of telephone operations' internally
generated cash. While certain regulated telephone subsidiaries' debt agreements
place limits on intercompany dividend payments, these restrictions are not
expected to affect the Company's ability to meet its cash obligations.
 
    TDS and its subsidiaries also have access to a variety of external capital
sources. TDS and its subsidiaries had $653 million of bank lines of credit for
general corporate purposes at December 31, 1996. Unused amounts of such lines
totaled $496 million. These line of credit agreements provide for borrowings at
negotiated rates up to the prime rate.
 
    TDS has a universal shelf registration statement which may be used from time
to time to issue debt securities and/or Common Shares for cash. As of December
31, 1996, $238.4 million remained unused on the universal shelf.
 
    TDS and U.S. Cellular have shelf registration statements covering the
issuance of equity for acquisitions. In addition, the Company has issued Common
Shares for acquisitions pursuant to registration statements filed specifically
for particular acquisitions.
 
    In December 1996, the Company authorized the repurchase of up to 3.0 million
TDS Common Shares over a period of three years. The Company plans to finance the
repurchase program using internally generated funds and borrowings under
short-term lines of credit. The Company may use repurchased shares to fund
acquisitions and for general corporate purposes. Subject to prevailing market
conditions, purchases may be made from time to time through open market
purchases or at negotiated prices in private transactions. The actual number of
Common Shares which may be repurchased will be subject to the trading price of
the Common Shares, the Company's financial position and other factors.
 
    The Company anticipates requiring additional funding to finance Aerial's
expected capital expenditures and working capital requirements, to finance
acquisitions and for general corporate purposes. The timing and amount of such
funding requirements will depend on the timing of the completion of Aerial's
construction and operational plans, the timing of acquisitions, and other
relevant factors. There can be no assurance that sufficient funds will be
available to the Company on terms or at prices acceptable to the Company. If
sufficient funding is not made available to the Company on terms and prices
acceptable to the Company, the Company would have to reduce its construction,
development and acquisition programs. TDS and its subsidiaries anticipate
accessing public and private capital markets to issue debt and equity securities
only when capital requirements, financial market conditions and other factors
warrant.

NOTE 1
 
    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    The accounting policies of Telephone and Data Systems, Inc. and its
subsidiaries ("TDS" or the "Company") conform to generally accepted accounting
principles. The accounting records of the telephone subsidiaries are maintained
in accordance with the uniform systems of accounts prescribed by the regulatory
bodies under whose jurisdiction the subsidiaries operate.
 
    NATURE OF OPERATIONS
 
    TDS is a diversified telecommunications company which, at December 31, 1996,
provided high-quality telecommunications services to approximately 2.3 million
cellular telephone, telephone and radio paging customers in 37 states and the
District of Columbia. The Company conducts substantially all of its cellular
operations through its 80.6%-owned subsidiary, United States Cellular
Corporation [AMEX:USM], its telephone operations through its wholly owned
subsidiary, TDS Telecommunications Corporation ("TDS Telecom"), and its radio
paging operations through its 82.3%-owned subsidiary, American Paging, Inc.
[AMEX:APP]. The Company is developing its personal communications services
("PCS") operations through its 82.8%-owned subsidiary Aerial Communications,
Inc. [NASDAQ:AERL] (formerly American Portable Telecom, Inc.). PCS development
costs for each of the three years ended December 31, 1996 are set forth in the
Consolidated Statements of Income. See Note 14-Business Segment Information for
summary financial information on each business segment.
 
    PRINCIPLES OF CONSOLIDATION
 
    The consolidated financial statements include the accounts of TDS, its
majority-owned subsidiaries since acquisition and the cellular telephone
partnerships in which TDS has a majority general partnership interest. All
material intercompany items have been eliminated. Certain amounts reported in
prior years have been reclassified to conform to current period presentation.
 
    TDS includes as investments in subsidiaries the value of the consideration
given and all direct and incremental costs relating to acquisitions accounted
for as purchases. All costs relating to unsuccessful negotiations for
acquisitions are expensed.
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
    CASH AND CASH EQUIVALENTS AND TEMPORARY INVESTMENTS
 
    Cash and cash equivalents include cash and those short-term, highly-liquid
investments with original maturities of three months or less. Those investments
with original maturities of more than three months to 12 months are classified
as temporary investments. Temporary investments are stated at cost, which
approximates market. Those investments with original maturities of more than 12
months are classified as marketable securities and are stated at amortized cost.
 
    INVESTMENTS
 
    Cellular license acquisition costs consist of costs incurred in acquiring
Federal Communications Commission ("FCC") licenses or minority interests which
have been awarded FCC licenses to provide cellular service. These costs include
amounts paid to license applicants and owners of interests in cellular entities
awarded licenses; amounts paid for legal, engineering, and consulting services;
amounts incurred by TDS in acquiring these interests; and goodwill. These costs
are capitalized and amortized through charges to expense over 40 years upon
commencement of operations. Amortization amounted to $28.5 million, $27.8

million and $24.2 million in 1996, 1995 and 1994, respectively. Accumulated
amortization of cellular license costs was $112.2 million and $90.6 million at
December 31, 1996 and 1995, respectively. Included in cellular license costs is
approximately $322 million and $363 million at December 31, 1996 and 1995,
respectively, of goodwill which resulted from various acquisitions structured to
be tax-free.
 
    Investments in cellular minority interests consist of amounts invested in
cellular entities in which TDS holds a minority interest. The Company follows
the equity method of accounting, which recognizes TDS's proportionate share of
the income and losses accruing to it under the terms of its partnership or
shareholder agreements, for its long-term investments ($196.0 million and $146.1
million at December 31, 1996 and 1995, respectively). Income and losses from
these entities are reflected in the consolidated income statements on a pretax
basis. At December 31, 1996, the cumulative share of income from minority
cellular investments accounted for under the equity method was $184.3 million,
of which $94.7 million was undistributed. The cost method of accounting is
followed for certain minority interests managed by others ($10.4 million and
$12.5 million at December 31, 1996 and 1995, respectively).
 
    Broadband and Narrowband PCS license acquisition costs consist of costs
incurred in acquiring PCS licenses ($341.8 million) and capitalized interest
($39.6 million). These costs will be amortized through charges to expense upon
commencement of operations.
 
    Telephone franchise and other costs include the costs in excess of the
underlying book value of acquired telephone companies. Costs in excess of the
underlying book value relating to acquisitions initiated before November 1,
1970, aggregating $6.5 million, are not being amortized. Costs aggregating
$204.9 million and $186.9 million at December 31, 1996 and 1995, respectively,
relating to acquisitions since November 1, 1970, are being amortized on a
straight-line basis over a 40-year period. Amortization amounted to $4.9
million, $4.4 million and $3.3 million in 1996, 1995 and 1994, respectively.
Accumulated amortization of excess cost was $29.6 million and $24.7 million at
December 31, 1996 and 1995, respectively. Included in excess cost is
approximately $143 million and $142 million at December 31, 1996 and 1995,
respectively, of goodwill which resulted from various acquisitions structured to
be tax-free.
 
    Other investments consist of the following:

    The equity method of accounting is followed for minority telephone and
paging interests in which TDS holds common stock ownership of at least 20% or
can influence the policies of the affiliated company. At December 31, 1996, the
cumulative share of income from minority telephone and paging investments
accounted for under the equity method was $4.1 million, of which $2.2 million
was undistributed.
 
    The Company's investment in debt securities with original maturities of more
than 12 months are classified as marketable non-equity securities and
held-to-maturity. They are stated at amortized cost.

    The noncurrent investments have contractual maturities of more than one to

    REVENUE RECOGNITION
 
    TDS's revenues are recognized when earned. Telephone network access and
long-distance services are furnished jointly with other companies, primarily
AT&T and the Bell Operating Companies. Compensation for interstate access
services is based on tariffed access charges to interstate long-distance
carriers as filed by the National Exchange Carrier Association with the FCC on
behalf of TDS. Such compensation amounted to 32%, 33% and 31% of telephone
revenues in 1996, 1995 and 1994, respectively. Compensation for intrastate toll
and access services is based on tariffed access charges, cost separation
studies, nationwide average schedules or special settlement arrangements with
intrastate long-distance carriers. Network access and long-distance revenues
based on cost separation studies represent estimates pending completion and
acceptance of final cost studies. Management believes that recorded amounts
represent reasonable estimates of the final amounts.
 
    ADVERTISING COSTS
 
    The Company expenses advertising costs as incurred. Advertising costs
totaled $29.8 million, $17.2 million and $13.7 million for the years ended
December 31, 1996, 1995 and 1994, respectively.
 
    EARNINGS PER COMMON SHARE
 
    Earnings per Common Share were computed by dividing Net Income Available to
Common, less a minority income adjustment, by the weighted average number of
Common Shares, Series A Common Shares and dilutive common equivalent shares
outstanding during the year. The minority income adjustment, $271,000 and
$411,000 in 1995 and 1994, respectively, reflects the additional minority share
of USM's income computed as if all of USM's issuable securities were
outstanding. Dilutive common stock equivalents consist of Common Shares issuable
upon conversion of dilutive series of Preferred Shares and Common Share options.
 
    Preferred dividend requirements include all dividends paid on Preferred
Shares which are not dilutive common stock equivalents. For the year ended
December 31, 1996, the preferred dividend requirement on all outstanding
Preferred Shares was $1.8 million.

</TABLE>
 
    The increase in the 1996 effective tax rate reflects additional income tax
expense due to tax gains in excess of book gains associated with the sale of
certain cellular interests. The lower 1994 rate reflects deferred income taxes
provided on the book/tax basis difference related to certain telephone
acquisitions and certain income excluded due to the dividend exclusion rules.
 
    The total income tax expense for the year ended December 31, 1994, including
the cumulative effect of an accounting change was $40.3 million. The effective
income tax rate including the cumulative effect of an accounting change was
40.3% in 1994.
 
    Deferred income taxes are provided for the temporary differences between the
amount of the Company's assets and liabilities for financial reporting purposes
and their tax bases.
 
    The Company's current net deferred tax assets totaled $2.7 million and $3.2
million as of December 31, 1996 and 1995, respectively. The net current deferred
tax asset primarily represents the deferred tax effects of unearned revenues.

</TABLE>
 
    At December 31, 1996, TDS had $10.4 million of federal alternative minimum
tax credit carryforward available to offset regular income tax payable in future
years. In addition, TDS had $267.7 million of state net operating loss
carryforward at December 31, 1996, expiring between 1996 and 2010, which
generated a $17.1 million deferred tax asset. A valuation allowance was
established for the state operating loss carryforwards since it is more likely
than not that a portion will expire before such carryforwards can be utilized.
 
    TDS's telephone subsidiaries have recorded additional deferred income tax
liabilities related primarily to temporary differences not deferred under
rate-making policy. A corresponding regulatory asset or liability has been
established to offset these deferred income tax adjustments. The unamortized
regulated asset and liability balances are $4.3 million and $4.5 million,
respectively, as of December 31, 1996, and $5.0 million and $5.8 million,
respectively, as of December 31, 1995. These amounts are being amortized over
the lives of the related temporary differences.

    PROPERTY, PLANT AND EQUIPMENT
 
    Property, plant and equipment is stated at cost.
 
    Telephone plant in service and under construction is stated at the original
cost of construction including the capitalized costs of certain taxes,
payroll-related expenses, and an allowance for funds used during construction
("AFUDC"). The composite weighted average AFUDC rates were 7.3%, 9.3% and 10.4%
in 1996, 1995 and 1994, respectively.

    Renewals and betterments of units of property are added to telephone plant
in service. The original cost of depreciable property retired is removed from
plant in service and, together with removal cost less any salvage realized, is
charged to accumulated depreciation. Repairs and renewals of minor items of
property are included in plant operations expense. No gain or loss is recognized
on ordinary retirements of depreciable telephone property.
 
    AERL capitalizes interest ($1.2 million in 1996) on certain work in process
expenditures. When the assets are placed in service, they will be depreciated
over their respective useful lives.
 
    Certain costs relating to the development of computer software for internal
use are capitalized and are amortized over the estimated five-year life of the
software.
 
    Depreciation is provided for book purposes using the straight-line method.
Composite depreciation rates, as applied to the average cost of depreciable
property, are as follows:

    SALES OF CELLULAR AND OTHER INVESTMENTS
 
    The $138.7 million gain in 1996 reflects the sales of non-strategic cellular
and other investments. USM sold its majority interests in eight markets and
minority interests in two other markets, received cash from the settlement of
two separate legal matters and received cash in an exchange of markets with
another cellular operator. AERL sold its majority interests in two markets.
These transactions, along with the sales of certain other investments by TDS,
generated net cash proceeds of $221.5 million.
 
    The $86.6 million gain in 1995 reflects the sales and exchanges of
non-strategic cellular and other investments. USM sold its majority interests in
six markets and its minority interests in six markets during 1995. These sales,
along with the sales of marketable equity securities and certain other
investments by TDS, generated net cash proceeds of $197.6 million.
 
    The $7.5 million gain in 1994 reflects the sale and exchange of
minority-owned cellular and telephone interests. The cellular gain represents
the excess of the fair market value of the cellular interests traded over the
book value of such interests. The Company also sold its minority interest in a
telephone company for preferred shares of the telephone company having a face
value of $5.9 million and $6.0 million in cash.

    NOTES PAYABLE
 
    TDS has used short-term debt to finance its investments in PCS, cellular
telephone and radio paging operations, for acquisitions, and for general
corporate purposes. Long-term debt and equity financing from time to time have
retired such short-term debt. Proceeds from an AERL initial public offering
retired $131.2 million of short-term debt in 1996. (See Note 7-Sale of Stock by
Subsidiaries.) Proceeds from the sales of non-strategic cellular and other
investments from time to time in 1996 and 1995 have been used to retire
short-term debt. Proceeds from a USM convertible debt offering retired $131.4
million of short-term debt in 1995. Proceeds from an APP initial public offering
and TDS's sales of Common Shares retired $21.2 million of short-term debt in
1994.
 
    TDS and its subsidiaries had $678.4 million of bank lines of credit for
general corporate purposes at December 31, 1996, $653.4 million of which were
committed. Unused amounts of such lines totaled $521.0 million, $496.0 million
of which were committed. These line-of-credit agreements provide for borrowings
at negotiated rates up to the prime rate.

    SALE OF STOCK BY SUBSIDIARIES
 
    USM issued Common Shares during 1996, 1995 and 1994 in connection with
acquisitions and employee stock purchase plans. AERL issued 12.3 million Common
Shares in an initial public offering (at a price of $17 per share) in 1996. The
initial public offering reduced TDS's ownership percentage from 100% to 82.8%.
APP issued Common Shares during 1996 and 1995 in connection with employee stock
purchase plans, and in 1994 issued 3.5 million Common Shares in an initial
public offering (at a price of $14 per share). The initial public offering
reduced TDS's ownership percentage from 100% to 82.5%. The USM, AERL and APP
Common Share transactions were recorded at fair market values which were either
less than or in excess of TDS's book value investment in USM, AERL and APP. TDS
adjusted its book value investment as a result of these issues and increased
capital in excess of par value $123.2 million, $714,000 and $21.2 million in
1996, 1995 and 1994, respectively.

issue under the Automatic Dividend Reinvestment and Stock Purchase Plan and
192,254 Series A Common Shares for issue under the Series A Common Share
Automatic Dividend Reinvestment Plan. These plans enable holders of TDS's Common
Shares and Preferred Shares to reinvest cash dividends in newly issued Common
Shares and holders of Series A Common Shares to reinvest cash dividends in newly
issued Series A Common Shares. The purchase price of the shares is 95% of the

employees. The options are exercisable over a specified period not in excess of
ten years. The options expire from 1997 to 2006 or the date of the employee's
termination of employment, if earlier.

employee stock purchase plans under Accounting Principles Board ("APB") Opinion
No. 25. No compensation costs have been recognized for the stock option and
employee stock purchase plans. Compensation expense for SARS, measured on the
difference between the year-end market price of the Common Shares and SAR
prices, was $263,000, $408,000 and $218,000 in 1996, 1995 and 1994,

    COMMON SHARE REPURCHASE PROGRAM
 
    In December 1996, the Company authorized the repurchase of up to 3.0 million
TDS Common Shares over a period of three years. The Company plans to finance the
repurchase program using internally generated funds and borrowings under
short-term lines of credit. The Company may use repurchased shares to fund
acquisitions and for general corporate purposes. Subject to prevailing market
conditions, purchases may be made from time to time through open market
purchases or at negotiated prices in private transactions. The actual number of
Common Shares which may be repurchased will be subject to the trading price of
the Common Shares, the Company's financial position and other factors.

    COMMITMENTS AND CONTINGENCIES
     CONSTRUCTION AND EXPANSION
 
    The primary purpose of TDS's construction and expansion program is to
provide for normal growth, to upgrade telephone service, to expand into new
communication areas, and to take advantage of service-enhancing and
cost-reducing technological developments. The cellular capital additions budget
totals approximately $300 million for 1997, including about $258 million for new
cell sites and $30 million for various information systems initiatives. The
telephone capital additions budget totals approximately $130 million for 1997,
including about $56 million for new digital switches and other switching
facilities and $56 million for improvements to outside plant facilities. The PCS
capital additions budget totals approximately $345 million

transmitters and $16 million for pagers.
 
    PENDING ACQUISITIONS
 
    At December 31, 1996, TDS has entered into definitive agreements to acquire
a controlling interest in one cellular market and one telephone company for an
aggregate consideration of approximately $39.8 million, primarily cash and TDS
Common Shares.
 
    LEASE COMMITMENTS
 
    TDS and its subsidiaries have leases for certain cellular plant facilities,
office space and data processing equipment, most of which are classified as
operating leases. For the years 1996, 1995 and 1994, rent expense for term
leases was $20.9 million, $13.6 million and $10.4 million, respectively, and
rent expense under cancelable and short-term leases was $7.6 million, $7.5
million and $6.5 million, respectively. At December 31, 1996, the aggregate
minimum rental commitments under noncancelable operating leases were as follows:

    LEGAL PROCEEDINGS
 
    The Company is involved in a number of legal proceedings before the FCC and
various state and federal courts. In some cases, the litigation involves
disputes regarding rights to certain cellular telephone systems and other
interests. Management does not believe that any of such proceedings should have
a material adverse impact on the financial position or results of operations of
the Company.

    RESTRICTION ON COMMON STOCK DIVIDENDS
 
    Under TDS's loan agreements at December 31, 1996, all of the consolidated
retained earnings were available for the payment of cash dividends on shares of
TDS common stock.
 
    Certain regulated telephone subsidiaries may not transfer funds to the
parent in the form of cash dividends, loans or advances until certain financial
requirements of their mortgages have been met. All of the $326.6 million
underlying retained earnings of all TDS subsidiaries at December 31, 1996, was
available for the payment of dividends on the subsidiaries common stock. Of the
$2.7 billion underlying net assets of the TDS subsidiaries at December 31, 1996,

    EMPLOYEE BENEFIT PLANS
 
    PENSION PLAN
 
    The Company sponsors two qualified noncontributory defined contribution
pension plans. One plan (the "TDS Plan") provides benefits for the employees of
TDS, TDS Telecom and substantially all of the telephone company subsidiaries.
(Employees of certain telephone subsidiaries are covered under other pension
plans or receive direct pension payments.) The other plan provides pension
benefits for USM and AERL employees. Under these plans, pension costs are
calculated separately for each participant and are funded currently. TDS also
sponsors an unfunded non-qualified deferred compensation plan to supplement the
benefits under these plans to offset the reduction of benefits caused by the
limitation on annual employee compensation under the tax laws.
 
    Total pension costs were $4.6 million, $4.6 million and $4.8 million in
1996, 1995 and 1994, respectively.

medical benefits and the other plan provides life insurance benefits. Both plans
are contributory, with retiree contributions adjusted annually. The medical plan
anticipates future cost sharing changes that are consistent with the Company's
intent to increase retiree contributions by the health care cost trend rate. An
amount not to exceed 25% of the total contribution to the TDS Plan will be
contributed to fund the cost of the medical benefits annually. An additional
contribution equal to a reasonable amortization of the past service cost may be
made without regard to the 25% limitation described above. The Company will
limit overall contributions to the aggregate accruals recorded by its
subsidiaries. The Company's postretirement medical and life insurance plans are
currently underfunded. Total contributions to fund postretirement medical and
life insurance plans were $2.2 million, $3.1 million and $1.1 million in 1996,
1995 and 1994, respectively.
 
    The following table sets forth the plans' funded status reconciled with the
amount shown in the Company's consolidated balance sheet at December 31, 1996:

    For measurement purposes, a 10.2% annual rate of increase in the per capita
cost of covered health care benefits was assumed for 1996; the rate was assumed
to decrease over seven years to 6.1% and to remain at 6.1% thereafter. The
assumed rates of compensation increases and return on plan assets were 5.0% and
8.0%, respectively. The health care cost trend rate assumption has a significant
effect on the amounts reported. Increasing the assumed health care cost trend
rates by one percentage point in each year would

NOTE 15
 
    FAIR VALUES OF FINANCIAL INSTRUMENTS
 
    The carrying amounts of Cash and Cash Equivalents, Temporary Investments and
Short-term Debt approximate fair value due to the short-term nature of these
instruments.
 
    The carrying value and estimated fair value of the Company's long-term debt
was $1.0 billion and $969.5 million, respectively, at December 31, 1996, and
$894.6 million and $932.6 million, respectively, at December 31, 1995. The fair
value was estimated using discounted cash flow analysis based on the Company's
current incremental borrowing rates for similar types of borrowing arrangements.
The decrease in estimated fair value in 1996 was due to a change in the
incremental borrowing rate related to RUS, RTB and FFB Mortgage Notes.
 
    At December 31, 1996 and 1995, the carrying value of the Company's
Redeemable Preferred Shares, $1.9 million, and $15.1 million, respectively, was
approximately equal to its fair value. The fair value was estimated using
discounted cash flow analysis based on the Company's current dividend yield on
issues of its non-convertible preferred shares and, for convertible series, the
net present value of the common stock to be issued upon conversion (valued at
quoted market prices).
 
    It was not practicable to estimate the fair value of the Company's cost
method investments in other companies because of the lack of quoted market
prices. The carrying amounts at December 31, 1996 and 1995 represent the
original cost of the investments, which management believes is not impaired.

    SUBSEQUENT EVENT
 
    Exchange of Markets with Another Cellular Operator. In February 1997, USM
entered into an exchange agreement with BellSouth Corporation pursuant to which
USM will receive controlling interests in twelve contiguous markets adjacent to
its Iowa and Wisconsin/Illinois clusters. In exchange, USM will divest its
controlling interests in ten markets and investment interests in 13 markets and
cash. USM will receive controlling interests representing approximately 3.9
million pops in the transaction, and will divest controlling interests
representing approximately 1.9 million pops and investment interests
representing approximately 1.4 million pops. The transaction is subject to
various regulatory and other approvals.
 
    STANDBY LETTER OF CREDIT
 
    The Company has entered into a standby letter of credit agreement effective
July 20, 1994 with a financial institution. This standby letter of credit, which
will not exceed $9.0 million, provides supplemental security in support of a
bank loan to an entity minority-owned by the Company. In the event of default
under the minority-owned entity's bank loan agreement, the bank may call upon
the Company's standby letter of credit to satisfy any amounts still due under
this loan agreement.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
TO THE STOCKHOLDERS AND BOARD OF DIRECTORS
 
OF TELEPHONE AND DATA SYSTEMS, INC.:
 
    We have audited the accompanying consolidated balance sheets of Telephone
and Data Systems, Inc. (an Iowa corporation) and Subsidiaries as of December 31,
1996 and 1995, and the related consolidated statements of income, common
stockholders' equity, and cash flows for each of the three years in the period
ended December 31, 1996. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Telephone and Data Systems,
Inc. and Subsidiaries as of December 31, 1996 and 1995, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1996, in conformity with generally accepted accounting principles.

Note: Certain 1996 quarterly amounts were reclassified for current period
presentation.
 
Net Income Available to Common for 1996 and 1995 included significant gains from
the sales of cellular and other investments. The table above summarizes the
effect of the gains on Net Income Available to Common and Earnings per Common
Share.
 
Management believes there exists a seasonality at USM in both service revenues,
which tend to increase more slowly in the first and fourth quarters, and
operating expenses, which tend to be higher in the fourth quarter due to
increased marketing activities and customer growth. This seasonality may cause
operating income to vary from quarter to quarter.
 
In the first part of 1997, AERL is expected to begin commercial service which
will result in AERL's revenue and expenses being included in operating income.
Operating income is expected to decrease significantly in 1997 as a result of
the commencement of PCS operations.
