    4.  To transact such other business as may properly come before the meeting
       or any adjournments thereof.
 
    This Notice of Annual Meeting and Proxy Statement is first being mailed to

close of business on March 26, 1999, as the record date for the determination of
shareholders entitled to notice of, and to vote at, the Annual Meeting or any
adjournments thereof.
 
    The Board of Directors would like to have all shareholders represented at
the Annual Meeting. If you do not expect to be present, please sign and mail
your proxy in the enclosed self-addressed envelope to Harris Trust and Savings
Bank, 311 West Monroe Street, Chicago, Illinois 60606. Proxies given pursuant to
this solicitation may be revoked at any time prior to the closing of polls at
the Annual Meeting (by written notice to the Secretary of the Company or
attendance at the Annual Meeting of Shareholders and notice to the Secretary of
such revocation). Once the polls are closed, however, proxies may not be
retroactively revoked.
 
    If you hold more than one class of the Company's shares, you will find
enclosed a separate proxy card for each holding. To assure that all of your
shares are represented, please return a proxy printed in black ink for Common
Shares, including Common Shares owned through the TDS dividend reinvestment plan
and through the TDS Tax-Deferred Savings Plan; a proxy card printed in green ink
for Series A Common Shares, including Series A Common Shares owned through the
dividend reinvestment plan; a proxy card printed in red ink for Preferred Shares
issued before October 31, 1981 (Series A, B, D, G, H and N); and a proxy card
printed in blue ink for Preferred Shares issued after October 31, 1981 (Series
O, S, U, DD, EE, GG, II, JJ, KK, LL, QQ, SS and TT).
 
    On March 26, 1999, the Company had outstanding and entitled to vote
54,423,142 Common Shares, par value $.01 per share (excluding 619,083 Common
Shares held by the Company and 484,012 Common Shares held by a subsidiary of the
Company); 6,949,904 Series A Common Shares, par value $.01 per share; and
240,286 Preferred Shares, par value $.01 per share. Except as set forth in the
next paragraph, each of the outstanding Common Shares and Preferred Shares is
entitled to one vote on all matters to come before the Annual Meeting and each
of the outstanding Series A Common Shares is entitled to ten votes on all
matters to come before the Annual Meeting. Accordingly, the voting power of all
outstanding Series A Common Shares was 69,499,040 votes, and the total voting
power of all outstanding shares of all classes of capital stock was 124,162,468
votes at March 26, 1999.
 
    With respect to the election of directors at the Annual Meeting, the holders
of Common Shares and holders of the Preferred Shares issued before October 31,
1981 (Series A, B, D, G, H and N), voting as a group (collectively, the "Common
Holders"), will be entitled to elect one Class III director. The holders of
Series A Common Shares and the holders of the Preferred Shares issued after
October 31, 1981 (Series O, S, U, DD, EE, GG, II, JJ, KK, LL, QQ, SS and TT),
voting as a group (collectively, the "Series A Holders"), will be entitled to
elect two Class I directors and three Class III directors. The Voting Trust
under Agreement dated June 30, 1989, as amended, (the "TDS Voting Trust") holds
6,351,116 Series A Common Shares, representing approximately 91.4% of the Series
A Common Shares. By
<PAGE>
reason of such holding, the TDS Voting Trust has the voting power to elect all
of the directors elected by the Series A Holders of the Company and has
approximately 51.2% of the voting power with respect to matters other than the
election of directors. The TDS Voting Trust as a Series A Holder will elect two
Class I directors and three Class III directors at the Annual Meeting. The TDS
Voting Trust has advised the Company that it intends to vote FOR the Company's
nominees for election as Class I directors and Class III directors and FOR each
of the other proposals.
 
                               VOTING INFORMATION
 
    The Common Holders may, with respect to the election of the Class III
director to be elected by the Common Holders, vote FOR the election of such
director nominee or WITHHOLD authority to vote for such director nominee. The
Series A Holders may, with respect to the election of the Class I directors and
the Class III directors to be elected by the Series A Holders, vote FOR the
election of such director nominees or WITHHOLD authority to vote for such
director nominees. A shareholder may, with respect to the proposal to approve
the 1999 Employee Stock Purchase Plan, (i) vote FOR approval, (ii) vote AGAINST
approval, or (III) ABSTAIN from voting on the proposal. A shareholder may, with
respect to the proposal to ratify the selection of Arthur Andersen LLP as the
Company's independent public accountants for 1999, (i) vote FOR approval, (ii)
vote AGAINST approval or (iii) ABSTAIN from voting on such proposal. The Board
of Directors recommends a vote FOR the Board of Director's nominees for Class I
and Class III directors, FOR the approval of the 1999 Employee Stock Purchase
Plan and FOR the ratification of the selection of Arthur Andersen LLP. All
properly executed and unrevoked proxies received in the accompanying form in
time for the 1999 Annual Meeting of Shareholders will be voted in the manner
directed therein. If no direction is made, a proxy by any shareholder will be
voted FOR the election of the Board of Director's nominees to serve as Class I
and Class III directors, FOR the approval of the 1999 Employee Stock Purchase
Plan and FOR the proposal to ratify the selection of Arthur Andersen LLP as the
Company's independent public accountants for 1999.
 
    The election of the Class III director to be elected by the Common Holders
requires the affirmative vote of holders of a plurality of the votes of the
shares present in person or represented by proxy and entitled to vote with
respect to such director at the Annual Meeting. Accordingly, if a quorum exists,
the person receiving a plurality of the votes of the Common Holders with respect
to the election of such Class III director will be elected to serve as a Class
III director. A majority of the votes entitled to be cast with respect to the
election of such Class III director by such voting group constitutes a quorum
for action on such proposal. Withheld votes and non-votes with respect to the
election of such Class III director will not affect the outcome of the election
of such director.
 
    The election of the Class I directors and Class III directors to be elected
by the Series A Holders requires the affirmative vote of holders of a plurality
of the votes of the shares present in person or represented by proxy and
entitled to vote with respect to such directors at the Annual Meeting.
Accordingly, if a quorum exists, each person receiving a plurality of the votes
of the Series A Holders with respect to the election of such Class I director
and each Class III director will be elected to serve as a Class I director or
Class III director, respectively. A majority of the votes entitled to be cast
with respect to the election of such Class I or Class III directors by such
voting group constitutes a quorum for action on such proposal. Withheld and
non-votes with respect to the election of such Class I or Class III directors
will not affect the outcome of the election of such Class I or Class III
directors.
 
    If a quorum is present at the Annual Meeting, the proposal to approve the
1999 Employee Stock Purchase Plan requires the affirmative vote of a majority of
the voting power of all shares of capital stock of the Company voting together
and present in person or represented by proxy and entitled to vote on such
matter at the Annual Meeting. A vote to abstain from voting on such proposal
will be treated as a vote against such proposal. Non-votes with respect to such
proposal will not affect the determination of whether such proposal is approved.
 
    Assuming a quorum exists, the approval of the proposal to ratify the
selection of Arthur Andersen LLP as the Company's independent public accountants
for 1999 requires that the affirmative vote of a majority of the voting power of
all shares of capital stock of the Company present in person or represented by
proxy and entitled to vote with respect to such matter. A majority of the votes
entitled to be cast on the proposal constitutes a quorum for action on that
proposal. Abstentions will be treated as votes against this proposal. Non-votes
will not affect the determination of whether such proposal is approved for
purposes of such vote.
 
    A complete list of shareholders entitled to vote at the Annual Meeting,
arranged in alphabetical order and by voting group, showing the address of and
number of shares held by each shareholder, will be kept open at the offices of
the Company, 30 North LaSalle Street, 40th Floor, Chicago, Illinois 60602, for
examination by any shareholder during normal business hours, for a period of at
least ten days prior to the Annual Meeting.

COMMITTEES AND MEETINGS
 
    The Board of Directors of the Company held 13 meetings during 1998. Each
person who was a director during all of 1998 attended at least 75% of the
meetings.
 
    The Board of Directors does not have a formal nominating committee.
 
    The Audit Committee of the Board of Directors, among other things,
determines audit policies, reviews external and internal audit reports and
reviews recommendations made by the Company's internal auditing staff and
independent public accountants. The current members of the Audit Committee are:
Messrs. Walter C. D. Carlson (Chairman), George W. Off and Herbert S. Wander.
The Audit Committee held 4 meetings in 1998. Each person who was a member of the
Audit Committee during 1998 attended at least 75% of the meetings.
 
    The Stock Option Compensation Committee approves the annual salary, bonus
and other cash compensation for the President, considers and approves long-term
compensation for executive officers and considers and recommends to the Board of
Directors any changes to long-term compensation plans or policies. The current
members of the Stock Option Compensation Committee are: Mr. George W. Off
(Chairman) and Dr. Letitia G. C. Carlson. All meetings and other actions of the
Stock Option Compensation Committee in 1998 were attended or taken by at least
75% of the members.
 
                                      -5-
<PAGE>
    The primary function of the Compensation Committee is to approve the annual
salary, bonus and other cash compensation of officers and key employees of TDS
other than the President. The sole member of the Compensation Committee is LeRoy
T. Carlson, Jr., President of TDS. All actions of the Compensation Committee are
taken by written consent.
 
    In late 1998, the Board of Directors established a Special Committee
consisting of all directors of TDS other than Mr. Murray L. Swanson (the
"Special Committee"). The Special Committee was authorized to consider various
alternatives with respect to TDS's investment in Aerial, including a spin-off of
Aerial, and to make its recommendation to the TDS Board of Directors. The TDS
Board of Directors believed that the consideration of such alternatives may
involve confidential and privileged information relating to TDS's investment in
Aerial, which might involve a conflict of interest with Sonera Ltd. Since Mr.
Swanson is the Managing Director and CEO of Sonera Corporation U.S., a
subsidiary of Sonera Ltd, the Board of Directors determined that it would be
desirable to establish a committee consisting of all directors other than Mr.
Swanson to consider such alternatives. The Special Committee held two meetings
in 1998. All of the members of the Special Committee attended at least 75% of
the meetings held in 1998.
 
                                   PROPOSAL 2
                       1999 EMPLOYEE STOCK PURCHASE PLAN
 
    The Board of Directors has determined that it is in the best interests of
the Company and its shareholders to approve the 1999 Employee Stock Purchase
Plan of the Company (the "Plan").
 
    The purpose of the Plan is to encourage and facilitate the purchase of
Common Shares by eligible employees of the Company and its subsidiaries and to
provide an additional incentive to promote the best interests of the Company and
its subsidiaries and an additional opportunity to participate in their economic
progress. The Plan was adopted by the Board of Directors of the Company (the
"Board") and will become effective July 1, 1999. The Plan is subject to the
approval of the shareholders of the Company within twelve months before or after
its adoption by the Board. The Plan will be administered by a three-person
committee (the "Committee") composed of persons who are ineligible to
participate in the Plan. Subject to the express provisions of the Plan, the
Committee will have complete authority to interpret the Plan, to prescribe,
amend and rescind rules and regulations relating to it and to make all other
determinations necessary or advisable for the administration of the Plan. The
Board may at any time, and from time to time, amend the Plan in any respect,
except that, without shareholder approval, no amendment may be made changing the
number of shares to be reserved under the Plan (unless certain changes occur in
the Company's capital structure as described in the Plan), or that would
otherwise require shareholder approval under applicable law.
 
    The Plan will terminate on December 31, 2002 (the "Termination Date"), or,
if earlier, upon the purchase by participants of all shares that may be issued
under the Plan or any earlier time in the discretion of the Board. The Plan is
comprised of two "Offering Periods," the first of which is an 18-month period
beginning on July 1, 1999 and ending on December 31, 2000, and the second of
which is a 24-month period beginning on January 1, 2001 and ending on December
31, 2002. Each Offering Period is comprised of consecutive quarterly "Purchase
Periods," the last day of each of which is a "Purchase Date." In addition, the
date on which the Plan terminates will be treated as a "Purchase Date" under the
Plan and the last day of an "Offering Period."
 
    In general, participation in the Plan is available to any Eligible Employee
(as hereinafter defined) of the Company or any of its subsidiaries that has
adopted the Plan with the prior approval of the Company (a "participating
subsidiary"). For purposes of the preceding sentence, an "Eligible Employee" is
any employee of the Company or a participating subsidiary, other than a leased
employee (within the meaning of section 414(n) of the Code). Each Eligible
Employee can enroll in the Plan as of the first entry date as of which the
Eligible Employee completes the Plan's eligibility service requirement, or can
enroll as of any later date. The Plan's eligibility service requirement is
satisfied if an employee completes at least three months of continuous service
with the Company or any subsidiary thereof (regardless of whether the subsidiary
is a participating subsidiary). Under the Plan, an entry date occurs on July 1,
1999 and the first day of each subsequent calendar month. Upon enrollment, an
Eligible Employee will become a "Participant" in the Plan. Approximately 9,000
employees will be eligible to participate in the Plan as of January 1, 1999.
 
    For each Offering Period, each Eligible Employee will be granted an option
under the Plan, as of the first day of the Offering Period, or if later, the
first entry date on which the Eligible Employee is eligible to enroll in the
Plan (a "grant date"), to purchase a number of Common Shares equal to (x)
$25,000, multiplied by (y) the number of full or partial calendar years in the
Offering Period (as hereinafter defined), divided by (z) the closing price of a
Common
 
                                      -6-
<PAGE>
Share on the American Stock Exchange on the grant date (or if such date is not a
trading day, the closing price of such share on the American Stock Exchange on
the next preceding trading day). However, no Eligible Employee will be granted
an option under the Plan to purchase Common Shares if such Eligible Employee,
immediately after the grant of the option, would own stock (including shares
subject to the option) possessing five percent or more of the total combined
voting power or value of all classes of issued and outstanding stock of the
Company or any of its subsidiaries.
 
    The maximum number of shares available for purchase under the Plan will be
210,000, subject to adjustment in the event of certain changes to the Company's
capital structure, as described in the Plan.
 
    As of the entry date on which an Eligible Employee enrolls as a Participant
in the Plan, the Participant will make an election specifying his chosen rate of
payroll deduction contributions in an amount not less than one and not more than
15 percent of the Participant's compensation (as defined in the Plan) for each
payroll period, effective as soon as administratively practicable after such
election is made. A Participant will have the right to elect to increase or
decrease his or her designated rate of payroll deductions under the Plan from
time to time, in the manner prescribed by the Committee. In addition, a
Participant can elect to withdraw from participation in the Plan for the
remainder of an Offering Period, as described below.
 
    The Committee will cause to be established a separate "Employee Stock
Purchase Account" on behalf of each Participant to hold payroll deduction
contributions made under the Plan. Subject to a Participant's right to withdraw
for an Offering Period as described below, the balance of each Participant's
Employee Stock Purchase Account will be applied on each Purchase Date to
purchase the number of Common Shares determined by dividing the balance of such
account as of such date by the Purchase Price of a Common Share on such date.
The "Purchase Price" under the Plan on a Purchase Date is 85 percent of the
closing price of a Common Share on the American Stock Exchange on such date, or
if such date is not a trading day, 85 percent of the closing price of a Common
Share on the next preceding trading day, rounded up to the nearest whole cent.
The number of Common Shares to be purchased on a Purchase Date will be rounded
to the nearest one ten-thousandth of a share (or such other fractional interest
determined by the Committee).
 
    Notwithstanding the foregoing, the number of Common Shares to be purchased
by a Participant on a Purchase Date will be limited to the extent necessary so
that the Participant's right to purchase Common Shares under the Plan and shares
under all other employee stock purchase plans maintained by the Company or any
of its subsidiaries does not accrue at a rate exceeding $25,000 of the fair
market value of such shares (determined at the time such option is granted) for
each calendar year in which the option is outstanding, determined in accordance
with section 423(b)(8) of the Code. If any portion of a Participant's Employee
Stock Purchase Account cannot be applied to purchase Common Shares on a Purchase
Date as a result of this limitation, such amount will remain credited to such
account and will be available to purchase Common Shares as of the next Purchase
Date; provided that, if such Purchase Date is on the last day of an Offering
Period, the balance of such account will promptly be refunded to the
Participant.
 
    If, as of a Purchase Date, the number of Common Shares to be purchased on
behalf of all Participants collectively exceeds the number of Common Shares
available for purchase under the Plan, the number of Common Shares to be
purchased by each Participant on the Purchase Date will be proportionately
reduced in the manner described in the Plan. Amounts credited to a Participant's
Employee Stock Purchase Account that are not applied to purchase Common Shares
as a result of this limitation will promptly be refunded to the Participant.
 
    A Stock Account will be established on behalf of each Participant in the
Plan by a custodian selected by the Company. As of each Purchase Date, each
Participant's Stock Account will be credited with the number of whole and
fractional shares purchased on the Participant's behalf under the Plan on such
date. Shares credited to a Participant's Stock Account will be held by the
custodian as nominee. The custodian will establish procedures pursuant to which
a Participant can elect that shares credited to such account be registered in
the name of the Participant (or jointly in the name of a Participant and one
other person), and that certificates representing such shares be issued to the
Participant.
 
    Prior to the end of any Offering Period, a Participant can elect to withdraw
from the Plan for the remainder of the Offering Period. A Participant's election
to withdraw for an Offering Period will be made in the time and manner
prescribed by the Committee. Upon withdrawal from the Plan, the balance of the
Participant's Employee Stock Purchase Account promptly will be refunded to the
Participant. A Participant who withdraws for an Offering Period will not be
eligible to elect to recommence participation in the Plan until the next
Offering Period.
 
                                      -7-
<PAGE>
    In the event of a Participant's termination of employment on account of
retirement or death, the balance of the Participant's Employee Stock Purchase
Account will be applied to purchase Common Shares on the next Purchase Date
unless the Participant (or the Participant's estate) elects to withdraw from the
Plan in the time and manner prescribed by the Committee. In the event of the
termination of the Participant's employment for any other reason, the
Participant's participation in the Plan will cease, and the balance of the
Participant's Employee Stock Purchase Account promptly will be refunded to the
Participant. Special rules apply in the event a Participant's employment is
transferred from the Company or a participating subsidiary to a
non-participating subsidiary.
 
    The Company believes that the Plan qualifies under section 423 of the Code
as an employee stock purchase plan. Under section 423 the Participant does not
recognize any taxable income at the time Common Shares are purchased under the
Plan. The following is a brief summary of the federal income tax consequences
under the Plan.
 
    If a Participant disposes of Common Shares purchased under the Plan within
two years of the grant date (as defined above) or within one year after an
applicable Purchase Date, whichever is later (a "disqualifying disposition"),
the Participant will recognize ordinary compensation income in the amount of the
excess of the fair market value of the Common Shares on such Purchase Date over
the Purchase Price of the shares. The Participant's cost basis in the shares
will be increased by the amount of such ordinary compensation income. If the
amount realized upon such disposition exceeds the Participant's cost basis in
the shares (as so increased), the Participant will recognize capital gain in the
amount of the difference between the amount realized and such adjusted cost
basis. Under current tax law, gain on capital assets held for 12 months or less
is treated as "short-term" capital gain which is not eligible for certain
preferential tax treatment afforded "long-term" capital gain. In the event the
amount realized is less than the cost basis in the Common Shares (as so
increased), the Participant will recognize capital loss in the amount of the
difference between the adjusted cost basis and the amount realized.
 
    If a Participant disposes of Common Shares purchased under the Plan two
years or more after the grant date or one year or more after the applicable
Purchase Date, whichever is later (a "qualifying disposition"), the tax
treatment will be different. The Participant will recognize ordinary
compensation income in the amount of the lesser of (i) the excess of the fair
market value of the Common Shares on the grant date over the option price of the
shares (in this case, 85 percent of the closing price for such shares on the
American Stock Exchange) on the grant date, and (ii) the excess of the amount
realized over the Purchase Price of the Common Shares. The Participant's cost
basis in the shares will be increased by the amount of such ordinary
compensation income. In addition, the Participant will recognize capital gain
equal to the difference (if any) between the amount realized upon such
disposition and the cost basis in the shares (as so increased). In the event the
amount realized is less than the Purchase Price, the Participant will recognize
capital loss in the amount of the difference between the Purchase Price and the
amount realized.
 
    The Company will not be entitled to a deduction for any excess of the fair
market value of the Common Shares over the Purchase Price, except to the extent
the Participant recognizes ordinary compensation income upon a disqualifying
disposition.
 
    The Company has not provided a table of new plan benefits since the benefits
to executive officers is not determinable. The benefits will depend on the
number of Common Shares which the executive officers will subscribe for, if any,
under the plan and the future price of such shares.
 
    This description of the Plan is a summary only and is qualified by the terms
of the Plan itself, a copy of which is attached to this Proxy Statement as
Exhibit A.
 
    THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" APPROVAL OF THE COMPANY'S
1999 EMPLOYEE STOCK PURCHASE PLAN.
 
                                   PROPOSAL 3
                         INDEPENDENT PUBLIC ACCOUNTANTS
 
    The Board of Directors anticipates continuing the services of Arthur
Andersen LLP as independent public accountants for the current fiscal year.
Representatives of Arthur Andersen LLP, who served as independent public
accountants for the last fiscal year, are expected to be present at the Annual
Meeting of Shareholders and will have the opportunity to make a statement and
respond to appropriate questions raised by shareholders at the Annual Meeting or
submitted in writing prior thereto.
 
    Shareholder ratification of the selection of Arthur Andersen LLP as the
Company's independent public accountants is not required by the Bylaws or
otherwise. However, as a matter of good corporate practice, the Board of
Directors has elected to seek such ratification by the affirmative vote of the
holders of a majority of the votes cast
 
                                      -8-
<PAGE>
by shares entitled to vote with respect to such matter at the Annual Meeting.
Should the shareholders fail to ratify the selection of Arthur Andersen LLP as
independent public accountants, the Board of Directors will consider whether to
retain such firm for the year ending December 31, 1999.
 
    THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" RATIFICATION OF THE SELECTION
OF ARTHUR ANDERSEN LLP AS INDEPENDENT PUBLIC ACCOUNTANTS FOR THE COMPANY FOR THE

TDS TELECOM PHANTOM INCENTIVE OPTION PLAN
 
    Mr. James Barr III participates in the TDS Telecommunications Corporation
Phantom Stock Incentive Plan (the "TDS Telecom Plan"). The TDS Telecom Plan was
adopted by TDS Telecom in 1997 and relates to the five-year
 
                                      -14-
<PAGE>
period beginning on January 1, 1995. Under the TDS Telecom Plan, Mr. Barr was
awarded certain phantom stock units by the Chairman of TDS Telecom. The award
consists of automatic awards and performance awards. The automatic awards vest
in five equal annual installments beginning on December 15, 1995. The
performance awards include a corporate performance award and an individual
performance award. The performance awards vest on December 15 of the year
following the performance year to which they relate. When vested, the phantom
stock option units may be exercised at an exercise price determined in
accordance with the terms of the plan. All phantom stock unit options expire on
July 1, 2003. Upon exercise of the phantom stock units, Mr. Barr will receive a
cash payment equal to the difference between the exercise price and the implied
value of the phantom stock unit as provided in the TDS Telecom Plan. In 1998,
Mr. Barr exercised options for an aggregate of 106,960 phantom stock units for
1995, 1996, 1997 and 1998, and received a net cash payment, prior to withholding
taxes, of $327,410. See "Summary Compensation Table."
 
    The following table summarizes the award of options for phantom stock units
to Mr. Barr in 1998:

PENSION PLANS AND SUPPLEMENTAL BENEFIT AGREEMENTS
 
    The Telephone and Data Systems, Inc. Employees' Pension Trust (the "TDS
Pension Plan") is a defined contribution plan designed to provide retirement
benefits for eligible employees of the Company and certain of its affiliates
which adopt the TDS Pension Plan. Annual employer contributions based upon
actuarial assumptions are made under a formula designed to fund a target pension
benefit for each participant commencing generally upon the participant's
attainment of retirement age. The amounts of the annual contributions are
included above in the Summary Compensation Table under "All Other Compensation."
 
    USM and AERL have adopted the Telephone and Data Systems, Inc. Wireless
Companies' Pension Plan (the "Wireless Pension Plan"). The Wireless Pension
Plan, a qualified non-contributory defined contribution pension plan, provides
pension benefits for USM and AERL employees. Under the Wireless Pension Plan,
pension costs are calculated separately for each participant and are funded
currently. The amounts of the annual contributions for Messrs. H. Donald Nelson
and Donald W. Warkentin are included above in the Summary Compensation Table
under "All Other Compensation."
 
    The TDS Supplemental Executive Retirement Plan ("SERP") provides
supplemental benefits under the TDS Pension Plan and the Wireless Pension Plan.
The SERP was established to offset the reduction of benefits caused by the
limitation on annual employee compensation under the Code. The SERP is a
non-qualified deferred compensation plan and is intended to be unfunded. The
amounts of the accruals for the benefit of the named executive officers are
included above in the Summary Compensation Table under "All Other Compensation."
 
    In 1980, TDS entered into a non-qualified supplemental benefit agreement
with LeRoy T. Carlson which, as amended, requires TDS to pay a supplemental
retirement benefit to Mr. Carlson, in the amount of $47,567 plus interest at a
rate equal to 1/4% under the prime rate for the period from May 15, 1981 (the
date of Mr. Carlson's 65th birthday) to May 31, 1992, in five annual
installments beginning June 1, 2001, plus interest at 9 1/2% compounded
semi-annually from June 1, 1992. The agreement was entered into because certain
amendments made to the TDS Pension Plan in 1974 had the effect of reducing the
amount of retirement benefits which Mr. Carlson would receive under the TDS
Pension Plan. The payments to be made under the agreement, together with the
retirement benefits under the TDS Pension Plan, were designed to permit Mr.
Carlson to receive approximately the same retirement benefits he would have
received if the TDS Pension Plan had not been amended. All of the interest
accrued under this agreement is included above in the Summary Compensation Table
under "All Other Compensation" and identified in footnote 6 thereto as
contributions under the TDS Pension Plan.
 
                                      -15-
<PAGE>
    In 1988, USM entered into a non-qualified supplemental benefit agreement
with H. Donald Nelson which requires USM to pay a supplemental retirement
benefit to Mr. Nelson. The agreement was entered into because Mr. Nelson's
employment with TDS was terminated upon the completion of the initial public
offering of USM Common Shares in 1988 and, as a result, he was no longer
eligible to participate in the TDS Pension Plan. Under the supplemental benefit
agreement, USM is obligated to pay Mr. Nelson an amount equal to the difference
between the retirement benefit he will receive from the TDS Pension Plan and
that which he would have received had he continued to work for TDS, less any
amounts which he is entitled to receive under any other qualified pension plan
(such as the Wireless Pension Plan). USM will pay any such benefit at the same
time as Mr. Nelson receives payments from the TDS Pension Plan. The actual
benefits payable to Mr. Nelson upon retirement will be based upon the facts that
exist at the time and will be determined actuarially. Since the nature of this
agreement is a defined benefit arrangement, no amounts related thereto are
included above in the Summary Compensation Table.
 
    In 1996, AERL entered into a non-qualified supplemental benefit agreement
with Donald W. Warkentin which requires AERL to pay a supplemental retirement
benefit to Mr. Warkentin. The agreement was entered into because Mr. Warkentin's
employment with TDS was terminated as a result of the completion of the initial
public offering of AERL Common Shares in 1996 and, as a result, he was no longer
eligible to participate in the TDS Pension Plan. Under the supplemental benefit
agreement, AERL is obligated to pay Mr. Warkentin an amount equal to the
difference between the retirement benefit he will receive from the TDS Pension
Plan and that which he would have received had he continued to work for TDS,
less any amounts which he is entitled to receive under any other qualified
defined benefit or money purchase pension plan (such as the Wireless Pension
Plan). AERL will pay any such benefit at the same time as Mr. Warkentin receives
payments from the TDS Pension Plan. The actual benefits payable to Mr. Warkentin
upon retirement will be based upon the facts that exist at the time and will be
determined actuarially. Since the nature of this agreement is a defined benefit
arrangement, no amounts related thereto are included above in the Summary
Compensation Table.
 
DEFERRED COMPENSATION AGREEMENTS
 
    Mr. H. Donald Nelson and Mr. James Barr III are parties to Executive
Deferred Compensation Agreements, pursuant to which such persons will have a
specified percentage of gross compensation deferred and credited to a Deferred
Compensation Account. The Deferred Compensation Account will be credited with
interest compounded monthly, computed at a rate equal to one-twelfth of the sum
of the average thirty-year Treasury Bond rate plus 1.25 percentage points until
the Deferred Compensation Amount is paid to such persons. The amount of
compensation deferred by such persons is included in and reported with all other
non-deferred compensation in the "Summary Compensation Table." No amount is
included in the Summary Compensation Table for the interest earned on such
deferred compensation since such interest rate is intended to approximate a
market rate.
 
BONUS DEFERRAL AND STOCK UNIT MATCH PROGRAM
 
    The 1998 Long-Term Incentive Plan (the "1998 Plan") provides the opportunity
for those who are employed by TDS at the position of Vice President or above, to
defer receipt of a portion of their bonuses and receive TDS matching stock unit
credits. Executives may elect to defer receipt of all or a portion of their
annual bonuses and to receive stock unit matches on the amount deferred.
Deferred compensation will be deemed invested in phantom TDS Common Shares. TDS
match amounts will depend on the amount of annual bonus that is deferred into
stock units. Participants receive a 25% stock unit match for amounts deferred
under 50% of their total annual bonus and a 33% match for amounts that exceed
50% of their total annual bonus. The matched stock units vest ratably at a rate
of one-third per year over three years. The fair market value of the matched
stock units are reported in the Summary Compensation Table under "Other Annual
Compensation."
 
    LeRoy T. Carlson and LeRoy T. Carlson, Jr., each elected to defer 100% of
their 1998 bonus under the 1998 Plan. Accordingly, each of LeRoy T. Carlson and
LeRoy T. Carlson, Jr. will receive a 25% stock unit match for 50% of their 1998
bonuses and a 33% match for 50% of their bonuses under the 1998 Plan. The
bonuses for 1998 have not yet been determined for Messrs. LeRoy T. Carlson and
LeRoy T. Carlson, Jr. and, therefore, the dollar value of the company match
phantom stock units cannot be determined at this time for such persons. See the
"Summary Compensation Table."
 
    In addition, USM has a similar plan pursuant to which H. Donald Nelson has
deferred compensation and receives stock unit matches with respect to USM Common
Shares, as reported in the Summary Compensation Table under "Other Annual
Compensation."

<PAGE>
SALARY CONTINUATION AND CONSULTING AGREEMENT
 
    The Company has entered into an agreement with LeRoy T. Carlson whereby it
will employ Mr. Carlson until he elects to retire. Mr. Carlson is to be paid at
least $60,000 per annum until his retirement. The agreement also provides that
upon his retirement, Mr. Carlson will be retained by the Company as a part-time
consultant (for not more than 60 hours in any month) until his death or
disability. Upon his retirement, Mr. Carlson will receive $75,000 per annum as a
consultant, plus increments beginning in 1985 equal to the greater of three
percent of his consulting fee or two-thirds of the percentage increase in the
consumer price index for the Chicago metropolitan area. If Mr. Carlson becomes
disabled before retiring, the Company can elect to discontinue his employment
and retain him in accordance with the consulting arrangement described above.
Upon Mr. Carlson's death (unless his death follows his voluntary termination of
his employment or the consulting arrangement), his widow will receive until her
death an amount equal to that which Mr. Carlson would have received as a
consultant. The Company may terminate payments under the agreement if Mr.
Carlson becomes the owner of more than 21% of the stock, or becomes an officer,
director, employee or paid agent of any competitor of the Company within the
continental United States. No amounts were paid or payable under this agreement
in 1998, 1997 or 1996, and no amounts related thereto are included above in the
Summary Compensation Table.
 
COMPENSATION OF DIRECTORS
 
    Effective July 23, 1996, the Board of Directors adopted a Compensation Plan
(the "Non-Employee Directors' Plan") for non-employee directors ("Non-Employee
Directors"). A Non-Employee Director is a director of the Company who is not an
employee of the Company, USM, AERL or TDS Telecom ("Affiliates"). The purpose of
the Non-Employee Directors' Plan is to provide for reasonable compensation to
non-employee directors in connection with their services to the Company, in
order to induce qualified persons to become and serve as non-employee members of
the Board of Directors.
 
    The Non-Employee Directors' Plan provides that, effective for the twelve
month period ending at the time of the Company's 1997 annual meeting, each
Non-Employee Director will receive an annual director's fee of $24,000; and each
director of the Company who is not an employee of any Affiliate will continue to
receive a fee of $1,000, plus reimbursement of reasonable out-of-pocket expenses
incurred in connection with travel, for attendance at each regularly scheduled
or special meeting of the Board of Directors. The Non-Employee Directors' Plan
also provides that, effective as of July 23, 1996, each director of the Company
who is not an employee of any Affiliate will receive a fee of $750, plus
reimbursement of reasonable out-of-pocket expenses incurred in connection with
travel, for attendance at each meeting of the Audit Committee, Stock Option
Compensation Committee, or other committee established by resolution of the
Board of Directors.
 
    Under the Non-Employee Directors' Plan, an amount equal to 50% of the annual
director's fee will be paid immediately prior to the Company's Annual Meeting of
Shareholders by the delivery of Common Shares of the Company having a fair
market value as of the date of payment equal to such percentage of the annual
fee. In addition, under the Non-Employee Directors' Plan, an amount equal to 33%
of each committee meeting fee will be accumulated and paid immediately prior to
the Company's Annual Meeting of Shareholders by the delivery of Common Shares of
the Company having a fair market value as of the date of payment equal to such
percentage of such fee. The Company has reserved 15,000 Common Shares of the
Company for issuance pursuant to the Non-Employer Director's Plan.
 
    Donald C. Nebergall, a director of the Company, also received $24,000 as a
bonus and $178,000 for consulting services provided to the Company and was
reimbursed for out-of-pocket expenses incurred in connection with such services
in 1998.
 
    In addition, the Company pays life insurance premiums on behalf of
directors. Except for such life insurance premiums, directors who are also
employees of the Company or any Affiliate do not receive any additional
compensation for services rendered as directors.
 
EXECUTIVE OFFICER COMPENSATION REPORT
 
    This report is submitted by LeRoy T. Carlson, Jr., President, who serves as
the Compensation Committee of the Board of Directors for all executive officers
of the Company other than the President, and by the TDS Stock Option
Compensation Committee of the Board of Directors, which approves all
compensation for the President and approves long-term compensation to executive
officers who are employees of the Company. Long-term compensation for H. Donald
Nelson is approved by the stock option compensation committee of USM (as
described in its
 
                                      -17-
<PAGE>
report in the proxy statement of USM), and long-term compensation for Donald W.
Warkentin is approved by the stock option compensation committee of AERL (as
described in its report in the proxy statement of AERL).
 
    The Company's compensation policies for executive officers are intended to
provide incentives for the achievement of corporate and individual performance
goals and to provide compensation consistent with the financial performance of
the Company. The Company's policies are based on the belief that the incentive
compensation performance goals for executive officers should be based on factors
over which such officers have control and which are important to the Company's
long-term success. It is also believed that compensation paid should be
appropriate in relation to the financial performance of the Company and should
be sufficient to enable the Company to attract and retain individuals possessing
the talents required for the Company's long-term successful performance.
 
    Executive compensation consists of both annual and long-term compensation.
Annual compensation consists of a base salary and an annual bonus. The Company
evaluates the annual compensation of each executive officer on an aggregate
basis by combining the base salary and bonus, and also evaluates the level of
the base salary and the bonus separately. Annual compensation decisions are
based partly on individual and corporate short-term performance and partly on
the individual and corporate cumulative long-term performance during the
executive's tenure in his position, particularly with regard to the President
(chief executive officer). Long-term compensation is intended to compensate
executives primarily for their contributions to long-term increases in
shareholder value. Long-term compensation is generally provided through the
grant of stock options.
 
    The process of determining base salary begins with establishing an
appropriate salary range for each officer. Each officer's range is based upon
the particular duties and responsibilities of the officer, as well as salaries
for comparable positions with other companies. These other companies include the
companies included in the peer group index described below under "Stock
Performance Chart", as well as other companies in the telecommunications
industry and other industries with similar characteristics, to the extent
considered appropriate in the judgment of the President, based on similar size,
function, geography or otherwise. No written or formal list of specific
companies is prepared. Instead, as discussed below, the President is provided
with various sources of information about executive compensation at other
companies, such as compensation reported in proxy statements of comparable
companies and salary surveys published by various organizations. The President
uses these sources and makes a personal determination of appropriate sources,
companies and ranges for each executive officer. The base salary of each officer
is set within a range considered appropriate in the judgment of the President
based on an assessment of the particular responsibilities and performance of
such officer, taking into account the performance of the Company and/or its
business units or divisions, other comparable companies, the industry and the
economy in general during the immediately preceding year. The President makes a
personal determination of the appropriate range based on the total mix of
information available to him. The range considered to be relevant by the
President is based on his informed judgment, using the information provided to
him by the Vice President of Human Resources, as discussed below. The range is
not based on any formal analysis nor is there any documentation of the range
which the President considers relevant in making his compensation decisions. The
salary of the executive officers is believed to be at slightly above the median
of the range considered to be relevant in the judgment of the President.
 
    Annually, the nature and extent of each executive officer's major
accomplishments and contributions for the year are determined through written
information prepared by the executive and by others familiar with his
performance, including the executive's direct supervisor. With regard to all
executive officers other than the President, the President evaluates the
information in terms of the personal objectives given by the President or other
direct supervisor to such executive officer for the performance appraisal
period. The President also makes an assessment of how well the Company did as a
whole during the year and the extent to which the President believes the
executive officer contributed to the results. With respect to executive officers
having primary responsibility over a certain business unit or division of the
Company, the President considers the performance of the business unit or
division and makes an assessment of the contribution of the executive officer
thereto. No specific measures of performance are considered determinative in the
compensation of executive officers. Instead, all of the facts and circumstances
are taken into consideration by the President in his executive compensation
decisions. Ultimately, it is the informed judgment of the President that
determines an executive's salary and bonus, this being based on the total mix of
information rather than on any specific measures of performance.
 
    The primary focus of the Company is increasing long-term shareholder value
through growth, measured primarily in such terms as revenues, customer units in
service, operating cash flow (operating income plus depreciation and
amortization) and operating income. However, there is no quantifiable or direct
relationship between compensation and such or any other measures of performance.
Instead, such compensation decisions
 
                                      -18-
<PAGE>
are made subjectively considering such performance measures, as well as all
other facts and circumstances in general terms.
 
    Other than for the President of TDS, the President of TDS approves annual
compensation for executive officers of TDS and each of its business units or
divisions. The Vice President-Human Resources accumulates and prepares various
materials, including relevant base pay and bonus information, for the annual
compensation reviews of executive officers. These materials are reviewed by the
President along with various performance evaluation information. The President
will determine the bonus for 1998 and base salary for 1999 for all executives
other than himself. The Company has no written or formal corporate bonus plan.
The bonuses for corporate executive officers are determined by the President
based on his evaluation of each executive's contribution to the Company, the
achievement of individual objectives, the performance of the Company and/or its
business units and divisions and all other facts and circumstances considered
relevant in his judgment. The President has not yet taken action to approve the
final 1998 bonuses and/or the 1999 base salaries for certain of these
executives. Due to the fact that certain 1998 bonuses had not been determined as
of the end of 1998, the President approved advance bonus payments for 1998 to
certain executive officers, other than the President of TDS. The final amounts
or partial advances approved for the named executives are listed above in the
Summary Compensation Table.
 
    The annual compensation of the President (chief executive officer) of the
Company is proposed by the President to the Stock Option Compensation Committee
of the Board of Directors, and approved or adjusted by the Stock Option
Compensation Committee. In addition to the factors described above for all
executive officers in general, the Vice President-Human Resources prepares an
analysis of compensation paid to chief executive officers of other comparable
companies. These other companies include the companies included in the peer
group index described below under "Stock Performance Chart", as well as other
companies in the telecommunications industry and other industries with similar
characteristics, to the extent considered appropriate in the judgment of the
President, based on similar size, function, geography or otherwise. This
information is presented to the President who recommends a base salary and bonus
wlevel for himself. The Stock Option Compensation Committee approves the final
base salary and bonus of the President based on the recommendation of the
President. The Stock Option Compensation Committee approved a 1997 bonus of
$270,000 for the President, and increased his 1998 base salary to $570,000,
representing an increase of $55,000 or 10.7% over his base salary of $515,000 in
1997. The Stock Option Compensation Committee has not yet approved the
President's bonus for 1998, or the President's base salary for 1999.
 
    As with the other executive officers, the compensation of the President is
based on all facts and circumstances and the total mix of information rather
than related to any specific measures of performance. The Stock Option
Compensation Committee has access to numerous performance measures and financial
statistics prepared by the Company's financial personnel. This financial
information includes the audited financial statements of the Company, as well as
internal financial statements such as budgets and their results, operating
statistics and various analyses. The Stock Option Compensation Committee is not
limited in its analysis to the information presented to it by the President or
available from financial personnel, and may consider other factual or subjective
factors as the members of such committee deem appropriate in their compensation
decisions. No specific measures of performance are considered determinative in
the compensation of the President. Instead, all of the facts and circumstances
are taken into consideration by the Stock Option Compensation Committee in its
executive compensation decisions. Ultimately, it is the informed judgment of the
Stock Option Compensation Committee, based on the recommendation of the
President, that determines the salary and bonus for the President, this being
based on the total mix of information rather than on any specific measures of
performance.
 
    As discussed above for the other executive officers, the primary focus of
the Company is increasing long-term shareholder value through growth, measured
primarily in such terms as revenues, customer units in service, operating cash
flow (operating income plus depreciation and amortization) and operating income.
However, as discussed above, there is no quantifiable or direct relationship
between compensation and such or any other measures of performance. Instead,
such compensation decisions are made subjectively considering such performance
measurers, as well as all other facts and circumstances in general terms.
 
    The Stock Option Compensation Committee believes that the annual total base
salary and bonus compensation of the President has been set at a level less than
an average level for equally responsible executives at companies which it
considers comparable. The members of the Stock Option Compensation Committee
base this belief on their personal assessment and judgment of the President's
responsibilities in comparison to the chief executive officers and chief
operating officers of the companies included in the peer group index described
below under "Stock Performance Chart", as well as other companies in the
telecommunications industry and other industries with similar characteristics,
based on the information prepared by the Vice President of Human
 
                                      -19-
<PAGE>
Resources, as discussed above. The President has a substantial beneficial
interest in the Company, as described below under "Security Ownership of
Management", and will benefit together with other shareholders based on the
performance of the Company. The Stock Option Compensation Committee considers
this an important fact in connection with its review and approval or adjustment
of the salary and bonus recommended by the President for himself.
 
    At such time as the President approves the 1998 bonuses and 1999 salaries
for executive officers, and recommends the 1998 bonus and 1999 salary for
himself, he may also recommend to the Stock Option Compensation Committee
long-term compensation in the form of additional stock option grants, stock
appreciation rights or otherwise for executive officers and himself. The
long-term compensation decisions for executive officers will be made by the
Stock Option Compensation Committee in a manner similar to that described for
annual base salary and bonus decisions, except that the stock options will
generally vest over several years in a manner which will reflect the goal of
relating the long-term compensation of the executive officers, including the
President, to increases in shareholder value over the same period.
 
    The performance of the Company also bears upon the number of stock options
which will become awarded and exercisable with respect to the executive
officers. As indicated under the table "Individual Option/SAR Grants in 1998",
certain named executive officers received an award in 1998 of Performance
Options based on the achievement of certain levels of corporate and individual
performance in 1997.
 
    SECTION 162(M) OF THE CODE.  Section 162(m) of the Code generally limits to
$1 million the amount that a publicly held corporation is allowed each year to
deduct for the compensation paid to each of the corporation's chief executive
officer and the corporation's four most highly compensated officers other than
the chief executive officer, subject to certain exceptions. For various reasons,
the Company does not believe that the $1 million deduction limitation should
have a material effect on the Company in the immediate future. If the $1 million
deduction limitation is expected to have a material effect on the Company in the
future, the Company will consider ways to maximize the deductibility of
executive compensation, while retaining the discretion the Company deems
necessary to compensate executive officers in a manner commensurate with
performance and the competitive environment for executive talent.
 
    This Executive Officer Compensation Report is submitted by LeRoy T. Carlson,
Jr., sole member of the Compensation Committee; and by the Stock Option
Compensation Committee: George W. Off (Chairman) and Letitia G. C. Carlson.
 
STOCK PERFORMANCE CHART
 
    The following chart graphs the performance of the cumulative total return to
shareholders (stock price appreciation plus dividends) during the previous five
years in comparison to returns of the Standard & Poor's 500 Composite Stock
Price Index and a peer group index. The peer group index was constructed
specifically for the Company and includes the following companies: AllTel Corp.,
Centennial Cellular CP (Class A), Century Telephone Enterprise, Citizen
Utilities (Ser. B), Frontier Corp., Rural Cellular Corp (Class A), Western
Wireless Corp. (Class A) and TDS. In calculating the peer group index, the
returns of each company in the group have been weighted according to such
company's market capitalization at the beginning of the period.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    The sole member of the Compensation Committee is LeRoy T. Carlson, Jr.,
President of TDS. The primary function of the Compensation Committee is to
approve the annual salary, bonus and other cash compensation of officers and key
employees of TDS other than the President. LeRoy T. Carlson, Jr. is a member of
the Board of Directors of TDS, USM, AERL and TDS Telecom. LeRoy T. Carlson, Jr.
is also the Chairman of USM, AERL and TDS Telecom and, as such, approves the
executive officer annual compensation decisions for USM, AERL and TDS Telecom.
LeRoy T. Carlson, Jr. is compensated by TDS for his services to TDS and all of
its subsidiaries. However, USM and AERL reimburse TDS for a portion of such
compensation pursuant to intercompany agreements between TDS and such
subsidiaries. The Stock Option Compensation Committee of the Board of Directors
of TDS makes annual compensation decisions for the President of TDS and makes
long-term compensation decisions for all executive officers who are employees of
TDS. The members of the Stock Option Compensation Committee are George W. Off
(Chairman) and Letitia G. C. Carlson. The members of the Stock Option
Compensation Committee
 
                                      -21-
<PAGE>
are neither officers or employees of the Company or any of its subsidiaries nor
directors of any of the Company's subsidiaries. Long-term compensation for
executive officers who are employees of USM or AERL are approved by the stock
option compensation committees of USM and AERL respectively. The stock option
compensation committees of USM and AERL are composed of directors of such
subsidiaries who are neither officers or employees of TDS or any of its
subsidiaries nor directors of TDS.
 
    In addition to such compensation committee interlocks and insider
participation in compensation decisions, the Company and certain related parties
are involved in the following relationships and transactions.
 
    ISSUANCE OF TDS SHARES IN CONNECTION WITH CERTAIN ACQUISITIONS.  The Company
may issue TDS securities in connection with the acquisition of cellular
interests on behalf of USM. At the time such acquisitions are closed, the
acquired cellular interests are generally transferred to USM, which has
reimbursed TDS by issuing USM securities to TDS or by increasing the balance due
to TDS under a revolving credit agreement between TDS and USM. The fair market
value of the USM securities issued to TDS in connection with these transactions
is calculated in the same manner and over the same time period as the fair
market value of the TDS securities issued to the sellers in such acquisitions.
During 1998, USM issued 45,988 USM Common Shares to TDS to reimburse TDS for
29,999 TDS Common Shares issued for such cellular interests.
 
    OTHER RELATIONSHIPS AND RELATED TRANSACTIONS.  Walter C. D. Carlson, a
director of TDS, USM and AERL, Michael G. Hron, Secretary of TDS and certain TDS
subsidiaries, William S. DeCarlo, the Assistant Secretary of TDS and certain TDS
subsidiaries, Stephen P. Fitzell, the Secretary of certain TDS subsidiaries, and
Sherry S. Treston, the Assistant Secretary of certain TDS subsidiaries, are
partners of Sidley & Austin, the principal law firm of TDS and its subsidiaries.
Walter C. D. Carlson is a trustee and beneficiary of a voting trust which
controls TDS.
 
         SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT
 
    On February 28, 1999, the Company had outstanding and entitled to vote
54,391,873 Common Shares, par value $.01 per share (excluding 643,952 Common
Shares held by the Company and 484,012 Common Shares held by a subsidiary of the
Company); 6,949,904 Series A Common Shares, par value $.01 per share; and
241,772 Preferred Shares, par value $.01 per share. Each of the outstanding
Common Shares and Preferred Shares is entitled to one vote and each of the
outstanding Series A Common Shares is entitled to ten votes. Accordingly, the
voting power of all outstanding Series A Common Shares was 69,499,040 votes, and
the total voting power of all outstanding shares of all classes of capital stock
was 124,132,685 votes at February 28, 1999, with respect to matters other than
the election of directors.
 
SECURITY OWNERSHIP OF MANAGEMENT
 
    The following table sets forth at February 28, 1999, or the latest
practicable date, the number of Common Shares and Series A Common Shares
beneficially owned, and the percentage of the outstanding shares of each such
class so owned by each director and nominee for director of the Company, by each
of the executive officers named in the Summary Compensation Table and by all
directors and executive officers as a group.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
 
    Section 16 of the Securities Exchange Act of 1934, as amended, and the rules
and regulations thereunder require the Company's directors and officers, and
persons who are deemed to own more than ten percent of the Common Shares
(collectively, the "Reporting Persons"), to file certain reports ("Section 16
Reports") with the SEC with respect to their beneficial ownership of Common
Shares. The Reporting Persons are also required to furnish the Company with
copies of all Section 16 Reports they file.
 
    Based on a review of copies of Section 16 Reports furnished to the Company
by the Reporting Persons and written representations by directors and officers
of the Company, the Company believes that all Section 16 filing requirements
applicable to the Reporting Persons during and with respect to 1998 were
complied with on a timely basis.

                                      A-2
<PAGE>
SECTION 5. ELIGIBILITY AND PARTICIPATION.
 
    (a) Any Eligible Employee of an Employer shall be eligible to participate in
the Plan as of the first Entry Date following such Eligible Employee's
satisfaction of the eligibility service requirement, or, if later, the first
Entry Date following the date on which the Eligible Employee's Employer adopts
the Plan. For purposes of this subsection, an Eligible Employee shall have
satisfied the eligibility service requirement if he or she has completed at
least three months of continuous service with an Employer. For the sole purpose
of calculating length of service under the Plan, Employees shall be credited
with service for an Employer, an Affiliate and any other member of the
Controlled Group (even though such service may have been performed prior to the
Company's acquisition of such member or prior to the time such Affiliate became
an Affiliate). No eligibility provision hereof shall permit or deny
participation in the Plan in a manner contrary to the applicable requirements of
the Code and the regulations promulgated thereunder.
 
    (b) As of the first Entry Date as of which an Eligible Employee is eligible
to participate in the Plan as described in subsection (a) of this Section, or as
of any date thereafter, an Eligible Employee may elect to become a Participant
in the Plan by making an election to enroll herein, in the time and manner
prescribed by the Committee. Such Eligible Employee's election shall specify his
or her chosen rate of payroll deduction contributions described in Section 6,
and shall authorize the Eligible Employee's Employer to withhold a portion of
his or her Compensation in the amount of any such payroll deduction
contributions. The Eligible Employee's election shall become effective as soon
as administratively practicable after such election is received by the Benefits
Representative or its designee.
 
    (c) If a Participant is transferred from one Employer to another Employer,
such transfer shall not terminate the Participant's participation in the Plan.
Such transferred Participant may continue to make payroll deduction
contributions under the Plan provided such Participant takes such action as the
Committee may require, if any, in the time and manner prescribed by the
Committee. If a Participant is transferred from an Employer to an Affiliate that
is not a participating Employer, such transfer shall not terminate the
Participant's participation in the Plan. However, such Participant's payroll
deduction contributions shall be suspended during such period of employment with
the Affiliate. If such Participant subsequently is transferred from such
Affiliate to a participating Employer, such Participant can resume making
payroll deduction contributions under the Plan provided such Participant takes
such action as the Committee may require, if any, in the time and manner
prescribed by the Committee.
 
    (d) If an individual terminates employment with all Employers and Affiliates
so as to discontinue participation in the Plan, and such individual is
subsequently reemployed by an Employer, such individual shall not be required
again to satisfy the eligibility service requirement described in subsection (a)
of this Section, but rather shall be eligible to recommence participation as of
the first Entry Date after his or her date of reemployment (or as soon as
administratively practicable thereafter).
 
    (e) Notwithstanding anything herein to the contrary, no member of the
Committee shall be eligible to participate in the Plan.
 
SECTION 6. PARTICIPANT CONTRIBUTIONS.
 
    (a) Upon enrollment in the Plan a Participant shall elect, in the manner
described in Section 5(b), a rate of payroll deduction contributions in an
amount equal to a whole percentage not less than 1% and not more than 15% of
such Participant's Compensation for each payroll period, beginning as soon as
administratively practicable after the Entry Date as of which such Participant
commences participation in the Plan.
 
    (b) A Participant shall have the right from time to time to increase or
decrease his or her designated rate of payroll deductions under the Plan by
making an election authorizing such increase or decrease, in the time and manner
prescribed by the Committee. Such election shall specify a percentage rate of
payroll deduction contributions not less than 0% and not more than 15%. A
Participant also may elect to withdraw from the Plan for an Offering Period, as
described in Section 8. A decrease of a payroll deduction election hereunder to
0% shall not be treated as a withdrawal from the Plan for this purpose. A
Participant's election to change his or her rate of payroll deductions hereunder
shall become effective as soon as administratively practicable after such
election is received by the Benefits Representative or its designee.
 
    (c) A Participant's designated rate of payroll deductions as in effect on
the last day of an Offering Period shall continue in effect during the
subsequent Offering Period unless and until the Participant files a change in
the rate of payroll deductions as described in subsection (b) of this Section,
or elects to withdraw from participation for the Offering Period as described in
Section 8.
 
                                      A-3
<PAGE>
    (d) All payroll deductions in the possession of the Company shall be
segregated from the general funds of the Company. The Committee shall cause to
be established a separate Employee Stock Purchase Account on behalf of each
Participant to which shall be credited his or her payroll deduction
contributions made under the Plan. Such accounts shall be solely for accounting
purposes, and there shall be no segregation of assets among the separate
accounts. Such accounts shall not be credited with interest or other investment
earnings. Each Employee Stock Purchase Account shall be restricted to the uses
provided herein until such time as the Company applies the amounts credited
thereto to purchase Common Shares under the Plan on behalf of Participants.
 
SECTION 7. PURCHASE OF COMMON SHARES.
 
    (a) Subject to a Participant's right of withdrawal from the Plan for an
Offering Period as described in Section 8 hereof, the balance of each
Participant's Employee Stock Purchase Account shall be applied on each Purchase
Date to purchase Common Shares by dividing the balance of such account as of
such date by the Purchase Price of a Common Share as of such date. A
Participant's purchase of Common Shares shall be rounded to the nearest one-ten
thousandth of a share (or such other fractional interest prescribed by the
Committee). The Participant's Employee Stock Purchase Account shall be debited
by the amounts applied to purchase such Common Shares, and the Participant's
Stock Account shall be credited with such Common Shares.
 
    (b) If the employment of an individual who is a Participant in the Plan is
transferred to an Affiliate that is not an Employer, then the Participant's
payroll deductions shall be suspended and the balance of the Participant's
Employee Stock Purchase Account shall be applied to purchase Common Shares on
the Purchase Date next occurring after the effective date of such transfer,
except to the extent the individual withdraws from the Plan for the remainder of
the Offering Period as described in Section 8. Upon the Participant's transfer
from such Affiliate back to an Employer, the Participant may resume active
participation in the Plan in the time and manner described in Section 5(c).
 
    (c) Upon termination of employment because of the Participant's retirement,
the balance of the Participant's Employee Stock Purchase Account shall be
applied to purchase Common Shares for the Participant as of the Purchase Date
next occurring after the date of the Participant's termination of employment,
unless the Participant elects, in the manner prescribed by the Committee, to
withdraw from the Plan as described in Section 8 on or before the earlier of the
15th day (or such shorter period prescribed by the Committee) prior to the
Purchase Date next occurring after the date of the Participant's termination of
employment.
 
    (d) Upon termination of employment because of the Participant's death, the
balance of the Participant's Employee Stock Purchase Account, after crediting
such account with payroll deductions for any Compensation due and owing, shall
be applied to purchase Common Shares for the Participant's estate as of the
Purchase Date next occurring after the Participant's death, unless the executor
or administrator of the Participant's estate elects, in the manner prescribed by
the Committee, to withdraw from the Plan as described in Section 8 on or before
the 15th day (or such shorter period prescribed by the Committee) prior to the
Purchase Date next occurring after the Participant's death.
 
    (e) Upon termination of employment for any reason other than transfer to an
Affiliate as described in subsection (b) of this Section, retirement as
described in subsection (c) of this Section, or death as described in subsection
(d) of this Section, the Participant's participation in the Plan shall cease and
the entire balance of the Participant's Employee Stock Purchase Account shall be
refunded to the Participant as soon as administratively practicable thereafter.
 
    (f) Notwithstanding any provision of this Plan to the contrary, a
Participant's right to purchase Common Shares during any calendar year shall be
limited to the extent necessary so that the Participant's right to purchase
Common Shares under this Plan and under all other employee stock purchase plans
maintained by members of the Controlled Group shall not accrue at a rate in
excess of $25,000 of the Fair Market Value of Common Shares (determined on the
grant date) for any calendar year determined in accordance with section
423(b)(8) of the Code and regulations promulgated thereunder. Any portion of the
balance of a Participant's Employee Stock Purchase Account in excess of the
amount necessary to purchase shares on a Purchase Date in accordance with the
foregoing limitation shall remain credited to such account and shall be
available for purchase of Common Shares as of the next Purchase Date; PROVIDED,
HOWEVER, that if a balance remains in a Participant's Employee Stock Purchase
Account as of the last Purchase Date in an Offering Period as a result of the
application of the foregoing limitation, such balance shall be refunded to the
Participant as soon as administratively practicable thereafter.
 
    (g) Notwithstanding any provision of the Plan to the contrary, the maximum
number of shares which shall be available for purchase under the Plan shall be
210,000 Common Shares, subject to adjustment as provided in
 
                                      A-4
<PAGE>
Section 11. The Common Shares to be sold under this Plan may, at the election of
the Company, be treasury shares, shares originally issued for such purpose or
shares purchased by the Company. In the event the amount of shares to be
purchased on behalf of all Participants collectively exceeds the shares
available for purchase under the Plan, the number of Common Shares to be
purchased by each Participant under this Section shall be determined by
multiplying the number of shares which the Participant elected to purchase on
such Purchase Date by the following fraction (or by applying such other
equitable adjustment on a uniform basis as may be determined by the Committee):
 
         Total number of shares available for purchase on Purchase Date
  ----------------------------------------------------------------------------
 Total number of shares elected to be purchased by all Participants on Purchase
                                      Date
 
Any portion of the balance of a Participant's Employee Stock Purchase Account
that is not applied to purchase Common Shares on a Purchase Date as a result of
the foregoing adjustment shall be refunded to the Participant as soon as
administratively practicable thereafter.
 
SECTION 8. PARTICIPANT'S RIGHT TO WITHDRAW FOR AN OFFERING PERIOD.
 
    At any time during an Offering Period, but in no event later than 15 days
(or such shorter period prescribed by the Committee) prior to the last Purchase
Date in the Offering Period, a Participant may elect to withdraw from
participation in the Plan for such Offering Period. A withdrawal election shall
be made in the time and manner prescribed by the Committee. Upon a Participant's
election to withdraw from the Plan for an Offering Period pursuant to this
Section, the amount credited to the Participant's Employee Stock Purchase
Account shall be refunded to the Participant as soon as is administratively
practicable, and such Participant's participation in the Plan for the remainder
of such Offering Period shall be terminated. The Participant shall be eligible
to recommence participation in the Plan as of the next Offering Period.
 
SECTION 9. SUSPENSION ON ACCOUNT OF EMPLOYEE'S HARDSHIP WITHDRAWAL.
 
    If a Participant makes a hardship withdrawal from the Telephone and Data
Systems, Inc. Tax-Deferred Savings Plan or any other plan with a cash or
deferred arrangement qualified under section 401(k) of the Code which plan is
sponsored, or participated in, by any Employer, such Participant shall be
suspended from making payroll deductions under this Plan for a period of twelve
months from the date of such hardship withdrawal. The balance of such
Participant's Employee Stock Purchase Account shall be applied to purchase
Common Shares on the Purchase Date next occurring after the effective date of
such hardship withdrawal, except to the extent the Participant withdraws from
the Plan for the remainder of the Offering Period as described in Section 8, or
discontinues participation in this Plan on account of the Participant's
termination of employment. After the expiration of such twelve-month period, the
Participant may resume active participation in the Plan by electing to resume
making payroll deductions hereunder, in the time and manner prescribed by the
Committee, unless the Participant has withdrawn from participation in the Plan
as described in Section 8 for the Offering Period which contains the date of
expiration of such twelve-month period.
 
SECTION 10. STOCK ACCOUNT; ISSUANCE OF CERTIFICATES.
 
    (a) A Stock Account shall be established on behalf of each Participant for
whom shares are purchased under this Plan (or, if so designated by the
Participant, on behalf of such Participant and one other person as such
Participant may designate as joint tenants with right of survivorship).
 
    (b) As of each Purchase Date, the Common Shares purchased on a Participant's
behalf (including the right to fractional shares) shall be credited to the
Participant's Stock Account and shall be registered in the name of the Nominee.
All rights accruing to an owner of record of such Common Shares, including
dividend, voting and tendering rights, shall belong to the Participant for whom
such Stock Account is established (including any joint tenant or, in the case of
a deceased Participant, the Participant's estate).
 
    (c) The Nominee shall establish procedures pursuant to which a Participant
(including any joint tenant or, in the case of a deceased Participant, the
executor or administrator of the Participant's estate) can elect that the shares
credited to the Participant's Stock Account shall be registered in the name of
such Participant, or in the names of such Participant and one other person as
the Participant may designate as joint tenants with right of survivorship, as
the case may be. Such a joint tenancy designation shall not apply to shares
registered by the Participant's estate after the Participant's death. As soon as
practicable after such election, certificates representing such shares shall be
issued to the Participant (including any joint tenant or, in the case of a
deceased Participant, to
 
                                      A-5
<PAGE>
the Participant's estate). The Nominee shall also establish procedures pursuant
to which a Participant (or the executor or administrator of the Participant's
estate) can receive a cash payment in lieu of any fractional shares credited to
his or her Stock Account.
 
SECTION 11. CHANGES IN THE COMPANY'S CAPITAL STRUCTURE.
 
    (a) The existence of the Plan shall not affect in any way the right or power
of the Company or its shareholders to make or authorize any adjustment,
recapitalization, reorganization or other change in the Company's capital
structure or its business, or any merger or consolidation of the Company, or any
issue of bonds, debentures, preferred or prior preference stock that affects any
class of Common Shares or the rights thereof, or the dissolution or liquidation
of the Company, or any sale or transfer of all or any part of its assets or
business, or any other corporate act or proceeding, whether of a similar
character or otherwise.
 
    (b) If, during the term of the Plan, the Company shall effect (i) a
distribution or payment of a dividend on Common Shares in shares of the Company,
(ii) a subdivision of outstanding Common Shares by a stock split or otherwise,
(iii) a combination of the outstanding Common Shares into a smaller number of
shares by a reverse stock split or otherwise, or (iv) an issuance by
reclassification or other reorganization of Common Shares (other than by merger
or consolidation), then each Participant shall be entitled to receive upon the
purchase of shares pursuant to this Plan such shares of the Company which the
Participant would have owned or would have been entitled to receive after the
happening of such event had the Participant purchased Common Shares pursuant to
the Plan immediately prior to the happening of such event. If any other event
shall occur that, in the judgment of the Board, necessitates adjusting the
Purchase Price of Common Shares, the number of Common Shares offered for
purchase hereunder, or other terms of the Plan, the Board shall take any action
that in its judgment shall be necessary to preserve each Participant's rights
substantially proportionate to the rights existing prior to such event. To the
extent that any event or action pursuant to this paragraph shall entitle
Participants to purchase additional Common Shares or other shares of the
Company, the shares available under this Plan shall be deemed to include such
additional Common Shares or such other shares of the Company.
 
    (c) In the event of a merger of one or more corporations into the Company,
or a consolidation of the Company and one or more corporations in which the
Company shall be the surviving corporation, each Participant in the Plan shall,
at no additional cost, be entitled, upon his or her payment for all or part of
the Common Shares purchasable by the Participant under the Plan, to receive
(subject to any required action by shareholders) in lieu of the number of Common
Shares which he or she was entitled to purchase, the number and class of shares
of stock or other securities to which such holder would have been entitled
pursuant to the terms of the agreement of merger or consolidation if,
immediately prior to such merger or consolidation, such holder had been the
holder of record of the number of Common Shares equal to the number of shares
paid for by the Participant.
 
    (d) If the Company is merged into or consolidated with another corporation
under circumstances in which the Company is not the surviving corporation, or if
the Company sells or otherwise disposes of substantially all of its assets to
another corporation during the term of the Plan: (i) subject to the provisions
of clause (ii) below, after the effective date of such merger, consolidation or
sale, as the case may be, each holder of a right to purchase shall be entitled
to receive, upon his or her payment for all or part of the Common Shares
purchasable by the Participant under the Plan and receive in lieu of such
shares, shares of such stock or other securities as the holders of Common Shares
received pursuant to the terms of the merger, consolidation or sale; and (ii)
all outstanding rights to purchase may be canceled by the Board as of the
effective date of any such merger, consolidation or sale, provided that (A)
notice of such cancellation shall be given to each Participant and (B) each such
Participant shall have the right to purchase, during a 30-day period preceding
the effective date of such merger, consolidation or sale, all or any part of the
shares allocated to the Participant under the terms of the Plan.
 
    (e) Except as hereinbefore expressly provided, the issue by the Company of
shares of stock of any class, or securities convertible into shares of stock of
any class, for cash or property, or for labor or services either upon direct
sale or upon the exercise of rights or warrants to subscribe therefor, or upon
conversion of shares or obligations of the Company convertible into such shares
or other securities, shall not affect, and no adjustment by reason thereof shall
be made with respect to, the number or price of Common Shares then available for
purchase under the Plan.
 
                                      A-6
<PAGE>
SECTION 12. AMENDMENT OF THE PLAN.
 
    The Board may at any time, and from time to time, amend the Plan in any
respect; PROVIDED, HOWEVER, that any amendment that changes the number of shares
to be reserved under the Plan (other than as provided in Section 11), or that
otherwise requires stockholder approval under applicable law, shall not be
effective unless stockholder approval is obtained in the time and manner
prescribed by law.
 
SECTION 13. TERMINATION OF THE PLAN.
 
    While it is intended that the Plan remain in effect until the Termination
Date, the Board may terminate the Plan at any time in its discretion. Upon
termination of the Plan, the Committee shall terminate payroll deductions and
shall apply the balance of each Participant's Employee Stock Purchase Account to
purchase Common Shares as described in Section 7 as if such termination date
were a Purchase Date under the Plan and were the last day of an Offering Period.
Notwithstanding the foregoing, upon termination of the Plan, a Participant may
elect, in the time and manner prescribed by the Committee, to withdraw from
participation in the Plan. As soon as administratively practicable after the
termination of the Plan, the Committee shall refund to the Participant any
amount in his or her Employee Stock Purchase Account, if any, that has not been
applied to purchase Common Shares as a result of the Participant's election to
withdraw from the Plan or as a result of the application of any limitation
hereunder.
 
    Notwithstanding any provision in the Plan to the contrary, the Plan shall
automatically terminate as of the Purchase Date on which all Common Shares
available for purchase under the Plan shall have been purchased by Participants
under the Plan.
 
SECTION 14. MISCELLANEOUS.
 
    (a) The Plan is subject to the approval of a majority of the votes cast on
the matter by the stockholders of the Company within twelve months before or
after its adoption by the Board.
 
    (b) The right to purchase Common Shares under this Plan shall not be
transferable by any Participant other than by will or the laws of descent and
distribution, and must be exercisable, during his or her lifetime, only by the
Participant.
 
    (c) No Participant shall have rights or privileges of a stockholder of the
Company with respect to shares purchasable under this Plan unless and until the
Participant shall become the holder of record of one or more Common Shares.
 
    (d) The Company is not obligated to repurchase any Common Shares acquired
under the Plan.
 
    (e) The sale and delivery of Common Shares under the Plan shall be in
compliance with relevant statutes and regulations of governmental authorities,
including state securities laws and regulations, and with the regulations of
applicable stock exchanges.
 
    (f) This Plan and all determinations made hereunder and action taken
pursuant hereto shall be governed by the laws of the State of Illinois and
construed in accordance therewith.
 
    (g) Each Employer, by adopting the Plan, appoints the Company and the Board
as its agents to exercise on its behalf all of the powers and authorities hereby
conferred upon the Company and the Board by the terms of the Plan, including,
but not by way of limitation, the power to amend and terminate the Plan. The
authority of the Company and the Board to act as such agents shall continue for
as long as necessary to carry out the purposes of the Plan.
