                                VOTING TRUST AGREEMENT

                              DATED AS OF JUNE 30, 1989


     THIS VOTING TRUST AGREEMENT is made as of the thirtieth day of June, 
1989, between such holders of the Series A Common Shares, par value $1.00 per 
share ("Series A Common"), of TELEPHONE AND DATA SYSTEMS, INC., an Iowa 
corporation (the "Company"), as may become parties to this Agreement (the 
"Depositing "Certificate Holders" or the "Certificate Holders"), and WALTER 
C.D. CARLSON, LETITIA G.C. CARLSON, LEROY T. CARLSON, JR., MELANIE J. HEALD 
and DONALD C. NEBERGALL, or their successors (the "Trustees").

     The Depositing Shareholders are owners of Series A Common and deem it to 
be in their mutual best interests to confer upon the Trustees the right to 
vote and to act with respect to such shares, subject to the terms and 
conditions of this Agreement.

     In consideration of the mutual promises and covenants herein contained 
and other good and valuable consideration, receipt of which is hereby 
acknowledged, it is agreed between the parties as follows:



                                  ARTICLE I

                              DEPOSIT OF SHARES

     1.1  DEPOSIT TO TRUSTEES.  Each shareholder of the Company who becomes a 
party hereto by signing this Agreement agrees to deposit or cause to be 
deposited with the Trustees, to be held by them pursuant to the provisions of 
this Agreement, one or more stock certificates representing shares of Series 
A Common now owned by him or her, duly endorsed in blank or to the Trustees, 
or accompanied by proper instruments of assignment and transfer duly executed 
in blank or to the Trustees, and accompanied by any revenue stamps required 
for the transfer, or shares of Series A Common held in non-certificated form 
pursuant to the Company's dividend reinvestment plan, represented by 
appropriate transfer documents, and to accept in lieu thereof a Voting Trust 
Certificate or Certificates issued hereunder in the form herein provided.

     1.2  TERM.  Each deposit made pursuant to Section 1.1 shall continue 
from  the date this Agreement becomes effective until June 30, 2009, unless 
sooner terminated as herein provided.  This Agreement shall be effective at 
12:01 a.m. on the day following the day on which the last of the following 
events occurs:

                                       2


          (a)  the Federal Communications Commission order giving consent to 
the implementation of this Agreement becomes effective or the Trustees 
determine no such order is required; or

          (b)  the signing of this Agreement by those Certificate Holders who 
deposit or agree to deposit, in the aggregate, a majority of the Company's 
then issued and outstanding Series A Common Shares, par value $1.00 per share;

provided, however, that the Trustees appointed hereunder may delay the 
effective date as required to prevent the implementation of the Agreement 
from interfering with any RSA or MSA applications pending before the Federal 
Communications Commission.

     1.3  ADDITIONAL DEPOSITS.  Any owner of shares of Series A Common may at 
any time apply to the Trustees for permission to deposit stock certificates 
representing shares of Series A Common, accepting in lieu thereof Voting 
Trust Certificates issued hereunder in the form hereinafter provided.  In 
consideration of the original deposit of Series A Common by the Depositing 
Shareholders, the Trustees, by an "eight-vote majority" (as defined in 
Subsection 7.2(b)), may accept for deposit and receive in trust hereunder any 
additional stock certificates representing shares of Series A Common owned by 
any shareholder whomsoever and hold any certificates so deposited in trust 
under the terms and 

                                       3


conditions of this Agreement.  Such deposit of additional stock certificates 
representing shares of Series A Common and the acceptance of Voting Trust 
Certificates by the depositor thereof shall have the same force and effect as 
though such depositor had in fact subscribed his or her name to this 
Agreement.  The Trustees, by an eight-vote majority, may also accept for 
deposit any Common Shares of the Company ("Common Shares").

     1.4  SERIES A COMMON.

          (a) The term "Series A Common" as hereafter used in this Agreement 
shall also be deemed to include:

               (i)  any shares of a class other than the Company's existing 
class of Series A Common Shares, par value $1.00 per share, held or to be 
held by the Trustees pursuant to this Agreement;

               (ii)  any securities convertible into shares of Series A 
Common, including any shares or securities deemed to be Series A Common 
pursuant to this Section 1.4;

               (iii)  any rights to subscribe to Series A Common, including 
any shares or securities deemed to be Series A Common pursuant to this 
Section 1.4;
                                       4



          (b)  Wherever reference is made in this Agreement to shares 
of Series A Common "beneficially owned," such reference shall be to those 
shares of Series A Common represented by the Voting Trust Certificates and to 
those shares of Series A Common acquired in respect of an existing Voting 
Trust Certificate by reason of participation in the Company's dividend 
reinvestment plan.

          (c)  Wherever reference is made in this Agreement to votes 
"beneficially held" by a Certificate Holder, such reference shall be to votes 
described in Subsection 6.5(c).

                                           
                                   ARTICLE II

                           VOTING TRUST CERTIFICATES


     2.1  ISSUANCE OF VOTING TRUST CERTIFICATES.  All stock certificates for 
shares of Series A Common at any time delivered to the Trustees hereunder or 
thereafter acquired by the Trustees as provided in this Agreement shall be 
held and disposed of by the Trustees under and pursuant to the terms and 
conditions of this Agreement.  The Trustees, in exchange for the stock 
certificates so deposited hereunder, shall cause to be issued and delivered 
to the Certificate Holders Voting Trust Certificates 

                                       5


for the appropriate number of shares of Series A Common in substantially the 
form set forth in Exhibit A attached hereto or as revised to reflect the 
deposit of any shares other than the Company's existing issue of Series A 
Common Shares, par value $1.00 per share.  The Trustees shall not issue 
Voting Trust Certificates with respect to shares purchased through the 
Company's dividend reinvestment plan until such shares are reduced to stock 
certificate form, but such shares shall nevertheless be subject to this 
Agreement if purchased with dividends earned with respect to shares which are 
subject to this Agreement.

     2.2  FORM OF CERTIFICATES.  The Trustees may issue temporary typewritten 
or printed Voting Trust Certificates conforming generally to the form set 
forth on Exhibit A and may cause the same to be exchanged for definitive 
Voting Trust Certificates in substantially such form when the same are 
prepared.  The Voting Trust Certificates shall be executed by no fewer than 
three Trustees, with copies of such Certificates sent to all nonexecuting 
Trustees.  The Trustees, under such rules as they in their discretion may 
prescribe with respect to indemnity or otherwise, shall provide for the 
issuance and delivery of new Voting Trust Certificates in lieu of lost, 
stolen or destroyed Certificates or in exchange for mutilated Certificates.

                                       6


                                  ARTICLE III

                              WITHDRAWAL OF SHARES

     3.1  WITHDRAWAL.  Any Certificate Holder shall be permitted to withdraw 
Common Shares, from time to time, upon the surrender Certificates, of the 
corresponding Voting Trust Certificate or Certificates, subject to the 
provisions of this Article.  The following conditions, limitations and 
procedures shall apply to any such withdrawal:

     (a)  AUTHORITY TO CONVERT.  Any Certificate Holder electing to withdraw 
Common Shares shall be deemed to have instructed, directed and authorized the 
Trustees to convert a sufficient number of shares of his or her beneficially 
owned Series A Common into Common Shares to the extent necessary to effect 
such withdrawal.

     (b)  WITHDRAWALS UPON TWENTY DAYS' NOTICE.  Any Certificate Holder may 
make aggregate withdrawals during any calendar year of not more than 7,500 
Common Shares (as adjusted by Section 8.1), provided written notice of such 
intended withdrawal is given to the Trustees no less than twenty days prior 
to the date of withdrawal specified in such written notice.  No such 
withdrawal notice shall be revoked except as provided in Subsection 3.1(i).

                                       7


     (c)  WITHDRAWALS UPON SIXTY DAYS' NOTICE.  Any Certificate Holder may 
make aggregate withdrawals during any calendar year of more than 7,500 Common 
Shares (as adjusted by Section 8.1), but not more than five percent (5%) of 
the number of shares of his or her beneficially owned Series A Common as of 
the beginning of the calendar year in which such withdrawal occurs (as 
adjusted by Section 8.1 for capital changes occurring during such calendar 
year), provided written notice of such intended withdrawal is given to the 
Trustees no less than sixty days prior to the date of withdrawal specified in 
such written notice.  No such withdrawal notice shall be revoked except as 
provided in Subsection 3.1(i).

     (d) WITHDRAWALS UPON NINE MONTHS' NOTICE.  In addition to any 
withdrawals permitted pursuant to Subsections 3.1(b) and 3.1(c), any 
Certificate Holder may make additional withdrawals  during any calendar year 
which cause his or her aggregate withdrawals for such year to be not more 
than 300,000 Common Shares (as adjusted by Section 8.1), provided written 
notice of such intended withdrawal is given to the Trustees no less than nine 
months prior to the date of withdrawal specified in such written notice.  No 
such withdrawal notice shall be revoked unless cancelled by written notice 
received at least 105 or more 

                                       8


days prior to the specified date of withdrawal or except as provided in 
Subsection 3.1(i).

     (e)  WITHDRAWALS SUBSEQUENT TO TRANSFER.  During any calendar year in 
which a Certificate Holder makes a gratuitous intervivos transfer of a Voting 
Trust Certificate, neither such transferor nor any transferee of such 
Certificate may make a withdrawal to the extent that the number of Common 
Shares withdrawn by such transferor during such year, when added to the 
number of Common Shares represented by Voting Trust Certificates transferred 
by such transferor during such year and deemed to be withdrawn by a 
transferee during such year, would exceed the limitation set forth in 
Subsection 3.1(d) For purposes of this Subsection 3.1(e), any such transferee 
shall be deemed to withdraw Common Shares represented by Voting Trust 
Certificates transferred by a transferor only after such transferee has 
withdrawn shares equal in number to (i) the number of shares of Series A 
Common beneficially-owned by and withdrawable by such transferee as of the 
beginning of such year plus (ii) the number of shares of Series A Common 
represented by Voting Trust Certificates acquired for value by such 
transferee during such year prior to the date of withdrawal.  If the 
transferee receives a gratuitous intervivos transfer of Voting Trust 
Certificates from more than one transferor during such year, he or she shall 
be deemed to have withdrawn Common Shares represented by Voting 

                                       9


Trust Certificates transferred by each such transferor, if at all (after 
application of the preceding sentence), on the following basis:

               (i)  to the extent withdrawals are permitted with respect to 
each such transferor, in proportion to the number of shares of Series A 
Common represented by Voting Trust Certificates received during such year by 
such transferee from each such transferor, and

              (ii)  to the extent withdrawals would not be permitted with 
respect to any transferor because of the limitations imposed by this 
Subsection 3.1(e), in proportion to the number of shares of Series A Common 
represented by the Voting Trust Certificates received during such year by 
such transferee from each transferor with respect to whom withdrawals would 
be permitted.

The ability to make a withdrawal shall be determined as of the date such
withdrawal is requested, taking into account all prior withdrawal requests
whether or not such withdrawal has been completed.  A transferee of a Voting
Trust Certificate from a deceased Certificate Holder may not make a withdrawal
of any Common Shares represented by such Certificate during the year in which
such decedent dies, except for that number of shares which 

                                       -10-



bears the same proportion to the number of shares which such decedent was 
eligible to withdraw immediately prior to his or her death as the number of 
shares represented by such Certificate bears to the total number of shares 
beneficially-owned by such decedent immediately prior to his or her death.  
No such withdrawals shall cause such transferee's withdrawals for the year to 
exceed the limitation imposed by Subsection 3.1(d).

          (f)  PERMITTED WITHDRAWALS IN RESPECT OF A DECEDENT.  Notwithstanding
the limitations on withdrawals set forth in the preceding subsections of this
Article III, upon the death of a Certificate Holder, each transferee of such
decedent's Voting Trust Certificates may withdraw additional Common Shares so
long as the aggregate value of all withdrawals made pursuant to this Subsection
3.1(f) does not exceed the total amount of transfer and succession taxes payable
by reason of decedent's death plus the amount of administration expenses
deductible (whether or not actually deducted) pursuant to Sections 2053 and 2054
of the Internal Revenue Code of 1986, as amended, or any amended or successor
provisions, which such transferee is legally obligated to pay.  Any such
withdrawals with respect to transfer and succession taxes must be made prior to
the due date or dates of such taxes, and any such withdrawals with respect to
administration expenses must be made within nine-months of the decedent's death,
provided written notice of such intended withdrawal is given to 

                                   -11-



the Trustees no less than sixty days prior to the date of withdrawal as 
specified in such written notice.  For purposes of this Subsection 3.1(f), 
the value of any withdrawn shares shall be deemed to be the value determined 
with respect to such shares pursuant to Subsection 3.2(g). No such withdrawal 
notice shall be revoked except as provided in Subsection 3.1(i).

     (g) NOTICE OF WITHDRAWAL. The written notice of withdrawal required 
pursuant to Subsections 3.1(b), (c), (d) or (f) shall be substantially in the 
form prescribed in Exhibit B attached hereto.

     (h)  WAIVER OF NOTICE.  Any notice required pursuant to Section 3.1
may be reduced to sixty days by the "six-vote majority" (as defined in
Subsection 7.2(b)) of the Trustees; provided, however, that the required six
votes shall be reduced by the number of votes held by any Trustee who is the
Certificate Holder requesting such waiver, such Trustee being excluded from
voting with respect to such matter.

     (i) CANCELLATION OF OTHERWISE IRREVOCABLE NOTICE OF WITHDRAWAL. 
Notwithstanding that any notice of withdrawal may be irrevocable pursuant to 
the preceding provisions of this Section 3.1, the Trustees may, without 
liability to any person, permit the cancellation of such withdrawal notice up 
to fifteen 

                                       -12-



days prior to the specified date of withdrawal, provided that the cancelling 
Certificate Holder reimburses the Trustees for all expenses incurred by the 
Trustees with respect to such withdrawal. Such cancellation shall be approved 
by a six vote majority of the Trustees; provided, however, that the required 
six votes shall be reduced by the number of votes held by the Trustee who is 
the Certificate Holder wishing to cancel such withdrawal notice, such Trustee 
being excluded from voting with respect to such matter.  In the event any 
such cancellation is permitted by the Trustees, neither the Certificate 
Holder requesting such withdrawal nor the Trustees shall be liable to any 
other Certificate Holder for any expenses or damages, consequential or 
otherwise, that such other party or other Certificate Holder may allege to 
have been incurred in reliance on or otherwise as a result of such notice of 
withdrawal or cancellation.  The Trustees shall not be required to permit or 
deny cancellation except in their sole and uncontrolled discretion.  The 
Trustees shall, within five business days, provide written notice of any 
cancellation to all Optionees (as defined in Subsection 3.2(a)).

     3.2 OPTION TO ACQUIRE.

          (a)  NOTICE OF INTENT TO WITHDRAW TO OPTIONEES.  Upon the Trustees' 
receipt of notice from a Certificate Holder of such person's intention to 
make a withdrawal pursuant to Section 3.1 

                                       -13-



which would cause such person's aggregate withdrawals for the calendar year 
to equal or exceed 150 (as adjusted by Section 8.1) Common Shares the 
Trustees shall, within five business days after their receipt of such notice, 
provide written notice of the proposed withdrawal to each remaining 
Certificate Holder who beneficially owns 750 (as adjusted by Section 8.1) or 
more shares of Series A Common (the "Optionee"), which notice shall include 
all the information that the Trustees received.  The withdrawing Certificate 
Holder may require the Optionees exercising the options hereinafter described 
to acquire the shares of Series A Common proposed to be converted and 
withdrawn by an exchange of Common Stock in lieu of a cash purchase.  Any 
such requirement shall be set forth in the withdrawal request.

     (b) EXERCISE OF FIRST OPTION. Each Optionee shall have the option,
exercisable until thirty days prior to the specified date of withdrawal (sixty
days in the case of a withdrawal requiring more than ninety days' notice), to
elect to acquire his or her proportionate part (as hereinafter defined) of the
shares of Series A Common proposed to be converted and withdrawn.  Such
acquisition may be by cash purchase or by exchange of Common Stock.  The notice
of intent to exercise such option shall be delivered to the Trustees not less
than thirty days prior to the specified date of withdrawal (sixty days in the
case of a withdrawal requiring more than ninety days' notice).  The closing 

                                       -14-



date of such transaction shall be the specified date of withdrawal.  An 
Optionee's proportionate part pursuant to this option shall be that number of 
shares which bears the same proportion to the total number of shares proposed 
to be withdrawn as the number of votes beneficially held by such Optionee at 
the time the notice of intent to withdraw is given bears to the total number 
of votes then beneficially held by all Optionees.  An Optionee may elect to 
acquire less than his or her proportionate part of the shares proposed to be 
withdrawn.

     (c)  NOTICE AND EXERCISE OF SECOND OPTION. In the event all of the 
shares proposed to be withdrawn are not acquired pursuant to the first 
option, each Optionee shall be notified within five days after the last date 
to exercise such option that he or she has a second option exercisable until 
twenty days prior to the specified date of withdrawal (forty days in the case 
of withdrawal requiring more than ninety days' notice).  Such second option 
shall entitle each Optionee to acquire his or her proportionate part of the 
shares of Series A Common not being acquired pursuant to the first option.   
Such proportionate part shall be that number of shares which bears the same 
proportion to the total number of shares not acquired pursuant to the first 
option as the number of votes beneficially held by such Optionee at the time 
the notice of intent to withdraw is given bears to the total number of votes 
then beneficially held by all Optionees.  An 

                                       -15-



Optionee may elect to acquire less than his or her proportionate part 
pursuant to this second option.

     (d) NOTICE AND EXERCISE OF THIRD OPTION.  In the event all of the shares 
of Series A Common proposed to be withdrawn are not acquired pursuant to the 
first and second options, each Optionee shall be notified within five days 
after the last date to exercise the second option that he or she has a third 
option exercisable until ten days prior to the specified date of withdrawal 
(twenty days in the case of a withdrawal requiring more than ninety days' 
notice).  The third option shall entitle each Optionee to acquire part of any 
shares not acquired pursuant to such preceding options.  Each Optionee 
wishing to exercise the third option shall be required to specify the maximum 
number of shares he or she is willing to acquire.  An Optionee may elect to 
acquire less than his or her proportionate part pursuant to this third 
option.  The Trustees shall allocate the unacquired shares so that each such 
Optionee is entitled to acquire the lesser of (i) that number of unacquired 
shares which bears the same proportion to the total number of unacquired 
shares as the number of votes beneficially held by such Optionee at the time 
the notice of intent to withdraw is given bears to the total number of votes 
then beneficially held by all Optionees wishing to exercise the third option, 
and (ii) the number of shares specified by the Optionee pursuant to his or 
her exercise of this third option. 

                                       -16-



The Trustees shall allocate any shares still unacquired so that each Optionee 
having specified a number of shares greater than were allocated to him or her 
pursuant to the preceding allocation is entitled to acquire the lesser of (i) 
that number of remaining unacquired shares which bears the same proportion to 
the total number of unacquired shares as the number of votes beneficially 
held by such Optionee at the time the notice of intent to withdraw is given 
bears to the total number of votes then beneficially held by all Optionees 
who specified a number of shares greater than were allocated to him or her 
pursuant to the preceding allocation, and (ii) the number of shares specified 
by the Optionee pursuant to his or her exercise of this third option but not 
yet allocated to him or her.  The Trustees shall continue to allocate any 
unacquired shares in accordance with the preceding sentence until all shares 
are allocated or until no more shares are specified by the Optionees.

     (e)  ALTERNATE PROCEDURE AND REDUCED NOTICE PERIOD FOR SMALL 
WITHDRAWALS.  Notwithstanding the preceding provisions of this Section 3.2, 
in the event of any notice of intended withdrawal described in Section 3.2(a) 
with respect to 7,500 (as adjusted by Section 8.1) Common Shares or less, 
only the option procedure described in Subsection 3.2(d) shall be used, to be 
extended to all Optionees.  The Trustees may, in their discretion, reduce the 
period required between notice and withdrawal 

                                       -17-



for purposes of Subsection 3.1(b) so long as notice is given to all Optionees 
and each such Optionee is given no less than five days after receipt of such 
notice to respond.  Such reduction shall be approved by a six-vote majority 
of the Trustees; provided, however, that the required six votes shall be 
reduced by the number of votes held by any Trustee who is the Certificate 
Holder desiring a reduction of such period, such Trustee being excluded from 
voting with respect to such matter.  If the date of withdrawal is 
accelerated, the accelerated date of withdrawal shall be used to establish 
the cash price to be paid determined pursuant to Subsection 3.2(f).

     (f) PAYMENT OF ACQUISITION PRICE.  Each Optionee electing to purchase 
shares shall deliver to the Trustees on the closing date either (i) cash for 
each share so purchased in an amount equal to the average closing price of 
the Common Shares of the Company in their primary marketplace on the first 
ten of the most recent eleven business days on which they were traded 
preceding the specified date of withdrawal, (ii) a stock certificate 
representing that number of Common Shares equal to the number of shares so 
purchased (and such stock certificate may have been previously deposited 
hereunder, in which case no delivery shall be required, but the Optionee 
shall direct the Trustees to use such shares in the exercise of such option), 
or (iii) a combination of (i) and (ii).  To the extent the withdrawing 
Certif-

                                       -18-



icate Holder requires that the acquisition be made by an exchange of Common 
Shares, each Optionee must deposit that number of Common Shares which bears 
the same proportion to the total number of Common Shares so required as the 
number of shares to be acquired by such Optionee bears to the total number of 
shares to be acquired by all Optionees, except to the extent the Optionees 
may agree to otherwise apportion the requirement to tender Common Shares.

     (g) WITHDRAWAL OF UNACQUIRED SHARES.  To the extent any shares are 
not acquired pursuant to the preceding provisions of this Section 3.2, the 
Certificate Holder who intends to withdraw Common Shares may do so, free of 
the terms of this Agreement, as provided in Section 3.3.

     (h) ACQUIRED SHARES TO REMAIN SUBJECT TO AGREEMENT.  Any 
Certificate Holder acquiring shares of Series A Common pursuant to the 
exercise of the option granted under this Section 3.2 shall be deemed to have 
simultaneously deposited such shares with the Trustees, which shares shall 
remain subject to this Agreement, and shall be issued a Voting Trust 
Certificate or Certificates as provided in Section 2.1.

                                       -19



     (i) OPTION RIGHTS DO NOT APPLY TO SALE BY TRUSTEES.  The provisions of 
this Section 3.2 do not apply to a sale by the Trustees pursuant to 
Subsection 6.4(a).

     3.3 REQUEST FOR REGISTRATION.  With respect to any withdrawal  of Common 
Shares pursuant to Subsection 3.2(g) or the withdrawal of Common Shares 
delivered by an Optionee pursuant to the exercise of an option, the 
Certificate Holder making such withdrawal shall, not less than five business 
days prior to the date on which the Common Shares are to be withdrawn, 
deliver to the Trustees and to any transfer agent for the Common shares 
appointed by the Company (the "Transfer Agent"), a request, in customary 
form, setting forth the denominations in which stock certificates for the 
Common Shares are to be delivered and the names in which such stock 
certificates are to be registered.  A similar request shall be made by an 
Optionee with respect to the registration of any Voting Trust Certificates 
issued pursuant to Subsection 3.2(h). To the extent such requests are not 
made, the Trustees shall issue a single stock certificate in the name of the 
withdrawing Certificate Holder for all shares to be withdrawn or a single 
Voting Trust Certificate in the name of the Optionee representing all 
beneficially-owned shares acquired the exercise of an option.

                                       -20-



     3.4  CONVERSION.  The Trustees shall not convert any shares of Series A 
Common deposited hereunder except in conjunction with a withdrawal of shares 
permitted by this Article III.

     3.5  ESTABLISHMENT OF PRICE IF COMPANY SHARES NOT TRADED.  If a value 
for withdrawn shares cannot be established for purposes of Subsection 3.2(f) 
because the Company's Common Shares are no longer traded in a public 
marketplace or because no trading has occurred on any of the first ten of the 
most recent eleven business days preceding the specified date of withdrawal, 
such value shall be established pursuant to such reasonable procedures as the 
Trustees may from time to time establish, including, without limitation, the 
securing of one or more appraisals or the use of prices at which the 
Company's Common Shares were sold prior to the said ten-day period or in 
non-public transactions.

                                       -30-

vested in a natural person who is either a Certificate Holder or a

Permitted Transferee of a Certificate Holder.  No such person vested with

     4.4  TRANSFERS.  Subject to the foregoing Sections 4.1 and 4.2, the 
Voting Trust Certificates shall be transferable on the books of the Trustees 
by the holders of record thereof in person or by duly authorized attorney, 
subject to such regulations as may be established by the Trustees for that 
purpose, upon surrender thereof at the office of the Trustees, properly 
endorsed for transfer, and the Trustees may treat the holders of record 
thereof, or when duly endorsed in blank the bearers thereof (so long as such 
bearers are Permitted Transferees), as the owners of Voting Trust 
Certificates for all purposes whatsoever.  As a condition of making or 
permitting any transfer or delivery of stock certificates or Voting Trust 
Certificates, the Trustees may require the payment of a sum sufficient to pay 
or reimburse them for any stamp tax or other governmental charge in 
connection therewith or any other charge applicable to such transfer or 
delivery.

     4.5  TRANSFEREES BOUND BY AGREEMENT.  Every Permitted Transferee of 
Voting Trust Certificates shall, with respect thereto 


                                       -31-


and by the acceptance thereof, become a party hereto with like force and 
effect as though an original party hereto and shall be embraced within the 
meaning of the terms "Depositing Shareholder" or "Certificate Holder" 
wherever used herein; provided, however, that no such Permitted Transferee 
shall be required to deposit any certificates representing shares of Series A 
Common which he or she may otherwise own and which are not Subsequent Voting 
Trust Certificates.

     4.6  RECORD DATE.  The Trustees, in their discretion, may fix a record 
date as of which the Certificate Holders entitled to any payment or to take 
any action may be determined.  Any record date fixed by the Company with 
respect to any payment shall be deemed to have been fixed by the Trustees as 
the record date for the purpose of determining the Certificate Holders 
entitled to such payment.  Any other record date fixed by the Company shall 
be deemed to have been fixed by the Trustees unless the Trustees, within ten 
days after the fixing of such record date by the Company, fix and notify the 
Certificate Holders of a different record date.  The Certificate Holders at 
the close of business on any such record date shall be deemed to be the 
persons so determined.

                                      ARTICLE V

                                      DIVIDENDS

     5.1  TRUSTEES TO PASS THROUGH CASH DIVIDENDS.  Each Certificate Holder 
shall be entitled during the life of this Voting Trust, except as may be 
otherwise provided herein, to receive from time to time payments equal to the 
dividends payable in money, if any, received by the Trustees on a number of 
shares of Series A Common equal to that represented by such Voting Trust 
Certificate.

     5.2  DIRECT PAYMENT OF DIVIDENDS.  The Trustees, instead of themselves 
receiving and disbursing dividends, may request the Company to pay the amount 
of any dividends upon the shares of Series A Common held by such Trustees 
hereunder to which such Trustees from time to time become entitled directly 
to the Certificate Holders after deducting any charges and expenses 
authorized herein and any income or other taxes required by law to be 
deducted therefrom; payments in respect of each such dividend shall be made 
according to their respective interests to the Certificate Holders registered 
as such at the close of business on the record date determined pursuant to 
Section 4.6; provided, however, that the Trustees may at any time or from 
time to time thereafter request the Company to make payment in respect of 
such dividends to the Trustees.


                                       -33-


     5.3  HOLD ON DIVIDENDS AT TERMINATION.  At the termination of this 
Agreement the Trustees may continue to hold the shares of Series A Common 
represented by any Voting Trust Certificate issued and outstanding under this 
Agreement and any dividend received on such shares of Series A Common until 
the surrender of such Voting Trust Certificate by the holder thereof.

     5.4  STOCK DIVIDENDS, STOCK SPLITS AND RECAPITALIZATIONS.  Except as 
provided in Section 5.6, in the event the Trustees shall receive any 
fully-paid shares of Series A Common as a result of a dividend, stock split, 
recapitalization or other distribution in respect of the shares of Series A 
Common held hereunder, the Trustees shall hold such shares subject to this 
Agreement and shall issue Voting Trust Certificates, in proportion to their 
respective interests, to the Certificate Holders of record at the close of 
business on the date fixed by the Company as the record date for the 
determination of the shareholders entitled to receive distributions in 
respect of such dividend or split.

     5.5  OTHER FORMS OF DIVIDENDS.  Except as otherwise provided in Sections 
5.4 and 5.6, if any dividend or other distribution in respect of the shares 
of Series A Common held by the Trustees hereunder shall be paid otherwise 
than in cash, the Trustees 


                                       -34-


shall distribute the same in kind ratably among the Certificate Holders 
entitled to receive such dividend or other distribution upon payment by each 
Certificate Holder of a sum sufficient to reimburse the Voting Trustees for 
any stamp tax, other governmental charge or other expense which the Voting 
Trustees shall have incurred, or for which they shall have or will become 
liable in connection therewith.

     5.6  RECEIPT OF VOTING SECURITIES OF SEPARATE ENTITY.  If, as the result 
of a merger, reorganization, spin-off, dissolution or other transaction, the 
Trustees receive any voting securities or property convertible into voting 
securities of any other entity, the Trustees shall retain such securities and 
property, holding and administering such securities and property pursuant to 
this Agreement.  If the Trustees hold voting securities of two or more 
separate entities as a result of any of the transactions referred to in the 
preceding sentence, and if such securities or property provide the Trustees 
with more than ten percent (10%) of the voting power required to elect a 
majority of the board of directors of an entity other than the Company, the 
Trustees are hereby authorized and directed to create an additional trust or 
trusts identical to the trust created pursuant to this Agreement, having the 
same Trustees, such that the voting securities of each separate entity 
(including any property convertible into such voting securities) are held 
pursuant to the terms of a separate 


                                       -35-



trust.  Any such additional trust must be ratified by no less than sixty-five 
percent (65%) in interest of the Certificate Holders who elect to exercise 
their right to vote pursuant to Section 5.6 before becoming effective. If 
such voting trust is not established, the Trustees shall distribute any such 
securities and property in accordance with Section 5.5.

     5.7  SUBSCRIPTION OFFER.

          (a)  MANNER OF EXERCISE OF SUBSCRIPTION RIGHTS.  In the event any 
securities of the Company shall be offered for subscription to the holders 
of the shares of Series A Common, the Trustees, promptly upon receipt of 
notice of such offer, shall mail a copy of such notice to each Certificate 
Holder with a notice of the number of shares subscribable with respect to 
such Certificate Holder's beneficially-owned shares of Series A Common.  Upon 
receipt by the Trustees, within such time as shall be fixed by the Trustees 
prior to the last date fixed by the Company for subscription and payment, of 
a request from any Certificate Holder to subscribe in his or her behalf and 
of the amount of money required to pay for a specified amount of such 
securities (not in excess of the amount of such securities subscribable in 
respect of such holder's beneficially-owned shares of Series A Common), the 
Trustees shall make such subscription and payment.  Upon receiving from the 
Company the certificate for 


                                       -36-


the securities so subscribed for, the Trustees, if such securities be Series 
A Common having voting rights greater than those held by Common Shares, shall 
hold the same under this Agreement and shall issue to such holder a Voting 
Trust Certificate in respect thereof; and if such securities be other 
securities the Trustees may in their discretion hold such securities under 
this Agreement and shall issue to such holder a Voting Trust Certificate in 
respect thereof or may deliver the certificates for such other securities to 
such holder.  In the event securities of a subsidiary of the Company shall be 
offered for subscription to the holders of the shares of Series A Common, the 
receipt of any voting securities or other property convertible into voting 
securities of such subsidiary shall be treated as a receipt to which the 
provisions of Section 5.6 apply.

          (b)  TRANSFER OR WITHDRAWAL OF SUBSCRIPTION RIGHTS.  The rights of 
any Certificate Holder to subscribe to additional shares of Series A Common 
as provided in Subsection 5.7(a) may be transferred only in accordance with 
the provisions of Article IV and may be withdrawn only in accordance with the 
provisions of Article III, except that the Trustees shall establish shorter 
time periods pursuant to Section 3.2 if reasonably necessary to deal with the 
terms of the subscription offer, and shall give reasonable notice of such 
change.


                                       -37-


          (c)  SERIES A COMMON ACQUIRED PURSUANT TO SUBSCRIPTION RIGHT BY 
TRANSFEREE.  Any shares of Series A Common acquired pursuant to subscription 
rights assigned to a transferee shall be held by the Trustees subject to all 
the terms and conditions of this Agreement.

                                     ARTICLE VI
                                          
                                   VOTING RIGHTS
                                          

     6.1  TRUSTEES TO VOTE SHARES.  Until the actual delivery to the 
Certificate Holder by or on behalf of the Trustees of a certificate issued by 
the Company representing the shares of Series A Common deposited hereunder in 
exchange for said Voting Trust Certificates, pursuant to the provisions 
hereof, the Trustees shall possess and shall be entitled to exercise all the 
rights and powers of owners of the shares of Series A Common of the Company 
deposited hereunder, to vote for every purpose and to consent to any and all 
corporate acts of the Company, it being expressly stipulated that no right to 
vote or to consent or to be consulted in respect to any such shares of Series 
A Common is created in or passes to any Certificate Holder by or under any 
Voting Trust Certificate, or by or under this Agreement, or by or under any 
other agreement, express or implied, except as provided in Sections 6.3 and 
6.4.


                                       -38-


     6.2  SERIES A COMMON TO BE VOTED AS A UNIT.  Except as provided in 
Sections 6.3 and 6.4, the Trustees shall vote the shares of Series A Common 
held by them or take any other action with respect to such shares of Series A 
Common as a unit in accordance with the determination of the six-vote 
majority of the Trustees.

     6.3  FAILURE TO ACHIEVE A SIX-VOTE MAJORITY.  Except as otherwise 
provided in Section 6.4, in the event of the failure of the Trustees to 
achieve a six-vote majority with respect to the exercise of the right to vote 
the Series A Common on any proposal, the Trustees shall promptly notify all 
Certificate Holders of record and the Trustees shall vote all shares of 
Series A Common deposited hereunder with respect to each such proposal as 
more than fifty percent (50%) in interest of the Certificate Holders who 
elect to exercise their right to vote pursuant to this Section 6.3 shall 
direct in writing.

     6.4  CERTAIN TRANSACTIONS TO REQUIRE JOINT CONSENT OF TRUSTEES  AND 
CERTIFICATE HOLDERS.

          (a)  (i)  Upon any proposal for the sale of shares of Series A 
Common by the Trustees;


                                       -39-


              (ii)  Upon any proposal submitted for shareholder approval for:

                    (1)  the merger or consolidation of the Company with or into
any other corporation, or the merger or consolidation of any other corporation
with or into the Company;

                    (2)  the sale, lease, exchange, mortgage or pledge of all,
or substantially all, the property and assets of the Company;

                    (3)  the sale, exchange or other disposition of a 
significant subsidiary of the Company or of the voting control of such 
subsidiary (meaning, for purposes of this Section 6.4, a subsidiary whose 
fair market value, as estimated in the reasonable judgment of the Trustees, 
equals or exceeds twenty-five percent (25%) of the fair market value of the 
Company and all of its subsidiaries, similarly determined);

                    (4)  the merger or consolidation of a significant 
subsidiary of the Company with or into any other corporation, or the merger 
or consolidation of any other corporation with or into a significant 
subsidiary of the Company in a transaction which would leave the Company with 
fifty percent (50%) or less of the voting power of such significant 
subsidiary;


                                       -40-


                    (5)  the sale, lease, exchange, mortgage or pledge of 
all, or substantially all, the property and assets of a significant 
subsidiary of the Company;

                    (6)  the dissolution, winding up or liquidation of the
Company or its business or of a significant subsidiary of the Company or of its
business;

                    (7)  the amendment of the Company's Articles of
Incorporation; or

                    (8)  the issuance of any securities having voting rights
superior to those of Common Shares;


             (iii)  Upon any proposal for any other transaction not 
previously described in this Section 6.4 which would be deemed a change of 
control under the rules and regulations of either the Securities and Exchange 
Commission or the Federal Communications Commission;

the Trustees shall promptly notify all Certificate Holders and the Trustees 
shall not approve or implement any such action and shall not vote any shares 
of Series A Common in favor of any such proposal unless (1) the Trustees 
receive the written direction in 


                                       -41-


favor of the proposal from no less than seventy-five percent (75%) in 
interest of the Certificate Holders of record, and (2) a six-vote majority of 
the Trustees concur at a meeting of the Trustees.  In the absence of both 
conditions (1) and (2) being satisfied, the Trustees shall, as the case may 
be, refrain from the sale of shares of Series A Common, vote against any 
proposal which would have the effect of approving any transaction described 
in Subsections 6.4(a)(ii)(1) through (8), or shall refrain from approving or 
implementing any proposal described in Subsection 6.4(a)(iii); provided, 
however, that the rights of each dissenting Certificate Holder shall be 
safeguarded as provided in Subsection 6.4(b)

          (b)  With respect to any Certificate Holder who files a written 
direction opposing a proposal referred to in Subsection 6.4(a) (a "dissenting 
Certificate Holder"):

               (i)  No shares of Series A Common held by the Trustees for the 
benefit of such dissenting Certificate Holder shall be sold without the 
express written consent of such Certificate Holder.  If all shares of Series 
A Common except those held for the benefit of dissenting Certificate Holders 
are being sold, the Trustees shall distribute the shares not being sold to 
such dissenting Certificate Holders on the date the balance of the Series A 
Common is sold.


                                       -42-


              (ii)  In the event of a transaction in which the law of the 
state of incorporation of the Company grants a dissenting shareholder 
appraisal rights, the Trustees shall, in accordance with and to the extent 
permitted by law, take such reasonable steps as are directed in writing by 
each dissenting Certificate Holder to perfect such dissenting Certificate 
Holder's appraisal rights with respect to his or her beneficially owned 
shares of Series A Common, the costs of which shall be borne by each such 
dissenting Certificate Holder in accordance with the reasonable allocation of 
such cost by the Trustees.  To the extent the Trustees are not legally 
permitted to fully perfect such rights, the Trustees shall distribute such 
shares to their beneficial owners so that they may individually take the 
necessary steps to perfect such rights.

          (c)  Notwithstanding any provision of this Agreement to the 
contrary, with respect to the sale of shares of Series A Common held by the 
Trustees pursuant to this Agreement:

               (i)  no such sale shall be made by the Trustees unless the 
proceeds of such sale shall benefit all of the non-dissenting Certificate 
Holders proportionately to their beneficial ownership of each class of 
securities comprising the Series A Common hereunder;


                                       -43-


              (ii)  no Trustee shall negotiate or consider any offer with 
respect to such sale without notice to all Trustees;

             (iii)  except with the consent of a six-vote majority of the 
Trustees, no Trustee shall enter into any arrangement which commits the 
Trustee to vote either in his or her capacity as a Trustee or as a 
Certificate Holder in any specific manner; and

              (iv)  the Trustees shall give reasonable consideration to any 
offer to purchase all or a portion of such shares which may be made by any 
one or more Certificate Holders representing five percent (5%) or more in 
interest hereunder, provided that the Trustees shall not be required to give 
any additional notice to such Certificate Holders other than the notice 
required pursuant to Subsection 6.4(a), nor shall the Trustees be required to 
grant any additional time to such Certificate Holders in which to present 
such offer.

     6.5  VOTING RIGHTS OF CERTIFICATE HOLDERS.  

          (a)  The voting rights available to any Certificate Holder pursuant 
to Sections 6.3, 6.4 or 7.3:


                                       -44-


               (i)  may be exercised in person;

              (ii)  may be exercised by proxy, provided that the holder of such
proxy must be another Certificate Holder or the Permitted Transferee of any
Certificate Holder and provided the proxy is executed within one year before the
date on which it is exercised;

             (iii)  may be exercised by written ballot with respect to any 
matter placed before the Certificate Holders in a proxy statement or other 
written notice from the Trustees, in such form and subject to such time 
limits as the Trustees may reasonably require;

              (iv)  may be assigned to a voting trust as provided in 
Subsection 4.2(a)(iii); provided that each voting trustee thereof shall be a 
Certificate Holder or the Permitted  Transferee of a Certificate Holder.

          (b)  Whenever a percentage in interest of the Certificate Holders 
is required with respect to any matter, it shall mean that percentage of the 
votes of all Certificate Holders eligible to vote after giving effect to the 
provisions of Section 


                                       -45-


4.3, except as otherwise provided for purposes of Sections 5.6 and 6.3.

          (c)  A Certificate Holder may cast one vote for each vote to which 
his or her beneficially-owned shares of Series A Common is entitled with 
respect to the Company's affairs.

                                    ARTICLE VII
                                          
                                    THE TRUSTEES
                                          

     7.1  MEETINGS AND PROCEDURES.


          (a)  ANNUAL MEETINGS.  The Trustees shall meet annually on the 
first Saturday in April in Chicago, Illinois, or at such other time and place 
as they may otherwise determine, with such reasonable notice as their rules 
may provide, including notice to all Certificate Holders who shall be invited 
to attend each such annual meeting.

          (b)  OTHER MEETINGS OF THE TRUSTEES.  In addition to the annual 
meetings, the Trustees may meet at such time and place as they may determine, 
with such reasonable notice as their rules may provide (and such rules shall 
provide that any two trustees may call such a meeting).


                                       -46-



          (c)  MEETING PROCEDURES.  Except for actions required of the 
Trustees pursuant to Subsection 6.4(a), the Trustees may act without a 
meeting by a writing embodying their action executed by that number of 
Trustees holding the votes necessary to approve such action if there had been 
a meeting, with notice to each Trustee not executing such writing.  The 
Trustees shall adopt their own rules of procedure.  At any meeting of the 
Trustees any Trustee may vote in person or by proxy given to any other 
Trustee, and any Trustee may give powers of attorney to any other Trustee to 
sign any instrument expressing the actions of the Trustees.  Trustees may 
participate in any meeting by means of conference telephone or similar 
communications equipment by means of which all persons participating in the 
meeting can hear each other, and such participation in a meeting shall 
constitute presence in person at the meeting.  The Trustees may vote by proxy 
at any meeting of the Company, if they so elect, provided that such proxy be 
signed by at least those Trustees holding no fewer than six votes.

          (d)  SPECIAL MEETINGS.  Special meetings of the Certificate 
Holders and the Trustees, for any purpose or purposes, may be called by  any 
two Trustees.  Written notice of a special meeting, stating the place, date 
and hour of the meeting and the purpose or purposes for which the meeting is 
called, signed by 


                                       -47-


two or more Trustees, shall be given not less than ten nor more than sixty 
days before the date of the meeting to each Certificate Holder entitled to 
vote at such meeting, with an information copy to any Certificate Holder not 
entitled to vote at the meeting by reason of the provisions of Section 4.3.

     7.2  VOTING OF TRUSTEES.

          (a)  TRUSTEES' VOTING POWER.  The "Johnson Family Trustee" (as 
defined in Section 7.5) shall have one vote.   All other Trustees acting 
hereunder shall each have two votes.

          (b)  TYPES OF MAJORITIES.  A "six-vote majority" shall require the 
affirmative vote by Trustees holding no fewer than six votes.  An "eight-vote 
majority" shall require the affirmative vote by Trustees holding no fewer 
than eight votes.  Any action requiring the approval of the Trustees for 
which no reference is made to either of the aforesaid majorities shall 
require a six-vote majority.  The number of votes required shall not be 
reduced by reason of  the temporary vacancy of any trusteeship, by the 
failure of any Trustee to be present at a meeting of the Trustees either in 
person or by proxy, by the cessation of the Johnson Family Trustee or for any 
other reason except as specifically set forth in Subsections 3.1(h), 3.1(i) 
or 3.2(e).


                                       -48-


          (c)  EFFECT OF FAILURE TO ACHIEVE REQUIRED MAJORITY.  In the event 
of the failure of the Trustees to achieve the required six-vote or eight-vote 
majority as to any proposal not described in Section 6.3 (i.e., a proposal 
not involving the right to vote the Series A Common), such proposal shall 
fail.

          (d)  AUTHORITY OF ACTING AND SUCCESSOR TRUSTEES.  Pending the 
election of a successor Trustee to fill any vacancy, the Trustees then acting 
shall possess and may exercise all the powers of the Trustees hereunder, 
provided they retain a sufficient number of votes to fulfill the applicable 
six-vote or eight-vote majorities.

     7.3  ELECTION OF TRUSTEES.


          (a)  TERMS OF OFFICE.  The Trustees named or elected hereunder 
shall serve terms of offices, as follows:

     First Term:    The effective date hereof  - June 30, 1994

     Second Term:   July 1, 1994               - June 30, 1999

     Third Term:    July 1, 1999               - June 30, 2004

     Fourth Term:   July 1, 2004               - June 30, 2009


          (b)  REGULAR ELECTION.  No less than sixty days prior to the 
expiration of a term of office, the Trustees shall hold an 


                                       -49-


election among the Certificate Holders to elect a new slate of Trustees.  
Each Certificate Holder shall have the right to vote, in person or by proxy, 
the number of votes he or she beneficially holds for as many persons as there 
are Trustees to be elected, or to accumulate such votes and give one 
candidate up to that number of votes determined by multiplying the number of 
Trustees to be elected by the number of shares of Series A Common he or she 
beneficially owns, or to distribute such votes on the same principle among as 
many candidates as such Certificate Holder shall think fit.  The candidates 
receiving the highest number of votes up to the total number of Trustees to 
be elected shall be elected.

          (c)  SPECIAL ELECTION.  If one or more vacancies should occur 
during a term by reason of death, disability, resignation or removal, the 
Trustees shall, within sixty days of any vacancy, promptly hold a separate 
special election to elect each successor Trustee to complete the remainder of 
a term.  Only those Voting Trust Certificates with respect to which votes 
were cast in favor of the Trustee who has died, become disabled, resigned or 
been removed may be cast with respect to the election of the successor 
Trustee.  If the Trustee who has died, become disabled, resigned or been 
removed is an initial Trustee, only those Voting Trust Certificates deposited 
hereunder by such initial Trustee, either in his or her personal or fiduciary 
capacity, may be cast with 


                                       -50-


respect to the election of the successor Trustee, 
including any such Voting Trust Certificates then held by a Permitted 
Transferee who, even after the application of Section 4.3, is entitled to 
vote hereunder.  The identification of those Voting Trust Certificates shall 
be made by the Trustees as they may reasonably determine.

          (d)  SUCCESSOR TRUSTEES.  Any successor Trustee elected hereunder 
shall be a natural person who is a Certificate Holder or a Permitted 
Transferee of a Certificate Holder.

          (e)  TERMS FOLLOWING RENEWAL.  Should this trust be renewed 
pursuant to Section 8.6, the Trustees serving during the last term shall 
serve until September 30 of the first year of the renewal term.  All 
subsequent terms shall be for five years beginning October 1, except any 
Trustees serving at the termination of this trust because it is not renewed 
pursuant to Section 8.7 shall serve four years and nine months.

     7.4  REMOVAL OF TRUSTEES.  Any Trustee may be removed at any time by an 
instrument signed by no less than eighty-five percent (85%) in interest of 
the Certificate Holders of record and delivered to the Trustees, such removal 
to occur upon receipt of such instrument.  Any Trustee shall be automatically 
removed at such time as the Trustees shall have knowledge of any law or 

                                  -51-



regulation to which the Company or this trust is subject which, because of 
the Trustee's status as an alien or because of the Trustee's criminal record, 
the Company would be denied the right to provide a material service which it 
could have otherwise provided consistent with its normal business practices.  
Upon the removal of any Trustee, the remaining Trustees shall, within sixty 
days, hold an election as provided in Section 7.3.

     7.5  JOHNSON FAMILY TRUSTEE.  Notwithstanding the provisions of Sections 
7.3 and 7.4:

          (a)  So long as Lester O. Johnson and his Family Members, together 
with any fiduciary of a Charitable Organization, trust, estate or qualified 
retirement plan who is a Permitted Transferee of any such person and who, 
after giving effect to the provisions of Section 4.3, is entitled to vote 
hereunder, (the "Johnson Family"), hold the percentage in interest required 
by Subsection 7.5(c), the following provisions shall apply:

               (i)  the Trustee's position held by Melanie J. Heald or any 
successor elected in her place shall be known as the "Johnson Family Trustee;"

              (ii)  the terms of the Johnson Family Trustee shall be 
concurrent with the terms of the other Trustees, and a

                                   -52-



new Johnson Family Trustee shall be elected at the same time the other 
Trustees are elected; except such election shall be made by the majority in 
interest of the Johnson Family Certificate Holders of record subject to the 
approval of the remaining Trustees as provided in Subsection 7.5(a)(v);

             (iii)  the Johnson Family Trustee may be removed only by a 
majority in interest of the Johnson Family Certificate Holders of record;

              (iv)  if the Johnson Family Trustee should become unable to act 
by reason of death, disability, resignation or removal, a successor Trustee 
shall be elected by a majority in interest of the Johnson Family Certificate 
Holders of record, subject to the approval of the remaining Trustees as 
provided in Subsection 7.5(a)(v) and;

               (v)  any successor Johnson Family Trustee shall give notice of 
his or her election to the remaining Trustees and shall be deemed approved 
(1) upon the consent of a six-vote majority or (2) upon the expiration of ten 
days from such notice unless four votes of the remaining Trustees have been 
cast against the approval of such successor Trustee;

                                    -53-



          (b)  So long as the Johnson Family Trust is acting, the Johnson 
Family Certificate Holders shall not be entitled to vote with respect to the 
election or removal of any other Trustee, and all references to the election 
or removal of the Trustees shall refer only to the four Trustees other than 
the Johnson Family Trustee and all references to the Certificate Holders 
entitled to participate in the election or removal of any other Trustees 
hereunder shall be a reference only to the Certificate Holders other than the 
Johnson Family Certificate Holders.

          (c)  Six months after the date on which the percentage in interest 
of the Johnson Family falls below (i) six percent (6%) at any time either or 
both of Lester O. Johnson and Frances M. Johnson are living or (ii) five 
percent (5%) following the death of the survivor of Lester O. Johnson and 
Frances M. Johnson, the Johnson Family Trustee shall cease to be a Voting 
Trustee and thereafter there shall be only four such Trustees; provided, 
however, if at any time during the one-year period following the expiration 
of the aforesaid six-month period the percentage in interest of the Johnson 
Family should be in excess of the applicable percentage test, the Johnson 
Family Trustee shall resume office subject to all of the provisions of this 
Agreement including the provisions of this Subsection 7.5(c).

                                     -54-



     7.6  RESIGNATION OF TRUSTEES.  Any of the Trustees may at any time 
resign, and thereby be relieved of all future obligations to act hereunder, 
by mailing his or her resignation to the Certificate Holders at their 
respective addresses appearing on the Trustee's records.  Such resignation 
shall be deemed effective immediately upon its being mailed.

     7.7  CHANGE OF CONTROL.  Any change of trustees hereunder which 
constitutes a change of control which requires prior Federal Communications 
Commission approval shall not be effective until such approval is obtained.

     7.8  REIMBURSEMENT OF EXPENSES.  The Trustees may employ counsel or a 
depositary and incur other indebtedness or expenses deemed necessary by them 
for the proper discharge of their duties.  In the discretion of the Trustees, 
by a six-vote majority, any such expenses or discharge of indebtedness may be 
invoiced among all Certificate Holders holding certificates representing 
7,500 (as adjusted by Section 8.1) or more shares of Series A Common, to be 
paid by such Certificate Holders in proportion to their respective beneficial 
ownership of Series A Common.  To the extent any such invoice is not paid 
within sixty days, the Trustees shall be entitled to deduct any such amount 
from the dividends received or receivable by the Trustees with respect to the 
shares of Series A Common beneficially owned by

                                     -55-



the non-paying Certificate Holder before paying or causing such dividends to 
be paid to such Certificate Holder.

     7.9  OTHER RELATIONSHIPS BETWEEN TRUSTEES AND COMPANY.  Any Trustee 
shall be permitted to be, at the same time, an officer, director, consultant, 
agent, or employee of the Company or of any affiliate of the Company, and 
shall be permitted to be or become pecuniarily interested in his or her 
personal capacity, either directly or indirectly, in any matter or 
transaction to which the Company or any affiliate may be a party or in which 
the Company or any affiliate may be concerned to the same extent as though he 
or she were not a Trustee.  Any Trustee shall be permitted to receive 
compensation, of whatever character, as is provided by their existing 
contracts, if any, with the Company or its affiliates, with complete 
propriety and without disqualifying themselves to act as Trustees hereunder; 
and upon the expiration of the existing contracts, if any, with the Trustees, 
or sooner by mutual agreement, the Company or its affiliates and such 
Trustees shall be permitted to enter into new contracts which may change 
their compensation.

     7.10 TRUSTEES MAY BE SHAREHOLDERS, CERTIFICATE HOLDERS AND MAY ACQUIRE 
AND DISPOSE OF SHARES.  Any Trustee shall be permitted, for his or her 
personal account or otherwise, subject to all the terms and conditions of 
this Agreement, to either acquire

                                     -56-



from or sell to the Company or any shareholder shares of stock or other 
securities of the Company or Voting Trust Certificates to the same extent as 
though he or she were not a Trustee.  Any Trustee shall be entitled to 
exercise all rights and options conferred upon Certificate Holders under this 
Agreement to the same extent as though he or she were not a Trustee.

     7.11 COMPENSATION OF TRUSTEES.  The Trustees shall not be entitled to 
compensation for their services as Trustees hereunder.

     7.12 LIMITATION OF LIABILITY.  In voting or giving directions for voting 
the shares of Series A Common deposited hereunder or in exercising any 
consent with respect thereto, the Trustees shall exercise their best 
judgment, from time to time, to select suitable directors and in voting or 
giving directions for voting and acting on other matters for shareholders' 
action the Trustees shall exercise like judgment; provided, however, that the 
Trustees assume no responsibility in respect of such management or in respect 
of any action taken by them or taken pursuant to their consent thereto, or 
pursuant to their votes, and no Trustee shall incur or be under any liability 
as the holder of securities of the Company in his or her capacity as Trustee, 
by reason of any error of law or any error in the construction of this 
Agreement or of any matter or thing done or suggested or omitted to be done 

                                    -57-



pursuant to this Agreement, except for his or her intentional misconduct.   
No bond shall be required of any Trustee for the performance of his or her 
services as such.

                                     ARTICLE VIII

                                  GENERAL PROVISIONS

     8.1  ADJUSTMENT FOR STOCK SPLITS.  Wherever under this Agreement a 
provision sets a limitation or requirement of an amount of shares, such 
number shall be adjusted from time to time as necessary to take into account 
any stock splits, stock dividends, issuance of other voting stock with voting 
rights superior to Common shares and other changes in the capital structure 
of the Company, so that such adjusted number bears the same proportion to the 
voting power of the Company held by this trust following such capital change 
as the number immediately prior to adjustment bore to the voting power of the 
Company held by this trust immediately prior to such capital change.

     8.2  SCOPE OF AGREEMENT.  This Agreement and all covenants herein 
contained shall inure to the benefit of and be binding upon the parties 
hereto, their heirs, executors, administrators, successors and assigns.

                                     -58-



     8.3  NOTICES.  Any notice required to be given under this Agreement 
shall be deemed to have been given and received if actually received, such as 
by telephone, telecopier, electronic mail, telegram, hand delivery, or other 
means, and the giver has reasonable evidence or acknowledgment of its 
receipt.  Notice shall also be deemed to have been given if deposited in the 
United States mail in a postpaid wrapper, in which case it shall be deemed to 
have been received on the third business day after the date of such deposit, 
or if deposited with a commercial or government overnight carrier, in which 
case it shall be deemed to be received the first business day after the date 
of such deposit.  The Trustees shall request a return receipt with each 
notice they mail or send by overnight carrier.

          (a)  In the case of a Certificate Holder, such notice shall be 
addressed to such Certificate Holder at his or her last address appearing on 
the records of the Trustees.

          (b)  In the case of a notice to the Trustees by a Certificate 
Holder, such notice shall be given to each of  the Trustees, addressed to 
each Trustee at his or her address of record, as set forth at the end of this 
Agreement or as it may be changed from time to time by written notice to all 
such holders.

                                    -59-



          (c)  In the case of a notice to a Trustee by another Trustee, 
notice shall be addressed to the Trustee at his or her address of record, as 
set forth at the end of this Agreement or and as may be changed from time to 
time by written notice to the remaining Trustees. The Trustees shall use 
their best efforts to transmit to the Certificate Holders, or to cause the 
Company to transmit, all information sent by the Company to the holders of 
Series A Common.

     8.4  RELIANCE BY TRUSTEE.  The Trustees shall be conclusively entitled 
to rely upon any notice or statement received by them from the Company or the 
holders of record of Voting Trust Certificates and believed by them in good 
faith to be genuine and shall act and shall be fully protected in acting in 
accordance therewith.

     8.5  AMENDMENT OF AGREEMENT.  This Agreement and the Certificates issued 
hereunder may be amended upon the consent in writing of an eight-vote 
majority of the Trustees and no less than ninety percent (90%) in interest of 
the Certificate Holders of record; provided, however, that no amendment which 
shall have the effect of extending the time for termination of this Voting 
Trust

                                    -60-



Agreement shall be made without the consent in writing of all of the 
Certificate Holders.

     8.6  TERMINATION.  This Agreement shall be binding upon each of the 
parties executing the same from the date of its execution by such party.  The 
trust created hereunder shall be effective as of the date hereof, and this 
Agreement and the trust created hereunder shall remain in full force and 
effect until January 31, 2009.  This Agreement and the trust created 
hereunder may be terminated at any time with the consent in writing of an 
eight vote majority of the Trustees and by no less than seventy-five (75%) in 
interest of the Certificate Holders of record.

     8.7  RENEWAL.  Not earlier than January 1, 2009, nor later than March 
31, 2009, the Trustees shall notify all Certificate Holders of their right to 
withdraw their shares of Series A Common upon termination of the trust on 
June 30, 2009, without regard to the provisions of Article III.  All 
Certificate Holders shall have until May 15, 2009, to notify the Trustees of 
their preliminary intent to withdraw upon termination.  The Trustees shall 
notify all Certificate Holders in writing before May 31, 2009, as to which 
Certificate Holders have presented such notice.  The Certificate Holders 
shall notify the Trustees of their final election to withdraw upon 
termination on or before June 30, 2009.  Each Certificate Holder shall be 
eligible to make

                                    -61-



a final election to withdraw irrespective of whether or not he or she 
notified the Trustees of a preliminary intent to withdraw.  If, as of the 
close of business on June 30, 2009, fifty percent (50%) or less in interest 
of the Certificate Holders have elected to withdraw, this trust shall be 
automatically renewed for an additional term of the lesser of twenty years or 
the maximum number of years permitted by controlling law.  If more than fifty 
percent (50%) in interest of the Certificate Holders have elected to 
withdraw, a six-vote majority of the Trustees shall be required to renew the 
trust.  If the trust is renewed, it shall be renewed only with respect to 
those Certificate Holders not electing to withdraw.  This renewal provision 
shall be equally applicable at the end of each succeeding renewal term, with 
appropriate changes in dates to reflect the new termination date.

     8.8  DE MINIMIS HOLDINGS.  The Trustees may, in their discretion, 
distribute to any Certificate Holder who beneficially owns less than 150 (as 
adjusted by Section 8.1) shares of Series A Common the shares of Series A 
Common then held by the Trustees for the benefit of such Certificate Holder, 
which distribution shall not be subject to the provisions of Article III.

     8.9  SEVERABILITY OF PROVISIONS.  The invalidity or unenforceability of 
any term or provision of this Agreement shall not affect the validity of the 
remainder hereof.

                                      -62-



     8.10 INTERPRETATION.  

          (a)  TRUSTEE.  The term "Trustee" or "Trustees" wherever used 
herein means the person or persons from time to time acting in such capacity 
pursuant to the provisions of this Agreement.

          (b)  HEREUNDER.  Whenever the word "hereunder" is used in this 
instrument, it shall refer to the entire instrument, not merely to the 
article, section or subsection in which it appears.

          (c)  BUSINESS DAY.  A "business day" shall be any day on which the 
exchange constituting the primary marketplace for the Company's Common Shares 
is open for business or, if such shares are not listed for trading on an 
exchange, any day on which the New York Stock Exchange, or any successor 
exchange, is open for business.

          (d)  GENDER AND NUMBER.  As the context permits, the gender and 
number of words may be interchanged.

          (e)  HEADINGS.  The headings used herein are for convenience only, 
are not part of the article, section or subsection to which they relate, and 
are not to be used in construing the legal intent of this instrument.

                                     -63-



     8.11 CONTROLLING LAW.  All questions concerning the validity and 
administration of this Agreement and the trust created hereunder shall be 
determined under the law of the State of Iowa, except that the Trustees may, 
in their discretion, elect to change the law to be so used to that of the 
state in which the Company is incorporated as such state may change from time 
to time, upon notice to the Certificate Holders.  This Agreement shall be 
subject to the applicable rules and regulations of the Federal Communications 
Commission.

     8.12 CONSTRUCTION OF AGREEMENT.  All questions concerning the 
interpretation or construction of this Agreement shall be determined by a 
six-vote majority of the Trustees, whose decision shall be final and binding 
on all parties.

     8.13 MULTIPLE COUNTERPARTS.  This Agreement may be executed by the 
parties herein, or any of them, in any number of counterparts, with the same 
force and effect as if they had all executed the same instrument.

     8.14 ENTIRE AGREEMENT.  This Agreement (including the exhibits attached 
hereto) contains the entire understanding among the parties hereto with 
respect to the subject matter hereof, and no

                                   -64-



representation, warranty, covenant or condition other than those expressly 
set forth herein shall be of any force or effect.

                               VOTING TRUST CERTIFICATE

No.___________                                    ______Shares of
                                                   Series A Common

                           TELEPHONE AND DATA SYSTEM, INC.

                  Incorporated under the Laws of the State of Iowa

     THIS IS TO CERTIFY THAT, subject to the provisions hereof and of the 
Voting Trust Agreement hereinafter mentioned, on the surrender hereof, 
properly endorsed, _________________________ will be entitled to receive on 
June 30, 2009, or on the earlier termination of the Voting Trust Agreement, 
as therein provided, a stock certificate, expressed to be full-paid and 
non-assessable, for shares of Series A Common, represented by this 
Certificate, of Telephone and Data Systems, Inc. (the "Company"), a 
corporation organized and existing under the laws of the State of Iowa, or 
its successor.  In the event of a withdrawal of Common Shares by the holder 
of this Certificate pursuant to a Withdrawal Request as contemplated by 
Article III of the Voting Trust Agreement, he or she will be entitled to 
receive a stock certificate for the Common Shares so withdrawn under the 
terms and conditions set forth in Article III or cash or a stock certificate 
for Common Shares to the extent the shares of Series A Common are acquired 
pursuant to the option available to certain participants in the Voting Trust 
Agreement.  In the meantime, subject to the 

                                       -72-




provisions of the Voting Trust Agreement, the holder of this Certificate is 
entitled to receive payments equal and of like character to the dividends if 
any, received by the Trustees upon the number of shares of Series A Common 
held by the Trustees for such holder, less such charges and expenses as are 
authorized by the Voting Trust Agreement to be deducted therefrom and less 
any income or other taxes required by law to be deducted therefrom; provided, 
however, such dividends, if received by the Trustees in Series A Common shall 
be payable in Voting Trust Certificates for such stock.  If the Trustees 
shall exercise on behalf of the holder of this Certificate any right to 
subscribe to shares of Series A Common, in accordance with the provisions of 
the Voting Trust Agreement, the Trustees shall issue Voting Trust 
Certificates in respect thereof.

     Until actual delivery of the stock certificates called for hereby 
following the termination of the Voting Trust Agreement (or in the case of 
Common Shares properly withdrawn pursuant to a Withdrawal Request until 
actual delivery of the stock certificates for such withdrawn Common Shares), 
the Trustees, upon the terms and subject to the provisions stated in the 
Voting Trust Agreement, shall possess and shall be entitled to exercise all 
rights and powers of the owners of such Series A Common to vote for every 
purpose and to consent to any and all corporate acts of the Company, except 
as such right is expressly limited by the terms of the Voting Trust 
Agreement; it being expressly stipu-

                                       -73-



lated that except as expressly provided in the Voting Trust Agreement, no 
right to vote such Series A Common and no right to consent or be consulted in 
respect of such Series A Common is created or passes to any holder of this 
Certificate by or under this Certificate or by or under any agreement express 
or implied.

     This Certificate is issued under and pursuant to, and the rights of each 
successive holder hereof are subject to and limited by, the terms and 
provisions of a certain Voting Trust Agreement, dated as of the thirtieth day 
of June, 1989, between certain owners of Series A Common of the Company and 
the Trustees (herein referred to, and as it may be amended from time to time, 
the "Voting Trust Agreement"), one copy of which is on file with Walter C.D. 
Carlson, or any other successor Trustee acting in his place.  Each holder of 
this Certificate by the acceptance hereof assents and agrees to be bound by 
all the provisions of the Voting Trust Agreement.

     This Certificate is not transferable whether by sale, assignment, gift, 
bequest, appointment or otherwise by the holder of record hereof except as 
provided in Article III or Article IV of the Voting Trust Agreement, subject 
to such regulations as may be established by the Trustees for that purpose, 
upon surrender hereof at the office of the Trustees, properly endorsed for 
transfer, and the Trustees may treat the holder of record hereof as the owner 
of this Certificate for all purposes.  Any attempted transfer which is not 
permitted pursuant to the provisions of 


                                       -74-




Article IV shall be void.  Every transferee of this Certificate shall by the 
acceptance hereof become subject to the provisions of this Voting Trust 
Agreement.

     Anyone who acquires this Certificate for value (other than pursuant to 
the Company's dividend reinvestment plan) represents that he or she is 
acquiring this Certificate for his or her own
personal account and not with a view to the transfer of this Certificate or 
of the shares of Series A Common represented by this Certificate to anyone 
other than a Permitted Transferee (as defined in Article IV of the Voting 
Trust Agreement).

     As a condition of making or permitting any transfer or delivery of stock 
certificates or Voting Trust Certificates, the Trustees may require the 
payment of a sum sufficient to pay or reimburse them for any stamp tax or 
other governmental charge in connection therewith, or any other charges 
applicable to such transfer or delivery.

     The Voting Trust Agreement and this Certificate may be amended at any 
time and from time to time in the manner therein provided by the Trustees 
with the consent in writing of the Trustees holding no fewer than eight votes 
and by not less than ninety percent (90%) in interest of the holders of 
record of Voting Trust Certificates; provided, however, that no amendment 
which shall have the effect of extending the time for termination of the 
Voting Trust Agreement shall be made without the consent in writing of all of 
such participants.  The Voting Trust Agree-

                                       -75-



ment and the trust created thereunder may be terminated at any time with the 
consent in writing of the Trustees holding no fewer than eight votes and by 
not less than seventy-five percent (75%) in interest of the holders of record 
of Voting Trust Certificates.

     This Voting Trust Agreement may be renewed for additional terms with 
respect to the holder of this Certificate unless such holder notifies the 
Trustees prior to June 30, 2009 (in response to
a required notice from the Trustees), of his or her election to withdraw.

                                       -76-



      IN WITNESS WHEREOF, the Trustees have executed this Certificate by
