                       UNITED STATES CELLULAR CORPORATION
                         Common Shares, $1.00 par value



         This  Prospectus  relates to Common  Shares,  par value $1.00 per share
("Common Shares"), of United States Cellular Corporation (the "Company"),  which
are  owned by  Telephone  and Data  Systems,  Inc.  ("TDS"),  and may be sold by
Merrill  Lynch,  Pierce,  Fenner  & Smith  Incorporated  ("Merrill  Lynch"),  in
connection with ordinary trading or market-making activities by Merrill Lynch in
Common  Shares  or  Liquid  Yield  Option(TM)  Notes  due  2015  of the  Company
("LYONS"(TM)).  In addition,  at the request of the Company,  the Standby  Share
Deliverer,  initially  Merrill  Lynch,  may agree to deliver such Common Shares,
and/or other Common  Shares,  to which this  Prospectus  also relates,  which it
acquires from other sources, to Holders of LYONs upon conversion thereof.

         Merrill  Lynch  may  obtain  Common  Shares  from  TDS  pursuant  to  a
Securities  Loan Agreement (the  "Securities  Loan  Agreement")  between Merrill
Lynch  and  TDS.  Under  the  Securities  Loan  Agreement,  subject  to  certain
restrictions,  Merrill  Lynch may,  with the agreement of TDS, from time to time
borrow,  return and reborrow Common Shares from TDS. The number of Common Shares
that may be borrowed  under the  Securities  Loan  Agreement at any time may not
exceed 750,000 shares, which number of Common Shares may be reduced from time to
time by TDS.

         The Securities  Loan Agreement was entered into in connection  with the
public  offering  of the LYONs by the  Company  and is  intended  to  facilitate
ordinary trading and  market-making  activity in the LYONs by Merrill Lynch. The
Securities Loan Agreement is also intended to enhance the ability of the Standby
Share Deliverer to deliver Common Shares to Holders of LYONs which are converted
into Common Shares.  The availability of Common Shares under the Securities Loan
Agreement,  if any, at any time is, as described above, not assured and any such
availability  does not  assure  market-making  activity  in the LYONs by Merrill
Lynch.

         Merrill Lynch may from time to time offer Common Shares directly to one
or more purchasers at negotiated prices, at market prices prevailing at the time
of sale or at prices related to such market prices. In addition,  at the request
of the Company,  the Standby Share  Deliverer may agree to deliver Common Shares
to Holders of LYONs which are converted  into Common  Shares.  LYONs acquired by
the Standby Share Deliverer in connection with such conversions or otherwise may
be resold by the Standby Share Deliverer. See "Arrangements with Merrill Lynch."

         The Common Shares are currently  listed on the American  Stock Exchange
under the symbol USM.

         See "Risk  Factors" on page 7 for a discussion of certain  factors that
should be considered by prospective investors in Common Shares.

         "Liquid Yield Option" and "LYONs" are Trademarks of Merrill Lynch & 
Co., Inc.

                                  Risk Factors

         Prospective   purchasers  of  the  securities   offered  hereby  should
carefully consider the factors discussed under "Risk Factors."

                                               Description of LYONs

Original Offering of LYONs       On  June  13,  1995,  the  Company  issued 
                                 $745,000,000  aggregate principal amount at
                                 maturity of LYONs due June 15, 2015.  There
                                 are no periodic interest payments on the LYONs.
                                 Each LYON  was issued at an  Issue  Price of
                                 $306.46  and  a  principal  amount  due  at 
                                 maturity of $1,000.

Yield to Maturity of LYONs       6% per annum (computed on a semi-annual bond
                                 equivalent  basis)  calculated  from June 13, 
                                 1995.

Conversion Rights                Each LYON is convertible, at the option of the 
                                 Holder, at any time on or prior to maturity. 
                                 Upon conversion of a LYON, the Company may 
                                 elect the delivery of Common Shares, at a 
                                 Conversion Rate of 9.475 shares per LYON, or 
                                 cash equal to the market value of the Common 
                                 Shares into which the LYONs are convertible. In
                                 connection with the conversion of any LYON, the
                                 Company may enter into a Common Share Delivery
                                 Arrangement with a Standby Share

                                 Deliverer, 
                                 initially Merrill Lynch, Pierce, Fenner & Smith
                                 Incorporated ("Merrill Lynch"), whereby, upon 
                                 the agreement of the Standby Share Deliverer to
                                 so act in connection with such conversion, it 
                                 will deliver the Common Shares (and any cash 
                                 payment in lieu of a fractional Common Share) 
                                 deliverable to the Holder upon such conversion.
                                 As a result of such a Common Share Delivery 
                                 Arrangement, the converted LYON will not be 
                                 retired or cancelled, but shall remain 
                                 outstanding with the Standby Share Deliverer 
                                 becoming the Holder thereof.  The Conversion 
                                 Rate will not be adjusted for accrued Original 
                                 Issue Discount, but will be subject to 
                                 adjustment upon the occurrence of certain
                                 events affecting the Common Shares. Upon 
                                 conversion, the Holder will not receive any 
                                 cash payment representing accrued Original 
                                 Issue Discount; such accrued Original Issue 
                                 Discount will be deemed paid by the Common
                                 Shares or cash received on conversion unless 
                                 such LYON remains outstanding pursuant to a 
                                 Common Share Delivery Arrangement. See
                                 "Description of LYONs-Conversion Rights." The 
                                 Company's Common Shares have less voting power 
                                 than its Series A Common Shares. The LYONs are 
                                 not convertible into Series A Common Shares, 
                                 which have effective control of the Company.  
                                 As of June 30, 1996, TDS owned over 80% of the 
                                 combined total of the outstanding Common Shares
                                 and Series A Common Shares of the Company and 
                                 controlled approximately 95% of their combined 
                                 voting power.  As a result, TDS was effectively
                                 able to elect all of the Company's seven 
                                 directors.

Subordination                    The LYONs are  subordinated to all existing and
                                 future Senior Indebtedness of the Company.  The
                                 LYONs are also effectively  subordinated to all
                                 liabilities,   including  trade  payables,   of
                                 subsidiaries of the Company.  See  "Description
                                 of LYONs-  Subordination  of  LYONs;  Effect of
                                 Corporate Structure."

Original Issue Discount          Each LYON was offered at an Original Issue 
                                 Discount for United States Federal income tax 
                                 purposes equal to the excess of the principal 
                                 amount at maturity of the LYON over the amount 
                                 of its Issue Price. Prospective purchasers of 
                                 LYONs upon resale hereby should be aware that, 
                                 although there will be no periodic payments of 
                                 interest on the LYONs, accrued Original Issue 
                                 Discount (or a portion thereof) will be 
                                 includable periodically in a Holder's gross 
                                 income for United States Federal income tax 
                                 purposes prior to conversion, redemption, other
                                 disposition or maturity of such Holder's LYONs,
                                 whether or not such LYONs are ultimately 
                                 converted, redeemed, sold (to the Company or
                                 otherwise) or paid at maturity. See "Certain
                                 Tax Aspects."

Sinking Fund                     None.

Optional Redemption              The LYONs are not redeemable by the Company 
                                 prior to June 15, 2000.  Beginning on June 15, 
                                 2000, the LYONs are redeemable for cash at any
                                 time at the option of the Company, in whole or 
                                 in part, at Redemption Prices equal to the 
                                 Issue Price plus accrued Original Issue 
                                 Discount through the date of redemption. See 
                                 "Description of LYONs-Redemption of LYONs
                                 at the Option of the Company."

Purchase at the Option           The Company  will  purchase  LYONs,  at the 
of the Holder.                   option of the Holder,  as of June 15, 2000 (the
                                 "Purchase  Date") for a Purchase Price per LYON
                                 of $411.99 (Issue  Price  plus  accrued   
                                 Original   Issue Discount   through  such  
                                 Purchase  Date).  The Company  may also  elect
                                 to offer to  purchase LYONs, at the option of

                                 Agreement"), which provides that, subject to 
                                 certain restrictions, Merrill Lynch may, with 
                                 the agreement of TDS, from time to time borrow,
                                 return and reborrow from TDS up to 750,000 
                                 Common Shares, which number of Common Shares 
                                 may be reduced from time to time by TDS. The 
                                 Securities Loan Agreement is intended to 
                                 facilitate ordinary trading and market-making 
                                 activity in the LYONs by Merrill Lynch and may 
                                 also be used by Merrill Lynch, as Standby Share
                                 Deliverer, to obtain Common Shares deliverable 
                                 by it in connection with any Common Share 
                                 Delivery Arrangement entered into with the

                                 at any time is, as described above, not assured
                                 and any  such   availability   does  not
                                 assure market-making activity in the LYONs   by
                                 Merrill  Lynch.  This Prospectus  may be used  
                                 by  Merrill Lynch in connection with the sale 
                                 of Common  Shares  borrowed  by Merrill Lynch 
                                 from TDS under the  Securities Loan Agreement.

                                 Merrill  Lynch is not under any  obligation  to

                                  RISK FACTORS

         Prior to deciding to invest in the securities offered hereby, potential
investors should carefully consider the following  factors,  together with other
information  contained  or  incorporated  by reference  in this  Prospectus,  in
evaluating the Company and its business.

Operating and Financial Performance

         The  Company  is  currently  profitable  but  has  previously  incurred
significant  start-up  costs  and  operating  losses.  The  Company  anticipates
increasing   growth  in  cellular  units  in  service  and  revenues  as  market
penetration  increases  and  as  it  continues  its  expansion  and  development
programs. Marketing and system operations expenses associated with expansion may
reduce the rate of growth in operating cash flow and operating  income from what
would  otherwise be  reported.  In addition,  the Company  anticipates  that the
seasonality of revenue  streams and operating  expenses may affect the Company's
operating and net results from quarter to quarter.

         While  there are  numerous  cellular  systems  operating  in the United
States and other countries,  the industry has only a limited operating  history.
While the Company is  currently  profitable,  changes in any of several  factors
could  reduce the  Company's  growth in operating  income and net income.  These
factors  include:  (i) the growth rate in the Company's  customer base; (ii) the
usage and pricing of cellular  services;  (iii) the churn rate; (iv) the cost of
providing cellular services, including the cost of attracting new customers; (v)
the  introduction of competition from PCS and other emerging  technologies;  and
(vi) continuing  technological advances which may provide additional competitive
alternatives to cellular service.

Competition and New Technologies

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

         In Addition the FCC has  allocated  three 30 MHz  frequency  blocks and
three 10 MHz frequency blocks to broadband PCS. PCS is being deployed throughout
the United  States and may become a  significant  source of  competition  in the
Company's  markets.  PCS  licensees  have been  authorized by the FCC to provide
digital,  wireless  communications  services in markets  served by the  Company.
Similar  technological  advances  or  regulatory  changes in the future may make
available other  alternatives to cellular service,  thereby creating  additional
sources of competition.

         In addition to competition from PCS and the other cellular  licensee in
each  market,   there  is  also  competition  from,  among  other  technologies,
conventional mobile telephone and Specialized Mobile Radio ("SMR") systems, both
of which are able to connect with the landline  telephone  network.  The Company
believes that conventional mobile telephone systems and conventional SMR systems
are  competitively  disadvantaged  because of  technological  limitations on the
capacity of such systems.  The FCC has given  approval,  through  waivers of its
rules,  to Enhanced  Specialized  Mobile Radio  ("ESMR").  ESMR systems may have
cells and frequency  reuse like cellular,  thereby  potentially  eliminating any
current technological limitation.  The first ESMR  systems  were  implemented
in 1993 in Los Angeles.  Although less directly a

                                     - 7 -

substitute for cellular service, wireless data services
and one-way paging service (and, in the future,  two-way paging services) may be
adequate for those who do not need full two-way voice service.

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

Regulation

         The  licensing,  construction,   operation,  acquisition  and  sale  of
cellular  systems are  regulated  by the FCC. In  addition,  certain  aspects of
cellular  system  operations may be subject to public utility  regulation in the
states in which  service is  provided.  Changes in the  regulation  of  cellular
operators or their activities and of other mobile service providers could have a
material adverse effect on the Company's operations.  In addition,  FCC licenses
to provide cellular service are subject to renewal. There may be competition for
licenses upon the  expiration of their  initial  ten-year  terms and there is no
assurance that any license will be renewed.

Value of FCC Licenses

         The Company's  assets consist  principally of intangible  assets in the
form of investments in licenses. In many cases the transfer of such interests is
restricted and subject to prior FCC or state regulatory approval.  In some cases
the transfer of the Company's  interests is subject to rights of first  refusal.
In  addition,   the  future  value  of  all  cellular   interests   will  depend
significantly  upon the  success of the  Company's  business.  While  there is a
current market for cellular licenses,  such a market may not exist in the future
or the  values  obtainable  may be  significantly  lower  than  at  present.  In
addition,  the value of  licenses  may be  affected  by the level of supply  and
demand  for such  licenses  and  therefore  awards of  additional  licenses  for
competitive wireless technologies,  such as those awarded by the auction for PCS
completed by the FCC, may adversely affect the value of cellular licenses.

Markets

         Many of the Company's  markets or market  clusters are located in areas
which are not densely populated and may not benefit from operating  efficiencies
available to systems operated in metropolitan  areas and larger market clusters.
Typically,  smaller  and less  densely  populated  markets  take longer to reach
profitability  and positive cash flow than larger  individual  markets or larger
market clusters.  Due to the fact that the FCC issued cellular licenses for MSAs
in order of market size, most of the Company's MSAs were placed in service later
than larger  MSAs served by other  cellular  operators.  RSAs are several  years
behind the typical  MSA in their  development  and thus may be at least  several
years behind typical MSAs in achieving comparable profitability and cash flow on
a relative basis.

Liquidity and Capital Resources

         The construction of a cellular  telephone  system is  capital-intensive
and requires substantial investment prior to operation. The initial operation of
a  cellular  system  also  requires  additional  investment  to cover

                                     - 8 -

start-up, operating  and  marketing  expenses. 
The Company  intends to continue to pursue
opportunities to acquire cellular interests,  including  additional interests in
cellular  systems in which it owns or has rights to  acquire  an  interest.  The
Company may require  additional  funds to build and operate systems with respect
to any such acquired interests and to pursue the acquisition of new interests.

         Although the Company has begun to generate  positive  operating  income
and cash flows from  operating  activities,  it has required and may continue to
require outside  financing to provide the funds  necessary for  investment.  The
timing and  amount of the  Company's  funding  requirements  will  depend on the
number of licensees acquired by the Company,  the plans for the construction and
operation of  individual  cellular  systems,  and other  relevant  factors.  The
Company may require external  financing to fund acquisitions and to fund capital
requirements  for markets which the Company  currently  owns or has the right to
acquire pursuant to definitive agreements. These requirements may be met through
additional  borrowings  from TDS,  the  issuance  of equity or debt  securities,
vendor financing, bank financing, the sale of assets, or a combination thereof.

         There can be no assurance  that  sufficient  funds will be available to
the  Company on terms or at prices  acceptable  to the  Company.  If  sufficient
funding is not  available to the Company on terms and prices  acceptable  to the
Company,  the Company  would have to reduce its  construction,  development  and
acquisition programs. In the long term, reduction of the Company's construction,
development and acquisition programs would have a negative impact on the ability
of the Company to increase its consolidated revenues and cash flows.

Radiofrequency Emission Concerns

         Media  reports have  suggested  that  certain  radio  frequency  ("RF")
emissions  from  portable  cellular  telephones  might be linked to cancer.  The
Company is not aware of any authoritative evidence linking the usage of portable
cellular  telephones with cancer. The FCC currently has a rulemaking  proceeding
pending to update the guidelines and methods it uses for evaluating RF emissions
in radio  equipment,  including  cellular  telephones.  While the proposal would
impose more restrictive standards on RF emissions from low-power devices such as
portable  cellular  telephones,  it is anticipated that all cellular  telephones
currently marketed and in use will comply with those standards.

Control by Principal Shareholder; Anti-takeover Provisions

         As of the date of this  Prospectus,  TDS owned over 80% of the combined
total of both classes of common  stock of the  Company,  including a majority of
the  outstanding  Common  Shares,  and  controlled  approximately  95% of  their
combined voting power. As a result, TDS was effectively able to elect all of the
Company's seven directors and otherwise control the management and operations of
the Company. See "Description of Capital Stock."

         The  control  of the  Company  by TDS  and  various  provisions  of the
Company's Restated  Certificate of Incorporation,  as amended, may tend to deter
non-negotiated  tender offers or other efforts to obtain  control of the Company
and  thereby  deprive  shareholders  of  opportunities  to sell shares at prices
higher than those prevailing in the market. See "Description of Capital Stock."

Relationship with TDS; Conflicts of Interest

         Directors  and  officers  of TDS and  its  subsidiaries  who  are  also
directors  and officers of the  Company,  and TDS as the  Company's  controlling
shareholder, are in positions involving the possibility of conflicts of interest
with respect to certain transactions  concerning the Company. When the interests
of TDS and the

                                     - 9 -

<PAGE>

Company  diverge,  TDS may exercise its influence in its own best
interests.    See   "Description   of   Capital   Stock-Corporate    Opportunity
Arrangements."

         The  Company  and  TDS  have  entered  into  contractual   arrangements
governing certain transactions and relationships  between them. These agreements
were  executed  prior to the initial  public  offering of the  Company's  Common
Shares and were not the result of arm's-length negotiations.  Accordingly, there
is no  assurance  that the  terms  and  conditions  of these  agreements  are as
favorable  to the  Company as it could have  obtained  from  unaffiliated  third
parties. See "Certain  Relationships and Related  Transactions" in the Company's
most  recent  Annual  Report  on Form  10-K,  which is  incorporated  herein  by
reference.

         In the future,  the Company expects to resolve any potential  conflicts
of interest with TDS on a case by case basis, taking into consideration relevant
factors  including its existing  agreements  with TDS, the  requirements  of the
American Stock Exchange and prevailing corporate practices.


                                 USE OF PROCEEDS

         The Company will not receive any of the cash  proceeds  from any resale
of LYONs by the Standby  Share  Deliverer  or from any sale by Merrill  Lynch of
Common Shares acquired from TDS under the Securities Loan Agreement.

                              DESCRIPTION OF LYONS

         The LYONs were issued under an indenture  dated as of June 1, 1995 (the
"Indenture"),  between the Company and Harris Trust and Savings Bank, as trustee
(the  "Trustee").  A copy of the form of Indenture is filed as an exhibit to the
Registration  Statement  of  which  this  Prospectus  is a part.  The  following
summaries of certain provisions of the LYONs and the Indenture do not purport to
be complete and are subject to, and are qualified in their entirety by reference
to, all the provisions of the LYONs and the Indenture, including the definitions
therein of certain  terms which are not  otherwise  defined in this  Prospectus.
Wherever particular provisions or defined terms of the Indenture (or of the Form
of LYON which is a part  thereof) are referred  to, such  provisions  or defined
terms are incorporated herein by reference. References herein are to sections in
the Indenture and  paragraphs in the Form of LYON. As used in this  "Description
of LYONs," the "Company"  refers to United States Cellular  Corporation and does
not include its subsidiaries, other affiliates, partners or entities in which it
holds an investment.

General

         The  LYONs  are  unsecured   obligations  of  the  Company  limited  to
$745,000,000  aggregate principal amount at maturity and will mature on June 15,
2015.  The  principal  amount at  maturity  of each  LYON is $1,000  and will be
payable at the office of the Paying Agent, initially the Trustee.  (Section 2.03
and Form of LYON, paragraph 3.)

         The LYONs were offered at a substantial  discount from their  principal
amount at maturity. See "Certain Tax Aspects-Original Issue Discount." The LYONs
have no  periodic  payments  of  interest.  The  calculation  of the  accrual of
Original  Issue  Discount  (the  difference  between  the  Issue  Price  and the
principal  amount  at  maturity  of a LYON) in the  period  during  which a LYON
remains  outstanding is on a semi-annual  bond equivalent  basis using a 360-day
year composed of twelve 30-day  months;  such accrual  commenced  from the Issue
Date of the LYONs. (Form of LYON, paragraph 1.) Maturity, conversion (other than
pursuant to a Common Share Delivery Arrangement (as defined below)), purchase by
the  Company  at the  option of a Holder,  or  redemption  of a LYON will  cause
Original Issue  Discount and interest,  if any, to cease to accrue on such LYON,
under the terms and subject to the conditions of the Indenture.  (Section 2.08.)
The Company may not reissue a LYON that has matured or been converted, purchased
by the  Company  at the  option of a Holder,  redeemed  or  otherwise  cancelled
(except for registration of transfer, exchange or replacement thereof), provided
that a LYON  converted  pursuant to a Common Share  Delivery  Arrangement  shall
remain outstanding as described in "Conversion Rights" below. (Section 2.10.)

         The LYONs were issued in fully  registered form,  without  coupons,  in
denominations of $1,000 of principal amount at maturity or an integral  multiple
thereof.  (Form of LYON, paragraph 11.) LYONs may be presented for conversion at
the office of the Conversion  Agent and for exchange or registration of transfer
at the office of the  Registrar,  each such agent  initially  being the Trustee.
(Section   2.03.)  The  Company  will  not  charge  a  service  charge  for  any
registration of transfer or exchange of LYONs;  however, the Company may require
payment by a Holder of a sum  sufficient  to cover any tax,  assessment or other
governmental charge payable in connection therewith. (Section 2.06.)

         The Company will maintain in the Borough of Manhattan,  the City of New
York, an office or agency of the Trustee, Registrar, Paying Agent and Conversion
Agent where LYONs may be presented or surrendered  for payment,  where LYONs may
be surrendered for registration of transfer, exchange,  purchase,  redemption or
conversion and where notices and demands to or upon the Company in respect
of the LYONs and the Indenture may be served, which is currently the corporate 
trust office of the Trustee in such Borough. (Section 4.05.)

Subordination of LYONs; Effect of Corporate Structure

         Indebtedness  evidenced  by the LYONs is  subordinated  in the right of
payment,  as set forth in the  Indenture,  to the prior  payment  in full of all
existing and future Senior Indebtedness of the Company.  (Section 10.01 and Form
of LYON,  paragraph 8.) Senior  Indebtedness  is defined in the Indenture as the
principal of (and premium,  if any) and interest on (including interest accruing
after  the  filing of a  petition  initiating  any  proceeding  pursuant  to any
Bankruptcy Law (including,  with respect to the Vendor Financing  Agreement (and
any other Debt if the  instrument  creating  or  evidencing  the same  expressly
provides  therefor),  such  interest  whether or not  allowed as a claim in such
proceeding,  but, with respect to all other Debt,  only to the extent allowed or
permitted  to the  holder  of such  Debt  against  the  bankruptcy  or any other
insolvency  estate of the Company in such  proceeding)) and other amounts due on
or in connection  with any Debt incurred,  assumed or guaranteed by the Company,
whether outstanding on the date of the Indenture or thereafter incurred, assumed
or  guaranteed,  and all deferrals,  renewals,  extensions and refundings of, or
amendments,  modifications  or supplements to, any such Debt.  Excluded from the
definition  of  Senior  Indebtedness  are  the  following:  (a) any  Debt  which
expressly provides (i) that such Debt shall not be senior in right of payment to
the LYONs, or (ii) that such Debt shall be subordinated to any other Debt of the
Company,  unless such Debt expressly  provides that such Debt shall be senior in
right of payment to the LYONs; and (b) any Debt of the Company in respect of the
LYONs. (Section 10.01.)

         By  reason  of  such  subordination,   in  the  event  of  dissolution,
insolvency,  bankruptcy or other similar  proceedings,  upon any distribution of
assets,  (i) the  Holders of LYONs will be  required  to pay over their share of
such  distribution  to the  trustee  in  bankruptcy,  receiver  or other  person
distributing  the assets of the  Company for  application  to the payment of all
Senior Indebtedness remaining unpaid, to the extent necessary to pay all holders
of Senior Indebtedness in full (Section 10.02.); and (ii) unsecured creditors of
the Company who are not Holders of LYONs or holders of Senior  Indebtedness  may
recover less, ratably, than holders of Senior Indebtedness and may recover more,
ratably, than the Holders of LYONs.

         In the event that the LYONs are declared due and payable prior to their
Stated  Maturity by reason of the  occurrence  of an Event of Default,  then the
Company is obligated to notify promptly  holders of Senior  Indebtedness of such
acceleration. The Company may not pay the LYONs until 120 days have passed after
such  notice  is given  and may  thereafter  pay the  LYONs if the  terms of the
Indenture otherwise permit payment at that time. (Section 10.03.)

         No  payment  of the  principal  amount at  maturity,  Issue  Price plus
accrued Original Issue Discount,  Redemption  Price,  Change in Control Purchase
Price or interest,  if any,  with respect to any LYONs may be made,  nor may the
Company pay cash in respect of the  Purchase  Price (or any portion  thereof) or
upon  conversion  of any LYON (other  than for  fractional  interests  in Common
Shares) or otherwise acquire any LYONs except as set forth in the Indenture,  if
any default with respect to Senior  Indebtedness  occurs and is continuing  that
permits the  acceleration of the maturity thereof and either such default is the
subject of judicial  proceedings or the Company  receives notice of the default,
unless (a) in the case of defaults  on Senior  Indebtedness  other than  payment
defaults, 120 days pass after notice of the default is given and such default is
not then the subject of judicial  proceedings or (b) the default with respect to
the Senior  Indebtedness  is cured or waived and, in each case, the terms of the
Indenture otherwise permit the payment or acquisition of the LYONs at that time.
(Section 10.04.)

         The LYONs are obligations exclusively of the Company. Since the current
operations of the Company are primarily conducted through subsidiaries, the cash
flow and the  consequent  ability to service debt,  including the LYONs,  of the
Company are primarily  dependent upon the earnings of its  subsidiaries  and the
distribution  of those  earnings to, or upon loans or other payments of funds by
those  subsidiaries to, the

                                     - 12 -

<PAGE>


Company.  The subsidiaries are separate and distinct
legal  entities and have no  obligation,  contingent  or  otherwise,  to pay any
amounts  due  pursuant  to the  LYONs or to make any funds  available  therefor,
whether by  dividends,  loans or other  payments.  In  addition,  the payment of
dividends  and  the  making  of  loans  and  advances  to  the  Company  by  its
subsidiaries  may be subject  to  statutory  or  contractual  restrictions,  are
contingent  upon the earnings of those  subsidiaries  and are subject to various
business considerations.

         Any right of the Company to receive  assets of any of its  subsidiaries
upon  their  liquidation  or  reorganization  (and the  consequent  right of the
Holders  of the  LYONs to  participate  in  those  assets)  will be  effectively
subordinated  to the  claims of that  subsidiary's  creditors  (including  trade
creditors),  except to the extent  that the  Company is itself  recognized  as a
creditor of such subsidiary, in which case the claims of the Company would still
be subordinate to any security interest in the assets of such subsidiary and any
indebtedness of such subsidiary senior to that held by the Company.

         There  are  no  restrictions  in  the  Indenture  on  the  creation  of
additional Senior  Indebtedness (or any other  indebtedness).  See the Company's
most recent Annual Report on Form 10-K or Quarterly  Report on Form 10-Q for the
amount of the Company's Senior Indebtedness.

         Under a Vendor Financing  Agreement (the "Vendor Financing  Agreement")
between the Company and NTFC Capital  Corporation  ("NTFC"),  which  constitutes
Senior Indebtedness of the Company, the Company has agreed not to create, incur,
assume or suffer to exist any indebtedness (including capital lease obligations)
that would  cause the sum of such  indebtedness  plus  certain  operating  lease
obligations to exceed an amount equal to $40 per  population  equivalent for all
of  the  then  existing  cellular  markets  owned  by  the  Company,   excluding
indebtedness under the Vendor Financing Agreement and subordinated  indebtedness
(as defined in such  agreement).  The Vendor Financing  Agreement  provides that
indebtedness  evidenced by a LYON will be treated as  subordinated  indebtedness
for  purposes  of such  agreement  only to the  extent  such  LYON  has not been
accelerated,  and that no cash payment is made,  or required to be made,  by the
Company thereunder  (whether at maturity,  upon a change in control,  upon early
redemption or otherwise).

Conversion Rights

         A Holder  of a LYON may  convert  it at any time  before  the  close of
business  on June 15,  2015;  provided,  however,  that if a LYON is called  for
redemption,  the Holder may  convert it only until the close of  business on the
Redemption  Date. On conversion of a LYON, the Company may elect to deliver (or,
with respect to Common Shares, arrange for a Standby Share Deliverer (as defined
below) to deliver)  Common  Shares or an amount of cash  determined as described
below. A LYON in respect of which a Holder has delivered a Purchase  Notice or a
Change in  Control  Purchase  Notice  exercising  the  option of such  Holder to
require the Company to purchase  such LYON may be converted  only if such notice
is  withdrawn  in  accordance  with the terms of the  Indenture.  (Form of LYON,
paragraph 9.) A Holder may convert a portion of such  Holder's  LYONs so long as
such  portion is $1,000  principal  amount at maturity  or an integral  multiple
thereof. (Section 11.01.)

         The initial Conversion Rate is 9.475 Common Shares per LYON, subject to
adjustment upon the occurrence of certain events described below. (Form of LYON,
paragraph 9.) A Holder otherwise entitled to a fractional Common Share shall
receive cash equal to the then current market value of such fractional share.
(Section 11.03.)

         On  conversion  of a LYON, a Holder must (i) complete and manually sign
the  conversion  notice on the back of the LYON (or complete and manually sign a
facsimile  thereof)  and  deliver  such  notice to the  Conversion  Agent,  (ii)
surrender  the  LYON  to  the  Conversion  Agent,  (iii)  if  required,  furnish
appropriate

                                     - 13 -

<PAGE>


endorsements and transfer documents,  and (iv) if required, pay all
transfer or similar taxes.  Pursuant to the Indenture,  the date on which all of
the foregoing requirements have been satisfied is the Conversion Date. (Sections
11.02 and 11.04 and Form of LYON, paragraph 9.)

         On  conversion  of a LYON,  a Holder will not receive any cash  payment
representing  accrued  Original  Issue  Discount.  The  Company's  delivery,  in
connection with  conversions  not involving a Common Share Delivery  Arrangement
(as defined below),  to the Holder of the fixed number of Common Shares (or cash
in the applicable  amount as provided  below) into which the LYON is convertible
(together with the cash payment,  if any, in lieu of a fractional  Common Share)
will be deemed to satisfy the Company's  obligation to pay the principal  amount
of such LYON including the accrued  Original Issue Discount  attributable to the
period  from the Issue Date  through  the  Conversion  Date.  Thus,  the accrued
Original  Issue  Discount  of such LYON is deemed to be paid in full rather than
cancelled,  extinguished or forfeited.  The Conversion Rate will not be adjusted
at any  time  during  the term of the  LYONs  for such  accrued  Original  Issue
Discount.

         In lieu of the delivery of Common  Shares upon notice of  conversion of
any LYON, the Company may elect to pay the Holder  surrendering a LYON an amount
in cash equal to the Sale Price of a Common Share on the Trading Day immediately
prior to the Conversion Date multiplied by the Conversion Rate in effect on such
Trading Day, as adjusted for certain events described below;  provided,  that if
such  payment  of  cash  is not  permitted  pursuant  to the  provisions  of the
Indenture or otherwise, the Company will deliver (or, pursuant to a Common Share
Delivery  Arrangement,  arrange for the delivery of) Common  Shares (and cash in
lieu of fractional  Common  Shares) as set forth below.  Upon  conversion of any
LYON, the Company shall inform the Holder through the Conversion Agent, no later
than two business days following the Conversion Date, (i) of its election of the
delivery of Common  Shares or to pay cash in lieu of delivery of such shares and
(ii) whether or not any such delivery of Common Shares may be a taxable event to
such Holder as a result of such  delivery  being made by means of a Common Share
Delivery Arrangement.  If the Company elects the delivery of Common Shares, such
shares (and cash in lieu of fractional  Common Shares) will be delivered through
the Conversion  Agent as soon as practicable  following the Conversion  Date. If
the Company  elects to pay cash,  such cash  payment  will be made to the Holder
surrendering  such LYON no later  than the fifth  business  day  following  such
Conversion  Date.  (Sections  11.01  and  11.02.)  For a  discussion  of the tax
treatment  of a  Holder  receiving  cash or  Common  Shares,  see  "Certain  Tax
Aspects-Dispositions."

         The  Company may not pay cash upon  conversion  of any LYON (other than
cash in lieu of  fractional  Common  Shares)  (i) if there has  occurred  and is
continuing an Event of Default  described  under "Events of Default;  Notice and
Waiver"  below  (other  than a default  in such  payment  on such LYON) and (ii)
unless the Common  Shares are listed or admitted  to trading on a United  States
national or regional  securities exchange or reported on The Nasdaq Stock Market
("NASDAQ"). (Section 11.1.)

         The "Sale  Price" on any Trading  Day means the closing  sale price per
share for the Common Shares (or, if no closing price is reported, the average of
the bid and ask prices or, if more than one in either  case,  the average of the
average  bid  and the  average  ask  prices)  on such  date as  reported  in the
composite  transactions for the principal United States  securities  exchange on
which the Common Shares
are traded or, if the Common Shares are not listed on a United  States  national
or regional  securities  exchange,  as reported by NASDAQ. A "Trading Day" means
each day on which the securities  exchange or quotation  system which is used to
determine the Sale Price is open for trading or quotation.

         In connection  with the  conversion of any LYON,  the Company may enter
into an arrangement (a "Common Share Delivery  Arrangement")  with a third party
(the "Standby Share  Deliverer"),  initially  Merrill Lynch,  whereby,  upon the
agreement  of the Standby  Share  Deliverer  to so act in  connection  with such
conversion, it will deliver the Common Shares (and any cash payment in lieu of a
fractional Common Share)

                                 - 14 -

<PAGE>


deliverable to the Holder upon such conversion, through
the Conversion  Agent,  in the same amounts and within the same time periods set
forth above for  conversions in respect of which the Company were to deliver the
Common  Shares.  As a result of such a Common Share  Delivery  Arrangement,  the
converted  LYON will not be retired or cancelled,  but shall remain  outstanding
with the Standby Share Deliverer becoming the Holder thereof.  It is anticipated
that the Standby  Share  Deliverer  will resell  LYONs it obtains  pursuant to a
Common Share  Delivery  Arrangement,  although there can be no assurance in this
regard,  and that this  Prospectus  will be  available to be used by the Standby
Share Deliverer to meet any prospectus  delivery  requirements it then has under
the Securities  Act in connection  with (i) the delivery of Common Shares to the
converting Holder pursuant to any Common Share Delivery Arrangement and (ii) any
such resales of LYONs.  The Standby  Share  Deliverer may (with the agreement of
TDS),  but is not obligated to, obtain Common Shares to be so delivered by it in
connection  with such a Common Share Delivery  Arrangement  from TDS pursuant to
the Securities Loan Agreement  described in  "Arrangements  with Merrill Lynch."
For a discussion of the tax treatment of a Holder  receiving  Common Shares from
the Standby  Share  Deliverer,  rather than the Company,  upon  conversion,  see
"Certain Tax Aspects-Dispositions."

         The Conversion Rate will be adjusted for dividends or  distributions on
Common Shares  payable in Common Shares or other  Capital  Stock;  subdivisions,
combinations or certain reclassifications of Common Shares; distributions to all
Holders of Common  Shares;  distributions  to all  Holders  of Common  Shares of
certain rights to purchase Common Shares for a period expiring within 60 days at
less than the Quoted  Price at the time;  and  distributions  to such holders of
assets  or  debt  securities  of the  Company  or  certain  rights  to  purchase
securities of the Company  (excluding cash dividends or other cash distributions
from current or retained earnings other than any  Extraordinary  Cash Dividend).
However,  no  adjustment  need be made (i) if  Holders  may  participate  in the
transaction,  (ii) for rights to purchase  Common  Shares  pursuant to a Company
dividend or interest  reinvestment  plan,  (iii) for changes in the par value of
the  Common  Shares or (iv)  unless  such  adjustment,  together  with any other
adjustments  similarly  deferred,  equals  at  least  1%  of  the  then  current
Conversion  Rate. In cases where the fair market value (per Common Share) of the
assets,  debt  securities  or certain  rights,  warrants  or options to purchase
securities  of the Company  distributed  to  stockholders  equals or exceeds the
Average Quoted Price of the Common Shares,  or such Average Quoted Price exceeds
the fair market value (per Common  Share) of such  assets,  debt  securities  or
rights, warrants or options so distributed by less than $1.00, rather than being
entitled to an  adjustment  in the  Conversion  Rate,  the Holder of a LYON upon
conversion thereof will be entitled to receive, in addition to the Common Shares
(or  cash  in  lieu  thereof,  as set  forth  above)  into  which  such  LYON is
convertible,  the kind and amount of assets, debt securities or rights, warrants
or options  comprising the distribution  that such Holder would have received if
such Holder had  converted  such LYON  immediately  prior to the record date for
determining the stockholders entitled to receive the distribution. The Indenture
permits  the Company to increase  the  Conversion  Rate from time to time at its
discretion.  (Sections 11.06,  11.07,  11.08,  11.10, 11.12, 11.14 and 11.17 and
Form of LYON, paragraph 9.)

         If the  Company is party to a  consolidation,  merger or binding  share
exchange or a transfer of all or substantially  all of its assets,  the right to
convert a LYON into Common Shares may be changed into
a right to  convert  it into the kind and  amount of  securities,  cash or other
assets of the Company or another  person which the Holder would have received if
the  Holder  had  converted  such  Holder's  LYONs   immediately  prior  to  the
transaction. (Section 11.14.)

         In the event of a taxable distribution to holders of Common Shares that
results in an adjustment of the  Conversion  Rate or in the event the Conversion
Rate is increased  at the  discretion  of the Company,  the Holders of the LYONs
may, in certain circumstances, be deemed to have received a distribution subject
to Federal  income tax as a  dividend.  See  "Certain  Tax  Aspects-Constructive
Dividend."

Redemption of LYONs at the Option of the Company

         No sinking fund is provided for the LYONs.  Prior to June 15, 2000, the
LYONs are not  redeemable  at the option of the  Company.  Beginning on June 15,
2000, the Company may redeem the LYONs for cash at any time as a whole,  or from
time to time in part.  (Sections  3.01 and 3.03 and Form of LYON,  paragraph 5.)
Not less  than 30 days' nor more than 60 days'  notice  of  redemption  shall be
given by mail to Holders of LYONs. (Section 3.03 and Form of LYON, paragraph 7.)

         The table below shows Redemption  Prices of a LYON on June 15, 2000, at
each June 15  thereafter  prior to maturity  and at  maturity on June 15,  2015,
which prices reflect the accrued Original Issue Discount calculated through each
such date.  The  Redemption  Price of a LYON  redeemed  between such dates would
include an additional amount  reflecting the additional  Original Issue Discount
accrued from the next preceding date in the table through the actual  Redemption
Date. (Form of LYON, paragraph 5.)

         If less  than all of the  outstanding  LYONs  are to be  redeemed,  the
Trustee  shall select the LYONs to be redeemed in principal  amounts at maturity
of $1,000 or integral  multiples  thereof by lot, pro rata or by another  method
the Trustee considers fair and appropriate.  If a portion of a Holder's LYONs is
selected for partial redemption and such Holder converts a portion of such LYONs
after such selection and prior
to such redemption, such converted portion shall be deemed to be of the portion 
selected for redemption. (Section 3.02.)

Purchase of LYONs at the Option of the Holder

         On June 15,  2000  (the  "Purchase  Date"),  the  Company  will  become
obligated,  and the Company may also elect to become  obligated on June 15, 2005
(the "Optional Purchase Date") to purchase, at the option of the Holder thereof,
any outstanding  LYON for which a written  Purchase Notice has been delivered by
the Holder to the Paying  Agent at any time from the  opening of business on the
date that is 20 Business Days prior to such  Purchase Date or Optional  Purchase
Date,  as  applicable,  until the close of  business  on such  Purchase

                                - 16 -

Date or Optional  Purchase  Date,  and for
which  such  Purchase  Notice  has not  been
withdrawn,  subject to certain additional conditions. The Purchase Price payable
in  respect of a LYON shall be equal to the Issue  Price plus  accrued  Original
Issue  Discount  through  the  Purchase  Date  or  Optional  Purchase  Date,  as
applicable. The Company, at its option, may elect to pay the Purchase Price with
respect to the Purchase Date or the Optional  Purchase Date, as  applicable,  in
cash, Common Shares or TDS Common Equity Securities, or any combination thereof.
TDS has not waived any rights  that it may have under an  agreement  between TDS
and the  Company to  purchase  Common  Shares if the  Company  elects to pay the
Purchase Price (or a portion  thereof) in Common Shares (as of the Purchase Date
or Optional  Purchase Date, as applicable).  As a result, in such event, TDS may
notify  the  Company  that it  intends to  exercise  any such  rights to acquire
additional Common Shares up to an amount equal to TDS's percentage  ownership of
Common Shares at that time (assuming that all outstanding securities that are or
may become convertible into Common Shares,  including LYONs, were converted into
Common  Shares),  at a price per share payable in cash equal to the Market Price
per Common  Share.  See  "Description  of Capital  Stock-Preemptive  and Similar
Rights."  (Section 3.08 and Form of LYON,  paragraph 6.) For a discussion of the
tax  treatment of a Holder  receiving  cash,  Common  Shares,  TDS Common Equity
Securities or any combination thereof, see "Certain Tax Aspects-Dispositions."

         The Company will be required to give notice (the "Company Notice") on a
date not less than 20 Business  Days prior to the Purchase  Date or the Optional
Purchase Date, as  applicable,  to all Holders at their  addresses  shown in the
register of the Registrar  (and to  beneficial  owners as required by applicable
law) stating,  among other things, (i) whether the Company will pay the Purchase
Price  of  LYONs  in  cash,  Common  Shares  or  TDS  Common  Equity  Securities
(identifying  such TDS Common  Equity  Securities)  or any  combination  thereof
(specifying  the  percentages  of each);  (ii) if the  Company  elects to pay in
Common Shares or TDS Common Equity  Securities,  in whole or in part, the method
of  calculating  the Market  Price of such  Common  Shares or TDS Common  Equity
Securities;  and (iii) the  procedures  that  Holders must follow to require the
Company to purchase  LYONs from such Holders.  In addition,  the Company  Notice
with  respect to the Purchase  Date shall  notify  Holders of whether or not the
Company is electing to become  obligated to purchase LYONs, at the option of the
Holders thereof, on the Optional Purchase Date. (Section 3.08.)

         The  Purchase  Notice  given by each  Holder  electing  to require  the
Company to purchase LYONs shall state (i) the  certificate  numbers of the LYONs
to be delivered by such Holder for purchase by the Company;  (ii) the portion of
the principal amount at maturity of LYONs to be purchased, which portion must be
$1,000  or an  integral  multiple  thereof;  (iii)  that  such  LYONs  are to be
purchased by the Company pursuant to the applicable provisions of the LYONs; and
(iv) in the event the Company elects, pursuant to the Company Notice, to pay the
Purchase  Price with respect to the Purchase Date or Optional  Purchase Date, as
applicable, in Common Shares or specified TDS Common Equity Securities, in whole
or in part, but such Purchase Price (or portion(s)  thereof) is ultimately to be
paid to such Holder entirely in cash because any of the conditions to payment of
the Purchase Price (or such portion(s) thereof) in Common
Shares or such specified TDS Common Equity  Securities is not satisfied prior to
the close of  business  on such  Purchase  Date or Optional  Purchase  Date,  as
described below, whether such Holder elects (a) to withdraw such Purchase Notice
as to some or all of the LYONs to which it relates (stating the principal amount
at maturity  and  certificate  numbers of the LYONs as to which such  withdrawal
shall  relate),  or (b) to receive cash in respect of the entire  Purchase Price
(or such  portion(s)  thereof) for all LYONs  subject to such  Purchase  Notice.
Unless the Holder indicates,  in the Purchase Notice or in any written notice of
withdrawal,  such  Holder's  choice with  respect to the  election  described in
clause (iv) above as it relates to the  applicable  portion(s)  of such Purchase
Price, such Holder shall be deemed to have elected to receive cash in respect of
the entire Purchase Price (or such applicable  portion(s) thereof) for all LYONs
subject to such Purchase  Notice in such  circumstances.  (Section  3.08.) For a
discussion  of the tax  treatment of a Holder  receiving  cash instead of Common
Shares or TDS Common Equity Securities, see "Certain Tax Aspects-Dispositions."

                                    - 17 -

<PAGE>

         Any Purchase  Notice may be withdrawn by the Holder by a written notice
of  withdrawal  delivered  to the Paying Agent prior to the close of business on
the  Purchase  Date or Optional  Purchase  Date,  as  applicable.  The notice of
withdrawal  shall state the  principal  amount at maturity  and the  certificate
numbers of the LYONs as to which the withdrawal notice relates and the principal
amount at  maturity,  if any,  which  remains  subject to the  Purchase  Notice.
(Section 3.10.)

         The table below shows the  Purchase  Price of a LYON as of the Purchase
Date and the Optional Purchase Date, if applicable:


          Purchase Date               Purchase Price
          -------------               --------------
          June 15, 2000                  $411.99

     Optional Purchase Date           Purchase Price
     ----------------------           --------------
          June 15, 2005                  $553.68

         If the Company elects to pay the Purchase  Price,  in whole or in part,
in Common Shares or TDS Common Equity Securities, the number of Common Shares or
shares of the specified TDS Common Equity  Securities to be delivered in respect
of the  portion  of the  Purchase  Price  to be paid in  Common  Shares  or such
specified  TDS Common  Equity  Securities  shall be equal to such portion of the
Purchase  Price divided by the Market Price (as defined below) of a Common Share
or a share of such specified TDS Common Equity  Securities,  as  applicable.  No
fractional  Common Shares or fractional  shares of TDS Common Equity  Securities
will be delivered upon any purchase by the Company of LYONs through the delivery
of Common  Shares or TDS Common  Equity  Securities  in payment,  in whole or in
part,  of the Purchase  Price.  Instead,  the Company will pay cash based on the
Market Price for all fractional  Common Shares or TDS Common Equity  Securities.
(Section 3.08.) See "Certain Tax Aspects-Dispositions."

         The "Market  Price"  means the average of the Sale Prices of the Common
Shares or the specified TDS Common Equity  Securities,  as  applicable,  for the
five  trading  day  period  ending  on (if the third  Business  Day prior to the
Purchase Date or Optional Purchase Date, as applicable,  is a trading day or, if
not, then on the last trading day prior to) the third  Business Day prior to the
Purchase Date or Optional Purchase Date, as applicable,  appropriately  adjusted
to take into account the occurrence,  during the period  commencing on the first
of such  trading  days  during  such five  trading day period and ending on such
Purchase Date or Optional Purchase Date, of (i) certain events that would result
in an  adjustment  of the  Conversion  Rate with respect to the Common Shares or
(ii) certain  similar  events with respect to the  specified  TDS Common  Equity
Securities,  as  applicable.  The  "Sale  Price"  of the  Common  Shares  or the
specified TDS Common Equity  Securities,  as  applicable,  on any date means the
closing per share sale price
(or if no closing sale price is reported,  the average of the bid and ask prices
or, if more than one in either  case,  the  average of the  average  bid and the
average ask prices) on such date as reported in composite  transactions  for the
principal  United States  securities  exchange on which the Common Shares or the
specified TDS Common Equity  Securities,  as  applicable,  are traded or, if the
Common Shares or the specified TDS Common Equity Securities, as applicable,  are
not listed on a United  States  national or  regional  securities  exchange,  as
reported  by  NASDAQ.  Because  the  Market  Price of the  Common  Shares or the
specified TDS Common Equity  Securities,  as applicable,  is determined prior to
the Purchase Date or Optional  Purchase  Date, as  applicable,  Holders of LYONs
bear the  market  risk with  respect  to the value of the  Common  Shares or the
specified TDS Common Equity Securities,  as applicable,  to be received from the
date such Market Price is determined  to the Purchase Date or Optional  Purchase
Date,  as  applicable.  The Company may pay the  Purchase  Price (or any portion
thereof) in Common Shares or the specified TDS Common Equity  Securities only if
the information  necessary to calculate the applicable Market Price is published
in a daily  newspaper of national  circulation  and only if the Common Shares or
the  specified  TDS  Common  Equity  Securities,  as  applicable,  are listed or
admitted to trading on a United States national or regional  securities exchange
or reported by NASDAQ. (Section 3.08).

                                - 18 -

<PAGE>


         Upon  determination  of the  actual  number of Common  Shares or of the
specified  TDS  Common  Equity  Securities  in  accordance  with  the  foregoing
provisions,  the Company will publish such determination in a daily newspaper of
national circulation. (Section 3.08.)

         The Company's right to purchase LYONs, in whole or in part, with Common
Shares or with TDS Common Equity  Securities is subject to the  satisfaction  of
various conditions,  including; (i) the registration of the Common Shares or the
specified TDS Common Equity Securities, as applicable,  under the Securities Act
and the  Exchange  Act, if required;  and (ii) any  necessary  qualification  or
registration  under  applicable  state  securities law or the availability of an
exemption from such  qualification and registration.  If such conditions are not
satisfied  with respect to a Holder or Holders prior to the close of business on
the Purchase Date or Optional Purchase Date, as applicable, the Company will pay
the  Purchase  Price of the LYONs of such  Holder or Holders  entirely  in cash.
(Section  3.08.) See  "Certain  Tax  Aspects-Dispositions."  The Company may not
change the form of  consideration  (or  components or  percentages of components
thereof) to be paid once the Company has given its Company  Notice to Holders of
LYONs  except as described in the second  sentence of this  paragraph.  (Section
3.08).

         The Company will comply with the  provisions of Rule 13e-4,  Rule 14e-1
and any  other  tender  offer  rules  under the  Exchange  Act which may then be
applicable  and  will  file  Schedule  13E-4  or  any  other  schedule  required
thereunder in connection  with any offer by the Company to purchase LYONs at the
option of Holders. (Section 3.13.)

         Payment of the  Purchase  Price for a LYON for which a Purchase  Notice
has been  delivered and not validly  withdrawn is  conditioned  upon delivery of
such LYON (together with necessary endorsements) to the Paying Agent at any time
(whether  prior to, on or after the Purchase Date or Optional  Purchase Date, as
applicable)  after delivery of such Purchase Notice.  (Section 3.08.) Payment of
the Purchase  Price for such LYON will be made  promptly  following the later of
(i) the Purchase Date or Optional  Purchase  Date, as  applicable,  and (ii) the
time of delivery of such LYON.  (Section  3.08.) If the Paying Agent  holds,  in
accordance  with the terms of the Indenture,  money or securities  sufficient to
pay the Purchase  Price of such LYON on the Business Day  following the Purchase
Date or Optional  Purchase Date, as  applicable,  then,  immediately  after such
Purchase Date or Optional  Purchase Date, such LYON will cease to be outstanding
and Original  Issue  Discount on such LYON will cease to accrue,  whether or not
such LYON is delivered to the Paying  Agent,  and all other rights of the Holder
shall  terminate  (other  than the right to  receive  the  Purchase  Price  upon
delivery of the LYON). (Section 2.08.)

         The Company's ability to purchase LYONs with cash may be limited by the
terms of its then-existing  borrowing  agreements.  No LYONs may be purchased at
the option of Holders for cash if there has occurred (prior to, on, or after the
giving,  by the Holders of such LYONs, of the required  Purchase  Notice) and is
continuing an Event of Default with respect to the LYONs described under "Events
of Default; Notice and Waiver" below (other than a default in the payment of the
Purchase Price with respect to such LYONs). (Section 3.10.)

Change in Control Permits Purchase of LYONs at the Option of the Holder

         In the event of any Change in Control (as defined below) of the Company
occurring  on or prior to June 15,  2000,  each  Holder  of LYONs  will have the
right,  at the  Holder's  option,  subject  to the terms and  conditions  of the
Indenture,  to require the Company to purchase all or any portion (provided that
the principal amount at maturity must be $1,000 or an integral multiple thereof)
of the  Holder's  LYONs  as of the  date  that is 35  Business  Days  after  the
occurrence of such Change in Control (a "Change in Control  Purchase Date")

                               - 19 -

<PAGE>


at a cash price equal to the Issue Price plus accrued Original Issue Discount
through the Change in Control  Purchase Date (the "Change in Control  Purchase
Price"). (Section 3.09 and Form of LYON, paragraph 6.)

         Within 15 Business  Days after the  occurrence  of a Change in Control,
the Company is  obligated  to mail to the Trustee and to all Holders of LYONs at
their addresses shown in the register of the Registrar (and to beneficial owners
as required by applicable law) a notice  regarding the Change in Control,  which
notice shall include a form of Change in Control  Purchase  Notice (a "Change in
Control Purchase  Notice") to be completed by the Holder and shall state,  among
other  things:  (i) the events  causing a Change in Control and the date of such
Change  in  Control,  (ii) the last  date on which  the  purchase  right  may be
exercised,  (iii) the  Change in  Control  Purchase  Price,  (iv) the  Change in
Control  Purchase  Date,  (v) the name and  address of the Paying  Agent and the
Conversion  Agent, (vi) the Conversion Rate and any adjustments  thereto,  (vii)
that LYONs with respect to which a Change in Control Purchase Notice is given by
the Holder may be converted  only if the Change in Control  Purchase  Notice has
been  withdrawn in accordance  with the terms of the  Indenture,  and (viii) the
procedures  that Holders must follow to exercise these rights.  The Company will
cause a copy of such notice to be  published  in a daily  newspaper  of national
circulation. (Section 3.09.)

         To exercise  this right,  the Holder must deliver the Change in Control
Purchase  Notice to the Paying Agent  (initially the Trustee) prior to the close
of  business  on the  Change in  Control  Purchase  Date.  The Change in Control
Purchase  Notice  shall  state (i) the  certificate  numbers  of the LYONs to be
delivered by the Holder thereof for purchase by the Company; (ii) the portion of
the principal amount at maturity of LYONs to be purchased, which portion must be
$1,000 or any  integral  multiple  thereof;  and (iii) that such LYONs are to be
purchased by the Company pursuant to the applicable provisions of the LYONs.
(Section 3.09.)

         Any Change in Control Purchase Notice may be withdrawn by the Holder by
a written notice of withdrawal  delivered to the Paying Agent prior to the close
of business on the Change in Control  Purchase  Date.  The notice of  withdrawal
shall state the principal amount at maturity and the certificate  numbers of the
LYONs as to which the  withdrawal  notice  relates and the  principal  amount at
maturity,  if any, which remains subject to a Change in Control Purchase Notice.
(Section 3.10.)

         Payment of the Change in Control  Purchase Price for a LYON for which a
Change in Control  Purchase Notice has been delivered and not validly  withdrawn
is conditioned upon delivery of such LYON (together with necessary endorsements)
to the Paying Agent at any time (whether prior to, on or after the
Change in Control  Purchase  Date) after the  delivery of such Change in Control
Purchase Notice. (Section 3.09.) Payment of the Change in Control Purchase Price
for such LYON will be made promptly following the later of the Change in Control
Purchase  Date or the time of  delivery  of such  LYON.  (Section  3.10.) If the
Paying  Agent  holds,  in  accordance  with the  terms of the  Indenture,  money
sufficient  to pay the  Change  in  Control  Purchase  Price of such LYON on the
Business Day following the Change in Control  Purchase Date,  then,  immediately
after such Change in Control Purchase Date, Original Issue Discount on such LYON
will cease to accrue, whether or not such LYON is delivered to the Paying Agent,
and all other  rights of the Holder  shall  terminate  (other  than the right to
receive  the  Change in  Control  Purchase  Price  upon  delivery  of the LYON).
(Section 2.08).

         Under the Indenture,  a "Change in Control" of the Company is deemed to
have  occurred  at such time as (i) any person,  including  its  Affiliates  and
Associates  (other than TDS, the Company,  their  Subsidiaries,  their  employee
stock ownership plans or any of their other employee  benefit plans, the Carlson
Family  (meaning  LeRoy T.  Carlson,  his family  members  (meaning  his spouse,
siblings  and  lineal  descendants),  estate  and  heirs  and any trust or other
investment  vehicle  for the  primary  benefit  of any of such  persons or their
respective family members or heirs (collectively,  the "Carlson Family"))) files
a Schedule  13D or 14D-1 (or any  successor  schedule,  form or report under the
Exchange Act) disclosing that such person has become the

                                   - 20 -

beneficial owner of 50%
or more of the combined  voting power of all of the Company's  then  outstanding
equity  securities (of all classes or series) or such other Capital Stock of the
Company into which such equity  securities  are  reclassified  or changed,  with
certain exceptions,  (ii) the number of outstanding Common Shares (or such other
class or series of Capital Stock of the Company into which the Common Shares are
reclassified  or changed) the  beneficial  owners of which are not Affiliates of
the  Company  is at any time  reduced  to less  than 10  million  Common  Shares
(appropriately adjusted to reflect the impact of any stock dividend, subdivision
or  combination)  as a result of  acquisitions  of Common  Shares (or such other
Capital  Stock)  by,  or in  concert  with,  the  Company,  TDS,  any  of  their
Subsidiaries,  Affiliates,  employee stock ownership  plans or employee  benefit
plans, or the Carlson Family, (iii) there shall be consummated any consolidation
or merger of the  Company  (a) in which the  Company  is not the  continuing  or
surviving  corporation  or (b)  pursuant  to which the  Common  Shares  would be
converted  into cash,  securities or other  property,  in each case other than a
consolidation or merger of the Company in which the holders of the Common Shares
and Series A Common  Shares  immediately  prior to the  consolidation  or merger
have,  directly or indirectly,  50% or more of the combined  voting power of the
common equity securities of the continuing or surviving corporation  immediately
after such  consolidation or merger;  or (iv) TDS and its Subsidiaries  cease to
collectively be beneficial owners of at least 50% of (x) the total of the Common
Shares  and Series A Common  Shares (or such other  classes or series of Capital
Stock of the Company into which such Common Shares or Series A Common Shares are
reclassified  or changed) then  outstanding or (y) the combined  voting power of
all of the  Company's  then  outstanding  equity  securities  (of all classes or
series) or such  other  Capital  Stock of the  Company  into  which such  equity
securities are reclassified or changed (the event or transaction  giving rise to
such circumstances described in (x) or (y) of item (iv) being referred to as the
"Designated  Transaction")  and, in either  case (x) or (y) of item (iv),  there
shall occur a Rating Decline (as defined below) within the time period described
below in the  definition of Rating Decline and with a Reference Date (as defined
below) occurring on or prior to June 15, 2000. The Indenture does not permit the
Board of Directors of the Company to waive the Company's  obligation to purchase
LYONs at the  option  of  Holders  in the event of a Change  in  Control  of the
Company. (Section 3.09.)

         Under the Indenture a "Rating  Decline" will be deemed to have occurred
if, on any date within the period (the  "Rating  Period")  beginning on the date
(the  "Reference  Date")  of the  earlier  to  occur  of (a)  the  first  public
announcement  by TDS,  the Company or any other person of an intention to effect
the Designated Transaction and (b) the occurrence of such Designated Transaction
and ending on the date that
is 60 days  after the later to occur of (A) the  occurrence  of such  Designated
Transaction  and (B) the first  public  announcement  by TDS, the Company or any
other person of the  occurrence of such  Designated  Transaction,  either of the
following events has occurred: (i) the LYONs shall be rated by any Rating Agency
at any time during the Rating  Period at a rating which is lower than the rating
of the LYONs by such Rating Agency on the Rating Date by more than one gradation
(including  gradations  within  Rating  Categories  as  well as  between  Rating
Categories)  or (ii) any Rating  Agency shall have  withdrawn  its rating of the
LYONs during the Rating Period.

         "Rating  Agency"  is  defined  in the  Indenture  as  Standard & Poor's
Corporation and its successors ("S&P"), and Moody's Investors Service,  Inc. and
its successors  ("Moody's"),  or, if S&P or Moody's,  or both,  shall not make a
rating of the LYONs publicly  available,  a nationally  recognized United States
statistical rating agency or agencies,  substituted by the Company, with written
notice to the Trustee, for S&P or Moody's, or both, as the case may be.

         "Rating  Category"  is defined in the  Indenture  as each major  rating
category  symbolized  by (x) in the case of S&P, AAA, AA, A, BBB, BB, B, CCC, CC
and  C  and  each  such  Rating   Category   shall  include  pluses  or  minuses
("gradations")  modifying such capital letters; (y) in the case of Moody's, Aaa,
Aa, A, Baa,  Ba, B, Caa, Ca and C and each such Rating  Category  shall  include
added numerals such as 1, 2 or 3 ("gradations")

                               - 21 -

<PAGE>


modifying such letters; and (z) with respect to any other  Rating  Agency, 
comparable or  equivalent  symbols.  "Rating  Date" is  defined  as the date
that is 60 days  prior to the  Reference Date.

         The Company will comply with the  provisions of Rule 13e-4,  Rule 14e-1
and any  other  tender  offer  rules  under the  Exchange  Act which may then be
applicable  and  will  file  Schedule  13E-4  or  any  other  schedule  required
thereunder in connection  with any offer by the Company to purchase LYONs at the
option of  Holders  upon a Change in  Control.  (Section  3.13.)  The  Change in
Control  purchase  feature of the LYONs may in certain  circumstances  make more
difficult  or  discourage  a  takeover  of the  Company.  The  Change in Control
purchase feature,  however, was not the result of management's  knowledge of any
specific  effort to  accumulate  Common  Shares or Series A Common  Shares or to
obtain control of the Company by means of a merger,  tender offer,  solicitation
or otherwise, or part of a plan by management to adopt a series of anti-takeover
provisions.  See  "Description of Capital Stock."  Instead,  a change in control
purchase  feature was a standard term  contained in other LYONs  offerings  that
have been  marketed  by Merrill  Lynch,  as  underwriter,  and the terms of such
feature resulted from negotiations between the Company and Merrill Lynch, as the
underwriter of the LYONs.

         The Company  could,  in the future,  enter into  certain  transactions,
including certain  recapitalizations of the Company, that would not constitute a
Change in Control with respect to the Change in Control  purchase feature of the
LYONS, but that would increase the amount of Senior Indebtedness  outstanding at
such time.  No LYONs may be  purchased at the option of Holders upon a Change in
Control of the Company if there has occurred  (prior to, on or after the giving,
by the Holders of such LYONs, of the required Change in Control Purchase Notice)
and is continuing an Event of Default with respect to the LYONs  described under
"Events  of  Default;  Notice and  Waiver"  below  (other  than a default in the
payment of the Change in Control  Purchase  Price with  respect to such  LYONs).
(Sections  3.10 and 10.03.)  Further,  the LYONs are  subordinated  to the prior
payment of Senior  Indebtedness  as  described  under  "Subordination  of LYONs;
Effect of Corporate Structure" above.

         The  Vendor   Financing   Agreement  does  not  include  any  provision
accelerating  the debt incurred  thereunder  upon a change in control,  but does
include   covenants   prohibiting   the  Company  from   entering  into  certain
transactions,  including a merger, consolidation or sale of substantially all of
the Company's assets,  unless the Company is the surviving entity or obtains the
consent of NTFC.

Mergers and Sales of Assets by the Company

         The Company may not consolidate  with or merge into any other person or
convey,  transfer or lease all or substantially all of its properties and assets
to another person,  unless,  among other items, (i) the resulting,  surviving or
transferee  person (if other than the Company) is organized  and existing  under
the laws of the United States, any state thereof or the District of Columbia and
such person  assumes  all  obligations  of the  Company  under the LYONs and the
Indenture,  and (ii) the Company or such successor  person shall not immediately
thereafter  be in  default  under  the  Indenture.  Upon the  assumption  of the
Company's obligations by such a person in such circumstances, subject to certain
exceptions, the Company shall be discharged from all obligations under the LYONs
and the Indenture.  (Section  5.01.)  Although such  transactions  are permitted
under the Indenture, certain of the foregoing transactions occurring on or prior
to June 15, 2000 could constitute a Change in Control of the Company  permitting
each  Holder to require  the  Company to  purchase  the LYONs of such  Holder as
described above. (Section 3.09.)

Events of Default; Notice and Waiver

         The Indenture  provides that, if an Event of Default  specified therein
shall have happened and be continuing,  either the Trustee or the Holders of not
less than 25% in  aggregate  principal  amount  at  maturity  of the LYONs  then
outstanding  may declare the Issue  Price of the LYONs plus the  Original  Issue
Discount  on the  LYONs  accrued  through  the  date of such  declaration  to be
immediately  due and payable.  In the case of certain  events of  bankruptcy  or
insolvency,  the  Issue  Price of the LYONs  plus the  Original  Issue  Discount
accrued thereon through the occurrence of such event shall automatically  become
and be immediately due and payable. Upon acceleration, as described in either of
the preceding sentences,  the subordination provisions of the Indenture preclude
any  payment  being  made to  Holders  of LYONs for at least 120 days.  (Section
10.03.) See  "Subordination  of LYONs;  Effect of  Corporate  Structure."  Under
certain  circumstances,  the Holders of a majority in aggregate principal amount
at maturity of the  outstanding  LYONs may  rescind any such  acceleration  with
respect to the LYONs and its  consequences.  (Section  6.02.) Interest shall, to
the extent  permitted by law,  accrue and be payable on demand upon a default in
the  payment of the  principal  amount at  maturity,  Issue  Price plus  accrued
Original  Issue  Discount,  cash in respect of a conversion,  or any  Redemption
Price,  Purchase  Price or Change in Control  Purchase Price with respect to any
LYON and such interest  shall be compounded  semi-annually.  The accrual of such
interest on overdue  amounts  shall be in lieu of, and not in  addition  to, the
continued accrual of Original Issue Discount. (Form of LYON, paragraph 1.)

         Under the  Indenture,  Events of Default are defined as: (i) default in
payment of the principal  amount at maturity,  Issue Price plus accrued Original
Issue Discount,  Redemption Price,  Purchase Price or Change in Control Purchase
Price with  respect to any LYON when such  becomes due and payable or default in
payment of cash upon conversion of any LYON (in each case whether or not payment
is prohibited by the provisions of the  Indenture);  (ii) failure by the Company
to deliver Common Shares (or cash in lieu of fractional Common Shares) when such
Common Shares (or cash in lieu of fractional  Common  Shares) are required to be
delivered following conversion of a LYON and the continuance of such default for
10 days; (iii) failure by the Company to comply with any of its other agreements
in the LYONs or the  Indenture  upon  receipt  by the  Company of notice of such
default by the Trustee or by Holders of not less than 25% in aggregate principal
amount at maturity of the LYONs then  outstanding  and the Company's  failure to
cure (or obtain a waiver of) such  default  within 60 days after  receipt by the
Company of such notice;  (iv) default under any bond,  debenture,  note or other
evidence of  indebtedness  for money borrowed by the Company having an aggregate
outstanding  principal  amount of in excess of $25,000,000,  which default shall
have resulted in such indebtedness being accelerated,  without such indebtedness
being discharged or such  acceleration  having been rescinded or annulled within
twenty days after receipt of notice
thereof by the Company  from the Trustee or the Company and the Trustee from the
Holders of not less than 25% in  aggregate  principal  amount at maturity of the
LYONs then  outstanding  (unless such default has been cured or waived);  or (v)
certain events of bankruptcy or insolvency. (Section 6.01.)

         The Trustee shall give notice to Holders of the LYONs of any continuing
default  known to the  Trustee  within  90 days  after the  occurrence  thereof;
provided,  that the Trustee may withhold  such notice,  as to any default  other
than a payment  default,  if it  determines in good faith that  withholding  the
notice is in the interests of the Holders. (Section 7.05.)

         The Holders of a majority in aggregate  principal amount at maturity of
the  outstanding  LYONs may direct the time,  method and place of conducting any
proceeding  for any remedy  available to the Trustee or exercising  any trust or
power  conferred on the Trustee,  provided that such  direction  shall not be in
conflict with any law or the Indenture and subject to certain other limitations.
(Section  6.05.)  Before  proceeding  to  exercise  any right or power under the
Indenture at the  direction of such  Holders,  the Trustee  shall be entitled to
receive from such Holders  reasonable  security or indemnity  satisfactory to it
against the costs,  expenses  and

                             - 23 -

<PAGE>


liabilities  which might be incurred by it in
complying with any such  direction.  (Section  7.01.) No Holder of any LYON will
have any right to pursue any remedy with respect to the  Indenture or the LYONs,
unless (i) such Holder shall have previously given the Trustee written notice of
a  continuing  Event of Default;  (ii) the Holders of at least 25% in  aggregate
principal amount at maturity of the outstanding  LYONs shall have made a written
request to the Trustee to pursue such remedy;  (iii) such Holder or Holders have
offered to the Trustee  reasonable  security or  indemnity  satisfactory  to the
Trustee;  (iv) the  Holders  of a  majority  in  aggregate  principal  amount at
maturity  of the  outstanding  LYONs  have not  given the  Trustee  a  direction
inconsistent with such request within 60 days after receipt of such request; and
(v) the Trustee shall have failed to comply with the request  within such 60-day
period.  (Section 6.06.)

         However,  the  right  of any  Holder  (x)  to  receive  payment  of the
principal amount at maturity,  Issue Price plus accrued Original Issue Discount,
cash in respect of a conversion,  Redemption Price,  Purchase Price or Change in
Control Purchase Price with respect to any LYON and any interest in respect of a
default  in the  payment of any such  amounts on such LYON,  on or after the due
date  expressed in such LYON,  (y) to convert LYONs or (z) to institute suit for
the  enforcement  of any such  payments or  conversion  shall not be impaired or
adversely affected without such Holder's consent. (Section 6.07.) The Holders of
at least a majority in aggregate principal amount at maturity of the outstanding
LYONs may waive an  existing  default and its  consequences,  other than (i) any
default in any  payment on the  LYONs,  (ii) any  default  which  constitutes  a
failure to convert any LYON in accordance with its terms or (iii) any default in
respect of certain  covenants or provisions  in the  Indenture  which may not be
modified  without  the  consent  of the  Holder  of each  LYON as  described  in
"Modification" below. (Section 6.04.)

         The Company is required to furnish to the Trustee  annually a statement
as to any  default  by the  Company in the  performance  and  observance  of its
obligations under the Indenture. (Section 4.03.)

Modification

         Without the consent of any Holder of LYONs, the Company and the Trustee
may  amend  the   Indenture  to  cure  any   ambiguity,   omission,   defect  or
inconsistency,  to  provide  for the  assumption  by a  successor  person of the
obligations  of the Company under the Indenture,  to provide for  uncertificated
LYONs in addition to certificated LYONs (so long as any uncertificated LYONs are
in registered form for purposes of the Internal  Revenue Code), to eliminate the
Company's option to pay cash in lieu of delivering Common Shares upon conversion
of LYONs (other than cash in lieu of fractional Common Shares and
except  with  respect  to such  elections  already  made)  or to  eliminate  the
Company's option to enter into Common Share Delivery  Arrangements in respect of
conversions of LYONs (except for those already entered into), to make any change
that does not  adversely  affect  the rights of any Holder of LYONs or to comply
with any requirement of the Commission in connection with the  qualification  of
the  Indenture  under  the  Trust  Indenture  Act of 1939.  (Section  9.01.)  No
amendment may be made to the  subordination  provisions  of the  Indenture  that
adversely  affects  the  rights  of  any  holder  of  Senior  Indebtedness  then
outstanding,  unless  the  holders  of such  Senior  Indebtedness  (as  required
pursuant  to the terms of such  Senior  Indebtedness)  consent  to such  change.
(Section 9.02.)

         Modification  and  amendment  of  the  Indenture  or the  LYONs  may be
effected by the  Company and the Trustee  with the consent of the Holders of not
less than a majority in aggregate principal amount at maturity of the LYONs then
outstanding.  However,  without the consent of each Holder affected thereby,  no
amendment may, among other things:  (i) reduce the principal amount at maturity,
Issue Price, amount of cash to be paid by the Company in respect of a conversion
of LYONs,  Purchase Price,  Change in Control Purchase Price or Redemption Price
with respect to any LYON, or extend the stated maturity of any LYON or alter the
manner or rate of accrual of Original  Issue  Discount or interest,  or make any
LYON  payable in money or 

                              - 24 -

<PAGE>


securities  other than that stated in the LYON;  (ii)
make any  reduction in the  principal  amount at maturity of LYONs whose Holders
must consent to an  amendment  or any waiver  under the  Indenture or modify the
Indenture  provisions  relating to such  amendments  or waivers;  (iii) make any
change  that  adversely  affects  the right to convert  any LYON or the right to
require the Company to purchase a LYON  (including  the right to receive cash in
lieu of Common Shares upon conversion or cash or TDS Common Equity Securities in
lieu of, or in combination  with,  Common Shares upon purchase by the Company at
the option of Holders of LYONs,  other than  elimination of the Company's option
to pay cash in lieu of  delivering  Common  Shares upon  conversion  of LYONs as
described  above);  (iv) modify the provisions of the Indenture  relating to the
subordination  of the LYONs in a manner adverse to the Holders of the LYONs;  or
(v) impair the right to institute  suit for the  enforcement of any payment with
respect to, or conversion of, the LYONs. (Section 9.02.)

Limitations of Claims in Bankruptcy

         If a bankruptcy  proceeding is commenced in respect of the Company, the
claim of the  Holder of a LYON is,  under  Title 11 of the United  States  Code,
limited to the Issue Price of the LYON plus that portion of the  Original  Issue
Discount  that has  accrued  from the date of issue to the  commencement  of the
proceeding.  In addition, the Holders of the LYONs will be subordinated in right
of  payment  to  Senior   Indebtedness  and  effectively   subordinated  to  the
indebtedness  and  other   obligations  of  the  Company's   subsidiaries.   See
"Subordination of LYONs; Effect of Corporate Structure."

Taxation of LYONs

         See "Certain Tax Aspects"  for a discussion  of certain  United  States
Federal income tax aspects that will apply to Holders of LYONs.

Information Concerning the Trustee

         Harris  Trust and Savings Bank is  currently  the  Trustee,  Registrar,
Paying  Agent  and  Conversion  Agent  under  the  Indenture  and  custodian  in
connection with the Securities Loan Agreement.  Harris Trust and Savings Bank is
also the transfer agent and registrar for the Company's Common Shares.



                          DESCRIPTION OF CAPITAL STOCK

         The  authorized  capital stock of the Company  consists of  140,000,000
Common Shares,  $1.00 par value;  50,000,000  Series A Common Shares,  $1.00 par
value;  and 5,000,000 shares of Preferred  Stock,  $1.00 par value,  issuable in
series.  See the  Company's  most recent Annual Report on Form 10-K or Quarterly
Report on Form 10-Q for the  number of shares of  capital  stock of the  Company
which are outstanding.

Preferred Stock

         Pursuant to the Company's  Restated  Certificate of  Incorporation,  as
amended,  the Board of Directors is authorized to establish and designate one or
more series of Preferred Stock,  without further  authorization of the Company's
shareholders,  and  to fix  the  number  of  shares  and  the  relative  rights,
preferences and limitations of any such series,  except that so long as not less
than 500,000 shares of Series A Common Shares are outstanding,  no shares of any
series of Preferred Stock may have more than one vote per share,  have the right
to vote as a separate  class with  respect to elections of directors or (subject
to any  requirements  of  applicable  law) any other  matter,  or be issued  for
consideration of less than $100 per share. The shares of any series of Preferred
Stock need not be identical in any respect with the shares of any other series.

                               - 25 -

<PAGE>


Voting Rights

         Each Series A Common Share is entitled to ten votes on all matters, and
each Common Share is entitled to one vote on all matters. The Company's Restated
Certificate of Incorporation,  as amended, provides that the number of directors
shall be not less than three, and that the directors shall be divided into three
classes serving staggered three-year terms. The holders of Common Shares, voting
as a separate class,  are entitled to elect 25% of the directors  (rounded up to
the  nearest  whole  number),  and the  holders  of Series A Common  Shares  and
Preferred Stock, voting together, are entitled to elect the remaining directors.
However,  if at the time of an election of directors  the  outstanding  Series A
Common  Shares  represent  less than  12.5% of the total  outstanding  shares of
common stock of the Company,  then the holders of Series A Common Shares and the
Preferred  Stock do not have class voting  rights in the election of  directors,
and the holders of Common Shares,  Series A Common Shares,  and Preferred  Stock
vote together for the election of the  remaining  75% of the directors  (rounded
down to the  nearest  whole  number).  See "Risk  Factors-Control  by  Principal
Shareholder; Antitakeover Provisions."

         Except as mentioned  above and except for matters where  applicable law
requires  the  approval  by one or more  classes  of stock  voting  as  separate
classes, all classes of stock of the Company vote as a single class.

Dividend Rights

         Subject  to the  payment  of all  dividends  accumulated  and unpaid on
outstanding shares of Preferred Stock, the holders of Common Shares are entitled
to receive such  dividends as may be declared  from time to time by the Board of
Directors.  Unless  the same or greater  dividends,  on a per share  basis,  are
declared  and  paid at the same  time on  Common  Shares,  no  dividends  may be
declared or paid on the Series A Common Shares.

         In the case of stock dividends, the Board of Directors is authorized to
distribute  shares of a particular class of the Company's  capital stock only as
follows: (i) Common Shares may be paid to the
holders  of Common  Shares  and  proportionately  to  holders of Series A Common
Shares;  (ii) Series A Common Shares may be paid to the holders of Common Shares
and  proportionately  to the holders of Series A Common Shares;  or (iii) Common
Shares may be paid to the  holders of Common  Shares and Series A Common  Shares
may be paid  proportionately to the holders of Series A Common Shares. The Board
of Directors  also is  authorized  to  distribute  to Common and Series A Common
Shareholders  shares of any subsidiary that has two classes of common stock with
each class possessing respective rights,  preferences and limitations similar to
the respective  rights,  preferences  and limitations of the Common and Series A
Common Shares.  Thus, although it has no present intention to do so, the Company
could  recapitalize  any of its subsidiaries and then spin the subsidiary off to
the Company's shareholders, with the holders of Series A Common Shares receiving
the  subsidiary's  Series A Common  Shares  and the  holders  of  Common  Shares
receiving the subsidiary's Common Shares.

         The  Company  has not paid  any cash  dividends  and,  except  for cash
dividends payable on any future series of Preferred Stock, intends to retain all
earnings for use in the Company's  business.  In addition,  the Revolving Credit
Agreement  with TDS prohibits  the payment of dividends on the Company's  Common
Shares  and Series A Common  Shares,  except to the  extent of  one-half  of the
cumulative  consolidated net income, if any, of the Company for the period after
July 1, 1989,  which currently  prevents the Company from paying  dividends.  In
addition,  the Vendor Financing  Agreement  imposes certain  restrictions on the
payment of  dividends if certain  financial  requirements  under such  agreement
would be violated.

                                 - 26 -

<PAGE>


Conversion Rights

         The Common Shares have no conversion rights. The Series A Common Shares
are convertible,  on a share-for-share  basis, into Common Shares.  The Series A
Common Shares which are converted may not be reissued.

Liquidation Rights

         Upon  liquidation,  the  holders  of Common  Shares and Series A Common
Shares are  entitled  to receive a pro rata  share of all  assets  available  to
shareholders  after  payment  of the  aggregate  liquidation  preference  of any
Preferred Stock then outstanding.

Preemptive and Similar Rights

         Under the Company's Restated Certificate of Incorporation,  as amended,
TDS, as the holder of Series A Common Shares,  has preemptive rights to purchase
any additional  Series A Common Shares issued or sold by the Company,  including
treasury shares other than Series A Common Shares not sold for cash.

         In  addition  to the  preemptive  rights  granted to TDS as a holder of
Series A Common Shares of the Company  pursuant to the Restated  Certificate  of
Incorporation,  as amended, of the Company,  TDS has the right under an Exchange
Agreement  between the Company and TDS to  subscribe  to any  issuance of Common
Shares or any other  voting  securities  of the  Company,  or of any  securities
convertible  into or  exchangeable  for, or carrying a right to  subscribe to or
acquire,  Common Shares or any other voting  securities  of the Company.  To the
extent an issuance is made for  consideration  other than cash,  the fair market
value of the non-cash  consideration  will be  determined  by  resolution of the
Board of Directors of the Company. The proportion of each such issuance that TDS
has the right to  subscribe  to (which  right may be  exercisable  in full or in
part) is  equal to the  proportion  of the  Common  Shares  that TDS  would  own
immediately  before the  issuance  if all  securities  of the  Company  that are
convertible into Common Shares
(including  securities  convertible  into another class that is convertible into
Common  Shares  and  including   securities  that  in  the  future  will  become
convertible) were converted (successively, if necessary) into Common Shares. The
rights of TDS to subscribe  to Common  Shares may be  transferred  to any one or
more transferees from TDS of any Common Shares,  Series A Common Shares,  or any
securities  convertible  into or  exchangeable  for,  or  carrying  a  right  to
subscribe to or acquire,  shares of either such class.  In  connection  with the
initial  offering  of the LYONs by the  Company,  TDS waived its right under the
Exchange  Agreement to purchase LYONs (which are convertible into Common Shares)
and any Common Shares  deliverable  upon conversion  thereof.  However,  TDS has
expressly  not waived any rights it might have under the  Exchange  Agreement to
acquire  Common  Shares in the event the Company  determines  to deliver  Common
Shares in  connection  with the  election  of  holders  to cause the  Company to
purchase  LYONs on the Purchase Date or Optional  Purchase Date. TDS has agreed,
in the event it has such rights, that the fair market value of the consideration
paid for the Common  Shares for  purposes of any such  purchase  right,  will be
equal to the Market Price of the Common Shares as  determined  for such Purchase
Date or  Optional  Purchase  Date under the  Indenture.  TDS has also waived any
rights it may have  permitting  it to transfer its rights to  subscribe  for and
purchase such Common Shares on the Purchase Date or Optional  Purchase Date. See
"Description of LYONs-Purchase of LYONs at the Option of the Holder."

         Pursuant to a Common Stock  Purchase  Agreement,  dated April 24, 1987,
between the Company and S.A.  Coditel,  an affiliate of Coditel Brabant S.A. and
Codiservices S.A. (collectively,  "Coditel"), as a result of the transfer of the
rights of S.A.  Coditel to  Coditel,  for a period of 10 years after the closing
date of such  agreement,  Coditel has the right to  subscribe to any issuance of
the Company's  common stock or of securities 

                                 - 27 -

<PAGE>


convertible into such common stock
except  for  issuance  to  employees   and  directors  of  the  Company  or  its
subsidiaries  or any issuance  made in  connection  with the  acquisition  of an
interest  in  any  other  entity.   To  the  extent  an  issuance  is  made  for
consideration   other  than  cash,   the  fair  market  value  of  the  non-cash
consideration  will be determined by resolution of the Board of Directors of the
Company.  The amount of common stock of each of such issue to which  Coditel may
subscribe  shall not exceed such  proportion  of such issue as (i) the amount of
the Company's common stock held by Coditel immediately prior to the time of such
issuance  bears to (ii) the sum of the amount of issued and  outstanding  common
stock  of the  Company  and  the  amount  of such  common  stock  issuable  upon
conversion of all of the Company's issued and outstanding  securities,  warrants
and options  (regardless  of whether such  securities,  warrants and options are
then convertible), immediately prior to the time of such issuance. In connection
with the initial offering of the LYONs by the Company,  Coditel waived its right
to purchase  LYONs  (which are  convertible  into Common  Shares) and any Common
Shares deliverable upon conversion thereof.

Redemption by Company

         The Company may redeem stock  (other than Series A Common  Shares) from
any  holder  at the  lesser of (i) fair  market  value,  or (ii)  such  holder's
purchase  price if purchased  within a year of such  redemption,  to prevent the
loss,  or  permit  the  reinstatement  of any  license  or  franchise  from  any
governmental  agency,  where  such loss is based  upon such  holder  failing  to
possess  qualifications  prescribed by such governmental  agency.  This right of
redemption  could be  applicable  to a person  receiving  Common Shares upon the
conversion  of LYONS by the Holder  thereof or upon  purchase  by the Company of
LYONs at the  option of the Holder  thereof if such  person  falls  within  such
category of holders based on qualifications  prescribed by any such governmental
agency at the time.

Corporate Opportunity Arrangements

         The  Company's  Restated  Certificate  of  Incorporation,  as  amended,
provides  that,  so  long  as at  least  500,000  Series  A  Common  Shares  are
outstanding, the Company may not, without the written consent of
TDS, engage in any non-cellular  activities.  The Company has been informed that
TDS intends to give its consent to the acquisition of any non-cellular  interest
that is incidental to the acquisition of a cellular interest. However, TDS could
impose conditions on any such consent,  including a requirement that the Company
resell any  non-cellular  interest to TDS or that the Company give TDS the right
of first refusal with respect to such sale.

         The Restated Certificate of Incorporation,  as amended,  also restricts
the  circumstances  under  which  the  Company  is  entitled  to  claim  that an
opportunity,  transaction,  agreement or other  arrangement to which TDS, or any
person in which TDS has or  acquires a financial  interest,  is or should be the
property of the  Company or its  subsidiaries.  In general,  so long as at least
500,000 Series A Common Shares are outstanding, the Company will not be entitled
to any such "corporate opportunity" unless it relates solely to the construction
of, the ownership of interests in, and/or the management of, cellular  telephone
systems, and then only if such corporate opportunity did not arise in any way as
a result of the rights  otherwise  retained by TDS. The Restated  Certificate of
Incorporation  allows the  Company  to pursue  future  opportunities  to provide
cellular service and design, consulting, engineering and construction management
services  for cellular  telecommunications  systems  located  outside the United
States.

General

         All issued and outstanding shares of Preferred Stock, Common Shares and
Series A Common Shares are fully paid and  nonassessable,  and all Common Shares
issued by the Company upon  conversion of LYONs

                              - 28 -

<PAGE>


or upon purchase of LYONs by the Company at the option  of the  Holders  thereof
will  be  fully  paid  and nonassessable when issued.

         The transfer  agent and registrar  for the  Company's  Common Shares is
Harris Trust and Savings Bank, Chicago, Illinois. The Company serves as transfer
agent and registrar for shares of Preferred Stock and Series A Common Shares.

         The Company will distribute  annual reports to its  shareholders  which
will contain its audited financial statements.


                               CERTAIN TAX ASPECTS

         The  following  summary of material  United States  Federal  income tax
considerations  is for general  information  only. The summary is based upon the
Internal Revenue Code of 1986, as amended (the "Code"), its legislative history,
existing and proposed regulations  thereunder,  administrative rulings and court
decisions, all as in effect and existing on the date hereof and all of which are
subject to change at any time.  The tax  treatment of a Holder of LYONs may vary
depending upon the Holder's  particular  situation.  Certain Holders  (including
insurance companies,  tax-exempt organizations,  individual retirement and other
tax-deferred   accounts,   financial   institutions,   broker-dealers,   foreign
corporations,  and  individuals  who are not citizens or residents of the United
States) may be subject to special  rules not  discussed  below.  This summary is
limited to investors who hold LYONs as capital assets.  Accordingly,  purchasers
of  LYONs  should  consult  their  own tax  advisors  as to the  particular  tax
consequences to them of acquiring, holding, converting or otherwise disposing of
the LYONs,  including the  applicability  and the effect of any state,  local or
foreign tax laws and any changes in applicable tax laws.

         The Company has been advised by its counsel,  Sidley & Austin,  that in
the opinion of such counsel the LYONs will be treated as indebtedness for United
States   Federal   income  tax  purposes.   The  following   discussion  of  tax
considerations assumes that the LYONs will be so treated.

Original Issue Discount

         The LYONs were issued at a substantial  discount  from their  principal
amount at maturity.  For Federal income tax purposes, the difference between the
issue  price (the first  price at which a  substantial  amount of the LYONs were
sold for money) and the  principal  amount at maturity of each LYON  constitutes
Original  Issue  Discount.  Holders  of the LYONs  will be  required  to include
Original Issue Discount in income periodically over the term of the LYONs before
the receipt of the cash,  Common Shares,  TDS Common Equity  Securities or other
payments attributable to such income.

         A Holder of a LYON must include in gross income for Federal  income tax
purposes the sum of the daily  portions of Original  Issue Discount with respect
to the LYON for each day during the taxable year or portion of a taxable year on
which such Holder holds the LYON (for purposes of this tax discussion,  "Accrued
Original Issue Discount"). The daily portion is determined by allocating to each
day of the accrual  period a pro rata portion of an amount equal to the adjusted
issue price of the LYON at the beginning of the accrual period multiplied by the
yield to maturity of the LYON  (determined  by  compounding at the close of each
accrual period and adjusted for the length of the accrual  period).  The accrual
period will  generally  be each six month  period  which ends on the day in each
calendar  year  corresponding  to the maturity  date of the LYON or the date six
months before such maturity date. The  information  returns  provided to Holders
and the Internal  Revenue Service (the  "Service") by the Company  regarding the
accrual of  Original  Issue  Discount  will be

                            - 29 -

<PAGE>


based on these six month  accrual periods.
Treasury  regulations,  however,  permit a Holder to select an accrual
period of any length and to vary the length of the accrual  period over the term
of the debt instrument,  provided that each accrual period is no longer than one
year and each scheduled payment of principal or interest occurs on the final day
of an accrual  period or on the first day of an  accrual  period.  The  adjusted
issue  price of the LYON at the start of any  accrual  period  will be the issue
price of the LYON  increased  by the Accrued  Original  Issue  Discount for each
prior accrual period.  Under these rules,  Holders will have to include in gross
income  increasingly   greater  amounts  of  Original  Issue  Discount  in  each
successive  accrual period.  The Company will be required to furnish annually to
the Service and to certain noncorporate Holders information regarding the amount
of Original Issue Discount attributable to that year.

         A Holder who purchases a LYON at an  "acquisition  premium" will reduce
the amount of Original  Issue Discount  otherwise  includible in gross income to
reflect the acquisition  premium. A LYON is purchased at an acquisition  premium
if,  immediately  after its  purchase,  its  adjusted  basis is greater than its
adjusted  issue  price  (as  defined  above).  If a  LYON  is  purchased  at  an
acquisition  premium,  the Holder  reduces the amount of Original Issue Discount
otherwise  includible  in income  during an accrual  period by a  fraction.  The
numerator  of this  fraction  is the  excess of the  adjusted  basis of the LYON
immediately after its acquisition by the purchaser over the adjusted issue price
of the LYON.  The  denominator  of the  fraction is the excess of the  principal
amount at  maturity of such LYON over the LYON's  adjusted  issue  price.  As an
alternative  to  reducing  the  amount  of  Original  Issue  Discount  otherwise
includible in income by this fraction,  the Holder may elect to compute Original
Issue  Discount  accruals  by  treating  the  purchase as a purchase at original
issuance and applying the constant-yield method described above.

Dispositions

         General.  A Holder's  basis for  determining  gain or loss on the sale,
redemption, retirement, conversion, purchase by the Company or other disposition
of a LYON (any such event,  a  "Disposition")  will be  increased by any Accrued
Original Issue Discount includable in such Holder's gross income.  Except as set
forth under "Market  Discount" below, gain or loss recognized upon a Disposition
under the rules described below will generally be capital gain or loss, and will
be  long-term  capital  gain or loss if the LYON has been held for more than one
year. A Holder's  obligation  to include in gross  income the daily  portions of
Original Issue Discount with respect to a LYON will  prospectively  terminate on
the date of a Disposition.

         Sale, Redemption,  Retirement or Purchase by the Company for Cash. Upon
the sale,  redemption,  retirement or purchase by the Company of a LYON for cash
(including  pursuant  to a  Purchase  Notice  or a Change  in  Control  Purchase
Notice),  a Holder will  recognize  capital gain or loss equal to the difference
between the amount of cash received and such Holder's  adjusted tax basis in the
LYON.

         Conversion.  The tax treatment of a Holder who elects to convert a LYON
will depend on whether the Company  chooses (i) to deliver cash, (ii) to deliver
Common Shares (other than through a Standby Share Deliverer) or (iii) to arrange
for a Standby  Share  Deliverer  to deliver  Common  Shares.  In no event will a
combination  of cash and Common  Shares be delivered to a Holder with respect to
the  conversion  of any given LYON (except with respect to cash received in lieu
of a fractional Common Share).

         If the Company  delivers cash, a Holder will recognize  capital gain or
loss  equal to the  difference  between  the  amount of cash  received  and such
Holder's adjusted tax basis in the LYON.

         If the Company  delivers  Common  Shares  (other than through a Standby
Share Deliverer),  a Holder will not recognize gain or loss (except with respect
to cash  received in lieu of a fractional  Common  Share),  and the Holder's tax
basis in the Common  Shares  received will be the same as the Holder's tax basis
in the

                               - 30 -

<PAGE>


LYON on the date of conversion (exclusive of any tax basis allocable to a
fractional Common Share). The holding period for the Common Shares received will
include  the  holding  period for the LYON  tendered  to the Company in exchange
therefor,  except that the holding period of Common Shares  allocable to Accrued
Original  Issue  Discount  may  commence  on  the  day  following  the  date  of
conversion.

         If the Company arranges for a Standby Share Deliverer to deliver Common
Shares,  a Holder will  recognize  capital gain or loss equal to the  difference
between the fair market value of such Common  Shares (plus any cash  received in
lieu of a fractional  Common Share) and such Holder's  adjusted tax basis in the
LYON.  The Holder's  tax basis in the Common  Shares  received  will be equal to
their fair market value at the time of  conversion,  and the holding  period for
such Common Shares will begin on the day following the date of conversion.

         As a result of these rules,  a Holder's  receipt of Common  Shares upon
conversion of a LYON will either be taxable or tax-free, depending on the source
of the Common  Shares.  Because  the source of the Common  Shares will depend on
whether  the  Company,  at its option  (with the  agreement  of a Standby  Share
Deliverer  in the case of a  Common  Share  Delivery  Arrangement),  chooses  to
deliver the Common Shares or arranges for a Standby Share  Deliverer to do so, a
Holder  will have no control  over  whether  its  receipt of Common  Shares upon
conversion  is taxable or  tax-free.  The Company  will  notify each  converting
Holder,  through the Conversion  Agent, of the source of the Common Shares on or
prior  to the  delivery  thereof,  at  which  time  the  Holder  will be able to
determine whether its receipt of the Common Shares is taxable or tax-free.

         Purchase at the Option of the  Holder.  The tax  treatment  of a Holder
that elects to have a LYON purchased by the Company with respect to the Purchase
Date or, if  applicable,  the Optional  Purchase Date will depend on the type of
consideration the Company elects to deliver.

         If the Company  elects to pay the  Purchase  Price in cash,  TDS Common
Equity  Securities or any combination  thereof,  a Holder will recognize capital
gain or loss equal to (i) the sum of any cash received and the fair market value
of any TDS Common Equity Securities received,  minus (ii) such Holder's adjusted
tax  basis  in the  LYON.  The  Holder's  tax  basis  in any TDS  Common  Equity
Securities  received  will be equal to their  fair  market  value  upon  receipt
following  the  Purchase  Date (or  Optional  Purchase  Date),  and the Holder's
holding  period  for the TDS  Common  Equity  Securities  will  begin on the day
following such receipt.

         If the Company  elects to pay the Purchase  Price in Common  Shares,  a
Holder will not recognize  gain or loss (except with respect to cash received in
lieu of a  fractional  Common  Share),  and the Holder's tax basis in the Common
Shares received will be the same as the Holder's tax basis in the LYON exchanged
therefor  (exclusive of any tax basis  allocable to a fractional  Common Share).
The  holding  period for the Common  Shares  received  will  include the holding
period for the LYON  tendered to the Company in exchange  therefor,  except that
the holding period of Common Shares allocable to Accrued Original Issue Discount
may commence on the day following such exchange.

         If the Company  elects to pay the Purchase  Price partly in cash and/or
TDS  Common  Equity  Securities  and  partly in  Common  Shares,  a Holder  will
recognize  capital gain (but not loss) equal to the lesser of (i) the sum of any
cash  received  and the fair market  value of any TDS Common  Equity  Securities
received  and (ii)  such sum plus the fair  market  value of the  Common  Shares
received  minus such Holder's  adjusted tax basis in the LYON.  The Holder's tax
basis in any TDS Common Equity  Securities  received will be equal to their fair
market value upon receipt  following  the  Purchase  Date (or Optional  Purchase
Date), and the Holder's holding period for the TDS Common Equity Securities will
begin on the day following  such  receipt.  The Holder's tax basis in the Common
Shares received will be the same as the Holder's tax basis in the LYON

                                 - 31 -

<PAGE>


exchanged
therefor, decreased by the sum of any cash received and the fair market value of
any TDS Common  Equity  Securities  received and increased by the amount of gain
recognized.  The holding period for the Common Shares  received will include the
holding period for the LYON tendered to the Company in exchange therefor, except
that the holding  period of Common Shares  allocable to Accrued  Original  Issue
Discount may commence on the day following such exchange.

         Cash  in  Lieu  of  Fractional  Shares.  Cash  received  in  lieu  of a
fractional  Common  Share upon a  Disposition  of a LYON  should be treated as a
payment  in  exchange  for  the  fractional   interest  in  such  Common  Share.
Accordingly,  the receipt of cash in lieu of a  fractional  Common  Share should
generally  result in capital gain or loss,  if any  (measured by the  difference
between the cash received for the  fractional  Common Share and the Holder's tax
basis in the fractional Common Share).

         Market Discount. If a Holder acquires a LYON and has a tax basis in the
LYON that is less than its adjusted issue price (as defined  above),  the amount
of such  difference  is treated  as "market  discount"  for  federal  income tax
purposes,  unless  such  difference  is  less  than  1/4 of one  percent  of the
principal  amount at  maturity  multiplied  by the number of  complete  years to
maturity (from the date of acquisition).

         Under the market  discount  rules of the Code,  a Holder is required to
treat any gain on the sale, exchange,  retirement or other disposition of a LYON
as ordinary  income to the extent of the accrued  market  discount  that has not
previously been included in income. If such LYON is disposed of by the
Holder in certain  otherwise  nontaxable  transactions  (e.g.,  gifts),  accrued
market  discount will be includible as ordinary  income by the Holder as if such
Holder had sold the LYON at its then fair market value.

         Notwithstanding  the rules set forth in the preceding  paragraph,  if a
Holder  disposes of a LYON having  accrued market  discount in a  nonrecognition
transaction  in  which  the  Holder  receives  property  the  basis  of which is
determined  in whole or in part by  reference  to the  basis  of the  LYON,  the
accrued  market  discount is generally  not  includible in income at the time of
such transaction.  Instead, the accrued market discount attaches to the property
received in the nonrecognition  transaction and is recognized as ordinary income
upon the  disposition  of such property by the Holder.  This rule would apply to
the receipt of Common  Shares  pursuant to the  conversion of a LYON (other than
through a Standby Share  Deliverer) and the receipt of Common Shares pursuant to
a purchase  by the  Company  (to the  extent the  accrued  market  discount  was
allocable thereto).

         In  general,  the  amount  of  market  discount  that  has  accrued  is
determined on a ratable basis,  by allocating an equal amount of market discount
to each day of every accrual period. A Holder may,  however,  elect to determine
the amount of accrued market discount  allocable to any accrual period through a
constant-yield calculation. This election is made on a LYON-by-LYON basis and is
irrevocable.

         A Holder  may not be  allowed  to deduct  immediately  a portion of the
interest  expense on any  indebtedness  incurred or  continued to purchase or to
carry LYONs with market discount.  A Holder may elect to include market discount
in income  currently as it accrues  (either on a ratable basis or, if the Holder
so elects, on a constant-yield basis) in which case the  interest-deferral  rule
set forth in the preceding  sentence will not apply. Such an election to include
market discount in income currently applies to all debt instruments  acquired by
the  Holder on or after the first day of the first  taxable  year to which  such
election  applies  and is  irrevocable  without the  consent of the  Service.  A
Holder's tax basis in a LYON will be increased by the amount of market  discount
included in such Holder's income under such an election.

Constructive Dividend

         If at any  time  the  Company  makes  a  distribution  of  property  to
stockholders that would be taxable to such stockholders as a dividend for United
States Federal income tax purposes (for example,  distributions  of evidences of
indebtedness  or assets of the Company,  but  generally  not stock  dividends or
rights to  subscribe  for  Common  Shares)  and,  pursuant  to the  antidilution
provisions of the LYONs,  the  Conversion  Rate of the LYONs is increased,  such
increase  will  likely  result in taxable  income for the  Holders of the LYONs.
Similarly, if the Conversion Rate is increased at the discretion of the Company,
such increase will likely result in taxable income for the Holders of the LYONs.


                        TELEPHONE AND DATA SYSTEMS, INC.

         TDS  currently  owns  all of the  Series  A  Common  Shares  which  are
outstanding and all of the shares of Preferred Stock which are outstanding.  TDS
also currently owns over 50% of the Common Shares which are outstanding. See the
Company's  most recent  Annual  Report on Form 10-K or Quarterly  Report on Form
10-Q for the number of shares of capital  stock of the Company which are held by
TDS.  This  Prospectus  covers  750,000 of such  Common  Shares  owned by TDS in
connection with the  transactions  contemplated by the Securities Loan Agreement
described  under  "Arrangements  with Merrill  Lynch." Since TDS is only lending
such Common Shares to Merrill Lynch under the Securities Loan Agreement, Merrill
Lynch is obligated to return such borrowed Common Shares to TDS.


                         ARRANGEMENTS WITH MERRILL LYNCH

         Merrill  Lynch,  as Standby  Share  Deliverer and at the request of the
Company, may agree to acquire, through the delivery of Common Shares, LYONs upon
conversion by the Holders  thereof and Merrill Lynch may resell such LYONs.  Any
such sales may be made directly to one or more purchasers at negotiated  prices,
at market  prices  prevailing  at the time of sale or at prices  related to such
market prices. See "Description of LYONs-Conversion Rights." This Prospectus may
be used by the Standby Share Deliverer in connection with such transactions.

         Merrill Lynch may from time to time offer Common  Shares  borrowed from
TDS under the Securities  Loan Agreement  directly to one or more  purchasers at
negotiated  prices, at market prices prevailing at the time of sale or at prices
related to such market  prices.  The Securities  Loan  Agreement  provides that,
subject to certain restrictions and with the agreement of TDS, Merrill Lynch may
from time to time borrow,  return and reborrow Common Shares from TDS; provided,
however,  that the number of Common Shares  borrowed under the  Securities  Loan
Agreement at any time may not exceed  750,000 (which number of Common Shares may
be reduced from time to time by TDS). Merrill Lynch shall be obligated generally
to return  borrowed  securities  on three  business  days'  notice from TDS. The
obligation of Merrill Lynch to return  borrowed  securities  shall be secured by
cash, an irrevocable letter of credit or U.S.  Government  Obligations,  in form
satisfactory  to the custodian under the Securities Loan Agreement, in an amount
not less than 102% of the market value of the borrowed securities. If the market
value of the borrowed  securities falls or rises over time, Merrill Lynch may be
required to provide  additional  collateral  or may be entitled to the return of
collateral.  The  recalculation  of the market value of the borrowed  securities
will be done on a daily  basis.  Any fees  payable  by Merrill  Lynch  under the
Securities  Loan  Agreement  will be paid  directly to 
the custodian.  The  Securities  Loan  Agreement is intended to facilitate
ordinary  trading and  market-making  activity in the LYONs by Merrill Lynch and
may also be used by Merrill Lynch, as Standby Share Deliverer,  to obtain Common
Shares   deliverable  by  it  in  connection  with  any  Common  Share  Delivery
Arrangement

                                - 33 -

entered into with the Company,  as  described  in  "Description  of
LYONs-Conversion Rights." The availability of Common Shares under the Securities
Loan Agreement,  if any, at any time is, as described above, not assured and any
such availability does not assure market-making activity in the LYONs by Merrill
Lynch.  This Prospectus may be used by Merrill Lynch in connection with the sale
of Common Shares  borrowed by Merrill Lynch from TDS under the  Securities  Loan
Agreement.  Merrill Lynch is not under any obligation to engage in market-making
activity  with  respect  to the  LYONs,  or to agree to any  such  Common  Share
Delivery  Arrangement,  and any  market-making,  or activity as a Standby  Share
Deliverer, actually engaged in by Merrill Lynch may cease at any time.

         The Company has agreed to indemnify Merrill Lynch against certain civil
liabilities,  including  liabilities under the Securities Act, and to contribute
to payments Merrill Lynch may be required to make in respect thereof.

         Merrill Lynch has previously  marketed (and  anticipates  continuing to
market)  securities of issuers  under the  trademark  "LYONs." The LYONs offered
hereby contain certain terms and provisions  which are different from such other
previously marketed LYONs, the terms and provisions of which also vary.
See "Description of LYONs."

         From time to time  Merrill  Lynch and  certain of its  affiliates  have
performed,  and may in the  future  perform,  investment  banking  or  financial
advisory services for the Company and TDS.
