SECURITIES LOAN AGREEMENT, dated _________ ___,
               1995, between MERRILL LYNCH, PIERCE, FENNER &
               SMITH INCORPORATED ("Borrower") and TELEPHONE AND
               DATA SYSTEMS, INC. ("Lender").


          WHEREAS, Lender and Harris Trust and Savings Bank ("Harris") are
parties to a Custody Agreement dated              , 1995 (the "Custody
Agreement") pursuant to which Harris is acting as custodian (in such capacity,
the "Custodian");

          WHEREAS, pursuant to the Securities Lending Customer Agreement Custody
Account, dated             , 1995 (the "Customer Agreement"), between Lender,
Custodian and Harris, Harris may lend securities held in the custody account
established pursuant to the Custody Agreement to borrowers pursuant to borrower
loan agreements in the form attached to the Customer Agreement;


          WHEREAS, Borrower and Harris are parties to a Borrowing Agreement,
dated             , 1995 (the "Borrowing Agreement"), pursuant to which the
Borrower may borrow securities from Harris, including, without limitation,
the Common Shares, par value $1.00 per share, of United States Cellular
Corporation, a Delaware corporation ("USM") (including any other shares of
capital stock of USM, into which such Common Shares shall be reclassified or
changed, the "USM Common Shares"), held in the custody account (the "Custody
Account") established under the Custody Agreement.


          NOW THEREFORE, in consideration of the premises and of the mutual
covenants herein contained, Borrower and Lender hereby agree as follows:

          1.   LOANS OF SECURITIES.


          1.1.  Subject to the terms and conditions of the Borrowing
Agreement, Borrower may, from time to time, initiate a transaction whereby
Borrower seeks to borrow USM Common Shares held in the Custody Account from
Harris.  So long as the total number of USM Common Shares so borrowed by
Borrower from Harris under the Borrowing Agreement and not yet returned
thereunder would not, after giving effect to any request (a "Request") by
Borrower that Harris make a Loan, be greater than the amount permitted in
accordance with Schedule A hereto and Borrower is not in default under the
Borrowing Agreement or this Agreement, such Request shall be a valid request
for a Loan under the Borrowing Agreement.  A Loan







under the Borrowing Agreement shall not occur until the Loaned Securities are
delivered by Harris to Borrower in accordance with the Borrowing Agreement.
It shall be a condition to the obligations of Lender to make USM Common
Shares available for borrowing by Borrower from Harris under the Borrowing
Agreement, that Borrower shall have delivered the Collateral to Harris as
required by the Borrowing Agreement.



          The terms "Business Day", "Collateral", "Loan", and "Loaned
Securities", and certain other terms are defined below.



          1.2.  Notwithstanding anything to the contrary herein or in the
Borrowing Agreement, the Custody Agreement or the Customer Agreement, Lender
and Borrower agree that Lender will not make USM Common Shares available
through the Custody Account to be loaned by Harris to Borrower and Borrower
will not borrow USM Common Shares held in the Custody Account from Harris
pursuant to the Borrowing Agreement or otherwise, if Lender shall have orally
notified Custodian and Borrower that no USM Common Shares held in the Custody
Account and that do not constitute Loaned Securities may then be loaned by
Harris or borrowed by Borrower from Harris pursuant to the Borrowing
Agreement.  Any such notice shall be confirmed in writing (including by
facsimile transmission) to Custodian and to Borrower by the end of the
Business Day following the date of

                                      2




such notice.  Lender may provide any such notice at its sole discretion, at
any time or times and for any reason.  Lender shall not inform Custodian or
Borrower in any such notice or otherwise (x) of the reason why USM Common
Shares may not then be loaned by Harris or borrowed by Borrower from
Harris pursuant to the Borrowing Agreement or (y) of the subsection of
Section 1 of this Agreement pursuant to which such notice is being given.
Any such notice shall (i) apply to all or any specified portion (provided
that such portion shall result in a whole number of USM Common Shares then
being able to be loaned by Harris and borrowed by Borrower from Harris
under the Borrowing Agreement) of the USM Common Shares that do not
constitute Loaned Securities at the time of receipt of such notice by
Custodian and Borrower and (ii) be in effect until the receipt by Custodian
and Borrower of the notice provided for in Section 1.4 hereof.



          1.3.  Notwithstanding anything to the contrary herein or in the
Borrowing Agreement, the Custody Agreement or the Customer Agreement, if (i)
USM shall have notified Lender of the occurrence of any of the events
specified in Section 2(k)(i) of the Registration Rights Agreement, dated as
of ____________ __, 1995, by and between Borrower, USM and Lender (the
"Registration Rights Agreement") or (ii) Lender is otherwise aware of the
occurrence of any such event (which in the case of the event described in
Section 2(k)(i)(c) of the Registration Rights Agreement, shall mean, for
purposes of this Section 1.3(ii), that USM or Lender, on the advice of its
respective counsel, reasonably concludes that it is inadvisable as a matter
of federal securities law that the Prospectus (as defined in the Registration
Rights Agreement) continue to be used), Lender shall in any such case (unless
a notice from Lender pursuant to Section 1.2 (relating to all of the USM
Common Shares that do not constitute Loaned Securities) or this Section 1.3
is already then in effect) promptly orally notify Custodian and Borrower that
no USM Common Shares that do not constitute Loaned Securities are then
available through the Custody Account to be loaned by Harris or borrowed by
Borrower from Harris pursuant to the Borrowing Agreement or otherwise.
Lender shall confirm any such notice in writing (including by facsimile
transmission) to Custodian and to Borrower by the end of the Business Day
following the date of such notice. Lender shall not inform Custodian or
Borrower in any such notice or otherwise (x) of the reason why USM Common
Shares held in the Custody Account may not then be loaned by Harris or
borrowed by Borrower from Harris pursuant to the Borrowing Agreement or (y)
of the subsection of Section 1 of this Agreement pursuant to which such
notice is being given.  Any such notice shall (i) apply to all (but not less
than all) of the USM Common Shares that do not constitute Loaned Securities
and (ii) be in effect until the receipt by Custodian

                                      3




and Borrower of the notice provided for in Section 1.4 hereof.



          1.4.  If (i) Lender shall have notified Custodian and Borrower in
accordance with Section 1.2 or 1.3 that all or any specified portion of USM
Common Shares are not then available through the Custody Account to be loaned
by Harris or borrowed by Borrower from Harris pursuant to the Borrowing
Agreement or otherwise and (ii) none of the events requiring a notice
provided for in Section 1.3 hereof is then continuing, Harris may resume the
lending of USM Common Shares held in the Custody Account and Borrower may
resume the borrowing of such USM Common Shares from Harris pursuant to the
Borrowing Agreement at any time after Lender orally notifies Custodian and
Borrower of the resumption of the availability of USM Common Shares through
the Custody Account for lending by Harris to Borrower and Lender shall
confirm any such notice in writing (including by facsimile transmission) to
Custodian and to Borrower by the end of the Business Day following the date
of such notice.

          1.5.  Notwithstanding anything to the contrary herein or in the
Borrowing Agreement, the Custody Agreement or the Customer Agreement, any
notice provided for in Section 1.2 or 1.3 hereof shall advise Harris not to
deliver any USM Common Shares from the Custody Account as Loaned Securities
to Borrower under the Borrowing Agreement pursuant to any Request until the
receipt by Harris of a Request subsequent to Custodian receiving a notice
provided for in Section 1.4 hereof.

          1.6.  Notwithstanding anything to the contrary herein or in the
Borrowing Agreement, the Custody Agreement or the Customer Agreement, if
Borrower shall make a Request at a time when any USM Common Shares subject to
such Request are not then available through the Custody Account to be loaned
by Harris or borrowed by Borrower from Harris under the Borrowing Agreement
or otherwise because Lender has given the notice specified in Section 1.2 or
1.3 hereof that all or a specified portion of USM Common Shares are not then
available through the Custody Account to be loaned by Harris or borrowed by
Borrower from Harris under the Borrowing Agreement, Lender shall notify
Custodian not to deliver any USM Common Shares that are subject to such
notice specified in Section 1.2 or 1.3 hereof pursuant to the Borrowing
Agreement and Lender shall orally notify Borrower on the date of such Request
that all or such specified portion of USM Common Shares are not then
available through the Custody Account to be loaned by Harris or borrowed by
Borrower from Harris under the Borrowing Agreement.  Lender shall confirm
such notice in writing (including by facsimile transmission) to Custodian and
Borrower by the end of the Business Day following the date of such Request.

                                      4




          1.7.  Upon receipt by Borrower of a notice provided for in Section
1.2 (provided that such notice relates to all (but not less than all) of the
USM Common Shares that do not constitute Loaned Securities) or 1.3 hereof,
Borrower shall not (i) offer, sell or deliver in settlement of any trade any
Loaned Security if such offer, sale or delivery requires, in the reasonable
opinion of Borrower's counsel, delivery (including constructive delivery (a
"Constructive Prospectus Delivery") pursuant to Rule 153, or any successor or
similar rule or regulation under the Securities Act of 1933, as amended (the
"Act")) of the Prospectus (as defined in the Registration Rights Agreement)
pursuant to the Act or the rules or regulations thereunder or (ii) deliver
any Loaned Security in connection with a Common Share Delivery Arrangement
(as defined in the Indenture, dated as of __________, 1995, between USM and
Harris, as trustee, relating to USM's Liquid Yield Option Notes due 2015 (the
"Indenture")) pursuant to the Common Share Delivery Arrangement Agreement,
dated as of ________, 1995, between USM, Borrower and Harris, as conversion
agent under the Indenture (the "Common Share Delivery Arrangement
Agreement"), if such delivery requires, in the reasonable opinion of
Borrower's counsel, delivery of the Prospectus (as defined in the Registration
Rights Agreement) pursuant to the Act or the rules or regulations thereunder, in
each case until the receipt by Borrower of a notice provided for in Section 1.4
hereof.



          1.8.  WITHOUT WAIVING ANY RIGHTS GIVEN TO LENDER HEREUNDER, IT IS
UNDERSTOOD AND AGREED THAT THE PROVISIONS OF THE SECURITIES INVESTOR
PROTECTION ACT OF 1970 MAY NOT PROTECT LENDER WITH RESPECT TO LOANED
SECURITIES HEREUNDER AND THAT, THEREFORE, THE COLLATERAL DELIVERED TO HARRIS
UNDER THE BORROWING AGREEMENT MAY CONSTITUTE THE ONLY SOURCE OF SATISFACTION
OF BORROWER'S OBLIGATIONS IN THE EVENT BORROWER FAILS TO RETURN THE LOANED
SECURITIES.



          2.   FEES FOR LOANS.  Borrower shall pay Harris a monthly fee in
arrears for Loans, such fee to equal 20 basis points, on a per annum basis,
of the average daily market value of all Loaned Securities (as calculated
pursuant to Section 2 of the Borrowing Agreement) outstanding during such
month, which fee shall be the sole amount of compensation payable by Borrower
to Harris or Lender for borrowing USM Common Shares pursuant to the Borrowing
Agreement and this Agreement.  Borrower shall provide Lender and Custodian
with a written confirmation of such basis of compensation and the calculation
thereof.  Any fee payable hereunder shall be payable by Borrower to Harris
(i) within 10 days of the end of the month for which the fee was incurred, or
(ii) immediately, in the event of a default hereunder or under the Borrowing
Agreement by Borrower.

          3.   TERMINATION OF THE LOAN.  Unless otherwise agreed and subject
to the terms of the Borrowing Agreement, Borrower may terminate a Loan of
Loaned Securities under the Borrowing


                                      5



Agreement in accordance with the terms of the Borrowing Agreement, and Lender
may terminate a Loan made to Borrower pursuant to the Borrowing Agreement
upon three Business Days' notice to Borrower.  Lender shall exercise such
right to terminate a Loan made to Borrower pursuant to the Borrowing
Agreement (or to exercise any remedies for Borrower's failure to deliver such
Loaned Securities or cause such Loaned Securities to be credited to Harris'
account in accordance with the terms of the following sentence) by
instructing Harris to terminate such Loan (or to exercise such remedies) in
accordance with the terms of the Borrowing Agreement pursuant to the terms of
the Securities Loan Termination Agreement dated as of _____, 1995 among
Lender, Harris and Borrower (the "Securities Loan Termination Agreement.")
Unless otherwise agreed and subject to the terms of the Borrowing Agreement,
Borrower shall, on or before such termination date, deliver such Loaned
Securities to Harris, or cause the Loaned Securities to be credited to
Harris' account at a central depository clearing system; provided, however,
that, notwithstanding anything to the contrary herein or in the Borrowing
Agreement, Borrower's failure to so deliver the Loaned Securities or so cause
the Loaned Securities to be so credited on or before such termination date
shall not constitue a default hereunder or an Event of Default under the
Borrowing Agreement, nor give rise to any of the remedies permitted pursuant
to Section 8, 9 or 12 of the Borrowing Agreement, if such failure is caused
by the Borrower's inability to acquire such Loaned Securities, in the
reasonable opinion of counsel to Borrower, in compliance with applicable law,
including, without limitation, Rule 10b-6 (or any sucessor or similar rule or
regulation) under the Securities Exchange Act of 1934, as amended, unless
such failure shall continue for a period of more than 10 days from the date
of Harris' notice to Borrower terminating such Loan. In the circumstances
described in the proviso in the preceding sentence, the Loan shall not
terminate on the date called for in Harris' notice, but shall terminate on
such later date upon which Borrower shall have delivered such Loaned
Securities or caused such Loaned Securities to be credited to Harris' account
as provided above.

          4.   RIGHTS OF BORROWER IN RESPECT OF THE LOANED SECURITIES.  Until
a Loan is terminated in accordance herewith and with the Borrowing Agreement,
the Securities Loan Termination Agreement and the Customer Agreement and
subject to the terms of the Borrowing Agreement, Borrower shall have all the
incidents of ownership of the Loaned Securities, including, without limitation,
the right to transfer the Loaned Securities to any purchaser (as defined in the
New York Uniform Commercial Code) free of any adverse claim (as defined in
Article 8 in the New York Uniform Commercial Code).  Lender hereby waives the
right to vote the Loaned Securities during the term of the Loan.
