                       UNITED STATES CELLULAR CORPORATION
                        EXECUTIVE DEFERRED COMPENSATION
                                   AGREEMENT
 
    THIS AGREEMENT, entered into this 31(st) day of December, 1997, by and
between Joyce Gab Kneeland, (hereinafter referred to as "Executive") and United
States Cellular Corporation, (hereinafter referred to as "Company"), a Delaware
corporation, located at 8410 West Bryn Mawr Avenue, Suite 700, Chicago, IL,
60631-3486.
 
                              W I T N E S S E T H:
 
    WHEREAS, the Executive is now and will in the future be rendering valuable
services to the Company, and the Company desires to ensure the continued
loyalty, service and counsel of the Executive; and
 
    WHEREAS, the Executive desires to defer a portion of his or her salary and
bonus until retirement, resignation, disability or death, or to a specific date
greater than one year from the date of this agreement.
 
    NOW, THEREFORE, in consideration of the covenants and agreements herein set
forth, and for other good and valuable consideration, the receipt of which is
hereby acknowledged, the parties hereto covenant and agree as follows:
 
1.  Deferred Compensation Agreement. The Company agrees to establish and
    maintain a book reserve (the "Deferred Compensation Account") for the
    purpose of measuring the amount of deferred compensation payable under this
    Agreement. Credits shall be made to the Deferred Compensation Account as
    follows:
 
    (a) On each issuance of the Executive's semi-monthly payroll check,
       (scheduled for the 15th and the last day of each month), during the
       Executive's continued active employment with the Company, there shall be
       deducted an amount equivalent to 3 percent of the Executive's gross
       compensation for the pay period which will be credited to the Deferred
       Compensation Account. The first deduction will occur on the Executive's
       semi-monthly payroll check dated January 31. The deferral percentage
       selected by the Executive will also be applied to all normal bonus
       payments.
 
    (b) Commencing on February 28, 1998, and on the last day of each month
       thereafter during the Executive's continued employment with the Company,
       there shall be credited to the Deferred Compensation Account (before any
       amount is credited for the month then ending pursuant to paragraph 1(a)),
       interest compounded monthly computed at a rate equal to one-twelfth
       ( 1/12) of the sum of (a) the average thirty (30) year Treasury Bond rate
       of interest (as published in the Wall Street Journal for the last day of
       the preceding month) plus (b) 1.25 percentage points. Quarterly reports
       which specify the amount credited to the Executive's Deferred
       Compensation Account during the previous period (amount deferred plus
       interest) and the then current balance, shall be provided to the
       Executive.
 
    (c) The Deferred Compensation percentage elected in section 1(a) shall be
       deducted and credited to the Deferred Compensation Account for all
       compensation paid to the Executive, including bonus and retroactive pay
       increases.
 
    (d) The Executive may terminate participation in the Agreement with respect
       to the deferral of future compensation at any time. In the event the
       Executive elects to make such a discontinuance, he or she shall remain
       eligible to receive the benefits under Section 2 with respect to amounts
       already deferred. Previously deferred amounts are not payable until
       retirement, resignation, disability, death or the date specified by the
       Executive in paragraph 2 (g) (ii). After a discontinuance, Executive may
       not again elect to participate with respect to future deferrals until a
       subsequent calendar year.
 
                                       2

    (e) The Deferred Compensation percentage selected in 1(a) shall be in effect
       for the entire plan year unless participation is terminated. The
       Executive may not elect to change the percentage until a new plan year
       commences.
 
2.  Payment of Deferred Compensation.
 
    (a) In the event the Executive terminates his/her employment for whatever
       reason, the Company must compute the "Ending Balance" in the Deferred
       Compensation Account. This Ending Balance shall include all deferrals and
       interest as of the last day of the preceding month, and any deferrals
       made in the current month. In the event that the Executive becomes
       disabled, his/her employment shall for these purposes be deemed to
       terminate on the first day of the month in which he/she begins to receive
       long term disability payments provided by the Company's insurance carrier
       (thus, the Ending Balance shall be computed as of the preceding month).
       Payment of deferred compensation under these events will be in accordance
       with the Executive's payment method election in paragraph 2(e).
 
    (b) The Executive must elect the payment method for receiving his/her Ending
       Balance either in a lump sum or in an indicated number of installments.
       This determination must be made at the time of execution of the agreement
       in Section 2(e) and will apply to all deferrals. Any amendment changing
       the method of payment must be made at least two (2) years prior to the
       selected payment date or (2) years prior to termination of employment,
       whichever occurs first, to be considered effective.
 
    (c) In the event the Executive chooses the installment option, the Executive
       must inform the Company of the number of installments he or she wishes to
       receive. The installments will be paid quarterly (not to exceed 20
       quarters) commencing with the fifteenth day of the quarter following the
       quarter in which the date specified in 2(g) occurs. Installments will
       then be paid on the fifteenth day of each succeeding calendar quarter
       until the Ending Balance and all accrued interest, which includes
       interest earned during the installment period, has been paid. If the
       Executive chooses the lump sum option, such sum must be paid within
       forty-five (45) days after the date specified in 2(g).
 
    (d) If the Executive dies prior to the total distribution of the Ending
       Balance, the Company shall pay an amount equal to the then current
       balance including accrued interest in the Deferred Compensation Account,
       in a lump sum within forty-five (45) days following the Executive's death
       to the Executive's Designated Beneficiary (as hereinafter defined).
       However, if the Executive is married at the time of death, the Executive
       may designate (at the time of entering this Agreement or upon a
       subsequent marriage) that the payments specified in 2(c) shall continue
       to the spouse. If such spouse dies before all payments are made, the
       procedures in 3(a) and 3(b) shall apply.
 
    (e) Payment of Deferred Compensation Election (choose one option):
 
       i)  / / Lump sum distribution; or
 
       ii) /X/ Installment method. The amount of each installment shall be equal
               to one-twelfth (cannot be less than one-twentieth) of the Ending
               Balance plus accrued interest compounded monthly for the
               preceding calendar quarter.
 
    (f)  The Executive must elect the deferral date for receiving his/her Ending
       Balance. This date is to be either retirement, or a specific date greater
       than one year from the date of this agreement. This determination must be
       made at the time of execution of the agreement in Section 2(g) and will
       apply to all deferrals.
 
    (g) Election of Deferral Date (choose one option):
 
       i)  / / Retirement; or
 
       ii) /X/ Specific Date: 2010 (must be greater than one year from the date
               of this agreement)
 
                                       3

    (h) In the event of an unforeseeable emergency, the Executive may make
       withdrawals from the Deferred Compensation Account in an amount equal to
       that which is reasonably necessary to satisfy the emergency. An
       unforeseeable emergency means a severe financial hardship to the
       Executive resulting from a sudden and unexpected illness or accident of
       the Executive or of a dependent (as defined in Internal Revenue Code
       Section 152(a)) of the Executive, loss of the Executive's property due to
       casualty, or other similar extraordinary and unforeseeable circumstances
       arising as a result of events beyond the control of the Executive. The
       circumstances that will constitute an emergency will depend upon the
       facts of each case, but, in any case, payment may not be made to the
       extent that such hardship is or may be relieved (a) through reimbursement
       or compensation by insurance or otherwise; (b) by liquidation of the
       Executive's assets, to the extent the liquidation of such assets would
       not itself cause severe financial hardship; or (c) by cessation of
       deferrals under this Agreement. Examples of what are not considered to be
       unforeseeable emergencies include the need to send an Executive's child
       to college or the desire to purchase a home.
 
       In the event the Company approves the payment of a withdrawal due to an
       unforeseeable emergency, such payment shall be made by the Company to the
       Executive in a lump sum within forty-five (45) days after approval of
       such request.
 
3.  Designation of Beneficiaries.
 
    (a) The Executive may designate a beneficiary to receive any amount payable
       pursuant to paragraph 2(c) (the "Designated Beneficiary") by executing or
       filing with the Company during his/her lifetime, a Beneficiary
       Designation in the form attached hereto. The Executive may change or
       revoke any such designation by executing and filing with the Company
       during his/her lifetime a new Beneficiary Designation. If the Executive
       is married and names someone other than his/her spouse (e.g., child) as
       beneficiary, the spouse must consent by signing the designated area of
       the Beneficiary Designation form in the presence of a Notary Public.
 
    (b) If any Designated Beneficiary predeceases the Executive, or if any
       corporation, partnership, trust or other entity which is a Designated
       Beneficiary is terminated, dissolved, becomes insolvent, is adjudicated
       bankrupt prior to the date of the Executive's death, or if the Executive
       fails to designate a beneficiary, then the following persons in the order
       set forth below shall receive the entire amount specified in paragraph
       2(c) above, which the previous Designated Beneficiary would have been
       entitled to receive:
 
         i) Executive's spouse, if living; otherwise
 
         ii) Executive's then living descendants, per stirpes; and otherwise;
 
        iii) Executive's estate
 
4.  Miscellaneous.
 
    (a) The right of the Executive or any other person to any payment of
       benefits under this Agreement may not be assigned, transferred, pledged
       or encumbered.
 
    (b) If the Company finds that any person to whom any amount is payable under
       this Agreement is unable to care for his/her affairs because of illness
       or accident, or is under any legal disability which prevents the
       Executive from caring for his or her affairs, any payment due (unless a
       prior claim therefor shall have been made by a duly appointed guardian,
       committee or other legal representative) may be made to the spouse, a
       child, a parent, or a brother or sister of such person, or to any party
       deemed by the Company to have incurred expenses for such person otherwise
       entitled to payment, in such manner and proportions as the Company may
       determine. Any such lump sum payment, as discussed in 2(d), shall be a
       complete discharge of the liability of the Company under this Agreement
       for such payment.
 
                                       4

    (c) This Agreement shall be construed in accordance with and governed by the
       laws of the State of Illinois.
 
    (d) The Executive is considered to be a general unsecured creditor of the
       Company with regard to the deferred compensation amounts to which this
       Agreement pertains.
 
    (e) The deferred amounts under this Agreement are unfunded for tax and ERISA
       purposes.
 
    (f)  The Company must deduct from all payments made hereunder all applicable
       federal or state taxes required to be withheld from such payments.
 
    (g) This Agreement contains the entire understanding of the Company and the
       Executive with respect to the subject matter hereof.
 
    (h) In the event any provision of this Agreement is held illegal or invalid
       for any reason, the illegality or invalidity shall not affect the
       remaining parts of the Agreement, and the Agreement must be construed and
       enforced as if the illegal or invalid provision had not been included.
 
    IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the date first above written.
