The Award is granted pursuant to the provisions of the United States Cellular Corporation 2022 Long-Term Incentive Plan, as amended from time to time (the “Plan”) and is subject to the restrictions, terms and conditions set forth below. Capitalized terms not defined herein shall have the meanings specified in the Plan.

The Award shall become null and void unless the Employee accepts the Award and this Award Agreement electronically by utilizing the Employee’s Company on-line account with Shareworks, which is accessed at www.shareworks.com/login.

(a) In General. If Except as otherwise provided in this Award Agreement, the Restriction Period with respect to one-third of the shares of Common Stock subject to the Award on the Grant Date shall terminate on each of the first, second and third annual anniversaries of the Grant Date (each such date on which the Restriction Period terminates, a “Vesting Date”), provided that the Employee remains continuously employed by the Employers and Affiliates until the applicable Vesting Date. Within sixty (60) days following the applicable Vesting Date, the Company shall issue to the Employee in a single payment the shares of Common Stock subject to the Award that have ceased to be subject to the Restriction Period as of such date.

(b) Death. If the Employee terminates employment with the Employers and Affiliates prior to the applicable Vesting Date by reason of death, then on the date of the Employee’s death the portion of the Award outstanding at that time shall become nonforfeitable and the Restriction Period with respect to such portion of the Award shall terminate. Within sixty (60) days following the date of the Employee’s death, the Company shall issue to the Employee’s designated beneficiary in a single payment the shares of Common Stock subject to the Award at that time.

(c) Disability. If the Employee terminates employment with the Employers and Affiliates prior to the applicable Vesting Date by reason of Disability, then on the date of the Employee’s termination of employment the portion of the Award outstanding at that time shall become nonforfeitable and the Restriction Period with respect to such portion of the Award shall terminate. The Company shall issue the shares of Common Stock subject to the Award at that time in a single payment within sixty (60) days following the date of the Employee’s termination of employment; provided, however, that if the Award is subject to section 409A of the Code, and if the Employee is a Specified Employee as of the date of his or her termination of employment, then such payment shall be delayed until and made during the seventh calendar month following the calendar month during which the Employee’s termination of employment occurs (or, if earlier, the calendar month following the calendar month of the Employee’s death). For purposes of this Award Agreement, “Disability” shall mean a disability within the meaning of the long-term disability plan of the Employee’s Employer, as determined by the disability insurer of such plan.

(d) Retirement at or after Attainment of Age 66. If the Employee terminates employment with the Employers and Affiliates on or after January 1, 2024 but prior to the applicable Vesting Date by reason of retirement at or after attainment of age 66, then on the date of the Employee’s termination of employment the portion of the Award outstanding at that time shall become nonforfeitable and the Restriction Period with respect to such portion of the Award shall terminate. The Company shall issue the shares of Common Stock subject to the Award at that time in a single payment within sixty (60) days following the date of the Employee’s termination of employment; provided, however, that if the Award is subject to section 409A of the Code, and if the Employee is a Specified Employee as of the date of his or her termination of employment, then such payment shall be delayed until and made during the seventh calendar month following the calendar month during which the Employee’s termination of employment occurs (or, if earlier, the calendar month following the calendar month of the Employee’s death). If the Employee terminates employment with the Employers and Affiliates prior to January 1, 2024 by reason of retirement at or after attainment of age 66, then on the date of the Employee’s termination of employment the Award (to the extent then outstanding) shall be forfeited and shall be canceled by the Company.

(e) Other Termination of Employment. If the Employee terminates employment with the Employers and Affiliates prior to the applicable Vesting Date for any reason other than death, Disability or retirement at or after attainment of age 66 (including if the Employee’s employment is terminated prior to the applicable Vesting Date by reason of the Employee’s negligence or willful misconduct, in each case as determined by the Company in its sole discretion, irrespective of whether such termination occurs on or after the Employee attains age 66), then on the date of the Employee’s termination of employment the Award (to the extent then outstanding) shall be forfeited and shall be canceled by the Company.

(f) Forfeiture of Award and Award Gain upon Competition, Misappropriation, Solicitation or Disparagement. Notwithstanding any other provision herein, if the Employee engages in (i) Competition (as defined in this Section 2(f) below); (ii) Misappropriation (as defined in this Section 2(f) below); (iii) Solicitation (as defined in this Section 2(f) below) or (iv) Disparagement (as defined in this Section 2(f) below), in each case as determined by the Company in its sole discretion, then (i) on the date of such Competition, Misappropriation, Solicitation or Disparagement, the Award immediately shall be forfeited and shall be canceled by the Company and (ii) in the event that any portion of the Award became nonforfeitable within the twelve months immediately preceding such Competition, Misappropriation, Solicitation or Disparagement, the Employee shall pay the Company, within five business days of receipt by the Employee of a written demand therefore, an amount in cash determined by multiplying the number of shares of Common Stock subject to the portion of the Award that became nonforfeitable within such period (without reduction for any shares of Common Stock withheld by the Company pursuant to Section 4.3) by the Fair Market Value of a share of Common Stock on the date that such portion of the Award was paid. The Employee acknowledges and agrees that the Award, by encouraging stock ownership and thereby increasing an employee’s proprietary interest in the Company’s success, is intended as an incentive to participating employees to remain in the employ of the Employers or an Affiliate. The Employee acknowledges and agrees that this Section 2(f) is therefore fair and reasonable, and not a penalty.

The Employee may be released from the Employee’s obligations under this Section 2(f) only if and to the extent the Committee determines in its sole discretion that such release is in the best interests of the Company.

The Employee agrees that by accepting this Award Agreement the Employee authorizes the Employers and any Affiliate to deduct any amount owed by the Employee pursuant to this Section 2(f) from any amount payable by the Employers or any Affiliate to the Employee, including, without limitation, any amount payable to the Employee as salary, wages, vacation pay or bonus as allowed under state law. The Employee further agrees to execute any documents at the time of setoff required by the Employers and any Affiliate in order to effectuate the setoff. This right of setoff shall not be an exclusive remedy (the Company shall be entitled to any other remedy permitted under applicable law) and an Employer’s or an Affiliate’s election not to exercise this right of setoff with respect to any amount payable to the Employee shall not constitute a waiver of this right of setoff with respect to any other amount payable to the Employee or any other remedy. Should the Company institute a legal action against the Employee to recover the amounts due, the Employee agrees to reimburse the Company for its reasonable attorneys’ fees and litigation costs incurred in recovering such amounts from the Employee.

For purposes of this Award Agreement, “Competition” shall mean that the Employee, directly or indirectly, individually or in conjunction with any Person, during the Employee’s employment with the Employers and the Affiliates and for the twelve months after the termination of that employment for any reason, other than on any Employer’s or Affiliate’s behalf (i) has contact with, or provides any information to a third party in connection with its or their direct or indirect solicitation of, any customer or prospective customer of an Employer or Affiliate with whom the Employee had contact during the one year period immediately prior to termination of the Employee’s employment which has been contacted or solicited by or on behalf of an Employer or Affiliate, for the purpose of soliciting or selling to such customer or prospective customer the same or a similar (such that it could substitute for) product or service provided by an Employer or Affiliate during the Employee’s employment with the Employers and Affiliates; or (ii) works for any wireless service carrier in the same or similar role for which the Employee worked for any Employer or Affiliate or which may require utilizing any Confidential Information (as defined below) acquired while employed by any Employer or Affiliate in any market within the continental United States in which an Employer or Affiliate provided such products or services during the Employee’s employment with an Employer or Affiliate or had plans to do so within the twelve month period immediately following the Employee’s termination of employment. For purposes of the foregoing, “wireless carrier” includes any wireless carrier holding a license granted by the Federal Communications Commission, as well as any reseller or mobile virtual network operator (MVNO). “Work for” includes the provision of services, whether paid or unpaid, as an employee, officer, director, consultant or advisor.

For purposes of this Award Agreement, “Misappropriation” shall mean that the Employee (i) uses Confidential Information (as defined below) for the benefit of anyone other than the Employers or an Affiliate, as the case may be, or discloses the Confidential Information to anyone not authorized by the Employers or an Affiliate, as the case may be, to receive such information; (ii) upon termination of employment, makes any summaries of, takes any notes with respect to or memorizes any Confidential Information or takes any Confidential Information or reproductions thereof from the facilities of the Employers or an Affiliate or (iii) upon termination of employment or upon the request of the Employers or an Affiliate, fails to return all Confidential Information then in the Employee’s possession. For the avoidance of doubt, “Misappropriation” does not include disclosure of Confidential Information to a governmental regulatory agency, such as the U.S. Securities and Exchange Commission, or to an attorney, provided that the Employee informs the agency or attorney that the Employers and/or Affiliates deem the information to be confidential. Additionally, in the event the Employee files a lawsuit against the Employer for retaliation by the Employer against the Employee for reporting a suspected violation of law, the Employee has the right to provide trade secret information to their attorney and use the trade secret information in the court proceeding, although the Employee must file any document containing the trade secret under seal and may not disclose the trade secret, except pursuant to court order.

“Confidential Information” shall mean any information that the Employee learns or developed during the course of employment with an Employer or Affiliate that gives the Employer or any Affiliate a commercial advantage over a competitor that does not have such information and/or information that is not generally known to Persons outside the Employer or Affiliate, regardless of whether it is labeled confidential. Such information includes, but is not limited to, any confidential and proprietary drawings, reports, sales and training manuals, customer lists, computer programs and other material embodying trade secrets or confidential technical, business, or financial information of any Employer or an Affiliate. Confidential Information also includes information of third parties for which an Employer or Affiliate has accepted obligations of confidentiality. Nothing in this Award Agreement is intended to prohibit the Employee from disclosing or discussing wages, hours and/or other terms and conditions of employment, which may be subject to an enforceable non-disclosure or confidentiality obligation pursuant to some other contract, policy, or arrangement or applicable law.

For purposes of this Award Agreement, “Solicitation” shall mean that the Employee, directly or indirectly, individually or in conjunction with any Person, during the Employee’s employment with the Employers and the Affiliates and for the twelve months after the termination of that employment for any reason, other than on any Employer’s or Affiliate’s behalf, solicits, induces or encourages (or attempts to solicit, induce or encourage) any individual away from any Employer’s or Affiliate’s employ or from the faithful discharge of such individual’s contractual and fiduciary obligations to serve the Employers’ and Affiliates’ interests with undivided loyalty.

For purposes of this Award Agreement, “Disparagement” shall mean that the Employee has made a material statement (whether oral, written or electronic), or released any material information or encouraged others to make such a statement or release such information, to any Person other than to an officer of an Employer or an Affiliate that is designed to embarrass, disparage or demean an Employer, any Affiliate, or any of their respective owners, directors, officers, employees, products or services. For the avoidance of doubt, “Disparagement” does not include making truthful statements (i) when required by legal process to do so by a court of law, (ii) to any governmental agency having supervisory authority over the business of an Employer, or (iii) when required by any administrative or legislative body (including a committee thereof) with the jurisdiction to order the Employee to divulge, disclose or make accessible such information.

3. Change in Control. The treatment of the Award in connection with a Change in Control shall be governed by Section 7.9 of the Plan.

4.1. Transferability of Award. Except (i) to a beneficiary upon the Employee’s death (as designated in such form prescribed by the Company or pursuant to the terms of the Plan, and which may be designated on both a primary and contingent basis) or (ii) pursuant to a court order entered in connection with a dissolution of marriage or child support, the Award may not be sold, transferred, assigned, pledged, hypothecated, encumbered or otherwise disposed of (whether by operation of law or otherwise) or be subject to execution, attachment or similar process. Upon any attempt to so sell, transfer, assign, pledge, hypothecate, encumber or otherwise dispose of the Award, the Award and all rights hereunder shall immediately become null and void.

4.2. Investment Representation. The Employee hereby represents and covenants that (a) any shares of Common Stock acquired upon the lapse of restrictions with respect to the Award will be acquired for investment and not with a view to the distribution thereof within the meaning of the Securities Act of 1933, as amended (the "Securities Act"), unless such acquisition has been registered under the Securities Act and any applicable state securities laws; (b) any subsequent sale of any such shares shall be made either pursuant to an effective registration statement under the Securities Act and any applicable state securities laws, or pursuant to an exemption from registration under the Securities Act and such state securities laws; and (c) if requested by the Company, the Employee shall submit a written statement, in a form satisfactory to the Company, to the effect that such representation is true and correct as of the date of acquisition of any shares hereunder or is true and correct as of the date of sale of any such shares, as applicable. As a condition precedent to the issuance or delivery to the Employee of any shares subject to the Award, the Employee shall comply with all regulations and requirements of any regulatory authority having control of or supervision over the issuance or delivery of the shares and, in connection therewith, shall execute any documents which the Committee shall in its sole discretion deem necessary or advisable.

4.3. Tax Withholding. The Employee timely shall pay to the Company such amount as the Company may be required, under all applicable federal, state, local or other laws or regulations, to withhold and pay over as income or other withholding taxes (the "Required Tax Payments") with respect to the Award. The Required Tax Payments shall be satisfied by the Company withholding whole shares of Common Stock which otherwise would be delivered to the Employee pursuant to the Award, having an aggregate Fair Market Value determined as of the date the obligation to withhold or pay taxes arises in connection with the Award. Shares of Common Stock to be withheld may not have an aggregate Fair Market Value in excess of the amount determined by applying the minimum statutory withholding rate; provided, however, that the number of shares to be withheld to satisfy the Required Tax Payments shall be rounded up to the nearest whole share, and the Company shall reimburse the Employee in cash for any such excess tax withholding as soon as practicable thereafter.

Notwithstanding the foregoing provisions of this Section 4.3, an Employee may satisfy his or her obligation to advance employment taxes owed prior to the date that the Restriction Period with respect to the Award terminates, if any, by a cash payment to the Company, and the Employee hereby authorizes the Company or any Affiliate to deduct such cash payment from any amount payable by the Company or such Affiliate to the Employee, including without limitation any amount payable to the Employee as salary or wages. The Employee agrees that this authorization may be reauthorized via electronic means determined by the Company, and that the Employee may revoke this authorization by written notice to the Company prior to any such deduction.

4.4. Award Confers No Rights as a Stockholder. The Employee shall not be entitled to any privileges of ownership with respect to the shares of Common Stock subject to the Award unless and until the restrictions on the Award lapse and the shares are issued and the Employee becomes a stockholder of record with respect to such shares.

4.5. Adjustment. In the event of any equity restructuring (within the meaning of Financial Accounting Standards Board Accounting Standards Codification Topic 718, Compensation—Stock Compensation or any successor or replacement accounting standard) that causes the per share value of shares of Common Stock to change, such as a stock dividend, stock split, spinoff, rights offering or recapitalization through an extraordinary cash dividend, the terms of the Award, including the number and class of securities subject to the Award, shall be appropriately adjusted by the Committee. In the event of any other change in corporate capitalization, including a merger, consolidation, reorganization or partial or complete liquidation of the Company, such adjustment described in the foregoing sentence may be made as determined to be appropriate and equitable by the Committee to prevent dilution or enlargement of rights of participants. In either case, the decision of the Committee regarding any such adjustment shall be final, binding and conclusive.

4.6. Compliance with Applicable Law. The Award is subject to the condition that if the listing, registration or qualification of the shares of Common Stock subject to the Award upon any securities exchange or under any law, the consent or approval of any governmental body or the taking of any other action is necessary or desirable as a condition of, or in connection with, the delivery of shares, such shares will not be delivered unless such listing, registration, qualification, consent, approval or other action shall have been effected or obtained, free of any conditions not acceptable to the Company. The Company agrees to use reasonable efforts to effect or obtain any such listing, registration, qualification, consent, approval or other action.

4.7. Delivery of Shares. On the date of payment of the Award, the Company shall deliver or cause to be delivered to the Employee the shares of Common Stock subject to the Award. The holder of the Award shall pay all original issue or transfer taxes and all fees and expenses incident to such delivery, unless the Company in its discretion elects to make such payment.

4.8. Award Confers No Rights to Continued Employment or Service. In no event shall the granting of the Award or the acceptance of this Award Agreement and the Award by the Employee give or be deemed to give the Employee any right to continued employment by or service with any Employer or any subsidiary or affiliate of an Employer.

4.9. Decisions of Committee. The Committee or its delegate shall have the right to resolve all questions which may arise in connection with the Award.
