Amended and Restated T-Mobile US, Inc. Non-Qualified Deferred Executive Compensation Plan

This Non-Qualified Deferred Compensation Plan is intended to promote and advance the interests of T-Mobile US, Inc. (the “Company”) and its wholly owned subsidiaries by stimulating the efforts of select key executives of the Company. The Plan was originally effective January 1, 2008 and was subsequently amended and restated effective January 1, 2014. Now, effective July 15, 2024, the Plan is hereby amended and restated to revise the rules applicable to Deferral Elections and times and forms of payment, and to make certain other changes.

Benefits under the Plan are intended to provide a source of deferred compensation available on an in-service or retirement basis for eligible executives in addition to their retirement savings under the Qualified Plan(s) in which they are eligible to participate. To achieve this result, the Plan provides Participants the opportunity to defer a portion of their annual Base Salary, Performance Bonus and RSU Awards, including time-vesting, performance-vesting, settled in Common Stock and settled in cash RSU Awards, along with the right of the Company to make individual deferred compensation commitments. Vested amounts are to be made available for distribution at Participant-determined dates. The Plan is designed to serve these purposes by offering elective deferrals and discretionary Company-provided credits, and by making accumulated balances payable upon the election of the Participant.

This Plan is also intended to comply with Code Section 409A with respect to all benefits under the Plan.

“Vested” or “Vesting” shall mean the degree to which a Participant’s right to the balance in such Participant’s Account under the Plan has become non-forfeitable.

3.1Participation. Once an employee becomes an Eligible Employee and he or she receives notification of eligibility to participate from the Administrator, he or she may elect to participate in the Plan by completing a Deferral Election during the applicable initial Election Period. If a Participant ceases to be an Eligible Employee during a Plan Year, the Participant’s Deferral Election shall remain in effect for the remainder of that Plan Year but shall not continue in effect past the end of that Plan Year, and the Participant may not make a new Deferral Election for the subsequent Plan Year. The Participant’s Account shall remain subject to the terms and conditions of the Plan.

3.2Deferrals Irrevocable and Non-assignable. All amounts credited to a Participant’s Account, including elective deferrals and Company allocations, if any, shall be treated as having been irrevocably credited, and no payment based on such amounts may be received except in accordance with the terms and conditions of this Plan. Notwithstanding any provision in this Plan to the contrary, if it is determined that any amounts credited under this Plan are currently or retrospectively taxable under the Code, such amounts will be paid out in a lump sum upon such determination.

Neither the Participant nor any Beneficiary shall have any right or ability to alienate, sell, transfer, assign, pledge, encumber or submit to garnishment, execution or levy, either voluntarily or involuntarily, any amount due or expected to become due under this Plan. Amounts due under this Plan shall be paid, transferred, delivered or otherwise conveyed only to the Participant or the Participant’s Beneficiary.

4.1Participant Elective Deferrals.

(a)Base Salary. In such manner and form as prescribed by the Administrator, each Participant may make a Deferral Election to have any whole percentage (up to 75%) of his Base Salary withheld by the Company and credited to his Account under the Plan.

(b)Performance Bonus. In such manner and form as prescribed by the Administrator, each Participant may make a Deferral Election to have an amount (up to 100% less any legally required deductions) of his Performance Bonus withheld by the Company and credited to his Account under the Plan.

(c)RSU Award.     In such manner and form as prescribed by the Administrator, each Participant may make a Deferral Election to have an amount (up to 100% less any legally required deductions) of his RSU Award withheld by the Company and credited to his Account under the Plan.

(d)    Timing and Manner of Election. Newly Eligible Employees may enroll in the Plan during their Election Period for their initial full or partial Plan Year of participation, as specified in the notification from the Administrator. Each Plan Year thereafter, Participants will be permitted to modify the Deferral Election during each subsequent Election Period. The Deferral Election becomes irrevocable on December 31 of the Plan Year preceding the Plan Year in which the amounts are deferred and may not change throughout such subsequent Plan Year. The amount of a Participant’s Base Salary, Performance Bonus, and RSU Award, as applicable, deferred in a Participant’s Deferral Election shall continue in effect for each subsequent Plan Year, unless modified by the Participant before the date the election becomes irrevocable under this subsection (d). However, a Participant’s Deferral Election as to timing and form of payment shall not continue in effect for subsequent Plan Years; a Participant must make a new Deferral Election each Plan Year with respect to the time and form of payment for the amounts to be deferred in the subsequent Plan Year under that Deferral Election. In the absence of an affirmative election as to the timing and form of payment of a Participant’s Deferral Election for a given Plan Year, the amount deferred during that Plan Year shall be paid in a single distribution at termination of employment. A Participant whose Deferral Election is cancelled in accordance with Section 3.1 or 4.1(e) will be required to file a new Deferral Election under this Article IV in order to recommence deferrals under the Plan.

(e)Vesting of RSUs. For RSUs credited to a Participant’s Account related to a deferral of an RSU Award, such RSUs shall vest as provided under the Equity Plan or the applicable award agreement. To the extent the RSUs are not Vested, they shall be forfeited.

4.2Discretionary Company Allocations. The Company may, from time to time in its sole and absolute discretion, credit Company discretionary allocations to any Participant in any amount determined by the Company. Such contributions shall be credited to a Participant’s Account. Company allocations shall vest in accordance with the vesting schedule(s) established by the Administrator at the time that the Company allocations are made. The portion of a Participant’s Account that remains unvested upon his or her termination of employment after the application of the terms of this Section 4.2 shall be forfeited. Any Vested Company discretionary allocations shall be paid in a single lump sum at termination of employment.

5.1Accounts. All Participant deferrals and Company allocations, if any, shall be credited to the Participant’s Account. A Participant’s Account is a bookkeeping device to track the amount of deferrals, Company allocations, if any, and earnings with respect thereto. No assets shall be reserved or segregated in connection with any Account, and no Account shall be insured or otherwise secured.

Notwithstanding the foregoing, in the event a Participant has requested that his or her Account be invested in a particular way, then to the extent such request has been honored, the income or loss attributable to such Participant’s Account shall be determined solely on the basis of the performance of the designated investment portfolio.

(a)Deferral of Cash Amounts. Any cash compensation and any RSUs settled in cash deferred by a Participant shall be credited to the cash subaccount of the Participant’s Account. The cash-settled RSUs shall be credited to the Participant’s cash subaccount as of the date the RSUs would otherwise have been awarded under the Equity Plan.

(b)Deferral of RSUs. Any RSUs settled in Common Stock deferred by a Participant shall be credited to the RSU subaccount of the Participant’s Account in the number of RSUs (including fractional units) under the RSU Award being deferred. The Common Stock-settled RSUs shall be credited to the Participant’s RSU subaccount as of the date the RSUs would otherwise have been awarded under the Equity Plan.

5.2Investment of Accounts.

(a)Cash Subaccounts. The portion of a Participant’s Account maintained in dollars shall be deemed to be invested in the investment options that are selected by the Participant, in the percentages as elected by the Participant for each Account. The Administrator shall determine and communicate to Participants the investment options available under the Plan; provided, however, that Common Stock shall not be an investment option. If the Participant fails to make an investment election, his or her Account(s) shall be deemed to be invested in a default investment fund specified by the Administrator. The Account(s) shall be adjusted to reflect the earnings, gains and losses, reduced by any allocable costs or expenses, such account(s) would experience had it actually been invested in the specific funds at the relevant times. Participants may change their deemed investment elections under the Plan in the form and manner prescribed by the Administrator. The Administrator or its delegate shall set forth from time to time the procedures Participants are to use in making or changing their deemed investment elections for their Accounts. A Participant change in the investment of new deferrals shall take effect as soon as administratively practicable as of a following payroll period. A Participant may change the investments of existing Account balances as of any business day, subject to any applicable inter- fund trading restrictions. The Company is not obligated to actually invest any assets in the investment funds selected by the Participant.

(b)RSU Subaccounts. The Participant’s RSU subaccount(s) shall be deemed to be invested in Common Stock of the Company. Each RSU subaccount shall be credited additional full or fractional RSUs for cash dividends paid on the Common Stock of the Company based on the number of RSUs in the RSU subaccount on the applicable dividend record date and calculated based on the Fair Market Value of the Common Stock of the Company on the applicable dividend payment date. Each RSU subaccount shall also be equitably adjusted as determined by the Administrator in the event of any stock dividend, stock split or similar change in the capitalization of the Company.

5.3Valuation of Accounts. The Administrator or its delegate shall determine the value of each Participant’s Account balance on each date that the deemed investment options available under the Plan are valued by the managers of such investment options, and the value of the deemed investment earnings, gains and losses on Participant deferrals and Company allocations, if any, shall be determined in the same manner and consistent with the valuations given by the managers of such investment options.

5.4Determination of Amount. The Administrator or its delegate shall verify the amount of Participant deferrals, Company allocations, if any, and earnings, gains, and losses to be credited to each Participant’s Account in accordance with the provisions of the Plan. This determination shall be final and conclusive upon all Participants and Beneficiaries hereunder, absent manifest error. As soon as administratively practicable after the close of the Plan Year quarter, the Administrator or its delegate shall send to each Participant an itemized accounting statement which shall reflect the Participant’s Account balance.

5.5No Impact on Benefit Promise. Investment of a Participant’s Account balance in the manner requested by a Participant shall not change the fact that the Company makes only an unsecured promise to pay any amounts deferred under this Plan.

6.1Initial Election of Timing and Form of Payment.

(a)Deferral Elections Effective Before January 1, 2025. Pursuant to a Deferral Election, a Participant may elect to designate that the applicable deferred amounts will be paid at termination of employment (including Retirement), Disability or on a Specified Date as follows:

(i)    Specified Date Distribution. Under a Specified Date Election, a Participant may elect to receive payment on the date selected in a single lump sum or commence on the date selected in annual installments over two to five years. Notwithstanding the foregoing, if the Participant becomes Disabled, retires, or terminates employment with the Company prior to the complete distribution of amounts subject to a Specified Date Election, payment of the Participant’s remaining amount to be paid in connection with the Specified Date Election shall be made in a single lump sum at termination of employment.

(ii)Distribution on Retirement, Disability, or other termination of employment. Under a Retirement/Disability Election, a Participant may elect to have the amounts subject to that election paid either as a lump sum distribution, or in a series of annual installments over two to fifteen years. However, in the case of a termination of employment that is not due to Retirement or Disability, an election for payment in annual installments shall not apply, and the amounts shall be paid in the form of a single lump sum.

(b)Deferral Elections Effective On and After January 1, 2025. Pursuant to a Deferral Election, a Participant may elect to designate that the applicable deferred amounts will be paid at the earlier of the date of the first payment in connection with (1) the applicable Retirement/Disability Election or (2) the applicable Specified Date Election.

(i)Specified Date Distribution. Under a Specified Date Election, a Participant may elect to receive payment on the date selected in a single lump sum or commence on the date selected in annual installments over two to five years. Notwithstanding the foregoing,

if the Participant terminates employment that is not due to Retirement or Disability prior to the complete distribution of amounts subject to a Specified Date Election, payment of the Participant’s remaining amount to be paid in connection with the Specified Date Election shall be made in a single lump sum at termination of employment.

(ii)Distribution on Retirement, Disability, or other termination of employment. Under a Retirement/Disability Election, a Participant may elect to have the amounts subject to that election paid either as a lump sum distribution, or in a series of annual installments over two to fifteen years. However, in the case of a termination of employment that is not due to Retirement or Disability, an election for payment in annual installments shall not apply, and the amounts shall be paid in the form of a single lump sum.

(c)If a Participant fails to properly elect the timing and form of payout applicable to a Deferral Election, the Participant shall be deemed to have selected a single lump sum to be made at termination of employment, except as otherwise required under this Article VI.

6.2Subsequent Elections. The Participant may make a subsequent election regarding the form or timing of payment of his Account balance, provided the election meets the following requirements:

(a)    Such election does not take effect until at least 12 months after the date on which the election is made;

(b)    In the case of an election to defer payment, the first or sole payment pursuant to such election is made not less than five (5) years from the date such payment would otherwise have been made, except that this requirement does not apply to payments relating to death or Unforeseeable Emergency; and

(c)    The election is made a minimum of 12 months prior to the date on which the first scheduled payment is to be made.

For purposes of this Section, a series of installments payments is treated as a single payment to be made when the first installment would have otherwise been paid.

In the event the Participant submits a distribution payment or timing election as permitted under this Section which does not meet all the requirements set forth above, the election will be void. Accordingly, payment will be made pursuant to the terms of the Participant’s immediately preceding valid election, if applicable. If the Participant has not made a valid election, payment will be made in a single distribution upon Participant’s termination from employment with the Company.

For avoidance of doubt, a Participant may make a separate subsequent election with respect to the time or form of payment associated with (1) a Specified Date Election, (2) a Retirement/Disability Election, or (3) in the case of a Deferral Election effective before January

1, 2025, the default lump sum payable at Retirement or Disability for Specified Date Elections if payments have not yet commenced.

Notwithstanding a Participant’s election pursuant to this Section, if a Participant terminates employment for any reason other than Retirement or Disability, the entire remaining Account balance shall be paid in a single lump sum at termination of employment.

6.3Form of Payment. Distributions from a Participant’s cash subaccount(s) shall be paid in cash and, except in the case of distributions to Puerto Rico residents, distributions from his RSU subaccount balance shall be made in Common Stock for whole RSUs and cash for any fractional RSU. Any distribution from a Participant’s Account to a Puerto Rico resident shall be paid solely in cash. Any RSU or fractional RSU in the Participant’s RSU subaccount as of the applicable date which is to be paid in cash from the Plan shall be converted to cash prior to distribution based on the Fair Market Value of the Common Stock of the Company on such date.

6.4Death of Participant. If the Participant dies prior to payment of his entire Vested Account balance in the Plan, the Administrator shall direct the Company to pay the remaining Vested balance of the Participant’s Account to the Participant’s Beneficiary in a single distribution. Any designation of Beneficiary shall be made by the Participant on an election form filed with the Administrator and may be changed by the Participant only by filing another election form containing the revised instructions. If no Beneficiary is designated or no designated Beneficiary survives the Participant, the single distribution shall be made to the Participant’s estate. The Administrator may require any person claiming a Participant’s Vested Account balance as the Participant’s Beneficiary under the Plan to produce such evidence as the Administrator may deem reasonable.

6.5Change in Control. Notwithstanding a Participant’s election pursuant to Section 6.1 or 6.2, a Participant shall receive a single distribution equal to the unpaid balance of all of his or her Accounts upon a termination of employment that occurs within 24 months following a Change in Control. In addition to the foregoing, upon a Change in Control, a Participant who has incurred a Retirement or Disability prior to the Change in Control, will receive the balance of all unpaid Accounts in a single distribution. All single distributions under this Section shall be made to the respective Participants within 90 days following the termination or Change in Control, as applicable.

6.6Small Account Balances. The Administrator shall pay the value of the Participant’s Accounts upon a termination of employment in a single distribution if the balance of such Accounts is not greater than the applicable dollar amount under Code Section 402(g)(1)(B), provided the payment represents the complete liquidation of the Participant’s interest in the Plan.

6.7Acceleration of or Delay in Payments. The Administrator, in its sole and absolute discretion, may elect to accelerate the time or form of payment of a benefit owed to the Participant hereunder, provided such acceleration is permitted under Treasury Regulation Section 1.409A-3(j)(4). The Administrator may also, in its sole and absolute discretion, delay

the time for payment of a benefit owed to the Participant hereunder, to the extent permitted under Treasury Regulation Section 1.409A-2(b)(7).

6.8Alternate Payee. If the Plan receives a domestic relations order (within the meaning of Code Section 414(p)(l)(B)) directing that all or a portion of a Participant’s Accounts be paid to an “alternate payee,” any amounts to be paid to the alternate payee(s) shall be paid in a single lump sum as soon as administratively practicable following a determination that the order is qualified, unless the order specifies different payment timing.

6.9Unforeseeable Emergency Withdrawal. If a Participant suffers an Unforeseeable Emergency the Participant may request, and the Administrator may direct the Company to pay to the Participant from the elective deferral portion of his Account, the amount the Administrator determines is necessary to satisfy the emergency need, including any amounts necessary to pay federal, state or local income taxes reasonably anticipated to result from the payment. A Participant requesting an emergency payment shall apply for the payment in the form and manner prescribed by the Administrator and shall provide such additional information as the Administrator may require. If so directed by the Administrator, the amount of the emergency payment shall be subtracted first from the Vested amounts designated for payment on a Specified Date, beginning with the earliest schedule payout, until these amounts are depleted, and then from the Vested amounts designated for payment on Retirement or termination of employment. When making any such payment the Participant’s cash subaccounts shall be utilized in the order stated above until all such cash accounts have been depleted and then, as needed, Vested amounts in the Participant’s RSU subaccounts shall be utilized. Payments of Vested amounts in the RSU subaccounts shall be made in Common Stock, except that any such payment to a Participant who is a Puerto Rico resident shall be paid in cash after conversion of the RSUs to cash as described in Section 6.3.

6.10Incompetence. If the Administrator determines that a Participant or Beneficiary is unable to care for his affairs because of illness, accident or otherwise, any payment due the Participant or Beneficiary shall be made only to a duly authorized guardian or other legal representative or, upon appropriate indemnification of the Administrator, to the Spouse. Any such payment shall be a payment for the account of the Participant and shall be a complete discharge of any liability of the Company therefore.

Notwithstanding anything in the Plan to the contrary, the Company shall withhold from all benefit payments made to a Participant (or his Beneficiary) under the Plan any amount which the Company is required to withhold for any applicable local, state, or federal taxes. In the case of payments to be made in Common Stock, the Company shall withhold the minimum required number of shares of Common Stock otherwise issuable to the Participant as may be necessary to satisfy such withholding obligation.

Neither the Company nor the Administrator nor any other person or entity represents or guarantees that any particular federal, state or local tax consequences will occur as a result of any Participant’s participation in this Plan. Each Participant shall consult with his own advisers regarding the tax consequences of participation in this Plan.

The Plan may be amended or terminated by the Administrator at any time. No amendment or termination of the Plan shall, without the consent of any persons affected thereby, alter, or impair any rights created prior to such amendment or termination. If the Plan is terminated, benefits shall be paid in accordance with the terms of the Plan as in effect at the time of such termination.

Notwithstanding the foregoing, the Administrator shall have discretion, on termination, to accelerate payment of Vested benefits in the following circumstances: (1) within twelve (12) months of a corporate dissolution taxed under Code Section 331, or with the approval of a bankruptcy court pursuant to 11 U.S.C. 503(b)(1)(A), so long as the amounts deferred under the Plan are included in the Participant’s or Beneficiary’s gross income in the latest of the calendar year in which the termination occurs, the calendar year in which the amount is no longer subject to a substantial risk of forfeiture, or the first calendar year in which payment is administratively practicable; (2) within the thirty (30) day period preceding or the twelve (12) months following a Change in Control event; or (3) all arrangements of the same type as this Plan (that is, arrangements which are required to be aggregated under Treasury Regulation Section 1.409A-1(c)(2) if the Participant participated in all of the arrangements) are terminated, only amounts payable absent a termination of the Plan are paid within twelve (12) months of the termination, all payments are made within twenty-four (24) months of the termination, and a new arrangement of the same type is not adopted at any time for a period of three years following the date of the termination.

9.1Plan Administration. The Plan shall be administered by the Administrator. The Administrator or its delegate has exclusive power to interpret the Plan and may from time to time make such decisions and adopt such rules and regulations for implementing the Plan as it deems appropriate. In so administering the Plan, the decisions and actions of the Administrator or its delegate shall be final and binding on all parties with respect to all matters relating to the Plan. A Participant shall not be entitled to examine, audit, or otherwise have access to any financial statements, bookkeeping records or other records of account pertaining to the Company or the Plan under any circumstances whatsoever.

9.2Expenses. All expenses and costs in connection with the adoption and administration of the Plan shall be borne by the Company.

9.3Maintenance of Separate Accounts. The Administrator or its designee will create and maintain adequate records to disclose all Participants’ Account bookkeeping entries. Such records shall be in the form of individual Account ledgers, and credits to and payments from an Account shall be reflected therein. The maintenance of individual Account bookkeeping entries for Participants is only for accounting purposes and no segregation of assets from the general assets of the Company to each Account shall be required. Each payment made from an Account shall be charged to the Account as of the date paid.

9.4Administration Upon Change in Control. Upon a Change in Control, the individual who was the Chief Executive Officer of the Company (or if such person is unable or unwilling to act, the next highest-ranking officer) prior to the Change in Control shall have the authority (but shall not be obligated) to appoint an independent third party to act as the Administrator.

Upon such Change in Control, the Company may not remove the Administrator appointed as provided above under this Section 9.4, unless 2/3rds of the members of the Board of Directors of the Company and a majority of Participants and Beneficiaries with Account balances consent to the removal and replacement Administrator. Notwithstanding the foregoing, neither the Administrator so appointed nor the officer described above shall have authority to direct investment of trust assets under any rabbi trust described in Section 11.2.

The Company shall, with respect to the Administrator appointed as provided above under this Section 9.4, (i) pay all reasonable expenses and fees of the Administrator, (ii) indemnify the Administrator (including individuals serving as Administrator) against any costs, expenses and liabilities including, without limitation, attorneys’ fees and expenses arising in connection with the performance of the Administrator hereunder, except with respect to matters resulting from the Administrator’s gross negligence or willful misconduct and (iii) supply full and timely information to the Administrator on all matters related to the Plan, any rabbi trust, Participants, Beneficiaries and Accounts as the Administrator may reasonably require.

9.5Indemnification. The Company shall indemnify and hold harmless each employee, officer, director, agent or organization, to whom or to which are delegated duties, responsibilities, and authority under the Plan or otherwise with respect to administration of the Plan, including, without limitation, the Administrator and its agents, against all claims, liabilities, fines and penalties, and all expenses reasonably incurred by or imposed upon him or it (including but not limited to reasonable attorney fees) which arise as a result of his or its actions or failure to act in connection with the operation and administration of the Plan to the extent lawfully allowable and to the extent that such claim, liability, fine, penalty, or expense is not paid for by liability insurance purchased or paid for by the Company.

The arbitration shall be administered by JAMS pursuant to its Streamlined Arbitration Rules and Procedures. Judgment on the award may be entered in any court having jurisdiction.

11.1Top Hat Plan. This Plan is maintained primarily to provide deferred compensation benefits for a select group of “management or highly-compensated employees” within the meaning of Sections 201, 301 and 401 of ERISA, and therefore to be exempt from the provisions of Parts 2, 3 and 4 of Title I of ERISA. Accordingly, the Plan shall terminate, and no further benefits shall accrue hereunder if it is determined by a court of competent jurisdiction or by an opinion of counsel that the Plan constitutes an employee pension benefit plan within the meaning of Section 3(2) of ERISA which is not so exempt.

11.2Source of Funding. All amounts allocated to a Participant’s Account under the Plan, together with interest or other income credited thereon pursuant to the terms of the Plan, shall be paid to the trustee of the Company’s Trust, and shall be subject to the provisions of the Trust. Trust assets shall be subject to the claims of the creditors of the Company should the Company become insolvent. Nothing contained in this Plan requires the Company to set aside or hold in trust any amounts or assets for the purpose of paying benefits to Participants. This Plan creates only a contractual obligation on the part of the Company to pay to the Participant or Beneficiary an amount equal to the Vested portion of the value of the Participant’s Account. The Participant or Beneficiary shall be no more than a general unsecured creditor of the Company with no special or prior right to any assets of the Company or the Trust for payment of any obligations hereunder. The trustee shall be required to hold the Trust assets and income for the benefit of the Company’s general creditors in the event of the Company’s insolvency or inability to pay its debts when they mature, and in such case no Participant or Beneficiary shall have a preferred claim on the Trust assets. The Board and the chief executive officer of the Company shall have the duty to inform the trustee in writing of the Company’s insolvency or its inability to pay its debts as they mature within seven (7) days of such event. When so informed, the trustee of the Trust shall suspend payments to all Participants and Beneficiaries and shall hold Trust assets for the benefit of the Company’s general creditors. In the case of the trustee’s actual knowledge of the Company’s insolvency or inability to pay its debts as they mature, the trustee will deliver Trust assets to satisfy claims of the Company’s general creditors as directed by a court of competent jurisdiction. Except as otherwise provided herein, all assets of the Trust, including investment income, shall be retained for the exclusive benefit of Participants and Beneficiaries and shall be used to pay benefits to such persons and to pay administrative expenses and taxes of the Trust to the extent not paid by the Company. At no time prior to the satisfaction of all liabilities under the Plan with respect to Participants and their Beneficiaries shall any of the Trust assets revert to or accrue to the benefit of the Company, except that contributions made by the Company by a mistake of fact may be returned to the Company within one year of the payment date.

11.3Successors and Assigns. A Participant shall not have any right to transfer, assign, encumber, hypothecate or otherwise dispose of his (or his Beneficiary’s) right to receive benefit payments under the Plan. The provisions of the Plan shall bind and inure to the benefit of the Company and its successors and assigns. The term “successors” as used herein shall include any corporation or other business entity which shall, whether by merger, consolidation, purchase or otherwise, acquire all or substantially all of the business or assets of the Company.

11.4Employment Rights. Any payment under this Plan shall be independent of, and in addition to, payments made under any other agreements or under any qualified or nonqualified retirement plan which may be in force between the Company and any Participant or Beneficiary, or any other compensation payable to Participant or his or her Beneficiary by the Company. Neither this Plan nor any form executed in connection herewith shall be construed as (i) constituting or creating a contract of employment, (ii) restricting either the Company’s rights to discharge Participant with or without cause or Participant’s right to terminate his or her employment, or (iii) creating any guarantee or representation as to the amount of compensation to be paid to Participant by the Company during any period of regular employment.

11.5Lost Participants or Beneficiaries. Any Participant or Beneficiary who is entitled to a benefit from the Plan has the duty to keep the Administrator advised of his or her current mailing address. If benefit payments are returned to the Plan or are not presented for payment after a reasonable amount of time, the Administrator shall presume that the payee is missing. The Administrator, after making such efforts as in its discretion it deems reasonable and appropriate to locate the payee, shall stop payment on any uncashed checks and may discontinue making future payments until contact with the payee is restored.

11.6Absence of Liability. Any and all liability created to administer this Plan or to provide any Participant or Beneficiary with benefits under this Plan shall be exclusively and solely that of the Company. Neither the Company, the Administrator, nor any other person, officer or employee, nor any agent of the foregoing, shall be jointly or severally liable for any act or failure to act under the Plan or for anything whatever in connection with the Plan, or the administration thereof, except and only to the extent of liability resulting from gross negligence or fraud. Neither the Administrator, nor any officer, director or employee, past, present or future, of the Company, shall have any liability to any Participant or Beneficiary, or to any other person or entity, to provide or pay such benefits, such liability hereby being expressly and unconditionally denied.

11.7Notices. Any notice or filing required or permitted to be delivered to the Administrator under this Plan shall be delivered in writing, in person, or through such electronic means as is established by the Administrator. Notice shall be deemed given as of the date of delivery or, if delivery is made by mail, as of the date shown on the postmark on the receipt for registration or certification. Written transmission shall be sent by certified mail to the following address with a copy to the Executive Vice President & General Counsel at the same address:

Any notice or filing required or permitted to be given to a Participant under this Plan shall be sufficient if in writing or hand-delivered, or sent by mail to the last known address of the Participant.

11.8Terms. Whenever any words are used herein in the masculine they shall be construed as though they were used in the feminine in all cases where they would so apply and wherever any words are used herein in the singular or in the plural, they shall be construed as though they were used in the plural or the singular, as the case may be, in all cases where they would so apply. Titles of Articles and Sections hereof are for general information only, and the Plan is not to be construed by reference thereto.

11.9Severability. In the event any provision of the Plan shall be held illegal or invalid for any reason, this illegality or invalidity shall not affect the remaining provisions of the Plan, and such remaining provisions shall be fully severable and the Plan shall, to the extent

practicable, be construed and enforced as if the illegal or invalid provision had never been inserted therein.

11.10Governing Law. The provisions of the Plan shall be governed by and construed in accordance with the laws of the State of Washington, except where preempted by ERISA or any other federal statute. Invalidation of any one of the provisions of the Plan for any reason shall in no way affect the other provisions hereof, and all such other provisions shall remain in full force and effect. Venue of any dispute under this Plan shall be in a court of competent jurisdiction in King County, Washington.

11.11Section 409A Compliance. This Plan is intended to comply with Code Section 409A or an exemption thereunder and shall be construed and administered in accordance with Code Section 409A. Notwithstanding any other provision of this Plan, payments provided under this Plan may only be made upon an event and in a manner that complies with Code Section 409A or an applicable exemption. Except as otherwise specifically provided herein, for purposes of Code Section 409A, each installment payment provided under this Plan shall be treated as a separate payment. Any payments to be made under this Plan upon a termination of employment shall only be made if such termination of employment constitutes a “separation from service” under Code Section 409A.

Notwithstanding any other provision of the Plan, if at the time of the Participant’s termination of employment, he is a “specified employee”, determined in accordance with Section 409A, any payments and benefits provided under this Plan that constitute “nonqualified deferred compensation” subject to Section 409A that are provided to the Participant on account of his separation from service shall not be paid until after the six-month anniversary of the Participant’s termination date (“Specified Employee Payment Date”). Any payment that would otherwise have been made during the six-month period shall be paid on the Specified Employee Payment Date and thereafter any remaining annual installments shall be paid on the applicable anniversary of the Specified Employee Payment Date. If the Participant dies during the six-month period, any delayed payment shall be paid to the Participant’s Beneficiary in a lump sum upon the Participant’s death.

IN WITNESS WHEREOF, the Company has executed this amended and restated Plan on this 13th day of June, 2024.
