MOLSON COORS BEVERAGE CO

23.1 Awards Subject to Section 409A. The provisions of this Article 23 shall apply to any Award or portion thereof that is or becomes deferred compensation subject to Code Section 409A (a “409A Award”), notwithstanding any provision to the contrary contained in the Plan or the Award Agreement applicable to such Award. The Plan and Awards granted under the Plan are intended to be exempt from or comply with the requirements of Code Section 409A and the Plan and Awards shall be interpreted accordingly. The preceding provision, however, shall not be construed as a guarantee by the Company of any particular tax effect to any Participant under the Plan. The Company shall not be liable to any Participant for any Award that is determined to result in an additional tax, penalty, or interest under Code Section 409A, nor for reporting in good faith any payment made under the Plan as an amount includible in gross income under Code Section 409A. Nothing in the Plan or any Award shall require the Company to provide any Participant with any gross-up for any tax, interest or penalty incurred by the Participant under Code Section 409A.

23.2 Deferral and/or Distribution Elections. Except as otherwise permitted or required by Code Section 409A, the following rules shall apply to any deferral and/or elections as to the form of distribution (each, an “Election”) that may be permitted or required by the Committee pursuant to a 409A Award:

(a) Any Election must be in writing and specify the amount being deferred, and the time and form of distribution as permitted by the Plan.

(b) Any Election shall become irrevocable as of the deadline specified by the Committee, which shall not be later than December 31 of the year preceding the year in which services relating to the Award commence; provided, however, that if the Award qualifies as “performance-based compensation” for purposes of Code Section 409A and is based on services performed over a period of at least twelve (12) months, then the deadline may be no later than six (6) months prior to the end of such performance period.

(c) Unless otherwise provided by the Committee, an Election shall continue in effect until a written election to revoke or change such Election is received by the Committee, prior to the last day for making an Election for the subsequent year.

23.3 Subsequent Elections. Except as otherwise permitted or required by Code Section 409A, any 409A Award which permits a subsequent Election to further defer the distribution or change the form of distribution shall comply with the following requirements:

(a) No subsequent Election may take effect until at least twelve (12) months after the date on which the subsequent Election is made;

(b) Each subsequent Election related to a distribution upon separation from service, a specified time, or a change in control as defined in Section 23.4(e) must result in a delay of the distribution for a period of not less than five (5) years from the date such distribution would otherwise have been made; and

(c) No subsequent Election related to a distribution to be made at a specified time or pursuant to a fixed schedule shall be made less than twelve (12) months prior to the date the first scheduled payment would otherwise be made.

23.4 Distributions Pursuant to Deferral Elections. Except as otherwise permitted or required by Code Section 409A, no distribution in settlement of a 409A Award may commence earlier than:

(a) Separation from service (as defined in Section 18.3 of the Plan);

(b) The date the Participant becomes Disabled (as defined below);

(c) The Participant’s death;

(d) A specified time (or pursuant to a fixed schedule) that is either (i) specified by the Committee upon the grant of the Award and set forth in the Award Agreement or (ii) specified by the Participant in an Election complying with the requirements of Section 23.2 and/or 23.3, as applicable; or

(e) A change in control within the meaning of Treasury Regulation Section 1.409A-3(i)(5). For avoidance of doubt, this is not the same as the term defined in Section 2.9.

23.5 Six Month Delay. Notwithstanding anything herein to the contrary, to the extent that distribution of a 409A Award is triggered by a Participant’s separation from service, if the Participant is then a “specified employee” (as defined in Code Section 409A), no distribution may be made before the date which is six (6) months after such Participant’s separation from service, or, if earlier, the date of the Participant’s death.

23.6 Disabled. If a 409A Award provides for distribution upon the Participant’s becoming Disabled, “disabled” shall mean:

(a) the Participant is unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or can be expected to last for a continuous period of not less than twelve (12) months, or

(b) the Participant is, by reason of any medically determinable physical or mental impairment which can be expected to result in death or can be expected to last for a continuous period of not less than twelve (12) months, receiving income replacement benefits for a period of not less than three (3) months under an accident and health plan covering employees of the Participant’s employer.

Unless the Award Agreement otherwise provides, all distributions payable by reason of a Participant becoming disabled shall be distributed as provided in the Participant’s Election. If the Participant has made no Election with respect to distributions upon becoming Disabled, all such distributions shall be paid in a lump sum within 90 days following the date the Participant becomes Disabled.

23.7 Death. Unless the Award Agreement otherwise provides, if a Participant dies before complete distribution of amounts payable upon settlement of a 409A Award, such undistributed amounts, to the extent vested, shall be distributed as provided in the Participants Election. If the Participant has made no Election with respect to distributions upon death, all such distributions shall be paid in a lump sum within 90 days following the date of the Participant’s death.

23.8 No Acceleration of Distributions. The Plan does not permit the acceleration of the time or schedule of any distribution under a 409A Award, except as provided by Code Section 409A and/or the Secretary of the U.S. Treasury.
