(Complete appropriate section on subsequent pages of this form.)

The Company is conducting a Rights Offering, which entitles holders of the Company’s Series A Liberty SiriusXM Common Stock, par value $0.01 per share (“Series A Liberty SiriusXM Common Stock”), Series B Liberty SiriusXM Common Stock, par value $0.01 per share (“Series B Liberty SiriusXM Common Stock”), and Series C Liberty SiriusXM Common Stock to receive 0.0939 of a Right for each share of Series A Liberty SiriusXM Common Stock, Series B Liberty SiriusXM Common Stock, or Series C Liberty SiriusXM Common Stock held by them as of 5:00 P.M. New York City time, on May 13, 2020 (the “Record Date”). Each whole Right entitles the holder to subscribe for one share of Series C Liberty SiriusXM Common Stock pursuant to its Basic Subscription Privilege and, if its Basic Subscription Privilege is fully exercised, to subscribe for additional shares of Series C Liberty SiriusXM Common Stock pursuant to its Oversubscription Privilege. If the aggregate Subscription Price delivered or transmitted by the Rightsholder with the Rights Certificate exceeds the aggregate Subscription Price for all shares for which the Rightsholder would be entitled to subscribe pursuant to its Basic Subscription Privilege and no direction is given as to the excess, such Rightsholder will be deemed to have subscribed for a number of Excess Shares equal to the maximum whole number of Excess Shares that could be purchased with such excess Subscription Price. Shares of Series C Liberty SiriusXM Common Stock purchased pursuant to the Rights Offering will be issued by the Transfer Agent as soon as practicable following the Expiration Time. No fractional Rights or cash in lieu thereof were issued or paid and fractional Rights were rounded up to the nearest whole Right, as described in the Prospectus. Set forth herein is the number of Rights evidenced by this Rights Certificate that the Rightsholder is entitled to exercise pursuant to such Rightsholder’s Basic Subscription Privilege. If shares of Series A Liberty SiriusXM Common Stock, Series B Liberty SiriusXM Common Stock, or Series C Liberty SiriusXM Common Stock applicable to a subscription are held by more than one record holder, the Rights Certificate must be signed by each such holder; if a holder or joint holders (registrants) hold more than one position in the Company, as indicated by different accounts on the relevant record holder list, then separate, properly completed and executed Rights Certificates must be submitted for each such position held by that or those joint holders (registrants).

This Rights Certificate is transferable, and may be combined or divided (but only into Rights Certificates evidencing full rights) at the office of the Subscription Agent. Rightsholders should be aware that if they choose to exercise, assign, transfer or sell only part of their Rights they may not receive a new Rights Certificate in sufficient time to exercise, assign, transfer or sell the remaining Rights evidenced thereby.
