          THIS AMENDED AND RESTATED STOCK OPTION AGREEMENT (this “Agreement”), dated February 14, 2011, between SIRIUS XM RADIO INC., a Delaware corporation (the “Company”), and JAMES E. MEYER (the “Executive”). This Agreement amends and restates the Stock Option Agreement dated October 14, 2009 between the Company and the Executive (the “Original Agreement”).

          1. Grant of Option; Vesting. (a) Subject to the terms and conditions of this Agreement, the Sirius XM Radio 2009 Long-Term Stock Incentive Plan (the “Plan”), and the Employment Agreement, dated as of October 14, 2009, between the Company and the Executive (as amended by the First Amendment, dated as of February 14, 2011, the “Employment Agreement”), the Company has granted to the Executive the right and option (this “Option”) to purchase twenty five million one hundred eighty four thousand nine hundred and eighty four (25,184,984) shares (the “Shares”) of common stock, par value $0.001 per share, of the Company at a price per share of $0.5752 (the “Exercise Price”). This Option is not intended to qualify as an Incentive Stock Option for purposes of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”). In the case of any stock split, stock dividend or like change in the Shares occurring after the date hereof, the number of Shares and the Exercise Price shall be adjusted as set forth in Section 4(b) of the Plan.

          (b) Subject to the terms of this Agreement, this Option shall vest and become exercisable in four equal installments on each of October 14, 2010, October 14, 2011, October 14, 2012 and October 14, 2013.

          (c) If the Executive’s employment with the Company terminates for any reason, including as a result of a Scheduled Retirement (as defined in the Employment Agreement) this Option, to the extent not then vested, shall immediately terminate without consideration; provided that if the Executive’s employment is terminated (i) due to death or Disability (as defined in the Employment Agreement) the portion of this Option that would have otherwise become vested within 12 months following the date of such termination of employment due to death or Disability shall immediately become vested and exercisable; and (ii) by the Company without Cause (as defined in the Employment Agreement), or by the Executive for Good Reason (as defined in the Employment Agreement), the unvested portion of this Option, to the extent not previously cancelled or forfeited, shall immediately become vested and exercisable.

          2. Term. This Option shall terminate on October 14, 2019 (the “Option Expiration Date”); provided that if:

5

          (a) the Executive’s employment with the Company is terminated due to the Executive’s death or Disability, by the Company without Cause, by the Executive for Good Reason or by the Executive as a result of a Scheduled Retirement (as defined in the Employment Agreement), the Executive may exercise this Option in full until the first anniversary of such termination (at which time the Option shall be cancelled), but not later than the Option Expiration Date;

          (b) the Executive’s employment with the Company is terminated for Cause, the Option shall be cancelled upon the date of such termination; and

          (c) the Executive voluntarily terminates his employment with the Company without Good Reason, the Executive may exercise the vested portion of this Option until ninety days following the date of such termination (at which time the Option shall be cancelled), but not later than the Option Expiration Date.

          3. Exercise. Subject to Sections 1 and 2 of this Agreement and the terms of the Plan, this Option may be exercised, in whole or in part, in accordance with Section 6 of the Plan.

          4. Non-transferable. This Option may not be transferred, assigned, pledged or hypothecated in any manner (whether by operation of law or otherwise) other than by will or by the applicable laws of descent and distribution, and shall not be subject to execution, attachment or similar process. Any attempt to transfer, assign, pledge, hypothecate or otherwise dispose of the Option or of any right or privilege conferred hereby shall be null and void.

          5. Withholding. Prior to delivery of the Shares purchased upon exercise of this Option, the Company shall determine the amount of any United States federal, state and local income tax, if any, which is required to be withheld under applicable law and shall, as a condition of exercise of this Option and delivery of certificates representing the Shares purchased upon exercise of this Option, collect from the Executive the amount of any such tax to the extent not previously withheld. The Executive may satisfy his withholding obligations in the manner contemplated by Section 14(d) of the Plan.

          6. Rights of the Executive. Neither this Option, the execution of this Agreement nor the exercise of any portion of this Option shall confer upon the Executive any right to, or guarantee of, continued employment by the Company, or in any way limit the right of the Company to terminate employment of the Executive at any time, subject to the terms of the Employment Agreement or any other written employment or similar agreement between the Company and the Executive.

          7. Professional Advice. The acceptance and exercise of this Option may have consequences under federal and state tax and securities laws that may vary depending upon the individual circumstances of the Executive. Accordingly, the Executive acknowledges that the Executive has been advised to consult his personal legal and tax advisor in connection with this Agreement and this Option.
