Item 5.02 Departure of Directors or Principal Officers; Election of Directors; Appointment of Principal Officers.

On February 9, 2006, Sonic’s Board of Directors appointed David P. Cosper as Sonic’s Executive Vice President and Treasurer, effective March 1, 2006. Mr. Cosper was also appointed as Chief Financial Officer, and will begin performing the functions of principal financial officer, effective on the first business day following the filing of Sonic’s Annual Report on Form 10-K for the year ended December 31, 2005. The material terms of the employment agreement between Sonic and Mr. Cosper are incorporated herein by reference from Sonic’s Form 8-K filed February 7, 2006.

Prior to joining Sonic, Mr. Cosper, 51, was Chief Financial Officer and Vice Chairman of Ford Motor Credit Company since 2003 and 2004, respectively. In those positions, he was responsible for all financial planning, analysis and accounting operations, as well as risk management, audit and public affairs. Prior to assuming those positions, Mr. Cosper had served as Vice President and Treasurer of Ford Motor Credit since 1998. From 1979 when he joined Ford Motor Company, Mr. Cosper served in a variety of positions at Ford Motor Credit and Ford Motor Company, including assistant treasurer of Ford Motor Company and executive director of Corporate Finance at Ford Motor Company. In such positions, Mr. Cosper was responsible for international treasury issues, risk management, trading and treasury operations, systems and accounting, as well as profit analysis, business planning and competitive and strategic analysis.

On February 7, 2006, Thomas P. Capo informed Sonic that he will not seek re-election to Sonic’s Board of Directors. Mr. Capo will serve out his term as a director through the 2006 annual stockholders’ meeting.

Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

Sonic’s Board of Directors approved amendments to Sonic’s bylaws effective February 9, 2006 to phase out the present three-year staggered terms of directors. The new procedures in Section 3.02 of the bylaws will apply to all directors elected at the 2006 annual stockholders’ meeting, including any current directors who are re-nominated after their current terms expire. At each annual election of directors by the stockholders beginning in 2006, the directors chosen to succeed those whose terms are then expired will be elected by the stockholders for a one-year term. Section 3.04 of the bylaws was amended to reflect the annual election of directors and to

A copy of the amended and restated bylaws is filed herewith as Exhibit 3.1 and is incorporated by reference. The foregoing description of the amended and restated bylaws does not purport to be complete and is qualified in its entirety by reference to such exhibit.
