On December 9, 2011, Fiesta Restaurant Group, Inc. (“Fiesta Restaurant Group”), a wholly-owned subsidiary of Carrols Restaurant Group, Inc. (“Carrols Restaurant Group”), filed a Registration Statement on Form 10 (the “Registration Statement”) with respect to the previously announced spin-off of Fiesta Restaurant Group by Carrols Restaurant Group. The following information relating to the spin-off was included in the preliminary information statement (subject to completion) filed as Exhibit 99.1 to the Registration Statement.

It is anticipated that under the transition services agreement to be entered into in connection with the spin-off by Fiesta Restaurant Group, Carrols Restaurant Group and Carrols Corporation (“Carrols”), a wholly-owned subsidiary of Carrols Restaurant Group, Carrols Restaurant Group and Carrols will agree to provide certain support services (including accounting, tax accounting, treasury management, internal audit, financial reporting and analysis, human resources, and employee benefits management, information systems, restaurant systems support, legal, lease and franchise administration and risk management services) to Fiesta Restaurant Group to help ensure an orderly transition following the spin-off by providing Fiesta Restaurant Group with sufficient time to develop its own infrastructure. Fiesta Restaurant Group will also agree to provide certain limited management services (including certain legal services) to Carrols Restaurant Group and Carrols.

It is anticipated that the transition services agreement will establish a baseline charge for each category or component of services to be provided and/or will pro-rate the overall cost of such category or categories of services between Fiesta Restaurant Group and Carrols Restaurant Group and its subsidiaries. It is anticipated that the price to be charged for each service will be based on the allocated cost of providing such service. The transition services agreement will also provide for adjustments to the charge for such services based upon such factors as increases in the number of restaurants, addition and/or subtraction of services and incremental charges for special projects or significant transactions including the transition of such functions to Fiesta Restaurant Group. The charge for the services will also be subject to adjustment based upon increases in the consumer price index.

The transition services agreement will be effective upon the completion of the spin-off and it is anticipated that it will continue for a minimum term of three years; provided that Fiesta Restaurant Group may extend the term of the transition services agreement by one additional year upon three months prior written to Carrols Restaurant Group and Carrols; and provided further that Fiesta Restaurant Group may terminate the transition services agreement with respect to any service provided thereunder at any time and from time to time upon 90 days prior written notice to Carrols Restaurant Group and Carrols.

In connection with the spin-off, it is anticipated that Joseph A. Zirkman, currently the Vice President, General Counsel and Secretary of Carrols Restaurant Group and Fiesta Restaurant Group will remain as the Vice President, General Counsel and Secretary of Fiesta Restaurant Group and, effective as of the date of the completion of the spin-off, will resign all of his positions at Carrols Restaurant Group. Paul R. Flanders, currently the Vice President, Chief Financial Officer and Treasurer of Carrols Restaurant Group and Fiesta Restaurant Group, and

Mr. Flanders will serve as Fiesta Restaurant Group’s interim Chief Financial Officer effective as of the date of the completion of the spin-off until such time as Fiesta Restaurant Group hires a permanent Chief Financial Officer. Mr. Flanders and Mr. LaLonde will remain executive officers of Carrols Restaurant Group following the date of the completion of the spin-off. In addition, in connection with the spin-off, Michael A.
