*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	Includes 31,800 Restricted Stock Units.
(2)	On May 17, 2013, the Reporting Person transferred 27,489 shares of Common Stock to Meabs Bay LP, a limited partnership in which the Reporting Person holds a controlling interest. The total amount of securities beneficially owned as reported herein reflects such transfer.
(3)	The Reporting Person transferred 2,500 shares of Common Stock to Meabs Bay LP, a limited partnership in which the Reporting Person holds a controlling interest, immediately following the option exercise reported herein.
(4)	Please note the Form 4 filed by the Reporting Person on May 7, 2013 inadvertently over reported the number of shares withheld by 177 shares. Therefore, the total amount of securities beneficially owned as reported herein reflects an adjustment of 177 shares.
(5)	Shares held by Meabs Bay LP, a limited partnership in which the Reporting Person holds a controlling interest.
(6)	25% of the shares that remain subject to the option would vest and become exercisable on February 2, 2014. However, in accordance with Spirit Airlines, Inc.'s 2011 Equity Incentive Award Plan (the "Plan"), the remaining unvested shares subject to the option will not be exercisable as a result of the Reporting Person's resignation from the Company.
(7)	Due to the Reporting Person's resignation from the Company and the provisions of the Plan, the unvested portion of this option has been cancelled.
