(2)	Due to the Reporting Person's resignation from the Company and pursuant to the provisions of Spirit Airlines, Inc.'s 2011 Equity Incentive Plan (the "Plan"), all unvested Restricted Stock Units have been cancelled.
(3)	This transaction was executed in multiple trades in prices ranging from $30.89 to $31.06, inclusive. The price reported in Column 4 above reflects the weighted average sale price. The Reporting Person hereby undertakes to provide to the Securities and Exchange Commission staff, the Issuer, or a security holder of the Issuer, upon request, full information regarding the number of shares sold at each respective price within the range set forth in this footnote.
(4)	This transaction was executed in multiple trades in prices ranging from $30.43 to $30.81, inclusive. The price reported in Column 4 above reflects the weighted average sale price.

(5)	50% of the shares that remain subject to the option would vest and become exercisable on each of June 20, 2014 and June 20, 2015, such that 100% of the shares that remain subject to the option would be fully vested and exercisable on June 20, 2015.
