Dear Mr. Lefebvre:

On behalf of Spirit Airlines, Inc., I would like to take this opportunity to welcome you and confirm the terms of our offer of employment. We believe that such an association would be mutually beneficial, and we are enthusiastic about having you join Spirit.

Your title will be Senior Vice President, Customer Service and you will report to, Ben Baldanza, President & Chief Operating Officer. Your annual base salary will be $200,000.00 and you will commence employment no later than October 31, 2005, but ideally sooner, if practical. Spirit will also provide you with a monthly car allowance of $500.00. You will be eligible for the Profit Sharing Plan per Company policy which will be equivalent to other SVPs at Spirit.

The Company is in the final stage of finalizing an equity-sharing plan for executives and you will be provided an entitlement equivalent to 0.50% of the Company’s common stock under the same terms and conditions as offered to the SVPs.

On your start date you will be eligible for Company-paid employee benefits, which include medical, life and dental insurance, and participation in Section 125 Flexible Benefits Plan. At that time, you and your family will be eligible for unlimited positive space airline travel privileges on Spirit and will be entitled to Spirit Plus, per the Travel Policy. You will also receive travel privileges on other specified airlines per their respective agreements.

After one year of employment, you will be eligible to participate in Spirit’s 40lK Plan, according to the 401K Plan guidelines. Additionally, you will be provided Company-paid Long-Term Disability Insurance. You will be eligible to take three week’s vacation during your first year of employment, which will be charged against your first year accrual.

We recognize that as part of this opportunity, you may wish to sell your home in Virginia and purchase a home in South Florida. In an effort to assist you with relocation, Spirit will provide you with up to $60,000.00 of relocation funds which may also be used for closing costs (excluding down payment or deposit) of housing transactions, $10,000 which will not require receipts. This relocation package is available for up to one (1) year from your date of hire. The intent of this provision is neither for you to make or lose money on this move.
