PHANTOM EQUITY INVESTMENT AGREEMENT

This Phantom Equity Investment Agreement (this “Agreement”) is made as of June 1, 2012, by and among (a) Frontier Airlines, Inc., a Colorado corporation (the “Company”), (b) Republic Airways Holdings Inc., a Delaware corporation (“Republic”), and (c) FAPAInvest, LLC, a Colorado limited liability company (“FAPAInvest”), acting as agent for and on behalf of those persons employed as of June 24, 2011 (the “Agreement Date”) as pilots by the Company (such persons, collectively, the “Participating Pilots”).

WHEREAS, as of the Agreement Date, the Participating Pilots were represented by Frontier Airline Pilots Association (“FAPA”) as parties to that certain Collective Bargaining Agreement with the Company dated as of March 2, 2007 (such agreement, as amended through the Agreement Date, the “CBA”);

WHEREAS, Republic has undertaken a restructuring effort, as presented to the Republic Board of Directors at its May 25, 2011 meeting;

WHEREAS, on the Agreement Date, FAPA and the Company entered into Letter of Agreement 67 to the CBA (such Letter of Agreement 67 dated, and as executed on, the Agreement Date and without regard to any subsequent amendments or modifications, “LOA 67”), pursuant to which FAPA agreed, on behalf of the Participating Pilots, to certain modifications to the CBA (as set forth in Paragraph A of LOA 67) evidencing a deferral of certain payments and employee benefits to which the Participating Pilots would otherwise be entitled under the CBA, in consideration of, among other things, treating such deferrals as investments by the Participating Pilots in the Company (the “Investments”), which gave immediate value to the Company and Republic in executing Republic’s restructuring effort as presented to the Republic Board of Directors at its May 25, 2011 meeting;

WHEREAS, on the Agreement Date, the Company, Republic and FAPAInvest entered into that certain Commercial Agreement (the “Commercial Agreement”), which specifies, among other things, the terms and conditions of the Participating Pilots’ equity participation in the Company, in recognition of the immediate value of the Investments to the Company and Republic as described above;

WHEREAS, Republic owns all of the issued and outstanding equity securities of the Company through its ownership of 100% of Frontier Airlines Holdings, Inc. (“Holdings”); and

WHEREAS, the Company, Republic and FAPAInvest have agreed that the Participating Pilots’ equity participation in the Company in return for the Investments will be accomplished by granting FAPAInvest, for the benefit of the Participating Pilots, phantom equity representing the Participating Pilots’ right to receive from the Company an amount of cash and/or registered shares of the Company’s common stock, no par value (the “Shares”), equal to the value of the equity participation contemplated under the Commercial Agreement, as more particularly set forth herein.

NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, mutual covenants and agreements set forth herein, the parties hereto agree as follows

(capitalized terms contained in this Agreement and not otherwise defined herein shall have the respective meanings ascribed to them in the Commercial Agreement or LOA 67, as applicable):

SECTION 1.PHANTOM EQUITY PARTICIPATION

1.1 Issuance and Vesting of Phantom Units. The parties agree and acknowledge that the aggregate value of the Investments to be made by the Participating Pilots as set forth in Paragraph A of LOA 67 is $39.3 million (the “Investment Value”). Subject to the Company’s and Republic’s satisfaction of the conditions set forth in Paragraph C of the Commercial Agreement (collectively, the “Conditions”) and continued compliance with such Conditions throughout the term of this Agreement, in consideration of the Investments made by the Participating Pilots pursuant to Paragraph A of LOA 67, the Company hereby grants to FAPAInvest, for the benefit of the Participating Pilots, units (“Units”) on the terms and conditions set forth below:

(a) The Units represent a right to receive from the Company cash and/or registered Shares of the Company in the aggregate amount (such amount, the “Net Value”) of up to the Investment Value multiplied by a fraction, the numerator of which is the greater of (i) a price per Share of $0.18, resulting in a Net Value of up to $7.074 million, or (ii) any price per Share that is greater than $0.18 that the Company offers to any other stakeholder in the restructuring of the Company (“Stakeholder”), and the denominator of which is $1.00. For the avoidance of doubt, such Stakeholders shall include, but not be limited to, any other represented or non-represented unions or other employee groups, Embraer, Airbus, GECAS and ▇▇▇▇▇ & ▇▇▇▇▇▇▇. The Company shall promptly provide FAPAInvest with notice of any offers to Stakeholders of Shares or other equity or related consideration in the Company at a price greater than $0.18 per Share. The price per Share as determined under Section 1.1(a)(i) or (ii) shall be the “Per Share Price” hereunder.

(b) The Units shall vest at such times as the Investments are actually made by the Participating Pilots from and after the Agreement Date, as set forth in Paragraph A of LOA 67 and the schedule attached thereto and attached hereto as Schedule 1.1(b). So long as Investments are being made by the Participating Pilots under LOA 67, then within 20 days of the end of each calendar quarter during such period beginning with the quarter ended June 30, 2012, the Company shall prepare and deliver to FAPAInvest a written summary (in a form reasonably acceptable to FAPAInvest) of the Investments made by the Participating Pilots during such calendar quarter, setting forth the Units and the corresponding Investment Value and Net Value that vested during such calendar quarter as a result of the Investments made during such quarter. The parties acknowledge that the Investment Value and Net Value that have vested as of March 31, 2012 are $8,000,000 and $1,440,000, respectively.

(c) With respect to each Participating Pilot, in the event that such Participating Pilot’s employment with the Company ends for any reason, including, without limitation, because of such Participating Pilot’s resignation, retirement, death, or termination of employment by the Company (any such termination of employment, a “Termination Event”), then the vesting of the Participating Pilot’s Pro Rata Share (as defined below) of the Units shall immediately cease as of the effective date of such Termination Event, and the Participating Pilot’s Pro Rata Share of the vested Units shall convert into a corresponding Net Value on one or more Payment Dates as set forth in Section 1.3 below.

1.2 Determination of Pro Rata Share and Allocation Schedule.

(a) Each Participating Pilot’s pro rata share of the vested Units (“Pro Rata Share”) that shall be paid to such Participating Pilot hereunder on a Payment Date (as hereinafter defined) shall be calculated, as of such applicable Payment Date, as (i) the aggregate Net Value that has vested as of such Payment Date (not previously paid out hereunder) and that is to be paid out to the Participating Pilots in accordance with Section 1.3 on such Payment Date, multiplied by (ii) a percentage determined by dividing (A) the taxable compensation of the Participating Pilot from the Company and its Affiliates for the time period beginning on the date the Participating Pilots began to make Investments hereunder and ending on such applicable Payment Date (if the applicable Payment Date is the first Payment Date hereunder) or beginning on the day after the last Payment Date hereunder and ending on such applicable Payment Date (if the applicable Payment Date is a Payment Date other than the first Payment Date hereunder) (such time period, the “Applicable Time Period”), as such compensation is reported in Box 1 of Form W-2 by (B) the aggregate taxable compensation of all Participating Pilots as such compensation is reported for the Applicable Time Period. (For example: if the aggregate Net Value that has vested for all Participating Pilots as of a Payment Date is $1,000,000, a Participating Pilot’s compensation for the Applicable Time Period is $100,000 and the total Participating Pilots’ compensation for the Applicable Time Period is $60,000,000, that Participating Pilot’s Pro Rata Share as of the applicable Payment Date would be $1,667.) Compensation shall not include compensation received by a Participating Pilot from the Company or its Affiliates for services rendered as a Management Pilot.

(b) No later than 10 days prior to each Payment Date, the Company shall deliver to FAPAInvest accurate and complete information (collectively, “Information”) setting forth (i) the effective date(s) of every Termination Event that occurred after the date Participating Pilots first began making Investments hereunder (or after the last Payment Date, as applicable) and prior to such applicable Payment Date, and the name of each Participating Pilot whose employment with the Company was terminated by such Termination Event; (ii) the compensation earned by each Participating Pilot for the Applicable Time Period as described in Section 1.2(a) above; and (iii) the Net Value attributable to the Investments made by all of the Participating Pilots through the applicable Payment Date and not previously paid out hereunder. Based on the Information received, FAPAInvest shall then determine each Participating Pilot’s Pro Rata Share due on such Payment Date and no later than two business days prior to such Payment Date, FAPAInvest shall provide the Company with an allocation schedule (the “Allocation Schedule”) for such Payment Date, which Allocation Schedule shall identify (1) the Participating Pilots who shall receive a cash payment or Shares, as applicable, on such Payment Date and (2) the Pro Rata Share of the Net Value that each such Participating Pilot shall receive on such Payment Date. The Allocation Schedule once provided by FAPAInvest to the Company shall be considered final with respect to the applicable Payment Date, and the Company shall be entitled to rely upon such Allocation Schedule in allocating the Net Value among the Participating Pilots on such Payment Date absent manifest error. For purposes of preparing the Information, determining a Participating Pilot’s Investment and Pro Rata Share, and preparing the Allocation Schedule, any Participating Pilot who has not had a Termination Event prior to the date on which the Information is prepared by the Company shall be deemed to have continued as an employee of the Company through the Payment Date.

(c) FAPAInvest in its sole discretion shall determine any amounts that are to be set aside out of the funds that would have otherwise been distributed to the Participating Pilots under this Agreement to cover costs of the establishment, administration, oversight of, and the enforcement of FAPAInvest’s and the Participating Pilots’ rights under, this Agreement and/or the Frontier Airline Pilots Profit Sharing Plan set up for the benefit of the Participating Pilots. Any payments received by the Participating Pilots under this Agreement will be net of any such amount set aside with FAPAInvest pursuant to this Section. In this regard, FAPAInvest may engage such professionals and service providers as it deems appropriate to assist with the establishment, administration, oversight and enforcement of this Agreement, and include the fees for such persons as costs of establishment, administration, oversight and enforcement of this Agreement for purposes of the set aside under this Section. Any set aside amounts remaining after the last payment to the Participating Pilots under this Agreement shall be allocated and paid to the same Participating Pilots and in the same proportion as such last payment under this Agreement.

1.3 Payments of Net Value

(a) Payments of vested Net Value shall be made on January 1, 2015 or within ninety (90) days thereafter (the “2015 Payment Date”) and/or January 1, 2017 or within ninety (90) days thereafter (the “2017 Payment Date”), subject to acceleration upon the occurrence of certain events that qualify as a change in ownership or effective control, or ownership of a substantial portion of assets, under Treas. Reg. section 1.409A-3(i)(5) of the Internal Revenue Code of 1986, as amended (the “Code”). Any such events that so qualify are referred to as “409A Events” and any events that do not so quality are referred to as “Non-409A Events.” Illustrative events and calculations are attached to this Agreement as Schedule 1.3. Notwithstanding anything herein to the contrary, the parties agree that if there is a 409A PE Event (as defined in paragraph (b) of Schedule 1.3) prior to December 31, 2014, the Participating Pilots will receive, in accordance with the Allocation Schedule, on the date of the closing of the 409A PE Event, in cash, the lesser of (i) the Net Value attributable to all Units that have vested through such date or (ii) $1,768,000. The parties hereto acknowledge that there may be other events and circumstances not covered by this Section 1.3 or Schedule 1.3 that may occur. The parties agree to address such events in a manner that to the extent practicable is consistent with this Section 1.3 and Schedule 1.3 with the intent of this Agreement to provide Net Value to the Participating Pilots in a manner that complies with Section 409A of the Code. The 2015 Payment Date, the 2017 Payment Date and any other date on which a payment is made to the Participating Pilots hereunder as a result of acceleration of payment upon the occurrence of a 409A Event shall be referred to hereinafter as a “Payment Date” and collectively as the “Payment Dates”.

(b) As used herein, the term “Equity Event” means: (i) an investment in the Company, directly or indirectly, by investors other than affiliates of Republic (“Nonaffiliates”) that, when combined with (x) the equity participation of FAPAInvest in the Company based on the then current Net Value of the Units and (y) equity participation of other Stakeholders, results in beneficial ownership by Nonaffiliates of greater than 51% of the outstanding equity in the Company (“Private Equity Event”); (ii) sale to the public by the Company, Holdings or another subsidiary of Republic of Shares registered with the Securities and Exchange Commission (“SEC”) pursuant to Section 12 of the Securities Exchange Act of 1934, as amended, that, when combined

with (x) the equity participation of FAPAInvest in the Company based on the then current Net Value of the Units and (y) equity participation of other Stakeholders, results in beneficial ownership by Nonaffiliates of greater than 51% of the outstanding equity in the Company (“Public Offering”); or (iii) a merger, sale or other change of control transaction that results in beneficial ownership by Nonaffiliates of greater than 51% of the business or assets of the Company (a “Change in Control Transaction”). Any of the foregoing Equity Events in (i) or (ii) may be 409A Events or Non-409A Events; the Equity Event in (iii) shall be deemed a 409A Event.

1.4 Cessation of Investments. In addition to the immediate cessation of the making of Investments by the Participating Pilots as required by paragraph C.1. of LOA 67, the vesting of Units shall immediately cease if the Company and/or Republic fail to satisfy the Conditions at any time prior to a Payment Date under Section 1.3.

1.5 Reduction in Value of Investment. To the extent any Investment is not made by the Participating Pilots in accordance with Paragraph A of LOA 67 (excluding an individual Participating Pilot’s failure to make an Investment as a result of a Termination Event, and excluding a failure to make an Investment as a result of the Company’s or Republic’s failure to satisfy the Conditions or other breach of this Agreement), the Investment Value shall be reduced by the net present value discount rate of 15% with respect to such Investment which is not made and the Net Value shall be reduced accordingly, in accordance with the schedule attached to the Commercial Agreement and to this Agreement.

(a) No Equity Event by 2014. If no Equity Event occurs on or before December 31, 2014, on the 2015 Payment Date the Company shall pay to the Participating Pilots, in accordance with the Allocation Schedule, in cash the Net Value attributable to all Units that have vested through December 31, 2014.

(b) 409A PE Event by 2014 and No Other Events Thereafter. If one or more Equity Events that are Private Equity Events (as defined in Section 1.3(b)(i)) occurs on or prior to December 31, 2014 that are 409A Events (a “409A PE Event”), and no other events occur prior to December 31, 2016, the Company shall pay to the Participating Pilots, in accordance with the Allocation Schedule, in cash (i) on the date of the closing of the Private Equity Event, the lesser of the Net Value attributable to all Units that have vested through such date or $1,768,000; (ii) on the 2015 Payment Date, an additional amount, if any (but not less than zero), equal to the 2014 Valuation (as such term is defined below) multiplied by the 2015 Payment Percentage (as such term is defined below); and (iii) on the 2017 Payment Date, an additional amount, if any (but not less than zero), equal to the 2016 Valuation (as such term is defined below) multiplied by the 2017 Payment Percentage (as such term is defined below), determined as follows:

(x) (A) The percentage of FAPAInvest’s ownership of the Company as of December 31, 2014 shall be determined by dividing the Net Value attributable to all Units that have vested through December 31, 2014 by the valuation of the Company upon the occurrence of the first Private Equity Event as adjusted to deduct the percentage attributable to the cash paid in (b)(i) above (the “2015 Payment Percentage”). Such valuation shall be the fair market value of the Company based on the total investment (including debt incurred, paid or assumed by the Company or assumed by the investors) of the parties triggering the first Private Equity Event.

(B) The percentage of FAPAInvest’s ownership of the Company as of December 31, 2016 shall be determined by dividing the Net Value attributable to all Units that have vested from January 1, 2015 through December 31, 2016 by the valuation of the Company upon the occurrence of the first Private Equity Event (the “2017 Payment Percentage”). Such valuation shall be the fair market value of the Company based on the total investment (including debt incurred, paid or assumed by the Company or assumed by the investors) of the parties triggering the first Private Equity Event.

(y) A valuation of the Company shall be computed as of December 31, 2014 (the “2014 Valuation”) or as of December 31, 2016 (the “2016 Valuation”). Unless the Company and FAPAInvest agree upon a valuation, such valuation shall be a valuation determined by an accounting firm, valuation firm or other firm providing similar valuation services that is of recognized standing nationally in the United States (each such firm, a “Valuation Firm”) and engaged by the Company and agreed to by FAPAInvest; provided that if the Company and FAPAInvest cannot agree on a Valuation Firm, FAPAInvest shall select and engage a second Valuation Firm. Each Valuation Firm shall deliver its written determination of the Company’s fair market value as of December 31, 2014 or as of December 31, 2016, as the case may be (the “Valuation”) to both

the Company and FAPAInvest within thirty (30) days of being retained. The Valuation of the Company or, if there are two Valuations the average of the two Valuations of the Company, shall be the final 2014 Valuation or 2016 Valuation of the Company and shall be final and binding upon all parties hereto.

(d) 409A IPO by 2014 and No Other Events Thereafter. If an Equity Event that is a Public Offering (as defined in Section 1.3(b)(ii)) occurs prior to December 31, 2014 that is a 409A Event (a “409A IPO”), and no other events occur prior to December 31, 2016, the Company shall issue and deliver to the Participating Pilots, in accordance with the Allocation Schedule, (i) on the date of the closing of the 409A IPO, Shares registered with the SEC equal to the Net Value attributable to all Units that have vested through the date of closing of the 409A IPO, (ii) on the 2015 Payment Date, Shares registered with the SEC equal to the Net Value attributable to all Units that have vested from the date of closing of the 409A IPO through December 31, 2014, and (iii) on the 2017 Payment Date, Shares registered with the SEC equal to the Net Value attributable to all Units that have vested from January 1, 2015 through December 31, 2016.

Notwithstanding the foregoing, if the Shares are not traded on an exchange or over-the-counter market as of a Payment Date or the Company cannot otherwise deliver registered shares at the time of the 409A IPO despite commercially reasonable efforts to do so, the Company shall, in lieu of issuing Shares to the Participating Pilots, pay to the Participating Pilots an amount equal to the fair market value of the Shares as reasonably determined by the Board of Directors of the Company without minority or marketability discounts. The Company shall provide FAPAInvest with a notice of such fair market value promptly upon determination along with reasonable documentation supporting such determination. FAPAInvest shall have ten (10) days to object to such fair market value determination.
