STOCK UNIT AGREEMENT

THIS STOCK UNIT AGREEMENTis made as of the            day
of            , 200    (the "Grant
Date"), between Frontier Airlines, Inc., a Colorado corporation (together with any affiliate, the "Company"),
and                        (the "Grantee").

1.Definitions.The following terms, when used in this
Agreement, shall have the following meanings:



2.Grant of Units.Pursuant to the Plan and subject to the terms
and conditions of this Agreement, the Company hereby grants to the Grantee            stock units ("Units") effective as of the Grant Date. Each Unit represents the right to receive one
share of
Stock at the time provided in this Agreement.

3.Vesting.



4.Payment for Units, Delivery of Stock Certificates.When the
Units become payable, they shall be settled in shares of Stock. The Units shall become payable on the thirtieth (30th) day following the earlier of (i) the fifth
(5th) anniversary of the Grant Date or (ii) the date the Grantee terminates employment for any reason with vested Units (the "Payment Date"), unless provided otherwise in this
Agreement. Subject to the provisions of Section 7 below, Stock certificates evidencing the Stock, or an electronic transfer of shares to the Grantee's broker (in either case, the
"Certificates"), shall be issued to the Grantee as of the Payment Date and registered in the Grantee's name on the records of the Company. Subject to and conditioned on the satisfaction of any
withholding obligations, the Certificates shall be delivered to the Grantee as soon as practicable after the Payment Date. Notwithstanding the foregoing, if, at the time that payment is due under this
Section 4, the Company's deduction for compensation payable to the Grantee is subject to the restrictions of Section 162(m) of the Code ("Section 162(m)"), payment shall not be
made until the Company's deduction for the compensation attributable to the payment is not limited by Section 162(m). Further, if the Grantee is a "key employee" for purposes of
Section 409A of the Code, payment shall be delayed for 6 months or other period required by Section 409A of the Code.

5.Dividend Equivalents.If the Company pays a cash dividend or
makes any other cash distribution with respect to the Stock during the vesting period, the Grantee shall be granted a number of additional Units (referred to as dividend equivalents) equal to the
amount of cash distributed with respect the
number of shares of Stock that is equal to the number of Units set forth in Section 2 divided by the Fair Market Value of a share of Stock on the date the cash dividend or distribution is made
to the shareholders. The Units representing dividend equivalents shall vest (or shall be forfeited) and, to the extent vested, shall be paid, at the same time as the Units granted under
Section 2.

6.Adjustment of and Changes in the Common Stock.The Units
shall be adjusted as provided in Section 11 of the Plan; provided that no adjustment shall be contrary to Code section 409A or shall be effected in a manner that would subject the
Grantee to taxes and penalties under Code section 409A.

7.Withholding.Upon the award, vesting, and/or payment of any
number of the Units, the Grantee shall make appropriate arrangements with the Company to make payment to the Company of the amount required to be withheld under applicable federal, state, local, and
other tax laws (collectively, "Withholding Taxes"). The Grantee may elect to pay such Withholding Taxes in cash by delivering to the Company a check payable to the order of the Company or, if the
Company agrees, by authorizing the Company to withhold the amount due from the Grantee's pay during the pay periods immediately preceding and following the date on which any such Withholding Tax
liability arises. If the Withholding Taxes arise on or after the date the Units become payable, the Grantee may, in addition to the methods described in the preceding sentence, elect to pay such
Withholding Taxes (a) by selling a portion of the Stock then payable under this Agreement if otherwise permitted by this Agreement or (b) as permitted by Section 14 of the Plan
and as otherwise permitted by this Agreement, by having the Company withhold from the shares otherwise payable and deliverable to the Grantee a number of shares having a Fair Market Value equal to the
amount of the minimum required Withholding Taxes, or such lesser amount as the Grantee may elect. In such case, the value of the shares to be withheld shall


be based on the Fair Market Value of the shares on the date the amount of Withholding Taxes is determined (the "Tax Date"). The Grantee must make an irrevocable election of the manner of payment of
the Withholding Taxes no later than fourteen (14) calendar days prior to the Tax Date; provided however, if the Grantee is subject to Section 16(b) of the Securities
Exchange Act of 1934, the election shall be made in accordance with the requirements of Rule 16b-3. If, on and after the time the Units become payable, the Grantee has not made
arrangements satisfactory to the Company to pay the Withholding Taxes, the Company shall withhold from the shares, a number of shares having a Fair Market Value equal to the amount required to pay the
Withholding Taxes. The value of the shares to be withheld shall be based on the Fair Market Value of the shares on the Tax Date. The Company shall not deliver any shares of Stock unless and until the
Grantee has delivered to the Company, or has made arrangements satisfactory to the Company to provide fully for the payment of, the required Withholding Taxes.

8.Restriction on Transferability; Nonalienability of Benefits.



9.No Rights as a Shareholder.The Grantee shall have no voting
or any other rights as a stockholder of the Company with respect to the Units. Upon payment of the Units and the transfer of shares of Stock to the Grantee, the Grantee shall have all of the rights of
a shareholder of the Company. The Grantee's right to receive Stock under this Agreement shall be no greater than the right of any unsecured general creditor of the Company.

10.Stock Reserve.The Company shall at all times during the
term of this Agreement reserve and keep available such number of shares of Stock as will be sufficient to satisfy the requirements of this Agreement, and the Company shall pay all original issue taxes
(if any) on the issue of Stock pursuant to this Agreement, and all other fees and expenses necessarily incurred by the Company in connection therewith.

11.Miscellaneous.



Any
such notice shall be deemed to have been given as of the second day after deposit in the United States mails, postage prepaid, properly addressed as set forth above, in the case of
mailed notice, or as of the date delivered in the case of personal delivery.



IN WITNESS WHEREOF, the parties have executed this Agreement as of the day and year first above written.
