AIRLINE
      SERVICES, SCHEDULES AND FARES




*Section
      2.01*  *Capacity
      Purchase.* Frontier
      agrees to purchase the capacity of each Covered Aircraft for the period
      beginning on the date such aircraft is presented for service by RAI under this
      Agreement and ending on the last day of the Term, or as such date may be
      extended pursuant to Section
      10.17 hereof,
      in each case unless such aircraft is earlier withdrawn pursuant to Article
      VIII ,
      all
      under the terms and conditions set forth herein and for the consideration
      described in Article III .
      Subject
      to the terms and conditions of this Agreement, RAI shall provide all of the
      capacity of the Covered Aircraft solely to Frontier and use the Covered Aircraft
      solely to operate the Scheduled Flights. Except as provided in Section
      2.01(e) ,
      the
      Covered Aircraft may not be used by RAI for any other purpose without the
      express prior written consent of Frontier.




*(a)*  *Fares,
      Rules and Seat Inventory* .
      Frontier shall establish and publish all fares and related tariff rules for
      all
      seats on the Covered Aircraft. RAI shall not publish any fares, tariffs, or
      related information for the Covered Aircraft. In addition, Frontier shall have
      complete control over all seat inventory and inventory and revenue management
      decisions for the Covered Aircraft, including overbooking levels, discount
      seat
      levels and allocation of seats among various fare buckets.




*(b)*  *Flight
      Schedules* .
      Frontier shall, in its sole discretion, establish and publish all schedules
      for
      the Covered Aircraft (such scheduled flights, together with Charter Flights
      and
      ferry flights required to accommodate such scheduled flights and Charter Flights
      or otherwise made at Frontier's request, referred to herein as “ Scheduled
      Flights ”),
      including determining the city-pairs served, frequencies, utilization and timing
      of scheduled arrivals and departures, and shall, in its sole discretion, make
      all determinations regarding the establishment and scheduling of any Charter
      Flights; *provided* that
      such schedules shall be subject to Reasonable Operating Constraints. Frontier
      shall also be entitled, in its sole discretion and at any time prior to takeoff,
      to direct RAI to delay or cancel a Scheduled Flight, including without
      limitation for delays and cancellations that are air traffic control or weather
      related, and RAI shall take all necessary action to give effect to any such
      direction, provided, however, that such delays or cancellations will not violate
      the minimum scheduling parameters of Exhibit
      G .
      Subject
      to the notice requirement set forth in Section 4.08 regarding international
      service, Frontier will provide RAI with a preliminary schedule in a Standard
      Schedule Input Message (“ SSIM ”)
      file
      format 45 days prior to the first day of the month to which the preliminary
      schedule relates. RAI will review the proposed schedule and provide feedback
      to
      Frontier no later than seven days following receipt of the preliminary schedule
      by RAI. Frontier will send RAI a Final Monthly Schedule, together with
      operational assumptions for the month (the “ Operational
      Assumptions ”),
      including without limitation the weighted average number of Covered Aircraft,
      estimated passengers, revenue passenger miles, departures, block hours, and
      flights hours, based on the Final Monthly Schedule, no later than two Business
      Days following receipt of RAI’s comments to the preliminary schedule. Following
      delivery of the Final Monthly Schedule, however, Frontier may make such
      adjustments to the proposed Final Monthly Schedule as it deems appropriate
      (subject to Reasonable Operating Constraints).




*(c)*  *Wet
      Leases* .
      At
      Frontier's option, and provided that RAI is not adversely affected in any
      material respect, RAI shall “wet lease” one or more of the Covered Aircraft to
      Frontier, on terms mutually acceptable to the parties hereto, which terms are
      identical in all material respects, economically and otherwise, to the terms
      of
      this Agreement (taking into account the inherent differences between a “wet
      lease” arrangement and a capacity purchase arrangement), and such “wet lease”
shall supersede the capacity purchase provisions of this Agreement with respect
      to such Covered Aircraft. In such event, RAI's compensation hereunder, including
      without limitation in this Article
      II ,
      in Article
      III and in Exhibit
      D ,
      shall
      be adjusted so that RAI's aggregate compensation from such “wet lease”
arrangements and the capacity purchase arrangements applicable to the remaining
      Covered Aircraft are equal to the amount of RAI's aggregate compensation had
      no
      such “wet lease” arrangements been entered into.




*(d)*  *Start
      Up Dates* .
      The
      Covered Aircraft shall be placed into service under the terms and conditions
      of
      this Agreement on such dates as are provided on Exhibit B .




*(e)*  *Spare
      Aircraft* .
      The
      Spare Aircraft constituting a Covered Aircraft shall be used by RAI solely
      as an
      operational and maintenance spare to replace Covered Aircraft that are out
      of
      service due to scheduled maintenance or to cover for other irregular operations,
      provided, RAI may use the Spare Aircraft for flights operated for its own
      benefit or to cover flights for any other airline subject to the following
      conditions:





(1)  Frontier
      will have the right to designate which of the first twelve Covered Aircraft
      will
      be the Spare Aircraft no later than the inservice date of the twelfth Covered
      Aircraft, such designation to be provided to RAI in writing no fewer than 90
      days prior to the inservice date of the aircraft to be designated as the Spare
      Aircraft.





(2)  The
      Spare
      Aircraft will be in a neutral livery as set forth in Exhibit C to this Agreement
      and configured in accordance with the Frontier specifications set forth in
      Exhibit C and its principal base of operations will be Denver International
      Airport.





(3)  The
      Spare
      Aircraft will be pooled with other neutral spare aircraft operated by RAI for
      other air carriers (the “ Pool
      Participants ”)
      and
      will be available for use by RAI to cover flying for Pool Participants due
      to
      irregular operations, aircraft damage, or maintenance events incurred by Pool
      Participants. RAI shall give Frontier notice of its intent to use the Spare
      Aircraft as early as operationally possible. If necessary, Frontier will apprise
      RAI of its operational situation related to re-deployment of the Spare Aircraft.
      Nothwithstanding the above, Frontier acknowledges and agrees that RAI will
      at
      all times retain operational control of the Spare Aircraft.





(4)  Regardless
      of RAI’s use of the Spare Aircraft to cover flights of Pool Participants, the
      Spare Aircraft will be considered a Covered Aircraft for purposes of calculating
      Frontier’s Fixed Costs. Frontier will not be obligated to pay or reimburse RAI
      for any Variable Costs or Pass-Thru Costs relating to (i) the ferrying of the
      Spare Aircraft to and from locations necessary to cover flying for other Pool
      Participants, or (ii) the covered flying itself. Fixed Costs, Variable Costs
      and
      Pass-Thru Costs as used in this paragraph are as described on Exhibit
      D .





(5)  In
      consideration of Frontier making the Spare Aircraft available for flights
      operated by Pool Participants according to this Section, Frontier will be
      entitled to use the neutral spare aircraft contributed to the pool by other
      Pool
      Participants, *provided* ,
      Frontier will be responsible for the payment of Variable Costs and Pass-Thru
      Costs relating to (i) the ferrying of the neutral spare aircraft to and from
      the
      location necessary to cover for Frontier Scheduled Flights, and (ii) the covered
      Scheduled Flights, provided further, Frontier will not be responsible under
      Section 2.01 (e)(5)(i) if the neutral aircraft is being ferried to cover for
      flights canceled or delayed due to aircraft damage caused by RAI, its agents,
      contractors or employees.





(6)  Frontier
      will have the right, in its sole discretion, to remove the Spare Aircraft from
      the neutral spare pool at any time during the period from the date the Spare
      Aircraft first entered the neutral aircraft pool until the first anniversary
      thereof by providing RAI with 30 days advance written notice. Should the Spare
      Aircraft be removed from the neutral aircraft pool, (i) RAI will incur all
      costs
      to convert the aircraft livery to the Frontier livery set forth in Exhibit
      C,
      and (ii) from and after the date of removal, the Spare Aircraft will be
      dedicated to supporting Frontier’s Scheduled Flights and will no longer be
      available for use by RAI to cover flights for itself or any other airline and
      Frontier shall no longer have the use of the neutral spare aircraft of any
      Pool
      Participant for Regional Airline Services.


*(f)* *Fleet
      Expansion* .
      During
      the term of this Agreement, RAI will advise Frontier of any regional jet
      aircraft that RAI believes will become available, whether due to RAI option
      positions, the return of aircraft previously in service for another airline,
      or
      the removal of the aircraft from RAI's own fleet, or otherwise, for potential
      inclusion in the Frontier fleet of Covered Aircraft. ** Notwithstanding
      the foregoing, such regional jet aircraft shall only be deemed a Covered
      Aircraft upon an amendment to this Agreement.




*Section
      2.02*  *Flight-Related
      Revenue.* RAI
      acknowledges and agrees that all revenues resulting from the sale and issuance
      of passenger tickets associated with the operation of the Covered Aircraft
      and
      all other sources of revenue associated with the operation of the Covered
      Aircraft, including without limitation fees related to ticket changes,
      unaccompanied minors, excess baggage and nonrevenue pass travel, revenues
      relating to the transportation of cargo or mail, and revenues associated with
      food, beverage, passenger entertainment, duty-free services, and guaranteed
      or
      incentive payments from airport, local or municipal authorities in connection
      with scheduling flights to such airport or locality, are the sole property
      of
      and shall be retained by Frontier (or, if received by RAI, shall be promptly
      accounted for and remitted to Frontier).




*Section
      2.03*  *Pass

      maintenance personnel traveling to provide critical repair services and dead
      heading RAI crews will be entitled to travel on flights operated by RAI or
      Frontier as must ride passengers. Commuting RAI crew members and all other
      RAI
      employees will be entitled to travel on Frontier and Frontier JetExpress flights
      at a priority category one level below the lowest category for Frontier
      employees and subject to the fare policies applicable to individuals traveling
      at that priority level. To the extent permitted by existing arrangements,
      Frontier employees will be entitled to (x) travel on Scheduled Flights operated
      by RAI under the category of travel and fare policies to which they are entitled
      to travel on Frontier flights, and (y) will be entitled to travel on all other
      RAI operated flights at a category one level below the lowest category for
      RAI
      employees.




*Section
      2.04*  *Conversion
      of Covered Aircraft.* RAI will
      be responsible for all costs and expenses of preparing each Covered Aircraft
      prior to its being placed into service hereunder in accordance with the
      specifications, cabin configurations and livery as required by Exhibit
      C ,
      provided, it is expressly understood that the first four aircraft scheduled
      to
      be placed in service under Exhibit
      C (the
      "Two-Class Aircraft") will be placed in service on the dates indicated in RAI’s
      two-class 70-seat configuration. RAI, at its sole cost and expense, will convert
      the Two-Class Aircraft to the specifications, cabin configurations and livery

      RAI has
      and shall maintain all certifications, permits, licenses, certificates,
      exemptions, approvals, plans, and insurance required by governmental
      authorities, including, without limitation, FAA, DOT and TSA, to enable RAI
      to
      perform the services required by this Agreement. All flight operations, dispatch
      operations and all other operations and services undertaken by RAI pursuant
      to
      this Agreement shall be conducted, operated and provided by RAI in compliance
      with all U.S. and foreign governmental laws, regulations and requirements,
      including, without limitation, those relating to airport security, the use
      and
      transportation of hazardous materials and dangerous goods, crew qualifications,

      compliance with all laws, regulations and governmental requirements, RAI's
      own
      operations manuals and maintenance manuals and procedures, and all applicable
      equipment manufacturers' manuals and instructions.




*Section
      4.03*  *Quality
      of Service* *.* At all
      times, RAI shall provide Regional Airline Services with appropriate standards
      of
      care, but in no event lower than such standards held by Frontier as of the
      date
      of this Agreement. Frontier procedures, performance standards and means of
      measurement thereof concerning the provision of air passenger and air cargo
      services shall be applicable to all Regional Airline Services provided by RAI.
      RAI shall achieve at least the comparable quality of airline service as provided
      by Frontier, subject to limitations imposed by the type of aircraft used by
      RAI
      and its route network. RAI shall comply with all airline customer service
      commitments and policies of Frontier as of the date hereof, including without
      limitation the employee conduct, appearance and training policies in place
      as of
      the date hereof, and shall handle customer-related services in a professional,
      businesslike and courteous manner. In connection therewith, RAI shall maintain
      aircraft cleaning cycles and policies, and shall maintain adequate staffing
      levels, to achieve a level of operations that routinely meet or exceed the
      on-time performance Target Threshold and the completion factor Target Threshold
      as set forth in Appendix
      2 to Exhibit
      D .
      RAI
      shall provide Frontier with timely communication regarding the status of all
      Scheduled Flights. At either party's request, RAI and Frontier will meet to
      discuss and review RAI's customer service and handling procedures and policies
      and its employees' conduct, appearance and training standards and policies.
      Frontier shall give RAI not less than 15 days prior written notice of any
      non-safety-related breach of this Section
      4.03 prior to
      exercising any remedy regarding such breach.




*Section
      4.04*  *Incidents
      or Accidents.* RAI
      shall promptly notify Frontier of all irregularities involving a Scheduled
      Flight or Covered Aircraft operated by RAI, including, without limitation,
      aircraft accidents and incidents, which result in any damage to persons and/or
      property or may otherwise result in a complaint or claim by passengers or an
      investigation by a governmental agency or authority. RAI shall furnish to
      Frontier as much detail as practicable concerning such irregularities and shall
      cooperate with Frontier at RAI's own expense in any appropriate
      investigation.




*Section
      4.05*  *Emergency
      Response.* RAI
      shall adopt Frontier's Emergency Response Plan for aircraft accidents or
      incidents. In the event of an accident or incident involving a Covered Aircraft
      or Scheduled Flight, Frontier will have the right to manage the emergency
      response efforts on behalf of RAI with full cooperation from RAI and if such
      right is exercised, RAI acknowledges and agrees that Frontier representatives
      will conduct all public communications, and that RAI will make no public
      statements, regarding such accident or incident.




*Section
      4.06*  *Safety
      Matters.* In
      the event of a reasonable safety concern, Frontier shall have the right, at
      its
      own cost, to inspect, review, and observe RAI's operations of Scheduled Flights.
      Notwithstanding the conduct or absence of any such review, RAI is and shall
      remain solely responsible for the safe operation of its aircraft and the safe
      provision of Regional Airline Services, including all Scheduled Flights, and
      nothing in this Section 4.06 or otherwise in this Agreement is intended or
      shall
      be interpreted to make Frontier responsible for such safety
      matters.




*Section
      4.07*  *Codeshare
      Terms.* RAI
      agrees to operate all Scheduled Flights using the Frontier flight code and
      flight numbers assigned by Frontier, or such other flight codes and flight
      numbers as may be assigned by Frontier (to accommodate, for example, a Frontier
      alliance partner), and otherwise under the codeshare terms set forth in Exhibit
      E .




*Section
      4.08*  *Slots and Route Authorities.* Should
      Frontier schedule Covered Aircraft on international routes, Frontier will
      provide RAI notice of such intent no fewer than 150 days in advance of the
      intended start date. To the extent permitted under applicable laws and
      regulations, Frontier will obtain the necessary slots, route authorities or
      other approval required for such service at its own cost and expense, provided
      such items may be held and controlled by Frontier. If it is required that RAI,
      as the operator of the Scheduled Flights, obtain the authorities and approvals,
      or if Frontier is prohibited from holding such authorities and approvals in
      its
      own name, RAI will use its commercially reasonable efforts to obtain all
      necessary licenses, permits, route authorities or slots and complete all
      necessary filings and registrations, all at RAI’s sole cost and expense, in
      order to initiate such service. During the Term, RAI will operate Scheduled
      Flights on these routes solely on behalf of Frontier. At the request of Frontier
      made during the Term or upon termination of this Agreement, so long as Frontier
      is not in breach of a material obligation under this Agreement, RAI shall use
      its commercially reasonable efforts to transfer to Frontier or its designee,
      to
      the extent permitted by law, any airport takeoff or landing slots, route
      authorities or other similar regulatory authorizations held by RAI in connection
      with Scheduled Flights, or held or acquired by RAI and used for Scheduled
      Flights, in consideration of the payment to RAI of the reasonable, documented
      out of pocket expenses incurred by RAI in order to obtain such transferred
      rights, authorities and slots. Frontier will be responsible for all costs and
      expenses relating to such assignment, including without limitation reasonable
      attorneys’ fees. RAI's obligations herein shall survive the termination of this
      Agreement for so long as any transfer requested pursuant to this Section
      4.08 shall
      not have been completed. RAI hereby agrees that all of RAI's contacts or
      communications with any applicable regulatory authority concerning any airport
      takeoff or landing slots, route authorities or other similar regulatory
      authorizations used for Scheduled Flights will be coordinated through Frontier.
      If any airport takeoff or landing slot, route authority or other similar
      regulatory authorization transferred to RAI by Frontier for use in connection
      with Scheduled Flights, or held by RAI and used for Scheduled Flights, is
      withdrawn or otherwise forfeited as a result of circumstances or events within
      RAI's reasonable control, then RAI agrees (i) to purchase a reasonably
      acceptable replacement slot, route authority or other similar regulatory
      authorization, or (ii) to pay to Frontier promptly upon demand an amount equal
      to the greater of (y) [ *  ]of
      the
      revenue loss for [*] days after the date such slot, authority or authorization
      is withdrawn or forfeited, or (z) the interrupted trip expense and
      reaccommodation costs incurred by Frontier due to the withdrawal or forfeiture
      of the slot, authority or authorization.

      written consent of Frontier, except with respect to the Spare Aircraft as

INSURANCE





*Section
      6.01*  *Minimum
      Insurance Coverages.* During
      the Term, in addition to any insurance required to be maintained by RAI pursuant
      to the terms of any aircraft lease, or by any applicable governmental or airport
      authority, RAI shall maintain, or cause to be maintained, in full force and
      effect policies of insurance with insurers of recognized reputation and
      responsibility, in each case to the extent available on a commercially
      reasonable basis, as follows:




(a)  Comprehensive
      airline liability insurance, including bodily injury and personal injury, third
      party propery damage, passenger liability (including passengers' baggage and
      personal effects), cargo and mail legal liability, for a combined single limit
      of not less than **** [ *  ]
      per
      occurrence (or whatever higher amount RAI may carry from time to time), limited
      in the case of personal injury to [*] per occurrence and in the aggregate
      (except with respect to passengers to whom the full policy limit applies),
      and War Risk liability insurance as per London form AVN.52E or current
      equivalent, or as provided by the Federal Aviation Administration program,
      with
      a combined single limit no less than **** [*]
      per
      occurrence (or whatever higher amount RAI may carry from time to
      time);





(b)
      All
      Risk Hull Insurance on aircraft performing services hereunder, insured on an
      agreed value basis with standard market deductibles, including hull war coverage
      as per London form LSW 555 or equivalent, or as provided by the Federal Aviation
      Administration program.




(c)  Workers'
      compensation as required by the appropriate jurisdiction and employer's
      liability with a limit of not less than **** [*]
      combined single limit; and




(d)  Other
      property and liability insurance coverages of the types and in the amounts
      that
      would be considered reasonably prudent for a business organization of RAI's
      size
      and nature, under the insurance market conditions in effect at the time of
      placement, but in any event of the type and the amount that Frontier may
      reasonably require to prevent or minimize a disruption in the provision of
      Regional Airline Services resulting from a casualty or liability incident
      related to RAI's operations. All coverages described in this Section
      6.01 shall be
      placed with deductibles reasonably prudent for a business organization of RAI's
      size and nature, under the insurance market conditions in effect at the time
      of
      placement.




*Section
      6.02*  *Endorsements.* RAI
      shall cause the policies described in Section
      6.01 to be
      duly and properly endorsed by RAI's insurance underwriters with respect to
      RAI's
      flights and operations as follows:





(a)
      with
      respect to liability coverage to provide that Frontier, and its directors,
      officers, agents, employees and other authorized representatives shall be
      endorsed as additional insured parties;




(b)  To
      provide that the underwriters shall waive subrogation rights against Frontier,
      its directors, officers, agents, employees and other authorized
      representatives;




(c)  with
      respect to liability coverage, to provide that insurance shall be primary to
      and
      without right of contribution from any other insurance which may be available
      to
      the additional insureds;




(d)  To
      include a breach of warranty provision in favor of the additional
      insureds;




(e)  To
      accept and insure RAI's hold harmless and indemnity undertakings set forth
      in
      this Agreement, but only to the extent of the coverage afforded by the policy
      or
      policies;





(f)
      with
      respect to liability coverages to provide that the inclusion of more than one
      corporation, person, organization, firm or entity as Insured under the policies
      shall not in any way affect the rights of any such corporation, person,
      organization, firm or entity either as respects any claim, demand, suit, or
      judgment made, brought or recovered by or in favor of any other Insured, or
      by
      or in favor of any employee of such other Insured. The policy shall protect
      each
      corporation, person, organization, firm or entity in the same manner as though
      a
      separate policy had been issued to each. Nothing herein shall operate to
      increase the liability of the insurers as set forth in the policies beyond
      the
      amount for which the insurers would have been liable if only one person or
      interest had been included as an insured.




(g)  To
      provide that such policies shall not be canceled, terminated or materially
      altered, changed or amended until 30 days (but seven days or such lesser period
      as may be available in respect of hull, war and allied perils) after written
      notice shall have been sent to Frontier.




*Section
      6.03*  *Evidence
      of Insurance Coverage.* At the
      commencement of this Agreement, and thereafter at Frontier's request, RAI shall
      furnish to Frontier evidence reasonably satisfactory to Frontier of such
      insurance coverage and endorsements, including certificates certifying that
      such
      insurance and endorsements are in full force and effect. Initially, this
      evidence shall be a certificate of insurance. If RAI fails to acquire or
      maintain insurance as herein, *provided* ,
      Frontier may at its option secure such insurance on RAI's behalf at RAI's
      expense.

      employees.




*Section
      7.03*  *Indemnification
      Claims.* A party
      entitled to indemnification (the “ Indemnified
      Party ”)
      from
      another party under the terms of this Agreement (the “ Indemnifying
      Party ”)
      shall
      provide the Indemnifying Party with prompt written notice (an “ Indemnity
      Notice ”)
      of any
      third party claim which the Indemnified Party believes gives rise to a claim
      for
      indemnity against the Indemnifying Party hereunder. The Indemnifying Party
      shall
      be entitled, if it accepts financial responsibility for the third party claim,
      to control the defense of or to settle any such third party claim at its own
      expense and by its own counsel; *provided* that the
      Indemnified Party's prior written consent (which may not be unreasonably
      withheld or delayed) must be obtained prior to settling any such third party
      claim. The Indemnified Party shall provide the Indemnifying Party with such
      information as the Indemnifying Party shall reasonably request to defend any
      such third party claim and shall otherwise cooperate with the Indemnifying
      Party
      in the defense of any such third party claim. Except as set forth in this Section
      7.03 ,
      the
      Indemnified Party shall not enter into any settlement or other compromise or
      consent to a judgment with respect to a third party claim as to which the
      Indemnifying Party has an indemnity obligation hereunder without the prior
      written consent of the Indemnifying Party (which may not be unreasonably
      withheld or delayed), and the entering into of any settlement or compromise
      or
      the consent to any judgment in violation of the foregoing shall constitute
      a
      waiver by the Indemnified Party of its right to indemnity hereunder to the
      extent the Indemnifying Party was prejudiced thereby. Any Indemnifying Party
      shall be subrogated to the rights of the Indemnified Party to the extent that
      the Indemnifying Party pays for any loss, damage or expense suffered by the
      Indemnified Party hereunder. If the Indemnifying Party does not accept financial
      responsibility for the third party claim or fails to defend against the third
      party claim that is the subject of an Indemnity Notice within 30 days of
      receiving such notice (or sooner if the nature of the third party claim so
      requires), or otherwise contests its obligation to indemnify the Indemnified
      Party in connection therewith, the Indemnified Party may, upon providing written
      notice to the Indemnifying Party, pay, compromise or defend such third party
      claim without the prior consent of the (otherwise) Indemnifying Party. In the
      latter event, the Indemnified Party, by proceeding to defend itself or settle
      the matter, does not waive any of its rights hereunder to later seek
      reimbursement from the Indemnifying Party.




*Section
      7.04*  *Employer's
      Liability; Independent Contractors; Waiver of Control*




*(a)*  *Employer's
      Liability and Workers' Compensation* .
      Each
      party hereto assumes full responsibility for its employer's and workers'
      compensation liability to its respective officers, directors, employees or
      agents on account of injury or death resulting from or sustained in the
      performance of their respective service under this Agreement. Each party, with
      respect to its own employees, accepts full and exclusive liability for the
      payment of workers' compensation and employer's liability insurance premiums
      with respect to such employees, and for the payment of all taxes, contributions
      or other payments for unemployment compensation or old age or retirement
      benefits, pensions or annuities now or hereafter imposed upon employers by
      the
      government of the United States or any other governmental body, including state,
      local or foreign, with respect to such employees measured by the wages,
      salaries, compensation or other remuneration paid to such employees, or
      otherwise.




*(b)*  *Employees,
      etc., of RAI* .
      The
      employees, agents, and independent contractors of RAI engaged in performing
      any
      of the services RAI is to perform pursuant to this Agreement are employees,
      agents, and independent contractors of RAI for all purposes, and under no
      circumstances will be deemed to be employees, agents or independent contractors
      of Frontier. In its performance under this Agreement, RAI will act, for all
      purposes, as an independent contractor and not as an agent for Frontier.
      Notwithstanding the fact that RAI has agreed to follow certain procedures,
      instructions and standards of service of Frontier pursuant to this Agreement,
      Frontier will have no supervisory power or control over any employees, agents
      or
      independent contractors engaged by RAI in connection with its performance
      hereunder, and all complaints or requested changes in procedures made by
      Frontier will, in all events, be transmitted by Frontier to RAI's designated
      representative. Nothing contained in this Agreement is intended to limit or
      condition RAI's control over its operations or the conduct of its business
      as an
      air carrier.








*(c)*  *Employees,
      etc., of Frontier* .
      The
      employees, agents, and independent contractors of Frontier engaged in performing
      any of the services Frontier is to perform pursuant to this Agreement are
      employees, agents, and independent contractors of Frontier for all purposes,
      and
      under no circumstances will be deemed to be employees, agents, or independent
      contractors of RAI. RAI will have no supervision or control over any such
      Frontier employees, agents and independent contractors and any complaint or
      requested change in procedure made by RAI will be transmitted by RAI to
      Frontier's designated representative. In its performance under this Agreement,
      Frontier will act, for all purposes, as an independent contractor and not as
      an
      agent for RAI.




*(d)*  *RAI
      Flights* .
      The
      fact that RAI's operations are conducted under Frontier's Marks and listed
      under
      the F9 designator code will not affect their status as flights operated by
      RAI
      for purposes of this Agreement or any other agreement between the parties,
      and
      RAI and Frontier agree to advise all third parties, including passengers, of
      this fact.




*Section
      7.05*  *Survival* The
      provisions of this Article
      VII shall
      survive the termination of this Agreement for a period of seven
      years.







ARTICLE
      VIII  TERM, TERMINATION AND DISPOSITION OF AIRCRAFT




*Section
      8.01*  *Term.* The Term
      of this Agreement shall commence on and shall be effective as of the Effective
      Date and, unless earlier terminated for Cause or breach or extended as provided
      herein, shall continue until the eleventh (11 th )
      anniversary of the date the last Covered Aircraft was placed into service,
      as
      such date may be extended pursuant to Section
      10.17 hereof
      (the “ Term ”).




*Section
      8.02*  *Early
      Termination*




*(a)*  *By
      Frontier for Cause* .
      Frontier shall have the right to terminate this Agreement upon written notice
      following the occurrence of any event that constitutes Cause. Any termination
      pursuant to this Section
      8.02(a) shall
      supersede any other termination pursuant to any other provision of this
      Agreement (even if such other right of termination shall already have been
      exercised) The notice of termination provided by Frontier pursuant to this Section
      8.02(a) shall
      designate a termination date (which may be any date between the date of the
      notice and a date no more than 120 days of the date of the notice) and will
      also
      indicate whether or not Frontier intends to submit a Wind-Down Schedule pursuant
      to Section
      8.03(a) ,
      and the
      termination date set forth in the notice provided by Frontier will be the
      Termination Date for purposes of this Agreement (and such Termination Date
      pursuant to this Section
      8.02(a) shall
      supersede any other Termination Date that may have been previously established
      pursuant to another termination). In the event that Frontier shall not have
      delivered written notice of termination pursuant to this Section
      8.02(a) within
      45
      days after Frontier receives written notice from RAI of the occurrence of any
      event that constitutes Cause by RAI, then Frontier shall be conclusively deemed
      to have waived any right to terminate this Agreement based upon such
      event; *provided* that
      such waiver shall not apply to any subsequent or continuing event that
      constitutes Cause.




*(b)*  *By
      Frontier for Breach* .
      Frontier may terminate this Agreement, upon two Business Days’ prior written
      notice, upon the occurrence of (A) a material breach of this Agreement by RAI
      as
      described in clause
      (i) below,
      which breach shall not have been cured within such two Business Day period,
      or
      (B) a breach by RAI of its covenant contained in Section
      5.04 .
      Frontier may also terminate this Agreement upon the occurrence of any other
      material breach of this Agreement by RAI, which breach shall not have been
      cured
      within 60 days after written notice of such breach is delivered by Frontier
      to
      RAI (which 60-day notice period may run concurrently with the 15-day notice
      period, if any, provided pursuant to Section
      4.03 for
      non-safety-related breaches). Any termination notice provided by Frontier
      pursuant to this Section
      8.02(b) shall
      specify a Termination Date that will be no more than 90 days from the date
      of
      such notice. The parties hereto agree that, without limiting the circumstances
      or events that may constitute a material breach, each of the following shall
      constitute a material breach of this Agreement by RAI: (i) a reasonable and
      good
      faith determination by Frontier, using recognized standards of safety, that
      there is a material safety concern with the operation of any Scheduled Flights,
      or (ii) the grounding of the Covered Aircraft by regulatory or court order
      or
      other governmental action. In the event that Frontier shall not have delivered
      written notice of termination pursuant to this Section
      8.02(b) within
      45 days after Frontier receives written notice from RAI of any material breach
      of this Agreement by RAI, then Frontier shall be conclusively deemed to have
      waived any right to terminate this Agreement based upon such breach; *provided* that
      such waiver shall not apply to any subsequent or continuing breach.




*(c)*  *By
      RAI for Breach* .
      RAI may
      terminate this Agreement upon (i) five Business Days prior written notice upon
      (A) any failure by Frontier to make any payment or payments under this Agreement
      aggregating in excess of **** [ *  ],
      including without limitation, any payments which become due during any Wind-Down
      Period, but specifically excluding any amounts which are the subject of a good
      faith dispute between the parties, which failure shall not have been cured
      within five Business Days after written notice of such failure is delivered
      by
      RAI to Frontier, or (B) a breach by Frontier of its covenant contained in Section
      5.04 ,
      (ii)
      the occurrence of any other failure by Frontier to make any payment or payments
      under this Agreement aggregating in excess of **** [*],
      including without limitation, any payments which become due during any Wind-Down
      Period, but specifically excluding any amounts which are the subject of a good
      faith dispute between the parties, which failure shall not have been cured
      within 20 days after written notice of such breach is delivered by RAI to
      Frontier, or (iii) the occurrence of any other material breach of this Agreement
      by Frontier, including without limitation, any breach during any Wind-Down
      Period, which breach shall not have been cured within 60 days after written
      notice of such breach is received by Frontier. In the event that RAI shall
      not
      have delivered written notice of termination pursuant to this Section
      8.02(c) within
      45 days after RAI receives written notice from Frontier of any material breach
      of this Agreement by Frontier, then RAI shall be conclusively deemed to have
      waived any right to terminate this Agreement based upon such breach; *provided* that
      such waiver shall not apply to any subsequent or continuing breach.




*(d)* *Survival
      During Wind-Down Period* .
      Notwithstanding the Termination Date indicated in any notice of termination
      provided by either party pursuant to this Agreement, upon any termination
      hereunder where a party has elected to provide a Wind-Down Schedule, the Term
      shall continue, and this Agreement shall survive in full force and effect,
      beyond the Termination Date until the end of the Wind-Down Period, if any,
      and
      the rights and obligations of the parties under this Agreement, including
      without limitation remedies available upon the occurrence of events constituting
      Cause or material breach, shall continue with respect to the Covered Aircraft
      until the final Covered Aircraft is withdrawn from this Agreement.





*Section
      8.03*  *Disposition
      of Aircraft during Wind-Down Period*





*(a)*  *Termination
      by Frontier for Cause* .
      If this
      Agreement is terminated pursuant to Section 8.02(a) ,
      the
      Covered Aircraft shall be completely withdrawn from the capacity purchase
      provisions of this Agreement as of the Termination Date and shall cease to
      be
      Covered Aircraft as of such date, unless the notice of termination provided
      by
      Frontier under Section
      8.02(a) indicates that Frontier intends to submit a Wind-Down Schedule. In such event
      within 120 days of sending the notice of termination pursuant to Section
      8.02(a) ,
      Frontier will provide an irrevocable Wind-Down Schedule according to which
      the
      Covered Aircraft will be withdrawn from the capacity purchase provisions of
      this
      Agreement. The Wind-Down Schedule will provide for the withdrawal of the Covered
      Aircraft no sooner than the Termination Date and no later than 24 months from
      the Termination Date. The provisions of this Section 8.03(a) shall
      supersede any Wind-Down Schedule delivered pursuant to any other provision
      of
      this Agreement.

      not
      be more than [ *  ]
      Covered
      Aircraft per month.

      If this
      Agreement is terminated by RAI under Section

      then
      the Covered Aircraft shall be withdrawn from the capacity purchase provisions
      of
      this Agreement in accordance with the following terms and conditions: The notice
      of termination delivered by RAI to Frontier pursuant to Section 8.02(c)(i) shall be

      8.02(c)(i) .
      As of
      the Termination Date set forth in a notice of termination delivered pursuant

ARTICLE
      IX  REPRESENTATIONS, WARRANTIES AND COVENANTS




*Section
      9.01*  *Representations
      and Warranties of RAI.* RAI
      represents and warrants to Frontier as of the date hereof as
      follows:




*(a)*  *Organization
      and Qualification* .
      RAI is
      a duly organized and validly existing corporation under the laws of the State
      of
      Indiana. RAI has the corporate power and authority to own, operate and use
      its
      assets and to provide the Regional Airline Services. RAI is duly qualified
      to do
      business as a foreign corporation under the laws of each jurisdiction that
      requires such qualification, except where the failure to possess such
      qualification would not have a material adverse effect on RAI or its ability
      to
      conduct its business, to provide Regional Airline Services, and otherwise to
      perform its obligations hereunder.




*(b)*  *Authority
      Relative to this Agreement* .
      RAI has
      the corporate power and authority to execute and deliver this Agreement and
      to
      consummate the transactions contemplated hereby in accordance with the terms
      hereof. The execution and delivery of this Agreement and the consummation of
      the
      transactions contemplated hereby have been duly authorized by all necessary
      corporate action on the part of RAI. This Agreement has been duly and validly
      executed and delivered by RAI and is, assuming due execution and delivery
      thereof by Frontier and that Frontier has legal power and right to enter into
      this Agreement, a valid and binding obligation of RAI, enforceable against
      RAI
      in accordance with its terms, except as enforcement hereof may be limited by
      bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and
      other similar laws relating to or affecting the enforcement of creditors' rights
      generally and legal principles of general applicability governing the
      availability of equitable remedies (whether considered in a proceeding in equity
      or at law or otherwise under applicable law).




*(c)*  *Conflicts* .
      Neither
      the execution or delivery of this Agreement nor the performance by RAI of the
      transactions contemplated hereby will (i) violate, conflict with, or constitute
      a default under any of the terms of RAI's certificate of incorporation, by-laws,
      or any provision of, or result in the acceleration of any obligation under,
      any
      material contract, sales commitment, license, purchase order, security
      agreement, mortgage, note, deed, lien, lease or other agreement to which RAI
      is
      a party or by which it or any of its properties or assets may be bound, (ii)
      result in the creation or imposition of any lien, charge or encumbrance in
      favor
      of any third person or entity, (iii) violate any law, statute, judgment, decree,
      order, rule or regulation of any governmental authority or body, or (iv)
      constitute any event which, after notice or lapse of time or both, would result
      in such violation, conflict, default, acceleration or creation or imposition
      of
      liens, charges or encumbrances.




*(d)*  *No
      Default* .
      RAI is
      not (i) in violation of its charter or by-laws, (ii) in breach or
      default in any material respect, and no event has occurred which, with notice
      or
      lapse of time or both, would constitute such a breach or default, in the due
      performance or observance of any term, covenant or condition contained in any
      indenture, mortgage, deed of trust, loan agreement or other agreement or
      instrument to which it is a party or by which it is bound or to which any of
      its
      properties or assets is subject or (iii) in violation of any law,
      ordinance, governmental rule, regulation or court decree to which it or its
      property or assets may be subject or has failed to obtain any material license,
      permit, certificate, franchise or other governmental authorization or permit
      necessary to the ownership of its property or to the conduct of its business,
      where such violation, breach, default or failure would have a material adverse
      effect on RAI or on its ability to provide Regional Airlines Services and
      otherwise perform its obligations hereunder. To the knowledge of RAI, no third
      party to any indenture, mortgage, deed of trust, loan agreement, lease or other
      agreement or instrument that is material to RAI to which RAI is a party or
      by
      which any of them are bound or to which any of their properties are subject,
      is
      in default in any material respect under any such agreement.




*(e)*  *Broker* .
      RAI has
      not retained or agreed to pay any broker or finder with respect to this
      Agreement and the transactions contemplated hereby.




*(f)*  *Financial
      Statements* .
      The
      financial statements (including the related notes and supporting schedules)
      of
      RAI Holdings delivered (or, if filed with the Securities and Exchange
      Commission, made available) to Frontier immediately prior to the date hereof
      fairly present in all material respects the consolidated financial position
      of
      RAI Holdings and its results of operations as of the dates and for the periods
      specified therein. Since the date of the latest of such financial statements,
      there has been no material adverse change nor any development or event involving
      a prospective material adverse change with respect to RAI Holdings. Such
      financial statements have been prepared in accordance with generally accepted
      accounting principles in the United States consistently applied throughout
      the
      periods involved, except to the extent disclosed therein.




*(g)*  *Insurance* .
      RAI is
      insured by insurers of recognized financial responsibility against such losses
      and risks and in such amounts and with such deductibles as are customary in
      the
      businesses in which they are engaged. RAI has not received notice of
      cancellation or non-renewal of such insurance. All such insurance is outstanding
      and duly in force on the date hereof. RAI has no reason to believe that it
      will
      not be able to renew its existing insurance coverage as and when such coverage
      expires or to obtain similar coverage from similar insurers as may be necessary
      to continue its business at a cost that would not have a material adverse effect
      on RAI.




*(h)*  *No
      Proceedings* .
      There
      are no legal or governmental proceedings pending, or investigations commenced
      of
      which RAI has received notice, in each case to which RAI is a party or of which
      any property or assets of RAI is the subject which, if determined adversely
      to
      RAI, would individually or in the aggregate have a material adverse effect
      on
      RAI or on RAI's ability to provide Regional Airlines Services and otherwise
      perform its obligations hereunder; and to the best knowledge of RAI, no such
      proceedings are threatened or contemplated by governmental authorities or
      threatened by others.





*(i)*  *No
      Labor Dispute* .
      No
      labor dispute with the employees of RAI exists or, to the knowledge of RAI,
      is
      imminent which would reasonably be expected to have a material adverse effect
      on
      RAI or on its ability to provide Regional Airlines Services and otherwise
      perform their respective obligations hereunder.




*(j)*  *Permits* .
      Other
      than FAA certification for over-water operations, which certification RAI
      intends to obtain prior to the inservice date of the fifth Covered Aircraft,
      RAI
      possesses all material certificates, authorizations and permits issued by FAA
      and other applicable federal, state or foreign regulatory authorities necessary
      to conduct their respective businesses, to provide Regional Airlines Services
      and otherwise to perform their respective obligations hereunder, and RAI has
      not
      received any notice of proceedings relating to the revocation or modification
      of
      any such certificate, authorization or permit which, individually or in the
      aggregate, if the subject of an unfavorable decision, ruling or finding, would
      result in a material adverse effect on RAI or on its ability to conduct its
      businesses, to provide Regional Airlines Services and otherwise to perform
      its
      obligations hereunder.

      or
      creation or imposition of liens, charges or encumbrances.

      by a notice in writing in accordance with this Section 10.02 .


*Section
      10.03*  *Binding
      Effect; Assignment.* This
      Agreement and all of the provisions hereof shall be binding upon the parties
      hereto and inure to the benefit of the parties hereto and their respective
      successors and permitted assigns. Except with respect to a merger or other
      consolidation of either party with another Person (and without limiting
      Frontier's and RAI’s respective rights pursuant to Section
      5.03 hereof),
      neither this Agreement nor any of the rights, interests or obligations hereunder
      shall be assigned by any party hereto without the prior written consent of
      the
      other parties.




*Section
      10.04*  *Amendment
      and Modification.* This
      Agreement may not be amended or modified in any respect except by a written
      agreement signed by the parties hereto that specifically states that it is
      intended to amend or modify this Agreement.




*Section
      10.05*  *Waiver.* The
      observance of any term of this Agreement may be waived (either generally or
      in a
      particular instance and either retroactively or prospectively) by the party
      entitled to enforce such term, but such waiver shall be effective only if it
      is
      in writing signed by the party against which such waiver is to be asserted
      that
      specifically states that it is intended to waive such term. Unless otherwise
      expressly provided in this Agreement, no delay or omission on the part of any
      party in exercising any right or privilege under this Agreement shall operate
      as
      a waiver thereof, nor shall any waiver on the part of any party of any right
      or
      privilege under this Agreement operate as a waiver of any other right or
      privilege under this Agreement nor shall any single or partial exercise of
      any
      right or privilege preclude any other or further exercise thereof or the
      exercise of any other right or privilege under this Agreement. No failure by
      any
      party to take any action or assert any right or privilege hereunder shall be
      deemed to be a waiver of such right or privilege in the event of the
      continuation or repetition of the circumstances giving rise to such right unless
      expressly waived in writing by each party against whom the existence of such
      waiver is asserted.








*Section
      10.06*  *Interpretation.* The
      table of contents and the section and other headings and subheadings contained
      in this Agreement and in the exhibits and schedules hereto are solely for the
      purpose of reference, are not part of the agreement of the parties hereto,
      and
      shall not in any way affect the meaning or interpretation of this Agreement
      or
      any exhibit or schedule hereto. All references to days or months shall be deemed
      references to calendar days or months. All references to “$” shall be deemed
      references to United States dollars. Unless the context otherwise requires,
      any
      reference to an “Article,” a “Section,” an “Exhibit,” or a “Schedule” shall be
      deemed to refer to a section of this Agreement or an exhibit or schedule to
      this
      Agreement, as applicable. The words “hereof,” “herein” and “hereunder” and words
      of similar import referring to this Agreement refer to this Agreement as a
      whole
      and not to any particular provision of this Agreement. Whenever the words
“include,” “includes” or “including” are used in this Agreement, unless
      otherwise specifically provided, they shall be deemed to be followed by the
      words “without limitation.” This Agreement shall be construed without regard to
      any presumption or rule requiring construction or interpretation against the
      party drafting or causing the document to be drafted.




*Section
      10.07*  *Confidentiality.* Except
      as required by law or stock exchange or other regulation or in any proceeding
      to
      enforce the provisions of this Agreement, or as otherwise provided below, each
      party hereby agrees not to publicize or disclose to any third party (x) the
      terms or conditions of this Agreement, or any exhibit, schedule or appendix
      hereto or thereto, or any information, data, schedules, route information,
      fare
      schedules and rules shared between the parties during the course of performance
      under this Agreement, without the prior written consent of the other parties
      thereto, or (y) any confidential information or data, both oral and written,
      received from the other, whether pursuant to or in connection with this
      Agreement, and designated as such by the other without the prior written consent
      of the party providing such confidential information or data (except that a
      party may disclose such information to its third party consultants, advisors
      and
      representatives, in each case who are themselves bound to keep such information
      confidential). Each of party hereby agrees not to use any such confidential
      information or data of the other party other than in connection with performing
      their respective obligations or enforcing their respective rights under this
      Agreement, or as otherwise expressly permitted or contemplated by this
      Agreement. If either party is served with a subpoena or other process requiring
      the production or disclosure of any of such agreements or information, then
      the
      party receiving such subpoena or other process, before complying with such
      subpoena or other process, shall, unless expressly requested not to do so by
      a
      government agency issuing the subpoena or other process, immediately notify
      the
      other parties hereto of same and permit said other parties a reasonable period
      of time to intervene and contest disclosure or production. Upon termination
      of
      this Agreement, each party must return to each other any confidential
      information or data received from the other and designated as such by the party
      providing such confidential information or data which is still in the
      recipient's possession or control. Without limiting the foregoing, no party
      shall be prevented from disclosing the following terms of this Agreement: the
      number of aircraft subject hereto, the periods for which such aircraft are
      subject hereto, and any termination provisions contained herein. The provisions
      of this Section 10.07 shall
      survive the termination of this Agreement for a period of ten
      years.




*Section
      10.08*  *Arbitration*





*(a)*  *Agreement
      to Arbitrate* .
      Subject
      to the equitable remedies provided under Section
      10.11 ,
      any and
      all claims, demands, causes of action, disputes, controversies and other matters
      in question (all of which are referred to herein as “ Claims ”)
      arising out of or relating to this Agreement, shall be resolved by binding
      arbitration pursuant to the procedures set forth by the International Institute
      for Conflict Prevention and Resolution (the “ CPR ”).
      Each
      of the parties agrees that arbitration under this Section
      10.08 is the
      exclusive method for resolving any Claim and that it will not commence an action
      or proceeding based on a Claim hereunder, except to enforce the arbitrators'
      decisions as provided in this Section
      10.08 ,
      to
      compel any other party to participate in arbitration under this Section
      10.08. The
      governing law for any such action or proceeding shall be the law set forth
      in Section
      10.08(f) .





*(b)*  *Initiation
      of Arbitration* .
      If any
      Claim has not been resolved by mutual agreement on or before the 15 th day
      following the first notice of the Claim to or from a disputing party, then
      the
      arbitration may be initiated by one party by providing to the other party a
      written notice of arbitration specifying the Claim or Claims to be arbitrated.
      If a party refuses to honor its obligations to arbitrate under this provision,
      the other party may compel arbitration in either federal or state court in
      New
      York, New York and seek recovery of its attorneys' fees and court costs incurred
      if the arbitration is ordered to proceed.




*(c)*  *Place
      of Arbitration* .
      The
      arbitration proceeding shall be conducted in New York, New York, or some other
      location mutually agreed upon by the parties.




*(d)*  *Selection
      of Arbitrators* .
      The
      arbitration panel (the “ Panel ”)
      shall
      consist of three arbitrators who are qualified to hear the type of Claim at
      issue. They may be selected by agreement of the Parties within thirty days
      of
      the notice initiating the arbitration procedure, or from the date of any order
      compelling such arbitration to proceed. If the Parties fail to agree upon the
      designation of any or all the Panel, then the Parties shall request the
      assistance of the CPR. The Panel shall make all of its decisions by majority
      vote. Evident partiality on the part of an arbitrator exists only where the
      circumstances are such that a reasonable person would have to conclude there
      in
      fact existed actual bias, and a mere appearance or impression of bias will
      not
      constitute evident partiality or otherwise disqualify an arbitrator. The
      decision of the Panel will be binding and non-appealable, except as permitted
      under the Federal Arbitration Act.





*(e)*  *Choice
      of Law as to Procedural Matters* .
      The
      enforcement of this agreement to arbitrate, and all procedural aspects of the
      proceeding pursuant to this agreement to arbitrate, including but not limited
      to, the issues subject to arbitration (i.e., arbitrability), the scope of the
      arbitrable issues, and the rules governing the conduct of the arbitration,
      unless otherwise agreed by the Parties, shall be governed by and construed
      pursuant to the Federal Arbitration Act.




*(f)*  *Choice
      of Law as to Substantive Claims* .
      In
      deciding the substance of the parties' Claims, the arbitrators shall apply
      the
      substantive laws of the State of New York (excluding New York choice-of-law
      principles that might call for the application of the law of another
      jurisdiction).




*(g)*  *Procedure* .
      It is
      contemplated that the arbitration proceeding will be self-administered by the
      parties and conducted in accordance with procedures jointly determined by the
      Panel and the Parties; *provided* ,
      however, that if either or both Parties believes the process will be enhanced
      if
      it is administered by the CPR, then either or both Parties shall have the right
      to cause the process to become administered by the CPR and, thereafter, the
      arbitration shall be conducted, where applicable or appropriate, pursuant to
      the
      administration of the CPR. In determining the extent of discovery, the number
      and length of depositions, and all other pre-hearing matters, the Panel shall
      endeavor to the extent possible to streamline the proceedings and minimize
      the
      time and cost of the proceedings.




*(h)*  *Final
      Hearing* .
      The
      final hearing shall be conducted within 120 days of the selection of the entire
      Panel. The final hearing shall not exceed ten business days, with each party
      to
      be granted one-half of the allocated time to present its case to the
      arbitrators, unless otherwise agreed by the Parties.




*(i)*  *Damages* .
      Only
      actual damages may be awarded. It is expressly agreed that the Panel shall
      have
      no authority to award treble, exemplary or punitive damages of any type under
      any circumstances regardless of whether such damages may be available under
      the
      applicable law.




*(j)*  *Decision
      of the Arbitration* .
      The
      Panel shall render its final decision and award in writing within 20 days of
      the
      completion of the final hearing completely resolving all of the Claims that
      are
      the subject of the arbitration proceeding. The Panel shall certify in its
      decision that no part of its award includes any amount for treble, exemplary
      or
      punitive damages. The Panel's decision and award shall be final and
      non-appealable to the maximum extent permitted by law. Any and all of the
      Panel's orders and decisions will be enforceable in, and judgment upon any
      award
      rendered in the arbitration proceeding may be confirmed and entered by, any
      federal or state court in New York, New York having jurisdiction.




*(k)*  *Confidentiality* .
      All
      proceedings conducted hereunder and the decision and award of the Panel shall
      be
      kept confidential by the Panel and, except as required by law or stock exchange
      regulation or in any proceeding to enforce any decision or award by the Panel,
      by the Parties.




*Section
      10.09*  *Counterparts.* This
      Agreement may be executed in two or more counterparts, each of which shall
      be
      deemed an original, but all of which together shall constitute one and the
      same
      instrument. The Agreement may be executed by facsimile signature.




*Section
      10.10*  *Severability.* Any
      provision of this Agreement which is prohibited or unenforceable in any
      jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
      such prohibition or unenforceability without invalidating the remaining
      provisions hereof. Any such prohibition or unenforceability in any jurisdiction
      shall not invalidate or render unenforceable such provision in any other
      jurisdiction.








*Section
      10.11*  *Equitable
      Remedies; Certain Liquidated Damages*




*(a)*  *Equitable
      Remedies* .
      Each
      party acknowledges and agrees that, under certain circumstances, the breach
      by a
      party of a term or provision of this Agreement will materially and irreparably
      harm the other party, that money damages will accordingly not be an adequate
      remedy for such breach and that the non-defaulting party, in its sole discretion
      and in addition to its rights under this Agreement and any other remedies it
      may
      have at law or in equity, may apply to any court of law or equity of competent
      jurisdiction (without posting any bond or deposit) for specific performance
      and/or other injunctive relief in order to enforce or prevent any breach of
      the
      provisions of this Agreement.




*(b)*  *Certain
      Liquidated Damages* .
      RAI
      will update from time to time Exhibit
      B to
      reflect the exact in-service week and in-service day that each of the TBD
      aircraft appearing on Exhibit
      B is
      known, with notification to Frontier as to such week being no later than
      [ *  ]
      in
      advance of the in-service week and the notification as to such date being no
      later than [*] in advance of the in-service date. RAI will deliver such amended Exhibit
      B to
      Frontier as soon as possible. If RAI shall fail to provide a Covered Aircraft
      (such Covered Aircraft being referred to as a “Delayed Aircraft”) on the
      applicable in-service day reflected on the amended Exhibit
      B, or, if no inservice date has been specified, the last day of the applicable
      scheduled inservice week, or, if no inservice week has been designated, the
      last
      day of the inservice month (in each case, the “Anticipated Service
      Date ”),
      RAI
      will pay to Frontier liquidated damages in an amount equal to [ *  ]
      per
      each day between the Anticipated Service Date and the actual in-service date
      of
      such aircraft (or, if applicable, the date of any election by Frontier to remove
      the aircraft, as provided below), *provided
      that* ,
      in the
      event such inservice delay is due to circumstances beyond the control of RAI
      and
      RAI provides prior notice (the “ Delay
      Notice ”)
      of
      such delay, such liquidated damages shall not in any event exceed (x) [*] if
      the
      Delay Notice is provided to Frontier no fewer than [*] prior to the Anticipated
      Service Date for the Delayed Aircraft, or (y) if such notice is delivered fewer
      than [*] prior to the Anticipated Service Date for the Delayed Aircraft, (i)
      [*]
      plus (ii) [*] times the difference between [*] minus the number of days between
      the date of such notice and the Anticipated Service Date for the Delayed
      Aircraft, and *provided
      further* ,
      if the
      revised delivery date for the Delayed Aircraft indicated in the Delay Notice
      (or
      in any subsequent notice as a result of subsequent delays), is more than [*]
      beyond the Anticipated Service Date, Frontier will have the right, to be
      exercised within five Business Days of receipt of such notice (or subsequent
      notice), to elect to remove the Delayed Aircraft from the terms of this
      Agreement. Should Frontier elect to remove the Delayed Aircraft from the terms
      of this Agreement pursuant to this Section
      10.11(b) ,
      (x) if
      such removal occurs prior to the Anticipated Service Date, no liquidated damages
      shall be payable by RAI, and (y) if such removal occurs after the Anticipated
      Service Date as a result of any such subsequent notice, the liquidated damages
      described herein will be calculated based on the number of days between the
      Anticipated Service Date and the date of Frontier’s election to remove such
      aircraft from this Agreement.





The
      parties agree that the damages to be suffered by Frontier in connection with
      RAI's failure to deliver an aircraft on an Anticipated Service Date shall be
      difficult to calculate, and that the foregoing liquidated damages are a good
      faith estimate of such damages, and that such liquidated damages are not
      intended to be a penalty. The parties further agree that the foregoing
      liquidated damages shall be Frontier's sole and exclusive remedies against
      RAI
      for any damages suffered solely as a result of RAI's failure to deliver an
      aircraft on an Anticipated Service Date as described above.


*(c)*  *Other
      Limitations on Seeking Damages* .
      Neither
      the right of any party to terminate this Agreement, nor the exercise of such
      right, shall constitute a limitation on such party's right to seek damages
      or
      such other legal redress to which such party may otherwise be
      entitled; *provided* that,
      absent the occurrence of another breach of this Agreement by RAI, Frontier
      shall
      not be entitled to seek damages solely for the occurrence of (i) an event of
      Cause of the type described in clause
      (iii) or clause
      (iv) of the
      definition thereof, (ii) a material breach of the type described in clause
      (ii) of Section
      8.02(b) ,
      or
      (iii) a termination pursuant to Section
      5.03 .




*Section
      10.12*  *Relationship
      of Parties.* Nothing
      in this Agreement shall be interpreted or construed as establishing between
      the
      parties a partnership, joint venture or other similar arrangement.




*Section
      10.13*  *Entire
      Agreement; No Third Party Beneficiaries.* This
      Agreement (including the exhibits and schedules hereto) are intended by the
      parties as a complete statement of the entire agreement and understanding of
      the
      parties with respect to the subject matter hereof and all matters between the
      parties related to the subject matter herein or therein set forth. This
      Agreement is made among, and for the benefit of, the parties hereto, and the
      parties do not intend to create any third-party beneficiaries hereby, and no
      other Person shall have any rights arising under, or interests in or to, this
      Agreement.




*Section
      10.14*  *Governing
      Law.* Except
      with respect to matters referenced in Section 10.08(e) (which
      shall be governed by and construed pursuant to the Federal Arbitration Act),
      this Agreement shall be governed by and construed in accordance with the laws
      of
      the State of New York (excluding New York choice-of-law principles that might
      call for the application of the law of another jurisdiction) as to all matters,
      including matters of validity, construction, effect, performance and remedies.
      Except as otherwise provided in Section
      10.08(e) ,
      any
      action arising out of this Agreement or the rights and duties of the parties
      arising hereunder may be brought, if at all, only in the state or federal courts
      located in the City and County of New York, New York.




*Section
      10.15*  *Right of Set-Off.* If any
      party hereto shall be in default hereunder to any other party, then in any
      such
      case the non-defaulting party shall be entitled to set off from any payment
      owed
      by such non-defaulting party to the defaulting party hereunder any amount owed
      by the defaulting party to the non-defaulting party thereunder; *provided* that
      contemporaneously with any such set-off, the non-defaulting party shall give
      written notice of such action to the defaulting party; *provided further* that the
      failure to give such notice shall not affect the validity of the set-off. It
      is
      specifically agreed that (i) for purposes of the set-off by any non-defaulting
      party, mutuality shall be deemed to exist among the parties; (ii) reciprocity
      among the parties exists with respect to their relative rights and obligations
      in respect of any such set-off; and (iii) the right of set-off is given as
      additional security to induce the parties to enter into the transactions
      contemplated hereby. Upon completion of any such set-off, the obligation of
      the
      defaulting party to the non-defaulting party shall be extinguished to the extent
      of the amount so set-off. Each party hereto further waives any right to assert
      as a defense to any attempted set-off the requirements of liquidation or
      mutuality. This set-off provision shall be without prejudice, and in addition,
      to any right of set-off, combination of accounts, lien or other right to which
      any non-defaulting party is at any time otherwise entitled (either by operation
      of law, contract or otherwise), including without limitation pursuant to Section
      3.06(b)(ii) hereof.




*Section
      10.16*  *Cooperation
      with Respect to Reporting.* Each of
      the parties hereto agrees to use its commercially reasonable efforts to
      cooperate with each other party in providing necessary data, to the extent
      in
      the possession of the first party, required by such other party in order to
      meet
      any reporting requirements to, or otherwise in connection with any filing with
      or provision of information to be made to, any regulatory agency or other
      governmental authority.

      10.17*  *Extension
      of Term.* Frontier may extend the Term of this Agreement for up to two extension periods
      by delivering to RAI written notice on such extension no less than 365 days
      prior to the end of the then existing Term. Any extension shall be for no less
      than three years.

*Section
      10.18*  *Life Limited Parts* .


Frontier
      and RAI shall each cooperate with one another in order to manage and minimize
      engine life limited parts (“ LLP ”)
      expenses for Covered Aircraft. To that end, RAI shall provide annual projections
      of LLP requirements and supplemental notice of specific engine maintenance
      events which require LLP replacement as they are scheduled. Frontier may, at
      its
      option and with RAI's consent (which consent shall not be unreasonably withheld)
      provide or arrange the provision of used serviceable LLPs that otherwise meet
      RAI's specifications and reasonable minimum cycle-remaining requirements, to
      be
      incorporated into a Covered Aircraft. In connection with the withdrawal of
      any
      Covered Aircraft from the capacity purchase provisions of this Agreement
      (whether at the end of such aircraft's scheduled term or otherwise), Frontier
      shall pay RAI for the pro-rata cost (based on useful life and using the
      then-current catalogue price for LLPs) of all LLPs consumed for all Scheduled
      Flights by such Covered Aircraft under this Agreement, and RAI shall pay
      Frontier for the pro-rata cost (based on useful life and using the then-current
      catalogue price for LLPs) of all LLPs provided by Frontier and incorporated
      into
      such Covered Aircraft pursuant to the previous sentence and not consumed for
      any
      Scheduled Flights under this Agreement.

      hereunder.





(c)  The
      guarantee by RAI Holdings in this Section 10.19 shall continue to be effective,

                personal,
                non-transferable, royalty-free right and license to adopt and use
                the

a.
                Frontier shall at all times remain the owner of the Frontier Marks
                and any
                registrations thereof and RAI's use of any Frontier Marks shall clearly
                identify Frontier as the owner of such marks (to the extent practical)
                to
                protect Frontier's interest therein. All use by RAI of the Frontier
                Marks

                Agreement.





b.

                of
                Frontier’s reasonable request to take any and all actions necessary to
                protect and preserve Frontier’s ownership of the Frontier
                Marks.





4.
            Use
                of the Frontier Marks.





a.
                RAI shall use the Frontier Marks only as authorized herein by Frontier
                and
                in accordance with such standards of quality as Frontier may
                establish.





b.
                RAI shall use the Frontier Marks on all Covered Aircraft (other than
                the
                Spare Aircraft) and all facilities, equipment and printed materials
                used
                in connection with the Regional Airline
                Services.





c.
                RAI shall not use the Frontier Marks for any purpose other than as
                set
                forth in thisExhibit C,
                and specifically shall have no right to use the Frontier Marks on
                or in
                any aircraft other than Covered Aircraft or in connection with any
                other
                operations of RAI.





d.
                Frontier shall have exclusive control over the use and display of
                the
                Frontier Marks, and may change the Frontier Marks at any time and
                from
                time to time, in which case RAI shall as soon as practicable make
                such
                changes as are requested by Frontier to incorporate the new Frontier
                Marks;*provided*that Frontier shall either pay directly the reasonable costs of making
                such changes or shall promptly reimburse RAI for its reasonable expenses
                incurred in making such changes.





e.
                Nothing shall abridge Frontier's right to use and/or to license the
                Frontier Marks, and Frontier reserves the right to the continued
                use of
                all the Frontier Marks, to license such other uses of the Frontier
                Marks
                and to enter into such agreements with other carriers providing for
                arrangements similar to those with RAI as Frontier may desire. No
                term or
                provision of this Agreement shall be construed to preclude the use
                of the
                Frontier Marks by other persons or for similar or other uses not
                covered
                by this Agreement.





5.
            Frontier-Controlled
                Litigation.
                Frontier at its sole expense shall take all steps that in its opinion
                and
                sole discretion are necessary and desirable to protect the Frontier
                Marks
                against any infringement or dilution. RAI agrees to cooperate fully
                with
                Frontier in the defense and protection of the Frontier Marks as reasonably
                requested by Frontier. RAI shall report to Frontier any infringement
                or
                imitation of, or challenge to, the Frontier Mark, immediately upon
                becoming aware of same. RAI shall not be entitled to bring, or compel
                Frontier to bring, an action or other legal proceedings on account
                of any
                infringements, imitations, or challenges to any element of the Frontier
                Marks without the written agreement of Frontier. Frontier shall not
                be
                liable for any loss, cost, damage or expense suffered or incurred
                by RAI
                because of the failure or inability to take or consent to the taking
                of
                any action on account of any such infringements, imitations or challenges
                or because of the failure of any such action or proceeding. If Frontier
                shall commence any action or legal proceeding on account of such
                infringements, imitations or challenges, RAI agrees to provide all
                reasonable assistance requested by Frontier in preparing for and
                prosecuting the same.





6.
            Revocation
                of License.
                Frontier shall have the right to cancel the license provided herein
                in
                whole or in part at any time and for any reason, in which event all
                terminated rights to use the Frontier Marks provided RAI herein shall
                revert to Frontier and the Frontier Marks shall not be used by RAI
                in
                connection with any operations of RAI. The following provisions shall
                apply to the termination of the license provided herein: in the case
                of a
                termination of the license to use the Frontier Marks, RAI shall cease
                all
                use of the Frontier Marks with respect to each Covered Aircraft within
                30
                days of such aircraft being withdrawn from the capacity purchase
                provisions of the Agreement, and shall cease all use of the Frontier
                Marks
                in all other respects within 30 days of last Covered Aircraft being
                withdrawn from this Agreement. Within such specified period, RAI
                shall
                cease all use of such other Frontier Marks, and shall change its
                facilities, equipment, uniforms and supplies to avoid any customer
                confusion or the appearance that RAI is continuing to have an operating
                relationship with Frontier, and RAI shall not thereafter make use
                of any
                word, words, term, design, name or mark confusingly similar to the
                Frontier Marks or take actions that otherwise may infringe the Frontier
                Marks.

*Base
      and Incentive Compensation* .




1.
            *Base
                Compensation*.
                Frontier will pay to RAI, in respect of the Covered Aircraft, the
                rates
                set for on Appendix 1 to this Exhibit D for each calendar month,
                times,
                the applicable Unit of Measure, times, in each case where the rate
                category is indicated as being “Subject to Margin” on Appendix 1, a margin
                of [*]
                (the “Margin”). Rates indicated as “Subject to Escalation on Appendix 1 to
                this Exhibit D will be adjusted in accordance with Section 3.02 of
                this
                Agreement.





2.
            *Pre-Bill
                Invoiced Amount*.
                The Invoiced Amount calculated in accordance with Section 3.06 (a)
                of the
                Agreement will be calculated by using the data from the Final Monthly
                Schedule and the Operational Assumptions for any given month as
                follows:


a.  the
      Invoiced Amount for each of the Fixed Cost cost elements will be calculated
      by
      multiplying (i) the Rate, times (ii) the Unit of Measure (as set forth in the
      Final Monthly Schedule and the Operational Assumptions for the month), times
      (iii) the Margin, where “W/A A/C” is the weighted average number of Covered
      Aircraft for the month and “Days” is the number of calendar days in the month.
      The Rate for each Fixed Cost element will not change during the Term except
      for
      the annual adjustment pursuant to Section 3.02 of the Agreement for those
      elements noted as “Subject to Escalation”; plus





b.  the
      Invoiced Amount for each of the Variable Cost elements will be calculated by
      multiplying (i) the Rate, times (ii) the Unit of Measure (as set forth in the
      Final Monthly Schedule and the Operational Assumptions for the month), times
      (iii) the Margin, times (iv) (other than those determined by using the “W/A A/C”
Unit of Measure) the Completion Factor Target Threshold percentage as in effect
      at the time of calculation, where “Blk Hrs” are the block hours estimated to be
      flown by the Covered Aircraft for the month, “W/A A/C” is the weighted average
      number of Covered Aircraft for the month, “Departures” is the number of
      departures estimated to be made by the Covered Aircraft during the month, “Flt
      Hrs” are the flight hours estimated to be flown by the Covered Aircraft for the
      month, “Pax” is the number of passengers estimated to be transported by the
      Covered Aircraft during the month, and “1000 RPMS” is the estimated revenue
      passenger miles flown by the Covered Aircraft during the month divided by 1,000.
      The Rate for each Variable Cost element will not change during the Term except
      for (i) the annual adjustment pursuant to Section 3.02 of the Agreement for
      those elements noted as “Subject to Escalation, and (ii) those elements noted as
      subject to “Periodic Adjustment” will be adjusted based on the actual costs of
the related insurance premiums paid by RAI, taking into account any increases
      or
      reductions in those premiums due to end of the coverage year calculations based
      on RAI’s operational statistics.





3.
            *Reconciled
                Costs*.
                The Fixed Cost elements calculated by using the “W/A A/C” Unit of Measure,
                and the Variable Cost elements will be reconciled pursuant to Section
                3.06
                (b) of the Agreement by calculating the difference between the Invoiced
                Amount for such elements and the amount due for such elements based
                on the
                Rate for each Variable Cost element times the actual Unit of Measure
                for
                the month.





4.
            *Pass-Thru
                Costs*.
                Frontier will reimburse RAI for each Pass-Thru Cost element in accordance
                with Section 3.06 (c) of the Agreement. Pass-Thru Costs are actual
                costs
                incurred and are not subject to Margin, Escalation or Periodic
                Adjustment.





5.
            *Incentive
                Compensation*.
                With respect to each calendar month, incentive compensation shall
                be
                calculated as follows:

                offset
                (represented by a payment by RAI to Frontier), in each case in respect
                of
                on-time performance, as determined pursuant toAppendix 2to

**Appendix
      2 to Exhibit D**




**Incentive
      Bonuses/Rebates**




1.  *On
      Time Bonus/Rebate* :
      The
      bonus or rebate/offset, as the case may be, for on-time performance shall be
      determined as follows:




Beginning
      each month or partial month after the 12 th Covered
      Aircraft is placed in service, the percentage of RAI’s Controllable arrivals
      within [ *  ]
      minutes
      will be measured using ACARS data for each completed Scheduled Flight as soon
      as
      practicable following the end of each calendar month of operation. A flight
      cancellation will not also be counted as a delayed flight. The Target Threshold
      is for [*]of all Scheduled Flights to arrive within [*] minutes of scheduled
      arrival. The Bonus Threshold is [*]. The Penalty Threshold is [*]and the Default
      Threshold is [*]. Should RAI fall below the Penalty Threshold for Controllable
      arrivals within [*] minutes, RAI shall pay Frontier a minimum penalty of [*]
      plus and an additional [*] per full percentage point below the Penalty
      Threshold. Should RAI’s Controllable arrivals within [*] minutes be between the
      Penalty Threshold and the Bonus Threshold, there shall be no payment due to
      or
      from either party. In the event that RAI meets or exceeds the Bonus Threshold
      for Controllable arrivals within [*] minutes, Frontier shall pay to RAI a
      minimum bonus payment of [*] plus an additional [*] per full percentage point
      above the Bonus Threshold.





2.  *Completion
      Factor Bonus/Rebate* :
      The
      bonus or rebate/offset, as the case may be, for completion factor shall be
      determined as follows:





Beginning
      each month or partial month after the 12 th Covered
      Aircraft is place in service, the percentage of RAI’s Controllable Completion
      Factor Percentage will be measured for each Scheduled Flight as soon as
      practicable following the end of each calendar month of operation. The Target
      Threshold is for [*] of all Scheduled Flights to be completed. The Bonus
      Threshold is [*]. The Penalty Threshold is [*]and the Default Threshold is
      [*].
      Should RAI fall below the Penalty Threshold for Controllable Completion Factor
      Percentage in any month, RAI shall pay Frontier, for each percentage point
      (rounded to the next highest full percentage in all cases) below the Penalty
      Threshold, a penalty of [*] for the first month, [*] for the second consecutive
      month, [*] for the third consecutive month, and [*] for the fourth consecutive
      month and each consecutive month thereafter that the Penalty Threshold is not
      met. Should RAI’s Controllable Completion Factor Percentage be between the
      Penalty Threshold and the Bonus Threshold in any month, there shall be no
      payments due to or from either party. In the event RAI meets or exceeds the
      Bonus Threshold for Controllable Completion Factor Percentage in any month,
      Frontier will pay RAI a bonus of [*].





3. *Bonus/Penalty
      Payment Terms and Definitions* .





a.  “Controllable”
      means factors other than those that are beyond RAI’s direct control, including,
      without limitation, weather, natural disasters, air traffic control, ground
      stops, taxi and parking delays, lightening strikes or bird strikes, delays
      caused by or requested by Frontier personnel, including aircraft ground
      damage.





b.  Frontier
      will be responsible for coding all delays and cancellations. When aircraft
      are
      scheduled for heavy maintenance, Frontier will determine, in its sole
      discretion, whether to reduce the flight schedule or use the spare aircraft
      to
      maintain schedule integrity. Should Frontier decide to use the spare aircraft
      to
      replace aircraft in scheduled heavy maintenance, incentive bonuses and rebates
      will be suspended until such time that the spare is removed from scheduled
      service to act once again as a spare or the out of service aircraft is returned
      to service, either as a scheduled aircraft or a spare aircraft.





c.  Any
      final
      settlement for bonuses or penalties will occur within 30 days after the end
      of
      each performance period. If any matters relating to the measurement or
      calculation of any penalties remain in dispute at the end of the 30 day period,
      Frontier will be entitled to set off the penalty amount it believes due against
      the next monthly payment due RAI, and will refund any excess over the final
      determined penalty within 5 business days’ of the parties reaching agreement on
      the measurement and calculation. If any matters relating to the calculation
      of
      bonuses remain in dispute at the end of the initial 30 day period, at the time
      final agreement is reached between the parties regarding the amount of bonus
      due, Frontier will pay the bonus to RAI plus interest on the agreed amount
      at an
      annual rate of prime plus [ *  ]
      for
      each day from the initial date of calculation through the date of
      payment.

a.  RAI
      shall
      at all times remain the owner of the RAI Marks and any registrations thereof

      by
      Frontier of the RAI Marks shall inure to the benefit of RAI. Nothing in this
      Agreement shall give Frontier any right, title, or interest in the RAI Marks
      other than right to use the RAI Marks in accordance with the terms of this
      Agreement





b.  Frontier
      acknowledges RAI's ownership of the RAI Marks and further acknowledges the
      validity of the RAI Marks. Frontier agrees that it will not do anything that
      in
      any way infringes or abridges RAI's rights in the RAI Marks or directly or
      indirectly challenges the validity of the RAI Marks.





3.  Use
      of
      the RAI Marks .





a.  Frontier
      shall use the RAI Marks only as authorized herein by RAI and in accordance
      with
      such standards of quality as RAI may establish.





b.  Frontier

      or
      deleting marks from the list specified in this Exhibit
      F ),
      in
      which case Frontier shall as soon as practicable make such changes as are
      requested by RAI to utilize the new RAI Marks; *provided* that RAI
      shall either pay directly the reasonable costs of making such changes to the
      RAI
      Marks or shall promptly reimburse Frontier for its reasonable expenses incurred
      in making such changes.





e.  Nothing
      shall abridge RAI's right to use and/or to license the RAI Marks, and RAI

      the use of the RAI Marks by other persons or for other similar uses not covered
      by this Agreement.





4.  RAI-Controlled
      Litigation .
      RAI at
      its sole expense shall take all steps that in its opinion and sole discretion

      cost, damage or expense suffered or incurred by Frontier because of the failure
      or inability to take or consent to the taking of any action on account of any
      such infringements, imitations, challenges or because of the failure of any
      such
      action or proceeding. If RAI shall commence any action or legal proceeding
      on
      account of such infringements, imitations or challenges, Frontier agrees to
      provide all reasonable assistance requested by RAI in preparing for and
      prosecuting the same.

      not be used by Frontier in connection with any operations of Frontier. Frontier
      shall cease all use of the RAI Marks in all respects upon the last Covered
      Aircraft being withdrawn from this Agreement. Frontier shall not thereafter
      make
      use of any word, words, term, design, name or mark confusingly similar to the
      RAI Marks or take actions that otherwise may infringe the RAI
      Marks.

**EXHIBIT
      G**


**Reasonable
      Operating Constraints**





The
      schedules for the Covered Aircraft shall meet all of the following quarterly
      average requirements:





1. Minimum
      & Maximum Scheduling Parameters :





**Minimum**
            **Maximum**Scheduled
                Block Hours per Aircraft per day
            [*]
            [*]Scheduled
                Cycles per Aircraft per day
            [*]
            [*]











Note:
      the
      above minimum and maximum schedule parameters apply only to those Covered
      Aircraft in scheduled service, not to the Spare Aircraft.





2. Aircraft
      Maintenance and Crew Requirements .





Frontier
      agrees to take into consideration RAI’s operational requirements for overnight
      maintenance and crew productivity (including, where feasible, mid-day flights
      into RAI crew base cities for crew exchanges) and legality.





(a)
      Frontier shall use its best efforts to produce a Final Monthly Schedule in
      cooperation with RAI that meets the following location and minimum (block to
      block) hour requirements for overnight aircraft:





(i)
      one-quarter (but in no event fewer than one) of the scheduled Covered Aircraft
      will remain overnight at Denver International Airport for normal maintenance
      (the “Required Denver RON Aircraft”);





(ii)
      one-half (but in no event fewer than one and otherwise rounded down to the
      nearest whole number) of the Required Denver RON Aircraft will be scheduled
      to
      provide 9 hours of available maintenance time;





(iii)
      the
      remaining Required Denver RON Aircraft will in no event have fewer than 7 hours
      of available maintenance time;





(iv)
      at
      least one day per week, one of the Required Denver RON Aircraft will be
      scheduled to provide at least 14 hours of available maintenance time (block
      to
      block)





(b)
      On
      the first Business Day of each calendar quarter, RAI will provide Frontier
      a
      listing of all scheduled heavy maintenance for the next twelve month period
      for
      all Covered Aircraft, and will use commercially reasonable best efforts to
      complete all scheduled heavy maintenance on the Aircraft during the four
      shoulder months of April, May, September and October.





3. Maintenance
      Bases .





RAI
      will
      establish a crew base and a maintenance base for line and overnight aircraft
      maintenance work at Denver International Airport. The Denver maintenance base
      will be sufficient to perform intermediate maintenance checks, clear minimum
      equipment list and configuration deviation list items, and perform general
      maintenance, trouble shooting, and component removals and repairs. RAI will
      also
      advise Frontier of all other cities where RAI maintains line maintenance bases
      upon execution of this Agreement and any overnight time requirements related
      to
      RAI’s line maintenance obligations.





4. Crew
      Overnights .





The
      schedule may allow for single overnights, multiple overnights, staged, and
      continuous duty overnights of crews in outstations, provided, should Frontier
      schedule continuous duty overnights or staged crews, incremental hotel and
      per
      diem costs related to such continuous duty overnights or staged crews will
      be
      billed by RAI to Frontier in arrears as a Pass Thru costs not subject to margin.
      Frontier reserves the right to review RAI’s crew schedules to ensure efficient
      and economic crew scheduling and agrees to negotiate economic settlement with
      RAI for schedule changes that materially affect crew utilization or line
      maintenance requirements.





5. Charter
      Flights .





Frontier
      may schedule, price and sell Charter Flights using the Covered Aircraft,
      provided RAI receives 60 days’ advance notice of the tentative dates and times
      of such Charter Flights and the final dates are built into the Final Monthly
      Schedule. Frontier may also request RAI to consider ad hoc Charter Flights.
      Frontier agrees to compensate RAI for any additional operating costs of the
      Charter Flights, including but not limited to aircraft ferry costs and
      unproductive crew time, as such costs are provided to Frontier at the time
      Frontier provides notice to RAI of the Charter Flights, or sufficiently in
      advance of Frontier’s bid for the Charter Flight to allow such costs to be
      passed through to the charterer.
