ARTICLE 2. EXCLUSIVITY.

A.   With the exception of (i) aircraft operated or committed to be operated for
American Airlines ("AA"), America West Airlines ("HP") and US Airways ("US")
pursuant to (a) codeshare agreements in place as of the date hereof between
Operator and each such carrier (each such agreement, an "Existing Codeshare
Agreement," and such agreements, collectively, the "Existing Codeshare
Agreements," and such aircraft, collectively, the "Committed Aircraft"), or (b)
any amendment to or modification of a Existing Codeshare Agreement, including an
agreement with a successor to such carrier that assumes an Existing Codeshare
Agreement by operation of law, in each case that does not increase the number of
aircraft that is subject to such Existing Codeshare Agreement beyond the number
of Committed Aircraft and the Option Aircraft (as defined below) subject to the
Existing Codeshare Agreement prior to such amendment or modification (a
"Permitted Codeshare Amendment"), (ii) the following option aircraft allocated
to existing Chautauqua codeshare partners as follows: AA-20 options, HP-12
options and US-25 options (collectively, the "Option Aircraft"), (iii) subject
to the rights and restrictions set forth below in Section 2(D), any Committed
Aircraft and/or Option Aircraft

that need to be repositioned with another carrier due to the termination (on
whole or in part) or breach of an Existing Codeshare Agreement or a Permitted
Codeshare Amendment (the "Repositioned Aircraft" and together with the Committed
Aircraft and the Option Aircraft, the "Excluded Aircraft"), and (iv) any
Excluded Aircraft that are operated under a Reverse Codeshare Agreement (as
defined below), Operator agrees to list its flights only under Delta's code
during the Term of this Agreement (the "Delta Connection Flights"). For purposes
of this Agreement, a "Reverse Codeshare Agreement" is an agreement pursuant to
which Chautauqua operates Excluded Aircraft under the designator code of another
carrier or under Chautauqua's RP designator code and the other party to an
Existing Codeshare Agreement or a Permitted Codeshare Amendment remains
obligated to compensate Chautauqua with respect to flights operated under such
designator code.

B.   Operator must obtain prior written approval from Delta if it chooses to
enter into a code-sharing (or similar) arrangement with another carrier,
excluding, however (i) the Existing Codeshare Agreements with AA, HP or US (or
any successors to such carriers who assume an Existing Codeshare Agreement by
operation of law), (ii) the Permitted Codeshare Amendments, (iii) subject to the
rights and restrictions set forth below in Section 2(D), a code-sharing
arrangement that relates to the Repositioned Aircraft, and (iv) a Reverse
Codeshare Agreement. Notwithstanding anything herein to the contrary except as
provided in Section 2(D), any such new code-sharing arrangement shall strictly
prohibit Operator from operating any aircraft, other than Repositioned Aircraft
as set forth in Section 2(D), for the new code share partner into or out of [*]

C.   During the Term of this Agreement, Operator shall not operate any flights
under its own flight designator code into or out of [*] excluding flights
operated under a Reverse Codeshare Agreement.

D.   With respect to any Repositioned Aircraft, but subject to the rights of AA
under its existing Codeshare Agreement:

     (i)  prior to entering into an agreement with a third party to operate any
          such aircraft for another party or operating any such aircraft for
          itself, Operator shall first provide written notice to Delta offering
          the opportunity to purchase, lease, or codeshare (or any combination
          thereof) such aircraft on terms no less favorable as offered to any
          third party (the "Right of First Refusal for Repositioned Aircraft");
          and

     (ii) in the event that Delta does not exercise its Right of First Refusal
          for Repositioned Aircraft within 10 business days after receipt of
          notice thereof, Operator shall be prohibited during the remaining term
          of this Agreement from flying greater than [*] flights per day into
          each of [*] with the Repositioned Aircraft without Delta's prior
          written consent.

Costs and the Pass Through Costs (each as such term is defined below, and
collectively, the "Direct Costs") and 100% of the Other Reimbursable Costs
relating to all flights undertaken by Chautauqua in connection with the Delta
Connection Program using the Aircraft. In addition, in any month in which
Chautauqua achieves a completion rate for the Delta Connection Flights of at
least [*]% (or at least [*]% until such time as Chautauqua has taken delivery of
10 of the Aircraft plus 1 spare) Delta shall pay Chautauqua a mark-up of [*]
([*]%) of such Direct Costs incurred during such month (the "Mark-Up"), subject
to certain limitations set forth below.

(i)  The "Base Rate Costs" shall include all direct, cash operating costs,
(specifically excluding any prepayments except as expressly provided herein)
based upon the model attached hereto as EXHIBIT B and subject to the

          amount equivalent to a monthly rate of $[*] for each ERJ-145 Aircraft
          and $[*] for each ERJ-135 Aircraft. In the event that Chautauqua
          leases an Aircraft, the Aircraft Rent/Ownership Costs for such
          Aircraft shall be the amount payable by Chautauqua under the
          respective lease. In the event Chautauqua owns an Aircraft subject to
          debt financing, the Aircraft Rent/Ownership Costs for such Aircraft
          shall be the amount payable by Chautauqua as debt payments in respect
          of such Aircraft, calculated as if [*]% of the Aircraft purchase price
          was financed by such debt. In the event that the amounts financed
          under such lease or debt financing do not include Chautauqua's third
          party costs and expenses incurred in connection with the acquisition
          and financing of such Aircraft, the Aircraft Rent/Ownership costs
          shall include, in addition to the amount of such lease payments or
          debt payments, the additional costs that would have been reflected in
          the lease or debt service payments, under the terms of the respective
          lease or debt financing, [*]% of such costs and expenses, not to
          exceed [*]% of the purchase price of the respective Aircraft (the
          "Additional Financing Amount").

     (3)  FUEL EXPENSE - Chautauqua's actual Aircraft fuel expenses; provided,
          however, any Mark-Up of the Fuel Expense shall be capped at an amount
          equivalent to a $[*] per gallon fuel price.

(iii) The "Pass Through Costs" shall include the following variable costs for
which Delta shall bear the risk of price fluctuations, provided that such costs
shall be reconciled on a monthly basis to reflect the actual costs incurred by
Operator:

          value of the Aircraft.
     (9)  The cost of any Support Services (as defined below) and any ticketing
          services, in each case only if not provided by Delta at its own
          expense; and
     (10) All costs to change the livery of any Aircraft pursuant to any request
          by Delta.

B. OTHER REIMBURSABLE COSTS.

     Delta shall reimburse Chautauqua for one hundred percent (100%) of the
costs incurred for the following items, but it is expressly agreed that no
Mark-Up of such costs shall be paid by Delta:

          (1)  Any Federal Aviation Administration ("FAA") or Department of
               Transportation ("DOT") fines administered or levied against
               Operator due to an action or omission principally caused by Delta
               or an affiliate of Delta; and

          (2)  Start-Up Training Costs associated with operating the Aircraft;
               provided, however in no event shall Delta be required to
               reimburse Chautauqua in excess of $[*] in aggregate for such
               costs.

C. NON-REIMBURSABLE COSTS.

<Page>

each in connection with the operation of the Aircraft. For each month during the
Term of this Agreement that Chautauqua has a completion rate for its Delta
Connection Flights of [*]% or greater, Delta shall pay Chautauqua an additional
[*] ([*]%) Mark-Up of the Direct Costs relating to such month. In addition, for
each month during the Term of this Agreement that Chautauqua has an on-time
arrival rate (i.e. within 15 minutes of the scheduled arrival time) for its
Delta Connection Flights of [*]% or greater, Delta shall pay Chautauqua an
additional [*] ([*]%) Mark-Up of the Direct Costs relating to such month.

2.   SEMI-ANNUAL INCENTIVE COMPENSATION. In addition to the Base Compensation
and the Monthly Incentive Compensation, Chautauqua shall have the opportunity to
earn additional compensation (the "Semi-Annual Incentive Compensation") based
upon its performance in certain performance categories as set forth herein.
During each six-month period (measured from each January 1 through June 30 and
July 1 through December 31) during the Term of this Agreement, Delta shall pay
Chautauqua an additional [*] ([*]%) Mark-Up of the Direct Costs for each of the
following performance goals that Chautauqua achieves during the applicable
six-month period:

          (i)    a completion rate for its Delta Connection Flights of [*]
                 ([*]%) or greater;

          (ii)   an on-time arrival rate for its Delta Connection Flights of [*]
                 ([*]%) or greater; and

          (iii)  a baggage claim rate for its Delta Connection Flights of less
                 than [*] claims per thousand passengers.

C. ACCOUNTING PROVISIONS.

     Delta shall retain all revenues (passenger, cargo, mail or any other
revenue, including without limitation, any guaranteed or incentive payments from
airport, local or municipal authorities in connection with scheduling flights to
such airport or locality) in connection with the operation of the Delta
Connection Flights. Operator shall promptly forward to Delta all monies with
respect to all airline ticket sales, on-board sales, baggage charges, passenger
charges, cargo sales and all other revenue collected in connection with the
operation of the Aircraft (including credit card transactions).

     On the 5th, 10th, 15th and 20th day of each month (or if not a business
day, on the following business day) Delta will advance to Chautauqua twenty-five
percent (25%) of the estimated monthly Direct Costs and Mark-Up (collectively,
the "Base Compensation"). In computing the amount of the advance, Delta will use
the projected fuel costs, and Delta will estimate the anticipated number of
weekly block hours based on the greater of (i) the scheduled block hours of the
Aircraft and (ii) the Minimum Utilization Requirements.

     Not later than twenty-five (25) days following the end of each month, Delta
and Operator will reconcile the actual costs incurred by Chautauqua for the Base
Compensation (subject to the Minimum Utilization Requirements), with the
estimated payments made pursuant to the previous paragraph. The reconciliation
will include a comparison of Chautauqua's actual completion rate for such month
with the minimum completion rate required to achieve the Mark-Up pursuant to
Section 3(A) hereof, any applicable Monthly Incentive Compensation based on
Chautauqua's actual

                                      - 6 -

<Page>

completion rate and on-time arrival rate for the applicable month, and in the
event such month is the end of a Semi-Annual Incentive Compensation measuring
period, will also include any applicable Semi-Annual Incentive Compensation that
may be due based upon Operator's performance during such period. Within two (2)
business days of completing such reconciliation, Delta or Operator, as the case
may be, shall wire transfer to an account designated by the other party, monies
equal to the reconciled amount.

     Notwithstanding anything herein to the contrary, in the event Chautauqua is
unable to operate any of the Aircraft, or any of the Delta Connection Flights,
due to a strike, labor dispute, work stoppage or similar event, provided in each
such case that such event is substantially within the control of, or caused by,
some action or inaction of Operator or relates to the Aircraft, Delta shall not
be obligated to pay Chautauqua any Base Compensation, incentive compensation, or
other amounts, in connection with such non-operated Aircraft and Delta
Connection Flights. However, in the event Chautauqua is unable to operate any of
the Aircraft, or any of the Delta Connection Flights, due to a strike, labor
dispute, work stoppage, or similar event, that is substantially within the
control of, or caused by, some action or inaction of Delta, Delta shall be
obligated to pay Chautauqua Base Compensation based on the Minimum Utilization
Requirements, and Chautauqua's eligibility for any Monthly Incentive
Compensation or Semi-Annual Incentive Compensation shall be calculated without
regard to any cancellations, delays or complaints caused by or relating to such
events. In the event Chautauqua is unable to operate any of the Aircraft, or any
of the Delta Connection Flights, due to an event that is not substantially
within the control of, or caused by, some action or inaction of either
Chautauqua or Delta, Delta shall be obligated to pay Chautauqua's fixed costs
(i.e. labeled as "Per Scheduled Aircraft Per Day" and "Fixed Per Day" on EXHIBIT
B attached hereto, as well as Aircraft Rent/Ownership Costs, Hull Insurance,
Property Taxes and Heavy Inspection Costs for inspections already in process
prior to any such event), but not any variable costs or Mark-Up, with respect to
such non-operated Aircraft and Delta Connection Flights during the period that
Chautauqua is unable to operate such Aircraft or the Delta Connection Flights.

D. REVIEW OF BASE AMOUNT AND SERVICE LEVELS.

     Operator shall maintain complete and accurate books and records to support
and document all revenues, costs and expenses related to the Aircraft hereunder,
in accordance with generally accepted accounting principles consistently applied
and in accordance with the accounting policies and procedures used by the
parties to develop the Direct Costs. Prior to the setting of the Annual Rate
Plan, Delta's in-house accounting staff and any independent accountants selected
by Delta shall be entitled, following reasonable notice to Operator, to review
and inspect Operator's books, records and costs incurred with respect to
services provided in prior periods, the service levels achieved, and the
determination of charges due pursuant to this Agreement for the purpose of (i)
prospectively adjusting the Base Rate Amount in connection with an annual review
pursuant to Section 3(E) hereof, or (ii) auditing Reimbursable Costs, Pass
Through Costs or Other Reimbursable Costs.. Any such review will be conducted
during regular business hours at Operator's offices.

E. COST CHANGES.

                                      - 7 -
<Page>

     Operator shall provide Delta an estimate of the next calendar year's
projected operating costs by September 30th of each year during the Term. Delta
will have the right to review and provide comments and suggestions to such
estimate, and such suggestions will be duly considered by Operator. Operator and
Delta hereby agree to meet promptly after each September 30th of each year
during the Term in order to review and revise the Direct Costs and corresponding
Base Compensation, as appropriate, for the subsequent calendar year utilizing
the same methodology as initially used to determine the Direct Costs and Base
Compensation (the "Annual Operating Plan") and will use commercially reasonable
efforts to reach agreement on an Annual Operating Plan for the next calendar
year prior to December 31 of each year. In the event that the parties are unable
to agree on any Annual Operating Plan, the parties further agree that (i) at the
request of either party, and at the expense of the requesting party, the parties
shall engage a mutually agreed independent consultant, to determine the
applicable Annual Operating Plan, [*], and (ii) if no new Annual Operating Plan
has been adopted by the beginning of the next calendar year, the existing Annual
Operating Plan shall be used on an interim basis to determine the Direct Costs
and Base Compensation, subject to reconciliation and retroactive adjustment upon
the adoption of a new Annual Operating Plan. Any determination by the
independent consultant shall be binding on and implemented by the parties. The
Annual Rate Plan will apply for all completed flights during the calendar year
applicable to such plan, and with respect to the Base Rate Costs only, Operator
will bear any risks of additional expenses not reflected therein. Operator shall
be entitled to payment of all Reimbursable Costs, Pass Through Costs and Other
Reimbursable Costs based on the actual amounts incurred without regard to the
Annual Rate Plan. Operator will use its commercially reasonable efforts
consistent with the business practices and policies used to develop the first
years Direct Cost model and with the prudent operation of its business to
minimize its costs to operate the Aircraft in accordance with this Agreement.
Operator and Delta each agree to notify the other as soon as reasonably
practicable of any anticipated or potentially substantial change of cost or
operational performance.

ARTICLE 4. AIRPORT RELATED AND TICKETING SERVICES.

A.   TICKETING SERVICES. Delta will provide its own primary airport ticketing
services, and, if applicable, Chautauqua will provide supplemental ticketing
services for Delta Connection Flights at Delta's airport ticketing locations and
will use Delta ticket stock for such purposes.

B.   SIGNAGE. Delta will design, provide and pay for appropriate airport and
other signage to reflect the Delta Connection and the relationship between
Chautauqua and Delta. The nature and type of such signage will be in the sole
discretion of Delta, subject to any airport, governmental or quasi-governmental
restrictions or requirements. Delta will be responsible for installing and
maintaining all such signage, but the parties will mutually determine which
party will obtain any necessary formal or informal approvals from appropriate
airport or other authorities to install such signage. The parties will fully
cooperate with each other in all endeavors relating to such signage and any
necessary approvals.

responsible for all undercharges and incorrect fares, rates and charges on
Traffic Documents issued by or for Chautauqua, and Delta may deduct from sums
due Operator or bill Operator for the amount of any such undercharges or
incorrect fares, rates and charges. The amount of such undercharges will be

affiliates') proprietary information. Any membership lists, labels, data, or
other compiled membership information supplied to Operator in any form and any

associated therewith. Any and all services provided by Delta to Operator shall
be at no cost to Operator and shall not be subject to any reimbursement or any
Mark-Up.

ARTICLE 9. AUTOMATION SERVICES. Delta agrees to provide Chautauqua the following
automation and related services for the Delta Connection Flights, and Chautauqua
agrees to participate in such services in the manner described below.

A. INTERNAL RESERVATIONS EQUIPMENT. Delta shall provide or arrange for the
provision to Chautauqua of an electronic reservations system (currently referred
to as "Deltamatic" but including any successor reservations system adopted by
Delta) and shall provide Chautauqua with: (i) the ability to access passenger
name records, (ii) automated ticketing capabilities, (iii) operational messaging
switching capabilities, (iv) the ability to update Delta Connection Flight
information, (v) the ability to distribute flight releases and weather packages,
and (vi) perform other reservations-related functions for the Delta Connection
Flights (Deltamatic and any successor system are hereinafter referred to as the
"Res System"). Delta reserves the right to modify the functionality of the Res
System at any time. Chautauqua will use the Res System made available by Delta
for the Delta Connection Flights only.

B. DELTA'S RIGHTS AND OBLIGATIONS.

     1.   Delta will install or cause to be installed the equipment requested by
Chautauqua at the locations set forth on EXHIBIT C to this Agreement and shall
provide Chautauqua connection to the Res System. The equipment described on
EXHIBIT C and any software installed on the Equipment at the time of its
delivery to Chautauqua are hereinafter referred to as the "Equipment."
Chautauqua understands and agrees that: (i) all Equipment shall remain the sole
property of Delta; (ii) Chautauqua shall not remove any identifying marks from
the Equipment; (iii) Chautauqua shall not subject the Equipment to any lien; and
(iv) Delta may enter Chautauqua's premises to remove the Equipment immediately
upon termination of this Agreement. EXHIBIT C may be amended from time to time
by mutual agreement of the parties to reflect the installation, removal or
relocation of Equipment.

     2.   Delta will provide initial and recurrent training to Chautauqua
training staff and other key designated personnel in the use of the Res System,
at Delta's training centers unless otherwise

                                     - 11 -
<Page>

agreed. Delta may remove from a training program any Chautauqua employee who is
not satisfactorily participating therein.

     3.   Delta will provide, or arrange to provide, all repairs and maintenance
services required for the Equipment and will use reasonable business efforts to
keep the Equipment and the Res System in good repair and condition. Chautauqua
will not perform or attempt to perform repairs or maintenance of any kind on the
Equipment without prior consultation with Delta and will promptly contact Delta
regarding the need for repairs or maintenance.

C.   CHAUTAUQUA'S RIGHTS AND OBLIGATIONS.


     1.   Chautauqua will not for any reason relocate or remove any of the
Equipment without Delta's prior written consent. Delta will pay all costs
associated with the installation, relocation or removal of Equipment.

     2.   Chautauqua will use the Equipment and the Res System in strict
conformity with the training and operating instructions provided by, or arranged
to be provided by, Delta. Without limiting the generality of the foregoing,
Chautauqua will not use the Res System to develop or publish any reservation,
ticketing, sales, cargo, tariff or other guide, to provide services not
authorized by this Agreement to third parties, to train persons other than
Chautauqua's employees in the use of the Equipment or the Res System, or for
other uses designated by Delta in writing as prohibited. Chautauqua may not
publish, disclose or otherwise make available to any third party the
compilations of air carrier service or fares obtained from the Res System;
provided, however, that Chautauqua may use specific air carrier service and fare
data for the benefit of its customers.

     3.   Chautauqua will ensure that its employees attend training sessions
related to the Res System, and it is Chautauqua's responsibility to insure that
each employee receives full and adequate training on the Res System.

     4.   Chautauqua will protect the Equipment from loss, damage or theft and
shall prevent its unauthorized use or improper operation. Chautauqua will make
no alterations to the Equipment and will return the Equipment to Delta upon the
termination of this Agreement in the same condition as received, excepting only
ordinary wear and tear in the normal course of Chautauqua's operations.
Chautauqua will obtain and maintain insurance for the Equipment against all
risks of damage and loss, including without limitation loss by fire, theft and
such other risks of loss as are customarily insured in a standard all-risk
policy. Such insurance shall also provide the following:

          (a)  Full replacement value coverage for the Equipment (subject to
policy deductibles);

          (b)  An endorsement naming Delta as the loss payee to the extent of
its interest in the Equipment; and

          (c)  An endorsement requiring the insurer to give Delta at least
thirty (30) days prior written notice of any intended cancellation, nonrenewal
or material change of coverage; provided that only ten (10) days prior written
notice of cancellation, nonrenewal or material change

                                     - 12 -
<Page>

of coverage need be given in the event that such cancellation, nonrenewal or
material change in coverage is caused solely by failure to make a premium
payment.

Upon request by Delta, Operator will promptly provide satisfactory evidence of
the insurance required pursuant to this Section 9(C)(4). Notwithstanding the
foregoing, Operator shall be liable to Delta for any loss or damage to the
Equipment, regardless of cause, occurring while the Equipment is in the
possession, custody or control of Operator.

     5.   Operator waives any proprietary rights that it may have with respect
to information entered into the Res System.

operations with respect to the Res System, (b) performing repairs or maintenance
on the Equipment, (c) installing, removing, replacing or relocating the
Equipment (unless otherwise permitted by this Agreement), or (d) training or

activities may not unreasonably interfere with Operator's business.

E.   LIMITATIONS ON LIABILITY. In addition to any other limitations on liability
set forth herein:

     1.   Delta is not responsible for errors or inaccuracies in the
availability records, fare quotes, or other information contained in the Res
System at any time, for any planned or unplanned interruptions, delays or
malfunctions in the operation of the Res System or the Equipment or for the
merchantability or fitness for a particular purpose of any of the data or
Equipment made available to Operator.

     2.   OPERATOR HEREBY WAIVES AND RELEASES DELTA AND ITS AFFILIATES AND THEIR
RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES AND AGENTS FROM ANY AND ALL
OBLIGATIONS AND LIABILITIES AND ALL RIGHTS, CLAIMS AND REMEDIES OF OPERATOR
AGAINST DELTA OR ITS AFFILIATES OR ANY OF THEIR RESPECTIVE DIRECTORS, OFFICERS,
EMPLOYEES OR AGENTS, EXPRESS OR IMPLIED, ARISING BY LAW OR OTHERWISE, DUE TO ANY
DEFECTS OR INTERRUPTIONS OF SERVICE IN, OR ERRORS OR MALFUNCTIONS BY, SOFTWARE,
THE EQUIPMENT OR THE RES SYSTEM, INCLUDING ALL LIABILITY, OBLIGATION, RIGHT,
CLAIM, OR REMEDY IN TORT, AND INCLUDING ALL LIABILITY, OBLIGATION, RIGHT, CLAIM
OR REMEDY FOR LOSS OF REVENUE OR PROFIT OR ANY OTHER DIRECT, INDIRECT,
INCIDENTAL, SPECIAL OR CONSEQUENTIAL DAMAGES. FURTHER, DELTA DISCLAIMS AND
OPERATOR HEREBY WAIVES ANY WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT
LIMITED TO ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR INTENDED USE RELATING
TO THE RES SYSTEM, THE EQUIPMENT, DATA, OR SERVICES FURNISHED HEREUNDER.

F.   PATENT AND COPYRIGHT INDEMNITY. Delta will defend or settle, at its own
expense, any action brought against Operator to the extent that it is based on a
claim that the Res System provided by Delta pursuant to this Agreement, in its
normal use, or any part thereof, infringes any U.S. copyright or patent; and
Delta will pay those costs, damages and attorney's fees finally awarded against

                                     - 13 -
<Page>

Operator in any such action attributable to any such claim, but such defense,
settlements and payments are conditioned on the following: (1) that Delta shall
be notified promptly in writing by Operator of any such claim; (2) that Delta
shall have sole control of the defense of any action on such claim and of all
negotiations for its settlement or compromise; (3) that Operator shall cooperate
with Delta in a reasonable way to facilitate the settlement or defense of such
claim, provided that Delta shall pay all of Operator's reasonable expenses
(including legal fees) in connection with any such cooperation requested by
Delta; and (4) should such Res System become, or in Delta's opinion be likely to
become, the subject of such claim of infringement, then Operator shall permit
Delta, at Delta's option and expense, either to (a) procure for Operator the
right to continue using the Res System, or (b) replace or modify the same so
that it becomes noninfringing and functionally equivalent, or (c) upon failure
of (a) and (b) above despite the reasonable efforts of Delta, accept immediate
termination of this Agreement as it relates to such system. This paragraph (F)
states the entire liability of Delta with respect to the infringement of
copyrights and patents by the Res System provided hereunder or the operation
thereof.

a number of complaints at [*] per 1,000 passengers flown or lower.

B.   In the event Operator fails to meet any of the standards set forth in
Section 10(A), Operator agrees to discuss with Delta such performance and
potential ways to improve such performance at Delta's request. Operator agrees
to develop in consultation with Delta a written remedial plan designed to
correct such failure and promptly implement any such written remedial plan.

nonbreaching party may immediately terminate this Agreement at its sole option.

D.   Notwithstanding the provisions of Section 11(A), in the event a Force
Majeure Event (as defined in Article 21) substantially prevents one party's
performance of its obligations pursuant to this Agreement, for a period of two
(2) or more consecutive months, the other party may terminate this Agreement
upon thirty (30) days prior written notice to the party affected by the Force
Majeure Event.

E.   Notwithstanding the provisions of Sections 11(A), (B), (C) and (D), Delta
shall have the right to terminate this Agreement immediately and at its sole

          (i)    Republic or Chautauqua agrees to merge into or with any entity,
agrees to be acquired by any entity, agrees to sell substantially all of its
assets or enters into a letter of intent, or similar document, to merge into or
with any entity, to be acquired by any entity, or to sell substantially all of
its assets unless (A) Republic or Chautauqua, as applicable, is the acquiring or
surviving entity, or (B) the ultimate beneficial ownership of the surviving
entity immediately following such transaction is substantially similar (i.e. at
least 75% common ownership) to the ultimate beneficial ownership of Republic or
Chautauqua as the case may be immediately prior to such transaction (each such
event that is not subject to such exceptions, a "Merger");

          (ii)   The acquisition by any individual, entity or group (within the
meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934

following such transaction is substantially similar (i.e. at least 75% common

case may be immediately prior to such transaction, (each such event that is not
subject to such exceptions, a "Change of Control");

          (iii)  Chautauqua's product quality with respect to its operation of
the Aircraft is not reasonably satisfactory to Delta thirty (30) days after
Delta has provided Chautauqua with written notice specifying Delta's
dissatisfaction with the product quality and proposing remedial measures to be
implemented by Chautauqua;

          (iv)   in the event Chautauqua fails to maintain a completion rate of
[*]% with respect to the Delta Connection Flights during any [*] period
commencing with the date that at least 11 Aircraft (10 Aircraft and 1 Spare)
have been scheduled to be placed into service in the Delta Connection Program;

          (v)    Chautauqua's failure to pass, in Delta's reasonable judgment, a
safety and codeshare audit to be conducted by Delta prior to the commencement of
any operation of any Delta Connection Flights; and

          (vi)   Chautauqua's level of safety is not reasonably satisfactory to
Delta; provided, however, in such event, this Agreement shall first be suspended
for up to thirty (30) days from the date that Delta provides written notice to
Chautauqua of its dissatisfaction, and then at the end of such up to 30-day
period, Chautauqua's level of safety is still not reasonably satisfactory to
Delta, Delta may immediately terminate this Agreement by delivery of written
notice to Chautauqua. In the event this Agreement is suspended under this
Section 11(E)(vi), Delta shall not be obligated to make any payments to
Chautauqua in respect of any services that would have been provided by
Chautauqua during the period of such suspension or to reimburse Chautauqua for
any costs or expenses incurred by Chautauqua during such period.

hereof, Delta may terminate this Agreement, with or without cause, in its sole
discretion, in whole or in part, on not less than one hundred eighty (180) days'
prior written notice to Operator; provided, however, that such notice shall not
be given prior to thirty-six (36) months after the 22nd Aircraft is scheduled to
be placed into service in the Delta Connection Program, and provided further,
that Delta may not initially reduce the number of Aircraft in service to a
number that is less than twelve (12) other than through a complete termination
of the Agreement. [*]

pursuant to Section 11(F) hereof, or in the event Operator terminates this
Agreement pursuant to Section 11(B), 11(C) or 11(D) hereof, Operator shall have

onerous than the terms that applied to Operator (with no assumption penalties,
fees or similar costs to Delta other than taxes, if any, and Delta's own fees
and expenses incurred to consummate such transfer or assumption) (the "Put
Right"). Operator shall have the right to exercise the Put Right by providing

Deadline, (b) Delta's receipt of written notice from Operator that Operator will
not exercise the Put Right with respect to any or all of the terminated
Aircraft, or (c) in the event Operator does not have a Put Right, the effective

the terminated Aircraft that are owned by Operator at Delta's option (I) to sell
the Aircraft for the Agreed Amount, or (II) to sublease the Aircraft to Delta on
the Sublease Terms, or (z) with respect to all or any of the terminated Aircraft
that are leased by Operator to assume the lease with respect to such Aircraft,
provided that any assumption by Delta of such lease must be on terms that are
the same or better than the terms that applied to Operator (with no assumption
penalties, fees or similar costs to Delta other than taxes, if any, and Delta's
own fees and expenses incurred to consummate such transfer or assumption) (the
"Call Right"). In connection with any leased Aircraft, Operator hereby covenants
and agrees that Operator shall obtain any and all third party consents,
including, without limitation, the lessors of the Aircraft, necessary to
effectuate the Put Right and the Call Right without penalty, fee or additional
cost (other than taxes, if any, and transaction fees and expenses) to Delta
simultaneously with the execution of any such lease.

L.   [*].

M.   In the event of any transfer of any of the Aircraft pursuant to Section

D.   OTHER THAN ANY WARRANTIES SPECIFICALLY CONTAINED IN THIS AGREEMENT, EACH
PARTY DISCLAIMS AND THE OTHER PARTY HEREBY WAIVES ANY WARRANTIES, EXPRESS OR
IMPLIED, ORAL OR WRITTEN, WITH RESPECT TO THIS AGREEMENT OR ITS PERFORMANCE OF
ITS OBLIGATIONS HEREUNDER INCLUDING, BUT NOT LIMITED TO, ANY WARRANTY OF
MERCHANTABILITY OR FITNESS FOR INTENDED USE RELATING TO ANY EQUIPMENT, DATA,
INFORMATION OR SERVICES FURNISHED HEREUNDER. EACH PARTY AGREES THAT THE OTHER
PARTY IS NOT LIABLE TO IT OR ANY OTHER PERSONS FOR CONSEQUENTIAL OR PUNITIVE

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

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 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 suffered by the Indemnified Party hereunder. Notwithstanding anything
contained in this Section 12(E) to the contrary, Republic, Chautauqua and Delta
will cooperate in the defense of any claim imposed jointly against them or as
the result of the conduct of the other.

          by Operator will not affect the coverage provided hereunder with
          respect to Delta, its affiliates, and their directors, officers,
          employees and agents; and (b) to provide that Operator's underwriters
          shall waive all subrogation rights arising out of this Agreement

          (A)(5), (A)(6), (A)(7) and (A)(8): (a) to provide that Delta, its

shall not be canceled, terminated or materially altered, changed or amended by
Operator's insurance underwriters until after thirty (30) days' written notice
to Delta, which thirty (30) days' notice shall commence to run from the date
such notice is actually received by Delta.

D.   Not later than the effective date of this Agreement, and from time to time

and are in full force and effect.

E.   In the event Operator fails to maintain in full force and effect any of

Article 14(A), Delta shall have the right (but not the obligation) to procure
and maintain such insurance or any part thereof on behalf of Operator. The cost
of such insurance shall be payable by Operator to Delta upon demand by Delta.
The procurement of such insurance or any part thereof by Delta does not
discharge or excuse Operator's obligation to comply with the provisions set out
herein. Operator agrees not to cancel, terminate or materially alter, change or
amend any of the policies until after providing thirty (30) days' advance
written notice to Delta of Operator's intent to so cancel, terminate or
materially alter, change or amend such policies of insurance, which thirty (30)

report and has no other obligations with respect to such claims, and Operator is
fully responsible for handling all adjustments, settlements, negotiations,
litigation and similar activities in any way related to or connected with such
claims.

G.   The parties hereby agree that from time to time during the term of this
Agreement Delta may require Operator to procure and maintain insurance coverages
in amounts in excess of the minimum amounts set forth in Article 14(A) should
the circumstances and conditions of Operator's operations under this Agreement
be deemed, in Delta's sole discretion, to require reasonable increases in any or
all of the foregoing minimum insurance coverages.

A.   Delta and Operator agree that, subject to the provisions of this Agreement,
Chautauqua will operate for the Delta Connection Flights exclusively as a Delta

     Subject to the rights of AA and AMR Corporation pursuant to its Existing
Codeshare Agreement (or any Permitted Codeshare Amendment of such Existing
Codeshare Agreement), and excluding any transaction (including without
limitation any lease, sale/leaseback, leveraged lease, single investor lease or
similar transaction) undertaken to finance or refinance the purchase or
acquisition of any Aircraft or Excluded Aircraft, if at any time during the Term
of this Agreement, Operator receives an offer, bid, inquiry or other expression
of interest ("Offer") to purchase, lease, sublease, encumber or otherwise
acquire any interest in, or to operate on

                                     - 24 -
<Page>

behalf of any third party, any aircraft owned or leased by Operator (the "ROFR
Aircraft"), which Offer Operator desires to accept, Operator will, within ten
(10) business days after the material terms and conditions of such Offer have
been determined, notify Delta in writing of such Offer and the material terms
and conditions thereof, including the time period for consummating such Offer
(the "Offer Notice"). Upon receipt of an Offer Notice, Delta will have fifteen
(15) days to either (i) exercise its right of first refusal by providing written
notice to Operator that it will consummate the transaction for or in connection
with the ROFR Aircraft set forth in the Offer (the "Offered Aircraft") on the
same terms and conditions that are set forth in the Offer Notice, or (ii) notify
Operator that it does not wish to exercise its right of first refusal (failure
to reply in such 15 day period shall be deemed to be an election by Delta not to
exercise its right of first refusal). In the event Delta elects to exercise its
right of first refusal, such election shall be binding and irrevocable and
Operator and Delta shall consummate the transaction contemplated in the Offer
Notice on the same terms and conditions that are set forth in the Offer Notice
within the time period set forth in the Offer Notice. If Delta elects not to
exercise its right of first refusal, Operator may consummate such transaction
with the third party or parties making the Offer. Notwithstanding anything to
the contrary herein, this Article 17 shall not be applicable to, and Operator
shall have no obligation to provide Delta with an Offer Notice in connection
with, (i) any Committed Aircraft, or (ii) any Option Aircraft; provided,
however, such Option Aircraft are converted into firm orders by the appropriate
designated carrier as set forth in Section 2(A) within the third anniversary of
the effective date of this Agreement.

ARTICLE 18. MOST FAVORED NATIONS.

A.   If at any time during the Term of this Agreement, Operator reaches an
agreement in principle with any third party with respect to any new, amended
and/or restated codesharing (or similar) relationship, other than a Permitted
Codeshare Amendment, utilizing ERJ 135LR or ERJ 145LR aircraft (the "Third Party
Agreement"), Operator must offer Delta, in writing, the right, on an all or
nothing basis, to modify and amend this Agreement to incorporate the terms and
conditions of such Third Party Agreement (the "MFN Offer"). The MFN Offer shall
include all the material terms and conditions of the Third Party Agreement.
Delta shall have thirty (30) days from receipt of the MFN Offer to elect whether
or not to accept such MFN Offer. Upon Delta electing to accept the MFN Offer,
the terms and conditions of such MFN Offer shall govern the Aircraft and this
Agreement shall be modified and amended as appropriate.

B.   The parties acknowledge and agree that the rights granted to Delta in
Section 18(A) above shall not apply to any Excluded Aircraft.

ARTICLE 19. COVENANTS OF OPERATOR. Operator or Republic, as appropriate, hereby
covenants and agrees that:

C.   In the event that any of the Aircraft are owned and debt financed by
Chautauqua, as soon as reasonably practicable, Chautauqua shall use commercially
reasonable efforts to convert any such debt financing into an operating lease
arrangement; provided any such lease (i) is financially more favorable than the
existing debt financing and (ii) shall be subject to the prior written approval
of Delta.

D.   Upon the addition of any and each aircraft to the original twenty-two (22)
Aircraft set forth on Exhibit A to be operated by Chautauqua pursuant to the
terms and conditions of this Agreement, and any amendment thereto, Republic
shall promptly issue to Delta a warrant to purchase 60,000 shares of Republic
Common Stock in the form attached hereto as EXHIBIT E.

ARTICLE 20. CONTRACT INTERPRETATION.

A.   This Agreement is subject to, and will be governed by and interpreted in
accordance with, the internal laws of the State of New York, excluding conflicts
of laws rules, and of the United States of America. Any action or proceeding
seeking to enforce any provision of, or based on any right arising out of, this
Agreement may only be brought in the courts of the State of Georgia, or, if it
has or can acquire jurisdiction, in the United States District Court for the
Northern District of Georgia, and each of the parties hereto irrevocably
consents to the exclusive jurisdiction of such courts (and of the appropriate
appellate courts) in any such action or proceeding and waives, to the fullest
extent permitted by law, any objection to venue laid therein. Process in any
action or proceeding referred to in the proceeding sentence may be served on any
party anywhere in the world. Each party further agrees to waive any right to a
trial by jury.

B.   The descriptive headings of the several articles and sections of this
Agreement are inserted for convenience only, confer no rights or obligations on
either party, and do not constitute a part of this Agreement.

C.   Time is of the essence in interpreting and performing this Agreement.

D.   This Agreement, together with the Equity Agreements, constitutes the entire
understanding between the parties with respect to the subject matter hereof, and
any other prior or contemporaneous agreements, whether written or oral, are
expressly superseded hereby.

E.   If any part of any provision of this Agreement shall be invalid or
unenforceable under applicable law, such part shall be ineffective to the extent
of such invalidity or unenforceability only, without in any way affecting the
remaining parts of such provision or the remaining provisions.

F.   This Agreement may be executed in any number of counterparts, each of which
shall be deemed to be an original and all of which, taken together, shall
constitute one and the same instrument.

due, each party will be relieved of its obligations under this Agreement in the
event, to the extent and for the period of time that performance is delayed or
prevented caused by any acts of God, acts of terrorism or hostilities, war,
strike, labor disputes, work stoppage, fire, act of government, court order, in
each case reasonably beyond the control of that party, including but not limited
to, non-delivery or delay in delivery of the Aircraft or delay in the completion
of required training of the Operator's employees by the Aircraft manufacturer or
delay in the receipt of any necessary government or regulatory approvals (each,
a "Force Majeure Event"). Each of the parties acknowledges that it may or may
not realize the full economic or other benefits that it expects to realize from
this Agreement and that any failure to realize any or all of such benefits shall
not constitute a Force Majeure Event.

ARTICLE 21A. NON-EXCLUSIVE LICENSE GRANTED.

A.   Operator will conduct all operations described herein under the service
mark "Delta Connection." Delta hereby grants to Operator a nonexclusive,
nontransferrable license to use certain trademarks, service marks, logos and
trade names that Delta owns or has the right to use, including, "Delta," "Delta
Connection," "SkyMiles," and the Delta widget design (collectively, the "Delta
Marks") in connection with the services to be rendered by Operator pursuant to
this Agreement; provided, however, that at any time during the Term of this
Agreement, Delta may alter, amend or revoke the license hereby granted and
require Operator's use of a new or different Delta Mark in connection with the
services provided hereunder as Delta may determine in its sole discretion.

B.   Operator hereby acknowledges Delta's right to use the Delta Marks, further
acknowledges the validity of the Delta Marks, and agrees that it will not do
anything in any way to infringe or abridge Delta's, or any of its affiliates',
rights in the Delta Marks or directly or indirectly to challenge the validity of
the Delta Marks.

C.   Operator shall not use any of the Delta Marks without Delta's prior written
consent.

D.   Nothing in this Agreement shall be construed to give Operator the exclusive
right to use any of the Delta Marks, or to abridge Delta's right to use or
license any of its trademarks, service marks, trade names or logos
(collectively, "Identification") and to license such other uses of such
Identification as Delta or its affiliates may desire.

E.   Should this Agreement be canceled or otherwise terminated for any reason as
set forth in Article 11 hereof, all right to use the Delta Marks shall revert to
Delta and shall not thereafter be used by Operator in any form or fashion.

F.   BRANDING.

     1. LIVERY. Each of the Aircraft shall be in the color scheme, including
exterior paint and interior upholstery and appointments ("Livery") of the Delta
Connection Livery, as provided by Delta to Chautauqua from time to time.

(collectively, the "Representatives"), at all times, maintain strict confidence
and secrecy in respect of all Confidential Information (as defined below) of the
other party (including its affiliates) received directly or indirectly as a

determines that it is required to disclose any Confidential Information of other
party (the "Affected Party") in order to comply with any applicable law or
government regulation, or under the terms of a subpoena or order issued by a
court or governmental body, it shall (a) notify the Affected Party immediately
of the existence, terms and circumstances surrounding such request, (b) consult
with the Affected Party on the advisability of taking legally available steps to
resist or narrow such request and (c) if any disclosure of Confidential
Information is required to prevent the Disclosing Party from being held in
contempt or subject to other legal penalty, furnish only such portion of the
Confidential Information as it is legally compelled to disclose and use
commercially reasonable efforts (at the cost of the party whose Confidential
Information is being protected) to obtain an order or other reliable assurance
that confidential treatment shall be accorded to the disclosed Confidential
Information. Each party agrees to transmit Confidential Information only to such
of its Representatives as required for the purpose of implementing and
administering this Agreement, and shall inform such Representatives of the
confidential nature of the Confidential Information and instruct such
Representatives to treat such Confidential Information in a manner consistent
with this Article 26.

     For purposes of this Agreement, "Confidential Information" shall mean
(a) all confidential or proprietary information of a party, including, without
limitation, trade secrets, information concerning past, present and future
research, development, business activities and affairs, finances, properties,
methods of operation, processes and systems, customer lists, customer
information (such as passenger name record or "PNR" data) and computer
procedures and access codes; and (b) the terms and conditions of this Agreement,
and any reports, invoices or other communications between the parties given in
connection with the negotiation or performance of this Agreement; and (c)
excludes (i) information already in a party's possession prior to its disclosure
by other party; (ii) information obtained from a third person or entity that is
not prohibited from transmitting such information to the receiving party as a
result of a contractual, legal or fiduciary obligation to the party whose
information is being disclosed; (iii) information that is or becomes generally
available to the public, other than as a result of

                                     - 30 -
<Page>

disclosure by a party in violation of this Agreement; or (iv) information that
has been or is independently acquired or developed by a party, or its affiliate,
without violating any of its obligations under this Agreement.

B.   Each party acknowledges and agrees that in the event of any breach of this
Article 26, the Affected Party shall be irreparably and immediately harmed and
could not be made whole by monetary damages. Accordingly, it is agreed that, in
addition to any other remedy at law or in equity, the Affected Party shall be
entitled to an injunction or injunctions (without the posting of any bond and
without proof of actual damages) to prevent breaches or threatened breaches of
this Article 26 and/or to compel specific performance of this Article 26.

C.   The confidential obligations of the parties under this Article 26 shall
survive the termination or expiration of this Agreement.

ARTICLE 27. ADDITIONAL DOCUMENTS. Simultaneously with the execution of this
Agreement, Republic shall provide to Delta the following securities, documents
and agreements (the "Equity Agreements"), each in form and substance reasonably
satisfactory to Delta and duly and validly executed and delivered by Republic:

     (i)    an IPO Warrant to purchase  1.5  million  shares of Republic  Common
            Stock;

     (ii)   a Private  Placement  Warrant  to  purchase  1.5  million  shares of
            Republic Common Stock at a price per share of $12.50;

FLEET HOUR AGREEMENTS

In accordance with the letter dated May 23rd from Rolls-Royce to Delta Air
Lines, reference CH-DL-052202 and the letter dated June 3rd reference
CH-DL-060302; Rolls-Royce is pleased to offer Chautauqua a [*] Fleet Hour
Agreement, from EIS of the first Aircraft, at the following Fleet Hour Agreement
rates.

The rates contained herein are predicated upon 22 Firm Aircraft and 30 Option

        the exception of time expired Life Limited Parts and Line Replaceable
        Units),
     -  All shop visit subcontract charges.

The Engine Shop Visit rate assumes use of normal take off rating (AT/O-1) for
[*] of all take offs, and use of normal climb and normal cruise ratings for all
flights. To the extent Chautauqua's usage of AT/O-1 differs from this
assumption, then the Shop Visit Rate will vary in accordance with the table in
Attachment C.

In the event of an early termination of the Fleet Hour Agreement, a
reconciliation will be performed in accordance with Article 12.3 to the Fleet
Hour Agreement between Rolls-Royce and Chautauqua dated March 23rd 2001.

ATTACHMENT C
AT/O-1 USAGE MATRIX

The Shop Visit rate assumes use of normal take off rating (AT/O-1) for [*]% of
all take offs, and use of normal climb and normal cruise ratings for all
flights. To the extent Chautauqua's usage of AT/O-1 differs from this
assumption, then the Shop Visit Rate will vary in accordance with the following
table:
