CODESHARE AGREEMENT

This CODESHARE AGREEMENT (this “Agreement”), dated as of September 1, 2011, is between United Air Lines, Inc. (“United”), a corporation organized under the laws of the State of Delaware, United States of America, having its principal place of business at 00 X Xxxxxx Xx, Xxxxxxx, XX 00000 (“UA”), and Great Lakes Aviation, Ltd. (“Great Lakes”), a company organized under the laws of Iowa, having its principal office at 0000 Xxxxxxx Xxxxxxx, Xxxxxxxx, Xxxxxxx 00000 (“ZK”).

In consideration of the mutual covenants and promises in this Agreement, United and Great Lakes hereby agree as follows:

1. DEFINITIONS

1.1 Terms with their initial letters capitalized shall have the meanings ascribed to them in Annex A of this Agreement or where they are elsewhere defined herein (including the Annexes hereto). Such ascribed meanings shall be equally applicable to both the singular and plural forms of such terms. United and Great Lakes may each be referred to as a “Party” and may collectively be referred to as the “Parties”.

1.2 The Parties agree that accepted industry procedures and agreements relating to the interlining of passengers and baggage, including those set forth in IATA Resolution 780 Interline Traffic Agreement – Passenger for all international carriage shall apply to the provision of air transport and the related transactions contemplated by this Agreement, except to the extent that they are inconsistent or conflict with the terms of this Agreement.

2. CODESHARE SERVICE

2.1 The Parties have designated certain flights on which United has placed its Code (each, a “Codeshared Flight”), which may include flights operated by their Affiliates, serving the city-pairs (each city-pair, a “Codeshared Route”) identified in writing by the Parties from time to time without formally amending this Agreement and benefit to be part of the Agreement. The initial list of Codeshared Routes on which the Parties and their Affiliates may codeshare is attached hereto as Annex B. Great Lakes shall provide to the Codeshared Passengers, at a minimum, the same standard of customer service as it provides to its own passengers traveling in the same class of service which standard shall, in any event, be reasonably in accordance with the standards of customer service reasonably established by United for the comparable class of service on its flights. Minimum customer service standards, general passenger service procedures, and policies for the Codeshared Flights, including baggage services, will be as agreed by the Parties.

2.2 The Parties shall use commercially reasonable efforts to coordinate their service schedules to maximize the convenience, and minimize the waiting time of passengers making connections between the Codeshared Flights and other flights operated by the Parties; provided, however, that neither Party is obligated to operate specific flights or service schedules and each Party retains the right to determine the service schedules of its own flights.

Page 4 of 35

2.3 The Parties may add Codeshared Flights, as may be mutually agreed, without formally amending this Agreement. Either Party may, in its sole discretion, discontinue Codeshared Flights without formally amending this agreement. Such changes shall be evidenced by United’s publishing such changes in the Airline Guides, CRSs or Reservations Systems. Great Lakes reserves the right to discontinue any specific route, flight number, equipment or schedule, and United reserves the right to remove its Code from any Codeshared Flight at any time. In the event of such discontinuation or removal, the Party so discontinuing or removing, as applicable, shall notify the other Party as soon as reasonably possible and such other Party shall cooperate in publishing the resulting changes to affected Codeshared Flights in the Airline Guides, CRSs, Reservations Systems, and other sources of airline schedule information.

2.4 Unless otherwise agreed by the Parties, in the event of any flight cancellation or other schedule irregularity, involuntary rerouting or denied boarding by Great Lakes with respect to a Codeshared Flight, Great Lakes shall:

(a) ensure that all passengers shall be handled in accordance with the same policies and procedures to avoid any discrimination against a Codeshared Passenger;

(b) at its own cost and expense (except to the extent such irregularity, involuntary rerouting or denied boarding is caused by United), accommodate and/or pay denied boarding compensation or otherwise compensate Codeshared Passengers, in the same manner as its own passengers; and

(c) notify United as agreed upon.

2.5 With respect to Codeshare Passengers for matters between the passenger and United, the Conditions of Carriage of United shall be deemed to govern the transportation of Codeshare Passengers on Codeshare Flights. As between the Carriers, the Conditions of Carriage of Great Lakes shall govern the transportation of Codeshare Passengers on Codeshare Flights. The Carriers will use commercially reasonable efforts to identify any material discrepancies between their respective Conditions of Carriage and use commercially reasonable efforts to develop procedures to minimize potential service inconvenience or disruption to Codeshare Passengers due to such discrepancies. For the avoidance of doubt, Each Carrier’s operations will be conducted in accordance with its own Conditions of Carriage and neither Carrier shall be obligated to change its Conditions of Carriage pursuant to this Agreement. Notwithstanding anything in this Section 2.6, the liability of the Parties to each other with respect to passenger claims shall be governed by Sections 18 and 19.

2.6 Great Lakes shall ensure that each Codeshared Flight operated by it shall be operated under its operating certificate. In the event that Great Lakes intends to substitute for a Codeshared Flight an aircraft that will be operated under the operating certificate of a third-party Great Lakes must provide United with prior written notice of its intention. Such notice shall be provided to United as soon as practicable after Great Lakes makes its decision regarding the aircraft substitution. United shall have the right, should it elect to do so, to (i) accommodate its passengers on the substitute aircraft, or (ii) remove its Code from the Codeshared Flight, and reaccommodate its Codeshared Passengers ticketed for travel on such Codeshared Flight to another flight. Great Lakes shall reimburse United for all costs of such reaccommodation, including (i) any additional costs incurred to reaccommodate the Codeshared Passenger on a third-party carrier acceptable to United,

Page 5 of 35

on the same route or with a routing that duplicates as closely as practicable, the Codeshared Passenger’s original routing, in the same class of service if available, or if not, in a higher class of service, and (ii) any reasonable hotel, meal, and other incidental costs associated with the reaccommodation.

2.7 The Parties agree to comply with the Technical Implementation and System Links requirements set forth in Annex C hereto.

2.8 **

3. IMPLEMENTATION EXPENSES

3.1 Each Party shall bear its own costs and expenses of performance under this Agreement, including, without limitation, costs and expenses associated with the following, unless otherwise agreed in writing between the Parties:

(a) any systems to support the automation of procedures and settlement relating to the Codeshared Flights (e.g., PNR exchange, yield management, revenue accounting, etc.), including routine maintenance thereof; and

(b) roadside, exterior, check-in, concourse, gate and baggage service signage placed at airports and city ticket offices in locations served by the Codeshare Flights in order to facilitate travel on the Codeshare Flights.

3.2 Each Party shall retain all right, title and interest in systems, software, signage, equipment and facilities funded by it. Ownership of jointly funded items shall be determined by the Parties in advance of each specific project.

4. INVENTORY CONTROL AND PROCEDURES

4.1 Subject to the rights of each Party to manage its seat inventory, including the seat inventory on the operational flights of any other airline(s) that the Party has access to under a capacity purchase agreement, the Parties agree to use commercially reasonable efforts to pursue the best solution to maximize revenue, maintain the integrity of Great Lakes’ inventory system and not compromise United’s ability to sell its product. Accordingly, the Parties agree to implement the following initiatives:

a. establish Seamless Availability and Direct Sell links between their respective ARSs,

b. use commercially reasonable efforts to pursue the development required for United to Cascade third party CRS Direct Access Availability, Seamless Availability and Direct Sell requests to Great Lakes, which will include Sold As Information and Point Of Sale data as is available to United in a manner to be mutually agreed by the Parties,

c. establish the ability to make advance seat assignments on each other’s flights. Each of the Parties further agrees to expend such amounts as may be reasonably required on mutually agreed systems development. To the extent the Parties disagree about which Party’s system should be modified to make it more compatible with the other Party’s system, the Parties agree to continue to work together to use commercially reasonable efforts to modify their systems.

Page 6 of 35

Detailed procedures for implementing and maintaining seat inventory access will be as agreed by the Parties.

4.2 Great Lakes will, subject to the remaining provisions of this paragraph and Section 4.1, determine, independently and at its sole discretion, the number of seats on its flights (including flights it operates as Codeshare Flights) that will be made available by it in a particular reservation booking designator provided that Great Lakes does not discriminate against United vis a vis other air carriers with respect to inventory access. With respect to inventory management on the Codeshare Flights, the Parties acknowledge and agree that Great Lakes will manage its seat inventories in a manner that provides an incentive for United to sell the inventory of Great Lakes and for Great Lakes to accept the inventory requests of United without subjecting Great Lakes to disproportionate risk of revenue dilution and while preserving for Great Lakes the integrity of its inventory management system in order for Great Lakes to maximize its profitability.

4.3 This Section 4.3 shall govern the published fares and fare rules, including carrier imposed surcharges and commissions applicable thereto, of United offered on Codeshared Flights as follows:

(a) For routes served by only Great Lakes, or its Affiliates, **

(b) For routes served by both Parties or their Affiliates, on both a non-stop or both a connecting basis, United will file either those fares and fare rules filed for its own flights on such route or those fares and reasonably comparable (as determined by Great Lakes) fare rules as those filed by Great Lakes on such route, at its sole discretion.

(c) For routes where Great Lakes, or its Affiliates, offers non-stop service and United, or its Affiliates, offers connecting service, United on the non-stop service for such route will file the fares and reasonably comparable (as determined by Great Lakes) fare rules as those filed by Great Lakes on the non-stop service for such route.

(d) United will cause its agents and distributors to sell Codeshared Flights operated by Great Lakes in a manner that is consistent with the requirements of Section 4.3(a), (b) and (c).

(e) United will not be in breach of the rules set forth in Section 4.3(a), (b), (c) or (d) if it is in compliance with such rules within forty-eight (48) hours after the applicable fare or fare rule is published by Great Lakes.

(f) In the event of United’s breach of Section 4.3(a), (b), (c) or (d), Great Lakes shall have the right, in its sole discretion, after one day’s prior written notice to United, to restrict or close the inventory access of United or temporarily remove the Code of United from the flight(s) in question.

(g) Nothing in this Agreement shall prevent Great Lakes from unilaterally establishing its own fares and fare rules for flights operated by it or United from

Page 7 of 35

(i) initiating and operating its own service in any origin and destination city pair at any time; or (ii) offering any fare(s), discount(s) or rebate(s) of any kind for interline itineraries valid on airlines, other than United or GREAT LAKES, on any origin and destination city pair.

(h) In implementing the rules established by this Section 4.3, there will be no discussion between the Parties concerning fares and fare rules. United will determine fares and fare rules of Great Lakes by observing published tariffs. Any communication concerning this Section will be undertaken by the Parties’ attorneys.

For purposes of this Section, route means the exact airport to airport origin and destination.

United shall establish fares and rates, subject to the provisions of the applicable air transport agreements of the United States, on the one hand, and the governments of any country to which the Parties shall provide service pursuant to this Agreement, on the other hand.

5. MARKETING AND PRODUCT DISPLAY

5.1 The Codeshared Flights will be marketed and promoted by United under its Code. Each Party shall ensure that its respective advertising and promotions comply with all applicable governmental laws, rules and regulations of any applicable Competent Authority. United shall comply with 14 C.F.R. Parts 257 and 258, and any other applicable rules regarding the disclosure and holding out of Codeshared Flights provided for herein in the jurisdiction where such rules apply. United shall disclose to the extent required by Applicable Law through industry-approved schedule and selling mechanisms, to consumers, travel agents and others selling the Codeshared Flights, as well as through any advertising, point-of-sale disclosures, and any other appropriate means, that each Codeshared Flight is a flight of and operated by Great Lakes. Such information shall be given before a reservation is made and in any event at the earliest reasonable opportunity and before the passenger arrives at the airport, in accordance with Applicable Law. In addition, each Party shall use commercially reasonable efforts to implement procedures to disclose Great Lakes and the appropriate departure and arrival terminal at the earliest possible opportunity and in particular at the point of sale.

5.2 United may identify the Codeshared Flights, in accordance with Applicable Law, in Airline Guides, CRSs, Reservations Systems and other sources of airline schedule information using United’s Code. Any costs incurred for the publication of Marketing Flights or connections to and from such flights in Airline Guides, CRSs, Reservation Systems and other sources of airline schedule information shall be borne by United. Each Party shall include the Codeshared Flights in its Reservations Systems.

5.3 Unless otherwise specified in Annex B, United shall file its standard schedule data for the Codeshared Flights in such Codeshared Route using the traffic restriction code “Y” or “O” (or any successor code), as defined in the IATA Standard Schedules Information Manual, Appendix G, in order to suppress the display of United’s Codeshared Flights on Codeshared Routes (i.e., United’s Codeshared Flights on such route will be limited to passengers connecting online to another flight operated by United or its Affiliate) or as mutually agreed by the Parties.

Page 8 of 35

5.4 Unless otherwise agreed, all information and advertising materials produced with the aim of promoting the Codeshared Flights shall clearly identify both Parties. All joint advertising and promotion of the Codeshared Flights shall be subject to prior agreement between the Parties and the costs of such joint advertising and promotion shall be shared based on prior agreement.

5.5 Each Party may use its own flight number in referencing the Codeshared Flights except that only Great Lakes’ flight number shall be used in actual flight operations (e.g., air traffic control).

6. TRAFFIC DOCUMENT ISSUANCE AND FINANCIAL SETTLEMENT

6.1 Passenger traffic documents for use on the Codeshared Flights may be issued by either Party, or by third parties with whom the Parties from time to time have interline traffic agreements.

6.2 All United Flight Coupons honored on Codeshared Flights shall be uplifted by Great Lakes, which is responsible for processing and billing of such documents as follows:

(a) Great Lakes shall xxxx uplifted coupons to the Ticketing Carrier using the normal interline settlement process of the ACH Clearing House. Subject to Section 6.2(b) and 6.2(c), United Flight Coupons shall be treated for proration and billing purposes as if they showed Great Lakes’s designator Code in the carrier Code box of United Flight Coupons. Such United Flight Coupons will be prorated and billed according to the Special Prorate Agreement between Great Lakes and the Ticketing Carrier, or, in the absence of an applicable Special Prorate Agreement, in accordance with the ACH Manual of Procedures, as applicable.

(b) If Great Lakes does not have an interline traffic agreement with a Ticketing Carrier that issued a United Ticket, and is unable to obtain satisfactory settlement, Great Lakes may xxxx such coupon to United as an exceptional item (i.e., via correspondence) and such coupons shall be valued for billing and proration purposes in accordance with the applicable bilateral agreement. Any bilateral agreement between United and Ticketing Carrier shall not apply to the Codeshared Flights unless Great Lakes has given explicit agreement to such application.

(c) If Great Lakes has an interline traffic agreement with a Ticketing Carrier that issued a United Ticket but is unable to obtain satisfactory settlement, United shall assist Great Lakes in settling such account but shall not be liable for any losses incurred due to an unsatisfactory settlement.

6.3 The Carriers agree that for tickets sold by United on Codeshare Flights, Great Lakes shall be responsible for booking fees assessed by any CRS vendors, including CRSs operated by third parties and CRSs providing hosting services to any of the Carriers. The Carriers will request the CRS vendors to directly xxxx Great Lakes for such booking fees if feasible. If such direct billing is not feasible, the Carriers shall xxxx each other monthly and shall provide documentation that is reasonably acceptable to the other Carrier of such fees from each CRS vendor.

6.4 To support interline billing by Great Lakes to third-parties and involuntary rerouting of United Tickets by Great Lakes, United hereby waives endorsement requirements for Great Lakes with respect to all United Flight Coupons and other coupons intended for flights sold under the Code of United. Unless otherwise agreed in writing by the Parties, such waiver shall be effective thirty (30) days before the implementation date of the first Codeshared Flight, and shall remain in effect for ninety (90) days after the Termination Date of this Agreement to facilitate the reaccommodation of any Codeshared Passengers ticketed for travel after the Termination Date.

6.5 Differences that may appear after the billing process has been completed shall be rectified by written correspondence or a meeting between the Parties.

6.6 United has filed with ATPCO a TCN Codeshare Agreement, in which United has provided the range of its Marketing Flight numbers, as required. United will be responsible, throughout the term of the Codeshare Agreement, for updating its Marketing Flight numbers with ATPCO.

7. FACILITIES

The Parties acknowledge the importance of maintaining functional and accurate signs identifying Great Lakes and United, as appropriate, to facilitate passenger convenience and to avoid passenger confusion at airports served by the Codeshare Flights. The Parties shall cooperate on the placement of such signs, subject to the approval of the relevant airport authority or other lessors.

8. TRAINING

8.1 Except as otherwise agreed, each Party shall provide or arrange, at its own cost and expense, all initial and recurring training of its personnel to facilitate the Codeshared Flights and operations at airports served by the Codeshared Flights, including reservations and ticket offices, and other points of contact between the Parties and the public. This training shall include passenger service, reservations and sales activities, and in-flight service involving the Codeshared Flights, all as mutually agreed.

8.2 The Parties shall share any training materials (except trade secrets and legal advice) developed to support the Codeshared Flights. All intellectual property or similar rights to any materials exchanged shall remain with the Party who originally developed such materials.

9.1 The Parties shall cooperate in matters of security procedures, requirements, and obligations at all airports served by the Codeshared Flights.

9.2 Great Lakes reserves the right to apply the provisions of its own security programs to the carriage of all passengers, baggage and cargo on board the Codeshared Flights, but shall, at a minimum, comply with the standards set forth by the relevant Competent Authorities, with the understanding that safety and security are of the utmost importance to both

Page 10 of 35

carriers. Such provisions may include any then applicable procedures used for the physical screening of passengers, baggage or cargo, interviewing of passengers, and/or selective loading of baggage or cargo.

9.3 The Carrier that originates the customer travel on Codeshare Flights (provides all boarding passes and checks the customer luggage to their final destination) shall assure that the customer is properly documented for entry into the destination country and properly documented for any transit points enroute. Any fines, penalties, deportation and detention expenses resulting from violations of government entry or transit requirements, even for passengers that willfully engage in illegal entry tactics, shall be the sole responsibility of the Carrier that originates the customer travel.

10. SAFETY AND MAINTENANCE

10.1 Great Lakes has operational control of the aircraft and final authority and responsibility concerning the operation and safety of the aircraft and its passengers, including Codeshared Passengers. Great Lakes shall employ the same high standards of safety, security and loss prevention policies on the Codeshared Flights as on its own flights. The Parties agree that in case of a major accident or emergency involving a Codeshare Flight, Great Lakes shall immediately contact United, furnishing every possible information upon United’s request. Further emergency support shall be in accordance with procedures agreed between the Parties.

(d) the other Party is not in compliance with Sections 10.3 or 10.4 of this Agreement.

17.4 Throughout the Term, United has the right to suspend, or partially suspend, performance of or terminate this Agreement immediately by giving written notice to Great Lakes in the event that Great Lakes at any time discontinues or suspends ** or more of the Codeshared Flights operated by it other than due to Force Majeure as defined in Section 21. For clarification purposes, the termination right stated in Section 17.7 shall remain applicable.

17.5 If a Party suspends this Agreement pursuant to this Section, as soon as the reason for the suspension no longer exists it shall notify the other Party and this Agreement will recommence within ** days after the date of notice under the same terms and conditions, or under amended terms and conditions in accordance with Section 30.

Page 16 of 35

all costs, fees, and expenses incidental thereto, of every type and nature whatsoever, including without limitation those involving (i) death of or injury to any person including, but not limited to, Great Lakes’ officers, employees and agents, (ii) loss of, damage to, or destruction of any property whatsoever, including any loss of use thereof, and (iii) trademark, service xxxx or trade name infringement, provided that such liabilities, claims, judgments, damages or losses are caused by or arise out of (or are alleged to be caused by or arise out of) any alleged acts or omissions of Great Lakes or its officers, employees, or agents which are in any way related to its obligations to be performed under this Agreement. United shall give Great Lakes prompt notice of any claim made or suit instituted against United which, if successful, would result in indemnification of United hereunder, and United shall have the right to compromise or participate in the defense of same to the extent of its own interest.

(ii) United hereby assumes liability for, and shall indemnify, defend, protect, save and hold harmless Great Lakes, its officers, agents, and employees from and against any and all liabilities, claims, judgments, damages, and losses, including all costs, fees, and expenses incidental thereto, of every type and nature whatsoever, including without limitation those involving (i) death of or injury to any person including, but not limited to, United’s officers, employees and agents, (ii) loss of, damage to, or destruction of any property whatsoever, including any loss of use thereof, and (iii) trademark, service xxxx or trade name infringement, provided that such liabilities, claims, judgments, damages or losses are caused by or arise out of (or are alleged to be caused by or arise out of) any alleged acts or omissions of United or its officers, employees, or agents which are in any way related to its obligations to be performed under this Agreement. Great Lakes shall give United prompt notice of any claim made or suit instituted against Great Lakes which, if successful, would result in indemnification hereunder, and Great Lakes shall have the right to compromise or participate in the defense of same to the extent of its own interest.

18.2 A Party (the “Indemnified Party”) that believes it is entitled to indemnification from the other Party (the “Indemnifying Party”) pursuant to the terms of this Agreement with respect to a third-party claim shall provide the Indemnifying Party with written notice (an “Indemnification Notice”) of such claim (provided, however, that the failure to give such notice shall not relieve the Indemnifying Party of its obligations hereunder except to the extent that such failure is materially prejudicial to the Indemnifying Party), and the Indemnifying Party shall be entitled, at its own cost and expense and by its own legal advisors, to control the defense of or to settle any such third-party claim. The Indemnifying Party shall have the right to elect to settle any such claim for monetary Damages only, subject to the consent of the Indemnified Party; provided, however, if the Indemnified Party fails to give such consent to a settlement that has been agreed upon by the Indemnifying Party and the claimant in question within ** days of being requested to do so, the Indemnified Party shall assume the defense of such claim or demand and regardless of the outcome of such matter, the Indemnifying Party’s liability hereunder shall be limited to the amount of any such proposed settlement. If the Indemnifying Party fails to take any action against the third-party claim that is the subject of an Indemnification Notice within ** days of receiving such Indemnification Notice, or

Page 17 of 35

otherwise contests its obligation to indemnify the Indemnified Party in connection therewith, the Indemnified Party may, upon providing prior written notice to, but without the further consent of, the Indemnifying Party settle or defend against such third-party claim for the account, and at the expense, of the Indemnifying Party. Except as set forth in this Section 18.3, the Indemnified Party shall not enter into any settlement or other compromise or consent to a judgment with respect to a third-party claim to which the Indemnifying Party has an indemnity obligation without the prior written consent of the Indemnifying Party.

18.3 Each Indemnified Party shall have the right, but not the duty, to participate in the defense of any claim with attorneys of its own choosing and at its own cost, without relieving the Indemnifying Party of any obligations hereunder. In addition, even if the Indemnifying Party assumes the defense of a claim, the Indemnified Party shall have the right to assume control of the defense of any claim from the Indemnifying Party at any time, and to elect to settle or defend against such claim; provided, however, the Indemnifying Party shall have no indemnification obligations with respect to such claim except for the costs and expenses of the Indemnified Party (other than attorneys’ fees incurred in participating in the defense of such claim) incurred prior to the assumption of the defense of the claim by the Indemnified Party.

18.4 Each Party further agrees to indemnify, defend and hold harmless the other Party from and against any and all Taxes (as defined in Annex A), or assessments, as the case may be, levied upon or advanced by the Indemnified Party, but that ultimately the Indemnifying Party would be responsible for paying, which resulted from any transaction or activity contemplated by this Agreement.

18.5 The rights and obligations of the Parties under this Section 18 shall survive the Termination Date or expiration of this Agreement.

(b) The Ticketing Carrier shall collect any interlineable Ticket Taxes levied in connection with the sales of the Codeshared Flights.

Great Lakes shall remit to taxation authorities all such interlineable Ticket Taxes.

(c) Great Lakes may xxxx the Ticketing Carrier for any Ticket Taxes due or payable on or measured by passenger enplanement and payable or remittable by Great Lakes or United that should have been collected at the time of ticket sale or travel document issue by the Ticketing Carrier.

(d) If the Ticketing Carrier is a third-party, United shall use commercially reasonable efforts to cause such third-party to implement the foregoing provisions.

20.3 If either Party receives notice from any taxation authority with respect to any assessment or potential assessment or imposition of any Tax (collectively, an “Assessment”) relating to this Agreement, that the other Party may be responsible for paying, directly or indirectly, the Party so notified shall inform the other Party in writing within ** days of receipt of such notice. If the Party receiving such notice from a taxation authority is or will be required to pay any Assessment for which the other Party is ultimately responsible, it shall be entitled to be indemnified against such Assessment in accordance with Section 18.5. The Indemnifying Party shall have the option to defend or contest such Assessment in accordance with the procedures set forth in Section 18.

21. FORCE MAJEURE

matters or things, whether or not of a similar nature, which are beyond the control of the Carrier and which shall directly or indirectly, prevent, delay, interrupt, or otherwise adversely affect the furnishing, operation or performance of such Carrier’s obligation hereunder (“Force Majeure Events”); provided, however, that the Carrier so affected shall take all commercially reasonable steps to cure such nonperformance or delay and shall promptly continue performance hereunder once the Force Majeure Event is removed. The Carrier who is affected by a Force Majeure Event shall promptly notify the other Carrier of the occurrence of such Force Majeure Event. In the event of a strike by a Carrier’s employees, such Carrier will use its commercially reasonable efforts to perform under this Agreement.

22. GOVERNING LAW AND DISPUTE RESOLUTION

Each of the Parties irrevocably submits to the exclusive jurisdiction of such arbitration and expressly and irrevocably waives its rights to bring suit against the other Party in any court of law except for the limited purposes of enforcing an arbitral award obtained in respect of a Dispute, or for obtaining any injunctive, temporary or preventative order or similar order available to it under the laws of any jurisdiction for a breach or threatened breach by the other Party of this Agreement which threatens irreparable damage.

Page 23 of 35

27. SEVERABILITY

If any provision of this Agreement is or becomes illegal, invalid or unenforceable under the law of any jurisdiction, such provision shall be severed from this Agreement in the jurisdiction in question and shall not affect the legality, validity or enforceability of the remaining provisions of this Agreement nor the legality, validity or the enforceability of such provision under the law of any other jurisdiction; unless, in the reasonable opinion of either Party, any such severance affects the commercial basis of this Agreement, in which case the Party shall so inform the other Party and the Parties shall negotiate in good faith to agree upon modification of this Agreement so as to maintain the balance of the commercial interests of the Parties. If, however, such negotiations are not successfully concluded within ** days from the date a Party has informed the other that the commercial basis has been affected, either Party may terminate this Agreement by giving at least ** days’ prior written notice to the other Party.

28. FURTHER ASSURANCES

29. MISCELLANEOUS

29.1 This Agreement contains the entire agreement between the Parties relating to its subject matter, and supersedes any prior understandings or agreements between the Parties regarding the same subject matter. This Agreement may not be amended or modified except in writing signed by a duly authorized Representative of each Party.

29.2 The relationship of the Parties hereunder shall be that of independent contractors. Neither Party is intended to have, and neither of them shall represent to any other Person that it has, any power, right or authority to bind the other, or to assume, or create, any obligation or responsibility, express or implied, on behalf of the other, except as expressly required by this Agreement or as otherwise permitted in writing. Nothing in this Agreement shall be construed to create between the Parties and/or the Parties’ Representatives any partnership, joint venture, employment relationship, franchise or agency (except that Great Lakes shall have supervisory control over all passengers during any Codeshared Flight, including any employees, agent or contractors of United who are on board any such Codeshared Flight).

Page 24 of 35

29.3 In the event that there occurs a substantial change in market conditions in general or in the condition of either Party, which change is not substantially the result of an act or omission of the Party requesting a change or amendment to this Agreement, and which change has a material adverse effect on either Party to this Agreement, then United or Great Lakes may propose a review of or amendment to this Agreement to limit or expand any of the terms, to extend the relationship to additional activities or city-pair destinations or otherwise to modify in any way the transactions or relationships contemplated in this Agreement. However, neither United nor Great Lakes will have any obligation, for any reason, to effect such an amendment.

29.5 This Agreement may be executed and delivered by the Parties in separate counterparts, each of which when so executed and delivered shall be an original, but all of which taken together shall constitute one and the same instrument.

29.6 No failure to exercise and no delay in exercising, on the part of any Party, any right, remedy, power or privilege hereunder, shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof of the exercise of any other right, remedy, power or privilege. The rights, remedies, powers and privileges herein provided are cumulative and not exclusive of any rights, remedies, powers and privileges provided by law. The failure of any Party to insist upon a strict performance of any of the terms or provisions of this Agreement, or to exercise any option, right or remedy herein contained, shall not be construed as a waiver or as a relinquishment for the future of such term, provision, option, right or remedy, but the same shall continue and remain in full force and effect. No waiver by any Party of any term or provision of this Agreement shall be deemed to have been made unless expressed in writing and signed by such Party.

29.7 This Agreement is the product of negotiations between Great Lakes and United, and shall be construed as if jointly prepared and drafted by them, and no provision hereof shall be construed for or against any Party by reason of ambiguity in language, rules of construction against the drafting Party, or similar doctrine.

29.8 NEITHER PARTY SHALL BE LIABLE FOR ANY EXEMPLARY, PUNITIVE, SPECIAL OR CONSEQUENTIAL DAMAGES, INCLUDING LOST REVENUES, LOST PROFITS OR LOST PROSPECTIVE ECONOMIC ADVANTAGE, ARISING FROM ANY PERFORMANCE OR FAILURE TO PERFORM UNDER THIS AGREEMENT, EVEN IF SUCH PARTY KNEW OR SHOULD HAVE KNOWN OF THE POSSIBILITY THEREOF, AND EACH PARTY HEREBY RELEASES AND WAIVES ANY CLAIMS AGAINST THE OTHER PARTY REGARDING SUCH DAMAGES. FOR THE AVOIDANCE OF DOUBT, THE PARTIES AGREE THE FOREGOING SHALL NOT LIMIT A PARTY’S OBLIGATION TO INDEMNIFY THE OTHER IN ACCORDANCE WITH SECTION 18 FOR DAMAGES ARISING OUT OF OR RELATING TO A CLAIM, SUIT OR CAUSE OF ACTION BY A THIRD PARTY.
