Section 2.07 DOT Certification. Pinnacle has and shall maintain DOT Certification and all other permits, licenses, certificates and insurance required by governmental authorities and Article IX hereof to enable Pinnacle to perform the services required by this Agreement.

Section 2.08 Compliance With Governmental Regulations. All flight operations, dispatch operations and flights and all other operations undertaken by Pinnacle pursuant to this Agreement shall be conducted and operated by Pinnacle in strict compliance with all Governmental Regulations, including, without limitation, those relating to airport security, the use and transportation of hazardous materials, flight crew and mechanic qualifications and licensing requirements, crew training and hours. All Equipment shall be operated and maintained by Pinnacle in strict compliance with all Governmental Regulations, Pinnacle’s own operations manuals and maintenance manuals and procedures, and all applicable equipment manufacturer’s instructions. At all times, Pinnacle shall operate with the highest standards of care.

Section 2.09 Quality of Service. Northwest policies, procedures, performance standards (including but not limited to Northwest’s “Customers First” customer service plan) and means of measurement thereof concerning the provision of air passenger and air cargo services shall be applicable to all services provided by Pinnacle under this Agreement. Pinnacle shall achieve at least the same quality of airline service provided by Northwest, subject to limitations imposed by the type of Aircraft used by Pinnacle, its route network, the availability of equipment and facilities at the Service Cities and the performance by Northwest of its obligations under this Agreement. Pinnacle shall maintain adequate staffing levels to ensure at least the same level of customer service and operational efficiency that Northwest achieves; Pinnacle shall cooperate with Northwest in any way necessary or desirable to provide such comparable level of customer service in connection with the operation of Regional Airline Services; and Pinnacle shall maintain new hire and recurrent training programs for all job descriptions which are reasonably acceptable to Northwest.

Section 2.10 Service Standards. Without limiting Section 2.09, Pinnacle shall achieve the following specific performance standards (subject to Section 5.15(b)(iii) and (iv) below):

(a) Minimum Completion Factor. Pinnacle shall achieve not less than a [***] completion factor for all Scheduled Flights which are scheduled to be operated by Pinnacle during each Performance Period. Scheduled Flights which are

Execution Copy

cancelled at Northwest’s request (as determined by Northwest’s System Operations Control (“SOC”) operations reporting group) will not be included in calculating Pinnacle’s completion factor, and station overflys due to no passenger load will not be considered a cancellation.

(b) Minimum On-Time Reliability. Pinnacle shall achieve a [***] on-time arrival within zero minutes factor and a [***] on-time departure within zero minutes factor for all Scheduled Flights which are scheduled to be operated by Pinnacle during each Performance Period. Scheduled Flights which are delayed at Northwest’s request will not be included in calculating Pinnacle’s on-time arrival and on-time departure factors.

(c) Mishandled Luggage Factor. The number of incidents of mishandled luggage by Pinnacle shall not exceed twelve [***] enplaned revenue passengers during any Performance Period. The number of incidences of mishandled luggage shall be determined by Northwest by dividing (i) the total number of Pinnacle-caused claims at Pinnacle Service Cities, Northwest Service Cities, Contracted Service Cities and the Hub Cities during the applicable Performance Period, by (ii) the total number of enplaned revenue passengers during such Performance Period as reported by Northwest. Notwithstanding the foregoing, the parties agree that incidents of mishandled luggage where (i) DTW is the responsible station, and (ii) such incidents are not due to Pinnacle’s actions, will not be included in the mishandled luggage factor unless and until Pinnacle performs luggage handling for its Scheduled Flights at DTW. In the event incidents of mishandled luggage at DTW are excluded from the mishandled luggage factor pursuant to the preceding sentence, the number of enplaned revenue passengers at DTW during the corresponding time period will also be excluded from the mishandled luggage factor, and no penalties will be applicable as to such passengers. The parties further agree that mishandled luggage at MSP will not be included in the mishandled luggage factor in the event Mesaba fails to perform luggage handling in accordance with the standards set forth in the handling agreement between Pinnacle and Mesaba and Northwest is unable to make sufficient space available at MSP to allow Pinnacle to perform luggage handling for its Scheduled Flights or make other mutually satisfactory luggage handling arrangements. In the event incidents of mishandled luggage at MSP are excluded from the mishandled luggage factor pursuant to the preceding sentence, the number of enplaned revenue passengers at MSP during the corresponding time period will also be excluded from the mishandled luggage factor, and no penalties will be applicable as to such passengers.

(d) Customer Complaints Factor. The number of customer complaints received by Northwest in respect of Regional Airline Services shall not exceed [***] enplaned revenue passengers during any Performance Period. The number of customer complaints shall be determined by Northwest by dividing (i) the total number of Pinnacle -caused complaints during the applicable Performance Period, by (ii) the total number of enplaned revenue passengers during such Performance Period as reported by Northwest.

Execution Copy

(e) Vendor Performance. Northwest intends to enter into one or more ground handling agreement(s) to handle Pinnacle flights in DTW and MSP with a Northwest-selected vendor(s). If Northwest enters into such an agreement, then Northwest agrees that such agreement will include performance metrics substantially similar to the performance metrics in the ground handling services agreement between Northwest and Pinnacle in place as of January 1, 2007. Should the vendor not meet or exceed the performance standards in the ground handling agreement for any three month period in MSP or DTW, then the “s” coded delays and cancels at the applicable airport will be removed from Pinnacle’s performance for the applicable period in determining whether Pinnacle has satisfied the performance metrics under this Agreement. Should Pinnacle be the ground handler in MSP or DTW, the “s” coded delays or cancel will remain. If Northwest does not enter into an agreement with a Northwest-selected vendor to handle Pinnacle flights in DTW and MSP, or if Northwest enters into such an agreement but such agreement does not include performance metrics substantially similar to the performance metrics in the ground handling services agreement between Northwest and Pinnacle in place as of January 1, 2007, and the vendor handling Pinnacle flights in DTW and MSP does not, for any three month period in MSP or DTW, meet or exceed the performance metrics in the ground handling services agreement between Northwest and Pinnacle in place as of January 1, 2007 (notwithstanding that such metrics may not be applicable to such vendor as between such vendor and Northwest), then the “s” coded delays and cancels at the applicable airport will be removed from Pinnacle’s performance for the applicable period in determining whether Pinnacle has satisfied the performance metrics under this Agreement

Section 2.11 Service Recovery

(a) Passenger Amenities. Pinnacle agrees to provide passenger amenities, including, without limitation, denied boarding compensation, which Northwest provides under Rule 245 of the Domestic General Rules No. 1 issued by Airline Tariff Publishing Co. and ATA Resolution No. 120.20 or pursuant to any similar contractual arrangement now existing or hereafter in effect or applicable to Northwest. In any Pinnacle Service City, Contracted Service City or Hub City, Pinnacle agrees (i) to handle oversold Scheduled Flights and the payment of denied boarding compensation in accordance with Northwest’s standard policies and procedures, (ii) to pay the full cost of providing passenger amenities (either directly to the affected passengers or to Northwest as reimbursement for the amounts paid by Northwest to such passengers) with the exception of denied boarding compensation resulting from inventory oversales or other actions of Northwest, and (iii) to report all denied boarding data to Northwest via both the standard Northwest Ticket Agent Report (“TAR”) and the standard Northwest Yield Management Flight Close-Out Denied Boarding Mask (“MASK”). In any Pinnacle Service City, Contracted Service City or Hub City, for denied boarding compensation resulting from inventory oversales or the actions of Northwest, Pinnacle will pay the appropriate amount of denied boarding compensation to the affected passengers and will invoice Northwest for such amount pursuant to Section 5.07 below. Any such invoice will include sufficient detail and supporting documentation to allow Northwest to verify the

Execution Copy

invoiced amount. Notwithstanding the foregoing, Pinnacle shall be responsible for any discrepancy between the TAR and the MASK, and Northwest will invoice Pinnacle for any amounts due based on reconciliation of those two reports. In Northwest Service Cities, Northwest will provide all passenger amenities, including but not limited to baggage delivery, at its sole cost.

(b) Destination by other Means. If Pinnacle transports a revenue passenger to his or her destination by another means (bus, train, taxi, etc.) due to a flight cancellation, Northwest shall reimburse Pinnacle for the actual transportation costs incurred to transport the passenger by such other means; provided, however, that if the flight cancellation is necessitated by acts of Pinnacle (e.g., crew curfews, maintenance-related delays, etc.), Pinnacle will pay the costs incurred to transport the passenger by such other means. Pinnacle shall use its best efforts to minimize the transportation of passengers by other means and the costs associated therewith.

Section 2.12 Annual Operating Plan. At least 90 days prior to January 1 of each year during the term of this Agreement, Pinnacle and Northwest shall confer and prepare an operating plan for the succeeding calendar year, which plan shall include (i) Northwest’s forecast with respect to the schedule and routing for all Scheduled Flights for such year, (ii) Northwest’s forecast of the Service Cities to which Pinnacle shall operate Regional Airline Services, (iii) Northwest’s forecast of specific dates for the commencement of service to new Service Cities, if any, (iv) Northwest’s forecast of the number of Aircraft to be added to or removed from Pinnacle’s fleet (subject to Section 3.02), and (v) such other matters as Northwest and Pinnacle shall determine (as amended in accordance with this Section 2.12, the “Annual Operating Plan”). Northwest and Pinnacle shall meet and confer on a quarterly basis (or more frequently if requested by either Northwest or Pinnacle) to review the implementation of the Annual Operating Plan and to discuss any changes to the Annual Operating Plan. In the event Northwest elects to alter the Annual Operating Plan during the course of a year, Northwest shall use its reasonable best efforts to provide at least sixty (60) days prior notice to Pinnacle. Notwithstanding the foregoing provisions of Section 2.12, Northwest shall promptly notify Pinnacle of any determination by Northwest to increase or decrease Pinnacle’s fleet size, and, except as provided in Section 3.02(a)(ii) and Section 3.02 (a)(iii) below, Northwest shall give Pinnacle no less than ninety (90) days prior notice. Northwest agrees that any substantial increases in Pinnacle’s fleet size pursuant to the preceding sentence are subject to Pinnacle’s reasonable operating constraints.

Section 2.13 Inflight Food, Beverages and Supplies. Unless otherwise mutually agreed, Pinnacle will provide Aircraft catering services, food and beverages for passengers and crews on Scheduled Flights in accordance with Northwest’s specifications and directions and at Pinnacle’s sole cost. Pinnacle shall be solely responsible for maintaining all licenses necessary for the serving of inflight food and beverages on Scheduled Flights. Northwest shall furnish Pinnacle, at Northwest’s sole cost, adequate supplies of its customary inflight supplies including, but not limited to, the Northwest inflight magazine, cups, napkins, pillows, blankets, trash bags, sick sacks, lavatory supplies, creamers, swizzle sticks and sugar in a form similar or identical to that used by Northwest. Notwithstanding anything to the contrary in this Agreement, Northwest may, at its option, require Pinnacle upon ninety (90) days prior written notice to utilize Northwest or a Northwest-designated contract agent to provide catering

Execution Copy

services, food and beverages for passengers and crews on Scheduled Flights, provided that (i) the Block Hour Rates set forth in Section 5.03 below are adjusted as necessary to eliminate the costs of catering services, food and beverages that were included in establishing the Block Hour Rates, and the Direct Costs to Pinnacle of the new arrangement will be reimbursed pursuant to Section 5.06 below, and (ii) the service standards applicable to any such Northwest-designated contract agent are either reasonably satisfactory to Pinnacle or no less stringent than the standards applicable to Northwest’s own operations.

Section 2.14 Exclusivity Arrangements. During the term of this Agreement, neither Pinnacle Corp., Pinnacle, nor any Affiliate of Pinnacle Corp. shall operate any flights to or from the Hub Cities using its own airline code or the airline code, logo, or any other identifying feature of a foreign or United States airline (other than Northwest) without the express prior written consent of Northwest. Nothing in this Agreement shall preclude Northwest from (i) entering into code share, alliance or other commercial cooperation arrangements with any other airline, or (ii) entering into similar or other arrangements with other carriers for the provisioning of regional airline services using Canadair Regional Jets, turboprop aircraft or any other aircraft to or from the Hub Cities, the same Service Cities or elsewhere.

Section 2.15 Other Operations. Pinnacle Corp. and/or an Affiliate of Pinnacle Corp. (including Pinnacle) may acquire aircraft and operate air transportation services in its own name or on behalf of or in cooperation with an airline other than Northwest, subject to Section 2.14, Section 6.01(b) and Section 6.02(a) and the following conditions: (a) prior to the commencement of the operation of twenty-four (24) or more aircraft by Pinnacle, Pinnacle Corp. and/or an Affiliate of Pinnacle Corp. in its own name or on behalf of or in cooperation with an airline other than Northwest, Pinnacle shall provide Northwest with at least ninety (90) days advance written notice of the date on which such level of operations will commence, (b) the parties shall negotiate in good faith an adjustment to the Fixed Cost Payment resulting from the operating cost efficiencies to be achieved by Pinnacle or to be shared between Pinnacle and the newly commenced operation by Pinnacle Corp. and/or an Affiliate of Pinnacle Corp., (c) any reductions in the Fixed Cost Payment shall be effective on the date the twenty-fourth aircraft commences operation, and (d) if the parties are unable to reach agreement with respect to such adjustment to the Fixed Cost Payment within thirty (30) days after the twenty-fourth aircraft commences operation, then the parties shall submit the dispute to arbitration in accordance with Section 5.10(f) below.

Should this Agreement expire or terminate for any reason, the licenses in Sections 7.01 and 7.02 shall immediately terminate (although Sections 7.07 and 7.08 shall survive), and Pinnacle shall promptly, but in any event within ninety (90) days (one hundred twenty (120) days with respect to any distinctive color scheme), take all such actions as may be necessary to change its facilities, equipment, uniforms, supplies and other materials to cease all use of any Designators and NW Identifications and to avoid any customer confusion or the suggestion or appearance that Pinnacle continues to have an operating relationship with Northwest.

Section 7.09 Bankruptcy. The parties intend that the identity of Pinnacle as the licensee hereunder is a material condition to Northwest’s granting of the licenses in 7.01 and 7.02, and that this Agreement should be construed overall as a contract for the personal services of Pinnacle. Therefore, in the event Pinnacle becomes subject to a bankruptcy proceeding, the parties intend that this Agreement shall not be assumed and/or assigned by Pinnacle or its representative without Northwest’s consent.

(b) With respect to fuel taxes, Northwest and Pinnacle shall cooperate to ensure that Pinnacle is filing appropriate fuel tax returns and refund claims to minimize Pinnacle’s taxes. Northwest shall determine which entity, Northwest or Pinnacle, shall be responsible for preparing and filing appropriate fuel tax returns and refund claims. Unless Northwest determines otherwise and notifies Pinnacle in writing, Pinnacle shall be responsible for all Pinnacle fuel tax filings and payments. Upon the request of Northwest, Northwest shall be entitled to review any actual or proposed Pinnacle fuel tax filings. Pinnacle shall notify Northwest of the commencement of any fuel tax audit. Prior to resolving any fuel tax audit, Pinnacle shall receive approval from Northwest to resolve any such audit.

(c) With respect to sales and use taxes, Northwest and Pinnacle shall cooperate to ensure that Pinnacle is filing appropriate sales and use tax returns and refund claims to minimize Pinnacle’s taxes.

Pinnacle shall in good faith and using reasonable best efforts supply Northwest with such information and documents reasonably requested by Northwest to minimize Pinnacle’s property, fuel, excise, sales, use, value-added, or similar transactional taxes. Unless Northwest determines otherwise, Pinnacle shall use its reasonable best efforts to seek any and all applicable refunds or credits of excise, sales, use, value-added, or similar transactional taxes paid by Pinnacle.

Section 8.04 Refunds of Tax. To the extent Northwest prepares and/or is responsible for pursuing any refunds or refund claims related to Pinnacle’s fuel, excise, sales, use, value-added or similar transactional taxes, Northwest shall be entitled to retain one hundred percent (100%) of the amount of any such refund, credit or other benefit. To the extent Pinnacle prepares or is responsible for pursuing any such refunds or refund claims, Pinnacle shall retain thirty percent (30%) of the amount of any such refund, credit or other benefit (inclusive of interest) it receives, and the remaining seventy percent (70%) (inclusive of interest) shall be paid to Northwest within ten (10) days of its receipt or recognition of benefit by Pinnacle.

(a) Pinnacle agrees, at its sole expense, to maintain in full force and effect the following insurance coverage with respect to Regional Airline Services:

(2) Comprehensive aviation bodily injury and property damage liability insurance with limits of not less than $1 billion combined single limit per occurrence (or such other minimum amount as may be reasonably requested by Northwest from time to time in the event Pinnacle no longer obtains airline liability insurance coverage as part of the Northwest’s aviation insurance placement), including, but not limited to, aircraft liability, passenger legal liability, premises and property damage liability, hangar keepers liability and baggage and cargo liability.

the insurance terms of this Agreement. All of the above policies shall have deductible amounts as established by Northwest, and, in any event, all of the above insurance shall be written through an insurance company or companies reasonably satisfactory to Northwest, and the certificates of insurance shall be of a type that unconditionally obligates the insurer to notify Northwest in writing at least thirty (30) days (or such lesser period as may be available for war peril coverage) in advance of the effective date in the event of any material change in or cancellation of such insurance. The policies of insurance required by paragraphs (2) and (3) of Section 9.03(a) shall provide coverage for events which occur during the policy period, are continuing in nature and not on a claims made basis, and shall include endorsements that provide:

Section 11.12 Availability of Equitable Remedies; Procedures.

(a) In the event of a breach by either party of any provision of this Agreement, the nonbreaching party may give notice thereof to the breaching party, which notice shall specify in reasonable detail the nature of the breach and shall demand that the breaching party either cure the breach or refrain from conduct constituting the breach (herein the “conduct”), as may be applicable. If (i) the breaching party has not cured the breach or refrained from the conduct, as may be applicable, within ten (10) days following receipt of the notice from the nonbreaching party, or (ii) the breaching party does not begin within ten (10) days following receipt of the notice to pursue with reasonable diligence a method of cure or begin to take steps toward ceasing the conduct where the breach or conduct is such that it requires more than ten (10) days to cure or to cease, as may be applicable, then the nonbreaching party may seek to compel performance by the breaching party in accordance with the provisions of paragraph (b) below. If, upon receiving a notice contemplated by this paragraph (a), a breaching party believes that a breach has not occurred or that the conduct specified in the notice does not constitute a breach of the provisions of this Agreement, but the breaching party nonetheless cures the alleged breach or refrains from the conduct within ten (10) days following receipt of such notice, such party may thereafter proceed in accordance with the provisions of paragraph (b) below to seek a determination of whether a breach occurred or whether the specified conduct constituted a breach of the provisions of this Agreement.

(b) Because a breach of the provisions of this Agreement could not adequately be compensated by money damages, any party shall be entitled, following notification in accordance with the provisions of paragraph (a) above, to an injunction restraining such breach or threatened breach and to specific performance of any provision of this Agreement and, in either case, no bond or other security shall be required in connection therewith, and the parties hereby consent to the issuance of such injunction and to the ordering of specific performance. Further, in the event any party refrains from the conduct of any activity alleged in a notice received pursuant to paragraph (a) above to constitute a breach of the provisions of this Agreement, such party may thereafter proceed promptly to bring an action in the District Court, County of Hennepin, State of Minnesota, for an expedited judicial determination as to whether the conduct specified constitutes a breach of the provisions of this Agreement and, upon a determination that the conduct does not constitute a breach, such party may promptly thereafter recommence such conduct.

Section 11.14 Integration and Entire Agreement. This Agreement (including the Exhibits) and the ancillary documents entered into in connection therewith are intended by the parties as a complete statement of the entire agreement and understanding of the parties with respect to the subject matter hereof and all matters between the parties related to the

subject matter herein and therein set forth. This Agreement may only be amended or modified by a written agreement between Pinnacle, on the one hand, and Northwest, on the other, which specifically references this Agreement and expressly provides for such amendment.

PARITY PAY AGREEMENT

Parity Pay Agreement

The parties agree that labor costs resulting from pay rates in excess of Parity Pay Rates for the pilot, flight attendant, customer service/reservations agent, ramp service, and mechanic workgroups will be excluded from Total Operating Cost when calculating the Margin pursuant to Section 5.10(a) and 5.13(a).

The parties agree that labor costs resulting from any significant work rule and/or Premium changes, in lieu of above Parity Pay Rates will be excluded from Total Operating Cost when calculating the Margin pursuant to Section 5.10(a) and 5.13(a).

The parties agree that labor costs resulting from benefits which are in excess of industry parity for the pilot, flight attendant, customer service/reservations agent, ramp service, and mechanic workgroups will be excluded from Total Operating Cost when calculating the Margin pursuant to Section 5.10(a) and 5.13(a).

The following definitions are used throughout this parity pay agreement:

“Comparison Airlines” shall have the meaning throughout Exhibit D as the five largest (by revenue) publicly traded U.S. domestic regional airlines operating primarily regional jet aircraft.

“Premiums” shall mean separate line, longevity, shift, license, skill or other premiums.

“RAA” shall mean the Regional Airline Association, Washington, D.C.

Definitions provided in the sections below are applicable only to the section in which such terms appear.

Pilot and Flight Attendant Employees

A. Procedures

Pinnacle’s Pay Rates for the pilot and flight attendant workgroups plus hourly impact of any Bonus Rate are compared to Parity Pay Rates.

If Pay Rates exceed Parity Pay Rates in any classification, the labor cost for that classification will be multiplied by the overage percentage and such product will be deducted from Total Operating Cost for purposes of calculating the Margin.

Significant work rule and Premiums changes are evaluated on a case by case basis.

B. Definitions

“Pay Rates” shall be the top of scale hourly rates of pay excluding Premiums.

D-1

Execution Copy

"Bonus Rate” shall be the average bonus payment divided by the timeframe covered (based on 2,080 hours per year).

"Parity Pay Rates” shall be the simple average of the Pay Rates at the Comparison Airlines within a classification. In the event that a comparison airline reduces or eliminates its Premiums and simultaneously increases its basic hourly rates, the portion of the basic hourly rate equal to the Premiums shall be excluded in determining Parity Pay Rates.

Customer Service/Reservations Agent, Ramp Service and Mechanic Employees

A. Procedures

Pinnacle’s actual Pay for customer service/reservations agent, ramp service, and mechanic workgroups is compared to projected Parity Pay.

If Pay exceeds Parity Pay in any classification, the difference will be deducted from Total Operating Cost for purposes of calculating the Margin.

Significant work rule and Premiums changes are evaluated on a case-by-case basis.

B. Definitions

“Pay” is the sum of all customer service/reservation, agent, ramp service and mechanic employees pay, including any bonus payments, within a classification (i.e. customer service agents) and shall exclude Premiums and any overtime premium.

“Parity Pay” shall be the sum of all customer service/reservation, agent, ramp service and mechanic employees Pay re-calculated using the Parity Pay Scale in place of actual Pay rates.

“Parity Pay Scale” shall be constructed by taking the average pay rates for Pay steps for all levels new hire to year 10 (top step) of the Comparison Airlines as reported by the RAA.

PASS TRAVEL PRIVILEGES

I. Overview

It is understood and agreed that Northwest has purchased and therefore controls all seat inventory on Northwest coded flights operated by Pinnacle Airlines subject to the Airline Services Agreement entered into by Northwest and Pinnacle Airlines. Northwest, in its sole discretion, shall set all prices and control all seat inventory on Pinnacle flights operated under the Northwest code.

Seats on Northwest coded flights operated by Pinnacle have an intrinsic value to Northwest and by definition persons occupying perishable seats, either on a positive space or space available basis, have revenue opportunity costs (displacement, dilution, etc.) to Northwest. Northwest will therefore establish the policies for utilizing its valuable and perishable product inventory. Northwest shall have the right, in its sole discretion, to establish pass travel policies for all persons on all Northwest Flights, including those operated by Pinnacle Airlines.

II. Definitions

“Northwest Flights” shall mean all flights operated by Northwest or Pinnacle Airlines under the Northwest designator code. If and to the extent Northwest enters into an agreement with any regional carrier other than Pinnacle Airlines that provides for pass travel on the terms set forth herein, the term “Northwest Flights” shall include the flights operated by such carrier under the Northwest designator code.

“Pinnacle Business Travel” shall mean employee travel that is required to run Pinnacle Airlines’ operations, perform employee job functions, meet with Pinnacle Airlines vendors, attend company/industry meetings/training, or conduct company business.

By definition, business travel to conduct company business would require a meeting with another person (internal or external) and the vast majority of the trip’s duration should be related to the business objective. If a pleasure trip is taken in conjunction with a business trip, the pleasure portion must be flown space available. Examples:

1. Extend business trip for personal reasons before/after.

Example: Business trip from city A to city B. After meeting is complete, employee extends trip by 2 days in city B for personal reasons. Return flight from city B is leisure space available at the employee’s normal boarding priority.

2. Round Robin. Business trip from city A to B. After business is complete, employee travels from city B to city C for personal reasons, then returns to city A.

— Flights from B to C and C to A are leisure space available.

E-1

Execution Copy

Things that would not quality as “Business” would be

- - Emergency travel, funeral travel, etc.
- - Familarization trips to visit cities where no business is conducted
- - Employee recognition/rewards
- - Any travel related to personal reasons
- - Any travel by any person who is not an employee, such as a spouse or family member

In enforcing Northwest’s business travel policies, Pinnacle Airlines must exercise good faith in determining what is valid company business and in doing so must comply with Northwest’s business travel definition and policies, as such definitions and policies may be changed from time to time by Northwest in its sole discretion.

“Leisure Travel” shall mean any travel that does not qualify as Pinnacle business travel.

III. Travel Privileges of Pinnacle Airlines Employees on Northwest Flights

1. Travel Authority Cards.

Northwest shall have the sole authority to issue travel authority cards for travel on Northwest Flights (which by definition includes Northwest coded flights operated by Pinnacle Airlines). Pinnacle Airlines will not be entitled to issue travel authority cards on Northwest Flights; however, it may submit a request for the issuance of travel authority cards for travel on Northwest to the Northwest Pass Bureau and Northwest, in its sole discretion, shall determine whether or not to grant any such request.

Requests for Travel Passes on Behalf of Any Person Other Than Employees/retirees/family members of employees of Pinnacle Airlines.

Any request for pass travel on Northwest Flights for any person other than employees, retirees or family members of employees of Pinnacle Airlines (for example, employees of airlines other than Pinnacle Airlines) may be submitted to the Northwest Pass Bureau for approval and Northwest, in its sole discretion, shall determine whether or not to grant any such request.

Northwest agrees to provide Pinnacle Airlines with [***] per year of collateral to be used for Pinnacle Airline’s business purposes (i.e., for sales, marketing, service recovery, etc.). Northwest shall determine from time to time the types of collateral to be made available to Pinnacle Airlines and the unit cost for each type of collateral product. The list of collateral products and the unit costs thereof as of the date hereof are set forth on Attachment A attached hereto. Ordering will be handled via Northwest’s GMS process.

Exhibit F

CRJ Fuel Burn (Penalty) Formulas

Note: The formulas below are to be used for the calculation of fuel burn penalty as it pertains to each performance measure and the All-in Rate. The penalty, while settled on an annual basis, is based on a monthly calculation. The result of the calculation for each performance measure shall be netted together to produce a net penalty, if one should exist. To the extent that formulas do not yet exist (i.e. Cruise Speed and Altitude), the parties mutually agree to document those formulas when those performance measures are implemented. Per Section 5.05(d), the All-in Rate is first adjusted for the variances that exist with respect to each performance measure, and then to the extent an unfavorable variance to budget exists, the penalty formula below for the All-in Rate is applied. A penalty is assessed if the cause of variance is deemed within the control of Pinnacle. An example for a month is illustrated in Attachment 1 hereto.

1. Excess Planned Fuel on Arrival (FOA)

Monthly Penalty:
(Average Actual FOA in lbs-Target) x CTC / [***] / Block Hours per Cycle x Total Block Hours x Fuel cost per gallon

Plus Margin applicable to the fuel expense reimbursement pursuant to Section 5.08 or 5.11.

Assumptions:

	•		Block Hours based on scheduled and unscheduled operations/cycles that returned legitimate FOA values (on the flight history database)

	•		Cost to Carry (CTC) varies with average enroute time; CTC = ([*] x Avg ETE) + [*]

	•		Fuel cost per gallon = actual price per gallon incurred by Northwest per Section 5.05(a)(ii) including into-plane fees and taxes.

2. Excess Planned Zero Fuel Weight (ZFW)

Monthly penalty:
(Average Planned ZFW — Average Actual ZFW-target tolerance in lbs) x CTC x CTC / [***] / Block Hours per Cycle x Total Block Hours x Fuel cost per gallon

Plus Margin applicable to the fuel expense reimbursement pursuant to Section 5.08 or 5.11.

Assumptions:

•		Block Hours based on scheduled and unscheduled operations

•		Cost to Carry (CTC) varies with average enroute time; CTC = ([*] x Avg ETE) + [*]

F-1

Execution Copy

•

Fuel cost per gallon = actual price per gallon incurred by Northwest per Section 5.05(a)(ii) including into-plane fees and taxes.

3. Excess Auxiliary Power Unit (APU) Burn

Monthly Penalty:
(Average Actual APU hrs per flight hour-Target) x Flt to Blk Hour Ratio x Total Block Hours x [***] / [***] x Fuel cost per gallon

Plus Margin applicable to the fuel expense reimbursement pursuant to Section 5.08 or 5.11.

Assumptions:

•		APU burn rate = [***] pph per Bombardier (w/Air and electric load)

•		APU runs almost exclusively w/air load but not necessarily electric. Reduction in rate w/electric removed insignificant per 9E

•		Flight hours and Block hours based on all 9E operations (scheduled and unscheduled)

•		Fuel cost per gallon = actual price per gallon incurred by Northwest per Section 5.05(a)(ii) including into-plane fees and taxes.

4. Cruise Speed To be determined.

5. Cruise Altitude To be determined.

6. All-in Rate (to be applied after adjusting for known variances to performance measures above as shown in the sample calculation set forth in Attachment 1 hereto)

Monthly Penalty:
(Actual All-in Gallons per block hour-Target) x Total Block Hours x Fuel cost per gallon

Plus Margin applicable to the fuel expense reimbursement pursuant to Section 5.08 or 5.11.

Assumptions:

•

Fuel cost per gallon = actual price per gallon incurred by Northwest per Section 5.05(a)(ii) including into-plane fees and taxes.
