                                   WITNESSETH:

WHEREAS, Pinnacle Airlines Corp., Pinnacle Airlines, Inc. and Northwest
Airlines, Inc. desire to amend certain provisions of the ASA in the manner set

NOW, THEREFORE, in consideration of the mutual covenants and agreements
contained herein, Pinnacle Airlines Corp., Pinnacle Airlines, Inc. and Northwest
Airlines, Inc. enter into this Amendment and agree as follows:

1.       Amendment of Section 4.02. Section 4.02 of the ASA is amended in its
         entirety effective June 1, 2004 to read as follows:

                  SECTION 4.02 GROUND HANDLING

                  Passenger and Ramp Handling. At Northwest Service Cities, the
                  ground handling functions shall consist of the following
                  Northwest- provided functions: (a) all gate check-in
                  activities, (b) all passenger enplaning/deplaning services,
                  including but not limited to sky cap and wheel chair services,
                  (c) aircraft loading/unloading services, including but not
                  limited to airside busing, (d) passenger ticketing, (e)
                  jetbridge maintenance, (f) janitorial services, and (g)
                  deicing services, and the following functions to be performed
                  at Pinnacle's option by Northwest (subject to the concurrence
                  of Northwest's local station manager), by Pinnacle with its
                  own employees or by a contract agent: (a) pushback, tow or
                  taxi, (b) airstarts, and (c) aircraft cleaning, including but
                  not limited to overnight cleaning, lavatory service and water
                  service (collectively, the "Ground Handling Functions"). At
                  least thirty (30) days before the start of services pursuant
                  to a schedule change, Pinnacle shall provide written notice to
                  Northwest regarding Pinnacle's election to use Northwest, its
                  own employees or a contract agent to perform the (a) pushback,
                  tow or taxi, (b) airstart, and/or (c) aircraft cleaning
                  functions at each Northwest Service City. With respect to each
                  Northwest Service City where Pinnacle





                  elects to use its own employees or a contract agent to perform
                  the (a) pushback, tow or taxi, (b) airstart, and/or (c)
                  aircraft cleaning functions, Pinnacle shall include in its
                  periodic Cycle reports (pursuant to Section 5.02(a)) the
                  following information: (x) the per turn amount incurred by
                  Pinnacle to have such functions performed by its own employees
                  or a contract agent at each such Northwest Service City, and
                  (y) the number of Cycles operated at each such Northwest
                  Service City during the period covered by the report. In the
                  event Northwest performs all Ground Handling Functions the
                  rate Northwest charges Pinnacle shall be $750 per turn
                  (cycle). If Pinnacle elects to use its own employees or a
                  contract agent to perform the (a) pushback, tow or taxi, (b)
                  airstart, and/or (c) aircraft cleaning functions, the $750 per
                  turn rate shall be reduced by the per turn amount Pinnacle
                  incurred to have those functions performed by its own
                  employees or such contract agent. At Pinnacle Service Cities,
                  Pinnacle shall provide the Ground Handling Functions. At a
                  Contracted Service City, the Ground Handling Functions shall
                  be provided utilizing a contract agent. At DTW, MSP and any
                  other Hub City, excluding MEM, Pinnacle shall use its own
                  personnel and equipment or a contract agent to perform the
                  Ground Handling Functions, except for (i) passenger ticketing,
                  (ii) airside busing, sky cap and wheel chair services, (iii)
                  jetbridge maintenance (iv) janitorial services, and (v) DTW
                  deicing services, all of which services Northwest shall
                  provide at its sole cost. In the event Pinnacle utilizes a
                  contract agent to perform substantially all of the Ground
                  Handling Functions at DTW the rate for such contracted
                  services shall not exceed $154 per turn (cycle), excluding
                  commissary charges. Any charge for such services in excess of
                  $154 per turn shall be the sole cost of Northwest. In the
                  event Pinnacle utilizes a contract agent to perform
                  substantially all of the Ground Handling Functions at MSP the
                  rate for such contracted services shall not exceed $175 per
                  turn (cycle), including commissary charges. Any charge for
                  such services in excess of $175 per turn shall be the sole
                  cost of Northwest. At MEM, Pinnacle shall use its own
                  personnel and equipment or a contract agent to perform the
                  Ground Handling Functions, except for (i) passenger ticketing,
                  and (ii) airside busing, sky cap and wheel chair services, all
                  of which services Northwest shall provide at its sole cost.

                  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, a
                  Northwest-designated contract agent, or Pinnacle's own
                  personnel and equipment to perform the Ground Handling
                  Functions at any or all of the Hub Cities, Contracted Service
                  Cities and Pinnacle Service Cities, provided that (i) in the
                  event Northwest enters into a ground handling agreement with a
                  contracted agent in a Contracted Service City, Northwest shall
                  charge Pinnacle $301 per turn (cycle) (ii) the city
                  classification pursuant to Section 5.03(b) will be revised to
                  the extent necessary, and (iii) the service standards
                  applicable to any Northwest-designated contract agent will be
                  either reasonably satisfactory to Pinnacle




                  or no less stringent than the standards applicable to
                  Northwest's own operations. Furthermore, in the event a city
                  is converted from a Contracted Service City to a Pinnacle
                  Service City, the Northwest passenger ticket counter
                  (passenger ticketing function pursuant to Section 4.02 (d)) at
                  such Service City may only be staffed by one company
                  designated by Northwest.

2.       Amendment of Article V. Article V of the ASA is amended in its entirety
         effective June 1, 2004 to read as set forth in Article V attached
         hereto in Exhibit I.

3.       Miscellaneous. This Amendment may be executed in any number of
         counterparts and by the different parties hereto on separate
         counterparts, each of which counterparts when executed and delivered
         shall be an original, but all of which shall together constitute one
         and the same instrument. This Amendment and the rights and obligations
         of the parties hereunder shall be construed in accordance with and
         governed by the internal laws of the State of Minnesota,
         notwithstanding the choice of law provisions thereof. Except as
         specifically amended, the ASA remains in full force and effect and is
         reaffirmed by each of the parties hereto. From and after the date
         hereof all references in the ASA to the "Agreement" shall be deemed to
         be references to the Agreement as amended by this Amendment.


IN WITNESS WHEREOF, the Parties hereto have executed this Amendment as of the
date and year first set forth above.

                  BHR is the then applicable Block Hour Rate in which such IOP
                  Program Incident(s) occurred, ICYC is the number of scheduled
                  Cycles cancelled in connection with the IOP Program
                  Incident(s), calculated by the following formula:
                           ICYC=Pinnacle's scheduled Cycles in Hub cancelled *
                           (((% points of Pinnacle's Scheduled Flights in Hub
                           cancelled)-(% points of Northwest scheduled flights
                           in Hub cancelled))/(% points of Pinnacle's Scheduled
                           Flights in Hub cancelled))), and
                  CYCR is the then applicable Cycle Rate by category as defined
                  in Section 5.03(b) in which such IOP Program Incident(s)

                  SECTION 5.04  FIXED COSTS.  Pinnacle's Fixed Cost Payment
arising from operation of the Aircraft shall be calculated on a monthly basis
as follows:

                  Fixed Cost Payment = [2,735,830 + (74,546 * Monthly CRJ
                  Deliveries) + (656.74 * Monthly ACDs)] * (1 + CPPIB)

                  where,

                  2,735,830 represents Pinnacle's base amount of monthly fixed
                  costs.

                  74,546 represents the payment per CRJ Aircraft delivered
                  during the month.

                  Monthly CRJ Deliveries means the number of CRJ Aircraft
                  delivered during the applicable month as set forth in the CRJ
                  Deliveries Report.

                  656.74 represents the payment per Available CRJ Day

                  Monthly ACDs means the number of Available CRJ Days for the
                  applicable month as set forth in the Available CRJ Days
                  Report.

                  SECTION 5.05      FUEL.

                  (a) Fuel Administration. As soon as practicable, Northwest
will provide to Pinnacle the following fuel-related administrative services: (i)
negotiation of fuel supply, fuel storage and into-plane service contracts for
the Aircraft, (ii) payment of all into-plane and fuel invoices in respect of the
Aircraft, (iii) monthly reconciliations (by the 15th of the following month)
with respect to fuel boarded, inventory and purchases, and (iv) monthly reports
with respect to fuel boarded by station, flight and Aircraft.

                  (b) In the event Northwest is unable to execute the
administrative functions as outlined in Section 5.05 (a) (ii) and (iii), above,
and until such time that it can, the following procedures will apply:

                                                                       Article V
                                                                    Page 5 of 19
                                                 (as amended by Amendment No. 3)


                  (i) Current reporting mechanisms in place as of the Effective
         Date of this Agreement will continue with Pinnacle reporting to
         Northwest by the 15th day of the following month, the actual gallons
         boarded and the fuel price paid (including into-plane fees and taxes).

                  (ii) Current payment mechanisms in place as of the Effective
         Date of this Agreement will continue with the exception that the
         applicable monthly Margin Payment (per Section 5.08 or Section 5.11)
         will only be paid on the actual fuel boarded multiplied by the lesser
         of the actual fuel price, including into-plane fees and taxes, and
         $.78/gallon (the "Fuel Price"). In addition, no adjustment will be made
         to bring Pinnacle's fuel expense up to $.78/gallon. The reimbursement
         will be through the Section 5.02 wire transfer occurring on the 15th
         day of the following month.

                  (c) Fuel Payment. On and after the date on which Northwest
executes the administrative functions outlined in Section 5.05(a) (ii) and (iii)
above, Northwest will charge Pinnacle on a pre-pay basis the last week of each
month for fuel to be boarded for the 1st -15th of the succeeding month. Pinnacle
will pay for that fuel through a set-off of the amount due from the Section 5.02
wire transfer on the 15th of the month for which the prepay is occurring.
Northwest will reimburse Pinnacle for this pre-pay amount through the Section
5.02 wire transfer on the 30th of the month. Likewise, Northwest will charge
Pinnacle on a pre-pay basis the second week of the month for fuel to be boarded
for the 16th-end of month. Pinnacle will pay for that fuel through a set-off of
the Section 5.02 wire transfer on the 30th of the month for which the prepay is
occurring. By the 15th of the following month, Northwest will reconcile the
pre-paid fuel expense for the preceding month with the actual expense (at a
price not to exceed the Fuel Price), and charge or credit Pinnacle with the
difference, including reimbursement for the second half pre-pay. This
reimbursement and month end adjustment for the preceding month will be handled
via the Section 5.02 wire transfer occurring the 15th day of the following month
through additional payment or set-off.

                  The pre-pay will be based on using half of Pinnacle's prior
month actual boarded volume at the Fuel Price.

                  Pinnacle shall have the right to audit on a semi-annual basis
the determination of the number of gallons of aircraft fuel boarded and shall
report any disputes to Northwest. Any dispute not reported to Northwest within
thirty (30) days of the conclusion of such audit shall be deemed waived.

                  Northwest's fuel department shall have the right to audit on a
monthly basis the determination of the number of gallons of aircraft fuel
boarded and fuel price paid and shall report any disputes to Pinnacle. Any
dispute not reported to Pinnacle within thirty (30) days of the conclusion of
such audit shall be deemed waived.

                  (d) Pinnacle Reporting Procedures. Pinnacle will provide to
Northwest the following fuel administrative service assistance: (i) timely Fuel

                                                                    Page 6 of 19
                                                 (as amended by Amendment No. 3)

Management System ("FMS") data entry by Pinnacle at Pinnacle Service Cities
including month-end reconciling to the fixed base operator ("FBO") by the end of
the second business day, (ii) FMS coverage by Pinnacle when regular FMS person
is on vacation, leave, etc., (iii) Pinnacle will train new Pinnacle employees on
FMS due to turnover, vacation, etc., (iv) problems at FBO regarding supply of
fuel slips and bill of lading receipts will be addressed by Pinnacle personnel
first before involving the Northwest Fuel Department.

                  (e) Fuel Burn Review Procedures - CRJ. Northwest and Pinnacle
agree to review the fuel burn performance of the CRJ Aircraft for compliance
with the performance measure (burn rate ceiling) set below. Either party may
initiate the audit of the actual fuel burn against the set measure. The
performance measure includes both scheduled and non-scheduled fuel
usage/expense. The ceiling is the Northwest budgeted scheduled fuel burn per
scheduled Block Hour plus 3% for non-scheduled usage. For example, the 2002
performance measure (ceiling) was equal to the Northwest scheduled fuel burn
rate of 308.6 gallons per scheduled Block Hour plus 3%, which sets the ceiling
at 317.9.

                  In the event that the CRJ Aircraft's actual fuel burn for the
period of review is above the ceiling the parties will work together in good
faith to explain the variance relative to the ceiling and to resolve the cause
of the variance. If it is determined that actual fuel burn was above the ceiling
for reasons within the control of Pinnacle, Pinnacle will pay a Fuel Burn
Penalty Payment to Northwest and such payment shall be made in accordance with
Section 5.07. The Fuel Burn Penalty Payment shall be calculated as follows:

                  Fuel Burn Penalty Payment = [(total fuel expense/actual fuel
price) / scheduled Block Hours - performance ceiling] * completed scheduled
Block Hours * actual fuel price (not to exceed $.78 per gallon) + Margin
applicable to the fuel expense reimbursement pursuant to Section 5.08 or 5.11.

                  SECTION 5.06 DIRECT EXPENSES. Northwest will reimburse
Pinnacle for the following expenses at the Direct Cost to Pinnacle.
Reimbursement for these expenses paid or accrued by Pinnacle in the prior month,
(other than the Equipment Rental Expense) will be included in the wire transfer
to Pinnacle on the 15th of each subsequent month pursuant to Section 5.02(b)
above. The reimbursement of Equipment Rental Expense pursuant to Section 5.06(a)
attributable to a month will occur as part of the provisional payment on the
30th of such month pursuant to Section 5.02(b). Pinnacle will be responsible for
providing Northwest with a copy of all third party invoices and evidence of
payment needed to determine the expense amount and the timeliness of payment.

                  (a) Equipment Rental Expense - less any performance guarantee
payments or credits that Pinnacle receives from the manufacturers.

                  (b) Aviation Insurance - Aircraft hull insurance and aviation
liability insurance, including war risk liability and hull war risk insurance,
subject to the following:

                  Pinnacle's aviation liability insurance (including war risk
liability) expense shall be the lesser of the expense based on the actual rates
or $1.69 per Pinnacle Revenue Passenger. Pinnacle's hull insurance (including
hull war risk insurance) expense shall be the lesser of the expense based on the
actual rates or $0.00165 per dollar ($) of Pinnacle Fleet Value. The margin
payment pursuant to Section 5.08 or 5.11 shall be based on the foregoing
amounts. If Pinnacle's actual aviation insurance expense exceeds the amounts
above, the incremental insurance expense above the foregoing limits will be
reimbursed by Northwest. In the event that Pinnacle obtains aviation insurance
coverage as part of Northwest's aviation insurance placement, the rates used to
determine Pinnacle's share of the aviation insurance expenses shall be the same
as the rates used to determine Northwest's expense for such insurance.

                  (c) Engine maintenance - The CRJ 200/440 engine maintenance
performed pursuant to the GE Agreements less any warranty payments or credits
that Pinnacle receives, including but not limited to those from GE, plus the
cost of materials and components used in connection with unscheduled off-wing
maintenance performed by Pinnacle (not including maintenance or replacement of
line replaceable units or QEC items). Pinnacle shall provide to Northwest, upon
reasonable request, documentation detailing the unscheduled event and cost of
each of the components. If Northwest and Pinnacle agree at any time to have such
engine work performed elsewhere, the reimbursement amount will be adjusted to
take into account the new arrangement. Notwithstanding the foregoing, Northwest
will not reimburse Pinnacle for engine maintenance performed pursuant to the GE
Agreements which is accomplished unreasonably in advance of the time such
maintenance is required in accordance with the Maintenance Program or which is
accomplished for the sole purpose of satisfying return conditions under the
Lease.

                  (d) Airframe maintenance - The CRJ 200/440 airframe
maintenance performed pursuant to Bombardier Agreement less any warranty
payments or credits that Pinnacle receives, including but not limited to those
from Bombardier. If Northwest and Pinnacle agree at any time to have the

to take into account the new arrangement. Notwithstanding the foregoing,
Northwest will not reimburse Pinnacle for airframe maintenance performed
pursuant to the Bombardier Agreement which is accomplished unreasonably in
advance of the time such maintenance is required in accordance with the
Maintenance Program or which is accomplished for the sole purpose of satisfying
return conditions under the Lease.

         less the amounts of any refunds, subject to the provisions of Section
         8.04.

Notwithstanding the foregoing, Northwest will not reimburse Pinnacle for any
late payment charges, penalties and/or fees which Pinnacle incurs in connection
with payment of the expenses listed above.

                  SECTION 5.07 BILLING. Northwest and Pinnacle shall bill each
other on a monthly basis in respect of amounts owed to each other under this
Agreement not contemplated under Section 5.02. If such billed items are not paid
by the party within sixty (60) days of the statement date, the aggregate amount
of undisputed items may be offset against or included in the next scheduled wire
transfer pursuant to Section 5.02(b). Disputed amounts must be paid when the
dispute is resolved, provided that such amount may be set off against or
included in the next scheduled wire transfer pursuant to Section 5.02(b) if the
formerly disputed amount is not paid within seven (7) days of resolution.
Northwest may also offset against the next scheduled wire transfer pursuant to
Section 5.02(b) the amount of any payment (including those under any Lease or
the Note) with respect to which Pinnacle shall have defaulted and shall have
failed to cure before the expiration of any applicable grace period.

period through December 31, 2007, the parties will calculate Pinnacle's Margin
in accordance with Section 5.09(a) and, if required pursuant to Section 5.09(b)
below, one party will make a Margin Adjustment Payment to the other party.

                    (a) Calculation of the Total Operating Cost and the Margin.
Not later than ninety (90) days following the end of 2003, 2004, 2005, 2006 and
2007, Pinnacle shall deliver to Northwest its audited financial statements
including the calculation of its operating margin for Regional Airline Services
provided under this Agreement for the prior year (the "Margin") by dividing (x)
Pinnacle's Total Operating Income for Regional Airline Services for such year by
(y) Pinnacle's Total Operating Revenue for Regional Airline Services for such
year, subject to the following:

                  In calculating the Margin, the amount of any penalties
(accounted for as a reduction to revenue) pursuant to Section 5.05, Section 5.13
and/or Section 5.14 below and any Saab 340 Aircraft rental revenue will not be

         fees incurred by Pinnacle.

                  (11) The amount of any payment from Pinnacle to Northwest
         pursuant to Section 5.13 (if not accounted for as a reduction to
         revenue).

                  The Margin shall be expressed as a decimal rounded to the
fourth place. The calculation of the Margin shall be derived from Pinnacle's
reported financial statements for such year and shall be determined in
accordance with GAAP.

                  (b) Annual Margin Adjustment Payment. With respect to each
calendar year through and including 2007, the Margin will be subject to the
floors and ceilings in the following table:

With respect to each calendar year through and including 2007, if the Margin is
greater than the applicable Ceiling, Northwest shall receive from Pinnacle an
amount determined as follows:

                  Pnw = Rev - [Total Operating Cost/(1 - Ceiling)]

                  where,

                  Pnw is the amount payable to Northwest,
                  Rev is Total Operating Revenue for Regional Airline Services
                  for the applicable calendar year excluding the items listed in
                  Section 5.09 (a),

                  Ceiling is the applicable ceiling from the above table, and

                  Total Operating Cost excludes items 1-11 in Section 5.09(a)
                  above.

An amount payable pursuant to this Section 5.09 (b) is a "Margin Adjustment
Payment." Northwest shall add in or setoff, as appropriate, any Margin
Adjustment Payment in the next wire transfer due to Pinnacle.

                  (c) Audit of Total Operating Cost and the Margin. Northwest
shall have the right to audit the calculation of the Total Operating Cost, the
Margin and the Margin Adjustment Payment, and shall report any disputes to
Pinnacle. Any dispute not reported to Pinnacle in writing within ninety (90)
days of the receipt of the audited financial statements and Margin calculation
by Northwest shall be deemed waived. The payment in respect of any dispute shall
be handled as a disputed amount in accordance with Section 5.07.

                  SECTION 5.10  RATE ADJUSTMENTS.  For the calendar year 2006,
the Block Hour, Cycle, and Fixed Cost Rates will be adjusted as described below.

                  (a) One Time Adjustment Factor. Effective for the twelve-month
period beginning on January 1, 2006 (i) the Block Hour Rate used for the 2005
calendar year will be multiplied by a One Time Adjustment Factor (OTAF) and
multiplied by (1 + CPPI), and (ii) the Cycle Rates shall be calculated by
multiplying the Base Cycle Rates for 2005 by (1 + CPPIB)* (OTAF). These adjusted
rates will be used for the twelve-month period beginning January 1, 2006. The
OTAF will be calculated as follows:

                           (1) Determine Pinnacle's actual operating expenses
                  for the twelve-month period ending December 31, 2005,
                  excluding expenses defined in Section 5.05 (fuel expenses),
                  expenses defined in Section 5.06 (direct expenses), the
                  expenses excluded from the Margin calculation in Section
                  5.09(a), and any expenses deemed non-recurring by Northwest.

                           (2) Determine the actual payment made to Pinnacle for
                  the twelve month period ending December 31, 2005, excluding
                  the Monthly

                                                                   Page 12 of 19
                                                 (as amended by Amendment No. 3)

                  Margin Payment (Section 5.08), any Margin Adjustment Payments
                  (Section 5.09), and any payments pursuant to Sections 5.05 and
                  5.06.

                           (3) Divide the result of step (1) by the result of
                  step (2).

                  (b) Inflation Adjustment. Effective for 2007, (i) the Block
Hour Rate used for 2006 will be multiplied by (1+CPPI), and (ii) the Cycle Rates
shall be calculated by multiplying the Base Cycle Rates used for 2006 by (1 +
CPPI), to establish the 2007 rates.

                  (c)  Fixed Cost Payment Adjustment. Effective for 2006 and
2007, the Fixed Cost Payment formula will be multiplied by the OTAF.

                  (d) Effective for 2008 the payment rates and mechanisms set
forth in Sections 5.02 through 5.06 will be re-set through good faith
negotiations utilizing a payment methodology consistent with the methodology
utilized through 2007; provided, however, that any increment above market pay
rates for Pinnacle's employees, per the Parity Pay Agreement in Exhibit D, will
not be considered in re-setting such rates. The rates for 2009, 2010, 2011 and
2012 will be determined by multiplying the prior year's rates by (1+CPPI).

                  (e) So long as this Agreement remains in effect, the payment
rates and mechanisms set forth in Sections 5.02 through 5.06 will be re-set
every fifth year through good faith negotiations, commencing with the rates
effective for 2013, utilizing a payment methodology consistent with the
methodology utilized during the prior five (5) year period; provided, however,
that any increment above market pay rates for Pinnacle's employees, per the
Parity Pay Agreement in Exhibit D, will not be considered in re-setting such
rates. The rates for the years between each adjustment year will be determined
by multiplying the prior year's rates by (1 + CPPI).

                  (f) In the event the parties are unable to reach agreement on
new payment rates and mechanisms through good faith negotiations, the rates will
be set utilizing the following procedure: (i) the parties shall attempt to agree
upon an impartial industry expert to act as sole arbitrator, provided that if
the parties are unable to agree upon an expert to so act, each party shall
appoint an expert, and the two experts so appointed shall appoint a third
expert; (ii) each party shall submit a set of proposed rates to the
arbitrator(s); and (iii) the arbitrator(s) shall choose a set of rates from
those submitted without modifying either.

                  SECTION 5.11  REVISED MONTHLY MARGIN CALCULATION AND PAYMENT.
Effective January 1, 2008, the monthly Margin Payment shall be calculated as
follows:

                  Monthly Margin Payment = (payments due to Pinnacle pursuant to
                  Sections 5.03, 5.04, 5.05 and 5.06 (all adjusted pursuant to
                  Section 5.10)) * MMR / (1-MMR)



Exhibit I

                                                                       Article V
                                                                   Page 13 of 19
                                                 (as amended by Amendment No. 3)

                  Where, MMR is the Market Margin Rate.

                  SECTION 5.12 REVISED ANNUAL MARGIN ADJUSTMENT PAYMENT.
Effective for 2008 and each calendar year thereafter, the parties will calculate
Pinnacle's Margin in accordance with Section 5.12(a) and, if required pursuant
to Section 5.12(b) below, one party will make a Margin Adjustment Payment to the
other party.

                  (a) Calculation of the Total Operating Cost and the Margin.
Not later than ninety (90) days following the end of 2008 and each subsequent
calendar year during the term of this Agreement, Pinnacle shall deliver to
Northwest its audited financial statements including the calculation of its
operating margin for Regional Airline Services provided under this Agreement for
the prior year (the "Margin") by dividing (x) Pinnacle's Total Operating Income
for Regional Airline Services for such year by (y) Pinnacle's Total Operating
Revenue for Regional Airline Services for such year, subject to the following:

                  In calculating the Margin, the amount of any penalties
(accounted for as a reduction to revenue) pursuant to Section 5.05, Section 5.13
and/or Section 5.14 below and any Saab 340 Aircraft rental revenue will not be
included in Pinnacle's Total Operating Revenue, and the following expenses will
not be included in Pinnacle's Total Operating Cost:

                  (1) Increment above predicted employee bonuses and incentives
         as set forth in Exhibit C hereto. Predicted bonus and incentive levels
         are the amounts used in calculating the Block Hour, Cycle and Fixed
         cost rates for 2007, grown each year by multiplying by (1 + CPPI).

                  (2) The amount of any penalties pursuant to Section 5.14 (if
         not accounted for as a reduction to revenue).

                  (3) The amount of any depreciation expense associated with
         capital expenditures in excess of $250,000 which are designated by
         Northwest as Section 5.13(a)(3) items because Northwest has determined
         that such capital expenditures are not necessary after taking into
         consideration the Annual Operating Plan and Pinnacle's obligations
         under this Agreement, within seventy-five (75) days after receiving
         written notice from Pinnacle of such capital expenditure pursuant to
         Section 6.01(a)(iv) below.

                  (4) The amount of any Fuel Burn Penalty Payment pursuant to
         Section 5.05(d) (if not accounted for as a reduction to revenue).

                  (5) The amount of any asset write-downs (excluding normal
         depreciation) or extraordinary charges as defined by GAAP.

                  (6) Rental expense associated with the Saab 340 Aircraft not
         flown by Pinnacle.

                  (7) The amount of any fines or penalties paid by Pinnacle to
         any governmental entity.

                  (8) The CRJ 200/440 Aircraft and Spare Engine return costs
         including termination costs incurred by Pinnacle pursuant to Section
         3.02 (b) above.

                  (9) The amount of any late payment charges, penalties and/or
         fees incurred by Pinnacle.

                  (10) The amount of any payment from Pinnacle to Northwest
         pursuant to Section 5.13 (if not accounted for as a reduction to
         revenue).

                  The Margin shall be expressed as a decimal rounded to the
fourth place. The calculation of the Margin shall be derived from Pinnacle's
reported financial statements for such year and shall be determined in
accordance with GAAP.

                  (b)      Annual Adjustment to Margin Payment.

                  With respect to each calendar year effective 2008, if the
Margin is greater than MMR but less than or equal to (MMR + 0.05), Northwest
shall receive from Pinnacle an amount determined as follows:

                  Pnw = (Rev - [Total Operating Cost/(1 - MMR)]) / 2

                  where,

                  Pnw is the amount payable to Northwest,

                  Rev is Total Operating Revenue for Regional Airline Services
                  for the applicable calendar year excluding the items listed in
                  Section 5.12 (a), and

                  Total Operating Cost excludes items 1-10 in Section 5.12(a)
                  above.

                  With respect to each calendar year effective 2008, if the
Margin is greater than (MMR + 0.05), Northwest shall receive from Pinnacle an
amount determined as follows:

                  Pnw = (Rev - [Total Operating Cost/(0.975 - MMR)])

                  where,

                  Pnw is the amount payable to Northwest,

                  Section 5.12 (a), and

                  Total Operating Cost excludes items 1-10 in Section 5.12(a)
                  above.

                  An amount payable pursuant to this Section 5.12(b) is a
"Margin Adjustment Payment." Northwest shall add in or setoff, as appropriate,
any Margin Adjustment Payment in the next wire transfer due to Pinnacle.

                  (c) Audit of Total Operating Cost and the Margin. Northwest
shall have the right to audit the calculation of the Total Operating Cost, the
Margin and the Margin Adjustment Payment, and shall report any disputes to
Pinnacle. Any dispute not reported to Pinnacle in writing within ninety (90)
days of the receipt of the audited financial statements and Margin calculation
by Northwest shall be deemed waived. The payment in respect of any dispute shall
be handled as a disputed amount in accordance with Section 5.07.

                  SECTION 5.13      NON-SCHEDULED FLIGHT REFUND.

                  With respect to each calendar year during the term of this
Agreement, Northwest shall within thirty (30) days from the receipt of the final
Block Hour and Cycle Report received pursuant to Section 5.02 for the
immediately preceding year, calculate and notify Pinnacle of the ratio of actual
Block Hours for Non-Scheduled Flights to actual Block Hours for Scheduled
Flights and the ratio of actual Cycles for Non-Scheduled Flights to actual
Cycles for Scheduled Flights. In the event that either ratio exceeds .25%
(.0025), Pinnacle shall remit to Northwest (through a set-off of the next amount
due from the Section 5.02 wire transfer) an amount equal to the following:

         Refund Calculation:
         ------------------

         Actual Block Hours and/or Cycles for Non-Scheduled Flights in excess of
         .25% (.0025) of the actual Block Hours and Cycles for Scheduled
         Flights, respectively, multiplied by the Block Hour Rate and Cycle
         Rate, respectively, in effect for the immediately preceding year
         pursuant to Section 5.03 and as adjusted pursuant to Section 5.10, plus
         the amount of any Margin Payments previously paid by Northwest to
         Pinnacle in connection with such excess Block Hours and/or Cycles;
         provided, however, that no refund will be paid to Northwest with
         respect to Non-Scheduled Flights which are Aircraft delivery flights.
         For purposes of this calculation, the cycle rate used will be the
         average of the then applicable Cycle Rates weighted by the number of
         Cycles in each category in Section 5.03(b).
