 SCOPE OF SERVICES 

Inventory Maintenance; Basis for Provisioning 

Delta will maintain an inventory of Components to support the Aircraft within the program performance measures as more fully defined in the
paragraph below entitled “Performance Measures”. Delta intends to provide Component support to the Aircraft which shall include maintaining a supply and inventory management and tracking function for Components, and providing Components to
MN Airlines on an exchange basis, as described below. The Components used to Support Aircraft shall be integrated into Delta’s existing inventory for use on both Delta aircraft and MN Airlines’s Aircraft. 

Supply Response Times 
 When a
Component requires removal from an Aircraft and MN Airlines does not have a replacement Component available, MN Airlines will notify Delta Front Desk and, within thirty minutes of receiving any such notice, Delta will: (i) acknowledge receipt
of the request; (ii) advise MN Airlines whether a replacement Component is in stock or must be obtained from another source; and (iii) either give MN Airlines complete shipping information for the replacement Component or advise MN
Airlines of when such information will become available. Delta will ship a Component to MN Airlines’ home base at MSP as soon as possible; but in any event, to comply with program performance measures, all Components will be shipped within
twenty-four (24) hours of Delta’s receipt of a request at least ninety percent (90%) of the time in the case of Airframe and Engine Components and APU Components. Such percentages will be calculated on twelve-month rolling averages. If
either such rolling average falls below the program performance measures, Delta and MN Airlineswill identify the reasons for the program performance shortfall. Upon such identification, Delta and MN Airlines will take prompt action to ensure that
the Components arc either stocked or sourced in sufficient quantities to meet the program performance measures stated in this Annex. Notwithstanding the preceding sentences, Delta will ship Components using the same degree of expediency for a MN
Airlines AOG situation that Delta generally uses for a Delta AOG situation. If Delta’s general AOG handling methods arc not sufficient in a particular situation, then at Sun Country’s request, Delta will arrange for unique shipping
methods, such as the hiring of private aircraft to ship the Component, all at MN Airlines’ cost and expense. 
 If a Common Component
can not be provided to MN Airlines in accordance with the program performance measures and Sun Country has an Aircraft that is AOG for such Component, and Delta is not currently in compliance with the twelve-month rolling average for performance
measures, Delta will provide a credit to MN Airlines against future services, for an amount equal to the substantiated loan charges incurred by MN Airlines for the loan of a No Go Component when such No Go Component can not be provided by Delta to
MN Airlines at a Common Station and MN Airlines has an Aircraft that is unable to complete a scheduled revenue flight due to the lack of such No Go Component. Delta’s obligation for such loan borrow charges shall only be for the time period
such component was unavailable from Delta and only for the actual components required to satisfy the AOG requirement. 

  
 15 

 MN Airlines Inventory Support Agreement 8 Oct 2003 

 

 Configuration Management 

Delta shall have configuration management responsibility for Components. MN Airlines shall cooperate with Delta to ensure that Component
configuration is maintained in accordance with FAA regulatory requirements. 
 Reliability Monitoring & Tracking 

Delta shall provide to MN Airlines, an Unscheduled Removal report for Components as removed from Delta’s
737-NG aircraft. This report shall be provided quarterly to aid in monitoring Component reliability trends, and failures. MN Airlines shall provide to Delta, an Unscheduled Removal report for Components
removed from Aircraft. This report shall be provided quarterly to aid in monitoring Component reliability trends, and failures. 
 Delta
will utilize its existing reliability tracking program to track Components operated on Delta aircraft only. The systems to be tracked, the calculations to be made and the performance standards against which the systems arc measured will be in
accordance with Delta’s reliability program requirements. Data required to support such a tracking program will be supplied to Delta by MN Airlines as requested by Delta. MN Airlines will co-operate with
Delta to further develop acceptable data models and methods of data transmission. For Components operating on Delta aircraft, Delta will periodically review the trend analysis and implement corrective action if reliability falls below Delta’s
established statistical limits. Delta will not track the reliability of Components operating on MN Airlines Aircraft. MN Airlines will utilize its existing reliability tracking program to track Components operated on MN Airlines. The systems to be
tracked, the calculations to be made and the performance standards against which the systems are measured will be in accordance with MN Airlines’ reliability program requirements. For Components operating on MN Airlines Aircraft, MN Airlines
and Delta will periodically review the trend analysis and implement corrective action if reliability falls below Delta’s established statistical limits. 

Inventory Management 
 Delta shall
utilize its existing inventory management system to manage, order, and track Components. 
 Maintenance and Repair 

Delta will maintain the Components in accordance with current manufacturer’s standard practice and component maintenance manuals and
Delta’s continuous airworthiness maintenance program. Each Component shipped by Delta will have attached to it a Delta Air Lines approved return to service tag (e.g. 8130, Pick List, Pass Parts Tag) indicating that the Component is airworthy
with respect to the work performed. 
 Misuse or Abuse of Components 

Repair and replacement of Components damaged due to MN Airlines’ use of such Components outside of the manufacturer’s
recommendations, improper operation/maintenance, consequential damage, foreign object damage, abuse, negligence or accidental damage shall be repaired by Delta at Delta T&M Rates, or if replacement is necessary, shall be replaced at the then
current manufacturer’s list price. Delta shall bear all costs for the replacement of all Components deemed beyond economic repair (BER) due to normal wear and tear. 

  
 16 

 MN Airlines Inventory Support Agreement 8 Oct 2003 

 

 No Fault Found (NFF) Components 

For all Components returned to Delta for Service under the PBTH Rate, if Delta cannot confirm a failure of such Component after inspection or
testing, or such inspection or testing shows the Component to be in serviceable condition (“NFF”), then Delta will notify and provide inspection and testing results to MN Airlines. For NFF Components, MN Airlines will pay to Delta, $500
for testing and recertification of NFF Component(s). If testing and recertification is accomplished by a Delta vendor, MN Airlines will pay Delta’s substantiated cost plus eight percent (8%). The preceding notwithstanding, MN Airlines will not
be charged a NFF fee if the removal of the Component was based on a troubleshooting recommendation by Delta that such Component be removed. For Delta tested and re-certified NFF Component(s), if such
Component(s) is subsequently removed with a confirmed failure within one hundred (100) Flight Hours of installation for the same reason as identified on the prior removal, then Delta will repair such Component and, in addition, will either:
(i) issue MN Airlines a credit against an unpaid Delta invoice issued for a NFF charge, or (ii) credit to MN Airlines the amount paid by MN Airlines for the NFF charge. 

Airworthiness Directives (ADs). 

Delta will, as part of the Services, review, analyze and issue engineering documentation for the incorporation of Airworthiness Directives (AD)
into Components. The actual accomplishment of any AD on Components will be charged to MN Airlines at Delta Time & Material Rates. For Components, only the amount of such Components delivered with MN Airlines’ Aircraft that did not
comply with the particular AD shall be charged for AD incorporation. The amount of labor charged for accomplishing any AD will be those number of man-hours specified in the AD, or if the AD fails to specify
the number of man-hours, then such information will be obtained from the relevant equipment manufacturer. If the manufacturer specifics the number of man-hours, then not
more than such number will be invoiced by Delta. If the manufacturer docs not supply such information, Delta will estimate the labor required to accomplish the AD and notify MN Airlines. Delta will track and invoice MN Airlines for the actual labor
necessary to accomplish the AD, advising of any substantive changes, if they occur, that would significantly alter the estimate. Any labor expended on Services not required to accomplish the AD will be allocated as appropriate either to the PBTH
Rate or to the Delta Time & Material Rate as provided elsewhere herein. The material part of the Delta Time & Material Rate charge will be for only that material necessary to complete the AD per the information in the AD. If the AD
fails to provide the list of materials necessary to accomplish the AD, such information will be obtained from the relevant equipment manufacturer. If that information is not available, Delta will estimate the material required to accomplish the AD.
Delta will track and invoice for the actual material necessary to accomplish the AD. If the only reason for removing a Component from an Aircraft was to accomplish an AD, Delta will invoice for, and MN Airlines will pay to Delta, all the costs
required for the Services associated with the accomplishment of the AD and other Services required by the Maintenance Program to return the Component to serviceable condition at Delta Time & Material Rates. Any other work performed during
such a shop visit to enhance any performance or life of the Component will be borne by Delta. To the extent allowed by the time limits of the AD, Delta will make all reasonable efforts to accomplish ADs in conjunction with other scheduled
maintenance on such Component. 
 Service Bulletins (SBs) 

As deemed necessary by Delta, Delta will from time to time, as part of the Services, review, analyze and issue engineering documentation for
the incorporation of SBs into Components. For 

  
 17 

 MN Airlines Inventory Support Agreement 8 Oct 2003 

 

 
Components requiring incorporation of a SB to meet Delta modification standard, Delta will incorporate that SB at the time Delta performs other Services on such Components, in accordance with the
following: 
 SBs Costing No More Than $1,200 

If Delta reasonably estimates the incorporation of an SB into a Component will cost no more than $1,200, when calculated at Delta
Time & Material Rates, then such SB will be incorporated into the Component as part of the Services provided under the PBTH Rate. Such SB may be automatically incorporated without MN Airlines permission so long as MN Airlines is provided
with notice and the SB does not change the fit, form or function of the Component. In the event the SB will change the fit, form or function of the Component, then Delta shall provide MN Airlines with a written copy of Delta Engineering Order (EO)
for such change. 
 SBs Costing More than $1,200 

If Delta reasonably estimates the incorporation of an SB into a Component will cost more than $1,200, when calculated at Delta Time &
Material Rates, then such SB will be incorporated at MN Airlines’s expense at Delta Time & Material Rates, but only for the number of such Components delivered with MN Airlines’s Aircraft that do not have the particular SB
incorporated. In the event that the Component manufacturer or some other person compensates Delta for the incorporation of the SB, then MN Airlines shall not be charged to the extent such compensation reduces Delta’s cost for incorporating the
SB below $1,200. 
 Determining the Cost of SBs 

The determination of the time and material elements of Delta Time & Material Rates for incorporation of SBs provided for above will be
calculated in accordance with this Section. The markup on materials will be based on the current list price. The labor part of the Delta Time & Material Rate charge will be only for that number of
man-hours specified in the SB, or if the SB fails to specify the number of man-hours, then such information will be obtained from the relevant equipment manufacturer. If
the manufacturer specifies the number of man-hours, then not more than such number will be invoiced by Delta. If the manufacturer does not supply such information, Delta will estimate the labor required to
accomplish the SB and notify MN Airlines. Delta will track and invoice for the actual labor necessary to accomplish the SB, advising of any substantive changes if they occur that would significantly alter the estimate. The material part of the Delta
Time & Material Rate charges will be for only that material necessary to complete the SB per the information in the respective SB. If the SB fails to provide the list of material necessary for accomplishment of the SB, such information will
be obtained from the appropriate equipment manufacturer. Using the bill of material specified either in the SB or by the manufacturer, Delta will flat-rate the material for the SB at the then-current prices. If that information is not available,
Delta will estimate the material required to accomplish the SB. Delta will track and invoice for the actual material necessary to accomplish the SB. Labor expended on Services not required by the accomplishment will be allocated as appropriate
either to the PBTH Rate or the Delta Time & Material Rate as provided elsewhere herein. If the only reason for removing a Component from an Aircraft is to accomplish the performance of an SB, Delta will invoice for, and MN Airlines will pay
to Delta, all the costs required for the Services associated with the accomplishment of the SB and other Services required to return the Component to serviceable condition at Delta Time & Material Rates. 

Modification Compatibility 
 If MN
Airlines chooses not to accept a Component modification that Delta is performing on Components for Delta’s fleet and such decision causes such Component to become a NonCommon Component, MN Airlines agrees to amend this Agreement to remove such
Component from the support obligations of this Agreement. 

  
 18 

 MN Airlines Inventory Support Agreement 8 Oct 2003 

 

 MN Airlines, at its’ own cost and expense, will create or revise all MN Airlines
documentation and equipment, including task cards, Illustrated Parts Catalogs, test equipment and Aircraft, that are affected or necessitated by all such EOs, ADs, and SBs related to Common Components. 

Undocumented Components or Repairs 

If, in performing any Services, Delta finds any undocumented Component or repair, then Delta will promptly notify MN Airlines along with
providing documentation of the undocumented Component and/or repair. MN Airlines shall then substantiate such Component within three (3) Business Days of Delta’s notice. If MN Airlines is unable to substantiate such Component, Delta will
not accept the undocumented Component for Services or remedy the undocumented repair at Delta Time & Material Rates. 
 Return of Components

 MN Airlines will return each Component removed from an Aircraft accompanied by all required data to Delta’s Technical
Operations Facility at 1775 Aviation Boulevard or other such facility as directed by Delta Front Desk within five (5) Days of receipt of requested serviceable Component. MN Airlines will arrange for all such shipments except in those instances
when Delta or a Delta subcontractor actually removes and replaces an Component. In such instances within the United States, Delta will pack, ship and track shipment of such Component. In such instances outside the United States, MN Airlines’
maintenance control center will be responsible for coordinating the return of the unserviceable Component. 
 Shipment Methods and Costs; Packing;
Required Records 
 Method of Shipment and Costs. 

For any Component which requires Services, MN Airlines will provide for shipment of such Component at its own cost and expense via any
reasonable method that will meet the Component return time requirement. 
 Proper Packaging. 

Delta will normally deliver all serviceable Components in reusable Category l containers (as defined in ATA Specification 300). MN Airlines
will return each removed Component in the same or equivalent container as the one in which the replacement was shipped. If that container or its equivalent is not returned to Delta, MN Airlines will be charged for its replacement. Each Component
shipped by Delta will have attached to it a tag indicating serviceability under the standards of FAR Part 121. Regardless of the method of shipment, MN Airlines shall be responsible for ensuring that Components arc properly prepared, packaged,
labeled and documented under applicable ATA 300 and hazardous goods regulations. In the event Delta receives a Component from MN Airlines that is not properly packaged under applicable ATA 300 and hazardous goods regulations, Delta will so notify MN
Airlines in order for MN Airlines to provide a proper package for use by Delta in returning the Component to MN Airlines. In the event MN Airlines fails to provide the proper packaging, Delta may provide such packaging required under the applicable
ATA 300 and hazardous good regulations and MN Airlines shall compensate Delta for such packaging at Delta Time & Material Rates.

ln order for a Component to be accepted for Service by Delta, MN Airlines will furnish the following data with each Component offered for
Services: the Aircraft’s registration and serial number that the Component was removed from; the Component name, model, and serial number; the number of Flight Hours and cycles the Component accumulated on the Aircraft; the dates the Component
was installed and removed, and the reason for removal. Concurrent with shipment of serviceable Components Delta will provide data on each such Component, including, as available, aggregate flight hours and cycles accumulated, serial number, the
Component name, model and serial number; the total number of hours and cycles on the Component. 
 At end of Term or in case of early
termination, MN Airlines shall provide Delta with a written list, by serial number, part number, and nomenclature, of Components eligible for Service that arc installed on MN Airlines Aircraft. Upon receipt of such written list, Delta shall provide
MN Airlines with all available records for such Components. 
 Warranty Administration 

On behalf of MN Airlines, Delta will administer all claims against manufacturers of removed Components on which a warranty is in effect. Delta
will retain any and all warranty related compensation. To achieve this purpose, MN Airlines will cause the assignment to Delta of all warranty rights related to the Components. If MN Airlines has not made reasonable efforts for such assignment
before a warranted Component must be repaired, MN Airlines will be charged for such repair at T&M. All assignments of warranty rights to Delta pursuant to this Section will expire immediately upon termination or expiration of this Agreement and
such rights will revert to MN Airlines. 
 Project Manager; Customer Representatives 

Delta will assign an employee with experience in project management to coordinate all aspects of the Services and to be the primary liaison
with MN Airlines during the term of the Agreement. MN Airlines will designate one or more representatives who at all times during the term of this Agreement will have the authority to accept or reject work performed by Delta. MN Airlines will
furnish to Delta’s Project Manager a list of its personnel, with contact information, who are responsible for the subjects covered by this Agreement. Delta will furnish to MN Airlines a list of its personnel, with contact information, who are

 MN Airlines Inventory Support Agreement 8 Oct 2003 

 

 ANNEX A2 

Charges & Payments 

Component Access and Exchange - Flat Rate per Aircraft 

Delta will charge MN Airlines and MN Airlines will pay to Delta a flat monthly fee for Component access and exchange to include support at
Common Stations. Such fee will be computed monthly by multiplying the number of aircraft covered under this Agreement times a flat fee of $7,500.00 USD per aircraft. Such payment will be made in accordance with Section 3.2. The rate for
Component access and exchange will be calculated on the last day of each month. For Aircraft introduced into or removed from MN Airlines’ fleet during any particular month, the number of Aircraft considered in operation for that particular
month shall be pro-rated based on the percentage of days that month such Aircraft has spent in service. Use of an Aircraft for any portion of a calendar day, local Aircraft time, constitutes use of the
Aircraft for that day, for purposes of this section. The Aircraft is considered used if it is operated for any purpose, whether revenue, charter, training, promotional or non-revenue flying. 

Component Repair & Management - Cost per Flight Hour & Rate Adjustment 

MN Airlines will pay to Delta, as compensation for Services which are described herein, as being provided on a
power-by-the-hour basis for each calendar month until the expiration or termination of this Agreement, an amount equal to the
product of the Power-by-the-Hour (PBTH) Rate times the total number of Flight Hours for all Aircraft during such month. The CY
2003 PBTH Rate shall be as shown in the table below and such rate is subject to an annual escalation as provided in Annex A3 of this Agreement. MN Airlines will report to Delta by no later than the third business day of each month the total number
of Flight Hours for all Aircraft for the preceding month. MN Airlines will allow Delta representatives to inspect its operating records with respect to the Aircraft to verify the accuracy of the Flight Hour information. The PBTH rate for each
Aircraft shall be adjusted based on the age of the aircraft as follows: 
  

					
	 Aircraft Age,
 months from

OEM delivery
	  	PBTH
Rate	 
	 0 to 36
	  	$	55	 
	 37 to 60
	  	$	115	 
	 >60
	  	$	150	 

 Delta reserves the right to amend the rates specified above in the event of unusual circumstances surrounding Aircraft
introduced into this Agreement after the Effective Date. In addition, should Delta and MN enter into an agreement for the provisioning of engine maintenance services on MN’s cfm56-7 aircraft engines by
Delta on an exclusive basis, Delta will, in good faith, re-evaluate the above rate in an effort to provide MN with a more favorable rate. 

  
 22

 Time & Material Rates (Delta T&M) 

MN Airlines will pay Delta for Services performed on a Delta Time & Material Rate basis at the following rates: 

 

	 	•	 	 $72.00 per hour for mechanics and inspectors.* 

 

	 	•	 	 $115.00 per hour for engineers and analysts. * 

 

	 	•	 	 New material at Delta’s cost plus twelve (12) percent with a per item cap on the markup of $1,250.00
and a per line item cap on the markup of $2,500.00* 

  

	 	•	 	 Used/serviceable material at 75% of manufacturer’s then-current list price with no markup.

  

	 	•	 	 MN Airlines-supplied parts at 5% of MN Airlines’s cost up to a maximum of $250.00 No-charge parts or kits would not be subject to this handling fee.* 

  

	 	•	 	 Outside repair at Delta’s invoiced cost plus 8%. 

 

	 	•	 	 Consumable miscellaneous shop supplies will be provided at no charge. 

 

	*	 These labor and material items will be escalated in accordance with Delta Time & Material Rate
Escalation Formula Section of Annex A3. 

 Late Charges 

For every day beyond the fifth Day that MN Airlines retains a removed Component or fails to provide the required data for such Component, Delta
will charge MN Airlines a daily fee representing a percentage of the manufacturer’s current list price, computed cumulatively as follows: (i) 1.5% per day for days 5 through 10, then: (ii) 2% per day for days 11 through 20, then; (iii) 3%
per day for days 21 through 30, then; (iv) 4% per day from days 31 through 45 or until return. After day 45 the component will be considered lost and MN Airlines will be invoiced for all accumulated late charges and OEM current list price or
Delta’s actual replacement cost, whichever is greater. 
 Time & Material Invoices 

Delta will issue to MN Airlines at least monthly, or on a project basis, an invoice setting forth the Delta Time & Material Rate
charges for Services not covered by the PBTH Rate. Such invoices will be addressed and sent to MN Airlines at the following address:

 MN Airlines Inventory Support Agreement 8 Oct 2003 

 

 ANNEX A3 

Rate Escalation Formulas and Adjustments 

Power-by-the-Hour Rate Escalation
Formulae 
 All rates contained in this agreement will be subject to an annual economic escalation effective on the first day of January
of each contract year beginning in CY 2005. All such rates shall be adjusted at an annual escalation rate/price adjustment as defined by the following formulae. 

Price Adjustments shall be determined 90 days prior to the start of each calendar year. 

For Power-by-the Hour and all Flat Rates, the Price
Adjustment percentage (PA) will be determined according to the following formula: 
  

							
	PA	  	=             (P) × (L + M – 1)
		
	where P	  	=             applicable Support Service Price
				
	L 	  	= Labor	  	=                        	  	0.55 × Forecasted AHE372NS1 for the upcoming year
		  		  		  	                                    
20.6790
				
	M 	  	= Material	  	=	  	    0.45 × Forecasted PPI372NS for the upcoming year
		  		  		  	                                    1.4834
	
	For T&M Labor Rates, the Price Adjustment (PA) will be determined using only the labor index according to the following formula:
			
	PA	  	=             (P) × (L – 1)	  	
		
	where P	  	=             applicable Fixed Price Labor Rate
			
	L 	  	= Labor            =	  	        Forecasted AHE372NS2 for the upcoming year
		  		  		  	                                    
20.6790

 where, AHE372NS is the Average Hourly Earnings index established in Standard and Poor’s Data
Resources Incorporated; PPI372NS is the Producer Price Index established in Standard and Poor’s Data Resources Incorporated; and the denominators of the equations above are the applicable index values published for 2nd quarter of the given calendar year. 
 If, prior to calculation, the U.S. Department of
Labor changes the base year for determination of the AHE or PPI values, such re-based values will be incorporated in the Price Adjustment calculation. 

If, prior to calculation, the U.S. Department of Labor or Standard and Poors substantially revises the methodology used for the determination
of the values to be used to determine the index values, or for any reason has not released values needed to determine the applicable Price Adjustment, the parties will, prior to calculation, select a substitute for such values from data published by
Standard and Poors DRI or other similar data reported by non-governmental United States organizations. The substitute will lead in application to the same adjustment result, insofar as possible, as would have
been achieved by continuing the use of the original values as they may have fluctuated during the applicable time period. 
  

 

	1 	 For purposes of the calculation, use the index forecast published in the second calendar quarter of the year of
the adjustment. Thus, for an adjustment applicable to calendar year 2006, calculated 90 days prior to January 1, 2006, use the index published in 2nd quarter 2005. 

	2 	 For purposes of the calculation, use the index forecast published in the second calendar quarter of the year of
the adjustment. Thus, for an adjustment applicable to calendar year 2006, calculated 90 days prior to January 1, 2006, use the index published in 2nd quarter 2005.

 MN Airlines Inventory Support Agreement 8 Oct 2003 

 

 In the event escalation provisions are made
non-enforceable or otherwise rendered null and void by any agency of the United States Government, the parties agree, to the extent they may lawfully do so, to negotiate an adjustment to the prices to reflect
an allowance for increases or decreases in labor compensation and material costs. 
 Note:     Prior to applying index
values to dollars or rates, all index calculations shall be carried to the nearest ten-thousand (x.xxxx) prior to the next calculation. Any rounding of a number, as required under this clause with respect to
escalation, will be accomplished as follows: if the first digit of the portion to be dropped from the number to be rounded is five or greater, the preceding digit will be raised to the next higher number. Rounding will be performed at each level of
calculation prior to proceeding to the next level.

 SCOPE OF SERVICES 

Inventory Maintenance; Basis for Provisioning 

Delta will purchase and maintain a mutually agreed upon inventory of Components, sufficient to support the operation of the fleet of Aircraft
within the program performance measures. Delta shall provide system wide Component support to the Sun Country fleet which shall include maintaining a supply and inventory management and tracking function for Components, and providing Components to
Sun Country on an exchange basis, as described below. The Components shall be integrated into Delta’s inventory for use on both Delta aircraft and Sun Country’s Aircraft. Delta will allocate certain inventory to Sun Country at stations
where Delta does not operate aircraft of the same type as the Aircraft (the “Allocated Inventory”) in quantities that are mutually agreed upon between the parties. Delta may utilize any of the Allocated Inventory for its own needs,
however, in such event, Delta shall use commercially reasonable efforts to replace such Allocated Inventory as soon as is practical. 
 Delta will supply
serviceable Components to Sun Country on an exchange basis; that is, title to Components shipped to Sun Country shall vest in Sun Country and title to removed Components will vest in Delta, each upon the installation of the replacement Component on
an Aircraft. 
 Configuration Management 

Delta shall have configuration management responsibility for all Common Components. Sun Country shall have configuration management
responsibility for all Non-Common Components. Sun Country shall cooperate with Delta to ensure that Common Components configuration is maintained in accordance with FAA accepted practices. 

Reliability Monitoring & Tracking 

Delta shall provide to Sun Country, an unscheduled removal report for Common Components removed from Delta’s 737-NG aircraft. This report shall be provided quarterly to aid in monitoring Common Component reliability trends, and failures, in order to determine any adjustment to the Common Component inventory. Sun Country
shall provide to Delta, an unscheduled removal report for Components removed from Sun Country Aircraft. This report shall be provided quarterly to aid in monitoring Component reliability trends, and failures, in order to determine any adjustment to
the Component inventory. 
 Delta will utilize its existing reliability tracking program to track Common Components. The systems to be
tracked, the calculations to be made and the performance standards against which the systems are measured will be in accordance with FAA accepted practices. Data required to support such a tracking program will be supplied to Delta by Sun Country as
requested by Delta. Sun Country will co-operate with Delta to further develop acceptable data models and methods of data transmission. For Common Components operating on Delta aircraft, Delta will periodically
review the trend analysis and implement corrective action if reliability falls below Delta’s established statistical limits. Delta will not track the reliability of Components operating on Sun Country Aircraft. 

  
 16 

 Performance Measures 

Delta shall provide Component support to Sun Country to ensure that Sun Country Aircraft do not experience a twelve (12) month rolling
average Parts Related Delay rate greater than the Parts Related Delay rate goal that Delta sets for its own 737-NG fleet.. Such goals shall be provided to Sun Country as they are established and revised from
time to time. Should Component support fail to meet this performance measure, Delta shall assist Sun Country in evaluating the cause of such failure and determine and implement the appropriate corrective action(s) in a timely manner so as to meet
the performance measure. 
 Adjustments to Allocated Inventory 

Delta and Sun Country, as mutually agreed, will adjust the type and quantity of Allocated Inventory from time to time as necessary to meet
program performance measures. 
 Inventory Management 

Delta shall utilize its existing inventory management system to manage, order, and track the Allocated Inventory. 

Maintenance and Repair 
 Delta
shall be responsible for an off-wing repair and overhaul for all Components. Delta will maintain the Common Components in accordance with current manufacturer’s Standard Practice manuals and Component
Maintenance Manuals, which contain Delta repairs, processes, and material equivalents noted on the Delta information pages. All Delta data have been classified and substantiated as FAA acceptable (minor) and/or FAA approved (major) in accordance
with Delta’s Continuous Airworthiness Maintenance Program. Delta will ensure all Non-Common Components will be maintained in accordance with the applicable manufacturer’s Component Maintenance
Manuals in accordance with FAA Title 14 of the Code of Federal Regulations (FAR) Parts 43, 145, and/or 121. 
 Misuse or Abuse of Components

 Repair and replacement of Components damaged due to Sun Country’s use of such Component outside of the manufacturer’s
recommendations, improper operation/maintenance, foreign object damage, abuse, negligence or accidental damage shall be repaired by Delta at Delta T&M rates, or if replacement is necessary, shall be replaced at the then current manufacturers
list price. Delta shall bear all costs for the replacement of all Components deemed beyond economic repair (BER) due to normal wear and tear. 
 No
Fault Found (NFF) Components 
 For all Components returned to Delta for Service under the PBTH rate, if Delta cannot confirm a
failure of such Component after inspection or testing, or such inspection or testing shows the Component to be in serviceable condition (“NFF”), then Delta will notify and provide inspection and testing results to Sun Country. For NFF
Components, Sun Country will pay to Delta, $500 for testing and recertification of NFF Component(s). If testing and recertification is accomplished by a Delta vendor, Sun Country will pay Delta’s substantiated cost plus eight percent (8%). The
preceding notwithstanding, Sun Country will not be charged a NFF fee if the removal of the Component was based on a troubleshooting recommendation by Delta that such Component be removed. For Delta tested and
re-certified NFF Component(s), if such Component(s) is subsequently removed within one hundred (100) Flight Hours of installation with a confirmed failure for the same reason as identified on the prior
removal, then Delta will repair such Component and, in addition, will either: (i) issue Sun Country a credit against an unpaid Delta invoice issued for a NFF charge, or (ii) credit to Sun Country the amount paid by Sun Country for the NFF
charge. 

  
 17 

 Airworthiness Directives (ADs). 

Delta will, as part of the Services, review, analyze and issue engineering documentation for the incorporation of ADs into Common Components. Sun Country will
review, analyze and issue engineering documentation in a format acceptable to Delta the instructions for the incorporation of ADs into Non-Common Components. The actual accomplishment of any ADs on Components
will be charged to Sun Country at Delta Time & Material Rates, but only for the amount of such Components delivered with Sun Country’s Aircraft that did not have the particular AD complied with. The amount of labor charged for
accomplishing any AD will be those number of man-hours specified in the AD, or if the AD fails to specify the number of man-hours, then such information will be obtained
from the relevant equipment manufacturer. If the manufacturer specifies the number of man-hours, then not more than such number will be invoiced by Delta. If the manufacturer does not supply such information,
Delta will estimate the labor required to accomplish the AD and notify Sun Country. Delta will track and invoice Sun Country for the actual labor necessary to accomplish the AD, advising of any substantive changes, if they occur, that would
significantly alter the estimate. Any labor expended on Services not required to accomplish the AD will be allocated as appropriate either to the PBTH Rate or to the Delta Time & Material Rate as provided elsewhere herein. The material part
of the Delta Time & Material Rate charge will be for only that material necessary to complete the AD per the information in the AD. If the AD fails to provide the list of materials necessary to accomplish the AD, such information will be
obtained from the relevant equipment manufacturer. If that information is not available, Delta will estimate the material required to accomplish the AD. Delta will track and invoice for the actual material necessary to accomplish the AD. If the only
reason for removing a Component from an Aircraft was to accomplish an AD, Delta will invoice for, and Sun Country will pay to Delta, all the costs required for the Services associated with the accomplishment of the AD and other Services required by
the Maintenance Program to return the Component to serviceable condition at Delta Time & Material Rates. Any other work performed during such a shop visit to enhance any performance or life of the Common Component will be borne by Delta. To
the extent allowed by the time limits of the AD, Delta will make all reasonable efforts to accomplish ADs in conjunction with other scheduled maintenance on such Component. 

Service Bulletins (SBs) 
 As deemed
necessary by Delta, Delta will, as part of the Services, review, analyze and issue engineering documentation for the incorporation of SBs into Common Components. For Common Components requiring incorporation of an SB to meet Delta modification
standard, Delta will incorporate that SB at the time Delta performs other Services on such Components, in accordance with the following: 
 SBs Costing
No More Than $1,200 
 If Delta reasonably estimates the incorporation of an SB into a Common Component will cost no more than $1,200,
when calculated at Delta Time & Material Rates, then such SB will be incorporated into the Component as part of the Services provided under the PBTH Rate. Such SB may be automatically incorporated without Sun Country permission so long as
Sun Country is provided with notice and the SB does not change the fit, form or function of the Component. In the event the SB will change the fit, form or function of the Component, then Delta shall provide Sun Country with a written copy of Delta
Engineering Order (EO) for such change. 

  
 18 

 SBs Costing More than $1,200 

If Delta reasonably estimates the incorporation of an SB into a Common Component will cost more than $1,200, when calculated at Delta
Time & Material Rates, then such SB will be incorporated at Sun Country’s expense at Delta Time & Material Rates, but only for the amount of such Components delivered with Sun Country’s Aircraft that do not have the
particular SB incorporated. In the event that the Component manufacturer or some other person compensates Delta for the incorporation of the SB, then Sun Country shall not be charged to the extent such compensation reduces Delta’s cost for
incorporating the SB below $1,200. 
 Determining the Cost of SBs 

The determination of the time and material elements of Delta Time & Material Rates for incorporation of SBs provided for above will be calculated in
accordance with this Section. The markup on materials will be based on the current list price. The labor part of the Delta Time & Material Rate charge will be only for that number of man-hours
specified in the SB, or if the SB fails to specify the number of man-hours, then such information will be obtained from the relevant equipment manufacturer. If the manufacturer specifies the number of man-hours, then not more than such number will be invoiced by Delta. If the manufacturer does not supply such information, Delta will estimate the labor required to accomplish the SB and notify. Delta will track and
invoice for the actual labor necessary to accomplish the SB, advising of any substantive changes if they occur that would significantly alter the estimate. The material part of the Delta Time & Material Rate charges will be for only that
material necessary to complete the SB per the information in the respective SB. If the SB fails to provide the list of material necessary for accomplishment of the SB, such information will be obtained from the appropriate equipment manufacturer.
Using the bill of material specified either in the SB or by the manufacturer, Delta will flat-rate the material for the SB at the then-current prices. If that information is not available, Delta will estimate the material required to accomplish the
SB. Delta will track and invoice for the actual material necessary to accomplish the SB. Labor expended on Services not required by the accomplishment will be allocated as appropriate either to the PBTH Rate or the Delta Time & Material
Rate as provided elsewhere herein. If the only reason for removing a Component from an Aircraft is to accomplish the performance of an SB. Delta will invoice for, and Sun Country will pay to Delta, all the costs required for the Services associated
with the accomplishment of the SB and other Services required to return the Component to serviceable condition at Delta Time & Material Rates. 

Modification Compatibility 
 If Sun
Country chooses not to accept a Component modification that Delta is performing on Components for Delta’s fleet and such decision creates the need for a larger inventory of Non-Common Components, Sun
Country will either; (i) purchase, or authorize Delta to purchase, such additional Non Common Components for the inventory in a quantity sufficient to support the requirements of the Sun Country fleet, as is mutually agreed between Delta and
Sun Country, or (ii) agree to an amend this Agreement to remove each such NonCommon Component from Delta’s support obligations. 
 Sun Country
will create or revise all Sun Country documentation and equipment, including task cards, Illustrated Parts Catalogs, test equipment and Aircraft, that are affected or necessitated by all such EOs, ADs, and SBs related to Components. 

  
 19 

 Undocumented Components or Repairs 

If, in performing any Services, Delta finds any undocumented Component or repair, then Delta will promptly notify Sun Country along with
providing documentation of the undocumented Component and/or repair. Sun Country shall then substantiate such Component within three (3) days of Delta’s notice. If Sun Country is unable to substantiate such Component, Delta will not accept
the undocumented Component for Services or remedy the undocumented repair at Delta Time & Material Rates. 
 Supply Response Times

 When a Component requires removal from an Aircraft and Sun Country does not have a replacement Component available, Sun Country
will notify Delta Front Desk and, within thirty minutes of receiving any such notice, Delta will: (i) acknowledge receipt of the request; (ii) advise Sun Country whether a replacement Component is in stock or must be obtained from another
source; and (iii) either give Sun Country complete shipping information for the replacement Component or advise Sun Country of when such information will become available. Delta or its suppliers will ship a Component to the location designated
by Sun Country as soon as possible; but in any event, to comply with program performance measures, all Components will be shipped within twenty-four (24) hours of Delta’s receipt of a request at least ninety percent (90%) of the time in
the case of Airframe and Engine Components and ninety-five percent (95%) of the time in the case of APU Components. Such percentages will be calculated on twelve-month rolling averages. If either such rolling average falls below the program
performance measures, Delta and Sun Country will identify the reasons for the program performance shortfall. Upon such identification, Delta and Sun Country will take prompt action to ensure that the Components are either stocked or sourced in
sufficient quantities to meet the program performance measures stated in this Annex. Notwithstanding the preceding sentences, Delta will ship Components using the same degree of expediency for a Sun Country AOG situation that Delta generally uses
for a Delta AOG situation. If Delta’s general AOG handling methods are not sufficient in a particular situation, then at Sun Country’s request, Delta will arrange for unique shipping methods, such as the hiring of private aircraft to ship
the Component, all at Sun Country’s cost and expense. 
 If a Common Component can not be provided to Sun Country and Sun Country has
an Aircraft that is AOG for such Component, Delta will provide assistance to Sun Country in locating such Component for Sun Country to lease or borrow. In such cases, Delta will be responsible for the loan or lease charge until such Component is
provided to Sun Country by Delta. 
 Return of Components 

Sun Country will return each Component removed from an Aircraft to Delta’s facility within five (5) days of its removal from the
Aircraft. Sun Country will arrange for all such shipments except in those instances when Delta or a Delta subcontractor actually removes and replaces an Component. In such instances within the United States, Delta will pack, ship and track shipment
of such Component. In such instances outside the United States, Delta will coordinate with Sun Country’s maintenance control center on the return of the Component. 

  
 20 

 Shipment Methods and Costs; Packing; Required Records 

Method of Shipment and Costs. 
 At Sun
Country’s option, for any Component which requires Services, Sun Country will provide for shipment at its own cost and expense via any reasonable method that will meet the Component return time requirement. 

Proper Packaging. 
 Delta will initially
deliver all serviceable Components in reusable Category 1 containers (as defined in ATA Specification 300). Sun Country will return each removed Component in the same or equivalent container as the one in which the replacement was shipped. If that
container or its equivalent is not returned to Delta, Sun Country will be charged for its replacement. Each Component shipped by Delta will have attached to it a tag indicating serviceability under the standards of FAR Part 121. Regardless of the
method of shipment, Sun Country shall be responsible for ensuring that Components are properly prepared, packaged, labeled and documented under applicable ATA 300 and hazardous goods regulations. In the event Delta receives a Component from Sun
Country that is not properly packaged under applicable ATA 300 and hazardous goods regulations, Delta will so notify Sun Country in order for Sun Country to provide a proper package for use by Delta in returning the Component to Sun Country. In the
event Sun Country fails to provide the proper packaging, Delta may provide such packaging required under the applicable ATA 300 and hazardous good regulations and Sun Country shall compensate Delta for such packaging at Delta Time &
Material Rates. 
 Records and Reports. 

Sun Country will furnish the following data with each Component offered for Services: the Aircraft’s registration and serial number; the
Component name, model, and serial number; the number of .Flight Hours and cycles the Component accumulated on the Aircraft; the dates the Component was installed and removed and the reason for removal. Concurrent with shipment of serviceable
Components Delta will provide data on each such Component, including, as available, aggregate flight hours and cycles accumulated. serial number; the Component name, model and serial number; the total number of hours and cycles on the Component.

 At end of Term or in case of early termination, Sun Country shall provide Delta with a written list, by serial number, part number, and
nomenclature, of Components eligible for Service that arc installed on Sun Country Aircraft. Upon receipt of such written list, Delta shall provide Sun Country with all available records for such Components. 

Warranty Administration 
 On behalf
of Sun Country, Delta will administer claims against manufacturers of removed Components on which a warranty is in effect. Delta will retain any warranty related compensation. To achieve this purpose, Sun Country will cause the assignment to Delta
of all warranty rights related to the Components. If Sun Country has not made reasonable efforts for such assignment before a warranted Component must be repaired, Sun Country will be charged for such repair at T&M. All assignments of warranty
rights to Delta pursuant to this Section will expire immediately upon termination or expiration of this Agreement and such rights will revert to Sun Country. 

Project Manager; Customer Representatives 

Delta will assign an employee with experience in project management to coordinate all aspects of the Services and to be the primary liaison
with Sun Country during the term of the Agreement. Sun Country will 

  
 21 

 
designate one or more representatives who at all times during the term of this Agreement will have the authority to accept or reject work performed by Delta. Sun Country will furnish to
Delta’s Project Manager a list of its personnel, with contact information, who are responsible for the subjects covered by this Agreement. Delta will furnish to Sun Country a list of its personnel, with contact information, who are responsible
for the subjects covered by this Agreement.

 ANNEX A2 

Charges & Payments 

Allocated Inventory - Flat Rate 
 Sun
Country shall pay to Delta a monthly rate of 1.5% times the value of the Allocated Inventory provided to Sun Country at the mutually agreed to locations. The total value of Allocated Inventory will be calculated on the last day of the month. The
value of the Allocated Inventory on the last day of the month will be the basis for the payment due and such payment will be made in accordance with Section 3.2 of the Inventory Support Agreement. The Allocated Inventory value is determined by
the average list price of the Component in Delta’s inventory system times the total number of Components allocated. The type and quantity of Components allocated to Sun Country shall be determined to meet the program performance measures

Pool Inventory - Flat Rate 
 Sun Country
shall be charged a flat monthly fee for the use of Common Components at stations where Components already exist to support Delta B737NG operations. Sun Country shall pay to Delta a monthly rate of 1% times the current value of Common Station
inventory per aircraft, as most recently reported by Delta to Sun Country and revised from time to time, times a ratio of the number of Common Stations to the total number of SCA 737NG stations, times the number of Aircraft in service for that
month. Such payment will be made in accordance with Section 3.2 of the Inventory Support Agreement. The rate for Pool Inventory will be calculated on the last day of each month. For Aircraft introduced into or removed from Sun Country’s
fleet during any particular month, the contribution to payment for pool inventory for that particular Aircraft for that particular month shall be pro-rated based on the percentage of that month such Aircraft
has spent in revenue service.

 Attn: Royall G.G. 

 

	 	Re:	 License for use of Delta STC SA2166SO on MSN 25493 

Dear Sirs: 
 This letter agreement sets forth
the terms and conditions pursuant to which Delta Air Lines, Inc. (“Delta”) will grant to Raytheon Systems Company (“Licensee”) a non-exclusive,
non-transferable license to use a certain Delta Supplemental Type Certificate (“STC”) in the installation of a hatch kit, part number
53-0496-500, in the aircraft owned or operated by Licensee bearing manufacturer’s serial number 25493 (the “Aircraft”). 

 

	1.	 Scope of License. 

Delta hereby grants to Licensee a non-exclusive,
non-transferable license to use Supplemental Type Certificate number SA2166SO for the installation by Licensee or its authorized repair or modification facility of a hatch kit, part number 53-0496-500, in the Aircraft. Delta represents to Licensee that Delta owns the rights to such STC and has the right and authority to grant this license. This license may not
be transferred, sold or assigned by Licensee, nor may Licensee use it for the purpose of modifying any other parts or any other aircraft for itself or any other operator; provided, however, that Licensee may assign its interest herein
with a transfer of ownership or possession of the Aircraft modified pursuant to the terms of this license, and any transferee under the terms of this provision may transfer its interest herein in the same manner. 

 

	2.	 Price for License. 

Pursuant to a Purchase Agreement dated as of even date herewith, Licensee will purchase from Delta one (1) hatch kit, part number 53-0496-500, in the amount of Ten Thousand Three Hundred Forty Seven Dollars ($10,347), which purchase price shall include the STC licensed hereunder. Licensee agrees and
acknowledges that the STC shall be used solely in connection with the Aircraft. 
  

	3.	 Taxes. 

In addition to the amounts set forth above, Licensee will reimburse Delta (net of any additional taxes of such reimbursement) the amount of any
and all taxes (except United States Income taxes) and fees of whatever nature, including customs duties and fees, paid or incurred by Delta as a result of or in connection with granting the license hereunder. If claim is made against Delta for any
such tax, Delta will promptly notify Licensee. If seasonably requested by Licensee in 

 
writing, Delta will at Licensee’s expense take such action as Licensee may reasonably direct with respect to such claim, and any payment by Delta of such tax will be made under protest, if
protest is necessary and proper. If payment is made, Delta will, at Licensee’s expense, take such action as Licensee may reasonably direct to recover such payment and will, if requested, permit Licensee in Delta’s name to file a claim or
prosecute an action to recover such payment. 
  

	4.	 Waiver; Limitation of Liabilities. 

THE OBLIGATIONS AND LIABILITIES OF DELTA HEREUNDER, AND THE RIGHTS AND REMEDIES OF LICENSEE HEREUNDER ARE EXCLUSIVE AND IN SUBSTITUTION FOR,
AND LICENSEE HEREBY WAIVES, RELEASES AND RENOUNCES ALL OTHER WARRANTIES, GUARANTEES, OBLIGATIONS, LIABILITIES, RIGHTS AND REMEDIES, EXPRESS OR IMPLIED, ARISING BY LAW OR OTHERWISE, WITH RESPECT TO ANY ERROR IN DATA, THE PERFORMANCE OF SERVICES, OR
ANY OTHER THING DELIVERED UNDER THIS AGREEMENT, THE VALIDITY OR SCOPE OF ANY PATENT INCLUDED IN THE DATA, ANY ACTUAL OR ALLEGED INFRINGEMENT OF ANY THIRD PARTY-OWNED PATENT BY ANY PREPARATION, TRANSFER OR USE OF DATA AND WITH RESPECT TO ANY
NONCONFORMANCE OR DEFECT IN PROCESSES USED OR PRODUCTS MADE IN ACCORDANCE WITH OR COVERED BY THE DATA, INCLUDING BUT NOT LIMITED TO (A) ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS, (B) ANY IMPLIED WARRANTY ARISING FROM COURSE OF
PERFORMANCE, COURSE OF DEALING OR USAGE OF TRADE, (C) ANY OBLIGATION, LIABILITY, RIGHT, CLAIM OR REMEDY IN TORT, WHETHER OR NOT ARISING FROM DELTA’S NEGLIGENCE, WHETHER ACTIVE, PASSIVE OR IMPUTED, AND (D) ANY OBLIGATION, LIABILITY,
RIGHT, CLAIM OR REMEDY FOR LOSS OF OR DAMAGE TO ANY PROPERTY INCLUDING, BUT NOT LIMITED TO, ANY AIRCRAFT, AND (E) ANY OBLIGATION, LIABILITY, RIGHT, CLAIM OR REMEDY FOR LOSS OF USE, REVENUE OR PROFIT, OR FOR ANY OTHER DIRECT, INCIDENTAL OR
CONSEQUENTIAL DAMAGES. 
  

	5.	 Indemnification. 

Licensee agrees to defend, indemnify and hold Delta, its assignees and their respective officers, agents and employees harmless from and
against all liabilities, damages, losses, expenses, claims and judgments, including all costs and expenses incident thereto, which may be suffered by, accrued against, be charged to or recoverable from Delta, its assignees and their respective
officers, agents or employees, by reason of loss of or damage to property, including any aircraft, or injury to or death of any person, whether or not occasioned by Delta’s negligence, active, passive or imputed arising out of or in any way
connected with the use by Licensee or any assignee or transferee of any rights granted hereunder, services provided in connection therewith, or the repair, modification, maintenance or use of any aircraft, component or part. 

  
 - 2 - 

	6.	 Proprietary Information; Remedies. 

Licensee acknowledges and agrees that the rights to ownership of the STC and the data reflected therein are solely with Delta and are
proprietary to it and will be used by Licensee or its authorized repair or modification facilities solely for the purposes described herein. Licensee agrees never to assert an ownership interest in the STC or the data reflected therein, or take any
action contrary to Delta’s rights therein. In the event Licensee asserts such interest or takes such action, Licensee agrees that Delta may revoke this license with respect to the Aircraft modified hereunder. Should Delta notify Licensee of
such revocation, Licensee will immediately cease all aircraft operations under the STC. The parties agree that, because of the nature of the rights Delta has under this license, remedies at law may not be adequate to provide for effective
enforcement of Delta’s rights hereunder and, accordingly, Licensee agrees and acknowledges that Delta may seek and obtain injunctive relief to enforce its rights hereunder, and Licensee further agrees not to contest the jurisdiction of any U.S.
District Court in which Delta may bring such an action. 
  

	7.	 Governing Law; Negotiated Agreement; Entire Agreement. 

This Agreement, including all matters of construction, validity and performance, shall be governed by, and construed in accordance with, the
laws of the State of Georgia, U.S.A. as applicable to contracts entered into in such state by residents thereof and to be performed wholly within such state, and without reference to conflicts of law principles. Licensee and Delta agree that this
Agreement, including Articles 4, 5 and 6, has been the subject of discussion and negotiation and is fully understood by the parties, and that the royalty for the use of the license and the other terms hereof were arrived at in consideration of
Articles 4, 5 and 6. This Agreement contains the entire agreement between the parties with respect to the subject matter hereof and supersedes any previous proposals, understandings, commitments or representations whatsoever, oral or written. This
Agreement shall not be varied except by written agreement of the same or subsequent date signed on behalf of Licensee and Delta by their respective duly authorized representatives.

 If this accurately sets forth our understanding, please sign both counterparts of this letter and return one
to the attention of the undersigned on or before February 4, 2002.
