	10.	 The following language is hereby added as a new section at the end of Annex A, immediately preceding Annex A1:

 Assessment of Common Components 

As requested from time to time by MN Airlines, Delta will analyze the component listing of any Aircraft that MN Airlines is
interested in leasing and provide MN Airlines with a report identifying the components within such Aircraft that would constitute Common Components under this Agreement. Delta shall use commercially reasonable efforts to provide any such report
within seven (7) business days of receiving the necessary information from MN Airlines that is required to provide the report. 

 Engineering Support Services 

To the extent necessary to support the scope of services as set forth in this Annex A, Delta will provide the following
engineering support services: 
  

	 	•	 	 General Shop Support – Includes developing 1-off repairs as well as multi-use repairs for a particular Component. 

  

	 	•	 	 Outside Vendor Shop Support – Delta will provide engineering oversight on Components that are sent out to
outside vendors. 

  

	 	•	 	 Component Configuration – Review and approve implementation of Service Bulletins (SB) as needed.

  

	 	•	 	 Reliability – From internally developed & managed reliability (RI) and Component (CPI) indexes,
Delta will monitor and investigate reliability drivers on components. 

 Delta acknowledges that MN Airlines may at some
point in the future have a capability of performing all engineering support services in-house. In such event, to the extent these engineering support services are redundant with those being provided by MN
Airlines in-house, the parties shall discuss in good faith the reduction or removal of the engineering support services from this Annex A and a commensurate, pro-rata
reduction or removal of the associated fee set forth in Section 2 of Annex A2. 
 Supply Response Time 

The Supply Response Time commitment from Delta for Common Components shall be as follows: 

 

							
	 Situation and Component
Category 
	  	 Supply Response Time
	  	Achievement
of Supply
Response
Time (based
on rolling
3-month
average)	 
	 AOG Aircraft due to ESS 1 Component
	  	No more than 3 hours between receipt of request and Dispatch *	  	 	96	% 
	 AOG Aircraft due to Component that is in stock at Delta’s MSP facility
	  	No more than 3 hours between receipt of request and available for MN Airlines pick-up	  	 	96	% 
	 All other situations
	  	No more than 12 hours between receipt of request and Dispatch *	  	 	90	% 

  

	*	 Dispatch = MN Airlines is notified of Delta flight number and AWB that the requested Component is booked on or
that requested Component is available for pickup at a Delta facility if part is being shipped by MN Airlines. 

 For
purposes of this Section, “ESS” means the Essentiality Code for a particular Component, as set forth in the applicable Boeing Aircraft manual. 

Delta shall provide MN Airlines with a report of Delta’s achievement of the Supply Response Time for each category at each quarterly
business review meeting. In addition, the then-current rate of Delta’s achievement of the Supply Response Time for each category shall be available for MN Airlines review within the Integrated Exchange Website (IEW). 

 In the event Delta fails to meet the applicable Supply Response Time for any category for
any reason other than Excusable Delay (as set forth in Section 6 of the Agreement) or a delay caused by MN Airlines, and MN Airlines has an Aircraft that will be prohibited from flying a scheduled service solely due to Delta not meeting Supply
Response Time fat a specific Component within such category (the “AOG-Causing Part”), MN Airlines shall provide Delta with notice of such situation (the “AOG Notice”) and provide Delta with
an opportunity to meet MN Airlines’ reasonable requirements for delivery of the AOG-Causing Part. If Delta fails to meet such requirements, then Delta will provide MN Airlines with a credit against future
invoices in an amount equal to the actual commercially reasonable cost paid by MN Airlines to a third party for the rent of a replacement Component for the period of time between the delivery of the AOG Notice and MN Airlines’ subsequent
receipt of the AOG-Causing Part from Delta. The foregoing remedy shall be Delta’s sole obligation and MN Airlines’ sole remedy for failure to meet any Supply Response Time. 

Miscellaneous Services 

As requested by MN Airlines, Delta will use commercially reasonable efforts to provide additional value-added services (such as
common procurement initiatives; access to available Component lease units; tooling support; and prognostic, predictive maintenance and senor initiatives) to MN Airlines to the extent that such services are directly related to the services set forth
in this Annex A and can be performed by Delta without incurring incremental third party costs. Certain additional value-added services may be subject to additional applicable terms and conditions.

 In the event MN Airlines adds an additional aircraft to the fleet of Aircraft, that is reasonably determined by Delta to cause
a material increase to Delta’s cost to provide the Services (as measured on a per Aircraft basis), Delta reserves the right to adjust the PBTH Rate for that particular additional aircraft upon thirty (30) days’ advance written notice.
During such thirty (30) day notice period, upon request from MN Airlines, the parties shall negotiate in good faith to determine an alternative way of compensating Delta for the increase in cost caused by the particular additional Aircraft (such as
a one-time payment from MN Airlines), provided that if mutual agreement on such alternative is not reached by the parties, the increased rate shall go into effect as of the end of such thirty (30) day period
for that particular aircraft. 

 Attachment 2 to Amendment 

ANNEX A2 
 Charges and Payment
Terms 
  

	 	1.	 Component Access and Exchange Flat Rates 

Delta shall charge MN Airlines and MN Airlines shall pay to Delta a flat monthly fee for Component access and exchange. Such fee shall be computed monthly by
multiplying the number of Aircraft covered under this Agreement times the applicable flat fee set forth in the table below: 
  

																	
	 	  	Total number of
Aircraft covered by this
Agreement:
0-30	 	  	Total number of
Aircraft covered by
this Agreement:
31-40	 	  	Total number of
Aircraft covered by this
Agreement:
41-50	 	  	Total number of
Aircraft covered by
this Agreement:
51 or more	 
	 Component Access and Exchange – Flat Rate (per Aircraft/per month)
	  	$	3,500	 	  	$	3,235	 	  	$	2,752	 	  	$	2,296	 

 Such payment shall be made in accordance with Section 3.2. The rate for Component access and exchange shall 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. 

 

	 	2.	 Engineering Support Services Flat Rate 

Subject to Section 10 of this Amendment, Delta shall charge MN Airlines and MN Airlines shall pay to Delta a flat monthly fee of $25,000 for the
engineering support services described in Annex A. Such payment shall be made in accordance with Section 3.2. 
  

	 	3.	 PBTH Rates 

Delta shall charge MN Airlines and MN Airlines shall pay to Delta a fee each month based on the applicable power-by-the-hour rate set forth below (the “PBTH Rate”), as compensation for Services which are described herein as being provided on a power-by-the-hour basis. Each calendar month during the Term, Delta shall invoice to MN Airlines an amount equal to the product of
applicable PBTH Rate times the total number of Flight Hours for all Aircraft during such month. MN Airlines shall 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 shall allow Delta representatives to inspect its operating records with respect to the Aircraft to verify the accuracy of the Flight Hour information. 

Valid prior to October 9, 2018: 
  

													
	 Aircraft age at time of invoice
	  	0 to 36 months	 	  	37 to 60 months	 	  	6l or more months	 
	 PBTH Rate
	  	$	66.51	 	  	$	112.66	 	  	$	148.40	 

 Valid on and after October 9, 2018: 

 

																	
	 Aircraft age at time of invoice
	  	0 to 24 months	 	  	25 to 36 months	 	  	37 to 48 months	 	  	49 or more months	 
	 PBTH Rate
	  	$	15.93	 	  	$	25.99	 	  	$	70.42	 	  	$	83.83	 

 Aircraft age, for purposes of determining the applicable PBTH Rate, is based on the number of months elapsed since the
delivery of the Aircraft in new condition by the original equipment manufacturer to the initial owner or operator. 
 Should Delta and MN Airlines enter
into an agreement for the provisioning of engine maintenance services on MN Airlines’ 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 Airlines with a more favorable rate. · 
  

	 	4.	 Minimum Annual Flight Cycles 

The parties agree that the commercial terms of this Agreement are premised on the operation of each Aircraft for at least 3,000 Flight Hours per year, measured
on an annual basis (the “Minimum Annual Flight Hours”), provided, however, that the measurement period for 2018 shall be from October 9 to December 31 and the Minimum Annual Flight Hours for 2018 shall be prorated accordingly,
resulting in 689 Flight Hours per aircraft. As a result, MN Airlines agrees to compensate Delta for any difference between actual utilization of the Aircraft and the Minimum Annual Flight Hours in accordance with this Section. On January 1 of
each calendar year during the Term beginning January 1, 2019, and on the date of expiration or termination of the Agreement, Delta shall invoice MN Airlines for an Annual Additional Payment for the immediately preceding calendar year for each
Aircraft, calculated on a per Aircraft basis as follows (and prorated for any partial years): 
 Annual Additional Payment per Aircraft =
applicable PBTH Rate for the measurement period* (3,000 – actual Flight Hours for such Aircraft during the measurement period) 
 If the
actual Flight Hours for any Aircraft during the measurement period is equal to or greater than 3,000, then the Annual Additional Payment for such Aircraft is 0. 

For purposes of determining the Annual Additional Payment, Flight Hours may not be carried over from a previous year or carried over from Aircraft to
Aircraft. For clarity, MN Airlines shall not receive a credit or refund for any Aircraft that exceeds 3,000 Flight Hours per calendar year. The Minimum Annual Flight Hours for any Aircraft that was added to the MN Airlines fleet during the Term
shall be prorated for partial calendar years based on the date that such Aircraft began commercial service as part of the MN Airlines fleet. 
  

	 	5.	 Time & Material Rates 

All services performed by Delta outside of the scope of the PBTH Rate shall be charged to MN Airlines on a time and materials basis in accordance with the
rates set forth below (the “Delta T&M Rates”): 
  

	 	a.	 $122.42 per hour for mechanics and inspectors. 

 

	 	b.	 $189.78 per hour for engineers and analysts. 

	 	c.	 New material at Delta’s cost plus twelve (12%) percent with a per item cap on the markup of $1,711.21 and
a per line item cap on the markup of $3,422.41 

  

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

  

	 	e.	 MN Airlines-supplied parts at 5% of MN Airlines’ cost up to a maximum of $342.24. Parts or kits provided
directly by the original equipment manufacturer at no charge would not be subject to this handling fee. 

  

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

 

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

 

	 	6.	 MN Airlines Delay Charges 

For every day beyond tine 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) 0.5% 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. 
  

	 	7.	 Invoices 

Invoices will be addressed and sent to MN Airlines at the following address: 

MN Airlines, LLC 
 1300
Corporate Center Curve 
 Eagan, MN 55121 

Attn: Accounts Payable 
 MN Airlines shall pay
such invoices in full, without setoff or withholding, in accordance with the terms of the Agreement. 

 Attachment 3 to Amendment 

ANNEX A3 
 Escalation 

The PBTH Rate and the Delta T&M Rates are expressed in January 2018 United States dollars and are subject to escalation on January 1 of each year
during the Term, beginning on January 1, 2019, as set forth in this Annex A3. All escalations are cumulative. 
  

	 	1.	 The PBTH Rate and the Delta T&M Rates will escalate at a fixed rate of 1% on January 1, 2019.

  

	 	2.	 The PBTH Rate and the Delta T&M Rates will escalate at a fixed rate of 1% on January 1, 2020.

  

	 	3.	 Beginning on January 1, 2021, and on January 1 of each year during the Term thereafter, the PBTH Rate
and the Delta T&M Rates will escalate as follows: 

  

	 	a.	 Delta will calculate the Inflation Index using the formula set forth below for the immediately preceding
calendar year. The result will be rounded to the nearest Whole number. 

  

	 	b.	 If the result of the Inflation Index is equal to or less than 5%, then the PBTH Rate and the Delta T&M
Rates will escalate at a fixed rate of 3%. 

  

	 	c.	 If the result of the Inflation Index is greater than 5%, then the PBTH Rate and the delta T&M Rates will
escalate at a rate of 3% plus 1⁄2 the difference between the Inflation Index and 5%. 

Example: 
 Assume the Inflation
Index is 7%. The PBTH Rate and the Delta T&M Rates would escalate by 4%, calculated as follows: 3% + (0.5 * (7% - 5%)). 
  

	 	4.	 The Inflation Index formula is as follows: 

Inflation Index = 0.55*L + 0.45*M 

L = BLS issued index Aerospace Product and Parts Manufacturing NAICS 336400 (49-0000) as issued and
compared to the prior year each January 1. 
 M = BLS issued index for PPI Commodity data for Transportation equipment-Aircraft and aircraft
equipment, not seasonally adjusted. Series ID WPU 142. 
 For the avoidance of doubt Component Access and Exchange Flat Rates as well as Engineering Support
Services Flat Rate are fixed and not subject to any escalations.
