conditions mentioned in such notice for a further term as above provided, or for such farther term as may be stated in such notice. In the event that Tenant shall give notice as stipulated herein of intention to vacate the Property and shall fail or
refuse to so vacate on the date designated by such notice, then it is expressly agreed that Landlord shall have the option either, (a) to disregard the notice so given by Tenant as having no effect, in which case all terms and conditions of

unfit for occupancy or use for Tenant’s purposes. 
 A. To the extent any damage or destruction occurs to the Leased Property the repair
of which is substantially covered by insurance, Landlord may at its sole option, cause Tenant to repair the damages and abate the rent during such period of repair or construction. Upon completion of such repair or construction, all of the terms of
this Lease shall continue in full force and effect. 
 17. Event of Default. 
 It shall be an event of default under this lease if (i) there is an assignment or sublease in violation of the provisions hereof, or (ii) Tenant fails to maintain property and liability insurance as required
under this lease and such failure continues for ten (10) days after receipt of written notice, or (iii) if Tenant shall be in default in the payment of rentals hereunder or if Tenant shall default in any of the covenants herein contained
and such default should continue for ten (10) days for monetary default and thirty (30) days for non-monetary default, after receipt of written notices by Tenant from Landlord for such defaults, or (iv) if Tenant shall be adjudicated
a bankrupt, or shall make an assignment for the benefit of creditors, or shall file a bill in equity or otherwise initiate proceedings for appointment of a receiver of Tenant’s assets, or shall file any proceedings in bankruptcy or for
reorganization or an arrangement under any federal or state law, or if any proceedings in bankruptcy or for the appointment of a receiver shall be instituted by any creditor of Tenant under any state or federal law, or if Tenant is levied upon or
about to be sold out upon 

 
the Property under execution or other legal process. Upon the occurrence of an event of default, then in addition to any other remedy available to Landlord
at law, in equity or otherwise under this lease, the following remedies shall also be available: 
 A. Landlord may cure any default on
behalf of Tenant and shall have a limited right of entry upon the Property where required, solely for this purpose, after ten (10) days from the date of written notice to Tenant advising the latter of the default and of Landlord’s intent
to remedy the same if Tenant fails to do so. Landlord shall also have an immediate right of entry in the event of an emergency, whether or not an event of default has occurred. Tenant shall reimburse Landlord upon demand for all costs incurred in
curing any default, including, without limitation, reasonable attorney’s fees and expenses, together with interest at the legal rate in Pennsylvania (the “Default Rate”) from the date paid until the date reimbursed, which costs and
interest shall be deemed to be additional rent due and payable immediately under this lease. 
 B. Upon notice to Tenant, the term of this
lease shall terminate as of the date set forth in Landlord’s notice (which date shall be at least ten (10) days after the date of the notice) without any right on the part of Tenant to nullify the termination or save the forfeiture by
payment of any sum or by performance of any covenant. 
 C. Landlord may bring one or more actions to recover rent and/or damages, together
with interest at the default rate from the date due to the date paid, and/or to recover possession of the Property, with or without terminating the term of this lease. 
 D. After the Landlord shall recover possession of the Property, Landlord may, at Landlord’s option, with or without terminating this lease, make such alterations and repairs as may be necessary in Landlord’s
sole judgment in order to relet the Property and relet the Property or any part or parts thereof, either in Landlord’s name or otherwise, for a term or terms which may be less than or exceed the period which would otherwise have constituted the
balance of the term of this lease and at such rent or rents and upon such other terms and conditions as in Landlord’s sole discretion, may seem advisable and to such person or persons as may in Landlord’s sole discretion seem best. Upon
each such reletting, all rents received by Landlord shall be applied: first, to the payment of any reasonable costs and expenses of such reletting, including without limit brokerage fees and attorneys fees and all costs of such alterations and
repairs together with interest on such 

 
sums at the default rate from the date paid by Landlord to the date recouped; second, to the payment of rent and other charges due and unpaid hereunder
together with interest on such sums at the default rate from the date due to the date recouped; and the residue, if any, shall be held by Landlord and applied in payment of future rent and other charges as they may become due and payable hereunder.
In the event the rent collected in any month on account of such reletting is less than the amount Tenant is required to pay in that month, Tenant shall pay such difference within ten (10) days after Landlord’s demand. No re-entry or taking
possession of the Property or the making of alterations and/or improvements thereto, or the reletting thereof shall be construed as an election on the part of Landlord to terminate this lease, unless written notice of such intention is given to
Tenant Landlord in no event shall be liable in any way whatsoever for failure to relet the Property or in the event that the Property or any part or parts thereof are relet, for failure to collect the rent under such reletting, provided; however,
that Landlord shall use its best efforts to mitigate its damages resulting from Tenant’s default. 
 E. Notwithstanding any such
reletting without termination, Landlord may at anytime thereafter elect to terminate this lease for a previous breach. Notwithstanding anything in this lease to the contrary, should Landlord at any time terminate this lease for any breach, in
addition to any other remedies it may have, Landlord may recover from Tenant all damages it may incur by reason of such breach, including without limit, the cost of enforcing this lease, and recovering the Property. Landlord may also declare all
rent under this lease immediately due and payable. In such event all rents owing for the remainder of the term shall be due and payable to Landlord immediately. All amounts recoverable from Tenant under this lease shall bear interest from the date
due to the date paid at the default rate. 
 F. Notwithstanding, any other provision of this lease, any amounts due and owing by Tenant at
the expiration or termination hereof shall not be construed as a release by Landlord, and Tenant shall remain liable for the payment of any rents and/or monies due Landlord until fully satisfied. 
 G. No reference to any specific right or remedy shall preclude Landlord from exercising any other fight or from having any other remedy or from
maintaining any action to which it may otherwise be entitled at law or in equity. 

 H. Landlord’s failure to insist upon strict performance of any covenant of this lease or to exercise
any option or right herein contained shall not be a waiver or relinquishment of the future of such covenant, right or action, but the same shall remain in full force and effect. 
 I. Notwithstanding any of the remedies set forth above, if rent and/or any charges hereby reserved as rent shall remain unpaid on any day when the same
ought to be paid, or if an event of default occurs, Tenant hereby empowers any Prothonotary, Clerk of Court or attorney of any Court of Record to appear for Tenant in any and all actions which may be brought for possession or rent and/or the
charges, payments, costs and expenses reserved as rent, or agreed to be paid by the Lessee and/or to sign for Tenant an agreement for entering in any competent Court an amicable action or actions for the recovery of rent or other charges, payments,
costs and expenses, and for possession of the Property, and in said suit or suits or in said amicable action or actions to confess judgment against Tenant for possession and/or all or any part of the rent specified in this Lease and then unpaid
including, at Landlord’s option, the rent for the entire unexpired balance of the term of this Lease, and/or other charges, payments, costs and expenses reserved as rent or agreed to be paid by the Tenant, and for interest and costs together
with reasonable attorney’s fees. Such authority shall not be exhausted by one exercise thereof, but judgment may be confessed as aforesaid from time to time as often as any of said rent and/or other charges, payments, costs and expenses,
reserved as rent shall fall due or be in arrears, and such powers may be exercised as well after the expiration of the original term and/or during any extension or renewal of this Lease. The right to enter judgment against Tenant and to enforce all
of the other provisions of this Lease as set forth above may, at the option of Landlord, be applied to an assignee of this Lease and may be exercised by any assignee of the Lessor’s right, title and interest in this Lease. Tenant hereby waives
any requirements of any and all laws regulating the manner and/or form of such assignments thereby permitting any assignee of this Lease to confess judgment against it. 
 J. Notwithstanding any provision to the contrary in this Section 17, if there is an event of default as described in the first paragraph of this Section 17 during the initial term of this Lease, and the
default arises out of Tenant’s financial inability to continue in business, then (a) Tenant shall have the right to terminate this Lease, (b) Landlord shall retain as liquidated damages good title to all of the tangible personal
property, fixtures and equipment described in Exhibit “A,” (c)

 
Tenant’s option in Section 3 shall expire automatically, and Section 3 shall have no further force or effect and (d) neither party shall
have any liability to the other arising out of the termination. The liquidated damages described in this paragraph J shall be Landlord’s sole remedy. This paragraph J shall be of no further force or effect at the end of the initial term of this
Lease. 
 K. In any amicable action for confession of judgment for possession and/or rent in arrears, Landlord shall first cause to be filed
in such action, a verified Complaint made by Landlord or its agent or attorney acting on its behalf, setting forth the facts necessary to authorize the entry of judgment, of which such Complaint and verification shall be conclusive evidence and if a
copy of this Lease shall be attached to such Complaint and filed in such action, it shall not be necessary to file the original Lease as a warrant of attorney, any rule of Court, custom or practice to the contrary notwithstanding. 
 18. Quiet Possession. 
 Landlord covenants and warrants that
upon performance by Tenant of its obligations hereunder, Landlord will keep and maintain Tenant in exclusive, quiet, peaceable and undisturbed and uninterrupted possession of the leased Property during the term of this Lease. 
 19. Condemnation. 
 If any legally, constituted authority
condemns the Building or such part thereof which shall make the leased Property unsuitable for leasing, this Lease shall cease when the public authority takes possession, and Landlord and Tenant shall account for rental as of that date. Such
termination shall be without prejudice to the rights of Landlord to recover compensation from the condemning authority for any loss or damage caused by the condemnation. Only Landlord shall have the right to pursue any claim against a condemning
authority for damages to or taking of the Property. 
 20. Subordination. 
 Tenant accepts this Lease subject and subordinate to any mortgage, deed of trust or other lien presently existing or hereafter arising upon the leased Property, or upon the Building and to any 

 
renewals, refinancing and extensions thereof, but Tenant agrees that any such mortgagee shall have the right at any time to subordinate such mortgage, deed
of trust or other lien to this Lease on such terms and subject to such conditions as such mortgagee may deem appropriate in its discretion. Landlord is hereby irrevocably vested with full power and authority to subordinate this Lease to any
mortgage, deed of trust or other lien now existing or hereafter placed upon the leased Property of the Building, and Tenant agrees upon demand to execute such further instruments subordinating this Lease or attorning to the holder of any such liens
as Landlord may request. In the event that Tenant should fail to execute any instrument of subordination herein required to be executed by Tenant promptly as requested, Tenant hereby irrevocably constitutes Landlord as its attorney-in-fact to
execute such instrument in Tenant’s name, place and stead, it being agreed that such power is one coupled with an interest. Tenant agrees that it will from time to time upon request by Landlord execute and deliver to such persons as Landlord
shall request a statement in recordable form certifying that this Lease is unmodified and in full force and effect (or if there have been modifications, that the same is in full force and effect as so modified), stating the dates to which rent and
other charges payable under this Lease have been paid, stating that Landlord is not in default hereunder (or if Tenant alleges a default stating the nature of such alleged default) and further stating such other matters as Landlord shall reasonably
require. 
 21. Security Deposit. Any security deposit required hereunder, shall be held by Landlord without liability for interest and as
security for the performance by Tenant of Tenant’s covenants and obligations under this Lease, it being expressly understood that the security deposit shall not be considered an advance payment of rental or a measure of Landlord’s damages
in case of default by Tenant. Unless otherwise provided by mandatory non-waivable law or regulation, Landlord may commingle the security deposit with Landlord’s other funds. Landlord may, from time to time, without prejudice to any other
remedy, use the security deposit to the extent necessary to make good any arrearages of rent or to satisfy any other covenant or obligation of Tenant hereunder. Following any such application of the security deposit, Tenant shall pay to Landlord on
demand the amount so applied in order to restore the security deposit to its original amount. If Tenant is not in default at the termination of this Lease, the balance of the security deposit remaining after any such application shall be returned by
Landlord to Tenant. If Landlord transfers its interest in the Property during the term of this Lease, Landlord may assign the security deposit to the transferee and thereafter shall have no further liability for the return of such security deposit.

 22. Notice. 
 Any notice required or permitted under this Lease shall be deemed sufficiently given if served by hand delivery or by overnight courier service or other method of personal delivery or if sent by United States certified mail, return receipt
requested, addressed as follows:

	1.	*** Base Year Formula. 

 Airframe and Optional Features price
adjustments (Airframe Price Adjustment) are used to allow prices to be stated in current year dollars at the signing of this Purchase Agreement and to adjust the amount to be paid by Customer at delivery for the effects of
economic fluctuation. The Airframe Price Adjustment will be determined at the time of Aircraft delivery in accordance with the following formula: 
  

	 	 Pa =
	 (P)(L + M) - P 

 Where: 
  

	 	 Pa =
	 Airframe Price Adjustment.  

	 	P =	Airframe Price plus the price of the Optional Features (as set forth in Table 11 of this Purchase Agreement).  

	 	L =	.65 x (ECI 

	 	    	          ECIb) 

 Where:

 ECIb is the base year airframe escalation index (computed as the three month arithmetic average value of 103.1 for June, July and August of *** as set forth in Table 11 of
this Purchase Agreement); 
 ECI is a value determined using the U.S.
Department of Labor, Bureau of Labor Statistics, Employment Cost Index for NAICS Manufacturing – Total Compensation (BLS Series ID CIU2013000000000I), calculated by establishing a three-month arithmetic average value (expressed as a decimal and
rounded to the nearest tenth) using the values for the 11th, 12th, and 13th months prior to the month of scheduled delivery of the applicable Aircraft. As the Employment Cost Index
values are only released on a quarterly basis, the value released for the first quarter will be used for the months of January, February, and March; the value released for the second quarter will be used for the months of April, May, and June; the
value released for the third quarter will be used for the months of July, August, and September; the value released for the fourth quarter will be used for the months of October, November, and December. 
 M = .35 x (CPI 
                   CPIb)

 Where: 
 CPIb is the base year airframe escalation index (computed as the three
month arithmetic average value of 208.2 for June, July and August of *** as set forth in Table 11 of this Purchase Agreement); and 
 CPI is a value determined using the U.S. Department of Labor, Bureau of Labor Statistics,
Consumer Price Index – All Urban Consumers (BLS Series ID CUUR0000SA0), calculated as a three (3) month arithmetic average of the released monthly values (expressed as a decimal and rounded to the nearest tenth) using the values for the 11
th, 12th, and 13th months prior to the month of scheduled delivery of the applicable Aircraft. 
 As an example, for an Aircraft scheduled to be delivered in the month of July, the months of June, July, and August of the preceding year will be utilized in determining the value of ECI and CPI. 
  

					
	Note:	  	i.	  	In determining the values of L and M, all calculations and resulting values will be expressed as a decimal rounded to the nearest ten-thousandth.
			
		  	ii.	  	.65 is the numeric ratio attributed to labor in the Airframe Price Adjustment formula.
			
		  	iii.	  	.35 is the numeric ratio attributed to materials in the Airframe Price Adjustment formula.
			
		  	iv.	  	The denominators (base year indices) are the actual average values reported by the U.S. Department of Labor, Bureau of Labor Statistics. The actual average values are calculated as a
3-month arithmetic average of the released monthly values (expressed as a decimal and rounded to the nearest tenth) using the values for the 11th, 12th, and 13th months prior to the airframe base year. The applicable base year and corresponding
denominator is provided by Boeing in Table 11 of this Purchase Agreement.
			
		  	v.	  	The final value of Pa will be rounded to the nearest dollar.
			
		  	vi.	  	The Airframe Price Adjustment will not be made if it will result in a decrease in the Aircraft Basic Price.

	2.	Values to be Utilized in the Event of Unavailability. 

 2.1 If the Bureau of Labor Statistics substantially revises the methodology used for the determination of the values to be used to determine the ECI and CPI values (in contrast to benchmark adjustments or other corrections of previously
released values), or for any reason has not released values needed to determine the applicable Airframe Price Adjustment, the parties will, prior to the delivery of any such Aircraft, select a substitute from other Bureau of Labor Statistics data or
similar data reported by non-governmental organizations. Such substitute will result in the same adjustment, insofar as possible, as would have been calculated utilizing the original values adjusted for fluctuation during the applicable time period.
However, if within 24 months after delivery of the Aircraft, the Bureau of Labor Statistics should resume releasing values for the months needed to determine the Airframe Price Adjustment, such values will be used to determine any increase or
decrease in the Airframe Price Adjustment for the Aircraft from that determined at the time of delivery of the Aircraft. 
 2.2
Notwithstanding Article 2.1 above, if prior to the scheduled delivery month of an Aircraft the Bureau of Labor Statistics changes the base year for determination of the ECI and CPI values as defined above, such re-based values will be incorporated
in the Airframe Price Adjustment calculation. 
 2.3 In the event escalation provisions are made non-enforceable or otherwise rendered void
by any agency of the United States Government, the parties agree, to the extent they may lawfully do so, to equitably adjust the Aircraft Price of any affected Aircraft to reflect an allowance for increases or decreases consistent with the
applicable provisions of paragraph 1 of this Supplemental Exhibit AE1 in labor compensation and material costs occurring since August of the year prior to the price base year shown in the Purchase Agreement. 
 2.4 If within twelve (12) months of Aircraft delivery, the published index values are revised due to an acknowledged error by the Bureau of Labor
Statistics, the Airframe Price Adjustment will be re-calculated using the revised index values (this does not include those values noted as preliminary by the Bureau of Labor Statistics). A credit memorandum or supplemental invoice will be issued
for the Airframe Price Adjustment difference. Interest charges will not apply for the period of original invoice to issuance of credit memorandum or supplemental invoice.

	Note:	  	i.	  	The values released by the Bureau of Labor Statistics and available to Boeing 30 days prior to the first day of the scheduled delivery month of an Aircraft will be used to determine the ECI and
CPI values for the applicable months (including those noted as preliminary by the Bureau of Labor Statistics) to calculate the Airframe Price Adjustment for the Aircraft invoice at the time of delivery. The values will be considered final and no
Airframe Price Adjustments will be made after Aircraft delivery for any subsequent changes in published Index values, subject always to Paragraph 2.4 above.
			
		  	ii.	  	The maximum number of digits to the right of the decimal after rounding utilized in any part of the Airframe Price Adjustment equation will be 4, where rounding of the fourth digit will be
increased to the next highest digit when the 5th digit is equal to 5 or greater.
