 You have been awarded the above number of restricted stock units (the “Stock Units”) under the 2006 Stock Incentive Plan (the “Plan”)
of NCR Corporation (“NCR”), subject to the terms and conditions of this 2007 Director Restricted Stock Unit Grant Statement (this “Statement”) and the Plan. 
 1. The Stock Units will vest during the one (1) year period beginning on the date upon which
you were granted the Stock Units (the “Grant Date”), in four (4) equal quarterly installments commencing three (3) months after the Grant Date, provided that you continuously serve as a Director of NCR until each quarterly
vesting date. Notwithstanding the foregoing, if the Grant Date of your Stock Units is the date of an Annual Meeting of Stockholders, then, the fourth quarterly vesting will occur only if you continue to serve as a Director until the earlier of
(a) the next Annual Meeting of Stockholders following the Grant Date, or (b) the first (1st) anniversary of the Grant Date. 
 2. The Stock Units will become fully vested if, prior to the one (1) year
anniversary of the Grant Date, you die at a time while serving as a Director of NCR. 
 3. The vesting schedule will accelerate and the Stock
Units will become fully vested if (1) a Change in Control (as defined in Section 10(b) of the Plan) occurs, and (2) you cease to serve as a Director of NCR within twenty-four (24) months of the effective date of the Change in
Control for any reason other than your willful engaging in illegal conduct or gross misconduct, as determined by the affirmative vote of a majority of the entire membership of the Board of Directors of NCR. 
 4. When vested, the Stock Units will be paid to you in shares of NCR common stock, such that one Stock Unit equals one share of NCR common stock.

 5. Any cash dividends declared before your Vesting Dates on the shares underlying the Stock Units shall not be paid currently, but shall
be converted to additional Stock Units, based on the fair market value of NCR common stock on the date the dividend is declared. Any Stock Units resulting from such conversion will be considered Stock Units for purposes of this Statement and will be
subject to all of the terms, conditions and restrictions set forth herein. 
 6. You may designate one or more beneficiaries to receive all
or part of any shares underlying the Stock Units to be distributed in case of your death, and you may change or revoke such designation at any time. In the event of your death, any shares underlying the Stock Units distributable hereunder that are
subject to such a designation will be distributed to such beneficiary or beneficiaries 

 
in accordance with this Statement. Any other shares underlying the Stock Units not designated by you will be distributable to your estate. If there shall be
any question as to the legal right of any beneficiary to receive a distribution hereunder, the shares underlying the Stock Units in question may be transferred to your estate, in which event NCR will have no further liability to anyone with respect
to such shares. 
 7. The terms of this award of Stock Units as evidenced by this Statement may be amended by the NCR Board of Directors or
the Compensation Committee of the NCR Board of Directors, provided that no such amendment shall impair your rights hereunder without your consent. 
 8. In the event of a conflict between the terms and conditions of this Statement and the terms and conditions of the Plan, the terms and conditions of the Plan shall prevail.Fourth Amendment to the NCR Nonqualified Excess Plan

 Exhibit 10.11 
 FOURTH AMENDMENT 
 TO THE NCR NONQUALIFIED EXCESS PLAN 
 AMENDMENT TO THE NCR NONQUALIFIED EXCESS PLAN (the “Plan”) as restated and in effect January 1, 1996 by NCR Corporation (“NCR”).

 WHEREAS, the Plan was amended and restated effective January 1, 1996, and amended by a First Amendment effective September 1,
2004, to admit no new participants in the Plan and cease benefit accruals for all participants other than a grandfathered group, a Second Amendment effective January 1, 2006, and a Third Amendment effective December 31, 2006; and

 WHEREAS, NCR desires to amend the Plan to permit participants who are employees of Teradata Corporation immediately after the spin-off

“Spin-Off”) to receive credit for their service with Teradata Corporation after the Spin-Off for purposes of determining whether such participants have satisfied the requirement for a benefit under the Plan that they terminate employment
from the Company at or after age 55; 
 NOW, THEREFORE, NCR does hereby amend the Plan, effective as of the effective time of the Spin-Off,
as follows: 
 A new sentence is added at the end of Section 2.1 of the Plan providing as follows: 
 For the purpose of determining whether a participant who was an employee of the Company or Teradata Corporation immediately prior to the spin-off of Teradata Corporation
by the Company (the “Spin-Off”) and an employee of Teradata Corporation immediately after the Spin-Off (or, pursuant to the terms of a Transition Services Agreement between NCR and Teradata Corporation, are transferred to Teradata
Corporation at the conclusion of the transition services period), terminates from the Company at or after age 55, as required by the preceding sentence, such participant shall not be deemed to have terminated from the Company until the earlier of
the date on which the participant terminates from Teradata Corporation or the date on which Teradata Corporation ceases to be a separate publicly-held corporation, or, if the participant returns to the Company from Teradata Corporation without
incurring a break in service, the date on which the participant subsequently terminates from the Company. 

 IN WITNESS WHEREOF, NCR has caused this amendment to the Plan to be executed this second day of May,

	 Article 6.
	 Taxes and Duties

agency on HNS’s behalf, a portion of the payment of the Purchase Price for income tax withholding imposed on HNS related to the Work performed in Canada (the “105 Withholding”), TerreStar shall withhold such 105 Withholding and not be
required to “gross up” or otherwise reimburse HNS for the amount of such 105 Withholding, provided however, if applicable, TerreStar agrees to reduce the 105 Withholding in accordance with a waiver (“105 Waiver”) issued by the
Canada Revenue Agency, in respect of payments that are subject to 105 Withholding that are made following TerreStar ‘s receipt of such 105 Waiver. 
 D. “Excluded Taxes” means any Taxes described as excluded from the Purchase Price or for which TerreStar is otherwise responsible in this Article 6. 
 E. The Purchase Price shall not include, and TerreStar shall be responsible for paying, either directly to the governmental agency or as billed by Contractor: 
  

	 	 (1)
	 any and all consumption Taxes imposed on the sale, delivery and installation of the Deliverable Items (“Consumption Taxes”) by any United States
federal, state, or local government, and 

  

	 	 (2)
	 any and all Consumption Taxes imposed by any Canadian federal or provincial government with respect to this contract, (including, if applicable, Canadian GST,
HST and/or PST). 

 F. All Taxes billed by Contractor shall be separately stated on the applicable invoice. 
 G. TerreStar shall withhold any Taxes from payments to Contractor as required by law. 
 H. The Parties shall cooperate to minimize all Taxes, including but not limited to the following: 
  

	 	 (1)
	 Contractor will take all steps within its control that are necessary to ensure that all applicable exemptions and tax credits in respect of the Deliverable Items
are available to TerreStar, and Contractor will cause any subcontractor to also take all such steps, and

	 	 (2)
	 TerreStar will take all steps within its control and not otherwise available to Contractor that are necessary to ensure that all applicable exemptions and tax
credits in respect of the Deliverable Items are available to Contractor. 

 I. Subject to the indemnification procedures
set forth in Article 15.C, in the event any governmental or taxing authority imposes or assesses Taxes against a Party hereto for which the other Party is responsible pursuant to this Article 6, the responsible Party shall indemnify the other Party
for Taxes paid by the Party entitled to indemnification and shall reimburse such Party for related costs of defense (whether or not such Party actually pays the subject Taxes). The Party that is assessed will take all reasonable steps to defend any
such assessment. The responsible Party will be entitled to be promptly notified of any assessment and to all reasonable information related to the assessment of Taxes, and, at its option and expense, may assume control of any defense or submission
in respect of the assessed Taxes. 
 J. The Parties agree to designate herein the value of the goods delivered to, and the services performed
in, Canada as soon as reasonably practicable. 
  

	 Article 7.
	 Payment Terms 

 A.
Payment Schedule. For each Milestone, TerreStar shall make the milestone payment, to the account specified by Contractor, associated with such Milestone (as set forth in Exhibit C), if any, once TerreStar has performed any applicable testing
and has confirmed that Contractor has successfully completed all of the Work associated with such Milestone. 
 B. Milestone Payments.
Contractor shall submit an invoice to TerreStar once TerreStar has confirmed in writing that the Work associated with such Milestone has been successfully completed. Each invoice shall contain or be accompanied by a written certification from
Contractor that the Milestone has been completed and confirmed by TerreStar. 
 C. Payment Conditions. Subject to Article 7.D below,
TerreStar shall pay each undisputed invoiced amount within thirty (30) days after TerreStar receives the invoice and certification; provided, however, that if TerreStar reasonably concludes that the requirements for the applicable Milestone
have not been fulfilled, then TerreStar shall so notify Contractor in writing, including a description of TerreStar’s basis for asserting that the Milestone has not been fulfilled. In such event the applicable payment shall not become due until
thirty (30) days after TerreStar has determined that the requirements for such Milestone have been fulfilled. 
 D. No Early

elects to do so, TerreStar will notify Contractor of such dispute prior to the original payment due date, with such notice specifying the reasons for the dispute. Failure of TerreStar to withhold payment or to make any such notification shall not be

 B.
Contractor Warranties. Notwithstanding any prior inspection or acceptance by TerreStar, Contractor warrants that: 
 (1) All Deliverable Items, including without limitation deliverable equipment and software, shall be new, and not refurbished or remanufactured, when first delivered to TerreStar and, without limiting Article 9.J, a shall be free from any
defects in materials, workmanship and design through the Warranty Period and shall conform to the Specifications set forth in this Contract and Exhibit B hereto;

the Work is non-conforming. The notice shall identify those particulars in which the Work fails to conform. 
 (1) Non-Conformance or Defect. Any non-conformance or defect discovered in a Deliverable Item notified to Contractor during the
Warranty Period shall be remedied by Contractor at Contractor’s expense by repair or replacement of the defective component (at Contractor’s election). For any such Deliverable Item, Contractor shall determine if correction, repair or
replacement is required to be performed at Contractor’s plant. If required, TerreStar shall ship to Contractor’s designated facility any such Deliverable Item in accordance with Article 9.C(2). If returning a component for repair is not
commercially practical, Contractor shall repair the defective component on site, at Contractor’s expense, including travel expenses. If Contractor is required to repair a particular component or subassembly of any Deliverable Item more than
three (3) times in any rolling twelve (12)-month period, Contractor shall replace such defective component or subassembly in its entirety at no additional charge. Contractor shall promptly re-perform any non-conforming Services brought to
Contractor’s attention during the Warranty Period at Contractor’s expense. If Contractor does not correct or replace a defective Deliverable Item or re-perform non-conforming Services, in either case, within ten (10) days after
notification from TerreStar (which shall be extended to a thirty (30) day cure period if such repair or replacement is not feasible within the ten (10) day period, provided that Vendor makes substantial progress in remedying the defect
within the ten (10) day period), or if Contractor fails to do so effectively, TerreStar may have the correction or replacement or re-performance undertaken by a third party, in which case Contractor shall reimburse TerreStar for all direct
reprocurement costs reasonably and actually incurred by TerreStar. 
 (2) Return Shipping. Contractor shall be
responsible for the cost of shipment (including transportation, transit insurance, taxes and duties) of any such Deliverable Item to Contractor’s facility, and the cost of packing and return shipment (including transportation and transit
insurance) of any such Deliverable Item, once repaired or replaced, to TerreStar at the location designated by TerreStar. Risk of loss for such Deliverable Item shall transfer to Contractor upon delivery by TerreStar of such Deliverable Item to the
shipping carrier, and risk of loss shall transfer back to TerreStar for any such Deliverable Item once properly re-installed on-site at the applicable S-BSS location. 
 (3) TerreStar’s Election. TerreStar may elect not to have the defective or non-conforming Work corrected, re-performed or replaced, in which case the Parties shall in good faith
negotiate an equitable reduction in the price and, to the extent TerreStar has already made payments in excess of the reduced price, Contractor shall promptly refund that amount. 
 D. Warranty Period. With respect to each Deliverable Item or Service , these warranty and support obligations shall run for a period of one (1) year from the completion of Technical
Verification Review for Release 2 (the “Warranty Period”). Notwithstanding the preceding, as part of the Services included in the Purchase Price, Contractor shall remedy any problems or defects in Release 1 that arise between Provisional
Acceptance and Final Acceptance. 
 E. Title and Risk of Loss of Replacements. Any corrections or replacements made pursuant to this
Article 9 shall be subject to Article 8.A. With respect to any Deliverable Item that is corrected or replaced, the Warranty Period specified in this Article shall be suspended from the date of notification of the defect by TerreStar and shall
recommence upon the date of satisfactory completion and delivery of the correction or replacement for the unexpired portion of the Warranty Period (as extended by an amount equal to the duration of the suspension). Where such correction or
replacement renders the Deliverable Item or any part thereof non-functional, the Warranty Period shall be similarly extended for the Deliverable Item or any part thereof.

 F. Spare Parts. Contractor
shall provide TerreStar with a plan for obtaining and maintaining spare parts, including a list of all mission-critical replacement level parts. Such plan shall take into account both the delivery times for limited source and long-lead items. Such
plan shall be subject to TerreStar’s review and approval. During the Warranty Period, Contractor shall maintain and replenish a spare parts inventory in accordance with such plan at Contractor’s expense. At the end of the Warranty Period,
the spare parts inventory shall be fully-replenished by Contractor at its expense. After the Warranty Period, and for a period of seven (7) years from Final Acceptance, at TerreStar’s request, Contractor shall sell additional spare parts
(those not included in the then-current replenished spare parts inventory) to TerreStar and/or its service providers on commercially reasonable terms and prices. Any other item, component or part supplied as a spare part by Contractor shall be
warranted in accordance with this Article for a period of one (1) year from the later of (i) the date of delivery to TerreStar or (ii) the end of the Warranty Period. If required, Contractor shall assist TerreStar to transition
responsibility for sourcing spare parts for the S-BSS after the end of such seven (7)-year period. 
 G. Software Warranty. In
addition to the general warranty obligations set forth above, throughout the Warranty Period, Contractor shall correct all software errors and bugs, and provide any patches and updates to bring the software in conformance with Exhibit A and any
applicable Specifications (collectively, “Software Corrections”), and Contractor shall make all upgrades, enhancements and releases of the software (collectively, “Software Updates”) available to TerreStar at no additional charge
during the Warranty Period, and thereafter at a commercially reasonable price. Such Software Corrections and Software Updates shall be tested to TerreStar’s satisfaction prior to release. 
 H. No Virus. Contractor warrants that no code, device or routine (including, without limitation, time bombs, back doors or drop dead devices) that would have the effect of disabling or
otherwise shutting down all or any portion of any software comprising any portion of any Deliverable Item (“Viruses”) is coded or introduced into any Deliverable Item any time prior to Final Acceptance (unless TerreStar expressly
authorizes the inclusion of a disabling code). If a Virus is present in any portion of any Deliverable Item prior to or during the Warranty period and it is determined that the introduction of the Virus was attributable to Contractor, Contractor
shall assist TerreStar in removing or reducing the effects of the Virus, and assist TerreStar with mitigating and restoring any such losses of operational efficiency or data that arise as a result of the Virus, all at Contractor’s expense. In
no event shall Contractor invoke any Virus or disabling code at any time, including upon expiration or termination of the Contract (in whole or in part) for any reason, without TerreStar’s prior written consent. 
 I. Deliverable Data and Documentation. Contractor warrants that each item of data and documentation delivered under the Contract shall be
complete, correct and up to date, and shall otherwise conform to the requirements of this Contract. Contractor shall provide a correction to any data and documentation when Contractor is notified or otherwise becomes aware of any such defect.

 J. Latent Defects. Contractor further warrants the Deliverable Items against Latent Defects for a period of four (4) years
after the applicable Warranty Period. 
 K. Title. Contractor represents and warrants it shall provide good and salable in-commerce
title to all Deliverable Items, free and clear of any liens, security interest, claims or any other encumbrances of any kind, at the time title passes to TerreStar pursuant to Article 8 hereof. 
 L. Intellectual Property. Contractor represents and warrants that as of EDC, Contractor is not aware of any claim that the Work or any
Intellectual Property owned or supplied by Contractor utilized or incorporated in any Deliverable Item or the manufacture of any Deliverable Item infringes any Intellectual Property Right of any third party. This warranty shall continue for the
operating life of the S-

BSS. TerreStar shall not be required to pay any license fees or royalties apart from those included in the Purchase Price for use of any Intellectual
Property utilized or incorporated in any Deliverable Item or the manufacture of any Deliverable Item. 
 M. Expeditious Remediation.
Contractor shall perform its obligation under this Article in an expeditious manner so as to minimize any interruption or risk of interruption to the functioning of the TerreStar Network, and Contractor shall take all such actions as are required to
restore functionality to the S-BSS so that it complies with the Specifications set forth in this Contract and Exhibit B hereto. 
 N.
Pass-Through Warranties. Without limiting Contractor’s warranty obligations, to the extent that Contractor has been given the right within its agreements, Contractor shall pass through to TerreStar the benefits of any warranties to which
Contractor is entitled to by virtue of Contractor’s purchase of S-BSS equipment, software, supplies or services from the manufacturers, subcontractors, suppliers, lessors or licensors of such items. 
 O. Limitation. EXCEPT WITH RESPECT TO ARTICLES 9.K AND 9.L, THE RIGHTS AND REMEDIES OF TERRESTAR PROVIDED IN THIS ARTICLE 9 SHALL BE THE SOLE AND
EXCLUSIVE REMEDY, EXPRESS OR IMPLIED, WHETHER PURSUANT TO THIS CONTRACT OR OTHERWISE, WITH RESPECT TO THIS ARTICLE 9. 
 P.
Disclaimer. EXCEPT AS SPECIFICALLY SET FORTH IN THIS CONTRACT, CONTRACTOR NEITHER MAKES NOR ASSUMES ANY LIABILITY UNDER ANY WARRANTIES (WHETHER EXPRESS, IMPLIED, OR STATUTORY) ON OR WITH RESPECT TO CONTRACTOR DELIVERABLE ITEMS AND SERVICES TO
BE PROVIDED UNDER THIS CONTRACT, INCLUDING, WITHOUT LIMITATION, ANY IMPLIED CONDITIONS OR WARRANTIES OF MERCHANTABILITY, NON-INFRINGEMENT, OR FITNESS FOR A PARTICULAR PURPOSE. The limited warranties set forth in this Article 9 will not apply with
respect to (i) equipment that has been subject to unauthorized alteration, modification, or repair; (ii) defects or failures resulting from improper handling, storage, operation, interconnection, or installation; (iii) failure to
continually provide a suitable installation and operational environment; or (iv) any other cause beyond the range of normal usage for the equipment (except, in all of the foregoing cases, when caused by Contractor, Contractor subcontractors or
Contractor agents). 
 Q. Quality Assurance. Within three (3) months after EDC, the Parties shall develop and agree upon a
written quality assurance program and procedure that will apply to this Contract (“the Quality Assurance Program”). Contractor shall maintain compliance with the ISO 9001 series approach to quality in the performance of all of its
obligations under the Contract. If Contractor fails to either implement or follow the Quality Assurance Program, TerreStar may, in its discretion, suspend Contractor’s production and other activities until the date when the Quality Assurance
Program is properly implemented and followed. Contractor’s work stoppage pursuant to this Article 9.Q shall not relieve Contractor of its obligation to comply with the Milestone Schedule and other scheduling requirements in this Contract.

 R. Post-Warranty Support. Contractor shall use commercially reasonable efforts to ensure that post-warranty hardware and software
support may be procured from Contractor for the S-BSS, on commercially reasonable terms and pricing, for a period of seven (7) years from Final Acceptance. 
 S. Source Code. Contractor shall place the source code of any software licensed to TerreStar or used in the operations and maintenance of the S-BSS in escrow for release to TerreStar or its designee upon the
occurrence of certain agreed upon events, including the failure of Contractor to maintain and support the software as set forth in the Contract, discontinuance of maintenance and support for the

software or the insolvency or bankruptcy of Contractor or termination of this Contract by TerreStar for Contractor default in accordance with
Section 19.A. TerreStar shall be responsible for its allocable share of all fees charged by the escrow agent in setting up and maintaining the escrow account. 
  

	 Article 10.
	 Personnel and Key Personnel 

 A. Personnel Qualifications. Contractor shall ensure that its personnel (including Subcontractor personnel) are fully qualified and have in place all the research, development, manufacturing, technological and management skills
necessary to perform the Work. If TerreStar, in good faith determines that the continued assignment of any Contractor personnel is not in TerreStar’s best interest, then TerreStar shall provide Contractor written notice to that effect
requesting that such personnel be replaced. Promptly after receipt of such request, Contractor shall investigate the matters stated in the request and discuss its findings with TerreStar. If TerreStar still requests replacement of the personnel,
Contractor shall so replace such personnel with an individual satisfactory to TerreStar. 
 B. Minimizing Turn-Over Rate. Contractor
shall use best reasonable efforts to retain the same personnel on TerreStar’s program for the duration of Contractor’s performance of this Contract. The Parties both agree that it is in their best interests to maintain a low turnover rate
of Contractor personnel. If TerreStar determines that Contractor personnel turnover rate is excessive, TerreStar shall notify Contractor, and the Parties shall meet to discuss the general reasons for the turnover rate, and if applicable, the Parties
shall mutually agree on a program to reduce the turnover rate to an acceptable level. In no event, however, shall such turnover rate affect Contractor’s obligations to perform under the Contract. 
 C. Key Personnel. Key personnel (“Key Personnel”) shall be the personnel filling the following or equivalent positions: 
  

	 	 (1)
	 Contractor Program Manager; [***] 

  

	 	 (2)
	 Engineering Manager; [***] 

 D.
Assignment of Key Personnel. 
 (1) Qualifications. Contractor will assign individuals from within
Contractor’s organization to the Key Personnel positions to carry out the Work. Key Personnel will be familiar with programs similar to TerreStar’s program. 
 (2) Review and Approval. Prior to their assignment, Contractor shall submit a list of dedicated Key Personnel and their respective assignments within the TerreStar program, along with a
resume of such key personnel and any other information reasonably requested by TerreStar necessary for evaluating the qualifications of such Key Personnel. If TerreStar in good faith objects to the qualifications of the proposed individual within
fifteen (15) Business Days after being notified thereof, then Contractor agrees to discuss such objections with TerreStar and attempt to resolve such concerns on a mutually agreeable basis or, if unable to resolve the matter, Contractor shall
select another candidate acceptable to TerreStar. Contractor shall not assign any individual rejected by TerreStar to the TerreStar program. 
 Should the individuals filling the positions of Key Personnel leave such positions for whatever reason, Contractor shall follow the procedures set forth in this Article 10 to select replacement personnel and shall provide TerreStar with a
proposed transition plan for such replacement.

 (3) Commitment to
Program. Key Personnel shall not be removed from the TerreStar program without TerreStar’s prior written consent (except in the event such person is no longer employed by Contractor). Contractor shall, to the extent possible, notify
TerreStar of its intent to replace any Key Personnel, and shall provide TerreStar with its proposed replacement Key Personnel and a proposed transition plan, both subject to TerreStar’s approval. 
 E. Program Managers. Each Party shall appoint an executive to act as program manager having the primary responsibility for performance of its
company’s obligations hereunder and for managing the relationship between the Parties (the “Contractor Program Manager” or the “TerreStar Program Manager”, as the case may be). Each Party also shall identify a primary
contact who shall serve as the point of contact for all day-to-day and operational issues. 
  

	 Article 11.
	 Major Subcontracts 

 A.
Selection of Major Subcontractors. Selection and engagement of any Major Subcontractor, whether as an initial selection or as a replacement selection, shall be subject to TerreStar’s prior written approval, not to be unreasonably
withheld. Contractor shall provide TerreStar with a copy of the full text of any agreement of any Major Subcontract (including technical content but excluding price and payment schedule) promptly upon execution thereof. Contractor shall be fully
responsible for the acts and omissions of any Subcontractor hereunder. 
 TerreStar’s approval of any Major Subcontractor or
subcontractor shall not relieve Contractor from any obligations or responsibilities under this Contract. 
 B. Step-In Payment Rights.
Contractor shall notify TerreStar within five (5) Business Days of it becoming aware of the occurrence of an event that with or without the passage of time or the giving of notice, or both, would give rise to a right of termination or a right
to receive damages or a payment of penalties under any of Contractor’s Major Subcontracts that Contractor is not then disputing, in good faith, with such Major Subcontractor (a “Subcontractor Default”). TerreStar shall have the right
(but not the obligation) to cure any such Subcontractor Default, including by making any payment due thereunder. The Purchase Price shall be reduced by the amount of the cost to cure such Subcontractor Default paid by TerreStar pursuant to the
preceding sentence. Such reduction in the Purchase Price shall be applied against and used to reduce the next payment due to Contractor under the Milestone Schedule (which shall be adjusted accordingly). No action on the part of TerreStar under this
Article shall relieve Contractor from any obligations or responsibilities under this Contract or the Major Subcontract. 
 C. No Privity
of Contract. Nothing in this Contract shall be construed as creating any contractual relationship between TerreStar and any Major Subcontractor or subcontractor. Contractor is fully responsible to TerreStar for the acts or omissions of Major
Subcontractors and subcontractors and all persons used by Contractor or a Major Subcontractor or subcontractor in connection with performance of the Work. Any failure by a Major Subcontractor or subcontractor to meet its obligations to Contractor
shall not constitute a Force Majeure Event, except as provided in Article 19, and shall not relieve Contractor from meeting any of its obligations under this Contract. 
  

	 Article 12.
	 Access to Works in Process 

 A. General. Subject to Article 22, Contractor shall afford TerreStar with full and complete access, during normal working hours and subject to TerreStar providing Contractor with reasonable advance notice, to the Work and all
work-in-process (including any associated raw materials, works-in-process and partially finished goods) (collectively, “Works-in-Process”) to be provided to TerreStar under this

promptly remedy that situation. 
 B. Works-in-Process at Contractor’s Facility. Subject to Article 22 and compliance with
Contractor’s normal and customary safety and security policies and procedures (as enforced by Contractor with respect to its own employees) of which TerreStar has received prior written notice (including a copy of such policies and procedures),
TerreStar personnel shall be allowed access to all Work and Works-in-Process being performed at Contractor’s facility for the purpose of observing the progress of such Work at all times. Subject to Article 22, TerreStar shall be provided with a
reasonable number (not to exceed ten (10)) non-escort permanent badges and with a reasonable number (not to exceed ten (10)) escort badges to work areas where the Work is being performed. 
 C. Works-in-Process at Subcontractors’ Facilities. In the case of Contractor’s Major Subcontracts, Contractor shall require that each
such Major Subcontract contain a provision substantially similar to this Article 12 with respect to TerreStar’s access to the applicable Major Subcontractor’s facilities and performance of the Work, including the provision to TerreStar of
two (2) non-escort permanent badges and two (2) escort badges to work areas where the Work is being performed. 
 D. On-Site
Facilities for TerreStar’s Personnel. For the purpose of monitoring the progress of the Work being performed by Contractor hereunder, Contractor shall provide office facilities at or proximate to Contractor’s plant for up to two

telephone usage, internet access (at the same speed and quality available to Contractor personnel), electronic access to Contractor’s exchange network specific to this Contract, access to copy machines, facsimile machines, meeting rooms, car
parking facilities and to the extent available, videoconference rooms, to enable TerreStar personnel to monitor the progress of Work under this Contract. In the case of Contractor’s Subcontracts, Contractor shall use commercially reasonable
efforts to ensure that reasonable office facilities, consistent with the Specifications described above, for up to two (2) TerreStar personnel are provided through the completion of the Subcontract. 
 E. Interference with Operations. TerreStar shall exercise its rights under this Article 12 in a manner that does not unreasonably interfere with
Contractor’s or its Subcontractors’ normal business operations or Contractor’s performance of its obligations under this Contract or any agreement between Contractor and its Subcontractors. 
 F. Financing Entities. Subject to the provisions of Article 22, each Financing Entity shall have escorted access to the Work in the same manner
and to the same extent as TerreStar personnel under Article 12.B and Article 12.C. 
 G. Access to Work Product. TerreStar may at any
time request, and Contractor shall promptly provide, complete and accurate copies of any work product created or performed by Contractor or its Subcontractors under this Contract including, but not limited to reports, designs, drawings, test,
results, bills of material, data software and source code, in accordance with Article 9-S (excluding source code that is Contractor Background IP or that is included in third party commercial-off-the-shelf software, and any other information
relating to commercial-off-the-shelf items that is not reasonably available to Contractor).

 A. Indemnification. Contractor, at its own expense, shall defend, or at its option settle, any claim, action or other proceeding brought against TerreStar and its Affiliates and their respective directors,
officers, employees, shareholders, and agents, based on allegations that any of the Deliverable Items, provided by Contractor hereunder infringes any patent, copyright, trade secret or other intellectual property right of a third party (“IP
Claim”), and shall indemnify and hold TerreStar harmless against all losses, damages, liabilities, expenses and costs (including reasonable attorneys’ fees) incurred by and/or awarded against TerreStar as a result of any such IP Claim. The
conditions to indemnification specified in Article 15.C shall apply as well to IP Claims subject to indemnification as described in this paragraph. 
 B. Exception. Contractor shall have no liability under this Article 14 for an IP Claim to the extent arising solely from: (i) use of any item provided by Contractor hereunder in combination with other items not provided,
recommended, or approved by Contractor, or its suppliers or Subcontractors or otherwise not used in the ordinary course with the accused Deliverable Item; or (ii) TerreStar modification of any Deliverable Item provided by Contractor hereunder
in a manner not intended or reasonably foreseeable by Contractor, except where such modification was made by or on behalf of TerreStar due to Contractor’s failure to perform a contractual obligation; or (iii) TerreStar’s failure to
employ modifications to a Deliverable Item made available by Contractor provided that after such modifications, the Deliverable Item would comply with the applicable specifications or other requirements under this Contract; or
(iv) Contractor’s compliance with TerreStar’s designs or specifications (where such designs or specifications form the basis for the IP Claim, and not Contractor’s chosen implementation), or 

  

 Page 15

Contractor’s incorporation of technology supplied or dictated by TerreStar (where such technology forms the basis for the IP Claim). 
 C. Additional Measures. If the use of any Deliverable Item or Service is enjoined based on any infringement action, in addition to indemnifying
TerreStar, Contractor shall, promptly at its own expense (i) resolve the matter so that the injunction or prohibition no longer pertains; (ii) procure for TerreStar the right to use the infringing item; and/or (iii) modify the
infringing item so that it becomes non-infringing while remaining in compliance with the Specifications set forth in this Contract and Exhibit B hereto. If Contractor is unable to accomplish (i), (ii) or (iii) as stated above,
Contractor shall meet with TerreStar, at TerreStar’s request, to address the matter and reach an equitable solution reasonably acceptable to TerreStar. If such discussions are not satisfactory to TerreStar, TerreStar shall have the right to
terminate this Contract in whole or in part, return such Deliverable Item(s) to Contractor, and receive a refund which shall equal TerreStar’s reasonable costs and expenses to replace the affected Deliverable Item or Services.

warranty, express or implied, with respect to any IP Claim.

 A. Contractor’s Indemnity. Contractor shall indemnify, defend and hold harmless TerreStar and its Affiliates, and their employees, officers, directors, agents and representatives from and against all claims, liability, loss,
damages, penalties, fines, costs and expense (including reasonable attorneys’ fees) (collectively, “Losses”) based on (i) claims or allegations of injury to persons or real or tangible personal property damage to the extent
caused by or resulting from a negligent act or omission or willful misconduct of Contractor or its employees, Subcontractors, agents or representatives; (ii) claims or allegations of Contractor’s failure to comply with applicable laws; and

representatives from and against all Losses based on claims or allegations of injury to persons or property damage to the extent caused by or resulting from a negligent act or omission or willful misconduct of TerreStar or its employees,
subcontractors, agents or representatives. 
 C. Conditions to Indemnification. The right to any indemnity set forth in this Contract
shall be subject to the following conditions: 
 (1) Notice. The Party seeking indemnification (the “Indemnified
Party”) shall promptly advise the other Party (the “Indemnifying Party”) in writing of the filing of any suit or of any written or oral claim for which it seeks indemnification upon receipt thereof and shall provide the Indemnifying
Party, at its written request, with copies of all documentation relevant to such suit or claim. Failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations under this Contract except to the extent it can
demonstrate that it was prejudiced by such failure. Within thirty (30) days following receipt of written notice from the Indemnified Party, but no later than a reasonable time before the date on which any response to a complaint or summons is
due, the Indemnifying Party shall notify the Indemnified Party in writing if the Indemnifying Party elects to assume control of the defense or settlement of that claim (a “Notice of Election”).

 Use or disclosure of the data contained on this sheet is subject to the restriction on the title page. 

 

 
  
 (2) Control of
Action. If the Indemnifying Party delivers a Notice of Election relating to any claim within the required notice period, so long as it is actively defending such claim, the Indemnifying Party shall be entitled to have sole control over the
defense and settlement of such claim; provided that (i) the Indemnified Party shall be entitled to participate in the defense of such claim and to employ counsel at its own expense to assist in the handling of such claim; (ii) where the
Indemnified Party is so represented, the Indemnifying Party shall keep counsel of the Indemnified Party informed of each step in the handling of any such claim; (iii) the Indemnified Party shall provide, at the Indemnifying Party’s request
and expense, such assistance and information as is available to the Indemnified Party for the defense and settlement of such claim; and (iv) the Indemnifying Party shall obtain the Indemnified Party’s approval, which shall not be
unreasonably withheld, delayed or denied, before entering into any non-monetary settlement of such claim or ceasing to defend against such claim. 
 (3) Right of Indemnified Party to Defend/Settle. If the Indemnifying Party does not deliver a Notice of Election relating to any claim within the required notice period or fails actively to defend such claim,
the Indemnified Party shall have the right to defend and/or settle the claim in such manner as it may deem appropriate, at the cost and expense of the Indemnifying Party. Provided that the Indemnified Party acts in good faith, it may settle such
claim on any terms it considers appropriate under the circumstances without in any way affecting its right to be indemnified hereunder. The Indemnifying Party shall promptly reimburse the Indemnified Party for all such costs and expenses.

 D. Waiver of Subrogation. Each Party shall use commercially reasonable efforts to obtain a waiver of subrogation and release of any
right of recovery against the other Party and its Affiliates, Contractors and Subcontractors at any tier (including suppliers of any kind) and their respective directors, officers, employees, shareholders and agents, that are involved in the
performance of this Contract from any insurer providing coverage for the risks such Party has agreed to indemnify against under this Article 15. 
  

	 Article 16.
	 TerreStar-Furnished Property and Facilities 

 A. All equipment or other property that is required to be furnished to Contractor by TerreStar pursuant to Exhibits A and B shall be in accordance with the terms and conditions therein. Failure or delay
of TerreStar to provide such equipment and/or property shall not constitute a breach of this Contract, but shall only excuse Contractor from the performance of its obligations under this Contract to the extent affected thereby. 
 B. The parties shall develop and mutually agree in good faith upon a “Facility Requirements Document” specifying the environmental and related
conditions that will be provided with respect to any facilities provided by TerreStar or any of its other contractors pursuant hereto, whether for installation of the items to be delivered by Contractor under this Contract or for any other purpose.
TerreStar shall exercise all reasonable care to ensure that the Deliverable Items to be located in any facility meet the requirements set forth in such “Facility Requirements Document.” 
 C. The late delivery of TerreStar furnished items (including the satellite) or services as required under this Article 16 or the Statement of Work, shall
be considered an event beyond the reasonable control of Contractor, and, except for delays resulting from a Force Majeure Event of less than ninety (90) days, if such late delivery has a material adverse impact on Contractor’s costs, the
Delivery Schedule or performance requirement, Contractor shall be entitled to an equitable adjustment in price, schedule, performance requirements and other terms of this Contract in accordance with Article 25.B(3).

	 Article 17.
	 Confidential Information 

 A. Definition of Confidential Information. 
 (1) Definition. For the purpose of this Contract,
“Confidential Information” means all confidential or proprietary information in whatever form, that is transmitted, disclosed or otherwise made available by such Party (hereinafter referred to as the “Disclosing Party”) to the
other Party hereto (hereinafter referred to as the “Receiving Party”) and: (i) is identified as proprietary or confidential by means of a written legend thereon, or (ii) if disclosed orally, is identified as proprietary or
confidential at the time of initial disclosure and then summarized in a written document, with the Confidential Information specifically identified, that is supplied to the Receiving Party within ten (10) days of initial disclosure. In the case
of either Party, Confidential Information also shall include, whether or not designated “Confidential Information,” (a) correspondence under this Contract and (b) all information concerning either Party (and/or its Affiliates)
regarding its operations, affairs and businesses, its financial affairs, and its relations with its customers, employees and service providers (including business plans, customer lists, customer information, account information and consumer
markets). 
 (2) Exceptions. Confidential Information shall not include any information disclosed by a Party that
(i) is already known to the Receiving Party at the time of its disclosure, as evidenced by written records of the Receiving Party, without an obligation of confidentiality at the time of disclosure; (ii) is or becomes publicly known
through no wrongful act of the Receiving Party; (iii) is independently developed by the Receiving Party without use of the Disclosing Party’s Confidential Information as evidenced by written records of the Receiving Party; or (iv) is
obtained by the Receiving Party from any third party without restriction and without breach of any confidentiality obligation by such third party. 
 B. Terms for Handling and Use of Confidential Information. Subject to Article 13.C, for a period of ten (10) years after receipt of any Confidential Information, the Receiving Party shall not disclose Confidential Information
that it obtains from the Disclosing Party to any person or entity except its employees, Affiliates, attorneys, agents and contractors who have a need to know, who have been informed of and have agreed in writing (or, in the case of employees or
attorneys, are otherwise subject to confidentiality obligations consistent with the obligations set forth herein) to abide by the Receiving Party’s obligations under this Article 17. The Receiving Party shall use not less than the same degree
of care to avoid disclosure of such Confidential Information as it uses for its own Confidential Information of like importance; but in no event less than a reasonable degree of care. Confidential Information shall be used by the Receiving Party
only for the purpose of performing its obligations and exercising the rights under this Contract, or as the Disclosing Party otherwise authorizes in writing. 
 C. Legally Required Disclosures. Notwithstanding the foregoing, in the event that the Receiving Party becomes legally compelled (including disclosures necessary or in good faith determined to be reasonably
necessary under the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended), to disclose Confidential Information of the Disclosing Party, including this Contract or other supporting document(s), the Receiving Party
shall, to the extent practicable under the circumstances, provide the Disclosing Party with written notice thereof so that the Disclosing Party may seek a protective order or other appropriate remedy, or to allow the Disclosing Party to request the
redaction of such portions of the Confidential Information as are not required by law to be disclosed. In any such event, the Receiving Party will disclose only such information as is legally required, and will cooperate with the Disclosing Party
(at the Disclosing Party’s expense) to obtain proprietary treatment for any Confidential Information being disclosed.

 D. Return of Confidential
Information. Subject to TerreStar’s rights under Article 13.C, upon the request of the Disclosing Party, the other Party in possession of such Confidential Information shall promptly return such Confidential Information (and any copies,
extracts, and summaries thereof) to the requesting Party, or, with the requesting Party’s written consent, shall promptly destroy such materials (and any copies, extracts, and summaries thereof), except for one (1) copy which may be
retained for legal archive purposes, and shall further provide the requesting Party with written confirmation of same; provided, however, where both Parties have proprietary rights in the same Confidential Information, a Party shall not be required
to return such information to the other Party. 
 E. No License. Except as expressly provided in this Contract, nothing in this
Contract shall be construed as granting the Receiving Party whether by implication, estoppel, or otherwise, any license or any right to use any Confidential Information received from the Disclosing Party, or use any patent, trademark, or copyright
now or hereafter owned or controlled by the Disclosing Party. 
  

	 Article 18.
	 Liquidated Damages 

 A.
Liquidated Damages. In the event that the Key Milestone is not completed [***], then Contractor shall pay liquidated damages, which are not intended to be, and shall not be construed as, a penalty, [***]. Contractor shall pay TerreStar:

 [***]. 
 The total
accumulated liquidated damages payable by Contractor under this Contract for delays in meeting the Key Milestone Date shall not exceed [***], as adjusted by any price impact resulting from changes to the Purchase Price (for these purposes total
Purchase Price will not include the value of any options exercised under this Contract as listed in Exhibit D). 
 B. Exclusions.
Notwithstanding the above provisions, liquidated damages shall not be applicable: (1) for delayed completion of the Key Milestone when such delayed completion is excused by a Force Majeure Event as such is defined in Article 20, or (2) if
such delayed completion is caused by the failure of TerreStar, its agent(s) or its subcontractor(s) (other than Contractor) to act or perform as required under this Contract. Any liquidated damages owed to TerreStar by Contractor shall be due and
payable within thirty (30) days after Contractor’s receipt of TerreStar’s invoice for the same. 
 C. Right to
Terminate. The liquidated damages set forth in this Article 18 shall be TerreStar’s sole remedy and compensation for Contractor delays with respect to the Work. Notwithstanding the previous sentence and use of the term “liquidated
damages” in Article 18.A, nothing in Article 18.A shall be construed to limit TerreStar’s right to terminate this Contract for default pursuant to Article 19 and to recover all applicable damages incurred by TerreStar as a result of any
delay on the part of Contractor to achieve the Key Milestone, assuming the applicable cure period specified in Article 19 has lapsed.

	 Article 19.
	 Termination for Default, Excessive Force Majeure 

 A. TerreStar Right of Termination. 
 (1) Termination for Default. TerreStar
may terminate this Contract for Contractor’s default if: (i) any Milestone test is not successfully completed within sixty (60) days after the scheduled Milestone Date; (ii) Contractor otherwise materially breaches this Contract,
subject to a thirty (30) day cure period; or (iii) Contractor becomes insolvent, makes a general assignment for the benefit of creditors, suffers or permits the appointment of a receiver for its business or assets or files a voluntary
petition in bankruptcy, or is the subject of a petition seeking the reorganization, liquidation or similar relief, where such petition remains undismissed or unstayed for a total of sixty (60) days. 
 (2) Excessive Force Majeure. TerreStar may, upon written notice to Contractor, immediately terminate this Contract, in whole or in
part, if and when: (i) a delay in Contractor’s performance of its obligations hereunder exceeds ninety (90) days due to one or more Force Majeure Events under Article 20.A, or (ii) it becomes reasonably certain that the aggregate
delay due to Force Majeure Events under Article 20.A will exceed ninety (90) days; or (iii) Contractor notifies TerreStar that it is reasonably certain that delay in Contractor’s performance of its obligations hereunder due to Force
Majeure events under Article 20.A will exceed ninety (90) days. Upon the occurrence of any of these events, if Contractor fails to provide TerreStar with a recovery plan reasonably acceptable to TerreStar, TerreStar may provide Contractor
written notice of termination. For the avoidance of doubt, TerreStar may elect not to accept any such recovery plan in its sole discretion if it is likely to cause more than thirty (30) days of additional delay beyond the end of such ninety
(90)-day period. 
 (3) Termination for Invalid Default. If, after termination pursuant to this Article 19, it is
finally determined pursuant to Article 24 or written agreement of TerreStar that Contractor was not in default under Article 19.A(1) or TerreStar had no right to terminate under Article 19.A(2), the rights and obligations of the Parties shall be the
same as if the termination had occurred under Article 21. 
 B. Contractor Right of Termination for Default. Contractor may terminate
this Contract for TerreStar’s default if: (i) TerreStar fails to pay any undisputed amount when due, subject to a thirty (30) day cure period after receipt of notice of Contractor’s intent to terminate; or (ii) TerreStar
otherwise materially breaches this Contract, subject to a thirty (30) day cure period. TerreStar’s issuance of a Stop Work Order shall have the effect of extending the cure period set forth herein during the term of the Stop Work Order.
TerreStar will not be considered in default with respect to any amount that it is disputing in good faith, and TerreStar will have thirty (30) Business Days after the final resolution (by agreement or arbitration) of such Dispute to satisfy any
payment required by such resolution. 
 C. Termination Remedies. 
 (1) TerreStar Termination for Default. If TerreStar terminates the Contract for Contractor’s default, TerreStar may elect
(i) to take and/or retain ownership of any portion of the Deliverable Items supplied up to the date of such termination, and take over the completion of the terminated Work by contract with a third party or otherwise in which case Contractor
shall be liable to TerreStar for any reasonable excess costs for such Work; or (ii) terminate this Contract and pursue its other available remedies, subject to the limitations of liability set forth in this Contract. 
 (2) Contractor Termination for Default. If Contractor terminates the Contract for TerreStar’s default, Contractor shall be
paid as if such termination were for convenience pursuant to Article 21.A, plus any late payment interest based on the Late Payment Interest Rate. Payment of any 

  

 Page 20 
 Use or disclosure of the data contained on this sheet is subject to the restriction on the title page. 

 

 
  
 
amount by any Financing Entity on behalf of TerreStar shall relieve TerreStar from its obligation to make such payment in the corresponding amount. Payment
of the total amounts (termination for convenience amounts plus interest on outstanding invoices) payable by TerreStar pursuant to this Article 19.C shall constitute a total discharge of TerreStar’s liabilities to Contractor for termination
pursuant to Article 19.B. 
 D. Termination Assistance. If this Contract is terminated for any reason, Contractor shall provide up to
twelve (12) months of termination assistance to TerreStar or its designee, at TerreStar’s request and reasonable expense. 
 E.
Disposition of the Work. Upon completion of all payments to Contractor in accordance with Article 19.C(2), TerreStar may require Contractor to transfer title and risk of loss to TerreStar to all Deliverable Items and all Works-in-Process that
are in existence as of the date of termination. In lieu of taking immediate possession of Deliverable Items and Works-in-Process, upon direction of TerreStar, Contractor shall protect and preserve Deliverable Items and Works-in-Process at
TerreStar’s expense and shall facilitate access to and possession by TerreStar to such Deliverable Items and Works-in-Process as and when requested by TerreStar. Alternatively, TerreStar may request Contractor to make a reasonable, good faith
effort to sell such items and to remit any sales proceeds to TerreStar less a deduction for actual costs of disposition reasonably incurred by Contractor. Contractor shall be entitled to retain possession and title to the Deliverable Items and
Works-in-Process in its possession until all payments have been made that are due Contractor under the Contract as a result of the termination by Contractor for TerreStar’s default. If TerreStar fails to pay the undisputed amounts due
Contractor, after an additional ninety (90) day cure period, Contractor may use or dispose of Deliverable Items and Works-in-Process in any manner Contractor may elect. In such case, the fair market value of any Deliverable Items and
Works-in-Process used or disposed of by Contractor shall be set-off against amounts payable by TerreStar under Article 19.C(2), with any remaining balance to be paid to TerreStar. 
 F. Limitation on Right to Terminate. Except as otherwise specified in this Contract, neither Party shall have any right to terminate or suspend this Contract. In the event of a termination
for default by either Party, the terminating Party shall be entitled to seek all other remedies available at law or in equity. 
  

	 Article 20.
	 Force Majeure 

 A.
Definition. Neither Party will be liable for default or delay in the performance of its obligations hereunder, to the extent such default or delay is caused by a “Force Majeure Event,” which occurs when both of the following
circumstances exist: 
 (1) The occurrence of any act of war, domestic and/or international terrorism, civil riots or
rebellions, epidemic, quarantines, embargoes and other similar unusual governmental actions, and extraordinary elements of nature or acts of God delay performance of a Party’s obligations, and 
 (2) Such delay could not have been prevented through the non-performing Party’s reasonable precautions or commercially acceptable
processes, or could not have been reasonably circumvented through the use of substitute services, alternate sources, work-around plans or other means by which the requirements under the Contract would be satisfied. 
 The Parties expressly acknowledge that Force Majeure Events do not include and cannot be caused by labor strikes, lockouts, or other labor disturbances,
or the non-performance of subcontracts or other third parties relied on or otherwise engaged by Contractor, except to the extent such subcontractor’s non-performance is itself the result of a Force Majeure Event.

 B. Equitable Adjustments.
Upon the occurrence of any Force Majeure Event that causes a delay in Contractor’s performance of its obligations hereunder, an equitable adjustment shall be negotiated in the Milestone Schedule and other portions of this Contract affected by
the Force Majeure Event; provided, however, Contractor acknowledges and agrees, there shall be no adjustment to the Purchase Price due to any Force Majeure Event. 
  

	 Article 21.
	 Termination for Convenience 

 A. Termination for Convenience. TerreStar may terminate the Contract in whole for its convenience upon thirty (30) days’ written notice. As TerreStar’s sole liability for termination for convenience, TerreStar shall
pay Contractor for all Milestones successfully completed as of the date of termination, plus all reasonable costs incurred as a result of such termination (including third party termination costs) with respect to terminated work, plus [***] of such
amount; provided that Contractor uses reasonable efforts to mitigate any such costs. 
 B. Termination for [***]. TerreStar may
terminate this Contract without liability, other than payment for any completed Milestones as of the date of termination, upon thirty (30) days’ written notice if [***]. For purposes of this Article 21-B, a [***] shall be defined as [***].

 C. Disposition of Work. Upon payment by TerreStar to Contractor of the amounts due under Article 21, TerreStar may, at its
election, require Contractor to transfer title and risk of loss to TerreStar to all or any part of the Deliverable Items terminated (including any associated Work-in-Process) and Contractor shall, upon direction of TerreStar, protect and preserve
property at TerreStar’s expense in the possession of Contractor or its Subcontractors in which TerreStar has an interest and shall facilitate access to and possession by TerreStar of items comprising all or part of the Work terminated as and
when requested by TerreStar. Alternatively, TerreStar may request Contractor to make a reasonable, good faith effort to sell such items [***]. 
  

	 Article 22.
	 Compliance with U.S. Laws and Directives 

 A. General. 
 (1) Each Party shall, at its expense, perform its respective obligations
hereunder in accordance with all applicable laws, rules, and regulations applicable to such Party’s business (and, with respect to Contractor, applicable to the performance of the Work), and the conditions of all applicable governmental
approvals, permits, or licenses. 
 (2) Without limiting the generality of the foregoing, Contractor will not, directly or
indirectly, take any action that would cause TerreStar to be in violation of U.S. anti-boycott laws under the U.S. Export Administration Act (“EAA”) or as in effect pursuant to the International Emergency Economic Powers Act
(“IEEPA”), the U.S. Internal Revenue Code, the Export Administration Regulations (“EAR”), the Arms Export Control Act (“AECA”) (as implemented by the International Trade in Arms Regulations (“ITAR”)), or any
other regulation thereunder. Neither Party shall, without 
  

 Page 22

prior written authorization from the Department of Commerce, the Department of State or other agency of the U.S. Government having jurisdiction, export or
re-export, directly or indirectly, any U.S. source technical data (as defined in accordance with applicable regulation) acquired from the other Party or any products utilizing any such data, to any country for which at the time of export or
re-export, an export license or other governmental approval is required by an applicable statute or regulation. 
 (3) In its
performance of this Contract, Contractor will not, directly or indirectly, make, offer, or agree to make or offer any loan, gift, donation, or other payment, whether in cash or in kind, for the benefit or at the direction of any candidate,
committee, political party, government or its subdivision, or any individual elected, appointed, or otherwise designated as an employee or officer thereof, for the purpose of influencing any act or decision of such entity or individual or inducing
such entity or individual to do or omit to do anything, in order to obtain or retain business or other benefits except as may be expressly permitted under the Foreign Corrupt Practices Act and the regulations promulgated thereunder. 
 B. Export Licensed Items. Contractor shall be responsible for fulfilling all of its obligations (including without limitation its obligations to
perform the Work and to deliver the Deliverable Items) in full compliance with all applicable export control laws, including without limitation the EAA or as in effect through the IEEPA, (and its implementing regulations), and the AECA (and
its implementing regulations). Contractor shall promptly apply for and use reasonable and diligent efforts to obtain U.S. and non-U.S. Government approvals, permits and licenses necessary for export, re-export, or import of any of the Work and
other technical data and equipment being furnished pursuant to or to be utilized in connection with this Contract. TerreStar agrees to cooperate with Contractor in Contractor’s efforts to obtain any such approvals, permits and licenses,
including providing Contractor with required information in TerreStar’s possession. 
 C. Licenses and Other Approvals for TerreStar
Personnel. Contractor shall timely apply for and, to the extent approved, maintain U.S. Government export licenses, agreements and other approvals that are required for Foreign Person entity representatives of TerreStar (including, but not
limited to, Foreign Person subsidiaries, related entities, or consultants of TerreStar involved with the Work under this Contract) as well as TerreStar’s insurance providers and non-U.S. governmental authorities (as may be required under
applicable law) to have access to Contractor facilities, hardware, software, Deliverable Data, other technical information or technical services in connection with the performance of this Contract. A “Foreign Person” shall be as defined in
the International Traffic in Arms Regulations, 22 C.F.R. §120.16. TerreStar shall provide the reasonable cooperation and support necessary for Contractor to apply for and maintain such required U.S. export licenses, agreements and other
approvals, including providing written notice to Contractor of any foreign persons who require access to Contractor’s goods and technical data (including services) in sufficient time for Contractor to obtain and maintain any required U.S.
Government export licenses, agreements and other approvals. At TerreStar’s request, Contractor shall include TerreStar (and related entities involved with the procurement) as a named Party in any application to the U.S. government for approval
of such export licenses, agreements and other approvals so as to permit TerreStar to be present during any discussion or meetings where TerreStar’s foreign subsidiaries/related entities, insurance providers and/or non-U.S. governmental
authorities may need to receive or discuss export-controlled technical data. Contractor shall provide the Parties to such export licenses and agreements copies of the export licenses and agreements, including any U.S. government provisos related to
same. 
 D. Review of Applications. Contractor shall review with TerreStar any application Contractor makes to any government
department, agency, or entity for any approval, permit, license, or agreement, as may be required for performance of the Work, prior to submission of such application. Contractor

 Use or disclosure of the data contained on this sheet is subject to the restriction on the title page. 

 

 
  
 
shall provide TerreStar five (5) Business Days to review and respond to such application prior to submission to such governmental entity, and Contractor
shall in good faith consider any comments and proposed revisions made by TerreStar for incorporation into such application. 
 E.
Violation of Law. Neither Party shall be responsible in any way for the consequences, direct or indirect, of any violation by the other Party, the other Party’s Subcontractors, or their respective Affiliates of any law, rule or
regulation of any country whatsoever. 
  

	 Article 23.
	 Applicable Law 

 This
Contract shall be interpreted, construed and governed, and the rights of the Parties shall be determined in all respects, according to the laws of the state of New York, without reference to its choice of laws rules. 
  

	 Article 24.
	 Dispute Resolution 

 Any
dispute, claim, or controversy between the Parties arising out of or relating to this Contract (“Dispute”), including any Dispute with respect to the interpretation, performance, termination, or breach of this Contract or any provision
thereof shall be resolved as provided in this Article 24. 
 A. Informal Dispute Resolution. Prior to the initiation of formal Dispute
resolution procedures, the Parties shall first attempt to resolve their Dispute informally, in a timely and cost-effective manner, as follows: 
 (1) The disputing Party shall provide written notice describing the Dispute and recommending corrective actions, and the Parties’ Program Managers shall promptly consult to resolve the Dispute. 
 (2) If the Program Managers are unable to resolve the Dispute within ten (10) days of written notice, either Party may escalate the
Dispute to the executive level, and if the executives are unable to resolve the Dispute either within an additional fifteen (15) days, then the Dispute shall be escalated to the Chief Executive Officer (CEO) of each Party. 
 (3) In the event that the Parties are unable to resolve the Dispute within thirty (30) days of written notice, or if either Party,
in good faith, determines that an amicable resolution does not appear likely, then the Parties may proceed to arbitration. 
 B.
Arbitration. 
 (1) Arbitration. Subject to Article 24.A and Article 24.D, any Dispute arising between the
Parties shall be submitted for settlement by arbitration in accordance with the rules of conciliation and arbitration of the Center for Public Resources, as may be amended from time to time, which are incorporated herein by reference (or if the
Center for Public Resources no longer provides rules or services, then the rules of conciliation and arbitration of the American Arbitration Association). Notwithstanding the foregoing, to the extent any provision of this Article 24.B modifies, adds
to, or is inconsistent with any provision of such rules, the provisions of this Article 24.B shall control. Any such arbitration shall be conducted in Washington, DC by a panel of three (3) arbitrators who shall be selected within forty-five
(45) days after commencement of the arbitration: one selected by each Party and the third selected by the arbitrators chosen by the Parties. Should no agreement be reached within the time specified, the third arbitrator shall be appointed by
the Center for Public Resources. Each arbitrator 

  

 Page 24 
 Use or disclosure of the data contained on this sheet is subject to the restriction on the title page. 

 

 
  
 
appointed by the Parties shall be knowledgeable and experienced in the aerospace and/or satellite telecommunications industries and shall have senior
management and/or legal/judicial experience. 
 (2) Discovery. Discovery shall be permitted as follows: 
 (a) The Parties shall be permitted to take discovery, if and as needed, by deposition upon oral examination, requests for
production of documents and tangible items, and requests for entry upon land for inspection and other purposes, as those discovery methods are described and defined in the Federal Rules of Civil Procedure; provided further that the arbitral tribunal
shall expand or limit discovery in accordance with paragraph (b) below. 
 (b) The scope of permissible
discovery shall generally be as described in Federal Rules of Civil Procedure Rule 26(b)(1), but the Parties shall use their best reasonable efforts to focus and limit their discovery in accordance with the nature of the Dispute and the need for
expedited resolution. The arbitral tribunal may expand or limit the scope of permissible discovery, establish the time period within which discovery responses must be served, and expand or limit the type and number of discovery methods and requests
as it shall determine is appropriate in the circumstances, taking into account the needs of the Parties and the desirability of making discovery expeditious and cost-effective. The arbitral tribunal may issue orders to protect the confidentiality of
proprietary information, trade secrets, and other similar information disclosed in discovery and may order that discovery not be had or that discovery may be had only on specific terms and conditions. 
 (3) Language. Proceedings and documents provided and generated in connection with any arbitration hereunder shall be in the
English language. 
 (4) Costs and Expenses. Each Party shall bear its own costs and expenses (including the costs and
expenses of the arbitrator it selected) and one-half of the costs and expenses of the third arbitrator, unless otherwise determined in the arbitral award. 
 (5) Expedited Arbitration. Time is of the essence in the initiation and completion of the arbitration. The arbitral hearing shall be commenced and conducted expeditiously. Unless the arbitral tribunal orders
otherwise, the Dispute should be submitted to the tribunal for decision within six (6) months after the commencement of the arbitration, and the final award shall be rendered within one (1) month thereafter. The Parties and the tribunal
shall use their best reasonable efforts to comply with this schedule, and the tribunal may impose any remedy it deems just for any Party’s effort to unnecessarily delay, complicate, or hinder the proceedings. 
 (6) Final and Binding Decision. Any arbitration hereunder shall be governed by the United States Arbitration Act, 9 U.S.C.
§§ 1 et seq. The arbitrators’ decision shall be final and binding on the Parties and enforceable in any court of competent jurisdiction. 
 C. Arbitration Award. The arbitral tribunal’s award may grant any remedy or relief the tribunal deems within the scope of this Contract, but may not make any award in any amount or on any theory of
liability except as otherwise allowed or provided in this Contract. Notwithstanding the foregoing, the tribunal shall have no power or authority to amend or disregard any provision of this Article 24.C or any other provision of this Contract; in
particular, but without limiting the generality of the foregoing, the tribunal shall not have the power or authority to exclude the right of a Party to terminate this Contract when a Party would otherwise have such right. Any monetary award made by
the arbitrators shall be subject to the limitation of liability set forth in Article 34.

 D. Litigation.
Notwithstanding the provisions of Article 24.A and Article 24.B above, either Party may resort to court action for injunctive relief at any time if the Dispute resolution process would permit or cause irreparable injury to such Party or any third
party claiming against such Party, due to delay arising out of the Dispute resolution process. 
 E. Continued Performance. Unless the
Dispute involves a termination of the Contract under Article 19 or Article 21: (i) pending final resolution of any Dispute, each Party shall, unless directed otherwise by the other Party in writing, continue to perform all its obligations under
this Contract to the extent undisputed and practical to do so, including the obligation to take all steps necessary during the pendency of the Dispute to ensure the Work will be performed within the time stipulated or within such extended time as
may be allowed under this Contract; and (ii) failure to pay disputed amounts shall not excuse failure to so perform the Work. 
  

	 Article 25.
	 Changes 

 A. Unique
Requirements. The Parties acknowledge and agree that TerreStar has unique requirements, and Contractor has solutions regarding the S-BSS to be provided by Contractor. Accordingly, to the extent not already provided for in the Contract, the
Parties agree to negotiate in good faith in accordance with the applicable change control procedures to provide the maximum flexibility in meeting TerreStar’s S-BSS requirements. 
 B. Changes Requested by TerreStar. 
 (1) Scope.
TerreStar may, in writing, request a change in the Work within the general scope of this Contract to: 
 (a)
Order work in addition to the Work provided for herein; or 
 (b) Modify the whole or any part of the Work
provided for herein; or 
 (c) Direct the stoppage of Work, in whole or in part, by issuance of one or more
“stop work” orders (each a “Stop Work Order”), for up to an aggregate of eighteen (18) months; 
 (2) Response to Change Request. Contractor shall respond in writing to any such requested change within twenty (20) days after receipt of such requested change, unless the change request is designated as “urgent” by
TerreStar, in which case Contractor shall use commercially reasonable efforts to respond within seven (7) days after its receipt of such change request. 
 (3) Equitable Adjustment to Schedule/Pricing. If such change request causes an increase or decrease in the cost or the time required for completion of the Work to be provided, or otherwise
affects any other provision of this Contract, such response shall provide a non-binding preliminary estimate of the impact of the change request on the Purchase Price (including costs associated with processing of the change request), Milestone
Schedule and other provisions of this Contract. Contractor shall use commercially reasonable efforts to propose and perform the changed Work in a manner that minimizes TerreStar’s costs and any Milestone Schedule delays. Any proposed increase
to the price or extension of the Milestone Schedule shall be equitable and proposed in good faith and shall not exceed the expected actual cost to be incurred by Contractor, [***], and the actual time required by Contractor to implement the change.
Changes required by the obsolescence of components of the S-BSS or any other Deliverable Item shall be made by Contractor at Contractor’s cost and expense. If TerreStar desires to proceed with the change after receipt of Contractor’s
preliminary estimate, TerreStar and Contractor shall cooperate and negotiate in good faith and agree in a timely manner to equitable 

  

 Page 26 
 Use or disclosure of the data contained on this sheet is subject to the restriction on the title page. 

 

 
  
 
adjustments in the Purchase Price, Milestone Schedule, Milestone Dates and other affected provisions of this Contract, and this Contract shall be amended in
writing accordingly in accordance with Article 35.D. 
 (4) Change Order Dispute. In the event the Parties fail to
agree on an adjustment (upward or downward) to the Purchase Price, Milestone Schedule or other affected provisions of this Contract with respect to a requested change, then TerreStar may direct Contractor to proceed with the requested change, in
which case, Contractor shall proceed with the change as so directed. The Parties shall continue to negotiate the adjustments to the Contract, and pending completion of such negotiations or dispute resolution, and as a condition for Contractor being
obligated to proceed with the directed change, the Parties in good faith shall agree upon and establish a reasonable payment schedule for the portion of the equitable adjustment to which the Parties agree, to compensate Contractor for the Work
performed pursuant to the directed change, which payment schedule shall be adjusted as part of the negotiated settlement for the directed change. If the Parties are unable to agree upon an equitable adjustment resulting from a change order, either
Party may submit the matter for determination under Article 24. 
 (5) Stop Work Direction. In the case of a Stop Work
Order, Contractor shall stop Work immediately to the extent specified by TerreStar. 
 (6) Mitigation of Stop Work
Costs. Contractor shall use commercially reasonable efforts to require its Subcontractors to agree to a “Stop Work” provision that minimizes Contractor’s costs and is consistent with the terms of this Article 25.B(6). In the event
of a Stop Work Order, Contractor shall use commercially reasonable efforts to mitigate costs and shall cooperate in good faith with TerreStar in connection with actions taken by Contractor with respect to its Subcontractors. 
 (7) Tolling of Payments. Notwithstanding the foregoing, in the event TerreStar issues a Stop Work Order, all payments due
Contractor (except for payments due and payable prior to the date of the Stop Work Order) shall be tolled and shall not accrue for the duration of the Stop Work Order (up to the cumulative maximum period provided in Article 25.B(1)(c) above). If

Insured. TerreStar and each Financing Entity shall be named as an additional insured under Contractor’s third-party liability coverages, provided that, with respect to each Financing Entity, such Financing Entity has an insurable interest

against TerreStar and TerreStar’s Affiliates and their respective associates.
