 Exhibit 10.3 

SECURITY CONTROL AGREEMENT 

This agreement (the “Agreement”) is made this 26th day of January, 2016 (“Effective Date”), by and among
MacDonald, Dettwiler and Associates Ltd., a publicly traded British Columbia corporation headquartered in the United States (the “Shareholder”), SSL MDA Holdings, Inc., a Delaware corporation (the “Company”) and the
U.S. Department of Defense (i.e., DoD), all of the above collectively the “Parties.” 
 RECITALS 

WHEREAS, the Company is duly organized and existing under the laws of the State of Delaware and has an authorized capital of 100,000
shares, all of which are common voting shares, par value $0.01 per share, of which 62,181 shares are issued and outstanding (the “Shares”); and 

WHEREAS, the Shareholder owns 100 percent of the Shares; and 

WHEREAS, the Shareholder has no parent or controlling shareholders; and 

WHEREAS, while it is normal for DSS to use a Security Control Agreement in cases of minority foreign ownership, the Shareholder is
structured as a holding company that serves as the interface with the group’s public shareholders, many of whom may be U.S. citizens; and 

WHEREAS, the Company is the Shareholder’s only direct operating subsidiary and is the group’s highest-tier decision-making
entity; and 
 WHEREAS, the Company owns and controls several operational U.S. subsidiaries, some of which require or will require a
DoD facility security clearance; and 
 WHEREAS, the Company owns the general partner of a Delaware limited partnership
(“USLP”) that holds all the voting interests of various non-U.S. operating subsidiaries; and 

WHEREAS, the Shareholder holds the non-voting economic interests of USLP and its non-U.S. operating subsidiaries; and 
 WHEREAS, the National Industrial Security Program Operating
Manual (i.e., NISPOM) requires mitigation of the risks of foreign ownership, control or influence (i.e., FOCI) in order for a company to maintain eligibility for a facility security clearance (as defined in the NISPOM); and 

WHEREAS, the Company’s business consists of the provision of communications and surveillance and intelligence solutions to various
agencies of the U.S. Government, including, without limitation, the DoD, which requires the Company and one or more of its Controlled Entities (as defined in Article V herein) to have facility security clearances; and the rendering of industrial
security services by the Defense Security Service (i.e., DSS) as may be applicable for DoD and other U.S. government agencies pursuant to Section 1-103 of the NISPOM; and 

  
 1 








 WHEREAS, the DoD will not grant or continue the facility security clearance(s) of the
Company and its Controlled Entities without, at a minimum and without limitation, the Parties’ execution and compliance with the provisions of this Agreement, the purpose of which is to reasonably and effectively deny the Affiliates, as defined
below, unauthorized access to classified information (as that phrase is defined in the NISPOM) and other information that is the subject of U.S. export control laws and regulations (“Export Controlled Information”) and influence
over the Company’s business or management in a manner that could result in the compromise of classified information or could adversely affect the performance of contracts pursuant to which access to classified information may be required. As
used herein, the term “Affiliates” means (a) the Shareholder and its non-US shareholders of greater than 10% and (b) any entity that now or in the future may directly or indirectly
control the Shareholder, be directly or indirectly controlled by the Shareholder, or be directly or indirectly under common control with the Shareholder. Notwithstanding the foregoing, an entity that operates under a DSS FOCI mitigation agreement,
including the Company and its Controlled Entities, will not be considered an Affiliate for purposes of this Agreement so long as the entity’s FOCI mitigation agreement remains in effect. In case of doubt, mitigation imposed by the Committee on
Foreign Investment in the United States is not a FOCI mitigation agreement as that term is used herein; and 
 WHEREAS, DSS has
determined that the provisions of this Agreement are necessary to enable the United States to protect itself against the unauthorized disclosure of information relating to the national security; and 

WHEREAS, the Company has agreed to establish a formal organizational structure, policies and procedures to ensure the protection of
classified information and Export Controlled Information entrusted to it and to place the responsibility therefor with a committee of its Board of Directors (the “Company Board”) to be known as the Government Security Committee, all
as hereinafter provided; and 
 WHEREAS, the Parties agree that control of the Company should be vested in the Company Board;
and 
 WHEREAS, the Parties have agreed that management control of the defense and technology security affairs and classified
contracts of the Company should be vested in resident citizens of the United States who have DoD personnel security clearances (as defined in the NISPOM); and 

WHEREAS, each Affiliate that is a Party to this Agreement, by its authorized representative, hereby affirms that: (a) it will not
seek access to or accept classified information or Export Controlled Information entrusted to the Company, except as permissible under the NISPOM and applicable U.S. Government laws and regulations; (b) it will not attempt to control or
adversely influence the Company’s performance of classified contracts and participation in classified programs; and (c) except as expressly authorized by this Agreement, its involvement (individually and collectively) in the business
affairs of the Company shall be limited to participation in the deliberations and decisions of the Company Board and authorized committees thereof; and 

  
 2 








 WHEREAS, in order to meet DoD’s national security objectives in the matter of the
Company’s facility security clearance(s) and to further the Company’s business objectives, the Parties intend to be bound by the provisions of this Agreement. 

NOW THEREFORE, it is expressly agreed by and among the Parties that this Agreement is hereby created and established subject to the
following terms and conditions to which all of the Parties expressly assent and agree: 
 ORGANIZATION 

ARTICLE I - Management of the Company’s Business 

1.01. Composition of the Company’s Board of Directors. The composition of the Company Board will be determined by the Shareholder
in accordance with applicable law and this Agreement. During the term of this Agreement, the Company Board: 
 a. must include a minimum of
one person meeting the qualifications set forth in NISPOM § 2-305 (each an “Outside Director”); 

b. may include one or more cleared officers of the Company (each an “Officer Director”); 

c. must include a number of Outside Directors that equals or exceeds the number of Inside Directors; provided that, for purposes of this
Agreement, the term “Inside Director” means a member of the Company Board who is not an Officer Director or an Outside Director, as those terms are defined herein; provided that any director who is also a significant shareholder,
director, officer, employee, agent or representative of any Affiliate, as that term is defined herein, is deemed to be an Inside Director, except where DSS has given its consent in advance and in writing. For example, the Company’s Chief
Executive Officer and Outside Directors, each as of the Effective Date, may be permitted by DSS to hold interlocking positions at the Shareholder; 

d. may consist of a combination of Outside Directors, Inside Directors, and Officer Directors; 

e. must not have an Inside Director as the Company’s Chairman of the Board, except as specifically provided herein; and 

f. must be composed of persons serving on the Company Board who are possessed with, and capable of, exercising all of the rights, powers,
privileges, immunities and duties conferred or imposed upon such persons by applicable statutes and regulations, and by the Company’s charter and governing documents; provided that, each Outside Director and each Officer Director perform his or
her or duties, including fiduciary duties, in accordance with his or her Best Efforts. “Best Efforts” means performance of duties reasonably and in good faith, in the manner believed to be in the best interests of the Company, but
consistent with the national security concerns of the United States, and with such care, including reasonable inquiry, as an ordinarily prudent person in a like position would use under similar circumstances. 

  
 3 








 1.02. Actions by the Company Board. 

a. No action may be taken by the Company Board or any committee thereof in the absence of a quorum, as defined below. 

b. A majority of the Company Board, including at least one Outside Director, shall be necessary to constitute a quorum. Where the Company Board
is composed, in its entirety, of an even number of directors and a quorum consists of all the directors, then the Chairperson of the Board shall have the authority to cast the deciding vote in case of a tie among the directors. With respect to the
Government Security Committee (see Section 7.01 below), a majority of the committee shall be necessary to constitute a quorum. With respect to all other standing committees of the Company Board, including the Compensation Committee (see
Section 8.01 below), a majority of each such committee, including at least one Outside Director shall be necessary to constitute a quorum. 

ARTICLE II - Limitations on the Company Board and Disclosure of Investor Protections 

2.01. Investor Protections. An “Investor Protection” means a legally enforceable right to: 

a. prevent the merger, consolidation, reorganization, or dissolution of the Company; the liquidation, sale or pledge of all or substantially
all of the assets of the Company; the acquisition by the Company of a company, business, or other legal entity; the entrance by the Company into financing arrangements or indebtedness in excess of $5,000,000 other than in the Normal Course of
Business (as that term is defined in the Company’s Signing Authority Matrix approved by the Shareholder); or a voluntary filing for bankruptcy or liquidation or any sale of any business of the Company or any Controlled Entity or any assets
having a value in excess of $5,000,000, other than in the Normal Course of Business; 
 b. purchase additional shares in the Company to
prevent the dilution of an investor’s pro rata interest in the Company in the event that the Company issues new shares; 
 c. prevent
the change of existing legal rights or preferences of the shares, as provided in the Company’s charter documents; 
 d. prevent the
amendment of the Company’s charter documents with respect to the matters described in (a) through (c) of this paragraph; 
 e.
approve or disapprove the Company’s execution of unclassified contracts valued in excess of $25,000,000 other than in the Normal Course of Business; 

f. approve or disapprove capital expenditures by the Company in excess of $5,000,000 other than in the Normal Course of Business; 

g. cause the Company to adopt the risk-management policies of the Shareholder with respect to regulatory and legal compliance, contract
overruns (for unclassified contracts only), and related matters; 

  
 4 








 h. cause the Company to adopt the financial reporting standards and policies of the Shareholder;

 i. cause the Company to adopt the corporate strategies (not involving classified information or contracts) of the Company and the
Controlled Entities involving capital and financial structuring; and 
 j. hold meetings among Shareholder personnel and Company or
Controlled Entities personnel with respect to administrative, financial, and operational matters, including any matters with respect to approved budgets, including remediation actions, related to commercial and
non-U.S. classified and export-controlled activities and contracts (such meetings shall not be subject to the request and approval procedures of Article XI of the Agreement, but records of such meetings shall
be maintained pursuant to Section 11.09 of the Agreement). 
 2.02. Company Board Actions, Shareholder Consent. Nothing in this
Agreement authorizes the Company Board to initiate any action to terminate this Agreement, except as provided in Section 16.01, or to take any action inconsistent with an Investor Protection without the prior written consent of the Shareholder.

 2.03. Extraordinary Shareholder Rights Superseded. Extraordinary shareholder rights in the Company, if any, of the Shareholder
other than one or more Investor Protections are superseded by this Agreement for the duration of this Agreement without prior written consent of DSS FOCI Operations Division and the Government Security Committee voting unanimously. Investor
Protections are not created by this Agreement; however, if any Investor Protection exists, it is not superseded by this Agreement. 
 ARTICLE III
- Qualification, Appointment, and Removal of Directors; Board Vacancies 
 3.01. Company Board Requirements. During the period
that this Agreement is in force, the Company Board shall be composed as provided in Section 1.01 above, and the directors shall meet the following additional requirements: 

a. each Officer Director and Outside Director shall be a resident citizen of the United States and have or be eligible to have DoD personnel
security clearances at the level of the Company’s facility security clearance; 
 b. each Outside Director shall have been approved by
DSS as satisfying the appropriate DoD personnel security requirements and the applicable provisions of this Agreement; 
 c. at least two
Outside Directors shall be designated to serve on the Shareholder board of directors, and each other Outside Director shall be granted by the Shareholder the right to attend any meetings of the Shareholder board of directors; and 

  
 5 








 d. each Inside Director, in his or her capacity as director of the Company, shall not have a DoD
personnel security clearance in connection with the Company’s facility security clearance, regardless of his or her citizenship, and he or she shall be formally excluded from access to classified information by resolution of the Company Board.

 3.02. Removal of Directors. The Shareholder may remove any director for any reason permitted by the provisions of applicable state
law or the Company’s Certificate of Incorporation or bylaws, provided that: 
 a. the removal of an Outside Director shall not become
effective until: (i) that director, the Company, and DSS have been notified; (ii) DSS has provided written notice stating no objection; and (iii) a successor who is qualified to become an Outside Director within the terms of this
Agreement has been nominated by the Company and approved by DSS; 
 b. the Company, through its Facility Security Officer (i.e., FSO), shall
provide written notice to DSS of the Shareholder’s intention to remove an Outside Director at least twenty (20) days prior to the proposed removal date, except as noted in Section 3.02.c. below; and 

c. notwithstanding the foregoing, if immediate removal of an Outside Director is deemed necessary to prevent the actual or possible violation
of any statute or regulation, or actual or possible damage to the Company, the Outside Director may be removed at once, provided that DSS shall be notified in writing prior to or concurrently with such removal. 

3.03. Vacancy on the Company Board. In the event of any vacancy on the Company Board, however occurring, the Company shall give prompt
notice of such vacancy to the Shareholder and DSS, through its FSO, and such vacancy shall be filled promptly by the Shareholder. In a case of vacancy of an Outside Director position, such vacancy shall not exist for a period of more than ninety
(90) days after that Outside Director’s resignation, death, disability or removal unless DSS is notified of the delay. 
 3.04.
Departing Director. Except as provided by this section, the obligation of a director to abide by and enforce this Agreement shall terminate when the director leaves office, but nothing herein shall relieve the departing director of any
responsibility that the director may have, pursuant to the laws and regulations of the United States, not to disclose classified information or Export Controlled Information obtained during the course of the director’s service on the Company
Board, and such responsibility shall not terminate by virtue of the director leaving office. The Company’s FSO shall advise the departing director of such responsibility when the director leaves office, but the failure of the FSO to so advise
the director shall not relieve the director of such responsibility. 
 ARTICLE IV - Indemnification of Outside Directors 

4.01. Obligations of Outside Directors. Each Outside Director, in his or her capacity as a director of the Company, shall vote and act
on all matters before the Company Board in accordance with his or her Best Efforts. 

  
 6 








 4.02. Indemnification of Outside Directors. The Company shall indemnify, and the Company
and the Shareholder shall hold harmless, each Outside Director from any and all claims arising from, or in any way connected to, his or her performance as a director of the Company under this Agreement, except for his or her own individual gross
negligence or willful misconduct. To the extent permitted by law, the Company shall advance fees and costs incurred in connection with the defense of any such claim. The Company may purchase insurance to cover this indemnification. 

ARTICLE V- Restrictions Binding on the Company’s Controlled Entities 

5.01. Controlled Entities. The Parties agree that the provisions of this Agreement shall apply to, and shall be binding upon, all
present and future Controlled Entities. For purposes of this Agreement, the term “Controlled Entities” shall mean those subsidiary corporations (as defined in the NISPOM) and other entities in which the Company owns a controlling
interest, either directly or indirectly through the Company’s ownership interest in intermediate entities, as determined by DSS. The Company hereby agrees to undertake any and all measures and provide such authorizations as may be necessary to
effectuate this requirement. The sale of, or termination of the Company’s control over, any Controlled Entity shall terminate the applicability to it of the provisions of this Agreement. 

5.02. DSS Notification of Newly Formed and Acquired Controlled Entities. If the Company proposes to form a new Controlled Entity, or to
acquire a Controlled Entity, it shall give written notice to DSS and shall advise DSS immediately upon consummation of such formation or acquisition. 

5.03. Applicability of Agreement to Newly Formed and Acquired Controlled Entities. It shall be a condition of each such formation or
acquisition, discussed in Section 5.02 above, that all security measures applicable to the Company as required by this Agreement, including without limitation the security measures described in Articles VII and XI, shall apply to each
Controlled Entity immediately upon consummation of such formation or acquisition, and that the Company and the Controlled Entity shall execute a document agreeing that such company shall be bound thereby. A copy of said executed document shall be
forwarded to DSS. 
 5.04. Currently Controlled Entities. A document such as described in Section 5.03 above shall also be
executed and submitted to DSS within forty-five (45) days of the execution of this Agreement for each applicable Controlled Entity. 

5.05. Third-Party Beneficiaries. Compliance with this Article V shall not confer the benefits of this Agreement on the affected
companies. Those companies shall not be entitled to receive a facility security clearance, nor shall they be entitled to access classified information, to perform on classified contracts or to participate in classified programs pursuant to this
Agreement, solely by virtue of their legal relationship with the Company or by their execution of the documents referred to in Sections 5.03 and 5.04 above.

ARTICLE VI - Operation of this Agreement 

6.01. Policies, Practices and Resolutions. The Company shall at all times maintain policies and practices to ensure (A) the
safeguarding of classified information and Export Controlled Information entrusted to it, (B) the performance of its classified contracts and its participation in classified programs for the U.S. Government in accordance with the DoD Security
Agreement (DD Form 441 or its successor form), and (C) compliance with this Agreement, appropriate contract provisions regarding security, U.S. export control laws and regulations, and the policies duly authorized under the NISPOM. Each Outside
Director shall execute for delivery to DSS, upon accepting his or her appointment and thereafter at each annual meeting between the GSC and DSS, a certificate in substantially the form attached hereto as Attachment C. 

a. The following additional protections shall be established in the charter documents and/or resolutions of the Company’s Board, and
acknowledged by the Shareholder’s Board of Directors, in each case as provided in Sections 6.01.a.1 and 6.01.a.2 below, and shall control the actions of the Parties during the term of this Agreement: 

1. Pursuant to a resolution of the Company Board in substantially the form attached hereto as Attachment A, which shall not be repealed or
amended without prior approval of DSS, the Company shall exclude the Affiliates and all of their directors, officers, employees, agents and other representatives, from access to classified information and Export Controlled Information entrusted to
the Company. The above exclusion shall not, however, preclude the exchange of classified information or Export Controlled Information between the Company and an Affiliate when such exchange is permissible under the NISPOM and applicable U.S. laws
and regulations. 
 2. Pursuant to resolutions of the Shareholder’s Board of Directors substantially in the form attached hereto as
Attachment B, which shall not be repealed or amended without prior approval of DSS, the Shareholder shall formally acknowledge and approve the Company’s resolution referred to in Section 6.01.a.1. above, and shall additionally resolve: 

(i) to exclude all Affiliates, including itself, and all directors, officers, employees, agents and other representatives of any of them from
access to classified information and Export Controlled Information entrusted to the Company, except as expressly permitted pursuant to Section 6.01.a.1. above; 

(ii) to grant the Company the independence to safeguard classified information and Export Controlled Information entrusted to it; and 

(iii) to refrain from taking any action to control or influence the performance of the Company’s classified contracts or the
Company’s participation in classified programs. 

  
 8 








 ARTICLE VII - Government Security Committee 

7.01. GSC Established. There must be established a permanent committee of the Company Board, to be known as the “Government
Security Committee” (i.e., GSC), consisting of all Outside Directors and Officer Directors, if any. The GSC must cause the Company to maintain policies and procedures to safeguard classified information and Export Controlled Information
entrusted to the Company and to ensure that the Company complies with the DoD Security Agreement (DD Form 441 or its successor form), this Agreement, appropriate contract provisions regarding security, U.S. export control laws and regulations, and
the NISPOM. The provisions of this Article VII must be set forth in the relevant place within the Company’s charter documents. 
 7.02.
GSC Chairperson. The GSC must designate an Outside Director to serve as Chairperson of the GSC. 
 7.03. GSC Secretary. The
Chairperson of the GSC must designate a member to be the Secretary of the GSC. The Secretary’s responsibilities shall include ensuring that all records, journals and minutes of GSC meetings and other documents sent to or received by the GSC are
prepared and retained for inspection by DSS. 
 7.04. GSC Performance Standards. The members of the GSC must exercise their Best
Efforts to ensure the implementation within the Company of all procedures, organizational matters and other aspects pertaining to the security and safeguarding of classified information and Export Controlled Information called for in this Agreement,
including the exercise of appropriate oversight and monitoring of the Company’s operations to ensure that the protective measures contained in this Agreement are effectively maintained and implemented. 

7.05. Facility Security Officer. An FSO must be appointed by the Company as the principal advisor to the GSC concerning the safeguarding
of classified information. The FSO’s responsibilities must also include the operational oversight of the Company’s compliance with the requirements of the NISPOM. The Chairperson of the GSC must provide advice and consent in selecting and
retaining the FSO. The Company must therefore provide advanced notice to the Chairperson of the GSC regarding its intention to remove the FSO from his or her position and is not permitted to remove the FSO without the advice and consent of the
Chairperson of the GSC. 
 7.06. Technology Control Officer. With the advice and consent of the Chairperson of the GSC, the Company
must appoint a “Technology Control Officer” (i.e., TCO). The TCO must report to the GSC as its principal advisor concerning the protection of Export Controlled Information. The TCO must establish and administer all Company
procedures for the prevention of unauthorized disclosure or export of Export Controlled Information and compliance with the requirements of U.S. export control laws and regulations. 

  
 9 








 7.07. Compliance Program. In addition to the general security procedures referenced in
Section 7.01, the GSC must cause the Company to implement a detailed FOCI compliance program to include the following: 
 a.
Technology Control Plan. The GSC must cause the Company to develop and implement a “Technology Control Plan” (i.e., TCP), as defined in the NISPOM. The GSC may establish the Company’s policy regarding the TCP. The TCP
must prescribe measures to prevent the unauthorized disclosure or export of Export Controlled Information consistent with applicable U.S. laws and regulations. 

b. Electronic Communications Plan. The GSC must cause the Company to take necessary action, and maintain oversight to provide assurance
to itself and DSS that electronic communications between the Company and its Controlled Entities, on the one hand, and the Affiliates, on the other hand, do not disclose classified information or Export Controlled Information without proper
authorization. Accordingly, the GSC must establish written policies and procedures known as an “Electronic Communications Plan” (i.e., ECP). The ECP must also provide assurance that electronic communications are not used by any of
the Affiliates to exert influence or control over the Company’s business or management in a manner that could adversely affect the performance of classified contracts. As used in this Agreement, the term “electronic
communications” is defined broadly to mean any transfer of information, data, signs, signals, writing, images, sounds, or intelligence of any nature including that transmitted in whole or in part by wire, radio cable, or other like
connection, or by electromagnetic, photo-electronic, photo-optical, electronic, mechanical or other device or system. Any such transfer may be oral, written or electronic and includes any intercepted or recorded content however acquired and whether
or not intended for the recipient. Electronic communications shall also include the temporary, intermediate storage incidental to the electronic transmission thereof as well as any storage for purposes of backup protection. For clarification, common
devices used to transfer electronic communications, as used in this Agreement, include without limitation: telephone (including teleconferences), facsimile, video (including videoconferences), internet (including Voice over Internet Protocol,
instant messaging and any other web-based means), and electronic mail. The ECP must include a detailed network configuration diagram that clearly shows all communications networks and facilities used by the
Company for the transmission of electronic communications, as defined herein, including without limitation, any computer equipment used for the electronic storage of such communications, and must delineate which networks will be shared and which
will be protected from access by any unauthorized person, including without limitation, each of the Affiliates. The ECP must also include network descriptions addressing firewalls, physical and logical access controls, remote administration,
monitoring, maintenance, retention, and the electrical and physical separation of systems and servers, as appropriate. 
 c. Affiliated
Operations Plan. The GSC must establish and maintain oversight over the Company’s Affiliated Operations Plan (i.e., AOP), a template of which is available from DSS. The AOP is the Company’s consolidated policies and procedures, signed
by the Chairperson of the GSC, regarding the control of Affiliated Operations among the Company (or any of its Controlled Entities) and any of the Affiliates. The purpose of the AOP is to provide the GSC with an understanding of how the Company is
organized, structured and financed so as to be capable of operating as a viable business entity independent from the Affiliates. The Company is not permitted to engage in Affiliated Operations that are not duly authorized and must follow the terms
of the approved AOP. As used herein, “Affiliated Operations” means cooperative endeavors, regardless of whether such endeavors are administrative, operational or commercial, performed directly or through third-party service
providers, all of which are more specifically categorized and described below. In the Company’s Annual Compliance Report 

  
 10 








 
described in Article 9, the GSC must certify the effective execution the terms of the Affiliated Operations as described in the AOP and that the Affiliated Operations do not circumvent the
requirements of this Agreement. The Company, through its FSO, must update the AOP as necessary and submit the same to DSS for review. Specific approval responsibilities and requirements are as follows: 

1. Shared Employees. Shared employees are a category of Affiliated Operations where (i) Affiliate personnel are assigned to work,
in whole or in part, in support or on behalf of the Company or any Controlled Entity, whether or not performance is governed by the terms of a relevant agreement among the affiliated companies or (ii) persons employed by the Company (or any
Controlled Entity) are assigned to work, in whole or in part, in support or on behalf of any Affiliate, whether or not performance is governed by the terms of relevant agreement among the affiliated companies. Shared employees are not permitted
prior to DSS approval of a corresponding AOP. 
 2. Shared Third-Party Services. Shared third-party services are a category of
Affiliated Operations where, to the knowledge of the Company, a service (e.g., a professional service such as accounting, legal, tax, information technology, or business consulting) will be provided by a third party service provider to both the
Company (or any of its Controlled Entities) and any Affiliate. Subject to DSS review, approval by a majority of the GSC is sufficient to authorize a third party shared service if it does not involve a conflict of interest and will not adversely
affect the Company’s ability to comply with this Agreement. In addition, the GSC must include a description of the third party shared services approved in this manner in the Company’s AOP within ten (10) days of its decision and
provide the same to DSS. DSS, in its sole discretion, may require the GSC to rescind any approval made under this paragraph if DSS determines that a conflict of interest or adverse effect on the Company’s ability to comply with the security
measures required by this Agreement is reasonably likely and insufficiently mitigated. DSS review under this paragraph will normally consider separate engagement letters, separate projects and the like as mitigating factors. 

3. Commercial Arrangements. “Commercial Arrangements” are a category of Affiliated Operations that includes
commercially arm’s length transactions in the form of contracts and subcontracts, joint research, development, marketing or other type of teaming arrangement between the Company (or any Controlled Entity) and any Affiliate. Prior to any
Commercial Arrangements, the GSC must approve the Commercial Arrangements by majority vote. In addition, the GSC must include a description of the Commercial Arrangements approved in this manner in the Company’s AOP within ten (10) days of
its decision and provide the same to DSS. 
 4. Other Shared Services and Products. The term Affiliated Operations also includes
products or services provided other than in a Commercial Arrangement (i.e., below arm’s length cost) by an Affiliate to the Company (or any of its Controlled Entities) or by the Company (or any of its Controlled Entities) to any Affiliate.
Other shared services and products are not permitted prior to DSS approval of a corresponding AOP. 

  
 11 








 5. Affiliate Technology. Anytime the Company (or any of its Controlled Entities) will use
technology products or services of an Affiliate in performance on contracts requiring access to classified information, the Company’s management shall notify each applicable Government Contracting Activity (i.e., GCA), as that term is defined
in the NISPOM, regarding the applicable technology products or services provided under the contract. The Company must include this notification as an addendum to the AOP. In the event that a GCA elects to not receive such notification, the Company
must include the GCA’s written statement opting out of notification as an addendum to the AOP. 
 d. Facility Location Plan. The
Company must not permit its facilities and personnel to be collocated with the facilities and personnel of the Affiliates. The Company must seek prior written DSS approval of a Facility Location Plan, which means a description of the location of
each of the facilities of the Company and closely located Affiliate facilities. Where DSS determines appropriate, DSS shall request and the Company shall provide maps and floor plans showing where employees occupy space in each facility. DSS
approval of the Company’s plan shall not be determined solely on the physical proximity of the facilities. DSS may approve a plan involving facilities that are closely located. It shall be a reasonable expectation of the Parties that any DSS
review under this paragraph will be primarily concerned with physical proximity that, in DSS’s sole determination, is likely to degrade the Company’s ability to comply with the security measures required by this Agreement. 

7.08. Closed Sessions. Discussions of classified information and Export Controlled Information by the GSC must be held in closed
sessions and in accordance with applicable security requirements related to the classification level of the information discussed. Minutes of such meetings shall be recorded and safeguarded in accordance with applicable information security
requirements and made available only to such authorized individuals as are so designated by the GSC. 
 7.09. DSS Briefings. Upon
taking office, the GSC members, the FSO and the TCO must be available for briefing by a DSS representative on their responsibilities under the NISPOM, U.S. export control laws and regulations and this Agreement. 

7.10. GSC, FSO and TCO Obligations and Certification. 

a. Obligations. Each member of the GSC, the FSO and the TCO must exercise his or her Best Efforts to ensure that all provisions of this
Agreement are carried out; that the Company’s directors, officers, employees, representatives and agents comply with the provisions of this Agreement; and that DSS is advised of any known violation of, or known attempt to violate, any provision
of this Agreement, contract provisions regarding security, U.S. export control laws and regulations, and the NISPOM. 
 b.
Certifications. Each member of the GSC must execute for delivery to DSS, upon accepting his or her appointment and thereafter at each annual meeting between the GSC and DSS, as established by this Agreement, a certificate in substantially the
form attached hereto as Attachment D acknowledging: (1) the protective security measures taken by the Company to implement this Agreement; and (2) that the U.S. Government has placed its reliance on him or her as a U.S. citizen and as the
holder of a personnel security clearance to exercise his or her Best Efforts to ensure compliance with the terms of this Agreement and the NISPOM. Each member of the GSC must further acknowledge his or her agreement to be bound by and to accept his
or her responsibilities under this Agreement. 

  
 12 








 7.11. Cleared Officer Obligations and Certification. Pursuant to NISPOM § 2-104, DSS may require persons occupying official positions at the Company to be granted personnel security clearances or be excluded from classified access. The GSC shall require that each such officer of the
Company with a personnel security clearance exercise his or her Best Efforts to ensure that the terms and conditions of this Agreement are complied with by the Parties and, upon the Effective Date and annually thereafter, that each such officer
execute a certificate for delivery to DSS: (a) acknowledging the protective security measures taken by the Company to implement this Agreement; and (b) acknowledging that the U.S. Government has placed its reliance on him or her as a
resident U.S. citizen, and as a holder of a personnel security clearance, to exercise his or her Best Efforts to ensure compliance with the terms and conditions of this Agreement by the Parties. 

7.12. Inside Director Obligations and Certification.

 ARTICLE X - Duty to Report Violations of this Agreement 

10.01. The Parties to this Agreement, except DoD, agree to report promptly to DSS all instances in which the terms and obligations of this
Agreement may have been violated. 
 CONTACTS AND VISITS 

ARTICLE XI - Visitation Policy 

11.01. Visit Requests. The Chairperson of the GSC shall designate at least one Outside Director, who shall have authority to review,
approve, and disapprove requests for Visits to the Company by all personnel who represent any of the Affiliates (except for any Company personnel who hold DSS-approved interlocking positions with the
Affiliate, and other than as contemplated in Section 2.01(j)), including all the directors, officers, employees, representatives, and agents of any of them. As used in this Agreement, the term “Visits” includes meetings at any
location within or outside the United States, including, but not limited to, any facility owned or operated by the Company (and its Controlled Entities) or any of the Affiliates, and at the discretion of the GSC, may also include certain
videoconferences and teleconferences. The designated Outside Director shall also have authority to review, approve, and disapprove requests for proposed Visits to any of the Affiliates by all personnel who represent the Company (including all of its
directors, officers, employees, representatives, and agents, except for each Inside Director, if any, who is deemed to represent the Affiliates for purposes of this Agreement), as well as Visits between or among such personnel at other locations.
Each visit by 

  
 15 








 
an Inside Director, if any, must be approved by the designated Outside Director, unless the visit is to attend Company Board meetings or Company Board committee meetings. A record of all visit
requests, including the decisions to approve or disapprove, and information regarding consummated Visits, such as the date, place, personnel involved, and summary of material discussions or communications, shall be maintained by the designated
Outside Director and shall be periodically reviewed by the GSC and DSS. 
 11.02. Approval of Visit Requests. Except for certain
Routine Business Visits, as defined in Section 11.05 below, all Visits must be approved in advance by one of the Outside Directors designated by the GSC Chairperson to act on such matters. All requests for Visits shall be submitted or
communicated to the FSO for routing to the designated Outside Director. Although strictly social Visits at other locations between Company and Affiliate personnel are not prohibited, written reports of such Visits must be submitted after the fact to
the FSO for filing with, and review by, the designated Outside Director and the GSC. Visits that exceed 30 consecutive business days or that cumulatively exceed 200 days in a single year shall also require DSS approval. 

11.03. Procedure for Approval of Visit Requests. A written request for approval of a visit must be submitted to the FSO prior to the
date of the proposed visit. The GSC will establish in the Company’s visitation procedures reasonable standards for the Company in connection with the lead times required for requests and notifications required under this section. If a written
request cannot be accomplished within the GSC approved timeframe because of an unforeseen exigency, the request may be promptly communicated to the FSO and immediately confirmed in writing; however, the FSO may refuse to accept any request submitted
with less than the required advance notice if the FSO determines that there is insufficient time to consider the request. The GSC shall determine what constitutes an unforeseen exigency for these purposes. The exact purpose and justification for the
visit must be set forth in detail sufficient to enable one of the designated Outside Directors to make an informed decision concerning the proposed visit, and the FSO may refuse to accept any request that the FSO believes lacks sufficient
information. Each proposed visit must be individually justified and a separate approval request must be submitted for each. 
 11.04. The FSO
shall advise one of the designated Outside Directors of a request for approval of a visit (other than a bona fide request for a Routine Business Visit, defined below) as soon as practicable after receipt of the written request. The designated
Outside Director shall evaluate the request as soon as practicable after receiving it and may approve or disapprove the request, or disapprove the request pending submission of additional information by the requester. The Outside Director’s
decision shall be communicated to the requester by any means, but it shall be confirmed in writing, when practicable, at least one day prior to the date of the proposed visit, but in no event later than six (6) calendar days after its receipt
by the FSO. A chronological file of all documentation associated with meetings, visitations, and communications (e.g., contact reports), together with records of approvals and disapprovals, shall be maintained by the FSO for inspection by DSS.
During each GSC meeting, the Outside Directors shall review such documentation filed since the last meeting to ensure adherence to approved procedures by the requesters and the designated Outside Director and to verify that sufficient and proper
justification has been furnished for approved Visits. 

  
 16 








 11.05. Routine Business Visits. 

a. Routine Business Visits, as defined in Section 11.05.b. below, may be approved by the FSO, in the FSO’s discretion, without advance
approval by one of the designated Outside Directors. Requests for Routine Business Visits must be submitted in writing and in advance to the FSO, and shall state the basis upon which the requester deems the visit to be a Routine Business Visit. Such
requests must include sufficient information to enable the FSO to make an informed decision concerning the proposed visit. The FSO, in the FSO’s discretion, may refuse to accept any request that the FSO believes lacks sufficient information and
may refer any request to the designated Outside Director for evaluation, notwithstanding its designation as a Routine Business Visit request. Any request that the FSO believes is not properly characterized as a Routine Business Visit shall be
referred to the designated Outside Director, who shall evaluate the request in accordance with the terms of this Agreement. 
 b.
“Routine Business Visits” are those that pertain only to the commercial aspects of the Company’s and its Controlled Entities’ business, are made in connection with the regular day-to-day business operations of the Company and its Controlled Entities, and do not involve Company Principals, senior officials of the Affiliates, the transfer or receipt of classified information or
Export Controlled Information or activities bearing upon the Company’s or its Controlled Entities’ performance of classified contracts. Routine Business Visits may include: 

(i) Visits for the purpose of discussing or reviewing such commercial subjects as the following: company performance versus plans or budgets;
inventory; accounts receivable; accounting and financial controls; and implementation of business plans and technical development programs; 

(ii) Visits of the kind made by commercial suppliers regarding the solicitation of orders, the quotation of prices, or the provision of
products and services on a commercial basis; 
 (iii) Visits concerning fiscal, financial, or legal matters necessary for compliance with
the requirements of any foreign or domestic governmental authority responsible for regulating or administering the public issuance of, or transactions involving, stocks and securities; and 

(iv) Visits concerning marketing and technical activities relating to the import or export of products necessary for compliance with the
regulations of U.S. departments or agencies, including but not limited to the Departments of Defense, Commerce, State, and Treasury. 

11.06. Special Provision Concerning Controlled Entities. Anything foregoing to the contrary notwithstanding, the notice and approval of
visitation restrictions contemplated in this Agreement shall not apply to Visits between personnel of the Company and personnel of the Controlled Entities. However, Visits between the Controlled Entities and any Affiliate shall be subject to the
visitation approval procedures set forth herein. 

  
 17 








 11.07. Discretion to Alter Notice or Approval Requirements. Notwithstanding the above, the
GSC, in its reasonable business discretion and consistent with its obligation to safeguard classified information and Export Controlled Information in the Company’s possession, may with the approval of DSS: 

a. designate specific categories of visit requests other than those enumerated above as Routine Business Visits not requiring the advance
approval of the designated Outside Director; or 
 b. determine that, due to extraordinary circumstances involving the security of classified
information and/or Export Controlled Information, certain types of Visits that might otherwise be considered Routine Business Visits under the terms of this Agreement are to be allowed only with the advance approval of the designated Outside
Director. 
 11.08. Quarterly GSC Meetings. The Chairperson of the GSC shall provide, to the extent authorized by this Agreement, for
regular quarterly meetings of the GSC. At the discretion of the GSC, representatives of the Affiliates and the Company’s management personnel may be invited to attend. 

11.09. Maintenance of Records for DSS Review. A chronological file of all visit requests, reports of Visits, and contact reports,
together with appropriate approvals or disapprovals pursuant to this Agreement shall be maintained by the GSC for review by DSS.
