SECTION 2. SERVICES; DESCRIPTION OF WORK

Section 2.1. Markets and Deployment. Contractor has been engaged to provide Company with certain coordination,
management, Site identification, analysis and acquisition, Site development services, engineering, procurement and construction and/or program management services in connection with the creation and expansion of Companys terrestrial wireless
network (the Network). The foregoing services and Contractors responsibilities are described herein, including in Exhibit BandExhibit C attached hereto. Contractor will provide such services
in Markets identified by Company from time to time pursuant to purchase orders (each a Purchase Order or PO). Contractor shall provide the goods and services under each PO, on the terms and
conditions of this Agreement. In order for a PO to be effective it must be accepted by Contractor. POs issued to Contractor shall be deemed accepted by Contractor unless Contractor otherwise notifies a Company Authorized Representative in writing
within three (3) Business Days after Contractors receipt thereof. Company may deliver POs electronically.

Section 2.2. Limited Exclusive Rights.

(i) Except as may be specifically provided otherwise herein, but
without limiting the effect of Section 10.2, Section 10.3 or Section 10.4 of this Agreement (to the extent applicable), Companys engagement of Contractor is at will. Company shall provide Contractor the opportunity
to perform Site Deployment Services set forth in Exhibit C at no less than six hundred and fifty (650) Sites in one or more Metropolitan Markets selected by Company in its sole discretion. Company does not guarantee Contractor any
additional minimum level of Work or level of compensation hereunder. Subject to the foregoing, and subject to the terms of this Agreement, including those pertaining to the instruments and procedures for the issuance of Work, Company hereby engages
Contractor to perform the Site Deployment Services set forth in Exhibit C for such number of Sites as Company may determine in its sole and absolute discretion, in one or more of the market areas set forth in Exhibit A (the
Markets) as selected by Company. Provided that an Event of Default or an Event of Release from Exclusivity (as defined in Exhibit E) or a Change of Control has not occurred, Company agrees that it will not,
during the initial three-year term, engage any third party to perform such Site Deployment Services in the Markets or any Metropolitan

Market prior to fulfilling Companys obligation to provide Contractor the opportunity to perform Site Deployment Services at no less than six hundred
fifty (650) sites in one or more Metropolitan Markets selected by Company (collectively, the commitment in this sentence together with the commitment in the second sentence of this Section 2.2 are referred to as the Exclusivity
Obligations). If any of the events listed in the preceding sentence has occurred, Company will be fully released from its Exclusivity Obligations. Company shall be obligated to pay Contractor, in accordance with the applicable pricing
and invoicing procedures set forth in this Agreement, for Work actually authorized by Company and performed by Contractor or its approved subcontractors under this Agreement. Company may, from time to time, offer to award Contractor with the right
to perform Work for a specified number of Sites in one or more Metropolitan Markets outside of the Markets set forth in Exhibit A in order to fulfill the Exclusivity Obligations set forth herein; provided that pricing and the number of Sites are
agreed in advance. The parties shall negotiate in good faith to reach agreement on the pricing that will apply for such additional Work. If the Parties cannot agree on such pricing through good faith negotiations within fifteen (15) days after
commencement thereof, Contractor shall have the option to either (i) decline the additional Work, in which case Companys Exclusivity Obligations shall be reduced by the number of Sites that were included in Companys offer;
(ii) offer to perform the Work at the pricing applicable to the Baltimore/Washington Market; or (iii) escalate the matter to the Management Committee for further discussion in accordance with the procedures set forth in Section 26.1
 26.3, provided that, in this case, all such discussions must be completed within fifteen (15) additional days. If Contractor elects option (ii), TerreStar may elect in its sole discretion to decline to proceed with the Work. In any case,
if the parties have been unable to reach agreement on the pricing that would apply for the Work within thirty (30) days from the date such pricing discussions initially commenced, Company shall thereafter be free to award the Work to a third
party, provided that Customers Exclusivity Obligations shall continue in full force and effect. Notwithstanding the preceding, if at the end of the initial three-year term of this Agreement, Company has failed to meet its Exclusivity
Obligations as a result of the parties failure to reach agreement on pricing for Work in Metropolitan Markets that was first offered to Contractor and that would have otherwise applied to satisfy Companys Exclusivity Obligation,
Companys Exclusivity Obligations shall be reduced by the number of Sites that were included in such offers, so long as Company has fully satisfied its obligation to first offer Contractor with the opportunity to perform Site Deployment
Services for Sites within Metropolitan Areas throughout such three-year period. Notwithstanding anything to the contrary in this Agreement, Company shall have no liability to Contractor or any third party for any failure of Company to fulfill its
Exclusivity Obligations to the extent resulting from (a) Companys election to build out less than six hundred and fifty (650) Sites in Metropolitan Markets during the initial three-year term of this Agreement, or (b) termination
of this Agreement pursuant to Sections 10.2, 10.3 or 10.4 prior to Company having fulfilled its Exclusivity Obligations. If Contractor is issued a PO for any Site which is then land banked or otherwise suspended by Company for any reason other than
Contractors breach, and which Company within twelve (12) months after land banking or suspending the Site determines to proceed with, provided that an Event of Release from Exclusivity has not occurred prior to or after Companys
determination, Company will not engage any third party other than Contractor to perform that Work.

Work (the term Notice to Proceed when used in this Agreement shall mean any notice to proceed issued in conformance with the requirements of the applicable Exhibit); (e) a description of agreed performance and
Deliverables milestones (Milestones) that must be achieved as a condition to Contractors right to earn compensation for Base Cell Site Unit Price-based payments in accordance with this Agreement; and (f) such
other matters as the Parties may agree. Exhibit E sets forth the service levels that Contractor guarantees in the performance of the Work and the agreed upon consequences for failure to meet such service levels (Service Level
Agreements or SLA).

Section 2.4. Standards of Performance.
Contractor agrees to perform all Work in a timely professional and workmanlike manner in compliance with all Laws, using personnel possessing the requisite skill, training and expertise to perform the Work. Contractor shall establish appropriate
oversight and quality assurance procedures (which shall be described to Company in accordance with Section 3.4 hereof) to ensure that all Work is carried out in accordance with all Applicable Requirements.

Section 2.5. Provision of Resources. Except as otherwise expressly provided in this Agreement, Contractor will be
responsible for providing all personnel, tools, supplies, equipment, software, systems, know-how and other resources of whatever kind or nature as are necessary to complete the Work on schedule, on budget, and in accordance with the Applicable
Requirements and SLAs.

Section 2.6. Procurement of Materials. As authorized by any PO, Contractor shall
procure material, equipment, supplies and other items necessary to complete the Work (Materials). At Companys direction, Contractor shall procure such Materials using either of the following methods, at the sole
discretion of the Company: (a) Contractors commercially reasonable efforts to purchase such Materials at the lowest prices commercially available to Contractor (including any discounted pricing available to Contractor under
Contractors supply contracts or similar arrangements) or (b) as Companys agent, using Companys volume discounts under Companys then existing vendor relationships. Contractor shall deliver to Company such bills of sale
and other documents as Company may reasonably request related to such purchases. Contractor shall charge Company for Materials as set forth in Exhibit F. All Materials will be of good quality, new, of current manufacture and fit for their
intended purpose. If required by Company, Contractor shall furnish satisfactory evidence as to the kind and quality of Materials. Where Materials carry a warranty, Contractor shall take all actions necessary for the effectiveness thereof and shall

Section 2.7. Network Equipment Contract.

(i) Contractor acknowledges that Company has entered into or will enter into contracts for terrestrial network design and equipment delivery (the
Network Equipment Contract), Site leases and telecommunications services agreements with one or more third-party vendors (each, a Network Vendor), whereby the applicable Network Vendor agrees to
provide certain equipment or certain design or other services as part of the development and operation of the Network, the lease of a Site or provision of communications services for a Site. Contractor shall coordinate with Company and the Network
Vendors to establish for each Market a schedule at the Site level (the Deployment Schedule) for the delivery, installation and connection by the Network Vendors of all goods, services, labor and equipment necessary for the
timely development of the Network in that Market and ensure the Work in each Market is performed in accordance with the Deployment Schedule and Throughput Model (defined in Section 3.2). The Deployment Schedule shall be subject to the approval
of Company. Company shall either approve the Deployment Schedule or provide comments within ten (10) days of receipt thereof and, once the comments are resolved and if the comments are to be incorporated into the Deployment Schedule, the
approval procedure shall be repeated.

(ii) Contractor shall be responsible for coordinating with Network Vendors and Company to ensure
that all parties adhere to the Deployment Schedule and Throughput Model for each Market (and this responsibility shall for all purposes hereof be considered part of the Work). If any Network Vendor is ready and able to make a delivery of equipment
(Network Equipment) or other services required by the Deployment Schedule for a Market and, as a result of Contractors failure to complete applicable Work on time, completion of the applicable Site cannot safely and
properly accommodate the Network Equipment or connection of services, Contractor shall be responsible for the payment of any penalties or damages owed by Company to the applicable Network Vendor as set forth in Exhibit I.

(iii) Contractor shall be responsible for coordinating with the Network Vendors and their representatives in a manner that will ensure the
orderly deployment of Network Equipment to each Site being developed under this Agreement and connection of such Site to the services of Network Vendors. Contractor, Company and the applicable Network Vendors shall establish, within thirty
(30) days after the issuance of an applicable PO, an agreed Deployment Schedule for that Market. Contractor shall cooperate with all Network Vendors and other Company suppliers, service providers and contractors as appropriate to enable the
timely and efficient completion of the Site Services for each Site and the build-out of Companys terrestrial wireless network. If Company requests Contractor to provide material additional cooperation beyond what is specified in this
Agreement, such cooperation shall be provided at Companys expense. The Scope of Work in Exhibit B establishing the Program Management Office shall designate a director (the Program Director), who shall
have primary responsibility for working out any disputes, disagreements, discrepancies, performance conflicts or other issues that arise between Contractor and any Network Vendor (Network Deployment

Issues). Resolution of all Network Deployment Issues shall be resolved by the Program Director in a prompt and efficient manner, in order
to maintain the Deployment Schedule. Company shall require that the Network Vendors interface with the Program Director.

(iv) If the
Program Director becomes aware of a Network Deployment Issue that the Program Director is unable to resolve in a manner that will avoid delays in the Deployment Schedule, the Program Director shall, in as timely a manner as possible to avoid such
delays in the Deployment Schedule, provide to the Company designated representative (the Company Designated Representative) a detailed description of the conflict and the positions of both Contractor and the Network Vendor
concerning such Network Deployment Issue. The Company Officer shall, within two (2) Business Days after receipt of the foregoing description make a decision concerning how the Network Deployment Issue is to be resolved, which the Company
Officer shall describe in a written or e-mailed notice to Contractor and the Network Vendor. Such decision may require Contractor or applicable Network Vendor to perform any work or provide any item needed for Company to resolve the Network
Deployment Issue. Subject to Section 23, Company shall have the right to require Contractor to perform such work or provide such item while the Parties further consider the matter of which entity was actually responsible to do so;
provided, further, in the event the work or the item would by its nature involve Materials or Pass-Through Costs, Company shall make payment to Contractor relating to the work or item (but excluding any associated management services
or Contractor fee) pending resolution of the issue. If the performance of such work or provision of item is a change to the work described under Exhibit C for which Contractor receives a Base Cell Site Unit Price-based payment, Company
will pay Contractor for the performance of such work or provision of item on a time and materials basis, using the applicable hourly rates set forth in Exhibit F, Attachment 3 or such other mutually agreed basis.

Section 2.8. Company Responsibilities.

Company shall be responsible, either directly or through its Network Vendors or other third party contractors, for those activities or actions that are described in Exhibit C as being the responsibility of
Company, its Network Vendors or other third party contractors.

SECTION 3. PROJECT MANAGEMENT AND DEPLOYMENT

Section 3.1. Program Management Office. Contractor shall assemble and maintain a team of qualified personnel (the
Program Management Office or PMO) to provide national oversight and coordination of all aspects of the Network design, Site acquisition, construction, and installation services (excluding
installation of the Network Equipment (but including installation of platforms for the attachment of Network Equipment)), and other design and installation tasks as assigned by Company to Contractor or to other vendors in connection with the Network
(regardless of whether Contractor is performing any other services in a given Market).

The Program Management Office shall be responsible for ensuring that Work is performed in accordance with the Throughput Model (as defined in
Section 3.2 below) and the Deployment Schedule and that all applicable Milestones and Applicable Requirements are met. The responsibilities of the Program Management Office, the Work that the Program Management Office is required to perform,
requirements concerning the qualifications of personnel, the number of authorized Program Management Office personnel for which Contractor may charge Company from time to time, requirements concerning Key Positions or Key Personnel and the manner in
which Contractor shall maintain the Program Management Office and provide the services thereof are described in the Scope of Work attached hereto as Exhibit B.

Section 3.2. Site Deployment Services; Network Deployment.

(i) In furtherance of its performance of the Site Deployment (also referred to herein as Radio Access Network (RAN) Management)
and RAN network and deployment Work described more fully in Exhibit C, Contractor shall assemble and maintain in each Market a team (each, a Market Deployment Team) to coordinate and manage (in coordination
with, and without duplication of services provided by, the Program Management Office) all Work awarded to Contractor in a designated Market. Each Market shall have its own dedicated Market Deployment Team, which shall operate under the supervision
and control of the Program Management Office to ensure the proper, timely and orderly completion of Work in the applicable Market. Subject to the terms set forth in Exhibit C, the Market Deployment Team shall be responsible for assisting
Company in the identification, acquisition and/or construction of appropriate towers, rooftops, ground leases, or other appropriate locations or facilities (each, a Site) for installation of all facilities, installations,
hardware and platforms (Installations) necessary for Company or the applicable Network Vendors to install the Network Equipment, including the supervision, coordination and management of all construction and installation
activities included in the Work, the completion of all punch-list work and all other activities necessary to cause each Site to become operational in accordance with the Deployment Schedule. Each Site shall be subject to Companys approval in
Companys sole discretion, and shall be identified, selected and approved in accordance with the procedures described in Exhibit C. The terms on which Contractor shall identify and acquire Sites and coordinate the installation of
the Installations (including, if mutually agreed by the Parties, the construction of new facilities) are set forth in Exhibit C. The linear progression of approval points, conditions precedent to proceeding to each step in the process of
Site Deployment, and the necessary Deliverables for the completion of the Work to the satisfaction of the Company are as described in the various Exhibits attached to this Agreement. Contractor shall not proceed beyond necessary approval points nor
take actions which might incur cost or liability to Company with regard to any Site without first obtaining such approval as outlined in the applicable Exhibit(s), including but not limited to a Notice to Proceed with Site Acquisition (the form of
which is set forth in Exhibit C, Attachment 4) and a Notice to Proceed with Construction (the form of which is set forth in Exhibit C, Attachment 10).

(ii) Contractor shall perform the Site Deployment Services and deploy the RAN Network in accordance
with version number 1 of the throughput model (as such model may be revised by mutual agreement of the Parties from time to time, the Throughput Model). The Throughput Model shows the schedule for Contractors
completion of the Milestones set forth in Exhibit C,(and completion of tasks required for such Milestones) as required for RAN network deployment for each Market and for all Markets, by month and cumulatively. Any change to the
Throughput Model shall be subject to Companys prior written approval. If Company approves any change, the revised Throughput Model will not take effect until the month immediately following Companys written approval; provided,
however, the guaranteed volumes (i) in the prior version of the Throughput Model for the month(s) preceding the month in which Contractor has requested a change shall remain unaffected and (ii) the month in which Contractor has
requested the change, and the succeeding month(s) if Company is still reviewing the change, shall be adjusted, to the extent required by the change, for the purpose of not penalizing the Contractor in calculating Contractors Service Level
Agreement performance during such Measurement Period.

Section 3.3. Staffing; Key Positions. Contractor
agrees to provide the Program Director and other personnel as may be described as Key Personnel (Key Personnel) in Exhibit B and Exhibit C or otherwise relating to the Program Management
Office or the particular Market Deployment Teams in the numbers and at the times as further described herein. All Key Personnel shall be full-time professionals that have been pre-approved in writing by Company. Contractor shall employ such other
qualified professionals or other personnel as are necessary to properly perform Contractors obligations under this Agreement. All Key Personnel must be direct employees of Contractor. Prior to hiring or assigning any Key Personnel to the Work,
Contractor shall furnish Company with a resume of the proposed candidate for Companys review and, if requested by Company, the opportunity to interview such candidate. Company shall have thirty (30) days after completion of such
activities to notify Contractor of any objections that Company has to such candidates assignment. If Company objects to such assignment, Contractor and Company shall use commercially reasonable efforts to resolve Companys concerns. If
the Parties are unable to resolve such concerns within five (5) days of Companys objection, Contractor shall propose another individual for Companys approval in accordance with the foregoing procedure. No Key Personnel may be
assigned to the Work without Companys express prior written consent, which shall not be unreasonably withheld. Unless Company waives this requirement in its sole discretion, all Key Personnel shall be identified before Contractor is authorized
to commence Work pursuant to a PO. Contractor agrees that it will not, without Companys prior written consent (which Company shall be under no obligation to grant), voluntarily remove any Key Personnel during the performance of the Work for
which he or she is responsible. Contractor shall use commercially reasonable efforts to retain personnel in non-key positions, to assure consistent staffing. If Company objects to the continued assignment of any Contractor personnel (including, but
not limited to Key Personnel) to this Agreement, Contractor shall promptly remove such personnel and provide a replacement in a timely manner. Contractor shall use commercially reasonable

efforts to minimize turnover of personnel assigned to the completion of Work. Contractor shall provide to Company written notice fifteen (15) days prior
to reassigning or replacing Key Personnel. Contractor shall ensure that no Contractor PMO Key Personnel involved in the Work are engaged in the provision of services by Contractor to any Adverse Party during the performance of the Services by such
personnel. Except for a replacement at the request of Company or a reassignment necessitated by circumstances beyond the control of Contractor, for example, death, disability or the employees family circumstances, Contractor shall not reassign
or replace any Key Personnel without Companys prior written consent, which may be withheld in Companys sole discretion unless Contractor demonstrates to Companys reasonable satisfaction that such reassignment or replacement will
not have an adverse effect on the Work. The Parties shall agree from time to time on the appropriate number of Key Personnel and other personnel of particular classifications necessary during specified periods for Contractor to deliver all services
required by the Program Management Office. Company and Contractor shall also review Program Management Office staffing requirements on a regular basis, but at least quarterly, and sufficiently in advance of any significant anticipated changes so as
to permit Contractor to plan and respond to PMO staffing needs (e.g., typically one (1) month in advance of each calendar quarter) and as further set forth in Section 1.1.3 of Exhibit F. Company will issue a PO or PO revision
reflecting any agreed PMO staffing changes in a timely manner such that approved staffing levels are adequately funded. Contractor shall update the list of Key Personnel as of the beginning of each calendar quarter.

(i) With regard to Work set forth under the Scope of Work attached hereto as Exhibit C, Contractor shall be free to enter into any subcontract awarded in accordance with Contractors established
practices and procedures and in accordance with all requirements set forth in Exhibit C; provided, however, that within thirty (30) days after the Effective Date of this Agreement and prior to entering into any
subcontract, Contractor shall provide to Company written notice of its initial list of desired subcontractors, including the subcontractors name and nature of work being subcontracted. Thereafter, Contractor shall provide Company on a periodic
basis as mutually agreed, but at least on a quarterly basis, with a list of its desired additional subcontractors. Contractor agrees to provide to Company such other information as Company may reasonably request. If Company objects to any proposed
subcontractor, Company shall notify Contractor within ten (10) Business Days after receipt of Contractors list and the Parties shall thereafter meet within five (5) days to resolve the objection. If after meeting, the Company acting
reasonably still objects to the subcontractor, Contractor will furnish an alternate subcontractor for Companys approval. If the Company does not object to Contractors proposed list within ten (10) Business Days, the list shall be
deemed as accepted by Company. Contractor shall not subcontract any PMO services set forth in Exhibit B without the prior written approval of Company. For other subcontractors, Contractor shall obtain Companys approval in accordance
with Section 4.2.

(ii) Notwithstanding Section 4.1(i) above, Contractor may subcontract portions of the Work to its
Affiliates without the prior written approval of Company. Without limitation, Contractor shall have the right to subcontract to its related professional engineering companies that are Affiliates of Contractor any professional engineering services
required by each applicable state to be performed by a professional engineering firm registered in such state as required by its law. Contractor hereby guarantees to Company that such entities will comply with the responsibilities and obligations
herein assumed by Contractor and Company agrees that it shall hold only Contractor responsible for any failure to so comply. Contractor agrees that Company will incur no duplication of costs or increased taxes resulting from any such subcontract and
shall indemnify and hold Company harmless from any such costs or taxes. Company agrees that the limitations on Contractors liability set forth in this Agreement apply to Contractor and its Affiliates.

Section 4.2. Other Subcontractor Selection. Where services, such as Contractor acting as agent for Company for the
purchase of Materials or Company otherwise requests Contractor to solicit bids for and on behalf of Company, Contractor shall provide to Company, within three (3) days after receipt, true and complete copies of

all bids received by Contractor for the performance of the project. All bids shall be accompanied by (i) all information necessary for Company to
ascertain the nature and scope of the services to be provided thereunder and the cost thereof and to make a meaningful comparison of the scope of work and pricing in the various subcontracts and shall further be accompanied by
(ii) Contractors recommendation as to which of the bids it recommends that the Company select. If Contractor does not select the lowest bid as its recommended bid, the Contractors recommendation shall include a detailed description
of the reasons therefor. If Company rejects all bids and requests further services, Contractor shall, within fifteen (15) days after receipt of Companys notice, obtain at least two (2) additional bids for Companys
consideration.

Section 4.3.Contractor Parties. For purposes of this Agreement, Contractor

contract with Contractor or any subcontractor, or otherwise performing Work with the consent of Contractor or any other Contractor Party, or for whose acts Contractor or any other Contractor Party may be liable. Contractors responsibility
shall extend to all Contractor Parties, whether or not engaged, appointed or selected in accordance with this Agreement, but this sentence shall not render valid any arrangement with a Contractor Party that is not entered into in compliance with
this Agreement. Contractor will not be relieved of its obligations under this Agreement by use of any Contractor Party to perform Work and will be responsible for any Contractor Partys failure to satisfy the terms of this Agreement, as they
relate to the Work performed by the Contractor Party, to the same degree as if Contractor performed the Work directly. If Company determines that the performance or conduct of Contractor or any Contractor Party is unsatisfactory, Company may notify
Contractor of its determination in writing, indicating the reasons therefor, and Contractor will promptly take all actions necessary to remedy the performance or conduct of Contractor or such Contractor Party. At Companys request, Contractor
shall, at no cost to Company, terminate any arrangement with any Contractor Party that was not entered into in accordance with this Agreement.

Section 4.4. Step-In Rights. Each subcontract entered into in furtherance of Site Deployment Services described in Exhibit C shall contain a provision by which the subcontractor or other counterparty
thereto agrees that, upon delivery of notice from Company that an Event of Default has occurred under this Agreement or that this Agreement has been terminated due to an Event of Default with respect to the Work to which the subcontract relates,
that the subcontract may be assigned to Company and thereafter Company may assert the rights and obligations of Contractor under such subcontract, to the extent arising after the date of such assignment. Contractor shall use all reasonable efforts
to provide that each subcontractor shall further provide that, if Contractor is in default of its payment obligations under any subcontract, the subcontractor shall not stop work or terminate the subcontract without first giving Company notice of
Contractors default and ten (10) days opportunity to cure the default and assume Contractors obligations under the subcontract. Contractor agrees that

Company shall have that right upon the occurrence of an Event of Default or the termination of this Agreement due to an Event of Default with respect to such
Work, to assume the rights, obligations and responsibilities of the Contractor under the subcontract from and after such date. Contractor shall immediately notify Company of any Contracting Partys breach of contract claims against Contractor

expenses and costs associated with the creation of systems, software, interfaces, modification of its information technology systems, and training of Contractors personnel in the use of the electronic information technology processes and
procedures required to satisfy the information and data collection and uploading requirements required to support Companys Site Management System or interface with [***]. Contractor shall provide appropriate training to Company personnel as
necessary for such Company personnel to fully access subcontractor pricing, bidding and other information in the Contract Management System.

set forth in this Agreement, Contractor shall promptly notify Company of such inoperability or unavailability and shall promptly identify and implement substitute methods of accomplishing the same requirements on terms acceptable to Company at
Companys reasonable discretion. This provision shall not relieve Contractor of any of its obligations hereunder, including without limitation, those of Section 4 hereof.

software, interfaces, modification of its information technology systems, and training of Contractors personnel in the use of the electronic information technology processes and procedures required to satisfy the information and data
collection and uploading requirements set forth in and required by the Site Management System and, to the extent they do not differ from Contractors standard systems and applications, Companys other reasonable requirements.

Section 7.4. Data and Reports. In addition to any other reports that may be required in this Agreement, Contractor
agrees to provide any reports that may be reasonably required by Company, at no cost to Company. By submitting any report or other Deliverable, Contractor shall be deemed to have certified to Company that such report or other Deliverable is
accurate, current and complete in all material respects. The reports are and shall remain the sole and exclusive property of Company. The reports shall not be used by Contractor Parties or disclosed, sold, assigned, leased, or otherwise provided to
third parties by Contractor Parties, except to the limited extent necessary to

complete the Work, nor shall any of the foregoing be commercially exploited by or on behalf of Contractor Parties. At Companys request and sole
discretion, and as directed by Company, Contractor shall promptly correct any errors or inaccuracies in any reports delivered pursuant to this Agreement. Reports shall be delivered in such media and format as Company shall direct and shall include
pricing, cost and other data concerning all work that will permit Company to ascertain with full visibility the actual cost related to Materials, and Pass-Through Costs covered by any Contractor Invoice. Upon request by Company at any

applicable statute of limitations or, in accordance with Contractors records retention policies. Contractors archived data shall not be used for any purpose other than as a backup of data elsewhere in the Contractors system.

SECTION 8. DELAYS AND EXTENSIONS OF TIME; LIMITATIONS

Section 8.1. Contractor Delays. Exhibit E sets forth the certain consequences for Contractors failure
to perform the Work and complete certain Milestones in accordance with the Throughput Model. Exhibit I sets forth the certain consequences for Contractors failure to perform the Work to support Company Network Vendors. Liquidated
damages and other amounts payable as set forth in Exhibit E and Exhibit Iand Companys remedies described in Section 10.3 are the sole and exclusive remedies of Company for Contractors failure to perform the Work in
accordance with the Throughput Model or to support the Network Vendors.

Section 8.2. Excusable Delays.
For purposes of this Agreement, Force Majeure shall mean any event or circumstance, or combination of events or circumstances, that arises after the date hereof, is beyond the reasonable control of the Party claiming Force
Majeure, or could not be prevented or overcome by the reasonable efforts and due diligence of the Party claiming Force Majeure and has an impact which will actually, demonstrably, and adversely affect such Partys ability to perform its
obligations in accordance with the terms of this Agreement, including but not limited to, acts of God or of the public enemy, terrorist attacks or threats thereof, epidemics, unavoidable casualties, or unavoidable and unusual delay in obtaining
equipment or materials (which delays are outside Contractors reasonable ability to control), disruptions to transportation systems, strikes (except for those associated with employees of any Contractor Party). An Excusable
Delay is any delay in the completion of Work that is due to (i) Force Majeure or (ii) Companys material failure to perform its obligations under this Agreement. If an Excusable Delay occurs, the schedule for completion
of any element of the Work that is affected thereby shall be extended to such date as shall reasonably account for the impact of the Excusable Delay. If Contractor

19



---

Execution Copy



wishes to rely upon an Excusable Delay as a basis for seeking any extension of time under an agreed Work schedule, it shall notify Company in writing within
five (5) calendar days after the beginning of any Excusable Delay, stating with specificity the cause of the delay, the specific elements of the Work that are impacted, the specific areas involved, and the anticipated period of delay. If
Contractor fails to give Company such written notice within such five (5) day period, the period of Excusable Delay shall not commence until such notice is received by Company. Upon receipt of such notice, Company shall determine whether an
extension is justified and, if so, the Parties shall discuss an equitable extension, generally day for day, of the applicable date(s) of completion, taking into account not only the expected duration of the Excusable Delay, but also its reasonable
impact on Contractors ability to complete the Work for which Contractor is responsible; provided, however, that Company shall, subject to Section 26, make the determination of the extension reasonably required to reflect the
impact of any Excusable Delay on Contractor and the Work. Company shall have the option to deny any request for extension or for additional costs absent a showing that the event of Excusable Delay will cause an actual delay in the Work schedule or
result in additional costs. Contractor shall not have any right in connection with Force Majeure to a modification of the pricing or reimbursement provisions applicable to the Work or to any provisions relating to additional payments or fees except
to the extent Contractor demonstrates that the event is of a magnitude that affects a majority of Sites in one or more Markets. The Parties agree that except as otherwise excused under this Agreement (i) the unwillingness or inability of
Contractor or any Contractor Parties to perform any obligation under this Agreement, (ii) any labor actions affecting a Contractor Party and based on a Contractor Partys own employment program (as compared to an industry-wide labor
action), (iii) unavailability of Materials that could have been avoided by proper project management procedures, (iv) bankruptcy or insolvency actions affecting a Contractor Party, (v) litigation or administrative actions affecting a
Contractor Party (except if initiated by the Company) or (vi) the unwillingness or financial inability of Contractor or any of its subcontractors, vendors, or suppliers to perform any obligation hereunder or under any applicable subcontract or
supply contract, shall not be grounds for an Excusable Delay. Further, the occurrence of an Excusable Delay due to Force Majeure shall not excuse Contractors obligation to pay to Company any amounts due to Company prior to or during the
Excusable Delay.

SECTION 9. INSPECTION, CORRECTIONS AND ACCEPTANCE OF WORK

Section 9.1. Inspection. Company, or a third party consultant or other representative of Company, may inspect any
Deliverable, Site or other Work performed by Contractor prior to Companys acceptance thereof in accordance with Exhibit C with respect to such Work. In furtherance of the foregoing, Contractor shall afford Company, or a third party
consultant or other representative of Company, access to any Site to the full extent and at such times as Contractor has access to the Site. Contractor shall be required, without regard to the state of completion to promptly correct any Deliverable,

in that it does not meet the warranty standards set forth in Section 19.2 or is not in compliance with the Applicable Requirements. For the avoidance of
doubt, any Work required to be corrected by Contractor under this Section that has not been completed prior to acceptance in accordance with Exhibit C shall not excuse Contractor from the obligation to correct such Work under
Section 19.4.

Section 9.2. Company Correction Cost. If Contractor does not repair any Deliverable,
Site or Work that is found to be defective, incorrect or non-conforming within five (5) Business Days after notice from Company or, to the extent such Work is not reasonably capable of being repaired within such five (5) Business Day

directly from Contractor, the full cost to repair the same, including, but not limited to, storage and removal costs, repair and installation costs, and material costs resulting from Contractors failure to make such repairs within the
timeframes described above.

Section 9.3. Acceptance. The inspection of the Deliverables, Sites and other
Work and the acceptance by Company thereof shall follow the procedures and requirements set forth in Exhibit C, in addition to those set forth in this Section 9.

(iv) if a mechanics or materialmans lien or notice of lien is filed against any part

Contractor in this Agreement or in any report, certificate, financial statement or Deliverable furnished by Contractor in connection with this Agreement shall be substantially untrue in any material respect as of the date such representation or
warranty was made provided Contractor does not cure such breach to Companys reasonable satisfaction within sixty (60) days after receipt of written notice of breach from Company (which termination shall be effective on the sixty-first (61st) day after the breach notice is received by Contractor, unless the breach is cured before such date); or

terminating the Agreement as a whole or any portion of the Work contemplated by this Agreement (or some combination of the foregoing). In the absence of any specification, Companys termination notice will be deemed to cover the Agreement as a
whole. In the event that a termination covers less than all of the Agreement, the components not terminated will continue in full force and effect. For any portion of the Work which is in process at the time of termination but which is not the

Section 10.4; and if terminated pursuant to Section 10.3 the costs provided for therein; provided, however, that any such payment

Contractor shall, unless Company specifies otherwise (a) terminate all orders and subcontracts relating to the performance of the Work affected by the termination, to the extent the same may be terminated without cost; (b) terminate and
settle, subject to approval of Company, other orders and subcontracts where the cost of termination and settlement will be less than costs which would be incurred if such orders and subcontracts were to be completed and assign such other orders or
subcontracts to Company; and (c) transfer to Company, in accordance with Companys directions, all materials, supplies, Work in progress, facilities, equipment, machinery or tools acquired by Contractor in connection with the performance
of such Work and for which Contractor has been paid hereunder (whether by transfer of funds or against Contractors liabilities to Company), together with all plans, drawings, working drawings, sketches, specifications and information for use
in connection therewith (including all copies thereof, as required elsewhere in this Agreement). If directed by Company, Contractor shall, to the extent stated in the notice of termination, take such actions to preserve the Work in progress and to
protect material, plans and equipment on the applicable Site or in transit thereto, and Contractor shall be entitled to reimbursement from Company for the reasonable costs thereof; provided, however, that if such termination is
pursuant to Section 10.1 or Section 10.4, Company shall have provided adequate financial assurances, acceptable to Contractor, as a condition to Contractors taking such actions.

Section 10.6. Transition. In the event of any termination or expiration of this Agreement or any portion of the Work,
Contractor will cooperate reasonably in the orderly wind-down of the Work being terminated or the transfer of the responsibility for such Work to another service provider. Contractor shall provide Company access to all information, data and records
relating to the Work, subject only to reasonable security and confidentiality procedures required to protect Contractors lawful proprietary rights. Except if the termination is the result of an Event of Default, Company may, at its discretion,
require Contractor to provide a transition period for Work not to exceed three (3) months, unless the parties mutually agree to a longer period; provided, however, in the case of termination by Contractor under Section 10.1,
Company shall have provided adequate financial assurances, in a form acceptable to Contractor, as a condition to Contractors taking such actions. If Company initially designates a transition period of less then three (3) months, it may
subsequently extend the transition period up to the maximum period of three (3) months with five (5) days written notice to Contractor. Company may, in its discretion, terminate the transition period upon five (5) days
prior written notice to Contractor. During the transition period, the Parties will continue to be bound by and perform in accordance with the terms

Partys actions result in the release of the Hazardous Material or otherwise resulting in a worsened condition of this Site, Contractor hereby releases
Company and Company Parties from, and agrees to indemnify, defend, and hold harmless Company and Company Parties from and against any and all claims, damages or expenses (including reasonable legal costs) including those for failure to comply with
all Laws, including without limitation all environmental Laws. For clarity under (ii) above, in the event Contractor performs a Phase I (ASME) and NEPA environmental analysis for a Site and in the performance of the Work as set forth in
Exhibit C, Contractor ignores or otherwise fails to alert Company of information set forth in the Phase I (ASME) and NEPA environmental analysis alerting it to the presence of Hazardous Material at the Site, Contractor shall be responsible
for the cost incurred by Company to have the affected area of Site remediated to the extent necessary to support the Work and to permit use of the Site for Companys network.

Section 11.4. Company Responsibility. Except in the case of the conditions described in Section 11.3, Company shall

SECTION 12. INVOICING AND PAYMENT

Section 12.1. Invoice and Payment
Process. Contractor shall be paid for all Work, Materials, Pass-Through Costs, Fees, Company Taxes and Mark-ups rendered pursuant to this Agreement as follows. In no event shall Contractor commence Work on a Site in the absence of a PO
authorizing such Work; and in no event shall Contractor proceed with additional Work on a Site not covered by the original PO for the Site absent written authorization from Company.

(i) By the Effective Date, Contractor shall provide an initial draft of the Rolling Cash Flow Projection (defined below) and supporting assumptions used
to arrive at the amounts shown in such draft of the Rolling Cash Flow Projection. Within ten (10) Business Days after the Effective Date, Company will wire an initial payment to Contractor in an amount based on the forecast of compensation to
be earned as described below in Sections 12.1(viii) through (xiii) and the factors described in Section 12.4 for the then current month (Month 0) and an Advance Payment (defined below) for the ensuing two months (Months 1 and 2).

Execution Copy



(ii) Following the payment of the initial Advance Payment, the process for invoicing and payments
described in Sections 12.1 (iii) through (vii) shall be followed by both Parties for the remainder of the Term.

(iii) Commencing on the 15thday of the first calendar month after the Effective Date, and by the 15thday of each month thereafter, the Parties
shall hold a meeting (Compensation Projection Meeting) attended by Authorized Representatives of the Parties to review and agree upon the projected compensation to be earned by Contractor for each of the ensuing 18 months
(Months 1  18, with the month containing the Compensation Projection Meeting designated as Month 0 in each monthly revision). The projected compensation (Rolling Cash Flow Projection) will be
based on the then-current Throughput Model and forecast compensation to be earned as described below in Sections 12.1(viii) through (xiii) and the factors described in Section 12.4. If the Rolling Cash Flow Projection forecasts no
compensation for the Construction Start Payment Milestone (as defined in Exhibit F) occurring in Months 0 through 2, the amount of the Advance Payment payable by Company to Contractor by the end of Month 0 shall be equal to the projected
Contractors compensation for Month 2. If the Rolling Cash Flow Projection for the first time forecasts compensation for the Construction Start Payment Milestone (as defined in Exhibit F) occurring in Months 0 through 2, the amount of
the Advance Payment payable by Company to Contractor by the end of Month 0 shall be equal to the projected Contractors compensation for Months 2 and 3. All subsequent Advance Payment amounts shall be equal to the projected Contractors
compensation for Month 3 for the then-current Rolling Cash Flow Projection. The Parties agreement on the Rolling Cash Flow Projection will also represent agreement by the Parties on the Advance Payment amount. If the 15thday of a month falls on a day that is not a Business Day, then the Parties shall meet on a Business Day prior to the 15th.

(iv) At the Compensation Projection Meeting, Contractor shall provide to Company supporting assumptions used to arrive at the amounts shown in the Rolling Cash Flow Projection. Company may also elect at such meeting to delay the month
during which the first Construction Start Payment Milestone is scheduled to occur to a later month so long as such milestone is not then-currently projected to occur earlier than Month 2 at the time of such election. If these assumptions change as a
result of the Compensation Projection Meeting, Contractor shall provide a revised Rolling Cash Flow Projection by no later than the 20thday of
Month 0, as a prerequisite to the Advance Payment due by the end of Month 0; provided, however, that Contractor shall have no obligation to proceed with the applicable Work absent agreement on the Advance Payment. Should the Company fail to
meet with Contractor by the 15thday of any month, or fail to agree as to the amount of the Advance Payment, for any reason, the Advance Payment for
the prescribed period shall be based on the most recent agreed Rolling Cash Flow Projection provided by Contractor to Company.

(v) Except
for the initial Advance Payment to be made within the time period specified in Section 12.1(i), by no later than the last Business Day of Month 0, Company shall make a wire transfer of the Advance Payment.

(vi) By the 5thday of Month 1, Contractor shall issue a reconciliation invoice (Reconciliation Invoice) which includes detail of the actual
compensation earned by the Contractor (as described below in Sections 12.1(viii) through (xiii)) through the end of Month 0, in accordance with the requirements and in substantially the same form as the examples set forth in Exhibit D. Any
difference (True-up) between the amounts paid by Company through the end of Month 0 and the actual compensation earned by Contractor through the end of Month 0 due to Company may, at Companys election, be set off from
any future Advance Payment or Reconciliation Invoice. If Company does not elect to set off all or any portion of such True-up amount against a future Advance Payment or Reconciliation Invoice, then upon written request from Company, Contractor shall
pay such True-up amount, or such portion thereof that has not been set off, to Company within thirty (30) days of such written request. Any True-up due to Contractor will be paid by Company by the last Business Day of Month 1 consistent with
Section 12.1(v). By way of example, on March 5th, a Reconciliation Invoice will be issued detailing actual compensation earned through
February. Any True-up due to Company will be set off from the Advance Payment made by March 31st. Any True-up due to Contractor will be paid by
the Company no later than March 31stconsistent with Section 12.1(v).

(vii) Reconciliation Invoices shall meet the following requirements:

(a) Each line item on the Reconciliation Invoice shall be specific to one and only one PO, unless otherwise mutually agreed by the Parties.

(b) Each separate item (e.g., Milestone, Pass Through Cost, Materials charge, Materials Mark-up fee, Company Taxes, Management Service Fee, charges for
Supplemental Unit Prices, PMO charges) shall be listed on a separate line on the Reconciliation Invoice. Line items shall not bundle charges together (e.g., Materials and services), except in the case of miscellaneous Materials with values under
$100 or unless otherwise mutually agreed by the Parties.

(c) Each Reconciliation Invoice will be substantially in the form of
Attachment 1 to Exhibit D.

(viii) Compensation for PMO Services Personnel Costs, business travel costs and Company Taxes directly
related to business travel costs as described in Exhibit F is earned on a monthly basis.

(ix) Compensation for Base Cell Site
Unit Prices, as described in Exhibit F in accordance with the amounts and percentages assigned to each Site Milestone as set forth in Exhibit F (Site Milestone Payment Schedule), is earned as each such
Milestone is achieved. The percentages shall be applied to the Base Cell Site Unit Prices for each Site, pursuant to a PO. Compensation for Changes is earned as provided in each agreed Change Order. If the Change Order applies to a task or
Deliverable included under the Base Cell Site Unit Price, then compensation for the

Change shall be earned proportionally according to the same percentages assigned to each Site Milestone as set forth in Exhibit F, but will be
invoiced on a separate line item, as illustrated in Exhibit D. By way of example, if the construction of a Structural Modification is conducted concurrently with construction of the Site, and is included in the PO for Construction of that
Site, compensation for the construction will be earned as follows: [***]% at Construction Start Milestone, [***]% at Construction Complete Milestone, and [***]% at Site Acceptance Milestone.

(x) Compensation for Materials and Mark-Up as described in Exhibit F is earned as invoices are received from Contractors material
suppliers.

(xi) Compensation for Pass-Through Costs as described in Exhibit Fis earned when such costs are invoiced to or paid by
the Contractor.

(xii) Compensation for Company Taxes as described in Section 13 of the Agreement and Exhibit F is earned when
the compensation for the respective line items to which the Company Taxes apply are due.

(xiii) Compensation for the Management Service
Fee is earned as described in Exhibit F.

All Reconciliation Invoices shall be submitted to:

TerreStar Networks

12010 Sunset Hills Road

Sixth Floor

Reston, Virginia 20190

Attn: Accounts Payable (or such other location as Company may direct Contractor)

Upon request, Contractor shall also
provide any additional information that Company may require to confirm the accuracy of Contractors Reconciliation Invoice calculations. Contractor acknowledges that, for purposes of Companys payment processing system, the amount invoiced
on each Reconciliation Invoice must not exceed the amount authorized by the corresponding PO(s) issued by Company for the Work to which the Reconciliation Invoice relates, as adjusted pursuant to Section 23. Contractor shall use all reasonable
efforts to obtain prior approval from an Authorized Representative of the Company for the submission of any Reconciliation Invoice that exceeds the corresponding PO(s), as such PO(s) may be adjusted pursuant to Section 23. In the event
Contractor fails to obtain such prior approval from an Authorized Representative of the Company and proceeds to submit a Reconciliation Invoice, Company shall, subject to Section 12.2, return such Reconciliation Invoice for correction by
Contractor.

Section 12.2. Payment Instructions. Company shall pay all undisputed amounts in accordance
with the terms herein. No payment shall constitute an acceptance of any Work that is not in accordance with this Agreement or any Applicable

Any disagreement concerning payment on a
Reconciliation Invoice shall be resolved in accordance with Section 26 hereof. Contractor shall not invoice Company for Milestones not achieved or Work not completed as a result of an Excusable Delay; provided, however, that the occurrence of
an Excusable Delay shall not excuse the payment of any Reconciliation Invoices which are due and owing for Work properly performed prior to or during the Excusable Delay or any Advance Payment due and owing in accordance with the Rolling Cash Flow
Projection, which shall be modified as necessary to take into account any projected adjustment of Work resulting from an Excusable Delay. The final payment due under any PO, shall be due and payable thirty (30) calendar days following the last
to occur of the following: (i) the Work has been completed in accordance with the terms of this Agreement; (ii) Contractor has delivered a Reconciliation Invoice for Final Payment (including all details and supporting documentation as to
amounts invoiced) and (iii) Contractor has delivered to Company any required lien waivers of all relevant subcontractors confirming that they have been fully paid for the Work, together with any other Deliverables necessary to meet the
applicable PO. Final Payment means the last Reconciliation Invoice that Contractor is entitled to submit with respect to a PO. Acceptance by Contractor of Final Payment for Work covered by a PO shall be irrevocably deemed
to be Contractors acknowledgement that it has been paid in full under the PO and shall constitute a waiver of all claims for payment by Contractor in respect of such Work, except for (i) any claims made in writing prior to the delivery of
the Reconciliation Invoice for Final Payment and identified as unsettled and (ii) expenses for Materials or Pass-Through Costs that are either inadvertently omitted or not reasonably available to Contractor at the time of the Reconciliation
Invoice for Final Payment or additional Company Taxes which in any event must be submitted within twelve (12) months of the Reconciliation Invoice for Final Payment as to the applicable PO or such amount(s) shall be deemed waived by Contractor.

If Contractor shall not have delivered any properly prepared Reconciliation Invoice as required hereunder within the time specified therefore, the
relevant payment due date shall be extended on a day for day basis after receipt of such properly submitted Reconciliation Invoice. If Company disputes any portion of a Reconciliation Invoice as failing to satisfy any of the foregoing requirements
or as incorrect, Company will make timely payment of the undisputed amounts.

Company reserves the right to raise payment disputes for up to twelve (12) months after the applicable payment
due date. After such period, Company may raise payment disputes solely through the audit process described in Section 14.2.

Section 12.3. Late Payment. Any amounts due either Party under this Agreement that are not subject to a dispute and remaining unpaid after the due date shall accrue interest, commencing on the day after the
due date and compounded for each day thereafter until the date paid, at the rate equal to [***] percent ([***]%) above the prime lending rate quoted to substantial and responsible commercial borrowers on ninety (90) day loans by the Morgan
Guarantee Trust Company, New York, on each day such interest accrues.

Section 12.4. Cash Flow Projection.
The Parties agree that the Rolling Cash Flow Projections are to be based on good faith estimates of compensation projected to be earned by Contractor as described herein. Calculations of projections to be presented, discussed, and agreed as
described above will be based upon the following factors:

(i) Number of Sites/Search Rings projected to reach each payment Milestone during
the relevant months, per the then current version of the Throughput Model.

(ii) Projected ratio of Site types by Milestone, by month. This
projection should be based on factors such as past experience, projected locations (i.e., predominately urban, rural, suburban), trends in availability of various Site types, and shall be adjusted in future projections to reflect additional
experience in the markets.

(iii) Projected amount of compensation for services that are not covered under the Base Cell Site Unit Price,
such as structural modification design and construction required to make any Company-approved modification, stealthing, landscaping, and services subject to Supplemental Unit Costs as set forth in Exhibit F, Attachment 5.

(iv) Projected amounts for Materials. This should be based on standard assumptions for Materials based on Site type, percentages of Sites requiring
stealthing and structural modifications, and other factors affecting the amount of materials required. These projections should be based on past experience and adjusted in future projections to reflect additional experience in the Markets.

(v) Projected amounts for third party fees (e.g., landlord, jurisdictional). These projections should be based on past experience and
adjusted in future projections as appropriate to reflect additional experience in the Markets.

(vi) Projected amounts of MSF, which
amounts must be tied to paragraphs (i) and (iii) of this section.

(vii) Projected amounts of Materials mark-ups, which amount must be tied to paragraph (iv) of
this section.

(viii) Projected amounts of PMO compensation

(ix) Projected amount of Company Taxes.

All of the above projected amounts shall be tied to the then
current version of the Throughput Model and Site mix assumptions.

Section 12.5. Suspension.

(i) If Company fails to make any undisputed payment when due, Company shall be considered in material breach of this Agreement and Contractor shall
have the right, following fifteen (15) days of written notice to Company, to suspend the Work in whole or in part and seek remedies in accordance with this Agreement. Within five (5) days of Contractors delivery of the foregoing
written notice, Companys and Contractors respective Management Committee representative(s) and Chief Financial Officer(s) shall meet and discuss the underlying causes of the breach, alternatives to Contractors suspension of Work,
steps that may be taken by Company to remedy the non-payment to prevent suspension, and steps by Contractor to minimize any costs that Contractor may incur if the Work is suspended in whole or in part (such meeting is referred to herein as the
Pre-Suspension Meeting). If Company fails to meet with Contractor within five (5) days of Contractors notice or if the Parties cannot reach an agreement by the end of the fifteen (15) day notice period for
any reason, then Contractor may exercise the rights set forth in this Section 12.5. Further, upon Companys written request at any time during the 15 day notice period, Contractor shall suspend the Work in whole or in part. In the event of
a suspension under this Section, the provisions of Section 10.4 shall apply as to any ongoing and reasonable costs actually incurred by Contractor.

(ii) In the event Company cures the breach (i.e., as to past due undisputed amounts due to Contractor) within the time provided in Section 10.1(i) of this Agreement, Contractor shall immediately resume Work
unless otherwise directed by Company in writing.

Section 12.6. Material Breach. Company is not obligated
to make any payment under this Agreement for Work that is unauthorized via a mutually agreed PO, that fails to satisfy Applicable Requirements or that is otherwise completed in breach of this Agreement until such time as Contractor has cured the
breach to Companys satisfaction. No payment shall constitute an acceptance of any Work that is not in accordance with this Agreement or any Applicable Requirements. Notwithstanding the foregoing, if only a part of an Invoice is in dispute as
failing to satisfy any of the foregoing matters, Company will make timely payment of the undisputed amounts.

extent possible, the Company shall provide the Contractor with a properly completed sales tax exemption certificate for the state evidencing the Companys intent to take advantage of such exemption. If Work has started in a state prior to the
Company providing the Contractor with said exemption certificate, the Contractor shall accept the exemption certificate as of the date issued. Contractor and Company will cooperate to apply for refunds of taxes paid prior to receipt of exemption
certificates.

Contractor shall provide Company with Contractors sales tax registration number from the states in which goods and/or

will comply with the standard set forth in Section 2.4, that the Materials shall conform to the standard set forth in Section 2.6, that the
Deliverables will comply with the Applicable Requirements and that each Site will comply with all applicable Site specifications. Contractor further warrants that it will meet the production schedule in the Throughput Model and any time schedules
required by this Agreement or by any applicable PO, and will within two (2) Business Days notify Company in writing of any material actual or anticipated delays.

not to comply with the warranty standards set forth in Section 19.2, then upon written notice from Company, Contractor shall promptly perform corrective services of a type similar to the Work originally undertaken, regardless of prior
inspections or acceptance to conform with the requirements of this Agreement. Company shall give such written notice within a reasonable period after the discovery of the deficiency or defective condition. All corrective work for which Contractor is
responsible shall be undertaken by Contractor at Contractors sole expense and the unexpired part of the Warranty Period shall remain in effect as to such corrected Work following Companys acceptance of the required corrective work.
Company may accept defective or non-conforming work instead of requiring its removal and correction, upon the condition that Company shall deduct from payments to Contractor an appropriate amount for damages. Contractor shall be responsible for all
costs and expenses arising from repair, packaging, shipping, insurance, Taxes, and other matters associated with any corrective measure. In no event shall final payment, partial acceptance of total work, or partial or entire use or occupancy by
Company relieve Contractor of liability or responsibility for faulty materials or workmanship or any breach of the Agreement.

Contractor shall, however, be reimbursed any expenses incurred either in support of litigation or arbitration or to implement such repairs at Companys
request (e.g., tower climbing and removal of equipment where the supplier has furnished replacement equipment only).

notice of defect from Company, and provided the Parties have not agreed in writing upon an alternative cure, Company may, by separate contract or otherwise, make the necessary cure and Contractor shall pay to Company all the costs of such cure or,
at Companys election, Company may set-off such amounts against sums otherwise due Contractor. Company may return the Deliverables to Contractor, at Contractors expense and Companys option, for correction, replacement or credit,
even if the period to perform those corrections extends beyond the Deliverables warranty period but in no event shall the Warranty Period itself be extended.

Section 19.7. Exclusive Warranties. The warranties set forth in this Section 19 are the sole and exclusive warranties of Contractor in connection with the Work and Materials and
equipment furnished under this Agreement and Contractor hereby disclaims and Company waives any other express, implied or statutory warranties, including WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

failure of Contractor or any of Contractor Parties to comply with applicable Laws, including, but not limited to Laws related to Hazardous Materials for which Contractor is responsible under Section 11.3; (iii) any act or omission by
Contractor or any of Contractor Parties that worsens, releases, or creates any Hazardous Material for which Contractor is responsible under Section 11.3; (iv) the transport or disposal of any materials which created or would create a
Hazardous Material on or off any Site covered by the Work for which Contractor is responsible under Section 11.3; or (v) for personal injury or property damage. Company will defend, indemnify and hold harmless Contractor, Contractors
Affiliates and their respective officers, directors, employees, agents and customers (each, a Contractor Indemnitee) from and against all Damages arising out of a claim by a third party against a Contractor Indemnitee to
the extent arising from the fault or negligence of Company or a Company Party in connection with personal injury or

property damage. Each Party and each of the Company Indemnities and Contractor Indemnities shall have the right to defend its own interest in connection with
any such Claims, and such election to so defend its own interest shall in no way relieve Contractor or Company of its obligations under this Section 20.1. The duties described in this Section 20 shall survive the termination or expiration
of this Agreement for a period of three (3) years.

In the event Claims are brought against any Company Indemnitee by an employee of Contractor or of any other Contractor Party, the indemnification obligations provided in Section 20.1 shall not be limited by any limitation on the amount or type

indemnification under this Agreement (a Claim), the Party seeking indemnification shall give prompt written notice of the Claim to the Indemnitor. The notice must include a copy of any written documentation regarding the
Claim received by the Indemnitee. Upon receipt of notice of a Claim, the following provisions shall apply:

(i) The Party Indemnitor shall,
at its option, settle or defend the Claim at its sole expense and with its own counsel. Each Indemnitee will cooperate in all reasonable respects with the Indemnitor and its attorneys in the investigation, trial, and defense of the Claim and any
appeal; provided, however, that any Indemnitee may, at its own expense, participate, through its attorneys or otherwise, in such investigation, trial, and defense of such claim and any appeal arising therefrom. No settlement of a claim
that involves a remedy other than the payment of money by Contractor will be entered into without the consent of each affected Company Indemnitee, which consent will not be unreasonably withheld, conditioned or delayed.

(ii) If the Indemnitor (a) fails to notify the applicable Indemnitee of the Indemnitors intent to take any action within thirty (30) days
after receipt of a notice of a Claim for which it is responsible under this Section or this Agreement or (b) fails to proceed with the resolution of the Claim for which it is responsible, the Indemnitee, with prior written notice to the
Indemnitor and without waiving any rights to indemnification, including reimbursement of reasonable legal fees and legal costs, may defend or settle the Claim without the prior written consent of the Indemnitor. The Indemnitor will reimburse the
Indemnitee on demand for all damages, cost and expenses incurred by the Indemnitee in defending or settling the Claim.

Party) has delivered a Dispute Notice to the other Party (the Responding Party), the Management Committee shall meet and attempt to resolve the Dispute. If the Dispute is not resolved within fifteen

the confidential mediation process, in any arbitration or subsequent litigation or administrative proceeding; provided, however, that fully-initialed journal entries, and any written modifications and dispute settlement agreements
which have been fully signed by all necessary parties, may be introduced into evidence. Any judgment upon the award rendered by the arbitrator or arbitrators may be entered in any court having jurisdiction thereof. The arbitrator shall not have

Section 29.11. Entire Agreement; Order of Precedence. This
Agreement, together with all exhibits and all documents expressly referred to in this Agreement, constitutes the complete and exclusive statement of the agreement of the parties with respect to the subject matter hereof and supersedes all prior
proposals, understandings, and agreements, whether oral or written, between the parties with respect to the subject matter hereof, unless specifically mentioned herein. Contractor acknowledges that there were no representations or promises made by
Company on which Contractor has relied in entering into this Agreement that are not expressly stated herein. In case of conflict between any provisions of this Agreement, the order of precedence of the documents constituting this Agreement is as
follows, each listed document superseding in the event of any conflicting provision in a later listed document: (1) Agreement text, (2) the Exhibits; (3) the POs; and (4) any other document that makes specific reference to this
Agreement. If Contractor or Company submits Purchase Orders, Invoices or other similar documents for accounting or administrative purposes or otherwise, no pre-printed or similar terms and conditions contained in any such form will be deemed to
supersede or modify any of the terms and conditions of this Agreement.

Section 29.12. Site Security.
Contractor shall, as applicable to the Work, maintain and enforce security standards and procedures at each Site and with all applicable work-safety and other Laws. In the event Company determines that additional procedures are required to ensure
adequate security protection for the Sites and the Work, Contractor shall cooperate with Company to develop and implement such additional procedures as Company deems necessary to ensure an effective security program for protection of the Sites and
the Work. Where the Work includes construction, Contractor shall secure, protect, and be responsible for, and shall provide all necessary or desirable measures for, security and protection of each Site, the Work, and all materials, supplies, tools,
and equipment and personal property at the Site, whether or not incorporated into the Work, including, but not limited to utilizing fences, gates, or cameras, as reasonably required. Contractor exclusively shall bear the cost of, and be liable for,
all loss and damage to any of its tools, equipment, and all other personal property at a Site, except to the extent that such loss or damage is directly caused by Companys negligence or willful misconduct. Where the Work includes construction,
Contractor shall be responsible for managing all such security requirements regardless of any security arranged by any other person. Contractor shall comply with any underlying lease, license or other agreement applicable to the Site during all Work
performed.

Section 29.13. Homeland Security. In the event that any Law is instituted under The Homeland
Security Act of 2002 (H.R. 5005) or any successor Law, or any similar Homeland Security initiatives instituted under any Law or by any government agency, or in the event Company makes any changes to its current security policies reasonably
necessary to address Homeland Security concerns, Contractor agrees that, as part of the Work, it will meet or exceed within a reasonable timeframe such changes in Law or procedures, and that as part of that compliance it will adopt and implement any
specific recommendations that Company provides to Contractor.

Section 29.14. Site Access. Contractor Parties shall be permitted
access to any Work areas subject to compliance with any reasonable safety and security provisions in effect at the time of such access. Contractor shall ensure that all Contractor Parties strictly comply with Companys policies whenever
Contractor Parties are given access to such Sites.

Section 29.15. No Company Employment Liability.
Company shall have no responsibility for employment matters affecting any of the Contractor Parties, including, without limitation, compliance with applicable workers compensation, unemployment compensation, medical, dental, and disability
insurance, social security, withholding, and other Laws governing such matters. No employee of any Contractor Party shall be entitled to any medical coverage, life insurance, or participation in Companys savings plan, stock purchase plan, or
other benefits afforded to Companys regular employees or those of Companys affiliates.

Section 29.16.
Non-Solicitation of Employees. Neither Company nor Contractor shall, without the written consent of the other (it being understood that a Partys consent may only be given by an Authorized Representative), directly or indirectly
at any time during the Term (a) recruit or solicit any employee of the other Party who has devoted any substantial effort to the Work or to the administration of this Agreement, for employment or for retention as a consultant or service
provider to such Party, within a period of six (6) months after such employee ceased to be engaged in the Work or the administration of this Agreement, or (b) hire, retain or participate (with another company or third party) in the process
of hiring any such employee of the other Party or provide names or other information about such employees to any person or business under circumstances which could lead to the use of that information for purposes of recruiting or hiring;
provided, however, that the general solicitation of employment by either Party without targeting any specific employees or groups thereof from the other Party shall not be deemed a breach of this commitment. Notwithstanding the
foregoing, either Party shall be entitled to employ or retain the services of any employee terminated or otherwise separated from employment by action of the other Party, subject to Companys right to request removal of such employee from
performing work under this Agreement in accordance with the terms hereof.

Section 29.17. Good Faith
Dealings. Each Party agrees to undertake to act fairly and in good faith in relation to its exercise, performance and compliance with its respective rights and obligations under this Agreement. For the avoidance of doubt, the obligation set
forth in this Section shall not override or qualify the term for any reason as applied in Sections 12.1(iv)or 12.5.

A Search Ring is a specified geographic area within a Market comprising a part
of the radio access network (or RAN) and is designed to contain a single Company Site used in connection with the operation of the RAN. Each Search Ring will clearly define latitude and longitude of the Ring center, the
radius of the search area around the Ring, and the height (including +/- tolerance) of RAD center with respect to the applicable Site level measurement point. Contractor will utilize standard Site configuration unless noted differently in the Search
Ring information. Each Market will contain multiple Search Rings. Contractors Market Managers will coordinate with Contractors Program Management Office as necessary to ensure receipt of the Search Rings. A Search Ring is also sometimes
referred to in this Agreement as a Ring.

Preliminary research of new build Sites

For all Search Rings, Contractor will perform preliminary research to identify potential candidates, suitable buildings or other structures, and existing
towers/facilities for the pre-determined coverage areas. Contractor will first search for opportunities on existing towers (i.e., Collocation Sites), Rooftops or other structures such as Water Towers. If none of the foregoing is available,
Contractor will so advise Company and search for available space for a new build (i.e., Raw Land) Site. Contractor will analyze the pre-determined coverage area to understand the zoning laws, permitting and zoning history, and processes required to
successfully obtain permits for the Sites.

Site Candidate Information Package (SCIP) Submission, Scoring and Ranking

SCIP Submission. For each Search Ring released, Contractor will identify up to three (3) Site candidates and will
provide its analysis of each candidate, in the form of a completed Site candidate information package (each a SCIP), attached hereto as Exhibit C, Attachment 2, per candidate. In the event that three
(3) feasible candidates are not available, the Market Manager will notify Company in advance of submitting the SCIP(s) and include in the submission a detailed written explanation outlining why three (3) candidates were not available.
Company will notify Contractor within two (2) Business Days of receipt of notification if it desires further explanation as to the number of candidates, absent which the number will be deemed accepted. If Company requests, Contractor will
provide more than three SCIPs per Ring and Contractor may charge Company for each additional SCIP submitted in accordance with the terms herein at the unit price set forth in Exhibit F. Additionally, if Company determines that the search area
in which a Ring was previously released requires redesign and such redesign results in the release of new Search Ring(s), the old Search Ring will be cancelled, and the Company will issue the new Search Ring(s) as previously described. Contractor
will upload electronic versions of all completed SCIPs in Companys SMS.

Scoring, Ranking, and Guidelines. Contractor will
score the SCIPs according to leasibility, zonability, constructability, and order of magnitude (i.e., cost) on a 1-5 scale using the criteria set forth in Exhibit C, Attachment 3 hereto. Contractor will obtain scores from the backhaul and RF
design Network Vendors according to the Sites backhaul and RF characteristics, respectively. The backhaul and RF design Network Vendors will provide such data to Contractor within five (5) Business Days of Contractors input into
Companys SMS of the final SCIP for a given Search Ring. Contractor will then

consolidate the scores into a consolidated score for each Site. Then Contractor will rank the candidates by first, second, and third choice, depending on the
number of SCIPs. The Site ranked first will be Contractors primary candidate recommendation. The recommended primary candidate need not be the highest scoring candidate. However, Contractor should explain in writing why the Site was chosen as
the primary candidate in all cases. Such scoring and recommendation will be provided in the form of Exhibit C, Attachment 3 hereto. Contractor will provide a detailed explanation of its recommendation.

SCIP Milestone Payment. Contractor agrees that the SCIP Submission Milestone payment is conditioned upon Contractors submittal into
Companys SMS of such number of complete SCIPs per Ring as provided in accordance with Section 3.3.1.

Primary Candidate
Approval

After Contractor has uploaded the completed scoring and ranking forms and the primary candidate recommendation into
Companys SMS, Company will have seven (7) Business Days to approve the primary candidate in writing, upload the approval and a Site Acquisition Notice to Proceed (also referred to as the SA NTP) (attached hereto
as Exhibit C, Attachment 4), and ensure that the completed RF Site configuration sheet (in the form attached hereto as Exhibit C, Attachment 8) and backhaul Site Configuration sheet (in the form attached hereto as Exhibit C,
Attachment 9) are submitted from the responsible Network Vendors and uploaded into the SMS. Upon Companys uploading of these documents in the SMS, Contractor will have met all requirements for the Primary Candidate Approval Milestone
payment.

If Company does not notify Contractor of any deficiency or fails to upload the approval and/or the other referenced documents for
which it is responsible for uploading within the foregoing seven (7) Business Day period, the Primary Candidate Approval Milestone will be deemed complete and accepted by Company for payment purposes. With respect to any portion of the Work
that Company deems incomplete, Contractor will complete such activity and the above acceptance procedure will be repeated.

At such time
when the Site Acquisition NTP and the completed RF Site configuration sheet and backhaul Site configuration sheet are uploaded into the SMS, Contractor will commence all other acquisition activities for such Site as set forth in this Agreement,
including the activities in Section 3.5 through Section 13 of this SOW. Contractor will notify Company in writing when it has completed all Site acquisition Work and submitted all Deliverables required to achieve the Site Acquisition
Complete Milestone (such notice is referred to herein as Site Acquisition Complete Notice To Company).

Contractor
agrees that the Site Acquisition Complete Milestone payment is conditioned upon (1) Contractors provision of all completed Deliverables and completion of all tasks applicable to Site acquisition as set forth in this Section 3 through
Section 13 of this Exhibit C; (2) Companys acknowledgement of the completion of all and acceptance of all Deliverables and tasks as evidenced by a Site Acquisition acceptance letter signed by an authorized Company representative; and

Section 2: Introduction

The TerreStar Story

Who We Are

TerreStar is a satellite communications
company. We are building an IP enabled, next generation mobile communications network over an integrated satellite-terrestrial system. The

terrestrial portion of our telecommunications network is designed to supplement our satellite communications capabilities in dense urban areas, to ensure
seamless connectivity when it is needed most.

TerreStars system will operate in two 10-Mhz blocks of contiguous spectrum in the 2 GHz band
throughout the United States and Canada. The companys spectrum footprint will cover a total population of nearly 330 million. The satellite footprint is highlighted in blue, below.

LOGO

Frequencies

TerreStar has
received an allocation from the FCC for 20 MHz of spectrum in the S-Band. The S-band uplink is 2,000-2,020 MHz and downlink is 2180-2200 MHz. No cellular communications companies are currently using these frequencies, so there is minimal risk of
interference with existing tenants on most collocation sites. TerreStar has a blanket FCC license that covers the entire US, no per site license is required by the FCC.

Technology / Equipment / Footprint

TerreStars desired equipment footprint area is a modest 12 X 10
location. We anticipate using three 4 tall X 8 wide antennas for each installation. TerreStar utilizes W-CDMA base station radios, from [***], these radios will have different part numbers than CDMA equipment, and may not yet

Backhaul

TerreStar anticipates that some of the sites may not
have adequate fiber available, in which case microwave backhaul will be required for the site. Currently, we are planning to use microwave antenna models with of 1 or 2 diameters.

Section 3: Due Diligence

Contractor will perform the required due diligence on each site
prior to TerreStars approval and execution of the Lease depending on the specific leasing requirements for each site. Contractor will submit a completed Due Diligence Checklist, in the form attached hereto as Appendix 2, in each Site Lease
Package. The due diligence for each site, will include, as appropriate:

Term of Lease:

The term of Terrestars tenancy shall commence upon the start of construction of the Tenant Facilities or twelve (12) months following the Effective Date of the agreement, whichever first occurs and shall terminate on the fifth
anniversary of the Term Commencement Date unless otherwise terminated. The agreement shall automatically extend the Term for five (5) successive five (5) year on the same terms and conditions as the initial term, unless TerreStar notifies
the Landlord of its intention not to renew prior to commencement of the succeeding Renewal Term.

Termination Rights:

Lessor Termination: Lessor shall have a right to terminate the lease agreement, in the event that TerreStar fails to cure non-payment within 15 days of notice or
any other breach within 60 days of receiving notice (unless a longer cure period is agreed to); or for condemnation or casualty. Any other termination rights, must be approved by TerreStar Legal.

TerreStar Termination: TerreStar shall have a right to terminate the lease agreement, with 30 days notice to the lessor in the event that lessor fails to cure a
breach within 60 days of receiving notice (unless a longer cure period is agreed to); if TerreStar does not obtain or maintain any license, permit or other approval necessary for the construction and operation of the TerreStars Facilities; if
TerreStar is unable to occupy and utilize the Premises due to an action of the FCC, including without limitation, a take back of channels or change in frequencies; if any environmental report for the land reveals the presence of any Hazardous
Material after the Term Commencement Date; if TerreStar determines that the Premises are not appropriate for its operations for economic or technological reasons, including, without limitation, signal interference; or if the Landlord fails to
deliver to TerreStar a required executed memorandum of agreement or non-disturbance and attornment agreement . Additionally, Premises or Tenant Facilities are damaged, destroyed, condemned or transferred in lieu of condemnation, Tenant may elect to
terminate this Agreement as of the date of the damage, destruction, condemnation or transfer in lieu of condemnation by giving notice to Landlord no more than forty-five (45) days following the date of such damage, destruction, condemnation or
transfer in lieu of condemnation. If Tenant chooses not to terminate this Agreement, Rent shall be reduced or abated in proportion to the actual reduction or abatement of use of the Premises.

Execution Copy



Term and Rent Commencement:

The term of TerreStars tenancy
shall commence upon the start of construction of the Tenant Facilities or twelve (12) months following the Effective Date of the agreement, whichever first occurs. Within fifteen (15) business days following the Term Commencement Date and
on the first day of each month thereafter, Tenant shall pay to lessor the agreed upon rent. Rent for any fractional month at the beginning or at the end of the Term or Renewal Term shall be prorated.

Taxes

If personal property taxes are assessed, TerreStar shall pay
any portion of such taxes directly attributable to the TerreStars equipment on the premises. Lessor shall pay all real property taxes, assessments and deferred taxes on the land; taxes assessed on lessors operations or net income, and
pay a pro rata share of such tower operation expenses or real estate taxes.

Space to be Leased:

Tower Space: The tower space (or rooftop space) leased for the use of the antennas should match the dimensions of the antenna to be used at the site.

Ground Space (Leased Space): 12X10

The ground space
leased should be: 12X10, this provides plenty of space for TerreStars initial and any future needs (See Appendix 6). In the event 12X10 is not available, Contractor is authorized to obtain a 6X6 space (at a
minimum) for the footprint of TerreStars equipment cabinets (including applicable door swings) and adjacent equipment (power and telco/ethernet supply).

Lessors Right to Stack or Make Modifications:

TerreStar understands that at some sites ground space is limited, and the lessor may
request the right to stack equipment over TerreStars equipment. If a condition of leasing the site is to allow equipment to be stacked over TerreStars equipment, or to stack TerreStars equipment over the equipment of an existing
tenant, TerreStars Market Manager needs to be notified of such requirement during the application process and must have the right to reject the site, based on this requirement. If TerreStar proceeds with the lease for this site, TerreStar must
have the right to review plans in advance and accept or reject the proposed location of the equipment. In no event may the proposed stacking or modifications impede TerreStars RF propagation pattern. In the event that a shelter is installed
above TerreStars shelter, the landlord shall be solely responsible for all costs and expenses associated with obtaining any required permits in connection with such shelter installation, and shall ensure that such shelter installation complies
with all applicable laws.

Lessors Right to Relocate TerreStars Equipment or the Tower:

The lessor should not have the right to relocate TerreStars equipment or the tower.

Execution Copy



Reservation of structural capacity:

The lessor shall reserve
structural capacity on the tower and site for all equipment described in the lease or SLA.

TerreStars Rights to Make Modifications:

If the subject modification is entirely within leased ground space and does not involve a frequency change (from the bandwidth described in the lease) then
no consent should be required from the lessor, nor should notice to the lessor be required.

If the subject modification involves only a change in
frequency from that specified in the lease, then no consent should be required from the lessor. However, notice to the lessor may be required, and an amendment of the lease to permit the new frequency usage may be required.

If the subject modification involves a like-for-like, swap out of antenna or other tower-mounted equipment with identical equipment or different equipment
that does not materially increase tower loading, then no consent of lessor should be required. However, notice may be required to be given to the lessor and the lease may be required to be amended to permit the new equipment, (unless it is identical
in all respects to the replaced equipment).

Conditional Leases:

Ideally, TerreStar should be able to obtain fully executed leases prior to performing all due diligence and obtaining all necessary consents, if appropriate conditions precedent clauses are added. In such cases
TerreStar (or both parties) must have the right to terminate the license if the necessary approvals are not obtained by a specified time frame. Examples of such conditions precedent are zoning approval, landlord consent, and third party waiver of
ROFR.

Site Access:

TerreStar should have the right to
access the site on a 24/7/365 basis. TerreStars access rights may be subject to the terms of the ground lease, and may be non-exclusive. TERRESTAR should have a non-exclusive easement to use all parts of the site, that are not reserved
exclusively for any other entities use, for construction access, inspection, maintenance and repair access, temporary materials staging during construction and repair, and other related uses. TerreStar should not have to give notice to the lessor
before entering a site. If necessary, it is acceptable to agree to give notice (24  48 hours max.) to the lessor before TerreStar performs elevated work at a site but for no other reason.

Snow Removal:

The lessor should be obligated to keep the access way
and site sufficiently clear of snow to permit access. Possible compromises include stating that the access must be sufficient for four wheel drive vehicles, that the clearing will only be done on request, or that the clearing will only be requested
where TerreStar has a bona fide need to access the site immediately.

Zoning Approvals:

TerreStar will obtain all zoning approvals necessary to install its equipment. The imposition of special conditions to approval may be made subject to review and approval
by lessor.

Execution Copy



Representations and Warranties:

Ideally the lessor should represent
and warrant that it holds good title to the site, and that it will assure that the site and tower comply with all applicable laws and regulations. If required, TerreStar may represent and warrant that it will maintain its equipment in good condition
and will operate in accordance with all applicable law and regulation. As with all other provisions of this Leasing Guide, if Contractor has any questions about representations and warranties, Contractor should contact TerreStars legal
counsel.

Installation of Equipment:

TerreStar shall
have the right to install and modify its equipment, with no obligation to permit lessor to perform or bid on the installation work.

Close-Out
Documentation:

It is acceptable to agree that TerreStar shall provide copies of as-built drawings, building permits and other
customary close-out documentation to the lessor within thirty (30) days of completion of installation or modification of TerreStars equipment.

Subordination and Non-Disturbance Clauses:

If required, TerreStar may agree to subordinate its interest in a site to
prior and future encumbrances of the lessors interest (a subordination agreement) provided that said encumbrances must agree that TerreStarss possession will not be disturbed in the event of foreclosure so long as TerreStar is not
in default under the lease (a non-disturbance agreement).

Ground Lease Provisions:

A copy of the ground lease (if any) must be provided; it should be an exhibit to the lease. It may be redacted to delete the amount of the rent or other confidential irrelevant information. The lease should provide
that the lessor agrees to exercise all rights to renew the term of the ground lease for the duration of the lease term as may be renewed.

RF
Interference:

The lease must provide that the lessor will cause any third party to eliminate any RF interference that its (subsequently commenced) use
causes to TerreStars (previously commenced) use. TerreStar will agree not to cause RF interference with previously commenced uses at the subject site that are FCC licensed, and to cure any RF interference within seventy-two (72) hours of
notice thereof, but will not agree not to interfere with any prior or subsequent uses that are not FCC licensed.

Payment Method:

By check or electronic transmittal payable to lessor on a monthly basis.

Execution Copy



RF Exposure:

TerreStar will cooperate with the licensor and other
site users to address non-compliance with FCC RF exposure limits.

Waiver of Landlords Lien:

The lessor should waive any rights to a landlords lien so that TerreStars property is unencumbered and may be used as collateral by TerreStar.

Indemnification Clauses:

Indemnity clauses must conform to
TerreStarstandard clauses or be approved by TERRESTARs counsel.

Limitations of Liability (Waiver of Consequential Damages):

Both lessor and TerreStar should waive any right to collateral or punitive damages.

Insurance:

The insurance clauses in the lease must accurately reflecs current coverages and limits, and otherwise be acceptable. A
summary of TERRESTARs insurance will be provided.

Utilities:

Ideally the lease will represent that separately metered electricity is available at the site. TERRESTAR should not agree to pay any share of utility costs for service supplied to lessor or other carriers.

Casualty and Condemnation:

The lease should provide that the
lessor shall repair any casualty damage to the site within ninety (90) days of the date of the casualty, and rebuild the site or replace the tower within one hundred eighty (180) days of the date of the casualty in the event the tower
and/or the site is destroyed. During the repair period, the rent should abate, and TERRESTAR should be allowed, without charge, to install and operate a cell on wheels (C.O.W.), if conditions permit.

Default and Cure Periods:

The lessor must provide written notice and
fifteen(15) day cure period before delinquent payment constitutes a default. There should be no cross default provisions. Lessor must provide written notice and sixty (60) day cure period (with additional time provided if reasonably needed and
if the cure is commenced within said sixty(60) day period) before non-monetary breach constitutes a default

Environmental Provisions:

Ideally, the lease should require the lessor to provide to TerreStar copies of any Phase 1 ESA report that it possesses. The lease should provide that the lessor shall
indemnify TerreStar against any liability or cost incurred due to environmental problems at the site unless caused by TerreStar or third parties not under the lessors control.

Execution Copy



FCC Antenna Structure Registration:

The lease should state that the
lessor shall provide a copy of the licensors FCC Form 854-R.

Governing Law, Jurisdiction:

The lease should provide that disputes will be litigated in the state where the site is located and that states law should be applied to determine the outcome.

Assignment Rights:

TerreStar must have the right to
assign its interests in the lease to third parties without the consent of the lessor, at least with respect to transfers to its parent, subsidiaries, affiliates or successors of TerreStars business whether by merger, sale of assets or
otherwise. Ideally TerreStar should be released from further liability upon making the assignment. This right should not be limited to affiliates of or successors to TerreStar. It is permissible to require notice of such assignments to be given to
lessor.

Non-Disclosure Provisions:

The lease should
provide that its content and existence should be kept confidential by both parties, with certain exceptions.

Compliance with Laws and Regulations

TerreStars operations are subject to more regulations than other cellular carriers. The satellite portion of TerreStars business brings State
Department and Defense Department rules to bear on its operations. As a result, TerreStar requires that lessors agree to not only keep the site in conformance with all applicable, laws, rules and regulations and agree to reasonably cooperate with
TerreStar regarding any compliance required by the TerreStar in respect to its use of the site. Lessor must also acknowledge that any products, software, and technical information provided under the lease are subject to U.S. export laws and
regulations and any use or transfer of such products, software, and technical information must be authorized under those regulations. Lessor must agree that it will not use, distribute, transfer, or transmit the products, software, or technical
information (even if incorporated into other products) except in compliance with U.S. export regulations. TerreStar will agree to use the site as may be required or as permitted by applicable laws, rules and regulations, and to comply with U.S.
export regulations, as well.

EXHIBIT D

ORDERING AND INVOICING PROCESSES



|I. | Introduction
|-- | ------------

This Exhibit sets forth the processes and protocols
associated with Companys issuance of Purchase Orders and Contractors invoicing for the Work covered in the Agreement.



|II. | Purchase Orders and Change Orders
|--- | ---------------------------------

A. In no event shall Contractor
commence Work in the absence of a PO authorizing such Work; and in no event shall Contractor proceed with additional Work not covered by the original PO absent written authorization from Company pursuant to Section 23 of the Agreement. Such
written authorization must describe the additional Work and the amount and terms of the compensation to be earned by Contractor for the additional Work.

B. Notwithstanding Section II.A of this Exhibit D, a change order (Change Order) will be issued by Company for additional Work pursuant to an agreed change request (Change Request), but is not required for the Work
to proceed if Company has provided written authorization to Contractor in another form (e.g., email). The purpose of the Change Order is to formally change the amount and scope of the applicable PO, pursuant to the Change Request, to allow for the
payment of invoices for the additional Work.

The Change Request, which will be substantially in the form of Exhibit K, must describe the additional Work
and the change in the PO amount consistent with any prior written authorization, and must be signed by Authorized Representatives of both parties. A Change Order can change the amount and scope of one and only one PO. Multiple Change Orders may be
issued for each PO during the Term.

In the event that the additional Work proceeds under written authorization (e.g., email) prior to the creation and
approval of a Change Request, then as soon as possible after the written authorization is received by Contractor, and prior to Contractors submitting a Reconciliation Invoice for the applicable Work, a complete Change Request form, consistent
with the written authorization, must be created and signed by an Authorized Representative of the Contractor. Approval of such Change Request and issuance of the Change Order will not be unreasonably withheld by Company.

C. In addition, (i) for Contractor to begin Site acquisition Work for any Site, Company must have issued a Site Acquisition Notice to Proceed for such Site and
(ii) for Contractor to begin construction Work for any Site, Company must have issued a Notice to Proceed with Construction.

|Site Acquisition and Construction                                              |  | Issued for each Site after Primary Candidate Identification and prior to Site Acquisition NTP.  Covers all Work and Materials (and associated Base Cell Site Unit Prices, Pass-Through Costs, Company
Taxes, Mark-ups, and MSF) for a Site from Site Acquisition NTP to Construction Complete.  The PO amount will be based on Base Cell Site Unit Prices for the Site type and Market for the Site, as well as standard assumptions for Materials, Pass-Through Costs, Mark-ups, MSF, and other items per Exhibit F.  Materials for construction of a Site are to be ordered only after Company issues a Notice to Proceed
with Construction for the Site and as close as possible to the actual time of need for construction. However, Materials may be ordered prior to the issuance of the Notice to Proceed with Construction, subject to written authorization by Company.  As the costs estimates are further refined at the end of the Site Acquisition process,
this PO may be revised through the Change Order process, if required to ensure that the PO contains enough funds to cover Contractor charges through the Construction Complete Milestone. This PO must contain the Site ID.

|Special Materials Order |  | Issued as necessary and only in instances where, subject to Company approval, certain items (e.g., antennas) are ordered in large quantities and e arlier than Contractor would otherwise order them under a just-in-time ordering and delivery approach (e.g., to benefit from vendor volume
discounts).  Covers estimated Materials charges and associated
Mark-up.

|2. | SLA Measurement
|-- | ---------------

For each Market, at the end of each three (3) month
period during the Term (each referred to herein as a Measurement Period), Contractor shall report to Company the results of its performance for each Service Metric set forth below against the corresponding Service Levels. Contractor must
record any exceptions to a Service Level granted by Company and the version of the Throughput Model on which Contractor has based its Service Level calculation in, without limitation, the Service Level Tracking and Reporting instruments set forth in
this Exhibit E.

Such reporting shall be in the form of the reports set forth in this Exhibit E. For purposes of this SLA, the first Measurement Period
begins on the first day of Month 1. Month 1 begins December 1, 2007.

If Contractor fails to satisfy any Service Level two (2) or more
consecutive times, such failure shall be deemed either an Event of Release from Exclusivity or an Event of Termination for Good Cause, depending on which Service Level as detailed in Section 3 of this Exhibit. In an Event of Release from
Exclusivity, Company may use other contractors to perform the services covered by the relevant SLA in the Market where the failure occurred. In the event of Termination for Good Cause, Company may, in its sole discretion, terminate, immediately upon
written notice to Contractor, all or a portion of the Work under this Agreement, without any penalty, as follows: (1) if the relevant SLA is either SLA Numbers 1, 2 or 3 as described in this Exhibit, Company may terminate all or a portion of
the work from Ring Release to Site Acquisition Complete Milestone; or (2) if the relevant SLA is SLA Number 4 as described in this Exhibit, Company may terminate all or a portion of the Work from Construction Notice to Proceed to Site
Acceptance. Underperformance in any Market and better than expected performance in any Market shall be netted in determining the basis of Termination for Good Cause such that, as measured as a whole for the Measurement Period, if the SLA has been
satisfied no basis for Termination for Good Cause shall exist even if an Event of Release from Exclusivity has occurred in a Market entitling Company to utilize other contractors in that Market. Netting of performance shall be calculated by dividing
actual performance for the service being measured across all Markets by targeted performance across all Markets, as set forth in the Throughput Model, for each Measurement Period. In any event of Termination for Good Cause, the Companys sole
and exclusive remedy shall be $[***] for each missed SLA upon which the Termination for Good Cause is based, up to a maximum of $[***].

If Contractor
fails to satisfy any Service Level for any given Measurement Period, Contractor shall develop a work plan that (1) details the ways in which Contractor will remedy performance deficiencies and avoid repeat failures, (2) specifies a
proposed course of action to make up for its underperformance in the applicable Measurement Period, and (3) provides a new proposed Throughput Model to reflect the impact of the Service Level failure in the affected Measurement Period on
downstream Milestone targets in the Throughput Model. Contractor shall provide such plan within seven (7) days after the end of the affected Measurement Period. All changes to the Throughput Model shall be subject to Companys prior
written approval, not be unreasonably withheld or delayed.

The Companys Site Management System (SMS) will be the system of record for recording the
start and stop times for all Milestones.

|SLA 1. Total Number of SCIP Submission Milestones reached by Contractor  A metric targeting the timeliness of Contractor performance relative to providing to Company
complete SCIPs. For purposes of this metric, completion of the SCIP Submission Milestone is defined as Contractors submittal to Company of the completed SCIPs as set forth in Section 3.3.1 of Exhibit C to the Agreement. |  | Contractor will guarantee that, by the end of each Measurement Period, at least [***] percent ([***]%) of the total number of SCIP Submission
Milestones required during such Measurement Period are reached, as set forth in the then current Throughput Model (the Throughput Model) under Search Ring SCIP Submission Milestone.  If less than [***] percent ([***]%) of SCIP Submission Milestones are reached in each of two
consecutive quarters, then an Event of Release from Exclusivity shall be deemed to have occurred.  If less than [***] percent ([***]%) of SCIP Milestones are reached in each of two consecutive quarters, then an Event of Termination for Good Cause shall be deemed to have occurred. |  | If a Ring contains a Site which Contractor believes is likely to be a primary candidate, yet confirmation of the Sites availability and
suitability will be materially delayed, AND such delay results in a material change to the Throughput Model then, subject to Companys prior written approval, which shall not be unreasonably withheld, and after written request from Contractor,
the Ring will be designated as a Difficult Ring and will not be counted toward this SLA calculation.  Events resulting in a Difficult Ring may include, as applicable, unusual jurisdictional or landlord related issues, the occurrence of events set forth in Section 23 of the Agreement or changes in the assumptions set
forth in Section 4 below to this Exhibit E.  Following written request from Contractor
to designate a Ring as a Difficult Ring, Company will either (a) accept a reduced Service Level for the Measurement Period in which the Difficult Ring has been identified, (b) request Contractor to revise the Throughput Model solely to
reflect reasonably required adjustments for the affected Measurement Period(s) and then measure Contractors performance based on the revised Throughput Model, or (c) both of the activities in clause (a) and (b). All such revisions shall be
subject to Companys prior written approval, which shall not be unreasonably withheld.

|SLA 2. Turnaround Time for Primary Site Candidate Scoring and Recommendations.  A metric targeting the timeliness of Contractor performance relative to recommending to Company,
based on ranking and scoring process, a suitable candidate for a wireless facility that meets all necessary threshold requirements for the construction of a Site, including requirements pertaining to RF criteria, availability for backhaul, and
factors related to leasing, zoning, and construction (cost and time). For purposes of this metric, completion of Primary Site Candidate Scoring and Recommendations is defined as Contractors submittal to Company of the ranking documentation set
forth in Section 3.3.2 of Exhibit C to the Agreement. |  | Contractor guarantees that at least [***] percent ([***]%) of Primary Site Candidate Scoring and Recommendations in any Measurement Period will be
completed within eight (8) Business Days of submission of the required number of SCIPs for each Search Ring (e.g., if three SCIPS are required for a Ring, the eight (8) Business Days will commence when the third SCIP is uploaded into Companys
SMS; if two SCIPs are required, the eight (8) Business Day period will commence when the second SCIP is uploaded). The end of the eight day period for any Ring will be recorded when the scoring and recommendation form is uploaded into
SMS.  In the event that this [***] percent ([***]%) SLA is not reached in any two
consecutive quarters, an Event of Release from Exclusivity shall have occurred.  In the
event that less than [***] percent ([***]%) of Primary Candidate Scoring and Recommendations are not performed within eight (8) Business Days in any two consecutive Measurement Periods, then an Event of Termination for Good Cause shall be deemed to
have occurred. |  | Where Contractor can show that a Network Vendor did not complete its scoring properly on time and such delay caused Contractors Primary
Candidate Scoring and Recommendation to be delayed beyond eight (8) Business Days, then that Ring/Site shall not be counted as a miss against this SLA.  Additional events that may result in adjustment to the timing may include, as applicable, the occurrence of events set forth in Section 23 of the Agreement or changes in
the assumptions set forth in Section 4 below to this Exhibit E.

|SLA 3. Total Number of Sites for which Contractor has reached Site Acquisition Complete Milestone  A metric targeting the timeliness of Contractor performance relative to the execution and completion
of all Site acquisition activities for a particular Site. For purposes of this metric, completion of Site Acquisition is defined as Contractors submittal to Company of the documentation applicable to the Site Acquisition Complete Milestone as
set forth in Sections 3.5 through 13 of Exhibit C to the Agreement. |  | Contractor guarantees that, by the end of each Measurement Period, at least [***] percent ([***]%) of the total number of Site Acquisition
Milestones, as defined herein, required during such Measurement Period will be reached, as set forth in the then current Throughput Model under Site Acq. Complete.  In the event that less than [***] percent ([***]%) of Site Acquisition Milestones are reached in
each of any two consecutive measurement periods, an Event of Release from shall be deemed to have occurred.  In the event that less than [***] percent ([***]%) of Site Acquisition Milestones are reached in any two consecutive measurement periods, an Event of Termination for Good Cause shall be deemed to have
occurred. |  | The Parties agree that following Companys issuance of a Notice to Proceed with Site Acquisition, certain Sites may be deemed to be
Difficult to Acquire. The criteria for designating a Site as Difficult To Acquire is a Site that is difficult to acquire due to circumstances beyond Contractor or Company reasonable control (e.g., where governmental approvals
are expected but are delayed, or zoning approvals are delayed) that were not otherwise earlier ascertainable in Contractors Site selection process. Additional events that may, as applicable, result in a Site as Difficult To Acquire may include
unusual jurisdictional or landlord related issues, the occurrence of events set forth in Section 23 of the Agreement or changes in the assumptions set forth in Section 4 below to this Exhibit E.  Contractor must provide to Company written notice of Sites it deems as Difficult To
Acquire within a reasonable amount of time after identifying potential problems and delays, along with a detailed explanation of the foregoing.  Following such notice, Company will either (a) accept a reduced Service Level for the Measurement Period in which the Difficult To Acquire Site has been identified, (b)
request Contractor to revise the Throughput Model solely to reflect reasonably required adjustments for the affected Measurement Period(s) and then measure Contractors performance based on the revised Throughput Model, or (c) both of the
activities in clause (a) and (b). All such revisions shall be subject to Companys prior written approval, which shall not be unreasonably withheld.

|SLA 4. Total Number of Sites for which Contractor has completed the Ready to Set Equipment Milestone  A metric targeting the timeliness of Contractor performance relative to the execution and completion
of all construction activities for a particular Site. For purposes of this metric, completion of Ready to Set Equipment Milestone is defined as Contractors fulfillment of all Ready to Set requirements as set forth in Section 15.1 of Exhibit C
to the Agreement. |  | Contractor guarantees that, by the end of each Measurement Period, at least [***] percent ([***]%) of the total number of Ready to Set Equipment.
Milestones required during such Measurement Period are reached.  In the event that less
than [***] percent ([***]%) of targeted Ready to Set Equipment Milestones are reached in any two consecutive quarters, an event of Release from Exclusivity shall be deemed to have occurred.  In the event that less than [***] percent ([***]%) of targeted Ready to Set Equipment Milestones are
reached in any two consecutive quarters, and event of Termination for Good Cause shall be deemed to have occurred. |  | Events resulting in an adjustment to the Ready to Set Equipment Milestones may include but are not limited to, as applicable, jurisdictional or landlord issues, or public utility delays, or the
occurrence of events set forth in Section 23 of the Agreement, or changes in the assumptions set forth in Section 4 below to this Exhibit E.



|4. | Assumptions
|-- | -----------

During the Term, the factors set forth below shall form the
basis for the Throughput Model. To the extent the factors materially change, the Throughput Model shall be adjusted subject to written approval by Company, which shall not be unreasonably withheld. To effect a change to the Throughput Model,
Contractor shall submit a written request to Company stating the reason for the change along with supporting documentation and a draft of the new Throughput Model that would result from the change. Company will review the request and either approve
or deny the request for the change in writing. To the extent that the change requires any changes in PO amounts, a change request must be initiated by Contractor in accordance to Section 23 of the Agreement.

Factors that may form the basis of changes to the Throughput Model and the Rolling Cash Flow Projection are:



| |  |  | Timing of the issuance of Search Rings and additional Search Rings beyond the Search Rings assumed in the initial Throughput Model
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------



| |  |  | Site type ratios
| | - |  | ----------------



| |  |  | More than 10 percent of Search Rings redesigned due to reasons other than Contractors deficient performance
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | Completion by Company and Network Vendor of respective areas of responsibility within the timeframes necessary to support the Throughput Model, particularly SCIP
ranking, RF and Backhaul Configuration Sheets, Site Acquisition NTP, Construction NTP, and PO Issuance
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Force Majeure events/Excusable Delay
| | - |  | ------------------------------------



| |  |  | Changes in build schedules and plans on the part of Company

(1) Already known to or otherwise in the possession of the Receiving Party without any
confidentiality obligation at the time of receipt from the Furnishing Party; or

2. Confidentiality:

(a) For a period of three (3) years from
the date of disclosure (or such longer period as may be required by applicable law), all Confidential Information shall be maintained in confidence by the Receiving Party, which shall use the same degree of care, but no less than a reasonable degree
of care, in handling and safeguarding Confidential Information that it uses in handling and safeguarding its own confidential information. Except as provided in this Non-Disclosure Agreement, the Receiving Party shall not use, or disclose in any
manner to any third party, Confidential Information without the prior express written consent of the Furnishing Party.

(b) Access to and use of

this Non-Disclosure Agreement or the agreement, if any, in connection with which the Parties have entered into this Non-Disclosure Agreement and (2) are subject to a non-disclosure or confidentiality agreement no less stringent than this
Non-Disclosure Agreement. The Receiving Party shall inform such persons of the confidential nature of the Confidential Information and shall provide the Furnishing Party upon request with copies of the non-disclosure agreements entered into by the
Receiving Partys employees and/or consultants. The Receiving Party shall be responsible and liable for any breach of this Agreement by any of its representatives.

(c) If a court or administrative body of competent jurisdiction or a government agency requires the disclosure of Confidential Information, to the extent legally permitted to do so, the Receiving Party shall promptly
notify the Furnishing Party prior to disclosing Confidential Information and shall cooperate with the Furnishing Party if the Furnishing Party elects to legally contest, request confidential treatment, or otherwise avoid such disclosure.

Receiving Party shall, to the extent practicable under the circumstances, provide the Furnishing Party with written notice thereof so that the Furnishing Party may seek a protective order or other appropriate remedy, or to allow the Furnishing 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
Furnishing Party (at the Furnishing Partys expense) to obtain proprietary treatment for any Confidential Information being disclosed.

3. No

Furnishing Party, or use any patent, trademark, copyright, mask work protection right, or any other intellectual property right, now or hereafter owned or controlled by the Furnishing Party. None of the Confidential Information which may be
disclosed or exchanged by the Parties shall constitute any representation, warranty, assurance, guarantee or inducement of any kind by either party to the other, and, in particular, with respect to the non-infringement of patents, trademarks,
copyrights, mask work protection rights or any other intellectual property rights, or other rights of third persons or of either party. Confidential Information is delivered AS IS, and all representations and warranties, express or
implied,

including fitness for a particular purpose, merchantability, and noninfringement, are hereby disclaimed. Confidential Information may be modified by the
Furnishing Party at any time without notice to the Receiving Party.

4. No further obligation: Nothing in this Non-Disclosure Agreement shall
obligate either Party to enter into any further agreement or negotiation with the other, or to refrain from entering into any further agreement or negotiation with any third party, provided that such further agreement or negotiation does not result
in a violation of the provisions of this Non-disclosure Agreement.

5. Return of Confidential Information: All Confidential Information disclosed
pursuant to this Non-Disclosure Agreement, including any copies thereof, shall remain the property of the Furnishing Party and is loaned to the Receiving Party for use solely in connection with this Non-Disclosure Agreement or other arrangement in
connection with which this Non-Disclosure Agreement has been entered into by the Parties. Within fifteen (15) days of written request by the Furnishing Party, the Receiving Party shall, at the Furnishing Partys sole discretion, either

Party is not obligated within the 15 day timeframe to destroy Confidential Information that is stored on system-wide backup data storage devices until all of the data on those storage devices is destroyed or deleted in the normal course of business,

Furnishing Party written certification of compliance therewith within 15 days of such written request.

and damage to the non-breaching Party. The Parties hereby expressly agree that the non-breaching Party shall be entitled to seek the remedies of injunction, specific performance, and other equitable relief to prevent a breach of any provision of
this Non-Disclosure Agreement. The provisions of this section 8 shall not be construed, however, as a waiver of any other rights that a Party may have for damages or other relief as set forth in the Master Services Agreement dated of even date
herewith (the Master Services Agreement) which in all respects governs the Parties rights and obligations hereunder.

9. Termination:
This Non-Disclosure Agreement will terminate effective upon the expiration or earlier termination of the Master Services Agreement. Upon termination of this Non-Disclosure Agreement, the provisions of this Non-Disclosure Agreement shall remain in
effect with respect to all Confidential Information disclosed or received prior to such effective date.

10. Assignment: This Non-Disclosure
Agreement may not be assigned by either Party without the advance written consent of the other, provided however, that either Party may assign this Non-Disclosure Agreement, without consent, to an entity that acquires all or substantially all of the
assets or capital stock of the assigning Party, whether by way of merger, consolidation, or otherwise. This Non-Disclosure Agreement shall be binding upon the Parties and upon their respective legal representatives, successors and permitted assigns.

EXHIBIT I

NETWORK VENDOR CHARGES



|1. | Introduction
|-- | ------------

Contractor acknowledges that Company may incur certain
charges from Network Vendors in the event that certain Contractor obligations related to the timely completion of Site development tasks are not met (Network Vendor Charges). Where such charges are incurred due to fault of Contractor, as described
herein, Contractor shall pay Company the Network Vendor Charges actually incurred subject to the limitations in this Exhibit I.

Relationship to Service
Level Agreements in Exhibit E:

The Service Level Agreements (SLAs) in Exhibit E define the conditions for Release from Exclusivity and Termination for Good
Cause, and set liquidated damages to cover costs for Contractors failure to complete Work in accordance with the schedule set forth in this Agreement, but do not cover costs that Company incurs from Network Vendors. The liquidated damages
payable under Exhibit E do not cover and are separate and in addition to and Network Vendor Charges to be paid pursuant to this Exhibit I.



|2. | Limitations
|-- | -----------

During the Term, Network Vendor Charges may not exceed $[***]
per Site and $[***] in the aggregate. It is understood that Company may not have entered into all its Network Vendor contracts at the time of entering into this Agreement and the Parties agree that any additional Network Vendor Charges included in
the below stated categories, if any, shall likewise be subject the aggregate limits set forth herein.



|3. | Network Vendor Charges
|-- | ----------------------



| | 3.1 | Network Vendor Charges include the following: Failed Site Visit Charge
| | --- | ----------------------------------------------------------------------

A Network Vendor Charge for a Failed Site Visit shall be payable by Contractor if:

(i)



| | (a) | The Network Vendor visits a RAN Site for the purpose of installing equipment, specifically a Base Transceiver Station (BTS), a Battery Backup Unit (BBU), and/or Backhaul equipment;
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | The installation visit was scheduled using a properly completed Ready to Set form;
| | --- | ----------------------------------------------------------------------------------



| | (c) | The installation is unable to be performed either because the Site is not ready for installation, or because access to the Site is unavailable; and
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------



| | (d) | A Network Vendor charges Company for the Failed Site Visit,
| | --- | -----------------------------------------------------------

or:



|                                 |  |       |  |

| | (ii) | A scheduled visit is cancelled or postponed by Contractor less than 72 hours before the scheduled visit and the Network Vendor charges Company for the Failed Site Visit. The Failed
Site Visit Charge is subject to the $[***] per Site cap.
| | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

3.2 RF Design Standby Charge

This charge (the RF Design Standby Fee) is as follows. If the actual number of SCIP Submittal Milestones in any given month is less than
[***]% of target, as set forth in the Throughput Model, a Network Vendor Charge not to exceed $[***] per Site reflecting an RF Design Standby Charge will be charged; provided that the Network Vendor charges Company. This charge will be calculated by
subtracting the actual number of SCIP Submittal Milestones reached during the month from the target number of SCIP Submittal Milestones and multiplying by $[***]. If the actual number of SCIP Submittal Milestones is less than [***]% of target, then
the dollar amount per missed Site shall not exceed $[***] reflecting an RF Design Standby Charge; provided that the Network Vendor charges Company. If the actual number of SCIP Submittal Milestones is below [***]%, then the dollar amount per missed
Site shall not exceed $[***] reflecting an RF Design Standby Charge; provided that the Network Vendor charges Company. As an example, if the actual number of SCIP Submittal Milestones for the applicable month is [***]% and that equates to [***]
([***]) Sites below the [***]% threshold, Contractor would pay Company an amount not to exceed $[***].

Measurement of the RF Design Standby
Charge will take place on a monthly basis.

All Network Vendor Charges will be set off against amounts owed to Contractor on a quarterly
basis.

For purposes of calculating total Network Vendor Charges per Site so that the $[***] is not exceeded, each RF Design Standby Fee
(e.g., $[***], $[***], or $[***]) will be assigned to a unique Ring/Site Identification Number, using the Company Site and Ring ID numbering convention.

PROJECT QUALITY PLAN  Section 2, Quality Management System





Quality Surveillance

The quality of specific work processes and/or products will be monitored via
periodic quality surveillance, conducted in accordance with the applicable Quality Services Department procedure.

Quality Audits

Internal quality audits will be conducted at planned intervals to determine if the Project QMS, as implemented, conforms to the planned
arrangements, ISO 9001 requirements, and Quality Manual and if it is effectively implemented and maintained.

External quality audits, as
part of supplier control, will be scheduled and conducted, as necessary, to support the Project QMS.

Functional Oversight

Functional oversight will be performed by both on project and off-project personnel. Oversight shall be in the form of monitoring,
review, and assessments of critical or significant functional activities, client interface issues, application of procedures, training, and staffing.

Monitoring and Measurement

In addition to conducting internal quality audits, quality surveillances,
and functional department assessments, internal work processes and products will be routinely measured. Supplier work processes and products will be monitored at suppliers facilities to verify that process and product requirements have been
met. The extent of monitoring will be commensurate with the importance of the product or service being procured.

Nonconformities

If a nonconforming product is identified, it will be controlled to prevent its unintended use in one of the following ways: by eliminating
the detected nonconformity, by authorizing its use under concession, or by taking action to preclude its original intended use or application.

Corrective Action and Preventive Action

Corrective action taken will be appropriate to the effects of the nonconformity
encountered. The causes of nonconformities will be determined and appropriate action taken to correct the conditions and prevent their recurrence.

Potential nonconformities and their causes will be determined. Appropriate action will be taken, if determined to be required, to prevent their occurrence.

Customer Satisfaction

Information relating to customer satisfaction (including customer complaints)
will be monitored to gauge whether customer requirements have been met. Appropriate action will be taken to enhance customer satisfaction.

Analysis of Data

Data from reviews of Nonconformity Reports, Corrective Action Reports, Management Review Output, internal
and external audit findings, and supplier performance evaluations will be analyzed for trends or identifying improvement opportunities. Corrective and/or preventive actions taken based on analysis results will be commensurate with the magnitude of
the problem and the risks encountered.

Continual Improvement

Corrective and preventive action processes will be used where planned results are not achieved. Statistical analysis techniques will be used as
appropriate to continually improve work processes.

Qualification of Suppliers and (Sub)Contractors

Suppliers and (Sub)Contractors who provide major components and services for the project will be evaluated and qualified by the appropriate functional
groups. The evaluations shall include but not be limited to the following: technical data, experience, safety, organization, personnel, and Supplier/Subcontractor Quality Management System.
