ARTICLE 13  ORBITAL PERFORMANCE INCENTIVES



|13.1 | General
|---- | -------

In addition to the Firm Fixed Price, as
set forth in Article 4.1, Contractor shall have the opportunity to earn, and Purchaser shall pay to the extent earned, the Orbital Performance Incentives for the Satellite in amounts as set forth in Exhibit F, TerreStar Satellite Orbital Performance
Incentives Payment Plan, all in accordance with this Article 13. Orbital Performance Incentives are comprised of two types: (i) the Quarterly Orbital Performance Incentives (based on the initial quarter commencing at Acceptance), further
described in Article 13.2.1, and (ii) the Scheduled Orbital Performance Incentive, payable in two (2) payments as further described in Article 13.2.2. Both types of Orbital Performance Incentives are payable on the dates determined in
accordance with Article 13.3. All measurements, computations and analyses made pursuant to this Article 13 shall be made in accordance with good engineering practice applying standards generally applicable in the aerospace industry.



|13.2 | Earning Orbital Performance Incentives
|---- | --------------------------------------



| | 13.2.1 | Daily Rate of Quarterly Orbital Performance Incentives. Subject to Article 13.2.7, for the Satellite Accepted pursuant to Article 10.2 hereof, Contractor shall earn Quarterly
Orbital Performance Incentives over the Orbital Performance Incentive Period at the daily rate based on the formula below (the Daily Rate), plus interest as provided in Article 13.3.
| | ------ | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|              |                        |                      |  |                                    
|------------- | ---------------------- | -------------------- |  | -----------------------------------
|Daily Rate  = |                        | Quarterly OPI Amount |  | x  Percentage of Performance Earned
|              | No. of Days in Quarter |                     

The Quarterly OPI Amount is set forth in Exhibit F under the column
titled Quarterly Incentive Payment, and the Percentage of Performance Earned shall be the smaller of the following ratios: (i) (the number of operational Forward Transmission Paths) ÷ 64 and (ii) (the number of
operational Return Transmission Paths) ÷ 160 where the number of operational Transmission Paths is defined in Article 13.2.3; provided, however, the Daily Rate of Quarterly Orbital Performance Incentives shall not be paid if the
Percentage of Performance

---

Earned, as calculated above, is less than seventy-two and one-half percent (72.5%). The Quarterly Orbital Performance Incentive amount to be paid is
illustrated in Exhibit F under the column titled Quarterly Incentive Payment for the Satellite assuming that the Percentage of Performance Earned equals one hundred percent (100%). The first day of the applicable Orbital Performance
Incentive Period shall be deemed to commence at 12:01 a.m. Greenwich Mean Time on the first day after Acceptance of the Satellite.



| | 13.2.2 | Scheduled Orbital Performance Incentives. Purchaser shall, promptly after receipt of the Summary In-Orbit Test Report, assess the condition of the Satellite based on the
Summary In-Orbit Test Report and early operations experience to determine whether, and to the extent that, Contractor has earned the Scheduled Orbital Performance Incentive. Subject to Article 13.2.7, Contractor shall have earned the Scheduled
Orbital Performance Incentive (or portion thereof as set forth below) as of the date that is ninety (90) days after Launch (or thirty (30) days after receipt by Purchaser of the Summary In-Orbit Test Report, whichever occurs later) (the
Scheduled OPI Commencement Date) according to the following formula:
| | ------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|

|Scheduled Orbital Performance Incentive amount earned =  
|                                                         
|Scheduled OPI Amount × Percentage of Performance Earned ×
|                                                         
|Percentage of Satellite Stated Life                      

where the Scheduled OPI Amount is identified in Exhibit F under the column titled
Scheduled Orbital Performance Payments, Percentage of Performance Earned is calculated in accordance with Articles 13.2.1 and 13.2.3, and the Percentage of Satellite Stated Life is the smaller of one hundred
percent (100%) of the Satellite Stated Life or the actual predicted Satellite life divided by fifteen (15) years; provided, however, that the Scheduled Orbital Performance Incentive shall not be paid if the Percentage of Performance Earned
multiplied by the Percentage of Satellite Stated Life as calculated above is less than ninety percent (90%).

| | 13.2.3 | Basis of Measuring Satellite In-Orbit Performance. Transmission Paths consist of two types of transmission paths on the Satellite. The Forward Transmission
Paths are individually those sets of equipment within the communications subsystem of the Satellite that provide a discrete path to receive communications signals from Earth at Ku band, translate and amplify such signals through a hybrid
matrix and transmit them to Earth at S band. The Return Transmission Paths are individually those sets of equipment within the communications subsystem of the Satellite that provide a discrete path to receive communications signals from
Earth at S-band (the service link), translate and amplify such signals and transmit them to Earth at Ku-band (the feeder link). The total number of Transmission Paths on the Satellite is 224 (64 Forward and 160 Return Transmission Paths). A
Transmission Path shall be deemed operational if the Satellite can provide full performance as required in Exhibit B, Satellite Performance Specification through such Transmission Path, after measurement and analysis uncertainty has been
taken into consideration. Specific test methods and precise criteria for operational shall be mutually agreed by the Parties, applying reasonable engineering judgment and criteria, on or before Satellite Technical Review Meeting 3.
| | ------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

For the purpose of determining an operational Forward Transmission Path only, the N×N hybrids shall be viewed as
individually connecting N separate inputs to N separate outputs. For example, the failure on one input path into an 8×8 hybrid shall be considered the failure of only one Forward Transmission Path.



| | 13.2.4 | On-Board Redundancy; Spares. In determining Orbital Performance Incentives, on-board redundancy and/or spare components shall be taken into consideration to maintain service
on the Satellite, and such use shall be deemed normal operating procedure for purposes of this Article 13 so long as the applicable criteria for earning Orbital Performance Incentives are met by the Satellite.

| | 13.2.5 | Storage
| | ------ | -------



| | A. | Orbital Storage. If Purchaser places the Satellite in Orbital Storage (other than due to the inability to operate for causes attributable to Contractor), Contractor shall
earn the Orbital Performance Incentives at the same rate as Contractor would be earning such incentives if the Satellite were in service.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | B. | On-Ground Storage. If after Satellite Pre-Shipment Review of the Satellite, Purchaser places the Satellite in on-ground storage, Contractor shall not be entitled to any
Scheduled Orbital Performance Incentives or any Quarterly Orbital Performance Incentives during the initial nine (9) months of such on-ground storage. If Purchaser places the Satellite in on-ground storage (other than due to causes
substantially attributable to Contractor and to the extent not otherwise excused under Articles 17 or 18; for clarification, Contractor shall not be liable hereunder for any delay in delivery of the SBAS Operational Component (as defined in the
SBN/SBAS Contract)) for more than nine (9) months, Contractor shall be paid the Scheduled Orbital Performance Incentive and the Quarterly Orbital Performance Incentives at the same rate as Contractor would be earning such incentives if the
Satellite were in service, commencing at the end of such nine (9) month period (with the initial Scheduled Orbital Performance Incentive payment to be made at the end of month ten (10) and the initial Quarterly Orbital Performance
Incentives payment to be made at the end of month twelve (12)); provided, however, such amounts shall be subject to a refund as described below. During each month of the initial nine (9) month storage period, unless Purchasers placement
of the Satellite in storage is due to causes substantially attributable to Contractor and not otherwise excused under Articles 17 or 18; for clarification, Contractor shall not be liable hereunder for any delay in the delivery of the SBAS
Operational Component), in addition to other customary storage charges to be agreed, Purchaser shall pay Contractor the non-refundable sum of [***]

[***] U.S. Dollars (US$[***]) per month of storage, representing interest on the unpaid Orbital
Performance Incentives. Once the Satellite is taken out of on-ground storage, (i) Purchasers obligation to pay interest pursuant to this Article 13.2.5.B shall terminate, and (ii) Purchaser shall not be obligated to pay any Orbital
Performance Incentives, unless or until (i) the Satellite is subsequently placed into on-ground storage (other than due to causes substantially attributable to Contractor), in which case this clause shall apply as if the Satellite had remained
in storage and/or (ii) Contractor has earned such Orbital Performance Incentives following the actual Acceptance of the Satellite. If the Satellite is Launched after Purchaser has paid any Orbital Performance Incentives under this Article
13.2.5.B, such amounts shall be deemed a pre-payment of the corresponding Orbital Performance Incentives due after actual Acceptance in accordance with Article 10.2. To the extent that, after actual Acceptance, Contractor does not earn the Orbital
Performance Incentives pre-paid by Purchaser under this Article 13.2.5.B, Contractor shall refund all or a portion of the pre-paid Orbital Performance Incentives, as applicable, plus interest on such refund, calculated at a rate of eight percent
(8%) per annum, compounded annually, from the time such corresponding Orbital Performance Incentives were pre-paid by Purchaser. Contractor shall pay such refund and interest on the earliest date upon which the invoices for such Orbital
Performance Incentive would have been issued.



| | 13.2.6 | Temporary Outages. A Transmission Path shall not be considered non-operational during a day if it is not operational during such day less than two (2) minutes per day
for such Transmission Path. Contractor shall forfeit the Daily Rate of Quarterly Orbital Performance Incentives for any Transmission Path that is not operational for a period of two (2) minutes or more; provided that such outage is not
attributable to the operation, directly or indirectly, of the Satellite by Purchaser.

| | 13.2.8 | Losses Attributable to Purchaser. If, as a result of any act or omission on the part of Purchaser or Purchasers representatives, consultants or
subcontractors (including the Launch Agency, but excluding Contractor and any of its subcontractors at any tier) in the Launch, orbit-raising, operation of, testing of, or communication with, the Satellite, or if due solely to causes not
attributable to Contractor or its subcontractors (other than extraordinary events customarily listed as Exclusions under launch and in-orbit insurance policies), the Satellite operates in a manner that is not in accordance with any
requirements for earning Orbital Performance Incentives (including the Satellite being a Total Loss), Contractor shall earn or continue to earn Orbital Performance Incentives with respect to the Satellite at the rate that applied (or would have
applied) prior to the act or omission resulting in degraded performance or Total Loss (subject to later adjustments pursuant to Articles 13.2.6 and 13.2.7, with respect to failures to meet the requirements for earning Orbital Performance Incentives,
not resulting from any such act or omission). In the event of a Total Loss attributable to Purchaser or its representatives, consultants or subcontractors (including the Launch Agency), or due solely to causes not attributable to Contractor or its
subcontractors as provided above, occurring in connection with an Acceptance based on an Acceptance in accordance with Article 10.2(ii), so long as this Contract has not been terminated (and continuing so long as TerreStar orders a replacement
Satellite), the Orbital Performance Incentives shall be paid at the same rate as Contractor would be earning such incentives if the Satellite were in service. If this Contract is terminated for other than Contractors default, or TerreStar 2 is
a Total Loss and TerreStar does not order a replacement satellite therefor, Contractor shall be deemed to have earned the corresponding amount

| | 13.2.10 | Incentive for Extended Life of the Satellite. Should Purchaser elect to continue the use of the Satellite operating beyond its Satellite Stated Life, Purchaser shall pay to
Contractor the amount of the Daily Rate for each day during such period(s) of continued use by Purchaser, provided the Satellite is not a Total Loss.
| | ------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 13.2.11 | Orbital Performance Incentive Payment Assurance. Within one (1) month prior to SPSR, unless Purchaser or any company that Controls Purchaser (Purchaser Parent
Company) is filing periodic reports with the Securities and Exchange Commission, Purchaser shall provide Contractor with a consolidated balance sheet of Purchaser and Purchaser Parent Company, as of the end of the prior fiscal year, and the
related consolidated statements of income, changes in equity and cash flows for such fiscal year. Such information shall be considered Proprietary Information of Purchaser and shall be subject to Article 31. In the event that
such information indicates that payment of the Orbital Performance Incentives in accordance with Article 13 is at high risk due to Purchasers and Purchaser Parent Companys financial condition, then the Parties shall promptly meet to
negotiate, in good faith, commercially reasonable steps to reduce such risk and provide reasonable assurance that Purchaser will be able to pay the Orbital Performance Incentives when they become due.

adjustment shall be reasonable and proposed in good faith. If Purchaser desires to proceed with the change after receipt of Contractors preliminary estimate, Purchaser and Contractor shall cooperate and negotiate in good faith and agree in a
timely manner to equitable adjustments in the Firm Fixed Price, Delivery schedules and other affected provisions of this Contract, and this Contract shall be amended in writing accordingly in accordance with Article 37.5. In the event the
Parties fail to agree on an adjustment (upward or downward) to the Firm Fixed Price, Delivery schedule or other affected provisions of this Contract with respect to a requested change, then Purchaser may direct Contractor to proceed with the
requested change, Contractor shall proceed with the directed change, the Parties shall continue to negotiate the adjustments to the Contract, and pending completion of such negotiations and as a condition for Contractor being obligated to proceed
with the directed change, the Parties in good faith shall agree upon and establish a reasonable payment schedule adjustment to compensate Contractor for the Work performed pursuant to the directed change, which payment schedule shall be adjusted as
part of the negotiated settlement for the directed change.

indemnification upon receipt thereof and shall provide the other Party, at its written request, with copies of all documentation relevant to such suit or claim. Failure to so notify the indemnifying Party shall not relieve the indemnifying Party of

no later than a reasonable time before the date on which any response to a complaint or summons is due, the indemnifying Party shall notify the Party seeking indemnification in writing if the indemnifying Party elects to assume control of the

defending such claim, the indemnifying Party shall be entitled to have sole control over the defense and settlement of such claim; provided that (i) the Party seeking indemnification shall be entitled to participate in the defense of such claim

seeking indemnification shall provide, at the indemnifying Partys request and expense, such assistance and information as is available to the Party seeking indemnification for the defense and settlement of such claim and (iv) the

relating to any claim in accordance with the preceding paragraph, the indemnifying Party shall not be liable to the Party seeking indemnification for any legal expenses incurred by the Party seeking indemnification in connection with the defense of
that claim. In addition, the indemnifying Party shall not be required to indemnify the Party seeking indemnification for any amount paid or payable by the Party seeking indemnification in the settlement of any claim for which the indemnifying Party
has delivered a timely Notice of Election if such amount was agreed to without the prior written consent of the indemnifying Party.

actively to defend such claim, the Party seeking indemnification shall have the right to defend and/or settle the claim in such manner as it may deem appropriate, at the cost and expense of the indemnifying Party. Provided that the Party seeking
indemnification acts in good faith, it may settle such claim on any terms it considers appropriate under the circumstances without in any way affecting its right to be indemnified hereunder. The indemnifying Party shall promptly reimburse the Party
seeking indemnification for all such costs and expenses.

reasonable efforts to obtain a waiver of subrogation and release of any right of recovery against the other Party and its Affiliates, contractors and subcontractors at any tier (including suppliers of any kind) and their respective directors,
officers, employees, shareholders and agents, that are involved in the performance of this Contract from any insurer providing coverage for the risks such Party has agreed to indemnify against under this Article 20.

ARTICLE 38  SECURITY INTEREST



|38.1 | Grant of Security Interest
|---- | --------------------------

As security for the
performance by Contractor of the Secured Obligations the Contractor hereby grants to Purchaser, and pursuant to Section 364 of the Bankruptcy Code, Purchaser shall have, a valid, binding, enforceable and perfected first priority lien on and
security interest in (collectively, the Security Interest) all of Contractors right, title and interest in, to and under the following property, whether now owned or hereafter acquired by Contractor and whether now existing or
hereafter coming into existence (collectively, the Collateral):

A. all Raw Materials, Work-in-Process and
Finished Goods; and

B. all proceeds (as defined in the UCC) of any of the foregoing.

Except as otherwise specifically provided herein, the Security Interest shall not be subordinate or pari passu with any other lien or security interest or
right of setoff or recoupment, and no lien or security interest or right of setoff or recoupment shall be permitted which shall be senior to or pari passu with the Security Interest. The grant of the Security Interest pursuant to this Article 38.1
is not in derogation of Purchasers rights as owner of any Raw Materials, Work-in-Process and Finished Goods as to which title has passed to Purchaser, and remains in Purchaser, as provided in this Contract. This Security Interest shall
automatically terminate upon Intentional Ignition or shall be released and extinguished pursuant to Article 21.2, 23.1.2, 23.1.5 and 23.2.3.



|38.2 | Right to Make Filings
|---- | ---------------------

Should Purchaser, in its
sole discretion (but not as a requirement hereunder), from time to time choose to file financing statements or other notices, instruments, agreement and documents or take other action to validate or perfect the Security Interest and in furtherance
of the grant of the Security Interest pursuant to Article 38.1, Contractor shall, and does hereby irrevocably authorize on behalf of Contractor and as Contractors attorney-in-fact to give, execute, deliver, file, record, obtain, and authorize
all financing statements and any other notices, instruments, agreements and documents, and take such other action as reasonably requested by Purchaser, to (i)

---

create, perfect, validate and preserve such Security Interest and the priority thereof and (ii) enable Purchaser to exercise and enforce its rights
hereunder with respect to such Security Interest (and all such documents and instruments shall be deemed to have been filed or recorded at the time and on the date of the entry of the Bankruptcy Order).



|38.3 | Corporate Records
|---- | -----------------

In furtherance of the grant of
the Security Interest pursuant to Article 38.1, Contractor shall indicate in Contractors corporate records the Security Interest that Purchaser has in the Collateral to the extent provided in this Article 38.



|38.4 | Perfected Security Interest
|---- | ---------------------------

Contractor represents
and warrants that the Security Interest granted to Purchaser constitutes a legal, valid and enforceable first priority security interest therein and upon the filing of UCC-1 financing statements in the office of the Secretary of State of Delaware
will be a perfected security interest in those items that can be perfected by filing under the UCC subject to no other liens or security interests other than after-acquired Junior Liens (as defined below). Contractor acknowledges that
Purchasers execution and delivery of this Contract provides value to Contractor.



|38.5 | Junior Liens
|---- | ------------

Contractor shall not lend, rent,
lease, transfer, pledge, grant a security interest in, or otherwise dispose of or encumber any portion of the Collateral or any right, title or interest therein except to Purchaser pursuant to this Contract and Contractor shall keep the Collateral
free from any security interest, lien, encumbrance or claim. Notwithstanding the foregoing, Contractor shall be permitted to grant silent junior liens (Junior Liens) on the Collateral to secure indebtedness of Contractor and
its Affiliates from time to time, including without limitation reimbursement obligations in respect of letters of credit (collectively, Permitted Debt), provided that the terms of such Junior Liens shall be reasonably acceptable to
Purchaser. Prior to granting any Junior Lien on the Collateral, Contractor shall provide written notice to Purchaser describing the circumstances of such Junior Lien (including without limitation the identity of the proposed holder of such Junior
Lien and the nature of the Permitted Debt). Within ten



- 116 -

[Use or disclosure of the data contained on this page is subject to the restrictions set forth in this Contract.]



---

(10) Business Days after receipt of such notice, Purchaser shall provide the terms for such Junior Lien that would be reasonably acceptable to Purchaser.
Contractor agrees and acknowledges that such reasonable terms may prohibit the holder of such Junior Lien from seizing, foreclosing on, selling or otherwise disposing of the Collateral or exercising other rights as a secured party, and may include
requirements that the holder of the Junior Lien hold in trust for Purchaser any amounts received in respect of the Collateral, so long as the Security Interest in favor of Purchaser remains in effect.



|38.6 | Periodic Inventory
|---- | ------------------

Upon the reasonable request of
Purchaser, Contractor shall provide Purchaser a written inventory describing the Raw Materials, Work-in-Process and Finished Goods as of the time of such request.



|38.7 | Remedies
|---- | --------

Purchaser shall have and be entitled to
exercise all the rights and remedies with respect to the Collateral of a secured party under the UCC (whether or not the UCC is in effect in the jurisdiction where Purchaser asserts the rights and remedies), such additional rights and remedies as
provided in this Contract, and such additional rights and remedies to which a secured party is entitled under the laws in effect in any jurisdiction where Purchaser may assert its rights and remedies. Upon termination of this Contract pursuant to
Article 23.1, or upon a termination by Contractor under Article 23.2.4 that is determined to have been wrongful, Purchaser shall have the right, subject to applicable export control restrictions and security regulations, to take possession of the
Collateral or any part thereof upon ten (10) days notice to Contractor for the purpose of effecting a sale or other disposition of the Collateral. Notwithstanding any provision of this Contract to the contrary, Purchaser shall not be permitted
to exercise any remedy as a secured party in respect of the Security Interest granted hereunder unless (i) Purchaser has terminated this Contract in whole pursuant to, and within the time limits provided in, Article 23.1 or (ii) Contractor
has wrongfully terminated this Contract under Article 23.5, and in either case, Purchaser retains a Security Interest as provided in this Article 38 and Contractor has failed to perform its obligations in such circumstances pursuant to Article 23
within thirty (30) days after required to do so (with respect to Contractor, a Termination Default).

---

|38.8 | Deficiencies
|---- | ------------

If the proceeds of sale, collection
or other realization of or upon the Collateral pursuant to Article 38.7 or otherwise are insufficient to cover the amounts due in clauses (i) and (ii) of the first sentence of Article 38.9, Contractor shall remain liable for any
deficiency. Purchaser shall not incur any liability as a result of the sale of the Collateral, or any part thereof, at any private sale pursuant to Article 38.7 conducted in a commercially reasonable manner and otherwise in compliance with the
UCC and applicable export control restrictions. Contractor hereby waives any claims against Purchaser arising by reason of the fact that the price at which the Collateral may have been sold at such a private sale was less than the price that might
have been obtained at a public sale or was less than the aggregate amount of the Secured Obligations, even if Purchaser accepts the first offer received and does not offer the Collateral to more than one offeree, so long as the sale was conducted in
a commercially reasonable manner.



|38.9 | Application of Proceeds
|---- | -----------------------

The Proceeds of any
collection, sale or other realization of all or any part of the Collateral pursuant to Article 38.7 shall be applied in the following order: (i) first, to the payment of the reasonable costs and expenses of such collection, sale or other
realization; (ii) second, to the payment in full of the Secured Obligations, and (iii) third, to the payment to the Contractor, or its respective successors or assigns, or as a court of competent jurisdiction may direct, of any surplus
then remaining.



|38.10 | Limited Power of Attorney
|----- | -------------------------

Without limiting any
rights or powers granted by this Article 38 to Purchaser while no Termination Default has occurred and is continuing, upon the occurrence and during the continuance of any Termination Default, Purchaser is hereby appointed the attorney-in-fact of
Contractor for the purpose of carrying out the provisions of this Security Interest and taking any action and executing any instruments that Purchaser may deem necessary or advisable to accomplish the purposes hereof, which appointment as
attorney-in-fact is irrevocable and coupled with an interest.



- 118 -

[Use or disclosure of the data contained on this page is subject to the restrictions set forth in this Contract.]



---

|38.11 | Contractor Cooperation
|----- | ----------------------

Contractor agrees that,
from time to time upon the written request of the Purchaser, Contractor will execute and deliver such further documents and do such other acts and things as Purchaser may reasonably request in order fully to effect the purposes of this
Article 38.



|38.12 | Intellectual Property Rights
|----- | ----------------------------

In connection with
the exercise by Purchaser of its rights as a secured party hereunder, Contractor hereby grants to Purchaser, to any person acquiring rights in the Collateral as the result of the sale, collection or other realization of or upon the Collateral, and
to any successor owner of the Collateral, the Intellectual Property rights and rights in data specified in Article 36, which rights shall survive any termination of this Contract.



|38.13 | Allowed Administrative Expenses
|----- | -------------------------------

The Secured
Obligations of Contractor and the rights, claims and priorities of Purchaser granted herein shall continue beyond and remain unimpaired and unaffected by any termination of this Contract.

be invited to participate in audits of Major Subcontractors. When there are subcontractor changes that affect a critical deliverable item, Purchaser and their consultants shall be informed and shall have the right to participate in the supplier
qualification process. Purchaser and their consultants shall have the right to participate in the selection of any supplier of critical items with unproven qualification status.

Purchaser and their consultants shall have the right to perform independent audits of the implementation and effectiveness of the Contractors Product Assurance Program. Specific ESD audits will be performed by
Purchaser and their consultants at various stages of the Program. Purchaser will notify and coordinate all formal Program audits with the Contractors Program Management Office. The results of Purchaser audits will be documented and transmitted
to the Contractors management for corrective action. Purchaser and their consultants shall be notified of the corrective actions taken. Audits at Subcontractors facilities will be coordinated with Contractor PA. Follow up reviews if
required, will be coordinated to ensure that adequate and continual corrective actions have been implemented.

3.2 NON-CONFORMANCE REPORTING

The Contractor will notify the Purchaser and their consultants of major non-conformances in accordance with CDRL item 18.

If a unit or subsystem develops two (2) identical failures or three (3) different types of failures during testing, the Contractor shall halt testing and
convene a Failure Review Board, with participation by Purchaser and/or their consultants, before any further action is undertaken.

The Contractor shall
conduct a re-test, in accordance with Spacecraft Performance Verification Requirements, for any test failure at unit or higher level during acceptance, protoflight or qualification testing. The Contractor shall conduct a system-level re-test for any
return of the spacecraft from the Launch Site for any reason. The scope of any re-test shall be mutually agreed between Purchaser and the Contractor.

3.3 PURCHASER RIGHT OF ACCESS

Purchaser representatives, including their consultants, shall be notified and have the right to participate in all technical reviews, manufacturing reviews, test, test readiness, and review board meetings relevant to
the quality and performance of flight hardware and software provided under this Contract. This includes participation in formal reviews of all failures and non-conformance dispositions.

Purchaser and their consultants shall have the right to monitor Engineering and Breadboard model testing performed under the Contract, witness all qualification, protoflight and acceptance tests, at both the
Contractor and Subcontractors facilities, and shall be given adequate notification in advance of the commencement of such tests.

In the event that
unit and system test data on parallel spacecraft programs are directly related to the validation of this Contract, Purchaser and their consultants shall have the right to witness such tests and review the pertinent data.

All surveillance activities conducted by Purchaser or their consultants shall not in any way replace the Contractors inspections, or relieve the Contractor of the
responsibility for ensuring the quality of the Deliverable Items.

Purchaser and their consultants shall be given access to all test data, and shall be
provided with copies of the test data, when requested. Purchaser and their consultants shall also be given access to all instrument calibration data.

The
Contractor shall provide Purchaser and their consultants with adequate workspace at any unit, subsystem or system test location to allow real time on-site test monitoring and data review. At system level testing, a terminal shall be made available

TerreStar Satellite Program  Technical Specifications



1  SCOPE

This document specifies the performance characteristics of the TerreStar 2-GHz GEO Satellite designed to relay digital voice and data traffic in the 2 GHz band frequencies. The satellite shall be compatible with the
launch constraints, restrictions, environments, and limitations of the launch vehicles and shall be capable of being placed in a geostationary orbit at the geostationary position of 111.1° W longitude.

The TerreStar 2-GHz GEO Satellite Space Segment consist of a spacecraft, ground-based beam forming (GBBF) subsystem, and tracking, telemetry and command subsystems.
Within this segment, two links are provided for communicating between gateways and users.



| | 1. | A forward link with Ku-band uplinks and 2-GHz band downlinks
| | -- | ------------------------------------------------------------



| | 2. | A return link with 2-GHz band uplinks and Ku-band downlinks
| | -- | -----------------------------------------------------------

The 2-GHz
band coverage is accomplished by employing spot beams, using the Satellite and the Ground Based Beamforming (GBBF) subsystem. The Satellite shall include a multi-element feed array and reflector antenna for the 2-GHz band coverage. The GBBF
processes the signals to and from the spacecraft S-band feed array elements.

The TerreStar communications payload provides two distinct links between the
gateways and the users. These links are accomplished with a large number of spot beams providing coverage to the continental United States, Canada, Alaska, Hawaii, Puerto Rico and U.S. Virgin Islands.

1  INTRODUCTION

1.1 SCOPE

This Spacecraft Test Plan (STP) defines the development, qualification, protoflight, and acceptance tests
that are performed as a standard on all Space Systems/Loral (SS/L) spacecraft during factory testing, at the launch base, and for in-orbit verification. Testing is performed at unit, subsystem, and satellite levels. The ground test program is
designed to demonstrate the performance of flight units in environments more stressful than those expected during the mission life. The purpose of this testing to show compliance with the Terrestar-2 Satellite Performance Specification as defined in
Exhibit B of the Contract.

This plan is SS/Ls proven baseline. Testing details can be modified by mutual agreement between Purchaser and SS/L.

1.2 TEST PLAN OBJECTIVES AND PHILOSOPHY

1.2.1
Objectives

The objective of the STP is to ensure that the satellite will satisfy and fulfill its mission requirements over its lifetime. The STP is
designed to prove that the spacecraft is capable of meeting its required performance specifications over the range of environments it shall encounter during its operational lifetime, including ground, launch base, and launch phases. All acceptance,
protoflight, qualification, and development tests conducted on spacecraft equipment shall follow the requirements of this test plan.
