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 H, 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 |  | × Percentage of Performance Earned
|             | No. of Days in Quarter |                     

The Quarterly OPI Amount is set forth in Exhibit H 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 H 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 H 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 Articles17 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.
| | ------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 13.2.7 | Total Loss of the Satellite. Without limiting the provisions of this Article 13, and subject to Article 13.2.8, Contractor shall not be entitled to unearned Orbital
Performance Incentives for the Satellite from and after the occurrence of a Total Loss of the Satellite; provided that any Orbital Performance Incentives paid under Article 13.2.5.B shall not be considered earned (until actually earned
after Acceptance), and shall be refunded to Purchaser in the event of a Total Loss.

| | 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 the TS -2 Contract has not been terminated (and continuing so long as TerreStar orders a replacement Satellite if TerreStar 2 is also a
Total Loss), 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 the TS-2 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 of Orbital Performance Incentives, to be paid promptly upon the later of (i) Purchasers
receipt of the proceeds from Launch and in-orbit insurance or (ii) such termination or determination of a Total Loss of TerreStar 2 where no replacement is ordered.
| | ------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 13.2.9 | Access to In-Orbit Data and Measurements. During the life of the Satellite, Contractor shall have access to the data records of the Satellite. The Parties will agree on or
before the Satellite Technical Review Meeting 3 as to the precise equipment and calibrations to be used for taking and/or making measurements, computations and analyses to determine whether any reduction is warranted in the Orbital Performance
Incentives that may be earned by Contractor.
| | ------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 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.

| | B. | Modify the whole or any part of the Work provided for herein; or
| | -- | ----------------------------------------------------------------



| | C. | Direct stop Work, by one or more orders, up to an aggregate of eighteen (18) months; provided, however, to the extent Purchaser issues a stop Work order on or after Milestone
24 (Complete Thermal Vacuum Testing) of Exhibit F, TerreStar 1 Payment Plan and Termination Liability Amount, directing Contractor to stop Work on the Satellite, such stop Work will not exceed cumulative twelve (12) months (or the balance of 18
months, whichever is less).
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 16.1.2 | Response to Change Request. Contractor shall respond to any such requested change in writing to Purchaser within thirty (30) days after receipt of such
requested change; provided, however, in the case of a stop Work direction, Contractor shall stop Work immediately to the extent specified by Purchaser. Contractor shall use commercially reasonable efforts to require its subcontractors with Major
Subcontracts to agree to a stop Work provision that minimizes Contractors costs and is consistent with the terms of this Article 16.1.2. In the event of a stop Work, Contractor shall use commercially reasonable efforts to mitigate costs and
shall cooperate in good faith with Purchaser in connection with actions taken by Contractor with respect to its subcontractors. If such change request causes an increase or decrease in the cost or the time required for completion of the Work to be
provided herein, or otherwise affects any other provision of this Contract, such response shall provide a non-binding preliminary estimate of the impact of the change request on the Firm Fixed Price (including costs associated with processing of the

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.

event of a termination under (ii) below to payment of actual direct costs incurred as a result of the stop Work order (e.g., reasonable termination liabilities with subcontractors and suppliers but not overhead or G&A costs). In the
event Purchaser directs a stop Work, within twelve (12) or eighteen (18) months thereafter, as the case may be (or within such portion of the maximum stop Work period remaining as provided in Article 16.1.1), Purchaser shall either:
(i) direct Contractor to resume Work hereunder, and the schedule and affected terms of this Contract shall be equitably adjusted due to such Work stoppage and the price shall be equitably adjusted to compensate Contractor for actual costs

for convenience under Article 21. For Purposes of Article 21, Purchasers termination liability (as may be adjusted pursuant to the foregoing) will be based on the effective date of the stop Work order being deemed the date upon which
Contractor was given written notice of Termination for purposes of Article 21.1.1.

Contractor was not in default under Article 23.1.1, or that the default was excusable under Articles 17 or 18, the rights and obligations of the Parties shall be the same as if the termination had occurred under Article 21; except that Contractor
shall also be entitled to recover its additional actual costs reasonably incurred due to such invalid default termination plus a markup of ten percent (10%) of such costs.

| | 23.2.2 | Termination Liability. In the event of termination pursuant to this Article 23.2, Contractor shall be paid as if such termination were for convenience pursuant to Article 21.
Further, if Purchasers failure to perform is a failure to pay Contractor invoiced amounts when due, Contractor shall be entitled to late payment interest pursuant to Article 5.3. Payment of any amount by any Financing Entity on behalf of
Purchaser shall relieve Purchaser from its obligation to make such payment in the corresponding amount. Payment of the total amounts (termination for convenience amounts plus interest on outstanding invoices) payable by Purchaser pursuant to this

Alternatively, Purchaser may request Contractor to make a reasonable, good faith effort to sell such items and to remit any sales proceeds to Purchaser
less a deduction for actual costs of disposition reasonably incurred by Contractor for such efforts, and, if not previously released and extinguished, any Security Interest or other right or interest that Purchaser has in such items hereunder or

to Article 23.1, and subject to the limitation of liability set forth in Article 30).

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



- 117 -

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



---

(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 (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



118



---

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.

|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.

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
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.

1  TERRESTAR DYNAMIC SATELLITE SIMULATOR

Space Systems/Loral (SS/L) will develop and deliver one complete Dynamic Satellite Simulator (DSS) for the Terrestar spacecraft to the Terrestar Satellite Control
Center. SS/L will also deliver an interim version of the Terrestar DSS. The DSS is a real-time interactive software simulation of the spacecraft operating in transfer, drift, and geosynchronous orbits. The simulator can simulate all attitude and
orbit control functions of a real spacecraft in all phases of the spacecraft life including various attitude control system failures.

The DSS is suitable
for:



| | 1. | Validating flight control procedures
| | -- | ------------------------------------



| | 2. | Ground station operator training for both normal and contingency operations
| | -- | ---------------------------------------------------------------------------



| | 3. | Validating the ground station software
| | -- | --------------------------------------



| | 4. | Validating spacecraft command sequences
| | -- | ---------------------------------------



| | 5. | Anomaly investigations
| | -- | ----------------------

The simulator is easily configurable to different
spacecraft orbit, attitude, and subsystem initial conditions for specific operator training scenarios.

The DSS consists of the following elements:



| | 1. | A real-time simulation computer and peripherals
| | -- | -----------------------------------------------



| | 2. | Ground station interface
| | -- | ------------------------



| | 3. | Simulation software

|1.2 | REAL-TIME SIMULATION COMPUTER AND PERIPHERALS
|--- | ---------------------------------------------

The DSS is a
real-time interactive system consisting of a single PC-type computer with dual Pentium IV processors running at least 3.0 GHz with 1 GBytes of memory and two hard-drives with a minimum of 36 GB of storage each. The operating system will be Windows
2000. The DSS computer can be delivered as a rack mount unit or as a standard office type tower depending on customer preference.

The real-time simulation
computer provides sufficient processing power to support all of the models, processor emulations and the user interface at real-time and faster rates. The real-time simulation computer will have the following peripheral devices:



| | 1. | 20-inch high-resolution color monitor (resolution of 1600x1200)
| | -- | ---------------------------------------------------------------



| | 2. | Two 36-GB internal hard drive
| | -- | -----------------------------



| | 3. | CD-ROM reader/writer
| | -- | --------------------



| | 4. | 3.5 floppy disk drive
| | -- | ----------------------



| | 5. | Standard keyboard and mouse
| | -- | ---------------------------



| | 6. | Network cabling as needed
| | -- | -------------------------



|1.3 | GROUND STATION INTERFACE
|--- | ------------------------

The real-time simulation computer is
configured to provide telemetry, command, ranging, and [***] interfaces to the ground stations real-time system via a Local Area Network (LAN). The simulator functionally models the necessary subset of the ground system IN-SNEC Cortex NT
interface specification needed to implement these functions. The simulator can receive spacecraft commands, send telemetry, receive ranging requests and send ranging information, via an Ethernet interface with the TCP/IP protocol. Either a 10base-T
or a 100base-T connection is available.

|1.4 | SIMULATOR MODELING
|--- | ------------------

The DSS modeling includes the following
elements:



| | 1. | Spacecraft processor emulation
| | -- | ------------------------------



| | 2. | Attitude dynamics modeling
| | -- | --------------------------



| | 3. | Propulsion subsystem
| | -- | --------------------



| | 4. | Telemetry, Tracking, and Command (TT&C) subsystem (including ranging)

| | -- | -----------------



| | 8. | Communications payload

| | 9. | Mechanisms
| | -- | ----------



| | 10. | Failure models
| | --- | --------------



|1.4.1 | Spacecraft Processor Emulations
|----- | -------------------------------

The real-time simulation computer
will run a high fidelity emulation of the spacecraft flight processors and software. This includes the firmware elements related to the ADCS, orbits, the propulsion subsystem, the T&C subsystem and the power. The SCE processor emulations
communicate with the dynamic spacecraft models via an emulation of the spacecraft 1553b data bus to the DCUs. The 1750 emulation uses an SS/L developed technology called the Dynamic Binary Translator (DBT) which allows the DSS to use the
actual flight software load module directly. This provides for the highest fidelity possible in an all software simulator. In addition, this technology allows flight software patches to be commanded and enabled just as they are on the actual
spacecraft.

In addition, the redundant SCE and processor will be modeled. Also included will be software models of the various interprocessor links that
exist on the actual spacecraft. These links will model the actual spacecraft data traffic this will permit realistic processor fail-over scenarios to be simulated. Also modeled will be the CCL tray interfaces to provide redundancy simulation.

| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------



|1.4.6 | Dynamic Power Model
|----- | -------------------

The dynamic power model is a source-and-sink
model of the power subsystem down to the box level with redundancies. It includes nonlinear models of the solar arrays and batteries, and spacecraft-power generation, storage, and distribution. It provides detailed dynamic power system telemetry
during all phases of the mission including shunt currents as a function of:



| | 1. | The seasonal variations of solar power

| | -- | ----------------------------------------------------------------------------



| | 10. | A user-settable I-V curve (less important for a voltage regulated bus)
| | --- | ----------------------------------------------------------------------

The power model will support all components of the charging system. These include modeling of charge/discharge converters and the Automated Battery Management (ABM). Failures of these components, except for the ABM, are accepted from the
user interface.



|1.4.7 | Dynamic Thermal Model
|----- | ---------------------

The dynamic model of the spacecraft thermal
behavior is described by approximately 500 thermal nodes connected to other nodes by conduction and radiation, and is integrated in real-time. The modeled temperatures include the effects of thrusters, the on/off status on electronic boxes, and Sun
thermal loading and deep-space cooling. The output of this model is mapped to the thermal telemetry data and is updated at a rate equal to the thermal telemetry multiplexed rate. This model will be tuned to provide thermal telemetry responses within
5 °C.

---

In addition, there is a separate dynamic battery thermal model containing approximately 200 nodes. This model will
provide battery temperature variations due to charging and discharging during eclipse operations. Thermal telemetry values can also be set as constants via the DSS console time tagged commands.



|1.4.8 | Communications Payload Model
|----- | ----------------------------

The communications payload model is
designed to accept spacecraft commands for the communications payload and accurately reflect all payload telemetry, including on/off status, switch positions, and gains. In addition, the payload model can simulate the effect of switching the
transponder from the active mode to the standby mode. This effect is implemented using a combination of user-settable values for the input power to the channel amplifier and spacecraft commands to the payload. The effect of the switching and gain
states are reflected as the appropriate responses in telemetry for the payload and power subsystem. In addition, the power consumption and the thermal dissipation of the communications subsystems units are modeled in the power subsystem model and
the thermal model, respectively, based on communication subsystems unit on/off status and the user-settable uplink RF power.



|1.4.9 | Mechanisms
|----- | ----------

The DSS approximately simulates the attitude dynamic
motions due to the deployment mechanisms of the solar arrays and antenna reflectors. This model outputs the deployment status to the spacecraft dynamics model for spacecraft attitude calculation and to the T&C subsystem for telemetry generation.
The models output the deployment status to the power subsystem model for power generation calculations. Deployment of each mechanism will be initiated by the associated deployment commands.



|1.4.10 | Failure Models
|------ | --------------

Table 3-1 provides a minimum set of failure models
that will be supported by the Terrestar DSS. The complete list would be a topic of the DSS Design Review (D-DR). It is SS/Ls intent to include as many spacecraft failures as possible that can be reasonably justified and modeled.

|1.5 | FAST MODE SIMULATION
|--- | --------------------

Fast mode simulation is the same as the
real-time simulator but runs at least 5 times faster than real-time. The user may specify the rate up to the maximum rate permitted. Fast mode simulation is very useful for spacecraft analysis and parametric studies. In addition, the execution can
be varied between fast mode and real-time as the simulation is running. Real-time operator interaction is not reliable due to the difficulty of human reaction to faster than real-time events, but time-tagged commands can be executed, and data will
be generated for later plotting.



|1.6 | SIMULATOR USER INTERFACE
|--- | ------------------------

The simulator user interface is
implemented on the real-time simulation computer and presents the simulator operator with an easy-to-use menu and icon-based graphical user interface. All of the simulator functionality and controls are accessible through the menus. In addition,
some commonly used functions are available on a button bar. This interface allows the operator to configure, monitor, and control the DSS and initiate various simulator failures. The basic features and capabilities of the user interface includes but
is not limited to:



| | 1. | Management, setup, editing and saving of multiple database sets
| | -- | ---------------------------------------------------------------



| | 2. | Display of spacecraft commands and telemetry
| | -- | --------------------------------------------



| | 3. | Commanding via single commands, time-tag commands, or commands files
| | -- | --------------------------------------------------------------------



| | 4. | Initiation of spacecraft anomalies and failures from a pick list
| | -- | ----------------------------------------------------------------

|1.6.1 | Satellite Body and Orbit Display
|----- | --------------------------------

A three-dimensional dynamic
display of the Terrestar satellite is incorporated into the DSS user interface. This display provides an interactive three-dimensional modeled environment that includes showing the Terrestar satellite in its orbit over Earth. Orbit attitude and
other outputs from the DSS are used to drive the three-dimensional display window. Multiple viewing options, including antenna coverages and sensor parameters, are provided, as well as spacecraft mechanism deployments. The three-dimensional dynamic
display system depicts three-axis attitude motions of the spacecraft, showing its orientation and orbital position with respect to Earth, the Sun, and the Moon. Functions performed by the system include:



| | 1. | Correct lighting angles, solar array angles, and eclipse conditions
| | -- | -------------------------------------------------------------------



| | 2. | Earth globe, with the Sun and the Moon, and vectors pointing to each shown in correct position

|1.7 | Real-time and Post-Processing Plotting
|--- | --------------------------------------

The DSS can real-time plot
both telemetry and non-telemetered data via an integrated strip-chart function. The strip chart is configurable throughout the duration of a simulation.

Offline plotting software is non-real-time software that runs on the real-time simulation computer and enables screen and laser printer plotting of pre-specified simulation non-telemetry variables and all telemetry after a simulation run is
completed. The plot data is obtained from disk files created by a data storage task during simulation execution. The simulation operator can select which variables to store from a large list and at which rate to store the selected variables from one
of four rates: 16 Hz, 4 Hz, 1 Hz, and 0.25 Hz. The data storage task can store at least five days worth of the entire spacecraft telemetry data and selected non-telemetered variable (such as true yaw). The user can select which variables will be
stored for each simulation from a preset list via the user interface. The plotting interface will be an easy to use graphical user interface similar to the simulator user interface.



|1.8 | SIMULATOR LIMITATIONS
|--- | ---------------------

The DSS has the following limitations:



| | 1. | Source code and the ability to build the DSS cannot be delivered
| | -- | ----------------------------------------------------------------



| | 2. | Simultaneous DSS simulations cannot be run on one workstation
| | -- | -------------------------------------------------------------



| | 3. | Breakpoints (checkpoints) are not available
| | -- | -------------------------------------------



| | 4. | The orbit epoch cannot be arbitrarily changed once a simulation has started. However, the simulation can be paused and the orbit fast forwarded to a later time, up to several days
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 5. | The thermal model coefficients are not tunable by the user. However, heat dissipations of the various on-board boxes can be changed by the user. Additionally, there is a
means to override the dynamically modeled thermal telemetry value with a user-input value
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 6. | Replacement or modification (other than parameter changes) of individual subsystem models in the DSS is not possible
| | -- | --------------------------------------------------------------------------------------------------------------------



| | 7. | The DSS operator display designs are not the same as the satellite ground control system displays. This is typically not a limitation, since satellite operator training typically
occurs in the actual ground station workstation, as driven by data from the DSS

| | 8. | The DSS provides its inputs and outputs only as Cortex formatted TCP/IP packets. Operation of the DSS is only from the DSS monitor and keyboard. There are third party products that
would provide the ability to run the DSS from a remote PC, but the performance may be unsatisfactory depending on many factors
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|1.9 | REVIEWS
|--- | -------

There will be one formal design review of the dynamic
simulator held at SS/L. A DSS Design Review (DR) will be held during the design and development phases. The DR will be held at EDC+12 months. The DR will cover the Spacecraft Simulator Requirements Specification, progress to date, the software and
hardware architecture of the simulator (including input/output descriptions), the simulator modeling addressing the level of fidelity, the DSS development schedule, the preliminary ICD and the test plan.



|1.10 | DOCUMENTATION
|---- | -------------

There are several deliverable documents associated
with, and needed for, the development, implementation, delivery, and use of the simulator. These documents are described in the following list. Other documents such as review minutes and other reports that will be delivered are described in the DSS
Statement of Work (SOW).



| | 1. | Simulator System Requirements Document.This document defines the simulator functional, performance, and interface requirements. A draft of this document will be provided at

| | 11. | Vendor documents of any off-the-shelf hardware and software incorporated into the simulator
| | --- | -------------------------------------------------------------------------------------------



|1.11 | DELIVERY AND INSTALLATION
|---- | -------------------------

SS/L will deliver and install an interim
version of the Terrestar DSS at launch minus 9 months. This will contain the most recent T&C database consistent with the most recent flight software that is incorporated into the DSS. Preliminary versions of all modeling features with the
exception of the bulk thermal model and the communications payload models will be included. An abbreviated informal site test of one-day duration will be provided and an informal hands-on two-day training course will be provided.

By launch minus 14 weeks, SS/L will have completed the delivery process of the final version of the Terrestar DSS at the Terrestar control center. This includes the
updating of the interim DSS to the final version of the DSS, the SAT, and training. The SAT will be performed immediately after the installation of the final version DSS. Satisfactory completion of the SAT and acceptance of the test results
constitutes delivery and acceptance of the Terrestar DSS.



|1.12 | SIMULATOR TEST AND VALIDATION
|---- | -----------------------------

There will be an abbreviated version
of the SAT based on a draft version of the SAT procedures for the interim delivery at launch minus 9 months. These tests will be denoted in the draft Acceptance Test Plan document as a subset of the full test plan.

A Customer-witnessed FAT will be conducted at SS/L prior to the updating of the interim DSS to the final version DSS. These tests are defined in the DSS Factory
Acceptance Test Plan and Factory Acceptance Test Procedures documents as derived from the DSS Requirements Document. The FAT will demonstrate that the DSS meets all of its functional requirements as described in the DSS Requirements Document as
derived from the contract DSS SOW and contract DSS technical specifications.

A Customer-witnessed SAT will be completed at the Terrestar control center
before launch minus 14 weeks. These tests are defined in the DSS Site Acceptance Test Plan and Site Acceptance Test Procedures documents. It is expected that the SAT will mostly be a subset of the FAT but that there will be a few additional tests in
the FAT due to differences in the test environments.

|1.13 | TRAINING
|---- | --------

Two days of informal training will be conducted with the
interim simulator delivery. This course will be mostly hands-on training and will be sufficient to allow the Terrestar DSS operators to perform all nominal DSS functions. Draft versions of the training slides and the Users Manual will be used as
part of this informal training.

One three day formal training course in the operation and maintenance of the simulator would be provided at the Terrestar
control center. This training course will be provided after the abbreviated SAT for the final version simulator delivery. This formal training course will be a three-day day course that consists of classroom and simulator hands-on instruction. The
classroom instruction will use the following material:



| | 1. | Course specific handouts
| | -- | ------------------------



| | 2. | The simulator user manual
| | -- | -------------------------



| | 3. | The spacecraft T&C list as available
| | -- | ------------------------------------

The simulator hands-on instruction is intended to provide simulator operators with training on the basics of running the
simulator at the simulator control console as well as running of a set of representative simulator scenarios. It is assumed that the operators to be trained on the simulator will already be familiar with spacecraft operations and the spacecraft
T&C list. In addition, this course will include DSS maintenance and administration and other advanced aspects such as DSS set-up and real-time scenario creation and editing, and DSS architecture and analytical models. This course should be
limited to a maximum of about six students because of the hands-on nature of the training. This course will not provide instruction on the operation of the spacecraft itself.



|1.14 | WARRANTY
|---- | --------

SS/L provides a one-year warranty for the dynamic
simulator, except for the commercially purchased software whose warranty will be limited to the applicable supplier-furnished warranty, if any. This warranty will start upon acceptance of the DSS. During the warranty period, the customer will
provide SS/L with any simulator anomaly reports for analysis. Based on these analyses, SS/L will correct, at its cost, any discovered deficiencies of required performance. The method of repairs of the DSS during this warranty period will be at
SS/Ls sole discretion and may include:



| | 1. | Software corrections, including modifications and validations
| | -- | -------------------------------------------------------------



| | 2. | Updates of documentation and configuration item data list
| | -- | ---------------------------------------------------------



| | 3. | Generation and delivery of new software releases
| | -- | ------------------------------------------------



| | 4. | Change of the flight code in the DSS to reflect patches uploaded
| | -- | ----------------------------------------------------------------



| | 5. | Changes of the DSS modeling to reflect significant changes on the Terrestar satellite after launch
| | -- | --------------------------------------------------------------------------------------------------

Any warranty related issues or problems must be demonstrated on the SS/L installed version of the DSS.

Beyond the one-year
warranty, SS/L will maintain the ability to provide simulator maintenance for the duration of the spacecraft life. This maintenance would be provided on a time and material basis. However, the DSS will be updated appropriately for any patch uploaded
to the satellite during its lifetime.
