"PRICE") is as follows:
(a) Satellites and Launch Vehicles
(i) thirty-four (34) Satellites $ [CONFIDENTIAL
TREATMENT]
(ii) three (3) Pegasus XL Launch Vehicle $ [CONFIDENTIAL
Launch Services TREATMENT]
(iii) Satellite Control Center Completion $ [CONFIDENTIAL
TREATMENT]
----------------
TOTAL $ 157,872.143
(b) Gateway Earth Station Completion $ [CONFIDENTIAL
TREATMENT]
Section 3.2 - Price for Options. The prices for the options referred
to in Sections 2.2 and 2.8 (the "OPTION PRICES") are as follows:
(a) Option for one (1) Pegasus XL Launch
Vehicle Launch Service $ [CONFIDENTIAL
TREATMENT]
(b) Option for the Replacement
Constellation $ [CONFIDENTIAL
TREATMENT]
(including Launch Vehicle Launch Services)
Section 3.3 - Adjustment to the Option Prices. The Option Prices, or
any of them, as the case may be, will be subject to annual retroactive
adjustments for inflation based upon changes to the Gross National Product
implicit price deflator index as reported by the United States Department of
Commerce, Bureau of Economic Analysis on or after December of each calendar
year (the "CURRENT INDEX"). The Gross National Product implicit price deflator
index value of [CONFIDENTIAL TREATMENT] shall be used as the baseline index
against which all such annually reported index values are compared. In the
event the differences between the current index value for the year then being
considered, and the baseline index value of [CONFIDENTIAL TREATMENT] exceeds
[CONFIDENTIAL TREATMENT] percent ([CONFIDENTIAL TREATMENT]%) per year, then the
monthly and milestone payments for those invoices or milestones scheduled to
have been
5
6
submitted or completed, as the case may be, during the year then being
considered, shall be increased by the difference (expressed as a percentage)
above the [CONFIDENTIAL TREATMENT]% annual inflation already included in the
milestone prices. This calculation is shown by formula 1 below. In the event
the difference between the current index value for the year then being
considered, and the baseline index value is less than [CONFIDENTIAL TREATMENT]
percent ([CONFIDENTIAL TREATMENT]%) per year, then the monthly and milestone
payments for those invoices or milestones scheduled to have been submitted or
completed, as the case may be, during the year then being considered, shall be
reduced by the difference (expressed as a percentage) below the [CONFIDENTIAL
TREATMENT]% annual inflation included in the milestone prices. This
calculation is shown by formula 2 below.
Formula 1: Percentage Increase = (A / [CONFIDENTIAL TREATMENT]) - B
----------------------------------
B
Formula 2: Percentage Increase = B - (A / [CONFIDENTIAL TREATMENT])
----------------------------------
B
A = The current index value for the year then being considered.
B = For adjustments to invoices or milestones scheduled to be
submitted or completed in 1995, as the case may be, this
number is [CONFIDENTIAL TREATMENT] (for 1996 it is
[CONFIDENTIAL TREATMENT]; for 1997 it is [CONFIDENTIAL
TREATMENT]; for 1998 it is [CONFIDENTIAL TREATMENT]; for
subsequent years, continue to multiply the prior year's number
by [CONFIDENTIAL TREATMENT] per year).
Section 3.4 - Taxes. (a) The Price does not include any federal,
state or local sales, use or excise taxes levied upon or measured by the sale,
the sales price, or the use of the items to be delivered or services required
to be performed hereunder. Orbital shall list separately on its invoice any
such tax lawfully applicable to the items to be delivered or services required
to be performed hereunder and payable by ORBCOMM Global. The Price shall not
however include any taxes on property owned by the United States Government, or
any U.S. or foreign federal, state or local income taxes imposed on Orbital.
(b) In cases where Orbital and/or ORBCOMM Global are wholly or

accordance with the requirements for achievement of Category A Milestones set
forth in Section 4.2 below (the "CATEGORY A MILESTONE ACHIEVEMENT CRITERIA").
(e) The total amount paid under 4.1(a), (b) and (c) shall not
exceed $[CONFIDENTIAL TREATMENT]. In the event costs incurred are less than
$[CONFIDENTIAL TREATMENT], the remaining amount shall be paid pro-rata upon
each launch.
(f) Schedule 4.1(f) sets forth the maximum cumulative payments to
be made by ORBCOMM Global under Sections 4.1(a), (b) and (c) during the term of
this Agreement. At any time during the term of this Agreement, ORBCOMM Global
shall not be obligated to make any payments associated with monthly invoices
and Category B Milestones to the extent that the cumulative costs exceed the
maximum payments identified in Schedule 4.1(f) at the relevant time until such
time where the cumulative costs are less than such maximum cumulative payments.
Section 4.2 - Category A Milestone Achievement. (a) Preliminary
Design Review, Critical Design Review and System Production Readiness Review
shall be deemed achieved upon conduct of the respective review meaningfully
addressing all significant areas as described in the Statement of Work, mutual
agreement on the scope of and schedule for action plan items and resolution of
any action items mutually agreed to be resolved as a condition of the related
Category A Milestone achievement. First Article Test shall be deemed achieved
upon successful completion of the First Article Acceptance Test Procedure. In
the event of substantial achievement of any milestone, Orbital shall be
entitled to invoice for a portion of the value with the balance to be invoiced
upon full achievement or waiver. In such event, any amount withheld shall be
at ORBCOMM Global's discretion, but shall be commensurate with the remaining
tasks and risks. Preliminary Design Review, Critical Design Review and System
Production Readiness Review shall be deemed fully achieved no later than the
first launch. In the event First Article Test is not fully achieved prior to
launch any remaining amount shall be earned to the same extent of On-orbit
Check Out achievement.
(b) Launch success for each launch service shall be deemed
achieved upon delivery of the Satellites to orbit in accordance with the orbit
criteria contained in Section 3.1.1 of the Launch Vehicle Statement of Work and
Specifications, as further defined in the interface control document for the
interface specification between the Launch Vehicle and the Satellite, which
interface control document shall be mutually agreed upon by Orbital and ORBCOMM
Global. In the event the Section 3.1.1 criteria are not achieved, but the
Satellites are placed in an orbit that make them useable to ORBCOMM Global,
Orbital shall be entitled to payment for partial launch success in an amount to
be determined by negotiation of the parties based on the usability of the
Satellites to generate revenues.
(c) On-Orbit Check Out for each plane of Satellites shall be deemed
achieved on a percentage basis as described in Schedule 4.2(c). In the event
of a failure of Satellite operation due to launch failure, the On-orbit Check
Out Milestone payment may be earned for On-orbit Check Out of the fourth plane
in accordance with the criteria described in Schedule 4.2. In the
8
9
event of failure or performance degradation below the criteria in Schedule 4.2
of any Satellite due to improper operation by ORBCOMM Global (to the extent
that such improper operation is not the result of Orbital's directives), such
Satellite shall be deemed fully functional for the purposes of On-orbit Check
Out Milestone achievement
Section 4.3 - Achievement of Milestones. (a) In the event that
Orbital fails to achieve any Category A Milestone in accordance with the
Category A Milestone Achievement Criteria on or before the scheduled completion
date shown in Exhibit C, ORBCOMM Global shall be relieved of its obligation to
pay the applicable amounts specified for such Category A Milestone until such
time as Orbital achieves such Category A Milestone in accordance with the
Category A Milestone Achievement Criteria or obtains a waiver in writing from
ORBCOMM Global for such achievement. The invoicing and payment procedure
referred to Section 4.1 shall then apply mutatis mutandis. This, together with
any additional rights and remedies ORBCOMM Global may have under Article 12 -
Termination, shall constitute ORBCOMM Global's exclusive right and remedy for
Orbital's failure to achieve any or all such Category A Milestones. Orbital's
failure to timely complete any milestone shall not relieve ORBCOMM Global from
its obligation to pay for other achieved milestones.
(b) If ORBCOMM Global concludes that the milestone event for which
any invoices have been submitted has not been successfully completed in
accordance with the requirements of this Agreement or that any condition
established by this Agreement as prerequisite to payment has not been
fulfilled, it shall provide Orbital written exceptions within ten (10) business
days after receipt of the invoice, specifying in detail the non-conformance.
The applicable payments shall be made within five (5) business days after
ORBCOMM Global's receipt of Orbital's response, in writing, addressing in
detail each of ORBCOMM Global's exceptions and, in the event of any Category A
Milestone, demonstrating to the reasonable satisfaction of ORBCOMM Global that
the milestone requirements have been successfully completed; provided, however,
if, with respect to any such Category A Milestone, ORBCOMM Global reasonably
concludes that Orbital's response to ORBCOMM Global's exceptions to be
non-responsive and so notifies Orbital as provided in Subsection 4.3(c) below,
ORBCOMM Global may, at its sole discretion, defer any unpaid amount of the
relevant Category A Milestone payment until the resolution of the matter as
described in Subsection 4.3(c) below.
(c) In the event ORBCOMM Global concludes that Orbital has been
non-responsive to ORBCOMM Global's exception to a Category A Milestone, ORBCOMM
Global shall notify Orbital thereof in writing (the "EXCEPTION NOTIFICATION")
within ten (10) business days after receipt of Orbital's response to ORBCOMM
Global's written exception. The Exception Notification shall (i) specify in
detail the reason(s) ORBCOMM Global believes Orbital's response to be
non-responsive, and (ii) advise Orbital formally that ORBCOMM Global intends to
withhold payment for such Category A Milestones until Orbital demonstrates to
the reasonable satisfaction of ORBCOMM Global that such Category A Milestone
has been achieved in accordance with the Category A Milestone Achievement
Criteria.

percentage of incurred costs, and in certain cases for a percentage of incurred
costs but only after successful completion of any Category B milestones. In
order to ensure ORBCOMM Global that the invoices that are submitted accurately
reflect (i) the actual incurred costs and (ii) the correct percentage of costs
to be invoiced under the terms of this Agreement, an outside auditor firm
selected by ORBCOMM Global may review the accuracy of submitted invoices under
this Agreement against Orbital's accounting books and records. In the event
that an error was made and ORBCOMM Global was overcharged, the amount of the
overcharge shall be determined by the auditors and the overcharged amount,
plus interest to be calculated at the prime rate of Morgan Guaranty Trust
Company of New York in effect on the first business day for each relevant month
from the date of overpayment, shall be refunded to ORBCOMM Global within five
(5) business days from the date of notification by the auditors. All expenses
of such audits shall be paid by ORBCOMM Global except that, to the extent that
there is an overcharge greater than Fifty Thousand Dollars ($50,000) finally
determined and that such determination is binding upon the parties, Orbital

States Government, and each party agrees to be responsible for and to absorb
the financial and any other consequences of any Property Damage it incurs or
for any Bodily Injury to, or Property Damage incurred by, its own employees
resulting from activities carried out under this Agreement, irrespective of
whether such Bodily Injury or Property Damage is caused by ORBCOMM Global,
Orbital or by their contractors, subcontractors, officers, directors, agents,
servants and employees and the Government and regardless of whether such Bodily
Injury or Property Damage arises through negligence or otherwise.
(b) ORBCOMM Global and Orbital shall each be responsible for such
insurance as they deem necessary to protect their respective property. Any
insurance carried in accordance with this Article 15 and any policy taken out
in substitution or replacement for any such policy shall provide that the

1 INTRODUCTION (FOR INFORMATION, SEE ORBCOMM SYSTEM DEFINITION)
2 SYSTEM ARCHITECTURE OVERVIEW (FOR INFORMATION, SEE ORBCOMM SYSTEM DEFINITION)
3 SATELLITE
The satellites specified in this document are designed to allow near
continuous time availability of ORBCOMM services to be provided with low capital
investment. Spacecraft capability requirements are designed to meet the first
five years of service demand.
3.1 FUNDAMENTAL CONSTRAINTS
Fundamental constraints refer to those system requirements which direct or
control all other aspects of the satellite configuration. For the ORBCOMM
satellites, as is the case with many others, these are the mass limits, useful
lifetime and the number of communications channels that are to be supported.
3.1.1 PHYSICAL LIMITS
The combined mass of 8(1) satellites, as launched, plus the adapter and
deployment structure, must be injected into orbit according to the parameters
stated below. Three or four planes will be launched into different ascending
nodes spaced to maximize coverage of latitudes between 25 and 50 degrees. The
operational orbit parameters for the satellites shall be:
- design orbit 775.0 km altitude, circular
- nominal ascending nodes spaced 135 degrees apart
- minimum altitude(2) 740 km
- right ascension nominal +/- 5 degrees at orbit insertion
of ascending node
- inclination 45.0 +/- 1.0 degrees
- phasing within plane 45 +/- 5 degrees
The relative spacing between the ascending or descending nodes of any two planes
shall not be less than 22.5 degrees three years after the launch of plane 3.
3.1.2 SATELLITE CHANNEL CAPACITY
The satellites are to be equipped with a communications payload configuration as
follows:
a) Subscriber Downlink Transmitter(s) (137.0-138.0 MHz) -- Each
satellite will be capable of generating either 4.8 or 9.6 kbps signals.
These signals will operate in the 137 MHz band and will be used to
communicate with the system users. To compensate for the low gain of
the subscriber handheld terminals the satellite transmitters will
produce a relatively high output EIRP.
- ----------
(1) Under mutually agreed upon circumstances 7 satellites per launch may be
acceptable.
(2) Based on target altitude of 775 km and 3 sigma dispersion
1
78
b) One Gateway Downlink Transmitter (137.0-138.0 MHz) -- The satellite
payload will contain one Gateway Downlink Transmitter. This transmitter
will operate in TDMA burst mode and will transmit messages to the
Gateway Earth Station (GES).
c) One Time and Frequency Standard Downlink Transmitter -- The Time and
Frequency Standard Transmitter will transmit a stable CW carrier at
400.1 MHz. This signal will be used by the subscribers to assist in
determining their geographical positions.
d) Six Subscriber Uplink Burst Receivers (148.0-150.05 MHz) -- The
Subscriber Receivers will receive and demodulate signals originating
in the Subscriber Transceivers. The receivers will be capable of being
tuned across the entire uplink frequency band.
e) One Gateway Uplink Receiver (148.0-150.05 MHz) -- The Gateway
Receiver receives the TDMA in-coming signal from a Gateway earth
station. This receiver will be capable of being tuned over the entire
uplink frequency band.
f) DCAAS Receiver/Processor -- The DCAAS Receiver/Processor scans the
uplink frequency band and is used to determine the best uplink channels
for the system users. This receiver is identical to those described in
d) and all seven Uplink Burst Receivers shall be capable of performing
the DCAAS power measurement function.
g) Fixed Frequency Receiver -- The fixed frequency receiver, if required,
will, among other things, upon receipt of a specific uplink coded
signal, initiate a general reset of the satellite or command a power
cycle specific units or subsystems.
3.1.3 LIFETIME
As a goal, the individual spacecraft shall be designed and constructed to meet a
five (5) year lifetime. Consideration of the lifetime shall include depletion of
consumable, loss of power generation capabilities, degradation of thermal
systems or other degradation due to wear out. Accepted, recognized space
industry practices shall be used to analyze the ability of the satellites to
meet this goal.
3.1.4 CONSTELLATION FREQUENCY PLAN (FOR INFORMATION)
The FCC approved frequency plan for the constellation downlink transmissions is
given in Table 1. Allocation of specific downlink channels to specific
satellites will be made by ORBCOMM. In operation, each plane of satellites is
expected to use a different set of subscriber frequencies. Alternating
satellites within a given plane will transmit on different downlink frequencies.
All satellites will use the same Gateway downlink frequency. This frequency plan
may be subject to further revision.
The required bandwidth shown in Table 1 includes the transmitter spectrum,
maximum Doppler shifts and oscillator instabilities. The authorized bandwidth
used to define the emission envelope in Section 3.1.4.1.1 is the required
bandwidth, listed in Table 1, minus twice the maximum Doppler shift and minus
the long-term oscillator instability.
2
79
The satellite Gateway receiver will operate with a center frequency of 149.61
MHz. The DCAAS system will be capable of operation over the 148.0-150.05 MHz
frequency band.
Additionally, each satellite will have a beacon transmitting at 400.1 MHz.

3.1.5 EMISSION LIMITATIONS
The ORBCOMM system is subject to certain emission limitations, imposed on
ORBCOMM by the Federal Communication Commission and through negotiations with
other users of the spectrum. In addition the military agencies of the US
government have imposed certain limits on the operations of all mobile satellite
systems operating in the 137 and 149 MHz bands. The following sections specify
the emission limitations that the ORBCOMM system must meet.
3.1.5.1 GENERAL TRANSMITTED EMISSION ENVELOPE
The emission spectra of the subscriber and gateway downlinks signals, including
out-of-band emissions(3), shall not exceed the emission envelopes shown in
figure 3-1 and 3-2 respectively.
- ----------
(3) From ITU RR 138 for the definition of out-of-band emission - "Emission on a
frequency or frequencies outside the necessary bandwidth which results from the
modulation process, but excluding spurious emissions". Note that necessary
bandwidth is defined as (RR 146) "For a given class of emission, the width of
the frequency band which is just sufficient to ensure the transmission of
information at the rate and with the quality required under specified

3.1.5.2 Cessation of Emission
The satellite shall be made capable of ceasing emissions by use of appropriate
commands from the ground station. Emissions shall cease with five (5) seconds of
the receipt of a valid command.The satellite shall automatically cease emissions
from any transmitter after a timeout

period following the most recent command to activate that transmitter.
3.1.5.3 Protection of National and International Meteorological Satellite
Operations
Operations of the ORBCOMM system have been coordinated with the
National Oceanographic and Atmospheric Administration (NOAA) through the
National Telecommunications and Information Agency. NOAA operations in the
137-138 MHz band will be limited to the following six sub-bands:
(1) 137.1250 - 137.175 MHz
(2) 137.3330 - 137.367 MHz
(3) 137.4850 - 137.515 MHz
(4) 137.6050 - 137.635 MHz
(5) 137.7530 - 137.787 MHz
(6) 137.8250 - 138.000 MHz
The power emitted in these bands by any ORBCOMM, satellite transmitter shall not
exceed - 153 dBW/m(2) as averaged over 50 kHz, at the surface of the Earth, in a
meteorological satellite sub-band. All transmitter on the satellite must meet
this roll off requirement. Practically, with the chosen modulations and EIRPs,
this means that the center frequency of a subscriber 15 kHz (25 kHz for the 9.6
kbps emission) channel must be at least 15 kHz (25 kHz for the 9.6 kbps
emission) from the edge of any of meteorological satellite frequency sub-band.
Similarly, the center frequency of the Gateway downlink 50 kHz channel must be
at least 40 kHz from the edge of any of Meteorological Satellite frequency
sub-band.
3.1.5.4 Protection of Radio Astronomy Operations(4)
The radio astronomy service operates in the following frequency bands:
(1) 150.05-153 MHz
(2) 406.1-410.0 MHz
Peak emissions, measured on the surface of the Earth, from the satellites shall
be limited to the following values -259 dBW/m(2) Hz for band (1) and -255
dBW/m(2) Hz for band (2).
3.2 COMMUNICATIONS SUBSYSTEM
The communications subsystem of the satellites is composed of three different
types of transmitters and two different types of receivers as described in
Section 3.1.2, Satellite Channel Capacity. The following paragraphs address
these units on a link by link basis.
3.2.1 SUBSCRIBER DOWNLINK TRANSMITTER (137.0-138.0 MHz)
The satellite payload will contain a Subscriber Transmitter. This Transmitter
will utilize the Earth pointing antenna. The Subscriber Transmitter will meet
the following specification.

82
3.2.1.1 Effective Isotropic Radiated Power (EIRP) and EIRP Steps
Each carrier of the 137 MHz subscriber downlink transmitters shall deliver a
minimum of [CONFIDENTIAL TREATMENT] dBW EIRP [CONFIDENTIAL TREATMENT] degrees
off boresight. The peak transmitter power will be able to be reduced, by ground
command, in at least six steps. The step size will nominally be [CONFIDENTIAL
TREATMENT] dB. The transmitter EIRP, as a function of the angle from the
antenna boresight, will not exceed the roll off contained in the mask in Figure
3-3.
[GRAPHIC MATERIAL DELETED AND FILED WITH THE COMMISSION] [CONFIDENTIAL
TREATMENT]
3.2.1.2 Subscriber Transmitter Frequency Range and Tuning
The subscriber downlink transmitter shall be capable of transmitting on any
frequency defined by the following formula:
Transmit Frequency = [CONFIDENTIAL TREATMENT] +[CONFIDENTIAL
TREATMENT] * N
where: N is an integer in the range: [CONFIDENTIAL TREATMENT] less
than = N less than [CONFIDENTIAL TREATMENT]
3.2.1.3 Subscriber Transmitter Stability
The following stability requirements shall be met over all spacecraft predicted
environmental conditions and operating modes while on orbit. This requirement
refers to the signal as transmitted by the spacecraft, without regard to Doppler
effects.
3.2.1.3.1 Long Term Frequency Stability
The long term stability shall be such that the transmit frequency accuracy is
within +/-[CONFIDENTIAL TREATMENT] kHz of the desired tuned frequency with the
adjustments described in 3.2.1.3.2 being required no more often than once each
30 days.
6
83
3.2.1.3.2 Frequency Adjustment Capability
It shall be possible to tune the oscillator in [CONFIDENTIAL TREATMENT]
steps to a precision of +/- [CONFIDENTIAL TREATMENT] Hz under command from the
ground. The number of steps shall be sufficient to cover twice the expected
aging range over the life of the spacecraft.
3.2.1.3.3 Short Term Frequency Stability
The transmitter short term stability shall be better than [CONFIDENTIAL
TREATMENT] measured over a [CONFIDENTIAL TREATMENT] minute period.
3.2.1.3.4 Output Power Stability
The transmitter output power shall not vary by more than [CONFIDENTIAL
TREATMENT] dB RMS over a [CONFIDENTIAL TREATMENT] minute period including
maximum expected on-orbit temperature rates of change at the unit.
3.2.1.4 Subscriber Transmitter Phase Noise
The phase noise introduced on each transmitted carrier shall not exceed the
mask given in Figure 3-4. For frequency offsets greater than 10 kHz, the phase
noise shall not exceed [CONFIDENTIAL TREATMENT]dBC/Hz. The transmitter shall be
capable of transmitting an unmodulated test signal that exercises all paths in
the transmit chain for the purposes of measuring phase noise, frequency
stability, unwanted emissions and intermodulation.
[GRAPHIC MATERIAL DELETED AND FILED WITH THE COMMISSION]
3.2.1.5 Unwanted Emissions
When transmitting an unmodulated carrier spurious emissions(5) shall be the
lower of [CONFIDENTIAL TREATMENT] dB per [CONFIDENTIAL TREATMENT]
- ----------

frequency or frequencies which are outside the necessary bandwidth and the level
of which may be reduced without affecting the corresponding transmission of
information. Spurious emissions include harmonic emissions, parasitic emissions
and frequency

84
kHz below the level of that carrier or that shown in Figure 3-1.
3.2.1.6. Subscriber Downlink Modulation
The downlink to the subscribers shall be modulated at 4800 or 9600 bps under
software control. The modulation will occur with a bit clock stability of 1
part in [CONFIDENTIAL TREATMENT] and a bit clock jitter of less than one
percent RMS. The modulation format is Symmetric Differential Phase Shift Keying
(DPSK). The data is differentially encoded in transmission with the 'one' data
state causing a [CONFIDENTIAL TREATMENT] degree positive phase shift of the
carrier and the [CONFIDENTIAL TREATMENT] data state causing a [CONFIDENTIAL
TREATMENT] degree negative phase shift of the carrier. The modulation symbols
will be filtered to reduce out-of-band emissions. Raised cosine [CONFIDENTIAL
TREATMENT] roll off filtering will be employed. The transfer function of the
[CONFIDENTIAL TREATMENT] root raised transmit narrow band filter, before
implementation, is provided in the physical layer ICD. The combined degradation
of the subscriber downlink modulation and the specified reference demodulator
shall not exceed [CONFIDENTIAL TREATMENT] dB with respect to a theoretical
implementation as established in Annex A. A Torrey Science Modem shall be used
as the reference demodulator. The amount of implementation loss less than
[CONFIDENTIAL TREATMENT] dB shall reduce the required EIRP under 3.2.1.1 up to
a maximum of [CONFIDENTIAL TREATMENT] dB.
3.2.1.7 Duty Cycle
[CONFIDENTIAL TREATMENT]
3.2.1.8 Polarization
The Subscriber Transmitter will transmit using right hand circular polarization
with an axial ratio equal to or less than [CONFIDENTIAL TREATMENT] dB over all
azimuth angles and off-boresight angles from [CONFIDENTIAL TREATMENT] to
[CONFIDENTIAL TREATMENT] degrees. The required EIRP in 3.2.1.1 may be reduced
in dBW by the amount in dB that the axial ratios are less than [CONFIDENTIAL
TREATMENT] dB over the required pattern.
3.2.1.9 Intermodulation Products
The ORBCOMM satellite frequency plan, tentatively described in section Table 1,
is designed around a number of frequency subbands (see Section 3.1.5.2) in which
other satellite services operate. The meteorological satellite service is one of
these other services. Under the FCC and International Telecommunications Union
regulations the ORBCOMM system must not cause harmful interference to other
services. Of all the space services operating in this band, the meteorological
satellite service has the most stringent interference criteria of -156 dBW/m(2)
in 50 kHz on the surface of the Earth. The intermodulation products generated by
transmitters on an ORBCOMM satellite shall not cause harmful interference to the
meteorological satellite service.
3.2.1.10 Dynamic Control of Output Power and Data Rate
It shall be possible to independently control the output power and data rate of
the subscriber
- -------------
conversion products, but exclude out-of-band emissions".

85
transmitter as described in this section. The active pattern for the
combination of data rate and power setting shall be under the control of the
network software which shall from time to time update this pattern. The
mechanism for this update shall be via a message from the network software to
the transmitter control process as defined in the relevant ICD. This command
shall consist of [CONFIDENTIAL TREATMENT] bit control words and [CONFIDENTIAL
TREATMENT] bit control words.
The subscriber downlink is organized into a superframe consisting of
[CONFIDENTIAL TREATMENT] second subframes. Each subframe begins with a twelve
byte packet known as the synchronization segment. Within this synchronization
segment is an explicit and unique frame number ranging from zero to fifteen.
Each synchronization segment shall be transmitted at 4800 bps, regardless of
the data rate of the subsequent portion of the subframe. The remainder of the
subframe "n" is transmitted at either 4800 bps or 9600 bps depending on the
state of bit(n) of the first [CONFIDENTIAL TREATMENT] control word described
above ([CONFIDENTIAL TREATMENT] is 4800 bps and [CONFIDENTIAL TREATMENT] is
9600 bps).
The transmit power level for subframe "n" will be one of the two levels
specified in the [CONFIDENTIAL TREATMENT] bit control words, (High Power Mode,
Low Power Mode), described above based upon the state of bit(n), of the
[CONFIDENTIAL TREATMENT] bit control word.
This power/data rate combination shall remain in effect until another command
message is received.
3.2.2 GATEWAY DOWNLINK TRANSMITTER (137.0-1380 MHz)
The payload will contain a Gateway Downlink Transmitter. This transmitter will
support the communication link with the system Gateway Earth Station.
3.2.2.1 Gateway Transmitter EIRP
The gateway downlink transmitter shall deliver a minimum of [CONFIDENTIAL
TREATMENT] dBW EIRP, within [CONFIDENTIAL TREATMENT] degrees off boresight. If
linear polarization is used the EIRP shall be a minimum of [CONFIDENTIAL

relative phase shifts.
3.2.7.5 Fixed Frequency Command Receiver Dynamic Range
The Fixed Frequency Command Receiver shall meet performance specifications at
an input to the subscriber antenna of -[CONFIDENTIAL TREATMENT] dBm and under
the interference conditions described in section 3.2.3.4.
3.2.7.6 Fixed Frequency Command Receiver Duty Cycle
[CONFIDENTIAL TREATMENT]
3.2.7.7 Fixed Frequency Command Receiver Polarization
The fixed frequency command receiver shall operate through the subscriber
receive antenna.
3.2.7.8 Fixed Frequency Command Receiver Command Set
The accepted commands shall be uniquely addressable to each satellite.
[CONFIDENTIAL TREATMENT] The reset command, when received, will remove power
from a particular unit or subsystem for a time sufficient to clear any latchup
condition in the microprocessors and/or digital signal processor in the unit.
Upon the re-application of power the effected unit shall automatically re-boot.
There shall also be a self-check command with corresponding telemetry.
The receiver is intended to be an independent functional path; therefore, to
the greatest extent possible it shall not be affected by any failures or
anomalous conditions of the satellite bus or payload.
3.2.8 MESSAGE PROCESSING REQUIREMENTS
Message processing refers to the creation, interpretation and routing of
packets to carry out the functions of the ORBCOMM system. This includes:
generation of system information and communications control as defined in the
following paragraphs.
3.2.8.1 Throughput
The spacecraft processor must be able to perform all required packet based
functions under the following loading(8):
- ----------------------
(8) These loading levels represent long term mean levels at the peaks
([CONFIDENTIAL TREATMENT] minutes). Testing will be done with Poisson
23
100
a) VHF Uplink Channels -- Packets per minute at a rate equivalent to
[CONFIDENTIAL TREATMENT]% of all slots containing detectable packets;
b) VHF Downlink Channels -- All channels (continuous and surge) loaded to
[CONFIDENTIAL TREATMENT]% of capacity with message traffic to the
subscribers (the rest is system overhead, ACKS, and polling commands);
c) UHF Downlink to Subscriber -- Since the UHF transmission is a beacon
there are no packet based functions;
d) Gateway Uplink and Downlink -- All packets received from subscriber are
downlinked to the gateway and all packets sent to subscribers are
uplinked from the gateway.
3.2.8.2 Response Times
Under the loading described above the following maximum response times are
expected:
a) Relay of Subscriber Uplink Packets -- Uplinked traffic from the
subscribers will be placed in the gateway downlink queue within
[CONFIDENTIAL TREATMENT] milliseconds of the reception of the last bit
of an error free subscriber uplink packet.
b) Gateway Uplink Acknowledgment -- A positive acknowledgment shall be in
the gateway downlink queue within [CONFIDENTIAL TREATMENT] milliseconds
of the reception of the last bit of an error free gateway uplink packet.
c) Relay of Subscriber Downlink Packets -- Traffic to the subscribers,
uplinked from the gateway will be placed in the subscriber downlink
queue within [CONFIDENTIAL TREATMENT] milliseconds of the reception of
the last bit of the error free gateway uplink packet containing the
traffic to relay.
3.2.8.3 Message Storage
Packets are not normally required to be stored on the satellite any longer than
it takes to process them and clock them out of the downlink queues. The
exception to this is the "Globalgram", store and forward, transport function
which is to be used whenever there is no NCC connected to the spacecraft. A
minimum of [CONFIDENTIAL TREATMENT] megabytes of memory shall be reserved to
store such Globalgrams in an analogous manner to the way in which telemetry is
archived when there is no virtual circuit available to the SCC.
3.2.8.4 Maximum CPU Loading
A 30% margin in CPU capacity for all CPUs handling communication traffic and
telemetry, excluding DSPs, will be maintained over that required by both the
ORBCOMM Network software and satellite bus software at peak traffic loading and
under realistic satellite operational modes.
- ---------------------
model traffic generators with these mean levels of packet generation.
24
101
3.2.9 Subscriber Network Communications Control
Each ORBCOMM satellite serves as a communications controller for all subscriber
terminals that are receiving and processing the control channel transmitted by
that satellite. Communications control consists of:
a) Dynamic allocation of the uplink channel pool;
[CONFIDENTIAL TREATMENT]
c) Reservation Mode Channel Assignment; and
d) Downlink traffic management.
3.2.9.1 Uplink Channel Dynamic Allocation
The satellite uses a technique called the Dynamic Channel Activity Assignment
System (DCAAS) to allow the subscriber terminals to communicate effectively in
the presence of nearly co-channel uplink interference. This allows uplink
channel frequencies to be reassigned in response to measured and predicted
statistical time variation of channel use by the interfering services. The
software to be used to control the DCAAS functions in the subscriber receivers
shall be provided by ORBCOMM. All of the subscriber uplink receivers shall be
able to function as DCAAS receivers under software control.
[CONFIDENTIAL TREATMENT]
3.2.9.3 Reservation Messaging
Messages are transmitted in a reservation or polled mode in which the
subscriber is allocated a receiver and time-slot in which to transmit a message
packet. The frequency and time corrections gained from the previous
acquire/communicate cycle are be used when transmitting the reservation burst.
Uplinks used for reservation access from the subscribers have a similar format
to the random access, but also indicate the amount of data transmitted following
the preamble as assigned by the network. This format is used for inbound message
packets and Globalgrams. (See, Part 2 of the ORBCOMM System Definition,
entitled ORBCOMM System Architecture Overview for specific formats)
25
102
3.2.9.4 Downlink Traffic Management
Each satellite may have more than 1 downlink channel active. [CONFIDENTIAL
TREATMENT]
3.3 SATELLITE BUS
3.3.1 POWER SUBSYSTEM
The Power Subsystem supplies DC power to the bus and the communications
payload. Prime DC power will be obtained from solar arrays. Batteries will be
used to supply power during the eclipse periods. As a minimum, the Power
Subsystem shall provide the necessary electrical power to operate the
communications payload receivers, transmitters and processors for the required
duty cycles.
During low voltage operations, the power subsystem will be designed to have
load shedding capability such that appropriate portions of the payload will be
dropped from the power system prior to the command and telemetry functions.
Under very low voltage conditions, the satellite will be autonomously placed
into a safe condition from which it will automatically recover if bus voltages
rise. The power management system of the spacecraft shall only shut off the
transmitters in an emergency situation. Full operation will be restored with
ground intervention.
Battery charge control shall be autonomous in accounting for changes in battery
temperature and battery capacity over time. The battery charge control
algorithm shall be designed to maximize battery life. Sufficient power system
telemetry will be provided to permit the battery charge/discharge rate to be
calculated on the ground to within [CONFIDENTIAL TREATMENT] accuracy.
It shall be possible to power cycle each unit or subsystem on the spacecraft
under ground command. All power system switches shall be ground-commandable.
3.3.1.1 BATTERY DESIGN LIFE
Battery capacity shall be sized to provide for five years(9) of operation in
the design orbit at the duty cycles specified in section 3.3.1.5.
- ------------------
(9) For the purposes of demonstrating battery life the Contractor may assume
that following: Duty cycles shown in the table in 3.3.1.5 may be reduced,
in eclipse, to meet this lifetime requirement. In particular, the STX may
have to be backed down by up to 2 dB in eclipse, in relation to the Low
Power Mode, during the first 2.5 years of life. This actions may be
necessary to extend the operational lifetime of the batteries to 5 years.
26
103
3.3.1.2 Overvoltage and Undervoltage Protection
The power system and the individual units shall be designed so that no unit
will be damaged as a result of bus voltages between [CONFIDENTIAL TREATMENT]
volts and the worst-case maximum expected voltage for each power bus.
3.3.1.3 Solar Array
Solar arrays must sustain any expected shadow geometry without damage. The
cells of the arrays shall be laid out to minimize shadowing losses and induced
magnetic moments.
3.3.1.4 Solar Array Lifetime
The solar array shall be able to supply the required DC power to meet the duty
cycle requirements of section 3.3.1.5 after five years of operational the
design orbit. The analysis of degradation shall take into account lifetime
radiation dosage, contamination of arrays, degradation of cover slides, worst
case thermal conditions and any expected ACS performance degradations.
3.3.1.5 Unit Level Power Consumption Duty Cycles
The unit level duty cycles are given in Table 2.
The spacecraft power subsystem shall be capable of operating all units at power
levels consistent with each unit at its maximum expected steady state power
consumption for a sustained period.
TABLE 2 UNIT LEVEL DUTY CYCLES
unit duty cycle

Subscriber Transmitter Low Power Mode(10) [CONFIDENTIAL TREATMENT]
Subscriber Transmitter High Power Mode [CONFIDENTIAL TREATMENT]
Subscriber Receivers 1-6 [CONFIDENTIAL TREATMENT]
Gateway Transmitter [CONFIDENTIAL TREATMENT](11)
Gateway Receiver [CONFIDENTIAL TREATMENT]
UHF Beacon [CONFIDENTIAL TREATMENT]
The power system shall be sized to be able to support all required bus power
consumption and the following communications unit duty cycles, averaged over
the orbit, for [CONFIDENTIAL TREATMENT]% of all orbits at the end of the fifth
year of operation. Duty cycles in eclipse periods will be the same as in
sunlight.
- ---------------
(10) High Power Mode is defined as operation at the maximum EIRP as defined in
3.2.1.1. Low Power Mode is defined a operation at EIRP of [CONFIDENTIAL
TREATMENT] dB below that of the High Power Mode.
(11) Unit is active at all times, [CONFIDENTIAL TREATMENT] out of the
[CONFIDENTIAL TREATMENT] downlink bursts are transmitted.
27
104
3.3.2 ATTITUDE CONTROL/STATION KEEPING SUBSYSTEM
The Attitude Control System (ACS) must maintain nadir(12) pointing accuracy
within [CONFIDENTIAL TREATMENT] degrees Circular Error Probability (CEP) and
[CONFIDENTIAL TREATMENT] degrees [CONFIDENTIAL TREATMENT] sigma. The ACS shall
include an autonomous self righting capability.
Each spacecraft shall be kept at a relative position in the orbit within
+/-[CONFIDENTIAL TREATMENT] degrees of nominal. If a propulsive station-keeping
system is employed, each satellite will be capable of being repositioned twice
during the lifetime on the constellation. Repositioning will require the
satellite to be moved [CONFIDENTIAL TREATMENT] degrees, relative to its starting
position in the orbit plane within [CONFIDENTIAL TREATMENT] days. Total delta V
required for a mission life will be determined. The ACS/Station Keeping System
will be sufficient to meet mission requirements with a [CONFIDENTIAL TREATMENT]
margin.
There are no cross-plane station keeping requirements.
The satellite shall be capable of maintaining any worst case attitude for an
indefinite period of time without sustaining damage due to over- or
under-temperature and with no ground intervention. On-board software to control
heaters and to reduce transmitter power may be employed to meet this
requirement.
3.3.3 NAVIGATIONAL REQUIREMENTS
The on-board GPS receiver shall be utilized to determine satellite position,
velocity and GPS time at a minimum of [CONFIDENTIAL TREATMENT] second intervals.
The position and velocity shall be converted to Earth Centered Earth Fixed
(ECEF) Cartesian coordinates for insertion into the subscriber downlink control
channels. Summary data, taken at maximum of [CONFIDENTIAL TREATMENT] minute
intervals shall be stored for ten orbits. This shall be made available for
downlink telemetry transmissions.
The navigation processing functions can also use orbital elements uplinked from
the Spacecraft Operations Center to calculate current orbit position as a
function of GPS time. This orbit determination will be combined with the outputs
from the GPS receiver, using a Kalman filter or other technique, to remove a
large portion of the "selective availability" degradation in the C/A code. This
orbital information will be transmitted to the user terminals, via the downlink
control channels, allowing them to calculate their position based on Doppler
frequency measurement. Spacecraft position shall be communicated to the ORBCOMM
network software to an accuracy of [CONFIDENTIAL TREATMENT] meters (spherical
error probability, SEP) and spacecraft velocity shall be communicated to the
subscriber terminals to an accuracy of [CONFIDENTIAL TREATMENT] meters per
second RMS.
3.3.4 TELEMETRY, TRACKING, AND COMMAND SUBSYSTEM
The telemetry system shall include a wide range of voltage, current,
temperature, attitude and other sensors. This data needs to be archived and/or
monitored for exceptions for the six or seven orbit duration when a spacecraft
is not within view of the U.S. The NCC/GES link and network layers allow
connection to any GES to send commands or retrieve telemetry. Telemetry will be
downlinked using packets in an identical manner as the ORBCOMM traffic packets
- ---------------
(12) The "nadir" direction is defined as the direction from the satellite to the
center of the Earth.
28
105
collected by the satellite. Priority will be given to traffic packets unless the
satellite is explicitly commanded to "maintenance" mode. A basic set of "core"
telemetry should always be transmitted, with higher volume archive "dumps" made
on command from the ground control stations.
"Tracking" will be done via the on-board GPS receiver, therefore no radar
transponder or range and range rate equipment is required. For the purpose of
ground based orbit determination, the on-board GPS receiver shall deliver at a
minimum [CONFIDENTIAL TREATMENT] minutes arcs of GPS data (on different orbits)
a day.
The spacecraft will have to respond to commands to switch devices on and off and
to set the state of redundancy switching, if any. The other commands will be to
the orbit acquisition thruster(s). Commands will be uplinked in packets to the
satellite in an identical manner as the packets to be directed onward to
subscriber terminals. The command system will contain a level of software
protection and command verification capability. A rudimentary command system
shall be accessible via the a subscriber uplink channel(s). This shall be
protected from intentional or unintentional unauthorized use. It is not
envisioned that any of the redundancy switching be automatic on the spacecraft.
Fault detection should cause the satellite to enter a known "safe" mode.
The spacecraft shall transmit a verification to the ground which indicates
whether a transmitted command was received by the satellite.
The spacecraft shall be capable of handling stored commands which will execute
at a predefined future time. Verification of the execution of these
time-triggered stored commands shall be stored in on-board software and
downlinked with backorbit data.
The spacecraft shall be capable of handling stored commands which will execute
at a predefined geographic location. This capability shall be as a minimum
command format containing a latitude/longitude point and a radius. The command
shall execute and be deleted whenever the distance from the current
sub-satellite point and the point stored in the command format is less than the
distance stored in the command format. Verification of the execution of these
time-triggered stored commands shall be stored in on-board software and
downlinked with backorbit data.
3.3.5 RESET PHILOSOPHY AND SEU CONTROL TECHNIQUES
The Contractor shall develop a rational, comprehensive, implementable philosophy
to deal with single event upset (SEU's) and microprocessor and DSP software
malfunctions. Techniques developed based on this philosophy will be presented to
ORBCOMM for approval prior to implementation.
3.3.6 Spacecraft Software
The satellites shall be capable of having operational software reloaded from the
ground to fix any bugs which are discovered in the flight software after launch.
The nominal time to upload
29
106
any one code segment shall not exceed [CONFIDENTIAL TREATMENT] to allow for
retries during a pass. During the code upload process, the satellite shall be
capable of entering a "safe" mode, with adequate functionality to allow uploads
over the next two orbits. To the greatest extent practical, software parameters,
as opposed to code, shall be partitioned into a separate smaller packet which
can be uplinked separately.
The spacecraft processors shall host customer furnished Satellite Network
Software. The Contractor-provided satellite software and operating system shall
interface with the Satellite Network Software as required to implement the
requirements of this document including:

3.4.2 INTERFACE TO NETWORK CONTROL CENTER MESSAGE PROCESSOR (MP)
There are two primary interfaces between the SCC and the remainder of the
ORBCOMM system: Satellites (via GESs), and NCC Network Management and Control.
3.4.2.1 SATELLITES
The links to the satellites, via the GESs, are built over BSD sockets. The MP
shall host a task to provide sequenced delivery of frames to/from the
satellites. This software will be provided by ORBCOMM.
3.4.2.2 NCC Network Management and Control Interfaces
This section describes the network management signaling between the SCC and the
U.S. NCC. There an primarily four types of communication between the two
systems:
1. The NCC must know the status of each satellite in order to
minimize queuing delays and reduce the possibility of
subscriber terminals driving the satellite receivers into
saturation.
2. The NCC must be able to obtain updated orbital elements in
order to accurately schedule the connections with the GESs.
3. The NCC shall provide a mechanism for the SCC to request
precedence tracking of a malfunctioning spacecraft.
4. The NCC shall provide the SCC operators with a schedule of
satellite connections.
The signaling from the SCC to the NCC is generally achieved using the TCP/IP
Simple Network Management Protocol (SNMP) agent process running on the SCC.
The SCC SNMP agent will be supplied by ORBCOMM and is accessible to SCC
processes by simple function calls.
3.4.2.2.1 SCC GENERATED SIGNALS/INFORMATION
THE SCC will send three signals to the MP: telemetry affecting network
through put, orbital elements, and tracking requests.
34
111
3.4.2.2.1.1 Telemetry Affecting Network Throughput
This telemetry includes, but may not be limited to, the status of satellite
transmitters and receivers, the nadir pointing vector, scheduled outages,
low-power conditions, etc. An SNMP variable is associated with each telemetry
dam point. and the value must be continuously updated and sent (via function
call) to the SNMP process running on the SCC. The SNMP process will contain
thresholds which indicate whether the value of the telemetry data point
constitutes an alarm condition. If an alarm exists, an alert is automatically
sent to the NCC.
3.4.2.2.1 Tracking Requests
The SCC shall be able to request a particular GES site to track a particular
satellite, priority track with a particular GES, or cancel a previous tracking
request by sending the appropriate signals to the SNMP agent. When priority
tracking a satellite, the NCC shall maintain a link with that spacecraft
whenever possible. When priority tracking with a particular GES, that GES will
be used for tracking whenever it has view of a satellite over any other GES with
a view of the same satellite. A later signal, also directed to the SNMP agent,
shall clear the condition.

1. INTRODUCTION AND OBJECTIVES
This Statement of Work (SOW) describes the tasks to be performed by OSC/Launch
Services Group (LSG) in providing three space launches for ORBCOMM Global's
Low-Earth orbit satellite communications program (the "ORBCOMM System"). A
fourth Pegasus launch is optional and shall contain all the tasks listed in this
SOW for the first three launches. The intent of this contract is for the OSC/LSG
to perform all tasks necessary to place OSC/SESG furnished payloads into the
required orbit as described in section 3.1.1 Mission Requirements. As set forth
herein, OSC/LSG shall furnish the necessary management, labor, facilities and
materials to manufacture, test, integrate, support, and launch three Pegasus
launch vehicles to place the OSC/SESG furnished payloads into the prescribed
orbit. Each launch includes the Pegasus XL Launch Vehicle, the Hydrazine
Auxiliary Propulsion System (HAPS), payload integration activities, mission
peculiar activities, all spare parts, maintenance activities, and the launch
operations needed in support of the Pegasus.
The launches supplied by OSC/LSG shall use an appropriate configuration of the
launch vehicle. The interface characteristics, environmental conditions to which
the payload is exposed and vehicle system requirements shall be described in an
Interface Control Document (ICD), which will be developed for the ORBCOMM
missions defined by this contract. The signed ICD shall supersede any
conflicting specifications set forth in this SOW.
2. GENERAL BACKGROUND
The ORBCOMM System is a constellation of at least 26 gravity gradient stabilized
satellites designed to relay VHF radio packets between ground users. Each launch
shall consist of eight satellites.

Table 3-3. Payload Acceleration Environment
Drop Transient Acceleration: Because of the oscillatory nature of the drop
transient response, significant dynamic amplification of the accelerations are
expected throughout the spacecraft. The payload mass distribution, stiffness,
and length of the primary structure greatly affect the amplification level. The
payload is responsible for translating these loads. To avoid dynamic coupling
of the Pegasus, the payload must be designed with a structural stiffness to
insure the first fundamental frequency of the payload is greater than 20 Hz.
OSC/LSG recommends that two coupled loads analysis, a preliminary and a
verification, be performed to validate the initial payload design loads.
3.1.2.3.2.2. Payload Vibration Environment

3. QUALITY ASSURANCE (QA) PROVISIONS
3.1 QA Responsibilities. QA personnel will ensure the QA requirements specified
in this TM are satisfied.
3.2 Failures and Retest. If a test discrepancy occurs, the test will be
interrupted and a Test Failure/Corrective Action Report (TF/CAR) will be
generated. The test configuration will not be disturbed without the approval of
the test engineer. If the discrepancy is determined to be due to the test setup,
software, or to a failure in the test equipment, the test being conducted at the
time of the failure may be continued after repairs are completed. If the
discrepancy is determined to be a failure in the item under test, the
appropriate corrective action will be completed before testing resumes.
The degree of retest will be determined for each case by the test engineer based
on the nature of the failure. After significant component rework, all previous
acceptance tests may be repeated. If the redesign or rework is very minor, a
functional test and the test the unit failed may be required. Testing done
previously will not be repeated except at the direction of the test engineer.

SCHEDULE 14 - PERFORMANCE WORKING SATELLITES
FOR ON-ORBIT INCENTIVE PAYMENTS
(a) The parties will negotiate achievement criteria prior to launch,
including the following criteria for a Working Satellite:
1. The subscriber receiver has at least [CONFIDENTIAL
TREATMENT] subscriber demodulators operating in all receiver
modes;
2. The subscriber downlinks are operating at no less than
[CONFIDENTIAL TREATMENT] dB below the specified RF power
level;
3. The gateway links are operational;
4. The Attitude Control System is operating to specification
for earth and sun pointing;
5. At least [CONFIDENTIAL TREATMENT] of the specified amount
of on-board memory is available for datagrams;
6. The orbit propagator is operating to specification; and
7. The power output from the solar cells is at least
[CONFIDENTIAL TREATMENT] of beginning of life specifications.
8. The system shall pass at least [CONFIDENTIAL TREATMENT] of
the specified message traffic rate; and
9. The power system shall support at least [CONFIDENTIAL
TREATMENT] of the specified transmitter duty cycle.
(b) In the event there are less than three (3)Satellites in any plane
that have GPS capability in accordance with applicable specifications, the
related On-orbit Performance Incentive Payments shall be reduced by
[CONFIDENTIAL TREATMENT] percent ([CONFIDENTIAL TREATMENT]%), provided that any
reduction for the fifth year shall be [CONFIDENTIAL TREATMENT] percent
([CONFIDENTIAL TREATMENT]).
(c) In the event that Working Satellite Criteria are not fully met, but
the plane of Satellites is usable to ORBCOMM Global, Orbital shall be entitled
to payment for partial success in an amount to be determined by negotiation of
the parties based on the revenue generating capability of the plane of
Satellites.
221
(d) The parties shall review the success criteria during the pre-launch
phase of the program and shall conduct good faith negotiations for any
appropriate modifications to the criteria.
