Exhibit B – Orbital Debris Assessment Report (“ODAR”) SWARM Orbital Debris Assessment Report SWARM TECHNOLOGIES MISSION PROFILE PREPARED BY: SWARM TECHNOLOGIES INC REVISION ​1​, May 21, 2018 ODAR Signature Approval Program/ Project Sara Spangelo Manager Signature Date May 21, 2018 ODAR Section 1: Program Management and Mission Overview Program/ Project Sara Spangelo Manager Mission Description This mission is a technology demo for two-way communications satellites, and data relay. Foreign Government None Involvement Project Milestones The project milestones for the Swarm satellites align with the launch of the vehicles into orbit, including a delivery of the spacecraft one month prior to launch of the SpaceX SSO-A mission. Proposed Launch September 1, 2018 Date: Proposed Launch Electron Vehicles Number of Satellites: 3 Altitude: 575 km SSO Period: 95 min Proposed Launch Vandenberg Air Force Base, CA, United States Sites

Launch Vehicle SpaceX Operator: Mission Duration: The operational lifetime of the hardware and electronics for each satellite is designed to be up to​ 10 ​years following deployment from the launch vehicle. The orbital lifetime for the satellites is expected to be between 5.​3 to 9.3 year​s, depending on the vehicle’s orbit and solar influence of the Earth’s atmosphere, as described in Section 6. Launch / Launch Deployment Profile: The Swarm satellites will be injected directly into the target orbits outlined in the table above. Checkout For up to 1 month following deployment into orbit, the Swarm satellites will remain in checkout phase. During this phase, ground operators will verify correct operation of the satellite and its payloads, and prepare it for the operational phase. Operations The operational phase of the satellite begins following the successful deployment of the Swarm satellites from the launch vehicle and successful checkout. Post-mission Disposal Following the end of the operational phase, the satellites will remain on orbit in a non-transmitting mode​ while the ​orbit of the satellite passively decays until the satellite reenters the atmosphere and disintegrates. The satellite is nominally expected to reenter the atmosphere 5.3 y​ears following deployment from the launch vehicle, as detailed in Appendix B: Swarm Satellites Orbit Lifetime. Selection of Orbit: The selection of the chosen orbit was made due to available launch opportunities. Potential Physical As the satellite does not have any propulsion systems, its orbit will naturally Interference with decay following deployment from the launch vehicle. Other Orbiting Object: ​ n 5, the probability of physical interference between the As detailed in Sect​io satellites and other space objects is sufficiently unlikely that the satellite complies with Requirement 4.5.

ODAR Section 4: Assessment of Spacecraft Intentional Breakups and Potential for Explosions Potential causes for spacecraft breakup (there is only one plausible causes for breakup of the satellites): ● Energy released from onboard Lithium-ion battery from the unlikely event of overcharging or shorts Summary of failure modes and effects analysis of all credible failure modes which may lead to an accidental explosion: The battery aboard the satellite is a 12.5 Whr Lithium-Ion battery, which represents the only credible failure mode during which stored energy is released. The main failure modes associated with Lithium Ion batteries result from overcharging, over-discharging, internal shorts, and external shorts. The battery onboard Swarm satellites complies with all controls / process requirements identified in JSC-20793 Section 5.4.3 to mitigate chance of any accidental venting / explosion caused by the above failure modes. Detailed Plan for any designed spacecraft breakup, including explosions and intentional collisions: There is no planned breakup of the satellites on-orbit. List of components passivated at EOM: At end of mission, all radio transmissions and beacons will be disabled. Spacecraft transmissions are only initiated by ground command and self terminate. All RF transmissions from the satellite can be disabled via command from the ground. Rationale for all items required to be passivated that cannot be due to design: N/A Assessment of spacecraft compliance with Requirements 4.4-1 through 4.4-4: 4.4-1, Limiting the risk to other space systems from accidental explosions during COMPLIANT deployment and mission operations while in orbit about Earth or the Moon 4.4-2, Design for passivation after completion of mission operations while in orbit COMPLIANT about Earth or the Moon

4.4-3, Limiting the long-term risk to other space systems from planned breakups: COMPLIANT There are no planned breakups of any of the satellites. 4.4-4, Limiting the short-term risk to other space systems from planned breakups COMPLIANT There are no planned breakups of any of the satellites. ODAR Section 5: Assessment of Spacecraft Potential for On-Orbit Collisions Probability for Collision with Objects >10cm: The probability of a collision of any of the satellites with an orbiting object larger than 10cm in diameter was sufficiently small that the simulation performed using DAS 2.1.2 software returned a probability value of 0. Assessment of spacecraft compliance with Requirement 4.5-1 and 4.5-2: 4.5-1, Probability of Collision with Large Objects: COMPLIANT 4.5-2, Probability of Damage from Small Objects: COMPLIANT A DAS 2.1.2 log demonstrating the compliance to the above requirements is available in Appendix A – “DAS 2.1.2 Log”. ODAR Section 6: Assessment of Spacecraft Post-mission Disposal Plans and Procedures Description of Disposal Option Selected: Following its deployment, the satellite’s orbit will naturally decay until it reenters the atmosphere. Table 1 describes the mission scenarios for which lifetime analysis of Swarm satellites was considered, and the effective area-to-mass ratio of the satellite in each scenario. The ratio was calculated using the external dimensions of the satellite and deployed arrays. The satellites will be deployed from the P-POD with a spring and will separate from one another with ​separation springs in the feet. Drag area from deployed antennas (2x ​446mm whip antennas) was neglected; as such, the effective area-to-mass calculated below is a conservative case. Table 1 - Area-to-Mass Ratio of Swarm Satellites in Various Mission Scenarios Scenario Description Effective Area-to-Mass (m​2​/kg) Operational, Nominal ● Satellite maintains +Z axis nadir 0.025183​* (max) ● Satellite maintains position 0.010838*​ (min) around Z axis as planned for

Further, each of our satellites has an onboard GPS receiver, and the GPS location of each of our satellites is transmitted every time that the satellite is interrogated from the ground. We will have the ability to silence all RF transmission of the satellite by command from the ground. Our GPS data, and computed TLEs, will be provided to JSpOC, and any other entity that wishes to receive the live telemetry. The GPS device will provide telemetry for the hardware lifetime of the satellite, which exceeds the anticipated orbital lifetime of the satellite.
