DECLARATION OF ORBIT COMMUNICATION LTD Model “AL-7108” (C-Band) I, Buy Naym, Director R&D Satcom Systems, hereby declare, that the following statements are true and correct: 1. Orbit Communication Ltd. Designs, develops and manufactures marine stabilized antenna systems for satellite communications at sea. 2. The Model “AL-7108” (C-Band) meets the shape of the off-axis EIRP spectral density mask provided for in 47 CFR Section 25.221. 3. Anyone using the Model “AL-7108” (C-Band) antenna will comply with U.S. Federal Communications Commission (FCC) off-axis EIRP spectral density limits provided that, the transmit power density at the antenna input is kept below -9.9 dBW/4KHz (0.102 Watts/4KHz) of occupied bandwidth (the worst case is at 6.4 GHz X-Pol). 4. Orbit Communication Ltd “AL-7108” (C-Band) Marine Stabilized System will maintain a stabilization tracking accuracy of better than 0.2 degrees under specified ship motion conditions. The internal controller software continuously monitor the instantaneous antenna tracking error and will cease the Tx of the BUC within 100ms (using M&C of the BUC) if an unexpected even occurs that causes the tracking error to exceed 0.5 degrees. Transmissions will not restart until the tracking error is less than 0.2 degrees of the target satellite.

5. Orbit Communication Ltd maintains all relevant test & analyzed data, which is available upon request. Executed on December 13, 2011 Guy Naym Director R&D SatCom Systems Orbit Communication Ltd
