Exhibit A I. Description of Application Walgreen Co. (“Walgreens”) hereby requests Special Temporary Authority (“STA”) to operate its VSAT system, licensed under call signs E880547 pursuant to modified parameters described in this exhibit. Walgreens respectfully requests that the Commission act on this STA request on an expedited basis. Swift grant of this STA request will allow continued operation of the Walgreens VSAT network, an important part of our ability to communicate with the more than 8000 participating retail locations that make up the Walgreens family of retail pharmaceutical locations and related health care participants. Due to the acquisition of some RiteAid locations, Walgreens is making the following changes to its facilities A. Addition of a New Model .98 Meter Antenna Walgreens respectfully requests addition of a new model .98 meter antenna. The 98 cm Prodelin antenna is a well-established Hughes product which has been approved for deployment on many US licensed satellites (SES-MOD-20061020 01873 for Callsign E920495), but which does not comply with §25.209 of the FCC’s Rules. The main lobe for the antennas is slightly wider than the performance mask in §25.209 and as a result the antenna only complies the FCC’s mask from 1.6 degrees onwards. Prodelin Model Number: 9008668 Diameter: .98M Number of Units Requested: 1500 Area of Operation: CONUS, PR, AK, HI, and VI 1. Particulars of Operation: Max Frequency Max EIRP Polarization Emission T/R Mode EIRP/ Modulation/Services (GHz) Density Carrier 11.7-12.2 H, V 12M0G7D R PSK, DATA, 10 MSPS 11.7-12.2 H, V 36M0G7D R PSK, DATA, 30 MSPS 11.7-12.2 H, V 1M23G7D R PSK, DATA, 1024 KSPS 14.0–14.5 H, V 307KG7D T 44.3 27.3 PSK, DATA, 256 KSPS 14.0–14.5 H, V 1M60G7D T 44.3 27.3 PSK, DATA, 1024 KSPS Max Gains: 39.9 dBi at 11.950; 41.3 dBi at 14.250 Max total input power at antenna flange: 2.0 watts Max aggregate output EIRP for all carriers: 44.3

2. Radiation Hazard Analysis A radiation hazard analysis was done for a Prodelin 98 cm antenna and 2 Watts of power applied at the flange, using the methodology from OET Bulletin 65. The results of this analysis, which can be seen in Exhibit B, show that the maximum permissible exposure limit (MPE) for protection of the general public of 1 mW/cm2 is met in the near, transition, and far field as well as in the region between the reflector and the ground. However, as is typical for all satellite antennas, the value of 1 mW/cm2 is exceeded in the volume of space between the feed horn and the reflector. This region is not usually accessible to the general public because the units are typically installed on rooftops. As a further protection mechanism, all VSAT terminals are equipped with an automatic shut-off mechanism which disables the transmitter should the receive signal be lost. This mechanism shuts the transmitter off within milliseconds should the receive carrier be blocked.
