Application for Special Temporary Authority
File No. 1223-EX-ST-2015

                  PURPOSE OF STA AND FREQUENCY COORDINATION

The purpose of this STA is to further test an automobile racing communications system for voice
that is in the developmental stage. The tests, one in a series by the Audi racing team, will occur
at a single racing venue at Sebring, Florida during the period December 6 to 12, 2015. The
system will be deployed by the Audi LMP race team. The race team will use the communications
system on a developmental testing basis on behalf of and overseen by MRTC Motorsport
Communications.

The venue during December, 2015 when this system will be deployed are as follows:

Sebring, FL Raceway: December 6-12, 2015 inclusive.

This request is virtually identical to STAs granted at this venue in 2014 and earlier this year. See,
WH9XID and WI9XHA (File No. 0121-EX-ST-2015). Most of the channels requested are
identical as well.

The applicant requires for this venue five VHF frequency pairs as specified in this application in
the range 167/172 MHz for duplex voice operations, and one simplex channel in the VHF range.

The applicant has consulted the ULS database with respect to the VHF channel ranges sought
and proposes what are believed to be unoccupied channels in the area of the Sebring Raceway. In
the event of any interference reported, operation on any or all of these frequencies will cease
until a solution satisfactory to the licensee is reached.

The “stop buzzer” contact on behalf of the applicant is Mr. Steve Harris, who can be reached at
+44 (0) 7973391410. If a United States contact number is required, undersigned counsel can be
reached at any time at (301) 351-3795 and will handle all stop buzzer requirements.

All other inquiries can be addressed to undersigned counsel:
