X-CHANGE CORPORATION DELIVERS SURFACE ACOUSTIC WAVE (SAW) TAG TECHNOLOGY FOR THE OIL AND GAS
INDUSTRY

DALLAS, March 13, 2008 — The X-Change Corporation (OTCBB: XCHC) through its wholly owned subsidiary, AirGATE Technologies, Inc. announced today, its completion of Surface Acoustic Wave (SAW) tag technology based on Radio Frequency Identification (RFID) for the oil and gas industry.

SAW tags and readers will be used for monitoring drill pipe and other down hole tools. The tags are inserted into drill pipe to determine the pedigree, asset and inventory in down-hole drilling environments. The tags and readers can survive the lifetime of the pipe or tool.

Kathleen Hanafan, President and COO, stated “these tags and readers are unique because they have been developed and packaged specifically to withstand temperatures up to 300°C and pressures up to 20,000 psi with a long read range that is needed in the oil and gas fields. We expect our tagging system to be the ‘standard’ in the oil and gas industry.
Presently there are no other tags able to withstand the temperatures, gases, pressures and other extreme environmental factors that are experienced in down-hole drilling conditions for long periods of time.”
