Hemisphere GPS and Summit Liability Solutions Sign Agreement to Provide Customized Outback S3 System

Calgary, AB — August 12, 2010 — (TSX: HEM) Today, Hemisphere GPS announced a multi-year agreement to supply S3-S Navigator™ – a customized Outback S3 precision guidance system for Summit Liability Solutions (Summit). S3-S Navigator uses Hemisphere GPS’ Crescent™ GPS receiver technology in combination with Hemisphere GPS eDriveTC™ for tilt control to precisely apply drilling fluids to a disposal area and is designed to eliminate most of the human error currently present in drilling waste disposal services.

With Summit direction and logic, Hemisphere GPS modified the popular Outback S3 to interface with the Summit Earth™ system. Summit Earth is a Summit-designed web-based data entry platform with built-in satellite imagery, regulatory compliance checking and self-auditing capabilities, and powerful reporting functionality. Spatial information from Summit Earth is uploaded into S3-S Navigator and, once armed, the system controls the discharge valve of a disposal unit based on regulatory parameters entered by Summit’s field technicians. The custom software of S3-S Navigator provides visual reference and guidance of the disposal operations. Upon completion of a job, spatial information collected in real time is downloaded from S3-S Navigator and uploaded into Summit Earth where the final report is produced and the true disposal area is overlaid onto satellite imagery. S3-S Navigator provides on/off boundaries to keep the waste disposal within a given area and automatically turns the discharge system on and off when the vehicle reaches the set boundaries. eDriveTC provides S3-S Navigator with details of the vehicle’s slope to prevent runoff and pooling of drilling fluids by limiting disposal on restricted terrain and enables either pitch or roll measurements to be taken. Field notes can be utilized and the system is designed to convert log files into useable file formats for use in Summit Earth and or Google Maps.

"Our partnership with Summit illustrates the suitability of S3 to new markets," says Dan Cookro, Director of Business Development, for Hemisphere GPS Precision Products. "The S3 is a complete agricultural precision guidance system that we can customize to meet specific needs. This avenue of growth further demonstrates our ability to provide real-world custom solutions."

Summit Liability Solutions Inc. is the exclusive partner with Hemisphere GPS as Summit will market and support S3-S Navigator as an integral part of their comprehensive drilling waste management system.

"The Oil and Gas industry was long overdue for a technological advancement to reduce non-compliant activities associated with drilling waste disposal in North America," stated Russel Orcutt, President of Summit Liability Solutions Inc. "Our partnership with Hemisphere GPS has resulted in a dramatic game changing solution that manages the ever-increasing regulatory pressure to be environmentally compliant."
