Recent Developments

The Grant Acquisition.   On September 8, 2006, we completed the acquisition of all of the issued and outstanding capital stock of Grant Geophysical, Inc. and its subsidiaries (“Grant”) for $125,000,000 in cash, subject to adjustment for net debt and working capital. Headquartered in Houston, Texas, Grant performs two dimensional and three dimensional seismic surveys in the land, transition zone and shallow water environments in the United States, Western Canada, Central and South America, Africa, the Middle East, Australia/New Zealand and the Far East using both analog and digital seismic equipment for a wide range of customers exploring for oil and natural gas reserves. Through the Grant acquisition, we also added equipment that complemented and expanded our operational capabilities. Grant has long-standing relationships with its customers, which include national oil companies, major international oil companies and smaller independent exploration and production companies around the world. Additionally, Grant has a very experienced senior management team with vast international experience working in land, transition zone and shallow water environments.

The Trace Acquisition.   On December 1, 2005, we completed the acquisition of all of the issued and outstanding common shares of stock of Trace for CDN $35,000,000, which we paid in cash and by assuming certain existing indebtedness of Trace, subject to certain adjustments, and 100,000 shares of common stock. Headquartered in Alberta, Canada, Trace provides seismic services to exploration and production companies in the oil, gas, and mining industries, and it specializes in the acquisition of land-based seismic surveys in North America. Trace is a leader in the market for next generation full-wave (multi-component) seismic technology. Through this acquisition, we have and will continue to expand our business into the Canadian Arctic, California and the Appalachian Mountain region. Trace is the only major contractor operating in California and the largest seismic contractor operating in the Appalachian Mountains region. These areas provide us with new business opportunities as well as the potential for long-term growth within each respective market.
