Sharewell Has Completed a Majority Recapitalization with White Deer Energy

HOUSTON, April 5, 2012 — GulfStar Group (“GulfStar”) is pleased to announce the majority recapitalization of Sharewell, L.P. (“Sharewell” or the “Company”) by White Deer Energy L.P. (“White Deer”). GulfStar served as exclusive financial advisor to Sharewell throughout the transaction, which closed on March 29, 2012.

Sharewell is a recognized leader in providing directional services, equipment and technology to the oil and gas industry, offering complete, project-specific, directional and performance drilling systems from one quality source. Sharewell’s proprietary Electro-Trac™ EM MWD System is industry-leading technology ideally suited to facilitate measurement-while-drilling, well-logging, and other real-time downhole operations associated with oil and gas exploration. The Company employs this technology in providing directional drilling services. These services supply a full range of professionals and equipment required to plan and execute the directional drilling segment of a wellbore, including directional drillers, measurement-while-drilling equipment and drilling motors.

Todd Caspary, Sharewell CEO, said, “Sharewell has developed an EM system that performs better than any other comparable systems and saves time and money for the customer. This technology combined with our outstanding and expanding directional drilling services will fuel our growth. We are pleased to partner with White Deer, who has the industry experience to assist us as we continue to grow our business. We could not have chosen a better partner.”

The GulfStar Group transaction team included Managing Director Cliff Atherton, Managing Director Kent Kahle, Senior Vice President Pam Reiland, Associate Chase Stanzel and Analyst Patrick Stefan. “GulfStar is proud of its long-term relationship with Sharewell. We have advised Sharewell’s management as they grew Electro-Trac™ from a prototype in 2007 to full commercialization in 2008. At the same time, they expanded Sharewell’s service capability in the directional drilling market,” said Cliff Atherton. “Sharewell’s partnership with White Deer, a leader in private equity for the energy industry, will be a powerful combination in the industry,” said Kent Kahle.

Jamie Saxton, Partner of White Deer, commented, “Sharewell has developed an outstanding reputation based on performance and customer service, and Todd Caspary has assembled an impressive team.
