HOUSTON, TEXAS (Thursday, March 20, 2014). Texadian Energy Inc., a wholly owned subsidiary of Par Petroleum Corporation (OTCQB: PARR), announced today that it has reestablished its presence in Calgary, Alberta, and will be opening a new office in coming weeks to function as the headquarters of Texadian Energy Canada Limited (TECL). Herb Hamilton, a long-time industry veteran and previous President of TECL, will rejoin Texadian as President of TECL. In addition to Herb, Erin Jones, TECL’s previous Operations Manager will also rejoin TECL as Vice President.

“We are thrilled to have Herb and Erin back on the Texadian team and look forward to working with them to grow our Canadian business”, said Peter Coxon, Chief Operating Officer of Par Petroleum and President of Texadian Energy. “We continue to believe there are tremendous opportunities for Texadian in Canada. In addition, our refining business in Hawaii, Hawaii Independent Energy, will benefit from our increased ability to source Canadian crudes.”

“Erin and I are excited about the prospects for reopening Texadian’s Calgary office. Canada’s fast growing energy complex provides an exciting backdrop for growing our business here. We are also excited to be able to support PAR’s refining operations.”

TECL will focus on supply and logistics opportunities that move Canadian crudes to demand markets as well as investment in infrastructure.
