Trek Resources, Inc. is an independent energy company that is engaged in the exploration, development, exploitation and acquisition of on-shore oil and natural gas properties in conventional producing areas of the United States. We originally incorporated our company in the State of Utah in 1983 under the name of Quasar-Tech, Inc. From 1983 until 1992, we engaged in various types of business activities, including the manufacture of oil and natural gas recovery equipment. In 1992, we concentrated our efforts in the production of oil and natural gas when McGowen Oil & Gas Company, Inc., a Texas Corporation, merged with Quasar-Tech, at which point we changed our name to McGowen Resources Company, Inc. We continued operations under this name until June 2000, when we changed our name to Trek Resources, Inc. Recently, we merged with and into a wholly owned subsidiary in order to change our state of incorporation from Utah to Delaware. We conduct our primary operations in Oklahoma and Texas and also own non-operated interests in New Mexico. To date, we have grown almost exclusively through the acquisition of producing properties and prospects. Our Corporate offices are located in Dallas, Texas.
