DFW HOMELAND SECURITY ALLIANCE BUILDS A TEAM OF COMPANIES

TO BRING NATIONAL SECURITY HOME TO TEXAS

Richardson, TX - The Dallas Fort Worth Homeland Security Alliance (DFWHSA) announces the formation of a partnership represented by Dallas Fort Worth (DFW) Metroplex companies and agencies to pursue Homeland Security contracts with HiEnergy Technologies, Inc., an entrepreneurial California based sensor and detection technology company. The DFWHSA and Lockwood Greene, who are leading the initiative, view this project with HiEnergy as a business model template forerunner for future successful partnerships where companies combine their expertise to create and expand profitable business markets. The goal of this project is to establish manufacturing and business channel opportunities in the DFW area for HiEnergy's products.

"Each member of the project was carefully selected to participate based on their marketing, business experience and technology strengths," notes Executive Director for the DFWHSA, Susie Dodson. "The project required the combined expertise of each of the participating companies and organizations to entice HiEnergy to consider manufacturing their commercial explosive and chemical detection product within the DFW Metroplex."

HiEnergy's technology and applied applications are state-of-the-art. The commercialization of the technology that has been tested and produced will allow the partnership to consider marketing the product to a variety of industries such as transportation security including land, sea and air, agricultural and biomedical. Each participating member will work with HiEnergy, federal and state officials and the DFWHSA to bring this project to fruition. The benefits of this type of business model include economic development and tax revenue for the state of Texas, the creation of jobs, the development of Homeland Security solution products and the building of partnerships between companies that share loyalties to the same municipalities and regions while developing their business growth strategies.
