There are approximately five dominant defense contractors in our industry. They include Lockheed Martin, General Dynamics, Northrop Grumman, Harris Corporation and ITT Corporation. They have been able to successfully launch their products, and penetrate the marketplace. While we hope to design and market products that are competitive with those offered by these contractors, there is no assurance that we will be able to do so. Unless we are able to persuade government agencies that we have products superior to those of these dominant defense contractors, we will be unable to generate sufficient sales of our products to continue to be successful. Further, these contractors have numerous contracts within the government and its agencies, who may be unwilling to switch their buying habits to our Company.
