1. Company & Technology Overview The QuadraSonic Array is Built, Patented & Proven

2. Executive Summary QuadraScan Technologies has developed a patented* technology that targets a significant quality, production and manufacturing related problem, leak detection and location. This solution can be utilized in diverse industries; QuadraScan is currently working with the global automotive and consumer appliance industries. The Problem detection of intrusions, leaks and/or build variation is an integral part of Quality Control (QC). Manufacturers have traditionally relied on test processes utilizing water, which is potentially damaging, costly, and raises environmental and plant safety issues. Often the data is subjective, time consuming and only done on a select few units. Traditional subjective noise evaluation is not only time consuming, but relies on favorable ambient conditions to conduct the testing, and can only be performed on a select few vehicles. The Solution, the QuadraSonic Array TM identifies and locates intrusion points and/or build variation in a non-destructive fashion. Our technology utilizes ultrasound to test the “sealed effectiveness” of closed compartments. This technology provides an accurate, repeatable, and unbiased data instrument empowering the manufacturer to adopt a quantitative scale of measurement The QuadraSonic Array is Built, Patented & Proven * patent #6983642

3. What The Array Does… Tests for Intrusions –The QuadraSonic Array utilizes ultrasound energy to test the “sealed effectiveness” of all types of closed compartments. Detects build variation –Providing quantitative data during the design phase of new makes and models and variations during production. Objective comparison of supplier components –Focus on “Sealed Effectiveness” Creates an archived “UltraSound Fingerprint” –Can be used in analysis of quality standards and referenced in the case of future warranty problems Provides for real-time and remote quality test audit –All information archived

4. The Benefit The Array will provide an immediate return on investment by; –Enhancing the plants quality control process –Reducing wind and water related after-market warranty costs –Opening valuable plant floor space. –Eliminating water test maintenance costs. –Eliminating rework due to water testing. –Eliminating water and chemicals; thus having a positive impact on environmental and safety standards
