Risk Factors ■ The size and future growth in the market for our Ubiquitor device or our PLC technology under development has not been established with precision and may be smaller than we estimate, possibly materially. If our estimates and projections overestimate the size of this market, our sales growth may be adversely affected. ■ Since wireless networks are susceptible to interference and other limitations, and one advantage of our Ubiquitor device and our USIP platform is that it can connect to wireless networks as one way to transmit data, wireless network limitations may reduce the competitive advantage of the Ubiquitor and USIP platform in the marketplace. ■ Demand for our products is uncertain and depends on our currently unproven ability to create and maintain superior performance. ■ There is a risk that the market will not adapt to using the smartphone readout as a substitute platform for sensor devices, causing our products to fail in the marketplace. ■ Our growth strategy includes licensing our intellectual property, and we run the risk that a licensee could become a competitor. ■ Our Ubiquitor device greatly depends on the growth and adoption of the IoT market, and other next - generation internet and smartphone - based applications. ■ Prices and availability for the electronic parts and plastics we need to assemble the Ubiquitor could fluctuate. ■ Our potential inability to adequately protect our intellectual property during the outsource manufacturing of our filtration products in China could negatively impact our performance. ■ We outsource our product manufacturing and are susceptible to problems in connection with procurement, decreasing quality, reliability and protectability ■ Internal system or service failures, including as a result of cyber or other security incidents, could disrupt business operations, result in the loss of critical and confidential information, and adversely impact our reputation, our business, financial condition, results of operations and cash flows. Our connected products potentially expose our business to cybersecurity threats. 3
