. For small, confined spaces or private spaces in the mall, such as bathrooms, employee only offices, or kitchens where the O -RXrobots may not be programmed to enter, TreX can instead be stationed as a portable disinfection unit. ____________ 2 https://ec.europa.eu/health/ph_risk/committees/04_sccp/docs/sccp_o_031b.pdf 100 AirGuard — Air Disinfection Solution AirGuard is designed to clean and disinfect indoor airflow using our UV -CLED technology. AirGuard’s UV -CLEDs modules are integrated within the HVAC systems, such as air conditioning units and ventilation ducts. These modules are able to inactivate airborne viruses and bacteria through ultraviolet germicidal irradiation (“UVGI”), disinfecting the air circulated indoors as it flows through the HVAC system. The modules have been lab tested to achieve a 99.9% disinfection efficacy within an 8 foot range, while a typical industry HVAC duct is no longer than 2 feet in length. The AirGuard system is designed to be compact and easy to install in most HVAC systems, with minimal modification required. The system is further customizable with options for additional sensors to monitor temperature, airflow, and overall air quality. Each AirGuard module’s physical dimensions are as follows: height: 1.8 inches, width: 1.2 inches, length: 8.5 inches, weight 10.6 oz. O-RX — UV-C LED Disinfection AMR In response to the COVID -19pandemic, Otsaw pioneered the world’s first incorporation of UV -CLED technology within an AMR: the O -RX. This combination is a powerful tool to combat the spread of COVID -19and other pathogens. Leveraging on our highly scalable software and hardware platforms, the development of the O -RX, from conceptualization, design, materials procurement, prototype testing to certification, was completed in eight weeks. We successfully launched the final model of O -RXin June, 2020, three months after the World Health Organization (“WHO”) declared COVID -19a global pandemic. As the testament to its high safety standards and product quality, the O -RXhas undergone rigorous testing under various conditions and has been certified by TÜV SÜD, an internationally -accreditedvehicular inspection and product certification services company. O -RXis a fully autonomous disinfection UV -CLED robot. It combines our UV -CLED
