The Company’s first product, PoNS, is an authorized class II, non-implantable medical device authorized for sale in Canada. PoNS is intended as a short term treatment (14 weeks) of gait deficit due to symptoms from multiple sclerosis (“MS”) and balance deficit due to mild-to-moderate traumatic brain injury (“mmTBI”) and is to be used in conjunction with physical therapy (“PoNS Treatment"™). It is an investigational medical device in the United States, the European Union (“EU”), and Australia (“AUS”), and it is currently under review for clearance by the FDA for use in gait dysfunction due to MS and AUS Therapeutic Goods Administration. PoNS Treatment™ is not currently commercially available in the United States, the EU or Australia. 2

The first and only patented treatment combining trigeminal nerve neurostimulation via the tongue with physical therapy to reduce symptoms of neurological disease or trauma.

CHINA: Strategic Agreement with China Medical Systems (“CMS”) for development and commercialization of PoNS in China plus 4 territories  Transferred ownership of Asian patents, patent applications and granted exclusive license to market, promote distribute and sell the technology CMS assumed all development, patent (both application and defense), future manufacturing, clinical trial, and regulatory clearance costs for the territories Upon clearance in the U.S., CMS can use relevant documentation used for U.S. approval to apply for Chinese approval AUSTRALIA: Awaiting decision from Therapeutic Goods Administration (TGA) International Strategy 23

795k US individuals have a stroke each year1 50% of stroke survivors 65 and over suffer from reduced mobility2 Walking is the most frequently reported activity at the time of a fall in stroke survivors3 In post-stroke patients, the cerebral cortex becomes impaired while the spinal cord is preserved. The ability to generate information from the spinal cord required for walking can be utilized through specific movements to reorganize the cortex (neuroplasticity) Falls are the leading cause of injury related deaths among elderly people in the U.S. Next Neurological Market Opportunity Stroke Center for Disease Control and Prevention: Stroke Facts “Walking Adaptability after a Stroke and Its Assessment in Clinical Settings”; Stroke Res Treat.; August 28, 2014 Verma R, Arya KN, Sharma P, Garg RK: Understanding gait control in post-stroke: Implications for management.
