Forward Looking Statements!This presentation may contain forward-looking statements that are based on our current expectations, estimates and projections about our industry as well as management's beliefs and assumptions. Words such as "anticipates," "expects," "intends," "plans," "believes," "seeks,” "estimates," "may," "will," and variations of these words or similar expressions are intended to identify forward-looking statements. These statements include projections about the growth of the market for aesthetic procedures, and speak only as of the date hereof. Such statements are based upon the information available to us now and are subject to change. We will not necessarily inform you of such changes.!
These statements are not guarantees of future performance and are subject to certain risks, uncertainties and assumptions that are difficult to predict.

Significant Market Opportunity!
Progress!
• One-time, subretinal injection offers “functional cure” of wet AMD !
• AAV2 vector containing gene encoding sFlt-1, a naturally occurring VEGF inhibitor, administered directly to retina cells!
• Well tolerated with no drug-related adverse events!
• Subjects gained/maintained vision with no or minimal need for additional treatment over one year!
• Wet AMD is a leading cause of vision loss that affects three million people worldwide with over $6B sales !
• Compliance with existing treatments is challenging and longer-lasting treatment is a major unmet need!
• Phase 2a trial fully enrolled in Australia; data expected mid-2015!
• Phase 2b in the U.S. planned for 2H-2015!
Poor Compliance Leads to Progressive Vision Loss!
