4. The TSR assumes $100 was invested in the Company for the period from the beginning of the measurement period through the end of the listed measurement period. The TSR is calculated by dividing (i) the difference between the stock price at the end of each measurement period shown and the beginning of the measurement period by (ii) the stock price at the beginning of the measurement period. Historical stock performance is not necessarily indicative of future stock performance.

5. At this time, given that we are a research and development company without revenue, we do not use any specific company-selected financial measures for purposes of determining “Compensation Actually Paid.” As is the case with many companies in the biotechnology industry, our annual incentive objectives are generally tied to our clinical, program and regulatory metrics rather than financial goals. Accordingly, we do not have a financial metric in our executive compensation program that would constitute the Company Selected Measure, as contemplated under the SEC Pay Versus Performance disclosure rules, particularly as the pay versus performance table includes our TSR performance which is linked to the value of the equity awards held by our NEOs.

Description of Relationship Between the CAP to PEO and Non-PEO NEOs and the TSR

The following chart sets forth the relationship between the CAP to our PEO, the average of the CAP to our Non-PEO NEOs, and our cumulative TSR and Peer Group TSR over the five most recently completed fiscal years.
