Each Investor Warrant is exercisable for 0.75 of a share of the Issuer’s Common Stock. The Investor Warrants are immediately exercisable and expire five years from the date of issuance. Tang Capital Partners may not exercise any portion of the Investor Warrants for shares of Common Stock if, as a result of the exercise, Tang Capital Partners, together with its affiliates and any other person or entity acting as a group, would own more than 9.99% of the Issuer’s outstanding shares of Common Stock after exercise. However, Tang Capital Partners may increase such percentage to any other percentage, not in excess of 19.99% (to the extent such limit is required under applicable Nasdaq rules), by providing written notice to the Issuer, provided that any increase in such percentage shall not be effective until 61 days after notice is provided to the Issuer.

 

 

Each Pre-Funded Warrant is exercisable for one share of the Issuer’s Common Stock and is immediately exercisable.

However, Tang Capital Partners may increase such percentage to any other percentage, not in excess of 19.99% (to the extent such limit is required under applicable Nasdaq rules), by providing written notice to the Issuer, provided that any increase in such percentage shall not be effective until 61 days after notice is provided to the Issuer.
