2. Upon the closing of the IPO the Warrants to purchase Series A Preferred Stock automatically converted on a 6.986-for-1 basis into Warrants to purchase Common Stock, and the exercise price automatically adjusted to $6.99 per share, pursuant to the terms of such Warrants. This transaction is reported on Form 4 solely for the purpose of reflecting such changes.

3. The Warrant is immediately exercisable.
