Dear Paul:
I am pleased to extend to you an offer of employment with Tigercat Pharma, Inc. (the "Company"), in the position of Chief Medical Officer.
Salary. Your initial base salary will be $350,000 per year, less applicable withholdings. Your salary will be reviewed from time to time by the Board of Directors or its compensation committee, and may be adjusted in the sole discretion of the Board of Directors or its compensation committee.
Bonus.The Company will establish, in cooperation with you, objectives for your activities annually. The Company will evaluate your achievement of those objectives annually and you will be eligible for an annual bonus of up to 30% of your base salary.

After the start of your employment with the Company, the Board of Directors will grant you an option to purchase shares of Common Stock of the Company representing 1.4% of the fully diluted shares outstanding of the company pursuant to the Company's 2011 Stock Incentive Plan (the "Plan"). The exercise price of such option will be the fair market value of the Company's Common Stock on the date of grant, as determined by the Board of Directors based on an independent valuation intended to satisfy the safe harbor requirements of Section 409A of the Internal Revenue Code. The options shall vest with respect to 25% of the total number of shares on the one-year anniversary of your start date, and thereafter with respect to 1/48th of the total number of shares on each monthly anniversary of your start date.

Regs. Section 1.409A-l(h), and as amplified by any other official guidance.
