About Zosano Pharma

Zosano Pharma Corporation is an emerging CNS company focusing on providing rapid symptom relief to patients using known
therapeutics and altering their delivery profile using the Company’s proprietary intracutaneous delivery system. The Company’s goal
is to make intracutaneous drug delivery a standard of care for delivering drugs requiring fast onset of action. Zosano Pharma has
developed its proprietary intracutaneous delivery system to administer proprietary formulations of existing drugs through the skin
for the treatment of a variety of indications.  The Company believes that its intracutaneous delivery system offers rapid and
consistent drug delivery combined with ease of use. The Company is focused on developing products that deliver established
molecules with known safety and efficacy profiles for markets where patients remain underserved by existing therapies. Zosano
Pharma anticipates that many of its current and future development programs may enable the Company to utilize a regulatory pathway
that would streamline clinical development and accelerate the path towards commercialization. Learn more at www.zosanopharma.com.
