Explanation of Responses:

( 1 )These shares of common stock and these common warrants were acquired directly from Tricida, Inc. (the "Issuer") in a registered direct offering. For each share purchased in the registered direct offering, at a price of $6.00 per share of common stock, the purchaser received one warrant. ( 2 )These securities are held of record by OrbiMed Private Investments V, LP ("OPI V"). OrbiMed Capital GP V LLC ("GP V") is the general partner of OPI V and OrbiMed Advisors LLC ("Advisors"), a registered investment adviser under the Investment Advisors Act of 1940, as amended, is the managing member of GP V. By virtue of such relationships, GP V and Advisors may be deemed to have voting and investment power with respect to the securities held by OPI V noted above and, as a result, may be deemed to beneficially own such securities for purposes of Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Advisors exercises this investment and voting power through a management committee comprised of Carl L. Gordon, Sven H. Borho, and W. Carter Neild, each of whom disclaims beneficial ownership of the shares held by OPI V. The Reporting Person is a member of Advisors. ( 3 )Each of the Reporting Person, GP V and Advisors disclaims beneficial ownership of the securities reported herein for purposes of Rule 16a-1(a) under the Exchange Act, except to the extent of its pecuniary interest therein, if any. This report shall not be deemed an admission that the Reporting Person, GP V or Advisors is a beneficial owner of such securities for the purposes of Section 16 of the Exchange Act, or for any other purposes. ( 4 )Pursuant to an agreement with Advisors and GP V, the Reporting Person is obligated to transfer these securities, or the economic benefit thereof, to Advisors and GP V, which will in turn ensure that such securities or economic benefits are provided to OPI V. ( 5 )The common warrants may be exercised for shares of common stock at any time on or after the date that is six months after the date of their issuance. ( 6 )The expiration date is the earliest of: (a) the third anniversary of the date of their issuance, (b) immediately prior to the closing of a fundamental transaction or (c) the occurrence of certain other events. A "fundamental transaction" includes a consolidation or merger, the sale, transfer or other disposition of all or substantially all of the Issuer's properties or assets, the acquisition of more than 50% of the Issuer's outstanding common stock, any reorganization, recapitalization or reclassification of the Issuer's common stock or any person or group becoming the beneficial owner of 50% of the voting power represented by the Issuer's outstanding common stock.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
