Explanation of Responses:
1. This transaction was previously reported in the reporting person's original Form 3 filed with the Securities and Exchange Commission (the "SEC") on March 22, 2017, as amended by the reporting person's Form 3/A filed with the SEC on February 28, 2018 (the "Original Form 3"). This transaction is not new or revised, but is being reported again such that the system does not, by default, indicate that "no securities are beneficially owned" by the reporting person.
2. One fourth (1/4) of the shares underlying this option vested on June 20, 2017, and the remainder of the shares underlying this option vest at a rate of one forth-eighth (1/48) per month thereafter, provided the reporting person provides services to Five Prime Therapeutics, Inc. through each such date.
This amendment is being filed to attach the reporting person's Power of Attorney, which was inadvertently omitted from the Original Form 3. No other changes are being made to the Original Form 3. Exhibit List: Exhibit 24 - Power of Attorney

      The undersigned, hereby constitutes and appoints Marc Belsky and Francis

the undersigned's name, place and stead, to:

      1. Complete and execute Forms 3, 4 and 5 under the Securities Exchange Act

thereto on the undersigned's behalf as such attorney-in-fact shall in his
discretion determine to be required or advisable pursuant to Section 16 of the
Exchange Act and the rules and regulations promulgated thereunder, or any
successor laws and regulations, as a consequence of the undersigned's beneficial
ownership of securities of FivePrime or changes in such beneficial ownership;

      2. Do all acts necessary in order to file such forms and amendments with
the Securities and Exchange Commission, any securities exchange or national
