The following is a description of the compensation arrangement for Randal J. Kirk, Precigen, Inc.’s (“Precigen”) Executive Chairman (the “Compensation Arrangement”). The Compensation Arrangement is not set forth in a formal written document, and therefore Precigen is providing this description pursuant to Item 601(b)(10)(iii) of Regulation S-K:

Mr. Kirk received prorated compensation consistent with the foregoing elements for the nine months of 2020 not covered by Mr. Kirk’s previous compensation arrangement with Precigen, which expired on March 31, 2020. Equity awards granted to Mr. Kirk pursuant to the terms of the Compensation Arrangement are granted under Precigen’s 2019 Incentive Plan for Non-Employee Service Providers and the forms of award agreements used for Precigen’s other director awards.
