Entry into a Material Definitive Agreement.

On August 30, 2019, Synthorx, Inc. (the “Company”) entered into a Sub-Sublease (the “Sublease”) with Avelas Biosciences, Inc.

Under the terms of the Sublease, commencing on or around September 1, 2019 (the “Commencement Date”), the Company will sublease approximately 7,109 square feet in the Premises (the “Rented Area”) at the rate of $24,858.23 per month (the “Base Rate”), with no Base Rate payable for the first six months following the Commencement Date. The Base Rate is scheduled to increase to $25,603.97 per month beginning on March 1, 2021, and the Company is also responsible for certain operating expenses throughout the life of the Sublease.
