Preamble

Whereas, the Agreement has been concluded between VERSARTIS and BI's Affiliated Company Boehringer Ingelheim RCV GmbH & Co KG ("BI RCV") regarding the manufacture of VRS-317. Originally, the Services anticipated under the Agreement did only cover the manufacture of VRS-317 as bulk drug substance.

Whereas, effective October 1, 2013, VERSARTIS and BI RCV amended the Agreement to change some of the exhibits to the Agreement, and to add certain work packages that included the manufacture of drug product in order for BI RCV to provide additional cGMP fill and finish work and additional bulk drug substance services.

Whereas, BI RCV assigned the Agreement, as amended, with all rights and obligations to BI with effect from January 1st, 2014, with the exception of the Quality Agreement, which remained unaffected and for which BI RCV continued to assume all rights and obligations related to it.

Whereas, Versartis wishes to have BI perform additional Drug Substance Services including but not limited to development and optimization and manufacture of additional Phase III Drug Substance and performance of PPQ Runs for the validation of Drug Substance at the Facility.

Whereas, Versartis wishes to have BI perform additional Services for Drug Product, including but not limited to the establishment of the filling process for pre-filled syringes (PFS) and vials at BI's Affiliated Company Boehringer Ingelheim Pharma GmbH & Co. KG ("BI Pharma").
