If, at any time during the Term, ZAI develops and intends to advance any such Immuno-Oncology Asset into human clinical trials in the ZAI Territory, then at least six months prior to the initiation of any human clinical trial of such Immuno-Oncology Asset in the ZAI Territory, ZAI will notify TESARO in writing of such intent and provide TESARO with a confidential written summary of the Immuno-Oncology Asset, including all material clinical, pre-clinical and other relevant data that TESARO may reasonably request which would be necessary for TESARO to determine whether to exercise its right to license such Immuno-Oncology Asset under this Section 8.1(b) (a “Transaction Notice”), which Transaction Notice shall be deemed to be Confidential Information of ZAI under this Agreement. TESARO will notify ZAI within [***] of its receipt of the Transaction Notice whether TESARO would like to exercise its right under this Section 8.1(b) to obtain an exclusive, worldwide (excluding China), sub-licensable, royalty-bearing license to research, develop, manufacture and commercialize the applicable Immuno-Oncology Asset for all uses (an “Option Notice”). For a period of [***] following ZAI’s receipt of an Option Notice, TESARO and ZAI will negotiate in good faith commercially reasonable terms for the foregoing license of the applicable Immuno-Oncology Asset to TESARO. If TESARO does not deliver an Option Notice to ZAI within the applicable [***] period, or declines in writing its option to take a license to the applicable Immuno-Oncology Asset after review of the Transaction Notice, then TESARO shall be deemed to have waived its rights under this Section 8.1(b) solely with respect to the applicable Immuno-Oncology Asset, and ZAI will be free to enter into a license for such Immuno-Oncology Asset with any Third Party thereafter. If TESARO exercises its option by providing the Option Notice with respect to the applicable Immuno-Oncology Asset, but TESARO and ZAI do not mutually agree on the terms of a license to TESARO within the [***] negotiation period described above, ZAI may not enter into any license transaction for such Immuno-Oncology Asset outside of the ZAI Territory with any Third Party for a period of [***] following the end of such [***] negotiation period (the “Restricted Period”). After the end of the Restricted Period, ZAI is permitted to negotiate a license for the applicable Immuno-Oncology Asset with a Third Party; provided, however, that ZAI may not enter into a license for the applicable Immuno-Oncology Asset with a Third Party on financial terms that are materially less favorable, in the aggregate, to ZAI than those offered by TESARO (collectively, the “Third Party Terms”). [***] For the sake of clarity, nothing in this Section 8.1(b) shall be deemed to restrict ZAI’s ability to grant of a license to a service provider or to a Third Party distributor selling finished Immuno-Oncology Product purchased from ZAI.
