If the WFOE’s board of directors decides that Corvus Cayman will be the listing vehicle of the Group Members (the “Board Decision on Corvus Cayman’s Listing”), the Parties agree to negotiate in good faith for a solution that enables the equity interest of WFOE held by the Warrant Holders to be exchanged into the shares of Corvus Cayman.
