Once notified, the remaining Syndicated Shareholders shall have ten (10) running days to notify the other party if they exercise their Tag-Along Right (“Tag-Along Notification”) and the number of Syndicated Shares which they will sell, in which case the Parties shall take all the necessary measures to sell collectively. The operation shall be performed within thirty (30) running days after receiving the Tag-Along Notification (or failure of Notification). Otherwise, the procedure above shall be repeated.

SECTION 3.05.Drag-Along Right.

If Bioceres receives from a third party a Firm Offer to Transfer a number of shares in excess of the Syndicated Shares owned by it and Bioceres wishes to accept said Firm Offer, then Bioceres shall be able to force the other Syndicated Shareholders (“Drag-Along Right”) to sell the number of Syndicated Shares owned by them necessary to cover the Firm Offer, under the same terms and conditions of the Firm Offer.
