If Purchaser shall object to Sellers determination that a Additional Milestone has been achieved as set forth in the Post-Closing Assessment Notice, then Purchaser shall deliver a dispute notice (a Post-Closing Milestone Dispute Notice) to Sellers Representative within fifteen (15) days following Sellers Representatives delivery of the Post-Closing Assessment Notice.
If no Post-Closing Milestone Dispute Notice is delivered within the fifteen (15) day time period, then Sellers determination that the Additional Milestone has been achieved, and that the amount of the Milestone Payment specified in the Post-Closing Milestone Dispute Notice is due hereunder, shall be deemed to be accepted and Purchaser shall pay to Sellers those amounts set forth in the Post-Closing Assessment Notice no later than five (5) days after the expiration of such fifteen (15) day time period.
If Purchaser determines in its sole and reasonable discretion that such Additional Milestone has been achieved during the Post-Closing Milestone Period, then within thirty (30) days of such notice from Sellers Representative or, if earlier, within thirty (30) days of Purchasers determination that such Additional Milestone has been achieved, Purchaser shall notify Sellers Representative of its determination and pay to Sellers the Additional Milestone Payment payable in respect of such Additional Milestone.
If Sellers at any time believe that the Second Put Option Condition has been satisfied and Sellers Representative has not received a Second Put Option Notice, the Sellers Representative shall deliver a notice of such achievement to Purchaser no later than thirty (30) days after the expiration of the Second Put Option Period (the Second Put Option Dispute Notice, and together with any Pre-Closing Milestone Dispute Notice and any Post-Closing Milestone Dispute Notice, a Dispute Notice).
Such Post-Closing Assessment Notice may be delivered before or after the expiration of the Post-Closing Milestone Period without affecting Sellers rights to the applicable Milestone Payment, provided that that applicable Additional Milestone was actually achieved prior to the expiration of such Post-Closing Milestone Period.
