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 Purchaser’s 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’ Representative delivers such a notice and Purchaser determines, in its sole and reasonable discretion, that the applicable Additional Milestone has not been achieved, then, within thirty (30) days of Sellers’ Representative’s notice Purchaser shall notify Sellers’ Representative of such determination. If Sellers’ Representative believes that Sellers are entitled to payment of all or any portion of an Additional Milestone Payment hereunder which they have not received within thirty (30) days following the achievement of the Additional Milestone for which payment is due, Sellers’ Representative may, not later than twelve (12) months following the achievement of such Additional Milestone, deliver to Purchaser a notice setting forth Sellers’ Representative’s determination that all or a portion of such Additional Milestone Payment is due under this Agreement (the “Post-Closing Assessment 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. 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’ Representative’s delivery of the Post-Closing Assessment Notice. A representative of Purchaser, on the one hand, and the Sellers’ Representative, on the other, shall attempt in good faith to resolve any such objections within fifteen (15) days of the receipt by Sellers of the Post-Closing Milestone Dispute 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.
