In addition, Client shall deliver to Catalent within [***] following the end of each calendar quarter following Launch (i) a written statement setting forth in reasonable detail its calculation of the contingent sale fee set forth in Section 3.1(B) or 3.2(B), if any, due for such most recently completed calendar quarter, including its calculation of Net Sales and all appropriate backup information, and (ii) payment of the contingent sale fee due on such Net Sales.

Client shall provide the auditors with access during normal business hours to appropriate space at Client’s relevant location and to such of the pertinent books and records of Client as may be reasonably necessary to verify the matters in question; provided, that such

auditors shall be subject to the obligations of confidentiality at least as strict as those set forth in this Agreement. Prior to disclosing the results of any such audit to Catalent, the auditors shall present Client with a preliminary report of findings and provide Client with an opportunity to respond to any questions raised or issues identified. If an audit discloses an underpayment by Client of any amounts paid pursuant to any provision of this Agreement, such amounts shall be paid to Catalent within [***] after the date Client receives the auditors’ final written report.
