| | 1. | Licensee shall keep reasonable records and books of account with respect to all items for which payments may be due hereunder.
On at least 45 days’ notice, and no more frequently than once per calendar year, Licensor shall be entitled to retain an
independent third party accounting firm reasonably acceptable to audit the records pertaining to payments under this Agreement
for the purpose of confirming the accuracy of payments. Any such audit shall be performed during normal business hours and be subject
to a standard confidentiality agreement. The independent accounting firm shall only be allowed to report the results of the audit.
The audit will be conducted at Licensor’s expense unless the results of such audit establish that inaccuracies in the quarterly
reports have resulted in an underpayment of more than five percent (5%) of the amount due in any quarter, in which case Licensee
will bear the expenses of the audit. In the event of any underpayment, Licensee shall promptly remit to the Licensor all amounts
due together with interest calculated at a daily rate equal to 5%.
