6

| UNIVERSITY to terminate this Agreement pursuant to Section 10.2(a); except that for a single time, if a milestone in Section 3.2 has not been completed within the time frame allotted through no fault of LICENSEE and following the best efforts of LICENSEE to meet such milestone, LICENSEE may, on a one-time basis, notify the UNIVERSITY in writing that it desires a single six (6) month extension to meet such milestone and LICENSEE shall be deemed to have fulfilled the milestone requirement if LICENSEE makes a penalty payment of [***] dollars ($[***]) with both notice and penalty payment to be received by the UNIVERSITY within ten days of the applicable milestone achievement date.

Payment of such interest by LICENSEE shall not negate or waive the right of UNIVERSITY to seek any other remedy, legal or equitable, to which it may be entitled because of the delinquency of any payment, including, but not limited to, termination of this Agreement as set forth in Article 10. Licensee shall reimburse University for any costs and expenses incurred in connection with collecting any overdue balance of payments with respect to Licensee’s payment and reimbursement obligations under this Agreement, including the costs of engaging counsel or a collection agency for such purpose.

7.5 | In any infringement suit either party may institute to enforce PATENT RIGHTS pursuant to this Agreement, the other party shall, at the request and expense of the party initiating such suit, cooperate in all respects and, to the extent possible, have its employees testify when requested and make available relevant records, information, samples, specimens, and other evidence upon request.
