Following conversion of such licence to an exclusive licence in respect of such Non-Proprietary Peptide, if Sanofi abandons the development of such Non-Proprietary Peptide, such licence shall become non-exclusive. In the event that Ascendis has declined Sanofi’s request for an exclusive licence for a Non-Proprietary Peptide and Ascendis subsequently abandons the development of such Non-Proprietary Peptide, Sanofi shall then be entitled to an exclusive licence to such Non-Proprietary Peptide.

2.5 | Each Party agrees that:

Ascendis shall promptly inform Sanofi in writing after completion of any such transaction with such licensees and/or Sub-Licensees involving a transfer or extension by Ascendis of the Immunity hereby granted, and such notice shall include the identity of such licensees and/or Sub-Licensees and a description of the therapeutic field (but not the financial terms) of the licences granted. For clarity, the Immunity hereby granted to Ascendis does not create any obligation on Sanofi to disclose to Ascendis any Technical Information relating to a Manufacturing Improvement or to a Sanofi Medical Device.

2.9 | Non-compete: During the term of this Agreement, and subject to expiry or termination of this Agreement, Ascendis shall not directly or indirectly engage, either by itself or on behalf of any Independent Third Party, in any research, development or commercialization activities in connection with [***].

In the event that the development of a First Product or a Second Product is suspended or discontinued (each a “Suspended Product”), and another Product is developed instead of the Suspended Product (each a “Replacement Product”), any payments actually paid under Clause 7.1(C)(1) to Clause 7.1(C)(8), inclusive, in respect of the Suspended Product shall not be due in respect of the Replacement Product but any payments not paid in respect of the Suspended Product shall be payable on the Replacement Product achieving the relevant milestone described in Clause 7.1(C)(1) to Clause 7.1(C)(8), inclusive. For clarity, Sanofi may not be obliged to pay to Ascendis more than [***] under this Clause 7.1(C).

For the avoidance of doubt, in the event that the milestones described in Clause 7.1(C)(9) and Clause 7.1(C)(10) are achieved in the same calendar year, both payments shall be paid by Sanofi to Ascendis.

Sanofi shall provide Ascendis with written notice of the achievement of any of the foregoing events within [***] thereafter. Upon receipt of such notice, Ascendis shall submit an invoice to Sanofi for the amount of such milestone payment, and Sanofi shall pay the respective payment for such event within [***] after receipt of such invoice from Ascendis.

7.3 | Subject to Clause 7.4, Ascendis shall bear any and all taxes levied on account of any payment received under this Agreement. In the event that Sanofi is required, under applicable laws, to withhold any deduction or tax from any payment due to Ascendis under this Agreement, such amount shall be deducted from the payment to be made by Sanofi, paid to the proper taxing authority, provided that Sanofi shall take reasonable and lawful actions to avoid and minimize such withholding and promptly notify Ascendis so that Ascendis may take lawful actions to avoid and minimize such withholding.

8.2 | Each Party will have the right to have an independent certified public accounting firm of internationally recognized standing, reasonably acceptable to the other Party, have access during normal business hours, and upon [***] prior written notice, to such of the records of the other Party and its Affiliates as may be reasonably necessary to verify the accuracy of any payment made or received during the [***] prior to the date of such request; provided, however, that no Party will have the right to conduct more than one such audit in any [***] period. The accounting firm will disclose to the Parties only whether the data reported by the audited Party are correct or incorrect and the specific details concerning any discrepancies. The auditing Party will bear all costs of such audit, unless the audit reveals a discrepancy in the auditing Party’s favour of more than [***], in which case the audited Party will bear the cost of the audit. The results of such accounting firm will be final, absent manifest error.

8.3 | If, based on the results of any audit, additional payments are owed Ascendis under this Agreement, then Sanofi will make such additional payments promptly after the accounting firm’s written report is delivered to both Parties.

10.6 | Promptly upon execution of this Agreement, each Party may issue an initial press release disclosing the execution of this Agreement and its contents, subject to the prior written consent of the other Party (which consent shall not be unreasonably withheld or delayed) to the contents of such press release.

11. | Prosecution, Maintenance and Defence

11.1 | Sanofi shall be responsible for filing, prosecuting and defending the Product Patents and any new patent Covering a Product, a Sanofi Improvement or a Joint Improvement.
