of any renewal term upon not less than [***] ([***]) months prior written notice to ViroPharma. This Agreement may be terminated by ViroPharma at the expiration of the Initial Term or at the expiration of any renewal term upon not less than [***]
([***]) months prior written notice to OSG. Any termination of this Agreement pursuant to any provision of this Agreement shall be deemed to be a termination of each Project Agreement. Notwithstanding anything to the contrary in this
Section 16.1, but subject to the right to terminate pursuant to any other provisions of this Agreement (e.g., pursuant to Section 16.2 and 16.3) (in which case this sentence will not apply), the Initial Term or any renewal term will
automatically be extended for any period commensurate with the remaining term of any Project Agreements which are then in effect. In such a case, the effective date of termination pursuant to this Section 16.1 will be the termination date of
the last Project Agreement to terminate.

|16.2 | Termination for Material Breach. In addition to the right to terminate pursuant to Sections 16.1 and 16.3, either Party may terminate this Agreement in the event of a
material breach by the other of this Agreement, or one or more of the Project Agreements, provided that the Party asserting such breach first serves written notice of the alleged breach on the offending Party and such alleged breach is not cured
within [***] ([***]) days of said notice; provided further, however, that this Agreement shall not terminate pursuant to this Section 16.2 unless, at the termination of such [***] ([***]) day period, the Party asserting such breach notifies the
other Party in writing of such termination due to a failure to cure the material breach.

|16.3 | Termination for Insolvency. In addition to the right to terminate pursuant to Sections 16.1 and 16.2, if either Party becomes insolvent or suspends its business, or files a
voluntary petition pursuant to any reorganization or insolvency law of any jurisdiction, or consents to an involuntary petition pursuant to any reorganization or insolvency law of any jurisdiction, or makes an assignment for the benefit of
creditors, or applies for or consents to the appointment of a receiver or trustee of all or a substantial part of its property (such Party, upon the occurrence of any such event, a Bankrupt Party), then the other Party to this Agreement
may thereafter immediately terminate this Agreement by giving notice of termination to the Bankrupt Party.

provision of such Section is expressly limited to the term of this Agreement or the applicable Project Agreement.
|---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|16.5 | OSG Obligations upon Expiration or Termination. Upon the expiration or earlier termination of this Agreement or a Project Agreement, OSG will use its commercially reasonable
efforts to assist ViroPharma in the transfer of relevant manufacturing technology and information to another qualified manufacturing site if necessary. ViroPharma will pay OSG for all such efforts in a commercially reasonable amount mutually agreed
upon by the Parties prior to transfer of information. In addition, OSG shall, at ViroPharmas request, return to ViroPharma any unused Active Pharmaceutical Ingredient and all samples and data held or generated by OSG in performing the Services
under this Agreement, and/or all packaging and other Product-related (other than Active Pharmaceutical Ingredient) materials in the possession of OSG (Non-API Materials); provided that ViroPharma shall reimburse OSG for its actual
out of pocket costs incurred in returning to ViroPharma the Non-API Materials in the possession of OSG that are requested by ViroPharma (the Out-of Pocket-Costs). If ViroPharma requests any of such Non-API Materials, and if this
Agreement or a Project Agreement is terminated by ViroPharma for any reason not due to an event contemplated by Sections 16.2 or 16.3 above, then in addition to reimbursing OSG for its Out-of-Pocket Costs, ViroPharma shall pay OSG an additional
amount equal to [***]% of such Out-of-Pocket Costs.
