complaints associated with product containing API, whether received during or after the term hereof. Helsinn will reasonably assist Indevus in investigating API complaints relating to the manufacture or bulk packaging of the API by analyzing API and
manufacturing processes to determine the nature and cause of an alleged API manufacturing defect or alleged API failure. Helsinn will also reasonably assist Indevus, if so expressly required by Indevus from time to time, in the investigation of any
Adverse Experience (AE) reported to either Party when such AEs are reasonably believed to be attributable to the manufacture or bulk packaging of the API. If Indevus determines that any reasonable physical, chemical, biological or other evaluation
should be conducted in relation to an AE or API complaint relating to the manufacture or bulk packaging of the API, Helsinn will reasonably conduct the evaluation and use its reasonable effort to provide Indevus with a written report of such
evaluation within thirty (30) days from receipt of Indevuss written request for same, together with samples of the API from the relevant lot. The obligations and responsibility in connection with the above AEs and the management of the
same shall pertain exclusively to Indevus.



| | 11.2 | Recall Action. If Indevus should elect or be required to initiate a recall, withdrawal, stock recovery or field correction (each, or collectively, a Recall) of
API or product containing API because of supply by Helsinn of API that does not conform to the Specifications and warranties established by this Agreement, subject in any case to Section 14.1 hereunder, Indevus will notify Helsinn and provide
Helsinn a copy of its recall letter prior to initiation of the recall. Helsinn will assist Indevus (and its designee) in an investigation to determine the cause and extent of the problem. All regulatory authority contacts and coordination of any
recall activities will be initiated by, and will be the sole responsibility of, Indevus.
| | ---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 11.3 | Recall Expenses. If a Recall of any product containing API is necessary, requested by any Regulatory Authority or otherwise advisable for any reason, Helsinn and Indevus
shall each bear the costs of the Recall in proportion to each Partys responsibility for the error necessitating the recall or withdrawal. For purposes of this Agreement, such costs shall include the expenses of notification and destruction or
return of the recalled or withdrawn API or Finished Product and all other documented out-of-pocket costs incurred in connection with such Recall but shall not include lost profits or opportunity costs of either Party.
| | ---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 11.4 | Recall Records. Helsinn will maintain complete and accurate records for such periods as may be required by applicable law or regulation.
| | ---- | ----------------------------------------------------------------------------------------------------------------------------------------



| | 11.5 | Discontinuation of Sales. Indevus, at any time and without liability to Helsinn, shall be entitled to cease, permanently or temporarily, sales of Finished Product in any
country if continued sales of Finished Product in such country would be in violation of any applicable laws or regulations, or if Indevus determines that there is an ethically valid reason to cease such sales based on medical or scientific concerns
relating to such Finished Product.
