5.2 Delivery Without Certificate of Analysis. At Customer’s request, WuXi will Deliver Product in quarantine prior to delivery of the Certificate of Analysis. Such request shall be accompanied by Customer’s written acknowledgement that the Product has been Delivered without the transmittal to Customer of a Certificate of Analysis, that accordingly the Product cannot be administered to humans until transmittal of the Certificate of Analysis, and that Customer nevertheless accepts full risk of loss, title and ownership of the Product. The Delivery of Product in quarantine will be subject to such testing requirements as WuXi may reasonably require, and the forty-five (45) day period referred to in Section 5.8 will run from Delivery in quarantine by Customer of the Product.

5.3 Packaging and Labeling. Unless otherwise agreed, WuXi shall package and label Product for Delivery in accordance with its standard operating procedures and in accordance with required shipping conditions.

5.4 Insurance. If requested in writing by Customer, WuXi will (acting as agent for Customer) arrange for insurance of Product while held by WuXi after Delivery (awaiting transportation) for a maximum of fourteen (14) days on terms equivalent to those under which WuXi insures product prior to Delivery. Third party expenses incurred by WuXi in arranging such insurance must be agreed to in advance in writing and will be charged to Customer in addition to the Price.

6.1 Non-Conforming Product. Within thirty (30) days following Delivery of Product and copies of the relevant production batch records in English, including copies of the CoA, CoC, and BSE/TSE certification provided at Delivery, Customer shall determine whether the Product conforms to the Specifications and has been manufactured in material accordance with such batch records. If Customer determines that the Product fails to meet Specification, or was not produced in material accordance with the batch records Customer shall give WuXi written notice within such 30 day period and shall return such Product to WuXi’s premises, at WuXi’s expense, for further analysis. In the absence of such written notice, Product shall be deemed to have been accepted by Customer as meeting Specification and Customer has waived its right to revoke acceptance. If Customer reasonably demonstrates to WuXi that Product returned to WuXi fails to meet Specification or was not manufactured in material accordance with the batch records and that such failure is due to the negligence of WuXi and not due in whole or in part to the inherent property of the Product or Process, or acts or omissions of Customer or any third party after Delivery, WuXi shall at its option either refund that part of the Price that relates to the production of such non-conforming Product, or initiate a manufacturing run within sixty (60) calendar days from the date it was determined that the Product was non-conforming to replace such Product at its own cost and expense.

6.2 Non-Conforming Test. If, within fourteen (14) calendar days of receiving a result from a test conducted by WuXi, Customer notifies WuXi in writing that the result is unexpected, WuXi will initiate a laboratory investigation of the result. The Customer and WuXi will agree on an appropriate course of action pending the results of the laboratory investigation. If WuXi observes an Out Of Specification (OOS) result it will notify Customer as soon as reasonable but in any case within two (2) working days of learning of such result. Customer and WuXi will agree on the appropriate course of action to investigate the OOS result. If WuXi determines that an unexpected, or OOS result is due to the inherent condition of the sample matrix, or to the act, omission, direction, or negligence of Customer or any third party outside of WuXi’s control, Customer shall be liable to WuXi for the Price of the Services performed, including any additional testing or retests, and materials, reagents, expenses consumed, employed, or specially obtained during the course of the laboratory investigation. If the unexpected or OOS result was caused by a combination of the inherent property of the sample matrix or the act, omission, direction, or negligence of Customer or any third party outside of WuXi’s control and WuXi error, or a reasonable determination of cause cannot be ascertained, Customer shall be liable for 50% of the Price of the Services performed, including any additional testing or retests, and 50% of the cost of any materials or reagents specially obtained by WuXi during the course of the laboratory investigation. Customer is not liable to WuXi for unexpected, or OOS results due to WuXi error and WuXi shall provide a refund of any payments made by Customer for the Services giving rise to the unexpected or OOS results. Should Customer request a repeat or retest of such non-conforming Services Customer shall be liable for the Price of a successful repeat or retest of such non-conforming Services.

7

7. Records

Records of Services are available for Customer review at the WuXi facility where the Services were performed. WuXi will retain Batch, laboratory and other technical records (“Records”) of Services for the longer of ten (10) years or for the minimum period required by applicable law and consistent with FDA, EMA, or other relevant Competent Authority regulations and guidance relating to the manufacture or testing of products intended to support an application for regulatory approval. Technology Development Contracts shall include copies of protocols, test methods, method qualification/validation reports. To the extent that raw data from Services or descriptions of any of WuXi’s protocols, test methods, or SOPs are not included in the Customer-approved protocol Technology Development Contract, or Report pertaining to any particular Service and are required by a competent regulatory authority, WuXi will upon written request by Customer provide a copy of such raw data or relevant portions of such protocols, test methods, or SOPs to be used solely for purposes of such regulatory submission under the provisions of Confidentiality in accordance with Section 10. In the event WuXi proposes to dispose of Records WuXi shall provide Customer written notice thereof. If within thirty (30) days after such notice Customer requests any Records, WuXi shall provide to Customer at Customer’s expense such Records rather than disposing thereof. WuXi may, however, retain copies of any Records as are reasonably necessary for regulatory or insurance purposes, subject to WuXi’s obligation of confidentiality.

All the original lab notes will be in Chinese to meet Chinese regulatory requirements. All technical reports and regulatory dossiers will be in both Chinese and English.
