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.

San Diego and Shanghai, June 14, 2013 — Ambrx and Zhejiang Medicine Co. Ltd.

Under the agreement, Ambrx and ZMC will continue the development of ARX788, with ZMC bearing the ongoing development cost. ZMC will receive commercial rights in China while Ambrx retains commercial rights outside of China and receives royalties on sales of the product in China.

WuXi PharmaTech will provide integrated services for ARX788, including the development and manufacturing of the toxin, antibody and ADC, pre-clinical development and clinical trials.

“We are excited to initiate this unique collaboration with ZMC and WuXi, which allows us to team up with China’s leading pharmaceutical and CRO companies to efficiently develop ARX788, our most advanced ADC therapeutic candidate for both breast cancer and gastric cancer indications,” said Lawson Macartney, Ph.D., Chief Executive Officer of Ambrx. This collaboration allows Ambrx to further extend our pipeline of ADCs and gain access to the China market through our partnership with ZMC. Our experience with site-specific ADC technology has shown that we have the potential to create best-in-class therapeutic candidates, and we look forward to advancing ARX788 into the clinic to understand its full potential.”

We will work with WuXi PharmaTech to accelerate the development and commercialization of ARX788 in China to bring benefits to Her2-positive cancer patients. The partnership will help ZMC undertake pioneering work in the development of monoclonal antibodies and ADCs. The partnership will also help ZMC establish long-term and mutually beneficial relationships with leading global companies and advance our position in the biopharmaceutical industry. “
