(c) After a notice of intent to reject is given, Customer shall cooperate with Manufacturer in determining whether rejection is necessary
or justified. Manufacturer will evaluate process issues and other reasons for such non-compliance and notify Customer in writing. Manufacturer shall notify Customer as promptly as reasonably possible as to whether it accepts Customers basis

percent (100%) of all quantities Customer has ordered pursuant to a written quarterly purchase order (a Firm Purchase Order) pursuant to Section 2.3 of this Agreement, provided, however, that if Manufacturer uses its best
efforts but fails to deliver the quantity of Bulk Drug Substance ordered in a Firm Purchase Order, it shall not constitute a breach of this Agreement if all of (a), (b) and (c) are satisfied.

Substance or such other lower minimum quantity as specified in the Firm Purchase Order; and
