If within the thirty (30) days SERAGEN QA makes a determination that SERAGEN believes the Batch to be nonconforming, *** Portions of this page have been omitted pursuant to a request for Confidential Treatment and filed separately with the Commission. 8 <PAGE> SERAGEN shall have the right to reject the Batch in its entirety and shall notify COPHARMA promptly of this decision. If SERAGEN does not reject the Batch within such thirty (30) day period the Batch will be deemed accepted by SERAGEN. Acceptance of the Batch by SERAGEN triggers payment as described in Article VI. Any dispute between COPHARMA and SERAGEN as to whether or not a Batch that has been rejected by SERAGEN is nonconforming will be resolved in accordance with the procedures set forth in Section 2.15 below. 2.13 REPLACEMENT BATCH. COPHARMA shall notify SERAGEN promptly of a rejection of a Batch by COPHARMA QA, or any delay or irregularity encountered during manufacture which could lead to a rejection. SERAGEN and COPHARMA shall promptly and mutually agree upon new dates for the initiation and completion by COPHARMA of the manufacture of a replacement Batch of PRODUCT if required to meet any outstanding purchase order. In the event that a replacement Batch is commenced prior to a rejection and the Parties subsequently determine that the replacement Batch is not required, SERAGEN will bear the costs associated with the manufacture of the replacement Batch, up to the time of such determination. SERAGEN and COPHARMA will negotiate in good faith terms for the continuance or discontinuation of the manufacture of any such replacement Batch. Subject to prior resolution of the dispute in accordance with the procedures set forth in Section 2.15, below in the event there is a dispute between COPHARMA and SERAGEN over whether a Batch is nonconforming, COPHARMA shall replace all non-conforming shipments at its expense, refund any payments made for the nonconforming shipment, and shall reimburse SERAGEN for any reasonable charges incurred by SERAGEN for shipping or storage, if applicable, of the non-conforming shipment. Any replacement Batch of PRODUCT to be manufactured by COPHARMA shall be invoiced by COPHARMA in accordance with the purchase order placed by SERAGEN for the nonconforming shipment of PRODUCT. 2.14 DESTRUCTION OF NONCONFORMING PRODUCT.

SERAGEN, or its designees, shall return all rejected Batches to COPHARMA, at COPHARMA's expense, for destruction. Representatives of SERAGEN shall be permitted to witness the destruction of nonconforming PRODUCT under this section, and shall receive from COPHARMA proof of such destruction, upon written request. 2.15 RESOLUTION OF DISPUTES. In the event of dispute between the Parties over the validity of a Batch rejection for failure to meet PRODUCT Specifications, the Parties agree to submit a representative sample of the rejected Batch to a qualified independent cGMP test facility to be agreed upon by the Parties, and to accept the results of the testing performed by that facility as binding with regard to that Batch. The testing procedures utilized must be formerly transferred 9 <PAGE> and qualified at the independent test facility prior to performing the testing. The expense of such testing shall be borne by the losing Party. In the event that the Parties cannot resolve a dispute regarding conformance with cGMPs and/or required MRR Documentation, the Parties shall submit the issue to a mutually agreed upon expert cGMP organization. The findings of the expert cGMP organization shall be binding on the Parties, absent manifest error. COPHARMA shall bear such expenses of the cGMP organization if the findings confirm the non-conformity, and SERAGEN shall bear such expenses if the findings confirm that the PRODUCT was manufactured in accordance with cGMPs and/or required MRR Documentation. The Parties agree to make all efforts in good faith to resolve disputes within 60 days. 2.16 ADDITIONAL SERVICES. Clinical product storage, cell line stock, storage, and reference standard storage and regulatory/CMC consulting requested by SERAGEN will be provided by COPHARMA all in accordance with cGMPs; and all other regulatory requirements and filings as applicable.

The pricing of PRODUCT and FDP release and stability testing set forth on Exhibit B is based upon the current Manufacturing and Release Requirements for first generation PRODUCT, the anticipated Manufacturing and Release Requirements for second generation PRODUCT, and the current release and stability testing procedures for FDP, as well as current regulatory requirements. In the event that any regulatory requirements change or the manner of producing the PRODUCT or performing release and stability testing for FDP, as set forth on Exhibit A or as anticipated for second generation PRODUCT, changes, in such a way to increase or decrease the cost or burden on COPHARMA to manufacture the PRODUCT or perform such release and stability testing, the parties agree to negotiate an appropriate price adjustment. Similarly, the pricing of PRODUCT and FDP release and stability testing set forth on Exhibit B is based upon the number of inquiries, requests for information and explanation, and similar forms of correspondence which COPHARMA would expect to have from a customer of its contract manufacturing services. In the event that the burden of answering and dealing with such inquiries, requests for information and explanation, and other similar forms of correspondence from SERAGEN is greater than the burden associated with the provision of similar services to other customers the parties agree to negotiate appropriate pricing increases. 6.05 DELIVERY OF PRODUCT. Delivery shall be FOB the COPHARMA Plant located at 97 South Street, Hopkinton, Massachusetts or such other location as agreed to by the parties. SERAGEN shall, at its cost, ensure that adequate insurance coverage, for full replacement cost, exists on PRODUCT in transit to SERAGEN or its designee in the event that such PRODUCT is damaged, destroyed or lost, and shall bear all costs of such insurance.
