Product Specifications, NANOGEN may reject such Development Product by giving written notice to PBM within 30 days after NANOGENs receipt of such Development Product from PBM or within 30 days of any return from a customer of a Development
Product that does not conform to the Development Product Specifications. Any notice given under this provision must specify the manner in which the Development Product fails to conform to the Development Product Specifications. If there is a
disagreement between the Parties as to whether any Development Product meets the Development Product Specifications, then samples and/or batch records, as appropriate, from the batch that is in dispute will be submitted promptly for testing and
evaluation to an independent third party (including a third party testing laboratory) as shall be agreed to in writing by both Parties. Should the Parties be unable to agree on an independent third party testing laboratory, an arbitrator shall be
appointed under the arbitration provisions of this Agreement for the sole purpose of choosing such an independent third party testing laboratory. The determination of such third party as to whether such Development Product meets the Development
Product Specifications will be final and binding. If it is determined that the nonconformity to the Development Product is caused by a NANOGEN Reagent, or by negligent or deliberate acts ofNANOGEN or its agents, or which occurs subsequent to the
proper delivery of such Development Product to NANOGENs carrier for shipment, PBM shall have no liability to NANOGEN with respect to such nonconformity and the cost of any testing and evaluation by a third party shall be borne by NANOGEN and
NANOGEN shall bear all costs of manufacturing and destruction of Development Products that are or become nonconforming without fault on the part of PBM. If the nonconformity is caused by a defect in manufacturing by PBM, the cost of any testing or
evaluation by a third party shall be borne by PBM and, PBM shall at its option replace or repair such nonconforming Development Product within 60 days of such determination at no additional cost to NANOGEN and shall reimburse NANOGEN for the cost of
Nanogen Reagents included in the nonconforming products arising from such defect in manufacturing by PBM.

being considered, and B is the list selling price of the other products sold separately during the royalty period being considered.

(ii)
If the Combination Product contains other products which are not sold or offered for sale separately in a particular market or during the royalty period being considered, the Net Sales of that Combination Product shall be determined as sales of a
Licensed Product alone.

|-- | --------------------------------------------------------------------

Combination Product shall mean a SYN-X Licensed Product sold in combination with any other products and/or services, whether packaged together or separately, in particular a SYN-X Licensed Product designed to also measure
