(104)Contract performance conditions are for laying down specific requirements relating to the performance of the contract. Unlike contract award criteria which are the basis for a comparative assessment of the quality of tenders, contract performance conditions constitute fixed objective requirements that have no impact on the assessment of tenders. Contract performance conditions should be compatible with this Directive provided that they are not directly or indirectly discriminatory and are linked to the subject-matter of the contract, which comprises all factors involved in the specific process of production, provision or commercialisation. This includes conditions concerning the process of performance of the contract, but excludes requirements referring to a general corporate policy. The contract performance conditions should be indicated in the contract notice, the prior information notice used as a means of calling for competition or the procurement documents.
