A consortium may be a permanent, legally-established grouping or a grouping which has been  constituted informally for a specific tender procedure. All partners of a consortium (i.e., the  leader and all other partners) are jointly and severally liable to the contracting authority.  The participation of an ineligible natural or legal person will result in the automatic exclusion of  that person. In particular, if that ineligible person belongs to a consortium, the whole consortium  will be excluded. No more than one application or tender can be submitted by a natural or legal person whatever the  form of participation (as an individual legal entity or as leader or partner of a consortium  submitting an application/tender). In the event that a natural or legal person submits more than  one application or tender, all applications or tenders in which that person has participated will be  excluded. In case of lots, the candidates or tenderers may submit only one application or tender per lot.  Contracts will be awarded lot by lot and each lot will form a separate contract.  Tenders for parts of a lot will not be considered. Tenderers may not submit a tender for a variant  solution in addition to their tender for the supplies required in the tender dossier. Any tenderer may state in its tender that it would offer a discount in the event that its tender is  accepted for more than one lot.  when submitting their tender. This guarantee will be released to unsuccessful tenderers once the  tender procedure has been completed and to the successful tenderer[s] upon signature of the  contract by all parties. This guarantee will be called upon if the tenderer does not fulfil all  obligations stated in its tender.  The successful tenderer will be asked to provide a performance guarantee of 10% of the amount  of the contract at the signing of the contract. This guarantee must be provided together with the  return of the countersigned contract no later than 30 days after the tenderer receives the contract  signed by the contracting authority. If the selected tenderer fails to provide such a guarantee  within this period, the contract will be void and a new contract may be drawn up and sent to the  tenderer which has submitted the next cheapest compliant tender.
