The tenders must include the following: All tenders must contain a financial tender to be submitted  according to the form in  section 4. Annexes . The tenderer's attention is drawn to the following points:  The price for the tender must be quoted in euro. Tenderers from countries outside the euro zone  have to quote their prices in euro. The price quoted may not be revised in line with exchange  rate movements. It is for the tenderer to bear the risks or the benefits deriving from any  variation.
