2. Legal effects of the invitation to tender and submission of a tender.  The time-limit for receipt of tenders is indicated under Heading IV.2.2 of the contract notice  where local time shall be understood as local time at the contracting authority's location  (the location indicated under Heading I.1 of the contract notice). A tender received after the time-limit for receipt of tenders will be rejected. The submission  receipt provided by e-Submission with the official date and time of receipt of the submission  (timestamp) constitutes proof of compliance with the time-limit for receipt of tenders 4 . Tenderers must ensure that their submitted tenders contain all the information and  documents required by the contracting authority at the time of submission as set out in  the procurement documents.  The Declaration(s) on honour on exclusion and selection criteria shall be dated and signed,  either by hand or by applying a qualified or an advanced electronic signature based on a  qualified certificate, by an authorised representative of the signatory. When the  declaration(s) on honour are signed by hand, a scanned copy must be attached to the  tender in e-Submission. After submitting a tender, but before the deadline for receipt of tenders, a tenderer may  definitively withdraw its tender 5 , or withdraw it and replace it with a new one 6 . A withdrawal receipt will be provided by e-Submission as proof of withdrawal.  All costs incurred for the preparation and submission of tenders are to be borne by the  tenderers and will not be reimbursed. This invitation to tender is in no way binding on the contracting authority. The contracting  authority's contractual obligation commences only when the contract with the successful  tenderer is signed by both parties.  Up to the signature of the contract the contracting authority may cancel the procurement  procedure without tenderers being entitled to claim any compensation. Any such decision  must be substantiated and tenderers notified.  The validity period of the tender, during which tenderers may not modify the terms of their  tenders in any respect, is indicated under Heading IV.2.6 of the contract notice. Submission of a tender implies acceptance of all the terms and conditions set out in the  procurement documents and, where appropriate, waiver of the tenderer's own general or  specific terms and conditions. The submitted tender is binding on the tenderer to whom  the contract is awarded for the duration of the contract.  4 If no submission receipt is received in reasonable time after submission, please contact the e-Submission  Helpdesk (see contact details in the above referred e-Submission Quick Guide) as soon as possible.  5  A submitted tender can be withdrawn directly in the "Procurement/My Submission(s)" area in the F&T Portal.  For detailed instructions on how to withdraw a tender please consult the above referred e-Submission Quick  Guide.  6  To submit a new version, the tenderer must create a new tender in e-Submission and include all the information  and documents required in the procurement documents with the submission of a tender, even if some of them  have already been included in the replaced tender. 2
