(5) Notwithstanding the provisions of sub-regulations (2), (3) and (4), as long as the invitation to tender for the first specific procurement under the dynamic purchasing system has not been sent, the authorities responsible for the tendering process may extend the evaluation period provided that no invitation to tender is issued during the extended evaluation period. The authorities responsible for the tendering process shall indicate in the procurement documents the length of the extended period that they intend to apply.
