The circumstances invoked to justify extreme urgency shall in no way be attributable to the any department or staff of The Procuring Entity. For purposes of this clause, exceptional circumstances situations shall be one of the following situations:i) Where there is likely to be injury or loss of life; ii) Where there is likely to be damage to property; or iii) Where there is a situation arising from “Force Majeure”. b) where, for technical reasons, or reasons involving the protection of exclusive rights/proprietary goods, services, the contract can be awarded only to a particular economic operator; c) where, pursuant to Article 46, existing contracts are amended for: (i) complementary services not included in the main contract but which, due to unforeseen circumstances, have become necessary to perform the contract, provided that the complementary services are technically and economically inseparable from the main contract, without bringing serious inconveniences for the Procuring Entity additional services consisting of the repetition of similar services entrusted to the contractor furnishing the services under the initial contract, provided that a procurement notice has been published for the initial contract and that the possibility of using the negotiated procedure for further services for the project as well as the estimated cost, were clearly indicated in the Bidding Documents or the Terms of Reference for the initial contract. (ii) additional deliveries by the original contractor intended either as a partial replacement of normal goods or installations or as the extension of existing contracts for goods or works, where a change of contractor would oblige the Procuring Entity to acquire equipment having different technical characteristics which would result in either incompatibility or disproportionate technical difficulties in operation and maintenance. (iii) additional works not included in the initial contract which due to unforeseen circumstances, became necessary for carrying out the works described therein and have been awarded to the contractor already carrying out the work: a) where such works cannot be technically or economically separated from the main contract without serious inconvenience to the beneficiary; and b) where such works, although separable from the performance of the original contract, are strictly necessary to its completion. 22
