(1) The Minister may use direct public procurement —
(a) where only one supplier has the exclusive right to manufacture the goods, carry out the works, or perform the services to be procured, and no suitable alternative is available;
(b) where additional deliveries of goods by the original supplier which are intended either as partial replacement or extension for existing goods, services, or installations and where a change of supplier would compel the procuring entity to procure equipment or services not meeting requirements of inter-changeability with already existing equipment or service;
(c) where additional works, which were not included in the initial public procurement contract have, through unforeseeable circumstances, become necessary and the separation of the additional works from the initial public procurement contract would be difficult for technical or economic reasons;
(d) where goods or services are supplied for the Constituency Development Programme or any other programme designated by Cabinet, by order published in the Gazette;
(e) where the nature of the procurement requirement necessitates that a particular person be selected due to unique qualifications;
(f) where the procurement requirement is for a professional service and time constraints make the use of any other procurement procedure impractical;
(g) where continuity of the procurement requirement is essential to meet the objectives of the public procurement; or
(h) where infrastructure is in urgent need of repair.
(2) Where direct public procurement under subsection (1) is used, the procuring entity may request a proposal or request a sealed quotation from one supplier.
