(1) Contract awards exceeding $25,000 that are—
(i) Covered by the World Trade Organization Government Procurement Agreement or a Free Trade Agreement (see subpart 25.4); or

(3) A notice is not required under this section if the notice would disclose the executive agency's needs and the disclosure of such needs would compromise the national security.
(b) A notice is not required under paragraph (a)(1) of this section if—
(1) The award results from acceptance of an unsolicited research proposal that demonstrates a unique and innovative research concept and publication of any notice would disclose the originality of thought or innovativeness of the proposed research or would disclose proprietary information associated with the proposal;
(4) The award is made for perishable subsistence supplies;
