4. (4) Does not demonstrate an innovative and unique method, approach, or concept, or is otherwise not deemed a meritorious proposal.

1. (1) An unsolicited proposal has received a favorable comprehensive evaluation;

2. (2) A justification and approval has been obtained (see 6.302-1(a)(2)(i) for research proposals or other appropriate provisions of subpart  6.3, and 6.303-2(c));

3. (3) The agency technical office sponsoring the contract furnishes the necessary funds; and
