SBIR Phase 3 contracts follow the UCF like any other federal contract and enjoy few special FAR provisions such as limited competition for Phase 2 and 3 direct awards and SBIR unique DFARs data rights provisions.

Use of FAR 52-244-2 is prescribed at FAR 44.204(a) Contract Clauses.  There is no specific exclusion for the clause, but I enourage you to speak to your contracting officer if you have a paricular concern.
