Can you change it to this query:

 SELECT count(1) FROM RF_BALANCE_T b, rf_security_by_dceid s  WHERE
 (s.award_number = 'ALL')

 OR (b.award_number = s.award_number AND s.project_number = 'ALL')
 OR (b.award_number = s.award_number AND b.project_number=
 s.project_number AND s.task_number = 'ALL')
 OR (b.award_number = s.award_number AND b.project_number=
 s.project_number AND b.task_number = s.task_number)
