You just want rows where ActivityID = 0 and PeriodStart < _PeriodEnd and PeriodEnd > _PeriodStart? Why not just ...

SELECT * FROM BudgetActivities
WHERE WHERE ActivityID = 0
AND PeriodStart < _PeriodEnd
AND PeriodEnd > _PeriodStart
ORDER BY ActivityGroupID,ActivityID;

If that's still slow, try adding indexes on activitygroupid and on periodstart, periodend.
