I got this "single-row subquery returns more than one row"

and my Query is 

Select contact_ID from contact where (

Select b.Contact_ID from company a, contact b where a.Company_ID =  b.Company_ID 
and a.IS_ACTIVE <> 'N' and b.IS_ACTIVE <> 'N'
and a.CREATED_DATE >= '01-Jun-2013') =
(
Select b.Contact_ID from company a, contact b where a.Company_ID =  b.Company_ID 
and a.IS_ACTIVE <> 'N' and b.IS_ACTIVE <> 'N'
and a.CREATED_DATE < '01-Jun-2013');
