how did you know 'jane doe' was the primary vs joe klein the secondary? If you had a column "Contact Type", the query:

select name, age, amount,

     max( decode( contact_type, 'PRIMARY', contact, null ) ) primary_contact,
     max( decode( contact_type, 'SECONDARY', contact, null ) ) secondary_contact

  from T
 group by name, age, amount
/

would work....
