6 million + records, query takes more than 50 min to execute.

I am trying to get records from a table which has more than 6 million of records.
The value set of the particular col IND can be
NULL
'0'
'1'
and other value like A B '6'
The data type of IND is varchar.
I want all the records where the value is other than NULL, 0 and 1
I tried this simple query
SELECT ID, IND
FROM tablename
WHERE
IND IS NOT NULL
AND IND <> '0'
AND IND <> '1'
Now this query is taking more than 30-40 min. Is this a way I can speed up this query. Also I can't index on the column.
any suggestions ?
