Audit select , but not audit the queries launched by a certain user

Hello,

On Oracle 11.2.0.3

I need to audit all select operations on some tables in one schema.

But i should not audit the queries launched by a certain user,

(exclude from the audit the queries started by application to limit the size of the audit)

Is there any idea how can i achieve this ?

example  :

AUDIT SELECT ON IBPFA.ABGRE240 BY ACCESS WHENEVER SUCCESSFUL;

But I dont want to have audit entries for the selects run on IBPFA.ABGRE240 launched by IBPFA user.

Thanks
