Linked Server

SQL Server 2008 R2

I have a user who is trying to create linked server using one of his programs.  What permissions do I need to give that user to create those linked servers?

He is trying to call the following:

master.dbo.sp_addlinkedserver

master.dbo.sp_addlinkedsrvlogin

master.dbo.sp_serveroption

But gets these errors:

EXEC master.dbo.sp_addlinkedserver @server = N'SQLXYZ\XYZ', @srvproduct=N'SQL Server'

EXEC master.dbo.sp_addlinkedsrvlogin @rmtsrvname=N'SQLXYZ\XYZ',@useself=N'False',@locallogin=NULL,@rmtuser=N'fp',@rmtpassword='xxx'

EXEC master.dbo.sp_serveroption @server=N'SQLXYZ\XYZ', @optname=N'collation compatible', @optvalue=N'false'

.........

Thanks for your help.
