spoon licence (apache licence) shoule we as company pay?

Hi All!


I would like to ask you,

should we as a company be paying any money according to the license under the link below?

http://community.pentaho.com/projects/data-integration/

if you scroll a bit down, on the right side there is a 'License' section,

when you click in, you are redirected to Apache License


So according to this license, should we be obliged to pay any money?

Only contributions (e.g. money) can be sent?


Would be very glad if you could share some thoughts.


Regards,
bob.
