These license grants apply to Your Content. You understand that you will not receive any payment for any of the rights granted in Sections 4.4 to 4.6. The licenses you grant hereunder are perpetual.

However, you waive these rights and agree not to assert them against PSI, to enable PSI to reasonably exercise the rights granted in Section 4, but not otherwise.

To the extent this Section is not enforceable by applicable local law, you grant PSI the rights PSI needs to use Your Content without attribution and to make reasonable adaptations of Your Content as necessary to render the Website and provide the Services.
