1. We do not opine on the validity, binding effects, enforceability and effectiveness of the Opinion Documents.

Guarantee obligations and security interests arising from, or created under, the Opinion Documents will be null and void if these prohibitions are infringed.

Please note that, as per Organic Law 5/1995, of May 22, on Jury Trial, jury trial is not waivable under Spanish law.
