Amy, the context is as follows:
In one of the former Soviet Union republics there is a gas field. And an alliance of 3 Companies has the right for this field. The text itself is not a legal document, it’s a thesis written by a student.
I guess I’d prefer sentence 2. However, I’d probably choose to say either ‘all of the rights’ or ‘all rights’, and even though it’s not a legal text, I’d still be happier if ‘rights’ were a bit more specific.
