1. The rights referred to in Article I shall include the basic rights
ensuring the author's economic interests, including the exclusive right
to authorize reproduction by any means, public performance and
broadcasting. The provisions of this Article shall extend to works
protected under this Convention either in their original form or in any
form recognizably derived from the original.
2. However, any Contracting State may, by its domestic legislation,
make exceptions that do not conflict with the spirit and provisions of
this Convention, to the rights mentioned in paragraph 1 of this
Article. Any State whose legislation so provides, shall nevertheless
accord a reasonable degree of effective protection to each of the
rights to which exception has been made.
