A stipulation by which the author undertakes to grant a preferential right to a publisher for the publication of his future works of clearly determined genres is lawful.
This right is limited for each genre to five new works from the day of signature of the publishing contract concluded for the first work or to the author’s production completed within a period of five years from the same day.
The publisher must exercise the right granted to it by notifying the author of its decision in writing within three months from the day on which the author submits each final manuscript.
When the publisher benefiting from the preferential right has successively refused two new works presented by the author in the genre determined in the contract, the author may immediately and as of right resume his freedom with regard to future works he produces in this genre.
He must, however, in the event that he has received his future works from advances from the first publisher, make prior reimbursement of these.
