The provisions of this chapter do not apply to emphyteutic leases, except as regards the revision of the rent. However, they shall apply, in the cases provided for in articles L. 145-1 and L. 145-2, to leases entered into by emphyteutic lessees, provided that the duration of the renewal granted to their sublessees does not have the effect of extending the occupation of the premises beyond the expiry date of the emphyteutic lease.
