Where the lessee returns the object without observing the notice period or the deadline for termination, he is released from his obligations towards the lessor only if he proposes a new lessee who is acceptable to the lessor, solvent and willing to take on the lease on the same terms and conditions.
Otherwise, the lessee must continue to pay the rent until such time as the lease ends or may be terminated under the contract or by law.
Against the rent owing to him the lessor must permit the following to be brought into account:
any expenses he has saved, and
any earnings which he has obtained, or intentionally failed to obtain, from putting the object to some other use.
