(a) Any tenant at the time of the preliminary notice grace period shall be entitled to have his lease extended, on the same terms and conditions as the immediately preceding lease, until the expiration of the grace period. Nothing in this subsection shall prevent the owner from increasing rent pursuant to § 7110(d) of this title.
(b) After receipt of the final notice, and upon 30 days' written notice to the owner, a tenant may without penalty terminate his existing lease; provided, however, that the owner shall receive a full month's rent for any partial month of tenancy.
