(b) For sixty days after delivery or mailing of the notice described in subsection (a), the person required to give the notice shall offer to convey each unit or proposed unit occupied for residential use to the tenant who leases that unit. If a tenant fails to purchase the unit during that sixty day period, the offeror may not offer to dispose of an interest in that unit during the following one hundred eighty days at a price or on terms more favorable to the offeree than the price or terms offered to the tenant. This subsection does not apply to any unit in a conversion building if that unit will be restricted exclusively to nonresidential use or the boundaries of the converted unit do not substantially conform to the dimensions of the residential unit before conversion.
(c) If a seller, in violation of subsection (b), conveys a unit to a purchaser for value who has no knowledge of the violation, the recordation of the deed conveying the unit or, in a cooperative, the conveyance of the unit, extinguishes any right a tenant may have under subsection (b) to purchase that unit if the deed states that the seller has complied with subsection (b), but the conveyances does not affect the right of a tenant to recover damages from the seller for a violation of subsection (b).
(d) Nothing in this section permits termination of a lease by a declarant in violation of its terms.
