(a) Grantees eligible; priorities; applicability of deduction, financing and indemnity provisions
The Commission is authorized at Los Alamos to grant to occupants project-connected persons, and persons residing in the community both at the time of offering of an apartment house for sale and for the preceding six months, and to any of the foregoing persons acting together, such priority interests and priority rights for the purchase of the apartment house as the Commission determines to be fair and reasonable: Provided, That a first priority right to purchase may be granted only to an occupant or a group of occupants, or an assignee (whose membership or ownership is composed of occupants, or project-connected persons, or persons residing in the community both at the time of offering of an apartment house for sale and for the preceding six months, or any of the foregoing persons) of the priority interests of such occupants, who or which has obtained the priority interest of at least 60 per centum of the occupants of the apartment house: Provided further, That a second priority right to purchase may be granted only to an entity whose membership or ownership consists of occupants, or project-connected persons, or persons residing in the community both at the time of offering of an apartment house for sale and for the preceding six months, or any of the foregoing persons (provided that such entity has obtained the priority interest of at least one occupant), and whose membership or ownership equals in number, and occupies or agrees to occupy, at least 70 per centum of the housing units in the apartment house. The 15 per centum deduction specified by section 2325(a) of this title, the deduction provided by section 2326(d) of this title, the financing provisions of section 2362 of this title, and the indemnity provided by sections 2363 to 2366 of this title shall be applicable to such priority sales of apartment houses. Priority interests granted by the Commission under this section shall be transferable as the Commission may by rule or regulation prescribe, but no priority right to purchase shall be transferred except as provided by section 2333 of this title.

(b) Leasing arrangements by non-participants in apartment house sales; assumption of lessor's obligations
Any occupant who does not participate in the purchase of an apartment house with respect to which a priority right to purchase has been granted shall be entitled, at the time of sale by the Commission, to a lease for occupancy of his housing unit for a period not to exceed fifteen months from the date the property was first offered for sale: Provided, That the occupant makes application for such a lease within 30 days of the grant of such priority to purchase. In selling any apartment house with respect to which lease executed under this section is in effect, the Commission is authorized to provide for the purchaser to assume any or all obligations of the lessor. The Commission in such event shall guarantee the lessee's performance of the lease.

(c) Eligibility to participate in priority purchase
Persons who have purchased, either individually or jointly with other persons, a single-family house or duplex house (or a single-family unit in a duplex house) at Los Alamos pursuant to a priority right under this chapter shall not be eligible to participate in the priority purchase of an apartment house.

(d) Rules and regulations
The Commission is authorized to prescribe by rule or regulation such other conditions as it may find necessary or desirable for qualification of priority interests and rights for the purchase of an apartment house.
