acts or things which may be unlawful, or the violation of any
of the rights of such obligee of said authority.

18. An authority shall have power by its resolution, trust
indenture, mortgage, lease or other contract to confer upon
any obligee holding or representing a specified amount in
bonds, or holding a lease, the right (in addition to all rights
that may otherwise be conferred), upon the happening of an

diction:

(a) To cause possession of any housing project or any part
thereof to be surrendered to any such obligee.

(b) To obtain the appointment of a receiver of any hous-
ing project of said authority or any part thereof and of the
rents and profits therefrom. If such receiver be appointed, he
may enter and take possession of such housing project or any

arising therefrom, and shall keep such moneys in a separate

the obligations of said authority as the court shall direct.

(c) To require said authority and the commissioners thereof
to account as if it and they were the trustees of an express

19. All real property of an authority shall be exempt from
levy and sale by virtue of an execution, and no execution or
other judicial process shall issue against the same nor shall
any judgment against an authority be a charge or lien upon
its real property; provided, however, that the provisions of
this section shall not apply to or limit the right of obligees
to foreclose or otherwise enforce any mortgage of an author-
ity or the right of obligees to pursue any remedies for the
enforcement of any pledge or lien given by an authority on its
rents, fees or revenues; and provided, further, that the pro-
visions of this section shall not deprive any city or county
of its right to collect any service charge agreed upon in lieu
of taxes in the same manner as all such taxes are now, or
may hereafter be, collectible under the laws of this State
and of said cities or counties.
