(2) that the telephone corporation bear the entire cost of the installation, operation or removal of such facilities; and

(3) that the telephone corporation agree to indemnify the landlord of the commercial property for any damage caused by the installation, operation or removal of such facilities;

(b) demand or accept payment from any commercial tenant, in any form, in exchange for permitting telephone corporation services on or within such commercial property or premises, or from any telephone corporation in exchange therefor in excess of any amount which the commission shall, by regulation, determine to be reasonable; or
