(D) within forty-five days after the end of each calendar quarter, an owner or officer of the cable system executes an affidavit attesting (i) to the steps and precautions taken to prevent duplication of the videotape, and (ii) subject to clause (2), to the erasure or destruction of all videotapes made or used during such quarter; and (E) such owner or officer places or causes each such affidavit, and affidavits received pursuant to clause (2) (C), to be placed in a file, open to public inspection, at such system's main office in the community where the transmission is made or in the nearest community where such system maintains an office; and (F) the nonsimultaneous transmission is one that the cable system would be authorized to transmit under the rules, regulations, and authorizations of the Federal Communications Commission in effect at the time of the nonsimultaneous transmission if the transmission had been made simultaneously, except that this subclause shall not apply to inadvertent or accidental transmissions. (2) If a cable system transfers to any person a videotape of a program nonsimultaneously transmitted by it, such transfer is actionable as an act of infringement under section 501, and is fully subject to the remedies provided by sections 502 through 506 and 509, except that, pursuant to a written, nonprofit contract providing for the equitable sharing of the costs of such videotape and its transfer, a videotape nonsimultaneously transmitted by it, in accordance with clause (1), may be transferred by one cable system in Alaska to another system in Alaska, by one cable system in Hawaii permitted to make such nonsimultaneous transmissions to another such cable system in Hawaii, or by one cable system in Guam, the Northern Mariana Islands, or the Trust Territory of the Pacific Islands, to another cable system in any of those three territories, if-- (A) each such contract is available for public inspection in the offices of the cable systems involved, and a copy of such contract is filed, within thirty days after such contract is entered into, with the Copyright Office (which Office shall make each such contract available for public inspection); and (B) the cable system to which the videotape is transferred complies with clause (1)(A), (B), (C)(i), (iii), and (iv), and (D) through (F); and (C) such system provides a copy of the affidavit required to be made in accordance with clause (1)(D) to each cable system making a previous nonsimultaneous transmission of the same videotape. (3) This subsection shall not be construed to supersede the exclusivity protection provisions of any existing agreement, or any such agreement hereafter entered into, between a cable system and a television broadcast station in the area in which the cable system is located, or a network with which such station is affiliated.
