(1) Any owner of copyright in a work specified in this subsection or any public broadcasting entity may, within one hundred and twenty days after publication of the notice specified in this subsection, submit to the Copyright Royalty Tribunal proposed licenses covering such activities with respect to such works. The Copyright Royalty Tribunal shall proceed on the basis of the proposals submitted to it as well as any other relevant information. The Copyright Royalty Tribunal shall permit any interested party to submit information relevant to such proceedings. (2) License agreements voluntarily negotiated at any time between one or more copyright owners and one or more public broadcasting entities shall be given effect in lieu of any determination by the Tribunal: Provided, That copies of such agreements are filed in the Copyright Office within thirty days of execution in accordance with regulations that the Register of Copyrights shall prescribe. (3) Within six months, but not earlier than one hundred and twenty days, from the date of publication of the notice specified in this subsection the Copyright Royalty Tribunal shall make a determination and publish in the Federal Register a schedule of rates and terms which, subject to clause (2) of this subsection, shall be binding on all owners of copyright in works specified by this subsection and public broadcasting entities, regardless of whether or not such copyright owners and public broadcasting entities have submitted proposals to the Tribunal. In establishing such rates and terms the Copyright Royalty Tribunal may consider the rates for comparable circumstances under voluntary license agreements negotiated as provided in clause (2) of this subsection.

(c) The initial procedure specified in subsection (b) shall be repeated and concluded between June 30 and December 31, 1982, and at five-year intervals thereafter, in accordance with regulations that the Copyright Royalty Tribunal shall prescribe
