Such written statement shall specify the basis of such opinion. After opportunity for hearing upon the objections specified in the written statement so filed, the Commission may, and if demanded by such trustee or by such applicants shall, enter an order either sustaining one or more of such objections or refusing to sustain any of them. If the Commission shall enter an order refusing to sustain any of such objections, or if, after the entry of an order sustaining one or more of such objections, the Commission shall find, after notice and opportunity for hearing, that all objections so sustained have been met, and shall enter an order so declaring, such trustee shall mail copies of such material to all such indenture security holders with reasonable promptness after the entry of such order and the renewal of such tender.

(c) Disclosure of information deemed not violative of any law 
The disclosure of any such information as to the names and addresses of the indenture security holders in accordance with the provisions of this section, regardless of the source from which such information was derived, shall not be deemed to be a violation of any existing law, or of any law hereafter enacted which does not specifically refer to this section, nor shall such trustee be held accountable by reason of mailing any material pursuant to a request made under subsection (b) of this section.
