Provided, however,
The issuer's duty to file any reports required under section 13(a) shall be suspended immediately upon filing a certification on Form 15; Provided, however, That if the certification on Form 15 is subsequently withdrawn or denied, the issuer shall, within 60 days after the date of such withdrawal or denial, file with the Commission all reports which would have been required had the certification on Form 15 not been filed. If the suspension resulted from the issuer's merger into, or consolidation with, another issuer or issuers, the certification shall be filed by the successor issuer.
