R.C. § 1701.74
Committee Comment (2012)*
New division (B)(4) eliminates dissenters' rights in connection with an amendment to the articles if the shares of the corporation for which a shareholder would make a demand are listed on a national securities exchange and no proceedings are underway to delist the shares. The testing date for the listing status of the shares is the day immediately before the day of the vote, but if the event giving rise to dissenter's rights is an amendment to the articles under division (A)(1), the relevant date is the date when the amendment is effective.
