Ohio Revised Code Title XVII. Corporations Partnerships § 1707.43

(A) Subject to divisions (B) and (C) of this section, every sale or contract for sale made in violation of Chapter 1707. of the Revised Code, is voidable at the election of the purchaser. The person making such sale or contract for sale, and every person that has participated in or aided the seller in any way in making such sale or contract for sale, are jointly and severally liable to the purchaser, in an action at law in any court of competent jurisdiction, upon tender to the seller in person or in open court of the securities sold or of the contract made, for the full amount paid by the purchaser and for all taxable court costs, unless the court determines that the violation did not materially affect the protection contemplated by the violated provision.

(B) No action for the recovery of the purchase price as provided for in this section, and no other action for any recovery based upon or arising out of a sale or contract for sale made in violation of Chapter 1707. of the Revised Code, shall be brought more than two years after the plaintiff knew, or had reason to know, of the facts by reason of which the actions of the person or director were unlawful, or more than five years from the date of such sale or contract for sale, whichever is the shorter period.

(C) No purchaser is entitled to the benefit of this section who has failed to accept, within thirty days from the date of such offer, an offer in writing made after two weeks from the date of the sale or contract of sale, by the seller or by any person that has participated in or aided the seller in any way in making the sale or contract of sale, to take back the security in question and to refund the full amount paid by the purchaser.
