(2) Offers, sells or purchases a security by means of any untrue statement of a material fact or any omission to state a material fact necessary in order to make the statement made, in the light of the circumstances under which they are made, not misleading (the buyer or seller not knowing of the untruth or omission), and who does not sustain the burden of proof that the person did not know, and in the exercise of reasonable care could not have known of the untruth or omission, is liable to the person buying or selling the security from or to him or her, who may sue either at law or in equity to recover the consideration paid for the security, together with the interest at the legal rate from the date of payment costs, and reasonable attorneys' fees, less the amount of any income received on the security, upon the tender of the security, or for damages if he or she no longer owns the security.
