Preferred Stock, Dividend Payment Terms | declared a dividend of one preferred share purchase right for each outstanding share of BioSig’s common stock to stockholders of record on July 27, 2020, and one right will be issued for each new share of common stock issued thereafter. Each right will initially trade with common stock, and will allow its holder to purchase from BioSig one one-thousandth of a share of Series F Junior Participating Preferred stock | ||||||||||||

Preferred Stock, Voting Rights | In the event that a person or group acquires beneficial ownership of 12% or more of BioSig’s then outstanding common stock, subject to certain exceptions, each right would entitle its holder (other than such person or members of such group) to purchase additional shares of BioSig’s common stock having a market value of two times the exercise price of the right. In addition, at any time after a person or group acquires 12% or more of BioSig’s outstanding common stock (unless such person or group acquires 50% or more), the Board may exchange one share of BioSig’s common stock for each outstanding right (other than rights owned by such person or group, which would have become void). The Rights Plan could make it more difficult for a third party to acquire control of BioSig or a large block of our common stock without the approval of our board of directors. The rights will expire on July 13, 2021, unless terminated earlier by our board of directors | ||||||||||||
