Instructions For Stock Certificates With Restrictive Legends

Most of our share certificates issued before we became a public company contain restrictive legends. However, most of these shares are covered by a blanket legal opinion on file with our transfer agent that should enable the removal of those legends. To have the restrictive legend removed from share certificates, brokers must submit the original stock certificate(s), a letter of instruction and a Medallion Guaranteed stock power to our transfer agent, Wells Fargo, at the address below. Processing time should be 3-5 business days provided the request is submitted in good order. Any questions regarding removal of the restriction should be directed to Wells Fargo at 1-800-468-9716.
