From Turley intro:

Warrants Repurchased. By the time of the shareholders’ meeting we will have bought back all the remaining outstanding warrants held by Lincoln Ventures. This action, which we announced on July 24, eliminates the last of the warrants held by Swartz and Lincoln since they became long-term supporters and shareholders of Patriot Scientific.
