Dr. Schewe commented, "The VIASPACE Board and Management have been extremely pleased with the performance of VIASPACE since becoming a free-standing company on October 1, 2012. At that time, we announced a 6-month lock-up of insider share sales. Given the pace of our corporate progress and the momentum that we have achieved, we felt it important to continue the lock-up for another 90 days as we work hard to continue to increase the scope of our general shareholder base of investors. In addition, Dr. Kukkonen has two significant foreign trips to meet with clients in April and we are looking forward to sharing the news of those trips and providing exciting updates on existing projects in the near future."
