"I understand your reluctance to contact ERHC directly but maybe there can be a way to encourage some announcement....For example:
Hey Pete, Its Krombacher and major shareholder for your company..ERHC. I am not calling for any inside information from you but am calling to encourage you to publish "Something" that all shareholders know the company is still alive and pursuing existing deals with Total and / or Kosmos. This doesn't have to violate any Nondisclosure agreements with existing companies. Anything would be appreciated."
