Sorry but there is a requirement to provide the details of the definitive material agreement. ERHE has already made the determination that is material because they filed an 8K. Furthermore, the SEC suggests filing the agreement with the 8K so as to not under-report the event. However they do give you the option to file it with your next 10Q or 10K. The question is why would you wait? A good CEO would err on the side of more disclosure and more openness, not less.
There is a remote possibility that there is something that is confidential within the PSC but my guess is there isn't. And even if there was, the non-confidential details could have and should have been provided. I will bet that the PSC in its entirety will be published in the next 10Q because I believe it is a requirement. If so, there is no reason why it couldn't and shouldn't have been done NOW.
