sower,
I think Calypte has collected at least some good arguments during the last couple of months for the AMEX issue (financing, firm deal and first significant sales for oral test, the USAID waiver list for the blood test). Arguments they have not had in February and March when they met with AMEX and the deadline for listing/delisting was set. Hopefully sFDA will respond also with something positive until month's end.
The question will be if AMEX looks strictly on the self-imposed rules or if they see this rather as a political or business decision. I think they like to keep as many companies as possible as long as those companies have some promise and do not ruin the reputation of AMEX more than necessary. I don't think that Calypte can be filed into the latter category.
Anyway, AMEX listing does not matter really (to me), it is important that the company is progressing and executing successfully the business plan. Since Roger is at the helm the company did very well in collecting the necessary milestones. Every piece takes its time but there is constant solid progress now. This is about getting the pieces together, one after the other.
