So where did you read anything about how much money erhc spent? What I saw was them saying they didn't have money to even keep their filings up to date as required.
Yes, today's trading should be interesting. Let's see how much buying and how high the price is lifted from this news (which happens to be a couple of weeks old). Price and volume should show how much investors think any deal will happen, how much it might be worth, and whether they think erhc's excuse will keep its shares from being revoked.
Listen to the message of the market.
