Given how volatile the share price is (see speed at which it climbed from March levels), if they had closed the $0.70 PIPE, issued a new prospectus and offered shares at $3, only to see the share price drop back to $1, how much luck do you think they'd have had raising the funds?
$0.70 is just fine. Dec 2009 PIPE had people lining-up to get shares at $0.80 as the stock price climbed through $5. You cannot time these things.
Offering shares at a discount is better than not being able to raise the funds required.
Now we wait to see what the funds are for!
