Ann: Pfizer raises scheme consideration to A$0.208 per share, page-31

Got a fair bi of this bought in 8's keep getting calls to vote YES. I was going to say NO thinking there got to be more value in this if Pfizer can up the bit so much. As anyone knows, a corporate shark like Pfizer will never offer a company that's struggling financially anywhere near its true value also would not up the ante that much unless it has more value.
Anyways, does anyone know whats the last date Pfizer can pull out the offer?
