The B warrants are currently some way from being in the money but if even some of the less optimistic predictions are correct we could see these and perhaps some of the other warrants having some value.

Current exchange rate is nearly exactly 58p per dollar. This gives the following figures:
Warrant($) Exercise price(£) Compulsory exercise price(£)
B 1.50 0.87 1.30
C 2.00 1.16 1.74
D 2.50 1.45 2.17
E 5.00 2.90 4.35
F 10.00 5.80 8.70
