Ann: Half Yearly Report and Accounts , page-6

Looks like ESN might need -
Substantial revenue - $100,000.00+ per month
or
More notes issued?
or
Notes converted to reduce debt (dilution)
Options (.001c) (100,000,000)per month excised to put $ in the kitty (dilution)

This might all come down to how good a friend the note/option holders are?
Options could be converted and sold at .001c only loss would be brokerage, IF previous notes/options were sold in the .002 to .006 range they may have enough profit to justify doing this.

The other concern is the decrease in Net Tangible Assets from -.04c to -.07c (negative .07c) per share

There are quite a few things that cuold be done with the notes/options.
