Dear Mr Marshall

Re:  The Groundell Trust  - Funding Commitment

On behalf of the above Trust, I am instructed to confirm the following :-

(1)  Subject to Government acceptance and verification of the contract
     documentation the Trust expects to be in a position to confirm the Funding
     timeframe on or before the 10th November 2000;
(2)  Subject to the above, the Trust will then be in a position to confirm the
     timing for funds movement.
(3)  At this stage, again subject to the parameters that will be set by the
     Authorities, the funding to your Corporation will be  $US10 million within
     this calendar year.

The above three items are for dissemination to your shareholders only, and not
for any further form of public information.

Because of sensitivity, particularly at this stage of the transaction, under NO
circumstances, is the name of Groundell Trust to be used.

FOR YOUR  WEB SITE:

"Funding for the Corporation , as previously negotiated, is tracking in
accordance with the critical time-flow provided by the Funders to us. At this
time, it is envisaged that the first substantial draw-down will be in hand
before the end of November 2000."

Yours faithfully
Signed " John M Murfitt "
John M Murfitt
General Counsel
