                       HOLDING IN FUSION OIL & GAS PLC                        
                                  AND CREST                                   
                                                             
Following the successful flotation and fundraising of Fusion Oil & Gas plc
('Fusion') and the commencement of trading of Fusion's shares on the
Alternative Investment Market ('AIM') today. Westmount Energy Limited
('Westmount') announces that following Fusion's placing of 30,000,000 new
Ordinary Shares with institutional and other investors, Westmount through its
wholly owned subsidiary, Westmount Resources Limited ('WRL') holds 20,000,000
Ordinary Shares representing 21.96% of the entire issued share capital of
Fusion and remains the largest shareholder in Fusion.

In addition WRL is entitled to exchange its holding of partly paid shares,
when paid up, for a further 500,000 Ordinary Shares in Fusion. Assuming all
such outstanding shares in issue are paid up in due course for Ordinary Shares
of Fusion, Westmount's holding in Fusion would be 20.68%.

Additionally, now that recent changes to Jersey Law permit electronic transfer
of shares, Westmount is taking steps to permit its shares to be issued in
uncertificated form and admitted to the CREST system. This procedure will
involve various changes to Westmount's Articles of Association and an
Extraordinary General Meeting of Shareholders will be convened shortly to
propose the appropriate resolutions.
