Admission to AIM

Zareba PLC
19 April 2006


         Quadrise Fuels International plc ('Quadrise' or 'the Company')
                              formerly Zareba plc

                              First Day of Trading

The Board of Quadrise is pleased to announce that, earlier today, the enlarged
share capital of the Company was admitted to trading on AIM and accordingly, the
acquisition of Quadrise International Limited by Zareba plc in a reverse
takeover has been completed.

The ordinary shares of Quadrise will trade under the current TIDM  of 'ZBA'
until the close of trading today and, thereafter, under the TIDM 'QFI'.

Since the publication of the admission document in March 2006, the Company is
pleased to be able to report progress in the development of the business.

Our Canadian  associate, Quadrise Canada Fuels Systems Inc., has closed its
first commercial scale contract for the manufacture and use of MSAR fuel for
steam generation in a new heavy oil field production development project in
Alberta and has further projects under active negotiation.

Our affiliate, Quadrise Fuels US LP, has been formed recently in Delaware, USA
and initial financing for the US activity is planned for the second quarter of
2006. Preliminary negotiations have started on two potential offshore
manufacturing sites to supply MSAR fuels for the US market.

Concept design and costing for the Quadrise on-site heavy oil separator has now
been completed by an international engineering contractor and cost estimates are
within expectations. The Company is now well placed to finalise offer terms and
progress negotiations on processing and supply contracts currently under
discussion.

Ian Williams, Executive Chairman, commented, 'The completion of the reverse
takeover  represents a significant milestone for Quadrise and our shareholders.
We now have the resources and the capability to accelerate the commercial
application of MSAR fuels technology and aggressively pursue our early
development objectives.

We are confident that the Quadrise MSAR fuels business will create substantial
value owing in part to the economic benefits it offers to the thermal power
generation industry. Conversion from certain traditional hydrocarbon feedstocks
to MSAR fuels will also contribute to lower emissions.'

Bill Howe, Chief Executive, commented, 'Our Quadrise MSAR fuels business has
substantial global market potential. This transaction and the support of
shareholders position the Company to actively pursue partnerships in new
markets while also moving to close deals currently in varying stages of
negotiation.

Strong growth in international electrical power demand is set to continue. We
have the ability to offer very meaningful savings in thermal power generation
costs while also adding to the supply of valuable light oils for transportation
fuels.

We hope to be informing shareholders of further progress over the course of the
coming year.'

Notes to Editors:

- Quadrise was admitted to trading on AIM on 19 April 2006 following a
reverse takeover transaction.

- The Company holds a portfolio of managed, affiliate and associate
interests all of which are engaged in developing business activities associated
with the manufacture and marketing of Quadrise MSAR fuels.

- MSAR is a liquid fuel consisting of very fine oil particles
dispersed in a water carrier effectively producing a pre-atomised fuel. This
enhances concepts previously used in emulsified fuels, enabling superior carbon
burnout, improving thermal efficiency and reducing emissions.

- Quadrise has access to an in-house team of commercial and technical
experts who are experienced in the oil and energy business with contracted
specialist consultants who are experts in the energy, oil and power generation
sectors and in the specialised field of emulsion fuels processing, marketing and
combustion.

- Quadrise has access to opportunities through the established
relationships in the energy and oil industries and markets world wide of
Masefield Energy Holdings AG, its largest shareholder. It can also draw on
specialist services from group affiliates, on arms' length market terms,
covering oil procurement and operations, price and freight risk management,
transaction financing and other trading related activities.

- By using only the very heavy residues derived from processed crude
oils, the use of Quadrise MSAR fuels enables the release of the valuable
lighter oil fractions for processing into high value transportation fuels like
diesel and jet fuels.
