                  COLLABORATIVE MARKETING AGREEMENT WITH HATCH


Virotec International Ltd (ASX/AIM: VTI) and Hatch Associates Pty Ltd are
pleased to announce that they have signed a collaborative marketing agreement.
The primary objective of this agreement is to facilitate the marketing and
promotion of Virotec's BASECON(TM) Technology to the alumina industry.

Hatch (www.hatch.ca) is a global engineering and consulting firm with experience
and contacts in the mining, minerals and metals industries.  In particular,
Hatch is currently a member of a number of engineering alliances with major
alumina producers, and is involved in the design and feasibility study for a
range of new and upgraded alumina refinery projects world wide.

Under the terms of the agreement, Virotec grants to Hatch an exclusive right to
market the BASECON(TM) Technology in proposals, pre-feasibilities,
feasibilities, and engineering designs to a number of alumina producers and
alumina refinery projects as specified in the agreement.  The scope of the
agreement can be expanded to include other projects that Hatch are involved with
and where the BASECON(TM) or Bauxsol(TM) Technologies have application.  Virotec
and Hatch will work together with respect to the projects, with Hatch managing
the projects, including any implementation or application of the Technologies if
the proposals are successful.  The agreement is for ten years and may be
extended by mutual agreement.

As announced by Virotec on 30 August 2002, the BASECON(TM) Technology is a
significant breakthrough that has the potential to benefit the alumina industry
throughout the world.  BASECON(TM) Technology can be applied as part of the
Bayer process, enabling the alumina industry to produce an environmentally
benign waste by neutralising the high caustic component of red mud.  It can also
be applied to the caustic residue that is stored in containment ponds thereby
contributing to complete environmental remediation.

Virotec's Chairman, Brian Sheeran commented "This is very significant step in
the commercialisation of Virotec's technologies and in particular a technical
and economic endorsement of the BASECON(TM) Technology.  Hatch have a very
strong reputation in the alumina industry throughout the world, and have the
expertise and capability to successfully assist Virotec in the marketing of the
BASECON(TM) Technology.  Hatch service a number of existing producers in the
alumina industry and are actively involved in the design and
construction/refurbishment of new refineries.  Hatch have recognised the
importance of the Basecon(TM) Technology to the industry particularly as it
strives to achieve a sustainable future.  We look forward to a long and
successful association."

Chris Twigge-Molecey, Managing Director, Technologies of Hatch stated that 
"Hatch is very pleased to be working with Virotec to bring technological
solutions to our clients for both red mud re-use and industrial remediation.
Virotec's renowned technical expertise will complement Hatch's and bring
significant added value to our clients going forward".
