                       APPOINTMENT OF NEW CHIEF EXECUTIVE


Former McKinsey & Co associate partner Fernando Cesar Lunardini, aged 37, has
been appointed Chief Executive of AIM-listed Caldwell Investments Plc ('Caldwell
' or 'the Company') with effect from 22 June 2007. Caldwell recently announced
its intention to establish a biodiesel operation, producing and exporting crude
oil from jatropha plantations in Brazil. The Company has put a proposal to
shareholders to change its name to VIRIDAS PLC at its annual meeting on 27th
July 2007.

Mr Lunardini spent eight years of his career at McKinsey & Co, and was
previously at Gemini Consulting and Andersen Consulting. He holds an MBA from
INSEAD and gained a BSc in Metallurgical Engineering in Brazil. Whilst with
McKinsey, he spent many years building strategies for major multinational
companies in South America and in the USA, and led a year-long transformation
programme for a large South American fertilizer company defining its strategic
growth path. Since leaving McKinsey in 2006, he has become involved in
eco-related business developments in Brazil in the carbon and ethanol markets.
Speaking five languages, Mr. Lunardini, has contributed to the McKinsey
Quarterly and Harvard Business Review LA.

Mr Lunardini is also a director of Panozon Ambiental Ltda, a water treatment
company.

Save for the above, there is no further information required to be disclosed
under paragraph (g) of Schedule 2 of the AIM Rules.

Stanley Wootliff, Caldwell's Chairman, said: 'Fernando has many years'
consultancy experience and he and his team have prepared a detailed plan for the
production of crude jatropha oil. Caldwell intends to control all aspects of
production from developing the right varieties of jatropha plant, managing the
planting, the picking and the crushing operation. We have already selected flat
and fertile sites in Brazil for the mechanical planting of 200,000 jatropha
trees with the ultimate target of 100 million trees being grown on 33sq kms of
land. We are fortunate in bringing on-board a man with the appropriate
background and relevant industry contacts.'

Mr. Lunardini said 'I am very pleased to be in at the birth of a new growth
industry. Brazil is the right place to be, jatropha the right plant for
biodiesel and we have assembled the right expertise to make the project
successful.'
