Wood Group Makes US$140m Move In Canadian Oil Sands                               

A subsidiary of John Wood Group PLC ("Wood Group") has agreed to acquire IMV
Corporation ("IMV") for an initial cash consideration of C$131m (US$140m). The
acquisition is expected to be completed by the end of November. There will be
three further cash payments due in the period to 2014 based on the future
performance of IMV. It is expected the acquisition will be earnings enhancing
from 2008 onwards.

IMV, owned by its management and employees, provides engineering, procurement
and construction management ("EPCM") services to the Canadian oil and gas
exploration and production sector, and is a market leader in EPCM services for
in-situ oil sands developments. It has a workforce of around 650 people and is
headquartered in Calgary, Alberta. Continuation of the existing management
team, including founder and President Ivan Velev, is planned. IMV had profits
before tax of C$21.6m (US$23.1m) for the year to August 2007.

The acquisition of IMV, one of Canada's top three engineering companies for
in-situ heavy oil production projects, is a key strategic move for Wood Group
into the Canadian heavy oil market. Canada has over 180 billion barrels of
proven oil reserves, making it the second largest source of oil reserves in the
world. Over 173 billion barrels are heavy oil reserves in Alberta, production
of which is expected to grow from an average 1.1 million barrels per day in
2006 to 3.5 million barrels per day by 2020. It is estimated that over 80
percent of the heavy oil reserves are too deep to mine and will require in-situ
development.

"This is a significant strategic step in developing a strong position in EPCM
services for the Canadian heavy oil market," said Mike Straughen, Group
Director and Chief Executive of Wood Group's Engineering activities. "IMV's
strong management team and proven track record of leading expertise for in-situ
steam-assisted heavy oil developments are an excellent complement to Wood
Group's existing engineering businesses. IMV will continue to operate as a
stand-alone business, satisfying the needs of its existing customers and
building on its leading position for in-situ heavy oil projects. In addition,
IMV will work closely with other Wood Group engineering companies, including
Mustang and J P Kenny, to help grow the Group's engineering activity in the
heavy oil, Arctic, upgrading/downstream and trunkline sectors."

Ivan Velev, IMV President, said "We are pleased to have this opportunity to
join Wood Group, a company that shares our cultures and values. IMV has
achieved strong growth over recent years, and we anticipate that the healthy
heavy oil market, momentum in our business and the support of Wood Group will
allow our growth to continue."
