Mustang acquires automation engineering company

Wood Group's Mustang acquires Latin American automation engineering 
                              and consultancy company

HOUSTON, December 16, 2011 -Mustang, a Wood Group company, has acquired a
majority stake in ISI Solutions for an initial consideration of US$5.2 million.
ISI Solutions is a Latin American provider of automation and control
engineering and consulting services to the oil & gas, power and pipeline
industries in Latin America. The gross assets of ISI were $8.5m as at 31
December 2010.

ISI, which will be rebranded ISI Mustang, has approximately 240 employees in
six countries: Argentina, Bolivia, Chile, Colombia, Mexico and Peru. ISI
Mustang will operate within Mustang's Automation and Control (MAC) business and
will continue to be led by Pedro Santamaria and its existing management team.

The acquisition is a key strategic move for Mustang into the Latin American
automation and control market. With a core competency of providing automation
services to the pipeline sector, ISI complements MAC's business, which focuses
on refining, petrochemical and oil & gas production facilities.

"This is a strategic move to increase our automation and control capabilities
in Latin America," said Steve Knowles, president of Mustang. "ISI's strong
management team and proven track record provides Mustang with a robust platform
for growth across South America and in Mexico."

"ISI sought a strategic partner to pursue the larger and more complex
automation opportunities available in Latin America," said Pedro Santamaria,
ISI Mustang chief executive. "We are pleased to have found a parent with a
strong global network, similar values and a shared focus on customers,
employees and the community."
