HOUSTON - Mustang International, LP, part of international energy services
company John Wood Group PLC ("Wood Group"), has agreed to acquire a majority
interest in Al-Hejailan Consultants' business through a newly established joint
venture, Mustang Al-Hejailan Engineering. Al-Hejailan Consultants, which is

the remaining interest. Upon completion later this year, Mustang Al-Hejailan
Engineering will provide engineering and project management services to Saudi
Arabia's oil & gas and chemical industries.

"The formation of Mustang Al-Hejailan Engineering gives us the opportunity to
create a world-class international engineering capability in Saudi Arabia by
adding highly experienced project management and engineering resources from
Mustang to Al-Hejailan Consultants'existing capability and excellent project
delivery," said Steve Knowles, president of Mustang. "We look forward to this
strategic combination of staff and capabilities, which will enable us to
deliver a sustainable project management, engineering, procurement, and
construction management (EPCM) business in Saudi Arabia, home to the largest
oil reserves in the world."

Mustang is one of the world's leading oil & gas engineering companies,
providing project management, conceptual and detailed engineering, and
construction management services. Mustang brings a track record of successful
worldwide delivery of large, complex offshore and onshore oil & gas, refining,
and petrochemical projects. The formation of Mustang Al-Hejailan Engineering
further expands Mustang's presence in the Middle East region, following the
establishment of an office in Abu Dhabi earlier this year.

Al-Hejailan Consultants, based in Al-Khobar, provides engineering and project
management consultancy services to a wide range of markets, including oil &
gas, petrochemical, infrastructure, and power within Saudi Arabia. The company
employs a multi-disciplinary staff of 150 personnel, including engineers,
project managers, designers, schedulers and other engineering support, and is a
general engineering services (GES) contractor to Saudi Aramco.

Faisal Al-Hejailan, president of Al-Hejailan Consultants, sees this new company
as "an important opportunity to enhance our services in the Kingdom of Saudi
Arabia through our association with Mustang and it is consistent with Aramco's
recently announced strategic plan for local GES contractors to partner with
international companies. Our partnering with Mustang will also bring to Saudi
Arabia a considerable engineering capability in the field of chemicals and
petrochemicals to address future plans of Sabic and the Royal Commission in
Jubail and Yanbu."
