Acquisition of APA Petroleum Engineering Inc by RPS Energy Canada Ltd

01.02.07

APA Petroleum Engineering Inc (APA) and RPS Energy Canada Ltd (RPSEC) are pleased to announce that, with effect from 1 February 2007, APA has become part of RPSEC, and will be included in the Energy Division of RPS Group plc (RPS). APA will now trade as RPS-APA. The combined group will operate on a worldwide basis from regional offices in Canada, USA, Europe, SE Asia and Australia.

RPS considers APA to be one of the foremost consultancies of its kind in North America and this move, which comes in response to developing global market opportunities within the oil & gas and energy consulting sectors, adds significant world-class capability to the Energy Division of RPS. Both RPS Energy and APA have a reputation for providing flexible independent consultancy with an emphasis on developing long term relationships with their clients. This ethos will continue within, and be strengthened by, the combined organisation.

There are significant geographical and functional synergies between the two companies that will allow RPS Energy to ensure that both new and existing clients receive an enhanced and responsive service in respect of both specialist and integrated services. In particular, APA will strengthen and broaden the production, facilities and well engineering capability of RPS Energy, adding to the group's already broad range of capability in technical, commercial and advisory services. By bringing the organisations together under a common management and investment strategy, RPS Energy will be able to respond quickly to and effectively to the requirements of its worldwide clients.

The management teams of both organisations will remain with the businesses and contribute to its future success. Both RPSEC and APA place significant value on developing and maintaining an excellent relationship with their employees and consultants, and consider that the expanded group will provide new opportunities for its personnel on both project and career development levels, leading to increased value for clients.

This is an exciting time for APA; joining RPS Energy Canada Ltd provides a platform for further development and success at both company and personal levels.
