NEWS RELEASE:F R l M 14 2009For Release: May 14, 2009

Proserv Energy Awarded Turnkey GoM Project

Client: St Mary Land & Exploration

Location: Gulf of Mexico, Vermillion Area

Scope of Work: Abandonment and removal ofScope of Work: Abandonment and removal of platform, pipelines and wells destroyed during Hurricane Ike.

Contract Type: Fixed Price – Turnkey

Contract Characteristics:

•Proserv offered asset ownership, however the lease had expired. Therefore, the Operator retained ownership.

•Proserv has risk and responsibilities for planning, project management, and all costs,

•Project execution within MMS approved timelines.

•No recourse except for non-disclosed information.

Objective: Give the operator a risk-free alternative forObjective: Give the operator a risk free alternative for removing non-producing assets, freeing up capital and credit.

A C ?Are we Crazy?

The Answer depends on whether or not we know what we’re doing.

Our Experience:Our Experience:•More than 20 years in

the Gulf of Mexico

•Over 400 Decommissioning Projects Completed

•Strive for fit-for-purpose decommissioning solutions
