Dear Superior Employees,

It is quite rewarding to reflect on the recent accomplishments of our organization. During the past year, we have maintained a strong balance sheet and continued to grow our business. Thus far in 2011 we have had three very successful quarters, attributable to ongoing strength in activity levels in the U.S. land markets, consistent execution of our international growth strategy, the steady increase in Gulf of Mexico activity, and the dedication and hard work of each and every employee.

Perhaps the most exciting day of 2011 was the announcement of our intended merger with Complete Production Services, Inc. Based on the latest feedback from government regulators, we hope to close the merger as soon as the end of January 2012 and, as promised, we will keep you informed of any new developments. Your support and continued dedication to our company during this time has been invaluable.

We have maintained positive momentum, and I believe we are well positioned to make 2012 another strong year of achievement. As part of the Superior culture, we are all committed to our jobs and our customers, and I am proud to be a part of such an impressive organization.

I want to personally thank each and every one of you for all your efforts. As always, if you would like to contact me directly with any questions or concerns, you can reach me at 281-999-0047 or dave.dunlap@superiorenergy.com.

I wish you a very happy, healthy and safe holiday season.

Sincerely,
