Dear Superior Employees,

I am pleased to report that our joint proxy statement/prospectus for consideration of the merger by both our stockholders and those of Complete has been declared effective by the Securities and Exchange Commission and is being mailed to all stockholders in order to solicit their vote to approve the merger and related transactions. This important step brings us another step closer in the process of merging our two companies. The next major step will be to hold special stockholders’ meetings on February 7th . During these meetings, the stockholders of both companies will vote on the proposed merger and related transactions. Assuming the required stockholder votes are obtained, we intend to close the merger as soon as possible after the stockholders’ meetings.

I want to thank all of you for conducting business as usual during this time and for continuing to focus on service to our customers and workforce safety, both of which are critical. Again, 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.
