Mr. Lou Waters, Sr.

Chairman of the Board

Mr. Ted Owen

President and Chief Executive Officer

Team Industrial Services, Inc.

Sugar Land, TX 77478

Dear Lou and Ted:

It is with great sadness that I resign effective today as a member of the Board of Directors of Team, Inc. My resignation does not involve a dispute of any nature involving the company or its operations, policies or practices.

Quanta Services, Inc. recently completed the acquisition of a company which generates competitive revenues in excess of the threshold contained in Section 8 of the Clayton Act. As a result, I cannot continue to serve on both boards.

I have enjoyed serving on the board immensely. Please convey to the rest of the board and the management team how much I have enjoyed working with them for the past twelve years. Many of the relationships I have made will be lifelong.

Thank you both for your personal kindness over the years. I wish you and the other board members much success in the years ahead.

Sincerely,

/s/ Vincent D. Foster

Vincent D. Foster
