On April 20, 2010, M. Catherine Santee, CH2M HILL Companies Ltd.’s Senior Vice President and Chief Financial Officer, informed the Board of Directors of her intention to step down as CH2M HILL’s Chief Financial Officer and assume the responsibilities of CH2M HILL Operations’ Finance Director.  Ms. Santee informed the Board that her decision to take on a different role within CH2M HILL and to relocate to Louisiana to be closer to her family was prompted by the needs of her family.  In a communication to our Board, CH2M HILL’s Chief Executive Officer, Lee A. McIntire, stated, “Catherine is an invaluable contributor to CH2M HILL and an important reason for our success as a Fortune 500 company.  We understand her decision and support her transition to the new role, where she will continue to make significant contributions in guiding the financial success of our operating units.  Catherine is a special person for all of us at CH2M HILL.”

Ms. Santee joined CH2M HILL in 1995 as Vice President and Chief Financial Officer for CH2M HILL’s Infrastructure and Environment Group.  She became the Chief Financial Officer for CH2M HILL Companies, Ltd. in 2008; and served on our Board of Directors from 2003 to 2006, and again from 2007 until present.

JoAnn Shea, CH2M HILL’s Vice President, Chief Accounting Officer and Controller will assume responsibilities as acting Chief Financial Officer effective May 15, 2010.  Ms. Shea joined CH2M HILL in 1998 as an Assistant Controller, became CH2M HILL’s Controller in 2003, and CH2M HILL’s Chief Accounting Officer in 2006.

CH2M HILL will commence a national search for the new Chief Financial Officer effective immediately and will consider internal and external candidates, as has been our practice for all senior management roles.

Other information with respect to Ms. Santee and Ms. Shea may be found in CH2M HILL’s Proxy Statement for its 2010 Annual Meeting, as filed with the Securities and Exchange Commission on Schedule 14A (Commission File No. 000-27261), under the captions “Executive Officers” and “Change of Control Agreements,” which information is incorporated herein by reference.
