OKLAHOMA CITY — Devon Energy Corporation (NYSE: DVN) today announced the elections of two corporate officers.

Jeff Agosta, 42, has been appointed to the position of executive vice president and chief financial officer. Agosta joined Devon in 1997 and has served in various capacities with increasing responsibility. Most recently, he served as Devon’s senior vice president – corporate finance and treasurer. Prior to joining Devon, Agosta was with the management consulting firm of D. R. Payne & Associates and KPMG LLC. He holds a Bachelor’s Degree in Accounting from the University of Oklahoma and is a Certified Public Accountant.

“Jeff Agosta’s extensive experience in accounting and corporate finance clearly positions him as an ideal candidate for this role,” said John Richels, Devon’s president. “It is gratifying to have such a talented individual available within Devon to move into this important position.”

Jeff Ritenour, 36, has been promoted to the position of senior vice president, corporate finance.
