Penn West announces appointment of new President and Chief Executive Officer, operational improvement and capital efficiencies drive, initiation of corporate strategic review and a change to its dividend policy

Appointment of new President and Chief Executive Officer

CALGARY, June 4, 2013 /CNW/ - PENN WEST PETROLEUM LTD. (TSX - PWT; NYSE - PWE) ("PENN WEST" or "the Company") announced today that Murray Nunns, President and Chief Executive Officer, has informed the Board of Directors of his intention to retire from Penn West effective July 1, 2013 after serving the Company for more than 8 years.

"Mr. Nunns has made a significant contribution to Penn West since he joined Penn West's Board in 2005," said Rick George, Chairman of the Board. "The Board would like to thank Murray for his contributions to the Company both as a Board member and most recently as the President and Chief Executive Officer.  He has had a distinguished career lasting more than 30 years in the oil and gas industry and we wish him well in his retirement."  Concurrent with his departure, Mr. Nunns will also be resigning from the Board of Directors of Penn West.

David Roberts, former Executive Vice President and Chief Operating Officer of Marathon Oil Corporation, has agreed to terms of employment and will begin his new role as President and Chief Executive Officer commencing June 19, 2013.  Dave brings more than 30 years of operational experience in the upstream oil and gas business and his knowledge and successes on such a very large scale make him a welcome addition to the senior management team at Penn West.  The Board intends to appoint Mr. Roberts to the Board on commencement of his employment.

Mr. Roberts also served as Marathon's Executive Vice President Upstream for a number of years after joining Marathon in 2006 as Senior Vice President Business Development. He previously served as Executive Vice President/Managing Director for BG Group plc with responsibility for Asia and the Middle East. Prior to joining BG Group, he served as advisor to the Vice Chairman of ChevronTexaco Corporation from 2001 to 2003, where he provided strategic and operational advice to executive management regarding the company's upstream operations.  Dave built his early skills with Texaco, where he held a number of key operational and strategic planning roles over an 18 year period.

"Dave brings a unique blend of operating field experience, strategic thinking at a very high level as well as knowledge of critical new industry technology.  The entire Board is looking forward to working with Dave to drive Penn West forward," said George.

Operational Improvements
The Company, under a new Board and a new CEO, will focus on operating the business in a more efficient manner, significantly reducing General and Administrative expenses as well as field operating costs.  Mr. George commented, 'We will be looking for a huge step change in both where capital is spent as well as the efficiency of each dollar invested".  The Company will focus its efforts on execution across the board, maximizing the use of its mid-stream assets and improving the netbacks it receives on each barrel produced.

"We will be reviewing all staffing levels and while these are never easy decisions, and we appreciate the efforts of each and every employee, we expect to start by reducing staffing levels by 10 percent over the next few weeks," George said.

Corporate Strategic Review
Penn West's Board of Directors will form a Special Committee to explore strategic alternatives.  The Special Committee will consider all alternatives to increase shareholder value, including strategic financing alternatives, asset divestments, joint ventures and/or other business combinations.  Although strategy review is always an ongoing activity for all companies, we expect this concentrated effort will be completed by year end.  "Penn West has many high quality assets but the Company has yet to unlock their complete value.  The Board is focused on maximizing value for all shareholders," said Mr. George.

Dividend Reduction to Strengthen Financial Flexibility
Penn West also announces that its Board has approved a change to its dividend.  Effective for its third quarter, Penn West's quarterly dividend will be reduced to $0.14 per common share from $0.27 per common share.  This measure will provide Penn West with increased financial flexibility, and a sustainable dividend, as it continues to improve operating performance.  The second quarter dividend of $0.27 per common share will be paid as declared on May 1, 2013 to shareholders of record on June 28, 2013.

Penn West confirms that its full year production and capital guidance remain unchanged.

Penn West shares are listed on the Toronto Stock Exchange under the symbol PWT and on the New York Stock Exchange under the symbol PWE.
