Acquisition

On February 21, 2013, LinnCo and Berry Petroleum Company (“Berry”) announced they had signed a definitive merger agreement under which LinnCo would acquire all of the outstanding common shares of Berry. The transaction has a preliminary value of approximately $4.3 billion, including the assumption of debt, and is expected to close by June 30, 2013, subject to approvals by Berry and LinnCo shareholders, LINN Energy’s unitholders and regulatory agencies.

Under the terms of the agreement, Berry’s shareholders will receive 1.25 of LinnCo common shares for each Berry common share they own. This transaction, which is expected to be a tax-free exchange to Berry’s shareholders, represents value of $46.2375 per common share, based on the closing price of LinnCo common shares on February 20, 2013. Upon completion of the merger, LinnCo will contribute Berry assets to LINN Energy in exchange for LINN Energy units.
