LINN Energy LLC Senior Vice President and General Counsel Charlene Ripley turned to lawyers from Latham & Watkins for the Houston company’s pending acquisition of Berry Petroleum Co. in a deal structured as a stock-for-stock merger and valued at $4.3 billion.

Denver-based Berry is using lawyers from Wachtell, Lipton, Rosen & Katz.

On Feb. 21, LINN, LinnCo — which was created to help LINN raise equity capital to make acquisitions — and Berry announced a definitive merger agreement calling for LINN and LinnCo to acquire all of Berry’s outstanding shares for $4.3 billion, including assumed debt.

Under the deal structure, Berry will merge with LinnCo and then LINN will acquire the Berry assets.

LINN, a master limited partnership, is an oil and gas development company, and Berry is an independent oil and natural gas production company.

The agreement was approved by boards of directors of LINN, LinnCo and Berry. The deal is expected to close by June 30, pending customary closing conditions, including Hart-Scott-Rodino Antitrust approval.

Prior to approving the definitive agreement, the boards of LINN and LinnCo each formed conflicts committees. Akin Gump Strauss Hauer & Feld represents the LINN conflicts committee, and Locke Lord represents the LinnCo conflicts committee.
