Baker Botts represents Regency Energy Partners of Dallas in its pending acquisition of PVR Partners in an oil-and-gas deal valued at about $5.6 billion.

PVR, of Radnor, Pa., turned to Vinson & Elkins.

On Oct. 10, Regency and PVR announced their boards had approved a definitive merger agreement to enable Regency to acquire PRV. The acquisition is a unit-for-unit transaction that includes payments totaling about $40 million in cash. The $5.6 billion includes assumed debt of $1.8 billion.

The acquisition is expected to close during the first quarter of 2014, subject to approval of PVR unit-holders, along with Hart-Scott-Rodino Antitrust Improvements Act approval and customary closing conditions.

The Baker Botts lawyers representing Regency include partners Neel Lemon, Steve Marcus, Doug Rayburn and Luke Weedon, all of Dallas, Breen Haire, Joshua Davidson, Rob Fowler and Scott Janoe, all of Houston, and Paul Cuomo of Washington, D.C.; senior associate A.J. Ericksen of Houston and associate Daniel Gottschalk of Houston.

On the in-house side at Regency, assistant general counsel Frances Kilborne, assistant general counsel, is working on the acquisition, along with corporate counsel Jaclyn Thompson.

Bruce D. Davis Jr., PVR executive vice president and general counsel, led his company’s team.

Capital markets partners Michael Swidler and Mike Rosenwasser, both of New York City, led the V&E team, with assistance from John Johnston and Rachel Packer, also of New York. Others are partners Price Manford of New York, Gary Huffman of Washington, D.C. and David D’Alessandro of Dallas, and associates Ryan Carney and Robert Jacobson, both of Houston, and Melissa Spohn of Dallas.
