              My preference in outside transaction-counsel are professionals that are up to speed not only on current rules and regulations impacting potential transactions as well as custom and practice and what’s customary in typical PSAs, stock or merger agreements. I’m also looking for counsel that is easy to work with and understands the business well enough to know when counsel on the other side is blowing smoke. Porter Hedges has all of this as well as any of the rapidly changing technologies that come along to facilitate negotiating and consummating a transaction.

              As someone with 40 years’ experience in the oil-and-gas sector with a specific focus on transactions, I can say that the folks I’ve worked with are some of the very best in this area. All of those who I’ve worked with at Porter Hedges have extensive oil-and-gas transaction experience with some of the partners at the top having track records that if not the best are very close to the top in experience relative to the broad spectrum of situations you might run into. They have been side by side with me on hundreds of transactions (buying and selling) and on multiple billion-plus transactions.
