Thank you, operator, and good morning everyone. My name is Mac Jensen, and I serve as our company’s Senior Vice President of Business Development. Unfortunately, T. J. Thom is unable to join us today due to a family matter.

Joining me today is Gary Hanna, our Chairman, President and Chief Executive Officer. Also on the call and available to answer questions is Andre Broussard, Senior Vice President, Geosciences. We’ll begin today’s call with some opening comments from Gary, and then open it up for Q&A before turning the call back over to Gary for his closing remarks.

Before we begin with our prepared remarks, I’d like to bring your attention to certain disclaimers and other cautionary statements contained within our call today, as it pertains to forward-looking information and statements regarding EPL. Those forward-looking statements are contained in our most recent press release issued this morning and are also applicable to this conference call. After our prepared remarks, we’ll have some time to take some of your questions.

I’ll now turn the call over to Gary.


Gary Hanna

Chairman, President and CEO, EPL

Thanks, Mac, and good morning to everyone.

This morning we were very pleased to announce that EPL has entered into an agreement with Energy XXI in which Energy XXI will acquire EPL, creating the largest independent, publicly-traded, pure-play Gulf of Mexico shelf operator with a combined enterprise value of approximately $6 billion.

Strategically and financially, this is the right deal at the right time for shareholders of both companies.

The combined company’s size and scale will lead to a strong foundation for growth and financial flexibility. Our complementary acquire & exploit strategies will benefit from our respective historical focus on development of upside inventory, while the combined company’s critical mass and enhanced organizational strength will enable it to capitalize on shallow depth exploitation, secondary recovery and intermediate depth exploration across the high quality asset base. Looking to the future, large contiguous acreage positions, high working interests and operational control as found in the combined company will be keys to future exploitation and exploration success.

We expect the combined companies’ complementary skill set and asset portfolio will also result in significant synergies. Initial estimates show the potential for significant lease operating and overhead cost savings.

Above all, the deal represents an attractive premium for EPL shareholders. In addition to the 34% premium to our share price, our shareholders can continue to enjoy equity upside in what will be an exciting growth story in the Gulf of Mexico shelf.

The transaction has been approved by each company’s board of directors and is anticipated to close second quarter of 2014, subject to approval of EPL and Energy XXI shareholders, as well as customary regulatory approvals. We

anticipate a seamless integration process, as both companies are committed to a thoughtful integration process designed to capture value for our shareholders, with growth opportunities for our employees.

And with that we’ll be happy to take your questions. [Operator?]


Thank you to everybody for joining today’s call.

I would just like to conclude by reiterating how excited we are about the opportunities that the combination presents our many stakeholders.

Today’s combination represents a landmark moment for both companies as we have successfully identified and executed on a rare opportunity to combine a property portfolio of this asset quality, strategic fit and size.

Our team is available to answer any further questions you have throughout the day.
