EP Energy to be Acquired by Apollo Global Management, LLC; Riverstone Holdings, LLC; and Access Industries

Dear EP Energy Team:

At our town hall earlier this year and in group gatherings, I’ve told you that I expected our future would become clearer in the first quarter. Today, after a lot of work on the part of everyone on this team, we have real clarity on and exciting news about our future. In a news release that was just issued, El Paso Corporation announced that it had entered into a definitive agreement to sell our exploration and production business, EP Energy, for approximately $7.15 billion to affiliates of Apollo Global Management, LLC and Riverstone Holdings, LLC, who are joined by Access Industries, Inc. and other parties. Let me take a few minutes to tell you about the transaction, what it means for you, and what’s next.

About the Transaction

As detailed in the announcement, the sale is dependent upon completion of the Kinder Morgan-El Paso transaction, which is still expected to close in the second quarter of 2012, subject to customary regulatory approvals. The sale of EP Energy is also expected to close about the same time as that transaction. Going forward, our company will be private, will be named EP Energy, and our investors have asked the current EP Energy leadership team to remain with the company.

With that overview of the transaction in mind, let me tell you a little more about our investors.

·                  Apollo Global Management, LLC is a leading global alternative investment manager that invests in private equity, credit-oriented capital markets, and real estate. They are headquartered in New York City with offices around the world, including Houston. With more than 21 years experience in their business, Apollo has assets under management of more than $75 billion in private equity, credit-oriented capital markets and real estate funds invested across a core group of nine industries. Its portfolio included energy-related investments in Parallel Petroleum and Athlon Energy. Apollo is traded on the NYSE under the symbol APO, and you can review their website at www.agm.com.

·                  Riverstone Holdings LLC, an energy and power-focused private equity firm founded in 2000, has more than $18 billion of equity capital raised across seven investment funds and co-investments, including the world’s largest renewable energy fund. Riverstone conducts buyout and growth capital investments in the midstream, exploration and production, oilfield services, power and renewable sectors of the energy industry. It has offices in New York, London, and Houston, and had about $16.4 billion of investments in North America, Latin America, Europe and Asia. Riverstone is a private company, and you can review their website at www.riverstonellc.com.

·                  Access Industries is a privately held, U.S.-based industrial group with long-term holdings worldwide. Access’ focus spans three key sectors: natural resources and chemicals; telecommunications and media; and real estate. You can review their website at www.accessindustries.com.

What it Means for You

I know you have questions about what this transaction means to you, what programs and services will be offered, and other employee-related matters. It’s very early in the process, and I don’t have definitive answers to those questions yet. However, I can tell you that Apollo, Riverstone, and Access value the caliber of our team and the commitment, knowledge, and experience that we bring to the table. I’m confident they’ll work closely with us to ensure this is a company you want to continue working for and that we do what’s right for the company and for employees. As we get answers to your questions, we’ll update you.

We’ll start that process with a town hall in Houston at 2 p.m. on Monday, February 27. At the meeting, we’ll discuss the transaction and answer your questions. You’ll receive an invitation to the meeting shortly with location information and call in numbers. Please plan to join us. We’re also creating a special section on El Paso Today that will capture all the communications about the proposed transaction and the integration process, including a preliminary set of questions and answers. In addition, I’ll continue to host regular floor meetings, Q&A sessions, and town halls over the next few months to update you on our progress and answer your questions. The senior leadership team will host similar meetings for their functional areas. Finally, please remember that you can always talk to your supervisor and/or HR representative.

What’s Next

In the meantime, we’re already working on the transition process. The good news is that the work we did on our spinoff, Project Zygosity, and the pre-planning we’ve done over the past few months in association with the sale have put us in a great position to continue into the next phase of our story. As we move into that phase, I’m going to ask you to reflect on the news, stay focused, and continue to perform to your high standards. We’ll all need to balance the requirements of a transition and integration process on a tight timeframe and with the need to maintain our ongoing business. Over the past year, I’ve seen us rise to the occasion time and time again. I’m confident that, working together, we can do it again.

This is a great outcome, one that gives our investors a strong position in the E&P business; delivers value for shareholders on all sides of the transaction; and, most importantly, keeps one of the strongest teams in the industry working together toward a common goal. Together, we’ve been working hard to finish our story strong, with pride. Now, we need to continue to deliver through the closing of the sale and beyond. With today’s news, we can pick up where we left off on the EPE path and start a new chapter together.

We will speak again soon and often. Until then, stay focused, be safe and continue to do all you do to deliver high-end performance across our organization.

Regards,

Brent

EP Energy to be Acquired by Apollo Global Management, LLC; Riverstone Holdings, LLC; and Access Industries

Dear Team El Paso:

I have important news to share with you. As you may have already heard, in a news release issued earlier today, El Paso Corporation announced that it had entered into a definitive agreement to sell our exploration and production business, EP Energy, for approximately $7.15 billion to affiliates of Apollo Global Management, LLC and Riverstone Holdings, LLC, who are joined by Access Industries, Inc. and other parties. This is exciting news, and I’d like to take a minute to tell you why. Let me start with some details about the transaction.

About the Transaction

As detailed in the news release, the sale is dependent upon completion of the Kinder Morgan-El Paso transaction, which is expected to close in the second quarter of 2012, subject to customary regulatory approvals. The sale of EP Energy is also expected to close about the same time as that transaction. Going forward, the company will be private and will be named EP Energy. Importantly, the investors have asked the current EP Energy leadership team to remain with the company.

With that overview of the transaction in mind, let me tell you a little more about the investors.

·                  Apollo Global Management, LLC is a leading global alternative investment manager that invests in private equity, credit-oriented capital markets, and real estate. They are headquartered in New York City and have offices around the world, including in Houston. Apollo has assets under management of more than $75 billion in private equity, credit-oriented capital markets and real estate funds invested across a core group of nine industries. They are traded on the NYSE under the symbol APO, and you can learn more about them at www.agm.com.

·                  Riverstone Holdings LLC, an energy and power-focused private equity firm founded in 2000, has more than $18 billion under management across six investment funds, including the world’s largest renewable energy fund. Riverstone conducts buyout and growth capital investments in the midstream, exploration and production, oilfield services, power and renewable sectors of the energy industry. It is a private company, and you can review their website at www.riverstonellc.com.

·                  Access Industries is a privately held, U.S.-based industrial group with long-term holdings worldwide. Access’ focus spans three key sectors: natural resources and chemicals; telecommunications and media; and real estate. You can review their website at www.accessindustries.com.

What it Means to Us

With those details in mind, let’s talk for a minute about what this sale means to our EP Energy colleagues, to the rest of Team El Paso, and to our shareholders.

First, for those members of the team who were designated as EP Energy employees, this sale represents a unique opportunity. Over the past few years, they’ve built a high-performing E&P company that’s truly an industry leader. Going forward, they’ll have the chance to continue to build on their success. And they’ll have the commitment of investors with strong financial resources and a keen interest in their success. Between now and closing they will be heads down on transition work, much of which was contemplated as part of Project Zygosity last year. I know I can count on everyone on Team El Paso to support them in that effort.

For the rest Team El Paso, the announcement of this sale is another important milestone along the path toward creating the largest natural gas pipeline enterprise, the largest midstream energy company, and the fourth largest energy corporation in North America. By now, we’ve all had a chance to better understand Kinder Morgan’s approach to their business. We worked closely with them on the sale of our E&P assets, a process that received a lot of interest. The success of that process is further evidence that Kinder Morgan, like us, is fully committed to completing our transaction.

Finally, this sale helps clear the way for us to continue on the path we’ve been following with our shareholders. It should provide greater clarity as we move forward with the transaction and the integration process. In short, it will help us better focus on executing on our plan, delivering on our financial and operational results, and seizing opportunities to grow as part of a larger platform.

When I initially spoke about the Kinder Morgan transaction and the sale of our E&P assets, I told you that I believed the E&P sale would position EP Energy for future success and growth as a pure play with the right strategies, the right inventory, and the right people. Now, with the right investors added to that equation, I’m more confident than ever about the EP Energy’s potential for continued success in the years ahead.

Please join me in congratulating the EP Energy team on this announcement and in supporting them as they prepare to enter the next phase of their growth and success. And until we talk again, be safe, work hard, and keep doing the right thing for the owners who have entrusted their investments to our care.

Talk to you soon.

Doug

medical coverage. As always, we will continue to evaluate our programs going forward to ensure they’re competitive in the market.

24.       What will happen to my compensation and benefits?

·                  At this time, we don’t expect wholesale changes to the compensation or benefits plans that were planned for EP Energy as part of the separation. Because we will be a privately held entity without a publicly traded equity, we’ll need to design a new long-term incentive program. We will provide details about this program as soon as possible. As always, we’ll continue to evaluate our programs going forward to ensure they’re competitive in the market.

25.       Will we have a pension?

·                  No. Similar to what we planned during Project Zygosity, EPE will not be offering a pension plan. We intend to make additional company contributions to the 401(k) plan. We will share more details about these plans as soon as possible.

26.       What sort of cash bonus programs will be offered?

·                  We anticipate our bonus program will be similar to the one we currently have in place for the E&P company. We have agreed with our investors that our bonus pool will be funded at a minimum of 100 percent of target for 2012 performance which will be paid in 2013.

27.       What will happen to my restricted stock and options?

·                  The sale of the E&P Company does not impact the anticipated vesting of your unvested equity and options at the close of the merger of El Paso with Kinder Morgan.

28.       How will this announcement affect our retention bonus program?

·                  For Tier I participants in the retention bonus program, the sale is considered a triggering event since more than 85 percent of the EP Energy assets have been sold. This means payment will be made to eligible Tier I participants as soon as administratively practicable after the close of the transaction.

5

·                  Payments of the Tier II awards will be made to eligible Tier II participants on the first anniversary of the closing date of the KMI/EP merger, based on the final gross sale proceeds.

29.       Will we continue with our community giving and volunteerism following the close of the transaction?

·                  We don’t have any information on the investors’ programs in these areas following the completion of the transaction, but we will follow up with employees when we have information to share.

30.       What should I say if I am contacted by the media?

·                  The sale may result in attention from the media and it is important that we speak with one voice.  Please refer all calls to Investor & Media Relations:

Leader Talking Points

Communications Tips:  With the announcement today that Apollo Global Management, Riverstone Holdings, and Access Industries are acquiring El Paso’s E&P company, it’s important that you connect with and engage your teams as soon as possible. Remember, they may or may not have heard about the announcement or seen Brent’s communication to EP Energy employees. Please call or contact each of your employees, and use the opportunity to ensure they are informed about the transaction, fully understand the context for the sale, and are engaged with the upcoming transition process.

Important note: Because we’re still operating under a one Team El Paso approach and, as such, our current organizational structures and reporting relationships do not yet reflect the adjustments that will be made following the proposed transactions, there are instances where team members may be reporting to an EPC leader today, but will report to an EPE leader after the transactions close.  In these cases, the EPC and EPE leaders should connect as soon as possible to discuss the best approach for contacting team members who have been designated for EPE.

This process will help ensure we’re all aligned and equipped with the information we need to continue our story strong, with pride.

·                  Hi and [good afternoon/good morning]…

·                  I wanted to reach out to you today/gather everyone together to discuss the announcement El Paso Corporation made about the sale of our E&P company, give you a brief overview of what’s happening, and talk about our path forward.

Inform Employees

·                  Earlier today/yesterday, El Paso Corporation announced that it has entered into a definitive agreement to sell El Paso Exploration and Production Company for approximately $7.15 billion to affiliates of Apollo Global Management, LLC and Riverstone Holdings, LLC, who are joined by Access Industries, Inc. and other parties. Let me give you some details about the investors:

·                  Apollo Global Management, LLC is a leading global alternative investment manager that invests in private equity, credit-oriented capital markets, and real estate. Headquartered in New York City and with offices around the world, including Houston, Apollo has assets under management of more than $75 billion in private equity, credit-oriented capital markets and real estate funds invested across a core group of nine industries.

·                  Riverstone Holdings LLC, an energy and power-focused private equity firm founded in 2000, has approximately $18 billion under management across six investment funds, including the world’s largest renewable energy fund. Riverstone conducts buyout and growth capital investments in the midstream, exploration and production, oilfield services, power and renewable sectors of the energy industry.

·                  Access Industries is a privately held, U.S.-based industrial group with long-term holdings worldwide. Access’ focus spans three key sectors: natural resources and chemicals; telecommunications and media; and real estate.

1

·                  Importantly, the investors are acquiring not just our assets and our team, but our plan and our strategy as well.

·                  Members of the team who were designated to be a part of EP Energy will be included in the sale.

·                  I want to thank everyone for all their efforts over the past few months to prepare for the asset package sale process, while maintaining high end performance in our regular business.

·                  As you know, selling the entire company was our preferred outcome for this process. We’re excited about keeping the team together as we pick up where we left off on the EPE path and start a new chapter together.

·                  Following the completion of the sale, which is expected to occur concurrent with the Kinder Morgan transaction, we will be a privately held company named EP Energy and remain headquartered in the downtown Houston building.

Provide Context

·                  With those details about the transaction in mind, let me tell you why this is such an exciting development for the EP Energy team.

·                  Over the past several years, we’ve built a high-performing E&P company that’s truly an industry leader. Most recently, we’ve proved that through efforts across the company to finish our story strong, with pride.

·                  While this sale represents the end of one story—the story of El Paso’s Exploration and Production Company—we’re now poised to continue the story of EP Energy.

·                  We’ll have a unique opportunity to continue to build on the success of the past few years. To do that, we’ll focus on what’s made us successful: building repeatable programs and significant project inventory, sharpening our execution skills, and effectively matching our assets with our competencies.

·                  We’re still committed to being a leader in safe and responsible energy development. And we will continue working as a team to make the right decisions and to drive high-end performance across our operations.

·                  Most importantly, we’ll continue to play a critical role as a high energy and high-performing exploration and production team that finds and delivers the energy that fuels our economy and our future, while delivering value for our owners and ourselves.

·                  As we pursue those goals, we’ll have the commitment of investors with strong financial resources and a keen interest in our success.

·                  In return for that support, our investors will look to us for our expertise and experience in the industry and with our assets, programs, and strategy. And we’ll be expected to deliver high end performance consistently across our operations.

2

·                  In that sense, nothing’s changed. I know I can depend on you and the entire team to meet that commitment.

·                  Finally, this sale is an important milestone in the Kinder Morgan’s acquisition of El Paso Corporation for our shareholders and for others with a stake in the success of that transaction. I’m excited about moving forward as a team to position our company for future success and growth with committed owners and the right strategy, the right inventory, and the right people.

Engage the Team

·                  With that context in mind, let’s talk about what’s next. Between now and the close of the Kinder Morgan-El Paso transaction, we have a lot of work to do. The good news is that much of what we accomplished with Project Zygosity as we prepared for the separation last year not only provided value to the sale, but sets us up for success in the process ahead.

·                  Work will begin right away on the transition planning processes. As we get more details about these processes and who will be involved, we’ll update you. In the meantime, our first course of action is to review the plans and programs we set in place under Project Zygosity, modify them as needed, and work together to implement them. In many cases, we can continue work on these efforts that is already underway.

·                  As we move into the transition process as a result of the proposed sale, we’ll need to continue working closely with our EPC colleagues. Please recognize that this is a challenging and uncertain time for these employees as the transition planning process with Kinder Morgan continues. As you work together in the coming weeks on various aspects of the two transactions, it’s important to remember that we all wear the same Team El Paso hat until the transactions are completed.

·                  I want to remind you that until the transaction closes, Apollo, Riverstone, Access, El Paso, and Kinder Morgan remain separate companies. Outside the ordinary course of business, you shouldn’t interact or share information with Kinder Morgan or the E&P company investors unless specifically requested to do so by El Paso’s legal or integration planning teams.

·                  Our reputation for performance and our winning strategy were key reasons why Apollo and Riverstone made the decision to acquire our company. Let’s pull together, build on our reputation in the months ahead, put our best performance forward, and work toward continuing our story strong, with pride.

In Closing

·                  To learn more about the sale, I’d encourage you to…

·                  Read the communication from Brent that was emailed to all EP Energy employees.

·                  Read the news release that’s posted on El Paso Today in the Company to Own section.

·                  There will be a lot more information to come on the transaction…

·                  We’re holding an EP Energy Town Hall in Houston at 2 p.m., Monday, February 27. At the meeting, Brent will discuss the transaction and answer your questions.

·                  We’re creating a special section on El Paso Today that will capture all the communications about the transaction.

·                  And, as always, talk to your supervisor and/or HR representative.

·                  Thank you again and keep doing everything you do, day-in and day-out, to make us a high-performing, fully executing E&P company.
