Filed by Kinder Morgan, Inc.

Pursuant to Rule 425 Under the Securities Act of 1933

And Deemed Filed Pursuant to Rule 14a-12

Under the Securities Exchange Act of 1934

Subject Company:  El Paso Corporation

Commission File No.:  001-14365

Kinder Morgan, Inc. distributed the following six documents in connection with its proposed acquisition of El Paso Corporation:

We are delighted to announce that Kinder Morgan, Inc. has entered into an agreement to acquire El Paso Corporation.  As stated in the news release, we believe this transaction is a win-win opportunity for both companies, the employees and their shareholders.  We’re bullish on the future of natural gas use in the United States and combining Kinder Morgan and El Paso is a tremendous opportunity for all of us!  We are creating a larger company with great assets, which should equate to more opportunities and greater value for employees.

We want to thank you for making this transaction possible.  We were only able to make this acquisition because of your ongoing hard work and the successes that we have experienced together through the years in growing our company.

When the transaction is completed, likely in the second quarter of 2012, Kinder Morgan will be the largest midstream and the fourth largest energy company in North America with an enterprise value of approximately $94 billion and 80,000 miles of pipelines.  The combination of KMI and El Paso is expected to produce immediate value (upon closing) to KMI and KMR shareholders and to KMP and El Paso Pipeline Partners unitholders through strong cash flow accretion, and offers significant future growth opportunities.

Through this transaction we will have an opportunity to continue to build an even greater company, as expanding our footprint of natural gas assets should lead to additional growth opportunities related to the natural gas shale plays and the expected increase in demand for natural gas as the fuel of choice in the United States.  This combined company will have a natural gas pipeline transportation network of approximately 67,000 miles.  The natural gas pipeline systems of the two companies are very complementary, as they primarily serve different supply sources and markets in the United States.

The combined company will be named Kinder Morgan, Inc. and corporate headquarters will remain in Houston.  I’m sure some of you are wondering how this transaction will

change your daily responsibilities.  For most of you, we don’t believe there will be any change.  Obviously there is a substantial integration process to be completed in the coming months before the transaction closes.

If all goes as expected, KMI and El Paso will be one company soon.  Until then, it’s important for all of us to do everything we can to stay focused on performing our jobs to the best of our abilities to positively position each company for the future.  At Kinder Morgan, we should remain focused on striving for financial and operational excellence, and meeting our customers’ needs.

Rich Kinder

Let me begin by telling you how delighted we are to enter into an agreement to combine Kinder Morgan, Inc. with El Paso Corporation.  As stated in the news release, I believe this transaction is a win-win opportunity for both companies, the employees and their shareholders.  I’m bullish on the future of natural gas use in the United States and combining Kinder Morgan and El Paso is a tremendous opportunity for all of us!  We are creating a large company with great assets, which should equate to more opportunities and great value for employees.

El Paso Corporation shareholders have been offered a substantial per-share premium through this transaction.  The combination of KMI and El Paso is also expected to produce immediate value (upon closing) to KMI and Kinder Morgan Management shareholders and to Kinder Morgan Energy Partners and El Paso Pipeline Partners unitholders through strong cash flow accretion, and offers significant future growth opportunities.

When this transaction is completed, which will likely occur in the second quarter of 2012, you will be part of the largest midstream and the fourth largest energy company in North America with an enterprise value of approximately $94 billion and 80,000 miles of pipelines.  We have an opportunity to build a great company together, as combining our gas assets should lead to extraordinary growth opportunities related to the natural gas shale plays and the expected increase in demand for natural gas as the fuel of choice in the United States.  The combined company will feature:

·                  Largest owner and operator of natural gas pipelines and storage assets in North America with approximately 67,000 miles of natural gas transportation pipelines.  Pipelines are connected to many important natural gas shale pays including Eagle Ford, Marcellus, Utica, Haynesville, Fayetteville and Barnett.  Largest provider of contracted natural gas treating services and significant other midstream gathering assets.

·                  Largest independent transporter of petroleum products in the United States.  Transport approximately 1.9 million barrels per day of gasoline, jet fuel, diesel, natural gas liquids and crude oil through more than 8,000 miles of pipelines.

·                  Largest transporter of CO2 in the United States.  Transports 1.3 billion cubic feet per day.  Carbon dioxide is used in enhanced oil recovery projects.

·                  Second largest oil producer in Texas, producing more than 50,000 barrels per day.

·                  Largest independent terminal owner/operator in the U.S.  Liquids terminals have capacity of 107 million barrels and store refined petroleum products, ethanol and more.  Dry bulk terminals are expected to handle over 100 million tons of materials in 2011, including products like coal.

5

·                  Only oilsands pipeline serving the West Coast.  The Trans Mountain pipeline system transports 300,000 barrels of crude oil per day to Vancouver, B.C., and Washington state.

I know that you have many questions and we’ll do our best to answer them and keep you informed as the integration process progresses.  Here are some of the basics:

·                  The combined company will be named Kinder Morgan, Inc. and corporate headquarters will remain in Houston.

·                  While it will become part of the Kinder Morgan family of companies upon closing, El Paso Pipeline Partners will continue to operate under its current name as an entity listed on the New York Stock Exchange.

·                  We will stick to Kinder Morgan’s core businesses and plan to sell El Paso Exploration & Production Company.

If all goes as expected, Kinder Morgan and El Paso will be one company soon.  Until then, it’s important for all of us to do everything we can to stay focused on performing our jobs to the best of our abilities to positively position each company for the future.  At Kinder Morgan, we strive for both financial and operational excellence and to meet our customers’ needs, and I know you have similar goals at El Paso.

If you’re interested in knowing more about Kinder Morgan, which is primarily a pipeline transportation and terminal company, I encourage you to visit our web site at www.kindermorgan.com.

Thanks, and we look forward to welcoming you to the Kinder Morgan family when this transaction closes!

Kinder Morgan/El Paso Employee Q&A

Q             Why is El Paso Corporation selling?

A             El Paso Corporation shareholders have been offered a substantial per-share premium through this transaction.  By combining with Kinder Morgan — a company with a successful track record of growing and delivering attractive returns to shareholders — El Paso will be in a better position to pursue growth opportunities by becoming part of a larger company with additional financial clout and resources.  The combination also provides a good strategic fit of similar assets with relatively little overlap of operations.  As a result, the combined entity will have geographic reach that neither company enjoyed on its own.

Q             What are the benefits of the Kinder Morgan-El Paso merger?

A             This merger will create the largest midstream and the fourth largest energy company in North America with an enterprise value of approximately $94 billion and 80,000 miles of pipelines.  Upon closing, likely in the second quarter of 2012, the transaction is expected to produce immediate value to KMI shareholders, KMP and El Paso Pipeline Partners unitholders, and KMR shareholders through strong cash flow accretion.  Expanding our footprint of natural gas asset should lead to additional growth opportunities related to the natural gas shale plays and the expected increase in demand for natural gas as the fuel of choice in the United States.

Q             Who must approve the transaction?

A             We will need Hart-Scott-Rodino anti-trust approval, and shareholders at both KMI and El Paso Corporation must approve the transaction.

Q             When will the shareholder votes take place?

A             By January 2012.

Q             What will be the name of the company?

A             The El Paso corporate name will be replaced by Kinder Morgan, Inc. and the company will trade on the New York Stock Exchange under the ticker symbol KMI.  The other Kinder Morgan publicly traded entities will be:  Kinder Morgan Energy Partners, L.P. (NYSE: KMP), Kinder Morgan Management, LLC (NYSE: KMR) and El Paso Pipeline Partners, L.P. (NYSE: EPB).

Q             What is Kinder Morgan’s overall strategy?

A             Kinder Morgan’s strategy is very simple and has remained consistent since 1997: 1) we own and operate primarily fee-based assets that are core to the North American energy infrastructure that produce stable and substantial cash flow; 2) we run these assets as safely and efficiently as possible with a strong commitment to protecting the public, our employees, contractors and the environment; 3) we control costs as it’s the investors’ money — not management’s; 4) we leverage our

15

asset footprint to seek attractive capital investment opportunities through both expansions and acquisitions; and, 5) we maintain a strong balance sheet which enables us to access the capital markets to continue growing the business.  Additionally Kinder Morgan tries to align management’s interests with shareholders.  For example, Chairman and CEO Richard Kinder currently owns about 31 percent of KMI and receives a salary of $1 a year, no bonuses, no stock option grants and no restricted stock.

Q                                       How does Kinder Morgan expect to achieve efficiencies?

A                                      Kinder Morgan has been very successful in acquiring and merging companies and operating assets efficiently.  At Kinder Morgan, the philosophy is to reduce corporate overhead expenses and apply a disciplined budgeting approach to operations.  For example, the company caps base salaries for executives, and eliminates corporate perks and other unnecessary overhead.  It has no corporate aircraft, no sponsorships, no sports tickets, no club memberships, and no supplemental retirement or special benefit plans for senior executives.  We often say that Kinder Morgan is a company run by shareholders for shareholders.  In short, management tries to run the company like a prudent person would run his or her own personal affairs and spend money on the things that really matter, like maintaining our assets.  The hands-on senior management team meets weekly with Kinder Morgan business unit presidents and operational heads to review financial performance and receive operational updates.

Q                                       Can you expand more on Kinder Morgan’s track record?

A                                      Kinder Morgan is committed to delivering attractive returns to its shareholders.  Almost all of Kinder Morgan’s assets exist at KMP, which has produced a compound annual growth rate to unitholders of 25 percent since 1996.  KMR’s annual return to shareholders has been 14 percent since 2001 and KMI just went public again earlier this year.

Q                                       Will El Paso have any members on the Kinder Morgan board of directors?

A                                      El Paso will have two members on the KMI board of directors who will be identified by the El Paso Corporation board.

Q                                       Will KMI sell any El Paso Corporation assets to KMP or El Paso Pipeline Partners?

A                                      Yes.  Over the next few years we plan to sell some of the pipelines from El Paso Corporation to KMP and some to El Paso Pipeline Partners.  Again, the MLP structure is the most advantageous entity to own these types of assets.  This will make the transaction more accretive as time goes on.

Q                                       Will El Paso Pipeline Partners keep that name?

A                                      While it will become part of the Kinder Morgan family of companies when the transaction closes, El Paso Pipeline Partners will continue to operate under its current name as an entity listed on the New York Stock Exchange.  It is possible

16

that it will be combined with KMP in the future, but that is not part of this transaction.

Q                                       Do you anticipate layoffs?  When will they occur and how many?

A                                      Combined, the companies currently have approximately 12,800 employees.  We will be assessing the future organizational structure of the new company.  We are looking for synergies and there will be some workforce duplication that will lead to reductions.  For example, there will be a number of duplicative corporate functions.  Any reductions would not occur prior to closing.  However, we intend to communicate any reductions as soon as possible following our assessment, and this generally occurs in advance of the closing.

Q                                       Will reductions come from both companies?

A                                      Again, we are assessing the organizational structure.  The company’s underlying principle is to keep the best people and those employees who agree with Kinder Morgan’s business philosophy, so that they will fit into its culture.

Q                                       What will happen to El Paso Exploration & Production Company employees?

A                                      Exploration and production is not core to our business at Kinder Morgan and we plan to sell this company.  Our understanding is that the E&P company currently has 700 employees and El Paso has identified 400 shared service employees that were to be assigned to that company at the time of the projected spin off.  As a result, approximately 1,100 El Paso Corporation employees will be part of the exploration and production company and it will be up to the new owners to make any final decision on that workforce.

Q                                       Will there be severance for employees whose positions are eliminated?

A                                      Yes, Kinder Morgan will honor the existing El Paso severance plan for a certain period of time following the merger.  However, to be eligible for severance: 1) the transaction must close; and, 2) the employee must meet the terms of the plan that they are covered under.

Q                                       Will employees be offered enhanced early retirement opportunities?

A                                      It is premature to discuss this until we are further along in the evaluation and integration process.

Q                                       Will benefits change for El Paso employees?

A                                      Our long-term goal is for all employees to be under one set of benefits.

Q                                       Where will the corporate headquarters of the combined company be?

A                                      Houston, Texas.

Q                                       Will the main headquarters be in One Allen Center (Kinder Morgan’s current location at the intersection of Smith and Dallas) or in the El Paso building on Louisiana?

17

A                                      We are currently evaluating that and a decision will be made in the future.

Q                                       Will some employees have to relocate?

A                                      Again, that will be determined through the evaluation and integration process.  However, it is likely that the majority of employees, especially the field and Houston-based employees, will not require a geographic move.

Q                                       How many senior executives from El Paso will be retained?

A                                      That is still to be determined, but Kinder Morgan’s Office of the Chairman will remain the same.  Richard D. Kinder is Chairman and CEO, C. Park Shaper is President and Steven J. Kean is Chief Operating Officer.

Q                                       Is this a merger or an acquisition?

A                                      Kinder Morgan is acquiring El Paso.  However, the boards of directors of both companies approved the transaction.

Q                                       Does Kinder Morgan expect other companies will bid on El Paso Corporation?

A                                      Other companies could bid on El Paso, but KMI will receive a breakup fee if the transaction does not go through.

Q                                       How much is the breakup fee?

A                                      There is a breakup fee of approximately $650 million.

Q                                       How will this deal impact the community organizations El Paso Corporation supports?

A                                      Kinder Morgan supports the communities it serves through the Kinder Morgan Foundation, and we expect the combined entity will continue with that approach.
