(n/k/a Portcullis Holdings, Inc.) ("Portcullis Holdings") and William V. Morgan ("Mr. Morgan" and together with Portcullis Holdings, the "Reporting Persons") on October 8, 1999 (re-filed on November 16, 1999), as amended by Amendment No. 1 thereto on November 8, 1999 (re-filed on November 16, 1999) (the "Schedule 13D") relating to the shares of common stock, par value, $5.00 per share, of Kinder Morgan, Inc. (the "KMI Common Stock"). The principal terms used but not defined herein shall have the meanings ascribed to them in the Schedule 13D. Except as specifically provided herein, this Amendment No. 2 does not modify any of the information previously reported on the Schedule 13D. This Amendment No. 2 speaks as of its date and no inference should be drawn that no change has occurred in the facts set forth herein after the date hereof. After the filing date of Amendment No. 1 to the Schedule 13D, Portcullis Holdings ceased to own more than 5% of the outstanding KMI Common Stock. After such time, all of the KMI Common Stock of Portcullis Holdings was transferred to Portcullis Partners, LP, a partnership indirectly controlled by Mr. Morgan ("Portcullis Partners"). Mr. Morgan and Portcullis Partners intend to participate with a group of other investors in a proposal to acquire all of the outstanding KMI Common Stock. Certain persons participating in such proposal, including Mr. Morgan and Portcullis Partners, filed a statement on Schedule 13D on May 30, 2006 with respect to the KMI Common Stock as a group (the "Group Schedule 13D"). The Schedule 13D shall be considered amended and supplemented by the Group Schedule 13D and any and all amendments thereto, and no additional amendments to the Schedule 13D will be made unless or until the Group Schedule 13D is no longer applicable. Readers are directed to the Group Schedule 13D and any and all amendments thereto for future information regarding Mr. Morgan or Portcullis Partners with respect to the KMI Common Stock. ITEM 1. SECURITY AND ISSUER No change. ITEM 2. IDENTITY AND BACKGROUND. (b) The address of the principal business office of Portcullis Holdings and the address of Mr. Morgan is 5 Post Oak Park, 4400 Post Oak Parkway, Suite 1450, Houston, Texas 77027. ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION. No change. Page 4 of 6 ITEM 4. PURPOSE OF TRANSACTION. The Governance Agreement has expired and the Group Schedule 13D has been filed, so Item 4 is amended and restated to read as follows: (a)-(j) Mr. Morgan and Portcullis Partners intend to participate with a group of other investors in a proposal to acquire all of the outstanding KMI Common Stock. Certain persons participating in such proposal, including Mr. Morgan and Portcullis Partners, filed the Group Schedule 13D, which provides additional information regarding the acquisition proposal. The Reporting Persons may make additional purchases of KMI Common Stock either in the open market or in private transactions. The Reporting Persons reserve the right to formulate specific plans or proposals with respect to, or to change their intentions regarding, any or all of the foregoing. ITEM 5. INTEREST IN SECURITIES OF THE ISSUER. No changes. ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER. The Governance Agreement has expired, so all references to the "Governance Agreement" in Item 6 are deleted. ITEM 7. MATERIAL TO BE FILED AS EXHIBITS. The Governance Agreement has expired, so all references to the "Governance Agreement" in Item 7 are deleted.
