                                 SCHEDULE 13D/A
                                 --------------


     EXPLANATORY NOTES: This Amendment No. 2 amends and supplements the
statement on Schedule 13D originally filed by Morgan Associates, Inc. (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13D is no longer applicable.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.

the undersigned, such person certifies that the information set forth in this
Schedule 13D/A with respect to such person is true, complete and correct.
