     ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

     The shares of KMI Common Stock that each of Mr. Michael Morgan, Mr. Shaper,

beneficially own their shares of KMI Common Stock as successors to Morgan
Associates, Inc., which acquired its shares as set forth in the Morgan Schedule
13D.\

     With respect to the proposed transaction described in Item 4 of this

Persons estimate that the amount of funds necessary to consummate the
transaction would consist of the following: (i) approximately $2.8 billion in
equity (based on the proposed Offer Price (as defined in Item 4)) being
rolled-over in the acquisition by the Reporting Persons and certain other
specified persons; (ii) approximately $4.5 billion of new equity financing that
would be provided by the Sponsors; and (iii) approximately $14.5 billion of debt
that would either remain outstanding or be incurred in connection with the
transaction as further described in Item 4 and the Proposal Letter and the Debt
Financing Letter (each as defined in Item 4).

     The information set forth in response to this Item 3 is qualified in its
entirety by reference to the Proposal Letter and the Debt Financing Letter,
which are incorporated herein by reference.

     The information set forth in this Item 3 shall be deemed to supplement Item
3 of each of the Kinder Schedule 13D and the Morgan Schedule 13D.

     ITEM 4. PURPOSE OF TRANSACTION.

     As set forth in a letter dated May 28, 2006 (the "Proposal Letter"), Mr.
Richard Kinder and the Sponsors have submitted to the Issuer's Board of
Directors (the "Board of Directors") a proposal to acquire all of the
outstanding KMI Common Stock (the "Proposal"), except for certain shares of KMI
Common Stock held by the Reporting Persons and certain other specified persons
expected to be rolled-over in the acquisition. Each of the Reporting Persons
intend to participate in the Proposal. A copy of the Proposal Letter is being
filed herewith as Exhibit 7.02.

     The Proposal contemplates that the transaction would be effected through a
merger of a new acquisition corporation to be formed by the Reporting Persons
and the Sponsors ("Acquisition Corp.") with and into the Issuer. Mr. Richard
Kinder intends to roll-over all of his KMI Common Stock in the acquisition. The
other Reporting Persons (except for Portcullis Partners and Mr. Michael Morgan)
intend to roll-over all or a substantial portion of their KMI Common Stock in
the acquisition. Portcullis Partners and Mr. Michael Morgan intend to
collectively roll-over 600,000 shares of KMI Common Stock. The KMI Common Stock
of the Reporting Persons and certain other specified persons that would be
rolled-over in the acquisition would be contributed to a parent entity of
Acquisition Corp. immediately prior to the merger in exchange for equity
interests in such parent entity. All of the other KMI Common Stock (including
the shares of KMI Common Stock held by the Reporting Persons and not contributed
to the parent entity of Acquisition Corp. as described above) would be converted
into the right to receive a cash payment equal to $100 per share (the "Offer
Price"). If such merger is consummated, the KMI Common Stock will no longer be
traded on the New York Stock Exchange and the registration of the KMI Common
Stock under Section 12 of the Securities Exchange Act of 1934, as amended, will
be terminated. The Board of Directors has formed a special committee of
independent directors (the "Special Committee") to consider the terms of the
Proposal and to recommend to the Board of Directors whether to approve the
Proposal.

                                 Page 15 of 21

Stock will no longer be traded on the New York Stock Exchange and the
registration of the KMI Common Stock under Section 12 of the Securities Exchange
Act of 1934, as amended, will be terminated. The Board of Directors has formed a
special committee of independent directors (the "Special Committee") to consider
the terms of the Proposal and to recommend to the Board of Directors whether to
approve the Proposal.

     On May 29, 2006, a press release related to the Proposal was issued by Mr.
Richard Kinder and the Sponsors. A copy of the press release is being filed
herewith as Exhibit 7.03.

     To finance the Proposal, Mr. Richard Kinder and the Sponsors have received
a letter from Goldman Sachs Credit Partners L.P., stating that Goldman Sachs
Credit Partners L.P. is "highly confident" that it can obtain the required debt
financing (the "Debt Financing Letter"). A copy of the Debt Financing Letter was
furnished to the Board of Directors in connection with the Proposal and is being
filed herewith as Exhibit 7.04. In addition, approximately $4.5 billion of
equity financing would be provided by the Sponsors. The Reporting Persons expect
that executed debt and equity commitment letters will be delivered from their
financing sources prior to the execution of definitive agreements related to the
proposed merger.

     Except as otherwise provided herein, with respect to the Proposal or any
matters related thereto, the Reporting Persons' intent is to be purchasers of
shares of KMI Common Stock of the Issuer not already owned by them and not
sellers of shares of KMI Common Stock owned by them.

     The foregoing is a summary of the Proposal and should not be construed as
an offer to purchase shares of KMI Common Stock. A proxy statement will be
distributed to stockholders of the Issuer if and when definitive documentation
is entered into by the Issuer and all other appropriate parties. Stockholders
should read the Issuer's proxy statement and other relevant documents regarding
the Proposal filed with the SEC when they become available because they will
contain important information relevant to the decision to approve the proposed
merger. Stockholders will be able to receive these documents (when they become
available), as well as other documents filed by the Reporting Persons or their
respective affiliates with respect to the Proposal and the proposed merger, free
of charge at the SEC's web site, www.sec.gov.

     Other than as set forth herein or in the Proposal Letter and the Debt
Financing Letter, the Reporting Persons have no plans or proposals that relate
to or would result in any of the events set forth in Items 4(a) through (j) of
Schedule 13D. However, if the Proposal is not consummated for any reason, the
Reporting Persons intend to review continuously the Issuer's business affairs,
capital needs and general industry and economic conditions, and, based on such
review, the Reporting Persons may, from time to time, determine to increase
their respective ownership of KMI Common Stock, approve an extraordinary
corporate transaction with regard to the Issuer or engage in any of the events
set forth in Items 4(a) through (j) of Schedule 13D, but, except as otherwise
provided herein, the Reporting Persons currently have no intention of selling
any shares of KMI Common Stock.

     No guarantees can be given that the proposed merger will be consummated. No
binding obligation on the part of the Issuer or any of the Reporting Persons or


                                 Page 16 of 21


the Sponsors shall arise with respect to the proposed merger unless and until
mutually acceptable definitive documentation has been executed and delivered.

     The information set forth in response to this Item 4 is qualified in its
entirety by reference to the Proposal Letter and the Debt Financing Letter,
which are incorporated herein by reference.

     The information set forth in this Item 4 shall be deemed to supplement Item
4 of each of the Kinder Schedule 13D and the Morgan Schedule 13D.
