(1)  Box (a) is checked with respect to the relationship of the Reporting
     Person and the other New Investors described in Item 4. As a result of the
     proposal and related agreements described in Item 4, the Reporting Person
     may be deemed to be the beneficial owner of shares of the Issuer's Common
     Stock beneficially owned by the New Investors described in Item 4. Based on
     information provided to the Reporting Person or in Schedules 13D filed by
     the other New Investors, Appaloosa Management LP and its related entities
     beneficially own 52,000,000 shares, Harbinger Capital Partners Master Fund
     I, Ltd. and its related entities beneficially own 26,450,000 shares,
     Merrill Lynch, Pierce, Fenner & Smith Incorporated and its related entities
     beneficially own 1,475,701 shares, Pardus Special Opportunities Master Fund
     L.P. and its related entities beneficially own 26,400,000 shares and
     Goldman Sachs & Co. and its related entities beneficially own 20,219,188
     shares. The total percentage of the outstanding shares of Common Stock
     beneficially owned by all of the New Investors and their related entities
     is approximately 23.31%.

(2)  Box (b) is checked with respect to the relationship of the Reporting
     Person and the Additional Investors described in Item 4. As a result of the
     arrangements in the Additional Investor Agreement described in Item 4, the
     Reporting Person may be deemed a member of a "group" within the meaning of
     Section 13(d) of the Securities Exchange Act of 1934, as amended, with the
     Additional Investors under the Additional Investor Agreement. The Reporting
     Person, however, expressly disclaims membership in any group with the
     Additional Investors as a result of the Additional Investor Agreement.



Item 1. Security and Issuer

This Amendment No. 1 (this "Amendment") to the Schedule 13D (the "Initial
Schedule 13D") initially filed on December 18, 2006 by the Reporting Person
relates to the common stock, $0.01 par value per share (the "Common Stock"), of
Delphi Corporation, a Delaware corporation (the "Issuer"), and is being filed to
amend the Initial Schedule 13D as specifically set forth below.

Certain information contained in this Schedule 13D/A relates to share ownership
of persons other than the Reporting Person. The Reporting Person expressly
disclaims any liability for any such information and for any other information
provided in this Amendment that does not expressly pertain to the Reporting
Person.

The information set forth in the Exhibits to this Amendment is hereby expressly
incorporated herein by reference, and the responses to each item of this
Amendment are qualified in their entirety by the provisions of such Exhibits.
Unless otherwise indicated, all capitalized terms shall have the meanings
ascribed to them in the Initial Schedule 13D, and unless otherwise amended
hereby, all information previously filed remains in effect.

Item 4 is hereby amended by adding the following:

Termination of Prior Agreements

On July 7, 2007, the Issuer delivered to the Reporting Person and the other
Investors certain notices of termination of the Investment Agreement and the
Plan Framework Support Agreement. Certain of the Investors continued to engage
in discussions with the Issuer regarding a possible restructured investment in
the Issuer in connection with the Issuer's reorganization, including many
elements similar to those contained in the Investment Agreement and the Plan
Framework Support Agreement.

New Proposal Letter

On July 17, 2007, ADAH, UBS Securities LLC, Del-Auto, Merrill, Goldman Sachs &
Co. ("GS") and Pardus DPH Holding LLC ("Pardus DPH") (an affiliate of Pardus
Special Opportunities Master Fund L.P. ("Pardus")) delivered to the Issuer a
proposal, which the Issuer accepted (subject to bankruptcy court approval), for
a potential investment of up to $2.55 billion in the aggregate in preferred and
common equity of the reorganized Issuer and a proposed reorganization framework
for the Issuer (the "New Proposal"). Each of ADAH, UBS Securities LLC, Del-Auto,
Merrill, GS and Pardus DPH are referred to herein as the "New Investors." Each
of UBS Securities LLC, Del-Auto, Merrill, GS and Pardus DPH are referred to
herein as the "Co-Investors." A copy of the New Proposal is attached hereto as
Exhibit I.

According to the New Proposal, the New Investors would enter into an Equity
Purchase and Commitment Agreement (the "New Investment Agreement") providing for
the potential equity investment. The New Proposal will terminate if, on or
before August 16, 2007, (x) the United States Bankruptcy Court for the Southern
District of New York (the "Bankruptcy Court") does not issue an order reasonably
satisfactory to the New Investors approving and authorizing the Issuer to enter
into the New Investment Agreement and certain other matters, (y) the Issuer has
not entered into the New Investment Agreement or (z) any of the New Investors
determines in its sole discretion that any of the conditions contained in the
New Investment Agreement are incapable of being satisfied or that any of the New
Investors is entitled to exercise a termination right under the New Investment
Agreement.

Equity Investment

Under the terms of the New Investment Agreement, on the terms and subject to the
conditions of the New Investment Agreement, the New Investors would purchase an
aggregate of $800 million of convertible preferred stock and approximately $175
million of common stock in the reorganized Issuer as follows: (i) each New
Investor would purchase for $38.39 per share, each New Investor's proportionate
share of 4,558,479 shares of the reorganized Issuer's new common stock (the "New
Direct Subscription Shares");



(ii) each Co-Investor would purchase for $38.39 per share, each Co-Investor's
proportionate share of the reorganized Issuer's new Series B Senior Convertible
Preferred Stock (the "New Series B Preferred Stock"); and (iii) ADAH would
purchase for $31.28 per share, 12,787,724 shares of the reorganized Issuer's new
Series A-1 Senior Convertible Preferred Stock (the "New Series A-1 Preferred
Stock"). The number of New Direct Subscription Shares and New Series B Preferred
Stock to be purchased by each New Investor is set forth on Schedule 2 to the New
Investment Agreement.

Additionally, on the terms and subject to the conditions of the New Investment
Agreement, the New Investors would purchase any unsubscribed shares ("New
Unsubscribed Shares") of the reorganized Issuer's new common stock in connection
with an approximately $1.6 billion rights offering (the "Rights Offering") that
would be made available to holders of Common Stock as of a record date to be
determined by the Issuer. In accordance with the New Investment Agreement, the
Issuer would distribute certain rights to holders of Common Stock to acquire new
common stock of the reorganized Issuer subject to the effectiveness of a
registration statement to be filed with the U.S. Securities and Exchange
Commission, approval of the Bankruptcy Court and satisfaction of other terms and
conditions. The rights, which would be transferable by the original eligible
holders, would permit holders to purchase their pro rata share of new common
stock of the reorganized Issuer at $38.39 per share.

Altogether, the New Investors could invest up to an aggregate of $2.55 billion
in the reorganized Issuer. The New Investment Agreement is subject to
satisfaction and waiver of numerous conditions and the non-exercise by either
the Issuer or the New Investors of certain termination rights, all of which are
more fully described in the New Investment Agreement.

The New Investors would be entitled to payment of certain commitment fees and an
alternate transaction fee, and ADAH would be entitled to an arrangement fee, in
amounts, at the times and under the circumstances set forth in the New
Investment Agreement.

Plan of Reorganization Framework

Exhibit B attached to the New Investment Agreement further outlines the Issuer's
proposed framework for a plan of reorganization, which includes distributions to
be made to creditors and stockholders, the treatment of GM's claims, and the
corporate governance of the reorganized Issuer.

Corporate Governance Structure

As contemplated by the New Investment Agreement, the reorganized Issuer would be
governed by a nine (9) member board of directors including an executive chairman
and the Issuer's CEO. Subject to certain conditions, six of the nine directors
would be required to be independent of the reorganized Issuer under applicable
exchange rules and independent of the New Investors.

A five (5) member selection committee would have certain approval rights with
respect to the reorganized Issuer's initial Board of Directors. The selection
committee would consist of John D. Opie, the Issuer's board of directors' lead
independent director, a representative of each of the Issuer's two statutory
committees, a representative from Appaloosa and a representative from the
Co-Investors (other than UBS Securities LLC, Merrill and GS). ADAH, through its
proposed New Series A-1 Preferred Stock ownership, would have certain veto
rights regarding extraordinary corporate actions such as change of control
transactions and acquisitions or investments in excess of $250 million in any
twelve (12) month period.

Executive compensation for the reorganized company would be on market terms, as
reasonably satisfactory to ADAH. The overall executive compensation plan design
would be described in the Issuer's disclosure statement and incorporated into
the plan of reorganization.

New Investor Letter Agreement




On July 18, 2007, Appaloosa, UBS Securities LLC, Harbinger, Merrill, GS and
Pardus entered into a letter agreement (the "Letter Agreement") governing the
relationships among them. A copy of the Letter Agreement is attached hereto as
Exhibit J.

The parties to the Letter Agreement have agreed, subject to certain exceptions,
to certain transfer restrictions on claims and interests in any of the Debtors
(as defined in the New Investment Agreement). Additionally, the Letter Agreement
sets forth certain obligations of the parties to the Letter Agreement with
respect to supporting the transactions contemplated by the New Investment
Agreement on the terms and subject to the conditions contained in the Letter
Agreement.

Additional Investor Agreement

On July 23, 2007, ADAH, Del-Auto, Merrill and UBS Securities LLC (collectively,
the "Initial Investors") and certain third party additional investors (the
"Additional Investors") entered into an agreement (the "Additional Investor
Agreement"), pursuant to which, on the terms and conditions contained therein,
the Initial Investors committed to sell and the Additional Investors committed
to buy a portion of any New Direct Subscription Shares and New Unsubscribed
Shares from Initial Investors pursuant to the New Investment Agreement. The
aggregate maximum amount of New Direct Subscription Shares and New Unsubscribed
Shares that may be sold pursuant to the Additional Investor Agreement would be
approximately 16,801,235 assuming that the New Investors are required to
purchase all the shares of Common Stock pursuant to the Rights Offering.
Further, the Additional Investor Agreement provides that the Initial Investors
will share with the Additional Investors a portion of any Standby Commitment Fee
and/or Alternate Transaction Fee (as such terms are defined in the New
Investment Agreement) received by the Initial Investors. Additionally, on July
23, 2007, the Initial Investors entered into an agreement (the "Agreement Among
Initial Investors") pursuant to which the Initial Investors allocated as among
themselves the obligations to sell shares and transfer fees pursuant to the
Additional Investor Agreement. Copies of the Additional Investor Agreement and
the Agreement Among Initial Investors are attached hereto as Exhibits K and L,
respectively.

Except as described in this Item 4 or otherwise described in this Statement, the
Reporting Person currently has no plans or proposals which relate to or would
result in any transaction, event or action enumerated in paragraphs (a) through
(j) of Item 4 of the form of Schedule 13D promulgated under the Securities
Exchange Act of 1934, as amended. Subject to the terms of the New Investment
Agreement, the Reporting Person reserves the right, in light of its or his
ongoing evaluation of the Issuer's financial condition, business, operations and
prospects, the market price of the Common Stock, conditions in the securities
markets generally, general economic and industry conditions, its or his business
objectives and other relevant factors, to change its or his plans and intentions
at any time, as it or he deems appropriate. In particular, and without limiting
the generality of the foregoing (but subject to the terms of any confidentiality
agreements), the Reporting Person (and its affiliates) reserves the right, in
each case subject to any applicable limitations imposed on the sale of any of
their Common Stock by the Securities Act of 1933, as amended, or other
applicable law, to (i) purchase additional shares of Common Stock or other
securities of the Issuer, (ii) sell or transfer shares of Common Stock or other
securities beneficially owned by them from time to time in public or private
transactions and (iii) to distribute, or cause to distribute, in kind to
stockholders, partners or members, as the case may be, shares of Common Stock or
other securities owned by the Reporting Person.

This Amendment is not a solicitation for votes on the Issuer's plan of
reorganization. No disclosure statement has been approved by the Bankruptcy
Court for the Issuer's plan of reorganization.
