     Item 2(d) and (e) of the Schedule 13D is hereby amended and restated to

     2006 Regulatory Settlements

     In February 2006, AIG reached a final settlement with the Securities and
Exchange Commission ("SEC"), the United States Department of Justice ("DOJ"),
the Office of the New York Attorney General ("NYAG") and the New York State
Department of Insurance ("DOI"). The settlements resolved outstanding litigation
filed by the SEC, NYAG and DOI against AIG and concluded negotiations with these
authorities and the DOJ in connection with the accounting, financial reporting
and insurance brokerage practices of AIG and its subsidiaries, as well as claims
relating to the underpayment of certain workers compensation premium taxes and
other assessments. As a result of these settlements, AIG made payments or placed
amounts in escrow in 2006 totaling approximately $1.64 billion, $225 million of
which represented fines and penalties. The following is additional information
regarding the settlements.

     AIG, without admitting or denying the allegations in the SEC complaint,
consented to the issuance of a final judgment on February 9, 2006: (a)
permanently restraining and enjoining AIG from violating Section 17(a) of the
Securities Act of 1933, as amended ("Securities Act"), and Sections 10(b),
13(a), 13(b)(2) and 13(b)(5) and Rules 10b-5, 12b-20, 13a-1, 13a-13 and 13b2-1
of the Exchange Act; (b) ordering AIG to pay disgorgement; and (c) ordering AIG
to pay a civil penalty.

     In February 2006, AIG and the DOJ entered into a letter agreement. In the
letter agreement, the DOJ notified AIG that in its view, AIG, acting through
some of its employees, violated federal criminal law in connection with
misstatements in periodic financial reports that AIG filed with the SEC between
2000 and 2004 relating to certain transactions. The settlement with the DOJ
consists of, among other things, AIG's cooperating with the DOJ in the DOJ's
ongoing criminal investigation, accepting responsibility for certain of its
actions and those of its employees relating to these transactions and paying
money into a fund. Also effective February 9, 2006, AIG entered into agreements
with the NYAG and the DOI, settling claims under New York's Martin Act and
insurance laws, among other provisions, which were originally brought by the
NYAG and the DOI in a civil complaint filed on May 26, 2005.

     As part of these settlements, AIG has agreed to retain for a period of
three years an independent consultant who will conduct a review that will
include the adequacy of AIG's internal controls over financial reporting and the
remediation plan that AIG has implemented as a result of its own internal
review.

     PNC Settlement

     In November 2004, AIG and AIG Financial Products Corp. ("AIGFP"), a
subsidiary of AIG, reached a final settlement with the SEC, the Fraud Section of
the DOJ and the United States Attorney for the Southern District of Indiana with
respect to issues arising from certain structured transactions entered into with
Brightpoint, Inc. and The PNC Financial Services Group, Inc. ("PNC"), the
marketing of transactions similar to the PNC transactions and related matters.

     As part of the settlement, the SEC filed against AIG a civil complaint,
based on the conduct of AIG primarily through AIGFP, alleging violations of
certain antifraud provisions of the federal securities laws and for aiding and
abetting violations of reporting and record keeping provisions of those laws.
AIG, without admitting or denying the allegations in the SEC complaint,
consented to the issuance of a final judgment permanently enjoining it and its
employees and related persons from violating certain provisions of the Exchange
Act, Exchange Act rules and the Securities Act, ordering disgorgement of fees it
received from the PNC transactions and providing for AIG to establish a
transaction review committee to review the appropriateness of certain future
transactions and to retain an independent consultant to examine certain
transactions entered into between 2000 and 2004 and review the policies and
procedures of the transaction review committee.

     The DOJ filed against AIGFP PAGIC Equity Holding Corp. ("AIGFP PAGIC"), a
wholly owned subsidiary of AIGFP, a criminal complaint alleging that AIGFP PAGIC
violated federal securities laws by aiding and abetting securities law
violations by PNC, in connection with a transaction entered into in 2001 with
PNC that was intended to enable PNC to remove certain assets from its balance
sheets. The settlement with the DOJ consists of separate agreements with AIG and
AIGFP and a complaint filed against, and deferred prosecution agreement with,
AIGFP PAGIC. Under the terms of the settlement, AIGFP paid a monetary penalty of
$80 million. On January 17, 2006, the court approved an order dismissing the
complaint with prejudice. The obligations of AIG, AIGFP and AIGFP PAGIC under
the DOJ agreements relate principally to cooperating with the DOJ and other
federal agencies in connection with their related investigations.
