          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 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


                                  Page 8 of 15



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 Act, 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.



                                  Page 9 of 15


          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.

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

          Not applicable.

ITEM 4. PURPOSE OF TRANSACTION.

          On September 26, 2008, AIG publicly announced that it was exploring
all strategic alternatives in connection with the potential disposition or other
monetization of its and the other Reporting Persons' interests in the Company.
In response to certain strategic alternatives communicated by AIG to the
Company, the board of directors of the Company formed a special committee of its
board of directors consisting of directors who are independent of AIG and the
management of AIG to consider such strategic alternatives, as well as to explore
and consider any potential merger, third-party tender offer or other business
combination involving all of the outstanding shares of Common Stock of the
Company.

          On May 28, 2009, the Company filed a prospectus supplement to the
prospectus contained in Post-Effective Amendment No. 1 to its registration
statement on Form S-3 (the "Registration Statement") with the Securities and
Exchange Commission (the "SEC") covering a public offering of up to 26 million
shares of Common Stock of the Company held by AIG and AHAC (plus up to an
additional 3.9 million shares of Common Stock subject to the Underwriters' (as
defined below) 30-day option) (the "Offering").

          Concurrently with the filing of the Registration Statement, AIG, AHAC
and the Company entered into a master separation agreement (including the
exhibits thereto, the "Separation Agreement"), to effect the orderly separation
of AIG, AHAC and the Company. A copy of the Separation Agreement and certain
exhibits thereto are filed as an exhibit to Amendment No. 17 to the Statement on
Schedule 13D, dated May 28, 2009 and is incorporated by reference to this
Item 4.

          On June 4, 2009 AIG, AHAC and the Company entered into an underwriting
agreement (the "Underwriting Agreement") with  J.P. Morgan Securities Inc. and
Goldman, Sachs & Co. as representatives of the several underwriters (the
"Underwriters"), which is filed as an exhibit to this Schedule 13D and
incorporated by reference to this Item 4. Pursuant to the Underwriting
Agreement, each of AIG and AHAC have agreed to sell to the Underwriters an
aggregate of 26 million shares of Common Stock of the Company at a price of
$38.00 per share, and on June 5, 2009 the Underwriters exercised their option to
purchase an additional 3.9 million shares of Common Stock. At the completion of
the Offering, AIG and AHAC will own 9,193,341 shares of Common Stock,
representing 13.9% of the Common Stock of the Company. AIG and AHAC will
continue to explore all strategic alternatives in connection with the potential
disposition or other monetization of their remaining shares of Common Stock of
the Company

          Concurrently with the execution of the Underwriting Agreement, AIG,
AHAC and the Company closed the transactions contemplated in the Separation
Agreement (the "Closing"). At the Closing, AIG, AHAC and the Company entered
into a registration rights agreement, in substantially the form attached as
Exhibit C to the Separation Agreement (the "Rights Agreement"), which will
become effective upon completion of the Offering, pursuant to which the Company
will grant to AIG and AHAC certain rights to require the Company to register
with the SEC any of AIG's and AHAC's respective shares of Common Stock of the
Company that were not sold in the Offering (either by a shelf registration which
must be kept effective, or if a shelf registration is not available, a newly
filed registration statement). Under the Rights Agreement, the registration must
contemplate the right of AIG and AHAC to offer their respective shares of Common
Stock of the Company in subsequent underwritten offerings.


                                 Page 10 of 15



          In addition, at the Closing, each of the Company, AIG and AHAC entered
into a stockholders agreement, in substantially the form attached as Exhibit E
to the Separation Agreement, which among other things, provides certain
information rights to AIG and AHAC, post-Closing and imposes certain transfer
andstandstill restrictions on AIG, AHAC, their respective affiliates and their
respective directors and officers as set forth therein. The stockholders
agreement will become effective upon completion of the Offering.

          Also at the Closing, in their capacity as holders of a majority of the
Common Stock, AIG and AHAC executed a consent to restate the Company's
certificate of incorporation to increase the number of authorized shares of
Common Stock and preferred stock that the Company may issue and to effect other
changes as set forth in the Company's Restated Certificate of Incorporation. The
Company will file with the Secretary of State of the State of Delaware the
Restated Certificate of Incorporation, in the form attached as Exhibit H to the
Separation Agreement.

          The foregoing descriptions of the Underwriting Agreement and certain
provisions of the Separation Agreement and certain exhibits to the Separation
Agreement are qualified in their entirety by reference to the the Underwriting
