This information has not been updated to reflect changes in the ownership by such parties of AIG Shares that are disclosed in filings made by one or more of such parties under Section 16 of the Securities Exchange Act of 1934, as amended ("Act"). In each case, such information may not be accurate or complete and AIG takes no responsibility therefor and makes no representation to its accuracy or completeness as of the date hereof or any subsequent date. (d) and (e): 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.

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.
