("PNC"), the marketing of transactions similar to the PNC transactions and related matters. -3- AIG, without admitting or denying the allegations in the SEC complaint, consented to the issuance of a final judgment: (a) permanently enjoining it and its employees and related persons from violating section 10(b) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), Exchange Act Rule 10b-5, and Section 17(a) of the Securities Act of 1933, as amended (the "Securities Act"), and from aiding and abetting violations of Sections 13(a) and 13(b)(2)(A) of the Exchange Act and Exchange Act Rules 12b-20, 13a-1, and 13a-13; (b) ordering it to disgorge the $39,821,000 in fees that it received from the PNC transactions, plus prejudgment interest of $6,545,000; and (c) 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 settlement with the DOJ consists of separate agreements with AIG and AIGFP and a complaint filed against, and deferred prosecution agreement with, AIGFP PAGIC Equity Holding Corp. ("AIGFP PAGIC"), a wholly-owned subsidiary of AIGFP. Under the terms of the settlement, AIGFP paid a monetary penalty of $80 million and, provided that AIG, AIGFP and AIGFP PAGIC satisfy their obligations under the DOJ agreements, the DOJ will seek a dismissal with prejudice of the AIGFP PAGIC complaint after 13 months and will not prosecute AIG or AIGFP in connection with the PNC transactions or the Brightpoint transaction that was settled by AIG with the SEC in 2003. 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. AIG used its available working capital to make the purchase described in the response to Item 4 of this Amendment. In the event an action described in the last paragraph of Item 4 occurs after the date hereof, the source and amount of any funds used by AIG will depend on the nature and timing of the action. Item 4. Purpose of Transaction. The purpose of the acquisition of the Common Shares by AIG was for investment. On October 31, 2005, the Company entered into a letter agreement (the "Letter Agreement") with AIG. Under the Letter Agreement, the Company agreed to issue and sell directly to AIG an aggregate of 3,341,000 Common Shares concurrently with a public offering of the Common Shares by the Company, and up to an additional 334,000 Common Shares in the event that the underwriters exercise their over-allotment option in the offering, in each case at the public offering price. On November 4, 2005, AIG completed the purchase of 3,675,000 Common Shares at $26.25 per share, which included the Common Shares issuable upon the exercise of the underwriters' over-allotment option. AIG's purchase of the Common Shares was designed to maintain AIG's percentage ownership of the Common Shares at approximately 24%. In the Letter Agreement, the Company has also agreed to provide AIG with certain demand registration rights covering the Common Shares owned by AIG prior to November 4, 2005 and the Common Shares that AIG that acquired on November 4, 2005 -4- pursuant to the Letter Agreement, in all cases for seven years following termination of the lock-up period described below. The lock-up period is documented in a separate letter agreement (the "Lock-Up Letter"), dated as of October 25, 2005, by and among Citigroup Global Markets Inc. and Morgan Stanley & Co. Incorporated (together, the "Managers") and AIG. Pursuant to the Lock-Up Letter, among other things, AIG agreed that, for a period ending 60 days after October 31, 2005, AIG will not, without the prior written consent of the Managers: (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any Common Shares or any securities convertible into or exercisable or exchangeable for Common Shares, or (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, the economic consequences of ownership of the Common Shares, regardless of whether any such transaction described in (i) or (ii) above is to be settled by delivery of Common Shares or other securities, in cash or otherwise. The demand registration rights set forth in the Letter Agreement are being provided by the Company to AIG on the terms and subject to the conditions specified with respect to demand registration rights held by AIG pursuant to the previously in-effect Registration Rights Agreement, dated as of March 13, 1996 (the "Registration Rights Agreement"), by and between the Company and certain rightholders set forth therein. Under the Registration Rights Agreement, AIG has the right, on a specified number of occasions, to require the Company to register Common Shares under the Securities Act. In the Letter Agreement, AIG has agreed to pay all of the Company's out-of-pocket expenses (as well as bear its own expenses) in connection with the performance by the Company of its registration obligations under the Letter Agreement.
