Except as otherwise provided herein, during the past five years none of the Reporting Person, CS Hldgs USA Inc, CS USA Inc, CS Sec USA LLC, CS Int Hldg AG, CS Inv UK, CS Int, CS Inv Hldgs UK nor CS Sec Eur Ltd nor, to the best knowledge of the Reporting Person, any of the other persons listed on Schedules A-1 through A-9 attached hereto, has been (i) convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to United States federal or state securities laws or finding any violation with respect to such laws.

On January 22, 2002, CSFBC, without admitting or denying any alleged violation, entered into coordinated settlements with NASD Regulation, Inc. ("NASDR") and the Securities and Exchange Commission ("SEC") resolving all outstanding investigations of CSFBC into the allocation of shares in initial public offerings ("IPOs"). CSFB-USA was then the sole stockholder of CSFBC.

CSFBC consented to these settlements without admitting or denying any of the allegations made in the SEC's Complaint or the Letter of Acceptance, Waiver and Consent ("AWC") filed with the NASDR. The SEC and NASDR alleged that, between April 1999 and June 2000, certain CSFBC employees allocated many shares in IPOs to over 100 customers with whom they had improper profit-sharing arrangements. The NASDR and SEC alleged that certain employees allocated "hot" IPO shares to certain customers who paid the Firm a portion of the profits (between 33 and 65 percent) that they made when they sold their IPO stock, by paying inflated brokerage commissions on transactions unrelated to the IPO shares.

Under the terms of the coordinated settlement:

CSFBC paid a total of $100 million. This amount included $30 million in fines and civil penalties divided evenly between the SEC and NASDR, and a total of $70 million in disgorgement, $35 million of which was paid to the U.S. Treasury and $35 million of which was paid to the NASDR, representing the monies obtained as a result of the conduct described by the SEC and NASDR. The SEC determined in this case that it was appropriate and in the public interest to pay funds to the U.S. Treasury rather than to any third parties.

CSFBC has adopted and implemented revised policies and procedures for allocating IPOs in its broker-dealer operations. The SEC and NASD have reviewed these policies and procedures. These included the establishment of an IPO Allocation Review Committee, a process for the pre-qualification of accounts before they are eligible to receive IPO allocations and enhanced supervisory procedures, which includes the review of commissions paid by certain accounts receiving allocations around the time of the IPO. CSFBC also agreed to retain an independent consultant to review the implementation of these policies and procedures one year from the date of the settlement.

In the NASDR settlement, CSFBC, without admitting or denying any findings, consented to a censure and findings that it violated NASD Rules 2110, 2330, 2710, 3010 and 3110. These Rules (a) require broker-dealers to adhere to just and equitable principles of trade, (b) prohibit broker-dealers from sharing in the profits of client accounts except as specifically provided, (c) require a managing underwriter to file certain information that may have a bearing on the NASDR's review of underwriting arrangements, (d) require members to establish, maintain and enforce a reasonable supervisory system, and (e) require broker-dealers to maintain certain books and records.

The NASDR AWC also found violations of Section 17(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and SEC Rule 17a-3, thereunder, which are incorporated by NASD Rule 3110 and similarly impose certain record keeping requirements on CSFBC as a broker-dealer. In the SEC settlement, CSFBC, without admitting or denying the allegations of the Complaint, consented to entry by the District Court for the District of Columbia of a final judgment that: (1) permanently enjoined CSFBC, directly or indirectly, from violations of NASD Conduct Rules 2110 and 2330 and Section 17(a)(1) of the Exchange Act and SEC Rule 17a-3; and (2) ordered CSFBC to comply with certain undertakings.

Neither the SEC nor NASDR made any allegations or findings of fraudulent conduct by CSFBC. Further, neither the SEC nor NASDR alleged that any IPO prospectus was rendered false or misleading by CSFBC's conduct or that this conduct affected either the offering price of an IPO or the price at which any IPO stock traded in the aftermarket.

On August 13, 2002, Mr. John A. Ehinger, an executive officer of CSFB-USA and board member of CSFB LLC, without admitting or denying any alleged violation, entered into a settlement with the NASD resolving outstanding investigations of Mr. Ehinger into his alleged failure to supervise with a view toward preventing CSFBC's violations of NASD Rules 2110, 2330, 2710 and 3110, and Section 17(a) of the Exchange Act and SEC Rule 17a-3 thereunder. Under the terms of the settlement, Mr. Ehinger agreed to (1) the payment of a fine of $200,000, (2) a suspension from associating with a member firm in any and all capacities for 30 calendar days, and (3) a suspension from acting in any supervisory capacity for 30 additional calendar days, such supervisory suspension beginning after the suspension in all capacities had been served.

On October 31, 2003, the U.S. District Court for the Southern District of New York (the "SDNY") approved the global settlement among a number of Wall Street firms, including CSFB LLC, and a coalition of state and federal regulators and self-regulatory organizations (the "Global Settlement"). CSFB LLC, without admitting or denying any alleged violation, consented to the Global Settlement and thereby resolved a Securities and Exchange Commission's ("SEC") complaint filed on April 28, 2003, in the SDNY. In this complaint, the SEC alleged that, from July 1998 to December 2001, CSFB LLC engaged in acts and practices that created or maintained inappropriate influence over research analysts, thereby imposing conflicts of interest on research analysts that CSFB LLC failed to manage in an adequate or appropriate manner. The SEC's complaint also alleged that CSFB LLC engaged in inappropriate "spinning" of "hot" IPO allocations in violation of New York Stock Exchange ("NYSE") and NASD Inc. ("NASD") rules requiring adherence to high business standards and just and equitable principles of trade, and that CSFB LLC 's books and records relating to certain transactions violated the broker-dealer record-keeping provisions of Section 17(a) of the Securities Exchange Act of 1934, NYSE Rules 401, 440 and 476(a)(6) and NASD Rules 2110 and 3110.

Under the terms of the Global Settlement:

CSFB LLC agreed to pay the following amounts: $75 million as a penalty, $75 million as disgorgement of commissions and other monies for restitution for investors, and $50 million to be used to fund independent research. This $50 million to fund independent research is payable over a five year period.

CSFB LLC is required, among other things, to: (i) separate its research and investment banking departments and make independent research available to investors, (ii) prohibit its analysts from receiving compensation for investment banking activities and prohibit analysts' involvement in investment banking "pitches" and "roadshows," (iii) contract, for a five-year period, with no fewer than three independent research firms that will make available independent research to CSFB LLC's customers, and (iv) make its analysts' historical price targets (among other things) publicly available.

CSFB LLC is permanently restrained and enjoined from violating Sections 15(c) and 17(a) of the Exchange Act, Exchange Act Rules 15c1-2 and 17a-3, NASD Rules 2110, 2210, 3010, and 3110, and NYSE Rules 342, 401, 440, 472, and 476.

Other Wall Street firms were subject to similar requirements.
