Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Citadel Equity Fund Ltd., Citadel Credit Trading Ltd. and Citadel Derivatives Group LLC each hold shares of the Issuer's common stock both directly and indirectly. However, because the form does not permit joint filers to indicate both direct and indirect ownership, indirect ownership has been selected, as it applies to the additional reporting persons as well.
(2) Citadel Limited Partnership ("Citadel") is the portfolio manager of each of Citadel Equity Fund Ltd. and Citadel Credit Trading Ltd. and is the managing member of Citadel Derivatives Group LLC. Consequently, Citadel may be deemed to have voting control and investment discretion over securities held by each of Citadel Equity Fund Ltd., Citadel Credit Trading Ltd. and Citadel Derivatives Group LLC. Citadel disclaims beneficial ownership of the shares beneficially owned by Citadel Equity Fund Ltd., Citadel Credit Trading Ltd. and Citadel Derivatives Group LLC. Each of the other persons jointly filing this Form 4 may be deemed to indirectly control one or more of Citadel Equity Fund Ltd., Citadel Credit Trading Ltd. and Citadel Derivatives Group LLC and may be deemed to have a pecuniary interest in such shares and disclaims beneficial ownership of the shares held by Citadel Equity Fund Ltd., Citadel Credit Trading Ltd. and Citadel Derivatives Group LLC.
 
Remarks:
Between July 11, 2005 and July 26, 2005, Citadel Derivatives Group LLC inadvertently permitted its automated trading program to make purchases and sales of the Issuer's common stock.  Upon discovery of the mistake, Citadel Derivatives Group LLC is disgorging to the Issuer the full amount of the short swing profits relating to such transactions, totaling $9,674.26, calculated in accordance with Section 16 of the Securities Exchange Act of 1934, as amended.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
