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) Grant of restricted stock units issued pursuant to the Issuer's 2009 Emergence Incentive Plan and settled in accordance with the Issuer's EIP Settlement Plan, each as approved by the U.S. Bankruptcy Court for the Southern District of New York and the Organization, Compensation and Governance Committee of the Issuer's board of directors. The restricted stock units vest in three equal installments including the date of grant, March 31, 2011 and March 31, 2012. Due to an administrative error in the application of the express terms of the EIP Settlement Plan, the Form 4 originally filed to report this transaction did not correctly reflect the number of restricted stock units covered by the grant. As such, the number of reported shares underlying the restricted stock units has been revised by this amendment.
(2) The EIP Settlement Plan, as approved by the U.S. Bankruptcy Court for the Southern District of New York and the Organization, Compensation and Governance Committee of the Issuer's board of directors, provides that the base number of nonqualified stock options to be granted in settlement of awards under the 2009 Emergence Incentive Plan would be determined using a stock price of $13.45 and also provides that the exercise price of the nonqualified stock options would be the closing price of the Issuer's stock on the date the nonqualified stock options were granted, which was $15.50. Due to an administrative error in the application of the express terms of the EIP Settlement Plan, the Form 4 originally filed to report this transaction did not correctly reflect the $15.50 exercise price and the number of shares underlying the nonqualified stock options. As such, the exercise price and the number of shares underlying the nonqualified stock options have been revised by this amendment.
(3) The stock options vest in three equal installments, including the date of grant, March 31, 2011 and March 31, 2012.

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