by the Reporting Persons on September 2, 2008 ("Amendment No. 1"), Amendment No.
2 to Schedule 13D filed by the Reporting Persons on September 10, 2008

Persons on October 28, 2008 ("Amendment No. 3" and, together

PURPOSE

amended and restated in its entirety as follows:
On
December 14, 2008, the Issuer announced that it had terminated its proposed
merger agreement with Hexion and executed a settlement agreement with Hexion,
Apollo Management and certain related parties. In light of the
termination of the merger with Hexion, the Reporting Persons plan to sell Common
Shares and unwind total return equity swaps on the Common Shares, although this
plan may change as a result of a change in market conditions and other
developments.

positions; each such option was previously acquired in open market
transactions.
