                    INFORMATION TO BE INCLUDED IN THE REPORT


Item 2.05  Costs Associated with Exit or Disposal Activities.
           -------------------------------------------------

           The Board of Directors of Sterling Chemicals, Inc. (the "Company")
has determined that the Company will exit the acrylonitrile and related
derivatives businesses. The Board of Directors committed the Company to the exit
from such businesses on September 15, 2005 based on the circumstances as
generally described in the press release issued September 16, 2005 filed
herewith as Exhibit 99.1 and incorporated herein by reference.

           An estimated range of the total amounts expected to be incurred in
connection with the exit from these businesses, along with an estimate of the
amounts of the major types of cost associated with such exit, is set forth in
the attached press release. The Company does not expect the exit from these
businesses to result in any future capital expenditures, and the press release
provides the Company's estimate of the amount of future reduced capital
expenditures associated with such exit.

Item 2.06  Material Impairments.
           --------------------

           In connection with the exit from the acrylonitrile and related
derivatives businesses (as determined by the Board of Directors as described
above), the Company will record an impairment charge. The conclusion that such
an impairment charge is required was made by the Company on September 15, 2005
in connection with the Board of Directors determination that the Company will
exit these businesses and was based on the same general circumstances that
provided a basis for the exit determination (as described in the attached press
release). An estimate of the amount of the impairment charge is set forth in the
attached press release, and the Company does not expect the impairment charge to
result in any future capital expenditures.
