An Award Fund shall be established at five percent of the Company’s Adjusted

to decrease the amount of the Award Fund in any given Performance Year. No
amounts shall be paid under the SEIP for any Performance Year unless the Company
has Adjusted EBITDA in such Performance Year.

AWARDS

No later than 90 days after the commencement of each Performance Year, the
Committee shall determine the percentage of the Award Fund to allocate to each
Participant as an Award for such Performance Year; provided that for any given

Award Fund.

ADJUSTMENT AND LIMITATIONS

any Award, but the Committee reserves the right to decrease or eliminate any
Award to any Participant. In determining Awards, the Committee shall exercise
discretion only to the extent permitted in Section 162(m) of the Internal
Revenue Code and the regulations thereunder. In making such determinations, the
Committee may establish factors to take into account in implementing its
discretion, including, but not limited to, achievement of business objectives
and individual objectives, including the objectives established under the
SunCoke Energy, Inc. Annual Incentive Plan, and, except in the case of the Award
for the Chief Executive Officer of the Company, the recommendations of the Chief
Executive Officer of the Company.

paid to any Participant whose employment terminates during the Performance Year
as a result of death, permanent disability (as determined under the Company’s
long term disability program) or Retirement.

Any pro-rated Award for the Performance Year payable hereunder will be paid on
the date when Awards are otherwise payable for such Performance Year as provided
in the SEIP.

the SunCoke Energy, Inc. Executive Annual Incentive Plan.

EFFECTIVE DATE; AMENDMENT OR TERMINATION

Effective Date. The SEIP shall be effective for Performance Years beginning on

--------------------------------------------------------------------------------

Amendment or Termination. The SEIP may be amended or revised at any time by the
Committee and may be discontinued or terminated in whole or in part at any time
by the Board of Directors of the Company, provided, however, that no amendment
requiring shareholder approval under Section 162(m) of the Internal Revenue Code
will be made without obtaining such shareholder approval. The SEIP will continue
in operation until discontinued or terminated as herein provided.

MISCELLANEOUS

Neither the action of the Company in establishing the SEIP, nor any action taken
by it or by the Committee under the provisions hereof, nor any provision of the
SEIP, shall be construed as giving to any Participant the right to be retained
in the employ of the Company or its Affiliates.

The Company may offset against any payments to be made to a Participant or
his/her beneficiary under the SEIP any amounts owing to the Company or
Affiliates from the Participant for any reason.

Nothing in the SEIP shall obligate the Company to set aside funds to pay for the
Awards determined hereunder, or to pay Awards under the SEIP.

The validity, construction and effect of the SEIP or any incentive payment
payable under the SEIP shall be determined in accordance with the laws of the
State of Delaware.

The Company shall have the right to make all payments or distributions pursuant
to the SEIP to a Participant, net of any applicable Federal, State and local
taxes required to be paid or withheld. The Company shall have the right to
withhold from wages, Award payments or other amounts otherwise payable to such
Participant such withholding taxes as may be required by law, or to otherwise
require the Participant to pay such withholding taxes.

The SEIP shall be binding upon and inure to the benefit of the Company and its
successors and assigns.
