W I T N E S S E T H:
WHEREAS, the SunCoke Energy, Inc. Long-Term Performance Enhancement Plan (the
“Plan”) is administered by the Compensation Committee (the “Committee”), and the
Committee has determined to grant to the Participant, pursuant to the terms and
conditions of the Plan, an award (the “Award”) of Performance Share Units

Committee for the applicable performance period and the Participant’s continued
employment with SunCoke or one of its Affiliates through the Determination Date
(as defined herein); and
WHEREAS, the Participant has determined to accept such Award.
NOW, THEREFORE, in consideration of these premises and the mutual promises of
each of the Parties herein contained, and for other good and valuable

shareholder return (“TSR”), relative to the NASDAQ U.S. Benchmark Iron & Steel
Total Return Index, as more particularly described on “Exhibit A,” attached

corporate cost, but excluding discontinued operations and legacy costs [e.g.,
Black Lung, pensions and other post-employment benefits] (“ROIC”), and further
adjusted for TSR, relative to the

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

NASDAQ U.S. Benchmark Iron & Steel Total Return Index, as more particularly
described on “Exhibit A,” attached hereto.
(d)
Performance Period: Three-year period beginning on January 1, 2018 and ending on

meanings ascribed to them in the Plan.
1.2    Award of PSUs. Subject to the terms and conditions of the Plan and this
Agreement, the Participant is hereby granted the target number of total PSUs set
forth in Section 1.1.
1.3    Dividend Equivalents. The Participant shall be entitled to receive
payment from SunCoke in an amount equal to each cash dividend (“Dividend

Participant, on the record date for payment of such dividend, had been the
holder of record of shares of Common Stock equal to the target number of PSUs.
SunCoke shall establish a bookkeeping methodology to account for the Dividend
Equivalents to be credited to the Participant. The Dividend Equivalents will not
bear interest.
1.4    Adjustment, Vesting and Payment of PSUs and Dividend Equivalents.
(a)    Adjustment.
(1)    The target number of total PSUs subject to each PSU Award shall be
adjusted by the Committee after the end of the Performance Period, based on the
level of achievement of the performance goal(s) established with respect to the
Performance Period as set forth in the attached Exhibit A. The date that the
Committee determines the level of performance goal achievement applicable to the
Award is the “Determination Date”.
(2)    Dividend Equivalents will be subject to the same adjustment, determined
by multiplying the amount of Dividend Equivalents as of the Determination Date
by the percentage adjustment made to the PSUs.
(b)    Vesting. Except as set forth in Section 1.5(b), (c) and (d) below, a
Participant shall become vested in this PSU Award and related Dividend
Equivalents on the Determination Date, if the Participant remains in continuous
employment with SunCoke or one of its Affiliates until the Determination Date.
PSUs and Dividend Equivalents that do not vest shall be forfeited.
(c)    Payment. Except as set forth in Section 1.5(b) and (c) below, actual
payment for vested PSUs and vested Dividend Equivalents shall be made to the
Participant within one month after the Determination Date.
(1)    Payment for vested PSUs. Payment for vested PSUs shall be made in shares
of Common Stock. The number of shares of Common Stock paid to the Participant
shall be equal to the aggregate total number of PSUs that vest on the
Determination Date.
(2)    Payment of Related Dividend Equivalents. Payment for the vested Dividend
Equivalents will be made in cash.
1.5    Termination of Employment.
(a)    Termination of Employment - In General. Upon termination of the
Participant’s employment with SunCoke and its Affiliates prior to the
Determination Date for any reason other than a Qualifying Termination or due to
death or permanent disability, the Participant shall forfeit 100% of such
Participant’s PSUs, together with the related Dividend Equivalents, and the
Participant shall not be entitled to receive any Common Stock or any payment of
any Dividend Equivalents with respect to the forfeited PSUs.

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

(b)    Qualifying Termination of Employment. In the event of the Participant’s
Qualifying Termination prior to the Determination Date, the Participant’s
outstanding PSUs and Dividend Equivalents shall vest immediately as follows:
(i)    For the PSUs (Adj. EBITDA): at the higher of (A) the target level, or (B)
the actual performance level attained for Adj. EBITDA; and
(ii)    For the PSUs (ROIC): at the higher of (A) the target level, or (B) the
actual performance level attained for ROIC,
in each case, calculated as of the fiscal quarter ending on, or immediately

of the date of the Change in Control), relative to the NASDAQ U.S. Benchmark
Iron & Steel Total Return Index, as more particularly described on “Exhibit A,”
attached hereto. Each of such vested PSUs (Adj. EBITDA) and PSUs (ROIC) shall be
paid in the form described in Section 1.4(c) above within one month following
such Qualifying Termination.
(c)    Termination of Employment Due to Death or Permanent Disability. In the
event of the Participant’s termination of employment due to death or permanent
disability prior to the Determination Date, the Participant’s outstanding PSUs
and Dividend Equivalents shall vest immediately at the target level and be paid
in the form described in Section 1.4(c) above within one month following such
termination of employment.
(d)    Termination Due to Retirement. In the event of the Participant’s
termination of employment with SunCoke and its Affiliates prior to the
Determination Date due to Retirement, the Participant’s PSUs and Dividend
Equivalents shall remain outstanding and shall be adjusted at the end of the
performance period as described in Section 1.4. The Participant shall vest in a
pro rata portion of the adjusted PSUs determined by multiplying the number of
PSUs by a fraction, the numerator of which is the number of full months that
have elapsed from the beginning of the performance period to the employment
termination date and the denominator of which is the number of full months in
the performance period. The Participant also shall vest in the adjusted pro rata
portion of the related Dividend Equivalents. The Participant’s PSUs and Dividend
Equivalents that vest shall be paid in the form described in Section 1.4(c)
above within one month following the Determination Date.
For purposes of this Section 1.5,
(i)    a Participant’s termination of employment shall not be deemed to be a
“Retirement” unless: (x) such termination is other than for Just Cause; (y) the
Participant has attained at least 55 years of age; and (z) the Participant’s
age, when added to such Participant’s years of credited service with the SunCoke
and/or its Affiliates, equals at least 65 years; and
(ii)    a Participant shall have a “permanent disability” if such Participant is
found to be disabled, under the terms of SunCoke’s long-term disability policy
in effect at the time of the Participant’s termination, due to such condition or
if the Committee in its discretion makes such determination.
