ARTICLE III

OPTIONS

With respect to Adjusted Awards, the provisions below will be applicable only to the extent that they are not inconsistent with the Separation Agreement and the terms of the Adjusted Award assumed under the Separation Agreement:

3.1 Award of Options. The Committee, from time to time, and subject to the provisions of the Plan and such other terms and conditions as the Committee may prescribe, may grant to any Participant one or more options (not intended to qualify as “incentive stock options” under section 422 of the Code) (“Options”) to purchase the number of Shares allotted by the Committee. The “Grant Date” for each Option shall be the date of the Committee action to make the Award or, if later, the date selected by the Committee as the date of grant of the Option pursuant to the Plan; provided, however, that with respect to any Adjusted Award, Grant Date shall mean the initial date on which an Adjusted Award was granted under the applicable Sunoco Long-Term Incentive Plan.

3.2 Option Agreements. The grant of an Option shall be evidenced by a written Option agreement, executed by the Company and the holder of an Option, stating the number of Shares subject to the Option evidenced thereby, the vesting terms, the treatment of the Option upon a Participant’s termination of employment, and such other provisions as the Committee may from time to time determine.

3.3 Exercise Price. The Exercise Price shall be not less than the Fair Market Value on the Grant Date. In no event may any Option granted under this Plan be amended, other than pursuant to Section 6.8, to decrease the exercise price thereof, be cancelled in conjunction with the grant of any new Option with a lower exercise price or otherwise be subject to any action that would be treated, for accounting purposes, as a “repricing” of such Option, unless such amendment, cancellation, or action is approved by the Company’s stockholders.

SunCoke Energy, Inc.

Long-Term Performance Enhancement Plan

Page 10 of 18

3.4 Term and Exercise. The term and the vesting schedule of each Option shall be determined by the Committee. No Option shall be exercisable after the expiration of its term and the maximum term of any Option shall be ten years.

3.5 Transferability.

(a) No Option may be transferred by the Participant other than by will, by the laws of descent and distribution or, to the extent not inconsistent with the applicable provisions of the Code, pursuant to a domestic relations order under applicable provisions of law, and during the Participant’s lifetime the Option may be exercised only by the Participant; provided, however, that, subject to such limits as the Committee may establish, the Committee, in its discretion, may allow the Participant to transfer an Option for no consideration to, or for the benefit of, an Immediate Family Member or to a bona fide trust for the exclusive benefit of such Immediate Family Member, or a partnership or limited liability company in which Immediate Family Members are the only partners or members.

(b) A transfer pursuant to Section 3. 5(a) may only be effected following advance written notice from the Participant (or Participant’s estate) to the Committee, describing the terms and conditions of the proposed transfer, and such transfer shall become effective only when recorded in the Company’s record of outstanding Options. Any such transfer pursuant to Section 3. 5(a) is further conditioned on the Participant and such Immediate Family Member or other transferee agreeing to abide by the Company’s then-current Option transfer guidelines. In the discretion of the Committee, the right to transfer an Option pursuant to Section 3. 5(a) also will apply to the right to transfer ancillary rights associated with such Option, and to the right to consent to any amendment to the applicable Option agreement.

(c) Subsequent transfers by a transferee pursuant to Section 3. 5(a) shall be prohibited except in accordance with the laws of descent and distribution, or by will.

(d) Following any transfer pursuant to this Section 3.5, any transferred Option shall continue to be subject to the same terms and conditions as were applicable immediately prior to transfer, and the terms “Optionee” or “Participant” shall be deemed to include the transferee; provided, however, that the terms governing exercisability of an Option that apply following any events of termination of employment shall apply based on the employment status of the original Optionee. Neither the Committee nor the Company will have any obligation to inform any transferee of an Option of any expiration, termination, lapse or acceleration of such Option. The Company will have no obligation to register with any federal or state securities commission or agency any Shares issuable or issued under an Option that has been transferred by a Participant under this Section 3.5.

3.6 Manner of Payment. Each Option agreement shall set forth the procedure governing the exercise of the Option granted thereunder, and shall provide that, upon such exercise in respect of any Shares subject thereto, the Optionee shall pay to the Company, in full, an amount (such amount, the “Aggregate Exercise Price”) equal to the product of (a) the Exercise Price, and (b) the number of Shares with respect to which Optionee exercises the Option (together with payment for any taxes which the Company is required by law to withhold

SunCoke Energy, Inc.

Long-Term Performance Enhancement Plan

Page 11 of 18

by reason of such exercise) with cash or with Shares. A Participant may pay the Aggregate Exercise Price with respect to an Option that the Participant exercises through the delivery of Shares owned by the Optionee, or by foregoing delivery of Shares subject to the Option, in each case having an aggregate Fair Market Value (as determined as of the date prior to exercise) equal to the Aggregate Exercise Price; provided, however, that any use of Shares to satisfy the Aggregate Exercise Price in accordance with this provision must be in compliance with then-applicable accounting rules.

3.7 Issuance and Delivery of Shares. As soon as practicable after receipt of payment, the Company shall deliver to the Optionee a certificate or certificates for, or otherwise register the Optionee on the books and records of the Company as a holder of, such Shares. The Optionee shall become a shareholder of the Company with respect to the Shares so registered, or represented by Share certificates so issued, and as such shall be fully entitled to receive dividends, to vote and to exercise all other rights of a shareholder except to the extent otherwise provided in the Option agreement.

3.8 Section 162(m) of the Code. The provisions of this Plan are intended to ensure that all Options granted hereunder to any Participant who is or may be a “covered employee” (within the meaning of Section 162(m)(3) of the Code) in the tax year in which such Option is expected to be deductible to the Company qualify for the Section 162(m) Exemption, and all such Awards shall therefore be considered Qualified Performance-Based Awards and this Plan shall be interpreted and operated consistent with that intention.

ARTICLE IV

SHARE UNITS

With respect to Adjusted Awards, the provisions below will be applicable only to the extent that they are not inconsistent with the Separation Agreement and the terms of the Adjusted Award assumed under the Separation Agreement:

4.1 Award of Share Units.

SunCoke Energy, Inc.

Long-Term Performance Enhancement Plan

Page 12 of 18

4.3 Dividend Equivalents. Unless otherwise determined by the Committee, this Section 4.3 shall govern the treatment of Dividend Equivalents. A holder of Share Units will be entitled to receive payment from the Company in an amount equal to each cash dividend (“Dividend Equivalent”) the Company would have paid to such holder had he, on the record date for payment of such dividend, been the holder of record of Shares equal to the number of outstanding Share Units. The Company shall establish a bookkeeping account on behalf of each Participant in which the Dividend Equivalents allocated to such Participant (“Dividend Equivalent Account”) shall be credited. The Dividend Equivalent Account will not bear interest. Vesting and payment of Dividend Equivalents will correspond to the vesting and settlement of the Share Units with respect to which the Dividend Equivalents relate.

4.4 Section 162(m) of the Code. In the event that the Committee conditions the vesting of an Award of Share Units upon the attainment of Performance Goals or the attainment of Performance Goals and the continued service of the applicable Participant, the Committee may, prior to or at the time of grant, designate such an Award as a Qualified Performance-Based Award.

Vesting and payment of any cash dividends will correspond to the vesting of the Restricted Stock with respect to which such dividends relate.

(a) the listing, registration or qualification of the Shares subject or related thereto upon any securities exchange or under any state or Federal law; or

(b) the consent or approval of any government regulatory body; or

(c) an agreement by the recipient of an Award with respect to the disposition of Shares,

is necessary or desirable as a condition of, or in connection with, the granting of such Award or the issue or purchase of Shares thereunder, then such Award may not be consummated in whole or in part unless such listing, registration, qualification, consent, approval or agreement shall have been effected or obtained free of any conditions not acceptable to the Committee.

6.2 Non-Assignability. Awards under the Plan shall not be assignable or transferable by the recipient thereof, except by will or by the laws of descent and distribution, except as otherwise set forth in this Plan or except as otherwise determined by the Committee.

6.3 Right to Terminate Employment; Effect of Disaffiliation. Nothing in the Plan or in any agreement entered into pursuant to the Plan shall confer upon any Participant the right to continue in the employment of the Company, or affect any right which the Company may have to terminate the employment of, or service by, such Participant. If an Affiliate ceases to be an Affiliate as a result of the sale or other disposition by the Company or one of its continuing Affiliates of its ownership interest in the former Affiliate, or otherwise, then individuals who remain employed by such former Affiliate thereafter shall be considered for all purposes under the Plan to have terminated their employment relationship with the Company and its Subsidiaries.

6.4 Non-Uniform Determinations. The Committee’s determinations under the Plan (including without limitation, determinations of the persons to receive Awards, the form, amount and timing of such Awards, the terms and provisions of such Awards, and the agreements evidencing same) need not be uniform and may be made by it selectively among persons who receive, or are eligible to receive, Awards under the Plan, whether or not such persons are similarly situated.

6.5 Rights as a Shareholder. Except as otherwise provided in Section 5.4 with respect to Restricted Stock, the recipient of any Award under the Plan shall have no rights as a shareholder with respect thereto unless and until Shares are issued on behalf of such recipient in “book-entry” form, in the records of the Company’s transfer agent and registrar, or certificates have been issued for such Shares.

6.6 Leaves of Absence. The Committee shall be entitled to make such rules, regulations and determinations as it deems appropriate under the Plan in respect of any leave of absence taken by the recipient of any Award. Without limiting the generality of the foregoing, the Committee shall be entitled to determine (a) whether or not any such leave of absence shall constitute a termination of employment within the meaning of the Plan and (b) the impact, if any, of any such leave of absence on Awards under the Plan theretofore made to any recipient who takes such leaves of absence.

6.7 Newly Eligible Employees. The Committee shall be entitled to make such rules, regulations, determinations and Awards as it deems appropriate in respect of any employee who becomes eligible to participate in the Plan or any portion thereof after the commencement of an Award or incentive period.

6.8 Adjustments.

(a) In the event of a stock dividend, stock split, reverse stock split, share combination, or recapitalization or similar event affecting the capital structure of the Company (each a “Share Change”), the Committee or Board of Directors shall make an equitable and proportionate anti-dilution adjustment. Such mandatory adjustment may include a change in one or more of the following: (i) the aggregate number of Shares reserved for issuance and delivery under Section 2.6(a) of the Plan; (ii) the individual limits under Section 2.6(b) of the Plan; (iii) the number of Shares or other securities subject to outstanding Awards under the Plan; (iv) the exercise price of outstanding Options; and (v) other similar matters.

(b) In the event of a merger, amalgamation, consolidation, acquisition of property or shares, separation, spinoff, other distribution of stock or property (including any extraordinary cash or stock dividend), reorganization, stock rights offering, liquidation, Disaffiliation, or similar event affecting the Company or any of its Subsidiaries that is not a Share Change (each, a “Corporate Transaction”), the Committee or the Board of Directors may in its discretion make such substitutions or adjustments as it deems appropriate and equitable to (i) the aggregate number and kind of Shares or other securities reserved for issuance and delivery under Section 2.6(a) of the Plan; (ii) the individual limits under Section 2.6(b) of the Plan; (iii) the number and kind of Shares or other securities subject to outstanding Awards under the Plan; (iv) the exercise price of outstanding Options; and (v) other similar matters, and such adjustments may include, without limitation, (A) the cancellation of outstanding Awards granted under the Plan in exchange for payments of cash, property or a combination thereof having an aggregate value equal to the value of such Awards, as determined by the Committee or the Board of Directors in its sole discretion (it being understood that in the case of a Corporate Transaction with respect to which holders of Common Stock receive consideration other than publicly traded equity securities of the ultimate surviving entity, any such determination by the Committee or the Board of Directors that the value of an Option shall for this purpose be deemed to equal the excess, if any, of the value of the consideration being paid for each Share pursuant to such Corporate Transaction over the exercise price of such Option shall conclusively be deemed valid), (B) the substitution of other property (including, without limitation, cash or other securities of the Company and securities of entities other than the Company) for the Shares subject to outstanding Awards under the Plan, and (C) in connection with any Disaffiliation, arranging for the assumption of Awards granted under the Plan, or replacement of Awards granted under the Plan with new Awards based on other property or other securities (including, without limitation, other securities of the Company and securities of entities other than the Company), by the affected Subsidiary, Affiliate, or division or by the entity that controls such Subsidiary, Affiliate, or division following such Disaffiliation as well as any corresponding adjustments to Awards under the Plan that remain based upon Company securities.

6.9 Change in Control. The Committee may provide in any Award agreement for provisions relating to a Change in Control, including, without limitation, the acceleration of the exercisability of, or the lapse of restrictions or deemed satisfaction of goals with respect to, any outstanding Awards.

6.10 Amendment of the Plan; Amendment of Awards.

(a) The Committee may amend, alter, or discontinue the Plan, but no amendment, alteration or discontinuation shall be made which would materially impair the rights of the Participant with respect to a previously granted Award without such Participant’s consent, except such an amendment made to comply with applicable law, including without limitation Section 409A of the Code, stock exchange rules or accounting rules. In addition, no such amendment shall be made without the approval of the Company’s stockholders to the extent such approval is required by applicable law or the listing standards of the Applicable Exchange.

(b) Subject to Section 3.3, the Committee may unilaterally amend the terms of any Award theretofore granted, but no such amendment shall cause a Qualified Performance-Based Award to cease to qualify for the Section 162(m) Exemption or without the Participant’s consent materially impair the rights of any Participant with respect to an Award, except such an amendment made to cause the Plan or Award to comply with applicable law, stock exchange rules or accounting rules.

6.11 Limitation on Dividend Reinvestment and Dividend Equivalents. Reinvestment of dividends in additional Restricted Stock at the time of any dividend payment, and the payment of Shares with respect to dividends to Participants holding Awards of Restricted Stock Units, shall only be permissible if sufficient Shares are available under Section 2.6 for such reinvestment or payment (taking into account then outstanding Awards).

6.12 Required Taxes. No later than the date as of which an amount first becomes includible in the gross income of a Participant for federal, state, local or foreign income or employment or other tax purposes with respect to any Award under the Plan, such Participant shall pay to the Company, or make arrangements satisfactory to the Company regarding the payment of, any federal, state, local or foreign taxes of any kind required by law to be withheld with respect to such amount. If determined by the Company, withholding obligations may be settled with Shares, including Shares that are part of the Award that gives rise to the withholding requirement. The obligations of the Company under the Plan shall be conditional on such payment or arrangements, and the Company and its Affiliates shall, to the extent permitted by law, have the right to deduct any such taxes from any payment otherwise due to such Participant. The Committee may establish such procedures as it deems appropriate, including making irrevocable elections, for the settlement of withholding obligations with Shares.

6.13 Section 409A of the Code. It is the intention of the Company that no Award shall be “deferred compensation” subject to Section 409A of the Code, unless and to the extent that the Committee specifically determines otherwise as provided in the immediately following sentence, and the Plan and the terms and conditions of all Awards shall be interpreted accordingly. The terms and conditions governing any Awards that the Committee determines will be subject to Section 409A of the Code, including any rules for elective or mandatory deferral of the delivery of cash or Shares pursuant thereto and any rules regarding treatment of

such Awards in the event of a Change in Control, shall be set forth in the applicable Award Agreement, and shall comply in all respects with Section 409A of the Code. Notwithstanding any other provision of the Plan to the contrary, with respect to any Award that constitutes a “nonqualified deferred compensation plan” subject to Section 409A of the Code, any payments (whether in cash, Shares or other property) to be made with respect to the Award upon the Participant’s termination of employment shall be delayed until the first day of the seventh month following the Participant’s termination of employment if the Participant is a “specified employee” within the meaning of Section 409A of the Code.

6.14 Governing Law. This Plan shall be construed in accordance with and governed by the laws of the State of Delaware.
