Unless otherwise provided in this Article III, the Performance Units shall vest on the fifteenth (15^th) day of each calendar month, in equal monthly increments, during the period beginning on the Grant Date and ending on December 31, 2016 (the “Performance Cycle”).

Section 3.2 -     Effect of Certain Events. Notwithstanding the foregoing Section 3.1, during the Performance Cycle:

(a)upon the Grantee’s Termination of Employment either (i) within twelve months following a Change of Control, provided such Termination of Employment is by the Company without Cause or by the Grantee for Good Reason; or (ii) on account of the Grantee’s death or Disability, all of the Performance Units shall become immediately vested and the Grantee shall become entitled to the Incentive Amount calculated and payable pursuant to Article IV hereof with respect to the Performance Units that are vested as of the date of Termination of Employment;

(b)upon the earliest of: (i) a Termination of Employment on account of Retirement, or (ii) except as provided in Section 3.2(a) above, a Termination of Employment by the Company without Cause, or by the Grantee for Good Reason, the Performance Units shall cease to vest, any and all Performance Units that remain unvested on the date of such Termination of Employment shall terminate immediately, and the Grantee shall become entitled to the Incentive Amount calculated and payable pursuant to Article IV hereof with respect to the Performance Units that are vested as of the date of such Termination of Employment; and

(c)upon the earlier of (i) a Termination of Employment by the Company for Cause, and (ii) a Termination of Employment by the Grantee without Good Reason, all

Performance Units (whether or not they are vested) shall terminate and the Grantee shall not be entitled to any Incentive Amount hereunder.

Section 4.1 -     Calculation of Incentive Amount. The Incentive Amount, if any, payable to the Grantee hereunder shall be calculated as of the Determination Date in accordance with this Section 4.1.

(a)Pre-Change of Control. The Incentive Amount shall equal the result of the following formula:

(0.5 x A x B x C) + (0.5 x A x B x D);

where

“A” = the number of Performance Units that are vested as of the Determination Date pursuant to Article III hereof;

“B” = the FMV per Share as of the Determination Date;

“C” = the applicable composite total shareholder return payout percentage determined under Section 4.2 below (the “Composite TSR Percentage”) as of the Determination Date; and

“D” = the applicable ROMA payout percentage determined under Section 4.3 below (the “ROMA Percentage”) as of the Determination Date.

(b)Post-Change of Control that is not a Trade Ceasing Transaction. Notwithstanding Section 4.1(a) hereof, if a Change of Control that is NOT a Trade Ceasing Transaction occurs, then on the Determination Date, the Incentive Amount shall be equal to the sum of the amounts determined pursuant to clauses (i) and (ii) immediately below:

(i)Pre-Transaction Amount. The pre-transaction amount shall equal the result of the following formula:

(0.5 x A x B x C) + (0.5 x A x B x D)

Where:

“A” = the number of Performance Units that are vested as of the date of the Change of Control;

“B” = the FMV per Share as of the date of the Change of Control;

“C” = the Composite TSR Percentage as of the date of the Change of Control; and

“D” = the ROMA percentage as of the date of the Change of Control.

(ii)Post-Transaction Amount. The post-transaction amount shall equal the result of the following formula:

(0.5 x E x F x G) + (0.5 x E x F x H)

Where:

“E” = the number of Performance Units that became vested after the date of the Change of Control through the Determination Date;

“F” = the FMV per Share as of the date of the Determination Date;

“G” = the Composite TSR Percentage as of the Determination Date; and

“H” = 100%.

An example of how the Incentive Amount is intended to be determined if the Determination Date is after a Change of Control that is not a Trade Ceasing Transaction is attached as Exhibit A.

(c)Post-Trade Ceasing Transaction. Notwithstanding Section 4.1(a) hereof, if a Change of Control that is ALSO a Trade Ceasing Transaction occurs, then on the Determination Date, the Incentive Amount shall be equal to the sum of the amounts determined pursuant to clauses (i) and (ii) immediately below:

(i)Pre-Transaction Amount. The pre-transaction amount shall equal the result of the following formula:

(0.5 x A x B x C) + (0.5 x A x B x D)

Where:

“A” = the number of Performance Units that are vested as of the date of the Trade Ceasing Transaction;

“B” = the FMV per Share as of the date of the Trade Ceasing Transaction;

“C” = the Composite TSR Percentage as of the date of the Trade Ceasing Transaction; and

“D” = the ROMA percentage as of the date of the Trade Ceasing Transaction.

(ii)Post-Transaction Amount. The post-transaction amount shall equal the result of the following formula:

(0.5 x E x F x G) + (0.5 x E x F x H)

Where:

“E” = the number of Performance Units that became vested after the date of the Trade Ceasing Transaction through the Determination Date;

“F” = the FMV per Share as of the date of the date of the Trade Ceasing Transaction;

“G” = 100%; and

“H” = 100%.

An example of how the Incentive Amount is intended to be determined if the Determination Date is after a Trade Ceasing Transaction is attached as Exhibit B.

(d)Multiple Transactions. In the event that multiple Change of Control transactions occur, the Committee shall equitably determine how the Incentive Amount shall be calculated based on the principles set forth in Sections 4.1(b) and 4.1(c) hereof.

Section 4.2 -     Composite TSR Percentage. The Composite TSR Percentage equals the sum of the weighted payout percentages derived under paragraphs (a) and (b) below as of the Determination Date.

(a)Cumulative TSR - Peer Group Weighted Payout Percentage. The Cumulative TSR - Peer Group measure represents the Company’s average total shareholder return (based on the average of the closing prices of the shares of Common Stock for the four (4) weeks immediately preceding the Determination Date compared to the average of the closing prices of the shares of Common Stock for the four (4) weeks immediately following the Grant Date), expressed as a percentile ranking in an industry peer group (which peer group shall include Alpha Natural Resources, Inc.; Arch Coal Inc.; Cloud Peak Energy, Inc.; Consol Energy, Inc.; Market Vectors Coal ETF (KOL); and Walter Energy) that corresponds with a specified payout percentage.

The table below is used to determine the applicable payout percentage, which is then multiplied by 50% to determine the Cumulative TSR - Peer Group weighted payout percentage for purposes of the Composite TSR Percentage.

Notwithstanding the foregoing, if the Company’s average total shareholder return as of the Determination Date (based on the average of the closing prices of the shares of Common Stock for the four (4) weeks immediately preceding the Determination Date compared to the average of the closing prices of the shares of Common Stock for the four (4) weeks immediately following the Grant Date) is negative, the following shall apply:

(i)If the Company’s total shareholder return percentile ranking is at or above the 50th percentile of the peer group, then the applicable payout percentage used to determine the Cumulative TSR - Peer Group weighted payout percentage for purposes of the Composite TSR Percentage shall be 100%.

(ii)If the Company’s total shareholder return percentile ranking is below the 50th percentile of the peer group, then the Cumulative TSR - Peer Group weighted payout percentage shall be 0%.

(b)Cumulative TSR - S&P 500 Index Weighted Payout Percentage. The Cumulative TSR - S&P 500 Index measure represents the Company’s average total shareholder return (based on the average of the closing prices of the shares of Common Stock for the four (4) weeks immediately preceding the Determination Date compared to the average of the closing prices of the shares of Common Stock for the four (4) weeks immediately following the Grant Date), expressed as a percentile ranking in the Standard & Poor’s 500 Index that corresponds with a specified payout percentage.

The table below is used to determine the applicable payout percentage, which is then multiplied by 50% to determine the Cumulative TSR - S&P 500 Index weighted payout percentage for purposes of the Composite TSR Percentage.

________________________

Notwithstanding the foregoing, if the Company’s average total shareholder return as of the Determination Date (based on the average of the closing prices of the shares of Common Stock for the four (4) weeks immediately preceding the Determination Date compared to the average of the closing prices of the shares of Common Stock for the four (4) weeks immediately following the Grant Date) is negative, the following shall apply:

(i)If the Company’s total shareholder return percentile ranking is at or above the 50th percentile of the Standard & Poor’s 500 Index, then the applicable payout percentage used to determine the Cumulative TSR - S&P 500 Index weighted payout percentage for purposes of the Composite TSR Percentage shall be 100%.

(ii)If the Company’s total shareholder return percentile ranking is below the 50th percentile of the Standard & Poor’s 500 Index, then the Cumulative TSR - S&P 500 Index weighted payout percentage shall be 0%.

(c)For purposes of this Section 4.2, references to the S&P 500 Index shall be deemed to be references to such index, but in all cases excluding the financial services companies that would otherwise be included in such index.

Section 4.3 -     ROMA Percentage. The ROMA Percentage equals the payout percentage derived pursuant to this Section 4.3 as of the Determination Date. The ROMA Percentage measure represents the Company’s aggregate Return on Mining Assets, expressed as a percentage that corresponds with a specified payout percentage. The table below is used to determine the applicable payout percentage.

Section 4.4 -     Form and Time of Payment.

(a)General. Subject to Sections 4.4(b) and 4.5 hereof, the Incentive Amount shall be paid to the Grantee in Common Stock (except as otherwise provided below in this Section 4.4) as soon as administratively feasible but not later than the ninetieth (90th) day following the Determination Date. The number of shares of Common Stock to be distributed to the Grantee shall equal the quotient of (i) the Incentive Amount, divided by (ii) the Fair Market Value of one share of Common Stock on the payment date. Notwithstanding the foregoing, following a Trade Ceasing Transaction, the Incentive Amount shall be paid to the Grantee in cash as soon as administratively feasible but not later than the ninetieth (90th) day following the Determination Date.

(b)Specified Employee. If the Determination Date is triggered by a Termination of Employment other than due to death and at the time of such Termination of Employment the Grantee is a “specified employee” (as such term is defined in Section 409A, but generally meaning one of the Company’s key employees within the meaning of Code Section 416(i)), the Incentive Amount shall be paid to the Grantee on the first day of the seventh month after the Determination Date.

Section 4.5 -     Conditions to Issuance of Stock Certificates. If the Incentive Amount is to be distributed in shares of Common Stock as provided in Section 4.4 hereof and the Committee reasonably anticipates, in accordance with Treasury Regulation Section 1.409A-2(b)(7)(ii)), that issuing Common Stock within the 90-day period following the Determination Date will violate federal securities laws or other applicable laws, the Company may delay issuing such Common Stock, provided that the Company issues such Common Stock on the earliest date on which the Committee reasonably anticipates that such issuance will not violate federal securities laws or other applicable laws.

Section 4.6 -     Stockholder Rights.

No member of the Committee shall be personally liable for any action, determination or interpretation made in good faith with respect to the Plan or the Performance Units. In its absolute discretion, the Board may at any time and from time to time exercise any and all rights and duties of the Committee under the Plan and this Agreement.

Section 5.2 -     Performance Units Not Transferable. Neither the Performance Units nor any interest or right therein or part thereof shall be liable for the debts, contracts or engagements of the Grantee or his or her successors in interest or shall be subject to disposition by transfer, alienation, anticipation, pledge, encumbrance, assignment or any other means whether such disposition is voluntary or involuntary or by operation of law by judgment, levy, attachment, garnishment or any other legal or equitable proceedings (including bankruptcy), and any attempted disposition thereof shall be null and void and of no effect; provided, however, that this Section 5.2 shall not prevent transfers by will or by the applicable laws of descent and distribution.

Section 5.3 -     Withholding. In connection with the payment of the Incentive Amount, unless the Grantee makes alternative arrangements satisfactory to the Company to personally remit required withholding amounts, then as of the date that all or a portion of the Incentive Amount is paid, the Company will withhold a portion of such Incentive Amount with a fair market value as of such date equal to the aggregate amount required by law to be withheld by the Company in connection with such payment for applicable federal, state, local and foreign taxes of any kind.

Any notice to be given under the terms of this Agreement to the Company shall be addressed to the Company in care of its Secretary, and any notice to be given to the Grantee shall be addressed to him or her at the address set forth in the records of the Company. By a notice given pursuant to this Section 5.4, either party may hereafter designate a different address for notices to be given to him, her or it. Any notice which is required to be given to the Grantee shall, if the Grantee is then deceased, be given to the Grantee’s personal representative if such representative has previously informed the Company of his, her or its status and address by written notice under this Section 5.4. Any notice shall be deemed duly given when enclosed in a properly sealed envelope or wrapper addressed as aforesaid, deposited (with postage prepaid) in a post office or branch post office regularly maintained by the United States Postal Service. Notwithstanding the foregoing, any notice required or permitted hereunder from the Company to the Grantee may be made by electronic means, including by electronic mail to the Company-maintained electronic mailbox of the Grantee, and the Grantee hereby consents to receive such notice by electronic delivery. To the extent permitted in an electronically delivered notice described in the previous sentence, the Grantee shall be permitted to respond to such notice or communication by way of a responsive electronic communication, including by electronic mail.

Section 5.9 -     Dispute Resolution. Any dispute or controversy arising under or in connection with this Agreement shall be resolved by arbitration in St. Louis, Missouri. Arbitrators shall be selected, and arbitration shall be conducted, in accordance with the rules of the American Arbitration Association. The Company shall pay or reimburse any legal fees in connection with such arbitration in the event that the Grantee prevails on a material element of his or her claim or defense. Payments or reimbursements of legal fees made under this Section 5.9 that are provided during one calendar year shall not affect the amount of such payments or reimbursements provided during a subsequent calendar year, payments or reimbursements under this Section 5.9 may not be exchanged or substituted for another form of compensation to the Grantee, and any such reimbursement or payment will be paid within sixty (60) days after the Grantee prevails, but in no event later than the last day of the Grantee’s taxable year following the taxable year in which he incurred the expense giving rise to such reimbursement or payment. This Section 5.9 shall remain in effect throughout the Grantee’s employment with the Company and for a period of five (5) years following the Grantee’s Termination of Employment.

Section 5.10 -     Governing Law. The laws of the State of Delaware shall govern the interpretation, validity and performance of the terms of this Agreement regardless of the law that might be applied under principles of conflicts of laws.
