WHEREAS, Executive serves as the Senior Vice President, Commodity Risk Management of the Company pursuant to an employment agreement dated as of March 15, 2010 (the “Employment Agreement”); and

WHEREAS, Executive will separate from employment with the Company effective as of the Termination Date.

NOW, THEREFORE, for and in consideration of the mutual promises, covenants and obligations contained herein and in satisfaction of the Company’s obligations to Executive, the Company and Executive agree as follows:

ARTICLE I:           TERMINATION.

Section 1.1             Termination of Employment.  Executive’s employment as the Senior Vice President, Commodity Risk Management of the Company shall terminate effective as of the Termination Date.

Section 1.2             Other Positions.  In connection with the termination of Executive’s employment pursuant to Section 1.1, Executive hereby agrees to resign from any and all other positions he holds with the Company and its affiliates, whether as an officer, director, employee or otherwise and following the Termination Date, Executive shall have no authority to act on behalf of the Company or any of its affiliates.

ARTICLE II:          TERMINATION PAYMENTS AND BENEFITS; EFFECT OF TERMINATION

Section 2.1             Compensation Upon Termination Date.  As soon as practicable, but in no event later than 30 days following the Termination Date, the Company shall (a) pay Executive any accrued but unpaid base salary earned through the Termination Date, (b) reimburse Executive for any business expenses incurred through, but not reimbursed prior to, the Termination Date, (c) pay to Executive a payment for his accrued but unused vacation through the Termination Date, and (d) pay or provide to Executive such vested accrued benefits, if any, as to which Executive may be entitled under the Company’s employee benefit plans and programs applicable to Executive as of the Termination Date (other than any severance pay plan), which shall be paid or provided in accordance with the terms of the applicable plan or program.

Section 2.2             Termination Payment.  Subject to and in consideration of Executive’s execution and non-revocation of the release set forth on Annex A attached hereto, the Company agrees to pay or provide Executive with the payment and benefits set forth in paragraphs 2.2(a) and 2.2(b) below.

(a)           A lump sum payment of $700,000 (the “Termination Payment”) on the date that is thirty (30) days following the Termination Date, subject to the execution (and non-revocation) of the release (the “Payment Date”).

(b)           The Company shall pay the costs of continued group medical, dental, and vision insurance coverage for Executive and his dependents under the plans and programs in which Executive participated immediately prior to the Termination Date, or materially equivalent plans and programs maintained by the Company in replacement thereof, for a period of twelve (12) months following the Termination Date (the “Coverage Period”); provided, that in the event the medical, dental, and vision plans under which Executive and his dependents were receiving benefits immediately prior to the Termination Date, or any applicable replacement plan or program, is not fully-insured, then in lieu of the foregoing, if Executive timely elects coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”) and timely pays the monthly premiums for such COBRA coverage, then the Company shall reimburse Executive during the Coverage Period for the amount of such monthly premium that is in excess of the active employee rate (excluding, for purposes of calculating cost, an employee’s ability to pay premiums with pre-tax dollars), on a tax grossed-up basis to the extent such monthly premium is taxable to Executive, payable on the first Company payroll date in each month following the Termination Date (collectively, the “COBRA Benefit”).

(c)           Executive has previously vested in 26,666 Restricted Stock Units, which shall be settled on the date that is six (6) months following the Termination Date; provided, that, notwithstanding the foregoing, delivery of shares of Common Stock in respect of settlement of such Restricted Stock Units shall be contingent upon Executive’s delivery of a certified check to the Company for the full amount of the employment and income tax withholding obligation arising in connection with such settlement.  Any unvested Restricted Stock Units held by Executive as of the Termination Date shall be forfeited.

(d)           Executive has previously vested in 42,750 Options, which shall remain exercisable until the Payment Date, and shall terminate as of such date to the extent not exercised.  All unvested Options held by Executive shall terminate as of the Termination Date.

(e)           The Company will deliver to Executive 22,596 shares of Common Stock on the Payment Date.

(f)            All hybrid equity units held by Executive, whether vested or unvested, shall terminate as of the Termination Date.

2

(g)           Executive acknowledges and agrees that he is not otherwise entitled to the payments and benefits other than as set forth above in this Section 2.2 and that such payments and benefits constitute fair and sufficient consideration for Executive’s execution, delivery to the Company and non-revocation of the release set forth on Annex A.

Section 2.3             Withholding of Taxes.  The Company may withhold from any benefits or compensation payable under this Agreement all federal, state, city or other taxes as may be required pursuant to any law or governmental regulation or ruling. Any withholding amounts due to be withheld under this Agreement shall be withheld from the Termination Payment.

Section 2.4             Benefit Eligibility.  As of the Termination Date (or any earlier termination of employment), Executive shall cease to be eligible to participate in any of the Company’s employee benefit plans for the benefit of employees and officers, other than his right to elect continuation coverage under any group health plan.

Section 2.5             No Other Payments.  Executive acknowledges and agrees that the Company does not owe Executive any wages; compensation; bonuses; deferred compensation; awards; sick pay; personal leave pay; notice pay; severance pay; vacation pay; expense reimbursement; payments, rights, or continued coverage under any medical or other benefit policy or plan or qualified or non-qualified retirement plan; or any other forms of remuneration of any kind or nature, except as provided in this Agreement.

Section 2.6             Nondisclosure of Agreement; Noninterference.  Executive acknowledges and agrees that the existence and terms of this Agreement are highly confidential and could result in material harm to the Company if made known to third parties.  Accordingly, Executive acknowledges and agrees that the existence and terms of this Agreement may only be disclosed by Executive to his spouse and legal and financial advisers who will be informed that they are to keep any and all information regarding this agreement strictly confidential.  Executive further acknowledges and agrees that he shall have no contact or discussions with employees of the Company involving any human resources matters (including, but not limited to, prior, current and future compensation arrangements), which are highly confidential and sensitive and could result in material harm to the Company if made discussed.  In the event that Executive violates any of the provisions of this Section 2.6, Executive shall be required to promptly return the Termination Payment to the Company.  Notwithstanding the foregoing, the parties acknowledge that the Company may be required to disclose certain aspects of this Agreement in accordance with applicable disclosure compliance procedures.

Section 2.7             Survival of  Employment Agreement Provisions.  Sections 10 and 11 of the Employment Agreement shall continue to apply following the Termination Date; provided, that, notwithstanding the foregoing, the provisions of Section 11(a)(iii), Section 11(a)(iv) and Section 11(c) of the Employment Agreement shall not apply to Executive following the Termination Date.

Executive will not be entitled to recover and Executive agrees to waive any monetary benefits or other recovery in connection with any such charge or proceeding, without regard to who has brought such charge or proceeding.

8.                                       Litigation And Regulatory Cooperation.  Executive shall (a) reasonably cooperate with the Company and/or Related Parties in the defense or prosecution of any claims or actions now in existence or that may be brought in the future against or on behalf of the Company and/or
