EXHIBIT 10.13

EMPLOYMENT AGREEMENT

     THIS EMPLOYMENT AGREEMENT (the "Agreement") is entered into as of August 1, 2002, by and between Charles O. Dunn ("Executive") and Mississippi Chemical Corporation ("Company"), a corporation organized and existing under the laws of the State of Mississippi, and is intended to amend, restate and supersede, in its entirety, that certain Severance Agreement between Mississippi Chemical Corporation and Executive, initially effective as of July 29, 1996.

     The Company has determined that Executive is a key manager of the Company and that Executive's performance, the Company's ability to retain Executive in its employment, and Executive's impartial assistance to the Company's Board of Directors in the evaluation of any potential merger, acquisition, sales, financing or other transactions will be significantly enhanced by this Agreement.
     1.     Defined Terms.

             Unless otherwise indicated, capitalized terms used in this Agreement shall have the meanings set forth herein or in Schedule A attached hereto and incorporated herein.

     2.     Employment Terms.

             a.     Position.  For the duration of the Employment Term, the Company agrees to employ Executive, and Executive agrees to remain in the employ of the Company, as its President and Chief Executive Officer or in such other capacity or capacities as are, from time to time, mutually agreed upon by Executive and the Company, all subject to the terms and conditions set forth herein. Notwithstanding the foregoing, the provisions of this Agreement relating to a Change of Control shall remain in effect for as long as Executive is employed by Company and shall, if in effect on the date of a Change of Control, remain in effect for at least three (3) years following such Change of Control, and such additional time as may be necessary to give effect to the terms of this Agreement.

            b.     Duties and Reporting.  Executive's duties and responsibilities will be those assigned to him, from time to time, by the Company and, unless otherwise mutually agreed between the Company and Executive, will include such duties as are of the type and nature normally assigned to executives in a similar position in a corporation of the size, type and stature of the Company.

            c.     Full Attention.  During the Employment Term, Executive will devote his full time, attention and energies to the business of the Company and will not, without disclosure to the chairman of the Board of Directors and to the chairman of the Compensation Committee of the Board of Directors, be engaged (whether or not during normal business hours) in any other business or professional activity, whether or not such activities are pursued for gain, profit or other pecuniary advantage. Notwithstanding the foregoing and so long as Executive's ability to devote his full time, attention and energies to the business of the Company is not impaired, Executive will not be prevented from (i) engaging in any civic or charitable activity for which Executive receives no compensation or other pecuniary advantage, (ii) investing his personal assets and participating in businesses which do not compete with the Company, or (iii) purchasing securities in any corporation whose securities are regularly traded, *provided* that such purchases will not result in Executive's owning beneficially at any time five percent (5%) or more of the equity securities of any corporation engaged in a business competitive with that of the Company.

            d.     Base Salary.  The Company shall pay Executive an annual base salary equal to his annual base salary in effect as of the Effective Date, or as subsequently increased, from time to time, by the Company in its sole discretion (Executive's "Base Salary"). Executive's Base Salary may not be reduced at any time during the Employment Term unless such reduction is part of a reduction in pay uniformly applicable to all similarly situated employees of the Company. Executive's Base Salary will be prorated and paid in equal installments and will be reviewed by the Company no less often than annually.

            e.     Benefits.  During the Employment Term, Executive shall participate in such benefit plans, policies, and programs as may be maintained from time to time by the Company and for which Executive is eligible, whether the same are for the benefit of all employees or for the benefit of employees similarly situated to Executive, including, without limitation, any profit sharing, bonus, life insurance, defined contribution and defined benefit pension plans, and group medical, dental and other welfare benefit plans. Any such benefits and Executive's eligibility therefor shall be determined in accordance with the specific terms and conditions of the documents evidencing any such benefit plans, policies, and programs, as adopted or amended by the Company from time to time.

             f.     Reimbursement.  The Company will reimburse Executive for such reasonable and necessary expenses as are incurred in carrying out his duties hereunder, consistent with the Company's then current reimbursement policy. The Company's obligation to reimburse Executive is contingent upon the presentment by Executive of documentation required by the Company.

     3.     Termination Payments to Executive.

            Subject to the terms of Sections 4, 5 and 6 below, in the event of the termination of Executive's employment with the Company during the Employment Term (as it may have been) extended or following a Change of Control, Executive will be paid the amounts and benefits set forth below except as provided elsewhere in this Section 3:

            a.     Executive's Death or Disability.  If Executive dies or becomes Disabled during the Employment Term, this Agreement and Executive's employment hereunder shall immediately terminate and the Company's obligations hereunder shall automatically cease. In such event, the Company will pay to Executive (or his estate) Executive's Base Salary accrued but not yet paid as of his Termination Date, Executive's vacation accrued but not yet used as of the date of his death or Disability, and such other amounts, benefits and assistance as the Company then provides to other employees similarly situated to Executive (or their families) when such employees die or become Disabled while in the employ of the Company. Payment under this Section 3.a will be made in the form of one or more lump sums as soon as practicable after Executive's death or becoming Disabled or as and when such amounts are ascertainable. 

            b.     Executive's Termination for Cause.  This Agreement and Executive's employment hereunder may be terminated by the Company at any time for Cause. In such event, the Company shall pay to Executive his Base Salary accrued but not yet paid as of his Termination Date and Executive's vacation accrued but not yet used as of his Termination Date, such payment being in a lump sum as soon as practicable after Executive's Termination Date. No additional amount will be paid to Executive except as may be required by law or by the terms of any pension or other benefit plan in which Executive is a participant.

                    (v)     an amount equal to Executive's Target Bonus, if any, multiplied by a fraction, the numerator of which shall be the number of days Executive was employed by the Company in the fiscal year in which the Termination Date occurs and the denominator of which shall be three hundred sixty-five (365), such amount to be payable in the form of a lump sum not later than three (3) business days after such amount is ascertainable;

Until the earlier of the third anniversary of the Termination Date or the date on which Executive becomes covered under another group medical plan with no preexisting condition exclusion effective as to the Executive or his spouse or dependents, the Company will allow Executive and his spouse and dependents to purchase medical and/or dental coverage under Company's group medical plan's and dental COBRA continuation coverage procedures (without regard to whether the Executive and his spouse and dependents would be entitled to such continuation coverage for such period of time by law or under such group medical or dental plan); *provided, however*, that if Executive becomes employed by a new employer which maintains a medical plan (or dental plan) that either (i) does not cover Executive with respect to a preexisting condition which was covered under the Company's group medical plan, or (ii) does not cover Executive for a designated waiting period, Executive's coverage under the Company's group medical plan (or dental plan) shall continue (but shall be limited in the event of non-coverage due to a preexisting condition, to the existence of the preexisting condition itself) until the earlier of the end of the applicable period of non-coverage under the new employer's plan or the third anniversary of the Termination Date.

            g.     Change of Control, Other Agreements.  All Change-of-Control provisions applicable to Executive and contained in any plan, program, agreement or arrangement maintained on or after the Effective Date by the Company (including, but not limited to, any stock option, restricted stock, deferred compensation, supplemental benefit or pension plan) shall remain in effect for such period after the date of a Change of Control as is necessary to carry out such provisions and provide the benefits payable thereunder, and may not be altered in a manner which adversely affects Executive without Executive's prior written approval.

            h.     Consideration.  Executive acknowledges that all or a portion of any amount payable to him pursuant to Sections 3.c(iii), 3.c(v), 3.d(iii), 3.d(v), 3.e(iii) and 3.e(v) hereof (after any reduction under Section 4) is in addition to the amount required by law or otherwise due or payable to Executive under any severance plan of the Company, and that the payment of such additional amount is intended to and shall constitute adequate consideration for Executive's obligations set forth in Sections 5 and 13 hereof. Executive further acknowledges that all or a portion of any amount payable to him pursuant to Sections 3.c(iv), 3.c(vi), 3.c(vii), 3.c(viii), 3.d(iv), 3.d(vi), 3.d(vii), 3.d(viii), 3.e(iv), 3.e(vi), 3.e(vii) and 3.e(viii), hereof (after any reduction under Section 4) is in addition to the amount required by law or otherwise due or payable to Executive under any severance plan of the Company, and that the payment of such additional amount is intended to and shall constitute adequate consideration for Executive's execution and delivery of the Release. Any payment pursuant to Sections 3.c(iv), 3.c(vi), 3.c(vii), 3.c(viii), 3.d(iv), 3.d(vi), 3.d(vii), 3.d(viii), 3.e(iv), 3.e(vi), 3.e(vii) and 3.e(viii) hereof (after any reduction under Section 4) is expressly conditioned on Executive's execution and delivery (and non-revocation) of such Release. 

     4.     Payment Limitation.

             a.     Notwithstanding Section 3 above or any other provision of this Agreement or any other agreement, arrangement or plan, in no event shall the Company pay or be obligated to pay the Executive an amount which would be an Excess Parachute Payment except as provided in Section 4.f. below. For purposes of this Agreement, the term "Excess Parachute Payment" shall mean any payment or any portion thereof which would be an "excess parachute payment" within the meaning of Section 280G(b)(1) of the Internal Revenue Code of 1986, as amended ("Code"), and would result in the imposition of an excise tax under Section 4999 of the Code, in the opinion of tax counsel selected by the Company, which counsel is reasonably acceptable to the Executive ("Tax Counsel").  In the event it is determined that an Excess Parachute Payment would result if the full payments provided in Section 3 above were made (when added to any other payments or benefits contingent on a change of control under any other agreement, arrangement or plan), the payments due under Sections 3.c(iii) through 3.c(vi), Sections 3.d(iii) through 3.d(vi) or Sections 3.e(iii) through 3.e(vi), whichever are applicable, shall be reduced to the minimum extent necessary to prevent an Excess Parachute Payment; then, if necessary to prevent an Excess Parachute Payment, benefits or payments under any other plan, agreement or arrangement shall be reduced, and then benefits payable under Section 3.f.  If it is established pursuant to a final determination of a court or an Internal Revenue Service administrative appeals proceeding that, notwithstanding the good faith of the Executive and the Company in applying the terms of this Section 4.a, a payment (or portion thereof) made is an Excess Parachute Payment, then, the Company shall pay to the Executive an additional amount in cash (a "Gross-Up Payment") equal to the amount necessary to cause the amount of the aggregate after-tax compensation and benefits received by the Executive hereunder (after payment of the excise tax under Section 4999 of the Code with respect to any Excess Parachute Payment, and any state and federal income taxes with respect to the Gross-Up Payment) to be equal to the aggregate after-tax compensation and benefits he would have received as if Sections 280G and 4999 of the Code had not been enacted.

             b.     Subject to the provisions of Section 4.c, the amount of any Gross-Up Payment and the assumptions to be utilized in arriving at such amount, shall be determined by a nationally recognized certified public accounting firm designated by the Company (the "Accounting Firm"). All fees and expenses of the Accounting Firm shall be borne solely by the Company. Any Gross-Up Payment, as determined pursuant to Section 4.a, shall be paid by the Company to the Executive within five (5) days after the receipt of the Accounting Firm's determination. Any determination by the Accounting Firm shall be binding upon the Company and Executive.

             c.     Executive shall notify the Company in writing of any claim by the Internal Revenue Service that, if successful, would require the payment by Company of a Gross-Up Payment. Such notification shall be given no later than ten (10) business days after Executive is informed in writing of such claim and shall apprise the Company of the nature of the claim and the date of requested payment. Executive shall not pay the claim prior to the expiration of the thirty (30) day period following the date on which it gives notice to the Company. If the Company notifies Executive in writing prior to the expiration of the period that it desires to contest such claim, Executive shall:

                  (i)     give the Company any information reasonably requested by the Company relating to such claim;

                  (ii)     take such action in connection with contesting such claim as the Company shall reasonably request in writing from time to time, including, without limitation, accepting legal representation with respect to such claim by an attorney selected by the Company and reasonably acceptable to Executive;

                  (iii)     cooperate with the Company in good faith in order to effectively contest such claim; and

                  (iv)     permit the Company to participate in any proceedings relating to such claim.

                  Without limitation on the foregoing provisions of this Section 4.c, the Company shall control all proceedings taken in connection with such contest and, at its sole option, may pursue or forego any and all administrative appeals, proceedings, hearings and conferences with the taxing authority in respect of such claim and may, at its sole option, either direct Executive to pay the tax claimed and sue for a refund or contest the claim in any permissible manner, and Executive agrees to prosecute such contest to a determination before any administration tribunal, in a court of initial jurisdiction and in one or more appellate courts, as the Company shall determine; *provided, however, that the Company shall bear and pay directly all costs and expenses (including additional interest and penalties) incurred in connection with such contest and shall indemnify and hold Executive harmless, on an after-tax basis, for any Excise Tax or income tax (including interest and penalties with respect thereto) imposed as a result of the contest;*provided, further, that if the Company directs Executive to pay any claim and sue for a refund, the Company shall advance the amount of the payment to Executive, on an interest-free basis, and shall indemnify and hold Executive harmless, on an after-tax basis, from any Excise Tax or income tax (including interest or penalties with respect thereto) imposed with respect to the advance or with respect to any imputed income with respect to the advance.
            d.     In the event that the Company exhausts its remedies pursuant to Section 4.c and Executive thereafter is required to make a payment of any Excise Tax, the Accounting Firm shall determine the amount of the Gross-Up Payment required and such payment shall be promptly paid by the Company to or for the benefit of Executive.

            e.     If, after the receipt of Executive of an amount advanced by the Company pursuant to Section 4.c, Executive becomes entitled to receive any refund with respect to such claim, Executive shall promptly after receiving such refund pay to the Company the amount of such refund (together with any interest paid or credited thereon after taxes applicable thereto). If, after the receipt by Executive of an amount advanced by the Company pursuant to Section 4.c, a determination is made that Executive shall not be entitled to any refund with respect to such claim and the Company does not notify Executive in writing of its intent to contest such denial of refund prior to the expiration of thirty (30) days after such determination, then such advance shall be forgiven and shall not be required to be repaid and the amount of such advance shall offset, to the extent thereof, the amount of Gross-Up Payment required to be paid.

             f.     Notwithstanding the foregoing, the limitation set forth in Section 4.a shall not apply to a Participant if in the opinion of Tax Counsel or the Accounting Firm (i) the total amounts payable to the Participant hereunder and under any other agreement, arrangement or plan as a result of a Change of Control (calculated without regard to the limitation of Section 4.a), reduced by the amount of excise tax imposed on the Executive under Code Section 4999 with respect to all such amounts and reduced by the state and federal income taxes on amounts paid in excess of the limitation set forth in Section 4.a, would exceed (ii) such total amounts payable after application of the limitation of Section 4.a.  No Gross-Up Payment shall be made in such case.

     5.     Executive Covenants
             a.     Return of Property.  On or as soon as practicable after the Termination Date, Executive shall promptly return to the Company all of the property of the Company in his possession or under his control, wherever located, including, without limitation, automobiles, equipment, computers, fax machines, portable telephones, printers, software, credit cards, manuals, customer lists, financial data, letters, notes, notebooks, reports and copies of any of the above and any Confidential Information in any form.

             b.     Confidential Information and Non*-*Solicitation.  Executive shall not, without the consent of the Company, disclose to any person, or use to the disadvantage of the Company, any non-public information relating to the Company, including without limitation, any information relating to business plans, marketing plans, sales plans, technical information, methods of doing business, customers, customer contracts, suppliers, costs, prices or Executives of the Company ("Confidential Information"), *provided, that nothing contained in this Section 5.b shall prevent Executive from being employed by a competitor of the Company or utilizing Executive's general skills, experience, and knowledge, including those developed while employed by the Company. For one year following Employee's Termination Date, Executive shall not, without the express consent of the Company, solicit or perform services, as an employee, independent contractor, or otherwise, for any person (including affiliates or subsidiaries of that person) that is or was a customer or prospect of the Company during the two (2) year period prior to the Termination Date if Executive solicited business from or performed services for that customer or prospect while employed by Company. For one year following Executive's Termination Date, Executive shall not recruit, hire or help anyone recruit or hire anyone who is then an Executive of the Company or of any of its customers for and/or from whom Executive, within the two (2) year period prior to the Termination Date, performed services or solicited business. If Executive breaches any of these covenants, he shall forfeit all rights under this Agreement and shall be obligated to return to the Company any amounts previously received hereunder (other than payment under Sections 3.a, 3.b, 3.c(i), 3.c(ii), 3.d(i), 3.d(ii), 3.e(i), and 3.e(ii), whichever are applicable).
             c.     Business Reputation.  Executive agrees that during the Employment Term and at all times thereafter, he shall refrain from performing any act, engaging in any conduct or course of action or making or publishing an adverse, untrue or misleading statement which has or may reasonably be expected to have the effect of demeaning the name or business reputation of the Company or which adversely affects (or may reasonably be expected to adversely affect) the best interests (economic or otherwise) of the Company.  Notwithstanding the foregoing, Executive may make truthful statements to any governmental entity or as required by law.

            d.     Release.  In consideration for the protection and benefits provided for under this Agreement, Executive hereby agrees to execute a release similar to the form of Schedule B and acceptable to the Company. Payment of any amount under Sections 3.c(iv), 3.c(vi), 3.c(vii), 3.c(viii), 3.d(iv), 3.d(vi), 3.d(vii), 3.d(viii), 3.e(iv), 3.e(vi), 3.e(vii) and 3.e(viii) hereof (after any reduction under Section 4) is expressly conditioned on Executive's execution and delivery (and non-revocation) of the Release. In the event Employee fails or refuses to execute, or revokes, the Release, the amount payable to Employee under Section 3 shall be reduced (after any reduction under Section 4) by the amount that would have been paid under Sections 3.c(iv), 3.c(vi), 3.c(vii), 3.c(viii), 3.d(iv), 3.d(vi), 3.d(vii), 3.d(viii), 3.e(iv), 3.e(vi), 3.e(vii) and 3.e(viii), hereof had the Release been executed, delivered and not revoked.

            e.     Company's Remedies.  In the event of a breach or threatened breach by Executive of the provisions of Sections 5.a, 5.b, 5.c or 5.f hereof, Executive agrees that the Company will be entitled to a temporary restraining order or a preliminary injunction (without the necessity of posting bond in connection therewith) and that any additional payments or benefits due to Executive or his dependents under Section 3 hereof shall be canceled and forfeited. Nothing herein shall be construed as prohibiting the Company from pursuing any other remedy available to it for such breach or threatened breach, including the recovery of damages from Executive.
