(A)                              The Participant’s Pension Plan benefit if the limitation of Code Sections 415 and 401(a)(17) did not apply and amounts deferred under Section 3.02 of this Plan had been included in the definition of compensation under the Pension Plan,

(B)                                The benefit amount actually provided on the Participant’s behalf under the Pension Plan.

(b)                                 A Participant’s Accounts shall be credited with the amounts determined pursuant to Section 3.01(a) above at the same time such amounts would have been credited to the Participant’s account in the 401(k) Plan and the Pension Plan, respectively.

(c)                                  The Company shall maintain an Employer SERP Contribution Account on its books on behalf of each Participant who is eligible for an Employer Contribution under the 401(k) Plan.  Throughout the Plan Year, the Company shall credit such Participant’s Employer SERP Contribution Account with an amount equal to (A) reduced by (B) as follows:

(A)                              The Participant’s Employer Contribution calculated by assuming that the limitations of Code Sections 415 and 401(a)(17) did not apply and that the amounts deferred under Section 3.02 of this Plan had been included in the definition of compensation under the 401(k) Plan,

(B)                                The amount of the Employer Contribution actually contributed on the Participant’s behalf under the 401(k) Plan.

Such amount shall be credited to the Participant’s Employer SERP Contribution Account at the same time such amounts would have been credited to the Participant’s Employer Contribution Account maintained for the Participant under the 401(k) Plan.

3.02.                     EMPLOYEE CONTRIBUTIONS

(b)                                 Each participant may also irrevocably elect to defer up to one hundred percent (100%) of any bonuses he is paid by the Company during the Plan Year or any Per Acre Profit Payments he receives during the Plan Year; provided, however, that deferrals of Per Acre Profit Payments shall not be permitted under this Plan on or after January 1, 2005.

(c)                                  Prior to the later of (i) the first day of the Plan Year, or (ii) the 31st day after the Participant becomes eligible to participate in the Plan, each Participant shall enter into a Participation Agreement.  Such Participation Agreement shall be irrevocable, shall apply only to Compensation earned after the date of the Participation Agreement and shall remain in effect for the Plan Year unless the Participant has a Separation from Service.  A Participant may not modify his Participation Agreement during a Plan Year.

3.03.                     ADJUSTMENT TO ACCOUNTS

Each Participant’s Accounts shall be valued at fair market value as of the last day of each Plan Year and such other dates as are selected by the Company.  The Accounts shall reflect the Participant’s aggregate deferral amounts and any earnings or losses attributable to such amounts.

The Participant’s Pension SERP Account shall not be valued under this Section 3.03 but shall reflect the benefit described in Section 3.01(a)(2).

The earnings or losses credited to a Participant’s Accounts shall be based upon the earnings or losses of the investment options applicable to those Accounts pursuant to Section 3.04.  For purposes of crediting earnings or losses as of a valuation date, all contributions under this Plan that have been credited to those Accounts since the prior valuation date will be treated as having been credited as of the prior valuation date.

3.04.                     INVESTMENTS

A Participant may request that his deferrals be allocated among the available investment options established by the Company.  The initial allocation request shall remain in effect for all subsequent deferrals until changed by the Participant.  A Participant may change his or her investment allocation by completing such written or electronic forms as may be required by the Company, and shall become effective as soon as administratively feasible after the Company or other person identified on such forms receives the Participant’s request.  Although the Company intends to invest deferrals according to the Participant’s requests, it reserves the right to invest deferrals without regard to such requests.

The Company may make investment options available pursuant to the Trust.

3.05.                     VESTING

(a)                                  Except as otherwise provided in Appendix B, amounts credited pursuant to Section 3.01(a)(2), as adjusted pursuant to Section 3.03, shall become nonforfeitable when and to the extent they would have become nonforfeitable had they been contributed to the Pension Plan.

(c)                                  Except as otherwise provided in Appendix B, amounts credited pursuant to Section 3.01(c), as adjusted pursuant to Section 3.03, shall become nonforfeitable when and to the extent they would have become nonforfeitable had they been contributed to the Participant’s Employer Contribution Account maintained for the Participant under the 401(k) Plan.

3.06.                     PAYMENT OF BENEFITS

Within ninety (90) days after the earliest of the Participant’s Separation from Service, Disability, death or the date specified by the Participant, the Company shall pay the Participant the vested portion of his Accounts in one of the following methods as elected by the Participant:

(a)                  one lump sum payment; or

(b)                 equal annual installments over a period not to exceed ten (10) years.

The Participant shall elect the date and form of distribution at the same time he or she first completes a Participation Agreement pursuant to Section 3.02.  If the Participant does not elect a date and form of distribution, payment shall be made in one lump sum payment within ninety (90) days after the earliest of the Participant’s Separation from Service, Disability or death.

Notwithstanding the foregoing, prior to December 31, 2007, a Participant may file a one-time election (the “Special Election”) to select a distribution date and method of distribution for his or her Accounts; provided, however, that, with respect to a Special Election made on or after January 1, 2006, and on or before December 31, 2006, such Special Election shall not postpone any payment that was otherwise scheduled to be made during calendar year 2006 nor accelerate payment of any portion of the Participant’s Accounts to a date within calendar year 2006; and provided, further, that, with respect to a Special Election made on or after January 1, 2007, and on or before December 31, 2007, such Special Election shall not postpone any payment that was otherwise scheduled to be made during calendar year 2007 nor accelerate payment of any portion of the Participant’s Accounts to a date within calendar year 2007.  Under any such Special Election, the Participant shall not be required to postpone payment for at least five (5) years after the distribution event.  Such election shall be subject to such administrative rules as the Company may deem necessary or desirable for compliance with Code Section 409A and the notices, regulations and other guidance of general applicability issued thereunder.

With the exception of a Participant’s Special Election, the Participant may elect a new form of distribution; provided, however, that such election must be made at least twelve (12) months prior to the original distribution date and must postpone payment for at least five (5) years after such original distribution date; and provided, further, that such new election shall not be effective if it precedes the Participant’s Separation from Service with the Company by less than one year.

7

Actuarial equivalence under the foregoing paragraphs shall be determined on the basis of the published 1984 Unisex Pension Mortality Table and a 7% interest rate assumption.  Early retirement reductions outlined in Section 4.2 of Retirement Plan A for Employees of American Crystal Sugar Company shall apply; however, additional reductions applied to benefit payments which commence later than the first day of the month following retirement shall not apply.

3.07.                     DEATH BENEFIT

In the event of the death of a Participant prior to payment of a vested portion of the Participant’s Accounts, any unpaid vested amounts shall be paid to the Participant’s Beneficiary pursuant to method of distribution previously elected by the Participant pursuant to Section 3.06.  If no form of distribution has been elected, such amounts shall be paid to such Beneficiary in one lump sum payment as soon as feasible after the Participant’s death.

3.08.                     CONTRIBUTIONS TO TRUST

The Company shall make contributions to the Trust each Plan Year which shall be sufficient to meet the Company’s obligations under the Plan.  These contributions shall be made throughout the Plan Year at such times as the Company may determine and as may be agreed upon with the trustee of the Trust.  Contributions with respect to Accounts other than the Pension SERP Account shall match allocations under this Plan, including any earnings not generated in the Trust (such as earnings attributable to a fixed rate investment option).

3.09.                     BENEFITS UNDER LONG TERM INCENTIVE PLAN

The American Crystal Sugar Company Long Term Incentive Plan established in the year 2000 provides for amounts to be credited to an Account under this Plan.  Accordingly, an Account shall be established under this Plan with respect to those amounts and shall be credited with earnings and losses under the terms of the Plan.  Such Account shall be vested and shall be subject to any additional terms and conditions applicable to that Account under the terms of that Incentive Plan.  Except to the extent permitted by Code Section 409A and the notices, regulations and other guidance of general applicability issued thereunder, this Section 3.09 shall have no further force and effect on or after January 1, 2005.

4.01.                     POWERS

(a)                                  The Company shall appoint one or more persons to administer the Plan.  Such persons shall have, and shall exercise and perform, all of the powers, rights, authorities, and duties necessary to administer the Plan, including the authority and discretion to construe and interpret the Plan, decide all questions of eligibility

(b)                                 The procedures for filing claims for payments under the Plan are described below.  For claims procedures purposes, the “Claims Manager” shall be the Company.

(1)                                  A Participant who believes he or she is entitled to a payment under the Plan may submit a claim for such payment in writing to the Company.  Any claim must be made by the Participant or his or her Beneficiary in writing and state the claimant’s name and the nature of the payment to be made under the Plan on a form acceptable to the Company.  If for any reason a claim under this Plan is denied by the Company, the Claims Manager shall deliver to the claimant a written explanation setting forth the specific reasons for the denial, specific references to the pertinent provisions under the Plan on which the denial is based, a description of any additional material or information necessary for the claimant to perfect the claim and an explanation of why such material or information is necessary, and information on the procedures to be followed by the claimant in obtaining a review of his or her claim, all written in a manner calculated to be understood by the claimant.  For this purpose:  (i) the claimant’s claim shall be deemed to be filed when presented in writing to the Claims Manager and (ii) the Claims Manager’s explanation shall be in writing delivered to the claimant within 90 days of the date the claim is filed.

(2)                                  The claimant shall have 60 days following his or her receipt of the denial of the claim to file with the Claims Manager a written request for review of the denial.  For such review, the claimant or the claimant’s representative may review pertinent documents and submit written issues and comments.

(3)                                  The Claims Manager shall decide the issue on review and furnish the claimant with a copy within 60 days of receipt of the claimant’s request for review of the claimant’s claim.  The decision on review shall be in writing and shall include specific reasons for the decision, written in a manner calculated to be understood by the claimant, as well as specific references to the pertinent provisions in the Plan on which the decision is based.  If a copy of the decision is not so furnished to the claimant within such 60 days, the claim shall be deemed denied on review.  In no event may a claimant commence legal action for benefits the claimant believes are due the claimant until the claimant has exhausted all of the remedies and procedures afforded the claimant by this Section 4.01(b).

4.02.                     COMPANY

Whenever the Company, under the terms of the Plan, is permitted or required to do or perform any act or matter or thing, it shall be done and performed by the Chief Executive Officer of the Company or such officer’s delegate, except with respect to those matters as to which authority is specifically reserved to the Company’s Board of Directors and except for those matters described in Section 2.01.

4.03.                     LIABILITY

Notwithstanding any of the provisions of the Plan to the contrary, neither the Company nor any individual acting as an employee or agent of the Company shall be liable to any Participant or any other person for any claim, loss, liability or expense incurred in connection with the Plan, unless attributable to fraud or willful misconduct on the part of the Company or any such employee or agent of the Company.

ARTICLE V

MISCELLANEOUS

5.01.                     AMENDMENT AND TERMINATION

The Company reserves the power to alter, amend or terminate the Plan at any time and from time to time by the action of the Board of Directors and the interest of each Participant is subject to the powers so reserved.  An amendment shall be authorized by the Board of Directors and shall be stated in an instrument in writing signed in the name of the Company by a person or persons authorized by the Board of Directors.  After the instrument has been so executed, the Plan shall be deemed to have been amended in the manner therein set forth, and all parties interested herein shall be bound thereby.  No amendment to the Plan may alter, impair, or reduce the benefits of a Participant that are vested under the Plan prior to the effective date of such amendment without the written consent of the affected Participant.

Notwithstanding the foregoing, the Company expressly reserves the right to amend the Plan to the extent necessary or desirable to comply with the requirements of Code Section 409A and the regulations, notices and other guidance of general applicability issued thereunder without the consent of any Participant.  Further, in the event the Board of Directors terminates the Plan, such termination and the distribution of all Participants’ benefits shall be made within the time prescribed by and in compliance with Code Section 409A and the regulations, notices and other guidance of general applicability issued thereunder.

5.02.                     NO ALIENATION OF BENEFITS

No payee may assign, anticipate, or otherwise encumber any payment due him under this Plan.  Any payment due to a payee under this Plan shall be exempt from the claims of his creditors.

5.03.                     NO CONTRACT OF EMPLOYMENT

Nothing herein contained shall be construed to constitute a contract of employment between the Company and any Participant.

5.04.                     EXPENSES

The expenses of administering the Plan shall be paid by the Company.

5.05.                     FUNDING

The Plan shall at all times be considered entirely unfunded both for tax purposes and for purposes of Title I of the Employee Retirement Income Security Act of 1974, as amended, and no provision shall at any time be made with respect to segregating assets of the Company for payment of any amounts hereunder.  Any funds with respect to payment to be made hereunder shall continue for all purposes to be part of the general assets of the Company and available to the general creditors of the Company in the event of the Company’s bankruptcy (when the Company is involved in a pending proceeding under the Federal Bankruptcy Code) or insolvency (when the Company is unable to pay its debts as they mature).  No Participant or any other person shall have any interests in any particular assets of the Company by reason of the right to receive a benefit under the Plan and to the extent the Participant or any other person acquires a right to receive benefits under this Plan, such right shall be no greater than the right of any general unsecured creditor of the Company.  The Plan constitutes a mere promise by the Company to make payments to the Participants in the future.  Nothing contained in the Plan shall constitute a guaranty by the Company or any other person or entity that any funds in any trust or the assets of the Company will be sufficient to pay any benefit hereunder.  Furthermore, no Participant shall have any right to a benefit under the Plan except in accordance with the terms of the Plan.

5.06.                     GOVERNING LAW

To the extent not preempted by the laws of the United States of America, the laws of the State of Minnesota shall be the controlling state law in all matters relating to this Plan.

5.07.                     SEVERABILITY

If any provisions of this Plan shall be held illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining parts of this Plan, but this Plan shall be construed and enforced as if the illegal and invalid provisions never had been included herein.

11

5.08.                     INCOMPETENT PARTICIPANTS

If any person entitled to payment under the Plan has been declared incompetent and a conservator or other person legally charged with the care of such person or of his or her estate has been appointed, any distribution under the Plan to which the person is entitled shall be paid to such conservator or other person legally charged with the care of the person or his or her estate.  Except as provided above, when the Company has determined that such person is unable to manage his or her affairs, the Company may provide for such distribution or any part thereof to be made to any other person or institution then contributing toward or providing for the care and maintenance of such person.  Any such distribution shall be a payment for the account of such person and a complete discharge of any liability of the Company and the Plan therefor.

IN WITNESS WHEREOF, this Plan has been executed on behalf of the Company by its duly authorized officers as of the 5th day of December, 2008.
