The provisions of this section shall apply to any Person who acquires Capital Units directly from the Company or through a Disposition by a Member.

3.4 Interests in a Member. A Member that is not a natural person may not cause or permit an interest, direct or indirect, in itself to be Disposed of in violation of the Securities Act of 1933, as amended, or such that, after the Disposition, (a) the Company would be considered to have terminated within the meaning of Section 708 of the Code, or (b) without the consent of the Board of Managers, that Member shall cease to be controlled by substantially the same Persons who control it as of the date of its admission to the Company. On any breach of this Section 3.4, the Company shall have the option to redeem, and on exercise of that option the breaching Member shall surrender, the breaching Member’s Capital Units in accordance with Section 4.3 of this Operating Agreement.

3.5 Information.

(a) In addition to the other rights specifically set forth in this Operating Agreement, each Member is entitled to all information to which that Member is entitled to have access pursuant to the Act under the circumstances and subject to the conditions therein stated. Specifically, any Member and any designated representative thereof shall be permitted access to all records of the Company and may inspect and copy any of them. The Company or its transfer agent shall maintain as part of its books and records and shall make available for inspection by any Member or the Member’s designated agent at the home office of the Company upon the request of the Member an alphabetical list of the names, addresses, and telephone numbers of the Members of the Company along with the number of Capital Units held by each of them (the “Member List”). The Member List shall be updated at least quarterly to reflect changes in the information contained therein. A copy of the Member List shall be mailed to any Member requesting the

Member List within ten days of the request. The copy of the Member List shall be printed in alphabetical order, on white paper, and in a readily readable type size (in no event smaller than 10-point type). A reasonable charge for copy work may be charged by the Company. The purposes for which a Member may request a copy of the Member List include, without limitation, matters relating to Members’ voting rights. If the officers or Managers of the Company neglect or refuse to exhibit, produce, or mail a copy of the Member List as requested, the officers and the Managers shall be liable to any Member requesting the list for the costs, including attorneys’ fees, incurred by that Member for compelling the production of the Member List, and for actual damages suffered by any Member by reason of such refusal or neglect. It shall be a defense that the actual purpose and reason for the requests for inspection or for a copy of the Member List is to secure such list of Members or other information for the purpose of selling such list or copies thereof, or of using the same as a commercial purpose other than in the interest of the applicant as a Member relative to the affairs of the Company. The Company may require the Member requesting the Member List to represent that the list is not requested for a commercial purpose unrelated to the Member’s interest in the Company. The remedies provided hereunder to Members requesting copies of the Member List are in addition to, and shall not in any way limit, other remedies available to Members under federal law, or the laws of any state.

(b) Notwithstanding the foregoing, the Members acknowledge that from time to time, they may receive information from or regarding the Company in the nature of trade secrets or that otherwise is confidential, the release of which may be damaging to the Company or Persons with whom it does business. Each Member shall hold in strict confidence any information it receives regarding the Company that is identified as being confidential (and if that information is provided in writing, that is so marked) and may not disclose it to any Person other than another Member, except for disclosures (i) compelled by law (but the Member must notify the Board of Managers promptly of any request for that information before disclosing it, if practicable), (ii) to advisers or representatives of the Member or Persons who have acquired that Member’s Capital Units through a Disposition as permitted by this Operating Agreement, but only if the recipients have agreed to be bound by the provisions of this section, or (iii) of information that the Member also has received from a source independent of the Company that the Member reasonably believes obtained that information without breach of any obligation of confidentiality. The Members acknowledge that a breach of the provisions of this section may cause irreparable injury to the Company for which monetary damages are inadequate, difficult to compute, or both. Accordingly, the Members agree that the provisions of this section may be enforced by specific performance.

3.6 Liabilities to Third Parties. Except as otherwise expressly agreed in writing, no Member shall be liable for the debts, obligations or liabilities of the Company, including under a judgment, decree or order of a court.

3.7 Withdrawal. A Member does not have the right or power to withdraw from the Company as a Member, except as set forth in this Operating Agreement.

3.8 Lack of Authority. No Member, other than a Member acting in his or her capacity as an officer of the Company, has the authority or power to act for or on behalf of the Company, to do any act that would be binding on the Company, or to incur any expenditures on behalf of the Company, except with the prior consent of the Board of Managers.

ARTICLE 4

DISPOSITION OF CAPITAL UNITS

4.1 General Restrictions on the Disposition of Capital Units.

(a) No Disposition of Capital Units shall be valid except as specifically provided in this Article 4. To be valid, a Disposition must be approved by the Board of Managers and comply with the Company’s Capital Units Transfer System as adopted or approved by the Board of Managers, as it may be amended from time to time. The Capital Units Transfer System shall conform with Section 1.7704-1 et seq. of the Treasury Regulations as adopted or amended by the Internal Revenue Service from time to time, and it is the intent of this Operating Agreement that: (i) the tax status of this Company be the same as for a partnership, (ii) this Company preserve its partnership tax status by complying with Section 1.7704-1, et seq., and any amendments thereto, and (iii) to the extent possible, this Operating Agreement shall be read and interpreted to prohibit

the free transferability of Capital Units. Any attempted Disposition by a Person of Capital Units or any other interest or right, or any part thereof, in or in respect of the Company, other than in accordance with this Article 4 and the Capital Units Transfer System shall be, and is hereby declared, null and void ab initio.

(b) The Board of Managers shall not approve, and the Company shall not recognize for any purpose, any purported Disposition of a Capital Unit unless and until the other applicable provisions of this Article 4 have been satisfied, all conditions have been satisfied under the Capital Units Transfer System, and the Company has received all required documentation in the form adopted by the Board of Managers. If the Person acquiring the Capital Units in the Disposition is not a Member, then such Person must also comply with Section 3.3 of this Operating Agreement. Dispositions of Capital Units, and the resulting admissions of new Members, if applicable, are effective as of the first day of the Quarter following the Quarter in which such matters are approved by the Board of Managers. Upon the Disposition of all or a portion of a Member’s Capital Units, the Company shall transfer to the Member or Members who have acquired the Capital Units that proportion of the capital account of the Member effecting the Disposition which relates to the transferred Capital Units, including amounts representing previously earned but undistributed income and gains. No partial Capital Units may be subject to a Disposition. If a Person becomes the beneficial holder of Capital Units but has not become a Member (whether due to such Person’s failure to sign this Operating Agreement or the Board of Managers’ refusal to accept such Person as a Member upon a Disposition of Capital Units), such Person shall receive the allocations of income, gain, losses, deductions, credits and distributions in accordance with Article 6 of this Operating Agreement until such time as the Person becomes a Member or until such Person’s Capital Units are redeemed in accordance with Section 4.3 of this Operating Agreement. Such Person shall have no voting rights until such time as the Person becomes a Member and complies with this Section 4.1.

(c) The Board of Managers will not approve any Disposition unless (i) either (a) the Disposition is registered under the Securities Act of 1933, as amended, and any applicable state securities laws or (b) the Company has determined that the Disposition is exempt from registration under those laws; and (ii) the Company has determined that the Disposition, when added to the total of all other Dispositions within the preceding 12 months, would not result in the Company being considered to have terminated within the meaning of the Code or losing its partnership status and being taxed as a C corporation within the meaning of the Code.

(d) Any Person admitted to the Company upon a Disposition of Capital Units shall pay, or reimburse the Company for, all costs incurred by the Company in connection with the Disposition or admission on or before the thirtieth day after the receipt by that Person of the Company’s invoice for the amount due. If payment is not made by the date due, the Person owing that amount shall pay interest on the unpaid amount from the date due until paid at the legal rate of interest allowed under South Dakota law.

4.2 Tax Elections. In the event of a Disposition of all or part of the Capital Units of any Member, the Company, in the sole discretion of the Board of Managers, may elect pursuant to Section 754 of the Code (or any successor provisions) to adjust the basis of the assets of the Company.

4.3 Redemption. The Company shall have the right to redeem the Capital Units of a Member or a Person who beneficially holds Capital Units upon any of the following occurrences:

(a) Whenever the Board of Managers by resolution, adopted in good faith and after due investigation, finds that any of the following defaults under the Operating Agreement exist and have not been remedied for a period of 24 months after providing written notice to the defaulting Person identifying the default, describing how such default may be cured and explaining the consequences of this redemption provision:

ARTICLE 5

CAPITAL CONTRIBUTIONS

5.1 Class A Capital Units.

(a) Issuance of Class A Units as Part of the Reorganization. As part of the Reorganization, 14,129,250 Class A Capital Units are being issued to the Cooperative in exchange for all of the Cooperative’s assets and liabilities. The Cooperative is being dissolved and the Class A Capital Units are being distributed to the shareholders of the Cooperative in proportion to the equity shares held by each shareholder of the Cooperative. In the event any shareholder of the

Cooperative fails to execute a counterpart signature page of the Operating Agreement, or fails to consent to the termination of the shareholder’s Member Agreement, the Company shall have the right to redeem such Person’s Class A Capital Units as provided in Section 4.3, in addition to any remedies otherwise provided by law.

(b) Disposition of Class A Units following the Reorganization. After completion of the Reorganization, Class A Members may Dispose of outstanding Class A Capital Units to any Person, subject to the other requirements of this Operating Agreement. Class A Capital Units may only be Disposed of in increments of 250 Capital Units.

(c) Minimum Investment. A Class A Member must always own at least 2,500 Class A Capital Units, and no Person will be admitted as a Class A Member unless said Person holds at least 2,500 Class A Capital Units. If a Person fails to meet this requirement, the Company may redeem the Class A Capital Units held by said Person as provided in Section 4.3.

(d) Maximum Investment. After completion of the Reorganization, no Person and said Person’s Affiliates may at any time hold more than 1.5 percent of the issued and outstanding Class A Capital Units. If a Person violates this limit, the Company may redeem the Class A Capital Units held by said Person in excess of this limitation as provided in Section 4.3.

5.2 Additional Capital Units. Additional Capital Units may be created and issued to new Members or to existing Members on such terms and conditions as the Board of Managers may determine at the time of admission, and may include for the creation of different classes or groups of Members, represented by different classes of Capital Units, which Capital Units may have different rights, powers, and duties. If the Board of Managers creates additional Capital Units, the Board of Managers must specify the terms of admission or issuance, including the amount of Committed Capital proposed to be raised from the issuance of such Capital Units. Members of the Company shall not have a preemptive right to acquire additional, newly created Capital Units of the Company.

5.3 Return of Contributions. A Member is not entitled to the return of any part of its Capital Contribution or to be paid interest in respect of either its capital account or its Capital Contribution. A Capital Contribution is not a liability of the Company or of any Member. Members will not be required to contribute or to lend any cash or property to the Company to enable the Company to return any Member’s Capital Contribution.

5.4 Advances by Members. If the Company does not have sufficient cash to pay its obligations, and the Company does not raise additional capital pursuant to Section 5.3 hereof, any Member(s) that may agree to do so with the consent of the Board of Managers, as appropriate, may advance all or part of the needed funds to or on behalf of the Company. An advance described in this Section constitutes a loan from the Member to the Company, bears interest at the rate negotiated with the Board of Managers from the date of the advance until the date of payment and is not a Capital Contribution.

5.5 Capital Accounts. A capital account shall be established and maintained for each Member pursuant to the requirements of applicable federal income tax regulations. Each Member’s capital account shall be increased and decreased as follows:

(a) Each Member’s capital account shall be increased by: (i) the amount of the initial Capital Contribution made by the Member, (ii) the amount of any additional Capital Contributions made by the Member, and (iii) any income and gains allocated to the Member pursuant to Article 6.

(b) Each Member’s capital account shall be decreased by: (i) any deductions and losses allocated to the Member pursuant to Article 6, and (ii) the amount of any distributions by the Company to the Member as of the time of the distribution.

A Member who has more than one Capital Unit shall have a single capital account that reflects all its Capital Units, regardless of the Class of Capital Units owned by that Member and regardless of the time or manner in which those Capital Units were acquired. Upon the Disposition of a Capital Unit, that portion of the capital account of the Member effecting the Disposition that is attributable to the Capital Unit subject to the Disposition shall carry over to the Person acquiring such Capital Unit.

ARTICLE 6

ALLOCATIONS AND DISTRIBUTIONS

6.1 Allocations and Distributions.

(a) Distributions of Available Cash for Distribution shall be made to the Members for each fiscal year of the Company in accordance with the following provisions:

(i) Tax Distribution. To the Members in an aggregate amount equal to thirty percent of the Company’s net income for such fiscal year, as determined in accordance with generally accepted accounting principles and reported on the financial statements furnished to each Member pursuant to Section 8.21 of this Operating Agreement. Provided, however, that no distribution pursuant to this Section 6.2(a) (i) will be made if the net income for such fiscal year does not exceed $500,000.00, unless the Board of Managers votes to make a distribution notwithstanding that the net annual income for such fiscal year does not exceed $500,000.00.

(ii) Other Distributions. Distributions in excess of the tax distribution made under Section 6.2(a)(i) of this Operating Agreement for any fiscal year may be made upon a vote of the Board of Managers.

(d) No distribution shall be made if the distribution violates or causes the Company to default under the terms of any of the Company’s credit facilities or debt instruments or violates Section 6.10 of this Operating Agreement.

6.3 Allocations of Income, Gain, Loss, Deductions, and Credits. Except as otherwise provided in this Article 6, all items of income, gain, loss, deductions, and credits for a fiscal year shall be allocated to the Members ratably in proportion to their Ownership Percentages.

(a) Allocation of Gain. Income or gain from the sale or other disposition of all or substantially all of the Company’s assets shall be allocated among the Members, first, in such respective amounts as shall cause each Member’s Capital Account (increased by such amounts of income or gain) to bear a ratio to the aggregate Capital Account balance of all Members which, expressed as a percentage, is equal to such Member’s Ownership Percentage, and, thereafter, ratably in proportion to their respective Ownership Percentages.

(b) Allocation of Loss. Any loss from the sale or exchange of all or substantially all of the Company’s assets shall be allocated first, so as to equalize the capital account balances of all Members holding the same number of Capital Units, and thereafter, the remaining losses shall be allocated to the Members, ratably in proportion to their Ownership Percentages.

6.5 Regulatory Allocations and Allocation Limitations. Notwithstanding the preceding provisions for allocating income, gains, losses, deductions and credits, the following limitations, regulatory allocations and contingent reallocations are intended to comply with applicable income tax Treasury Regulations under Section 704(b) of the Code and shall be so construed when applied.

(a) Minimum Gain Chargeback. Notwithstanding any other provision of this Section 6.5, if there is a net decrease in Partnership Minimum Gain during any Company fiscal year, each Member shall be specially allocated items of Company income and gain for such year (and, if necessary, for subsequent years) in accordance with Section 1.704-2(f)(1) of the Treasury Regulations in an amount equal to such Member’s share of the net decrease in Partnership Minimum Gain (determined in accordance with Section 1.704-2(g)(2) of the Treasury Regulations). This Section 6.5(a) is intended to comply with the minimum gain chargeback requirement in the Treasury Regulations and shall be interpreted consistently therewith.

(b) Partner Minimum Gain Chargeback. Except as otherwise provided in Section 1.704-2(i)(4) of the Treasury Regulations, notwithstanding any other provision of this Section 6.5, if there is a net decrease in Partner Nonrecourse Debt Minimum Gain attributable to a Partner Nonrecourse Debt during any Company fiscal year, each Member who has a share of the Partner Nonrecourse Debt Minimum Gain attributable to such Partner Nonrecourse Debt, determined in accordance with Section 1.704-2(i)(5) of the Treasury Regulations, shall be specially allocated items of Company income and gain for such year (and, if necessary, for subsequent years) in an amount equal to such Member’s share of the net decrease in Partner Nonrecourse Debt Minimum Gain attributable to such Partner Nonrecourse Debt, determined in accordance with Section 1.704-2(i)(4) of the Treasury Regulations. Allocations pursuant to the previous sentence shall be made in proportion to the respective amounts required to be allocated to each Member pursuant

thereto. The items to be so allocated shall be determined in accordance with Sections 1.704-2(i)(4) and 1.704-2(j)(2) of the Treasury Regulations. This Section 6.5(b) is intended to comply with the minimum gain chargeback requirements in Section 1.704-2(i)(4) of the Treasury Regulations and shall be interpreted consistently therewith.

(c) Qualified Income Offset. In the event a deficit balance in a Member’s capital account in excess of the sum of (i) the amount such Member is obligated to restore or contribute to the Company pursuant to any provision of this Operating Agreement, and (ii) the amount such Member is deemed to be obligated to contribute pursuant to the penultimate sentences of Section 1.704-2(g)(1)(ii) and 1.704-2(i)(5) of the Treasury Regulations, is caused or increased because a Member receives an adjustment, allocation, or distribution described in Section 1.704-1(b)(2)(ii)(d) of the Treasury Regulations, such Member will be allocated items of Company income and gain in an amount and manner sufficient to eliminate such deficit balance or such increase in the deficit balance, as quickly as possible, to the extent required in the Treasury Regulations. This Section 6.5(c) is intended, and shall be so construed, to provide a “qualified income offset” within the meaning of Section 1.704-1(b)(2)(ii)(d) of the Treasury Regulations.

(d) Gross Income Allocations. In the event that a deficit balance in a Member’s capital account at the end of any fiscal year is in excess of the sum of (i) the amount such Member is obligated to restore or contribute to the Company under this Operating Agreement, and (ii) the amount such Member is deemed to be obligated to restore pursuant to the penultimate sentences of Treasury Regulations §§ 1.704-2(g)(1)(ii) and 1.704-2(i)(5), the Member shall be specially allocated items of Company income and gain in the amount of such excess as quickly as possible, provided that an allocation pursuant to this Section 6.5(d) shall be made only if and to the extent that the Member would have a deficit balance in its capital account in excess of such sum after all other allocations provided for in this Section have been made as if Section 6.5(c) and this Section 6.5(d) were not in this Operating Agreement.

(e) Nonrecourse Deductions. Nonrecourse Deductions shall be specially allocated to the Members in proportion to the allocation of Losses under Section 6.3.

(f) Partner Nonrecourse Deductions. Any Partner Nonrecourse Deductions for any fiscal year shall be specially allocated to the Member who bears the economic risk of loss with respect to the Partner Nonrecourse Debt to which such Partner Nonrecourse Deductions are attributable in accordance with Section 1.704-2(i)(1) of the Treasury Regulations.

(g) Members’ Shares of Excess Nonrecourse Debt. The Members’ shares of excess Partnership Nonrecourse Debt within the meaning of Section 1.752-3(a)(3) of the Treasury Regulations shall be determined in accordance with the manner in which it is reasonably expected that the deductions attributable to such Partnership Nonrecourse Debt will be allocated.

(h) Curative Allocations. The allocations set forth in subsections (a), (b), (c), (d), (f) and (g) (the “Regulatory Allocations”) are intended to comply with certain requirements of the Treasury Regulations under Section 704(b). Notwithstanding any other provision of this Article 6 (other than the Regulatory Allocations), the Regulatory Allocations shall be taken into account in allocating other items of income, gain or loss among the Members so that, to the extent possible, the net amount of allocations of such items of income, gain or loss and the Regulatory Allocations to each Member shall be equal to the net amount that would have been allocated to

such Member if the Regulatory Allocations had not occurred. For this purpose, future Regulatory Allocations under Section 6.5(a) and (b) shall be taken into account that, although not yet made, are likely to offset other Regulatory Allocations made under Section 6.5(f) and (g).

6.6 Proration of Allocations. All income, gains, losses, deductions and credits for a fiscal year allocable with respect to any Members whose Capital Units may have been transferred, forfeited, reduced or changed during such year should be allocated based upon the varying interests of the Members throughout the year. The precise manner in which such allocations are made shall be determined by the Board of Managers in its sole discretion and shall be a manner of allocation, including an interim closing of the books, permitted to be used for federal income tax purposes.

6.7 Consent to Allocation. Each Member expressly consents to the methods provided herein for allocation of the Company’s income, gains, losses, deductions and credits.

(b) A Member who receives a distribution that is not permitted under this Operating Agreement has no liability to return the distribution unless the Member knew that the distribution was prohibited under the terms of this Operating Agreement or the Act.

(c) Any Person dealing with the Company, other than a Member, may rely on the authority of the Manager or any officer of the Company in taking any action in the name of the Company without inquiry into the provisions of this Operating Agreement or compliance herewith, regardless of whether that action actually is taken in accordance with the provisions of this Operating Agreement.

8.3 Registration and Transfer of Securities. Securities and other property owned by the Company shall be registered in the Company’s name, in a nominee name, in any such case for the benefit of the Company. Any transfer agent called upon to transfer any securities to or from the name of the Company or such other names shall be entitled to rely on instructions or assignments signed by an officer of the Company, or by any agent or custodian so authorized by the Board of Managers, on its behalf, without inquiry as to the authority of the person signing such instructions or assignments or as to the validity of any transfer to or from the name of the Company. At the time of transfer, any transfer agent is entitled to assume, unless it has actual knowledge to the contrary:

(a) that the Company is still in existence;

(b) that this Operating Agreement is in full force and effect and has not been amended, unless the transfer agent has received written notice to the contrary; and

8.4 Number; Term of Office; Election.

(a) The number of initial Managers of the Company shall be set at 21 until such time as the Members vote to change the number of Managers serving on the Board of Managers. If the number of Managers is increased, the newly created Manager positions shall be filled at the next annual meeting by election by the Members. If the number of Managers is decreased, then the decrease shall coincide with an annual or special meeting and all Managers shall be subject to reelection by the Members. Each initial Manager shall hold office according to the provisions of Section 8.4(b) unless such Manager resigns, dies, or becomes disabled.

(b) A person must be a Member or a representative owner of a Member of the Company to be elected to the Board of Managers. Each initial Manager shall serve on the Company’s Board of Managers until his term would have expired on the Cooperative’s board of directors, resulting in staggered elections of seven Managers annually. Thereafter each Manager shall be elected to office by the Members for a term of three years or until the Manager’s earlier resignation or removal. No Manager may serve more than three consecutive three year terms on the Board of Managers, and the original terms of the initial Managers’ as directors of the Cooperative shall be included in calculating length of service. If a Manager’s term expires, the Manager shall continue to serve until the Manager’s successor shall have been elected and qualified. If a Manager is appointed to complete an unexpired term, that portion of the unexpired term served shall not be counted when calculating the Manager’s length of service.

(c) At each annual meeting one Manager shall be elected from each of seven geographic districts. The seven geographic districts are those originally set by the board of directors of the Cooperative. It is intended that each of the seven geographic districts have approximately equal numbers of Members located in each district. Boundaries of districts may be changed by a majority vote of the Members at an annual or special meeting of the Members. However, if the boundaries are changed by a vote taken at an annual meeting, the change of district boundaries shall not be effective until adjournment of the annual meeting so that the election of Managers to be held during said annual meeting shall be completed under the former district boundaries.

(d) If a representative of a Member that is a partnership, firm, corporation, limited liability company, unincorporated association or cooperative is seeking election to the Board of Managers, the representative owner of a Member of the Company shall seek election within the district in which the Member is located. For the purpose of electing Managers, a Member shall be deemed to be located in a given district if the Member’s principal residence is located within the district for a Member that is an individual, and if the Member’s chief executive office is located within the district for a Member that is a partnership, firm, corporation, limited liability company, unincorporated association or cooperative. If a Manager’s principal residence or the Member’s chief executive office, whichever is applicable, should change from one district to another during a Manager’s term, because of a change in location of the principal residence or chief executive office, whichever is applicable, or because the Members vote to change the boundaries of a Manager’s district, said Manager may complete his or her term, but may not seek re-election within the former district upon completion of the current term.

(e) A Manager shall be elected by a plurality of the votes cast by the Members from the Manager’s district voting in the election, with each Member having one vote per position and no cumulative voting. Other aspects of the election process shall be determined by the Board of Managers in advance of the annual election.

8.5 Death or Disability of Managers. Upon the death or disability of a Manager, the resulting vacancy on the Board of Managers may be filled in accordance with Section 8.8.

8.6 Removal. Managers may be removed for any reason at any annual or special meeting of Members by the affirmative vote of the majority of the Members. The notice calling such meeting shall give notice of the intention to act upon such matter, and if the notice so provides, the vacancy caused by such removal by the Members may be filled at such meeting by vote of the Members represented at such meeting. Managers may also be removed for any reason by a Super Majority Vote of the Board of Managers. The vacancy caused by such removal by the Board of Managers may be filled by the remaining members of the Board of Managers as provided in Section 8.8 of this Operating Agreement.

8.7 Resignations. Any Manager may resign at any time. Such resignation shall be made in writing and shall take effect at the time specified therein, or, if no time be specified then at the time of its receipt by the President or the Secretary. The acceptance of a resignation shall not be necessary to make it effective, unless expressly so provided in the resignation.

8.8 Vacancies. Any vacancy occurring in the Board of Managers (other than by reason of an increase in the number of Managers) may be filled by appointment through the affirmative vote of a majority of the remaining Managers, though less than a quorum of the Managers. A Manager appointed by the Board of Managers to fill a vacancy shall serve until the next annual meeting or special meeting of

Members held for the purpose of electing Managers, at which time, the Members shall elect a new Manager to serve for the remainder of the original unexpired term of the vacated position. Any Manager position to be filled by reason of an increase in the number of members on the Board of Managers shall be filled by election at an annual meeting or at a special meeting of Members called for that purpose.

8.9 Place and Manner of Meetings. Meetings of the Board of Managers, regular or special, may be held either within or without the State of South Dakota. Managers may participate in such meetings by means of conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other, and participation in a meeting as provided herein shall constitute presence in person at such meeting, except where a person participates in the meeting for the express purpose of objecting to the transaction of any business on the ground that the meeting is not lawfully called or convened.

8.10 First Meeting. The first meeting of the newly elected Managers shall be held without further notice within 60 days following the annual meeting of the Members, and at the same place, unless by unanimous consent of the Board of Managers then elected and serving, such time or place shall be changed.

8.11 Regular Meeting of Board of Managers. A regular meeting of the Board of Managers may be held at such time as shall be determined from time to time by resolution of the Board of Managers.

8.12 Special Meeting of Board of Managers. The Secretary shall call a special meeting of the Board of Managers whenever requested to do so by the President, Chief Executive Officer, or by any three of the Managers. Such special meeting shall be held at the time specified in the notice of the meeting. Neither the business to be transacted at, nor the purpose of, any special meeting need be specified in a notice or waiver of notice.

8.13 Notice of Board of Managers’ Meetings. All special meetings of the Board of Managers shall be held upon two 2 days’ written or oral notice stating the date, place and hour of meeting delivered to each Manager either personally or by facsimile transmission, or upon five days’ written notice by mail, at the direction of the President, Chief Executive Officer, the Secretary, or Managers calling the meeting.

8.14 Action Without Meeting. Any action that can be taken at a meeting of the Board of Managers, or any action which may be taken at a meeting of the Board of Managers, may be taken without a meeting if a consent in writing, setting forth the action so taken, shall be signed by a Super Majority Vote of the Board of Managers. Such consent shall have the same force and effect as if adopted at a duly called meeting of the Board of Managers.

8.15 Quorum; Majority Vote. At all meetings of the Board of Managers, a majority of the members of the Board of Managers shall constitute a quorum for the transaction of business. Except as otherwise provided in this Operating Agreement, the act of a majority of the Managers present at any meeting at which a quorum is present shall be the act of the Board of Managers. If a quorum shall not be present at any meeting of the Board of Managers, the Managers present thereat may adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum is present.

8.16 Approval or Ratification of Acts or Contracts. The Board of Managers in its discretion may submit any act or contract for approval or ratification at any annual meeting of the Members, or at any special meeting of the Members called for the purpose of considering any such act or contract, and

any act or contract that shall be approved or be ratified by the Members shall be as valid and as binding upon the Company and upon all the Members as if it shall have been approved or ratified by every Member of the Company.

8.17 Interested Managers, Officers and Members. No contract or transaction between the Company and one or more of its Managers, officers, or Members, or any of their Affiliates, or between the Company and any other limited liability company, corporation, partnership, association or other organization in which one or more of its Managers or Members are managers or officers or have a financial interest, shall be void or voidable solely for this reason or solely because the Person is present at or participates in the meeting of the Board of Managers or of a committee formed by the Board of Managers which authorizes the contract or transaction. Subject to 8.1(d), only disinterested Managers may vote on any particular matter or issue.

8.18 Expenses of the Company.

(a) General and Administrative Expenses. All expenses of the Company shall be billed to and paid by the Company. The Managers may be reimbursed for the actual cost of goods and services used for or by the Company. Managers may be reimbursed for administrative services and costs incurred by the Manager that are incidental to the Manager’s role as a Manager of the Company and necessary to the prudent operation of the Company; provided, the reimbursement shall be the lower of the Manager’s actual cost or the amount the Company would be required to pay persons other than Affiliates for comparable administrative services in the same geographic location; and provided, further, that such costs are reasonably allocated to the Company on the basis of assets, revenues, time records or other method conforming with generally accepted accounting principles. No reimbursement shall be permitted for services for which the Manager is entitled to compensation by way of a separate fee.

(b) Organizational and Reorganization Expenses. Organization expenses incurred in connection with the formation of the Company and all expenses in connection with the Reorganization will be charged to and borne by the Company. To the extent any such organization and reorganization expenses have been paid by the Board of Managers, the Board of Managers will be reimbursed in a like amount by the Company.

The annual report will include the amount and nature of any compensation paid to the officers and Managers and their Affiliates during the period, including a description of the services performed in relation thereto, and will otherwise be in such form and have such content as the Board of Managers deems proper.

Subject to this Article 11, if any Member becomes a Bankrupt Member, the Bankrupt Member’s Capital Units shall be offered for sale through the Capital Units Transfer System at a price reasonably low

enough to generate a sale. The payment to be made to the Bankrupt Member or its representative as a result of such sale pursuant to this Article 11 is in complete liquidation and satisfaction of all the rights and interest of the Bankrupt Member and its representative (and of all Persons claiming by, through, or under the Bankrupt Member and its representative) and in respect of the Company, including, without limitation, any Capital Units, any rights in specific Company property, and any rights against the Company and (insofar as the affairs of the Company are concerned) against the Members, and constitutes a compromise to which all Members have agreed.

13.1 Liquidation and Termination. On dissolution of the Company, the Board of Managers shall proceed diligently to wind up the affairs of the Company and make any final distribution as provided in this Operating Agreement and the Act.

Upon an event of liquidation, the business of the Company shall be wound up, the Board of Managers shall take full account of the Company’s assets and liabilities, and all assets shall be liquidated as promptly as is consistent with obtaining the fair value thereof. If any assets are not sold, gain or loss shall be allocated to the Members in accordance with Article 6 as if such assets had been sold at their fair market value at the time of the liquidation. If any assets are distributed to a Member, rather than sold, the distribution shall be treated as a distribution equal to the fair market value of the asset at the time of the liquidation. The assets of the Company shall be applied and distributed in the following order of priority:

(a) to the payment of all debts and liabilities of the Company, including all fees due the Members and Affiliates, and including any loans or advances that may have been made by the Members to the Company, in the order of priority as provided by law;

13.3 Deficit Capital Account Balances. Notwithstanding anything to the contrary contained in this Operating Agreement, and notwithstanding any custom or rule of law to the contrary, to the extent that the deficit, if any, in the capital account of any Member results from or is attributable to deductions and losses of the Company (including non-cash items such as depreciation), or distributions of money pursuant to this Operating Agreement to all Members in proportion to their respective Ownership Percentages, upon dissolution of the Company such deficit shall not be an asset of the Company and such Members shall not be obligated to contribute such amount to the Company to bring the balance of such Member’s capital account to zero.

14.2 Headings. The headings used in this Operating Agreement have been inserted for convenience only and do not constitute matter to be construed in interpretation of this Operating Agreement.

14.3 Construction and Severability. Whenever the context so requires, the gender of all words used in this Operating Agreement includes the masculine, feminine, and neuter, and the singular shall include the plural, and conversely. All references to Articles and Sections refer to articles and sections of this Operating Agreement, and all references to Exhibits, if any, are to Exhibits attached hereto, if any, each of which is made a part hereof for all purposes. If any portion of this Operating Agreement shall be invalid or inoperative, then, so far as is reasonable and possible:

(a) The remainder of this Operating Agreement shall be considered valid and operative; and

14.4 Effect of Waiver or Consent. A waiver or consent, express or implied, to or of any breach or default by any Person in the performance by that Person of its obligations with respect to the Company is not a consent or waiver to or of any other breach or default in the performance by that Person of the same or any other obligations of that Person with respect to the Company. Failure on the part of a Person to complain of any act of any Person or to declare any Person in default with respect to the Company, irrespective of how long that failure continues, does not constitute a waiver by that Person of its rights with respect to that default until the applicable statute-of-limitations period has run.

14.9 Conflicting Provisions. To the extent that one or more provisions of this Operating Agreement appear to be in conflict with one another, then the Board of Managers shall have the right to choose which of the conflicting provisions are to be enforced. Wide latitude is given to the Board of Managers in interpreting the provisions of this Operating Agreement to accomplish the purposes and objectives of the Company, and the Board of Managers may apply this Operating Agreement in such a

manner as to be in the best interest of the Company, in its sole discretion, even if such interpretation or choice of conflicting provisions to enforce is detrimental to one or more Members.

(a) The Board of Managers may not adopt, amend or repeal a provision in this Operating Agreement, if the Members in adopting, amending or repealing a provision in this Operating Agreement expressly provide that the Board of Managers may not amend or repeal the provision; and
