     (i) result in violation of the Securities Act, any applicable state law or the applicable securities laws of any other jurisdiction;

     (ii) result in the Transfer of an Interest or an Economic Interest of a Member to a direct or indirect competitor of the Company;

     (iii) result in a violation of any law, rule, or regulation by the Member, any other Member, any Manager or the Company;

     (iv) cause the Company to be deemed a “publicly traded partnership” as such term is defined in Section 7704(b) of the Code; or

     (v) cause the termination or dissolution of the Company.

     4.4.3. Transfers of Economic Interest Only. In the event of any Transfer made in accordance with this Section 4.4, the transferee shall receive only the transferor’s Economic Interest in the Company, and the transferee shall not be admitted as a Member or have any right as a result of such Transfer to participate in the affairs of the Company as a Member, unless such transferee is also admitted as a Substitute Member in accordance with Section 4.5.

     4.4.4. Void Transfers. Any voluntary or involuntary Transfer in violation of this Section 4.4 or the requirements of Article 12 shall be null and void ab initio, and shall not operate to Transfer any portion of any Interest or Economic Interest in the Company to the purported transferee.

     4.5. Admission of Substitute Members. An Assignee of Units of the Company shall be admitted as a Substitute Member only upon the approval of a Super-majority of the Managers. If so admitted, the Substitute Member shall have all the rights and powers, and shall be subject to all the restrictions and liabilities of, the Member who assigned such Units to the extent that such rights powers, restrictions and liabilities resulted from such assigning Member’s ownership of the

assigned Units. The admission of a Substitute Member shall not release any Member who assigned such Units from liabilities or obligations to the Company, the other Members or any other Person that may have arisen prior to the Transfer.

     4.6. Rights of Assignees. Unless and until it is a Substitute Member, the Assignee of any Units shall have no right to vote on, consent to, approve or participate in the determination of any matter, or to otherwise participate in the management of the business and affairs of the Company or to become a Member, which rights shall be retained by the Member or Substitute Member who Transferred the applicable Units to the Assignee. Unless it is a Substitute Member, the Assignee is only entitled to receive distributions (including its return of capital) and to be allocated the Profits and/or Losses, as the case may be, attributable to the Units Transferred to the Assignee.

     4.7. Additional Members. One or more Additional Members of the Company may be admitted to the Company as a Member upon the approval of the Managers and such Persons shall be admitted as Members of the Company; provided that (i) the issuance of new Units to be held by such Additional Member has been approved in accordance with Section 3.1, and (ii) such Additional Members execute a counterpart signature page to this Agreement agreeing to be bound by the terms of this Agreement and any other agreements or instruments by which a Member is bound as a condition to or by virtue of the Member’s ownership of Units.

     4.8. Resignation or Withdrawal of a Member. Except as specifically provided in this Agreement, no Member shall have the right to resign or withdraw from membership in the Company or withdraw its interest in the capital of the Company.

     4.9. Disassociation of a Member. The incapacity, death, Bankruptcy or Dissolution of a Member or the redemption by the Company of all of such Member’s Units: (a) will cause such Member to become a Disassociated Member; and (b) will terminate the membership of such Member in the Company. A Disassociated Member shall have no right to participate in the management of the business and affairs of the Company, but shall be entitled only to receive distributions and any other share of profits to which the Disassociated Member would have been entitled under this Agreement but for the incapacity, death, Bankruptcy or Dissolution of such Member.

     4.10. Rights of a Disassociated Member.

     4.10.1. Purchase Option of Disassociated Member’s Interests. In the event any Member becomes a Disassociated Member, the Disassociated Member or its legal representative, successor or assign may request admission to the Company as a Substitute Member pursuant to Section 4.5 within ten (10) days of the event triggering the disassociation (the “Date of Disassociation”). If no request for Substitute Member status is made and granted pursuant to Section 4.5, the remaining Member(s) may elect, within thirty (30) days of the expiration of the date by which such request was to be made (if no request is made), or the date on which such request is denied (if such a request is not approved by the Managers) (the “Disassociation Purchase Option Date”), to purchase the Dissociated Member’s interest on such terms and conditions as the remaining Members and the Dissociated Member or its legal representative, successor or assign may agree. If

the remaining Members and the Dissociated Member or its legal representative, successor or assign do not agree, the remaining Members shall have an option (to be exercised within sixty (60) days after the Disassociation Purchase Option Date by giving notice to the Disassociated Member or its legal representative, successor or assign, as applicable) to purchase the interest, for the Contract Price as specified in Section 4.10.2. The number of Units of such Dissociated Member’s interest that a Member shall be entitled to purchase pursuant to this Section 4.10.1 shall be determined based upon the proportion that the Percentage Interest of such Member bears to the aggregate of the Percentage Interests of all of the Members electing to purchase the Dissociated Member’s interest. In the event any Member elects to purchase none or less than all of his, her or its pro rata share of such Dissociated Member’s interest, then the other Members may elect to purchase more than their pro rata share. If no request for Substitute Member status is made and granted pursuant to Section 4.5, and the remaining Members do not exercise their options under this Section 4.10, the Disassociated Member or its legal representative, successor or assign shall thereafter have only those rights of an Assignee under this Agreement.

     4.10.2. Contract Price. The “Contract Price” shall equal the fair market value of the Disassociated Member’s Interest as of the Date of Disassociation. The fair market value shall be determined within sixty (60) days after the Disassociation Purchase Option Date by agreement among the Members, or if no agreement can be reached, then by an appraisal (the appraiser shall be selected in accordance with Section 4.10.3) of the fair market value of the Member’s Interest.

     4.10.3. Selection of Appraiser. If the appraisal of an Interest is required pursuant to Section 4.10.2, then the parties shall attempt to agree on the selection of an appraiser. If the parties cannot agree on an appraiser, then the Member (or such Member’s representative) whose Interest is being transferred shall select a qualified appraiser and the Company (at the direction of a Super-majority of the Managers) shall select a second qualified appraiser. The two appraisers shall then select a third qualified appraiser. The two appraisers selected by the transferring Member and the Company shall prepare appraisals of the fair market value, and shall present those appraisals to the third appraiser. The third appraiser acts as an arbitrator and determines the fair market value by selecting either (i) one of the two appraisals presented, or (ii) a value between the two appraisals presented. If the Members use one appraiser, then the cost of the appraiser shall be split between the transferring Member and the Company. If the Members use three appraisers, then: (A) the cost of the appraiser selected by the transferring Member and one-half of the cost of the third appraiser shall be borne by the transferring Member; and (B) the cost of the appraiser selected by the Company and one-half of the cost of the third appraiser shall be borne by the Company. The decision of the appraiser or appraisers shall be final and binding upon the Members and the Company.

     4.11. No Authority as Agent. No Member shall have the authority in its capacity as a Member to enter into any transaction on behalf of the Company or to otherwise bind the Company.

     4.12. Interest in Property of the Company. Each Member’s Interest in the Company shall for all purposes be personal property. No Member shall have any interest in specific Company property. All property of the Company, whether real or personal, tangible or intangible, shall be deemed to be owned by the Company as an entity, and no Member, individually, shall have any direct ownership in such property.

     4.13. Information Rights. In addition to other rights provided by this Agreement or by applicable law, a Member shall have the right on demand and at such Member’s own expense:

     4.13.1. To obtain any and all information regarding the status of the business and financial condition of the Company;

     4.13.2. Promptly after becoming available, to obtain a copy of the Company’s Federal, state, and local income tax returns for each year;

     4.13.3. To have furnished to it a current list of the name and last known business, residence or mailing address of each Member;

     4.13.4. To obtain information regarding the Capital Contributions made by each Member;

     4.13.5. To receive a copy of this Agreement and the Articles and all amendments, together with copies of any powers of attorney pursuant to which this Agreement, the Articles, and all amendments that have been executed; and

     4.13.6. To inspect and copy any of the Company’s books and records and obtain such other information regarding the affairs of the Company during normal business hours.

     4.14. Voting Rights. Except as expressly required by law or as provided in this Agreement, Members shall have no voting, approval or consent rights. In matters on which Members are entitled to vote, each Voting Unit carries one vote. Whenever this Agreement references an action to be taken by the Members, such reference, unless otherwise stated, presumes that such action requires the vote or consent of a majority in interest of the Voting Units issued and outstanding. Notwithstanding the foregoing, the issuance of new Units will require the approval of seventy-five percent (75%) of the Voting Units. Actions and decisions requiring the approval of the Voting Members pursuant to any provision of this Agreement may be authorized or made either by vote of the requisite percentage of interest of Voting Members taken at a meeting of the Voting Members, or by unanimous written consent of all Voting Members. A corporate Voting Member may cast its vote through any of such Voting Member’s duly authorized officers.

     4.15. Member Meetings. Member Meetings may be called by any Member or Manager, by giving at least five (5) Business Days’ prior notice of the time, place and purpose of the meeting to all Members. Any such meeting shall be held during the Company’s normal business hours at its principal place of business, unless all of the Members consent in writing or by their attendance at such meeting to its being held at another location or time. A Member may attend such meeting by telephone or videoconference.

     4.16. Adjournment. When a meeting is adjourned to another time or place, a notice of the adjourned meeting shall be given in accordance with Section 4.15. At the adjourned meeting, the Company may transact any business that might have been transacted at the original meeting.

     4.17. Waiver of Notice; Consent to Meeting. The actions taken at any meeting, however called and noticed, and whenever held, are as valid as though the action was taken at a meeting duly held, if a quorum is present either in person or by proxy, and if, either before or after the meeting, each Member entitled to vote, but not present in person or by proxy, approves by signing a written waiver of notice or an approval to the holding of the meeting or an approval of the minutes thereof. All waivers, consents, and approvals shall be filed with the Company records or made a part of the minutes of the meeting. A Member’s attendance at a meeting shall constitute a waiver of notice of the meeting, except when such Member objects, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened; and except that attendance at a meeting is not a waiver of any right to object to the consideration of matters required to be included in the notice of the meeting, but not so included, if the objection is expressly made at the meeting.

     4.18. Quorum. A majority in interest of the Voting Members, represented in person or by proxy, shall constitute a quorum at a meeting of Members. In the absence of a quorum, any meeting of Members may be adjourned from time to time by the Members represented either in person or by proxy pursuant to Section 4.16.

     4.19. Vote by Proxy. A Voting Member may vote by proxy given to any other Member. Any such proxy must be in writing and must identify the special meeting or matter to which the proxy applies or state that it applies to all matters coming before the Company for approval prior to a specified date in the proxy under any provision of this Agreement. Any such proxy shall be revocable at any time and shall not be effective at any meeting at which the Voting Member giving such proxy is in attendance.

     4.20. Records of Meeting. The Company shall maintain records of all actions taken by the Voting Members pursuant to any provision of this Agreement, including minutes of all Company meetings, copies of all actions taken by consent of the Voting Members and copies of all proxies pursuant to which one Voting Member votes or executes a consent on behalf of another.

Except as otherwise agreed to in writing by the assignor and assignee of a Unit and approved by the Managers, in the event the assignor of such Unit retains any other Units, the assignor’s Capital Account balance shall be divided between the assignor and the assignee in accordance with their respective Percentage Interests of all Units held by such Persons.

The foregoing provisions and the other provisions of this Agreement relating to the maintenance of Capital Accounts are generally intended to comply with Regulations section 1.704 l(b) and must be interpreted and applied in a manner consistent with those Regulations.

ARTICLE VII
DISTRIBUTIONS.

     7.1. Distributions of Net Proceeds from Profits. Subject to the provisions set forth in this Article 7, the timing and amount of all distributions shall be determined by a Super-majority of the Managers.

     7.2. Priority of Distributions of Net Proceeds from Profits. If the Managers make a distribution of the Net Proceeds from Profits to the Members in accordance with the provisions of Section 7.1, then such proceeds shall be distributed to the Members by the Company in the following order of priority:

     (i) First, to each Voting Member and each Non-Voting Member, an amount equal to the Tax Distribution Amount, if any, determined for such Member (including any Tax Distribution Amount payable in respect of amounts allocated to the Non-Voting Members pursuant to Section 8.2.1(ii));

     (ii) Second, 100% to the Non-Voting Members until the Non-Voting Members shall have received an amount equal to the aggregate accrued but undistributed Preferred Return Amount, less the aggregate amount, if any, previously distributed to the Non-Voting Members pursuant to this Section 7.2(ii);

     (iii) Finally, any remaining Net Proceeds from Profits shall be distributed to all of the Voting Members pro rata in proportion to their respective Percentage Interests.

     7.3. Tax Distributions. To the extent (i) sufficient Net Proceeds exist, and (ii) permissible under Oklahoma law, and subject to the restrictions set forth in Section 7.4, the Managers shall cause the Company to make aggregate annual distributions to the Voting and Non-Voting Members of no less than an amount equal to the Tax Distribution Amounts. The

Managers may cause the Company to make such distributions of Tax Distribution Amounts quarterly or at such other times as the Managers may determine. Distributions of Tax Distribution Amounts shall not be considered to be a distribution of amounts under Section 7.2(ii), Section 7.2(iii), or Section 7.2(iv), and Tax Distribution Amounts shall not reduce the Preferred Return Amount, the Original Issue Price for the Non-Voting Units, or otherwise be considered as distributions to the Members of amounts that would otherwise be distributable to the Members under Section 7.2.

     7.4. Restrictions on Distributions. The following restrictions on distributions shall apply to all distributions made by the Company to the Members:

     7.4.1. The Company shall not make any distribution to the Members unless, immediately after giving effect to the distribution, all liabilities to creditors of the Company, other than liabilities as to which recourse of creditors is limited to specified property of the Company, do not exceed the fair market value of the Company property (including intangible assets); provided, however, that the fair value of any property that is subject to a liability as to which recourse of creditors is so limited shall be included in the Company assets only to the extent that the fair value of the property exceeds such liability.

     7.4.2. The Company shall not make any distribution to the Members unless, immediately after giving effect to the distribution, the Company shall have sufficient cash available to meet the reasonably anticipated needs of the Company, as such needs are determined in the sole discretion of the Managers.

     7.4.3. The Company shall not make any distribution to the Members to the extent such distribution would result in a default under, or a violation of or cause the acceleration of any indebtedness under, any credit or loan agreement with the Company.

     7.5. Return of Distributions. Members and Assignees who receive distributions made in error or in violation of the Act or this Agreement shall hold such improper distributions in trust for, and promptly return such improper distributions to, the Company. Except for such improper distributions, no Member or Assignee shall be obligated to return any distribution to the Company or pay the amount of any distribution for the account of the Company or to any creditor of the Company. The amount of any distribution returned to the Company by a Member or Assignee or paid by a Member or Assignee for the account of the Company or to a creditor of the Company shall be added to the Capital Account(s) from which it was subtracted when it was distributed to the Member or Assignee.

     7.6. No Other Withdrawals. Except as provided in this Article 7 or Article 11, no withdrawals or distributions shall be required or permitted.

     7.7. In-Kind Distributions. If property is distributed in-kind to the Members, the difference between the gross fair market value of such property (as determined by the Managers) and its Gross Asset Value shall be considered gain or loss that is recognized by the Company and such gain or loss shall be allocated to the Members in accordance with the provisions of Article 8.

     7.8. Withholding on Distributions. All amounts required to be withheld pursuant to the Code or any provision of any state, local or foreign tax law with respect to any payment, distribution or allocation to the Company or any Member and treated by the Code (whether or not withheld pursuant to the Code) or any such tax law as amounts payable by or in respect of any Member or any Person owning an interest, directly or indirectly, in such Member shall be treated as amounts distributed to the Member for purposes of Section 7.2. The Managers are authorized to withhold from distributions, or with respect to allocations, to the Members and to pay over to any federal, state, local or foreign government any amounts required to be so withheld pursuant to the Code or any provisions of any other federal, state, local or foreign law and shall allocate any such amounts to the Member with respect to which such amount was withheld.

     7.9. Distributions and Capital Accounts. The provisions in this Agreement regarding the maintenance of Capital Accounts and allocations of Profits, Loss, and other items of Company income, gain, loss or deduction are intended to effect an allocation of tax items of the Company that are in accordance with the Members’ “interests in the partnership” within the meaning of Regulations Section 1.704-1(b)(3) by utilizing the principles of allocation contained in Regulations Section 1.704-1(b)(2)(iv) and Regulations Section 1.704-2 with respect to maintenance of capital accounts and allocations, and shall be interpreted and applied accordingly. For purposes of applying the provisions of this Agreement with respect to Capital Accounts, it shall be assumed that the Company satisfies the requirements of Regulations Sections 1.704-1(b)(2)(ii)(b)(2) and (3). Capital Account balances shall not be used to determine the amount or timing of distributions to the Members pursuant to the Agreement.

ARTICLE VIII
ALLOCATIONS

     8.1. Percentage Interests. The initial Percentage Interest of each Member shall be as set forth in Exhibit A (as it may be amended in accordance with the terms of this Agreement).

     8.2. Allocation of Profits and Losses.

     8.2.1. Allocation of Profits. After giving effect to the allocations set forth in Section 8.3 and Section 8.4, Profits for the relevant Accounting Period shall be allocated to the Members in the following manner:

     (i) First, the Profits for such Accounting Period shall be allocated to the Non-Voting Members and Voting Members to the extent any Losses were allocated to these Non-Voting Members and Voting Members, as the case may be, pursuant to Section 8.2.2, and which have not been previously offset by any allocations of Profits pursuant to this Section 8.2.1, to be allocated among these Non-Voting Members and Voting Members in the inverse order that such Losses were allocated to these Non-Voting and Voting Members under Section 8.2.2;

     (ii) Second, the Profits shall be allocated 100% to the Non-Voting Members in an amount equal to the aggregate Preferred Return Amount accrued in respect of the Non-Voting Units as of the end of the relevant Accounting

Period, minus the aggregate amount, if any, previously allocated to the Non-Voting Members pursuant to this Section 8.2.1(ii); and

     (iii) Finally, any remaining Profits shall be allocated to the Voting Members pro rata in proportion to their respective Percentage Interests.

     8.2.2. Allocation of Losses. After giving effect to the allocations set forth in Section 8.3 and Section 8.4, and subject to the limitation set forth in Section 8.2.3, Losses for any Fiscal Year will be allocated to the Members in the following order and priority: (i) first, to the Voting Members, in an amount up to, and in proportion to, the Profits allocated to these Voting Members under Section 8.2.1(iii), (ii) second, 100% to the Non-Voting Members in an amount up to, and in proportion to, the amount of Profits allocated to the Non-Voting Members under Section 8.2.1(ii), (iii) third, 100% to the Voting Members in proportion to their positive Adjusted Capital Account balances until such positive Adjusted Capital Account balances have been reduced to $0, and (iv) fourth, 100% to the Non-Voting Members in proportion to their positive Adjusted Capital Account balances until such positive Adjusted Capital Account balances have been reduced to $0.

     8.2.3. Limitation on Allocations of Losses. The Losses allocated pursuant to Section 8.2.2 to any Member for any Fiscal Year cannot exceed the maximum amount of Losses that may be allocated to such Member without causing such Member to have an Adjusted Capital Account Deficit at the end of such Fiscal Year. All Losses in excess of the limitation in this Section 8.2.3 will be allocated solely to the other Members pursuant to Section 8.2.2.

     8.3. Special Allocations.

     8.3.1. Minimum Gain Chargeback; Company Nonrecourse Liabilities. If there is a net decrease in Company Minimum Gain during any Fiscal Year, certain items of income and gain will be allocated (on a gross basis) to the Members in accordance with the rules described in Regulations sections 1.704-2(f), (j)(2)(i) and (j)(2)(iii), subject to the exemptions set forth in Regulations section l.704-2(f)(2), (3), (4) and (5). This Section 8.3.1 is intended to comply with the “minimum gain chargeback” requirement set forth in Regulations section 1.704-2(f) relating to partnership nonrecourse liabilities (as defined in Regulations section l.704-2(b)(3)) and will be so interpreted.

     8.3.2. Minimum Gain Chargeback; Member Nonrecourse Debt. If there is a net decrease in Member Minimum Gain during any Fiscal Year, certain items of income and gain will be allocated (on a gross basis) as quickly as possible to those Members who had a share of the Member Minimum Gain (determined pursuant to Regulations section l.704-2(i)(5)) in accordance with the rules described in Regulations sections 1.704-2(i)(4), (j)(2)(ii) and (j)(2)(iii). This Section 8.3.2 is intended to comply with the “minimum gain chargeback” requirement set forth in Regulations section 1.704-2(i)(4) relating to Member nonrecourse debt (as defined in Regulations section 1.704-2(b)(4)) and will be so interpreted.

     8.3.3. Qualified Income Offset. If any Member has an Adjusted Capital Account Deficit, items of Company income and gain will be specially allocated (on a gross basis) to the Member in an amount and manner sufficient to eliminate, to the extent required by the Regulations, the Adjusted Capital Account Deficit of the Member as quickly as possible. This Section 8.3.3 is intended to comply with the “qualified income offset” requirement set forth in Regulations section 1.704 l(b)(2)(ii)(b) and will be so interpreted.

     8.3.4. Optional Basis Adjustments. To the extent an adjustment to the adjusted tax basis of any asset of the Company pursuant to Code sections 734(b) or 743(b) is required, pursuant to Regulations section 1.704-l(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of the adjustment to the Capital Accounts will be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis) and such gain or loss shall be specially allocated to the Members in a manner consistent with the manner in which their Capital Accounts are required to be adjusted pursuant to Regulations section 1.704-l(b)(2)(iv)(m).

     8.3.5. Nonrecourse Deductions. Nonrecourse Deductions for any Fiscal Year will be specially allocated among the Members in proportion to their Percentage Interests.

     8.3.6. Member Nonrecourse Deductions. Member Nonrecourse Deductions will be allocated pursuant to Regulations sections 1.704-2(b)(4) and (i)(1) to the Member who bears the economic risk of loss with respect to the deductions.

     8.4. Curative Allocations. The allocations set forth in Section 8.3 (the “Regulatory Allocations”) are intended to comply with certain requirements of the Regulations. It is the intent of the Members that, to the extent possible, all Regulatory Allocations will be offset either with other Regulatory Allocations or with special allocations of other items of Company income, gain, loss, deduction or credit pursuant to this Section 8.4. Therefore, notwithstanding any other provision of this Article 8 (other than with respect to the Regulatory Allocations), the Managers shall make the offsetting special allocations of Company income, gain, loss, deduction or credit in whatever manner it determines appropriate so that, after the offsetting allocations are made, each Member’s Capital Account balance is, to the extent possible, equal to the Capital Account balance the Member would have had if the Regulatory Allocations were not part of this Agreement and all items were allocated pursuant to Section 8.2.

     8.5. Tax Allocations: Code Section 704(c). In accordance with Code section 704(c) and the applicable Regulations promulgated thereunder, income, gain, loss, deduction, credit and tax depreciation with respect to any property contributed to the capital of the Company with a fair market value different from its adjusted tax basis at the time of contribution, or with respect to any property that has an adjusted fair market value different from its adjusted tax basis, shall, solely for income tax purposes, be allocated among the Members so as to take into account any variation between the Company’s adjusted tax basis in the property and the fair market value of the property. Unless otherwise agreed upon by a Super-majority of Managers, the “traditional method” under Section 1.704-3(b)(1) of the Regulations will be elected by the Company to handle any book-tax disparity under Section 704(c) of the Code with respect to any asset, and to

the extent allowable under applicable Regulations, different methods may be used for different assets. In addition, if any gain (as computed for federal income tax purposes) on the sale or other disposition of Company property constitutes recapture of depreciation under Code sections 291, 1245 or 1250 or any similar provision, the gain will (to the extent possible) be divided among the Members in proportion to the depreciation deductions previously claimed by them (or their predecessors in interest) giving rise to the recapture; provided, however, that this sentence will not affect the amount of gain otherwise allocable to a Member.

     8.6. Other Allocation Rules.

     8.6.1. For purposes of determining the Profits and Losses, and such other items will be determined on a daily, monthly or other basis, as determined by the Managers using any permissible method under Code section 706 and the Regulations thereunder.

     8.6.2. For federal income tax purposes, every item of income, gain, loss, deduction and credit will be allocated among the Members in accordance with the allocation provisions of Sections 8.2, 8.3, and 8.4.

     8.6.3. The Members are aware of the income tax consequences of the allocations made by this Article 8 and agree to be bound by the provisions of this Article 8 in reporting their shares of partnership income and loss for income tax purposes.

     8.6.4. It is intended that the allocations in Sections 8.2, 8.3, 8.4, and 8.5 effect an allocation for federal income tax purposes consistent with Code section 704 and comply with any limitations or restrictions therein. The Managers may alter the allocations pursuant to this Article 8 in any manner consistent with Code section 704 and amend the provisions of this Agreement as appropriate to comply with the Regulations promulgated under Code section 704, if, in the opinion of counsel, such an amendment is advisable to reflect allocations among the Members consistent with such Regulations, and such allocation will not have a material effect on the distributions which would otherwise be made pursuant to Article 7 or Article 11.

     8.6.5. The Managers may vary the allocations described in Article 8 and the Capital Accounts of the Members attributable to such allocations to the extent necessary to avoid any double counting of Profits or Losses including, for example, double counting that could occur in the event that there is a Revaluation Event.

     8.7. Changes in Percentage Interests. If a Member’s Percentage Interest changes at any time during a Fiscal Year, then, for purposes of making the allocations required under this Article 8, the Percentage Interests of the relevant Members will be adjusted in accordance with Code section 706 using any reasonable convention determined by the Managers.

     8.8. Treatment of Preferred Return Amount. The Company intends not to treat the accrual of the Preferred Return Amount during each Accounting Period as a “guaranteed payment” by the Company to the Non-Voting Members under Section 707(c) of the Code, but if the Managers believe that the Company is required by law, or if the Internal Revenue Service successfully asserts, that the Preferred Return Amount should be so treated, then (I) the Preferred Return Amount shall be so treated, (II) the Company shall cease making allocations of Profits or

Gain from a Change of Control Transaction to the Non-Voting Members in respect of the Preferred Return Amount under Section 8.2.1(ii), and (III) the Company shall make additional distributions of Tax Distribution Amounts to the Non-Voting Members pursuant to Section 8.2.1(i) in respect of such accrued guaranteed payment amounts to the extent that the aggregate Tax Distribution Amounts (treating the accrual of the Preferred Return Amount as an allocation of taxable income to the holders of the Non-Voting Units as being entitled to a Tax Distribution Amount with respect to such accrual) as redetermined based on such tax treatment, exceeds the aggregate Tax Distribution Amounts previously distributed to the Non-Voting Members pursuant to Section 7.2.1(i) with respect to allocations of income pursuant to Section 8.2.1(ii).

As long as a Person is a Member of the Company, such Member and its Affiliates shall not engage in business activities which are in direct competition with the business of the Company within the state of Oklahoma. The restrictions contained herein are in addition to and not in lieu of any other restrictions contained in any employment agreement which a Member may have with the Company.

     10.7.2. Except as provided in Section 10.7.1, and except with respect to officers or employees of the Company who are also Members, nothing in this Agreement shall be deemed to restrict in any way the rights of any Member, or of any Affiliate of any Member, to conduct any other business or activity whatsoever, and no Member shall be accountable to the Company or to any other Member with respect to that business or activity. The organization of the Company shall be without prejudice to the Members’ (other than officers or employees of the Company) respective rights (or the rights of their respective Affiliates) to maintain, expand, or diversify such other interests and activities

and to receive and enjoy profits or compensation therefrom. Each Member waives any rights the Member might otherwise have to share or participate in such other interests or activities of any other Member or the Member’s Affiliates. Nothing in this Section 10.7.2 shall be deemed to modify in any manner separate noncompetition agreements executed by certain Members for the benefit of the Company.

     10.7.3. Each Member and Manager acknowledges and agrees that the information, observations, trade secrets and data concerning the business and affairs of the Company obtained by them by reason of their membership herein or management hereof (“Confidential Information”) are the property of the Company. Therefore, each Member and Manager agrees that such Member or Manager, as the case may be, shall not disclose to any unauthorized person or use for such Member’s or Manager’s own account any Confidential Information without the prior written consent of the disinterested Managers unless and to the extent that the aforementioned matters (a) become generally known to and available for use by the public other than as a result of such Member’s or Manager’s acts or omissions to act or (b) must be disclosed under a subpoena or other governmental order (but then, only after the Company is given notice of such subpoena or order and the opportunity to seek a protective order).

     (iii) the date sixty (60) calendar days after the Company is not treated as a partnership for federal income tax purposes; provided that the Company uses reasonable efforts to restore its partnership tax status in such sixty (60)-day period, except that no dissolution shall occur pursuant to this clause if treatment

of the Company other than as a partnership for federal income tax purposes occurs as a result of a voluntary election by the Company of such other treatment.

     11.2. Authority to Wind Up. The Managers shall have all necessary power and authority required to marshal the assets of the Company, to pay the Company’s creditors, to establish reasonable reserves for contingent liabilities of the Company, to distribute assets and otherwise wind up the business and affairs of the Company. In particular, the Managers shall have the authority to continue to conduct the business and affairs of the Company insofar as such continued operation remains consistent, in the judgment of the Managers, with the orderly winding up of the Company.

     11.3. Articles of Dissolution; Winding Up. When an event set forth in Section 11.1 occurs, the Company shall file Articles of Dissolution as required by the Act, and shall take whatever other action may be advisable or proper to carry out the liquidation and winding up of the Company.

     11.4. Distribution of Property. Upon dissolution and winding up of the Company, the affairs of the Company shall be wound up and the Company liquidated by the Members.

Each time a Member holding Units (the “Transferring Member”) proposes to transfer all or any portion of the Units held by such Member (or is required to do so by operation of law or other involuntary means), such Member shall first comply with the following provisions and the provisions of this Article 12.

     12.2. Transfer Notice. The Transferring Member shall deliver a written notice (the “Transfer Notice”) to (a) the other Members, and (b) the Company stating (i) the Transferring Member’s bona fide intention to transfer such Units, (ii) the number of Units to be transferred, (iii) the purchase price and terms of payment for which the Transferring Member proposes to transfer such Units and (iv) the name and address of the proposed transferee (the “Proposed Transferee”).

     12.3. Option Period. For a period of thirty (30) Business Days after receipt of the Transfer Notice, the Company shall have the right, but not the obligation, to elect to purchase all or any portion of the Units upon the price and terms of payment designated in the Transfer Notice. If the Transfer Notice provides for the payment of non-cash consideration, the Company

may elect to pay the consideration in cash equal to the good faith estimate of the present fair market value of the non-cash consideration offered as determined by the Managers. Within thirty (30) Business Days after receipt of the Transfer Notice, the Managers on behalf of the Company, to the extent the Company is electing to purchase Units pursuant to this Section 12.3, shall notify the Transferring Member and the non-Transferring Members in writing of the Company’s intent to purchase all or any portion of the Units proposed to be so transferred. The failure of the Company to submit a notice within the applicable period shall constitute an election on the part of the Company not to purchase any of the Units which may be so transferred.

     12.4. Member Purchase. If the Company does not elect to purchase all of the Units proposed to be transferred within the thirty (30)-day period described in Section 12.3, the non-Transferring Members shall have the right, but not the obligation, to elect to purchase any remaining portion of such Units (the “Remaining Units”) upon the price and terms of payment designated in the Transfer Notice. If the Transfer Notice provides for the payment of non-cash consideration, the non-Transferring Members each may elect to pay the consideration in cash equal to the good faith estimate of the present fair market value of the non-cash consideration offered as determined by the Managers. Within fifteen (15) Business Days following the expiration of the thirty (30)-day period described in Section 12.3, each non-Transferring Member electing to purchase the Remaining Units pursuant to this Section 12.4 shall notify the Managers and the Transferring Member in writing of his, her or its desire to purchase a portion of the Remaining Units. The failure of any non-Transferring Member to submit a notice within the applicable period shall constitute an election on the part of that non-Transferring Member not to purchase any of the Remaining Units. The number of Remaining Units that each non-Transferring Member shall be entitled to purchase pursuant to this Section 12.4 shall be determined based upon the proportion that the Percentage Interest of such non-Transferring Member bears to the aggregate of the Percentage Interests of all of the non-Transferring Members electing to purchase the Remaining Units. In the event any non-Transferring Member elects to purchase none or less than all of his, her or its pro rata share of such Remaining Units, then the other non-Transferring Members may elect to purchase more than their pro rata share.

     12.5. Closing of Purchase. If the Company and the non-Transferring Members elect to purchase or obtain any or all of the Units designated in the Transfer Notice, then (a) the closing of such purchase shall occur no later than sixty (60) calendar days after the date of the Transfer Notice and (b) the Transferring Member, the Company and the non-Transferring Members, as applicable, shall execute such documents and instruments and make such deliveries as may be reasonably required to consummate such purchase.

     12.6. Transfer. If the Company and the non-Transferring Members elect not to purchase or obtain, or default in their obligation to purchase or obtain, the Units which they have elected to purchase, then the Transferring Member may transfer any such Units not so purchased to the Proposed Transferee; provided that such transfer (a) is completed within sixty (60) calendar days after the expiration of the Company’s and the non-Transferring Members’ right to purchase such Units (as set forth in Sections 12.3 and 12.4 above), (b) is made on terms not more materially favorable to the Proposed Transferee than as designated in the Transfer Notice, and (c) complies with Section 4.4. If the Units described in the Transfer Notice are not so transferred, the Transferring Member must give notice in accordance with Section 12.2 prior to any other or subsequent transfer of such Units.
