A Member is not entitled to the return of any part of its capital contributions or to be paid interest in respect of either its Capital Account or its capital contributions. An unrepaid capital contribution is not a liability of the Company or of any Member. A Member is not required to contribute or to lend any cash or property to the Company to enable the Company to return any Member’s capital contribution.

Section 5.4. Advances by Members. If the Company does not have sufficient cash to pay its obligations, any Member(s) that may agree to do so may advance all or part of the needed funds to or on behalf of the Company if Member Consent is obtained. An advance described in this Section 5.4 constitutes a loan from the Member to the Company, bears interest at the Prime Rate from the date of the advance until the date of repayment, and is not a capital contribution.

(a) The issuance of any equity security of the Company, the Partnership, Dorchester Operating LP or Dorchester Operating LLC or the issuance of any rights, warrants, options, convertible securities or indebtedness, exchangeable securities or indebtedness or other rights, exercisable for or convertible or exchangeable into any such equity security of the Company, the Partnership, Dorchester Operating LP or Dorchester Operating LLC;

VII. MEETINGS OF THE MEMBERS

Beginning in 2004, an annual meeting of the Members shall be held on March 1 of each year (or the next succeeding business day, if March 1 is not a business day) or at such other time and date as may be determined by Member Consent. The annual meeting shall be held at the Company’s principal office or such other location agreed to by all the Members. At such meeting the Members entitled to vote thereat (i) shall cause the Partnership to nominate the Persons for election by the limited partners of Dorchester Minerals as Independent Managers that are the members of the Advisory Committee as provided in Section 8.2 of this Agreement, (ii) may elect additional Independent Managers, pursuant to Section 8.2 hereof, as are required by Market Rules or if any Appointment Right is lost by any Members as to any Independent Manager pursuant to Section 8.4 hereof, and (iii) may transact such other business as properly may be brought before the meeting and that is within the scope of the permitted decisions specified in Section 6.6 hereof.

Section 7.5. Quorum of Members. Unless otherwise provided by applicable law, the Certificate of Formation or this Agreement, the presence of a majority of the Members on a per capita basis and represented in person or by proxy, shall constitute a quorum at a meeting of the Members.

Section 7.6. Proxies. At any meeting of the Members, each Member having the right to vote shall be entitled to vote either in person or by proxy executed in writing by the Member or by his duly authorized attorney- in- fact.

Section 7.7. Action by Written Consent Without a Meeting and Telephonic Meetings. Any action required or permitted by applicable law, the Certificate of Formation, or this Agreement to be taken at a meeting of the Members may be taken without a meeting, without prior notice, and without a vote, if a consent in writing, setting forth the action so taken, is signed by Members having not less than the minimum number of votes that would be necessary to take such action at a meeting at which Members entitled to vote on the action were present and voting. Any such written consent does not have to be unanimous (unless the action that is approved in such written consent would require the unanimous approval of all Members at a meeting at which all of the Members were present). Every written consent must bear the date of signature of each Member who signs the consent. No written consent shall be effective to take the action that is the subject of the consent unless, within sixty (60) days after the date of the earliest dated consent delivered to the Company in the manner required by this Section 7.7, a consent or consents signed by Members having not less than the minimum number of votes that would be necessary to take the action that is the subject of the consent are delivered to the Company by delivery to its registered office, its principal place of business, or an officer or agent of the Company having custody of the books in which proceedings of meetings of Members are recorded.

With prior Member Consent, Members may participate in and hold a meeting of the Members by conference telephone or similar communications equipment by means of which all Persons participating in the meeting can hear each other, and participation in such a meeting 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.

VIII. BOARD OF MANAGERS

Section 8.1. Powers. The business and affairs of the Company shall be managed by or under the direction of its Board of Managers, which may exercise all such powers of the Company and do all such lawful acts and things as are not by non-waivable provisions of the Act or by the Certificate of Formation or by this Agreement directed or required to be exercised and done by the Members. No individual Manager has the authority to bind the Company unless the Manager is granted such authority by the Board of Managers.

Section 8.2. Number of Managers. The Board of Managers shall consist of (a) five (5) Managers, with each Member appointing one such Manager (collectively, the “Appointed Managers”); and (b) three independent managers (other than the Appointed Managers) or such other, greater number of independent managers (other than the Appointed Managers) as required by the rules and regulations of the market quotation system or securities exchange, as the case may be, on which units of Dorchester Minerals are or are intended to be listed (the “Market Rules”), which independent managers shall meet the requirements for members of the “Advisory Committee” as defined in the Dorchester Minerals Limited Partnership Agreement. The independent managers in clause (b) of the preceding sentence are referred to herein as the “Independent Managers.” No two or more Members may designate the same individual as a Manager to serve on the Board of Managers. The initial Appointed Manager for each Appointing Member shall be as follows:

APPOINTING MEMBER		APPOINTED MANAGER
▇▇▇		▇.▇. ▇▇▇▇▇, ▇▇.
▇▇▇▇▇▇		▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇
SAOG		▇▇▇▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇
Peak ▇▇		▇▇▇▇▇▇▇ A. Peak
▇▇▇▇▇ ▇▇		▇▇▇▇▇ ▇. ▇▇▇▇▇

Peak LP and ▇▇▇▇▇ ▇▇ shall collectively have the right to appoint one (1) Independent Manager to serve as a member of the Advisory Committee until the 2004 annual meeting of limited partners of Dorchester Minerals (the “Peak LP/▇▇▇▇▇ ▇▇ Appointment Right”). ▇▇▇▇▇▇ shall have the right to appoint one (1) Independent Manager to serve as a member of the Advisory Committee until the 2004 annual meeting of limited partners of Dorchester Minerals (the

“▇▇▇▇▇▇ Appointment Right”). ▇▇▇ and SAOG shall collectively have the right to appoint one (1) Independent Manager to serve as a member of the Advisory Committee until the 2004 annual meeting of limited partners of Dorchester Minerals (the “▇▇▇/SAOG Appointment Right”). (Such rights are referred to herein collectively as the “Appointment Rights.”) Beginning with the annual meeting of limited partners of Dorchester Minerals in 2004, each of the Appointment Rights shall be the right to cause the Partnership to nominate one (1) Person for election, in accordance with the Dorchester Minerals Limited Partnership Agreement, by the limited partners of Dorchester Minerals as an Independent Manager that is a member of the Advisory Committee. Each person so elected by the limited partners of Dorchester Minerals shall, as a result of such election, be an Independent Manager of the Company. Such nominations shall be made by the holders of the Appointment Rights at the annual meeting of Members as provided by Section 7.1. If any additional Independent Managers are required by the Market Rules or if any such Appointment Right is lost by any Members as to any Independent Managers pursuant to Section 8.4, such Independent Managers shall be elected or nominated, as applicable, by a vote of the majority of the Members. Each such Independent Manager shall meet the requirements for independent directors set forth in the Market Rules.

Section 8.3. Election and Term.

(a) Each Appointed Manager shall serve until the earlier of his death, resignation or removal from office which may be with or without cause by the Member that appointed such Manager (the “Appointing Member”). In the event of a vacancy on the Board of Managers (other than a vacancy which must be filled with an Independent Manager), then the Appointing Member that appointed the Appointed Manager whose failure to continue to serve as a Manager has created the vacancy shall fill such vacancy by delivery of written notice to the Company and each other Member designating a replacement Manager to fill such vacancy (or, if such appointment right has been lost pursuant to Section 8.4, such vacancy shall be filled by majority vote of the Members specified in Section 8.4). Upon receipt of such written notice by the Company, the replacement Appointed Manager shall be appointed as a Manager hereunder, unless objected to in writing on a reasonable basis by all of the Appointed Managers other than the Manager who is being replaced pursuant to this Section 8.3(a) and any Manager whose Appointing Member, or an Affiliate thereof, has the appointment right with respect to such replacement.

(b) Each appointed Independent Manager that is a member of the Advisory Committee shall hold office until the 2004 annual meeting of limited partners of Dorchester Minerals, unless such appointed Independent Manager shall sooner cease to serve as a result of his death, resignation or removal. Beginning with the 2004 annual meeting of limited partners of Dorchester Minerals, each Person elected by the limited partners of Dorchester Minerals as an Independent Manager that is a member of the Advisory Committee shall hold office until the next annual meeting of limited partners of Dorchester Minerals in accordance with the Dorchester Minerals Limited Partnership Agreement. Any Independent Manager elected by the Members pursuant to Section 7.1 that is not required to be elected by the limited partners of Dorchester Minerals as a member of the Advisory Committee shall serve until the next annual meeting of Members, unless such Independent Manager shall sooner cease to serve as a result of his death, resignation or removal. In the event of a vacancy on the Board of Managers which must be filled with an Independent Manager that is a member of the Advisory Committee, such

vacancy shall be filled by written notice to the Company and each Member given by the Member or Members having the Appointment Right with respect to the Independent Manager whose death, resignation or removal necessitated the appointment of a replacement Independent Manager (or, if such Appointment Right has been lost pursuant to Section 8.4, such vacancy shall be filled by majority vote of the Members specified in Section 8.4). Upon receipt of such written notice by the Company, the replacement Independent Manager shall be appointed as an Independent Manager hereunder, unless objected to in writing on a reasonable basis by all of the Appointed Managers other than any Manager whose Appointing Member, or an Affiliate thereof, has or shares the Appointment Right with respect to the replacement Independent Manager.

Section 8.4. Loss of Appointment Right. If at any time after the Effective Date a Change in Control of any Member occurs, then such Member shall lose all appointment and removal rights stated in Sections 8.2 and 8.3 unless and until the other Members unanimously consent to the continuation of such Member’s appointment and removal rights following such Change in Control. In the event that a Member loses appointment and removal rights in accordance with this Section 8.4, then the remainder of the Members shall exercise such Member’s appointment and removal rights by majority vote; provided, that no Manager appointed pursuant to such rights may concurrently be serving as either an Appointed Manager or an Independent Manager. Notwithstanding the foregoing, if either of the Members sharing a particular Appointment Right (but not both) experience a Change in Control, such Appointment Right shall be solely vested in the Member, if any, which did not experience a Change in Control. In the event that both of the Members sharing a particular Appointment Right lose their appointment and removal rights in accordance with this Section 8.4, such Appointment Right shall immediately expire. A Change in Control of a Member shall not affect the right of that Member to vote on all matters on which Members are entitled to vote by law or under this Agreement or on any other matter presented to a vote of the Members, including without limitation, any vote that could in any way adversely affect such Member’s interest in the capital or profits of the Company or of the Partnership.

Section 8.5. Resignation and Removal. Any Manager may resign at any time upon giving written notice to the Company. Any Appointed Manager or any Independent Manager appointed pursuant to an Appointment Right may be removed only by his Appointing Member, or the Member or Members having the Appointment Right with respect to such Independent Manager (as applicable), in accordance with Section 8.3. Any other Independent Manager may be removed at any time with or without cause by the vote of two-thirds (2/3) of the Members.

Section 8.6. Compensation of Managers. The Managers may be paid their expenses of attendance at each meeting of the Board of Managers; however, Appointed Managers shall not receive any compensation for serving as a Manager or as a member of any committee of the Board of Managers. The Independent Managers shall be compensated in such amounts as shall be established by the Appointed Managers. This provision shall not preclude any Manager from serving the Company in any other capacity and receiving compensation therefor. In addition to the foregoing, all expenses incurred by a Manager in the performance of its duties hereunder or for and on behalf of the Company in connection with the business of the Company (including,

without limitation, charges for legal, accounting, data processing, administrative, executive, tax and other services rendered by employees of any Manager) will be paid or promptly reimbursed by the Company; provided, however, that any salary or compensation expense incurred by a Manager and attributable to the provision by the Manager of the services of its officers in connection with the business of the Company hereunder shall not be reimbursed to such Manager but the actual out-of-pocket expenses incurred by the Manager (other than salary or compensation expense) with respect to such provision of the services or its officers hereunder shall be reimbursed by the Company.

Section 8.7. Chairman of the Board of Managers. The Board may, but shall not be required to, from time to time, by majority vote designate one Manager to serve as Chairman of the Board of Managers; provided, however, that any such Chairman of the Board of Managers shall not, in such capacity, be an officer of the Company. The Chairman of the Board of Managers shall preside at all meetings of the Board of Managers and shall have such other powers and duties as usually pertain to such position or as may be delegated to him by the Board of Managers. The Chairman of the Board of Managers shall serve as such until the earlier of his death, resignation or removal from office by the Board of Managers.

XII. INDEMNIFICATION

Section 12.1. Right to Indemnification. Subject to the limitations and conditions set forth in this Article XII, each Person who was or is made a party or is threatened to be made a party to or is involved in any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative, arbitrative or investigative (a “Proceeding”), or any appeal in such a Proceeding or any inquiry or investigation that could lead to such a Proceeding, by reason of the fact that he or she, or a Person of whom he or she is the legal representative, is or was a Member, Manager or officer of the Company or while a Member, Manager or officer of the Company is or was serving at the request of the Company as a partner, director, officer, manager, member, venturer, proprietor, trustee, employee, agent, or similar functionary of another foreign or domestic limited liability company, corporation, partnership, joint venture, sole proprietorship, trust, employee benefit plan or other enterprise (a “Covered Person”), shall be indemnified by the Company to the fullest extent permitted by the Act, as the same exists or may be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Company to provide broader indemnification rights than said law permitted the Company to provide prior to such amendment) against judgments, penalties (including excise and similar taxes and punitive damages), fines, settlements and reasonable expenses (including, without limitation, attorneys’ fees) actually incurred by such Person in connection with such Proceeding, and indemnification under this Section 12.1 shall continue as

to a Person who has ceased to serve in the capacity that initially entitled such Person to indemnity under this Section. Such actions covered by such indemnification shall include those brought by a Member or the Company. The rights granted pursuant to this Article XII shall be deemed contract rights, and no amendment, modification or repeal of this Article XII shall have the effect of limiting or denying any such rights with respect to actions taken or Proceedings arising prior to any such amendment, modification or repeal. IT IS EXPRESSLY ACKNOWLEDGED THAT THE INDEMNIFICATION PROVIDED IN THIS ARTICLE XII COULD INVOLVE INDEMNIFICATION FOR NEGLIGENCE OR UNDER THEORIES OF STRICT LIABILITY; provided, however, that notwithstanding the foregoing or any other provision of this Agreement, the Company shall not provide indemnification to any Person in respect of any Disabling Conduct. The negative disposition of any Proceeding by judgment, order, settlement, conviction or upon a plea of nolo contendere, or its equivalent, shall not, of itself, create a presumption that the Covered Person acted in a manner contrary to the standard set forth in this Section.

Section 12.2. Advance of Expenses. The right to indemnification conferred in this Article XII shall include the right to be paid or reimbursed by the Company the reasonable expenses incurred by a Person of the type entitled to be indemnified under Section 12.1 or 12.3 who was, is or is threatened to be made a named defendant or respondent in a Proceeding in advance of the final disposition of the Proceeding and without any determination as to the Person’s ultimate entitlement to indemnification; provided, however, that the payment of such expenses incurred by any such Person in advance of the final disposition of a Proceeding shall be made only upon the delivery to the Company of a written affirmation by such Person of his good faith belief that he has met the standard of conduct necessary for indemnification under Section 12.1 or 12.3 and a written undertaking, by or on behalf of such Person, to repay all amounts so advanced if it shall ultimately be determined that such indemnified Person is not entitled to be indemnified under Section 12.1 or 12.3.

Section 12.3. Indemnification of Employees and Agents. The Company may indemnify and advance expenses to any employee or agent of the Company to the same extent permitted under Section 12.1 for Covered Persons. In addition, the Company may (by a resolution of the Members) indemnify and advance expenses to any Person whether or not he is an employee or agent of the Company but who is or was serving at the request of the Company as a manager, director, officer, partner, venturer, proprietor, trustee, employee, agent or similar functionary of another foreign or domestic limited liability company, corporation, partnership, joint venture, sole proprietorship, trust, employee benefit plan or other enterprise against any liability asserted against him and incurred by him in such a capacity or arising out of his status as such a Person, to the same extent permitted under Section 12.1 for Covered Persons.

Section 12.4. Appearance as a Witness. Notwithstanding any other provision of this Article XII the Company may pay or reimburse expenses incurred by a Member, Manager, officer, employee or agent in connection with his appearance as a witness or other participation in a Proceeding at a time when he is not a named defendant or respondent in the Proceeding.

Section 12.5. Non-Exclusivity of Rights. The right to indemnification and the advancement and payment of expenses conferred in this Article XII shall not be exclusive of any other right a Person indemnified pursuant to this Article XII may have or may acquire under any

law (common or statutory), any provision of the Certificate or this Agreement, a vote of Members or Managers or otherwise.

Section 12.6. Insurance. The Company may purchase and maintain insurance, to the extent and in such amounts as the Board of Managers shall, in its sole discretion, deem reasonable, to protect itself, the Partnership, Dorchester Operating LP and/or Dorchester Operating LLC, and/or any Covered Persons or other Persons indemnifiable under the provisions of this Article XII. against any expense, liability or loss, whether or not the Company would have the power to indemnify such Person against such expenses, liability or loss under this Article XII.

Section 12.7. Member Notification. To the extent required by law, any indemnification of or advance of expenses to a Person in accordance with this Article XII shall be reported in writing to the Members within the thirty (30)-day period immediately following the date of the indemnification or advance.

Section 12.8. No Personal Liability. In no event may any Covered Person subject the Members to personal liability by reason of any indemnification of an Covered Person under this Agreement or otherwise.

Section 12.9. Interest in Transaction. A Covered Person shall not be denied indemnification in whole or in part under this Article XII because the Covered Person had an interest in the transaction with respect to which the indemnification applies if the transaction is otherwise permitted by the terms of the Governance Agreements.

Section 12.10. Successors and Assigns. The provisions of this Article XII are for the benefit of the Covered Persons and their heirs, successors, assigns, administrators and personal representatives and shall not be deemed to be for the benefit of any other Persons. The provisions of this Section 12.10 shall not be amended in any way that would diminish the rights of Covered Persons under this Article XII without the consent of all Members.

Section 12.11. Savings Clause. If all or any portion of this Article XII shall be invalidated on any ground by any court of competent jurisdiction, then the Company shall nevertheless indemnify and hold harmless any Person indemnified pursuant to this Article XII as to costs, charges and expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement with respect to any action, suit or proceeding, whether civil, criminal, administrative or investigative, to the fullest extent permitted by any applicable portion of this Article XII that shall not have been invalidated and, subject to this Article XII, to the fullest extent permitted by applicable law.

Section 12.12. Exculpation. The following exculpatory provisions shall apply to this Agreement:

(a) General. Notwithstanding any other terms of this Agreement, whether express or implied, or obligation or duty at law or in equity, no Covered Person nor any officer, employee, representative or agent of the Company or its Affiliates shall be liable to the Company or any Member for any act or omission (in relation to the Company, this Agreement, any related document or any transaction or investment contemplated hereby

or thereby) taken or omitted in good faith by such Person and in the reasonable belief that such act or omission is in or is not contrary to the best interests of the Company and is within the scope of authority granted to such Person by this Agreement or the other Governance Agreements except in the following circumstances: (i) such act or omission constitutes Disabling Conduct or (ii) with respect to liability that may arise under any other agreement, such act or omission constitutes a breach of that agreement.

(b) Reliance. A Covered Person or other officer, employee, representative or agent of the Company may rely and shall incur no liability in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, debenture, paper, document, signature or writing reasonably believed by it to be genuine, and may rely on a certificate signed by an officer of any Person in order to ascertain any fact with respect to such Person or within such Person’s knowledge and may rely on an opinion of counsel selected by such Covered Person or other officer, employee, representative or agent of the Company with respect to legal matters unless such Covered Person acts in bad faith.

XIII. ALLOCATIONS

Section 13.1. Consent to Allocations. Each Member as a condition of becoming a Member expressly consents to the following allocations as set forth in this Article XIII.

Section 13.2. Distributive Shares for Tax Purposes. There shall be allocated to each Member for federal income tax purposes a separate distributive share of all Company income, gain, loss, deduction and credit as follows:

(a) Except as otherwise provided in this Article XIII, Net Profit, if any, of the Company (and each item thereof) for each Fiscal Year or other period shall be allocated among the Members pro rata in accordance with their Ownership Percentages.

(b) Except as otherwise provided in this Article XIII, Net Loss, if any, of the Company (and each item thereof) for each Fiscal Year or other period shall be allocated to the Members pro rata in accordance with their Ownership Percentages.

(c) The provisions of this Agreement relating to the allocation of Gross Income, Net Profit and Net Loss are intended to comply with the Treasury Regulations under Section 704(b) of the Code and shall be interpreted and applied in a manner consistent with such Treasury Regulations.

(d) Notwithstanding any other provision of this Agreement to the contrary, if in any Fiscal Year or other period there is a net decrease in the amount of the Company Minimum Gain, then each Member shall first be allocated items of Gross Income for such year (and, if necessary, subsequent years) in an amount equal to such Member’s share of the net decrease in such minimum gain during such year (as determined under Treasury Regulations Section 1.704-2(g)(2)); provided, however, if there is insufficient Gross Income in a year to make the allocation specified above for all Members for such year, the Gross Income shall be allocated among the Members in proportion to the

respective amounts they would have been allocated above had there been an unlimited amount of Gross Income for such year.

(e) Notwithstanding any other provision of this Agreement to the contrary other than Section 13.2(d), if in any year there is a net decrease in the amount of the Member Nonrecourse Debt Minimum Gain, then each Member shall first be allocated items of Gross Income for such year (and, if necessary, subsequent years) in an amount equal to such Member’s share of the net decrease in such minimum gain during such year (as determined under Treasury Regulations Section 1.704-2(i)(4)); provided, however, if there is insufficient Gross Income in a Fiscal Year to make the allocation specified above for all Members for such year, the Gross Income shall be allocated among the Members in proportion to the respective amounts they would have been allocated had there been an unlimited amount of Gross Income for such Fiscal Year.

(f) Notwithstanding any other provision of this Agreement to the contrary (except Sections 13.2(d) and 13.2(e) which shall be applied first), if in any Fiscal Year or other period a Member unexpectedly receives an adjustment, allocation or distribution described in Treasury Regulations Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6), items of Gross Income shall first be allocated to Members with negative Capital Account balances (adjusted in accordance with Section 13.4(e)), in proportion to such negative balances, until such balances are increased to zero.

(g) Notwithstanding the provisions of Section 13.2(b), Net Loss (or items thereof) shall not be allocated to a Member if such allocation would cause or increase a negative balance in such Member’s Capital Account (adjusted in accordance with Section 13.4(e)) and shall be reallocated to the other Members, subject to the limitations of this Section 13.2(g).

(h) Any Member Nonrecourse Deductions shall be allocated to the Member who bears the economic risk of loss with respect to the Member Nonrecourse Debt to which such deductions are attributable.

(i) Company Nonrecourse Deductions shall be allocated to the Members pro rata in accordance with their Ownership Percentages.

(j) In the event that any Gross Income, Net Loss (or items thereof) or deductions are allocated pursuant to Sections 13.2(d) through 13.2(i), subsequent Gross Income, Net Profit or Net Loss (or items thereof) will first be allocated (subject to Sections 13.2(d) through 13.2(i)) to the Members in a manner which will result in each Member having a Capital Account balance equal to that which would have resulted had the original allocation of Gross Income, Net Loss (or items thereof) or deductions pursuant to Sections 13.2(d) through 13.2(i) not occurred; provided, however, no allocations pursuant to this Section 13.2(j), which are intended to offset allocations pursuant to Section 13.2(h) and Section 13.2(i), shall be made prior to the Fiscal Year during which there is a net decrease in Member Nonrecourse Debt Minimum Gain or Company Minimum Gain, and then only to the extent necessary to avoid any potential economic distortions caused by such net decrease in Member Nonrecourse Debt

Minimum Gain or Company Minimum Gain, and no such allocation pursuant to this Section 13.2(j) shall be made to the extent that the Board of Managers reasonably determines that it is likely to duplicate a subsequent mandatory allocation pursuant to Section 13.2(d) or Section 13.2(e).

(k) Unless the Board of Managers elects to adjust Capital Accounts to reflect Actual Depletion Deductions pursuant to Section 1.704-1(b)(2)(iv)(k)(3) of the Treasury Regulations, the portion of the total amount realized by the Company upon the taxable disposition of a Depletable Property that represents recovery of its simulated adjusted tax basis therein will be allocated to the Members in the same proportion as the aggregate adjusted tax basis of such property was allocated to such Members (or their predecessors in interest). If the Board of Managers elects to use Actual Depletion Deductions pursuant to Section 1.704-1(b)(2)(iv)(k)(3) of the Treasury Regulations, the portion of the total amount realized by the Company upon a taxable disposition of such property that equals the Members’ aggregate remaining adjusted basis therein will be allocated to the Members in proportion to their respective remaining adjusted tax bases in such property. Any amount realized in excess of the above amounts shall be allocated among the Members in accordance with their Ownership Percentages.

(l) If an interest in the Company is transferred, the Gross Income, Net Profit or Net Loss allocable to the holder of such Company interest for the then Fiscal Year shall be allocated proportionately between the assignor and the assignee based on the number of calendar days during such Fiscal Year for which each party was the owner of the transferred interest in the Company or upon some other reasonable method.

Section 13.3. Code Section 704(c). In accordance with Code Section 704(c) and the Treasury Regulations thereunder, depletion, depreciation, amortization, income, gain and loss, as determined for tax purposes, with respect to any property whose Book Value differs from its adjusted basis for federal income tax purposes shall, for tax purposes, be allocated among the Members so as to take account of any variation between the adjusted basis of such property to the Company for federal income tax purposes and its Book Value. The Company shall utilize such method to eliminate book-tax disparities attributable to a contributed property or adjusted property as shall be determined by the Board of Managers. Allocations pursuant to this Section 13.3 are solely for purposes of federal, state, and local taxes and shall not affect, or in any way be taken into account in computing, any Member’s Capital Account or share of Net Profit, Net Loss, other items, or distributions pursuant to any provision of this Agreement.

Section 13.4. Capital Accounts. A separate capital account (“Capital Account”) shall be maintained for each Member, as follows:

(a) There shall be credited to each Member’s Capital Account the amount of any cash actually contributed by such Member to the capital of the Company (or deemed contributed pursuant to Treasury Regulations Section 1.704-1(b)(2)(iv)(c)), the fair market value of any property contributed by such Member to the capital of the Company (net of any liabilities secured by such property that the Company is considered to assume or to take subject to under Code Section 752), such Member’s share of the Gross Income and Net Profit (and all items thereof) of the Company and such Member’s share of

Simulated Gain or, if the Board of Managers elects to use Actual Depletion Deductions pursuant to Section 1.704-1(b)(2)(iv)(k)(3) of the Treasury Regulations, such Member’s Actual Gains. There shall be charged against each Member’s Capital Account the amount of all cash distributed to such Member by the Company (or deemed distributed pursuant to Treasury Regulations Section 1.704-1(b) (2) (iv) (c)), the fair market value of any property distributed to such Member by the Company (net of any liability secured by such property that the Member is considered to assume or take subject to under Code Section 752), such Member’s share of the Net Loss (and all items thereof) of the Company and either such Member’s distributive share of Simulated Losses and Simulated Depletion Deductions or, if the Board of Managers elects to use Actual Depletion Deductions pursuant to Section 1.704-1(b)(2)(iv)(k)(3) of the Treasury Regulations, such Member’s Actual Losses and Actual Depletion Deductions.

(b) If the Company at any time distributes any of its assets in-kind to any Member, the Capital Account of each Member shall be adjusted to account for that Member’s allocable share (as determined under this Article XIII) of the Net Profit or Net Loss that would have been realized by the Company had it sold the assets that were distributed at their respective fair market values immediately prior to their distribution, but only to the extent not previously reflected in the Members’ Capital Accounts.

(c) Any adjustments to the tax basis (or Book Value) of Company property under Code Sections 732, 734 or 743 will be reflected as adjustments to the Capital Accounts of the Members, only in the manner and to the extent provided in Treasury Regulations Section 1.704-1(b)(2)(iv)(m).

(d) Upon the decision of the Board of Managers, the Capital Accounts of the Members shall be adjusted to reflect a revaluation of Company property to its fair market value on the date of adjustment upon the occurrence of any of the following events:

(i) An increase in any new or existing Member’s Ownership Interest resulting from the contribution of money or property by such Member to the Company,

(ii) Any reduction in a Member’s Ownership Interest resulting from a distribution to such Member in redemption of all or part of its Ownership Interest, unless such distribution is pro rata to all Members in accordance with their respective Ownership Interests, and

(iii) Whenever otherwise allowed under Treasury Regulations Section 1.704-1(b)(2)(iv)(f).

The adjustments to Capital Accounts shall reflect the manner in which the unrealized Net Profit or Net Loss inherent in the property would be allocated if there were a disposition of the Company’s property at its fair market value on the date of adjustment.

(e) For purposes of Sections 13.2(d) through 13.2(i) a Member’s Capital Account shall be reduced by the net adjustments, allocations and distributions described

in Treasury Regulations Sections 1.704-1(b)(2)(ii)(d)(4), (5) and (6) which, as of the end of the Company’s taxable year are reasonably expected to be made to such Member, and shall be increased by the sum of (i) any amount which the Member is required to restore to the Company upon liquidation of its Ownership Interest in the Company (or which is so treated pursuant to Treasury Regulations Section 1.704-1(b)(2)(ii)(c)) pursuant to the terms of this Agreement or under state law, (ii) the Member’s share (as determined under Treasury Regulations Section 1.704-2(g)(1)) of Company Minimum Gain, (iii) the Member’s share (as determined under Treasury Regulations Section 1.704-2(i)(5)) of Member Nonrecourse Debt Minimum Gain and (iv) the Member’s share (as determined under Section 752 of the Code) of any recourse indebtedness of the Company to the extent that such indebtedness could not be repaid out of the Company’s assets if all of the Company’s assets were sold at their respective Book Values as of the end of the Fiscal Year or other period and the proceeds from the sales were used to pay the Company’s liabilities. For the purposes of clause (iv) above, the amounts computed pursuant to clause (i) above for each Member shall be considered to be proceeds from the sale of the assets of the Company to the extent such amounts would be available to satisfy (directly or indirectly) the indebtedness specified in clause (iv).

(f) For purposes of computing the Members’ Capital Accounts, Simulated Depletion Deductions, and Simulated Losses shall be allocated among the Members in the same proportions as they (or their predecessors in interest) were allocated the basis of Partnership oil and gas properties pursuant to Code Section 613A(c)(7)(D), the Treasury Regulations thereunder, and Section 1.704-1(b)(4)(v) of the Treasury Regulations. Simulated Gains shall be allocated among the Partners in accordance with their Ownership Percentages. In accordance with Code Section 613A(c)(7)(D) and the Treasury Regulations thereunder and Section 1.704-1(b)(4)(v) of the Treasury Regulations, the adjusted basis of all oil and gas properties shall be shared by the Members in proportion to the Ownership Percentages.

(g) It is the intention of the Members that the Capital Accounts of the Company be maintained strictly in accordance with the Capital Account maintenance requirements of Treasury Regulations Section 1.704-1(b). The foregoing provisions and the other provisions of this Agreement relating to the maintenance of Capital Accounts are intended to comply with Treasury Regulations Section 1.704-1(b), and shall be interpreted and applied in a manner consistent with such regulations and any amendment or successor provision thereto. The Members agree to make any appropriate modifications if events might otherwise cause this Agreement not to comply with Treasury Regulations Section 1.704-1(b).

(h) A deficit in a Member’s Capital Account shall not be considered an asset of the Company, and no Member shall be obligated to restore or otherwise be responsible for a deficit or negative balance in such Member’s Capital Account.

Section 13.5. Compliance with the Code. It is intended that the tax allocations in this Article XII effect an allocation for federal income tax purposes in a manner consistent with Sections 704 and 706 of the Code and comply with any limitations or restrictions therein. The Board of Managers shall have complete discretion to make the allocations pursuant to this

Article XII and the allocations and adjustments to Capital Accounts in any manner consistent with Sections 704 and 706 of the Code.

XIV. DISTRIBUTIONS

Section 14.1. “Net Cash Flow” Defined. The term “Net Cash Flow” for any fiscal period shall mean all Company cash revenues resulting from the Company’s business less the amount of all expenses, reserves and obligations of the Company (including, without limitation, expenses and obligations to which the assets of the Company are subject even if the expense or obligation was not originally incurred by the Company or assumed by the Company) plus the proceeds of sale (principal and interest), refinancing, condemnation, insurance, or otherwise, less the amount of all expenses and obligations of the Company relating thereto (including, without limitation, expenses and obligations to which the assets of the Company are subject even if the expense or obligation was not originally incurred by the Company or assumed by the Company).

Section 14.2. Distribution of Net Cash Flow. Except as provided in Article XVII, and subject to the last sentence of Section 8.4, Net Cash Flow, if any, shall be distributed to the Members pro rata in accordance with their Ownership Percentages at such time or times as determined by the Board of Managers.

Section 14.3. Amount Withheld. Notwithstanding any other provision of this Agreement to the contrary, the Board of Managers is authorized to take any action that it determines to be necessary or appropriate to cause the Company to comply with any withholding or other payment requirements established under the Code or any other federal, state or local law including, without limitation, pursuant to Sections 1441, 1442, 1445 and 1446 of the Code. To the extent that the Company is required to pay to any governmental authority any amount resulting from either the allocation of income or gain or a distribution to any Member (including, without limitation, by reason of Sections 1441, 1442, 1445 or 1446 of the Code), the amount so paid shall be treated as a distribution of cash to the Member and any future distributions to which such Member is entitled shall be reduced to the extent of any amount treated as a distribution pursuant to this Section 14.3. The Capital Account of the Member for which amounts are paid over to a governmental authority pursuant to this Section 14.3 shall be decreased by such amount paid over to the governmental authority. A Member who has had amounts paid over to a governmental authority pursuant to this Section 14.3 shall be entitled to receive any refund of any such tax, penalty, interest or other amount received by the Company on account of amounts paid on behalf of the Member pursuant to this Section 14.3; provided, however, that the amount due such Member shall be reduced by any expenses of the Company incurred in connection with the payment or refund of such tax, penalty, interest or other amount. The Company shall have no duty or obligation to seek to obtain or collect any refund or expend any amount to reduce the amount of any withholding, penalty, interest or other amount otherwise payable to any governmental authority; however, upon request by a Member, the Company shall take reasonable steps to cooperate with the Member on a refund request provided that the Company is reimbursed by the Member for the Company’s costs and expenses arising from such cooperation. If at any time a Member’s interest in the Company is transferred or assigned, the proposed assignee shall certify to non-foreign status prior to the transfer or assignment of the interest. Such certifications shall be made on a form to be provided by the Board of Managers. Each Member shall notify the Company if it becomes either a “Foreign Person”, as defined in Code

Section 1445, or a “Foreign Partner”, as defined in Code Section 1446, within thirty (30) calendar days of such change.

XV. TRANSFER OF INTERESTS

Section 15.1. Transfer Restriction Agreement. Each Member as of the date of this Agreement is also a party to the Transfer Restriction Agreement. As a condition to being admitted as a Member, any other Person must become a party to the Transfer Restriction Agreement, in accordance with the procedures set forth therein. The Transfer Restriction Agreement, a copy of which is attached hereto as Exhibit A, is incorporated by reference in this Agreement as if fully set forth herein and forms a part of this Agreement.

Section 15.2. Transfers of Interests and Admission of New Members. No Member may assign, sell or otherwise transfer by operation of law or otherwise, any of its right, title or interest or any portion thereof in the Company unless such Member shall first comply with the provisions of the Transfer Restriction Agreement applicable to the proposed assignment, sale or transfer. In the event an Affiliate Transfer or a Familial Transfer results in the entirety of a Member’s Ownership Interest in the Company being transferred, then (subject to such transferee’s joining in this Agreement as provided below) such transferee shall be substituted for that Member automatically upon such transfer without the consent of the Members, and shall have all the rights of such Member under this Agreement. In the event of an Affiliate Transfer or a Familial Transfer of the entirety of a Member’s Ownership Interest divided between or among more than one transferee, only one such transferee may become a substituted Member and the remainder of such transferees shall be treated as and have the rights of assignees under the Act. The transferor shall designate in a written notice to the Company and to each other Member which such transferee shall become the substituted Member, and such designated transferee shall (subject to such transferee’s joining in this Agreement as provided below) be substituted for the transferor Member automatically upon such transfer without the consent of the Members with respect to the Ownership Interest transferred to such transferee, and shall have all the rights of such transferring Member under this Agreement. In the event of an Affiliate Transfer or a Familial Transfer of less than the entirety of a Member’s Ownership Interest, such transferee shall not be a substituted Member; but the transferring Member shall remain a Member and retain all rights as a Member under this Agreement. Any other transferee of a Member’s Ownership Interest in the Company shall be admitted to the Company as a substituted Member only if (i) the assignment, sale or other transfer pursuant to which the transferee acquired such Ownership Interest was effected in accordance with the Transfer Restriction Agreement and (ii) “Holder Consent” (as defined in the Transfer Restriction Agreement) of such assignment sale or other transfer has been obtained. If such a transferee is not admitted as a substituted Member under this Article XV, it shall have none of the powers of a Member hereunder but shall, subject to the further provisions hereof, have only such rights of an assignee under the Act as are consistent with this Agreement. Such assignee shall have no voting rights or consent rights (and shall have no power to elect Managers) or any other power to participate in the management of the Company, but shall be subject to the provisions of the Transfer Restriction Agreement including, without limitation, the obligations under Articles II, IV and V thereof, but shall not be entitled to exercise the rights of a party thereto, including, without limitation, under Article III or VI thereof. In the event of any permitted transfer of an interest in the Company pursuant to this Article XV and the Transfer Restriction Agreement, the interest so transferred shall remain

subject to all terms and provisions of this Agreement and the Transfer Restriction Agreement, and the transferee shall be deemed, by accepting the interest so transferred, to have assumed all the liabilities and unperformed obligations, under this Agreement, the Transfer Restriction Agreement or otherwise, which are appurtenant to the interest so transferred; shall hold such interest subject to all unperformed obligations of the transferor Member hereunder and under the Transfer Restriction Agreement; and shall agree in writing to the foregoing if requested by the Board of Managers or the Members and shall join in and be bound by the terms of this Agreement. No assignment shall relieve the assignor from its obligations prior to this Agreement or the Transfer Restriction Agreement, except that if the transferee is admitted as a Member, the assignor shall be relieved of obligations hereunder and under the Transfer Restriction Agreement accruing after the admission of the transferee as a Member.

Section 15.3. Securities Laws Restrictions. Notwithstanding any other provision of this Article XV, no transfer of an interest in the Company may be made if the transfer would violate federal or state securities laws.

Section 16.2. Inspection. All of the books of account of the Company, together with an executed copy of this Agreement and any amendments hereto, shall at all times be maintained at the principal office of the Company and shall be open to the inspection and examination of the Members or their representatives.

In addition, the Board of Managers shall cause to be delivered to all the Members monthly unaudited statements of profit and loss prepared on a cash basis, such statements to reflect profit and loss on both a monthly and year-to-date basis. Each such monthly statement shall be so delivered within sixty (60) days after the end of the month to which the statement pertains. An accounting of all items of receipt, income, profit, cost, expense and loss shall also be prepared made by the Board of Managers upon the dissolution of the Company.

Section 16.5. Tax Returns. The Company shall cause all income tax returns to be prepared or reviewed in compliance with this Agreement (in particular the tax allocations in Article XIII hereof) by such firm of independent certified public accountants as shall be selected by the Board of Managers, shall cause such tax returns to be timely filed with the appropriate authorities and shall cause copies thereof and all related matters needed by any Member for the preparation of its tax returns to be promptly delivered to all Members. Copies of such tax returns shall be kept at the principal office of the Company and shall be available for inspection by any Member during normal business hours. The income tax documentation to be generated hereunder shall include any additional information reasonably requested by a Member for the preparation of its return.

Section 16.6. Tax Elections.

(a) In the event of a transfer of all or part of an interest of a Member authorized by this Agreement, the Company shall, upon the request of the transferee, elect pursuant to Section 754 of the Code to adjust the basis of Company property, and any basis adjustment relating to such transfer, whether made under Section 754 of the Code or otherwise, shall be allocated solely to the transferee; provided, however, that each transferee shall pay the additional bookkeeping and accounting costs which result from the basis adjustment pertaining to such transferee. Each of the Members shall supply to the Company upon request the information necessary properly to give effect to such election.

(b) All other federal income tax elections required or permitted to be made by the Company shall be made in such manner as may be agreed upon by the Board of Managers. No Member shall take any action or refuse to take any action which would cause the Company to forfeit the benefits of any tax election previously made or agreed to be made.

Section 16.7. Tax Matters Partner. ▇▇▇ is hereby designated as the “Tax Matters Partner” of the Company within the meaning of Section 6231(a)(7) of the Code and shall have the power to manage and control, on behalf of the Company, any administrative proceeding at the Company level with the Internal Revenue Service relating to the determination of any item of Company income, gain, loss, deduction, or credit for federal income-tax purposes. The Tax Matters Partner shall comply with all statutory provisions of the Code applicable to a “tax matters partner” and shall, without limitation, within thirty (30) calendar days of the receipt of any notice from the Internal Revenue Service in any administrative proceeding at the Company level relating to the determination of any Company item of income, gain, loss, deduction, or credit, mail a copy of such notice to each Member.

Section 16.8. Bank Accounts. The funds of the Company shall be deposited in the name of the Company in such bank accounts and with such signatories as shall be selected by the Board of Managers. All deposits, including security deposits, funds required to be escrowed and other funds not currently distributable or needed in the operation of the Company business shall, to the extent permitted by law, be deposited in such interest-bearing bank accounts or invested in such financial instruments (including, without limitation, hedge contracts and commodity contracts) as shall be approved by the Board of Managers.

XVII. DISSOLUTION, WINDING UP AND DISTRIBUTION

Section 17.1. Events of Dissolution. Each of the following shall be an “Event of Dissolution,” and unless the Company and its business is continued pursuant to Section 17.5 hereof, the Company shall be dissolved:

(a) upon the approval by Member Consent of an election to dissolve the Company;

(b) at any time there are no Members, unless the business of the Company is continued pursuant to Section 18-801(4) of the Act; or

The death, retirement, resignation, expulsion, bankruptcy or dissolution of any Member or the occurrence of any other event that terminates the continued membership of any Member shall not cause the Company to be dissolved or its affairs to be wound up.

Section 17.2. Dissolution and Winding Up. Notwithstanding any other provision of this Agreement, upon the dissolution of the Company, the Board of Managers (which term, for purposes of this Section and Section 17.4 shall include the respective trustee, receiver or successor, if any, of either or both thereof) shall have the responsibility for expeditiously dissolving and liquidating the Company. They shall promptly proceed to wind up the affairs of the Company and, after payment (or making provision for payment) of liabilities owing to creditors, shall set up such reserves as they deem reasonably necessary or appropriate for any contingent or unforeseen liabilities or obligations of the Company. Said reserves may be paid over to a bank or an attorney-at-law, to be held in escrow for the purpose of paying any such contingent or unforeseen liabilities or obligations. After paying such liabilities and setting up such reserves, the Board shall cause the remaining net assets of the Company to be paid or distributed to the Members or their assigns in accordance with the positive Capital Account balances of the Members. At the expiration of such period as the Board of Managers may deem advisable, any remaining reserves shall be paid or distributed to the Members or their assigns in the same manner as the preceding sentence. No Member shall receive any additional compensation for any services performed pursuant to this Article XVII.

Section 17.3. Final Statement. Upon the dissolution of the Company, a final certified statement of its assets and liabilities shall be prepared by the Company’s certified public accountants and furnished to the Members within ninety (90) days after such dissolution.

Section 17.4. Distribution In-Kind. If all the Members agree that it shall be impractical to liquidate part or all the assets of the Company, then assets which they agree are not suitable for liquidation may be distributed to the Members in-kind, subject to the order of priority set forth in Section 17.2 hereof and, further, subject to such conditions relating to the management and disposition of the assets distributed as the Board of Managers deems reasonable and equitable. If Company assets are to be distributed in-kind, then prior to any such distribution, the Capital Accounts of the Members shall be adjusted to reflect the manner in which the unrealized taxable income, gain, loss and deduction inherent in such property (to the extent that such items

have not been previously reflected in the Capital Accounts) would be allocated among the Members if there were a taxable disposition of such property on the date of its distribution for its then fair market value determined mutually by the Members.

Section 17.5. Deemed Distribution and Recontribution. Notwithstanding any other provision of this Article XVII, in the event the Company is liquidated within the meaning of Regulations Section 1.704-1(b)(2)(ii)(g) but no Event of Dissolution has occurred, the assets of the Company shall not be liquidated, the Company’s liabilities shall not be paid or discharged, and the Company’s affairs shall not be wound up. Instead, the Company shall be deemed to have contributed its assets in-kind to a new limited liability company, which shall be deemed to have assumed and taken all Company assets subject to all Company liabilities. Immediately thereafter, the Company shall be deemed to have liquidated and distributed the interests in the new limited liability company in-kind to the Members.
