ARTICLE 3

CAPITAL AND CAPITAL ACCOUNTS

3.1 CAPITAL STRUCTURE. The ownership interests in the Company shall be evidenced by Membership Interests, with each Membership Interest evidencing a specific percentage interest in the Company during its existence and in its assets upon its dissolution.

3.2 CAPITAL CONTRIBUTIONS. As of the next business day following the Relevant Interest Notice Date, Management LLC (or its predecessors) shall have made cumulative Capital Contributions to the Company equal to 10% of the Funded Capital (as defined in the LADA). Subsequent Capital Contributions shall be made as set forth below. If Management LLC has funded more than 10% of the Funded Capital as of such date, Management LLC shall be entitled to a return of such excess.

3.3 MEMBERS. Subject to Section 15.16, the Members of the Company are GeoResources and Management LLC. Each Member’s Membership Interest in the Company will be determined as follows:

(a) Management LLC’s Membership Interest shall be a percentage interest determined by dividing (i) ten percent (10%) by (ii) the difference between one hundred percent (100%) and CEU’s AMI Interest; and

(b) GeoResources’ Membership Interest shall be a percentage interest determined by dividing (i) the difference between ninety percent (90%) and CEU’s AMI Interest, by (ii) the difference between one hundred percent (100%) and CEU’s AMI Interest.

Subject to Section 6.8(b), Persons may be admitted to the Company as Members as determined by the Managers. The terms of admission or issuance may provide for the creation of different classes or groups of Members having different rights, powers and duties. The Managers may reflect the creation of any new class or group in an amendment to this Agreement indicating the different rights, powers and duties, and subject to such amendment being approved by the unanimous consent of the Members. Any such admission is effective only after such new Member has executed and delivered to the Members and the Company an instrument containing the notice address of the new Member, the Member’s ratification of this Agreement and agreement to be bound by it.

3.4 SUBSEQUENT CAPITAL CONTRIBUTIONS. No Member shall be required to make any Subsequent Capital Contribution to the Company, except as may be required under the provisions of this Section 3.4, or as required by applicable law. With respect to Subsequent Capital Contributions, the following provisions shall apply:

(a) LADA. The Members acknowledge that the Company is subject to the terms of the LADA. Terms used in this Section 3.4 that are defined in the LADA shall have the meanings given in the LADA.

(b) Further Subsequent Capital Contributions. GeoResources agrees to make Subsequent Capital Contributions to the Company in an amount sufficient to fund the reacquisition of CEU interests, the acquisition of additional leases, and fund certain drilling obligations either through Subsequent Capital Contributions or directly, both as specified below, equal to the “Required Funder Commitment” under the LADA, but not to exceed $60,000,000, without the express approval of Geo Resources, for the purposes set forth in this Section 3.4.

(c) Reacquisition of CEU Interests. Upon the execution of this Agreement, CEU will have the right to specify CEU’s AMI Interest under the LADA, and upon receipt of the Relevant Interest Notice from CEU by the Company (the date of such receipt being referred to herein as the “Relevant Interest Notice Date”) will be required to pay CEU the CEU Returned Capital. GeoResources shall contribute to the Company the funds necessary for the Company to pay the CEU Returned Capital to CEU within the time periods set forth in the LADA. The funding of these Subsequent Capital Contributions for lease acquisitions will occur in stages with the initial funding sufficient to make the acquisition from CEU for leases shown as “Closed” on Exhibit A and for leases that are shown as “Pending” or “Possible” and that are funded by CEU and Trigon on or before the Relevant Interest Notice Date.

(d) Acquisition of Additional Leases under the LADA. Each Member of the Company will make Subsequent Capital Contributions in proportion to their respective Membership Interests as from time to time required for the Company to fund its requisite portion of the costs for the acquisition of all subsequent leases under the LADA.

(e) Drilling Obligations. In addition to the foregoing capital contributions, GeoResources will drill or cause the drilling of (i) at least 10 gross ▇▇▇▇▇ (the “Carry ▇▇▇▇▇”) on the acreage held by Company (such that Management LLC is carried on 1 net well (subject to reduction as set forth below) to the tanks, with Management LLC being deemed to own for these purposes an interest in each Carry Well equal to Trigon’s working interest in each such well multiplied by Management LLC’s ownership interest in the Company), with one hundred percent (100%) of the drilling and completion costs (related to the Company’s interest in the Carry ▇▇▇▇▇) to be funded by GeoResources, and (ii) after the Carry ▇▇▇▇▇, 10 additional gross ▇▇▇▇▇ (“Subsequent ▇▇▇▇▇”). For all Subsequent ▇▇▇▇▇, the Company’s share of drilling and completion costs shall be funded by Subsequent Capital Contributions made by the Members in proportion to their Membership Interests, or at the direction of GeoResources may be funded directly to the operator of the drilling unit, if such operator is GeoResources or an affiliate of Management LLC. Further, to the extent that a third party is the operator and the Company is a non-operating participant, GeoResources will request the operator to recognize the interests of GeoResources and Management LLC directly for purpose of joint interest ▇▇▇▇▇▇▇▇ under the relevant joint operating account; provided, that in the event such non-operated well is a Carry Well, GeoResources will be responsible for all of the drilling and completion costs associated with such well. The Carry ▇▇▇▇▇ may be reduced by a percentage equal to one minus the Acreage Shortfall Percentage, as defined below, if the Acreage Shortfall Percentage is less than 100%. All ▇▇▇▇▇ drilled by the Company, whether in operated or non-operated drilling units, will be subject to the GeoResources’ approval (based on anticipated economic results satisfactory to GeoResources) and a failure to drill or participate shall not subject GeoResources to any penalties or damages under this Agreement or otherwise.

(f) As used herein, “Acreage Shortfall Percentage” shall mean that percentage determined by dividing the net mineral acres (on 8/8ths basis) for the Leases that are acquired by the Company by 14,000. The Members acknowledge that the leases shown as “Possible” on Exhibit A are not subject to an existing agreement between the landowner and the Company and in the event that the Company is not able to acquire any of the leases shown as “Possible” on Exhibit A, the Members will use their reasonable best efforts to agree on replacement acreage that is acceptable from a land (based on the bonus payment, landowner royalty, term and lease provision) and geologic perspective to be acquired in lieu of such “Possible” leases.

(g) To the extent that the Company has insufficient cash to fund its ongoing administrative expenses, including, without limitation, accounting expenses under Article 13 and tax report preparation under Article 11, each Member shall make a capital contribution in proportion to its Membership Interest in such amounts as from time to time requested by the Managers for such expenses.

(h) All Subsequent Capital Contributions required hereunder shall be paid to the Company within ten business days or, in the case of payments made pursuant to the LADA, within the time specified in the LADA, following written notice from the Managers specifying in reasonable detail the expenditures to which such capital contribution relates.

(i) In addition to the foregoing obligations of GeoResources, GeoResources shall pay to Management LLC a fee of $1,000,000 in consideration of general and administrative expenses incurred by Management LLC prior to the date hereof; provided, however, that such fee shall be reduced in the event the Acreage Shortfall Percentage is less than 100%, in which case the total fee due to Management LLC shall not exceed $1,000,000 times the Acreage Shortfall Percentage. The fee due to Management LLC shall be paid in increments proportional to the incremental payments by GeoResources for the leases as set forth on Exhibit A.

(j) Under no circumstances shall Management LLC be required to make any Subsequent Capital Contribution hereunder if GeoResources is not also making its prorata share of such Subsequent Capital Contribution due to the limitations set forth in Section 3.4(b).

3.5 FAILURE TO CONTRIBUTE.

(a) If a Member (the “Delinquent Member”) does not contribute by the time required all or any portion of an additional Capital Contribution that such Member is required to make under Sections 3.4 (the “Default Amount”), then the Company, at the direction of the other members (the “Non-Defaulting Members”) holding a majority of the Membership Interests of the Non-Defaulting Members, may take any or all of the following actions:

(i) pursue any remedies at law to collect the Default Amount and any interest accrued thereon, and recover the costs of collection; or

(ii) require the Non-Defaulting Members to make a Capital Contribution to the Company in an amount equal to the Default Amount, in the proportion that their Membership Interests bear to each other, which shall be treated as a recourse loan from the Non-Defaulting Members to the Delinquent Member, secured by the Delinquent Member’s Membership Interest (the “Default

Loan”), and as a Capital Contribution of that same amount to the Company by the Delinquent Member. The principal balance of the Default Loan shall be equal to the aggregate amount of the Capital Contribution made by the Non-Defaulting Members pursuant to this Section 3.5(a), and shall bear interest at a rate equal to the Default Interest Rate. The Non-Defaulting Members are hereby authorized to take all actions and sign all documents they deem required or necessary to perfect their security interest in the Delinquent Member’s Membership Interest. While any Default Loan is outstanding and unrepaid, the Company shall pay directly to the Non-Defaulting Members (in the same proportions that the Non-Defaulting Members made the Capital Contribution to the Company) any distributions to which the Delinquent Member is entitled pursuant to Article 4 until such Default Loan with interest has been repaid in full. The principal and accrued but unpaid interest under the Default Loan shall be due and payable in full on the third anniversary of the date on which the Default Loan was made. If any Default Loan and accrued but unpaid interest thereon is not paid when due, the Non-Defaulting Members shall, without forfeiting other remedies, be entitled to continue to receive all amounts that would otherwise be distributed by the Company to the Delinquent Member until such Default Loan with all accrued but unpaid interest (plus any costs of collection) is paid in full.

(b) THE MEMBERS AGREE THAT THE LIQUIDATED DAMAGES DESCRIBED IN THIS SECTION 3.5 ARE A FAIR AND ADEQUATE MEASURE OF THE DAMAGES THAT WILL BE SUFFERED BY THE NON-DEFAULTING MEMBERS AS A RESULT OF A BREACH BY A MEMBER OF ITS OBLIGATION TO MAKE CAPITAL CONTRIBUTIONS UNDER SECTIONS 3.4 AND NOT A PENALTY.

3.6 NO THIRD PARTY RIGHT TO ENFORCE. No Person other than a Member shall have the right to enforce any obligation of a Member to contribute capital hereunder and specifically no lender or other third party shall have any such rights.

3.7 LOANS TO THE COMPANY. Any Member, directly or through an Affiliate, may at any time or from time to time lend funds to the Company with the consent of the Managers. Any such loan shall be repayable by the Company to the Member (or its Affiliate, if applicable) at such date or dates as they may agree, and shall bear interest and carry such other terms as they may agree at a fair market interest rate and terms for similar loans between unaffiliated parties. The Members expressly agree and acknowledge that nothing in this Section 3.8 shall be deemed to require or otherwise obligate any Member to make any such loan to the Company. A loan by a Member to the Company shall not increase the interest of the lending Member in the capital of the Company and shall not entitle such Member to any increased share in the Company’s capital, Profits or Losses.

3.8 CAPITAL ACCOUNTS.

(a) A Capital Account shall be established for each Member and shall be determined and maintained in accordance with the provisions of Code Section 704 and the Regulations thereunder. A Member that has more than one class or series of Membership Interests shall have a single Capital Account that reflects all such class, classes or series of

Membership Interests and regardless of time or manner in which such Membership Interests were acquired. In addition to such other adjustments as may be required under this Agreement or pursuant to such Regulations, each Member’s Capital Account shall be (a) increased by (i) such Member’s Capital Contribution to the Company, plus (ii) the amount of any Profits and Liquidating Gains allocated to such Member and items of Capital Account Gross Income specially allocated to such Member pursuant to Article 5, and (b) decreased by (i) the amount of any Losses and Liquidating Losses allocated to such Member and items of Capital Account Deduction specially allocated to such Member pursuant to Article 5, (ii) the amount of any cash or other assets distributed to such Member by the Company, and (iii) the fair market value, as determined by the Managers, of any property distributed, or deemed hereunder to be distributed, to such Member by the Company (net of any liabilities that such Member is considered to assume or take subject to under Code Section 752 upon any such distribution of property).

(b) In accordance with Regulations Section 1.704-1(b)(2)(iv)(e), immediately prior to the actual or deemed distribution of any Company asset in kind, the Capital Accounts of all Members and the Company’s book carrying value of such Company asset shall be adjusted upward or downward to reflect any unrealized gain or unrealized loss attributable to such Company asset as if such unrealized gain or unrealized loss had been recognized upon an actual sale of such Company asset immediately prior to such distribution and had been allocated to the Members at such time pursuant to Article 5. For purposes of determining such unrealized gain or unrealized loss, the fair market value, as determined by the Managers, of Company assets shall be used.

(c) Upon any event described in Regulation Section 1.704-1(b)(2)(iv)(f)(5), the Capital Accounts may, at the Discretion of the Managers, be restated to reflect a revaluation of the assets of the Company in order to reflect the manner in which the unrealized income, gain, loss, or deduction inherent in such property (that has not been reflected in the Capital Accounts previously) would be allocated among the Members if there were a taxable sale of such assets for their fair market value as determined by the Managers.

(d) Upon any Transfer of Membership Interests, the Transferee shall be credited on the Company’s books with the portion of the Transferor’s Capital Account that corresponds to the Transferred Membership Interests.

3.9 GENERAL PROVISIONS REGARDING CAPITAL CONTRIBUTIONS. Except as otherwise expressly provided in this Agreement (a) no Member shall have the right to demand or receive a return of its Capital Contribution, (b) under circumstances requiring hereunder a return of any Capital Contribution, no Member shall have the right to demand or receive property other than cash, and (c) no Member shall receive any interest, salary or draw with respect to its Capital Contribution or its Capital Account. An unrepaid Capital Contribution is not a liability of the Company or of any Member. A Member shall not be required to contribute or to lend any cash or property to the Company to enable the Company to return any Member’s Capital Contribution.

3.10 LIMITATION ON LIABILITY. Except as otherwise required under the Act, the debts, obligations and liabilities of the Company, whether arising in contract, tort or otherwise, shall be solely the debts, obligations and liabilities of the Company, and no Member

shall be personally liable for or otherwise obligated with respect to any such debt, obligation or liability of the Company by reason of being a Member of the Company. The Members agree that the rights, duties and obligations of the Members in their capacities as members of the Company are only as set forth in this Agreement and as otherwise arise under the Act. Furthermore, the Members agree that the existence of any rights of a Member, or the exercise or forbearance from exercise of any such rights shall not create any duties or obligations of the Member in their capacities as members of the Company, nor shall such rights be construed to enlarge or otherwise alter in any manner the duties and obligations of the Members.

ARTICLE 4

DISTRIBUTION OF COMPANY FUNDS

4.1 DISTRIBUTIONS GENERALLY. Except as provided in Section 3.5, above, and Section 4.4, below, distributions to the Members shall be made only to all Members simultaneously on a pro rata basis in accordance with the percentage of Membership Interests held by each Member; provided, however, that any loans from Members pursuant to Section 3.7 hereof that are then due and payable shall be repaid prior to any distributions to Members.

4.2 OPERATING DISTRIBUTIONS. Distributions, other than distributions payable in accordance with Sections 4.3 hereof, shall be made at such times and in such amounts equal to all distributions of any nature received by the Company from the Partnership, except for such amounts determined by the Managers to be retained for the necessary expenses of the Company and for the reasonable and necessary reserves as determined from time to time by the Managers in its sole Discretion.

Distributions under this Section 4.3 shall be made equally to the Members in proportion to their Membership Interests.

4.4 DISTRIBUTIONS ON DISSOLUTION AND WINDING UP.

under the LADA (the “CEU Spud Fee”). The Members agree that the CEU Spud Fee shall be distributed (and allocated among the parties for tax purposes) as follows:

40% to GeoResources; and

(c) The Members agree to use reasonable good faith efforts to negotiate compensation for the Operator of the ▇▇▇▇▇ drilled under the LADA, in accordance with industry practices, in the event that an affiliate of Management LLC acts as Operator, or in the event that GeoResources or an affiliate of Management LLC is operating multiple drilling rigs on the lands covered by the LADA. In no case, shall an affiliate of Management LLC be required to serve as operator without being reasonably compensated for out-of-pocket expenses incurred in connection with operations and for other expenses mutually determined by the parties.

(d) If GeoResources or an affiliate of Management LLC serves as Operator and therefore bills and collects the CEU Spud Fee, it shall promptly upon receipt distribute such CEU Spud Fee, as specified above.

4.6 LIMITATION ON DISTRIBUTIONS. Notwithstanding any other provision to the contrary in this Agreement, the Company shall not make a distribution to any Member if such distribution would violate the Act or other applicable law.

4.7 WITHHOLDING OF TAXES. The Company will withhold taxes from distributions to the extent required to do so by applicable law.

The termination of any action, suit or proceeding by judgment, order, settlement, conviction or upon a plea of nolo contendere, or its equivalent, shall not create a presumption that the Covered Person acted in a manner contrary to that specified above. Any indemnification pursuant to this Section shall be made only out of the assets of the Company, it being agreed that the Members, Managers and officers shall not be personally liable for such indemnification and shall have no

obligation to contribute or loan any monies or property to the Company to enable it to effectuate such indemnification.

(b) To the fullest extent permitted by law, expenses (including legal fees and expenses) incurred by a Covered Person who is indemnified pursuant to Section 9.1(a) in defending any claim, demand, action, suit or proceeding shall, from time to time, be advanced by the Company prior to the final disposition of such claim, demand, action, suit or proceeding upon receipt by the Company of any undertaking by or on behalf of the Covered Person to repay such amount if it shall be determined that the Covered Person is not entitled to be indemnified as authorized in this Section 9.1.

(c) The indemnification provided by this Section 9.1 shall be in addition to any other rights to which a Covered Person may be entitled under any agreement, pursuant to any vote of the Members, as a matter of law or otherwise, both as to actions in the Covered Person’s capacity as a Covered Person and as to actions in any other capacity, and shall continue as to a Covered Person who has ceased to serve in such capacity and shall inure to the benefit of the heirs, successors, assigns and administrators of the Covered Person.

(d) The Company may purchase and maintain insurance, on behalf of the Managers, officers and Members and such other Persons as the Managers shall determine, against any liability that may be asserted against or expense that may be incurred by such Person in connection with the Company’s activities or such Person’s activities on behalf of the Company, regardless of whether the Company would have the power to indemnify such Person against such liability under the provisions of this Agreement.

(e) For purposes of this Section 9.1, the Company shall be deemed to have requested a Covered Person to serve as fiduciary of an employee benefit plan whenever the performance by it of its duties to the Company also imposes duties on, or otherwise involves services by, it to the plan or participants or beneficiaries of the plan; excise taxes assessed on a Covered Person with respect to an employee benefit plan pursuant to applicable law shall constitute “fines” within the meaning of Section 9.1(a); and action taken or omitted by it with respect to any employee benefit plan in the performance of its duties for a purpose reasonably believed by it to be in the interest of the participants and beneficiaries of the plan shall be deemed to be for a purpose which is in, or not opposed to, the best interests of the Company.

(f) In no event may a Covered Person subject the Members to personal liability by reason of the indemnification provisions set forth in this Agreement.

(g) A Covered Person shall not be denied indemnification in whole or in part under this Section 9.1 because the Covered Person had an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of this Agreement.

(h) The provisions of this Section 9.1 are for the benefit of the Covered Persons, their heirs, successors, assigns and administrators and shall not be deemed to create any rights for the benefit of any other Persons.

EXHIBIT B

ADDITIONAL ALLOCATIONS

The following Items are hereby incorporated into the Agreement:

1. Solely for purposes of determining a Member’s Capital Account in applying the provisions of Items 1 through 7 of this Exhibit B, the anticipated adjustments, allocations and distributions described in Regulations Section 1.704-l(b)(2)(ii)(d)(4)-(6) shall be taken into account, and each Member shall be deemed obligated to restore any deficit in its Capital Account to the extent of the sum of its share of the “Minimum Gain”, as determined pursuant to Regulations Section 1.704-2(g)(1), and its share of the “Partner Nonrecourse Debt Minimum Gain”, as determined pursuant to Regulations Section 1.704-2(i)(5).

2. Notwithstanding any other provision of this Exhibit B or of Section 3.4 or Article 5, no allocation of Loss or Liquidating Loss (or items thereof) shall be made to any Member if such allocation would result in such Member having a negative balance in its Capital Account at the close of such year in excess of the amount it would be required to restore, or is deemed to be obligated to restore on a liquidation of the Company at the close of such year. Any Loss or Liquidating Loss (or items thereof) that cannot be allocated to a Member pursuant to the restrictions contained in this Item 2 of Exhibit B shall be allocated to the other Members of the Company (to the extent not inconsistent with the restrictions of this Item 2 of Exhibit B) in accordance with the ratio of their then respective Capital Account balances.

3. Notwithstanding any other provision of this Exhibit B or of Section 3.4 or Article 5, in the event any Member unexpectedly receives an adjustment, allocation or distribution described in clause (4), (5) or (6) of Regulations Section 1.704-1(b)(2)(ii)(d) that results in such Member having a negative balance in its Capital Account at the close of such year in excess of the amount that it is obligated to restore or deemed obligated to restore on a liquidation of the Company at the close of such year, or for any other reason has a deficit Capital Account balance in excess of such amount, such Member shall be allocated Profit or Liquidating Gain (or items thereof), prior to the allocations pursuant to Sections 3.4, 5.1 or 5.2, in an amount and manner sufficient to eliminate such excess as promptly as possible.

4. In accordance with and pursuant to Regulations Section 1.704-2(i)(1), all “Partner Nonrecourse Deductions”, as defined in that Regulation, shall be allocated to the Member that bears the economic risk of loss on the “Partner Nonrecourse Debt”, as defined in Regulation Section 1.704-2(b)(4), giving rise to such deductions as determined under that Regulation.

5. In accordance with and pursuant to Regulation Sections 1.704-2(f) and 1.704-2(i)(4) (and subject to the exceptions set forth therein), if there is a net decrease in either Minimum Gain or Partner Nonrecourse Debt Minimum Gain or both during any taxable year, all Members shall be allocated, before any other allocation is made of Profit or Liquidating Gain (and other income and gain) and Loss or Liquidating Loss (or other loss or deduction) for such taxable year, items of Profit and Liquidating Gain for such year (and, if necessary, subsequent years) in an amount equal to the Member’s share in the decrease in Minimum Gain or Partner

Nonrecourse Debt Minimum Gain, as determined pursuant to Regulation Sections l.704-2(g)(2) and 1.704-2(i)(4).

6. To the extent an adjustment to the adjusted tax basis of any Company asset pursuant to Section 734(b) or 743(b) of the Code is required, pursuant to Regulation Sections 1.704-1(b)(2)(iv)(m)(2) or 1.704-1(b)(2)(iv)(m)(4), to be taken into account in determining Capital Accounts, the amount of such adjustment to Capital Accounts shall 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 Member or Members to whom such adjustment relates as determined in accordance with such Regulations.

7. It is the intent of the parties to this Agreement that allocation required by Items 1 through 5 of this Exhibit B (the “Regulatory Allocations”) satisfy the requirements of certain Regulations under Section 704(b) of the Code. It is further intended that the allocations under this Exhibit B and under Section 3.4 and Article 5 shall effect an allocation for Federal income tax purposes in a manner consistent with Section 704(b) of the Code and comply with any limitations or restrictions therein and, to the extent possible, that any allocations pursuant to Items 1 through 5 of Exhibit B shall be offset with other special allocations of Profits, Losses, Liquidating Gains and Liquidating Losses (or items thereof) in whatever manner the Managers reasonably and in good faith determine so that, after such offsetting allocations are made, each Member’s Capital Account balance is (to the extent possible) equal to the Capital Account balance such Member would have had if the Regulatory Allocations were not part of this Agreement and all items of income, gain, loss and deduction were allocated pursuant to Sections 3.4, 5.1 and 5.2. In exercising its Discretion under this Item 7 of Exhibit B, the Managers shall take into account future Regulatory Allocations that, although not yet made, are likely to offset other Regulatory Allocations previously made. If for any reason the allocations contained in this Agreement conflict with the Regulations promulgated under Section 704 of the Code, the Members acknowledge that such Regulations shall control.

8. For federal income tax purposes, except as otherwise provided in Items 8, 9 or 10 of this Exhibit B, items of income, gain, loss and deduction shall be allocated in accordance with the allocation of the corresponding item of Profits, Losses, Liquidating Gains and Liquidating Losses for purposes of maintaining Capital Accounts.

9. For tax purposes, recapture of tax deductions arising out of a disposition of property shall, to the extent consistent with the allocations for tax purposes of the gain or amount realized giving rise to such recapture, be allocated to the Members in the same proportions as the recaptured deduction was originally allocated.

10. For tax purposes, income, gain, loss, and deduction with respect to property reflected in the Capital Accounts at a book value other than its adjusted basis shall be shared among the Members so as to take account of the variation between the basis of the property to the Company and its fair market value at the time of the contribution. The preceding sentence shall be administered in any manner determined by the Managers that is consistent with Treasury Regulations under Code Sections 704(c) and 704(b).
