ARTICLE IV

ALLOCATIONS OF PROFIT AND LOSS AND DISTRIBUTIONS

4.1 General Allocations of Profits and Losses.

(a) General Allocations. After giving effect to the allocations set forth in Sections 4.3(a) and 4.3(b), Profits and Losses for any fiscal year or other period shall be allocated as follows:

(i) Profits. Profits shall be allocated as follows:

(A) first, in an aggregate amount equal to, and in proportion to, the excess of the aggregate Losses previously allocated pursuant to Section 4.1(b) over the Profits allocated pursuant to this Section 4.1(a)(i)(A), until such excess is reduced to zero;

(B) next, in an aggregate amount equal to, and in proportion to, the excess of the aggregate Losses previously allocated pursuant to Section 4.1(a)(ii) over the Profits allocated pursuant to this Section 4.1(a)(i)(B), until such excess is reduced to zero;

(D) Notwithstanding the provisions of Sections 4.1(a)(i)(A), 4.1(a)(i)(B), and 4.1(a)(i)(C), Profits arising from the sale of all or substantially all of the assets of the Partnership in contemplation of a dissolution of the Partnership pursuant to Article VIII, such Profits shall be allocated as follows:

(1) first, to the Partners (other than Xxxxxx X. Xxxxxxxxx, Xxxx X. Xxxxxxx and Xxxxxxx X. Xxxxx) in accordance with their respective Partnership Interests;

(2) second, following the distribution of cash pursuant to Section 8.3(c), to the Partners then having a negative Capital Account, pro-rata, until such Capital Accounts equal zero; and

(3) third, to the Partners in accordance with their respective Partnership Interests.

(ii) Losses. Subject to the limitation in Section 4.1(b), Losses shall be allocated to the Partners in proportion to their Partnership Interests.

(b) Limitation on Loss Allocations. The aggregate amount of Losses allocated pursuant to Section 4.1(a)(ii) and the next sentence of this Section 4.1(b) to any Limited Partner for any fiscal year shall not exceed the maximum amount of Losses that may be allocated to such Limited Partner without causing such Limited Partner to have an Adjusted Capital Account Deficit at the end of such fiscal year. All Losses in excess of the limitation in this Section 4.1(b) with respect to any Limited Partner with a positive Adjusted Capital Account shall be allocated solely to the other Limited Partners in proportion to their Partnership Interests. If no other Limited Partner may receive an additional allocation of Losses pursuant to this Section 4.1(b), such additional Losses not allocated pursuant to Section 4.1(a) or the preceding sentence shall be allocated solely to those Partners that bear the economic risk for such additional Losses within the meaning of Section 704(b) of the Code and the Regulations thereunder. If it is necessary to allocate Losses under the preceding sentence, the General Partner shall determine those Partners that bear the economic risk for such additional Losses.

4.2 Distributions.

(a) General. All distributions of distributable cash and property shall be made at such time as determined by the General Partner (provided, that no distribution shall be declared and paid unless, after the distribution is made, the assets of the Partnership are in excess of all liabilities of the Partnership, except liabilities to Partners regarding their contributions),

who shall review the appropriateness of a distribution at least annually. All amounts withheld pursuant to the Code or any provisions of state or local tax law with respect to any payment or distribution to the Partners from the Partnership shall be treated as amounts distributed to the relevant Partner or Partners pursuant to this Section 4.2. All distributions shall be made at least annually to the Partners as follows:

(i) first, an aggregate amount of $20,000 per month to those Partners that have an outstanding Preference Contribution until the total amount of all Preference Contributions is reduced to zero;

(ii) second, on a quarterly basis, to each Partner that has an outstanding Preference Contribution, an amount that is sufficient, in the Managing Member’s sole discretion, to cover interest on the loan obtained by each Partner with an outstanding Preference Contribution to secure funding for such Preference Contribution;

(iii) third, during each month in which a payment is required pursuant to subsection (i) or (ii) above, following the monthly or quarterly payments as required above, to the Partners in proportion to their Partnership Interests; and

(iv) following reduction of the Preference Contributions to zero, to the Partners in proportion to their Partnership Interests.

(b) Minimum Distributions. Notwithstanding the provisions of Section 4.2(a) above, the General Partner shall make aggregate distributions of cash each fiscal year equal to the product of the net taxable income of the Partnership that is taken into account by its Partners for such fiscal year and, between 30% and the maximum marginal combined federal and state income tax rates for such fiscal year applicable to individuals who are residents of the State of Texas, with the actual tax rate that is used within such range to be determined by the General Partner in its sole discretion. Any such distribution of cash shall be made to the Partners in proportion to their Partnership Interests.

(c) Overriding Distribution. Notwithstanding the provisions of Section 4.2(a) above, if at any time distributions to a Partner would create or increase an Adjusted Capital Account Deficit and if another Partner has a positive Capital Account balance (after such Adjusted Capital Account Deficit and Capital Account balances have been adjusted to reflect the allocation of Profits and Losses pursuant to this Article III, taking into account interim Profits and Losses (determined using such accounting methods as shall be selected by the General Partner) for the period ending on or before such distribution), such cash flow shall be distributed first to the Partner having a positive Capital Account balance in an amount equal to such positive balance, and the remaining cash, if any, shall be distributed in accordance with Section 4.2(a).

(d) Payments Not Deemed Distributions. Any amounts paid pursuant to Article V, Section 6.1(e), or 6.1(i) shall not be deemed to be distributions for purposes of this Agreement.

(e) Withheld Amounts. Notwithstanding any other provision of this Section 4.2 to the contrary, each Partner hereby authorizes the Partnership to withhold and to pay over, or otherwise pay, any withholding or other taxes payable by the Partnership with respect to

the Partner as a result of the Partner’s participation in the Partnership; if and to the extent that the Partnership shall be required to withhold or pay any such taxes, such Partner shall be deemed for all purposes of this Agreement to have received a payment from the Partnership as of the time such withholding or tax is paid, which payment shall be deemed to be a distribution with respect to such Partner’s Partnership Interest to the extent that the Partner (or any successor to such Partner’s Partnership Interest) is then entitled to receive a distribution. To the extent that the aggregate amount of such payments to a Partner for any period exceeds the distributions to which such Partner is entitled for such period, the amount of such excess shall be considered a loan from the Partnership to such Partner. Such loan shall bear interest (which interest shall be treated as an item of income to the Partnership) at the lesser of the maximum rate permitted by law and the rate of interest per annum most recently established by Frost Bank and Trust, N.A. as such bank’s general reference rate of interest (which rate may or may not be the lowest rate of interest then charged by such bank), as determined hereunder from time to time, until discharged by such Partner by repayment, which may be made in the sole discretion of the General Partner out of distributions to which such Partner would otherwise be subsequently entitled. Any withholdings authorized by this Section 4.2(d) shall be made at the maximum applicable statutory rate under the applicable tax law unless the General Partner shall have received an opinion of counsel or other evidence satisfactory to the General Partner to the effect that a lower rate is applicable, or that no withholding is applicable.

(f) Distributions in Liquidation of Partner’s Partnership Interest. For purposes of this Agreement, a liquidation of a Partner’s Partnership Interest means the termination of the Partner’s entire Partnership Interest other than in connection with the dissolution, winding up, and termination of the Partnership. Where a Partner’s Partnership Interest is to be liquidated by a series of distributions, the Partnership Interest shall not be considered as liquidated until the final distribution has been made. If a Partner’s Partnership Interest is to be liquidated, liquidating distributions shall be made in accordance with the positive Capital Account balance of that Partner (as determined after taking into account all Capital Account adjustments with respect to that Partner’s Partnership Interest for the taxable year during which the liquidation occurs, as determined by the General Partner in accordance with Section 706 of the Code). A distribution in liquidation of a Partner’s Partnership Interest shall be made by the end of the taxable year in which such liquidation occurs, or, if later, within 90 days after the Partner’s Partnership Interest is liquidated.

4.3 Special Allocations of Profits and Losses.

(a) Special Allocations.

(i) Minimum Gain Chargeback-Partnership Nonrecourse Liabilities. If there is a net decrease in Partnership Minimum Gain during any Partnership taxable year, certain items of income and gain shall be allocated (on a gross basis) to the Partners in the amounts and manner described in Section 1.704-2(f) of the Regulations. This Section 4.3(a)(i) is intended to comply with the minimum gain chargeback requirement (set forth in Section 1.704-2(f) of the Regulations) relating to Partnership nonrecourse liabilities (as defined in Section 1.704-2(b)(3) of the Regulations) and shall be so interpreted.

(ii) Minimum Gain Chargeback—Partner Nonrecourse Debt. If there is a net decrease in Partner Minimum Gain during any Partnership taxable year, certain items of income and gain shall be allocated (on a gross basis) as quickly as possible to those Partners who had a share of the Partner Minimum Gain (determined pursuant to Section 1.704-2(i)(5) of the Regulations) in the amounts and manner described in Section 1.704-2(i)(4) of the Regulations. This Section 4.3(a)(ii) is intended to comply with the minimum gain chargeback requirement (set forth in Section 1.704-2(i)(4) of the Regulations) relating to partner nonrecourse debt (as defined in Section 1.704-2(b)(4) of the Regulations) and shall be so interpreted.

(iii) Qualified Income Offset. If any Partner has an Adjusted Capital Account Deficit, items of Partnership income and gain shall be specially allocated (on a gross basis) to each such Partner in an amount and manner sufficient to eliminate the Adjusted Capital Account Deficit of such Partner as quickly as possible; provided, however, that an allocation pursuant to this Section 4.3(a)(iii) shall be made only if and to the extent that a Partner would have an Adjusted Capital Account Deficit after all other allocations provided for in this Article III have been tentatively made as if this Section 4.3(a)(iii) were not in this Agreement. It is intended that this Section 4.3(a)(iii) constitute a “qualified income offset” within the meaning of Section 1.704-1(b)(2)(ii)(d) of the Regulations and shall be interpreted and applied in a manner consistent with such Regulations.

(iv) Gross Income Allocation. If any Partner has a deficit Capital Account at the end of any fiscal year, and such deficit Capital Account is in excess of the sum of (A) the amount such Partner is obligated to restore pursuant to any provisions of this Agreement and (B) the amount such Partner is deemed to be obligated to restore pursuant to the penultimate sentences of Regulations Section 1.704-2(g)(1) and 1.704-2(i)(S), each such Partner shall be specially allocated items of Partnership income and gain in the amount of such excess as quickly as possible, provided that an allocation pursuant to this Section 4.3(a)(iv) shall be made only if and to the extent that such Partner would have a deficit Capital Account in excess of such sum after all other allocations provided for in Sections 4.1 and 4.3 have been made as if Section 4.3(a)(iii) and this Section 4.3(a)(iv) were not in the Agreement.

(v) Basis Adjustments. To the extent an adjustment to the adjusted tax basis of any Partnership asset pursuant to Section 734(b) or 743(b) of the Code is required, pursuant to Section 1.704-1(b)(2)(iv)(m) of the Regulations, to be taken into account in determining Capital Accounts, the amount of such adjustment to the 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 Partners in a manner consistent with the manner in which their Capital Accounts are required to be adjusted pursuant to such Section of the Regulations.

(vi) Nonrecourse Deductions. Partner Nonrecourse Deductions shall be allocated in accordance with Section 1.704-2(i)(1) of the Regulations to the Partner who bears the economic risk of loss with respect to such deductions.

(vii) Allocation of Proceeds of Nonrecourse Liability. The determination of whether any distribution by the Partnership is allocable to the proceeds of a

nonrecourse liability of the Partnership shall be made by the General Partner under any reasonable method that is in compliance with Section 1.704-2(h) of the Regulations.

(viii) Allocation of Start-Up Costs. Start-Up Costs for any fiscal year or other period shall be specially allocated among those Limited Partners admitted to the Partnership on or before the last day of the first full tax year of the Partnership in proportion to their Capital Contributions, provided, however, if any such Limited Partners are admitted to the Partnership on different dates, all Start-Up Costs shall be divided among such Limited Partners, to the extent possible, so that the cumulative Start-Up Costs allocated to such Limited Partners at any time are always in proportion to their Capital Contributions. In the event the General Partner shall determine that such result is not likely to be achieved through the future allocations of Start-Up Costs, the General Partner may allocate a portion of Profits or Losses so as to achieve the same effect on the Capital Accounts of such Limited Partners, notwithstanding any other provision of this Agreement to the contrary.

(b) Curative Allocations. The allocations set forth in Sections 4.1(b) and 4.3(a) (the “Regulatory Allocations”) are intended to comply with certain requirements of Section 1.704-1(b) of the Regulations. The Partners hereby acknowledge and agree that the Regulatory Allocations may not be consistent with the manner in which the Partners intend to make Partnership distributions. Accordingly, the General Partner is hereby authorized and directed to make other allocations of Profit, Loss, or Book Depreciation among the Partners in any reasonable manner that the General Partner deems appropriate, in its sole discretion, so as to prevent the Regulatory Allocations from distorting the manner in which the Partnership distributions would otherwise be divided among the Partners pursuant to Sections 4.2, 8.3 and 8.4. In general, the Partners anticipate that this will be accomplished by specially allocating other Profits, Losses, or Book Depreciation among the Partners so that, after such offsetting special allocations are made, the amount of each Partner’s Capital Account will be, to the extent possible, equal to the Capital Account balance such Partner would have had if the Regulatory Allocations were not a part of this Agreement and all Partnership items had been allocated to the Partners solely pursuant to Section 4.1(a).

(c) Tax Allocations: Code Section 704(c). In accordance with Section 704(c) of the Code and the Regulations thereunder, income, gain, loss, and deduction with respect to any property contributed to the capital of the Partnership shall, solely for tax purposes, be allocated among the Partners so as to take account of any variation between the adjusted basis of such property to the Partnership for federal income tax purposes and the initial Gross Asset Value of such property (determined in accordance with Section 3.2(a)(iii)(A)). In accordance with the requirements of Section 1.704-1(b)(4)(i) of the Regulations, if the Gross Asset Value of any Partnership asset is adjusted pursuant to Section 3.2(a)(iii)(B). subsequent allocations of income, gain, loss, and deduction with respect to such asset shall take account of any variation between the adjusted basis of such asset for federal income tax purposes and the Gross Asset Value of such asset in the same manner as such variations are taken into account under Section 704(c) of the Code and the Regulations thereunder with respect to property contributed to the Partnership. Any elections or other decisions relating to such allocation shall be made by the General Partner in any manner that reasonably reflects the purpose and intention of this Agreement. Allocations pursuant to this Section 4.3(c) are solely for purposes of federal, state,

and local taxes and shall not affect or be taken into account in computing any Partner’s Capital Account or share of Profits, Losses, other items, or distributions pursuant to this Agreement.

(d) Other Allocation Rules.

(i) For purposes of determining the Profits, Losses, or any other item allocable to any period (including periods before and after the admission of a new Partner), Profits, Losses, and any such other item shall be determined on a daily, monthly, or other basis, as determined and allocated by the General Partner using any permissible method under Section 706 of the Code and the Regulations thereunder.

(ii) For federal income tax purposes, every item of income, gain, loss, and deduction shall be allocated among the Partners in accordance with the allocations under Sections 4.1, 4.3(a), 4.3(b), and 4.3(c).

(iii) The Partners are aware of the income tax consequences of the allocations made by this Section 4.3 and Section 4.1 and hereby agree to be bound by the provisions of this Section 4.3 and Section 4.1 in reporting their shares of Partnership income and loss for income tax purposes.

(iv) To the extent permissible under Section 704 of the Code and the Regulations thereunder, in making allocations provided for in this Section 4.3 and Section 4.1, ordinary income realized by the Partnership from recapture of previously reported deductions shall be allocated to those Partners (or their successors in interest) to whom such deductions were originally allocated and in proportion to such original allocations. Any obligation relating to the recapture of previously reported credits shall be allocated to those Partners (or their successors in interest) to whom such credits were originally allocated and in proportion to such original allocations.

(v) It is intended that the allocations in Sections 4.1, 4.3(a), 4.3(b), and 4.3(c) effect an allocation for federal income tax purposes consistent with Section 704 of the Code and comply with any limitations or restrictions therein. The General Partner shall have complete discretion to make the allocations pursuant to this Section 4.3 and Section 4.1 in any reasonable manner consistent with Section 704 of the Code and to amend the provisions of this Agreement as appropriate to comply with the Regulations promulgated under Section 704 of the Code, if in the opinion of counsel to the Partnership, such an amendment is advisable to reflect allocations among the Partners consistent with those Regulations.

(vi) The Partners agree that their Partnership Interests represent their interests in Partnership profits for purposes of allocating excess nonrecourse liabilities pursuant to Section 1.752-3(a)(3) of the Regulations.

The General Partner shall determine the expenses that are allocable to the Partnership in a manner that is fair and reasonable. Such reimbursements shall be in addition to any reimbursement to the General Partner as a result of the indemnification provided under Section 6.1(i). At the discretion of the General Partner, Partnership expenses may be billed directly to and paid by the Partnership.

to this Agreement or upon termination of the Partnership may be considered as such by law and then only to the extent provided for in this Agreement.

ARTICLE VII

TRANSFER, ASSIGNMENT AND SUBSTITUTION

7.1 Transfer of Interests.

(a) Transfer. No Partnership Interest shall be transferred, in whole or in part, except in accordance with the terms and conditions set forth in this Section 7.1. Any transfer or purported transfer of any Partnership Interest not made in accordance with this Section 7.1 shall be null and void. A purported transferee shall have no right to require any information or account of the Partnership’s transactions or to inspect the Partnership’s books. The Partnership shall be entitled to treat the purported transferor of a Partnership Interest as the absolute owner thereof in all respects, and shall incur no liability to any purported transferee for distributions to the Partner owning such Partnership Interest of record or for allocations of Profits, Losses, deductions, or credits or for transmittal of reports and notices required to be given to holders of Partnership Interests. The term “transfer,” when used in this Section 7.1 and in Section 7.3 with respect to a Partnership Interest, includes a sale, assignment, gift, pledge, encumbrance, hypothecation, mortgage, exchange, or any other disposition.

(b) Transfers by General Partner. With prior written approval of a Majority Interest, the General Partner may transfer all, but not less than all, of its Partnership Interest to any Person. Any transfer by the General Partner of its Partnership Interest under this Section 7.1(b) to an Affiliate of the General Partner or any other Person shall not constitute a withdrawal of the General Partner under Section 7.2(a), Section 8.1(b), or any other provision of this Agreement. If any such transfer is deemed to constitute a withdrawal under such provisions or otherwise and results in the dissolution of the Partnership under this Agreement or the laws of any jurisdiction to which the Partnership or this Agreement is subject, the Partners hereby unanimously consent to the reconstitution and continuation of the Partnership immediately following such dissolution, pursuant to Section 8.2.

(c) Right of First Refusal.

(i) Any Limited Partner who desires to transfer all or any portion of his Partnership Interest in the Partnership (a “Selling Owner’’) to a bona fide third party purchaser who is not then a Limited Partner or General Partner shall obtain from such proposed third party purchaser a bona fide written offer to purchase such Partnership Interest, stating the terms and conditions upon which the purchase is to be made and the consideration to be paid therefore. The Selling Owner shall give written notification to the remaining Partners, by certified mail or personal delivery, of his intention to so transfer such Partnership Interest, furnishing to the remaining Partners a copy of the aforesaid written offer to purchase such Partnership Interest.

(ii) The remaining Partners, and each of them, shall, on a basis pro rata to their Partnership Interests or on a basis pro rata to the Partnership Interests of those remaining Partners exercising their right of first refusal, have the right to exercise a right of first refusal to

purchase all (but not less than all) of the Partnership Interest proposed to be sold by the Selling Owner upon the same terms and conditions as stated in the aforesaid written offer to purchase by giving written notification to the Selling Owner, by certified mail or personal delivery, of their intention to do so within ten (10) days after receiving written notice from the Selling Owner. The failure of all of the remaining Partners (or any one or more of them) to so notify the Selling owner of their desire to exercise this right of first refusal within said ten (10) day period shall result in the termination of the right of first refusal and the Selling Owner shall be entitled to consummate the sale of the Partnership Interest that was subject to the written offer to such third party purchaser.

In the event the remaining Partners (or any one or more of the remaining Partners) give written notice to the Selling Owner of their desire to exercise this right of first refusal and to purchase all of the Selling Owner’s Partnership Interest that is the subject of the written offer upon the same terms and conditions as are stated in the written offer to purchase, the remaining Partners shall have the right to designate the time, date and place of closing, provided that the date of closing shall be within thirty (30) days after receipt of written notification from the Selling Owner of the third party offer to purchase.

(iii) In the event of the purchase of the Selling Owner’s Partnership Interest by a third party purchaser, and as a condition to recognizing one or more of the effectiveness and binding nature of any such sale and (subject to Section 7.1(e)) substitution of a new Partner as against the Partnership or otherwise, the remaining Partners may require the Selling Owner and the proposed purchaser, or successor-in-interest, as the case may be to execute, acknowledge and deliver to the remaining Partners such instruments of transfer, assignment and assumption and such other certificates, representations and documents, and to perform al such other acts which the remaining Partners may deem necessary or desirable to:

(A) constitute such purchaser, as a Partner or successor-in-interest as such;

(B) confirm that the Person desiring to acquire the Partnership Interest, or to be admitted as a Partner, has accepted, assumed and agreed to be subject and bound by all of the terms, obligations and conditions of this Agreement, as amended;

(C) preserve the Partnership after the completion of such sale, transfer, assignment or substitution under the laws of each jurisdiction in which the Partnership is qualified, organized or does business;

(D) maintain the status of the Partnership as a partnership for federal tax purposes; and

(E) assure compliance with any applicable state and federal laws, including securities laws and regulations.

(iv) Any sale of an Partnership Interest or admission of a Partner in compliance with this Section 7.1(c) shall be deemed effective as of the last day of the calendar month in which the remaining Partners’ consent thereto was given. The transferring Partner

agrees, upon request of the remaining Partners, to execute such certificates or other documents and perform such other acts as may be reasonably requested by the remaining Partners from time to time in connection with such sale, transfer, assignment, or substitution. The Selling Partner hereby indemnifies the Partnership and the remaining Partners against any and all loss, damage, or expense (including, without limitation, tax liabilities or loss of tax benefits) arising directly or indirectly as a result of any transfer of purported transfer in violation of this Section 7.1(c).

(v) Right to Participate in Sale.

(A) Participation Offer. Any written notification from a Selling Partner, who desires to sell all or any portion of his Partnership Interest to a non-affiliated third party purchaser, delivered pursuant to Section 7.1(c)(i), shall also contain an offer (the “Participation Offer’’) to each remaining Partner (each, a “Non-Selling Partner”) of the right, but not the obligation, to sell to the nonaffiliated third party purchaser pursuant to any bona fide offer (the ‘‘Third Party Offer”) a pro rata portion of the Partnership Interest to be sold pursuant to the Third Party Offer, for the same consideration (pro rata in accordance with their Partnership Interests) to be received by the Selling Partner.

(B) Acceptance of Participation Offer. If the Right of First Refusal is not exercised, each Non-Selling Partner shall accept or reject the Participation Offer in writing within 15 days after delivery of the Participation Offer. If accepted, and if the Non-Selling Partner desires to sell less than its pro rata portion, the notice of acceptance shall specify the maximum amount he agrees to sell. If any Non-Selling Partner fails to accept the Participation Offer within such 15-day period, or upon the earlier rejection in writing of the Participation Offer by any Non-Selling Partner, the Selling Partner shall be released from the obligations under this Section 7.1(c)(v) as to that Non-Selling Partner.

(C) Transfer Pursuant to Participation Offer. Each Non-Selling Partner agrees to execute and deliver such instruments of conveyance and transfer and to take such other action as may reasonably be required in connection with any transfer made pursuant to this Section 7.1(c)(v).

(vi) Notwithstanding anything in this Agreement to the contrary, the restrictions on transfers set forth in this Section 7.1(c) do not apply to transfer of Partnership Interests to the Partnership or to a then existing Partner.

(d) Transferee Not Partner in Absence of Consent. Notwithstanding anything contained herein to the contrary (including, without limitation, Section 7.1(c) hereof), if a Majority Interest does not approve by written consent the proposed sale of the Selling Partner’s Partnership Interest to a transferee who is not a Partner immediately prior to the sale, then the proposed transferee shall have no right to participate in the management of the business and affairs of the Partnership or to become a Partner. No transfer of a Partner’s interest in the Partnership shall be effective unless and until written notice (including the name and address of

the proposed transferee and the date of such transfer) has been provided to the Partnership and the non-transferring Partners.

(e) Additional Limitations. The General Partner may require, as a condition to any transfer of a Partnership Interest of a Limited Partner, that, in the General Partner’s reasonable determination, (i) the transfer will not jeopardize the treatment of the Partnership as a partnership for federal income tax purposes, and (ii) the transfer will not violate the registration requirements of applicable securities laws or cause any prior offer and sale of Partnership Interests to violate such requirements. The General Partner may also require the proposed transferee to deliver to the Partnership acceptable representations and warranties respecting its status under applicable securities laws and its investment intent with respect to the Partnership Interest, and may require the transferor and transferee to supply such other documentation as the General Partner may deem advisable in its sole discretion.

(f) Distributions and Allocations in Respect of Transferred Partnership Interests. If any Partnership Interest is transferred during any fiscal year in compliance with the provisions of this Article VII, Profits, Losses, and all other items attributable to the transferred interest for such period shall be allocated between the transferor and the transferee by taking into account their varying interests during the period in accordance with Section 706 of the Code, using any conventions permitted by law and selected by the General Partner. All distributions on or before the date of the transfer shall be made to the transferor. Solely for purposes of making such allocations and distributions, the Partnership shall recognize the transfer not later than the end of the calendar month during which it is given notice of the transfer; provided, however, that if the Partnership does not receive a notice stating the date the Partnership Interest was transferred and such other information as the General Partner may reasonably require within 30 days after the end of the fiscal year during which the transfer occurs, then all of such items shall be allocated, and all distributions shall be made, to the Person who, according to the books and records of the Partnership, on the last day of the fiscal year during which the transfer occurs, was the owner of the Partnership Interest. Neither the Partnership nor any Partner shall incur any liability for making allocations and distributions in accordance with the provisions of this Section 7.1(e), whether or not any Partner or the Partnership has knowledge of any transfer of ownership of any Partnership Interest.

7.2 Withdrawal or Removal of General Partner.

(a) Withdrawal. The General Partner shall have the right to withdraw from the Partnership at any time without penalty, upon 15 days’ written notice to Limited Partners. In the event of such withdrawal and the resulting dissolution of the Partnership, Limited Partners shall have the right to reconstitute and continue the Partnership in accordance with Section 8.2.

(b) Removal. At a meeting called expressly for that purpose, the General Partner may be removed from its position as General Partner at any time, with or without cause by the affirmative vote of Limited Partners holding at least 80% of the Voting Percentages of all Limited Partners. Following such a removal, a new general partner shall be selected by a Majority Interest.

(c) Interest of Withdrawing or Removed General Partner. If the General Partner shall withdraw or be removed in accordance with Section 7.2(a) or 7.2(b), the withdrawing General Partner shall become a Limited Partner and its Partnership Interest as a General Partner shall be converted into the Partnership Interest of a Limited Partner. Any successor General Partner shall, at the effective date of its admission to the Partnership, contribute to the capital of the Partnership cash or property or other consideration in an amount or having a fair market value, and in exchange for a Partnership Interest and Voting Percentage, as shall be acceptable to a Majority Interest This Agreement shall be amended to reflect any event described in this Section 7.2, and any successor General Partner covenants to so amend this Agreement.

7.3 Admission of Limited Partners and Successor General Partner.

(a) Admission of Limited Partners.

Limited Partners shall execute a counterpart of this Agreement and thereby agree to be bound by the terms of this Agreement. From the Commencement Date forward, any Person (who is not then an existing Partner) may only acquire a Partnership Interest in the Partnership upon receiving the affirmative vote of not less than 80% of the Voting Percentages of all Partners, whether any such Partnership Interest is acquired through or from the Partnership, through or from some type of Partnership benefit plan or as a transferee of a current Partner’s Partnership Interest or any portion thereof, subject to the other terms and conditions of this Agreement. To the extent such admission is approved, the General Partner shall be permitted to revise Exhibit A hereto to reflect the new Partnership Interests and Voting Percentages of all Partners. No new Limited Partners shall be entitled to any retroactive allocation or losses, income or expense deductions incurred by the Partnership. The General Partner may, at its option, at the time a new Limited Partner is admitted, close the Partnership books (as though the Partnership’s tax year had ended) or make pro rata allocations of loss, income and expense deductions to a new Limited Partner for that portion of the Partnership’s tax year in which a Limited Partner was admitted in accordance with the provisions of Section 706(d) of the Code and the Treasury Regulations promulgated thereunder. Any Person, following the approval procedure described above, who acquires a Partnership Interest as a Limited Partner directly from the Partnership shall be admitted to the Partnership as a Limited Partner upon the Partnership’s receipt of his Capital Contribution, and to the extent necessary, Exhibit A shall be amended to reflect the revised Partnership Interest and Voting Percentages of each Partner. Each such Limited Partner shall execute a counterpart of this Agreement and thereby agree to be bound by the terms of this Agreement.

(b) Admission of Substitute Limited Partners. A transferee (which may be the heir or legatee of a Limited Partner) or assignee of a Limited Partner’s Partnership Interest, or Person acquiring a Partnership Interest pursuant to any foreclosure made upon any permitted pledge or hypothecation of the Partnership Interest, shall be entitled to receive the distributive share of the Partnership’s Profits, Losses, deductions, and credits attributable to such Partnership Interest, provided that such transfer shall have been subjected to the right of first refusal rights provided in Section 7.1(c). No transferee, assignee, heir, or legatee shall become a substitute Limited Partner without the prior written consent of the General Partner, which consent will be

given only in the sole discretion of the General Partner. Upon written consent by the General Partner, the transferee, assignee, heir, or legatee shall execute a counterpart of this Agreement, thereby agreeing to be bound by the terms of this Agreement with respect to the Partnership Interest so transferred. Upon admission of a substitute Limited Partner, the substitute Limited Partner shall be subject to all of the restrictions applicable to, shall assume all of the obligations of, and shall attain the status of a Limited Partner under and pursuant to this Agreement with respect to the Partnership Interest held by the substitute Limited Partner.

(c) Admission of Successor General Partner. A successor General Partner selected pursuant to Section 8.2 or the transferee of or successor to all of the Partnership Interest of the General Partner pursuant to Section 7.1(b) or a replacement General Partner elected by a Majority Interest following the removal of a General Partner pursuant to Section 7.2(b) shall be admitted to the Partnership as the General Partner, effective as of the date of the withdrawal or removal of the predecessor General Partner or the date of transfer of the predecessor’s Partnership Interest.

(d) Action by General Partner. In connection with the admission of any substitute Limited Partner or successor General Partner, the General Partner shall have the authority to take all such actions as it deems necessary or advisable in connection therewith, including the amendment of Exhibit A to this Agreement and the execution and filing with appropriate authorities of any necessary documentation.

7.4 Major Decisions. The following actions by the Partnership require the approval of a Majority Interest:

Upon the occurrence of an event described in Section 8.1(b) or 8.1(d), the Partnership shall be deemed to be dissolved and reconstituted if, (a) there remains at least one general partner, in which case the business of the Partnership may be carried on by the remaining general partner (or general partners), or (b) within 90 days after such event, all of the remaining Partners (i) elect in writing to continue the business of the Partnership and, (ii) to the extent that they desire or if there are no remaining general partners, agree to the appointment, effective as of the date of withdrawal of the General Partner, of one or more new general partners.

If an election to continue the Partnership is made upon the occurrence of an event described in Section 8.1(b) or 8.1(d), then:

(a) the Partnership shall be deemed to be reconstituted and shall continue until the end of the term for which it is formed unless earlier dissolved in accordance with this Article VIII;

Upon dissolution, removal, or resignation of the Liquidator, a successor and substitute Liquidator (who shall have and succeed to all rights, powers, and duties of the original Liquidator) shall within 30 days thereafter be selected by a Majority Interest. The right to appoint a successor or substitute Liquidator in the manner provided herein shall be recurring and continuing for so long as the functions and services of the Liquidator are authorized to continue under the provisions of this Agreement, and every reference herein to the Liquidator will be deemed to refer also to any successor or substitute Liquidator appointed in the manner herein provided.

The Liquidator shall liquidate the assets of the Partnership and apply and distribute the proceeds of liquidation in the following order of priority, unless otherwise required by mandatory provisions of applicable law:

Xxxxx) or their lawful assignees, in accordance with the positive balances in their Capital Accounts as provided in Section 1.704-1(b)(2)(ii)(b)(2) of the Regulations (such computation to be made after the final allocation of gain is made among the Capital Accounts of all Partners);

8.4 Distribution in Kind. Notwithstanding the provisions of Section 8.3 which require the liquidation of the assets of the Partnership, but subject to the order of priorities set forth therein, if on dissolution of the Partnership the Liquidator determines that an immediate sale of part or all of the Partnership’s assets would be impractical or would cause undue loss to the Partners, the Liquidator may defer for a reasonable time the liquidation of any assets except those necessary to satisfy liabilities of the Partnership (other than those to Partners) and may distribute to the Partners, in lieu of cash, as tenants in common and in accordance with the provisions of Section 8.3, undivided interests in Partnership assets that the Liquidator deems not suitable for liquidation. Any such distributions in kind shall be subject to conditions relating to the disposition and management of such properties that the Liquidator deems reasonable and equitable and to any joint operating agreements or other agreements governing the operation of the properties at the time. The Liquidator shall determine the fair market value of any property distributed in kind using any reasonable method of valuation it may adopt.

8.5 Cancellation of Certificate of Limited Partnership. Upon the completion of the distribution of Partnership property as provided in Sections 8.3 and 8.4, the Partnership shall be terminated, and the Liquidator (or the General Partner and Limited Partners if required by law) shall cause the cancellation of the Certificate of Limited Partnership in the State of Texas and of all qualifications and registrations of the Partnership as a foreign limited partnership in jurisdictions other than the State of Texas and shall take such other actions as may be necessary to terminate the Partnership.

9.1 Amendments to be Adopted Solely by General Partner. The General Partner (pursuant to the General Partner’s power of attorney from Limited Partners), without the consent of any Limited Partner, may amend any provision of this Agreement, and execute, swear to, acknowledge, deliver, file, and record whatever documents may be required in connection therewith, to reflect:

Notwithstanding the provisions of Sections 9.1 and 9.2 no provision of this Agreement that establishes a percentage of Limited Partners required to take any action shall be amended, altered, changed, repealed, or rescinded in any respect that would have the effect of reducing such voting requirement, unless

approved by written consent or the affirmative vote of Limited Partners whose aggregate Voting Percentage constitutes not less than the voting requirement sought to be reduced. Notwithstanding the provisions of Sections 9.1 and 9.2, any amendment to this Agreement that changes the allocation of Profits, Losses, distributions of the General Partner or any Limited Partner shall require the consent of the affected Partners. This Section 9.3 shall be amended only with the approval by written consent or affirmative vote of Limited Partners whose aggregate Voting Percentage constitutes 100% of the aggregate Voting Percentage of Limited Partners. The voting requirements contained in this Section 9.3 shall be in addition to voting requirements imposed by law or other provisions contained herein.

(e) Record Date. For the purpose of determining the Limited Partners entitled to notice of or to vote at any meeting of Limited Partners or any adjournment thereof, or Limited Partners entitled to receive payment of any distribution, or in order to make a determination of Limited Partners for any other purpose, the date on which notice of the meeting is mailed or the date on which the resolution declaring such distribution is adopted, as the case may be, shall be the record date for such determination of Limited Partners.

If a quorum is present, the affirmative vote of Limited Partners holding a Majority Interest shall be the act of the Limited Partners, unless the vote of a greater or lesser proportion or number is otherwise required by the Act or this Agreement. Unless otherwise expressly provided in this Agreement or required under applicable law, Limited Partners who have an interest (economic or otherwise) in the outcome of any particular matter upon which the Limited Partners vote or consent may vote or consent upon any such matter and their vote or consent, as the case may be, shall be counted in the determination of whether the requisite matter was approved by the Limited Partners.
