b)Member Minimum Gain Chargeback. Notwithstanding any other provision of this Article 8 except Section 8.3(a), if there is a net decrease in Member Nonrecourse Minimum Gain attributable to a Member Nonrecourse Debt during any Allocation Year, each Member who has a share of the Member Nonrecourse Minimum Gain attributable to such Member Nonrecourse Debt, determined in accordance with Regulations Section 1.704 -2(i)(5), shall be specially allocated items of Company income and gain for such Allocation Year (and, if necessary, subsequent Allocation Years) to the extent required and in the manner provided by Regulations Section 1.704 -2(i)(4). This Section 8.3(b) shall be interpreted and applied in such a manner as to comply with the minimum gain chargeback requirement in Regulations Section 1.704 -2(i)(4).

c)Qualified Income Offset. In the event any Member unexpectedly receives any adjustments, allocations, or distributions described in Section 1.704 -1(b)(2)(ii)(d)(4), Section 1.704 -1(b)(2)(ii)(d)(5), or Section 1.704 -1(b)(2)(ii)(d)(6) of the Regulations, items of Company income and gain shall be specially allocated to each such Member in an amount and manner sufficient to eliminate, to the extent required by the Regulations, the Adjusted Capital Account Deficit of such Member as quickly as possible, provided that an allocation pursuant to this Section 8.3(c) shall be made only if and to the extent that such Member would have an Adjusted Capital Account Deficit after all other allocations provided for in this Article 8 have been tentatively made as if this Section 8.3(c) were not in the Agreement.

d)Gross Income Allocation. In the event any Member has a deficit Capital Account at the end of any Allocation Year, or in the event any Member would have a deficit Capital Account in connection with the receipt of distributions made to the Member in accordance with Section 11.3.1(c), which is in excess of the sum of (i) the amount such Member is obligated to restore pursuant to any provision of this Agreement, and (ii) the amount such Member is deemed to be obligated to restore pursuant to the penultimate sentences of Sections 1.704 -2(g)(1) and 1.704 -2(i)(5) of the Regulations, each such Member shall be specially allocated items of Company income and gain in the amount of such excess as quickly as possible, provided that an allocation pursuant to this Section 8.3(d) shall be made only if and to the extent that such Member would have a deficit Capital Account in excess of such sum after all other allocations provided for in this Article 8 have been made as if Section 8.3(c) and this Section 8.3(d) were not in the Agreement.

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

f)Nonrecourse Deductions. Nonrecourse Deductions for any Allocation Year shall be specially allocated among the Members in proportion to their Percentage Interests.

15

---

such gain or loss shall be allocated to the Members in a manner consistent with the manner in which their Capital Accounts are required to be adjusted pursuant to Regulations Section 1.704 -1(b)(2)(iv)(m).

h)Taxable Issuances of Membership Interests. Any income, gain, loss, or deduction realized as a direct or indirect result of the issuance of an Interest by Company to a Member (Issuance Items) shall be allocated among the Members so that, to the extent possible, the net amount of such Issuance Items, together with all other allocations under this Agreement to each Member, shall be equal to the net amount that would have been allocated to each such Member if the Issuance Items had not been realized.

SECTION 8.4CURATIVE ALLOCATIONS. The allocations set forth above in Section 8.2.2 and Sections 8.3(a) to 8.3(g) (Regulatory Allocations) are intended to comply with certain requirements of the Regulations. It is the intent of the Members that, to the extent possible, all Regulatory Allocations shall be offset either with other Regulatory Allocations or with special allocations of other items of Company income, gain, loss or deduction pursuant to this Section 8.4. Therefore, notwithstanding any other provision of this Article 8 (other than the Regulatory Allocations), the Members shall make such offsetting special allocations of Company income, gain, loss or deduction in whatever manner it determines appropriate 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 the Agreement and all Company items were allocated pursuant to Section 8.1, Section 8.2.1 and Section 8.3(h) . In exercising their discretion under this Section 8.4, the Members shall take into account future Regulatory Allocations under Sections 8.3(a) and (b) that, although not yet made, are likely to offset other Regulatory Allocations previously made under Section 8.3(e) and (f).

SECTION 8.5OTHER ALLOCATION RULES.

8.5.1Application of Section 8.3. The special allocations provided in Section 8.3 are intended to comply with the provisions of Regulation Section 1.704 -2 and are to be interpreted and applied to accomplish that result;provided, however, that to the extent possible, the special allocations shall be taken into account in allocating items of income, gain, loss, and deduction among the Members in such a manner that the net amount of the allocations to each Member shall be the same as such Members distributive shares of Profit and Losses would have been had the events requiring the special allocations not occurred. The Members shall have reasonable discretion to apply the provisions of Section 8.3 in whatever order is likely to minimize the economic distortions that otherwise might result from the application of the special allocation provisions;provided, however, that the Members shall apply the special allocations in the order set forth in Section 8.3 to the extent that doing so does not have a material adverse effect on the Members.

8.5.2Timing of Allocations. Profits, Losses and any other items of income, gain, loss or deduction shall be allocated to the Members pursuant to this Article 8 as of the last day of each Fiscal Year;provided, however, that Profits, Losses and such other items shall also be allocated at such times as the Gross Asset Values of Company Property are adjusted pursuant to subparagraph (ii) of the definition of Gross Asset Value.

8.5.4Acknowledgment of Tax Consequences. Each Member hereby acknowledges awareness of the tax consequences of the allocations made by this Article 8 and agrees to be bound by the provisions of this Article 8 in reporting their shares of Company income and loss for income tax purposes, except to the extent otherwise required by Law.

8.5.5Excess Nonrecourse Liabilities. Solely for purposes of determining the Members proportionate shares of the excess nonrecourse liabilities of Company within the meaning of Regulations Section 1.752 -3(a)(3), the Members interests in Profits shall be in proportion to their Percentage Interests.

8.5.6Distribution of Certain Proceeds. To the extent permitted by Regulations Section 1.704 -2(h)(3), the Members shall endeavor not to treat distributions of cash as having been made from the proceeds of a Nonrecourse Liability or a Member Nonrecourse Debt, but only to the extent that such distributions would cause or increase an Adjusted Capital Account Deficit for any Member.

8.5.7Safe Harbor Election. In the event the Tax Matters Member makes the election contemplated by Section 10.3.2, Profits and Losses shall be allocated in a manner that satisfies the requirements for such election, including any forfeiture allocations required by proposed Section 1.704 -1(b)(4)(xii)(b)(1) of the Regulations and the revenue procedure contemplated by Internal Revenue Service Notice 2005-43 (or the corresponding provisions of any final Regulations and associated guidance by the Treasury Department and the Internal Revenue Service regarding the tax consequences associated with the issuance or transfer of Membership Rights in exchange for the performance of services).

SECTION 8.6TAX ALLOCATIONS: SECTION 704(c). In accordance with Code Section 704(c) and the Regulations thereunder, income, gain, loss, and deduction with respect to any property contributed to the capital of Company shall, solely for federal income tax purposes, be allocated among the Members so as to take account of any variation between the adjusted basis of such property to Company for federal income tax purposes and its initial Gross Asset Value (computed in accordance with subparagraph (i) of the definition of Gross Asset Value). In the event the Gross Asset Value of any Company asset is adjusted pursuant to subparagraph (ii) of the definition of Gross Asset Value, 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 its Gross Asset Value in the same manner as under Code Section 704(c) and the Regulations thereunder. Any elections or other decisions relating to such allocations shall be made by the Members in any manner that reasonably reflects the purpose and intention of this Agreement. Allocations pursuant to this Section 8.6 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 Capital Account or share of Profits, Losses, other items, or distributions pursuant to any provisions of this Agreement. Except



17

as otherwise provided in this Agreement, all items of Company income, gain, loss, deduction, and any other allocations not otherwise provided for shall be divided among the Members in the same proportions as they share Profits or Losses, as the case may be, for the Allocation Year.

If it is determined, by a court of competent jurisdiction, that Company has dissolved prior to the occurrence of a Dissolution Event, or upon the occurrence of an event specified in Section 11.1(d), then within an additional ninety (90) Days after such determination (the Reconstitution Period), a Required Interest may elect to reconstitute Company and continue its business on the same terms and conditions set forth in this Agreement by forming a new limited liability company on terms identical to those set forth in this Agreement;provided, however, that the right of a Required Interest to reconstitute and continue the business of Company shall not exist and may not be exercised unless Company has received an opinion of counsel that the exercise of the right would not result in the loss of limited liability of any Member and neither Company nor the reconstituted limited liability company would cease to be treated as a partnership for federal income tax purposes upon the exercise of such right to continue. Unless such an election is made within the Reconstitution Period, Company shall liquidate and wind up its affairs in accordance with Section 11.3.

SECTION 11.3WINDING UP.

11.3.1General.

23

---

purposes of winding up its affairs in an orderly manner, liquidating its assets, and satisfying the claims of its creditors and Members, and no Member shall take any action that is inconsistent with, or not necessary to or appropriate for, the winding up of Companys business and affairs,providedthat all covenants contained in this Agreement and obligations provided for in this Agreement shall continue to be fully binding upon the Members until such time as Company Property has been distributed pursuant to this Section 11.3 and Company has been dissolved pursuant to the TBOC. The Liquidator shall be responsible for overseeing the winding up and dissolution of Company, which winding up and dissolution shall be completed as soon as reasonably possible following the occurrence of the Dissolution Event and within ninety (90) Days after the last day on which Company may be reconstituted pursuant to Section 11.2.

(a)      First, to creditors (including Members, to the extent permitted by Law) in satisfaction of all of Companys debts and other liabilities (whether by payment or the making of reasonable provision for payment thereof), other than liabilities for which reasonable provision for payment has been made and liabilities for distribution to Members under Section 18-601 or Section 18-604 of the TBOC;

(b)      Second, except as provided in this Agreement, to Members and former Members of Company in satisfaction of liabilities for distribution arising under Section 18-601 or Section 18-604 of the TBOC; and

11.3.3Final Allocations. The Members intend that the allocations provided under Article 8 will produce final Capital Account balances for the Members such that liquidating distributions pursuant to Sections 11.3.1(c) or 11.4 are made in accordance with such Capital Account balances. If the allocations otherwise made under Article 8 would fail to produce such final Capital Account balances, the Members shall have the power and authority to cause the allocations made under Article 8 to be made in a manner that achieves the foregoing intent as close as possible.

SECTION 11.4COMPLIANCE WITH CERTAIN REQUIREMENTS. In the event Company is liquidated within the meaning of Regulations Section 1.704 -1(b)(2)(ii)(g), distributions shall be made to the Members in accordance with their Percentage Interests.

discretion of the Liquidator, a pro rata portion of the distributions that would otherwise be made to the Members pursuant to this Article 11 may be:

(a)      Distributed to a trust established for the benefit of the Members for the purposes of liquidating Company assets, collecting amounts owed to Company, and paying any contingent or unforeseen liabilities or obligations of Company. The assets of any such trust shall be distributed to the Members from time to time, in the reasonable discretion of the Liquidator, in the same proportions as the amount distributed to such trust by Company would otherwise have been distributed to the Members pursuant to Section 11.3 hereof; or

(b)      Withheld to provide a reasonable reserve for Company liabilities (contingent or otherwise) and to reflect the unrealized portion of any installment obligations owed to Company, provided that such withheld amounts shall be distributed to the Members as soon as practicable.

The portion of the distributions that would otherwise have been made to each of the Members that is instead distributed to a trust pursuant to Section 11.4(a) or withheld to provide a reserve pursuant to Section 11.4(b) shall be determined in the same manner as the expense or deduction would have been allocated if Company had realized an expense equal to such amounts immediately prior to distributions being made pursuant to Section 11.3.

SECTION 11.5DEEMED RECONSTITUTED COMPANY. In the event Company is liquidated within the meaning of Section 1.704 -1(b)(2)(ii)(g) of the Regulations, but no Dissolution Event has occurred, Company Property shall not be liquidated, Companys liabilities shall not be paid or discharged, and Companys affairs shall not be wound up.

SECTION 11.6RIGHTS OF MEMBERS. Except as otherwise provided in this Agreement, each Member shall look solely to Company Property for the return of its Capital Contribution and has no right or power to demand or receive Company Property other than cash.

SECTION 11.7NOTICE OF DISSOLUTION/TERMINATION.

(a)      In the event a Dissolution Event occurs or an event occurs that would, but for provisions of Section 11.2, result in a dissolution of Company, Company shall, within thirty (30) Days thereafter, provide written notice thereof to each of the Members and to all other parties with whom Company regularly conducts business (as determined in the discretion of the Members), the Members shall publish, or cause to be published, notice thereof in a newspaper of general circulation in each place in which Company regularly conducts business (as determined in the discretion of the Members).21
