(a) If there is a net decrease in “partnership minimum gain” (as defined in Treasury Regulations § 1.704-2(d)), items of income and gain (determined in accordance with Treasury Regulations § 1.704-2(f)(6))) shall, to the extent required by the Treasury Regulations, be specially allocated to the Partners in an amount equal to each Partner’s share of the net decrease in partnership minimum gain (determined in accordance with Treasury Regulations § 1.704-2(g)). This Section 4.2(a) shall be applied consistently with, and subject to the exceptions contained in, the minimum gain chargeback requirements of Treasury Regulations § 1.704-2(f).

(b) If there is a net decrease in “partner nonrecourse debt minimum gain” (as defined in Treasury Regulations § 1.704-2(i)(2)), items of income and gain (determined in accordance with the provisions of Treasury Regulations § 1.704-2(i)(4)) shall, to the extent required by the Treasury Regulations, be specially allocated to the Partners in an amount equal to each Partner’s share of the net decrease in partner nonrecourse debt minimum gain (determined in accordance with the provisions of Treasury Regulations § 1.704-2(i)(5)). This Section 4.2(b) shall be applied consistently with, and subject to the exceptions contained in, the partner nonrecourse debt minimum gain chargeback requirements of Treasury Regulations § 1.704-2(i)(4).

(c) If a Partner unexpectedly receives any adjustment, allocation or distribution described in Treasury Regulations §§ 1.704-1(b)(2)(ii)(d)(4), (5) or (6), items of income and gain shall be specially allocated to the Partner in an amount and manner sufficient to eliminate, to the extent required by the Treasury Regulations, the deficit balance in the Partner’s Adjusted Capital Account as quickly as possible, provided that an allocation pursuant to this Section 4.2(c) shall be made only to the extent that the Partner has a deficit balance in its Adjusted Capital Account after all other allocations provided for in this Article IV have been tentatively made as if this Section 4.2(c) were not in this Agreement. This Section 4.2(c) shall be interpreted consistently with Treasury Regulations § 1.704-1(b)(2)(ii)(d).

(d) If a Partner has a deficit balance in its Capital Account at the end of any Fiscal Year that is in excess of the sum of (i) any amount it is obligated to restore pursuant to this Agreement and (ii) any amount the Partner is treated as obligated to restore pursuant to the penultimate sentences of Treasury Regulations §§ 1.704-2(g)(1) and 1.704-2(i)(5), items of income and gain in the amount of such excess shall be specially allocated to the Partner as quickly as possible, provided that an allocation pursuant to this Section 4.2(d) shall be made only to the extent that the Partner has a deficit balance in its Capital Account in excess of such amount after all other allocations provided for in this Article IV have been tentatively made as if Section 4.2(c) and this Section 4.2(d) were not in this Agreement.

(e) “Nonrecourse deductions” (as defined in Treasury Regulations § 1.704-2(c)) shall be specially allocated to the Partners in accordance with their respective Distribution Percentages.

(f) “Partner nonrecourse deductions” (as defined in Treasury Regulations § 1.704-2(i)(2)) shall be specially allocated to the Partners who bear the economic risk of loss for the liability to which those deductions are attributable, determined in accordance with the principles of Treasury Regulations § 1.704-2(i)(1).

(g) To the extent an adjustment to the adjusted tax basis of any Partnership asset under Code §§ 734(b) or 743(b) is required to be taken into account in determining Capital Accounts under Treasury Regulations § 1.704-1(b)(2)(iv)(m), the amount of the Capital Account adjustment shall be treated as an item of Income (if positive) or Loss (if negative) and shall be specially allocated to the Partners consistent with the manner in which their Capital Accounts are required to be adjusted by such Treasury Regulation.

(h) To the extent any allocation of Net Loss would cause or increase a deficit balance in a Limited Partner’s Adjusted Capital Account as of the end of the Fiscal Year for which the allocation is being made, the amount thereof shall instead be allocated to the General Partner.

(i) To minimize any distortions in the manner that the Partners would have shared distributions if the special allocations required by Sections 4.2(a)-(h) (the “Regulatory Allocations”) had not been part of this Agreement, the General Partner may specially allocate to the Partners offsetting items of Income or Loss so that the net amounts allocated to each Partner pursuant to Sections 4.1 and 4.2 (including specifically, Section 4.2(h)) will, to the extent reasonably possible, equal the net amounts that would have been allocated to each Partner pursuant to Section 4.1 if the Regulatory Allocations had never occurred. In exercising its authority hereunder, the General Partner shall consider any expected future Regulatory Allocations which are likely to offset other Regulatory Allocations previously made.

(a) To reflect the varying Interests of the Partners during any Fiscal Year, Net Income or Net Loss and items of Income and Loss shall be determined by the General Partner on a daily, monthly or other basis using any convention or method permitted under Code § 706 and the Treasury Regulations thereunder, provided that gain or loss arising from the sale or other disposition of any Partnership asset shall be allocated to the Persons who were Partners on the date of the sale or other disposition.

(b) Excess nonrecourse liabilities of the Partnership (as defined in Treasury Regulations § 1.752-3(a)(3)) shall be shared among the Partners in accordance with their respective Distribution Percentages.

(a) Except as provided in Section 4.4(b), for each Fiscal Year, items of income, gain, loss and deduction of the Partnership, determined solely for federal income tax purposes, shall be allocated to the Partners in the same manner as each correlative item of Income or Loss and Net Income or Net Loss is allocated to the Partners pursuant to Sections 4.1, 4.2 and 4.3.

(b) In accordance with § 704(c) of the Code and the Treasury Regulations thereunder, solely for federal income tax purposes, items of taxable income, gain, loss and deduction with respect to any Partnership asset having a Book Basis that differs from its adjusted basis for federal income tax purposes shall be allocated among the Partners in a manner that takes into account the amount of such difference at the time it arose. Such allocations shall be made pursuant to any method selected by the General Partner and permitted by Treasury Regulations § 1.704-3.

(c) Allocations pursuant to this Section 4.4 are solely for federal, state and local income tax purposes and shall not affect the Partners’ Capital Accounts.

4.5. Economic Terms to Prevail. The provisions contained in this Article IV are included to reflect the intentions of the Partners to maintain compliance with the Act and the Code. In the event the allocation provisions of this Article IV are inconsistent with the economic terms set forth herein, then it is agreed that the economic terms shall control.

Without limiting any other legal or equitable remedies of the Partnership, any distributions otherwise payable to the holder of an Interest received in a Transfer not made in accordance with the provisions of this Article VI but which the Partnership is required by law to recognize may be applied to satisfy any debts or liabilities (including for damages) that the transferor or transferee of the Interest may owe to the Partnership.

Notwithstanding any other provision of this Article VI, upon the death or legal incapacity of a Limited Partner who is a natural Person, the Limited Partner’s executor, administrator, guardian, conservator or other legal representative may exercise all of the Limited Partner’s rights and powers for the sole purpose of settling the Limited Partner’s estate or administering the Limited Partner’s property.

(b) Meetings of the Limited Partners to vote upon any matters on which the Limited Partners are authorized to take action under this Agreement or as the same may be amended from time to time may be called at any time by the General Partner or by a Majority Interest by delivering written notice, either in person or by certified mail, of such call to the General Partner. Within ten (10) days following receipt of such request, the General Partner shall cause a written notice to be given, either in person or by certified mail, to the Limited Partners entitled to vote advising them that a meeting, convenient to the Limited Partners, will be held at a time and place fixed by the General Partner.

Each Person (a “Pass-Through Partner”) that holds or controls an Interest as a Limited Partner on behalf of, or for the benefit of, another Person or Persons, or that is beneficially owned, directly or indirectly, by another Person or Persons, shall, within thirty (30) days following receipt from the tax matters partner of any notice, demand, request for information or similar document, convey that notice or other document in writing to all holders of beneficial interests in the Partnership holding such Interest through the Pass-Through Partner. The expenses of the tax matters partner shall be borne by the Partnership. If the Partnership is the subject of any audit or other administrative or judicial proceeding relating to taxes or tax or information returns of the Partnership, the tax matters partner is exclusively authorized to act for, and its decision shall be final and binding upon, the Partnership and each Partner.

All other tax elections available to the Partnership may be made in the sole discretion of the General Partner.

10.1. Withdrawal of Limited Partner. Except by reason of the transfer of all of its Interest to another Partner, the Partnership or a person admitted as a substituted Limited Partner pursuant to Section 6.5, a Limited Partner has neither the right nor the power to withdraw from the Partnership prior to the completion of its winding up.

10.2. Withdrawal of General Partner. Except as provided in Section 6.2(b), the General Partner has the right to withdraw as General Partner only with the consent of and upon such terms and conditions as have been approved by a Majority Interest.

(b) the bankruptcy, dissolution, termination of existence or occurrence of any other event of withdrawal of a General Partner described in Section 153.155 of the Act, unless (i) there remains at least one General Partner that continues the Partnership’s business, or (ii) within ninety (90) days after the event of withdrawal, a Majority Interest agree in writing to continue the Partnership’s business and to the appointment, effective as of the date of the withdrawal, of one or more new General Partners

(d) any other event that, under this Agreement or the Act, requires the winding up of the Partnership, except as otherwise provided herein.

10.4. Conversion of General Partner’s Interest. If pursuant to Section 10.3(b), the Partnership is continued and not dissolved upon the occurrence of an event of withdrawal of a General Partner, the Interest of the withdrawn General Partner shall automatically be converted to a special Limited Partner Interest effective as of the date of the event of withdrawal, with the same Capital Account and rights to participate in distributions and allocations pursuant to this Agreement as existed immediately before such conversion. Such conversion shall not release the former General Partner from any liabilities of the Partnership existing prior to such conversion nor prejudice any other rights or causes of action at law or in equity that the Partnership or the Limited Partners may have against the former General Partner as a result of any wrongful withdrawal. Following such conversion, the Partnership may withhold and retain the amount of any damages that result from a wrongful withdrawal by the former General Partner from any distributions that would otherwise be payable to the former General Partner under this Agreement.

10.5. Liquidation. Upon winding up of the Partnership, unless the Partnership is continued pursuant to the provisions of this Agreement, the General Partner (or a liquidating trustee selected by a Majority Interest) shall proceed with the winding up of the business and the liquidation of the Partnership as set forth under Article XI.

(a) In the event of the winding up of the Partnership in accordance with Section 10.3, unless the remaining Partners, if any, elect to continue the business of the Partnership as provided by the terms of this Agreement, the General Partner or the liquidating trustee of the Partnership shall proceed with the winding up of the affairs of the Partnership. Upon the winding up of the Partnership, no further business shall be conducted, except for such action as shall be necessary for the winding up of the affairs of the Partnership and the distribution of its assets to the Partners pursuant to the provisions of this Article XI. The General Partner or the liquidating trustee shall proceed diligently to wind up the affairs of the Partnership and make final distributions provided herein. The costs of liquidation shall be borne as a Partnership expense. Until final distribution and termination of the Partnership, any liquidating trustee shall continue to operate the Partnership with all the power and authority of the General Partner. The General Partner shall act as liquidating trustee or may appoint in writing one or more liquidating trustees who shall have full authority to wind up the affairs of the Partnership and to make final distribution as provided herein; provided, however, that if the Partnership is dissolved by an act which constitutes a breach of this Agreement by the General Partner, the Limited Partners shall, by a vote of the Majority Interest, designate a party to act as the liquidating trustee. The liquidating trustee may be a Partner so long as the Partner is not in breach of its obligations under this Agreement.

(b) Upon winding up of the Partnership, the General Partner or the liquidating trustee may sell any or all Partnership property, at the best cash price available or it may distribute those properties in kind.

(c) The General Partner or the liquidating trustee shall, to the extent a Partner’s Capital Account balance (as adjusted by Section 11.2) is not reduced to a negative number by virtue of a liquidating distribution pursuant to this Section 11.1(c) and the subsections of this Section 11.1(c) below, apply and distribute the assets of the Partnership as follows:

(i) First, to the payment and discharge of all of the Partnership’s debts and liabilities to creditors of the Partnership (including Limited Partners, except in respect of distributions), including all expenses of winding up and liquidation;

(ii) Second, to the payment and discharge of all of the Partnership’s debts and liabilities to the General Partner; and

(iii) Third, the balance, if any, to the General Partner and Limited Partners in accordance with their positive Capital Account balances, after giving effect to all contributions, distributions, and allocations for all periods, including the distributions under the foregoing provisions of this Section 11.1(c).

(d) If the General Partner or the liquidating trustee and a Majority Interest agree, a pro rata portion of the distributions that would otherwise be made to the General Partner and Limited Partners pursuant to Section 11.1(c) may be:

(i) distributed to a trust established for the benefit of the General Partner and Limited Partners for the purposes of liquidating Partnership assets, collecting amounts owed to the Partnership, and paying any contingent or unforeseen liabilities or obligations of the Partnership or of the General Partner arising out of or in connection with the Partnership. The assets of any such trust shall be distributed to the General Partner and Limited Partners from time to time, in the reasonable discretion of the General Partner or the liquidating trustee, in the same proportions as the amount distributed to such trust by the Partnership would otherwise have been distributed to the General Partner and Limited Partners pursuant to this Agreement; or

(ii) withheld to provide a reasonable reserve for Partnership liabilities (contingent or otherwise) and to reflect the unrealized portion of any installment obligations owed to the Partnership, provided that such withheld amounts shall be distributed to the General Partner and Limited Partners as soon as practicable.

11.2. Compliance with Timing Requirements of Regulations. In the event the Partnership is “liquidated” within the meaning of Section 1.704-1(b)(2)(ii)(g) of the Regulations, (a) distributions shall be made pursuant to this Article XI to the General Partner and Limited Partners who have positive Capital Accounts in compliance with Section 1.704-(b)(2)(ii)(b)(2) of the Regulations, and (b) if the General Partner’s Capital Account has a deficit balance (after giving effect to all contributions, distributions, and allocations for all taxable years, including the year during which such liquidation occurs), such General Partner shall contribute to the capital of the Partnership the amount necessary to restore such deficit balance to zero in compliance with Section 1.704-1(b)(2)(ii)(b)(3) of the Regulations. If any Limited Partner has a deficit balance in his Capital Account (after giving effect to all contributions, distributions and allocations for all taxable years, including the year during which such liquidation occurs), such Limited Partner shall have no obligation to make any contribution to the capital of the Partnership with respect to such deficit, and such deficit shall not be considered a debt owed to the Partnership or to any other Person for any purpose whatsoever.

11.3. Deemed Distribution and Recontribution. Notwithstanding any other provision of this Article XI, in the event the Partnership is liquidated within the meaning of Section 1.704-1(b)(2)(ii)(g) of the Regulations but it has not wound up pursuant to Section 10.3, the Partnership shall not be liquidated, the Partnership’s liabilities shall not be paid or discharged,

and the Partnership’s affairs shall not be wound up. Instead, the Partnership shall be deemed to have distributed the property in kind to the General Partner and Limited Partners, who shall be deemed to have assumed and taken such property subject to all Partnership liabilities, all in accordance with their respective Capital Accounts. Immediately thereafter, the General Partner and Limited Partners shall be deemed to have recontributed the property in kind to the Partnership, which shall be deemed to have assumed and taken such property subject to all such liabilities.

11.4. Certificate of Termination. Upon completion of the distribution of Partnership assets as provided herein, the Partnership shall be terminated, and the General Partner or the liquidating trustee shall cause the filing with the Secretary of State of a certificate of termination and take such other actions as may be necessary to terminate the Partnership.

Each Partner who is not a natural Person represents to each of the other Partners and the Partnership that (a) the Partner is and will remain duly organized and validly existing under the applicable laws of its state of organization, (b) the Partner is and will remain qualified to do business and in good standing in all jurisdictions in which the nature of its business or the ownership of its assets makes such qualification necessary, (c) the Partner has all requisite power and authority to enter into this Agreement, (d) the execution, delivery and performance of this Agreement by the Partner have been duly authorized by all necessary action, (e) this Agreement is the legal, valid and binding obligation of the Partner, enforceable in accordance with its terms (except as limited by applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally), and (f) the execution, delivery and performance of this Agreement by the Partner does not and will not violate, conflict with or constitute a default under (i) the Partner’s governing documents, (ii) any instrument or agreement to which it is a party or by which any of its assets are bound, or (iii) any law, rule, regulation, order, writ, judgment, decree, determination or award applicable to the Partner or its assets.

12.2. Securities Laws. Each Limited Partner represents to each of the other Partners and the Partnership that (a) it is acquiring its Interest as a principal and for its own account, for investment purposes only and not with a view to, or for sale in connection with, any distribution of such Interest, nor with any present intention of distributing or selling such Interest, (b) it will not Transfer, or attempt to Transfer, its Interest or any part thereof in violation of the Securities Act, or any other applicable federal or state securities law, (c) it has been advised that (i) the issuance of an Interest to it has not been registered with the Securities and Exchange Commission under the Securities Act or registered with any state agency under applicable state securities laws, in reliance upon an exemption from such registration, and (ii) it must bear the economic risk of the acquisition of the Interest for an indefinite period of time because it may not offer, sell, Transfer or otherwise dispose of the Interest unless the offer, sale, Transfer or other disposition has been registered under the Securities Act and any applicable state securities laws or, in the opinion of counsel (acceptable to the General Partner), such offer, sale, Transfer or other disposition is otherwise exempt from registration under the Securities Act and applicable

state securities laws, and otherwise complies with the restrictions on Transfer set forth in this Agreement, and (d) it understands that the Partnership is under no obligation to register the offer, sale, Transfer or other disposition of the Interest or to take any other action necessary in order to make compliance with an exemption from registration available.

12.4. ERISA. Each Partner represents to each of the other Partners and the Partnership that (a) it is not acquiring and has not acquired its Interest with assets of an employee benefit plan subject to Title I of ERISA, and (b) its acquisition and holding of its Interest pursuant to this Agreement will not result in or create a “prohibited transaction,” as defined in § 4975(c) of the Code, cause the Partnership to be a “disqualified Person,” as defined in § 4975(e)(2) of the Code, or a “party in interest,” as defined in § 3(14) of ERISA.

12.5. Survival; Indemnity. The representations and warranties of each Partner pursuant to this Article XII shall survive the execution and delivery of this Agreement and the consummation of the transactions contemplated hereby, and shall continue in effect indefinitely thereafter.

13.2. Duration; Reliance. The power of attorney granted in Section 13.1 shall be deemed to be coupled with an interest and irrevocable, and shall survive an assignment by a Limited Partner of all or part of its Interest (except that if the assignee is admitted as a Limited Partner, the power of attorney shall survive the delivery of such assignment for the sole purpose of enabling such attorney-in-fact to execute, acknowledge, swear to and file any agreement, certificate, instrument or document necessary to effect such admission), and the death, incompetency or termination of existence of the Limited Partner. Any Person dealing with the Partnership may conclusively presume and rely upon the fact that any document executed by the attorney and agent herein appointed is regular and binding without further inquiry.
