Section 5.3. Duties and Services of the General Partner. The General Partner shall comply in all respects with the terms of this Agreement. In the conduct of the business and operations of the Partnership, the General Partner shall (i) use the care of an ordinarily prudent business Person to cause the Partnership (1) to comply with the terms and provisions of all agreements to which the Partnership is a party or to which its properties are subject, (2) to comply with all applicable laws, ordinances or governmental rules and regulations to which the

Partnership is subject and (3) to obtain and maintain all licenses, permits, franchises and other governmental authorizations necessary with respect to the ownership of Partnership properties and the conduct of the Partnership’s business and operations and (ii) attend to other day-to-day affairs of the Partnership in a manner which is in the best interests of the Partnership. The General Partner shall be obligated to perform the duties, responsibilities and obligations of the General Partner hereunder only to the extent that funds of the Partnership are available therefor.

Section 5.4. Liability of Partners and Indemnification.

(a) The General Partner, the Limited Partners and their Affiliates, and their partners, officers, directors, employees and agents, shall not be liable, responsible or accountable in damages or otherwise to the Partnership or the other Partners for any acts or omissions that do not constitute gross negligence, willful misconduct or a breach of the express terms of this Agreement or for transactions from which such person derived an improper personal benefit (which shall not include any benefit permitted by Section 5.7(b) or any other provision of this Agreement), and the Partnership shall indemnify and save harmless the General Partner, the Partners and their Affiliates, and their partners, officers, directors, employees and agents (individually an “Indemnitee”) from all liabilities for which indemnification is not prohibited by Delaware law, in each case to the extent that any such liability in any way relates to or arises out of or is alleged to relate to or arise out of any act or omission on the part of the Partnership, or the Indemnitee acting on behalf of the Partnership, for which the Indemnitee is not to be held accountable or otherwise liable under this Agreement. Any act or omission performed or omitted by an Indemnitee on advice of legal counsel or an independent consultant who has been employed or retained by the Partnership shall be presumed to have been performed or omitted in good faith without gross negligence or willful misconduct. THE PARTIES RECOGNIZE THAT THIS PROVISION SHALL RELIEVE ANY SUCH INDEMNITEE FROM ANY AND ALL LIABILITIES, OBLIGATIONS, DUTIES, CLAIMS, ACCOUNTS AND CAUSES OF ACTION WHATSOEVER ARISING OR TO ARISE OUT OF ANY ORDINARY NEGLIGENCE BY ANY SUCH INDEMNITEE, AND SUCH INDEMNITEE SHALL BE ENTITLED TO INDEMNIFICATION FROM ACTS OR OMISSIONS THAT MAY CONSTITUTE ORDINARY NEGLIGENCE.

(b) The Partnership shall, except as prohibited by Delaware law, pay or reimburse expenses incurred by an Indemnitee in connection with (i) the Indemnitee’s appearance as a witness or other participation in a proceeding involving or affecting the Partnership at a time when the Indemnitee is not a named defendant or respondent in the proceeding, or (ii) the Indemnitee’s other indemnity rights under this Agreement, in advance of the final disposition of any proceeding, within thirty (30) days of the receipt by the Partnership from the Indemnitee of (x) a written request for such reimbursement and (y) in the case of a request pursuant to clause (ii), a signed statement that the Indemnitee is not accountable or otherwise liable under this Agreement for the losses alleged and will promptly reimburse the Partnership for the advances if it ultimately is found not to be entitled to the advances. If a claim is not paid in full by the Partnership within thirty (30) days after a written claim has been received by the Partnership, the Indemnitee may at any time thereafter bring suit against the Partnership to recover the unpaid amount of the claim and, if successful in whole or in part, the Indemnitee shall be entitled to be paid also the expense of prosecuting such claim. Neither the failure of the Partnership (including the General Partner, independent legal counsel, or the Limited Partners) to have made a

determination that indemnification of the Indemnitee is permissible in the circumstances because the Indemnitee has met the applicable standard of conduct, if any, nor an actual determination by the Partnership (including its General Partner, independent legal counsel, or its Limited Partners) that the Indemnitee has not met the standard of conduct, shall be a defense to the action or create a presumption that the Indemnitee has not met the standard of conduct.

(c) The General Partner shall have the right to require that any contract entered into by the Partnership provide that the General Partner shall have no personal liability for the obligations of the Partnership thereunder.

(d) The indemnification provided by this Section 5.4 shall be in addition to any other rights to which each Indemnitee may be entitled under any agreement or vote of the Partners, as a matter of law or otherwise, both as to action in the Indemnitee’s capacity as a Partner or an officer, director, employee or agent of a Partner or as a Person serving at the request of the Partnership as set forth above and to action in another capacity, and shall continue as to an Indemnitee who has ceased to serve in such capacity and shall inure to the benefit of the heirs, successors, assigns, administrators and personal representatives of the Indemnitees.

(e) In no event may an Indemnitee subject the Limited Partners to personal liability by reason of this indemnification provision.

(f) An Indemnitee shall not be denied indemnification in whole or in part under this Section 5.4 because the Indemnitee 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.

Section 5.5. Other Matters Concerning General Partner.

(a) The General Partner may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, debenture or other paper or document believed by it to be genuine and to have been signed or presented by the proper Person or Persons and any act taken or omitted in reliance upon any such paper or documents shall be conclusively presumed to have been done or omitted in good faith.

(b) The General Partner may consult with legal counsel, accountants, appraisers, management consultants, investment bankers and other consultants and advisers selected by it, and any act taken or omitted in reliance upon the opinion or advice of any such Person as to matters that the General Partner reasonably believes to be within such Persons’ professional or expert competence (including, without limitation, any opinion of legal counsel to the effect that the Partnership would “more likely than not” prevail with respect to any matter) shall be conclusively presumed to have been done or omitted in good faith and in accordance with such opinion or advice.

(c) The General Partner shall have the right, in respect of any of its powers or obligations hereunder, to act through a duly appointed attorney or attorney-in-fact. Each such attorney or attorney-in-fact shall, to the extent provided by the General Partner in the power of

attorney, have full power and authority to do and perform each and every act and duty which is permitted or required to be done by the General Partner hereunder.

Section 5.6. Duties of the Partners, Directors and Officers.

(a) Except as otherwise expressly provided in this Agreement, none of the Limited Partners, the General Partner or any of their respective officers or Affiliates shall, to the fullest extent permitted by Section 17.1101(d) of the Act, have any duties (whether fiduciary, quasi-fiduciary or otherwise and whether existing by statute, in equity, at common law or otherwise) or obligations whatsoever, by virtue of the relationships established pursuant to this Agreement, to take or refrain from taking any action that may impact the Partnership, the General Partner, any Limited Partner or any of their respective Affiliates.

(b) The provisions of this Agreement, including this Article V, to the extent they restrict the fiduciary and other duties and liabilities of a Person otherwise existing at law or in equity, constitute an agreement to restrict and replace such fiduciary and other duties and liabilities of such Person under Section 17-1101(d) of the Act, it being agreed and understood that the provisions of this Agreement, including this Article V, shall not restrict or replace any duties (whether fiduciary, quasi-fiduciary or otherwise and whether existing by statute, in equity, at common law or otherwise) or obligations of the Limited Partners, the General Partner, or their respective officers or Affiliates not arising by virtue of the relationships established pursuant to this Agreement. To the extent that, at law or in equity, a Limited Partner, the General Partner or any of their respective officers has duties (including fiduciary duties) and liabilities relating thereto to the Partnership, to a Limited Partner, to the General Partner or to any other Person that is a party to or is otherwise bound by this Agreement, such Limited Partner, General Partner, or officer shall not be liable to the Partnership, to any Limited Partner, to the General Partner or to any other Person that is a party to or is otherwise bound by this Agreement for its reliance on the provisions of this Agreement.

Section 5.7. Contracts with Affiliates; Other Businesses.

(a) The Partnership may enter into contracts and agreements with any Partner and/or any of its Affiliates for the rendering of services and the sale and lease of supplies and equipment on such arm’s-length terms that (a) are no less favorable to the Partnership than those available from unrelated third Persons and (b) are approved by the General Partner. No such contract or agreement shall be void or voidable solely for such reason and no Person having an interest in any such transaction shall have any liability to the Partnership or any Partner solely by virtue of such relationship or conflict.

(b) The General Partner and each Affiliate thereof (including without limitation any director, officer, partner, member, manager, employee, agent or representative of the General Partner or any Affiliate thereof) may have business interests and engage in business activities in addition to those relating to the Partnership, including without limitation interests in and activities related to the businesses described in Section 1.3 or otherwise competitive with the business of the Partnership and neither the Partnership nor any other Partners shall have any rights in such other business interests or activities or in any income or profits therefrom.

Section 5.8. Resolution of Conflicts of Interest.

(a) Unless otherwise expressly provided herein, (i) whenever a potential conflict of interest exists or arises between the General Partner or any of its Affiliates, on the one hand, and the Partnership, or Limited Partner or assignee on the other hand, or (ii) whenever this Agreement or any other agreement contemplated herein provides that the General Partner shall act in a manner which is, or provide terms which are, fair and reasonable to the Partnership, or any Limited Partner or assignee, the General Partner shall resolve such conflict of interest, take such action or provide such terms, considering in each case (A) the relative interests of each party (including its own interests) to such conflict, agreement, transaction or situation and the benefits and burdens relating to such interests, (B) any customary or accepted industry practices and any customary or historical dealings with a particular Person, (C) any applicable generally accepted accounting practices or principles and (D) such additional factors as the General Partner determines in its sole discretion to be relevant, reasonable or appropriate under the circumstances. Any resolution, action or terms so made, taken or provided by the General Partner in respect of such conflict of interest shall not constitute a breach of this Agreement, any other agreement contemplated herein or any duty stated or implied by law or equity (including fiduciary duties), so long as such action or decision is taken in a manner consistent with the provisions of this Article V.

(b) Whenever in this Agreement the General Partner is permitted or required to make a decision (i) in its “sole discretion” or “discretion,” or under a similar grant of authority or latitude, the General Partner shall be entitled to consider only such interests and factors as it desires and shall have no duty or obligation to give any consideration to any interest of or factors affecting the Partnership, the Limited Partners or the assignees, or (ii) in its “good faith” or under another express standard, the General Partner shall act under such express standard and shall not be subject to any other or different standards imposed by this Agreement or any other agreement contemplated herein or therein. Each Limited Partner or assignee hereby agrees that any standard or care or duty imposed in this Agreement or any other agreement contemplated herein or under the Act or any other applicable law, rule or regulation shall be modified, waived or limited in each case as required to permit the General Partner to act under this Agreement or any other agreement contemplated herein and to make any decision pursuant to the authority prescribed in this Section 5.8(b) so long as such action or decision does not constitute willful misconduct and is reasonably believed by the General Partner to be consistent with the overall purposes of the Partnership.

Section 5.9. Reimbursement of Expenses. The Partnership shall pay or reimburse the General Partner for all reasonable direct and indirect costs incurred by the General Partner in managing and conducting the business and affairs of the Partnership, including, without limitation, (a) all costs and expenses incurred in any business of the Partnership, (b) secretarial, telephone, office rent and other office expenses, (c) salaries and other compensation expenses of employees, officers and directors, (d) other administrative expenses, (e) travel expenses, (f) legal and accounting costs and expenses and (g) expenses incurred in providing or obtaining such other professional, technical, and administrative services and advice as the General Partner may deem necessary or desirable. Subject to Section 5.7, the General Partner may utilize the services of any of its Affiliates in the course of conducting the business and affairs of the Partnership, and the Partnership may pay, and any such Affiliate shall be entitled to receive, a reasonable fee for

any services performed at the request of the General Partner for the Partnership. The General Partner shall determine in good faith which expenses are allocable to the Partnership in a manner which is fair and reasonable to the General Partner and the Partnership.

Section 5.12. Tax Matters Partner. The Partners designate the General Partner to be the “tax matters partner” of the Partnership pursuant to Section 6231(a)(7) of the Code. The Partners may change the Partner who is designated the tax matters partner at any time. The Partner who is the tax matters partner shall take such action as may be necessary to cause each other Partner to become a “notice partner” within the meaning of Section 6223 of the Code. Such Partner shall inform each other Partner of all significant matters that may come to its attention in its capacity as tax matters partner by giving notice thereof on or before the fifth (5^th) Business Day after becoming aware thereof and, within that time, shall forward to each other Partner copies of all significant written communications it may receive in that capacity. Any Partner who is designated as tax matters partner may not take any action contemplated by Sections 6222 through 6232 of the Code without the consent of the other Partners, and may not in any case take any action left to the determination of an individual Partner under Sections 6222 through 6232 of the Code.

Section 5.13. Withdrawal by the General Partner. The General Partner shall not voluntarily withdraw from the Partnership unless the Required Percentage of the Class A Limited Partners consent to such withdrawal. In the event that the Required Percentage of the Class A Limited Partners shall consent to the withdrawal of the General Partner, the General Partner shall not be deemed to be liable with respect to any debts or liabilities that the Partnership incurs subsequent to the date of withdrawal, provided that such withdrawal shall not diminish or in any way affect the liability of the General Partner with respect to any debts or liabilities that the Partnership incurred prior to such date.

The Partners calling for a meeting of the Partners must sign the notice for the meeting.

(c) Any notice required to be given to any Partner under this Agreement or the Act may be waived in writing by that Partner (whether before, at, or after the meeting). A Partner’s attendance at a meeting also shall constitute a waiver of any required notice of the meeting, unless that Partner at the beginning of the meeting objects to holding the meeting or transacting particular business at the meeting. Any action taken at a meeting at which proper notice was not given to all of the Partners or which all of the Partners did not waive such notice requirement shall be null and void and of no effect whatsoever.

Any such proxy shall be filed with the General Partner before or at the time of the meeting. No proxy shall be valid after 11 months from the date of its execution, unless otherwise validly provided in the proxy.

(g) Any one or more Partners may participate in a meeting of the Partners by means of a conference telephone or similar communication device that allows all persons participating in the meeting to simultaneously hear each other during the meeting, and such participation in the meeting shall be the equivalent of being present in person at such meeting.

The written consents may be executed in counterparts. Action taken by written consent shall be effective when the Partners needed to approve the action have signed the proposed written consent or counterpart thereof, unless the written consent specifies that it is effective as of an earlier or later date. A written consent has the same force and effect as if such matter was voted upon at a duly called meeting of the Partners and may be described as such in any document or instrument.

(i) The General Partner at its election may separately inform and consult with the Limited Partners without the necessity of calling and/or holding a meeting of the Limited Partners.

(j) Notwithstanding the foregoing provisions of this Section 7.3, the Limited Partners shall not be permitted to take part in the business or control of the business of the Partnership.

Section 7.4. Confidentiality. No Partner shall use, publish, disseminate or otherwise disclose, directly or indirectly, any Confidential Information that should come into the possession of such Partner for other than a proper Partnership purpose. No Partner shall disclose any such Confidential Information except as expressly authorized by this Agreement or by the General Partner, or as required by law or governmental or regulatory authority. Each Partner shall instruct all Affiliates (including their representatives, agents and counsel) to comply with this Section 7.4. If a Partner is required by law or court order to disclose information that would otherwise be Confidential Information under this Agreement, such Partner shall immediately notify the General Partner of such notice and provide the General Partner the opportunity to resist such disclosure by appropriate proceedings.

(c) the occurrence of an event of withdrawal from the Partnership by the General Partner as provided for in this Agreement or the Act;

(d) the consent in writing of the General Partner (subject to the express terms and conditions of its limited liability company agreement) and the Required Percentage of the Class A Limited Partners; or

(e) the occurrence of any event which, under the Act, causes the dissolution of a limited partnership.

Notwithstanding anything contained to the contrary in this Section, if a dissolution of the Partnership would otherwise occur due to the occurrence of an event of dissolution under Section 8.1(c), the Partnership may be reconstituted if within ninety (90) days of such event of dissolution the Required Percentage of the Class A Limited Partners agree in writing to continue the business of the Partnership and agree to the appointment, effective as of the date of such event of dissolution of one or more new General Partners (“New General Partner”). In the event the Required Percentage of the Class A Limited Partners appoint a New General Partner of the Partnership, the Partnership interest held by the former General Partner shall be converted into a Class A Partnership Interest and the former General Partner shall be treated as a Class A Limited Partner for all purposes of this Agreement. If a New General Partner is appointed by the Required Percentage of the Class A Limited Partners and such New General Partner is not an existing Partner, such New General Partner shall be admitted to the Partnership and the Percentage Interest of each Class A Limited Partner, including the former General Partner, shall be reduced proportionately to create the Percentage Interest of the New General Partner, and this Agreement shall be amended by the Required Percentage of the Class A Limited Partners to reflect the new Percentage Interests of the Class A Limited Partners and the admission of the New General Partner.

Section 8.2. Liquidation and Termination. Upon dissolution of the Partnership, unless reconstituted pursuant to the Act, the General Partner or, if the withdrawal of the General Partner caused the dissolution of the Partnership, a Person selected by the Required Percentage of the Class A Limited Partners, shall act as liquidator or shall appoint one or more liquidators who shall have full authority to wind up the affairs of the Partnership and make final distributions as provided herein. The liquidator shall continue to operate the Partnership properties with all of the power and authority of the General Partner. The steps to be accomplished by the liquidator are as follows:

(a) As promptly as possible after dissolution and again after final liquidation, the liquidator, if requested by any Partner, shall cause a proper accounting to be made by the Partnership’s independent accountants of the Partnership’s assets, liabilities and operations through the last day of the month in which the dissolution occurs or the final liquidation is completed, as appropriate.

(b) The liquidator shall pay all of the debts and liabilities of the Partnership (including all expenses incurred in liquidation) or otherwise make adequate provision therefor (including without limitation the establishment of a cash escrow fund for contingent liabilities in such amount and for such term as the liquidator, with the consent of the Required Percentage of

the Class A Limited Partners, may reasonably determine). After making payment or provision for all debts and liabilities of the Partnership, the liquidator shall sell all properties and assets of the Partnership for cash as promptly as is consistent with obtaining the best price therefor; provided, however, that upon the consent of the Required Percentage of the Class A Limited Partners, the liquidator may distribute such properties in kind. All gain, loss, and amount realized on such sales shall be allocated to the Partners as provided in Exhibit B, and the Capital Accounts of the Partners shall be adjusted accordingly. In the event of a distribution of properties in kind, the liquidator shall first adjust the Capital Accounts of the Partners as provided in Exhibit B by the amount of any gains or losses that would have been recognized by the Partners if such properties had been sold. The liquidator shall then distribute the proceeds of such sales or such properties to the Partners, after giving effect to the distributions and all allocations under Section 4.1 for the current and prior Fiscal Years, in accordance with and in the order of priority listed in Section 4.3.

(c) Except as expressly provided herein, the liquidator shall comply with any applicable requirements of the Act and all other applicable laws pertaining to the winding up of the affairs of the Partnership and the final distribution of its assets.

(d) Notwithstanding any provision in this Agreement to the contrary, no Partner shall be obligated to restore a deficit balance in its Capital Account at any time.

ARTICLE IX

ASSIGNMENTS OF INTERESTS

Section 9.1. Assignment by Partners.

(a) No Limited Partner’s interest in the Partnership, or any rights therein shall be transferred by any Limited Partner except in accordance with the terms of this Article IX. As used in this Article IX, the term “transfer” (whether used as a noun or a verb) shall refer to any sale, transfer, or other disposition whether by sale, by gift, or otherwise, and whether voluntary, involuntary, or by operation of law, to any Person, including but not limited to an involuntary transfer in Bankruptcy, a transfer in connection with or as a result of a divorce of a Limited Partner, any pledge, assignment, hypothecation or grant of a security interest, or any transfer by devise or inheritance; provided, however, that this Article IX shall not restrict the voluntary transfer by any Limited Partner to a member of the Limited Partner’s immediate family or to an Affiliate of a Limited Partner (a “Permitted Transfer”). Any attempt by a Limited Partner to transfer its interest without complying with the terms of this Article IX shall be void ab initio.

(b) The General Partner’s interest in the Partnership, or any rights therein shall not be sold, assigned, mortgaged, pledged, subjected to a security interest or otherwise encumbered, in whole or in part, without the prior written consent of the Required Percentage of the Class A Limited Partners. Any attempt by the General Partner to assign its interest without the required consent shall be void ab initio.

(c) Except as provided in Section 9.4, any permitted transfer of Partnership Interests and the admission of new Partners shall not constitute an amendment to this Agreement.

Section 9.2. Partnership Right of First Refusal.

(a) Written Notice. If any Limited Partner (a “Transferring Limited Partner”) proposes to transfer any of its Partnership Interests, other than pursuant to a Permitted Transfer, the Transferring Limited Partner shall give the Partnership written notice of the interest in the Partnership to be transferred (the “Offered Interests”), the price, terms, closing date and conditions of the proposed transfer (the “Transfer Notice”).

(b) Partnership Option. On receipt of the Transfer Notice, the Partnership will have the exclusive right and option, exercisable at any time during a period of thirty (30) days from the date of the Transfer Notice, to purchase any of the Offered Interests upon the same terms and conditions as contained in the Transfer Notice. If the consideration for the Offered Interests from the third Person is for consideration other than money, the Partnership may substitute, for the other consideration, an amount of money equivalent to the lesser of (i) the fair market value of the other consideration, or (ii) the fair market value of the Offered Interests, in each case as determined by the General Partner. The good faith determination of fair market value by the General Partner shall be conclusive and binding, absent manifest error. If the Partnership decides to exercise its option to purchase any of the Offered Interests, it will give written notice to that effect to the Transferring Limited Partner. The right of the Partnership to exercise its option to purchase is subject to the laws of the State of Delaware governing the rights of a limited partnership to purchase its own limited partnership interests.

(c) Failure to Give Written Notice. If the Transferring Limited Partner does not give the Partnership written notice of the Partnership Interests to be transferred, then the Partnership may exercise the right and option described in Section 9.2(b) at any time.

(d) Sale to Third Person. If the Partnership does not elect to purchase all of the Offered Interests, the Partnership will give written notice to that effect to the Transferring Limited Partner, and the Transferring Limited Partner will have the right to transfer the Offered Interests not elected to be purchased by the Partnership to the third Person, pursuant to the terms of the offer, and the third Person will execute and become a party to this Agreement and will hold the Partnership Interests subject to all the terms and conditions of this Agreement. If the third Person fails to purchase the Offered Interests within thirty (30) days of the date of the notice from the Partnership that all of the Offered Interests will not be purchased by the Partnership, any subsequent offers for the Partnership Interests must be made pursuant to the terms of this Agreement.

(e) Consent of Trustee in Bankruptcy. If the transfer occurs as a result of Bankruptcy, then at the Partnership’s election the purchase of the Offered Interests by the Partnership shall not be consummated without the prior written consent of the trustee in Bankruptcy, if any, or without other applicable approval of the Bankruptcy court.

(f) Closing; Payment of Purchase Price. If the Partnership elects to purchase the Offered Interests pursuant to this Section 9.2 , then:

(i) Closing. The closing of the purchase will be held at the offices of the Partnership on the thirtieth (30th) day following the Partnership’s election to acquire the

Offered Interests under the terms of this Agreement, or any other date and place as the parties may agree. If the thirtieth (30th) day is not a Business Day, the closing will be held on the next following Business Day.

(ii) Payment. The Partnership shall pay the purchase price by a cashier’s check drawn on a national bank or by wire transfer of immediately available funds. The full amount of the purchase price must be paid at the closing, unless the terms of sale under this Section 9.2 permit another method of payment, or unless the parties to the sale agree otherwise. At the closing, the Transferring Limited Partner or other Person or Persons holding the Partnership Interests to be transferred will duly execute and deliver the certificates evidencing the Partnership Interests to the Partnership, in proper form for transfer, free and clear of all liens, adverse claims and encumbrances, except as contained in this Agreement.

Section 9.3. Drag Along Rights. If at any time after the General Partner, with the consent of the Class A Limited Partners in accordance with Section 5.2, shall approve (i) a proposal from a Person for the transfer, directly or indirectly, to such Person of more than fifty percent (50%) of the Percentage Interests of all Limited Partners, (ii) the merger or consolidation of the Partnership with or into another Person or (iii) the sale by the Partnership of all or substantially all of its assets to a Person, in each of the above cases for a specified price payable in cash or otherwise and on specified terms and conditions (a “Sale Proposal”), then the General Partner may deliver a notice (a “Required Sale Notice”) with respect to such Sale Proposal to each Limited Partner stating that the Required Percentage of the Class A Limited Partners have approved the Sale Proposal, and that the Partnership proposes to effect the Sale Proposal, and providing the identity of the Persons involved in such Sale Proposal and the terms thereof. Each Limited Partner, upon receipt of a Required Sale Notice, shall be obligated to sell its Partnership Interests and participate in the transaction (a “Required Sale”) contemplated by the Sale Proposal and otherwise to take all necessary action to cause the Partnership and the Limited Partners to consummate such Required Sale. Any such Required Sale Notice may be rescinded by the General Partner, with the written consent of the Required Percentage of the Class A Limited Partners, by delivering written notice thereof to all of the Limited Partners prior to the consummation of the sale.

Section 9.4. Admission of Partners.

(a) Unless an assignee of an interest in the Partnership becomes a substituted Partner in accordance with the provisions set forth herein, such assignee shall not be entitled to any of the rights granted to a Partner hereunder, other than the right to receive allocations of income, gains, losses, deductions, credits and similar items and distributions to which the assignor would otherwise be entitled, to the extent such items are assigned.

(b) An assignee of an interest in the Partnership shall become a substituted Partner entitled to all of the rights of a Partner if, and only if, (i) the assignor gives the assignee such right, (ii) the General Partner consents in writing to such substitution, the granting or denying of which shall be in the General Partner’s sole discretion, (iii) the assignee executes and delivers such documents as the General Partner may deem necessary or desirable to effect such substitution and to confirm the agreement of the assignee to be bound by all of the terms and

provisions of this Agreement, and (iv) unless waived by the General Partner in its sole discretion, the assignee reimburses the Partnership for any costs incurred by the Partnership in connection with such assignment and substitution. Upon the satisfaction of such requirements, such assignee shall be admitted as of such date as shall be provided for in any document evidencing such assignment as a substituted Partner of the Partnership.

(c) The Partnership and the General Partner shall be entitled to treat the record owner of any Partnership interest as the absolute owner thereof in all respects and shall incur no liability for distributions of cash or other property made in good faith to such owner until such time as a written assignment of such interest that complies with the terms of this Agreement has been received by the General Partner.

Section 9.5. Removal of the General Partner. The Required Percentage of the Class A Limited Partners may remove the General Partner and select a new General Partner to operate and carry on the business and affairs of the Partnership. Any such successor General Partner will be named in, and its appointment as such will be effective as of a date specified in, a notice to the General Partner from the Limited Partners exercising the right to remove the General Partner and select the successor General Partner. The removal of the General Partner shall be effective only if and when the following conditions have been satisfied:

(a) A successor General Partner shall have been selected and shall have agreed to accept the responsibilities of a General Partner and shall have made arrangements to release the removed General Partner from personal liability on all permitted Partnership indebtedness; and if the Partnership creditors will not consent to such release, the new General Partner shall indemnify, in a manner reasonably satisfactory to the removed General Partner, the removed General Partner for such liability.

(b) This Agreement and the Certificate of Limited Partnership of the Partnership shall have been duly amended to name the new General Partner. To the extent required by the laws of any jurisdiction to which the Partnership or this Agreement is subject, the Partners hereby unanimously consent to the admission of such successor General Partner and hereby appoint such successor General Partner as the agent and attorney in fact for each Partner (including without limitation the retiring General Partner) for the purpose of signing, swearing to and filing an amendment to the Certificate of Limited Partnership of the Partnership and all other necessary or appropriate documents in connection with the substitution of such successor General Partner.

(c) Either (i) a favorable ruling shall have been received by the Partnership from the Internal Revenue Service to the effect that neither the grant nor the exercise of the powers described in this Section 9.5 will materially adversely affect the tax status of the Partnership or any of the Partners, or (ii) counsel for the Limited Partners shall have delivered to the Limited Partners an opinion to the same effect.

Section 9.6. Right of General Partner Upon Removal. In the event the General Partner is removed in accordance with Section 9.5, the incoming General Partner shall have the right to purchase from the removed General Partner the general partner interest in the Partnership at a price equal to the appraised value thereof. Such appraised value shall be determined by a qualified independent appraiser who is mutually agreed upon by both the removed General

Partner and the incoming General Partner within thirty (30) days after the selection of the incoming General Partner. If the removed General Partner and the incoming General Partner cannot mutually agree upon a single independent appraiser within such period, they shall each select their own independent appraiser and those two appraisers shall select a third independent appraiser. The cost of such appraisal shall be borne equally by the Partnership and by the removed General Partner. The incoming General Partner’s option to acquire such interest must be exercised by notice in writing to the removed General Partner not more than twenty (20) days after the selection of the incoming General Partner and the purchase price for such interest shall be paid in cash not more than thirty (30) days after receipt by the parties of the report of the appraiser setting forth the appraised value. In the event the incoming General Partner does not elect to purchase the general partner interest of the removed General Partner pursuant to the provisions of this Section 9.6, the remaining interest of the General Partner, if any, shall be converted to Class A Partnership Interest and the removed General Partner shall continue as a Class A Limited Partner in accordance with the Act.

ALLOCATIONS AND TAX PROCEDURES

ARTICLE B-I
DEFINITIONS

B.1. Definitions. Capitalized words and phrases used in this Exhibit B have the meaning ascribed to them in the Agreement except as otherwise provided below:

B.1.1 “Adjusted Capital Account Deficit” means, with respect to any Partner, the deficit balance, if any, in such Partner’s Capital Account as of the end of the relevant Fiscal Year, after giving effect to the following adjustments:

(a) Credit to such Capital Account any amounts which such Partner is obligated to restore pursuant to any provision of this Agreement or is deemed to be obligated to restore pursuant to the penultimate sentences of Treas. Reg. §§ 1.704-2(g)(1) and 1.704-2(i)(5); and

(b) Debit to such Capital Account the items described in Treas. Reg. §§ 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5), and 1.704-1(b)(2)(ii)(d)(6).

The foregoing definition of Adjusted Capital Account Deficit is intended to comply with the provisions of Treas. Reg. § 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith.

B.1.2 “Capital Account” means, with respect to any Partner, the Capital Account maintained for such Partner in accordance with the following provisions:

(a) To each Partner’s Capital Account there shall be credited (A) such Partner’s Capital Contributions, (B) such Partner’s distributive share of Profits and any items in the nature of income or gain which are specially allocated pursuant to Sections B.2.3 or B.2.4 hereof, and (C) the amount of any Partnership liabilities assumed by such Partner or which are secured by any property distributed to such Partner. The principal amount of a promissory note which is not readily tradable on an established securities market and which is contributed to the Partnership by the maker of the note (or a Partner related to the maker of the note within the meaning of Treas. Reg. § 1.704-1(b)(2)(ii)(c)) shall not be included in the Capital Account of any Partner until the Partnership makes a taxable disposition of the note or until (and to the extent) principal payments are made on the note, all in accordance with Treas. Reg. § 1.704-1(b)(2)(iv)(d)(2).

(b) To each Partner’s Capital Account there shall be debited (A) the amount of cash and the Gross Asset Value of any property distributed to such Partner pursuant to any provision of this Agreement, (B) such Partner’s distributive share of Losses and any items in the nature of expenses or losses

which are specially allocated pursuant to Sections B.2.3 or B.2.4 hereof, and (C) the amount of any liabilities of such Partner assumed by the Partnership or which are secured by any property contributed by such Partner to the Partnership.

(c) In the event all or a portion of a Partner’s interest in the Partnership is transferred in accordance with the terms of this Agreement, the transferee shall succeed to the Capital Account of the transferor to the extent it relates to the transferred interest; and

(d) In determining the amount of any liability for purposes of subparagraphs (a) and (b) above, there shall be taken into account Code Section 752(c) and any other applicable provisions of the Code and Treasury Regulations.

The foregoing provisions and the other provisions of this Agreement relating to the maintenance of Capital Accounts are intended to comply with Treas. Reg. § 1.704-1(b), and shall be interpreted and applied in a manner consistent therewith. In the event the General Partner shall determine that it is prudent to modify the manner in which the Capital Accounts, or any debits or credits thereto (including, without limitation, debits or credits relating to liabilities which are secured by contributed or distributed property or which are assumed by the Partnership or the Partners), are computed in order to comply with Treas. Reg. § 1.704-1(b), the General Partner may make such modification, provided that it is not likely to have a material effect on the amounts distributable to any Partner pursuant to this Agreement upon the dissolution of the Partnership. The General Partner also shall (i) make any adjustments that are necessary or appropriate to maintain equality between the Capital Accounts of the Partners and the amount of Partnership capital reflected on the Partnership’s balance sheet, as computed for book purposes, in accordance with Treas. Reg. § 1.704-1(b)(2)(iv)(g), and (ii) make any appropriate modifications in the event unanticipated events might otherwise cause this Agreement not to comply with Treas. Reg. § 1.704-1(b), provided that, to the extent that any such adjustment is inconsistent with other provisions of this Agreement and would have a material adverse effect on any Partner, such adjustment shall require the consent of such Partner.

B.1.3 “Code” means the Internal Revenue Code of 1986, as amended and in effect from time to time, as interpreted by the applicable regulations thereunder.

B.1.4 “Partnership Minimum Gain” has the meaning set forth in Treas. Reg. §§ 1.704-2(b)(2) and 1.704-2(d) for such term.

B.1.5 “Depreciation” means, for each Fiscal Year, an amount equal to the depreciation, amortization, or other cost recovery deduction allowable for federal income tax purposes with respect to an asset for such Fiscal Year, except that if the Gross Asset Value of an asset differs from its adjusted basis for federal income tax purposes at the beginning of such Fiscal Year, Depreciation shall be an amount which bears the same ratio to such beginning Gross Asset Value as the federal income tax depreciation, amortization, or other cost recovery deduction for such Fiscal Year bears to such

B-2

beginning adjusted tax basis; provided, however, that if the federal income tax depreciation, amortization, or other cost recovery deduction for such Fiscal Year is zero, Depreciation shall be determined with reference to such beginning Gross Asset Value using any reasonable method selected by the General Partner.

B.1.6 “Gross Asset Value” means, with respect to any asset, the asset’s adjusted basis for federal income tax purposes, except as follows:

(a) The initial Gross Asset Value of any asset contributed by a Partner to the Partnership shall be the gross fair market value of such asset, as determined by the contributing Partner and the General Partner.

(b) The Gross Asset Values of all Partnership assets shall be adjusted to equal their respective gross fair market values (taking Code Section 7701(g) into account), as determined by the General Partner, as of the following times: (A) the acquisition of an additional interest in the Partnership by any new or existing Partner in exchange for more than a de minimis capital contribution; (B) the distribution by the Partnership to a Partner of more than a de minimis amount of property as consideration for an interest in the Partnership; and (C) the liquidation of the Partnership within the meaning of Treas. Reg. § 1.704-1(b)(2)(ii)(g); provided, however, that adjustments pursuant to clauses (A) and (B) above shall be made only if the General Partner reasonably determines that such adjustments are necessary or appropriate to reflect the relative economic interests of the Partners in the Partnership.

(c) The Gross Asset Value of any Partnership asset distributed to any Partner shall be adjusted to equal the gross fair market value (taking into account Code Section 7701(g) into account) of such asset on the date of distribution as determined by the General Partner.

(d) The Gross Asset Values of Partnership assets shall be increased (or decreased) to reflect any adjustments to the adjusted basis of such assets pursuant to Code Section 734(b) or Code Section 743(b), but only to the extent that such adjustments are taken into account in determining Capital Accounts pursuant to Treas. Reg. § 1.704-1(b)(2)(iv)(m), subparagraph (f) of the definition of “Profits” and “Losses” and Section B.2.3(g) hereof; provided, however, that Gross Asset Values shall not be adjusted pursuant to this subparagraph (d) to the extent the General Partner determines that an adjustment pursuant to subparagraph (b) hereof is necessary or appropriate in connection with a transaction that would otherwise result in an adjustment pursuant to this subparagraph (d). If the Gross Asset Value of an asset has been determined or adjusted pursuant to subparagraphs (a), (b) or (d) hereof, such Gross Asset Value shall thereafter be adjusted by the Depreciation and Simulated Depletion (as applicable) taken into account with respect to such asset.

The amount of Nonrecourse Deductions for an Fiscal Year shall generally equal the net increase, if any, in the amount of Partnership Minimum Gain for that Fiscal Year, reduced (but not below zero) by the aggregate distributions during the year of proceeds of Nonrecourse Liabilities that are allocable to an increase in Partnership Minimum Gain, with such other modifications as provided in Treas. Reg. § 1.704-2(c).

B.1.11 “Nonrecourse Liability” has the meaning set forth in Treas. Reg. § 1.704-2(b)(3).

B.1.12 “Partially Adjusted Capital Account” shall mean with respect to any Partner and any Fiscal Year, the Capital Account of such Partner at the beginning of such Fiscal Year, adjusted as set forth in the definition of Capital Account for all contributions and distributions during such year (including any actual or anticipated Tax Distributions for such year) and all special allocations pursuant to Section B.2.3 and Section B.2.4 with respect to such Fiscal Year, but before giving effect to any allocations of Profits and Losses for such Fiscal Year pursuant to Section B.2.1 and Section B.2.2, plus the Partner’s share of Minimum Gain determined under Treas. Reg. § 1.704-2(g) and plus the Partner’s share of “partner nonrecourse debt minimum gain,” as defined and determined in Treas. Reg. §§ 1.704-(2)(i)(2) and 1.704-2(i)(4), all computed immediately prior to the hypothetical sale described in the definition for Target Capital Account.

B.1.13 “Profits” and “Losses” means, for each Fiscal Year, an amount equal to the Partnership’s taxable income or loss for such Fiscal Year, determined in accordance with Code Section 703(a) (for this purpose, all items of income, gain, loss, or deduction required to be stated separately pursuant to Code Section 703(a)(1) shall be included in taxable income or loss), with the following adjustments (without duplication):

(a) Any income of the Partnership that is exempt from federal income tax and not otherwise taken into account in computing Profits or Losses pursuant to this definition of “Profits” and “Losses” shall be added to such taxable income or loss.

B-4

Reg. § 1.704-1(b)(2)(iv)(i), and not otherwise taken into account in computing Profits or Losses pursuant to this definition of “Profits” and “Losses” shall be subtracted from such taxable income or loss.

(c) In the event the Gross Asset Value of any Property is adjusted pursuant to subparagraphs (b) or (c) of the definition of “Gross Asset Value,” hereof, the amount of such adjustment shall be treated as an item of gain (if the adjustment increases the Gross Asset Value of the asset) or an item of loss (if the adjustment decreases the Gross Asset Value of the asset) from the disposition of such asset and shall be taken into account for purposes of computing Profits or Losses.

Reg. § 1.704-1(b)(2)(iv)(m)(4) to be taken into account in determining Capital Accounts as a result of a distribution other than in complete liquidation of a Partner’s interest in the Partnership, the amount of such adjustment 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) from the disposition of such asset and shall be taken into account for purposes of computing Profits or Losses.

(g) Any items which are specially allocated pursuant to Sections B.2.3 or B.2.4 hereof shall not be taken into account in computing Profits or Losses. The amounts of the items of Partnership income, gain, loss, or deduction available to be specially allocated pursuant to Sections B.2.3 or B.2.4 hereof shall be determined by applying rules analogous to those set forth in subparagraphs (a) through (f) above.

ALLOCATIONS OF PROFITS AND LOSSES

B.2.1 Profits. After giving effect to the special allocations set forth in Sections B.2.3 and B.2.4 hereof, Profits for any Fiscal Year shall be allocated in the following order and priority:

Profits for any Fiscal Year shall be allocated among the Partners so as to reduce, proportionately, the differences between their respective Target Capital Accounts and Partially Adjusted Capital Accounts for such Fiscal Year. No portion of the Profits for any Fiscal Year shall be allocated to a Partner whose Partially Adjusted Capital Account is greater than or equal to its Target Capital Account for such Fiscal Year.

B.2.2 Losses. After giving effect to the special allocations set forth in Sections B.2.3 and B.2.4 hereof, Losses for any Fiscal Year shall be allocated as set forth in Section B.2.2(a) below, subject to the limitation in Section B.2.2(b) below:

(a) Losses for any Fiscal Year shall be allocated among the Partners so as to reduce, proportionately, the differences between their respective Partially Adjusted Capital Accounts and Target Capital Accounts for such Fiscal Year. No portion of the Losses shall be allocated to a Partner whose Target Capital Account is greater than or equal to its Partially Adjusted Capital Account for such Fiscal Year.

(b) The Losses allocated pursuant to Section B.2.2(a) hereof shall not exceed the maximum amount of Losses that can be so allocated without causing any Limited Partner to have an Adjusted Capital Account Deficit at the end of any Fiscal Year. In the

B-6

event some but not all of the Limited Partners would have Adjusted Capital Account Deficits as a consequence of an allocation of Losses pursuant to Section B.2.2(a), the limitation set forth in this Section B.2.2(b) shall be applied on a Limited Partner by Limited Partner basis so as to allocate the maximum permissible Losses to each Limited Partner under Treas. Reg. § 1.704-1(b)(2)(ii)(d), with any excess losses allocated to the General Partner.

B.2.3 Special Allocations. The following special allocations shall be made in the following order and priority:

(a) Minimum Gain Chargeback. Except as otherwise provided in Treas. Reg. § 1.704-2(f), notwithstanding any other provision of this Agreement, if there is a net decrease in Partnership Minimum Gain during any Fiscal Year, each Partner shall be specially allocated items of Partnership income and gain for such Fiscal Year (and, if necessary, subsequent Fiscal Years) in an amount equal to such Partner’s share of the net decrease in Partnership Minimum Gain, determined in accordance with Treas. Reg. § 1.704-2 (g). Allocations pursuant to the previous sentence shall be made in proportion to the respective amounts required to be allocated to each Partner pursuant thereto. The items to be so allocated shall be determined in accordance with Treas. Reg. §§ 1.704-2(f)(6) and 1.704-2(j)(2). This Section B.2.3(a) is intended to comply with the minimum gain chargeback requirement in Treas. Reg. § 1.704-2(f) and shall be interpreted consistently therewith.

(b) Partner Nonrecourse Debt Minimum Gain Chargeback. Except as otherwise provided in Treas. Reg. § 1.704-2(i)(4), notwithstanding any other provision of this Agreement, if there is a net decrease in Partner Nonrecourse Debt Minimum Gain attributable to a Partner Nonrecourse Debt during any Fiscal Year, each Partner who has a share of the Partner Nonrecourse Debt Minimum Gain attributable to such Partner Nonrecourse Debt, determined in accordance with Treas. Reg. § 1.704-2(i)(5), shall be specially allocated items of Partnership income and gain for such Fiscal Year (and, if necessary, subsequent Fiscal Years) in an amount equal to such Partner’s share of the net decrease in Partner Nonrecourse Debt Minimum Gain attributable to such Partner Nonrecourse Debt, determined in accordance with Treas. Reg. §§ 1.704-2(i)(4). Allocations pursuant to the previous sentence shall be made in proportion to the respective amounts required to be allocated to each Partner pursuant thereto. The items to be so allocated shall be determined in accordance with Treas. Reg. §§ 1.704-2(i)(4) and 1.704-2(j)(2). This Section B.2.3(b) is intended to comply with the partner nonrecourse debt minimum gain chargeback requirement in Treas. Reg. § 1.704-2(i)(4) and shall be interpreted consistently therewith.

(c) Qualified Income Offset. In the event any Partner unexpectedly receives any adjustments, allocations, or distributions described in Treas. Reg. §§ 1.704-1(b)(2)(ii)(d)(4), 1.704-1(b)(2)(ii)(d)(5) or 1.704-1(b)(2)(ii)(d)(6), items of Partnership income and gain shall be specially allocated to each such Partner in an amount and manner sufficient to eliminate, to the extent required by the Treasury Regulations, the Adjusted Capital Account Deficit of such Partner as quickly as possible, provided that an

B-7

allocation pursuant to this Section B.2.3(c) shall be made only if and to the extent that such Partner would have an Adjusted Capital Deficit after all other allocations provided for in this Agreement have been tentatively made as if this Section B.2.3(c) were not in this Agreement. This Section B.2.3(c) is intended to comply with the qualified income offset requirement in Treas. Reg. § 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith.

(d) Gross Income Allocation. In the event any Partner has a deficit Capital Account at the end of any Fiscal Year which is in excess of the sum of (i) the amount such Partner is obligated to restore pursuant to any provision of this Agreement and (ii) the amount such Partner is deemed to be obligated to restore pursuant to the penultimate sentences of Treas. Reg. §§ 1.704-2(g)(1) and 1.704-2(i)(5), 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 B.2.3(d) 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 this Agreement have been made as if Section B.2.3(c) hereof and this Section B.2.3(d) were not in this Agreement.

(e) Nonrecourse Deductions. Nonrecourse Deductions for any Fiscal Year shall be specially allocated to the Partners in accordance with their Percentage Interests.

(f) Partner Nonrecourse Deductions. Partner Nonrecourse Deductions for any Fiscal Year shall be specially allocated to the Partner who bears the economic risk of loss with respect to the Partner Nonrecourse Debt to which such Partner Nonrecourse Deductions are attributable in accordance with Treas. Reg. § 1.704-2(i)(1); provided, however, that if more than one Partner bears the economic risk of loss for such debt, the Partner Nonrecourse Deductions attributable to such Partner Nonrecourse Debt shall be allocated to and among the Partners in the same proportion that they bear the economic risk of loss for such Partner Nonrecourse Debt. This Section B.2.3(f) is intended to comply with the provision of Treas. Reg. § 1.704-2(i) and shall be interpreted consistently therewith.

(g) Section 754 Adjustments. To the extent an adjustment to the adjusted tax basis of any Partnership asset pursuant to Code Section 734(b) or Code Section 743(b) is required, pursuant to Treas. Reg. §§ 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 as the result of a distribution to a Partner in complete liquidation of such Partner’s interest in the Partnership, 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 accordance with their interests in the Partnership in the event Treas. Reg. § 1.704-1(b)(2)(iv)(m)(2) applies, or to the Partner to whom such distribution was made in the event Treas. Reg. § 1.704-1(b)(2)(iv)(m)(4) applies.

(h) Additional Allocations. The following special allocations shall be made:

B-8

	(A)		If the Partnership has Profits for any Fiscal Year (determined before giving effect to this Section B.2.3(h)), any Partner whose Partially Adjusted Capital Account is greater than its Target Capital Account for such Fiscal Year shall be specially allocated items of Partner deduction or loss (included in the calculation of Profits) for such Fiscal Year equal to the difference between its Target Capital Account and its Partially Adjusted Capital Account. In the event the Partnership has insufficient items of deduction and loss for such Fiscal Year to satisfy the previous sentence with respect to all such Partners, the available items of deduction and loss shall be divided among such Partners in proportion to their differences.

	(B)		If the Partnership has Loss for any Fiscal Year (determined prior to giving effect to this Section B.2.3(h)), any Partner whose Target Capital Account is greater than its Partially Adjusted Capital Account for such Fiscal Year shall be specially allocated items of Partnership income or gain (included in the calculation of Loss) for such Fiscal Year equal to the difference between its Partially Adjusted Capital Account and Target Capital Account. In the event the Partnership has insufficient items of income or gain for such Fiscal Year to satisfy the previous sentence with respect to all such Partners, the available items of income or gain shall be divided among such Partners in proportion to such differences.

	(C)		The availability of items of income, gain, loss or deduction to be specially allocated pursuant to this Section B.2.3(h) shall be determined after giving full effect to all of the preceding provisions of Section B.2.3.

(i)

Simulated Depletion, Simulated Loss and Simulated Gain. Simulated Depletion and Simulated Loss shall be allocated under Treas. Reg. §1.704-1(b)(2)(iv)(k) with any election required under such section made by the General Partner. Any Simulated Gain shall be included in the computation of Profits and Loss.

B.2.4 Curative Allocations. The allocations set forth in Sections B.2.2(b) and C.2.3(a) through (g) (the “Regulatory Allocations”) are intended to comply with certain requirements of the Treasury Regulations. It is the intent of the Partners that, to the extent possible, all Regulatory Allocations shall be offset either with other Regulatory Allocations or with special allocations of other items of Partnership income, gain, loss or deduction pursuant to this Section B.2.4. Therefore, notwithstanding any other provision of this Agreement (other than the Regulatory Allocations), the General Partner shall make such offsetting allocations of Partnership income, gain, loss, or deduction in whatever manner it determine appropriate so that, after such offsetting allocations are made, each Partner’s Capital Account balance is, to the

B-9

extent possible, equal to the Capital Account balance such Partner would have had if the Regulatory Allocations were not part of this Agreement.

B.2.5 Intent of Allocations. The parties intend that the allocation provisions of this Exhibit B shall produce final Capital Account balances of the Partners that will permit liquidating distributions in accordance with Section 8.2(b) of the Agreement. To the extent that the allocations required in this Exhibit B would fail to produce such final Capital Account balances, (i) such allocation provisions shall be amended by the General Partner if and to the extent necessary to produce such result and (ii) items of Partnership income, gain, loss, or deduction for prior open taxable years shall be reallocated by the General Partner among the Partners to the extent it is not possible to achieve such result with allocations of Partnership income, gain, loss, or deduction for the current taxable year and future taxable years.

B.2.6 Other Allocation Rules.

(a) Profits, Losses or any other items allocable to any period shall be determined on a daily, monthly or other basis, as determined by the General Partner using any permissible method under Code Section 706 and the Treasury Regulations thereunder.

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

(c) Solely for purposes of determining a Partner’s proportionate share of the “excess nonrecourse liabilities” of the Partnership within the meaning of Treas. Reg. § 1.752-3(a)(3), the Partners’ interests in Partnership profits shall be allocated in accordance with their Percentage Interests.

(d) To the extent permitted by Treas. Reg. § 1.704-2(h)(3), the General Partner shall endeavor to treat distributions as having been made from the proceeds of a Nonrecourse Liability or a Partner Nonrecourse Debt only to the extent that such distributions would cause or increase an Adjusted Capital Account Deficit for any Partner.

(e) For purpose of Section 613A(c)(7)(D) of the Code, the adjusted tax basis of an oil and gas property shall be allocated to the Partners in their Percentage Interests, as of the acquisition of the property or as otherwise reasonably determined by the General Partner consistent with Section 613A(c)(7)(D) and Treas. Reg. § 1.704-1(b)(2)(iv)(k).

B.2.7 Tax Allocations; Code Section 704(c).

(a) In accordance with Code Section 704(c) and the Treasury 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

B-10

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 its initial Gross Asset Value (computed in accordance with subparagraph (a) of the definition of “Gross Asset Value”). The Partnership shall utilize the traditional method with curative allocations as described in Treas. Reg. § 1.704-3(c) with respect to each item of contributed property.

(b) In the event the Gross Asset Value of any Partnership asset is adjusted pursuant to subparagraph (b) 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 Treasury Regulations thereunder.

(c) Subject to Section B.2.7(a), any elections or other decisions relating to such allocations shall be made by the General Partner. Allocations pursuant to this Section B.2.7 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 Partner’s Capital Account or share of Profits, Losses, other items, or distributions pursuant to any provision of this Agreement.

(d) Except as otherwise provided in this Agreement, all items of Partnership income, gain, loss, deduction, and any other allocations not otherwise provided for shall be divided among the Partners in the same proportions as they share Profits or Losses, as the case may be, for the Fiscal Year. For purposes of determining the nature (as ordinary or capital) of any Partnership gain allocated among the Partners for Federal income tax purposes pursuant to this Agreement, the portion of such gain required to be recognized as ordinary income pursuant to Code Sections 1245 and/or 1250 shall be deemed to be allocated among the Partners in accordance with Treas. Reg. § 1.1245-1(e)(2) and 1.1250-1(f).

B.2.8 Reliance on Advice of Accountants and Attorneys. The General Partner will have no liability to the Partners or the Partnership if the General Partner relies upon the written opinion of tax counsel or accountants retained by the Partnership with respect to all matters (including disputes) relating to computations and determinations required to be made under this Exhibit B or other related provisions of this Agreement.

ARTICLE B-III
OTHER TAX MATTERS

B.3.1 Tax Returns. The General Partner shall prepare and timely file all federal, state, and local tax returns required to be filed by the Partnership in accordance with Section 5.9 of the Agreement.

B.3.2 Tax Elections. The Partnership shall make the following elections for tax purposes on the appropriate returns:

B-11

(a) to the extent permitted by law, to adopt the calendar year as the Partnership’s taxable year;

(b) to the extent permitted by law, to adopt the accrual method of accounting and to keep the Partnership’s books and records on the accrual method;

(c) if a distribution of the Partnership’s property as described in Code Section 734 occurs or upon a transfer of an interest in the Partnership as described in Code Section 743 occurs, on request by notice from any Partner, to elect, pursuant to Code Section 754, to adjust the basis of Partnership’s properties;

(d) to elect to amortize the organizational expenses of the Partnership ratably over a period of 60 months as permitted by Code Section 709(b); and

(e) any other election the General Partner deems appropriate and in the best interests of the Partners.

The Partnership intends to be classified as a partnership for federal income tax purposes under Treas. Reg. § 301.7701-3. Neither the Partnership nor any Partner may make an election under Treas. Reg. § 301.7701-3(c) to treat the Partnership as an association taxable as a corporation. To the extent Treas. Reg. § 301.7701-3 does not govern the state and local tax classification of the Partnership, the General Partner shall take such action as may be permitted or required under any state and/or local law applicable to the Partnership to cause the Partnership to be taxable as, and in a manner consistent with, a partnership (or the functional equivalent thereof under applicable law) for the state and/or local income tax purposes. In addition, neither the Partnership nor any Partner may make an election for the Partnership to be excluded from the application of the provisions of subchapter K of chapter 1 of subtitle A of the Code or any similar provisions of applicable state law and no provision of this Agreement shall be construed to sanction or approve such an election.

B.3.3 Amounts Withheld. All amounts required to be withheld pursuant to federal, state, local, or foreign tax laws shall be treated as amounts actually distributed to the affected Partners for all purposes under this Agreement. The General Partner is hereby authorized to withhold from distributions, or with respect to allocations, to the Partners and to pay over any federal, state, local, or foreign government any amounts required to be so withheld pursuant to federal, state, or local law.
