subscribed pursuant to this Section 5.6, then in addition to any other rights the Company may have at law or in equity, such Electing Member and any transferee thereof shall not be considered an Eligible Member for any future rights granted under this Section 5.6 unless the Board expressly designates otherwise (which the Board may, in its sole discretion, do on an offer-by-offer basis or not at all) and shall be deemed a Defaulting Member under Section 4.2.

By ** of each calendar year (beginning with calendar year 2012), the Operator shall prepare and submit the following budgets and forecasts for the upcoming year (to the extent such budgets or forecasts are applicable to such upcoming year) to the Board for approval and to the appropriate Members for Requisite Member Approval in accordance with Section 6.12:

Any rejection of the Proposed Budget in whole or in part must be made in good faith, based on commercially reasonable standards and submitted in writing to the Board, the other Members with Requisite Member Approval rights and the Operator and must describe proposed modifications in reasonable detail (a "Budget Rejection Notice"). If a Budget Rejection Notice is not received by such date, then the Proposed Budget will be deemed to be approved in all respects. If a Budget Rejection Notice is received by such date, the Operator, the Board and the Members with Requisite Member Approval rights to approve the Proposed Budget will work together in good faith to promptly resolve the issues identified in a mutually agreeable manner.

ARTICLE 7
ASSIGNABILITY OF MEMBER INTERESTS

Section 7.1 Prohibition on Assignment During Project Period.

Prior to ** (the "Project Period"), no Member may, directly or indirectly, Transfer its Interest or any portion thereof without the prior written consent of the other Members except for Permitted Transfers. For purposes of this Agreement, "Permitted Transfers" shall include the following: (a) a Member may Transfer all or a portion of its Interest to any of its Affiliates, (b) Interests held by any member of the MWE Operating Company Group may be (i) Transferred, in whole or in part, in connection with any sale of all or substantially all of the assets of MWE, or (ii) indirectly Transferred by way of a sale of Control of MWE, or any merger of MWE with or into, or any consolidation of MWE into, any other entity and (c) Interests held by EMG may be transferred to the limited partners of EMG, if and to the extent required by the governance documents of EMG. In the event of a Transfer pursuant to the foregoing clause (c), the EMG Group shall designate a single representative to exercise all of the EMG Group's rights hereunder. If a Member Transfers an Interest during the Project Period in accordance with this Section 7.1, such Transfer shall entitle the assignee to become a Substitute Member and to exercise or receive the rights, powers or benefits of a Member if the assigning Member designates, in a written instrument delivered to the Board and the other Members, its assignee to become a Substitute Member and such assignee executes an instrument reasonably satisfactory to the Board, which shall include an acceptance and agreement by the Substitute Member to abide by all of the terms and conditions of this Agreement. A Member may not Transfer Interests in a Permitted Transfer if such Permitted Transfer has as a purpose the avoidance of the restrictions on

Transfers in this Agreement (it being understood that the purpose of this sentence is to prohibit the Transfer of Interests to a transferee in a Permitted Transfer followed by a change in the relationship between the transferor and the transferee (or a change of Control of such transferor or transferee) after the Permitted Transfer with the result and effect that the transferor has indirectly Transferred Interests to a transferee in a Transfer which would not have been directly permitted as a Permitted Transfer under this Section 7.1 had such change in such relationship occurred prior to such Transfer).

Section 7.2 Transfers After the Project Period.

After the Project Period, a Member may Transfer its Interest, or any portion thereof, without the consent of any other Member or the Board, provided, that such Member complies with the requirements of this Section 7.2 in all instances except in connection with Permitted Transfers:

(a) In the event that a Member (the "Transferring Member") desires to Transfer, directly or indirectly, all or any portion of its Interest (the "ROFO Interest") and such Transfer is not a Permitted Transfer, then the Transferring Member shall give written notice thereof to the other Members (the "Remaining Members"). For a period of 30 days thereafter, all or a portion of the Remaining Members shall have the right, but not the obligation, to submit a written offer to purchase the ROFO Interest (with each offering Remaining Member to purchase its pro rata portion of the ROFO Interest as is determined in accordance with the respective Percentage Interests of the Remaining Members, or such other portion as the Remaining Members may mutually agree upon) (the "ROFO Offer"), on such terms and conditions as the offering Remaining Members may determine and which terms and conditions shall be described in the ROFO Offer. Upon receipt of the ROFO Offer, the Transferring Member may elect in its sole discretion to accept or reject the ROFO Offer.

(i) In the event that the Transferring Member elects to accept the ROFO Offer, then the Transferring Member shall be bound to Transfer to the offering Remaining Members, and the offering Remaining Members shall be bound to purchase from the Transferring Member, the ROFO Interest on the terms and conditions set forth in the ROFO Offer (with such modifications as may be mutually agreed upon by the offering Remaining Members and the Transferring Member), and the closing of such Transfer of the ROFO Interest shall occur within 30 days of the Transferring Member's acceptance of the ROFO Offer or on such other date as may be set forth in the ROFO Offer (subject to extension to the extent necessary to pursue any required regulatory approvals, including to allow for the expiration or termination of all waiting periods under the Xxxx-Xxxxx-Xxxxxx Antitrust Improvements Act of 1976).

(ii) In the event that the Transferring Member rejects the ROFO Offer, then for a 60-day period after the date on which the Transferring Member rejects the ROFO Offer (the "Solicitation Period"), the Transferring Member may solicit an offer to purchase the ROFO Interest from one or more third parties as the Transferring Member may determine in its discretion. If the Transferring Member receives a third party offer (a "Third Party Offer") to purchase the ROFO Interest within the Solicitation Period, and the consideration payable for the ROFO Interest pursuant to such Third Party Offer exceeds the consideration payable for the ROFO Interest pursuant the ROFO Offer (such Third Party Offer is referred to as a "Qualifying Third Party Offer"), the Transferring Member may elect to Transfer the ROFO Interest to such third party in accordance with the Qualifying Third Party Offer within 30 days after the end of the Solicitation Period, subject to the Transferring Member's compliance with the provisions of Sections 7.2(a)(iii) and 7.2(b). Any noncash consideration set forth in the ROFO Offer or a Third Party Offer shall be valued at its fair market value, as agreed by the Transferring Member and the offering Remaining Members, and failing such agreement, as determined by an independent third party appraiser selected by the Transferring Member and reasonably acceptable to the offering Remaining Members (the costs for which third party appraiser shall be shared equally by the Transferring Member, on the one hand, and the offering Remaining Members, on the other hand).

The Transferring Member may not Transfer the ROFO Interest to any third party pursuant to a Third Party Offer that is not a Qualifying Third Party Offer without the offering Remaining Members' prior written consent, which may be withheld in their sole discretion. Such transferee shall become a Substitute Member if the Transferring Member designates, in a written instrument delivered to the Board and the other Members, the transferee to become a Substitute Member and such transferee executes an instrument reasonably satisfactory to the Board, which shall include an acceptance and agreement by the Substitute Member to abide by all of the terms and conditions of this Agreement. If such closing does not occur within the required 30-day period, then the ROFO Interest in question shall once again become subject to the restrictions of this Section 7.2, and the Transferring Member shall no longer be permitted to Transfer such ROFO Interest without again fully complying with the provisions of this Section 7.2

(iii) Prior to the Transferring Member electing to Transfer the ROFO Interest to a third party in accordance with a Qualifying Third Party Offer pursuant to Section 7.2(a)(ii), the Transferring Member must comply with this Section 7.2(a)(iii). Prior to accepting a Qualifying Third Party Offer pursuant to Section 7.2(a)(ii), the Transferring Member shall give written notice thereof to the other Members. For a period of 15 days thereafter, the Remaining Members shall have the right, but not the obligation, to purchase the ROFO Interest (with each offering Remaining Member to purchase its pro rata portion of the ROFO Interest as is determined in accordance with the respective Percentage Interests of the Remaining Members, or such other portion as the Remaining Members may mutually agree upon) at ** the price proposed in the Qualifying Third Party Offer, and otherwise on the same terms and conditions set forth in the Qualifying Third Party Offer. In the event that one or more of the Remaining Members exercise such ** purchase right, the closing of the Transfer of the ROFO Interest shall occur within 30 days of the Remaining Members' purchase election or on such other date as the participating parties mutually agree.

(b) Except for any Transfer to another Member and except for Permitted Transfers, each Class B Member hereby agrees, whether in one transaction or in a series of related transactions, not to Transfer for value, all or any portion of its Interest, directly or indirectly, without first complying with Section 7.2(a) and then permitting each of the Remaining Members (the "Tag-Along Members") to participate as sellers in such transaction (the "Tag-Along Rights"), such that each Tag-Along Member shall be entitled to sell, on the same terms as the Class B Member proposing to sell its Interest (the "Class B Seller"), a portion of such Tag-Along Member's Interest, determined by multiplying the Interest that the purchaser is willing to acquire by the Percentage Interest of each such Tag-Along Member desiring to participate.

(i) Before accomplishing or entering into a binding contract for any Transfer for value of any Interest that would be covered by the Tag-Along Rights, the Class B Seller agrees to give each Tag-Along Member written notice (the "Tag-Along Notice") of any such proposed sale (the "Sale Proposal"). The Tag-Along Notice shall state that such Tag-Along Member shall be entitled to exercise its Tag-Along Rights. Each Tag-Along Member shall notify the Class B Seller in writing within 10 days after receipt of the Tag-Along Notice as to whether or not such Tag-Along Member wishes to exercise Tag-Along Rights and participate in the proposed Transfer (the "Tag-Along Notice Period"). Failure by any Tag-Along Member to respond within such period shall be deemed to be a declination of such Tag-Along Member's Tag-Along Rights with respect to such proposed transfer. The Class B Seller shall use its commercially reasonable efforts to obtain the agreement of the prospective transferee(s) to the participation of the Tag-Along Members in any contemplated Sale Proposal and to the inclusion of the Tag-Along Members' Interests in such transaction, and no Class B Seller shall transfer any portion of the Interest to any prospective transferee if such prospective transferee(s) declines to allow the participation of the Tag-Along Members or the inclusion of their Interests as contemplated herein. Each Tag-Along Member that elects to

participate pursuant to this paragraph shall pay its pro rata share (based on the Interests to be Transferred) of the expenses incurred by the Class B Seller in connection with such Sale Proposal and shall be obligated to join on a pro rata basis (based on the Interests to be Transferred) in any indemnification or other obligations that Class B Seller agrees to provide in connection with such Sale Proposal (other than any such obligations that relate specifically to a particular Member such as indemnification with respect to representations and warranties given by a Member regarding such Member's title to and ownership of its Interest); provided, that no Tag-Along Member shall be obligated in connection with such Sale Proposal to agree to indemnify or hold harmless the transferee with respect to an amount in excess of the net cash proceeds paid to such Tag-Along Member in connection with such Sale Proposal. If the Tag-Along Members decline, or are deemed to decline, their Tag-Along Rights for any proposed transfer, the Class B Seller may sell its offered Interest; provided, however, that (A) such Sale Proposal is consummated within 90 days after the end of the Tag-Along Notice Period and (B) the terms of the actual transaction involve exactly the same consideration and other terms and conditions set forth in the Tag-Along Notice. Any transferee pursuant to the Sale Proposal shall become a Substitute Member if the Class B Seller designates, in a written instrument delivered to the Board and the other Members, the transferee to become a Substitute Member and such transferee executes an instrument reasonably satisfactory to the Board, which shall include an acceptance and agreement by the Substitute Member to abide by all of the terms and conditions of this Agreement. Failure to close the Sale Proposal within the required 90-day period shall again subject the offered Interest to the Tag-Along Rights set forth in this Section 7.2(b), whereupon the Class B Seller shall be required to give each Tag-Along Member a new written notice with respect to the proposed transfer, and each Tag-Along Member shall again have the right to exercise Tag-Along Rights in respect of such proposed transfer.

(ii) If a Class B Seller wishes to solicit Sale Proposals from third parties involving a Company Sale, it shall first notify the other Members of its desire to solicit a Company Sale ("Solicitation Notice"). The other Members shall notify the Class B Seller in writing within 10 days after receipt of the Solicitation Notice as to whether or not such Members wish to participate in a Company Sale and shall specify a minimum price ("Minimum Price") at which such Members are willing to sell their Interest thereunder ("Solicitation Response"). If the Class B Seller obtains Solicitation Responses from all of the Members indicating each Member's desire to enter into a Company Sale and a Minimum Price with respect to each Member, then the Class B Seller may solicit offers for a Company Sale. If the Class B Seller obtains an offer within 90 days of its receipt of the Solicitation Responses for a Company Sale in excess of each of the Minimum Prices set forth in the Solicitation Responses ("Company Sale Offer"), it may cause a Company Sale pursuant to the terms and provisions set forth in Section 7.2(b)(iii). If the Class B Seller does not obtain an offer for a Company Sale in excess of the minimum prices set forth in the Solicitation Responses within 90 days of its receipt of the Solicitation Responses, then the Class B Seller may not pursue a Company Sale. For the avoidance of doubt, this Section 7.2(b)(ii) shall only apply to a Company Sale to be solicited by a Class B Member. Any sale of the Interest of a Class B Seller that is not a Company Sale shall remain subject to the provisions of Section 7.2(b)(i) above.

(iii) Within five days after receipt of a Company Sale Offer that the Class B Seller desires to accept, the Board shall notify each Member, in writing, of such Company Sale Offer ("Company Sale Notice"). The Company Sale Notice shall identify the transferee, the proposed consideration and all other material terms and conditions of the Company Sale, including the form of the proposed agreement, if any, and provide a copy of all relevant documents and agreements related to such Company Sale. Each Member agrees that upon receipt of a Company Sale Notice it will (i) take such action as may reasonably be required, including voting its Interest and/or including its Interest in any such Company Sale, (ii) cause its designated Managers to take such action required, to approve and cause such Company Sale to promptly be consummated, (iii) provide for the execution of such agreements and such instruments and other actions reasonably necessary to

provide, to the extent necessary, customary several (and not joint) representations, warranties, indemnities, and escrow/holdback arrangements relating to such Company Sale, in each case only to the extent that each other holder of Interests is similarly obligated; provided that, no Affiliated Member Group shall be obligated in respect of any indemnity obligations with respect to the customary representations, warranties and indemnities made on a several (and not joint) basis and referred to in the immediately preceding clause in such Company Sale for an aggregate amount in excess of the total consideration payable to such Affiliated Member Group in such Company Sale. The Member proposing such Company Sale shall have the right in connection with any such transaction (or in connection with the investigation or consideration of any such potential transaction) to require the Company to cooperate fully with potential acquirors in such prospective Company Sale by taking all customary and other actions reasonably requested by the Member proposing the Company Sale or such potential acquirors, including making the Company's properties, books and records, and other assets reasonably available for inspection by such potential acquirors, establishing a data room including materials customarily made available to potential acquirors in connection with such processes and making its employees reasonably available for presentations, interviews and other diligence activities, in each case subject to reasonable and customary confidentiality provisions. The Company and each Member shall provide assistance with respect to these actions as reasonably requested by the Member proposing the Company Sale. In addition, once a Company Sale is properly initiated under this Section 7.2, the Board shall be entitled to take all steps reasonably necessary to carry out an auction of the Company, including selecting an investment bank, providing Confidential Information (pursuant to confidentiality agreements), selecting the winning bidder and negotiating the requisite documentation; provided, however, that the rights granted the Board in this sentence shall not permit the Board to veto such a properly initiated Company Sale.

(c) The consideration or value allocated to the Members under this Section 7.2 shall be allocated among the Transferring Member and other Members (whether Tag-Along Members or otherwise) in accordance with their respective rights to distributions from the Company as if the Company had been liquidated pursuant to Section 13.4 and the Company had sold all of its Property for an appraised value using the implied valuation of such Property that may be derived from the sales process described in Section 7.2, and, except for such consideration, no Member will receive any payments of any nature whatsoever from the transferee in connection with or arising from such sale transaction.

Section 7.3 Recognition of Assignment by Company or Other Members.

No Transfer of an Interest that is in violation of this Article 7 shall be valid or effective, and neither the Company nor the Board nor any Member shall recognize the same for any purpose of this Agreement, including the purpose of making distributions of Available Cash pursuant to this Agreement with respect to such Interest or part thereof. Neither the Company nor the Board shall incur any liability as a result of refusing to make any such distributions to the assignee of any such invalid assignment.

Section 7.4 Effective Date of Assignment.

Any valid Transfer of a Member's Interest, or part thereof, pursuant to the provisions of this Article 7 shall be effective as of the later of (i) the date of Transfer set forth on the written instrument of Transfer, (ii) the date on which the Company has received the written instrument of Transfer and such other documents as may be required by the Company pursuant to this Agreement and such Transfer has been recorded on the books of the Company, and (iii) the date on which the requirements of this Article 7 have been satisfied. The Company shall, from the effective date of such Transfer, thereafter pay all further distributions on account of the Interest (or part thereof) so assigned to the assignee of such Interest, or part thereof. As between any Member and its assignee, Profits and Losses for the Fiscal Year of the Company in which such assignment occurs shall be apportioned for federal income tax purposes in accordance with any convention permitted under Section 706(d) of the Code and selected by the Board.

Section 7.5 Limitations on Transfer.

No Transfer of an Interest may be effectuated unless in the opinion of counsel satisfactory to the Board, the Transfer (a) would comply with the Securities Act and applicable securities laws of any other jurisdiction; (b) would not cause the Company to be terminated for purposes of Code Section 708; or (c) would not violate any other applicable laws, provided, that the provisions of this Section 7.5 may be waived by the Board.

Section 7.6 Transferee Not a Substitute Member.

In the event that a transferee is not designated, or does not become, a Substitute Member pursuant to this Article 7, then such transferee shall not be entitled to exercise or receive any of the rights, powers or benefits of a Member other than the right to receive distributions to which the assigning Member would be entitled.

ARTICLE 8
DISTRIBUTIONS TO MEMBERS

Section 8.1 Available Cash.

Available Cash shall be determined by the Board on a quarterly basis within 45 days after the end of each calendar quarter.

The Board is authorized to withhold from distributions, or with respect to allocations, to the Members and to pay over to any federal, foreign, state or local government any amounts required to be so withheld pursuant to the Code or any provision of any other federal, foreign, state or local law or treaty and shall allocate such amounts to those Members with respect to which such amounts were withheld.

The "Assumed Tax Liability" of each Member means an amount equal to (i) the cumulative amount of federal income taxes (including any applicable estimated taxes), determined taking into account the character of income and loss allocated to such Member as it affects the applicable tax rate, that the Board estimates would be due from such Member as of such Tax Distribution Date, assuming such Member were an individual that earned solely the items of income, gain, deduction, loss and/or credit allocated to such Member pursuant to Section 9.4 (after reflecting any adjustments thereto by reason of Code Sections 732(d), 734, or 743), reduced by (ii) all previous distributions made to such Member pursuant to this Article 8.

To the extent Losses allocated to a Member would cause such Member to have an Adjusted Capital Account Deficit at the end of any Fiscal Year, the Losses will be reallocated to other Members. If any Member receives an allocation of Losses otherwise allocable to another Member in accordance with this Section 9.1(a), such Member shall be allocated Profits in subsequent Fiscal Years necessary to reverse the effect of such allocation of Losses. Such allocation of Profits (if any) shall be made before any other Profit allocations under this Section 9.1(a).

If more than one Member bears the Economic Risk of Loss with respect to a Member Nonrecourse Debt, Member Nonrecourse Deductions attributable thereto shall be allocated between or among such Members in accordance with the ratios in which they share such Economic Risk of Loss. This Section 9.2(b) is intended to comply with the provisions of Treasury Regulation Section 1.704-2(i) and shall be interpreted consistently therewith.

(c) Company Minimum Gain Chargeback. Notwithstanding any other provision of this Agreement, if there is a net decrease in Minimum Gain during any taxable year, each Member shall be allocated items of Company income and gain for such year (and, if necessary, subsequent taxable years) in the manner and amounts provided in Treasury Regulation Sections 1.704-2(f)(6), (g)(2) and (j)(2)(i). For purposes of this Section 9.2, each Member's Capital Account shall be determined, and the allocation of income or gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Article 9 with respect to such taxable year. This Section 9.2(c) is intended to comply with the partner minimum gain chargeback requirement in Treasury Regulation Section 1.704-2(f) and shall be interpreted consistently therewith.

(d) Member Nonrecourse Debt Minimum Gain Chargeback. Notwithstanding the other provisions of this Agreement (other than Section 9.2(c) above), if there is a net decrease in Member Nonrecourse Debt Minimum Gain during any taxable year, any Member with a share of Member Nonrecourse Debt Minimum Gain at the beginning of such taxable year shall be allocated items of Company income and gain for such year (and, if necessary, subsequent taxable years) in the manner and amounts provided in Treasury Regulation Section 1.704-2(i)(4) and (j)(2)(ii). For purposes of this Section 9.2, each Member's Adjusted Capital Account balance shall be determined, and the allocation of income and gain required hereunder shall be effected, prior to the application of any other allocations pursuant to this Article 9, other than Section 9.2(c) above, with respect to such taxable year. This Section 9.2(d) is intended to comply with the partner nonrecourse debt minimum gain chargeback requirement in Treasury Regulation Section 1.704-2(i)(4) and shall be interpreted consistently therewith.

(e) Qualified Income Offset. Except as provided in Sections 9.2(c) and 9.2(d) above, in the event any Member unexpectedly receives an adjustment, allocation or distribution described in Treasury Regulation Sections 1.704-1(b)(2)(ii)(d)(4), (5) or (6), items of Company income and gain shall be allocated to such Member in an amount and manner sufficient to eliminate, to the extent required by such Treasury Regulation, the deficit balance, if any, in its Adjusted Capital Account created by such adjustment, allocation or distribution as quickly as possible unless such deficit balance is otherwise eliminated pursuant to Sections 9.2(c) or 9.2(d). This Section 9.2(e) is intended to constitute a qualified income offset described in Treasury Regulation Section 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith.

(f) Gross Income Allocation. In the event any Member has a deficit balance in its Adjusted Capital Account at the end of any taxable year, such Member shall be allocated items of Company gross income and gain in the amount of such excess as quickly as possible; provided, however, that an allocation pursuant to this Section 9.2(f) shall be made only if and to the extent that such Member would have a deficit balance in its Adjusted Capital Account after all other allocations provided in this Section 9.2 (other than Section 9.2(e)) have been tentatively made as if Section 9.2(e) and this Section 9.2(f) were not in this Agreement.

Section 9.3 Curative Allocations.

The allocations set forth in Section 9.2 (the "Regulatory Allocations") are intended to comply with certain requirements of the Treasury Regulations. It is the intent of the Members that, to the extent possible, all Regulatory Allocations shall be offset either with other Regulatory Allocations or with

special allocations of other items of Company income, gain, loss or deduction pursuant to this Section 9.3. Therefore, notwithstanding any other provision of this Article 9 (other than the Regulatory Allocations), but subject to the Code and the Treasury Regulations, the Board shall make such offsetting special allocations of Company income, gain, loss or deduction in whatever manner it determines appropriate so that, after such offsetting allocations are made, each Member's Capital Account balance is, to the extent possible, equal to the Capital Account balance such Member would have had if the Regulatory Allocations were not part of this Agreement. In exercising its discretion under this Section 9.3, the Board shall take into account future Regulatory Allocations that, although not yet made, are likely to offset other Regulatory Allocations previously made.

Section 9.4 Income Tax Allocations.

(a) Except as provided in this Section 9.4, each item of income, gain, loss and deduction of the Company for federal income tax purposes shall be allocated among the Members in the same manner as such items are allocated for book purposes under Sections 9.1, 9.2, 9.3 and 13.4(b).

(b) In accordance with Code Section 704(c) and the applicable Treasury Regulations thereunder, income, gain, loss and deduction with respect to any property contributed to the Company shall, solely for tax purposes, be allocated among the Members so as to take account of any variation between the adjusted basis of such property to the Company for federal income tax purposes and its Gross Asset Value at the time of its contribution to the Company. If the Gross Asset Value of any Company property is adjusted in accordance with clause (c) or (d) of the definition of Gross Asset Value, then subsequent allocations of income, gain, loss and deduction shall take into account any variation between the adjusted basis of such property for federal income tax purposes and its Gross Asset Value as provided in Code Section 704(c) and the related Treasury Regulations. For purposes of such allocations, the Company shall elect the remedial allocation method described in Treasury Regulation Section 1.704-3(d).

(c) All items of income, gain, loss, deduction and credit allocated to the Members in accordance with the provisions hereof and basis allocations recognized by the Company for federal income tax purposes shall be determined without regard to any election under Section 754 of the Code which may be made by the Company.

(d) If any deductions for depreciation or cost recovery are recaptured as ordinary income upon the Transfer of Company properties, the ordinary income character of the gain from such Transfer shall be allocated among the Members in the same ratio as the deductions giving rise to such ordinary character were allocated.

Section 9.5 Allocation and Other Rules.

(a) In the event Members are admitted to the Company pursuant to this Agreement on different dates, the Profits (or Losses) allocated to the Members for each Fiscal Year during which Members are so admitted shall be allocated among the Members in proportion to their Percentage Interests during such Fiscal Year in accordance with Section 706 of the Code, using any convention permitted by law and selected by the Board that takes into account the varying interests of the Members during such Fiscal Year.

(b) For purposes of determining the Profits, Losses or any other items allocable to any period, Profits, Losses and any such other items shall be determined on a daily, monthly or other basis, as determined by the Board using any method that is permissible under Section 706 of the Code and the Treasury Regulations thereunder.

(c) The Members are aware of the income tax consequences of the allocations made by this Article 9 and hereby agree to be bound by the provisions of this Article 9 in reporting their shares of Company income and loss for income tax purposes.

(d) Allocations made by the Board under Section 9.2 in reliance upon the advice of the Company's accountants shall be deemed to be made pursuant to any fiduciary obligation to the Company and the Members.

(e) If any Member makes a loan to the Company, or the Company makes a loan to any Member, and interest in excess of the amount actually payable is imputed under Code Sections 7872, 483, or 1271 through 1288 or corresponding provisions of subsequent federal income tax law, then any item of income or expense attributable to any such imputed interest shall be allocated solely to the Member who made or received the loan and shall be credited or charged to its Capital Account, as appropriate.

Section 13.7 Distributions In-Kind.

If any assets of the Company shall be distributed in kind, such assets shall be distributed to the Member(s) entitled thereto as tenants-in-common in the same proportions as such Member(s) would have been entitled to cash distributions if (i) such assets had been sold for cash by the Company at the fair market value of such property (taking the Gross Asset Value definition herein and Code Section 7701(g) into account) on the date of distribution; (ii) any unrealized income, gain, loss and deduction inherent in such property (that has not been reflected in the Capital Accounts previously) that would be realized by the Company from such sale were allocated among the Member(s) as Profits or Losses in accordance with this Agreement; and (iii) the cash proceeds were distributed to the Member(s) in accordance with this Article 13. The Capital Accounts of the Member(s) shall be increased by the amount of any unrealized income or gain inherent in such property or decreased by the amount of any loss or deduction inherent in such property that would be allocable to them, and shall be reduced by the fair market value of the assets distributed to them under the preceding sentence.
