(iii) If a Class A Member's Capital Commitment as set forth on Exhibit A is less than $1,000,000, the entire amount of such Capital Commitment shall be contributed to the Company by the Class A Member on execution of this Agreement. For purposes of Section 1.3 of this Agreement (relating to the calculation of Adjusted Percentage Interest) and 1.12 of this Agreement (relating to Basic Threshold Return) only, the Capital Contributions of Class A Members described in the first sentence of this Section 3.1(c)(iii) shall be deemed to be 1/5 of the total Capital Contributions of such Class A Members, plus the same portion of such Class A Members' Capital Commitment, as such amount may increase from time to time, that such Class A Member would have been obligated to contribute to the Company pursuant to a Stock Purchase Agreement Capital Call given by the Zhone Board to the Company and the Major Class A Members, if such Class A Member had instead been subject to the same Capital Contribution funding procedure of Major Class A Members as set forth in Section 3.1(c)(ii). The Capital Contributions of Class A Members described in the first sentence of this Section 3.1(c)(iii) which are not treated as Capital Contributions for purposes of Sections 1.3 and 1.12, shall be referred to as a "Deposit." The Deposit shall be deposited by the Manager in an interest bearing savings or money market account. The Deposit shall be withdrawn by the Manager to the extent necessary to satisfy the pro rata obligations of the Class A Members described in the first sentence of this Section 3.1(c)(iii) pursuant to a Stock Purchase Agreement Capital Call by the Zhone Board to the Company, and contributed by the Manager on behalf of such Class A Members to Zhone.

Section 3.3 Delinquency. ----------- (a) If a Major Class A Member fails to make a payment to Zhone under Section 3.1(c) by the "Delinquency Date" (which date shall be twelve (12) business days after notice of the Stock Purchase Agreement Capital Call is deemed given under the Stock Purchase Agreement), such payment shall thereafter be a "Delinquent Payment" and the Major Class A Member shall thereafter be "Delinquent." (b) If a Major Class A Member is Delinquent: (i) The Zhone Board shall give all Affiliated Class A Members notice (the "Affiliated Class A Members Notice") of that fact within five (5) days of the Delinquency Date; (ii) Each Major Class A Member grants each Affiliated Class A Member the option (the "CYA Option") to acquire the same percentage (the "CYA Percentage") of the Delinquent Percent as of the Delinquency Date of the Delinquent Major Class A Member's Adjusted Percentage Interest, Series A Preferred Units, share of the Adjusted Unreturned Class A Member's Capital Contribution and Basic Threshold Return (collectively the "Delinquent's Interest") as the amount of such Affiliated Class A Member's capital contribution commitment to an Affiliated LLC bears to the aggregate capital contribution commitments of all Affiliated Class A Members to all Affiliated LLCs; (iii) Within three (3) business days of the Affiliated Class A Members Notice, each Affiliated Class A Member shall notify the remaining Affiliated Class A Members and the Zhone Board whether the Affiliated Class A Member will or will not exercise its CYA Option. Failure by an Affiliated Class A Member to give that notification within such three (3) business day period will be deemed a notice of non-exercise of the Affiliated Class A Member's CYA Option. Each Affiliated Class A Member giving notice pursuant to this Section 3.3(b)(iii) that it will exercise its CYA Option is referred to as a "CYA Person"; (iv) If an Affiliated Class A Member does not exercise its CYA Option, the CYA Persons shall have the right within fifteen (15) business days after the Affiliated Class A Member Notice to exercise the CYA Option of such Affiliated Class A Member pro rata based on their respective capital contribution commitments to an Affiliated LLC or as they may otherwise agree; (v) Exercise of the CYA Option of a CYA Person shall be by tender of the CYA Person within the fifteen (15) business day period described in Section 3.3(b)(iv) of the CYA Person's percentage, as determined pursuant to Sections 3.3(b)(ii) and/or (iv), (the "CYA Share") of the Delinquent Payment to Zhone, together with an agreement, in a form reasonably acceptable to the Zhone Board and a Class B Majority, to assume such CYA Person's CYA Share of the entire unpaid Capital Contribution Commitment of the Delinquent Major Class A Member (net of the Delinquent Payment); 12 (vi) If the aggregate of the tenders described in Section 3.3(b)(v) equals the Delinquent Payment and the aggregate of the assumptions described in Section 3.3(b)(v) equals the entire unpaid Capital Contribution Commitment of the Delinquent Class A Member (net of the Delinquent Payment), then: (A) Each CYA Person exercising its CYA Option shall be admitted to the Company as a Special Class A Member in place of the Delinquent Major Class A Member with respect to the product of: (I) the percentage of which such CYA Person's CYA Share is of all CYA Person's Shares, and (II) the Delinquent's Interest; (B) the Capital Contribution Commitment of each CYA Person as a Special Class A Limited Partner shall be the aggregate amount of its tender, assumption and CYA Share of the Delinquent Percent of the Delinquent Major Class A Member's share of the Adjusted Unreturned Class A Members' Capital Contribution as of the Delinquency Date; and (C) the Delinquent Major Class A Member's share of the Delinquent's Interest shall be reduced to reflect the share of that Interest transferred to all CYA Persons under Section 3.3(b)(vi)(A); (D) At the direction of one or more of such CYA Persons, the Manager shall cause the Company to commence action against the Delinquent Major Class A Member pursuant to Section 10.13 to collect the entire unpaid Capital Contribution Commitment of the Delinquent Major Class A Member as of the Delinquency Date plus interest at the rate charged from time to time by the Bank of America for prime corporate borrowers plus two percent (but not in excess of the maximum rate allowed by applicable law), plus the expenses of collection, including attorney's fees; and (E) All of the decision, direction and approval rights which the Delinquent Major Class A Member was entitled to exercise under this Agreement immediately before the Delinquency Date shall be exercised by CYA Persons acquiring a majority of the Series A Units transferred to the CYA Persons from the Delinquent Major Class A Member pursuant to Section 3.3(b)(vi)(A); (vii) Not withstanding the prior provisions of this Section 3.3(b), unless the aggregate of the tenders described in Section 3.3(b)(v) equals the Delinquent Payment and the aggregate of the assumptions described in Section 3.3(b)(v) equals the entire unpaid Capital Contribution Commitment of the Major Delinquent Class A Member (net of the Delinquent Payment), Section 3.3(c) shall apply and the prior provisions of this Section 3.3(b) shall not apply. (c) If pursuant to Section 3.3(b)(vii), this Section 3.3(c) applies then a Class B Majority may in its sole discretion, elect any of the following alternatives by notice to the Delinquent Major Class A Member and to Zhone within 120 days after the Delinquency Date: 13 (i) To direct the Manager to cause the Company to commence an action against the Delinquent Major Class A Member pursuant to Section 10.13 to collect the entire unpaid Capital Contribution Commitment of the Delinquent Major Class A Member as of the Delinquency Date plus interest at the rate charged from time to time by the Bank of America for prime corporate borrowers plus two percent (but not in excess of the maximum rate allowed by applicable law), plus the expenses of collection, including attorneys' fees; or (ii) To cause one or more designees of a Class B Majority to assume the entire unpaid balance of the Capital Contribution Commitment of the Delinquent Major Class A Member (in which event the Delinquent Major Class A Member shall not be permitted to make any further Capital Contributions to the Company) on such terms and conditions, as determined by a Class B Majority and the Zhone Board, including but limited to, amending this Agreement to admit such designee as a Special Class A Member and in any such amendment diluting and subordinating the priorities of the interest of the Delinquent Major Class A Member in Company Income and distributions (as reduced pursuant to Section 3.3(b)) to the interests of any or all of such designee and the Class B Members. (d) The alternatives in Sections 3.3(a), (b) and (c) are in addition to and not in limitation of any other right or remedy of Zhone, the Company, the Affiliated Class A Members and the Class B Members. Furthermore, if a Major Class A Member is Delinquent, thereafter notwithstanding any other provision of this Agreement: (i) "Adjusted Post Cover Date Shortfall" under this Agreement shall be calculated as though the Delinquent Major Class A Member had made no Capital Contributions to the Company and such Delinquent Major Class A Member shall not share in any distributions or Income allocations of or related to an Adjusted Post Cover Date Shortfall; (ii) "Basic Threshold Return" under this Agreement shall be calculated as though the Delinquent Major Class A Member had made no Capital Contributions to the Company and such Delinquent Major Class A Member shall not share in any distributions or Income allocations of or related to a Basic Threshold Return; (iii) "Post Cover Date Basic Threshold Shortfall" under this Agreement shall be calculated as though the Delinquent Major Class A Member had made no Capital Contributions to the Company and such Delinquent Major Class A Member shall not share in any distributions or Income allocations of or related to a Post Cover Date Basic Threshold Shortfall; (iv) "Post Cover Date Capital Return Shortfall" under this Agreement shall be calculated as though the Delinquent Major Class A Member had made no Capital Contributions to the Company and such Delinquent Major Class A Member shall not share in any distributions or Income allocations of or related to a Post Cover Date Capital Return Shortfall; and (v) If Section 3.3(c) applies: For all purposes of calculating the Adjusted Percentage Interest of the Members: 14 (A) the Capital Contributions of the Delinquent Major Class A Member shall be deemed to be 25% of the amount of the actual Capital Contributions of the Delinquent Major Class A Member as of the Delinquency Date, (B) a member of Series A Preferred Units equal to: (I) the Special Delinquent Percent multiplied by (II) the Major Class A Member's Series A Preferred Units, shall no longer be outstanding Series A Units, and (C) the Company shall transfer to Zhone the Special Delinquent Percent of the Preferred Stock for $100. Section 3.4 Appropriateness of Remedies. To the extent any of the --------------------------- remedies available against a Delinquent Class A Member under Section 3.3 results or is deemed to result in the recovery of damages by the Company and/or the Class B Members, the Delinquent Class A Member agrees that the damage recovery is an appropriate amount of liquidated damages for the delinquency. The Members acknowledge that determining the actual damages now or at the time the Class A Member becomes Delinquent would be impossible, and the remedies in this Section represent a reasonable liquidated damage allowance for the failure by the Delinquent Class A Member to make a Capital Contribution when required. Section 3.5 No Interest; Return of Contributions. Except as set forth in ------------------------------------ Section 5.6 below, no Member shall be entitled to receive any interest on the Member's Capital Contributions. Except as otherwise provided in this Agreement, no Member shall have the right to receive the return of any Capital Contribution or withdraw from the Company, except upon the dissolution of the Company. Notwithstanding the foregoing, any remaining Deposit (plus accrued interest) shall be refunded to the Class A Members described in the first sentence of Section 3.1(c)(iii), in proportion to their respective Capital Contributions, upon the termination of the Stock Purchase Agreement Capital Call provisions described in Section 2.2(e) of the Stock Purchase Agreement. Section 3.6 Capital Account. --------------- (a) The Company shall establish and maintain a separate account (the "Capital Account") for each Member. The initial balance of the Capital Account for each Member shall be such Member's initial Capital Contribution to the Company. The Capital Account of each Member shall be increased by (i) the dollar amount of any additional cash contributions made by such Member, (ii) the fair market value of any property (other than cash) contributed to the Company by such Member (net of liabilities to which such property is subject), and (iii) allocations to such Member of its share of Income. The Capital Account of each Member shall be decreased by (i) the dollar amount of any cash distributions made to such Member, (ii) the fair market value of any property distributed to such Member (net any liabilities to which such property is subject), and (iii) allocations to such Member of its share of Losses. (b) Notwithstanding any other provision of this Agreement to the contrary, the foregoing provisions of paragraph (a) regarding the maintenance of Capital Accounts shall be construed so as to comply with the provisions of the Treasury Regulations promulgated pursuant to section 704 of the Code. The Manager is hereby authorized with the approval of a Majority 15 Interest to modify the foregoing provisions to the minimum extent necessary to comply with such Treasury Regulations. Section 3.7 Loans. Subject to the limitations set forth in Section 4.6 ----- and with the prior approval of a Majority Interest, a Member may lend money to and transact other business with the Company; provided that the terms of such loan are no less favorable to the Company than those that could reasonably be obtained by the Company in an arms-length transaction negotiated with an unrelated third party. Any permitted loan to the Company made by a Member shall not entitle the lending Member to any greater share of Company distributions or subject the lending Member to any greater proportionate allocation of Company Income or Losses. The amount of any such loan or advance shall be a debt owed by the Company to the lending Member on the terms agreed to by the Managers. Subject to other applicable law, such Member has the same rights and obligations with respect thereto as a Person who is not a Member. SECTION IV MANAGEMENT AND CONTROL OF THE COMPANY Section 4.1 Election of the Manager. The Company shall have one (1) ----------------------- Manager who shall be the Person identified in Section 1.40.

The resignation of the Manager shall take effect upon receipt of that notice or at such later time as shall be specified in the notice. Unless otherwise specified in the notice, the acceptance of the resignation shall not be necessary to make it effective. The resignation of a Manager who is also a Member shall not affect the Manager's rights as a Member and shall not constitute a withdrawal of a Member. (b) The Manager may be removed: (i) at any time, with or without cause, by notice from a Class A Majority; (ii) by notice from a Class B Majority for failure of the Manager to take any action which a Class B Majority alone is entitled to direct the Manager to take under this Agreement, within two (2) days of such direction. In the event of any such failure, a Class B Majority shall, whether or not it gives such notice, have the authority to cause the Company to take the directed action. (c) Any vacancy occurring for any reason in the position of Manager shall be filled by the affirmative vote or written consent of a Majority Interest. Section 4.2 Management of the Company by the Manager. ---------------------------------------- (a) Subject to Sections 3.3, 4.1, 4.2(b) and (c), the business and affairs of the Company shall be managed exclusively by the Manager, as directed by a Majority Interest, and 16 the Manager shall have the power pursuant to such direction to do any and all acts necessary or convenient to or for the furtherance of the purposes of the Company described herein. (b) (i) All decisions/voting/ control rights which by the terms of the Preferred Stock, the provisions of any organizational document of Zhone, any agreement to which Zhone is a party or any applicable law, may be exercised by the holder of the Preferred Stock, including decisions as to conversion and all determinations as to the disposition of the Preferred Stock, will (other than on the occurrence of an event described in Section 8.1(e)) be exercised on behalf of the Company by a Class A Majority directly or at a Class A Majority's direction, by the Manager; provided that such Class A Majority may not cause the Company, without the consent of the Class A Member of Zhone Investors I L.L.C. (as defined in the Operating Agreement of Zhone Investors I L.L.C.) and the Class A Member of Zhone Investors II L.L.C. (as delivered in the Operating Agreement of Zhone Investors II L.L.C.), to dispose of: (A) a greater percentage of Preferred Stock as of any date (on a cumulative basis from the date of this Agreement) than (B) the percentage of "Preferred Stock" ( as defined in the respective Operating Agreements of Zhone Investors I L.L.C. and Zhone Investors II L.L.C.) which as of such date has been collectively disposed of by Zhone Investors I L.L.C. and Zhone Investors II L.L.C.. (iii) All decisions/voting/control rights which by the terms of the Common Stock, the provisions of any organizational document of Zhone, any agreement to which Zhone is a party or any applicable law, may be exercised by the holder of the Common Stock and all determinations as to the disposition of the Common Stock (other than on the occurrence of an event described in Section 8.1(e)) will be exercised on behalf of the Company by a Class B Majority directly, or at the direction of a Class B Majority, by the Manager. Such Class B Majority may not, however, without the consent of the Class A Member of Zhone Investors I L.L.C. and Zhone Investors II L.L.C. cause the Company to dispose of a greater percentage of Common Stock as of any date (on a cumulative basis from the date of this Agreement) than the percentage of the "Preferred Stock" (as defined in the Operating Agreements of Zhone Investors I L.L.C. and Zhone Investors II L.L.C.) as of such date on a cumulative basis from the date of this Agreement which has been disposed of by both of Zhone Investors I L.L.C. and Zhone Investors II L.L.C. as of such date. In no event, however, may such percentage of Common Stock exceed the percentage which the aggregate number of Series B Common Units which have then vested under one or more of the Zhone Securities Repurchase Agreements between the Company and the Class B Members is of all Series B Common Units issued pursuant to all such Agreements. (iv) The Manager shall exercise the voting rights of the Securities held by the Company in accordance with the directions of the Class A Majority or a Class B Majority, pursuant to Section 4.2(b)(i) or Section 4.2(b)(ii) as applicable. (c) A Class A Majority shall have the sole right to determine whether the Company shall exercise any of the registration rights to which the Company is entitled to exercise with respect to the Preferred Stock under the "Rights Agreement" in the form of 17 Exhibit E and to make all decisions on behalf of the Company relating to registration rights, including, but not limited to the amount of Preferred Stock to be included in any registration pursuant to the Rights Agreement. A Class A Majority may act directly on behalf of the Company with respect to such exercise or direct the Manager with respect to such exercise. Section 4.3 Performance of Duties; Liability of Manager. The Manager ------------------------------------------- shall not be liable to the Company or to any Member for any loss or damage sustained by the Company or any Member and attributable to any act or failure to act by the Manager, unless the Manager has failed to comply with the good faith standard of this Section 4.3 or the loss or damage shall have been the result of fraud, deceit, reckless or intentional misconduct, or a knowing violation of law by the Manager. The Manager shall perform the Manager's managerial duties in good faith, in a manner the Manager reasonably believes to be in the best interests of the Company, and with such care, including reasonable inquiry, as an ordinarily prudent person in a like position would use under similar circumstances. A Manager who so performs the duties of Manager shall not have any liability by reason of being or having been a Manager of the Company. Section 4.4 Devotion of Time. The Manager, in the capacity as Manager, ---------------- shall devote whatever time, and effort as a Class A Majority reasonably deems appropriate for the operation of the Company.

(b) Business Opportunities. The Members, the Manager and any ---------------------- Affiliates of the Members or the Manager shall not be obligated to present any investment opportunity or prospective advantage to the Company even if such opportunity or advantage is of a character that relates to the Company's business and, if presented to the Company, could be taken by the Company.

Unless otherwise determined by -------------------------- Majority Interest, the Manager, in the Manager's capacity as Manager, shall not be entitled to a salary and remuneration for services rendered to the Company. Any salary of any Manager who is also a Member shall be treated as a guaranteed payment within the meaning of Section 707(c) of the Code. The Company shall reimburse the Manager and the Manager's Affiliates for the actual cost of materials and third party services used for or by the Company.

(i) Notice of any such meeting shall be given no fewer than five (5) days prior to the date of the meeting. Attendance of a Member at such a meeting, as applicable, shall constitute a waiver of notice of such meeting except where such Member attends such meeting for the express purpose of objecting to the transaction of business because the meeting is not properly called or convened. Neither the business to be transacted nor the purpose of the meeting need be specified in the notice of such meeting. (ii) A Majority Interest shall constitute a quorum for transaction of business at such meeting; provided, however, that if less than a Majority Interest is present at such meeting, a majority of the Persons present may adjourn the meeting at any time without further notice.

(iv) If there is a disposition described in Section 5.2(d) during such fiscal year or part thereof, Income from such disposition shall be allocated to the Class B Members as a group. Notwithstanding the foregoing, to the extent the proceeds of such disposition are distributed to the Class A Members as a group, the Income from the disposition that generated such proceeds shall, to such extent, first instead be allocated to the Class A Members as a group. (b) Losses for each fiscal year or part thereof of the Company shall be allocated among the Members as follows: (i) Losses attributable to costs or expenses of the Company paid with Additional Contributions made pursuant to Section 3.2 shall be allocated to the Class A Members as a group to the extent of its Additional Contributions. (ii) Losses from a disposition of Preferred Stock described in Section 5.2(b) shall be allocated to the Class A Members as a group; (iii) Losses from a disposition of Common Stock described in either Section 5.2(c) or Section 5.2(d) shall be allocated to the Class B Members in proportion to their respective Series B Common Units; (iv) Losses other than as provided in Sections 5.1(b)(i), (ii) and (iii) shall be allocated as follows: (A) first to the Members in proportion to and to the extent of their respective shares of Company Income allocated to them under Section 5.1(a)(i)(D) and not previously taken into account under this Section 5.1(b)(iv)(A); 21 (B) Next to the Members in proportion to and to the extent of their respective positive Capital Account balances remaining after any allocations under Section 5.1(b)(iv)(A); and (C) The balance to the Class A Members as a group and the Class B Members as a group based on the respective Adjusted Percentage Interests of the Class A Members as a group and the Class B Member as a group. (c) Allocations With Respect to Contributed Property. Allocations of ------------------------------------------------ book and tax items with respect to property contributed by any Member shall be made solely for Federal income tax purposes as required by section 704(c) of the Code using the traditional method. Following any revaluation of the Company's assets and the adjustment of any Member's Capital Account pursuant to Regulations section 1.704-1(b)(2)(iv)(f) to reflect such revaluation, the Members' Capital Accounts shall be adjusted for various items as computed for book purposes with respect to such revalued assets as required by Regulations section 1.704-1(b) and the Members' shares of such items as computed for tax purposes with respect to such items shall be determined as required by Regulations section 1.704-1(b). Income or Losses upon the disposition of any property contributed to the Company shall be determined with respect to the book basis of such property instead of its income tax basis. (d) Qualified Income Offset. ----------------------- (i) If any Member unexpectedly receives any adjustment, allocation or distribution described in Regulations section 1.704- 1(b)(2)(ii)(d)(4), (5) or (6), items of Income shall be specially allocated to such Member in an amount and manner sufficient to eliminate any deficit in its Capital Account created by such adjustment, allocation or distribution as soon as practicable. This Section 5.1(d)(i) is intended to constitute a "qualified income offset" within the meaning of Regulations section 1.704- 1(b)(2)(ii)(d)(3). (ii) Any allocations of items of Income pursuant to Section 5.1(d)(i) shall be taken into account in computing subsequent allocations of Income or Losses pursuant to this Article V so that the net amounts of the allocations under this Article V shall, to the maximum extent possible, be equal to the net amounts that would have been allocated pursuant to this Article V if there had been no allocations pursuant to Section 5.1(d)(i). (e) Allocation of Income and Losses and Distributions in Respect of a ----------------------------------------------------------------- Transferred Interest. If any Membership Interest is transferred, or is - -------------------- increased or decreased by reason of the admission of a new Member or otherwise, during any fiscal year, Income or Losses for such fiscal year shall be allocated among the Members by the Tax Matters Partner (as directed by a Majority Interest) using any method permitted under the Code. (f) Adjustment of Allocations. In the event the allocations set forth ------------------------- above are disallowed by the Internal Revenue Service, such allocations shall be deemed to be amended to the minimum extent necessary to conform with section 704 of the Code, while preserving the intent of the foregoing allocations to the maximum possible extent and by making such adjustments to the allocations as are necessary to allow distributions to be made in accordance with Section 5.2. 22 (g) Additional Allocations. Notwithstanding the foregoing, if, upon ---------------------- the final dissolution and termination of the Company and after taking into account all allocations of Income and Losses (and other tax items) under this Section 5.1, the distributions to be made in accordance with the positive Capital Account balances would result in a distribution that would be different from the Distribution Hierarchy provided for under Section 5.2(a) below, then gross items of Income (and other tax items) for the taxable year of the final dissolution and termination (and, to the extent permitted under section 761(c) of the Code, gross items of Income (and other tax items) for the immediately preceding taxable year) shall be allocated to the Members to increase or decrease Capital Account balances, as the case may be, so that the final distribution will occur in under the Distribution Hierarchy provided for under Section 5.2(a) below. (h) Special Rule. Notwithstanding any other provision in Section 5.1, ------------ if Income or Loss arises in a taxable year different from the taxable year in which the associated cash arising from that sale is distributed under Section 5.2, the allocations of such Income and Loss under Section 5.1 shall, to the maximum extent possible, be made as if the associated distribution had occurred in the year the taxable Income or Loss arose, using the principles of Section 5.2 to determine the allocation of such hypothetical distribution. Section 5.2 Distributions by the Company. Subject to applicable law and ---------------------------- any limitations contained elsewhere in this Agreement, all available proceeds from the disposition of the Securities (including dividends, interest and sales proceeds) less reasonable reserves and reasonable costs of the disposition, all as determined by a Majority Interest, shall be distributed to the Members under one of the Distribution Hierarchies (the "Distribution Hierarchies") as follows: (a) Disposition of All Remaining Securities. If the disposition is of --------------------------------------- all of the Securities remaining in the Company, is pursuant to an event described in Section 8.1(e), or is not otherwise governed by any of Sections 5.2(b), (c) or (d), the proceeds shall be distributed in accordance with the following Distribution Hierarchy and priority: (i) First, to the Class A Members as a group to the extent of the Adjusted Unreturned Class A Members' Capital Contribution, (ii) Second, to the Class A Members as a group to the extent of the sum of: (A) The Basic Threshold Return attributable to the portion of the Class A Member's Capital Contribution (determined on a FIFO basis) attributable to all of the Preferred Stock (such portion to be determined consistently with Section 1.3(b)A) disposed of in such disposition; and (B) Any Adjusted Post Cover Date Shortfall as of the date of such disposition (first in payment of any Post Cover Date Basic Threshold Return included therein and then in payment of any Post Cover Date Capital Return Shortfall included therein), (iii) Third, 55% to the Class B Members as a group and 45% to the Class A Members as a group until the Class B Members as a group have received total distributions pursuant to this Section 5.2(a)(iii) equal to the Adjusted Percentage Interest of the 23 Class B Members as a group of all distributions to the Class A Members as a group and the Class B Members as a group pursuant to Sections 5.2(a)(i) and (ii) and this Section 5.2(a)(iii), and (iv) The balance to the Class A Members as a group and the Class B Members as a group based on the respective Adjusted Percentage Interests of the Class A Members as a group and the Class B Members as a group. (b) Disposition of Preferred Stock Not Governed by Section 5.2(a). If ------------------------------------------------------------- the disposition is of any or all of the Preferred Stock (a "Preferred Stock Disposition" or "Disposition"), and the Disposition is not otherwise governed by Section 5.2(a), the proceeds of the disposition shall be distributed in accordance with the following Distribution Hierarchy and priority: (i) First, to the Class A Members as a group to the extent of the Basic Threshold Return remaining unpaid as of the date of the Preferred Stock Disposition, (ii) Second, to the Class A Members as a group to the extent of any of the Class A Members' Capital Contribution remaining unreturned as of the date of the Preferred Stock Disposition, and (iii) The balance to the Class A Members as a group, except if any distributions have been made to the Class A Members as a group under Section 5.2(d), such balance shall first be distributed to the Class B Members as a group until that group has received an aggregate amount under this Section 5.2(b)(iii) equal to the aggregate amount of such distributions to the Class A Members as a group under Section 5.2(d). (c) Disposition of Common Stock Prior to the Cover Date and Not ----------------------------------------------------------- Governed by Section 5.2(a). If the disposition is of Common Stock prior to the - -------------------------- Cover Date and is not otherwise governed by Section 5.2(a), then the proceeds of such disposition shall be distributed to the Class B Members as a group; provided, however, that if such disposition of Common Stock occurs within 90 days of the date of a Preferred Stock Disposition unless all Class A Members are Delinquent, the proceeds of such disposition of Common Stock shall first be distributed to the Class A Members as a group to the extent that any Basic Threshold Return and any of the Class A Members' Capital Contributions as of the date of the Preferred Stock Disposition remains unpaid and unreturned, as the case may be, after the proceeds of the Preferred Stock Disposition have been distributed in accordance with Sections 5.2(b)(i) and (ii). The distribution of proceeds to the Class A Members as a group hereunder shall be made in accordance with the Distribution Hierarchy set forth in Section 5.2(b). (d) Disposition of Common Stock After the Cover Date and Not Governed ----------------------------------------------------------------- by Section 5.2(a). - ----------------- (i) If as a result of a Preferred Stock Disposition governed by Section 5.2(b) and occurring after the Cover Date, the Basic Threshold Return attributable to the portion of the Class A Members' Capital Contribution (determined on a FIFO basis) attributable to the Preferred Stock disposed of in such Disposition exceeds the amount distributed to the Class A Member from such Disposition under Section 5.2(b)(i), there shall be a "Post Cover 24 Date Basic Threshold Shortfall." If the Class A Members' Capital Contributions (determined on a FIFO basis) attributable to the Preferred Stock disposed of in such Disposition exceed the amount distributed to Class A Member from such Disposition under Section 5.2(b)(ii) there shall be a "Post Cover Date Capital Return Shortfall." (ii) In the event there is neither a Post Cover Date Capital Return Shortfall nor a Post Cover Date Basic Threshold Shortfall at the time of a disposition of Common Stock after the Cover Date and such disposition is not otherwise governed by Section 5.2(a), all proceeds of such disposition shall be distributed to the Class B Members as a group. (iii) In the event that there is either, or both, of a Post Cover Date Basic Threshold Shortfall or a Post Cover Date Capital Return Shortfall, the Class B Members as group shall have one year from the date of the Disposition creating any such Shortfall to as, chosen by a Class B Majority, either: (A) Cause the Company to dispose of sufficient Common Stock to be able to and to distribute to the Class A Member the sum of (I) the amount of any Post Cover Date Basic Threshold Shortfall arising from the Disposition (and a Basic Threshold Return shall continue to accrue on the amount of such Shortfall remaining unpaid as though it were a Capital Contribution from the Class A Member until that Shortfall is paid under this Section 5.2(d)) and (II) the amount of any Post Cover Date Capital Return Shortfall arising from the Disposition. Such distribution shall be treated as made first under (I) of this Subsection and then under (II) of this Subsection. (B) Notwithstanding Section 5.2(d)(iii)(A), if the Class B Members as a group would not receive from such Common Stock disposition and from all prior dispositions of any assets by the Company an aggregate amount equal to 10% of the cumulative amount of Income of the Company through the date of the disposition of the Common Stock, then the Class B Members as a group shall first receive from the proceeds of the Common Stock disposition otherwise distributable to the Class A Members as a group under Section 5.2(d) (iii)(A) the amount necessary for the Class B Members as a group to have received that 10% amount. The balance of the proceeds from the disposition shall be distributed to the Class A Members as a group first to pay the Post Cover Date Basic Threshold Shortfall and any balance remaining to cover the Post Cover Date Capital Return Shortfall; or (C) Cause the Company to distribute to the Class A Members as a group Common Stock of sufficient value (using for the value of that Common Stock the average closing price for such stock during the 30 trading days prior to the date of the distribution) to pay the Class A Members as a group (I) the amount of any Post Cover Date Basic Threshold Shortfall arising from the Disposition (and a Basic Threshold Return shall continue to accrue on the amount of such Shortfall remaining unpaid as though it were a Capital Contribution from the Class A Members as a group until that Shortfall is paid under this Section 5.2(d)) and (II) any Post Cover Date Capital Return Shortfall arising from the Disposition. Such distribution shall be treated as made first under (I) of this Subsection and then under (II) of this Subsection. 25 (D) Notwithstanding Section 5.2(d)(iii)(C), if the Class B Members as a group would not receive from a disposition of such Common Stock if it were disposed of at the value determined under Section 5.2(d)(iii)(C) and from all prior dispositions of any assets by the Company an amount equal to 10% of the cumulative amount of Income through the date of the distribution of the Common Stock, then the Class B Members as a group shall first receive as a distribution from the Common Stock otherwise distributable to the Class A Members as a group under Section 5.2(d)(iii)(C) (valued using the average price value set forth in Section 5.2(d)(iii)(C)) such amount of Common Stock as necessary for the Class B Members as a group to have received that 10% amount. The balance of that Common Stock otherwise distributable under Section 5.2(d)(iii)(C) shall be distributed to the Class A Members as a group first to pay the Post Cover Date Basic Threshold Shortfall and any balance remaining to cover the Post Cover Date Capital Return Shortfall. (e) Notwithstanding Sections 5.2(a)-(d), in the event: (i) the net amount of U.S. federal income tax and state income tax required to be paid by a Class B Member, on the Income allocated to the Member (net of all Losses allocated to the Member hereunder and not previously offset by an allocation of Income hereunder), for any fiscal year of the Company, assuming the Class B Member were subject to the maximum individual U.S. federal and state income tax rates, using an assumed 10% state income tax rate on such Income and taking into account any deduction of state income taxes for regular U.S. federal income tax purposes, exceeds (ii) the cash distributed to the Class B Member pursuant to one or more of Sections 5.2(a)-(d) for such fiscal year or within 90 days following the close of such fiscal year, provided that to the extent that including cash distributed within such 90 day period prevents there from being an excess, such cash shall not again count for the fiscal year of distribution for purposes of determining whether there is an excess under this Section 5.2(e), (such excess being referred to as the "Class B Member's Tax Deficit"), then the Class B Member shall receive from Distributable Cash for such fiscal year or such later fiscal year when Distributable Cash becomes available, an amount equal to the Class B Member's Tax Deficit. Such distribution shall be made whether or not the Member is an individual and whether or not such income is subject to a different tax rate. Such distribution shall be taken into account in computing subsequent distributions to the Members under Sections 5.2(a)-(d). Accordingly, distributions to a Class B Member pursuant to this Section 5.2(e) shall be offset to the maximum extent possible each time out of the first subsequent distributions to which the Class B Member is otherwise entitled to under this Agreement until the amounts previously distributed to the Class Member under this Section 5.2(e) have been offset; provided that in the case of subsequent distributions not pursuant to Section 5.2(a), the Class B Member must retain sufficient cash from distributions under Section 5.2(b)(iii) and 5.2(d) to pay the Federal and state taxes attributable to the allocations related to such distributions, computed consistently with Section 5.2(e)(i). In the event that more than one Class B Member has a Tax Deficit and there is insufficient Distributable Cash for the relevant fiscal year to cover all Class B Members' Tax Deficits, distributions under this 26 Section 5.2(e) shall be made among the Class B Members with Tax Deficits in proportion to their respective Tax Deficits. (f) All distributions under this Section 5.2 shall be made only to the Persons who, according to the Company's books and records, are the holders of record of the Membership Interests in respect of which such distributions are made on the actual date of distribution. If a distribution to any Member is subject to withholding pursuant to the Code, or any other provision of federal, state or local law, the Company shall withhold all amounts otherwise distributable to such Member as are required by law and any amounts so withheld shall be deemed to have been distributed to such Member under this Agreement.

(b) A Majority Interest may base a determination that a distribution is not prohibited on any of the following bases: (i) financial statements prepared on the basis of accounting practices and principles that are reasonable in the circumstances; (ii) a fair valuation; or (iii) any other method that is reasonable in the circumstances. (c) Any Member or Assignee who receives a distribution in violation of Section 5.4(a) who knew at the time of the distribution that the distribution violated Section 5.4(a) shall be liable to the Company for the amount of the distribution.

Notwithstanding the immediately preceding sentences, if, in the determination of the Tax Matters Partner, a transfer in violation of this Article VI would cause the tax termination of the Company under Code Section 708(b)(1)(B), the transfer shall be null and void and the purported transferee shall not become either a Member or an Assignee.
