4.2.                            [Reserved]

4.3.                            Right of First Refusal.  Subject to Section 4.5, if a Member (the “First Party”) receives a bona-fide written offer by a Third Party to purchase all or a portion of the First Party’s Membership Units (the “Subject Interest”) that the First Party desires to accept, the First Party shall promptly after receipt of the offer deliver notice (the “Transfer Notice”) to the Operating Company and SKT stating that the First Party proposes to Transfer the Subject Interest. The Transfer Notice shall (i) specify the purchase price and other material terms of the Transfer of the Subject Interest, (ii) identify the proposed purchaser, (iii) specify the date scheduled for the Transfer (which date shall not be less than ninety (90) days after the date the Transfer Notice is delivered) and (iv) have attached thereto a copy of the bona fide offer and any ancillary agreements containing terms and conditions of the sale of the Subject Interest. Within sixty (60) days after receipt of a Transfer Notice, SKT shall have the right to elect to purchase a portion of the Subject Interest being sold equal to their respective ROFR Percentage Interests (a “Right of First Refusal”), on terms and conditions no less favorable to the First Party than those set forth in the Transfer Notice; provided, that if such terms and conditions include non-cash assets or non-financial requirements that would be impracticable to satisfy, then SKT shall not be required to satisfy such terms, conditions and requirements, and the purchase price for the Subject Interest will include an amount equal to the fair market value of such non-cash assets. If SKT elects to purchase the Subject Interest, the First Party and SKT shall use reasonable efforts to consummate the closing of the purchase of the Subject Interest as soon as reasonably practicable and in any event within one hundred twenty (120) calendar days after receipt of the Transfer Notice (the “ROFR Termination Date”), provided, that if the closing does not occur by then due to the failure to receive any required regulatory approvals or consents, the ROFR Termination Date may be extended by either the First Party or SKT until such approvals are received, but in no event for a period of more than one hundred eighty (180) calendar days after receipt of the

12

Transfer Notice. If the Right of First Refusal is not exercised by SKT as to the entire Subject Interest within sixty (60) days of receipt of the Transfer Notice or the entire Subject Interest is not purchased from the First Party prior to the ROFR Termination Date, as adjusted for any extension thereto, then the First Party may sell the Subject Interest to the proposed purchaser identified in the Transfer Notice on the terms set forth therein, subject to the Tag-along Right of SKT provided in Section 4.4, below. If SKT agrees to purchase any portion of the Subject Interest in accordance with the foregoing and fails to complete the purchase of such portion of the Subject Interest prior to the ROFR Termination Date, other than as a result of a denial of any required regulatory approvals or consents, then SKT shall be deemed to have breached this Agreement and, in addition to any other right or remedy available to the First Party or the Management Company, shall be deemed to have forfeited its Tag-along Right under Section 4.4 in connection with the First Party’s right to sell the Subject Interest to the Third Party named in the Transfer Notice. The above Right of First Refusal shall not apply to a transaction which constitutes a Change of Control of a Class B Member.

4.4.                            Tag-along Right. If (i) the Right of First Refusal is not exercised by SKT as to the entire Subject Interest within sixty (60) days of receipt of the Transfer Notice or the entire Subject Interest is not purchased from the First Party on or before the ROFR Termination Date, as it may have been extended or (ii) SKT receives a bona-fide written offer by a Third Party to purchase SKT’s Subject Interest that SKT desires to accept, then the First Party or SKT, as applicable, shall promptly deliver written notice thereof (“Tag-along Transfer Notice”) to any non-transferring Class B Stockholder (each non-transferring Class B Stockholder a “Second Party” and collectively, the “Second Parties”) and each Second Party will have the right to sell to the Third-Party purchaser identified in the Tag-along Transfer Notice a portion of the Subject Interest, from such Second Party’s Membership Units, equal to the Subject Interest multiplied by such Second Party’s Percentage Interest (“Tag-along Right”); provided that no Second Party that has breached its obligations under Section 4.3 with respect to any Subject Interest may exercise any Tag-along Right with respect to such Subject Interest.

14

4.6.5                     No Subject Member shall be obligated to enter into any non-competition or other restrictive covenant in connection with the Recommended Transaction unless (i) such restrictive covenant only prohibits the Subject Member from providing MVNO Services (as defined in Section 5.7.2) in the United States for a period of two (2) years, and (ii) SKT and each other Subject Member agree to such restrictive covenant in connection with the Recommended Transaction.

4.7.                            Sale of Operating Company.  Upon a sale of the Operating Company (whether by merger, unit sale, asset sale or otherwise), each Member shall receive the same proportion of the aggregate consideration from such sale that the Member would receive if there were a dissolution of the Operating Company pursuant to the terms of this Agreement.

For such purposes, each Member’s share of Additional Capital shall equal the percentage determined by dividing the Member’s Capital Contributions by the total Capital Contributions of all the Members as of such time. If, within fifteen (15) days following receipt from the Management Company of a notice specifying the amount of Additional Capital so required, a Member fails to contribute its share of such Additional Capital, then the other Members shall have the right to contribute their portion of the uncontributed Additional Capital as measured by the ratio of each Member’s share of the Additional Capital, excluding the share of Additional Capital for the non-contributing Member. If, within fifteen (15) days following receipt from the Management Company of a notice of such Member’s right to contribute its portion of uncontributed Additional Capital, the Members have failed to contribute all of such Additional Capital, the Operating Company may issue Membership Units in exchange for the contribution of the uncontributed Additional Capital, on substantially the same terms as offered to the Members, to any Person, who shall become a New Member pursuant to Section 8.2. The Operating Company shall issue Membership Units for such Additional Capital. All cash contributed by the Members (including the New Members) and all cash and investment accounts shall be held in financial institutions organized under the laws of the United States of America and deposited in accounts denominated in United States Dollars.

9.1.4                     Cancellation of Certain Initial Capital Contributions. As of the date of the SKT Triggering Contribution, Membership Units issued to EarthLink in exchange for $40,000,000 of non-cash assets contributed by EarthLink as part of the Initial Capital Contribution will be cancelled and the Percentage Interest of the Members shall be re-calculated taking into account such cancellation. In the event that the Membership Units subject to this Section 9.1.4 are cancelled upon the SKT Commitment and the $150,000,000 payable upon the SKT Triggering Contribution is not paid in full by June 30, 2008, such cancelled Membership Units will be reissued to EarthLink at no cost and the Percentage Interest of the Members shall be recalculated taking into account such issuance.

24

9.2.                            Membership Units; Capital Contributions. The Membership Units shall be considered personal property of the Member. Except as provided in this Agreement, no Member shall be entitled to the return of its Capital Contribution or to receive a distribution other than as provided in this Agreement. No return of a Member’s Capital Contributions shall be made hereunder if such distribution would violate applicable state law. Under circumstances requiring a return of any Capital Contribution, no Member shall have the right to demand or receive property other than cash, except as may be specifically provided in this Agreement.

9.3.                            Capital Accounts. An individual Capital Account shall be established and maintained for each Member in accordance with federal income tax accounting principles. The Capital Account of each Member shall be maintained in accordance with the provisions of this Section 9.3.

9.3.1                     Capital Account Increases. The Capital Account of each Member shall be increased by (a) the amount of any cash and the agreed net fair market value (as used herein, “agreed net fair market value” of property shall mean the gross fair market value of the property reduced by all liabilities encumbering the property, as determined by the Board of Directors of the Management Company as of the date of contribution) of any property contributed as a Capital Contribution to the capital of the Operating Company by such Member, (b) the amount of any profits allocated to such Member, (c) amounts of gain allocated pursuant to Section 10.3.4 and (d) amounts of gain allocated pursuant to Section 10.3.7.

9.3.2                     Capital Account Decreases. The Capital Account of each Member shall be decreased by (a) the amount of any losses allocated to such Member, (b) the amount of any cash and the agreed net fair market value as of the date of distribution of any property distributed to such Member, (c) amounts of loss allocated pursuant to Section 10.3.4 and (d) amounts of loss allocated pursuant to Section 10.3.7.

9.3.3                     Transferee Capital Accounts. A transferee of a Membership Unit shall succeed to the Capital Account (or portion of the Capital Account) attributable to such transferred Membership Unit of the transferring Member.

9.3.4                     Operating Company Options. The Operating Company shall make appropriate adjustments to Capital Accounts in connection with the exercise of an Operating Company Option. For this purpose, the Capital Account attributable to a Common Membership Unit issued upon exercise of an Operating Company Option shall include its share of unrealized income, gain, loss or deduction that is inherent in the Operating Company’s property calculated and allocated consistent with Article 10 of this Agreement and taking into account all such unrealized income, gain, loss or deduction even if reflected in all other Members’ Capital Accounts previously (other than unrealized income, gain, loss or deduction attributable to Member contributed property and specially allocable to such Member). The Operating Company will revalue its property immediately after the exercise of the Operating Company Option. For this purpose, the fair market value assigned to any property revalued by the Operating Company will be regarded as correct, provided that (i) the value is reasonably agreed to by the Members in arm’s-length negotiations and (ii) the Members have sufficiently adverse interests. Such revaluation shall be on a property-by-property basis, except as otherwise allowed. In determining the Capital Accounts of the Members (including the Management Company), the

25

Operating Company first will allocate any unrealized income, gain, loss or deduction in Operating Company property (that has not been reflected in the Capital Accounts previously) to the Management Company to the extent necessary to reflect the Management Company’s right to share in the Operating Company capital under this Agreement, and then allocate any remaining unrealized income, gain, loss or deduction (that has not been reflected in the Capital Accounts previously) to the existing Members (including the Management Company), to reflect the manner in which the unrealized income, gain, loss or deduction in Operating Company property will be allocated among those Members if there were a taxable disposition of such property for its fair market value on that date calculated consistent with Article 10 of this Agreement. If, after making the allocations described in the preceding sentence, the Management Company’s Capital Account still does not reflect the Management Company’s right to share in Operating Company capital under this Agreement, then the Operating Company will reallocate Operating Company capital between the existing Members and the Management Company so that the Management Company’s Capital Account will reflect the Management Company’s right to share in Operating Company capital under this Agreement. Any increase or reduction in the Capital Accounts of existing Members that occurs as a result of a Capital Account reallocation will have to be allocated among the existing Members in accordance with these rules. This Agreement requires corrective allocations to take into account all Capital Account reallocations according to the preceding sentence, which corrective allocations will be made until the Capital Account reallocations are eliminated. In connection with the foregoing adjustments, the fair market value of Operating Company property will be reduced by the fair market value of outstanding Operating Company Options as of the date of adjustment to the extent of the unrealized income or gain in Operating Company property (allocated in proportion to their respective amounts of unrealized appreciation).

9.3.5                     Maintenance of Capital Accounts. Notwithstanding any other provision of this Agreement, all Capital Accounts of the Members shall be determined and maintained in accordance with the capital accounting rules of Section 1.704-1(b)(2)(iv) of the Regulations.

ARTICLE 10

10.1.1              Prior Preferred Member Losses Allocated. First, profits for any Fiscal Year shall be allocated to those Preferred Members who are allocated losses pursuant to Sections 10.2.3 and 10.2.4 in proportion to and in an amount equal to any such losses allocated to such Preferred Members pursuant to Sections 10.2.3 and 10.2.4 below to restore the losses allocated to such Preferred Members with respect to their Preferred Membership Units.

10.1.2              Prior Common Member Losses Allocated. Second, profits for any Fiscal Year shall be allocated to those Common Members who are allocated losses pursuant to Sections 10.2.2 and 10.2.4 in proportion to and in an amount equal to any such losses allocated to such Common Members pursuant to Sections 10.2.2 and 10.2.4 below to restore the losses allocated to such Common Members with respect to their Common Membership Units.

26

10.1.3              Special Allocation to Common Members. Third, profits for any Fiscal Year shall be allocated to the Common Members in proportion to their respective Percentage Interests in such amounts as are necessary to cause the balances of the Capital Accounts of such Common Members, when divided by total Capital Accounts, to equal their respective Percentage Interests.

10.1.4              Percentage Interests. Fourth, profits for any Fiscal Year shall be allocated among the Members in proportion to their respective Percentage Interests.

10.2.                     Allocation of Losses. After giving effect to the special allocations set forth in Sections 10.3 and 10.4, losses for any Fiscal Year shall be allocated as follows:

10.2.1              Prior Member Profits Allocated. First, losses for any Fiscal Year shall be allocated (i) among the Members who are allocated profits pursuant to Section 10.1.4 in proportion to and in amounts equal to any such profits allocated to such Members pursuant to Section 10.1.4 to offset the profits allocated to such Members with respect to their Membership Units, and then (ii) among the Common Members who are allocated profits pursuant to Section 10.1.3 in proportion to and in amounts equal to any such profits allocated to such Common Members pursuant to Section 10.1.3 to offset the profits allocated to such Common Members with respect to their Common Membership Units.

10.2.3              Preferred Members. Third, losses for any Fiscal Year shall be allocated among the Preferred Members in proportion to their respective Percentage Interests, subject to the limitation in Section 10.2.4 below.

10.2.4              Limitation on Allocation of Losses. Losses allocated pursuant to Sections 10.2.1, 10.2.2 and 10.2.3 shall not exceed the maximum amount of losses that can be allocated without causing any Member to have an Adjusted Capital Account Deficit at the end of any Fiscal Year. In the event some, but not all, of the Members would have an Adjusted Capital Account Deficit as a consequence of an allocation of losses pursuant to Sections 10.2.1, 10.2.2 and 10.2.3 the limitations set forth in this Section 10.2.4 shall be applied on a Member by Member basis so as to allocate the maximum permissible losses to each Member under Section 1.704-1(b)(2)(ii)(d) of the Regulations. “Adjusted Capital Account Deficit” means, with respect to any Member, the deficit balance, if any, in such Member’s Capital Account as of the end of the relevant Fiscal Year, after giving effect to the following adjustments:  add to such Capital Account any amount which such Member is treated as obligated to restore pursuant to Regulations Section 1.704-1(b)(2)(ii)(c) by virtue of such Member’s guarantee or indemnity agreement with respect to any Company debt or is deemed obligated to restore pursuant to the penultimate sentences of Sections 1.704-2(g)(1) and 1.704-2(i)(5) of the Regulations; and subtract from such Capital Account the items described in Sections 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) of the Regulations. The foregoing definition of Adjusted Capital Account Deficit is intended to comply with the provisions of Section 1.704-1(b)(2)(ii)(d) of the Regulations and shall be interpreted consistently therewith.

27

10.3.                     Special Allocations. The following special allocations shall be made in the following order:

10.3.1              Minimum Gain Chargeback. Notwithstanding any other provision of this Agreement, (a) nonrecourse deductions of the Operating Company within the meaning of Section 1.704-2 of the Regulations, other than partner nonrecourse deductions within the meaning of Section 1.704-2(i), of the Regulations, shall be allocated among the Members in accordance with their respective Percentage Interests, (b) any partner nonrecourse deductions within the meaning of Section 1.704-2(i) of the Regulations, shall be allocated in accordance with Sections 1.704-2(i) and 1.704-2(k) of the Regulations, and (c) if there is a net decrease in “minimum gain” within the meaning of Sections 1.704-2(d) and 1.704-2(i)(3) of the Regulations for any Fiscal Year of the Operating Company, items of gain and income shall be allocated among the Members in accordance with the “minimum gain chargeback” rules contained in Sections 1.704-2(f) and (g) and 1.704-2(i)(4) of the Regulations. The Members’ respective interests in the Operating Company profits for purposes of allocating excess nonrecourse liabilities of the Operating Company within the meaning of Section 1.752-3(a)(3) of the Regulations shall be equal to their respective Percentage Interests.

10.3.2              Qualified Income Offset. In the event any Member unexpectedly receives any adjustments, allocations or distributions described in Sections 1.704-1(b)(2)(ii)(d)(4), (5) or (6) of the Regulations, items of Operating Company income and gain (consisting of a pro rata portion of each item of the Operating Company income, including gross income and gain for such Fiscal Year) shall be specially allocated to such Member in an amount and manner sufficient to eliminate, to the extent required by the Regulations, such deficit in the Capital Account of such Member as quickly as possible. This provision is intended to comply with the “qualified income offset” requirements of Section 1.704-1(b)(2)(ii)(d) of the Regulations, and this provision shall be interpreted in accordance with those requirements.

10.3.3              Elimination of Capital Account Deficits. In the event any Member has a deficit Capital Account at the end of any Fiscal Year which is in excess of the sum of (i) the amount such Member is treated as obligated to restore pursuant to Section 1.704-1(b)(2)(ii)(c) of the Regulations by virtue of such Member’s guarantee or indemnity with respect to Operating Company debt and (ii) the amount such Member is deemed to be obligated to restore pursuant to the penultimate sentences of Sections 1.704-2(g)(1) and 1.704-2(i)(5) of the Regulations, each such Member shall be specially allocated items of Operating Company income and gain in the amount of such excess as quickly as possible, provided that an allocation pursuant to this Section 10.3.3 shall be made only if and to the extent that such Member would have a deficit Capital Account in excess of such sum after all other allocations provided for in this Agreement have been made as if this Section 10.3.3 were not in this Agreement.

10.3.4              Adjustments to Capital Accounts. If the value for Capital Account purposes of any Operating Company property is adjusted pursuant to Section 9.3 or Section 10.3.7 hereof, 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 adjusted value in the same manner as under Section 704(c) of the Code and the Regulations thereunder.

28

10.3.5              Corrective Allocations. Corrective allocations (consisting of a pro rata portion of each item) of items of gross income and gain, or gross loss and deduction, shall be specially allocated to take into account the differences in the Operating Company’s corresponding book items as a result of Section 9.3.4.

10.3.6              Allocation of Class A Option and Other Compensation Deductions. Any deductions for compensation associated with the grant or exercise of a Class A Option, or the payments under Section 15.4, shall be allocated solely to the Management Company and without regard to the provisions of Sections 10.1 and 10.2 hereof.

10.3.7              Revaluation Upon Additional Contributions. As of the date hereof and as of the date of payment of the SKT Commitment, the Operating Company shall revalue its properties. If such revaluation results in a net book loss, such loss shall be allocated (i) first, to the Common Members in the ratio of their Capital Account balances until such balances are equal to zero; and (ii) second, to the Preferred Members so that the ratio of the Capital Account balances of such Members equal, as nearly as possible, the ratio of their Percentage Interests, after taking into account any adjustment to such Percentage Interests pursuant to Section 9.1.4. If such revaluation results in a net book gain, such gain shall be allocated to the Preferred Members so that the ratio of the Capital Account balances of such Members equal, as nearly as possible, the ratio of their Percentage Interests, after taking into account any adjustment to such Percentage Interests pursuant to Section 9.1.4.

10.4.                     Other Allocation Rules.

10.4.1              Calculation of Profits and Losses. Except as otherwise set forth in this Agreement, profits and losses of the Operating Company shall be determined for each Fiscal Year in accordance with the method of accounting followed by the Operating Company for federal income tax purposes and otherwise in accordance with GAAP, as modified by Section 1.704-1(b)(2)(iv) of the Regulations. Except as otherwise provided in this Agreement, whenever a proportionate part of the Operating Company profit or loss is allocated to a Member, every item of income, gain, loss or deduction entering into the computation of such profit and loss shall be considered allocated and every item of credit or tax preference applicable to the period during which such profit or loss was realized shall be considered allocated to such Member in the same proportion. All allocations of such items for federal income tax purposes shall be identical to the allocations set forth in this Article 10, except as otherwise required by Section 704(c) of the Code and Section 1.704-1(b)(4) of the Regulations.

10.4.2              Substantial Economic Effect. The Members intend that the allocations of profits and losses under this Agreement shall have substantial economic effect (or be consistent with the Members’ interests in the Operating Company in the case of allocation of losses attributable to nonrecourse debt) within the meaning of Section 704(b) of the Code as interpreted by the Regulations promulgated pursuant thereto. Accordingly, the provisions of Article 10 hereof and the other relevant provisions of this Agreement shall be interpreted in a manner consistent with such intent. It is the Members’ intention that the Operating Company comply with the provisions of Section 1.704-1(b) of the Regulations. However, should such section be modified in a manner that, in the event the Operating Company were to comply with

29

such section as modified, the economic intentions of the Members would be distorted, the economic intentions of the Members shall govern.

10.4.3              Closing of the Books Method. If a Member Transfers its interest in the Operating Company, the distributive shares of the various items allocable among the Members during such Fiscal Year of the Operating Company shall be allocated between the transferor and the transferee based on the closing-of-the-books method, which will result in the allocation of items between the transferor and the transferee based on the respective portions of such Fiscal Year in which each was a Member. However, if both the transferor and the transferee consent, the distributive shares of the various items allocable among the Members may be allocated between the transferor and the transferee on the basis of the number of days in such Fiscal Year preceding and following the effective date of the transfer. Moreover, the distributive share of the various items allocable among the Members as a result of (i) the exercise of an Operating Company Option in connection with the exercise of a Class A Option or warrant to purchase Class A Common Stock or (ii) the Management Company issuing any additional Class A Common Stock to third parties, shall be allocated between the transferor and transferee on the basis of the number of days in such Fiscal Year preceding and following the effective date of the transfer.

10.4.4              Built-in Gain or Loss. In accordance with Section 704(c) of the Code and the Regulations thereunder, income, gain, loss, and deduction with respect to any property contributed to the Operating Company shall, solely for federal income tax purposes, be allocated among the Members so as to take account of any variation between the tax bases of such property and such property’s fair market value as of the time of contribution to the Operating Company. Unless otherwise determined by the Management Company, such allocations shall be made pursuant to the “traditional method,” as set forth in Section 1.704-3(f) of the Regulations without curative or remedial allocations.

10.4.5              Income Tax Effects. The Members are aware of the income tax consequences of the allocations made in this Article 10 and hereby agree to be bound by the provisions of this Article 10 in reporting their shares of Operating Company income and loss for income tax purposes, except to the extent otherwise required by law.

ARTICLE 11

11.2.2              Member Loans. Second, towards repayment of outstanding loans, if any, made by Members to the Operating Company, provided, however, any amounts owed to EarthLink or SKT Holdings in connection with the Note Purchase and Security Agreement and Guaranty, dated July 23, 2007, between the Operating Company, the Management Company, EarthLink and SKT Holdings will be pari pasu with obligations set forth in Section 11.2.1.

11.2.3              Capital Accounts. Third, proceeds will be distributed to the Members in accordance with the positive balances of their Capital Accounts until such Capital Account balances are equal to zero.

11.2.4              Percentage Interests. Fourth, to the Members in accordance with their respective Percentage Interests.

11.3.                     No Withdrawal. No Member may withdraw any amount from its Capital Account except as otherwise provided in this Agreement.

11.4.                     Mandatory Tax Distribution. The Operating Company shall, to the extent that sufficient free cash flow is available, distribute to each Member on a quarterly basis the product of (i) such Member’s share of the Operating Company’s quarterly profits, and (ii) the highest marginal federal income tax rate plus five percent (5%). In the event the Operating Company’s free cash flow is insufficient to fund such distributions, the Operating Company shall make distributions of the free cash flow it has, in proportion to amounts that would otherwise be payable. Notwithstanding the foregoing, any distribution to a Common Member pursuant to this Section 11.4 shall be treated as a non-interest bearing advance of any distribution to which such Common Member might be entitled to receive pursuant to Sections 11.1 or 11.2 of this Agreement, which must be repaid to the extent such Common Members are not subsequently entitled to receive such distributions under Sections 11.1 or 11.2 of this Agreement. Any distributions to which Common Members become entitled to receive pursuant to Sections 11.1 or 11.2 above shall be withheld to repay any of the advances made pursuant to this Section 11.4.

11.5.                     Special Distribution to Management Company. Whenever any distributions are to be made to the Members with respect to a Fiscal Year pursuant to Section 11.1 above (but

31

not Sections 11.2 or 11.4), the Operating Company shall distribute to the Management Company, for (i) each holder (who is not then an employee of the Operating Company) of unexercised Class A Options which are vested at that time and/or (ii) each holder of Class A Common Stock who is not then an employee of the Operating Company or a Member, an aggregate amount of cash that equals the “Equivalent Amount” with respect to each such holder. Such distribution shall (i) be a special distribution to the Management Company, (ii) be made regardless of whether the Management Company otherwise is entitled to any such distribution pursuant to Section 11.1 and in addition to any such distribution that the Management Company is entitled to receive (determined after taking into account the reduction in the Management Company’s Capital Account resulting from the special distribution described in this Section 11.5), (iii) reduce the then aggregate distribution that otherwise would be made absent this Section 11.5 and (iv) then be paid by the Management Company with each holder (who is not then an employee of the Operating Company) of unexercised Class A Options which are vested at that time and/or each holder of Class A Common Stock who is not then an employee of the Operating Company or a Member entitled to receive such holder’s respective “Equivalent Amount.”  No distribution under this Section 11.5 shall be made to the Management Company with respect to any such Class A Options that are not vested at the time of distribution. No distributions shall be made hereunder after all of the Membership Units (other than those held by the Management Company) are exchanged for shares of Class A Common Stock pursuant to the terms of Article 15 or after a Public Offering. All distributions to be made hereunder shall be made contemporaneously with the distribution to the Members pursuant to Section 11.1, except that, in the event any portion of this special distribution would result in income to the Management Company, such as where the Management Company does not have sufficient tax basis in its Membership Units to offset the distribution or sufficient losses, including net operating loss carrybacks and carryovers, to offset the resulting income, such portion of the distribution shall not be made to the Management Company (nor shall any such related amounts be paid by the Management Company to any holder (who is not then an employee of the Operating Company) of unexercised Class A Options and/or any holder of Class A Common Stock who is not then an employee of the Operating Company or a Member). Such excess portion instead shall be an additional compensatory payment to be made under Section 15.4 to each holder entitled to receive an amount thereunder. In that case, each such holder then entitled to receive an amount under Section 15.4 shall be entitled to receive a percentage of the above excess portion equal to (i) the aggregate excess portion multiplied by (ii) a percentage, the numerator of which is the amount the holder is then entitled to receive under Section 15.4 and the denominator of which is the aggregate amounts that all holders are then entitled to receive under Section 15.4. All additional compensatory payments to be made hereunder shall be paid, less applicable tax withholdings, contemporaneously with the distribution to the Members pursuant to Section 11.1. For purposes of determining the excess portion of the special distribution to be paid as compensation under Section 15.4, any losses that would be allocated to the Management Company resulting from the compensation to be paid under this Section 11.5 shall not be counted.

11.6.                     Limitations on Distributions. No distribution shall be made if prohibited by Section 18-607 of the Act.

The Management Company shall have complete discretion to determine the time, manner and terms of any sale of the Operating Company property pursuant to such liquidation.

34

13.5.       Filing of Certificate of Cancellation. Upon the completion of the winding up of the Operating Company, the Management Company shall file a certificate of cancellation with the Secretary of State of the State of Delaware as provided in Section 18-203 of the Act.

13.6.       Material Breach. A Material Breach shall not automatically result in the termination of this Agreement. However, upon the occurrence of a Material Breach, the non-breaching party may, in addition to its rights under Section 4.6 of this Agreement, make a claim against the breaching party in its own name and in the name of the Operating Company for damages caused by the Material Breach in accordance with Article 17.

13.7.       Claims of the Members. The Members and former Members shall look solely to the Operating Company’s assets for the return of their Capital Contributions, and if the assets of the Operating Company remaining after payment of or due provision for all debts, liabilities and obligations of the Operating Company are insufficient to return such Capital Contributions, the Members and former Members shall have no recourse against the Operating Company, the Management Company or any other Member.

ARTICLE 14
WITHDRAWAL OF A MEMBER

14.1.       Withdrawal of a Member. A Member shall cease to be a Member if it no longer Beneficially Owns any Membership Units (a “Withdrawal Event”). Immediately after a Withdrawal Event, the withdrawn Member and its Affiliates shall have no continuing rights or obligations under this Agreement but will remain subject to the terms of Ancillary Agreements to the extent provided by, and in accordance with, the express terms thereof. Subject to compliance with Article 4 hereof, a Member may voluntarily cause a Withdrawal Event and such action shall not be a breach of this Agreement.

14.2.       Effect of Withdrawal. This Agreement shall continue notwithstanding any withdrawal by a Member and all governance rights set forth herein with respect to such Member shall be exercised by the remaining Member. No withdrawal shall relieve a Member of liability for any prior breach of this Agreement.

ARTICLE 15
EXCHANGE

15.1.       Exchange of Membership Units. Excluding the Management Company, a holder of Membership Units may, at its option, exchange, at any time and from time to time, any or all of its Membership Units for validly issued, fully paid and non-assessable shares of Class A Common Stock pursuant to the terms of this Article 15 and the Management Company Certificate. The number of shares of Class A Common Stock obtained from the exchange of the Membership Units shall be determined by multiplying the number of Membership Units to be exchanged by the Membership Unit Exchange Rate then in effect. Such right shall be exercised by the holder of the Membership Units to be exchanged by surrendering the certificate(s) representing the Membership Units to be exchanged to the Management Company, during normal business hours at the principal offices of the Management Company, accompanied by a written notice from the holder stating that the Membership Units are being presented for

35

exchange. Upon exercise of such exchange right, the Management Company shall issue the appropriate number of shares of Class A Common Stock to the holder of the Membership Units being exchanged and, shall be named as the record holder of the Membership Units exchanged on the books of the Operating Company. Notwithstanding the foregoing, if Preferred Membership Units are exchanged for shares of Class A Common Stock, the Preferred Membership Units being exchanged shall automatically convert into an equal number of Common Membership Units immediately prior to the exchange. As a result, the Management Company shall be named as the record holder of the Common Membership Units resulting from the conversion of the Preferred Membership Units on the books of the Operating Company. The “Membership Unit Exchange Rate” shall be initially set at one (1). In the event there is any stock split, distribution, dividend, combination (as set forth in Articles 5.13 and 5.14 of the Management Company Certificate) or similar transaction related to the Class A Common Stock in which there is not an identical combination or split or similar transaction related to the Membership Units, the Membership Unit Exchange Rate in effect immediately after such event shall be equal to the Membership Unit Exchange Rate in effect immediately before such event multiplied by (a) the number of shares of Class A Common Stock outstanding immediately after such event, and divided by (b) the number of shares of Class A Common Stock outstanding immediately before such event. In the event there is any split, combination or other similar transaction related to the Membership Units in which there is not an identical stock split, distribution, dividend, combination or similar transaction related to the Class A Common Stock, the Membership Unit Exchange Rate in effect immediately after such event shall be equal to the Membership Unit Exchange Rate in effect before such event multiplied by (a) the number of Membership Units outstanding immediately before such event, and divided by (b) the number of Membership Units outstanding immediately after such event. The Management Company agrees that upon any such surrender, the Management Company shall issue the appropriate number of shares of Class A Common Stock to the Member. No exchange of Membership Units shall be effective until such time as the appropriate number of fully paid non-assessable shares of Class A Common Stock shall have been duly issued in exchange therefor.

15.2.       Public Offering of Class A Common Stock. Upon completion of a Public Offering by the Management Company and contribution of the net proceeds from such Public Offering to the Operating Company, the Operating Company shall issue to the Management Company a number of Common Membership Units determined by dividing such net proceeds by the then average fair market value of a Preferred Membership Unit, which is the amount that would be received for such Preferred Membership Unit upon a hypothetical dissolution of the Operating Company immediately prior to the contribution of the net proceeds from such Public Offering.

15.3.       Issuance and Conversion of Preferred Stock. Upon the Management Company’s issuance of shares of Preferred Stock that are convertible to shares of Class A Common Stock and contribution of the net proceeds from such issuance to the Operating Company, the Operating Company shall issue to the Management Company a number of Common Membership Units determined by dividing such net proceeds by the then average fair market value of a Preferred Membership Unit which is the amount that would be received for such Preferred Membership Unit upon a hypothetical dissolution of the Operating Company immediately prior to the contribution of the net proceeds from the issuance of such shares of Preferred Stock. The holder of any shares of convertible Preferred Stock may exercise its right

36

to convert the shares to shares of Class A Common Stock in accordance with the terms of the Preferred Stock.

15.4.       Equity Plan Compensation. Upon the Management Company’s issuance of a Class A Option, the Management Company shall be granted a corresponding Operating Company Option. Upon the Management Company’s issuance of shares of Class A Common Stock in connection with the exercise of a Class A Option, the Management Company shall be deemed to exercise the corresponding Operating Company Option and the Management Company will contribute the exercise price of the corresponding Class A Option to the Operating Company. The Management Company shall be entitled to receive one Common Membership Unit upon exercise of an Operating Company Option in exchange for the remitted exercise price of the corresponding Class A Option. In the event there is any stock split, distribution, dividend, combination (as set forth in Articles 5.13 and 5.14 of the Management Company Certificate) or similar transaction related to the Class A Common Stock in which there is not an identical combination or split or similar transaction related to the Membership Units, the number of Common Membership Units that the Management Company will be entitled to receive in connection with the exercise of a Class A Option shall be adjusted as equitably required so as to not enlarge or dilute the purposes of this provision. Whenever any distributions are to be made to Members with respect to a Fiscal Year pursuant to Section 11.1 above (but not Sections 11.2 or 11.4), the Operating Company shall make a payment to (i) each holder (who is then an employee of the Operating Company) of unexercised Class A Options which are vested at that time and/or (ii) each holder of Class A Common Stock who is then an employee of the Operating Company an amount of cash that equals the “Equivalent Amount” with respect to each such holder, less any applicable tax withholdings. The Equivalent Amount shall be that amount which equals the product of (i) the aggregate distribution that the Management Company proposes to make to the Members pursuant to Section 11.1 above (before payments pursuant to this Section 15.4 and distributions pursuant to Section 11.5) multiplied by (ii) the percentage determined by dividing (x) the number of shares of Class A Common Stock that such holder owns or could acquire pursuant to the exercise of the holder’s vested Class A Options by (y) the sum of the Total Outstanding Shares plus the number of shares of Class A Common Stock that would be issued if all vested and unexercised Class A Options were then exercised. Such payment shall be (i) additional compensation to such holders and (ii) shall reduce the aggregate distribution that otherwise would be made under Section 11.1 absent this Section 15.4. No payments under this Section 15.4 shall be made to any holder of a Class A Option with respect to any such Class A Option that is not vested at the time of the distribution. Additionally, no payments shall be made hereunder after all of the Membership Units (other than those held by the Management Company) are exchanged for shares of Class A Common Stock pursuant to the terms of Article 15 or after a Public Offering. All payments to be made hereunder shall be made contemporaneously with the distribution to the Members pursuant to Section 11.1.

15.5.       Availability of Authorized and Unissued Class A Common Stock. The Management Company will at all times reserve and keep available a sufficient number of authorized but unissued shares of Class A Common Stock to permit the conversion of the outstanding shares of Class B Common Stock, Membership Units, and shares of convertible Preferred Stock and the exercise of any outstanding Class A Options. The Management Company covenants that if any shares of Class A Common Stock require registration with or approval of any governmental authority under any foreign, federal or state law before such

37

shares of Class A Common Stock may be issued upon such conversion or exchange, the Management Company will promptly cause such shares to be so registered or approved, as the case may be. The Management Company will use its reasonable best efforts to list the shares of Class A Common Stock required to be delivered by the Operating Company upon such conversion or exchange prior to such delivery upon each national securities exchange or other recognized trading market upon which the outstanding Class A Common Stock is listed at the time of such delivery. The Management Company covenants that all shares of Class A Common Stock that are issued, converted or exchanged as provided in this Article 15 shall, upon issuance, be validly issued, fully paid and non-assessable.

16.7.       Change of Control.

17.1.1     Negotiation Between Executives. The Members shall attempt in good faith to resolve any dispute arising out of or relating to this Agreement promptly by direct negotiation between executives who have authority to settle the controversy and who are at a higher level of management than the persons with direct responsibility for administration of this Agreement, unless there is no executive of a higher level. Any party may give the other party written notice of any dispute not resolved in the normal course of business. Within fifteen (15) days after delivery of the notice, the receiving party shall submit to the other a written response. The notice and the response shall include:  (a) a statement of each party’s position and a summary of arguments supporting that position; and, (b) the name and title of the executive who will represent that party and of any other person who will accompany the executive. Within thirty (30) days after delivery of the disputing party’s notice, the executives of each Member shall meet at a mutually acceptable time and place, and thereafter as often as they reasonably deem necessary, to attempt to resolve the dispute. All reasonable requests for information made by one party to the other will be honored. All negotiations pursuant to this clause are

41

confidential and shall be treated as compromise and settlement negotiations for purposes of applicable rules of evidence.

17.1.2     Mediation With Mutually Agreed-Upon Neutral. If the dispute has not been resolved by negotiation within forty-five (45) days of the disputing party’s notice, or if the Members fail to meet within twenty (20) days, the Members shall submit the dispute to non-binding mediation under the then-current CPR Institute for Dispute Resolution’s (“CPR”) Model Mediation Procedure for Business Disputes, and endeavor (but not be obligated) to settle the dispute in such mediation. CPR’s address at the time of this Agreement is ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇^▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇ (212-949-6490) and its website is “▇▇▇.▇▇▇▇▇▇.▇▇▇.”  The Members agree to use their reasonable best efforts and good faith to agree mutually on a mediator, to be selected from the CPR Technology Panel of Neutrals. If the Members fail to select a mutually acceptable mediator within thirty (30) days after either party’s notice to the other party that they request non-binding mediation pursuant to this subsection, CPR will appoint a mediator from the Technology Panel.

17.1.3     Arbitration. All disputes arising out of or relating to this Agreement not resolved pursuant to non-binding Mediation within thirty (30) days or as this time period may be extended by written agreement of the Members shall be settled finally in an arbitration conducted under the Rules of Arbitration of the International Chamber of Commerce (“ICC”) and as provided in this Section 17.1.3.

(f)                                    Every award shall be binding on the Members. By submitting the dispute to arbitration under the ICC Rules, the Members undertake to carry out any award without delay and shall be deemed to have waived their right to any form of recourse insofar as such waiver can validly be made.

42

(g)                                 This agreement to arbitrate shall be binding on the Members and their respective successors, assigns and Affiliates.

(h)                                 The prevailing party in any arbitration proceeding conducted pursuant to this Agreement may recover its reasonable fees both for legal representation and related costs in any action to enforce this Agreement in any judicial or arbitration proceeding.

(i)                                     The Members waive any right or claim to punitive or exemplary damages and agree that punitive or exemplary damages are not within the contemplation of this Agreement. No arbitral tribunal may order an award consisting in whole or in part of punitive or exemplary damages.

17.1.4     Tolling of Statutes of Limitation. All applicable statutes of limitation and defenses based on the passage of time shall be tolled while the procedures specified in Section 17.1.2 and Section 17.1.3 are pending. The Members will take such action, if any, required to effectuate such tolling.

17.2.       Right to Injunctive Relief Before Appointment of Arbitrators. With respect to any violations of this Agreement which would cause or might cause irreparable injury to any one of the parties to this Agreement, any party may, in addition to any other rights under this Agreement and notwithstanding the dispute resolution procedures including, particularly, the arbitration agreement contained in this Section 17.2, seek specific performance of this Agreement and injunctive relief in any court of competent jurisdiction against any ongoing violation of this Agreement. Prior to the appointment of the arbitrators pursuant to the arbitration agreement, any party hereto may seek provisional or interim measures from any court of competent jurisdiction. After the appointment of the arbitrators, the arbitrators shall have exclusive power to consider and grant requests for provisional or interim measures.
