Except as otherwise expressly provided in this Agreement, the Managing Member shall have the right to authorize and cause the Company to issue on such terms (including price) as may be determined by the Managing Member (i) subject to the limitations of Section 3.1, additional Units or other Equity Securities in the Company (including creating preferred interests or other classes or series of securities having such rights, preferences and privileges as determined by the Managing Member), and (ii) obligations, evidences of Indebtedness or other securities or interests convertible or exchangeable into Units or other Equity Securities in the Company; provided that, at any time following the date hereof, in each case the Company shall not issue Equity Securities in the Company to any Person unless such Person shall have executed a counterpart to this Agreement and all other documents, agreements or instruments deemed necessary or desirable in the discretion of the Managing Member. In that event, the Managing Member shall amend

Exhibit A to reflect such additional issuances and resulting dilution, which shall be borne pro rata by all Members based on their Units and the respective terms thereof.

          (c) Unvested Units and Vested Units. Each Management Member has been issued the number of Units set forth on Exhibit A, which identifies the number of such Management Member’s Unvested Units and Vested Units as of the date hereof. Except as set forth in Section 5.2, distributions shall not be made in respect of Unvested Units. Unvested Units shall be subject to the applicable Vesting Agreements and the Managing Member shall have sole and absolute discretion to interpret the Vesting Agreements and to adopt such amendments thereto or otherwise determine the terms and conditions of such Unvested Units in accordance with this Agreement and the applicable Vesting Agreements. The Members and the Company shall comply with the provisions of the Internal Revenue Service Revenue Procedures 93-27 and 2001-43 with respect to all such Units.

          (d) Safe Harbor. Each of the Members agrees that (i) the Company is authorized and directed to elect the safe harbor described in the proposed Revenue Procedure contained in the Internal Revenue Service Notice 2005-43 (such notice, as it may be modified or supplemented, the “Notice”) and (ii) the Company and each of its Members (including a Person to whom a membership interest is transferred in connection with the performance of services) agrees to comply with all of the requirements of the safe harbor described in the proposed Revenue Procedure with respect to all membership interests transferred in connection with the performance of services while the election is in effect. Each of the Members and the Company agrees not to report the income tax effects of the Safe Harbor Partnership Interest (as defined in the proposed Revenue Procedure Notice) to the U.S. tax authorities in a manner inconsistent with the requirements of the proposed Revenue Procedure, including the failure to provide appropriate information returns. Each of the Members acknowledges that the Notice contains a proposed Revenue Procedure and that the Notice and Revenue Procedure may undergo changes prior to their finalization. Each Member hereby irrevocably grants to the Managing Member a power-of-attorney coupled with an interest to amend this Agreement to conform to any changes to the Notice reflected in the finalized Notice and/or Revenue Procedure in order to permit the Company and its Members to qualify for the safe harbor election.

          Section 3.4 Capital Accounts. A Capital Account shall be maintained for each Member in accordance with the provisions of Treasury Regulation Section 1.704-1(b)(2)(iv) and, to the extent consistent with such regulations, the other provisions of this Agreement. The Capital Account balance of each of the Members as of the date hereof is its respective IPO Date Capital Account Balance set forth on Exhibit A. Thereafter, each Member’s Capital Account shall be (a) credited with such Member’s share of Profits, any individual items of income and gain allocated to such Member pursuant to the provisions of Article IV hereof, and the amount of additional cash, or the value as determined by the Managing Member of any asset (net of any Liabilities assumed by the Company and Liabilities to which the asset is subject) contributed to the Company by such Member, and (b) debited with the Member’s share of Losses, any

individual items of deduction and loss allocated to such Member pursuant to the provisions of Article IV hereof, the amount of any cash distributed to such Member and the value as determined by the Managing Member of any asset distributed to such Member (net of any Liabilities assumed by the Member and Liabilities to which the asset is subject).

          Section 3.5 Member Loans. Any Member may, with the approval of the Managing Member, lend or advance money to the Company or any of its Subsidiaries. Any such transaction shall be carried out on customary terms and conditions and on an arm’s length basis. If any Member shall make any loan or loans to the Company or any of its Subsidiaries, the amount of any such loan or advance shall not be treated as a Capital Contribution but shall be a debt due from the Company, unless otherwise agreed by the Members. No Member shall be obligated to make any loan or advance to the Company or any of its Subsidiaries.

          Section 3.6 Other Matters.

          (a) No Member shall demand or receive a return on or of its Capital Contributions or withdraw from the Company without the consent of the Managing Member. Under circumstances requiring a return of any Capital Contributions, no Member has the right to receive property other than cash.

          (b) No Member shall receive any interest, salary, compensation, draw or reimbursement with respect to its Capital Contributions or its Capital Account, or for services rendered or expenses incurred on behalf of the Company or otherwise in its capacity as a Member, except as otherwise provided in or contemplated by this Agreement.

          (c) The Liability of each Member shall be limited as set forth in the Act and other applicable Law and, except as expressly set forth in this Agreement or required by Law, no Member shall be personally liable for any debt or Liability of the Company, whether arising in contract, tort or otherwise, solely by reason of being a Member of the Company.

          (d) A Member shall not be required to restore a deficit balance in its Capital Account, to lend any funds to the Company or to make any additional contributions or payments to the Company.

          (e) The Company shall not be obligated for the repayment of any Capital Contributions of any Member.

          Section 3.7 Exchange of Units.

          (a) Subject to adjustment as provided in Section 3.7(d) and subject to the Managing Member’s rights described in Section 3.7(g), each of the H&F Continuing Members, the Management Members and the eRx Members shall be entitled to exchange

with the Company, at any time and from time to time, any or all of such Member’s Units (other than any Unvested Units held by the Management Members), as follows:

               (i) in the case of the H&F Continuing Members and the eRx Members, one Unit together with one share of Class B Stock will be exchangeable for one share of Class A Stock; and

               (ii) in the case of the Management Members, one Vested Unit together with one share of Class B Stock will be exchangeable for one share of Class A Stock.

Each such exchange of Units for Pubco Common Stock shall be treated for U.S. federal income tax purposes as a sale of the exchanging Member’s Units to the Managing Member in exchange for Pubco Common Stock.

          (b) In order to exercise the exchange right under Section 3.7(a), the exchanging Member shall present and surrender the certificate or certificates representing such Units and shares of Class B Stock (in each case, if certificated) during usual business hours at the principal executive offices of the Managing Member, or if any agent for the registration or transfer of shares of Class B Stock is then duly appointed and acting (the “Transfer Agent”), at the office of the Transfer Agent, accompanied by written notice (the “Exchange Notice”) to the Managing Member and the Transfer Agent stating that the exchanging Member elects to exchange with the Company a stated number of Units and shares of Class B Stock represented, if applicable, by such certificate or certificates, to the extent specified in such notice, and (if the Class A Stock to be received is to be issued other than in the name of the exchanging Member) specifying the name(s) of the Person(s) in whose name or on whose order the Class A Stock is to be issued.

          (c) If required by the Managing Member, any certificate for Units and shares of Class B Stock (in each case, if certificated) surrendered for exchange with the Company shall be accompanied by instruments of transfer, in form reasonably satisfactory to the Managing Member and the Transfer Agent, duly executed by the holder of such Units and shares of Class B Stock or such holder’s duly authorized representative. As promptly as practicable after the receipt of such notice and the surrender to the Company of the certificate or certificates, if any, representing such Units and shares of Class B Stock (but in any event by the Exchange Date, as defined below), the Managing Member shall issue and deliver to the Company, and the Company shall deliver at such office to such holder, or on such holder’s written order, a certificate or certificates, if applicable, for the number of full shares of Class A Stock issuable upon such exchange, and the Company shall deliver such shares of Class B Stock to the Managing Member. Each exchange of Units and shares of Class B Stock shall be deemed to have been effected on (i) the Business Day after the date on which the Exchange Notice shall have been received by the Managing Member or the Transfer Agent, as applicable (subject to receipt by the Managing Member or the Transfer Agent, as applicable, within three Business Days thereafter of any required instruments of transfer as aforesaid) or (ii) such later date specified in or pursuant to the Exchange

Notice (such date identified in clause (i) or (ii), as applicable, the “Exchange Date”), and the Person or Persons in whose name or names any certificate or certificates for shares of Class A Stock (which certificates shall bear any legends as may be required in accordance with applicable Law) shall be issuable upon such exchange as aforesaid shall be deemed to have become, on the Exchange Date, the holder or holders of record of the shares represented thereby. Notwithstanding anything herein to the contrary, any holder may withdraw or amend an exchange request, in whole or in part, prior to the effectiveness of the exchange, at any time prior to 5:00 p.m., New York City time, on the Business Day immediately preceding the Exchange Date (or any such later time as may be required by applicable Law) by delivery of a written notice of withdrawal to the Transfer Agent, specifying (1) the certificate numbers of the withdrawn Units and shares of Class B Stock, (2) if any, the number of Units and shares of Class B Stock as to which the Exchange Notice remains in effect and (3) if the holder so determines, a new Exchange Date or any other new or revised information permitted in an Exchange Notice. An Exchange Notice may specify that the exchange is to be contingent (including as to timing) upon the consummation of a purchase by another Person (whether in a tender or exchange offer, an underwritten offering or otherwise) of shares of the Class A Stock into which the Units and shares of Class B Stock are exchangeable, or contingent (including as to timing) upon the closing of an announced merger, consolidation or other transaction or event in which the Class A Stock would be exchanged or converted or become exchangeable for or convertible into cash or other securities or property.

          (d) In the event one class or series of Pubco Common Stock (the “Existing Securities”) is converted into another class or series of Pubco Common Stock (the “New Securities”), then an H&F Continuing Member, Management Member or eRx Member otherwise entitled to receive Existing Securities upon exchange shall instead be entitled to receive on exchange the amount of the New Securities that such Member would have received if the exchange of Units had occurred immediately before the effective date of such event and the Existing Securities received by such Member had been converted into the New Securities. No adjustments in respect of dividends or distributions on any Unit will be made on the exchange of any Unit, and if the Exchange Date with respect to a Unit occurs after the record date for the payment of a dividend or other distribution on Units but before the date of the payment, then the registered Member holding the Unit at the close of business on the record date will be entitled to receive the dividend or other distribution payable on the Unit on the payment date (without duplication of any distribution to which such holder may be entitled under Section 5.2) notwithstanding the exchange of the Unit or the default in payment of the dividend or distribution due on the Exchange Date.

          (e) The Managing Member shall at all times reserve and keep available out of its authorized but unissued Equity Securities, solely for the purpose of issuance upon exchange of Units and Class B Stock, such number of shares of Class A Stock that shall be issuable upon the exchange of all such outstanding Units and Class B Stock; provided, that nothing contained herein shall be construed to preclude the Managing Member from satisfying its obligations in respect of the exchange of the Units for shares of Class A Stock by delivery of purchased shares of Class A Stock which are

held in the treasury of the Managing Member. The Managing Member covenants that all shares of Class A Stock that shall be issued upon exchange of Units and Class B Stock shall, upon issuance thereof, be validly issued, fully paid and non-assessable.

          (f) The issuance of Class A Stock upon exchange of Units and Class B Stock shall be made without charge to the exchanging Members for any stamp or other similar tax in respect of such issuance; provided, however, that if any such shares are to be issued in a name other than that of the exchanging Member, then the Person or Persons requesting the issuance thereof shall pay to the Managing Member the amount of any tax that may be payable in respect of any transfer involved in such issuance or shall establish to the satisfaction of the Managing Member that such tax has been paid or is not payable.

          (g) (i) Notwithstanding anything to the contrary in this Section 3.7, but subject to Section 3.7(h), an exchanging Member shall be deemed to have offered to sell its or his Units (other than any Unvested Unit) and Class B Stock as described in the Exchange Notice to the Managing Member, and the Managing Member may, in its sole and absolute discretion, solely by means of delivery of Call Election Notices and/or Revocation Notices in accordance with, and subject to the terms of, this Section 3.7(g), elect to purchase directly and acquire such Units and Class B Stock on the Exchange Date by paying to the exchanging Member either (at the option of the Managing Member in its sole and absolute discretion as specified in the then-applicable Call Election Notice) (x) the Cash Amount for the shares of Class A Stock such exchanging Member would otherwise receive pursuant to Section 3.7(a) or (y) that number of shares of Class A Stock such exchanging Member would otherwise receive pursuant to Section 3.7(a), whereupon the Managing Member shall, in the case of each of clauses (x) and (y), acquire the Units and Class B Stock offered for exchange by the exchanging Member and shall be treated for all purposes of this Agreement as the owner of such Units and Class B Stock. Notwithstanding the foregoing, any purchase by the Managing Member of Units and Class B Stock that would otherwise be exchanged for shares of Class A Stock in connection with and sold in a Pubco Offer shall be for the same amount and type of consideration that the Member would have received in the Pubco Offer. In the event the Managing Member shall exercise its right to purchase Units and Class B Stock in the manner described in the first sentence of this Section 3.7(g), each of the exchanging Member, the Company and the Managing Member, as the case may be, shall treat the transaction between the Managing Member and the exchanging Member for federal income tax purposes as a sale of the exchanging Member’s Units and Class B Stock to the Managing Member. For purposes of this Section 3.7, “Cash Amount” means (A) only if the Exchange Notice for the relevant exchange provides that the exchange is to be contingent upon the consummation of a purchase by another Person (whether in a tender or exchange offer or otherwise) of shares of the Class A Stock, the amount and type of cash or other property (or combination of types of property) to which the exchanging Member would be entitled to receive in such purchase; or (B) otherwise, the amount of cash per share of Class A Stock equal to the Volume Weighted Average Price of such share of Class A Stock on the date that the Exchange Notice is delivered to the Company. The Managing Member may only pay the Cash Amount from proceeds of offerings of a number of shares of Class A Stock equal to

the number of Units covered by such Exchange Notice or pro rata distributions under Section 5.1(c).

               (ii) The Managing Member may at any time in its sole discretion deliver written notice (a “Call Election Notice”) to each other Member setting forth its election to exercise its call right as contemplated by this Section 3.7(g). Subject to the remainder of this Section 3.7(g)(ii), a Call Election Notice will be effective until such time as the Managing Member amends such Call Election Notice with a superseding Call Election Notice or revokes such Call Election Notice by delivery of a written notice of revocation delivered to each other Member (a “Revocation Notice”). A Call Election Notice may be amended or revoked by the Managing Member at any time; provided that any Exchange Notice delivered by a Member will not, without such Member’s written consent, be affected by the subsequent delivery of a Revocation Notice or by an Exchange Notice that is not effective until after the Exchange Date. Following delivery of a Revocation Notice, the Managing Member may deliver a new Call Election Notice pursuant to this Section 3.7(g). The delivery or amendment of a Call Election Notice shall not have the effect of causing the call right under this Section 3.7(g) to be exercised with respect to Units exchangeable for shares proposed to be sold in an underwritten offering, if the holders of such Units have notified the Company prior to such delivery or amendment that they contemplate undertaking such an underwritten offering (unless such holders otherwise agree in writing with the Company). Any amendment of a Call Election Notice will not be effective until thirty (30) Trading Days after its delivery to each Member (other than the Managing Member). The call right under this Section 3.7(g) shall in all events be exercised in each of the following cases either in full or not at all: (A) with respect to all Units of a Member subject to any single Exchange Notice (including as amended) or (B) with respect to all Units held by affiliated Members subject to any Exchange Notice(s) (including as amended) with the same Exchange Date.

               (iii) Each Call Election Notice shall specify:

          (1) whether the Managing Member elects to pay in the Cash Amount or in shares of Class A Stock,

          (2) the date from which it shall be effective (which shall be no earlier than thirty (30) Trading Days after delivery),

          (3) whether and to what extent the call right will be exercised with respect to exchanges made contingent upon the consummation of a purchase by another Person (in a tender or exchange offer, underwritten offering or otherwise) of shares of the Class A Stock to be issued in the exchange or to other contingent exchanges, and

          (4) at the option of the Managing Member, a limitation on the exercise of the call to Exchange Notices covering a specified minimum or maximum number of Units.

          (h) Notwithstanding any other provision of this Agreement, if a Disposition Event is approved and consummated in accordance with applicable Law, at the request of the Company (or following such Disposition Event, its successor) or the Managing Member (or following such Disposition Event, its successor), each of the H&F Continuing Members, the Management Members and the eRx Members shall be required to exchange with the Company (subject to the Managing Member’s rights described in Section 3.7(g), except that the Managing Member shall not be entitled to elect to purchase Units and shares of Class B Stock for the Cash Amount under this Section 3.7(h)), at any time and from time to time after, or simultaneously with, the consummation of such Disposition Event, all of such Member’s Units and shares of Class B Stock; provided that, in the event of a Disposition Event intended to qualify as a reorganization within the meaning of Section 368(a) of the Code or as a transfer described in Section 351(a) or Section 721 of the Code, the H&F Continuing Members, the Management Members and the eRx Members shall not be required to exchange their Units and shares of Class B Stock unless either (i) the H&F Continuing Members collectively own less than 20% of the Units and shares of Class B Stock held by them immediately prior to the IPO (after giving effect to any unit or stock split, reverse unit or stock split, unit or stock distribution or dividend or similar event) or (ii) as part of such transaction, the holders (other than the Managing Member and its Subsidiaries) of Units and shares of Class B Stock are permitted to exchange their Units and such shares for securities in a transaction that is expected to permit such exchange without current recognition of gain or loss (except to the extent that property other than securities is received in such exchange), based on a "should" or "will" level opinion from independent tax counsel of recognized standing and expertise. For the avoidance of doubt in connection with a Disposition Event, in no event shall the holders (other than the Managing Member and its Subsidiaries) of Units and shares of Class B Stock be entitled to receive aggregate consideration for each Unit and corresponding share of Class B Stock that is greater than the consideration payable in respect of each share of Class A Stock (it being understood that payments under or in respect of the Tax Receivable Agreements shall not be considered part of any such consideration).

          (i) If the Class A Stock is listed on a securities exchange, the Managing Member shall use its reasonable best efforts to cause all Class A Stock issued upon an exchange of Units to be listed on the same securities exchange at the time of such issuance.

          (j) No exchange pursuant to this Section 3.7 shall impair the right of the exchanging Member to receive any distributions payable on the Units so exchanged in respect of a record date that occurs prior to the Exchange Date for such exchange. For the avoidance of doubt, no exchanging Member shall be entitled to receive, in respect of a single record date, distributions or dividends both on Units exchanged by such Member and on Pubco Common Stock received by such Member in such exchange.

          Section 3.8 Tender Offers and Other Events with Respect to the Managing Member. In the event that a tender offer, share exchange offer, issuer bid, take-over bid, recapitalization or similar transaction with respect to Class A Stock (a “Pubco Offer”) is proposed by the Managing Member or is proposed to the Managing Member or its stockholders and approved by the board of directors of the Managing Member or is otherwise effected or to be effected with the consent or approval of the board of directors of the Managing Member, the holders (other than the Managing Member and its Subsidiaries) of Units and shares of Class B Stock shall be permitted to

participate in such Pubco Offer by delivery of a contingent Exchange Notice in accordance with the last sentence of Section 3.7(c). In the case of a Pubco Offer proposed by the Managing Member, the Managing Member will use its reasonable best efforts expeditiously and in good faith to take all such actions and do all such things as are necessary or desirable to enable and permit the holders (other than the Managing Member and its Subsidiaries) of Units and shares of Class B Stock to participate in such Pubco Offer to the same extent or on an economically equivalent basis as the holders of shares of Class A Stock without discrimination; provided that, without limiting the generality of this sentence, the Managing Member will use its reasonable best efforts expeditiously and in good faith to ensure that such holders of Units may participate in each such Pubco Offer without being required to exchange Units and shares of Class B Stock (or, if so required, to ensure that any such exchange shall be effective only upon, and shall be conditional upon, the closing of such Pubco Offer and only to the extent necessary to tender or deposit to the Pubco Offer in accordance with the last sentence of Section 3.7(c), or, as applicable, to the extent necessary to exchange the number of Units and shares being repurchased). Nothing in this Section 3.8 shall affect the right of the Managing Member to purchase Units and shares of Class B Stock, to the extent exercised under Section 3.7(g), upon the closing of such Pubco Offer for the amount per share and type of cash or other property as is paid for the Class A Stock in the Pubco Offer. For the avoidance of doubt, in no event shall the holders (other than the Managing Member and its Subsidiaries) of Units and shares of Class B Stock be entitled to receive in such Pubco Offer aggregate consideration for each Unit and corresponding share of Class B Stock that is greater than the consideration payable in respect of each share of Class A Stock in connection with a Pubco Offer (it being understood that payments under or in respect of the Tax Receivable Agreements shall not be considered part of any such consideration).

ARTICLE IV
ALLOCATIONS OF PROFITS AND LOSSES

          Section 4.1 Profits and Losses. Except as otherwise provided in this Agreement, Profits and Losses (and, to the extent necessary, individual items of income, gain, loss, deduction or credit) of the Company shall be allocated among the Members in a manner such that, after giving effect to the special allocations set forth in Sections 4.2 and 4.3, the Capital Account balance of each Member, immediately after making such allocation, is, as nearly as possible, equal to (i) the distributions that would be made to such Member pursuant to Section 10.3(b) if the Company were dissolved, its affairs wound up and its assets sold for cash equal to their Gross Asset Value, all Company Liabilities were satisfied (limited with respect to each nonrecourse Liability to the Gross Asset Value of the assets securing such Liability), and the net assets of the Company were distributed, in accordance with Section 10.3(b), to the Members immediately after making such allocation, minus (ii) such Member’s share of Company Minimum Gain and Member Minimum Gain, computed immediately prior to the hypothetical sale of assets. For purposes of the allocations determined in accordance with this Section 4.1, the amount of distributions pursuant to Section 10.3(b) shall be computed by assuming that all of the Unvested Units then outstanding are Vested Units and all Escrowed Units are Non-Escrowed Units.

          Section 4.2 Section 754 Election. The Company shall ensure that it has in effect at all times an election described in Section 754 of the Code. To the extent an adjustment to the adjusted tax basis of any Company asset pursuant to Code Section 734(b) or Code Section 743(b) is required pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of that adjustment to the Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases the basis of the asset), and such gain or loss shall be specially allocated to the Members in the manner consistent with the manner in which their Capital Accounts are required to be adjusted pursuant to that Treasury Regulation.

          Section 4.3 Regulatory and Curative Allocations; Other Allocations.

          (a) Company Minimum Gain Chargeback. Except as otherwise provided in Section 1.704-2(f) of the Treasury Regulations, notwithstanding any other provision of this Agreement, if there is a net decrease in Company Minimum Gain during any Fiscal Year, each Member shall be specially allocated items of Company income and gain for such Fiscal Year (and, if necessary, for subsequent Fiscal Years) in an amount equal to the portion of that Member’s share of the net decrease in Company Minimum Gain during such year that is allocable to the disposition of any Company assets subject to one or more Nonrecourse Liabilities of the Company. Allocations pursuant to the previous sentence shall be made in proportion to the respective amounts required to be allocated to each Member pursuant thereto. The items to be so allocated shall be determined in accordance with Treasury Regulation Section 1.704-2(j)(2)(i). Any Member’s share of any net decrease in Company Minimum Gain shall be determined in accordance with Treasury Regulation Section 1.704-2(g). This section is intended to comply with the minimum gain chargeback requirement in the Treasury Regulations and shall be interpreted consistently therewith.

          (b) Member Minimum Gain Chargeback. Notwithstanding any other provision of this Agreement except Section 4.3(a), if there is a net decrease in Member Minimum Gain attributable to Member Nonrecourse Debt during any Fiscal Year, each Member who has a share of the Member Minimum Gain attributable to such Member Nonrecourse Debt shall be specially allocated items of Company income and gain for such year (and, if necessary, subsequent years) in an amount equal to the portion of such Member’s share of the net decrease of Member Minimum Gain. Allocations pursuant to the previous sentence shall be made in proportion to the respective amounts required to be allocated to each Member pursuant thereto. The items to be so allocated shall be determined in accordance with Treasury Regulation Section 1.704-2(j)(2)(ii). Any Member’s share of the net decrease in Member Minimum Gain shall be determined in accordance with Treasury Regulation Section 1.704-2(i)(5). This section is intended to comply with the partner recourse debt minimum gain chargeback requirements in the Treasury Regulations and shall be interpreted consistently therewith.

          (c) Qualified Income Offset. In the event any Member unexpectedly receives any adjustment, allocation or distribution described in Treasury Regulation

paragraph (4), (5) or (6) of Section 1.704-1(b)(2)(ii)(d), items of income and gain shall be specially allocated to the Members in an amount and manner sufficient to eliminate, to the extent required by the Treasury Regulations, the Adjusted Capital Account Deficit of that Member as quickly as possible.

          (d) Gross Income Allocation. If any Member has a deficit Capital Account balance at the end of any Fiscal Year that is in excess of the sum of (i) the amount that such Member is obligated to restore and (ii) the amount that the Member is deemed to be obligated to restore pursuant to the penultimate sentence of Treasury Regulation Sections 1.704-2(g)(1) and (i)(5), that Member shall be specially allocated items of Company income and gain in the amount of such excess as quickly as possible, provided that an allocation pursuant to this Section 4.3(d) 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 Article IV have been made as if Sections 4.3(c) and 4.3(d) were not in this Agreement.

          (e) Nonrecourse Deductions. Nonrecourse Deductions for any Fiscal Year shall be specially allocated to the Members pro rata in proportion to their Units. The amount of Nonrecourse Deductions for a Fiscal Year shall equal the excess, if any, of the net increase, if any, in the amount of Company Minimum Gain during that Fiscal Year over the aggregate amount of any distributions during that Fiscal Year of proceeds of a Nonrecourse Liability that are allocable to an increase in Company Minimum Gain, determined in accordance with the provisions of Treasury Regulation Section 1.704-2(d).

          (f) Member Nonrecourse Deductions. Any Member Nonrecourse Deductions for any Fiscal Year shall be specially allocated to the Member who bears economic risk of loss with respect to the Member Nonrecourse Debt to which such Member Nonrecourse Deductions are attributable in accordance with Treasury Regulation Section 1.704-2(i). The amount of Member Nonrecourse Deductions with respect to a Member Nonrecourse Debt for a Fiscal Year equals the excess, if any, of the net increase, if any, in the amount of Member Minimum Gain attributable to such Member Nonrecourse Debt during that Fiscal Year over the aggregate amount of any distributions during that Fiscal Year to the Member that bears the economic risk of loss for such Member Nonrecourse Debt to the extent such distributions are from the proceeds of such Member Nonrecourse Debt and are allocable to an increase in Member Minimum Gain attributable to such Member Nonrecourse Debt, determined in accordance with Section 1.704-2(i)(1).

          (g) Curative Allocations. The allocations set forth in Sections 4.3(a) through 4.3(f) (the “Regulatory Allocations”) are intended to comply with certain requirements of Treasury Regulation Section 1.704-1(b) and 1.704-2. Notwithstanding any other provision of this Article IV (other than the Regulatory Allocations), the Regulatory Allocations (and anticipated future Regulatory Allocations) shall be taken into account in allocating other items of income, gain, loss and deduction among the Members so that, to the extent possible, the net amount of such allocation of other items and the Regulatory Allocations to each Member should be equal to the net amount that

would have been allocated to each such Member if the Regulatory Allocations had not occurred. This Section 4.3(g) is intended to minimize to the extent possible and to the extent necessary any economic distortions which may result from application of the Regulatory Allocations and shall be interpreted in a manner consistent therewith.

          Section 4.4 Allocations for Tax Purposes.

          (a) Tax Allocations. Except as otherwise provided in this Section 4.4, each item of income, gain, loss and deduction of the Company for federal income tax purposes shall be allocated among the Members in the same manner as such item is allocated under Sections 4.1 through 4.3 hereof in accordance with the provisions of Treasury Regulation Section 1.704-1(b)(2)(iv), and to the extent consistent with such regulations, the other provisions of this Agreement.

          (b) Contributed Property. Items of income, gain, loss and deduction with respect to any property contributed to the Company shall, solely for tax purposes, be allocated among the Members in accordance with Code Section 704(c) and the Treasury Regulations thereunder so as to take account of any variation between the Adjusted Basis and the initial Gross Asset Value of such property. Unless the Members otherwise agree, allocations pursuant to this Section 4.4(b) shall use the “traditional method” as set forth in Treasury Regulation Section 1.704-3(b).

          (c) Adjustments to Value of Property. In the event the Gross Asset Value of any Company asset is adjusted pursuant to subsection (b) of the definition of Gross Asset Value, subsequent allocations of income, gain, loss and deduction with respect to that asset shall take into account any variation between the Gross Asset Value of that asset before such adjustment and its Gross Asset Value after such adjustment in the same manner as the variation between Adjusted Basis and Gross Asset Value is taken into account under Section 4.4(a) hereof with respect to contributed property, and such variation shall be allocated in accordance with the principles of Treasury Regulation Section 1.704-1(b)(2)(iv)(f) and Section 4.4(b) hereof.

          (d) Recapture of Deductions and Credits. If any “recapture” of deductions or credits previously claimed by the Company is required under the Code upon the sale or other taxable disposition of any Company property, those recaptured deductions or credits shall, to the extent possible, be allocated to the Members in accordance with Treasury Regulation Section 1.1245-1(e).

          (e) Limited Application. Allocations pursuant to this Section 4.4 are solely for purposes of federal, state and local taxes and shall not affect or in any way be taken into account in computing any Member’s Capital Account or share of Profits, Losses, other items or distributions pursuant to any provision of this Agreement.

          (f) Allocation of Excess Nonrecourse Liabilities. All “excess nonrecourse liabilities,” as such term is defined in Treasury Regulation Section 1.752-3(a)(3), shall be allocated to the Members pro rata in proportion to their Units.

          Section 4.5 Other Allocation Rules.

          (a) The Members are aware of the income tax consequences of the allocations made by this Article IV and the economic impact of the allocations on the amounts receivable by them under this Agreement. The Members hereby agree to be bound by the provisions of this Article IV in reporting their share of Company income and loss for income tax purposes.

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

ARTICLE V
DISTRIBUTIONS

          Section 5.1 Amount and Time of Distributions.

          (a) Except as set forth in this Section 5.1 or Section 5.2 (including the last sentence of Section 5.2(a)), and the restrictions set forth in any class or series of Equity Securities created pursuant to Section 3.3, each distribution shall be made to the Members only at such times as the Managing Member shall reasonably determine and shall be made to the Members pro rata in proportion to their respective Units.

          (b) Notwithstanding the provisions of Section 5.1(a), a Management Member holding an Unvested Unit shall only be entitled to receive a distribution in respect of such Unvested Unit in an amount equal to the Tax Distributions with respect to such Unvested Unit in accordance with Section 5.2. The Company shall maintain in a segregated account any other amounts that were otherwise distributable to each Management Member in respect of each Unvested Unit that were not distributed as a result of this Section 5.1(b). After the end of each Fiscal Year, the Company shall distribute to each such Management Member an amount equal to the excess of (i) the aggregate amount previously distributable under Section 5.1(a) with respect to each Unvested Unit that shall have become a Vested Unit as of the end of such Fiscal Year held by such Management Member (determined without giving effect to the first sentence of this Section 5.1(b)) over (ii) the amounts previously distributed to such Management Member with respect to such Unvested Unit.

          (c) Notwithstanding the provisions of Section 5.1(a), the Managing Member, in its sole discretion, may authorize that (i) cash be paid to the Managing Member (which payment shall be made without pro rata distributions to the other Members) in exchange for the redemption, repurchase or other acquisition of the Managing Member’s Units to the extent that such cash payment is used to redeem, repurchase or otherwise acquire an equal number of shares of Class A Stock in accordance with Section 3.1(f), and (ii) to the extent that the Managing Member determines that expenses or other obligations of the Managing Member are related to its role as the managing Member of the Company or the business and affairs of the Managing Member that are conducted through the Company

or any of the Company’s direct or indirect Subsidiaries, cash distributions be made to the Managing Member (which distributions shall be made without pro rata distributions to the other Members) in amounts required for the Managing Member to pay (A) operating, administrative and other similar costs incurred by the Managing Member, including payments in respect of Indebtedness and preferred stock, to the extent used or will be used by the Managing Member to pay expenses or other obligations described in this clause (ii) (in either case only to the extent economically equivalent Indebtedness or Equity Securities of the Company were not issued to the Managing Member), payments representing interest with respect to payments not made when due under the terms of the Tax Receivables Agreements and payments pursuant to any legal, tax, accounting and other professional fees and expenses (but, for the avoidance of doubt, excluding any tax liabilities of the Managing Member), (B) any judgments, settlements, penalties, fines or other costs and expenses in respect of any claims against, or any litigation or proceedings involving, the Managing Member, (C) fees and expenses related to any securities offering, investment or acquisition transaction (whether or not successful) authorized by the board of directors of the Managing Member and (D) other fees and expenses in connection with the maintenance of the existence of the Managing Member (including any costs or expenses associated with being a public company listed on a national securities exchange). For the avoidance of doubt, distributions made under this Section 5.1(c) may not be used to pay or facilitate dividends or distributions on the Pubco Common Stock.

          (d) Except as otherwise provided in this Agreement, any distributions may be made in cash or in kind, or partly in cash and partly in kind, as determined by the Managing Member. Upon any distribution in kind, the distribution shall be treated as if the property were sold for its Gross Asset Value, and the proceeds therefor distributed to the Members. The deemed gain or loss on such disposition shall be included in the calculation of Profit and Loss for the period in which the distribution occurred.

          Section 5.2 Tax Distributions.

          (a) With respect to each Fiscal Year, the Company shall make distributions to each Member pro rata in accordance with their respective Annual Target Tax Distributions. The “Annual Target Tax Distribution” of a Member shall mean the product of (i) the excess of the Company’s total taxable income allocable to the Member in respect of such Fiscal Year over taxable losses allocated to the Member in prior Fiscal Years and, in the case of the Managing Member, in the period commencing on the Original Effective Date and ending on the Subsequent Effective Date, to the extent such losses have not previously been taken into account to reduce taxable income pursuant to this provision (ignoring partner level Section 743 adjustments except as described in subparagraph (c) below), and (ii) the highest maximum combined marginal federal, state and local income tax rates generally applicable to an individual resident (or, if higher, a corporation resident) in New York City, New York may be subject. Amounts distributed pursuant to this Section 5.2 shall be referred to as “Tax Distributions.” Tax Distributions pursuant to this Section 5.2(a) shall be estimated by the Tax Matters Member on a quarterly basis and, to the extent feasible (as determined with the approval of the

disinterested members of the board of directors of the Managing Member including a majority of the Independent Directors (as defined in the Stockholders Agreement) in the case of Tax Distributions to the eRx Members), shall be distributed to the Members (together with a statement showing the calculation of such Tax Distribution and an estimate of taxable income allocable to each Member for such period) on a quarterly basis on the date that is five Business Days prior to whichever of April 15th, June 15th, September 15th or December 15 falls (or other dates for which corporations are required to make quarterly estimated tax payments for U.S. federal income tax purposes) (a “Quarterly Tax Distribution”) within the relevant quarter to facilitate the payment of estimated taxes by the Members or their beneficial owners. Quarterly Tax Distributions shall be based upon the estimated taxable income of the Company for the Fiscal Year through the end of the month prior to the month in which such Quarterly Tax Distribution is made (and shall (A) utilize the same methodology for calculating the amount of such Quarterly Tax Distribution described above for Annual Target Tax Distributions and (B) take into account prior Tax Distributions made with respect to such Fiscal Year); provided, that with respect to the final Quarterly Tax Distribution for a Fiscal Year, such distribution shall be based upon taxable income of the Company for the full Fiscal Year. A final accounting for Tax Distributions shall be made for each taxable year after the Company’s actual taxable income has been determined and (x) any shortfall in the amount of Tax Distributions the Members received for such taxable year based on such final determination shall promptly be distributed to such Members, and (y) any excess in the amount of Tax Distributions the Members received for such taxable year shall be applied against the subsequent Tax Distributions due to such Members. Tax Distributions to a Member (other than Nonrefundable Tax Distributions) shall be offset against and reduce subsequent distributions (other than Tax Distributions) to which a Member would otherwise be entitled to receive pursuant to Section 5.1 and/or Section 10.3 of this Agreement.

          (b) In the event of any audit adjustment by a taxing authority which affects the calculation of the Annual Target Tax Distribution for any Fiscal Year, or in the event the Company files an amended return which has such effect, the Annual Target Tax Distribution with respect to such year shall be recalculated by giving effect to such audit adjustment or changes reflected in the amended return, as applicable (and by including therein an additional amount that, when distributed to the Members pursuant to this sentence, will be sufficient to cover any interest or penalties incurred by any of Member or former Member in connection therewith), and the Members and former Members who were Members during the relevant tax year shall be entitled to an additional distribution or shall refund any overpayment required on the basis of such audit recalculated Annual Target Tax Distribution amount.

          (c) Solely for purposes of computing Annual Target Tax Distributions, the Company’s taxable income or loss shall be computed on the basis that the common tax bases of the Company’s assets were adjusted on the Original Effective Date in a manner that corresponds to (i) the Section 743 adjustments of the Managing Member in respect of such assets as of the Original Effective Date, divided by (ii) 52%, except to the extent otherwise agreed by the H&F Continuing Members and the Managing Member.

For purposes of this calculation, the deemed increases or decreases in the tax bases of the Company’s assets described in the preceding sentence will be treated in the same manner as the Section 743 adjustments of the Managing Member with respect to such assets. For example, if the Managing Member received a partner level amortizable basis adjustment to goodwill of $190 million in respect of its Units on the Original Effective Date, the Company may be treated for purposes of computing Annual Target Tax Distributions as having received a hypothetical common basis adjustment to amortizable goodwill of $365 million (190 divided by 0.52) on the Original Effective Date. For the avoidance of doubt, the Section 743 adjustments of the H&F Continuing Members, the Section 743 adjustment of HF Pubco Sub and the Section 743 adjustment of GA Pubco Sub as a result of the transactions contemplated by the Purchase Agreement shall not be taken into account for purposes of calculating Tax Distributions under this Section 5.2(c).

          (d) In addition to the foregoing but subject to any restrictions set forth in any Indebtedness of the Company, the Company shall make distributions five Business Days prior to June 1st and December 1st of each Fiscal Year to the Members pro rata in proportion to their respective Units such that the Managing Member shall receive an amount pursuant to this Section 5.2(d) equal to any tax that (i) is not determined on the basis of the Company’s taxable income but is payable by the Managing Member due to the Managing Member’s ownership of Units in the Company and (ii) accrues as of such June 1st or December 1st for the current or any prior Fiscal Year but with respect to which no prior distribution has been made pursuant to this Section 5.2(d). For the avoidance of doubt, distributions made pursuant to this Section 5.2(d) shall be determined by reference to certain tax liabilities of the Managing Member but shall be made to all Members on a pro rata basis.

          Section 5.3 Distribution Upon Withdrawal. No withdrawing Member shall be entitled to receive any distribution or the value of such Member’s Interest in the Company as a result of withdrawal from the Company prior to the liquidation of the Company, except as specifically provided in this Agreement.

ARTICLE VI
MANAGEMENT

          Section 6.1 The Managing Member; Fiduciary Duties.

          (a) Pubco shall be the sole managing Member of the Company. Except as otherwise required by Law, (i) the managing Member shall have full and complete charge of all affairs of the Company, (ii) the management and control of the Company’s business activities and operations shall rest exclusively with the managing Member, and the managing Member shall make all decisions regarding the business, activities and operations of the Company (including the incurrence of costs and expenses) in its sole discretion without the consent of any other Member and (iii) the Members other than the managing Member (in their capacity as such) shall not participate in the control, management, direction or operation of the activities or affairs of the Company and shall have no power to act for or bind the Company.

          (b) In connection with the performance of its duties as the managing Member of the Company, the managing Member acknowledges that it will owe to the Members the same fiduciary duties as it would owe to the stockholders of a Delaware corporation if it were a member of the board of directors of such a corporation and the Members were stockholders of such corporation. The parties acknowledge that the Managing Member will take action through its board of directors, and that the members of the Managing Member’s board of directors will owe comparable fiduciary duties to the stockholders of the Managing Member. The Managing Member will use all commercially reasonable and appropriate efforts and means, as determined in good faith by the Managing Member, to minimize any conflict of interest between the Members, on the one hand, and the stockholders of the Managing Member, on the other hand, and to effectuate any transaction that involves or affects any of the Company, the Managing Member, the Members and/or the stockholders of the Managing Member in a manner that does not (i) disadvantage the Members or their interests relative to the stockholders of the Managing Member or (ii) advantage the stockholders of the Managing Member relative to the Members or (iii) treats the Members and the stockholders of the Managing Member differently; provided, that in the event of a conflict between the interests of the stockholders of the Managing Member and the interests of the other Members, the other Members agree that the Managing Member shall discharge its fiduciary duties to the other Members by acting in the best interests of the Managing Member’s stockholders.

          Section 6.2 Officers.

          (a) The managing Member may appoint, employ or otherwise contract with any Person for the transaction of the business of the Company or the performance of services for or on behalf of the Company, and the managing Member may delegate to any such Persons such authority to act on behalf of the Company as the managing Member may from time to time deem appropriate.

          (b) The initial president and chief executive officer of the Company (the “President and Chief Executive Officer”) will be ▇▇▇▇▇▇ ▇▇▇▇▇▇▇, subject to the terms of the employment agreement between EBS LLC and ▇▇▇▇▇▇ ▇▇▇▇▇▇▇, dated as of March 29, 2007 (as the same may be amended from time to time).

          (c) Except as otherwise set forth herein, the President and Chief Executive Officer will be responsible for the general and active management of the business of the Company and its Subsidiaries and will see that all orders of the Managing Member are carried into effect. The President and Chief Executive Officer will report to the managing Member and have the general powers and duties of management usually vested in the office of president and chief executive officer of a corporation organized under the DGCL, subject to the terms of this Agreement, and will have such other powers and duties as may be prescribed by the managing Member or this Agreement. The President and Chief Executive Officer will have the power to execute bonds, mortgages and other contracts requiring a seal, under the seal of the Company, except where required or permitted by Law to be otherwise signed and executed, and except where the

signing and execution thereof will be expressly delegated by the managing Member to some other officer or agent of the Company.

          (d) Except as set forth herein, the managing Member may appoint officers at any time, and the officers may include one or more vice presidents, a secretary, one or more assistant secretaries, a chief financial officer, a general counsel, a treasurer, one or more assistant treasurers, a chief operating officer, an executive chairman, and any other officers that the managing Member deems appropriate. Except as set forth herein, the officers will serve at the pleasure of the managing Member, subject to all rights, if any, of such officer under any contract of employment. Any individual may hold any number of offices, and an officer may, but need not, be a Member of the Company. The officers will exercise such powers and perform such duties as specified in this Agreement or as determined from time to time by the managing Member.

          (e) Subject to this Agreement and to the rights, if any, of an officer under a contract of employment, any officer may be removed, either with or without cause, by the managing Member. Any officer may resign at any time by giving written notice to the managing Member. Any resignation will take effect at the date of the receipt of that notice or at any later time specified in that notice; and, unless otherwise specified in that notice, the acceptance of the resignation will not be necessary to make it effective. Any resignation is without prejudice to the rights, if any, of the Company under any contract to which the officer is a party. A vacancy in any office because of death, resignation, removal, disqualification or any other cause will be filled in the manner prescribed in this Agreement for regular appointments to that office.

          Section 6.3 Warranted Reliance by Officers on Others. In exercising their authority and performing their duties under this Agreement, the officers shall be entitled to rely on information, opinions, reports, or statements of the following persons or groups unless they have actual knowledge concerning the matter in question that would cause such reliance to be unwarranted:

          (a) one or more employees or other agents of the Company or in subordinates whom the officer reasonably believes to be reliable and competent in the matters presented; and

          (b) any attorney, public accountant, or other person as to matters which the officer reasonably believes to be within such person’s professional or expert competence.

          Section 6.4 Indemnification of the Managing Member, Officers and the Tax Matters Member.

          (a) Unless otherwise provided in Section 6.4(d), the Company, its receiver or its trustee (in the case of its receiver or trustee, to the extent of the assets of the Company) shall indemnify, save harmless, and pay all judgments and claims against the managing Member, any of the officers or the Tax Matters Member (each, an “Indemnified Person”) relating to any Liability or damage incurred by reason of any act

performed or omitted to be performed by any Indemnified Person (in such capacity) in good faith relating to or in connection with the business or affairs of the Company, including reasonable attorneys’ fees incurred by the Indemnified Person in connection with the defense of any action based on any such act or omission, which attorneys’ fees shall be paid as incurred. In the event it is later determined that the Indemnified Person was not entitled to any attorneys’ fees paid to it in accordance with this Section 6.4(a), such Indemnified Person shall promptly reimburse the Company for such payments together with interest on such amounts accruing from the date of advancement of such payments until the date of repayment (calculated on the basis of a 360 day year) at the Prime Rate as in effect from time to time.

          (b) Unless otherwise provided in Section 6.4(d), in the event of any action by a Member against any Indemnified Person, including a Company derivative suit, the Company shall indemnify, save harmless, and pay all expenses of such Indemnified Person, including reasonable attorneys’ fees, incurred in the defense of such action.

          (c) Unless otherwise provided in Section 6.4(d), the Company shall indemnify, save harmless and pay all expenses, costs, or Liabilities of any Indemnified Person, if for the benefit of the Company, at the direction of the managing Member, and in accordance with this Agreement if said Indemnified Person makes any deposit or makes any other similar payment or assumes any obligation in connection with any business proposed to be acquired by the Company and suffers any financial loss as the result of such action.

          (d) Notwithstanding the provisions of Sections 6.4(a), 6.4(b) and 6.4(c) above, (i) such Sections shall be enforced only to the maximum extent permitted by Law and (ii) no Indemnified Person shall seek or be entitled to indemnification for any fraud, intentional misconduct, gross negligence or knowing violation of the Law made or committed by his, her or itself or any of his, her or its Affiliates which was material to the cause of action or other matter giving rise to a potential claim for indemnification.

          (e) An Indemnified Person shall be fully protected in relying in good faith upon the records of the Company and upon such information, opinions, reports or statements presented to the Company by any Person as to matters the Indemnified Person reasonably believes are within such other Person’s professional or expert competence, including information, opinions, reports or statements as to the value and amount of the assets, Liabilities, Profits or Losses or any other facts pertinent to the existence and amount of assets from which distributions to Members might properly be paid.

          (f) The obligations of the Company set forth in this Section 6.4 are expressly intended to create third party beneficiary rights of each of the Indemnified Persons and shall survive any termination of this Agreement.

          Section 6.5 Maintenance of Insurance or Other Financial Arrangements. In compliance with applicable Law, the Company (with the approval of the managing Member) may purchase and maintain insurance or make other financial

arrangements on behalf of any Person who is or was a Member, employee or agent of the Company, or at the request of the Company is or was serving as a manager, director, officer, employee or agent of another limited liability company, corporation, partnership, joint venture, trust or other enterprise, for any Liability asserted against such Person and Liability and expenses incurred by such Person in such Person’s capacity as such, or arising out of such Person’s status as such, whether or not the Company has the authority to indemnify such Person against such Liability and expenses.

          Section 6.6 Resignation or Termination of Managing Member. Pubco shall not, by any means, resign as, cease to be or be replaced as managing Member except in compliance with this Section 6.6. No termination or replacement of Pubco as managing Member shall be effective unless proper provision is made, in compliance with this Agreement, so that the obligations of Pubco, its successor (if applicable) and any new managing Member and the rights of all Members under this Agreement and applicable Law remain in full force and effect. No appointment of a Person other than Pubco (or following a Disposition Event, its successor) as managing Member shall be effective unless Pubco (or its successor, as applicable) and the new managing Member (as applicable) provide all other Members with contractual rights, directly enforceable by such other Members against Pubco (or its successor, as applicable) and the new managing Member (as applicable), to cause (a) Pubco to comply with all Pubco’s obligations under this Agreement (including its obligations under Section 3.7) other than those that must necessarily be taken in its capacity as managing Member and (b) the new managing Member to comply with all the managing Member’s obligations under this Agreement.

          Section 6.7 No Inconsistent Obligations. Managing Member represents that it does not have any contracts, other agreements, duties or obligations that are inconsistent with its duties and obligations (whether or not in its capacity as Managing Member) under this Agreement and covenants that, except as permitted by Section 6.1, it will not enter into any contracts or other agreements or undertake or acquire any other duties or obligations that are inconsistent with such duties and obligations.

          Section 6.8 Reclassification Events of Pubco. If a Reclassification Event occurs, the Managing Member or its successor, as the case may be, shall, as and to the extent necessary, amend this Agreement in compliance with Section 11.1, and enter into any necessary supplementary or additional agreements, to ensure that, following the effective date of the Reclassification Event: (i) the exchange rights of holders of Units set forth in Section 3.7 provide that each Unit and share of Class B Stock is exchangeable for the same amount and same type of property, securities or cash (or combination thereof) that one share of Class A Stock becomes exchangeable for or converted into as a result of the Reclassification Event and (ii) Pubco or the successor to Pubco, as applicable, is obligated to deliver such property, securities or cash upon such exchange. Pubco shall not consummate or agree to consummate any Reclassification Event unless the successor Person, if any, becomes obligated to comply with the obligations of Pubco (in whatever capacity) under this Agreement. For the avoidance of doubt, the provisions of this Section 6.8 shall not affect the right of the Company or the Managing Member to require an exchange pursuant to Section 3.7(h) upon the consummation of a Disposition Event.

          Section 6.9 Managing Member Dividends and Distributions. Except as otherwise determined by the Managing Member with the consent of the H&F Continuing Members, the Managing Member shall not make any dividend or other distribution on any shares of Class A Stock (other than a dividend payable entirely in shares of capital stock of the Managing Member that is made in accordance with Section 3.1(g)) except solely with the proceeds of distributions received by the Managing Member in respect of Units pursuant to Section 5.1(a) (which, for the avoidance of doubt, does not include Tax Distributions) that were paid pro rata to all holders of Units.

ARTICLE VII
ROLE OF MEMBERS

          Section 7.1 Rights or Powers.

          (a) Other than the Managing Member, the Members, acting in their capacity as Members, shall not have any right or power to take part in the management or control of the Company or its business and affairs or to act for or bind the Company in any way. Notwithstanding the foregoing, the Members have all the rights and powers specifically set forth in this Agreement and, to the extent not inconsistent with this Agreement, in the Act. A Member, any Affiliate thereof or an employee, stockholder, agent, director or officer of a Member or any Affiliate thereof, may also be an employee or be retained as an agent of the Company. The existence of these relationships and acting in such capacities will not result in the Member (other than the Managing Member) being deemed to be participating in the control of the business of the Company or otherwise affect the limited liability of the Member. Except as specifically provided herein, a Member (other than the Managing Member) shall not, in its capacity as a Member, take part in the operation, management or control of the Company’s business, transact any business in the Company’s name or have the power to sign documents for or otherwise bind the Company.

          (b) The Company shall, from time to time, as and when required, cause EBS LLC and each of the Company’s other Subsidiaries to make distributions upon their respective equity interests in aggregate amounts necessary to allow the Company to make Tax Distributions to the Members as provided in Section 5.2(a).

          Section 7.2 Voting.

          (a) Meetings of the Members may be called upon the written request of Members holding at least 5% of the outstanding Units. Such request shall state the location of the meeting and the nature of the business to be transacted at the meeting. Written notice of any such meeting shall be given to all Members not less than two Business Days nor more than 30 days prior to the date of such meeting. Members may vote in person, by proxy or by telephone at any meeting of the Members and may waive advance notice of such meeting; provided, that the eRx Members shall not be entitled to any vote at such meeting with respect to eRx Units. Whenever the vote or consent of Members is permitted or required under this Agreement, such vote or consent may be given at a meeting of the Members or may be given in accordance with the procedure

prescribed in this Section 7.2. Except as otherwise expressly provided in this Agreement, the affirmative vote of the Members holding a majority of the outstanding Units, excluding eRx Units held by eRx Members, shall constitute the act of the Members.

          (b) Each Member may authorize any Person or Persons to act for it by proxy on all matters in which such Member is entitled to participate, including waiving notice of any meeting, or voting or participating at a meeting. Every proxy must be signed by such Member or its attorney-in-fact. No proxy shall be valid after the expiration of 11 months from the date thereof unless otherwise provided in the proxy. Every proxy shall be revocable at the pleasure of the Member executing it.

          (c) Each meeting of Members shall be conducted by an officer designated by the Managing Member or such other individual person as the Managing Member deems appropriate.

          (d) Any action required or permitted to be taken by the Members may be taken without a meeting if the requisite Members whose approval is necessary consent thereto in writing.

          Section 7.3 Various Capacities. The Members acknowledge and agree that the Members or their Affiliates will from time to time act in various capacities, including as a Member and as the Tax Matters Member.

ARTICLE VIII
TRANSFERS OF INTERESTS

          Section 8.1 Restrictions on Transfer.

          (a) Except as provided in Section 3.7 and Section 8.1(c) and except for the Transfers (i) by an H&F Continuing Member to an H&F Permitted Transferee, (ii) by a Management Member to a Management Permitted Transferee, provided, that any and all such Transfers shall not at any time result in greater than sixteen (16) Management Members (including Management Permitted Transferees) as parties to this Agreement or (iii) by an eRx Member of Non-Escrowed Units to an eRx Permitted Transferee, provided, that any and all such Transfers shall not at any time result in greater than eight (8) eRx Members (including eRx Permitted Transferees) as parties to this Agreement, no Member shall, nor shall its direct and indirect equity holders, Transfer all or any portion of its Interest, directly or indirectly, without the prior written consent of the Managing Member. If, notwithstanding the provisions of this Section 8.1(a), all or any portion of a Member’s Interests are Transferred in violation of this Section 8.1(a), involuntarily, by operation of law or otherwise, then without limiting any other rights and remedies available to the other parties under this Agreement or otherwise, the Transferee of such Interest (or portion thereof) shall not be admitted to the Company as a Member or be entitled to any rights as a Member hereunder, and the Transferor will continue to be bound by all obligations hereunder, unless the Managing Member consents in writing to such admission, which consent shall be granted or withheld in the Managing Member’s sole discretion. Any attempted or purported Transfer of all or a portion of a Member’s

Interests in violation of this Section 8.1(a) shall be null and void and of no force or effect whatsoever. In the event a Transfer of any Interests (other than a Transfer of Interests pursuant to Section 3.7) causes a termination of the Company for tax purposes under Section 708 of the Code, the transferring Member shall indemnify and hold harmless the other Members with respect to the net amount of any incremental tax costs resulting from such termination. For the avoidance of doubt, the restrictions on Transfer contained in this Article VIII shall not apply to the Transfer of any capital stock of the Managing Member; provided that no shares of Class B Stock may be Transferred unless a corresponding number of Units are Transferred therewith in accordance with this Agreement.

          (a) If the Company receives proceeds in respect of which a tax has been withheld, the Company shall be treated as having received cash in an amount equal to the amount of such withheld tax, and, for all purposes of this Agreement but subject to Section 9.6(d), each Member shall be treated as having received a distribution pursuant to Section 5.1 equal to the portion of the withholding tax allocable to such Member, as determined by the Managing Member in its discretion.

          (b) The Company is authorized to withhold from any payment made to, or any distributive share of, a Member any taxes required by Law to be withheld.

          (c) Neither the Company nor the Managing Member shall be liable for any excess taxes withheld in respect of any Member, and, in the event of

overwithholding, a Member’s sole recourse shall be to apply for a refund from the appropriate Governmental Entity.

          (d) Any taxes withheld pursuant to Sections 9.6(a) or 9.6(b) shall be treated as if distributed to the relevant Member to the extent an amount equal to such withheld taxes would then be distributable to such Member, and, to the extent in excess of such distributable amounts, as a demand loan payable by the Member to the Company with interest at the Prime Rate in effect from time to time, compounded annually. The Managing Member may, in its discretion, either demand payment of the principal and accrued interest on such demand loan at any time, and enforce payment thereof by legal process, or may withhold from one or more distributions to a Member amounts sufficient to satisfy such Member’s obligations under any such demand loan.

          (e) If the Company is required by Law to make any payment to a Governmental Entity that is specifically attributable to a Member or a Member’s status as such (including federal withholding taxes, state personal property taxes, and state unincorporated business taxes), then such Member shall indemnify and contribute to the Company in full for the entire amount of taxes paid (plus interest, penalties and related expenses if the failure of the Company to make such payment is due to the fault of the Member) (which payment shall not be deemed a Capital Contribution for purposes of this Agreement). The Managing Member may offset distributions to which a Person is otherwise entitled under this Agreement against such Person’s obligation to indemnify the Company under this Section 9.6.

          (f) If the Company, the Managing Member or any of their respective Affiliates, or any of their respective shareholders, partners, members, officers, directors, employees, managers and, as determined by the Managing Member in its discretion, consultants or agents, becomes liable as a result of a failure to withhold and remit taxes in respect of any Member, then such Member shall provide evidence satisfactory to the Managing Member that it has paid the taxes to which the failure to withhold relates and, to the fullest extent permitted by Law, indemnify and hold harmless the Company, the Managing Member or any of their respective Affiliates, or any of their respective shareholders, partners, members, officers, directors, employees, managers and, as determined by the Managing Member in its discretion, consultants or agents, as the case may be, in respect of all taxes, including interest and penalties, and any expenses incurred in any examination, determination, resolution and payment of such liability if the liability for failure to withhold and remit taxes was due to the fault of the Member. The provisions contained in this Section 9.6(f) shall survive the termination of the Company, the termination of this Agreement and the Transfer of any Interest.

          (g) In the event that the Company receives a refund of taxes previously withheld by a third party from one or more payments to the Company, the economic benefit of such refund shall be apportioned among the Members in a manner reasonably determined by the Managing Member to offset the prior operation of this Section 9.6 in respect of such withheld taxes.
